BATTERY RETAINING STRUCTURE OF A VEHICLE

HERO MOTOCORP LIMITED, an Indian Company at: The Grand Plaza, Plot No.2, Nelson Mandela Road, Vasant Kunj- Phase -II, New Delhi, India, 110 070

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION:
[01] The present invention relates to a battery retaining structure of a vehicle, more particularly to a battery retaining structure of an electric vehicle.

BACKGROUND OF THE INVENTION:
[02] A frame body is an essential part of a vehicle and traditionally were originally designed to accommodate internal combustion engines and their associated vehicular components. However, with the recent developments in field of electric vehicles, the role of the frame body has been tremendously changed. For example, the electric vehicle comprises at least one storage compartment mounted on the frame body for accommodating at least one battery providing power to the electric vehicle. In such cases, the storage compartment is held in a secure manner with respect to the frame body.

[03] However, it has been observed securely holding the storage compartment with respect to the frame body in itself is not sufficient. The battery in itself may experience un-wanted movement due to the movement of the vehicle, which can result in disruption in supply of electrical energy from the one or more battery to the motor which is providing power to the electrical vehicle. In many cases, the storage compartment in itself is designed in a way to prohibit movement of the battery therein. However, such a construction hampers in easy removal of the battery from the storage compartment. Alternatively, and especially in cases, wherein the storage compartment is placed below a seat, the seat is made to restrict un-desired movement of the at least one battery. This alternative approach casts serious limitations in terms of construction of the seat and various other vehicular components.

[04] Thus, there exists a need to provide a battery retaining structure of a vehicle which securely holds the battery and inhibits the battery from exhibiting un-wanted movement. Also, the construction of the battery retaining structure should be such that it does not hamper in removal or insertion of the battery into the storage compartment.

SUMMARY OF THE INVENTION:
[05] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[06] Accordingly, the present invention provides a battery retaining structure of a vehicle, comprising a latching element connected to a frame body of the vehicle, the latching element adapted to receive a counter latching element and retain a storage compartment in a latched state. The storage compartment storing at least one battery. The battery retaining structure further comprises an actuating member acting upon the latching element and being adapted to, upon actuation, permit the storage compartment to reach an un-latched state with respect to the latching element. The battery retaining structure further comprises and a movement restricting mechanism connected to the frame body, the movement restricting mechanism inhibiting movement of the at least one battery when the storage compartment is in the latched state.

[07] In an embodiment of the invention, the movement restricting mechanism exhibits pivotal movement with respect to the frame body and inhibits movement of the at least one battery in a vehicular upward direction when the storage compartment is in the latched state.

[08] In another embodiment of the invention, the movement restricting mechanism comprises a first arm, a second arm protruding from the first arm, and a bracket element connecting the movement restricting mechanism to the frame body of the vehicle.

[09] In yet another embodiment of the invention, the movement restricting mechanism exhibits pivoting movement between a first state and a second state. When the movement restricting mechanism is in the first state and when the storage compartment is in the latched state and the movement restricting mechanism inhibits movement of the battery in a vehicular upward direction.

[010] In still another embodiment of the invention, the second arm protrudes substantially perpendicularly from the first arm.

[011] In a further embodiment of the invention, the movement restricting mechanism is coupled to the bracket element vide a pivot axis defining element.

[012] In a furthermore embodiment of the invention, the movement restricting mechanism comprises a first roller provided on the first arm. The first roller comes in contact with a top surface of the battery to inhibit movement of the battery in a vehicular upward direction when the movement restricting mechanism is in the first state and the storage compartment is in the latched state.

[013] The invention further provides an electrical vehicle, comprising a frame body supporting at least one ground engaging member, at least one motor unit supplying driving power to at least one ground engaging member, and at least one battery providing electrical power to the at least one motor unit. The electrical vehicle further comprises at least one storage compartment storing the at least one battery. The at least one storage compartment is pivotally supported by the frame body. The electrical vehicle further comprises a battery retaining structure retaining the at least one battery. In an embodiment of the invention, the retaining structure comprises a latching element connected to the frame body of the vehicle. In an embodiment of the invention, the latching element is adapted to receive at least one counter latching element and retain the at least one storage compartment in a latched state. In an embodiment of the invention, the battery retraining structure further comprises an actuating member acting upon the latching element and being adapted to, upon actuation, permit the at least one storage compartment to reach an un-latched state with respect to the latching element. The battery retaining structure further comprises at least one movement restricting mechanism connected to the frame body. The at least one movement restricting mechanism inhibits movement of the at least one battery when the at least one storage compartment is in the latched state.

[014] In an embodiment of the invention, the frame body comprises a head pipe; an upper frame extending from the head pipe in a rearward direction; a first seat frame extending from the upper frame in a rearward direction and being disposed on a first side of the upper frame; a second seat frame extending from the upper frame in a rearward direction and being disposed on a second side of the upper frame. In an embodiment of the invention, the first seat frame and the second seat frame support the at least one seat. The frame body further comprises a first lower frame extending from one of the head pipe and the upper frame in a downward and rearward direction. The frame body further comprises a first pivot frame and a second pivot frame, both the first pivot frame and the second pivot frame extend from the upper frame in the rearward and downward direction. The first pivot frame and the second pivot frame are spaced apart from each other in a vehicle width direction.

[015] In an embodiment of the invention, the upper frame comprising the latching element, and the at least one movement restricting mechanism.

[016] In another embodiment of the invention, the at least one storage compartment is pivotally connected to the frame body and exhibits pivotal movement with respect to the frame body to attain the latched state and the un-latched state.

[017] In yet another embodiment of the invention, the at least one counter latching element forms part of the at least one movement restricting mechanism.

[018] In still another embodiment of the invention, the at least one counter latching element forms part of the at least one storage compartment.

[019] One of the advantages of the present invention is that, a combination of the storage compartment and the battery retaining structure are involved in inhibiting un-wanted movement of the battery. A first level of movement restriction is attained by the latching element which retains the storage compartment in a latched state and a second level of movement restriction is attained by the movement restricting mechanism. Thus, the battery is more securely held with respect to the frame body and un-wanted movement of the battery is effectively prohibited.

[020] Another advantage of the invention is that the movement restricting mechanism applies a positive pressure on the battery, which is generally not attained by the storage compartment itself or by any other vehicular component.

[021] Still another advantage of the invention is that the movement restricting mechanism does not hinder in any way in insertion or removal of the battery from the storage compartment.

[022] A further advantage of the invention is that there is a lot of flexibility in placement of the latching mechanism and the counter latching mechanism, for instance, the counter latching mechanism can be either forming part of the storage compartment or can be forming part of the movement restricting mechanism. Thus, placement of the latching mechanism as well as the counter latching mechanism can be modified to suit the space availability and to avoid hinderance with other vehicular components.

[023] The construction of the movement restricting mechanism is substantially simple. Thus, it is easy to manufacture the movement restricting mechanism. Also, the mechanism for joining the movement restricting mechanism to the frame body is simple. Thus, a cost and a time involved in joining the movement restricting mechanism to the frame body is substantially low.

[024] The first roller forming part of the movement restricting mechanism undergoes uniform wear and tear and hence can serve for longer period of time. Thus, the possibility of premature failure of the movement restricting mechanism is substantially low and also a cost of replacement of the first roller is substantially low.

[025] Since the battery is securely held, the possibility of un-wanted and sudden disruption of the electricity flow from the at least one battery to the at least one motor, especially during movement of the electrical vehicle is substantially prohibited. As un-intended disruption of the electricity flow from the at least one battery to the at least one motor can cause accidents, hamper user experience in driving; a level of safety as well as a vehicle driving experience is substantially improved.

[026] To further clarify the advantages and features of the invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope.

The terms “vehicle”, “two wheeled vehicle” and “motorcycle” have been interchangeably used throughout the description. The term “vehicle” comprises vehicles such as motorcycles, scooters, bicycles, mopeds, scooter type vehicles, All-Terrain Vehicles (ATV) and the like.

[059] Referring to Figure 1 and Figure 2, there is illustrated a first side view and a second side view of an electric vehicle (10). The electric vehicle (10) comprises, inter-alia, a frame body (12), a front fork (14), a front cowl (16), a front ground engaging member (18), a front fender (20), a headlight (22), a rear ground engaging member (24), a steering handle bar (26), a motor unit (28), a seat (30), a tail light (32), a rear cushion (34), a rear fender (36), a front mirror (38), a transmission unit (40). The vehicle (10) further comprises a first battery (42) disposed in the first side of the vehicle (10) and a second battery (44) disposed in the second side of the vehicle (10). In an embodiment of the invention the first battery (42) is accommodated within a first storage compartment (46) and the second battery (44) is accommodated within a second storage compartment (48).

[060] The It may be noted that the electric vehicle (10) may include other parts which may not be relevant for explaining the present invention and hence not shown and described. The motor unit (28) is supplied electrical power from at least one of the first battery (42) and the second battery (44). The motor unit (28) generates driving power and transfers the same to at least one of the front ground engaging member (18) and the rear ground engaging member (24). In the embodiment illustrated in Figure 1 and Figure 2, the motor unit (28) is shown as transferring the driving power to the rear ground engaging member (24) vide the transmission unit (40). It may however be noted that the motor unit may be mounted on the rear ground engaging member (24) or alternatively be mounted on the front ground engaging member (18).

[061] Now referring to Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, and Figure 8 in an embodiment of the invention, the first storage compartment (46) and the second storage compartment (48) are pivotally mounted on the frame body (12). The electrical vehicle (10) further comprises a latching element (102) (best seen in Figure 6, Figure 7, and Figure 8) whose function is to retain at least one of the first storage compartment (46) and the second storage compartment (48) in a latched state. The latching element (102) may be mounted on the frame body (12). The electrical vehicle (10) further comprises an actuating member (104) (best seen in Figure 6, Figure 7, Figure 11, Figure 13, and Figure 15) acting upon the latching element (102) and being adapted to, upon actuation, permit the first storage compartment (48) and/or the second storage compartment (48) to reach their respective un-latched state with respect to the latching element (102). It may be noted that as shown in Figure 6, Figure 7, and Figure 8, there may be provided a singular latching element (102) which functions to retain both the first storage compartment (46) and the second storage compartment (48) in a latched state. It may be noted that the actuating member (104) may act upon the singular latching element (102) such that it simultaneously permits both the first storage compartment (48) and/or the second storage compartment (48) to reach their respective un-latched state. In an alternative embodiment, the actuating member (104) may act upon the singular latching element (102) such that it only permits at a point of time one of the first storage compartment (48) and/or the second storage compartment (48) to reach its respective un-latched state and at a different point in time permits the other of the first storage compartment (48) and/or the second storage compartment (48) to reach its respective un-latched state.

[062] Alternatively, although not illustrated, there may be provided two separate latching elements which function to retain the first storage compartment (46) and the second storage compartment (48), respectively in a latched state. In case two separate latching elements are provided, there may also be provided two separate actuating members (not shown) which will act upon the two separate latching elements and permit the first storage compartment (48) and the second storage compartment (48) to reach their respective un-latched state with respect to the latching element (102).

[063] Now referring to Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, and Figure 8, the frame body (12) further comprises a first movement restricting mechanism (106) adapted to inhibit movement of the first battery (42) when the first storage compartment (46) is in the latched state. There may be additionally provided a second movement restricting mechanism (206) adapted to inhibit movement of the second battery (46) when the second storage compartment (48) is in the latched state.

[064] In particular, Figure 3 shows the first storage compartment (46) and the second compartment (48) being in a fully pivoted state with respect to the latching element (102). Now referring particularly to Figure 6, in the fully pivoted state of the first storage compartment (46), the first battery (42) can be inserted into as well removed from the first storage compartment (46). It may be noted that in the fully pivoted state of the first storage compartment (46), the first movement restricting mechanism (106) does not come in contact with the first battery (42) and therefore does not inhibit movement of the first battery (42) as shown in Figure 6.

[065] Although not shown, it may be noted that, in the fully pivoted state of the second storage compartment (48), the second battery (44) can be inserted into as well as removed from the second storage compartment (48). Likewise, in the fully pivoted state of the second storage compartment (48), the second movement restricting mechanism (206) does not come in contact with the second battery (44) and therefore does not inhibit movement of the second battery (44).

[066] Now referring particularly to Figure 5, there is illustrated the first storage compartment (46) and the second compartment (48) being in a latched state with respect to the latching element (102). Now particularly referring to Figure 8, in the latched state of the first storage compartment (46), the first battery (42) can neither be inserted into nor removed from the first storage compartment (46). Also, as can be seen in Figure 8, in the latched state of the first storage compartment (46), the first movement restricting mechanism (106) presses on a top surface of the first battery (42) and therefore inhibits movement of the first battery (42).

[067] As can be seen from Figure 8, in the latched state of the second storage compartment (48), the second battery (44) can neither be inserted into nor removed from the second storage compartment (48). Also, in the latched state of the second storage compartment (48), the second movement restricting mechanism (206) presses on a top surface of the second battery (44) and therefore inhibits movement of the second battery (44).

[068] Now referring particularly to Figure 4, there is illustrated a state which is attained between the fully pivoted state of the first storage compartment (46) and the latched state of the first storage compartment (46). It may be noted that even in the state illustrated in Figure 4, the first storage compartment (46) is not latched with respect to the latching element (102). Now particularly, referring to Figure 7, in this state, a lateral surface of the first battery (42) or a lateral surface of the first storage compartment (46) comes in abutting relation with the first movement restricting mechanism (106). In case a force is applied on the first storage compartment (46) towards the latched state as shown by the first arrow (120), the force is transferred to the first movement restricting mechanism (106), which causes the first movement restricting mechanism (106) to exhibit a pivotal movement as shown by the second arrow (122) and the third arrow (124). Thus, the top surface of the first battery (42) comes in abutting relationship with the first movement restricting mechanism (106). The pivotal movement of the first storage compartment (46) is permitted till the first storage compartment (46) comes to the latched state. Thus, the pivotal movement of the first movement restricting mechanism (106) is permitted only till the first storage compartment (46) comes to the latched state. Thereafter, pivotal movement cannot be exhibited by either the first storage compartment (46) or the first movement restricting mechanism (106).

[069] Likewise, Figure 4 illustrates a state which is attained between the fully pivoted state of the second storage compartment (48) and the latched state of the second storage compartment (48). It may be noted that even in the state illustrated in Figure 4, the second storage compartment (48) is not latched with respect to the latching element (102).

[070] Although not shown, in a manner similar to what has been shown in Figure 7, in this state, a lateral surface of the second battery (44) or a lateral surface of the second storage compartment (48) comes in abutting relation with the second movement restricting mechanism (206). In case a force is applied on the second storage compartment (48) towards the latched state, the force is transferred to the second movement restricting mechanism (206), which causes the second movement restricting mechanism (206) to exhibit a pivotal movement. Thus, the top surface of the second battery (44) comes in abutting relationship with the second movement restricting mechanism (206). The pivotal movement of the second storage compartment (46) is permitted till the second storage compartment (48) comes to the latched state. Thus, the pivotal movement of the second movement restricting mechanism (206) is permitted only till the second storage compartment (48) comes to the latched state. Thereafter, pivotal movement cannot be exhibited by either the second storage compartment (48) or the second movement restricting mechanism (206).

[071] Now referring particularly to Figure 5 and Figure 8, there is illustrated the first storage compartment (46) and the second compartment (48) being in a latched state with respect to the latching element (102). In the latched state of the first storage compartment (46), the first battery (42) can neither be inserted into nor removed from the first storage compartment (46). Likewise, in the latched state of the second storage compartment (48), the second battery (44) can neither be inserted into nor removed from the second storage compartment (48). It may be noted that in the latched state of the first storage compartment (46), the first movement restricting mechanism (106) presses on the top surface of the first battery (42) and therefore inhibits movement of the first battery (42). Likewise, in the latched state of the second storage compartment (48), the second movement restricting mechanism (206) presses on the top surface of the second battery (44) and therefore inhibits movement of the second battery (44). Especially, the first movement restricting mechanism (106) after exhibiting pivotal movement, presses on the top surface of the first battery (42) and therefore inhibits movement of the first battery (42) in a vehicular upward direction when the first storage compartment (46) is in the latched state. Likewise, the second movement restricting mechanism (206) after exhibiting pivotal movement, presses on the top surface of the second battery (44) and therefore inhibits movement of the second battery (44) in a vehicular upward direction when the second storage compartment (48) is in the latched state.

[072] While generally stated, the latching mechanism (102) is adapted to receive a first counter latching element (50) to retain the first storage compartment (46) in a latched state and latching mechanism (102) is adapted to receive a second counter latching element (52) to retain the second storage compartment (48) in a latched state. However, it may be noted that the first counter latching element (50) and the second counter latching element (52) can be provided in different forms.

[073] For instance, referring to Figure 9, the first counter latching element (50) can be provided on the first storage compartment (46). Although not separately shown, the second counter latching element (52) can be provided on the second storage compartment (48). In such a case, as shown in Figure 11, the latching mechanism (102) is adapted to receive the first counter latching element (50) forming part of the first storage compartment (46) and retains the first storage compartment (46) in a latched state. Similarly, the latching mechanism (102) is adapted to receive the second counter latching element (52) forming part of the second storage compartment (48) and retains the second storage compartment in a latched state.

[074] Now referring to Figure 10, generally speaking the movement restricting mechanism (106) comprises a first arm (108), a second arm (110) protruding from the first arm (108), and a bracket element (112) connecting the movement restricting mechanism (106) to the frame body (12) of the vehicle (10). In a preferred aspect of the invention, the second arm (110) protrudes substantially perpendicularly from the first arm (108). The first arm (108) and the second arm (110) (which may be integrated as a single piece) may be coupled to the bracket element (112) vide a pivot axis defining element (114). Thus, the first arm (108) and the second arm (110) exhibit pivotal movement with regard to the pivot axis defining element (114). As mentioned above, the movement restricting mechanism (106) exhibits pivoting movement especially between a first state and a second state.

[075] In particular, as shown in Figure 7, a lateral surface of the first battery (42) or a lateral surface of the first storage compartment (46) comes in abutting relation with the second arm (110) of the first movement restricting mechanism (106). In case a force is applied on the first storage compartment (46) towards the latched state as shown by the first arrow (120), the force is transferred to the second arm (110) of the first movement restricting mechanism (106), which exhibit pivotal movement as shown by the second arrow (122). This causes the first arm (108) of the first movement restricting mechanism (106) to exhibit pivotal movement as shown by the third arrow (124). Thus, the top surface of the first battery (42) comes in abutting relationship with the first arm (108) of the first movement restricting mechanism (106). The pivotal movement of the first storage compartment (46) is permitted till the first storage compartment (46) comes to the latched state. Thus, the pivotal movement of the first arm (108) of the first movement restricting mechanism (106) and the second arm (110) of the first movement restricting mechanism (106) is permitted only till the first storage compartment (46) comes to the latched state. Thereafter, pivotal movement cannot be exhibited by either the first storage compartment (46) or the first movement restricting mechanism (106).

[076] The movement restricting mechanism (106) as specifically shown in Figure 10 can be advantageously used along the storage compartment as shown in Figure 9 (i.e. where the storage compartment has the counter latching element). It can be further seen from Figure 10 that the movement restricting mechanism (106) comprises a first roller (116) provided on the first arm (108). The first roller (116) comes in contact with the top surface of the first battery (42) to inhibit movement of the first battery (42) in a vehicular upward direction when the movement restricting mechanism (106) is in the first state. The first roller (116) also rotates when the top surface of the first battery (42) comes in contact with the first roller (116) and before the first storage compartment (46) attains the latched state. Thus, a different surface of the first roller (116) comes in contact with the top surface of the first battery (42) and hence, experiences uniform wear and tear.

[077] The movement restricting mechanism (106) may further comprise a second roller (118) provided on the second arm (110). The second roller (118) comes in contact with either a lateral surface of the first storage compartment (46) or a lateral surface of the first battery (42) before the first storage compartment (46) attains the latched state. After coming in contact with the lateral surface of the first storage compartment (46) or the lateral surface of the first battery (42) and till the first storage compartment (46) attains the latched state, the second roller (118) may rotate. Thus, a different surface of the second roller (118) comes in contact with the lateral surface of the first storage compartment (46) or the lateral surface of the first battery (42) and hence, experiences uniform wear and tear.

[078] Since, the first roller (116) presses down the first battery (42) and inhibits movement of the first battery (42) in a vehicular upward direction when the first storage compartment (46) is in the latched state, the first roller (116) is made of resilient member. Thus, the first roller (116) undergoes a compression between a state when the first roller (116) comes in contact with the top surface of the first battery (42) and the first storage compartment attaining the latched state. Therefore, the first roller (116) applies a positive pressure on the top surface of the first battery (42). This aspect of the invention has an added advantage in that when the first latching mechanism (102) releases the first storage compartment (46), the pressure that was initially applied on the first roller (116) gets released and this helps in marginally moving the first storage compartment (46) to the state as shown in Figure 4 or Figure 7 (from the state shown in Figure 5 or Figure 8). This therefore assists in opening the bringing the first storage compartment (46) to the fully pivoted state as shown in Figure 3 or Figure 6. The same aspect is applicable in respect of the second removement restricting mechanism (206) which comes in contact with the second battery (44).

[079] When the first counter latching element (50) is provided on the first storage compartment (46) and likewise, the first counter latching element (52) is provided on the second storage compartment (48), the latching element (102) is provided on the main frame (12) such that the latching elements gets sandwiched between the first storage compartment (46) and the second storage compartment (48), as shown in Figure 8 and Figure 15 (which has been described in detail later).

[080] When the first counter latching element (50) is provided on the first storage compartment (46), or alternatively when the second counter latching element (52) is provided on the second storage compartment (48), the first movement restricting mechanism (106) as shown in Figure 10 (or the second movement restricting mechanism (206)) does not contain the first counter latching element (50) (or the second counter latching element (52)). On the other hand, it may be noted that the latching mechanism (102) can act differently so as to latch the first storage compartment (46) and the second storage compartment (48). For instance, the first counter latching element (50) may form part of the first movement restricting mechanism (106) and the likewise, the second counter latching mechanism (52) may form part of the second movement restricting mechanism (206). This aspect of the invention is illustrated in Figure 11, Figure 12, Figure 13, and Figure 14.

[081] Now specifically referring to Figure 11 and Figure 12 together, it can be observed that the first counter latching element (50) is formed on the first arm (108) of the first movement restricting mechanism (106). Although not shown, the second counter latching element (52) is similarly formed on the second movement restricting mechanism (206). Now referring particularly to Figure 12 and Figure 16, the location of the latching mechanism (102) is changed and placed above the first movement restricting mechanism (106) and the second movement restricting mechanism (206). Thus, both the first counter latching element (50) and the second counter latching element (52) gets latched by the latching mechanism (102).

[082] In an alternative embodiment of the invention, as specifically shown in Figure 13 and Figure 14, it can be observed that the first counter latching element (50) is formed on the second arm (110) of the first movement restricting mechanism (106). Although not shown, the second counter latching element (52) is similarly formed on the second movement restricting mechanism (206). Now referring particularly to Figure 8 and Figure 15, the latching mechanism (102) is placed between the first movement restricting mechanism (106) and the second movement restricting mechanism (206). Thus, the latching mechanism (102) is located between the first storage compartment (46) and the second storage compartment (48). Thus, both the first counter latching element (50) and the second counter latching element (52) gets latched by the latching mechanism (102).

[083] Now referring to Figure 15 and Figure 16, in an embodiment of the invention, the frame body (12) comprises a head pipe (54); an upper frame (56) extending from the head pipe (54) in a rearward direction; a first seat frame (58) extending from the upper frame (56) in a rearward direction and being disposed on a first side of the upper frame (56); a second seat frame (60) extending from the upper frame (56) in a rearward direction and being disposed on a second side of the upper frame (56). The first seat frame (58) and the second seat frame (60) are spaced apart from one another and support the at least one seat (30).

[084] The frame body (12) further comprises at least a first lower frame (62) extending from one of the head pipe (54) and the upper frame (56) in a downward and rearward direction. The frame body (12) may optionally comprise a second lower frame (noy shown). In case the body frame (12) comprises the second lower frame, the spaced apart from the first lower frame (38) in a vehicle width direction.

[085] The frame body (12) further comprises a first pivot frame (64) extending from the upper frame (56) in the rearward and downward direction and connected with the first lower frame (32). The frame body further comprises a second pivot frame (66) extending from the upper frame (56) in the rearward and downward direction and connected with at least one of the first lower frame (62) or the second lower frame (in case the second lower frame is present).

[086] While in Figure 15 and Figure 16, the upper frame (56) does not depict the first movement restricting mechanism (106), and the second movement restricting movement (206); it may be noted that the upper frame (30) comprises the first movement restricting mechanism (106) and the second movement restricting mechanism (206).

[087] Now referring particularly to Figure 15, in one embodiment of the invention, the latching element (102) is positioned on the upper frame such that it protrudes in a vehicle downward direction or in a vehicle upward direction. Also, the latching element (102) in this condition gets sandwiched between the first storage compartment (46) and the second storage compartment (48).

[088] Now referring to Figure 16, in an alternative embodiment of the invention, the latching element is provided on the upper frame such that it protrudes in a vehicle width direction. Thus, the latching element (102) gets located above both the first movement restricting mechanism (106) and the second movement restricting mechanism (206).

[089] One of the advantages of the present invention is that, a combination of the storage compartment (46, 48) and the battery retaining structure (100) are involved in inhibiting un-wanted movement of the battery (42, 44). A first level of movement restriction is attained by the latching element (102) which retains the storage compartment (46, 48) in a latched state and a second level of movement restriction is attained by the movement restricting mechanism (106, 206). Thus, the battery (42, 44) is more securely held with respect to the frame body (12) and un-wanted movement of the battery (42, 44) is effectively prohibited.

[090] Another advantage of the invention is that the movement restricting mechanism (106, 206) applies a positive pressure on the battery (42, 44), which is generally not attained by the storage compartment (46, 48) itself or by any other vehicular component.

[091] Still another advantage of the invention is that the movement restricting mechanism (106, 206) does not hinder in any way in insertion or removal of the battery (42, 44) from the storage compartment (46, 48).

[092] A further advantage of the invention is that there is a lot of flexibility in placement of the latching mechanism (102) and the counter latching mechanism (50, 52), for instance, the counter latching mechanism (50, 52) can be either forming part of the storage compartment (46, 48) or can be forming part of the movement restricting mechanism (106, 206). Thus, placement of the latching mechanism (102) as well as the counter latching mechanism (50, 52) can be modified to suit the space availability and to avoid hinderance with other vehicular components.

[093] The construction of the movement restricting mechanism (106, 206) is substantially simple. Thus, it is easy to manufacture the movement restricting mechanism (106, 206). Also, the method for joining the movement restricting mechanism (106, 206) to the frame body (102) is simple. For instance, the movement restricting mechanism (106, 206) can be welded to the frame body (12). Thus, a cost and a time involved in joining the movement restricting mechanism (106, 206) to the frame body (12) is substantially low.

[094] Similarly, the method for joining the latching element (102) to the frame body (102) is simple. For instance, the and likewise, the latching element (102) can be welded to the frame body (102). Thus, a cost and a time involved in joining the latching element (102) to the frame body (12) is substantially low.

[095] The first roller (116) forming part of the movement restricting mechanism (106, 206) undergoes uniform wear and tear and hence can serve for longer period of time. Thus, the possibility of premature failure of the movement restricting mechanism (106, 206) is substantially low and also a cost of replacement of the first roller (118) is substantially low.

[096] Since the battery (42, 44) is securely held, the possibility of un-wanted and sudden disruption of the electricity flow from the at least one battery (42, 44) to the at least one motor unit (28), especially during movement of the electrical vehicle (10) is substantially prohibited. As un-intended disruption of the electricity flow from the at least one battery (42, 44) to the at least one motor unit (28) can cause accidents and hamper user experience in driving; a level of safety as well as a vehicle driving experience is substantially improved.
