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

FIELD OF THE INVENTION:
[001] The present invention relates to a battery accommodating structure of an electric vehicle accommodating a battery and a vehicle incorporating the same.

BACKGROUND OF THE INVENTION:
[002] A vehicle in particularly a two-wheeled electric vehicle runs on a power provided by a battery accommodated within at least one battery accommodating structure provided in the vehicle. Conventionally, the battery accommodating structure is mounted on a frame structure of the vehicle. The installation of the battery within the battery accommodating structure and removal of the battery from the battery accommodating structure requires lifting of the battery in a vertical direction of the vehicle that requires higher amount of effort. Since, the battery has to be lifted in the vertical direction for removal and installation, there is always a requirement of free space above the battery accommodating structure and sides of the frame structure.

[003] To address above issues, the battery accommodating structure can be pivoted with respect to the frame structure which allows easy installation and removal of batteries. Such an arrangement of the battery accommodating structure has been disclosed in the Patent Number IN-408583B, wherein the pivot axis is provided near an outer edge of a bottom wall of the battery accommodating structure. In this arrangement since the battery tilts when the battery accommodation structure exhibits pivotal movement, the total height of lifting battery during installation or removal of battery from battery accommodation structure decreases, thereby reducing the effort. However, in this arrangement also there is a requirement of a free space over the battery accommodating structure to allow pivotal movement of the battery accommodating structure in an unhindered manner. Thus, the possibility of mounting any vehicular component above the battery accommodating structure is negligible in this case, which results in an inefficient utilization of the vehicle's available space impacting vehicle design flexibility and weight distribution.

[004] Thus, there is a requirement of providing a solution to one or more than one of aforementioned problems.

[0040] Referring to Figure 1andFigure 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 structure (12) supporting a front fork (14), a front ground engaging member (16), a front fender (18), a headlight (20), a rear ground engaging member (22), a steering handle bar (24), a motor unit (26), a seat (28),a tail light (30), a rear cushion (32), a rear fender (34),a front mirror (36),a transmission unit (38). The vehicle (10) further comprises a first battery (40) disposed in the first side of the vehicle (10) and a second battery (42) disposed in the second side of the vehicle (10).

[0041] 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.

[0042] Referring to Figure 3 and Figure 4, there is illustrated the frame structure (12) of the vehicle (10) when viewed from the first side and the second side respectively. The frame structure comprises a head pipe (44), an upper frame member (46) extending from the head pipe (44) in a rearward direction, a lower frame member (48) extending from one of the upper frame (46) and head pipe (44) in a downward-rearward direction and in a substantially rearward direction thereafter.

[0043] The frame structure (12) further comprises a first pivot frame member (50) and a second pivot frame member (52) extending from the upper frame member (46) in the rearward-downward direction and connected with the lower frame member (48).Further, a first battery accommodating structure (100) is disposed on a first side of the upper frame (48) and a second battery accommodating structure (200) is disposed in a second side of the upper frame (48).

[0044] In an embodiment of the invention, the battery accommodating structure (100) accommodating at least one battery(40). More particularly, the first battery accommodating structure (100) accommodates the first battery (40) and the second battery accommodating structure (200) accommodates the second battery (42).

[0045] Now referring to Figure 5 and Figure 6, the first battery accommodating structure (100) comprisesa first bottom wall (102) comprising a first innermost point (103) and first outermost point (105), and at least one first peripheral wall (108) extending from the first bottom wall (102). In an embodiment of the invention the first innermost point (103)is proximate to the frame structure (12).

[0046] In an embodiment of the invention, the first battery accommodating structure (100)is adaptable to be pivotably coupled to a first part of the frame structure (12) along a first pivot axis (541) parallel to the vehicle (10) rear front direction such that the first battery accommodating structure (100) performs a pivotal movement with respect to the frame structure (12) in a width direction. In an embodiment of the invention, the first pivot axis (541) being provided at the first innermost point (103).

[0047] Further, the first bottom wall (102) defines a first edge (104) and a second edge (106) parallel to vehicle (10) rear front direction. In an embodiment of the invention the first edge (104) is closer to the frame structure (12) and the first pivot axis (541) is provided at the first edge (104).

[0048] Since, the first battery accommodating structure (100) performs a pivotal movement with respect to the frame structure (12) along the first pivot axis (541), which is provide at innermost point (103). A space above the first battery accommodating structure (100) remains unaffected during the pivotal movement of the first accommodating structure (100). Thus, the space above the first battery accommodating structure (100) can be used to mount another vehicular component.

[0049] Again,referring to Figure 6, the first battery accommodating structure (100) is adaptable to come to a first state from a second state with respect to a latching mechanism (56)mounted on a predetermined portion of the frame structure (12). In an embodiment of the invention, the first state corresponding to a latched state of the battery accommodating structure (100) with respect to the latching mechanism (56)and the second state corresponding to unlatched stateof the battery accommodating structure (100) with respect to thelatching mechanism (56). The first battery accommodating structure (100) is restricted to exhibit pivotal movement with respect to the frame structure (12) in the latched state and while the first battery accommodating structure (100) is allowed to exhibit pivotal movement with respect to the frame structure (12) in the unlatched state.

[0050] Referring to Figure 7, a part of the at least one first peripheral wall (108) facing the frame structure (12) comprises a latching element (110). The latching element (110) is adaptable to come in a locked state with respect to the latching mechanism (56) thereby restraining the first battery accommodating structure (100) in the latched state. Further, the latching element (110), upon actuation of the latching mechanism (56) come in an unlocked state with respect to the latching mechanism (56) thereby allowing the battery accommodating structure (100) to return to the unlatched state permitting removal of the first battery (40).

[0051] Due to the locking of the latching element (110) with the latching mechanism (56) secure the first battery accommodating structure (100) remains in the latched state with enhanced stability. The enhanced stability of the first battery accommodating structure (100) in turns adds up in stability of the first battery (40) during the movement of the vehicle (10).

[0052] Now coming to an aspect of the construction of the first battery accommodating structure (100), the first peripheral wall (108) comprisesa first side wall (112)extending from the first edge (104) of the bottom wall (102) and a second side wall (114) extending from the second edge (106) of the bottom wall (102). Further, a rear wall (116) extends from the bottom wall (102) and connects the first side wall (112) and the second side wall (114) from the rear side. Similarly, a front wall (118) extends from the bottom wall (102) and connects the first side wall (112) and the second side wall (114) from the front side.

[0053] In an embodiment of the invention, the latching element (110) extends from the first side wall (112). By way of non- restrictive example, the first side wall (112)and the bottom wall (102) may be formed as a single wall, and the second side wall (114), the rear wall (116) and the front wall (118) may be formed as a single wall.

[0054] Now coming to an aspect of mounting the first battery accommodating structure (100) with the first part of the frame structure (12). In an embodiment of the invention,at least a first connecting mechanism (120) is disposed at about the first edge (104) of the first battery accommodating structure (100).The first connecting mechanism (120) defines the first pivot axis (541).Further, the first connecting mechanism (120) is pivotally coupled to a second connecting mechanism (not shown) of the first part of the frame structure (12)to pivotally couple the first battery accommodating structure (100) to the frame structure (12). In an exemplary embodiment of the present invention, the first part may be a part of the lower frame member (48) of the frame structure (12).

[0055] Although, not shown, according to an embodiment of the invention, the first connecting mechanism (120) may comprises one bracket member comprising a first portion and a second portion extending substantially perpendicularly from the first portion. The first portion is connected to the first bottom wall (102) and the second portion is connected to a part of the at least one first peripheral wall (108) facing the frame structure (12). Further, at least one pivot defining aperture is sandwiched between the first portion and the second portion. In an embodiment the invention, the at least one pivot defining aperture overlaps with at least one pivot defining aperture of the second connecting mechanism.

[0056] Although, the first battery accommodating structure (100) and the second battery accommodating structure (200) are disposed on two other i.e. in the first side and the second side of the vehicle (10). However, the construction of both the first battery accommodating structure (100) and the second battery accommodating structure (200) is identical.Thus, the embodiments of the present invention have been explained only with respect to the first battery accommodating structure (100) in abovementioned paragraphs.

[0057] One advantage of the present invention is that, during the pivotal movement of the battery accommodating structure along a pivot axis at the innermost point of the bottom wall , space above the battery accommodating structure remains unaffected. Thus, the space above the battery accommodating structure can be utilized for positioning other vehicular component, which leads to an optimization of the vehicular space. Since, the battery accommodating structure is adaptable to perform a pivotal movement away from the frame structure (12) in vehicle (10) width direction. One advantage of the present invention includes an ease in replacement of the battery form the battery accommodating structure, bybringing the battery accommodating structure to second state.

[0058] Since, the battery accommodating structure can be brought to the second state only upon actuation of the latching mechanism. One advantage of the present invention includes making the battery replacement process less complex. Since, the connecting mechanismis provided in the battery accommodating structure itself. One advantage of the present invention is that the coupling of the battery accommodating structure requires lesser number of additional components in comparison to existing battery accommodating structures.

[0059] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.
