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 frame structure of an electric vehicle in particular a frame structure restricting an upward movement of at least a first battery and a second battery.

BACKGROUND OF THE INVENTION:
[002] Electric Vehicles such as electric motorcycles or electric scooters comprise at least one battery and a power generating motor to operate the vehicle. The power generating motor generates necessary drive force based on the electric power supplied by the battery. Currently, various types of electric motorcycles exist in the market such as an electric motorcycle in which a replaceable battery is used, wherein as the charge within the battery gets depleted it is replaced with another charged battery. Alternatively, the electric motorcycle comprises a chargeable battery, which may be recharged using a charger when the charge gets depleted.

[003] It is essential to firmly hold the at least one battery with respect to the frame so that an electrical connection between the at least one battery and other electric / electronic components is secure and continuous. Since the at least one battery is generally accommodated in a casing, the casing in itself is shaped to firmly hold the at least one battery and more particularly, a lid member of the casing is used for restricting the at least battery’s movement in an upward direction.

[004] However, in most cases, the lid member of the casing does not sufficiently restrict the at least battery’s movement in an upward direction. Thus, there exists a need to provide sufficiently restrict the at least battery’s movement in an upward direction.

[005] Additionally, various other requirements are also needed to be met, for example, a construction of a mechanism which restricts the at least battery’s movement in an upward direction should be simple, the mechanism which restricts the at least battery’s movement in an upward direction should weigh less, the mechanism which restricts the at least battery’s movement in an upward direction should can be easily assembled as well as disassembled, the mechanism which restricts the at least battery’s movement in an upward direction should consume very less space, the mechanism which restricts the at least battery’s movement in an upward direction should not hamper with placement or functioning of other elements of the vehicle, etc. Thus, there exists a need to provide a solution to cater to this un-met demand.

In an embodiment of the invention, the second arm member (122) is coupled to the upper frame (108) and extends above the upper surface (118) of the upper frame (108). As best seen in Figure 5, the first lower frame (104), the first pivot frame (110) and the first arm member (120) extend along the first side (124) of the upper frame (108). As best seen in Figure 6, the second lower frame (106), the second pivot frame (112), and the second arm member (122) extends along the second side (126) of the upper frame (108).

[0058] Now referring particularly to Figure 5, it can be seen that the first arm member (120) in particular comprises a first portion (128) connected to the first side (124) of the upper frame (108) at a first location (130); a second portion (132) connected to the first side (124) of the upper frame (108) at a second location (134); and a first intermediate portion (136) located between the first portion (128) and the second portion (132). Now referring particularly to Figure 6, it can be seen that the second arm member (122) in particular comprises a third portion (138) connected to the second side (126) of the upper frame (108) at a third location (140); a fourth portion (142) connected to the second side (126) of the upper frame (108) at a fourth location (144); and a second intermediate portion (146) located between the third portion (138) and the fourth portion (142). The first intermediate portion (136) comprises a first mounting provision (148) and the second intermediate portion (146) comprises a second mounting provision (150). The retaining member (116) is coupled to at least one of the first mounting provision (148) and the second mounting provision (150). By connecting the retaining member (116) to the first arm member (120) and the second arm member (122), a height of the retaining member (116) from the ground can be increased. Thus, it becomes possible to accommodate a battery having battery having increased height, without increasing a dimension of the upper frame (108).

[0059] Now referring particularly to Figure 7, there is illustrated a perspective view of the retaining member (116) constructed in accordance with an embodiment of the invention. The retaining member (116) the retaining member (116) comprises an H-shaped retaining member (116). In particular, it can be seen that the H-shaped retaining member (116) comprises a first longitudinal portion (150), a second longitudinal portion (152) spaced apart from the first longitudinal portion (150), and a cross portion (154) connecting the first longitudinal portion (150) and the second longitudinal portion (152). In an embodiment of the invention, the first longitudinal portion (150) and the second longitudinal portion (154) comprise a first set of resilient members (156) adapted to come in contact with the at least first battery (22) and the second battery (24) (best seen in Figure 2). The resilient members (156) can dampen vibrations which may be transmitted to the retaining member (116). By way of a non-limiting example, a life of the retaining member (116) may be improved by providing the resilient members (156). In an embodiment of the invention, the cross member (154) comprising a set of connecting provisions (158) for coupling the retaining member (116) to at least one of the upper frame (108) (best seen in Figure 3 and Figure 4), the first arm member (118) and the second arm member (120) (best seen in Figure 5 and Figure 6).

[0060] An advantage of the invention comprises the retaining membersufficiently restricts the at least battery’s movement in the upward direction. In particular, the retaining membersufficiently restricts the movement of both the first battery and the second battery in the upward direction. Thus, a singular retaining member is sufficient to movement of both the first battery and the second battery in the upward direction.

[0061] Another advantage of the invention comprises the construction of the retaining member being simple. For instance, the retaining member which is a H-shaped retaining member is very easy to construct and can be made of a single piece.

[0062] Yet another advantage of the invention comprisesthe retaining member having very less weight. As compared to a lid member, which restricts movement of both the first battery and the second battery in the upward direction, the weight of the retaining member is substantially less.

[0063] Still another advantage of the invention comprisesthe ability to easily assemble as well as disassemble the retaining member. In fact the retaining member can be assembled in multiple ways, for instance being coupled to the upper frame, being coupled to the first arm member, being coupled to the second arm member, being coupled to both the first arm member and the second arm member.

[0064] A further advantage of the invention comprises the retaining memberconsuming very less space. A furthermore advantage of the invention comprises the retaining membernot hampering with either placement or functioning of other elements of the vehicle.

[0065] One or more (preferably, all of the above factors) also contribute to a decrease in a cost of manufacturing the vehicle.
