“AN ELECTRIC VEHICLE”

HERO MOTOCORP LIMITED, an Indian company, of The Grand Plaza, Plot No. 2, Nelson Mandela Road, Vasant Kunj- Phase-II, New Delhi – 110070, India,

The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[001] Present disclosure relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to an electric vehicle and more particularly, to a body frame of the vehicle.

BACKGROUND
[002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[003] Vehicles, particularly electric vehicles configured to be ridden such as motorcycles, etc., among other components and assemblies include a body frame, a power unit, a passenger seating area, a storage space, and a set of wheels. The power unit is adapted to provide necessary power to the wheels, to drive the vehicle. The power unit, seating area, storage space, etc., are all carried by the body frame. With that, the body frame is designed to carry substantial load of the vehicle, including weight of the power unit, other components, and sub-assemblies of the vehicle. In turn, the set of wheels being connected to the body frame, bears some of such weight being carried by the body frame and transfer to the ground.

[004] Conventionally, the electric vehicles may have one or more energy sources such as battery modules, which power the vehicle. In some vehicles, the energy sources are generally fixed to a battery tray of the vehicle and require effort and labor time to remove or replace such energy sources. In some vehicles, although the energy sources are removably mounted using fastening means, snap joints, and the like, process of removing such energy sources is time-consuming during charging or maintenance.

[005] Further, positioning two or more energy sources in a vehicle width direction may not be feasible, due to restrictions for the width-wise direction of the body frame. In view of such restrictions in conventional vehicles, the energy sources may be positioned along a vehicle length direction. However, such positioning along length direction may require an overhanging section in the battery tray, in order to removably accommodate the energy sources. Further, such conventional solution increases problems associated with addition of weight of the body frame. Thus, to cater to problems of the conventional battery module packaging in the vehicle, there is a need to modify the battery tray mounting relative to the body frame.

[006] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the body frame of the conventional vehicle.

SUMMARY
[007] The one or more shortcomings of the prior art are overcome by the system/assembly as claimed, and additional advantages are provided through the provision of the system/assembly/method as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.

[008] In one non-limiting embodiment of the present disclosure, an electric vehicle is disclosed. The electric vehicle comprises a body frame comprising a head tube, a down frame connected to the head tube and extending downwardly and rearwardly from the head tube, and a left seat rail and a right seat rail extending rearwardly and upwardly from a left end portion and a right end portion of the down frame. The electric vehicle further comprises a battery tray connected to a portion of the left seat rail and the right seat rail, and configured to receive and support at least one battery module. A support bracket is pivotally coupled to the body frame and extends rearwardly. Further, a first swing arm and a second swing arm are connected to the support bracket and configured to support the battery tray of the vehicle. At least one securing element comprises a first section and a second section. The first section is connectable to the battery tray and the second section is connected to the support bracket.

[009] In an embodiment of the present disclosure, the body frame comprises at least one pivot plate connected to the first swing arm and the second swing arm. At least one pivot plate is configured to secure the second section of the at least one securing element to the support bracket.

[010] In an embodiment of the present disclosure, the first section of the at least one securing element is at an angular position from the second section of the at least one securing element.

[011] In an embodiment of the present disclosure, the first swing arm is of a linear shape and extends rearwardly from the left seat rail of the body frame to the support bracket. The second swing arm is of a curved shape and extends rearwardly from the right seat rail of the body frame to the support bracket.

[012] In an embodiment of the present disclosure, the second swing arm comprises a first portion and a second portion. The first portion extends rearwardly substantially parallel to the first swing arm and the second portion extends in a vehicle width direction toward the support bracket.

[013] In an embodiment of the present disclosure, the first swing arm and the second swing arm are connected to the support bracket through a fastening means.

[014] In an embodiment of the present disclosure, the at least one pivot plate defines an aperture configured to secure the second section of the at least one securing element.

[015] In an embodiment of the present disclosure, the at least one securing element defines an angular shape and connectable to a lower portion of the battery tray.

[016] In an embodiment of the present disclosure, the battery tray is configured to position the at least one battery module in a longitudinal direction of the vehicle.

[017] In an embodiment of the present disclosure, the battery tray comprises at least one battery housing configured to secure the at least one battery module.
[018] The above-described configuration of the electric vehicle enables easy removal or replacing the battery modules secured in the battery tray. Further, the configuration provides a solution to a battery tray mounting on a body frame without compromising the stiffness of the body frame near a swing arm pivot area. The configuration also provides a support bracket which is integrated with the swing arm and a pivot plate; thus, three functions can be achieved with the help of a single component. This also reduces the number of parts used in the body frame and reduces the weight of the vehicle. The configuration further provides a solution to avoid a dimensional deviation failure in the vehicle. The above-described configuration provides strength to the securing element used to hold the battery tray because of the use of a dual sheet metal pivot plate. The provision of the at least one securing element connectable to the battery tray enables easy sliding of the battery tray to enable users to easily access the one or more battery modules.

[019] It is to be understood that the aspects and embodiments of the disclosure described above may be used in any combination with each other. Several of the aspects and embodiments may be combined together to form a further embodiment of the disclosure.

[020] The foregoing summary is illustrative only and is not intended to be in any way limiting.
