, Description:FIELD OF THE DISCLOSURE
[001] The present disclosure is generally related to electric vehicle frame and more particularly to modular vehicle frame for mounting various sized transmission assembly components such as motor within the same vehicle frame.

BACKGROUND
[002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[003] Electric vehicles are powered by a motor drawing power from an onboard battery. Generally, motors are placed within frame of the electric vehicles and fixedly placed at one place. Also, the frame of the vehicles is generally built in such a manner so as to just house the motor snugly within so that there is no movement of the motor during the drive of the electric vehicle, that prevents any damage to the motor.
[004] However, often, vehicle manufacturers may want to change the motor for various reasons such as increasing/decreasing the motor capacity, change in the motor manufacturer and so on. Since, the frame, at which the motor is placed is designed so as to snugly place the motor within itself, when the motor size is changed, the frame used to mount the motor also has to be changed. This increases the overall manufacturing cost.
[005] In another scenario, motors from different manufacturers may also vary in size. This poses a problem during vehicle service when the motor has to be replaced as a spare motor has to be purchased from same manufacturer again and again in case of some faults.
[006] Therefore, there is a need to provide a solution a frame that could accommodate motors of varying sizes without changing any frame parts and with minimal effort.
