[0053] The implementation principle of an electric motorcycle in an embodiment of the present application is as follows: the battery module 2 is located between the two frames 111, so that the two frames 111 respectively protect the left and right sides of the battery module 2, so that the impact from the left and right sides during the driving of the motorcycle is blocked by the two frames 111 respectively, so that the battery module 2 is not easily damaged. At the same time, one end of the two frames 111 is fixedly connected, and the other end of the two frames 111 is connected with a connecting shaft 112, so that the space between the two frames 111 is sufficient to accommodate the battery module 2 while also having a stable anti-collision structural strength, thereby further increasing the protection performance of the battery module 2 and improving the collision that is more likely to cause damage to the battery module 2 during the use of the electric motorcycle, generally a collision on the left and right sides of the frame 1, relying on the body cover to wrap and protect the left and right sides of the battery module 2, the protection effect of the battery module 2 is not good, which easily causes the battery module 2 to be affected by the collision and then damaged.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
