Technical Field

[0001] This utility model belongs to the field of electric motorcycle technology, specifically a battery fixing and disassembly structure and an electric motorcycle. Background Technology

[0002] Electric motorcycles are a type of electric vehicle that uses batteries to power an electric motor. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. Other components of an electric motorcycle are basically the same as those of an internal combustion engine motorcycle.

[0003] The battery is the main power source of electric motorcycles. Existing electric motorcycles usually have a battery compartment on the frame, where the battery is placed. The battery compartment is then covered with a cover, which is fixed to the battery compartment with screws to secure the battery. However, when removing the battery, tools are needed to unscrew each screw one by one, and then the cover must be opened to remove the battery. This not only requires tools but is also time-consuming, laborious, and extremely inconvenient. Utility Model Content
