[0002] Nowadays, electric vehicles (such as electric cars, electric bicycles, electric motorcycles, electric scooters, electric balance bikes, etc.) are becoming more and more popular. Generally, batteries are provided on electric vehicles. To ensure the safety of the batteries, battery locks are generally provided to lock and protect the batteries.

[0003] As disclosed in the authorized publication number CN204625095U, a battery locking device for an electric motorcycle battery power supply is disclosed, which includes a battery bracket for placing a forklift battery and a locking mechanism. The battery bracket is correspondingly matched with the forklift vehicle body; the locking mechanism includes a locking hook, a locking pin and a first elastic member. The locking hook is installed on the bottom surface of the battery bracket and can rotate around the longitudinal axis; the first elastic member is connected to the battery bracket and acts on the locking hook to keep the locking hook in a tensioned state; the locking pin is movably arranged on the forklift vehicle body and is engaged with or separated from the locking hook. With the above structure, the utility model can not only firmly lock the battery bracket during the operation of the forklift, avoiding the accidental sliding out of the battery bracket, but also make full use of the narrow space between the bottom surface of the battery bracket and the forklift vehicle body to make the installation of the locking mechanism more convenient. However, it does not solve the problem of adapting to the sizes of various power supply batteries, nor does it solve the problem of fixing the battery while making the structure as simple as possible. For this reason, we propose a battery locking device for an electric motorcycle battery power supply. Content of the Utility Model
