Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a double anti-falling battery box. Background Art

[0002] In the field of electric vehicles such as electric vehicles and electric bicycles, the stable installation and convenient disassembly of the battery box have always been important considerations in the design. The traditional battery box design often focuses on a single locking mechanism, such as a simple lock or screw fixing method. After unlocking, these designs often expose the battery box directly to the outside and lack the necessary secondary insurance measures, which may cause the battery box to fall, causing battery damage or even causing safety accidents.

[0003] To solve the above problems, the anti-fall function needs to be considered in the design, but the potential risk of direct collision between the anti-fall component and the tube frame, resulting in damage to the anti-fall component and loss of the anti-fall function, needs to be considered. Therefore, it is necessary to add an insurance mechanism on the basis of the anti-fall function. For example, the strength of the hand can be used as a buffer to reduce the collision force between the anti-fall buckle and the tube frame, thereby extending the service life of the anti-fall buckle and improving the safety and reliability of the entire battery box system.

[0004] Based on this, the applicant proposed a double anti-fall battery box to solve the above technical problems. Utility Model Content
