Description

Technical Field

[0002] Due to the rapid development of power lithium batteries, there have been considerable breakthroughs in production processes, material technology improvements, and price advantages. Therefore, it has also laid a solid foundation for multi-parallel and multi-series. The era of replacing lead-acid batteries is getting closer and closer. Whether it is electric bicycles or backup power supplies, its market share has naturally begun to expand wildly. This is an undeniable fact. For the safety and life of the battery, effective protection of the lithium battery is naturally indispensable. The protection board is one of the core components for protecting the lithium battery from over-current and over-discharge. It is difficult to provide all-round protection for the protection board in the existing technology.

[0003] The patent with announcement number CN222015477U discloses a protective lithium battery protection board, which includes a lithium battery protection board, and protective sleeves are inserted at the four corners of the lithium battery protection board. A cavity is arranged inside the protective sleeve, and a vertical spring and a transverse spring are fixedly installed on the inner wall of the cavity. Through the cooperation between the lithium battery protection board, the protective sleeve, air, the vertical spring, the transverse spring, the first elastic ball and the second spring ball, the two sides of the four corners of the lithium battery protection board can be wrapped and protected, which can better protect the lithium battery protection board when it is bumped. It is more comprehensive and prevents the lithium battery protection board from being damaged. Through the cooperation between the slot, the mounting plate, the bolts and the threaded holes, the protective cover can be conveniently inserted and fixedly installed at the four corners of the lithium battery protection board. The operation is simple and convenient for installation and disassembly. Although this patent solves the above problems, the protection board still needs to be fitted with the lithium battery. The front of the protection board is less affected by bumps, while the back of the protection board is more susceptible to bumps. It is difficult to protect the back of the protection board, so the protection board is still easily damaged. Therefore, a protective lithium battery protection board is proposed to solve the above problems. Summary of the invention
