Single hole fixed anti-rotation structure in the battery module

Abstract

The invention provides a single-hole fixed anti-rotation structure in a battery module, which includes two limiting snap rings and two connecting parts. On the outward end surface of the fixed snap ring at the exposed end of the positive terminal and the total negative terminal, and the end face where the protrusion of the limit snap ring is located faces outward, the limit snap ring is parallel to the end fixed snap ring, and the two connections One end of the component is fixed together with the total positive terminal and the total negative terminal of the battery module respectively, and the other end of the connecting component passes through the two protrusions of the limit snap ring parallel to the end surface of the limit snap ring. and partially exposed. The single-hole fixed anti-rotation structure in the battery module of the present invention is simple and novel in design and easy to manufacture, and can prevent the battery pack and connecting parts corresponding to the total positive terminal and the total negative terminal of the battery module from rotating.

Description

technical field [0001] The invention relates to a single-hole fixed anti-rotation structure in a battery module. Background technique [0002] With the development of the new energy industry, batteries are used more and more widely, and people have higher and higher requirements for the safety performance of batteries. It is clearly stipulated that there should be no false connection at the battery connection. In severe cases, problems such as heat generation will greatly shorten the battery life, and even cause a fire. However, the extremely compressed space structure limits the structure of the positive and negative ends of the battery to a single hole, which cannot be modified. At present, the battery pack corresponding to the total positive terminal and the total negative terminal of the battery module is a single-hole fixed structure. The battery pack with this structure can be rotated in the terminal fixing snap ring, and its corresponding connecting parts It is easy...

[0002] With the development of the new energy industry, batteries are used more and more widely, and people have higher and higher requirements for the safety performance of batteries. It is clearly stipulated that there should be no false connection at the battery connection. Problems such as heat generation will greatly shorten the battery life and even cause a fire in severe cases.

However, the extremely compressed space structure limits the positive and negative poles of the battery to a single-hole structure, which cannot be modified.

At present, the battery pack corresponding to the total positive terminal and the total negative terminal of the battery module is a single-hole fixed structure. The battery pack with this structure can be rotated in the terminal fixing snap ring, and its corresponding connecting parts It is easy to rotate, and it is easy to cause the connection to be unstable, causing the input and output of the entire battery module to be unstable, and affecting the performance of the battery module
