AI Technical Summary

Technical Problem

In existing battery cover assemblies, the pole posts have low torsional resistance, resulting in unstable connections and affecting the overall structural stability and reliability.

Method used

The design adopts a cover plate assembly, including a cover plate body, pole, upper plastic, lower plastic and positioning parts. The structural design of the rolled edge and anti-twist part restricts the movement and rotation of the pole. Combined with the fixed connection of the positioning parts, the connection reliability between the pole and the cover plate is improved.

Benefits of technology

This effectively prevents the pole from falling off, shifting, and rotating in the cover plate assembly, improves the pole's torsional and thrust resistance, and enhances the overall structural stability and reliability of the cover plate assembly.
