AI Technical Summary

Technical Problem

The existing battery casing lacks a buffer structure, which makes the battery cells prone to deformation and terminal breakage under external force, posing a safety hazard.

Method used

Design a battery casing comprising a bottom plate, a top plate, and side plate assemblies to form an elastic buffer space. The conductive post assembly adopts an elastic component, and the support mechanism is in close contact with the battery. Through elastic deformation, it absorbs impact force and enhances the stability of battery fixation and electrical connection.

Benefits of technology

It effectively absorbs external impact forces, reduces the risk of battery deformation and terminal damage, ensures stable operation of the battery under severe vibration or collision, extends service life and improves the reliability of electrical connections.
