AI Technical Summary

Technical Problem

The top patch design of the existing battery top cover assembly results in exposed metal, which affects the battery's insulation performance and safety. In addition, there is an assembly gap between the explosion-proof valve protection plate and the terminal post, which also affects the insulation performance.

Method used

The design employs a combination of a shielding substrate layer and a transparent substrate layer. The transparent substrate layer covers the shielding substrate layer and is bonded together with a double-sided adhesive layer. The window size of the transparent substrate layer is smaller than that of the shielding substrate layer. Combined with the plastic derivative design, it covers the assembly gap between the pole post and the explosion-proof valve protection plate.

Benefits of technology

This effectively solves the problem of exposed metal, improves the battery's insulation performance, ensures the recognizability of the QR code and positive and negative markings, and avoids metal exposure caused by assembly gaps, further enhancing the battery's insulation performance.
