AI Technical Summary

Technical Problem

The existing chargers have poor sealing effect and are prone to failure in sealing when used in humid or aqueous environments. At the same time, the shell lacks effective protective devices, and the anti-corrosion effect is limited.

Method used

A charging box assembly with an outer protective cover is designed, and the seal is achieved by installing the outer protective cover outside the inner body and using a first sealing gasket, a second sealing gasket and a frame sealing gasket inside to ensure good sealing effect and easy reinstallation after removal.

Benefits of technology

Double protection is achieved, which improves the protection effect and sealing performance, ensuring that the sealing effect lasts and is convenient to install when used in humid environments. At the same time, the corrosion resistance is improved by using stainless steel cover.
