AI Technical Summary

Technical Problem

Existing vehicle chargers have poor waterproof sealing performance under high-pressure water jet spray, wading, extreme temperature difference and vibration environments, which poses a risk of water leakage, leading to electrolytic corrosion and contact failure, and cannot meet the diverse charging needs of new energy vehicles.

Method used

The charger adopts an interference fit between the silicone cap and the charging port, a sealed silicone wrapping of the control circuit board, and a movable dust plug design to achieve an IP68 dustproof and waterproof rating. The interference fit between the silicone cap and the charging cable and the sealing silicone wrapping enhance the sealing performance, and a movable dust plug is provided to seal unused charging ports.

Benefits of technology

Ensuring the charger's dust and water resistance in harsh environments ensures continuous charging of devices, enhances the user's travel experience, and improves the reliability and safety of the devices.
