AI Technical Summary

Technical Problem

Existing new energy vehicle chargers lack waterproof structures, making them prone to water ingress in humid environments, which can lead to leakage and electric shock accidents. Furthermore, moisture intrusion can accelerate the oxidation of metal contacts, resulting in poor contact and reduced charging efficiency.

Method used

A charger with a multi-layer waterproof structure was designed, including a protruding waterproof structure and cover at the charging port, a three-layer gradient waterproof rubber ring at the front end of the charging gun, a protective sleeve at the connection between the charging gun and the power cord, and a detachable charging box to prevent moisture from entering.

Benefits of technology

It effectively prevents moisture from entering the charger, preventing short circuits and leakage accidents, ensuring charging efficiency and safety, and protecting the internal circuitry from moisture.

Abstract

This utility model discloses a new energy vehicle charger with a waterproof structure, including a charging box, an outer wall, a back frame, a first waterproof structure, a cover plate, a charging gun, a support base, and a second waterproof structure. The charging box has an outer wall on its outer side, a back frame on its back, and a first waterproof structure at the center of its front side. The center of the first waterproof structure is a charging port, and a cover plate is hinged to one side of the first waterproof structure. A charging gun is installed at the center of the charging port, a support base is located below the charging gun, and a second waterproof structure is located at the front end of the charging gun. This new energy vehicle charger with a waterproof structure forms a physical water barrier through the protruding design at the charging port, effectively preventing water from flowing directly in and avoiding the risk of short circuits caused by poor contact.
