Electric vehicles, as a type of new energy vehicle, have attracted widespread attention. In recent years, new energy vehicles have developed rapidly, and major automobile companies have also achieved certain research and development results and products. The fastest-growing and most currently in demand are pure electric vehicles and hybrid vehicles.

[0003] Therefore, the charging port structure of electric vehicles is an important structure in electric vehicles. Whether the charging port structure design is reasonable directly affects the normal use and safety of the charging port of electric vehicles. The charging port structure usually includes a charging port cover arranged at the mouth of the charging port, and a charging seat arranged on the body and opposite to the charging port; the charging interface is generally formed in one piece by an injection mold, but the shape of the charging interface is relatively complex, and glue leakage may occur during direct molding, especially at the connection point fixed with the vehicle, which is usually fixed with bolt holes. Rainwater can easily enter the charging port through the bolt holes, and conduct electricity with the screws to cause leakage, which affects the normal use of the charging seat and reduces the safety of the car charging process.

[0004] Therefore, it is necessary to develop a DC charging panel for new energy vehicles to solve the above problems. Utility Model Content
