Description
Technical Field
[0001] The utility model relates to the technical field of charging piles, and in particular to a waterproof structure of a European standard charging conversion head. Background Art
[0002] Most new energy vehicles are powered by electricity. Once the battery is depleted, they are recharged via a charging station. This charging station uses a charging gun that plugs into the vehicle's charging port. Similar to gas pumps at gas stations, charging stations can be fixed to the ground or wall and installed in parking lots or charging stations in public buildings and residential communities. They can charge various models of electric vehicles at different voltage levels. The input end of the charging station uses a charging adapter that connects directly to the AC power grid, while the output end is equipped with a charging plug for charging electric vehicles. For example, the Chinese utility model patent with patent application number CN202222189557.7 discloses a charging head for converting from American standard to national standard, including a left shell, a right shell, a national standard conversion head, and an American standard conversion head. The American standard conversion head is provided at one end of the national standard conversion head, and a left shell is provided on one side of the American standard conversion head and the national standard conversion head. The right shell is provided on the other side of the American standard conversion head and the national standard conversion head. First clamping rings are provided at both ends of the left shell, and second clamping rings are provided at both ends of the right shell. The first clamping ring and the second clamping ring are enclosed. A first limiting ring is provided at one end of the national standard conversion head, and a second limiting ring is provided at one end of the American standard conversion head. The two first clamping rings and the second clamping rings are attached to one side of the first limiting ring and the second limiting ring and are clamped with them. The national standard conversion head and the American standard conversion head are combined to form a new device with the two interfaces. The American standard charging gun can charge the national standard charging port. The same car can be charged with different charging guns, bringing greater convenience to people. However, in the existing charging adapter, the barrel and the connector are installed with screws, and the shell is connected by a left shell and a right shell, which cannot be seamlessly connected and has low sealing. In addition, AC charging piles are generally installed outdoors, and electric vehicles, RVs, etc. need to be charged regardless of wind or rain, so this makes the waterproof requirements of the charging adapter relatively high.
