The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The utility model embodiment is an insulating and waterproof device for a charging pile charging interface, which includes a charging gun body 1, a movable movable frame 4 is provided on one side of the charging gun body 1 adjacent to the interface, and a fixed frame 3 is fixedly installed on the side away from the interface. A waterproof cloth 5 is connected between the fixed frame 3 and the movable frame 4, and the waterproof cloth 5 is covered on the outside of the charging gun body 1 to achieve a waterproof effect. Four elastic components 2 are equidistantly and symmetrically arranged between the movable frame 4 and the fixed frame 3 and on the outside of the waterproof cloth 5. The elastic component 2 enables the movable frame 4 to achieve repeatable and reciprocating horizontal movement on one side of the interface of the charging gun body 1; specifically, the movable frame 4 is supported by connecting the fixed frame 3 through the elastic component 2, and the waterproof cloth 5 is arranged between the movable frame 4 and the fixed frame 3 to protect the interface of the charging gun body 1 to prevent rainwater from entering the inside of the charging gun body 1 from the interface. And the movable frame 4 moves left and right. When the interface of the charging gun body 1 contacts the external socket, the connection can be sealed under the action of the movable frame 4 to prevent rainwater from entering the interface from the connection. At the same time, after the interface of the charging gun body 1 is separated from the external socket, the elastic component 2 can better push the movable frame 4 to move to the interface for protection. The overall structure is simple and easy to install. It can effectively prevent moisture from penetrating into the interface, improve the safety and reliability of the charging pile, and has practical value.

[0022] Reference Figure 1 , Figure 2 and Figure 3The elastic component 2 includes a slide bar 21 slidably connected to the inside of the fixed frame 3, a fixed plate 22 fixedly connected to the outside of the slide bar 21, a spring 23 sleeved on the outside of the slide bar 21 and located between the fixed plate 22 and the fixed frame 3, and a limit block 24 fixedly connected to one end of the slide bar 21 near the fixed frame 3. The other end of the slide bar 21 is fixedly connected to the movable frame 4. Specifically, the fixed plate 22 can move toward the side of the movable plate 4 under the action of the spring 23, so that the movable frame 4 can be located on one side of the interface to protect the charging gun body 1 through the waterproof cloth 5. After the interface of the charging gun body 1 is connected to the external socket, the movable frame 4 contacts the connection surface and can compress the spring 23 under the action of the movement of the charging gun body 1 so that the charging gun body 1 is normally connected to the external socket. After the charging gun body 1 is pulled out, the spring 23 can better push the movable frame 4 to move to the side of the interface, so that the charging gun body 1 can be protected under the action of the waterproof cloth 5.

When the charging gun body 1 is connected to the external socket, the sealing ring 6 can well seal the connection between the charging gun body 1 and the external socket. The sealing ring 6 is made of silicone rubber, and the sealing ring 6 made of silicone rubber has good sealing and insulation properties, thereby preventing impurities such as rainwater and dust from entering the interface of the charging gun body 1 through the connection between the charging gun body 1 and the external socket, which is conducive to its cleaning and drying.

[0024] An insulating coating is provided on the surface of the waterproof cloth 5 on the side close to the charging gun body 1. The insulating coating is a polyurethane coating. The insulating coating can effectively isolate the power supply and the external environment, and improve the insulation performance of the charging gun body 1. The fixed frame 3 and the movable frame 4 are both made of epoxy resin boards. The fixed frame 3 and the movable frame made of epoxy resin boards also have good insulation properties, which can play the role of electrical insulation support and ensure charging safety.

[0025] Working principle: The movable frame 4 is connected to the fixed frame 3 through the slide bar 21 to be supported. A waterproof cloth 5 is set between the movable frame 4 and the fixed frame 3 to protect the interface of the charging gun body 1 to prevent rainwater from entering the inside of the charging gun body 1 from the interface. The movable frame 4 moves left and right. When the interface of the charging gun body 1 contacts the external socket, the connection can be sealed under the action of the movable frame 4 to prevent rainwater from entering the interface. At the same time, after the interface of the charging gun body 1 is separated from the external socket, the spring 23 can better push the movable frame 4 to move to one side of the interface, so that the charging gun body 1 can be protected under the action of the waterproof cloth 5. The overall structure is simple and easy to install. It can effectively prevent moisture from penetrating into the interface, improve the safety and reliability of the charging pile, and has practical value.
