[0002] With the rapid development of new energy vehicles, charging piles can be seen everywhere. They can be fixed on the ground or wall to charge various models of new energy electric vehicles according to different voltage levels. When charging, the charging gun in the charging pile needs to be inserted into the charging socket on the surface of the electric vehicle.

[0003] After the existing charging gun is inserted into the charging socket, there is no protective mechanism at the connection between the charging gun and the charging socket, so that when it rains, rainwater from the outside can easily enter through the connection gap between the charging gun and the charging socket, thus posing certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: after the existing charging gun is inserted into the charging socket, there is no protective mechanism at the connection between the charging gun and the charging socket, which results in external rainwater easily entering through the connection gap between the charging gun and the charging socket when it rains, thus posing certain safety hazards. An electric vehicle charging pile with good protective performance is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electric vehicle charging pile with good protection performance comprises a gun body, a mounting plate is fixedly sleeved on the gun body, a corrugated tube is fixedly mounted on the surface of the mounting plate, a butt ring is fixedly sleeved on one end of the corrugated tube away from the mounting plate, a placement plate is symmetrically fixedly mounted on the side wall of the mounting plate, a telescopic spring is fixedly mounted on the surface of the placement plate, and one end of two telescopic springs away from the placement plate is fixedly connected to the surface of the butt ring;

[0007] A handle is fixedly mounted on the surface of the gun body, and vertical plates are symmetrically fixedly mounted on the surface of the handle. A rotating shaft is horizontally rotatably mounted between the two vertical plates, and an L-shaped positioning plate is fixedly sleeved on the rotating shaft. The positioning plate is connected to the two vertical plates through an elastic component.

[0008] Preferably, the elastic component includes two torsion springs sleeved on the rotating shaft, and two ends of the torsion springs are respectively fixedly connected to the positioning plate and the vertical plate.

[0009] Preferably, an annular airbag is provided on the surface of the butt ring away from the handle, and an air supply assembly is provided on the side wall of the mounting plate, and the air supply assembly is used to supply air into the annular airbag.

[0010] Preferably, the air supply assembly includes a hollow rod with a closed end, a piston rod with a sliding seal inserted in the hollow rod, and an air guide hose fixedly installed at the closed end of the hollow rod. The hollow rod is fixedly connected to the side wall of the mounting plate through a mounting component, and the end of the air guide hose away from the hollow rod is connected to the annular air bag, and the abutment ring surface is fixedly connected to one end of the piston rod through a U-shaped connecting rod.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 , an electric vehicle charging pile with good protection performance, comprising a gun body 1, a mounting plate 2 is fixedly sleeved on the gun body 1, a corrugated tube 3 is fixedly installed on the surface of the mounting plate 2, a ring 4 is fixedly sleeved on the end of the corrugated tube 3 away from the mounting plate 2, a placement plate is symmetrically fixedly installed on the side wall of the mounting plate 2, a telescopic spring 5 is fixedly installed on the surface of the placement plate, and the ends of the two telescopic springs 5 ​​away from the placement plate are fixedly connected to the surface of the ring 4, and a protective layer is bonded to the surface of the ring 4, and the material of the protective layer is rubber;

[0024] A handle 6 is fixedly mounted on the surface of the gun body 1, and a vertical plate 7 is symmetrically fixedly mounted on the surface of the handle 6. A rotating shaft is horizontally rotatably mounted between the two vertical plates 7, and an L-shaped positioning plate 8 is fixedly sleeved on the rotating shaft. The positioning plate 8 is connected to the two vertical plates 7 through an elastic component. The elastic component includes two torsion springs 9 sleeved on the rotating shaft, and the two ends of the torsion spring 9 are respectively fixedly connected to the positioning plate 8 and the vertical plate 7;

[0025] In the initial state, the positioning plate 8 will be in a horizontal state under the elastic potential energy of the torsion spring 9, and its surface will be against the surface of the ring 4, thereby limiting the movement of the ring 4. When the gun body 1 needs to be used, the end of the gun body 1 is first inserted into the charging socket of the car, and then the positioning plate 8 is rotated so that the positioning plate 8 is no longer against the ring 4. After the restriction on the ring 4 is released, the ring 4 will move rapidly under the elastic potential energy of the multiple telescopic springs 5, and the bellows 3 will be stretched at this time until the ring 4 moves to against the surface of the car. At this time, the bellows 3 will cover the connection between the gun body 1 and the socket, which can play a protective effect and prevent external rainwater from entering through the connection gap between the gun body 1 and the socket;

[0026] When charging is completed, the gun body 1 is pulled out from the socket, and then the ring 4 is controlled to move toward the mounting plate 2 to shrink the bellows 3 and the two telescopic springs 5, and then the positioning plate 8 is controlled to rotate to achieve the restricted movement of the ring 4.

[0027] An annular air bag 10 is provided on the surface of the ring 4 away from the handle 6, and an air supply assembly is provided on the side wall of the mounting plate 2. The air supply assembly is used to supply air into the annular air bag 10. The air supply assembly includes a hollow rod 11 with a closed end, a piston rod 12 inserted in the hollow rod 11 with a sliding seal, and an air guide hose 13 fixedly installed at the closed end of the hollow rod 11. The hollow rod 11 is fixedly connected to the side wall of the mounting plate 2 through a mounting component. The mounting component includes two fixing plates 15 symmetrically fixedly installed on the side wall of the mounting plate 2, and one end of the two fixing plates 15 is fixedly connected to the surface of the hollow rod 11. One end of the air guide hose 13 away from the hollow rod 11 is connected to the annular air bag 10, and the surface of the ring 4 is fixedly connected to one end of the piston rod 12 through a U-shaped connecting rod 14;

[0028] When the end of the gun body 1 is inserted into the charging socket of the car and the restriction of the positioning plate 8 on the ring 4 is released, the ring 4 will move rapidly under the elastic potential energy of the multiple telescopic springs 5, and the bellows 3 will be stretched at this time until the annular airbag 10 on the surface of the ring 4 is in contact with the surface of the car. At this time, the bellows 3 will cover the connection between the gun body 1 and the socket, and in this process, the ring 4 will move with the piston rod 12 in the hollow rod 11. The volume of the hollow rod 11 becomes smaller and the pressure increases. The gas in the hollow rod 11 will enter the annular airbag 10 from the air guide hose 13, causing the annular airbag 10 to expand and deform. The annular airbag 10 will fit completely with the surface of the car. Because the surface of the car will have some bends and curved surfaces, there may be gaps after the ring 4 is in contact with the surface of the car. The inflated annular airbag 10 can prevent external rainwater from entering from the gap between the contact surface of the ring 4 and the surface of the car, thereby further improving the protection effect.

[0029] In the utility model, in the initial state, the positioning plate 8 will be in a horizontal state under the elastic potential energy of the elastic component, and its surface will be against the surface of the ring 4, thereby limiting the movement of the ring 4. When the gun body 1 needs to be used, the end of the gun body 1 is first inserted into the charging socket of the car, and then the positioning plate 8 is rotated so that the positioning plate 8 no longer resists the ring 4. After the restriction on the ring 4 is released, the ring 4 will move rapidly under the elastic potential energy of the multiple telescopic springs 5, and the bellows 3 will be stretched at this time until the ring 4 moves to resist the surface of the car. At this time, the bellows 3 will cover the connection between the gun body 1 and the socket, which can play a protective effect and prevent external rainwater from entering through the connection gap between the gun body 1 and the socket.

[0030] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
