Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to a two-safety-door anti-electric shock structure for a charging gun. Background Technology

[0002] Against the backdrop of a global push for a low-carbon economy, the focus of the automotive industry is shifting towards energy conservation and reducing greenhouse gas emissions, with the development of new energy vehicles becoming the mainstream trend. New energy vehicles are characterized by zero emissions, high energy efficiency, and low operating and maintenance costs. The promotion and popularization of electric vehicles can effectively alleviate the environmental pressure caused by human development. When charging the battery of a new energy vehicle, the charging gun is an essential accessory. Because the charging gun is directly connected to the vehicle's charging interface via a cable, the charging connector is always energized, posing a significant safety hazard.

[0003] A search revealed that Chinese utility model patent CN202320046255.6 discloses a waterproof charging gun. The waterproof charging gun includes a gun head, a contact structure, and a gun housing. The gun head has a first through hole; the contact structure passes through the first through hole and is equipped with a waterproof contact ring; a waterproof pad for the gun head is provided on the second end face of the gun housing, and a waterproof cable ring is provided on the first end of the gun housing. In this utility model, when liquid is present on the outer surface of the waterproof charging gun, it prevents liquid from entering the interior of the waterproof charging gun, ensuring the normal operation of the internal circuitry and reducing the risk of electric shock to workers. The contact structure, through an interference fit with the bending part, prevents rotation and axial displacement of the contact structure during operation, thus preventing poor contact. The cable fixing sleeve has an interference fit with the cable, preventing cable detachment and further reducing the risk of electric shock to workers.

[0004] For example, Chinese utility model patent application CN202122581751.5 discloses a shockproof charging gun head, including a charging gun head. One end of the charging gun head is fitted with a connecting frame, and the outer wall of the connecting frame is welded with a hanging buckle. A rubber grip is fitted onto the outer wall of the charging gun head, and the other end of the charging gun head is fitted with a connector. The outer wall of the connector is provided with a first rotating shaft, and the outer wall of the first rotating shaft is fitted with a sealing cover. A silicone insulating pad is attached to the inner side of the connector, and an installation groove is formed on the inner side of the connector. A conductive connector is connected to the inner side of the installation groove, and a placement groove is formed on the outer wall of the connector. This shockproof charging gun head, with its silicone insulating pad, provides excellent insulation and prevents leakage current during charging, avoiding accidents caused by leakage current and improving the safety of the charging gun head.

[0005] While the existing charging guns can meet basic usage requirements, their conductive sheets are all wrapped in insulating silicone. As the silicone ages, leakage and other issues cannot be avoided. This is especially true for charging guns that use AC power, where leakage can cause serious safety accidents. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a two-safety-door anti-electric shock structure for a charging gun, which addresses the above-mentioned defects of the prior art. By setting an anti-electric shock jacket on the charging column and installing an upper safety door and a lower safety door that are symmetrically arranged vertically on the anti-electric shock jacket, when the car charging interface is inserted, the upper safety door and the lower safety door change from a vertical state to a horizontal state. After the car charging interface is pulled out, they can return to their original positions under the action of springs, thereby preventing contact with the inner side of the charging gun body when not in use, achieving the effect of preventing electric shock and providing high safety.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A two-safety-door anti-electric shock structure for a charging gun includes a charging gun body. The inner side of the charging gun body is provided with a plurality of charging posts. An anti-electric shock jacket is fitted on the outer side of the charging posts. An upper safety door and a lower safety door are installed on the anti-electric shock jacket. The upper safety door and the lower safety door are symmetrically arranged on the anti-electric shock jacket. A spring is fitted on both the upper safety door and the lower safety door, and the spring abuts against the inner side of the anti-electric shock jacket.

[0009] Preferably, the inner side of the anti-electric shock jacket is provided with a safety door mounting groove, and both the upper safety door and the lower safety door are installed on the safety door mounting groove.

[0010] Preferably, both the upper and lower safety doors include a toggle post, a safety door baffle, and a rotating post, with the rotating post integrally connected to the toggle post and the safety door baffle, respectively.

[0011] Preferably, the upper and lower ends of the anti-electric shock jacket are provided with through holes for the actuating post to pass through, and the end of the actuating post passes through the through holes.

[0012] Preferably, one side of the anti-electric shock jacket is fitted over the outside of the charging post, and the other side of the anti-electric shock jacket has a charging interface connection hole.

[0013] Preferably, the spring is sleeved on the outside of the rotating column, the middle part of the spring abuts against the actuating column, and the end of the spring abuts against the anti-electric shock outer sleeve.

[0014] The present invention provides a two-safety-door anti-electric shock structure for a charging gun, which has the following advantages: An anti-electric shock jacket is fitted over the charging column of the two-safety-door anti-electric shock structure. An upper safety door and a lower safety door are installed on the anti-electric shock jacket, symmetrically arranged vertically. A spring is fitted onto each of the upper and lower safety doors, and the spring abuts against the inner side of the anti-electric shock jacket. By providing an anti-electric shock jacket on the charging column and ensuring safety, the structure achieves the desired effect. The charging gun housing is equipped with symmetrical upper and lower safety doors. When the car charging port is inserted, the upper end of the upper safety door and the bottom of the lower safety door are pushed backward by the car charging port. At this time, both the upper and lower safety doors change from a vertical state to a horizontal state. After the car charging port is pulled out, the doors can change from a horizontal state to a vertical state under the action of springs, thus returning to their original position. This prevents contact with the inside of the charging gun body when not in use, thus preventing electric shock and avoiding leakage that could lead to safety accidents. It is highly safe.

[0023] like Figure 1-3 As shown, the charging gun with a two-safety-door anti-electric shock structure includes a charging gun body 1. Several charging posts 2 are arranged on the inner side of the charging gun body 1. An anti-electric shock jacket 3 is fitted over the outer side of each charging post 2. An upper safety door 4 and a lower safety door 5 are installed on the anti-electric shock jacket 3, arranged symmetrically on the jacket. A spring 6 is fitted onto each of the upper and lower safety doors 4 and 5, and the spring 6 abuts against the inner side of the anti-electric shock jacket 3. It can be understood that there are four charging posts 2 arranged in a trapezoidal shape with their vertices sequentially distributed.

[0024] Specifically, the inner side of the anti-electric shock jacket 3 is provided with a safety door mounting groove 7, and the upper safety door 4 and the lower safety door 5 are both installed in the safety door mounting groove 7; the upper safety door 4 and the lower safety door 5 each include a toggle post 8, a safety door baffle 9 and a rotating post 10, and the rotating post 10 is integrally connected to the toggle post 8 and the safety door baffle 9 respectively; the upper and lower ends of the anti-electric shock jacket 3 are provided with toggle post through holes 11 for the toggle post 8 to pass through, and the end of the toggle post 8 is... The through hole 11 of the actuating post extends outward, and the width of the through hole 11 is greater than the height of the actuating post 10 so that the actuating post 10 has sufficient range of motion when it is actuated. One side of the anti-electric shock sleeve 3 is fitted onto the outside of the charging post 2, and the other side of the anti-electric shock sleeve 3 has a charging interface connection through hole 12. The spring 6 is fitted onto the outside of the rotating post 10, the middle part of the spring 6 abuts against the actuating post 8, and the end of the spring 6 abuts against the anti-electric shock sleeve 3.

By providing an anti-electric shock sleeve 3 on the charging column 2, and installing an upper safety door 4 and a lower safety door 5 symmetrically arranged on the anti-electric shock sleeve 3, when the car charging interface is inserted, the upper end of the upper safety door 4 and the bottom of the lower safety door 5 are pushed backward by the car charging interface. At this time, the upper safety door 4 and the lower safety door 5 change from a vertical state to a horizontal state, and the safety door baffle 9 also changes from a vertical state to a horizontal state. This allows the connector in the car charging interface to pass through the charging interface connection hole 12 and contact the connector in the charging gun body 1, thus realizing power supply. After the car charging interface is pulled out, the upper safety door 4 and the lower safety door 5 can change from a horizontal state to a vertical state under the action of the spring 6, thus completing the return to their original position. This prevents contact with the inside of the charging gun body when not in use, achieving the effect of preventing electric shock and avoiding leakage that could lead to safety accidents. It has high safety.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
