Description

Technical Field

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

[0002] The charging gun head is installed according to different models of charging piles and car charging interfaces. It can charge various models of electric vehicles according to different voltage levels. However, existing charging gun heads are prone to leakage during use, and they are also prone to loosening or falling off during use, which affects people's normal use.

[0003] A search revealed that Chinese utility model patent CN202122581751.5 discloses a shockproof charging gun head, comprising a charging gun head, a connecting frame mounted at one end of the charging gun head with a hanging buckle welded to its outer wall, a rubber grip fitted on the outer wall of the charging gun head, and a connector mounted at the other end of the charging gun head. The connector has a first rotating shaft on its outer wall, with a sealing cover mounted on the outer wall of the first rotating shaft. A silicone insulating pad is fitted to the inner wall of the connector, and an installation groove is formed on the inner wall 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 thus improving the safety of the charging gun head.

[0004] For example, Chinese utility model patent application number CN202322695449.1 discloses an anti-electric shock electric vehicle charging gun, including a charging gun; a cable, which is fixedly connected to the bottom end of the charging gun; a handle, which is set at the upper end of the charging gun; a fixing ring, which is fixedly sleeved on the outer surface of the charging gun; an adsorption component, which is fixedly connected to the outer surface of the fixing ring; and a waterproof component, which is fixedly connected to the inside of the fixing ring. In the above solution, the charging gun, cable, handle, fixing ring, adsorption component, and waterproof component are designed to prevent rainwater from seeping into the charging interface and causing short circuits or electric shocks when using the charging gun to charge an electric vehicle in rainy or snowy weather. The guide post also presses into the sleeve shell to fix the charging gun relatively to the electric vehicle during charging, preventing it from falling off and causing an electric shock. The storage component allows for convenient storage of the cable connected to the charging gun, preventing it from getting tangled with the car or people.

[0005] While the existing charging guns can meet basic usage requirements, they lack corresponding anti-electric shock structures before being inserted into the charging station. External objects can easily enter the charging gun, causing electric shock, and leakage cannot be avoided. This is especially true for charging stations that use AC power, where leakage can lead to serious safety accidents. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a three-safety-door anti-electric shock structure for a charging gun, which addresses the above-mentioned defects of the prior art. This structure is achieved by providing an anti-electric shock sleeve on the charging plug, and rotating on the anti-electric shock sleeve to install a first safety door, a second safety door, and a third safety door arranged in a triangular pattern with their vertices distributed sequentially. When the charging port is inserted, the safety doors change from a vertical state to a horizontal state. After the charging port is removed, the safety doors return to their original positions under the action of a spring. This prevents external objects from touching the inside of the charging gun plug when it is not in use, thus achieving the effect of preventing electric shock and avoiding safety accidents.

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

[0008] A three-safety-door anti-electric shock structure for a charging gun includes a charging gun plug, with a plurality of charging pins inside the charging gun plug. An anti-electric shock sleeve is fitted over the outer side of the end of each charging pin. A plurality of safety doors are rotatably mounted on the anti-electric shock sleeve, with the ends of the safety doors extending out of the anti-electric shock sleeve. Each safety door includes a first safety door, a second safety door, and a third safety door arranged in a triangular shape with their vertices arranged sequentially. Each of the first, second, and third safety doors is fitted with a spring, which abuts against the inner side of the safety door and the anti-electric shock sleeve, respectively.

[0009] Preferably, the inner side of the anti-electric shock jacket is provided with a plurality of safety door mounting grooves arranged in a triangular pattern with the vertices of the grooves distributed sequentially, and the first safety door, the second safety door and the third safety door are all installed sequentially on the safety door mounting grooves.

[0010] Preferably, the first safety door, the second safety door, and the third safety door each include a toggle post, a safety door baffle, and a rotating post, wherein the rotating post is integrally connected to the toggle post and the safety door baffle, respectively.

[0011] Preferably, the outer side of the anti-electric shock jacket is provided with a through hole for the actuating post to pass through, and the end of the actuating post passes through the through hole.

[0012] Preferably, one side of the anti-electric shock jacket is fitted onto the outside of the charging plug, 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] By adopting the above technical solution, the present invention provides a three-safety-door anti-electric shock structure for a charging gun, which has the following beneficial effects: The charging gun plug in the three-safety-door anti-electric shock structure has several charging pins inside. An anti-electric shock sleeve is fitted over the outer end of each charging pin. Several safety doors are rotatably mounted on the anti-electric shock sleeve, with the ends of the safety doors extending beyond the sleeve. Each safety door includes a first safety door, a second safety door, and a third safety door arranged in a triangular pattern with their vertices sequentially distributed. The first safety door, the second safety door, and the third safety door... Each component is fitted with a spring, which abuts against the inner side of the safety door and the anti-electric shock sleeve. The anti-electric shock sleeve is installed on the charging plug, and a first safety door, a second safety door, and a third safety door with their vertices arranged in a triangle are rotatably installed on the anti-electric shock sleeve. When the car charging interface is inserted, the safety door changes from a vertical state to a horizontal state. After the car charging interface is pulled out, it can return to its original position under the action of the spring. This prevents external objects from touching the inner side of the charging gun plug when it is not in use, thus achieving the effect of preventing electric shock and avoiding leakage that could lead to a safety accident.

[0023] like Figure 1-3 As shown, the charging gun's three-safety-door anti-electric shock structure includes a charging gun plug with several charging pins inside. An anti-electric shock sleeve is fitted over the outer end of each charging pin, and several safety doors are rotatably mounted on the sleeve. The ends of these safety doors protrude beyond the sleeve. Each safety door includes a first safety door, a second safety door, and a third safety door, arranged in a triangular shape with their vertices sequentially distributed. Springs are fitted onto each of the first, second, and third safety doors, and these springs abut against the inner sides of the safety doors and the anti-electric shock sleeve, respectively. It is understood that there are four charging pins 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 several safety door mounting grooves 8 arranged in a triangular shape with their vertices distributed sequentially. The first safety door 4, the second safety door 5, and the third safety door 6 are all installed sequentially on the safety door mounting grooves 8. The first safety door 4, the second safety door 5, and the third safety door 6 each include a toggle post 9, a safety door baffle 10, and a rotating post 11. The rotating post 11 is integrally connected to the toggle post 9 and the safety door baffle 10, respectively. The outer side of the anti-electric shock jacket 3 is provided with a toggle post through hole 12 for the toggle post 9 to pass through. The end of the toggle post 9 passes through the toggle post through hole 12.

It features an anti-electric shock sleeve 3 on the charging plug 2, and three safety doors 4, 5, and 6 arranged in a triangular pattern with their vertices sequentially distributed on the sleeve 3. When the charging port is inserted, the safety doors rotate 90 degrees under the pushing force of the charging port's outer shell, changing from a vertical to a horizontal position, allowing the charging connector to be inserted into the charging port's connection hole 13. After charging is complete, when the charging port is unplugged, the safety doors rotate 90 degrees back under the action of the spring 7, changing from a horizontal to a vertical position, thus returning to their original position. This prevents external objects from touching the inside of the charging gun plug when not in use, effectively preventing electric shock and avoiding leakage that could lead to safety accidents.
