This invention addresses the design requirements of existing European standard charging guns by providing a charging gun that prevents users from directly contacting the charging terminals, thus protecting user safety. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a charging gun with anti-electric shock function.

[0004] To achieve the above objectives, this utility model discloses a charging gun with anti-electric shock function, including a housing body, a connector, a charging terminal, and a protective structure. The connector is located at the end of the housing body and includes a mounting compartment, a plug compartment, and a partition separating the mounting compartment and the plug compartment. The partition is provided with a clearance hole. The charging terminal is located in the mounting compartment, and the free end of the charging terminal extends into the plug compartment through the clearance hole.

[0005] The partition is provided with an installation cylinder located inside the plug-in compartment. The installation cylinder is sleeved outside the charging terminal, and the protective structure is provided on the installation cylinder.

[0006] The protective structure includes a flip block and a reset component. The flip block is rotatably connected to the mounting cylinder. The two ends of the flip block are a driven part and a blocking part, respectively. The driven part is located outside the mounting cylinder, and the blocking part is located inside the mounting cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model's charging gun features a protective structure, including a flip-up stop and a reset component. The flip-up stop is rotatably connected to the mounting cylinder. The flip-up stop has a driven part and a blocking part at its two ends. The driven part is located outside the mounting cylinder, and the blocking part is located inside. One end of the reset component abuts against the flip-up stop, and the other end abuts against the mounting cylinder. Under normal conditions, the blocking part rotates to close the mounting cylinder, preventing the user's fingers from directly touching the charging gun's charging terminals, thus ensuring user safety. When charging a car, the charging gun is plugged into the socket.

At this point, the mounting cylinder is fully open, and the charging gun's charging terminals align with the charging socket's charging terminals, enabling car charging.

[0017] The protective structure opens or closes the mounting cylinder using a flip-up stop and a reset component, resulting in a simple overall structure. Since it only requires adding a mounting cylinder to the partition of a traditional charging gun and installing the protective structure on the mounting cylinder, no other structural adjustments to the traditional charging gun are necessary. Therefore, the protective structure of this invention is suitable for traditional charging guns, offering high adaptability and reducing costs.

[0018] Existing charging guns have space between the charging terminals. This utility model has a mounting cylinder that is sleeved on the partition plate outside the charging terminals, which will not cause the size of the charging gun to increase. Therefore, it can be used in traditional charging guns and has high adaptability. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A charging gun with anti-electric shock function, see Figures 1-5 The device includes a main body 1, a connector 2, a charging terminal 3, and a protective structure 4. The connector 2 is located at the end of the main body 1 and includes a mounting compartment 21, a connector compartment 22, and a partition 23 separating the mounting compartment 21 and the connector compartment 22. The mounting compartment 21 is connected to a wiring channel 11 inside the main body 1. The partition 23 has a clearance hole 231. The charging terminal 3 is located inside the mounting compartment 21, and the free end of the charging terminal 3 extends into the connector compartment 22 through the clearance hole 231. During charging, the connector 2 is inserted into the charging base 5, and the charging gun and the charging terminal 3 of the charging base 5 are connected to perform charging.

[0031] In this embodiment, a mounting cylinder 24 located within the insertion compartment 22 is provided on the partition 23. The mounting cylinder 24 is sleeved over the charging terminal 3, and a protective structure 4 is provided on the mounting cylinder 24. The protective structure 4 includes a flip-up stop block 41 and a reset member 42. The flip-up stop block 41 is rotatably connected to the mounting cylinder 24. The two ends of the flip-up stop block 41 are a driven part 411 and a blocking part 412, respectively. The driven part 411 is located outside the mounting cylinder 24, and the blocking part 412 is located inside the mounting cylinder 24. One end of the reset member 42 abuts against the flip-up stop block 41, and the other end abuts against the mounting cylinder 24. Under normal conditions, under the action of the reset member 42, the blocking part 412 can rotate to close the mounting cylinder 24, thus preventing the user's fingers from directly touching the charging terminal 3 of the charging gun, ensuring user safety. When charging a car, the charging gun is plugged into the socket. When the edge of the socket of the charging base 5 presses against the driven part 411 of the flip stop block 41, the flip stop block 41 rotates until the blocking part 412 is in the open state. At this time, the mounting cylinder 24 is fully opened, and the charging terminal 3 of the charging gun is connected to the charging terminal 3 of the charging base 5, thus enabling the car to be charged. The protective structure 4 specifically opens or closes the mounting cylinder 24 through the flip stop block 41 and the reset part 42, and the overall structure is simple. Since only the mounting cylinder 24 needs to be added to the partition 23 of the traditional charging gun, and the protective structure 4 is set on the mounting cylinder 24, no other structural adjustments to the traditional charging gun structure are required. Therefore, the protective structure 4 of this utility model is suitable for traditional charging guns, has high adaptability, and can reduce costs. There is space left between the charging terminals 3 on the existing charging gun. The mounting cylinder 24, which is sleeved on the partition 23 of this utility model and is placed outside the charging terminals 3, will not cause the size of the charging gun to increase. Therefore, it can be used in traditional charging guns and has high adaptability.

[0032] In this embodiment, the flip-block 41 is provided with a rotating shaft 414, and the mounting cylinder 24 is provided with a U-shaped notch 241. The opening of the U-shaped notch 241 faces the free end of the mounting cylinder 24. Both side walls of the U-shaped notch 241 are provided with first slots 242, and the two ends of the rotating shaft 414 are respectively engaged in the corresponding first slots 242. The protective structure 4 also includes an annular end cap 43 fixed to the free end of the mounting cylinder 24. The annular end cap 43 is provided with a limiting block 431 engaged in the first slot 242, and the limiting block 431 is engaged with the rotating shaft 414. During assembly, the rotating shaft 414 of the flip-block 41 is engaged in the two side walls of the U-shaped notch 241 of the mounting cylinder 24. Then, the annular end cap 43 is fixed on the mounting cylinder 24, and the limiting block 431 of the mounting cylinder 24 abuts against the rotating shaft 414, thereby fixing the flip-block 41 on the mounting cylinder 24. The installation structure of the above-mentioned flip block 41 is simple and easy to assemble.

[0033] The flip block 41 has a receiving chamber 413, and a reset member 42 is located inside the receiving chamber 413. One end of the reset member 42 abuts against the inner wall of the receiving chamber 413, and the other end of the reset member 42 extends out of the receiving chamber 413 and abuts against the mounting cylinder 24. Installing the reset member 42 inside the flip block 41 makes the overall structure more compact.

[0034] The bottom of the U-shaped notch 241 is provided with a second slot 243. The other end of the reset piece 42 extends out of the receiving chamber 413 and is locked in the second slot 243. In this way, the other end of the reset piece 42 can be stably locked on the mounting cylinder 24, which has high reliability and avoids the problem that the reset piece 42 will detach from the mounting cylinder 24, causing the flipping block 41 to flip under its own gravity, opening the mounting cylinder 24 and failing to play a protective role.

[0035] Among them, the reset component 42 is a torsion spring, which can keep the flip stop block 41 in the closed state and also ensure that the charging gun can be smoothly inserted into the charging socket 5.

[0036] The rotating shaft 414 is located inside the receiving chamber 413, and the reset component 42 is sleeved on the rotating shaft 414. In this way, the reset component 42 can be stably installed in the receiving chamber 413 of the flip block 41 through the rotating shaft 414, thereby improving the reliability of use.

[0037] In this embodiment, the installation chamber 21, the insertion chamber 22, the partition 23 and the installation cylinder 24 are integrally formed. As a result, the overall structural strength of the insertion part 2 is higher, improving its service life and reliability. It is also easier to manufacture, for example, it can be integrally formed by injection molding.

[0038] In this embodiment, the mounting cylinder 24 is a cylindrical cylinder, and there are at least three flip-stop blocks 41 and reset members 42. Each flip-stop block 41 cooperates with a corresponding reset member 42. The free ends of the blocking parts 412 of all flip-stop blocks 41 point to the central axis of the cylindrical cylinder. In this way, the rotation radius of the blocking parts 412 of the flip-stop blocks 41 does not exceed the radius of the inner circle of the cylindrical cylinder. The space occupied by the rotating blocking parts 412 is small, and the space occupied by the rotating blocking parts 412 is more uniform. This allows the mounting cylinder 24 to be designed more compactly, and the protective structure 4 can be used in traditional charging guns, improving adaptability.

[0039] In this embodiment, there are four flip-block blocks 41, and the projection of the blocking part 412 of the flip-block block 41 is an isosceles triangle.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
