Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and more specifically, relates to an auxiliary plugging device for a charging pile. Background Art

[0002] Charging piles and charging guns are key components in an electric vehicle charging system, each playing different functions. A charging pile, also known as a charging station or charging terminal, is the infrastructure for electric vehicle charging. It is usually fixedly installed in public or private places, such as parking lots, roadside or shopping malls. The main function of a charging pile is to supply power to an electric vehicle and ensure the safety and efficiency of the charging process. A charging pile includes power conversion equipment, a control system, a display screen, and a communication interface. The power conversion equipment is responsible for converting the power from the power grid into a voltage and current suitable for the electric vehicle battery. The control system manages the charging process, including starting, stopping charging, monitoring current and voltage, and calculating fees, etc. The display screen provides user information, such as charging status and fees. The communication interface is used for data exchange with the electric vehicle and other systems (such as a payment system).

[0003] A charging gun, also known as a charging gun head or charging cable, is the actual physical interface connecting the charging pile and the electric vehicle. One end of the charging gun is connected to the charging pile by a cable of the charging pile, and the other end is inserted into the charging port of the electric vehicle. The charging gun contains multiple electrical contacts, and these contacts transmit power to the electric vehicle battery through the cable. Modern charging guns may also include control and data communication functions to ensure the safety and effectiveness of the charging process.

[0004] Currently, charging piles may lack an effective guiding device, resulting in the charging gun being unable to be smoothly inserted into the correct position. Summary of the Utility Model

[0005] In view of this, the utility model provides an auxiliary plugging device for a charging pile, aiming to solve the problem that charging piles may lack an effective guiding device, resulting in the charging gun being unable to be smoothly inserted into the correct position.

[0006] The utility model is implemented as follows:

[0007] The present utility model provides an auxiliary plugging device for a charging gun of a charging pile, which includes a positioning mechanism, a positioning pin, a mating frame, and a charging gun head. The mating frame is a hollow structure that penetrates up and down. The mating frame is arranged outside the charging gun head, and the mating frame cooperates with the plug interface to position and plug the charging gun head. The positioning mechanism includes a positioning mechanism body, a plug interface, a positioning groove, and a positioning seat. The plug interface is opened above the middle of the positioning mechanism body. The lower part of the plug interface is a plugging channel. During plugging, the mating frame and the plug interface cooperate to be inserted into the plug interface, and the sizes of the plug interface and the mating frame are adapted to each other. The positioning pin is fixedly arranged on one side of the mating frame, and the positioning pin is inserted into the positioning groove. The sizes of the positioning pin and the positioning groove are adapted to each other. The positioning pin is used to position the plugging position of the charging gun head.

[0008] The technical effects of the auxiliary plugging device for a charging gun of a charging pile provided by the present utility model are as follows: By setting the positioning pin, it is beneficial to prevent the charging gun head from moving out of position or deviating from the predetermined position during plugging, thereby ensuring the accuracy of plugging and positioning.

[0009] On the basis of the above technical solution, the auxiliary plugging device for a charging gun of a charging pile of the present utility model can also be improved as follows:

[0010] Among them, the side wall of the mating frame is a three-section structure. The upper section is a concave arc structure, the middle section is a vertical structure, and the lower section is an arc structure that bends towards the center of the mating frame.

[0011] The beneficial effect of adopting the above improvement scheme is that by setting the side wall of the mating frame as a three-section structure, the mating frame can better cooperate with and fix the charging gun head, ensuring the stability and accuracy of plugging.

[0012] Furthermore, the circumferential diameter of the lower end of the mating frame is smaller than the circumferential diameter of the upper end of the mating frame.

[0013] The beneficial effect of adopting the above improvement scheme is that by setting the circumferential diameter of the lower end of the mating frame to be smaller than the circumferential diameter of the upper end of the mating frame, the lower end of the mating frame can smoothly enter the plug interface to limit the charging gun head, enabling the charging gun head to be positioned and plugged.

[0014] Furthermore, the inside of the plug interface is hollow and penetrates up and down. The plug interface is located directly above the plugging position.

[0015] Furthermore, the height of the plugging channel is 2 cm.

[0016] The beneficial effect of adopting the above improvement scheme is that by setting the height of the plugging channel to be 3 cm, the plug interface can be protected.

[0017] Further, the insertion channel is in communication with the insertion port.

[0018] Further, the length of the positioning pin is greater than the length of the mating frame.

[0019] The beneficial effects of adopting the above improvement scheme are as follows: By setting the length of the positioning pin to be greater than the length of the mating frame, the accuracy and stability of the insertion position are ensured, positioning errors are avoided, and the good matching between the positioning pin and the positioning groove enhances the stability and precision during insertion.

[0020] Further, the positions of the mating frame and the positioning pin correspond to the positions of the insertion port and the positioning groove.

[0021] Further, an anti-slip layer is provided on the lower wall of the positioning seat.

[0022] The beneficial effects of adopting the above improvement scheme are as follows: By providing an anti-slip layer on the lower wall of the positioning seat, sliding can be prevented, which is beneficial to ensuring the stability during insertion.

[0023] Further, the material of the anti-slip layer is rubber.

[0024] Compared with the prior art, the beneficial effects of an auxiliary plugging device for a charging pile provided by the present utility model are as follows: By providing a positioning pin, it is beneficial to prevent the charging gun head from moving out of position or deviating from the predetermined position during insertion, thereby ensuring the accuracy of the plugging positioning. By setting the side wall of the mating frame to be a three-section structure, the mating frame can better cooperate with and fix the charging gun head, ensuring the stability and precision of the insertion. By setting the circumferential diameter of the lower end of the mating frame to be smaller than the circumferential diameter of the upper end of the mating frame, the lower end of the mating frame can smoothly enter the insertion port to limit the charging gun head, enabling the charging gun head to be positioned and inserted. By setting the height of the insertion channel to be 3 cm, the insertion port can be protected. By setting the length of the positioning pin to be greater than the length of the mating frame, the accuracy and stability of the insertion position are ensured, positioning errors are avoided, and the good matching between the positioning pin and the positioning groove enhances the stability and precision during insertion. By providing an anti-slip layer on the lower wall of the positioning seat, sliding can be prevented, which is beneficial to ensuring the stability during insertion. It can solve the problem that the charging pile may lack an effective guiding device, resulting in the charging gun being unable to be smoothly inserted into the correct position.

The matching frame 3 is arranged outside the charging gun head 4, and the matching frame 3 cooperates with the insertion interface 12 to perform positioning and plugging of the charging gun head 4; the positioning mechanism 1 includes a positioning mechanism body 11, an insertion interface 12, a positioning groove 13, and a positioning seat 14; an insertion interface 12 is opened above the middle of the positioning mechanism body 11, and the lower part of the insertion interface 12 is an insertion channel. During insertion, the matching frame 3 and the insertion interface 12 cooperate to be inserted into the insertion interface 12, and the sizes of the insertion interface 12 and the matching frame 3 are adapted to each other; the positioning pin 2 is fixedly arranged on one side of the matching frame 3, and the positioning pin 2 is inserted into the positioning groove 13. The sizes of the positioning pin 2 and the positioning groove 13 are adapted to each other, and the positioning pin 2 is used to position the insertion position of the charging gun head 4.

[0031] During use, fit the mating frame 3 over the outer side of the charging gun head 4, place the positioning mechanism 1 outside the charging socket and fix it to ensure that the insertion interface 12 corresponds to the charging port. Move the charging gun head 4 to correspond to the insertion interface 12. The charging gun head 4 moves inward so that the positioning pin 2 is inserted into the positioning groove 13. Since the length of the positioning pin 2 is longer than that of the mating frame 3, the positioning pin 2 will be inserted into the positioning groove 13 earlier than the mating frame 3. When the positioning pin 2 can increase the stability of positioning, move the charging gun head 4 downward so that the mating frame 3 is inserted into the insertion interface 12, and the side wall of the mating frame 3 fits against the inner wall of the insertion interface 12 to ensure the stability when the charging gun head 4 is plugged in.

[0032] Among them, in the above technical solution, the side wall of the mating frame 3 is a three-section structure. The upper section is a concave arc structure, the middle section is a vertical structure, and the lower section is an arc structure that bends towards the center of the mating frame 3.

[0033] Further, in the above technical solution, the circumferential diameter of the lower end of the mating frame 3 is smaller than the circumferential diameter of the upper end of the mating frame 3.

[0034] Further, in the above technical solution, the inside of the insertion interface 12 is hollow and runs through up and down. The insertion interface 12 is located directly above the insertion position.

[0035] Further, in the above technical solution, the height of the insertion channel is 2 cm.

[0036] Further, in the above technical solution, the insertion channel is connected to the insertion interface 12.

The charging gun head 4 is moved to correspond to the insertion interface 12. The charging gun head 4 moves inward so that the positioning pin 2 is inserted into the positioning groove 13. Since the length of the positioning pin 2 is longer than that of the fitting frame 3, the positioning pin 2 will be inserted into the positioning groove 13 earlier than the fitting frame 3. When the positioning pin 2 can increase the stability of positioning, the charging gun head 4 is moved downward so that the fitting frame 3 is inserted into the insertion interface 12, and the side wall of the fitting frame 3 is in contact with the inner wall of the insertion interface 12, ensuring the stability when the charging gun head 4 is plugged in.
