Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a quick connection plug structure for a new energy charging pile. Background Technique

[0002] A new energy charging pile is a device that provides charging services for plug-in new energy vehicles. Its power input end is connected to the AC power grid, and the power output end is connected to the charging interface of the vehicle through a charging gun to achieve the charging process. The charging gun is the main device for charging new energy vehicles. When in use, connecting the charging gun to the vehicle can charge the new energy vehicle.

[0003] After the charging gun completes the charging operation, in order to facilitate the storage of the charging gun, most new energy charging piles are provided with storage structures, such as common hanging racks and sockets, etc. Among them, the socket is more widely used. After use, the gun head of the charging gun can be directly inserted into the socket. Although this plugging method has the advantages of convenient operation and easy storage, due to the lack of an effective limiting structure between the charging gun and the socket, the connection firmness between the charging gun and the socket is poor. Affected by external factors (such as strong wind and other weather), the charging gun may fall off, which may easily lead to leakage or damage. In view of this, we propose a quick connection plug structure for a new energy charging pile. Content of the Utility Model

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a technical solution:

[0028] Please refer to Figures 1 - 6 As shown, the structure of the quick connection plug of the new energy charging pile includes a gun body 1. A baffle 11 is coaxially fixed at the front end of the outer wall of the gun body 1. A hollow shell 13 is fixed above the rear end face of the baffle 11. The shell 13 is fixedly connected to the baffle 11 and the gun body 1 by bolts. A notch 130 is opened at the rear end of the shell 13; two guide rods 14 are fixed inside the shell 13. A liftable movable plate 16 is slidably installed between the two guide rods 14. The rear end of the movable plate 16 passes through the notch 130. Springs 15 for pressing against the movable plate 16 are sleeved at the bottom ends of the guide rods 14; A latch 18 is installed at the top of the movable plate 16. The latch 18 passes through the shell 13 and protrudes above the shell 13; A charging pile socket 2 is provided on the front side of the gun body 1. A sealing cavity 20 is opened at the rear end of the charging pile socket 2. A slot 22 is opened at the front end of the sealing cavity 20. A card slot 21 is opened at the top of the sealing cavity 20; The front end of the gun body 1 is in plug-in fit with the slot 22. The baffle 11 is in plug-in fit with the sealing cavity 20, and the latch 18 is in snap-fit with the card slot 21.

[0029] In this embodiment, a slope 180 is opened at the top of the latch 18, and the slope 180 is inclined. The setting of the slope 180 facilitates guiding the latch 18 into the card slot 21, reducing jamming and obstruction, and making the operation smoother.

[0030] In this embodiment, a pressing block 17 is closely adhered to the top rear end of the movable plate 16, and the pressing block 17 is made of rubber material. The rubber pressing block has elasticity, can provide a buffering effect, improves the use comfort, and at the same time, the close adhesion ensures the connection stability.

[0031] In this embodiment, guide rails 131 are fixed on both inner walls of the shell 13. Guide grooves 161 slidably connected to the guide rails 131 are opened on both side walls of the movable plate 16. This design ensures the accuracy and stability of the movement of the movable plate 16, reducing deviation and shaking.

[0032] In this embodiment, a plurality of positioning posts 12 are installed on the front end face of the baffle 11, a plurality of positioning holes 23 are formed on the front end face of the sealing cavity 20, and the positioning posts 12 are inserted and matched with the positioning holes 23. The insertion and matching of the positioning posts 12 and the positioning holes 23 helps to quickly and accurately install the baffle 11, ensure the accuracy of the installation position, and at the same time improve the stability of the installation of the gun body 1.

[0033] In this embodiment, a handle 10 is installed at the rear end of the bottom of the gun body 1, and the handle 10 is inclined. The inclined handle 10 conforms to the ergonomic design, is convenient for the operator to hold, and provides a comfortable operation experience.

[0034] In this embodiment, the cross-sectional shape of the baffle 11 is circular, and the baffle 11 is fixedly connected to the gun body 1 by bolts. The bolt connection method is simple and reliable, which is convenient for installation and disassembly, and the circular shape is beneficial to the cooperation between the baffle 11 and the sealing cavity 20.

[0035] It should be added that the size of the notch 130 in this embodiment is adapted to the size of the movable plate 16. This design is beneficial to the smooth lifting and lowering of the movable plate 16 at the notch 130, and ensures the stability of the movable plate 16.

[0036] During specific use, the user first inserts the front end of the gun body 1 into the slot 22. At the same time, the user presses down the pressing block 17. The pressing block 17 drives the movable plate 16 to move downward. The movable plate 16 then moves downward along the two guide rods 14, and the spring 15 is compressed by the movable plate 16. At this time, the movable plate 16 drives the latch 18 to retract into the housing 13. When the front end of the gun body 1 is inserted into the slot 22, the baffle 11 is inserted into the sealing cavity 20, and the positioning post 12 is inserted into the positioning hole 23. At this time, the latch 18 moves to directly below the card slot 21. Subsequently, the user releases the pressing block 17. Under the elastic action of the spring 15, the movable plate 16 moves upward along the two guide rods 14. The movable plate 16 drives the latch 18 to move upward, and the top end of the latch 18 is simultaneously clamped into the card slot 21, and the gun body 1 is connected and fixed to the charging pile socket 2.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention.
