Description

Technical Field

[0001] The utility model relates to the field of charging piles, in particular to a charging pile. Background Art

[0002] Charging stations, as essential supporting infrastructure for electric vehicles, play a key role in providing them with electrical energy. They convert AC or DC power from the power grid into a form of electricity suitable for charging electric vehicle batteries, enabling fast and safe charging of electric vehicles. Charging stations are designed with ease of use and convenience in mind. Users simply insert the charging plug into the electric vehicle's charging port and follow the instructions to begin charging. With technological advancements, many charging stations are now equipped with intelligent management systems that monitor charging status in real time, control charging power, and automatically shut off power upon completion, ensuring a safe and efficient charging process.

[0003] For example, the invention patent for a charging pile with the application number CN202211100316.9 is named, which includes a winding device, a control panel, a main body, a heat sink, a protective socket, a charging gun, a charging cable and a control module, wherein the control panel is arranged on the main body, and is used to display the current working status of the charging pile and to control the operation of the charging pile; the charging gun is electrically connected to one end of the charging cable, and the other end of the charging cable passes through the main body and extends into the interior of the winding device, and is electrically connected to the interior of the main body. Due to the long charging distance, the charging pile usually needs to be equipped with a long charging cable. Since the cable is heavy, the charging cable needs to be frequently dragged during and after the charging process, which can easily cause the charging cable to wear and affect the charging process. However, the charging cable of a conventional charging pile is directly electrically connected to the inside of the main body, resulting in the need to replace all the charging cables after they are worn. The replacement cost is high, which can easily lead to waste of resources. Utility Model Content

The external charging cable 2 is passed through the clearance channel 42, and the opening size of the clearance channel 42 is smaller than the size of the first interface 21, that is, the first interface 21 is against the inner channel opening of the clearance channel 42. The clearance channel 42 is provided for the external charging cable 2 to pass through and route, and a smaller opening of the clearance channel 42 is provided so that the end of the first interface 21 away from the inner interface 111 is against the inner wall of the first limiting cavity 41. The first limiting component 4 provides a limiting force for the first interface 21 toward the inner interface 111, further ensuring the stability of the connection between the first interface 21 and the inner interface 111.

[0053] Specifically, the first limiting assembly 4 includes a first limiting block 43 and a second limiting block 44 that are arranged opposite to each other. A baffle 432 is fixed on one side of the first limiting block 43 and the second limiting block 44, and a clearance notch 4321 is provided on the baffle 432.

[0060] Please refer to Figure 1-3 As shown, in this embodiment, a gun hanging channel 12 is opened on the cabinet 1, and a wire hanging baffle 13 is fixed to the cabinet 1. The wire hanging baffle 13 is arranged around the top and side of the gun hanging channel 12, and the charging gun 3 is hung in the gun hanging channel 12. The wiring channel 14 is located below the gun hanging channel 12, and the wiring channel 14 and the gun hanging channel 12 are located within the height range of 11 / 3-1 / 2 of the cabinet. The position between the wiring channel 14 and the gun hanging channel 12 is limited to ensure that the wiring channel 14 is located at a higher position, which is convenient for the user to drag the external charging cable 2, making the charging process more labor-saving. The wire hanging baffle 13 blocks the gun hanging channel 12 and the wiring channel 14, improving the waterproof performance of the gun hanging channel 12 and the wiring channel 14, and at the same time provides a placement position for the external charging cable 2, which is convenient for the external charging cable 2 to be suspended and stored, reducing the friction between the external charging cable 2 and the ground.

[0061] Furthermore, the cabinet body 1 is provided with an inwardly recessed groove 15, and the inner top surface 151 of the inwardly recessed groove 15 is an inclined surface. The inner top surface 151 is inclined inwardly from the notch of the inwardly recessed groove 15 to the bottom of the groove, and the wiring channel 14 is provided on the inner top surface 151 of the inwardly recessed groove 15. The inner groove further enhances the waterproofness of the wiring channel 14, preventing water from entering the cabinet body 1 and affecting the operation of the internal charging mechanism 19. Moreover, the inner top surface 151 is inclined inwardly from the notch of the inwardly recessed groove 15 to the bottom of the groove. When the external charging cable 2 is installed, it is perpendicular to the inner top surface 151, so that the first interface 21 of the external charging cable 2 is in a naturally drooping state, preventing the peripheral side of the external charging cable 2 from being in a bent state at the wiring channel 14, reducing the friction between the external charging cable 2 and the wiring channel 14, and improving the service life of the external charging cable 2.

[0062] Please refer to Figure 2 and Figure 3 As shown, in this embodiment, a limiting bracket 16 is fixed inside the cabinet 1, and the limiting bracket 16 is located above the wiring channel 14. A limiting clamp 17 is provided on the limiting bracket 16. The end face 161 of the limiting bracket 16, the inner charging line 11, and the bent portion 171 of the limiting clamp 17 enclose a limiting channel 18. The end of the inner charging line 11 passes through the limiting channel 18 and extends toward the wiring channel 14. The limiting clamp 17 and the limiting portion limit the circumference of the end of the inner charging line 11, further ensuring the stability of the connection between the inner charging line 11 and the external charging line 2. Please refer to Figure 3 As shown, the extended plane of the end surface 161 between the limiters is perpendicular to the extended plane of the inner top surface 151 of the inner recessed groove 15. This allows the inner charging cable 11 to extend in a straight line toward the routing channel 14, reducing bending of the inner charging cable 11, extending the service life of the inner charging cable 11, and reducing costs.

[0063] In this embodiment, the charging mechanism 19 is a high-voltage and low-voltage power supply device inside a conventional charging pile, which charges the new energy vehicle through the internal charging line 11 and the external charging and charging gun 3.

[0064] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
