Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, but should not be construed as limiting the present utility model.

The charging cable installation structure of this embodiment, referring to Fig. 1 and Fig. 3, is provided with a first threading hole 11 on the charging pile casing 1, and the installation structure includes a mounting plate 2 arranged in the charging pile casing 1, fixed on The central column 3 on the mounting plate 2, the rotating disk 4 rotatably arranged on the central column 3, and the scroll spring 5 used to drive the charging cable A to rewind, the charging cable A and the unfolded scroll The springs 5 are fixed together so that the charging cable A is rolled up with the scroll spring 5, and one end of the scroll spring 5 is fixed on the central column 3, and the charging cable is set with the scroll spring 5 On the rotating disk 4, one end of the charging cable is extended from the central column 3 and connected to the module inside the charging pile, and the other end is provided with a plug, which is located outside the charging pile housing.

When charging, the operator holds the plug and pulls the charging cable. Since the charging cable can only pass through the first threading hole 11, the rotating disk 4 will rotate, the charging cable will be unfolded and pulled out, and the scroll spring 5 will be pulled out. Compression, after being pulled to a suitable length, insert the plug into the socket of the car to charge; after charging is completed, pull out the plug from the socket, loosen the plug, the rebound elasticity of the scroll spring 5 will drive the pulled out charging cable Cable rewinds automatically.

The installation structure of the charging cable in this embodiment is provided with a volute spring 5, so that the charging cable can be automatically rewound and recovered after being pulled out, and the cable that is charging the car is held under the action of the volute spring 5. The tensioned state can prevent the charging cable from contacting the ground, avoid stepping on the charging cable, prevent the charging cable from being entangled, and improve the service life of the charging cable

In an optimized embodiment, referring to Fig. 2 and Fig. 3, a limiting case 6 is arranged on the mounting plate 2, and the volute spring 5 and the charging cable coiled with the volute spring 5 should be covered in the limiting case 6, the outer wall of the limiting shell 6 is provided with a second threading hole 61 for the charging cable to pass through the limiting shell 6, and the limiting shell 6 can make the charging cable rewind in a more orderly manner.
