[0002] With the increase in the number of fuel vehicles in recent years, the environmental pollution problem has become increasingly serious. In addition, a large number of fuel vehicles will consume a large amount of non-renewable petroleum raw materials. For this reason, cleaner and more environmentally friendly new energy vehicles have gradually become the first choice of consumers, among which electric vehicles account for a large proportion of sales. At present, the charging method for electric vehicles is basically to charge with the help of special charging piles.

[0003] China Patent Authorization Announcement No. CN 207758596 U discloses an electric vehicle charging pile, including a base, an inspection door, an intelligent identifier, a human-machine interactive touch screen, a protective cover, a solar panel, a current protector, a charging gun storage slot, a charging gun, and a pile body; the protective cover is composed of a shell, a retractable roller, a retaining spring, a pull plate, and a control button. The utility model discloses an electric vehicle charging pile, which is provided with a protective cover. When the device is not in use, the pull plate seals the human-machine interactive touch screen by the fastening of the retaining spring. If the electric vehicle needs to be charged, the control button can be pressed, the retaining spring is loosened, and the pull plate can be lifted upwards. The retractable roller will be recovered. Under the protective isolation effect of the protective cover, rainwater will no longer be able to wash the surface of the human-machine interactive touch screen, and external dust is not easy to adhere to the surface of the human-machine interactive touch screen, effectively maintaining the normal operation of the equipment.

[0004] As in the above-mentioned prior art, after charging is completed, the charging cable needs to be manually wound around the outside of the charging pile, which is inconvenient. Therefore, a retractable device for the charging cable of an electric vehicle is urgently needed. Utility Model Content
