Description

[Technical field]

[0001] The present invention relates to the technical field of charging stations, and more particularly to a cantilevered, labor-saving winding mechanism for a charging cable of a charging station. [Background technology]

[0002] A charging station is a charging facility that provides charging services for electric vehicles and can charge various types of electric vehicles according to different voltage levels.

[0003] In order to adapt to new energy vehicles with different charging port locations and inclined parking conditions in private parking spaces, the charging gun of a charging station often needs to be pulled out a certain distance when connecting to the charging port of an electric vehicle. Since the cable is not wound up, it is often pulled around the charging station and exposed, and when a user uses it, dirt on the cable is likely to adhere to the user's clothes. In particular, in the case of a fast-charging charging station, the charging gun and cable are heavier, which places a heavy burden on the body of users who are not good at carrying heavy things, such as women, the elderly, and people with disabilities. The outer part of the cable is easily worn or broken due to exposure to sunlight and rain and friction with the ground, which affects its service life and creates other safety risks.

[0004] A Chinese utility model with the registration publication number CN218876917U discloses a cable winding mechanism for an automobile charging stand and has the function. The mechanism includes a charging stand body, a fixed base, a charging gun, and a cable, and a cable guide hole is provided on the right side of the lower part of the charging stand body, and a fixed base is provided on the right side of the upper part of the charging stand body. After the mechanism pulls out the cable from the charging stand body, it also drags it on the ground, which causes wear of the cable and affects the normal charging operation of the charging stand. Summary of the Invention [Problem to be solved by the invention]

[0005] The objective of the present invention is to provide a cantilevered, labor-saving winding mechanism for a charging cable at a charging station, which can automatically pull and wind the cable, and prevent the cable from being pulled around the parking space by itself and being rubbed against the ground, resulting in wear.

[0014] The beneficial effects of the present invention are as follows: 1. According to the present invention, the cantilevered labor-saving winding mechanism for the charging cable of the charging stand is installed above the charging power source by the stand, and the cable is pressed by the pressing roller of the pressing frame, and then the driving motor rotates forward and backward, which makes it easy to directly wind and rewind the cable, which makes it easier for users who are not good at handling heavy objects to use and saves physical strength, and prevents the cable from being pulled around the charging stand. It also prevents the cable from being crushed by cars when it is scattered in the parking space.

[0015] 2. In the cantilever-type labor-saving winding mechanism of the charging cable of the charging station, the outer surfaces of the first cable guide roller, the second cable guide roller, the third cable guide roller and the fourth cable guide roller are designed with a soft material to prevent friction with the outer surface of the cable, effectively avoiding wear caused by friction of the cable and extending the service life of the cable.
