[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] like Figure 1 As shown, the utility model provides a cable retracting device for a new energy charging pile, comprising a reeling box 1 and a cable 2 movably passing through the left and right ends of the reeling box 1;

[0024] When in use, the winding box 1 is installed at an appropriate position on the charging pile, and the two ends of the cable 2 are respectively connected to the charging pile and the charging gun. When charging the new energy vehicle, the cable 2 transmits the electric energy of the charging pile to the charging gun, and then the new energy vehicle is charged through the charging gun.

[0025] like Figures 1 to 3 As shown, in this embodiment, two slide plates 3 are slidably installed in the winding box 1, and two or more winding wheels 4 are rotatably installed on the front end surface of each slide plate 3, and the cable 2 is S-shaped and cross-wound on the two sets of winding wheels 4;

[0026] A rotating electric cylinder 5 is locked and fixed on the rear end surface of the inner side of the winding box 1, and a cleaning cylinder 6 is provided on the winding box 1 to scrape away impurities on the cable 2;

[0027] The front output shaft of the rotary electric cylinder 5 is connected to the middle of the rear end surface of the transmission plate 7, and is used to drive the transmission plate 7 to rotate vertically in the winding box 1. A cylinder 8 is installed at each of the left and right ends of the front end surface of the transmission plate 7. The two cylinders 8 are respectively movably extended into the strip grooves 9 opened on the rear end surfaces of the two slide plates 3. During the rotation process of the cylinder 8, the strip grooves 9 are cooperated to drive the slide plate 3 to move vertically in the winding box 1.

[0028] In this embodiment, an annular groove is provided on the outer surface of the winding wheel 4 along the circumference, and the inner width of the annular groove corresponds to the outer diameter of the cable 2. The annular groove provides positioning for the cable 2, thereby improving the stability of the cable 2 during the contraction process;

[0029] The outer diameter of the cylinder 8 is smaller than the inner length of the strip groove 9, so that when the cylinder 8 rotates, the strip groove 9 drives the slide plate 3 to move vertically;

[0030] The reel wheels 4 on the slide plate 3 are evenly spaced, which is conducive to applying a stable pulling force to the cable 2;

[0031] In this embodiment, the rotary electric cylinder 5 is connected to an external operating device, which is a prior art;

[0032] When in use, when it is necessary to charge the new energy vehicle, the transmission plate 7 can be driven to rotate in the winding box 1 by controlling the rotating electric cylinder 5. The inclination angle of the transmission plate 7 gradually decreases. When the transmission plate 7 rotates, it drives the two cylinders 8 to rotate. The two cylinders 8 respectively cooperate with the two bar grooves 9 to pull the two slide plates 3 to move symmetrically inward in the winding box 1. The slide plates 3 respectively drive the winding wheels 4 outside thereof to move inward. The pulling force of the winding wheels 4 on the cable 2 disappears when they move inward. At this time, the charging gun can be pulled to drive the cable 2 to be discharged to charge the new energy vehicle;

[0033] After charging is completed, the rotating electric cylinder 5 is controlled to drive the two sets of winding wheels 4 to move symmetrically outward. The winding wheels 4 apply tension to the cable 2. The cable 2 is contracted on the winding wheel 4 under the tension. The winding box 1 provides protection for the cable 2 to reduce external damage to the cable 2.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the cleaning cylinder 6 includes an outer cylinder 61 vertically fixedly mounted on the winding box 1, and four annular telescopic blocks 62 are arranged in the outer cylinder 61 at equal intervals. The outer end surface of each telescopic block 62 is connected to the inner wall of the outer cylinder 61 through a spring 63, and a cleaning sponge 64 is arranged at one end of the telescopic block 62 away from the spring 63. The cleaning sponge 64 fits the side surface of the cable 2, and the cleaning sponge 64 and the telescopic block 62 are retracted inwardly by the elastic force of the spring 63, so that the cleaning sponge 64 fits tightly on the cable 2.

[0035] Among them, the telescopic block 62 and the cleaning sponge 64 are both arc-shaped structures, and the telescopic block 62 and the cleaning sponge 64 are parallel to the outer surface of the cable 2, so that the cleaning sponge 64 can be stably attached to the outer surface of the cable 2;

[0036] When in use, the cable 2 rubs against the cleaning sponge 64 during the discharge and reeling process, and the cleaning sponge 64 cleans the impurities on the cable 2 to reduce the subsequent workload of cleaning the impurities on the outer surface of the cable 2.

[0037] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
