The user picks up the charging gun 11 and pulls the charging cable 10 outward. In the process of pulling the charging cable 10 outward, the rotating ring 7 is driven to rotate. The rotating ring 7 drives the foot pedal 20 to move upward through the follower assembly. Specifically, the rotating ring 7 drives the annular gear ring 14 to rotate, the annular gear ring 14 drives the gear a15 to rotate, the gear a15 drives the winding wheel 16 to rotate, and the winding wheel 16 starts to reel in the wire, thereby driving the foot pedal 20 to move upward through the pull rope 18. When the foot pedal 20 moves to the top, it indicates that the charging cable 10 has been pulled out to the maximum length and cannot be pulled out any further. S3. After charging is completed, the user removes the charging gun 11 from the new energy vehicle, places the charging gun 11 on the lower sealing plate 25, and fixes the charging gun 11 through the limiting rod 27 and the limiting hole; S4. Use your foot to step on the pedal 20 to the bottom, and drive the rotating ring 7 to rotate through the follower assembly to complete the rapid winding of the charging cable 10. Specifically, the pedal 20 drives the winding wheel 16 to rotate through the pull rope 18, and the winding wheel then drives the annular gear ring 14 to rotate through the gear a15, and the annular gear ring 14 drives the rotating ring 7 to rotate, and the rotating ring 7 rotates, while the cable winding disk 6 is fixed, so that the charging cable 10 is continuously wound on the cable winding disk 6; S5. The user controls the motor 31 through the mobile phone, and the rotating shaft 22 rotates counterclockwise to flip the lower sealing plate 25 upward, so that the charging gun 11 is put into the protective shell 3 and the avoidance port is closed, so as to achieve the sealing of the protective shell 3 in the non-charging state.

[0027] In summary, in the present invention, when charging, the charging gun 11 is located outside the protective shell 3, and the avoidance opening at the bottom of the protective shell 3 is closed by the upper sealing plate 24, which can ensure the airtightness of the protective shell 3 in the charging state and provide protection for the charging pile body 4; when not charging, the charging gun 11 and the charging cable 10 are all received in the protective shell 3, and the avoidance opening is closed by the lower sealing plate 25, which also ensures the sealing of the protective shell 3, provides protection for the charging gun 11 and the charging cable 10, and can prevent the charging gun 11 and the charging cable 10 from being damaged due to long-term exposure to the outside, thereby extending the service life of the charging pile; and the cable winding drum 6 surrounds the outer periphery of the charging pile body 4, does not occupy a large space, and has a relatively compact structural layout, which is conducive to reducing the installation space; in addition, after charging is completed, the charging cable 10 can be quickly and neatly wound and stored by pressing the foot pedal 20 with the foot, which is more convenient to use than manually winding the charging cable 10 around the charging pile body 4 in the prior art.
