Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Since the traditional charging plug 2 and the power cord 3 are directly hung on the charging pile, the power cord 3 will be dragged on the ground when the charging plug 2 is used for charging. After long-term use, the power cord 3 is seriously worn and easily causes certain safety hazards. In order to reduce the wear of the power cord 3 when it is retracted and extended, and to extend the service life of the power cord 3, reference Figure 1 - Figure 5 The utility model provides an outdoor charging pile, which consists of a pile body 1, two charging plugs 2, two power cords 3 and a retracting mechanism 4.

[0027] In order to drive the reel 42 to rotate forward and reverse to reel in or unwind the power cord 3, refer to Figure 4 and Figure 5 Specifically, the driving assembly 45 includes a rotating shaft 451 fixedly arranged at one end of the winding drum 42 and located in the vertical installation groove 41, and the rotating shaft 451 rotates with the pile body 1 through a bearing at one end away from the winding drum 42, and a transmission gear 452 fixedly arranged on the rotating shaft 451, and a vertical rack 453 is meshed and transmitted on one side of the transmission gear 452. A servo cylinder 454 fixed to the pile body 1 and used to drive the vertical rack 453 to move up and down is arranged at the inner bottom of the vertical installation groove 41. The servo cylinder 454 is automatically controlled by a controller. When the charging plug 2 is pulled out or inserted, the controller transmits information to the servo cylinder 454, thereby driving the servo cylinder 454. The output shaft of the servo cylinder 454 pulls the vertical rack 453 upward or downward. The control circuit of the controller can be realized by simple programming by technicians in this field, and the utility model is mainly used to protect mechanical devices.

[0028] In order to effectively clean the stains on the power cord 3 and reduce the corrosion of the outer skin of the power cord 3, refer to Figure 4Specifically, the wiping assembly 46 includes a horizontal rack 461 arranged at the bottom of the transmission gear 452, and the horizontal rack 461 and the vertical rack 453 are staggered with each other, a sliding horizontal groove opened on the side wall of the pile body 1 is arranged on one side of the horizontal rack 461, and a connecting cross bar 463 sliding with the sliding horizontal groove is arranged at the bottom of one side of the winding drum 42, and one end of the connecting cross bar 463 passes through the sliding horizontal groove and is fixedly connected to the horizontal rack 461, and a fixing seat 464 is fixedly arranged at the other end of the connecting cross bar 463, and a movable magnetic suction is arranged on one side of the fixing seat 464. The fixed seat 464 and the movable seat 465 are respectively fixedly bonded with wiping sponges 466 on the inner sides thereof, and the cross-sections of the two wiping sponges 466 are set to be semi-circular, and the two wiping sponges 466 wrap the power cord 3.
