Abstract

The invention provides a cable take-up and pay-off device and a charging pile. The cable take-up and pay-off device comprises a base body and a sliding wheel, wherein a cable is arranged on the base body in a penetrating mode, the first end of the cable is fixedly arranged on the base body and is electrically connected with a power supply network, and the second end of the cable can extend out of the base body; and the sliding wheel is rotatably and movably arranged in the base body, the cable winds around the sliding wheel, a connecting line between the first end and the second end is not parallel to the movement track line of the sliding wheel, and the sliding wheel extrudes or releases the cable when moving so as to enable the cable to be stored in or extend out of the base body. According to the cable take-up and pay-off device and the charging pile, the problem that the power and the service life of the cable are influenced by a sliding ring in the cable take-up and pay-off process in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a cable retracting and releasing device and a charging pile. Background technique [0002] The gradual replacement of fuel vehicles by electric vehicles will be an inevitable trend in future development. However, the lack of battery life and charging infrastructure has always been a prominent problem plaguing the experience of using electric vehicles, and it is also a major obstacle to the promotion of electric vehicles. [0003] The main cables in charging piles, power grid distribution, machine tools, and metallurgical industries generally use rollers to retract and unwind cables. Correspondingly, a slip ring needs to be connected to one end of the cable to ensure normal power supply of the cable. This method is only applicable to For low and medium voltage cables, when the cable transmission voltage is high, the slip ring is easily damaged, which affects the power and ...
