AI Technical Summary

Technical Problem

When one end of the traditional cable retracting and discharging mechanism is fixed, the problem of wire stirring is prone to occur, especially in special occasions such as charging piles.

Method used

A fixed line retracting and retracting mechanism is designed, adopting the relative movement of the static slip ring and the moving slip ring, and transmits current through the contact between the static slip ring and the brush of the moving slip ring, and uses shafts and transitions of different diameters to closely cooperate with the reel to realize the retracting and retracting of the wires.

Benefits of technology

It realizes that the wire can be retracted and released smoothly when one end of the wire is fixed, avoiding the phenomenon of wire stirring, and is suitable for special occasions such as charging piles.

Abstract

The utility model discloses a take-up and pay-off mechanism with one fixed end. The take-up and pay-off mechanism comprises a winding drum, a first electric wire, a shaft, a static slip ring and a movable slip ring. In the winding process of the first electric wire, the static slip ring and the movable slip ring move relatively, the ring channel on the static slip ring is in contact with the electric brush on the movable slip ring, and current is transmitted to the movable slip ring from the static slip ring. The wire on the movable slip ring brush is connected with the first wire, and the ring channel on the static slip ring is connected with the second wire, so that the first wire can still be taken up under the condition that the other end is fixed. According to the shaft, the diameter of the first diameter section is smaller than that of the second diameter section, and in the assembling process, the static slip ring can be conveniently assembled from the first diameter section in a sleeving mode. The shaft is a hollow shaft, and a second electric wire can conveniently penetrate into the hollow shaft. Transition wheels of different sizes are adopted, and the bearing is ingeniously connected with the winding drum.
