Abstract

The invention provides a winding and locking device, which comprises a ratchet wheel, a cam and a limit part, wherein the ratchet wheel is connected with the cam through a wheel shaft; the limit part comprises a first limit unit and a second limit unit; the first limit unit is arranged between the ratchet wheel and the cam; an outer edge limit unit is arranged between the outer edges of the ratchet wheel and the cam. According to the locking device provided by the invention, the cam can rotate along with the ratchet wheel and can stop at the current position at any time when the winding device draws wires, and the cam cannot rotate along with the ratchet wheel during the rewinding process, so smooth winding is ensured, and the adaptability is better.

Description

technical field [0001] The invention relates to the technical field of charging wire storage for pure electric vehicles, in particular to a wire winding locking device. Background technique [0002] Electric vehicles need to be connected to the charging pile through an external charging cable to charge the vehicle. The length of the charging cable that comes with the car is usually fixed. crushed or soiled. At present, when an electric vehicle needs to be charged, after the charging is completed, the owner will place the charging cable in the trunk and other spaces at will. Contents of the invention [0003] In view of this, the present invention provides a wire winding locking device, aiming at solving the problem of winding storage of charging wires of pure electric vehicles. [0004] The technical scheme adopted in the present invention is specifically: [0005] A winding locking device, comprising a ratchet, a cam and a limiting portion, the ratchet and the cam are ...
