Abstract

The invention provides an electric locking device which comprises a motor, a worm, a worm gear, a nut and a screw rod. The worm is installed on an output shaft of the motor, the worm gear is in transmission connection with the worm, and the screw rod is in transmission connection with the nut which is connected with the worm gear. The electric locking device further comprises a lower cover, wherein a first locating groove and a second locating groove are formed in the lower cover, and the motor is located through the first locating groove and the second locating groove. According to the electric locking device, the locating accuracy of the motor is high, installation is convenient, stable transmission between the worm and the worm gear is better ensured, errors caused by vibration of a vehicle are reduced, and the electric locking device is flexible to move and cannot be clamped easily.

Description

technical field [0001] The invention relates to an electric locking device, in particular to a vehicle steering electric locking device, which belongs to the technical field of automobiles. [0002] Background technique [0003] Most of the moving parts of the existing vehicle steering electric locking device are completed by utilizing mechanical transmission to convert the forward and reverse rotation of the motor into the stretching and retracting actions of the dead bolt. Specifically, a worm is installed on the output shaft of the motor. With the rotation of the motor shaft, the worm also rotates to drive the worm wheel. A nut is nested on the central axis of the worm wheel. A screw is arranged in the nut, and a lock tongue is connected at the end of the screw. The screw can also be used as a The lock tongue converts the rotation of the nut into the linear movement of the screw, thereby driving the lock tongue to produce the movement of extending and retracting, and is ...
