Abstract
The utility model discloses an electronic steering column locking device. A groove in an Archimedes spiral shape and arranged on one end face of a worm wheel is used for driving a contact slide block, the contact slide block drives a spring bolt to move vertically, meanwhile, a spiral groove in the other side of the worm wheel drives a safety slide block to move horizontally, and therefore a microswitch is triggered to correspondingly output a locking signal or an unlocking signal while locking and unlocking of an electronic steering column can be achieved. Thus, the number of transmission parts of the whole transmission device is small, structure is simple and compact, product size is small, transmission is stable and assembly is simple. By means of the safety slide block, misoperation of the spring bolt can be constrained in a mechanical structure, and therefore safety of the whole device can be improved.
