Electric steering locking device

Abstract

#CMT# # / CMT# The device (1) has a plate-like locking screw (7) displaceable between locking and unlocking positions, and an electrical actuator for displacing a cylindrical entrainment unit (6) back and forth in a displacement direction of the screw. A spring (9) pushes the screw toward the locking position. A lock stop (14) intervening in the screw is displaceably arranged in a direction transverse to the displacement direction. Another spring (15) pushes the stop into an intervention direction. The stop is engaged with the screw and displaced by an L-shaped operating member (6A) at the entrainment unit. #CMT#USE : # / CMT# Locking device for locking an electrically operated steering wheel of a car during parking. #CMT#ADVANTAGE : # / CMT# The lock stop is engaged with the locking screw in the locking position, so that force required for withdrawal of the screw from a steering shaft is reduced, thus preventing obligation-moderate unlocking of the steering wheel. The lock stop intervening in the screw is displaced in the direction transverse to the displacement direction, thus enabling selection of an operation mechanism for the operation of the screw in a relatively free manner. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a side sectional view of an electrically operated steering wheel locking device in a closed state. 1 : Locking device 6 : Cylindrical entrainment unit 6A : L-shaped operating member 7 : Plate-like locking screw 9, 15 : Springs 14 : Lock stop.

Description

technical field [0001] The invention relates to an electric steering locking device for locking the rotation of the steering wheel by electric means when the vehicle is parked. Background technique [0002] In recent years, in order to prevent theft, an electric steering lock device that electrically locks the rotation of the steering wheel when the vehicle is parked is installed on the vehicle. Such an electric steering lock device includes a lock bolt movable between a locked position engaged with a steering shaft of a vehicle and an unlocked position released from the engagement, and an electric actuator such as an electric motor that operates the lock bolt. [0003] In this electric steering lock device, when the driver puts the engine start switch in the OFF position while the engine is running, the electric motor is driven after detecting this situation, and the electric motor drives the lock bolt to the locked position. Move and engage with the steering shaft to lock...

Problems solved by technology

[0008] However, in the electric steering lock device proposed in Patent Document 1, the lock stopper is moved by a pin that operates the lock lever and moves in the direction of the rotation axis of the rotating body. Orthogonal, which limits the structure that can be used as the working mechanism to make the locking lever work
