Abstract
An electronic steering wheel lock apparatus having high reliability. The electronic steering wheel lock apparatus (11) includes a lock pin (12) for locking a steering shaft (21). The lock pin (12) is moved by a motor or a plate cam (41). When an engine is activated and the steering shaft is unlocked, a solenoid (31) is engaged with the plate cam (41) to restrict the movement of the plate cam (41).
Claims11
A lock mechanism for a steering shaft and responsive to an operation of a starter in a vehicle, the lock mechanism comprising:
- a locking means for selectively locking the steering shaft;
- a first actuator for moving the locking means, wherein the first actuator includes a motor and a cam, wherein the cam is connected to the motor, contacts the locking means, and includes an engaging portion;
- and
- a second actuator for engaging the first actuator and restricting the movement of the first actuator, the second actuator being disengaged from the first actuator in response to the operation of the starter to enable the movement of the first actuator, wherein the engaging portion is engaged with the second actuator, and the second actuator includes a solenoid.
A lock mechanism for a steering shaft, the lock mechanism comprising:
- a locking means for selectively locking a steering shaft;
- an urging means for urging the locking means in a direction that releases the locking of the locking means;
- a first actuator for moving the locking means against the force of the urging means;
- and
- a second actuator for engaging the first actuator and restricting the movement of the first actuator, the second actuator enabling the movement of the first actuator by disengaging the first actuator when the locking means unlocks the steering shaft.
