That is, the locking groove of the steering shaft 125 is formed in the region of the steering shaft 125 that is wrapped by the shaft receiving portion 120, the locking pin protruding from the main body 110 to the shaft receiving portion 120 ( The steering shaft 125 is locked by 340 being coupled to the locking groove 126.

The ignition switch 170, more specifically, the rotor 310 connected to the ignition switch has a receiving groove 151 into which the mover 210 of the actuator 200 can be inserted. When the mover 210 is inserted into the receiving groove 151, the rotation of the lock pin 340 is suppressed by preventing the rotation of the key 160. That is, the locking pin 340 is coupled to the locking groove 126 to maintain the steering shaft 125 in a locked state.

The actuator 200 is coupled to the outer side of the ignition lock body 100, more specifically, to the outer wall of the ignition switch mounting groove 130. In the ignition lock body 100, a through hole 152 is formed so that the mover 210 is selectively inserted into the receiving groove 151 of the ignition switch 170 via the through hole 152.

A more detailed description of the actuator is shown in FIG. 5. 5 is a cross-sectional view of the actuator according to the present invention.

As shown therein, the actuator 200 includes a housing 220 having a through hole 211 formed at one side thereof, a solenoid 230 housed in the housing 220, and moved by electromagnetic force. And a mover 210 coupled to or integrally formed with the solenoid 230.

In this embodiment, the moving rod 245 is moved by the solenoid 230, the coil spring 240 is provided on the outside. The end of the moving bar 245 is provided with a limit member 250, the mover 210 is coupled to the outside.

When the electromagnetic force is not applied to the solenoid 230, a force that pushes the coil spring 240 until the limit member 250 contacts the inner surface of the housing 220 is applied. Therefore, the mover 210 coupled with the limit member 250 is advanced, and as a result, the mover 210 is coupled to the receiving groove 151 of the ignition switch 170.

When electromagnetic force acts on the solenoid 230, the moving rod 245, the limit member 250 and the mover 210 are reversed, and the mover 210 is separated from the receiving groove 151 of the ignition switch 170. Will be. Such a case will be described in detail later, but when the driver's authentication is completed by the electronic authentication device, the solenoid 230 is operated to separate the mover 210 from the receiving groove 151. When the occupant rotates the key 160, the steering lock changes to a state where the steering lock can be released.

One end of the lock pin stopper 330 is mounted with a spring 350 to transmit the elastic force. The spring 350 is preferably mounted in a compressed state, and when the actuator 200 does not operate, the lock pin 340 is inserted into the locking groove 126 by pushing the lock pin stopper 330. It's a good idea to keep them intact. In addition, in this state, since the mover 210 of the actuator 200 is inserted into the receiving groove 151 of the ignition switch 170 to prevent the rotation of the rotor 310, even if the driver rotates the key 160. The lock pin 340 is not separated from the locking groove 126.

As illustrated in FIG. 6, when the driver is located within a certain distance of the vehicle, a driving electric signal of the solenoid is generated from the electronic authentication device possessed by the driver, and the solenoid of the actuator 200 is generated. The solenoid 230 receiving the signal generates an electromagnetic force. Accordingly, the mover 210 of the solenoid 230 is reversed, and when the driver rotates the key 160, the cam protrusion 311 and the rotor 310 coupled to the ignition switch 150 rotate. Done. When the rotor 310 rotates, the cam 320 connected thereto rotates.

As the cam 320 rotates, the lock pin stopper 330 retreats in a straight line, and the lock pin 340 connected thereto is retracted to move away from the locking groove 126 formed in the steering shaft 125. Therefore, the steering shaft 125 is unlocked so that the steering shaft 125 is rotatable in accordance with the driver's handle operation.
