The operation of the start switch device is accomplished by using a start knob or an electronic start key, both of which eventually turn the key rotor to change the switch circuit. Therefore, the following description will focus on a method of operating the start switch by rotating the start knob.

4 is a state diagram of the start knob lock position.

The start switch is in the LOCK position when the driver is in the vehicle and the start knob or start key is not inserted. At this time, since the cam shaft 60 is in the LOCK rotational position and the solenoid actuator 91 is in the OFF position, the stopper plate 80 is inserted into the lock groove 51 by the elastic member 82, and The lock stopper 71 and the lock bar 77 are moved in the direction of the steering column by the elastic force of the lock spring 75, so that the steering column is in a steering lock state in which rotation is restricted by the lock bar 77.

5 is a state diagram of pressing the start knob in the start knob LOCK position.

When the driver rides in the steering lock state as described above and presses the start knob, smart communication is performed and the ID combination is approved. At this time, the solenoid actuator 91 is turned ON and releases the start knob lock state.

Here, as the solenoid actuator 91 is turned on, the locking pin 93 protrudes and presses the stopper plate 80, and the stopper plate 80 enters the inner side of the plate groove 72 to lock the stopper 71. And restraint of the lock bar 77 is released.

However, since the elastic force is provided by the lock spring 75, the lock bar 77 continues to maintain the steering column lock state.

6 is a state diagram of the start knob ACC position.

When the start knob is rotated to the ACC position in the LOCK position as described above, the lock stopper 71 and the lock bar 77 are moved upward in the drawing to release the steering lock state while the cam shaft 60 rotates. At this time, the solenoid actuator 91 continues to maintain ON operation.

Therefore, when the start knob is located in the ACC, the steering wheel of the vehicle is freely operated.

Fig. 7 is a state diagram of the start knob ON position, and Fig. 8 is a state diagram of the start knob START position.

When the start knob is rotated from the ACC position to the ON or START position, the cam shaft 60 rotates to the ON or START position, but the lock stopper 71 and the lock bar 77 adjust the position of the ACC state described above. The steering lock release state is maintained as it is.

At this time, the solenoid actuator 91 may be maintained in the ON operating state or switched to the OFF state.

9 is a state diagram in which the start knob is rotated from the ON position to the ACC position.

When the start knob is rotated from the ON position to the ACC position, the cam shaft 60 also rotates to the ACC position as described above, but the lock stopper 71 and the lock bar 77 maintain the steering lock release state. .

In particular, the solenoid actuator 91 is kept in the ON state, or is switched to the ON state in the OFF state.

10 is a state diagram in which the start knob is rotated from ACC to LOCK.

As described above, when the start knob rotates from the ACC position to the LOCK position again, the cam shaft 60 rotates to the LOCK position to release the lock stopper 71 and the lock bar 77 from restraining the lock spring. The lock stopper 71 and the lock bar 77 try to move downward in the drawing due to the elastic force of the 75. However, since the solenoid actuator 91 is in the ON operation state, the lock pin 93 protrudes It is inserted into the holding groove 74 of the stopper 71 to limit the movement of the lock stopper 71 and the lock bar 77.

Accordingly, the steering lock state is maintained in the pre-start state as shown in FIGS. 4 and 5, but as shown in FIG. 10, the steering lock release state is maintained when the start knob is switched back to the LOCK position from an ACC or higher position. Unauthorized column locking, which leads to an unwanted steering lock state, is prevented.

11 is a column lock state diagram at the start knob LOCK position.

If the driver opens the door, the smart key is out of the vehicle, the electronic ignition key is pulled out of the key box housing 50, the driver is not willing to drive the vehicle and a condition occurs where steering lock operation will occur, It outputs a signal to the solenoid actuator by communication.

At this time, the locking pin 93 is released from the holding groove 74 while the solenoid actuator 91 is turned off, so that the lock stopper 71 and the lock bar 77 are moved by the elastic force of the lock spring 75. As the lower side is lowered, the lock bar 77 is also lowered at the same time to constrain the steering column is switched to the steering lock state to limit the steering wheel operation of the vehicle. In addition, since the stopper plate 80 is locked to the lock groove 51, the start knob is also locked.

The manual shift vehicle steering lock apparatus using the electronic key according to the present invention constructed and operated as described above is provided with a solenoid actuator controlled by electronic communication, and has a start switch lock and release function, and the driver's will in the LOCK state. It is designed to prevent the locking bar from protruding and restrain the steering column irrespective of the structure, so the structure of the whole system is simple, and the reliability and convenience of the system operation structure can be increased. There is an advantage to improve the stability.
