At this time, there is no connection between the electronic key 100 and the transponder communication module in the holder 200, and performs a simple storage function that does not affect the emergency start of the vehicle.

Emergency start mode

5 to 9 show the operating relationship of the locking means 270 in the emergency start mode of the present invention.

First, as shown in FIG. 5, in the first stage locking state, the cam pin 248 protruding from the bottom of the inner case 240 is positioned at the front center of the cam 271.

Then, if the driver continues to push the electronic key 100 in the entry direction by applying a force to switch from the key storage mode to the emergency start mode, the electronic key 100 is to push and move the inner case 240, The cam pin 248 protruding from the bottom of the inner case 240 is in contact with the cam 271 of the locking means 270.

At this time, the cam 271 is shaft-fixed in a state in which one end is rotatable, and the front inclined portion 271a is formed at the other end extending from the fixed shaft to the inner case 240 in the advancing direction. The cam 271 is axially rotated by the interference by the cam pin 248.

Here, the cam 271 is rotated along the inclined direction of the front inclined portion 271a.

Subsequently, as the inner case 240 continues to move forward as shown in FIG. 6, the cam pin 248 enters the side straight portion 271b out of the front inclined portion 271a.

At this time, the inner case 240 is approaching the maximum limit point that can not move any further, when the driver releases the electronic key 100, the pushing force is removed and at the same time the repulsive force of the inner case spring 243 As a result, a force that the inner case 240 tries to return in the opposite direction to the entry is applied.

Accordingly, the cam pin 248 is backed in contact with the side straight portion 271b, but is caught in the rear jaw of the front inclined portion 271a, so that it is no longer possible to reverse. At this time, the cam 271 is a state in which the restoring force is applied by the cam spring 273 coupled to the center of the rotation shaft, and the cam pin 248 is guided into the locking groove 271c while rotating clockwise as shown in FIG. 7. Be sure to

At this time, the locking groove 271c is a curved groove formed laterally toward the center of the body of the cam 271. When the cam pin 248 is positioned at the curved vertex, the cam 271 rotates. It is stopped, and the retraction operation of the inner case 240 is stopped, and the two stage locking state is stopped.

This is a state in which the rotational force of the cam 271, that is, the restoring force of the cam spring 273 is suppressed by the force of the inner case spring 243, and the ground terminal 246 formed on the inner case 240 is the PCB substrate 250. By operating the switch 253 installed in the) is an electrical signal is possible.

That is, as the electronic key 100 and the transponder communication module in the holder 200 are connected, emergency starting of the vehicle becomes possible.

Subsequently, when the driver wants to release the two-stage locking state, the pressure of the inner case spring 243 that has suppressed the rotation of the cam 271 by slightly pushing the electronic key 100, that is, the inner case 240, is removed. Be sure to

As the spring pressure is removed, the cam 271 continues to rotate clockwise, and as shown in FIG. 8, the cam pin 248 moves out of the locking groove 271c and enters the slit groove 271d.

The slit groove 271d is a space formed in the center of the body of the cam 271 in the longitudinal direction, and forms a space in which the cam pin 248 is retracted after a predetermined distance is moved by the driver's pressing force.

When the driver removes the force to press the electronic key 100, the inner case 240 is retracted by the elasticity of the inner case spring 243, the cam pin 248 is retracted along the slit groove 271d and the cam 271 enters the leaving groove 271e formed in the body.

At this time, when the cam pin 248 enters the escape groove 271e, the cam 271 is in a state of being lifted up with the rotation axis as a starting point, and the cam spring 273 restores the cam 271 to the rotation axis direction. The elastic force to be acted on. The elastic force at this time serves to reduce the return speed of the inner case 240 by providing a friction force between the separation groove (271e) and the cam pin 248, which has the advantage of smoothing the feel.

The cam pin 248 which has escaped from the leaving groove 271e returns to the position of the one-step locking state as shown in FIG.

According to the present invention having the above-described configuration, the door 231 is formed at the inlet of the electronic key holder 200 of the vehicle to prevent foreign matter from penetrating, thereby making it beautiful in appearance and preventing failure due to foreign matter infiltration.

In addition, by mounting the electronic key 100 in a holder and safely storing it normally, the risk of losing the electronic key 100 can be reduced, and the electronic key 100 is operated to be locked in two stages. It can be divided into modes, and even when returning from the emergency start mode to the key storage mode, the smooth operation is possible by the one-touch method, thereby satisfying the user's convenience.
