The movable block 12 is provided with a nut screw-coupled to the screw shaft 7 and a through hole slide-coupled to the guide shaft 5 . Accordingly, when the screw shaft 7 rotates, the movable block 12 moves linearly along the screw shaft 7 , and sliding occurs between the guide shaft 5 and the movable block 12 . In order to facilitate sliding, a bush-type oilless bearing may be further provided in the through hole coupled to the guide shaft 5 .

The push bar driving means includes a servo motor 11 fixed to the movable block 12 and moving together with the movable block 12 , and a pinion 13 coupled to a drive shaft 23 of the servo motor 11 . consists of including In fixing the server motor 11 to the movable block 12 , a separate fixing member 10 may be used.

The push bar 17 may be formed in a bar shape having a rectangular cross section, and a car key ( Install so that it faces the operation buttons (B1~B4) of K). In addition, the push bar (17) has a rack portion (19) meshing with the pinion (13) is formed at the rear of the upper surface. By doing this, when the pinion 13 is rotated by the servo motor 11, the push bar 17 can protrude straight. At the rear of the push bar 17, one end is fixed to the rear end of the push bar 17 and the other end is provided with a restoration spring 21 fixed to the inner wall of the rear side of the push bar holder 15, so that the driving of the servo motor 11 is stopped. When done, the protruding push bar 17 can be returned to the push bar holder.

1 to 3 again, as can be seen, the present invention includes a controller 45 for controlling the key operation module 1 according to a user's remote wireless command. The controller 45 includes a PCB board 47 for the control circuit and a tact switch 49 for calibration for the movement range of the key operation module 1 . A cover 51 assembled to the case 27 may be provided, and the controller 45 may be assembled in the cover 51 .

The controller 45 is provided with a wireless communication module that can wirelessly receive the user's remote button operation command from the smartphone together with the encryption key, and when receiving the button operation command from the smartphone together with the encryption key, the corresponding button operation After moving the push bar 17 by controlling the moving means in front of the operation buttons B1 to B4 of the car key K corresponding to the command, the push bar 17 is moved to the corresponding button by controlling the push bar driving means. Press it by pushing it toward the

7, the controller 45 includes a step motor controller 118 for driving the step motor 11, a CAN communication module 110 for communicating with other electric devices of the vehicle, and A buzzer 112 for notifying a warning, etc., an LED 114 for indicating power or operation status, a Bluetooth module 102 functioning as a wireless communication module with the smart phone, and communication with an external device It may further include an interface 120 and a microcontroller unit 100 capable of controlling all of them. The server motor 9 may be directly PWM controlled by the microcontroller unit 100 .

The present invention can be driven by the power of the battery 37 . A battery accommodating part 35 for mounting the battery 37 may be provided in the case 27 .

The controller may further include a charging circuit 106 for charging the battery 37 and a DC converter 108 for adjusting the input DC voltage to the charging circuit input voltage.
