BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for an automobile door, and more particularly, to a central locking device for an automobile door that enables the central locking control of the door to be performed at a passenger side door.

As shown in FIG. 1, the central locking device of a conventional car door is installed on a door of a driver's seat and selects a contact for central locking and releasing of the door using an ignition key. It consists of the switch 10, the control unit 20a, the first relay 20b and the second relay 20c and controls the overall operation of locking or releasing the door according to the contact selection signal of the first switch 10. The central control unit 20 and the actuator 30 for performing an operation for the central locking or unlocking of the door in accordance with the signal applied from the central control unit 20.

As described above, the central locking device of the conventional car door b uses the ignition key to close the contact point of the first switch 10 installed on the door of the driver's seat when the driver wants to lock the door of the car which has traveled to a predetermined destination. If it is selected, the control unit 20a of the central control unit 20 detects a signal applied from the first switch 10 and applies a predetermined signal to lock the door to the first relay 20b side. The first relay 20b controls the locking and unlocking of the passenger seat side door by applying the power of the battery BA to the actuator 30 by connecting the contacts through the electromotive force inside according to the signal applied from the control unit 20a. The first actuator 30a and the second and third actuators 30b and 30c which control the locking and unlocking of the rear seat side doors perform the door locking operation by the power applied from the battery BA.

In addition, when the driver wants to unlock the car door and selects a contact point of the first switch 10 installed in the driver's side door by using the ignition key, the control unit 20a of the central control unit 20 switches the first switch. According to the signal applied from (10), a predetermined control signal is applied to the second relay 20c side. The second relay 20c applies the power of the battery BA to the actuator 30 by connecting a contact point through internal electromotive force according to an applied control signal, so that the first actuator 30a and the second actuator ( 30b) and the third actuator 30c unlock the door by the power applied from the battery BA.

As described above, the locking device of the conventional vehicle door is capable of central locking control only at the driver's side door, so the driver moves to the driver's side in order to realize the central lock control when the driver gets off using the driver's side door due to the narrow parking space. There is a problem because it has to be, there was a problem that the central lock control of the door is not realized through the passenger side door.

The present invention has been made in view of the above-described problems, the object of which is to provide a convenience in the central locking control of the door by the central locking control of the door can be performed in the passenger side of the door, and narrow the parking space or other When it is impossible to open and close the driver's door due to the reason it is to provide convenience for the driver and passengers riding on the passenger.

A feature of the present invention for achieving the above object is a lock of the vehicle, the first switch is installed in the door of the driver's seat side and the contact point for the central locking and unlocking of the door by the ignition key, the control unit and the first A central control unit comprising a first relay and a second relay, and an actuator for performing an operation for the central locking or unlocking of the door in accordance with a signal applied from the central control, which is installed on the passenger side door and the door by the ignition key The second switch, the contact for selecting and locking the center of the switch is selected, and the signal applied through the selection contact of the first switch and the signal applied through the selection contact of the second switch to perform a logical sum of a predetermined signal It provides a central locking device of the vehicle door characterized in that it further comprises a first, second logic means for outputting.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a central locking device for a car door according to the present invention.

As can be seen in the figure, the present invention includes a first switch 10, a central control unit 20, a control unit 20a, a first relay 20b, a second relay 20c, a first actuator 30a, The second actuator 30b, the third actuator 30c, the fourth actuator 30d, the second switch 40, the first gate 50, and the second gate 60, the first switch ( 10) is installed on the door of the driver's side and outputs a predetermined signal for central locking or unlocking of the door by selecting a contact using an ignition key. The second switch 40 is installed on the passenger side door and outputs a predetermined signal for center locking or releasing the door by selecting a contact using an ignition key. The first gate 50 performs a logic sum operation on the signals applied from the first switch 10 and the second switch 40 to output a predetermined signal. The second gate 60 performs a logical sum operation on the signals applied from the first switch 10 and the second switch 40 to output a predetermined signal. The central control unit 20 includes a control unit 20a, a first relay 20b, and a second relay 20c, and the control unit 20a is applied to the first gate 50 or the second gate 60. Detects and analyzes a signal of the control panel and outputs a predetermined control signal for centrally locking or releasing the door. The first relay 20b interrupts an internal switching contact for performing the central locking operation of the door according to a signal applied from the controller 20a and applies the power of the battery BA to the actuator 30. The second relay 20c intercepts the internal switching contact for performing the central lock release operation of the door according to a signal applied from the controller 20a and applies the power of the battery BA to the actuator 30. The actuator 30 locks or locks the first actuator 30a for executing the locking or releasing operation of the passenger seat side door, the second actuator 30b for locking or releasing the door on the left side of the rear seat, and the door on the right side of the rear seat. A battery BA comprising a third actuator 30c for releasing and a fourth actuator 30d for locking or releasing the driver's side door and being applied through the first relay 20b or the second relay 20c. Forward or reverse rotation is performed by the power

Referring to the operation of the present invention made of the function as described above are as follows.

When the driving vehicle arrives at a predetermined destination and wants to lock the door through the central lock control, when the contact point of the first switch 10 is selected as b using the ignition key, the second gate 60 switches the first switch 10. A high level signal is applied to the high level signal applied through the contact of the second switch 40 and the low level signal applied through the b contact of the second switch 40, and the high level signal is controlled by the control unit 20a of the central control unit 20. To apply. The control unit 20a of the central control unit 20 outputs a predetermined control signal to the first relay 20b side according to a high level signal applied thereto, and connects the internal switching contact to the actuator. 30) is applied to the side. Therefore, the first actuator 30a of the actuator 30, the second actuator 30b, the third actuator 30c, and the fourth actuator 30d are rotated in a predetermined direction by a power source to which the door is locked. Run

On the contrary, when the door in the locked state is to be released, if the contact point of the first switch 10 is selected as a using the ignition key, the first gate 50 is applied through the contact point of the first switch 10. The high level signal is applied to the control unit 20a of the central control unit 20 by performing a logical multiplication on the signal of the level and the low level signal applied through the contact a of the second switch 40.
