Description

Door lock device of car

The present invention relates to a door lock device for a vehicle, and more particularly, to a door lock device for a vehicle so that the lock of the vehicle can be released only by entering a password with a remote control device.

The door lock device of a typical automobile is shown in FIG. As shown in FIG. 1, the inner handle 30 and the outer handle 40 by the door lock assembly 10 for limiting and fixing the movement of the door and the connecting rod 20 for opening the lock of the door lock assembly 10. ) Is connected. In addition, the door lock assembly 10 is connected by the cylinder lock 50 and the ball crank 60 for opening and closing the door by inserting a key. And the ball crank 60 is connected to the knob 80 which is a push button via the knob link 70, the door lock assembly 10 is an automatic door lock actuator 90 for releasing the door lock using the power of the motor. Is connected. The automatic door lock actuator 90 is connected to each door to simultaneously open and close the door.

In the door lock device made as described above, the lock ratchet portion of the door lock assembly 10 contacts the striker portion of the vehicle body so that the lock ratchet portion is rotated and locked to limit the movement of the door. In order to release or maintain the locked state, the knob 80 is up / down or the key is inserted into the cylinder lock 50 to release / maintain the locked state. In addition, the door can be opened by pulling the inner handle 30 or the outer handle 40 after the locked state of the door, but only pulling the handle or the outer handle 40 when the door is locked. You cannot open the door with it. As described above, in order to release the locked state of the door, if the knob 80 is up / down indoors, it can be released by inserting it into the cylinder lock 50 through the key if possible outdoors.

By the way, a number of vehicles are manufactured and sold, but because the keys of the vehicle are supplied in a limited manner, not only are there many keys, but also many cases where the door lock can be released by manual keys or mechanical keys. The vehicle is at risk of theft.

Accordingly, the present invention has been made to solve the problems in the prior art as described above, the object of the present invention even if the key is a door lock device of a vehicle so that the door lock can not be released without entering the password by the remote controller To provide.

The present invention for realizing the above object is connected to the ball crank through the knob for maintaining or releasing the locked state of the door, and the knob link to transfer the action of the knob up / down and the crank is connected to the door lock assembly A door lock device configured to be connected to maintain or release a lock of a door, the door lock device comprising: a bracket fixed to a knob link connecting a knob and a ball crank to hold or release a lock of the door, and to be detachably coupled to the bracket. And an actuator fixedly mounted to the vehicle body, a controller for controlling the operation of the actuator, and a transmitter for operating the controller at a remote location.

When explaining the operation by the configuration described above, if the password for operating the controller at the remote transmitter inputs the password to determine whether the match, the controller operates the actuator to separate the actuator coupled to the bracket to match the The door lock can be released arbitrarily.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and the same parts as in the conventional configuration using the same reference numerals and names.

2 is a view showing a configuration of one side door of a vehicle equipped with a door lock device according to the present invention. When mounted on an actual vehicle, an actuator 110 connected to one controller 120 is installed in each door. .

First, look at the configuration of the door lock operating by mounting the door lock device according to the present invention, the knob 80 for maintaining or releasing the locked state of the door, and the knob link for transmitting the action of up / down of the knob 80 ( 70 is connected to the ball crank 60 and the crank 60 is connected to the door lock assembly is configured to maintain or release the lock state of the door. In addition, in order to maintain or release the lock state of the door from the outside, the lock state of the door is maintained / released by inserting a key into the cylinder lock 50 connected to the ball crank 60. The bracket 100 is fixedly installed on the knob link 70 and the actuator 110 is fixedly mounted to the door to be coupled / separated from the bracket 100. The control unit 122, which receives the signal transmitted from the remote site and compares or determines the same data as the stored password, is electrically connected to the actuator 110 to control the operation of the actuator 110, and transmits the password from the remote site. It consists of a transmitter 130.

Referring to Figure 3 as a configuration for showing the gist of the present invention well fixed to the bracket 100 to the knob link 70 to move up and down, the bracket 100 is coupled to the removable ring structure The actuator 110 is fixedly mounted in the door, and the control unit 122 and the control unit 122 are electrically connected to the receiving unit 124 which receives a signal transmitted from a remote location to control the operation of the actuator 110. do. It also consists of a transmitter 130 for transmitting a password from a remote location.

In order to explain the operation of the present invention will be described in detail with reference to a flow chart showing the operating sequence of FIG. In the present invention, when the door is locked, the actuator 110 is automatically coupled with the bracket 100 to maintain the locked state. Therefore, the control method of the actuator 110 provides two functions. One provides a function for releasing the door lock state and the other provides a function for temporarily placing the operation of the actuator 110 temporarily.

First, as a function for releasing the door lock state, the door state is compared with the lock state, and when the locked state is compared with whether the data, that is, the password is input from the remote transmitter 130. If a password is input, the input data is compared with the password recorded in the control unit 122, and if it matches, the actuator 110 is operated to release the coupling state of the actuator 110 and the bracket 100 in general means, The door lock state can be released by pulling the key and the knob 80.

Next, to temporarily stop the operation of the actuator 110 during a temporary parking stop, when the door is not in the locked state, a signal is input from the remote transmitter 130 to temporarily stop the operation of the actuator 110. In the case of a signal, the operation of the actuator 110 is temporarily stopped, and even if the door is locked, the actuator 110 is not operated so that the door lock state can be released only by the key.

As described above, the present invention can release the door lock state only by remote control, thereby preventing theft of the door lock state due to similar keys, universal keys, machine keys, manual work, and the like.
