Description

Car door lock

The present invention relates to an automobile door locking device, and more particularly, to an automobile door locking device for installing a door locking device on a center pillar to prevent theft of an automobile and allowing the door to be unlocked or corrected according to whether a sensor is detected. .

In general, the vehicle door lock device has a built-in locking device interlocking with the key cylinder, and is configured to correct or unlock the door by rotating the key after inserting the key in the key cylinder.

For example, in the conventional door locking device, as shown in FIG. 1, the locking lever 10 may be rotated to obtain a state of locking or unlocking, and the position switch 11 may unlock the locking lever 10 in the locked position. Detect if you are in position. The door lock switch 12 detects whether the locking mechanism is in a locked state or in an unlocked state.

In addition, the locking lever has a current that flows through the door lock motor 13 to rotate forward or reverse to move it, or to insert the key into the door key cylinder 14 to move manually and to move the door lock knob 15 in the room. It is configured to be operated by any one of the methods. In the drawing, reference numeral 16 denotes a door key.

However, such a configuration can be unlocked by inserting a tool because the door lock is installed in the door, which may cause theft.

As a solution to this problem, there has been suggested an anti-theft system that uses a security device that generates a warning sound or stops the vehicle's driving function when attempting to break into the vehicle by illegal means. You can, but there is a problem that can not prevent theft.

The present invention has been made to solve such a problem, in particular, the door lock is installed in the center pillar and the detection means and the actuator for interlocking the door to interlock in the vehicle by making it impossible to unlock the door by inserting tools, etc. It is an object of the present invention to provide a door lock device for preventing theft or theft.

In order to achieve the above object, the present invention provides a door lock having a key cylinder, and a handle detecting sensor for detecting a grip state of an outside handle and a unlocking / correcting state of a key cylinder. A lock sensor, a detection sensor for detecting an electrical connection state between the unlock / lock detection sensor and a microcomputer, and whether the detection sensors are electrically connected and outputting a control signal for driving the door locking device. And a door lock device for locking / unlocking the door according to the driving of the actuator and the microcomputer, an actuator for driving and unlocking the door according to the control signal of the microcomputer.

According to this configuration, when the door is locked, the key is inserted into the key cylinder and the lock / unlock sensor is short-circuited when the switch is turned to the locked position. Afterwards, the lock does not operate even when the outside handle is operated. The door lock is activated by the connection of the unlock / lock sensor only when the outside handle is operated after the switch to the release lock after insertion into the key cylinder.

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

Figure 2 is a block circuit diagram showing a door locking device of the present invention, the door portion 100 is provided with a conventional key cylinder, the center pillar 200 is provided with an actuator and a door locking device. The actuator is driven by the control signal of the microcomputer to correct or unlock the door locking device.

The door locking device of the present invention installed as described above has a handle detection sensor 110 for detecting a grip state of the outside handle and an unlock / lock detection sensor 120 for detecting an open / closed state of a key bundle inside the key cylinder. Installed in the door part 100, the center pillar 200 also includes an actuator 210 driven by a control signal of the microcomputer 300 and a known or corrected door according to the driving of the actuator 210. By installing the door lock device 220 so that tools, etc. can not be inserted to prevent intrusion and theft in the car in advance.

In addition, a detection sensor 130 is installed between the door unit 110 and the center pillar 200 to detect an electrical connection state between the unlock / lock detection sensor 120 and the microcomputer 300.

In the present invention configured as described above, the key is inserted into the key cylinder as shown in the flowchart of FIG. 3 to determine the rotation state of the key bundle, that is, the open / close state of the key bundle through the unlock / lock detection sensor 120.

For example, when the door key bundle is switched to the closed state, since the unlock / lock detection sensor 120 is short-circuited, the microcomputer 300 and the unlock / lock detection sensor 120 may be operated even when the outside handle is operated. Is electrically shorted and the door is not opened.

On the contrary, when the door key bundle is switched to the open state, the unlock / lock detection sensor 120 is connected, and when the outside handle is operated in this state, the handle detection sensor 110-the unlock / lock detection sensor 120-the microcomputer Since the 300 is electrically connected, the microcomputer 300 is driven by supplying power to the actuator 210, and at the same time, the door locking device 220 is released.

As described above, the present invention makes it impossible to insert a tool by installing a door locking device on the center pillar, and also provides a safety device for unlocking the door only when electrical connection of each sensor is possible when the door is unlocked. There is an effect that can be prevented.
