Abstract

PURPOSE: An apparatus for preventing door-locking of an automobile is provided to prevent a door locking device from being operated while the ignition key is inserted into a key hole. CONSTITUTION: The apparatus includes a key set(1), an electric circuit part(4) which activates an electromagnetic solenoid(2) in response to the insertion of the ignition key, and a locking device(8) for preventing locking of the door lock in response to activation of the solenoid(2), which is mechanically connected with a door lock nob(6) through a connecting bar(6a), a compression spring(7) and a movable arm(5). The movable arm(5) has a guide groove(5b) extending from an aperture(5a) which passes the connecting bar(6a). When the solenoid(2) is activated, the movable arm(5) moves toward the solenoid(2) so that the connecting bar(6a) is inserted into the guide groove(5b), thereby restraining downward movement of the door lock nob(6).

Description

A LOCKING PROTECTING DEVICE OF DOOR OF A CAR}

The present invention relates to a lock preventing device for an automobile door, which prevents the door from being operated when a key is placed on a key set of an instrument panel inadvertently by a driver. It relates to a lock preventing device of the car door that is provided so that the locking device is not driven.

In general, a car is provided with a door installed in a passageway where a passenger rides and disembarks.In order to get on a vehicle, a driver pulls an outer handle provided at the outside of the door to board a driver's seat and an inner handle provided at the inner panel of the door. Pull to close the door, and when getting off, the handle provided on the inner handle is pulled to release the locking device of the door to open the door and then get off and close the door.

Here, the door is provided with a locking device to the inside of the door panel in order to maintain the safety of the occupant and the security of the vehicle, the door lock knob is provided by pressing the door lock knob provided on the top of the inner panel of the door when the driver gets off After operating and getting off the door to close the door is to be locked.

Meanwhile, in order to open the locked door, the car key is inserted and rotated into a key insertion groove provided in the outer panel of the door, thereby allowing the door lock knob to protrude to its original state and operating the locking device located under the door lock knob. To open the door.

However, as described above, the driver presses the door lock to operate the locking device to close the door and inserts a key into the key insertion groove of the outer panel to release the locking device. When the driver presses the door lock knob to activate the lock with the key inserted in the key set on the instrument panel, and closes the door under the disembarkation, the driver who locks the door unlocks the door window to release the lock. Inserting a means such as a wire between the gap of the to release the locking device provided in the interior of the door panel there was a problem that damage to the vehicle body during this process.

Accordingly, the present invention has been made in order to solve the above problems, the object of the present invention is to provide a lock preventing device for a car door in which the locking device of the door is not operated when the driving key is inserted into the key set on the instrument panel. There is this.

1 is a configuration diagram showing an operating state of the lock preventing device for a vehicle door according to the present invention.

In order to achieve the above object, the present invention provides a key set comprising a key insertion groove into which a driving key is inserted, a spring provided on the left and right sides of the key insertion groove, and a ball on which one end of the spring is pressed, and the key. A circuit part comprising a set, a power supply, and an electromagnet, and a locking part configured to restrict the downward flow of the door lock knob by being composed of a spring and an opening / closing arm which flows toward the electromagnet according to the driving of the electromagnet.

Accordingly, when a key is inserted into the insertion groove of the key set, an electromagnet of the circuit unit is provided and the opening and closing arm is pulled toward the electromagnet to prevent downward movement of the door lock knob driving the door lock.

This prevents the door from being locked in the state where the key is flowered on the key set.

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

1 is a configuration diagram showing the operating state of the lock device of the vehicle door according to the present invention, the driving key is inserted into the key insertion groove (1a) and the left / right side of the key insertion groove (1a) is provided drive key When the ball is inserted into the key insertion groove (1a) of the ball (1b) to be in contact with the inserted drive key and the ball (1b) is connected to one end and the other end of the power source (3) and electromagnet (2) and A key set 1 composed of a spring 1c connected to each other via an electric wire, a arc part 4 which is a closed circuit composed of the key set 1, an electromagnet 2 and a power source 3, and the electromagnet (2) Pressurized spring (7) and the door which is pressed by the opening and closing arm (5) flowing toward the electromagnet and the opening and closing arm (5) in accordance with the opening of the circuit portion in accordance with the drive of the (2) The lock part 8 which consists of a door lock knob 6 which drives the door lock provided in the inside of a panel is comprised.

Here, a connection table 6a connected to the door locking device provided inside the door panel is formed under the door lock knob 6 of the locking unit 8.

In addition, the opening and closing arm 5 of the locking portion 8 is an insertion groove 5a open to a predetermined size so that the door lock knob 6 is inserted, and formed to the right side of the insertion groove 5a and connected to the connection table 6a. Is inserted into the guide groove (5b) of the straight-shaped guide groove (5b), the left end of the opening and closing arm 5, the insertion end (5c) and the opening and closing box (5) to be inserted into the inside of the pressure spring (7) Therefore, it consists of a pressurizing end 5d which pressurizes the press spring 7 inserted in this insertion end 5c.

Therefore, when the driving key is inserted in the key insertion groove 1a of the key set 1, the electromagnet 2 of the circuit portion 4 composed of the key set 1, the electromagnet 2 and the power source 3 is driven. The opening and closing arm 5 provided on the right side of the former magnet 2 flows toward the electromagnet 2 while pressing the pressure spring 7, and the door lock knob of the guide groove 95b of the opening and closing arm 5. 6) toward the connecting rod 6a.

In addition, when the key is released from the key insertion groove 1a of the key set 1, the wing circuit portion 4 is opened and the opening / closing arm 5 flowing toward the electromagnet 2 is applied to the elastic force of the pressure spring 7. While being positioned in the win position, the connecting rod 6a of the door lock knob 6 is positioned inside the insertion groove 5a of the opening and closing arm 5.

Therefore, when the driving key is inserted into the key set 1, the connecting rod 6a of the door lock knob 6 is positioned inside the guide groove 5b, so the downward flow of the door lock knob 6 is guided. The door lock is restricted by the left / right surface of the groove 5b, and the circuit part 4 of the door lock knob 6 is located in the insertion groove 5a in the state where the driving key is released from the key set 1. Up / down flow of the knob 6 is to be made in the space of the insertion groove (5a).

Accordingly, since the door lock knob 6 in which the key is inserted into the key set 1 is not pressed, the locking device provided in the door panel is not driven so that the driver inserts the key into the key set 1. This prevents the door from locking.

As described above, according to the present invention, the connecting rod 6a at the bottom of the door lock knob 6 is inserted into the insertion groove 5a of the opening and closing arm 5 for controlling the downward flow of the door lock knob 6. Since the downward movement of the door lock knob 6 is restricted when the key is inserted into the key set 1, the door is not locked when the driver inadvertently flowers the driving key in the key insertion groove 1a. It is effective.
