DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock device for a vehicle, which prevents a key from being locked in a vehicle during a keyless lock operation.

[0002]

2. Description of the Related Art Conventionally, a keyless lock operation of an automobile door (lock operation of a lock knob with the door open)
For example, an ignition key is a device that prevents the key from being locked into the vehicle when the door is closed from the outside of the vehicle without using the key by closing the door while releasing the outside handle. When the key is inserted into the cylinder and the door is opened, the key lock operation is performed in order to perform keyless lock operation. In order to prevent the lock mechanism from being locked, a block type in which the lock knob operation is blocked by the internal mechanism of the lock / unlock mechanism and an electric actuator connected to the lock / unlock mechanism are driven to forcibly unlock the lock / unlock mechanism. There is a return type that returns to the lock direction.

[0003]

However, the conventional device as described above has a problem that the structure of the door lock device is complicated in the former block type, and is also in the latter return type. Since the actuator for electrically locking and unlocking the locking and unlocking mechanism of the door lock device is driven when the above-mentioned state is attained, an actuator for locking and unlocking operation is provided. Unlocked door lock devices have a problem that cannot be set.

[0004] In view of the above problems of the prior art, the present invention provides a simple configuration for closing a key during a keyless lock operation even if the type does not include an actuator for locking and unlocking. It is an object of the present invention to provide a door lock device for an automobile which prevents the occurrence of a vehicle.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) An automobile door lock device including a meshing mechanism that can be disengaged from a striker, an unlock position that enables release of the meshing mechanism, and a knob lever that can be moved to a lock position that disables release. When the key is inserted into the ignition key cylinder and the door is in the open state, the electromagnet that is energized and generates a magnetic force and normally disengages from the engaging part formed on the knob lever and moves to the knob lever lock position. A stop lever that moves to a stop position that engages with the engagement portion of the knob lever by generating a magnetic force on the electromagnet and that prevents the knob lever from moving to the lock position. With
In addition, the stop lever is normally attracted to the electromagnet side to hold the stop lever at the release position, and when a magnetic force is generated in the electromagnet, the stop lever is held at the lock position by a repulsive force acting between the stop lever and the electromagnet. With a permanent magnet. (2) In the above item (1), the knob lever is divided into a first knob lever and a second knob lever, the first knob lever is provided on a lock knob provided inside the vehicle, and the second knob lever is provided on the outside of the vehicle. The second knob lever is connected to the key cylinder, and the second knob lever is formed with an engaging portion. Between the two knob levers, the two knob levers are constrained so that the two knob levers always move integrally with each other. When the stop lever prevents movement to the locked position, a spring is provided to bias both knob levers so as to allow the first knob lever to move independently.

[0006]

When the door is opened with the key inserted in the ignition key cylinder, the electromagnet is energized to generate a magnetic force. The stop lever moves to the stop position and engages with the knob lever engaging portion. Then, the knob lever is prevented from moving to the lock position, and the keyless lock operation is disabled.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. (1) shown in FIG. 5 is a door lock device provided on a door side of an automobile, and a striker provided on a vehicle body side.
(Not shown), a body (2) containing an engaging mechanism such as a latch (not shown) detachable from the latch and a locking plate (not shown) detachable from the latch, and a body (2) A cover plate formed of synthetic resin and provided with a locking and unlocking mechanism that controls the release operation of the meshing mechanism, which is provided on the back side of
An open lever (15) for releasing the locking plate is pivotally attached to the body (2).

As shown in FIG. 6, an outside lever connected to an outside handle provided on the outside of the door is provided on a flat portion (3a) of the cover plate (3) facing the body (2). (11) and a key lever (12) connected to a key cylinder provided on the vehicle outside of the door and moved to a lock / unlock position by a key operation.

An erecting surface which stands substantially perpendicularly from the flat portion (3a).
(3b) is connected to an inside handle provided inside the door as shown in FIG.
An inside lever (4) that contacts the arm portion (11a) of the outside lever (11) from below to move the outside lever (11) in a release direction (clockwise in FIG. 6);
Connected to the lock knob provided inside the door,
The first knob lever (5) pivoted by 4) and the end of the key lever (12) are coaxially pivoted with the first knob lever (5), and are inserted into a hole formed in the arm (6a). A second knob lever (6) connected to the key lever (12) and movable to a lock / unlock position integrally with the key lever (12), and a hole formed at one end;
(7b) is pivotally attached to the arm (11a) of the outside lever (11), and the long hole (7c) drilled at the other end is the second knob lever.
The sub-lever (7), which is slidably connected to the arm (6b) of (6) and moves between a locked position shown by a solid line in FIG. 1 and an unlocked position shown by a two-dot chain line, has one end (8a). The sub lever (7) is moved to the unlock position by contacting the opening lever (15) and the other end (8b) with the contact part (7a) of the sub lever (7) in conjunction with the door closing operation. A cancel lever (8) to be fixed and a permanent magnet (13) are fixed, and can be moved to a release position shown in FIG. 3 and a stop position shown in FIG. And an electromagnet (10) arranged at a position where the electromagnet is located. The locking / unlocking mechanism includes a first lever (5), a second knob lever (6), a sub lever (7), and a cancel lever (8).

Second knob lever (6) and cover plate (3)
A return spring (16) for holding the second knob lever (6) at a lock position and an unlock position by a predetermined urging force is provided between the first knob lever (5) and the second knob lever (6). A spring (17) having an urging force larger than the urging force of the return spring (16) is interposed between the first knob lever (5) and the second knob lever (6).
Can be integrally rotated to the locked position and the unlocked position.

The electromagnet (10) is energized by a coil to generate a magnetic force when a key is inserted into an ignition key cylinder for starting an engine and an ignition switch is turned on and the door is opened. It is generated, and otherwise controlled so as not to be energized.

When the key is not inserted into the ignition key cylinder and the door is in the open state, the lock knob is operated from the unlocked state to lock the first knob lever (5) and the second knob lever (6). Is rotated counterclockwise from the unlocked position shown in FIG. 4 to the locked position shown in FIG. 3, and in this state, the outside handle is released to operate via the outside lever (11). By closing the door while moving the contact portion (7a) of the sub-lever (7) out of the movement locus of the other end (8b) of the cancel lever (8), the movement of the cancel lever due to the door closing operation is lost. Thus, the first knob lever (5) and the second knob lever (6) are held in the locked position, and the door can be locked from outside the vehicle without using a key.

The stop lever (9) always has a permanent magnet (1).
At the release position where it is attracted toward the electromagnet (10) by the magnetic force of 3) and detached from the engaging portion (6c) formed on the second knob lever (6), the locked position of the second knob lever (6) The keyless lock operation is enabled by freely moving the key to the ignition key cylinder, but when the key is inserted into the ignition key cylinder and the door is open, the electromagnet (10) is energized to generate magnetic force. If there is a repulsive force between the electromagnet (10) and the permanent magnet (13), the stop lever
(9) is moved from the unlocked position of the second knob lever (6) by moving the (9) together with the permanent magnet (13) to the stop position engaged with the engaging portion (6c) of the second knob lever (6) by the repulsive force. The movement to the position is prevented so that the keyless lock operation cannot be performed.

The stop lever (9) is the second knob lever (6)
In the state where the second knob lever (6) is locked at the lock position, the lock knob is erroneously operated and the force in the direction of the lock position cannot be applied to the first knob lever (5). The spring (17) moves the first knob lever
The first knob lever (5) is flexed in the compression direction between (5) and the second knob lever (6) so that only the first knob lever (5) moves in the lock position direction, and the force applied to the lock knob is absorbed by the spring (17). No force is applied to the second knob lever (6), the second knob lever (6), the stop lever
(9) The deformation of the cover plate (3) and the like is prevented.

[0015]

As described above, the present invention can inexpensively prevent a key from being closed during a keyless lock operation even in a door lock device having no locking / unlocking actuator.

Also, since a repulsive force acts on the stop lever between the magnetic force of the electromagnet and the permanent magnet for holding the stop lever at the stop position, the stop lever can be reliably held at each position. Yes (claim 1).

Furthermore, since the knob lever is divided into first and second knob levers and a spring is provided between the two knob levers, the operating force of the lock knob at the time of erroneous operation can be absorbed, and deformation of other levers and the like can be prevented. (Claim 2).
