Abstract

PROBLEM TO BE SOLVED: To prevent a door lock device for vehicle from being illicitly operated from the outside of the vehicle. SOLUTION: A key cylinder member 1 comprises a body 2 and a lever 3. The body 2 is mounted on the door panel 4 of the vehicle, and each lower end of the flexible outer cord 10 and inner cord 11 of a wiring member 9 is connected to a latch member 6 for engaging and disengaging a door to/from the vehicle body, respectively. The upper end of the outer cord 10 is connected to the body 2, and the upper end of the inner cord 11 is connected to the lever 3, so that the outer cord 10 and inner cord 11 of the wiring member 9 are simultaneously bent, when the key cylinder member 11 is forcedly rotated down from the outside of the vehicle as shown by the two-dot chain line, to prevent the door locking state of the latch member 6 from being released.

Description

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 locking and unlocking a door of a vehicle with respect to a vehicle body, and more particularly to a door lock device for preventing unauthorized operation of the door lock device.

[0002]

2. Description of the Related Art In a conventional vehicle, a key cylinder is attached to a door panel, and the lever is rotated by operating the key cylinder with a key from outside the vehicle to connect a latch mechanism installed inside the door with the lever. The door is unlocked from the vehicle body by driving the latch mechanism via the rod.However, the key cylinder itself is forcibly displaced from outside the vehicle using an appropriate tool or the like, and the rod By driving the latch mechanism through the, there is a risk that the door may be unlocked illegally,
Even when the rod is replaced by a cable consisting of an inner cable and an outer cable, the inner cable can be displaced in the longitudinal direction with respect to the outer cable in a stationary state. By driving the latch mechanism with the inner cable, the door may be unlocked improperly.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to easily prevent an unauthorized operation of a door lock device in a vehicle from outside the vehicle.

[0004]

Therefore, a door lock device according to the present invention comprises a key cylinder member having a main body attached to a door of a vehicle, a key cylinder member having a lever which pivots downward by a key operation from outside the vehicle, and A flexible member comprising a latch member disposed inside the door below the key cylinder member and engaged with and disengaged from the vehicle body side, and an outer cable and an inner cable inserted through the outer cable and displaceable relative to the outer cable. And a lower end of the wiring member is connected to the latch member, an upper end of the inner cable is connected to the lever, and an upper end of the outer cable is connected to the main body. Have been.

Accordingly, the key cylinder member is forcibly displaced downward from outside the vehicle using an appropriate tool or the like, and the key cylinder member lever is displaced downward together with the body of the key cylinder member. Even when the distance between the latch members is reduced, the upper end of the inner cable of the routing member having the lower end connected to the latch member is connected to the lever of the key cylinder member, and the upper end of the outer cable is connected to the key cylinder member. Since the entire wiring member is bent, relative displacement does not occur between the inner cable and the outer cable, so that the latch member is not driven in the unlocking direction.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below. The key cylinder member 1 has a main body 2 and a lever 3. The main body 2 is attached to a door panel 4 of the vehicle, and the key cylinder portion 5 of the main body 2 is operated by a key from outside the vehicle. It is configured to rotate downward as shown in FIG.

The latch member 6 installed inside the door below the key cylinder member 1 has a main body 7 fixed to the door, while the lever 8 pivots downward as shown by the arrow B, so that the vehicle body The door to the side is unlocked.

Further, the routing member 9 disposed between the key cylinder member 1 and the latch member 6 can be displaced relative to the flexible outer cable 10 and the outer cable 10 through the outer cable 10, respectively. The upper end of the outer cable 10 is connected to the main body 2 of the key cylinder member 1, and the upper end of the inner cable 11 is connected to the lever 3 of the key cylinder member 1. The lower end of the cable 10 is connected to the main body 7 of the latch member 6, and the lower end of the inner cable 11 is connected to the lever 8 of the latch member 6.

A cover 12 attached to the main body 2 of the key cylinder member 1 completely surrounds the inner end of the main body 2 from above and from the side, and is arranged such that the ascending and descending door glass 13 does not interfere. I have.

That is, when the key cylinder portion 5 of the key cylinder member 1 is operated by a key from outside the vehicle, and the lever 3 is rotated downward as shown by the arrow A, the upper and lower ends of the key cylinder member 1 Main body 2 and latch member 6
In contrast to the outer cable 10 which is connected to the main body 7 of the key cylinder member 1, the inner cable 11 whose upper end is connected to the lever 3 of the key cylinder member 1 is displaced downward relative to the outer cable 10,
The lower end of the inner cable 11 connected to the lever 8 of the latch member 6 can rotate the lever 8 downward as shown by the arrow B to unlock the door with respect to the vehicle body.

On the other hand, as shown by the two-dot chain line in the figure, the key cylinder member 1 is forcibly turned downward from outside of the vehicle by using an appropriate tool or the like to unlock the door with respect to the vehicle body. In this case, the lower ends of the outer cable 10 and the inner cable 11 are respectively in a stationary state.
And the lever 8, the lever 3 of the key cylinder member 1 is also pivotally displaced downward together with the main body 2 of the key cylinder member 1, and the distance between the lever 3 of the key cylinder member 1 and the latch member 6 is reduced. The flexible outer cable 10 whose upper end is connected to the main body 2 of the key cylinder member 1
At the same time, the flexible inner cable 11 whose upper end is connected to the lever 3 of the key cylinder member 1 also bends similarly, so that no relative displacement occurs between the outer cable 10 and the inner cable 11, Therefore, since the lever 8 of the latch member 6 is not pushed down by the inner cable 11, the lock of the door with respect to the vehicle body is held without being released, so that unauthorized operation of the key cylinder member 1 is easily prevented. As a result, problems such as theft of the vehicle can be suppressed.

Since the cover 12 is attached to the key cylinder member 1, the door panel 4 and the door glass 1
3 can be reliably prevented from being tampered with, such as forcibly inserting a tool from above into the lever 3 so that the lever 3 of the key cylinder member 1 is pivotally displaced downward. Theft can be prevented.

[0013]

In the door lock device according to the present invention, even when the key cylinder member is forcibly displaced downward from outside of the vehicle using an appropriate tool or the like, the lower end portion is connected to the latch member. Since the upper end of the inner cable is connected to the lever and the upper end of the outer cable is connected to the main body of the key cylinder member, the relative displacement between the inner cable and the outer cable by bending the entire wiring member Does not occur, the latch member is not driven in the unlocking direction, so that unauthorized operation of the key cylinder member 1 can be easily prevented.
