Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention adjusts the length of a wire cable provided in an actuator of an automobile lock that can unlock an automobile trunk door or a gas tank cap lid. This invention relates to a length adjustment device for automobile wire cables.

Conventionally, when unlocking a car, an operation switch installed near the driver's seat is closed, and a motor or solenoid is driven to drive a wire cable. The engagement is designed to be disengaged.

[Problem that the invention seeks to solve]

For example, when installing a drive member to release the lock from the driver's seat to the trunk door, door, or gas tank door, the wire cable must be made long, so this wire cable may be When the wire cable is bent, the contact between the outer tube of the wire cable and the wire inserted into the outer tube increases the load due to frictional resistance. Therefore, when driven by a motor or solenoid, the wire is The disadvantage is that it does not slide smoothly, which hinders the operation when releasing.

[Means for solving the problem 17] In order to eliminate this drawback, the object of the present invention is to provide an A-adjusting nut for appropriately adjusting the length of the outer tube of the wire cable in the drive device that drives the wire cable. After installing and arranging the wire cable, rotate this nut to minimize the bending of the wire cable and reduce frictional resistance.

[For production]

Install the trunk door, door opening,
One end of the engaging rod of the first wire cable for the trunk, which is connected to a release member (not shown) for releasing the rack member, is locked, and the other end of the rack member is provided with a gasoline tank cover, The gas tank cover is linked with a release member (not shown) for releasing the locking mechanism, and the engagement lever of the second wire cable for the locking mechanism is locked, and the first wire cable and the second wire cable are connected to each other. A pipe is fixed to the outer pipe of either one of the engaging rods, and a screw is carved into the outer peripheral wall of this pipe,
An adjustment nut is screwed onto this screw, and the length of the outer tube is adjusted by rotating the nut.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In the drawings, FIG. 1 is a side view of the driving member, with a part of the outer wall 1 of the case body cut away. FIG. 2 is a longitudinal sectional view of FIG. 1, FIG. 3 is a diagram of the rack member in operation, and FIG. 4 is a perspective view of the rear of the automobile. FIG. 2 is a perspective view showing a drive member mounted on a rear wall edge 2b of a central portion 2m of FIG.

In FIG. 1, when the remote control switch 8W near the driver's seat is closed, the drive motor 3 for forward and reverse rotation in the drive member is driven, and at the same time, the rotation shaft 31 of the motor 3 is driven.
The binion 4 provided on L is meshed with the binion 5a on the peripheral edge of the crank gear 5, and the binion 71L on the peripheral edge of the super gear T is meshed with the pinion 6 provided on the rotating shaft 5b of the crank gear 5. and rotate this super gear 7. Rotating shaft 7b of this super gear 7
A rack member 12 is provided which meshes with the binion 8 provided at the side and the rack 9 on the side edge and slides to either the left or right in the notch groove 11 of the case body 10 when the motor 3 is driven.

A rectangular stepped portion 12' is formed on the rack member 12,
The wire 131L in the first wire cable 13 for releasing the opening for the trunk lid 2 (not shown) is inserted into the insertion hole 10' formed in the case body 10, and the wire 131L of the first wire cable 13 is inserted. Engagement rod 1 fixed to one end
3' is fitted into the stepped portion 12' of the rack member 120, a retaining part 14 is formed at the tip of the rack member 120, and the wire 131
In addition to preventing the L from being pulled out, the end 14 of this locking part 14
& is locked to the stepped portion 14b formed on the case body 10,
The rack member 12 is held at the neutral position at. A spring (not shown) is fitted to the other end of the first wire cable 13 to urge it when the rack member 12 returns to the neutral position t after the rack member 12 has moved 1-.

Further, a gasoline tank cap lid 2 is provided at a position facing the first wire cable 13 and moves in opposite directions with respect to the first wire cable 13.
0 side second wire cable 16 and an engagement rod 18b provided at one end of the wire 161L of this second wire cable 16
is secured to the stepped portion 12' of the rack member 12, and a pull-out portion 160 is formed at the tip thereof.The pull-out portion 160 prevents the second wire cable 16 from being pulled out, and the end of the pull-out portion 16G A stepped portion 14 formed on the case body 10
b to hold the rack member 12 at the neutral position t. Further, a spring (not shown) is fitted to the other end of the second wire cable 16 to return the rack member 12 to the neutral position after the rack member 12 has been moved.

Notch recess 17°IT' for mounting on both sides of case body 100
is provided and attached to the trunk lid 2.

After installing the trunk door 2 in this way, in order to make the length of the first wire cable 13 or the second wire cable 16 adjustable, either one of the first wire cable 13 or the second wire cable 16 is attached. A pipe 18 is fixed to the collapsed portion of the outer tube 13b, a screw is carved into this pipe 18, and a rotatable nut 19 is fitted into the notch groove 10& of the case body 10, and this nut 19 screw onto the vibrator 18.

As a result, when the nut 19 is rotated, the outer tube 1
3b is moved to adjust the length of the outer tube 13b.

〔Effect of the invention〕

As described above, according to the present invention, the length of the outer tube of the wire cable can be freely adjusted. For example, when the wire inside the outer tube is shortened, the length of the outer tube can be shortened using the adjustment nut. Since the length of the outer tube and the wire can be precisely matched, the wire slides smoothly when the drive member is driven, and a reliable release operation can be achieved.
