Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection mechanism between a control handle and a conduction cable in a remote control device for an automobile door lock.

The remote control device for a door lock for an automobile shown in FIG. 1 consists of an operation section A in the driver's seat of the automobile, an intermediate connection section 81 between the vehicle body and the door, and a lock drive section C at the door.
The two vehicle side conduction cables e for transmitting motion to the left and right doors of the rear seat connected to the remote control handle d are connected to the vehicle floorboard r.
The connector g is connected to the hole in the vehicle body panel h through the connector g connected to the end through the lower part of the body panel, and the connector g is connected to the door side conductive cable at the hole in the door panel j through the intermediate protective connector i. One end is connected to the connector l holding it, and the other end to the door side conductive cable is connected to the bell crank lever m in the lock drive section C.

An indoor lock knob n is operatively connected to the bell crank lever m, and is also connected to a door lock p via an interlocking rod 0. The wires in the operating handle d through the conduction cable e are biased by a spring so that they automatically return to and hold a neutral position between the locking and unlocking positions.

In this configuration, when the driver tilts the remote control handle d of the operating section A forward from the neutral position, the bell crank lever m is rotated counterclockwise via its spindle by the conduction cables e and k, and the door is closed. The lock p is locked, and when it is tilted backwards from the neutral position, the bell crank lever m is rotated clockwise and unlocked.

On the other hand, by manually operating the indoor lock knob n up and down, the door lock p can be locked or unlocked via the bell crank lever m, and the door lock p can be locked or unlocked by the indoor lock knob n and the remote control handle d. The end of the door-side conductive cable is connected to the bell crank lever m via a play connection mechanism (not shown) so that locking and unlocking s5 can be performed independently.

The present invention provides a remote control device for an automobile door lock, including a remote control handle that rotates via a support shaft, a conduction cable connected to the handle and arranged in the direction of rotation of the remote control handle. The mechanism of the connecting part has been improved.

The conduction cable is composed of an outer tube made of a synthetic resin material such as polyethylene, and a wire made of steel that is slidably provided in the axial direction within the outer tube. The end of the outer tube is fixed to the vehicle body side, and the exposed end of the wire is attached to the operating handle which rotates via the support shaft by at least the amount of axial movement required for locking and unlocking operations from the outer tube. A configuration in which it is coupled at the intermediate portion is common.

By the way, in this configuration, the exposed portion of the wire comes into sliding contact with the end of the outer tube in a bent state when the remote control handle is rotated, so that the wire and the outer tube come into contact with each other in a bent state. This increases the frictional resistance between the terminals and increases the operating load, resulting in a lack of smooth remote control.

The present invention has been made in view of the above points, and includes a connecting rod that is exposed from the inside of the outer tube to the outside at the end of the wire, and a connecting rod that can rotate with the remote control handle. By connecting and supporting the end of the outer tube in a rotatable manner, the end of the outer tube follows the angular displacement of the connection port 7 with respect to the outer tube portion when operating the remote control handle. By sliding the iron smoothly against the outer tube part, the operating load in such remote control is reduced, and in particular, the automatic return movement of the handle or wire to its original position, that is, the neutral position, is ensured. It's just something.

An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIGS. 2 and 3, the remote control handle d has a channel-shaped frame 2 fixed to a base 1 fixed near the driver's seat of the vehicle through bolts 3 and nuts 4. Between the supporting plates 2a and 2b that are erected to face each other, the bottle 5 passes through the holes of the supporting plates 2a and 2b, and brings the folded W4 portion 5a into contact with the outer surface of the supporting plate 2a, and the other side 5b. The E-clip 6 protrudes from the support plate 2b and is secured by an E-clip 6. The bottle 5 passes through a hole at the lower end of a bifurcated remote control handle d and rotatably supports the handle d, and a handle 7 is provided at the upper end of the handle d.

On the outer periphery of the collar 8 placed on the bottle 5, there is a
A coiled spring 9 is installed to hold the motor in a neutral position. That is, the bent end 9a of the coiled spring 9 engages with the front surface 10a of the one side plate 10 of the bifurcated handle d, and also engages with the end surface of the movement permitting hole 2at protruding from the support plate 2a. The other bent end pb engages with the rear surface 11a of the other side plate 11 of the bifurcated handle d, and also engages with the end surface of the movement permitting hole 2b+ drilled in the support plate 2b, so that the four handles are closed during the locking operation. When the handle d is rotated forward (leftward in FIG. 2), the handle d restrains the bent end 9a of the spring 9 and stirs it through the movement allowance hole 2a+ without resisting the elasticity of the spring. When you release your hand, the handle d
is the second through the bent end 9a due to the restoring force of the spring 9.
Automatically returns to the neutral position shown in the figure. Handle d when unlocking
The operation when rotating in the t-14 direction (rightward in FIG. 2) is also the same as above.

The conduction cable e is an outer tube 12 made of a flexible synthetic resin material such as polyethylene.
