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 car door lock shown in Fig. 1 consists of an operating part A in the driver's seat of the car, an intermediate connection part B between the vehicle body and the door, and a lock drive part C in the door, and a remote control handle d. The two vehicle body-side conduction cables e for transmitting motion to the left and right doors of the connected rear seats are connected to holes in the vehicle body panel h via connectors g connected to the ends through the lower part of the vehicle floor plate f. , the connector g is connected via an intermediate protective connector i to a connector l holding one end of the door-side conductive cable in a hole in a door panel j,
The other end of the door-side conductive cable is connected to a 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 O. 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 operation unit 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. When the opening and 2 levers p are locked, if you tilt it backwards from the neutral position, the bell crank lever m will rotate clockwise and unlock.On the other hand, by manually operating the indoor lock knob n up and down, the bell crank lever m will be unlocked. door lock via p
The door-side conductive cable is arranged so that the locking and unlocking operations by the indoor lock knob n and the locking and unlocking operations by the remote control handle d are performed independently of each other. The rfA section of is connected to the bell crank lever m via a play connection mechanism (not shown).

The present invention provides a remote control device for an automobile door lock, including a remote control knob that rotates via a support shaft, and a power transmission that is arranged in the direction of rotation of the remote control handle and is connected to the handle. The mechanism of the connection part with the cable 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 end of the wire exposed from the outer tube at least by the amount of axial movement required for locking and unlocking operations rotates via a support shaft at the middle part of the operating handle. A configuration in which the

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 with attention to the above-mentioned points, and a connecting rod is provided at the end of the wire to be exposed to the outside from the inside of the outer tube, and the connecting rod is pivoted relative to the remote control handle. By connecting to the supported rotary connecting body, when operating the remote control handle, the outer tube portion follows the opening while reducing the amount of displacement of the connecting rod, thereby making it possible to operate the remote control handle. reduce the load,
This is to ensure smooth operation.

An embodiment of the present invention will be described below with reference to the drawings.
In FIGS. 2 and 3, the remote control handle d has a channel-shaped frame 2 fixed to a base l fixed near the driver's seat of the vehicle body via bolts 3 and nuts 4. Between the supporting plates 2a and 2b that are erected to face each other, the pin 5 passes through the holes of the supporting plates 2a and 2b to bring the head 5a on one side into contact with the outer surface of the supporting plate 2a, and the pin 5 on the other side 5.
b protrudes from the support plate 2b and is secured by an E-clip 6. The pin 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.

A coiled spring 9 1 is mounted on the outer periphery of the collar 8 placed over the pin 5 to hold the handle d in a neutral position. That is, the bent end 9a of the coiled spring 9 engages with the front surface 10a of the folding plate 10 of the forked handle d, and the end surface J of the movement permitting hole 2a+ protruding from the support plate 2a.
The other (7) bent end 9b engages with the rear surface tta of the other side plate 11 of the bifurcated handle d, and the support plate 2
It engages with the end face of a movement permitting hole 2kl drilled in b, and when the handle d is rotated forward (leftward in Figure 2) during locking operation, the handle d restrains the bent end 9a of the spring 9. At the same time, the handle d is rotated through the movement permitting hole 2a+ while resisting the elasticity of the spring, and when the handle d is released, the restoring force of the spring 9 causes the handle d to return to the neutral position shown in FIG. 2 via the bent end 9a. Return automatically. The operation when the handle d is rotated rearward (rightward in FIG. 2) during the unlocking operation is also the same as described above.

The conduction cable e is an outer tube 12 made of a flexible synthetic resin material such as polyethylene.
A straight connecting pipe 14 made of a hard synthetic resin material is connected to the outer tube 12 at the end of the conductive cable e by appropriate crimping means.
