Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection mechanism between a wire and a bell crank lever in a differential operating 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 B5 between the vehicle body and the door, and a lock driving part C in the door, which is connected to a remote control handle d. The two vehicle body-side conduction cables e for transmitting motion to the left and right doors of the 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 to a connector e that holds one end of the door-side conductive cable in a hole in the door panel j via an intermediate protective connector i, and the other end of the door-side conductive cable is connected to a bell crank in the lock drive unit C. Connected to lever m.

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 opening/pocket p can be locked or unlocked via the bell crank lever m, and the locking and unlocking operations by the indoor lock knob n and the remote control are performed. The end of the door conduction cable is connected to the bell crank lever m via a play connection mechanism (not shown) so that locking and unlocking operations using the handle d can be performed independently.

The present invention improves the connection mechanism between the wire in the conduction cable and the bell crank lever in such a remote control device for an automobile door opening.

At the connection part between the wire and the bell crank lever,
It is necessary to perform the locking and unlocking operations using the remote control handle and the locking and unlocking operations using the indoor lock knob independently of each other, and for this reason, the wire and the bell crank lever are connected with a certain play interval. Ru.

By the way, in the case of twisting of the wire in this configuration, in the conventional mechanism, the twist of the wire is directly transmitted to the bell crank lever, and as a result, remote operation using the handle lacks smoothness.

The present invention has been made with attention to the above-mentioned points, and includes providing a rotary play connector on the connection rod at the tip of the wire, and connecting the connector with a bell crank lever, thereby connecting the rod and the connection. The purpose is to eliminate twisting of the wire between the locks and set a certain play interval, thereby achieving smooth remote control of the door lock.

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 1 fixed near the driver's seat of the vehicle through bolts 3 and naphts 4. Between the supporting plates 2a and 2b which are erected to face each other, the pin 5 passes through the holes of the supporting plates 2a and 2'b to bring the head 5a on one side into contact with the outer surface of the supporting plate 2a, and on the other side. The side 5b is provided as a shaped portion that 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 forked 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 is mounted on the outer periphery of the collar 8 that covers the pin 5 to hold the handle d in a neutral position. That is, the bent end 9a of the coiled three-pull 9 engages with the front surface 10a of the one side plate lO of the bifurcated handle d, and also engages with the end surface of the movement permitting hole 2a+ protruding from the support plate 2a. The other bent end 9b 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 when the locking operation is performed, the handle When the handle d is rotated forward (leftward in FIG. 2), the handle d restrains the bent end 9a of the spring 9 and twists it through the movement allowance hole 2a+ without resisting the elasticity of the spring. When the handle d is released, the restoring force of the spring 9 automatically returns the handle d to the neutral position shown in FIG. 2 via the bend alii 9a. 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.

A coil spring 22 is provided on the outer periphery of the wire 13 at the section 46 between the washer 20 and the cap 21 that abuts the annular step 14C and the inner end of the connecting rod 15. During unlocking operation, connecting rod 1
5 retreats while compressing the coil spring 22 via the washer 20, the coil spring 22 acts as a return spring for returning the wire 13 to the connecting rod 15 from the unlocking operation position to the neutral position.

In the above configuration, when the remote control handle d is rotated in the forward locking direction, the connecting rod 15 advances from the straight connecting pipe 14 and descends, so that the straight connecting pipe 14 to the outer pipe 12 are When the connecting rod 15 moves counterclockwise and returns to its original position, the connecting rod 15 rises and retreats into the straight connecting pipe 14.
5 rotates in the direction of the hour hand, so that the rod 15 or the wire 13 can be smoothly moved to the neutral position.Next, smooth movement is ensured in the unlocking operation as well. .
