Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle door lock device, and more particularly to a remote control device for a door lock 5 mechanism equipped with a locking/unlocking mechanism and a child safety lock.

Conventionally, door-sick mechanisms for automobiles include a locking/unlocking mechanism that allows the door to be opened according to the operation of the inside handle and outside handle, regardless of whether the locking/unlocking mechanism is locked or unlocked. Various door lock mechanisms have been proposed that include a child safety lock that makes it impossible to open the door by operating an inside handle.

The child safety lock is designed to prevent children inside the vehicle from opening the door mischievously while the vehicle is running.In addition to children, when the child safety lock is locked, passengers inside the vehicle cannot open the door. The door is constructed in such a way that it is impossible to open it.

However, these locking/unlocking mechanisms and child safety locks must be locked/unlocked using a locking knob and child lever located on the door body.
Particularly in the case of a rear door, it is extremely troublesome for the driver to operate the rear door.

In order to eliminate these complications, there is a known method for locking and unlocking the locking/unlocking mechanism and child safety lock by remote control from the driver's seat, such as the one shown in Figure 1. .

This conventional remote control device 8a has a control lever 1 disposed next to the driver's seat, one end of which is connected to the control lever 1, and the other end of which controls the operation of a locking knob 39 by a door lock mechanism D.
The wire 2 is connected to a bell crank 40 that transmits to the locking/unlocking mechanism section of L. Here, D is a rear door of the vehicle, 38 is a transmission rod for transmitting the rotation of the bell crank 40 to the lock/unlock mechanism, and 3 is a child lever of the child safety lock OL in the door lock mechanism DL.

The control lever 1 of such a conventional remote control device 8a is always kept in a neutral position, and by tilting it backward, the locking/unlocking mechanism is locked, and by releasing the hand, the locking/unlocking mechanism is activated. Although it is held in the locked state, the operating lever 1 returns to the neutral position again, and by tilting it forward in the same way, the locking/unlocking mechanism DOt- can be unlocked, but even though the operating lever 1 is in the unlocked state, it returns to the neutral position. It's starting to go back.

With this configuration, the locking/unlocking mechanism can be operated remotely from the driver's seat.

Also, a device that remotely controls a child safety lock with a configuration similar to these is also disclosed in Japanese Patent Application Laid-Open No. 1986-
85121 and others have been proposed.

However, with these remote control devices, if you try to remotely control both the locking/unlocking mechanism and the child safety lock, you will have to install power for each control system separately, which can result in high costs. , two operating levers are required to be installed next to the driver's seat, which increases the installation space and narrows the interior space.In addition, in the locking/unlocking mechanism, the operating lever always remains in neutral. Therefore, there is no one-to-one correspondence between the locked and unlocked states, so the driver can only check the locked and unlocked states without looking at the state of the locking knob provided on the door body. However, it is extremely dangerous to try to find out whether the locking mechanism is locked or unlocked while driving, so it is actually impossible to do so while the driver is driving. In addition to having to drive without knowing whether the door is locked or not, conventional child safety locks do not allow the door to be opened by operating the inside handle. The so-called double lock condition in which both the locking/unlocking mechanism and the child safety lock are locked is essentially unnecessary, and because it exists, the operation itself must be performed separately. However, there is a problem in that it becomes extremely complicated.

This invention was devised in view of the current situation, and its purpose is to reduce costs, avoid constricting the interior space, and moreover, to change the locking and unlocking states of the locking/unlocking mechanism and child safety lock. It is an object of the present invention to provide a remote control device for a vehicle door lock mechanism that can be easily checked.

In order to achieve this object, the present invention provides an operation lever that is disposed next to the driver's seat in the vehicle interior and is capable of arbitrarily selecting a idle lock-on position, a neutral position, and a lock-on position. A control unit having a locking retention mechanism and a child retention mechanism is disposed between the door locking mechanism and the door locking mechanism, and the movement of the operating lever corresponds one-to-one with the locking and unlocking states of the locking and unlocking mechanism and the child safety lock. The position of the operating lever makes it easy to
Enables confirmation of current locked and unlocked status, and

A transmission rod 30 is connected. 90 is bell crank 26 for child and bell crank 2 for locking knob.
This is a stopper that restricts the rotation of 9.

As shown in FIG. 6, the door lock mechanism DL side is rotated approximately
A locking knob lever 11 in the shape of a letter is pivoted and one end 1 thereof is supported.
1H, one end of the transmission iron 38 is connected to a bell crank 40a that transmits the operation from the control unit υ, and the other end of the transmission iron 38 is connected. Further, a child lever 3 is pivotally supported on the base plate 4 by a shaft 5 with P3 as the rotation center, and a connecting portion 3b is formed in which the lower end of the child lever 3 is extended and is connected to a transmission rod n that transmits the operation from the control unit. ing.

Since the door lock mechanism DLt'i is the same as that normally used, a detailed explanation will be omitted.

Next, the operation of the remote control device for the vehicle door lock mechanism according to the above embodiment will be explained.

When the operating lever 35 of the operating lever part M is rotated to the lock-on position, the inner wire 2a of the wire 2 is pulled and the remote control wire rod R is pulled downward in FIG. 4. Then, the locking knob bell crank 29 is rotated counterclockwise in FIG. 4 by the lower protrusion 27b of the remote control wire rod I, and the transmission rod recess is pulled leftward in FIG. Turn the lever 11 clockwise in Figure 6.
11 is held in a key state. At this time, bell crank 40a
The rotation of the locking knob 39 lowers the locking knob 39 to indicate that the locking/unlocking mechanism is in the locked state. In addition, the lever 35
In this operation, the child bell crank 26 does not rotate because its one end 26b does not engage with the upper protrusion 27a when the remote control wire rod 27 is lowered, and as a result, the child safety lock OL does not become locked. .

Next, when the lever 35 of the operating lever part M is rotated past the neutral position N to the child lock on position C and locked in the stopper slit part 36a, the inner wire 2a of the wire 2 is pushed toward the rear of the vehicle body and the remote Push up the control wire rod upward in Figure 4. Then, the fifth
As shown in the figure, the upper protrusion 27a of the wire rod I
comes into contact with one end 26b of the child bell crank 26 and engages with the locking groove 26C, so that the child bell crank 26

Take it to the left in Figure 5, tension it once, and turn the child lever 3 clockwise in Figure 6.

Child 7-7 Hold the lock OL in the locked position. In this case, the above remote control wire rod H
During the upward movement, the lower protrusion 27b does not engage with the bell crank 4 for the locking knob, so the locking lever 11 is held in the unlocked state 5 degrees, and the child safety lock OL is in the locked state. 1. When the locking knob 39 is locked, -H is transmitted via the bell crank 40 and the transmission rod 30.
The locking knob lever 11 rotates in the on direction, and the locking knob bell crank 4 rotates counterclockwise in Figure 5, but due to the biasing force of the spring 32, it moves back in the clockwise direction in Figure 5. , the locking knob 39 and the locking knob lever 11 return to the unlocked state, so locking and unlocking operations from the child safety platform 39 are also possible.
The input from the locking knob 39 is transmitted by the reaction force of the spring 39, and the operating lever 35 moves from the neutral position N to the lock-on position. In the remote control device for the door lock mechanism according to this embodiment, since the locking/unlocking mechanism and the child safety lock OL can be remotely controlled by the wire 2, which is a single connection and transmission means, it is easy to operate, and Because it is operated from one series, the number of parts is greatly reduced, making assembly work easier and reducing costs.In addition, the child safety lock OL and locking/unlocking mechanism are controlled by a lever that controls the locking and unlocking states. Since the lever M can be easily operated at the 35 position, the locking/unlocking position can be easily confirmed.

Further, as shown in FIG. 7, depending on the layout inside the door D, the control unit Vt may be placed behind the door D. In this case, the transmission rod 30a is the sixth
The locking knob lever 11 shown in the figure is directly connected. The transmission rod 23a is connected to the child lever 3 similarly to the transmission rod n in FIG.

In the above embodiment, the present invention is applied to one of the vehicle doors, but the present invention may be configured so that the left and right doors can be operated simultaneously.

As explained above, according to the present invention, the cost can be reduced, the indoor space is not narrowed, the operation is easy, and the locking/unlocking mechanism and the child 7-7 lock can be easily locked and unlocked. This has the effect of allowing one to recognize the situation.
