Control mechanism elements such as the inside handle for opening the door (G ), etc., to connect them as required.

In addition, in order to control the locking and unlocking of the door lock in which the control mechanism elements (4) to (Fl) are installed from another location, for example from the driver's seat, an electrically operated actuator is used. It is connected to the lock/unlock lever on the door lock body and is electrically operated remotely.

(Disadvantages of the Prior Art) Each control mechanism element in such a conventional door lock control device is arranged at a convenient mounting position for operation, and is connected to each other by a connecting member such as a rod (G). A high degree of precision is required in the length and bending shape of the rod (Gl), and it is also necessary to provide means for finely adjusting the working length at least at one end of each rod (G).

Furthermore, there are a large number of rod connecting parts as described above, which makes it difficult to assemble to the door (4), and as a result, the layout of each control mechanism element must be done with consideration to assemblability, etc. As a result, there is a drawback that a suitable position convenient for operation cannot be expected.

In addition, since a plurality of connecting rods (G) operate in conjunction with each other at the same time, noise is generated inside the door (4), and in remote operation, the actuator (6)
It has the disadvantage of generating especially loud noise due to its sudden operation.

In addition, this actuator requires a configuration that generates driving force in both the locked and unlocked positions and also allows manual operation, so it is complex and expensive due to its structure using motors, clutches, etc. The disadvantage is that it requires something.

The above is about one door (4), and in a car with many doors, the number of parts increases.
This results in an increase in assembly man-hours, an increase in manufacturing time, etc., and as a result, the price increases.

Still, in order to eliminate the above-mentioned drawbacks, the present inventor has already invented a door lock control device that performs all door lock operations electrically, and has filed a separate application. Although this device is extremely convenient, it has the disadvantage that in order to open and close the door, the user must learn how to operate a switch for locking/unlocking the door.

(Purpose of the Invention) The present invention basically operates the door lock using an electric switch, but uses a conventional mechanical mechanism for the operation, which eliminates the trouble of learning a new operation. To provide an automobile door lock control device that eliminates the drawbacks of the conventional technology, and also enables greater freedom in design, improved aesthetic appearance, simplified configuration, and improved ML attachability, etc. The purpose is to

FIG. 6 shows an example of an electric control circuit.

This control circuit enables or disables the operation of the lock release operation switch according to the operating state of the lock detection switch (S-L, ), and when enabled, operates the lock release operation switch. It has a function that allows the actuator to be driven by disabling the actuator, and disables the actuator from being driven when the actuator is disabled.

Hereinafter, a specific example will be described based on FIG. 6.

+261 is a selection control means, that is, a relay contact, and is linked with the locking switch (S-L,).

When the lock/unlock lever (151) is in the unlocked position and the lock sensing switch (S-L+) is in the ON state, the selection control means t26) switches the switch (S-D, ),
The operation signal of (S-D2) is passed or enabled, and its output is used to set the set/reset type flip-flop circuit (two of them) in the subsequent stage.

The output (Ql) of the flip-flop circuit (2η) in this set state operates the actuator (4) via the actuator drive circuit (to) to unlock the door lock body (3).

When the lock is released and the door is opened with the striker (5) detached from the latch (6) even slightly, the door open detection switch (S) detects the open state at that time.
w ) closes and resets the clip-flop circuit Qη.

However, even though the drive device is operating to actuate the actuator (4), for some reason,
For example, if the door open detection switch (Sw) does not close because the door is stuck with a foreign object and does not open, the actuator (4) may be damaged.
For 4), a certain limit is set on the operating time.

This timed operation is obtained by a mono-stepple multi/Z-ibrator circuit configuration in which the output of the flip-flop circuit η is fed back to the reset input via a delay circuit (29).

When the lock/z-u5r is still in the locked position and the lock detection switch (s-L, ) is in the OFF state, the operation signal of the switch (S-DI) (5-D2) is , the actuator (4) cannot be activated and the door cannot be opened.

The flip-flop circuit diagram includes other control elements that are additionally added as necessary, such as child-proof locking and unlocking operation switches (S-C, ) (S-C2) locking and unlocking memory. It is a means.

The memory contents of this clip-flop circuit (7) are selectively enabled or disabled only for the lock release operation switch (S-D, ) inside the vehicle by another selection control means 01) similar to the above. to control.

In addition, or games illustrated with wired or)

The electric current to the above-mentioned control circuit is supplied directly from the exhaust system of the automobile, and the electric current is not cut off by the main start switch in the driver's seat.

However, it is better to supply power for the lock/unlock display described below through the main switch to prevent unnecessary power consumption.

The memory state of a flip-flop circuit diagram is its output (Q
With +, display means such as a light emitting diode can be turned on to display an image.

The display location, such as the light emitting diode for indicating lock/unlock, may be on the panel of the driver's seat, inside the switch, or both.

Light-emitting diodes, etc., can be used to increase safety by flashing for a certain period of time to draw attention to the locked or unlocked state of the door, such as after the main switch is turned on or after the door is locked or unlocked. be.

In the above-described embodiment configured as described above, the door opening operation section ( Even if you operate 11(2), the door will not open.

In addition, as shown by the imaginary line, by pulling up the lock/unlock knob (Iη or operating the key mechanism U■), the door opening operation parts (1) and (2) can be operated. The door will be opened.

(Second Embodiment) What is shown in FIGS. 7 and 8 is a second embodiment in which the door lock body (3) of the first embodiment described above is provided with an emergency manual unlocking means, Identical parts will be described with the same reference numerals.

The door lock body (3) is provided with horizontal protrusions (supports) + (361) that are vertically parallel to each other on the side frame Iida facing the inner panel on the inside of the door. (To 361L3fil, the upper and lower pivot stages of the handle 07 that can be rotated around a vertical axis) (layers are pivoted with a shaft (3 sickles).

A lever piece (431) extends from the lower pivot piece C38), and the tip of this lever piece 149 has an arc-shaped long hole (11bl) cut on the handle 07) side of the open lever circle.
The other end of a connecting rod (44) is connected to the connecting rod (44).

Therefore, when the handle 07) is rotated in the direction of the arrow in Fig. 8, the open lever Uυ is rotated via the connecting rod (44), the door lock body (3) is unlocked, and the door is opened. .

Note that since the handle a7) is not normally used, a cover (45) may be provided to cover the concave sound barrier 4υ for safety.

As explained above, in this second embodiment, in an emergency when the car's power supply is not fully operational,...
Rotating the force forces the latch to release and allows the door to be opened mechanically, which has the advantage of increasing safety.

(Effects of the invention) As described above, by replacing the door lock body and other control mechanism elements other than the locking/unlocking mechanism with electric switches,
The number of mechanical connecting rods is reduced, the structure of the door lock control device is simplified, and the occurrence of mechanical noise during operation and the possibility of noise generation due to vibration during driving can be reduced. This increases flexibility in terms of ease of assembly, aesthetic design, layout, etc., and provides many benefits that cannot be obtained with conventional mechanical door lock control devices.

Furthermore, it is possible to improve safety by improving the operability of opening and locking the door.

In addition, since the lock sensing switch must be operated using the lock/unlock knob and key mechanism, the trouble of learning new switch operations is eliminated, and the lock/unlock operation can be performed using the same operating procedure as before. There are also advantages to doing so.
