Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device equipped with an operating member capable of displacement operation.

Recently, in automobiles, a knob as an operating member is provided in an easily operated part such as the instrument panel or dash board, and by pressing the knob, a switch is turned on and an electrical signal is generated. It has been proposed to use an electrical signal to release a trunk lock mechanism that locks the trunk lid so that it cannot be opened. However, with the above configuration, there is a problem to be solved in that if the knob is pressed by mistake even while the car is running, the trunk lock mechanism will be released.

The present invention has been made in view of the above circumstances, and its purpose is to provide an operating device that can lock an operating member so that it cannot be operated when the operating member should not be displaced.

Now, the electrical configuration will be described according to FIG. 30 is the positive power terminal of a battery which is a DC power source, and this is branched into two, one branch end is grounded through the operation switch 12 and the excitation coil 31 of the release mechanism in series, and the other branch end is It is grounded via touch switch 21 and resistor 32 in series. In this case, when the excitation coil 31 of the release mechanism is energized, it releases a trunk lock mechanism (none of which is shown) that locks the trunk lid of a vehicle, such as an automobile, so that it cannot be opened. 33 is a running detection device which is a restraint control device that detects the running of a car, and this is a high-level prohibition signal Sa while the car is running.
is output from the output terminal. The output terminal of this travel detection device 33 is connected to the first input terminal of an AND circuit 34 which is a drive circuit, and the second input terminal of the AND circuit 34 is a detection terminal which is a common connection point between the touch switch 21 and the resistor 32. end 35 and the AND circuit 34
The output terminal of is grounded via the excitation coil 17 of the electromagnetic device 15.

Next, the operation of this embodiment will be explained.

When the vehicle is stopped, when the driver presses the push button part 7 of the knob 6 with his/her finger, the knob 6 is displaced downward against the spring force of the compression coil spring 11. Now, push button part 7
presses and displaces the movable contact piece 14 of the operating switch 12, and the contact part 14a of the fixed contact piece 13 is moved to the contact part 1 of the fixed contact piece 13.
3a, and then turn on the operation switch 12. As a result, the operation switch 12 causes a current, which is an electrical signal, to flow through the excitation coil 31 of the release mechanism, and the release mechanism operates to release the trunk lid lock by the trunk lock mechanism.

On the other hand, when the car is running, the running detection device 33 detects this and outputs a high-level prohibition signal Sa, and this prohibition signal Sa is used as an external input signal to the first is applied to the input terminal of In such a state, when the driver accidentally presses the push button 7 of the knob 6, this press causes the movable plate 24 of the touch switch 21 to displace downward, and the movable electrode layer on the lower surface of the touch switch 21 moves to the fixed electrode 22. The touch switch 21 is turned on. As a result, this touch switch 21
A current flows through the resistor 32 through the resistor 32, and the potential at the detection terminal 35 becomes high level, which is applied to the second input terminal of the AND circuit 34 as a high level detection signal Sb. Therefore, the output signal of the AND circuit 34 becomes high level, and the excitation coil 17 of the electromagnetic device 15 becomes energized, so that the plunger 19
moves to the right from its original position against the spring force of the compression coil spring 20, and the locking protrusion 18 at its tip fits into the locking recess 10 of the knob 6. Therefore, even if the driver continues to press the push button part 7 of the knob 6, the upper wall of the locking recess 10 is locked with the locking protrusion 18, and the downward displacement of the knob 6 is restrained. The operation switch 12 is never turned on.
After that, when the driver releases his finger from the push button part 7 of the knob 6, the touch switch 21 is turned off and the detection signal Sb
disappears, the output signal of the AND circuit 34 becomes low level, and the excitation coil 17 is cut off.

According to this embodiment, when the push button part 7 of the knob 6 is pressed by mistake while the car is running, the excitation coil 17 of the electromagnetic device 15 is immediately energized and the locking protrusion 18 presses the knob 6. Since the vehicle is automatically locked so that it cannot be operated, the operation switch 12 is never turned on, and therefore there is no problem of the trunk lid being unlocked and opened while driving, making it extremely safe. ,
Moreover, the driver immediately feels that the knob 6 is restricted and cannot be moved downward.
You can quickly learn that you should not press the button.

By the way, the excitation coil 1 of the electromagnetic device 15 is
7 may be directly energized, but in this case, the excitation coil 17 is always energized while the car is running and continues to restrict the pressing operation of the knob 6, leading to the problem of increased power consumption. Yes, also
Since the electromagnetic device 15 continues to generate electromagnetic noise while the vehicle is running, this is not preferable in terms of noise prevention. On the other hand, in this embodiment, when the push button part 7 of the knob 6 is pressed while the automobile is running (while the prohibition signal Sa is being output) (the detection signal Sb is not being output). electromagnetic devices (15)
Since the excitation coil 17 is energized, the excitation coil 17 is energized only for a short period of time when the push button 7 of the knob 6 is pressed even when the vehicle is running, so that power can be saved. As well as being able to
The generation time of electromagnetic noise is also short and it is effective in preventing noise.

In the above embodiment, the knob 6 is provided with a touch switch 21 that detects the touch of a finger on the push button 7 and turns on the touch switch 21. Attach the light emitting element 36 and the light receiving element 37 to the case 1, and turn the knob 6.
The photoelectric switch 3 is configured such that when a finger approaches the push button section 7 of the driver, detection light from the light emitting element 36 is reflected by the driver's finger and received by the light receiving element 37, thereby turning on the switching element.
8 may be used as a detector.

Further, in the above embodiment, the release mechanism for releasing the trunk lock mechanism is activated by the electrical signal generated by turning on the operating switch 12, but instead, the bonnet lock mechanism that locks the bonnet so that it cannot be opened is activated. A release mechanism may be operated, or a release mechanism may be operated that releases a lock button locking mechanism that locks a lock button of a shift lever in an automatic transmission inoperable.

Furthermore, in the above embodiment, the operation switch 12
A release mechanism that releases the ignition switch lock mechanism that locks the ignition switch so that it cannot be operated is operated by an electrical signal caused by turning on the ignition switch, and furthermore, when refueling is being detected, a high-level prohibition signal is issued. A refueling detection device, which is a restraint control device, may be provided, and the high-level prohibition signal may be applied to the first input terminal of the AND circuit 34. In this case, the ignition switch is activated during refueling. can be prevented from being manipulated.

Furthermore, in the embodiment described above, the operation switch 12 is turned on by the downward displacement of the knob 6 by the pressing operation, and an electrical signal is generated.
Instead, the downward displacement of the knob 6 is transmitted to the trunk lock mechanism, bonnet lock mechanism, lock button lock mechanism, or ignition switch lock mechanism via a transmission member such as a flexible wire, and the lock is mechanically released. It's okay.

In addition, the present invention is limited only to the embodiments described above and shown in the drawings, and can be applied not only to automobiles but also to general operating devices for various devices.
Of course, modifications may be made as appropriate without departing from the spirit of the invention.

As explained above, the present invention includes a restraining mechanism for restraining an operating member so that it cannot be operated, a detector that detects the proximity or contact of an object to the operating member and generates a detection signal, and an external In the case where an input signal exists and the detector generates a detection signal, a drive circuit is provided that causes the restraining mechanism to restrain the operating member, so that when the operating member should not be displaced. The operating member is automatically restrained so that it cannot be operated, making it extremely safe.Moreover, the restraint mechanism operates only when an external input signal is present and a detection signal is output, so it is practical and can save power. It is possible to provide an operating device that has a desired effect.
