Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic vehicle window opening/closing device.

[Prior art]

Conventionally, in the automatic opening/closing device of this applicant, Japanese Patent Application Laid-open No. 5
As disclosed in Japanese Patent No. 5-36119, there is a vehicle in which a window is automatically fully closed in response to a door lock when the ignition switch of a vehicle is opened.

[Problem that the invention seeks to solve]

However, in such a configuration, the windows are always kept fully open with the doors locked after the ignition switch is opened, so if, for example, a remaining occupant in the vehicle tries to open the window in such a state, There is also the problem that it is impossible to maintain the window in a half-open state.

On the other hand, as disclosed in Japanese Utility Model Application Publication No. 58-28598, there is a system in which an automatic opening/closing device is kept in operation within a certain period of time after the ignition switch is opened. The rest is JP-A-55-3.
A problem similar to that of Publication No. 6119 arises.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide an automatic vehicle window opening/closing device which maintains an operating state until a certain condition is established after the operation of the vehicle's ignition switch is released. That is.

[Means for solving problems]

In solving this problem, the structural features of the present invention are as follows:
a drive mechanism that closes a vehicle window in a first operating state and opens the window in a second operating state; and a drive mechanism that is operated when closing the window to generate a closing operation signal to open the window. an operating means that is operated to generate an opening operation signal when the ignition switch of the vehicle is operated, and a first operation means that is activated under operation of an ignition switch of the vehicle and is required to place the drive mechanism in its first operation state in response to the opening operation signal. generating and applying a second output signal to the drive mechanism; generating and applying a second output signal to the drive mechanism necessary to place the drive mechanism in its second operating state in response to the opening operation signal; In the automatic opening/closing device, the window is in a substantially fully closed state, and an output signal generating means that becomes inactive and prohibits generation of the first and second output signals in response to release of the ignition switch. a detection means for detecting this and generating a detection signal when the ignition switch is released; and a detection means for maintaining the output signal generation means in an activated state in response to the release of the operation of the ignition switch, and deactivating the output signal generation means in response to the detection signal. The present invention is also provided with operation and maintenance means for maintaining the state.

[Function and effect of the invention]

Therefore, by configuring the present invention in this way, even if the operation of the ignition switch is released with the window open, the operation maintaining means maintains the operation of the ignition switch when the detection signal disappears. In response to the release of the operation, the operating state of the output generating means is maintained continuously, and this operating state is released only by generation of the detection signal, so that even after the operation of the ignition switch is released, the window remains substantially fully closed. The opening/closing of the window can be automatically controlled by operating the operating means on the precondition that the opening/closing window is not closed. In such a case, when the window can be fully closed, if the window is fully closed by operating the operating means, the output signal generating means is deactivated, thereby saving unnecessary power consumption. is also helpful.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an automatic opening/closing device according to the present invention applied to a driver's door window of a vehicle, and this automatic opening/closing device includes a forward/reverse rotary electric motor M operatively connected to the window, and a A diode 10 connected to a DC power source B via the ignition switch IG of the vehicle, a power supply relay 20 connected to the diode 10 and the DC power source B, and a closing switch 30a and an opening switch disposed at appropriate locations on the inner wall of the driver's door. It includes a switch 30b, a control circuit 40 connected to a rotary electric motor M, a power supply relay 20, a closing switch 30a, and an opening switch 30b.

The power supply relay 20 has an electromagnetic coil 21 and a normally open switch 22 that is closed (or opened) by excitation (or demagnetization) of the electromagnetic coil 21, and the electromagnetic coil 21 is grounded at one end. The other end is connected to a DC power supply B via a diode 10 and an ignition switch IG. In response to the closing of the ignition switch IG, the electromagnetic coil 21 is supplied with power from the DC power supply B through the diode 10 and is excited, and is demagnetized when the ignition switch IG is opened. The switch 22 is connected between the control circuit 40 and the DC power supply B, and when closed, allows power to be supplied from the DC type tAB to the control circuit 40,
This power supply is cut off by opening.

The opening switch 30a is operated when the window is closed and generates a closing operation signal, while the opening switch 30b is operated when the window is opened and generates an opening operation signal. The control circuit 40 generates a reversal signal necessary for forward rotation of the rotary motor M in response to an opening operation signal from the closing switch 30a while being supplied with power from the DC power supply B through the switch 22 of the power supply relay 20. In response to the opening operation signal from the opening switch 30b, a reversal signal necessary for reversing the rotary electric motor M is generated. The rotary electric motor M rotates in the normal direction to close the window in response to a normal rotation signal from the control circuit 40, and rotates in the reverse direction to open the window in response to a reverse rotation signal from the control circuit 40. The generation time of the closing operation signal from the closing switch 30a coincides with the generation time of the normal rotation signal from the control circuit 40, while the generation time of the opening operation signal from the opening switch 30b coincides with the generation time of the normal rotation signal from the control circuit 40. coincides with the occurrence time of the reversal signal.

Further, the automatic opening/closing device includes a normally closed type fully closed detection switch 50 and an auxiliary power supply circuit 60.
0 is grounded at one end and connected to the auxiliary power supply circuit 6 at the other end.
It is connected to the DC power supply through a resistor 61 of zero. Therefore, the fully closed detection switch 50 opens when the window is fully closed and generates the power supply voltage from the DC power source B as a fully closed detection signal, and this fully closed detection signal is closed and disappears when the window is opened. let

The auxiliary power supply circuit 60 has a capacitor 62 that forms a differential circuit together with a resistor 63, and a flip-flop 64. The capacitor 62 is grounded at one end through the fully closed detection switch 50, and connected to the resistor at the other end. It is grounded through 63. Therefore, the capacitor 62 is connected to the resistor 63 in response to the generation of the fully closed detection signal from the fully closed detection switch 50.
A positive differential pulse is generated at the common end with The flip-flop 64 has a resistor 65a at its set terminal 64a.
The reset terminal 64b of the flip-flop 64 is connected to the ground through the capacitor 62 and the fully open detection switch 50. The flip-flop 64 receives the power supply voltage from the DC power supply B through the ignition switch IG and generates a low level signal at its output terminal 64C.
This low level signal is made high level in response to the differential pulse from the capacitor 62.

NOR gate 66 is connected at its first input terminal to output terminal 64c of flip-flop 64, and this
A second input terminal of the R gate 66 is connected between the capacitor 62 and the fully closed detection switch 50 through a resistor 66a. Therefore, the NOR gate 66 is connected to the fully closed detection switch 5.
When the fully closed detection signal from 0 disappears, a high level signal is generated in response to the low level signal from the flip flop 64, and this high level signal is used as the high level signal from the flip flop 64 and/or fully open. Detection switch 50
It goes low level in response to the generation of the fully closed detection signal from.

The transistor 67 has N at its base through a resistor 67a.
It is connected to the output terminal of OR gate 66, and the emitter of this transistor 67 is grounded. However,
Transistor 67 is biased into conduction by resistor 67a in response to the high level signal from NOR gate 66, and becomes non-conductive when the high level signal from NOR gate 66 disappears. The transistor 68 has its base connected to the collector of the transistor 67 through a resistor 68a, and the emitter of the transistor 68 is connected to the power supply relay 20.
The transistor 8 is connected between the switch 22 and the DC power supply B, while the collector of the transistor 8 is grounded through the resistor 68b and the electromagnetic coil 21 of the power supply relay 20. Thus, the transistor 68 becomes conductive in response to the conduction of the transistor 67, allowing power to be supplied from the DC power supply B to the electromagnetic coil 21 via the resistor 68b, and this power is supplied to the electromagnetic coil 21 by the transistor 67.
In response to non-conduction, the circuit becomes non-conductive and shuts off.

Note that the diode 10 is connected to a resistor 65 from the electromagnetic coil 21 side.
Prevents current from flowing into b.

In this embodiment configured as above, when the ignition switch IC is closed, the electromagnetic coil 21 of the power supply relay 20 receives power from the DC power supply B through the diode 10 and is excited, and in response, the switch 22 is closed, allowing power to be supplied from the DC power supply B to the control circuit 40, and placing the control circuit 40 in an operating state. Therefore, closing switch 3
When a closing operation signal is generated from 0a, the control circuit 40 generates a normal rotation signal, and in response to this, the rotating electric motor M rotates in the normal direction to close the window. On the other hand, the opening operation switch 30b
When an opening operation signal is generated from the control circuit 40, the control circuit 40 generates a reverse rotation signal, and in response to this, the rotary electric motor M rotates reversely to open the window.

By the way, when the window is open when the ignition switch IG is closed, the fully closed detection switch 50 eliminates the fully closed detection signal due to its closing, and the flip-flop 64 detects the fully closed state of the ignition switch IC. A low level signal is generated in response to the above-mentioned closure, and NO
The R gate 66 generates a high level signal based on the generation of the low level signal from the flip-flop 64 and the disappearance of the fully closed detection signal from the fully closed detection switch 50, and both transistors 67 and 68 become conductive via the resistor 68b. Direct power supply to the electromagnetic coil 21 from the power source B is allowed.

In this state, when the ignition switch IG is opened, the electromagnetic coil 21 of the power supply relay 20 is cut off from receiving power from the DC power supply B via the ignition switch IG, but the low level signal from the flip-flop 64 remains unchanged. The high level signal from the NOR gate 66 is maintained, and when both transistors 67 and 68 are conductive, power is supplied from the DC power supply B to the electromagnetic coil 21 via the resistor 68b after the ignition switch (G) is opened. In other words, the control circuit 40 maintains the auxiliary power supply circuit 60 when the fully closed detection switch 50 is closed.
Under this action, even after the ignition switch IO is opened, it continues to receive power from the DC power supply B via the power supply relay 2o and maintains its operating state.

Therefore, under the precondition that the window is not fully closed, even if the ignition switch IC is opened, the window can be automatically opened in the same manner as described above by operating the close switch 30a or the open switch 30b. Alternatively, the window can be opened, and if necessary, the window can be kept open to the extent that it is not fully closed. Further, if the window can be fully closed, the same window may be fully closed by operating the closing switch 30a in the same manner as described above, and in this case, the fully closed detection switch 50 generates a fully closed detection signal. In response, capacitor 62 generates a differential signal to invert the low level signal from flip-flop 64 to a high level signal. Then, both transistors 67 and 68 respond to the high level signal from the flip-flop 64.
Both become non-conductive under the control of the OR gate 66 and the resistance 68
The power supply to the electromagnetic coil 21 from the DC power supply B via the power source B is cut off. For this reason, the power supply relay 20 closes the switch 22 by demagnetizing the electromagnetic coil 21, cutting off the control circuit 40 from the DC power supply B and placing the control circuit 40 in an inactive state.

This helps save unnecessary power consumption.

Next, a modification of the above embodiment will be explained with reference to FIG. 2. In this modification, the door lock detection switch 70. The fact that a timer 80 and an OR gate 90 are additionally adopted has the following advantages in its structure.

The door lock detection switch 70 is powered by DC power supply B.
and the timer 80. The door lock detection switch 70 closes in response to the unlocking of the driver's door, generates an unlock detection signal at a high level, and transmits this unlock detection signal in response to the locking of the driver's door. to develop and disappear. The timer 80 generates a timer signal at a high level for a predetermined period of time in response to the unlock detection signal from the door lock detection switch 70. The OR gate 90 has its first input terminal connected to the collector of the transistor 68 via the resistor 68b of the auxiliary power supply circuit 60, and its second input terminal connected to the timer 80.
The output terminal of the OR gate 90 is connected between the diode 10 and the electromagnetic coil 21. Note that the other configurations are the same as those of the previous embodiment.

In this modified example configured in this manner, even if a full open detection signal is generated from the full open detection switch 50 after the ignition switch IG is opened, the lock detection signal is not detected based on the unlock detection signal from the door lock detection switch 70. If the timer 80 is generating a timer signal, the electromagnetic coil 2
1 receives the timer signal from the timer 80 through the OR gate 90 and maintains the excited state. Therefore, while the timer signal from the timer 80 is being generated, even after the window is fully closed while the ignition switch IG is open, the closing switch 3
By operating the opening switch 30a or the opening switch 30b, the window can be automatically closed or opened similarly to the embodiment described above. This means that even if the window is erroneously opened fully, the automatic closing/opening control of the window can be performed after the timer signal from the timer 80 is generated.

In carrying out the present invention, the auxiliary power supply circuit 60 or the timer 80, for example, disconnects the connection of the closing switch 30a and the opening switch 30b to the control circuit 40, thereby achieving substantially the same effect as that of the embodiment described above. You may try to achieve it.

Furthermore, in the embodiments and modifications described above, the present invention is applied to an automatic opening/closing device for a window on a driver's door of a vehicle. The present invention may be applied and implemented.
