Description

[Detailed Description of the Invention] The present invention relates to a control device for a power window regulator for an automobile. BACKGROUND OF THE INVENTION Conventionally, power window regulators have been known that use electric motors to open and close automobile window glasses. However, in the conventionally known power window regulator control device, the power window regulator is driven only while the control switch is continuously operated, and when the control switch is released, the power is turned off.
The wind regulator had stopped driving. Therefore, when raising or lowering the window glass, you must operate the control switch while watching the opening and closing movement of the window glass, confirm that the window glass has reached the desired position, and then release the control switch. It was inconvenient to operate. Furthermore, it is extremely difficult and dangerous for the driver to operate the control switch while watching the opening and closing of the window glass while the vehicle is running. The present invention was made to solve the above-mentioned inconvenience, and includes a control switch that can detect the amount of operation, and is configured so that the window glass opens and closes according to the amount of operation of the control switch. The object of the present invention is to provide a control device for an automobile power window regulator that is easy to operate. Hereinafter, the present invention will be explained in detail based on the embodiment shown in FIG. First, to explain the configuration, 1 is a battery whose negative terminal is grounded, 2 is a resistor whose one end is connected to the positive terminal of battery 1,
The other end of the resistor 2 is grounded via a variable resistor 3 and a resistor 4 for position detection. 5 is a resistor, 6 is a variable resistor for position control, and 7 is a resistor, and the series circuit consisting of resistor 5, variable resistor 6, and resistor 7 is parallel to the series circuit consisting of resistor 2, variable resistor 3, and resistor 4. It is connected to the. 8 is a transistor whose base is connected to the variable terminal 3a of the variable resistor 3, and whose emitter is connected to the variable terminal 6a of the variable resistor 6.
The collectors are respectively connected to the base of the transistor 9. 10 is a transistor whose base is connected to the variable terminal 6a of the variable resistor 6; its emitter is connected to the variable terminal 3a of the variable resistor 3; and its collector is connected to the base of the transistor 11. Further, the emitters of transistors 9 and 11 are both connected to the positive terminal of battery 1, the collector of transistor 9 is grounded via relay coil 12, and the collector of transistor 11 is grounded via relay coil 13. 120 is a relay contact that responds to the magnetic force of the relay coil 12, and the relay contact 120 includes a contact piece 120a,
It consists of a normally closed contact 120b and a normally open contact 120c. 130 is a relay contact that responds to the magnetic force of the relay coil 13, and the relay contact 130 is connected to the contact piece 1.
30a, normally closed contact 130b and normally open contact 130
It is more familiar than c. Here, the contact pieces 120a, 13
0a is connected to each terminal of the electric motor 14, normally closed contacts 120b and 130b are both grounded, and normally open contacts 120c and 130c are connected to the positive terminal of the battery 1. In the above configuration, a power window regulator (not shown) is driven by the electric motor 14, and the variable terminal 3a of the variable resistor 3 moves as the power window regulator is driven. The electric motor 14 is set to rotate in a direction in which the voltage at the variable terminal 3a decreases when the relay contact 120 is activated, and in a direction in which the voltage at the variable terminal 3a increases when the relay contact 130 operates. Next, the operation will be explained. Now, in the state shown in FIG. 1, the same voltage is applied to the variable terminal 3a of the variable resistor 3 and the variable terminal 6a of the variable resistor 6. Therefore, the two transistors 8 and 10 whose bases and emitters are connected to the variable terminals 3a and 6a are both turned off, and the base currents of the transistors 9 and 11 are cut off, so that the transistors 9 and 11 are also turned off. It's summery. Therefore,
Relay coils 12 and 13 are not energized and relay contacts 120 and 130 are also inactive, causing electric motor 14
is not working and the power window regulator has stopped. In this state, when the variable terminal 6a of the variable resistor 6 is operated to increase the voltage applied to the variable terminal 6a, in the transistor 10, [base voltage (voltage of variable terminal 6a)>emitter voltage (variable terminal 3a In the transistor 8, the base voltage (voltage at variable terminal 3a)<emitter voltage (voltage at variable terminal 6a)]. Therefore, transistor 10 is turned on, transistor 8 is turned off, transistor 11 is turned on by turning on transistor 10, only relay coil 13 is excited, relay contact 130 is operated, and contact piece 130a is normally open. It makes contact with the contact point 130c. Then, the electric motor 14 is operated and a power window regulator (not shown) is driven, and as the power window regulator is driven, the variable terminal 3a of the variable resistor 3 is set in a direction in which the voltage increases. Moving. As the variable terminal 3a moves, the voltage at the variable terminal 3a gradually increases, and when the voltage at the variable terminal 3a becomes equal to the voltage at the variable terminal 6a, the base and emitter voltages of the transistor 10 become equal, and the transistor 10
It becomes OFF. When transistor 10 turns off, the base current of transistor 11 is cut off and transistor 1
1 is turned off, the relay coil 13 is demagnetized, and the relay contact 130 becomes inoperable. Then, the electric motor 14 becomes inactive, the power window regulator stops, and the movement of the variable terminal 3a stops along with the power window regulator stopping. In other words, when the voltage applied to the variable terminal 6a is increased by operating the variable terminal 6a of the variable resistor 6,
The power window regulator is driven so that the voltage applied to the variable terminal 3a of the variable resistor 3 increases so that the voltage at the variable terminal 3a becomes equal to the voltage at the variable terminal 6a, and the voltage at the variable terminals 3a and 6a increases. Once they are equal, the drive of the power window regulator is stopped. Furthermore, when the variable terminal 6a of the variable resistor 6 is operated to reduce the voltage applied to the variable terminal 6a, in the transistor 10, [base voltage (voltage of variable terminal 6a) < emitter voltage (variable resistor 3a
voltage)], and in transistor 8,
[Base voltage (voltage at variable terminal 3a)>emitter voltage (voltage at variable terminal 6a)]. For this reason,
Transistor 10 is OFF, transistor 8 is ON
When transistor 8 is turned on, transistor 9 is turned on, and only relay coil 12 is energized, relay contact 120 is activated, and contact piece 12 is turned on.
0a contacts normally open contact 120c. Then, the electric motor 14 is activated and a power window regulator (not shown) is driven, and as the power window regulator is driven, the voltage at the variable terminal 3a of the variable resistor 3 is set in a direction in which the voltage decreases. Moving. As the variable terminal 3a moves, the voltage at the variable terminal 3a gradually decreases, and the voltage at the variable terminal 3a gradually decreases.
When the voltage of a becomes equal to the voltage of variable terminal 6a,
The base and emitter voltages of transistor 8 become equal and transistor 8 is turned off. When transistor 8 turns OFF, the base current of transistor 9 is cut off, transistor 9 turns OFF, relay coil 12 is demagnetized, and relay contact 1
20 becomes inactive. Then, the power window regulator stops, and along with the stop of the power window regulator, the movement of the variable terminal 3a stops. In other words, when the voltage applied to the variable terminal 6a is reduced by operating the variable terminal 6a of the variable resistor 6 in the same way as in the above-described operation, the power window regulator is adjusted so that the voltage at the variable terminal 3a becomes equal to that of the variable terminal 6a. The generator is driven, and the variable terminal 3a and the variable terminal 6
When the voltages a become equal, the drive of the power window regulator is stopped. FIG. 2 is a diagram showing another embodiment of the present invention,
A limit switch circuit 1 is shown in the embodiment shown in FIG.
5 is added, and transistors 8, 9, 10, 11 and variable resistors 3, 6 are connected to a battery via a limit switch circuit 15 . Here, the limit switch circuit 15
has an ignition switch 17 whose one end is connected to the positive terminal of the battery 1 and whose other end is grounded via the electric device 16, and further includes normally closed limit switches 18, each connected in parallel.
19, a diode 20, and an alarm 21 connected in parallel to the ignition switch 17. Also,
When the variable terminal 6a of the variable resistor 6 for control is operated to the position where the window glass is fully closed, the limit switch 18 is opened, and the variable terminal 3a of the variable resistor 3 for position detection is similarly moved to the position where the window glass is fully closed. When the window glass moves to a fully closed position as the shutter is driven, the limit switch 19 is disengaged. Therefore, in the embodiment shown in FIG. 2, the variable terminal of the variable resistor 6 for control is located at the position where the window glass is fully closed, and the variable terminal of the variable resistor 3 for position detection is located at the position where the window glass is fully closed. When the limit switches 18 and 19 are in the position shown in FIG.
No current flows through the terminals, etc., and unnecessary consumption of power is prevented. Furthermore, when the ignition switch 17 is released with the window glass open, current flows through the path of the limit switches 18, 19, the diode 20, the alarm 21, and the electrical device 16, and the alarm 21 is activated. Therefore, it is possible to prevent the driver from forgetting to close the window glass and leaving the vehicle. As is clear from the above explanation, when the control switch of the present invention is operated, the window glass opens and closes according to the amount of operation, so it is extremely easy to operate and is safe even when driving a car. The advantage is that the window glass can be opened and closed. Additionally, by adding a limit switch circuit that includes a limit switch and an alarm as shown in Figure 2, unnecessary consumption of power can be prevented, and it can also be prevented from leaving the car with the windows open. It has the advantage of being practical and easy to operate.
