Description

[Detailed description of the invention] The present invention is a power window operating device for automobiles, etc. that drives a wind regulator by rotating a motor in the forward or reverse direction to raise and lower the window glass. The present invention relates to a power window operation device in which the window glass is raised and lowered during automatic operation, and in automatic operation, the window glass is raised and lowered until it is fully opened or fully closed.

Conventionally, in such an operating device, the operating position of one switch (knob) is set to two levels on each side, and when one knob is pushed to the left (or right) to the first operating position, manual operation is activated. Then, if the knob is pushed to the left (or right) after the first stage to the second stage operation position, automatic operation will occur. However, since such an operating device has one knob with two operating positions, not only does it have a poor feeling when operating the knob, but when you want to stop automatic operation midway through, you have to turn the knob to the right (or The problem was that when pressing the button in the left direction, if the force was too strong, it would go into automatic operation in the opposite direction.

The present invention provides a power window operating device which eliminates such drawbacks, provides a good feeling during operation, and can prevent erroneous operations such as switching to automatic operation in the opposite direction when stopping automatic operation in the middle. With the goal.

An embodiment of the present invention will be described below with reference to the drawings.

Terminals C and D are connected to a terminal J of a control circuit 4 and a terminal I via a solenoid 3-1 that drives an armature 14, which will be described later. Terminal J is connected to a capacitor 4-7, one end of which is grounded, and a resistor 4-6, one end of which is connected to the base of a transistor 4-5, via a resistor 4-3 and a reed switch 4-4. There is. Terminal I is the transistor 4-8
It is grounded via the diode 4-2 and connected to the terminal J via the diode 4-2. Diode 4-
The cathode of transistor 2 is connected via a resistor 4-9 to the base of a transistor 4-8 and the collector of a transistor 4-5 whose emitter is grounded.

FIG. 2 shows a specific example of the structure of the switch 3, which has a first swinging operation piece 6 and a second swinging operation piece 7. As shown in FIG. The former has pressing pieces 6-1 and 6-2 that press the contacts 5-1 and 5-3, respectively, when pressed to the right or left, and the latter has pressing pieces 6-1 and 6-2 that press the contacts 5-1 and 5-3, respectively, when pressed to the right or left. Pressure pieces 7-1 to 7- for pressurizing the contacts 5-1 to 5-4, respectively
It has 4. First and second swing operation pieces 6, 7
2b (A-A sectional view in FIG. 2a) and c (BB-B in FIG. 2a) centering on the support shaft 12.
In the normal position where no pressure is applied, the former is T-shaped sliding piece 1.
The latter is held in a neutral state (horizontal state) by springs 11 through 0 and by springs 9 and 9' through flanged sliding pieces 8 and 8', respectively. Armature 14 driven by solenoid 3-1
is fixed to the support shaft 12 together with the second swing operation piece 7, and when the solenoid 3-1 is energized, the second swing operation piece 7 is held in a rotated (pressed) state to the left or right. do. This holding state of the second swing operation piece 7 is such that when the first swing operation piece 6 is rotated in the opposite direction, the ends 7-5 and 7-6 of the second swing operation piece 7 are pressed in the opposite direction. is released against the electromagnetic force of the solenoid 3-1.

Next, the operation of the above circuit will be explained with reference to FIG. 3, which shows the switching states of the contacts 5-1 to 5-4 of the switch 3. In the normal position, in which neither the first nor second swing operation pieces 6, 7 of the switch 3 are pressed, the contacts 5-1 to 5-4 are located horizontally (Fig. 3a), and the motor 2 Since no current flows, the window glass remains stopped.

Next, when the first swing operation piece 6 is rotated to the right about the support shaft 12 in FIG. 2b, the contact 5-1
is pressed down by the pressure piece 6-1 and comes into contact with the terminal A (FIG. 3b). Then power supply 1, terminal E, contact 5-3, terminal H, motor 2, terminal G, contact 5-
1, terminal A, and current coil 4-1, and the motor 2 stops rotating only while the first swing operation piece 6 is pressed, raising the window glass. This is a manual lift operation.

When the second swing operation piece 7 is rotated to the right, the contacts 5-1 and 5-2 are pushed down by the pressure pieces 7-1 and 7-2 and come into contact with the terminals A and D, respectively. (Figure 3c). Therefore, current flows through the motor 2 through the same path as when operating the lifting manual, causing the motor 2 to stop rotating. On the other hand, power supply 1, terminal E, contact 5
-3, a positive voltage is applied to the base of the transistor 4-8 through the terminal H, the contact 5-2, the terminal D, the terminal J, and the resistor 4-9, so the transistor 4-8 is turned on, and the terminal D, A current flows through the solenoid 3-1 and the transistor 4-8, and the armature 14 is attracted by the solenoid 3-1. Therefore, the support shaft 12 fixed to the armature 14 and the second swinging operation piece 7 are held in the rotational position, and even if no force is applied to the second swinging operation piece 7, the motor 2 continues to rotate in the normal direction. The windshield continues to rise. When the window glass rises and becomes fully closed, the motor 2 is overloaded and a large current flows through the current coil 4-1. As a result, reed switch 4-4 is turned on, and capacitor 4-7
is charged, and when the charge reaches a predetermined value, the transistor 4-5 turns on (the capacitor 4-7
The reed relay 4-4 is turned on by the rush current when the motor 2 starts, and the transistor 4-4 is turned on.
5), the base of the transistor 4-8 is grounded and turned off. Then, the current to the solenoid 3-1 is cut off, and the second swing operation piece 7 returns to the normal position due to the force of the spring 9, and the contacts 5-1 and 5-2 also separate from the terminals A and D. Therefore, the motor 2 stops immediately after the window glass is fully closed. This is automatic ascending operation.

When the first swing operation piece 6 is rotated to the left, the contact 5-3 is pushed down by the pressure piece 6-2 and comes into contact with the terminal F (FIG. 3d). Therefore, power supply 1, terminal B, contact 5-1, contact G, motor 2, terminal H,
Contact 5-3, terminal F, terminal K, current coil 4-1
A current flows and the motor 2 rotates in the reverse direction. Therefore, while the first swing operation piece 6 is being rotated to the left, the window glass is lowered. This is the downward manual operation.

When the second swing operation piece 7 is pushed to the left, the contact 5-
3 and 5-4 are pressed down by pressure pieces 7-3 and 7-4, and come into contact with terminals F and C, respectively (FIG. 3e). Therefore, the motor 2 rotates in the reverse direction through the same path as the lowering manual operation, and the window glass is lowered. On the other hand, power supply 1, terminal B, contact 5
-1, a positive voltage is applied to the terminal J via the contact 5-4 and the terminal C. The rest of the operation is the same as in the case of the automatic upward operation, and when the window glass is fully opened, the motor 2 is stopped. This is automatic descending operation.

To stop automatic operation during upward (or downward) automatic operation, rotate the first swing operation piece 6 to the left (to the right if automatic downward operation is in progress).
The end 7-5 of the second swinging operation piece 7 (or the end 7-6 when automatic lowering operation is in progress) is forced by the first swinging operation piece 6 against the holding force of the solenoid 3-1. The contact point 5-1, 5-2 (or 5-3, 5
-4) returns to the normal position. Therefore, the holding of the second swing operation piece 7 is released, and the rotation of the motor 2 is stopped. In this case, even if the force applied to the first swing operation piece 6 is too strong and the first swing operation piece 6 is operated in the opposite direction, this is a manual operation, so the first swing operation piece 6 The window glass will stop at the position where 6 is released.

As described above, in this invention, different switches (knobs) are pressed for manual operation and automatic operation, so not only can the feeling during operation be good, but also the automatic operation Since the manual switch is used to cancel the operation in the middle of the operation, it is possible to prevent erroneous operation that may occur if the automatic operation is started in the opposite direction.
