Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a so-called power window regulator switch that opens and closes the windows of automobiles etc. using a motor.

[Conventional technology]

Conventional window regulator switches have a single knob that allows for manual operation, in which the window opens and closes only while the knob is pressed, and automatic operation, in which once the knob is pressed, the window is self-maintained until the window is fully opened and closed. It was being done. Furthermore, manual operation and automatic operation could be arbitrarily selected by simply operating one knob, making the switch easy to operate.

[The problem that the idea aims to solve]

However, as mentioned above, since all operations are performed with one knob, it is easy for erroneous operations to occur.Especially, when canceling automatic operation midway through, the self-retaining knob is moved in the opposite direction (opening, closing, etc.). For closing operation, the operation must be performed in the direction of opening operation), requiring a strong operating force, and in the worst case, there was a problem that the operation would shift to the opposite automatic operation.

This invention was made in view of such circumstances,
The purpose of the present invention is to provide a switch in which erroneous operation is less likely to occur by separating the knob into manual operation and automatic operation. A further object of the present invention is to provide a switch that uses a manual knob to open the normally closed contact of the switch when the automatic operation is stopped, and the operating force is constant and light.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a case, a manual knob and an autoknob that are pivotally supported with respect to the case, and a manual knob and an autoknob that are inserted into holes in the lower protrusions of the manual knob and autoknob. Each indenter is biased downward by a spring, each separate moderation portion is in contact with each indenter and has a substantially V-shaped concave surface formed on the upper surface of the case, and is guided by the case and engages with the manual knob and autoknob. A manual card and an auto card that move to the left and right in conjunction with their operations, two sets of switches whose contact groups are opened and closed by the movement of the manual card or auto card, and a switch from the left and right ends of the auto card. The solenoid is equipped with a two-way solenoid that has a core that engages with an arm that hangs downward, and that self-holds the autoknob in conjunction with the operation of the autoknob.

[Effect]

Two sets of switches are opened and closed by movement of a manual card linked to the manual knob or an auto card linked to the auto knob.

Therefore, if the autoknob is self-holding, operating the manual knob in the direction opposite to the self-holding side of the autoknob will cause a set of switches in the electrical path to be normally closed by moving the manual card. The contact is opened and automatic operation is canceled.

〔Example〕

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

1 to 5 are diagrams showing the mechanism of the switch. 1 is a case, 2 is a manual knob, 3 is an auto knob, and each knob 2 and 3 is connected to each hub 2.
It is swingably attached to the case 1 by a shaft 4 that is fitted into the shaft holes 2b and 3b of the shafts a and 3a. Furthermore, a protrusion 2 formed on the lower surface of each knob 2, 3
On one side of c, 3c, there are vertical grooves 2d, 3d.
are formed on the manual card 10 and the protrusion 10 provided on the auto card 11, which will be described later.
b, 11b. The manual knob 2 is loosely engaged with the hole 3e of the auto knob 3, and each knob 2, 3
can be oscillated independently of each other.

The indenters 5 and 6, which are biased downward by springs 7 and 8 inserted into the lower holes of the protrusions 2c and 3c of the knobs 2 and 3, each have a V-shaped concave upper surface formed in the case 1. It is in contact with the moderation parts 9a and 9b,
The knobs 2 and 3 are pressed into the moderation portions 9a and 9 by the indenters 5 and 6.
It acts to hold it at the center position of b.

10 is a manual card, 11 is an auto card, and rectangular holes 10a, into which the protrusions 2c and 3c of the manual knob 2 and autoknob 3 are inserted;
11a is formed, and each hole 10a, 11
In the longitudinal center part of a, grooves 2d of each knob 2, 3,
Protrusions 10b and 11b are provided to engage with 3d. Therefore, when each knob 2, 3 is swung, each card 10, 11 is moved by the interlocking operation caused by the engagement of each groove 2d, 3d with each protrusion 10b, 11b.
Move horizontally left and right. When the manual card 10 or the auto card 11 moves to the left or right, the contact 1 of the movable plate 13 having a leaf spring action
3a or 13b and the contact point 12 of the first fixing plate 12
a or 12b is opened, and contact 1 of contact 13a or 13b and second fixing plate 14 is opened.
A normally open contact with 4a or 14b is closed.
Therefore, two sets of transfer switches are formed which are opened and closed by the movement of the card. Contacts 13a and 13b are terminals 15 and 16, respectively.
electrically connected to.

U-shaped arms 11c hanging downward from both ends of the auto card 11 have a core 17 fitted in a recess 11d, and when the auto card 11 moves left and right, the core 17 in the bidirectional solenoid 18
Move the position left or right. The solenoid 18 has a coil 18a and a yoke 18b (FIG. 5).

FIG. 6 is a control circuit diagram of a motor operated by switching the contacts described above. B is a terminal connected to a predetermined DC power supply, and E is a ground terminal. Contact 1
4a, 14b are connected to terminal B, contact 1
2a and 12b are connected to the inverting terminal of a comparator C with a return resistor _R4 and to a terminal E via a current sensing resistor _R1 . Contacts 13a and 13b are connected to motor M via terminals 15 and 16, respectively.
A bridge circuit is formed between the terminals 15 and 16 by diodes D ₁ to D ₄ , and the positive side apex is the connection point P between the diodes D ₁ and D ₂ , and the negative side apex is the connection point P of the diodes D 1 to D 4 . Connection point N between D ₃ and D ₄
The collector and emitter of a transistor Q are connected in series with a parallel circuit of a bidirectional solenoid 18 and its reverse pressure prevention diode _D5 .
Connection point P is connected to transistor Q via resistors R ₅ and R ₆
connected to the base of. One end of resistor _R6 is connected to the non-inverting terminal of comparator C via resistor _R3 ,
Further connected to terminal E via resistor R ₂ , while
It is also grounded via a Zener diode ZD that provides a constant voltage. The output terminal of comparator C is connected to the base of transistor Q.

To explain the operation, as shown in Fig. 2, when the manual knob 2 is swung to the left around the shaft 4, the manual card 10 is moved to the right, so the normally closed contacts 12b and 13b are opened, and the normally closed contacts 12b and 13b are opened. Contacts 13b and 14b are closed. Therefore, terminal B, contacts 14b, 13b, terminal 16, motor M, terminal 1
5. Current flows through the contacts 13a and 12a, the resistor R ₁ , and the terminal E, and for example, the motor rotates in the forward direction, driving the window in the direction of closing. more diode
Current flows through _D2 , the solenoid 18, the collector of the transistor Q, the emitter, and the diode _D4 , but since the core 17 in the bidirectional resonoid 18 attached to the auto card 11 is not moving, the manual knob 2 is Not self-maintained.
Therefore, when you let go of the manual knob 2, the indenter 5
The knob 2 returns to the neutral position, and the contacts 13b and 14
b opens again, so motor M stops.

Next, when the manual knob 2 is rocked to the right, the manual card 10 closes the contacts 13a and 14a.
5, motor M, terminal 16, contacts 13b, 12b,
Current flows through resistor R ₁ and terminal E, and motor M
rotates in the opposite direction and drives the window in the direction that opens it.
At this time, current flows through the solenoid 18 via the diodes D ₁ and D ₃ , but as in the case described above, the core 17 within the solenoid 18 does not move, so the manual knob 2 is not self-held. When the hand is released, the manual knob 2 returns to the neutral position in the same manner as described above due to the action of the indenter 5 which is brought into contact with the moderation section 9a by the spring 7 and tends to be located at the center position of the moderation section 9a.

Next, when the autoknob 3 is swung to the left, the autocard 11 is moved to the right, so that the contacts 13b and 14b are closed. Therefore, the motor M is driven in the same way as when the manual knob 2 is swung to the left.
At this time, since the core 17 is moving to the right along with the auto card 11, the auto card 11 is held in a rightward moved state by the excitation force of the solenoid 18. Therefore, the autoknob 3 that engages with the autocard 11 is held in a state of being swung to the left against the action of the indenter 6, which attempts to position itself at the center position of the moderation portion 9b due to the force of the spring 8. . When the window is completely closed, the load current of the motor M increases, so the voltage drop across the resistor _R1 increases. Therefore, from the reference voltage obtained by dividing the constant voltage given by the Zener diode ZD by resistors _R3 and _R2 ,
The voltage drop across _R1 increases and the output of comparator C goes from high to low. As a result, the transistor Q is turned off, the excitation of the solenoid 18 is released, the self-holding is also released, and the autoknob 3
returns to the neutral position by the action of the indenter 6.

When autoknob 3 is swung to the right, contact 13a
and 14a are closed, and the motor M is rotated in the opposite direction and driven in the direction of opening the window. At this time, the autoknob 3 is connected to the solenoid 1 via the autocard 11.
The self-holding is carried out by the excitation force of 8, and the self-holding is released when the window is completely opened, which is the same as in the case described above.

Next, if the automatic operation is to be stopped midway through the automatic operation, the manual knob 2 is swung in the opposite direction to the direction in which the automatic knob 3 is self-held. Then, the normally closed contacts 12a and 13a on the path from the motor M to the terminal E are closed or the normally closed contacts 12b and 13b are unclosed, so the power to the solenoid 18 and the motor M is cut off. Then, the motor M stops rotating.

[Effect of idea]

As described above, according to the present invention, since the automatic knob and manual knob are separated, erroneous operation is less likely to occur. Additionally, if you want to stop auto operation midway through auto operation, you simply operate the non-self-holding manual knob in the opposite direction to the self-holding side of the auto knob to open the normally closed contact, so the operating force is constant. It is light and exactly the same as normal manual operation.
