Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a power window control device for a vehicle.

(Prior Art) This type of power window control device has been known in the past (see, for example, Japanese Utility Model Application Publication No. 169074/1983). However, in conventionally known power window control devices, in which two operating sections, a driver's seat operating section and other operating sections, are provided in parallel, it is difficult to cancel the operation of the operating switch on the operating section other than the driver's seat. At this time, the relay is de-energized by opening the safety switch, thereby cutting off the power supply to the operating section, which complicates the circuit configuration including the relay.

In addition, in this conventional example, a three-commutator motor is used as the motor to drive the window glass up and down, but in the case of a three-commutator motor, the movable contacts are suspended in the air in the neutral state. Therefore, there is a risk of mechanical and electrical instability, as well as an increase in cost and size.

(Purpose of the invention) The purpose of the invention is to give priority to the windshield opening/closing control operation from the driver's seat over the windshield driving operation from the rear seat. The aim is to prevent danger to children (children, children).

(Structure of the invention) The present invention includes a two-commutator type motor that can rotate in forward and reverse directions and drives up and down at least one window glass of a seat other than the driver's seat, and a motor that is provided correspondingly to the motor. a motor operating section and a driver's seat operating section that enable the power supply circuit to be switched to three positions such that the movement of the window glass is raised, lowered, and stopped; and a motor operating section connected in parallel to the driver's seat operating section. and a mechanically operable control changeover switch that opens the closed power supply circuit by operating the driver's seat operation section and closes the power supply circuit that drives the window glass by operating the driver's seat operation section. In the power window control device for a vehicle, the driver's seat operating section and the motor operating section each include an ascending changeover switch and a descending changeover switch. and a control changeover switch each having two fixed contacts and one movable contact whose connection is selectively switched with respect to the fixed contacts, and a control switch for raising the driver's seat operating section. The two fixed contacts of the lowering changeover switch and the two fixed contacts of the control changeover switch are respectively connected to two electrodes of the power supply, and the movable contact of the raising changeover switch in the driver's seat operation section is connected to the motor. Connecting to one fixed contact of a raising changeover switch in the operation section, and further connecting a movable contact of a lowering changeover switch in the driver's seat operation part to one fixed contact of a lowering changeover switch in the motor operation part, A movable contact of the control changeover switch is connected to the other fixed contact of the up and down changeover switches in the motor operation section, and a movable contact of the up and down changeover switches in the motor operation section is connected to the motor. It is characterized by what it did.

(Example) Hereinafter, a power window control device for a vehicle according to the present invention will be described based on an example shown in the accompanying drawings.

Among these motors, the motor 1a for driving the driver's seat window glass is to be driven and controlled by a driver's seat operating section 6a that can be operated from the driver's seat. , an upward changeover switch 8a and a downward changeover switch 8b.

It is connected to the positive electrode side and the ground electrode side of the power source 14, respectively. Therefore, the motor power supply circuit 2a is constituted by the power supply 14, the upward changeover switch 8a, the motor 1a, and the downward changeover switch 8b. The motor power supply circuit 2a is connected to the ascending power supply circuit 4a by switching the ascending changeover switch 8a or the descending changeover switch 8b to the power supply 14 side.
Alternatively, it becomes the descending power supply circuit 5a.

Further, among the motors, a motor 1 for driving the window glass for the passenger seat and the rear seat.
b, 1c and 1d motor power supply circuits 2b, 2c
Since motors 1d and 2d have the same configuration, the motor 1d on one side of the rear seat will be described below.

The motor 1d is driven and controlled by a driver's seat operating section 6d that can be operated from the driver's seat and a motor operating section 3d that can be operated from the rear seat.

The driver's seat operating section 6d has a lift changeover switch 8a and a fall changeover switch 8b, and the motor operation part 3d has a lift changeover switch 9a and a fall changeover switch 9b. The lift changeover switch 8a is composed of two fixed contacts 12a ₁ and 12a ₂ and one movable contact 10a whose connection is selectively switched to the fixed contacts 12a ₁ and 12a ₂ . Lowering selector switch 8b

The movable contact 11b is made up of two movable contacts 11b.

Therefore, the motor 1d is connected to the movable contacts 11 of the ascending and descending changeover switches 9a and 9b.
a, 11b.

Fixed contacts 13a ₁ and 13a ₂ of the lift changeover switch 9a in the motor operation section 3d are connected to a movable contact 15 of a control changeover switch 7, which will be described later, and a movable contact 10a of a rise changeover switch 8a in the driver's seat operation section 6d, respectively. has been done.

The fixed contacts 12a ₁ and 12a ₂ of the raising changeover switch 8a in the driver's seat operating section 6d are connected to the positive electrode side and the ground electrode side of the power source 14, respectively, as in the case of the driver's seat operating section 6a.

On the other hand, the fixed contacts 13b ₁ and 13b ₂ of the lowering changeover switch 9b in the motor operation section 3d are connected to the movable contact 15 of the control changeover switch 7 and the movable contact 10b of the lowering changeover switch 8b in the driver's seat operation section 6d, respectively. ing.

Fixed contacts 12b ₁ and 12b ₂ of the lowering changeover switch 8b in the driver's seat operating section 6d are connected to the positive electrode side and the ground electrode side of the power source 14, respectively, as in the case of the driver's seat operating section 6a.

The control changeover switch 7 is mechanically operable, and similarly to the up and down changeover switches, can selectively disconnect or disconnect the two fixed contacts 16a, 16b and the fixed contacts 16a, 16b. The fixed contacts 16a and 16b are connected to the positive electrode side and the ground electrode side of the power source 14, respectively. In other words, the control changeover switch 7
They are connected in parallel to each other. code 1
7 is a fuse, and 18 is an ignition switch.

Therefore, the power supply 14, the ascending changeover switch 8
a, ascending selector switch 9a, motor 1d, descending selector switch 9b, and descending selector switch 8
The motor power supply circuit 2d is configured by the power source 14, the control changeover switch 7, the lowering changeover switch 9b, the motor 1d, the raising changeover switch 9a, and the raising changeover switch 8a. .

The motor power supply circuit 2d is connected to the lift selector switch 8a of the driver's seat operating section 6d or the motor operating section 3.
When the ascending changeover switch 9a of d is switched to the power source 14 side, the ascending power supply circuit 4d becomes the ascending power supply circuit 4d, and the descending changeover switch 8b of the driver's seat operation section 6d or the descending changeover switch 9b of the motor operation section 3d is switched to the power supply 14 side.
When switched to the side, it becomes a downward power feeding circuit 5d.

Further, the control changeover switch 7 is provided on the driver's seat side, and normally maintains the switching position of the power source 14 to the positive electrode side, but when it is switched to the ground electrode side, the motor operating portion 3d is raised. By switching the electrode 14 of the changeover switch 9a to the positive electrode side (in other words, the fixed contact 13a ₁ ), the ascending power supply circuit 4d to be closed is opened, and the descending power supply circuit 4d of the driver's seat operating section 6d is switched to the positive electrode side (in other words, the fixed contact 13a 1 ). Changeover switch 8b
on the positive power supply side of the power supply 14 (in other words, the fixed contact 1
_2b1 ) by switching to the lower feeder circuit 5
It acts so that d can be closed.

Next, the operation of the illustrated vehicle power window control device will be explained.

Ascending and descending selector switches 8a, 8b in driver's seat operating section 6d or motor operating section 3
Ascending and descending selector switch 9 at d
When operating switches a and 9b individually, the motor 1d is operated in the correct direction so that the window glass can operate according to the actions of the respective changeover switches 8a, 8b and 9a, 9b (i.e., raise, lower, and stop). Alternatively, it is rotated in the opposite direction.

It is now assumed that the lift selector switch 9a in the motor operating section 3d of the rear seat has been switched to the positive electrode side of the power source 14 (in other words, the fixed contact 13a ₁ ) as shown by the dotted line. At this time, the ascending power supply circuit 4d is closed by the power supply 14, the control changeover switch 7, the ascending switching switch 9a, the motor 1d, the descending switching switch 9b, and the descending switching switch 8b. In this state, the control changeover switch 7
on the ground electrode side (in other words, fixed contact 16b)
When switched to (shown by dotted line), the rising power supply circuit 4d is opened. After that, the driver's seat operation section 6d
When the lowering changeover switch 8b is switched to the positive electrode side of the power supply 14 (in other words, the fixed contact 12b ₁ ),
Lowering changeover switch 8b, raising changeover switch 9
b, the motor 1d, the ascending changeover switch 9a, and the control changeover switch 7 close the downward power feeding circuit 5d.

Therefore, the passenger in the rear seat can operate the motor operation section 3d.
Even if the driver attempts to raise the window glass by operating the driver's seat operation unit 6d, priority is given to the driver's lowering operation of the driver's seat operation unit 6d, and the rear seat window glass is forced to lower. In other words, dangers such as those in which a part of the passenger's body is caught in the windshield of the rear seat can be promptly eliminated by the driver's command.

In the case of this embodiment, the lowering changeover switch 9b in the motor operation section 3d of the rear seat is connected to the power source 1.
Even when the control changeover switch 7 is switched to the positive electrode side (in other words, the fixed contact 13b ₁ ) of the control changeover switch 7, the driver operation section 6d is switched to the ground electrode side (in other words, the fixed contact 16b). When the ascending changeover switch 8a is switched to the positive electrode side of the power source 14 (in other words, the fixed contact 12a ₁ ), the ascending power supply circuit 4d is closed, and the rear seat window glass is forcibly closed according to the driver's command. be forced to rise.

(Effects of the invention) According to the invention, by operating the control changeover switch (connected in series to the motor operating section) provided on the driver's seat side, the The closed power supply circuit is opened by operating the motor operating section, and the power supply circuit that drives the window glass is closed by operating the driver's seat operating section. By switching the electrode applied to one of the fixed contacts, the direction of the current applied to the power supply circuit is reversed. Therefore, when switching the control changeover switch, the switching operation on the driver's seat operation section is different from the operation on the motor operation section. Priority is given to reducing the risk of a part of the body of a rear seat passenger (for example, an infant or elderly person who does not know how to operate a power window) getting caught in the windshield by operating the driver's seat control panel. In addition to being able to remove the window quickly, if an infant or other child is in a seat other than the driver's seat and the window glass is accidentally lowered, the window glass can be forcibly lowered by operating the driver's seat control panel. It has the excellent effect of being able to prevent danger by raising the temperature.

In addition, since the structure is such that a two-commutator type motor can be used as the motor for driving the window glass up and down, the cost can be reduced and the size can be reduced compared to a conventional three-commutator type motor. Of course, the movable contact in the neutral state comes into contact with one fixed contact without floating in the air, making it mechanically and electrically stable, and
Another advantageous effect is that dynamic braking can be applied to the motor in a neutral state, making it possible to instantly stop the movement of the window glass.

Further, the raising/lowering changeover switch and the control changeover switch in the driver's seat operation section and the motor operation section are connected to two fixed contacts and one switch whose connection is selectively switched to the fixed contact. Since it is configured with movable contacts, there is also the effect that the switch configuration and circuit configuration are extremely simple.
