That is, the switches S2 to S8 correspond to the electric motors M1 to M7, and the switches S9 to S1
Reference numeral 3 corresponds to the electric motors M3 to M7.

The vehicle 11 is an automatic vehicle, and the limit switch LP is an a-contact type limit switch that forms a closed circuit when the automatic gear is switched to the parking position. The limit switch LQ is
This is an a-contact type limit switch that forms a closed circuit when the automatic gear is switched to a position other than parking, such as drive, reverse, second, and neutral.

As shown in FIG. 6, the limit switch LA is a b-contact type limit switch which is opened when the sunshade 5a on the driver's seat side of the windshield 13 partially shields the windshield 13 to avoid backlight. .

As shown in FIG. 7, the limit switch LB is a b-contact type limit switch which is opened when the sunshade 5b on the front seat 13 of the windshield 13 partially shields the windshield 13 to avoid backlight. .

The positions of the sunshades 5a and 5b at which the limit switches LA and LB are released are positions on the windshield 13 where the backlight is sufficiently prevented from entering the field of view but does not obstruct the driving field of view. In other words, this is the limit position where operation is hindered if the sunshades 5a and 5b descend further.

a, an a-contact type limit switch which is closed when the sunshade on the rear seat window side on the passenger side and the sunshade 6 on the rear glass 14 are completely closed.

In the multiple power window of the present embodiment, if the switch S14 is always closed, all awnings are completely closed when parking, and direct sunlight does not enter the vehicle from anywhere. . From this state, when the switch S1 is closed and the engine is started, and the automatic gear is switched to a position other than parking,
Electric power is supplied to all of the electric motors M1 to M7 in a direction in which the limit switch LQ is closed and all awnings are opened. At this time, one line is branched from the 12V side of the power supply, and power is supplied to each part of the motors M1 to M7. However, since a diode is interposed in each branch part in the forward direction, the switches S2 to S7 are switched. Electric motors M1 to M7 at the time of operation of S13
There is no possibility that the current spills to other parts and malfunctions.
That is, a circuit that connects the 12V side of the power supply to the motors M1 to M7 via the limit switch LQ and performs an operation of opening each sunshade constitutes an automatic release unit.

When all the awnings are opened, the limit switches L1 to L7 connected in series are closed, and power is supplied to the relay Y. Then, among the contacts of the relay Y, b
One of the contacts is connected in series with the limit switch LQ in the course of connection from the 12V side of the power supply to the electric motors M1 to M7, and when all the awnings are fully opened, the power for opening each awning is cut off. Is done. In addition, one of the a contacts of the relay Y is connected to a limit switch L connected in series.
1 to L7 are connected in parallel to form a self-holding circuit, and then any of the limit switches L1 to L7 until the automatic gear is switched to the parking position or the engine is stopped. Even when the switch is opened, the excitation state of the relay Y is maintained. Therefore, when operating each of the switches S <b> 2 to S <b> 13, there is no occurrence of an erroneous operation such as an unexpected sunshade opening / closing or a sunshade to be opened / closed does not drive.

When the automatic gear is at a position other than the parking position, the switch S2
When the switch S2 is turned to the right, the windshield 5a on the driver's seat side of the windshield 13 is supplied to the motor M1 only while the switch S2 is being energized.
Is supplied in the direction in which the sunshades close, but the awning 5a is
As shown in (1), when the vehicle descends to the boundary position obstructing the driver's view, the limit switch LA is released, the middle of the circuit connected from the 12V side of the power supply to the motor M1 via the switch S2 is interrupted, and the descent of the shade 5a is interrupted. . for that reason,
The switch S2 is not accidentally operated during driving, and the sight is not closed by the sunshade 5a.

Conversely, if the switch S2 is turned to the left, power is supplied to the motor M1 in the direction in which the shade 5a on the driver's seat side of the windshield 13 opens while the switch S2 is being energized. Keep moving in the opening direction.

Similarly, when the automatic gear is at a position other than the parking position, the switch S4 or the switch S9, which is a sub-switch, is tilted to the right, and the motor M3 is moved forward only while the switches S4 and S9 are energized. Power is supplied in the direction in which the awning 5b on the side of the glass 13 passenger seat closes, but when the awning 5b falls to a boundary position that blocks the driver's view as shown in FIG.
B is released, the circuit connected to the motor M3 from the 12V side of the power supply via the switches S4 and S9 is interrupted, and the descent of the shade 5b is interrupted. Therefore, the switches S4 and S9 are not accidentally operated during driving, and the visibility is not closed by the sunshade 5b.

Conversely, when the switches S4 and S9 are turned to the left, power is supplied to the motor M3 in the direction in which the sunshade 5b on the driver's seat side of the windshield 13 opens while the switch S4 is being energized. 5b continues to move in the opening direction.

That is, when the automatic gear is at a position other than the parking position, the awnings 5a and 5b can be independently controlled by substantially the same movement, and the awnings 5a and 5b are moved downward beyond the position where the awnings can be stopped at the backlight avoidance position. It is restrained from descending. However, the positions of the sunshades 5a and 5b to avoid backlight are not always the same depending on the physique of the person sitting on the driver's seat and the passenger's seat and other conditions. The conditions for opening the limit switches LA and LB that determine the positions of the sunshades 5a and 5b to avoid backlight can be mechanically changed by a mechanism (not shown), and the stop position for avoiding backlight can be arbitrarily set. It can be changed.

The opening and closing of the sunshade 7a on the driver's seat window side, the sunshade 2a on the passenger seat window side, the sunshade 8a on the driver's seat rear seat window side, the sunshade on the passenger seat side rear seat window side, and the sunshade 6 on the rear glass 14 are master switches. Switch S3
S5 to S8 or the switch S1 which is a sub-switch
If the corresponding switch among 0 to S13 is tilted to the right, the closing operation continues only while the switch is tilted to the right. Conversely, if the corresponding switch is tilted to the left, the operation of opening only while the switch is tilted to the left continues.

When the operation of the vehicle 11 is completed and the automatic gear is switched to the parking position, the power supply 12
Electric power is supplied from the V side to the electric motors M1 to M7 so as to move in a direction to close the corresponding awnings. That is, a limit switch LP consisting of an a contact is interposed in the middle of a circuit connected to the electric motors M1 to M7 so as to move from the 12V side of the power supply to the direction in which each awning is closed. If you switch to
Electric power is supplied to all of the electric motors M1 to M7 in a direction in which the limit switch LP is closed and all the awnings are closed. At this time, one line is branched from the 12V side of the power supply and power is supplied to each part of the electric motors M1 to M7. However, since a diode is interposed in each branch part in the forward direction,
When the switches S2 to S13 are operated, the current does not sneak into other portions of the electric motors M1 to M7 and does not malfunction.

When all the awnings are closed, the limit switches L8 to L14 connected in series are closed, and power is supplied to the relay Z. One of the contacts b of the relay Z is connected to the electric motors M1 to M7 from the 12V side of the power supply.
Is connected in series with the limit switch LP in the middle of the connection, and when all the awnings are closed, the power in the direction to close each awning is cut off. Note that one of the a contacts of the relay Z is connected to the limit switches L8 to L8 connected in series.
Since it is connected in parallel to L14, a self-holding circuit is configured, and thereafter, until the automatic gear is switched to a position other than parking or the engine is stopped,
The energized state of the relay Z is maintained even if any of the limit switches L8 to L14 is opened.

Incidentally, one of the b contacts of the relay Z is connected in series in the circuit for self-holding the relay Y.
Conversely, one of the b contacts of the relay Y is connected in series in the circuit for self-holding the relay Z. Therefore, when all the awnings are completely closed, the relay Y, which has been self-held until then, is released from the excited state and the self-holding is released. Conversely, when all the awnings are fully opened, the relay Z, which has been self-held until then, is released from the excited state and the self-holding is released.

The limit switches LA and LB are
One of the a contacts of the relay Z is connected to each of them in parallel. Therefore, when the vehicle 11 is traveling, the range in which the awning 5a on the driver's seat side of the windshield 13 and the awning 5b on the passenger's seat side of the windshield 13 shield the windshield 13 is limited to the range of the backlight protection. After the gear is switched to the parking position and all awnings are completely closed, the limit switches LA, L
The contacts a of the relay Z connected in parallel to each of the switches B are closed, and the open / close range of the sunshades 5a and 5b is set to the limit switch L.
A, LB will not be affected. That is, the vehicle 11
Are shades 5a and 5 by switches S2 and S4 during parking.
b can be freely opened and closed in any open / close state.

Further, in the direction in which the awning 7a on the driver's seat window side and the awning 2a on the passenger seat window side are closed, each of the circuits connected to the electric motors M2 and M4 via the switches S3 and S5 from the 12V side of the power supply. A contact of the relay Z is interposed. Therefore, the operation of closing the sunshade 7a on the driver's seat window side and the sunshade 2a on the passenger seat window side by the switch operation is limited only while the relay Z is energized. That is, when the automatic gear is at a position other than parking, such as when the vehicle 11 is running, the excited state of the relay Y is held by itself and the excited state of the relay Z is released. As a result, the middle of the circuit for transmitting power from the switches S3 and S5 to the direction in which the awning 7a on the driver's seat window side and the awning 2a on the passenger seat window side are closed by the contact a of the relay Z, and the switches S3 and S5 are operated. However, the awning 7a on the driver's seat window side and the awning 2a on the passenger seat window side do not close. Note that a switch S10 other than the switch S5 is interposed in the circuit connecting the 12V side of the power supply to the electric motor M4 in the direction in which the sunshade 2a on the passenger side window side is closed, so that the vehicle 11 is running. When the gear is at a position other than the parking position, even if the switch S10 is operated, the awning 2a on the passenger side window side does not perform the closing operation.

As described above, the multiplex power window 1 of the present embodiment is provided on the driver's seat side of the windshield 13, the driver's seat side, the front windshield 13, the passenger seat side, and the passenger seat window side, which are portions through which light is transmitted from outside to inside the vehicle. A sunshade 5 a, 7 a, 5 b, 2 a, 8 a which can shield each part of the rear glass 14, a sunshade (not shown), and a sunshade 6 which are not shown. Is opened and closed by an electrically controlled opening / closing means. When the automatic gear of the vehicle 11 to which each sunshade is mounted is switched to a position other than parking, light is transmitted from the outside of the vehicle to the inside of the car by the automatic releasing means. Each part is released.

In the multiplex power window 1 of the present embodiment, the sunshades 5a and 5b, which are portions of each sunshade that shield the opening provided with the windshield 13, open and close in the vertical direction. When the automatic gear of the vehicle 11 to which the vehicle 5a or 5b is mounted is located at a position other than the parking position, the range in which the opening can be blocked is limited to a position where the backlight is prevented from entering the view and the driving view is not blocked. Things.

Further, in the multiple power window 1 of the present embodiment, the sunshades 7a and 2a, which are portions of the sunshades that shield the openings provided with the side glasses 7, 2 of the driver's seat and the passenger's seat, are provided with the sunshades 7a. When the automatic gear of the vehicle 11 to which the vehicle 1 and 2a are mounted is located at a position other than the parking position, the vehicle 11 is not fully closed and closed.

Therefore, the multiplex power window 1 of the present embodiment is controlled by the electric control so that the sunshades 5a, 7a, 5b,

Moreover, the vehicle 1 can be operated without troublesome operations.
Just perform the operation to switch the automatic gear to a position other than parking, which is always done to drive 1
Each awning closed at the time of parking is opened, and a portion through which light is transmitted from the outside of the vehicle 11 to the inside of the vehicle is automatically opened, so that anyone can easily operate.

When the multiple power window 1 of the present embodiment is used during operation, the area of the sunshade that covers the opening provided with the windshield 13 prevents the backlight from entering the field of view while driving, and It is limited to a position where the view is not obstructed, and the opening provided with the windshield 13 is not erroneously obstructed so as not to hinder the driving.

Further, in the multiple power window 1 of the present embodiment, the sunshades 7a and 2a, which are portions of the sunshades that shield the openings provided with the side glasses 7, 2 of the driver's seat and the passenger's seat, are provided by the sunshades 7a. When the automatic gear of the vehicle 11 to which the vehicle 1 or 2a is mounted is in a position other than the parking position, the vehicle is not fully closed and does not close, and during driving, the visibility of the opening provided with the side glasses 7, 2 of the driver's seat and the passenger seat is provided. Because it is not hindered, it can be used safely while driving.

In the above description, a heat insulating means having improved heat insulating properties may be provided for each sunshade. If heat insulation means with improved heat insulation properties are provided for each awning, the speed at which heat from the direct sunlight received by each awning is transmitted to the inside of the vehicle by the heat insulation means will be reduced, and the effect of suppressing the rise in temperature inside the vehicle will be improved. This is higher than when no means is provided, which is preferable.

The heat insulating means may be constituted by providing a hollow layer inside a sunshade. FIG.
FIG. 4 is a cross-sectional view showing a first example of another heat insulating structure of a awning of a multiple power window according to an embodiment of the present invention.

The method of providing the hollow layer inside the sunshade includes:
As shown in FIG. 11, a sunshade may be formed by two glass plates 1a separated by a predetermined distance so that a hollow layer 1b is formed therebetween, but a plurality of bubble-like hollow layers are formed inside the sunshade. May be provided. The interior of the hollow layer may be vacuum, but may be filled with various gases such as air. In any case where the hollow layer is provided inside the sunshade by any method, the heat insulating property can be sufficiently improved by using the same material as the ordinary window glass without using a material having a special heat insulating effect.

As described above, if the heat insulating means is formed by providing the hollow layer inside the sunshade, the same material as that of a normal window glass can be used as the material for the sunshade. The speed at which heat from direct sunlight is transmitted into the vehicle can be reduced.

Further, as shown in FIG. 12, the heat insulating means is provided with a reflective film 1c on the outer surface of the glass plate 1a serving as a sunshade.
May be provided. FIG. 12 is a cross-sectional view showing a second example of another heat insulating structure of the awning of the multiple power window according to the embodiment of the present invention.

As shown in FIG. 12, if a reflective film 1c is provided on the outer surface of a glass plate 1a serving as a sunshade, direct sunlight is reflected without entering the vehicle 11 and the temperature inside the vehicle 11 rises. Is suppressed. Note that the reflection film 1c is not limited to reflecting light in all wavelength ranges, but may transmit a part of visible light.

As described above, if the heat insulating means is constituted by providing the reflection film 1c on the outer surface of the glass plate 1a to be the awning, the direct sunlight is reflected, and the light blocked by the awning raises the temperature of the awning itself. Since this is suppressed, the thickness of the awning itself can be reduced without sacrificing the heat insulating effect.

In addition, as shown in FIG. 13, the heat insulating means may be constituted by incorporating a solar cell plate 1d on the outer surface of a glass plate 1a serving as a sunshade. FIG. 13 is a cross-sectional view showing a third example of another heat insulating structure of the awning of the multiple power window according to the embodiment of the present invention.

As described above, if the heat insulating means is constructed by incorporating the solar cell plate 1d on the outer surface of the glass plate 1a serving as a sunshade, part of direct sunlight is converted into electric power without being converted into heat. The rise in the temperature of the sunshade is reduced by the amount of direct sunlight converted to the amount of heat, and the amount of heat entering the vehicle from outside the vehicle can be reduced. The position where the solar cell plate 1d is incorporated in the awning is not limited to the outer surface of the awning, but may be inside or on the back.

When the solar cell plate 1d is incorporated in the glass plate 1a for heat insulation, the air conditioning equipment 21 as shown in FIG. 11 may be provided.
FIG. 14 is an explanatory diagram showing another example for maintaining the in-vehicle environment.

The air conditioner 21 shown in FIG. 14 includes an air conditioner 22, a controller 23, and a storage battery 24. The air conditioner 22 is a part for making the environment inside the vehicle comfortable, such as ventilation, dehumidification, cooling, and air purification, and operates with electric power. The electric power generated by the solar cell plate 1d is transmitted to the air conditioner 22 via the controller 23.
Is connected. The controller 23 includes an air conditioner 22
The surplus power of the power generated by the solar cell plate 1d is accumulated in the storage battery 24 in the process of performing air conditioning in the vehicle by the solar battery, and when the power is insufficient, the power supply source is switched to the storage battery 24. This is a part for effectively utilizing the electric power generated by the battery plate 1d for air conditioning in the vehicle.

As described above, if the interior of the vehicle 11 is air-conditioned by the electric power generated by the solar cell plate 1d used for heat insulation of the sunshade, the flow of heat into the vehicle from outside the vehicle 11 is simply prevented. Not only does it prevent air, it also has a function to make the environment inside the vehicle comfortable, such as ventilation, cooling, or air cleaning, which replaces the air inside the vehicle with outside air, by using part of the energy of direct sunlight converted into electric power. Since the electric power generated by direct sunlight increases as the intensity of direct sunlight increases, a comfortable interior environment can always be maintained regardless of the intensity of direct sunlight. In addition, the air conditioning means is a means for replacing the air inside the vehicle with outside air to make the environment inside the vehicle comfortable, such as ventilation, cooling, or air cleaning, and may perform all of these ventilation, cooling, or air cleaning. However, any of these ventilation, cooling, air cleaning, and the like may be performed.

In addition, in the above description, the material of each awning is not particularly limited, and materials having a reduced light transmittance such as sunglasses, materials that completely block light such as metal, In addition to these properties, a material that enables bulletproofing, such as bulletproof glass, may be used. A single opening may be provided with a plurality of awnings made of a plurality of types of materials so as to overlap each other, so that each of the awnings can be independently opened and closed.

In the above description, the power source of the opening / closing means for each awning is the electric motors M1 to M7. However, the power source is not necessarily limited to the electric motors.
An air cylinder or the like may be used.

In the above description, only the sunshade 5 is limited to blocking to the optimum position for avoiding backlight while driving the vehicle 11, but other sunshades are limited to the optimal position for avoiding backlight. It may be limited to the shielding of. In this way, if it is limited to shielding to the optimal position as a backlight avoidance, each awning prevents backlight entering from the opening of the shielding destination from entering the field of view due to switch operation error and from the position that does not block the field of view It is preferable because it can be prevented from descending and can be used as a sunshade to avoid backlighting with confidence.

Furthermore, in the above description, it is only the awning 5 that is divided into a plurality of parts and the movements are independent of each other. However, the other awnings are divided into a plurality of parts and the movements are independent of each other. I do not care. If the sunshade is divided into multiple parts and their movements are independent of each other, only the part that is exposed to direct sunlight can be carefully selected and shielded, so the temperature inside the vehicle rises without unnecessarily reducing the illuminance inside the vehicle Can be prevented, and even if someone is left in the vehicle at the time of stopping or the like, the person left in the vehicle does not feel uncomfortable. In addition,
The number of divisions for each sunshade is not particularly limited, but the greater the number of divisions, the more comfortable it is because the area of windows that must be shielded to prevent direct sunlight from entering the car is not increased unnecessarily. The interior environment can be formed.

In the above description, in order to determine that the vehicle is parked, instead of the automatic gear being at the parking position, the limit switch LP is closed when the side brake is released, and the vehicle is being driven. The same effect can be obtained by closing the limit switch LQ when the side brake is released instead of the automatic gear being in the drive position for the determination. In particular, the vehicle 11 to which the multiple power window according to the present embodiment is mounted is an automatic vehicle.
If the means for determining whether the vehicle is parked or driving is a side brake, the present invention is not necessarily limited to an automatic vehicle.

In addition, in the above description, the awnings 2a, 7
a, 8a, and awnings (not shown) shield portions from which light passes from the outside to the inside of the corresponding vehicle from above, and the awnings 5 and 6 from above. The closing direction of each awning Is not necessarily limited to such a direction, and may be closed from other directions. For one opening, sunshades of a plurality of types of materials may be independently opened and closed from different directions. For example, as a awning of the windshield 13, a awning 5 that is closed downward from above is made of a material through which light does not pass, and a awning that is closed upward from below is separately provided. The light transmittance may be reduced.
