Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle power window device suitable for use in an automobile having a sliding door.

[0002]

2. Description of the Related Art Recently, many automobiles are equipped with a power window device. In this case, the elevating mechanism of the window glass and the switch for controlling the elevating mechanism are usually provided on the door side. In passenger cars, etc., where the door is attached to the vehicle body by a hinge, power is supplied to the electrical equipment installed inside the door by a wire harness that passes near the hinge. The same operation can be performed both when it is closed and when it is closed.

However, in a vehicle employing a sliding door such as a rear door in a car for passengers and passengers, the sliding door has a structure not suitable for passing a wire harness. Therefore, a power feed switch that connects the sliding door side with the contact point is used (see Japanese Utility Model Publication No. 64-356 as an example of this structure).

This will be described with reference to FIG. Reference numeral 1 is a vehicle body, and 2 is a slide door attached to the vehicle body 1 so as to be openable and closable. A terminal 3 connected to an ignition terminal of a main switch (not shown) is provided on the vehicle body 1 side. Reference numerals 4 and 5 are terminals connected to the main switch of the power window. A vehicle body side power supply switch 6 is provided on the vehicle body 1, and a slide door 2 at a portion facing the vehicle body side power supply switch 6
A door side power supply switch 7 is provided in the.

The vehicle body side power supply switch 6 is provided with a contact 8 connected to the terminal 3 and contacts 9 and 10 connected to the terminals 4 and 5, and one door side power supply switch 7 is provided with the contacts 8 and 8, respectively. Contacts 11, 12, 13 are provided so as to correspond to 9, 10. These corresponding sets of contacts are in contact with each other when the sliding door 2 is closed with respect to the vehicle body 1 and are electrically connected, and are separated when the sliding door 2 is opened and electrically disconnected. ..

Reference numeral 14 is a power window switch provided on the slide door 2. This power window switch 14
Is provided with three terminals 15, 16 and 17, and these terminals 15, 16 and 17 are connected to the contacts 11, 12 and 13 of the door side power supply switch 7, respectively. The fixed contact 19 of the changeover switch 18 is connected to the terminal 15 of the power window switch 14, and the fixed contact 20 of the changeover switch 18 is connected to the terminal 16. Further, the fixed contact 22 of the changeover switch 21 is connected to the terminal 17, and the fixed contact 23 of the changeover switch 21 is the terminal.
Connected to 15.

The changeover switch 18 and the changeover switch 21 are interlocked with each other.
A power window motor 28 as a window glass lifting mechanism is connected to the movable contacts 24 and 25 of 21 via terminals 26 and 27. By this connection, the changeover switch that works together
Power window motor by switching 18 and selector switch 21
Since the polarity of the power supply voltage applied to 28 is reversed, the mechanism linked to this power window motor 28 causes the window glass to rise or fall.

In the conventional power window device for a sliding door having such a structure, the power supplied to the power window motor 28 is supplied from the vehicle body side via the vehicle body side power supply switch 6 and the door side power supply switch 7. Since it is given, there is no problem when the slide door 2 is closed to the vehicle body 1, but there is a problem that the window glass cannot be moved up and down when the slide door 2 is opened as when the vehicle is stopped. The invention described in the above-mentioned publication does not solve this problem because it merely shows the connection structure of the power supply line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 by assigning the same reference numerals to the same members as in FIG. In the circuit of the present invention, both the vehicle body side power supply switch 6 and the door side power supply switch 7 are increased in number of contacts one by one, and the added contacts 29 and 30 are grounded (vehicle body grounded. The same applies hereinafter). Then, when the slide door 2 is closed, the projection 31 hits the vehicle body 1 and is pushed by the slide door 2.
A door switch 35 is provided, in which a movable contact 32 integrated with the protrusion 31 closes between the fixed contacts 33 and 34 and is turned on. The door switch 35 has a structure in which when the slide door 2 is opened, the projection 31 is projected by the urging force of a spring (not shown), and the movable contact 32 is separated from the fixed contacts 33 and 34.

One fixed contact 33 of the door switch 35 is grounded, and the coil 37 of the relay 36 is connected between the other fixed contact 34 and the contact 11 of the vehicle body side power supply switch 7. In the relay 36, the movable contact 38 comes into contact with the fixed contacts 39 and 40 to turn on when the coil 37 is excited.
41, a switching contact 45 in which the movable contact 42 contacts the grounded fixed contact 43 when the coil 37 is not excited, and the movable contact 42 contacts the fixed contact 44 when excited, and exactly the same as the switching contact 45. A switching contact 49 is provided in which the movable contact 46 contacts the grounded fixed contact 47 when the coil 37 is not excited and the movable contact 46 contacts the fixed contact 48 when excited. The fixed contact 44 of the switching contact 45 is connected to the contact 12 of the door side power supply switch 7, and the fixed contact 48 of the switching contact 49 is connected to the contact 13 of the door side power supply switch 7.

The internal connection of the power window switch 14 and the connection circuit of the power window motor 28 are the same as those shown in FIG. In the present invention, the three terminals 15, 16, 17 of the power window switch 14 are not directly connected to the contacts 11, 12, 13 of the vehicle body side power supply switch 7, but are switched to the normally open contact 41 described above. The connection is made through the contact 45, the switching contact 49, and the like. That is, the diode 50 is connected between the fixed contact 40 of the normally open contact 41 and the terminal 15. A capacitor 51 as a power supply device to be charged is connected between the cathode side of the diode 50 and the ground circuit. Between the movable contact 42 of the switching contact 45 and the terminal 16 of the power window switch 14, and the movable contact of the switching contact 49.
46 and the terminal 17 of the power window switch 14 are directly connected to each other.

The vehicle power window device of the present invention thus constructed operates as follows. When the ignition switch is turned on and the ignition is turned on when the slide door 2 is closed with respect to the vehicle body 1, since the door switch 35 of the slide door 2 is turned on, the coil 37 of the relay 36 is energized and excited. The normally open contact 41, the switching contact 45, and the switching contact 49 are activated, and the current flows through the diode 50 in the capacitor 51. As a result, the capacitor 51 is charged. The movable contacts 42 and 46 of the changeover switches 45 and 49 are switched to the fixed contacts 44 and 48 from the fixed contacts 43 and 47, which have been in contact with each other by the excitation of the coil 37, so that the terminals 15 and 16 of the power window switch 14, 17
Are electrically connected to the vehicle body side power supply switch 6, respectively. As a result, when the slide door 2 is closed, the same operation as that of FIG. 2 is performed.

Next, since the door switch 35 is turned off when the sliding door 2 is open, the coil of the relay 36 is
37 is not excited. As a result, the normally open contact 41 is turned off, and the movable contacts 42 and 46 of the switching contact 45 and the switching contact 49 come into contact with the fixed contacts 43 and 47 which are grounded. As a result, the capacitor 51 serves as the power source of the power window motor 28. Therefore, if the power window switch 14 is operated in this state, the same function as when the slide door 2 is closed can be obtained as long as the electric energy accumulated in the capacitor 51 is present. When operating in this way, the diode 50 acts to prevent backflow from the capacitor 51 to the ignition line when the ignition is off with the sliding door closed.

In the embodiment described above, the capacitor 51 is used as the power supply device to be charged, but it goes without saying that a device other than the capacitor, for example, a rechargeable battery can be used when the present invention is realized.

[0018]

Since the present invention is a vehicle power window device constructed as described above, it is possible to open and close a window glass when a sliding door which cannot be operated conventionally is opened. This has the effect of being able to perform exactly the same as when closing the.
