DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a power window control device for an automobile.

[0002]

2. Description of the Related Art Conventionally, in a power window control apparatus for an automobile, as shown in US Pat. No. 5,245,258, a motor for opening and closing a windshield and a rotation of the motor are detected and detected in response to the detection. There is a type in which a sensor unit that outputs a signal and an electronic control device that drives a motor in accordance with a detection signal from the sensor unit are housed in a housing of the motor.

Here, the motor, the sensor unit, and the electronic control unit are housed between the outer plate and the inner plate of the door, respectively. A waterproof member is provided for protecting the unit, the electronic control unit, and the entire electric system for supplying power to the motor and the electronic control unit.

[0004]

However, the above-described power window control device requires a waterproof member for the motor, a waterproof portion for the sensor unit and the electronic control device, and a waterproof portion for the connection portion between the motor and the sensor unit. is there. Therefore, there is a problem that the configuration becomes complicated as a waterproof member of the power window control device.

On the other hand, there is an electronic control device which is disposed on the inner side of a door inner plate and does not require a waterproof portion of the electronic control device. However, a waterproof portion for a motor and a sensor unit is required. Needless to say, in addition to the waterproof portion of the wire harness between the sensor unit and the electronic control unit, a waterproof portion is also required at a connection portion of the wire harness to the sensor unit.

[0006] In view of the above, an object of the present invention is to provide a power window control device in which a waterproof member is simplified.

[0007]

According to the present invention, in order to achieve the above object, according to the first aspect of the present invention, an outer plate (2) is provided.
A power window control device applied to an automobile door (10) having an inner plate (0) and an inner plate (30), disposed between the outer plate and the inner plate to open and close the windshield (40). (62) and a sensor (71) disposed between an outer plate and an inner plate and detecting rotation of the motor.
a, 71b) for outputting a detection signal in response to detection by the sensor, and a motor disposed through an opening (31) formed in the inner plate, which is disposed on the vehicle interior side of the inner plate. A drive unit (80) connected to the sensor unit and driving the motor in accordance with the detection signal output from the sensor unit; a motor waterproof unit (63) formed to cover the motor and waterproof the motor; A waterproof unit (63, 90) having a sensor unit waterproof section (90) formed between the motor and the opening to cover the sensor unit and waterproof the sensor unit.

As described above, since the sensor unit waterproof portion formed between the motor and the opening so as to cover the sensor unit and waterproof the sensor unit is employed, the waterproof member of the power window control device is the above-mentioned sensor. Since only the waterproof member having the unit waterproof portion and the motor waterproof portion is required, the simplification can be achieved.

According to the second aspect of the present invention, since the opening is formed in such a size that the sensor unit can be incorporated from the interior side of the inner plate into the sensor unit waterproof portion, the sensor unit can be mounted. Can be easily incorporated.

Further, according to the third aspect of the invention, the sensor unit may be positioned so as to penetrate the opening.

Here, in the invention described in claim 4, the sensor unit and the driving device each have a printed board (71, 82), and the printed board of the sensor unit is positioned so as to pass through the opening. And it is connected to the printed circuit board of the drive device. This eliminates the need for a wire harness for connecting between the sensor unit and the driving device.

Further, in the invention according to claim 5, the sensor unit may be connected to the driving device by a wire harness (110), and the sensor unit waterproof portion may waterproof the wire harness together with the sensor unit.

Further, in the invention described in claim 6, the sensor unit waterproof portion may be formed so as to extend from the motor to the opening.

Further, in the invention according to claim 7, the sensor unit has a power supply connector (72) for supplying a driving power for the motor. This allows the sensor (71
a, 71b), as well as the electrical system for supplying drive power to the motor can be waterproofed together.

Further, in the invention according to claim 8, the sensor unit waterproof portion (90) is formed of an elastic member, and the motor (6) is closed so as to cover the opening (31).
Since it is arranged from 2) on the inner side of the vehicle interior of the inner plate, rainwater does not enter the vehicle interior side of the inner plate (30) from the opening. Further, since the opening can be closed by the elastic force of the elastic member, a member for closing the opening is not required.

In the present invention, the sensor may detect the rotation of the motor without contacting the motor, as will be described in an embodiment to be described later. Thereby, the assemblability to the motor side in the sensor unit can be improved. Here, for example, a magnet is arranged on a part of the rotating member of the motor so that the magnet rotates in accordance with the rotation of the motor, and a Hall sensor is employed as a sensor, and the Hall sensor is mounted on the magnet. You may make it oppose by contact.

By the way, the reference numerals in parentheses of the above-mentioned means are examples showing the correspondence with the concrete means described in the embodiments described later.
