Description

Detailed Description of the Invention

[0001]

The present invention relates to power window regulators. More specifically, the present invention relates to a power window regulator capable of remotely controlling a side window, a roof, etc. of an automobile and selecting the opening / closing amount thereof.

[0002]

2. Description of the Related Art A conventional power window regulator is
For example, as disclosed in Japanese Utility Model Laid-Open No. 2-68981, the position sensor installed in the door panel detects the opening of the window glass, and the indicator that displays this is used by the driver such as the driver's seat instrument panel. It is known that it is arranged at such a position that it can be seen while facing forward.
In this power window regulator, it is necessary to keep pressing the open / close switch to a desired opening.

On the other hand, in the power window regulator disclosed in Japanese Utility Model Laid-Open No. 63-104583, it is not necessary to continue to press the open / close switch, but the switch operation can be selected only when the window glass is fully opened or fully closed. It is necessary to operate the stop switch separately in order to stop at once. That is, the window glass cannot be stopped at an arbitrary opening with one touch.

[0004]

As described above, in the conventional power window regulator, in order to stop the window glass at a desired opening degree, the open / close switch is pushed to the stop position or the open / close switch is operated. After the operation, it is necessary to confirm the opening degree by looking at the window glass itself, and stop the operation again with the switch. In other words, the driver is greatly troubled by work other than the driving operation of the automobile.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a power window regulator capable of moving a window glass or the like to a desired opening degree with one touch by an extremely compact system.

[0006]

A power window regulator of the present invention is an open / close switch for selecting and instructing a stop position of a window, a drive section which operates based on the open / close switch signal, and a pull drive by the drive section. Control cable, a carrier plate fixed to the control cable and fixed to a window, and a guide rail attached to a door panel for guiding the movement of the carrier plate, wherein the drive unit outputs the electric motor. It is characterized in that it has detection means for rotating with the shaft and detection means for detecting the amount of rotation of the detection means. And, the detected means,
The detection means can be composed of a disk-shaped magnetic body having a large number of slits along the circumferential direction, and the detection means can be composed of a proximity switch.

[0007]

According to the power window regulator of the present invention, when the opening / closing switch (hereinafter, simply referred to as a switch) is used to select a predetermined opening, an opening signal is transmitted from the switch to the control box. In the control box, the motor of the drive unit is operated by the opening signal and the rotation amount signal of the drive unit is received from the rotation amount detector of the drive unit. Then, when the rotation of the drive unit reaches the rotation amount corresponding to the opening of the window glass set by the opening signal of the switch, the operation of the motor of the drive is stopped.

The driving unit moves the window glass by driving the control cable.

Therefore, the driver of the vehicle can move the window to a desired opening degree by one-touch operation with the switch, and can concentrate on driving the vehicle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a window regulator of the present invention will be described with reference to the attached drawings.

FIG. 1 is a schematic front view showing an embodiment of a window regulator of the present invention, FIG. 2 is a perspective view before assembly showing an embodiment of a drive unit in FIG. 1, and FIG. 3 is an opening / closing switch in FIG. It is a perspective view showing an example.

In FIG. 1, reference numeral 1 is a window regulator, which comprises a drive unit 2, a control box 3, an open / close switch 4 and a regulator unit 5.

The regulator section 5 is a known one. That is, the control cable 6 is routed in a loop shape via the drive unit 2, and the carrier plate 7 is fixed to a part of the control cable 6. The carrier plate 7 is fixed to the window glass W, and is guided by a guide rail 8 attached to the door panel P so that it can move up and down.

When the operator operates the open / close switch 4, the drive unit 2 pulls and drives the control cable 6 to move the carrier plate 7 along the guide rail 8 to open / close the window glass W.

The details of the drive unit 2 are shown in FIG. That is, a cable drum 10 for winding up and feeding out the control cable 6 is connected to the output shaft end of the electric motor 9 which is a driving force source.

A plate 12 made of a magnetic material (for example, iron) having a large number of slits 11 in the circumferential direction is fixed to the upper end surface of the cable drum 10. These 10 and 12 are housed in the drive unit 2, and a housing cap 13 is covered. The slit 11 is provided on the housing cap 13.
The proximity switch 14 is attached so as to correspond to. With this proximity switch 14, the number of slits 11 that pass with the rotation of the plate 12 can be measured, and the rotation amount of the cable drum 10 can be detected.
As a result, the winding amount of the control cable 6, that is, the moving amount of the window glass W can be detected.

On the other hand, FIG. 3 shows the open / close switch 4. This open / close switch 4 is a sliding button
15 is designed to slide continuously along a guide groove 17 formed in the switch body 16, and a scale corresponding to the opening of the window glass W (0, 10, 20, ... 100%, etc.)
Is displayed. Then, a signal such as a voltage value at the position where the button 15 is set is sent to the control box 3.

In the control box 3, the opening signal from the opening / closing switch 4 is detected to drive the electric motor 9 of the drive unit 2. Accordingly, when the plate 12 rotates via the output shaft of the electric motor 9 and the cable drum 10, the proximity switch 14 detects the rotational displacement of the plate 12 and feeds back its position signal to the control box 3. Then, the rotation direction and the stop position of the electric motor 9 of the drive unit 2 can be automatically determined by comparing the opening signal input in the initial stage with the position signal.

In this way, the window glass W can be moved to the stop position designated by the open / close switch 4.

As described above, the button 15 of the open / close switch 4
It can be operated continuously, so to speak, so to speak, it is very easy for the driver to operate. In addition, for example, if the switch body 16 is colored differently such that the portion that is 50% open or more is red and the portion that is less than 50% open is blue, it is convenient because the opening / closing direction can be seen at a glance. Further, in combination with the analog operation, it becomes possible to set the window glass W to a desired opening degree without having to watch the open / close switch 4. It will be even more convenient if the open / close switch 4 is installed in a position such as an instrument panel of a car where the driver can see the vehicle while facing forward.

The present invention is not limited to an open / close switch that can be continuously operated, and corresponds to a plurality of predetermined openings (0%, 25%, 50% ... 100%), for example. It may be an open / close switch provided with each push button and operated so to speak digitally.

In this embodiment, the proximity switch 14 is used as the detecting means, but the present invention is not limited to this, and for example, the plate with the slit 11 is used.
It is also good to adopt a photoelectric switch with 12, or
Other types of optical sensors, magnetic sensors, contact potentiometers, rotary encoders, resolvers, etc. can be used. In short, any drive can be used as long as it can be compactly stored in the drive unit.

[0023]

According to the window regulator of the present invention, the window glass can be set to a desired opening degree by a one-touch operation.

Furthermore, since it is not necessary to provide a separate sensor on the door panel or the like, and the construction is extremely compact, it is easy to assemble and maintain.
Cost savings.
