BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power window device for automatically opening and closing a window member such as a window glass.

[0002]

2. Description of the Related Art A power window device is a device for operating a window opening / closing mechanism by operating a predetermined switch, thereby moving a window member in an opening direction or a closing direction with respect to a window opening. Although it can be opened and closed by a simple switch operation without the need for a switch, it is used in many vehicles,
After the switch operation is performed, the window member automatically moves.When the window member is moved in the closing direction, foreign matter such as a body or clothes is moved between the window member and the window opening. Care must be taken not to get caught.

For this reason, conventionally, for example, Japanese Utility Model Laid-Open No. 2-7978
As disclosed in Japanese Unexamined Patent Application Publication No. 8 (1994), when the window opening / closing mechanism receives an operation load equal to or more than a predetermined value during the closing operation of the window opening / closing mechanism, it is determined that foreign matter has been trapped and the window opening is fully opened. The opening / closing mechanism is opened (reversed operation) to ensure safety.

[0004]

However, when an operation load of a predetermined value or more is received and a foreign object is detected, the window opening / closing mechanism is opened (reversed operation) until the window opening is fully opened. Then, the following problem occurs. That is, when foreign matter is caught in the normal window, the clogging can be sufficiently released by once opening the window member as described above,
It is not necessary to fully open the window member to release the entrapment, and the entrapment was originally intended to close the window member. However, opening the window member fully is contrary to this, forcing the window operator to perform the window closing operation again (first problem). In general, the operation load during the closing operation of the window opening / closing mechanism is not uniform. When the opening of the window opening is large, the load is relatively low, whereas the closing operation of the opening of the window opening is small. Immediately before, the window member starts to slide on the seal member at the window opening, so that the load tends to increase suddenly, and the degree varies depending on various factors such as temperature, humidity, and assembly error. Therefore, when the window opening / closing mechanism is opened (reversed operation) when a foreign object is detected by receiving an operation load of a predetermined value or more as described above, the operation load threshold value for the reversal operation is used. When the window opening / closing mechanism is activated until just before the closing operation is completed, the operation load is set to the above value even if no foreign matter is caught when the window opening / closing mechanism is operated just before the closing operation is completed. It is also conceivable that the window opening / closing mechanism may open beyond the threshold value.

On the other hand, as disclosed in Japanese Patent Application No. 4-108852, which is a prior application filed by the present applicant, a window opening is smaller than a predetermined opening which is almost fully closed. If the window opening / closing mechanism is configured to continue the closing operation even when the window opening / closing mechanism receives an operation load of a predetermined value or more when the window member moves in the closing direction to the opening degree range, the window opening / closing mechanism is inadvertently activated. The opening operation can be prevented.

In this case, even if foreign matter is caught, the reversing operation of the window opening / closing mechanism is not performed in the small opening area, but the window member actually moves in the closing direction. In such a case, it is easy to detect the possibility of foreign matter being pinched before reaching the small opening area, and to avoid this, so that safety is not impaired. However, when the window member stopped in the small opening area is moved in the closing direction, such as when the window member is slightly opened for ventilation in the passenger compartment, foreign matter is trapped. It is also conceivable that the movement of the window member in the closing direction is started without noticing that the window member is moving. Therefore, in setting the predetermined opening of the window opening that defines the small opening region, it is necessary to set the predetermined opening to a sufficiently small opening so that foreign objects, particularly fingers, are not pinched.

However, if the predetermined opening is set to a sufficiently small opening as described above, the reversing operation is performed until immediately before the completion of the closing operation at which the operation load of the window opening / closing mechanism becomes large. However, there is a problem that the window opening / closing mechanism may be opened (second problem).

The present invention has been made in view of the above circumstances, and provides a power window device capable of both releasing a foreign object from being caught and closing a window in accordance with the intention of a window operator. As a first object (corresponding to the above-mentioned first problem). Another object of the present invention is to provide a power window device which can prevent an inadvertent opening operation of a window opening / closing mechanism while preventing the occurrence of pinching of foreign matter. Corresponding).

[0009]

SUMMARY OF THE INVENTION A power window device according to the present invention is configured such that when an operation load of a predetermined value or more is applied during a closing operation of a window opening / closing mechanism, the window member is once moved in a direction to open by a predetermined amount. By moving in the closing direction again, the first object is achieved.
That is, a window opening / closing mechanism for moving the window member in the opening direction or the closing direction with respect to the window opening by a predetermined switch operation, and the window opening / closing mechanism applies an operation load of a predetermined value or more during the closing operation of the window opening / closing mechanism. Operation control means for controlling the operation of the window opening / closing mechanism so as to once move the window member in the opening direction when received and then move it again in the closing direction when received. is there. Further, in the power window device according to the present invention, when the window member stopped within the small opening area is moved in the closing direction, the window member is first moved to the outside of the small opening area in the opening direction and then closed. By moving in the direction, the small opening area can be set wider, thereby achieving the second object.

[0010] In one of the power window devices aiming at achieving the second object, the operation control means further comprises a small opening region in which the opening of the window opening is equal to or less than a predetermined opening close to full closure. When moving the window member stopped in the closing direction, the window opening / closing mechanism is operated so as to move the window member in the opening direction to the outside of the small opening degree region and then to move the window member in the closing direction. Is controlled. In another power window device that achieves the second object, the operation control means further includes a small opening region in which the opening of the window opening is equal to or less than a predetermined opening that is close to fully closed. When the window member moves in the closing direction to the inside, the window opening / closing mechanism continues to move in the closing direction even when the window opening / closing mechanism receives an operation load equal to or greater than the predetermined value, and the window opening / closing mechanism moves within the small opening degree region. When moving the window member stopped in the closing direction, the operation of the window opening / closing mechanism is performed such that the window member is moved in the opening direction to the outside of the small opening area once and then moved in the closing direction. It is characterized by being controlled.

The above-mentioned "window member" is typically a window glass, but is not limited to this, and includes a wide variety of members that open and close a window opening.

[0012]

As described above, in the present invention, when the window opening / closing mechanism receives an operation load of a predetermined value or more during the closing operation of the window opening / closing mechanism, the window member is once opened in the opening direction by a predetermined amount. After moving the window member in the closing direction, a foreign object such as a body or clothes is caught between the window member and the window opening by moving the window member in the opening direction by a predetermined amount. Can be prevented, thereby ensuring safety, and moving the window member in the closing direction again after the predetermined amount of movement in the opening direction. The closing operation of the window member to be performed is automatically performed, and the window operator must perform the window closing operation again according to the intention of the window operator. It is possible to eliminate the complexity of the operation that it is not. Therefore, according to the present invention, it is possible to perform both of the release of the foreign object and the window closing operation that matches the intention of the window operator.

In the present invention, when the window member moves in the closing direction to a small opening region in which the opening of the window opening is less than a predetermined opening close to full closure, the window opening / closing mechanism is not less than a predetermined value. Since the closing operation is continued even when an operation load is received, it is possible to prevent the window opening / closing mechanism from being opened carelessly. In this case, in the small opening region, the reversing operation of the window opening / closing mechanism is not performed even if foreign matter is caught, but when the window member is actually moving in the closing direction, the small opening region is set. Since it is easy to detect and avoid the possibility that foreign matter will be trapped before reaching, safety is not impaired by this.

Further, in the present invention, when the window member stopped within the small opening area is moved in the closing direction, the window member is first moved in the opening direction outside the small opening area and then closed. Therefore, it is easy to detect the possibility of foreign matter being pinched while the window member moves in the opening direction to the outside of the small opening region, and to easily avoid this. For this reason, in setting the predetermined opening of the window opening defining the small opening region, even if the predetermined opening is set to a relatively large opening, safety is not impaired, and the predetermined opening is set to the window. The opening can be set to a relatively large opening before the operating load of the opening / closing mechanism becomes excessive.

Therefore, according to the present invention, it is possible to prevent the inadvertent opening operation of the window opening / closing mechanism while preventing occurrence of pinching of foreign matter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view showing an embodiment of the power window device according to the present invention, and FIG. 2 is a block diagram thereof.

As shown in FIG. 1, a power window device 1
0 is provided on the vehicle door 12.

The vehicle door 12 includes a door body 14 composed of an outer panel and an inner panel,
A door glass 16 (window member) is provided in the door body 14 so as to be able to move up and down.

The power window device 10 raises and lowers the window glass 18 by operating a power window switch 20 (see FIG. 2) (that is, the window glass 18 is opened by the window main body 14 and the door sash 16). A window opening / closing mechanism 24 (moving the opening / closing direction with respect to the section 22), and a control unit 26 (see FIG. 2) (operation control means) for controlling the operation of the window opening / closing mechanism 24. .

The window opening / closing mechanism 24 is fixed to an inner panel of the door body 14 via a mounting bracket 28 and guides the window glass 18 up and down.
0, a slider 32 fixed to the lower end of the window glass 18 and capable of moving up and down along the guide member 30 by engaging with the guide member 30; and a conductive member such as a wire (shown in FIG. ), And drives the slider 32 up and down along the guide member 30.
4 and an encoder 36 attached to the drive motor 34
(See FIG. 2).

The control unit 26 raises or lowers the window glass 18 by rotating the drive motor 34 forward or backward according to an input signal from the power window switch 20, and also controls the window glass 18 according to an input signal from the encoder 36. Is detected.

As shown in FIG. 3, the control unit 26 receives a fully closed signal (a signal for raising the window glass 18 until the window opening 22 is fully closed) from the power window switch 20 (see FIG. 3). In step S1), the following control is performed on the window opening / closing mechanism 24 according to the opening degree of the window opening 22.

First, when the opening of the window opening 22 is in a sufficiently large opening region (the dimension between the upper edge of the window glass 18 and the lower edge of the upper portion of the door sash 16 is d)
Then, for example, when d> 200 mm), only the closing operation is performed by the window opening / closing mechanism 24 (that is, the drive motor 34 is rotated forward to raise the window glass 18) (step S2, S8).

Next, although the opening of the window opening 22 is not so large as in the large opening region, the opening of the window opening 22 is a predetermined opening close to fully closed (for example, when d = 10 mm).
When it is within the larger medium opening degree region (when the determination in step S3 is YES), the following inversion operation control is performed. That is, the window opening / closing mechanism 24
The window opening / closing mechanism 24 is set to a predetermined value (the minimum load among the operating loads considered to be generated when a foreign object such as a body or clothing is caught between the window glass 18 and the window opening 22) during the closing operation of the window. When the above operating load is received,
The closing operation is stopped and switched to the opening operation, whereby the window glass 18 is once lowered by a predetermined amount (for example, 10 mm), and then switched to the closing operation again to raise the window glass 18 (step S4). , S6, S
7, S8). Of course, when the operation load of not less than the predetermined value is not received, the window opening / closing mechanism 24 is made to perform only the closing operation (steps S4 and S8).

Further, in the small opening region where the opening of the window opening 22 is equal to or less than the predetermined opening (when the determination in step S3 is NO), the following operation control is performed. I have. That is, the window opening / closing mechanism 2
When the opening of the window opening 22 changes from the middle opening region to the small opening region due to the rise of the window glass 18 during the closing operation of the window 4, the window opening / closing mechanism 24 receives an operation load equal to or more than the predetermined value. In this case, the window opening / closing mechanism 24 performs only the closing operation without performing the reversing operation control (steps S5 and S8). on the other hand,
When moving the window glass 18 stopped in the small opening degree region in the closing direction, the window opening / closing mechanism 24 is once operated to open the window glass 18 by a predetermined amount (for example, 10 mm) regardless of the magnitude of the operation load. After the lowering, the window opening and closing mechanism 24 is closed to raise the window glass 18 (steps S5, S6, S).
7, S8). That is, the window opening / closing mechanism 24 is closed after the window glass 18 is lowered to the outside of the small opening area (that is, to the inside of the middle opening area).

The reason why the above-mentioned "predetermined opening degree close to fully closed" is set to a relatively large value, for example, d = 10 mm is as follows.
This is because the reversing operation control is terminated before the window glass 18 starts slidingly contacting the sealing member of the window opening 22, thereby preventing the window opening / closing mechanism 14 from being opened carelessly. .

As described in detail above, in this embodiment, when the window opening / closing mechanism 24 receives an operation load of a predetermined value or more during the closing operation of the window opening / closing mechanism 24, the window glass is temporarily set in the medium opening degree region. After the window glass 18 is moved in the opening direction by a predetermined amount and then moved in the closing direction again, the body or the body is moved between the window glass 18 and the window opening 22 by moving the window glass 18 in the opening direction by a predetermined amount. It is possible to prevent foreign matter such as clothes from being caught, thereby ensuring safety, and moving the window glass 18 again by a predetermined amount in the opening direction.
Is moved in the closing direction, after releasing the entrapment, the closing operation of the window glass 18 originally intended by the window operator is automatically performed, and in accordance with the intention of the window operator, the window operator again operates. The complexity of the operation of having to perform the window closing operation can be eliminated. Therefore, according to the present invention, it is possible to perform both of the release of the foreign object and the window closing operation that matches the intention of the window operator.

Further, in this embodiment, when the window glass 18 rises up to the small opening region, the closing operation is continued even when the window opening / closing mechanism 14 receives an operation load equal to or more than the predetermined value. Therefore, it is possible to prevent the window opening / closing mechanism 14 from being opened carelessly. In this case, in the small opening area, even if foreign matter is caught, the reversing operation of the window opening / closing mechanism 14 is not performed.
Is actually raised, it is easy to detect the possibility of foreign matter being pinched before reaching the small opening area, and to avoid this, so that safety is not impaired.

Further, in the present embodiment, when the window glass 18 stopped in the small opening area is raised, the window glass 18 is once lowered to the outside of the small opening area and then raised. Therefore, it is easy to detect the possibility of foreign matter being pinched while the window glass 18 descends to the outside of the small opening area, and to easily avoid this. Therefore, the window opening 2 that defines the small opening area
In setting the predetermined opening degree of 2, the safety is not impaired even if the predetermined opening degree is set to a relatively large opening degree, and the predetermined opening degree is set before the operation load of the window opening / closing mechanism 14 becomes excessive. A relatively large opening can be set.

Therefore, according to the present embodiment, it is possible to prevent the inadvertent opening operation of the window opening / closing mechanism 14 while preventing the occurrence of pinching of foreign matter.
