Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power window regulator in which a speed-changeable drive motor is used to open and close the window glass by changing the ascending / descending speed of the window glass in two stages, low speed and high speed.

[0002]

[Prior art]

 An example of a conventional power window regulator is disclosed in Japanese Utility Model Laid-Open No. 2-77287. That is, the motor is configured so that the speed can be switched in two stages, and the changeover switch is operated to switch the operating speed between the opening operation and the closing operation of the window glass.

[0003]

[Problems to be solved by the device]

 However, with such a conventional power window regulator, for example, when finely adjusting the raising / lowering position of the window glass due to the need for ventilation in the vehicle in rainy weather, the user bothers to switch the changeover switch to the one with a lower raising / lowering speed. There was a problem that it had to be selected and was not easy to use. If you standardize the motor with a high lifting speed, fine adjustment of the lifting position does not go as you expected, and the lifting operation is repeated, and it is not convenient, while unifying the motor with a low lifting speed. However, it takes a long time to change the raising / lowering position drastically, and there is a problem that it is not easy to use.

The present invention has been made in view of such a conventional problem, and by providing a timer circuit and driving the drive motor at a low speed for the first fixed time, the fine adjustment of the door glass can be easily performed. In addition, the purpose is to provide a power window regulator that is easy to use.

[Means for Solving the Problems]

 The gist of the present invention for achieving such an object is to open / close the window glass (20) by changing the ascending / descending speed of the window glass (20) in two stages, low speed and high speed, by a speed-switchable drive motor (40). In the power window regulator, the relay contact (S3) that switches from one of the contact on the high speed side and the contact on the low speed side to the other depending on the change of the energization state whether or not to energize the coil (R3) of the relay. , Has a time delay contact (Tr) connected to the relay coil (R3), and the open / closed state of the time delay contact (Tr) changes after a certain period of time has elapsed since the elevating switch (SW) was operated. The energization state of the coil (R3) changes, the contact (S3) of the relay switches from the contact on the low speed side to the contact on the high speed side, and the ascending / descending speed of the window glass (20) is switched from the low speed to the restraint. It exists in a power window regulator characterized by having a timer circuit adapted to do so.

[0006]

[Action]

 When the elevating switch (SW) is operated, for example, the timer circuit is turned on and the coil (R3) of the relay is energized. As a result, the contact (S3) of the relay is switched from the contact on the high speed side to the contact on the low speed side, the speed of the drive motor is switched, the window glass (20) becomes low speed, and the opening and closing operation is performed to easily move up and down. The position can be finely adjusted. After the elevating switch (SW) is operated and a certain time has passed, for example, the timer circuit is turned off and the coil (R3) of the relay is de-energized. If the relay coil (R3) is not energized, the relay contact (S3) switches from the low speed side contact to the high speed side contact, the speed of the drive motor (40) is switched, and the window glass (20) is removed. It can be opened and closed at high speed, and the window glass (20) can be raised and lowered significantly in a short time.

A drive motor 40 is mounted on the base member 33, and a pinion 42, to which the rotational force of the drive motor 40 is transmitted via a deceleration mechanism 41, meshes with a tooth for pinion engagement of the sector gear 35. As shown in FIG. 3, the drive motor 40 is configured such that it can rotate in the normal and reverse directions and the speed can be switched, and the commutator pieces are continuously arranged on the circumference. The brushes on the side are arranged in contact with the commutator pieces.

As shown in FIG. 1, the window glass drive circuit includes an elevating switch SW for switching the forward / reverse rotation of the drive motor 40 to move the window glass 20 up and down. And contact points of. The switch piece of is connected to the + electrode of the battery.
