Description

[Detailed Description of the Invention] This invention relates to a drive control device for a power window regulator for a door without a door.

In general, the operation of a power window regulator can be controlled centrally from the driver's seat, while passengers in the front passenger seat and rear seats can also operate the drive switch installed on each door. It's getting under control. By the way, if the window glass of the door that passengers are trying to get on and off from remains fully closed, as shown in Figure 1, the opening dimension _L1 for getting on and off is narrow, making it easy for the head and shoulders to hit the window glass, making it difficult to get on and off the vehicle. . Therefore, it is desirable to lower the window glass when getting on and off and expand the opening size for getting on and off to L ₂ (<L ₁ ) to improve the ease of getting on and off. It is difficult to operate and is not practical if it is lowered.

In view of this situation, this invention lowers the window glass in conjunction with the opening of the door when getting on and off, and raises the window glass in conjunction with the closing of the door to the state before the door was opened, thereby improving the ease of getting on and off. An object of the present invention is to provide a drive control device for a power window regulator that is improved without deterioration.

As a configuration for achieving this purpose of this invention,
Basically, a switch that detects the opening and closing of the door is installed in parallel with the drive switch that drives the regulator indoors, and this switch automatically lowers and raises the window glass in conjunction with the opening and closing of the door. A drive control circuit is formed, and a memory device is interposed in this drive control circuit to memorize the position of the window glass before the door is opened, so that when the door is closed, the window glass automatically rises to the above-mentioned memorized position. It is something. As the storage device, in addition to a mechanical type having a memory plate, a magnetic type having a magnetic tape, etc. can be adopted.

The details of this invention will be explained below with reference to embodiments shown in the drawings.

Figure 2 is a block diagram showing the drive control circuit when this invention is applied to the left rear door, where A is the drive switch to operate the window regulator indoors, and B is the switch that detects the opening/closing of the door (hereinafter referred to as "drive switch"). C is a storage device, D is a motor control circuit, and E is a power window regulator motor (hereinafter referred to as a motor). Drive switch A independently drives motor E in forward or reverse rotation to open the window. The glass can be raised and lowered, and a motor E can be driven and controlled via a storage device C in conjunction with door opening/closing detected by a door switch B in parallel with this switch A. That is, the glass position when the door is closed is stored in the memory device C, and when the door is opened, the motor E is driven by the detection output of the door switch B to lower the window glass, and when getting on and off is completed and the door is closed, The motor is driven by the detection output of the door switch B, and the window glass is raised to the position stored in the storage device C.

FIG. 3 shows an example of the window glass lifting device according to the first embodiment, FIG. 4 shows an example of the structure of the storage device, and FIG. 5 shows an example of the drive control circuit of this device.

A door window glass 1 is set on a front guide rail 3 and a rear guide rail 4, and is positioned vertically by a lift arm 7 via a bracket 1b bonded to the door window glass 1 with an adhesive. The door window glass 1 and the bracket 1b may be joined by a method other than adhesive. The elevating arm 7 and the elevating gear 8 are attached to the base plate 14 by the elevating arm shaft 5 so as to be rotatable about the elevating arm shaft 5. A flange is provided on the end face of the lifting gear 8, against which the lifting arm 7 is constantly pressed. A limit switch 12 is attached to the elevating gear 8, so that when a force is applied in a direction to compress the elevating arm 7 and the elevating gear 8, the displacement can be detected.
The lifting gear 8 is connected to the gear of a window glass lifting motor 11 via an intermediate gear 10 attached to an intermediate gear shaft 6 fixed to a base plate 14. The limit switch 13 is fixed to the base plate 14 so as to detect the position when the lifting gear 8 rotates to the lower limit position of the door window. The door opening/closing detection switch 16 is connected to the door body 1.
7 and is connected to send a signal to relay 15 that turns the switch on when the door opens and turns it off when the door closes. Note that the door opening/closing detection switch 16 does not necessarily need to be attached to the door body 17 as long as it is located at a position where opening/closing of the door can be detected. The base plate 14, the front guide rail 3, and the rear guide rail 4 are each fixed to the door body 17, and their relative positions are determined.

FIG. 4 illustrates a mechanical door window glass position storage device. Code 18 to 26
These are the constituent parts of the storage device. Also, 27a,
27b is an operation switch for manual lifting/lowering. 1
Reference numeral 8 denotes a memory plate which is attached to the lifting arm shaft along with the lifting arm 7 and the lifting gear 8. The memory plate 18 also has a spring holder 25 fixed to the base plate 14 at one end.
It is held in such a way that it does not rotate naturally. The memory plate 18 has one end joined via a joining pin 20 to an iron core 21 that penetrates and is supported by a hole in a core holder 23 fixed to the memory plate 18 .
A memory clutch 19 supported through a hole penetrated is attached, and the tip of the memory clutch 19 is fitted into a slit 8a provided in the lifting gear 8. The portion of the memory clutch 19 fitted into the slit 8a is machined to have an elliptical cross section, and its major axis is larger than the slit 8a and its minor axis is smaller than the slit 8a. A memory clutch magnet 24 is also fixed to the memory plate 18, facing the open end of the iron core 21. A core return spring 22 is inserted between the joining pin side of the iron core 21 and the iron core holder 23, and constantly pushes the iron core 21 back to the side opposite to the memory clutch magnet 24. 27a,
27b is a switch for manually raising and lowering the door window glass 1, and is fixed to the door body 17. The limit switch 26 is for checking the original position of the door glass, and is fixed to the base plate 14 so as to be in a position where it is struck on the end face of the memory plate 18 when the memory plate 18 rotates to the upper limit position. When the iron core 21 is not attracted to the memory clutch magnet 24, the long axis of the memory clutch 19 is inclined counterclockwise from the slit 8a of the lifting gear, so that the connection between the memory plate 18 and the lifting gear 8 is broken. There is.

In the state shown in FIG. 3, the memory plate 18 is at the upper limit position, its end face is in a state where it has hit the limit switch 26, and the core 21 of the memory clutch 19 is pushed back by the core return spring 22 in the opposite direction to the memory clutch magnet 24. Therefore, it rotates to the left and is free from the slit 8a provided in the lifting gear 8. When the manual switches 27a and 27b are turned on in this state, the door window glass lifting motor 11 rotates, and the lifting gear 8 and lifting arm 7 rotate around the lifting arm shaft 5, but the memory plate 18 remains pressed by the spring holder 25. It doesn't move. Therefore, the manual switches 27a and 27b do not cause any trouble to the storage device. When the door is opened here, the door opening/closing detection switch 16 is turned on.
Coil 15a of relay 15 is energized and contact 15b
will be inherited. Here, when the door window glass 1 is not at the lower limit and the end face 8' of the lifting gear 8 is not hitting the limit switch 13, the door window glass lifting motor 11 rotates forward and the lifting gear 8 and lifting arm 7 rotates in the downward direction. At the same time, current also flows through the memory clutch magnet 24, and the memory clutch magnet 24 attracts the iron core 21. Then, the memory clutch 19 connected to the iron core by the joining pin 20 rotates clockwise, and the memory clutch 19 moves through the slit 8 provided in the lifting gear 8.
a, the memory plate 18 rotates together with the lifting gear 8 in the direction of lowering the door window glass. When the door window glass 1 reaches its lowering limit and the end face 8' of the lifting gear hits the limit switch 13, the door window glass lifting motor 11 stops. Next, when the door closes, door open/close detection switch 1
6 is disconnected, and the contact 15c of the relay 15 is turned on.
Then, a current flows to the reverse side of the door window glass lifting motor 11, the door window glass lifting motor 11 is reversed, and the lifting gear 8 is rotated to the door window glass raising side. At this time, current also flows through the memory clutch magnet 24 and the iron core 21.
The memory plate 18 and the elevating gear 8 are connected and rotated at the same time in the same way as when the door window glass is lowered. When the door window glass 1 rises to the position when the door is opened, the memory plate 18
hits the limit switch 26 to cut off the current to the door window lift motor 11, and the door window glass 1 stops at its original position. At the same time, the current in the memory clutch magnet 24 is also cut off, and the memory plate 18 and lifting gear 8 are released.

FIGS. 6 and 7 are diagrams illustrating a magnetic door window glass position storage device. Code 1~ in the figure
The parts up to 17 are the same as the door/window automatic lifting device shown in FIG. 3, and the parts 28 to 30 are the components of this storage device. 28 is fixed to the elevating gear 8 with magnetic tape or by a similar method. Reference numeral 29 denotes a magnetic tape reading device 30, which is a magnetic tape writing 30a and erasing 30b device, and is fixed to the base plate 14 so as to be at the a-end of the magnetic tape when the elevating gear 8 rotates to its upper limit.

Next, the operation of the magnetic door window glass position storage device will be explained with reference to FIG. magnetic tape 28
is attached to the elevating gear 8, and rotates around the elevating arm shaft 5 together with the elevating gear.
Manual switch 27a,
When inserting 27b and moving it up and down, use magnetic tape writing 3.
0a, the erasing device 30b operates, and the magnetic tape 28
It is magnetized by the rotation angle α of the elevating gear corresponding to the elevating and lowering of the door window glass 1. This state is shown in FIG.
is excited, the contact 15b turns on, the door window glass lifting motor 11 rotates forward, and the lifting gear 8
is rotated to the lower limit position of the door window glass as shown in FIG.
Thus, the magnetic tape 28 remains unmagnetized.
Next, when the door is closed, the door open/close detection switch 16
The contact C of the relay 15 is turned on, the door window glass lifting motor 11 is reversely rotated, and the lifting gear 8 and the magnetic tape 28 attached thereto are rotated in the upper limit direction. When the elevating gear 8 returns to the door glass position when the door is opened, the magnetic tape reader 2
9 reads the magnetized portion of the magnetic tape 28 and cuts off the current to the door window glass lifting motor 11. This causes the door window glass to return to its original position and stop.

As described above, according to this invention, when the door is opened to get on and off, the window glass automatically lowers, making it easier to get on and off.
When the door is closed, the window glass can be automatically raised to the state before the door is opened and stopped, and the effect is that the ease of getting on and off the vehicle can be improved without forcing the occupant to perform any special operations.

Additionally, if the window glass is left half-open for ventilation before the door is opened, the memory device will return it to its original position even after the door is closed, so you will have to open it half-open again. It is extremely practical and requires no complicated operations.
