Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power window control device for an automobile door.

Conventional power windows > IJIJ control J/C For J/C, a changeover switch for controlling the power window motor is often installed in an interior assembly part such as a center console or door armrest, and this changeover switch By repeating this operation, the power window motor is rotated forward or reverse to raise or lower the windshield, and at the same time, the limit switch turns off at the upper and lower limits of the windshield, respectively, and the windshield is set at the upper limit. Alternatively, when the lower limit is reached, the motor drive circuit is opened to stop the windshield from rising or lowering.

However, with this conventional structure, there was a problem in that if a car was parked and the driver got out of the car with the windshield open, the driver would have to open the door again and operate the changeover switch.

The present invention takes into account the conventional situation, and even when the door is locked while the window glass is open, the driver can
The first object of the present invention is to provide a power window control device 1141 that can raise the windshield in a constant manner.

In order to achieve the above objective, the present invention uses a changeover switch to drive the power window motor to the ascending side and descending side of the windshield in +1tII system, and also to control the ascent limit and descending position of the windshield. The motor body -σ is controlled by the limit switches that turn off at 1〆r.
It has a configuration in which one circuit is opened and opened, and a change-over switch system 411 means is thin-filmed to sense the locked state of the door and move the front hL change-over switch to the windshield rising side.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the figure, ■ is a reversible power window motor that operates a window regulator mechanism (not shown), and 2 it is a changeover switch that drives and controls the power window motor 1 (not shown) to raise or lower the windshield, and can be manually operated. It consists of a first contact 3 that is connected to the terminal 3, and a second contact 4 that operates in conjunction with the first contact 3.

For example, in this embodiment, the changeover switch 2 is configured such that movable contacts 3a and 4a of the first contact 3 and second contact 4 are interlocked from the neutral position shown by chain lines to one fixed contact 3b and 4b, respectively.
When the movable contacts 3a and 4a are connected to the other fixed contacts 30 and 40, the electric pressure of the battery 5 is applied to the motor 1 to rotate the motor 1 in the normal direction so that the window glass is placed in the upper row. Motor 1 is reversed to close the window glass.

A limit switch 6 is provided between one fixed contact 4b of the second contact 4 and one terminal 1a of the motor 1, and the limit switch 6 is turned off when the window glass reaches the raised position. 4c and the other terminal tb of the motor 1 is provided with a limit switch 7 that is turned off when the windshield reaches the lower limit position, and when the power window motor 1 is driven, the windshield is moved to the upper limit position or lower limit position. When the position is reached, the limit switch 6 or 7 is turned off to open the pivot circuit of the motor 1 and stop the windshield from rising or falling.

Then, the front d (battery 5. selector switch 2. motor 1. limit switch 6. A switch control means 8 is provided.

This control means 8 includes a steering lock switch 9 (not shown) that is turned on when the ignition key is removed, a timer switch 9 (not shown) that is turned on when the ignition key is removed, a timer that is turned off after being turned on for a set time 9, a door lock switch 11 (not shown) that is turned on when the door is locked, and these switches. When the switch 9゜1J and the timer IO are turned on, a negative pressure is applied to the battery 5, and the excitation coil 12 energizes the moving contact 3a to close the first contact 3 of the changeover switch 2 to the one fixed contact 3b. It consists of a series circuit with.

Next, the operation of the above embodiment apparatus will be described in detail.

The raising and lowering operation of the windshield trace is performed by manual operation of the on/off switch 2 as in the conventional case, and the movable contact 3a of the first contact 3 is connected to the fixed contact 3b on the windshield rising side or the windshield lowering side 1 [ 41], when the fixed contact 3cK of the second contact 4 is turned on, the movable contact 4a of the second contact 4 changes to -iJ! , and the identification contact 4b or 4C is connected to the power window motor l.
The father rotates the windshield in the forward direction and reverses it to raise or lower the windshield. When the windshield is fully opened or fully opened, the limit switch 6 or 7 is turned off and the motor ``:11.'' is turned off.
It is regulated by the dynamic circuit being opened.

Next, I pulled out the ignition key and locked the door without noticing that the window glass was open. On the other hand, when the ignition key is removed, the steering lock switch 9 is turned on, and when the door is locked, the door lock switch 1 is turned on. This is the setting time of timer + 1J excitation coil 1
The voltage of the battery 5 is applied to 2, the movable contact 3a of the first contact 3 is energized, and the movable contact 3a of the 161 constant contact 3b is turned on. The movable contact 4a is connected to one of the fixed contacts 4b, and the motor u (< dd+ circuit on the windshield rising side is closed. As a result, the windshield automatically rises, and at its rising limit 1f6', the IJ When the switch 6 is turned off, this motor opens the path and stops the windshield from rising.Then, after the set time of the timer IO, the timer IO is turned off and the control hand is turned off. The series circuit of general 8 is Kaisei t11, coil [2 crab rl!
A is returned to the neutral position, and in conjunction with this, the opening contact 4a of the second contact 4 is also returned to the neutral position.

The above means that the window glass is fully open at 1ψ.9 If the door is already locked, one limit switch 6 is off because the window glass is fully open.
The other limit switch 7 is in the on state. Therefore,
By removing the ignition key, getting out of the car, and locking the doors, switch the steering lock switch 9. Door lock switch 11 turns on IlυI, I+if no 1'

In the above embodiment, the changeover switch is operated by sensing the locked state of both the steering wheel and the door, but the switch may be controlled by sensing only the locked state of the door.

As described above, according to the present invention, even if a person gets out of the car without noticing that the window glasses are open and then opens the door, the twin windows can be raised automatically. Therefore, there is no need to open the door each time to return to the room and operate a switch, and it also has a great practical effect in that it prevents unnecessary accidents caused by forgetting to close the window glass. have,
