Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power window system for an automobile that raises and lowers an automobile window using a motor.

[Conventional technology]

Conventional general power window systems are shown in Figures 3 and 4.
As shown in the figure, there are three main switches 5 on the driver's side door to turn up and down the windows of each other door.
A one-touch switch 4 for raising and lowering the driver's side door window, and a lock switch 6 for locking the switch 5 are provided. One-touch switch 4 will open the window only when you are scratching.
There are provided a manual switch 4a that turns down the windshield, and an auto switch 4b that, when operated in one position, performs an amplifier-down operation of the window until it is fully open or fully closed. Further, the lock switch 6 is for locking the main switch 5 so that it cannot be scratched. On the other hand, each door other than the driver's door has a power window switch (hereinafter abbreviated as P/W switch) 3 for wind up/down.
is provided.

The power window system including each switch 3 to 6 is the third
The configuration is shown in the figure.

In FIG. 3, a battery V is supplied via an ignition switch 1 to a motor control circuit 2 for controlling a motor 7 on the driver's seat side, and is also supplied via a circuit breaker 9 to a timer relay circuit 10. A time control circuit 12 is connected to the timer relay circuit 10, and its output is supplied to the motor control circuit 2 and the main switch 5. The output of main switch 5 is each P
/W switch 3, and its output is supplied to the amplifier/down motor 8 for all door windows except the driver's seat.

In the motor control circuit 2, each terminal of the motor 7 is connected to a relay RLI.
, RL, are connected to the movable contacts. This relay RL
, RL, are commonly connected, and one common contact is supplied to the number detection timer 11. The other common contact is connected to the manual switch 4a through the excitation windings of relays RL, , Rt, . connected in parallel. That is, relay RL is for down and RL2 is for amplifier. The number detection timer 11 is supplied with power from a battery V via an ignition switch 1, and is connected to an auto switch 4b.

A lock switch 6 is connected to the main switch 5, and its output is supplied to the P/W switch 3.

Further, in the timer relay circuit 10, the contacts of the relay RL and the excitation winding of the relay RL are connected in series to the battery (2). The contacts (reed switch) of the timer control circuit 12 and the relay RL 4 are connected in series, and the relay RL is connected between the battery ■ and the time control circuit 12.

The excitation winding of is connected. This time control circuit 12 is
As shown in FIG. 5, the operating time of each automotive unit including a timer relay circuit 10, such as wipers, various lamps, ignition, and a clock, is controlled.

In the above configuration, when the ignition switch 1 is turned on, the output of the time control circuit 12 causes the relay RL,
is driven, and current flows from battery V to relay RLa. This connects battery V to the common connection point of one of relays RL+ and RLz of motor control circuit 2. Therefore, by switching the manual switch 4a, the relay RL or RL2 is energized, and currents flow in the motor 7 in the opposite directions of the window up and down directions. In addition, since the battery V is also supplied to the main switch 5, it is possible to operate the amplifier and down of the driver's seat and other windows, and also to raise and lower the corresponding windows by operating each P/W switch 3. becomes possible.

If the auto switch 4b is turned on, the number detection timer 11 detects this and continues to supply current to the motor 7 even if the manual switch 4a is released. Further, when the lock switch 6 is turned on, the state of the main switch 5 is locked.

Here, when the ignition switch 1 is turned from on to off, the output of the time control circuit 12 remains constant for a predetermined period of time (for example, 30
second) becomes low level, and current flows through the excitation winding of relay RL3, and relay RL3. Power is supplied to the motor control circuit 2 and main switch 5 via RL. During this predetermined time, ignition switch 1
Even if it is off, the window can be raised and lowered as described above.

[Problem that the invention seeks to solve]

In such a conventional configuration, when the car is parked, the doors are locked, and an attempt is made to leave the car, the windows are down and the predetermined period of time has elapsed since the ignition switch was turned off. If so, in order to raise the window, you must unlock the door again, enter the room, turn on the ignition switch 1, and then operate the up/down switches 4 and 5.

[Means for solving problems]

The present invention has been made in view of the above-mentioned conventional problems, and its means includes a motor for raising and lowering an automobile window, a detection means for detecting a key lock state of a door, and a means operated by the detection means. The device includes a timer means and a switch means that is switched by the output of the timer means.

[Action of the invention]

In the above means, the switch means operates so that if the key is in the locked state, a wind-up current is continuously supplied to the motor, and if the key is in the unlocked state, the amplifier current is supplied for a predetermined period of time by the timer means. It is something to do.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the same parts as in FIGS. 3 and 4 are denoted by the same reference numerals.

In FIG. 1, a timer circuit 13 is connected to the battery V,
A key-up switch 14 and a key-lock detection switch 15 are connected in series for drive control. The timer circuit 13 includes a transistor Q, a resistor RI'R4, and a capacitor C connected between its base and collector, and the collector outputs are connected to relays RL, ~RL, respectively. , and RL are each connected to the battery V, one fixed contact is opened, and the other fixed contact is connected to one end of the driver's seat window motor 7 and the other window motor 8, respectively. The movable contacts of relays RL7 and RL are each connected to one end of each motor 7.8 (one fixed contact of relays RLI, RL&), each one of the fixed contacts is open, and the other fixed contact is used for motor control.

The movable contact of the P/W switch 3 is connected to the motor 8 in the connection line.

Further, as shown in FIG. 2, the key-up switch 14 is provided on the door on the driver's seat side together with the warning switch 5 and the like.

In such a configuration, if the key-up switch 14 is off, the transistor Q of the timer circuit 13 is off, and the relays RLs to RL are not excited. Therefore, each contact is in the state shown in FIG. 1, and performs the same configuration and operation as in FIG. 3. On the other hand, when the key amplifier switch 14 is turned on and the door is locked with the door key cylinder (door lock state), the detection switch 15 is turned on. Therefore, the transistor Q of the timer circuit 13 is turned on, and the relay RL s
~RL s is energized and its contacts are switched respectively.

Therefore, power is supplied to the motor 7 from the battery V through the relay RL, and the power flows through the contacts of the relay RL, so that the window is raised (at this time, the manual switch 4a is set to either the up or down position. (not switched).

Furthermore, even if the key lock detection switch 15 is turned off (unlocked state B), the transistor Q remains on for a predetermined period of time when the discharge of the capacitor C ends, so the relays RL, ~R
Each contact point of L maintains the above-mentioned locked position,
The window is up.

On the other hand, the motors 7 other than the driver's seat also operate in the same manner as described above to wind up when the door is locked, and wind up for a predetermined time when the door is unlocked.

〔Effect of the invention〕

As described above, according to the present invention, when the car door is locked and the car is parked, even if the window is down, there is no need to operate the window up/down switch inside the car.
Even if the ignition key is turned off, it can be turned up by locking the door key.
