Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power window control device for controlling a power window that opens and closes a glass window provided in a side door of an automobile.

[Conventional technology]

In recent years, electric power windows that control the opening and closing of window glass by operating a switch have become popular, and there is an increasing demand for converting conventional manual types to electric types. This modification involved installing and wiring a motor for opening and closing the window glass, and also installing a switch on the door to control the opening and closing of the glass.

[Problem that the invention seeks to solve]

However, in order to control the rotational direction of the motor, a total of five wires (power supply wiring and control wiring) are required, and these wires are too thick to be accommodated in the existing door, so they are left exposed and strung around the inside of the car. It was in bad shape. For this reason, it is conceivable to connect only the power supply wiring to the motor provided in the door, and to centralize control of the rotational direction by providing a control section approximately in the center of the vehicle. However, in order to open and close the left and right windows of the front and rear doors individually, eight switches are required, but it is not only difficult to install this many switches in a small car interior, but also The disadvantage is that if there are many, the operation becomes complicated.

[Means for solving problems]

In order to solve these drawbacks, this invention
It consists of a receiver that is fixed inside the car and a receiver that is removably installed inside the car.The windows are controlled to open and close based on the signals sent from the transmitter, and can be switched between when the transmitter is installed and when the transmitter is not installed. The window that is to be opened and closed can be selected when the device is installed.

[Effect]

Control is performed wirelessly.

The motor 38 is a motor for opening and closing the window glass of the front right door. Further, the decoder 24 sends a detection signal of level "1" to the terminal 24a when the signal supplied from the detection circuit 23 indicates that the window glass of the left door has lowered, and when it indicates that the window glass of the left door has risen, the decoder 24 sends a detection signal to the terminal 24a.
A detection signal of "1" level is sent to terminal 24c when the window glass of the right door is lowered, and a detection signal of "1" level is sent to the terminal 24d when the window glass of the right door is rising. It is designed to send out a detection signal of "1" level.

FIG. 3 is a perspective view of a receiver attached to a dash board or the like. In the figure, buttons 15A,
Reference numeral 15B is for pressing switches 15a and 15b, which will be described later, and is housed in a recess that is lower than the surrounding area, so that it is normally not touched accidentally.
40 is an infrared filter, and 41 is a mounting bracket.

FIG. 4 shows a holder H attached to a rear console or the like on the left side of the driver's seat, and a transmitter T accommodated in this holder H. The transmitter T has a fixing groove 50 on the side surface in the longitudinal direction and a positioning groove 51 in the thickness direction, and when it is attached to the holder H with the infrared filter 4a in front, the groove engages with the holder H. The groove 51 engages with the positioning projection 53 and is fixed.

FIG. 5 is a cross-sectional view of the holder H, in which a magnet 54 is provided. Figure 6 shows the transmitter T
FIG. 7 is a cross-sectional view of FIG.
A reed switch 3e is provided at a position corresponding to 4.

The operation of the device configured in this way is as follows. When the ignition switch of the automobile is turned on, power is supplied to the terminal IG shown in FIG. 2, and the decoder 24 is reset for a predetermined period of time. This resets the decoder 24 to its initial state and prevents malfunction when the power is turned on. When the transmitter T is attached to the holder H, the reed switch 3e of the transmitter T is connected to the magnet 5 of the holder H.
It is turned on by 4. In this state, switch 3 of transmitter T is pressed to lower the window glass of the left door.
When a is pressed, a code signal corresponding to the on state of the reed switch 3e and the function of this switch is sent from the terminal 2a of the transmitter 2. Then, in response to this code signal, infrared rays are sent out from the light emitting diode 4, and this infrared ray is received by the photodiode 21 of the receiver R and converted into an electrical signal.

The electrical signal generated by the photodiode 21 is amplified by an amplifier circuit 22, detected by a detection circuit 23, and supplied to a decoder 24. The signal sent at this time is a signal to open the window glass of the left door, and is also a signal when the reed switch 3e is on, so the decoder 24 outputs a signal to the terminals 24a and 24.
A “1” level signal is sent from e. As a result, the signal sent from terminal 24e turns on transistor 11, drives relay 10, and switches contacts 10a-10d of relay 10 to the state and reaction direction shown in FIG. On the other hand, the signal sent from the terminal 24a is sent to the relay 31 via the inverter 26d.
The motor 37 rotates and the front left door window is opened.

Next, when the switch 3b of the transmitter T is pressed to close the window glass of the front left door, a detection signal is sent from the terminal 24b of the decoder 24, and the relay 32
is driven, the motor 37 is reversed, and the front left door window is closed. Similarly, switch 3c of transmitter T
When the switch 3d is pressed, the relay 33 is driven to open the front right door window, and when the switch 3d is pressed, the relay 34 is driven to close the front right door window.

When the transmitter T is removed from the holder H, the reed switch 3e is turned off. If the switch of the transmitter T is operated in this state, the decoder 24 will not send out a "1" level signal from the terminal 24e, so the relay will be turned off. 10 does not work. For this reason, terminal 24
The signals output from a to 24d are relays 27 to 3.
0 and rotates the motor 35 or 36, the window glass opening/closing control of the rear door is performed.
At this time, when switch 15a or switch 15b is operated, relay 10 is turned on, and contact 10
a to 10d are controlled to positions opposite to those shown in the figure, and a signal from the operation of this switch is supplied to the output of the detection circuit 23 via the inverter 26a.
Since the output signal of the detection circuit 23 is blocked, the signal from the transmitter T is no longer accepted. Therefore, the opening/closing control of the front door windowpane by the driver operating the switch 15a or 15b takes priority over the control of the transmitter T. Then, the signal output via the inverter 26b or 26c is sent to the relay 33.
Alternatively, since the relay 34 is driven, only the front right door, that is, the window glass of the driver's seat, can be opened and closed regardless of the operation of the transmitter T.

The transmitter T is provided with a light emitting diode 5 for displaying transmission, which lights up when any one of the switches 3a to 3d is pressed.
Therefore, if the display on the transmission display light emitting diode 5 is monitored when the switch is pressed, it can be determined whether the transmitter T is operating normally.

In such a device, when the battery of the transmitter is exhausted, the transmission output decreases, but in this case, it is sufficient to move the transmitter closer to the receiver. To do this, the transmitter must be removed from the holder, but in this state the opening and closing of the front window glass cannot be controlled. Even in such a case, the reed switch 3e may be replaced by a slide switch in order to control the opening and closing of the front window glass.

If the switch on the transmitter T is released while the window glass is being raised or lowered, infrared rays will no longer be transmitted, and the relays 27 to 34 that were operating will return to their original state, resulting in the state shown in FIG. This short-circuits the operating motor, causing it to be controlled and immediately stop. In addition, since the receiver will not operate unless the ignition switch is turned on, the window will not open even if it is pranked with a transmitter of the same type, reducing the risk of theft and increasing safety by preventing others from tampering with the receiver. can also be secured.

FIG. 8 is a circuit diagram showing another embodiment, in which a reed switch 3e is connected in parallel with a rebound type push button switch. It can be used without paying attention to the current location.

By locating the operation unit for opening and closing the window glass near the center of the vehicle, children will not be able to operate the switch carelessly, and there will be no risk of them getting caught in the window glass. Both can control the opening and closing of window glass. Additionally, conventionally, when modifying a power window, a total of three wires were required: the motor power supply wire and the control wire, and these wires needed to have a large diameter because they needed to carry a large current. Therefore, it was not easy to accommodate the motor inside the door, but according to the present invention, the wiring to the door only needs to be the power supply wiring for the motor, so it becomes easy to accommodate this wiring inside the door.

The transmitter T can be easily removed, and since the signal is transmitted using infrared rays, for example, if a sensor that detects infrared rays is installed in the garage, the driver can open the garage door while remaining in the car. It can also be used for opening purposes.

〔Effect of the invention〕

As explained above, in this invention, the transmitter is installed in a removable manner near the center of the vehicle interior, so there is no need to open or close the window glass carelessly, thereby reducing the risk of opening or closing the window glass. The window glass can be opened and closed from either the front or the rear with a small number of switches, which is convenient.
