JPS58185353A - Automatic selective actuator of automobile wiper - Google Patents

Abstract

PURPOSE:To reduce electric power consumption and eliminate the troublesome during driving, by providing an intermittence priority switch to automatically select a mode of wiper acturation. CONSTITUTION:If an intermittence priority switch D is placed in an ON-condition, low or high speed operation as in an indicator switch B is performed during running of an automobile, if the automobile stops running by a red signal, traffic jam, etc., a sensor E simultaneously detects this stop condition, and an electric circuit C1 performing intermittent operation through the switch D is closed while an electric circuit C2 or C3 performing low or high speed operation is opened, then a wiper A is automatically selected to intermittent operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a configuration that automatically switches the operating mode of an automobile wiper depending on whether the automobile is running or stopped.

That is, according to the present invention, when the driver selects the desired operation mode of the wiper A from intermittent, low speed, or high speed and operates the instruction switch B, any desired wiper operation can be obtained accordingly. Configured electric circuit 01. C
1,0! This electric circuit CI, 01! ,03
In connection with this, an intermittent operation priority switch D and a sensor IB that detects whether the vehicle is running or stopped are provided, and when the wiper A is operating at low or high speed and the intermittent operation priority switch D is ON, the vehicle is While the vehicle is running, it operates according to the instructions of the instruction switch B, and when the vehicle stops running, the sensor E detects this and closes the electric circuit 01 via the intermittent priority switch, causing the wiper A to switch.
is shifted to intermittent operation, and this state is maintained while the car is stopped, and when the car starts running, the sensor E switches the electric circuit C2 or C again as instructed by the indicator switch B. , the wiper A can be switched to low or high speed operation in the case N, when the wheel rotation has stopped, when the handbrake is used, when the engine rotation is in an idling state, etc. It works to close the electric circuit Cl, and in other cases closes the electric circuit at, 03 for low-speed or high-speed operation.

To explain the operating state of one embodiment of the present invention configured in this way, the operation instruction switch B of the wiper A and the intermittent priority switch D have a relationship as shown in FIG.
When the operating speed indication switch B of the wiper A is set to low or high speed, when the intermittent priority switch D is turned off, the wiper A will operate at the operating speed of the indication switch B while the car is running.
It can operate as expected.

In this case, when the intermittent priority switch D is turned on, the low or high speed operation is performed as indicated by the instruction switch B while the car is running, but as soon as the car stops running due to a red light, traffic jam, etc. The wiper A is automatically switched to intermittent operation by sensing and via the intermittent priority switch D, closing the electric circuit C1 for intermittent operation and opening the electric circuit C2 or C3 for low speed or high speed operation. Here, when the car starts moving again, the sensor E activates the wiper A at low speed or high speed in the electric circuit C2 or C3.
is closed and the electric circuit C1 for intermittent operation is opened, so that the wiper A is automatically switched to low speed or high speed operation according to the indication switch B.

Therefore, according to the present invention, the wipers operate at low speeds and high speeds unless a special instruction is given during driving when normal operation of the wipers is required, and there is no problem when driving in rainy weather.
The wipers operate intermittently when the vehicle is stopped and the vehicle is not needed, reducing electricity consumption.In addition, the wiper operation mode can be automatically switched, saving the driver the trouble of switching. This has the effect of reducing the occurrence of traffic accidents because the user can concentrate on driving the car without any discomfort or discomfort even when driving in the rain.

As an example of the sensor E, as shown in FIG. 8, when the intermittent priority switch p is ON, the speedometer 4
At the position where the pointer indicates zero, the electric circuit 5 is closed and the relay switch 6 is operated to open the low-speed operation switch 2 and the high-speed operation switch 3 and close the intermittent operation switch 1.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing the operating state of an embodiment of the present invention. FIG. 2 is a system diagram showing one embodiment of the present invention. Third
The figure shows an example of an electric circuit for implementing the present invention. In the figure, A is a wiper, and B is an instruction switch, which is comprised of switches B for stop, 1 for intermittent operation, 2 for low-speed operation, and 3 for high-speed operation. C1, C2, and C5 are electrical circuits for intermittent operation, low-speed operation, and high-speed operation, respectively. D is an intermittent priority switch, E is a sensor, and F is 12V1! is the source, g is the motor rotating cam, h is the brush, and 1 is the wiper stop electric circuit.

Claims (1)

[Claims] In a configuration in which the operating speed (low speed, high speed operation) or operation timing (intermittent operation) of the automobile wiper can be selected by an instruction switch, an intermittent priority switch and a sensor that detects whether the automobile is running or stopping are combined with the above structure. However, the wiper operation is automatically switched to intermittent operation by the function of the intermittent priority switch, which operates the wipers at the speed selected by the indicator switch, and if the car is running, the wipers operate at the speed selected by the indicator switch. When the wiper is operated and the intermittent priority switch is turned off, the wiper is operated according to the instruction switch regardless of the operation of the sensor accompanying the running and stopping of the automobile. An automatic switching device for automobile wipers.
