Description of drawings

Fig. 1 is a schematic diagram of a module of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. the

As shown in Figure 1, the utility model designs an automatic wiper device, including a wiper brush, a linkage rod, a wiper motor, an infrared rain sensor and a power supply, wherein the infrared rain sensor is arranged on the windshield On the inner side, the wiper motor is connected to the wiper brush through a linkage rod, and also includes a wiper control device and a wiper position sensor connected thereto, wherein the power supply device is connected to the wiper control device , and supply power to other devices through the wiper control device, the wiper control device is respectively connected with the infrared rain sensor and the wiper motor, and the wiper position sensor is set on the wiper motor, which can realize the automatic operation of the wiper And the automatic adjustment of the running speed; the electronic control method is used to realize the automatic return operation of the wiper brush.

As a preferred technical solution of the utility model: it also includes an engine speed sensor connected with the wiper control equipment to monitor the engine speed in real time, so that the automatic wiper device designed by the utility model realizes In the case of a car, the automatic return operation of the wiper brush is also realized.

As a preferred technical solution of the utility model: the power supply device is a storage battery.

As a preferred technical solution of the utility model: the wiper control device is a microprocessor.

The automatic wiper device designed by the utility model is connected to the power supply equipment of the automatic wiper device during the specific use process to supply power for the whole set of automatic wiper device, and the whole set of automatic wiper device automatically works according to the following working mode:

The engine speed sensor monitors the speed of the engine in real time, and sends the monitoring result signal to the wiper control device; the infrared rain sensor monitors the rainfall situation in real time through infrared, including whether there is rain and the size of the rainfall, and will monitor The resulting signal is sent to the wiper control device; the wiper position sensor monitors the position of the wiper in real time, monitors whether the wiper is at the lowest position, and sends the monitoring result signal to the wiper control device; the wiper The control device automatically operates the wiper brushes through the wiper motor according to the monitoring result signals of the engine speed sensor, the infrared rain sensor and the wiper position sensor.

Situation 1. When the engine is working, that is, the engine speed sensor detects that the engine speed is not 0; the infrared rain sensor detects rain information and rainfall information; no matter whether the wiper position sensor detects that the wiper blade is at the lowest position ; At this time, the wiper control device controls the wiper motor to work, and adjusts the working speed of the wiper motor according to the amount of rain.

Situation 2. When the engine is working, that is, the engine speed sensor detects that the engine speed is not 0; the infrared rain sensor detects no rain information; the wiper position sensor detects that the wiper blade is at the lowest position; at this time, The wiper control device controls the wiper motor to stop working, so the wiper motor does not work.

Situation 3. When the engine is working, that is, the engine speed sensor detects that the engine speed is not 0; the infrared rain sensor detects no rain information; the wiper position sensor detects that the wiper blade is not at the lowest position; at this time , the wiper control device controls the wiper motor to work until situation 2 is reached, the wiper control device controls the wiper motor to stop working. Because the wiper control device adopts an electronic control method to control the wiper motor, it can control the wiper motor to stop quickly, avoiding the inertia effect and causing failure.

Situation 4. When the engine is not working, that is, the engine speed sensor detects that the engine speed is 0; no matter whether the infrared rain sensor detects rain information; the wiper position sensor detects that the wiper blade is at the lowest position; at this time , the wiper control device controls the wiper motor to stop working, then the wiper motor does not work.

Situation 5. When the engine is not working, that is, the engine speed sensor detects that the engine speed is 0; no matter whether the infrared rain sensor detects rain information; the wiper position sensor detects that the wiper blade is not at the lowest position; , the wiper control device controls the wiper motor to work until situation 4 is reached, the wiper control device controls the wiper motor to stop working.

The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned embodiments. Make various changes below.
