Abstract

A raining sensor comprises a shell body, a shell cover, a pedestal arranged on the bottom of the shell body, a substrate arranged on the pedestal, a surrounding environment light sensor arranged on the substrate, a photodiode, a light sensor, and a light emitting diode. By adopting the raining sensor, the technical problem that during the driving process, certain safety hidden troubles influencing the driving safety of a driver can be caused by opening a water spray button and a wiper switch is solved. For the driver, the temporary manual control method of dealing with raindrops on a wind screen glass and activating an automatic water-wiping system when an automobile is started or during the driving process is no longer needed. By adopting the raining sensor, the raindrops on the wind screen glass can be identified, and a wiper on the wind screen glass can be automatically operated. The safety hidden troubles of opening the wiper during the driving process are eliminated, and the personal safety is ensured.

Description

Rain sensor

Technical field

The utility model relates to a kind of driver's driving safety and uses sensor, is specifically related to a kind of rain sensor.

Background technology

Automobile can run into the rainy day under steam unavoidably, falls on the windshield when rainwater, can block driver's sight line; Influence driver's driving; And traditional approach is to be sprayed water on controlling windshield through switch in the control car by the driver, and controls wiper and handle being attached to foreign material on glass, but the driver generally in the process of moving; Remove out spraying button and wiper switch again, driver's driving safety has been caused certain potential safety hazard.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of rain sensor.

A kind of rain sensor, this sensor comprises housing, cap is arranged at the pedestal of housing bottom, is arranged at the substrate on the pedestal, is arranged at the surrounding environment optical sensor on the substrate, photodiode, optical sensor, and light emitting diode.

Be bonded with substratum transparent on the above-mentioned cap.

Above-mentioned cap is perspective insulation shape cap.

The utlity model has following advantage:

Changed concerning the driver, handled the raindrop on the windshield, can only adopt interim manual control mode, needed behind automobile starting or in the process of going to activate and scrape water system automatically.Rain sensor can be discerned the water droplet on the windscreen, and can automatically handle the wiper on the windscreen.Eliminate the potential safety hazard of opening wiper when the driver drives and diverting one's attention, guaranteed personal safety.

Description of reference numerals:

Housing 1; Cap 2; Substratum transparent 3; Pedestal 4; Substrate 5; Surrounding environment optical sensor 6; Photodiode 7; Optical sensor 8; Light emitting diode 9, receiver 10, windshield 11, water droplet 12, sensor body 13.

Embodiment

Referring to shown in Figure 1, the rain sensor that the utility model provides comprises housing 1, cap 2; Be arranged at the pedestal 4 of housing bottom, be arranged at the substrate 5 on the pedestal 4, be arranged at the surrounding environment optical sensor 6 on the substrate 5; Photodiode 7, optical sensor 8, and light emitting diode 9; Be bonded with substratum transparent 3 on the said cap 2; Cap 2 is perspective insulation shape cap.

Referring to shown in Figure 2, light emitting diode 9 emission light, this light accumulate on the windscreen with certain angle and in the windscreen outer bounding surface total reflection of doing, arrive the receiver 10 of photodiode 7 again with same angle.If the outside surface of windscreen has water droplet 12, then most of light outwards reflects, the reception signal weaker on the receiver 10.A little less than signal, to a certain degree, also be that raindrop arrive to a certain degree by force, wiper is then connected automatically.

Referring to shown in Figure 3, this sensor body 13 on can being adhered to windshield 11, can also directly be installed in the room mirror, wide-angle ground detects rainfall outside window.

Claims

1. rain sensor, this sensor comprises housing, cap; It is characterized in that: also comprise the pedestal that is arranged at housing bottom, be arranged at the substrate on the pedestal, be arranged at the surrounding environment optical sensor on the substrate; Photodiode, optical sensor, and light emitting diode.

2. rain sensor according to claim 1 is characterized in that: be bonded with substratum transparent on the said cap.
