Problems solved by technology

Some high-end cars have a heating device on the rearview mirror. The electric heating wire on the lens makes the rain and fog heat up and evaporate until it is eliminated; because this kind of heating device has a large power, it can only be used for a short time, otherwise, it is easy to cause damage to the lens and related damage. Damaged electrical components
[0004] In the process of realizing the present invention, the inventor found that there are at least defects such as poor use effect and large safety hazards in the prior art

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] According to an embodiment of the present invention, a control circuit for removing rainwater from a car rearview mirror by using ultrasonic waves is provided. Such as figure 1 As shown, this embodiment includes a battery 3 , an ignition switch 1 , a wiper control switch 2 , a normally open wiper motor control relay 4 , a wiper motor 5 , a normally open ultrasonic generator control relay 6 and an ultrasonic generator 7 . Here, the sonotrode 7 is arranged close to the car rearview mirror (that is, the sonotrode 7 is arranged near the car rearview mirror).

[0018] Wherein, the negative pole of the battery 3 is grounded; the positive pole of the battery 3 is g...

Abstract

The invention discloses a control circuit for removing rainwater of an automobile rearview mirror by using ultrasonic wave. The control circuit comprises a storage battery, an ignition switch, a wiper control switch, a normally-open wiper motor control relay, a wiper motor, a normally-open ultrasonic wave generator control relay and an ultrasonic wave generator, wherein the negative electrode of the storage battery is grounded; the positive electrode of the storage battery is grounded after passing through the ignition switch, the wiper control switch and an electromagnetic coil of the normally-open wiper motor control relay, is grounded after passing through a control contact of the normally-open wiper motor control relay and the wiper motor, and is grounded after passing through the normally-open ultrasonic wave generator control relay and the ultrasonic wave generator; and the electromagnetic coil of the normally-open ultrasonic wave generator control relay is connected in parallel with the electromagnetic coil of the normally-open wiper motor control relay. Through the control circuit for removing the rainwater of the automobile rearview mirror by using the ultrasonic wave, the defects such as poor application effect, high potential safety hazard and the like in the prior art can be overcome to realize a good application effect and low potential safety hazard.

Description

technical field [0001] The invention relates to an automobile circuit, in particular to a control circuit for removing rainwater from an automobile rearview mirror by using ultrasonic waves. Background technique [0002] At present, car rearview mirrors are used by drivers to monitor the conditions of pedestrians or vehicles on both sides of the car, which is especially important for driving safety, especially when turning, reversing or changing lanes. In rainy weather, car rearview mirrors are easily stained with rain, which will seriously affect the driver's sight and easily lead to traffic accidents. [0003] Generally, there is no wiper device for removing rainwater on the car rearview mirror. Some high-end cars have a heating device on the rearview mirror. The electric heating wire on the lens makes the rain and fog heat up and evaporate until it is eliminated; because this kind of heating device has a large power, it can only be used for a short time, otherwise, it is...
