For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: a kind of control circuit that utilizes super sonic to remove the automobile rearview mirror rainwater; Comprise storage battery, ignition lock, wiper control switch, often open rain shaving electrical machine control relay, rain shaving electrical machine, often drive ultrasonic generator control relay and ultrasonic generator, wherein:
The negative earth of said storage battery; The positive pole of storage battery; Ground connection through ignition lock, wiper control switch and after often opening the magnet coil of rain shaving electrical machine control relay successively; Often open ground connection behind control contact and the rain shaving electrical machine of rain shaving electrical machine control relay successively, and often open ground connection behind ultrasonic generator control relay and the ultrasonic generator successively; It is parallelly connected with the magnet coil of often driving the rain shaving electrical machine control relay often to open the magnet coil of ultrasonic generator control relay.
Further, said ultrasonic generator is near the automobile rearview mirror setting.
The super sonic that utilizes of various embodiments of the present invention is removed the control circuit of automobile rearview mirror rainwater since comprise storage battery, ignition lock, wiper control switch, often open rain shaving electrical machine control relay, rain shaving electrical machine, often drive ultrasonic generator control relay and ultrasonic generator; Can utilize the hypracoustic vibration to remove the rainwater on the automobile rearview mirror, to ensure the rainy day traffic safety; Thereby can overcome the not good and big defective of potential safety hazard of result of use in the prior art, with the advantage that realizes that result of use is good and potential safety hazard is little.
Other features and advantages of the present invention will be set forth in specification sheets subsequently, and, partly from specification sheets, become obvious, perhaps understand through embodiment of the present invention.The object of the invention can be realized through the structure that in the specification sheets of being write, claims and accompanying drawing, is particularly pointed out and obtained with other advantages.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification sheets, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 removes the electrical principle scheme drawing of the control circuit of automobile rearview mirror rainwater for utilize super sonic according to the present invention.
In conjunction with accompanying drawing, Reference numeral is following in the embodiment of the invention:
The 1-ignition lock; The 2-wiper control switch; The 3-storage battery; 4-often drives the rain shaving electrical machine control relay; The 5-rain shaving electrical machine; 6-often drives the ultrasonic generator control relay; The 7-ultrasonic generator.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
According to the embodiment of the invention, a kind of control circuit that utilizes super sonic to remove the automobile rearview mirror rainwater is provided.As shown in Figure 1, present embodiment comprise storage battery 3, ignition lock 1, wiper control switch 2, often open rain shaving electrical machine control relay 4, rain shaving electrical machine 5, often drive ultrasonic generator control relay 6 and ultrasonic generator 7.Here, ultrasonic generator 7 is near automobile rearview mirror setting (be ultrasonic generator 7 be arranged in automobile rearview mirror near).
Wherein, the negative earth of above-mentioned storage battery 3; The positive pole of storage battery 3; Ground connection through ignition lock 1, wiper control switch 2 and after often opening the magnet coil of rain shaving electrical machine control relay 4 successively; Often open the control contact and the rain shaving electrical machine 5 back ground connection of rain shaving electrical machine control relay 4 successively, and often open ultrasonic generator control relay 6 and ultrasonic generator 7 back ground connection successively; It is parallelly connected with the magnet coil of often driving rain shaving electrical machine control relay 4 often to open the magnet coil of ultrasonic generator control relay 6.
When rainy weather driving and Wiping device unlatching; Ignition lock 1 is all closed with wiper control switch 2; Connect and often open rain shaving electrical machine control relay 4 and the magnet coil terminal circuit of often driving ultrasonic generator control relay 6; The contact switch terminal of two relays (promptly often drive rain shaving electrical machine control relay 4 and often drive ultrasonic generator control relay 6) is all closed; Thereby connect the power circuit of rain shaving electrical machine 5 and ultrasonic generator 7, the rainwater on the front windshield is removed in rain shaving electrical machine 5 work; Simultaneously, ultrasonic generator 7 work utilize the hypracoustic vibration to remove the rainwater on the automobile rearview mirror, to ensure the rainy day traffic safety.
At fine day, because wiper control switch 2 is not closed, rain shaving electrical machine 5 is not worked, and ultrasonic generator 7 can not worked yet.
In sum; The super sonic that utilizes of various embodiments of the present invention is removed the control circuit of automobile rearview mirror rainwater since comprise storage battery, ignition lock, wiper control switch, often open rain shaving electrical machine control relay, rain shaving electrical machine, often drive ultrasonic generator control relay and ultrasonic generator; Can utilize the hypracoustic vibration to remove the rainwater on the automobile rearview mirror, to ensure the rainy day traffic safety; Thereby can overcome the not good and big defective of potential safety hazard of result of use in the prior art, with the advantage that realizes that result of use is good and potential safety hazard is little.
