Description
Technical field
The present invention relates to automobile rearview mirror, more particularly to a kind of automobile rearview mirror driven based on ultrasonic travelling wave is except rain dress
Put.
Background technology
Automobile rearview mirror is requisite part in vehicle safety travel, when automobile is travelled on road, driver
By the backsight sem observation left and right vehicle wheel rear of the left and right sides and the running environment of side, to ensure vehicle in lane change or parking
Safety.At present, the rearview mirror of existing vehicle both sides all Wu remove rain function, it is difficult to ensure that sight line is clear.When driving a vehicle the rainy day,
Often cause rearview mirror blurred vision as rainwater is attached to rearview mirror surface, be unfavorable for the safe driving of automobile, therefore easily
Cause traffic accident.
Existing rearview mirror is except, in rain technology, some make the rain on minute surface using ultrasonic wave is produced after piezoelectric ceramics energising
Fog is dispelled by water atomization using the wind in running car, but the finite energy of ultrasonic wave and energy attenuation are very fast, very
Difficulty reaches the effect of atomization.Some hot-airs distributed using radiator based on evaporating principle, after driving air-flow to face
Visor blows, and its effect is not apparent.Some carry out transforming out rearview mirror wiper blade device according to wiper, and this causes the machine of rearview mirror
Tool structure is complex.
Content of the invention
It is an object of the present invention to provide a kind of rain removal device for automobile rearview mirror driven based on ultrasonic travelling wave, neither affects driver
The rainwater on rearview mirror can also be removed while sight line, it is ensured that in the safe driving of rainy day.
The present invention is achieved through the following technical solutions：
A kind of based on ultrasonic travelling wave drive rain removal device for automobile rearview mirror, including piezoelectric ceramics, silver layer, copper sheet, rearview mirror and
For producing the high-frequency ac power of high-frequency ac electric signal, the one side of piezoelectric ceramics carries out multidomain treat-ment using silver and forms silver
Layer, another side are bonding with copper sheet, collectively form partition type piezoelectric ceramics, and the partition type piezoelectric ceramics is fixed on rearview mirror inwall
Top edge, its one side bonding with copper sheet is close on the inwall of rearview mirror, and the high-frequency ac power is distinguished by wire
It is connected with silver layer and copper sheet circuit.
Further, the right hand edge of the silver layer depressed area is alignd with the left hand edge of shown copper sheet.
Further, shown piezoelectric ceramics, silver layer and copper sheet are arranged symmetrically, and the horizontal symmetry-line of three overlaps.
Further, the frequency that the high-frequency ac power is adopted is the first natural frequency of subregion piezoelectric ceramics.
Further, the thickness of the silver layer is 6 μm～10 μm.
Further, the thickness of the piezoelectric ceramics is 1mm～1.5mm.
Further, the thickness of the copper sheet is 0.1mm～0.2mm.
The present invention is had the following advantages and effect with respect to prior art：
The present invention only needs piezoelectric ceramics, silver layer, copper sheet and high-frequency ac power, with simple structure, small volume, be easily installed,
Dismounting and the advantage that safeguards.
It is an advantage of the invention that when rainy, automobile rearview mirror surface attachment raindrop cause blurred vision, the object of the invention
It is the raindrop slide downward for making to be attached to rearview mirror, so that the getting a clear view of rearview mirror, it is ensured that safe driving.
Present invention efficiently solves automobile rearview mirror surface raindrop affect the problem of driving sight, with good market
Prospect.
