Background technology
Automobile rearview mirror is the pith of automobile active safety configuration, is moveing backward, is stopping, overtakes other vehicles and most important to aspects such as the understanding of back vehicle condition, assurances.Therefore the vision of back mirror is clear is absolutely necessary in vehicle operating.Generally, the automobile back mirror that is in operation all is totally clearly, but on rainy day, especially with the rainy day of blowing, raindrop are often trickled down on automobile rearview mirror, make backsight visual field a slice fuzzy, make chaufeur can't understand the situation of vehicle back and both sides, thereby the initiation traffic accident, light damaged vehicle then, heavy then car crash.
Existing in the world automobile vendor, the automobile rearview mirror raindrop are not influenced traffic safety and provide absolute feasible method, these manufacturers just extend, and to carry out part rainproof for the shell upper edge of back mirror, but DeGrain, can only the light rain under the windless condition be blocked, and, influence driver's sight line owing to the lengthening of shell upper edge.For the rain method of removing of automobile rearview mirror, also the someone proposes various schemes, comprising the patent of having applied for, but effect is undesirable or implement comparatively difficulty because these scheme implementations get up, and does not realize on vehicle that these schemes comprise: electro heat, wiper, hair dryer etc.
Summary of the invention
The invention provides a kind of piezo-electricity driven automatically raindrop removing automobile rear view mirror, remove the backsight safety problem that occurs owing to raindrop are difficult to solve present automobile rearview mirror.Technical scheme of the present invention is: comprise back-mirror housing, this back-mirror housing internal fixation connects the back mirror body and adjusts rotating disc, it is characterized in that: the base terminal pad outside of piezoelectric vibrating device and this back mirror body adjustment rotating disc are captiveed joint, and the rear-view mirror body reaction plate of this piezoelectric vibrating device is captiveed joint with the backsight minute surface.
The structure of piezoelectric vibrating device of the present invention is that piezoelectric element is captiveed joint with the piezoelectric element permanent seat, and the piezoelectric element permanent seat is connected with automobile rearview mirror mirror body reaction plate; Piezoelectric element is captiveed joint with the piezoelectric element strut bar, the piezoelectric element strut bar other end is captiveed joint with elastic adjusting strip, elastic adjusting strip is fixed on the base terminal pad, the base terminal pad is captiveed joint with back mirror body adjustment rotating disc, base terminal pad inner peripheral is evenly fixing or fix three or four resilient mounting sheets symmetrically, and the resilient mounting sheet other end is captiveed joint with automobile rearview mirror mirror body reaction plate.
One embodiment of the present invention are: when piezoelectric element was twin lamella or single-chip structure, its shape can be annular arrangement, Y font, criss-cross.
One embodiment of the present invention are: elastic adjusting strip is disc, Y shape, criss-cross or other rectangular distribution multijaw shapes.
One embodiment of the present invention are: the resilient mounting sheet is equidirectional along base terminal pad periphery, with angle tilt rectangular distribution or symmetrical distribution.
One embodiment of the present invention are: piezoelectric element is the piezoelectric vibrator column structure, at this moment, produces ultrasonic vibration.
Its principle of work is: when the voltage that applies certain frequency to piezoelectric element makes its bending vibrattion, when perhaps applying high frequency voltage and make it produce ultrasonic vibration to piezoelectric element, the vibration that deforms simultaneously of piezoelectric element, elastic adjusting strip and resilient mounting sheet, because the base terminal pad maintains static,, this resultant vibration produces compound vibration so can driving automobile rearview mirror mirror body reaction plate.Equidirectional when the resilient mounting sheet along base terminal pad periphery, during with the angle tilt rectangular distribution, this compound motion is up and down and torsion oscillations synthetic, the raindrop on automobile rearview mirror surface is formed along peripheral elliptic motion, thereby tumble minute surface.When the resilient mounting sheet is symmetrically distributed along the base terminal pad is peripheral, produce up-down vibration, make raindrop directly break away from the automotive rear-view minute surface.When piezoelectric element adopts the piezoelectric vibrator structure, can also produce ultrasonic atomization, make raindrop directly resolve into water smoke and break away from the automotive rear-view minute surface.
The invention has the advantages that: simple in structure, volume is little, power consumption is low, noise is little, it is obvious to remove the raindrop effect, can directly on existing automobile rearview mirror, install in addition, need not existing automobile rearview mirror is destroyed, this device and automobile rearview mirror are coupled as one, mechanism is simple, and propulsive effort is strong, also can realize effective work under low voltage, can successfully solve the rainy day driving mirror and remove the raindrop problem, fundamentally solve the backsight safety problem of rainy day driving.
