Abstract
A motor vehicle rear viewing mirror with removing rainwater unit is provided and comprises a rear viewing mirror slice. The characteristic lies in that a piezoelectric ceramic layer is compounded on the back of the mirror slice. The piezoelectric ceramic layer is connected with the power source through a ultrasonic wave generator. The utility model has the advantage that as soon as rainwater falls onto the mirror surface, the ultrasonic wave will remove the rainwater and even the dirt. No rainwater wiper and transmission mechanism that drives the wiper are needed.
Description
Technical field
The utility model relates to a kind of automobile rearview that can remove rainwater, is mainly used in transportation meanss such as automobile or engineering truck.
Background technology
Existing self-propelled vehicle, as automobile, its back mirror curette that do not rain usually, this has brought many inconvenience for the rainy day safe driving, for example, be difficult to by back mirror clearly observe in good time the rear driving, pedestrian, overtake other vehicles or the obstacle situation.Before this, the applicant had once submitted to name to be called the patent application of the rearview mirror wiper blade device of self-propelled vehicle, application number: 02278073.4.Though it scrapes off rainwater effectively in the time of can driving a vehicle in the rainy day, it also needs a windscreen wiper and drives the transmission device of windscreen wiper, and structure is comparatively complicated.
The utility model content
Technical problem to be solved in the utility model is: a kind of automobile rearview that can remove rainwater is provided, it utilizes the sonic oscillation characteristic after the piezoceramic energising, can remove the rainwater of lens surface under the situation of the transmission device that need not windscreen wiper and driving windscreen wiper effectively.
The technical scheme that solves this technical problem is: a kind of automobile rearview that can remove rainwater, comprise rear view mirror lens, and it is characterized in that: compound piezoceramics layer at the back side of eyeglass, this piezoceramics layer links through ultrasonic generator and power supply.
And eyeglass can be the minute surface plated film layer that is attached to the piezoceramic laminar surface.
And eyeglass can be bonding with piezoceramics layer.
In the technical program, because the back side of eyeglass is compound piezoceramics layer, its dynamic piezoelectric effect makes it can produce the super sonic of broad spectrum, be attached to the moment of lens surface when rainwater, can rapidly rainwater even dirt be removed by super sonic, need not the transmission device of windscreen wiper and driving windscreen wiper.
Description of drawings
Fig. 1 is the scheme drawing in back mirror front.
Fig. 2 is the schematic cross-section at the A-A place of Fig. 1.
The specific embodiment
With reference to Fig. 1, the automobile rearview that can remove rainwater described in the utility model comprises back mirror 1 eyeglass 2, it is characterized in that: compound piezoceramics layer 3 at the back side of eyeglass 2, this piezoceramics layer 3 links through ultrasonic generator 5 and power supply 6.
Described piezoceramic is preferably selected existing lead titanates and the lead titanate piezoelectric ceramics that produces high medium frequency for use.Ultrasonic generator 5 can be selected existing commercially available product for use.Master cock 4 can be located at the instrument desk of operator's compartment.
Further technical scheme can be: eyeglass 2 is the minute surface plated film layers that are attached to piezoceramics layer 3 surfaces.
Further technical scheme can also be: eyeglass 2 can be bonding with piezoceramics layer 3.This eyeglass 2 can be glass or organism glass eyeglass, also can be the medal polish eyeglass.
