The Research for the Piezoelectricity Rain-Removing System of Rearview Mirror

Abstract:

In order to solve the problem of blurry sight made by rain drop on the rearview mirror on rainy day, a rain-removing device making use of piezoelectric vibrator is put forward. Design the structure of the rain-removing device, build its finite element model and modal analysis for the piezoelectric vibrator is done. Piezoelectric rain-removing device prototype is manufactured and amplitude of the mirror is tested with different voltages and frequency. At last rain-removing effect for the rear mirror is measured with varies of angle at which piezoelectric vibrator is installed. The proportion of the removed rain drop is 80% when piezoelectric vibrator angle is 60° and the voltage and frequency on the piezoelectric vibrator is100V and 800Hz respectively.
