Self-water removal device for automobile rearview mirror

Abstract

The invention discloses a self-water removal device for automobile rearview mirror which comprises a rearview mirror body and a mirror surface embedded in the rearview mirror body; a heating water removal device is arranged on the mirror surface; a cylindrical cavity and a cavity are formed in the rearview mirror body; the cylindrical cavity is located above the cavity; a sliding rod is slidably connected to the center of the top of the cylindrical cavity in a penetrating mode, the upper end of the sliding rod penetrates through the top of the rearview mirror body and is welded with a wing plate, piezoelectric ceramic is fixedly connected to the bottom of the cylindrical cavity, and an energy storage device is arranged in the cylindrical cavity. The device has the advantages that after thepiezoelectric ceramic is impacted, an electromagnet is electrified to generate magnetism, air above a piston plate is compressed, and then high-speed airflow attached to the mirror surface is blown out from the air outlet hole in the upper portion of the mirror surface through an air guide pipe, so that water on the mirror surface is rapidly removed; meanwhile, circuits of a first conductive strip and a second conductive strip are conducted through water drops, so that the piezoelectric ceramic performs point heating on the water drops, and the water removal efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile rearview mirror self-water removal device. Background technique [0002] The rearview mirror is a tool for the driver to directly obtain external information such as the rear, side and bottom of the car while sitting in the cab seat. For the convenience of the driver's operation, to prevent the occurrence of driving safety accidents, and to ensure personal safety, all countries have stipulated that rearview mirrors must be installed on cars, and all rearview mirrors must be able to adjust their direction. [0003] When the car is driving on a rainy day, the mirror surface of the rearview mirror will be stained with raindrops, forming water mist, which will affect the driver's line of sight and make it impossible to prepare for judging the situation of the vehicle behind, thus causing potential safety hazards. Currently, the existing rearview mirror dewateri...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the electric heating of the rearview mirror in the prior art not only consumes a lot of energy and wastes electric energy, but also heats the mirror as a whole, the efficiency is low, and the heating cannot effectively remove the continuously falling The problem of water droplets, and a kind of car rearview mirror self-water removal device is proposed
