Multi-module variable automobile rearview mirror wiper system

Abstract

The invention discloses a multi-module variable automobile rearview mirror wiper system. The system comprises a temperature and humidity sensor module part, a step motor module part, a single-chip microprocessor control part, a gear reduction mechanism and a telescopic rod mechanism, and structurally comprises a temperature and humidity sensor, an A/D (Analog/Digital) converter, a step motor, a key, an STC89C51 single-chip microprocessor, a gear and a telescopic wiper bar. When detection shows that the wiper system is required to work by temperature and humidity of an external environment and a signal is received that a driver turns on the wiper system, the wiper system starts to work. Since manual and automatic regulation and control are performed simultaneously, the wiper system has great advantage in safety and reliability. The wiper can rotate and stretch, so the wiper has extremely high degree of freedom, the swept region is large, meanwhile the rotation degree and the stretch degree can be adjusted according to requirements, and the adaptability is high. A heating device can also be optionally arranged on middle and high-grade automobiles, so the wiping effect is stronger.

Description

technical field [0001] The invention relates to an automobile rearview mirror wiper system. Background technique [0002] Judging from the current market, there are few rearview mirror wiper works and designs, and they are not perfect. There are not many products on the market that can realize cleaning or prevent dripping on the rearview mirror. In terms of their functions, they are mainly divided into heating types. Rearview mirrors and rearview mirror shades. Nowadays, the rearview mirror is heated to remove fog and rain, but according to the use effect, the effect of fog removal has been achieved, but the effect of rain removal is not ideal. There are also some mechanical rain removal devices, which only stay on the design and have not been recognized and promoted by the market. Moreover, the installation cost of the heated rearview mirror is relatively high, and the optional cost for high-end cars needs about 3,000 yuan. If you modify the rearview mirror heater yours...

AI Technical Summary

Problems solved by technology

Domestic research includes rearview mirror wiper, controllable rearview mirror protective cover, multifunctional vehicle rearview mirror, etc., their operation is complicated, the cost is high, the drying effect is not obvious, the appearance is not beautiful, the volume is large, most of them It is only aimed at mid-to-high-end cars, but our invention makes up for their shortcomings and broadens the scope of use. It can not only dry fog, rain and frost, but also remove dust and smoke.
