Electronically adjusted vehicle mirror - has two electric motors to adjust in two planes using only four wires

摘要

A rear view mirror with electronic adjustment has a metal or plastics box fitted to the outside of the vehicle. This houses two motors, one horizontal and the other vertical. Reversal is done by reversing the feed polarity. Adjustment of the mirror cannot be done from outside. The sealing of the interior mechanism is give by a PVC film. Control is done by a shaft and grip. This works with four micro switches to give left and right, up and down adjustments to the mirror. Only four wires are needed.
