AIR PATH CONTROL SWITCH FOR A VEHICLE WITH AN AIR VOLUME CONTROL FUNCTION CAPABLE OF INDIVIDUALLY CONTROLLING THE AIR VOLUME OF MULTIPLE AIR PATHS

摘要

PURPOSE: An air path control switch for a vehicle with an air volume control function is provided to enable a driver to freely set and change the air volume of an air conditioner and a heater of a vehicle. ;CONSTITUTION: An air path control switch for a vehicle with an air volume control function comprises an air path selection switch(103), an air volume control slide bar(101), a blowing fan, a blowing duct, air paths, air volume control valves, a motor, an encoder, a motor driver, and a controller. The air volume control slide bar is attached on the air path selection switch and controls air volume. The blowing duct passes through air passing through the blowing fan. The air paths are connected from the blowing duct to a blowing port. The air volume control valves are installed in the air paths and controls air volume. The motor rotates the air volume control valves. The encoder senses the rotation of the motor. The controller powers the motor through the motor driver.;COPYRIGHT KIPO 2011
