Automotive air-conditioner with vent and air-mixing door interlocking mechanism |
摘要 |
A motor vehicle air-conditioner having a structure that reduces production costs. Main and sub air-mixing doors and an inner-air FOOT door are mechanically interlocked with a single air-mixing door actuator. The shape of an engagement hole of a main link plate of a door-interlock device is formed to correspond to an operation pattern to rotate the main and sub air-mixing doors from MAX COOL to MAX HOT in an interval where a servomotor opening degree is from 0% to 80%. The shape of an engagement hole of a main link plate is such that the plate functions as a lost motion link plate that corresponds to an operation pattern to rotate the inner-air FOOT door from a fully closed state to a fully open state in an interval where the servomotor opening degree is from 80% to 100%. As a result, opening of the inner-air FOOT door becomes difficult even when the main and sub air-mixing doors are opened, and so leakage of conditioned air from a foot vent can be prevented.
