Abstract:
A baffle controller for moving a baffle disposed within an HVAC outlet housing between an open position and a closed position to control airflow through an HVAC outlet in a vehicle includes a Shape Memory Alloy (SMA) actuator that is controlled and actuated by an electrical signal. The SMA actuator rotates a main lever that rotates a valve plate. The valve plate is attached to the baffle such that the baffle rotates with the valve plate. The baffle controller may include a position biasing device that increases a position holding ability of the baffle controller, and a cut-off switch that interrupts the electrical signal to the SMA actuator to prevent over-rotating the baffle.
