Up and down moving mechanism for an air spoiler associated with a movable grill

摘要

An up and down moving mechanism for an air spoiler associated with a movable grill for reducing air resistance is disclosed. The moving mechanism includes a speed sensor detecting the driving speed and transmitting a signal to a control circuit. A thermostat connects to a linkage for controlling the opening and closing of the movable grill in response to the water temperature in a radiator. A motor rotates in response to instructions transmitted from the control circuit and opens a gap between the air spoiler and a bumper. A first circuit detects the position of a thermostat rod and transmits a signal to the control circuit to lift the air spoiler. A second circuit detects a position of a motor rod and transmits a signal to the control circuit to stop a rotation of the motor.
