Abstract

The invention relates to an electronic thermostat actuating mechanism. Interference of cooling water flow speed fluctuation, mechanical vibration and the like of a lead screw circular truncated cone in a motor is eliminated through a worm wheel and worm self-locking principle. The electronic thermostat actuating mechanism comprises the motor, a first-stage transmission mechanism, a worm wheel and worm transmission mechanism, a bevel gear and the lead screw circular truncated cone. An output shaft of the motor is fixedly connected with a driving gear in the first-stage transmission mechanism.
