The purpose of the improvement of the new type of automobile air-conditioning damper automatic actuator is to overcome the above shortcomings and provide an electric method to automatically control the opening, rotation and stop of the damper, which can be stopped at any position of the rotation range, with low noise, small size, convenient installation, and structure. Simple car air-conditioning damper actuator.
An automatic actuator for automobile air conditioning damper realized by the following technical solutions, including DC motors, gears, worms, brushes, circuit boards, electronic components, control signal lines, and power lines; its main technical feature is that the actuator is powered by a circuit The main control part, the power component part, the mechanical transmission part, and the motor part are composed. The main control part is composed of a main chip and an input signal conversion circuit; the mechanical transmission part is composed of a worm, a gear, and two electric brushes. The output transmission interface is composed of gears; the power component part is composed of a diode, a triode, a resistor, a voltage regulator tube and a PTC with current protection; the circuit board has a carbon film with a linear resistance value in addition to a circuit Floor.
The new auto air-conditioning damper automatic actuator is based on an integrated circuit as the main controller, which directly controls the position of the damper motor according to the control signal and the feedback signal of the damper motor. Its positioning accuracy is high, and the response is sensitive; it can not only realize the control of the forward and reverse rotation and stop rotation of the damper motor, but also has the protection functions of stall protection, short circuit protection, overheat protection, overvoltage protection, and short circuit monitoring, which improves the safety of the system. Sex. The air door automatic actuator of the utility model has the advantages of low noise, sensitive response, energy saving and safety.
