Background technology
Current air conditioning for automobiles fresh air control device mainly comprises the control actuator, described control actuator substantially adopts the operational mode of forward and backward to drive opening of new wind air door and closes, like this because will realize by the commutation of power supply positive and negative electrode the forward and backward of actuator, the rotating work frequently of motor and transmitter, can cause the life-span of motor and transmitter greatly to reduce, and the control accuracy of the control actuator of this structure of prior art is not high yet.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of control accuracy air conditioning for automobiles higher and that service life is longer new wind damper control.
The technical scheme that the utility model adopts is: the new wind damper control of a kind of air conditioning for automobiles, it comprises that one for providing the one direction rotatory force and controlling the control actuator of each rotational angle and the air-door opening-closing device that the loop control air-door opening-closing is provided for the one direction rotatory force that will control actuator and provide, described control actuator comprises casing, servomotor, reduction box, and controller, described servomotor, reduction box and controller all are arranged in casing, described servomotor output shaft is connected with reduction box by transmission device, the output shaft of described reduction box is provided with transmission arm, described reduction gearbox output shaft all is connected with the air-door opening-closing device with transmission arm, described controller is electrically connected to servomotor.
Described air-door opening-closing device comprises that oval rotating disk, fan-shaped new wind rotate air door and is connected with oval rotating disk and new wind rotation air door the fork that rotates air-door opening-closing for driving new wind respectively, described oval rotating disk is connected with reduction gearbox output shaft and transmission arm, and described oval rotating disk circumference is provided with the oval gathering sill for fork one end motion, described fork one end is slidably fitted in described oval gathering sill, it is hinged that the described fork other end and fan-shaped new wind rotate air door, and described fork middle and lower part is also hinged with casing.
Described servomotor two end supports face is provided with damper.
Adopt above structure compared with prior art, the utlity model has following advantage: the angle of accurately controlling the servomotor one-directional rotation by controller, control so more accurate, then by transmission device and reduction box, rotatory force is reduced, guaranteed like this stable of operation, it is constant that rotating speed and moment of torsion are exported, finally by the air-door opening-closing device, changing unidirectional rotatory force into power that the new wind of loop control rotates air-door opening-closing, servomotor only needs to rotate and just can well control the keying that new wind rotates air door towards same direction always like this, the service life of servomotor is just longer like this, and on servomotor two end supports face, damper is set, the absorption of vibration energy in the time of can guaranteeing the servomotor high-speed cruising like this, make the servomotor operation more steady.
