Automobile air conditioner system damper controller

Abstract

The invention belongs to the field of automobile air conditioning techniques, specifically a throttle control device of an automobile air conditioning system. The invention comprises a turn knob, a control box, a draw wire (9), a transmission mechanism and a guiding device both driven by the draw wire (9), and a plate-shaped throttle (4) slidably engaged with the guiding device. The transmission mechanism drives the throttle (4) to move in the direction defined by the guiding device The invention uses the sliding throttle to replace the conventional rotating throttle and overcomes the frictional force instead of the air flow resistance when opening or closing the sliding throttle, so that the rotational torque is significantly reduced and the operability of the turn knob is efficiently improved.

Description

technical field

[0001] The invention belongs to the technical field of automobile air-conditioning, and in particular relates to a damper control device of an automobile air-conditioning system. Background technique

[0002] At present, it is more common for lower-configuration automotive air-conditioning control boxes to drive the air door on the HVAC (heating, ventilation, and air conditioning) assembly by wire drawing, and its cost is also low. The so-called wire drawing drive refers to the rigid coaxial connection between the knob on the air conditioner control box and the gear mechanism on the back of the control box. One end of the hard wire drawing used to drive the HVAC damper is connected to the gear mechanism of the control box, and the other end is connected to the damper or the damper dial mechanism. When turning the knob, the gear mechanism on the control box drives the wire drawing movement, and the wire drawing drives the damper to rotate, so as to achieve the...
