Problems solved by technology

When the air conditioner is running and the damper is closed, it is necessary to open the damper when the air conditioner blower is working. The damper needs to rotate around the rotation axis inside the air outlet. During this rotation, the damper must overcome the thrust generated by the wind to open the air outlet. , and this thrust will be transmitted to the drawing through the damper control mechanism, and then to the knob through the drawing, which will eventually cause the torque to increase when the knob is turned, making the operator feel uncomfortable and inconvenient to operate.

Embodiment Construction

[0009] As shown in Figure 1, a damper control device for an automobile air-conditioning system includes a knob, a control box, and a wire drawing 9. The device also includes a transmission mechanism and a guide device driven by the wire drawer 9. The plate-shaped damper 4 and the guide device are sliding Cooperate, the transmission mechanism drives the damper 4 to move along the direction defined by the guide device.

[0010] In the present invention, the operator turns the knob, the knob drives the control box, and then the control box drives the drawing wire 9, and then the drawing wire 9 makes the damper 4 slide along the direction defined by the guide device through the transmission mechanism, thereby realizing changing the rotational movement of the damper 4 to sliding. Movement reduces the driving force of the damper 4, thereby greatly improving the operating feeling of the knob.

[0011] There are many ways to realize the transmission mechanism and guide device. For exa...

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...
