[0039] like Figure 2As shown, the air distribution system 2 further includes a motor 3. The air distribution system of the air conditioning module of the present disclosure includes only one motor 3 and can realize at least nine air conditioning modes.

[0040] like Figure 3 As shown, the adjusting device further includes a driving gear 4 , which is connected between the motor output shaft of the motor 3 and the turntable 9 to transmit the power of the motor 3 to the turntable 9 .

[0041] like Figure 2 As shown, the air distribution system 2 further includes a bracket 28, which is connected to the main housing 101, for example, fixed to the main housing 101 by screws. The drive rods 15 and 19 are located between the bracket 28 and the turntable 9. The bracket 28 can be used to limit the drive rods 15 and 19, as described below.

[0042] In addition, the motor 3 is mounted on the bracket 28, the turntable 9 is located inside the bracket 28, and the motor 3 is located outside the bracket 28. For example, the motor 3 is fixed to the bracket 28 by screws or the like.

In addition, there is an inclined arm 45 between the first end 41 and the second end 42 of the driving rod 15, and there is an inclined arm 46 between the first end 43 and the second end 44 of the driving rod 19. Considering that the turntable 9 is provided with tracks on both the inner and outer sides and therefore has a certain thickness, an inclined arm is provided to connect the driving rod to the outer side of the turntable. This design can make the structure simple and compact.

[0046] like Figure 8 and 9 As shown, the transmission pin 25 is arranged on the transmission wheel 23, and the transmission wheel 23 is transmission-connected with the upper blowing surface damper or the second damper 6. The transmission pin 26 is arranged on the lower blowing surface damper or the second damper 7.

The first stopper 35 and the second stopper 36 may be protrusions on the main housing 101. By providing the stopper and the stopper, the position of the second damper 6 can be limited within a certain range to prevent the second damper 6 from rotating excessively.

[0050] Through the above-mentioned air distribution system including a motor and a turntable, the air conditioning module of the present disclosure can realize the following modes: face blowing mode, face blowing foot blowing mode, face blowing foot blowing defrost mode, exhaust gas mode, foot blowing mode, first foot blowing defrost mode, second foot blowing defrost mode, defrost mode, and face blowing defrost mode. The damper opening in the exhaust gas mode is different from the damper opening in the simple foot blowing mode. The damper openings in the first foot blowing defrost mode and the second foot blowing defrost mode are different and the temperature is different. Different rotation angles of the turntable 9 can correspond to different modes, which depends on the specific design.

[0051] The air conditioning module disclosed in the present invention can realize nine air conditioning modes with only one micro motor by means of tracks arranged on both sides of the turntable. In addition, the air conditioning module disclosed in the present invention drives two driving rods through the outer track of the turntable, and drives two transmission pins through the inner track of the turntable, so as to control the opening, closing and opening degree of the defrost damper, the upper and lower face dampers and the foot damper, thereby realizing nine air conditioning modes, and the structure is simple and compact. Furthermore, the air conditioning module disclosed in the present invention can better adjust the air parameters such as the temperature, humidity, air flow speed, and air cleanliness inside the vehicle, and provide the passengers with a fresh and comfortable vehicle interior environment.

[0052] The present disclosure may also provide a vehicle including the above-mentioned air conditioning module, and the vehicle thus has various advantages as described above with respect to the air conditioning module.
