The first end 41 of the drive rod 15 is located outside the turntable 9, and the first end 43 of the drive rod 19 is also located outside the turntable 9. The turntable 9 is located between the main housing 101 and the first ends 41 and 43 of the drive rods 15 and 19.

[0039] The adjustment device described above also includes a second adjustment mechanism. As shown in Figures 8 and 9, the second adjustment mechanism includes transmission pins 25 and 26 (also referred to as the first transmission pin 25 and the second transmission pin 26, respectively), which are transmission-connected to the second dampers 6 and 7. The transmission pins 25 and 26 are located on the inner side of the turntable 9 and between the main housing 101 and the turntable 9. Specifically, the transmission pin 25 is transmission-connected to the upper-blowing damper or the second damper 6, and the transmission pin 26 is transmission-connected to the lower-blowing damper or the second damper 7.

[0040] As shown in Figure 2, 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.

[0041] As shown in FIG. 3 , 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 .

[0042] As shown in FIG2 , the air distribution system 2 further includes a bracket 28, which is connected to the main housing 101, for example, 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 position of the drive rods 15 and 19, as described below.

[0043] 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.

[0044] As shown in Figure 4 , the drive gear 4 rotates around a gear shaft 37 mounted on the bracket 28, thereby driving the turntable 9 via an intermediate gear. As shown in Figure 5 , an intermediate gear 38 is located at the center of the turntable 9 and meshes with the drive gear 4. Furthermore, as shown in Figure 4 , the bracket 28 has an opening that exposes the intermediate gear 38. The power of the motor 3 is transmitted to the main body of the turntable 9 via the drive gear 4 and the intermediate gear 38.

[0045] As shown in Figures 6 and 7, the bracket 28 is provided with a first limiting portion 30, 32, 33, 29a and a second limiting portion 29b. The first limiting portions 30, 32, 33, 29a are used to abut against the top surfaces 47, 48 of the drive rods 15, 19, and the second limiting portion 29b is used to abut against the side surface 49 of the drive rod 15. Specifically, the first limiting portions 30, 29a abut against the top surface 47 of the drive rod 15 to limit the drive rod 15 in the direction toward the main housing 101; the first limiting portions 32, 33 abut against the top surface 48 of the drive rod 19 to limit the drive rod 19 in the direction toward the main housing 101. The second limiting portion 29b limits the drive rod transversely to the extension direction of the drive rod 15, pressing the drive rod 15 toward the corresponding damper. For example, the first limiting portions 30, 32, 33 can be U-shaped grooves that accommodate the corresponding drive rods 15, 19. For example, the second stopper 29b is a bump, specifically, a protrusion extending from the first stopper 29a along the side surface 49 of the drive rod 15. As shown in FIG7 , the housing 1 further includes a hook 31 disposed on the main housing 101 and configured to hook the drive rod 19 toward the main housing 101. The provision of the stopper and the hook ensures that the drive rod follows a predetermined path during sliding.

[0046] Referring again to FIG6 , the first end 41 of the drive rod 15 is spaced apart from the main housing 101 relative to the second end 42 of the drive rod 15. Referring again to FIG7 , the first end 43 of the drive rod 19 is spaced apart from the main housing 101 relative to the second end 44 of the drive rod 18. Furthermore, an inclined arm 45 is provided between the first end 41 and the second end 42 of the drive rod 15, and an inclined arm 46 is provided between the first end 43 and the second end 44 of the drive rod 19. Considering that the turntable 9 has tracks on both the inner and outer sides and therefore has a certain thickness, an inclined arm is provided to connect the drive rod to the outer side of the turntable. This design can make the structure simple and compact.

[0047] As shown in Figures 8 and 9, a transmission pin 25 is provided on a transmission wheel 23, which is in transmission connection with the upper-facing damper or the second damper 6. A transmission pin 26 is provided on the lower-facing damper or the second damper 7. Specifically, the transmission wheel 23 is connected to the rotating shaft 24 of the second damper 6, for example, by meshing with a rotating shaft gear on the rotating shaft 24 of the second damper 6. The transmission pin 26 is provided on the rotating shaft 27 of the second damper 7, specifically, on the rotating shaft gear of the rotating shaft 27 of the second damper 7.

[0048] As shown in Figures 5 and 10 , first tracks 11 and 12 for drive rods 15 and 19 are provided on the outside of the turntable 9, and second tracks 13 and 14 for drive pins 25 and 26 are provided on the inside of the turntable 9. Specifically, first track 11 for drive rod 15 and first track 12 for drive rod 19 are provided on the outside of the turntable 9, with first track 11 located inside first track 12. Furthermore, second track 13 for drive pin 25 and second track 14 for drive pin 26 are provided on the inside of the turntable 9, with second track 13 located inside second track 14.

[0049] For example, the drive levers 15 and 19 may be in the form of racks, with pins 17 and 21 disposed on their first ends 41 and 43, respectively, capable of sliding within the associated first rails 11 and 12, and teeth 18 and 22 disposed on their second ends 42 and 44, respectively, for engaging with the first dampers 5 and 8. Specifically, as shown in FIG5 , the first end 41 of the drive lever 15 is provided with a pin 17 capable of sliding within the first rail 11, while the first end 43 of the drive lever 19 is provided with a pin 21 capable of sliding within the first rail 12. Furthermore, as shown in FIG6 , the second end 42 of the drive lever 15 is provided with teeth 18 for engaging with the defrost damper or the first damper 5, more specifically, the rotational shaft 16 of the first damper 5. As shown in FIG7 , the second end 44 of the drive lever 19 is provided with teeth 22 for engaging with the foot damper or the first damper 8, more specifically, the rotational shaft 20 of the first damper 8.

[0050] As shown in Figures 8 and 9, a stopper 34 is further provided on the transmission wheel 23, and a first stopper 35 and a second stopper 36 are provided on the main housing 101. The stopper 34 moves between the first stopper 35 and the second stopper 36. 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 restricted to a certain range, preventing the second damper 6 from excessive rotation.

[0051] 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 and foot blowing mode, face blowing and foot blowing defrost mode, exhaust 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 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 have different temperatures. Different rotation angles of the turntable 9 can correspond to different modes, depending on the specific design.

[0052] The disclosed air conditioning module utilizes tracks on both sides of the turntable, requiring only a single micromotor to achieve nine air conditioning modes. Furthermore, the module utilizes two drive rods driven by the outer turntable track, while the inner turntable track drives two transmission pins, enabling control of the opening, closing, and degree of opening of the defrost damper, upper and lower face dampers, and foot damper, thereby achieving nine air conditioning modes with a simple and compact structure. Furthermore, the disclosed air conditioning module can better regulate vehicle interior parameters such as temperature, humidity, airflow velocity, and air cleanliness, providing a fresh and comfortable interior environment for passengers.

[0053] The present disclosure may also provide a vehicle including the above-mentioned air-conditioning module, and the vehicle thus has the various advantages described above with respect to the air-conditioning module.

[0054] In addition, the technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art can also make other combinations between the technical features according to the purpose of the invention to achieve the purpose of this disclosure.
