[0018] The series air damper structure provided in this embodiment is as Figure 1The following is a schematic diagram of its internal structure, including a fresh air housing 1. Inside the fresh air housing 1, coaxially installed are a first sleeve shaft 21, a second sleeve shaft 31, and a third sleeve shaft 41. The three sleeve shafts are sequentially sleeved inside the aforementioned one, and at the same time, the ends of the three sleeve shafts penetrate through the fresh air housing 1 and extend to the outside. Inside the fresh air housing 1, the first sleeve shaft 21, the second sleeve shaft 31, and the third sleeve shaft 41 are respectively connected to a first air damper 2, a second air damper 3, and a third air damper 4. Thus, when the first sleeve shaft 21 rotates, it drives the first air damper 2 to deflect; when the second sleeve shaft 31 rotates, it drives the second air damper 3 to deflect; when the third sleeve shaft 41 rotates, it drives the third air damper 4 to deflect. A fresh air middle partition is provided between each air damper. Outside the fresh air housing 1, a motor 5 and a mode disk 6 connected to the output end of the motor 5 are also connected. The motor 5 is used to drive the mode disk 6 to rotate, and then drive each sleeve shaft to rotate.

[0019] Specifically, Figure 2 This is a schematic diagram of the transmission structure in this embodiment. At the bottom of the mode disk 6, a first track 67 and a second track 68 are provided. The trajectories of the tracks are preset according to the requirements of each air damper. On the fresh air housing 1, a second fork gear 61 and a first fork gear 63 are rotatably connected. At the same time, at the end of the second sleeve shaft 31, a second sleeve shaft gear 62 is connected and meshes with the second fork gear 61. At the ends of the first sleeve shaft 21 and the third sleeve shaft 41, a first sleeve shaft gear 64 and a third sleeve shaft gear 65 are respectively connected, and the first sleeve shaft gear 64 and the third sleeve shaft gear 65 are simultaneously meshed with the first fork gear 63. So that when the second fork gear 61 rotates, it drives the second sleeve shaft gear 62 and the second sleeve shaft 31 to rotate; when the first fork gear 63 rotates, it drives the first sleeve shaft gear 64 (and the first sleeve shaft 21) and the third sleeve shaft gear 65 (and the third sleeve shaft 41) to rotate, realizing that when the mode disk 6 rotates, it drives the three air dampers to rotate through the second fork gear 61 and the first fork gear 63, and the rotation angles of the first air damper 2 and the third air damper 4 are equal.

[0020] Specifically, as Figure 3 shown, the principle that the mode disk 6 drives the second fork gear 61 and the first fork gear 63 to rotate is that on both the second fork gear 61 and the first fork gear 63, a track fork member 66 is connected. One end of the track fork member 66 extends into the first track 67 and the second track 68 respectively. The trajectories of the first track 67 and the second track 68 are preset. Thus, when the mode disk 6 rotates, the two track fork members 66 deflect in the tracks respectively, and then drive the second fork gear 61 and the first fork gear 63 to deflect respectively.

[0021] In some other embodiments, the series damper structure in this embodiment can be installed in an automotive air conditioner. The motor 5 and the mode disk 6 can be installed inside the automotive air conditioner and are used for synchronous adjustment of multiple dampers in the air conditioner. The motor 5 drives the mode disk 6 to rotate, driving the second fork gear 61 and the first fork gear 63 to deflect respectively, and then realizing the simultaneous deflection of the three dampers. The trajectories of the first track 67 and the second track 68 can be designed according to the requirements of the damper angles.

[0022] It should be noted that the first damper 2, the second damper 3, and the third damper 4 in this embodiment are only examples of the solution of the present utility model. In some other embodiments, more dampers can be added to meet different damper adjustment requirements of the air conditioner, as long as the respective sleeve shafts connecting the dampers are coaxial and the sleeve shaft gears are meshed with the corresponding fork gears.

[0023] In addition to the above embodiments, the present utility model can also have other embodiments; all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
