[0002] In a passenger car air-conditioning system, the function of the air damper is to control the air flow and distribution to achieve different air-conditioning modes. When the traditional air damper structure operates, there may be problems of jitter and noise. To solve these problems, an air-conditioning system air damper structure with a damping structure is needed. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides an air-conditioning system air damper structure with a damping structure. By installing a damping structure on the air-conditioning box housing, a good buffering effect can be achieved when the air damper main body performs the opening and closing actions, reducing the vibration and noise generated by the impact on the air-conditioning box housing during the movement of the air damper.

[0004] The air-conditioning system air damper structure with a damping structure in this solution includes an air-conditioning box housing and an air damper main body assembled therein, and further includes at least one damping structure connected to the air-conditioning box housing. The damping structure includes a damper and a damper installation assembly for positioning it. The damper installation assembly is fixedly connected to the air-conditioning box housing. Among them, the telescopic end of the damper is located on the deflection side of the air damper main body, so that when the air damper main body deflects back and forth, the side wall of the air damper main body on the deflection side squeezes or moves away from the telescopic end of the damper.

[0005] The further limited technical solution of the utility model is:

[0006] Further, the damper installation assembly includes a damper installation bottom plate and a damper pressing plate. The damper installation bottom plate is fixedly connected to the air-conditioning box housing, and the damper installation bottom plate is respectively provided with a first positioning end and a second positioning end to position both ends of the damper in the length direction. The damper pressing plate presses the damper on the damper installation bottom plate and is fixed by bolts.

[0007] Further, the bottom of the damper pressing plate is arc-shaped to fit the upper end of the damper.

[0008] Further, an air damper positioning hole connected to the driving source is opened on the air damper main body, and the telescopic end of the damper is arranged close to the air damper positioning hole. The closer the telescopic end of the damper is to the rotation axis of the air damper main body, the smaller the telescopic stroke required for the damper.

[0009] Further, the damper includes a hydraulic damper or a pneumatic damper.

[0010] Further, the air damper main body is made of PP-TD40 material.

[0011] Furthermore, the outer surface of the damper body is coated with a TPE layer.

[0012] The beneficial effects of the present utility model are as follows: In the damper structure of the air conditioning system of the present utility model, by installing a damping structure on the air conditioning box housing, a good buffering effect can be achieved when the damper body performs the opening and closing actions, reducing the vibration and noise generated by the impact on the air conditioning box housing during the movement of the damper, improving the stability of the operation of the damper structure, and solving the problems of jitter and noise that may exist during the operation of the damper structure; the present utility model also improves the overall comfort of the air conditioning system, and has a simple structure, is easy to install and maintain.

[0017] As Figure 1 shown, it is the damper structure of the air conditioning system with a damping structure provided in this embodiment, which has an air conditioning box housing 1 and a damper body 2 assembled therein. There is a damper positioning hole 5 on the damper body 2, which is used to cooperate with the drive source and the actuator to realize the deflection action of the damper body 2. Refer to Figure 3 , a damper installation bottom plate 8 is also fixedly installed on the air conditioning box housing 1. A damper pressure plate 4 is installed on the damper installation bottom plate 8 through bolts. The damper pressure plate 4 presses the damper 3 on the damper installation bottom plate 8 to realize the positioning of the damper 3 in the up and down direction. At the same time, a first positioning end 6 and a second positioning end 7 are respectively arranged on the damper installation bottom plate 8 to position both ends of the damper 3 in the length direction. The damper installation bottom plate 8 and the damper pressure plate 4 form a damper installation assembly to realize the stable installation of the damper 3.

[0018] It should be noted that in this embodiment, one damping structure (one damper installation assembly and one damper 3) is used as an example. Refer to Figure 1, the telescopic end of the damper 3 is located on the deflection side of the damper body 2, so that when the damper body 2 deflects back and forth, the side wall of the damper body 2 on the deflection side squeezes or moves away from the telescopic end of the damper 3. Since the damper body 2 will contact the air conditioner case 1 at the last stage of the deflection stroke, certain noise and vibration may be generated. Therefore, the damping structure can be arranged on the deflection side of the damper body 2. When the damper body 2 deflects and contacts and squeezes the telescopic end of the damper 3, it plays a buffering role.

[0019] Specifically, in this embodiment, the telescopic end of the damper 3 is close to the damper positioning hole 5 because the telescopic stroke of the damper 3 is limited. Therefore, a smaller specification of the damper 3 can also achieve the buffering effect. In some other embodiments, the position of the telescopic end of the damper 3 and the telescopic direction of the damper 3 can also be adjusted and changed to a certain extent. In addition, the damper 3 described in this application can be a hydraulic damper or a pneumatic damper, and both can achieve the corresponding effect.

[0020] See Figure 2 , which is a schematic structural diagram of the damper body 2 in this embodiment. The damper body 2 must be made of a durable material. In this embodiment, it is made of the durable material PP-TD40+TPE (encapsulated), which has good airtightness and durability.

[0021] 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.
