A slot is provided on each of the two planes. A shaft hole is provided on the actuating element, and a latch is provided on the plane of the shaft hole. When the end of the rotating shaft engages with the actuating element, the latch extends into the slot. This automotive air conditioning damper assembly provides a double-sided snap-fit ​​connection between the symmetrical fan blades and the rotating shaft, completely avoiding air conditioning mode failure caused by misalignment of the damper and rotating shaft, greatly improving the product qualification rate. It not only has excellent stability and flexibility but also prevents the rotating shaft and the actuating element from jamming together, and prevents axial movement during use.

[0004] However, the following problems still exist: During actual use, with the continuous output of air volume, various kinds of dust will inevitably accumulate on the components at the damper plate. Long-term use can easily cause adverse effects on the damper components, which may reduce their service life. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an automotive air conditioning damper assembly. By optimizing the ventilation component structure at the damper plate, the overall air delivery effect of the damper assembly is improved, enhancing air delivery quality while also providing effective protection for the components.

[0006] This utility model is achieved through the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0023] An automotive air conditioning damper assembly includes a damper plate 1. The damper plate 1 includes a base plate 101, an outer skin layer 102, a pad 103, a pressure-resistant layer 104, and reinforcing members 105. The outer skin layer 102 is sleeved on the outside of the base plate 101. The pad 103 is laid between the base plate 101 and the outer skin layer 102. The pressure-resistant layer 104 is laid on one side of the pad 103. Reinforcing members 105 are evenly arranged sequentially between the pressure-resistant layer 104 and the outer skin layer 102. The outer skin layer 102 is an integrated structure made of PVC material, the pad 103 is made of steel sheet material, the pressure-resistant layer 104 is made of silicone material and bonded together, and the reinforcing members 105 are an integrated structure made of steel structural material. The overall structure of the damper plate 1 is safer and more stable, significantly improving the overall pressure and impact resistance, thereby ensuring the safety of the overall structure.

[0024] The surface of the damper plate 1 is covered with a mesh screen 2, and ventilation pipes 3 are sequentially inserted through the surface of the damper plate 1. The end of the ventilation pipe 3 has a semi-circular through hole, and a cover plate is hinged to the surface of the ventilation pipe 3 at the through hole. This structure allows the ventilation pipe 3 to be adjusted as needed, and the mesh screen 2 can be removed and the cover plate closed as needed.

[0025] The bottom surface of the damper plate 1 is bolted with an installation edge 5. An air supply duct 4 is integrally formed on one side of the installation edge 5. The air supply duct 4 is connected to the ventilation pipe 3. An internal pipe 6 is slidably inserted into the air supply duct 4. An air supply component is provided on the inner wall of the air supply duct 4.

[0026] The inner wall of the air supply duct 4 is uniformly provided with pads 41. The pads 41 are integral structures made of rubber material, and the surface of the pads 41 is in contact with the surface of the built-in duct 6. The pad structure 41 is set to allow the air supply duct 4 to be better assembled with the built-in duct 6, so that it can rotate to a certain extent while also achieving a certain friction effect, ensuring the stability of the built-in duct 6, making the overall structure more stable and safer, and enabling the built-in duct 6 to achieve a better air supply function more conveniently in actual use.

[0027] The air supply assembly includes a drive shaft 8, a roller 9, a turntable 10, and air supply blades 11. The drive shaft 8 is movably mounted to the inner wall of the air supply duct 4 via bearings. The turntable 10 is keyed to the surface of the drive shaft 8. The air supply blades 11 are integrally formed uniformly on the surface of the turntable 10. The surface of the air supply blades 11 has an integrally formed arc-shaped groove, and a filter is installed in the groove of the air supply blades 11.

[0028] A roller 9 is keyed to one side of the drive shaft 8. One side of the roller 9 has an integrally formed bevel, and the top surface of the built-in duct 6 has an integrally formed protruding edge 7, which contacts the bevel of the roller 9. The built-in duct 6 can rotate and adjust inside the air supply duct 4 as needed. During rotation, the protruding edge 7 cooperates with the roller 9 to make the entire movement more stable. Furthermore, by adjusting the rotation of the built-in duct 6, the air delivery vanes 11 can deliver air to various parts of the inner wall of the built-in duct 6 while assisting in air delivery, increasing the airflow in the area where the air delivery vanes 11 are located. This helps to remove dust from the corresponding inner wall of the built-in duct 6, preventing dust from accumulating over time and causing agglomeration. During operation, as air continues to flow from the air supply duct 4, each air delivery vane 11 rotates with the roller 9 due to the wind force, further filtering out any dust that may be present in the air duct, thereby improving the air quality.
