[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-3 This embodiment provides an automotive air conditioning damper structure 100, which includes a damper body 110 and a damper shaft 120 connected to the damper body 110. The damper shaft 120 is rotatably connected to the housing 210 of the automotive air conditioning unit 200, and at least one end of the damper shaft 120 is provided with a connecting spline 121, which is used for transmission connection with the drive structure.

[0025] Please refer to Figures 1-3 The working principle of the car air conditioning damper structure 100 is as follows: The automotive air conditioning damper structure 100 includes a damper body 110 and a damper shaft 120 connected to the damper body 110. The damper shaft 120 is rotatably connected to the housing 210 of the automotive air conditioning unit 200, and at least one end of the damper shaft 120 is provided with a connecting spline 121 for transmission connection with the drive structure. Therefore, the automotive air conditioning damper structure 100 uses a connecting spline 121 to achieve the transmission connection between the damper and the drive structure. By setting the connecting spline 121, the stability of the transmission can be improved, and the wear at the transmission connection can be reduced. Under this condition, the precision of the connection fit can be improved, which helps to reduce or eliminate looseness at the damper shaft, thereby avoiding the situation where the damper is not closed properly, and thus reducing the probability of damper misalignment and abnormal noise.

[0026] Further, please refer to Figures 1-3 In this embodiment, the connecting spline 121 is a T-type connecting spline. However, in other embodiments of this invention, the configuration of the connecting spline 121 can be adjusted to other spline structures, such as a cross-shaped spline, depending on the actual situation.

[0027] Based on the above structure, please refer to Figures 1-7 In this embodiment, the damper body 110 in the secondary air conditioning damper structure may include a damper plate 111 and a damper sleeve 112. The damper plate 111 is connected to the damper shaft 120, and the damper sleeve 112 is connected to the damper shaft 120 and is sleeved on the outer edge of the damper plate 111.

[0028] This design makes the damper body 110 a modular structure. The damper sleeve 112 improves the sealing at the contact point between the damper and the air conditioning unit during use, thus extending the service life of the damper body 110. Furthermore, since the damper sleeve 112 is fitted onto the damper plate 111, wear on the sleeve can be easily replaced, reducing maintenance and operating costs of the automotive air conditioning damper structure 100. In addition, based on the aforementioned damper body 110 structure, different structural materials can be used to manufacture the damper plate 111 and damper sleeve 112 to meet various usage requirements.

[0029] In this embodiment, when configuring the damper sleeve 112, the damper sleeve 112 includes a sleeve portion 113 and two spaced-apart connecting portions 114. The sleeve portion 113 is sleeved on the damper plate 111, and both connecting portions 114 are connected to the damper shaft 120. That is, the sleeve portion 113 is arranged along the outer edge of the damper plate 111. By connecting the sleeve portion 113 to the connecting portions 114, and connecting the connecting portions 114 to the damper shaft 120, the assembly of the damper body 110 and its connection to the damper shaft 120 are realized. Moreover, this structural arrangement simplifies the structure of the automotive air conditioning damper structure 100 and simplifies its installation steps, thereby helping to reduce its manufacturing and usage costs.

[0030] As described above, the damper shaft 120 is connected to the damper plate 111 and then to the connecting part 114 on the damper sleeve 112. To ensure proper mating between the damper shaft 120 and the connecting part 114 of the damper sleeve 112, positioning parts 122 are provided at both ends of the damper shaft 120. Each of the two connecting parts 114 is connected to one of the two positioning parts 122. Specifically, the positioning part 122 includes multiple positioning grooves 123, and the connecting part 114 includes multiple positioning protrusions 115. The multiple positioning grooves 123 and the multiple positioning protrusions 115 cooperate one-to-one, thereby improving the connection stability between the damper sleeve 112 and the damper shaft 120.

[0031] Furthermore, after the damper sleeve 112 is connected to the damper shaft 120, in order to restrict its movement equivalent to the damper shaft 120, annular limiting platforms 124 are provided at both ends of the positioning part 122 along the axial direction of the damper shaft 120; the connecting part 114 is located between the two annular limiting platforms 124, so that the movement of the connecting part 114 can be restricted by the annular limiting platforms 124 to maintain its installation stability.

[0032] Further, please refer to Figures 1-7Based on the above structure, it can be seen that the positioning protrusion 115 on the connecting part 114 and the positioning groove 123 of the positioning part 122 correspond to each other and cooperate. Based on the aforementioned structure of the annular limiting platform 124, the connection stability can be improved. On this basis, an annular cover 116 is arranged on the outside of the damper sleeve 112. The annular cover 116 covers the annular limiting platform 124. Through this arrangement, the annular cover 116 is located on the outer periphery of the annular limiting platform 124. Moreover, the annular cover 116 can be used to cover the rotating connection between the damper shaft 120 and the automotive air conditioning box 200 from the inside of the automotive air conditioning box 200, thereby improving the sealing of the rotating connection.

[0033] In order to improve the connection stability between the damper sleeve 112 and the damper plate 111, the automotive air conditioning damper structure 100 also includes a support strip 130 connected to the damper sleeve 112. Along the axial direction of the damper shaft 120, the support strip 130 is located in the middle of the damper sleeve 112 and abuts against the damper plate 111.

[0034] Based on the above-described automotive air conditioning damper structure 100, please refer to... Figures 1-9 This embodiment also provides an automotive air conditioning unit 200, which includes a housing 210 and the aforementioned automotive air conditioning damper structure 100; the damper shaft 120 of the automotive air conditioning damper structure 100 is rotatably connected to the housing 210. This automotive air conditioning unit 200 adopts the aforementioned automotive air conditioning damper structure 100, and therefore possesses all the advantages of the aforementioned automotive air conditioning damper structure 100, which will not be elaborated further here.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
