[0026] In order to make the purpose, technical scheme and beneficial effects of the utility model clearer and more apparent, the technical scheme of the utility model is further explained below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.

[0027] Referring to Figures 1 to 5 The utility model provides a kind of installation structure of air door panel 3, it is applied to air conditioner 1, the air conditioner 1 is equipped with air outlet 2, the installation structure includes:

[0028] Air door panel 3, it is movably arranged in the air outlet 2, and it has the spacing limit hole 4 and pivot hole 5 being arranged;

[0029] Connecting piece, including connecting block 6 and spacing limit shaft 7 and pivot 8 being arranged in the connecting block 6, the limit shaft 7 and the pivot 8 are respectively inserted in the limit hole 4 and the pivot hole 5;

[0030] Stepping motor 10, it is arranged in the connecting block 6, for driving the pivot 8 in the pivot hole 5 revolves, and makes the limit shaft 7 linkage air door panel 3 revolves around the pivot 8 via the connecting block 6, for opening or closing the air outlet 2.

[0031] In this embodiment, the damper panel 3 is provided with limiting holes 4 and rotating shaft holes 5, and connecting pieces, including connecting blocks 6, limiting shafts 7 and rotating shafts 8, are arranged on the damper panel 3. The limiting shafts 7 and the rotating shafts 8 are arranged one by one corresponding to the limiting holes 4 and the rotating shaft holes 5, and are used to install the damper panel 3 at the air outlet 2 of the air conditioner 1. It can be understood that, in order to stably install the damper panel 3, corresponding limiting holes 4, rotating shaft holes 5 and connecting pieces connected with the air conditioner 1 are arranged at the upper and lower ends of the damper panel 3. In order to drive the damper panel 3 to open or close the air outlet 2, a stepping motor 10 is arranged on the connecting block 6, which is used to drive the rotating shaft 8 to rotate in the rotating shaft hole 5. The driving shaft of the stepping motor 10 is connected with the connecting block 6 (a groove can be arranged on the connecting block 6 for inserting the driving shaft of the stepping motor 10), and the rotating shaft 8 is movably connected with the air conditioner 1. Then, the limiting shaft 7 is inserted into the limiting hole 4 of the damper panel 3, and the limiting shaft 7 is arranged in cooperation with the rotating shaft 8, which has the effect of amplifying the radius of the cooperation surface of the torque transmission. The greater the distance between the rotating shaft 8 and the limiting shaft 7, the greater the equivalent radius of the rotating shaft 8. In the case of the same cooperation gap, the shaking angle between the rotating cooperation surfaces caused by the cooperation gap is smaller, and the local stress of the rotating shaft 8 is reduced. When the stepping motor 10 drives the rotating shaft 8 to rotate through the connecting block 6, the limiting shaft 7 drives the damper panel 3 to revolve around the rotating shaft 8 at the same time, so as to realize the opening or closing operation of the air outlet 2. Without increasing the structure size of the damper rotating shaft 8, the size of the cooperation surface of the torque transmission is extended through the cooperation mode of the limiting shaft 7 and the rotating shaft 8, and the occupied space is basically not increased. Without increasing the size of the damper panel 3, the total volume of the parts is increased less, and the cost is increased less.

[0032] The rotating shaft 8 is provided with a connecting hole 9, and the connecting hole 9 is inserted into the air conditioner 1.

[0033] In this embodiment, the driving shaft of the stepping motor 10 is connected with the connecting block 6, and the connecting hole 9 of the connecting block 6 is inserted into the air conditioner 1, which can ensure that a stable and reliable mechanical connection is formed between the stepping motor 10 and the connecting block 6, so that the rotating force can be more efficiently and accurately transmitted to the damper panel 3, and the accuracy and consistency of the movement of the damper panel 3 are ensured.

[0034] The connecting hole 9 and the rotating shaft hole 5 are coaxially arranged.

[0035] In this embodiment, the rotating shaft hole 5 and the connecting hole 9 on the connecting block 6 are coaxially arranged, which reduces the complexity caused by different shafts, ensures the directness and consistency of force transmission, reduces the error caused by eccentricity or misalignment, and improves the accuracy and stability of the rotation of the damper panel 3.

[0036] The limiting hole 4 and the rotating shaft hole 5 are square in cross section. Further, the limiting shaft 7 and the rotating shaft 8 are square in cross section.

[0037] In this embodiment, the square cross-section design can effectively prevent the rotation misplacement of the limiting shaft 7 and the rotating shaft 8 in the corresponding holes. The traditional circular cross-section may cause the sliding or unstable rotation between the components, while the square cross-section provides additional locking function to ensure the correct relative position of the components, and the square cross-section provides tighter fit, so that the torque can be more efficiently transmitted to the damper panel 3 when the stepping motor 10 drives the rotating shaft 8, reducing energy loss and improving response speed and accuracy; the square cross-section increases the contact area, which helps to evenly distribute the stress and reduce the risk of local wear and deformation.

[0038] The connecting block 6 is provided with a plurality of first reinforcing ribs 11.

[0039] In this embodiment, a plurality of first reinforcing ribs 11 are added to the connecting block 6 to enhance the structural strength and stability of the connecting block 6, so that the connecting block 6 is not easily deformed or damaged when driven by the stepping motor 10.

[0040] The damper panel 3 is provided with a plurality of second reinforcing ribs 12.

[0041] In this embodiment, the reinforcing ribs can significantly increase the overall rigidity and bending resistance of the damper panel 3, so that it is not easily deformed or damaged when subjected to external force, thereby maintaining the shape stability of the damper panel 3 and the reliability of long-term use. The damper panel 3 will be frequently opened and closed during the operation of the air conditioner, which will exert repeated mechanical stress on the damper panel 3. The second reinforcing ribs 12 can effectively disperse these stresses and reduce the possibility of fatigue damage, thereby prolonging the service life of the damper panel 3.

[0042] The plurality of second reinforcing ribs 12 are distributed in the form of an umbrella on the damper panel 3.

[0043] In this embodiment, the umbrella-shaped second reinforcing ribs 12 can effectively disperse the driving force of the stepping motor 10 evenly to the entire damper panel 3, avoiding stress concentration in a certain point or area, which helps to reduce the risk of local deformation and fatigue damage, thereby prolonging the service life of the damper panel 3, and increasing the overall rigidity and bending resistance of the damper panel 3, making it more stable when subjected to external pressure. Especially in the case of frequent opening and closing of the damper panel 3, this can effectively prevent the damper panel 3 from warping or deforming.

[0044] The embodiment also provides an air conditioner 1 comprising the mounting structure of the damper panel 3 described above. The specific structure of the air conditioner 1 is referred to the above embodiments. Since the air conditioner 1 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0045] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application.
