[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0043] The wind guide louver 10 according to an embodiment of the first aspect of the utility model is described below with reference to the accompanying drawings.

[0044] like Figures 1 to 6 As shown, the wind guide louver 10 according to the embodiment of the first aspect of the utility model includes: a blade 1 and a rotating shaft 2, the rotating shaft 2 is connected to the blade 1, and the wind guide louver 10 can be installed through the rotating shaft 2, such as inserting the rotating shaft 2 into the mounting hole 5 at the mounting position of the air guide louver 10, and the rotation of the rotating shaft 2 in the mounting hole 5 can realize the swing of the blade 1 to adjust the gas flow direction.

[0045] The rotating shaft 2 includes a first shaft section 21 and a second shaft section 22, wherein the first shaft section 21 is connected to the blade 1, and the second shaft section 22 is connected to an end of the first shaft section 21 away from the blade 1, and the structural strength of the first shaft section 21 is greater than the structural strength of the second shaft section 22. That is, the second shaft section 22 is connected to the blade 1 through the first shaft section 21, that is, in the axial direction of the rotating shaft 2, the first shaft section 21 is connected between the blade 1 and the second shaft section 22, wherein the first shaft section 21 has a higher structural strength than the second shaft section 22, which can better improve the anti-deformation ability of the first shaft section 21, therefore, during the installation and rotation of the wind guide louver 10, the deformation and fracture of the first shaft section 21 when subjected to force can be better avoided, and at the same time, the connection between the rotating shaft 2 and the blade 1 through the first shaft section 21 can better improve the connection strength between the rotating shaft 2 and the blade 1, thereby avoiding the fracture at the connection position between the rotating shaft 2 and the blade 1, which is beneficial to improving the overall structural stability of the wind guide louver 10 to extend the service life of the wind guide louver 10.

[0046] According to the wind guide louver 10 of the first aspect embodiment of the utility model, the rotating shaft 2 includes a first shaft segment 21 and a second shaft segment 22. The first shaft segment 21 is connected to the blade 1, and the second shaft segment 22 is connected to the end of the first shaft segment 21 away from the blade 1. The structural strength of the first shaft segment 21 is greater than the structural strength of the second shaft segment 22, which can better improve the deformation resistance of the first shaft segment 21 to avoid deformation and fracture of the first shaft segment 21 when the force is applied. At the same time, the rotating shaft 2 is connected to the blade 1 through the first shaft segment 21, which can better improve the connection strength between the rotating shaft 2 and the blade 1, thereby avoiding fracture at the connection position between the rotating shaft 2 and the blade 1, which is beneficial to improving the overall structural stability of the wind guide louver 10 to extend the service life of the wind guide louver 10.

[0047] According to some embodiments of the utility model, the projection of the first shaft segment 21 on the reference plane is in the shape of a circular ring, and the reference plane is perpendicular to the axial direction of the rotating shaft 2, that is, the first shaft segment 21 forms a hollow cavity 212 in the middle of the radial direction. Therefore, by providing the hollow cavity 212 on the first shaft segment 21, the weight of the first shaft segment 21 can be reduced, thereby reducing the weight of the air guide louver 10 and reducing the production cost. In addition, when the air guide louver 10 is produced by injection molding or the like, the hollow cavity 212 formed can better prevent shrinkage defects generated during the production process of the air guide louver 10, thereby improving the yield rate of the production of the air guide louver 10.

[0048] Among them, the second shaft segment 22 includes a plurality of elastic connecting arms 222 connected to the first shaft segment 21, and the wall thickness of the first shaft segment 21 is greater than the thickness of the elastic connecting arms 222 in the radial direction of the rotating shaft 2. Among them, it can be understood that the greater the thickness, the higher the structural strength. In other words, the first shaft segment 21 has a higher structural strength than the elastic connecting arms 222. In this way, the structural strength of the first shaft segment 21 can be better guaranteed, and the connection strength between the first shaft segment 21 and the blade 1 can be improved, thereby avoiding the first shaft segment 21 and the connection position between the rotating shaft 2 and the blade 1 from breaking, which is beneficial to improving the overall structural stability of the wind guide louver 10 to extend the service life of the wind guide louver 10.

[0049] According to some embodiments of the utility model, the hollow portion of the first shaft segment 21 is cylindrical and extends along the axial direction of the rotating shaft 2 and is coaxially arranged with the rotating shaft 2. In other words, the central axis of the cylinder formed by the hollow cavity 212 of the first shaft segment 21 is in the same straight line as the central axis of the rotating shaft 2. As a result, the first shaft segment 21 has a uniform wall thickness, thereby reducing shrinkage defects caused by uneven wall thickness during the injection molding process, which is conducive to improving the yield rate of the air guide louver 10 during production.

[0050] According to some embodiments of the present invention, the ratio of the wall thickness of the first shaft segment 21 to the radius of the first shaft segment 21 is in the range of 1 / 4-1 / 6. That is, the wall thickness of the first shaft segment 21 is controlled within the range of 1 / 4 to 1 / 6 of the radius of the first shaft segment 21. For example, the wall thickness of the first shaft segment 21 can be 1 / 4, 5 / 21, 2 / 9, 1 / 5, 2 / 11, 5 / 34, 1 / 6, etc. of the radius of the first shaft segment 21, and no specific restrictions are made here. Wherein, when the radius of the first shaft segment 21 remains unchanged, the greater the ratio of the wall thickness of the first shaft segment 21 to the radius of the first shaft segment 21, the thicker the wall thickness of the first shaft segment 21, the closer the first shaft segment 21 is to a solid structure, and the higher the structural strength is, but the risk of shrinkage defects is also increased. On the contrary, the smaller the ratio of the wall thickness of the first shaft segment 21 to the radius of the first shaft segment 21, the thinner the wall thickness of the first shaft segment 21, the weaker the structural strength is, but the risk of shrinkage defects is also reduced. Therefore, by controlling the wall thickness of the first shaft segment 21 within the range of 1 / 4 to 1 / 6 of the radius of the first shaft segment 21, it is possible to avoid the structural strength of the first shaft segment 21 being weakened due to the wall thickness of the first shaft segment 21 being too thin, and at the same time, it is possible to avoid shrinkage defects caused by the wall thickness of the first shaft segment 21 being too thick, thereby ensuring the structural strength of the first shaft segment 21 while preventing shrinkage defects from occurring during the injection molding process.

[0051] According to some embodiments of the utility model, the first shaft section 21 is a solid cylinder. Among them, the solid structure has a higher deformation resistance. Therefore, the structural strength of the first shaft section 21 can be further improved, making it less likely to break, and at the same time, the connection area between the first shaft section 21 and the blade 1 can be increased, thereby further improving the connection strength between the rotating shaft 2 and the blade 1 to prevent the connection position between the rotating shaft 2 and the blade 1 from breaking. In addition, the structure of the first shaft section 21 with a solid structure is also simpler, which is convenient for production and molding.

[0052] According to some embodiments of the utility model, the wind guide louver 10 further includes a limiting portion 3, the limiting portion 3 is connected between the blade 1 and the rotating shaft 2, the limiting portion 3 protrudes from the outer peripheral surface of the first shaft segment 21, the second shaft segment 22 includes a plurality of elastic connecting arms 222 arranged at intervals on the first shaft segment 21, and a limiting protrusion 4 is provided at one end of the elastic connecting arm 222 away from the first shaft segment 21, and the limiting protrusion 4 protrudes from the outer side surface of the elastic connecting arm 222 in the radial direction of the rotating shaft 2. In other words, the elastic connecting arm 222 and the limiting protrusion 4 can form an elastic buckle, that is, a plurality of elastic buckles are provided at one end of the first shaft segment 21 away from the blade 1, and the difficulty of installing the rotating shaft 2 can be well reduced by using a plurality of elastic buckles. Moreover, in the axial direction of the rotating shaft 2, the limiting portion 3 and the limiting protrusion 4 can better clamp and fix the part between the two opposite sides. For example, when the rotating shaft 2 is inserted into the mounting hole 5, the limiting portion 3 and the limiting protrusion 4 respectively abut against the outer peripheral edges of the mounting hole 5 at both ends of the axial direction of the rotating shaft 2. Therefore, through the cooperation of the limiting portion 3 and the limiting protrusion 4, the axial freedom of movement of the rotating shaft 2 can be better limited, which is beneficial to improving the stability of the air guide louver 10 after installation.

[0053] The following describes an air guide assembly 100 according to an embodiment of the second aspect of the utility model with reference to the accompanying drawings.

[0054] like Figure 1-Figure 12 As shown, the air guide assembly 100 according to the second embodiment of the utility model comprises: a mounting plate 20 and an air guide louver 10, a mounting hole 5 is formed on the mounting plate 20, and a rotating shaft 2 is passed through the mounting hole 5. That is, the air guide louver 10 is fixedly mounted on the mounting plate 20 by assembling the rotating shaft 2 and the mounting hole 5, and the rotating shaft 2 can rotate around the central axis of the rotating shaft 2 in the mounting hole 5, so as to realize the swing of the air guide louver 10 to adjust the direction of the air flow.

[0055] According to the wind guide assembly 100 of the second aspect of the embodiment of the utility model, the deformation resistance of the first shaft segment 21 can be better improved to avoid deformation and fracture of the first shaft segment 21 when the force is applied. At the same time, the connection between the rotating shaft 2 and the blade 1 through the first shaft segment 21 can better improve the connection strength between the rotating shaft 2 and the blade 1, thereby avoiding fracture at the connection position between the rotating shaft 2 and the blade 1, which is beneficial to improving the overall structural stability of the wind guide louver 10 to extend the service life of the wind guide louver 10.

[0056] According to some embodiments of the utility model, the minimum distance between the outer circumference of the first shaft segment 21 and the inner circumference of the mounting hole 5 is the first distance, the minimum distance between the outer circumference of the second shaft segment 22 and the inner circumference of the mounting hole 5 is the second distance, and the first distance is smaller than the second distance.

[0057] That is to say, the minimum distance between the outer circumference of the second shaft segment 22 and the inner circumference of the mounting hole 5 is greater than the minimum distance between the outer circumference of the first shaft segment 21 and the inner circumference of the mounting hole 5. Therefore, when the air guide plate rotates relative to the mounting plate 20 so that the rotating shaft 2 rotates in the mounting hole 5, the outer circumference of the second shaft segment 22 can maintain a minimum distance greater than zero with the inner circumference of the mounting hole 5 when the outer circumference of the first shaft segment 21 contacts the inner circumference of the mounting hole 5, that is, the outer circumference of the second shaft segment 22 can be prevented from contacting the inner circumference of the mounting hole 5. In other words, the relatively weak structural strength of the rotating shaft 2 can be prevented from contacting the inner circumference of the mounting hole 5, thereby preventing the second shaft segment 22 from being fatigued or fractured due to the contact with the inner circumference of the mounting hole 5 during the rotation of the shaft segment 22 in the mounting hole 5. In addition, the first shaft segment 21 has a higher structural strength than the second shaft segment 22, which can reduce the risk of fracture of the first shaft segment 21 when the outer circumference contacts the inner circumference of the mounting hole 5 when the first shaft segment 21 rotates in the mounting hole 5. In this way, the risk of the rotating shaft 2 breaking due to force during rotation can be reduced, which is beneficial to extending the service life of the air guide louver 10.

[0058] In some embodiments, a guide surface 53 is formed at one end of the mounting hole 5 adjacent to the blade 1, and the guide surface 53 extends obliquely toward the outer peripheral side of the mounting hole 5 in the direction from the rotating shaft 2 to the blade 1. Therefore, during the installation process of the air guide louver 10, the position deviation of the rotating shaft 2 when inserted into the mounting hole 5 can be well corrected by the guide surface 53, that is, the rotating shaft 2 can be well guided into the installation space by the guide surface 53, so there is no need to completely align the rotating shaft 2 with the mounting hole 5 before inserting it, thereby reducing the difficulty of positioning the rotating shaft 2 when inserting it into the mounting hole 5, and further reducing the difficulty of assembling the air guide louver 10 and the mounting plate 20, which is conducive to improving the assembly efficiency of the air guide assembly 100.

[0059] In some embodiments, the inner diameter of the mounting hole 5 gradually decreases in the direction from the blade 1 to the rotating shaft 2, that is, in the axial direction of the rotating shaft 2, the inner diameter of the end of the mounting hole 5 adjacent to the blade 1 is larger than the inner diameter of the end of the mounting hole 5 away from the blade 1. Thus, the rotating shaft 2 is easily inserted, and at the same time, the inner circumferential surface of the mounting hole 5 can form an inclined support for the rotating shaft 2, which is conducive to improving the connection stability between the air guide louver 10 and the mounting plate 20.

[0060] According to some embodiments of the utility model, the first spacing is 0, and the second spacing is greater than 0. That is to say, the minimum spacing between the outer circumference of the first shaft segment 21 and the inner circumference of the mounting hole 5 is 0, that is, the first shaft segment 21 at least has a portion where the outer circumference contacts the inner circumference of the mounting hole 5. Therefore, through the contact between the outer circumference of the first shaft segment 21 and the inner circumference of the mounting hole 5, the fixing effect of the mounting hole 5 on the rotating shaft 2 can be better improved, so that the rotating shaft 2 can be better prevented from shaking in the mounting hole 5, so as to improve the stability of the air guide louver 10 after installation. In addition, the minimum spacing between the outer circumference of the second shaft segment 22 and the inner circumference of the mounting hole 5 is not 0, that is, the outer circumference of the second shaft segment 22 is spaced from the inner circumference of the mounting hole 5, which can better avoid the breakage caused by the contact force between the second shaft segment 22 and the inner circumference of the mounting hole 5 when the rotating shaft 2 rotates, which is conducive to extending the service life of the air guide louver 10.

[0061] According to some embodiments of the utility model, a first protrusion 211 is formed on the outer circumferential surface of the first shaft segment 21, and the first spacing is the minimum spacing between the first protrusion 211 and the inner circumferential surface of the mounting hole 5; a second protrusion 221 is formed on the outer circumferential surface of the second shaft segment 22, and the second spacing is the minimum spacing between the second protrusion 221 and the inner circumferential surface of the mounting hole 5. That is to say, the minimum distance between the first protrusion 211 and the inner circumference of the mounting hole 5 is smaller than the minimum distance between the second protrusion 221 and the inner circumference of the mounting hole 5. Therefore, when the rotating shaft 2 rotates in the mounting hole 5, the second protrusion 221 can maintain a distance greater than zero from the inner circumference of the mounting hole 5 when the first protrusion 211 contacts the inner circumference of the mounting hole 5. That is, the second protrusion 221 can be prevented from contacting the inner circumference of the mounting hole 5 during the rotation of the rotating shaft 2, thereby preventing the force of the rotating shaft 2 from being transmitted to the second shaft segment 22 through the second protrusion 221, and further avoiding the risk of the second shaft segment 22 being broken due to the force, which is beneficial to extending the service life of the air guide louver 10.

[0062] According to some embodiments of the present invention, the mounting plate 20 includes a plate body 6 and an elastic deformation portion 7, the plate body 6 having a first side and a second side opposite to each other, the blade 1 is located on the first side, the elastic deformation portion 7 is located on the second side and is a plurality of the plate body 6 arranged at intervals in the circumferential direction of the rotating shaft 2, a first hole segment 51 is formed on the plate body 6, the outer peripheral contour of the projection of the first hole segment 51 on the reference surface is a closed ring, a second hole segment 52 is jointly defined by the plurality of elastic deformation portions 7, and the first hole segment 51 and the second hole segment 52 jointly constitute a mounting hole 5. That is to say, in the direction away from the blade 1, the mounting hole 5 includes a first hole segment 51 and a second hole segment 52 which are connected in sequence, the first hole segment 51 is formed in the plate body 6 and is formed as a closed hole in the circumferential direction of the rotating shaft 2, and the second hole segment 52 is located between multiple elastic deformation parts 7, wherein the elastic deformation part 7 can produce a certain degree of elastic deformation. Therefore, when the rotating shaft 2 is inserted into the second hole segment 52, the elastic deformation part 7 can be pushed by the rotating shaft 2 to elastically deform along the radial direction of the rotating shaft 2 toward the direction away from the central axis of the rotating shaft 2, so as to reduce the extrusion of the inner circumference of the mounting plate 20 on the rotating shaft 2, thereby reducing the difficulty of inserting the rotating shaft 2 into the mounting hole 5 and reducing the extrusion damage to the rotating shaft 2, which is beneficial to improving the assembly efficiency and structural stability of the air guide louver 10.

[0063] In some embodiments, a plurality of contact protrusions are formed on the outer circumference of the rotating shaft 2 and arranged at intervals in the up-down direction, and the contact protrusions are in contact with the inner circumference of the mounting hole 5, that is, the rotating shaft 2 contacts the inner circumference of the mounting hole 5 through the plurality of contact protrusions, which can effectively reduce the contact area between the rotating shaft 2 and the inner circumference of the mounting hole 5, thereby reducing the resistance between the rotating shaft 2 and the inner circumference of the mounting hole 5 when the rotating shaft 2 rotates relative to the mounting plate 20, which is conducive to reducing the demand for driving force for the rotation of the air guide louver 10. In a specific example, the contact protrusion located at the first shaft segment 21 is the first protrusion 211, and the contact protrusion located at the second shaft segment 22 is the second protrusion 221.

[0064] According to some embodiments of the utility model, the connection position between the first shaft segment 21 and the second shaft segment 22 is located in the second hole segment 52. That is to say, one end of the first shaft segment 21 connected to the second shaft segment 22 is inserted into the second hole segment 52, and the second shaft segment 22 and the first hole segment 51 are arranged at intervals along the axial direction of the rotating shaft 2. In this way, the outer circumference of the second shaft segment 22 can be better avoided from contacting the inner circumference of the first hole segment 51. The first shaft segment 21 serves as the main force position between the first hole segment 51 when the rotating shaft 2 rotates, which can reduce the risk of the second shaft segment 22 being broken due to the force acting on the second shaft segment 22 during the rotation of the rotating shaft 2, which is beneficial to improving the overall structural stability of the wind guide louver 10 to extend the service life of the wind guide louver 10.

[0065] According to some embodiments of the utility model, in the axial direction of the rotating shaft 2, the distance between the connection position of the first shaft segment 21 and the second shaft segment 22 and the first hole segment 51 is in the range of 0.5mm-1.5mm. That is to say, in the axial direction of the rotating shaft 2, the depth of the end of the first shaft segment 21 close to the second shaft segment 22 inserted into the second hole segment 52 is controlled to be in the range of 0.5mm to 1.5mm. For example, the depth of the end of the first shaft segment 21 close to the second shaft segment 22 inserted into the second hole segment 52 can be 0.5mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.3mm, 1.5mm, etc., and no specific limitation is made here. Among them, the deeper the depth of the end of the first shaft segment 21 close to the second shaft segment 22 inserted into the second hole segment 52, the larger the axial distance between the second shaft segment 22 and the first hole segment 51 in the rotating shaft 2, and the lower the risk of the second shaft segment 22 contacting the inner circumferential wall of the first hole segment 51 and causing fracture, but the larger the space occupied by the first shaft segment 21 in the second hole segment 52; conversely, the shallower the depth of the end of the first shaft segment 21 close to the second shaft segment 22 inserted into the second hole segment 52, the smaller the axial distance between the second shaft segment 22 and the first hole segment 51 in the rotating shaft 2, and the higher the risk of the second shaft segment 22 contacting the inner circumferential wall of the first hole segment 51 and causing fracture, but the larger the space occupied by the first shaft segment 21 in the second hole segment 52.

[0066] Therefore, the depth of the end of the first shaft segment 21 close to the second shaft segment 22 inserted into the second hole segment 52 is controlled within the range of 0.5 mm to 1.5 mm, which can reduce the risk of breakage caused by contact between the second shaft segment 22 and the inner circumferential wall of the first hole segment 51 while reducing the space occupied by the first shaft segment 21 in the second hole segment 52, and the layout is reasonable.

[0067] In some embodiments, the limiting portion 3 abuts against the side surface of the plate body 6 facing the first side along the axial direction of the rotating shaft 2, and the limiting protrusion 4 abuts against the side surface of the elastic connection portion away from the plate body 6. That is to say, in the axial direction of the rotating shaft 2, the limiting portion 3 abuts against the side surface of the plate body 6 facing the first side, so that the rotating shaft 2 can be better prevented from moving toward the second side, and the limiting protrusion 4 abuts against the side surface of the elastic deformation portion 7 away from the plate body 6, so that the rotating shaft 2 can be better prevented from moving toward the first side, so that the cooperation between the limiting portion 3 and the limiting protrusion 4 can better limit the freedom of movement of the rotating shaft 2 in the axial direction of the mounting hole 5, so as to ensure that the rotating shaft 2 is stably inserted into the mounting hole 5.

[0068] Specifically, in the process of assembling the air guide louver 10 into the mounting hole 5, the rotating shaft 2 is aligned with the mounting hole 5 and inserted. When multiple elastic buckles are inserted into the first hole section 51, the limiting protrusion 4 is pushed by the inner circumferential wall of the first hole section 51 to drive the elastic connecting arm 222 to swing toward the direction close to the central axis of the mounting hole 5. After the limiting protrusion 4 enters the second hole section 52, the limiting protrusion 4 can push the elastic deformation part 7 to swing toward the direction away from the central axis of the mounting hole 5 to reduce the amplitude of the extrusion deformation of the elastic connecting arm 222 until the limiting protrusion 4 moves to the side of the elastic deformation part 7 away from the plate body 6. At this time, the elastic connecting arm 222 and the elastic deformation part 7 resume deformation, so that the limiting protrusion 4 is stuck on the side of the elastic deformation part 7 away from the plate body 6, thereby preventing the rotating shaft 2 from escaping from the mounting hole 5.

[0069] According to some embodiments of the utility model, a receiving groove 8 is formed on the side of the plate body 6 facing the first side, the mounting hole 5 is formed on the inner bottom wall of the receiving groove 8, the inner diameter of the receiving groove 8 is larger than the inner diameter of the mounting hole 5, and the limiting portion 3 is located in the receiving groove 8. Therefore, the limiting portion 3 can be better accommodated by the receiving groove 8, that is, the limiting portion 3 can be better prevented from protruding from the side of the plate body 6 facing the first side. Therefore, the limiting portion 3 protruding from the side of the plate body 6 facing the first side can be better prevented from blocking the gas, so that the air volume loss when the airflow flows through the mounting plate 20 can be better reduced.

[0070] In some embodiments, the outer circumference of the limiting portion 3 is spaced from the inner circumference of the receiving groove 8, so as to avoid the rotation resistance caused by the contact between the limiting portion 3 and the inner circumference of the receiving groove 8. In addition, a reinforcing rib 9 is formed on the side of the plate body 6 facing the first side. The reinforcing rib 9 is annular and surrounds the end of the receiving groove 8 away from the mounting hole 5 in the axial direction of the rotating shaft 2 to strengthen the structural strength of the receiving groove 8.

[0071] According to some embodiments of the present invention, the mounting plate 20 constitutes an air guide plate. That is, the mounting hole 5 is formed on the air guide plate, and the air guide louver 10 is mounted on the air guide plate, so that the air guide assembly 100 can adjust the gas flow direction through the air guide plate and the air guide louver 10 arranged on the air guide plate, which can better improve the air guide flexibility of the air guide assembly 100.

[0072] According to some embodiments of the utility model, it is characterized in that the air guide plate includes an outer plate and an inner plate which are stacked, an insulation cavity is provided between the outer plate and the inner plate, a mounting hole 5 is formed on the inner plate, and the blade 1 is located on the side of the inner plate away from the outer plate. Therefore, during the use of the air guide plate, the heat transfer between the outer plate and the inner plate can be effectively reduced through the insulation cavity between the outer plate and the inner plate. For example, in the cooling mode, the heat transfer from the inner plate to the outer plate and the condensation caused by the temperature reduction of the outer plate can be effectively avoided through the insulation cavity, so that the condensation on the outer plate can be effectively avoided, which is conducive to improving the use experience of the air guide assembly 100.

[0074] The air conditioner according to the third aspect of the embodiment of the utility model includes: an air guide assembly 100.

[0075] According to the air conditioner of the third aspect of the utility model, the deformation resistance of the first shaft segment 21 can be improved to avoid deformation and fracture of the first shaft segment 21 when force is applied. At the same time, the connection between the rotating shaft 2 and the blade 1 through the first shaft segment 21 can improve the connection strength between the rotating shaft 2 and the blade 1, thereby avoiding fracture at the connection position between the rotating shaft 2 and the blade 1, which is beneficial to improving the overall structural stability of the air guide louver 10 to extend the service life of the air guide louver 10.
