[0043] In this application, "multiple" means two or more (including two).

[0044] The following is for reference. Figures 1-8 This invention describes an air guide assembly 100 and an air conditioner 1000 according to embodiments of the present invention.

[0045] like Figure 1 As shown, this application proposes an air guide assembly 100, including: a fixed base 10 and air guide blades 20. Multiple air guide blades 20 can be arranged on the fixed base 10. The multiple air guide blades 20 can be arranged in rows, columns or arrays on the fixed base 10, and the air guide blades 20 can rotate relative to the fixed base 10 to guide the airflow.

[0046] Among them, such as Figure 2 , Figure 4 as well as Figure 6 As shown, the fixed base 10 has a first mounting part 11, and the air guide vane 20 has a first rotating shaft 21 located on its rotation axis on the side facing the fixed base 10. The first rotating shaft 21 is rotatably disposed on the first mounting part 11 and is adapted to switch between the upper limit position a and the lower limit position b.

[0047] Specifically, such as Figure 3 and Figure 7 As shown, the guide vane 20 and the fixed base 10 are rotatably engaged via the first rotating shaft 21, so as to... Figure 3 The upper limit position a and shown Figure 7 It can switch between the lower limit position b shown, and can stay at any position including the upper limit position a and the lower limit position b (e.g., Figure 5 The guide vane 20 shown is in a horizontal position to achieve an appropriate air outlet angle.

[0048] It is understandable that during the swinging process between the upper limit position a and the lower limit position b, the air guide blade 20 may experience shaking, jamming, or other phenomena due to the influence of its own weight and the assembly gap between the first rotating shaft 21 and the first mounting part 11.

[0049] Based on this, the present application further forms a limiting part 30 on the first mounting part 11 and / or the first rotating shaft 21. The limiting part 30 protrudes along the axial direction of the guide vane 20 and extends circumferentially along the guide vane 20. The limiting part 30 has a first end 30a and a second end 30b in the extending direction. In the direction from the first end 30a to the second end 30b of the limiting part 30, the protrusion size of the limiting part 30a gradually increases. At the lower limit position a, the second end 30b of the limiting part 30 pushes against the first mounting part 11 or pushes against the guide vane 20.

[0050] In other words, the first end 30a of the limiting part 30 has the smallest axial protrusion, while the second end 30b has the largest axial protrusion. The limiting part 30 is arranged around the axis of the guide vane 20 so that during the process of the guide vane 20 switching from the upper limit position a to the lower limit position b, the second end 30b can gradually push against the first mounting part 11 (i.e., the limiting part 30 is formed on the guide vane 20), or the second end 30b can gradually push against the guide vane 20 (i.e., the limiting part 30 is formed on the fixing seat 10).

[0051] The limiting part 30, whose protrusion gradually increases in size, can push the limiting part 30 against the fixed seat 10 and / or the guide vane 20 when the guide vane 20 is at the lower limit position b.

[0052] Specifically, a limiting part 30 can be provided on the first mounting part 11, or on the first rotating shaft 21, or both the first mounting part 11 and the first rotating shaft 21 can be provided with limiting parts 30. Based on the fact that the air guide blade 20 is prone to shaking and jamming during its downward rotation from the upper limit position a to the lower limit position b, the limiting part 30 is configured to extend circumferentially to adapt to the movement trajectory of the air guide blade 20. The limiting part 30 is constructed to protrude axially relative to the air guide blade 20, and the protrusion size gradually increases. When the air guide blade 20 is at the lower limit position b, the limiting part 30 formed on the first rotating shaft 21 can push against the first mounting part 11, or the limiting part 30 formed on the first mounting part 11 can push against the first rotating shaft 21. Through the pushing and engaging, the fit gap between the first rotating shaft 21 and the first mounting part 11 is reduced, thereby reducing shaking. Furthermore, as the protrusion size gradually increases, the probability of jamming during the rotation of the air guide blade 20 can be reduced.

[0053] According to the embodiment of this application, the air guide assembly 100, by providing a limiting part 30 and making the limiting part 30 protrude axially and extend circumferentially, reduces the fitting clearance between the first rotating shaft 21 and the first mounting part 11 when the air guide blade 20 is at the lower limit position b. This can effectively improve the vibration of the air guide blade 20 during movement and reduce the probability of jamming or uneven rotation, thereby improving the air guiding effect, reducing abnormal noise, and improving the user experience.

[0054] According to some embodiments of this application, the limiting part 30 includes: a first limiting part 31 formed on the end face of the first mounting part 11 facing the guide vane 20 or away from the guide vane 20; and a second limiting part 32 formed on the guide vane 20, the second limiting part 32 being disposed opposite to the end face of the guide vane 20.

[0055] It is understood that the limiting part 30 may include a first limiting part 31 and a second limiting part 32. The first limiting part 31 and the second limiting part 32 may push against each other to achieve limiting cooperation. Alternatively, the first limiting part 31 may push against the first rotating shaft 21 and the second limiting part 32 may push against the first mounting part 11 to achieve consistent vibration of the guide vane 20. The first limiting part 31 and the second limiting part 32 may be provided in pairs, or only the first limiting part 31 or only the second limiting part 32 may be provided.

[0056] For example, the first limiting part 31 can be formed on one or both sides of the first mounting part 11. The first limiting part 31 can be formed on the side of the first mounting part 11 facing the guide vane 20 and the side of the first mounting part 11 away from the guide vane 20. The first rotating shaft 21 passes through the first mounting part 11. The corresponding second limiting part 32 can be formed on the part of the first rotating shaft 21 that passes through the first mounting part 11, or it can be formed on the part of the first rotating shaft 21 that does not pass through the first mounting part 11.

[0057] It is understandable that in embodiments where both the first limiting part 31 and the second limiting part 32 are provided, and the first limiting part 31 and the second limiting part 32 are opposite to each other, that is, both are located on the side of the fixed base 10 facing the guide vane 20, or both are located on the side of the fixed base 10 away from the guide vane 20, when the guide vane 20 is in the lower limit position b, the second end 30b of the first limiting part 31 is opposite to and in contact with the second end 30b of the second limiting part 32. When the guide vane 20 is in the upper limit position a, the first end 30a of the first limiting part 31 is opposite to and spaced apart from the second end 30b of the second limiting part 32, so as to reduce the matching gap between the first rotating shaft 21 and the first mounting part 11 through the cooperation of the first limiting part 31 and the second limiting part 32.

[0058] In other words, when the guide vane 20 is at the upper limit position a, the first end 30a of the first limiting part 31 and the second end 30b of the second limiting part 32 are opposite each other. At this time, the sum of their protruding dimensions is less than the fitting clearance. The sum of their protruding dimensions at this time is defined as the first dimension. When the guide vane is at the lower limit position b, the second end 30b of the first limiting part 31 and the second end 30b of the second limiting part 32 are opposite and in contact. At this time, the first limiting part 31 and the second limiting part 32 push against each other. The sum of their protruding dimensions should be less than or equal to the fitting clearance. The sum of their protruding dimensions at this time is defined as the second dimension. The second dimension is greater than the first dimension to suppress the vibration of the guide vane 20.

[0059] It is understandable that the first end 30a is the lowest point of the protrusion of the limiting part 30, while the second end 30b is the highest point of the protrusion of the limiting part 30.

[0060] It should be noted that the end face refers to the side surface of the first mounting part 11 facing the guide vane 20 or the side surface of the first mounting part 11 away from the guide vane 20. The surface of the guide vane 20 opposite to the end face can be the side surface of the guide vane 20 facing the fixed seat 10, or the surface of the guide vane 20 defined by the part of the first rotating shaft 21 passing through the first mounting part 11.

[0061] Combination Figures 2-7As shown, according to some embodiments of this application, the sum of the protrusion size of the second end 30b of the first limiting part 31 and the protrusion size of the second end 30b of the second limiting part 32 is less than or equal to the fitting clearance between the first rotating shaft 21 and the first mounting part 11.

[0062] It is understandable that the first limiting part 31 can push against the first rotating shaft 21 or the air guide blade 20, and the second limiting part 32 can push against the first fixed seat 10 to reduce the gap between the first rotating shaft 21 and the first mounting part 11 when the air guide blade 20 is in the lower limit position b. As the air guide blade 20 rotates, the protrusion size of the first limiting part 31 and the second limiting part 32 gradually increases, which can gradually achieve the pushing and matching to suppress vibration and achieve motion guidance, thereby reducing the probability of motion jamming.

[0063] Furthermore, limiting the sum of the protruding dimensions to be less than or equal to the fit clearance between the first rotating shaft 21 and the first mounting part 11 can further improve the fit and guiding effect between the first limiting part 31 and the second limiting part 32, and can avoid the phenomenon that the air guide blade 20 is stuck at the lower limit position b due to excessively large protruding dimensions of the first limiting part 31 or the second limiting part 32, thereby improving the working stability and reliability of the air guide assembly 100.

[0064] like Figure 3 , Figure 5 as well as Figure 7 As shown, according to some embodiments of this application, the first rotating shaft 21 includes: a first shaft segment 211, a first limiting flange 212 is provided at one end of the first shaft segment 211 adjacent to the air guide blade 20, a second limiting portion 32 is formed on the side surface of the first limiting flange 212 facing the fixed base 10, and a first limiting portion 31 is formed on the end surface of the first mounting portion 11 facing the air guide blade 20.

[0065] In other words, in the embodiment where both the first limiting part 31 and the second limiting part 32 are located on the side of the fixed base 10 facing the guide vane 20, the first limiting part 31 is formed on the end face of the first mounting part 11 facing the guide vane 20, while the second limiting part 32 is formed on the first limiting flange 212. This allows the relative position adjustment between the highest point of the second limiting part 32 and the first limiting part 31 during the synchronous rotation of the guide vane 20, achieving dynamic adjustment between the first limiting part 31 and the second limiting part 32. When the guide vane 20 is at the upper limit position a, the size of the fit between the first limiting part 31 and the second limiting part 32 is minimized, while when the guide vane 20 is at the lower limit position b, the size of the fit between the first limiting part 31 and the second limiting part 32 is maximized, thus achieving dynamic adjustment. This increases the fit size when the guide vane 20 swings downward to suppress shaking and reduce the probability of jamming.

[0066] Of course, the positions of the first limiting part 31 and the second limiting part 32 in the embodiments of this application are not limited to this. In some other embodiments, the first rotating shaft 21 further includes a second shaft segment 213. The first shaft segment 211 and the second shaft segment 213 are arranged in sequence in the direction away from the air guide blade 20. A second limiting flange 214 is provided at one end of the second shaft segment 213 adjacent to the air guide blade 20. A second limiting part 32 is formed on the side surface of the second limiting flange 214 facing the air guide blade 20. A first limiting part 31 is formed on the end surface of the first mounting part 11 away from the first rotating shaft 21.

[0067] In other words, in some other embodiments, the first limiting part 31 and the second limiting part 32 are both located on the side of the fixed base 10 away from the guide vane 20, but the technical effects that can be achieved are the same, and will not be described again here.

[0068] It should be noted that the first shaft segment 211 and the second shaft segment 213 are arranged sequentially in the direction away from the air guide blade 20. When the first rotating shaft 21 and the first mounting part 11 are in a mating state, the first limiting flange 212 and the second limiting flange 214 are located on both sides of the first mounting part 11 and limit the first rotating shaft 21. The limiting part 30 is provided between the first limiting flange 212 and the first mounting part 11, or between the second limiting flange 214 and the first mounting part 11. Both can adjust the mating gap to effectively reduce the vibration of the air guide blade 20 and improve the user experience.

[0069] According to some embodiments of this application, the first rotating shaft 21 includes: a plurality of split shaft portions 21a, the equivalent circles of the plurality of split shaft portions 21a defining the first rotating shaft 21, and the plurality of split shaft portions 21a being spaced apart along the axial direction of the first rotating shaft 21.

[0070] Thus, an elastic structure is formed between the multiple split shaft portions 21a. By overcoming the elastic force, at least a portion of the first rotating shaft 21 can pass through the first mounting portion 11, and the portion of the first rotating shaft 21 that passes through the first mounting portion 11 can also be radially elastically pushed against the mounting hole of the first mounting portion 11, thereby improving the stability and reliability of the fit between the first rotating shaft 21 and the first mounting portion 11. In the embodiment where both the first limiting portion 31 and the second limiting portion 32 are located on the side of the first mounting portion 11 away from the guide vane 20, constructing the first rotating shaft 21 as multiple split shaft portions 21a can also improve the fit and limiting effect of the first limiting portion 31 and the second limiting portion 32.

[0071] like Figure 1As shown, according to some embodiments of this application, the air conditioner 1000 further includes: a connecting rod 40 having a second mounting portion 41, and the air guide vane 20 further includes: a second rotating shaft 22 eccentrically disposed relative to the first rotating shaft 21, the second rotating shaft 22 being rotatably disposed on the second mounting portion 41, and the air guide vane 20 being adapted to switch between an upper limit position a and a lower limit position b under the drive of the connecting rod 40.

[0072] like Figure 1 , Figure 3 and Figure 7 As shown, according to some embodiments of this application, when the guide vane 20 is at the upper limit position a, the second rotating shaft 22 is located above the first rotating shaft 21, and when the guide vane 20 is at the lower limit position b, the second rotating shaft 22 is located below the first rotating shaft 21.

[0073] Therefore, based on the different positions of the second rotating shaft 22 relative to the first rotating shaft 21 at the upper limit position a and the lower limit position b, the extension direction of the first limiting part 31 and the second limiting part 32, the highest and lowest protruding points of the first limiting part 31, and the highest and lowest protruding points of the second limiting part 32, i.e. the positions of the first end 30a and the second end 30b, can be determined to reduce the processing difficulty of the limiting part 30.

[0074] It should be noted that the end near the upper limit position a refers to the end of the second limiting part 32 near the second rotating shaft 22, while the end towards the lower limit position b refers to the end of the second limiting part 32 away from the second rotating shaft 22.

[0075] Combination Figures 2-7 As shown, according to some embodiments of this application, the air guide blade 20 is provided with an avoidance recess 23, the second rotating shaft 22 is formed in the avoidance recess 23, and the second rotating shaft 22 is located on the side of the first limiting flange 212 of the first rotating shaft 21 away from the fixed seat 10.

[0076] Therefore, the probability of interference between the air guide blade 20 and the connecting rod 40 during the movement of the air guide blade 20 driven by the connecting rod 40 can be reduced, thereby improving the working stability and reliability of the air guide assembly 100.

[0077] like Figure 8 As shown, this application proposes an air conditioner 1000, including: the air guide assembly 100 in the above embodiment.

[0078] According to the embodiments of this application, the air conditioner 1000 adopts the above-mentioned air guide component 100, which can reduce the vibration and jamming of the air guide component 100 during operation, thereby reducing the air output effect of the air conditioner 1000 and reducing the abnormal noise of the air conditioner 1000, thereby improving the user experience of the air conditioner 1000.

[0079] The air guide assembly 100 and other components and operations of the air conditioner 1000 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
