Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air sweeping blade assembly component and an air conditioner. Background Art

[0002] Air conditioners typically have sweep blades installed at their air outlets to provide a left-hand swing function. The sweep blade's rotating shaft and stop protrusions pass through a special-shaped through-hole in the air conditioner's air outlet bracket, enabling a pivotable connection between the sweep blade and the bracket. However, in related art, the special-shaped through-holes in the brackets are relatively small. When installing the sweep blade, the special-shaped through-holes are easily completely blocked by the blade, making it more difficult to pass the rotating shaft and stop protrusion through the special-shaped through-holes, resulting in inefficient assembly of the sweep blade and bracket.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] The following combination Figures 1-6 A wind sweeping blade assembly according to an embodiment of the present invention is described.

[0030] The wind sweeping blade assembly of the embodiment of the present utility model includes a wind sweeping blade 1 and a bracket 2. The wind sweeping blade 1 includes a rotating shaft 11, a first limiting protrusion 12, and a second limiting protrusion 13. The first limiting protrusion 12 and the second limiting protrusion 13 are both arranged on the outer circumferential surface of the rotating shaft 11 and spaced apart along the axial direction of the rotating shaft 11. The bracket 2 includes a mounting plate 21. The outer surface of the mounting plate 21 is provided with a circular hole 211 and a first limiting hole 212 that are connected to each other. The rotating shaft 11 is pivotally engaged in the circular hole 211. The first limiting protrusion 12 is adapted to pass through the first limiting hole 212 to be located on the side of the mounting plate 21 facing away from the second limiting protrusion 13. The second limiting protrusion 13 partially blocks the first limiting hole 212.

[0031] According to the air-sweeping blade assembly component of the embodiment of the present utility model, the first limiting protrusion 12 and a part of the rotating shaft 11 in the air-sweeping blade 1 respectively pass through the first limiting hole 212 and the circular hole 211 to be located on the side of the mounting plate 21 away from the second limiting protrusion 13. Subsequently, rotate the air-sweeping blade 1 to stagger the first limiting hole 212 and the first limiting protrusion 12, and then the mounting plate 21 can be limited between the first limiting protrusion 12 and the second limiting protrusion 13, so as to realize the installation of the air-sweeping blade 1 on the bracket 2. Among them, by setting that the second limiting protrusion 13 only blocks a part of the first limiting hole 212, when installing the air-sweeping blade 1, the first limiting protrusion 12 can be aligned with the first limiting hole 212 more quickly, and then it is convenient for the first limiting protrusion 12 to quickly pass through the first limiting hole 212, effectively improving the assembly efficiency of the air-sweeping blade 1 and the bracket 2.

[0032] It should be noted that the air-sweeping blade 1 further includes an air-sweeping body for the air-sweeping function, and the air-sweeping body is connected to the end of the rotating shaft 11 away from the first limiting protrusion 12.

[0033] In some embodiments, as Figure 2 and Figure 3 shown, a part of the outer surface of the mounting plate 21 is recessed to form a groove 214, the circular hole 211 and at least a part of the first limiting holes 212 are arranged on the bottom surface of the groove 214, and the second limiting protrusion 13 is located in the groove 214.

[0034] That is, the second limiting protrusion 13 is hidden in the groove 214, thereby effectively preventing users from observing the second limiting protrusion 13 and the exposed part of the first limiting holes 212, and effectively improving the appearance beauty of the air conditioner at the air-sweeping blade 1.

[0035] Exemplarily, the depth of the groove 214 is greater than or equal to the dimension of the second limiting protrusion 13 in the axial direction of the rotating shaft 11.

[0036] In some embodiments, as Figure 2 and Figure 6 shown, the groove 214 is a circular groove, the radius of the outer contour of the cross-section of the groove 214 is L1, and the maximum distance between the inner wall surface of the first limiting hole 212 and the axis of the circular hole 211 is L2, wherein, L2 ≤ L1.

[0037] That is, all the first limiting holes 212 are arranged on the bottom surface of the groove 214, effectively preventing the first limiting holes 212 from affecting the appearance beauty of the air conditioner at this position due to partial exposure outside the groove 214.

[0038] Exemplarily, as Figure 6 shown, the maximum distance between the inner wall surface of the first limiting hole 212 and the axis of the circular hole 211 is equal to the radius of the outer contour of the cross-section of the groove 214, that is, the inner wall surface of the first limiting hole 212 is tangent to the inner wall surface of the groove 214.

[0039] In some embodiments, such as Figure 2 and Figure 3 shown, the second limiting protrusion 13 is an annular plate extending along the circumferential direction of the rotating shaft 11 and connected end to end, and the annular plate is in clearance fit in the groove 214.

[0040] Thus, during the pivoting process of the air-sweeping blade 1 relative to the bracket 2, the second limiting protrusion 13 will always block part of the first limiting hole 212, thereby preventing the second limiting protrusion 13 from passing through the first limiting hole 212 and affecting the limiting reliability of the air-sweeping blade 1 and the mounting plate 21 in the axial direction of the rotating shaft 11.

[0041] It should be noted that, as Figure 2 shown, there may be a relatively obvious gap between the outer peripheral surface of the annular plate and the inner wall surface of the groove 214 to expose more first limiting holes 212. Or, as Figure 3 shown, there may be a small gap between the outer peripheral surface of the annular plate and the inner wall surface of the groove 214, and only a little first limiting hole 212 needs to be exposed to facilitate the alignment of the first limiting protrusion 12 with the first limiting hole 212. At this time, the appearance beauty of the air conditioner at this place is further improved.

[0042] In some embodiments, such as Figures 4-6 shown, on the projection plane perpendicular to the axial direction of the rotating shaft 11, the projection outer contour of the first limiting protrusion 12 matches the projection outer contour of the first limiting hole 212.

[0043] At this time, the first limiting protrusion 12 can pass through the first limiting hole 212 along the axial direction of the rotating shaft 11 without needing to pass through the first limiting hole 212 obliquely. While further improving the assembly efficiency, it also avoids jitter and abnormal noise caused by scratching the rotating shaft 11 due to oblique installation.

[0044] Specifically, the projection of the first limiting protrusion 12 is a combination of a rectangle and a semicircle.

[0045] In some embodiments, such as Figure 5 and Figure 6 shown, the maximum dimension L3 of the first limiting hole 212 in the circumferential direction of the circular hole 211 is smaller than the diameter of the circular hole 211.

[0046] Correspondingly, the maximum dimension of the first limiting hole 212 in the circumferential direction of the rotating shaft 11 is smaller than the diameter of the circular hole 211. Thus, after the first limiting protrusion 12 passes through the first limiting hole 212, based on the dislocation of the first limiting protrusion 12 and the first limiting hole 212, the air-sweeping blade 1 can pivot at a larger angle relative to the bracket 2, and the pivoting installation reliability of the air-sweeping blade 1 on the bracket 2 is higher.

[0047] Specifically, as Figure 6As shown, the second limiting hole 212 is composed of a rectangular hole and a semicircular hole, and the maximum dimension L3 of the first limiting hole 212 in the circumferential direction of the rotating shaft 11 is the diameter of the semicircular hole and the width of the rectangular hole.

[0048] In some embodiments, as Figures 4-6 As shown, the wind-sweeping blade 1 further includes a third limiting protrusion 14, which is disposed on the outer circumferential surface of the rotating shaft 11. The third limiting protrusion 14 and the first limiting protrusion 12 are spaced apart along the circumference of the rotating shaft 11. The outer surface of the mounting plate 21 further includes a second limiting hole 213 that communicates with the circular hole 211. The third limiting protrusion 14 is adapted to pass through the second limiting hole 213 to be located on the side of the mounting plate 21 facing away from the second limiting protrusion 13.

[0049] At this time, after the wind sweeping blade 1 is installed on the bracket 2, the first limiting protrusion 12 and the third limiting protrusion 14 jointly prevent the wind sweeping blade 1 from separating from the bracket 2, effectively preventing the wind sweeping blade 1 from deflecting when rotating relative to the bracket 2 and increasing the rotational friction, thereby causing the wind sweeping blade 1 to shake and make abnormal noises.

[0050] Specifically, the first limiting protrusion 12 and the third limiting protrusion 14 are located at the same position of the rotating shaft 11 along the axial direction of the rotating shaft 11, and the surface of the first limiting protrusion 12 facing the second limiting protrusion 13 and the surface of the third limiting protrusion 14 facing the second limiting protrusion 13 are coplanar.

[0051] In some embodiments, as Figures 4-6 As shown, on a projection surface perpendicular to the axial direction of the rotating shaft 11 , the projected outer contour of the third limiting protrusion 14 matches the projected outer contour of the second limiting hole 213 .

[0052] At this time, the third limiting protrusion 14 can pass through the second limiting hole 213 along the axial direction of the rotating shaft 11 without being tilted to pass through the second limiting hole 213, which further improves the assembly efficiency and avoids shaking and abnormal noise caused by scratching the rotating shaft 11 due to tilted installation.

[0053] Specifically, the projection of the second limiting protrusion 13 is a rectangle.

[0054] In some embodiments, the first limiting protrusion 12 and the third limiting protrusion 14 are respectively disposed on two opposite sides of the rotating shaft 11 along the radial direction of the rotating shaft 11 .

[0055] In this way, the coaxiality of the rotating shaft 11 and the circular hole 211 is further maintained, and the rotating shaft 11 is less likely to deviate relative to the circular hole 211 and wear, further preventing vibration and abnormal noise from occurring when the wind sweeping blade 1 rotates.

[0056] like Figure 2 and Figure 3As shown, the second limiting protrusion 13 blocks the second limiting hole 213, that is, the size of the second limiting hole 213 is smaller than that of the first limiting hole 212, thereby effectively improving the structural strength of the mounting plate 21 here and further enhancing the aesthetic appearance of the air conditioner here.
