It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] like Figures 1 to 4 As shown, in one aspect, this application provides an air guiding device 1, which is applicable to an air conditioner 100. The air guiding device 1 includes an air guide plate 10, an adapter shaft 20, and a drive source 30, which can accurately align the air guide plate 10 and the adapter shaft 20, reducing assembly difficulty and improving assembly efficiency.

[0024] The air guide plate 10 is provided with a first shaft hole 12 and a guide structure 13, with the guide structure 13 arranged around the open end of the first shaft hole 12. In other words, the guide structure 13 can be formed on one side surface of the air guide plate 10 where the first shaft hole 12 is provided, and is arranged around the periphery of the open end of the first shaft hole 12.

[0025] The adapter shaft 20 has a connecting shaft end 21 and a second shaft hole 22 arranged opposite to each other, and the connecting shaft end 21 and the first shaft hole 12 are inserted and fixed. The drive source 30 is provided with an output shaft end 31, and the output shaft end 31 and the second shaft hole 22 are inserted and fixed. The type of drive source 30 can be determined according to actual needs, and can be different types such as drive motors, hydraulic motors, etc., which are not limited in this embodiment. After the adapter shaft 20 is connected to the air guide plate 10 and the drive source 30, the drive source 30 can drive the air guide plate 10 to swing and guide the air through the adapter shaft 20.

[0026] like Figure 3As shown, when the air guide plate 10 and the adapter shaft 20 need to be assembled, the guide structure 13 is used to align with the connecting shaft end 21 so that the central axis of the connecting shaft end 21 coincides with the central axis of the first shaft hole 12. In other words, the guide structure 13 is adapted to guide the connecting shaft end 21 of the adapter shaft 20 to be positioned at the guide structure 13. When the connecting shaft end 21 is positioned at the guide structure 13, the central axis of the connecting shaft end 21 coincides with the central axis of the first shaft hole 12, but the connecting shaft end 21 is still located outside the first shaft hole 12, so that the connecting shaft end 21 and the first shaft hole 12 complete the central axis alignment, achieving the purpose of centering and alignment.

[0027] After the connecting shaft end 21 of the adapter shaft 20 and the guide structure 13 are aligned, the connecting shaft end 21 can rotate around the central axis of the connecting shaft end 21 to align and insert with the first shaft hole 12. Figure 4 As shown, as the connecting shaft end 21 gradually rotates around its central axis, each side wall of the connecting shaft end 21 gradually aligns with each side wall of the first shaft hole 12, thereby completing the alignment of each side wall of the connecting shaft end 21 and the first shaft hole 12, so that the connecting shaft end 21 can be aligned and inserted into the first shaft hole 12.

[0028] Compared with related technologies, the air guide device 1 provided in this application embodiment has a guide structure 13 surrounding the first shaft hole 12 on the air guide plate 10. First, the guide structure 13 and the connecting shaft end 21 are aligned so that the central axis of the connecting shaft end 21 coincides with the central axis of the first shaft hole 12 to complete the central axis alignment. Then, the connecting shaft end 21 is controlled to rotate around the central axis of the connecting shaft end 21 so that each side wall of the connecting shaft end 21 gradually aligns with each side wall of the first shaft hole 12 one by one. This allows the connecting shaft end 21 to be quickly aligned with the first shaft hole 12 and inserted into the first shaft hole 12, thereby accurately and quickly realizing the shaft hole alignment between the air guide plate 10 and the adapter shaft 20, effectively reducing the assembly difficulty and improving the assembly efficiency.

[0029] The shapes of the first shaft hole 12 and the connecting shaft end 21 correspond to each other, and their combination type can be determined according to actual needs. It can be different types, such as polygonal hole-shaft combination, elliptical hole-shaft combination, square hole-shaft combination, etc., and this application embodiment does not limit this. In some embodiments, the first shaft hole 12 can be a square hole, and the connecting shaft end 21 can be a square shaft end. A square hole is a square hole, and a square shaft end is a square shaft end. When the first shaft hole 12 is a square hole, the opening end of the first shaft hole 12 has a square profile. When this square hole-shaft combination type is used, the side length of the cross-section of the first shaft hole 12 and the side length of the cross-section of the connecting shaft end 21 are relatively large, which can increase the transmittable torque between the first shaft hole 12 and the connecting shaft end 21, avoid misalignment and slippage between the air guide plate 10 and the adapter shaft 20, and improve the reliability of the transmission connection between the air guide plate 10 and the adapter shaft 20.

[0030] The specific construction of the guide structure 13 can be determined according to actual needs, and this application embodiment does not limit it in this regard. Figures 1 to 4 As shown, in some examples, the guide structure 13 may include at least one guide rib group 130. The guide rib group 130 may include two guide ribs 131 that are vertically connected or inclined, with the guide ribs 131 and the side of the opening end of the first shaft hole 12 inclined. The two guide ribs 131 of the guide rib group 130 are used to align and abut against two adjacent sidewalls of the connecting shaft end 21, so that the central axis of the connecting shaft end 21 coincides with the central axis of the first shaft hole 12. A corner portion is formed between the two adjacent sidewalls of the connecting shaft end 21, and the two guide ribs 131 of the guide rib group 130 can clamp and position this corner portion to achieve the purpose of centering and aligning the connecting shaft end 21 and the first shaft hole 12.

[0031] In some examples, the guide structure 13 may include multiple guide rib groups 130, each guide rib group 130 corresponding to one side of the opening end of the first shaft hole 12. Furthermore, the multiple guide rib groups 130 may correspond to multiple corner portions of the connecting shaft end 21, with each guide rib group 130 used to clamp and position one corner portion of the connecting shaft end 21. By using multiple guide rib groups 130 to clamp and position multiple corner portions respectively, it is further ensured that the central axis of the connecting shaft end 21 coincides with the central axis of the first shaft hole 12, thereby ensuring the centering and alignment accuracy of the connecting shaft end 21 and the first shaft hole 12.

[0032] For example, one end of the two guide edges 131 of the guide edge group 130 can intersect on the circumcircle of the opening end of the first shaft hole 12, and the other end can be connected to the side of the opening end of the first shaft hole 12 respectively. Here, the circumcircle of the opening end of the first shaft hole 12 is a circle that intersects with each vertex of the opening end. When the first shaft hole 12 is a square hole, the opening end of the first shaft hole 12 has a square profile. By setting the two guide edges 131 of the guide edge group 130 as described above, the relationship between the guide edge group 130 and the first shaft hole 12 can be defined more accurately, so that after the guide edge group 130 and a corner of the connecting shaft end 21 are clamped and positioned, the central axis of the connecting shaft end 21 and the central axis of the first shaft hole 12 are coincident, thereby ensuring the centering and alignment accuracy of the connecting shaft end 21 and the first shaft hole 12.

[0033] For example, a first included angle can be formed between the two guide edges 131 of the guide edge group 130, and a second included angle can be formed between the two adjacent sidewalls of the connecting shaft end 21, that is, the angle of the corner portion of the connecting shaft end 21 is the second included angle. The first included angle can be greater than the second included angle, and the angle difference between the first included angle and the second included angle is not greater than the angle deviation threshold. The specific value of the angle deviation threshold can be determined according to actual needs, and this application embodiment does not limit it; for example, the angle deviation threshold can be taken in the range of 5-20°, such as 5°, 8°, 10°, 12°, 15°, 18° or 20°. By setting the first included angle to be slightly greater than the second included angle, on the one hand, it is easier for the corner portion of the connecting shaft end 21 to be clamped and positioned between the two guide edges 131, improving the alignment convenience; on the other hand, it is possible to control the angle deviation when the corner portion of the connecting shaft end 21 is clamped and positioned between the two guide edges 131, ensuring alignment accuracy.

[0034] In some examples, the guide structure 13 may include a plurality of first guide ramps 132 and a plurality of second guide ramps 133. The first guide ramps 132 and second guide ramps 133 are respectively inclined to the central axis of the first shaft hole 12. The second guide ramps 133 and the first guide ramps 132 are formed on opposite sides of the guide ridge 131. Each first guide ramp 132 is correspondingly disposed on one side of the opening end of the first shaft hole 12. For example, each first guide ramp 132 may be disposed at the middle of one side of the opening end of the first shaft hole 12. Each second guide ramp 133 is disposed around a corner 121 of the opening end of the first shaft hole 12. For example, each second guide ramp 133 may include two second guide sub-ramps, which are disposed on both sides of a corner 121 of the opening end of the first shaft hole 12. The corner 121 is the connecting portion between adjacent side edges of the opening end of the first shaft hole 12. The first guide slope 132 and the second guide slope 133 can guide the connecting shaft end 21, making it easier for the connecting shaft end 21 to be aligned and rotated.

[0035] For example, the bottom of the first guide slope 132 can be connected to the side of the opening end of the first shaft hole 12, and the bottom of the second guide slope 133 can also be connected to the side of the opening end of the first shaft hole 12. In this way, the first guide slope 132 can extend obliquely inward from the outer circle of the first shaft hole 12 to the opening end of the first shaft hole 12, which facilitates the inward sliding alignment of the connecting shaft end 21 with the guide structure 13 and the rotational alignment of each side with the first shaft hole 12.

[0036] In some embodiments, a connecting arm 11 may be provided on the surface of the air guide plate 10, and a first shaft hole 12 and a guide structure 13 are respectively formed on the connecting arm 11. By providing a protruding connecting arm 11, the air guide plate 10 and the adapter shaft 20 can be easily connected, avoiding spatial interference.

[0037] like Figures 1 to 5 As shown, on the other hand, this application embodiment provides an air conditioner 100, which includes a housing 2 and an air guide device 1 as described in any of the above embodiments. The housing 2 is provided with an air outlet 201, and the air guide device 1 is disposed at the air outlet 201. The type of air conditioner 100 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, a ceiling-mounted air conditioner, etc., and this application embodiment does not limit this. The air conditioner 100 provided in this application embodiment has the aforementioned air guide device 1, which allows the air guide plate 10 and the adapter shaft 20 to be accurately aligned, reducing assembly difficulty and improving assembly efficiency.

[0038] The air guiding device and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.

Therefore, the content of this specification should not be construed as a limitation of this application.
