[0030] In order to solve the problem in the prior art that the overall space occupied by the air guide plate ejection mechanism is large and thus the processing cost of the air conditioner is increased, the present application provides an air guide mechanism and an air conditioner having the same.

[0031] like Figures 1 to 7 As shown, the air guide mechanism is used to close or avoid the air outlet 10 of the air conditioner. The air guide mechanism includes a housing 20, a driving device 30, a transmission assembly 40 and an air guide plate 50. The housing 20 has an installation cavity 21, an opening 22 and a through hole, and the opening 22 and the through hole are both connected to the installation cavity 21. The driving device 30 is arranged on the housing 20, and the driving shaft 31 of the driving device 30 extends into the installation cavity 21 after passing through the through hole. The transmission assembly 40 includes a gear 41 and a rack 42 meshed with the gear 41. The gear 41 is located in the installation cavity 21, and at least part of the rack 42 can extend out of the installation cavity 21 through the opening 22 or retract into the installation cavity 21 through the opening 22. The driving shaft 31 is drivingly connected to the gear 41. The air guide plate 50 is connected to the rack 42. Among them, the driving device 30 drives the gear 41 to rotate, so as to drive the rack 42 to move along its extension direction through the gear 41, so that the air guide plate 50 closes or avoids the air outlet 10.

[0032] Applying the technical solution of this embodiment, the air guide mechanism includes a driving device 30 and a transmission assembly 40, the transmission assembly 40 includes a gear 41 and a rack 42 meshing with the gear 41, the driving shaft 31 of the driving device 30 is drivingly connected to the gear 41, and the air guide plate 50 is connected to the rack 42, the driving device 30 drives the gear 41 to rotate, so as to drive the rack 42 to move along its extension direction through the gear 41, so that the air guide plate 50 closes or avoids the air outlet 10. In this way, the air guide mechanism in this embodiment adopts the driving device 30 to drive the gear 41 to rotate, and then the gear 41 drives the rack 42 and the air guide plate 50 to move to realize the movement of the air guide plate 50. That is, the driving device 30, the gear 41 and the rack 42 are small driving components, which can not only meet the functional requirements, but also reduce the overall occupied space of the power part of the air guide mechanism, make full use of the internal space of the air conditioner, and realize the miniaturization design of the air conditioner, thereby solving the problem of the large overall occupied space of the air guide plate ejection mechanism in the prior art and increasing the processing cost of the air conditioner, reducing the labor intensity of the staff, reducing the processing cost of the air conditioner, and improving the production efficiency of the air conditioner.

[0033] In this embodiment, a small drive assembly is formed by the drive device 30, the gear 41 and the rack 42, thereby reducing the overall space occupied by the air guide mechanism, reducing the length or width of the air conditioner, reducing the processing cost of the air conditioner, and shortening the production cycle.

[0034] like Figures 3 to 7 As shown, the installation cavity 21 is an arc-shaped cavity, and the rack 42 is arc-shaped, so that the gear 41 drives the rack 42 to move in the arc-shaped cavity. Among them, the center of the driving device 30 and the rack 42 are located on the same side. In this way, the above-mentioned setting realizes the rotation of the air guide plate 50 around the preset axis, thereby closing or opening the air outlet 10, and improving the operating reliability of the air guide plate 50. At the same time, since the installation cavity 21 and the rack 42 are both arc-shaped, the length or width of the housing 20 and the transmission assembly 40 is further reduced, thereby reducing the overall occupied space of the air guide mechanism, and realizing the miniaturized design of the air conditioner.

[0035] Specifically, the preset axis and the center of the rack 42 are located on the same side, and the drive device 30 is located in the area surrounded by the rack 42 to fully utilize the internal space of the air conditioner and reduce the overall occupied space of the small drive assembly.

[0036] In this embodiment, the gear 41 is a bevel gear, and the small end of the bevel gear is arranged relative to the large end near the center of the rack 42. In this way, the above arrangement ensures that the gear 41 can drive the rack 42 to move along its extension direction, so as to realize the opening or closing of the air outlet 10 by the air guide plate 50, thereby improving the transmission reliability of the transmission assembly 40.

[0037] like Figure 3 and Figure 4 As shown, the air guide plate 50 is connected to the first end of the rack 42, the housing 20 has a first guide portion 23, and the second end of the rack 42 is provided with a second guide portion 43, one of the first guide portion 23 and the second guide portion 43 is a first protrusion, and the other of the first guide portion 23 and the second guide portion 43 is a first recess, and the first protrusion extends into the first recess and can slide along the first recess. In this way, the first guide portion 23 and the second guide portion 43 cooperate with each other to limit the movement of the rack 42 relative to the housing 20, and further ensure that the rack 42 moves along its extension direction, so that the air guide plate 50 moves on a preset track. At the same time, the above-mentioned arrangement makes the structure of the first guide portion 23 and the second guide portion 43 simpler, easier to process and realize, and reduces the processing cost and difficulty of the two.

[0038] In this embodiment, the first guide portion 23 is a first recessed portion, and the second guide portion 43 is a first protrusion, so that the processing of the first guide portion 23 and the second guide portion 43 is easier and simpler, thereby reducing the processing cost and difficulty of the two.

[0039] It should be noted that the structures of the first guide portion 23 and the second guide portion 43 are not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the first guide portion 23 is a first protrusion and the second guide portion 43 is a first recess, so that the structures of the first guide portion 23 and the second guide portion 43 are more diverse to meet different usage requirements and working conditions, and also improve the processing flexibility of the staff.

[0040] like Figure 3 , Figure 4 and Figure 7 As shown, there are two first guide portions 23, and the housing 20 includes a first housing 26 and a second housing 24. One first guide portion 23 is arranged on the first housing 26. The second housing 24 is arranged opposite to the first housing 26 and forms a mounting cavity 21 and an opening 22 with the first housing 26, and another first guide portion 23 is arranged on the second housing 24. Among them, there are two second guide portions 43, and the two second guide portions 43 are respectively arranged on both sides of the rack 42. In this way, the first housing 26 and the second housing 24 are docked and form a mounting cavity 21, and the rack 42 is located between the two housings, and the two housings can protect the rack 42. At the same time, the above arrangement increases the contact area between the first guide portion 23 and the second guide portion 43, thereby improving the guiding reliability of the two, and ensuring that the rack 42 moves along its extension direction.

[0041] Specifically, the two first guide portions 23 and the two second guide portions 43 are arranged in one-to-one correspondence, and each second guide portion 43 extends into the first guide portion 23 corresponding thereto and can slide along the first guide portion 23 .

[0042] It should be noted that the number of the first guide portions 23 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the first guide portions 23 is one, three, four, or more.

[0043] It should be noted that the number of the second guide portions 43 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the second guide portions 43 is one, three, four, or more.

[0044] In this embodiment, the first recess is arc-shaped, and the central axis of the first recess is coaxially arranged with the central axis of the rack 42. Thus, the above arrangement ensures that the rack 42 can move along the first recess, and improves the guiding reliability of the first guide part 23 to the rack 42.

[0045] Specifically, the first recess is an arc-shaped through hole, so that the structure of the first recess is simpler, easier to process and realize, and the processing cost of the first recess is reduced.

[0046] It should be noted that the structure of the first recess is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the first recess is an arc-shaped groove.

[0047] like Figure 5 and Figure 6 As shown, the first protrusion includes a first rotating shaft 431 and a first sleeve 432. The first sleeve 432 is sleeved outside the first rotating shaft 431 and can rotate relative to the first rotating shaft 431. In this way, the first sleeve 432 contacts the inner surface of the first recess so that there is rolling friction between the two, thereby reducing the friction between the first guide portion 23 and the second guide portion 43, reducing the structural wear of the air guide mechanism, and extending the service life of the air guide mechanism.

[0048] like Figure 4 and Figure 6 As shown, the rack 42 has a third guide portion 421 arranged opposite to the second housing 24, and the second housing 24 is provided with a fourth guide portion 25, one of the third guide portion 421 and the fourth guide portion 25 is a second protrusion, and the other of the third guide portion 421 and the fourth guide portion 25 is a second recess, and the second protrusion extends into the second recess and can slide along the second recess; wherein the third guide portion 421 is located between the first end and the second end of the rack 42. In this way, the third guide portion 421 and the fourth guide portion 25 cooperate with each other to limit the movement of the rack 42 relative to the housing 20, and further ensure that the rack 42 moves along its extension direction, so that the air guide plate 50 moves on a preset track. At the same time, the above arrangement makes the structure of the third guide portion 421 and the fourth guide portion 25 simpler, easier to process and realize, and reduces the processing cost and difficulty of the two.

[0049] Specifically, the second guide portion 43 is disposed at the second end of the rack 42, and the third guide portion 421 is located between the first end of the rack 42 and the second guide portion 43 to guide the middle portion of the rack 42, thereby ensuring that the rack 42 moves along its extension direction.

[0050] In this embodiment, the third guide portion 421 is a second recessed portion, and the fourth guide portion 25 is a second protrusion, so that the processing of the third guide portion 421 and the fourth guide portion 25 is easier and simpler, thereby reducing the processing cost and difficulty of the two.

[0051] Optionally, the second recess is an arc-shaped groove, and the second protrusion is multiple, and the multiple second protrusions are arranged at intervals along the extension direction of the arc-shaped groove. In this way, the above arrangement increases the contact area between the third guide portion 421 and the fourth guide portion 25, thereby improving the guiding reliability of the two, and ensuring that the rack 42 moves along its extension direction.

[0052] In this embodiment, there are four second protrusions, and the four second protrusions are arranged at intervals along the extension direction of the arc-shaped groove. It should be noted that the number of the second protrusions is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the second protrusion is one, two, three, five, or more.

[0053] like Figure 4 and Figure 7 As shown, the second protrusion includes a second rotating shaft 251 and a second sleeve 252. The second sleeve 252 is sleeved outside the second rotating shaft 251 and can rotate relative to the second rotating shaft 251. In this way, the second sleeve 252 contacts the inner surface of the second recess so that there is rolling friction between the two, thereby reducing the friction between the third guide portion 421 and the fourth guide portion 25, reducing the structural wear of the air guide mechanism, and extending the service life of the air guide mechanism.

[0054] Optionally, the central axis of the arc groove is coaxially arranged with the central axis of the rack 42, and the central angle corresponding to the arc groove is greater than or equal to 95° and less than or equal to 175°. In this embodiment, the central angle corresponding to the arc groove is 130°, so that the structure of the arc groove is simpler, easy to process and realize, and the processing cost of the arc groove is reduced.

[0055] It should be noted that the size of the central angle of the arc groove is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the central angle of the arc groove is 95°, or 100°, or 105°, or 110°, or 115°, or 120°, or 125°, or 135°, or 140°, or 145°, or 150°, or 155°, or 160°, or 165°, or 170°, or 175°.
