The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In order to solve the problem in the prior art that when the air guide plate is closed, there is a gap between the air guide plate and the panel, which affects the appearance of the air conditioner, the present application provides a drive assembly, an air guide assembly and an air conditioner.

[0034] like Figures 1 to 9As shown, the driving assembly is used to drive the air guide plate 10 of the air conditioner to move, and the driving assembly includes a first driving box 20 and a second driving box 30. The first driving box 20 includes a first driving device 21 and a first transmission mechanism, and the first transmission mechanism includes a first gear 22, a second gear 23, a first rack 24 and a second rack 25. The first end of the first rack 24 is used to connect with the first end of the air guide plate 10, and the second rack 25 is arranged on the second end of the first rack 24. The second driving box 30 includes a second driving device 31 and a second transmission mechanism drivingly connected to the second driving device 31, and the second transmission mechanism is connected to the second end of the air guide plate 10. Among them, the first driving box 20 has a first state and a second state. When the first driving box 20 is in the first state, the first gear 22 is meshed with the first rack 24, and the first driving device 21 is drivingly connected to the first gear 22; when the first driving box 20 is in the second state, the second gear 23 is meshed with the second rack 25, and the first driving device 21 is drivingly connected to the second gear 23. The module m2 of the second gear 23 is the same as the module m1 of the first gear 22 , and the number of teeth z2 of the second gear 23 is smaller than the number of teeth z1 of the first gear 22 .

[0035] By applying the technical solution of this embodiment, the first end of the air deflector 10 is a non-driven side, and the second gear 23 is a pinion compared to the first gear 22, so that a difference in the number of teeth is formed between the first drive box 20 and the second drive box 30 arranged at both ends of the air deflector 10, and when the operating parameters (such as the rotation speed) of the first drive device 21 and the second drive device 31 are consistent, the rotation angle of the second gear 23 in the first drive box 20 is greater than the rotation angle of the second transmission mechanism in the second drive box 30. In this way, when the air deflector 10 moves to the closed state, the first drive box 20 switches from the first state to the second state, so that the first drive device 21 is drivingly connected to the second gear 23, and the second gear 23 is meshed with the second rack 25, so as to drive the air deflector 10 to deflect through the second rack 25 and the first rack 24. In the above process, since the deflection angle of the air guide plate 10 driven by the first driving box 20 is greater than the deflection angle of the air guide plate 10 driven by the second driving box 30, the second end of the air guide plate 10 is subjected to a tensioning force, and the air guide plate 10 is fully closed on the panel, thereby solving the problem in the prior art that when the air guide plate is closed, there is a gap between the air guide plate and the panel, which affects the appearance of the air conditioner, improves the sealing and reliability of the closing of the air guide plate 10, and improves the appearance of the air conditioner.

[0036] In this embodiment, the driving parameters of the first driving device 21 and the second driving device 31 are consistent. Optionally, the first driving device 21 and the second driving device 31 are both motors, and the rotation speeds of the motors are consistent.

[0037] In this embodiment, the number of teeth z1 of the first gear 22 is 21, and the number of teeth z2 of the second gear 23 is 15. Thus, the above arrangement makes the structure of the first gear 22 and the second gear 23 simpler, easier to process and realize, and reduces the processing cost of the drive assembly.

[0038] It should be noted that the number of teeth of the first gear 22 and the second gear 23 is not limited thereto, as long as the number of teeth z2 of the second gear 23 is smaller than the number of teeth z1 of the first gear 22. Optionally, the number of teeth z1 of the first gear 22 is 20, or 22, or 25, or 28, or 30. Optionally, the number of teeth z2 of the second gear 23 is 16, or 18, or 20, or 22, or 25.

[0039] In this embodiment, the second gear 23 is arranged on the first gear 22 and is located inside the first gear 22, and the second gear 23 is arranged coaxially with the first gear 22. In this way, the second gear 23 is fixedly connected to the first gear 22 and is located inside the first gear 22, so that the first driving device 21 can drive the second gear 23 to rotate by driving the first gear 22 by the first driving device 21, thereby making it easier and simpler for the first driving device 21 to drive the second gear 23, and reducing the driving difficulty. At the same time, the above arrangement makes it easier and simpler to disassemble and assemble the first gear 22 and the second gear 23, and reduces the disassembly and assembly difficulty.

[0040] Specifically, along the direction from the first driving box 20 to the second driving box 30, the second rack 25 is located on the inner side of the first rack 24, so that the disassembly and assembly of the first driving box 20 is easier and simpler, and the difficulty of disassembly and assembly is reduced. At the same time, when the air guide plate 10 is switched from the first state to the second state, the second gear 23 is meshed with the second rack 25, and the first driving device 21 drives the second gear 23 to rotate, so as to drive the second rack 25 to move through the second gear 23. Since the second rack 25 is arranged on the first rack 24, the first rack 24 can be driven to move through the second rack 25, so as to realize the deflection of the air guide plate 10.

[0041] It should be noted that the positional relationship between the second gear 23 and the first gear 22 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the second gear 23 is located outside the first gear 22 and the second rack 25 is located outside the first rack 24 .

[0042] like Figure 2As shown, when the first driving box 20 is in the first state, the second gear 23 is located between the air guide plate 10 and the second rack 25, and the end of the second rack 25 facing the second gear 23 is arranged opposite to at least a portion of the first rack 24. In this way, the above arrangement ensures that there is an overlapping portion between the first rack 24 and the second rack 25, so as to ensure that the first rack 24 can drive the air guide plate 10 to deflect, thereby improving the driving reliability of the driving assembly on the air guide plate 10.

[0043] Specifically, the overlapped portion of the second rack 25 and the first rack 24 is 0.5d, where d is the tooth root width of the second rack 25 .

[0044] In this embodiment, the parameters of the first rack 24 and the second rack 25 are the same, including the pitch, the height of the tooth top, the height of the tooth root, the module and the tooth shape. Thus, the above arrangement makes the processing of the first rack 24 and the second rack 25 easier and simpler, and reduces the processing cost and difficulty of the drive assembly.

[0045] In this embodiment, the first rack 24 and the second rack 25 are both arc-shaped, and the first rack 24 and the second rack 25 are coaxially arranged. In this way, the above arrangement makes the processing of the first rack 24 and the second rack 25 easier and simpler, and reduces the processing cost and difficulty of the drive assembly.

[0046] Optionally, the difference between the root diameter of the first rack 24 and the root diameter of the second rack 25 is greater than or equal to 4 mm and less than or equal to 6 mm. In this way, when the first drive box 20 switches from the first state to the second state, the above setting ensures that the second gear 23 can mesh with the second rack 25, so that the offset angle of the first end of the air guide plate 10 driven by the first drive box 20 is greater than the offset angle of the second end of the air guide plate 10 driven by the first drive box 20, ensuring that the first drive box 20 can apply a tensioning force to the first end of the air guide plate 10, thereby effectively solving the problem of uneven closing gaps on both sides and the problem of the air guide plate closing due to insufficient tensioning force when the air supply angle mode of the single motor drives the air guide plate to be closed. At the same time, the above setting makes the selection of the difference between the root diameter of the first rack 24 and the root diameter of the second rack 25 more flexible to meet different usage requirements and working conditions.

[0047] In this embodiment, the difference between the root diameter of the first rack 24 and the root diameter of the second rack 25 is 4.6 mm. It should be noted that the selection of the difference between the root diameter of the first rack 24 and the root diameter of the second rack 25 is not limited to this, and can be adjusted according to working conditions and usage requirements. Optionally, the difference between the root diameter of the first rack 24 and the root diameter of the second rack 25 is 4.2 mm, or 4.5 mm, or 4.8 mm, or 5.0 mm, or 5.2 mm, or 5.5 mm, or 5.8 mm.

[0048] like Figures 6 to 8 As shown, the second transmission mechanism includes a third gear 32 and a third rack 33, the third rack 33 is meshed with the third gear 32, and the second drive device 31 is drivingly connected to the third gear 32. The second drive box also includes a third drive device 34. Among them, the third drive device 34 is arranged on the third rack 33, and the third drive device 34 is drivingly connected to the second end of the air guide plate 10 to drive the air guide plate 10 to rotate relative to the third rack 33. In this way, the above arrangement makes the structure of the second transmission mechanism simpler, easy to process and realize, and also improves the transmission stability of the second transmission mechanism. At the same time, the air guide plate 10 is driven to rotate relative to the third rack 33 by the third drive device 34 to achieve precise adjustment of the air outlet direction of the air guide plate 10.

[0049] Specifically, the parameters of the third gear 32 and the first gear 22 are consistent, and the parameters of the third rack 33 and the first rack 24 are consistent, so that the structure of the drive assembly is easier and simpler, and the processing cost and difficulty of the drive assembly are reduced.

[0050] Optionally, the third driving device 34 is a motor.

[0051] like Figure 6 and Figure 7 As shown, a clamping protrusion 341 is provided on the outer surface of the driving end of the third driving device 34, and the air deflector 10 includes an air deflector body 11 and a first connecting lug 12. The first connecting lug 12 is provided on the air deflector body 11, and the first connecting lug 12 has a first mounting recess, and the driving end extends into the first mounting recess so that the clamping protrusion 341 and the first mounting recess are limitedly matched. In this way, the clamping protrusion 341 and the first mounting recess are limitedly matched to ensure that the driving end and the air deflector 10 rotate synchronously in the circumferential direction. The above arrangement realizes the anti-rotation cooperation between the driving end and the air deflector 10, so as to ensure that the driving end can drive the air deflector 10 to rotate.

[0052] Optionally, the first mounting recess is a through hole, and the driving end is a motor shaft.

[0053] like Figures 2 to 5As shown, the first drive box 20 also includes a connecting column 26 and a fastener, and the connecting column 26 is arranged on the first rack 24. The air deflector 10 also includes a second connecting lug 13. Among them, the second connecting lug 13 is arranged on the air deflector body 11, and the second connecting lug 13 has a second mounting recess. The connecting column 26 extends into the second mounting recess, and the fastener is passed through the connecting column 26 and the second connecting lug 13 to connect the connecting column 26 and the second connecting lug 13. In this way, the above-mentioned arrangement makes the disassembly and assembly of the first drive box 20 and the air deflector 10 easier and simpler, and reduces the difficulty of disassembly and assembly of the two. At the same time, the axial position of the connecting column 26 and the air deflector 10 is limited by the fastener to prevent the first drive box 20 and the air deflector 10 from being separated from each other and affecting the structural stability of the air guide assembly.

[0054] Specifically, the third driving device 34 is drivingly connected to the second end of the air deflector 10 to drive the air deflector 10 to rotate relative to the third rack 33. Optionally, the fastener is a pin or a screw or a bolt.

[0055] Optionally, the second mounting recess is a through hole.

[0056] In this embodiment, the first rack 24 and the second rack 25 are arranged parallel to each other. In this way, when the first driving box 20 is in the first state or the second state, the above arrangement can prevent the first rack 24 and the second rack 25 from causing structural interference and affecting the normal operation of the driving assembly, thereby improving the driving reliability of the driving assembly on the air guide plate 10.

[0057] like Figure 8 and Fig. 9 As shown, the present application further provides an air guide assembly, including an air guide plate 10 and a driving assembly connected to the air guide plate 10, the driving assembly being used to drive the air guide plate 10 to move. The driving assembly is the above-mentioned driving assembly.

[0058] Specifically, when the air deflector 10 is opened, the first rack 24, the second rack 25 and the third rack 33 are pushed out normally, the first rack 24 is meshed and pushed out by the first gear 22, and the second rack 25 is pushed out by the second gear 23. When the air deflector 10 is closed, the second rack 25 is meshed and retracted by the second gear 23, the first rack 24 is meshed and retracted with the first gear 22, and the third rack 33 is retracted normally. In this process, the motors driving the gears of the first drive box 20 and the second drive box 30 are the same, the teeth of the racks are exactly the same, and the motors rotate the same number of times in the same time. In the meshing section of the second rack 25 and the second gear 23, the number of times the second gear 23 needs to rotate will be greater than the number of times the third gear 32 rotates, thereby playing a role in tightening the air deflector 10 to close.

[0059] The present application also provides an air conditioner (not shown) comprising the above-mentioned air guide assembly.

[0060] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0061] The first end of the air deflector is a non-driven side, and the second gear is a pinion gear compared to the first gear, so that a difference in the number of teeth is formed between the first drive box and the second drive box arranged at both ends of the air deflector, and when the operating parameters (such as the rotation speed) of the first drive device and the second drive device are consistent, the rotation angle of the second gear in the first drive box is greater than the rotation angle of the second transmission mechanism in the second drive box. In this way, during the movement of the air deflector to the closed state, the first drive box switches from the first state to the second state, so that the first drive device is connected to the second gear, and the second gear is meshed with the second rack to drive the air deflector to deflect through the second rack and the first rack. In the above process, since the deflection angle of the air deflector driven by the first drive box is greater than the deflection angle of the air deflector driven by the second drive box, the second end of the air deflector is subjected to a tensioning force, and then the air deflector is fully closed on the panel, which solves the problem of the prior art that the air deflector has a gap with the panel when it is closed, which affects the appearance of the air conditioner, improves the sealing and reliability of the air deflector closure, and improves the appearance of the air conditioner.
