Alternatively, the driving element 20 may be a motor, which is in driving connection with the main gear 11, such that the main gear 11 is rotatable in the first direction and the second direction. Alternatively, the main gear 11 and the first driven gear 12 may be in direct contact engagement, the rotation of the main gear 11 drives the rotation of the first driven gear 12, and the first driven gear 12 is fixedly connected to the air deflector 50 of the air conditioner, so that the air deflector 50 can be opened upwards, opened downwards or closed along with the rotation of the first driven gear 12.

In the embodiment of the application, in the process that the air deflector 50 is opened upwards or opened downwards, the movement locus of the air deflector 50 rotates while extending in a translational manner to the outside of the air conditioner, the sizes of the diameters of the main gear 11 and the first driven gear 12, and the lengths of the first rack 31 and the second rack 32 of the rack plate 30 can affect the preset distance that the air deflector 50 extends out of the air conditioner, the extending directions of the first rack 31 and the second rack 32 of the rack plate 30 can determine the direction that the air deflector 50 translates to the outside of the air conditioner, wherein the lengths of the first rack 31 and the second rack 32 are related to the diameters of the gears in the gear assembly 10. The preset distance for the air deflector 50 to horizontally extend out of the air conditioner is a distance for the air deflector 50 to rotate while moving out of the air conditioner. If the diameters of the main gear 11 and the first driven gear 12 are small, so that the distance of the air deflector 50 translating out of the air conditioner cannot meet the requirement of the air deflector 50 rotating, a transmission gear may be arranged between the main gear 11 and the first driven gear 12, so that the distance of the air deflector 50 translating out of the air conditioner meets the preset distance. Alternatively, the number of transmission gears between the main gear 11 and the first driven gear 12 may be set according to a preset distance.

Optionally, the gear assembly 10 further comprises a second driven gear 13, the second driven gear 13 is disposed between the main gear 11 and the first driven gear 12, and the second driven gear 13 is meshed with both the main gear 11 and the first driven gear 12. Thus, as shown in fig. 2, the main gear 11 is rotated by the driving element 20, and the first driven gear 12 is rotated by the driving engagement with the second driven gear 13, so as to drive the air deflector 50 to open upwards, open downwards or close.

Fig. 3-1 and 3-2 are schematic structural views of a main gear 11 of a gear assembly 10 provided in an embodiment of the present application. As shown in fig. 3-2, when the air deflector 50 is closed, the co-toothed portion 114 is located between the first rack 31 and the second rack 32, and the co-toothed portion 114 is in a state to be meshed with the first rack 31 and the second rack 32, so that there is no tooth-off portion between the main gear 11 and the first rack 31 or the second rack 32 when the air deflector 50 is in the closed state, and the main gear 11 is prevented from idling due to no tooth-meshing between the main gear 11 and the first rack 31 or the second rack 32 when the main gear 11 rotates, thereby preventing the air deflector 50 from being unable to move.

Optionally, the main gear 11 further comprises a first tooth 111, the first tooth 111 being located at the first and third circumferential surfaces of the main gear 11, and the first tooth 111 having the same position and the same length at the first and third circumferential surfaces, as shown in fig. 3-1 and 3-2.

Alternatively, the first tooth portion 111 extends from a first end of the common tooth portion 114 to the direction of the second rack bar 32, wherein, when the main gear 11 rotates in the first direction, the first rack bar 31 sequentially meshes with the common tooth portion 114 and the first tooth portion 111 of the main gear 11, and at the same time, the main gear 11 meshes with the second driven gear 13, and the second driven gear 13 meshes with the first driven gear 12, and the air deflector 50 is opened downwards from the closed state.

It is defined that a direction in which the main gear 11 rotates clockwise in fig. 2 is a first direction, and a direction in which the main gear 11 rotates counterclockwise is a second direction.

As shown in fig. 4, fig. 4 is a partial structural diagram of the driving mechanism when the air deflector 50 is opened downward to the maximum angle, the driving element 20 drives the main gear 11 to rotate in the first direction, that is, the main gear 11 rotates clockwise, the first rack 31 sequentially meshes with the co-tooth portion 114 and the first tooth portion 111 of the main gear 11, and at the same time, the main gear 11 meshes with the second driven gear 13, and the second driven gear 13 meshes with the first driven gear 12 to rotate, so that the first driven gear 12 drives the air deflector 50 to be opened downward from the closed state. During the downward opening of the air deflection plate 50, only the main gear 11 is engaged with the first rack 31, and neither the first driven gear 12 nor the second driven gear 13 is engaged with the first rack 31 and the second rack 32. Alternatively, the second driven gear 13 may be prevented from being engaged with the first and second racks 31 and 32 by adjusting the size of the second driven gear 13. Alternatively, the first driven gear 12 may be prevented from meshing with the first and second racks 31 and 32 by adjusting the positions of the first driven gear 12 and the rack plate 30, or the size of the first driven gear 12.

Optionally, the main gear 11 further comprises a second tooth portion 112, the second tooth portion 112 is located on a second circumferential surface and a third circumferential surface of the main gear 11, and the second tooth portion 112 has the same position and the same length on the second circumferential surface and the third circumferential surface.

Alternatively, the second tooth portion 112 extends from the second end of the co-tooth portion 114 to the direction of the first rack 31, wherein, when the main gear 11 rotates in the second direction, the second tooth bar 32 sequentially meshes with the co-tooth portion 114 and the second tooth portion 112 of the main gear 11, and at the same time, the main gear 11 meshes with the second driven gear 13, and the second driven gear 13 meshes with the first driven gear 12, and the air deflector 50 is opened upwards from the closed state.

As shown in fig. 5, fig. 5 is a partial structural view of the driving mechanism when the air deflector 50 is opened upward to the maximum angle, the driving element 20 drives the main gear 11 to rotate in the second direction, i.e. the main gear 11 rotates counterclockwise, the second rack 32 sequentially meshes with the cogged portion 114 and the second cogged portion 112 of the main gear 11, and at the same time, the main gear 11 meshes with the second driven gear 13, and the second driven gear 13 meshes with the first driven gear 12 to rotate, so that the first driven gear 12 drives the air deflector 50 to open upward from the closed state. During the upward opening of the air deflector 50, only the main gear 11 is engaged with the second rack 32, and neither the first driven gear 12 nor the second driven gear 13 is engaged with the first rack 31 and the second rack 32.

Optionally, the main gear 11 further comprises a third tooth portion 113, the third tooth portion 113 is located on a third circumference of the main gear 11, and the third tooth portion 113 is disposed between the first tooth portion 111 and the second tooth portion 112. When the air deflector 50 is opened upwards or downwards from the closed state, the third tooth portion 113 functions to be in transmission engagement with the second driven gear 13, and if the third tooth portion 113 is a non-tooth portion, the main gear 11 cannot be kept in transmission engagement with the second driven gear 13 all the time during the rotation process, that is, the air deflector 50 cannot be rotated to the maximum angle.

Alternatively, the arc length of the first tooth portion 111 and the arc length of the second tooth portion 112 of the main gear 11 are the same, and the length of the first rack 31 is required to satisfy the meshing requirement of the first tooth portion 111 of the main gear 11, and the length of the second rack 32 is required to satisfy the meshing requirement of the second tooth portion 112 of the main gear 11. The vertical distance between the first rack 31 and the second rack 32 determines the arc length of the common tooth portion 114 of the main gear 11. Thus, the maximum angle at which the air deflection plate 50 opens upwardly is equal to the maximum angle at which the air deflection plate 50 opens downwardly.

Alternatively, the arc length of the first tooth portion 111 of the main gear 11 and the arc length of the second tooth portion 112 may also be different, and in the case that the length of the first rack 31 meets the meshing requirement of the first tooth portion 111 of the main gear 11 and the length of the second rack 32 meets the meshing requirement of the second tooth portion 112 of the main gear 11, the maximum angle at which the air deflector 50 opens upward is different from the maximum angle at which the air deflector 50 opens downward.

Alternatively, both ends of the first side of the gear cover plate 40 are provided with the sliding posts 41, and the first side of the gear cover plate 40 is the side of the fixed gear assembly 10. The number of the sliding columns 41 arranged at the first end of the gear cover plate 40 is the same as that of the sliding sleeves arranged in the first slide way 33, and the second end of the gear cover plate 40 is arranged; the number of slide posts 41 is the same as the number of slide sleeves provided in the second runner 34. Optionally, the first end of the gear cover 40 is provided with a first sliding column 411 and a second sliding column 412, the first sliding column 411 is installed in the first sliding sleeve 351 of the first slideway 33, and the second sliding column 412 is installed in the second sliding sleeve 352 of the first slideway 33. Optionally, the second end of the gear cover plate 40 is disposed on the third sliding column 413 and the fourth sliding column 414, the third sliding column 413 is disposed in the third sliding sleeve 353 of the second slideway 34, and the fourth sliding column 414 is disposed in the fourth sliding sleeve 354 of the second slideway 34. With the air deflector 50 closed, the first sliding column 411 is located at the first end of the first slideway 33 and the third sliding column 413 is located at the first end of the second slideway 34.
