As shown in fig. 1-5, embodiments of the present disclosure provide a drive mechanism for an air deflection plate 50.

In some embodiments, the drive mechanism for the air deflection plate 50 includes: the gear assembly 10 is used for driving the air deflector 50 to open or close; the drive element 20 is used to drive the gear assembly 10; the rack plate 30 is provided with a first rack 31 and a second rack 32 engaged with the gear assembly 10, wherein the first rack 31 and the second rack 32 are arranged in a staggered manner, and when the gear assembly 10 is engaged with the first rack 31, the air deflector 50 is opened downward, and when the gear assembly 10 is engaged with the second rack 32, the air deflector 50 is opened upward.

Alternatively, the driving element 20 may be a motor capable of bi-directionally driving the gear assembly 10 to rotate, the motor being in driving connection with the gear assembly 10, the motor being capable of driving the gear assembly 10 to rotate in either the first direction or the second direction.

In the embodiment of the present application, as shown in fig. 1, the first rack 31 is disposed on the first rack plate surface, the second rack 32 is disposed on the second rack plate surface, the first rack 31 and the second rack 32 of the rack plate 30 are disposed in a staggered manner, the staggered manner is that there is no rack at the position of the first rack plate surface corresponding to the second rack plate surface, the first rack 31 and the second rack 32 are located at different heights and different sides of the inner side surface of the rack plate 30, and both extend in the direction in which the air guide plate 50 is horizontally moved out of the air conditioner. Thus, when the gear assembly 10 rotates in the first direction or the second direction, the gear assembly 10 engages with only one rack of the rack plate 30. Alternatively, the first rack 31 is located at a lower portion of the first rack plate and the second rack 32 is located at an upper portion of the second rack plate.

In the embodiment of the present application, the driving mechanism for the air deflector 50 includes a gear assembly 10, a driving element 20, and a rack plate 30, wherein the gear assembly 10 is used for driving the air deflector 50 to open or close, the driving element 20 is used for driving the gear assembly 10, the rack plate 30 is provided with a first rack 31 and a second rack 32 which are engaged with the gear assembly 10, and the first rack 31 and the second rack 32 are arranged in a staggered manner, when the gear assembly 10 is engaged with the first rack 31 of the rack plate 30, the air deflector 50 is opened downward, and when the gear assembly 10 is engaged with the second rack 32, the air deflector 50 is opened upward. The driving element 20 can rotate the gear assembly 10 in the first direction or the second direction, and the first rack 31 and the second rack 32 of the rack plate 30 are arranged in a staggered manner, so that only one rack of the rack plate 30 can be meshed with the gear assembly 10 when the gear assembly 10 rotates in the first direction or the second direction. Thus, when the gear assembly 10 rotates in the first direction, the gear assembly 10 engages with the first rack 31 of the rack plate 30, so that the air deflector 50 is opened downward from the closed state, and at this time, when the gear assembly 10 rotates in the second direction and still engages with the first rack 31 of the rack plate 30, the air deflector 50 returns to the closed state from the downward opened state. When the gear assembly 10 rotates in the second direction, the gear assembly 10 engages with the second rack 32 of the rack plate 30 to open the air deflection plate 50 upward from the closed state, and at this time, when the gear assembly 10 rotates in the first direction and still engages with the second rack 32 of the rack plate 30, the air deflection plate 50 returns to the closed state from the upward open state. Thus, one air deflector 50 can be opened upwards, opened downwards or closed through one set of driving mechanism, the driving mechanism is simple in structure, and the failure rate of the driving mechanism is reduced.

Optionally, the gear assembly 10 comprises: a main gear 11 and a first driven gear 12, the main gear 11 being in driving connection with a driving element 20; the first driven gear 12 is used for being fixedly connected with an air deflector 50 of the air conditioner and driving the air deflector 50 to be opened upwards, opened downwards or closed.

Alternatively, the driving element 20 may be a bi-directional driving motor, which is drivingly connected to 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 in the translational manner to the outside of the air conditioner, and 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 predetermined distance that the air deflector 50 extends out of the air conditioner is a distance that the air deflector 50 can 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 moving out of the air conditioner cannot meet the requirement of rotation of the air deflector 50, 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 extending 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. 1, 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. 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 no gear-disengaging portion exists 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 gear-engaging portion 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 incapable of moving.

Optionally, the main gear 11 further comprises a first tooth 111, the first tooth 111 is located on the first and third circumferential surfaces of the main gear 11, and the first tooth 111 has the same position and the same length on 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 view 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 a first direction, that is, the main gear 11 rotates clockwise, the first rack 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 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 meshing with the first rack 31 and the second rack 32 by adjusting the size of the second driven gear 13. Alternatively, the first driven gear 12 may be prevented from being engaged 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 rack 32 is sequentially meshed with the co-tooth portion 114 and the second tooth portion 112 of the main gear 11, and simultaneously, the main gear 11 is meshed with the second driven gear 13 and the second driven gear 13 is meshed with the first driven gear 12 to rotate, 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, main gear 11 further includes a third tooth portion 113, third tooth portion 113 is located on a third circumferential surface of main gear 11, and third tooth portion 113 is disposed between first tooth portion 111 and second tooth portion 112, as shown in fig. 3-1. 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 in the rotation process, that is, the air deflector 50 cannot be rotated to the maximum angle.

As shown in fig. 3-1 and 3-2, main gear 11 includes a cogged portion 114, a first tooth portion 111, a second tooth portion 112, and a third tooth portion 113, wherein main gear 11 has 3 circumferential surfaces, i.e., a first circumferential surface, a second circumferential surface, and a third circumferential surface. The cogged portions 114 of the main gear 11 are distributed side by side on the 3 peripheral surfaces of the main gear 11, and the teeth between the first rack 31 and the second rack 32 are the cogged portions 114 of the main gear 11 when the air deflector 50 is in the closed state. The first teeth 111 are located on the first and third circumferential surfaces of the main gear 11, and the first teeth 111 are connected to the first ends of the co-teeth 114, and the first teeth 111 have the same position and the same length on the first and third circumferential surfaces. The second tooth portion 112 is located on the second circumferential surface and the third circumferential surface of the main gear 11, and the second tooth portion 112 is connected to the second end of the common tooth portion 114, and the second tooth portion 112 has the same position and the same length on the second circumferential surface and the third circumferential surface. Third tooth 113 is located on the third circumferential surface of main gear 11 and between first tooth 111 and second tooth 112.

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, the first rack 31 and the second rack 32 are both linear racks.

The first rack 31 and the second rack 32 of the rack plate 30 are used for mounting the gear assembly 10 of the air conditioner, and the extending directions of the first rack 31 and the second rack 32 affect the moving track of the wind deflector 50 which extends outwards from the air conditioner. The first rack 31 and the second rack 32 are both linear racks, so that the motion locus of the wind deflector 50 extending out from the air conditioner is also linear, that is, the wind deflector 50 can rotate along the extending direction of the first rack 31 and the second rack 32, and the length of the first rack 31 and the second rack 32 and the gear diameter of the gear set can influence the distance that the wind deflector 50 extends out from the air conditioner.

As shown in fig. 2, the first rack 31 and the second rack 32 of the rack plate 30 are arranged in parallel, the first rack plate surface and the second rack plate surface are also arranged in parallel, the first rack 31 is located at the lower portion of the first rack plate surface, and the second rack 32 is located at the upper portion of the second rack plate surface. Alternatively, the first rack 31 is located on the upper portion of the first rack plate surface, and the second rack 32 is located on the lower portion of the second rack plate surface, that is, the first rack 31 and the second rack 32 are arranged in a staggered manner. In the embodiment of the present application, one side of the rack plate 30 is generally fixed to the housing 60 of the air conditioner, the lower portions of the first rack plate surface and the second rack plate surface are the positions where the rack plate 30 is close to the air conditioner housing 60, and the upper portions of the first rack plate surface and the second rack plate surface are the positions where the rack plate 30 is far away from the air conditioner housing 60.
