As shown in fig. 1-5, embodiments of the present disclosure provide a drive assembly for an air deflection panel that includes a gear 10 and a rack bar 20.

The rack connecting plate 20 is used for connecting with the air deflector 30, the rack connecting plate 20 includes a first rack 214 and a second rack 215, the gear 10 can be meshed with the first rack 214 or the second rack 215 to drive the first rack 214 or the second rack 215 to rotate, when the gear 10 drives the first rack 214, the first rack 214 rotates with the first rotation center as an axis, so that the air deflector 30 is in an upward opening state; when the gear 10 drives the second rack 215, the second rack 215 rotates around the second rotation center as an axis, so that the air deflector 30 is in a downward opening state.

It can be understood that the first rack 214 and the second rack 215 are both arc-shaped structures, the gear 10 can be meshed with the first rack 214 and also can be meshed with the second rack 215, and when the gear 10 drives the first rack 214 to rotate, the gear 10 is not meshed with the second rack 215; when the gear 10 drives the second rack 215 to rotate, the gear 10 is not engaged with the first rack 214. By controlling the rotation direction and the rotation number of the gear 10, the gear 10 can drive only one of the first rack 214 and the second rack 215.

The first rack 214 is mainly used for enabling the air deflector 30 to be in an upward opening state, the second rack 215 is mainly used for enabling the air deflector 30 to be in a downward opening state, the rack connecting plate 20 mainly plays a role in transmission, and as the first rack 214 and the second rack 215 are installed on the rack connecting plate 20 and the rack connecting plate 20 is connected with the air deflector 30, when the first rack 214 or the second rack 215 moves under the driving of the gear 10, the air deflector 30 will also move along with the first rack 214 or the second rack 215.

As an example, the first rack 214 and the second rack 215 are both arc-shaped structures, the teeth of the first rack 214 and the second rack 215 are both disposed on the convex surface of the arc-shaped structures, the teeth of the first rack 214 and the second rack 215 are both disposed toward the gear 10, a first end of the first rack 214 is close to a first end of the second rack 215, and a second end of the first rack 214 is far from a second end of the second rack 215. The pinion 10 is located at first ends of the first and second racks 214 and 215 in an initial state while being engaged with the first and second racks 214 and 215, as shown in fig. 1. At this time, the air deflector is in a closed state. When the first rack 214 or the second rack 215 needs to be driven by the gear 10, the gear 10 is rotated in the corresponding driving direction and is disengaged from the other rack, and when the air deflector 30 needs to be closed or the air deflector 30 needs to be opened in the other direction, the gear 10 is rotated in the direction opposite to the initial driving direction.

By adopting the driving assembly for the air deflector 30 provided by the embodiment of the disclosure, the first rack 214 for opening the air deflector 30 upwards and the second rack 215 for opening the air deflector 30 downwards are integrated on one rack connecting plate 20, the gear 10 can drive the first rack 214 or the second rack 215, when the gear 10 drives the first rack 214, the air deflector 30 is in an upwards opening state, and when the gear 10 drives the second rack 215, the air deflector 30 is in a downwards opening state, so that the air deflector 30 can realize two states of upwards opening and downwards opening by only adopting one set of driving mechanism, and can rotate at a large angle, and can be closed at the same time. Alternatively, the number of gears 10 is 1. The driving assembly for the air deflector provided by the embodiment of the disclosure has a small number of moving mechanisms, reduces the probability of the movement fault of the air deflector, and improves the reliability of the movement of the air deflector 30.

Optionally, the first center of rotation is different from the second center of rotation.

It can be understood that the arc centers of the first rack 214 and the second rack 215 are different, and when the gear 10 drives the first rack 214, the first rack 214 rotates around its arc center, i.e. the first rotation center, and drives the air deflector body 31 to rotate, and the air deflector 30 is in an upward opening state at this time; when the gear 10 drives the second rack 215, the second rack 215 rotates around the arc center thereof, i.e. the second rotation center, and drives the air guiding plate body 31 to rotate, and the air guiding plate 30 is in a downward opening state. The first rotation center and the second rotation center may be understood as virtual axes.

As shown in fig. 4, optionally, the first and second racks 214 and 215 are symmetrically disposed on the rack attachment plate 20.

It can be understood that the maximum arc length of the first rack 214 driven by the gear 10 is equal to the maximum arc length of the second rack 215 driven by the gear 10, and the maximum opening angle of the air deflector 30 opening upwards is the same as the maximum opening angle of the air deflector 30 opening downwards.

Alternatively, when the gear 10 is located on the perpendicular bisector of the connecting line of the arc centers of the first rack 214 and the second rack 215, the air deflector 30 is in the closed state, as shown in fig. 1.

It can be understood that, since the position of the gear 10 is not changed, when the gear 10 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 will move along with the rotation of the rack connecting plate 20, and the arc center connecting line and the perpendicular bisector of the first rack 214 and the second rack 215 will also be in a moving state, and only when the rack connecting plate 20 returns to the initial position, i.e., the gear 10 is engaged with both the first rack 214 and the second rack 215, the air deflector 30 is in a closed state, and when the gear 10 is engaged with only one of the racks, the air deflector will be in an open state, as shown in fig. 1-3.

Alternatively, a part of the circumferential surface of the gear 10 is provided with teeth.

It can be understood that: the working face of the gear 10 comprises both toothed and toothless portions.

As an example, the arc length of the toothed portion is related to the arc length of the first and second racks 214 and 215, which is less than or equal to the arc length of the first and second racks, optionally the toothed portion of the gear 10 is provided with consecutive teeth; optionally, the area of the non-toothed portion is larger than the area of the toothed portion.

As an example, the toothed portion and the non-toothed portion are respectively located on two sides of the working surface of the gear 10, and in the initial state, the non-toothed portion of the gear 10 faces the gap between the first rack 214 and the second rack 215, as shown in fig. 1, when the gear 10 starts to drive the first rack 214, the toothed portion is engaged with the first rack 214, and the non-toothed portion faces the second rack 215, and the gear 10 is not engaged with the first rack 214 and the second rack 215 at the same time, so as to avoid the seizing.

Optionally, the first rack 214 extends in an arc toward one end of the rack attachment plate 20; the second rack 215 extends in an arc toward the other end of the rack attachment plate 20, as shown in fig. 4.

The rack connecting plate 20 can respectively rotate by the arc center of the first rack 214 and the arc center of the second rack 215, and because the arc centers of the first rack 214 and the second rack 215 are both located at the side part of the rack connecting plate 20, compared with a structure that the rotation center is located at the middle part, the rack connecting plate 20 and the air deflector 30 connected with the rack connecting plate can rotate at a large angle, so that large-area air supply is realized.

Alternatively, the rack connecting plate 20 includes a rack portion 21, and a connecting portion 22 connected to the air deflection plate 30, wherein the rack portion 21 is a U-shaped structure that is open to the outside, the U-shaped structure includes a bottom portion 213, and a first side portion 211 and a second side portion 212 that extend outward along the bottom portion 213, the first rack 214 is disposed on the first side portion 211, and the second rack 215 is disposed on the second side portion 212.

It can be understood that the rack attachment plate 20 mainly includes two portions, a rack portion 21 and a connecting portion 22, wherein the rack portion 21 is a main component which is engaged with the pinion 10, and the connecting portion 22 is a main component which is connected with the air deflection plate 30. The initial position of the gear 10 is located at the bottom 213 of the U-shaped structure, when the gear 10 drives the first rack 214, the rack connecting plate 20 rotates around the arc center of the first rack 214 and drives the air deflector body 31 to rotate, the air deflector 30 is in an upward opening state, when the gear 10 drives the second rack 215, the rack connecting plate 20 rotates around the arc center of the second rack 215 and drives the air deflector body 31 to rotate, and the air deflector 30 is in a downward opening state.

As an example, the entire circumference of the gear 10 is provided with teeth, and the bottom 213 of the rack connecting plate 20 is not provided with teeth, so that the gear 10 and the rack portion 21 are prevented from being stuck to affect normal rotation fit.

As another example, the bottom 213 of the U-shaped structure is not provided with teeth. A part of the circumferential surface of the gear 10 is provided with teeth, the working surface of the gear 10 comprises a toothed part and a non-toothed part, the toothed part and the non-toothed part are respectively positioned at two sides of the working surface of the gear 10, in an initial state, the non-toothed part of the gear 10 faces the bottom 213, when the gear 10 starts to drive the first rack 214, the toothed part is meshed with the first rack 214, the non-toothed part faces the second rack 215, and the gear 10 is not meshed with the second rack 215; when the gear 10 starts to drive the second rack 215, the toothed part is engaged with the second rack 215, the non-toothed part faces the first rack 214, and the gear 10 is not engaged with the first rack 214; the gear 10 is not meshed with the first rack 214 and the second rack 215 at the same time, so that the situation that the rack connecting plate 20 is blocked is avoided.

As another example, the bottom 213 of the U-shaped structure is provided with teeth for performing a buffering process of rack-fitting switching. The working surface of the gear 10 comprises a toothed part and a non-toothed part, the toothed part and the non-toothed part are respectively positioned at two sides of the working surface of the gear 10, in an initial state, the non-toothed part of the gear 10 faces the bottom 213, when the gear 10 starts to drive the first rack 214, the toothed part is meshed with the first rack 214, the non-toothed part faces the second rack 215, the gear 10 is not meshed with the second rack 215, and the air deflector 30 is in an upward opening state; when the gear 10 starts to drive the second rack 215, the toothed portion is engaged with the second rack 215, the non-toothed portion faces the first rack 214, the gear 10 is not engaged with the first rack 214, and the air deflector 30 is in a downward opening state.

The gear 10 is not meshed with the first rack 214 and the second rack 215 at the same time, so that the situation that the rack connecting plate 20 is blocked is avoided.

It can be understood that, when the gear 10 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 and the air deflector 30 will also rotate along with the gear, and in order to prevent the movement tracks of the rack connecting plate 20 and the air deflector 30 from deviating and affect the normal use of the air conditioner, guide structures matched with each other are arranged on the rack connecting plate 20 and the air deflector bracket 40 to guide the rotation of the rack connecting plate 20 and the air deflector 30, and the rack connecting plate 20 and the air deflector 30 are installed on the indoor unit of the air conditioner.

As an example, the racking plate 20 is a sliding or rolling fit with the air deflection bracket 40. The first guiding structure 2211 is a sliding block or a rolling ball, and the second guiding structure 41 is a sliding rail. Alternatively, the first guiding structure 2211 may be configured as a sliding rail, and the second guiding structure 41 may be configured as a sliding block or a rolling ball.

Similarly, when the air deflector 30 is required to be in a downward opening state, the gear 10 is rotated from an initial state in a second direction, in the process, the gear 10 is disengaged from the first rack 214 and starts to drive the second rack 215, at this time, the second rack 215 rotates around a second rotation center as an axis to drive the air deflector 30 to perform a downward opening action, and the downward opening size of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 10 or the displacement of the gear 10 on the second rack 215; when the air deflector 30 needs to be closed, the gear 10 is rotated in the first direction, the rack connecting plate 20 is driven to return to the initial position by the second rack 215, and at this time, the gear 10 is meshed with the first ends of the first rack 214 and the second rack 215 at the same time; when the air deflector 30 needs to be switched from the downward opening state to the upward opening state, the gear 10 is firstly rotated in the first direction to return the rack connecting plate 20 to the initial position, then the gear 10 is continuously rotated in the first direction to be disengaged from the second rack 215, and the first rack 214 is started to be driven, the first rack 214 rotates around the first rotation center as an axis to drive the air deflector 30 to perform the upward opening action, and the size of the upward opening of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 10 or the displacement of the gear 10 on the first rack 214.

In the present application, the first rack 214 for opening the air deflector 30 upwards and the second rack 215 for opening the air deflector 30 downwards are integrated on one rack connection plate 20, the gear 10 can drive the first rack 214 or the second rack 215, when the gear 10 drives the first rack 214, the air deflector 30 is in an upwards opening state, and when the gear 10 drives the second rack 215, the air deflector 30 is in a downwards opening state, so that the present application can only adopt one set of driving mechanism to realize two states of opening the air deflector 30 upwards and opening the air deflector 30 downwards, and can realize closing of the air deflector 30 at the same time. The driving assembly for the air deflector and the air conditioner indoor unit provided by the embodiment of the disclosure have the advantages that the number of the moving mechanisms for driving the air deflector to move is small, the probability of the movement fault of the air deflector is reduced, and the movement reliability of the air deflector 30 is improved.

In addition, because the air deflector 30 is connected with the rack connecting plate 20, the air deflector 30 can rotate at a large angle through a set of driving mechanism under the matching of the gear 10 and the rack connecting plate 20, and no obvious gap is generated to influence the use of the air conditioner.
