The surface of the first link 10 facing the first gear 50 is recessed to form a first concave portion 102, and the surface of the second link 20 facing the second gear 60 is projected toward the second gear 60 to form a second convex portion 202.

The first concave portion 102 is provided on the first link 10, the second convex portion 202 is provided on the second link 20, and when the damper 30 is in the closed position, the first concave portion 102 corresponds to the second convex portion 202, that is, the shapes of the first link 10 and the second link 20 are different. This enables the first link 10 and the second link 20 to have different telescopic movement speeds when the first gear 50 is engaged with the first concave portion 102 and the second gear 60 is engaged with the second convex portion 202. The first connecting rod 10 and the second connecting rod 20 are movably connected with the air deflector 30, and when the first connecting rod 10 and the second connecting rod 20 have different telescopic movement speeds, the air deflector 30 can be positioned at a plurality of different air guiding positions, so that a plurality of different air outlet modes are realized.

Wherein, in the first open position, the air guiding surface 301 of the air guiding plate 30 faces downwards, so as to realize downward blowing of hot air; in the second open position, the air guiding surface 301 of the air guiding plate 30 faces upwards, so that cold air is blown upwards, and cold air is prevented from being blown directly.

The second curved portion 205 further includes a second concave portion 203, where the second concave portion 203 and the second convex portion 202 are sequentially disposed along the direction in which the second connecting rod 20 extends out of the air duct, that is, the second convex portion 202 is located between the second concave portion 203 and the air deflector 30, and second gear teeth 204 are disposed on the second concave portion 203. Wherein, when the air deflector 30 is at the closed position, the first convex portion 103 corresponds to the second concave portion 203, so that the first gear 50 is meshed with the first convex portion 103, and the second gear 60 is meshed with the second concave portion 203, the first link 10 and the second link 20 can have different movement speeds.

The surface of the first link 10 facing the first gear 50 protrudes toward the first gear 50 to form a first convex portion 103, and the surface of the second link 20 facing the second gear 60 is recessed to form a second concave portion 203.

As in fig. 1 and 2, when the air deflector 30 is in the closed position, the first concave portion 102 corresponds to the second convex portion 202, and the first convex portion 103 corresponds to the second concave portion 203, so that the first link 10 and the second link 20 have different shapes at the corresponding positions.

During the opening process of the air deflector 30, the first gear 50 is engaged with the first concave portion 102, the second gear 60 is engaged with the second convex portion 202, then the first gear 50 is engaged with the first convex portion 103, and the second gear 60 is engaged with the second concave portion 203. The first concave part 102, the second convex part 202, the second concave part 203 and the first convex part 103 are arranged, so that the first connecting rod 10 and the second connecting rod 20 have different shapes, when the first connecting rod 10 is meshed with the first gear 50 and the second connecting rod 20 is meshed with the second gear 60, the first connecting rod 10 and the second connecting rod 20 can have different movement speeds, the first connecting rod 10 and the second connecting rod 20 are movably connected with the air deflector 30, the differential movement of the first connecting rod 10 and the second connecting rod 20 can be realized, the air deflector 30 can have various air guiding positions, and the air conditioner can realize various air outlet modes.

Both the first concave portion 102 and the first convex portion 103 are driven by the first gear 50, the distance between the first concave portion 102 and the rotational axis of the first gear 50 when the first concave portion 102 is meshed with the first gear 50 is greater than the distance between the first convex portion 103 and the rotational axis of the first gear 50 when the first convex portion 103 is meshed with the first gear 50, the radius of the first gear 50 where the first concave portion 102 is meshed with is greater than the radius of the first gear 50 where the first convex portion 103 is meshed, and the movement speed of the first link 10 when the first concave portion 102 is meshed with the first gear 50 is greater than the movement speed of the first link 10 when the first convex portion 103 is meshed with the first gear 50 when the angular speeds of the first gear 50 are equal.

The second convex portion 202 and the second concave portion 203 are both driven by the second gear 60, the distance between the second convex portion 202 and the rotation axis of the second gear 60 when the second convex portion 202 is meshed with the second gear 60 is smaller than the distance between the second concave portion 203 and the rotation axis of the second gear 60 when the second concave portion 203 is meshed with the second gear 60, the radius of the second gear 60 where the second convex portion 202 is meshed with is smaller than the radius of the second gear 60 where the second concave portion 203 is meshed, and the movement speed of the second link 20 when the second convex portion 202 is meshed with the second gear 60 is smaller than the movement speed of the second link 20 when the second concave portion 203 is meshed with the second gear 60 when the angular speeds of the second gear 60 are equal.

In a specific embodiment, the movement speed of the first link 10 when the first concave portion 102 is engaged with the first gear 50 is greater than the movement speed of the second link 20 when the second convex portion 202 is engaged with the second gear 60, and the movement speed of the first link 10 when the first convex portion 103 is engaged with the first gear 50 is less than the movement speed of the second link 20 when the second concave portion 203 is engaged with the second gear 60, so that the wind deflector 30 can be turned in different directions.

Optionally, the first connecting rod 10 is further provided with a first precursor portion 101, the first concave portion 102 and the first precursor portion 101 are sequentially arranged along the direction that the first connecting rod 10 extends out of the air duct, that is, the first precursor portion 101 is located between the first concave portion 102 and the air deflector 30, and the first precursor portion 101 is provided with first gear teeth 104; the second connecting rod 20 is also provided with a second precursor part 201, the second convex part 202 and the second precursor part 201 are sequentially arranged along the direction that the second connecting rod 20 extends out of the air duct, namely, the second precursor part 201 is positioned between the second convex part 202 and the air deflector 30, and the second precursor part 201 is provided with second gear teeth 204; wherein the first precursor portion 101 and the second precursor portion 201 correspond when the air deflector 30 is in the closed position.

The absolute value of the difference between the movement speed of the first link 10 when the first precursor 101 is engaged with the first gear 50 and the movement speed of the second link 20 when the second precursor 201 is engaged with the second gear 60 is smaller than the preset difference, that is, the movement speed of the first link 10 when the first precursor 101 is engaged with the first gear 50 and the movement speed of the second link 20 when the second precursor 201 is engaged with the second gear 60 are close to each other.

When the movement speed of the first connecting rod 10 is equal to the movement speed of the second connecting rod 20 when the first precursor 101 is meshed with the first gear 50 and the second precursor 201 is meshed with the second gear 60, the air deflector 30 is pushed out in a direction away from the air outlet 1001, and no overturning movement exists, so that the air deflector 30 can be prevented from overturning and interfering with the side wall of the air duct or the housing 100.

When the absolute value of the difference between the movement speed of the first link 10 when the first precursor 101 is meshed with the first gear 50 and the movement speed of the second link 20 when the second precursor 201 is meshed with the second gear 60 is greater than zero and less than the preset difference, the air deflector 30 is pushed out in a direction away from the air outlet 1001 while turning over, and because the air deflector 30 is pushed out in a direction away from the air outlet 1001 while turning over, interference with the side wall of the air duct or with the housing 100 during movement of the air deflector 30 can be avoided.

The absolute value of the difference between the movement speed of the first connecting rod 10 when the first concave portion 102 is meshed with the first gear 50 and the movement speed of the second connecting rod 20 when the second convex portion 202 is meshed with the second gear 60 is larger than the preset difference, so that the speed difference between the first connecting rod 10 and the second connecting rod 20 is larger when the first concave portion 102 is meshed with the first gear 50 and the second convex portion 202 is meshed with the second gear 60, the overturning of the air deflector 30 can be realized, and various air guiding positions of the air deflector 30 can be realized.

The absolute value of the difference between the movement speed of the first connecting rod 10 when the first convex part 103 is meshed with the first gear 50 and the movement speed of the second connecting rod 20 when the second concave part 203 is meshed with the second gear 60 is larger than the preset difference, so that the speed difference between the first connecting rod 10 and the second connecting rod 20 is larger when the first convex part 103 is meshed with the first gear 50 and the second concave part 203 is meshed with the second gear 60, the turnover of the air deflector 30 can be realized, and various air guiding positions of the air deflector 30 can be realized.

The bending degree of the first precursor portion is different from that of the first curved portion, for example, when the first precursor portion is straight, the first precursor portion is not bent; for another example, the first precursor portion is curved, but the curvature of the first precursor portion is greater or less than the curvature of the first curved portion.

The bending degree of the first precursor part is different from that of the first curve part, so that when the angular speed of the first gear is a certain value, the movement condition of the first connecting rod when the first gear is meshed with the first precursor part is different from that when the first gear is meshed with the first curve part, and the air outlet modes can be multiple.

In a specific embodiment, at least one of the first precursor portion 101 and the second precursor portion 201 is straight, and for example, the first precursor portion 101 and the second precursor portion 201 are curved, but the curvature of the first precursor portion 101 is smaller than the curvature of the first concave portion 102, and the curvature of the second precursor portion 201 is smaller than the curvature of the second convex portion 202. The shapes of the first gear 50 and the second gear 60 are conveniently designed such that the absolute value of the difference between the movement speed of the first link 10 when the first precursor 101 is engaged with the first gear 50 and the movement speed of the second link 20 when the second precursor 201 is engaged with the second gear 60 is smaller than a preset difference.

Optionally, the bending degree of the first precursor part is different from the bending degrees of the first convex part and the first concave part, so that more air outlet modes can be realized.

Optionally, the second precursor portion and the second curved portion are sequentially arranged along the length direction of the second connecting rod, and the bending degrees of the second precursor portion and the second curved portion are different, so that the bending degree of the first precursor portion corresponds to the bending degree of the second precursor portion, and the bending degree of the first curved portion corresponds to the bending degree of the second curved portion, so that the air deflector has various air guiding positions.

Optionally, the bending degree of the second precursor portion is different from the bending degree of the second convex portion and the bending degree of the second concave portion, so that the bending degree of the first precursor portion corresponds to the bending degree of the second precursor portion, the bending degree of the first concave portion corresponds to the bending degree of the second convex portion, and the bending degree of the first convex portion corresponds to the bending degree of the second concave portion, so that the air deflector has various air guiding positions.

The first gear is meshed with the first precursor part, the movement speed difference of the first connecting rod and the second connecting rod is different from that of the first gear meshed with the first curve part and the movement speed difference of the first connecting rod and the second connecting rod is different from that of the second gear meshed with the second curve part when the second gear meshed with the second curve part, so that various air guiding positions of the air deflector are realized, and various air outlet modes are realized.

Alternatively, the first gear 50 and the second gear 60 are both non-circular, so that the first gear 50 can be engaged with the first precursor portion 101, the first recess 102, and the first protrusion 103, and the second gear 60 can be engaged with the second precursor portion 201, the second protrusion 202, and the second recess 203.

As shown in fig. 3 and 4, the first gear 50 has different radii at the meshing positions with the first precursor 101, the first recess 102, and the first protrusion 103, respectively; the second gear 60 has different radii at the engagement points with the second precursor portion 201, the second protrusion 202, and the second recess 203.

Alternatively, the rotation axes of the first gear 50 and the second gear 60 coincide, so that the first gear 50 and the second gear 60 can be driven by one power source 40, and the structure of the driving mechanism can be simplified.
