The first protrusion 202 and the second recess 203 are both driven by the second gear 60, the distance between the first protrusion 202 and the rotational axis of the second gear 60 when the first protrusion 202 is meshed with the second gear 60 is smaller than the distance between the second recess 203 and the rotational axis of the second gear 60 when the second recess 203 is meshed with the second gear 60, the radius of the second gear 60 where the first protrusion 202 is meshed with is smaller than the radius of the second gear 60 where the second recess 203 is meshed, and the movement speed of the second link 20 when the first protrusion 202 is meshed with the second gear 60 is smaller than the movement speed of the second link 20 when the second recess 203 is meshed with the second gear 60 when the angular speeds of the second gears 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 first convex portion 202 is engaged with the second gear 60, and the movement speed of the first link 10 when the second 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 first 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 first 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.
The air deflector is opened while passing through the extended position, the first open position and the second open position in sequence. In the extended position, the air guiding surface of the air guiding plate faces the air outlet.
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 movement speed of the second precursor 201 is meshed with the second gear 60, the air deflector 30 is pushed out towards the 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 shell 100, and the air deflector reaches the extending position.
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 towards the direction away from the air outlet 1001 while turning over, and the air deflector 30 is pushed out towards the direction away from the air outlet 1001 while turning over, so that interference with the side wall of the air duct or with the housing 100 during movement of the air deflector 30 can be avoided, and the air deflector reaches the extended position.
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 first convex portion 202 is meshed with the second gear 60 is larger than the preset difference, so that the difference between the movement speed of the first connecting rod 10 and the movement speed of the second connecting rod 20 when the first concave portion 102 is meshed with the first gear 50 and the movement speed of the first convex portion 202 is meshed with the second gear 60 is larger, 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 second 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 difference between the movement speed of the first connecting rod 10 and the movement speed of the second connecting rod 20 when the second convex part 103 is meshed with the first gear 50 and the movement speed of the second concave part 203 is meshed with the second gear 60 is larger, the turnover of the air deflector 30 can be realized, and various air guiding positions of the air deflector 30 can be realized.
For example, at least one of the first precursor portion 101 and the second precursor portion 201 is straight, and for example, both 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 first 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.
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 concave portion 102, and the second convex portion 103, and the second gear 60 can be engaged with the second precursor portion 201, the first convex portion 202, and the second concave portion 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 concave 102 and the second convex 103; the second gear 60 has different radii where it engages with the second precursor portion 201, the first 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.
The first gear 50 and the second gear 60 rotate synchronously, on one hand, the first gear 50 and the second gear 60 can be conveniently driven by one power source 40, on the other hand, the first gear 50 and the second gear 60 have the same angular velocity, and the first gear 50 and the second gear 60 are designed to have different radiuses, so that the differential motion of the first connecting rod 10 and the second connecting rod 20 can be realized, and the structure of a driving structure is simplified.

Analysis from the rotation angle of the first and second links: realizing the first open position and the second open position, as shown in fig. 11 and 12, the motor needs to be rotated by 3 angles: α1, α2, α3.
In the α1 range: the deflector moves from the closed position to the extended position, the first constant radius segment engages the first precursor portion, and the second constant radius segment engages the second precursor portion. Because the air deflector is an outward turning guide plate, if the air deflector rotates directly, the air deflector can interfere with the air duct frame, so that the air deflector needs to extend a certain distance to rotate again, or rotate while extending, and the air deflector extends and rotates simultaneously by adjusting the transmission ratio m and n without interfering with the air duct frame; in the case, the same initial radius of the first gear and the second gear is designed, and at the moment, the first connecting rod and the second connecting rod respectively rotate along respective circle centers and simultaneously extend out along the horizontal direction to be close to each other, and the air deflector extends out and overturns without interference of the air duct frame;
In the α2 range: the first radius changing section is engaged with the first concave section and the second radius changing section is engaged with the first convex section. After the air deflector extends and rotates for a certain distance, the first connecting rod and the second connecting rod can perform larger differential motion, and at the moment, the first connecting rod extends slowly, and the second connecting rod extends quickly, so that the air deflector extends and turns to a first open position within an angle alpha 2, namely, the air deflector moves from the extended position to the first open position;
in the α3 range: the third constant radius segment engages the second protrusion and the fourth constant radius segment engages the second recess. The air deflector moves from the first open position to the second open position, and the first connecting rod and the second connecting rod also need to perform larger differential motion, and at the moment, the first connecting rod stretches out faster, and the second connecting rod stretches out slower, so that the first connecting rod stretches out and turns to the second open position within an angle alpha 3.
L11<L21,L12>L22 and L11 are similar to L12, and the difference between L21 and L22 is larger. For example, l12=1.1χl11; l21=1.5×l11; l22=0.5×l11, and the diameters of the first gear and the second gear are controlled to beIn the range of from +.>First reduce to +.>Then increase to +.>The straight warp of the second gear is +.>First increase to +.>And then reduce to
The diameters of the first gear and the second gear are controlled to be The gear strength and stability are improved; controlled at->In the meantime, in order to reduce the space occupied by the driving mechanism, the larger the diameter is, the larger the transmission torque is required.
The motor drives the first gear and the second gear to rotate for 3 angles (alpha 1, alpha 2 and alpha 3), and corresponding transmission parameters are as follows:

The radius of the first gear is a variable value, the radius of the first connecting rod is changed along with the first gear, the radius of the first gear is firstly reduced from r11 to r12 in the angle alpha 1 to alpha 21, the transmission ratio of the first gear and the first connecting rod is a function m12, the radius of the first gear is increased from r12 to r13 in the angle alpha 21 to alpha 2, the transmission ratio of the first gear and the first connecting rod is a function m13, the radius of the second gear is a variable value, the radius of the second connecting rod is changed along with the second gear, the radius of the second gear is firstly increased from r21 to r22 in the angle alpha 1 to alpha 21, the transmission ratio of the second gear and the second connecting rod is a function n22, the transmission ratio of the second gear is reduced from r22 to r23 in the angle alpha 21 to alpha 2, and the transmission ratio of the second gear and the second connecting rod is a function n23. Since L11< L21, r12< r22; since L12> L22, r13> r23.α3 range: the radius R13 of the first gear is a fixed value, the radius R13 of the first connecting rod is a fixed value, the transmission ratio of the first gear to the first connecting rod is m14, the radius R23 of the second gear is a fixed value, the radius R23 of the second connecting rod is a fixed value, and the transmission ratio of the second gear to the second connecting rod is n24.
