The driving mechanism is in driving connection with the air deflector 40, and is used for driving the air deflector 40 to move relative to the air outlet 1001, so as to open or close the air outlet 1001.

The drive mechanism includes a power source, a second link 10 and a first link 30. The driving mechanism is used for driving the driven member to move, and the driven member is specifically taken as an air deflector for example.

As shown in fig. 4, the third radius 605 engages the gear teeth 108 on the precursor portion 103, corresponding to movement of the deflector 40 from the closed position to the extended position; as shown in fig. 11, the second radius 604 engages the gear teeth 108 on the boss 102 and the corresponding deflector 40 moves from the extended position to the first open position; as shown in fig. 14, the first radius 603 engages the gear teeth 108 on the recess 101 and the corresponding deflector 40 moves from the first open position to the second open position.

The radius of the third radius 605 is greater than, less than, or equal to the radius of the second radius 604, and the radius of the second radius 604 is less than the radius of the first radius 603, such that the air deflection 40 is movable from the closed position through the extended position to the first open position or the second open position.

Optionally, the radius of the third radius 605 is smaller than the radius of the first radius 603 and smaller than the radius of the second radius 604.

Optionally, during movement of the deflector 40 from the closed position to the second open position, the radius of the non-circular gear 60 at which it engages the gear teeth 108 increases, i.e., the radius of the third radius 605 is less than the radius of the second radius 604, and the radius of the second radius 604 is less than the radius of the first radius 603.

Specifically, since the air deflector 40 is an eversion type guide plate, if the air deflector 40 is directly rotated during the movement from the closed position to the first open position, it interferes with the duct frame, and thus it is necessary to extend the air deflector 40 a distance and then rotate it, or to extend it while rotating it, and then move it to the extended position, in which the air deflector 40 is directed toward the air outlet 1001, and then turn it from the extended position to the first open position. By designing the radius of the non-circular gear 60 such that the second link 10 and the first link 30 move in the same direction from the closed position to the extended position, they extend outward by similar distances, the air deflector 40 extends to the extended position or is flipped over to the extended position while extending. As shown in fig. 1, 3 and 4, at this point, third radius 605 engages gear teeth 108 on precursor 103 and first groove segment 202 mates with boss 303.

As shown in fig. 9 to 11, after the air deflector 40 extends a distance to reach the extended position, the movement directions of the second link 10 and the first link 30 are still the same, and the second link 10 and the first link 30 can perform a larger differential movement, for example, the second link 10 extends faster and the first link 30 extends slower, so that the air deflector 40 turns to the first open position. At this point, second radius 604 engages gear teeth 108 on boss 102 and first groove segment 202 mates with boss 303.

As shown in fig. 12 to 14, when the air deflector 40 moves from the first open position to the second open position, the movement direction of the first link 30 is a first movement direction, the movement direction of the second link 10 is a second movement direction, and the first movement direction is opposite to the second movement direction. For example, the first link 30 is retracted into the duct and the second link 10 continues to extend along the length of the duct to flip the deflector 40 to the second open position. At this time, the first radius 603 engages with the gear teeth 108 on the recess 101, and the second groove segment 203 mates with the boss 303.

Alternatively, the second link 10 is rotatably or slidably coupled to the deflector 40.

Alternatively, as shown in fig. 15 to 20, in the case where the second link 10 is rotatably connected to the wind deflector 40, the second link 10 includes a first sub-link 104 and a second sub-link 105.

The second link 10 includes a first sub-link 104 and a second sub-link 105 rotatably coupled to increase the freedom of movement of the second link 10 to effect movement of the damper 40 between the closed position, the first open position, and the second open position.

When the second link 10 is slidably connected to the wind deflector 40, the second link 10 is of an integral structure. At this time, one of the second link 10 and the wind deflector 40 is provided with a slide groove 403, and the other is provided with a slide shaft 109, and the slide shaft 109 is slidably provided in the slide groove 403.

The air guide surface 404 is provided with a first protrusion 401, and the chute 403 or the slide shaft 109 is provided on the first protrusion 401. As shown in fig. 4, the chute 403 is provided on the first convex portion 401.

When the second link 10 is rotatably connected to the air deflector 40, the second link 10 is rotatably connected to the first protrusion 401 to realize the rotational connection of the second link 10 to the air deflector 40.

As shown in fig. 3, the air guiding surface 404 is provided with a second protrusion 402, and the first link 30 is rotatably connected with the second protrusion 402, so as to realize the rotational connection of the first link 30 and the air guiding plate 40.

The rotational connection between the second link 10 and the air deflector 40 and the rotational connection between the first link 30 and the air deflector 40 are staggered, and are sequentially arranged in the width direction of the air deflector 40 as shown in fig. 3.

When the transmission member is the non-circular gear 60, the transmission shaft 601 coincides with the axis of the non-circular gear 60, so as to realize that the motor drives the non-circular gear 60 to rotate.

As shown in fig. 6, a transmission shaft 601 is disposed on the non-circular gear 60, a shaft hole is disposed on the transmission shaft 601, the driving member 50 is a motor, and a motor shaft penetrates into the shaft hole to realize connection between the motor shaft and the non-circular gear 60. Dodge hole 301 extends along the direction of movement of first link 30, and transmission shaft 601 and dodge hole 301 looks adaptation, and the opposite both sides wall butt of transmission shaft 601 respectively with dodge hole 301 opposite both sides wall for in-process is linear motion to first link 30, dodge hole 301 can move for transmission shaft 601, and transmission shaft 601 has the guide effect to the motion of first link 30, and guide first link 30 is linear reciprocating motion.
