In order to realize the movement process of the crank, the depth of the limiting rail 23 needs to be less than that of the through groove 21, so that the second transmission shaft 122 can smoothly move from the limiting rail 23 to the upper side of the through groove 21, and the first transmission shaft 121 can always move in the through groove 21.

The length of the first slide block 27 may be equal to the length of the second slide block 28, and the length of the position-limiting column 26 is smaller than the length of the first slide block 27, so that the position-limiting column 26 does not interfere with the motion track of the driving link 20 during the motion of the driving link 20. Moreover, the existence of the limiting column 26 can also prevent the air deflector 50 from shaking during the rotation of the air deflector 50.

Optionally, the rail portion comprises: a first track and a second track, wherein the first track is in a herringbone shape, and the first sliding block 27 moves in the first track; the second track is linear, and the second limiting part and the second sliding block 28 move in the second track.

Optionally, the first track includes a first linear track 41, a first branch track 42 and a second branch track 43, the first branch track 42 being in communication with the first linear track 41; the second branch rail 43 communicates with the first linear rail 41 and extends in a direction different from that of the first branch rail 42; when the first slider 27 of the driving connecting rod 20 moves in the first linear track 41, the second slider 28 and the second limiting portion move linearly in the second track to drive the air deflector 50 to extend to the first preset position; when the first sliding block 27 of the driving connecting rod 20 enters the first branch rail 42 or the second branch rail 43 from the first linear rail 41 to move, the second sliding block 28 and the second limiting portion continue to move linearly in the second rail, so as to drive the air deflector 50 to rotate.

Optionally, the second track comprises: a second linear track 44 and a third linear track 45. Optionally, the second limiting portion at least comprises 2 sliding blocks. Optionally, the second limiting portion includes a third slider 31, a fourth slider 32 and a fifth slider 33, which are arranged in a triangle, as shown in fig. 3, so that the limiting effect on the movement track of the driven link 30 is improved. Wherein the third slider 31 and the fourth slider 32 move in the second linear track 44, and the fifth slider 33 moves in the third linear track 45.

When the crank rotates in the first direction to make the second transmission shaft 122 move to the first limit end along the start end of the first limit section 231, the second transmission shaft 122 abuts against the first limit section 231 to provide the driving force for the driving connecting rod 20 to select the preset track, so as to drive the driving connecting rod 20 to enter the first branch track 42 to move, at this time, the driving connecting rod 20 changes direction in motion, the driven connecting rod 30 continues to move linearly along the second track, and the driving connecting rod 20 and the driven connecting rod 30 move relatively to drive the air deflector 50 to open upwards. Alternatively, the first direction may be a clockwise direction.

When the crank rotates in the second direction to make the second transmission shaft 122 move to the second limit end along the start end of the second limit section 232, the second transmission shaft 122 abuts against the second limit section 232 to provide the driving force for the driving connecting rod 20 to select the preset track, so as to drive the driving connecting rod 20 to enter the second branch track 43 for movement, at this time, the driving connecting rod 20 changes direction in movement, the driven connecting rod 30 continues to move linearly along the second track, and the driving connecting rod 20 and the driven connecting rod 30 move relatively to drive the air deflector 50 to open downwards. Alternatively, the second direction may be a counterclockwise direction.

Optionally, the time node when the second transmission shaft 122 of the crank moves to the position close to the first limit end or the position close to the second limit end is earlier than or equal to the time node when the first connecting rod 20 selects the first branch track 42 or the second branch track 43, so that the first connecting rod 20 moves along the direction of the preset track under the abutting force of the second transmission shaft 122 to change the direction. The direction of the preset track is the extending direction of the first branch track 42 or the extending direction of the second branch track 43.

The motion assembly provided by the embodiment of the present disclosure includes a driving link 20, a driven link 30, a track plate 40 and a driving element 10, and the motion manner of the motion assembly driving the air deflector 50 according to the embodiment of the present disclosure is as follows:

the air deflector 50 is in the closed state and the initial state of the moving assembly is shown in fig. 8. When the driving element 10 rotates from the initial position in the first direction, the first transmission shaft 121 slides in the through groove 21 of the driving link 20 to provide a driving force for the driving link 20 to move, so that the driving link 20 linearly moves along the track portion under the limitation of the first slider 27 and the second slider 28, the second transmission shaft 122 moves in the first limiting section 231 of the limiting track 23, and meanwhile, the driven link 30 linearly moves under the limitation of the second track, and further, the driving link 20 and the driven link 30 drive the air deflector 50 to linearly extend out of the air conditioner to the first preset position, as shown in fig. 9. It can be understood that, when the driving element 10 rotates in the second direction from the initial position, the driving link 20 and the driven link 30 can also drive the air deflector 50 to linearly extend to the first preset position. It will be appreciated that in the first preset position, the first slider 27 of the driving link 20 moves to the end of the first linear track 41, i.e. is about to enter the first branch track 42 or the second branch track 43.

When the driving element 10 rotates in the first direction, after the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 is about to move to the first limit end of the limit track 23, a contact force exists between the second transmission shaft 122 and the first limit section 231, the contact force is a driving force of the driving link 20 selecting the preset track, so that the first slider 27 of the driving link 20 moves along the first branch track 42, the second slider 28 of the driving link 20 continues to move in the second linear track 44, the driving link 20 changes direction under the limitation of the first slider 27 and the second slider 28, and meanwhile, the driven link 30 continues to move linearly in the second track, so that the air deflector 50 is opened upwards under the driving of the driving link 20 and the driven link 30, as shown in fig. 10.

When the driving element 10 rotates in the second direction, after the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 is about to move to the second limit end of the limit track 23, a contact force exists between the second transmission shaft 122 and the second limit section 232, the contact force is a driving force of the driving link 20 selecting the preset track, so that the first slider 27 of the driving link 20 moves along the second branch track 43, the second slider 28 of the driving link 20 continues to move in the second linear track 44, the driving link 20 changes direction under the limitation of the first slider 27 and the second slider 28, and meanwhile, the driven link 30 continues to move linearly in the second track, so that the air deflector 50 is opened downward under the driving of the driving link 20 and the driven link 30, as shown in fig. 11.
