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 give the first connecting rod 20 a driving force for selecting a preset track, so as to drive the first connecting rod 20 to enter the first branch track 42 to move, at this time, the first connecting rod 20 changes the direction of the movement, the second connecting rod 30 continues to move linearly along the second track, and the first connecting rod 20 and the second 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, the first connecting rod 20 is driven by the driving force of the preset track selected by the second transmission shaft to enter the second branch track 43 for movement, at the moment, the first connecting rod 20 changes direction in movement, the second connecting rod 30 continues to move linearly along the second track, and the first connecting rod 20 and the second connecting rod 30 move relatively to drive the air deflector 50 to open downwards. Alternatively, the second direction may be a counterclockwise direction.

The disclosed embodiment also provides a motion assembly including the link assembly for the air deflection plate 50 described above, as shown in fig. 6-12.

The moving assembly provided by the embodiment of the present disclosure includes a driving element 10, a first link 20, a second link 30, and a track plate 40, wherein the driving element 10 provides a driving force for the movement of the first link 20 and the second link 30, and a track portion of the track plate 40 defines a movement track of the first link 20 and the second link 30, so that the air guiding plate 50 extends and rotates.

The moving component provided by the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

the air deflector 50 is in the closed state and the initial state of the moving assembly is shown in fig. 9. 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 first link 20 to provide a driving force for the first link 20 to move, so that the first link 20 moves linearly 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 second link 30 also moves linearly under the limitation of the second track, and further, the first link 20 and the second link 30 drive the air deflector 50 to linearly extend out of the air conditioner to the first preset position, as shown in fig. 10. It can be understood that, when the driving element 10 rotates in the second direction from the initial position, the first connecting rod 20 and the second connecting rod 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 first 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, and a contact force exists between the second transmission shaft 122 and the first limit section 231, the contact force selects a driving force of the preset track for the first link 20, so that the first slider 27 of the first link 20 moves along the first branch track 42, the second slider 28 of the first link 20 continues to move in the second linear track 44, the first link 20 changes direction of movement under the limitation of the first slider 27 and the second slider 28, and meanwhile, the second link 30 continues to move linearly in the second track, so that the air deflector 50 is opened upward under the driving of the first link 20 and the second link 30, as shown in fig. 11.

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, and a contact force exists between the second transmission shaft 122 and the second limit section 232, the contact force selects a driving force of the preset track for the first connecting rod 20, so that the first slider 27 of the first connecting rod 20 moves along the second branch track 43, and the second slider 28 of the first connecting rod 20 continues to move in the second linear track 44, the first connecting rod 20 changes direction in movement under the limitation of the first slider 27 and the second slider 28, and meanwhile, the second connecting rod 30 continues to move linearly in the second track, so that the air deflector 50 is driven by the first connecting rod 20 and the second connecting rod 30 to open downward, as shown in fig. 12.
