The disclosed embodiment also provides a motion assembly including the link assembly for the air deflection plate 50 described above, as shown in fig. 8-12.

In the embodiment of the present disclosure, the moving assembly includes a driving link 20, a driven link 30, a driving element 10 and a track plate 40, the driving element 10 provides a driving force for the movement of the driving link 20 and the driven link 30, and a track portion of the track plate 40 defines a movement track of the driving link 20 and the driven link 30, so that the air deflector 50 extends and rotates.

The moving assembly provided by the embodiment of the present disclosure drives the air deflector 50 to move as follows:

the initial state of the moving assembly with the air deflector 50 in the closed state is shown in figure 9. When the driving element 10 rotates in the third direction or the fourth direction from the initial position shown in fig. 9, the first transmission shaft 121 slides in the driving link 20 to drive the driving link 20 and the driven link 30 to move, wherein the driving link 20 moves linearly along the first linear track 41, and the driven link 30 moves linearly along the second track, so as to drive the air deflector 50 to move linearly to the first preset position. The first predetermined position can be understood as the position of the wind deflector 50 corresponding to the first sliding column 25 of the driving link 20 when the first branch rail 42 or the second branch rail 43 is to be selected.

When the driving element 10 rotates in the third direction, when the air deflector 50 moves to the first preset position, the second transmission shaft 122 of the driving element 10 moves to the first limit point a, and due to the existence of the abutting force between the second transmission shaft 122 and the first limit point a, the driving force for selecting the track is provided for the first sliding column 25 of the driving connecting rod 20, so that the first sliding column 25 of the driving connecting rod 20 enters the first branch track 42 after moving along the right side edge of the first linear track 41, the second sliding column 26 of the driving connecting rod 20 passes through the through slideway 35 of the driven connecting rod 30 to continue moving in the second linear track 44, and the movement of the driving connecting rod 20 is redirected. Meanwhile, the driven link 30 continues to move linearly along the second track, so that the air deflector 50 is opened upward by the driving link 20 and the driven link 30 together, as shown in fig. 11.

When the driving element 10 rotates in the fourth direction, when the air deflector 50 moves to the first preset position, the second transmission shaft 122 of the driving element 10 moves to the second limit point B, and due to the existence of the abutting force between the second transmission shaft 122 and the second limit point B, the driving force for selecting the track is provided for the first sliding column 25 of the driving connecting rod 20, so that the first sliding column 25 of the driving connecting rod 20 moves along the left side edge of the first linear track 41 and then enters the second branch track 43, the second sliding column 26 of the driving connecting rod 20 passes through the through slideway 35 of the driven connecting rod 30 to continue moving in the second linear track 44, and the movement direction of the driving connecting rod 20 is changed. Meanwhile, the driven link 30 continues to move linearly along the second track, so that the air deflector 50 is opened downward by the driving link 20 and the driven link 30 together, as shown in fig. 12.
