Optionally, the rail portion comprises a first rail and a second rail, the first rail being in a chevron shape; the second track is linear; under the limitation of the first track and the second track, the driving connecting rod 20 firstly moves linearly in synchronization with the driven connecting rod 30 to drive the air deflector 50 to extend to the first preset position, and then moves relative to the driven connecting rod 30 to drive the air deflector 50 to rotate.

Alternatively, the second rail includes three linear rails, i.e., a second linear rail 44, a third linear rail 45, and a fourth linear rail 46, and the follower link 30 moves linearly along the three linear rails of the second rail at all times during the extension and rotation of the air guide plate 50.

Optionally, the first track comprises a first straight track 41, a first branch track 42 and a second branch track 43; the first branch rail 42 communicates with the first linear rail 41; the second branch rail 43 communicates with the first linear rail 41; when the second transmission shaft 122 of the driving element 10 moves to the first limit point a, the driving element 10 drives the first sliding column 25 of the driving connecting rod 20 to move along the right side edge of the first linear track 41, so that the first sliding column 25 enters the first branch track 42, and then the driving connecting rod 20 and the driven connecting rod 30 move relatively to drive the air deflector 50 to open upwards; when the second transmission shaft 122 of the driving element 10 moves to the second limit point B, the driving element 10 drives the first sliding column 25 of the driving connecting rod 20 to move along the left side edge of the first linear track 41, so that the first sliding column 25 enters the second branch track 43, and the driving connecting rod 20 and the driven connecting rod 30 move relatively to drive the air deflector 50 to open downwards. Wherein the first sliding column 25 moves in the first linear track 41, the first branch track 42 and the second branch track 43, the second sliding column 26 moves in the second linear track 44, and the first sliding column 25 and the second sliding column 26 jointly define the motion track of the driving link 20. The third sliding column 31 moves in the second linear track 44, the fourth sliding column 32 moves in the third linear track 45, and the fifth sliding column 33 moves in the fourth linear track 46.

The principle that the driving box provided by the embodiment of the present disclosure drives the air deflector 50 to move is as follows:

when the driving element 10 rotates along the first direction, the second transmission shaft 122 moves to the first limit point a along the U-shaped section 233, the second transmission shaft 122 abuts against the first limit point a, and gives a driving force to the first sliding column 25 of the driving connecting rod 20 to select a preset track, so that the first sliding column 25 moves along the right side edge of the first linear track 41 and then enters the first branch track 42, the driving connecting rod 20 changes the direction of the 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 upwards. Optionally, the first direction is clockwise. As shown in fig. 9.

When the driving element 10 rotates along the second direction, the second transmission shaft 122 moves to the second limit point B along the U-shaped section 233, the second transmission shaft 122 abuts against the second limit point B, and gives a driving force to the first sliding column 25 of the driving connecting rod 20 to select a preset track, so that the first sliding column 25 moves along the left side of the first linear track 41 and then enters the second branch track 43, the driving connecting rod 20 changes the direction of the 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. Optionally, the second direction is a counter-clockwise direction. As shown in fig. 10.
