The crank element 1 rotates along a first direction, the first transmission shaft 11 of the crank element 1 slides in the first slide 201 of the driving connecting rod piece 2, the driving connecting rod piece 2 moves linearly under the limitation of the first end slide block 211 and the first cooperation slide block 212, meanwhile, the driven connecting rod piece 3 moves linearly under the limitation of the second track 44, and then the driving connecting rod piece 2 and the driven connecting rod piece 3 drive the air deflector 6 to extend linearly to a first preset position, and the first preset position is shown in fig. 9 when the crank element 1 rotates along the first direction.

After the crank element 1 reaches the first preset position, the second transmission shaft 12 of the crank element 1 enters the first branch slideway 202, the second transmission shaft 12 and the first branch slideway 202 generate a butting force, so as to control the first end slider 211 of the driving connecting rod element 2 to move towards the first branch slideway 42, and at the moment, the first cooperation slider 212 of the driving connecting rod element 2 continues to move linearly, the driving connecting rod element 2 changes direction of movement under the limitation of the first end slider 211 and the first cooperation slider 212, and the driven connecting rod element 3 continues to move linearly, so that the air deflector 6 is driven by the driving connecting rod element 2 and the driven connecting rod element 3 to open upwards.

After the crank element 1 reaches the first preset position, the second transmission shaft 12 of the crank element 1 enters the second branch slideway 203, the second transmission shaft 12 and the second branch slideway 203 generate a butting force, so as to control the first end slider 211 of the driving connecting rod element 2 to move towards the second branch slideway 43, and at the moment, the first cooperation slider 212 of the driving connecting rod element 2 continues to move linearly, the driving connecting rod element 2 changes direction under the limitation of the first end slider 211 and the first cooperation slider 212, and the driven connecting rod element 3 continues to move linearly, so that the air deflector 6 is driven by the driving connecting rod element 2 and the driven connecting rod element 3 to open downwards.

Optionally, the number of the moving assemblies is two, and the two moving assemblies are respectively connected with two ends of the air deflector 6. In this way, the stability of the air deflector 6 in extension and rotation can be improved.
