However, the number of the air dam devices 3 is not limited, and may be designed as needed, for example, one, two, four or more, as long as the spoiler 5 of the plurality of air dam devices 3 is free from a gap in the fully deployed state. For example, when the number of the air dam devices 3 is two, the two air dam devices 3 are symmetrically disposed at the left and right sides of the bottom of the vehicle without a gap between the spoilers 5 of the two air dam devices 3. Also, the size of each air dam apparatus 3 may be designed as desired, and not every air dam apparatus 3 needs to be uniformly sized.

An example in which an air dam apparatus 3 includes a spoiler 5 will be described below.
The drive mechanism 4 has a drive shaft 412. The spoiler 5 is connected with the driving mechanism 4, and is provided to be foldable, and has a fully unfolded state and a fully folded state, each of the spoiler 5 having a windward side.

The spoiler 5 is further configured to deform and switch to a fully deployed state under the driving of the driving mechanism 4, and when the spoiler 5 is in the fully deployed state, the windward side of the spoiler 5 faces the front end of the vehicle. Here, the "fully expanded state" and the "fully folded state" are relative concepts, and cannot be narrowly understood as: in the fully unfolded state, no more can be unfolded at all, and in the fully folded state, no more can be folded at all. It can be understood that: in the fully unfolded state the windward side of the spoiler 5 is substantially smooth without folds or without two substantially parallel faces, whereas in the fully folded state the windward side of the spoiler 5 is more folds or with two substantially parallel faces.

In this embodiment, the number of the transmission assemblies 43 is four, but the number of the transmission assemblies 43 is not limited to four, and may be one, two, three, five or more, and may be set according to actual needs. One end of the spoiler 5 is connected with the support member 42. The support member 42 has a hinged end 421, the hinged end 421 being hinged to the bottom of the vehicle. Each transmission assembly 43 includes a cam structure 431 and a link assembly 432, the cam structure 431 is connected to the driving shaft 412 of the driving motor 41, and the link assembly 432 is connected to the cam structure 431 and is used for directly driving the support member 42 or directly driving the spoiler 5 to move so as to drive the spoiler 5 to deform.
