Multiple fins 81 on the windward side of spoiler 5, fin 81 can individually be fixed on the laminated structure on spoiler 5, can also
The laminated structure being directly bent to form on spoiler 5, airflow function form thrust on fin 81, to fin 81.
Further, in the present embodiment, fin 81 is evenly arranged in matrix on the windward side of spoiler 5.Fin 81
Multirow is set, and often row is provided with multiple fins 81.The arrangement form of two rows of fins 81, certainly, the number of fin 81 are given in Fig. 2
Amount and arrangement form can also be other forms, specifically be set according to actual conditions, it is not limited to which the present embodiment is described
Structure type.
As shown in figure 4, present embodiments providing another specific wind selection structure 8, which is to be arranged at flow-disturbing
Multiple grooves 82 on the windward side of plate 5.Groove 82 is recessed inwardly to be formed by the windward side of spoiler 5, due to groove 82
It can be acted on groove 82 in the presence of angle, air-flow windward between concave surface and airflow direction, thrust be generated to groove 82, so as to promote
Spoiler 5 moves.
Further, in the present embodiment, groove 82 is evenly arranged in matrix on the windward side of spoiler 5.Groove 82
Multirow is set, and often row is provided with multiple grooves 82.The arrangement form of two rows of grooves 82, certainly, the number of groove 82 are given in Fig. 4
Amount and arrangement form can also be other forms, specifically be set according to actual conditions, it is not limited to which the present embodiment is described
Structure type.
As shown in figure 3, in the present embodiment, the position that support plate 7 is rotatablely connected with mounting bracket 1 is additionally provided with damped part
10.Damped part 10 is set i.e. in the second shaft 9, damped part 10 can prevent support plate 7 and spoiler 5 from shaking back and forth,
Noise is avoided to generate.
