The invention relates to a flow guiding device, a bottom protection plate assembly and a vehicle, the flow guiding device comprises a bottom protection plate and at least one flow guiding main body, the flow guiding main body is arranged on the bottom protection plate, and the flow guiding main body is located on the side, close to a vehicle head, of an auxiliary frame suspension structure of the vehicle in the direction from the vehicle head to the vehicle tail of the vehicle; the windward side is formed by the face, deviating from the auxiliary frame suspension structure, of the flow guide body and is a smooth surface, so that airflow does not directly impact on the auxiliary frame suspension structure but impacts on the windward side of the flow guide body, and the airflow impacting on the windward side is finally discharged through the outer side of the auxiliary frame suspension structure. Due to the fact that the windward side is the smooth surface, airflow impacting on the windward side can form a stable flow field, the turbulent flow phenomenon is avoided, the phenomenon that airflow impacts on the auxiliary frame suspension structure, turbulent flow occurs, and wind resistance is increased is effectively avoided, the wind resistance is effectively reduced, and the economical efficiency of a vehicle is improved.
本公开涉及一种导流装置、底护板总成以及车辆,通过设置导流装置包括底护板以及至少一个导流主体,将导流主体设置在底护板上,且在沿车辆的车头至车尾的方向上,导流主体位于车辆的副车架悬挂结构的靠近车头的一侧,使导流主体的背离副车架悬挂结构的一面形成迎风面,迎风面为平滑表面,从而使得气流不会直接冲击在副车架悬挂结构上,而是冲击在导流主体的迎风面上,冲击在迎风面上的气流最终经副车架悬挂结构的外侧排出,由于迎风面为平滑表面,从而使得冲击在迎风面上的气流可以形成稳定的流场而不会发生紊流现象,从而有效避免了气流冲击在副车架悬挂结构上并发生紊流导致风阻增大的现象出现,从而有效降低了风阻,提升了车辆的经济性。
