The invention relates to a flow guide device, a bottom guard plate assembly and a vehicle, the flow guide device comprises a flow guide body, the flow guide body comprises a windward flow guide face and a leeside located on the back side of the windward flow guide face, the flow guide body is arranged on a vehicle bottom guard plate, and the leeside is located in front of vehicle tires. The windward flow guide surface at least comprises a first curved surface and a second curved surface connected with the edge of the first curved surface, at least part of the first curved surface is bent in the direction deviating from the vehicle tire, and the second curved surface is bent in the direction deviating from the vehicle bottom guard plate, so that airflow generated when a vehicle runs cannot directly impact on the vehicle tire; the air flow impacts on the windward flow guide face of the flow guide device instead of impacting on the windward flow guide face of the flow guide device, so that the air flow can be guided through the windward flow guide face and then flows to the outer side of a vehicle tire without impacting on the vehicle tire to form a high-pressure area, wind resistance is effectively reduced, and 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,通过将该导流装置设置为包括导流主体,导流主体包括迎风导流面和位于迎风导流面背侧的背风面,导流主体设置在车辆底护板上且背风面位于车辆轮胎的前方。迎风导流面至少包括第一曲面和与第一曲面的边缘相接的第二曲面,第一曲面的至少部分沿背离车辆轮胎的方向弯曲设置,第二曲面沿背离车辆底护板的方向弯曲设置,从而使得车辆行驶时产生的气流不会直接冲击在车辆轮胎上,而是冲击在导流装置的迎风导流面上,从而使气流可以经迎风导流面进行导流后流至车辆轮胎的外侧,而不会冲击在车辆轮胎上形成高压区,从而有效降低了风阻,提升了车辆的经济性。
