The invention relates to a bumper flow guide structure, a frame and a vehicle, and the structure comprises a bumper system which is provided with a fixed part and a front end face located in front of the fixed part; the flow guide structure is installed on the fixing part and provided with a first flow guide face, and the first flow guide face extends downwards from the bottom face of the bumper system and obliquely in the direction close to the front end face, so that a cavity with a forward opening is formed between the first flow guide face and the bottom face of the bumper system. When airflow in the front direction flows to the front bumper system, the airflow can enter the cavity through the opening, the flowing direction of the airflow is changed in the cavity, and the airflow can reversely flow forwards along the first flow guide face extending obliquely, bypass the flow guide structure and then flow backwards; positive pressure of airflow on chassis components of the commercial vehicle can be effectively reduced, so that wind resistance of the whole vehicle can be reduced, economical efficiency of the whole vehicle is improved, and contribution value of the bumper system to reduction of the wind resistance of the whole vehicle is improved.
本发明涉及一种保险杠导流结构、车架及车辆,其包括:保险杠系统,保险杠系统具有固定部,以及位于固定部前方的前端面;导流结构,导流结构安装于固定部,且导流结构具有第一导流面,第一导流面自保险杠系统的底面向下且向靠近前端面的方向倾斜延伸,使第一导流面与保险杠系统的底面之间形成开口朝向前方的腔体。当前方的气流流向前保险杠系统时,气流可以通过开口进入腔体,并在腔体内改变气流流动的方向,气流可以沿着倾斜延伸的第一导流面反向向前流动并绕过导流结构再向后流动,在第一导流面的阻挡下,能够有效减少气流对商用车底盘部件的正压力,从而可以降低整车风阻,提升整车的经济性,因此,提升了保险杠系统对降低整车风阻的贡献值。
