The invention discloses a structural design for solving whistling of a tip opening of an automobile engine hood, and belongs to the technical field of automobiles. The structural design comprises an automobile front bumper body which is a main body of the structural design; the engine cover is hinged to the automobile body and located on the top of the automobile front bumper body; the front bumper grille outer decoration strip is arranged on the outer side of the automobile front bumper body; the turbulent flow cylinder is arranged on the outer surface of the front bumper grille outer decoration strip. By arranging the turbulent flow cylinder and designing the characteristics of the turbulent flow cylinder on the front bumper grille outer decoration strip, an original airflow flowing path is disturbed, and the characteristics of the turbulent flow cylinder can enable airflow to bypass the tip end of an engine cover or reduce the direct impact degree of the airflow, so that airflow separation and vortex formation are reduced, and the airflow separation efficiency is improved. In addition, the turbulent flow cylinder can be formed by conducting die repairing on the outer surface of the front bumper grille outer decoration strip, only a small amount of die repairing cost is brought, the cost is negligible, and implementation is easy.

    本发明公开了一种解决汽车引擎盖尖端口哨声的结构设计,属于汽车技术领域,包括汽车前保险杠本体,其为本结构设计的主体;引擎盖,其铰接于车体并位于汽车前保险杠本体的顶部;前保险杠格栅外饰条,其安装设置于汽车前保险杠本体的外侧;扰流圆柱体,其设置于前保险杠格栅外饰条的外表面。本发明通过设置扰流圆柱体,通过在前保险杠格栅外饰条上设计扰流圆柱体的特征,扰动了原本的气流流动路径,扰流圆柱体的特征可以使气流绕过引擎盖的尖端或降低其直接冲击的程度,从而减少气流分离和涡流的形成,从而降低口哨声的发生概率,且扰流圆柱体可通过在前保险杠格栅外饰条的外表面修模成型,仅带来少量的修模费用,成本忽略不计,易于实施。
