The invention relates to a wind resistance kit, a vehicle and a vehicle wind resistance control method. The two ends of a rotating shaft are used for being rotationally connected to two mounting parts, in the width direction of the vehicle, of the inner side of a front face shield; a flexible stop block is mounted on the rotating shaft; the driving assembly is installed on the front face shield and is in transmission connection with the rotating shaft so as to drive the flexible check block to rotate with the rotating shaft as the center to block the gap between the front face shield and the bumper, and therefore when the vehicle speed is high, the flexible check block blocks the gap, and the wind resistance of the whole vehicle is reduced. A large amount of external airflow is effectively prevented from flowing into an engine port, the internal pressure of an engine cabin is effectively reduced, positive pressure borne by parts in the cabin is reduced, and the internal and external pressure difference is reduced, so that wind resistance is reduced, and the fuel economy of the whole vehicle is improved; in addition, during cold start of the vehicle, the gap can be blocked to isolate external cold air, so that the engine quickly enters the optimal working temperature, and the preheating time is shortened.
本申请涉及一种风阻套件、车辆、车辆风阻控制方法,由于转轴的两端用于转动连接在前面罩内侧在车辆宽度方向上的两个安装部上;转轴上安装柔性挡块;驱动组件安装在前面罩上,与转轴传动连接,以带动柔性挡块以转轴为中心转动,以将前面罩和保险杠之间的间隙封堵,从而当车速较高时,使柔性挡块封堵间隙,降低整车风阻;有效遮挡外部气流大量流向发动机机场内,有效降低发动机机舱内部压力,机舱内部零部件所受正压减少,降低内外压差,从而降低风阻,提升整车燃油经济性;另外在车辆冷启动时,可以封堵间隙隔绝外部冷空气,使发动机快速进入最佳工作温度,减少预热时间。
