The invention discloses a low-wind-resistance side skirt baffle, and belongs to the technical field of resistance reduction of rear wheel spoilers, the low-wind-resistance side skirt baffle comprises a wheel cover, a wheel brow and a rear wheel spoiler, the wheel brow is arranged at the edge of the wheel cover, the rear wheel spoiler is arranged below the wheel cover, the low-wind-resistance side skirt baffle further comprises a side skirt baffle body, the side skirt baffle body is connected with the rear wheel spoiler, and the side skirt baffle body is installed on the wheel cover. The side skirt baffle and the rear wheel spoiler are located in the same plane, the side skirt baffle is perpendicular to the ground, and the side skirt baffle and the rear wheel spoiler are integrally formed. The resistance reduction amount of the side skirt baffle is 0.002-0.006 Cd, the endurance of a corresponding pure electric automobile can be prolonged by 4 kilometers to the maximum extent, and the aim of balancing the aesthetic requirement of the modeling can be achieved without changing the originality of the modeling at the position; seen from the front, the outermost side of the side skirt baffle shields the edge of a tire, so that incoming flow along a vehicle body forcibly turns at the position and does not directly impact the tire, and the effect of turbulent flow is achieved. Therefore, the air flow is prevented from directly impacting the tire to reduce the positive pressure area of the tire, and the wind resistance coefficient is reduced.

    本发明公开了一种低风阻侧裙挡板,属于后轮扰流板降阻技术领域,包括轮罩、轮眉、后轮扰流板,轮罩边缘设有轮眉,轮罩下方设有后轮扰流板,还包括侧裙挡板,侧裙挡板与后轮扰流板连接,侧裙挡板安装在轮罩上,侧裙挡板与后轮扰流板在同一平面内,侧裙挡板与地面垂直,侧裙挡板与后轮扰流板一体成型;本发明侧裙挡板降阻量为0.002Cd‑0.006Cd,对应纯电汽车续航最大可提升4公里,本发明可以不改变造型在此处的创意,达到平衡造型的美学需求的目的;本发明侧裙挡板从前方看,最外侧遮挡住轮胎的边缘,使沿车身的来流在此处强制转弯,不直接冲击轮胎,起到扰流的作用。因而避免了气流直接冲击轮胎,而导致轮胎的正压面积减小,实现降低风阻系数。
