The invention relates to the technical field of vehicles, in particular to a bottom protection plate, a vehicle chassis and a vehicle. The bottom protection plate comprises an oil tank protection plate which is installed on a vehicle chassis and located at the bottom of an oil tank; the fuel tank protection plate comprises a front end close to the head of a vehicle and a tail end close to the tail of the vehicle. The oil tank protection plate obliquely extends in the direction away from the oil tank in the direction from the front end to the tail end. When airflow approaches the oil tank protection plate, at least part of the inclined oil tank protection plate can slowly guide the airflow to flow, the airflow is prevented from vertically impacting the oil tank protection plate to form a high-pressure area, the size of a positive-pressure area of the oil tank protection plate is reduced, and the wind resistance coefficient can be effectively reduced.

    本公开涉及车辆技术领域,尤其涉及一种底护板、车辆底盘及车辆。本公开提供的底护板包括油箱护板,安装于车辆底盘,并位于油箱底部;所述油箱护板包括靠近车辆头部的前端和靠近所述车辆尾部的尾端;沿从所述前端到所述尾端的方向上,所述油箱护板向远离所述油箱的方向倾斜延伸。在气流接近油箱护板时,至少部分倾斜的油箱护板可以缓慢引导气流流动,避免气流垂直撞击油箱护板形成高压区,减小了油箱护板的正压区域大小,能有效降低风阻系数。
