The invention relates to the technical field of vehicle parts, and provides a doorsill beam and a vehicle, the doorsill beam comprises a beam body and a first reinforcing structure, the first reinforcing structure is made of a continuous fiber reinforced composite material, the beam body is provided with a first through cavity in the length direction of the beam body, and a rib structure is arranged in the first through cavity; the rib structures extend in the length direction of the beam body and divide the first through cavity into a plurality of cavity bodies, and the first reinforcing structures are arranged in at least one cavity body. Therefore, the weight and the cost of the doorsill beam can be reduced while the small offset collision performance of the doorsill beam is improved by 25%, the weight and the production cost of the whole vehicle are further reduced, and lightweight design is facilitated.
本发明涉及车辆零部件技术领域,并提供了一种门槛梁及车辆,所述门槛梁包括梁本体和第一加强结构,所述第一加强结构采用连续纤维增强复合材料制作,所述梁本体沿其长度方向设有第一贯通腔,所述第一贯通腔内设有筋条结构,所述筋条结构沿所述梁本体的长度方向延伸并将所述第一贯通腔分隔为多个腔体,至少一个所述腔体内设有所述第一加强结构。这样,能够在提升门槛梁的25%小偏置碰撞性能的同时减少门槛梁的重量和成本,进而降低整车的重量和生产成本,便于轻量化设计。
