The invention relates to the technical field of vehicles, and particularly relates to a vehicle doorsill structure and a vehicle. The vehicle doorsill structure comprises a doorsill outer shell and aninner filling reinforcing structure, wherein the inner filling reinforcing structure is arranged in the doorsill outer shell and comprises foamed aluminum and an aluminum pipe which are matched witheach other, the aluminum pipe extends in the length direction of the threshold outer shell, and the foamed aluminum is arranged between the aluminum pipe and the threshold outer shell. According to the vehicle doorsill provided by the embodiment of the invention, the inner filling reinforcing structure is arranged in the vehicle doorsill, the structural high strength of the vehicle doorsill is greatly improved, and meanwhile, the structural weight of the vehicle doorsill is remarkably reduced through the design that the foamed aluminum is matched with the aluminum pipe. In addition, the foamedaluminum in the inner filling reinforcing structure can absorb impact force borne by the doorsill of the vehicle in the collision process of the vehicle, and damage to passengers can be prevented orreduced.
本申请涉及车辆技术领域,具体涉及一种车辆门槛结构及车辆。该车辆门槛结构包括:门槛外壳和内填充加强结构;其中,内填充加强结构设置于门槛外壳内,包括相配合的泡沫铝和铝管,铝管沿门槛外壳的长度方向延伸,泡沫铝设置于铝管和门槛外壳之间。本申请实施例提供的车辆门槛,内部内置了内填充加强结构,大大提升了自身结构高强度,同时泡沫铝与铝管相配合的设计显著降低了车辆门槛的结构重量。此外,内填充加强结构中的泡沫铝可以吸收车辆碰撞中车辆门槛受到的冲击力,有助于防止或减少乘员的损伤。
