Abstract

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.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a vehicle threshold structure and a vehicle. Background technique [0002] The body frame of the vehicle will be provided with door sill structures on both sides of the bottom of the passenger compartment, and front and rear cross members are respectively provided on the front and rear sides of the bottom of the passenger compartment, that is, the door sill structure on both sides and the front cross beam and The rear beams on the rear side collectively define the area at the bottom of the passenger compartment. Correspondingly, the floor installed on the body frame can be connected with the sill structure, the front cross beam and the rear cross beam. [0003] Specifically, the floor can be covered and overlapped on the door sill structure, the front cross beam and the rear cross beam, and fixed on the door sill structure, the front cross beam and the rear cross beam by means...
