The invention relates to the technical field of automobile structure design, in particular to a doorsill assembly and an automobile, and the doorsill assembly comprises a front doorsill structure and a rear doorsill structure; the rear doorsill structure comprises a rear doorsill inner plate which is arranged in a shape like a Chinese character'ji 'and is connected with a floor of an automobile; the rear doorsill reinforcing plate is connected to the end part of the rear doorsill inner plate; the sliding door guide rail lower mounting plate is enclosed at the end part of the rear doorsill inner plate; and one end of the sliding door guide rail upper mounting plate is enclosed at the end part of the rear doorsill reinforcing plate, and the other end of the sliding door guide rail upper mounting plate is connected with the sliding door guide rail lower mounting plate, so that the rear doorsill structure forms a closed box-shaped mounting structure. The doorsill assembly has the following technical effects that the first cavity of the front doorsill structure and the second cavity of the rear doorsill structure are of a relatively continuous structure, collision force at the front portion can be effectively transmitted to the rear portion, and the effects of absorbing energy, dispersing impact force, increasing the overall structural strength and keeping balanced response are achieved; and the collision safety can be ensured.

    本发明涉及用于汽车结构设计技术领域,尤其涉及一种门槛组件及汽车,门槛组件包括前门槛结构和后门槛结构;后门槛结构包括:后门槛内板,后门槛内板呈几字形设置,并和汽车的地板连接;后门槛加强板,连接在后门槛内板的端部;滑门导轨下部安装板,围合在后门槛内板的端部;滑门导轨上部安装板,一端围合在后门槛加强板的端部,另一端和滑门导轨下部安装板相互连接,以使后门槛结构形成了一个封闭的盒型安装结构。该门槛组件具备以下技术效果:前门槛结构的第一腔体和后门槛结构的第二腔体是一个相对连续的结构,在前部的碰撞力能够通过有效的向后部传递,起到了吸能、分散冲击力、增加整体结构强度和保持均衡响应的作用,能够保证碰撞的安全。
