The impact-resistant roof side rail assembly comprises a roof side rail structure, a cross beam structure, a reinforcing structure and an energy absorption structure, the reinforcing structure comprises a first reinforcing frame, a second reinforcing frame and a third reinforcing frame which are all hollow, the first reinforcing frame is fixedly connected to the inner arc face of the cross beam structure, and the second reinforcing frame is fixedly connected to the inner arc face of the cross beam structure; the second reinforcing frame is fixedly connected to the inner arc surface of the column B, and the third reinforcing frame is fixedly connected to the inner arc surface of the roof side rail structure; the energy absorption structure comprises a first energy absorption plate, a second energy absorption plate and a third energy absorption plate, and the first energy absorption plate, the second energy absorption plate and the third energy absorption plate are all designed to be in a corrugated paper texture shape. According to the roof side rail assembly, the impact strength of the roof side rail assembly is further enhanced, energy absorption and buffering can be continuously conducted on follow-up impact force after displacement of the pressing plate occurs, the follow-up displacement of the pressing plate is reduced, and the protection performance is better.
本发明公开了耐冲击的上边梁总成,包括上边梁结构、横梁结构、加强结构以及吸能结构,所述加强结构包括第一加强框架、第二加强框架以及第三加强框架且均为中空设置,第一加强框架固定连接在横梁结构的内弧面上,第二加强框架固定连接在B柱的内弧面上,第三加强框架固定连接在上边梁结构的内弧面上;所述吸能结构包括第一吸能板、第二吸能板以及第三吸能板,且第一吸能板、第二吸能板和第三吸能板均设计为瓦楞纸纹理状。本发明不仅进一步加强了上边梁总成的抗冲击强度,而且在出现压板位移后,能继续对后续的冲击力进行吸能缓冲,减少了后续的压板位移量,保护性能更佳。
