The invention relates to a vehicle body frame and a vehicle using the same. The vehicle body frame comprises side longitudinal beams, and side wall stand columns, and the upper ends of the side wall stand columns are connected with the side longitudinal beams; the vehicle body frame further comprises top cross beams, and the top cross beams and the side wall stand columns are arranged in the same vertical plane, and the ends of the top cross beams are connected with the side longitudinal beams; the vehicle body frame further comprises reinforcing connecting pieces which are arranged at the joints of the side longitudinal beams, the side wall stand columns and the top cross beams and are fixedly connected with the side longitudinal beams, the side wall stand columns and the top cross beams; the reinforcing connecting pieces comprise groove-shaped plates, and a closed cavity is defined by the groove-shaped plates, the top cross beams, the side longitudinal beams and/or the side wall stand columns. And a space three-dimensional structure is formed at the intersection of the side longitudinal beams, the top cross beams and the side wall stand columns. The reinforcing connecting pieces are connected with the top cross beams, the side longitudinal beams and the side wall stand columns at the same time, loads borne by the top cross beams can be dredged and dispersed to the side longitudinal beams and the side wall stand columns through the reinforcing connecting pieces, the contact area is increased, and the effects of reducing local stress and improving rigidity are achieved. Compared with a thin plate body, the stability of the spatial three-dimensional structure is higher, and deformation is not prone to occurring.

    本发明涉及一种车身骨架及使用该车身骨架的车辆。车身骨架包括:边纵梁;侧围立柱,上端与边纵梁相连;顶横梁,与侧围立柱设于同一竖直面内,端部与边纵梁相连;加强连接件,设于边纵梁、侧围立柱、顶横梁的连接处,且与边纵梁、侧围立柱及顶横梁均固定相连;加强连接件包括槽型板,槽型板、顶横梁以及边纵梁和/或侧围立柱合围形成封闭的空腔。边纵梁、顶横梁和侧围立柱的相交处形成了空间立体结构。加强连接件同时与顶横梁、边纵梁和侧围立柱相连,顶横梁受到的载荷可以通过加强连接件疏导分散至边纵梁和侧围立柱处,增大接触面积并起到降低局部应力、提升刚度的作用。相比单薄的板体而言,空间立体结构的稳定性更强,不易发生变形。
