The invention discloses a white vehicle body frame. An upper surface of a front floor assembly is flush with the upper surface of a rear floor assembly, a concave spare wheel cabin is arranged on themiddle rear portion of the front floor assembly, and an upper left longitudinal beam and an upper right longitudinal beam are fixed to the upper surface of the front floor assembly in a bilateral symmetry mode. The left upper longitudinal beam and the right upper longitudinal beam are respectively arranged corresponding to the front parts of a left beam and a right beam up and down; a cross beam group comprises a first cross beam, a second cross beam and a cross beam outward extending component which are fixed on the lower surface of the front floor assembly and also comprises a spare wheel cabin upper cross beam, a left seat front cross beam, a right seat front cross beam, a left seat rear cross beam and a right seat rear cross beam fixed to the upper surface of the front floor assembly,the outer side of the left beam and the outer side of the right beam are fixedly connected with a threshold inner plate body through cross beam outer extending assemblies respectively. According to the white vehicle body frame, a multi-force-transmission-path frame structure is formed, the collision force is effectively dispersed, the safety performance of a vehicle is improved, the height of thevehicle is reduced, and the wind resistance of the whole vehicle is improved.

    本发明公开了一种白车身框架,前地板总成的上表面与后地板总成的上表面平齐,前地板总成的中后部设有下凹的备胎舱,左上纵梁和右上纵梁左右对称固定于前地板总成的上表面,左上纵梁和右上纵梁分别与左大梁和右大梁的前部位置上下相对应设置,横梁组包括固定于前地板总成下表面上的第一横梁、第二横梁和横梁外延伸组件,以及固定于前地板总成的上表面上的备胎舱上横梁、左座椅前横梁、右座椅前横梁、左座椅后横梁、右座椅后横梁,左大梁的外侧和右大梁的外侧分别通过横梁外延伸组件与门槛内板本体固定连接。本发明的一种白车身框架,形成多传力路径框架结构,有效分散碰撞力,提升车辆安全性能,使车高降低,改善整车风阻。
