The invention relates to a front cabin frame, an automobile body frame and an automobile. The front cabin frame comprises a bottom frame and an upper frame, the bottom frame comprises a plurality of longitudinal beams, a plurality of transverse beams and a load dispersing structure, the longitudinal beams and the transverse beams are arranged in a crossed mode, and the load dispersing structure is connected with all the longitudinal beams and used for being connected to the passenger cabin frame. The longitudinal beams, the transverse beams and the load dispersing structure jointly define a plurality of frame-shaped bottom energy absorption frames. The upper frame comprises a plurality of supporting beams and a vibration reduction reinforcing structure, the supporting beams are connected to the intersections of the longitudinal beams and the transverse beams in a one-to-one correspondence mode, the other ends of the supporting beams are connected to the vibration reduction reinforcing structure, and the vibration reduction reinforcing structure is used for being connected to a passenger compartment frame. The supporting beams, the cross beams and the vibration reduction reinforcing structures jointly define a plurality of frame-shaped upper energy absorption frames. According to the forecabin frame, the force transmission path and the load transmission mode of the forecabin frame are optimized, passengers and the battery pack are protected, and meanwhile the lightweight design of the whole automobile body is facilitated.
本申请涉及一种前舱架、车身框架及汽车。前舱架包括底部框架以及上部框架,其中底部框架包括多条纵梁、多条横梁以及载荷分散结构,各纵梁与各横梁相交设置,载荷分散结构连接所有纵梁,载荷分散结构用于连接至乘员舱架。各纵梁、各横梁与载荷分散结构共同围合形成多个框形的底部吸能框。上部框架包括多条支撑梁以及减振加强结构,各支撑梁的一一对应地连接至各纵梁与各横梁的相交处,各支撑梁的另一端均连接至减振加强结构,减振加强结构用于连接至乘员舱架,各支撑梁、各横梁与减振加强结构共同围合形成多个框形的上部吸能框。上述前舱架优化了前舱架力的传递路径和载荷传递方式,在保护乘员和电池包的同时有利于车身整体的轻量化设计。
