The invention discloses an automobile cabin frame structure which comprises a front anti-collision beam assembly, a cabin longitudinal beam assembly, an A column assembly, a cabin upper edge beam assembly and a front wall reinforcing cross beam assembly. The collision energy is dispersed to the A column assembly through the longitudinal beam stand column and the cabin upper edge beam assembly on the front section of the cabin longitudinal beam, and the collision energy transmitted to the rear section of the cabin longitudinal beam from the front section of the cabin longitudinal beam is dispersed and transmitted to the A column assembly and the other side of the vehicle body through the front wall reinforcing middle cross beam and the front wall reinforcing bottom cross beam. Therefore, the engine room longitudinal beam rear section area frame is stable. The invention further discloses an automobile with the automobile cabin frame structure. According to the automobile cabin frame structure and the automobile, a collision force transmission structure is optimized, and the small offset collision performance is improved; the structure is simple and light, and the manufacturing cost is reduced.

    本发明公开了一种汽车机舱框架结构,包括:前防撞梁总成、机舱纵梁总成、A柱总成、机舱上边梁总成以及前围加强横梁总成,机舱框架与壁障在碰撞工况中产生碰撞能量,该碰撞能量在机舱纵梁前段通过纵梁立柱和机舱上边梁总成分散至A柱总成,由机舱纵梁前段传递至机舱纵梁后段的碰撞能量分别通过前围加强中横梁和前围加强底横梁向A柱总成及车身的另一侧分散传递,以使机舱纵梁后段区域框架的稳定。本发明还公开了一种具有上述汽车机舱框架结构的汽车。实施本发明汽车机舱框架结构、汽车,优化碰撞传力结构,提升小偏置碰性能;结构精简,轻量化,降低制造成本。
