The invention provides a middle frame assembly, an automobile body front structure and an automobile. The middle frame assembly comprises a middle frame front cross beam, a middle frame rear cross beam and a middle frame connecting piece. The middle frame front cross beam and the middle frame rear cross beam are oppositely arranged in parallel, the two ends of the middle frame front cross beam are used for being connected with two front longitudinal beams, and the two ends of the middle frame rear cross beam are used for being connected with two front longitudinal beams; the first end of the middle frame connecting piece is connected with the middle frame front cross beam, and the second end of the middle frame connecting piece is connected with the middle frame rear cross beam. According to the front longitudinal beam, the two front longitudinal beams are connected through the middle frame front cross beam and the middle frame rear cross beam, the problem that the torsional deformation resistance of the front longitudinal beams is poor due to the large front-back span in the horizontal direction is solved, and the torsional deformation resistance of the front longitudinal beams is improved.
本发明提供了一种中部框架组件、车身前部结构及汽车,该中部框架组件包括中部框架前横梁、中部框架后横梁和中部框架连接件;所述中部框架前横梁和所述中部框架后横梁平行相对设置,所述中部框架前横梁的两端用于与两个前纵梁相连,所述中部框架后横梁的两端用于与两个前纵梁相连;所述中部框架连接件的第一端与所述中部框架前横梁相连,所述中部框架连接件的第二端与所述中部框架后横梁相连。本发明中,使两个前纵梁之间通过中部框架前横梁和中部框架后横梁连接,解决了前纵梁在水平方向上由于前后跨度大从而抗扭转变形的能力较差的问题,提高前纵梁的抗扭转变形的能力。
