The vehicle body rear frame comprises a first cross beam, a pair of first connecting beams arranged in the transverse direction of a vehicle body at intervals and a pair of first longitudinal beams arranged in the transverse direction of the vehicle body at intervals, and the front ends of the pair of first longitudinal beams are used for being connected with the rear ends of upper edge beams on the corresponding sides of the vehicle body correspondingly; the rear ends of the pair of first longitudinal beams are connected with the two ends of a first cross beam through corresponding first connecting beams respectively, and the first cross beam is a lower cross beam used for limiting an opening of a trunk of a vehicle body. The first connecting beam, the first cross beam and the first longitudinal beam are connected with the upper edge beam of the automobile body, the automobile body rear portion and the automobile body front portion can be connected into a whole, the left side and the right side of the automobile body rear portion are connected into a whole, and the rigidity and the structural strength of the whole automobile body rear portion can be improved. The problems of more local modes, abnormal sound, easy vibration, ear pressure of rear passengers, loud noise and other NVH (Noise Vibration and Harshness) related problems caused by poor rigidity and structural strength of the rear part of the vehicle body can be solved.
本公开涉及一种车身后部框架及车辆,该车身后部框架包括第一横梁、沿车身的横向间隔布置的一对第一连接梁及沿车身横向间隔布置的一对第一纵梁,一对第一纵梁的前端分别用于与车身的对应侧的上边梁的后端相连,一对第一纵梁的后端分别通过对应的第一连接梁与第一横梁的两端相连,其中,第一横梁为用于限定出车身后备箱开口的下横梁。第一连接梁、第一横梁、第一纵梁与车身的上边梁相连,可以将车身后部与车身前部连为一体,并将车身后部的左侧与右侧连为一体,可以提升整个车身后部的刚度及结构强度,有利于解决因车身后部刚度及结构强度差而产生的存在较多局部模态、异响问题、容易振动、后排乘客耳压问题、噪声大等NVH相关问题。
