The invention provides a vehicle body rear reinforcing structure. The vehicle body rear reinforcing structure comprises a polygonal pipe rear wall and a D column, wherein a pipe cavity at the joint of the rear wall and the D column is filled with structural blocks. Therefore, the pipe cavity of the rear wall and the column D can be divided into a plurality of pipe joint structures, the structural strength and torsion resistance of a rear wall are improved, meanwhile, corners with the maximum deformation are filled with the structural blocks, peripheral structural parts are supported and prevented from being excessively deformed, and torsion resistance of the whole vehicle is greatly improved.

    本发明提供一种车身后部加强结构,包括多边形管状的后围及D柱,后围与D柱衔接处的管腔内填充有结构块。这样便能将后围及D柱的管腔分隔为一个个管节结构,提升后围结构强度和抗扭能力,同时在变形量最大的拐角处填充结构块,对周边结构件进行支撑并防止其过度变形,大大提升了整车的抗扭能力。
