The invention provides a vehicle body side wall rear structure and a vehicle. The vehicle body side wall rear structure according to the present invention comprises: a rear wheel cover inner panel; a side inner panel abutting the rear wheel cover inner panel and at least partially surrounding the rear wheel cover inner panel; the reinforcing piece comprises a reinforcing piece body and at least one supporting rib; wherein the stiffener body is connected to the side wall inner panel, and the at least one support rib extends from the stiffener body and is connected to the rear wheel cover inner panel to provide support between the side wall inner panel and the rear wheel cover inner panel. The vehicle comprises the vehicle body side wall rear structure. According to the vehicle body side wall rear structure and the vehicle, the dynamic stiffness of the rear wheel cover inner plate and the components around the rear wheel cover inner plate is improved through the reinforcing piece, then the dynamic stiffness of the rear suspension shock absorber installation portion of the rear wheel cover inner plate is improved, vibration and noise caused by impact loads can be reduced, and the NVH performance of the vehicle is improved.

本发明提供了一种车身侧围后部结构及车辆。根据本发明的车身侧围后部结构包括：后轮罩内板；侧围内板，该侧围内板邻接后轮罩内板并且至少部分地围绕后轮罩内板；加强件，该加强件包括加强件本体和至少一个支撑肋；其中，加强件本体连接至侧围内板，至少一个支撑肋从加强件本体延伸并且连接至后轮罩内板以在侧围内板与后轮罩内板之间提供支撑。根据本发明的车辆包括该车身侧围后部结构。根据本发明的车身侧围后部结构及车辆中的后轮罩内板以及后轮罩内板周围的部件的动刚度通过加强件得以提高，进而提高了后轮罩内板的后悬架减震器安装部处的动刚度，有助于减少冲击载荷引起的振动和噪音，改善车辆的NVH性能。
