The invention provides a rear floor frame structure and a vehicle. The rear floor frame structure comprises a rear longitudinal beam, a C ring assembly and a rear shock absorber mounting component; the C-ring assembly comprises a rear supporting piece, a rear wheel cover cross beam and a C-ring structure, the C-ring structure is connected with the rear longitudinal beam, the rear supporting piece and the C-ring structure are arranged in a spaced mode, one end of the rear supporting piece is connected with the rear longitudinal beam, the other end of the rear supporting piece forms a connecting part used for being connected with the upper portion of a vehicle body, and the rear wheel cover cross beam is connected between the rear supporting piece and the C-ring structure; the rear shock absorber installation assembly is installed on the rear longitudinal beam and connected with the C ring assembly. According to the rear floor frame structure, two force transmission paths of the rear supporting piece and the rear wheel cover cross beam are added, the Z-direction rigidity of the rear floor frame structure is improved, the rear shock absorber installation assembly is installed on the rear longitudinal beam and connected with the C-ring assembly, the supporting rigidity of the rear floor frame structure is effectively improved, and therefore it is guaranteed that the rear floor frame structure has high operation stability, NVH and durability.
本公开提供了一种后地板框架结构及车辆。后地板框架结构包括后纵梁、C环总成及后减震器安装组件;C环总成包括后支撑件、后轮罩横梁以及C环结构,C环结构与后纵梁连接,后支撑件与C环结构间隔设置,且后支撑件的一端与后纵梁连接,另一端部形成用于与车身上部连接的连接部,后轮罩横梁连接在后支撑件与C环结构之间;后减震器安装组件安装在后纵梁上,且后减震器安装组件与C环总成连接。增加了后支撑件和后轮罩横梁两条传力路径,提高了后地板框架结构的Z向刚度,且后减震器安装组件安装在后纵梁上,并与C环总成连接,有效提升了后地板框架结构的支撑刚度,从而保证了后地板框架结构具有较强的操稳、NVH和耐久性能。
