The invention relates to the technical field of rear vehicle auxiliary frames, and particularly discloses a rear auxiliary frame structure and a vehicle. The left longitudinal beam is arranged on the left side of the front cross beam and fixedly connected with the front cross beam, and a first split type support is arranged on the upper surface of the left longitudinal beam; the right longitudinal beam is arranged on the right side of the front cross beam and fixedly connected with the front cross beam, and a second split type support is arranged on the upper surface of the right longitudinal beam; the rear cross beam is arranged at the rear end of the front cross beam and fixedly connected with the left longitudinal beam and the right longitudinal beam, a splicing support is arranged on the lower surface of the rear cross beam, and the two ends of the splicing support are connected with the lower surface of the left longitudinal beam and the lower surface of the right longitudinal beam respectively. The rear auxiliary frame structure is adaptive to various brackets according to stress states of a plurality of parts, has the advantage of light weight, reduces the production cost, and can meet the requirement of bearing capacity.

    本发明涉及后车辆副车架技术领域,具体公开了一种后副车架结构和车辆,包括:前横梁,上表面设置有U型支架;左纵梁,设于所述前横梁的左侧且与所述前横梁固定连接,所述左纵梁的上表面设置有第一分体式支架;右纵梁,设于所述前横梁的右侧且与所述前横梁固定连接,所述右纵梁的上表面设置有第二分体式支架;和后横梁,设于所述前横梁的后端且所述后横梁分别与所述左纵梁和所述右纵梁固定连接,所述后横梁的下表面设置拼接支架,所述拼接支架的两端分别与所述左纵梁的下表面和所述右纵梁的下表面连接。本发明的后副车架结构根据多个部位的受力状态,适配多种支架,具有轻量化的优势,来降低生产成本,又能够满足承载力的要求。
