The invention discloses an automobile rear floor structure, which relates to the field of automobile bodies, and comprises a floor body, and a seat lower cross beam, a floor rear cross beam, a floor left front longitudinal beam, a floor right front longitudinal beam and a floor front cross beam which are arranged on the floor body to form a frame structure, the floor body is folded to the floor front cross beam at the position of the seat lower cross beam to form a step, the two sides of the seat lower cross beam are in lap joint with the floor left front longitudinal beam and the floor right front longitudinal beam, and the seat lower cross beam and the floor front cross beam form a front end frame structure. The two sides of the floor rear cross beam at the rear end are also in lap joint with the floor left front longitudinal beam and the floor right front longitudinal beam to form a rear end frame structure. The platform is mainly provided for development of the rear floor of the electric automobile, and the purposes of low manufacturing cost and low design cost are achieved; on the basis of the structure, the process is indirect, the production period is shorter than that of a traditional process, meanwhile, the installation structure of the rear-row seat lower cross beam is added, the structure and the longitudinal beam cooperate to form an outer frame, and the structural rigidity is greatly improved.

    本发明公开了一种汽车后地板结构,涉及汽车车身领域,包括地板本体以及在地板本体上布设出框架结构的座椅下横梁、地板后横梁、地板左前纵梁、地板右前纵梁以及地板前横梁;地板本体在座椅下横梁的位置翻折至地板前横梁形成台阶,座椅下横梁的两侧搭接地板左前纵梁和地板右前纵梁,且与底板前横梁形成前端框架结构;后端的地板后横梁的两侧也搭接地板左前纵梁和地板右前纵梁上,形成后端框架结构。本发明主要为电动汽车的后地板开发提供平台,实现低制造成本,低设计成本的目标;基于结构本身而言,工艺间接,生产周期短于传统工艺,同时增加了后排座椅下横梁的安装结构,该结构与纵梁一起又协同形成外框架,大大提高了结构刚度。
