The invention discloses a floor framework assembly, a floor assembly and a vehicle, and solves the problems that in the prior art, a floor framework assembly is large in part number, large in tool number and large in investment; the manufacturing process is complicated, and the production efficiency is low. The floor framework assembly adopts an integrated design scheme and comprises a framework upper plate assembly and a framework lower plate assembly, and the framework upper plate assembly comprises two longitudinal beam upper plates; the framework lower plate assembly comprises two longitudinal beam lower plates; cross beams of the floor framework assembly can be selectively arranged in the framework upper plate assembly and/or the framework lower plate assembly, the cross beams and corresponding longitudinal beam upper plates/longitudinal beam lower plates are firstly blanked into material plates with proper sizes, and the material plates are integrally formed through hot stamping after being tailor-welded, so that the framework upper plate assembly and the framework lower plate assembly respectively form a single piece, the number of dies is greatly reduced, and the production efficiency is improved. In addition, as the tailor-welded object is the flitch, a large amount of fixture investment is saved, manufacturing procedures are reduced, and production efficiency is improved.

    本申请公开了一种地板骨架总成、地板总成以及车辆,解决现有技术地板骨架总成零件数量多,工装数量很多,投资大;制造工序复杂,生产效率低的技术问题。本申请提供的地板骨架总成采用一体化设计方案,包括骨架上板组成和骨架下板组成,骨架上板组成包括两个纵梁上板;骨架下板组成包括两个纵梁下板;地板骨架总成的横梁可选择设置在骨架上板组成和/或骨架下板组成中,横梁与对应的纵梁上板/纵梁下板先落料成合适尺寸的料板,料板拼焊后通过热冲压一体成型,由此骨架上板组成和骨架下板组成分别形成单件,模具数量大量减少,并且由于拼焊的对象为料板,还节省了大量夹具投资,减少制造工序,提高生产效率。
