The invention provides a box girder type frame body, a frame assembly and a vehicle. The box girder type frame body is of a section bar type structure which is integrally formed in an extrusion mode. Comprising a cargo floor. And the box girder plate is parallel to the container bottom plate. The longitudinal box girders are connected and arranged between the container bottom plate and the box girder plate, at least three hollow cavities are defined by the longitudinal box girders, the container bottom plate and the box girder plate, and the hollow cavities penetrate through the longitudinal box girders in the longitudinal direction of the vehicle. The longitudinal box girders, the box girder plates and the container bottom plate are machined and formed into the highly-integrated integrally-formed structure, independent cross beams do not need to be arranged in the middle of the frame structure, and the weight of the frame is effectively reduced. The container bottom plate can be directly used as the bottom plate of the container, and the problems that a frame and the container are difficult to assemble and complex to assemble are solved. And the hollow cavity can be used for accommodating vehicle-mounted parts such as a power battery, so that the space of the frame structure is effectively utilized.
本申请提供一种箱梁式车架本体、车架总成及车辆。箱梁式车架本体为挤压一体成型的型材式结构。包括货箱底板。箱梁板,与货箱底板平行设置。纵向箱梁,连接并设于货箱底板和箱梁板之间,纵向箱梁、货箱底板、箱梁板之间围合成至少三个中空腔体,中空腔体沿车辆纵向贯穿纵向箱梁。通过将纵向箱梁、箱梁板和货箱底板加工成型为高度集成化的一体成型结构,不需要在车架结构的中间布置独立横梁,有效降低了车架的重量。货箱底板可以直接作为货箱的底板使用,解决了车架与货箱的装配困难和装配复杂的问题。中空腔体可用于容纳动力电池等车载部件,有效利用车架结构的空间。
