The invention provides a vehicle frame body, a box girder type vehicle frame assembly and a vehicle, and belongs to the technical field of vehicle chassis frames. The frame body comprises a longitudinal box girder and a top plate; the longitudinal box girders and the top plate are of a sectional material type structure integrally formed through extrusion. The longitudinal box girder is connected to the lower surface of the top plate, and the longitudinal box girder and the top plate define a hollow cavity used for containing a vehicle-mounted component. The longitudinal box girder and the box girder top plate are machined and formed into the highly-integrated integrally-formed structure, the box girder top plate can be directly used as a bottom plate of a container and can also replace a cross beam, the weight of a frame is effectively reduced, the hollow cavity of the longitudinal box girder can be used for containing vehicle-mounted components such as a power battery, the strength of the longitudinal box girder is high, and the vehicle-mounted components are not prone to being damaged. The power battery can be effectively protected, a protective shell does not need to be additionally provided for the power battery, and the requirement for light weight of the whole vehicle can be further met.

    本申请提供一种车架本体、箱梁式车架总成及车辆,属于车辆底盘车架技术领域。车架本体包括纵向箱梁和顶板;纵向箱梁和顶板为挤压一体成型的型材式结构;纵向箱梁连接于顶板的下表面,纵向箱梁和顶板围合形成有用于容纳车载部件的中空腔体。通过将纵向箱梁和箱梁顶板加工成型为高度集成化的一体成型结构,箱梁顶板可以直接作为货箱的底板使用,又可以代替横梁功能,有效降低了车架的重量,纵向箱梁的中空腔体可用于容纳动力电池等车载部件,纵向箱梁的强度较高,可有效保护动力电池,无需为动力电池额外提供防护外壳,可进一步满足整车轻量化要求。
