The invention provides a roof side rail structure, an automobile body and an automobile, and relates to the field of automobile body structural design, the roof side rail structure comprises a roof side rail inner plate, a roof side rail outer plate and a variable cross-section reinforcer, the roof side rail inner plate and the roof side rail outer plate are installed in a matched mode, and the variable cross-section reinforcer is arranged between the roof side rail inner plate and the roof side rail outer plate; the variable cross-section reinforcer is used for extending in the front-back direction of the automobile, the outer wall of the variable cross-section reinforcer, the roof side rail inner plate and the roof side rail outer plate form a first reinforcing cavity, and the variable cross-section reinforcer is hollow to form a second reinforcing cavity. According to the scheme, the variable cross-section reinforcing piece is arranged between the roof side rail inner plate and the roof side rail outer plate, the variable cross-section reinforcing piece plays a role of a partition piece while playing a reinforcing role, reinforcing cavities are formed in the inner portion and the outer portion of the variable cross-section reinforcing piece respectively, and therefore the reinforcing effect of the variable cross-section reinforcing piece is improved. And the multi-dimensional bending resistance and pressure resistance of the whole roof side rail structure are improved through the double-cavity structure.

    本发明提供了一种上边梁结构、车身及汽车,涉及汽车车身结构设计领域,上边梁结构包括上边梁内板、上边梁外板及变截面加强件,上边梁内板与上边梁外板配合安装,变截面加强件设于上边梁内板与上边梁外板之间,变截面加强件用于沿汽车的前后方向延伸设置,变截面加强件的外壁与上边梁内板、上边梁外板形成第一加强腔,变截面加强件的内部中空设置以形成第二加强腔。本发明所述方案,通过在上边梁内板与上边梁外板之间设置变截面加强件,变截面加强件在起到本身所带来的加强作用的同时,还起到分隔件的作用,变截面加强件的内、外部分别形成加强腔,通过双空腔结构提升整个上边梁结构多维度的抗弯和抗压能力。
