The invention provides a roof side rail reinforcing structure of an automobile, and belongs to the technical field of machinery. The roof side rail reinforcing structure solves the problem of poor pressure resistance of the top of an existing roof side rail. The roof side rail of the automobile comprises a roof side rail inner plate and a roof side rail outer plate, a cavity is defined between theroof side rail inner plate and the roof side rail outer plate, the reinforcing structure comprises a reinforcing piece, the reinforcing piece is arranged in the cavity, the reinforcing piece is fixedly connected with the roof side rail inner plate and/or the roof side rail outer plate, and the reinforcing piece divides the cavity into at least two reinforcing cavities. The reinforcing piece playsa role of a separator while playing a role of a reinforcing role brought by the reinforcing piece, a plurality of reinforcing cavities are formed, so that the bending resistance and the pressure resistance of the whole roof side rail structure are qualitatively improved, a key load transmission effect can be achieved in top pressure resistance, the pressure resistance can be dispersed to a columnA, a top cover front cross beam and a column B to be transmitted to all positions of an automobile body, and the pressure resistance and the strength grade of the automobile roof are greatly improved.

本发明提供了一种汽车的上边梁加强结构，属于机械技术领域。它解决了现有的上边梁顶部抗压力差的问题。本汽车的上边梁包括上边梁内板和上边梁外板，上边梁内板和上边梁外板之间合围形成腔体，本加强结构包括加强件，加强件设置在腔体内，加强件与上边梁内板和/或上边梁外板相固连，且加强件将腔体分隔为至少两个加强腔。加强件在起到本身所带来的加强作用的同时又起到了一个分隔件的作用，从而形成多个加强腔，使得整个上边梁结构的抗弯和抗压能力得到了质的提升，能够在顶部抗压中起着关键的载荷传递作用，从而能够将抗压力分散到A柱、顶盖前横梁、B柱传递到车身各个位置极大的提高了车顶的抗压能力和强度等级。
