The utility model relates to an edge longitudinal beam of an aluminum alloy vehicle body, which comprises an edge longitudinal beam body, a hollow bulge is arranged at the upper part of an inner side plate of the edge longitudinal beam body, and the bulge is positioned on the wall surface of the inner side plate, which is used for connecting a floor cross beam; and an outer side plate of the edge longitudinal beam body comprises an upper side plate and a lower side plate which are arranged up and down and connected, and the distance between the upper side plate and the inner side plate is smaller than the distance between the lower side plate and the inner side plate. The problem that the lap joint relation between the threshold beam and surrounding environment pieces such as the column A, the column B, the column C and/or the floor cross beam (such as a front floor front cross beam, a front floor rear cross beam and a rear floor front cross beam) cannot be well considered in the prior art can be solved.
本申请涉及一种铝合金车身的边纵梁,其包括边纵梁本体,所述边纵梁本体的内侧板上部设有中空的凸起,所述凸起位于所述内侧板用于连接地板横梁的壁面上;所述边纵梁本体的外侧板包括上下布置且相连的上侧板和下侧板,且所述上侧板到所述内侧板的距离小于所述下侧板到所述内侧板的距离。本申请可以解决相关技术中未能较好地考虑门槛梁与A柱、B柱、C柱和/或地板横梁(如前地板前横梁、前地板后横梁、后地板前横梁)等周边环境件的搭接关系的问题。
