A combined longitudinal beam of an aluminum alloy frame is composed of a front longitudinal beam, a rear longitudinal beam and connecting insertion plates, the front longitudinal beam and the rear longitudinal beam are staggered and offset in the transverse direction and form an overlapping combination area in the longitudinal direction, the two side edges of the upper connecting insertion plate and the lower connecting insertion plate are inserted into connecting grooves in the side faces of the front longitudinal beam and the rear longitudinal beam in the overlapping area respectively and are welded and fixed, and the combined longitudinal beam is formed. The two longitudinal beam combination structures are adopted for connection, after the two longitudinal beam combination structures are further combined with a battery compartment on the frame, the overall structural rigidity is high, manufacturing is easy, and the offset distance between the front longitudinal beam and the rear longitudinal beam can be flexibly adjusted to adapt to different chassis plate spring positions.

    铝合金车架组合式纵梁,由前纵梁、后纵梁和连接插板组成,前纵梁和后纵梁在横向错开偏置,并在纵向形成一段重叠组合区,在重叠区分别将上下连接插板的两侧边插入前纵梁和后纵梁的侧面上的连接槽内并焊接固定,形成组合式纵梁。本发明采用两段纵梁组合结构进行连接,与车架上的电池舱进一步组合后,整体结构刚度高,制造简单,前后纵梁之间的偏距可灵活调整以适应不同的底盘板簧位置。
