The invention belongs to the technical field of new energy automobile frames, and particularly relates to a combined longitudinal beam type integrated aluminum alloy frame which comprises a main longitudinal beam and two auxiliary longitudinal beams arranged on the two sides of the main longitudinal beam and further comprises two special-shaped outer edge longitudinal beams arranged on the two sides of the main longitudinal beam. The two auxiliary longitudinal beams are arranged between the two special-shaped outer edge longitudinal beams, the two ends of the two special-shaped outer edge longitudinal beams are integrally bent to form straight parts, and the two ends of the two auxiliary longitudinal beams are fixedly connected with the two straight parts of the special-shaped outer edge longitudinal beams on the same side. The assembly convenience of the frame can be improved, the bearing capacity of the outer edge of the frame and the overall structural stability can be enhanced, the weight of the frame can be reduced, meanwhile, heat dissipation of the battery units can be assisted, energy consumption is reduced, and detection of the welding airtightness of the frame and detection of the structural stability are facilitated.
本发明属于新能源汽车车架技术领域,尤其是涉及一种组合纵梁式一体化铝合金车架,包括主纵梁和设置在主纵梁两侧的两个副纵梁,还包括:两个异形外缘纵梁,两个异形外缘纵梁设置在所述主纵梁的两侧,且两个副纵梁设置在两个异形外缘纵梁之间,两个所述异形外缘纵梁的两端均一体弯折形成平直部,两个副纵梁的两端均与同侧异形外缘纵梁的两个平直部固定连接。本发明可以提高车架组装便捷性,且可以增强车架外缘承重能力和整体结构稳定性、降低车架重量,同时还可以辅助电池单元散热减少能耗、方便检测车架焊接气密性及检查结构稳定性。
