The invention relates to a light-weight aluminum alloy fender support assembly which comprises a mounting seat used for being connected with a longitudinal beam of a frame and a support body integrally formed with the mounting seat, the mounting seat comprises a bottom integrally formed with the support body and two corresponding mounting support arms oppositely extending from the two sides of the bottom, and the mounting support arms are arranged on the mounting seat. The mounting support arm is used for being connected with a frame longitudinal beam; the mounting base is of a hollow structure, a first hollow frame strip and a second hollow frame strip extend outwards from the two sides of the mounting base respectively, and the first frame strip and the second frame strip are sequentially connected end to end through a plurality of solid frame strips to form a frame-shaped support body. The mounting seat, the first frame strip and the second frame strip are integrally formed to form a hollow core part, and the total mass of the hollow core part is M1; the plurality of solid frame strips are integrally formed to form a solid part, the total mass of the solid part is M2, and M1 < M2 < 3M1. According to the structure, the modality and the strength are improved while the weight is reduced.

本发明涉及一种轻量化铝合金挡泥板支架总成，包括用于与车架纵梁连接的安装座，以及与安装座一体成型的支架主体，安装座包括与支架主体一体成型的底部、以及自底部的两侧相对延伸出对应的两个安装支臂，安装支臂用于与车架纵梁连接；安装座为空芯结构，自安装座的两侧分别向外延伸有空芯的第一框条、第二框条，在第一框条、第二框条之间通过多条实芯框条依次首尾连接而构成框形的支架主体；安装座、第一框条、第二框条一体成型而构成空芯部分，空芯部分的总质量为M1；多条实芯框条一体成型而构成实芯部分，实芯部分的总质量为M2，且满足M1＜M2＜3M1。该种结构轻量化的同时，提高模态和强度。
