The invention belongs to the field of new energy automobile chassis and rear auxiliary frames, and particularly relates to a new energy automobile rear auxiliary frame of a three-dimensional structure, which is used for being installed on a new energy automobile. A cross beam combination mode that high-strength tubular beams are arranged above and below longitudinal beams in a crossing mode and the bending radian sections of cross beams are arranged to be n-shaped is adopted, the weight of the rear auxiliary frame is reduced, meanwhile, the battery arrangement space is increased, and the endurance mileage of a new energy automobile is increased. The combined side frame beams are arranged on the two sides of the top of the main beam and the two sides of the top of the main beam, and after a pair of combined side frame beams is arranged on the combined top of the main beam, the included angle of the top inclined bend of the main beam of the combined side frame beams is 30-90 degrees; an ascending cross beam is arranged at the head end of the main beam, and a descending cross beam is arranged at the tail end of the main beam; the combined side frame beam comprises a left side beam frame and a right side beam frame which are combined with the main beam in a matched lap joint mode, the left side beam frame and the right side beam frame are symmetrically arranged, and the combined side frame beam is connected with the left side beam frame and the right side beam frame in a combined mode.
本发明属于新能源汽车底盘和后副车架领域,具体涉及一种立体结构的新能源车后副车架,用于安装在新能源汽车上。是采用高强度管梁在纵梁的上下进行跨越设置的和横梁弯折弧度截面都设置为∩型的横梁结合形式,减轻后副车架重量的同时增加电池布置空间,提高新能源汽车续航里程。主梁和主梁顶部两侧设置的组合侧架梁,其组合顶部设置一对组合侧架梁后,所述组合侧架梁主梁的顶倾弯的夹角为30°‑90°;并且与主梁相连,并向前方延伸至头端设置上行横梁,尾端设置下行横梁;所述组合侧架梁包括和主梁配合搭接组合的左侧侧梁架和右侧侧梁架,左侧侧梁架和右侧侧梁架对称设置,所述组合侧架梁与所述左侧侧梁架和右侧侧梁架可组合连接。
