The invention relates to the technical field of manufacturing and production of automobiles and auxiliary frames, in particular to a new energy vehicle rear auxiliary frame of a double-layer side beam structure. A double-layer side beam is arranged, the side beam structure is provided with a plurality of impact disengagement-assisting grooves, vehicle body connecting structures are installed in the impact disengagement-assisting grooves, connecting pieces and supports connected to the vehicle body connecting structures can be bent and disengaged in a segmented mode in the vehicle impact process, an engine on a frame body is further helped to sink or be disengaged and fixed more easily in a controlled mode, and the vehicle body connecting structures comprise an upper cross beam, a lower cross beam and a longitudinal beam. Wherein the longitudinal beam comprises an upper beam pipe and a lower beam pipe, the upper beam pipe is arranged above the lower beam pipe, the integrated molding comprises a head vertical pipe, an upper beam body and a tail vertical pipe, the head end of the upper beam body and the head vertical pipe are connected through a bent connecting structure, and the tail end of the upper beam body and the tail vertical pipe are connected through a bent connecting structure. The joints A of the bent connecting structures are provided with concave molded upper beam disengagement assisting grooves, and the upper beam disengagement assisting grooves are provided with upper longitudinal beam support seats; and the lower beam pipe comprises a head bent pipe and a frame seat pipe which are integrally molded.

    本发明涉及汽车、副车架制造和生产技术领域,具体为一种双层侧梁结构的新能源车后副车架。设置双层侧梁,侧梁结构设置有多个撞击助脱槽,撞击助脱槽内安装车身连接结构,在车辆撞击中能分段弯折、脱落连接在自身的连接件和支架,进一步的帮助架体上的引擎更容易被“控制”的下沉或脱离固定,包括上横梁、下横梁、纵梁,其中:所述纵梁包括上梁管、下梁管,所述上梁管设置在下梁管上方,一体塑形包括头立管、上梁本体、尾立管,上梁本体头端和头立管以及上梁本体尾端和尾立管连接都是弯曲连接结构,在弯曲连接结构位置的连接处A都设置有内凹塑形的上梁助脱槽,上梁助脱槽设置上纵梁支架座;所述下梁管包括一体塑形的头弯管和架座管。
