A modularized automobile back row seat framework structure based on performance customization comprises a quartered seat framework structure and a sixth seat framework structure which are arranged side by side, and each of the quartered seat framework structure and the sixth seat framework structure comprises a backrest pipe frame, a limiting stopper and a connecting piece thereof, a seat basin pipe frame, a seat basin connecting transverse beam, a seat basin connecting longitudinal beam, a seat limiting stopper and a connecting piece thereof. According to performance requirements, a variable-strength and variable-thickness pipe frame structure is integrally designed and customized, the four-part seat framework structure and the six-part seat framework structure form a variable-strength structure with the same section and variable-strength distribution, and meanwhile, the seat basin framework adopts an integrated variable-thickness structure; the number of connecting pieces and welding seams is reduced while the performance requirement is met, and weight reduction is achieved; the sextant seat limiter backrest connecting plate is innovatively designed and can be directly inserted into the lower portion of a sextant seat limiter connecting pipe, the structural design requirement is met, and the framework strength is improved; the four-quarter seat backrest pipe frame connecting side plate and the six-quarter seat backrest pipe frame connecting side plate adopt parts with the same structure, share the same cushion connecting plate, are connected with the seat basin connecting cross beam and can independently rotate, and the part cost is reduced; the pipe diameters and the thicknesses of the parts are merged, modular design and maximization of the mold sharing rate are achieved, and modular and lightweight design of the rear-row seat framework is achieved.

    一种基于性能定制的模块化汽车后排座椅骨架结构,包括:并排设置的四、六分座椅骨架结构,四、六分座椅骨架结构分别包括:靠背管框,限位器及其连接件,座盆管框,座盆连接横,纵梁,座椅限位器及其连接件。可根据性能要求,采用变强度与变厚度管框结构一体化设计定制,所述四、六分座椅骨架结构自身形成同截面但强度变化分布的变强度结构,同时座盆骨架采用一体式变厚度结构,在满足性能要求的同时既减少连接件及其焊缝数量又实现减重;六分座椅限位器靠背连接板创新设计,可直接插入六分座椅限位器连接管下方,满足结构设计需求并提升骨架强度;四、六分座椅靠背管框连接边板采用相同结构零件,且共用同一坐垫连接板,与座盆连接横梁相连且可以独立旋转,降低零件成本;零件管径及厚度进行归并,实现模块化设计与最大化模具共用率,实现后排座椅骨架模块化与轻量化设计。
