The invention relates to a modular bumper skeleton structure and a bumper assembly. The modular bumper skeleton structure comprises a middle protective skeleton, the first step framework is fixed to the middle protection framework and two lamp frameworks, and the two lamp frameworks are distributed on the two sides of the middle protection framework at intervals in the width direction of a vehicle body and fixed to the middle protection framework; the lower protection framework is fixed to the bottoms of the two lamp frameworks in the height direction of the vehicle body. The bumper framework structure adopts the design of the left section, the middle section and the right section, namely the multi-section type design, so that all parts under the bumper framework structure are convenient to modularly replace, the part universality rate is good, when local parts of the bumper framework are damaged, replacement and maintenance are convenient, and the maintenance cost is low; meanwhile, the first step framework can be designed in a differentiated mode, it is guaranteed that the framework structure of the non-step area can be universalized, and a welding structure of a traditional bumper framework structure is omitted.
本发明涉及一种模块化保险杠骨架结构及保险杠总成,其包括:中部防护骨架;第一踏步骨架,所述第一踏步骨架固定于所述中部防护骨架两个灯具骨架,在车身宽度方向上,两个所述灯具骨架间隔分布在所述中部防护骨架的两侧,并与所述中部防护骨架固定;下部防护骨架,在车身高度方向上,所述下部防护骨架固定在两个所述灯具骨架的底部。本发明将保险杠骨架结构采用左中右三段设计,即多段式设计,使保险杠骨架结构下的各个零件均便于模块化替代,零件通用率好,在保险杠骨架局部的零部件发生损坏时,方便更换维护,其维护成本低;同时第一踏步骨架可以差异化设计,保证非踏步区域骨架结构可以通用化,取消了传统的保险杠骨架结构的焊接结构。
