The invention relates to a modularized protection type vehicle body framework structure which comprises a lower vehicle body modularized structure and an upper vehicle body modularized structure, and the lower vehicle body modularized structure comprises a front bumper longitudinal beam, a floor framework structure, a longitudinal beam module and at least two power system hanging plate modules. The front bumper longitudinal beam and the floor framework structure are arranged at intervals in the front-back direction, the longitudinal beam module is connected with the front bumper longitudinal beam and the floor framework structure, the at least two power system hanging plate modules are arranged on the longitudinal beam module at intervals in the front-back direction, and the longitudinal beam module is one of a bearing type longitudinal beam module and a non-bearing type longitudinal beam module; the upper vehicle body modular structure is connected to the upper side of the lower vehicle body modular structure, and the upper vehicle body modular structure and the lower vehicle body modular structure jointly form a vehicle body framework. According to the invention, a small part of modular components are replaced to be combined with universal components, so that switching between a bearing type vehicle body structure and a non-bearing type vehicle body structure is realized under the condition that the influence on a vehicle body framework is minimum.

    本发明涉及一种模块化防护型车身骨架结构,包括下车身模块化结构和上车身模块化结构,所述下车身模块化结构包括前保险杠纵梁、地板骨架结构、纵梁模块和至少两个动力系统挂板模块,前保险杠纵梁和地板骨架结构沿前后向间隔布设,纵梁模块连接前保险杠纵梁和地板骨架结构,至少两个动力系统挂板模块沿前后向间隔布设于纵梁模块,其中,纵梁模块为承载式纵梁模块和非承载式纵梁模块中的一个;上车身模块化结构,连接于下车身模块化结构上侧,上车身模块化结构和下车身模块化结构共同构成车身骨架。本发明通过更换小部分模块化部件与通用部件组合实现在对车身骨架影响最小情况下快速在承载式车身结构与非承载式车身结构间切换。
