The invention provides a vehicle body lower platform modular framework and a vehicle thereof. The vehicle body lower platform modular framework comprises a battery pack module, a power supply module and a power supply module, a front cabin module and a rear cabin module; wherein the battery pack module comprises a battery frame formed by splicing bracket bodies, a battery core body and a high-voltage accessory; the floor is arranged at the top of the battery frame, a mounting cavity is defined by the battery frame and the floor, and the battery core and the high-voltage accessory are arranged in the mounting cavity; the connecting piece comprises bolts and structural adhesive, the bolts are connected with the support body and the front cabin module and connected with the support body and the rear cabin module, and the structural adhesive is coated on the connecting face of the support body and the rear cabin module and the connecting face of the support body and the front cabin module. The bolt is connected with the structural adhesive, so that the connection strength is ensured, and the sealing requirement is met; a front floor assembly is omitted, parts of the automobile are further simplified, and therefore application of auxiliary operation clamps and follow-up processing of accumulated tolerance can be reduced.
本发明提供了一种车体下平台模块化架构及其汽车,车体下平台模块化架构包括:电池包模块,电池包模块上集成有地板;前舱模块与后舱模块;其中,电池包模块包括由支架体拼合成的电池框架、电池芯体以及高压附件;地板设置于电池框架的顶部,电池框架与地板围合成安装腔,电池芯体与高压附件设置在安装腔内;连接件包括螺栓以及结构胶,螺栓连接支架体与前舱模块以及连接支架体与后舱模块,结构胶涂设于支架体与后舱模块的连接面以及支架体与前舱模块的连接面上。通过螺栓与结构胶连接保证连接强度同时又可以达到密封需求;取消了前地板总成,进一步精简了汽车的零部件,从而可减少辅助操作夹具的应用以及累计公差的后续处理问题。
