The invention relates to the technical field of new energy vehicles, and provides a lower vehicle body platform of a new energy vehicle, which comprises a cabin module, a battery bearing module and a rear floor framework module, a rear floor front cross beam module is arranged between the battery bearing module and the floor framework module; floor side plate modules are arranged on the two sides of the rear floor framework module. The battery bearing module comprises a central channel module, a first front floor and a second front floor, the first front floor and the second front floor are arranged on the two sides of the central channel module, a first threshold beam is arranged on one side of the first front floor, and a second threshold beam is arranged on one side of the second front floor. Through the modular design, when the wheelbase is adjusted, only the rear floor front cross beam module needs to be adjusted, the vehicle type with the wheelbase changed can be achieved, other module assemblies can share and adapt, when the wheelbase is adjusted, only the central channel module and the floor sideboard module need to be adjusted, and other module assemblies can share and adapt. And the development cost of different vehicle types is reduced, and the resource utilization efficiency is improved.

    本发明涉及新能源汽车的技术领域,提供一种新能源汽车的下车体平台,包括机舱模块、电池承载模块和后地板骨架模块;电池承载模块与地板骨架模块之间设有后地板前横梁模块;后地板骨架模块两侧设有地板边板模块;电池承载模块包括中央通道模块、第一前地板和第二前地板,第一前地板和第二前地板设于中央通道模块两侧,第一前地板一侧设有第一门槛梁,第二前地板一侧设有第二门槛梁。通过模块化设计,在轴距进行调整时仅需要调整后地板前横梁模块就可以实现轴距变化得车型,而其他模块组件则能够共享适配,在轮距进行调整时仅需要调整中央通道模块和地板边板模块,其他设于模块组件则能够共享适配,降低了不同车型得开发成本,提高资源利用效率。
