The invention provides a lower vehicle body integration system, a lower vehicle body and a new energy vehicle, and relates to the technical field of battery system structure integration. The lower vehicle body integrated system comprises a liquid cooling assembly and a vehicle body frame, a liquid outlet component and a liquid inlet component are arranged in a first area, located at the edge position, of the bearing plate surface of the liquid cooling assembly; the vehicle body frame covers the bearing plate surface to define a containing space; the liquid outlet component and the liquid inlet component are located on the side, away from the containing space, of the vehicle body frame. According to the technical scheme, the technical problem that in the prior art, due to the fact that a space for containing a liquid cooling plate pipeline and an operation space for installing the liquid cooling plate pipeline are reserved in a middle lower vehicle body frame, the space for containing an energy assembly in a sealed space becomes small, and the energy density of a system is limited can be solved.

    本申请提供一种下车体集成系统、下车体以及新能源汽车,涉及电池系统结构集成技术领域。其中,一种下车体集成系统,包括:液冷组件以及车体框架;所述液冷组件的承载板面位于边缘位置的第一区域设置有出液部件和进液部件;所述车体框架盖合于所述承载板面上围合构成容纳空间;其中,所述出液部件和所述进液部件位于所述车体框架远离所述容纳空间的侧部。本申请技术方案能够解决现有技术中由于在中部下车体框架中预留出容纳液冷板管线的空间和用于安装液冷板管线的操作空间,如此则使密封空间内用于容纳能源组件的空间变小,限制了系统的能量密度的技术问题。
