The invention provides a vehicle body lightweight substructure, a connecting device and a lightweight vehicle body, and belongs to the technical field of vehicle lightweight. The supporting pieces are arranged in the outer shell and integrally formed with the outer shell, and gaps exist between the supporting pieces and a shell body of the outer shell and between the adjacent supporting pieces. While the strength of the vehicle body is guaranteed, the vehicle body assembling efficiency is improved, the vehicle body weight is reduced, and vehicle body light weight is achieved.

    本发明提出一种车身轻量化子结构、连接装置及轻量化车身,属于整车轻量化技术领域,包括:外壳,外壳为铝合金结构;支撑件,支撑件为若干个,且支撑件设置在外壳内与外壳一体成型,支撑件与外壳的壳体之间和相邻支撑件之间存在有间隙。本发明能够在保障车身强度的同时,提高车身装配效率,减轻车身重量,实现车身轻量化。
