The invention discloses a spine central keel full-bearing vehicle body, wherein the central keel comprises a driver zone floor framework, a front suspension zone framework, a middle piece framework, a rear suspension zone framework and an engine zone framework; the middle piece framework comprises a passenger floor framework, a storage room floor framework and a framework for connecting an upper floor and a lower floor; and the framework for connecting the upper floor and the lower floor is a planar frame which is composed of an upper beam, a lower beam, a plurality of longitudinal beams and a plurality of inclined struts, and the longitudinal beams and the inclined struts are arranged between the upper beam and the lower beam. In the invention, the frameworks symmetrically arranged on both sides of the keel are moved towards the middle to combine a planar trussed construction arranged on the left and right symmetric surfaces of the vehicle body, thus the truss arranged on the left and right symmetric surfaces of the vehicle body has no influence on the volume of the middle piece storage room with left and right openings no matter the inclined struts are provided or not. Therefore, the strength, the rigidity and the security of the vehicle body are greatly enhanced, and the utilization ratio is improved.
