The invention discloses a modularized vehicle structure. The modularized vehicle structure comprises a vehicle body framework, a vehicle front axle and a vehicle rear axle, and the vehicle front axle and the vehicle rear axle are arranged on the vehicle body framework. The vehicle front axle comprises a front axle body and a front axle suspension. The vehicle rear axle comprises a rear axle body and a rear axle suspension. The rear axle body comprises a front connecting plate, a rear connecting plate and a plurality of longitudinal beams. The front connecting plate is fixedly connected with the rear connecting plate through the multiple longitudinal beams to form an integral cage-like structure. The front axle body comprises a left axle body unit and a right axle body unit, the left axle body unit is formed by fixedly connecting a plurality of connecting plates and longitudinal beams, and the right axle body unit is formed by fixedly connecting a plurality of connecting plates and longitudinal beams. The left axle body unit and the right axle body unit which are symmetrically arranged are connected through a plurality of transverse beams to form an integral cage-like structure. A front axle assembly and a rear axle assembly which are designed in a modularized mode are used for bearing the weight of a vehicle body in the overall vehicle configuration and replacing part of functions of the vehicle body framework, and the passenger vehicle lightweight design is further achieved.
