Abstract: The present disclosure relates to a full-load passenger car body structure including a roof frame, a side wall frame, a rear frame and an underframe. The side wall frame is enclosed to form an accommodating space, the roof frame is disposed on an upper part of the side wall frame, and the underframe is disposed on a lower part of the side wall frame, where a plurality of reinforcing members are disposed on the underframe and used for reinforcing connection strength of the underframe. Therefore, the connection strength of the underframe is reinforced by disposing the plurality of reinforcing members on the underframe, thereby increasing the strength of the full-load passenger car body structure, and the structure is simple and light without reinforcement, so that the overall weight of the full-load passenger car body structure can be reduced while meeting the requirements for carrying capacity of the underframe.

Abstract: A composite material carrying structure applied to motor vehicles includes a frame, an exterior composite material panel, an interior composite material panel overlapped with the exterior composite material panel and wrapping the frame together with the exterior composite material panel, and an R-corner outer frame, overlapped on the exterior composite material panel, and on which the interior composite material panel is overlapped. The end of the R-corner outer frame and the end of the exterior composite material panel are bent oppositely and fitted, so that a flow direction of water is effectively guided during drenching, and the waterproof effect is improved. With the frame wrapped by the interior and exterior composite material panels, the overall effect of strengthening a car body is achieved, stress of the car body is effectively shared, the light weight of the car body is improved, and energy consumption is reduced.
