The present invention provides a passenger car back longitudinal beam structure which can establish an effective coherent force transmission path, facilitates the force transmission at direct impact and bias impact, also can slow the deformation of a passenger compartment at the side impact and column impact, and enables the torsional rigidity and bending rigidity of a whole car to be improved. The back longitudinal beam structure comprises a back longitudinal beam body, and the front end of the back longitudinal beam body is a connecting part. The keys are that the front end of the connecting part is a U-shaped groove used for fixing to a front floor longitudinal beam, the cross section main body at the back end of the connecting part is L-shaped, and a side vertical edge used for supporting a middle floor assembly and a side winged edge used for fixing to a doorsill back segment are arranged at the two sides of the back end of the connecting part respectively.
