The invention provides a limousine spare wheel basin supporting plate and a rear floor beam frame assembly and relates to the technical field of car body structures. The limousine spare wheel basin supporting plate comprises a supporting plate body plate arranged in the vertical direction of a car, a welding flange and a welding gear. The welding flange and the welding gear are attached to a rear floor horizontal beam and a spare wheel basin along the periphery of the body plate in a welding mode. The limousine spare wheel basin supporting plate is placed between the spare wheel basin and the rear floor horizontal beam and has a connecting effect, the limousine spare wheel basin supporting plate is used for enhancing the structure intensity of a spare wheel basin zone, supporting on a spare wheel is improved, influence on sitting comfort due to vibration of the spare wheel during limousine running is lowered, and car NVH performance is improved. Meanwhile, when a rear-end collision accident happens to a car, the limousine spare wheel basin supporting plate can induce structure deforming of a car trunk zone, deforming of a back row passenger compartment is lowered, and sufficient surviving space of a back row passenger during a car rear-end collision accident is guaranteed. In addition, through the structure design of the limousine spare wheel basin supporting plate, hard structure squeezing of a car fuel tank during the car rear-end collision accident can be avoided, and the limousine safety is further improved. The structure is firm in structure, formability is good, welding and locating are accurate, welding is convenient, and the production efficiency of cars is not affected.
