Abstract

The invention relates to the technical field of automobile bodies and discloses an automobile body rear floor frame structure. The automobile body rear floor frame structure comprises a rear wheel casing, a rear floor crossbeam and a rear longitudinal beam. The rear longitudinal beam comprises a rear longitudinal beam front section and a rear longitudinal beam rear section. The rear longitudinal beam front section comprises a rear longitudinal beam front section body and a joint structure connected with the rear longitudinal beam front section body, and the rear longitudinal beam front sectionbody and the joint structure are integrally cast and formed through an aluminum alloy. The rear wheel casing, the rear floor crossbeam and the rear longitudinal beam rear section are connected to thejoint structure. Due to the fact that the rear longitudinal beam front section body and the joint structure are integrally cast and formed through the aluminum alloy, the joint structure can be integrated on the rear longitudinal beam front section body, a rear floor crossbeam joint spliced by multiple steel parts such as a rear floor crossbeam upper joint and a rear floor crossbeam lower joint is prevented from being arranged on the rear floor crossbeam, the number of parts of the rear floor crossbeam is reduced, a splicing and welding structure on the rear floor crossbeam is simplified, sothat the weight of the rear floor crossbeam is reduced, and the strength and rigidity of the rear floor crossbeam are improved.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a rear floor frame structure of a vehicle body. Background technique [0002] At present, the rear floor frame structure of the existing automobile body is mainly composed of rear wheel housings, rear floor beams and rear floor longitudinal beams. The rear floor beams are usually provided with rear floor beam joints, and the rear floor beam joints The upper joint of the rear floor cross beam connected to the wheel house and the lower joint of the rear floor cross beam connected with the rear floor longitudinal beam are spliced ​​together to ensure the connection between the rear floor cross beam and the rear wheel housing and the rear floor longitudinal beam. However, since the rear floor beam joint needs to be spliced ​​by multiple steel parts such as the upper joint of the rear floor beam and the lower joint of the rear floor beam, the number of parts of the rear floo...
