Abstract

A rear floor assembly structure of an automobile is provided, which is used for sol that problem that the rear floor assembly is prone to generate pits and the NVH performance of the rear floor when afunction piece is installed on the existing rear floor assembly, and improving the safety and comfort of the whole automobile. The present invention can be use for improving the NVH performance of the rear floor assembly of an automobile. The structure includes a rear floor body, and a rear sill disposed on the rear side of the rear floor body, middle beam and middle stiffening beam, the aft longitudinal beam, the cross section of the middle beam and the middle reinforced beam are several-shaped, The rear longitudinal beam is symmetrically arranged on both sides of the rear floor body in pairs, the two ends of the middle cross beam are respectively connected with the middle part of the rear longitudinal beam, the rear longitudinal beam and the middle cross beam are connected into an I-shape, and one end of the middle reinforcing beam is overlapped on the side of the middle cross beam.

Description

technical field [0001] The invention relates to the technical field of automobile body-in-white structure, in particular to an automobile rear floor assembly structure. Background technique [0002] The rear floor assembly is a part of the frame of the body-in-white and has the function of bearing. During assembly, when workers install some functional parts on the rear floor, if the design of a certain position of the floor is weak or the force transmission is not balanced, the floor is prone to pits, resulting in serious quality problems. Not only that, when the rear floor is subjected to excitation from the road surface and the engine, if the design is improper, it is easy to generate resonance, which will reduce the NVH performance of the vehicle, thus reducing the safety and comfort of the vehicle. Moreover, most of the existing floor assembly structures are weak, and reinforcement plates are pasted at relevant positions, which will lead to unbalanced force transmission...
