Embodiment Construction

[0022] With reference to the accompanying drawings, the specific embodiments of the present invention, such as the shape and structure of each component involved, the mutual position and connection relationship between each part, the function and working principle of each part, etc. detailed description.

[0023] like Figure 1-3 , the automobile rear floor assembly structure of the present invention includes a rear floor body 1, and also includes a rear longitudinal beam 2, a middle cross beam 3 and a middle reinforcing beam 4 arranged on the back of the rear floor body 1, the rear longitudinal beam 2, the middle beam 3 and the middle reinforcement beam 4. The cross-sections of the middle reinforcing beams 4 are all in the shape of a "ji". The rear longitudinal beams 2 are arranged in pairs and symmetrically on both sides of the rear floor body 1. 2 and the middle beam 3 are connected to form an "I" shape, and one end of the middle reinforcing beam 3 is overlapped on the sid...

Abstract

The invention provides an automobile rear floor assembly structure, which is used to solve the problem of pits on the rear floor and the NVH performance of the rear floor easily caused by the installation of functional parts in the existing rear floor assembly, so as to improve the safety and comfort of the whole vehicle . The structure includes a rear floor body, and also includes a rear longitudinal beam, a middle beam and a middle reinforcement beam arranged on the back of the rear floor body. The rear longitudinal beams are arranged in pairs and symmetrically on both sides of the rear floor body, the two ends of the intermediate beams are respectively connected to the middle of the rear longitudinal beams, and the rear longitudinal beams and the intermediate beams are connected to form an "I" shape , one end of the middle reinforcement beam is lapped on the side of the middle beam.

Description

technical field [0001] The invention relates to the technical field of automobile body-in-white structures, in particular to an automobile rear floor assembly structure. Background technique [0002] The rear floor assembly is a part of the body-in-white framework and has a bearing role. During assembly, when workers install some functional parts on the rear floor, if the design of a certain position on 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 the excitation from the road surface and the engine, if the design is improper, resonance will easily occur, 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 attach reinforcing plates at relevant positions where they are weak, which will lead to an unbalanced force transmission design a...
