Problems solved by technology

At present, the more common technology is to use steel stamping and forming parts to connect the overall mid-floor structure, which basically has a mid-floor longitudinal beam. The overall structure is more complicated, and there are many parts that constitute the mid-floor assembly. The difficulty increases; at the same time, in order to ensure the performance of the body and meet the safety requirements, its overall weight is always difficult to reduce, so the production cost is relatively high

Abstract

The invention discloses a longitudinal-beam-free middle floor assembly structure. The structure comprises a middle floor left side edge beam, a middle floor right side edge beam, a middle floor frontcross beam, a middle floor rear cross beam, a middle floor and a plurality of edge beam connecting plug-in pieces, and the middle floor comprises a middle floor front section plate, a middle floor middle section plate and a middle floor rear section plate. The front ends and the rear ends of the middle floor left side edge beam and the middle floor right side edge beam are connected with a plurality of edge beam connecting inserting pieces respectively, and the middle floor front cross beam and the middle floor rear cross beam are parallel to each other and connected between the middle floor left side edge beam and the middle floor right side edge beam. A mounting frame for mounting the middle floor front section plate, the middle floor middle section plate and the middle floor rear section plate is formed between the middle floor left side edge beam and the middle floor right side edge beam and between the middle floor front cross beam and the middle floor rear cross beam. The middlefloor assembly structure is light in overall weight, high in light weight advantage, good in side impact safety and high in practicability, and the bending and torsion resistance of the middle floor is effectively improved.

Description

technical field [0001] The invention relates to a mid-floor assembly structure without longitudinal beams, and relates to the technical field of assembly and connection of auto parts. Background technique [0002] The floor in the body is an important part of the body floor, which has high weight in terms of body performance, safety, light weight, and cost. At present, the more common technology is to use steel stamping and forming parts to connect the overall mid-floor structure, which basically has a mid-floor longitudinal beam. The overall structure is more complicated, and there are many parts that constitute the mid-floor assembly. The difficulty increases; at the same time, in order to ensure the performance of the body and meet the safety requirements, its overall weight is always difficult to reduce, so the production cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mid-floor as...
