AI Technical Summary

Technical Problem

The production process of traditional rear floor skeletons is complex and the number of parts and welding points is large, resulting in low production efficiency and high cost, which violates the cost reduction and efficiency improvement needs of automobile manufacturers.

Method used

A rear floor skeleton assembly with a high degree of integration was designed. By reducing the number of welding joints and welds and reducing the number of molds or inspection tools, an efficient welding process and structural design were adopted. For example, the first weld and the third weld were in the same line, and the second weld and the fourth weld were in the same line, simplifying the welding process.

Benefits of technology

It has achieved shortening production lines, reducing stations and site demands, improving factory utilization, reducing production costs and improving production efficiency.
