Abstract

The invention provides a column A joint structure which comprises an engine hood assembly, a front vehicle body assembly, a fender assembly and a side wall assembly. The side wall assembly comprises aside wall outer board. The engine hood assembly, the fender assembly and the side wall outer board are fixed to the front vehicle body assembly. The fender assembly comprises a fender. The side wallouter board comprises a column A side wall outer board. A jointing gap between the fender and the column A side wall outer board is horizontally formed. The column A joint structure has the beneficialeffects that the jointing gap between the fender and the column A side wall outer board is horizontally formed, the shape of the fender is regular, the material use rate is high, the shape of the fender is unlikely to rebound, accuracy can be improved, and the machining forming difficulty is lowered.

Description

technical field [0001] The invention relates to an automobile body, in particular to an A-pillar joint structure. Background technique [0002] The lower joint of the A-pillar of the car body is an important joint structure of the car body, which plays an important role in determining the torsional stiffness of the car body and the safety of collisions. Under torsional conditions, frontal collisions and offset collisions of the car body, it is easy to cause car body cracks due to stress in this area. The A-pillar joints of the traditional joints are oblique joints, and its structure has the following problems: 1. The fender is limited by the upper end joints, resulting in low material utilization, and the upper end is prone to springback of parts, and the dimensional accuracy is poor; 2. The outer side wall The front end of the A-pillar is difficult to form and cracks easily, and the glue area of ​​the front windshield is severely wrinkled. Contents of the invention [00...
