Description

A kind of car body hinge column support structure

technical field

The utility model belongs to the technical field of automobile body parts, and more particularly relates to an automobile body hinge column support structure.

Background technique

At present, the standards and requirements of collision safety in the field of automobile safety are becoming more and more strict. The working conditions investigated in the more mainstream safety evaluation standards C-NCAP and Euro NCAP in the industry are mainly high-speed collisions of more than 50 kilometers. In the high-speed frontal collision condition, the effective transmission of the collision force is very important to the design of the vehicle frame structure. Therefore, it is required to fully consider the effective overlap between the load-bearing components in the structural design of the transmission path, and the reinforcement structure in the key section cavity should also be fully considered. However, with the decreasing energy resources, in order to reduce the consumption of power energy, the lightweight design of vehicles has become the main dimension in today's automobile design. The weight and cost increase brought by the complete and sufficient frame structure design should be considered simultaneously with the lightweight design. It is the trend of automobile design to seek the optimal structural design scheme, which can not only ensure the performance requirements but also control the weight of parts without increasing the cost. The current body frame structure has two forms for the design of the front impact force transmission path. One is that the inner reinforcement structure of the hinge column adopts a plate type reinforcement structure, and the reinforcement plate and the outer plate of the hinge column are connected by spot welding. In addition, the front baffle has no supporting structure connecting the root of the front longitudinal beam and the hinge column, and the collision force of the front longitudinal beam has no path to be transmitted to the hinge column, so as to be transmitted to the rear. Even if there is a transmission path of the front baffle diagonal brace, when the front collision force is transmitted to the inner panel of the hinge column through the diagonal brace, since there is no effective support structure in the section, the inner panel of the hinge column will be greatly deformed, resulting in the front baffle. The amount of plate intrusion cannot be effectively controlled; the other is that the hinge column section support structure of some models will be used in the hinge column cavity, which can well withstand the front collision force. However, most of them are combined welding structures of two or more parts. There are many stamping die costs and welding processes, and there is a large room for improvement in terms of weight and cost. Therefore, none of the structures in the prior art can effectively meet the vehicle performance requirements.
