Problems solved by technology

[0006] Steel plate stamping parts overlap each other, the structure is complex, and the strength and rigidity of a single piece are low, while the profile has good strength and high rigidity, especially for the high torsional and bending alternating loads at the front end of the cabin
[0007] Mass production cost problem: the cost of stamping dies for steel plates is relatively high, basically ranging from 500,000 to 1 million
[0008] The problem of connection effectiveness: using welding as a connection method, there is a large heat-affected zone in welding, and the material performance in the heat-affected zone is reduced by 30-40%, and there is uncertainty and large deformation in the direction of deformation of the parts caused by welding, which will Reduced bodywork precision
Riveting has the disadvantages of low shear strength and low peel strength

Abstract

The invention relates to the technical field of automobiles, in particular to an automobile body aluminum profile water tank column and an automobile. The automobile body aluminum profile water tank column comprises a main board, a first connecting frame and a second connecting frame. The first connecting frame and the second connecting frame are fixedly arranged on the same side of the main board; The first connecting frame comprises a first support plate and a second support plate; The first support plate and the second support plate together form a triangular cavity structure with the mainplate; The second connecting frame comprises a third support plate and a fourth support plate; The third support plate and the fourth support plate together with the main plate form a triangular cavity structure. The automobile body aluminum profile water tank column and the automobile provided by the invention are provided with two connecting frames arranged on the main board, so that one part isreliably connected with the other part at the same time by two identical side faces, and the cross-section structure enables the product to have higher strength, rigidity, bending and torsion resistance; Using aluminum alloy profile longitudinal / transverse beam, it has high strength and strength, and the investment of mould is low, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a water tank column made of aluminum profiles for automobile bodies and an automobile. Background technique [0002] As the all-aluminum body technology becomes more and more popular, there is no profile-type water tank column applied to automobiles in the market, and they are basically steel plate stamped columns. Therefore, the body radiator column structure and connection technology of aluminum alloy profiles have not yet been involved. [0003] The stamped parts of the steel plate are overlapped with each other, the main parts are all stamped and formed, and the connection between the longitudinal beam and the column is welded or riveted through the flange of the parts. [0004] Parts are mainly joined by riveting or welding. Aluminum stamping parts have disadvantages such as complex structure, long design cycle, and mold cost (at least 5 million or more). There is a l...
