Abstract

The invention discloses an automobile with special steel-aluminum section connecting pieces, especially connecting pieces for a frame and a body. The connecting pieces disclosed by the invention are aluminum sections, certain ends of the connecting pieces are connected with an aluminum section frame structure through welding, and the other ends of the connecting pieces are fixedly connected with a steel section body through bolts. The automobile with the special steel-aluminum section connecting pieces has the beneficial effects that the process principle is universal, the connecting pieces can be applied to connection of materials of different kinds and the application scope is wide; since an open design is adopted, on the premise that product manufacturing is not influenced, the shapes of the connecting pieces can be optimized; the connecting method is simple, the strength is high and the cost is low.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a connection structure of a skeleton structure of a new energy automobile. Background technique [0002] With the development of industry and the advancement of science and technology, in order to meet the needs of high strength, light weight and corrosion resistance of product structures, the connection of aluminum and steel dissimilar materials has been widely used in automobile manufacturing, mechanical parts, building structural materials, aerospace, etc. in the field. This process is especially used in new energy electric vehicle technology. In general, the skeleton structure of new energy electric vehicles is mainly composed of steel profiles and steel sheet metal parts, such as figure 1 As shown, the side beams of the top cover and the lower beam of the windshield are made of aluminum profiles, and other structures are made of steel profiles. [0003] However, the c...
