The invention discloses a connecting structure, an automobile and a preparation method of the connecting structure. The connecting structure is used for connecting a longitudinal beam and a transversebeam of the automobile, the connecting structure comprises a connecting part and a supporting part, the connecting part comprises a connecting assembly, and the connecting assembly comprises a transverse beam connecting piece and a longitudinal beam connecting piece which are connected with each other; the transverse beam connecting piece is used for being connected with the transverse beam, andthe longitudinal beam connecting piece is used for being connected with the longitudinal beam; the supporting part comprises a side wall assembly and a flange assembly, the side wall assembly is formed by bending and extending from the transverse beam connecting piece to the direction close to a bottom plate of the automobile, and the flange assembly comprises a first flange and a second flange; the first flange is formed by bending and extending from the end, away from the transverse beam connecting piece, of the side wall assembly to the direction away from the transverse beam connecting piece, the second flange is formed by bending and extending from the end, close to the longitudinal beam connecting piece, of the side wall assembly to the direction away from the transverse beam connecting piece, and connecting corners of the first flange, the second flange and the side wall assembly are closed corners. The connecting structure is not prone to cracking in the stamping forming process or the automobile collision process.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a connection structure, an automobile and a preparation method of the connection structure. Background technique [0002] With the popularity of automobiles, people have higher and higher requirements for automobile safety, especially the collision strength and connection strength of automobiles. Among them, the connection structure of the automobile floor cross beam is to connect the car body longitudinal beam and the cross beam. However, the connection corner of the existing automobile floor cross beam connection structure is designed as an opening. In , cracking problems are prone to occur at the corners of the connection. [0003] In view of the above-mentioned defects, it is necessary to provide a new connecting structure, automobile and a method for preparing the connecting structure. Contents of the invention [0004] The main purpose of the present invention is to...
