Abstract
The invention discloses a connecting structure, a car and a method for preparing the connecting structure. The connecting structure is used to connect longitudinal beams and beams of the car. The connecting structure includes a connecting part and a supporting part. The connecting part includes a connecting component, and the connecting component includes cross beams connected to each other. The connecting piece and the longitudinal beam connecting piece, the crossbeam connecting piece is used for connecting with the crossbeam, the longitudinal beam connecting piece is used for connecting with the longitudinal beam, the supporting part includes a side wall assembly and a flange assembly, and the side wall assembly extends from the crossbeam connecting piece to the side close to the car The bottom plate is formed by bending and extending in the direction of the bottom plate. The flange assembly includes a first flange and a second flange. The flange is formed by bending and extending from an end of the side wall component close to the longitudinal beam connector to a direction away from the cross beam connector, and the connection corners of the first flange, the second flange and the side wall component are closed corners. The connection structure of the present invention is not easy to crack when it is stamped and formed or when a car collides.
Description
Connection structure, automobile and preparation method of connection structure technical field [0001] The present invention relates to the technical field of automobiles, in particular to a connection structure, an automobile and a method for preparing the connection structure. Background technique With the popularization of automobiles, people's requirements for automobile safety are getting higher and higher, especially the collision strength and connection of automobiles. connection strength. Among them, the connection structure of the car floor beam is to connect the body longitudinal beam and the beam, however, the existing car floor The connecting corner of the connecting structure of the beam is designed as an opening, which is stamped into the strength crash test of the automobile body and the connecting structure parts. During the forming process, cracks are prone to occur at the corners of the connection. [0003] In view of the above-mentioned defects, it ...
