Problems solved by technology

[0002] For most automobile bodies, the rear longitudinal beam has always been a key load-bearing part that is difficult to mold in sheet metal parts. Due to the large beam body and complex shape, the cost of the mold is high, and the quality of the sheet metal parts is consistent. Difficult to control, sheet metal parts are easily distorted and deformed
[0003] The original structure is an integral longitudinal beam structure, the beam body is large, and the longitudinal beam profile is complex, resulting in high mold costs. At the same time, due to the large single piece, it is easy to twist and deform, and the complex profile is difficult to adjust.

Abstract

The invention discloses a structure of a multi-section rear longitudinal beam. The structure comprises a first front section of a rear longitudinal beam, a middle sectionof the rear longitudinal beam,a second front section of the rear longitudinal beam, a first welding point and a second welding point, wherein one end of the middle section of the rear longitudinal beam is arranged at one end of the first front section of the rear longitudinal beam; the other end of the middle section of the rear longitudinal beam is arranged at one end of the second front section of the rear longitudinal beam; the first front section of the rear longitudinal beam is connected with one end of the middle section of the rear longitudinal beam through the first welding point; the other end of the middle section of the rear longitudinal beam is connected with one end of the second front section of the rear longitudinal beam through the second welding point; a first front section overlapping end is arrangedoutside one end of the first front section of the rear longitudinal beam; a first front section outer chamfer is arranged outside the first front section overlapping end; and a first front section inner chamfer is arranged inside the first front section of the rear longitudinal beam. The structure is divided into a three-section longitudinal beam, so that the mold opening cost is less; and meanwhile, each section of the beam is small, so that the molding is relatively easy, and the quality of each section of the beam is well controlled.
