Abstract

The invention relates to an automobile longitudinal beam structure and a manufacturing method thereof, and belongs to the technical field of automobile longitudinal beams. The automobile longitudinalbeam structure comprises a longitudinal beam middle section body, an upper reinforcing plate of the longitudinal beam middle section and a lower reinforcing plate of the longitudinal beam middle section, wherein the sections of the longitudinal beam middle section body, the upper reinforcing plate of the longitudinal beam middle section and the lower reinforcing plate of the longitudinal beam middle section are of U-shaped structures; the inner wall of the longitudinal beam middle section body is fixedly connected to the outer wall of the lower reinforcing plate of the longitudinal beam middlesection in an attached mode; the inner wall of the lower reinforcing plate of the longitudinal beam middle section is fixedly connected to the outer wall of the upper reinforcing plate of the longitudinal beam middle section in an attached mode; a longitudinal beam middle section supporting plate is arranged in the upper reinforcing plate of the longitudinal beam middle section; the longitudinalbeam middle section supporting plate is of a U-shaped structure; fixing structures are arranged at the two ends of the longitudinal beam middle section supporting plate; and the fixing structures comprise a plurality of fixing plates perpendicular to each other. According to the designed automobile longitudinal beam structure, the anti-deformation capability is strong, the abnormal bending at a longitudinal beam avoiding wheel cap is avoided, the collision energy absorption is not influenced, and the living space of passengers in an automobile is further not reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile longitudinal beams, and more specifically relates to an automobile longitudinal beam structure and a manufacturing method thereof. Background technique [0002] The middle section of the longitudinal beam of the existing pure electric van logistics vehicle interferes with the tire envelope. Since the tire envelope cannot be changed, the section of the middle section of the longitudinal beam is partially avoided. The package is prone to abnormal bending, and the longitudinal beam crush mode is abnormal, which in turn affects the absorption of collision energy and affects the living space of the occupants in the vehicle. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] The purpose of the present invention is to solve the problem that the local strength of the middle section of the longitudinal beam of the existing pure electric van logistics ve...
