Abstract

The invention discloses a front longitudinal beam structure which comprises a longitudinal beam body. The longitudinal beam body is composed of a longitudinal beam front section, a longitudinal beam middle section and a longitudinal beam rear section, wherein the longitudinal beam front section is connected with a front bumper bar, the longitudinal beam middle section is composed of a first strut beam and a second strut beam, wherein the first strut beam and the second strut beam protrude outwards from the middle portions, two ends of the first strut beam are connected with the longitudinal beam front section, and two ends of the second strut beam are connected with the longitudinal beam rear section. According to the front longitudinal beam structure, intensity of the front longitudinal beam structure middle section in the transverse direction is larger than that of in the vertical direction, bending of the longitudinal beam middle section can be conducted in the longitudinal vertical plane, and bending mold can be controlled in advance according to arrangement of the structure of the front longitudinal beam structure. Stability of bending is ensured by longitudinal beams when the longitudinal beams conduct bending energy absorption, the front longitudinal beam structure can reach an expected transformation model and has sufficient energy absorption characteristics, and therefore safety protection is provided for a driver.

Description

technical field [0001] The invention relates to the technical field of car body structure design for safety protection, in particular to a front longitudinal beam structure. Background technique [0002] As the relevant safety regulations become more and more stringent, higher requirements are put forward for the body structure in terms of automobile design. In the event of an internal collision, the front longitudinal beam can fully absorb the collision energy and provide safety protection for the driver. Therefore, in practical application, the longitudinal beam must achieve the expected deformation mode and have sufficient energy absorption capacity. However, in fact, the deformation mode and energy absorption characteristics of the longitudinal beam are difficult to control, and sometimes deviate from the original intention of the designer, not only failing to achieve the expected effect, but also causing potential safety hazards. Contents of the invention [0003] Th...
