Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] The structure of the front longitudinal beam of the present invention is shown in Figure 1 and Figure 2, and mainly includes four sections of structure: the first section 1a of the front longitudinal beam is the frontmost section of the front longitudinal beam, which is the area where the front longitudinal beam first deforms during a collision; The second section 1b of the longitudinal beam is a non-deformable area; the third section 1c of the front longitudinal beam is a variable strength area, which can be deformed during a collision; the fourth section 1d of the front longitudinal beam is a non-deformable area.

[0028] The front longitudinal beam structure is longitudinally arranged in the engine compartment of the automobile, the fro...

Abstract

The invention discloses a front longitudinal beam structure for automobiles, in particular discloses a novel front longitudinal beam structure adaptive to impacting energy absorption of automobiles. In the invention, the front longitudinal beam structure is divided into four segments as follows: the first segment is a front longitudinal beam foremost segment which is subjected to deformation firstly on the front longitudinal beam during impacting, a second segment is an indeformable segment, a third segment is a strength-variable segment and can be subjected to deformation during impacting, and the fourth segment is an indeformable segment in which a destructible filling material is filled. Compared with the traditional front longitudinal beam structure, by adopting the front longitudinal beam structure in the invention, the energy absorption capability of the front longitudinal beam can be improved, the automobile body invasion amount can be reduced, the acceleration of front impact of an automobile can be reduced, and the safety of the front impact of the automobile can be improved effectively.

Description

technical field [0001] The invention relates to an automobile front longitudinal beam structure which can effectively increase the collision energy absorption without increasing the automobile collision acceleration. Background technique [0002] The front side member is one of the main energy-absorbing parts of the front collision of the car, and its design has a great influence on the safety of the front collision of the car. For automobiles, due to the consideration of the chassis and the layout of the front engine, the front longitudinal beam is generally designed as an S-shape. In order to increase the impact energy absorption capacity of the front longitudinal beam, it is usually necessary to reasonably match the strength of each section of the front longitudinal beam, and to control the crushing sequence of the longitudinal beam and the deformation mode of the longitudinal beam, mainly through the structural dimensions of the longitudinal beam, stiffeners, and ribs. ...
