Abstract

The invention provides a front longitudinal beam rear portion reinforcing structure. The front longitudinal beam rear portion reinforcing structure comprises a first beam (1) and a pair of second beams (2), wherein the first beam (1) is connected between root portions (40) of left and right front longitudinal beams (4), and the second beams (2) are connected between the root portions (40) of the front longitudinal beams (4) and a column A (5) on the same side. According to the front longitudinal beam rear portion reinforcing structure, the first beam is arranged between the root portions of the left and right front longitudinal beams so that the first beam is located in an impact force delivery area, an impact force can be effectively resisted and dispersed, and intrusion of a dash board is reduced.

Description

technical field [0001] The invention relates to the field of automobile body structures, in particular to a front longitudinal beam rear reinforcement structure and a manufacturing method thereof. Background technique [0002] During a frontal collision of a car, the front side member is the most important energy-absorbing component. How to resist and disperse the collision force and reduce the intrusion of the dash panel is the focus of the research on the front longitudinal beam structure. In the prior art, a cross beam is arranged above the rear part of the front longitudinal beam, and the two ends are respectively connected with the A-pillar, so as to resist the collision force. However, under this arrangement, the beam cannot effectively transmit the impact force to reduce the intrusion of the dash panel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rear reinforcement structure of the front longitudin...
