Embodiment

[0017] Example: such as figure 1 , figure 2 As shown, an automobile crash box structure includes a crash box body 3 composed of overlapping U-shaped crash box outer panels 1 and U-shaped crash box inner panels 2, and the front end of the crash box body 3 is fixedly arranged There is a front end plate 4, and a rear end plate 5 is fixedly arranged at the rear end of the energy absorbing box body 3; a group of energy absorbing plates are arranged symmetrically on the overlapping surfaces of the U-shaped energy-absorbing box outer plate 1 and the U-shaped energy-absorbing box inner plate 2 Rib 6; the crash box body 3 is a conical structure with a cross-sectional area increasing along the direction from the front to the rear of the vehicle. The arrangement position of the energy-absorbing ribs 6 overlaps with the waveform of the crush wave; the width of the energy-absorbing ribs 6 is equal to the half-wavelength of the crush wave. The group of energy-absorbing ribs 6 includes a ...

Abstract

The invention relates to an automobile energy absorption box structure. The automobile energy absorption box structure comprises an energy absorption box body (3) which is formed by a U-type energy absorption box outer board (1) and a U-type energy absorption box inner board (2) in a mutually lapped mode, a front end board (4) is fixedly arranged at the front end of the energy absorption box body (3), a rear end board (5) is fixedly arranged at the rear end of the energy absorption box body (3), a set of energy absorption bars (6) is symmetrically arranged on two lapped faces of the U-type energy absorption box outer board (1) and the U-type energy absorption box inner board (2), the energy absorption box body (3) is of a tapered structure, and the area of the cross section of the tapered structure is gradually increased in the direction from an automobile head to an automobile tail. The arrangement positions of the energy absorption bars (6) are overlapped with the wave shapes of crushing waves. The width of the energy absorption bars (6) is equal to the half wavelength of the crushing waves. The automobile energy absorption box structure is simple in structure and reasonable in design, can carry out collapse and energy absorption to the largest limitation, and can be widely applied to the field of automobile crashes.

Description

technical field [0001] The invention relates to an automobile collision energy-absorbing structure, in particular to an automobile energy-absorbing box structure. Background technique [0002] Because low-speed collisions require body parts to be repairable after collisions, large deformations of the front longitudinal beams are not allowed. That is to say, only the anti-collision beam and the energy-absorbing box are allowed to deform, which requires the load-resistant capacity of the energy-absorbing box to be lower than that of the front longitudinal beam. For each model, due to the inconsistency in the cross-sectional size of the front longitudinal beam, the selection of materials, and the quality of the body, the load-bearing capacity of the longitudinal beam is different. It is necessary to design the energy-absorbing box based on the CAE analysis of the load-resistant capacity of the longitudinal beam of the vehicle. And it absorbs more energy during high-speed colli...
