Embodiment 1

[0034] An energy absorption module based on porous metal foam, hereinafter referred to as the energy absorption module, such as figure 1 and figure 2 As shown, the energy absorption module is composed of multiple energy absorption units, such as figure 1 as well as Figure 3-Figure 10 Shown is a schematic diagram of the structure of a single energy-absorbing unit. The energy-absorbing unit includes a lock head assembly, a keyhole assembly, a mounting plate 1, a clamping plate 2, an anti-collision plate 3, a foam metal block 4, a deformation beam 5, and a wave plate 6. , the main pull rope 7 and the side pull rope 8; the upper side and the lower side of the mounting plate 1 are respectively welded with several clamping plates 2; structure; the front ends of all the card boards 2 are respectively connected with the same bumper plate 3 through the first buckle 21 structure; a foam metal block 4 is placed between the bumper plate 3 and the mounting plate 1; The rear side is mo...

Embodiment 2

[0047] like Figure 4 As shown, this embodiment is further optimized on the basis of Embodiment 1. Two through-slots 35 are formed inside the plate main body 31 of the crash plate 3 .

[0048] When a certain independent collision zone of the collision board 3 is slightly impacted, the through groove 35 in the plate main body 31 of the collision board 3 is impacted by the impact and collapses backward to produce deformation, and the impact of the collision board 3 is affected. The impact force of slight impact is absorbed to provide the energy-absorbing unit with a light energy-absorbing effect, preventing the energy-absorbing unit from triggering the entire energy-absorbing mechanism due to slight impact, resulting in the entire energy-absorbing unit needing to be replaced, further enabling the maintenance cost to be effectively controlled.

Abstract

The invention relates to the field of foam metal energy absorption, in particular to an energy absorption module based on porous foam metal. In order to solve the technical problems that the foam metal needs to have enough thickness to provide efficient shock-filtering and energy-absorbing effects and the whole anti-collision and energy-absorbing module is scrapped if one area is impacted and damaged, the energy-absorbing module based on the porous foam metal comprises a plurality of energy-absorbing units, the adjacent energy absorption units are locked together through the lock head assemblies and the lock hole assemblies, deformation beams, waved plates, main pull ropes and foam metal blocks are further arranged in the energy absorption units and used for transversely absorbing impact force generated in the impact process, and the upper sides and the lower sides of the energy absorption units are each provided with a side pull rope through a clamping plate. The two ends of the side pull rope are connected with a lock head assembly and a lock hole assembly which are arranged on the left side and the right side of the energy absorption unit correspondingly, and when the anti-collision plate is violently impacted to enable the clamping plate to be bent and deformed, the side pull rope can pull the lock head assembly to be separated from the lock hole assembly.

Description

technical field [0001] The invention relates to the field of foam metal energy absorption, in particular to an energy absorption module based on porous metal foam. Background technique [0002] Porous metal foam refers to a special metal material containing foam pores. Due to its porosity as high as 90%, it has low density, good heat and sound insulation performance, and can absorb electromagnetic waves. It is often used in aerospace, transportation and construction chemicals. and other fields, patent CN213199066U discloses a composite rubber damping pad with noise reduction function, which mounts foam metal in various materials to improve the heat absorption, sound insulation and shock filtering effects of the entire composite material. [0003] However, when the composite material equipped with foam metal is applied to the anti-collision energy-absorbing module, since the foam metal absorbs the impact force longitudinally, the foam metal needs to have a sufficient thicknes...
