Embodiment 1

[0035] see figure 1 and figure 2 The energy-absorbing structure 10 provided in this embodiment includes a support body 11 and an energy-absorbing body 12, wherein the support body 11 is in the shape of a cube, and a first cavity 110 is formed inside the support body 11, and the energy-absorbing body 12 is accommodated in the second Inside a cavity 110 , and the energy absorbing body 12 abuts against the inner wall of the supporting body 11 .

[0036] When the energy-absorbing structure 10 is impacted, no matter which surface the impact force acts on the support body 11, the support body 11 can transmit the impact force to the energy-absorbing body 12, and then the energy-absorbing body 12 deforms through its own collapse. To absorb the impact energy generated by the impact force, so that the impact force gradually decreases until it disappears completely, thereby protecting the protected object to the maximum extent (the energy-absorbing structure 10 is installed on the prot...

Embodiment 2

[0041] see image 3 , the energy-absorbing structure provided by this embodiment is basically the same as that of Embodiment 1, the difference is that: the support body 11 includes six second frame bars 113, and each frame 111 is provided with only one second frame bar 113, each The two ends of the second frame bars 113 are respectively connected to the middle of the two first frame bars 112 distributed in parallel, the surface of the energy absorbing body 12 abuts against the six second frame bars 113, and the energy absorbing body 12 passes through the six second frame bars 113. Two frame bars 113 are used to receive impact energy.

Embodiment 3

[0043] see Figure 4 , the energy-absorbing structure provided by this embodiment is basically the same as that of Embodiment 2, the difference is that: the two ends of each second frame bar 113 are respectively connected to two opposite corners of the frame 111, that is, the second The frame bar 113 is located on the diagonal of the frame 111 .

Abstract

The invention belongs to the technical field of passive safety protection, and provides an energy absorption structure and an energy absorption buffer device. The energy absorption structure comprisesa support body and an energy absorption body, wherein the support body is in a cubic form; a first cavity is formed in the support body; the energy absorption body is contained in the first cavity and is propped against the inner wall of the support body; the energy absorption buffer device comprises a plurality of energy absorption structures, and every two adjacent support bodies are fixedly connected. According to the energy absorption structure and the energy absorption buffer device provided by the invention, the cubic support bodies are adopted to be matched with the energy absorption bodies separately, the same energy absorption buffer effect can be achieved due to the fact that impact force transmitted to each energy absorption body through any surface of the corresponding supportbody is the same, the energy absorption buffer requirements of a protected object can be met only by splicing a plurality of energy absorption structures into the energy absorption buffer device under different use scenarios, and the structures of the energy absorption structures do not need to be changed, therefore, the technical problems that the energy absorption structures need to be independently designed according to specific scenarios, and the universality is not high are effectively solved.

Description

technical field [0001] This application belongs to the technical field of passive safety protection, and more specifically relates to an energy-absorbing structure and an energy-absorbing buffer device. Background technique [0002] Energy-absorbing structures are widely used in passive safety protection fields such as passive safety, impact collision, anti-riot and explosion-proof. The energy-absorbing structures commonly used today need to be designed individually according to the specific scenarios required, which are not very versatile, and have the disadvantages of long design and production cycles and high costs. Contents of the invention [0003] The purpose of this application is to provide an energy-absorbing structure and an energy-absorbing buffer device, including but not limited to solving the technical problem that the energy-absorbing structure needs to be designed individually according to specific scenarios and is not universal. [0004] In order to solve...
