Embodiment Construction

[0032] In the following embodiments, "outside" and "inside" in the design direction are relative to the direction of the impact force. When in use, the side of the impact-resistant structure facing the impact force, that is, the side directly bearing the impact force is The outer side, and vice versa for the inner side.

[0033] This embodiment provides an anti-shock structure 1, and the anti-shock structure 1 is made of carbon fiber material. The local schematic diagram of the impact-resistant structure 1 is as figure 1 shown. As a preferred embodiment, the impact-resistant structure 1 can be made of high-performance fiber-reinforced composite materials. A composite material made of this kind, thereby further improving the performance of the impact-resistant structure 1.

[0034] The porosity of the impact-resistant structure 1 gradually increases inward along the outer surface; in the inward direction along the outer surface, the gradient of the porosity-position distribu...

Abstract

The invention provides an anti-impact structure and anti-impact equipment. The porosity of the anti-impact structure is gradually increased inwards along the outer surface; in a direction inward along the outer surface, a gradient of a porosity-position distribution function at an intermediate location of the impact resistant structure is greater than a gradient of a porosity-position distribution function at start and end segment locations. According to the anti-impact structure, the outer layer has lower porosity and higher elastic modulus and can bear larger stress, the inner layer has higher porosity and can have larger deformation space and can bear larger strain, the buffering effect of the inner layer is facilitated, and the overall strength of anti-impact protection equipment is guaranteed.

Description

technical field [0001] The invention belongs to the field of anti-shock structures, in particular to an anti-shock structure and anti-shock equipment used in the design field of cushioning structures such as safety helmets, bulletproof vests, and sports shoe soles. Background technique [0002] In daily production and life and practical engineering applications, impact damage has caused huge losses to the safety of people's lives and properties. In aerospace, railway transportation, sports and other fields, the impact load acting on the body is an important factor of human injury. With the development of people's needs for daily life and engineering technology, the body has higher and higher requirements for the ability to withstand high loads. Therefore, the demand for high-strength, impact-resistant human body equipment is facing a trend of rapid growth. [0003] The impact-resistant structures in the prior art usually utilize the energy-absorbing properties of the equipm...
