Description

Technical Field

[0001] This invention relates to the field of buffer energy absorption device technology, and in particular to a buffer energy absorption device based on origami structure. Background Technology

[0002] With the development of the times, the application of buffer energy absorption devices is becoming increasingly widespread, not only in high-precision fields such as military and aerospace, but also in everyday life. For example, they are used in cargo transportation, structural protection, and various household items. Traditional common buffer energy absorption devices include spring-type buffer energy absorption devices and hydraulic buffer energy absorption devices, etc. However, traditional buffer energy absorption devices have drawbacks such as being too lightweight, having low specific energy absorption, being cumbersome to install, and having limitations in manufacturing methods and available materials. Therefore, there is a need to develop more high-performance buffer energy absorption devices. Although lighter buffer energy absorption devices with honeycomb structures as the core and increased specific energy absorption have emerged, and traditional hexagonal honeycomb structures have good out-of-plane compressive performance, they have a high initial peak stress upon impact. High peak stress leads to enhanced force transmission and reduces energy absorption effect. Furthermore, the mechanical properties of honeycomb-based buffer energy absorption devices are also highly affected by impact velocity (Zhang, M. Ashby, The out-of-plane properties of...). Honeycombs, Int. J. Mech. Sci. 34 (1992) 475–489.), therefore, the performance of energy-absorbing buffer devices based on traditional honeycombs still needs to be improved. In order to obtain a buffer energy-absorbing device with better performance, this invention uses origami structure as the core and invented a buffer energy-absorbing device. In recent years, origami structure has attracted widespread attention from many researchers. Many origami structures have shown good high energy absorption characteristics and no obvious initial peak force during axial strain (Tomita S, Shimanuki K, Nishigaki H, et al. Origami-inspired metamaterials with switchable energy absorption based on bifurcatedmotions of a Tachi-Miura polyhedron[J]. Materials & Design, 2023, 225). Many origami structures also have negative Poisson ratio characteristics. The negative Poisson ratio characteristic will make the elastic modulus of the structure increase with the increase of axial compression displacement.Moreover, the geometric configuration of origami metamaterials is closely related to their overall mechanical properties (Zhang P, He Y, Yang H, et al. The Mechanical Behavior of Polyline Crease Origami Self-Locking Structure under Quasi-Static Compressive Loading[J]. Mathematical Problems in Engineering, 2022, 2022: 1-16). Different usage requirements can be met by changing the geometric parameters of the units. In addition, origami structures have rich reconfigurability and can be combined into different wholes according to certain rules (Yamaguchi K, Yasuda H, Tsujikawa K, et al. Graph-theoretic estimation of reconfigurability in origami-based metamaterials[J]. Materials & Design, 2022, 213). Therefore, it is necessary to invent a buffer energy absorption device based on origami structures to meet the needs of society. Summary of the Invention

[0050] The present invention has the following beneficial effects:

[0051] (1) The core of this invention is the introduction of an origami structure. The geometric configuration of the origami structure is closely related to the overall mechanical properties. Therefore, the energy-absorbing buffer device can obtain different mechanical properties by changing the geometric parameters, and has a degree of design freedom that traditional energy-absorbing buffer devices do not have. Furthermore, the folded energy-absorbing buffer functional module group formed by this origami structure allows the device to obtain a lower initial peak stress and a relatively stable and reasonable motion trajectory when impacted.

[0052] (2) The present invention is lightweight, has high specific energy absorption, and is easy to install. It can be put into use without complicated installation procedures, and will not have a negative impact on use due to excessive weight.

[0053] (3) This invention has a wide range of applications. Because it is simple in structure and easy to install, it can be used in multiple fields and multiple scenarios. Whether it is a low-speed or high-speed application scenario, for example, from the protection of highway toll stations to the design of shoe midsole structure, this invention can be used to achieve the purpose of buffering and energy absorption.

[0054] (4) The present invention also features multiple manufacturing methods. For example, the folding method can be used to complete the folding buffer energy absorption functional module group. This method is low in cost and simple to operate. The folding buffer energy absorption functional module group can also be manufactured by 3D printing, which allows us to easily make various folding buffer energy absorption functional module groups with different geometric parameters. The entire device, including the buffer plate and the folding buffer energy absorption functional module group, can be manufactured in one piece by 3D printing and mold casting. As long as it does not affect the use, the manufacturing method is not limited. The multiple manufacturing methods can better meet the needs of society.

[0055] (5) The present invention also has the advantage of a wide range of materials that can be used. The present invention can be made of a variety of materials, and different materials can provide different mechanical properties. The wide range of materials that can be used also makes the manufacturing of this device more convenient.

[0056] (6) The present invention can also provide a good kinetic energy rebound rate by adjusting geometric parameters and selecting appropriate materials, which makes it have great application potential in the sports goods market.

[0057] Application examples:

[0058] (1) The invention is installed on the outer wall of the toll booth of a highway toll station. The bottom buffer plate is fixed with bolts and the top buffer plate faces the direction where the vehicle may lose control and rush towards it. At this time, the invention is applied to the scenario where a large mass vehicle may impact at high speed. Therefore, when selecting the materials for the bottom buffer plate, the top buffer plate and the folding buffer energy absorption functional module group, materials with sufficient strength must be selected. The huge kinetic energy generated by the high-speed impact of the vehicle is offset by plastic deformation, thereby achieving the effect of buffering and absorbing energy and protecting people's lives and property.

[0059] (2) This invention can be applied to the transportation industry and to the transportation of fragile items. Traditional express delivery uses non-environmentally friendly materials such as plastic to protect fragile items. This buffer energy-absorbing device can be made by using materials such as cardboard and folding method. It can not only buffer and absorb energy to protect fragile items, but also be reused to help protect the environment.

[0060] (3) Applying the present invention to the midsole structure of shoes, the present invention introduces a paper-folding structure. The geometric configuration of the paper-folding structure is closely related to the overall mechanical properties. When this device is used in the midsole structure of shoes, it can not only play the role of cushioning and absorbing energy, but also obtain multiple mechanical properties by changing the geometric parameters, number of layers, and combination arrangement of the paper-folding structure units. However, when selecting the materials for the bottom cushioning plate, top cushioning plate, and folding cushioning and absorbing energy functional module group in this application scenario, the rebound performance of the materials must be considered.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
