Description

Technical Field

[0001] The present invention relates to the technical field of puncture-resistant armor plate unit structures, and in particular to a bionic phosphorus armor-type stress-dispersing modular component with three-dimensional freedom of movement. Background Art

[0002] To protect themselves from the environment and predators, organisms in nature have evolved a variety of biological armor over time. From the hard shells of mollusks to the thick, helmet-like skulls of dinosaurs, armor structures must not only provide mechanical protection but also serve multiple functions, such as hydrodynamic drag reduction, coloration, and optical, chemical, and mechanical sensing. However, the rigidity and hardness of most biological armor limits its flexibility. Therefore, maintaining both protective performance and flexibility has become the convergent evolutionary direction of various organisms with scaly armor. Nature's solution is to replace larger scaly armor units with small, repeating units, as seen in fish, turtles, armadillos, crocodiles, and pangolins.

[0003] Scale-based biological armor can be divided into two categories: overlapping scales (e.g., pangolins, some fish, and snakes) and adjacent bony plates, also known as osteoderms (e.g., turtles, lizards, alligators, and armadillos). The former, particularly fish scales, achieve both protection and flexibility through the relative rotation, sliding, and bending of scale units. Unlike fish scales, osteoderm-based armor derives its flexibility from the relative movement of adjacent plates, either through the elastic Sharp's fibers that connect them (e.g., armadillo scales) or through interdigital sutures (e.g., turtle scales).

[0004] Throughout human history, there are many examples of the desire to combine protection and flexibility through structural design, from the cumbersome medieval armor to the flexible and lightweight structure of traditional Chinese chain mail, and even to the modern development of biomimetic flexible protective structures. However, most previous research on biomimetic flexible scale armor has focused on simplifying the shape elements of scales, combining them with puncture-resistant materials to form armor structures with primarily two-dimensional design elements, such as flat surfaces, or combining them with soft substrates to create protective fabrics with primarily woven structures.

[0005] Although the existing technology has achieved certain research and application results in the simplified imitation of biological scale shape elements, there is still ample room for improvement. On the one hand, the overly complex scale structure will cause a significant increase in preparation costs. On the other hand, the biological scale unit structure that people refer to may not achieve the optimal solution in terms of puncture resistance and stress dispersion due to other biological reasons or functions (such as heat dissipation).

[0006] At present, parametric modeling and 3D printing have become powerful means to study the mechanical behavior of biological and bionic materials and structures, and have become an effective and low-cost process for solving complex nail plate structures. Therefore, if there is a bionic nail plate unit with structural optimization based on biological scales, it will provide a new foundation and development space for current protective materials. Summary of the Invention

[0007] In light of the aforementioned shortcomings of the prior art, the present invention aims to provide a bionic phosphorus armor-like stress-dispersing modular component with three-dimensional freedom of movement. The modular component, constructed through interlocking chains, can reversibly switch between soft and hard states, providing adjustable mechanical properties. Furthermore, the combination of bionic armor plates and modular scale armor structures not only achieves a rigid-flexible transition, but also further dissipates stress through the overlapping structure of the bionic armor plates, improving impact resistance.

[0008] To achieve the above objectives, the present invention is implemented by adopting a technical solution consisting of the following technical measures.

[0009] In one aspect, the present invention provides a bionic nail plate with high puncture resistance, wherein the shape of the bionic nail plate is mainly a geometric body composed of a rhombus bottom surface, a symmetrical hyperbolic outer surface, and a symmetrical hyperbolic inner surface;

[0010] On an axial section of the geometric body perpendicular to the rhombus base and passing through the short diagonal of the rhombus base, the contour line of the axial section is composed of the short diagonal, the outer armor curve, and the inner armor curve. A rectangular coordinate system is constructed for the contour line of the axial section with the intersection point of the inner armor curve and the short diagonal as the coordinate origin (0, 0). The coordinates of the intersection point of the outer armor curve and the short diagonal are (16, 0). The x value of the coordinate point of the intersection point of the outer armor curve and the inner armor curve is -6.5 to -7.1, and the y value is 7.5 to 8.35. When the x value of the outer armor curve is 0, the y value is 10. The outer armor curve and the inner armor curve are both parabolas that satisfy the above coordinate relationship.

[0011] On the inner and outer dividing sections of the geometric body determined by the intersection of the outer armor curve and the inner armor curve and the long diagonal of the rhombus base, the contour lines of the inner and outer dividing sections are composed of the long diagonal and the inner and outer dividing curves. A rectangular coordinate system is constructed for the contour lines of the inner and outer dividing sections with the center point of the long diagonal as the coordinate origin (0, 0), and the coordinates of the endpoints of the long diagonal are (-16, 0) and (16, 0) respectively; when the x value of the inner and outer dividing curves is 0, the y value is 17 to 17.5, and the inner and outer dividing curves are parabolas that satisfy the above coordinate relationship;

[0012] The outer carapace surface is composed of two symmetrical curved surfaces A, and the edge of the curved surface A is composed of inner and outer dividing curves, the outer carapace curve, and the edge of the rhombus bottom surface adjacent to the outer carapace curve;

[0013] The inner nail surface is composed of two symmetrical curved surfaces B, and the edge of the curved surface B is composed of inner and outer dividing curves, the inner nail curve and the edge of the rhombus bottom surface adjacent to the inner nail curve.

[0014] In this article, the diamond bottom surface and the outer nail surface can also be understood as symmetrical biconcave surfaces extending from the double edges on one side of the diamond bottom surface, thereby constituting the outer nail surface of the symmetrical biconcave surface shape; the diamond bottom surface and the inner nail surface can also be understood as symmetrical biconcave surfaces extending from the double edges on the other side of the diamond bottom surface, thereby constituting the inner nail surface of the symmetrical biconcave surface shape.

[0015] In this article, the edge of the surface A is composed of the inner and outer dividing curves, the outer carapace curve and the edges of the diamond bottom surface adjacent to the outer carapace curve. The surface shape / parameters of the surface A are formed based on the closed contour line formed by the inner and outer dividing curves, the outer carapace curve and the edges of the diamond bottom surface adjacent to the outer carapace curve, and its smooth surface structure design is realized based on the modeling function of the three-dimensional modeling software.

[0016] In one of the technical solutions, based on the simulation results, in order to ensure high puncture resistance while reducing the weight of the bionic nail plate as much as possible, the curved surface A is a concave surface, and its specific shape is as follows: Figure 7 As shown, or the specific shape of surface A is as follows Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 Any one or more of the figures shown.

[0017] In this article, the edge of the surface B is composed of the inner and outer dividing curves, the inner armor curve and the edges of the diamond bottom surface adjacent to the inner armor curve. The surface shape / parameters of the surface B are formed based on the closed contour line formed by the inner and outer dividing curves, the inner armor curve and the edges of the diamond bottom surface adjacent to the inner armor curve, and its smooth surface structure design is realized based on the modeling function of the three-dimensional modeling software.

[0018] In one of the technical solutions, based on the simulation results, in order to ensure high puncture resistance while reducing the weight of the bionic nail plate as much as possible, the curved surface B is a concave surface, and its specific shape is as follows: Figure 7 As shown, or the specific shape of surface A is as follows Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 Any one or more of the figures shown.

[0019] In one of the technical solutions, based on the simulation experimental results, in order to improve the puncture resistance of the bionic nail plate, in a rectangular coordinate system constructed with the intersection of the inner nail curve and the short diagonal line as the coordinate origin (0, 0), the curve formula of the outer nail curve is y=-(5 / 128)x 2 +10; the curve formula of the inner nail curve is y=-0.1673x 2 -2.2257x.

[0020] In one of the technical solutions, based on the simulation experimental results, in order to improve the puncture resistance of the bionic nail plate, in a rectangular coordinate system constructed with the center point of the long diagonal as the coordinate origin (0, 0), the curve formula of the inner and outer segmentation curve is y=-(17.25 / 256)x 2 +17.25.

[0021] In one technical solution, the intersection of the diamond-shaped bottom surface, the inner nail surface, and the outer nail surface on the geometric body is a rounded edge. In actual modeling, the rounded edge can be achieved by using functions such as filleting / cutting corners / cutting edges based on 3D modeling software.

[0022] In one technical solution, the outer armor curve, the inner armor curve, and the inner and outer dividing curves on the geometric body are rounded edges. In actual modeling, the rounded edges can be achieved by using functions such as filleting / cutting / cutting edges based on 3D modeling software.

[0023] On the other hand, based on the above-mentioned bionic nail plate with high puncture resistance, the present invention provides a bionic phosphorus armor-style stress dispersion modular component with three-dimensional freedom of movement, which mainly includes the above-mentioned bionic nail plate with high puncture resistance and a combined base module. The combined base module is mainly composed of a nail plate base member and a movable connecting member.

[0024] The nail base is a quadrangular pyramid-shaped frame structure, comprising a prismatic base for fixed connection to the prismatic bottom surface of the bionic nail. When the rhombus-shaped base serves as the lower bottom surface of the quadrangular pyramid, the upper bottom surface corresponding to the lower bottom surface is formed by a single top prism, and side prisms fixedly connected to the center point and two end caps of the top prism are respectively connected to the four corners of the prismatic base; the angle between the side prisms adjacent to the long diagonal line of the prismatic base and the prismatic base is 30 to 60 degrees;

[0025] The movable connecting piece is a frame structure in the shape of a quadrangular pyramid. The side prisms on the nail base piece pass through the bottom surface and side surfaces of the movable connecting piece, so that a chain connection is formed between the nail base piece and the movable connecting piece.

[0026] In one of the technical solutions, in order to match the shape of the bionic nail piece and improve the three-dimensional freedom of movement, the bottom surface of the movable connecting member is oriented in the same direction as the prismatic base of the nail piece base.

[0027] In one of the technical solutions, in order to match the shape of the bionic nail plate and improve the three-dimensional freedom of movement, the projection of the top prism on the prismatic base coincides with the long diagonal line on the prismatic base.

[0028] In one of the technical solutions, in order to match the shape of the bionic nail plate and improve the three-dimensional freedom of movement, the bottom surface of the movable connecting part is a square bottom surface, and the side length of the bottom surface is 1 / 4 to 1 / 2 of the long diagonal length of the prismatic base, and the height of the movable connecting part is 2 / 5 to 1 / 2 of the side length of the bottom surface.

[0029] A bionic phosphorus armor component can be formed by connecting the armor base components and the movable connecting components in a plurality of bionic phosphorus armor-type stress dispersion modular components with three-dimensional freedom of movement through a chain.

[0030] The technical solution of the present invention has the following beneficial effects:

[0031] 1. This invention provides a bionic phosphorus armor-like stress-dispersing modular component with three-dimensional freedom of movement. Its interlocking structure, formed by chain-link connections, enables reversible switching between soft and hard states, providing adjustable mechanical properties. The combination of bionic armor plates and modular scale armor not only achieves a rigid-flexible transition but also further dissipates stress through the overlapping structure of the bionic armor plates, improving impact resistance.

[0032] 2. The present invention provides a bionic phosphorus armor-like stress dispersion modular component with three-dimensional freedom of movement. The finite element simulation results demonstrate the stress distribution and transfer characteristics of the bionic armor plate under vertical impact load.

[0033] 3. The present invention provides a bionic nail plate with high puncture resistance. By utilizing its optimized curved surface design, its stress absorption effect is greatly improved, and it has significantly excellent puncture resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The present invention will be further explained in detail below with reference to the examples. However, it will be appreciated by those skilled in the art that these examples are provided for illustrative purposes only and are not intended to limit the present invention.

[0062] Example 1

[0063] like Figures 1 to 19 As shown in Example 1, a bionic phosphorus armor-like stress dispersion modular component with three-dimensional freedom of movement mainly includes a bionic armor plate with high puncture resistance and a combined base module.

[0064] The shape of the bionic nail plate is mainly a geometric body composed of a rhombus bottom surface 1, a symmetrical hyperbolic outer nail surface 2 and a symmetrical hyperbolic inner nail surface 3;

[0065] On the axial section 4 of the geometric body perpendicular to the rhombus base 1 and passing through the short diagonal of the rhombus base 1, the contour line of the axial section 4 is composed of the short diagonal, the outer armor curve and the inner armor curve. The contour line of the axial section 4 is constructed with the intersection point of the inner armor curve and the short diagonal as the coordinate origin (0, 0) to construct a rectangular coordinate system. The coordinates of the intersection point of the outer armor curve and the short diagonal are (16, 0). The curve formula of the outer armor curve is y=-(5 / 128)x 2 +10; the curve formula of the inner nail curve is y=-0.1673x 2 -2.2257x;

[0066] On the inner and outer dividing sections 5 of the geometric body determined by the intersection of the outer armor curve and the inner armor curve and the long diagonal line of the rhombus bottom surface 1, the contour lines of the inner and outer dividing sections 5 are composed of the long diagonal line and the inner and outer dividing curves. The contour lines of the inner and outer dividing sections 5 are constructed with the center point of the long diagonal line as the coordinate origin (0, 0) to construct a rectangular coordinate system, and the coordinates of the endpoints of the long diagonal line are (-16, 0) and (16, 0) respectively; the curve formula of the inner and outer dividing curves is y=-(17.25 / 256)x 2 +17.25;

[0067] The intersection of the rhombus bottom surface 1, the inner nail surface 3 and the outer nail surface 2 on the geometric body is a rounded edge; the outer nail curve, the inner nail curve and the inner and outer dividing curves on the geometric body are rounded edges;

[0068] The outer carapace surface is composed of two symmetrical curved surfaces A2-A. The edge of the curved surface A2-A is composed of the inner and outer dividing curves, the outer carapace curve and the edge of the rhombus bottom surface adjacent to the outer carapace curve. The curved surface A2-A is a concave curved surface, and its specific shape is as follows: Figure 7 As shown, or the specific shape of the surface A2-A is as follows Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown in any one or more of the Figures;

[0069] The inner nail surface is composed of two symmetrical curved surfaces B3-B. The edge of the curved surface B3-B is composed of the inner and outer dividing curves, the inner nail curve and the edge of the rhombus bottom surface adjacent to the inner nail curve. The curved surface B3-B is a concave surface, and its specific shape is as follows: Figure 7 As shown, or the specific shape of surface B is as follows Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown in any one or more of the Figures;

[0070] The combined base module is mainly composed of a nail base member 6 and a movable connecting member 9.

[0071] The nail base member 6 is a quadrangular pyramid-shaped frame structure, comprising a prismatic base 8 for fixed connection to the prismatic base of the bionic nail. When the rhombus-shaped base 8 serves as the lower base of the quadrangular pyramid, the upper base corresponding to the lower base is formed by a single top prism 7. The side prisms fixedly connected to the center point and the ends of the top prism 7 are respectively connected to the four corners of the prismatic base 8. The angle between the side prisms adjacent to the long diagonal line of the prismatic base 8 and the prismatic base 8 is 45°.

[0072] The movable connecting member 9 is a quadrangular pyramid-shaped frame structure. The side prisms on the nail base member 6 pass through the square bottom surface 10 of the movable connecting member 9 and the hollow side surfaces, so that the nail base member 6 and the movable connecting member 9 form a chain connection.

[0073] The bottom surface of the movable connecting member 9 is oriented in the same direction as the prismatic base of the nail base member 6; the projection of the top prism 7 on the prismatic base 8 coincides with the long diagonal line on the prismatic base 8; the movable connecting member 9 has a square bottom surface 10, and the side length of the square bottom surface 10 is 2 / 5 of the length of the long diagonal line on the prismatic base 8, and the height of the movable connecting member 9 is 9 / 20 of the side length of the square bottom surface 10.

[0074] like Figures 20-21 As shown, a bionic nail plate with high puncture resistance and a modular base module are combined, which includes two movable connecting parts. The chain connection between the nail plate base part and the movable connecting parts can form a bionic phosphorus armor part.

[0075] like Figures 24-25 As shown, the bionic phosphorus armor component prepared by 3D printing has excellent performance in bending tests.

[0076] like Figure 22 Figure 2 shows finite element simulation results, demonstrating the stress distribution and transfer characteristics of the bionic nail plates under vertical impact loads. The staggered arrangement of the plates helps disperse stress from the central plate to the surrounding plates. Initially, vertical stress is concentrated on the central plate, forming a localized area of ​​high stress. However, as the load continues, the structural design gradually promotes stress redistribution, allowing the adjacent plates in contact with the central plate to absorb and mitigate the impact force.

[0077] This stress transfer mechanism is represented by a color gradient transitioning from red in the center to cool tones outward, demonstrating the gradual dissipation of stress. The staggered arrangement provides channels for radial force propagation, thereby mitigating impacts on any single location within the structure. This demonstrates that the bionic nail plate structure provided by the present invention enhances the material's impact resistance because the dispersed stress reduces the likelihood of damage in the central region and distributes the load over a larger area. This effect is particularly important for applications that require resistance to multiple stresses or impacts.

[0078] The structure presented in this paper highlights the effectiveness of biomimetic design in engineering applications, demonstrating how the arrangement of biomimetic plates can help achieve superior stress distribution. Simulation results confirm that this design approach can effectively reduce local stress, which is crucial for developing high-performance materials in impact-prone environments.

[0079] like Figure 23 As shown in the figure, a ball drop test was conducted to compare the dynamic cushioning capabilities of the bionic phosphorus armor components constructed from bionic nail plates. A 1.95-gram steel ball was naturally released from a height of approximately 30 cm and impacted a 3D-printed bionic phosphorus armor component and an unstructured flat plate made of the same material. The ball's falling process and maximum rebound height were filmed and recorded.

[0080] The experiment proved that the scale armor structure with overlapping units can effectively absorb kinetic energy.

[0081] The magnitude of gravitational potential energy can be calculated using the following formula:

[0082] E=mgh

[0083] The gravitational potential energy released by a 1.95-gram steel ball at a distance of approximately 30 cm is converted into 0.005733 J of kinetic energy. After landing on the bionic phosphorus armor structure, the steel ball did not rebound, indicating that the kinetic energy was completely absorbed by the structure. In contrast, when the steel ball landed on a flat plate made of the same material, it bounced 10 cm, indicating that only 0.003822 J of kinetic energy (66% of the total kinetic energy) was absorbed.

[0084] Therefore, the bionic phosphorus armor component provided in Example 1 of the present invention can effectively reduce the impact by more than 33% through stress dispersion.

[0085] The above embodiments are preferred implementations of the present invention, but the implementations of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered equivalent replacement methods and are included in the scope of protection of the present invention.
