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 dispersion modular component with three-dimensional freedom of movement. Background Art

[0002] In order to protect themselves from the surrounding environment and predators, creatures in nature have evolved a variety of biological armor over a long period of time. From the hard shells of mollusks to the thick helmet-like skulls of dinosaurs, armor structures not only need to provide mechanical protection, but also play a variety of roles such as fluid dynamic drag reduction, coloring, and optical, chemical, and mechanical sensing. However, the flexibility of most biological armors is limited due to their rigid and hard scale structures. Therefore, ensuring protective performance while ensuring flexibility has become the convergent evolutionary direction of various organisms with scale armor protection structures. The solution given by nature is to replace larger units with scaly armor composed of small, repetitive units, like 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 called osteoderms (e.g. turtles, lizards, alligators, and armadillos). The former, especially fish scales, achieve both protection and flexibility through relative rotation, sliding, and bending between 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. turtles).

[0004] There are also many examples in human history of achieving a combination of protection and flexibility through structural design, from the heavy medieval armor to the flexible and lightweight traditional Chinese chain mail structure, to the bionic flexible protective structure developed in modern times. However, most previous studies on biological flexible scale armor focused on simplifying the shape elements of scales, and combining puncture-proof materials to form scale structures with two-dimensional design elements such as planes, or combining soft substrates to construct protective fabrics with woven structures.

[0005] Although the simplified imitation of biological scale shape elements in the existing technology has achieved certain research and application results, 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 will 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 structure. Therefore, if there is a bionic nail 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 view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a bionic phosphorus armor-type stress dispersion modular component with three-dimensional freedom of movement. The modular component of the present invention is connected by a chain to form an interlocking structure, which can achieve reversible switching between soft and hard states and has adjustable mechanical properties. At the same time, the combination of bionic armor plates and modular scale armor structures can not only achieve rigid-flexible transformation, but also further achieve stress dissipation through the overlapping structure of bionic armor plates, thereby improving the impact resistance between them.

[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, an outer nail surface in a symmetrical hyperbolic shape, and an inner nail surface in a symmetrical hyperbolic shape;

[0010] On the 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. The contour line of the axial section is constructed into a rectangular coordinate system 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 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 split 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 bottom surface, the contour lines of the inner and outer split sections are composed of the long diagonal and the inner and outer split curves, and the contour lines of the inner and outer split sections are constructed into a rectangular coordinate system 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 split curves is 0, the y value is 17 to 17.5, and the inner and outer split 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 inner and outer dividing curves, an 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, so as to realize the smooth structural design of the surface based on the modeling function of the three-dimensional modeling software.

[0016] In one of the technical solutions, based on the simulation experiment results, in order to ensure high puncture resistance and reduce the weight of the bionic nail plate as much as possible, the curved surface A is a concave curved 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 As shown in any one or more of the figures.

[0017] In this article, the edge of the surface B is composed of 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, so as to realize the smooth structural design of the surface based on the modeling function of the three-dimensional modeling software.

[0018] In one of the technical solutions, based on the simulation experiment results, in order to ensure high puncture resistance and reduce the weight of the bionic nail plate as much as possible, the curved surface B is a concave curved 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 As shown in any one or more of the figures.

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

[0020] In one of the technical solutions, based on the simulation experiment results, in order to improve the puncture resistance of the bionic nail plate, in a rectangular coordinate system constructed based on 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 rhombus 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 through functions such as rounding / cutting / 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 realized by functions such as rounding / cutting / cutting edges based on 3D modeling software.

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

[0024] The nail plate base is a frame-type structure in the shape of a quadrangular pyramid, which includes a prism base for fixedly connecting with the prism bottom surface of the bionic nail plate. When the rhombus base is used as the lower bottom surface of the quadrangular pyramid, the upper bottom surface corresponding to the lower bottom surface is composed of a single top prism, and the side prisms fixedly connected based on the center point and the two end heads of the top prism are respectively connected and fixed with the four corners of the prism base; the angle between the side prisms adjacent to the long diagonal line of the prism base and the prism base is 30-60°;

[0025] The movable connecting piece is a frame structure in the shape of a quadrangular pyramid, and the side prisms on the nail base piece pass through the bottom surface and the hollow side 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 plate base components and the movable connecting components in a plurality of bionic phosphorus armor-style 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. The present invention provides a bionic phosphorus armor-like stress dispersion modular component with three-dimensional freedom of movement. The interlocking structure formed by chain connection can achieve reversible switching between soft and hard states and has adjustable mechanical properties. At the same time, the combination of bionic armor plates and modular scale armor structure can not only achieve rigid-flexible transformation, but also further achieve stress dissipation through the overlapping structure of bionic armor plates, thereby improving the 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 loads.

[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 with reference to the following examples. However, it should be understood 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, Example 1 is a bionic phosphorus armor-like stress dispersion modular component with three-dimensional freedom of movement, mainly including 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, an outer nail surface 2 in a symmetrical hyperbolic shape, and an inner nail surface 3 in a symmetrical hyperbolic shape;

[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 into a rectangular coordinate system 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 curve formula of the outer armor curve is y=-(5 / 128)x 2 +10; the curve formula of the inner armor 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 of the rhombus bottom surface 1, the contour line of the inner and outer dividing sections 5 is composed of the long diagonal and the inner and outer dividing curves. The contour line of the inner and outer dividing section 5 is constructed into a rectangular coordinate system 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; the curve formula of the inner and outer dividing curve 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 armor surface is composed of two symmetrical curved surfaces A2-A, and the edge of the curved surface A2-A is composed of the inner and outer dividing curves, the outer armor curve and the edge of the rhombus bottom surface adjacent to the outer armor 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 B 3-B, and the edge of the curved surface B 3-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 B 3-B is a concave curved 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 base piece 6 and a movable connecting piece 9.

[0071] The nail base member 6 is a frame structure in the shape of a quadrangular pyramid, which includes a prism base 8 for fixedly connecting with the prism bottom surface of the bionic nail plate. When the rhombus base 8 is used as the lower bottom surface of the quadrangular pyramid, the upper bottom surface corresponding to the lower bottom surface is composed of a single top prism 7, and the side prisms fixedly connected to the center point and the two ends of the top prism 7 are respectively connected and fixed to the four corners of the prism base 8; the angle between the side prisms adjacent to the long diagonal line of the prism base 8 and the prism base 8 is 45°;

[0072] The movable connecting member 9 is a frame structure in the shape of a quadrangular pyramid, and the side prisms on the nail base member 6 pass through the four-sided bottom surface 10 and the hollowed-out side surfaces of the movable connecting member 9, 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 on the prismatic base 8; the movable connecting member 9 is 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 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 and the movable connecting parts can form a bionic phosphorus armor component.

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

[0076] like Fig. 22 The figure shows the finite element simulation results, which reflect the stress distribution and transfer characteristics of the bionic nail plate under vertical impact load. Among them, the staggered arrangement of the nail plates helps to disperse the stress from the central nail plate to the surrounding nail plates. Initially, the vertical stress is concentrated on the central nail plate, forming a local high stress area. However, as the load continues to act, the structural design gradually promotes the redistribution of stress, allowing the adjacent nail plates in contact with the central nail plate to absorb and relieve the impact force.

[0077] This stress transfer mechanism is represented by a color gradient that transitions from red in the center to cool tones outward, showing the gradual dissipation of stress. The staggered structure provides a channel for radial propagation of force, thereby reducing the impact of any single part of the structure. It is proved that the bionic nail plate structure provided by the present invention enhances the impact resistance of the material, because the dispersed stress reduces the possibility of damage in the central area and distributes the load over a larger area. This effect is particularly important for applications that need to withstand multiple stresses or impacts.

[0078] The structure provided by the invention highlights the effectiveness of bionic design in engineering applications, demonstrating how the arrangement of the plates of the bionic structure can help achieve superior stress distribution. The simulation results verify that the design method can effectively reduce local stress, which is crucial for developing high-performance materials in environments with frequent impacts.

[0079] like Fig.23 As shown in the figure, the dynamic buffering capacity of the bionic phosphorus armor parts composed of bionic armor pieces was compared through a ball drop test. A steel ball with a mass of 1.95 grams was naturally released from a height of about 30 cm and hit the 3D printed bionic phosphorus armor parts and the unstructured design flat plate made of the same material. The falling process of the ball and the maximum rebound height of the steel ball were filmed and recorded.

[0080] The experiment proved that the overlapping scale structure of 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 steel ball with a mass of 1.95 grams from about 30 cm is converted into kinetic energy of 0.005733 J. After the steel ball fell on the bionic phosphorus armor component, it did not rebound, indicating that the kinetic energy of the steel ball was completely absorbed by the structure. In contrast, when the steel ball fell on a flat plate structure made of the same material, it bounced 10 cm high, indicating that only 0.003822 J of kinetic energy was absorbed (accounting for 66% of the total kinetic energy).

[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 implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention.
