[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1, reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a bionic protective structure, and the bionic protective structure includes a base layer 100 and a scale layer 200 .

[0042] Specifically, the base layer 100 is a regular hexagonal prism, which is manufactured in one step by 3D printing technology, and the materials used include but are not limited to plastics such as PLA and ABS, metals and alloys such as aluminum and stainless steel, ceramics, resins, and biomaterials;

[0043] The base layer 100 is hexagonally inlaid on the attachment layer K, and the attachment layer K is composed of a flexible fabric, and the materials used include but are not limited to natural fiber fabrics such as cotton, linen, silk, and wool, as well as synthetic fiber fabrics such as polyester, nylon, acrylic, and blended fabrics, a mixture of natural and synthetic fibers;

[0044] The base layer 100 and the attachment layer K are fixedly connected, and the connection methods used include but are not limited to heat pressing, adhesives and sewing;

[0045] The bottom of the scale layer 200 is fixedly connected to the base layer 100, and can also be connected by heat pressing, adhesives, sewing and other methods, or the base layer 100 and the scale layer 200 can be integrally formed during 3D printing;

[0046] There is a gap between two adjacent base layers 100. With the flexible attachment layer K, the base layers 100 can have a certain offset range. The effect on the entire attachment layer K on which the base layers 100 are installed allows the entire structure to perfectly fit the curved surface with a small curvature.

[0047] In order to prevent the existence of this seam from reducing the strength of the device, a scale layer 200 is provided on the base layer 100. There is a base layer 100 at each end of the seam, and each base layer 100 has a scale layer 200. The top of the scale layer 200 protrudes from the base layer 100, and the projection of the scale layer 200 on the top surface of the base layer 100 completely covers the seam in this direction. In this way, while retaining the flexibility of the device, the gap between the base layers 100 is prevented from being pierced or scratched.

[0048] At the same time, when the base layer 100 of the regular hexagonal prism is inlaid with a seam on a plane, the seam formed will not form a long straight side like a square or an equilateral triangle, but the long straight side is avoided, thus avoiding the slippage of the base layer 100 on the adhesion layer K, further enhancing the stability and deformation resistance of the overall structure.

[0049] In more detail, the top surface of the base layer 100 has a side length of 20 mm and a height of 4 mm, and the thickness of the scale layer 200 is 3 to 4 mm;

[0050] When in use, each base layer 100 is surrounded by six other base layers 100, and there is a certain distance between two adjacent base layers 100 to ensure that when the base layers 100 are densely laid on the adhesion layer K, one base layer 100 has a range of movement, and the scale layer 200 arranged on the top surface of the base layer 100 protrudes from the top surface of the base layer 100 and covers the gap between two adjacent base layers 100.

[0051] Example 2, reference Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0052] The top surface of the base layer 100 and the bottom surface of the scale layer 200 are opposite to each other. The top surface of each base layer 100 has two first sides A1, two second sides A2 and two third sides A3. Each scale layer 200 has two first end surfaces 201, two second end surfaces 202 and two third end surfaces 203. The end surfaces of the scale layer 200 are symmetrical with a straight line L formed by passing through the coincidence points of the two first sides A1 and the two third sides A3 along the base layer 100. The projection of the top edge of the second end surface 202 on the top surface of the base layer 100 coincides with the straight line L.

[0053] The base layer 100 can be periodically paved to ensure that the entire protective structure does not leave irregular gaps, and cooperates with the attachment layer K to form a solid and stable structure. Three gaps and a vertex are formed at the joints of every three base layers 100, and the distance between every two gaps is 120 degrees. This paving method avoids the long straight edges that will be formed when squares and equilateral triangles are paved, ensuring that the base layer 100 will not shift, further enhancing the stability and deformation resistance of the overall structure. This design enables the hexagonal base to remain stable when subjected to external pressure and is not easily deformed or broken.

[0054] The inclined shape of the scale layer 200 can effectively remove the force applied by the outside world, reduce local pressure concentration, and thus reduce the risk of damage. The inclined surface of each scale can disperse the force to a wider area to avoid excessive force on a single point. The second end face 202 of the quadrilateral on the scale layer 200 can increase the thickness of the overall structure of the scale layer 200, while covering the gaps between the base layer 100, providing an additional protective layer to prevent small objects or punctures from penetrating the protective layer and entering the interior. This feature enables the structure to provide more comprehensive protection when facing various complex environments.

[0055] The flexible adhesion layer K can ensure that when the device is impacted, the force energy received on the scale layer 200 will be directly transmitted to the base layer 100 first, and then transmitted to the adhesion layer K by the base layer 100. The flexible adhesion layer K produces a certain deformation, causing the base layer 100 and the scale layer 200 to be displaced, so that the scale layer 200 contacts the surrounding scale layers 200, thereby quickly dispersing the force to the surroundings, thereby improving the impact resistance and puncture resistance of the overall structure. This force dispersion mechanism enables the scale structure to effectively absorb and disperse external forces when facing sharp objects or strong impacts, thereby avoiding damage to a single scale.

[0056] The protective layer 300 is a hard shell bonded to the surface of the scale layer 200. The material used is metal or ceramic to improve the puncture resistance.

[0057] When in use, the flexible attachment layer K allows the base layer 100 and the scale layer 200 to be arranged repeatedly and at a certain distance, so that when the structure is bent or twisted, it can flexibly adapt to deformation like snake scales or pangolin scales. This arrangement allows the base layer 100 and the scale layer 200 to make small independent movements in multiple directions, thereby achieving overall flexible deformation;

[0058] Each group of connected base layers 100 and scale layers 200 can not only move independently, but also provide support and restriction for the surrounding base layers 100 and scale layers 200, avoiding the base layer 100 from shifting alone, ensuring that the structure can maintain overall stability and continuity during flexural deformation, and preventing a single base layer 100 and scale layer 200 from detaching or dislocating.

[0059] Also, since there can be slight sliding and displacement between each set of connected base layers 100 and scale layers 200, this structure can adapt to a variety of complex geometric shapes and dynamic movements. Whether in different situations such as bending, twisting or stretching, this structure can adapt well and maintain protective performance.

[0060] In summary, the flexible arrangement of this protective structure enables the base layer 100 and the scale layer 200 to move independently and adapt to multi-directional deformation. The local stress dispersion mechanism effectively improves the impact resistance and prevents local damage. The mutual support and restriction between the scales ensures the stability and continuity of the structure during deformation, preventing detachment or dislocation. In addition, this structure can adapt to a variety of complex geometric shapes and dynamic movements, maintaining excellent protective performance and high flexibility. At the same time, the overlapping design of the scale layer 200 effectively covers the gaps between the base layer 100, further enhancing the overall puncture resistance and durability. These advantages make the device excellent in terms of protective performance, flexibility, stability and adaptability, and have a wide range of application potential.

[0061] Example 3, reference Figures 9 to 12, which is the third embodiment of the present invention, is based on the previous embodiment, except that the base layer 100 is cylindrical and the scale layer 200 is a curved cone.

[0062] The cylindrical base layer 100 is inlaid in the densest manner on a plane. Each base layer 100 is surrounded by six base layers 100. Similarly, two adjacent base layers 100 are not directly attached to each other, so as to retain the flexible movement of the structure.

[0063] The axis of the curved conical flaky layer 200 is perpendicular to the circular surface of the top surface of the base layer 100 and is located at the center of the circle of the top surface of the base layer 100 when the axis moves away from the circular surface of the top surface of the base layer 100, and the angle between the axis and the circular surface of the top surface of the base layer 100 becomes smaller and smaller, until the projection of the end of the axis away from the circular surface of the top surface of the base layer 100 on the circular surface of the top surface of the base layer 100 does not fall on the circle of the top surface of the base layer 100 and protrudes a certain distance, so that the curved conical flaky layer 200 also fills the gaps between the cylindrical base layers 100.

[0064] Example 4, reference Figure 1 , Figure 3 and Fig.13 , which is the fourth embodiment of the present invention, and this embodiment is based on the first embodiment.

[0065] Specifically, the bottom surface of the scale layer 200 is fixed on the top surface of the base layer 100, and the edge of the bottom surface of the scale layer 200 is matched with the edge of the top surface of the base layer 100. First, the scale layer 200 and the base layer 100 are matched as a complete splicing unit.

[0066] A line close to the boundary of the adhesion layer K is selected as the starting line K1 , and the center of the base layer 100 passes through the starting line K1 .

[0067] The base layer 100 is fixed on the attachment layer K along the starting line K1, and the distance between the base layers 100 is d1, so that the top edge of the second end surface 202 of the scale layer 200 is closer to the boundary of the attachment layer K, forming a starting column J1, the base layers 100 are evenly arranged, and the space below the top edge of the second end surface 202 of the scale layer 200 is empty.

[0068] In the starting column J1, a new column of substrate layers 100 is set between every two adjacent substrate layers 100 in the direction away from the starting line K1, and the distance between the substrate layer 100 and the substrate layer 100 of the adjacent starting column J1 is d1, which serves as the second column J2, and the scale layer 200 of the second column J2 covers the gaps between the substrate layers 100 of the starting column J1. When the installation position range on the attachment layer K is a rectangle, the number of substrate layers 100 in the second column J2 differs from that in the starting column J1 by 1, and the number of substrate layers 100 in each column in the odd-numbered columns is the same, and the number of substrate layers 100 in each column in the even-numbered columns is the same; when the installation position range on the attachment layer K is not a rectangle, the columns are arranged according to the shape of the installation position range.

[0069] The base layers 100 of the next column are added in sequence in a direction away from the starting line K1 , in such a way that the top edge of the second end surface 202 of each new column of the scale layer 200 covers the gaps between the base layers 100 of the previous column.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
