[0002] The multilevel honeycomb structure is a kind of structure design formed by combining honeycomb units of different scales or different geometric shapes together, which can significantly improve mechanical properties (such as strength, stiffness and energy absorption capacity) while maintaining lightweight.
[0003] In the field of modern material science and engineering, honeycomb structure has been widely used in many industries due to its unique geometric shape and excellent performance. Honeycomb structure is a kind of bionic structure, which imitates the hexagonal grid shape of honeycomb in nature, and has the characteristics of lightweight, high strength and high stiffness.

For example, when subjected to impact load, the energy absorption efficiency of single-layer honeycomb structure is low, and it cannot fully exert its potential energy absorption capacity. At the same time, simple double-layer structure lacks sufficient flexibility and adaptability when dealing with loads in different directions, so a multilevel honeycomb structure is needed. SUMMARY

[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.
[0022] Example one
[0023] As Figure 1 , and 2 and Figure 3As shown, a multi-level honeycomb structure includes a hexagonal shell 1, the hexagonal shell 1 is hollow, and the hexagonal shell 1 is fixedly connected with six honeycomb plates 2, the six honeycomb plates 2 are fixedly connected with a connecting shell 5, the connecting shell 5 is fixedly connected with a reinforcing mechanism 4 between the outer middle part of the connecting shell 5 and the inner middle part of the hexagonal shell 1, and the connecting shell 5 is fixedly connected with the connecting shell 5.
[0024] In this case Figure 2 It is integrated and can be made by 3D printing technology.
[0025] Figure 2 The multi-level design is composed of honeycomb units of different sizes, such as hexagonal shells 1, honeycomb plates 2 and connecting shells 5, which are combined to form a hierarchical structure design. This structure can significantly improve the mechanical properties such as strength, stiffness and energy absorption capacity, while maintaining the lightweight characteristics.
[0026] In the above, the large-scale honeycomb unit of the overall structure provides the main mechanical support, and the introduction of the medium-scale honeycomb structure at the wall or node of the macro honeycomb unit can enhance the local strength.
[0027] In the above, through the multi-scale design, the stress distribution can be optimized, the overall strength and stiffness can be improved, and the structure can absorb more energy through different levels of deformation when subjected to impact. The multi-level design improves the performance while maintaining a low density.
[0028] The present scheme Figure 1 And Figure 3 The reinforcing mechanism 4 and the supporting mechanism 3 can further increase the compression resistance, bending resistance and shear resistance of the device, enhance the local stiffness and strength, optimize the stress distribution, and further improve the local strength and fatigue resistance of the device.
[0029] Example two
[0030] Further, in order to achieve the purpose of the reinforcing mechanism 4 and the supporting mechanism 3 to enhance the compression resistance, bending resistance and shear resistance of the device, refer to Figure 4 And Figure 5 The reinforcing mechanism 4 includes reinforcing ribs 41 fixedly connected between the hexagonal shell 1 and the connecting shell 5, and T-shaped holes 42 are formed in the upper end of the reinforcing ribs 41;
[0031] Further, the top edge of the reinforcing rib 41 is connected with the inner edge of the hexagonal shell 1, and the top edge of the reinforcing rib 41 is connected with the outer edge of the connecting shell 5.
[0032] Further, the supporting mechanism 3 includes a supporting rod 31 located at the center position of the connecting shell 5, and three supporting plates 32 are arranged in a ring shape on the outer surface of the supporting rod 31.
[0033] Further, the three support plates 32 are connected with the inner cavity of the connecting shell 5.
[0034] In the above, the top edge and the bottom edge of the reinforcing rib 41 are in a golden ratio of 1:1.618, and the golden ratio design can make the stress evenly distributed in the reinforcing rib 41, reduce stress concentration, and increase the bending stiffness and stability of the device.
[0035] In the above, the reinforcing rib 41 is in a hollow state by the design of the T-shaped hole 42, so that the reinforcing rib 41 reduces the material usage, and thus the structural weight can be reduced. Under the same weight, the strength of the hollow reinforcing rib 41 is usually higher than that of the solid reinforcing rib 41, and thus the compression strength of the device is ensured in addition to the lightweight design of the device.
[0036] In the above, the support rod 31 and the support plate 32 can significantly improve the mechanical properties such as strength, stiffness and stability of the structure; the support rod 31 and the support plate 32 have excellent stress distribution ability and anti-deformation ability due to their geometric characteristics, and are particularly suitable for application scenarios requiring high bearing capacity and impact resistance. The triangle is the most stable shape in geometry, which can effectively disperse stress and reduce local stress concentration, thereby reducing the stress concentration of the honeycomb unit and improving the overall strength.
[0037] When the device is subjected to compression, bending or shear load, the support rod 31 and the support plate 32 can provide additional support to prevent structural instability, especially under dynamic load such as vibration and impact, the support mechanism 3 can reduce the deformation of the structure.
[0038] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
