[0031] The present utility model provides a sports equipment buffer structure and a sports equipment. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In existing sports equipment, in order to reduce the human body injuries caused by collisions during sports, it is often necessary to set up buffer structures at specific positions of the sports equipment to absorb the kinetic energy generated during sports so as to provide sports protection. However, for different sports equipment, the positions where buffer structures need to be set are different, and the required support performance or resilience performance of the buffer structures is also different. In this case, whether it is filling with foaming materials or forming an airbag structure by die stamping, it cannot well meet the requirements of different sports equipment for the buffer structures of sports equipment in different scenarios, nor can it fill high-pressure air into the airbag structure. The utility model integrally forms a buffer structure of sports equipment by using 3D printing technology, which includes a support structure and an airbag structure with internal pressure filled in the support structure, so as to provide the required resilience performance and support performance for the buffer structure of the sports equipment. Through 3D printing, the bondage of the mold can be broken, and by adjusting the design of the support structure, the required support performance and resilience performance can be provided for different sports equipment in different scenarios, with a wide application range and being conducive to commercial promotion.

[0033] In the buffer structure of the sports equipment of the utility model, the support structure is composed of a framework and a cavity surrounded by the framework. The overall framework of the support structure is formed by the framework, and the airbag structure with internal pressure is filled in the cavity surrounded by the framework, so as to provide the required support performance and resilience performance for the buffer structure of the sports equipment. Specifically, the framework is integrally formed by 3D printing technology, and the cavity and the airbag structure with internal pressure filled in the cavity are naturally formed during the printing process. The support force is provided for the buffer structure of the sports equipment by the framework and the airbag structure with internal pressure together. Through a preset model, the required framework structure and airbag structure with internal pressure can be 3D printed, so as to provide the required support performance or resilience performance for different sports equipment in different scenarios. Optionally, the framework is formed by connecting multiple repeated cell structures, and a cavity is formed in each cell structure, and the airbag structure with internal pressure corresponds to the cavity one by one; optionally, the framework is a curved surface lattice structure formed by a continuous curved surface, the cavity is formed by wrapping with the curved surface, and the airbag structure with internal pressure is filled in the cavity. By designing frameworks with different shapes and states, the required support performance or resilience performance of the sports equipment is provided.

[0034] Further, a high-pressure gas is filled in the airbag structure with internal pressure, and the airbag structure with internal pressure is printed as needed to form an integrally formed ellipsoidal, spherical, octahedral or cubic structure, so as to provide the required support performance or resilience performance. Specifically, air with a pressure greater than 1 atm is filled in the airbag structure with internal pressure, so as to ensure that the pressure in the airbag structure with internal pressure is greater than the atmospheric pressure, thereby providing better support performance and resilience performance for the sports equipment.

[0035] Specifically, as Figure 1 , Figure 6 and Figure 10 shown, the sports equipment buffer structure of the present invention includes a support structure 100 and an airbag structure 200 with internal pressure. The support structure 100 surrounds a cavity through a framework 110, and the airbag structure 200 with internal pressure is fixedly connected to the framework 110 and filled in the cavity. Thus, when the sports equipment buffer structure is stressed, the framework 110 and the airbag structure 200 with internal pressure provide support force to ensure the support performance and resilience performance of the sports equipment buffer structure. Optionally, high-pressure air with a pressure greater than 1 atm is filled in the airbag structure 200 with internal pressure, so as to provide better support performance and resilience performance for the sports equipment buffer structure.

[0036] In one embodiment, as Figure 5 and Figure 9 shown, the framework 110 is composed of a plurality of repeating unit cell structures 120. Each unit cell structure 120 forms a cavity inside for filling the airbag structure 200 with internal pressure, and the cavities correspond to the airbag structures 200 with internal pressure one by one. Specifically, the unit cell structure 120 is formed by connecting rod structures 121 end to end, and the rod structures 121 have the same size and shape. Optionally, the rod structure 121 is a cylindrical short rod structure with the same length and diameter. The rod structures 121 are connected end to end and combined at different angles to form unit cell structures different structures, thereby forming different designs of the framework 110. By changing the shapes of different unit cell structures 120 in the framework 110, the support structure 100 that can provide different support forces is obtained, so that the application range of the sports equipment buffer structure is wider.

[0037] Optionally, the diameter of the rod structure 121 is 0.1 mm - 1 mm, and the length of the rod structure 121 is 1 mm - 10 mm. By adjusting the length or diameter of the rod structure 121 in the cell structure 120, the reaction force of the skeleton 110 against the stress in different directions can be adjusted. Optionally, the rod structure 121 is a hollow cylindrical short rod structure, and the internal cavity of the rod structure 121 is filled with high-pressure air with a pressure greater than 1 atm, so that when the sports equipment buffer structure is stressed, better support performance and resilience performance can be provided through the skeleton 110 of the support structure 100.

[0038] In one embodiment, as Figure 11 and Figure 12 shown, the skeleton 110 is a lattice structure formed by continuous curved surfaces surrounding and wrapping, and the cavity formed by the continuous curved surface wrapping is filled with the airbag structure 200 having internal pressure. Optionally, the continuous curved surface surrounds and wraps to form a Schwarz P lattice structure or a spiral icosahedron structure, and the airbag structure 200 having internal pressure is filled in the cavity formed by the continuous curved surface. Further, the continuous curved surface wraps to form a sealed cavity inside the skeleton 110, and high-pressure air with a pressure greater than 1 atm is filled in the cavity to provide the required support performance and resilience performance without setting the airbag structure 200 having internal pressure.

[0039] In one embodiment, as Figure 3 shown, the airbag structure 200 having internal pressure is an ellipsoidal structure. The cavity inside the skeleton 110 is filled with the airbag structure 200 having the same size and the same shape, and the airbag structures 200 having internal pressure are also tangent to each other directly and fixedly connected to stack into a regular cuboid-shaped structure, so that the sports equipment buffer structure has better support performance and resilience performance in a specific direction. By surrounding the airbag structure 200 having internal pressure with the skeleton 110 and adjusting the shape of the skeleton 110, the required support performance and resilience performance can be ensured in any direction for the sports equipment buffer structure.

[0040] Optionally, according to the requirements of the sports equipment buffering structure, while keeping the skeleton 110 unchanged, by adjusting the side wall thickness of the airbag structure 200 with internal pressure, different supporting forces can be provided for the sports equipment buffering structure in different scenarios. For different sports types, different sports parts, and users in different physical states, the requirements for the supporting performance and resilience performance in the supporting forces that the sports equipment needs to provide in different areas are different. For example, during running and jumping, as the buffering structure of the sole, the areas corresponding to the sole and heel should mainly provide resilience for the user on the basis of landing buffering, that is, shorten the rebound time of the cavity structure to assist in running and jumping force; while the areas corresponding to the toes and the instep of the foot should mainly provide support for the user on the basis of landing buffering, that is, reduce the travel when the cavity structure is compressed to reduce the burden on the foot muscles. Optionally, the thickness of the airbag structure 200 with internal pressure is 0.1 mm - 2 mm. When the skeleton 110 remains unchanged, when a supporting force with better resilience performance is required, the thickness of the airbag structure 200 with internal pressure is reduced, thereby increasing the volume of the airbag cavity in the airbag structure 200 with internal pressure and accelerating the rebound speed to shorten the rebound time; when a supporting force with better supporting performance is required, the thickness of the airbag structure 200 with internal pressure is increased, thereby reducing the compressible space of the airbag structure 200 with internal pressure to reduce the travel when compressed and provide better supporting performance.

[0041] In one embodiment, by adjusting the difference in hardness between the 3D printing material of the skeleton 110 and the 3D printing material of the airbag structure 200 with internal pressure in the support structure 100, the support performance and resilience performance of the sports equipment buffering structure are adjusted. Taking the 3D printing material with a modulus of 1 MPa as a pure soft material and the 3D printing material with a modulus of 1 GPa as a pure hard material, the skeleton 110 is printed and prepared by the pure hard material, and the airbag structure 200 with internal pressure is printed and prepared by the pure soft material, so as to not only ensure the stiffness of the sports equipment buffering structure but also provide corresponding elasticity, and thus corresponding support performance or resilience performance can be provided as needed.

[0042] The utility model provides a support structure and an airbag structure with internal pressure in a buffer structure for sports equipment. The cavity formed by the framework of the support structure is filled with the airbag structure with internal pressure, and high-pressure air is filled in the airbag structure, so as to provide the required support performance and resilience performance for the buffer structure of the sports equipment. By adjusting the shape and size of the framework, support structures with different structures can be obtained, and at the same time, the internal pressure of the airbag structure with internal pressure is adjusted, so as to provide different supporting forces for the buffer structure of the sports equipment under different requirements, thereby expanding the application range of the buffer structure of the sports equipment in different sports scenarios.

[0043] The following combines the accompanying drawings and specific embodiments to illustrate the situation where the framework 110 in the support structure 100 is designed in different states when the airbag structure 200 with internal pressure is ellipsoidally arranged in the present utility model.

[0044] Embodiment 1

[0045] As Figure 1 and Figure 2 shown, the framework 110 is formed by sequentially connecting cell structures 120 corresponding to the Kelvin lattice structure. A cavity is formed in each cell structure 120 and filled with an airbag structure 200 with internal pressure. The airbag structure 200 with internal pressure is ellipsoidal and filled with high-pressure air with a pressure greater than 1 atm. Specifically, as Figure 4 and Figure 5 shown, one cell structure 120 includes 36 rod structures 121. The rod structures 121 are connected end to end to form a Kelvin lattice structure, where the Kelvin lattice structure includes 6 quadrilaterals and 8 hexagons. Each quadrilateral is adjacent to 4 hexagons, and each hexagon is adjacent to 3 quadrilaterals and 3 hexagons. An airbag structure 200 with internal pressure is filled in one cell structure 120, and at the same time, an airbag structure 200 with internal pressure is also filled between two adjacent cell structures 120. Thus, when the buffer structure of the sports equipment is subjected to pressure in any direction, the support structure 100 and the airbag structure 200 with internal pressure can both provide the same supporting force, thereby improving the support performance and resilience performance of the buffer structure of the sports equipment.

[0046] Embodiment 2

[0047] As Figure 6 and Figure 7As shown, the framework 110 is composed of a combination of hexahedral cell structures 120 formed by attaching the bottoms of two regular tetrahedrons. A cavity is formed within the cell structure 120 and filled with one airbag structure 200 having internal pressure. The airbag structure 200 having internal pressure is ellipsoidal and filled with high-pressure air with a pressure greater than 1 atm. Specifically, as Figure 8 and Figure 9 shown, one cell structure 120 includes 9 rod structures 121. The rod structures 121 are connected end to end to form a hexahedron formed by attaching the bottoms of two regular tetrahedrons. The rod structures 121 form the nine edges of the hexahedron. The framework 110 and the airbag structure 200 having internal pressure provide support for the sports equipment buffer structure, thereby improving the support performance and resilience performance of the sports equipment buffer structure.

[0048] Embodiment III

[0049] As Figure 10 and Figure 11 shown, the framework 110 is a Schwarz P structure formed by surrounding and wrapping with a continuous curved surface. The airbag structure 200 having internal pressure fills the void surrounded by the inner curved surface of the Schwarz P structure. Optionally, the airbag structure 200 having internal pressure is ellipsoidal and filled with high-pressure air with a pressure greater than 1 atm. Specifically, as Figure 11 and Figure 12 [[ID=L18]]shown, the overall outer contour of the framework 110 is cube-shaped. A cavity is formed inside the framework 110 by surrounding it with a spiral curved surface, and the airbag structure 200 having internal pressure is filled in the cavity, and the airbag structure 200 having internal pressure abuts against the curved surface. Thus, the framework 110 and the airbag structure 200 having internal pressure jointly provide support for the sports equipment buffer structure, providing the required support performance and resilience performance for the sports equipment buffer structure.

[0050] Optionally, a closed cavity is formed by surrounding and wrapping with a curved surface inside the framework 110, and high-pressure air with a pressure greater than 1 atm is filled in the cavity. Thus, only through the framework 110, the required support performance and resilience performance can be provided for the sports equipment buffer structure without adding the airbag structure 200 having internal pressure.

[0051] In one embodiment, the present utility model further provides a sports equipment, including the sports equipment buffer structure as described above. The sports equipment includes sports shoes, helmets, knee pads, braces, belts and other equipment, and the sports equipment buffer structure provides different elastic or supporting force effects in different regions, so as to meet the specific requirements of different sports equipment buffer materials, with a wider application range, not limited by molds, and is conducive to market promotion.

[0052] In summary, the present utility model discloses a sports equipment buffer structure, including: a support structure and an airbag structure with internal pressure, wherein the support structure includes a skeleton forming the support structure and a cavity surrounded by the skeleton, and the airbag structure with internal pressure is fixedly connected to the skeleton and fills the cavity to provide a supporting force when the sports equipment buffer structure is stressed.

[0053] It should be understood that the application of the present utility model is not limited to the above examples.
