Description

Technical Field

[0001] This invention relates to the field of shock-absorbing and energy-absorbing buffers, and particularly to a reusable force-magnetic coupling shock-absorbing structure, belonging to the field of advanced structure and material design and manufacturing. Background Technology

[0002] In daily life and scientific research, many unpredictable, sudden, and rapid impact collisions or accidents occur. Especially in important engineering fields such as aerospace, military defense, and transportation, sudden accidents such as impact collisions occur frequently, are highly destructive, and have poor predictability, thus seriously threatening the safety of people and property. In order to reduce the threat posed by such unpredictable impact collisions to economic property and personal safety, a mechanical model with a mechanical structure capable of buffering external pressure is conceived.

[0003] Traditional buffer devices, once the overall structure is manufactured, cannot change parameters and are difficult to adjust flexibly; once a local structure is damaged or deformed, its performance is greatly reduced, making it difficult to reuse and resulting in high maintenance, repair, and replacement costs; and it is difficult to meet both the needs of safety protection and rapid and flexible deployment.

[0004] Therefore, designing a buffer structure that is effective, reusable, and multidimensionally extensible is a meaningful endeavor. It is of great value in improving material and space utilization, responding quickly and efficiently to emergencies, and reducing loss of life and property. Summary of the Invention

[0005] This invention aims to address the problems of insufficient buffering capacity and low reusability in existing buffer structures. This invention provides a force-magnetic coupling shock-resistant buffer unit and structure that offers excellent buffering performance, is reusable, and can be extended in multiple dimensions.

[0006] To achieve the above-mentioned objectives, the technical solution adopted is as follows:

[0007] The first aspect of the present invention provides a force-magnetic coupling shock-absorbing unit, comprising an elastic sphere, a spring, and a magnet; the elastic sphere is connected by the spring and the magnet, the elastic spheres are connected by the springs, all the springs are in the same straight line, the magnet passes through the interior of the elastic sphere and the spring, and the N pole or S pole of the magnet extending from the interior of the elastic sphere is connected to the S pole or N pole of the magnet extending from the interior of the adjacent elastic sphere.

[0008] In a preferred embodiment, in the above-mentioned force-magnetic coupling shock-absorbing unit, the magnet penetrates the interior of an elastic sphere, the center of the magnet is located at the center of the elastic sphere, and the length of the magnet is slightly longer than the diameter of the elastic sphere.

[0009] In a preferred embodiment, the elastic sphere in the above-mentioned force-magnetic coupling shock-absorbing unit is provided with a cylindrical through hole, and the edge of the cylindrical through hole is rounded.

[0010] In a preferred embodiment, in the above-mentioned force-magnetic coupling shock-resistant buffer unit, the diameter of the cylindrical through hole of the elastic sphere matches the cross-sectional diameter of the magnet.

[0011] In a preferred embodiment, the elastic sphere in the above-mentioned force-magnetic coupling shock-absorbing unit is made of elastic rubber material.

[0012] The selected materials are elastic rubber materials with high elastic modulus and high coefficient of friction, such as TPU.

[0013] In a preferred embodiment, the magnet in the above-mentioned force-magnetic coupling shock-absorbing unit is a slender, strong magnetic magnet with a circular cross-section. Each magnet penetrates the interior of a sphere, with its center located at the center of the sphere, and its length slightly longer than the diameter of the sphere. The magnetic attraction effectively limits the movement of adjacent spheres in a single sphere string model, dissipating impact energy.

[0014] In a preferred embodiment, the spring in the above-mentioned force-magnetic coupling shock-absorbing unit is a slender, rigid spring with a circular cross-section. Using a slender, rigid spring with a spherical structure connected to each end of the spring effectively limits the movement of adjacent spheres in a single sphere string model, thus dissipating impact energy.

[0015] The first aspect of the present invention provides a reusable force-magnetic coupling shock-absorbing structure, which is assembled discretely from multiple identical force-magnetic coupling shock-absorbing units and arranged in a staggered, layered manner to form a multi-row, multi-column combined structure.

[0016] In a preferred embodiment, in the above-mentioned force-magnetic coupling shock-resistant buffer structure, the force-magnetic coupling shock-resistant buffer units in the same layer are arranged in parallel arrays with equal spacing, and the force-magnetic coupling shock-resistant buffer units in adjacent layers are arranged orthogonally.

[0017] In a preferred embodiment, in the above-mentioned force-magnetic coupling shock-absorbing structure, the spring of each layer of force-magnetic coupling shock-absorbing unit is tangent to the spring of the next layer of force-magnetic coupling shock-absorbing unit, and the elastic sphere of each layer of force-magnetic coupling shock-absorbing unit is located in the gravitational potential hydradium formed by the four adjacent elastic spheres of the next two layers.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The reusable force-magnetic coupling shock-absorbing structure of this invention utilizes elastic spheres, which offer significant advantages: 1. They are easy to manufacture and have low cost. 2. They are isotropic, enabling omnidirectional energy absorption without the need to predict the load direction. 3. As a flexible structure, the sphere has high energy absorption efficiency. 4. The sphere has a large specific surface area, which helps to increase the energy consumed by friction and vibration.

[0020] In the reusable force-magnetic coupling shock-absorbing structure of this invention, the elastic spheres are connected by springs. Firstly, this topological connection forms a potential well, increasing the total energy absorption. Secondly, it achieves omnidirectional self-locking without external constraints. Thirdly, this modular design facilitates control and assembly in engineering. Furthermore, it possesses superior porosity, making it easier to implement energy dissipation mechanisms.

[0021] In the reusable force-magnetic coupling shock-resistant buffer structure of the present invention, the magnet structure is a durable magnet, and the elastic sphere structure is made of rubber. Therefore, the buffer structure has a large elastic deformation range and is not prone to plastic deformation that is difficult to restore to its original shape. After a force is buffered, most of the structure can still be reused. If there is a damaged part, the unit can be replaced separately to continue using the entire buffer structure. Therefore, the reusability of the entire buffer structure is greatly improved and the maintenance cost is greatly reduced.

[0022] The reusable force-magnetic coupling shock-resistant buffer structure of the present invention has the performance of easy assembly in a short time. When encountering some emergency situations, the small unit can be transported and quickly assembled to complete the shock-resistant task.

[0023] The reusable force-magnetic coupling shock-absorbing structure of the present invention contains a large number of springs and magnets, all of which are elastically deformable mechanisms. After buffering external forces, the overall structure will deform, but most of the springs that have not exceeded their elastic limits will return to their original length after buffering, thus having the characteristic of being reusable.

[0024] In other words, the reusable force-magnetic coupling shock-absorbing structure of this invention can more effectively buffer forces, reduce the impact of forces, and achieve efficient reuse, reducing maintenance and replacement costs and saving manpower and resources. This invention, through the combination of multiple energy absorption mechanisms, can effectively absorb energy from high-speed impacts. Attached Figure Description

Therefore, they should not be construed as limiting this invention.

[0038] The following is in conjunction with the appendix Figures 1 to 9 The present invention will be described in further detail below.

[0039] Example 1

[0040] refer to Figure 3 This invention provides a schematic diagram of a force-magnetic coupling shock-absorbing unit. It consists of an elastic sphere 1, a spring 4, and a magnet 3. The elastic spheres 1 are connected to each other via springs 4, and all springs 4 are aligned in a straight line. Simultaneously, the magnet 3 penetrates the interior of the elastic spheres 1 and springs 4. The N or S pole of the magnet extending from the interior of the elastic sphere 1 connects to the S or N pole of the magnet extending from the interior of the adjacent elastic sphere 1.

[0041] refer to Figure 5 The image shows a perspective view of a single elastic sphere structure, which is the basic small sphere unit that makes up the force-magnetic coupling anti-impact buffer unit of this invention. It is modeled using SolidWorks software. First, a sphere with a radius of 11.5 mm is designed. Then, a cylinder with a radius of 4.5 mm is removed from the center of the sphere. Next, a rounded corner with a radius of 1 mm is drawn from the edge of the through hole in the cylinder. Finally, it is 3D modeled from TPU material with high elasticity and a high coefficient of friction.

[0042] Figure 6 It is a single magnet structure, a cylindrical magnet with a diameter of 6mm and a length of 30mm, possessing significant magnetism. The magnetism at its N and S poles is much stronger than that in the middle of the cylinder. Its 6mm diameter fits perfectly with an 8mm diameter spring. The strong magnetic field generated at both ends ensures that the magnet 3 does not detach from the spring 4. Furthermore, the magnet 3 has rounded corners with a radius of 0.4mm at both ends, facilitating the connection of the magnet 3 and its manual separation in the absence of buffering.

[0043] Figure 7 This is a perspective view of a single spring structure used to connect the elastic sphere 1 and the magnet 3. It is a tightly wound spring with an average diameter of 8mm, a length of 30mm, and a total of 50 coils. The radius of the spring wire is 0.3m. The cylindrical through-hole of the elastic sphere has a diameter of 9mm, which allows the combination of spring 4 and magnet 3 to fit perfectly into the cylindrical through-hole 2 of the elastic sphere 1. Additionally, the 1mm gap compared to spring 4 is just enough to fill with adhesive or other binding materials.

[0044] The elastic sphere 1 of each force-magnetic coupling shock-absorbing unit is connected to form a whole by a spring 4 with the same diameter as the magnet in the magnet 3.

[0045] Example 2

[0046] refer to Figure 4 It is a single-layer structure consisting of three "individual discrete force-magnetic coupling shock-resistant buffer units".

[0047] refer to Figure 2 This embodiment is a four-layer assembled force-magnetic coupling shock-resistant buffer unit structure. Figure 2 It is by Figure 4 The single-layer structure shown is composed of four stacked layers. The force-magnetic coupling shock-resistant buffer units in the same layer are arranged in parallel arrays with equal spacing, and the force-magnetic coupling shock-resistant buffer units in adjacent layers are arranged orthogonally. The spring structure of each layer of force-magnetic coupling shock-resistant buffer unit is tangent to the spring structure of the next layer of force-magnetic coupling shock-resistant buffer unit. The spherical structure of each layer of force-magnetic coupling shock-resistant buffer unit is located in the gravitational potential hydrazine formed by the four adjacent spheres in the next two layers.

[0048] refer to Figure 8 This is an isometric view of the deformation that occurs during an external impact in this embodiment. As shown in the figure, during the impact, the spring is stretched and stores elastic potential energy due to the impact force; the magnets 3 inside the spring 4 also separate from each other to dissipate some energy through magnetic force; the elastic spheres 1 also dissipate the energy applied by the impact through elastic energy absorption and friction energy absorption due to mutual compression and friction.

[0049] Example 3

[0050] refer to Figure 1 This embodiment is an eight-layer assembled force-magnetic coupling shock-resistant buffer unit structure. Figure 1 It is by Figure 4 The single-layer structure shown is composed of eight stacked layers. The force-magnetic coupling shock-resistant buffer units in the same layer are arranged in parallel arrays with equal spacing, and the force-magnetic coupling shock-resistant buffer units in adjacent layers are arranged orthogonally. The spring structure of each layer of force-magnetic coupling shock-resistant buffer unit is tangent to the spring structure of the next layer of force-magnetic coupling shock-resistant buffer unit. The spherical structure of each layer of force-magnetic coupling shock-resistant buffer unit is located in the gravitational potential hydrazine formed by the four adjacent spheres in the next two layers.

[0051] refer to Figure 9This is a front view of the deformation diagram that occurs during the external impact process in this embodiment. As shown in the figure, during the external impact process, the spring will be stretched and store elastic potential energy due to the impact; the magnets 3 inside the spring 4 will also separate from each other to consume the impact energy through magnetic force; the elastic spheres 1 will also consume the energy applied by the impact through elastic energy absorption and friction energy absorption by squeezing and rubbing against each other.

[0052] In summary, the force-magnetic coupling shock-absorbing buffer structure of this invention is formed by horizontally orthogonally stacking single-layer structures of force-magnetic coupling shock-absorbing buffer units. If a single discrete force-magnetic coupling shock-absorbing buffer unit in this single-layer structure is damaged, it is not necessary to replace the entire single-layer structure; only the damaged discrete force-magnetic coupling shock-absorbing buffer unit needs to be replaced, and the overall force-magnetic coupling shock-absorbing buffer structure can function again. Therefore, this invention has the properties of reusability and the ability to replace parts of the structure, which greatly reduces its maintenance costs.

[0053] Because the same structure in each layer of the force-magnetic coupling shock-resistant buffer structure of this invention is formed by arranging the same units at certain intervals; then the different layers of structures are stacked so that the springs and magnets of each layer are perpendicular to the horizontal plane, and the elastic spheres clamp each other to form a stable stacked model.

[0054] In the force-magnetic coupling shock-absorbing structure of this invention, the force is buffered through three pathways:

[0055] 1. The elastic sphere structure uses a rubber ball with a high coefficient of friction. When the external pressure is applied during cushioning, the surface friction can offset part of the external force, thus achieving a cushioning effect.

[0056] 2. The spring structure uses a spring with a large elastic coefficient. When the multi-layer structure is compressed against each other, the spring will deform in the same direction as the force and generate an elastic force in the opposite direction to the force, thereby offsetting part of the external force and achieving a buffering effect.

[0057] 3. The magnetic structure uses the force generated when the magnets separate to counteract external forces, thus achieving a buffering effect.

[0058] Because of the spring clamping, the magnets are restricted by the spring after being separated under the action of force, so they will not bounce away randomly. After the external force buffering ends, there is a possibility of automatic reconnection.

[0059] In the force-magnetic coupling shock-absorbing structure of this invention, because the magnet structure uses a magnet with strong and durable magnetism and the elastic sphere structure uses a rubber ball, the overall force-magnetic coupling shock-absorbing structure has a large elastic deformation range and is not prone to plastic deformation that is difficult to restore to its original shape. After a force is buffered, most of the structure can still be reused. If there are damaged parts, the force-magnetic coupling shock-absorbing unit can be replaced individually to continue using the entire force-magnetic coupling shock-absorbing structure. Therefore, the reusability of the entire force-magnetic coupling shock-absorbing structure is greatly improved and the maintenance cost is greatly reduced.

[0060] When there is a strong impact from the outside, the external impact is applied to the outermost layer and then continues to apply pressure inward. The friction between the rubber balls, the deformation of the spring, and the separation of the magnet all buffer the force. As more and more parts participate in the buffering, the buffering effect becomes stronger and stronger. The external force is gradually buffered away, the spring gradually returns to its original shape, and the rubber balls begin to reduce the friction between them until the external force disappears completely.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. It is understood that those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
