[0003] The electromagnetic eddy current energy dissipation structure adopts the principle of electromagnetic induction. Based on Lenz's law, that is, the magnetic field of the induced current always hinders the change of the magnetic flux that causes the induced current, the induced eddy current converts the kinetic energy of the structure into electrical energy and further into thermal energy, thereby achieving energy dissipation. The performance of the electromagnetic eddy current energy dissipation structure / device is closely related to the material's electrical conductivity, magnetic saturation strength and other characteristics. Its design needs to consider factors such as magnetic field distribution and eddy current path to achieve efficient energy dissipation. At present, most eddy current energy dissipation structures are single-plate type and conventional double-plate type. The structure has problems such as low energy consumption efficiency. Therefore, it is necessary to optimize the material selection and structure to balance the relationship between material properties and losses.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figure 1 The present invention provides a space topology high-efficiency electromagnetic eddy current energy dissipation structure, which is used to solve the problems of low magnet utilization and insufficient damping force in the existing electromagnetic eddy current energy dissipation technology. The space topology high-efficiency electromagnetic eddy current energy dissipation structure of the present invention includes a magnet and a damping plate, and the damping plate includes a first plate body and a second plate body that are interlocked with each other, and a portion of the surface of the first plate body is exposed on the surface of the second plate body, so that the first plate body can strengthen the damping force that hinders the movement of the magnet and improve the magnet utilization. The space topology high-efficiency electromagnetic eddy current energy dissipation structure of the present invention is described below in conjunction with the accompanying drawings.

[0025] See also Figure 1 , showing the schematic diagram of the structure of the first embodiment of the space topology high-efficiency electromagnetic eddy current energy dissipation structure. Figure 1 , the spatial topology efficient electromagnetic eddy current energy dissipation structure of the present invention is explained.

[0026] like Figure 1 As shown, the spatial topological high-efficiency electromagnetic eddy current energy dissipation structure of the present invention includes a magnet 21 and a damping plate arranged below or above the magnet 21, the damping plate includes a first plate body 22 and a second plate body 23 stacked up and down, the first plate body 22 is provided with a first embedding portion 221, the second plate body 23 is provided with a second embedding portion 231, the first embedding portion 221 and the second embedding portion 231 can be embedded with each other so that a part of the first plate body 22 is located on the surface of the second plate body 23 away from the first plate body 22.

[0027] The damping plate is arranged above or below the magnet 21, and a gap is left between the damping plate and the magnet 21, and the two are arranged in a non-contact manner. The size of the gap can be determined by conversion based on the magnetic force of the magnet, and the gap is usually set to be less than 1 mm. The magnet 21 can be connected to the structure that needs vibration reduction, and then reciprocate under the vibration of the structure that needs vibration reduction. The magnet 21 can reciprocate along a certain direction relative to the damping plate, for example Figure 1 In the F direction, Figure 1 In the first embodiment shown, the magnet 21 can reciprocate relative to the damping plate along the F direction. When the magnet 21 reciprocates relative to the damping plate, the magnetic flux lines of the magnet cut the second plate body, generating an induced current in the second plate body. Through Lenz's law, the first plate body can strengthen the damping force that hinders the movement of the magnet. Specifically, according to the characteristics of the electromagnet, the magnetic force generated by the electromagnet with an iron core will be greater than the magnetic force generated by the electromagnet without an iron core. Therefore, the part of the first plate body located on the surface of the second plate body is equivalent to the iron core in the electromagnet, which will strengthen the magnetic field generated by the eddy current of the same size in the second plate body, consume high energy, and thus more effectively hinder the movement of the magnet.

[0028] Furthermore, due to the structural form of the damping plate of the present invention, the damping force that hinders the movement of the magnet is strengthened, and the spatial topological high-efficiency electromagnetic eddy current energy dissipation structure of the present invention can greatly reduce the space volume occupied by the electromagnetic damping structure.

[0029] In the first embodiment of the present invention, Figure 1 As shown, the first interlocking portion 221 is a plurality of protrusions provided on the first plate body 22; the second interlocking portion 231 is a plurality of through channels provided on the second plate body 23, and the through channels are adapted to the protrusions; the through channels on the second plate body 23 pass through the upper and lower surfaces of the second plate body 23, wherein the surface of the second plate body 23 that is in contact with the first plate body 22 is the lower surface, and the surface away from the first plate body 22 is the upper surface, so that the second plate body 23 is a hollow plate; when the first plate body 22 and the second plate body 23 are stacked up and down, the protrusions can be inserted into the corresponding through channels, and then the top surface of the protrusions is located on the surface of the second plate body 23 away from the first plate body 22.

[0030] Furthermore, the outer contours of the protrusions and the through-channels are circular, but the outer contours of the protrusions and the through-channels are not limited to circular, and may also be other shapes such as squares and rectangles, or may be irregular geometric shapes such as special shapes.

[0031] In a second embodiment of the present invention, Figure 2 As shown, the first engaging portion 221 is a plurality of grooves provided on the first plate body, and the grooves are arranged in a staggered manner in the horizontal and vertical directions; the second engaging portion 231 is a plurality of slats forming the second plate body 23, and the slats are arranged in a staggered manner in the horizontal and vertical directions, and the slats are adapted to the grooves; when the first plate body 22 and the second plate body 23 are stacked up and down, the slats can be embedded in the corresponding grooves, and thus the surface of the first plate body 22 except the grooves is located on the surface of the second plate body 23 away from the first plate body 22.

[0032] Further, the second plate 23 is a grid plate, and the upper surface of the first plate 22 is provided with grid-shaped grooves, so that the second plate 23 can be completely embedded in the grid-shaped grooves of the first plate 22. The thickness of the strips of the second plate 23 is consistent with the depth of the grooves.

[0033] In a specific embodiment of the present invention, the first plate body 22 is made of ferromagnetic material, such as silicon steel, and the second plate body 23 is a metal plate with good electrical conductivity.

[0034] Furthermore, the first plate body 22 may be a magnetically conductive plate, and the second plate body 23 may be a copper plate.

[0035] Copper is a precious metal. The structural design of the first embodiment and the second embodiment of the present invention can greatly reduce the amount of copper used, which can bring good economic benefits. The first plate body 22 of the present invention is not limited to a magnetic plate, and it can also be other magnetic metal plates, such as alloy plates, Permalloy plates, etc. The second plate body 23 of the present invention is also not limited to a copper plate, and it can also be other precious metal plates, such as a gold plate, a silver plate, etc.

[0036] Furthermore, the outer contours of the first plate body 22 and the second plate body 23 are square or rectangular. The outer contours of the first plate body 22 and the second plate body 23 have the same size.

[0037] Furthermore, the size of the magnet 21 is smaller than the size of the first plate 22 and the second plate 23 , and the magnet 21 can reciprocate relative to the first plate 22 and the second plate 23 .

[0038] Furthermore, the second plate 23 is disposed close to the magnet 21 .

[0039] In a specific embodiment of the present invention, the magnet 21 is a magnet block or a magnet block array.

[0040] The magnet block can be a permanent magnet block or an electromagnet block. The shape of the magnet 21 is not limited, and can be square, rectangular, circular, etc., or other shapes.

[0041] The magnet block array may include multiple permanent magnet blocks, multiple electromagnet blocks, or a combination of multiple permanent magnet blocks and multiple electromagnet blocks. When arrayed, the magnetic poles of adjacent magnet blocks are arranged in opposite and staggered patterns, or may be arranged in other ways. Preferably, a frame structure is provided, and the magnet blocks are embedded in the frame structure, thereby forming a magnet block array structure.

[0042] If the magnet is a permanent magnet block, the magnetic field strength is fixed, and the corresponding size and / or number of permanent magnet blocks can be selected according to the design requirements.

[0043] If the magnet adopts an electromagnet block, including the form of using an electromagnet block alone or using an electromagnet block and a permanent magnet block in combination, the magnetic field strength can be changed. In this way, the magnet using the electromagnet block can intelligently adjust the damping force according to the needs of the actual application scenario to obtain the best effect.

[0044] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
