[0002] In industries such as manufacturing and construction, there exist various large-scale machinery and equipment. These machines often generate significant vibrations during operation, which propagate through solid media. This can easily lead to long-term environmental vibrations and secondary structural noise from nearby buildings. This not only severely impacts the quality of life and work of nearby residents and the use of vibration-sensitive equipment, but also damages the structural strength of buildings, causing cracks in doors, windows, and walls. Furthermore, the vibrations themselves can damage equipment, shortening its lifespan.

Based on the principle of opposite repulsion of neodymium magnets, a non-contact suspension structure is designed to completely block the propagation path of solid vibration, reduce mechanical wear, reduce secondary noise generated by vibration, and extend service life. This invention addresses the issue of contact between the outer wall of the upper shell and the inner wall of the lower shell by using an outer repulsion member on the inner wall of the lower shell that corresponds one-to-one with an inner repulsion member on the outer wall of the upper shell. Furthermore, by utilizing the repulsive force between the first and second neodymium magnets on the sides, the invention prevents the outer wall of the upper shell from contacting the inner wall of the lower shell. Based on the principle of opposite repulsion of neodymium magnets, a contactless suspension structure is designed to completely block the propagation path of solid vibration, reduce mechanical wear, reduce secondary noise generated by vibration, and extend service life. This invention transmits vibrations from the lower outer shell to the helical cantilever beam, generates piezoelectric current through piezoelectric blocks, and then inputs electrical energy into the battery for storage through the current and voltage regulation of the upper and lower electrodes, rectifier and DC-DC converter, thereby realizing vibration energy recovery, improving system sustainability, and providing auxiliary power supply for the system.

At the same time, the buffer spring can also play a buffering role, protecting the lower neodymium magnet and preventing it from losing magnetism and being damaged due to expansion caused by impact. In this invention, the top plate is pressed down and moves downward, causing the two ends of the conductive rod to contact the two conductive sliders respectively, thereby connecting the circuit between the electromagnet and the battery. The electromagnet generates magnetic force and repulses the upper neodymium magnet, further buffering the equipment and protecting the lower neodymium magnet. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0018] Example 1, by Figures 1-4 The present invention relates to a magnetic vibration damper suitable for large-scale machinery and equipment, comprising a base 1, with a rubber pad installed at the lower end for fixing to the ground and further reducing vibration; a lower outer shell 2 fixedly installed at the top of the base 1, made of a non-magnetic and non-deformable rigid material, the lower outer shell 2 being cylindrical; an upper outer shell 3, also made of a non-magnetic and non-deformable rigid material, being cylindrical, with a rubber pad installed at the top to prevent direct contact between the magnetic vibration damper and the vibrating equipment, thus avoiding wear; and a magnetic vibration damping assembly 4 disposed between the lower outer shell 2 and the upper outer shell 3.
[0019] The magnetic vibration damping assembly 4 includes a lower neodymium magnet 401 fixedly installed on the inner bottom wall of the lower outer shell 2. A bottom energy trapping device 5 is provided below the lower neodymium magnet 401. A bottom mounting groove 402 is opened at the bottom end of the upper outer shell 3. An upper neodymium magnet 403 is installed inside the bottom mounting groove 402. The lower neodymium magnet 401 inside the lower outer shell 2 and the upper neodymium magnet 403 at the bottom of the upper outer shell 3 have a repulsive force. While supporting the equipment, it reduces vibration through magnetic force. Based on the principle of opposite repulsion of neodymium magnets, a non-contact suspension structure is designed to completely block the propagation path of solid vibration, reduce mechanical wear, and extend service life. A bottom cover plate 404 is provided below the upper neodymium magnet 403. It is made of a rigid material that is non-magnetic and not easily deformed and is used to fix the magnet at the bottom. The bottom cover plate 404 is bolted to the upper outer shell 3.
[0020] The diameter of the upper outer shell 3 is smaller than the inner diameter of the lower outer shell 2. Three inner repulsion members 405 are provided at equal angles on the upper outer shell 3, and three outer repulsion members 406 are provided at equal angles on the inner wall of the lower outer shell 2. The inner repulsion members 405 and the outer repulsion members 406 correspond one-to-one. A buffer protection component 6 is provided between the lower outer shell 2 and the upper outer shell 3. The inner repulsive component 405 includes a first side mounting groove 4051 that is equally angled on the side wall of the upper outer shell 3. A first side neodymium magnet 4052 is installed inside the first side mounting groove 4051. A first side cover plate 4053 is provided on the side of the first side neodymium magnet 4052 away from the axis of the upper outer shell 3. The cover plate is made of a rigid material that is non-magnetic and not easily deformed and is used to fix the magnet on the side. The first side cover plate 4053 is bolted to the upper outer shell 3. The outer wall of the first side cover plate 4053 is on the same arc surface as the circumferential outer wall of the upper outer shell 3.
[0021] The outer repulsive member 406 includes a second side mounting groove 4061 equally angled on the inner wall of the lower outer shell 2. A second side neodymium magnet 4062 is installed inside the second side mounting groove 4061. The two second side neodymium magnets 4062 are longitudinally distributed. A second side cover plate 4063, made of a non-magnetic and non-deformable rigid material, is provided on the side of the second side neodymium magnet 4062 near the inner cavity of the lower outer shell 2 to fix the side magnets. The second side cover plate 4063 is bolted to the lower outer shell 2, and the outer wall of the second side cover plate 4063 is flush with the inner wall of the inner cavity of the lower outer shell 2. On an arc surface, the outer repulsion member 406 provided on the inner wall of the lower outer shell 2 corresponds one-to-one with the inner repulsion member 405 provided on the outer wall of the upper outer shell 3. Through the repulsive force between the first side neodymium magnet 4052 and the second side neodymium magnet 4062, the outer wall of the upper outer shell 3 and the inner wall of the lower outer shell 2 are prevented from contacting each other. Furthermore, based on the principle of opposite repulsion of neodymium magnets, a non-contact suspension structure is designed to completely block the propagation path of solid vibration, reduce mechanical wear, and extend service life. In this way, the upper and lower shells can be kept coaxial and do not come into contact, thus achieving complete suspension.
[0022] Example 2, based on Example 1, is... Figures 5-7 The bottom energy harvesting device 5 includes a groove 501 formed on the base 1, located below the lower neodymium magnet 401. A helical cantilever beam 502 is arranged inside the groove 501, and piezoelectric blocks 503 are evenly installed on the helical cantilever beam 502. One end of the helical cantilever beam 502 is bolted to the inner wall of the groove 501, and a mass block is installed at the other end of the helical cantilever beam 502. The helical cantilever beam 502 is made of stainless steel. External vibrations, such as equipment operation and human movement, are transmitted to the cantilever beam 502. The inertia of the mass block drives the beam to bend, causing periodic deformation.
[0023] The piezoelectric block 503 is made of lead zirconate titanate film. The bending of the cantilever beam 502 compresses or stretches the lead zirconate titanate film, and the internal lattice displacement generates polarization charge, forming an alternating voltage between the two electrodes. The upper and lower surfaces of the piezoelectric block 503 are provided with metal-plated layers to form electrodes, which facilitates the collection of charge. A storage battery 504, a rectifier 505, and a DC-DC converter 506 are connected in series between the two electrodes. The vibration on the lower shell 2 is transmitted to the spiral cantilever beam 502 and generates piezoelectric current through the piezoelectric block 503. Then, through the current and voltage regulation of the upper and lower electrodes, the rectifier 505, and the DC-DC converter 506, the electrical energy is input into the storage battery 504 for storage, realizing the recovery of vibration energy.
[0024] Example 3, based on Example 2, by Figures 8-10 The buffer protection assembly 6 includes three pressure plates 601 that are equally spaced on the outside of the upper housing 3. A connecting frame 602 is fixedly installed on the top of the pressure plate 601 and fixedly installed on the outer wall of the upper housing 3. A middle support member 603 and a pressure-bearing electrical contact member 604 are provided below the pressure plate 601.
[0025] The central support member 603 includes three side slots 6031 that are equally angled on the inner wall of the lower outer shell 2. A support buffer module 6032 is movably installed inside the side slots 6031. The side slots 6031 are located above the lower neodymium magnet 401. A guide rod 6033 is installed on the side of the support buffer module 6032 away from the axis of the lower outer shell 2. One end of the guide rod 6033 extends to the outside of the lower outer shell 2. An end plate 6034 is fixedly installed on the end of the guide rod 6033 located outside the lower outer shell 2. Buffer springs 6035 are symmetrically installed on the side of the end plate 6034 near the outer wall of the lower outer shell 2. One end of the buffer spring 6035 is fixedly connected to the outer wall of the lower outer shell 2.
[0026] The support buffer module 6032 includes a support block 60321 located inside the side groove 6031. The support block 60321 has a receiving groove 60322 inside. An electromagnet 60323 is installed inside the receiving groove 60322. A top cover 60324 is provided above the electromagnet 60323. The top cover 60324 is bolted to the support block 60321, and the top wall of the top cover 60324 is flush with the top wall of the support block 60321.
[0027] The pressure-bearing electrical connection component 604 includes three fixed boxes 6041 mounted at equal angles to the top of the base 1. An inner plate 6042 is movably installed inside each fixed box 6041. Support rods 6043 are symmetrically mounted on the top of each inner plate 6042, extending through to the top of the fixed box 6041. A top plate 6044 is fixedly mounted on the top of each support rod 6043. The height of the top plate 6044 is higher than the height of the end plate 6034. The top plate 6044 is close to... A connecting rod 6045 is hinged to one side of the end plate 6034. One end of the connecting rod 6045 is hinged to the end plate 6034. When the equipment is subjected to a strong downward impact force, the upper outer shell 3 moves downward along the lower outer shell 2. When the bottom of the upper outer shell 3 approaches the lower neodymium magnet 401, the pressure plate 601 pushes the top plate 6044 downward, and the connecting rod 6045 pushes the support block 60321 between the upper outer shell 3 and the lower neodymium magnet 401, thus providing support, buffering and protection for the upper outer shell 3. Simultaneously, the buffer spring 6035 also serves as a buffer, protecting the lower neodymium magnet 401 from demagnetization and damage due to impact expansion. The top plate 6044 is located below the pressure plate 601. A conductive rod 6046 is fixedly installed on the inner plate 6042, with its two ends located on both sides of the inner plate 6042. Conductive sliders 6047 are symmetrically installed on the inner walls of both sides of the fixing box 6041. The conductive sliders 6047 are located... Below the internal plate 6042, an electromagnet 60323 and a battery 504 are connected in series between two conductive sliders 6047. When the top plate 6044 is pressed down, the two ends of the conductive rod 6046 contact the two conductive sliders 6047 respectively, thereby connecting the circuit between the electromagnet 60323 and the battery 504. The electromagnet 60323 generates magnetic force and repulses the upper neodymium magnet 403, further buffering the equipment and protecting the lower neodymium magnet 401.
[0028] Working principle: In use, the base 1 is bolted to the ground, and the upper outer shell 3 is installed at the bottom of the equipment. The upper outer shell 3 is located inside the lower outer shell 2, with the inner repulsive member 405 corresponding one-to-one with the outer repulsive member 406. The lower neodymium magnet 401 generates a repulsive force against the upper neodymium magnet 403, supporting the equipment and achieving vibration reduction through magnetic force. At the same time, three sets of inner repulsive members 405 are provided on the outer wall of the upper outer shell 3. The first side mounting groove 4051 includes a first side mounting groove. The first side neodymium magnet 4052 is installed in the groove 4051, and three sets of outer repulsion members 406 are provided on the inner wall of the lower outer shell 2. The outer repulsion members 406 include two second side neodymium magnets 4062 installed in the second side mounting groove 4061. The inner repulsion members 405 correspond one-to-one with the outer repulsion members 406. Through the repulsive force between the second side neodymium magnets 4062 and the first side neodymium magnets 4052, the outer wall of the upper outer shell 3 and the inner wall of the lower outer shell 2 are prevented from contacting and colliding. When vibration occurs, the spiral cantilever beam 502 vibrates continuously and exerts pressure on the piezoelectric block 503, causing the piezoelectric block 503 to generate piezoelectric current. This current is then converted from alternating current to direct current by the rectifier 505 through the upper and lower electrodes. After the voltage is adjusted by the DC-DC converter 506, the electrical energy is stored in the battery 504, thus realizing vibration energy recovery. When the device is subjected to a large downward impact force, the upper outer shell 3 moves downward along the lower outer shell 2. When the bottom of the upper outer shell 3 approaches the lower neodymium magnet 401, the pressure plate 601 on the circumference of the upper outer shell 3 contacts the top plate 6044 and pushes the top plate 6044 downward. Through the connecting rod 6045, the support block 60321 is pushed to move outward of the side groove 6031 between the upper outer shell 3 and the lower neodymium magnet 401. The elastic force of the buffer spring 6035 can buffer the downward impact force, while the support block 60321 can block the upper outer shell 3 and play a buffering role to prevent the lower neodymium magnet 401 from being damaged by violent collision. At the same time, after the top plate 6044 moves downward under the force, the two ends of the conductive rod 6046 contact the two conductive sliders 6047 respectively, so that the electrical energy stored in the battery 504 is output to the electromagnet 60323, so that the electromagnet 60323 is energized to generate magnetic force and generate repulsive force on the upper neodymium magnet 403, further slowing down the downward movement of the upper outer shell 3 and further protecting the equipment and the lower neodymium magnet 401.
