[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Magnetic levitation technology, as an important means of achieving contactless levitation of objects, is widely used in various precision instruments and devices. Traditional magnetic levitation devices typically use large ring magnets, achieving levitation through magnetic repulsion. However, this method, due to the large size and weight of the ring magnets, results in complex structures, high processing difficulty, and high manufacturing costs, hindering large-scale promotion and application. Specifically, traditional magnetic levitation technology is difficult to adapt to the needs of miniaturized levitation objects, such as levitation pens, as the size and arrangement of the magnets limit effective and stable levitation. The levitation of small levitation objects is constrained by the interaction forces between magnets and structural space, leading to complex overall device structures, high manufacturing costs, and difficulty in meeting the application requirements of miniaturization and low cost.

[0021] Based on this, see Figures 1 to 4 As shown, this utility model embodiment provides a magnetic levitation device 10, which includes a base assembly 100, a suspension structure 200, and a magnetic levitation component 300. The base assembly 100 has a suspension groove 111 at its top. One end of the suspension structure 200 is suspended in the suspension groove 111. The magnetic levitation component 300 includes a first magnet 310, a second magnet 320, and a third magnet 330. The first magnet 310 is arranged around the suspension groove 111. The second magnet 320 and the third magnet 330 are arranged on the suspension structure 200. The second magnet 320 is arranged around the outer periphery of the suspension structure 200 and is located outside the suspension groove 111. The third magnet 330 is coaxially arranged with the suspension structure 200 and is located inside the suspension groove 111. The second magnet 320 and the first magnet 310 repel each other, and the third magnet 330 and the first magnet 310 attract each other.

[0022] In the magnetic levitation device 10 of this embodiment, stable magnetic levitation of the suspension structure 200 is achieved by rationally arranging and coordinating the first magnet 310, the second magnet 320, and the third magnet 330. Specifically, the first magnet 310 is arranged around the suspension groove 111, the second magnet 320 is arranged around the outer periphery of the suspension structure 200 and located outside the suspension groove 111, and the third magnet 330 is coaxially arranged inside the suspension structure 200 and located inside the suspension groove 111. The mutual repulsion between the first magnet 310 and the second magnet 320 provides a stable levitation support force, ensuring that the suspension structure 200 can be vertically suspended in the suspension groove 111; at the same time, the attraction between the first magnet 310 and the third magnet 330 effectively prevents the suspension structure 200 from shifting or detaching from the suspension groove 111 due to magnetic imbalance.

[0023] This embodiment achieves a compact and simplified device structure by coordinating the magnetic forces through a combination of multiple magnets. This structural design not only reduces the overall size and weight of the levitation device but also decreases processing difficulty and manufacturing costs, making it suitable for small levitation objects such as levitation pens. Simultaneously, the use of a surround and coaxial magnet layout optimizes the magnetic field distribution, improving levitation stability and accuracy, and solving the problem of insufficient levitation stability caused by limitations in magnet size and arrangement in traditional technologies.

[0024] Furthermore, the base assembly 100 includes a base body 110 and a shielding cover 120. A levitation channel 111 is disposed on the top of the base body 110, and a first magnet 310 is disposed inside the base body 110. The shielding cover 120 covers the side of the first magnet 310 away from the levitation channel 111. This structural layout helps to effectively control and optimize the magnetic field distribution of the first magnet 310, enhancing the overall magnetic effect of the magnetic levitation device 10.

[0025] Specifically, the first magnet 310, as a magnet surrounding the suspension trough 111, has a magnetic field that exhibits a certain directionality in space. Since the magnetic field lines of the magnet are closed, the magnetic field of the first magnet 310 will diffuse along its ends and periphery. Without the shielding cover 120, the magnetic force of the first magnet 310 may diffuse in multiple directions, causing some magnetic force to be lost or dispersed, reducing the effective force exerted on the second magnet 320 and the third magnet 330, and consequently affecting the suspension stability and load-bearing capacity of the suspension structure 200.

[0026] The shield 120 is located on the side of the first magnet 310 away from the suspension trough 111, and is mainly made of high magnetic permeability materials, such as soft iron, silicon steel sheets, or nickel-iron alloys. The presence of the shield 120 can guide and concentrate the magnetic field lines of the first magnet 310, preventing the magnetic force from diffusing in the direction of the shield 120, thereby enhancing the magnetic field strength of the first magnet 310 towards the second magnet 320. This enhanced magnetic field force increases the repulsive force between the first magnet 310 and the second magnet 320, improving the stable support force of the suspension structure 200.

[0027] Furthermore, the shielding cover 120 reduces interference from the magnetic field to other surrounding electronic devices or magnetic components, prevents magnetic field leakage from affecting the external environment, and improves the electromagnetic compatibility and safety of the device. The material thickness and shape of the shielding cover 120 can be optimized according to the actual size of the magnet and the magnetic field strength. For example, the thickness can be 0.5 mm, 1 mm, or 1.5 mm, and the shape can be designed as a ring or a cover structure to match the shape of the first magnet 310, ensuring the magnetic field shielding and guiding effect.

[0028] In summary, the shield 120 in the base assembly 100 effectively guides and concentrates the magnetic force of the first magnet 310, ensuring that the magnetic force of the first magnet 310 towards the second magnet 320 is greater, thereby enhancing the suspension support force and overall stability of the magnetic levitation device, and helping to reduce external magnetic field interference, thus improving the practicality and safety of the device.

[0029] In one embodiment, the levitation structure 200 includes a connecting base 223 and a plurality of mounting members 224. The mounting members 224 are detachably connected to the connecting base 223, and the plurality of mounting members 224 are evenly arranged along the outer periphery of the connecting base 223. A second magnet 320 is disposed on the mounting member 224, and a third magnet 330 is disposed within the connecting base 223. Through this structural design, the mounting member 224 not only achieves a stable installation of the second magnet 320, but also provides effective fixed support for the third magnet 330, keeping its position stable relative to the connecting base 223. This ensures that the third magnet 330 is located on the circumferential outer side of the levitation structure 200, facilitating the formation of the expected magnetic attraction force with the first magnet 310, thereby improving the stability of the levitation structure 200.

[0030] Specifically, the multiple mounting components 224 allow the third magnet 330 to be distributed at different positions on the connector 223, avoiding the problem of uneven magnetic field caused by concentrated magnets and promoting uniform magnetic field distribution and magnetic force balance. The detachable connection method between the mounting components 224 and the connector 223 facilitates the maintenance, replacement, and adjustment of the magnets, improving the maintainability and flexibility of the device. The mounting components 224 can be made of lightweight materials with a certain degree of rigidity, such as engineering plastics or aluminum alloys, to ensure the lightweight and structural strength of the overall levitation structure 200.

[0031] In this embodiment, there are three sets of mounting components 224 and third magnets 330, and the three sets are evenly arranged along the circumference of the connecting base 223. The even distribution of the three sets can form a symmetrical magnetic field layout, so that the attractive force generated by the third magnet 330 acts evenly on all directions of the suspension structure 200, which helps to prevent the suspension structure 200 from swaying or rotating unstablely, and improves the stability and reliability of the suspension device.

[0032] In other embodiments, the number of mounting components 224 and third magnets 330 can also be four, five, or more, depending on factors such as the size of the levitation structure 200, load requirements, and magnet performance. For example, when four groups are evenly distributed, the magnetic field distribution of the levitation structure 200 is more uniform, and the stability of the levitation body may be further improved; setting more groups allows for more precise adjustment of the magnetic field layout, which is suitable for occasions with higher requirements for levitation accuracy.

[0033] Specifically, the outer wall of the connector 223 is provided with multiple snap-fit ​​parts 2231, and the mounting part 224 is detachably connected to the snap-fit ​​parts 2231. This structural design achieves reliable fixation between the mounting part 224 and the connector 223 through the snap-fit ​​parts 2231, while also providing easy assembly and disassembly.

[0034] Specifically, the snap-fit ​​part 2231 can be designed in various forms such as a slot, hook, elastic latch, or concave-convex interlocking structure. The material can be engineering plastics, metals, or composite materials with a certain degree of elasticity and strength. The snap-fit ​​structure enables the quick installation and removal of the mounting part 224 without the need for complex fasteners such as screws or rivets, thereby simplifying the assembly process and improving production efficiency.

[0035] The mating dimensions between the snap-fit ​​part 2231 and the mounting part 224 can be designed according to actual needs. For example, the width, depth, and elastic deformation of the snap-fit ​​part 2231 can be set to 1 mm, 2 mm, 3 mm, or larger values, respectively. The structural dimensions of the mounting part 224 should match those of the snap-fit ​​part 2231 to ensure the firmness of the snap-fit ​​and the ease of disassembly. If the size of the snap-fit ​​part 2231 is too small, the mounting part 224 may not be able to snap in smoothly or may be unstable, affecting the stability of the suspension structure 200. If the size is too large, there may be a gap between the snap-fit ​​part and the mounting part, reducing the fixing strength and causing the mounting part 224 to loosen or fall off.

[0036] The use of a snap-fit ​​connector 2231 to connect with the mounting component 224 effectively reduces fastener damage caused by frequent disassembly and assembly, thereby improving the service life and maintenance convenience of the levitation structure 200. Furthermore, this structure facilitates the replacement or adjustment of the mounting component 224 and the third magnet 330, meeting the adjustment requirements for the magnetic field distribution and magnet position of the levitation structure 200 in different application scenarios.

[0037] In one embodiment, the mounting component 224 includes a mounting tube 2242 and a fixing part 2241. The mounting tube 2242 has a mounting cavity 22421 inside. The fixing part 2241 is inserted into the mounting cavity 22421. The second magnet 320 is disposed within the mounting cavity 22421, and the end of the fixing part 2241 abuts against the second magnet 320. This structural design helps to achieve stable installation and positioning of the second magnet 320, ensuring that the magnet is in a predetermined position within the levitation structure 200, and preventing displacement of the magnet due to external forces or vibrations, thereby affecting the magnetic field distribution and levitation performance.

[0038] During assembly, the second magnet 320 is first inserted into the mounting cavity 22421 of the mounting tube 2242. The second magnet 320 and the inner wall of the mounting cavity 22421 form a tight fit, which can restrict the radial movement of the magnet to a certain extent. Then, the fixing part 2241 is inserted into the rear side of the second magnet 320, so that the end of the fixing part 2241 abuts against one end face of the second magnet 320. Axial constraint on the second magnet 320 is achieved through a plug-in connection. The plug-in connection between the fixing part 2241 and the mounting cavity 22421 can adopt various forms such as interference fit, snap-fit ​​structure, or threaded connection. The specific connection method can be selected according to the actual manufacturing process and assembly requirements.

[0039] The fixing part 2241 can be made of engineering plastics, aluminum alloys, or stainless steel with a certain degree of elasticity and strength to ensure that the fixing part 2241 can be firmly fixed during the insertion process while being easy to disassemble, meeting the needs of maintenance and replacement. The end shape of the fixing part 2241 can be designed as a flat surface, a stepped surface, or a slightly elastically deformable bayonet structure to enhance the resisting effect on the second magnet 320 and prevent the magnet from loosening during long-term use.

[0040] With the cooperation of the mounting tube 2242 and the fixing part 2241, the second magnet 320 can be effectively fixed in the radial and axial directions, ensuring that the installation position of the magnet is accurate and stable. This helps to achieve a uniform distribution of the magnetic field and a stable output of the levitation force in the magnetic levitation device, further improving the overall performance and reliability of the levitation structure 200.

[0041] Furthermore, the structure is easy to assemble and disassemble; the second magnet 320 can be quickly removed after disassembling the fixing part 2241, facilitating maintenance, replacement, or adjustment of the magnet's position and improving the maintainability and application flexibility of the device. The structural dimensions and shape of the fixing part 2241 and the mounting tube 2242 can be customized according to the specific dimensions of the second magnet 320 to accommodate magnets of different specifications.

[0042] Specifically, the base assembly 100 has a top 112 coaxial with the suspension trough 111, and the suspension structure 200 includes a support portion 222, with a support groove 2221 formed on the side of the support portion 222 facing the top 112. The support portion 222 is suspended within the suspension trough 111, and the top 112 is at least partially housed within the support groove 2221 and contacts the end face of the support groove 2221. This structure achieves mechanical positioning and support between the suspension structure 200 and the base assembly 100, ensuring the stability of their relative positions and contributing to the overall compact structure and stable movement of the magnetic levitation system.

[0043] Specifically, the inner end face of the support groove 2221 can be designed as an arc shape. This arc design can increase the contact area while reducing the local stress on the contact surface and reducing the coefficient of friction, thereby slowing down the wear between the support part 222 and the abutment 112 and extending the service life of the device. The arc surface can also play a certain self-adjusting role, enabling the support part 222 to roll rather than slide when subjected to small displacements, reducing frictional resistance and improving the response sensitivity and dynamic stability of the suspension structure 200.

[0044] The top abutment 112 can adopt a conical structure design. The conical structure can effectively reduce the contact area between the top abutment 112 and the end face of the support groove 2221, thereby reducing the frictional resistance of the contact surface. The conical structure makes the contact between the top abutment 112 and the support groove 2221 mainly concentrated in one or a few points or lines, which helps to reduce mechanical jamming and facilitates the free micro-movement and adaptive adjustment of the suspension structure 200 under the action of magnetic force, which is beneficial to improving the dynamic performance and stability of the suspension device.

[0045] The compact combination of the top 112 and the support groove 2221 helps to reduce the spatial distance between the suspension structure 200 and the base assembly 100, thereby reducing the size and weight of the mechanical structure and meeting the design requirements of miniaturized suspension devices. This structural design facilitates high-precision mechanical alignment and positioning, ensuring stable suspension and motion control of the suspension structure 200.

[0046] Furthermore, the support portion 222 and the abutment portion 112 can be made of materials with low coefficient of friction and wear resistance, such as engineering plastics like polytetrafluoroethylene (PTFE) and nylon, or metals with hardened surfaces like aluminum alloys and stainless steel. This material selection can further reduce frictional loss and improve structural durability.

[0047] In one embodiment, the support portion 222 has a mounting groove 2222 inside, and the third magnet 330 is housed in the mounting groove 2222. The mounting groove 2222, through its structural shape and size design, realizes the positioning function of the third magnet 330, ensuring the accurate position and stable state of the third magnet 330 inside the support portion 222.

[0048] Specifically, the dimensions of the mounting groove 2222 should match the external dimensions of the third magnet 330, and the fitting clearance can be controlled between 0.05 mm and 0.5 mm, such as 0.05 mm, 0.1 mm, 0.3 mm, 0.5 mm, etc., to ensure that the third magnet 330 can be installed smoothly, and to effectively limit its radial and axial movement in the mounting groove 2222, so as to prevent the magnet from deviating and causing abnormal magnetic field distribution or decreased levitation performance.

[0049] The mounting groove 2222 can be rectangular, semi-circular, recessed, or other groove-shaped structures suitable for the shape of the third magnet 330 to achieve tight containment and effective protection. The inner surface of the mounting groove 2222 can be smoothed or coated with a wear-resistant coating to reduce friction between the third magnet 330 and the support 222, reduce wear during installation and disassembly, and extend the service life of the device.

[0050] After the third magnet 330 is housed in the mounting groove 2222, the mounting groove 2222 provides mechanical protection for it, preventing the third magnet 330 from being directly affected by external impacts, vibrations or other mechanical loads, reducing the risk of magnet damage or displacement, and improving the reliability and stability of the magnetic levitation structure.

[0051] The mounting slot 2222 can be made of engineering plastics, aluminum alloys, or composite materials with a certain degree of rigidity and wear resistance to meet the requirements of mechanical strength and durability. If further protection is required, cushioning materials or pads, such as silicone gaskets or elastomer pads, can be placed inside the mounting slot 2222 to absorb vibration and impact, reduce direct collision between the magnet and the support, and improve the durability and service life of the device.

[0052] In one specific embodiment, the suspension structure 200 is a rod-shaped structure that extends along its axial direction to form an integral shape, facilitating linear suspension and stable support. When the suspension structure 200 is suspended within the base assembly 100, the suspension structure 200 is coaxially arranged with the first magnet 310, that is, the magnetic axis of the first magnet 310 coincides with or substantially coincides with the axis of the rod-shaped suspension structure 200.

[0053] This coaxial arrangement helps ensure the symmetry and uniformity of the magnetic field distribution, reducing the torque and eccentric force caused by magnetic field inhomogeneity, thereby improving the stability and smoothness of the levitation structure 200. Specifically, the first magnet 310 is arranged along the axial direction of the levitation structure 200, and its magnetic field center coincides with the geometric center of the levitation structure 200, avoiding swaying or vibration caused by eccentric magnetic force generated by the magnet.

[0054] The cross-sectional shape of the rod-shaped suspension structure 200 can be circular, square, or other polygonal, and the specific design is determined according to the size of the magnet and the shape of the suspension space. A circular rod-shaped structure is beneficial for achieving uniform force distribution and simplifying the machining process, while a square or polygonal cross-section can facilitate the matching and positioning with the base assembly 100.

[0055] By setting the suspension structure 200 and the first magnet 310 coaxially, the symmetrical distribution of magnetic field lines in the magnetic levitation device can be ensured, the influence of radial force and torsional force can be reduced, the dynamic stability and response speed of the suspension structure can be improved, and the requirements of the magnetic levitation system in terms of precise positioning and high dynamic performance can be met.

[0056] In one embodiment, the levitation structure 200 is a levitation pen, specifically including a pen cap 210 and a pen barrel 220. The pen barrel 220 serves as the main structure of the levitation pen, supporting the second magnet 320 and the third magnet 330, both of which are mounted on the pen barrel 220 to achieve magnetic levitation support and positioning of the levitation pen. The pen cap 210 is detachably connected to the pen barrel 220, allowing users to easily attach and detach the cap as needed, meeting the requirements of different usage scenarios. For example, the cap 210 can be attached when in use and removed when storing or not in use, thereby reducing the overall size or making it easier to carry.

[0057] The pen barrel 220 is suspended within the suspension groove 111 of the base assembly 100, and the pen barrel 220 and the suspension groove 111 are coaxially arranged. This coaxial design ensures that the axis of the pen barrel 220 is aligned with the axis of the suspension groove 111, guaranteeing the symmetry of the magnetic field distribution and reducing the eccentric force and torque caused by uneven magnetic force. This improves the stability and balance of the suspended pen, facilitating the static suspension and precise control of the pen barrel 220. The size and shape of the suspension groove 111 should match the outer diameter of the pen barrel 220, ensuring that the pen barrel 220 can suspend smoothly and move flexibly, while avoiding wobbling or instability of the pen barrel 220 due to excessive gaps.

[0058] The cap 210 of the hovering pen is preferably positioned upwards, that is, the cap 210 is located at the upper end of the pen barrel 220. This design can avoid the cap 210 from adversely affecting the center of gravity and hovering state of the hovering pen, and helps to maintain the overall balance of the hovering pen. In addition, the upward-facing structure of the cap 210 makes it easier for users to pick up and put away the hovering pen, improving ease of use.

[0059] The pen barrel 220 contains a refill, which can be a traditional ink pen refill, a ballpoint pen refill, or other writing media, ensuring the basic writing function of the hover pen. The installation position and structure of the refill should match the internal space of the pen barrel 220 to ensure smooth writing and easy replacement of the refill.

[0060] Specifically, the pen cap 210 includes a cap body 211 and an iron ring 212. The cap body 211 serves as the main structure of the pen cap, and its shape and size are adapted to the end structure of the pen barrel 220, facilitating a stable and convenient connection. The iron ring 212 is disposed on the cap body 211 and is usually fixed to the inside or bottom of the cap body 211 by means of embedding, bonding, or mechanical snap-fit. The iron ring 212 is made of a soft magnetic material with good magnetic permeability, such as silicon steel sheet, soft iron, or nickel-iron alloy, to ensure that it can generate an effective magnetic attraction force with the magnetic attractor 225.

[0061] The pen barrel 220 includes a barrel body 221 and a magnetic chuck 225. The barrel body 221 serves as the main frame of the levitating pen, supporting the internal magnets and the pen tip. Its shape and size are designed to meet the stability requirements of the levitating structure and the writing function. The magnetic chuck 225 is disposed on the barrel body 221, preferably at or near the end of the barrel body 221. The magnetic chuck 225 can be a ring magnet, square magnet, or other shaped magnet made of permanent magnet material. Its material can be high-performance permanent magnet materials such as neodymium iron boron to ensure the stability and reliability of the magnetic connection.

[0062] The iron ring 212 and the magnetic component 225 are magnetically attracted to each other to connect the pen cap 210 and the pen barrel 220. This magnetic connection method has the advantage of convenient assembly and disassembly. Specifically, the magnetic component 225 and the iron ring 212 form a magnetic force, which can achieve a stable connection without the need for mechanical fasteners. The user only needs to bring the pen cap 210 close to the end of the pen barrel 220, and the magnetic force will automatically attract and fix it. Disassembly can be done by simply pulling it apart gently, without the need for additional tools, thus improving the convenience of use and user experience.

[0063] Furthermore, the structure of the magnetic component 225 and the iron ring 212 can be designed as surface contact or surrounding contact to ensure contact area and uniform adsorption, which is beneficial to improving the stability of the connection and reducing the risk of loosening caused by vibration or external force. The iron ring 212 can be designed as an open ring, a closed ring, or a multi-segmented ring, which can be flexibly selected according to the structural layout and manufacturing process of the cap body 211 to adapt to different assembly requirements.

[0064] In addition to magnetic attraction, the detachable connection between the cap 211 and the barrel 221 can also incorporate auxiliary structures such as snap-fits, threads, or pins to enhance connection reliability and prevent the cap 210 from accidentally detaching under significant impact or vibration. For example, an inner and outer snap-fit ​​structure can be provided between the cap 211 and the barrel 221. This snap-fit ​​structure can be positioned on the inner wall of the cap 211 and the outer wall of the barrel 221, providing a mechanical locking function. A threaded connection structure achieves fastening through rotation, suitable for applications requiring high connection strength. These auxiliary structures compensate for the limitations of magnetic attraction, ensuring that the connection performance between the cap 210 and the barrel 220 meets the requirements of various usage environments.

[0065] In one embodiment, the magnetic suction component 225 includes two parts: an adsorption magnet 2251 and a mounting base 2252. The mounting base 2252 is coaxially arranged with the rod body 221. The adsorption magnet 2251 is disposed in the mounting base 2252 and is used to achieve magnetic adsorption connection with the iron ring 212.

[0066] The adsorption magnet 2251, as the core magnetic component of the magnetic attractor 225, can take various shapes, such as a ring magnet, a square magnet, or a cylindrical magnet. The specific shape and size can be designed according to the structural dimensions of the pen barrel 220 and the required magnetic attraction force. The material of the adsorption magnet 2251 can be high-performance permanent magnet materials such as neodymium iron boron or aluminum nickel cobalt to ensure the stability of the magnetic connection and the strength of the magnetic force.

[0067] The mounting base 2252, serving as a support and positioning structure for the adsorption magnet 2251, is typically made of plastic, metal, or composite materials. The mounting base 2252 is coaxially aligned with the rod body 221, which helps ensure that the magnetic axis of the adsorption magnet 2251 coincides with the axis of the pen barrel 220, ensuring symmetrical magnetic field distribution, reducing eccentric torque, and contributing to the overall stability of the levitating pen structure. The size and shape of the mounting base 2252 should be adapted to the size of the adsorption magnet 2251 to achieve accurate positioning and fixation of the adsorption magnet 2251, preventing displacement or loosening of the adsorption magnet 2251 during use.

[0068] The mounting base 2252 can be in the form of an annular groove, a cylindrical cavity, or a nested base, etc. The specific structural design should ensure that the adsorption magnet 2251 can be firmly embedded or fixed within the mounting base 2252, while also facilitating assembly and maintenance. The connection between the mounting base 2252 and the rod body 221 can be achieved through various methods such as interference fit, bonding, threaded connection, or mechanical snap-fit. The specific choice depends on the structural strength requirements and manufacturing process. Interference fit offers the advantages of simple structure and reliable fixation, bonding facilitates sealing and dust prevention, while threaded connections and snap-fit ​​structures facilitate disassembly and replacement.

[0069] By positioning and fixing the magnetic magnet 2251 with the mounting base 2252, the magnetic field axis of the magnetic component 225 can be kept aligned with the axis of the pen barrel 220, avoiding uneven magnetic force and unstable connection of the pen cap 210 caused by magnet misalignment, thereby improving the stability and reliability of the levitation pen during use. At the same time, the presence of the mounting base 2252 simplifies the assembly process of the magnetic component 225, improves production efficiency, and reduces assembly errors.
