[0030] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0031] Currently, most existing magnetic conductive devices are made of a single material. However, this method of directly using a single material magnetic core rod may cause a large amount of magnetic field to leak in unexpected directions, resulting in a weakening of the field strength and disorder of the magnetic ring's orientation, which in turn leads to a decrease in magnetic performance, making it impossible to achieve the expected results and difficult to adapt to various scenarios.

[0032] Therefore, in response to the aforementioned problems, this disclosure provides a magnetic guiding device that can clearly divide a magnetic rod into multiple magnetic guiding segments. During magnetization, the synergistic effect of each magnetic guiding segment allows the magnetic field to be more concentrated along a preset main path, effectively reducing the dispersion of the magnetic field in non-main path directions or axial directions. This guides the magnetic ring powder to be uniformly and efficiently magnetized mainly along the main path direction, resulting in improved magnetic properties that meet expectations and are suitable for various scenarios.

[0033] First, this disclosure provides a magnetically conductive device. Please refer to... Figure 1 , Figure 1 This is a structural block diagram of a magnetic conductive device provided in an embodiment of this disclosure. Figure 1 As shown, the device includes:

[0034] The magnetic ring powder cavity 101 is used to contain the magnetic ring powder.

[0035] Magnetizing coil 102 is used to generate a magnetic field during charging;

[0036] The first magnetically conductive section 103 is used to receive the magnetic field, so that the magnetic ring powder is guided by the magnetic field along the main path.

[0037] The second magnetic conductive section 104 is connected to one side of the first magnetic conductive section and is used to suppress the reception of the magnetic field, so that the magnetic ring powder reduces non-main path or axial magnetic conduction.

[0038] The third magnetic conductive section 105 is connected to the other side of the first magnetic conductive section and is used to suppress the reception of the magnetic field, so that the magnetic ring powder reduces non-main path or axial magnetic conduction.

[0039] In this disclosure, the magnetic ring powder cavity 101 can be understood as a structural space or container component for accommodating and positioning magnetic ring powder, and its shape and size can be flexibly adjusted according to actual needs.

[0040] In this disclosure, the magnetizing coil 102 can be understood as an electromagnetic coil assembly used to generate a magnetizing magnetic field. A high-intensity pulsed magnetic field can be generated by passing an instantaneous current through it, providing a magnetic field source for the subsequent magnetization process. In other words, the magnetizing coil is a magnetic field generating component for realizing the directional magnetization of the magnetic ring powder.

[0041] In this disclosure, the magnetically conductive section can be understood as a magnetic circuit component with good magnetic permeability, including at least one such as a magnetically conductive block, magnetically conductive pillar, magnetically conductive plate, or magnetically conductive rod. The first magnetically conductive section 103 can be understood as the main channel section in the magnetically conductive path, and its cross-sectional area is typically matched to the magnetic permeability requirements of the magnetic ring powder, and it is made of a high-permeability material to reduce magnetic resistance. The second magnetically conductive section 104 and the third magnetically conductive section 105 are branches or extensions of the magnetically conductive path, respectively used to divert or guide the magnetic field conducted by the first magnetically conductive section, thereby achieving magnetic field concentration in specific areas of the magnetic field.

[0042] Specifically, in the magnetic conduction process, the magnetic ring powder is first filled into a pre-defined magnetic ring powder cavity, ensuring a tight magnetic circuit connection between the cavity and the first magnetic conduction section. Then, the magnetizing coil is charged, and by controlling the magnitude and duration of the charging current, a magnetic field of a preset intensity is generated. This magnetic field first acts on the first magnetic conduction section. Due to the low magnetic resistance of the first magnetic conduction section, the magnetic field can quickly conduct within it, thereby driving the magnetic ring powder to oriented radially along the first magnetic conduction section, completing the radial magnetic conduction process. Simultaneously, the second and third magnetic conduction sections can suppress leakage magnetic field around the first magnetic conduction section and guide it towards the first magnetic conduction section. This avoids wasting magnetic field energy and further improves the magnetic conduction efficiency and magnetic property uniformity of the magnetic ring powder.

[0043] The first magnetically conductive section in the magnetically conductive device of this disclosure will be described in detail below, including:

[0044] The first magnetic guide section is set along the main road direction, penetrating the central area of ​​the magnetic ring powder cavity.

[0045] In this disclosure, the first magnetically conductive section can be located in the area where the central axis of the magnetic ring powder cavity coincides with the direction of the main magnetic field. Its axial extension path completely covers the core magnetization area of ​​the magnetic ring powder, so that the energy of the main magnetic field can directly act on the area of ​​the material to be magnetized.

[0046] The cross-sectional area of ​​the first magnetic conductive section corresponds to the magnetization region of the magnetic ring powder, and is greater than or equal to the cross-sectional areas of the second and third magnetic conductive sections.

[0047] In this disclosure, the cross-sectional area can be understood as the cross-sectional area of ​​the magnetically conductive segment perpendicular to the direction of magnetic field conduction. In the embodiments of this disclosure, the cross-sectional area of ​​the first magnetically conductive segment matches the projected area of ​​the magnetized region of the magnetic ring powder, thus ensuring that the magnetic field coverage is seamless. Simultaneously, its value is set to be no less than the cross-sectional area of ​​the second and third magnetically conductive segments, forming a "narrow at the front, wide in the middle, and narrow at the back" or "equal width" magnetic circuit structure, avoiding bottleneck effects during magnetic field transmission that could affect magnetic conductivity.

[0048] The first magnetic guide section has a chamfered structure on the side near the magnetic ring powder cavity; the chamfered structure is used to reduce magnetic field scattering.

[0049] In this disclosure, the chamfered structure can be understood as a transition structure with a specific curvature or tilt angle formed at the edge where the first magnetically conductive section contacts the magnetic ring powder cavity through at least one form such as machining. This structure can be used to eliminate magnetic field distortion caused by right-angled edges. In the embodiments of this disclosure, the first magnetically conductive section can be integrally formed from a nanocrystalline alloy material. The chamfered structure on the side near the magnetic ring powder cavity is a rounded transition or an oblique transition. The specific parameters can be determined according to the particle size distribution and magnetization uniformity requirements of the magnetic ring powder.

[0050] The first magnetically conductive section is determined based on the magnetically conductive material; the magnetically conductive material includes at least one of the following: pure iron, silicon steel, and permalloy.

[0051] In this disclosure, the first magnetically conductive section is made of a highly conductive magnetically conductive material. Pure iron has high permeability and saturation magnetic induction, resulting in low magnetic loss in low-frequency magnetic fields, making it suitable as the material for the first magnetically conductive section where high magnetic efficiency is required. Silicon steel, by adding silicon to iron, reduces hysteresis and eddy current losses, making it suitable for magnetic conductivity requirements in medium- and high-frequency magnetic field scenarios. Permalloy material has extremely high permeability, exhibiting excellent magnetic conductivity, especially under weak magnetic field conditions, making it suitable for magnetic conductivity applications requiring high magnetic field sensitivity.

[0052] The surface of the first magnetically conductive section is provided with a magnetically reinforcing coating or magnetically conductive particles; the magnetically reinforcing coating includes at least one of the following: ferrite coating, nanocrystalline coating; the magnetically conductive particles include at least one of the following: neodymium iron boron particles, iron silicon aluminum particles.

[0053] In this disclosure, the magnetically enhanced coating can be understood as a functional thin film layer attached to the surface of the first magnetically conductive segment through at least one process such as spraying, electroplating, or sintering. Ferrite coatings possess high resistivity and good high-frequency magnetic permeability, reducing eddy current losses, while nanocrystalline coatings, with their ultrafine grain structure, exhibit excellent permeability and magnetic stability. Magnetic particles can be understood as micron- or nanometer-sized magnetic particles distributed on the surface of the first magnetically conductive segment through embedding, bonding, or other methods, which can enhance the local magnetic field strength through the magnetic coupling effect between particles. Neodymium iron boron particles have extremely high energy product, significantly improving the local magnetic field strength. Ferrosilicon aluminum particles combine moderate magnetic permeability with low hysteresis loss characteristics, suppressing high-frequency eddy current effects while enhancing the magnetic field. In the embodiments of this disclosure, the surface of the first magnetically conductive segment can flexibly select at least one of a single coating, a composite coating, or a magnetic particle arrangement method, depending on the application scenario.

[0054] The first magnetic guide section is equipped with a magnetic flux guide groove; the magnetic flux guide groove is used to guide the magnetic field to flow along the main path direction.

[0055] In this disclosure, the magnetic flux guiding groove can be understood as a groove structure formed on the surface of the first magnetically conductive section according to a preset path. Its orientation can be consistent with the main magnetic field path direction, and the magnetic field is forced to flow along the groove trajectory by changing the local magnetic reluctance distribution. In the embodiments of this disclosure, the magnetic flux guiding groove can be designed as a strip-shaped groove, evenly distributed along the axial direction of the first magnetically conductive section, which can further reduce the magnetic reluctance in the groove and improve the directional transmission efficiency of the magnetic field under the constraint of the guiding groove.

[0056] The height of the first magnetic conductive section is consistent with the height of the magnetic ring powder cavity; the magnetic ring powder cavity is an unformed cavity.

[0057] In this disclosure, by keeping the height of the first magnetically conductive section consistent with the height of the magnetic ring powder forming cavity, the magnetically conductive structure and the magnetic ring powder can achieve precise spatial matching before forming, effectively reducing the magnetic circuit gap, improving the magnetic energy conduction efficiency, and laying the foundation for the stable performance of magnetic properties during the subsequent magnetic ring forming process, avoiding magnetic interference or energy loss problems caused by the mismatch between the height of the magnetically conductive section and the cavity.

[0058] The connection between the first magnetic section and the second and third magnetic sections includes at least one of the following: threads and keyways.

[0059] In this disclosure, the connection between the magnetically conductive sections is a mechanical connection. Specifically, a threaded connection can be achieved by machining external threads at the end of the first magnetically conductive section and internal threads at the connecting ends of the second and third magnetically conductive sections, thus enabling a detachable connection through thread engagement, facilitating later maintenance and component replacement; a keyway connection can be achieved by machining keyways on the connecting surfaces of the first magnetically conductive section and the second and third magnetically conductive sections, thus achieving circumferential fixation through the embedding of key blocks, ensuring the structural stability and magnetic circuit continuity of the connection. For example, Figure 2 This is a schematic diagram of the structure of a magnetically conductive segment provided in an embodiment of this disclosure. Figure 2 As shown: The first magnetically conductive segment is connected to the upper second or third magnetically conductive segment, and the lower third or second magnetically conductive segment, using either threads or keyways. If a keyway connection is used, circumferential fixation is achieved by the key block at the end of the first magnetically conductive segment engaging with the keyway of the mating magnetically conductive segment. If a threaded connection is used, circumferential fixation is achieved through the tight engagement of the internal and external threads, ensuring structural stability after the magnetically conductive segments are connected and allowing continuous magnetic conduction at the connection points. It is important to note the connection angles and shapes between the first and second / third magnetically conductive segments. Figure 2 This is just a schematic diagram. The design can be flexibly adapted to the magnetization path requirements of the magnetic ring powder, such as using straight-line connection, L-shaped corner connection, or stepped transition connection, as long as the requirements for magnetic field conduction efficiency and structural strength are met.

[0060] When using the first magnetically conductive segment for magnetic conduction, within the first interval, the first magnetically conductive segment conducts magnetic conduction along the main path; within the first interval or the second interval, the second magnetically conductive segment and / or the third magnetically conductive segment blocks the non-main path direction or axial concentration of the magnetic field.

[0061] In this disclosure, the first interval can be understood as a specific time interval from the generation of magnetic field lines after the magnetizing coil is charged to the completion of accumulation within the first magnetically conductive section. The duration of this interval can be adjusted according to at least one of the following: the current intensity of the magnetizing coil, the material properties of the first magnetically conductive section, and the structural dimensions.

[0062] In this disclosure, the second interval can be understood as the time interval during which the magnetic field enters a stable or decaying phase after completing the radial magnetic conduction of the first magnetic conduction segment. During this phase, the magnetic field lines of the second and third magnetic conduction segments are blocked, which can further avoid unnecessary loss of magnetic field energy.

[0063] Specifically, at the beginning of the first interval, a momentary current can be passed through the magnetizing coil to generate a magnetic field. The magnetic field lines converge towards the first magnetically conductive segment with high permeability. As time progresses, the density of magnetic field lines within the first magnetically conductive segment gradually increases until it reaches a saturation state, at which point it enters the radial divergence stage of magnetic field guidance. Simultaneously, during the first interval or the second interval after the first interval ends, magnetoresistive modulation can be applied to the second and / or third magnetically conductive segments to create a blocking effect on the magnetic field in non-main path directions, preventing the magnetic field lines from diffusing into the axial direction or other non-target directions of the magnetic ring powder. In this way, during the critical stage of main path magnetization, it can be ensured that the magnetic field energy is concentrated on the preset magnetization direction of the magnetic ring powder. During the stable or decaying stage of the magnetic field, by continuously blocking the non-main path magnetic field, energy loss is further reduced, ultimately achieving efficient directional magnetization of the magnetic ring powder.

[0064] The second and / or third magnetic conductive sections in the magnetic conductive device of this disclosure will be described in detail below, including:

[0065] The second and / or third magnetic conductive segments are connected to the first magnetic conductive segment at a preset angle.

[0066] In this disclosure, the preset angle can be understood as the angle formed between the second and / or third magnetically conductive segments and the first magnetically conductive segment at the connection point. This angle is determined according to the magnetic circuit turning requirements and the magnetic field uniformity target, and is used to regulate the turning efficiency of the magnetic field at the connection point of the magnetically conductive segments. In the embodiments of this disclosure, the second and / or third magnetically conductive segments can be connected to the first magnetically conductive segment at an angle of 90°-135°. The 90° angle is suitable for compact structures where the magnetic field needs to turn vertically, and the 135° angle is suitable for scenarios requiring a smooth transition of the magnetic field. This can reduce the magnetic field loss at the turning point to within 5%, and can be flexibly adjusted.

[0067] The surface of the second and / or third magnetic conductive sections is provided with magnetic field attenuation grooves; the magnetic field attenuation grooves are used to reflect magnetic fields; the magnetic field attenuation grooves are corrugated.

[0068] In this disclosure, the magnetic field attenuation groove can be understood as a structural groove formed on the surface of the magnetically conductive section for reflecting and absorbing magnetic fields diffused in non-mainstream directions, thereby attenuating stray magnetic fields by changing the magnetic field propagation path. The corrugated shape further increases the complexity of the magnetic field reflection path, enhancing the attenuation effect through the superposition of multiple reflections. Simultaneously, the periodic structure of the corrugations causes the magnetic field energy to form a standing wave effect within the groove, further improving the suppression efficiency of stray magnetic fields. In the embodiments of this disclosure, the magnetically conductive section can have corrugated attenuation grooves continuously arranged on its surface along the length of the section, which attenuates the magnetic field strength in non-mainstream directions.

[0069] The height of the second and / or third magnetic conductive segments is less than or equal to the height of the first magnetic conductive segment.

[0070] In this disclosure, the height of the guiding magnetic segment is specified in the direction perpendicular to its cross-section. This dimensional relationship is designed to accommodate the difference in cross-sectional area to form a gradient magnetic circuit structure. By limiting the height of the second and third guiding magnetic segments, their magnetic permeability can be prevented from exceeding the magnetic flux output range of the first guiding magnetic segment, thus preventing redundant accumulation of the magnetic field in subsequent paths and ensuring the directionality and economy of magnetic energy transfer.

[0071] The second and third magnetic conductive sections are both determined based on non-magnetic materials or shielding layers; non-magnetic materials include at least one of the following: austenitic stainless steel, copper alloy, aluminum alloy, and titanium alloy.

[0072] In this disclosure, the second and third magnetically conductive sections are made of non-magnetic materials or shielding layers. Non-magnetic materials can be understood as materials with permeability close to that of air, making it difficult to conduct magnetic field lines. They can effectively cut off magnetic circuits and prevent magnetic fields from propagating in non-target magnetically conductive sections. These non-magnetic materials include, but are not limited to, at least one of the following: austenitic stainless steel, copper alloys, aluminum alloys, and titanium alloys. Austenitic stainless steel (such as 304, 316, etc.) has extremely low permeability close to that of air, possessing almost no magnetic conductivity. It can block magnetic field conduction while providing stable support and protection for the magnetically conductive structure, making it suitable for magnetically conductive scenarios with high environmental adaptability requirements. Copper alloys (such as brass, bronze, etc.) have good electrical and thermal conductivity, making them suitable for scenarios requiring efficient suppression of magnetic field conduction. Aluminum alloys (such as 6061, 7075, etc.) have a permeability far lower than that of magnetic materials, making them particularly suitable for scenarios with high lightweight requirements (such as miniaturized magnetic ring processing equipment). Titanium alloys (such as the TC4 model) maintain extremely low magnetic permeability, which can block magnetic field conduction while ensuring the structural stability and service life of the magnetically conductive section under complex operating conditions, making them suitable for magnetically conductive systems with high precision and high reliability requirements. The shielding layer can be understood as a functional layered structure that constrains or attenuates the magnetic field through a specific material structure. Its core function is to prevent the magnetic field lines from diffusing to the second and third magnetically conductive sections, ensuring that the magnetic field energy is mainly concentrated in the first magnetically conductive section. Specifically, the shielding layer can be applied to the surface of the second and third magnetically conductive sections, or the main structure of the second and third magnetically conductive sections can be formed directly using non-magnetic materials.

[0073] An arc-shaped transition structure is provided at the end of the second magnetic field section and / or the third magnetic field section; the arc-shaped transition structure is used to disperse the edge magnetic field.

[0074] In this disclosure, the arc-shaped transition structure can be understood as a curved surface structure with continuous curvature formed by machining at the end edges of the second and / or third magnetically conductive sections, used to replace traditional right-angled or acute-angled edges to eliminate magnetic field concentration at the edges. In the embodiments of this disclosure, the specific value of the radius of curvature of the arc-shaped transition structure can be determined according to the end dimensions of the magnetically conductive sections and the magnetic field strength distribution. This determined arc-shaped transition structure can improve the uniformity of the edge magnetic field distribution, effectively avoiding the problem of uneven magnetization of the magnetic ring powder caused by excessively strong local magnetic fields.

[0075] For example, this disclosure also provides a specific process for demonstrating the feasibility of the magnetic permeability method, including:

[0076] Step 1: Use Ohm's law for magnetic circuits to demonstrate the feasibility of the magnetic conduction method.

[0077] In the demonstration process, the magnetic field path can be simplified to a parallel magnetic circuit. The magnetic field lines have two main paths: one is the desired path, which passes through the first magnetically conductive segment and diverges radially (magnetic reluctance R). m The other path is the leakage path, which passes through the second and third magnetic sections (magnetic resistance R1) along the mandrel axis.

[0078] The formula for calculating the magnetic reluctance of a material segment is: R = L / (μ*A), where L is the length, μ is the permeability, and A is the cross-sectional area.

[0079] Therefore, the magnetic reluctance of the first magnetically conductive segment is calculated as: R m ∝1 / (μ r1 *A). The magnetic reluctance for the second and third magnetic segments is calculated as: R1∝1 / (μ r2 *A) Due to μ r1 >>μ r2 Therefore, R1 >> R m Thus, based on the principle that magnetic flux always tends to travel along the path of least magnetic reluctance, the vast majority of the magnetic flux will be confined to the first magnetically conductive section, with only a very small amount leaking through the high-resistance blocking section. This theoretically proves the effectiveness of the design of this invention.

[0080] Step 2: Simulation and comparison using electromagnetic simulation software.

[0081] During the demonstration process, at least one software such as Maxwell Electromagnetic Simulation Software (ANSYS) and Multiphysics Simulation Software (COMSOL) can be used to perform static magnetic field simulation.

[0082] The simulation model parameters can be selected as follows: coil ampere-turns AT = 50; magnetic ring cavity inner diameter 31mm, outer diameter 60mm, height 50mm.

[0083] The simulation result is the average radial magnetic flux density B measured at the mid-plane of the magnetic ring cavity. r It is 2.1T. However, at 10mm from the upper and lower ends of the cavity, B r The voltage drops to 1.3T and 1.2T, with a decay exceeding 40%, and the magnetic field direction tilts. In contrast, the design disclosed here shows that the average B measured at the mid-plane of the magnetic ring cavity... r Increased to 2.5T (an increase of approximately 19%). More importantly, at 10mm from the top and bottom of the cavity, B... r It can still maintain 2.1T and 2.0T, with a decay of less than 20%, and the magnetic field direction maintains good radiality.

[0084] Simulation results: This invention not only significantly improves the field strength in the central region, but also greatly improves the uniformity of the magnetic field distribution along the axis.

[0085] This disclosure also provides a magnetic conduction method, comprising: charging to generate a magnetic field; receiving the magnetic field to cause the magnetic ring powder to undergo main path magnetic conduction; and suppressing the reception of the magnetic field to reduce the non-main path or axial magnetic conduction of the magnetic ring powder.

Figure 4 As shown, a computer-readable storage medium 400 according to an embodiment of the present disclosure stores computer-readable instructions 401 thereon. When the computer-readable instructions 401 are executed by a processor, the magnetic conduction method described with reference to the above figures according to any embodiment of the present disclosure is performed. The computer-readable storage medium includes, but is not limited to, volatile memory and / or non-volatile memory. Volatile memory may include, for example, random access memory (RAM) and / or cache memory. Non-volatile memory may include, for example, read-only memory (ROM), hard disk, flash memory, optical disk, magnetic disk, etc.

[0089] This disclosure further provides a computer program product, including a computer program that, when executed by a processor, implements the magnetic conduction method described in any of the preceding embodiments of this disclosure.

[0090] In summary, this disclosure provides a magnetic guiding device, method, electronic device, storage medium, and program product. This disclosure utilizes a magnetic ring powder cavity to accommodate the magnetic ring powder; a magnetizing coil to generate a magnetic field during charging; a first magnetic guiding segment to receive the magnetic field, causing the magnetic ring powder to be magnetized along its main path; a second magnetic guiding segment connected to one side of the first magnetic guiding segment to suppress the received magnetic field, reducing the magnetic ring powder's magnetization in non-main path or axial directions; and a third magnetic guiding segment connected to the other side of the first magnetic guiding segment to suppress the received magnetic field, further reducing the magnetic ring powder's magnetization in non-main path or axial directions. In summary, the technical solution provided by this disclosure can clearly segment the magnetic guiding device into multiple magnetic guiding segments. During magnetization, the synergistic effect of each magnetic guiding segment allows the magnetic field to be more concentrated along a preset main path, effectively reducing the dispersion of the magnetic field in non-main path or axial directions. This guides the magnetic ring powder to be uniformly and efficiently magnetized mainly along the main path direction, resulting in improved magnetic performance that meets expectations and is adaptable to various scenarios.
