[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] There may be uneven materials or manufacturing defects in the manufacturing process of the magnetic wheel, resulting in uneven distribution of the magnetic field. The design of the magnetic wheel leads to uneven distribution of magnetic poles, resulting in divergence of magnetic flux lines.

[0034] To address these issues, see Figures 1 to 3 The utility model proposes a magnetic wheel 100, comprising a magnetic core 1, at least one magnet 2 and at least one magnetic conductive magnetic wheel 3: the magnetic core 1 is a weak magnetic core 1 or an absolute magnetic core 1, and the at least one magnet 2 is installed on the peripheral side surface of the magnetic core 1; the at least one magnetic conductive magnetic wheel 3 is installed on the peripheral side surface of the magnetic core 1 and is adjacent to the at least one magnet 2.

[0035] The technical solution of the utility model adopts a weak magnetic core 1 or an absolute magnetic core 1 to prevent or inhibit part of the magnetic flux lines from returning to the magnetic pole through the middle, thereby reducing or losing the density of the magnetic flux lines passing through the adsorbed body. The magnetic flux lines are concentrated by the magnetic conductive wheel 3, the magnetic flux lines density of the adsorbed body is increased, and the adsorption force of the magnetic wheel 100 is improved.

[0036] In one embodiment, two magnetic conductive wheels 3 are provided, and the two magnetic conductive wheels 3 are respectively installed at two ends of the magnetic core 1 , and the at least one magnet 2 is sandwiched between the two magnetic conductive wheels 3 .

[0037] It is understandable that the magnetic wheels 3 at both ends are conducive to concentrating the magnetic lines of force, thereby improving the magnetic effect of the magnet 2. At the same time, the magnet 2 is clamped between the two magnetic wheels 3 to reduce vibration and displacement, thereby ensuring the stable position of the magnet 2.

[0038] In one embodiment, a plurality of magnets 2 are provided, and the plurality of magnets 2 form a magnet 2 array, and the magnet 2 array is adjacent to the at least one magnetic conductive wheel 3 .

[0039] It is understandable that the array of magnets 2 can be designed into different shapes and sizes according to the required magnetic core 1 and actual needs. By adjusting the number and arrangement of the magnets 2, precise control of the strength and distribution of the magnetic flux lines can be achieved, thereby enhancing the applicability and flexibility of the magnetic wheel 100.

[0040] In one embodiment, each of the magnets has an N pole and an S pole that are arranged opposite to each other, and in the magnet array, the N poles and S poles of adjacent magnets are arranged alternately.

[0041] It can be understood that by alternately arranging the N poles 21 and the S poles 22, adjacent magnets 2 are closely fitted, which effectively reduces magnetic field leakage, makes the magnetic flux lines more concentrated in the working area of ​​the magnetic wheel 100, and forms a closed magnetic flux path, thereby enhancing the magnetic flux and ensuring that the distribution of the magnetic flux lines around the magnetic wheel 100 is more concentrated, which is beneficial to improving the adsorption force of the magnetic wheel 100.

[0042] In one embodiment, the number of magnets 2 in the magnet 2 array is an even number.

[0043] It is understandable that an even number of magnets 2 can ensure that the polarities of both ends of the magnet 2 array match each other, thereby forming a closed magnetic field loop that helps reduce magnetic field leakage and makes the magnetic flux lines more concentrated in the working area of ​​the magnetic wheel 100.

[0044] In one implementation, the weak magnetic core 1 includes a copper core 1 , an aluminum alloy core 1 , or a stainless steel core 1 .

[0045] It can be understood that the copper core 1 can conduct away the heat generated by the magnetic wheel 100 during operation due to its excellent thermal conductivity; the aluminum alloy has a lower density, which can reduce the weight of the aluminum alloy core 1; the stainless steel core 1 provides better corrosion resistance and mechanical strength, is suitable for harsh environments, and extends the service life of the magnetic wheel 100.

[0046] In one embodiment, the magnetic conductive magnetic wheel includes a pure iron magnetic wheel, a carbon steel magnetic wheel, an iron silicon magnetic wheel, an iron aluminum magnetic wheel, a nickel iron magnetic wheel or an iron cobalt magnetic wheel.

[0047] Understandably, pure ferromagnetic wheels have high permeability and saturation flux density and are suitable for applications requiring high permeability;

[0048] The carbon steel magnetic wheel has a high magnetic permeability and can effectively conduct and concentrate magnetic flux lines. In addition, carbon steel has good mechanical strength and can withstand certain mechanical loads and vibrations, ensuring the stability and durability of the magnetic wheel 100. At the same time, compared with other magnetic conductive materials, the cost of carbon steel is relatively low, which makes the carbon steel magnetic wheel an economical and practical choice;

[0049] The iron silicon magnetic wheel has high magnetic permeability and low hysteresis loss to reduce eddy current loss and improve efficiency;

[0050] The iron-aluminum magnetic wheel has high magnetic permeability and good magnetic saturation characteristics, as well as good corrosion resistance and mechanical properties;

[0051] Nickel-iron magnetic wheels have very high magnetic permeability and low coercivity, and are suitable for use in situations requiring high precision and high sensitivity.

[0052] Iron-cobalt magnetic wheels have high magnetic permeability and saturation flux density and are suitable for applications requiring high magnetic performance.

[0053] In one embodiment, both end surfaces of the magnetic core 1 have a first connection portion 11 , and the magnetic conductive wheel 3 has a second connection portion 31 at a location corresponding to the end surface of the magnetic core 1 , and the first connection portion 11 is fixedly connected to the second connection portion 31 .

[0054] It is understandable that, through the fixed connection, the positional relationship between the magnetic core 1 and the magnetic conductive wheel 3 is fixed, reducing the possibility of loosening or falling off during use, and enhancing the stability of the entire magnetic wheel 100 in a high-speed rotation or vibration environment. In addition, the first connecting portion 11 and the second connecting portion 31 can be fixed by welding, bolting, bonding or other mechanical fixing methods, which can be designed according to different needs or specifically set in application scenarios.

[0055] In one embodiment, the magnetic wheel 100 also includes a fixing portion, a first hole is formed inside the first connecting portion 11, a second hole is formed at a position of the second connecting portion 31 corresponding to the first hole, one end of the fixing portion passes through the second hole and extends into the first hole, and is fixedly connected to the first connecting portion 11 and the second connecting portion 31.

[0056] It is understandable that the first hole formed inside the first connecting part 11 and the second hole corresponding to the second connecting part 31 provide space for the installation of the fixing part. One end of the fixing part passes through the second hole and extends into the first hole to achieve a fixed connection with the first connecting part 11 and the second connecting part 31. The magnetic core 1, the magnetic wheel 3 and the magnet 2 array form a more stable overall structure. The stable structure can also reduce the risk of performance degradation or failure caused by loose or deformed components. In addition, through the connection of the fixing part, the fixing part can be easily passed through the second hole and fixed in the first hole, making the assembly process simpler and more efficient. When repair or replacement of parts is required, it can also be easily completed by disassembling the fixing part.

[0057] In one embodiment, the two end surfaces of the magnetic core 1 are also protruded to form positioning portions 12, and the magnetic conductive wheel 3 is also provided with positioning grooves 32 at positions corresponding to the positioning portions 12. The positioning portions 12 are inserted into the positioning grooves 32 to adjust the relative positions of the first hole and the second hole and make them face each other.

[0058] It can be understood that the coordinated use of the positioning portion 12 and the positioning slot 32 can ensure that the first hole and the second hole can be correctly aligned. When assembling the magnetic wheel 100, by inserting the positioning portion 12 into the positioning slot 32, the position of the magnetic core 1 and the magnetic conductive magnetic wheel 3 can be easily adjusted so that the relative positions of the first hole and the second hole are accurately aligned, which provides convenience for the subsequent installation of the fixing portion. In addition, the design of the positioning portion 12 and the positioning slot 32 enhances the connection stability and reliability between the magnetic core 1 and the magnetic conductive magnetic wheel 3. The raised positioning portion 12 and the opened positioning slot 32 enable the two to form a tight fit when connected, reducing the risk of performance degradation or failure due to position deviation or looseness.

[0059] In one embodiment, the magnetic conductive wheel 3 further has bar teeth around its outer circumference.

[0060] It is understandable that the bar teeth can cooperate with gears, chains or other transmission systems, so that the magnetic wheel 100 not only serves as a magnetic field conduction component, but also participates in power transmission or motion control. In addition, the bar teeth can increase the roughness of the contact surface, thereby increasing the friction.

[0061] View Figure 4 and Figure 5 In another embodiment, the magnetic wheel 3 is provided with one, the magnet 2 is provided with multiple magnets and forms two magnet 2 arrays, the magnetic wheel 3 is arranged in the middle of the magnetic core 1, and the two magnet 2 arrays are respectively located on both sides of the magnetic wheel 3, wherein the magnets 1 at both ends of the magnetic wheel 3 are both N poles or both S poles.

[0062] In this way, a symmetrical magnetic field can be formed on both sides of the magnetic wheel 3, and the magnetic flux lines are concentrated through the magnetic wheel 3, thereby increasing the magnetic flux line density of the adsorbed object and improving the adsorption force. In this way, the magnetic wheel 100 is applied to the guide wheel, which can reduce the friction force on the magnetic wheel 100 during the steering process and improve the steering flexibility.

[0063] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
