[0026] In order to clearly illustrate the technical solutions of the present application, the terms "front", "back", "left", "right", "up", and "down" are defined as shown in Figure 1

[0027] As shown in Figure 1 The present application provides a laboratory magnetic levitation device 100, which includes a moving track 11, a stator 12, a winding 13, a carrier platform 14, and a mover 15. The stator 12 is connected to the moving track 11, the winding 13 is wound around the stator 12, the winding 13 is connected to a power source to enable the winding 13 to generate an induced magnetic field, the mover 15 is connected to the carrier platform 14 and has magnetic properties, and the stator 12 is located within the induced magnetic field. In the case of three-phase alternating current through the winding 13, the stator 12 can attract the mover 15 to make the carrier platform 14 levitate, and the mover 15 can drive the carrier platform 14 to move along the extension direction of the moving track 11, thereby enabling the carrier platform 14 to transport goods.

[0028] In some embodiments, the moving track 11 can be a straight guide rail or a curved guide rail or a combination of the two, as long as it meets the transportation requirements, and the present application does not limit this.

[0029] ​In some embodiments, the winding 13 is a distributed winding 13, and the magnetic motive force waveform of the induced magnetic field of the distributed winding 13 is close to a sine wave, so that the waveform of the air gap magnetic field in the laboratory magnetic levitation object carrying device 100 can also be closer to a sine wave, which is beneficial to reduce the harmonic content of the induced magnetic field, thereby reducing the loss generated by the harmonics, improving the strength of the induced magnetic field, and then improving the force of the induced magnetic field on the object carrying platform 14, which is beneficial to the object carrying platform 14 to carry heavier objects.

[0030] It should be noted that the winding 13 can also be a concentrated winding 13, which is not limited by the present application.

[0031] Specifically, the stator 12 and the winding 13 are each provided with two groups, the two groups of stators 12 are arranged along the left-right direction and connected to the moving track 11, and the two groups of stators 12 are at least partially located below the moving track 11, and each group of windings 13 is wound around a group of stators 12. In this way, the two groups of stators 12 and the two groups of windings 13 improve the strength of the induced magnetic field, thereby improving the driving force for moving the object carrying platform 14, to improve the carrying and transportation capacity of the laboratory magnetic levitation object carrying device 100. Secondly, the two groups of stators 12 arranged along the left-right direction can provide an induced magnetic field on both sides, which is beneficial to the object carrying platform 14 to maintain balance in the induced magnetic field, thereby improving the moving stability of the object carrying platform 14, and further improving the transportation stability of the laboratory magnetic levitation object carrying device 100.

[0032] In some embodiments, the stator 12 is fixedly connected to the moving track 11 by a screw. The moving track 11 is provided with a mounting hole (not shown in the figure), and the bolt passes through the mounting hole and is fixedly connected to the stator 12. The upper surface of the moving track 11 and the lower surface of the stator 12 are each provided with a counterbore 111, and the two counterbores 111 communicate with the mounting hole. When the screw is connected to the stator 12, the nut and the screw cap of the bolt can be respectively built into the two counterbores 111. In this way, the nut and the screw cap can be prevented from protruding from the moving track 11 to interfere with the movement of the object carrying platform 14.

[0033] In some embodiments, the stator 12 can also be fixed to the moving track 11 by glue.

[0034] In some embodiments, the stator 12 can be fixed to the moving track 11 by glue and a screw, thereby improving the connection stability of the stator 12 and the moving track 11, and improving the transportation stability of the laboratory magnetic levitation object carrying device 100. Meanwhile, the glue fixing can also have the effect of pre-connection, so that the screw can more smoothly fix the stator 12 and the moving track 11.

[0035] In the embodiment, the object carrying platform 14 comprises an object carrying part 141, a moving part 142 and a connecting part 143. The object carrying part 141 is above the moving track 11 and is used to carry objects. The moving part 142 is provided with two moving parts and is below the moving track 11. The connecting part 143 is provided with two connecting parts and is partially connected to the moving track 11 along the left and right directions. The connecting part 143 is used to connect the moving part 142 and the object carrying part 141, so that the moving part 142 can drive the object carrying part 141 to move under the action of the magnetic force.

[0036] Specifically, each moving part 142 is connected with one connecting part 143, and each moving part 142 is below one stator 12. The mover 15 is provided with two groups, and each group of mover 15 is connected to one moving part 142 and at least partially above the corresponding moving part 142. In this way, the mover 15 can be located in the induced magnetic field generated by the stator 12, so that the mover 15 can be driven to move the object carrying platform 14 along the extension direction of the moving track 11 under the action of the magnetic force.

[0037] More specifically, each group of mover 15 is also below one group of stator 12 and has a gap with the corresponding group of stator 12. Through the magnetic force between the mover 15 and the stator 12, the stator 12 can be suspended, so that the object carrying platform 14 connected with the stator 12 can be suspended on the moving track 11, thereby realizing magnetic levitation transportation.

[0038] In some embodiments, each group of mover 15 comprises a first mover 151 and a second mover 152 distributed along the extension direction of the moving track 11. The magnetism of the first mover 151 and the second mover 152 is opposite, so that the induced magnetic field generated by the winding 13 can attract the first mover 151 and repel the second mover 152, or repel the first mover 151 and attract the second mover 152, so that the magnetic force of the induced magnetic field can push the mover 15 and drive the object carrying platform 14 to move through the mover 15. Moreover, the length of each group of mover 15 along the extension direction of the moving track 11 is less than the length of each group of stator 12 along the extension direction of the moving track 11, so that the mover 15 can be moved along the extension direction of the moving track 11 under the action of the induced magnetic field, thereby realizing the object carrying transportation of the laboratory magnetic levitation object carrying device 100.

[0039] It should be noted that along the up-down direction of the laboratory magnetic levitation object carrying device 100, the overlapping area of the stator 12 and the mover 15 is greater than 80% of the upper surface area of the mover 15. In this way, the mover 15 and the stator 12 have enough attractive force to make the mover 15 suspended, and the mover 15 can also have enough area in the induced magnetic field generated by the winding 13, so that the mover 15 can be moved under the action of the magnetic force.

[0040] As an implementation manner, the mover 15 is detachably connected with the moving part 142. In this way, the mover 15 can be conveniently detached and replaced.

[0041] In some embodiments, the mover 15 can be an electromagnet or a permanent magnet, which is not limited in the present application.

[0042] As shown in Figure 1 and Figure 2 In order to avoid the relative deviation of the object platform 14 from the moving track 11 during the movement, the laboratory magnetic levitation object device 100 further comprises a first guide 16 and a second guide 17, which are used to limit the relative position between the object platform 14 and the moving track 11, thereby improving the movement stability of the object platform 14.

[0043] Specifically, the first guide 16 is arranged through one connecting part 143 and abuts against one side of the moving track 11 or has a gap less than 10 mm, and the second guide 17 is arranged through another connecting part 143 and abuts against the other side of the moving track 11 or has a gap less than 10 mm. Wherein, along the left-right direction of the laboratory magnetic levitation object device 100, the first guide 16 and the second guide 17 are distributed on the left and right sides of the moving track 11. In this way, the relative position between the object platform 14 and the moving track 11 can be limited by the first guide 16 and the second guide 17, so as to avoid the deviation of the object platform 14 during the movement, and the overlapping area of the stator 12 and the mover 15 can be kept in the range of more than 80% of the area of the upper surface of the mover 15, so as to improve the levitation stability and the movement stability of the object platform 14, thereby improving the transportation stability of the laboratory magnetic levitation object device 100. In addition, it can also avoid the collision and damage between the object platform 14 and the moving track 11 caused by the deviation of the object platform 14, thereby improving the service life of the laboratory magnetic levitation object device 100 and reducing the use cost.

[0044] In some embodiments, the first guide 16 and the second guide 17 can be provided in plurality, and the plurality of first guides 16 are arranged along the extension direction of the moving track 11, and the plurality of second guides 17 are arranged along the extension direction of the moving track 11. The plurality of first guides 16 and the plurality of second guides 17 can further limit the relative position between the object platform 14 and the moving track 11, thereby further improving the levitation stability and the movement stability of the object platform 14, and further improving the transportation stability of the laboratory magnetic levitation object device 100.

[0045] As an implementation form, the first guide 16 and the second guide 17 each include a guide structure 161 and a shaft structure 162 connected with the guide structure 161, the shaft structure 162 is connected with the connecting part 143 and abuts against one side of the moving track 11 or has a gap less than 10 mm through the guide structure 161. Wherein, the guide structure 161 can move relative to the moving track 11, thereby facilitating the movement of the object platform 14 relative to the moving track 11.

[0046] Specifically, the guide structure 161 is a spherical structure. In this way, the spherical structure moves more smoothly relative to the moving track 11, thereby further facilitating the movement of the object platform 14 relative to the moving track 11.

[0047] As another implementation form, the guide structure 161 is a universal wheel. The universal wheel has a rotational degree of freedom, thereby facilitating the movement of the guide structure 161 relative to the moving track 11.

[0048] In some embodiments, the shaft structure 162 is provided with an external thread, both the connecting parts 143 are provided with a threaded hole extending in the left-right direction, and the shaft structure 162 is threadedly connected with the connecting parts 143. In this way, the relative position of the shaft structure 162 and the connecting part 143 can be adjusted by rotating the shaft structure 162, thereby adjusting the relative position of the guide structure 161 and the moving track 11, so that the guide structure 161 abuts against one side of the moving track 11 or has a gap less than 10 mm, thereby limiting the relative position of the object platform 14 and the moving track 11, to improve the transportation stability of the laboratory magnetic levitation object device 100. Moreover, the first guide 16 and the second guide 17 with adjustable positions can adapt to the different distance requirements between the moving track 11 and the connecting part 143 due to the different sizes of the laboratory magnetic levitation object device 100, thereby improving the versatility of the first guide 16 and the second guide 17.

[0049] For example, rotating the shaft structure 162 in a first direction can make the guide structure 161 close to the moving track 11, and rotating the shaft structure 162 in a second direction can make the guide structure 161 away from the moving track 11, wherein the first direction and the second direction are opposite. In this way, the relative position of the guide structure 161 and the moving track 11 can be adjusted to meet the different distance requirements of the laboratory magnetic levitation object device 100.

[0050] As Figure 2As shown, in one embodiment, the laboratory magnetic levitation transport device 100 also includes a plurality of third guide members 18, the structure of which is the same as that of the first guide member 16. Specifically, the third guide member 18 passes through the transport section 141 and abuts against the upper surface of the moving track 11 or has a gap of less than 5 mm. With this arrangement, in the vertical direction of the laboratory magnetic levitation transport device 100, the third guide member 18 can limit the distance between the transport section 141 and the moving track 11, thereby limiting the relative position of the transport platform 14 and the moving track 11 in the vertical direction. If the transport platform 14 fails to levitate and falls, the third guide member 18 can support the transport platform 14 to prevent the transport platform 14 from colliding with the moving track 11 and causing damage to the transport platform 14 and the moving track 11, further improving the service life of the laboratory magnetic levitation transport device 100 and reducing the cost of use.

[0051] In one embodiment, the moving track 11 extends at least partially downward to form a support structure 112, which is at least partially located between the two stators 12 and at least partially located between the two movers 15.

[0052] In some embodiments, the laboratory magnetic levitation carrier 100 further includes a base 19, which is located below and connected to the support structure 112, so that the moving track 11, the support structure 112, and the base 19 can form an "I"-shaped structure. This arrangement results in higher stability of the "I"-shaped structure, thereby improving the structural stability of the moving track 11.

[0053] In this embodiment, the laboratory magnetic levitation carrier device 100 further includes a three-phase conductor structure 21, which is electrically connected to two sets of windings 13 to provide three-phase alternating current to the windings 13. Specifically, the three-phase conductor structure 21 is mounted on a support structure 112. This arrangement allows the support structure 112 to provide an installation position for the three-phase conductor structure 21, and the support structure 112 can extend along the extension direction of the moving track 11, enabling the three-phase conductor structure 21 to be laid out along the extension direction of the moving track 11. This facilitates the three-phase conductor structure 21 supplying power to the windings 13 laid out along the extension direction of the moving track 11, and avoids messy wiring and tangling of the three-phase conductor structure 21 due to lack of installation position, thereby improving the neatness of the wiring of the three-phase conductor structure 21.

[0054] like Figure 2 and Figure 3 As shown, in one embodiment, when the mover 15 is an electromagnet, the laboratory magnetic levitation carrier device 100 includes two sets of conductive bars 22 connected to an external power source, which are used to provide power to the mover 15.

[0055] Specifically, the two groups of conductive strips 22 are respectively installed on the two sides of the support structure 112 along the left-right direction. In addition, the conductive strips 22 can be arranged along the extension direction of the moving track 11, so that the mover 15 can keep contact with the conductive strips 22 during movement, so that the mover 15 can always keep magnetic, further improving the transportation stability of the laboratory magnetic levitation object device 100. And, the arrangement direction of the conductive strips 22 can be consistent with the moving direction of the mover 15, which can avoid the cross winding of the conductive strips 22, and is beneficial to improve the arrangement neatness and use safety of the conductive strips 22. In some embodiments, the support structure 112 is provided with a clip, and the conductive strips 22 are connected with the support structure 112 through the clip. In some embodiments, the conductive strips 22 can also be fixed with the support structure 112 through insulating glue, and connected with the support structure 112 through the clip, so as to improve the installation stability of the conductive strips 22.

[0056] More specifically, when the mover 15 is an electromagnet, each group of movers 15 includes a magnet body 153 and a magnet conductive part 154 connected with the magnet body 153, and the magnet conductive part 154 of each group of movers 15 is in contact with a group of conductive strips 22. By such arrangement, the current in the conductive strips 22 can flow to the magnet body 153 through the magnet conductive part 154, so that the magnet body 153 generates a magnetic field, so that the mover 15 and the stator 12 can be attracted to each other, and then the object platform 14 can be suspended and pushed by the induced magnetic field generated by the winding 13. Secondly, the electromagnet can control the magnetic field strength by controlling the current size, so in this embodiment, the current size flowing in the magnet body 153 is controlled by controlling the current size in the conductive strips 22, so as to control the magnetic field strength generated by the magnet body 153, and then the suspension height of the object platform 14 and the transportation speed of the object platform 14 can be controlled, which is beneficial to meet different transportation needs.

[0057] More specifically, referring to Figure 4 , the length of the magnet conductive part 154 is greater than the maximum distance between the conductive part and the magnet body 153, so that when the magnet conductive part 154 is in contact with the conductive part, the magnet conductive part 154 has a redundant segment 1541, which enables the magnet conductive part 154 to always be in contact with the conductive part. By such arrangement, the connection stability of the magnet conductive part 154 and the conductive part can be improved during the movement of the mover 15, so as to avoid the magnet conductive part 154 and the conductive part from being separated, so that the magnet body 153 no longer generates a magnetic field, so as to avoid the mover 15 from being unable to interact with the stator 12, so that the object platform 14 cannot be suspended, and the mover 15 cannot be pushed by the induced magnetic field generated by the winding 13, which can further improve the transportation stability of the laboratory magnetic levitation object device 100.

[0058] In some embodiments, the magnet body 153 is made of soft iron, and the magnet conducting part 154 includes a wire and a brush, wherein two ends of the wire are connected with the magnet body 153 and the brush respectively, and the brush is in contact with the conducting part to electrify the magnet body 153 and the conducting part. The wire is elastic, and after the brush is in contact with the conducting part, the wire can be deformed, and the deformed wire can generate a force to make the brush always in contact with the conducting part, thereby improving the connection stability of the magnet conducting part 154 and the conducting part.

[0059] As an implementation, when the mover 15 is an electromagnet, the mover 15 adopts an electromagnet with a pole shoe structure 155. Specifically, the pole shoe structure 155 is arranged on the side of the mover 15 close to the stator 12. In this way, the pole shoe structure 155 can improve the uniformity of the magnetic field generated by the electromagnet, thereby facilitating the improvement of the magnetic field strength of the mover 15, and further improving the attraction force between the mover 15 and the stator 12, so as to improve the suspension stability of the mover 15 and the object carrying platform 14, and also improve the thrust of the induced magnetic field generated by the winding 13 on the mover 15, which is conducive to improving the moving speed of the mover 15 and the object carrying platform 14, thereby improving the transportation efficiency of the laboratory magnetic levitation object device 100.

[0060] As another implementation, when the mover 15 is a permanent magnet, the laboratory magnetic levitation object device 100 does not need to use the conducting strip 22 to provide power for the mover 15, so as to make the mover 15 and the stator 12 attract each other, and make the mover 15 be pushed by the induced magnetic field generated by the coil, so as to make the object carrying platform 14 move, thereby realizing the object transportation of the laboratory magnetic levitation object device 100, and facilitating the simplification of the structure of the laboratory magnetic levitation object device 100.

[0061] As shown in Figure 5 As an implementation, the three-phase wire structure 21 includes a first three-phase wire 211 and a second three-phase wire 212. Specifically, the first three-phase wire 211 is provided with two groups, and the two groups of first three-phase wires 211 are respectively installed on the left and right sides of the support structure 112 along the left-right direction, and the second three-phase wire 212 is installed on one side of the support structure 112 along the front-rear direction. Among them, the two groups of first three-phase wires 211 are respectively electrically connected with the two groups of windings 13. In this way, the two groups of first three-phase wires 211 and the second three-phase wire 212 can respectively use the installation positions of the support structure 112 along the left-right direction and the front-rear direction, thereby avoiding the overlapping winding of the first three-phase wire 211 and the second three-phase wire 212, and facilitating the improvement of the wiring neatness of the three-phase wire structure 21.

[0062] In some embodiments, the first three-phase wire 211 and the second three-phase wire 212 are connected to the support structure 112 by buckling and fixed glue, so as to improve the connection stability of the first three-phase wire 211 and the second three-phase wire 212 on the support structure 112.

[0063] In the present embodiment, the second three-phase wire 212 is connected to an external power supply, and the two groups of first three-phase wires 211 are detachably connected to the second three-phase wire 212 through the wire 214, so that the second three-phase wire 212 supplies power to the two groups of first three-phase wires 211, and the second three-phase wire 212 supplies power to the winding 13, so that the winding 13 generates an induced magnetic field.

[0064] In some embodiments, the first three-phase wire 211 and the second three-phase wire 212 each include an A-phase, a B-phase, and a C-phase. The A-phase, the B-phase, and the C-phase of the two groups of first three-phase wires 211 each correspond to the A-phase, the B-phase, and the C-phase of the second three-phase wire 212 and are detachably connected through the wire 214. In this way, when it is necessary to perform a phase loss experiment on the laboratory magnetic levitation load device 100, the connection wire 214 of the corresponding phase of the two groups of first three-phase wires 211 and the second three-phase wire 212 is disconnected, and the influence of the phase loss on the performance of the laboratory magnetic levitation load device 100 can be tested, so as to simplify the experimental operation steps and improve the convenience of use and implementation of the laboratory magnetic levitation load device 100.

[0065] For example, when it is necessary to perform a performance influence experiment of the laboratory magnetic levitation load device 100 in the case of A-phase loss, the wire 214 between the A-phase of the two groups of first three-phase wires 211 and the second three-phase wire 212 is disconnected, and the performance of the laboratory magnetic levitation load device 100 in the case of A-phase loss and the performance of the laboratory magnetic levitation load device 100 in the case of three-phase connection can be compared.

[0066] In some embodiments, the first three-phase wire 211 and the second three-phase wire 212 each include an A-phase terminal, a B-phase terminal, and a C-phase terminal, and the two ends of the wire 214 are wound and connected to the corresponding terminals of the first three-phase wire 211 and the second three-phase wire 212. When it is necessary to perform a phase loss experiment, the wire connecting the corresponding phase of the first three-phase wire 211 and the second three-phase wire 212 is only needed to be disconnected, so as to realize the detachable connection of the first three-phase wire 211 and the second three-phase wire 212 through the wire 214.

[0067] As another implementation, the three-phase wire structure 21 includes two groups of first three-phase wires 211, a second three-phase wire 212 and a standby three-phase wire 213. The two groups of first three-phase wires 211 are respectively electrically connected with the two groups of windings 13. Among them, the two groups of first three-phase wires 211 are installed on the left and right sides of the support structure 112 along the left-right direction, the second three-phase wire 212 is installed on one side of the support structure 112 along the front-back direction, and the standby three-phase wire 213 is installed on one side of the support structure 112 along the front-back direction. The standby three-phase wire 213 is detachably connected with one group of first three-phase wires 211 through the wire 214, and the second three-phase wire 212 is detachably connected with the other group of first three-phase wires 211 through the wire 214. In this way, the second three-phase wire 212 and the standby three-phase wire 213 can provide three-phase alternating current for the two groups of first three-phase wires 211 respectively, so as to avoid the complexity of wiring between the two groups of first three-phase wires 211 and the second three-phase wire 212 caused by supplying power to the two groups of first three-phase wires 211 only through the second three-phase wire 212, so as to avoid the winding of the wires, thereby improving the wiring and use convenience of the three-phase wire structure 21. Moreover, it can also avoid the insufficient wiring space of the second three-phase wire 212 caused by wiring only through the second three-phase wire 212, thereby further improving the wiring convenience of the three-phase wire structure 21.

[0068] In addition, through the above arrangement, the influence of the different phase characteristics of the current input by the two groups of windings 13 on the performance of the laboratory magnetic levitation load device 100 can be measured during the experiment. For example, the A-phase wire between the second three-phase wire 212 and the first three-phase wire 211 can be disconnected, and the B-phase wire between the standby three-phase wire 213 and the other first three-phase wire 211 can be disconnected, so that the current input by the two groups of windings 13 has different phase characteristics, thereby facilitating the performance test of the laboratory magnetic levitation load device 100 and improving the test convenience of the laboratory magnetic levitation load device 100.

[0069] As an implementation, along the front-back direction of the laboratory magnetic levitation load device 100, the second three-phase wire 212 and the standby three-phase wire 213 are located on one side of the support structure 112, and the second three-phase wire 212 and the standby three-phase wire 213 are arranged in overlap. In this way, the compactness of the structure of the second three-phase wire 212 and the standby three-phase wire 213 can be improved, which is conducive to reducing the overall space occupancy of the second three-phase wire 212 and the standby three-phase wire 213, thereby providing more space for the layout of the wire 214, thereby improving the utilization rate of the laboratory magnetic levitation load device 100.

In this way, the mortise and tenon connection does not need to use screws or other fixing parts, so as to simplify the assembly process of the left loading part 1411 and the right loading part 1412. Moreover, the mortise and tenon connection can make the upper surface of the loading part 141 more flat, thereby facilitating the loading and transportation of the loading part 141.

[0071] In the present embodiment, the first mortise and tenon structure 1411a and the second mortise and tenon structure 1412a are coated with lubricating liquid, thereby facilitating the connection of the first mortise and tenon structure 1411a and the second mortise and tenon structure 1412a.

In this way, the connection of the left loading part 1411 and the right loading part 1412 can be realized by installing the third mortise and tenon structure 1413.

[0073] In the present embodiment, the first mortise and tenon structure 1411a, the second mortise and tenon structure 1412a and the third mortise and tenon structure 1413 are coated with lubricating liquid, thereby facilitating the connection of the first mortise and tenon structure 1411a and the third mortise and tenon structure 1413, and facilitating the connection of the second mortise and tenon structure 1412a and the third mortise and tenon structure 1413.
