Description

Technical Field

[0001] The invention relates to the technical field of magnetic suspension, in particular to a magnetic repulsion type magnetic suspension device. Background Art

[0002] Magnetic levitation technology refers to a technology that uses magnetic force to overcome gravity to suspend an object. According to the different directions of the magnetic force, magnetic levitation technology is divided into magnetic attraction type magnetic levitation and magnetic repulsion type magnetic levitation. The birth and development of magnetic levitation technology stems from human beings' pursuit of transportation speed. With the increasing maturity of the application of magnetic levitation technology in the field of transportation and the rapid development of science and technology in my country, the application field of magnetic levitation technology is becoming more and more extensive. In daily life, the principle of magnetic levitation can also be used to achieve contactless suspension or movement of some objects.

[0003] However, most of the current magnetic levitation devices can only suspend objects at a fixed height above a suspension base, and cannot drive the object to dynamically change the suspension height during operation. Some products install a moving device under the magnetic levitation device, and use the moving device to drive the magnetic levitation device to move, thereby driving the suspended object suspended by the magnetic levitation device to move. However, the moving device itself is large in size, which will increase the overall volume of the product on the one hand, and increase the production cost of the product on the other. Summary of the invention

[0004] The object of the present invention is to provide a magnetic repulsion type magnetic suspension device which has a simple structure, low production cost and is conducive to miniaturized production of products.

[0005] The technical solution of a magnetic repulsion type magnetic suspension device disclosed in the present invention is:

[0006] A magnetic repulsion type magnetic suspension device comprises a ring-like magnet supply component for providing a first magnetic force, a suspension body for providing a second magnetic force, and a balanced magnet supply component for providing a balancing force for the suspension body in a horizontal direction.

[0007] A suspension area for suspending the suspended body is formed on the axis of the quasi-annular magnet supply component. The quasi-annular magnet supply component can adjust the position of the suspension area by changing its own equivalent diameter, thereby adjusting the suspension position of the suspended body.

[0008] As a preferred embodiment, the annular magnet supply component includes permanent magnets and / or electromagnets, and the multiple permanent magnets and / or electromagnets contained in the annular magnet supply component are distributed in inner and outer rings or in upper and lower rings.

[0009] As a preferred solution, a movable component is also included, and the movable component is used to drive the annular magnet supply component to shrink inward or spread outward, thereby changing the equivalent diameter of the annular magnet supply component.

[0010] As a preferred embodiment, the movable component includes a first movable part and a second movable part. The first movable part and the second movable part can rotate relative to each other. The relative rotation between the first movable part and the second movable part can drive the annular magnet supply component to contract inward or spread outward.

[0011] As a preferred solution, the movable assembly further includes a first driving device, and the first driving device is used to drive the first movable member and the second movable member to rotate relative to each other.

[0012] As a preferred solution, the second movable member comprises a storage box, the storage box houses the first movable member, and the first movable member is rotatable in the storage box.

[0013] As a preferred solution, a second driving device is installed on the storage box, and the second driving device is used to drive the first movable part to rotate, thereby driving the annular magnet supply component to shrink inward or spread outward.

[0014] As a preferred solution, the storage box includes an upper shell, and the storage box also includes a lower shell fixedly mounted to the upper shell via a detachable structure, and the first movable member is installed between the upper shell and the lower shell and can rotate.

[0015] As a preferred embodiment, the movable component also includes a moving part, on which the annular magnetization component is mounted, and the moving part is driven to move, thereby driving the annular magnetization component to contract inward or spread outward.

[0016] As a preferred solution, the balanced magnet supply component includes at least one electromagnet installed below the suspension, and the electromagnet of the balanced magnet supply component is controlled by a control component, and the control component receives information fed back by a sensor component to control the electromagnet of the balanced magnet supply component.

[0017] The magnetic repulsion type magnetic suspension device provided by the present invention comprises a ring-like magnet supply component, a balanced magnet supply component and a suspension body. In the suspension area, the second magnetic force generated by the suspension body and its own gravity offset the first magnetic force generated by the ring-like magnet supply component, and the suspension body is in a suspended equilibrium state. When the equivalent diameter of the ring-like magnet supply component changes, the distribution state of the magnetic field around the ring-like magnet supply component changes, thereby causing the position of the suspension area to change, and the suspended equilibrium state of the suspension body is broken until the suspension body moves to a new suspension area and is in a suspended equilibrium state again. The present invention adjusts the position of the suspension area by changing the equivalent diameter of the ring-like magnet supply component, thereby realizing the position adjustment of the suspension body, thereby realizing the height adjustment of the suspension body. Compared with adding a moving device to move the entire ring-like magnet supply component, it not only simplifies the product structure and reduces the volume, but also facilitates the miniaturization and thinning of the product, saving production costs.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0029] Embodiment 1

[0030] Please refer to Figure 1 , 2 , Figure 1 is a schematic diagram of the magnetic field distribution state of the magnetic repulsion type magnetic suspension device of the present invention, Figure 2 It is a schematic structural diagram of a magnetic repulsion type magnetic suspension device according to the first embodiment of the present invention.

[0031] Embodiment 1 of the present application provides a magnetic repulsion type magnetic levitation device, which includes a ring-shaped magnet supply component 10 for providing a first magnetic force, a suspension body 20 for providing a second magnetic force, and a balanced magnet supply component 30 for providing a balancing force for the suspension body 20 in a horizontal direction.

[0032] A suspension area for suspending the suspension body 20 is formed above the annular magnet supply component 10 . The annular magnet supply component 10 can adjust the magnetic field distribution state by changing the equivalent diameter to adjust the position of the suspension area, thereby adjusting the suspension position of the suspension body 20 .

[0033] In this embodiment, the magnetic repulsion type magnetic suspension device provided by the present invention includes a ring-like magnet supply component, a balanced magnet supply component and a suspension body. In the suspension area, the second magnetic force generated by the suspension body and its own gravity offset the first magnetic force generated by the ring-like magnet supply component, and the suspension body is in a suspended equilibrium state. When the equivalent diameter of the ring-like magnet supply component changes, the distribution state of the magnetic field around the ring-like magnet supply component changes, thereby causing the position of the suspension area to change, and the suspension balance state of the suspension body is broken until the suspension body moves to a new suspension area and the suspension body is in a suspended equilibrium state again. The present invention adjusts the position of the suspension area by changing the equivalent diameter of the ring-like magnet supply component, realizes the position adjustment of the suspension body, and thus realizes the height adjustment of the suspension body. Compared with adding a moving device to move the entire ring-like magnet supply component, it not only simplifies the product structure and reduces the volume, but also facilitates the miniaturization and thinning of the product, saving production costs.

[0034] Furthermore, the balanced magnet supply component 30 includes at least one electromagnet installed below the suspension 20 . The electromagnet of the balanced magnet supply component 30 is controlled by a control component. The control component receives information fed back by a sensor component to control the electromagnet of the balanced magnet supply component 30 .

[0035] It is understandable that in the magnetic repulsion type magnetic suspension device provided by the present invention, the control component is used to receive the information fed back by the sensor component, the control component is used to control the power on or off of the electromagnet, and the control component is also used to control other components or devices of the device such as the drive device. The sensor component includes at least one magnetic sensor, which is used to detect the information of the magnetic field in the device and feed it back to the control component. The control component sends a control signal to the balance magnet supply component according to the feedback information, so that the balance magnet supply component cooperates with the annular magnet supply component to stabilize the suspension balance of the suspension body.

[0036] Embodiment 2

[0037] Please refer to 1 and 3. Figure 1 is a schematic diagram of the magnetic field distribution state of the magnetic repulsion type magnetic suspension device of the present invention, Figure 3 It is a structural schematic diagram of a magnetic repulsion type magnetic levitation device according to the second embodiment of the present invention.

[0038] A magnetic repulsion type magnetic levitation device is provided in the second embodiment of the present application. Based on the first embodiment, the annular magnet supply component 10 of the magnetic repulsion type magnetic levitation device of this embodiment includes permanent magnets and / or electromagnets. The multiple permanent magnets and / or electromagnets included in the annular magnet supply component 10 are distributed in an inner and outer ring shape or in an upper and lower ring shape.

[0039] In this embodiment, when the annular magnet supply component 10 includes an inner ring part and an outer ring part, and all of them are composed of electromagnets:

[0040] (1) For the inner ring electromagnet or the outer ring electromagnet of the annular magnet supply component 10, one part is selected to be continuously powered to generate a magnetic field, and the other part is not powered and does not generate a magnetic field. At this time, the magnetic field generated by the powered part is used to suspend the suspended body 20.

[0041] When the position of the suspension 20 needs to be adjusted, power is supplied to another part that is not powered at the beginning, so that it generates a magnetic field. At this time, the magnetic field is the superposition of the magnetic field of the inner circle electromagnet and the magnetic field of the outer circle electromagnet. The superposition of the magnetic fields of the inner circle and the outer circle changes the magnetic field strength of the magnetic field around the quasi-annular magnet supply component 10, and also changes the equivalent diameter of the quasi-annular magnet supply component 10, thereby changing the suspension area. At this time, the magnetic field used for the suspension 20 to suspend is the magnetic field after the superposition of the magnetic field of the inner circle electromagnet and the magnetic field of the outer circle electromagnet.

[0042] (2) The electromagnets in the inner circle and the outer circle of the quasi-annular magnet supply component 10 are powered at the same time to generate a magnetic field. At this time, the magnetic field formed by the electromagnets in the inner circle and the outer circle of the quasi-annular magnet supply component 10 is used to suspend the suspended body 20:

[0043] When the position of the suspension 20 needs to be adjusted, one of the inner and outer electromagnets of the annular magnet supply component 10 is kept powered, and the other is stopped, which changes the magnetic field strength of the magnetic field around the annular magnet supply component 10 and changes the equivalent diameter of the annular magnet supply component 10, thereby changing the suspension area. At this time, the magnetic field generated by the part that continues to be powered is used for the suspension of the suspension 20.

[0044] In this embodiment, when one of the inner ring part and the outer ring part of the annular magnet supply component 10 is composed of a permanent magnet and the other is composed of an electromagnet:

[0045] The magnetic field generated by the part composed of permanent magnets is used to suspend the suspended body 20 and form the initial position of the suspended body 20. The other part composed of electromagnets changes the equivalent diameter of the annular magnet supply component 10 by turning on and off the power, thereby changing the suspension area and moving the suspended body 20 from the initial position.

[0046] It can be understood that in this embodiment, the inner ring part and the outer ring part of the annular magnet supply component 10 can also be composed of a mixture of permanent magnets and electromagnets. Similarly, the magnetic field provided by the permanent magnet component is used to suspend the initial position of the suspension 20, and the position is adjusted by powering on and off the electromagnet part or adjusting the current intensity.

[0047] In addition, according to the prior art, the distance between the suspension area and the center point of the central axis of the quasi-annular magnet supply component is in a nonlinear proportional relationship with the equivalent diameter of the quasi-annular magnet supply component, that is, the larger the equivalent diameter, the farther the suspension area is; under different equivalent diameters, the change in unit equivalent diameter is not proportional to the change in spacing caused by it. Therefore, in this embodiment, when the inner ring part of the quasi-annular magnet supply component is composed of electromagnets, the electromagnets in the inner ring part are energized to increase the magnetic field strength and reduce the overall equivalent diameter, thereby increasing the suspension area.

[0048] Embodiment 3

[0049] Please refer to Figures 4 to 7 , Figure 4 is a schematic structural diagram of a magnetic repulsion type magnetic suspension device according to a third embodiment of the present invention, Figures 5 to 7 All of them are schematic cross-sectional structural diagrams of the magnetic repulsion type magnetic levitation device according to the third embodiment of the present invention.

[0050] Embodiment 3 of the present application provides a magnetic repulsion type magnetic levitation device. Based on Embodiment 2, the magnetic repulsion type magnetic levitation device of this embodiment further includes an active component 40, and the active component 40 is used to drive the annular magnet supply component 10 to contract inward or diffuse outward, thereby changing the equivalent diameter of the annular magnet supply component 10.

[0051] It is understandable that the movable component 40 includes but is not limited to a telescopic device, a rotating device, and a sliding device. In addition, in combination with the second embodiment, the movable component 40 can also only provide a platform for installing the annular magnet supply component 10, and use the characteristics of mutual attraction or repulsion between magnets to achieve the change of the equivalent diameter of the annular magnet supply component 10.

[0052] Furthermore, the movable component 40 includes a first movable part and a second movable part. The first movable part and the second movable part can rotate relative to each other. The relative rotation between the first movable part and the second movable part can drive the annular magnet supply component 10 to shrink inward or spread outward.

[0053] Furthermore, the movable assembly 40 also includes a first driving device, and the first driving device is used to drive the first movable member and the second movable member to rotate relative to each other.

[0054] It is understandable that the driving device of the present invention includes but is not limited to human drive, electric drive, hydraulic drive or pneumatic drive.

[0055] In this embodiment, the annular magnet supply component 10 is driven by the movable component 40 to move, so that the multiple electromagnets and / or permanent magnets included in the annular magnet supply component 10 can keep moving synchronously, which is more conducive to accurately controlling the suspension of the suspension body 20. In addition, the annular magnet supply component 10 can be adjusted to different distribution states.

[0056] It should be noted that, when the permanent magnets and / or electromagnets of the quasi-annular magnet supply component are distributed in inner and outer rings, the movable component changes the equivalent diameter of the quasi-annular magnet supply component and adjusts the magnetic field distribution state around the quasi-annular magnet supply component by moving the permanent magnets and / or electromagnets of the quasi-annular magnet supply component, thereby achieving the purpose of adjusting the suspension position; when the permanent magnets and / or electromagnets of the quasi-annular magnet supply component are combined with upper and lower ring distributions and inner and outer ring distributions, the quasi-annular magnet supply component and the movable component can cooperate to achieve a variety of adjustment methods, and the implementation methods are diversified.

[0057] Embodiment 4

[0058] Please refer to Figure 8 , 9 , Figure 8 is a schematic structural diagram of a magnetic repulsion type magnetic suspension device according to a fourth embodiment of the present invention, Fig. 9It is a schematic diagram of the cross-sectional structure of the magnetic repulsion type magnetic levitation device of the fourth embodiment of the present invention.

[0059] Embodiment 4 of the present application provides a magnetic repulsion type magnetic levitation device. Based on embodiment 2, the magnetic repulsion type magnetic levitation device of this embodiment further includes an active component 40, and the active component 40 is used to drive the annular magnet supply component 10 to contract inward or diffuse outward, thereby changing the equivalent diameter of the annular magnet supply component 10.

[0060] It is understandable that the movable component 40 includes but is not limited to a telescopic device, a rotating device, and a sliding device. In addition, in combination with the second embodiment, the movable component 40 can also only provide a platform for installing the annular magnet supply component 10, and use the characteristics of mutual attraction or repulsion between magnets to achieve the change of the equivalent diameter of the annular magnet supply component 10.

[0061] Furthermore, the movable component 40 includes a first movable part and a second movable part. The first movable part and the second movable part can rotate relative to each other. The second movable part includes a storage box. The storage box contains the first movable part. The first movable part can rotate inside the storage box.

[0062] Furthermore, a second driving device is installed on the storage box, and the second driving device is used to drive the first movable part to rotate, thereby driving the annular magnet supply component 10 to shrink inward or spread outward.

[0063] It is understandable that the driving device of the present invention includes but is not limited to human drive, electric drive, hydraulic drive or pneumatic drive.

[0064] Furthermore, the storage box includes an upper shell, and the storage box also includes a lower shell fixedly mounted with the upper shell via a detachable structure, and the first movable member is installed between the upper shell and the lower shell and can rotate.

[0065] In this embodiment, the annular magnet supply assembly is driven to move by the movable assembly, and the movable assembly installs the annular magnet supply assembly in the form of a storage box. On the one hand, it is beneficial to the overall production and installation, and on the other hand, it can prevent the external environment from affecting the internal annular magnet supply assembly and other parts.

[0066] Embodiment 5

[0067] Please refer to Figure 7 , 9 , Figure 7 is a schematic structural diagram of a magnetic repulsion type magnetic suspension device according to a third embodiment of the present invention, Fig. 9 It is a structural schematic diagram of a magnetic repulsion type magnetic levitation device according to a fourth embodiment of the present invention.

[0068] Embodiment 5 of the present application provides a magnetic repulsion type magnetic levitation device. Based on embodiment 3 or embodiment 4, the active component 40 of the magnetic repulsion type magnetic levitation device of this embodiment also includes a moving part, on which the annular magnetization component 10 is mounted. The moving part is driven to move, thereby driving the annular magnetization component 10 to contract inward or spread outward.

[0069] On the basis of the third embodiment, the first movable part and the second movable part rotate relative to each other, driving the movable part to move, thereby driving the annular magnet supply component 10 on the movable part to move, contract inward or spread outward, thereby realizing the change of the equivalent diameter of the annular magnet supply component 10, and then adjusting the suspension area.

[0070] It can be understood that tracks for displacement of the movable members may be provided on the first movable member and the second movable member, so that the movable members can be displaced according to preset tracks.

[0071] On the basis of the fourth embodiment, the first movable part rotates between the upper shell and the lower shell of the storage box, driving the movable part to move, thereby driving the annular magnet supply component 10 on the movable part to move, contract inward or spread outward, thereby realizing the change of the equivalent diameter of the annular magnet supply component 10, and then adjusting the suspension area.

[0072] It can be understood that the first movable member and the upper shell, lower shell and upper shell of the storage box are provided with tracks for displacement of the movable member, so that the movable member is displaced according to the preset track.

[0073] In the present embodiment, it is effectively avoided that the movable component directly drives the annular magnet supply component to move, and the permanent magnet and / or electromagnet of the annular magnet supply component directly contacts the movable component, causing the permanent magnet and / or electromagnet of the annular magnet supply component to be damaged, and the setting of the movable part increases the service life cycle. In addition, when the movable part and the permanent magnet and / or electromagnet of the annular magnet supply component are detachably installed, it is convenient for replacement and maintenance without disassembling the entire movable component. The present invention can select to set the movable part to move the annular movable component according to actual needs, or directly move the annular movable component.

[0074] Embodiment 6

[0075] Please refer again Figure 1 Embodiment 6 of the present application provides a magnetic repulsion type magnetic levitation device. Based on the above embodiments 1 to 5, the balanced magnetization component 30 of this embodiment includes at least one electromagnet installed under the suspension 20. The electromagnet of the balanced magnetization component 30 is controlled by a control component and driven by an independent power supply. The control component receives information fed back by a sensor component to control the electromagnet of the balanced magnetization component 30.

[0076] Furthermore, the electromagnet of the balanced magnet supply assembly 30 is installed below the suspension 20 through a moving assembly.

[0077] It can be understood that the electromagnets in the present invention can be driven independently, and the power supply time, rate and size can be adjusted according to actual conditions. The electromagnets in the balanced magnetic supply component 30 include at least two groups, each group can be connected in series or in parallel, and can also be driven individually.

[0078] Understandably, the balanced magnet supply component 30 can be installed in the device through a moving component, and can be moved as a whole, or the electromagnet of the balanced magnet supply component 30 can be moved individually. When the position of the suspension 20 changes, such as the suspension height becomes higher, the balancing ability of the electromagnet of the balanced magnet supply component 30 on the suspension 20 decreases, and the position of the electromagnet of the balanced magnet supply component 30 can be adjusted through the moving component to increase the force of the electromagnet of the balanced magnet supply component 30 on the suspension 20, thereby improving the balancing ability of the balanced magnet supply component 30 on the suspension 20.

[0079] It should be noted that in all the above embodiments, the quasi-annular magnetization component is composed of at least one electromagnet and / or permanent magnet, and its distribution, whether it is an upper and lower annular distribution or an inner and outer annular distribution, ultimately forms a shape similar to an annular shape. The magnetic field distribution characteristics of the quasi-annular magnetization component determine that there is an area on its central axis, and the magnetic potential energy of the intersection point on the plane perpendicular to the central axis at any point through the area is the lowest, and this area is the suspension area. According to the prior art, the distance between the suspension area and the center point of the central axis of the quasi-annular magnetization component is in a nonlinear proportional relationship with the equivalent diameter of the quasi-annular magnetization component, that is: the larger the equivalent diameter, the farther the suspension area; under different equivalent diameters, the change in unit equivalent diameter is not proportional to the change in spacing caused by it. Utilizing this feature, the present invention can be set according to actual needs, so that the movable component retracts the quasi-annular magnetization component inward to drive the suspended body to rise, or the movable component retracts the quasi-annular magnetization component inward to drive the suspended body to fall, and vice versa.

[0080] The control component of the present invention can be a circuit board installed on the first movable part or the storage box, which adjusts the magnetic field strength and polarity of the electromagnet of the balanced magnet supply component by receiving the magnetic field change sensed by the magnetic sensor and adjusting the current intensity and direction of the electromagnet of the balanced magnet supply component, thereby maintaining the suspension and balance of the suspended body. In addition, when the ring-shaped magnet supply component includes an electromagnet, the control component can also control the current change of the electromagnet of the ring-shaped magnet supply component, control the direction and size of its current, and thus change the direction and strength of the magnetism of the electromagnet.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
