Description

Technical Field

[0001] The present invention relates to a magnetic levitation device. Background Art

[0002] Existing magnetic levitation devices, as disclosed in the inventor's previous patents CN100544183C and CN105790641B, generally include a fixed base and a levitating body, and a levitation system is formed through the interaction of magnetic fields between the base and the levitating body.

[0003] The inventor's PCT patent application WO2016202187A1 discloses a mobile magnetic levitation device, in which the base moves horizontally in a housing to drive the levitating body to make corresponding movements on one side above the housing, or the base moves along a chute provided on the inner surface of the housing to make the levitating body make corresponding movements inside the housing, and the entire content thereof is hereby incorporated by reference. Summary of the Invention

[0004] The object of the present invention is to provide a novel magnetic levitation device, in which the levitating body can orbit around the base like a planet.

[0005] According to the present invention, there is provided a planetary magnetic levitation device, comprising:

[0006] A stellar base having a housing and a magnetic levitation support mechanism, wherein the magnetic levitation support mechanism is at least partially located inside the housing of the stellar base and is movable along a preset orbit near the inner surface of the housing of the stellar base; and

[0007] A planetary levitating body, which forms a corresponding magnetic levitation system with the magnetic levitation support mechanism to always levitate at a corresponding position outside the housing of the stellar base relative to the magnetic levitation support mechanism in the levitation working state.

[0008] According to a specific embodiment of the present invention, the planetary levitating body comprises a permanent magnet with reverse magnetic poles, the magnetic levitation support mechanism includes a substantially annular permanent magnet, an electromagnetic coil, a magnetic sensor and a controller, the annular permanent magnet of the magnetic levitation support mechanism and the permanent magnet of the planetary levitating body form a substantially balanced magnetic field, the magnetic sensor is used to sense in real time the deviation of the suspension balance position of the permanent magnet of the planetary levitating body relative to the annular permanent magnet of the magnetic levitation support mechanism, and the controller controls the current flowing through the electromagnetic coil according to the deviation of the suspension balance position sensed by the magnetic sensor to return the permanent magnet of the planetary levitating body to its relative suspension balance position.

[0009] According to the present invention, the magnetic levitation support mechanism is preferably pivotally connected to the stellar base to rotate around a corresponding pivot axis, and its rotation trajectory forms the preset orbit (imaginary orbit).

[0010] Alternatively, the preset orbit can also be a corresponding annular orbit (solid orbit) provided on the inner surface of the housing of the stellar substrate. In this case, the annular orbit can preferably be any suitable closed-loop orbit such as a circular or elliptical orbit.

[0011] According to another preferred embodiment of the present invention, the stellar substrate further includes a relatively stationary part, and the housing of the stellar substrate is pivotally connected to the relatively stationary part to rotate around a corresponding housing pivot axis. In addition, the magnetic levitation support mechanism can also be pivotally connected to the relatively stationary part to rotate around a corresponding planet pivot axis.

[0012] The housing pivot axis can coincide with the planet pivot axis. For example, both the magnetic levitation support mechanism and the housing are rotatably mounted around the same straight fixed axis. In this case, the housing of the stellar substrate can be configured as, for example, a globe, and the planet suspension can be configured as a satellite that rotates around the equator or latitude of the globe on the outside. Of course, the straight fixed axis can also be designed as a pivot with an adjustable inclination angle.

[0013] The housing pivot axis can also not coincide with the planet pivot axis (for example, form an angle or be parallel to each other), such as being rotatably mounted around different fixed axes or different straight parts of the same crankshaft. In this case, the housing of the stellar substrate can be configured as, for example, a globe, and the planet suspension can be configured as a moon that rotates around the globe in a set plane on the outside.

[0014] According to a further preferred embodiment of the present invention, a first motor is fixedly installed on the relatively stationary part of the stellar substrate. The magnetic levitation support mechanism is pivotally connected to the relatively stationary part through a rotating arm that can rotate around the planet pivot axis. The rotating arm has at least one telecentric end, and at least one magnetic levitation support mechanism is provided at the at least one telecentric end of the rotating arm. The first motor drives the rotating arm to rotate through a reduction drive train. In addition, a second motor is fixedly installed on the relatively stationary part of the stellar substrate. The housing is pivotally connected to the relatively stationary part through a rotating sleeve that can rotate around the housing pivot axis. The second motor drives the rotating sleeve to rotate through a reduction drive train.

[0015] In the above embodiment, the rotating arm preferably has two symmetric telecentric ends, and a magnetic levitation support mechanism is fixed to each through a corresponding fixture or support, thereby enhancing the balance or smooth operation of the device. In this case, the two symmetric telecentric ends of the rotating arm can be symmetrically arranged in the same direction (on the same side of the rotation plane) or symmetrically arranged in the opposite direction (on both sides of the rotation plane). The rotating arm can be either a straight arm or a curved arm.

[0016] According to a further preferred embodiment of the present invention, a slip ring device is further provided on the relatively stationary part of the stellar base. The slip ring device includes an inner stator conductor and an outer slip ring conductor that rotates around the inner stator conductor and makes sliding contact with the inner stator conductor. The outer slip ring conductor rotates integrally with the magnetic levitation support mechanism, while the inner stator conductor is fixed on the relatively stationary part of the stellar base and connected to the power supply line of an external power supply. In this case, the relatively stationary part of the stellar base preferably includes a fixed shaft around which the magnetic levitation support mechanism is rotatably mounted. The fixed shaft can be a hollow shaft or provided with longitudinal grooves for accommodating the power supply line to supply power to at least the magnetic levitation support mechanism.

[0017] According to another preferred embodiment of the present invention, a wireless transmitting power supply coil is further provided on the magnetic levitation support mechanism, and a wireless receiving power supply coil and corresponding electrical appliances are also provided on the planetary levitation body. The wireless transmitting power supply coil of the magnetic levitation support mechanism cooperates with the wireless receiving power supply coil of the planetary levitation body to supply power to the corresponding electrical appliances.

[0018] In the planetary magnetic levitation device according to the present invention, the stellar base can also move along a set orbit or a predetermined route, so as to achieve multiple composite movements.

[0019] In the present invention, the terms "stellar base" and "planetary levitation body" mean that the latter can orbit around the former along a preset orbit such as an annular orbit like a planet and do not make any actual contact with the former during the operation. Both can be of any suitable configuration such as a sphere or an irregular contour body, and both can include or be provided with various electronic or mechanical devices or be designed as toys or display models, etc. The term "housing" constitutes at least part of the outer contour of the stellar base and has a certain thickness in the corresponding area - less than the equilibrium or stable levitation distance of the planetary levitation body relative to the magnetic levitation support mechanism. The term "magnet" includes permanent magnets and electromagnets. "Reverse magnetic poles" mean that the N and S poles of the magnet are located on opposite sides and on the same straight line. "Basically annular permanent magnet" means that the magnetic field formed by it is basically equivalent to the magnetic field formed by a single corresponding circular permanent magnet, and it can be a single permanent magnet or a corresponding combination of multiple permanent magnet monomers. The term "pivotally connected" means a connection in a pivotable or rotatable manner. The term "relatively stationary part" refers to the fixed installation part or fixed seat structure of the stellar base, such as a fixed shaft.

[0020] Those skilled in the art should understand that the magnetic levitation devices according to different embodiments of the present invention can introduce each other's features or combinations of features, unless it is obviously inapplicable.

[0021] The planetary magnetic levitation device of the present invention ingeniously realizes the required revolution of the planetary floating body around the stellar base body (base), and at the same time, it can also realize the rotation of the housing of the stellar base body, such as a spherical shell, along the required predetermined angle. The device has a compact and reasonable structural design, and its multiple rotation effects are completely refreshing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figures 1-3 FIG. is a schematic structural view of a planetary magnetic levitation device according to different embodiments of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described below in conjunction with embodiments and the drawings. Those skilled in the art should understand that the embodiments and the drawings are only for better understanding of the present invention and are not used to make any limitations.

[0024] Figure 1 A planetary magnetic levitation device of the present invention is shown, which includes a stellar base body 1 and a planetary floating body 5 that at least partially rotates around it.

[0025] The stellar base body 1 is provided with a fixed shaft or pivot 7. A fixed disk or mounting bracket 8 is fixedly provided on the pivot 7. The rotating arm 15 is rotatably mounted on the pivot 7 through a bearing structure and is fixedly connected or integrated with a large gear 14 mounted around the pivot 7. The motor 12 is mounted on the mounting bracket 8, and a small gear 13 is mounted on its drive shaft. The small gear 13 meshes with the large gear 14, thereby forming a reduction drive system between the motor 12 and the rotating arm 15.

[0026] One end of the rotating arm 15 is provided with a support or fixture 6. The fixture 6 holds or fixes the magnetic levitation support mechanism 4. The magnetic levitation support mechanism 4 and the floating body 5 are configured to form, for example, such a magnetic repulsion type suspension system or system: the floating body 5 includes a permanent magnet with a reverse magnetic pole, such as a cylindrical permanent magnet (not specifically shown), and the magnetic levitation support mechanism 4 includes a basic ring-shaped permanent magnet, an electromagnetic coil, a magnetic sensor, and a controller. The ring-shaped permanent magnet and the permanent magnet of the floating body 5 can form a basic balanced magnetic field. The magnetic sensor is used to sense in real time the offset of the permanent magnet of the floating body 5 relative to the ring-shaped permanent magnet of the magnetic levitation support mechanism 4. The controller controls the current flowing through the electromagnetic coil according to the offset sensed by the magnetic sensor to return the permanent magnet of the floating body 5 to its relative suspension equilibrium position. The structure and working principle of this magnetic repulsion type suspension system are well known to those skilled in the art. For example, reference can also be made to the applicant's previous patents CN100544183C and CN105790641B, and their entire contents are incorporated herein by reference.

[0027] At the other end of the rotating arm 15, symmetric clamps 6 and a magnetic levitation support mechanism 17 fixed thereto are also installed, so as to be able to symmetrically levitate another levitated body (not shown). Those skilled in the art can understand that the rotating arm 15 may also not have the above-mentioned other end (i.e., form a single-arm structure), in which case one clamp 6 and its magnetic levitation support mechanism 17 can be omitted. Alternatively, the clamp 6 and its magnetic levitation support mechanism 17 at the other end of the rotating arm 15 can also be simply replaced by a counterweight or balance block, so as to still ensure the smooth operation of the entire device.

[0028] As Figure 1 shown, a large gear 11 is also sleeved on the pivot 7 of the stellar base 1. The large gear 11 is rotatably installed on the pivot 7 through a bearing structure. The spherical housing 3 is fixedly connected to the large gear 11. The motor 9 is also installed on the mounting bracket 8, and a small gear 10 is installed on its drive shaft. The small gear 10 meshes with the large gear 11, thus forming a reduction drive system between the motor 9 and the spherical housing 3. Half of the illustrated spherical housing 3 has been removed to expose the various components therein.

[0029] Figure 1 A slip ring device 16 is also provided on the pivot 7 of the stellar base 1 as shown in .

[0030] Figure 2 shown. The slip ring device 16 has an outer slip ring and an inner stator both made of conductors: the outer slip ring rotates integrally with the rotating arm 15, and the inner stator is fixedly arranged at the end of the pivot 7. The pivot 7 can be arranged as a hollow shaft or a shaft provided with longitudinal slots, so that a power supply wire can be accommodated therein to supply power to the inner stator at the end of the pivot 7, the motors 9 and 12 on the mounting bracket 8. The outer slip ring of the slip ring device 16 is connected to the magnetic levitation support mechanism 4 on the clamp 6 through a wire to supply power to it. The slip ring device 16 avoids the phenomenon of wire twisting when the magnetic levitation support mechanism 4 on the clamp 6 rotates.

[0030] Figure 2 shown. The slip ring device 16 has an outer slip ring and an inner stator both made of conductors: the outer slip ring rotates integrally with the rotating arm 15, and the inner stator is fixedly arranged at the end of the pivot 7. The pivot 7 can be arranged as a hollow shaft or a shaft provided with longitudinal slots, so that a power supply wire can be accommodated therein to supply power to the inner stator at the end of the pivot 7, the motors 9 and 12 on the mounting bracket 8. The outer slip ring of the slip ring device 16 is connected to the magnetic levitation support mechanism 4 on the clamp 6 through a wire to supply power to it. The slip ring device 16 avoids the phenomenon of wire twisting when the magnetic levitation support mechanism 4 on the clamp 6 rotates. Figure 1 shown magnetic levitation device, in which only the shape of the rotating arm 15 is changed, and the others are the same as Figure 1 shown in the embodiment. As Figure 2 shown, both ends of the rotating arm 15 are bent upward, so that the rotation plane where the clamp 6 is located is translated upward accordingly. Of course, both ends of the rotating arm 15 can also be bent in different directions, for example, one end is bent upward and the other end is bent downward, so that the rotation plane where the clamp 6 is located is translated in different directions accordingly.

[0031] Figure 3 shown is Figure 1 another variant of the magnetic levitation device shown, in which only the shape of the pivot 7 is changed, that is, from Figure 1 the straight shaft shown becomes a crankshaft, and the others are the same as Figure 1The embodiment shown. As shown in Fig. 3, the pivot 7 is a crankshaft, where the spherical housing 3 and the upper crankshaft segment around which the rotating arm 15 rotates are not parallel or form an angle with respect to the lower crankshaft segment around which it rotates. Thus, an angle is correspondingly formed between the common rotation axis of the suspension body 5 and the self-rotation axis of the spherical housing 3. In Figure 3 the motor 9 can also be fixedly arranged relative to the pivot 7 through other fixed disks or mounting brackets, that is, it does not need to be fixed on the mounting bracket 8.

[0032] Figures 1-3 In the embodiment shown, the rotating arm 15 can also have three or more ends with clamps 6 mounted thereon, or the rotating arm 15 itself can also be multiple rotating arms with the same or different rotation modes. Thus, multiple planetary suspension bodies 5 can be suspended around the stellar substrate 1 or its spherical housing 3.

[0033] Figure 3 In the embodiment shown, the spherical housing 3 can be configured as a solar model, and the suspension body 5 can be configured as a planetary model, or the spherical housing 3 can be configured as an Earth model or a globe while the suspension body 5 is configured as a satellite or moon model. Thus, the suspension body 5 can rotate around the spherical housing 3 along its predetermined orbit, while the spherical housing 3 can rotate around its predetermined rotation axis. Additionally, the entire stellar substrate 1 can also be placed on a set sliding orbit or rotating orbit to achieve corresponding movements. For example, the spherical housing 3 is configured as a globe, the substrate 1 is placed on an elliptical motion orbit around a central solar model (luminous sphere) and moves accordingly, and the suspension body 5, as a moon model, orbits around the spherical housing 3 while the spherical housing 3 rotates, thus perfectly simulating the relative motion relationship among the sun, the Earth, and the moon.

[0034] Finally, although not specifically shown, the magnetic suspension support mechanism 4 of the present invention can also be additionally provided with a wireless transmitting power supply coil, and the suspension body 5 can also be additionally provided with a wireless receiving power supply coil and corresponding electrical appliances such as light bulbs. The wireless transmitting power supply coil and the wireless receiving power supply coil cooperate to supply power to the electrical appliances of the suspension body 5. This wireless power supply technology is known to those skilled in the art, and its structure and working principle will not be described in detail herein.

[0035] Those skilled in the art should understand that the above embodiments only serve to explain the present invention and should not be construed as any limitation thereto.
