The utility model provides a controllable rotatory magnetic suspension device.
In the embodiment of the present invention, referring to fig. 1, fig. 2 and fig. 6, the magnetic suspension apparatus 1 capable of controlled rotation includes:
A magnetic base 10;
The levitation assembly 20 comprises a magnetic levitation body 220, the magnetic levitation body 220 is used for carrying a non-magnetic levitation object 210 to be levitated, and when the levitation assembly 20 is in a levitated state, the gravity of the levitation assembly 20 is balanced by the magnetic force generated between the magnetic base 10 and the magnetic levitation body 220, so that a preset distance is kept between the magnetic levitation body 220 and the magnetic base 10; and
The positioning assembly 30 includes a first positioning element 310 and a second positioning element 320, the first positioning element 310 is disposed on the magnetic base 10, the second positioning element 320 is disposed on the magnetic suspension body 220, and the first positioning element 310 and the second positioning element 320 limit the magnetic suspension body 220 to rotate relative to the magnetic base 10 through magnetic adsorption in a working state.
Specifically, a magnetic levitation system composed of a permanent magnet and an electromagnetic coil is provided in the magnetic base 10. In order to ensure the suspension stability of the magnetic suspension body 220, the magnetic suspension body 220 should have stable magnetism, and the magnetic suspension body 220 is preferably a permanent magnet, although in some other embodiments, the magnetic suspension body 220 can also be realized by the structure of an electromagnetic coil. The permanent magnet can be made of ferrite permanent magnet materials, aluminum-nickel-cobalt permanent magnet alloy materials, iron-chromium-cobalt permanent magnet alloy materials, samarium-cobalt (SmCo) permanent magnet materials, neodymium-iron-boron (NdFeB) permanent magnet materials and the like.
it can be understood that when the to-be-suspended matter 210 is placed on the magnetic suspension body 220, the gravity of the suspension assembly 20 is the combination of the gravity of the to-be-suspended matter 210 and the gravity of the magnetic suspension body 220, and at this time, the magnetic force between the magnetic suspension body 220 and the magnetic base 10 is balanced with the gravity of the suspension assembly 20 (the combination of the gravity of the to-be-suspended matter 210 and the gravity of the magnetic suspension body 220), so that the magnetic suspension body 220 and the to-be-suspended matter 210 achieve the suspension effect; when the object to be suspended 210 is not placed on the magnetic suspension 220, the gravity of the suspension assembly 20 only includes the gravity of the magnetic suspension 220, and the magnetic force between the magnetic suspension 220 and the magnetic base 10 and the gravity of the magnetic suspension 220 are balanced.
It should be noted that the suspension assembly 20 may be suspended above the magnetic base 10, or the suspension assembly 20 may be suspended below the magnetic base 10. Referring to fig. 1 and 2, when the levitation assembly 20 is levitated above the magnetic base 10, the magnetic levitation system in the magnetic base 10 has the same magnetic properties as the magnetic levitation body 220, i.e., a magnetic repulsive force is generated between the magnetic base 10 and the magnetic levitation body 220, which is balanced with the gravity of the levitation assembly 20. Referring to fig. 6, when the levitation assembly 20 is levitated below the magnetic base 10, the magnetic levitation system within the magnetic base 10 is opposite in magnetism to the magnetic levitation body 220, i.e., a magnetic attraction force is generated between the magnetic base 10 and the magnetic levitation body 220, which is balanced with the gravity of the levitation assembly 20. In addition, in the case that the levitation assembly 20 is suspended above the magnetic base 10, when the levitation assembly 20 comprises the to-be-levitated object 210 and the magnetic levitation body 220, the to-be-levitated object 210 can be directly placed on the upper side of the magnetic levitation body 220; in the embodiment where the levitation assembly 20 is levitated below the magnetic base 10, when the levitation assembly 20 comprises the to-be-levitated object 210 and the magnetic levitation body 220, the to-be-levitated object 210 is located on the lower side surface of the magnetic levitation body 220, and in order to prevent the to-be-levitated object 210 from being separated from the magnetic levitation body 220, the to-be-levitated object may be fixed on the magnetic levitation body 220 by gluing, welding, or the like, or may be detachably connected to the magnetic levitation body.
the suspension object 210 to be suspended can be a camera, a globe, a sound box or a luminous element, etc., and the suspension effect is realized through the controllable rotating magnetic suspension device 1.
the gravity of the levitating assembly 20 is balanced by the magnetic force generated between the magnetic base 10 and the magnetic levitating body 220, and the levitating assembly 20 can freely rotate relative to the magnetic base 10 under any external force, so that the rotation of the levitating assembly 20 relative to the magnetic base 10 is uncontrollable. In order to avoid the rotation of the levitation assembly 20 relative to the magnetic base 10, in the present embodiment, the magnetic levitation device 1 capable of controlled rotation further includes a positioning assembly 30, the positioning assembly 30 includes a first positioning element 310 and a second positioning element 320 capable of generating a magnetic attraction force with each other, wherein the first positioning element 310 and the second positioning element 320 are installed on the magnetic base 10 and the magnetic levitation body 220 in a one-to-one correspondence manner, that is, the magnetic attraction force of the positioning assembly 30 restricts the rotation of the magnetic levitation body 220, thereby achieving the positioning levitation effect of the levitation assembly 20.
the utility model discloses technical scheme adds locating component 30 through adopting at controllable rotatory magnetic suspension device 1, wherein, first setting element 310 is installed on magnetic base 10, second setting element 320 is installed on magnetic suspension body 220, first setting element 310 and second setting element 320 produce the magnetic adsorption power of inter attraction downwards at operating condition, thereby retrain the rotation of magnetic suspension body 220 through this magnetic adsorption power, the free rotation of suspension subassembly 20 relative magnetic base 10 has been avoided, thereby the location suspension effect of suspension subassembly 20 has been realized.
Further, there are various ways to realize the above-mentioned positioning assembly 30, as long as the magnetic attraction force between the first positioning member 310 and the second positioning member 320 can be realized, and is not limited in detail herein. For example, in some embodiments, the first positioning member 310 may be an electromagnet and/or a permanent magnet; likewise, the second positioning member 320 may be an electromagnet and/or a permanent magnet.

In this way, the magnetic attraction force generated between the first positioning member 310 and the second positioning member 320 is relatively far away from the rotation axis of the magnetic suspension body 220, and the magnetic attraction force generates a large torque on the magnetic suspension body 220, so that the rotation of the magnetic suspension body 220 is more easily restricted.

The magnetic repulsion force generated between the magnetic base 10 and the magnetic suspension body 220 is balanced with the gravity of the suspension assembly 20, so that the suspension assembly 20 is suspended above the magnetic base 10.
In some scenarios, controllable rotation of the object to be suspended 210 relative to the magnetic base 10 is often required, for example, controllable rotation of a camera through 360 degrees, controllable rotation of a model of a mobile phone, etc. Further, in order to realize the controllable rotation of the to-be-suspended object 210, the suspension assembly 20 further includes a rotating member 230 disposed on a side of the magnetic suspension 220 opposite to the magnetic base 10, the rotating member 230 has a fixed portion and a rotating portion capable of rotating relative to the fixed portion, the rotating portion is disposed on a side of the fixed portion opposite to the magnetic suspension 220, the fixed portion is fixedly connected with the magnetic suspension 220, and the rotating portion is configured to support the to-be-suspended object 210, so that the to-be-suspended object 210 rotates relative to the magnetic suspension 220. The rotating member 230 can be controllably rotated, so that the object to be suspended 210 can be controllably rotated with respect to the magnetic suspension 220, that is, the object to be suspended 210 can be controllably rotated with respect to the magnetic base 10.
Further, the rotating member 230 may be a motor, a stator of the motor is connected to the fixed portion, and a rotor of the motor is connected to the rotating portion. The rotating member 230 is preferably a stepper motor so that the angle of rotation of the magnetic suspension 220 relative to the material 210 to be suspended can be more accurately controlled. Of course, in other embodiments, the rotating member 230 can be implemented by other controllable rotating devices, and is not limited herein.
further, referring to fig. 1 and fig. 2, and with reference to fig. 5, for the above-mentioned controllable rotating magnetic levitation apparatus 1, the magnetic levitation apparatus further includes a wireless power supply module 40, the wireless power supply module 40 includes a power transmission coil 410 and a power receiving coil 420, the power transmission coil 410 is disposed on the magnetic base 10, the power receiving coil 420 is disposed on the magnetic levitation body 220, the power transmission coil 410 is connected to a power source, and the power receiving coil 420 is electrically connected to the above-mentioned motor, so as to energize the motor to work, thereby realizing controllable rotation of the to-be-levitated object 210 relative to the magnetic levitation body 220.
