The utility model provides a controllable rotatory magnetism type magnetic suspension device of inhaling.
In an embodiment of the present invention, referring to fig. 1 to 3, the magnetic suspension apparatus 1 includes:
a magnetic base 10;
a magnetic suspension member 20 generating a magnetic attraction force with the magnetic base 10 to suspend the magnetic suspension member 20 below the magnetic base 10, the magnetic suspension member 20 being horizontally rotatable about a first axis with respect to the magnetic base 10; and
the rotary driving part 30 is positioned at the lower side of the magnetic suspension part 20 and is rotationally connected with the magnetic suspension part 20, and the rotary driving part 30 horizontally rotates around the first axis relative to the magnetic suspension part 20;

Specifically, the magnetic base 10 has magnetism, and can generate a magnetic field below the magnetic base 10, and the magnetic suspension member 20 also has magnetism, and when the magnetic suspension member 20 is located at a specific position of the magnetic field above the magnetic base, the magnetic attraction force between the magnetic suspension member 20 and the magnetic base 10 is balanced with the gravity of the magnetic suspension member 20, so that the magnetic suspension member 20 is suspended below the magnetic base 10. In the present embodiment, when the magnetic suspension 20 is suspended below the magnetic base 10, the magnetic suspension 20 can rotate horizontally about the first axis with respect to the magnetism.

It should be noted that both the magnetic suspension 20 and the rotary driving element 30 can achieve the suspension state through the magnetic attraction between the magnetic suspension 20 and the magnetic base 10, and when in the suspension state, it can be known according to the "law of conservation of angular momentum": when one of the rotary driving member 30 and the magnetic suspension member 20 rotates relative to the magnetic base 10, the other rotates in the opposite direction relative to the magnetic base 10.
In the present embodiment, the rotation driving member 30 can be driven to rotate by itself, so that when the rotation driving member 30 rotates, the magnetic suspension member 20 rotates reversely according to the "law of conservation of angular momentum". For example, when the rotary driving element 30 rotates clockwise relative to the magnetic base 10, the magnetic suspension 20 rotates counterclockwise relative to the magnetic base 10.
The utility model discloses technical scheme adopts and add one and magnetic suspension 20 downside at magnetic suspension 20 and rotate the rotary driving piece 30 of being connected, magnetic suspension 20 suspends in magnetic base 10 below with rotary driving piece 30 jointly, when rotary driving piece 30 takes place relative rotation relative magnetic base 10, magnetic suspension 20 then takes place the antiport according to "the law of conservation of angular momentum" and relative magnetic base 10, therefore, can realize magnetic suspension 20 relative magnetic base 10 controllable rotation, and realize rotary driving piece 30 relative magnetic base 10 controllable rotation.
It can be understood that the above-mentioned magnetic levitation device 1 with controllable rotation can be used in the exhibition industry, for example, the object to be exhibited can be fixed on the rotary driving member 30 or the magnetic levitation member 20, on one hand, the "floating" exhibition effect of the object to be exhibited can be achieved, and on the other hand, the object to be exhibited can also rotate relative to the magnetic base 10 along with the rotary driving member 30, or the object to be exhibited can rotate relative to the magnetic base 10 along with the magnetic levitation member 20.
The rotary driving member 30 may be a rotary device with an energy storage device, and the energy storage device provides energy to the rotary device to make the rotary device rotate, for example, a motor with a battery attached to the rotary device itself, and the battery supplies power to the motor to make the motor rotate. Alternatively, the rotary drive member 30 may be powered by an external power supply device. In this embodiment, the rotary driving element 30 is preferably powered by an external power supply device to realize the rotation of the rotary driving element 30 by power supply, and the specific structure is as follows:
with continued reference to fig. 2 and fig. 3, the magnetic levitation device 1 further includes a wireless power supply assembly 40, the wireless power supply assembly 40 includes a transmitting coil 410 and a receiving coil 420, wherein: the transmitting coil 410 is arranged on the lower side surface of the magnetic base 10, and the transmitting coil 410 is electrically connected with a power supply; the receiving coil 420 is disposed on the upper side of the magnetic suspension 20, and the receiving coil 420 is electrically connected to the rotary driving element 30, so that the rotary driving element 30 is powered to rotate. The rotary driving member 30 is preferably a motor, a rotating shaft 320 of the motor is fixedly connected to the magnetic suspension member 20, and the housing 310 of the motor can horizontally rotate relative to the magnetic suspension member 20. When the motor is energized to rotate, the housing 310 of the motor starts to rotate, and the magnetic suspension 20 also starts to rotate according to the "law of conservation of angular momentum" and the direction of rotation is opposite to the direction of rotation of the housing 310.
Further, in this embodiment, the magnetic levitation device 1 further includes a rotation controller for controlling the rotation speed and/or the rotation direction of the motor. It will be appreciated that the rotational state of the motor is controlled by the rotational controller (e.g., acceleration, deceleration, reverse rotation, etc.) to achieve different rotational states of the rotary drive member 30, and thus the rotational state of the magnetic suspension member 20 can also be controlled according to the "law of conservation of angular momentum". For example, when the motor rotates, the housing 310 of the motor rotates clockwise relative to the magnetic base 10, and the magnetic suspension 20 rotates counterclockwise, and the rotation speed of the motor is increased by the rotation controller, so that the rotation speed of the motor housing 310 relative to the magnetic base 10 can be increased, and at this time, the rotation speed of the magnetic suspension 20 relative to the magnetic base 10 is also increased, so as to control the rotary driving element 30 and the magnetic suspension 20 to achieve the effect of accelerating rotation. Similarly, the effect of controlling the rotation of the rotary driving part 30 and the magnetic suspension part 20 to rotate at a reduced speed can also be achieved by reducing the rotation speed of the motor through the rotation controller; similarly, the rotation direction of the motor is changed by the rotation controller, so that the rotation direction of the housing 310 of the motor relative to the magnetic base 10 and the rotation direction of the magnetic suspension 20 relative to the magnetic base 10 can also be adjusted.

Referring to fig. 3 to 5, in the present embodiment, the magnetic suspension 20 includes a mounting seat 210 and a permanent magnet 220, wherein: the mount 210 has a mounting groove 211 opened downward; the permanent magnetic piece 220 is fixed in the mounting groove 211; the receiving coil 420 is provided on the lower side of the mount 210. In this way, the assembly of the magnetic suspension 20 can be facilitated. The permanent magnet piece 220 may be fixed in the mounting groove 211 by gluing, or the permanent magnet piece 220 may be detachably fixed in the mounting groove 211 by means of snap fit, interference fit, or the like.
Further, the magnetic base 10 includes a substrate 120 and a magnetic module 110 disposed on the substrate 120, wherein the magnetic module 110 includes at least one annular permanent magnet and/or an electromagnetic coil. Wherein the magnetism of the magnetic base 10 is derived from the magnetic module 110, the magnetic module 110 can generate a magnetic field for suspending the magnetic suspension 20.
In the present embodiment, the magnetic suspension 20 is preferably disposed in a cylindrical shape, and the geometric axis of the magnetic suspension 20 is disposed coaxially with the first axis. Therefore, the magnetic suspension member 20 is more stable when rotating around the first axis, which is beneficial to increase the rotation stability of the controllable rotating magnetic attraction type magnetic suspension device 1.
