Detailed Description
The present invention is further described with reference to the following examples and accompanying drawings, which are included to provide a further understanding of the invention, and are not intended to limit the invention.
The specific structure and operation of the magnetic levitation device of the present invention can be seen in the applicant's prior patent CN1819436B (incorporated herein by reference in its entirety), which includes a base module (also referred to as "base" or "base") and a suspension body, such as a globe, capable of stably suspending above it. The basic module and the suspension body are respectively provided with magnetic components which can interact to provide static balance magnetic fields, and a controller and other related electromagnetic elements and the like are also arranged in the basic module or the base to control the suspension body to be in a balance suspension position relative to the base in real time.
Fig. 1 shows a schematic perspective view of a magnetic levitation apparatus according to the present invention, which includes a base B and a levitation body F suspended above the base B. The suspension F is provided with, for example, a cylindrical magnet m. The base B has therein a rotary lifting mechanism 1 and a base module 3. The upper surface of the base B is also provided with a positioning projection p for initially positioning the suspension body F, for example, projecting into a correspondingly provided recess on the suspension body F.
Fig. 2 is a schematic cross-sectional view of a base B of the magnetic levitation apparatus shown in fig. 1 with a housing removed. As shown more clearly in fig. 2, the rotary lifting mechanism 1 of the present invention includes a fixed base 10 and a movable bracket 20. The base module 3 is provided on the movable support 20, and includes a circuit board 30, a ring magnet 31, and an electromagnetic coil 32, and a controller and the like, which are not shown.
The holder 10 is formed of a bottom plate 110 and a top plate 111 spaced in parallel. The top plate 111 is fixedly provided with an internal thread fixed cylinder 12 and a cylindrical rotating body or rotating cylinder 13 which is rotatably arranged, and the rotating cylinder 13 is positioned inside the internal thread fixed cylinder 12. Although the lower portion of the internally threaded stator 12 is shown as not being threaded, it may be threaded along its entire length.
As shown, the lower end of the rotary cylinder 13 is fitted with a gear 16 by means of a fastener in the form of a screw. A bidirectional motor 14 is also mounted on the top plate 111, a gear 15 is also mounted on the rotating shaft of the motor 14 through a fastener in the form of a screw, and the gear 15 is engaged with the gear 16.
The movable holder 20 is composed of a top plate 21 and a male screw cylinder 22 fixed to the top plate 21. The top 21 is used for fixedly mounting the base module 3. The external thread moving cylinder 22 is inserted between the internal thread fixed cylinder 12 and the rotary cylinder 13, and forms a thread matching connection with the internal thread fixed cylinder 12 on one hand, and forms an integrally rotatable but vertically slidable connection with the rotary cylinder 13 through the rotation limiting block 130 protruding into the sliding groove 220 therein on the other hand. Thus, when the motor 14 drives the gear 15 to rotate, the gear 15 drives the gear 16 and further drives the rotary cylinder 13 to rotate together, the rotary cylinder 13 drives the external thread moving cylinder 22 to rotate, the external thread moving cylinder 22 rotates relative to the internal thread fixed cylinder 12 and slides up and down relative to the rotary cylinder 13 by means of the thread matching effect of the two, and finally the rotary type ascending or descending of the whole movable support 20 relative to the fixed seat 10 is realized.
Due to the integral rotary ascending of the movable support 20 and the base module 3 thereon, the suspension body F can be automatically in a rotary state (the rotary state can be in a convenient viewing situation without manually handling the suspension body 6) at the moment of separating from the base B (at this time, the distance between the suspension body F and the base module 3 is just the set suspension height when the suspension body stably suspends relative to the base module). For example, if the movable frame 20 and the base module 3 rise clockwise, the suspension body F is automatically suspended in a clockwise rotation state.
As shown in fig. 2, an electrical slip ring or a slip ring is further mounted on the bottom plate 110 of the fixing base 10. The electrical slip ring has a stator 17 and a rotor 18, and the rotor 18 is connected to the circuit board 30 of the base module 3 through an upper and lower through hole formed in the rotary cylinder 13 by a wire 180, and the stator 17 is connected to an external power source through a wire.
Due to the arrangement of the electric slip ring, the problem of wire twisting caused by relative rotation between the electric wire for supplying power to the circuit board 30 of the base module 3 on the movable support 20 and an external fixed power supply can be effectively avoided.
As an alternative to the embodiment shown in fig. 2, it is also possible to dispose the rotary cylinder 13 at the outermost side, while disposing the internal threaded stationary cylinder 12 at the innermost side instead of the external threaded stationary cylinder, and disposing the external threaded movable cylinder 22 still therebetween instead of the internal threaded movable cylinder. This also enables the rotary raising effect of the movable bracket 20 of the present invention.
Although in the embodiment shown in fig. 1 the base module 3 of the magnetic levitation apparatus and the rotary lifting mechanism 1 are integrally enclosed in a base B, the base B may be eliminated according to the application as long as the suspension body F can be initially positioned relative to the base module 3 along the levitation vertical line to a non-levitation state above the set levitation height.
It will be understood by those skilled in the art that the various directional terms described above, including "upper", "lower", etc., are used only in conjunction with the embodiments shown in the drawings and are not intended to limit the invention.
