[0001] The utility model belongs to the technical field of scientific teaching aids, in particular to a scientific teaching aid structure for electromagnetic levitation. Background Technique

[0002] Teaching aids refer to models, physical objects, specimens, instruments, charts, slides, etc. used to explain and illustrate something. With the development of natural science, there are various existing scientific teaching aids, including teaching equipment, teaching instruments, training equipment, educational equipment, experimental equipment, teaching specimens, teaching models, etc. However, there is a great lack in terms of natural science teaching aids. For example, there are no scientific teaching aids for wireless charging. In view of this, a scientific teaching aid for electromagnetic levitation is designed to develop children's intelligence and exploration ability, and further stimulate and improve children's interest in learning.

[0003] For example, a printing roller driven by electromagnetic levitation with the publication number CN221250133U. Most of the existing applications of electromagnetic levitation are directly applied to the device structures in life, which are not convenient for children to observe, cannot arouse children's interest and exploration desire, and are not suitable as teaching aids. Content of the Utility Model

[0004] The purpose of the utility model is to provide a scientific teaching aid structure for electromagnetic levitation to solve the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a scientific teaching aid structure for electromagnetic levitation, including a fixing plate, a power supply is arranged on the fixing plate, and a coil support bottom plate and a coil support top plate are arranged on one side of the fixing plate. A central limiting tube is arranged between the coil support bottom plate and the coil support top plate, and a coil roller is fitted on the outer periphery of one end of the central limiting tube. An inductor coil is wound around the outer circle of the coil roller, and a magnetic ring is arranged on one side of the inductor coil. The magnetic ring is designed to be hollow, and the magnetic ring and the outer periphery of the central limiting tube are designed for limiting sliding.

[0006] In a further embodiment, a display screen is embedded and installed on the fixing plate, and the power supply is electrically connected to the display screen and the coil part.

[0007] In a further embodiment, a magnetic ring protection pad is arranged between the magnetic ring and the inductor coil, and the magnetic ring protection pad and the central limiting tube are designed to be slidable.

[0008] In a further embodiment, annular grooves are formed on the outer edges of the coil support bottom plate and the coil support top plate, and a protective transparent cover for protecting the coil part is arranged between the two annular grooves.

[0009] In a further embodiment, the central regions of the coil support base plate and the coil support top plate are recessed and a central convex column is provided at the center point. The central convex column is adapted to the central limiting tube and limits it.

[0010] In a further embodiment, the outer periphery of the coil support base plate and the coil support top plate is provided with protruding portions, and two pin cavities for easy fixing are provided through the protruding portions.

[0011] In a further embodiment, the power supply is an external battery and is controlled by a switch.

[0012] In a further embodiment, the power supply is a hand-cranked power generation part, and power is generated by rotating the hand-cranked handle.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] The hand-cranked handle and the hand-cranked power generation part realize power supply. The coil part generates a magnetic field due to inductance. The magnetic field repels the magnetism generated by the magnetic ring, enabling the magnetic ring to jump, further realizing electromagnetic suspension. The process drives the magnetic ring to jump through hand-cranking, which is highly interesting, can stimulate children's fun and curiosity, and plays an enlightening and educational role.

[0015] The design of the central limiting tube can restrain the coil roller, the magnetic ring, and the magnetic ring protection pad, and can generate a stable limiting effect, making its jumping more stable. The design of the magnetic ring protection pad can play a protective role when the magnetic ring falls, extend the service life, and the protective transparent cover can play a protective role to avoid direct external collision damage.

[0016] This scientific teaching aid structure of electromagnetic suspension intuitively demonstrates electromagnetic suspension in an interesting way, can arouse children's curiosity and exploratory spirit, and enhance their learning interest. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0027] Although there are many existing teaching aids, there is a great lack in the aspect of scientific teaching aids. In order to fill the gap in this field, a scientific teaching aid that can directly demonstrate electromagnetic levitation and has a simple structure and interesting operation is designed. The specific structure is as follows.

[0028] Please refer to Figures 1 to 4 , the structure of the scientific teaching aid for electromagnetic levitation includes a fixed plate 1 and a display screen 2. On one side of the fixed plate 1, there are a bottom plate 4 of the coil support and a top plate 5 of the coil support. The outer periphery of the bottom plate 4 of the coil support and the top plate 5 of the coil support is provided with protruding parts, and two pin cavities 15 for fixing are provided through the protruding parts. The pin cavities 15 are fixed by fixing pins;

[0029] The central regions of the coil support base plate 4 and the coil support top plate 5 are recessed, and a central convex column 12 is provided at the center point. A central limiting tube 6 is arranged between the two central convex columns 12. The outer periphery of the central convex column 12 is adapted to the inner circle of the central limiting tube 6. One end of the outer periphery of the central limiting tube 6 is adapted to a coil roller 7, and an inductor coil 8 is wound around the outer circle of the coil roller 7. A lead wire groove 14 is provided at the center of one side of the coil support base plate 4, and the lead wire groove 14 facilitates the passage of the connecting wire;

[0030] A magnetic ring 10 is arranged on one side of the inductor coil 8. The magnetic ring 10 is of a hollow design. The magnetic ring 10 and the outer periphery of the central limiting tube 6 are designed for limiting sliding. A magnetic ring protection pad 9 is arranged between the magnetic ring 10 and the inductor coil 8. The magnetic ring protection pad 9 and the central limiting tube 6 are designed for slidable movement. The magnetic ring protection pad 9 can play a role in protecting the magnetic ring 10 when it drops rapidly;

[0032] Among them, in order to achieve power supply, a power source is arranged on the fixing plate 1. The power source can be selected from various existing batteries and is controlled by a switch, but this method has relatively low fun;

[0033] In order to further improve the fun of children, the present application adopts a hand-cranked power generation part 3 to generate electricity by hand-cranking. During the cranking process, electricity is generated, a magnetic field is generated in the coil part, and magnetic repulsion is generated with the magnetic ring 10, achieving the function of the magnetic ring 10 to jump;
