Description

Technical Field

[0001] This utility model relates to a demonstration device, specifically a magnetic levitation teaching demonstration device. Background Technology

[0002] Magnetic levitation is a technology that uses magnetic force to overcome gravity and levitate objects. There are many ways to achieve magnetic levitation technology, which can be mainly divided into passive levitation where the system is self-stabilized and active levitation where the system is not self-stabilized.

[0003] Currently, the teaching of magnetic levitation technology usually involves attaching a ring magnet to a magnetic levitation pen and placing it on top of a base magnet to conduct a magnetic levitation experiment. This experiment is rather boring and fails to attract students' attention, resulting in poor teaching effectiveness. Utility Model Content

[0004] The purpose of this invention is to overcome at least one of the defects of the existing technology and provide a magnetic levitation teaching demonstration device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A magnetic levitation teaching demonstration device includes:

[0007] The track has a pair of first magnetic strips spaced apart on its bottom surface;

[0008] A levitation demonstration piece, wherein a pair of second magnetic strips are provided on one side of the levitation demonstration piece near the bottom surface of the track, and the second magnetic strips repel the first magnetic strips;

[0009] A drive component located on the upper surface of the floating demo unit is used to provide power to the floating demo unit.

[0010] Furthermore, the track is at least one or a combination of a straight track, a circular straight track, and an S-shaped straight track.

[0011] Furthermore, the four corners of the suspended demonstrator are provided with guide wheels, which contact the inner wall of the track to reduce the friction between the suspended demonstrator and the track.

[0012] Furthermore, the drive assembly includes a motor, a battery, and a propeller, with the motor connected to the battery and the propeller connected to the output shaft of the motor.

[0013] Preferably, the motor is a high-speed DC motor.

[0014] Preferably, the battery is a lithium battery.

[0015] Furthermore, there are multiple floating demonstration components, which are connected into one unit by first and second connectors located at the beginning and end of the floating demonstration components.

[0016] Furthermore, the pair of first magnetic strips and the pair of second magnetic strips are arranged in a position opposite to each other.

[0017] Furthermore, the track is a modular, spliced ​​track.

[0018] Preferably, the modular track is composed of multiple straight track modules and / or multiple curved track modules spliced ​​together.

[0019] Compared with existing technologies, this utility model provides a magnetic levitation teaching demonstration device. This device uses a magnetic levitation vehicle as a carrier and utilizes the principle of mutual repulsion between the first and second magnetic strips of the same polarity to suspend the demonstration component in the air. A drive assembly then propels the suspended demonstration component to run on a track, thereby attracting students' interest and improving teaching effectiveness. Furthermore, this device features a modular assembly structure. During teaching, students can use different modules to build more complex and larger magnetic levitation systems, simulating real train track systems, further enhancing student interest and facilitating teaching.

[0029] In this embodiment, the track 1 is at least one or a combination of a straight track, a circular straight track, and an S-shaped straight track.

[0030] In this embodiment, guide wheels 8 are provided at the four corners of the suspended demonstration component 2. The guide wheels 8 are in contact with the inner wall of the track 1 to reduce the friction between the suspended demonstration component 2 and the track 1.
