Magnetic levitation device

A magnetic levitation device comprising:

• an inner component;
• a first magnet ring securely mounted on the inner component;
• two groups of second magnet rings securely mounted on the inner component, the first magnet ring located between the two groups of the second magnet rings;
• each group of the second magnet rings comprising:
• a closer second magnet ring securely mounted on the inner component;
• a remoter second magnet ring securely mounted on the inner component, a distance between the remoter second magnet ring and the first magnet ring being larger than a distance between the closer second magnet ring and the first magnet ring;
• and
• an interval formed between the closer second magnet ring and the remoter second magnet ring;
• a third magnet ring securely mounted on the inner component, and located above the first magnet ring and between the first magnet ring and the group of the second magnet rings that is located above the first magnet ring;
• an outer component sleeved on the inner component and a space formed between the outer component and the inner component, the inner component and the outer component capable of being rotated with respect to each other;
• a center magnet ring securely mounted on the outer component, the center magnet ring attracted by the first magnet ring;
• and
• two active magnet rings moveably mounted on the outer component and respectively located in the intervals of the two groups of the second magnet rings, each one of the active magnet rings attracted by the closer second magnet ring and the remoter second magnet ring of the corresponding group of the second magnet rings;
• a reactive magnet ring moveably mounted on the outer component and above the center magnet ring, a distance between the reactive magnet ring and the center magnet ring smaller than a distance between the first magnet ring and the third magnet ring that is above the first magnet ring, the reactive magnet ring attracted by the third magnet ring;
• a loading component configured to load external force, the loading component mounted on the outer component and under the center magnet ring;
• a plurality of pulley assemblies mounted on the outer component, each one of the pulley assemblies comprising:
• a center pulley securely mounted on the outer component and aligned to the center magnet ring;
• two fixing points connected with a respective one of the active magnet rings and thereby each one of the fixing points being capable of being synchronously moved with the connected active magnet ring;
• two reactive pulleys respectively connected with the reactive magnet ring and the loading component, and thereby each one of the reactive pulleys being capable of being synchronously moved with the connected reactive magnet ring or the connected loading component;
• and
• an elastic component connected with the center pulley;
• and
• two ropes wrapped on the center pulley, one end of each one of the ropes mounted on one of the fixing points, and another end of said rope mounted on one of the reactive pulleys.
