Description

Technical Field

[0001] The utility model relates to the field of suspension devices, in particular to an upper suspension rotating display device. Background Art

[0002] Magnetic levitation is a technology that uses magnetic fields to suspend objects in the air. It is also called magnetic levitation technology. Magnetic levitation technology is mostly used in transportation, industrial production, medical treatment, scientific research, etc. For example, the maglev train is the most famous application of magnetic levitation technology, which can achieve high-speed travel and reduce friction. Magnetic levitation technology can be used for material handling and processing that requires frictionless motion. With the maturity of magnetic levitation technology, more and more magnetic levitation devices have appeared in the civilian market, such as magnetic levitation teaching supplies, crafts, souvenirs, models, toys, ornaments, trendy toys and other products.

[0003] Principle of magnetic levitation: There are two types of levitation in magnetic levitation devices, one is downward levitation and the other is upward levitation. In downward levitation, when the circuit is powered on, the electromagnet generates a magnetic field, which generates a repulsive force with the permanent magnet. The magnetic levitation control system changes the magnetic field by adjusting the current, thereby changing the repulsive force with the permanent magnet. When the repulsive force is balanced with the gravity of the suspended object, the suspended object can be suspended in the air in a stable state.

[0004] An existing magnetic suspension ornament includes a base, a frame, and a suspension body suspended by magnetic field force in the middle of the frame. The frame is provided with a driving rotation device corresponding to the bottom of the suspension body. An LED light bar is provided in the frame. At least one surface on the line from the top to the bottom of the frame is a light-transmitting material. The LED light bar is provided with a touch sensor and a sound control sensor. A PCB board electrically connected to the LED light bar is provided in the base. The base is also provided with a clock device, a temperature measuring device and a display screen electrically connected to the PCB board. The display screen is provided on the side or top surface of the base. The electromagnet is driven to rotate by the driving rotation device, so that the suspension body is rotated. The rotation effect is poor, the rotation is not stable, and the rotation speed cannot be controlled. Utility Model Content
