Description

Technical Field

[0001] The utility model relates to the field of suspension devices, in particular to a suspension device that tilts and rotates. Background Art

[0002] A suspension device is a technology that uses magnetic fields to suspend objects in the air, also known as magnetic levitation technology. Most applications of magnetic levitation technology are 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 driving and reduce friction. Magnetic levitation technology can be used in material processing and manufacturing processes that require frictionless movement. With the maturity of magnetic levitation technology, more and more magnetic levitation devices have emerged in the civilian market, such as magnetic levitation teaching aids, handicrafts, souvenirs, models, toys, ornaments, trendy toys, etc.

[0003] Magnetic levitation principle: There are two suspension forms for magnetic levitation devices, one is downward suspension and the other is upward suspension. In downward suspension, when the circuit is powered on, the electromagnet generates a magnetic field, creating a repulsive force with the permanent magnet. The magnetic levitation control system adjusts the magnitude of the current to change the magnitude of the magnetic field, thereby changing the magnitude of the repulsive force with the permanent magnet. When the magnitude of the repulsive force reaches equilibrium with the weight of the suspended object, the suspended object can be suspended in the air in a stable state.

[0004] In existing suspension devices, during the display process, the suspended body can usually only rotate horizontally, and can only display its front or main surface, making it difficult to fully display the details of its top and bottom. Although this display method is simple and clear, it will appear monotonous, lacking a sense of hierarchy and three-dimensionality. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art solutions, the utility model provides a suspension device that tilts and rotates, which can effectively solve the technical problem that the suspended body can only rotate horizontally.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The tilting and rotating suspension device includes a base and a suspension body. An electric control cavity is arranged inside the base, and an electromagnet and a main control circuit board are arranged inside the electric control cavity.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: A fixed housing is provided inside the suspension body, and a driving motor is provided inside the fixed housing. When the suspension body floats in the display area, the axis of the permanent magnet is vertical in the display area.

After the main control switch is turned on, the electromagnet 4 is energized to generate a magnetic field. The end of the electromagnet 4 opposite to the permanent magnet 6 has opposite polarities, namely the "N" pole and the "S" pole. After the electromagnet 4 is energized, it attracts the permanent magnet 6. When the attraction force of the electromagnet 4 on the permanent magnet 6 is equal to the gravity of the entire suspension body 2, the suspension body 2 can be suspended in the display area 7.

[0027] A rotation chamber 8 is provided inside the suspension body 2. A fixed housing 9 is provided inside the rotation chamber 8. The permanent magnet 6 is provided at one end of the fixed housing 9 close to the electromagnet 4. A driving motor 10 is provided inside the fixed housing 9. The axis of the driving motor 10 is inclined and forms an angle with the axis of the permanent magnet 6. The output shaft of the driving motor 10 extends outside the fixed housing 9 and is connected to the inner wall of the suspension body 2. A rotary bearing 11 is provided at one end of the fixed housing 9 away from the driving motor 10. The axis of the rotary bearing 11 coincides with the axis of the driving motor 10. The end of the rotary bearing 11 away from the fixed housing 9 is connected to the inner wall of the suspension body 2. The suspension body 2 is composed of an upper shell 201 and a lower shell 202. Both the upper shell 201 and the lower shell 202 are hemispherical. The edges of the upper shell 201 and the lower shell 202 are connected by a middle fixing ring 203. The upper shell 201 and the lower shell 202 are combined to form a spherical suspension body 2.

[0028] In the tilt-rotating suspension device of this embodiment, a fixed housing 9 is provided inside the suspension body 2, and a driving motor 10 is provided inside the fixed housing 9. When the suspension body 2 is suspended in the display area 7, the axis of the permanent magnet 6 is vertical in the display area 7. The driving motor 10 can drive the suspension body 2 to rotate uniformly relative to the fixed housing 9. Since the axis of the driving motor 10 is inclined and forms an angle with the axis of the permanent magnet 6, the rotation axis of the suspension body 2 is inclined. The suspension body 2 can rotate and display uniformly at a preset tilt angle in the display area 7. Tilt-rotating can display more details and increase the sense of three-dimensionality and spatiality.

[0029] A storage battery 12, a charging circuit board 13, and a charging interface 14 are further disposed in the fixed housing 9. The storage battery 12, the charging interface, and the drive motor 10 are all electrically connected to the charging interface 14. The charging interface 14 extends to the surface of the suspension body 2. An annular bearing seat 204 is provided on the inner wall of the suspension body 2. One end of the rotary bearing 11 is disposed in the bearing seat 204. Both ends of the fixed housing 9 are connected to the suspension body 2 through the output shaft of the drive motor 10 and the rotary bearing 11. When rotating and displaying, the suspension body 2 rotates relative to the fixed housing 9 at a certain angle with the output shaft of the drive motor 10 and the rotary bearing 11 as the fulcrum and the axis. An interface slot 205 is provided in the middle of the bearing seat 204. The charging interface 14 passes through the interface slot 205 and extends to the surface of the suspension body 2. A rotary gap is provided between the side wall of the charging interface 14 and the side wall of the interface slot 205. When rotating and displaying, the suspension body 2 rotates while the position of the charging interface 14 remains unchanged. The charging interface 14 is a DC power socket, and the axis of the charging interface 14 coincides with the axes of the rotary bearing 11 and the drive motor 10. An external power source can be connected through the DC power socket to charge the storage battery 12, and the storage battery 12 supplies power to the drive motor 10.

[0030] A rotary switch is further disposed in the fixed housing 9. The rotary switch is electrically connected to the charging circuit board 13 and the storage battery 12. The rotary switch can be an inductive switch. After the rotary switch is closed, the storage battery 12 is conducted to the drive motor 10, so that the drive motor 10 drives the suspension body 2 to rotate at a constant speed.

[0031] Embodiment 2:

[0032] As Figure 6 shown, the difference between this embodiment and Embodiment 1 is that a solar panel 15 is provided on the surface of the suspension body 2. The solar panel 15 is electrically connected to the charging circuit board 13. The charging circuit board 13 can integrate the output voltage of the solar panel 15 and convert it into a suitable voltage to supply the storage battery 12. Solar energy is a clean and renewable energy source, which saves energy costs and improves reliability. It can be charged without using wires. As long as the surrounding environment is bright enough, the solar panel 15 can convert light energy into electrical energy to charge the storage battery 12.

The wireless power receiving coil 17 and the wireless power supply coil 16 are aligned. The wireless power receiving coil 17 is electrically connected to the charging circuit board 13, and the wireless power supply coil 16 is electrically connected to the main control circuit board 5.
