Description

Technical Field

[0001] The utility model relates to the field of magnetic suspension devices, in particular to a spliced ​​magnetic suspension device. Background Art

[0002] Levitation technology, also known as magnetic levitation, utilizes magnetic fields to suspend objects in mid-air. Magnetic levitation technology is widely used in transportation, industrial production, healthcare, and scientific research. Maglev trains, for example, are the most famous application of magnetic levitation technology, enabling high-speed travel and reduced friction. Magnetic levitation technology can also be used in material handling and processing processes requiring frictionless motion. As magnetic levitation technology matures, a growing number of devices are appearing in the civilian market, including educational supplies, crafts, souvenirs, models, toys, ornaments, and trendy accessories.

[0003] Magnetic levitation principle: Magnetic levitation devices have two types of levitation: downward levitation and upward levitation. In upward levitation, when the circuit is energized, the electromagnet generates a magnetic field, creating an attractive force between the electromagnet and the permanent magnet. The magnetic levitation control system adjusts the current to change the strength of the magnetic field, thereby varying the strength of the attraction between the electromagnet and the permanent magnet. When the attractive force is balanced with the weight of the object, the object remains suspended in a stable state.

[0004] The magnetic levitation device includes a frame and a suspension, and a display area is set on the frame. The suspension and the frame can generate magnetic fields. The frame generates a repulsive force or an attractive force on the suspension, so that the suspension floats in the display area. The structure and shape of the frame and the suspension in the existing magnetic levitation device are fixed. The shape of the suspension is single. Displaying the suspension requires replacing the entire suspension. Moreover, if the volume of the suspension is large, the display space of the fixed-shaped frame is fixed, and the suspension cannot be effectively displayed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technical solutions, the utility model provides a spliced ​​magnetic suspension device, which can effectively solve the technical problem of the single shape of the frame and the suspension body.

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

[0007] A splicing-type magnetic levitation device includes a base body and a suspension body. A suspension area is arranged around the base body. Both the base body and the suspension body can generate magnetic fields. The magnetic field of the base body corresponds to the magnetic field of the suspension body. The base body is used to generate a force on the suspension body so that the suspension body is suspended in the suspension area. The base body is composed of more than two base blocks, and any two base blocks can be detachably spliced. An electromagnet is arranged in at least one base block, and the electromagnet can generate a magnetic field when energized. The suspension body is composed of more than two suspension blocks, and any two suspension blocks can be detachably spliced. A permanent magnet is arranged in at least one suspension block, and the magnetic field axis of the permanent magnet and the magnetic field axis of the electromagnet are located on the same axis.

[0008] Furthermore, the base blocks and the suspension blocks are both provided with docking holes and docking posts, and two adjacent base blocks or suspension blocks can be spliced ​​together by inserting the docking posts into the docking holes.

[0009] Furthermore, the side wall of the docking column is provided with two or more positioning parts, an extrusion groove is provided between the two positioning parts, and the inner wall of the docking hole is provided with a positioning groove corresponding to the positioning part. When the docking column is inserted into the docking hole, the positioning part engages with the positioning groove.

[0010] Furthermore, the base blocks and the suspension blocks are both provided with magnetic blocks, and the polarities of the opposite ends of the magnetic blocks on the side where the two base blocks or the two suspension blocks are spliced ​​together are opposite, so that the two base blocks or the two suspension blocks can be adsorbed on each other.

[0011] Furthermore, a main control circuit board is provided in any one of the two or more base blocks, and the main control circuit board is electrically connected to the electromagnet. The main control circuit board is used to control the size and direction of the magnetic field generated when the electromagnet is energized.

[0012] Furthermore, the main control circuit board is also electrically connected to a power supply port, a power supply and a main control switch, which all extend to the surface of the base block. The main control switch can be an induction switch, a remote control switch or a button switch.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the base body is composed of more than two base blocks, and two adjacent base blocks are detachably connected. The suspension body is composed of more than two suspension blocks. An electromagnet is provided in any base block, and a permanent magnet is provided in any suspension block.
