[0043] The first magnetic member 210 and the second magnetic member 310 may be electromagnets or permanent magnets with the same poles facing each other to generate a repulsive force that enables the train body 300 to suspend above the magnetic suspension track 100. The moving member 220 may be in the form of a plate, block or belt, etc., which is not limited here.

[0044] In this embodiment, the magnetic levitation track 100 can be laid on the base 110. The base 110 can be arranged in a rectangular parallelepiped shape, and an installation space for laying the magnetic levitation track 100 can be arranged thereon.

[0047] Please refer to Figure 2 In some embodiments, the driving mechanism 400 may include a motor 410 and a transmission member 420, wherein the transmission member 420 is connected to the driving end of the motor 410 and is provided with a mounting portion for mounting the moving member 220; the transmission member 420 is used to drive the moving member 220 to perform linear motion along the length direction of the base 110 under the drive of the motor 410. In this way, the function of converting the rotary motion output by the motor 410 into linear motion is realized, thereby driving the train body 300 to perform linear motion along the length direction of the magnetic suspension track 100.

[0048] It should be noted that in actual application scenarios, the shape of the magnetic levitation track 100 can be set to achieve linear, curved, circular or a combination of movement of the train body 300, and it is not limited to linear movement.

[0049] It should also be noted that in this embodiment, the transmission member 420 can be a screw rod, a gear set, a transmission belt or a chain, etc., which is not limited here.

[0050] When the transmission member 420 is a screw rod, the magnetic suspension track 100 may be provided with two slide rails, and the positions of the moving member 220 corresponding to the two slide rails may be provided with slide grooves adapted for sliding connection, and the position of the moving member 220 corresponding to the screw rod may be provided with a connection hole for the screw rod to pass through. In this way, the linear transmission of the screw rod is realized, so that the moving member 220 can slide along the magnetic suspension track 100.

[0051] In order to control the running speed of the train body 300 , the maglev train may further include a control panel (not shown), which is disposed on the base 110 and electrically connected to the motor 410 to control the rotation speed and running direction of the motor 410 .

[0052] Furthermore, the maglev train may also include two position sensors (not shown), which are disposed at both ends of the maglev track 100 to detect position signals of the moving part 220 or the train body 300 .

[0053] In this embodiment, the control board can also be used to control the motor 410 to reverse according to the position signal, so as to drive the transmission member 420 to drive the moving member 220 to perform linear reciprocating motion along the length direction of the base 110, so as to drive the train body 300 to perform linear reciprocating motion above the base 110.

[0054] The control board can use microprocessors such as single chip microcomputer, DSP and FPGA, but there is no limitation here.

[0055] Among them, DSP (Digital Signal Processing) chip refers to a chip that can implement digital signal processing technology. The DSP chip adopts a Harvard structure that separates program and data, has a dedicated hardware multiplier, and provides special DSP instructions that can be used to quickly implement various digital signal processing algorithms.

[0056] FPGA (Field Programmable Gate Array) devices are a kind of semi-customized circuit in application-specific integrated circuits. They are programmable logic arrays that can effectively solve the problem of the small number of gate circuits in the original devices. The basic structure of FPGA includes programmable input and output units, configurable logic blocks, digital clock management modules, embedded block RAM, wiring resources, embedded dedicated hard cores, and bottom-level embedded functional units. Due to the characteristics of rich wiring resources, reprogrammable and high integration, and low investment, FPGA has been widely used in the field of digital circuit design. The design process of FPGA includes algorithm design, code simulation, design, and board debugging. Designers and actual needs establish algorithm architecture, use EDA to establish design solutions or HD to write design codes, and ensure that the design solutions meet actual requirements through code simulation. Finally, board-level debugging is performed, and the relevant files are downloaded to the FPGA chip using the configuration circuit to verify the actual operation effect.

[0057] The position sensor may include a first stop switch and a second stop switch. The maglev track 100 has a first end and a second end opposite to each other in the length direction. The first stop switch may be installed at the first end of the maglev track 100 , and the second stop switch may be installed at the second end of the maglev track 100 .

[0058] When the train body 300 is at the first end of the magnetic levitation track 100, the first stop switch is triggered, and the control board controls the motor 410 to reverse, drive the moving part 220 and the first magnetic part 210 thereon to make linear motion in the opposite direction, and then drive the train body 300 to make a reverse linear motion; when the train body 300 is at the second end of the magnetic levitation track 100, the second stop switch is triggered, and the control board controls the motor 410 to reverse, drive the moving part 220 and the first magnetic part 210 thereon to make a linear motion in the opposite direction, and then drive the train body 300 to make a reverse linear motion. In this way, the train body 300 is able to make a linear reciprocating motion above the base 110.

[0059] Of course, in some other embodiments, proximity sensors can also be used to detect position signals. A proximity sensor refers to a switch that can send an "action" signal when an object approaches it to a set distance, and it does not need to be in direct contact with the object. There are many types of proximity switches, mainly electromagnetic, photoelectric, differential transformer, eddy current, capacitor, reed switch, Hall, etc.

[0060] In this embodiment, the control board can be connected to the power module, which can be a power circuit that accepts external power input for power conversion processing, or a power circuit that includes a battery and manages the output of the battery power, or a power circuit that has both and can be switched for use.

[0061] In order to achieve smooth train operation, refer to Figure 1 and Figure 2 The train body 300 includes a plurality of carriages connected in sequence, and a float with a second magnetic member 310 is provided at the bottom of each carriage. The plurality of carriages are arranged in a one-to-one correspondence with the plurality of moving members 220, so that the plurality of second magnetic members 310 are arranged in a one-to-one correspondence with the plurality of first magnetic members 210. In this way, the running stability of the train body 300 can be further improved.

[0062] In this embodiment, a plurality of floats with the second magnetic member 310 may be evenly spaced and arranged at the bottom of the train body 300 , and are arranged opposite to the moving member 220 with the first magnetic member 210 .

[0063] In one embodiment, reference Figure 2The maglev train may further include a cover plate 120, which is disposed on the moving part 220 to shield the moving part 220, the first magnetic part 210 and other components on the base, thereby making the base as a whole more concise and beautiful.

[0064] In order to protect the train body 300 to avoid accidents caused by people accidentally touching the train during the train demonstration operation and improve the safety of the maglev train, in one embodiment, reference is made to Figure 2 The maglev train further includes a transparent cover 130 , which is disposed on the base 110 to cover the maglev track 100 and the train body 300 .

[0065] In this embodiment, the transparent cover 130 may be made of materials such as PC, PMMA, glass, etc., which are not limited here.

[0066] In addition, in some embodiments, reference Figure 2 The maglev train may further include a support frame 140 , which is disposed at the bottom of the base 110 to support the base 110 .

[0067] It should be noted that the bottom end of the support frame 140 may be provided with an anti-skid pad or a universal wheel with a self-locking function, etc., which is not limited here.

[0068] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
