It uses electromagnetic force to offset the earth's gravity, allowing the train to float and run on the track.

[0003] The working principle of the double-track maglev train involves the principle of magnetic field. When the magnet moves, it will cut the magnetic lines of force, generate induced current, and then generate a magnetic field. This magnetic field interacts with the magnetic field on the track, allowing the magnet to float on the track. When the magnet moves on the track, the coil on the track will generate current, pushing the magnet forward.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example 1: Please refer to Figure 1 - Figure 3A double-track maglev train principle demonstration device of the present embodiment includes a base 1 and a maglev train structure model 2. Two first copper coils 3 are arranged on one side of the top of the base 1. The two first copper coils 3 are placed side by side on the top of the base 1. Two second copper coils 4 are arranged on the other side of the top of the base 1. The two second copper coils 4 are placed side by side on the top of the base 1. Two maglev train structure models 2 are respectively located on the top of the two first copper coils 3 and the two second copper coils 4. A plurality of fixed blocks 7 are fixedly connected to the top of the base 1. A plurality of movable grooves 9 are processed on both sides of the base 1. The interiors of the plurality of movable grooves 9 are all movably connected. A plurality of limit blocks 8 are connected, a plurality of fixed blocks 7 and limit blocks 8 are symmetrically arranged on both sides of the first copper coil 3, a plurality of fixed blocks 7 and limit blocks 8 are symmetrically arranged on both sides of the second copper coil 4, a plurality of plug blocks 10 are arranged at both ends of the first copper coil 3 and the second copper coil 4, and the maglev train structure model 2 includes a battery 201, a first neodymium magnet 202 and a second neodymium magnet 203, the battery 201 is located between the first neodymium magnet 202 and the second neodymium magnet 203, one end of the battery 201 is magnetically connected to one side of the first neodymium magnet 202, and the other end of the battery 201 is magnetically connected to one side of the second neodymium magnet 203;

[0023] Among them, after the battery 201 is adsorbed and connected with the first neodymium magnet 202 and the second neodymium magnet 203, the maglev train structure model 2 is placed above the two coils, and the battery 201 forms a closed loop through the first neodymium magnet 202, the second neodymium magnet 203 and the first copper coil 3 at both ends, and the current flows from the positive pole to the negative pole, and the coil generates a magnetic field of N backwards and left according to the right-hand screw rule. The first copper coil 3 generates a rightward pulling force on the first neodymium magnet 202 and a rightward thrust on the second neodymium magnet 203 through the magnetic field, so that the maglev train structure model 2 moves to the right;

[0024] Secondly, by setting two groups of fixing blocks 7 and limiting blocks 8, the two groups of fixing blocks 7 and limiting blocks 8 will respectively fix the two first copper coils 3 and the two second copper coils 4 to prevent the first copper coils 3 and the second copper coils 4 from rolling and deviating. The two first copper coils 3 and the two second copper coils 4 are placed side by side, and the two magnetic levitation train structure models 2 will be located above the two first copper coils 3 and the two second copper coils 4 respectively. By setting plug blocks 10 at both ends of the first copper coil 3 and the second copper coil 4, the first copper coil 3 and the second copper coil 4 will be limited by the plug blocks 10 to prevent the first copper coil 3 and the second copper coil 4 from moving;

[0025] Furthermore, by providing a baffle 6, the maglev train structure model 2 can be blocked on the same side of the baffle 6. When the baffle 6 is removed upward, the baffle 6 will be out of contact with the two maglev train structure models 2, so that the two maglev train structure models 2 can start to move at the same time. Since the coil of the first copper coil 3 is wound more densely and the coil of the second copper coil 4 is wound more sparsely, a variable is provided to compare the speeds at which the maglev train structure model 2 moves on the top of the first copper coil 3 and the second copper coil 4 respectively.

[0026] Furthermore, two brackets 5 are fixedly connected to the top of the base 1, and baffles 6 are plug-connected to the tops of the two brackets 5. The baffles 6 are located on one side of the maglev train structure model 2. By plugging both ends of the baffles 6 into the inside of the brackets 5, the baffles 6 can be fixed so that the baffles 6 can block the two maglev train structure models 2 at the same time.

[0027] Further, the top of the limit block 8 is fixedly connected with a connecting block 12, and the inside of the connecting block 12 is movably connected with a limit column 13, and the top of the limit column 13 is fixedly connected with a pulling block 14, and the bottom of the limit column 13 is plug-connected inside the movable groove 9. By pulling the pulling block 14 upward, the pulling block 14 will drive the limit column 13 to move upward, so that the bottom of the limit column 13 is separated from the bottom inner wall of the movable groove 9, so that the connecting block 12 can be moved, and the connecting block 12 will drive the limit block 8 to move, so that the coil of the limit block 8 is separated, which is convenient for disassembly and replacement of the first copper coil 3 or the second copper coil 4;

[0028] Furthermore, a return spring 15 is disposed outside the limit column 13, one end of the return spring 15 is fixedly connected to the top of the connection block 12, and the other end of the return spring 15 is fixedly connected to the bottom of the pull block 14. When the pull block 14 is pulled upward, the pull block 14 will pull one end of the return spring 15 to extend, and when the pull block 14 is released, the return spring 15 will contract and drive the pull block 14 to return to its original position.

[0029] Furthermore, a limiting hole 16 is processed inside the movable groove 9, and the bottom of the limiting column 13 is plug-connected inside the limiting hole 16. By plugging the bottom of the limiting column 13 into the limiting hole 16, the limiting block 8 can be limited.

[0030] Furthermore, the bottom of the limit block 8 is fixedly connected with two sliders 17, and two slide grooves 18 are processed on both sides of the movable groove 9. The sliders 17 are movably connected inside the slide grooves 18. When the limit block 8 moves, the limit block 8 will drive the sliders 17 to move, and the sliders 17 will move along the inside of the slide grooves 18. By providing the slide grooves 18, the movement of the limit block 8 can be limited to prevent the limit block 8 from being separated from the inside of the movable groove 9.

[0031] Furthermore, a plurality of slots 11 are processed on the top of the base 1, and the bottoms of the plurality of plug-in blocks 10 are plug-connected inside the slots 11. Since the plug-in blocks 10 are plugged into the inside of the slots 11, it is convenient to remove the plug-in blocks 10, thereby facilitating the replacement of the first copper coil 3 or the second copper coil 4.

[0032] Working principle: by placing two maglev train structure models 2 above the first copper coil 3 and the second copper coil 4, and then taking out the baffle 6 upwards, the baffle 6 is disconnected from the two maglev train structure models 2. Since the battery 201 forms a closed loop through the first neodymium magnet 202, the second neodymium magnet 203 and the first copper coil 3 at both ends, the current flows from the positive pole to the negative pole, and according to the right-hand screw rule, the coil generates a magnetic field of N to the left. The first copper coil 3 generates a rightward pulling force on the first neodymium magnet 202 and a rightward thrust on the second neodymium magnet 203 through the magnetic field, so that the maglev train structure model 2 moves to the right. The two maglev train structure models 2 will start to move at the same time. Since the coil of the first copper coil 3 is wound more densely and the coil of the second copper coil 4 is wound more sparsely, the speed at which the maglev train structure model 2 moves on the top of the first copper coil 3 and the second copper coil 4 respectively is compared.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
