[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The core of the utility model is to provide a suspension electromagnet, and the upper surface of the magnetic pole is set as a preset curved surface, so as to prevent the suspension electromagnet from touching the track.

[0031] Another core of the utility model is to provide a high-speed maglev train including the above-mentioned suspension electromagnet.

[0032] Please refer to Figures 1 to 4 .

[0033] This specific embodiment discloses a levitation electromagnet, comprising: a magnet back box 1 and a plurality of magnetic poles 2; the plurality of magnetic poles 2 are fixedly arranged in the magnet back box 1, and the upper surfaces of all the magnetic poles 2 are preset curved surfaces 5; the preset curved surface 5 is mirror-set to the deformation curved surface; the deformation curved surface is a surface formed by the bending deformation of the upper surface of the magnetic pole 2 located on the reference plane in a fully loaded state; the reference plane is a horizontal plane intersecting with the top endpoint of the preset curved surface 5.

[0034] It should be noted that the reference plane mentioned in this specific embodiment is a horizontal plane. The existing magnetic pole 2 is generally arranged according to the reference plane, that is, the upper surface of the magnetic pole 2 is located at the horizontal plane where the reference plane is located. However, in a fully loaded state, the magnetic pole 2 will deform upward and easily contact the track, affecting the normal operation of the vehicle.

[0035] In the process of using the suspension electromagnet provided by this specific embodiment, since the upper surface of all the magnetic poles 2 is the preset curved surface 5; the preset curved surface 5 and the deformation curved surface are mirrored; the deformation curved surface is the surface formed by the bending deformation of the upper surface of the magnetic pole 2 located on the reference plane in the full-load state; the reference plane is the horizontal plane intersecting with the top end point of the preset curved surface 5. This is equivalent to setting the suspension electromagnet in the opposite direction of the deformation in advance to avoid the suspension electromagnet from touching the track due to deformation, so that when fully loaded or loaded, the suspension electromagnet deforms to make the preset curved surface 5 closer to the plane, which can effectively avoid the preset curved surface 5 from touching the track.

[0036] On the basis of the above embodiment, along the distribution direction of the magnetic pole 2, the preset curved surface 5 can include a first end 51, an intermediate inflection point 52 and a second end 53, a first curved surface concave downward is formed between the first end 51 and the intermediate inflection point 52, and a second curved surface gradually extending downward from the intermediate inflection point 52 to the second end 53 is formed between the intermediate inflection point 52 and the second end 53.

[0037] like Figure 4 As shown, in the cross section of the preset curved surface 5, it includes a first end 51, a second end 53 and an intermediate inflection point 52, and the intermediate inflection point 52 is located between the first end 51 and the second end 53, a downwardly concave and smooth first curved surface is formed between the first end 51 and the intermediate inflection point 52, and a gradually downwardly extending and smooth second curved surface from the intermediate inflection point 52 to the second end 53 is formed between the intermediate inflection point 52 and the second end 53.

[0038] Specifically, the first end 51 and the middle inflection point 52 may be made to have the same height.

[0039] It should be noted that, depending on the actual situation, the height of the first end 51, the second end 53 and the middle inflection point 52 in this specific embodiment needs to be determined based on the deformation of the magnetic pole 2 set on the reference plane under the full load state. When the number, setting position and size of the magnetic pole 2 change, the height of the first end 51, the second end 53 and the middle inflection point 52 will change, the degree of concavity of the first curved surface will also change, and the curvature of the first curved surface and the second curved surface will also change. The specific height is determined according to the actual situation and will not be elaborated here.

[0040] In a specific embodiment, the magnet back box 1 includes a back box body and end plates 3 arranged at both ends of the back box body in the length direction, and a plurality of magnetic poles 2 are distributed along the length direction of the back box body.

[0041] In the specific setting process, Figure 1 As shown, the magnetic pole 2 is arranged along the length direction of the back box body, and the two end plates 3 are located on the outside of the magnetic pole 2 and at both ends of the length direction of the back box body, which can better protect the magnetic pole 2.

[0042] On the other hand, the suspension electromagnet may further include a support arm mounting seat 4, which is connected to the magnet back box 1 and is used to fix the magnet back box 1 to the support arm. The support arm mounting seat 4 includes a mounting seat body and a crossbeam for supporting the magnetic pole 2.

[0043] The function of the bracket mounting seat 4 is to enhance the overall rigidity of the suspension electromagnet so that the vertical rigidity of the new suspension electromagnet is basically consistent with that of the standard suspension electromagnet.

[0044] Furthermore, while the strength of the support arm mounting base 4 is met, a plurality of weight-reducing holes can be provided on the support arm mounting base 4 to facilitate lightweighting.

[0045] Reinforcing ribs for increasing strength may also be provided on the bracket arm mounting seat 4 .

[0046] In addition to the above-mentioned levitation electromagnet, the utility model also provides a high-speed maglev train including the levitation electromagnet disclosed in the above-mentioned embodiment. The high-speed maglev train includes the levitation electromagnet mentioned in any of the above items and a car body, and the length of the levitation electromagnet is greater than the length of the car body. For the structures of other parts of the high-speed maglev train, please refer to the prior art and will not be repeated in this article.

[0047] Furthermore, the length of the suspension electromagnet can be made half of the total length of the two carriage bodies in a connected state, and the total length of the two carriage bodies is the sum of the length of the two carriage bodies and the length of the gap between two adjacent carriage bodies.

[0048] On the other hand, two adjacent suspension electromagnets can be arranged independently of each other.

[0049] The length of the existing suspension electromagnet is generally consistent with the length of the carriage body. Two adjacent carriage bodies need to correspond to three suspension electromagnets, two of which correspond to the two carriage bodies respectively, and the other suspension electromagnet is used to connect the two adjacent carriage bodies. During the marshaling process, the suspension electromagnets need to be repeatedly disassembled and installed.

[0050] In this specific embodiment, during specific use, when the vehicle needs to be re-organized, since the length of the suspension electromagnet is half of the total length of the two car bodies in a connected state, and the two adjacent suspension electromagnets are independently arranged, there is no need to set a disassembly electromagnet between the two adjacent car bodies. The functions of three existing standard electromagnets can be achieved by two overlapping suspension electromagnets, thereby reducing the number of suspension electromagnets arranged between vehicles and reducing the disassembly and assembly of electromagnets during the vehicle organization process.

[0051] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other. Any combination of all embodiments provided by the utility model is within the protection scope of this utility model and will not be described in detail here.

[0052] The above is a detailed introduction to the levitation electromagnet and high-speed maglev train provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
