As shown in fig. 1, fig. 1 is a structural diagram of a mover assembly applied to a magnetic levitation elevator according to an embodiment of the present invention, where the mover assembly includes a mounting base 20, and a magnet assembly 10 mounted on the mounting base 20; the mounting seat 20 comprises a base body 200 and a plurality of rows of magnet assembly mounting structures arranged on the base body, wherein a plurality of groups of magnet assemblies 10 are mounted on each row of magnet mounting structures; wherein, multirow magnet mounting structure parallel arrangement each other, and the mutual one-to-one of the magnet assembly 10 of the last installation of per two rows of magnet mounting structure is provided with coil space 201 between per two rows of magnet assembly 10 for hold the coil. By the design, N-1 rows of coils can be arranged between the N rows of magnet assembly mounting structures, and compared with the design mode that each two independent rows of magnets correspond to one row of coils, the number of the magnets can be greatly reduced.

Specifically, each row of the magnet assembly mounting structures comprises a plurality of magnet assembly mounting positions, and each magnet assembly mounting position is provided with one magnet assembly 10.

The magnet assembly 10 includes a first magnet block 101, a second magnet block 102, and a third magnet block 103; the magnet assembly mounting position comprises a plurality of supporting columns 202 protruding upwards, wherein two supporting columns surround to form a rectangular frame 203 with an opening at one side; the supporting column is provided with a stopping portion 204, the first magnet block 101 and the second magnet block 102 are mounted at the rectangular frame 203, the stopping portion 204 separates the first magnet block 101 from the second magnet block 102, a gap space is formed between the first magnet block 101 and the second magnet block 102, and the third magnet block 103 is placed in the gap space.

Specifically, in some embodiments, the first magnet block 101 and the second magnet block 102 have the same shape, and correspond to the rectangular frame 203 of the magnet assembly mounting position, and the first magnet block and the second magnet block are rectangular plate-shaped. So designed thatThe magnet block is convenient to process and install, and the cost is reduced. In some embodiments, the lengths of the first and second magnet blocks are greater than the height of the support column, so that the first and second magnet blocks can protrude out of the rectangular frame after being mounted at the rectangular frame, thereby facilitating the detachment of the magnet blocks. In practical application, if the length of the magnet block is too long, the protruding part is too much, and the magnet block is not stable easily after being installed on the rectangular frame; if the length of the magnet block is too short, the magnet block is inconvenient to disassemble, so that in the embodiment of the invention, the height of the support column and the lengths of the first magnet block and the second magnet block meet the following requirements:

wherein h is the height of the support column, and l is the length of the first and second magnet blocks. It should be noted that the length of the magnet block and the height of the supporting column may be set in other proportional relationships, and are not particularly limited in the embodiment of the present invention. In some embodiments, after the first and second magnet blocks are mounted in the rectangular frame, the surfaces of the magnet blocks protrude outward, so that the surfaces of the magnet blocks are displaced from the plane of the support post.

The third magnet block 103 is in a sheet shape, in the embodiment of the invention, the third magnet block 103 is in a rectangular sheet shape, the length of the third magnet block is smaller than that of the first magnet block and that of the second magnet block, and the width of the third magnet block is matched with the distance between the stop parts of the two support columns. It is understood that the third magnet block may be configured in other shapes as long as it can be placed in the gap space formed by the first and second magnet blocks.

The stopping part 204 of the supporting column 202 is configured to be arranged along the transverse center line of the supporting column 202, and the stopping part 204 is in a vertical bar shape; in the embodiment of the present invention, the thickness of the stopping portion 204 is equal to the thickness of the third magnet block 103, and the distance between two stopping portions 204 of the same rectangular frame 203 is equal to the width of the third magnet block 103; the thickness of the gap space formed after the first magnet block and the second magnet block are arranged at the positions of the rectangular frame is equal to that of the stopping part, so that the third magnet block can be tightly arranged in the gap space. In some embodiments, the distance between the two support columns of the same rectangular frame is equal to the width of the first magnet block and the width of the second magnet block, so that the first magnet block and the second magnet block can be stably and fixedly mounted at the rectangular frame.

Referring to fig. 3 and 5, in some embodiments, the magnet assembly mounting structure further includes a main body 205, the main body 205 is perpendicular to the base body 200 of the mounting base, the main bodies 205 of the multiple rows of magnet assembly mounting structures extend to the same side perpendicular to the base body, and a groove 206 is formed between the main bodies 205 of each two rows of magnet assembly mounting structures. The supporting posts of the magnet assembly mounting position are disposed on the main body 205 and protrude upward, so that all the supporting posts 202 can be ensured to be on the same line. In addition, by providing the main body 205, after the magnet block is mounted on the magnet assembly mounting position, the magnet block is displaced by a distance S in a direction perpendicular to the plane of the base body 200 of the mounting base, so that the magnet block can be easily removed. Of course, in some embodiments, the magnet assembly mounting structure may have no main body portion, i.e., the support posts of the magnet assembly mounting structure directly protrude out of the plane of the base body, so that the magnet block is closely contacted with the plane of the base body after the magnet block is mounted on the magnet assembly mounting position, which is very inconvenient for the magnet block to be dismounted and mounted.

Referring to fig. 4, in some embodiments, for the middle magnet assembly 10, since the magnet attraction forces F of the magnet blocks on the left and right sides are equal, the forces on the left and right sides of the middle magnet assembly 10 are substantially balanced, and the supporting force of the magnet assembly mounting structure is small, the magnet assembly mounting structure in the middle row can be made thinner, for example: the thickness of the main body part and the support columns of the middle row of magnet assembly mounting structures can be set to be smaller than that of the two rows of edge magnet assembly mounting structures, and therefore material cost is saved conveniently.

In some embodiments, the stopping portions 204 are symmetrically disposed on both sides of the supporting column 202, and the stopping portions 204 of the supporting columns 202 are located on the same plane.

In the novel embodiment, the magnet mounting seat is made of stainless steel. It is understood that in other embodiments, the magnet mounting base may be made of other high-strength non-metallic materials.

In the embodiment of the invention, the first magnet block and the second magnet block are arranged at the rectangular frame and are separated by the stopping part, a gap space is formed between the first magnet block and the second magnet block, the third magnet block is arranged in the gap space, and the first magnet block and the second magnet block are tightly adsorbed together by magnetic force to form a complete magnet assembly. And through setting up the integrative integrated configuration of multirow magnet subassembly mounting structure, can set up N-1 row coil between the N row magnet subassembly mounting structure, for one row coil structure is corresponded to two rows of magnet subassemblies alone, the magnet quantity has significantly reduced. Secondly, except two rows of magnet subassembly mounting structure in edge, the structure of middle row magnet subassembly mounting structure can design very thinly to practice thrift design cost and material cost.
