[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0037] Reference Figure 1 and Figure 2 , Figure 1 The schematic diagram of the structure of the skeleton in the prior art is shown. Figure 2 FIG. 1 shows a schematic diagram of the assembly structure of the frame and the control panel in the prior art. Figure 1 and Figure 2 The skeleton includes a skeleton body 1, the skeleton body 1 includes a first end face 10, and a plurality of buckles 11 are arranged on the first end face 10, and the plurality of buckles 11 are arranged along the circumferential direction of the first end face 10. Correspondingly, a plurality of slots 21 are arranged on the control board 200, and the plurality of slots 21 are arranged along the circumferential direction of the control board 200. The plurality of buckles 11 and the plurality of slots 21 are arranged in a one-to-one correspondence. When the skeleton body 1 and the control board 200 are assembled, the plurality of buckles 11 are respectively engaged in the corresponding slots 21.

[0038] However, in actual assembly, the frame is first assembled with the stator core, and then the wire is wound on the assembly structure of the frame and the stator core. Due to the large winding tension, the buckle 11 is deformed, making it difficult for the buckle 11 to fit with the slot 21. Specifically, Figure 1 The skeleton body 1 also includes a plurality of inserts 12, which are inserted into the cavity of the stator core. A plurality of flanges 13 and open slots 14 are also provided on the first end face 10. The plurality of flanges 13 and the open slots 14 have different heights on the first end face 10. When winding the assembly structure of the stator core and the skeleton, the winding is easy to get caught, and the winding needle is easy to damage the buckle. Moreover, after winding, due to the large tension of the winding, the buckle 11 is very easy to be deformed due to the tension of the winding, making the assembly of the skeleton and the control board 200 very difficult. Even if the buckle 11 is successfully assembled, it is very easy to loosen during use, resulting in abnormal motor performance.

[0039] In addition, in the prior art, the frame and the control board can also be fixed by screwing, but this fixing method will generate a large stress on the control board, causing damage to components on the control board and causing motor abnormality.

[0040] In view of the difficulty in assembling the frame and the control panel in the prior art, the embodiment of the present invention aims to provide a more convenient and reliable frame assembly structure, such as Figures 5 to 7, including a skeleton body 1 and a control board assembly 2, the skeleton body 1 is annular, the skeleton body 1 includes a first end face 10, the control board assembly 2 includes a second end face 20, the first end face 10 corresponds to the second end face 20, a plurality of first connection parts 15 are circumferentially arranged on the first end face 10, and a plurality of second connection parts 22 are arranged on the second end face 20, wherein the plurality of first connection parts 15 correspond to the plurality of second connection parts 22 one by one, the first connection parts 15 and the second connection parts 22 are made of magnetic materials, and the first connection parts 15 and the second connection parts 22 are magnetically attracted and fastened to each other during installation to realize the assembly of the skeleton and the control board. The skeleton assembly structure of the embodiment of the present invention realizes the assembly of the skeleton and the control board by magnetic attraction, and the first connection part 15 does not need to adopt an elastic part like the buckle structure, and its ability to resist deformation is greatly increased, which significantly reduces the assembly difficulty of the skeleton and the control board, ensures the reliability of the assembly structure, and eliminates the stress and strain problem generated when assembling the control board compared to the screwing method, thereby avoiding damage to the electronic components on the control board.

[0041] A boss 16 is provided on the first end surface 10 , and a first opening 17 is provided on the boss 16 . The first opening 17 passes through the top surface of the boss 16 . The first connecting portion 15 is provided at the bottom of the first opening 17 , and the hole depth of the first opening 17 is greater than the height of the first connecting portion 15 . The second connection portion 22 is embedded in the first opening 17 during assembly and is magnetically attracted to the first connection portion 15. In this embodiment, the setting of the boss 16 is used on the one hand to set the first connection portion 15 in the first opening 17, and utilize the portion of the first opening 17 that exceeds the first connection portion 15 to dock with the second connection portion 22. On the other hand, the boss 16 is also used to ensure the distance between the first end face 10 and the second end face 20. After the skeleton and the stator core are assembled, when the skeleton and the stator core are wound, the winding needs to occupy a certain space between the first end face 10 and the second end face 20. Therefore, in this embodiment, if the height of the first connection portion 15 and the second connection portion 22 is not enough to support the winding space, the thickness of the bottom of the boss 16 can be adaptively adjusted.

[0042] Further exemplary description, such as Figure 5 , between adjacent bosses 16, the first end face 10 is a flat plane. In this embodiment, the first end face 10 is a whole circular structure, the structure of the opening groove 14 and the flange structure on the first end face 10 are cancelled, the mold is simpler, the maintenance cost is greatly reduced, the winding is more convenient, the structure is more solid, and the existing skeleton creepage distance and electrical safety problems are solved.

The second connection part 22 is partially embedded in the second opening 23 and partially exposed outside the second end face 20, so as to be embedded in the first opening 17 when assembled with the frame and magnetically attracted to the first connection part 15. In this embodiment, the second connection part 22 can also be selected as a plastic magnet or a magnet. When the second connection part 22 is selected as a plastic magnet, the plastic magnet can be selected to be formed by injection molding a magnetic material in the second opening 23. A temporary template can be pre-set on the second end face 20, connected to the second opening 23 to form an injection molding groove, and the template is removed after the plastic magnet is injection molded. Alternatively, the plastic magnet can be selected to be set in the second opening 23 after external injection molding.

[0045] In a specific embodiment, a first opening 17 with a depth of 7 mm is set on the boss 16, and the height of the first connecting portion 15 is selected to be 5 mm.

[0046] The first opening 17 can be selected to have any cross-sectional shape, such as a circle, a triangle, a polygon, etc., and the first connecting portion 15 and the second connecting portion 22 are selected to have shapes matching the first opening 17.

The plurality of positioning posts 18 correspond to the plurality of positioning holes 24 one by one. When the skeleton and the control board assembly are assembled, the positioning posts 18 are respectively embedded in the corresponding positioning holes 24. In this embodiment, the positioning holes 24 can be selected as through holes.
