However, it is easy to understand that the present invention provides many suitable concepts and can be implemented in a wide variety of specific contexts. The specific embodiments disclosed are only used to illustrate the use of the present invention in a specific way, and are not intended to limit the scope of the present invention.

[0094] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meanings as commonly understood by those skilled in the art to which this disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0095] Figure 1 Schematic diagram of a motor mechanism M according to an embodiment of the present invention. Figure 2 is a schematic diagram of the motor mechanism M at another viewing angle, and Figure 3 for Figure 1 The cross-sectional view along the AA direction. Figures 1 to 3 As shown, the motor mechanism M in this embodiment mainly includes a metal base 100, a snap element 200, a silicon steel sheet assembly 300, an insulating element 400, a shaft assembly 500, a rotating element 600, a driving assembly 700, a hollow frame 800, a housing 900 and a fan blade K. The driving assembly 700 can drive the shaft assembly 500 to rotate relative to the hollow frame 800 and the housing 900, and the fan blade K can be connected to the shaft assembly 500, so that it can be driven to rotate together. Specifically, the motor mechanism M can be set in a vehicle, a ship, an aircraft, or other equipment that needs to rotate the fan blade K, but is not limited thereto.

[0096] See also Figures 3 to 5 The metal base 100 may include a seat 110 and a plurality of protrusions 120. The seat 110 generally has a disc-shaped structure, and the protrusions 120 are connected to the seat 110 and protrude from an upper surface 111 of the seat 110. A plurality of stop structures 121 may be formed at one end of the protrusion 120 not connected to the seat 110.

[0097] The buckle element 200 can be formed on the metal base 100 by insert molding. In detail, the buckle element 200 may include an annular portion 210 and a plurality of buckle portions 220. The annular portion 210 covers the periphery of the seat portion 110 of the metal base 100, and the buckle portion 220 protrudes from the upper surface 111 of the seat portion 110 and has a hook-shaped structure. In this embodiment, the buckle portions 220 may be connected to each other, the protrusion 120 is adjacent to the buckle portion 220, and each protrusion 120 of the metal base 100 may be disposed between two buckle portions 220, so that at least a portion of each protrusion 120 may be covered by the buckle element 200. For example, the buckle element 200 may be made of plastic, but is not limited thereto.

[0098] See also FIG. 6A to FIG. 6C , the silicon steel sheet assembly 300 may include a first silicon steel sheet 310 and a second silicon steel sheet 320. The first silicon steel sheet 310 may include a first body 311, a plurality of first pole teeth 312, and a plurality of positioning protrusions 313. The first body 311 has an annular structure, and thus it may have a first central hole H1. The first pole teeth 312 are connected to the first body 311 and extend outward from the first body 311. In this embodiment, each first pole tooth 312 has a T-shaped structure, and the spacing between adjacent first pole teeth 312 is the same. The positioning protrusions 313 are formed on the inner wall surface of the first central hole H1, and each positioning protrusion 313 is respectively formed with a positioning hole 314. In this embodiment, the positioning protrusions 313 are further connected through the reinforcing ring 315 of the first silicon steel sheet 310 to enhance the structural strength of the first silicon steel sheet 310.

[0099] The second silicon steel sheet 320 includes a second body 321 and a plurality of second pole teeth 322. The second body 321 has an annular structure, so it can have a second central hole H2. The second pole teeth 322 are connected to the second body 321 and extend outward from the second body 321. In this embodiment, each second pole tooth 322 has a T-shaped structure, and the spacing between adjacent second pole teeth 322 is the same.

[0100] like Fig. 6AAs shown, when the motor mechanism M is assembled, the second silicon steel sheet 320 can be stacked on the first silicon steel sheet 310 to form the aforementioned silicon steel sheet assembly 300. Since the shapes and sizes of the first body 311 and the second body 321 are substantially the same, and the number, shape and size of the first pole teeth 312 and the second pole teeth 322 are also substantially the same, when the second silicon steel sheet 320 is stacked on the first silicon steel sheet 310, the first body 311 and the second body 321 can be aligned with each other, and the first pole teeth 312 and the second pole teeth 322 can also be aligned with each other. Since no convex portion corresponding to the positioning convex portion 313 is formed in the second center hole H2 of the second silicon steel sheet 320, the second center hole H2 of the second silicon steel sheet 320 exposes the positioning convex portion 313 in the axial direction.

[0101] See also Figure 3 and Figure 7 , the insulating element 400 can connect or even cover the first body 311, the second body 321, the first pole tooth 312 and the second pole tooth 322 of the silicon steel sheet assembly 300, and can further have a cylindrical portion 410 accommodated in the first central hole H1 and the second central hole H2. The cylindrical portion 410 has a third central hole H3, and the minimum size of the third central hole H3 can be less than or equal to the maximum size of the first central hole H1 and the maximum size of the second central hole H2. In this embodiment, when the minimum size of the third central hole H3 is less than the maximum size of the first central hole H1 and the maximum size of the second central hole H2, the protrusion 120 of the metal base 100 and the buckle portion 220 of the buckle element 200 can be located between the third central hole H3 and the first body 311.

[0102] Figure 8 for Figure 1 The cross-sectional view along the BB direction. Figure 3 and Figure 8 As shown, when the motor mechanism M is assembled, the protrusion 120 of the metal base 100 can be inserted into the positioning hole 314 on the first silicon steel sheet 310, and the stopping structure 121 at its end can be accommodated in the second center hole H2. It should be particularly noted that the aforementioned stopping structure 121 can extend in a direction away from the positioning hole 314, and can even be pressed together by a special jig, and the aforementioned stopping structure 121 can be unfolded in a Y shape. Through the aforementioned method, the stopping structure 121 can overlap with the positioning protrusion 313 not only in the Z-axis direction, and the silicon steel sheet assembly 300 can be fixed on the metal base 100. In addition, the snap-on portion 220 of the snap-on element 200 can also be snapped onto the insulating element 400, thereby enhancing the fixing effect of the silicon steel sheet assembly 300 and the insulating element 400.

[0103] The shaft assembly 500 may include a shaft 510 and a plurality of bearings 520. The shaft 510 and the bearings 520 are both disposed in the third central hole H3, and the shaft 510 may be connected to the insulating element 400 via the bearings 520. The rotating element 600 is connected to the shaft 510, and the fan blades K are also connected to the shaft 510, so that the shaft 510, the rotating element 600 and the fan blades K may rotate synchronously.

[0104] See also Fig. 9 In this embodiment, a plurality of first holes 610 and a plurality of second holes 620 are formed on the rotating element 600. In the radial direction, the distance D1 between the first hole 610 and the rotating shaft 510 is smaller than the distance D2 between the second hole 620 and the rotating shaft 510. In particular, in the radial direction, each first hole 610 can overlap with at least two second holes 620, thereby reducing the volume generated when the motor mechanism M is in operation and reducing the overall weight of the motor mechanism M.

[0105] Please go back Figure 3 , the driving component 700 may include one or more coils 710 and one or more magnetic elements 720. The coil 710 may be wound around the first pole tooth 312 and the second pole tooth 322. Since the first pole tooth 312 and the second pole tooth 322 are coated with the insulating element 400, the coil 710 and the first and second pole teeth 312, 322 are separated by the insulating element 400, that is, the coil 710 will not directly contact the first and second pole teeth 312, 322, so as to avoid the problem of short circuit. The magnetic element 720 may be arranged on the rotating element 600, and its position may correspond to the position of the coil 710. In this embodiment, the magnetic element 720 has a circular ring structure.

[0106] When current flows into the coil 710 , the electromagnetic interaction between the coil 710 and the magnetic element 720 can generate a driving force, so that the rotating element 600 rotates, and further drives the rotating shaft 510 and the fan blades K to rotate synchronously.

[0107] The hollow frame 800 can surround the aforementioned metal base 100, the buckle element 200, the silicon steel sheet assembly 300, the insulating element 400, the shaft assembly 500, the rotating element 600 and the driving assembly 700 to prevent the aforementioned elements from being damaged by collision with external objects. The housing 900 can be arranged on one side of the metal base 100 and can be connected to the hollow frame 800 to avoid electrostatic discharge (ESD) and electromagnetic interference (EMI). In the present embodiment, the hollow frame 800 may also have a locking hole and / or a cooling channel connected to an external device, but is not limited thereto.

[0108] like Fig.10 As shown, in this embodiment, a shock absorbing element S connected to the hollow frame 800 and the housing 900 may be provided between the hollow frame 800 and the housing 900. The shock absorbing element S may be formed on the buckle element 200 located on the periphery of the metal base 100 by embedded injection molding. The shock absorbing element S may include rubber, for example. Since the buckle element 200 is mainly composed of plastic, the shock absorbing element S may be tightly attached to the buckle element 200. In addition, the buckle element 200 may also perform the motor body balancing function. When the motor M is assembled as a whole, the balancing operation may also be performed by combining the outside of the three buckle elements with the balancing jig.

[0109] When the hollow frame 800 and the housing 900 are connected, the shock-absorbing element S can fill the gap between the hollow frame 800 and the housing 900, thereby achieving a waterproof effect. In addition, since the shock-absorbing element S includes rubber, the vibration generated when the motor mechanism M operates can be reduced.

[0110] See also Figure 2 and Fig.11 In this embodiment, the housing 900 may have a hole 901, and the position of the hole 901 may correspond to the position of the rotating shaft 510. A cantilever structure N may be connected to the housing 900 and accommodated in the hole 901, and the hole 901 may be filled with a sealing element L. The cantilever structure N may include metal, so that the arm portion N1 of the cantilever structure N may be flexible, and the free end N2 of the cantilever structure N may have sufficient rigidity. In some embodiments, the cantilever structure N and the housing 900 may be integrally formed.

[0111] The sealing element L in the hole 901 may be flexible. For example, the sealing element L may include rubber, but is not limited thereto. The sealing element L may contact the lower surface of the arm portion N1 of the cantilever structure N. In this way, even if the arm portion N1 of the cantilever structure N has a large fluctuation or a large range of movement, the sealing element L can still completely seal the hole 901 to achieve a waterproof effect.

[0112] When the cantilever structure N is in the preset position ( Fig.11 ), a distance G may be spaced between the cantilever structure N and the rotating shaft 510. For example, the aforementioned distance G may be between 1 mm and 3 mm (e.g., 2 mm), but is not limited thereto. During the assembly of the motor mechanism M, the user may apply force to the free end N2 of the cantilever structure N, so that the free end N2 is deformed and moves toward the rotating shaft 510, and then the rotating shaft 510 may be pushed so that the rotating shaft 510 moves to the desired position. Afterwards, the user may stop applying force to the cantilever structure N, and the cantilever structure N may return to the aforementioned preset position. Therefore, when the motor mechanism M is operating, the cantilever structure N will not affect the rotation of the rotating shaft 510.

[0113] See also Figure 2 as well as Fig. 12A In this embodiment, the hollow frame 800 has a plurality of first joint structures 810, 820, 830, 840, the housing 900 has a plurality of second joint structures 910, 920, 930, 940, and a connection port T is disposed on the housing 900. The hollow frame 800 and the housing 900 can be detachably combined with each other through the first joint structures 810, 820, 830, 840 and the second joint structures 910, 920, 930, 940, and the connection port T can be oriented in different directions.

[0114] For example, in Fig. 12A In the embodiment, the first bonding structure 810 is connected to the second bonding structure 910, the first bonding structure 820 is connected to the second bonding structure 920, the first bonding structure 830 is connected to the second bonding structure 930, and the first bonding structure 840 is connected to the second bonding structure 940. At this time, the connection port T may face a first direction R1.

At this time, the connection port T may face a second direction R2, and the second direction R2 is different from the first direction R1.

[0116] exist Fig. 12C In the embodiment, the first bonding structure 810 is connected to the second bonding structure 930, the first bonding structure 820 is connected to the second bonding structure 940, the first bonding structure 830 is connected to the second bonding structure 910, and the first bonding structure 840 is connected to the second bonding structure 920. At this time, the connection port T may face a second direction R2', and the second direction R2' is different from the first direction R1.

At this time, the connection port T may face a second direction R2", and the second direction R2" is different from the first direction R1.

[0118] Therefore, through the aforementioned structure, the user can adjust the direction of the connection port T of the motor mechanism M according to the needs, so it is convenient for the installation and connection of the motor mechanism M.

[0119] In addition, if FIG. 12A to FIG. 12DAs shown, in this embodiment, the housing 900 may include a plurality of positioning protrusions 950, and the shock-absorbing element S may include a plurality of positioning grooves S1.
