Description

Technical Field

[0001] The utility model relates to the field of motor stators, in particular to a motor stator structure. Background Art

[0002] Due to the axial space limitation of ultra-thin notebook computer fans, it is difficult to locate the U, V, W, and COM solder joints of the motor, which increases the difficulty of manufacturing. The current practice in the industry is to rely on workers to manually pull the enameled wire to align the solder joints. This operation is not only difficult, but also extremely challenging. It requires the operator to have good eyesight and rich experience, and it is difficult to achieve through automated production, so the production process takes a long time.

[0003] like Figures 1A to 1D As shown, it is the application number TW105101150 of Taiwan, China, which discloses a stator assembly of a motor, and the stator assembly includes a stator core (silicon steel sheet) 11, at least one winding coil 12, a circuit board assembly 13, a metal column 14 and a sleeve portion 15. The stator core 11 includes a plurality of poles 111. At least one winding coil 12 is wound on the plurality of poles 111 of the stator core 11, and the winding coil 12 includes at least one wire outlet 121. The metal column 14 includes a first end face and a second end face, wherein the first end face faces upward, and the second end face is attached to the circuit board assembly 13. The sleeve portion 15 partially covers the metal column 14 and includes a plurality of petals 151, wherein a groove 152 is formed between two adjacent petals 151. When the wire-outlet portion 121 of the winding coil 12 passes through at least two grooves 152 , the wire-outlet portion 121 of the winding coil 12 is bridged over the first end surface of the metal column 14 .

[0004] However, the conventional utility model still needs to be operated manually, in which the wire outlet 121 of the winding coil 12 is manually pulled through at least two corresponding grooves 152, and then bypasses one or two petals 151 to the left or right from the outside, and then passes through two opposite grooves 152. After that, bypass one or two petals 151 to the left or right from the other outside again, and pass through another two opposite grooves 152, and finally bind the wire outlet 121 to the braid 151. Since the process depends entirely on cumbersome manual operations and different manual experiences, the winding method or force may be different or uneven, causing the wire outlet 121 to break or loosen easily. What's more, the inefficient operation of multiple windings and tying to the petals 151 makes the entire winding process time-consuming and cannot be completed quickly, affecting production efficiency, and cannot be applied to automated production.

[0005] Therefore, how to solve the above problems and deficiencies is the direction that the designers of this case and the relevant manufacturers engaged in this industry are eager to study and improve. Utility Model Content

DETAILED DESCRIPTION

[0023] The above-mentioned purpose and the structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings.

[0024] Please refer to Figure 2 It is a three-dimensional schematic diagram of the utility model; Figure 3 for Figure 2 A partial enlarged schematic diagram of Figure 4A-4B is a schematic diagram of a wire clamping member; Figure 5A-Figure 5B It is a schematic diagram of the lead-out line segment sliding from the sliding-in portion into the clamping portion.

[0025] like Figure 2 and Figure 3 As shown, the utility model relates to a motor stator structure 20, which includes a silicon steel sheet group 21, an insulating frame group 22 and a winding group 23. The silicon steel sheet group 21 is composed of a plurality of silicon steel sheets stacked and sandwiched between the insulating frame group 22. The insulating frame group 22 includes a first insulating frame 221 and a second insulating frame 222 respectively located on the upper and lower sides of the silicon steel sheet group 21, so that the silicon steel sheet group 21 is fixed between the first and second insulating frames 221, 222.

[0026] In addition, the insulating frame assembly 22 further includes a clamping unit which is integrally formed with the insulating frame assembly 22 or is a separate component. In this embodiment, the clamping unit has at least one clamping component 3 and a matching component 25, and it can be optionally arranged on the first insulating frame 221 or the second insulating frame 222.

[0027] As shown in the figure, the matching component 25 includes a notch 251 formed on the first insulating frame 221 , and the notch 251 has two opposite inner walls 253 ; two spaced-apart clamping arms 252 are disposed in the notch 251 .

[0028] The clamping member 3 is disposed in the notch 251; in this embodiment, a movable U-shaped member (or other shaped member) is used for illustration. Figure 4A-4B The clamping member 3 has a clamping portion 31 clamped and fixed by the two clamping arms 252, and two arms 32 extending outward from the two ends of the clamping portion 31. The two arms 32 are spaced apart and parallel to each other, and are respectively close to the two inner walls 253 of the notch 251. Furthermore, a sliding portion 321 is respectively provided at one or both of the upper and lower edges of the two arms 32, and a clamping portion 322 is provided between the two sliding portions 321. The sliding portion 321 can be, for example but not limited to, an inclined surface, a chamfer or other means for guiding the sliding in, and the clamping portion 322 can be, for example but not limited to, a groove. Furthermore, in a preferred embodiment, the clamping member 3 is an elastomer made of an elastic material (including but not limited to silicone, rubber, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU) or other synthetic elastic materials), and has the function of elastic deformation and recovery.

[0029] The winding assembly 23 has a winding section 231 wound around the silicon steel sheet assembly 21 and the insulating frame assembly 22, and at least one lead-out line segment 232 located at the end of the winding section 231, which extends toward the outside of the insulating frame assembly 22. In this embodiment, for example but not limited to, the winding assembly 23 has three lead-out line segments 232 representing the three phases U, V, and W, respectively, and one lead-out line segment 232 serving as a common connection terminal (COM).

[0030] Continue as Figure 5A and Figure 5B As shown, one of the lead-out segments 232 is used for illustration, so that the lead-out segment 232 corresponds to between one of the arms 32 of the clamping member 3 and one of the inner walls 253 of the matching member 25. When the lead-out segment 232 moves from top to bottom, the sliding portion 321 at the upper edge of the arm 32 slides toward the clamping portion 322, so as to push the sliding portion 321 of the clamping member 3 to temporarily displace and deform (elastic deformation), leaving the inner wall 253 and allowing the lead-out segment 232 to slide into the clamping portion 322. After the lead-out segment 232 slides into the clamping portion 322, the sliding portion 321 of the clamping member 3 returns to its original state (elastic recovery) and abuts against the inner wall 253, so that the lead-out segment 232 is firmly fixed by the clamping portion 322. In this way, not only can the lead-out wire segment 232 be positioned quickly and accurately, but it can also ensure that the wire body of the lead-out wire segment 232 is firmly tightened (supported) to facilitate subsequent welding operations with the circuit board.

[0031] Please continue to refer to Fig. 6A and Figure 6BThis is a schematic diagram of the present invention being connected to a circuit board. As shown in the figure, a circuit board 40 is assembled with the motor stator structure 20 of the present invention. A surface 41 of the circuit board 40 is provided with a plurality of welding positions 42. The motor stator structure 20 is disposed on the surface 41 of the circuit board 40, and its first insulating frame 221 faces the surface 41 of the circuit board 40. Each lead-out line segment 232 of the motor stator structure 20 is precisely aligned with each welding position 42 of the circuit board 40, thereby completing the welding fixation between the two.

[0032] By means of the above structure, the lead wire segment 232 of the winding assembly 23 is fastened by the wire clamping unit of the insulating frame assembly 22, which can not only quickly and accurately locate at a predetermined position to reduce the positioning time, but also ensure that the wire body is stable and tight, thereby facilitating accurate alignment of the welding position 42 of the overlapping circuit board 40. In addition, the utility model is also conducive to automated production, so as to effectively improve the shortcomings of manual operation in traditional technology, and improve manufacturing efficiency and product reliability.
