[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0032] In the present invention, unless otherwise specified, directional words such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0033] In order to solve the problem in the prior art that the windings on the insulating frame are exposed and easily scratched and damaged, the present application provides a stator frame, a stator and a motor.

[0034] like Figures 1 to 7 As shown, the stator frame includes a frame body 10, a puncture assembly 20, and a wiring cover plate 40. The frame body 10 has a winding recess 11, and the winding recess 11 has a wire entry port 111. The puncture assembly 20 is disposed in the winding recess 11 and includes at least two puncture structures 21 spaced apart along the circumference of the frame body 10. Each puncture structure 21 includes a plurality of serrated segments 211 spaced apart along the radial and / or height directions of the frame body 10. Each serrated segment 211 is tilted downward with the serrated side facing the wire entry port 111 to puncture the surface layer of the enameled wire entering through the wire entry port 111. The wiring cover plate 40 includes a wiring portion 42, which has a metal connecting pin 43 and is disposed outside the puncture assembly 20. The wiring cover plate 40 contacts the wire whose surface layer has been punctured by the serrated segments 211.

[0035] By applying the technical solution of this embodiment, the enameled wire is wound in the winding recess 11 after the surface layer is pierced by the serrated segment 211 of the piercing structure 21. Since the wiring cover 40 is in contact with the wire whose surface layer is pierced by the serrated segment 211, the above-mentioned wire can be directly connected to the outside world through the metal connecting pin 43 of the wiring cover 40.

[0036] Compared with the prior art in which the wiring is routed in the corresponding wire grooves on the outer wall of the insulating frame, the windings wound on the stator frame in this embodiment are built into the frame body 10, thereby completing the closure of the docking wires, effectively isolating the wires from the outside world, avoiding the risk of collision and abrasion, and thus solving the problem in the prior art that the windings on the insulating frame are exposed to the outside and are prone to abrasion and damage, thereby ensuring the normal operation of the stator.

[0037] In this embodiment, the puncturing assembly 20 includes two puncturing structures 21 spaced apart along the circumference of the skeleton body 10 , and each puncturing structure 21 includes a plurality of serrated segments 211 spaced apart along the radial and height directions of the skeleton body 10 .

[0038] In other embodiments not shown in the drawings, each piercing structure includes a plurality of sawtooth segments spaced apart along the radial direction of the skeleton body.

[0039] In other embodiments not shown in the drawings, each puncturing structure includes a plurality of sawtooth segments spaced apart along the height direction of the skeleton body.

[0040] It should be noted that the number of puncture structures 21 in the puncture assembly 20 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, three, four, five, or more puncture structures 21 are provided in the puncture assembly 20.

[0041] Optionally, a first mating portion 112 is provided on the inner surface of the winding recess 11. The piercing assembly 20 further includes a body 22 having at least two mounting recesses 221, each corresponding to one of the at least two piercing structures 21. Each piercing structure 21 is positioned within its corresponding mounting recess 221. A second mating portion 23 is provided on the body 22. One of the first mating portion 112 and the second mating portion 23 is a convex portion, while the other is a concave portion. The convex portion extends into the concave portion and engages with the concave portion to facilitate assembly between the body 22 and the winding recess 11. This arrangement not only makes the piercing assembly 20 more compact, achieving a miniaturized stator frame design, but also allows for greater flexibility in the structural selection of the first mating portion 112 and the second mating portion 23 to meet different usage requirements and operating conditions, enhancing operator flexibility.

[0042] like Figure 3 As shown, the body 22 has two mounting recesses 221, which are arranged one-to-one with the two puncturing structures 21. Each puncturing structure 21 is arranged in its corresponding mounting recess 221. In this way, the above arrangement makes the structure of the puncturing assembly 20 simpler, easier to manufacture and implement, and reduces the processing cost and difficulty of the puncturing assembly 20.

[0043] It should be noted that the number of the mounting recesses 221 in the body 22 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the body 22 has three, four, five, or more mounting recesses 221 .

[0044] In this embodiment, the first matching portion 112 is a recessed portion, and the second matching portion 23 is a convex portion. The convex portion extends into the recessed portion and is positionally engaged with the recessed portion to achieve assembly of the body 22 and the winding recess 11 .

[0045] In other embodiments not shown in the drawings, the first matching portion is a convex portion, and the second matching portion is a concave portion. The convex portion extends into the concave portion and is limitedly engaged with the concave portion to achieve assembly of the body and the winding concave portion.

[0046] In this embodiment, an accommodating space is formed between the lowest serrated segment 211 of each puncturing structure 21 and the inner surface of the mounting recess 221 , and the accommodating space is used to accommodate the wire formed after the puncturing structure 21 punctures the surface layer.

[0047] Optionally, there are multiple winding recesses 11 and multiple puncture assemblies 20, and the multiple puncture assemblies 20 are arranged in a one-to-one correspondence with the multiple winding recesses 11. At least one accommodation space in each puncture assembly 20 is used to accommodate the winding input wire 31, and at least another accommodation space is used to accommodate the winding output wire 32. In this way, the above arrangement ensures that the puncture assembly 20 located in one winding recess 11 is used to accommodate different windings, so as to wind the stator frame.

[0048] In this embodiment, one accommodating space in each puncturing assembly 20 is used to accommodate the winding incoming wire 31, and the other accommodating space is used to accommodate the winding outgoing wire 32.

[0049] In this embodiment, the puncture assembly 20 is an integrally formed structure. This configuration not only improves the structural stability and service life of the puncture assembly 20, but also reduces the processing cost and difficulty of the puncture assembly 20.

[0050] Optionally, each mounting recess 221 is a U-shaped groove, and the piercing structure 21 corresponding to the U-shaped groove includes at least two serrated segment groups spaced apart along the radial direction of the frame body 10, with at least one serrated segment group disposed on one wall of the U-shaped groove, and at least another serrated segment group disposed on the other wall of the U-shaped groove. Each serrated segment group includes a plurality of serrated segments 211 spaced apart along the height of the frame body 10. This arrangement not only makes the structural layout of the at least two serrated segment groups more rational and compact, but also improves the piercing assembly 20's efficiency in piercing the surface layer of the enameled wire, ensuring that the pierced surface layer of the wire can conduct electricity with the metal connecting pin 43.

[0051] In this embodiment, the piercing structure 21 includes two serrated segments spaced apart along the radial direction of the stator frame body 10. One serrated segment set is positioned on one wall of the U-shaped slot, and the other serrated segment set is positioned on the other wall of the U-shaped slot. This arrangement simplifies the structure of the piercing assembly 20, making it easier to manufacture and implement, and reduces the cost and difficulty of manufacturing the stator frame.

[0052] It should be noted that the number of the serrated segment groups in the puncture structure 21 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the puncture structure 21 includes three, four, five, or more serrated segment groups.

[0053] like Figure 1 and Figure 5 As shown, the skeleton body 10 has a central hole, and the wiring cover 40 also includes a first plate 41. The first plate 41 is positioned within the central hole and conforms to the inner surface of the central hole. The wiring portion 42 is disposed on the first plate 41 and engages with the skeleton body 10. This arrangement further ensures that the wires are internally contained within the skeleton body 10, thereby sealing the connection wires. Furthermore, this arrangement allows the wiring cover 40 to be detachably connected to the skeleton body 10, facilitating replacement and maintenance of the wiring cover 40.

[0054] Specifically, the above arrangement makes the wiring cover 40 an independent structure, which can be replaced according to different wiring methods of the motor, thereby achieving the universalization of the winding and the skeleton body, which is conducive to the universalization of the motor production process.

[0055] like Figure 2 As shown, the wiring portion 42 includes a bent plate body and a second plate body 424. The bent plate body has a first bent plate segment 421, a second bent plate segment 422 and a third bent plate segment 423 that are arranged in sequence. The first bent plate segment 421 is connected to the second bent plate segment 422 through a metal connecting pin 43, and the second bent plate segment 422 is connected to the third bent plate segment 423 through another metal connecting pin 43. Both ends of the first bent plate segment 421, the second bent plate segment 422 and the third bent plate segment 423 are respectively connected to the first plate body 41 and the second plate body 424. The second plate body 424 is snap-connected to the skeleton body 10. In this way, the above-mentioned arrangement makes the structure of the wiring portion 42 simpler, easier to process and implement, and reduces the processing cost and difficulty of the wiring portion 42.

[0056] In this embodiment, the connecting portion 42 is an integrated structure.

[0057] like Figure 2As shown, the side of the second plate 424 away from the bent plate has a winding wire slot 425 and a winding wire slot 426. Thus, the winding wire slot 425 and the winding wire slot 426 are used to fix and limit the winding wire 31 and the winding wire 32, respectively, thereby preventing the wires from moving or swaying and affecting the winding stability.

[0058] In this embodiment, the number of the winding recesses 11 is equal to the number N of the stator slots.

[0059] Optionally, the built-in wiring modes of the wiring cover plate 40 include but are not limited to: Y-type series wiring, series-parallel wiring, parallel wiring, △-type series wiring, series-parallel wiring and parallel wiring.

[0060] In this embodiment, after the stator core and the frame body 10 are assembled, enameled wire is wound into the stator core slots and onto the stator frame, securing the two together as a single unit. After winding each slot, the inlet and outlet wire ends of the winding for that slot are inserted into two adjacent piercing assemblies 20, so that the wire ends in each piercing assembly 20 serve as the outlet wire ends for the previous slot and the inlet wire ends for the next slot.

[0061] The present application also provides a stator (not shown) comprising the above-mentioned stator frame.

[0062] The present application also provides a motor (not shown) comprising the above-mentioned stator.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] The stator frame includes a frame body, a puncture assembly and a wiring cover plate. The frame body has a winding recess, and the winding recess has a wire entry port. The puncture assembly is arranged in the winding recess. The puncture assembly includes at least two puncture structures spaced apart along the circumference of the frame body. Each puncture structure includes a plurality of serrated segments spaced apart along the radial and / or height directions of the frame body. Each serrated segment is tilted downward and the side with the serrations faces the wire entry port to puncture the surface layer of the enameled wire entering from the wire entry port. The wiring cover plate includes a wiring portion, which has a metal connecting pin and is covered outside the puncture assembly. In this way, the enameled wire is wound in the winding recess after the surface layer is punctured by the serrated segment of the puncture structure. Since the wiring cover plate is in contact with the wire whose surface layer is punctured by the serrated segment, the above-mentioned wire can be directly connected to the outside through the metal connecting pin of the wiring cover plate.

[0065] Compared with the prior art in which the wiring is routed in the corresponding wire grooves on the outer wall of the insulating frame, the windings wound on the stator frame in this application are built into the frame body, thereby completing the closure of the docking wires, effectively isolating the wires from the outside world, avoiding the risk of collision and abrasion, and thus solving the problem in the prior art that the windings on the insulating frame are exposed to the outside and are prone to abrasion and damage, ensuring the normal operation of the stator.
