Description

TECHNICAL FIELD

[0001] The utility model relates to motor equipment technical field, specifically, a kind of stator assembly, motor and washing equipment. BACKGROUND

[0002] Currently, the outgoing line of motor and terminal are connected, and the terminal and the adapter wire of power cord are connected. In the related art, the connection mode of outgoing line and terminal is generally welding, and the outgoing line needs to be fixed on the terminal before welding to avoid shaking around. Among them, the fixing before welding generally adopts the way of clamping groove clamping, i.e. clamping the outgoing line on the clamping groove.

[0003] However, due to manufacturing tolerance and other problems, the outgoing line is prone to be too tight to be clamped into the clamping groove, or to be damaged in the process of clamping into the clamping groove. In addition, the outgoing line is also prone to be too loose to affect the subsequent welding process, thereby affecting the welding effect and insulation reliability. SUMMARY

[0004] Embodiments of the utility model aim to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, the first aspect of the embodiments of the utility model provides a kind of stator assembly.

[0006] The second aspect of the embodiments of the utility model provides a kind of motor.

[0007] The third aspect of the embodiments of the utility model provides a kind of washing equipment.

[0008] Therefore, according to the first aspect of the embodiments of the utility model, a kind of stator assembly is provided, and the stator assembly includes: insulation frame;Stator winding, which is arranged on the insulation frame, and the stator winding includes outgoing line;Outgoing line seat, which is arranged on the insulation frame, and the outgoing line seat is provided with first limiting slot and second limiting slot, and the first limiting slot is closer to the insulation frame than the second limiting slot;Pin, which is arranged on the outgoing line seat, and the pin includes a connected welding part and a tab, part of the tab is exposed to the outgoing line seat, and the welding part is located between the first limiting slot and the second limiting slot, and the outgoing line passes through the first limiting slot and the second limiting slot respectively, and is connected with the welding part.

[0009] The stator assembly provided by the embodiment of the utility model includes insulating frame, stator winding, outgoing line seat and pin, specifically, the stator winding is arranged on the insulating frame, the stator winding includes outgoing line, optionally, the number of outgoing line is 3, it can be understood that the pin corresponds to the outgoing line one by one. Optionally, the stator assembly further includes stator core, and the stator core is arranged on the insulating frame. Optionally, the stator core is strip-shaped core. It can be understood that when the stator winding is wound on the insulating frame, the strip-shaped stator assembly can be bent under the action of the bending machine, and the beginning and the end are connected and welded together.

[0010] The outgoing line seat is arranged on the insulating frame, the pin is arranged on the outgoing line seat, the outgoing line is connected with the welding part of the pin, the insertion piece of the pin is exposed to the outgoing line seat, and the insertion piece can be connected with the connector of the whole washing equipment, that is, the outgoing line is electrically connected with the power supply through the pin.

[0011] The outgoing line seat is provided with the first limiting slot and the second limiting slot, and the first limiting slot is closer to the insulating frame than the second limiting slot, that is, the first limiting slot is located on the radial inner side of the second limiting slot. The welding part is located between the first limiting slot and the second limiting slot, and the outgoing line passes through the first limiting slot and the second limiting slot respectively, so as to limit the wire of the outgoing line before welding the outgoing line with the welding part, and realize the position fixation of the outgoing line before welding.

[0012] Since the first limiting slot and the second limiting slot are respectively located on the two sides of the radial direction of the welding part, after the outgoing line passes through the first limiting slot and the second limiting slot respectively, the outgoing line is straight under the limiting action of the first limiting slot and the second limiting slot, so as to realize the position fixation of the outgoing line on the welding part, and ensure the consistency and stability of the subsequent welding process.

[0013] In addition, compared with the position fixation of the outgoing line before welding by clamping in the related art, the effective position fixation of the outgoing line is realized, and the wire damage in the clamping process is avoided, so as to ensure the subsequent welding effect and improve the insulation reliability.

[0014] In addition, according to the stator assembly provided by the above technical scheme of the utility model, the following additional technical features are further provided:

[0015] In some technical schemes, optionally, along the radial direction of the stator winding, the first limiting slot is opposite to the second limiting slot.

[0016] In the technical scheme, since the first limiting slot and the second limiting slot are opposite in the radial direction, the outgoing line can be limited when the outgoing line is wired, so as to ensure that the outgoing line is straightened on the welding part, realize the position fixation of the outgoing line before welding, ensure the consistency and stability of the subsequent welding process, and improve the welding effect and electrical connection reliability.

[0017] In some embodiments, the pin further comprises a plurality of wire clamping posts, the plurality of wire clamping posts are arranged on the welding portion and located between the first limiting slot and the second limiting slot, at least two wire clamping posts are arranged at intervals to form a wire passing slot, the wire passing slot is in communication with the first limiting slot and the second limiting slot respectively, and the lead wire passes through the first limiting slot, the wire passing slot and the second limiting slot in sequence; wherein, along the circumferential direction of the stator winding, the width of at least one of the first limiting slot and the second limiting slot is smaller than the width of the wire passing slot.

[0018] In this embodiment, the pin further comprises a plurality of wire clamping posts, specifically, the plurality of wire clamping posts are arranged on the welding portion, and the plurality of wire clamping posts are located between the first limiting slot and the second limiting slot. By arranging the plurality of wire clamping posts, the tin beads can be flattened during the welding process of the lead wire, covering the enameled wire, effectively reducing the problems of partial welding and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly.

[0019] At least two wire clamping posts are arranged at intervals to form a wire passing slot, and any one of the first limiting slot and the second limiting slot is in communication with the wire passing slot. Since the plurality of wire clamping posts are located between the first limiting slot and the second limiting slot, that is, the wire passing slot is located between the first limiting slot and the second limiting slot. When the lead wire is routed, it passes through the first limiting slot, the wire passing slot and the second limiting slot in sequence.

[0020] The circumferential width of the first limiting slot is smaller than the circumferential width of the wire passing slot, or the circumferential width of the second limiting slot is smaller than the circumferential width of the wire passing slot, or the circumferential width of the first limiting slot is smaller than the circumferential width of the wire passing slot, and the circumferential width of the second limiting slot is smaller than the circumferential width of the wire passing slot, that is, the circumferential width of the wire passing slot is wider, and the circumferential width of the first limiting slot and the second limiting slot is narrower, so that when the lead wire is routed, the side surface of the lead wire only contacts the slot wall of the limiting slot, i.e. the wire outlet seat, except for the contact with the welding portion, avoiding the contact between the lead wire and the wire clamping post during the routing of the lead wire.

[0021] It can be understood that the pin is generally a metal stamping part, and generally has burrs at the edges of the wire clamping post. If the lead wire contacts the wire clamping post with burrs, the lead wire is easily damaged, reducing the insulation reliability of the stator assembly.

[0022] By making the circumferential width of the first limiting slot and / or the second limiting slot smaller than the width of the wire passing slot, the lead wire can be effectively prevented from contacting the wire clamping post during the routing of the lead wire, thereby avoiding damage to the lead wire by the wire clamping post with burrs, and improving the insulation reliability of the stator assembly.

[0023] In some embodiments, the plurality of clamping posts includes two first clamping posts and two second clamping posts, the two first clamping posts are respectively located on one side of the welding portion close to the first limiting slot, and the two second clamping posts are respectively located on one side of the welding portion close to the second limiting slot.

[0024] In this embodiment, the plurality of clamping posts includes two first clamping posts and two second clamping posts, specifically, the two first clamping posts are respectively located on one side of the welding portion close to the first limiting slot, and the two second clamping posts are respectively located on one side of the welding portion close to the second limiting slot, that is, the two first clamping posts and the two second clamping posts are respectively located on two sides of the welding portion in the radial direction.

[0025] Since the two first clamping posts and the two second clamping posts are respectively arranged on two sides of the welding portion in the radial direction, the tin beads can be guided to flow to the two sides, which is beneficial to uniformly lay the tin beads on the welding portion and cover the enameled wire, thereby effectively reducing the problems of partial soldering and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly.

[0026] The two first clamping posts are arranged at intervals to form a first wire passing slot, the first wire passing slot is in communication with the first limiting slot, the two second clamping posts are arranged at intervals to form a second wire passing slot, and the second wire passing slot is in communication with the second limiting slot. When the lead wire is routed, it sequentially passes through the first limiting slot, the first wire passing slot, the second wire passing slot and the second limiting slot. Since the circumferential width of the first wire passing slot and the second wire passing slot is relatively wide, and the circumferential width of the first limiting slot and the second limiting slot is relatively narrow, the lead wire can be effectively prevented from contacting the first clamping post and the second clamping post during the lead wire routing process, thereby avoiding damage to the lead wire by the clamping post with burrs, and improving the insulation reliability of the stator assembly.

[0027] In some embodiments, the wire outlet seat includes two first limiting posts and two second limiting posts, wherein the two first limiting posts are arranged at intervals to form a first limiting slot, and at least one first limiting post is opposite to the first clamping post; the two second limiting posts are arranged at intervals to form a second limiting slot, and at least one second limiting post is opposite to the second clamping post.

[0028] In this embodiment, the wire outlet seat includes two first limiting posts and two second limiting posts, specifically, the two first limiting posts are arranged at intervals to form a first limiting slot, and the two second limiting posts are arranged at intervals to form a second limiting slot. Since the plurality of clamping posts is located between the first limiting slot and the second limiting slot, that is, the two first clamping posts and the two second clamping posts are respectively located between the two first limiting posts and the two second limiting posts.

[0029] Since the at least one first limiting column is opposite to the first wire clamping column, and the at least one second limiting column is opposite to the second wire clamping column, the first limiting slot and the second limiting slot can limit the wire drawing of the lead-out wire, and the first limiting column and the second limiting column can also limit the welding part through the first wire clamping column and the second wire clamping column, thereby improving the assembly reliability between the pin and the lead-out seat, and the connection stability between the lead-out wire and the welding part, and further improving the electrical connection reliability of the stator assembly.

[0030] In some technical solutions, optionally, along the radial direction of the stator winding, there is a gap between the at least one first limiting column and the first wire clamping column, and / or there is a gap between the at least one second limiting column and the second wire clamping column.

[0031] In this technical solution, the first limiting column and the first wire clamping column have a gap in the radial direction, and / or the second limiting column and the second wire clamping column have a gap in the radial direction, that is, the first limiting column and the first wire clamping column are in clearance fit, and the second limiting column and the second wire clamping column are in clearance fit, thereby facilitating the assembly between the pin and the lead-out seat, and improving the assembly efficiency of the stator assembly.

[0032] In some technical solutions, optionally, along the axial direction of the stator winding, the at least one first limiting column is higher than the at least one second limiting column.

[0033] In this technical solution, since the axial height of the at least one first limiting column is higher than the axial height of the at least one second limiting column, that is, the axial height of the at least one first limiting column located on the inner side in the radial direction is higher, thereby the lead-out wire can be positioned by the at least one first limiting column when the lead-out wire is drawn, and the assembly efficiency of the stator assembly is further improved, and the cost of the stator assembly is reduced.

[0034] In some technical solutions, optionally, the pin further comprises a soldering column, the soldering column is arranged on the welding part and protrudes and extends towards the side where the lead-out wire is located, and the soldering column and the at least one wire clamping column are respectively located on different sides of the welding part.

[0035] In this technical solution, it is limited that the pin further comprises a soldering column, specifically, the soldering column is arranged on the welding part and protrudes and extends towards the side where the lead-out wire is located. It can be understood that during the process of welding the lead-out wire on the welding part, the soldering ball is easy to flow to one side, resulting in that the soldering ball cannot be evenly laid on the soldering surface, especially for aluminum enameled wire, the problems of partial welding and missing enameled wire are easy to occur during the welding process, which affects the electrical connection reliability of the stator assembly.

[0036] Due to the soldering column and the at least one wire clamping column being located at different sides of the welding portion respectively, the tin beads can be guided to flow in different directions, so that the tin beads are evenly laid on the welding portion and cover the enameled wire, effectively reducing the problems of offset welding and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly.

[0037] In addition, by arranging the soldering column, the enameled wire of the stator winding can be arranged as an aluminum enameled wire, which is conducive to reducing the production cost of the stator assembly while ensuring the welding effect.

[0038] In some technical solutions, optionally, the soldering column is arranged in a spaced manner with the at least one wire clamping column.

[0039] In the technical solution, since the soldering column is arranged in a spaced manner with the at least one wire clamping column, that is, there is a gap between the soldering column and the wire clamping column, the manufacturing difficulty of the pin is reduced, the production efficiency of the stator assembly is improved, and the production cost of the stator assembly is reduced.

[0040] In some technical solutions, optionally, the number of soldering columns is multiple, and at least two soldering columns are located at opposite sides of the welding portion.

[0041] In the technical solution, the number of soldering columns is limited to multiple, and specifically, at least two soldering columns are located at opposite sides of the welding portion. Since the soldering column and the wire clamping column are located at different sides of the welding portion, that is, the wire clamping column and the soldering column are arranged around the welding portion, respectively, during the welding process, the tin beads can be guided to flow around the welding portion, so that the tin beads are evenly laid on the welding portion and cover the enameled wire, further reducing the problems of offset welding and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly.

[0042] In addition, by arranging the soldering column, the enameled wire of the stator winding can be arranged as an aluminum enameled wire, which is conducive to reducing the production cost of the stator assembly while ensuring the welding effect.

[0043] In some technical solutions, optionally, the welding portion is provided with a welding surface, and the lead-out wire is connected with the welding surface; and in the axial direction of the stator winding, the slot bottom wall of at least one of the first limiting slot and the second limiting slot is lower than the welding surface.

[0044] In the technical solution, the welding portion is provided with a welding surface, and specifically, the lead-out wire is connected with the welding surface. Since in the axial direction of the stator winding, the slot bottom wall of at least one of the first limiting slot and the second limiting slot is lower than the welding surface, specifically, the slot bottom wall of the first limiting slot is lower than the welding surface, or the slot bottom wall of the second limiting slot is lower than the welding surface, or the slot bottom wall of the first limiting slot is lower than the welding surface, and the slot bottom wall of the second limiting slot is lower than the welding surface.

[0045] When the lead-out wire passes through the first limiting groove and the second limiting groove to limit the routing of the lead-out wire, the groove bottom wall of the first limiting groove and / or the second limiting groove is lower than the welding surface, so that the lead-out wire can be guaranteed to be attached to the welding surface, that is, when the lead-out wire is routed, the lead-out wire can be fully attached to the welding surface, which is beneficial to the consistency and stability of the subsequent welding process, improves the welding effect, and further improves the reliability of the stator assembly.

[0046] In some technical solutions, the wire outlet seat further has a supporting surface, the supporting surface is located between the first limiting groove and the second limiting groove, and at least a portion of the supporting surface is attached to the side of the welding portion that is away from the lead-out wire.

[0047] In this technical solution, the wire outlet seat further has a supporting surface, specifically, the supporting surface is arranged between the first limiting groove and the second limiting groove, the welding portion is arranged on the supporting surface, and the side of the welding portion that is away from the lead-out wire is attached to at least a portion of the supporting surface, that is, the bottom surface of the welding portion is attached to the supporting surface, which is beneficial to ensuring the assembly stability between the pin and the wire outlet seat, thereby improving the reliability of the stator assembly.

[0048] In some technical solutions, the wire outlet seat includes a seat body and a cover body, the seat body is connected to the insulating frame, the seat body is provided with the first limiting groove, the second limiting groove and the mounting groove, the cover body is arranged on the seat body, and the cover body is provided with the through hole; the insert piece includes a body and a mounting portion, the mounting portion is connected to the body and the welding portion respectively, at least a portion of the mounting portion is located in the mounting groove, and the body is exposed to the wire outlet seat through the through hole.

The cover body is provided with the through hole, and it can be understood that the number of the through hole corresponds to the number of the pin. The body of the insert piece is exposed to the wire outlet seat through the through hole, and it can be understood that the body is electrically connected to the power supply.

[0050] Optionally, the insert piece further includes a bending portion, and the two ends of the bending portion are connected to the mounting portion and the welding portion respectively.

Detailed Implementation

[0067] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0068] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0069] The following reference Figures 1 to 10 This invention describes a stator assembly 100, a motor, and a washing device provided according to some embodiments of the present invention.

[0070] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a stator assembly 100 is proposed, comprising: an insulating frame 110; a stator winding 120 disposed on the insulating frame 110, the stator winding 120 including a lead wire 121; a terminal block 130 disposed on the insulating frame 110, the terminal block 130 having a first limiting groove 131 and a second limiting groove 132, the first limiting groove 131 being closer to the insulating frame 110 than the second limiting groove 132; and a pin 140 disposed on the terminal block 130, the pin 140 including a welded portion 141 and a insert 142 connected together, a portion of the insert 142 being exposed outside the terminal block 130, the welded portion 141 being located between the first limiting groove 131 and the second limiting groove 132, the lead wire 121 passing through the first limiting groove 131 and the second limiting groove 132 respectively, and being connected to the welded portion 141.

[0071] The stator assembly 100 provided by the embodiment of the utility model includes an insulating frame 110, a stator winding 120, a wire outlet seat 130 and a pin 140, specifically, the stator winding 120 is arranged on the insulating frame 110, the stator winding 120 includes a lead-out wire 121, optionally, the number of the lead-out wire 121 is 3, it can be understood that the pin 140 corresponds to the lead-out wire 121 one by one, optionally, the stator assembly 100 further includes a stator core, the stator core is arranged on the insulating frame 110, optionally, the stator core is a strip-shaped core, it can be understood that when the stator winding 120 is wound on the insulating frame 110, the strip-shaped stator assembly 100 can be bent under the action of a bending machine, and the beginning and the end are connected and welded together.

[0072] The wire outlet seat 130 is arranged on the insulating frame 110, the pin 140 is arranged on the wire outlet seat 130, the lead-out wire 121 is connected with the welding part 141 of the pin 140, the insertion sheet 142 of the pin 140 is exposed to the wire outlet seat 130, and the insertion sheet 142 can be connected with the connector of the whole washing equipment, that is to say, the lead-out wire 121 is electrically connected with the power supply through the pin 140.

[0073] The wire outlet seat 130 is provided with a first limiting groove 131 and a second limiting groove 132, and the first limiting groove 131 is closer to the insulating frame 110 than the second limiting groove 132, that is to say, the first limiting groove 131 is located on the radial inner side of the second limiting groove 132. The welding part 141 is located between the first limiting groove 131 and the second limiting groove 132, and the lead-out wire 121 passes through the first limiting groove 131 and the second limiting groove 132 respectively, so as to limit the wire of the lead-out wire 121 before welding the lead-out wire 121 with the welding part 141, and realize the position fixation of the lead-out wire 121 before welding.

[0074] Since the first limiting groove 131 and the second limiting groove 132 are respectively located on the two sides of the radial direction of the welding part 141, after the lead-out wire 121 passes through the first limiting groove 131 and the second limiting groove 132 respectively, under the limiting action of the first limiting groove 131 and the second limiting groove 132, the lead-out wire 121 is in a straight line, so as to realize the position fixation of the lead-out wire 121 on the welding part 141, and ensure the consistency and stability of the subsequent welding process.

[0075] In addition, compared with the position fixation of the lead-out wire before welding by clamping in the related art, while realizing the effective position fixation of the lead-out wire 121, the situation that the lead-out wire 121 is damaged in the clamping process is avoided, so as to ensure the subsequent welding effect and improve the insulation reliability.

[0076] In some embodiments, optionally, the first limiting groove 131 is opposite to the second limiting groove 132 along the radial direction of the stator winding 120.

[0077] In this embodiment, since the first limiting groove 131 and the second limiting groove 132 are radially opposite, the lead wire 121 can be limited when it is being routed, ensuring that the lead wire 121 is laid flat on the welding part 141 in a straight line. This not only fixes the position of the lead wire 121 before welding, but also ensures the consistency and stability of subsequent welding processes, improving the welding effect and electrical connection reliability.

[0078] like Figure 6 As shown, in some embodiments, the pin 140 may optionally include a plurality of wire-clamping posts 143, which are disposed on the welding portion 141 and located between the first limiting groove 131 and the second limiting groove 132. At least two wire-clamping posts 143 are spaced apart to form a wire-passing groove 144, which is connected to the first limiting groove 131 and the second limiting groove 132 respectively. The lead wire 121 passes through the first limiting groove 131, the wire-passing groove 144 and the second limiting groove 132 respectively. Along the circumferential direction of the stator winding 120, the width of at least one of the first limiting groove 131 and the second limiting groove 132 is smaller than the width of the wire-passing groove 144.

[0079] In this embodiment, the pin 140 is further defined as including a plurality of wire-holding posts 143. Specifically, the plurality of wire-holding posts 143 are disposed on the welding part 141 and are located between the first limiting groove 131 and the second limiting groove 132. By setting the plurality of wire-holding posts 143, during the welding process of the lead wire 121, the solder balls can be guided to spread flat and cover the enameled wire, effectively reducing the problems of solder misalignment and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly 100.

[0080] At least two wire-clamping posts 143 are spaced apart to form a wire-passing groove 144. Either the first limiting groove 131 or the second limiting groove 132 communicates with the wire-passing groove 144. Since multiple wire-clamping posts 143 are located between the first limiting groove 131 and the second limiting groove 132, the wire-passing groove 144 is located between the first limiting groove 131 and the second limiting groove 132. When the lead wire 121 is routed, it passes sequentially through the first limiting groove 131, the wire-passing groove 144, and the second limiting groove 132.

[0081] The circumferential width of the first limiting groove 131 is less than the circumferential width of the wire passage groove 144, or the circumferential width of the second limiting groove 132 is less than the circumferential width of the wire passage groove 144, or the circumferential width of the first limiting groove 131 is less than the circumferential width of the wire passage groove 144, and the circumferential width of the second limiting groove 132 is less than the circumferential width of the wire passage groove 144. In other words, the circumferential width of the wire passage groove 144 is wider.

[0082] The second limiting groove 132 has a narrower circumferential width, so that when the lead wire 121 is running, in addition to contacting the welding part 141, the side of the lead wire 121 only contacts the groove wall of the limiting groove, i.e. the lead wire seat 130, thus avoiding the lead wire 121 from contacting the wire clamping post 143 when running.

[0083] It is understandable that the pin 140 is generally a metal stamping part, and there will usually be burrs at the edge of the wire clamping post 143. If the lead wire 121 comes into contact with the burr-filled wire clamping post 143, the lead wire 121 will be easily damaged, reducing the insulation reliability of the stator assembly 100.

[0084] By making the circumferential width of the first limiting groove 131 and / or the second limiting groove 132 smaller than the width of the through groove 144, the lead wire 121 can be effectively prevented from contacting the wire clamping post 143 during the routing of the lead wire 121, thereby preventing the lead wire 121 from being damaged by the burr-filled wire clamping post 143 and improving the insulation reliability of the stator assembly 100.

[0085] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the plurality of wire-locking posts 143 include two first wire-locking posts 145 and two second wire-locking posts 146. The two first wire-locking posts 145 are respectively located on the side of the welding part 141 near the first limiting groove 131, and the two second wire-locking posts 146 are respectively located on the side of the welding part 141 near the second limiting groove 132. The two first wire-locking posts 145 are spaced apart to form a first wire-passing groove 147, which communicates with the first limiting groove 131. The two second wire-locking posts 146 are spaced apart to form a second wire-passing groove 148, which communicates with the second limiting groove 132.

[0086] In this embodiment, a plurality of wire-locking posts 143 are defined, including two first wire-locking posts 145 and two second wire-locking posts 146. Specifically, the two first wire-locking posts 145 are respectively located on the side of the welding part 141 near the first limiting groove 131, and the two second wire-locking posts 146 are respectively located on the side of the welding part 141 near the second limiting groove 132. That is to say, the two first wire-locking posts 145 and the two second wire-locking posts 146 are respectively located on both sides of the welding part 141 in the radial direction.

[0087] Since two first wire-clamping posts 145 and two second wire-clamping posts 146 are respectively provided on both sides of the radial direction of the welding part 141, the solder balls can be guided to flow to both sides, which helps to make the solder balls evenly spread on the welding part 141, covering the enameled wire, thereby effectively reducing the problems of misaligned soldering and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly 100.

[0088] The two first clamping wire posts 145 are spaced apart to form a first wire passing groove 147, the first wire passing groove 147 is communicated with the first limiting groove 131, the two second clamping wire posts 146 are spaced apart to form a second wire passing groove 148, the second wire passing groove 148 is communicated with the second limiting groove 132, when the lead-out wire 121 is routed, it passes through the first limiting groove 131, the first wire passing groove 147, the second wire passing groove 148 and the second limiting groove 132 in sequence, since the circumferential width of the first wire passing groove 147 and the second wire passing groove 148 is wider, and the circumferential width of the first limiting groove 131 and the second limiting groove 132 is narrower, in the process of routing the lead-out wire 121, the lead-out wire 121 can be effectively prevented from contacting the first clamping wire post 145 and the second clamping wire post 146, so as to avoid the lead-out wire 121 being damaged by the clamping wire post 143 with burrs, and the insulation reliability of the stator assembly 100 is improved.

[0089] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, optionally, the wire outlet seat 130 includes two first limiting posts 133 and two second limiting posts 134, wherein the two first limiting posts 133 are spaced apart to form a first limiting groove 131, at least one first limiting post 133 is opposite to the first clamping wire post 145, the two second limiting posts 134 are spaced apart to form a second limiting groove 132, and at least one second limiting post 134 is opposite to the second clamping wire post 146.

[0090] In this embodiment, it is defined that the wire outlet seat 130 includes two first limiting posts 133 and two second limiting posts 134, specifically, the two first limiting posts 133 are spaced apart to form a first limiting groove 131, and the two second limiting posts 134 are spaced apart to form a second limiting groove 132, since the plurality of clamping wire posts 143 are located between the first limiting groove 131 and the second limiting groove 132, that is, the two first clamping wire posts 145 and the two second clamping wire posts 146 are located between the two first limiting posts 133 and the two second limiting posts 134 respectively.

[0091] Since the at least one first limiting column 133 is opposite to the first wire clamping column 145, and the at least one second limiting column 134 is opposite to the second wire clamping column 146, the first limiting slot 131 and the second limiting slot 132 can limit the wire routing of the lead-out wire 121, and the first limiting column 133 and the second limiting column 134 can also limit the welding portion 141 through the first wire clamping column 145 and the second wire clamping column 146, thereby improving the assembly reliability between the pin 140 and the wire outlet seat 130, and the connection stability between the lead-out wire 121 and the welding portion 141, and further improving the electrical connection reliability of the stator assembly 100.

[0092] In some embodiments, optionally, along the radial direction of the stator winding 120, the at least one first limiting column 133 and the first wire clamping column 145 have a gap, and / or the at least one second limiting column 134 and the second wire clamping column 146 have a gap.

[0093] In this embodiment, the first limiting column 133 and the first wire clamping column 145 have a gap in the radial direction, and / or the second limiting column 134 and the second wire clamping column 146 have a gap in the radial direction, that is, the first limiting column 133 and the first wire clamping column 145 are in clearance fit, and the second limiting column 134 and the second wire clamping column 146 are in clearance fit, so that the assembly between the pin 140 and the wire outlet seat 130 can be facilitated, and the assembly efficiency of the stator assembly 100 is improved.

[0094] As shown in Figure 3 , Figure 4 and Figure 5 , in some embodiments, optionally, along the axial direction of the stator winding 120, the at least one first limiting column 133 is higher than the at least one second limiting column 134.

[0095] In this embodiment, since the axial height of the at least one first limiting column 133 is higher than the axial height of the at least one second limiting column 134, that is, the axial height of the at least one first limiting column 133 located on the inner side in the radial direction is higher, so that when the lead-out wire 121 is routed, the lead-out wire 121 can be positioned by the at least one first limiting column 133, and the assembly efficiency of the stator assembly 100 is further improved, and the cost of the stator assembly 100 is reduced.

[0096] As shown in Figure 2 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, optionally, the pin 140 further comprises a soldering column 149, the soldering column 149 is arranged on the welding portion 141 and protrudes and extends towards the side where the lead-out wire 121 is located, and the soldering column 149 and the at least one wire clamping column 143 are respectively located on different sides of the welding portion 141.

[0097] In this embodiment, the pin 140 is defined to further include a soldering post 149, specifically, the soldering post 149 is arranged on the soldering portion 141 and extends outwards towards the side where the lead wire 121 is located. It can be understood that during the process of welding the lead wire 121 on the soldering portion 141, the tin beads are prone to flow to one side, resulting in that the tin beads cannot be evenly laid on the soldering surface, especially for the aluminum enameled wire, the problems of offset welding and missing enameled wire are prone to occur during the welding process, affecting the electrical connection reliability of the stator assembly 100.

[0098] Since the soldering post 149 and the at least one wire clamping post 143 are respectively located on different sides of the soldering portion 141, it is beneficial to guide the tin beads to flow in different directions, so that the tin beads are evenly laid on the soldering portion 141 and cover the enameled wire, effectively reducing the problems of offset welding and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly 100.

[0099] In addition, by arranging the soldering post 149, the enameled wire of the stator winding 120 can be arranged as an aluminum enameled wire, which is beneficial to reduce the production cost of the stator assembly 100 while ensuring the welding effect.

[0100] As shown in Figure 2 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, optionally, the soldering post 149 is arranged in a spaced manner with the at least one wire clamping post 143.

[0101] In this embodiment, since the soldering post 149 is arranged in a spaced manner with the at least one wire clamping post 143, that is, there is a gap between the soldering post 149 and the wire clamping post 143, it is beneficial to reduce the manufacturing difficulty of the pin 140, improve the production efficiency of the stator assembly 100, and reduce the production cost of the stator assembly 100.

[0102] As shown in Figure 2 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, optionally, the number of soldering posts 149 is multiple, and the at least two soldering posts 149 are respectively located on opposite sides of the soldering portion 141.

[0103] In this embodiment, the number of soldering posts 149 is defined as multiple, specifically, at least two soldering posts 149 are respectively located on the opposite sides of the welding portion 141. Since the soldering posts 149 and the clamping wire posts 143 are respectively located on different sides of the welding portion 141, that is, the clamping wire posts 143 and the soldering posts 149 are respectively arranged around the welding portion 141, during the welding process, the tin beads can be guided to flow around the welding portion 141, so that the tin beads are evenly laid on the welding portion 141 to cover the enameled wire, further reducing the problems of partial welding and missing enameled wire during soldering, and improving the electrical connection reliability of the stator assembly 100.

[0104] In addition, by arranging the soldering posts 149, the enameled wire of the stator winding 120 can be arranged as an aluminum enameled wire, which is conducive to reducing the production cost of the stator assembly 100 while ensuring the welding effect.

[0105] In some embodiments, the welding portion 141 is provided with a welding surface 150, and the lead wire 121 is connected to the welding surface 150; wherein, in the axial direction of the stator winding 120, the slot bottom wall 135 of at least one of the first limiting slot 131 and the second limiting slot 132 is lower than the welding surface 150.

[0106] In this embodiment, the welding portion 141 is provided with a welding surface 150, specifically, the lead wire 121 is connected to the welding surface 150. Since, in the axial direction of the stator winding 120, the slot bottom wall 135 of at least one of the first limiting slot 131 and the second limiting slot 132 is lower than the welding surface 150, specifically, the slot bottom wall 135 of the first limiting slot 131 is lower than the welding surface 150, or the slot bottom wall 135 of the second limiting slot 132 is lower than the welding surface 150, or the slot bottom wall 135 of the first limiting slot 131 is lower than the welding surface 150, and the slot bottom wall 135 of the second limiting slot 132 is lower than the welding surface 150.

[0107] When the lead wire 121 passes through the first limiting slot 131 and the second limiting slot 132 to limit the routing of the lead wire 121, since the slot bottom wall 135 of the first limiting slot 131 and / or the second limiting slot 132 is lower than the welding surface 150, it can be ensured that the lead wire 121 is attached to the welding surface 150, that is, when the lead wire 121 is routed, the lead wire 121 can be fully attached to the welding surface 150, which is conducive to the consistency and stability of the subsequent welding process, improves the welding effect, and further improves the reliability of the stator assembly 100.

[0108] As Figure 3 and Figure 4As shown in the drawings, in some embodiments, optionally, the wire outlet base 130 is further provided with a support surface 136, the support surface 136 is located between the first limiting groove 131 and the second limiting groove 132, and at least a part of the support surface 136 is fitted with a side surface of the welding portion 141 which is away from the lead-out wire 121.

[0109] In this embodiment, it is defined that the wire outlet base 130 is further provided with a support surface 136, specifically, the support surface 136 is arranged between the first limiting groove 131 and the second limiting groove 132, the welding portion 141 is arranged on the support surface 136, and a side surface of the welding portion 141 which is away from the lead-out wire 121 is fitted with at least a part of the support surface 136, that is, the bottom surface of the welding portion 141 is fitted on the support surface 136, which is beneficial to ensure the assembly stability between the pin 140 and the wire outlet base 130, thereby being beneficial to improve the reliability of the stator assembly 100.

[0110] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 , in some embodiments, optionally, the wire outlet base 130 includes a base body 137 and a cover body 138, wherein the base body 137 is connected with the insulating frame 110, the base body 137 is provided with the first limiting groove 131, the second limiting groove 132 and the mounting groove 139, the cover body 138 is arranged on the base body 137, and the cover body 138 is provided with the through hole 160; wherein the tab 142 includes a body 170 and a mounting portion 180, the mounting portion 180 is connected with the body 170 and the welding portion 141 respectively, at least a part of the mounting portion 180 is located in the mounting groove 139, and the body 170 is exposed to the wire outlet base 130 through the through hole 160.

[0111] In this embodiment, it is defined that the wire outlet base 130 includes a base body 137 and a cover body 138, specifically, the base body 137 is provided with the mounting groove 139, and the mounting portion 180 of the tab 142 is embedded in the mounting groove 139 to realize the assembly between the tab 142 and the wire outlet base 130. The cover body 138 is provided with the through hole 160, and it can be understood that the number of the through hole 160 corresponds to the number of the pin 140. The body 170 of the tab 142 is exposed to the wire outlet base 130 through the through hole 160, and it can be understood that the body 170 is electrically connected with the power supply.

[0112] Optionally, the tab 142 further includes a bending portion, two ends of the bending portion are connected with the mounting portion 180 and the welding portion 141 respectively.

[0113] Optionally, the cover body 138 is provided with a mounting column, and the base body 137 is provided with a mounting hole, the mounting column is inserted into the mounting hole to realize the assembly between the cover body 138 and the base body 137.

[0114] Optionally, the number of vias is 3. Since the number of pins 140 is 3, the body 170 of each pin 140 is exposed to the outlet seat 130 through one via 160.

[0115] Optionally, the insulating frame 110 is provided with a pin mounting groove (mounting groove 139), and the pin 140 is mounted in the pin mounting groove (mounting groove 139) of the insulating frame 110. The three outgoing wires 121 of the winding (stator winding 120) are connected to the three pins 140 respectively to realize electrical connection. The insulating frame 110 is provided with three pin mounting grooves (mounting grooves 139) which are distributed at intervals, and three pins are mounted in the mounting grooves 139 of the insulating frame 110.

[0116] In a specific embodiment, the pin 140 optionally includes a welding portion 141, a mounting portion 180, a tab (body 170), and a bending portion. The pin 140 is mounted in the pin mounting groove (mounting groove 139) of the insulating frame 110 through the mounting portion 180, and the tab (body 170) is connected to the connector of the washing machine to realize electrical connection. The welding portion 141 is about 90 degrees with the mounting portion 180, and the bending portion connects the mounting portion 180 and the welding portion 141.

[0117] The winding outgoing wire 121 passes through the welding portion 141 and is arranged on the pin welding surface (welding surface 150), and the welding surface (welding surface 150) is provided with a wire clamping column 143 at both ends, and each end has two wire clamping columns 143, which are a first wire clamping column and a second wire clamping column (two first wire clamping columns 145), a third wire clamping column and a fourth wire clamping column (two second wire clamping columns 146). The first wire clamping column and the second wire clamping column (two first wire clamping columns 145) form a wire passing groove (first wire passing groove 147), and the third wire clamping column and the fourth wire clamping column (two second wire clamping columns 146) form a wire passing groove (second wire passing groove 148). The enameled wire (outgoing wire 121) passes through the first wire clamping groove (first wire passing groove 147) and the second wire clamping groove (second wire passing groove 148) respectively. The purpose of the wire clamping groove (wire passing groove 144) is to stack tin, guide the tin beads to be flat, and cover the column enameled wire. In addition, the wire clamping groove (wire passing groove 144) can also limit the enameled wire to ensure that the enameled wire is pulled flat in a straight line.

[0118] If there is no tin plating column (soldering column 149) on the left and right sides of the soldering surface (welding surface 150), the tin beads may be offset during soldering on the left and right sides, that is, the tin is stacked to one side.

[0119] By providing an auxiliary soldering column (soldering column 149) on the left and right sides of the pin soldering surface (welding surface 150), the problem of offset soldering and missing enameled wire during soldering is reduced. During the soldering process, the tin column is evenly laid on the soldering surface, effectively reducing the proportion of offset soldering and missing enameled wire during soldering.

[0120] Optionally, an auxiliary soldering column (soldering column 149) is arranged on both sides of the soldering surface (soldering surface 150), and the auxiliary soldering column (soldering column 149) has a gap with the surrounding wire clamping column 143 for production. Optionally, an auxiliary soldering column is arranged on one side of the bending part, and two auxiliary soldering columns are arranged on the other side. This is conducive to further evenly laying soldering beads on the pin soldering surface (soldering surface 150), and reducing the problem of partial soldering and missing lacquered wires.

[0121] The insulating frame 110 is composed of a wire winding support part and a pin mounting part (wire outlet seat 130). The pin mounting part (wire outlet seat 130) is located above the wire winding support part. The wire winding support part is provided with a winding (stator winding 120) for winding and insulation.

[0122] The pin mounting part (wire outlet seat 130) is used for mounting the pins 140 and fixing the winding lead-out wire 121. The pin mounting part (wire outlet seat 130) is provided with a pin mounting groove (mounting groove 139), a pin support part (support surface 136) and a wire stopping column (first limiting column 133 and second limiting column 134). The pin mounting part (mounting part 180) is mounted in the pin mounting groove (mounting groove 139), and the pin soldering part (soldering part 141) is mounted on the pin support part (support surface 136). The pin support part (support surface 136) is provided with a wire stopping column on both sides, and the wire stopping column protrudes from the support part plane. Each side has two wire stopping columns, which are two first limiting columns 133 and two second limiting columns 134.

[0123] The two first limiting columns 133 form a first wire passing groove (first limiting groove 131) opposite to each other, and the two second limiting columns 134 form a second wire passing groove (second limiting groove 132) opposite to each other. The winding lead-out wire 121 passes through the first wire passing groove (first limiting groove 131) and the second wire passing groove (second limiting groove 132) in sequence, and the two grooves are in front of and behind the winding lead-out wire 121, and are in a straight line. The position of the winding lead-out wire 121 on the pin 140 is fixed, which ensures the consistency and stability of the subsequent soldering process.

[0124] The bottom plane (groove bottom wall 135) of the first wire passing groove (first limiting groove 131) and the second wire passing groove (second limiting groove 132) is set to be slightly lower than the pin soldering surface (soldering surface 150), which is conducive to ensuring that the winding lead-out wire 121 is attached to the pin soldering surface (soldering surface 150) when passing through the wire, and is conducive to the consistency and stability of the subsequent soldering process.

[0125] The pin 140 is mounted on the insulating frame 110, and a pin welding portion (welding portion 141) is arranged on a pin supporting portion (supporting surface 136) of the insulating frame 110. Four wire clamping columns 143 of the pin 140 are located inside an area formed by four wire clamping columns (two first limiting columns 133 and two second limiting columns 134) of the insulating frame 110. The first wire clamping column, the second wire clamping column (two first wire clamping columns 145), the third wire clamping column, and the fourth wire clamping column (two second wire clamping columns 146) are respectively arranged on the first wire clamping column, the second wire clamping column (two first limiting columns 133), the third wire clamping column, and the fourth wire clamping column (two second limiting columns 134).

[0126] The first wire passing groove (first limiting groove 131) and the second wire passing groove (second limiting groove 132) of the insulating frame 110 have a width smaller than that of the first wire passing groove 147 and the second wire passing groove 148 of the pin 140, and the first wire passing groove (first limiting groove 131) and the second wire passing groove (second limiting groove 132) of the insulating frame 110 are respectively located in the first wire passing groove 147 and the second wire passing groove 148 of the pin 140 as viewed from the wire passing plane of the winding lead wire 121, so that the winding lead wire 121 passes through the first wire passing groove (first limiting groove 131) of the insulating frame 110, the first wire passing groove 147 of the pin 140, the second wire passing groove 148 of the pin 140, and the second wire passing groove (second limiting groove 132) of the insulating frame 110 in sequence during winding, and the side surface is only in contact with the insulating frame (wire outlet seat 130) except for the bottom surface and the pin welding surface (welding surface 150), and is not in contact with the wire clamping column 143 of the pin 140. The reason is that the pin 140 is a metal stamping part, and it is difficult to ensure that there is no burr at the edge of the wire clamping column 143, and the winding lead wire 121 is easily damaged during winding, thereby reducing the insulation reliability of the motor.
