Description

Technical Field

[0001] This invention relates to the field of electric motors, and in particular to a stator assembly, an electric motor, and a washing device. Background Technology

[0002] The motor's lead wires are connected to the terminals, and the terminals are connected to the power cord via adapter cables. In related technologies, the lead wires and terminals can be connected by soldering. Before soldering, the lead wires need to be fixed to the terminals to prevent them from moving around. This pre-soldering fixation can be achieved using a clip-on method, where the lead wire is first clipped into the clip. However, with this method, due to manufacturing tolerances, the lead wires can easily become too loose or too tight, preventing them from fitting properly into the clip. This means the lead wires may lift up, making it difficult to adhere to the terminal and resulting in poor soldering quality. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a stator assembly that can reduce lead wire warping and improve the stability of lead wire and terminal connections.

[0004] The present invention also proposes an electric motor having the above-described stator assembly.

[0005] The present invention also proposes a washing device having the above-mentioned motor.

[0006] A stator assembly according to an embodiment of the present invention includes:

[0007] Insulating frame;

[0008] A winding is wound around the insulating frame, the winding including multiple leads;

[0011] The first terminal and the second terminal are respectively installed in the corresponding mounting positions. The first terminal and the second terminal are respectively connected to the lead wire. The first terminal includes a first wire bonding part and a first insert.

The winding is wound around the insulating frame, and multiple leads of the winding are connected to the first and second terminals respectively, for example, by welding, which can improve the stability of the connection between the leads and the first welding section. The first insert of the first terminal passes through the socket, thus facilitating the connection between the first insert and the power line to supply power to the winding. A first and second wire-clamping posts are spaced apart on one side of the first welding section of the first terminal.

A first and second clamping post are spaced apart on one side of the first welding section of the first terminal, allowing the leads to pass between them. A tooling is used to bend the first and / or second clamping posts toward the leads, further securing and clamping the leads, effectively reducing the possibility of the leads warping and facilitating subsequent connection between the leads and the first welding section. Therefore, compared to a snap-fit ​​method, fixing the leads by bending the first and / or second clamping posts is less affected by manufacturing tolerances, improving the stability of the connection between the leads and the first welding section and increasing production efficiency.

[0055] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0056] Reference Figure 1 As shown, a strip stator assembly 1000 of one embodiment of the present invention is obtained by connecting the ends. Figure 2 The annular stator assembly 1000 shown is an embodiment of the present invention. The stator assembly 1000 can reduce the warping of the lead wires 111 and improve the stability of the connection between the lead wires 111 and the terminals. It should be noted that, in addition to using a strip stator core 500, a modular stator core 500 can also be used; the appropriate solution should be selected based on the actual situation.

[0057] Reference Figure 3 and Figure 4As shown, in an embodiment of the present invention, the stator assembly 1000 includes a stator core 500, an insulating frame 100, a winding 110, a terminal block 120, a socket 130, a first terminal 200, and a second terminal 300. The insulating frame 100 is embedded in the stator core 500, and the winding 110 is wound around the insulating frame 100. The terminal block 120 can be connected to the insulating frame 100, for example, by integral injection molding, or by snap-fit, fasteners, welding, or other methods. The terminal block 120 has multiple mounting positions 121 spaced apart. The first terminal 200 and the second terminal 300 are respectively mounted in corresponding mounting positions 121. The socket 130 is connected to the terminal block 120 and covers the mounting positions 121. The first terminal 200 and the second terminal 300 are made of conductive material and are respectively connected to the leads 111 of the winding 110.

[0058] Reference Figure 4 As shown, the first terminal 200 includes a first bonding section 210 and a first insert 220. The first bonding section 210 is sheet-shaped and laid flat in the horizontal direction, while the first insert 220 is also sheet-shaped but arranged vertically. The first bonding section 210 and the first insert 220 can be directly connected or connected through the first mounting section 230. The first insert 220 protrudes from the socket 130 and can be directly connected to the power cord without needing a power adapter cable, thereby supplying power to the winding 110. A first wire-locking post 211 and a second wire-locking post 212 are spaced apart on one side of the first bonding section 210, as shown in the figure. Figure 5 As shown, the lead wire 111 is disposed between the first wire-locking post 211 and the second wire-locking post 212, and the first wire-locking post 211 and / or the second wire-locking post 212 can be bent toward the lead wire 111 to abut and engage with the lead wire 111, thereby restricting the position of the lead wire 111. It should be noted that the second terminal 300 includes a second wire bonding portion 310 and a second insert 320. One side of the second wire bonding portion 310 may also be provided with the same first wire-locking post 211 and second wire-locking post 212 as the first terminal 200, with similar shape, structure and function, and will not be described in detail here.

[0059] For example, the winding 110 is made of aluminum enameled wire with a diameter ≥ 0.4mm. The lead wire 111 of the enameled wire is guided to the first bonding section 210 by a winding needle and is located between the first wire clamping post 211 and the second wire clamping post 212. The tooling clamps the first wire clamping post 211 and the second wire clamping post 212 and bends them toward the lead wire 111 to limit the position of the lead wire 111, prevent the lead wire 111 from warping, and reduce the occurrence of displacement or misalignment of the lead wire 111. Then, the excess enameled wire is cut off, the enamel coating of the lead wire 111 at the first bonding section 210 is vaporized by a laser, and the robot arm solders the lead wire 111 after the enamel coating has been removed onto the first bonding section 210. It is understandable that since the first wire bonding section 210 is provided with a first wire holding post 211 and a second wire holding post 212, the solder can adhere to the first wire holding post 211 and the second wire holding post 212, thereby improving the stability of the solder bonding with the first wire bonding section 210 and reducing the situation of solder falling off.

[0060] Understandably, by employing the above-described solution, the tooling bends the first clamping post 211 and / or the second clamping post 212 toward the lead wire 111, thereby further securing and clamping the lead wire 111. This effectively reduces the likelihood of the lead wire 111 warping and facilitates the subsequent connection between the lead wire 111 and the first bonding section 210. Therefore, compared to a simple snap-fit ​​fixing method, the lead wire 111 is fixed by the bending deformation of the first clamping post 211 and / or the second clamping post 212, which is less affected by manufacturing tolerances and can improve the stability and production efficiency of the connection between the lead wire 111 and the first bonding section 210.

[0061] Reference Figure 6 As shown in the embodiment of the present invention, a support portion 213 is provided between the first wire-locking post 211 and the second wire-locking post 212. For example, the support portion 213 and the first wire-bonding portion 210 are integrally formed, and the support portion 213 is used to support the lead wire 111. When the first wire-locking post 211 and the second wire-locking post 212 are bent to restrict the position of the lead wire 111, the lead wire 111 is prone to tilting downwards if there is no support portion 213. Therefore, the support portion 213 is provided to support the lead wire 111. Through the cooperation of the first wire-locking post 211 and the second wire-locking post 212, the lead wire 111 can be further fixed, and the welding stability of the lead wire 111 and the first wire-bonding portion 210 can be improved.

[0062] When the stator assembly 1000 requires a small size and compact structure, meaning the distance between the first wire-locking post 211 and the second wire-locking post 212 is small, accurately positioning the lead wire 111 between the first and second wire-locking posts 211 is difficult due to equipment precision limitations. Using sensors or similar structures for positioning would be costly and structurally complex. Therefore, referring to... Figure 4 and Figure 6As shown in the embodiment of the present invention, the first wire-locking post 211 protrudes beyond the height of the first wire-bonding portion 210, which is higher than the height of the second wire-locking post 212 protruding beyond the height of the first wire-bonding portion 210. A first positioning surface 2111 is provided on the side of the first wire-locking post 211 facing the second wire-locking post 212. The first positioning surface 2111 is used to position the lead wire 111. When the lead wire 111 needs to be set, since the height of the first wire-locking post 211 is higher than that of the second wire-locking post 212, the lead wire 111 can first be positioned and engaged with the first positioning surface 2111 of the first wire-locking post 211. Then, the lead wire 111 is moved downwards between the first wire-locking post 211 and the second wire-locking post 212. The structure is simple, but it is accurate, efficient, and low-cost.

[0063] Reference Figure 4 and Figure 5 As shown in the embodiment of the present invention, the terminal block 120 is provided with a limiting groove 122. The limiting groove 122 is located on one side of the first welding section 210 and close to the winding 110. On the other side of the first welding section 210, there is a first wire-clamping post 211 and a second wire-clamping post 212, which are located away from the winding 110. Therefore, the lead wire 111 can first be clamped in the limiting groove 122, then pass through the first welding section 210, and finally pass between the first wire-clamping post 211 and the second wire-clamping post 212. With the above arrangement, the lead wire 111 and the first welding section 210 can be in contact, improving the stability of welding and the yield rate.

[0064] Reference Figure 8As shown, in an embodiment of the present invention, the terminal block 120 includes a limiting post 125. The limiting post 125 is located on the side of the first bonding wire portion 210 near the winding 110. A third wire-locking post 123 and a fourth wire-locking post 124 are spaced apart at the upper end of the limiting post 125, and a limiting groove 122 is formed between the third wire-locking post 123 and the fourth wire-locking post 124. Comparing with the same reference plane, the height of the third wire-locking post 123 is higher than that of the fourth wire-locking post 124, and a second positioning surface 1231 is provided on the side of the third wire-locking post 123 facing the fourth wire-locking post 124. Therefore, when arranging the lead wire 111, before engaging the lead wire 111 into the limiting groove 122, the lead wire 111 and the second positioning surface 1231 can be positioned and engaged first, and then the lead wire 111 can be moved downwards, so that the lead wire 111 is accurately engaged in the limiting groove 122, improving the engagement efficiency. It should be noted that the scheme of setting the second positioning surface 1231 on the third wire-locking post 123 can be used in conjunction with the scheme of setting the first positioning surface 2111 on the first wire-locking post 211. The positions of the third wire-locking post 123 and the first wire-locking post 211 are corresponding, that is, the first wire-locking post 211 is located on the left, the second wire-locking post 212 is located on the right, the third wire-locking post 123 is located on the left, and the fourth wire-locking post 124 is located on the right, so that the lead wire 111 can be smoothly locked in the limiting groove 122 and can smoothly pass between the first wire-locking post 211 and the second wire-locking post 212.

[0065] Reference Figure 3 and Figure 4 As shown in the embodiment of the present invention, the terminal block 120 is provided with three mounting positions 121 spaced apart along a first direction, which can be... Figure 4 The stator assembly 1000 also includes a third terminal 400, and the second terminal 300 and the third terminal 400 respectively include a second insert 320 and a third insert 420. The first terminal 200, the second terminal 300 and the third terminal 400 are sequentially mounted on three mounting positions 121 in the left-right direction, and the first terminal 200, the second terminal 300 and the third terminal 400 are spaced apart to avoid contact that could cause a short circuit. It should be noted that the winding 110 includes multiple leads 111, and the number of leads 111 corresponds to the number of terminals. For example, if the stator assembly 1000 includes a first terminal 200, a second terminal 300 and a third terminal 400, then there are also three leads 111, which are respectively connected to the first terminal 200, the second terminal 300 and the third terminal 400. It should also be noted that in another embodiment of the present invention, there may only be a first terminal 200 and a second terminal 300, that is, only two terminals are included, and the mounting position 121 can be changed to two, with the first terminal 200 and the second terminal 300 arranged at intervals and both mounted on the two mounting positions 121.

[0066] Understandably, since the first connector 220, the second connector 320, and the third connector 420 need to be connected and mated with the power cord, the spacing between the first connector 220, the second connector 320, and the third connector 420 is required to accommodate the structure of the power cord plug. For example, refer to... Figure 7 As shown, the distance between the middle of the first insert 220 and the middle of the second insert 320 is L1, satisfying 4mm ≤ L1 ≤ 6mm, for example, L1 is 5mm; the distance between the middle of the second insert 320 and the middle of the third insert 420 is L2, satisfying 4mm ≤ L2 ≤ 6mm, for example, L2 is 5mm. Therefore, the distance between the first insert 220, the second insert 320 and the third insert 420 is relatively narrow. When soldering the lead wire 111 to the first terminal 200, the second terminal 300 and the third terminal 400, the solder at adjacent soldering positions is prone to sticking together, resulting in a short circuit.

[0067] To solve the aforementioned problem of solder easily sticking together, refer to... Figure 6 As shown in the embodiment of the present invention, the first terminal 200 further includes a first mounting portion 230, which includes a first bent portion 231 and a second bent portion 232, both of which are strip-shaped. One end of the first bent portion 231 is connected to the side of the first bonding portion 210 near the second terminal 300. The other end of the first bent portion 231 is bent toward the second terminal 300 and connected to one end of the second bent portion 232. The other end of the second bent portion 232 extends toward a second direction and is connected to the first insert 220. The second direction can be... Figure 6 The front-back direction, that is, the second direction is perpendicular to the first direction. Among them, the first welding part 210, the first bending part 231, the second bending part 232 and the first insert 220 can be integrally formed.

[0068] Continue to refer to Figure 6 As shown, the second terminal 300 also includes a second bonding portion 310 and a second mounting portion 330. The second bonding portion 310 is sheet-shaped and laid flat in the horizontal direction. The second insert 320 is also sheet-shaped but extends in the vertical direction. The second mounting portion 330 is strip-shaped. One end of the second mounting portion 330 is connected to the side of the second bonding portion 310 away from the first terminal 200, and the other end of the second mounting portion 330 is connected to the second insert 320.

[0069] Continue to refer to Figure 6As shown, the third terminal 400 also includes a third bonding section 410 and a third mounting section 430. The third bonding section 410 is sheet-shaped and laid flat in the horizontal direction. The third insert 420 is also sheet-shaped but extends in the vertical direction. The third mounting section 430 is strip-shaped. One end of the third mounting section 430 is connected to the side of the third bonding section 410 near the second terminal 300, and the other end of the third mounting section is connected to the third insert 420. The third bonding section 410 may also have structures similar to the first terminal 200, such as the first wire-locking post 211, the second wire-locking post 212, and the support section 213. Therefore, the third bonding section 410 can be soldered to the lead wire 111, and its structure and function are similar to the first terminal 200, which will not be described in detail here.

[0070] The first terminal 200, the second terminal 300, and the third terminal 400 adopt the above-described structural layout, which allows the spacing between the first insert 220, the second insert 320, and the third insert 420 to be adapted to the structure of the power line. At the same time, it also ensures that the first soldering part 210, the second soldering part 310, and the third soldering part 410 are spaced a certain distance apart, effectively preventing the solder from sticking together at adjacent soldering positions during soldering, which could lead to a short circuit. This improves the safety and reliability of the stator assembly 1000.

[0071] Continue to refer to Figure 6 As shown in the embodiment of the present invention, the first insert 220, the second insert 320, and the third insert 420 are all provided with limiting holes 221, which are circular. Therefore, when the first insert 220, the second insert 320, and the third insert 420 are connected to the power cord plug, they can engage with the protruding structure of the plug to form a locking mechanism, improving the stability of the connection between the plug and the socket 130. It should be noted that in another embodiment of the present invention, the limiting hole 221 can also be replaced with a recess or similar structure, and a suitable solution can be selected according to the actual situation.

[0072] Reference Figure 8As shown in the embodiment of the present invention, the mounting position 121 is provided with a sealing groove 1211, a notch 1212, and a mounting groove 1213 in sequence along the direction away from the first bonding wire portion 210. The sealing groove 1211, the notch 1212, and the mounting groove 1213 are connected. In the left-right direction, the width of the sealing groove 1211 is smaller than the width of the notch 1212, and the width of the mounting groove 1213 is also smaller than the width of the notch 1212. When the first terminal 200 is installed, the first mounting portion 230 of the first terminal 200 and the sealing groove 1211 are interference-fitted. This prevents the molding material from entering the mounting groove 1213 during injection molding, thereby preventing the injection material from seeping out of the socket 130 along the first insert 220. The interference fit between the first insert 220 and the mounting groove 1213 restricts the position of the first terminal 200. Understandably, given the relatively long overall length of the sealing groove 1211, the notch 1212, and the mounting groove 1213, installation becomes more difficult when the first terminal 200 needs to be interference-fitted with the sealing groove 1211 and the mounting groove 1213. Therefore, a notch 1212 is provided to reduce the contact area between the first mounting part 230 and the mounting position 121, thereby reducing installation difficulty and improving production efficiency.

[0073] Reference Figure 6 As shown, in an embodiment of the present invention, a portion of the structure of the first insert 220 protrudes outward to form a plurality of spaced protrusions 222, for example... Figure 6 As shown, the two protrusions 222 are spaced apart along the front-to-back direction. Each protrusion 222 is formed by cutting a portion of the first insert 220 to make it protrude outwards; therefore, one side of the first insert 220 is concave, and the other side is convex. When the first insert 220 is placed in the mounting groove 1213, the protrusion 222 can spring back, allowing the first insert 220 to be smoothly placed in the mounting groove 1213. It can be understood that providing two protrusions reduces the likelihood of the first insert 220 rotating around one of the protrusions 222, thereby reducing the possibility of misalignment or swaying of the first insert 220.

[0074] Reference Figure 8 and Figure 9As shown in the embodiment of the present invention, the terminal block 120 has a first sealing surface 126 on the side facing the socket 130, and the socket 130 has a second sealing surface 134 on the side facing the terminal block 120. The second sealing surface 134 has a sealing protrusion 133. The stator assembly 1000 also includes a protective shell 131, which is connected to the terminal block 120. The protective shell 131 covers the first bonding wire portion 210, the second bonding wire portion 310, the third bonding wire portion 410, and the lead wire 111, and a plastic sealing space 132 is formed between the protective shell 131 and the terminal block 120. The protective shell 131 can also be connected to the socket 130, for example, by integral injection molding, which simplifies the assembly process. After the three leads 111 are respectively soldered to the first soldering part 210, the second soldering part 310 and the third soldering part 410, the terminal block 120 and the socket 130 are connected, the first sealing surface 126 and the second sealing surface 134 are sealed and fitted together, and the sealing protrusion 133 and the sealing groove 1211 are sealed and fitted together, and then plastic sealing can be performed.

[0075] Understandably, without the protective housing 131, during molding, the molding material, such as BMC material, would directly impact the first bonding section 210, the second bonding section 310, the third bonding section 410, and the lead wire 111, potentially causing the lead wire 111 to loosen. Therefore, the protective housing 131 protects the lead wire 111, effectively preventing the molding material from directly impacting it during molding, thus improving the connection stability between the lead wire 111 and its corresponding first bonding section 210, second bonding section 310, and third bonding section 410. Furthermore, the molding material can slowly flow into the molding space 132 through the gap between the protective housing 131 and the terminal block 120, further improving the connection stability between the lead wire 111 and its corresponding first bonding section 210, second bonding section 310, and third bonding section 410, and reducing the noise and temperature rise of the stator assembly 1000.

[0076] Continue to refer to Figure 8 and Figure 9As shown in the embodiment of the present invention, two positioning holes 127 are provided at intervals on the front end of the terminal block 120 facing the socket 130, and two positioning posts 135 are provided at intervals on the front end of the socket 130 facing the terminal block 120. The positions of the two positioning posts 135 correspond to the positions of the two positioning holes 127, thereby enabling the positioning posts 135 and positioning holes 127 to be positioned and engaged, facilitating quick determination of the position of the socket 130 relative to the terminal block 120 and improving assembly efficiency. It should be noted that in another embodiment of the present invention, the front end of the terminal block 120 may also have two positioning posts 135, and the front end of the socket 130 may have two positioning holes 127, with the positioning posts 135 and positioning holes 127 being positioned and engaged. It should also be noted that in another embodiment of the present invention, the number of positioning holes 127 and positioning posts 135 may also be one, three, four, etc., depending on the actual situation.

[0077] In an embodiment of the present invention, the first terminal 200, the second terminal 300, the third terminal 400, the terminal base 120, and the socket 130 can be an integral structure. That is, during the injection molding stage, the first terminal 200, the second terminal 300, the third terminal 400, the terminal base 120, and the socket 130 are injection molded together to simplify the assembly process and improve assembly efficiency. In another embodiment of the present invention, for example... Figure 4 As shown, the first terminal 200, the second terminal 300, the third terminal 400, and the socket 130 are all independent structures, which are then assembled together in the subsequent assembly stage. Using this approach, if the socket 130, terminal block 120, or other structures fail injection molding during the manufacturing stage, they can be directly melted down and recycled, facilitating reuse and reducing production costs.

[0078] An embodiment of the present invention provides a motor comprising the stator assembly 1000 described in the above embodiments. The motor can be a washing machine motor, a single-phase asynchronous motor, or the like. In this embodiment, the stator assembly 1000 is used. The first terminal 200 of the stator assembly 1000 is mounted at mounting position 121 of the terminal block 120. A winding 110 is wound around an insulating frame 100, and the lead wire 111 of the winding 110 can be connected to the first solder portion 210 of the first terminal 200, for example, by soldering, which improves the stability of the connection between the lead wire 111 and the first solder portion 210. A first insert 220 of the first terminal 200 protrudes from a socket 130, facilitating connection between the first insert 220 and a power cord to supply power to the winding 110. One end of the first wire bonding section 210 is provided with a first wire clamping post 211 and a second wire clamping post 212 spaced apart. Therefore, the lead wire 111 can be passed between the first wire clamping post 211 and the second wire clamping post 212. By using a tooling, the first wire clamping post 211 and / or the second wire clamping post 212 are bent toward the lead wire 111, thereby further fixing and clamping the lead wire 111, effectively reducing the possibility of the lead wire 111 warping, and facilitating the subsequent connection between the lead wire 111 and the first wire bonding section 210. Therefore, compared with the clamping method, the lead wire 111 is fixed by the bending deformation of the first wire clamping post 211 and / or the second wire clamping post 212, which is less affected by manufacturing tolerances and can improve the stability and production efficiency of the connection between the lead wire 111 and the first wire bonding section 210.

[0079] Since the motor adopts all the technical solutions of the stator assembly 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0080] A washing device according to one embodiment of the present invention includes the motor described in the above embodiments. The washing device can be a drum washing machine, a drum dryer, a top-loading washing machine, etc. The washing device of this embodiment uses the motor described in the above embodiments. A tooling is used to bend the first wire clamping post 211 and / or the second wire clamping post 212 toward the lead wire 111, thereby further fixing and clamping the lead wire 111, effectively reducing the possibility of the lead wire 111 warping, and facilitating the subsequent connection between the lead wire 111 and the first welding part 210. Therefore, compared to the clamping method, the lead wire 111 is fixed by the bending deformation of the first wire clamping post 211 and / or the second wire clamping post 212, which is less affected by manufacturing tolerances and can improve the stability and production efficiency of the connection between the lead wire 111 and the first welding part 210.
