Description

Technical Field

[0061] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0063] In the description of the present utility model, "a plurality of" refers to more than two. If the first and second are described only for the purpose of distinguishing technical features, they cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0064] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0065] This application provides a motor, which is mainly applied to a laundry treatment device. Among them, the laundry treatment device may include, but is not limited to, electrical appliances such as washing machines, dryers, and washer-dryers. Hereinafter, the dryer will be mainly used as an example for detailed description.

[0066] When the laundry treatment device is a dryer, it includes a drum and a blower wheel. Among them, the blower wheel is arranged in the air duct system of the dryer, and the blower wheel is configured to rotate to provide the power to drive the air flow, so as to blow the heated hot air in the air duct system into the drum. The drum is used to accommodate the clothes to be dried, and the drum is configured to rotate to drive the clothes contained therein to continuously tumble, so that the hot air blown into the drum can fully contact each piece of clothing.

[0067] For some dryers, the drum and the blower wheel are driven by the same drive shaft, so the rotation directions of the blower wheel and the drum are always the same. When the drum rotates in reverse, the blower wheel also rotates in reverse. At this time, the air volume generated by the blower wheel is very weak, resulting in a reduction in the hot air flow entering the drum and affecting the drying efficiency of the dryer.

[0068] Please refer to Figure 1 , Figure 1 which is a cross-sectional view of the motor according to an embodiment of the present utility model. In the embodiment of this application, the motor 10 includes a first motor 100 and a second motor 200. The first motor 100 includes a first drive shaft 130, and the first drive shaft 130 is connected to the blower wheel of the dryer. The second motor 200 includes a second drive shaft 230, and the second drive shaft 230 is connected to the drum of the dryer.

[0069] Specifically, during the operation of the dryer, the first drive shaft 130 of the first motor 100 drives the wind wheel to rotate, and the second drive shaft 230 of the second motor 200 drives the drum to rotate. That is, the drum and the wind wheel are driven by different drive shafts respectively, and the rotation of the drum and the rotation of the wind wheel are independent of each other. Then, when the second motor 200 drives the drum to rotate in reverse, the wind wheel can still maintain its original rotation direction under the drive of the first motor 100, ensuring the air volume of the drum, so that the reverse rotation of the drum will not affect the flow of hot air entering the drum, thereby improving the drying efficiency of the dryer and reducing energy consumption. It has been verified that under the same clothing capacity, the drying time of the dryer using the motor 10 of the present application can be reduced by 15% - 30%.

[0070] Please refer to Figure 1 and Figure 2 , Figure 2 which is an exploded view of the motor according to an embodiment of the present utility model. The first motor 100 includes a first stator assembly 110, a first rotor assembly 120, and the above-mentioned first drive shaft 130. The first stator assembly 110 is sleeved outside the first rotor assembly 120, that is, the first stator assembly 110 is arranged around the first rotor assembly 120. The first drive shaft 130 passes through the first rotor assembly 120 and is fixedly connected to the first rotor assembly 120. Under the action of the magnetic field, the first rotor assembly 120 can be driven to rotate relative to the first stator assembly 110, and the first rotor assembly 120 drives the first drive shaft 130 to rotate, thereby driving the wind wheel to rotate.

[0071] The second motor 200 includes a second stator assembly 210, a second rotor assembly 220, and the above-mentioned second drive shaft 230. The second stator assembly 210 is sleeved outside the second rotor assembly 220, that is, the second stator assembly 210 is arranged around the second rotor assembly 220. The second drive shaft 230 passes through the second rotor assembly 220 and is fixedly connected to the second rotor assembly 220. Under the action of the magnetic field, the second rotor assembly 220 can be driven to rotate relative to the second stator assembly 210, and the second rotor assembly 220 drives the second drive shaft 230 to rotate, thereby driving the drum to rotate.

[0072] Since different motors are provided to be connected to the drum and the wind wheel respectively, to reduce the occupation of the internal space of the dryer, the first motor 100 and the second motor 200 can be assembled into an integral body.

[0073] Please refer to Figure 1 and Figure 2, the first stator assembly 110 includes a first plastic-sealed housing 111, the first rotor assembly 120 is rotatably arranged within the first plastic-sealed housing 111, the first motor 100 includes a first end cover 140, and the first end cover 140 is connected to the first plastic-sealed housing 111. The second stator assembly 210 includes a second plastic-sealed housing 211, the second rotor assembly 220 is rotatably arranged within the second plastic-sealed housing 211, the second end cover 240 is connected to the second plastic-sealed housing 211, the second motor 200 includes the second end cover 240, and the second end cover 240 is connected to the second plastic-sealed housing 211, and the first end cover 140 is connected to the second end cover 240, thereby connecting the first motor 100 and the second motor 200 into an integral whole. Among them, the first end cover 140 includes a first positioning mechanism, the second end cover 240 includes a second positioning mechanism, and the first positioning mechanism is in positioning cooperation with the second positioning mechanism so that the first motor 100 and the second motor 200 are coaxially arranged, that is, the axis of the first drive shaft 130 coincides with the axis of the second drive shaft 230.

[0074] Specifically, during the assembly process of the motor 10, the first motor 100 and the second motor 200 are first assembled independently. Specifically, through the connection between the first plastic-sealed housing 111 and the first end cover 140, the first stator assembly 110, the first rotor assembly 120 and the first drive shaft 130 are assembled into an integral whole. Similarly, through the connection between the second plastic-sealed housing 211 and the second end cover 240, the second stator assembly 210, the second rotor assembly 220 and the second drive shaft 230 are assembled into an integral whole, obtaining the complete first motor 100 and the second motor 200. Then, by connecting the first end cover 140 and the second end cover 240, the first motor 100 and the second motor 200 are assembled into one. Then, three assembly lines can be configured on the production line of the motor 10. The first assembly line is used to assemble the first motor 100, the second assembly line is used to assemble the second motor 200, and the third assembly line is used to assemble the first motor 100 and the second motor 200 together. These three assembly lines can be carried out synchronously, that is, the three assembly lines are parallel. Compared with assembling the components on the first motor 100 and the components on the second motor 200 together in the form of loose parts (on one assembly line), the assembly efficiency is effectively improved, and the production efficiency can be improved.

[0075] Moreover, in the present utility model, by providing a first positioning mechanism on the first end cover 140 and a second positioning mechanism on the second end cover 240, while connecting the first end cover 140 and the second end cover 240, the first end cover 140 and the second end cover 240 are also positioned through the first positioning mechanism and the second positioning mechanism. Furthermore, coaxial positioning of the first motor 100 and the second motor 200 can be achieved. Using the same component for connection and positioning simplifies the assembly and further improves the assembly efficiency.

[0076] In one embodiment, please refer to Figure 3 and Figure 4 , Figure 3 which is a schematic structural view of the first end cover according to an embodiment of the present utility model, Figure 4 and

[0077] which is a schematic structural view of the second end cover according to an embodiment of the present utility model. The first positioning mechanism 142 includes a first positioning portion 1421, and the second positioning mechanism 242 includes a second positioning portion 2421. When the first end cover 140 is connected to the second end cover 240, the first positioning portion 1421 is positioned on at least one side in the circumferential direction of the second positioning portion 2421. The positioning cooperation between the two can limit the relative movement of the first end cover 140 and the second end cover 240 in at least one direction to achieve positioning in at least one direction.

[0078] Please combine Figure 3 、 Figure 4 and Figure 5 and Figure 6 , Figure 5 which is a cross-sectional view of the first end cover according to an embodiment of the present utility model, Figure 6 and

[0079] which is a cross-sectional view of the second end cover according to an embodiment of the present utility model. The first positioning portion 1421 includes a first sub-positioning portion 1421a. The first sub-positioning portion 1421a is positioned on the side of the second positioning portion 2421 away from the second cover body 241, so that the first end cover 140 and the second end cover 240 are positioned and cooperated in the first direction. The first direction is the extending direction of the second positioning portion 2421. Taking the second cover body 241 designed as a disc as an example, the first direction is the radial direction of the second cover body 241. When the second end cover 240 is positioned and cooperated with the first end cover 140, the first sub-positioning portion 1421a restricts the freedom of movement of the second positioning portion 2421 in the radial direction of the second cover body 241, that is, restricts the relative movement of the second end cover 240 in its radial direction.The first positioning portion 1421 may further include a second sub-positioning portion 1421b, and the second sub-positioning portion 1421b is positioned on one side of the second positioning portion 2421 along its extending direction, so that the first end cover 140 and the second end cover 240 are positioned and cooperated along a second direction, and the second direction is the circumferential direction of the second cover body 241. Still taking the second cover body 241 designed in a disc shape as an example, the second sub-positioning portion 1421b limits the freedom degree of the second positioning portion 2421 moving along the circumferential direction of the second cover plate body, that is, limits the relative movement of the second end cover 240 along its circumferential direction.

[0080] In one embodiment, as Figure 3 shown, the number of the second sub-positioning portions 1421b is two, and the two second sub-positioning portions 1421b are respectively located on both sides of the second positioning portion 2421 along its extending direction. The first sub-positioning portion 1421a and the two second sub-positioning portions 1421b enclose a first positioning groove, and the second positioning portion 2421 is positioned in the first positioning groove. The first sub-positioning portion 1421a and the two second sub-positioning portions 1421b realize three-sided positioning of the second positioning portion 2421.

[0081] In one embodiment, the first positioning mechanism 142 further includes a third positioning portion 1423, and the second positioning mechanism 242 further includes a fourth positioning portion 2422. The fourth positioning portion 2422 is positioned on at least one side of the circumferential direction of the third positioning portion 1423. Similarly, the positioning and cooperation of the two can limit the relative movement of the first end cover 140 and the second end cover 240 along at least one direction to realize positioning in at least one direction.

[0082] Please refer to Figures 3 to 6 , the third positioning portion 1423 is connected to the outer peripheral edge of the first cover body 141 and extends in a direction away from the first cover body 141. The second end cover 240 includes a second connecting portion 2423. The second connecting portion 2423 is connected to the outer peripheral edge of the second cover body 241, and the fourth positioning portion 2422 is arranged on the side of the second connecting portion 2423 facing the first end cover 140.

[0083] The fourth positioning portion 2422 includes a third sub-positioning portion 2422a, and the third sub-positioning portion 2422a is positioned on the side of the third positioning portion 1423 away from the first cover body 141, so that the first end cover 140 and the second end cover 240 are positioned and cooperated along a third direction, and the third direction is the extending direction of the third positioning portion 1423. Taking the first cover body 141 designed in a disc shape as an example, the third direction is the radial direction of the first cover body 141. When the first end cover 140 and the second end cover 240 are positioned and cooperated, the third sub-positioning portion 2422a limits the relative movement of the third positioning portion 1423 along the radial direction of the first cover body 141, that is, limits the relative movement of the first end cover 140 along its radial direction.

[0084] The fourth positioning portion 2422 may further include a fourth sub-positioning portion 2422b. The fourth sub-positioning portion 2422b is positioned on one side of the third positioning portion 1423 along its extending direction, so that the first end cover 140 and the second end cover 240 are positioned and cooperated in the fourth direction, and the fourth direction is the circumferential direction of the first cover body 141. Still taking the first cover body 141 designed as a disc type as an example, the fourth sub-positioning portion 2422b limits the degree of freedom of the third positioning portion 1423 to move along the circumferential direction of the first cover plate body, that is, limits the relative movement of the first end cover 140 along its circumferential direction.

[0085] In an embodiment, as Figure 4 shown, the number of the fourth sub-positioning portions 2422b is two. The two fourth sub-positioning portions 2422b are respectively located on both sides of the fourth positioning portion 2422 along its extending direction. The third sub-positioning portion 2422a and the two fourth sub-positioning portions 2422b enclose a second positioning groove, and the third positioning portion 1423 is positioned in the second positioning groove. The third sub-positioning portion 2422a and the two fourth sub-positioning portions 2422b achieve three-sided positioning of the third positioning portion 1423.

[0086] It can be understood that the number of the second positioning portions 2421 can be multiple, and the number of the third positioning portions 1423 can also be multiple. Among them, on the first end cover 140, the first positioning portion 1421 and the multiple third positioning portions 1423 are evenly distributed along the circumferential direction of the first cover body 141. On the second end cover 240, the fourth positioning portion 2422 and the multiple second positioning portions 2421 are evenly distributed along the circumferential direction of the second cover body 241. In this case, the interval angles of the uniform arrangement of the first positioning portion 1421 and the multiple third positioning portions 1423 are the same as the interval angles of the uniform arrangement of the fourth positioning portion 2422 and the multiple second positioning portions 2421. In this way, the first positioning portion 1421 of the first end cover 140 can be positioned and cooperated with any one of the second positioning portions 2421 on the second end cover 240. Similarly, the fourth positioning portion 2422 of the second end cover 240 can be positioned and cooperated with any one of the third positioning portions 1423 on the first end cover 140, improving the convenience of assembly.

[0087] To further improve production efficiency, in an embodiment, the first end cover 140 and the second end cover 240 are configured to have the same structure.

[0088] Among them, the fourth positioning portion 2422 on the second end cover 240 has the same structure as the first positioning portion 1421 of the first end cover 140, and the third positioning portion 1423 on the first end cover 140 has the same structure as the second positioning portion 2421 on the second end cover 240. Then, when assembling the first motor 100 and the second motor 200 respectively, there is no need to distinguish between the first end cover 140 and the second end cover 240, which improves the error tolerance rate during the assembly process of the motor 10, improves the assembly efficiency, and further improves the production efficiency. Moreover, the main body parts of the first end cover 140 and the second end cover 240 are injection molded parts, and the first end cover 140 and the second end cover 240 can be processed and formed using the same mold, reducing the number of forming molds required during the production process of the motor 10 components and effectively reducing the production cost.

[0089] Please refer to Figure 7 , Figure 7 is a schematic diagram of the positioning process of the first end cover and the second end cover of the embodiment of the present invention. Specifically, since the first end cover 140 and the second end cover 240 have the same structure, when positioning the first end cover 140 and the second end cover 240, turn one of the end covers over so that the first end cover 140 and the second end cover 240 are face to face, and then rotate one of the end covers by a certain angle, which is the interval angle between the first positioning portion 1421 and the third positioning portion 1423 (also the interval angle between the fourth positioning portion 2422 and the second positioning portion 2421), so that the first positioning mechanism 142 and the second positioning mechanism 242 can be aligned.

[0090] In an embodiment, the structures of the first rotor assembly 120 and the second rotor assembly 220 are also the same. Similarly, by setting the first rotor assembly 120 and the second rotor assembly 220 to have the same structure, there is no need to distinguish between the first rotor assembly 120 and the second rotor assembly 220 during assembly, which improves the error tolerance rate during the assembly process of the motor 10, improves the assembly efficiency, and thus improves the production efficiency; moreover, the first rotor assembly 120 and the second rotor assembly 220 have the same rotor core, and the rotor cores of the two can be processed and completed in the same processing procedure, further improving the production efficiency.

[0091] It can be understood that after the first end cover 140 and the second end cover 240 are positioned and fitted, the first end cover 140 and the second end cover 240 can be connected by screws or rivets to connect the first motor 100 and the second motor 200 into one body.

[0092] To enhance the firmness of the connection between the first motor 100 and the second motor 200, in one embodiment, the first stator assembly 110 is provided with a first connection hole (not shown) penetrating axially therethrough, the second stator assembly 210 is provided with a second connection hole (not shown) penetrating axially therethrough, the first end cover 140 is provided with a first through hole 140a, and the second end cover 240 is provided with a second through hole 240a. When the first end cover 140 and the second end cover 240 are positioned and fitted, the first through hole 140a and the second through hole 240a are coaxially arranged. The first stator assembly 110 is connected to the second stator assembly 210 by a fastener passing through the first connection hole, the first through hole 140a, the second through hole 240a, and the second connection hole, which can ensure that the first motor 100 and the second motor 200 are firmly connected together. Among them, the fastener can be a screw, a rivet, etc.

[0093] Please refer to Figure 1 、 Figure 2 and Figure 8 and Figure 9 , Figure 8 FIG. Figure 9 is an assembly schematic diagram of the first drive shaft and the first rotor assembly according to an embodiment of the present invention,

[0094] FIG.

[0095] Figure 9 is an assembly schematic diagram of the second drive shaft and the second rotor assembly according to an embodiment of the present invention. The motor 10 includes a first bearing 150, a second bearing 160, a third bearing 250, and a fourth bearing 260. Among them, the first bearing 150 and the second bearing 160 are respectively arranged on both axial sides of the first rotor assembly 120, and the first bearing 150 and the second bearing 160 are rotationally engaged with the first drive shaft 130. The third bearing 250 and the fourth bearing 260 are respectively arranged on both axial sides of the second rotor assembly 220 (i.e., the second stator assembly 210), and the third bearing 250 and the fourth bearing 260 are rotationally engaged with the second drive shaft 230. Among them, the first bearing 150 is located on the side of the first rotor assembly 120 close to the second motor 200, and the third bearing 250 is located on the side of the second rotor assembly 220 close to the first motor 100.

[0094] To support and fix the first bearing 150 and the second bearing 160, in one embodiment, the first bearing 150 is supported by the first end cover 140, and the third bearing 250 is supported by the second end cover 240. Then, both the first end cover 140 and the second end cover 240 have two functions, not only for connection but also for support. In this embodiment, by supporting the first bearing 150 with the first end cover 140, other support structures on one axial side of the first end cover 140 are omitted. By supporting the third bearing 250 with the second end cover 240, other support structures on one axial side of the second end cover 240 are omitted, reducing the axial length of the motor 10, which can reduce the overall volume of the motor 10 and further reduce the occupation of the internal space of the dryer.

[0095] Please refer to Figure 1 , Figure 3 and Figure 5 The first end cover 140 includes a first support member 143, which is disposed on the first cover body 141. The first support member 143 is provided with a first mounting groove 1431, and the first bearing 150 is mounted in the first mounting groove 1431. The first support member 143 indirectly supports the first drive shaft 130 by supporting the first bearing 150. The outer ring of the first bearing 150 is interference-connected with the groove wall of the first mounting groove 1431, and the inner ring of the first bearing 150 is fixedly connected with the first drive shaft 130.

[0096] The first support member 143 is a metal member, so that the first support member 143 has sufficient strength to better withstand the load acting on the first support member 143 when the first drive shaft 130 rotates, reduce deformation, and improve the reliability of the rotation of the first drive shaft 130. Figure 1 As shown, the first support member 143 is designed to be sleeve-shaped, and the first support member 143 can be formed by stamping a metal plate.

[0097] In one embodiment, the first support member 143 and the first cover body 141 are integrally formed by overmolding. Specifically, the entire first cover body 141 is an injection molded body. During the injection molding process, the processed first support member 143 is first positioned in the injection mold, and then the injection mold is filled with injection liquid. After the injection liquid solidifies and forms, the above-mentioned first cover body 141 is formed, and the first support member 143 and the first cover body 141 are connected as a whole. This embodiment uses an overmolding process to consolidate the first support member 143 and the first cover body 141 into one. During the assembly process of the first motor 100, the installation steps of the first support member 143 and the first cover body 141 are omitted, which can further improve production efficiency.

[0098] Of course, in other optional embodiments of the present application, the first cover body 141 and the first support member 143 may also be connected separately. For example, the first support member 143 may be connected to the first cover body 141 by interference fit, screw connection, etc.

[0099] Please refer to Figure 1 , Figure 4 and Figure 6 The second end cover 240 includes a second support member 243, and the second support member 243 is disposed on the second cover body 241. The second support member 243 is provided with a second mounting groove 2431, and the third bearing 250 is mounted in the second mounting groove 2431. The second support member 243 indirectly supports the second drive shaft 230 by supporting the third bearing 250. The outer ring of the third bearing 250 is interference-connected with the groove wall of the second mounting groove 2431, and the inner ring of the third bearing 250 is fixedly connected with the second drive shaft 230.

[0100] Similarly, the second support member 243 is also configured as a metal member, so that the second support member 243 has sufficient strength to better withstand the load acting on the second support member 243 when the second drive shaft 230 rotates, reduce deformation, and improve the reliability of the rotation of the second drive shaft 230. Figure 1 As shown, the second support member 243 is designed to be sleeve-shaped, and the second support member 243 can be formed by stamping a metal plate.

[0101] In one embodiment, the second support member 243 is integrally molded with the second cover body 241. It is understandable that the process of connecting the second support member 243 to the second cover body 241 using the molding process is the same as that of the first support member 143, and the present application will not repeat it in detail here. By molding the second support member 243 and the second cover body 241 as a whole, the installation steps of the second support member 243 and the second cover body 241 are omitted, which effectively improves the assembly efficiency and can improve the production efficiency.

[0102] Please combine Figure 1 And refer to Figure 10 , Figure 10 The first stator assembly 110 includes a first stator core 112, a third support member 113, and a first plastic-encapsulated housing 111 covering the first stator core 112 and the third support member 113, that is, the first stator core 112 and the third support member 113 are integrally fixed by plastic-encapsulation.

[0103] The third support member 113 is used to support the second bearing 160. The third support member 113 is provided with a third mounting groove (not shown), and the second bearing 160 is mounted in the third mounting groove. By integrating the third support member 113 on the first stator assembly 110 by using a plastic coating process, the installation step of the third support member 113 is omitted, and production efficiency can be improved.

[0104] Please combine Figure 1 And refer to Figure 11 , Figure 11 The second stator assembly 210 includes a second stator core 212, a fourth support member 213, and a second plastic-encapsulated housing 211 covering the second stator core 212 and the fourth support member 213, that is, the second stator core 212 and the fourth support member 213 are integrally fixed by plastic-encapsulation.

[0105] Among them, the fourth support member 213 is used to support the fourth bearing 260. The fourth support member 213 is provided with a fourth installation groove (not labeled), and the fourth bearing 260 is installed in the fourth installation groove. Similarly, by integrating the fourth support member 213 on the second stator assembly 210 using the plastic coating process, the installation steps of the fourth support member 213 are omitted, and the production efficiency can be improved.

[0106] To ensure the coaxiality of the first bearing 150 and the second bearing 160, in one embodiment, please refer to Figure 1 、 Figure 3 and Figure 10 , the first plastic-sealed housing 111 is provided with a first receiving groove 1111. The groove wall of the first receiving groove 1111 forms a first positioning surface 1112. The first end cover 140 is provided with a first plugging portion 1411. The first plugging portion 1411 is plugged into the first receiving groove 1111 and is in positioning cooperation with the first positioning surface 1112.

[0107] Among them, the first positioning surface 1112 can be designed as a cylindrical mating surface. Correspondingly, the first plugging portion 1411 is designed to be cylindrical. When the first end cover 140 is connected to the first stator assembly 110, positioning is performed through the above-mentioned first positioning surface 1112 and the first plugging portion 1411 to ensure the coaxial mating of the first stator assembly 110 and the first end cover 140, ensure the coaxiality of the first support member 143 and the third support member 113, and thus ensure the coaxiality of the first bearing 150 and the second bearing 160, so that the first drive shaft 130 rotates smoothly and reliably.

[0108] Correspondingly, to ensure the coaxiality of the third bearing 250 and the fourth bearing 260, please refer to Figure 1 、 Figure 4 and Figure 11 , the second plastic-sealed housing 211 is provided with a second receiving groove 2111. The groove wall of the second receiving groove 2111 forms a second positioning surface 2112. The second end cover 240 is provided with a second plugging portion 2411. The second plugging portion 2411 is plugged into the second receiving groove 2111 and is in positioning cooperation with the second positioning surface 2112.

[0109] Among them, the second positioning surface 2112 can also be designed as a cylindrical mating surface. Correspondingly, the second plugging portion 2411 is designed to be cylindrical. When the second end cover 240 is connected to the second stator assembly 210, positioning is performed through the above-mentioned second positioning surface 2112 and the second plugging portion 2411 to ensure the coaxial mating of the second stator assembly 210 and the second end cover 240, ensure the coaxiality of the second support member 243 and the fourth support member 213, and thus ensure the coaxiality of the third bearing 250 and the fourth bearing 260, so that the second drive shaft 230 rotates smoothly and reliably.

[0110] In one embodiment, the first insertion portion 1411 and the first positioning surface 1112 are in interference fit, that is, they are tightly fitted, so that the first end cover 140 is firmly connected to the first stator assembly 110, preventing the two from loosening under the action of vibration during transportation. Before the first motor 100 and the second motor 200 are assembled, there is no need to use screws or other fasteners to ensure the integrity of the first motor 100. Thus, when the two are assembled, the first motor 100 and the second motor 200 can be directly assembled, improving the assembly efficiency and further improving the production efficiency.

[0111] In one embodiment, the second insertion portion 2411 and the second positioning surface 2112 are in interference fit, enhancing the firmness of the connection between the second end cover 240 and the second stator assembly 210, preventing the two from becoming loose under the action of vibration during transportation. Before the second motor 200 and the first motor 100 are assembled, there is no need to use screws or other fasteners to ensure the integrity of the second motor 200. Thus, when the two are assembled, they can be directly assembled, improving the assembly efficiency and further improving the production efficiency.

[0112] In one embodiment, the motor 10 further includes a belt drive assembly 300, and the second motor 200 drives the drum to rotate through the belt drive assembly 300. Specifically, the belt drive assembly 300 includes a first pulley 310, a second pulley 320, and a belt 330 wound around the first pulley 310 and the second pulley 320.

The support arm 214 is connected to the second plastic enclosure 211. A connecting shaft 215 is provided at one end of the support arm 214 away from the second plastic enclosure 211. The first pulley 310 is rotatably mounted on the connecting shaft 215 and is connected to the drum. The second pulley 320 is fixedly connected to the second drive shaft 230. Thus, when the second motor 200 operates, the second drive shaft 230 drives the second pulley 320 to rotate, the second pulley 320 drives the belt 330 to transmit power, and the belt 330 drives the first pulley 310 to rotate, thereby driving the drum to rotate.

[0113] In one embodiment, the second plastic enclosure 211 and the support arm 214 are integrally formed by overmolding. In this embodiment, the support arm 214 and the second plastic enclosure 211 are consolidated into an integral structure by overmolding, making the support arm 214 a part of the second stator assembly 210.
