[0035] To better understand the above-mentioned objectives, features, and advantages of this application, the application 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.
[0036] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0037] The stator assembly 100, motor 300, and garment handling apparatus according to some embodiments of this application will now be described with reference to Figures 1 to 7.
[0038] In one embodiment of this application, as shown in Figures 1, 2, 3, 4, 5, 6, and 7, a stator assembly 100 is provided. The stator assembly 100 includes: a stator component 110; and a package 120, the package 120 including a package body 121, a support boss 122, and a first mounting post 123. The stator component 110 is packaged inside the package body 121, and the support boss 122 and the first mounting post 123 are located outside the package body 121. The 3 and the encapsulation body 121 enclose each other to form a positioning groove 130. The first mounting post 123 includes a first mating surface 124, which constitutes part of the groove wall of the positioning groove 130. The mounting bracket 140 includes a connected positioning part 141 and a second mounting post 142. The second mounting post 142 is connected to the first mounting post 123. At least a part of the positioning part 141 is inserted into the positioning groove 130. The positioning part 141 includes a second mating surface 143, which mates with the first mating surface 124.
[0039] The stator assembly 100 provided in this embodiment includes a stator component 110, a package 120, and a mounting bracket 140. Specifically, the package 120 includes a package body 121, a support boss 122, and a first mounting post 123. The stator component 110 is encapsulated inside the package body 121, that is, the stator component 110 and the package 120 are integrally molded. Exemplarily, the support boss 122 extends circumferentially and radially inwardly along the stator component 110. By providing the support boss 122, the stator assembly 100 can be supported, improving the structural strength of the stator assembly 100.
[0040] The encapsulation body 121, the support boss 122, and the first mounting post 123 enclose and form a positioning groove 130. At least a portion of the positioning part 141 is inserted into the positioning groove 130. At the same time, the first mating surface 124 of the first mounting post 123 and the second mating surface 143 of the positioning part 141 cooperate to achieve precise positioning of the mounting frame 140, ensuring the relative position between the mounting frame 140 and the garment processing device. This is beneficial to improving the installation efficiency of the stator assembly 100 and the installation structure between the stator assembly 100 and the garment processing device, shortening the installation time, and thus helping to reduce the production cost of the garment processing device.
[0041] Understandably, the mounting bracket 140 is used to connect with the mounting structure of the garment handling device. In other words, compared with the mounting feet formed by BMC material and connected to the washing machine in related technologies, a separate mounting bracket 140 and encapsulation component 120 are used. The mounting bracket 140 is used to ensure the strength and reliability of the connection between the motor 300 and the garment handling device. That is, the encapsulation structure of the stator assembly 110 and the encapsulation component 120, which are integrally molded, and the mounting bracket 140 are manufactured separately. Under the premise of ensuring that the overall encapsulation structure of the stator assembly 110 remains unchanged, the mounting bracket 140 is used to realize the assembly between the stator assembly 100 and the garment handling device, avoiding the breakage of the connection between the motor 300 and the garment handling device due to insufficient strength, and improving the reliability of the garment handling device.
[0042] Meanwhile, since the overall packaging structure of the stator assembly 110 remains unchanged, the mounting structure of different types of clothing processing devices can be matched by changing the mounting characteristics of the mounting bracket 140 and the clothing processing device. This is conducive to the standardization of the motor 300 and reduces the number of molds for the overall packaging structure of the stator assembly 110, making production easier and reducing the production cost of the motor 300 and the clothing processing device.
[0043] In addition, the second mounting post 142 is connected to the first mounting post 123, thereby realizing the fixed assembly between the mounting bracket 140 and the package 120.
[0044] For example, the stator assembly 100 also includes a rear mounting foot, which is distributed along the axial direction of the stator assembly 110 with the mounting bracket 140. That is, the mounting bracket 140 is a front support. It is understood that the front support position will be subjected to force during the operation of the garment handling device. Therefore, the separate mounting bracket 140 and the encapsulation 120 are used at the position of the front support, which is beneficial to further improve the reliability of the garment handling device.
[0045] For example, the stator assembly 100 also includes an end cap disposed at one end of the package body 121 away from the mounting bracket 140.
[0046] For example, the mating of the first mating surface 124 and the second mating surface 143 specifically includes either a contact mating or a clearance mating. The specific configuration can be adjusted according to actual needs.
[0047] For example, the stator assembly 110 includes a stator core, a frame, and windings, and the encapsulation body 121 encapsulates the stator core, frame, and windings together to form an encapsulation structure.
[0048] For example, there are two mounting brackets 140 and two first mounting posts 123. The two first mounting posts 123 are respectively enclosed with the support boss 122 and the encapsulation body 121 to form two positioning grooves 130. The positioning parts 141 of the two mounting brackets 140 are respectively inserted into the two positioning grooves 130.
[0049] As shown in Figures 1 and 2, in some embodiments, exemplary, the second mating surface 143 mates with the first mating surface 124 along the radial direction of the stator assembly 110.
[0050] In this embodiment, the second mating surface 143 is defined to mate with the first mating surface 124 along the radial direction of the stator assembly 110, thereby positioning the mounting bracket 140 in the radial direction, which helps to improve the connection strength and installation stability between the mounting bracket 140 and the package 120.
[0051] As shown in Figures 3 and 4, in some embodiments, exemplarily, at least a portion of the first mating surface 124 is configured as a first arcuate surface 125; at least a portion of the second mating surface 143 is configured as a second arcuate surface 144, the shape of the second arcuate surface 144 being adapted to the shape of the first arcuate surface 125.
[0052] In this embodiment, at least a portion of the first mating surface 124 is defined as a first arc-shaped surface 125. Specifically, at least a portion of the second mating surface 143 is a second arc-shaped surface 144, and the shape of the second arc-shaped surface 144 is adapted to the shape of the first arc-shaped surface 125. Since the first mating surface 124 and the second mating surface 143 mate, that is, the first arc-shaped surface 125 and the second arc-shaped surface 144 mate, thereby enabling precise positioning of the mounting bracket 140 while increasing the contact area between the positioning part 141 and the first mounting post 123. This ensures the uniformity of force between the first mounting post 123 and the positioning part 141, which is beneficial to improving the installation stability and reliability between the mounting bracket 140 and the package 120.
[0053] Furthermore, setting at least a portion of the first mating surface 124 as a first arc-shaped surface 125, and setting at least a portion of the second mating surface 143 as a second arc-shaped surface 144, helps to reduce processing difficulty and facilitates installation, thereby reducing production costs.
[0054] In some embodiments, for example, the diameter of the first arcuate surface 125 is smaller than the diameter of the second arcuate surface 144.
[0055] In this embodiment, the diameter of the first arc-shaped surface 125 is limited to be smaller than the diameter of the second arc-shaped surface 144. On the one hand, this facilitates the smooth insertion of the positioning part 141 into the positioning groove 130, which is beneficial to improving the assembly efficiency between the mounting bracket 140 and the package 120. On the other hand, when the positioning part 141 is inserted into the positioning groove 130, there is a certain gap between the first arc-shaped surface 125 and the second arc-shaped surface 144, that is, the first arc-shaped surface 125 and the second arc-shaped surface 144 are in clearance fit. This reduces the risk of breakage when the garment processing device is subjected to force during operation, thereby improving the reliability of the garment processing device.
[0056] As shown in Figures 1, 2, 3 and 4, in some embodiments, for example, the support boss 122 includes a third mating surface 126, which forms part of the groove wall of the positioning groove 130, and the third mating surface 126 is opposite to the first mating surface 124; the positioning part 141 also includes a fourth mating surface 145, which mates with the third mating surface 126.
[0057] In this embodiment, the support boss 122 includes a third mating surface 126. Specifically, the third mating surface 126 is opposite to the first mating surface 124, that is, the third mating surface 126 and the first mating surface 124 are two opposing groove walls within the positioning groove 130. Exemplarily, the third mating surface 126 is opposite to the first mating surface 124 along the radial direction of the stator assembly 110.
[0058] The positioning part 141 also includes a fourth mating surface 145, which mates with the third mating surface 126. That is, when the positioning part 141 is inserted into the positioning groove 130, in addition to the second mating surface 143 on the side of the positioning part 141 away from the central axis of the stator assembly 110 mates with the first mating surface 124 of the first mounting post 123, the fourth mating surface 145 on the side of the positioning part 141 near the central axis of the stator assembly 110 mates with the third mating surface 126 of the support boss 122. This can further improve the positioning accuracy of the mounting bracket 140, achieve complete positioning of the mounting bracket 140 on the encapsulation 120, improve the connection effect between the mounting bracket 140 and the encapsulation 120, and thus ensure the relative position between the mounting bracket 140 and the garment processing device. This is beneficial to improving the installation efficiency of the stator assembly 100 and the installation structure between the stator assembly 100 and the garment processing device.
[0059] Furthermore, since the inner and outer mating surfaces of the positioning part 141 respectively mate with the first mounting post 123 and the support boss 122, it helps to improve the overall structural strength of the mounting frame 140, reduce the risk of the mounting frame 140 breaking, and improve the reliability of the clothing processing device.
[0060] For example, the mating of the third mating surface 126 and the fourth mating surface 145 specifically includes a contact mating of the third mating surface 126 and the fourth mating surface 145, or a clearance mating of the third mating surface 126 and the fourth mating surface 145. The specific configuration can be adjusted according to actual needs.
[0061] As shown in Figures 3 and 4, in some embodiments, exemplarily, at least a portion of the third mating surface 126 is configured as a third arcuate surface 127, the center of the third arcuate surface 127 coincides with the center of the first arcuate surface 125, and the diameter of the third arcuate surface 127 is larger than the diameter of the first arcuate surface 125; at least a portion of the fourth mating surface 145 is configured as a fourth arcuate surface 146, and the shape of the fourth arcuate surface 146 is adapted to the shape of the third arcuate surface 127.
[0062] In this embodiment, at least a portion of the third mating surface 126 is defined as a third arc-shaped surface 127. Specifically, the center of the third arc-shaped surface 127 coincides with the center of the first arc-shaped surface 125, meaning that the third arc-shaped surface 127 and the first arc-shaped surface 125 are concentric arc surfaces. The diameter of the third arc-shaped surface 127 is larger than the diameter of the first arc-shaped surface 125, meaning that the first mounting post 123 and the support boss 122 are spaced apart, thereby forming a positioning groove 130 together with the encapsulation body 121.
[0063] At least a portion of the fourth mating surface 145 is a fourth arc-shaped surface 146, and the shape of the fourth arc-shaped surface 146 is adapted to the shape of the third arc-shaped surface 127. Since the shape of the second arc-shaped surface 144 is adapted to the shape of the first arc-shaped surface 125, that is, the second arc-shaped surface 144 and the fourth arc-shaped surface 146 are concentric circular arc surfaces, and the diameter of the fourth arc-shaped surface 146 is larger than the diameter of the second arc-shaped surface 144.
[0064] Since the third mating surface 126 and the fourth mating surface 145 are mated, that is, the third arc-shaped surface 127 and the fourth arc-shaped surface 146 are mated, the contact area between the positioning part 141 and the support boss 122 can be increased while achieving precise positioning of the mounting bracket 140. This ensures the uniformity of force between the support boss 122 and the positioning part 141, which is beneficial to improving the installation stability and reliability between the mounting bracket 140 and the package 120.
[0065] Furthermore, setting at least a portion of the third mating surface 126 as the third arc-shaped surface 127, and setting at least a portion of the fourth mating surface 145 as the fourth arc-shaped surface 146, helps to reduce processing difficulty and facilitates installation, thereby reducing production costs.
[0066] In some embodiments, for example, the diameter of the third arcuate surface 127 is greater than the diameter of the fourth arcuate surface 146.
[0067] In this embodiment, the diameter of the third arc-shaped surface 127 is defined to be larger than the diameter of the fourth arc-shaped surface 146. On the one hand, this facilitates the smooth insertion of the positioning part 141 into the positioning groove 130, which is beneficial to improving the assembly efficiency between the mounting bracket 140 and the package 120. On the other hand, when the positioning part 141 is inserted into the positioning groove 130, there is a certain gap between the third arc-shaped surface 127 and the fourth arc-shaped surface 146, that is, the third arc-shaped surface 127 and the fourth arc-shaped surface 146 are in clearance fit. Therefore, when the garment processing device is subjected to force during operation, the risk of breakage can be reduced, and the reliability of the garment processing device can be improved.
[0068] As shown in Figures 1 and 2, in some embodiments, exemplarily, the side of the first mounting post 123 facing the second mounting post 142 is in contact with the side of the second mounting post 142 facing the first mounting post 123.
[0069] In this embodiment, the side of the first mounting post 123 facing the second mounting post 142 is defined to be in contact with the side of the second mounting post 142 facing the first mounting post 123. For example, the side of the first mounting post 123 facing the second mounting post 142 is provided with a first plane, and the side of the second mounting post 142 facing the first mounting post 123 is provided with a second plane. The second plane is in contact with the first plane, thereby enabling the mounting bracket 140 to be positioned axially in the stator assembly 110, improving the connection strength between the mounting bracket 140 and the encapsulation 120, further ensuring the relative position between the mounting bracket 140 and the garment processing device, which is beneficial to improving the installation efficiency of the stator assembly 100 and the installation between the stator assembly 100 and the garment processing device, shortening the installation time, and thus helping to reduce the production cost of the garment processing device.
[0070] As shown in Figures 3 and 6, in some embodiments, the mounting bracket 140, exemplarily, further includes a mounting portion 147 and a reinforcing plate 148, wherein the mounting portion 147 is located on the side of the second mounting post 142 away from the positioning portion 141 and is connected to the second mounting post 142, and the two ends of the reinforcing plate 148 are respectively connected to the mounting portion 147 and the positioning portion 141.
[0071] In this embodiment, the mounting bracket 140 is further defined as including a mounting part 147 and a reinforcing plate 148. Specifically, it can be understood that the mounting part 147 is used to connect the mounting structure of the clothes handling device. That is, compared with the mounting feet formed by BMC material and connected to the washing machine in related technologies, a separate mounting bracket 140 and encapsulation 120 are used. The mounting bracket 140 is used to ensure the strength and reliability of the connection between the motor 300 and the clothes handling device. That is, the encapsulation structure of the stator assembly 110 and the encapsulation 120, which are integrally molded, and the mounting bracket 140 are manufactured separately. Under the premise of ensuring that the overall encapsulation structure of the stator assembly 110 remains unchanged, the mounting bracket 140 is used to realize the assembly between the stator assembly 100 and the clothes handling device, avoiding the breakage of the connection between the motor 300 and the clothes handling device due to insufficient strength, and improving the reliability of the clothes handling device.
[0072] The mounting portion 147 is located on the side of the second mounting post 142 away from the positioning portion 141, meaning that the second mounting post 142 is located between the positioning portion 141 and the mounting portion 147. One end of the reinforcing plate 148 is connected to the mounting portion 147, and the other end of the reinforcing plate 148 is connected to the positioning portion 141. This helps to improve the overall structural strength of the mounting frame 140, reduces the risk of breakage of the mounting frame 140 when subjected to installation forces and forces caused by vibrations from the garment processing device, and further improves the reliability of the garment processing device.
[0073] For example, the second mounting post 142, the mounting part 147 and the positioning part 141 are an integral structure.
[0074] As shown in FIG6, in some embodiments, the mounting bracket 140, exemplary, further includes a reinforcing rib 149, which is disposed on the side of the mounting portion 147 facing the second mounting post 142.
[0075] In this embodiment, the mounting bracket 140 further includes reinforcing ribs 149. Specifically, the reinforcing ribs 149 are disposed on the side of the mounting portion 147 facing the second mounting post 142, thereby improving the structural strength of the mounting portion 147. Since the mounting portion 147 is used to connect the mounting structure of the garment handling device, improving the structural strength of the mounting portion 147 can reduce the risk of breakage and improve the reliability of the garment handling device.
[0076] For example, the number of reinforcing ribs 149 is multiple.
[0077] For example, the reinforcing rib 149 is connected to the second mounting post 142, which helps to further improve the overall structural strength of the mounting bracket 140.
[0078] As shown in Figures 1, 2, 5, and 6, in some embodiments, for example, the first mounting post 123 is provided with a first connecting hole 150, the second mounting post 142 is provided with a second connecting hole 160, and the mounting bracket 140 further includes a mounting ring 170, which is located on the side of the second mounting post 142 away from the first mounting post 123 and communicates with the second connecting hole 160; the stator assembly 100 further includes a fastener 180, which passes through the second connecting hole 160 and the first connecting hole 150 respectively, so that the second mounting post 142 and the first mounting post 123 are connected, and a portion of the fastener 180 is located inside the mounting ring 170.
[0079] In this embodiment, the stator assembly 100 is further defined as including a fastener 180. Specifically, the first mounting post 123 is provided with a first connecting hole 150, and the second mounting post 142 is provided with a second connecting hole 160. The fastener 180 passes through the second connecting hole 160 and the first connecting hole 150 respectively, thereby realizing the fixed assembly between the first mounting post 123 and the second mounting post 142.
[0080] Since some of the fasteners 180 are located within the mounting ring 170, these fasteners 180 can be positioned and fixed, which helps to improve the fixing effect between the mounting bracket 140 and the package 120 and improves the reliability of the garment processing device.
[0081] For example, the fastener 180 includes a bolt and a nut, the bolt passing through the second connecting hole 160 and the first connecting hole 150 respectively, and the nut being disposed on the bolt and located within the mounting ring 170 for positioning and fixing the nut.
[0082] For example, the portion of the mounting bracket 140 opposite to the second mounting post 142 protrudes outward to form a ring, namely the mounting ring 170.
[0083] As shown in Figures 1 and 2, in some embodiments, exemplary, a gap 190 is provided between the positioning portion 141 and the bottom wall of the positioning groove 130 along the axial direction of the stator assembly 110.
[0084] In this embodiment, when the positioning part 141 is inserted into the positioning groove 130, there is an axial gap 190 between the positioning part 141 and the bottom wall of the positioning groove 130 to avoid over-positioning in the axial direction and to ensure the installation effect between the mounting bracket 140 and the package 120.
[0085] As shown in Figures 3 and 6, in some embodiments, for example, there are two mounting brackets 140, and at least one mounting bracket 140 has a positioning part 141 inserted into a positioning groove 130. The stator assembly 100 also includes a connecting plate 210 and a reinforcing rib 220, wherein the two ends of the connecting plate 210 are respectively connected to the two mounting brackets 140, and the reinforcing rib 220 is provided on the connecting plate 210.
[0086] In this embodiment, the stator assembly 100 is further defined as including a connecting plate 210 and a reinforcing rib 220. Specifically, there are two mounting brackets 140, and the positioning part 141 of at least one mounting bracket 140 is inserted into the positioning groove 130. For example, there are also two first mounting posts 123. The two first mounting posts 123 are respectively enclosed with the support boss 122 and the encapsulation body 121 to form two positioning grooves 130, and the positioning parts 141 of the two mounting brackets 140 are respectively inserted into the two positioning grooves 130.
[0087] One end of the connecting plate 210 is connected to one of the mounting brackets 140, and the other end of the connecting plate 210 is connected to another mounting bracket 140, so that the two mounting brackets 140 and the connecting plate 210 form a whole.
[0088] The reinforcing rib 220 is provided on the connecting plate 210, thereby improving the structural strength of the connecting plate 210, and further improving the overall structural strength of the two mounting brackets 140 and the connecting plate 210, ensuring the assembly effect between the stator assembly 100 and the mounting structure of the garment processing device, and improving the reliability of the garment processing device.
[0089] For example, the number of reinforcing ribs 220 is multiple.
[0090] In some embodiments, for example, the mounting bracket 140 includes an aluminum alloy bracket or a plastic bracket; and / or the package 120 includes a bulk molding compound.
[0091] In this embodiment, the mounting bracket 140 is defined as an aluminum alloy bracket or a plastic bracket. That is, compared with the mounting feet formed by BMC material and connected to the washing machine in related technologies, a separate aluminum alloy bracket and encapsulation component 120, or a separate plastic bracket and encapsulation component 120, are used. The aluminum alloy bracket or plastic bracket is used to ensure the strength and reliability of the connection between the motor 300 and the clothes handling device. That is, the encapsulation structure of the stator assembly 110 and the encapsulation component 120, which are integrally molded, and the aluminum alloy bracket or plastic bracket are manufactured separately. Under the premise of ensuring that the overall encapsulation structure of the stator assembly 110 remains unchanged, the aluminum alloy bracket or plastic bracket is used to realize the assembly between the stator assembly 100 and the clothes handling device, avoiding the breakage of the connection between the motor 300 and the clothes handling device due to insufficient strength, and improving the reliability of the clothes handling device.
[0092] The plastic frame is made of high-strength plastic components.
[0093] The encapsulation component 120 includes a bulk molding compound, that is, the stator assembly 110 is encapsulated using BMC material, which helps to reduce the production cost of the motor 300 and the garment processing device.
[0094] According to a second aspect of this application, an electric motor 300 is provided, including a stator assembly 100 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the stator assembly 100, which will not be repeated here.
[0095] Exemplarily, the motor 300 also includes a rotor disposed on the stator assembly 100. In some embodiments, the stator assembly 100 includes a stator component 110, a package 120, and a mounting bracket 140. Specifically, the package 120 includes a package body 121, a support boss 122, and a first mounting post 123. The stator component 110 is encapsulated inside the package body 121, that is, the stator component 110 and the package 120 are integrally molded. Exemplarily, the support boss 122 extends circumferentially and radially inwardly along the stator component 110. By providing the support boss 122, the stator assembly 100 can be supported, thereby improving the structural strength of the stator assembly 100.
[0096] The encapsulation body 121, the support boss 122, and the first mounting post 123 enclose and form a positioning groove 130. At least a portion of the positioning part 141 is inserted into the positioning groove 130. At the same time, the first mating surface 124 of the first mounting post 123 and the second mating surface 143 of the positioning part 141 cooperate to achieve precise positioning of the mounting frame 140, ensuring the relative position between the mounting frame 140 and the garment processing device. This is beneficial to improving the installation efficiency of the stator assembly 100 and the installation structure between the stator assembly 100 and the garment processing device, shortening the installation time, and thus helping to reduce the production cost of the garment processing device.
[0097] Understandably, the mounting bracket 140 is used to connect with the mounting structure of the garment handling device. In other words, compared with the mounting feet formed by BMC material and connected to the washing machine in related technologies, a separate mounting bracket 140 and encapsulation component 120 are used. The mounting bracket 140 is used to ensure the strength and reliability of the connection between the motor 300 and the garment handling device. That is, the encapsulation structure of the stator assembly 110 and the encapsulation component 120, which are integrally molded, and the mounting bracket 140 are manufactured separately. Under the premise of ensuring that the overall encapsulation structure of the stator assembly 110 remains unchanged, the mounting bracket 140 is used to realize the assembly between the stator assembly 100 and the garment handling device, avoiding the breakage of the connection between the motor 300 and the garment handling device due to insufficient strength, and improving the reliability of the garment handling device.
[0098] Meanwhile, since the overall packaging structure of the stator assembly 110 remains unchanged, the mounting structure of different types of clothing processing devices can be matched by changing the mounting characteristics of the mounting bracket 140 and the clothing processing device. This is conducive to the standardization of the motor 300 and reduces the number of molds for the overall packaging structure of the stator assembly 110, making production easier and reducing the production cost of the motor 300 and the clothing processing device.
[0099] According to a third aspect of this application, a garment handling apparatus is provided, including a stator assembly 100 or a motor 300 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the stator assembly 100 or the motor 300, which will not be repeated here.
