[0047] Embodiments of the first aspect

[0048] An embodiment of the first aspect of the present application provides a motor end cover. Figure 1 It is a schematic diagram of the motor end cover 10 of the embodiment of the first aspect of the present application. Figure 2 yes Figure 1 A schematic diagram of a sub-component of the motor end cover 10 is shown, Figure 3 yes Figure 1A schematic diagram of another subassembly of the motor end cover 10 is shown. Figure 4 yes Figure 1 Another schematic diagram of the motor end cover 10 is shown, showing the Figure 1 Observation from different angles.

[0049] In the embodiment of the present application, the motor end cover includes at least two sub-components assembled in a detachable manner, for example, Figures 1 to 4 The motor end cover 10 is shown to include Figure 2 The subassembly 11 and Figure 3 The two sub-components of the sub-component 12 shown, sub-component 11 and sub-component 12 can be assembled in a detachable manner, but the present application is not limited to this. Sub-component 11 and sub-component 12 can be assembled in a non-detachable manner. In addition, the motor end cover can also include 3 sub-components or more than 3 sub-components assembled with each other, and the present application does not impose any restrictions on this.

[0050] In the embodiment of the present application, at least one sub-component of the motor end cover 10 is provided with a leg for fixing the at least one sub-component to the motor. Figures 1 to 4 As shown, the sub-component 11 is provided with a support leg 13 for fixing the sub-component 11 to the motor, and the sub-component 12 is also provided with a support leg 14 for fixing the sub-component 12 to the motor, but the present application is not limited thereto. For example, the support leg 13 may be provided only on the sub-component 11, or the support leg 14 may be provided only on the sub-component 12. In addition, when the motor end cover 10 includes at least 3 sub-components, at least one of the at least 3 sub-components may be provided with a support leg, which will not be exemplified one by one here.

[0051] In the embodiment of the present application, fixing the sub-component to the motor means that the support leg can be fixed to other components of the motor, and the other components can be the stator core of the motor, but the present application is not limited to this. For example, the motor can be provided with a motor end cover at each axial end, and the support leg can be fixed to the motor end cover on the other axial side of the motor.

[0052] In one or more embodiments, at least one leg is provided with a fixing assembly portion for fixing the sub-component to the motor, thereby enabling the motor and other components to be fixed to each other.

[0053] For example, Figure 1 and Figure 4 As shown, the fixing assembly portion 22 may include through holes provided on the legs 13 and 14, whereby the sub-components 11 and 12 and other components of the motor may be fixed to each other by passing bolts or other components through the through holes. Figure 1 and Figure 4 As shown, the through hole of the fixed assembly portion 22 can penetrate the legs 13 and 14 in the radial direction, but the present application is not limited thereto. For example, Figure 5 and Figure 6 Another schematic diagram of the motor end cover of the embodiment of the present application is shown, as Figure 5 and Figure 6 As shown, the fixing assembly portion can be a plate-shaped portion 30 provided at the ends of the legs 13 and 14 and perpendicular to the axial direction, and the fixing assembly portion 22 can include a through hole that axially passes through the plate-shaped portion 30. In this way, the sub-components 11 and 23 and other components of the motor can be fixed to each other.

[0054] However, the present application is not limited thereto, and the fixed assembly portion 22 may be other structures, such as a snap-fit ​​structure and an adhesive structure.

[0055] In the embodiment of the present application, the fixed assembly portion 22 can be provided on at least one leg, for example Figure 4 It is shown that the fixed assembly parts 22 are provided on all, for example, four legs, but the present application is not limited thereto. The fixed assembly parts 22 can be provided on only any one, two or three of the four legs according to actual needs.

[0056] In the embodiment of the present application, there is no limitation on the number of legs. For example, Figures 1 to 4 It is shown that the sub-component 11 and the sub-component 12 are respectively provided with two legs, that is, the motor end cover 10 includes 4 legs, but the present application is not limited thereto. For example, the motor end cover 10 may also include 2 legs, and the 2 legs may be provided on the sub-component 11 or the sub-component 12 or one is provided on each of the sub-component 11 and the sub-component 12, and the 2 legs may be circumferentially opposite to each other. For another example, the motor end cover 10 may also include 3 legs, and the 3 legs may all be provided on the sub-component 11 or the sub-component 12 or at least one is provided on each of the sub-component 11 and the sub-component 12, and the 3 legs may be circumferentially equally spaced. In addition, the number of legs may also be 5 or more than 5, which can be set according to actual needs.

[0057] It can be seen from the above embodiments that the motor end cover includes at least two sub-components assembled in a detachable manner. Therefore, without affecting the performance of the motor, the material usage can be minimized and the processing process can be simplified, which can reduce the material cost and processing cost, thereby reducing the overall cost of the product.

[0058] In addition, the existing motor end cover manufactured by one-piece molding often lacks a structure for motor heat dissipation. In the embodiment of the present application, the motor end cover includes multiple sub-components, and the space between the sub-components can be used for motor heat dissipation, thereby improving the heat dissipation effect of the motor and ensuring that the motor can operate normally.

[0059] In one or more embodiments, at least one of the sub-components of the motor end cover has a cylindrical portion for arranging a bearing, thereby enabling reliable installation of the bearing.

[0060] Figure 7 yes Figure 2 A schematic diagram of another angle of the sub-component shown, such as Figure 7 As shown, the bearing 15 may be provided on the cylindrical portion 16 of the subassembly 11 .

[0061] That is to say, if Figure 1 、 Figure 2 and Figure 5 As shown, the sub-component 11 may have a cylindrical portion 16 for setting the bearing 15, but the present application is not limited to this. A cylindrical portion for setting the bearing 15 may also be set in the sub-component 12, or cylindrical portions may be set in both the sub-component 11 and the sub-component 12. In addition, when the motor end cover 10 includes at least 3 sub-components, at least one of the at least 3 sub-components may be provided with a cylindrical portion, which will not be exemplified one by one here.

[0062] Take the cylindrical portion 16 being provided on the sub-component 11 as an example, Figure 1 and Figure 2 As shown, the sub-component 11 may include a main body 17 , a connecting portion 18 is provided between the main body 17 and the legs 13 , and the cylindrical portion 16 may be provided at a radially inner portion of the main body 17 .

[0063] In one or more embodiments, the cylindrical portion may be disposed in the middle of the subassembly. This allows for stable support of the bearing. For example, Figure 1 and Figure 2 As shown, two opposite positions on the outer periphery of the main body 17 are respectively provided with connecting portions 18, that is, the main body 17 is located in the middle position of the sub-component 11, and the cylindrical portion 16 is located at the radial inner side of the main body 17. Thus, the cylindrical portion 16 is provided in the middle position of the sub-component 11. In the embodiment of the present application, as shown in FIG. Figure 1 and Figure 2 As shown, the cylindrical portion 16 includes a through hole that passes through the sub-component, but the present application is not limited to this. The cylindrical portion 16 can also be a structure with an open side and a bottom on the other side. The present application does not impose any restrictions on this, as long as the cylindrical portion 16 has space for setting a bearing.

[0064] In one or more embodiments, at least one of the subassemblies of the motor end cover has an assembly portion for detachable assembly of the subassemblies of the motor end cover, thereby enabling assembly of all subassemblies of the motor end cover and ensuring the overall reliability of the motor end cover.

[0065] The embodiment of the present application does not limit the shape of the assembly portion. In some embodiments, the assembly portion may include a concave portion and a convex portion respectively provided on two sub-components assembled with each other. Figures 1 to 3As shown, the sub-component 11 and the sub-component 12 respectively have a first assembly portion 19 in the shape of a through hole as a concave portion and a second assembly portion 20 in the shape of a convex portion as a convex portion. That is to say, the assembly portion may include concave and convex matching structures that cooperate with each other, but the present application is not limited to this. For example, the assembly portion may be a snap-fit ​​structure that realizes assembly in a snap-fit ​​manner, and the snap-fit ​​structure may be provided on at least one of the sub-component 11 and the sub-component 12. For another example, the assembly portion may be an adhesive component provided on at least one of the sub-component 11 and the sub-component 12.

[0066] The embodiment of the present application does not limit the number of assembly parts. For example, Figures 1 to 3 As shown, there are three first assembly parts 19 and three second assembly parts 20 , but the present application is not limited thereto. The number of first assembly parts 19 (second assembly parts 20 ) can be one, two, four, or more than four.

[0067] In one or more embodiments, Figures 1 to 3 As shown, the sub-assembly 11 and the sub-assembly 12 are provided with a first assembly portion 19 and a second assembly portion 20, respectively, and the sub-assembly 11 and the sub-assembly 12 can be detachably assembled through the first assembly portion 19 and the second assembly portion 20. However, the present application is not limited thereto, and an assembly portion can be provided only on the sub-assembly 11 or the sub-assembly 12 to achieve detachable assembly between the sub-assembly 11 and the sub-assembly 12. For example, a snap-fit ​​structure can be provided on the sub-assembly 11 to snap-fit ​​the sub-assembly 12, or a snap-fit ​​structure can be provided on the sub-assembly 12 to snap-fit ​​the sub-assembly 11, or snap-fit ​​structures for snapping each other can be provided on both the sub-assembly 11 and the sub-assembly 12. In addition, when the motor end cover 10 includes at least three sub-assemblies, at least one of the at least three sub-assemblies can be provided with an assembly portion, which will not be listed one by one here.

[0068] In the embodiment of the present application, there is no restriction on the setting position of the assembly part. Taking the sub-component 11 and the sub-component 12 as an example, in which the first assembly part 19 and the second assembly part 20 are respectively provided, the first assembly part 19 can be provided on the main body 17 of the sub-component 11, and the first assembly part 19 can be provided at a position radially outside of the main body 17, such as the cylindrical part 16. When there are multiple first assembly parts 19, the multiple first assembly parts 19 can be provided at equal or unequal intervals along the circumferential direction, and the second assembly part 20 is provided on the sub-component 12 at a position opposite to the first assembly part 19.

[0069] In one or more embodiments, at least one of the subassemblies of the motor end cap has a hub assembly portion for assembly with the wheel hub. This allows the wheel hub to be assembled on the motor, and external devices, such as client devices, can be assembled with the motor via the wheel hub.

[0070] For example, Figure 1 and Figure 2 As shown, the hub assembly part 21 is provided on the sub-component 11, but the present application is not limited thereto. The hub assembly part may also be provided on the sub-component 12, or simultaneously provided on the sub-component 11 and the sub-component 12. In addition, when the motor end cover 10 includes at least 3 sub-components, at least one of the at least 3 sub-components may be provided with a hub assembly part, which are not listed one by one here.

[0071] like Figure 1 and Figure 2 As shown, the hub assembly portion 21 can be provided on the main body portion 17 of the subassembly 11, for example, the hub assembly portion 21 is provided at a position radially outward of the first assembly portion 19 of the main body portion 17. Figure 2 As shown, the hub assembly portion 21 includes an annular portion surrounding the outer circumference of the cylindrical portion 16. The annular portion is provided with one or more bayonet holes 211, through which the hub can be assembled. In the embodiment of the present application, there is no limitation on the specific shape of the bayonet holes 211. In addition, the hub assembly portion 21 is not limited to being assembled with the hub via bayonet holes. The hub assembly portion 21 can have other shapes as long as it can be assembled with the hub.

[0072] In the embodiment of the present application, there is no limit on the number of the bayonet 211. For example, Figure 2 FIG2 shows two bayonet holes 211 , but the present application is not limited thereto. The number of bayonet holes 211 may be three or more, and the plurality of bayonet holes may be arranged at equal intervals along the axial direction.

[0073] In one or more embodiments, at least one of the subassemblies of the motor end cap is provided with a junction box assembly portion for assembly with a junction box, thereby enabling connection of cables of the motor and external devices (e.g., a power supply, a client device), wherein the cables may include power cables and / or signal cables.

[0074] For example, Figure 1 、 Figure 3 and Figure 4 As shown, the junction box assembly portion 23 can be provided on the sub-component 12, but the present application is not limited thereto. The junction box assembly portion 23 can also be provided on the sub-component 11, or simultaneously provided on the sub-component 11 and the sub-component 12. In addition, when the motor end cover 10 includes at least 3 sub-components, at least one of the at least 3 sub-components can be provided with a junction box assembly portion, which are not listed one by one here.

[0075] Taking the example of the junction box assembly part 23 being set on the sub-component 12, similar to the shape of the sub-component 11, the sub-component 12 can also have a main body 24 and a connecting part 25, and the connecting part 25 is set between the main body 24 and the support leg 14. The junction box assembly part 23 can be set on the connecting part 25 of the sub-component 12.

[0076] In one or more embodiments, the junction box assembly portion includes a flat plate portion for arranging the junction box and a connecting portion for connecting the subassembly and the flat plate portion, such as Figure 3 As shown, the junction box assembly portion 23 includes a flat plate portion 231 and a connecting portion 232. The flat plate portion 231 is used to set the junction box, and the connecting portion 232 connects the connecting portion 25 of the subassembly 12 and the flat plate portion 231. In this way, the junction box can be reliably set.

[0077] In the embodiments of this application, Figure 3 As shown, the connecting portion 25 may include a bending structure, and the connecting portion 232 may be arranged in the bending structure, thereby improving the connection reliability of the junction box assembly portion 23 relative to the sub-component, thereby further improving the reliability of the junction box setting.

[0078] In the embodiment of the present application, there is no limitation on the shape of the legs. For example, the cross-sectional shape of the legs can be at least one of the following: U-shaped, W-shaped, N-shaped, or the cross-sectional shape of the legs can be other shapes.

[0079] In one or more embodiments, at least one leg of the motor end cover 10 is provided with a reinforcement portion, thereby increasing the strength of the motor end cover 10 .

[0080] For example, Figures 1 to 2 As shown, the legs 13 of the subassembly 11 may be provided with reinforcing ribs 26. In addition, as shown Figure 3 and Figure 4 As shown, the legs 14 of the sub-component 12 may also be provided with reinforcing ribs 26, but the present application is not limited thereto. For example, the reinforcing ribs may be provided only on the sub-component 11 or the sub-component 12. Figures 1 to 4 As shown, the respective connecting portions 18 and 25 of the sub-assembly 11 and the sub-assembly 12 may also be provided with reinforcing ribs 26 , thereby further enhancing the strength of the motor end cover 10 .

[0081] In one or more embodiments, the reinforcement portion may extend along the length direction of the leg, thereby further improving the strength of the motor end cover. Figures 1 to 4 As shown, the reinforcing ribs 26 serving as the reinforcement portion can extend along the length of the leg. Furthermore, if the connecting portions 18 and 25 are also provided with reinforcing ribs 26, the reinforcing ribs can also extend along the length of the connecting portions 18 and 25. In other words, the reinforcing ribs on the subassemblies 11 and 12 can extend along the length of the subassemblies. This can further enhance the strength of the motor end cover.

[0082] In the embodiments of the present application, there is no restriction on the number of reinforcing parts. For example, for any sub-component, such as sub-component 11, the reinforcing ribs 26 may extend parallel to the length direction on both sides of the leg 13 and the connecting part 18, but is not limited thereto. For example, the sub-component 11 may also be provided with only one reinforcing rib, or three reinforcing ribs, and the present application does not impose any restriction on this.

[0083] In the embodiment of the present application, there is no limitation on the specific shape of the reinforcement portion. For example, Figure 2 As shown, the reinforcement portion can be a strip-shaped portion protruding from the leg 13 and the connecting portion 18, but the present application is not limited thereto. For example, Figure 3 and Figure 4 As shown, the reinforcement portion may be in a curved shape and extend along the length of the support leg 13 and the connecting portion 25 , thereby improving the strength of the motor end cover.

[0084] In one or more embodiments, at least one of the sub-components of the motor end cover 10 has a grease storage portion for storing grease, thereby enabling reliable oil supply to the bearing 15 and ensuring the performance of the motor.

[0085] For example, Figure 3 As shown, the grease reservoir 27 can be provided on the subassembly 12. For example, the grease reservoir 27 can be provided on the main body 24 of the subassembly 12. In other words, the grease reservoir can be provided in the middle of the subassembly 12. In addition, the grease reservoir 27 can be in the shape of a groove for storing grease. In addition, the grease reservoir can also be provided on the subassembly 11, or both the subassembly 11 and the subassembly 12 can be provided with grease reservoirs.

[0086] In the embodiments of this application, Figure 1 As shown, the main body 17 of the sub-component 11 and the main body 24 of the sub-component 12 can overlap in the axial direction OO', and the grease storage portion 27 can be located radially outside the main body 17 of the sub-component 11, so that the grease stored in the grease storage portion 27 can enter the bearing 15 by volatilization.

[0087] The following description will be made by taking the case where the grease storage portion 27 is provided in the sub-component 12 as an example.

[0088] like Figure 4 As shown, in one or more embodiments, the subassembly 12 may further be provided with a deformable cover plate 28 for fixing the bearing 15. In this way, the bearing can be supported to improve the reliability of the motor.

[0089] In the embodiment of the present application, the deformable cover plate 28 is disposed inside the grease storage portion 27. Thus, the reliable arrangement of the bearing 15 can be further enhanced while achieving precise assembly.

[0090] In the embodiment of the present application, the deformable cover plate 28 may be made of a deformable material, or the deformable cover plate 28 may be a deformable structure made of metal, for example, Figure 4 As shown, the deformable cover plate 28 is in the form of a sheet with a bent shape, which is not limited in the present application.

[0091] In one or more embodiments, Figure 3 and Figure 4 As shown, the deformable cover plate 28 includes a first component 281 connected to the grease reservoir 27 and a second component 282 that contacts the bearing. The first component 281 and the second component 282 extend in different directions. For example, the first component 281 extends in a direction perpendicular to the axial direction, while the second component 282 extends in the axial direction. In other words, the second component 282 can extend in a desired direction to fully abut the bearing, thereby improving the assembly effect. However, the present application is not limited to this. For example, the deformable cover plate can be an entire arc-shaped plate, with one end disposed in the grease reservoir 27 and the other end configured to abut the bearing 15.

[0092] In the embodiments of this application, Figure 4 As shown, there can be three deformable cover plates 28, but the present application is not limited thereto. The number of deformable cover plates 28 can also be two, four or more than four, and multiple deformable cover plates 28 can be arranged at equal intervals along the circumferential direction.

[0093] In one or more embodiments, Figure 4 As shown, the deformable cover 28 is provided with a hole 29 for fixing the subassembly 12 to the motor. Figure 4 The hole 29 is shown to pass through the deformable cover plate 28 along the axial direction OO'. Therefore, when the motor end cover 10 is assembled with other components of the motor, such as the stator core, the motor end cover 10 and other components of the motor can be further fixed through the hole 29.

[0094] In one or more embodiments, Figure 4 As shown, the hole 29 is provided in the first part 281 of the deformable cover plate 28. Thus, since the first part 281 and the second part 282 extend in different directions, when the hole 29 provided in the first part 281 is used to fix with other parts of the motor, it is possible to avoid affecting the assembly effect of the second part 282 and the bearing 15.

[0095] In one or more embodiments, Figure 3 As shown, in the sub-component 12, the second assembly part 20 can be arranged in the grease storage part 27. For example, the second assembly part 20 is arranged at a radially inner position of the grease storage part 27, but the present application is not limited to this. The second assembly part 20 can also be arranged at other positions of the grease storage part 27.

[0096] It is worth noting that the above Figures 1 to 7 Only the motor end cover of the embodiment of the present application is schematically described, but the present application is not limited thereto, and the specific contents of each structure or component can also refer to the relevant technology; in addition, Figures 1 to 7 Structures or components not shown, or reduced Figures 1 to 7 One or more structures or components in a. Figures 1 to 7 For components or elements not specifically specified, reference may be made to the relevant technology, and this application does not limit this.

[0097] It can be seen from the above embodiments that the motor end cover includes at least two sub-components assembled in a detachable manner. Therefore, without affecting the performance of the motor, the material usage can be minimized and the processing process can be simplified, which can reduce the material cost and processing cost, thereby reducing the overall cost of the product.

[0098] Embodiments of the second aspect

[0099] An embodiment of the second aspect of the present application provides a motor. Figure 8 This is a schematic diagram of a motor according to an embodiment of the second aspect of the present application.

[0100] like Figure 8 As shown, the motor 100 includes a motor end cover 10 as described in the embodiment of the first aspect, which is arranged on at least one side of the axial direction of the motor 100. Regarding the motor end cover 10, please refer to the description of the embodiment of the first aspect, the content of which is incorporated herein and will not be repeated here.

[0101] like Figure 8 As shown, the motor 100 may include a rotating shaft 101, a rotor 102 and a stator 103, and the motor end cover 10 may be arranged on both sides of the axial direction of the motor 100, but the present application is not limited thereto, and the motor end cover 10 may also be arranged only on one side of the axial direction of the motor 100.

[0102] like Figure 8 As shown, in the embodiment of the present application, the stator 103 may include a stator core 104, and the motor end cover 10 may be fixed to the stator core 104 via a fixing assembly portion, for example, by having a fixing member 105 pass through the fixing assembly portion to achieve fixation, and the fixing member 105 may be a rivet, etc. In this way, the motor end cover 10 can be assembled and fixed to other components of the motor 100.

[0103] However, the present application is not limited to this. For example, when motor end covers 10 are provided on both axial sides of the motor 100, the motor end cover on one axial side can be fixed to the motor end cover on the other axial side, thereby realizing the assembly and fixation of the motor end cover 10 relative to other components of the motor.

[0104] In the embodiment of the present application, the motor 100 can be applied to various electrical appliances, such as a washing machine, and the present application does not limit this.

[0105] The embodiments of the present application are described above in conjunction with specific implementation methods, but those skilled in the art should be aware that these descriptions are exemplary and do not limit the scope of protection of the embodiments of the present application. Those skilled in the art can make various variations and modifications to the embodiments of the present application based on the spirit and principles of the embodiments of the present application, and these variations and modifications are also within the scope of the embodiments of the present application.
