Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a motor and a clothing processing device. Background Technology

[0002] Currently, washing machines or dryers are equipped with plastic-coated motors, which have output shafts. A secondary transmission mounting base extends from the outer casing of the plastic-coated motor, and a secondary transmission structure is installed on the secondary transmission mounting base. The secondary transmission structure is used to cooperate with the output shaft for transmission.

[0003] When the mounting structure used to cooperate with the motor is changed, the structure of the mounting base needs to be changed, which requires new molds to be made, and the mounting base and housing need to be re-processed, resulting in an increase in the processing cost of the motor. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, in a first aspect, the present invention proposes an electric motor, comprising: a housing, with an opening on one side of the housing; a stator, a rotor, and a drive shaft, wherein the stator is fixed to the housing, the rotor is rotatable relative to the stator, and the rotor is sleeved on the drive shaft; an end cover, detachably connected to the housing, the end cover sealing the opening; a mounting base, connected to the end cover; and a transmission assembly, disposed on the mounting base, the transmission assembly being used for transmission connection with the drive shaft.

[0006] The housing has an opening through which some components of the motor can be installed. An end cover is connected to the housing and can close the opening to seal the interior. The end cover can also be removed from the housing for easy maintenance of the interior. The stator and rotor cooperate with each other; the rotor can rotate relative to the stator, driving the drive shaft to rotate.

[0007] The end cover is connected to a mounting base, and the mounting base is equipped with a transmission component. The transmission component is connected to the drive shaft, and the drive shaft can drive the transmission component to rotate, so that the transmission component can realize two-stage transmission, thereby changing the overall output speed and output torque of the motor.

[0008] In this design, the mounting base is placed on the end cover. When the mounting structure that mates with the motor changes, the structure of the mounting base needs to be modified accordingly. In this case, the end cover can be removed from the housing, and then the mounting base and end cover can be re-machined. Since the mounting base is placed on the end cover, there is no need to re-mold the housing. The structure of the mounting base and end cover is simpler than that of the housing, which facilitates the re-machining of the mounting base and end cover, reduces the difficulty and cost of re-machining structural components, and thus reduces the processing cost of the motor.

[0009] In some technical solutions, the mounting base may optionally be integrally formed with the end cap.

[0010] The mounting base and end cap are integrally molded. When reprocessing the mounting base, the reprocessed mounting base and end cap can be obtained in one go, instead of processing the mounting base and end cap separately and then connecting them. This processing method can reduce the processing difficulty of the mounting base and end cap. Moreover, if a new mold is required, only one mold needs to be made, instead of making new molds for the mounting base and end cap separately, effectively controlling processing costs.

[0011] In some technical solutions, optionally, the first end of the drive shaft extends out of the first side of the housing, the length of the drive shaft extending out of the first side of the housing is L1, the second end of the drive shaft extends out of the second side of the housing, the length of the drive shaft extending out of the second side of the housing is L2, L1 is greater than L2, and the end cap is connected to the second side of the housing.

[0012] One end of the drive shaft extends out of the first side of the housing, and the other end extends out of the second side of the housing. The length of the drive shaft extending out of the first side of the housing is longer, and the length extending out of the second side of the housing is shorter. In related technologies, end caps are usually mounted on the second side of the housing, and mounting bases are usually located on the second side of the housing to facilitate the connection between the transmission assembly and the load.

[0013] Since the mounting base is placed on the end cover in this design, the end cover is located on the second side of the housing for the motor in this design. This makes it easy to place the mounting base on the end cover. Both the end cover and the mounting base are located on the second side of the housing. This arrangement does not require major structural modifications to the mounting base, thereby reducing the processing difficulty of the mounting base.

[0014] In some technical solutions, optionally, one of the housing and the end cap is provided with a positioning element, and the other is provided with a positioning hole, with the positioning element inserted into the positioning hole.

[0015] During the installation of the end cap onto the housing, the positioning component is inserted into the positioning hole. The positioning component can play a role in positioning and limiting, which can not only ensure the accuracy of the installation position of the end cap, but also prevent the end cap from moving relative to the housing, thereby ensuring the installation stability of the end cap.

[0016] In some technical solutions, optionally, the housing is provided with a plurality of first connecting parts in the circumferential direction, and the end cap is provided with a plurality of second connecting parts in the circumferential direction, the plurality of first connecting parts and the plurality of second connecting parts correspond one-to-one, and the second connecting parts are detachably connected to the first connecting parts.

[0017] The housing is provided with multiple first connecting parts, which are distributed at intervals along the circumference of the housing. The end cap is provided with multiple second connecting parts, which are distributed at intervals along the circumference of the end cap. When one first connecting part is connected to one second connecting part, and multiple first connecting parts and multiple second connecting parts are connected to each other, the end cap is subjected to multiple forces in the circumference, which helps to improve the connection stability between the end cap and the housing.

[0018] In some technical solutions, the motor may optionally include screws or connecting pins that connect the second connecting portion to the first connecting portion.

[0019] The second connecting part can be connected to the first connecting part using screws, or the second connecting part can be connected to the first connecting part using pins, or a portion of the second connecting part can be connected to the first connecting part by screws, and another portion of the second connecting part can be connected to the first connecting part by pins.

[0020] In some technical solutions, optionally, a plurality of first connecting portions are disposed on the outer periphery of the housing, and a plurality of second connecting portions are disposed on the outer periphery of the end cap.

[0021] The first connecting part is located on the outer periphery of the housing, so it can fit snugly against the side of the housing, providing a large contact area between the first connecting part and the housing, thus ensuring the stability of the connection between them. To accommodate the first connecting part, multiple second connecting parts are located on the outer periphery of the end cap.

[0022] In some technical solutions, the transmission assembly may optionally include: a connecting shaft, one end of which is interference-fitted with the mounting base; a ball bearing, sleeved on the connecting shaft; and a transmission wheel, which is interference-fitted with the ball bearing and is connected to the drive shaft for transmission.

[0023] The connecting shaft is fixed to the mounting base by an interference fit. The roller bearing is sleeved on the connecting shaft, and the transmission wheel is sleeved on the ball bearing, so that the transmission wheel can rotate relative to the connecting shaft. The drive shaft can drive the transmission wheel to rotate, and the transmission wheel can drive the load to rotate.

[0024] In some technical solutions, the housing and stator can optionally be injection molded as a single unit.

[0025] The housing and stator are processed by integral injection molding, which facilitates the processing of the housing and stator and reduces the processing difficulty of the motor.

[0026] In some technical solutions, the housing may optionally be a bulk molding compound housing; and / or the end cap may be a cast aluminum end cap, and the mounting base may be a cast aluminum mounting base.

[0027] The cost of re-molding bulk molding compounds is relatively high, while the processing cost of cast aluminum parts is relatively low. Therefore, cast aluminum materials can be used to process end caps and mounting bases. In addition, the production capacity of bulk molding compound molds is lower than that of cast aluminum parts. Using cast aluminum materials to process end caps and mounting bases is beneficial to improving production capacity.

[0028] Secondly, this utility model proposes a garment processing device, including: the motor mentioned in the first aspect.

[0029] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] The following reference Figures 1 to 4 This invention describes a motor and clothing processing device provided according to some embodiments of the present invention.

[0040] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a motor 100 is proposed. The motor 100 includes: a housing 110, an end cover 150, a mounting base 160, a transmission assembly 170, a stator 120, a rotor 130, and a drive shaft 140. An opening 111 is provided on one side of the housing 110. The end cover 150 is detachably connected to the housing 110 and covers the opening 111. The stator 120 is fixed to the housing 110, and the rotor 130 is rotatable relative to the stator 120. The rotor 130 is sleeved on the drive shaft 140. The mounting base 160 is connected to the end cover 150, and the transmission assembly 170 is disposed on the mounting base 160. The transmission assembly 170 is used for transmission connection with the drive shaft 140.

[0041] The housing 110 has an opening 111 through which some components of the motor 100 can be installed. An end cover 150 is connected to the housing 110 and can close the opening 111, thus sealing the interior of the housing 110. The end cover 150 can be removed from the housing 110 for easy maintenance of the interior. The stator 120 and rotor 130 cooperate with each other, with the rotor 130 rotating relative to the stator 120, driving the drive shaft 140 to rotate.

[0042] An mounting base 160 is connected to the end cover 150. A transmission assembly 170 is provided on the mounting base 160. The transmission assembly 170 is connected to the drive shaft 140. The drive shaft can drive the transmission assembly 170 to rotate, so that the transmission assembly 170 can realize two-stage transmission, thereby changing the overall output speed and output torque of the motor 100.

[0043] In this design, the mounting base 160 is mounted on the end cover 150. When the mounting structure that mates with the motor 100 changes, the structure of the mounting base 160 needs to be modified accordingly. In this case, the end cover 150 can be disassembled from the housing 110, and then the mounting base 160 and the end cover 150 can be re-processed. Since the mounting base 160 is mounted on the end cover 150, it is not necessary to re-mold the housing 110. The structure of the mounting base 160 and the end cover 150 is simpler than that of the housing 110, which facilitates the re-processing of the mounting base 160 and the end cover 150, reducing the difficulty and cost of re-processing structural components, thereby reducing the processing cost of the motor 100.

[0044] In some embodiments, the mounting base 160 is optionally integrally formed on the end cap 150.

[0045] The mounting base 160 and the end cap 150 are integrally formed. When reprocessing the mounting base 160, the reprocessed mounting base 160 and end cap 150 can be obtained in one go, instead of processing the mounting base 160 and end cap 150 separately and then connecting them. This processing method can reduce the processing difficulty of the mounting base 160 and end cap 150. Moreover, if a new mold is required, only one mold needs to be made, instead of making new molds for the mounting base 160 and end cap 150 separately, effectively controlling processing costs.

[0046] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the first end of the drive shaft 140 extends out of the first side of the housing 110, the length of the drive shaft 140 extending out of the first side of the housing 110 is L1, the second end of the drive shaft 140 extends out of the second side of the housing 110, the length of the drive shaft 140 extending out of the second side of the housing 110 is L2, L1 is greater than L2, and the end cap 150 is connected to the second side of the housing 110.

[0047] One end of the drive shaft 140 extends out of the first side of the housing 110, and the other end of the drive shaft 140 extends out of the second side of the housing 110. The length of the drive shaft 140 extending out of the first side of the housing 110 is longer, and the length of the drive shaft 140 extending out of the second side of the housing 110 is shorter. In related art, the end cap 150 is usually mounted on the second side of the housing 110, and in order to connect the transmission assembly 170 to the load, the mounting base 160 is usually provided on the second side of the housing 110.

[0048] Since the mounting base 160 is set on the end cover 150 in this solution, the end cover 150 is set on the second side of the housing 110 for the motor 100 in this solution, which makes it easy to set the mounting base 160 on the end cover 150. Both the end cover 150 and the mounting base 160 are located on the second side of the housing 110. This arrangement does not require major structural modifications to the mounting base 160, thereby reducing the processing difficulty of the mounting base 160.

[0049] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, one of the housing 110 and the end cap 150 is provided with a positioning element 181, and the other is provided with a positioning hole 182, with the positioning element 181 inserted into the positioning hole 182.

[0050] During the process of installing the end cap 150 into the housing 110, the positioning member 181 is inserted into the positioning hole 182. The positioning member 181 can play the role of positioning and limiting, which can ensure the accuracy of the installation position of the end cap 150 and prevent the end cap 150 from moving relative to the housing 110, thereby ensuring the installation stability of the end cap 150.

[0051] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the housing 110 is provided with a plurality of first connecting portions 183 in the circumferential direction, and the end cap 150 is provided with a plurality of first connecting portions 183 in the circumferential direction. Figure 4 The arrow at point C indicates that the circumferential direction of the housing 110 is the same as that of the end cap 150. Multiple second connecting parts 184 are provided, and multiple first connecting parts 183 and multiple second connecting parts 184 correspond one-to-one. The second connecting parts 184 are detachably connected to the first connecting parts 183.

[0052] The housing 110 is provided with a plurality of first connecting parts 183, which are distributed at intervals along the circumference of the housing 110. The end cover 150 is provided with a plurality of second connecting parts 184, which are distributed at intervals along the circumference of the end cover 150. One first connecting part 183 is connected to one second connecting part 184. When the plurality of first connecting parts 183 and the plurality of second connecting parts 184 are connected to each other, the end cover 150 is subjected to forces at multiple points in the circumference, which helps to improve the connection stability between the end cover 150 and the housing 110.

[0053] In some embodiments, the motor 100 may optionally include screws or connecting pins that connect the second connecting portion 184 to the first connecting portion 183.

[0054] The second connecting part 184 can be connected to the first connecting part 183 using screws, or the second connecting part 184 can be connected to the first connecting part 183 using pins, or a portion of the second connecting part 184 can be connected to the first connecting part 183 by screws, and another portion of the second connecting part 184 can be connected to the first connecting part 183 by pins.

[0055] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, a plurality of first connecting portions 183 are disposed on the outer periphery of the housing 110, and a plurality of second connecting portions 184 are disposed on the outer periphery of the end cap 150.

[0056] The first connecting portion 183 is disposed on the outer periphery of the housing 110, so the first connecting portion 183 can fit against the side of the housing 110, and there is a large contact area between the first connecting portion 183 and the housing 110, ensuring the connection stability between the first connecting portion 183 and the housing 110. In order to adapt to the first connecting portion 183, a plurality of second connecting portions 184 are disposed on the outer periphery of the end cover 150.

[0057] Combination Figure 2 and Figure 4 As shown, in some embodiments, optionally, the transmission assembly 170 includes: a connecting shaft 191, a ball bearing 192, and a transmission wheel 193. One end of the connecting shaft 191 is interference-fitted with the mounting base 160, the ball bearing 192 is sleeved on the connecting shaft 191, the transmission wheel 193 is interference-fitted with the ball bearing 192, and the transmission wheel 193 is connected to the drive shaft 140 for transmission.

[0058] The connecting shaft 191 is fixed to the mounting base 160 by an interference fit. The roller bearing is sleeved on the connecting shaft 191, and the transmission wheel 193 is sleeved on the ball bearing 192, so that the transmission wheel 193 can rotate relative to the connecting shaft 191. The drive shaft 140 can drive the transmission wheel 193 to rotate, and the transmission wheel 193 can drive the load to rotate.

[0059] In some embodiments, the housing 110 and the stator 120 are optionally integrally injection molded.

[0060] The housing 110 and the stator 120 are processed by integral injection molding, which facilitates the processing of the housing 110 and the stator 120 and reduces the processing difficulty of the motor 100.

[0061] In some embodiments, the housing 110 may be a bulk molding compound housing, and / or the end cap 150 may be a cast aluminum end cap, and the mounting base 160 may be a cast aluminum mounting base.

[0062] The cost of re-molding bulk molding compounds is relatively high, while the processing cost of cast aluminum parts is relatively low. Therefore, cast aluminum materials can be used to process end caps 150 and mounting bases 160. In addition, the production capacity of bulk molding compound molds is lower than that of cast aluminum parts. Using cast aluminum materials to process end caps 150 and mounting bases 160 is beneficial to improving production capacity.

[0063] This embodiment proposes an integrated BMC plastic-coated motor 100 with enhanced compatibility. Typically, changes to the mounting structure of the motor 100 include changes to the front and rear mounting span, and changes to the front and rear positions, shapes, and angles of the secondary transmission structure. To avoid modifying the entire BMC mold, the secondary transmission structure can be combined with the BB cover and separated from the BMC housing to form a detachable part. The BB cover and the BMC housing are locked together with screws.

[0064] The secondary transmission structure is combined with the BB (Bearing Block) cover and separated from the BMC (Bulk Molding Compound) housing to form a detachable part. The BB cover (end cover 150) is locked to the BMC housing with three screws. There is a pin on the BMC housing that can be inserted into the pin hole on the BB cover to distribute the force borne by the screw hole of the BB cover and enhance the reliability of the structure.

[0065] The secondary transmission structure (mounting base 160 and transmission assembly 170) is combined with the BB cover and separated from the BMC housing to form a detachable part. When dealing with changes in the mounting structure of the motor 100, only one mold for the cast aluminum part needs to be made, instead of making the entire BMC mold. This reduces mold costs and enhances the compatibility and versatility of the motor 100 in different usage scenarios.

[0066] This embodiment provides a BMC-coated dryer motor 100 with a detachable two-stage transmission structure for enhanced compatibility. It includes a BMC housing 110, which is secured to a BB cover with screws. An extension of the BB cover is a mounting base 160 for the two-stage transmission. The mounting base 160 is connected to a pulley (drive wheel 193) via a connecting shaft 191. The two-stage transmission structure, combined with the BB cover, forms a detachable part, enhancing the compatibility and versatility of the motor 100 and reducing mold costs when changing the mounting structure of the motor 100.

[0067] The BMC housing and stator 120 are integrally injection molded. Bearings are installed inside the BMC housing and BB cover. The rotor 130 is installed in the closed space formed by the BMC housing and BB cover, and the drive shaft 140 is placed on the bearing.

[0068] Mounting base 160 and BB cover are integrated as a single unit, cast in one piece. During assembly, the knurled side of connecting shaft 191 is pressed into the hole of mounting base 160, with an interference fit between connecting shaft 191 and mounting base 160. The other side of connecting shaft 191 is connected to transmission wheel 193 via two ball bearings 192, forming a moving part. The ball bearings 192 and transmission wheel 193 are also interference fit. Mounting base 160, connecting shaft 191, ball bearings 192, and transmission wheel 193 constitute a two-stage transmission structure.

[0069] The BMC housing has a pin on its mounting surface and three mounting ears on its outer peripheral wall. The BB cover has three screw holes extending from its outer circumference, and a pin hole is also provided. The screw passes through the screw holes and mounting ears, and the BB cover and BMC housing are locked together with a nut. At the same time, the pin is inserted into the pin hole during assembly. The cooperation between the pin and the pin hole can improve the assembly accuracy, share the force borne by the mounting ears and screw holes, and enhance the reliability of the motor.
