[0060] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0061] The following is for reference. Figures 1-17 The present invention describes a motor 100 according to an embodiment of the present invention. The motor 100 can be installed inside an air conditioner, but the present invention is not limited thereto. The motor 100 can also be installed on other devices, such as refrigerators, vehicles, etc., which require the installation of the motor 100. This application describes the motor 100 installed inside an air conditioner as an example.

[0062] According to a first aspect of the present invention, a motor 100 includes: a housing 10, a partition 20, a motor assembly 30, an electronic control board 40, and an electrical connector 50. The housing 10 defines a mounting cavity 11, and the partition 20 is disposed within the mounting cavity 11 to divide the mounting cavity 11 into a first sub-mounting cavity 12 and a second sub-mounting cavity 13. The motor assembly 30 is disposed within the first sub-mounting cavity 12. The electronic control board 40 and the electrical connector 50 are disposed within the second sub-mounting cavity 13, and the electrical connector 50 connects the electronic control board 40 and the motor assembly 30.

[0063] The outer casing 10 contains a mounting cavity 11, which can be a closed cavity. A conductive partition 20, which can be made of metal, is disposed within the mounting cavity 11. The partition 20 can be constructed as a plate and can be fixedly connected to the outer casing 10. The partition 20 divides the mounting cavity 11 into a first sub-mounting cavity 12 and a second sub-mounting cavity 13, located on opposite sides of the partition 20. The motor assembly 30 includes a stator mechanism 32 and a rotor mechanism 31. The stator mechanism 32 and the rotor mechanism 31 are both disposed within the first sub-mounting cavity 12. The stator mechanism 32 surrounds the rotor mechanism 31, i.e., the stator mechanism 32 is sleeved on the outside of the rotor mechanism 31. The motor shaft 311 of the rotor mechanism 31 passes through the outer casing 10 and extends out of the outer casing 10. Both the control board 40 and the electrical connector 50 are located within the second sub-mounting cavity 13. The electrical connector 50 can be a wire harness or a three-phase winding power supply line. The electrical connector 50 connects the control board 40 and the motor assembly 30. Further, one end of the electrical connector 50 is connected to the control board 40, and the other end is connected to the winding coil of the stator mechanism 32. The other end of the electrical connector 50 can be directly connected to the winding coil, or it can be connected to the winding coil of the stator mechanism 32 via an adapter 80. As an example, the motor 100 includes an adapter 80, which can be fixed to the housing 10 or the separator 20. Both ends of the adapter 80 are located within the first sub-mounting cavity 12 and the second sub-mounting cavity 13, respectively. The other end of the electrical connector 50 is welded to the adapter 80, and the adapter 80 is connected to the winding coil of the stator mechanism 32. Furthermore, the electrical connector 50 has a first plug-in terminal, and the electrical control board 40 has a second plug-in terminal. The first plug-in terminal and the second plug-in terminal are plugged in and engaged to realize the electrical connection between the electrical connector 50 and the electrical control board 40.

[0064] The first sub-mounting cavity 12 and the second sub-mounting cavity 13 are separated by the separator 20. The electrical connector 50 and the rotor mechanism 31 are located in the first sub-mounting cavity 12 and the second sub-mounting cavity 13, respectively. This separation effectively prevents friction between the electrical connector 50 and the rotor mechanism 31, thus effectively solving the problem of damage to the electrical connector 50 caused by friction between the rotor mechanism 31 and the electrical connector 50. Furthermore, when the electrical connector 50 is welded to the adapter 80, the separator 20 prevents weld slag from falling into the first sub-mounting cavity 12 during the welding process, reducing the risk of the motor 100 jamming or being damaged due to weld slag falling between the stator mechanism 32 and the rotor mechanism 31.

[0065] Therefore, by setting the separator 20, the motor assembly 30 and the electrical connector 50 can be separated, which can prevent the rotor mechanism 31 of the motor assembly 30 and the electrical connector 50 from rubbing together, effectively solving the problem of damage to the electrical connector 50. In addition, it can prevent welding slag from falling into the first sub-mounting cavity 12 during the welding process of the electrical connector 50, reducing the risk of the motor 100 jamming and being damaged due to welding slag falling into the first sub-mounting cavity 12.

[0066] In some embodiments of the present invention, when the motor 100 is installed inside an air conditioner, the air conditioner has a whole-unit electronic control unit. The electronic control board 40 is formed with a motor 100 electronic control unit and a whole-unit electronic control unit. The motor 100 electronic control unit and the whole-unit electronic control unit can be integrated on the same electronic control board 40. The motor 100 electronic control unit can be located on one side of the electronic control board 40, and the whole-unit electronic control unit can be located on the other side of the electronic control board 40. The motor 100 electronic control unit controls the speed of the motor 100 and realizes speed adjustment, etc. The whole-unit electronic control unit can realize the functions of controlling the air conditioner's on / off, temperature, fan speed, mode, etc., and can realize various control operations of the air conditioner by the consumer.

[0067] The motor 100's electrical control unit and the overall machine's electrical control unit are both located inside the motor 100, thus reducing the internal space occupied by the motor 100 and the overall machine's electrical control unit. The three-phase winding power lines are located within the second sub-mounting cavity 13. This placement of the three-phase winding power lines inside the motor 100 prevents corrosion of component pins and other components when the internal environment of the machine is subjected to high temperature and humidity, extending the lifespan of the entire air conditioner. By integrating the motor 100's electrical control unit and the overall machine's electrical control unit onto the same control board 40, and by placing both within the motor 100, integrated electrical control is achieved.

[0068] In some embodiments of the present invention, the separator 20 and the housing 10 are integrally formed. As an example, the housing 10 is a plastic part, and the separator 20 can be integrally injection molded with the housing 10. As another example, the separator 20 can be formed from a portion of the structure of the housing 10. By integrally forming the separator 20 and the housing 10, the connection strength between the separator 20 and the housing 10 can be improved, the risk of separation between the separator 20 and the housing 10 can be reduced, thereby further preventing frictional interference between the rotor mechanism 31 of the motor assembly 30 and the electrical connector 50, and further preventing weld slag generated during the welding process of the electrical connector 50 from falling into the first sub-mounting cavity 12.

[0069] In some embodiments of the present invention, such as Figure 5 and Figure 13 As shown, at least one side of the separator 20 has a first groove 21, and a portion of the outer casing 10 is disposed within the first groove 21.

[0070] Among them, such as Figure 5 and Figure 13 As shown, along the thickness direction of the partition 20, i.e., along the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13, a first groove 21 is formed on one side of the partition 20, or both sides of the partition 20 are provided with the first groove 21. The first groove 21 is formed on the side of the partition 20 facing away from the first sub-mounting cavity 12, and the first groove 21 is recessed into the partition 20. A portion of the outer shell 10 is disposed within the first groove 21, which can improve the bonding force between the partition 20 and the outer shell 10, further reducing the risk of separation between the partition 20 and the outer shell 10. As an example, during the injection molding process of the partition 20 and the outer shell 10, a portion of the outer shell 10 is disposed within the first groove 21 to form an injection-molded riveting structure, improving the connection strength between the partition 20 and the outer shell 10, enhancing the bonding force between the partition 20 and the outer shell 10, and further reducing the risk of separation between the partition 20 and the outer shell 10.

[0071] In some embodiments of the present invention, such as Figure 5 and Figure 13 As shown, the first groove 21 extends circumferentially along the separator 20. The first groove 21 can be arc-shaped or annular. By extending the first groove 21 circumferentially along the separator 20, the area of ​​the first groove 21 is increased, thereby increasing the area of ​​the outer shell 10 within the groove 21. This further enhances the bonding force between the separator 20 and the outer shell 10, and further reduces the risk of separation between them.

[0072] In some embodiments of the present invention, such as Figure 5 and Figure 13 As shown, the separator 20 has a first mounting hole 22, and a portion of the outer casing 10 is disposed in the first mounting hole 22.

[0073] The separator 20 is provided with a first mounting hole 22, which penetrates the separator 20 along its thickness direction. The first mounting hole 22 can be circular, strip-shaped, or polygonal. A portion of the outer shell 10 is disposed within the first mounting hole 22, which further enhances the bonding strength between the separator 20 and the outer shell 10, and further reduces the risk of separation between them. As an example, during the injection molding process of the separator 20 and the outer shell 10, a portion of the outer shell 10 is disposed within the first mounting hole 22 to form an injection-molded riveting structure, further enhancing the connection strength between the separator 20 and the outer shell 10, further improving the bonding strength between them, and further reducing the risk of separation between them.

[0074] In some embodiments of the present invention, such as Figure 5 and Figure 13 As shown, there are multiple first mounting holes 22, which are arranged circumferentially along the separator 20.

[0075] The number of first assembly holes 22 can be two, three, four, five, six, etc. This application uses six first assembly holes 22 as an example for illustration. Multiple first assembly holes 22 are arranged sequentially along the circumference of the separator 20. Further, multiple first assembly holes 22 are arranged evenly along the circumference of the separator 20, with the same spacing between adjacent first assembly holes 22. As an example, during the injection molding process of the separator 20 and the outer shell 10, by setting multiple first assembly holes 22, a portion of the outer shell 10 is disposed at the first assembly holes 22 to form an injection-molded riveting structure, further improving the connection strength between the separator 20 and the outer shell 10, further improving the bonding force between the separator 20 and the outer shell 10, and further reducing the risk of separation between the separator 20 and the outer shell 10.

[0076] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the motor 100 may further include: a conductive element 60; a housing 10 having a first end cap 14 opposite to the separator 20; the separator 20 having a first bearing 15; the first end cap 14 having a second bearing; a motor assembly 30 having a rotor mechanism 31; the rotor mechanism 31 having a motor shaft 311; the motor shaft 311 passing through the second bearing; and the inner end of the motor shaft 311 being assembled to the first bearing 15; the conductive element 60 being disposed in the mounting cavity 11; and the conductive element 60 being connected to both the separator 20 and the first end cap 14.

[0077] The conductive component 60 is a metal component. The outer casing 10 has a first end cap 14, which can also be a metal component. The first end cap 14 is disposed opposite to the partition 20, and a first sub-mounting cavity 12 is located between the first end cap 14 and the partition 20. The partition 20 has a first bearing 15 hole, and the first bearing 15 is disposed in the first bearing 15 hole. The first end cap 14 has a second bearing hole, and the second bearing is disposed in the second bearing hole. The motor shaft 311 passes through the second bearing, with its outer end extending out of the outer casing 10 and its inner end located in the mounting cavity 11, and the inner end of the motor shaft 311 is assembled to the first bearing 15. The conductive component 60 is disposed in the mounting cavity 11, and at least a portion of the conductive component 60 is disposed in the first sub-mounting cavity 12. The conductive component 60 extends along the arrangement direction of the first end cap 14 and the partition 20, and both ends of the conductive component 60 can abut against the partition 20 and the first end cap 14, respectively. Alternatively, the two ends of the conductive element 60 can be riveted to the separator 20 and the first end cap 14 respectively. Further, the conductive element 60 has riveting holes 67 corresponding to the first assembly hole 22. During the injection molding process of the separator 20 and the outer shell 10, a portion of the outer shell 10 is provided in the riveting holes 67 and the corresponding first assembly hole 22 to form an injection-molded riveting structure. Alternatively, the two ends of the conductive element 60 can be bolted to the separator 20 and the first end cap 14 respectively. By providing the conductive element 60, which is connected to both the separator 20 and the first end cap 14, current can flow between the separator 20 and the first end cap 14, thereby balancing the potential between the first bearing 15 and the second bearing, reducing the corrosion risk of the first bearing 15 and the second bearing, and effectively solving the corrosion problem of the first bearing 15 and the second bearing.

[0078] In some embodiments of the present invention, such as Figure 12 and Figure 13 As shown, the separator 20 has a first circumferential limiting portion 23, and the conductive member 60 has a second circumferential limiting portion 61 that is limited and cooperates with the first circumferential limiting portion 23.

[0079] The separator 20 has a first circumferential limiting portion 23, which can be located at the edge of the separator 20, or more specifically, on the side wall of the separator 20. The first circumferential limiting portion 23 can also be located on the surface of the separator 20 facing the second sub-mounting cavity 13. The conductive member 60 has a second circumferential limiting portion 61. The first circumferential limiting portion 23 can be one of a limiting groove and a limiting boss, and the second circumferential limiting portion 61 can be the other of a limiting groove and a limiting boss, with the limiting boss fitted into the limiting groove.

[0080] Alternatively, the first circumferential limiting part 23 can be one of a limiting boss and a limiting flange, and the second circumferential limiting part 61 can be the other of a limiting boss and a limiting flange. For example... Figure 12 , Figure 14 and Figure 17 As shown, this application takes the first circumferential limiting part 23 as a limiting boss and the second circumferential limiting part 61 as a limiting flange as an example. The limiting boss is provided on the side wall of the separator 20. The second circumferential limiting part 61 has two limiting flanges. The two limiting flanges are folded towards the same side of the conductive member 60. The two limiting flanges are opposite to each other and spaced apart to form a limiting gap between the two limiting flanges. When the limiting boss is assembled into the limiting gap, both limiting flanges abut against the limiting boss for limiting.

[0081] When the conductive component 60 and the separator 20 are assembled, the first circumferential limiting part 23 and the second circumferential limiting part 61 are fitted together to limit the assembly, so as to prevent the conductive component 60 and the separator 20 from moving relative to each other along the circumferential direction of the separator 20. During the injection molding process, the shell body 16 of the outer shell 10 and the stator mechanism 32 are fitted together by the first circumferential limiting part 23 and the second circumferential limiting part 61 to reduce the risk of displacement of the conductive component 60, thereby effectively solving the problem of the non-fixed displacement of the conductive component 60.

[0082] In some embodiments of the present invention, such as Figure 12 As shown, the conductive component 60 may include: a first connecting segment 62 and a second connecting segment 63, the first connecting segment 62 and the second connecting segment 63 being bent and connected, the first connecting segment 62 extending in a direction perpendicular to the arrangement direction of the separator 20 and the first end cap 14, the end of the first connecting segment 62 opposite to the second connecting segment 63 being connected to the separator 20, the second connecting segment 63 extending in the arrangement direction of the separator 20 and the first end cap 14, the end of the second connecting segment 63 opposite to the first connecting segment 62 being connected to the first end cap 14.

[0083] Both the first connecting segment 62 and the second connecting segment 63 can be configured as plate-like structures. The first connecting segment 62 and the second connecting segment 63 can be directly connected, indirectly connected, or bent to form an angle. For example, the first connecting segment 62 and the second connecting segment 63 can be perpendicular or approximately perpendicular. The first connecting segment 62 extends in a direction perpendicular to the arrangement direction of the separator 20 and the first end cap 14; alternatively, it can be understood as extending in a direction perpendicular to the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13. The second connecting segment 63 extends in the arrangement direction of the separator 20 and the first end cap 14; in other words, it extends in the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13. The end of the first connecting segment 62 facing away from the second connecting segment 63 is connected to the separator 20, and the end of the second connecting segment 63 facing away from the first connecting segment 62 is connected to the first end cap 14. By setting a first connecting segment 62 and a second connecting segment 63, and bending the first connecting segment 62 and the second connecting segment 63 together, it is convenient for the first connecting segment 62 to be connected to the separator 20, and also convenient for the second connecting segment 63 to be connected to the first end cover 14, thereby reducing the assembly difficulty of the motor 100 and improving the assembly efficiency of the motor 100, thus making the structural design of the conductive component 60 reasonable.

[0084] In some embodiments of the present invention, such as Figure 12 As shown, the conductive element 60 may further include an arc-shaped connecting segment 64, which is connected between the first connecting segment 62 and the second connecting segment 63, so that the first connecting segment 62 and the second connecting segment 63 are bent and connected.

[0085] Among them, the arc-shaped connecting segment 64 can be an arc-shaped structure. The arc-shaped connecting segment 64 is located between the first connecting segment 62 and the second connecting segment 63. One end of the arc-shaped connecting segment 64 is connected to the first connecting segment 62, and the other end of the arc-shaped connecting segment 64 is connected to the second connecting segment 63. The arc-shaped connecting segment 64 has a bending section, thereby achieving the bending connection effect of the first connecting segment 62 and the second connecting segment 63.

[0086] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the motor assembly 30 has a stator mechanism 32, which is located inside the first sub-mounting cavity 12, and the conductive element 60 is located outside the stator mechanism 32.

[0087] The stator mechanism 32 may include a plastic frame and winding coils, with the winding coils disposed within the plastic frame. The stator mechanism 32 is located within the first sub-mounting cavity 12. The plastic frame can be fixedly connected to the outer casing 10; as an example, the plastic frame can be integrally formed with the outer casing 10. The stator mechanism 32 can be a ring structure, sleeved on the outside of the rotor mechanism 31, with the conductive element 60 disposed on the outside of the stator mechanism 32. By disposing of the conductive element 60 on the outside of the stator mechanism 32, the space within the stator mechanism 32 used for mounting the rotor mechanism 31 is avoided, preventing interference between the conductive element 60 and the rotor mechanism 31. This avoids the rotor mechanism 31 becoming stuck due to interference, thus ensuring the normal operation of the motor 100.

[0088] In some embodiments of the present invention, such as Figures 10-12 As shown, the motor 100 may further include: a mounting bracket 70, which is disposed in the first sub-mounting cavity 12 and fixed to the stator mechanism 32, and a conductive element 60 is fixed to the mounting bracket 70.

[0089] The motor 100 may further include a mounting bracket 70, which may be an insulating component, such as a plastic component. The mounting bracket 70 is disposed within the first sub-mounting cavity 12 and is fixed to the stator mechanism 32. The mounting bracket 70 can be snapped onto the stator mechanism 32 or adhered to it. As an example, the mounting bracket 70 is snapped onto the plastic frame of the stator mechanism 32. Further, the mounting bracket 70 is disposed at the end of the plastic frame facing the second sub-mounting cavity 13. The conductive component 60 is fixed to the mounting bracket 70. The conductive component 60 can be adhered to the mounting bracket 70, snapped onto the mounting bracket 70, or fixed to the mounting bracket 70 by bolts. By providing the mounting bracket 70, the mounting bracket 70 fixes the position of the conductive component 60, further reducing the risk of displacement of the conductive component 60, thereby more effectively solving the problem of the conductive component 60's unfixed position displacement.

[0090] In some embodiments of the present invention, such as Figure 16 and Figure 17 As shown, the mounting bracket 70 includes a first mounting bracket body 71 and a second mounting bracket body 72 that are fixedly connected. The first mounting bracket body 71 is fixed to the end of the stator mechanism 32 facing the separator 20. The second mounting bracket body 72 is located outside the stator mechanism 32 and extends along the arrangement direction of the separator 20 and the first end cover 14. The second mounting bracket body 72 is provided with a first fixing structure 721. The conductive member 60 has a second fixing structure 65 that cooperates with the first fixing structure 721.

[0091] The mounting bracket 70 may include a first mounting bracket body 71 and a second mounting bracket body 72. The first mounting bracket body 71 and the second mounting bracket body 72 are fixedly connected, can be snap-fitted together, can be adhesively bonded together, or can be integrally formed. The first mounting bracket body 71 is fixed to the end of the stator mechanism 32 facing the separator 20, or it can be understood as the first mounting bracket body 71 being fixed to the end of the stator mechanism 32 facing the second sub-mounting cavity 13. The second mounting bracket body 72 is located radially outward of the stator mechanism 32, and the second mounting bracket body 72 is an elongated structure. The second mounting bracket body 72 extends along the arrangement direction of the separator 20 and the first end cover 14; in other words, the second mounting bracket body 72 extends along the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13. The second mounting bracket body 72 is provided with a first fixing structure 721, and the conductive component 60 has a second fixing structure 65. By assembling the second fixing structure 65 with the first fixing structure 721, the conductive component 60 can be fixedly mounted on the mounting bracket 70, achieving a fixed connection between the conductive component 60 and the mounting bracket 70. It should be noted that the structures of the first fixing structure 721 and the second fixing structure 65 can be reasonably designed according to actual usage, as long as the second fixing structure 65 assembles with the first fixing structure 721 to fix the conductive component 60 on the mounting bracket 70.

[0092] In some embodiments of the present invention, such as Figure 16 and Figure 17 As shown, the first fixing structure 721 includes one of a fixing boss and a fixing hole, and the second fixing structure 65 includes the other of a fixing boss and a fixing hole, with the fixing boss fitted into the fixing hole.

[0093] The first fixing structure 721 can be configured as either a fixing boss or a fixing hole, and the second fixing structure 65 can be configured as the other of the fixing boss and fixing hole. When the first fixing structure 721 is configured as a fixing boss, the second fixing structure 65 is configured as a fixing hole, and vice versa. This application uses the example of the first fixing structure 721 being configured as a fixing boss and the second fixing structure 65 being configured as a fixing hole for explanation. The fixing boss is assembled into the fixing hole, and the fixing boss can pass through the fixing hole. When the fixing boss is assembled into the fixing hole, the fixing boss and the second mounting bracket body 72 are interference-fitted, thereby fixing the conductive element 60 to the mounting bracket 70. Furthermore, by providing the fixing boss and the fixing hole, the structure of the first fixing structure 721 and the second fixing structure 65 can be simplified, making it easier to process the first fixing structure 721 and the second fixing structure 65, and thus improving the production efficiency of the motor 100.

[0094] In some embodiments of the present invention, such as Figure 16 and Figure 17 As shown, the first fixing structure 721 includes a first snap-fit ​​block 7211 and a second snap-fit ​​block 7212. The first snap-fit ​​block 7211 and the second snap-fit ​​block 7212 are opposite to each other and spaced apart to form an assembly space 7213 between the first snap-fit ​​block 7211 and the second snap-fit ​​block 7212. The conductive element 60 passes through the assembly space 7213 and has a snap-fit ​​interface 66 on both sides of the conductive element 60 along the arrangement direction of the first snap-fit ​​block 7211 and the second snap-fit ​​block 7212. The first snap-fit ​​block 7211 and the second snap-fit ​​block 7212 are respectively snapped into the corresponding snap-fit ​​interface 66.

[0095] The first fixing structure 721 includes a first snap-fit ​​block 7211 and a second snap-fit ​​block 7212. The first snap-fit ​​block 7211 and the second snap-fit ​​block 7212 are opposite to each other and spaced apart along the width direction of the second mounting bracket body 72, thereby forming an assembly space 7213 between the first snap-fit ​​block 7211 and the second snap-fit ​​block 7212. The width direction of the second mounting bracket body 72 is perpendicular to the extension direction of the second mounting bracket body 72. The conductive component 60 passes through the assembly space 7213. The second fixing structure 65 includes a locking interface 66, which may include two locking interfaces 66. Along the arrangement direction of the first locking block 7211 and the second locking block 7212, both sides of the conductive component 60 have locking interfaces 66. The locking interfaces 66 on both sides of the conductive component 60 are respectively arranged corresponding to the first locking block 7211 and the second locking block 7212. The first locking block 7211 and the second locking block 7212 are respectively locked into the corresponding locking interfaces 66 on both sides of the conductive component 60, thereby fixing the conductive component 60 to the mounting bracket 70. Furthermore, by setting the locking interface 66, the first locking block 7211 and the second locking block 7212, the structure of the first fixing structure 721 and the second fixing structure 65 can be simplified, making it easier to process the first fixing structure 721 and the second fixing structure 65, and improving the production efficiency of the motor 100.

[0096] Furthermore, there are multiple first fixing structures 721 and multiple second fixing structures 65. The multiple first fixing structures 721 are arranged along the extending direction of the second mounting bracket body 72, and the multiple second fixing structures 65 are arranged along the extending direction of the second mounting bracket body 72. The multiple first fixing structures 721 and multiple second fixing structures 65 are assembled in a one-to-one correspondence. By providing multiple first fixing structures 721 and multiple second fixing structures 65, the assembly firmness between the conductive component 60 and the mounting bracket 70 can be improved, allowing the conductive component 60 to be more securely mounted on the mounting bracket 70.

[0097] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the outer casing 10 may include: a casing body 16 and a second end cap 17, the casing body 16 and the second end cap 17 being fixedly connected to jointly define the mounting cavity 11, and the partition 20 being fixedly connected to the casing body 16.

[0098] The outer casing 10 may include a casing body 16 and a second end cap 17. The casing body 16 may be the casing 10 of the motor assembly 30. The casing body 16 includes a first end cap 14. The casing body 16 and the second end cap 17 may be arranged opposite each other along the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13. The casing body 16 and the second end cap 17 may be fixedly connected by bolts or snap-fitted together. The casing body 16 defines a first space open toward the second end cap 17, and the second end cap 17 defines a second space open toward the casing body 16. The first space and the second space are constructed as a mounting cavity 11. After the casing body 16 and the second end cap 17 are fixedly assembled, the casing body 16 and the second end cap 17 together define the mounting cavity 11, thereby realizing the setting of the mounting cavity 11. The partition 20 can be set in the first space. The partition 20 can be integrally formed with the shell body 16. By fixing the partition 20 to the shell body 16, the second end cover 17 and the shell body 16 can be assembled to realize the arrangement of the second sub-mounting cavity 13.

[0099] In some embodiments of the present invention, such as Figure 2 , Figure 6 and Figure 7 As shown, the second end cover 17 has an end wall 171 opposite to the separator 20. The side of the end wall 171 facing the separator 20 is provided with a first mounting platform 172 and a second mounting platform 173. The height of the first mounting platform 172 protruding from the end wall 171 is less than the height of the second mounting platform 173 protruding from the end wall 171. The electronic control board 40 is located inside the second end cover 17 and fixed to the first mounting platform 172. The second mounting platform 173 is used to install the ground wire 91.

[0100] Along the arrangement direction of the first sub-mounting cavity 12 and the second sub-mounting cavity 13, the second end cover 17 has an end wall 171 opposite to the partition 20, and the second sub-mounting cavity 13 is located between the partition 20 and the end wall 171. A first mounting platform 172 and a second mounting platform 173 are provided on the side of the end wall 171 facing the partition 20. The first mounting platform 172 and the second mounting platform 173 can be spaced apart. The height of the first mounting platform 172 protruding from the end wall 171 is less than the height of the second mounting platform 173 protruding from the end wall 171, that is, the setting height of the first mounting platform 172 and the setting height of the second mounting platform 173 are different. The end faces of the first mounting platform 172 and the second mounting platform 173 facing the partition 20 are arranged in layers. The electrical control board 40 is located in the second space of the second end cover 17, and the electrical control board 40 can be fixed to the first mounting platform 172 by bolts. The AC power cord 90 passes through the second end cap 17 and one end extends into the first sub-mounting cavity 12. The AC power cord 90 is connected to the control board 40. The second mounting platform 173 is used to install the ground wire 91 of the AC power cord 90. The connection end of the ground wire 91 is installed on the second mounting platform 173 by screws, which helps to reduce the installation distance of the screws for tightening the ground wire 91 and solves the problem of inconvenient installation due to the non-magnetic screws for installing the ground wire 91.

[0101] In some embodiments of the present invention, such as Figure 2 , Figure 6 and Figure 7 As shown, the end wall 171 may be provided with a heat dissipation structure 174, which is in contact with the driver chip of the electronic control board 40.

[0102] The end wall 171 may be equipped with a heat dissipation structure 174, which abuts against the driver chip of the electronic control board 40. The heat dissipation structure 174 can be a heat dissipation reinforcing rib structure or a heat dissipation adhesive. The type of heat dissipation structure 174 can be reasonably selected and designed according to the actual situation, as long as the heat dissipation structure 174 can play a heat dissipation role. The heat dissipation structure 174 can be a heat dissipation metal block, a thermally conductive silicone sheet, a thermally conductive adhesive, etc. The heat dissipation structure 174 can dissipate heat from the driver chip of the electronic control board 40, cool the driver chip of the electronic control board 40, reduce the temperature rise of the driver chip, and conduct the heat generated by the driver chip to the second end cover 17 for dissipation, thereby extending the service life of the driver chip and improving the working efficiency of the motor 100.

[0103] In some embodiments of the present invention, such as Figure 3 and Figure 7 As shown, the second end cap 17 has a first positioning structure 175, and the shell body 16 has a second positioning structure 161 that positions and cooperates with the first positioning structure 175.

[0104] The first positioning structure 175 can be disposed on the end wall 171 of the second end cover 17, and the second positioning structure 161 can be disposed on the end face of the shell body 16 facing the second end cover 17. As an example, a third mounting platform is provided on the side of the end wall 171 facing the separator 20, and the first positioning structure 175 is provided on the end face of the third mounting platform facing the separator 20. The first positioning structure 175 is one of a positioning post and a positioning hole, and the second positioning structure 161 is the other of a positioning post and a positioning hole. This application uses the example of the first positioning structure 175 being a positioning post and the second positioning structure 161 being a positioning hole for explanation. When the second end cover 17 and the shell body 16 are assembled, the positioning post is installed in the positioning hole, which can play a circumferential limiting role, preventing the second end cover 17 from rotating relative to the shell body 16, and can also play a foolproof role, preventing the second end cover 17 and the shell body 16 from being misaligned, which is beneficial to improving the assembly efficiency of the second end cover 17 and the shell body 16.

[0105] In some embodiments of the present invention, the motor 100 may include a sealing ring, the second end cover 17 may have a mounting groove, a portion of the sealing ring is installed in the mounting groove, the sealing ring is pressed and fixed in the mounting groove, after the second end cover 17 and the shell body 16 are assembled, the sealing ring can seal the gap between the second end cover 17 and the shell body 16, and play a role in sealing and waterproofing.

[0106] In some embodiments of the present invention, such as Figure 11 and Figure 16 As shown, the first mounting bracket body 71 has a slot 711, and the conductive component 60 is mounted in the slot 711 and passes through the slot 711. As an example, the arc-shaped connecting section 64 passes through the slot 711. The conductive component 60 can be limited and engaged with the side wall of the slot 711, further preventing relative movement between the conductive component 60 and the separator 20 along the circumferential direction of the separator 20. During the injection molding process, the shell body 16 of the outer casing 10 and the stator mechanism 32 further reduce the risk of displacement of the conductive component 60, thereby more effectively solving the problem of the non-fixed displacement of the conductive component 60.

[0107] In some embodiments of the present invention, such as Figure 11 and Figure 17As shown, the end of the second connecting segment 63 facing away from the first connecting segment 62 has a bent portion 68. The bent portion 68 bends toward the second mounting bracket body 72. The bent portion 68 includes a third connecting segment 681 and a fourth connecting segment 682. The third connecting segment 681 is connected between the second connecting segment 63 and the fourth connecting segment 682. The second connecting segment 63 and the fourth connecting segment 682 are opposite to each other and spaced apart. The bent portion 68 and the second connecting segment 63 together define the assembly groove 683. The end of the second mounting bracket body 72 facing away from the first mounting bracket body 71 is installed in the assembly groove 683. The second mounting bracket body 72 abuts and limits the bending portion 68 and the second connecting segment 63, thereby making the assembly of the conductive component 60 and the mounting bracket 70 more secure.

[0108] An air conditioner according to a second aspect of the present invention includes: the motor 100 in the above embodiment.

[0109] According to the air conditioner of the present application embodiment, the motor 100 in the above embodiment can separate the motor assembly 30 and the electrical connector 50, which can prevent the rotor mechanism 31 of the motor assembly 30 and the electrical connector 50 from rubbing together, effectively solving the problem of damage to the electrical connector 50. In addition, it can prevent welding slag generated during the welding process of the electrical connector 50 from falling into the first sub-mounting cavity 12, reducing the risk of the motor 100 getting stuck and damaged due to welding slag falling into the first sub-mounting cavity 12, thereby improving the working performance of the air conditioner.
