Therefore, other examples of the exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0047] In some embodiments, as Figure 1 and Figure 2As shown, the stator module includes: a stator body 10, an armature winding 20, a power supply assembly 30, a first cover member 40, a first waterproof structure, a second waterproof structure, and a third waterproof structure. The stator body 10 has a housing cavity 11 with a side opening 12. The first end of the armature winding 20 is connected to the stator body 10, and the second end of the armature winding 20 extends outside the stator body 10. The power supply assembly 30 is disposed within the housing cavity 11 and electrically connected to the armature winding 20 through the side opening 12. The first cover member 40 is located on a first side of the stator body 10 and a first side of the armature winding 20, and together with the stator body 10, encloses the housing cavity 11. The first waterproof structure is disposed between the first cover member 40 and the stator body 10. A first housing cavity 61 is provided on the first cover member 40 and / or the stator body 10, and the first waterproof structure is disposed within the first housing cavity 61. The second waterproof structure is disposed at the joint between the first cover member 40 and the armature winding 20. The third waterproof structure is provided at a joint between the stator body 10 and the first cover member 40 and connects the first waterproof structure and the second waterproof structure.

[0048] In this way, the provision of the side opening 12 facilitates the wiring operation between the armature winding 20 and the power supply assembly 30 in the accommodating cavity 11. The provision of the first waterproof structure can seal the joint between the first cover member 40 and the stator body 10 to prevent water from entering the accommodating cavity 11 from between the first cover member 40 and the stator body 10. In addition, the first accommodating cavity 61 facilitates the provision of the first waterproof structure and can also play a role in positioning the first waterproof structure, making the provision position of the first waterproof structure more accurate and the waterproof effect more reliable. The provision of the second waterproof structure can seal the joint between the first cover member 40 and the armature winding 20 to prevent water from entering the accommodating cavity 11 from the joint between the first cover member 40 and the armature winding 20. The provision of the third waterproof structure can seal the joint between the stator body 10 and the first cover member 40 to prevent water from entering the accommodating cavity 11 from the joint between the stator body 10 and the first cover member 40. Furthermore, the third waterproof structure connects the first and second waterproof structures, allowing the first, second, and third waterproof structures to be interconnected. This reduces the occurrence of isolated ends of the waterproof structure, forming a more complete waterproof barrier and reducing water ingress caused by processing errors and other factors. It also makes the arrangement of the waterproof structure more consistent and smooth, facilitating uniform placement of the waterproof structure, further improving the sealing performance of the waterproof structure, and thus reducing the probability of water entering the accommodating cavity 11. The provision of the first, second, and third waterproof structures effectively blocks water vapor or liquid from entering through the joints between the first cover member 40 and the stator body 10, the joints between the armature winding 20 and the first cover member 40, and the joints between the stator body 10 and the first cover member 40. This provides waterproofing for electronic components such as the power supply assembly 30 within the accommodating cavity 11, making it difficult for water vapor or liquid to enter the stator module, thereby ensuring the normal operation of electronic components such as the power supply assembly 30. Therefore, the technical solution of the present application effectively solves the problem in the related art that water vapor or liquid easily enters the stator module, thereby affecting the normal use of electronic components in the stator module.

[0049] In some embodiments, the first waterproof structure, the second waterproof structure, the third waterproof structure, and the fourth waterproof structure are preferably adhesive layers, colloids, or flexible sealing strips.

[0050] In some embodiments, as Figure 2 、 Figure 4 and Figure 5As shown, the first cover member 40 includes a main body 41 and a contact portion 42 facing the armature winding 20. The contact portion 42 is arranged in contact with both the armature winding 20 and the stator body 10. At least a portion of the contact portion 42 and the stator body together enclose a housing cavity 11. The outer peripheral surface 421 of the contact portion 42 abuts the stator body, the armature winding, and the main body. The surface of the armature winding 20 facing the main body 41, at least a portion of the outer peripheral surface 421, and the surface of the main body 41 facing the armature winding 20 together enclose a second housing cavity 62. The second waterproof structure is in contact with the cavity wall of the second housing cavity 62. The provision of the contact portion 42 can reduce the gap between the first cover member 40 and the armature winding 20, as well as the gap between the first cover member 40 and the stator body 10, thereby facilitating the provision of the second waterproof structure and improving the sealing performance of the second waterproof structure. The provision of the contact portion 42 also facilitates the processing of the second housing cavity 62. The second accommodating cavity 62 facilitates the installation of the second waterproof structure and can also play a role in positioning the second waterproof structure, so that the installation position of the second waterproof structure is more accurate and the waterproof sealing effect is more reliable.

[0051] In some embodiments, as Figure 4 and Figure 6 As shown, a third accommodating cavity 63 is formed between the main body 41, at least a portion of the outer circumferential surface 421, and the stator body 10. The third accommodating cavity 63 communicates with the second accommodating cavity 62 and the first accommodating cavity 61, and the third waterproof structure is in contact with the cavity wall of the third accommodating cavity 63. The first side of the stator body 10 protrudes from the first side of the armature winding 20, which can increase the volume of the accommodating cavity 11 and facilitate the installation of the power supply assembly 30 within the accommodating cavity 11 and the connection operation with the armature winding 20. The third accommodating cavity 63 facilitates the installation of the third waterproof structure and also serves to position the third waterproof structure, making the installation position of the third waterproof structure more accurate and the waterproof sealing effect more reliable. In addition, the third accommodating cavity 63 and the third waterproof structure are arranged between the main body 41 and the stator body 10, so that the joint between the first cover member 40 and the stator body 10 can be sealed, and the third accommodating cavity 63 can be communicated with the first accommodating cavity 61 and the second accommodating cavity 62, so that the third waterproof structure can be connected with the first waterproof structure and the second waterproof structure, reducing the appearance of isolated ends of the waterproof structure, forming a more complete waterproof barrier, and reducing the problem of water ingress caused by processing errors and other reasons at the isolated ends, and making the setting of the waterproof structure more coherent and smooth, facilitating the uniform setting of the waterproof structure, further improving the sealing performance of the waterproof structure, and thus reducing the probability of water entering the accommodating cavity 11.

[0052] In some embodiments, as Figure 4 、 Figure 5 as well as Figure 6As shown, the body 41 includes a connected cover plate 411 and a protruding plate 412. The protruding plate 412 is protruding from the surface of the cover plate 411 near the armature winding 20. The protruding plate 412 has a first surface 4121 facing the armature winding 20 and a second surface 4122 facing the stator body 10. The contact portion 42 is provided on the first surface 4121 and the second surface 4122. The second surface 4122, at least a portion of the outer peripheral surface 421, and the surface of the stator body 10 facing the protruding plate 412 collectively enclose a third accommodating cavity 63. The provision of the protruding plate 412 can facilitate reducing the gap between the cover plate 411 and the armature winding 20, as well as the gap between the first cover member 40 and the stator body 10, thereby facilitating the installation of the second waterproof structure and improving the sealing performance of the second waterproof structure. Furthermore, the provision of the protruding plate 412 facilitates the processing of the contact portion 42. The formation of the third accommodating cavity 63 is simple, facilitating its processing. The third accommodating cavity 63 is composed of the second surface 4122 , at least part of the outer peripheral surface of the contact portion 42 and the surface of the stator body 10 facing the protruding plate 412 , so that the third waterproof structure can more reliably seal the contact portion 42 and the stator body 10 .

[0053] In some embodiments, as Figure 4 and Figure 5 As shown, the first accommodating cavity 61 extends through the surface of the stator body 10 facing the contact portion 42, thereby communicating with the third accommodating cavity 63. The communication between the first accommodating cavity 61 and the third accommodating cavity 63 ensures seamless connection between the first waterproof structure and the third waterproof structure between the first cover member 40 and the stator body 10, forming a more complete waterproof barrier and reducing potential leakage points.

[0054] In some embodiments, as Figure 2 、 Figure 4 as well as Figure 5 As shown, one of the stator body 10 and the first cover member 40 defines a first accommodating cavity 61, and the other of the stator body 10 and the first cover member 40 is provided with a first rib 43, which extends into the first accommodating cavity 61. The first waterproof structure is disposed against the first rib 43 and the wall of the first accommodating cavity 61. The arrangement of the first rib 43 and the first accommodating cavity 61 enables the first rib 43 to squeeze the first waterproof structure within the first accommodating cavity 61 when the first cover member 40 is disposed on the stator body 10, ensuring that the first waterproof structure fills the gap between the first accommodating cavity 61 and the first rib 43. This further seals the gap between the first cover member 40 and the stator body 10, improves the reliability of the first waterproof structure, and also enhances the sealing performance between the first cover member 40 and the stator body 10.

[0055] In some embodiments, the first accommodating cavity 61 includes a first slot segment, a second slot segment, and a third slot segment. The first slot segment and the second slot segment are respectively arranged on either side of the accommodating cavity 11, and the third slot segment is connected between the first slot segment and the second slot segment. The first slot segment extends through the surface of the stator body 10 facing the convex plate 412, and the second slot segment extends through the surface of the stator body 10 facing the convex plate 412. The first rib 43 includes a first protruding segment, a second protruding segment, and a third protruding segment. The first protruding segment and the second protruding segment are respectively arranged on either side of the accommodating cavity 11, and the third protruding segment is connected between the first protruding segment and the second protruding segment. The first protruding segment extends into the first slot segment, the second protruding segment extends into the second slot segment, and the third protruding segment extends into the third slot segment. The third slot segment is in the shape of a broken line, a curve, or a straight line to adapt to the shape of the accommodating cavity 11.

[0056] In some embodiments, as Figures 2 to 5 As shown, the length of the first rib 43 is less than the depth of the first accommodating cavity 61. This allows the first waterproof structure to be arranged around three sides of the first rib 43, allowing it to more fully fill the space between the first rib 43 and the first accommodating cavity 61. This avoids physical restrictions on the first waterproof structure and prevents excessive squeezing of the first waterproof structure, thereby improving the reliability and service life of the first waterproof structure and further enhancing the sealing effect.

[0057] It should be noted that the length of the first rib 43 refers to the distance that the first rib 43 protrudes toward the bottom wall of the first accommodating cavity 61 .

[0058] In some embodiments, as Figures 2 to 4 As shown, the stator module also includes a fourth waterproof structure, which is provided at the joint between the stator body 10 and the second side of the armature winding 20. The fourth waterproof structure can seal the gap between the second side of the armature winding 20 and the stator body 10, preventing water from entering the accommodating cavity 11 from the second side of the armature winding 20, thereby providing a waterproof effect on both sides of the armature winding 20.

[0059] In some embodiments, as Figures 2 to 4 as well as Figure 6As shown, the stator body 10 has a third surface 13 arranged opposite to the second side of the armature winding 20. The third surface 13 is provided with a first boss 71. The first boss 71 is used to abut against the armature winding 20. Part of the third surface 13, at least part of the first boss 71 and the surface of the second side of the armature winding 20 are surrounded to form a fourth accommodating cavity 64, and the fourth waterproof structure is arranged in the fourth accommodating cavity 64. The fourth accommodating cavity 64 facilitates the arrangement of the fourth waterproof structure and can also play a role in positioning the fourth waterproof structure, making the arrangement position of the fourth waterproof structure more accurate and the waterproof effect more reliable. The arrangement of the first boss 71 facilitates the formation and processing of the fourth accommodating cavity 64, reduces the processing cost of the stator module, and effectively improves the sealing performance of the stator module.

[0060] It should be noted that the third outer peripheral surface of the stator body 10 refers to the surface of the stator body 10 along the outer side of its own circumferential direction.

[0061] In some embodiments, as Figures 2 to 4 As shown, the stator body 10 is provided with a fifth accommodating cavity 65, which extends along the thickness direction of the armature winding 20. The fifth accommodating cavity 65 connects the fourth accommodating cavity 64 and the second accommodating cavity 62. The stator module also includes a fifth waterproof structure disposed within the fifth accommodating cavity 65. The first end of the fifth waterproof structure is connected to the fourth waterproof structure, and the second end of the fifth waterproof structure is connected to the second waterproof structure and the third waterproof structure. The fifth waterproof structure is in contact with the armature winding 20. The fifth accommodating cavity 65 facilitates the installation of the fifth waterproof structure and can also play a role in positioning the fifth waterproof structure, making the installation position of the fifth waterproof structure more accurate and the waterproof effect more reliable. The use of the fifth accommodating cavity 65 and the fifth waterproof structure enables a waterproof connection between the first side and the second side of the armature winding 20, forming a closed waterproof structure, further enhancing the waterproof capability of the entire stator module.

[0062] In some other embodiments, the second end of the fifth waterproof structure is connected to the second waterproof structure or the third waterproof structure, so as to facilitate the processing operation of the receiving groove while forming a complete waterproof barrier.

[0063] In some embodiments, as Figure 6As shown, the stator body 10 has a fourth surface 14 positioned opposite the end face of the first end of the armature winding 20. A second boss 72 is projecting from the fourth surface 14, which is configured to abut against the armature winding 20. A portion of the fourth surface 14, at least a portion of the second boss 72, and the end face of the first end of the armature winding 20 enclose a fifth accommodating cavity 65. The provision of the second boss 72 facilitates the formation and processing of the fifth accommodating cavity 65, reducing the processing cost of the stator module and effectively improving the sealing performance of the stator module. The provision of the second boss 72 ensures the accurate installation position of the fifth waterproof structure, thereby providing a more effective waterproof barrier.

[0064] In some embodiments, as Figure 1 and Figure 2 As shown, the second end of the armature winding 20 extends in a straight line or an arc. This allows the stator module to drive the mover module to move in a straight line or an arc to adapt to different stator module structural layouts, thereby improving the versatility and adaptability of the stator module.

[0065] In other embodiments, the armature winding 20 is arranged horizontally, with the second end of the armature winding 20 forming a delivery end, which extends in a straight line or along an arc. This allows the stator module to drive the mover module to move in a straight line or along an arc when the stator module is horizontal, adapting to different stator module layouts and improving the versatility and adaptability of the stator module.

[0066] It should be noted that the first side of the stator body 10 refers to the side of the stator body 10 facing the first cover member 40. The second side of the stator body 10 refers to the side of the stator body 10 facing away from the first cover member 40. The first side of the armature winding 20 refers to the side of the armature winding 20 facing the first cover member 40. The second side of the armature winding 20 refers to the side of the armature winding 20 facing away from the first cover member 40.

[0067] In some embodiments, as Figures 7 to 9As shown, the stator module also includes a position detection member, a positioning member 90 and a second cover member 80. The second cover member 80 is located on the second side of the stator body 10, and a first positioning groove 81 is provided on the second cover member 80. The positioning member 90 is arranged in the first positioning groove 81 and is positioned and matched with the first positioning groove 81. A second positioning groove 91 is provided on the surface of the positioning member 90 facing the bottom of the first positioning groove 81. The groove wall of the second positioning groove 91 and the groove bottom of the first positioning groove 81 form an installation cavity 100, and the position detection member is arranged in the installation cavity 100. In this way, arranging the position detection member in the second positioning groove 91 can improve the positioning accuracy of the position detection member on the positioning member 90. The positioning member 90 is arranged in the first positioning groove 81, and the first positioning groove 81 positions the positioning member 90 to improve the positioning accuracy of the positioning member 90 on the second cover member 80. This improves the positioning accuracy of the position detection member on the second cover member 80, so as to improve the position detection accuracy of the stator module by the position detection member. Furthermore, by providing the mounting cavity 100 , the position detecting element can be better isolated from the external environment, reducing the possibility of water contacting the position detecting element, thereby improving the reliability and service life of the position detecting element.

[0068] In some embodiments, a first connection hole is provided on the armature winding 20, and a second connection hole is provided on the stator body 10. A screw is passed through the second cover member 80, the first connection hole on the armature winding 20, and the second connection hole on the stator body 10, and the end of the screw facing away from the screw head is connected to the protruding plate 412 to secure the armature winding 20 to the stator body 10. Waterproof glue is applied to the screw head to prevent water from entering the accommodating cavity 11 through the screw head.

[0069] In some embodiments, as Figure 7 and Figure 9 As shown, the stator module also includes a sixth waterproof structure disposed between the second cover member 80 and the stator body 10. A sixth accommodating cavity 66 is provided between the positioning member 90 and the side wall of the first positioning groove 81, and the sixth waterproof structure is disposed within the sixth accommodating cavity 66. The sixth accommodating cavity 66 facilitates the installation of the sixth waterproof structure and can also serve to position the sixth waterproof structure, making the installation position of the sixth waterproof structure more accurate and the waterproof effect more reliable. In addition, the sixth waterproof structure provides a waterproof barrier at the connection between the second cover member 80 and the stator body 10, improving the sealing performance between the second cover member 80 and the stator body 10, further improving the waterproof performance of the stator module, and ensuring the stable operation of the position detection member and the power supply assembly 30.

[0070] In some embodiments, as Figure 7 and Figure 9As shown, a second rib 15 is provided on the surface of the second side of the stator body 10. The second rib 15 extends into the sixth accommodating cavity 66, and the sixth waterproof structure is disposed between the sixth accommodating cavity 66 and the second rib 15. The arrangement of the second rib 15 and the sixth accommodating cavity 66 enables, when the second cover member 80 is placed on the stator body 10, the second rib 15 to squeeze the sixth waterproof structure within the sixth accommodating cavity 66, ensuring that the sixth waterproof structure fills the space between the sixth accommodating cavity 66 and the second rib 15. This further seals the gap between the second cover member 80 and the stator body 10, improving the reliability of the sixth waterproof structure and enhancing the sealing performance between the second cover member 80 and the stator body 10.

[0071] In some embodiments, as Figures 7 to 9 As shown, a third boss 73 is provided on the surface of the positioning member 90 facing away from the mounting cavity 100. A portion of the surface of the positioning member 90 facing away from the mounting cavity 100, at least a portion of the third boss 73, and the sidewalls of the first positioning groove 81 enclose a sixth accommodating cavity 66. The sixth accommodating cavity 66 is circumferentially disposed outside the mounting cavity 100. The provision of the third boss 73 facilitates the formation and processing of the sixth accommodating cavity 66, reduces the processing cost of the stator module, and effectively improves the sealing performance of the stator module.

[0072] In some embodiments, as Figure 7 As shown, the stator body 10 is provided with a first wire hole 16 that connects the second side of the armature winding 20 with the accommodating cavity 11, and the positioning member 90 is provided with a second wire hole 92 that connects the mounting cavity 100 with the second side of the armature winding 20. The design of the first wire hole 16 and the second wire hole 92 facilitates the connection and routing of the position detection component in the mounting cavity 100 and the power supply assembly 30 in the accommodating cavity 11, facilitating wiring operations within the stator module and facilitating processing and installation.

[0073] In some embodiments, as Figure 1 and Figure 5 As shown, the stator module also includes a waterproof electrical connector 110 provided on the stator body 10, which is electrically connected to the power supply assembly 30.
