[0024] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] The motor according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 14 As shown, the motor according to the embodiment of the present invention includes: a coil assembly, a gear assembly 500 , a first cover plate 60 and a second cover plate 70 .

[0027] Specifically, the coil assembly includes a pin 200 and a motor frame, and the motor frame includes a first winding portion 10, a first flange portion 20, a second flange portion 30, a mounting portion 40 and a blocking portion 50. The first winding portion 10 is columnar in shape and is used to wind the winding wire. The first flange portion 20 is arranged at one axial end of the first winding portion 10, and the second flange portion 30 is arranged at the other axial end of the first winding portion 10. The mounting portion 40 is arranged on the outer periphery of the first flange portion 20. The mounting portion 40 is provided with a first through hole 41, and the first through hole 41 is used to install the pin 200. The blocking portion 50 protrudes far from the mounting portion 40. The surface of one side of the second flange 30 is located on the side of the first through hole 41 close to the axis of the first winding part 10, at least a part of the gear assembly 500 is located on one side of the blocking part 50, and the pin 200 is located on the other side of the blocking part 50. The blocking part 50 can prevent the metal beads generated by the metal treatment of the pin 200 from rolling to the gear assembly 500. At least a part of the first cover plate 60 is arranged on the side of the mounting part 40 away from the axis of the first winding part 10, and the first cover plate 60 is provided with a second through hole 61. One end of the pin 200 passes through the second through hole 61 and is connected to the lead 400. Figure 1 As shown, the second cover plate 70 is disposed on a side of the first cover plate 60 away from the mounting portion 40 , and the second cover plate 70 can shield the lead wire 400 and the connection portion between the lead wire 400 and the plug pin 200 .

[0028] In other words, the motor according to the embodiment of the present invention adopts a combination of a coil assembly, a gear assembly 500, a first cover plate 60 and a second cover plate 70, the coil assembly mainly includes a pin 200 and a motor frame, and the motor frame mainly includes a first winding part 10, a first flange part 20, a second flange part 30, a mounting part 40 and a blocking part 50.

[0029] The first winding part 10 is cylindrical in shape, for example, the first winding part 10 is a cylindrical part extending in the up-down direction. The first winding part 10 can be used to wind the winding wire, that is, the winding wire can be wound on the first winding part 10. The axis of the first winding part 10 is Figure 3 As shown by the dotted line in .

[0030] The first flange 20 is provided at one end of the first winding part 10 in the axial direction, and the second flange 30 is provided at the other end of the first winding part 10 in the axial direction. For example, the first flange 20 is provided at the upper end of the first winding part 10, and the second flange 30 is provided at the lower end of the first winding part 10. The mounting portion 40 is provided at the outer periphery of the first flange 20. For example, the mounting portion 40 is provided at a position of approximately one-fourth of the outer periphery of the first flange 20. At least one first through hole 41 is provided on the mounting portion 40, that is, a through first through hole 41 is provided. The first through hole 41 can be used to install the plug pin 200, that is, the plug pin 200 can be installed in the first through hole 41, and the winding wire can be connected to the plug pin 200 during installation. In this embodiment, the shape of the cross section of the plug pin 200 is not limited. For example, the cross section of the plug pin 200 is square, which can prevent the winding wire from sliding. That is, the plug pin 200 includes but is not limited to a square. In addition, during installation, the winding wire on the first winding portion 10 can first pass through the open groove 48 and then be wound around the pin 200 .

[0031] Moreover, the blocking portion 50 protrudes from the surface of the mounting portion 40 on the side away from the second collar portion 30, and the blocking portion 50 is located on the side of the first through hole 41 close to the axis of the first winding portion 10. For example, the first collar portion 20 is located above the second collar portion 30, and the blocking portion 50 is located on the upper surface of the mounting portion 40.

[0032] And, if Figure 2As shown, at least a portion of the gear assembly 500 is located on one side of the blocking portion 50. For example, the gear assembly 500 includes a plurality of gears meshing with each other, and at least a portion of the gears are located on one side of the blocking portion 50. The plug pin 200 is located on the other side of the blocking portion 50. The blocking portion 50 can prevent the metal beads generated when the plug pin 200 is metal-treated from rolling to the gear assembly 500. For example, when the plug pin 200 is tinned, the solder beads after soldering can be prevented from entering the interior of the gear assembly 500, causing jamming or even jamming. In other words, the solder beads generated by the tinning of the terminal of the existing motor can be prevented from splashing into the interior of the gear box. In addition, during assembly, the plug pin 200 can be tinned after winding the enameled wire, which can play a protective function. The enameled wire connector is wrapped around the plug pin 200, and the plug pin 200 and the enameled wire can be connected to each other through tinning.

[0033] In addition, at least a portion of the first cover plate 60 is disposed on a side of the mounting portion 40 away from the axis of the first winding portion 10, that is, the first cover plate 60 can cover the outside of the mounting portion 40, for example, on a projection plane extending in the vertical direction with a height and a width in the horizontal direction, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It can be understood that, in this embodiment, the side close to the axis direction of the first winding portion 10 is the inner side, and the side away from the axis direction of the first winding portion 10 is the outer side. The first cover plate 60 is provided with a second through hole 61, and one end of the plug pin 200 is connected to the lead wire 400 after passing through the second through hole 61, that is, a portion of the plug pin 200 extends out of the first through hole 41 and then extends into the second through hole 61, and then passes through the second through hole 61 and is connected to the lead wire 400. In this embodiment, the first cover plate 60 can be used to shield the mounting portion 40, and the plug pins 200 and winding wires extending out of the mounting portion 40 can also be shielded, which can improve the appearance and safety, and the plug pins 200 can be limited by the second through hole 61. In addition, by providing the second through hole 61 on the first cover plate 60, one end of the plug pin 200 passes through the second through hole 61 and is connected to the lead wire 400. For example, one end of the plug pin 200 passes through the second through hole 61 and is welded to the lead wire 400. Under the shielding of the first cover plate 60, the metal material during welding is not easy to splash into the inner side of the gear assembly 500.

[0034] The second cover plate 70 is disposed on a side of the first cover plate 60 away from the mounting portion 40, that is, the second cover plate 70 is disposed on the outside of the first cover plate 60. For example, on a projection plane extending in the vertical direction and in the horizontal direction, the orthographic projection of the second cover plate 70 covers the orthographic projection of the first cover plate 60. In this embodiment, the second cover plate 70 can shield the lead wire 400 and the connection portion between the lead wire 400 and the plug pin 200, thereby improving the aesthetics, structural stability and safety, and preventing the connection portion between the lead wire 400 and the plug pin 200 and the lead wire 400 from being affected by the external environment.

[0035] Therefore, the motor according to the embodiment of the present invention adopts a combination of a coil assembly, a gear assembly 500, a first cover plate 60 and a second cover plate 70. Not only can the blocking portion 50 be used to block the metal beads generated during the metal treatment of the pin 200 from rolling to the gear assembly 500, but it can also effectively prevent the gear assembly 500 from being affected by the metal beads, such as causing the motor to get stuck or jammed; the first cover plate 60 and the second cover plate 70 can also be used to improve the aesthetics, structural stability and safety.

[0036] According to an embodiment of the present invention, in a direction parallel to the axis of the first winding portion 10, the highest end of the plug pin 200 is higher than the highest end of the blocking portion 50. For example, in the up-down direction, the highest end of the plug pin 200 installed in the first through hole 41 is higher than the highest end of the blocking portion 50. During the installation process, a force can be applied from the inner side of the installation portion 40 through the blocking portion 50 to the upper end of the plug pin 200, driving the upper end of the plug pin 200 to bend outward. In this embodiment, by limiting the position of the highest end of the plug pin 200, during the installation process, a force can be applied to the upper part of the plug pin 200 installed in the first through hole 41 through the blocking portion 50 in a direction from the inside to the outside, driving the upper part of the plug pin 200 to bend outward.

[0037] In some specific embodiments of the present invention, Figure 3 As shown, in the axial direction from the mounting portion 40 to the first winding portion 10, the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49. That is, along a direction from the outside to the inside, the first through hole 41, the gap 49 and the blocking portion 50 are sequentially arranged. In this embodiment, by providing the gap 49, during the installation process, the upper part of the plug pin 200 installed in the first through hole 41 can be forced through the gap 49 to drive the upper part of the plug pin 200 to bend outward. For example, the plug pin 200 in the first through hole 41 extends roughly in the up-down direction, and the plug pin 200 above the first through hole 41 is bent outward relative to the plug pin 200 in the first through hole 41 after the force is applied outward.

[0038] It should be noted that the condition that the highest end of the pin 200 is higher than the highest end of the blocking portion 50 in the axial direction parallel to the first winding portion 10 can be satisfied alone, or the condition that the blocking portion 50 and the first through hole 41 are spaced apart and distributed to form a gap 49 in the axial direction from the mounting portion 40 to the first winding portion 10 can be satisfied alone. The above conditions can also be satisfied at the same time. The specific settings can be made according to product design requirements, and the bending methods are diverse.

[0039] In some specific embodiments of the present invention, the outer surface of the mounting portion 40 includes a first surface 42, a second surface 43 and a third surface 44, the first surface 42 and the third surface 44 are spaced apart and distributed in a direction parallel to the axis of the first winding portion 10 and connected by the second surface 43, one end of the first through hole 41 is connected to the first surface 42, and the other end of the first through hole 41 is connected to the third surface 44, such as Figure 5 As shown, an open groove 48 is provided on the outer side of the mounting portion 40 and is separated from the first through hole 41. The open groove 48 connects the first surface 42, the second surface 43 and the third surface 44 respectively. The open groove 48 is used to pass the winding wire. The angle between the third surface 44 and the second surface 43 is an obtuse angle.

[0040] That is, the outer surface of the mounting portion 40 mainly includes a first surface 42, a second surface 43 and a third surface 44, and the first surface 42 and the third surface 44 are spaced apart, for example, spaced apart in a direction parallel to the axis of the first winding portion 10 and connected through the second surface 43, that is, the first surface 42 and the third surface 44 are connected in an indirect connection, and the second surface 43 is respectively connected to the first surface 42 and the third surface 44. Moreover, a part of the first through hole 41 is provided on the first surface 42, and another part is provided on the third surface 44, that is, one end of the first through hole 41 is connected to the first surface 42, and the other end of the first through hole 41 is connected to the third surface 44.

[0041] In addition, an opening groove 48 is provided on the outer side of the mounting portion 40 and is spaced apart from the first through hole 41. A portion of the opening groove 48 is provided on the first surface 42, another portion is provided on the second surface 43, and another portion is provided on the third surface 44. That is, the opening groove 48 is connected to the first surface 42, the second surface 43, and the third surface 44, respectively. In this embodiment, the winding wire on the first winding portion 10 can be connected to a portion of the pin 200 extending out of the first through hole 41 after passing through the opening groove 48. For example, the upper portion of the pin 200 extends out of the upper end of the first through hole 41 and is connected to the winding wire. In this embodiment, by providing the opening groove 48, the position of the winding wire can be limited, the winding wire can be prevented from interfering with other structures, and the efficiency and safety of the winding wire can be improved.

[0042] In addition, the angle between the third surface 44 and the second surface 43 is an obtuse angle. For example, the second surface 43 extends approximately in the vertical direction. The third surface 44 is located below the first surface 42 and the angle between the third surface 44 and the second surface 43 is an obtuse angle. The third surface 44 is inclined relative to the second surface 43, which can buffer the bending degree of the winding wire connected between the mounting portion 40 and the first winding portion 10, thereby preventing the winding wire from being cut by the outer surface of the mounting portion 40.

[0043] According to one embodiment of the present invention, the outer surface of the mounting portion 40 further includes a fourth surface 47 which is parallel to the first surface 42 . The third surface 44 is connected to the first flange portion 20 via the fourth surface 47 . A portion of the opening groove 48 is disposed on the fourth surface 47 .

[0044] That is, in this embodiment, the outer surface of the mounting portion 40 mainly includes the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47, the fourth surface 47 is connected to the third surface 44 and the first flange portion 20 respectively, and the third surface 44 is indirectly connected to the first flange portion 20. The first part of the opening groove 48 is provided on the first surface 42, the second part is provided on the second surface 43, the third part is provided on the third surface 44, and the fourth part is provided on the fourth surface 47, that is, the opening groove 48 is connected to the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47 at the same time.

[0045] In this embodiment, by using the fourth surface 47, the area of ​​the region where the third surface 44 is processed on the mounting portion 40 can be reduced, which facilitates processing. In addition, by connecting the opening groove 48 to the fourth surface 47, it is not only convenient to process the opening groove 48 on the outer surface of the mounting portion 40, but also it can be avoided that the wall edge of the opening groove 48 rubs against the winding wire due to the opening groove 48 being too short.

[0046] In some specific embodiments of the present invention, in a direction parallel to the axis of the first winding portion 10, the width dimension of the end of the opening groove 48 away from the second flange portion 30 is smaller than the width dimension of the end close to the second flange portion 30. For example, the axis direction of the first winding portion 10 is the up-down direction, the second flange portion 30 is located below the first flange portion 20, and the width dimension of the upper end of the opening groove 48 is smaller than the width dimension of the lower end of the opening groove 48. The upper section of the opening groove 48 can be a straight groove section extending in the up-down direction, and the lower section of the opening groove 48 can be a trumpet-shaped groove section extending in the up-down direction that is narrow at the top and wide at the bottom. In this embodiment, by limiting the shape of the opening groove 48, the protection effect on the winding wire can be improved, and the winding wire in the first winding portion 10 and the opening groove 48 can be prevented from being disconnected due to the friction of the edge of the opening groove 48.

[0047] According to one embodiment of the present invention, the first cover plate 60 includes: a first connector 65, a second connector 66 and a third connector 67, the second connector 66 is disposed on the first connector 65 and cooperates with the first connector 65 to form a first avoidance space 68 to avoid the mounting portion 40, the second connector 66 is provided with a second through hole 61, and the third connector 67 has a plurality of first grooves 63, and the first grooves 63 are used to limit the lead wire 400. For example, the extension direction of the first groove 63 is parallel to the axial direction of the first winding portion 10.

[0048] That is to say, the first cover plate 60 of the embodiment of the present invention is mainly composed of a first connector 65, a second connector 66 and a third connector 67. The second connector 66 is connected to the first connector 65, and the second connector 66 and the first connector 65 cooperate to form a first avoidance space 68, through which the mounting portion 40 can be avoided, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoidance space 68. That is, in the inner and outer directions, at least a part of the second connector 66 and the first connector 65 are staggered to form a space for the pin 200 to extend outward. Inward here refers to the axial direction of the first winding portion 10, and outward here refers to the side where the second cover plate 70 is located.

[0049] The second connector 66 is provided with a second through hole 61, and one end of the pin 200 passes through the second through hole 61 and is connected to the lead 400. The third connector 67 is provided with a plurality of first grooves 63, for example, each first groove 63 extends in a direction parallel to the axis of the first winding portion 10. At least a portion of the lead 400 can be installed in the first groove 63, so that the lead 400 can be limited.

[0050] In some specific embodiments of the present invention, in a direction perpendicular to the axis of the first winding portion 10, the two sides of the second connector 66 and the third connector 67 are respectively snap-fitted with the second cover plate 70. For example, the left side of the second connector 66 is snap-fitted with the left side of the second cover plate 70, and the right side of the second connector 66 is also snap-fitted with the right side of the second cover plate 70. Similarly, the left side of the third connector 67 is snap-fitted with the left side of the second cover plate 70, and the right side of the third connector 67 is also snap-fitted with the right side of the second cover plate 70, so that snap-fitting at four positions can be achieved. Optionally, the snap-fitting structures on both sides of the second connector 66 correspond, and the snap-fitting structures on both sides of the third connector 67 are symmetrical, and the four snap-fitting positions form a rectangle, which can improve the stability of the combination, expand the range of the combination area, and adopt a symmetrical design to facilitate processing and manufacturing.

[0051] It is understandable that, by adopting the second connector 66, the second connector 66 can not only avoid the plug pin 200 in the inner and outer directions and provide space for the extension of the plug pin 200, but also provide a connection position and a connection structure for the convenient connection between the first cover plate 60 and the second cover plate 70. Similarly, the third connector 67 not only plays a role in limiting the lead 400, but also plays a role in providing a connection position and a connection structure for the convenient connection between the first cover plate 60 and the second cover plate 70.

[0052] In this embodiment, by limiting the direction perpendicular to the axis of the first winding part 10, the two sides of the second connector 66 and the third connector 67 are respectively snap-fitted with the second cover plate 70 to improve the firmness of the combination. During assembly, by limiting the shape of the snap-fit ​​structure, the second cover plate 70 can be covered on the outer side of the first cover plate 60 along the axis parallel to the first winding part 10, and the second cover plate 70 can also be separated from the first cover plate 60 along the axis parallel to the first winding part 10, which is convenient for use and operation. In addition, by adopting the snap-fit ​​method, installation and disassembly are convenient. By snap-fitting the two sides separately, it is also beneficial to improve the overall stability.

[0053] According to an embodiment of the present invention, the inner wall surface of the second cover plate 70 disposed opposite to the first cover plate 60 is provided with: a plurality of second clamping portions 72 and a plurality of crimping protrusions 74 .

[0054] Specifically, a second groove 73 is formed between two adjacent second clamping portions 72, or a second groove 73 is formed between the second clamping portion 72 and the edge of the second cover plate 70. The second groove 73 is used to install the connection part between the pin 200 and the lead 400, and the crimping protrusion 74 is used to abut the lead 400 after the second cover plate 70 is installed to the first cover plate 60.

[0055] That is, the second cover plate 70 is arranged on the outside of at least a part of the first cover plate 60, and the second clamping part 72 and the crimping protrusion 74 are arranged on the inner side of the second cover plate 70. There are multiple second clamping parts 72, and a second groove 73 is formed between two adjacent second clamping parts 72. Alternatively, a second groove 73 is formed between the second clamping part 72 and the edge of the second cover plate 70, for example, multiple second clamping parts 72 are spaced apart and distributed in the left and right directions, and there is a second groove 73 between the leftmost second clamping part 72 and the left edge of the second cover plate 70, and there is a second groove 73 between the rearmost second clamping part 72 and the right edge of the second cover plate 70. In this embodiment, by providing the second groove 73, the connection part between the pin 200 and the lead 400 can be installed to the second groove 73, so that the connection part can be limited. In addition, after the second cover plate 70 is installed to the first cover plate 60, the crimping protrusion 74 can abut against the lead 400 to limit the lead 400. By installing the second cover plate 70 onto the first cover plate 60 , a force may be applied to the lead wire 400 , so that at least a portion of the lead wire 400 is sandwiched between the crimping protrusion 74 and the first cover plate 60 .

[0056] In some specific embodiments of the present invention, the mounting portion 40 has a length direction, a thickness direction and a height direction. The length direction is perpendicular to the axial direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axial direction of the first winding portion 10. There are multiple first through holes 41, and the multiple first through holes 41 are spaced apart and distributed along the length direction.

[0057] That is, the long side of the mounting portion 40 extends along its length direction, the thick side extends along its thickness direction, and the high side extends along its height direction. The length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10. For example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

[0058] In addition, when there are multiple first through holes 41, the multiple first through holes 41 can be spaced apart and distributed along the length direction, for example, spaced apart and distributed along the left-right direction, so as to facilitate the installation of multiple pins 200 at the same time and to facilitate the simultaneous bending and other operations on multiple pins 200. Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by spaced apart and distributed along the length direction, it is helpful to control the orderly arrangement of multiple pins 200 on the mounting portion 40, which is beneficial to the subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when there are multiple pins 200, the mounting portion 40 can adopt a plastic structure, or the inner wall of the first through hole 41 can be coated with insulating material to achieve insulation between two adjacent pins 200 to prevent short circuit.

[0059] According to an embodiment of the present invention, the blocking portion 50 is a solid piece and is in the shape of a flat plate. The long side of the blocking portion 50 extends in the length direction, and the high side of the blocking portion 50 extends in the height direction. In other words, the blocking portion 50 is a solid flat plate structure, and the plurality of first through holes 41 are spaced apart and distributed along the length direction. By using the blocking portion 50, not only can the range of blocking metal beads be expanded, but also the metal beads generated during the metal processing of the plurality of pins 200 can be blocked at the same time. At the same time, the solid flat plate structure is convenient for processing and production.

[0060] Optionally, the motor further includes a shell, in which a coil skeleton 100 and the like are arranged.

[0061] The coil skeleton 100 of the present application is described in detail below in conjunction with specific embodiments.

[0062] The coil bobbin 100 according to the embodiment of the present invention includes: a first winding portion 10 , a first collar portion 20 , a second collar portion 30 , a mounting portion 40 and a blocking portion 50 .

[0063] Specifically, the first winding portion 10 is cylindrical in shape and is used to wind the winding wire. The first collar 20 is provided at one axial end of the first winding portion 10, and the second collar 30 is provided at the other axial end of the first winding portion 10. The mounting portion 40 is provided on the outer periphery of the first collar 20. The mounting portion 40 is provided with a first through hole 41, and the first through hole 41 is used to mount the plug pin 200. The blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second collar 30 and is located on the side of the first through hole 41 close to the axis of the first winding portion 10. The blocking portion 50 can prevent the metal beads generated during the metal treatment of the plug pin 200 from rolling toward the axis of the first winding portion 10.

[0064] In other words, the coil bobbin 100 according to the embodiment of the present invention mainly includes a first winding portion 10 , a first collar portion 20 , a second collar portion 30 , a mounting portion 40 and a blocking portion 50 .

[0065] The first winding part 10 is in a columnar shape, for example, the first winding part 10 is a cylindrical member extending in the up-down direction. The first winding part 10 is used to wind the winding wire, that is, the winding wire can be wound on the first winding part 10 .

[0066] The first flange 20 is provided at one axial end of the first winding part 10, and the second flange 30 is provided at the other axial end of the first winding part 10, for example, the first flange 20 is provided at the upper end of the first winding part 10, and the second flange 30 is provided at the lower end of the first winding part 10. The mounting portion 40 is provided at the outer periphery of the first flange 20, for example, the mounting portion 40 is provided at a position of approximately one-fourth of the outer periphery of the first flange 20. At least one first through hole 41 is provided on the mounting portion 40, that is, a through first through hole 41 is provided, and the first through hole 41 can be used to install the plug pin 200, that is, the plug pin 200 can be installed in the first through hole 41, and the winding wire can be connected to the plug pin 200 during installation. In this embodiment, the shape of the cross section of the plug pin 200 is not limited, for example, the cross section of the plug pin 200 is square, which can prevent the winding wire from sliding.

[0067] Moreover, the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second flange 30, and the blocking portion 50 is located on the side of the first through hole 41 close to the axis of the first winding portion 10. For example, the first flange 20 is located above the second flange 30, and the blocking portion 50 is located on the upper surface of the mounting portion 40. When the coil skeleton 100 of the present invention is applied to a motor, the motor includes a gear assembly 500, and at least a part of the gear assembly 500 is located on one side of the blocking portion 50. For example, the gear assembly 500 includes a plurality of gears meshing with each other, and at least a part of the gears is located on one side of the blocking portion 50. The plug pin 200 is located on the other side of the blocking portion 50, and the blocking portion 50 can prevent the metal beads generated when the plug pin 200 is metal-treated from rolling to the gear assembly 500. For example, when the plug pin 200 is tinned, the solder beads after soldering can be prevented from entering the gear assembly 500, causing the gear assembly 500 to get stuck or even stuck, thereby avoiding abnormal noise.

[0068] Therefore, according to the coil skeleton 100 of the embodiment of the present application, the blocking part 50 can prevent the metal beads generated during the metal treatment of the pin 200 from rolling to the gear assembly 500, which can effectively prevent the gear assembly 500 from being affected by the metal beads, such as causing the motor to get stuck, jammed, or make abnormal noises due to tinning.

[0069] According to one embodiment of the present invention, the mounting portion 40 has a length direction, a thickness direction and a height direction, the length direction is perpendicular to the axial direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axial direction of the first winding portion 10. That is to say, the long side of the mounting portion 40 extends along its own length direction, the thick side extends along its own thickness direction, and the high side extends along its own height direction. The length direction is perpendicular to the axial direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axial direction of the first winding portion 10. For example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

[0070] In this embodiment, by limiting the mounting portion 40 to have a length direction, a thickness direction and a height direction, it is convenient to process and manufacture the mounting portion 40 and to arrange the first through hole 41. For example, a plurality of first through holes 41 are spaced apart and distributed along the length direction, and a pin 200 is installed in each first through hole 41. This is also conducive to arranging the pins 200 in rows.

[0071] In some specific embodiments of the present invention, the blocking portion 50 is a solid structural member, which can expand the range of blocking the metal beads and facilitate processing and production.

[0072] According to an embodiment of the present invention, the blocking portion 50 is in the shape of a flat plate, which is not only convenient for processing and production, but also helps to improve the appearance and can also expand the range of blocking metal beads.

[0073] It should be noted that the blocking portion 50 may be a solid structural member, or may be in the shape of a flat plate, or may satisfy the above conditions at the same time, and the specific configuration may be based on product design requirements.

[0074] According to one embodiment of the present invention, there are multiple first through holes 41, and each first through hole 41 can correspond to one plug pin 200, so that the total number of plug pins 200 can be increased. In the length direction of the mounting portion 40, multiple first through holes 41 are spaced apart and distributed. For example, the length direction of the mounting portion 40 is the left-right direction, and multiple first through holes 41 are spaced apart and distributed along the left-right direction. The edge of the blocking portion 50 exceeds the position of the outermost first through hole 41. For example, in the left-right direction, the left edge of the blocking portion 50 exceeds the leftmost first through hole 41, and the right edge of the blocking portion 50 exceeds the rightmost first through hole 41. This can expand the shielding range, and a blocking portion 50 can be used to protect multiple plug pins 200 during metallization processing.

[0075] In some specific embodiments of the present invention, in the length direction of the mounting portion 40, the length of the blocking portion 50 is not less than the length of the mounting portion 40, that is, the length of the blocking portion 50 is greater than or equal to the length of the mounting portion 40, which can further enhance the protective effect. For example, in the left-right direction, the length of the blocking portion 50 is equal to the length of the mounting portion 40; for another example, in the left-right direction, the length of the blocking portion 50 is greater than the length of the mounting portion 40.

[0076] According to an embodiment of the present invention, the blocking portion 50 and the mounting portion 40 are an integrally formed part, and can be prepared and produced by, for example, integral injection molding.

[0077] In some specific embodiments of the present invention, the first flange portion 20, the blocking portion 50 and the mounting portion 40 are an integrally formed part, and can be prepared and produced by, for example, integral injection molding to facilitate processing.

[0078] According to an embodiment of the present invention, the first flange portion 20, the first winding portion 10, the blocking portion 50 and the mounting portion 40 are an integrally formed part, and can be prepared and produced by, for example, integral injection molding, which is easy to process.

[0079] The present invention further provides a coil assembly, comprising: a pin 200 and a motor frame, the motor frame comprising the coil frame 100 of any of the above embodiments, and the pin 200 is installed in the first through hole 41 of the coil frame 100. Since the coil assembly of the embodiment of the present application comprises the coil frame 100 of any of the above embodiments, and the coil frame 100 has a protective effect, the coil assembly of the embodiment of the present application has the same effect, which will not be described in detail here.

[0080] According to one embodiment of the present invention, the motor skeleton includes: a first skeleton and a second skeleton 300, the first skeleton is a coil skeleton 100, and the second skeleton 300 is connected to the first skeleton. For example, the first skeleton is located above the second skeleton 300, the first skeleton can be defined as an upper skeleton, and the second skeleton 300 is defined as a lower skeleton. The first skeleton is the coil skeleton 100 of any of the above embodiments. Optionally, the first skeleton and the second skeleton 300 can be coaxially arranged.

[0081] The bending process of the pin 200 of the embodiment of the present application is described in detail below in conjunction with specific embodiments.

[0082] A method for assembling a coil assembly according to an embodiment of the present invention comprises the following steps: Install the pin 200 in the first through hole 41, as shown in FIG. Figure 7 As shown, the pin 200 includes a first segment 201, a second segment 202 and a third segment 203. The first segment 201 extends out of the first through hole 41 and is located on the same side of the mounting portion 40 as the blocking portion 50. The second segment 202 is located in the first through hole 41. The third segment 203 extends out of the first through hole 41 and extends toward a side close to the second flange portion 30. In a direction parallel to the axis of the first winding portion 10, the highest end of the first segment 201 is higher than the highest end of the blocking portion 50. A force is applied to the first segment 201 along a direction from the blocking portion 50 toward the axis away from the first winding portion 10 , so as to drive the first segment 201 to bend.

[0083] That is, in the direction parallel to the axis of the first winding portion 10, the highest end of the pin 200 is higher than the highest end of the blocking portion 50. For example, in the up-down direction, the highest end of the pin 200 installed in the first through hole 41 is higher than the highest end of the blocking portion 50. During the installation process, a force can be applied from the inner side of the installation portion 40 through the blocking portion 50 to the upper end of the pin 200, driving the upper end of the pin 200 to bend outward. In this embodiment, by limiting the position of the highest end of the pin 200, during the installation process, a force can be applied to the upper part of the pin 200 installed in the first through hole 41 through the blocking portion 50 in the direction from the inside to the outside, driving the upper part of the pin 200 to bend outward.

[0084] According to one embodiment of the present invention, the number of first through holes 41 and the number of plug pins 200 are respectively multiple and one-to-one corresponding, and a force is simultaneously applied to the multiple first segments 201 along the direction from the blocking portion 50 to the axis away from the first winding portion 10. By providing multiple first through holes 41, it is convenient to install multiple plug pins 200 at the same time, and it is convenient to perform operations such as bending multiple plug pins 200 at the same time. Each first through hole 41 can correspond to one plug pin 200, which can increase the total number of plug pins 200. In addition, by distributing the multiple first through holes 41 at intervals along the extension direction of the mounting portion 40, it is helpful to control the orderly arrangement of the multiple plug pins 200 on the mounting portion 40, which is beneficial to the subsequent installation of the first cover plate 60 and the second cover plate 70.

[0085] The present invention also provides an assembly method of a coil assembly, in which the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49 in the axial direction from the mounting portion 40 to the first winding portion 10, and the blocking portion 50 can prevent the metal beads generated during the metal treatment of the pin 200 from rolling toward the axial direction of the first winding portion 10; The assembly method comprises the following steps: The plug pin 200 is installed in the first through hole 41. The plug pin 200 includes a first segment 201, a second segment 202 and a third segment 203. The first segment 201 extends out of the first through hole 41 and is located on the same side of the mounting portion 40 as the blocking portion 50. The second segment 202 is located in the first through hole 41. The third segment 203 extends out of the first through hole 41 and extends toward one side of the second collar-shaped portion 30. A force is applied from the gap 49 to the first segment 201 away from the blocking portion 50 , driving the first segment 201 to bend.

[0086] That is, in the axial direction from the mounting portion 40 to the first winding portion 10, the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49. That is, along a direction from the outside to the inside, the first through hole 41, the gap 49 and the blocking portion 50 are sequentially arranged. In this embodiment, by providing the gap 49, during the installation process, the upper part of the plug pin 200 installed in the first through hole 41 can be forced through the gap 49 to drive the upper part of the plug pin 200 to bend outward. For example, the plug pin 200 in the first through hole 41 extends roughly in the up-down direction, and the plug pin 200 above the first through hole 41 is bent outward relative to the plug pin 200 in the first through hole 41 after the force is applied outward.

[0087] It should be noted that the condition that the highest end of the pin 200 is higher than the highest end of the blocking portion 50 in the axial direction parallel to the first winding portion 10 can be satisfied alone, or the condition that the blocking portion 50 and the first through hole 41 are spaced apart and distributed to form a gap 49 in the axial direction from the mounting portion 40 to the first winding portion 10 can be satisfied alone. The above conditions can also be satisfied at the same time. The specific settings can be made according to product design requirements, and the bending methods are diverse.

[0088] According to one embodiment of the present invention, the number of first through holes 41 and the number of plug pins 200 are respectively multiple and one-to-one corresponding, and a force is applied from the gap 49 to the multiple first segments 201 away from the blocking portion 50, driving the multiple first segments 201 to bend simultaneously. By providing multiple first through holes 41, it is convenient to install multiple plug pins 200 at the same time, and it is convenient to perform operations such as bending multiple plug pins 200 at the same time. Each first through hole 41 can correspond to one plug pin 200, which can increase the total number of plug pins 200. In addition, by distributing the multiple first through holes 41 at intervals along the extension direction of the mounting portion 40, it is convenient to control the orderly arrangement of the multiple plug pins 200 on the mounting portion 40, which is convenient for the subsequent installation of the first cover plate 60 and the second cover plate 70.

[0089] In addition, when there are multiple pins 200, the mounting portion 40 may be made of a plastic structure, or the inner wall of the first through hole 41 may be coated with insulating material to achieve insulation between two adjacent pins 200 to prevent short circuits.

[0090] In some specific embodiments of the present invention, the gap 49 is open on the side away from the mounting portion 40 in a direction parallel to the axis of the first winding portion 10. For example, the height direction of the gap 49 is in the up and down direction, and the top of the gap 49 is open, so that a force-applying tool can be inserted from above. According to one embodiment of the present application, the blocking portion 50 extends in a direction perpendicular to the axis of the first winding portion 10, and at least one side of the gap 49 is open in the extending direction of the blocking portion 50. For example, the length direction of the gap 49 is the left-right direction, and the left and right sides of the gap 49 are open, and a force-applying tool can be inserted through the open position.

[0091] It should be noted that the condition that the gap 49 is open on one side away from the mounting portion 40 in a direction parallel to the axis of the first winding portion 10 can be satisfied alone, or the condition that at least one side of the gap 49 is open in the extension direction of the blocking portion 50 can be satisfied alone, or both conditions can be satisfied at the same time, so that the bending method of the pin 200 is diverse and flexible.

[0092] In some specific embodiments of the present invention, the blocking portion 50 is a solid structural member, which can expand the range of blocking the metal beads and facilitate processing and production.

[0093] In some specific embodiments of the present invention, the motor skeleton further includes a second skeleton 300, the second skeleton 300 includes: a second winding portion 301, a third flange portion 302 and a fourth flange portion 303, the second winding portion 301 is columnar and is used to wind the winding wire, the third flange portion 302 is arranged at one axial end of the second winding portion 301, the fourth flange portion 303 is arranged at the other axial end of the second winding portion 301, the third flange portion 302 is connected to the second flange portion 30, and as shown Figure 6 As shown, a avoiding groove 304 is provided at the connection position of the two to avoid the third section 203, so as to avoid affecting the bending of the pin 200 and the lead 400. In addition, the inner wall of the first cover plate 60 can be avoided to facilitate the installation of the first cover plate 60.

[0094] The mounting portion 40 according to the embodiment of the present application is described in detail below.

[0095] The mounting portion 40 is arranged on the outer periphery of the first collar-shaped portion 20. The mounting portion 40 is provided with a first through hole 41. The first through hole 41 is used to install the pin 200. The outer surface of the mounting portion 40 includes a first surface 42, a second surface 43 and a third surface 44. The first surface 42 and the third surface 44 are spaced apart and connected by the second surface 43. One end of the first through hole 41 is connected to the first surface 42, and the other end of the first through hole 41 is connected to the third surface 44. The outer side of the mounting portion 40 is provided with an open groove 48 spaced apart from the first through hole 41. The open groove 48 is respectively connected to the first surface 42, the second surface 43 and the third surface 44. The open groove 48 is used to pass the winding wire. The angle between the third surface 44 and the second surface 43 is an obtuse angle.

[0096] In other words, the mounting portion 40 is provided on the outer periphery of the first flange 20. For example, the mounting portion 40 is provided at approximately one-fourth of the outer periphery of the first flange 20. The mounting portion 40 is provided with at least one first through hole 41, that is, a through first through hole 41 is provided. The first through hole 41 can be used to install the plug pin 200. That is, the plug pin 200 can be installed in the first through hole 41, and the winding wire can be connected to the plug pin 200 during installation. In this embodiment, the shape of the cross section of the plug pin 200 is not limited. For example, the cross section of the plug pin 200 is square, which can prevent the winding wire from sliding.

[0097] The outer surface of the mounting portion 40 mainly includes a first surface 42, a second surface 43 and a third surface 44. The first surface 42 and the third surface 44 are spaced apart, for example, spaced apart in a direction parallel to the axis of the first winding portion 10 and connected through the second surface 43. That is, the first surface 42 and the third surface 44 are connected in an indirect connection, and the second surface 43 is respectively connected to the first surface 42 and the third surface 44. Moreover, a part of the first through hole 41 is provided on the first surface 42, and another part is provided on the third surface 44, that is, one end of the first through hole 41 is connected to the first surface 42, and the other end of the first through hole 41 is connected to the third surface 44.

[0098] An open groove 48 is provided on the outer side of the mounting portion 40 and is spaced apart from the first through hole 41. A portion of the open groove 48 is provided on the first surface 42, another portion is provided on the second surface 43, and another portion is provided on the third surface 44. That is, the open groove 48 is connected to the first surface 42, the second surface 43, and the third surface 44, respectively. In this embodiment, the winding wire on the first winding portion 10 can be connected to a portion of the pin 200 extending out of the first through hole 41 after passing through the open groove 48. For example, the upper portion of the pin 200 extends out of the upper end of the first through hole 41 and is connected to the winding wire. In this embodiment, by providing the open groove 48, the position of the winding wire can be limited, the winding wire can be prevented from interfering with other structures, and the efficiency and safety of the winding wire can be improved.

[0099] The angle between the third surface 44 and the second surface 43 is an obtuse angle. For example, the second surface 43 extends approximately in the vertical direction. The third surface 44 is located below the first surface 42 and the angle between the third surface 44 and the second surface 43 is an obtuse angle. The third surface 44 is inclined relative to the second surface 43, which can buffer the bending degree of the winding wire connected between the mounting portion 40 and the first winding portion 10, thereby preventing the winding wire from being cut by the outer surface of the mounting portion 40.

[0100] According to an embodiment of the present invention, the first surface 42 and the second surface 43 are transitionally connected by a first arc surface 45; and / or, the second surface 43 and the third surface 44 are transitionally connected by a second arc surface 46. By adopting the transition connection, the winding wire can be further protected, the winding wire can be smoothly routed, and it is convenient for the winding wire to enter and lock in the opening groove 48. In addition, when the first surface 42 and the second surface 43 are transitionally connected by the first arc surface 45, it is convenient to apply a force to the plug pin 200 from the gap between the blocking portion 50 and the plug pin 200, or through the blocking portion 50 from the inside to the outside, so as to drive the plug pin 200 to bend; and it is convenient to wind the plug pin 200 and reduce winding obstacles.

[0101] In some specific embodiments of the present invention, the second surface 43 is closer to the second flange 30 relative to the first surface 42. For example, the first flange 20 is located above the second flange 30, and the first surface 42 is located above the second surface 43. In the up-down direction, the second surface 43 is closer to the second flange 30 relative to the first surface 42. In this embodiment, by using the second surface 43 to be closer to the second flange 30 relative to the first surface 42, it is convenient for the winding wire to enter the opening groove 48 at a shorter distance after being wound by the first winding part 10.

[0102] According to an embodiment of the present invention, the first through hole 41 includes a first hole section 411 and a second hole section 412 .

[0103] Specifically, one end of the first hole segment 411 is connected to the first surface 42, the first end of the second hole segment 412 is connected to the other end of the first hole segment 411, the second end of the second hole segment 412 is connected to the second surface 43, and the third end of the second hole segment 412 is connected to the third surface 44. For example, the first through hole 41 includes the first hole segment 411 and the second hole segment 412 distributed up and down, the upper end of the first hole segment 411 is connected to the first surface 42, the upper end of the second hole segment 412 is connected to the lower end of the first hole segment 411, and the lower end of the second hole segment 412 is connected to both the second surface 43 and the third surface 44. In this embodiment, since the second hole segment 412 is connected to both the second surface 43 and the third surface 44, one end of the pin 200 can extend through the first hole segment 411, and the other end of the pin 200 can be bent outward toward the side where the second surface 43 is located, and can also have a certain distance from the third surface 44 to avoid contact with the winding wire passing through the third surface 44.

[0104] In some specific embodiments of the present invention, the coil skeleton 100 further includes: a blocking portion 50, the blocking portion 50 protrudes from the first surface 42 and is located on the side of the first through hole 41 close to the axis of the first winding portion 10, and the blocking portion 50 can prevent the metal beads generated during the metal treatment of the pin 200 from rolling toward the axis of the first winding portion 10. In other words, the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second flange portion 30 and is located on the side of the first through hole 41 close to the axis of the first winding portion 10.

[0105] The blocking portion 50 protrudes from the surface of the mounting portion 40 on the side away from the second collar portion 30, and the blocking portion 50 is located on the side of the first through hole 41 close to the axis of the first winding portion 10. For example, the first collar portion 20 is located above the second collar portion 30, and the blocking portion 50 is located on the upper surface of the mounting portion 40.

[0106] Furthermore, at least a portion of the gear assembly 500 is located on one side of the blocking portion 50. For example, the gear assembly 500 includes a plurality of gears meshing with each other, and at least a portion of the gears are located on one side of the blocking portion 50. The plug pin 200 is located on the other side of the blocking portion 50. The blocking portion 50 can prevent metal beads generated during metal treatment of the plug pin 200 from rolling onto the gear assembly 500. For example, when tinning the plug pin 200, solder beads can be prevented from entering the gear assembly 500 to cause jamming or even jamming.

[0107] According to one embodiment of the present invention, the mounting portion 40 has a length direction, a thickness direction and a height direction, the length direction is perpendicular to the axial direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, the height direction is parallel to the axial direction of the first winding portion 10, the first surface 42 and the third surface 44 are spaced apart and distributed in the height direction, and the second surface 43 is located on one side of the mounting portion 40 in the thickness direction.

[0108] That is, the long side of the mounting portion 40 extends along its length direction, the thick side extends along its thickness direction, and the high side extends along its height direction. The length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10. For example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

[0109] Optionally, there are multiple first through holes 41, and the multiple first through holes 41 are spaced apart along the length direction, for example, spaced apart along the left-right direction, so as to facilitate the installation of multiple pins 200 at the same time, and facilitate operations such as bending multiple pins 200 at the same time. Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by distributing the multiple first through holes 41 at intervals along the length direction, it is helpful to control the orderly arrangement of the multiple pins 200 on the mounting portion 40, which is beneficial to the subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when there are multiple pins 200, the mounting portion 40 can adopt a plastic structure, or the inner wall of the first through hole 41 can be coated with insulating material to achieve insulation between two adjacent pins 200 to prevent short circuits.

[0110] In some specific embodiments of the present invention, the outer surface of the mounting portion 40 also includes a fourth surface 47 , which is parallel to the first surface 42 , the third surface 44 is connected to the first flange portion 20 via the fourth surface 47 , and a portion of the opening groove 48 is connected to the fourth surface 47 .

[0111] That is, in this embodiment, the outer surface of the mounting portion 40 mainly includes the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47, the fourth surface 47 is connected to the third surface 44 and the first flange 20 respectively, and the third surface 44 is indirectly connected to the first flange 20. The first part of the opening groove 48 is provided on the first surface 42, the second part is provided on the second surface 43, the third part is provided on the third surface 44, and the fourth part is provided on the fourth surface 47, that is, the opening groove 48 is connected to the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47 at the same time. In addition, the fourth surface 47 is parallel to the first surface 42, which is convenient for processing.

[0112] In this embodiment, by using the fourth surface 47, the area of ​​the region where the third surface 44 is processed on the mounting portion 40 can be reduced, which facilitates processing. In addition, by connecting the opening groove 48 to the fourth surface 47, it is not only convenient to process the opening groove 48 on the outer surface of the mounting portion 40, but also it can be avoided that the wall edge of the opening groove 48 rubs against the winding wire due to the opening groove 48 being too short.

[0113] According to one embodiment of the present invention, in the thickness direction, the end of the opening groove 48 on the third surface 44 is close to the central axis of the first winding portion 10 relative to the first through hole 41 on the third surface 44. For example, the opening groove 48 on the third surface 44 extends inward, and the minimum distance between the inner wall of the opening groove 48 on the third surface 44 and the central axis of the first winding portion 10 is L1, and the minimum distance between the inner wall of the first through hole 41 adjacent to the opening groove 48 and the central axis of the first winding portion 10 is L2, and L1<L2. In this embodiment, in the thickness direction, the end of the opening groove 48 on the third surface 44 is close to the central axis of the first winding portion 10 relative to the first through hole 41 on the third surface 44, which is beneficial to protect the winding wire and prevent the winding wire from contacting the pin 200 passing through the first through hole 41 on the third surface 44.

[0114] In some specific embodiments of the present invention, in the thickness direction, the first through hole 41 on the first surface 42 is close to the central axis of the first winding portion 10 relative to the opening groove 48 on the first surface 42. For example, the opening groove 48 on the first surface 42 extends inward, and the minimum distance between the inner wall of the opening groove 48 on the first surface 42 and the central axis of the first winding portion 10 is L3, and the minimum distance between the inner wall of the first through hole 41 on the first surface 42 adjacent to the opening groove 48 and the central axis of the first winding portion 10 is L4, L4 < L3, so that the pin 200 extending from the first through hole 41 on the first surface 42 is convenient for connection with the winding wire.

[0115] According to one embodiment of the present invention, in the height direction, the width dimension of the end of the opening groove 48 away from the second flange 30 is smaller than the width dimension of the end close to the second flange 30. For example, the axial direction of the first winding part 10 is the up-down direction, the second flange 30 is located below the first flange 20, and the width dimension of the upper end of the opening groove 48 is smaller than the width dimension of the lower end of the opening groove 48. The upper section of the opening groove 48 can be a straight groove section extending in the up-down direction, and the lower section of the opening groove 48 can be a trumpet-shaped groove section extending in the up-down direction, which is narrow at the top and wide at the bottom. In this embodiment, by limiting the shape of the opening groove 48, the protection effect of the winding wire can be improved, and the winding wire in the first winding part 10 and the opening groove 48 can be prevented from being disconnected due to the friction of the edge of the opening groove 48. In addition, it is also beneficial to lock the winding wire in the opening groove 48.

[0119] The outer surface of the mounting portion 40 mainly includes a first surface 42, a second surface 43 and a third surface 44. The first surface 42 and the third surface 44 are spaced apart in the height direction, that is, they are spaced apart in the direction parallel to the axis of the first winding portion 10 and connected through the second surface 43. In other words, the first surface 42 and the third surface 44 are connected in an indirect connection manner, and the second surface 43 is connected to the first surface 42 and the third surface 44 respectively. The second surface 43 is located on one side of the mounting portion 40 in the thickness direction.

Each first through hole 41 can correspond to a plug pin 200, which can increase the total number of plug pins 200. In addition, by distributing the plurality of first through holes 41 spaced apart and distributed along the length direction, it is helpful to control the orderly arrangement of the plurality of plug pins 200 on the mounting portion 40, which is helpful for the subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when the number of the plug pins 200 is plural, the mounting portion 40 can adopt a plastic structure, or the inner wall of the first through hole 41 can be coated with an insulating material to achieve insulation between two adjacent plug pins 200 to prevent short circuit.

[0121] At least a portion of the first cover plate 60 is disposed on a side of the mounting portion 40 away from the axis of the first winding portion 10, that is, the first cover plate 60 can cover the outside of the mounting portion 40, for example, on a projection plane extending in the vertical direction with a height and in the horizontal direction with a width, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It can be understood that, in this embodiment, the side close to the axis direction of the first winding portion 10 is the inner side, and the side away from the axis direction of the first winding portion 10 is the outer side.

In addition, by providing the second through hole 61 on the first cover plate 60, one end of the plug pin 200 passes through the second through hole 61 and is connected to the lead wire 400. For example, one end of the plug pin 200 passes through the second through hole 61 and is welded to the lead wire 400. Under the shielding of the first cover plate 60, the metal material during welding is not easy to splash into the inner side of the gear assembly 500.

[0122] In addition, the first cover plate 60 of the embodiment of the present invention is mainly composed of a first connector 65, a second connector 66 and a third connector 67. The second connector 66 is connected to the first connector 65, and the second connector 66 and the first connector 65 cooperate to form a first avoidance space 68.

[0125] In addition, in the length direction, the two sides of the second connector 66 and the third connector 67 are respectively snap-fitted with the second cover plate 70. For example, the left side of the second connector 66 is snap-fitted with the left side of the second cover plate 70, and the right side of the second connector 66 is also snap-fitted with the right side of the second cover plate 70. Similarly, the left side of the third connector 67 is snap-fitted with the left side of the second cover plate 70, and the right side of the third connector 67 is also snap-fitted with the right side of the second cover plate 70, so that snap-fitting at four positions can be achieved.

The snap-on protrusion 64 and the snap-on groove 71 can be detachably connected to achieve installation and removal between the second cover plate 70 and the first cover plate 60. In this embodiment, by using the snap-on protrusion 64 and the snap-on groove 71 to cooperate, it is easy to operate, and installation and removal are convenient.

[0127] In some specific embodiments of the present invention, in the length direction, the second connector 66 and the third connector 67 are provided with a snap-fit ​​groove 71 on both sides, and the second cover plate 70 is provided with a snap-fit ​​protrusion 64 at a position corresponding to the snap-fit ​​groove 71.

For example, the second connecting body 66 is provided with a clamping groove 71 on both sides, and the third connecting body 67 is provided with a clamping protrusion 64 on both sides; for another example, the second connecting body 66 is provided with a clamping protrusion 64 on both sides, and the third connecting body 67 is provided with a clamping groove 71 on both sides, which is convenient for operation.

[0129] It can be seen from the above-mentioned combining methods that there are various ways of clamping the second cover plate 70 and the first cover plate 60 .

[0130] In some specific embodiments of the present invention, the number of the clamping protrusions 64 and the clamping grooves 71 are multiple and correspond one to one. In the height direction, the multiple clamping protrusions 64 are spaced apart. For example, there are four clamping protrusions 64 in total, two clamping protrusions 64 are close to the top and form a group, and two clamping protrusions 64 are close to the bottom and form a group. In this embodiment, by limiting the multiple clamping protrusions 64 to be spaced apart, it is possible to achieve position limiting at different positions and improve structural stability.

[0131] According to one embodiment of the present invention, Figures 8 to 10 As shown, along the radial direction of the first winding part 10, the cross-section of the clamping protrusion 64 is in the shape of a triangle, and the outer side of the clamping protrusion 64 includes a first side, a second side 641 and a third side 642, the first side is connected to the side of the second connecting body 66 or the third connecting body 67, the second side 641 is spaced apart from the first connecting body 65, the third side 642 is connected to the first side and the second side 641 respectively, and the angle between the third side 642 and the second side 641 is an acute angle. In this embodiment, by limiting the shape of the clamping protrusion 64, the second cover plate 70 can be slidably installed along the axial direction parallel to the first winding part 10. In addition, the clamping protrusion 64 of the above shape can realize the circumferential limitation of the second cover plate 70.

[0132] In some specific embodiments of the present invention, the second connector 66 and the third connector 67 are spaced apart in the height direction, for example, the second connector 66 is located above and spaced apart from the third connector 67. In this embodiment, the space formed by the spacing can avoid the connection part between the lead 400 and the plug pin 200, which facilitates the connection between the lead 400 and the plug pin 200 and the connection operation.

[0133] In the height direction, the plurality of first through holes 41 correspond to the plurality of first grooves 63 one by one. For example, at least a portion of the first through hole 41 is located above a first groove 63. After a pin 200 is inserted into the first through hole 41, the lower end extends out of the first through hole 41. At least a portion of the lead wire 400 can be installed in the first groove 63. One lead wire 400 corresponds to and is connected to one pin 200. In this embodiment, by adopting a one-to-one correspondence between the plurality of first through holes 41 and the plurality of first grooves 63, the structural orderliness can be improved.

[0134] It should be noted that the second connector 66 and the third connector 67 can be distributed apart in the height direction, or the plurality of first through holes 41 and the plurality of first grooves 63 can correspond one to one in the height direction. The above conditions can also be met at the same time. The specific design can be based on product requirements, with strong flexibility.

The blocking portion 50 can prevent metal beads generated during metal processing of the pin 200 from rolling toward the axis of the first winding portion 10, and the blocking portion 50 is detachably connected to the first cover plate 60.

[0136] In some specific embodiments of the present invention, Figure 4 As shown, the blocking portion 50 includes a body 51 , a first extending portion 52 and a second extending portion 53 .

[0137] Specifically, the body 51 is located on the side of the first cover plate 60 close to the axis direction of the first winding part 10, and can prevent the metal beads generated when the metal treatment of the plug pin 200 rolls toward the axis direction of the first winding part 10. For example, the axis of the first winding part 10 is provided on the inner side of the body 51, and the first through hole 41 is provided on the outer side of the body 51. After the plug pin 200 is installed, the body 51 is located between the axis of the first winding part 10 and at least a part of the plug pin 200. When the plug pin 200 is metal treated, such as tinning, the tin beads are blocked by the body 51 and will not roll toward the inside of the gear assembly 500 close to the axis of the first winding part 10.

[0138] In the length direction, one end of the first extension part 52 is connected to the end of the body 51, and the other end of the first extension part 52 is connected to the second extension part 53. For example, the length direction is the left-right direction, the axial direction close to the first winding part 10 is the rear end, and the axial direction away from the first winding part 10 is the front end. The front end of the first extension part 52 is connected to the right end of the body 51, and the rear end of the first extension part 52 is connected to the left end of the second extension part 53. For another example, the front end of the first extension part 52 is connected to the left end of the body 51, and the rear end of the first extension part 52 is connected to the right end of the second extension part 53. In this embodiment, the second extension part 53, the first extension part 52 and the first winding part 10 can cooperate to form a "J"-shaped piece with an opening facing the axial direction of the first winding part 10. The first connecting body 65 has a second avoidance space 62, and the second extension part 53 is located in the second avoidance space 62, which can improve the tightness of the combination, improve the protection effect, and improve the compactness of the structure. The second extension part 53 is detachably connected to the first cover plate 60. The detachable connection methods include but are not limited to snap connection, threaded connection, bolt connection, etc. In this embodiment, by using the second extension portion 53 , the second cover plate 70 can be limited in a direction parallel to the axis of the first winding portion 10 .

[0139] According to one embodiment of the present invention, the first collar 20 overlaps the first connector 65 in a direction parallel to the axis of the first winding portion 10. For example, the axis of the first winding portion 10 is in the up-down direction, and the lower end of the first connector 65 contacts the first collar 20. In this embodiment, not only a sealing effect can be achieved, but also a supporting effect is provided for the first connector 65.

The detachable connection method here includes but is not limited to snap connection, threaded connection, bolt connection, etc.

[0142] The inner wall surface of the second cover plate 70 which is arranged opposite to the first cover plate 60 is provided with: a plurality of second clamping parts 72 and a plurality of crimping protrusions 74, a second groove 73 is formed between two adjacent second clamping parts 72, or a second groove 73 is formed between the second clamping part 72 and the edge of the second cover plate 70, the second groove 73 is used for installing the connection part between the pin 200 and the lead 400, and the crimping protrusion 74 is used for abutting the lead 400 after the second cover plate 70 is installed to the first cover plate 60.

[0143] In other words, the second cover plate 70 is disposed on a side of the first cover plate 60 away from the mounting portion 40, that is, the second cover plate 70 is disposed on the outside of the first cover plate 60. For example, on a projection plane extending in the vertical direction with a height and in the horizontal direction with a width, the orthographic projection of the second cover plate 70 covers the orthographic projection of the first cover plate 60. In this embodiment, the second cover plate 70 can shield the lead wire 400 and the connection portion between the lead wire 400 and the plug pin 200, thereby improving the aesthetics, structural stability and safety, and preventing the connection portion between the lead wire 400 and the plug pin 200 and the lead wire 400 from being affected by the external environment.

[0144] The second cover plate 70 is detachably connected to the first cover plate 60 , and the detachable connection method here includes but is not limited to snap connection, threaded connection, bolt connection, etc.

[0145] In addition, the inner wall surface of the second cover plate 70 which is arranged opposite to the first cover plate 60 is provided with: a plurality of second clamping portions 72 and a plurality of crimping protrusions 74, a second groove 73 is formed between two adjacent second clamping portions 72, or a second groove 73 is formed between the second clamping portion 72 and the edge of the second cover plate 70, the second groove 73 is used for installing the connection part between the pin 200 and the lead 400, and the crimping protrusion 74 is used for abutting the lead after the second cover plate 70 is installed to the first cover plate 60.

[0146] That is, the second cover plate 70 is arranged on the outside of at least a part of the first cover plate 60, and the second clamping part 72 and the crimping protrusion 74 are arranged on the inner side of the second cover plate 70. There are multiple second clamping parts 72, and a second groove 73 is formed between two adjacent second clamping parts 72. Alternatively, a second groove 73 is formed between the second clamping part 72 and the edge of the second cover plate 70, for example, multiple second clamping parts 72 are spaced apart and distributed in the left and right directions, and there is a second groove 73 between the leftmost second clamping part 72 and the left edge of the second cover plate 70, and there is a second groove 73 between the rearmost second clamping part 72 and the right edge of the second cover plate 70. In this embodiment, by providing the second groove 73, the connection part between the pin 200 and the lead 400 can be installed to the second groove 73, so that the connection part can be limited. In addition, after the second cover plate 70 is installed to the first cover plate 60, the crimping protrusion 74 can abut against the lead 400 to limit the lead 400. By installing the second cover plate 70 onto the first cover plate 60 , a force may be applied to the lead wire 400 , so that at least a portion of the lead wire 400 is sandwiched between the crimping protrusion 74 and the first cover plate 60 .

[0147] According to one embodiment of the present invention, the mounting portion 40 has a length direction, a thickness direction and a height direction. The length direction is perpendicular to the axial direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axial direction of the first winding portion 10. A plurality of first through holes 41 are spaced apart and distributed along the length direction.

[0148] That is, the long side of the mounting portion 40 extends along its length direction, the thick side extends along its thickness direction, and the high side extends along its height direction. The length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to a radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10. For example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

[0149] In some specific embodiments of the present invention, Fig.14 As shown, the second cover plate 70 includes: a baffle plate 75 and a connecting plate 76. The baffle plate 75 is located on a side of the first cover plate 60 away from the mounting portion 40. Fig.12 As shown, the inner wall of the baffle 75 is provided with a second clamping portion 72 and a crimping protrusion 74, and the connecting plate 76 is provided on both sides of the baffle 75 in the length direction. The connecting plate 76 cooperates with the baffle 75 to form a "door"-like shape. For example, the baffle 75 extends in the up-down direction, at least a portion of the first cover 60 is located inside the baffle 75, the inner wall of the baffle 75 is provided with a second clamping portion 72 and a crimping protrusion 74, and the left and right sides of the baffle 75 are respectively provided with connecting plates 76.

In addition, the connecting plate 76 is detachably connected to the first cover 60, and the detachable connection method here includes but is not limited to clamping, threaded connection, bolt connection, etc. In this embodiment, by arranging the second clamping portion 72 and the crimping protrusion 74 on the inner wall of the baffle 75, it is not only convenient for processing, but also convenient for realizing the limit of the lead 400 and the like. The connection plate 76 and the baffle plate 75 are limited to form a “door” shape, so that the assembly between the second cover plate 70 and the first cover plate 60 is facilitated.

[0150] According to an embodiment of the present invention, the second cover plate 70 further includes: a plurality of limiting protrusions 77, which are arranged at one end of the baffle plate 75 in a direction parallel to the axis of the first winding portion 10, for example, at the lower end of the baffle plate 75. A limiting groove 78 is formed between two adjacent limiting protrusions 77. In a direction parallel to the axis of the first winding portion 10, the limiting groove 78, the crimping protrusion 74 and the second groove 73 are located in corresponding positions, and the lead wire 400 crimped by the crimping protrusion 74 can pass through the limiting groove 78. In this embodiment, the limiting groove 78 is used to not only facilitate the lead wire 400 to pass through, but also to limit the lead wire 400, and at the same time, the limiting protrusion 77 can protect the inside of the second cover plate 70. In some specific embodiments of the present invention, along the thickness direction of the baffle 75, for example, along the front-to-back direction, the thickness of the limiting protrusion 77 and the thickness of the second clamping portion 72 are both greater than the thickness of the crimping protrusion 74, which can avoid excessive force on the lead 400 during the pressing process of the lead 400, and avoid the thickness of the second cover plate 70 being too high due to the need to accommodate the lead 400.

[0151] According to an embodiment of the present invention, the depth of the limiting groove 78 is less than the depth of the second groove 73 , so that the lead wire 400 can be limited while the lead wire 400 is not easily pulled outward from the second groove 73 .

[0152] In some specific embodiments of the present invention, the first cover plate 60 includes: a first connecting body 65 , a second connecting body 66 and a third connecting body 67 .

For example, the extension direction of the first grooves 63 is parallel to the axial direction of the first winding portion 10.

[0154] The baffle 75 is disposed opposite to the second connector 66 and the third connector 67 in a direction perpendicular to the axis of the first winding portion 10 , and the connecting plate 76 is respectively engaged with the second connector 66 and the third connector 67 .

[0155] That is to say, the first cover plate 60 of the embodiment of the present invention is mainly composed of a first connecting body 65, a second connecting body 66 and a third connecting body 67. The second connecting body 66 is connected to the first connecting body 65, and the second connecting body 66 and the first connecting body 65 cooperate to form a first avoidance space 68. The installation part 40 can be avoided through the first avoidance space 68, that is, after the first cover plate 60 is installed, the installation part 40 can extend into the first avoidance space 68.

[0156] The second connector 66 is provided with a second through hole 61, and one end of the pin 200 passes through the second through hole 61 and is connected to the lead 400. The third connector 67 is provided with a plurality of first grooves 63, for example, each first groove 63 extends in a direction parallel to the axis of the first winding portion 10. At least a portion of the lead 400 can be installed in the first groove 63, so that the lead 400 can be limited.

[0157] In addition, when the axial direction of the first winding portion 10 is the up-down direction, the second connector 66 and the third connector 67 can be spaced apart and distributed along the direction from top to bottom. At the same time, a baffle 75 can be arranged opposite to the second connector 66 and the third connector 67 in the direction from inside to outside, so as to protect the second connector 66 and the third connector 67 and the lead 400.

[0158] In addition, the connecting plate 76 is respectively engaged with the second connecting body 66 and the third connecting body 67 to facilitate installation and disassembly.

[0159] According to an embodiment of the present invention, the first connecting body 65 includes a first connecting portion 651 and a second connecting portion 652 .

[0160] Specifically, the first connection portion 651 is installed on a side of the mounting portion 40 away from the first winding portion 10, and the first connection portion 651 extends in a direction parallel to the axis of the first winding portion 10, for example, the first connection portion 651 extends in the up-down direction and is located outside the mounting portion 40. The second connection body 66 and the third connection body 67 are installed on the first connection portion 651, and the second connection portion 652 is installed at one end of the first connection portion 651 in a direction parallel to the axis of the first winding portion 10, for example, the second connection portion 652 is located at the upper end of the first connection portion 651. The second connection portion 652 and the first connection portion 651 can cooperate to form a first avoidance space 68, and the mounting portion 40 and at least a portion of the pin 200 can be installed in the first avoidance space 68. A portion of the second connection portion 652 extends out of the outer surface of the first connection portion 651, for example, the outer side of the second connection portion 652 protrudes from the outer surface of the first connection portion 651. A portion of the second connecting body 66 is connected to the second connecting portion 652, and both ends of the second connecting body 66 are spaced apart from the second connecting portion 652 in a direction parallel to the axis of the first winding portion 10 to form a gap 69, for example, the upper left side of the second connecting body 66 is spaced apart from the lower surface of the second connecting portion 652, and the upper right side of the second connecting body 66 is spaced apart from the lower surface of the second connecting portion 652. One end of the connecting plate 76 in a direction parallel to the axis of the first winding portion 10 is plugged into the gap 69, for example, a portion of the upper end of the connecting plate 76 can be plugged into the gap 69, which can not only improve the protection effect, but also increase the freedom of the second cover plate 72. Optionally, in a direction parallel to the axis of the first winding portion 10, a portion of the second connecting portion 652 is located on one side of the mounting portion 40, for example, the second connecting portion 652 is located above the first surface 42, and the second connecting portion 652 and the first surface 42 are spaced apart, which can be used to avoid the bent pin 200. Optionally, in the direction close to the axis of the first winding portion 10, the edge of the second connecting portion 652 has an arc-shaped groove, such as Fig. 9As shown, for example, the inner edge of the second connecting portion 652 has an arc-shaped groove, which can avoid the gear assembly 500 and the like. In addition, the second connecting portion 652 and the blocking portion 50 cooperate to form a space, which can avoid, accommodate, and protect the plug pin 200 in the space. Optionally, in the direction parallel to the axis of the first winding portion 10, one end of the second extension portion 53 is higher than the blocking portion 50, for example, the upper end of the second extension portion 53 is higher than the upper edge of the blocking portion 50, which is conducive to applying a force to the plug pin 200 through the space above the blocking portion 50. Optionally, when the second extension portion 53 is connected to the first connecting body 65, a part of the second connecting portion 652 can overlap the second extension portion 53 to improve the structural stability, connection tightness and convenience, and after the second connecting portion 652 overlaps the second extension portion 53, there is a space between the second connecting portion 652 and the blocking portion 50, which can avoid the installation portion 40 and the bent plug pin 200.

[0161] In some specific embodiments of the present invention, in the axial direction parallel to the first winding portion 10, the other end of the connecting plate 76 is located on the outside of the second connecting body 66, for example, a portion of the lower end of the connecting plate 76 is located on the outside of the second connecting body 66, which can further improve the protection effect.

[0162] According to one embodiment of the present invention, Fig.13 As shown, the crimping protrusion 74 has a plurality of protrusions 741 spaced apart from each other, for example, the crimping protrusion 74 extends in the up-down direction, and the surface of the crimping protrusion 74 includes a plurality of protrusions 741 spaced apart from each other in the up-down direction.
