[0055] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0056] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] The bending process of the pin 200 of the coil assembly according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] like Figures 1 to 14 As shown, the coil assembly according to an embodiment of the present invention includes a motor frame and a pin 200, and the motor frame 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. The first winding part 10 is cylindrical in shape and is used to wind the winding wire. The first flange part 20 is provided at one axial end of the first winding part 10, and the second flange part 30 is provided at the other axial end of the first winding part 10. The mounting part 40 is provided at the outer periphery of the first flange part 20. A first through hole 41 is provided on the mounting part 40. The first through hole 41 is used to mount the pin 200. The blocking part 50 protrudes from the surface of the mounting part 40 away from the second flange part 30 and is located on the side of the first through hole 41 close to the axis of the first winding part 10. The blocking part 50 can prevent the metal beads generated during the metal treatment of the pin 200 from rolling toward the axis of the first winding part 10.

[0059] That is, the coil assembly according to the embodiment of the present invention mainly includes a motor frame and a pin 200 , the motor frame mainly includes a coil frame 100 , and the coil frame 100 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 .

[0060] The first winding portion 10 is cylindrical, for example, a cylindrical member extending in an up-down direction. The first winding portion 10 is used to wind the winding wire, that is, the winding wire can be wound on the first winding portion 10 .

[0061] The first flange 20 is provided at one axial end of the first winding portion 10, and the second flange 30 is provided at the other axial end of the first winding portion 10. For example, the first flange 20 is provided at the upper end of the first winding portion 10, and the second flange 30 is provided at the lower end of the first winding portion 10. The mounting portion 40 is provided at the outer periphery of the first flange 20, for example, approximately one-quarter of the outer periphery of the first flange 20. The mounting portion 40 is provided with at least one first through-hole 41, i.e., a through-hole 41 is provided. This first through-hole 41 can be used to mount the pin 200. Specifically, the pin 200 can be mounted within the first through-hole 41, and a winding wire can be connected to the pin 200 during installation. In this embodiment, the cross-sectional shape of the pin 200 is not limited. For example, the cross-sectional shape of the pin 200 can be square to prevent the winding wire from slipping. Specifically, the pin 200 includes, but is not limited to, a square.

[0062] Furthermore, the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second flange 30 and is located on the side of the first through-hole 41 that is closer 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 bobbin 100 of the present invention is used in a motor, the motor includes a gear assembly 500, at least a portion of which is located on one side of the blocking portion 50. For example, the gear assembly 500 includes multiple meshing gears, at least a portion of which is located on one side of the blocking portion 50. The pin 200 is located on the other side of the blocking portion 50. The blocking portion 50 prevents metal beads generated during metal finishing of the pin 200 from rolling into the gear assembly 500. For example, during tinning of the pin 200, solder beads can be prevented from entering the gear assembly 500, causing jamming or even blocking. This prevents solder beads generated during tinning of the terminal posts of existing motors from splashing into the gearbox. In addition, during assembly, the pin 200 can be wrapped with enameled wire and then tinned to provide protection. The pin 200 is wrapped with an enameled wire connector, and the tinning can ensure that the pin 200 and the enameled wire are electrically connected.

[0063] A method for assembling a coil assembly according to an embodiment of the present invention includes the following steps:

[0064] Install the pin 200 in the first through hole 41, as shown in FIG. Figure 7As 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 within the first through hole 41. The third segment 203 extends out of the first through hole 41 and 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.

[0065] A force is applied to the first segment 201 in a direction from the blocking portion 50 away from the axis of the first winding portion 10 , driving the first segment 201 to bend.

[0066] That is, in a 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 vertical 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 installation, a force can be applied from the inside of the mounting portion 40 through the blocking portion 50 to the upper end of the pin 200, forcing 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 installation, a force can be applied from the inside out through the blocking portion 50 to the upper portion of the pin 200 installed in the first through-hole 41, forcing the upper portion of the pin 200 to bend outward.

[0067] According to one embodiment of the present invention, the number of first through holes 41 and the number of pins 200 are respectively multiple and one-to-one corresponding, and a force is applied to the multiple first segments 201 simultaneously along the direction from the blocking portion 50 toward the axis away from the first winding portion 10. By providing multiple first through holes 41, it is convenient to install multiple pins 200 at the same time, and it is convenient to perform 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 extension direction of the mounting portion 40, it is convenient to control the orderly arrangement of the multiple 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.

[0068] In some specific embodiments of the present invention, Figure 5 As shown, the motor skeleton also 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 cylindrical and is used to wind the winding wire, the third flange portion 302 is provided at one axial end of the second winding portion 301, the fourth flange portion 303 is provided 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 6As shown, an avoidance groove 304 is provided at the connection position between the two to avoid the third section 203.

[0069] The present invention also provides a coil assembly, including a coil assembly prepared by the assembly method of the coil assembly according to any of the above embodiments.

[0070] The present invention also provides an assembly method of a coil assembly, the coil assembly includes a motor frame and a pin 200, 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 in the shape of a column, the first winding portion 10 is used to wind the winding wire, the first flange portion 20 is provided at one axial end of the first winding portion 10, the second flange portion 30 is provided at the other axial end of the first winding portion 10, the mounting portion 40 is provided at the outer periphery of the first flange portion 20, and the mounting portion 40 is provided. The portion 40 is provided with a first through hole 41 for mounting the pin 200. The blocking portion 50 protrudes from the surface of the mounting portion 40 on the side 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. In the direction from the mounting portion 40 to the axis of the first winding portion 10, the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49. 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.

[0071] The assembly method includes the following steps:

[0072] Install the pin 200 in the first through hole 41. 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 toward one side of the second flange 30.

[0073] A force is applied to the first segment 201 from the gap 49 to move away from the blocking portion 50 , driving the first segment 201 to bend.

[0074] That is, in the axial direction from the mounting portion 40 toward 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, force can be applied through the gap 49 to the upper portion of the pin 200 installed in the first through-hole 41, forcing the upper portion of the pin 200 to bend outward. For example, the pin 200 in the first through-hole 41 extends generally in the vertical direction. When the force is applied outward, the pin 200 above the first through-hole 41 bends outward relative to the pin 200 in the first through-hole 41.

[0075] It should be noted that it is possible to satisfy the requirement 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, or it is possible to satisfy the requirement that 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. The above conditions can also be met at the same time. The specific settings can be made according to product design requirements, and the bending methods are diverse.

[0076] According to one embodiment of the present invention, the number of first through holes 41 and the number of pins 200 are respectively multiple and one-to-one corresponding. A force is applied to the multiple first segments 201 from the gap 49 to move 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 pins 200 at the same time, and it is convenient to perform 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 extension direction of the mounting portion 40, it is convenient to control the orderly arrangement of the multiple 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.

[0077] In addition, when there are multiple pins 200, the mounting portion 40 can be made of 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.

[0078] 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 the up and down direction, and the top of the gap 49 is open, so that a force tool can be inserted from above.

[0079] 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, so that a force-applying tool can be inserted through the open position.

[0080] It should be noted that it is possible to satisfy the condition that 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, or it is possible to satisfy the condition that at least one side of the gap 49 is open in the extension direction of the blocking portion 50, or it is possible to satisfy both conditions at the same time, so that the bending method of the pin 200 is diverse and flexible.

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.

[0090] The first winding portion 10 is cylindrical in shape, for example, the first winding portion 10 is a cylindrical member extending in the vertical direction. The first winding portion 10 can be used to wind the winding wire, that is, the winding wire can be wound on the first winding portion 10. The axis of the first winding portion 10 is Figure 3 As shown by the dotted line in .

[0091] The first flange 20 is provided at one axial end of the first winding portion 10, and the second flange 30 is provided at the other axial end of the first winding portion 10. For example, the first flange 20 is provided at the upper end of the first winding portion 10, and the second flange 30 is provided at the lower end of the first winding portion 10. 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-quarter of the outer periphery of the first flange 20. The mounting portion 40 is provided with at least one first through-hole 41, i.e., a through-hole 41 is provided. This first through-hole 41 can be used to mount the pin 200. Specifically, the pin 200 can be mounted in the first through-hole 41, and a winding wire can be connected to the pin 200 during installation. In this embodiment, the cross-sectional shape of the pin 200 is not limited. For example, the cross-sectional shape of the pin 200 can be square to prevent the winding wire from slipping.

[0092] Furthermore, the blocking portion 50 protrudes from the surface of the mounting portion 40 on the side away from the second collar portion 30, and is located on the side of the first through hole 41 that is closer 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.

[0093] And, as Figure 2 As shown, at least a portion of the gear assembly 500 is located on one side of the barrier 50. For example, the gear assembly 500 includes multiple meshing gears, at least some of which are located on one side of the barrier 50. The pins 200 are located on the other side of the barrier 50. The barrier 50 can prevent metal beads generated during metal treatment of the pins 200 from rolling onto the gear assembly 500. For example, when tinning the pins 200, solder beads can be prevented from entering the gear assembly 500 and causing jamming or even blocking.

[0094] Furthermore, at least a portion of the first cover plate 60 is positioned on a side of the mounting portion 40 that is distal from the axis of the first winding portion 10. Specifically, the first cover plate 60 may cover the outside of the mounting portion 40. For example, on a projection plane extending in a vertical direction with a height and a horizontal direction with a width, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It will be appreciated that, in this embodiment, the side proximal to the axis of the first winding portion 10 is the inner side, and the side distal from the axis of the first winding portion 10 is the outer side. A second through-hole 61 is provided in the first cover plate 60. One end of the pin 200 passes through the second through-hole 61 and connects to the lead 400. Specifically, a portion of the pin 200 extends from the first through-hole 41 and then into the second through-hole 61, then passes through the second through-hole 61 and connects to the lead 400. In this embodiment, the first cover 60 shields the mounting portion 40, and also shields the pins 200 and winding wires extending out of the mounting portion 40, thereby improving both aesthetics and safety. The pins 200 can also be positioned by the second through-holes 61. Furthermore, by providing the second through-holes 61 in the first cover 60, one end of the pin 200 passes through the second through-hole 61 and is connected to the lead 400. For example, if one end of the pin 200 passes through the second through-hole 61 and is welded to the lead 400, the shielding of the first cover 60 prevents metal from splashing into the interior of the gear assembly 500 during welding.

[0095] The second cover plate 70 is disposed on a side of the first cover plate 60 away from the mounting portion 40. Specifically, the second cover plate 70 is disposed outside 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 overlaps the orthographic projection of the first cover plate 60. In this embodiment, the second cover plate 70 shields the leads 400 and the connection between the leads 400 and the pins 200, improving aesthetics, structural stability, and safety, and protecting the connection between the leads 400 and the pins 200 and the leads 400 from environmental influences.

[0096] 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 prevent the metal beads generated during the metal processing of the pin 200 from rolling onto 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 jam or get stuck. The first cover plate 60 and the second cover plate 70 can also be used to improve the aesthetics, structural stability and safety.

[0097] According to one embodiment of the present invention, the highest end of the pin 200 is higher than the highest end of the blocking portion 50 in a direction parallel to the axis of the first winding portion 10. For example, in the vertical 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 installation, a force can be applied from the inside of the mounting portion 40 through the blocking portion 50 to the upper end of the pin 200, forcing the upper end of the pin 200 to bend outward. In this embodiment, by restricting the position of the highest end of the pin 200, during installation, a force can be applied from the inside out through the blocking portion 50 to the upper portion of the pin 200 installed in the first through-hole 41, forcing the upper portion of the pin 200 to bend outward.

[0098] In some specific embodiments of the present invention, Figure 3 As shown, in the axial direction from the mounting portion 40 toward 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 gap 49 can apply force to the upper portion of the pin 200 installed in the first through-hole 41, forcing the upper portion of the pin 200 to bend outward. For example, the pin 200 in the first through-hole 41 extends generally in the vertical direction. After the force is applied outward, the pin 200 above the first through-hole 41 bends outward relative to the pin 200 in the first through-hole 41.

[0099] It should be noted that it is possible to satisfy the requirement 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, or it is possible to satisfy the requirement that 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. The above conditions can also be met at the same time. The specific settings can be made according to product design requirements, and the bending methods are diverse.

[0100] 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 are 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. An open groove 48 is provided on the outer side of the mounting portion 40, which is 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, and the angle between the third surface 44 and the second surface 43 is an obtuse angle.

[0101] That is, the outer surface of the mounting portion 40 primarily 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 via the second surface 43. In other words, the first surface 42 and the third surface 44 are indirectly connected, with the second surface 43 being respectively connected to the first surface 42 and the third surface 44. Furthermore, a portion of the first through hole 41 is provided on the first surface 42, and another portion 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.

[0102] In addition, an open slot 48 is provided on the outside of the mounting portion 40, spaced apart from the first through hole 41. A portion of the open slot 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 slot 48 connects 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 pass through the open slot 48 and connect to a portion of the pin 200 extending from the first through hole 41. For example, the upper portion of the pin 200 extends from the upper end of the first through hole 41 and connects to the winding wire. In this embodiment, the provision of the open slot 48 can define the position of the winding wire, prevent the winding wire from interfering with other structures, and improve the efficiency and safety of the winding wire.

[0103] 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.

[0104] 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 through the fourth surface 47 , and a portion of the opening groove 48 is provided on the fourth surface 47 .

[0105] That is, in this embodiment, the outer surface of the mounting portion 40 mainly includes a first surface 42, a second surface 43, a third surface 44, and a fourth surface 47. The fourth surface 47 is connected to the third surface 44 and the first flange portion 20, respectively. The third surface 44 is indirectly connected to the first flange portion 20. The first portion of the opening groove 48 is provided on the first surface 42, the second portion is provided on the second surface 43, the third portion is provided on the third surface 44, and the fourth portion 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.

[0106] In this embodiment, the fourth surface 47 is used to reduce the area required to machine the third surface 44 on the mounting portion 40, facilitating machining. Furthermore, by connecting the opening groove 48 to the fourth surface 47, machining the opening groove 48 on the outer surface of the mounting portion 40 is facilitated and the wall edge of the opening groove 48, which would otherwise rub against the winding wire, is avoided due to the opening groove 48 being too short.

[0107] 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 axial 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 for 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 friction at the edge of the opening groove 48.

[0108] According to one embodiment of the present invention, Figure 8 As shown, 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 escape space 68 to avoid the mounting portion 40. The second connector 66 is provided with a second through hole 61. The third connector 67 has a plurality of first grooves 63. The first grooves 63 are used to limit the lead wires 400. For example, the extension direction of the first grooves 63 is parallel to the axial direction of the first winding portion 10.

[0109] 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. The mounting portion 40 can be avoided through the first avoidance space 68, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoidance space 68.

[0110] The second connector 66 is provided with a second through-hole 61, through which one end of the pin 200 passes and is connected to the lead 400. The third connector 67 is provided with a plurality of first slots 63, each of which extends parallel to the axis of the first winding portion 10. At least a portion of the lead 400 can be mounted within the first slot 63, thereby retaining the lead 400.

[0111] In some specific embodiments of the present invention, in a direction perpendicular to the axis of the first winding portion 10, both sides of the second connector 66 and the third connector 67 are respectively snap-fitted to the second cover plate 70. For example, the left side of the second connector 66 is snap-fitted to the left side of the second cover plate 70, and the right side of the second connector 66 is also snap-fitted to the right side of the second cover plate 70. Similarly, the left side of the third connector 67 is snap-fitted to the left side of the second cover plate 70, and the right side of the third connector 67 is also snap-fitted to 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 connection, expand the range of the connection area, and adopt a symmetrical design to facilitate processing and manufacturing.

[0112] 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 clamped with the second cover plate 70 to improve the strength of the connection. During assembly, by limiting the shape of the clamping structure, the second cover plate 70 can be covered on the outside 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 clamping method, installation and disassembly are convenient. By clamping the two sides separately, it is also beneficial to improve the overall stability.

[0113] According to one embodiment of the present invention, Figure 12 As shown, the inner wall surface of the second cover plate 70 opposite to the first cover plate 60 is provided with: a plurality of second clamping portions 72 and a plurality of pressing protrusions 74.

[0114] 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.

[0115] Specifically, the second cover plate 70 is disposed outside at least a portion of the first cover plate 60. A second clip 72 and a crimping protrusion 74 are provided on the inner side of the second cover plate 70. There are multiple second clips 72, and a second groove 73 is formed between adjacent second clips 72. Alternatively, a second groove 73 is formed between the second clips 72 and the edge of the second cover plate 70. For example, multiple second clips 72 are spaced apart in the left-right direction, with a second groove 73 formed between the leftmost second clip 72 and the left edge of the second cover plate 70, and a second groove 73 between the rearmost second clip 72 and the right edge of the second cover plate 70. In this embodiment, the provision of the second groove 73 allows the connection between the pin 200 and the lead 400 to be mounted in the second groove 73, thereby securing the connection. Furthermore, after the second cover plate 70 is mounted to the first cover plate 60, the crimping protrusion 74 can abut against the lead 400, securing the lead 400. By installing the second cover plate 70 onto the first cover plate 60 , a force can 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 .

[0116] 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.

[0117] That is, the long side of the mounting portion 40 extends along its length, the thick side extends along its thickness, and the tall side extends along its height. The length direction is perpendicular to the axis 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 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.

[0118] 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 and right directions, so as to facilitate the simultaneous installation of multiple pins 200 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 spacing out the multiple first through holes 41 along the length direction, it is beneficial to control the orderly arrangement of the multiple pins 200 on the mounting portion 40, which is beneficial for 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 be made of 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.

[0119] According to one embodiment of the present invention, the blocking portion 50 is a solid, flat plate. The long side of the blocking portion 50 extends in the length direction, and the tall 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 along the length direction. The use of the blocking portion 50 not only expands the range of metal bead blocking but also simultaneously blocks metal bead generated during metal processing of multiple pins 200. Furthermore, the solid, flat plate structure facilitates manufacturing.

[0120] Optionally, the motor further includes a housing, in which a coil skeleton 100 and the like are arranged.

[0121] The coil bobbin 100 of the present application will be described in detail below with reference to specific embodiments.

[0122] The coil bobbin 100 according to the embodiment of the present invention 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 .

[0123] Specifically, the first winding portion 10 is cylindrical in shape and is used to wind the winding wire. The first flange portion 20 is provided at one axial end of the first winding portion 10, and the second flange portion 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 flange portion 20. The mounting portion 40 is provided with a first through hole 41, and the first through hole 41 is used to mount the pin 200. The blocking portion 50 protrudes from the surface of the mounting portion 40 away from the side of 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. The blocking portion 50 can prevent the metal beads generated during the metal processing of the pin 200 from rolling toward the axis of the first winding portion 10.

[0124] In other words, the coil bobbin 100 according to the embodiment of the present invention mainly includes the first winding portion 10 , the first collar portion 20 , the second collar portion 30 , the mounting portion 40 and the blocking portion 50 .

[0125] The first winding portion 10 is cylindrical, for example, a cylindrical member extending in an up-down direction. The first winding portion 10 is used to wind the winding wire, that is, the winding wire can be wound on the first winding portion 10 .

[0126] The first flange 20 is provided at one axial end of the first winding portion 10, and the second flange 30 is provided at the other axial end of the first winding portion 10. For example, the first flange 20 is provided at the upper end of the first winding portion 10, and the second flange 30 is provided at the lower end of the first winding portion 10. 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-quarter of the outer periphery of the first flange 20. The mounting portion 40 is provided with at least one first through-hole 41, i.e., a through-hole 41 is provided. This first through-hole 41 can be used to mount the pin 200. Specifically, the pin 200 can be mounted in the first through-hole 41, and a winding wire can be connected to the pin 200 during installation. In this embodiment, the cross-sectional shape of the pin 200 is not limited. For example, the cross-sectional shape of the pin 200 can be square to prevent the winding wire from slipping.

[0127] Furthermore, the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second flange 30 and is located on the side of the first through-hole 41 that is closer 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 bobbin 100 of the present invention is used in a motor, the motor includes a gear assembly 500, at least a portion of which is located on one side of the blocking portion 50. For example, the gear assembly 500 includes a plurality of meshing gears, at least a portion of which is located on one side of the blocking portion 50. The pin 200 is located on the other side of the blocking portion 50. The blocking portion 50 prevents metal beads generated during metal treatment of the pin 200 from rolling into the gear assembly 500. For example, during tinning of the pin 200, solder beads can be prevented from entering the gear assembly 500, potentially causing the gear assembly 500 to jam or even become stuck, thereby preventing abnormal noise.

[0128] Therefore, according to the coil assembly 100 of the embodiment of the present application, the blocking portion 50 can prevent the metal beads generated during the metal processing 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 jam, get stuck, or make abnormal noises due to tinning.

[0129] 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, 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.

[0130] 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 it is convenient to set up 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, which is also conducive to realizing the arrangement of rows of pins 200.

[0131] 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.

[0132] According to one 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.

[0133] 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 meet all of the above conditions simultaneously. The specific configuration may be based on product design requirements.

[0134] According to one embodiment of the present invention, there are multiple first through holes 41, each of which corresponds to a pin 200, thereby increasing the total number of pins 200. The multiple first through holes 41 are spaced apart along the length of the mounting portion 40. For example, if the length of the mounting portion 40 is the left-right direction, the multiple first through holes 41 are spaced apart along the left-right direction. The edge of the blocking portion 50 extends beyond the outermost first through holes 41. For example, in the left-right direction, the left edge of the blocking portion 50 extends beyond the leftmost first through hole 41, and the right edge of the blocking portion 50 extends beyond the rightmost first through hole 41. This can expand the shielding range, allowing a single blocking portion 50 to provide protection for multiple pins 200 during metallization processing.

[0135] In some specific embodiments of the present invention, the length of the blocking portion 50 along the length direction of the mounting portion 40 is not less than the length of the mounting portion 40. In other words, 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; in another example, in the left-right direction, the length of the blocking portion 50 is greater than the length of the mounting portion 40.

[0136] According to one 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.

[0137] 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, which can be prepared and produced by, for example, integral injection molding to facilitate processing.

[0138] According to one 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, which can be prepared and produced by, for example, integral injection molding to facilitate processing.

[0139] The present invention further provides a coil assembly comprising: a pin 200 and a motor frame, wherein the motor frame comprises the coil frame 100 of any of the aforementioned embodiments, and the pin 200 is mounted within the first through hole 41 of the coil frame 100. Since the coil assembly of the present embodiment comprises the coil frame 100 of any of the aforementioned embodiments, and the coil frame 100 has a protective effect, the coil assembly of the present embodiment has the same effect and is not further described here.

[0140] According to one embodiment of the present invention, a motor frame includes: a first frame and a second frame 300, wherein the first frame is a coil frame 100, and the second frame 300 is connected to the first frame. For example, the first frame is positioned above the second frame 300, and the first frame can be defined as the upper frame, and the second frame 300 as the lower frame. The first frame can be the coil frame 100 of any of the above embodiments. Optionally, the first frame and the second frame 300 can be coaxially arranged.

[0141] The mounting portion 40 according to the embodiment of the present application is described in detail below.

[0142] The mounting portion 40 is provided on the outer periphery of the first flange-shaped portion 20. A first through hole 41 is provided on the mounting portion 40. The first through hole 41 is used to mount 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. An open groove 48 is provided on the outer side of the mounting portion 40, which is 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.

[0143] 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-quarter of the outer periphery of the first flange 20. The mounting portion 40 is provided with at least one first through-hole 41, which is provided through the mounting portion 40. This first through-hole 41 is used to mount the pin 200. Specifically, the pin 200 can be mounted within the first through-hole 41, allowing the winding wire to be connected to the pin 200 during installation. In this embodiment, the cross-sectional shape of the pin 200 is not limited; for example, a square cross-section of the pin 200 can prevent the winding wire from slipping.

[0144] The outer surface of the mounting portion 40 primarily 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 via the second surface 43. In other words, the first surface 42 and the third surface 44 are indirectly connected, with the second surface 43 being connected to the first surface 42 and the third surface 44, respectively. Furthermore, a portion of the first through hole 41 is provided on the first surface 42, and another portion 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.

[0145] An open slot 48 is provided on the outside of the mounting portion 40, which is spaced apart from the first through hole 41. A portion of the open slot 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 slot 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 pass through the open slot 48 and connect to a portion of the pin 200 extending out of the first through hole 41. 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 slot 48, the position of the winding wire can be limited, thereby preventing the winding wire from interfering with other structures, and improving the efficiency and safety of the winding wire.

[0146] 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.

[0147] According to one embodiment of the present invention, the first surface 42 and the second surface 43 are transitionally connected via a first arc surface 45, and / or the second surface 43 and the third surface 44 are transitionally connected via a second arc surface 46. The use of transitional connections further protects the winding wires and allows for smooth routing of the winding wires.

[0148] 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 vertical direction, the second surface 43 is closer to the second flange 30 relative to the first surface 42. In this embodiment, by having the second surface 43 closer to the second flange 30 relative to the first surface 42, the winding wire can enter the open slot 48 in a shorter distance after being wound on the first winding part 10.

[0149] According to one embodiment of the present invention, Figure 4 As shown, the first through hole 41 includes a first hole section 411 and a second hole section 412 .

[0150] Specifically, one end of the first hole segment 411 connects to the first surface 42, the first end of the second hole segment 412 connects to the other end of the first hole segment 411, the second end of the second hole segment 412 connects to the second surface 43, and the third end of the second hole segment 412 connects to the third surface 44. For example, the first through hole 41 includes a first hole segment 411 and a second hole segment 412, which are arranged vertically. The upper end of the first hole segment 411 connects to the first surface 42, the upper end of the second hole segment 412 connects to the lower end of the first hole segment 411, and the lower end of the second hole segment 412 connects to both the second surface 43 and the third surface 44. In this embodiment, because the second hole segment 412 connects 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, while the other end of the pin 200 can bend outward toward the second surface 43 and maintain a certain distance from the third surface 44 to avoid contact with the winding wire passing through the third surface 44.

[0151] In some specific embodiments of the present invention, the coil bobbin 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 that is closer to the axis of the first winding portion 10. The blocking portion 50 is capable of preventing metal beads generated during metal processing of the pins 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 that is away from the second flange 30 and is located on the side of the first through-hole 41 that is closer to the axis of the first winding portion 10.

[0152] The blocking portion 50 protrudes from the surface of the mounting portion 40 on a side away from the second collar portion 30, and is located on a side of the first through hole 41 that is closer 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.

[0153] Furthermore, at least a portion of the gear assembly 500 is located on one side of the barrier 50. For example, the gear assembly 500 includes multiple meshing gears, at least some of which are located on one side of the barrier 50. The pins 200 are located on the other side of the barrier 50. The barrier 50 prevents metal beads generated during metal treatment of the pins 200 from rolling onto the gear assembly 500. For example, when tinning the pins 200, solder beads can be prevented from entering the gear assembly 500 and causing jamming or even blocking.

[0154] 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.

[0155] That is, the long side of the mounting portion 40 extends along its length, the thick side extends along its thickness, and the tall side extends along its height. The length direction is perpendicular to the axis 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 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.

[0156] 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 simultaneous installation of multiple pins 200 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 spacing out the multiple first through holes 41 along the length direction, it is beneficial to control the orderly arrangement of the multiple pins 200 on the mounting portion 40, which is beneficial for 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.

[0157] 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 through the fourth surface 47, and a portion of the opening groove 48 is connected to the fourth surface 47.

[0158] That is, in this embodiment, the outer surface of the mounting portion 40 primarily includes a first surface 42, a second surface 43, a third surface 44, and a fourth surface 47. The fourth surface 47 is connected to the third surface 44 and the first flange portion 20, respectively. The third surface 44 is indirectly connected to the first flange portion 20. The first portion of the opening slot 48 is provided on the first surface 42, the second portion is provided on the second surface 43, the third portion is provided on the third surface 44, and the fourth portion is provided on the fourth surface 47. In other words, the opening slot 48 simultaneously connects the first surface 42, the second surface 43, the third surface 44, and the fourth surface 47. Furthermore, the fourth surface 47 is parallel to the first surface 42, facilitating machining.

[0159] In this embodiment, the fourth surface 47 is used to reduce the area required to machine the third surface 44 on the mounting portion 40, facilitating machining. Furthermore, by connecting the opening groove 48 to the fourth surface 47, machining the opening groove 48 on the outer surface of the mounting portion 40 is facilitated and the wall edge of the opening groove 48, which would otherwise rub against the winding wire, is avoided due to the opening groove 48 being too short.

[0160] 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 closer 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. 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 closer 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 for protecting the winding wire and preventing the winding wire from contacting the pin 200 passing through the first through hole 41 on the third surface 44.

[0161] In some specific embodiments of the present invention, in the thickness direction, the first through-hole 41 on the first surface 42 is closer to the central axis of the first winding portion 10 than the open slot 48 on the first surface 42. For example, the open slot 48 on the first surface 42 extends inward, and the minimum distance between the inner wall of the open slot 48 on the first surface 42 and the central axis of the first winding portion 10 is L3. The minimum distance between the inner wall of the first through-hole 41 on the first surface 42 adjacent to the open slot 48 and the central axis of the first winding portion 10 is L4, where L4 is less than L3. This facilitates connection between the pin 200 extending from the first through-hole 41 on the first surface 42 and the winding wire.

[0162] 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 portion 30 is smaller than the width dimension of the end close to the second flange portion 30. For example, the axial 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 for 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 friction at the edge of the opening groove 48.

[0163] The first cover plate 60 of the present application will be described in detail below with reference to specific embodiments.

[0164] The mounting portion 40 is provided on the outer periphery of the first flange portion 20, and 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. 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 the height direction and are connected by the second surface 43. The second surface 43 is located on one side of the mounting portion 40 in the thickness direction. A plurality of first through holes 41 are provided on the mounting portion 40. The first through holes 41 are used to install the pins 200. The plurality of first through holes 41 are spaced apart and distributed along the length direction. At least a portion of the first cover plate 60 is provided on the mounting portion 40. On the side of the mounting portion 40 away from the axis of the first winding portion 10, the first cover plate 60 has a first avoidance space 68 to avoid the mounting portion 40. The first cover plate 60 includes: a first connector 65, a second connector 66 and a third connector 67. The second connector 66 is provided on the first connector 65 and cooperates with the first connector 65 to form the first avoidance space 68. The second connector 66 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. The third connector 67 has a plurality of first grooves 63. The first grooves 63 are used to limit the lead 400. The second cover plate 70 is provided on the side of the first cover plate 60 away from the axis direction of the first winding portion 10. The second cover plate 70 can shield the lead 400 and the connection portion between the lead 400 and the pin 200.

[0165] In the length direction, two sides of the second connecting body 66 and the third connecting body 67 are respectively engaged with the second cover plate 70 .

[0166] In other words, the long side of the mounting portion 40 extends along its length, the thick side extends along its thickness, and the tall side extends along its height. The length direction is perpendicular to the axis 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 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.

[0167] The outer surface of the mounting portion 40 primarily 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, spaced apart in a direction parallel to the axis of the first winding portion 10 and connected by the second surface 43. In other words, the first surface 42 and the third surface 44 are indirectly connected, 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. Furthermore, a portion of the first through hole 41 is provided on the first surface 42, and another portion 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.

[0168] The mounting portion 40 is provided with a plurality of first through holes 41, that is, the number of first through holes 41 is multiple, and the multiple first through holes 41 are spaced apart along the length direction, for example, spaced apart along the left-right direction, to facilitate the simultaneous installation of multiple pins 200 and to 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 spacing the multiple first through holes 41 along the length direction, it is convenient to control the orderly arrangement of the multiple 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. In addition, when there are multiple pins 200, the mounting portion 40 can be made of 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 pins 200 to prevent short circuits.

[0169] At least a portion of the first cover plate 60 is disposed on a side of the mounting portion 40 that is distal from the axis of the first winding portion 10. Specifically, the first cover plate 60 may cover the outside of the mounting portion 40. For example, on a projection plane extending in a vertical direction with a height along the vertical direction and a width along the horizontal direction, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It will be understood that in this embodiment, the side proximal to the axis of the first winding portion 10 is the inner side, and the side distal from the axis of the first winding portion 10 is the outer side. A second through-hole 61 is defined in the first cover plate 60. One end of the pin 200 passes through the second through-hole 61 and connects to the lead 400. Specifically, a portion of the pin 200 extends from the first through-hole 41 into the second through-hole 61, then passes through the second through-hole 61 and connects to the lead 400. In this embodiment, the first cover 60 shields the mounting portion 40, and also shields the pins 200 and winding wires extending out of the mounting portion 40, thereby improving both aesthetics and safety. The pins 200 can also be positioned by the second through-holes 61. Furthermore, by providing the second through-holes 61 in the first cover 60, one end of the pin 200 passes through the second through-hole 61 and is connected to the lead 400. For example, if one end of the pin 200 passes through the second through-hole 61 and is welded to the lead 400, the shielding of the first cover 60 prevents metal from splashing into the interior of the gear assembly 500 during welding.

[0170] 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. The mounting portion 40 can be avoided through the first avoidance space 68, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoidance space 68.

[0171] The second connector 66 is provided with a second through-hole 61, through which one end of the pin 200 passes and is connected to the lead 400. The third connector 67 is provided with a plurality of first slots 63, each of which extends parallel to the axis of the first winding portion 10. At least a portion of the lead 400 can be mounted within the first slot 63, thereby retaining the lead 400.

[0172] The second cover plate 70 is disposed on the side of the first cover plate 60 that is away from the axis of the first winding portion 10, that is, the second cover plate 70 is disposed on the side of the first cover plate 60 that is away from the mounting portion 40. In other words, the second cover plate 70 is disposed outside 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 overlaps the orthographic projection of the first cover plate 60. In this embodiment, the provision of the second cover plate 70 shields the leads 400 and the connection between the leads 400 and the pins 200, thereby improving aesthetics, structural stability, and safety, and protecting the connection between the leads 400 and the pins 200 and the leads 400 from environmental influences.

[0173] In addition, in the length direction, both sides of the second connector 66 and the third connector 67 are respectively snap-fitted to the second cover plate 70. For example, the left side of the second connector 66 is snap-fitted to the left side of the second cover plate 70, and the right side of the second connector 66 is also snap-fitted to the right side of the second cover plate 70. Similarly, the left side of the third connector 67 is snap-fitted to the left side of the second cover plate 70, and the right side of the third connector 67 is also snap-fitted to 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 connection, expand the range of the connection area, and adopt a symmetrical design to facilitate processing and manufacturing.

[0174] According to one embodiment of the present invention, Figure 9 As shown, in the longitudinal direction, the second connector 66 and the third connector 67 are provided with engaging protrusions 64 on both sides, and engaging grooves 71 are provided on the second cover plate 70 at positions corresponding to the engaging protrusions 64. For example, if the longitudinal direction is the left-right direction, the left and right sides of the second connector 66 are provided with engaging protrusions 64, and the left and right sides of the second cover plate 70 are also provided with engaging grooves 71. The engaging protrusions 64 and engaging grooves 71 are detachably connected, enabling installation and removal of the second cover plate 70 from the first cover plate 60. In this embodiment, the use of the engaging protrusions 64 and engaging grooves 71 facilitates operation and facilitates installation and removal.

[0175] In some specific embodiments of the present invention, the second connector 66 and the third connector 67 are provided with engaging grooves 71 on both sides thereof in the longitudinal direction, and the second cover plate 70 is provided with engaging protrusions 64 at positions corresponding to the engaging grooves 71. For example, the second connector 66 is provided with engaging grooves 71 on both sides thereof, and the second cover plate 70 is provided with engaging protrusions 64 on both sides thereof, to facilitate installation and removal.

[0176] According to one embodiment of the present invention, in the length direction, one of the second connector 66 and the third connector 67 is provided with a snap-fit ​​groove 71 on both sides, and the other is provided with a snap-fit ​​protrusion 64 on both sides. The second cover plate 70 is provided with a snap-fit ​​protrusion 64 at a position corresponding to the snap-fit ​​groove 71, and a snap-fit ​​groove 71 is provided at a position corresponding to the snap-fit ​​protrusion 64. For example, the second connector 66 is provided with a snap-fit ​​groove 71 on both sides, and the third connector 67 is provided with a snap-fit ​​protrusion 64 on both sides; for another example, the second connector 66 is provided with a snap-fit ​​protrusion 64 on both sides, and the third connector 67 is provided with a snap-fit ​​groove 71 on both sides, to facilitate operation.

[0177] It can be seen from the above-mentioned combining methods that the second cover plate 70 and the first cover plate 60 can be connected in various ways.

[0178] In some specific embodiments of the present invention, there are multiple engaging protrusions 64 and engaging grooves 71, each with a one-to-one correspondence. The multiple engaging protrusions 64 are spaced apart in the height direction. For example, of four engaging protrusions 64, two engaging protrusions 64 are positioned near the top and form a group, while two engaging protrusions 64 are positioned near the bottom and form a group. In this embodiment, by limiting the spacing of the multiple engaging protrusions 64, different position limits can be achieved, improving structural stability.

[0179] According to one embodiment of the present invention, the cross-section of the engaging protrusion 64 along the radial direction of the first winding portion 10 is triangular. The outer side surface of the engaging protrusion 64 includes a first side surface, a second side surface 641, and a third side surface 642. The first side surface is connected to the side surface of the second connector 66 or the third connector 67. The second side surface 641 is spaced apart from the first connector 65. The third side surface 642 is connected to the first side surface and the second side surface 641, respectively. The angle between the third side surface 642 and the second side surface 641 is an acute angle. In this embodiment, by defining the shape of the engaging protrusion 64, the second cover plate 70 can be slidably installed along a direction parallel to the axis of the first winding portion 10. In addition, the engaging protrusion 64 with the above-described shape can achieve circumferential positioning of the second cover plate 70.

[0180] 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 separation can avoid the connection between the lead 400 and the pin 200, facilitating the connection between the lead 400 and the pin 200 and the connection operation.

[0181] In the height direction, the plurality of first through-holes 41 correspond one-to-one with the plurality of first slots 63. For example, at least a portion of a first through-hole 41 is located above a first slot 63. After a pin 200 is inserted into a first through-hole 41, its lower end extends out of the first through-hole 41. At least a portion of a lead 400 can be installed in the first slot 63. A lead 400 corresponds to and is connected to a pin 200. In this embodiment, the one-to-one correspondence between the plurality of first through-holes 41 and the plurality of first slots 63 improves structural order.

[0182] It should be noted that the second connector 66 and the third connector 67 can be spaced apart and distributed in the height direction, or the multiple first through holes 41 and the multiple 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.

[0183] According to one embodiment of the present invention, the coil skeleton 100 further includes: a blocking portion 50, which protrudes from a surface of the mounting portion 40 away from the second flange portion 30 and is located on a 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 metal processing of the pin 200 from rolling toward the axis of the first winding portion 10. The blocking portion 50 is detachably connected to the first cover plate 60.

[0184] In some specific embodiments of the present invention, the blocking portion 50 includes a body 51 , a first extending portion 52 , and a second extending portion 53 .

[0185] Specifically, the body 51 is located on the side of the first cover plate 60 that is close to the axis of the first winding portion 10, and is capable of preventing metal beads generated during metal treatment of the pin 200 from rolling toward the axis of the first winding portion 10. For example, the axis of the first winding portion 10 is located on the inner side of the body 51, and the first through-hole 41 is located on the outer side of the body 51. After the pin 200 is installed, the body 51 is located between the axis of the first winding portion 10 and at least a portion of the pin 200. During metal treatment of the pin 200, such as tinning, the body 51 prevents the tin beads from being transported toward the interior of the gear assembly 500, which is close to the axis of the first winding portion 10.

[0186] In the longitudinal direction, one end of the first extension portion 52 is connected to the end of the main body 51, and the other end of the first extension portion 52 is connected to the second extension portion 53. For example, the longitudinal direction is the left-right direction, with the axis closer to the first winding portion 10 being the rear end and the axis farther from the first winding portion 10 being the front end. The front end of the first extension portion 52 is connected to the right end of the main body 51, and the rear end of the first extension portion 52 is connected to the left end of the second extension portion 53. For another example, the front end of the first extension portion 52 is connected to the left end of the main body 51, and the rear end of the first extension portion 52 is connected to the right end of the second extension portion 53. In this embodiment, the second extension portion 53, the first extension portion 52, and the first winding portion 10 can cooperate to form a "J"-shaped member with an opening facing the axis of the first winding portion 10. The first connector 65 has a second relief space 62, and the second extension portion 53 is located in the second relief space 62, which can improve the tightness of the connection, enhance the protective effect, and improve the compactness of the structure. The second extension portion 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 .

[0187] 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, if the axis of the first winding portion 10 is in the vertical direction, the lower end of the first connector 65 contacts the first collar 20. In this embodiment, this not only provides a sealing effect but also provides support for the first connector 65.

[0188] The second cover plate 70 of the present application will be described in detail below with reference to specific embodiments.

[0189] The second cover plate 70 is provided on a side of the first cover plate 60 away from the axial direction of the first winding portion 10 and is detachably connected to the first cover plate 60 . The detachable connection method here includes but is not limited to snap connection, threaded connection, bolt connection, etc.

[0190] 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.

[0191] 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. In other words, the second cover plate 70 is disposed outside the first cover plate 60. For example, on a projection plane extending in the vertical direction with a height along the vertical direction and a width along the horizontal direction, the orthographic projection of the second cover plate 70 overlaps the orthographic projection of the first cover plate 60. In this embodiment, the provision of the second cover plate 70 shields the leads 400 and the connection between the leads 400 and the pins 200, thereby improving aesthetics, structural stability, and safety, and protecting the connection between the leads 400 and the pins 200 and the leads 400 from environmental influences.

[0192] 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.

[0193] In addition, the inner wall surface of the second cover plate 70 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 to install the connection part between the pin 200 and the lead 400, and the crimping protrusion 74 is used to abut the lead after the second cover plate 70 is installed to the first cover plate 60.

[0194] Specifically, the second cover plate 70 is disposed outside at least a portion of the first cover plate 60. A second clip 72 and a crimping protrusion 74 are provided on the inner side of the second cover plate 70. There are multiple second clips 72, and a second groove 73 is formed between adjacent second clips 72. Alternatively, a second groove 73 is formed between the second clips 72 and the edge of the second cover plate 70. For example, multiple second clips 72 are spaced apart in the left-right direction, with a second groove 73 formed between the leftmost second clip 72 and the left edge of the second cover plate 70, and a second groove 73 between the rearmost second clip 72 and the right edge of the second cover plate 70. In this embodiment, the provision of the second groove 73 allows the connection between the pin 200 and the lead 400 to be mounted in the second groove 73, thereby securing the connection. Furthermore, after the second cover plate 70 is mounted to the first cover plate 60, the crimping protrusion 74 can abut against the lead 400, securing the lead 400. By installing the second cover plate 70 onto the first cover plate 60 , a force can 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 .

[0195] 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.

[0196] That is, the long side of the mounting portion 40 extends along its length, the thick side extends along its thickness, and the tall side extends along its height. The length direction is perpendicular to the axis 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 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.

[0197] In some specific embodiments of the present invention, Figure 14 As shown, the second cover plate 70 includes: a baffle 75 and a connecting plate 76. The baffle 75 is located on the side of the first cover plate 60 away from the mounting portion 40. The inner wall of the baffle 75 is provided with a second clamping portion 72 and a crimping protrusion 74. The connecting plates 76 are provided on both sides of the baffle 75 in the longitudinal direction. The connecting plates 76 and the baffle 75 cooperate to form a "door"-like shape. For example, the baffle 75 extends in the vertical direction. At least a portion of the first cover plate 60 is located on the inner side of the baffle 75. The inner wall of the baffle 75 is provided with a second clamping portion 72 and a crimping protrusion 74. The connecting plates 76 are respectively provided on the left and right sides of the baffle 75. The baffle 75 and the two connecting plates 76 cooperate to form a "door"-like structure with an opening facing inward. In addition, the connecting plates 76 are detachably connected to the first cover plate 60. The detachable connection methods here include but are not limited to clamping, threaded connection, bolt connection, etc. In this embodiment, the second engaging portion 72 and the crimping protrusion 74 are provided on the inner wall of the baffle 75, which not only facilitates processing but also facilitates positioning of the lead 400, etc. The connection plate 76 and the baffle 75 are defined to form a "door" shape, facilitating assembly between the second cover 70 and the first cover 60.

[0198] According to one embodiment of the present invention, the second cover plate 70 further includes: a plurality of limiting protrusions 77, which are provided 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 correspond to each other. The lead wire 400 crimped by the crimping protrusion 74 can pass through the limiting groove 78. In this embodiment, the use of the limiting groove 78 not only facilitates the passage of the lead wire 400, but also limits the position of the lead wire 400. At the same time, the limiting protrusion 77 can protect the interior of the second cover plate 70.

[0199] 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 70 being too high due to the need to accommodate the lead 400.

[0200] According to an embodiment of the present invention, the depth of the limiting groove 78 is smaller than the depth of the second groove 73 , so that the lead 400 can be limited while not being easily pulled out of the second groove 73 .

[0201] In some specific embodiments of the present invention, the first cover plate 60 includes a first connector 65 , a second connector 66 and a third connector 67 .

[0202] Specifically, 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. The second connector 66 is provided with a second through hole 61. The third connector 67 has a plurality of first grooves 63. The first grooves 63 are used to limit the lead 400. For example, the extension direction of the first grooves 63 is parallel to the axial direction of the first winding portion 10.

[0203] 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 engaged with the second connector 66 and the third connector 67 respectively.

[0204] 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. The mounting portion 40 can be avoided through the first avoidance space 68, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoidance space 68.

[0205] The second connector 66 is provided with a second through-hole 61, through which one end of the pin 200 passes and is connected to the lead 400. The third connector 67 is provided with a plurality of first slots 63, each of which extends parallel to the axis of the first winding portion 10. At least a portion of the lead 400 can be mounted within the first slot 63, thereby retaining the lead 400.

[0206] Furthermore, when the axis of the first winding portion 10 is in the vertical direction, the second connector 66 and the third connector 67 can be spaced apart from each other in the top-to-bottom direction. Furthermore, a baffle 75 can be disposed opposite the second connector 66 and the third connector 67 in the inside-to-outside direction, thereby protecting the second connector 66, the third connector 67, the lead wire 400, and the like.

[0207] 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.

[0208] According to one embodiment of the present invention, Figure 10 As shown, the first connecting body 65 includes a first connecting portion 651 and a second connecting portion 652 .

[0209] Specifically, the first connection portion 651 is installed on a side of the mounting portion 40 away from the first winding portion 10. 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 on the outside of 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. Figure 11 As shown, the second connecting portion 652 and the first connecting 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 connecting portion 652 extends out of the outer surface of the first connecting portion 651, for example, the outer side of the second connecting portion 652 protrudes from the outer surface of the first connecting 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 and 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 the axial direction parallel to the first winding part 10 is inserted into the gap 69. For example, a part of the upper end of the connecting plate 76 can be inserted into the gap 69, which can not only improve the protection effect, but also increase the freedom limit of the second cover plate 72.

[0210] 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.

[0211] According to one embodiment of the present invention, Figure 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 vertical direction, and the surface of the crimping protrusion 74 includes a plurality of protrusions 741 spaced apart from each other in the vertical direction. In this embodiment, by using a plurality of protrusions 741, the installation stability of the lead 400 can be improved.

[0212] Furthermore, the extension direction of the crimping protrusion 74 is parallel to the axial direction of the first winding portion 10, and the plurality of protrusions 741 are spaced apart along the extension direction of the crimping protrusion 74, thereby improving the stability of the lead 400 in a direction parallel to the axial direction of the first winding portion 10. Alternatively, the axial direction of the lead 400 can be parallel to the axial direction of the first winding portion 10, and the use of the protrusions 741 can prevent the lead 400 from moving in its own axial direction.
