[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] The cover plate 100 for a motor according to an embodiment of this application is described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 5 As shown, the cover plate 100 for a motor according to an embodiment of this application includes: a plate body 10 and a first protrusion 20.

[0036] Specifically, the plate 10 is provided with a through hole 11 for passing through a pin. A first protrusion 20 is provided on the plate 10 and located on one side of the through hole 11. The first protrusion 20 is provided with an open groove 21 with open ends. The open groove 21 is used to pass through a lead wire. One open end of the open groove 21 corresponds to the through hole 11. The inner wall surface of the open groove 21 has a waterproof rib 22.

[0037] In other words, the cover plate 100 according to the embodiment of this application adopts a combination of plate 10 and first protrusion 20, and the plate 10 is provided with through hole 11 for inserting pin.

[0038] The cover plate 100 of this application embodiment can be used in a motor. For example, the motor includes a coil assembly, which includes a frame. The frame mainly includes a winding portion and a blade-shaped portion. The winding portion is cylindrical in shape, for example, a cylindrical member extending in the vertical direction. The winding portion can be used to wind winding wires, that is, the winding wires can be wound around the winding portion. The blade-shaped portion is provided at the outer edge of one axial end of the winding portion.

[0039] A mounting portion may be provided on the outer periphery of the edge-shaped portion. For example, a mounting portion may be provided at approximately one-quarter of the outer periphery of the edge-shaped portion. The mounting portion has at least one through-hole, which can be used to install a pin. In other words, a pin can be installed in the pin hole, and the winding wire can be connected to the pin during installation. In this embodiment, the shape of the pin's cross-section is not limited. For example, the cross-section of the pin may be square to prevent the winding wire from slipping. That is, the pin may include, but is not limited to, a guide pin.

[0040] When the cover plate 100 is applied to a motor, it can be mounted on the outside of the mounting portion. For example, at least a portion of the cover plate 100 can be located on the side of the mounting portion away from the axis of the winding portion, meaning the cover plate 100 can cover the outside of the mounting portion. For instance, on a projection plane extending vertically and horizontally, the orthographic projection of the cover plate 100 covers the orthographic projection of the mounting portion. It is understood that in this embodiment, the side closer to the axis of the winding portion is the inner side, and the side farther from the axis of the winding portion is the outer side.

[0041] The cover plate 100 has a through hole 11. One end of the pin passes through the through hole 11 and connects to the lead wire. Specifically, a portion of the pin extends out of the mounting portion and into the through hole 11, then passes through the through hole 11 and connects to the lead wire. In this embodiment, the cover plate 100 can conceal the mounting portion, as well as the pin extending out of the mounting portion and the winding wire, improving both aesthetics and safety. The through hole 11 also limits the position of the pin. Furthermore, by providing the through hole 11 on the cover plate 100, one end of the pin passes through the through hole 11 and connects to the lead wire; for example, one end of the pin passes through the through hole 11 and is soldered to the lead wire.

[0042] Furthermore, a first protrusion 20 is provided on the plate 10. That is, a first protrusion 20 protruding from the surface of the plate 10 is provided on the outer side of the plate 10 away from the winding portion. The first protrusion 20 is located on one side of the through hole 11, for example, on one side of the end of the through hole 11. An opening groove 21 is provided on the first protrusion 20. The opening groove 21 has two open ends, that is, both ends of the opening groove 21 are open in the length direction of the opening groove 21, and the opening groove 21 is also open on the side away from the winding portion. One open end of the opening groove 21 corresponds to the through hole 11. After the pin extends out of the through hole 11, it can be connected to the lead wire passing through the opening groove 21. For example, one end of the lead wire extends out of one open end of the opening groove 21 and is soldered to the pin extending out of the through hole 11.

[0043] In addition, the inner wall of the opening groove 21 has a waterproof rib 22, which can play a waterproof role and prevent external water from flowing into the cover plate 100 along the lead wire, affecting the connection between the pin and the lead wire, the operation of the motor, the life of the pin, etc.

[0044] Therefore, the cover plate 100 for the motor according to the embodiment of this application adopts a combination of plate 10 and first protrusion 20. An opening groove 21 is provided on the outer surface of the first protrusion 20, and a waterproof rib 22 is provided on the inner wall of the opening groove 21, which can achieve a waterproof effect.

[0045] According to one embodiment of this application, there are multiple through holes 11 and multiple opening slots 21, with each through hole 11 and opening slot 21 corresponding one-to-one. For example, there are five through holes 11, spaced apart horizontally, and five opening slots 21, also spaced apart horizontally. In this embodiment, by using multiple through holes 11 and multiple opening slots 21, the number of pins can be increased.

[0046] In some specific embodiments of this application, a through hole 11 and an opening slot 21 are spaced apart and positioned correspondingly along the arrangement direction from the two open ends of the opening slot 21. For example, along the vertical direction, a through hole 11 is located directly above an opening slot 21, which can reduce the difficulty of connecting the pins and leads and improve the reliability of the connection.

[0047] According to one embodiment of this application, the width of the waterproof rib 22 is less than the length of the opening slot 21 along the arrangement direction from the two open ends of the opening slot 21. For example, the width of the waterproof rib 22 is less than the length of the opening slot 21 along the vertical direction, and the width direction of the waterproof rib 22 does not extend beyond the opening slot 21, which facilitates the installation of the waterproof rib 22, facilitates the passage of the lead wire, and improves the appearance.

[0048] In some specific embodiments of this application, there are multiple waterproof ribs 22, which are spaced apart along the arrangement direction from the two open ends of the opening groove 21. For example, there are three waterproof ribs 22 in one opening groove 21, and the opening groove 21 extends vertically along its length. In this embodiment, by using multiple waterproof ribs 22, the waterproofing effect can be improved.

[0049] According to one embodiment of this application, the waterproof rib 22 is tightly fitted to the inner wall of the opening groove 21. For example, the lower wall of the waterproof rib 22 is fitted to the inner wall of the opening groove 21, which can further improve the waterproof effect and the waterproof rib 22 is not easy to shift.

[0050] In some specific embodiments of this application, the shape of the waterproof rib 22 is consistent with the inner contour shape of the opening groove 21, which can improve the waterproof effect and facilitate the installation of the waterproof rib 22.

[0051] According to one embodiment of this application, the waterproof reinforcement 22 includes two straight segments 221 and one arc-shaped segment 222. One end of one straight segment 221 is connected to one end of the arc-shaped segment 222, and one end of the other straight segment 221 is connected to the other end of the arc-shaped segment 222. The two straight segments 221 and the arc-shaped segment 222 form a U-shaped component. For example, the two straight segments 221 are spaced apart in the horizontal direction, and each straight segment 221 extends in the front-to-back direction. The arc-shaped segment 222 is connected at both ends to the rear end of one straight segment 221. Existing lead wires often have a circular cross-section. In this embodiment, by using a U-shaped waterproof reinforcement 22, the contact area between the waterproof reinforcement 22 and the lead wire is increased, further improving the waterproofing effect.

[0052] In some specific embodiments of this application, the cover plate 100 for the motor further includes: a second protrusion 30, which is disposed on the plate body 10 and spaced apart from the first protrusion 20, and located on one side of the plate body 10 with the first protrusion 20. The second protrusion 30 cooperates with the other side of the plate body 10 to form a receiving space 40 with an opening. The plate body 10 is provided with a groove 12, one end of which extends toward the direction of the first protrusion 20, and the other end of which extends toward the direction of the second protrusion 30 and communicates with the through hole 11.

[0053] In other words, a second protrusion 30 is also provided on the plate 10. The inner side of the plate 10, that is, the side near the winding portion, and the inner side of the second protrusion 30 cooperate to form a receiving space 40, which can accommodate the mounting portion, etc. A groove 12 is also provided on the plate 10. One end of the groove 12 faces the first protrusion 20, and the other end of the groove 12 faces the second protrusion 30. For example, the groove 12 extends in the vertical direction and is a straight groove. The upper end of the groove 12 communicates with the through hole 11, and the lower end of the groove 12 extends towards the first protrusion 20. In this embodiment, by providing the second protrusion 30, the mounting portion, etc., can be accommodated. By using the groove 12, it is convenient to open the through hole 11 and to guide the pin direction.

[0054] Optionally, the waterproof rib 22 and the first protrusion 20 can be integrated as one piece, or the waterproof rib 22 can be separately provided on the first protrusion 20, allowing for flexible installation methods.

[0055] Optionally, the first protrusion 20 has a first end face 23 facing the second protrusion 30, and the first end face 23 faces the pin direction. The first protrusion 20 has a second end face 24 on the side away from the winding portion. The first end face 23 and the second end face 24 are connected by a third end face 25. The third end face 25 is inclined relative to the first end face 23 and the second end face 24 respectively, which serves as a transition. For example, the first end face 23 extends in the front-back direction, the second end face 24 extends in the up-down direction, the rear end of the third end face 25 is connected to the upper end of the first end face 23, and the front end of the third end face 25 is connected to the second end face 24. The rear end of the third end face 25 is higher than the front end of the third end face 25. On the one hand, this can increase the environmental space at the pin and lead connection position. On the other hand, it can prevent the sharp corner caused by the direct connection of the first end face 23 and the second end face 24. Furthermore, it is also beneficial to open the groove 12.

[0056] Optionally, a portion of the through hole 11 is formed on the end face of the second protrusion 30 facing the first protrusion 20, and another portion is formed on the plate 10 between the first protrusion 20 and the second protrusion 30, to facilitate the bending of the pin.

[0057] This application also provides a cover plate assembly, including: a cover plate 100 and an outer plate. The cover plate 100 is the cover plate 100 of any of the above embodiments. The outer plate is disposed on the outside of the cover plate 100 and is detachably connected to the cover plate 100. A lead wire is located between the outer plate and the cover plate 100. For example, the outer plate is disposed on the side of the cover plate 100 away from the mounting portion. That is, the outer plate is disposed on the outside of the cover plate 100. For example, on a projection surface that extends vertically and horizontally, the orthographic projection of the outer plate covers the orthographic projection of the cover plate 100.

[0058] In other words, the outer plate can be placed on the side of the cover plate 100 away from the winding part, which can cover the connection position of the lead wire and the pin, as well as the exposed lead wire and the pin, and can play a protective role, such as waterproofing and dustproofing.

[0059] This application also provides a motor, including a coil assembly and a cover plate assembly. The coil assembly includes a pin and a frame. The cover plate assembly is any of the cover plate assemblies described above. The pin passes through the cover plate 100 and is connected to a lead wire.
