Description

Technical Field

[0001] The present application relates to the field of mobile terminal technology, and in particular to a motor and electronic equipment. Background Art

[0002] With the development of technology, the use of mobile devices such as mobile phones is becoming increasingly widespread, and taking photos and videos has become one of the essential functions of mobile devices. Currently, to meet the requirements of camera modules for autofocus and anti-shake, the camera module includes a motor, which is provided with a top cover and a bottom plate. The bottom plate is installed with a connecting wire. When the motor is in operation, the connecting wire is in a taut state, and the motor applies force to the lens through the connecting wire to achieve focusing and anti-shake. When the motor stops working, the connecting wire is de-energized and returns to a relaxed state. Due to the installation gap between the top cover and the bottom plate, when the motor moves, the connecting wire will swing relative to the bottom plate, increasing the risk of the connecting wire getting stuck in the installation gap and reducing the operating stability of the motor. Summary of the Invention

[0003] The present application provides a motor and an electronic device, which can reduce the risk of connecting wires getting stuck in installation gaps and improve the working stability of the motor.

[0004] In a first aspect, the present application provides a motor, comprising:

[0005] base;

[0006] Upper cover, which is fixedly connected to the base;

[0007] The carrier is installed on the base and is used to install the lens;

[0008] A connecting wire, one end of which is connected to the base and the other end is connected to the carrier, and the connecting wire can drive the carrier to move relative to the base;

[0009] Among them, one of the upper cover and the base is provided with a protrusion, and the other is provided with a recessed portion. When the upper cover is connected to the base, the protrusion can cooperate with the recessed portion to fill the installation gap between the upper cover and the base.

[0010] In the present application, the raised portion cooperates with the recessed portion when the upper cover and the base are installed, that is, at least part of the installation gap between the upper cover and the base is filled by the raised portion. When the motor is not working and when the connecting wire shakes relative to the base, the connecting wire can contact the raised portion, thereby reducing the risk of the connecting wire being stuck in the installation gap between the base and the upper cover, thereby improving the stability of the motor operation.

[0011] In a possible design, the raised portion is provided on each peripheral wall of the upper cover or the base, the recessed portion is provided on each peripheral wall of the base or the upper cover, and the raised portion and the recessed portion are provided below the connecting line.

[0012] In the present application, the raised portions are arranged on the peripheral walls of the upper cover or the base, and the recessed portions are arranged on the peripheral walls of the base or the upper cover, so that multiple connecting wires can contact the raised portions when they are in a relaxed state, thereby improving the stability of the connecting wires; the raised portions and the recessed portions are arranged below the connecting wires, which can facilitate the contact between the connecting wires and the raised portions, thereby further reducing the risk of the connecting wires in a relaxed state being stuck between the upper cover and the base.

[0013] In a possible design, the number of protrusions on each peripheral wall of the upper cover or the base is at least two, and the number of recessed portions on each peripheral wall of the base or the upper cover is at least two.

[0014] In the present application, the segmented design of the raised portion (i.e., each peripheral wall of the upper cover or the base includes at least two spaced-apart raised portions) can reduce the size of the raised portion, thereby reducing the production cost of the raised portion; at the same time, it reduces the risk of inaccurate installation of the upper cover and the base due to interference between the raised portion and the upper cover, thereby improving the accuracy of installation of the upper cover and the base.

[0015] In a possible design, the motor further includes a mounting member, and the connecting wire is connected to the carrier and the base via the mounting member;

[0016] Each peripheral wall of the base is provided with two notches, and at least a portion of the mounting member is located in the corresponding notches;

[0017] The raised portion or the recessed portion is located between the two notches and is close to the notches.

[0018] In this application, each peripheral wall of the base is provided with two notches, which facilitates installation of the mounting member and reduces the risk of damage caused by interference with the base when the mounting member is installed, thereby extending the service life of the mounting member. The raised portion or recessed portion is located between the two notches and is close to the notches. With a smaller number of raised portions and recessed portions, the risk of the connecting wire being caught in the installation gap between the upper cover and the base when in a loose state is reduced, and the structural complexity of the motor is reduced.

[0019] In a possible design, the notch has a first side wall, and a distance h1 between the protrusion or the recess and the first side wall satisfies: 0 mm ≤ h1 ≤ 1 mm.

[0020] In the present application, 0mm≤h1≤1mm can reduce the risk that the distance between the protrusion or recessed portion and the first side wall is too large, resulting in the connecting wire being unable to contact the protrusion and being stuck in the installation gap between the base and the upper cover, thereby increasing the stability of the contact between the connecting wire and the protrusion. At the same time, it can increase the strength of the protrusion or recessed portion, thereby extending the service life of the protrusion or recessed portion, and further extending the service life of the motor.

[0021] In a possible design, the protruding part extends in a direction parallel to the bottom surface of the base.

[0022] In the application, the protruding part extends in a direction parallel to the bottom surface of the base, so that when the upper cover is mounted on the base, the protruding part can cooperate with the recessed part to fill the gap between the upper cover and the base, reducing the risk that the connecting line will be clamped into the gap between the upper cover and the base when the protruding part is above the base, thereby improving the stability of the protruding part.

[0023] In a possible design, the length h2 of the protruding part extending in a direction parallel to the bottom surface of the base satisfies: 0.5mm≤h2≤2mm.

[0024] In the application, 0.5mm≤h2≤2mm, which can reduce the risk that the protruding part cannot fill the mounting gap of the base and the upper cover due to the small length of the protruding part extending in a direction parallel to the bottom surface of the base, thereby reducing the risk that the connecting line will be clamped into the mounting gap of the base and the upper cover, while increasing the strength of the protruding part, prolonging the service life of the protruding part, and reducing the size of the protruding part and the production cost.

[0025] In a possible design, the profile of the protruding part and the recessed part is arc-shaped.

[0026] In the application, the profile of the protruding part and the recessed part is arc-shaped, which can facilitate the processing of the protruding part and the recessed part, reduce the production cost of the protruding part and the recessed part, while reducing the risk of safety problems caused by sharp corners in the profile of the protruding part and the recessed part, thereby improving the use safety of the protruding part and the recessed part.

[0027] In a possible design, the protruding part is fixedly connected or integrally formed with the base or the upper cover.

[0028] In the application, the protruding part is fixedly connected or integrally formed with the base or the upper cover, thereby increasing the strength of the protruding part, prolonging the service life of the protruding part, and further prolonging the service life of the motor.

[0029] In a possible design, the number of connecting lines is at least four.

[0030] In the application, the number of connecting lines is at least four, so that the connecting lines can control the movement of the carrier in different directions, thereby improving the use performance of the motor and increasing the application range of the motor.

[0031] In a possible design, at least two connecting lines are arranged on each of the four side surfaces of the motor.

[0032] In the thickness direction of the motor, the connecting lines are arranged obliquely, and the oblique directions of the two connecting lines on the same side surface of the motor are opposite.

[0033] In this application, connecting wires are provided on all four sides of the motor. These wires can exert symmetrical forces on the carrier, resulting in balanced forces acting on the carrier and increasing the stability of the carrier's motion. The connecting wires are arranged at an angle, with two connecting wires on the same side of the motor tilted in opposite directions. This can increase the direction of the force exerted by the connecting wires on the carrier, thereby increasing the direction and trajectory of the carrier's motion relative to the base, thereby improving the motor's operating performance and enhancing the user experience.

[0034] In one possible design, the connecting wire is a shape memory alloy wire.

[0035] In the present application, the connecting wire is a shape memory alloy wire, which can utilize the deformation of the shape memory alloy wire when the power-on state changes to drive the movement of objects such as lens elements, thereby simplifying the structure of the connecting wire and reducing production costs.

[0036] A second aspect of the present application provides an electronic device, which includes a motor, and the motor is the motor described in any one of the above items.

[0037] In this application, the electronic device is provided with a motor, which controls the movement of the lens to achieve lens focus or anti-shake, thereby improving the performance of the electronic device, increasing the scope of application of the electronic device, and further improving the user experience.

[0038] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate embodiments consistent with the present application and, together with the description, further serve to explain the principles of the application. DETAILED DESCRIPTION

[0086] For better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below in combination with the drawings.

[0087] In a specific embodiment, the present application is further described in detail below through specific embodiments and in combination with the drawings.

[0088] As Figures 1-4As shown, the motor includes a housing 1' and a lower cover 2', which are fixedly connected. A lens carrier 3' is mounted on the lower cover 2', and the lens carrier 3' is used to mount the lens. The lower cover 2' is also provided with a plurality of wires 21', and the ends of the wires 21' are respectively connected to the lower cover 2' and the lens carrier 3' via connecting structures 22', so that the wires 21' drive the lens carrier 3' to move relative to the lower cover 2', thereby driving the movement of the lens mounted on the lens carrier 3'. Figure 2 As shown, when the motor is working, the wire 21' is energized and in a taut state, so that the wire 21' generates a force on the lens carrier 3', thereby driving the lens carrier 3' to move relative to the lower cover 2', so as to achieve the purpose of automatic focus or anti-shake of the lens; Figure 3 As shown, when the motor stops working, the wire 21′ is powered off and is in a relaxed state. When the motor moves, the wire 21′ can swing relative to the lower cover 2′. In order to facilitate the installation of the shell 1′ and the lower cover 2′, there is a gap 11′ after the shell 1′ and the lower cover 2′ are fixedly connected. Therefore, when the wire 21′ swings relative to the lower cover 2′, there is a high risk that the wire 21′ is stuck in the gap 11′. If the wire 21′ is stuck in the gap 11′, when the motor starts working, the wire 21′ cannot reach a taut state, so that the wire 21′ cannot generate a force on the lens carrier 3′, thereby resulting in poor working stability of the motor.

[0089] In order to solve the above problems, the first aspect of the embodiment of the present application provides a motor, such as Figures 5-18 As shown, the motor includes: a base 2; an upper cover 1, which is fixedly connected to the base 2; a carrier 3, which is installed on the base 2, and a lens (not shown in the figure) is installed on the carrier 3; a connecting wire 21 is provided on the base 2, one end of the connecting wire 21 is connected to the base 2, and the other end is connected to the carrier 3, and the connecting wire 21 can drive the carrier 3 to move relative to the base 2.

[0090] Among them, the connecting wire 21 is a shape memory alloy wire. The shape memory alloy wire can undergo phase change when the temperature changes, thereby changing the stress state. At low temperatures, the shape memory alloy wire is in the martensite phase; when the temperature rises, the shape memory alloy wire transforms from the martensite phase to the austenite phase and deforms and shrinks. Therefore, an electric current can be passed through the shape memory alloy wire, and the heating effect of the electric current can be used to heat the shape memory alloy wire, thereby achieving the contraction deformation of the shape memory alloy wire. When no current is passed through the shape memory alloy wire, the shape memory alloy wire can return to its original state. Therefore, the connecting wire 21 is a shape memory alloy wire, which can use the deformation of the shape memory alloy wire when the power state changes to drive the movement of objects such as lens elements, thereby simplifying the structure of the connecting wire 21 and reducing production costs.

[0091] The number of the connecting lines 21 is at least four, so that the connecting lines 21 can control the carrier 3 to move in different directions, thereby improving the performance of the motor and increasing the scope of application of the motor.

[0092] Specifically, if Figure 6 、 Figure 7 and Figure 14 As shown, at least two connecting lines 21 are provided on the four side surfaces of the motor. The connecting lines 21 are tilted along the thickness direction of the motor, and the two connecting lines 21 located on the same side of the motor have opposite tilt directions.

[0093] In this embodiment, connecting wires 21 are provided on all four sides of the motor, further increasing the direction of the forces acting on the carrier 3 through the connecting wires 21, thereby further improving the motor's performance. Furthermore, the connecting wires 21 can exert symmetrical forces on the carrier 3, resulting in balanced forces acting on the carrier 3 and increasing the stability of the carrier's movement. The connecting wires 21 are arranged at an angle, with the two connecting wires 21 on the same side of the motor tilted in opposite directions. This increases the direction of the forces acting on the carrier 3 through the connecting wires 21, thereby increasing the direction and trajectory of the carrier's movement relative to the base 2, thereby improving the motor's performance and enhancing the user experience.

[0094] Specifically, if Figures 6-8 As shown, the motor is provided with a mounting member 22, which includes a first mounting member 221 and a second mounting member 222, and the two ends of the connecting line 21 are respectively connected to the first mounting member 221 and the second mounting member 222; the base 2 includes a main body 23 and a first mounting member 24, and the carrier 3 is provided with a second mounting member 31, the first mounting member 221 is installed on the first mounting member 24, and the second mounting member 222 is installed on the second mounting member 31, so as to realize that the two ends of the connecting line 21 are respectively connected to the base 2 and the carrier 3.

[0095] In this embodiment, the first mounting member 221 and the second mounting member 222 are mounted on the base 2 and the carrier 3, respectively. The ends of the connecting wire 21 are connected to the first mounting member 221 and the second mounting member 222, respectively. This simplifies the installation structure of the connecting wire 21 by connecting one end to the base 2 via the first mounting member 221 and the other end to the carrier 3 via the second mounting member 222. This simplifies the installation structure of the connecting wire 21 and reduces production costs. The first mounting member 221 and the second mounting member 222 are mounted on the first mounting portion 24 and the second mounting portion 31, respectively, facilitating installation of the mounting member 22. This simplifies the installation structure of the mounting member 22 and further reduces production costs.

[0096] More specifically, if Figure 6 and Figure 7As shown, the first mounting portion 24 and the second mounting portion 31 have two intersecting side surfaces, and the first mounting member 221 and the second mounting member 222 are respectively mounted on the side surfaces of the first mounting portion 24 and the second mounting portion 31; the motor further includes a first connecting member 5, which is mounted on the carrier 3, and the first connecting member 5 is used to connect the adjacent second mounting member 222; the motor is further provided with a second connecting member 25, which is mounted on the base 2, and the first connecting member 5 and the first mounting member 221 mounted on the first mounting portion 24 are respectively connected to the second connecting member 25.

[0097] In this embodiment, since connecting wires 21 are provided on all four sides of the motor, the first mounting member 221 and the second mounting member 222 are respectively mounted on the sides of the first mounting portion 24 and the second mounting portion 31, facilitating the installation of the connecting wires 21 on each side. The first connector 5 is electrically connected to the adjacent second mounting member 222. The second mounting member 222 and the first mounting member 221 are electrically connected via the connecting wire 21. The first mounting member 221 and the first connector 5 are electrically connected to the second connector 25, respectively. Therefore, when the other end of the second connector 25 is connected to a power source or other electronic component, the power source or other electronic component, the second connector 25, the first mounting member 221, the connecting wire 21, the second mounting member 222, and the first connector 5 form a closed loop, thereby facilitating the control of the power on and off of the multiple connecting wires 21, reducing the risk of the connecting wires 21 failing to properly power on or off, thereby improving the operational stability of the connecting wires 21 and the stability of the motor.

[0098] The material of the mounting member 22 is conductive, and the first connecting member 5 may be a spring or other conductive parts, so that the connecting wires 21 on the adjacent two sides are connected to the first connecting member 5 through the mounting member 22 .

[0099] like Figure 9 and Figure 10As shown, the second connector 25 includes a first connector 251, a second connector 252, and a third connector 253. One end of the first connector 251 is connected to the first mounting member 221. The first mounting member 221 and the second mounting member 222 are connected by a connecting wire 21. Adjacent second mounting members 222 are connected by a first connector 5. One end of the second connector 252 is connected to the first connector 5, and one end of the third connector 253 is connected to the first mounting member 221 on the other side. The other ends of the first, second, and third connectors 251, 252, and 253 all extend out of the motor to connect to the outside world. The provision of the first, second, and third connectors 251, 252, and 253 reduces the risk of circuit confusion, thereby simplifying the circuit and improving the safety of the motor. Furthermore, the user can control the operation of the connecting wires 21 on different sides by controlling the first, second, or third connectors 251, 252, 253 to connect to the circuit, thereby controlling different movement trajectories of the lens to achieve zoom or anti-shake effects, thereby improving the performance of the motor.

[0100] Specifically, if Figure 7 As shown, when the four connecting wires 21 installed on the two opposite sides of the motor are all connected to power, the connecting wires 21 generate a force perpendicular to the axis of the carrier 3 on the carrier 3, so that the carrier 3 can swing around the axis of the carrier 3, thereby playing a role in lens anti-shake; when the connecting wire 21 connected to the bottom end of the second mounting member 222 is connected to power, the connecting wire 21 generates an upward force parallel to the axis of the carrier 3 on the carrier 3, so that the carrier 3 moves upward relative to the base 2; when the connecting wire 21 connected to the top end of the second mounting member 222 is connected to power, the connecting wire 21 generates a downward force parallel to the axis of the carrier 3 on the carrier 3, so that the carrier 3 moves downward relative to the base 2, thereby playing a role in zooming.

[0101] Specifically, if Figure 5 、 Figure 6 、 Figure 13 and Figure 14 As shown, the motor further includes a bottom plate 4 , and the base 2 and the upper cover 1 are both fixedly connected to the bottom plate 4 .

[0102] In this embodiment, a bottom plate 4 is provided, and the base 2 and the upper cover 1 are fixedly connected to the bottom plate 4, thereby increasing the stability of the installation of the base 2 and the upper cover 1. At the same time, it facilitates the connection between the motor and other parts, thereby simplifying the structure of the installation of the motor and other parts, and thus reducing costs.

[0103] The base 2 and the bottom plate 4 are bonded to simplify the connection between the base 2 and the bottom plate 4 ; the upper cover 1 and the bottom plate 4 are welded to increase the stability of the connection between the upper cover 1 and the bottom plate 4 .

[0104] Among them, one of the upper cover 1 and the base 2 is provided with a protrusion 6, and the other is provided with a recessed portion 7. When the upper cover 1 is connected to the base 2, the protrusion 6 can cooperate with the recessed portion 7.

[0105] In this embodiment, if Figure 12 and Figure 17 As shown, when the upper cover 1 and the base 2 are installed, the raised portion 6 cooperates with the recessed portion 7, that is, at least part of the installation gap between the upper cover 1 and the base 2 is filled by the raised portion 6. When the motor is not working and when the connecting wire 21 shakes relative to the base 2, the connecting wire 21 can contact the raised portion 6, thereby reducing the risk of the connecting wire 21 being stuck in the installation gap between the base 2 and the upper cover 1. When the motor is working, the connecting wire 21 can reach a taut state, thereby improving the working stability of the connecting wire 21 and the working stability of the motor; at the same time, it reduces the risk of the connecting wire 21 being stuck in the installation gap and being damaged, thereby extending the service life of the connecting wire 21 and thereby extending the service life of the motor.

[0106] Among them, the upper cover 1 and the base 2 are fixed by bonding, which ensures the connection stability of the upper cover 1 and the base 2 while simplifying the connection method of the upper cover 1 and the base 2, thereby reducing the structure of the upper cover 1 and the base 2 and reducing production costs.

[0107] More specifically, the raised portions 6 are provided on each peripheral wall of the upper cover 1 or base 2, and the recessed portions 7 are provided on each peripheral wall of the base 2 or upper cover 1. If the upper cover 1 and base 2 are square, the raised portions 6 are provided on the four peripheral side walls of the upper cover 1 or base 2, and the recessed portions 7 are provided on the four peripheral side walls of the base 2 or upper cover 1. Furthermore, the raised portions 6 and recessed portions 7 are provided below the connecting line 21.

[0108] In this embodiment, matching protrusions 6 or recesses 7 are provided on each side wall of the upper cover 1 or the base 2, so that multiple connecting wires 21 can contact the protrusions 6 when they are in a relaxed state, thereby improving the working stability of the connecting wires 21; at the same time, when the connecting wires 21 are in a relaxed state after being powered off, the connecting wires 21 droop downward under the action of their own gravity. At this time, the protrusions 6 and the recesses 7 are arranged below the connecting wires 21, which can facilitate the contact between the connecting wires 21 and the protrusions 6, thereby further reducing the risk of the connecting wires 21 in a relaxed state being stuck between the upper cover 1 and the base 2.

[0109] More specifically, if Figure 9 、 Figure 10 、 Figure 15 and Figure 16 As shown, the number of the protrusions 6 on each peripheral wall of the upper cover 1 or the base 2 is at least two, and the number of the recessed parts 7 on each peripheral wall of the base 2 or the upper cover 1 is at least two.

[0110] In this embodiment, the raised portion 6 is designed in sections (i.e., each peripheral wall of the upper cover 1 or the base 2 includes at least two raised portions 6 spaced apart), which can reduce the size of the raised portion 6, thereby reducing the production cost of the raised portion 6; at the same time, it reduces the risk of the raised portion 6 interfering with the upper cover 1, resulting in inaccurate installation of the upper cover 1 and the base 2, thereby improving the accuracy of the installation of the upper cover 1 and the base 2. In addition, if Figure 7 As shown, when each side of the upper cover 1 and the base 2 in the motor has two connecting wires 21, there is a risk that the two connecting wires 21 will be stuck in the installation gap between the upper cover 1 and the base 2 in a relaxed state. Therefore, when at least two matching protrusions 6 and recesses 7 are provided on each peripheral wall of the upper cover 1 or the base 2, the risk of the two connecting wires 21 being stuck in the installation gap between the upper cover 1 and the base 2 in a relaxed state can be reduced.

[0111] Among them, such as Figure 11 、 Figure 12 and Figure 16 As shown, each peripheral wall of the base 2 is provided with two notches 231 , and at least a portion of the mounting member 22 is located in the corresponding notch 231 ; the protrusion 6 or the recess 7 is located between the two notches 231 and close to the notch 231 .

[0112] In this embodiment, each peripheral wall of the base 2 is provided with two notches 231, which can facilitate the installation of the mounting member 22 and reduce the risk of the mounting member 22 interfering with the base when installed on the base 2 and being damaged, thereby extending the service life of the mounting member 22. Figure 7 As shown, each side of the motor is provided with a pair of connecting wires 21, and the connecting wires 21 form a certain angle, that is, the connecting wires 21 form an angle with the horizontal plane. Therefore, the two ends of the connecting wires 21 are distributed vertically along the height direction of the motor, so that one end of the connecting wire 21 is close to the notch 231 and the other end is away from the notch 231. When the connecting wires 21 are in a relaxed state, the connecting wires 21 bend downward under the action of their own weight. That is, the end of the connecting wire 21 close to the notch 231 is most likely to get stuck in the installation gap between the base 2 and the upper cover 1. Therefore, the protrusion 6 or the recessed portion 7 is located between the two notches 231 and close to the notch 231. The smaller number of protrusions 6 and recessed portions 7 can reduce the risk of the connecting wire 21 getting stuck in the installation gap between the upper cover 1 and the base 2 when in a relaxed state, and reduce the structural complexity of the motor.

[0113] Among them, such as Figure 16 As shown, the notch 231 has a first side wall 231 a , and a distance h1 between the protrusion 6 or the recess 7 and the first side wall 231 a satisfies: 0 mm ≤ h1 ≤ 1 mm.

[0114] In this embodiment, when 0mm≤h1≤1mm, the risk that the distance between the protrusion 6 or the recessed portion 7 and the first side wall 231a is too large, resulting in the connection line 21 being unable to contact the protrusion 6 and being stuck in the installation gap between the base 2 and the upper cover 1, can be reduced. At the same time, the risk that the distance between the protrusion 6 or the recessed portion 7 and the first side wall 231a is too small, resulting in the protrusion 6 or the recessed portion 7 being weak and being damaged can be reduced. Therefore, 0mm≤h1≤1mm can increase the stability of the contact between the connection line 21 and the protrusion 6. At the same time, it can increase the strength of the protrusion 6 or the recessed portion 7, thereby extending the service life of the protrusion 6 or the recessed portion 7, and thus extending the service life of the motor.

[0115] The raised portion 6 is fixedly connected to the base 2 or the upper cover 1 or is integrally formed therewith.

[0116] In this embodiment, the raised portion 6 is fixedly connected to or integrally formed with the base 2 or the upper cover 1, thereby increasing the strength of the raised portion 6 and extending the service life of the raised portion 6, thereby extending the service life of the motor. In this embodiment, the raised portion 6 is integrally formed with the base 2 or the upper cover 1, thereby simplifying the connection between the raised portion 6 and the base 2 or the upper cover 1, reducing the space occupied by the raised portion 6 during installation, thereby reducing the size of the motor and increasing the range of applications of the motor.

[0117] In the first embodiment, if Figures 5-12 As shown, the raised portion 6 is provided on the base 2, and the recessed portion 7 is provided on the upper cover 1; in the second embodiment, as shown Figures 13-18 As shown, the raised portion 6 is provided on the upper cover 1, and the recessed portion 7 is provided on the base 2. Figure 18 As shown, when the protrusion 6 is provided on the upper cover 1, the connection between the protrusion 6 and the upper cover 1 adopts an arc transition to improve the strength of the connection between the protrusion 6 and the upper cover 1, and reduce the risk of damage to the connection between the protrusion 6 and the upper cover 1 during the use or transportation of the motor, thereby extending the service life of the protrusion 6 and further extending the service life of the motor.

[0118] Specifically, if Figure 12 and Figure 18 As shown, the protrusion 6 extends in a direction parallel to the bottom surface of the base 2 .

[0119] In this embodiment, the raised portion 6 extends in a direction parallel to the bottom surface of the base 2, so that when the upper cover 1 is installed on the base 2, the raised portion 6 can cooperate with the recessed portion 7 to fill the gap between the upper cover 1 and the base 2, reducing the risk of the connecting wire 21 bypassing the raised portion 6 and getting stuck in the gap between the upper cover 1 and the base 2 when the raised portion 6 is located above the base 2, thereby improving the working stability of the raised portion 6. Figure 12 As shown, when the protrusion 6 is provided on the base 2, the protrusion 6 protrudes from the side of the base 2 in a direction perpendicular to the thickness of the base 2;Figure 18 As shown, when the protrusion 6 is provided on the upper cover 1 , the protrusion 6 protrudes from the inner surface of the side wall of the upper cover 1 along the thickness direction of the side wall of the upper cover 1 .

[0120] Among them, such as Figure 11 As shown, the length h2 of the protrusion 6 extending in a direction parallel to the bottom surface of the base 2 satisfies: 0.5 mm ≤ h2 ≤ 2 mm.

[0121] In this embodiment, 0.5mm≤h2≤2mm can reduce the risk that the length of the protrusion 6 extending in a direction parallel to the bottom surface of the base 2 is too short, resulting in the protrusion 6 being unable to fill the installation gap between the base 2 and the upper cover 1. At the same time, it can reduce the risk that the length of the protrusion 6 extending in a direction parallel to the bottom surface of the base 2 is too long, resulting in the protrusion 6 protruding from the outer surface of the motor. Therefore, 0.5mm≤h2≤2mm can increase the working stability of the protrusion 6, thereby reducing the risk of the connecting wire 21 being stuck in the installation gap between the base 2 and the upper cover 1, and at the same time, can improve the flatness of the outer surface of the motor.

[0122] In addition, if Figure 15 and Figure 16 As shown, the contours of the raised portion 6 and the recessed portion 7 can be arc-shaped, which facilitates the processing of the raised portion 6 and the recessed portion 7 and reduces the production costs of the raised portion 6 and the recessed portion 7. At the same time, it can reduce the risk of safety problems caused by sharp corners in the contours of the raised portion 6 and the recessed portion 7, thereby improving the safety of use of the raised portion 6 and the recessed portion 7, and further improving the safety of use of the base 2 and the upper cover 1.
