Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a driving motor, a camera module and an electronic equipment. Background Art

[0002] Electronic devices such as mobile phones and tablets all have camera modules for taking pictures and videos. The camera module is usually integrated with a drive motor, which can drive the optical lens to achieve functions such as autofocus, optical image stabilization, and wide-angle tracking. At present, in the drive motor, the motion trajectory of the drive motor circuit board and the drive motor mover is prone to interference, affecting the assembly accuracy of the drive motor. Utility Model Content

[0003] The embodiments of the present application provide a driving motor, a camera module and an electronic device, which can solve the problem of interference between the motion trajectory of the circuit board and the mover of the driving motor and ensure the assembly accuracy of the driving motor.

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

[0005] case;

[0006] A carrier, the carrier is located in the shell, the carrier can move relative to the shell, and the carrier includes a top surface and a first side surface connected to each other;

[0007] A circuit board, the circuit board comprising a first board body, a second board body and a first connecting portion, the first board body is located between the top surface and the inner surface of the shell, the second board body is located between the first side surface and the inner surface of the shell, and the first connecting portion is bent and connected between the first board body and the second board body; and

[0008] A reinforcing piece, the reinforcing piece comprising a first extension portion, a second extension portion and a transition portion, the first extension portion being located between the inner surface of the shell and the first plate body and connected to the first plate body, the second extension portion being located between the inner surface of the shell and the second plate body and connected to the second plate body, at least one of the first extension portion and the second extension portion being connected to the shell, and the transition portion being bent and connected between the first extension portion and the second extension portion;

[0009] The transition portion is stacked with the first connection portion and is located on a side of the first connection portion away from the carrier, and a bending radius of the transition portion is greater than a bending radius of the first connection portion.

[0010] It is understandable that, since the reinforcing member is located on the side of the circuit board away from the carrier, the reinforcing member can play a good supporting and reinforcing role on the circuit board during the bending process of the circuit board. On the one hand, the transition part of the reinforcing member is stacked with the first connecting part of the circuit board, and the bending radius of the transition part of the reinforcing member is also greater than the bending radius of the first connecting part of the circuit board. It can be ensured that during the bending process of the transition part of the reinforcing member and the first connecting part of the circuit board, the transition part of the reinforcing member located on the outside will not be squeezed to the first connecting part of the circuit board located on the inside, so that the bending of the two will not affect each other, effectively avoiding the reinforcing member from squeezing the circuit board during the bending process, causing the circuit board to synchronously squeeze the carrier and interfere with the movement trajectory of the carrier, affecting the working performance of the drive motor. On the other hand, the transition part of the reinforcing member is stacked with the first connecting part of the circuit board, and the bending radius of the transition part of the reinforcing member is also greater than the bending radius of the first connecting part of the circuit board, so that the transition part of the reinforcing member and the first connecting part of the circuit board have a good fit, fully improve the interference layering between the circuit board and the reinforcing member, and can also ensure the assembly accuracy of the drive motor and the working performance of the drive motor.

[0011] Alternatively, the transition portion is closer to the carrier than the first connecting portion, and the transition portion is penetrated by at least a portion of the first connecting portion.

[0012] It is understandable that, since the transition portion of the reinforcing piece is close to the carrier relative to the first connection portion of the circuit board, and the transition portion of the reinforcing piece is passed through by at least part of the first connection portion of the circuit board, an avoidance through hole is provided in the transition portion of the reinforcing piece for the first connection portion of the circuit board to pass through. On the one hand, the transition portion of the reinforcing piece is passed through by at least part of the first connection portion of the circuit board, so that at least part of the first connection portion of the circuit board can be located on the side of the transition portion of the reinforcing piece away from the carrier, so that the bending of the transition portion of the reinforcing piece can effectively avoid the bending of the first connection portion of the circuit board, and avoid the transition portion of the reinforcing piece from squeezing the circuit board during the bending process, so that the circuit board synchronously squeezes the carrier, resulting in interference with the movement trajectory of the carrier, and the reliability is better. On the other hand, the transition portion of the reinforcing piece is passed through by at least part of the first connection portion of the circuit board, which can not only provide good support and reinforcement for the circuit board, but also improve the interference layering between the circuit board and the reinforcing piece, which is conducive to ensuring the assembly accuracy of the drive motor and the working performance of the drive motor.

[0013] In a possible implementation manner, the second extension portion can be bent relative to the first extension portion through the transition portion, and when the second extension portion is not bent relative to the first extension portion, the transition portion is in a natural state, and when the second extension portion is bent relative to the first extension portion, the transition portion is in an extended state;

[0014] The length of the transition portion in the extended state is greater than the length of the transition portion in the natural state.

[0015] It is understandable that, since the second extension portion of the reinforcing piece can be bent relative to the first extension portion of the reinforcing piece through the transition portion of the reinforcing piece, when the second extension portion of the reinforcing piece is bent relative to the first extension portion of the reinforcing piece, the transition portion of the reinforcing piece is in an extended state and is bent and connected between the second extension portion of the reinforcing piece and the first extension portion of the reinforcing piece. In addition, since the length of the transition portion of the reinforcing piece in the extended state is greater than the length of the transition portion of the reinforcing piece in the natural state, during the bending process of the reinforcing piece and the circuit board together, the transition portion of the reinforcing piece will be stretched and extended outwards along with the bending, so that the length of the transition portion of the reinforcing piece gradually adapts to the bending trend of the first connection portion of the circuit board, effectively improving the ductility of the reinforcing piece, and preventing the reinforcing piece from squeezing the circuit board during the bending process, so that the circuit board and the reinforcing piece can have a better fit, and effectively improving the interference and delamination problem between the circuit board and the reinforcing piece.

[0016] In a possible implementation manner, the transition portion includes a plurality of connecting segments, and the plurality of connecting segments are crossed to form a grid structure having a plurality of first hollow areas.

[0017] It is understandable that by making the transition part of the reinforcing piece include multiple connecting segments and making the multiple connecting segments cross-arranged, the multiple connecting segments can be surrounded to form multiple first hollow areas, so that the transition part of the reinforcing piece presents a mesh hollow structure as a whole. Under this arrangement, since the transition part has multiple hollow areas, the transition part as a whole can reduce the structural strength and improve the tensile ductility while meeting the bending requirements (such as the transition part will not break during the bending process).

[0018] In a possible implementation manner, the transition portion includes a first wall and a second wall, and the first wall and the second wall are arranged opposite to each other in a width direction of the transition portion;

[0019] The transition portion has a plurality of second hollow areas and a plurality of third hollow areas, and along the direction from the first extension portion to the second extension portion, the second hollow areas and the third hollow areas are alternately arranged;

[0020] The distance from one end of the second hollow area to the first wall is a first distance, the distance from the other end of the second hollow area to the second wall is a second distance, the distance from one end of the third hollow area to the first wall is a third distance, and the distance from the other end of the third hollow area to the second wall is a fourth distance, the first distance is different from the third distance, and the second distance is different from the fourth distance.

[0021] It can be understood that, since the first distance from the second hollow area to the first wall is different from the third distance from the second hollow area to the first wall, the first distance from the second hollow area to the first wall is different from the third distance from the second hollow area to the first wall. Therefore, the first hollow area and the second hollow area are not arranged end to end, but are arranged in a stepped manner with a gradient difference. In addition, since the second hollow areas and the third hollow areas are arranged alternately and spaced in a plurality of second hollow areas and a plurality of third hollow areas, the arrangement of the plurality of second hollow areas and the plurality of third hollow areas is an S-shaped hollow arrangement as a whole. Under this setting, since the transition portion has a plurality of hollow areas, and the hollow areas are arranged in an S-shaped hollow arrangement, the remaining entity structure in the transition portion of the reinforcement can present a spring-like shape, so that the transition portion of the reinforcement has better tensile ductility during the bending process. As a result, the transition portion as a whole can reduce the structural strength and improve the tensile ductility on the basis of meeting the bending requirements (such as the transition portion will not break during the bending process).

[0022] In a possible implementation, one end of the second hollow area passes through the first wall, and the other end of the second hollow area is spaced apart from the second wall; one end of the third hollow area is spaced apart from the first wall, and the other end of the third hollow area passes through the second wall.

[0023] Under this setting, the hollowing process of the transition part can be started from the side wall of the transition part, or the hollowing process of the transition part can be terminated at the side wall of the transition part, so that the side wall of the transition part can serve as the starting line or the ending line of the hollowing process.

[0024] In a possible implementation manner, the transition portion includes a straight segment, a first bent segment, and a second bent segment, the extension direction of the straight segment intersects with the extension direction of the first extension portion and the extension direction of the second extension portion, the first bent segment is bent and connected between the first extension portion and one end of the straight segment, and the second bent segment is bent and connected between the other end of the straight segment and the second extension portion;

[0025] The transition portion has a fourth hollow area, which is located at one or more of the straight line segment, the first bending segment and the second bending segment. At least part of the first connecting portion passes through the fourth hollow area, and the first connecting portion extending out of the fourth hollow area protrudes toward the inner surface of the shell.

[0026] It is understandable that, since the transition portion of the reinforcing member has two bending sections, the transition portion of the reinforcing member will actually be bent twice. By bending the transition portion of the reinforcing member twice, the reinforcing member and the circuit board can be kept the same bending length while avoiding the circuit board, thereby optimizing the stress concentration problem of the transition portion of the reinforcing member, and improving the problem of the circuit board interfering with the motion trajectory of the carrier due to the reinforcing member squeezing the circuit board, reducing the adverse effects on the circuit board and the carrier, and improving reliability.

[0027] In a possible implementation manner, a bending length of the transition portion is the same as a bending length of the first connecting portion.

[0028] It is understandable that, since the second extension of the reinforcing piece can be bent relative to the first extension of the reinforcing piece through the transition portion of the reinforcing piece, when the second extension of the reinforcing piece is bent relative to the first extension of the reinforcing piece, the transition portion of the reinforcing piece is bent and connected between the second extension of the reinforcing piece and the first extension of the reinforcing piece. The bending length of the transition portion of the reinforcing piece is the same as the bending length of the first connecting portion of the circuit board, which can reduce or eliminate the tension applied to the transition portion of the reinforcing piece by the first extension and the second extension at both ends of the transition portion of the reinforcing piece during the bending process, avoid the transition portion of the reinforcing piece from being broken due to stretching during the bending process, and optimize the stress concentration problem of the transition portion of the reinforcing piece. In addition, it can also avoid the reinforcing piece from squeezing the circuit board during the bending process, so that the circuit board and the reinforcing piece can have a better fit, and effectively improve the interference and delamination problem between the circuit board and the reinforcing piece.

[0029] In a possible embodiment, the circuit board also includes a second connecting portion and a third plate body, the second connecting portion is bent and connected between the second plate body and the third plate body, one end of the third plate body connected to the second connecting portion is located inside the shell, the third plate body passes through the shell, and the other end of the third plate body is located outside the shell and is used to connect to the main board.

[0030] Under this configuration, an electrical connection between the drive motor and the mainboard of the electronic device can be achieved through the circuit board to facilitate the transmission of electrical signals.

[0031] In a possible implementation, the carrier further includes a second side surface and a third side surface disposed opposite to each other, the first side surface and the top surface are both connected between the second side surface and the third side surface, the carrier has a lens mounting hole, the lens mounting hole passes through the second side surface and the third side surface, and the lens mounting hole is used to mount an optical lens.

[0032] In a second aspect, the present application also provides a camera module, which includes an optical lens and a driving motor as described above, wherein the optical lens is installed in the driving motor.

[0033] Exemplarily, the optical lens may be a fixed focus lens, or the optical lens may be a zoom lens. The optical lens may include a lens barrel and an optical lens group. The lens barrel may be used to fix and protect the optical lens group. The optical lens group is installed in the lens barrel. The optical lens group may include at least one optical lens. When the optical lens group includes a plurality of optical lenses, the plurality of optical lenses are stacked along the optical axis direction of the optical lens. It should be noted that by designing the structural composition of the optical lens group and the shape and size of each optical lens, an optical lens with different characteristics such as standard and telephoto can be obtained.

[0034] In a third aspect, the present application also provides an electronic device, comprising a mainboard and the camera module as described above, wherein the camera module is electrically connected to the mainboard. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0071] And / or: It is just a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0072] Multiple: refers to two or more than two.

[0073] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either direct or indirect through an intermediary.

[0074] The specific implementation of the present application will be clearly described below in conjunction with the accompanying drawings.

[0075] The embodiments of the present application provide a driving motor, a camera module and an electronic device. The electronic device may be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The wearable device may be a smart bracelet, a smart watch, a smart head-mounted display, smart glasses, etc.

[0076] The following description will take the electronic device as a mobile phone as an example, but it should be understood that it is not limited to this.

[0077] See also Figure 1 , Figure 1 3 is a schematic diagram of the structure of an electronic device 300 provided in an embodiment of the present application. The electronic device 300 may include a frame 310, a display screen 320, a back cover 330, a mainboard 340 and a camera module 200. In the following, for the sake of convenience, the length direction of the electronic device 300 is defined as the X direction, the width direction of the electronic device 300 is defined as the Y direction, and the height direction of the electronic device 300 is defined as the Z direction. The X direction, the Y direction and the Z direction are perpendicular to each other.

[0078] The display screen 320 and the back cover 330 are connected to opposite sides of the frame 310, respectively. The display screen 320, the frame 310 and the back cover 330 can be enclosed to form a receiving space, and the receiving space can accommodate the mainboard 340 and other components of the electronic device 300. For example, when the electronic device 300 is a mobile phone, the frame 310 can be the middle frame of the mobile phone, and the display screen 320 can be a cover plate for displaying visual information such as images, colors, and texts for users. The back cover 330 can be the back cover of a mobile phone, and the back cover 330 can be an integrally formed cover plate or a cover plate formed by splicing multiple parts.

[0079] The mainboard 340 may be located in the receiving space. The mainboard 340 is the hub and control center of the electronic device 300, and can coordinate and manage the work of various hardware components in the electronic device 300, as well as process and transmit data information. Exemplarily, the mainboard 340 may be a PCB (Printed Circuit Board).

[0080] The camera module 200 enables the electronic device 300 to realize one or more of the functions of real-time image acquisition, instant video call, or acquisition of three-dimensional information of the object to be measured. It can be used as a front camera to capture static images or dynamic videos in front of the electronic device 300, or as a rear camera to capture static images or dynamic videos behind the electronic device 300. The camera module 200 can be electrically connected to the mainboard 340 so that the mainboard 340 receives and processes the electrical signal containing image information from the camera module 200, and controls the camera module 200 to work to realize functions such as wide-angle tracking, ultra-wide-angle photography, optical image stabilization (OIS) or automatic focusing (AF). Exemplarily, the camera module 200 can be a rear camera of the electronic device 300. The camera module 200 can be installed on the back cover 330, which can be completely located in the receiving space. Alternatively, the camera module 200 may be installed on the back cover 330 , and may be partially located in the receiving space and partially protrude from the back cover 330 .

[0081] The camera module 200 may be an upright camera module or a periscope camera module. The specific structure of the camera module 200 will be described below by taking the camera module 200 as a periscope camera module as an example, but it should be understood that this is not limited to this.

[0082] See also Figure 2 , Figure 2 yes Figure 1 The structure of the camera module 200 of the electronic device 300 is shown. Figure 2, the dotted arrow path is the transmission path of the light L. The camera module 200 may include an optical path turning element 210, an optical lens 220, a drive motor 100 and a photosensitive element 230. The optical path turning element 210 can change the transmission path of the light. The optical lens 220 can image the object being photographed. The drive motor 100 can drive the optical lens 220 to move along the optical axis direction of the optical lens 220 (i.e., the X direction or the opposite direction of the X direction) to achieve automatic focus. The drive motor 100 can also drive the optical lens 220 to move along the optical axis direction perpendicular to the optical lens 220 (i.e., the Y direction or the opposite direction of the Y direction) to achieve anti-shake. The photosensitive element 230 is used to sense light signals and convert the light signals into electrical signals and output them to the mainboard 340. This achieves image capture.

[0083] in, Figure 2 The purpose of the figure is to schematically describe the connection relationship between the optical path turning element 210, the optical lens 220, the driving motor 100 and the photosensitive element 230, and the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the camera module 200. In other embodiments of the present application, the camera module 200 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently.

[0084] The optical path turning element 210, the optical lens 220 and the photosensitive element 230 can be arranged in a direction parallel to the XY plane, wherein the optical lens 220 is installed in the driving motor 100, and the direction parallel to the XY plane can be parallel to the X direction or parallel to the Y direction. Under this setting, by arranging the components in the camera module 200 in a direction parallel to the XY plane, the occupied height of the camera module 200 in the Z direction can be reduced, which is conducive to the thinning of the electronic device 300. Exemplarily, the optical path turning element 210, the optical lens 220 and the photosensitive element 230 can be arranged in the X direction or the Y direction. Figure 2 The arrangement of the optical path turning element 210, the optical lens 220 and the photosensitive element 230 in the Y direction is taken as an example for explanation, but it should be understood that the present invention is not limited to this.

[0085] The optical path turning element 210 may include a light incident surface 2101, a light emitting surface 2102, and a reflective surface 2103. The light incident surface 2101 of the optical path turning element 210 is a surface of the optical path turning element 210 for the light L to be incident on, and the light incident surface 2101 of the optical path turning element 210 may be parallel to the XY plane. The light emitting surface 2102 of the optical path turning element 210 is a surface of the optical path turning element 210 for the light L to be emitted from, and the light emitting surface 2102 of the optical path turning element 210 may be parallel to the XZ plane and perpendicular to the light incident surface 2101. The reflective surface 2103 of the optical path turning element 210 is a surface of the optical path turning element 210 that can change the transmission path of the light L by reflection, and the reflective surface 2103 of the optical path turning element 210 may be inclined at 45° relative to the light incident surface 2101 and the light emitting surface 2102. After the light L enters the electronic device 300, it enters the light path turning element 210 through the light incident surface 2101 of the light path turning element 210, and is reflected by the reflection surface 2103 of the light path turning element 210 and then emitted from the light exit surface 2102 of the light path turning element 210. Thus, the light path turning element 210 can change the transmission path of the light L to form an L-shaped transmission path, and the light path turning element 210, the optical lens 220, and the photosensitive element 230 are arranged along the Y direction, which can reduce the occupied height of the camera module 200 in the Z direction, and is conducive to realizing the thinness of the electronic device 300.

[0086] Exemplarily, the light path turning element 210 can turn the light L incident along the Z direction to be emitted along the Y direction. The light path turning element 210 can be a right-angle prism. The two right-angle surfaces of the right-angle prism are respectively the light incident surface 2101 of the light path turning element 210 and the light exiting surface 2102 of the light path turning element 210. The inclined surface of the right-angle prism is the reflecting surface 2103 of the light path turning element 210. Of course, in other embodiments, the light path turning element 210 can also be a flat prism or a mirror reflector set at an angle.

[0087] The optical lens 220 is installed in the driving motor 100 to fix and protect the optical lens 220 through the driving motor 100, so that the driving motor 100 and the optical lens 220 are integrated into one, which is beneficial to reducing the volume of the camera module 200. The optical axis direction of the optical lens 220 can be consistent with the arrangement direction (i.e., the Y direction) of the optical path turning element 210, the driving motor 100 on which the optical lens 220 is installed, and the photosensitive element 230. The optical lens 220 may include a light incident surface 2201 and a light emitting surface 2202. The light incident surface 2201 of the optical lens 220 is the surface of the optical lens 220 that faces the light emitting surface 2102 of the light path turning element 210 when the optical lens 220 is in use. After the light L is emitted from the light emitting surface 2202 of the light path turning element 210, it is emitted into the optical lens 220 from the light incident surface 2201 of the optical lens 220. The light emitting surface 2202 of the optical lens 220 is the surface of the optical lens 220 facing away from the light path turning element 210 when the optical lens 220 is in use. After the light L enters the optical lens 220 , it is emitted from the optical lens 220 through the light emitting surface 2202 of the optical lens 220 .

[0088] Exemplarily, the optical lens 220 may be a fixed focus lens, or the optical lens 220 may also be a zoom lens. The optical lens 220 may include a lens barrel and an optical lens group. The lens barrel may be used to fix and protect the optical lens group. The optical lens group is installed in the lens barrel. The optical lens group may include at least one optical lens. When the optical lens group includes a plurality of optical lenses, the plurality of optical lenses are stacked along the optical axis direction of the optical lens 220. It should be noted that by designing the structural composition of the optical lens group and the shape and size of each optical lens, an optical lens 220 with different characteristics such as standard and telephoto can be obtained.

[0089] The photosensitive element 230 is arranged opposite to the light emitting surface 2202 of the optical lens 220. The light L enters the optical lens 220 to form an image of the object to be photographed, and the imaged light signal enters the photosensitive element 230, which converts the light signal into an electrical signal and outputs it to the main board 340, thereby achieving image capture.

[0090] That is, the light L outside the camera module 200 can be incident on the optical path turning element 210 along the Z direction. The light L entering the optical path turning element 210 has its transmission path turned under the action of the optical path turning element 210, and turns from propagating along the Z direction to propagating along the arrangement direction of the optical path turning element 210, the optical lens 220 and the photosensitive element 230 (that is, the Y direction), and after entering the optical lens 220, passes through the optical lens 220 and finally enters the photosensitive element 230. By driving the optical lens 220 to move in the arrangement direction of the optical path turning element 210, the driving motor 100 on which the optical lens 220 is installed and the photosensitive element 230 (that is, the Y direction or the opposite direction of the Y direction), the automatic focus function of the camera module 200 can be realized. In addition, the anti-shake function of the camera module 200 can be realized by driving the optical lens 220 to move in a direction perpendicular to the optical path turning element 210, the driving motor 100 on which the optical lens 220 is installed, and the arrangement direction of the photosensitive element 230 (i.e., the X direction or the opposite direction of the X direction) through the driving motor 100.

[0091] It is understandable that, since the focus limit distance of the autofocus function and the thickness of the electronic device 300 in the Z direction do not affect each other, the focus limit distance of the camera module 200 can be designed to be larger. Therefore, the camera module 200 can be used as a telephoto camera module to realize the telephoto shooting function of the electronic device 300. Of course, in other embodiments, the camera module 200 can also be used as the main camera module of the electronic device 300, and there is no strict limitation on this.

The circuit board 30 can be electrically connected to the main board 340 of the electronic device 300, so that the main board 340 can realize the movement of the carrier 20 relative to the housing 10 by controlling the first drive assembly 50 and the second drive assembly 60. The reinforcement 40 can be attached to the circuit board 30 to support and protect the circuit board 30. The ball 70 can realize a sliding connection between the housing 10 and the carrier 20.

The third side plate 124 of the top cover 12 is disposed opposite to the sixth side plate 114 of the base 11 in the opposite direction of the Y direction.

[0100] Please refer to Figure 8a and Figure 8b , Figure 8a yes Figure 3 The schematic diagram of the structure of the carrier 20 of the driving motor 100 at an angle is shown. Figure 8b yes Figure 3 The schematic structural diagram of the carrier 20 of the driving motor 100 is shown at another angle.

[0101] The carrier 20 is located in the accommodating space W of the housing 10, and the carrier 20 can move relative to the housing 10 in the XY plane, wherein the movement in the XY plane may include moving in the X direction, moving in the opposite direction of the X direction, moving in the Y direction, and moving in the opposite direction of the Y direction. The carrier 20 may include a top surface 201, a bottom surface 202, and a first side surface 203, a second side surface 204, a third side surface 205, and a fourth side surface 206 connected between the top surface 201 and the bottom surface 202. The top surface 201 of the carrier 20 and the bottom surface 202 of the carrier 20 are arranged relative to each other in the Z direction, the first side surface 203 of the carrier 20 and the fourth side surface 206 of the carrier 20 are arranged relative to each other in the X direction, and the second side surface 204 of the carrier 20 and the third side surface 205 of the carrier 20 are both connected between the first side surface 203 of the carrier 20 and the fourth side surface 206 of the carrier 20, and are arranged relative to each other in the Y direction.

[0102] The carrier 20 may have a lens mounting hole 21, a first groove 22, a second groove 23 and a slide groove 24. The lens mounting hole 21 of the carrier 20 may be a through hole and penetrates the second side surface 204 and the third side surface 205 of the carrier 20 along the Y direction. The lens mounting hole 21 of the carrier 20 may be used to mount the optical lens 220 to improve the mounting stability of the optical lens 220, and may drive the optical lens 220 to move together with the movement of the carrier 20. Specifically, the carrier 20 may drive the optical lens 220 to move relative to the housing 10 along the X direction, the opposite direction of the X direction, the Y direction and the opposite direction of the Y direction to realize the anti-shake function of the camera module 200. The carrier 20 may also drive the optical lens 220 to move relative to the housing 10 along the X direction and the opposite direction of the X direction to change the distance between the optical lens 220 and the optical path turning element 210 to realize the focusing function of the camera module 200.

[0103] Exemplarily, the optical lens 220 can be installed in the lens mounting hole 21 by a detachable manner such as a snap connection or a threaded connection, so as to facilitate the replacement of the optical lens 220. Alternatively, the optical lens 220 can also be installed in the lens mounting hole 21 by a non-detachable manner such as gluing or welding. When the optical lens 220 is installed in the lens mounting hole 21 of the carrier 20, the extension direction of the optical axis of the optical lens 220 (i.e., the Y direction) is consistent with the axial direction of the lens mounting hole 21 (i.e., the Y direction).

[0104] See also Figure 8a , the opening of the first groove 22 may be located on the top surface 201 of the carrier 20, the first groove 22 extends from the top surface 201 of the carrier 20 to the bottom surface 202 of the carrier 20, and the first groove 22 may be used to accommodate the first driving assembly 50. The number of the first grooves 22 may be one or more. When the number of the first grooves 22 is multiple, the multiple first grooves 22 may be used to accommodate multiple first driving assemblies 50 in accordance with the corresponding relationship that one first groove 22 accommodates one first driving assembly 50. Exemplarily, the number of the first grooves 22 may be two. The two first grooves 22 are spaced apart in the X direction. One first groove 22 passes through the first side surface 203 of the carrier 20, and the other first groove 22 passes through the fourth side surface 206 of the carrier 20.

[0105] See also Figure 8b, the opening of the second groove 23 can be located at the bottom surface 202 of the carrier 20, the second groove 23 extends from the bottom surface 202 of the carrier 20 to the top surface 201 of the carrier 20, and the second groove 23 can be used to accommodate the second drive assembly 60. The number of the second grooves 23 can be one or more. When the number of the second grooves 23 is multiple, the multiple second grooves 23 can be used to accommodate multiple second drive assemblies 60 according to the corresponding relationship that one second groove 23 accommodates one second drive assembly 60. Exemplarily, the number of the second grooves 23 can be two. The two second grooves 23 are spaced apart in the X direction. One second groove 23 runs through the first side surface 203 of the carrier 20, and the other second groove 23 runs through the fourth side surface 206 of the carrier 20.

[0106] The opening of the slide groove 24 can be located at the bottom surface 202 of the carrier 20, and the slide groove 24 extends from the bottom surface 202 of the carrier 20 to the top surface 201 of the carrier 20. The slide groove 24 can be located at the edge of the carrier 20, and can be used for the ball 70 to slide therein, so that the carrier 20 and the housing 10 are slidably connected through the ball 70. The number of the slide grooves 24 can be multiple, and the multiple slide grooves 24 are arranged at intervals along the circumferential direction of the carrier 20 at the edge of the carrier 20, and each slide groove 24 can be used to accommodate a ball 70. Among them, the circumferential direction of the carrier 20 is the direction around the central axis of the carrier 20, and the central axis of the carrier 20 is parallel to the Z direction. Exemplarily, the number of the slide grooves 24 can be four, and the four slide grooves 24 are respectively arranged at the four corners of the carrier 20, and each slide groove 24 is used to accommodate a ball 70. Of course, in other embodiments, the cooperation mode of the ball 70 and the slide groove 24 can also be adopted instead of the cooperation mode of the slider and the slide groove, which is not strictly limited.

[0107] In a possible implementation, Figure 8aAs shown, the drive motor 100 may further include a plurality of anti-collision structures 25, which may be arranged on the outer surface of the carrier 20 and located in the edge region of the carrier 20. One end of each anti-collision structure 25 is connected to the carrier 20, and the other end of each anti-collision structure 25 extends in a direction away from the carrier 20. Exemplarily, the number of anti-collision structures 25 may be sixteen, and the sixteen anti-collision structures 25 are divided into four groups of four, and the four groups of anti-collision structures 25 are respectively arranged on the top surface 201 of the carrier 20, the first side surface 203 of the carrier 20, the second side surface 204 of the carrier 20, and the fourth side surface 206 of the carrier 20. The four anti-collision structures 25 arranged on the top surface 201 of the carrier 20 may be respectively arranged at the four corners of the top surface 201. The four anti-collision structures 25 arranged on the first side surface 203 of the carrier 20 may be respectively arranged at the four corners of the first side surface 203. The four anti-collision structures 25 arranged on the second side surface 204 of the carrier 20 may be respectively arranged at the four corners of the second side surface 204. The four anti-collision structures 25 disposed on the fourth side surface 206 of the carrier 20 may be disposed at four corners of the fourth side surface 206 , respectively.

[0108] It is understandable that by providing a plurality of anti-collision structures 25, the anti-collision structures 25 can be used as buffers to mitigate the strong impact force generated by the direct impact of the housing 10 when the carrier 20 moves relative to the housing 10, and help avoid the problem of damage to the carrier 20 due to the impact. In addition, by providing a plurality of anti-collision structures 25 at the edge area of ​​the carrier 20, the moving distance of the carrier 20 along one or more of the X direction, the Y direction, the opposite direction of the X direction, and the opposite direction of the Y direction can be limited by the extended length of the anti-collision structures 25.

[0109] Please refer to Fig. 9 and Fig.10 , Fig. 9 yes Figure 3 The schematic diagram of the assembly structure of the carrier 20 of the driving motor 100 and the first driving component 50 is shown in FIG. Fig.10 yes Figure 3 The schematic diagram of the structure of the first driving component 50 of the driving motor 100 is shown.

[0110] The first drive assembly 50 may be electrically connected to the circuit board 30. The number of the first drive assembly 50 may be one or more. When the number of the first drive assembly 50 is multiple, the multiple first drive assemblies 50 may be respectively arranged on both sides of the carrier 20. It is understandable that by providing multiple first drive assemblies 50 and making the multiple first drive assemblies 50 respectively arranged on both sides of the carrier 20, it is beneficial to balance the force of the first drive assembly 50 and ensure the driving stability of the first drive assembly 50. Exemplarily, the number of the first drive assembly 50 may be two, and the two first drive assemblies 50 are respectively arranged on both sides of the carrier 20, and the two first drive assemblies 50 are arranged opposite to each other in the X direction. The structure of the first drive assembly 50 will be described below by taking the structure of only one first drive assembly 50 as an example. In the absence of conflict, the introduction of the structure of one first drive assembly 50 can be applied to other first drive assemblies 50.

[0111] At least part of the first driving component 50 may be located in the first groove 22 of the carrier 20. The first driving component 50 may include a first magnet 51 and a first coil 52. One of the first magnet 51 and the first coil 52 may be connected to the carrier 20 as a mover, and the other of the first magnet 51 and the first coil 52 may be connected to the housing 10 (such as the top cover 12 of the housing 10) as a stator. When the carrier 20 moves relative to the housing 10, one of the first magnet 51 and the first coil 52 may be driven to move relative to the other. The following description will be given by taking the example that the first magnet 51 is connected to the carrier 20 and the first coil 52 is connected to the housing 10, but it should be understood that it is not limited to this.

[0112] The first magnet 51 may include a first magnet 511 and a second magnet 512. The first magnet 511 and the second magnet 512 are both disposed in the first groove 22 of the carrier 20, the first magnet 511 extends along the Y direction, the second magnet 512 also extends along the Y direction, and the first magnet 511 and the second magnet 512 are disposed side by side in the X direction. It is understandable that by providing the first groove 22 on the top surface 201 of the carrier 20 and arranging the first magnet 511 and the second magnet 512 in the first groove 22, the space occupied by the first magnet 511, the second magnet 512 and the carrier 20 after being assembled can be minimized, which is conducive to miniaturization and thinness of the camera module 200.

[0113] The first coil 52 may be located in the first groove 22 of the carrier 20, and the first coil 52 may be connected to the circuit board 30. The first coil 52 may include a first side 521 and a second side 522. The first side 521 of the first coil 52 extends along the Y direction, and the first side 521 of the first coil 52 is arranged opposite to the first magnet 511 in the Z direction. That is, the orthographic projection of the first side 521 of the first coil 52 on the first magnet 511 at least partially falls within the range of the first magnet 511. The second side 522 of the first coil 52 is arranged opposite to the first side 521 of the first coil 52 in the opposite direction of the X direction. The second side 522 of the first coil 52 extends along the Y direction, and the second side 522 of the first coil 52 is arranged opposite to the second magnet 512 in the Z direction. That is, the orthographic projection of the second side 522 of the first coil 52 on the second magnet 512 at least partially falls within the range of the second magnet 512.

[0114] When the first coil 52 is energized, under the action of the magnetic field of the first magnet 51, a force (Ampere force) in the X direction or in the opposite direction of the X direction can be generated between the first coil 52 and the first magnet 51, thereby driving the carrier 20 and the optical lens 220 arranged on the carrier 20 to move relative to the housing 10 in the X direction or in the opposite direction of the X direction, so as to realize the anti-shake function in the X direction or in the opposite direction of the X direction.

[0115] In a possible implementation, the first drive assembly 50 may further include a position detection member 53, which may be disposed on the circuit board 30 and located in the first coil 52, and the position detection member 53 may be electrically connected to the circuit board 30 and the first coil 52. The position detection member 53 may be used to detect the displacement of the carrier 20 relative to the housing 10, thereby accurately controlling the moving distance of the carrier 20 and the optical lens 220 disposed on the carrier 20. In order to improve the control accuracy of optical image stabilization. Exemplarily, the position detection member 53 may be a Hall sensor, a displacement sensor, and the like.

[0116] Please refer to Fig.11 and Fig.12 , Fig.11 yes Figure 3 The schematic diagram of the assembly structure of the carrier 20 of the driving motor 100 and the second driving component 60 is shown in FIG. Fig.12 yes Figure 3 The schematic diagram of the structure of the second driving component 60 of the driving motor 100 is shown.

[0117] The second drive assembly 60 may be electrically connected to the circuit board 30. The number of the second drive assembly 60 may be one or more. When the number of the second drive assembly 60 is multiple, the multiple second drive assemblies 60 may be respectively arranged on both sides of the carrier 20. It is understandable that by providing multiple second drive assemblies 60 and making the multiple second drive assemblies 60 respectively arranged on both sides of the carrier 20, it is beneficial to balance the force of the second drive assembly 60 and ensure the driving stability of the second drive assembly 60. Exemplarily, the number of the second drive assembly 60 may be two, and the two second drive assemblies 60 are respectively arranged on both sides of the carrier 20, and the two second drive assemblies 60 are arranged opposite to each other in the X direction. The structure of the second drive assembly 60 will be described below by taking the structure of only one second drive assembly 60 as an example. In the absence of conflict, the introduction of the structure of one second drive assembly 60 can be applied to other second drive assemblies 60.

[0118] At least part of the second driving component 60 may be located in the second groove 23 of the carrier 20. The second driving component 60 may include a second magnet 61 and a second coil 62. One of the second magnet 61 and the second coil 62 may be connected to the carrier 20 as a mover, and the other of the second magnet 61 and the second coil 62 may be connected to the housing 10 (such as the base 11 of the housing 10) as a stator. When the carrier 20 moves relative to the housing 10, one of the second magnet 61 and the second coil 62 may be driven to move relative to the other. The following description will be made by taking the example that the second magnet 61 is connected to the carrier 20 and the second coil 62 is connected to the housing 10, but it should be understood that it is not limited to this.

[0119] The second magnet 61 may include a third magnet 611 and a fourth magnet 612. The third magnet 611 and the fourth magnet 612 are both disposed in the second groove 23 of the carrier 20, the third magnet 611 extends along the X direction, the fourth magnet 612 also extends along the X direction, and the third magnet 611 and the fourth magnet 612 are disposed side by side in the Y direction. It is understandable that by providing the second groove 23 on the top surface 201 of the carrier 20 and arranging the third magnet 611 and the fourth magnet 612 in the second groove 23, the space occupied by the third magnet 611, the fourth magnet 612 and the carrier 20 after being assembled can be minimized, which is conducive to miniaturization and thinness of the camera module 200.

[0120] The second coil 62 may be located in the second groove 23 of the carrier 20, and the second coil 62 may be connected to the housing 10. The second coil 62 may include a third side 621 and a fourth side 622. The third side 621 of the second coil 62 extends along the X direction, and the third side 621 of the second coil 62 is arranged opposite to the third magnet 611 in the opposite direction of the Z direction. That is, the positive projection of the third side 621 of the second coil 62 on the third magnet 611 at least partially falls within the range of the third magnet 611. The fourth side 622 of the second coil 62 is arranged opposite to the third side 621 of the second coil 62 in the opposite direction of the Y direction. The fourth side 622 of the second coil 62 extends along the X direction, and the fourth side 622 of the second coil 62 is arranged opposite to the fourth magnet 612 in the opposite direction of the Z direction. That is, the positive projection of the fourth side 622 of the second coil 62 on the fourth magnet 612 at least partially falls within the range of the fourth magnet 612.

[0121] When the second coil 62 is energized, under the action of the magnetic field of the second magnet 61, a force (Ampere force) can be generated between the second coil 62 and the second magnet 61 along the optical axis direction of the optical lens 220 (Y direction or the opposite direction of the Y direction), thereby driving the carrier 20 and the optical lens 220 arranged on the carrier 20 to move relative to the shell 10 along the Y direction or the opposite direction of the Y direction, so as to realize the autofocus function of the camera module 200.

[0122] In a possible implementation, the second driving component 60 may further include a driving chip 63, which may be disposed on the housing 10 and located in the second coil 62, and the driving chip 63 may be electrically connected to the circuit board 30 and the second coil 62. The driving chip 63 may be used to detect the displacement of the carrier 20 relative to the housing 10, thereby accurately controlling the moving distance of the carrier 20 and the optical lens 220 disposed on the carrier 20, so as to improve the adjustment accuracy of the autofocus.

[0123] Please refer to Figure 3 and Fig.13 , Fig.13 is along Figure 3 The schematic cross-sectional view is shown along the cutting line AA.

[0124] The ball bearing 70 is located in the slide groove 24 of the carrier 20 and connected between the carrier 20 and the base 11 of the housing 10. The ball bearing 70 can realize rolling cooperation between the carrier 20 and the base 11 of the housing 10, so that the carrier 20 can move along the X direction / Y direction relative to the base 11 of the housing 10. The number of the ball bearings 70 can be multiple, and the multiple ball bearings 70 are accommodated in multiple slide grooves 24 of the carrier 20 according to a one-to-one correspondence relationship of one ball bearing 70 accommodated in one slide groove 24 of the carrier 20.

[0125] It is understandable that in order to ensure that the optical lens 220 can move along the optical axis direction (i.e., the Y direction) to achieve autofocus or move along the direction parallel to the XY plane to achieve anti-shake, a track for the carrier 20 to move can be set between the base 11 of the housing 10 and the carrier 20, and the track can be a matching mode of the ball 70 and the slide groove 24. By using the matching mode of the ball 70 and the slide groove 24 to achieve the connection between the carrier 20 and the base 11, the friction between the carrier 20 and the base 11 can be effectively reduced when the carrier 20 moves, thereby reducing the energy consumption of the camera module 200 when it is working, and the reliability is better.

[0126] Please refer to Fig.13 , Fig.14 and Fig.15 , Fig.14 yes Figure 3 The schematic diagram of the assembly structure of the carrier 20 and the circuit board 30 of the driving motor 100 is shown in FIG. Fig.15 yes Figure 3 The schematic diagram of the structure of the circuit board 30 of the driving motor 100 is shown.

[0127] Part of the circuit board 30 is disposed in the accommodation space W of the housing 10 and between the housing 10 and the carrier 20, and part of the circuit board 30 extends out of the housing 10 to be electrically connected to the mainboard 340 of the electronic device 300. Exemplarily, the circuit board 30 may be a flexible printed circuit (FPC) or a hard-soft combined circuit board.

[0128] The circuit board 30 may include a first board 31, a second board 32, a third board 33, a first connection portion 34, and a second connection portion 35. The first connection portion 34 is connected between the first board 31 and the second board 32, and the second connection portion 35 is connected between the second board 32 and the third board 33. That is, the first board 31, the first connection portion 34, the second board 32, the second connection portion 35, and the third board 33 are connected in sequence. The second board 32 can be bent relative to the first board 31 through the first connection portion 34, and the third board 33 can be bent relative to the second board 32 through the second connection portion 35. That is, the circuit board 30 has flexibility, and it can have the first board 31, the second board 32, and the third board 33 as non-bending parts, and it can also have the first connection portion 34 and the second connection portion 35 as bending parts.

[0129] It can be understood that by making the circuit board 30 include a bending portion that can be bent and a non-bending portion that cannot be bent, the circuit board 30 can be partially bent according to the spatial layout within the drive motor 100, so as to better adapt to the narrow and compact layout space within the drive motor 100, which is beneficial to improving the space utilization within the drive motor 100.

[0130] Specifically, when the circuit board 30 is assembled into the housing 10 of the driving motor 100, the first plate body 31 can be located between the top surface 201 of the carrier 20 and the inner surface of the housing 10, and the first plate body 31 covers part of the top surface 201 of the carrier 20. The first plate body 31 can also be connected to the first coil 52 and the position detection member 53 of the first driving component 50, so as to realize the connection between the first driving component 50 and the circuit board 30. The first connecting portion 34 can be bent and connected between the first plate body 31 and the second plate body 32, and is arranged opposite to the connection between the top surface 201 of the carrier 20 and the first side surface 203 of the carrier 20. The second plate body 32 can be located between the first side surface 203 of the carrier 20 and the inner surface of the housing 10, and the second plate body 32 covers part of the first side surface 203 of the carrier 20. The second connecting portion 35 can be bent and connected between the second plate body 32 and the third plate body 33, and is arranged opposite to the connection between the first side surface 203 of the carrier 20 and the bottom surface 202 of the carrier 20. One end of the third plate 33 is located in the accommodation space W of the housing 10, and the third plate 33 can pass through the second through hole 116 of the base 11 and the first through hole 126 of the top cover 12. The other end of the third plate 33 is located outside the housing 10 and is used to connect with the main board 340. Under this configuration, the electrical connection between the driving motor 100 and the main board 340 of the electronic device 300 can be achieved through the circuit board 30, so as to facilitate the transmission of electrical signals.

[0131] Based on the above description, it should be understood that during the assembly process of the drive motor 100, since the circuit board 30 has a certain flexibility, it needs to be partially bent during the assembly process to adapt to the spatial layout inside the drive motor 100. However, if the circuit board 30 is not supported and protected to a certain extent, it is easy to cause the circuit board 30 to fail, and then the working reliability of the camera module 200 is reduced. Therefore, in the embodiment of the present application, a layer of reinforcement 40 is provided on the circuit board 30 to strengthen the support and protection of the circuit board 30 during the bending process of the circuit board 30 and after the bending of the circuit board 30. Exemplarily, the material of the reinforcement 40 includes but is not limited to metals or plastics such as iron, iron alloy, aluminum, aluminum alloy, titanium alloy, magnesium-aluminum alloy, etc.

[0132] The structure of the reinforcing member 40 will be described in detail below through four specific embodiments.

[0133] First embodiment:

[0134] Please refer to Fig.16 and Fig.17 , Fig.16 yes Figure 3 The reinforcing member 40 of the first embodiment of the driving motor 100 is shown in a schematic diagram of an assembly at an angle after the circuit board 30 is bent. Fig.17 yes Fig.16The structure of the reinforcing member 40 is shown at an angle.

[0135] The reinforcing member 40 may include a first extension portion 41, a second extension portion 42 and a transition portion 43. The transition portion 43 is connected between the first extension portion 41 and the second extension portion 42, and the second extension portion 42 can be bent relative to the first extension portion 41 through the transition portion 43 (i.e., the first extension portion 41 can be bent relative to the second extension portion 42 through the transition portion 43). In other words, the reinforcing member 40 may have a natural state and an extended state. When the second extension portion 42 is not bent relative to the first extension portion 41, the transition portion 43 may be in a natural state. When the second extension portion 42 is bent relative to the first extension portion 41, the transition portion 43 may be in an extended state. It should be understood that the natural state of the reinforcing member 40 and the extended state of the reinforcing member 40 may be adapted to whether the circuit board 30 is bent. When the circuit board 30 does not need to be bent, the reinforcing member 40 may be in a natural state. When the circuit board 30 needs to be bent, the reinforcing member 40 is in an extended state because it needs to be bent together with the circuit board 30.

[0136] The first extension portion 41 of the reinforcing piece 40 can cover the first plate body 31 of the circuit board 30 and be connected to the first plate body 31 of the circuit board 30. The second extension portion 42 of the reinforcing piece 40 can cover the second plate body 32 of the circuit board 30 and be connected to the second plate body 32 of the circuit board 30. At least one of the first extension portion 41 and the second extension portion 42 of the reinforcing piece 40 is connected to the housing 10 of the driving motor 100, so that the reinforcing piece 40 is relatively fixed to the housing 10 of the driving motor 100. The transition portion 43 of the reinforcing piece 40 can be stacked with the first connection portion 34 of the circuit board 30. Thus, the various parts of the reinforcing piece 40 can be arranged corresponding to the various parts of the circuit board 30, so that the reinforcing piece 40 can be targeted according to the structure of each part of the circuit board 30, which is conducive to further ensuring the bending strength of the circuit board 30.

[0137] In this embodiment, the transition portion 43 may include a first portion 431 and a second portion 432, the first portion 431 and the second portion 432 are spaced apart in the Y direction, the first portion 431 is connected between the first extension portion 41 and the second extension portion 42, the second portion 432 is connected between the first extension portion 41 and the second extension portion 42, the first extension portion 41, the first portion 431, the second portion 432 and the second extension portion 42 are enclosed to form an exposure hole H of the transition portion 43, and the exposure hole H penetrates the transition portion 43 along the thickness direction of the transition portion 43. When the reinforcing member 40 is stacked with the circuit board 30, along the Y direction, the first portion 431 of the reinforcing member 40, the first connection portion 34 of the circuit board 30 and the second portion 432 of the reinforcing member 40 are spaced apart in sequence, and the first connection portion 34 of the circuit board 30 can be exposed through the exposure hole H of the transition portion 43.

[0138] When the reinforcing piece 40 and the circuit board 30 are bent, the first extension portion 41 of the reinforcing piece 40 can be located between the inner surface of the housing 10 and the first plate body 31 of the circuit board 30, and can be stacked with the first plate body 31 of the circuit board 30. The second extension portion 42 of the reinforcing piece 40 can be located between the inner surface of the housing 10 and the second plate body 32 of the circuit board 30, and can be stacked with the second plate body 32 of the circuit board 30. The transition portion 43 of the reinforcing piece 40 can be bent and connected between the first extension portion 41 of the reinforcing piece 40 and the second extension portion 42 of the reinforcing piece 40. Specifically, the first portion 431 of the reinforcement 40 is bent and connected between the first extension portion 41 of the reinforcement 40 and the second extension portion 42 of the reinforcement 40, and the second portion 432 of the reinforcement 40 is bent and connected between the first extension portion 41 of the reinforcement 40 and the second extension portion 42 of the reinforcement 40. Along the Y direction, the first portion 431 of the reinforcement 40, the first connection portion 34 of the circuit board 30 and the second portion 432 of the reinforcement 40 are arranged in sequence at intervals, and the first connection portion 34 of the circuit board 30 can be exposed through the exposure hole H of the transition portion 43.

[0139] Please refer to Fig.18 and Fig.19 , Fig.18 yes Fig.17 The reinforcing member 40 of the first embodiment is shown as a schematic diagram of assembly at another angle with the circuit board 30 before being bent. Fig.19 yes Fig.17 The reinforcing member 40 of the first embodiment is shown as a schematic diagram of the assembly of the circuit board 30 after the bending is completed.

[0140] In this embodiment, Fig.18 As shown, during the assembly process of the drive motor 100, the circuit board 30 is usually attached to the reinforcing member 40 for assembly due to its relatively soft material, so that the reinforcing member 40 can strengthen the support and protection of the circuit board 30. However, during the bending process of the circuit board 30, such as Fig.19 As shown, due to the poor ductility of the reinforcing piece 40, the bending radius of the transition portion 43 of the reinforcing piece 40 is likely to be smaller than the bending radius of the first connecting portion 34 of the circuit board 30, causing the transition portion 43 of the reinforcing piece 40 to squeeze the first connecting portion 34 of the circuit board 30 during the bending process, thereby causing the first connecting portion 34 of the circuit board 30 to separate from the transition portion 43 of the reinforcing piece 40 and bend in a direction away from the reinforcing piece 40, resulting in interference and delamination between the circuit board 30 and the reinforcing piece 40. The bending of the circuit board 30 in a direction away from the reinforcing piece 40 not only affects the assembly accuracy of the circuit board 30 and the reinforcing piece 40, but also causes the bending part of the circuit board 30 to protrude in the direction of the carrier 20 of the driving motor 100, causing the circuit board 30 to interfere with the motion trajectory of the carrier 20 as the mover of the driving motor 100, thereby affecting the working performance of the driving motor 100.

[0141] In order to solve the technical problems existing in the driving motor 100 in this embodiment, the second embodiment, the third embodiment and the fourth embodiment of the present application all provide a driving motor 100 that can solve the problem of interference and delamination between the reinforcement part 40 and the circuit board 30 after bending, which will be specifically described below.

[0142] Second embodiment:

[0143] Please refer to Fig.20a , Fig.20b , Fig.21 , Fig.22a and Figure 22b , Fig.20a yes Figure 3 The structure schematic diagram of the reinforcing member 40 of the second embodiment of the driving motor 100 is shown at an angle. Fig.20b yes Figure 3 The structure schematic diagram of the reinforcing member 40 of the second embodiment of the driving motor 100 shown in FIG. Fig.21 yes Fig.20a The reinforcing member 40 of the second embodiment is shown as a schematic diagram of the assembly of the circuit board 30 before being bent. Fig.22a yes Fig.20a The reinforcing member 40 of the second embodiment is shown as a schematic diagram of the assembly of the circuit board 30 at an angle after the circuit board 30 is bent. Figure 22b yes Fig.20a The reinforcing member 40 of the second embodiment is shown as a schematic diagram of the assembly of the circuit board 30 at another angle after the circuit board 30 is bent. Fig.22a In FIG. 4 , the direction of the dotted arrow is the stretching direction of the transition portion 43 .

[0144] In this embodiment, the same contents as those in the first embodiment are not repeated here. The difference from the first embodiment is that the transition portion 43 of the reinforcing member 40 is stacked with the first connection portion 34 of the circuit board 30 and is located on the side of the first connection portion 34 of the circuit board 30 away from the carrier 20. The bending radius of the transition portion 43 of the reinforcing member 40 is greater than the bending radius of the first connection portion 34 of the circuit board 30.

[0145] It is understandable that, since the reinforcing piece 40 is located on the side of the circuit board 30 away from the carrier 20, the reinforcing piece 40 can play a good supporting and reinforcing role on the circuit board 30 during the bending process of the circuit board 30. On the one hand, the transition portion 43 of the reinforcing piece 40 is stacked with the first connecting portion 34 of the circuit board 30, and the bending radius of the transition portion 43 of the reinforcing piece 40 is also greater than the bending radius of the first connecting portion 34 of the circuit board 30. It can be ensured that during the bending process of the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30, the transition portion 43 of the reinforcing piece 40 located on the outside will not be squeezed to the first connecting portion 34 of the circuit board 30 located on the inside, so that the bending of the two will not affect each other, effectively avoiding the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, causing the circuit board 30 to synchronously squeeze the carrier 20 and interfere with the motion trajectory of the carrier 20, affecting the working performance of the driving motor 100. On the other hand, the transition portion 43 of the reinforcement 40 is stacked with the first connecting portion 34 of the circuit board 30, and the bending radius of the transition portion 43 of the reinforcement 40 is also greater than the bending radius of the first connecting portion 34 of the circuit board 30, which can make the transition portion 43 of the reinforcement 40 and the first connecting portion 34 of the circuit board 30 have a better fit, fully improve the interference stratification between the circuit board 30 and the reinforcement 40, and also ensure the assembly accuracy of the drive motor 100 and the working performance of the drive motor 100.

[0146] The bending and protruding direction of the transition portion 43 of the reinforcing member 40 is the direction away from the carrier 20, and the bending and protruding direction of the first connection portion 34 of the circuit board 30 is also the direction away from the carrier 20. In other words, the bending center line of the transition portion 43 of the reinforcing member 40 and the bending center line of the first connection portion 34 of the circuit board 30 are located on the same side of the first connection portion 34 of the circuit board 30.

[0147] It is understandable that, since the bending and protruding direction of the transition portion 43 of the reinforcing piece 40 is facing away from the carrier 20, and the bending and protruding direction of the first connecting portion 34 of the circuit board 30 is also facing away from the carrier 20, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 have the same bending direction during the bending process and both bend in the direction facing away from the carrier 20. On the one hand, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 can both bend and protrude away from the carrier 20, so that the bending process of the reinforcing piece 40 and the circuit board 30 and the movement trajectory of the carrier 20 do not affect each other, and can effectively avoid the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, causing the circuit board 30 to synchronously squeeze the carrier 20 and interfere with the movement trajectory of the carrier 20, and the reliability is better. On the other hand, the transition portion 43 of the reinforcement piece 40 and the first connection portion 34 of the circuit board 30 can be bent and protruded away from the carrier 20, so that the transition portion 43 of the reinforcement piece 40 and the first connection portion 34 of the circuit board 30 can have a better fit, which can not only provide good support and reinforcement for the circuit board 30, but also improve the interference stratification between the circuit board 30 and the reinforcement piece 40, which is beneficial to ensure the assembly accuracy of the drive motor 100 and the working performance of the drive motor 100.

[0148] In a possible implementation, the bending centerline of the transition portion 43 of the reinforcing piece 40 coincides with the bending centerline of the first connecting portion 34 of the circuit board 30. Under this configuration, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 can have the same bending angle, thereby improving the interfering delamination problem between the reinforcing piece 40 and the circuit board 30, further improving the fit between the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30, and enhancing the connection performance between the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30.

[0149] In another possible embodiment, the bending center line of the transition portion 43 of the reinforcing piece 40 and the bending center line of the first connection portion 34 of the circuit board 30 are located on the same side of the first connection portion 34 of the circuit board 30, and there is a preset distance between the bending center line of the transition portion 43 of the reinforcing piece 40 and the bending center line of the first connection portion 34 of the circuit board 30. Under this setting, the transition portion 43 of the reinforcing piece 40 and the first connection portion 34 of the circuit board 30 can be bent in the same direction.

[0150] Please refer to Figure 20a-Figure 22bIn this embodiment, the second extension portion 42 of the reinforcing piece 40 can be bent relative to the first extension portion 41 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40 (i.e., the first extension portion 41 of the reinforcing piece 40 can be bent relative to the second extension portion 42 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40). The bending angle of the transition portion 43 of the reinforcing piece 40 is not limited and can be selected according to actual application conditions.

[0151] When the second extension portion 42 of the reinforcing piece 40 is not bent relative to the first extension portion 41 of the reinforcing piece 40, the transition portion 43 of the reinforcing piece 40 is in a natural state. During the bending process of the transition portion 43 of the reinforcing piece 40, the end of the transition portion 43 connected to the first extension portion 41 is stretched toward the direction of the first extension portion 41, and the end of the transition portion 43 connected to the second extension portion 42 is stretched toward the direction of the second extension portion 42, so that during the bending process of the reinforcing piece 40, the transition portion 43 as a whole can be stretched and extended outward. When the second extension portion 42 of the reinforcing piece 40 is bent relative to the first extension portion 41 of the reinforcing piece 40, the transition portion 43 of the reinforcing piece 40 is in an extended state. The length of the transition portion 43 of the reinforcing piece 40 in the extended state is greater than the length of the transition portion 43 of the reinforcing piece 40 in the natural state. The length of the transition portion 43 refers to the extension length between the two ends of the transition portion 43 (the end connected to the first extension portion 41 and the end connected to the second extension portion 42).

[0152] It can be understood that, since the second extension portion 42 of the reinforcement piece 40 can be bent relative to the first extension portion 41 of the reinforcement piece 40 through the transition portion 43 of the reinforcement piece 40, when the second extension portion 42 of the reinforcement piece 40 is bent relative to the first extension portion 41 of the reinforcement piece 40, the transition portion 43 of the reinforcement piece 40 is in an extended state and is bent and connected between the second extension portion 42 of the reinforcement piece 40 and the first extension portion 41 of the reinforcement piece 40. Furthermore, because the length of the transition portion 43 of the reinforcing piece 40 in the extended state is greater than the length of the transition portion 43 of the reinforcing piece 40 in the natural state, during the process of bending the reinforcing piece 40 together with the circuit board 30, the transition portion 43 of the reinforcing piece 40 will be stretched and extended outward along with the bending, so that the length of the transition portion 43 of the reinforcing piece 40 gradually adapts to the bending trend of the first connecting portion 34 of the circuit board 30, effectively improving the ductility of the reinforcing piece 40, and preventing the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, so that the circuit board 30 and the reinforcing piece 40 can have a better fit, and effectively improving the interference and delamination problem between the circuit board 30 and the reinforcing piece 40.

[0153] Please refer to Fig.20a and Fig.20bIn this embodiment, the transition portion 43 of the reinforcement piece 40 may include a plurality of connecting segments 433. The plurality of connecting segments 433 cross to form a grid structure having a plurality of first hollow areas Q1, and two adjacent first hollow areas Q1 are arranged at intervals. Exemplarily, the transition portion 43 of the reinforcement piece 40 may be hollowed out in a mesh shape by a stamping and etching process. The shape of the first hollow area Q1 may be a rhombus, a rectangle, a triangle, a polygon, etc. It should be noted that this embodiment does not impose strict restrictions on the size of the connecting segment 433, the number of the connecting segment 433, the shape of the connecting segment 433, the number of the first hollow areas Q1, the shape of the first hollow area Q1, the size of the first hollow area Q1, etc.

[0154] It is understandable that by making the transition portion 43 of the reinforcing piece 40 include a plurality of connecting segments 433 and making the plurality of connecting segments 433 cross-arranged, the plurality of connecting segments 433 can be surrounded to form a plurality of first hollow areas Q1, so that the transition portion 43 of the reinforcing piece 40 presents a mesh hollow structure as a whole. Under this arrangement, since the transition portion 43 has a plurality of hollow areas, the transition portion 43 as a whole can reduce the structural strength and improve the tensile ductility while meeting the bending requirements (such as the transition portion 43 will not break during the bending process).

[0155] Third embodiment:

[0156] Please refer to Fig.23a , Figure 23b , Fig.23c and Fig.24 , Fig.23a yes Figure 3 The reinforcing member 40 of the third embodiment of the driving motor 100 is a structural schematic diagram at an angle in a natural state, Figure 23b yes Figure 3 Another structural schematic diagram of the third embodiment of the driving motor 100 is a schematic diagram showing a reinforcing member 40 in a natural state at an angle. Fig.23c yes Fig.23a The reinforcing member 40 of the third embodiment of the driving motor 100 is a schematic structural diagram at an angle in an extended state, Fig.24 yes Fig.23a The reinforcing member 40 of the third embodiment is shown in a schematic diagram of the assembly of the circuit board 30 at an angle after the circuit board 30 is bent. Fig.23a In FIG. 4 , the direction of the dotted arrow is the stretching direction of the transition portion 43 .

[0157] In this embodiment, the same contents as those in the first embodiment are not repeated here. The difference from the first embodiment is that the transition portion 43 of the reinforcing member 40 is stacked with the first connection portion 34 of the circuit board 30 and is located on the side of the first connection portion 34 of the circuit board 30 away from the carrier 20. The bending radius of the transition portion 43 of the reinforcing member 40 is greater than the bending radius of the first connection portion 34 of the circuit board 30.

[0158] It is understandable that, since the reinforcing piece 40 is located on the side of the circuit board 30 away from the carrier 20, the reinforcing piece 40 can play a good supporting and reinforcing role on the circuit board 30 during the bending process of the circuit board 30. On the one hand, the transition portion 43 of the reinforcing piece 40 is stacked with the first connecting portion 34 of the circuit board 30, and the bending radius of the transition portion 43 of the reinforcing piece 40 is also greater than the bending radius of the first connecting portion 34 of the circuit board 30. It can be ensured that during the bending process of the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30, the transition portion 43 of the reinforcing piece 40 located on the outside will not be squeezed to the first connecting portion 34 of the circuit board 30 located on the inside, so that the bending of the two will not affect each other, effectively avoiding the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, causing the circuit board 30 to synchronously squeeze the carrier 20 and interfere with the motion trajectory of the carrier 20, affecting the working performance of the driving motor 100. On the other hand, the transition portion 43 of the reinforcement 40 is stacked with the first connecting portion 34 of the circuit board 30, and the bending radius of the transition portion 43 of the reinforcement 40 is also greater than the bending radius of the first connecting portion 34 of the circuit board 30, which can make the transition portion 43 of the reinforcement 40 and the first connecting portion 34 of the circuit board 30 have a better fit, fully improve the interference stratification between the circuit board 30 and the reinforcement 40, and also ensure the assembly accuracy of the drive motor 100 and the working performance of the drive motor 100.

[0159] The bending and protruding direction of the transition portion 43 of the reinforcing member 40 is the direction away from the carrier 20, and the bending and protruding direction of the first connection portion 34 of the circuit board 30 is also the direction away from the carrier 20. In other words, the bending center line of the transition portion 43 of the reinforcing member 40 and the bending center line of the first connection portion 34 of the circuit board 30 are located on the same side of the first connection portion 34 of the circuit board 30.

[0160] It is understandable that, since the bending and protruding direction of the transition portion 43 of the reinforcing piece 40 is facing away from the carrier 20, and the bending and protruding direction of the first connecting portion 34 of the circuit board 30 is also facing away from the carrier 20, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 have the same bending direction during the bending process and both bend in the direction facing away from the carrier 20. On the one hand, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 can both bend and protrude away from the carrier 20, so that the bending process of the reinforcing piece 40 and the circuit board 30 and the movement trajectory of the carrier 20 do not affect each other, and can effectively avoid the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, causing the circuit board 30 to synchronously squeeze the carrier 20 and interfere with the movement trajectory of the carrier 20, and the reliability is better. On the other hand, the transition portion 43 of the reinforcement piece 40 and the first connection portion 34 of the circuit board 30 can be bent and protruded away from the carrier 20, so that the transition portion 43 of the reinforcement piece 40 and the first connection portion 34 of the circuit board 30 can have a better fit, which can not only provide good support and reinforcement for the circuit board 30, but also improve the interference stratification between the circuit board 30 and the reinforcement piece 40, which is beneficial to ensure the assembly accuracy of the drive motor 100 and the working performance of the drive motor 100.

[0161] In a possible implementation, the bending centerline of the transition portion 43 of the reinforcing piece 40 coincides with the bending centerline of the first connecting portion 34 of the circuit board 30. Under this configuration, the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30 can have the same bending angle, thereby improving the interfering delamination problem between the reinforcing piece 40 and the circuit board 30, further improving the fit between the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30, and enhancing the connection performance between the transition portion 43 of the reinforcing piece 40 and the first connecting portion 34 of the circuit board 30.

[0162] In another possible embodiment, the bending center line of the transition portion 43 of the reinforcing piece 40 and the bending center line of the first connection portion 34 of the circuit board 30 are located on the same side of the first connection portion 34 of the circuit board 30, and there is a preset distance between the bending center line of the transition portion 43 of the reinforcing piece 40 and the bending center line of the first connection portion 34 of the circuit board 30. Under this setting, the transition portion 43 of the reinforcing piece 40 and the first connection portion 34 of the circuit board 30 can be bent in the same direction.

[0163] Please refer to Fig.23a , Figure 23b , Fig.23c and Fig.24In this embodiment, the second extension portion 42 of the reinforcing piece 40 can be bent relative to the first extension portion 41 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40 (i.e., the first extension portion 41 of the reinforcing piece 40 can be bent relative to the second extension portion 42 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40). The bending angle of the transition portion 43 of the reinforcing piece 40 is not limited and can be selected according to actual application conditions.

[0164] When the second extension portion 42 of the reinforcing piece 40 is not bent relative to the first extension portion 41 of the reinforcing piece 40, the transition portion 43 of the reinforcing piece 40 is in a natural state. During the bending process of the transition portion 43 of the reinforcing piece 40, the end of the transition portion 43 connected to the first extension portion 41 is stretched toward the direction of the first extension portion 41, and the end of the transition portion 43 connected to the second extension portion 42 is stretched toward the direction of the second extension portion 42, so that during the bending process of the reinforcing piece 40, the transition portion 43 as a whole can be stretched and extended outward. When the second extension portion 42 of the reinforcing piece 40 is bent relative to the first extension portion 41 of the reinforcing piece 40, the transition portion 43 of the reinforcing piece 40 is in an extended state. The length of the transition portion 43 of the reinforcing piece 40 in the extended state is greater than the length of the transition portion 43 of the reinforcing piece 40 in the natural state. The length of the transition portion 43 refers to the extension length between the two ends of the transition portion 43 (the end connected to the first extension portion 41 and the end connected to the second extension portion 42).

[0165] It can be understood that, since the second extension portion 42 of the reinforcement piece 40 can be bent relative to the first extension portion 41 of the reinforcement piece 40 through the transition portion 43 of the reinforcement piece 40, when the second extension portion 42 of the reinforcement piece 40 is bent relative to the first extension portion 41 of the reinforcement piece 40, the transition portion 43 of the reinforcement piece 40 is in an extended state and is bent and connected between the second extension portion 42 of the reinforcement piece 40 and the first extension portion 41 of the reinforcement piece 40. Furthermore, because the length of the transition portion 43 of the reinforcing piece 40 in the extended state is greater than the length of the transition portion 43 of the reinforcing piece 40 in the natural state, during the process of bending the reinforcing piece 40 together with the circuit board 30, the transition portion 43 of the reinforcing piece 40 will be stretched and extended outward along with the bending, so that the length of the transition portion 43 of the reinforcing piece 40 gradually adapts to the bending trend of the first connecting portion 34 of the circuit board 30, effectively improving the ductility of the reinforcing piece 40, and preventing the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, so that the circuit board 30 and the reinforcing piece 40 can have a better fit, and effectively improving the interference and delamination problem between the circuit board 30 and the reinforcing piece 40.

[0166] Please refer to Fig.23a , Figure 23b and Fig.23cIn this embodiment, the transition portion 43 of the reinforcing member 40 may include a first wall 434 and a second wall 435. The first wall 434 of the transition portion 43 and the second wall 435 of the transition portion 43 are arranged opposite to each other in the width direction (i.e., the Y direction) of the transition portion 43. The transition portion 43 of the reinforcing member 40 may have a plurality of second hollow areas Q2 and a plurality of third hollow areas Q3. Along the direction from the first extension portion 41 to the second extension portion 42, the second hollow areas Q2 and the third hollow areas Q3 are arranged alternately.

[0167] Along the Y direction, the distance from one end of the second hollow area Q2 to the first wall 434 is the first distance D1, and the distance from the other end of the second hollow area Q2 to the second wall 435 is the second distance D2. The distance from one end of the third hollow area Q3 to the first wall 434 is the third distance D3, and the distance from the other end of the third hollow area Q3 to the second wall 435 is the fourth distance D4. The first distance D1 is different from the third distance D3, and the second distance D2 is different from the fourth distance D4. Of course, in other embodiments, the first distance D1 may also be the same as the third distance D3, and the second distance D2 may also be the same as the fourth distance D4, and there is no strict limitation on this.

[0168] It can be understood that, since the first distance D1 from the second hollow area Q2 to the first wall 434 is different from the third distance D3 from the second hollow area Q2 to the first wall 434, the first distance D1 from the second hollow area Q2 to the first wall 434 is different from the third distance D3 from the second hollow area Q2 to the first wall 434. Therefore, the first hollow area Q1 and the second hollow area Q2 are not arranged end to end, but are arranged in a stepped manner with a gradient difference. In addition, since the second hollow areas Q2 and the third hollow areas Q3 are arranged alternately in a plurality of second hollow areas Q2 and a plurality of third hollow areas Q3, the arrangement of the plurality of second hollow areas Q2 and the plurality of third hollow areas Q3 is an S-shaped hollow arrangement as a whole. In this configuration, since the transition portion 43 has a plurality of hollowed-out areas, and the hollowed-out areas are arranged in an S-shaped hollowed-out arrangement, the remaining solid structure in the transition portion 43 of the reinforcing piece 40 can present a spring-like shape, so that the transition portion 43 of the reinforcing piece 40 has better tensile ductility during the bending process. As a result, the transition portion 43 as a whole can reduce the structural strength and improve the tensile ductility while meeting the bending requirements (such as the transition portion 43 will not break during the bending process).

[0169] For example, the transition portion 43 of the reinforcing member 40 may be hollowed out in an S-shape by punching and etching. The second hollow area Q2 and the third hollow area Q3 may be in the shape of a strip. It should be noted that the present embodiment does not impose strict restrictions on the number, shape, size, etc. of the second hollow area Q2 and the third hollow area Q3.

[0170] In a possible implementation, Fig.23aAs shown, along the Y direction, one end of the second hollow area Q2 penetrates the first wall 434, and the other end of the second hollow area Q2 is spaced apart from the second wall 435. One end of the third hollow area Q3 is spaced apart from the first wall 434, and the other end of the third hollow area Q3 penetrates the second wall 435. Under this arrangement, the hollowing process of the transition part 43 can be started from the side wall of the transition part 43, or the hollowing process of the transition part 43 can be terminated at the side wall of the transition part 43, so that the side wall of the transition part 43 can be used as the starting line or the ending line of the hollowing process.

[0171] In another possible implementation, Figure 23b As shown, along the Y direction, one end of the second hollow area Q2 is spaced from the first wall 434, and the other end of the second hollow area Q2 is spaced from the second wall 435. One end of the third hollow area Q3 is spaced from the first wall 434, and the other end of the third hollow area Q3 is spaced from the second wall 435.

[0172] Fourth embodiment:

[0173] Please refer to Fig.25a , Fig.25b , Fig.26a and Figure 26b , Fig.25a yes Figure 3 The reinforcing member 40 of the fourth embodiment of the driving motor 100 is a schematic structural diagram at an angle in a natural state, Fig.25b yes Figure 3 The reinforcing member 40 of the fourth embodiment of the driving motor 100 is a schematic structural diagram at an angle in an extended state, Fig.26a yes Fig.25a The fourth embodiment is shown in a schematic diagram of the assembly of the reinforcing member 40 and the circuit board 30 at an angle after the circuit board 30 is bent. Figure 26b yes Fig.25a The reinforcing member 40 of the fourth embodiment is shown as a schematic diagram of assembly with the circuit board 30 at another angle after the circuit board 30 is bent.

[0174] In this embodiment, the same contents as those in the first embodiment are not repeated. The difference from the first embodiment is that the transition portion 43 of the reinforcement member 40 is closer to the carrier 20 relative to the first connection portion 34 of the circuit board 30, and the transition portion 43 of the reinforcement member 40 is passed through by at least a portion of the first connection portion 34 of the circuit board 30.

[0175] It is understandable that, since the transition portion 43 of the reinforcing piece 40 is closer to the carrier 20 relative to the first connection portion 34 of the circuit board 30, and the transition portion 43 of the reinforcing piece 40 is penetrated by at least a portion of the first connection portion 34 of the circuit board 30, an avoidance through hole is provided in the transition portion 43 of the reinforcing piece 40 for the first connection portion 34 of the circuit board 30 to pass through. On the one hand, the transition portion 43 of the reinforcing piece 40 is penetrated by at least a portion of the first connection portion 34 of the circuit board 30, so that at least a portion of the first connection portion 34 of the circuit board 30 is located on the side of the transition portion 43 of the reinforcing piece 40 away from the carrier 20, so that the bending of the transition portion 43 of the reinforcing piece 40 can effectively avoid the bending of the first connection portion 34 of the circuit board 30, and avoid the transition portion 43 of the reinforcing piece 40 from squeezing the circuit board 30 during the bending process, so that the circuit board 30 synchronously squeezes the carrier 20, resulting in interference with the motion trajectory of the carrier 20, and the reliability is better. On the other hand, the transition portion 43 of the reinforcement 40 is passed through by at least a portion of the first connection portion 34 of the circuit board 30, which can not only provide good support and reinforcement for the circuit board 30, but also improve the interference stratification between the circuit board 30 and the reinforcement 40, which is beneficial to ensuring the assembly accuracy of the drive motor 100 and the working performance of the drive motor 100.

[0176] Please refer to Fig.25a , Fig.25b , Fig.26a and Figure 26b In this embodiment, the second extension portion 42 of the reinforcing piece 40 can be bent relative to the first extension portion 41 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40 (i.e., the first extension portion 41 of the reinforcing piece 40 can be bent relative to the second extension portion 42 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40). The bending and protruding direction of the transition portion 43 of the reinforcing piece 40 is the direction away from the carrier 20, and the bending and protruding direction of the first connecting portion 34 of the circuit board 30 is also the direction away from the carrier 20. In other words, the bending center line of the transition portion 43 of the reinforcing piece 40 and the bending center line of the first connecting portion 34 of the circuit board 30 are located on the same side of the first connecting portion 34 of the circuit board 30. Among them, the bending angle of the transition portion 43 of the reinforcing piece 40 is not limited, and it can be selected according to actual application conditions.

[0177] Furthermore, the bending length of the transition portion 43 of the reinforcing member 40 is the same as the bending length of the first connecting portion 34 of the circuit board 30. The bending length of the transition portion 43 refers to the extension length between the two ends of the transition portion 43 (one end connected to the first extension portion 41 and one end connected to the second extension portion 42). The bending length of the first connecting portion 34 refers to the extension length between the two ends of the first connecting portion 34 (one end connected to the first board body 31 and one end connected to the second board body 32).

[0178] It is understandable that, since the second extension portion 42 of the reinforcing piece 40 can be bent relative to the first extension portion 41 of the reinforcing piece 40 through the transition portion 43 of the reinforcing piece 40, when the second extension portion 42 of the reinforcing piece 40 is bent relative to the first extension portion 41 of the reinforcing piece 40, the transition portion 43 of the reinforcing piece 40 is bent and connected between the second extension portion 42 of the reinforcing piece 40 and the first extension portion 41 of the reinforcing piece 40. The bending length of the transition portion 43 of the reinforcing piece 40 is the same as the bending length of the first connecting portion 34 of the circuit board 30, which can reduce or eliminate the tensile force applied to the transition portion 43 of the reinforcing piece 40 by the first extension portion 41 and the second extension portion 42 at both ends of the transition portion 43 of the reinforcing piece 40 during the bending process, thereby preventing the transition portion 43 of the reinforcing piece 40 from being broken due to stretching during the bending process, and optimizing the stress concentration problem of the transition portion 43 of the reinforcing piece 40. In addition, the reinforcing piece 40 can be prevented from squeezing the circuit board 30 during the bending process, so that the circuit board 30 and the reinforcing piece 40 can have a better fit, and the interference and delamination problem between the circuit board 30 and the reinforcing piece 40 can be effectively improved.

[0179] Please refer to Fig.25a , Fig.25b , Fig.26a and Figure 26b In this embodiment, the transition portion 43 of the reinforcing member 40 may include a straight segment 436, a first bent segment 437, and a second bent segment 438. The extension direction of the straight segment 436 of the transition portion 43 intersects with the extension direction of the first extension portion 41 and the extension direction of the second extension portion 42. The first bent segment 437 of the transition portion 43 is bent and connected between the first extension portion 41 and one end of the straight segment 436 of the transition portion 43, and the bending and protruding direction of the first bent segment 437 of the transition portion 43 is the direction facing away from the carrier 20. The second bent segment 438 of the transition portion 43 is bent and connected between the other end of the straight segment 436 of the transition portion 43 and the second extension portion 42, and the bending and protruding direction of the second bent segment 438 of the transition portion 43 is the direction facing away from the carrier 20.

[0180] The transition portion 43 may have a fourth hollow area Q4, which is located at one or more of the straight line segment 436, the first bending segment 437 and the second bending segment 438. At least part of the first connection portion 34 of the circuit board 30 passes through the fourth hollow area Q4, and the first connection portion 34 extending out of the fourth hollow area Q4 protrudes toward the inner surface of the shell 10.

[0181] For example, the transition portion 43 of the reinforcing member 40 may be hollowed out by punching and etching. The fourth hollowed-out area Q4 may be in the shape of a bar. It should be noted that this embodiment does not impose strict restrictions on the number, shape, size, etc. of the fourth hollowed-out area Q4. In other embodiments, the straight line segment 436 may also be a curved line segment.

[0182] It is understandable that, since the transition portion 43 of the reinforcing piece 40 has two bending sections, the transition portion 43 of the reinforcing piece 40 is actually bent twice. By bending the transition portion 43 of the reinforcing piece 40 twice, the reinforcing piece 40 and the circuit board 30 can be kept the same bending length while avoiding the circuit board 30, thereby optimizing the stress concentration problem of the transition portion 43 of the reinforcing piece 40, and improving the problem of the circuit board 30 interfering with the motion trajectory of the carrier 20 due to the reinforcing piece 40 squeezing the circuit board 30, thereby reducing the adverse effects on the circuit board 30 and the carrier 20, and achieving better reliability.

[0183] The embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
