[0002] The present application relates to the field of camera technology, and in particular to a motor, a camera module and an electronic device. BACKGROUND

[0003] Electronic devices usually have a camera module to take pictures. When taking pictures or videos, the camera module may shake due to external vibrations, affecting the image quality on the image sensor.

[0004] Many anti-shake technologies have appeared on the market, such as optical image stabilization (OIS), which is based on the collected shaking stroke, and drives the lens to move in the opposite direction in the plane perpendicular to the optical axis through the OIS motor to offset the shaking amount and achieve anti-shake. However, when the traditional motor drives the lens to move in one direction, the lens will also produce an additional displacement in other directions, the control precision of optical image stabilization driving is low, and the reliability of the motor is poor. SUMMARY

[0005] The present application provides a motor, a camera module and an electronic device. The motor has high reliability and control precision. The camera module and the electronic device have better imaging effect.

[0006] In a first aspect, the embodiments of the present application provide a motor. The motor comprises a base, an anti-shake bracket, a first anti-shake driving mechanism, a second anti-shake driving mechanism and at least four reeds; the anti-shake bracket is movably connected to the base, the first anti-shake driving mechanism connects the base and the anti-shake bracket, and is used to drive the anti-shake bracket to move relative to the base along a first direction, the second anti-shake driving mechanism connects the base and the anti-shake bracket, and is used to drive the anti-shake bracket to move relative to the base along a second direction, the second direction intersects the first direction; each reed comprises a first fixed end and a second fixed end, the first fixed end of each reed is fixedly connected to the anti-shake bracket, and the second fixed end is fixedly connected to the base, two reeds of the at least four reeds form a first pair, and the other two reeds form a second pair, the arrangement direction of each reed of the first pair is parallel to the first direction, the arrangement direction of each reed of the second pair is parallel to the second direction, and the arrangement direction of the reed is the direction of the first fixed end of the reed pointing to the second fixed end; the connecting line of the two reeds of the first pair is a first connecting line, the connecting line of the two reeds of the second pair is a second connecting line, and the first connecting line intersects the second connecting line.

[0007] In the embodiments of the present application, the reeds can be used to provide an elastic force to move the anti-shake support back to the balance position when the anti-shake support moves relative to the base and deviates from the balance position. The two reeds of the first pair can include a first reed and a third reed, and the two reeds of the second pair can include a second reed and a fourth reed. By arranging the direction of each reed of the first pair parallel to the first direction and the direction of each reed of the second pair parallel to the second direction, when the anti-shake support moves relative to the base along the first direction, the first reed and the third reed can deform along the first direction, and the first reed and the third reed can provide an elastic force along the first direction to the anti-shake support, so that the anti-shake support can return to the balance position; the second reed and the fourth reed can provide a force along the second direction to the anti-shake support, and the direction of the force provided by the second reed to the anti-shake support is opposite to the direction of the force provided by the fourth reed to the anti-shake support, and the resultant force can be zero, so that the second reed and the fourth reed can limit the displacement of the anti-shake support in the second direction, so that the anti-shake support can displace relative to the base along the first direction, and the anti-shake support is not easy to deviate, that is, accurate guidance can be achieved during the movement of the anti-shake support relative to the base along the first direction, which is beneficial to improve the reliability and control accuracy of the motor.

[0008] When the anti-shake support moves relative to the base along the second direction, the second reed and the fourth reed can deform along the second direction, and the second reed and the fourth reed can provide an elastic force along the first direction to the anti-shake support, so that the anti-shake support can return to the balance position; the first reed and the third reed can provide a force along the first direction to the anti-shake support, and the direction of the force provided by the first reed to the anti-shake support is opposite to the direction of the force provided by the third reed to the anti-shake support, and the resultant force can be zero, so that the first reed and the third reed can limit the displacement of the anti-shake support in the first direction, so that the anti-shake support can displace relative to the base along the second direction, and the anti-shake support is not easy to deviate, that is, accurate guidance can be achieved during the movement of the anti-shake support relative to the base along the second direction, which is beneficial to improve the reliability and control accuracy of the motor.

[0009] In the embodiments of the present application, the motor can cooperate with the first reed, the second reed, the third reed and the fourth reed, so as to guide the anti-shake support in the first direction and the second direction, and the guidance in the two directions is not easy to interfere. Based on the guidance of the first reed and the third reed, the anti-shake support can move relative to the base along the first direction; based on the guidance of the second reed and the fourth reed, the anti-shake support can move relative to the base along the second direction, so that the motor can realize accurate guidance in the optical anti-shake process through the cooperation of the base, the first reed, the second reed, the third reed, the fourth reed and the anti-shake support.

[0010] In a possible implementation, the planes in which the leaf springs are located are perpendicular to the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0011] It can be understood that, in the embodiment, the planes in which the leaf springs are located can be parallel to the arrangement plane of the anti-shake support, for example, the leaf springs can be arranged in the X-Y plane. The leaf springs can be arranged by using the space on one side of the anti-shake support, and the motor structure is relatively compact. In addition, when the anti-shake support moves relative to the base in the X-Y plane, the leaf springs can provide a force to move the anti-shake support back to the balance position, and can limit the displacement of the anti-shake support in the third direction to a certain extent.

[0012] In a possible implementation, the two leaf springs of the same pair are centrally symmetrically distributed relative to the center of the anti-shake support.

[0013] It can be understood that, in the embodiment, the two leaf springs of the same pair being centrally symmetrically distributed relative to the center of the anti-shake support means that the positions and structures of the two leaf springs of the same pair can be centrally symmetrically distributed relative to the center of the anti-shake support, or the positions of the two leaf springs of the same pair can be centrally symmetrically distributed relative to the center of the anti-shake support, and the structures of the two leaf springs of the same pair can not be centrally symmetrically distributed relative to the center of the anti-shake support. By arranging the two leaf springs of the same pair to be centrally symmetrically distributed relative to the center of the anti-shake support, when the anti-shake support moves relative to the base, the moment of the resultant force provided by the two leaf springs of the same pair to the anti-shake support can be zero, and displacement of the anti-shake support relative to the base in a direction other than the movement direction can be avoided, so that more accurate guidance is achieved during movement of the anti-shake support relative to the base, and the reliability and control accuracy of the motor are improved.

[0014] For example, when the anti-shake support moves relative to the base in the second direction, the moment of the resultant force provided by the first leaf spring and the third leaf spring to the anti-shake support can be zero, so that displacement of the anti-shake support relative to the base in a direction other than the second direction can be avoided, so that more accurate guidance is achieved during movement of the anti-shake support relative to the base in the first direction. For another example, when the anti-shake support moves relative to the base in the first direction, the moment of the resultant force provided by the second leaf spring and the fourth leaf spring to the anti-shake support can be zero when the second leaf spring and the fourth leaf spring guide the anti-shake support by cooperating with each other, so that displacement of the anti-shake support relative to the base in a direction other than the first direction can be avoided, so that more accurate guidance is achieved during movement of the anti-shake support relative to the base in the first direction.

[0015] In a possible implementation, the first fixed ends of the two pairs of leaf springs are fixed to the four corner portions of the anti-shake support in a one-to-one correspondence, and the second fixed ends of the two pairs of leaf springs are connected to the four positions of the base in a one-to-one correspondence. In this way, the four leaf springs do not occupy too much space above the anti-shake support, the positions of the four leaf springs are arranged more reasonably, and the space utilization rate of the motor is improved.

[0016] In a possible implementation, the base includes a bottom plate and four convex columns, the bottom plate includes oppositely arranged first and second surfaces, the first surface faces the anti-shake support, and the four convex columns are fixedly connected to the first surface.

[0017] In the embodiment, the four convex columns are arranged such that the planes in which the four springs are located are all perpendicular to the third direction, and the four springs are correspondingly arranged at the four corners of the anti-shake support and are all located on the side of the anti-shake support facing away from the bottom plate of the base. The motor has a simple structure and high space utilization.

[0018] In a possible implementation, the spring further includes a connecting section, the connecting section is connected between the first fixed end and the second fixed end, and the connecting section is in a bent shape.

[0019] In the embodiment, the connecting section of the spring is easily deformed after being extruded or stretched, so that the spring can provide an elastic force for moving the anti-shake support back to the balanced position when the anti-shake support moves relative to the base. It can be understood that the two springs in the first pair are easily deformed in the first direction, and the two springs in the second pair are easily deformed in the second direction, so that the two springs in the first pair provide an elastic force in the first direction for the anti-shake support, and the two springs in the second pair provide an elastic force in the second direction for the anti-shake support when the anti-shake support moves relative to the base.

[0020] In a possible implementation, the motor further includes a plurality of balls, and the anti-shake support is movably connected to the base through the plurality of balls.

[0021] In the embodiment, the anti-shake support and the focusing support are movably connected through the plurality of balls, which can reduce the frictional resistance between the balls and the anti-shake support while ensuring that sufficient supporting force is provided, and improve the smoothness of the movement of the anti-shake support in movably connecting the base. In addition, the plurality of balls can provide multi-point support for the anti-shake support, which is conducive to dispersing stress and preventing deformation of the balls due to excessive concentration of stress in a single direction when the balls are subjected to impact, thereby improving the reliability of the plurality of balls in supporting the anti-shake support and other structural members.

[0022] In a possible implementation, the base is provided with a plurality of rolling grooves, the openings of the rolling grooves face the anti-shake support, the number of the plurality of balls is a plurality, and the plurality of groups of balls are correspondingly arranged in the plurality of rolling grooves; the anti-shake support includes a first side portion, the first side portion has a central axis parallel to the first direction, and the plurality of rolling grooves include a first rolling groove, the first rolling groove is arranged opposite to the first side portion, and the center of the first rolling groove is located on a first side of the central axis along the second direction, the first side of the central axis being close to the center of the anti-shake support.

[0023] It can be understood that the anti-shake support is affected by the friction torque between the anti-shake support and each ball group during movement. The friction torque is positively correlated with the force arm of each friction force. The force arm of each friction force is the distance from the center of each ball group to the center of the anti-shake support. In the embodiment, by setting the center of the rolling groove close to the center of the anti-shake support, the force arm of the corresponding ball group can be reduced, thereby reducing the influence of the friction torque between the anti-shake support and the ball group on the anti-shake support, and facilitating to improve the response rate of the motor and the anti-shake effect when the anti-shake support is movably connected to the base through the ball group.

[0024] In a possible implementation, the anti-shake support further includes a support body and a metal insert, a part of the metal insert is embedded in the support body, and a part of the metal insert is exposed relative to the support body and in contact with the ball group.

[0025] In the embodiment, the metal insert can improve the overall strength of the anti-shake support. By setting the metal insert in contact with the ball group, the anti-shake support can be prevented from being deformed under pressure, and the frictional resistance during rolling of the ball group can also be reduced.

[0026] In a possible implementation, the first anti-shake driving mechanism includes a first anti-shake coil and a first anti-shake magnetic piece, the first anti-shake coil is fixedly connected to the base, the first anti-shake magnetic piece is fixedly connected to the anti-shake support, and the first anti-shake coil faces the first anti-shake magnetic piece.

[0027] In the embodiment, the first anti-shake coil is arranged to face the first anti-shake magnetic piece, for driving the anti-shake support to move relative to the base along the first direction, and the first anti-shake magnetic piece and the first anti-shake coil can be arranged in the third direction. The first anti-shake coil is arranged to face the first anti-shake magnetic piece, which means that the winding plane of the first anti-shake coil faces the first anti-shake magnetic piece. For example, the winding plane of the first anti-shake coil can be arranged perpendicular to the third direction, and at this time, the first anti-shake coil can be arranged horizontally, which is conducive to reducing the size of the motor in the third direction and realizing miniaturization of the motor. In addition, the first anti-shake driving mechanism is designed as a moving magnet, and the magnetic gap width of the first anti-shake driving mechanism is not easy to change during movement of the anti-shake support relative to the base for optical anti-shake, which is conducive to ensuring the driving accuracy of the motor.

[0028] In a possible implementation, the second anti-shake driving mechanism includes a second anti-shake coil and a second anti-shake magnetic piece, the second anti-shake coil is fixedly connected to the base, the second anti-shake magnetic piece is fixedly connected to the anti-shake support, and the second anti-shake coil faces the second anti-shake magnetic piece.

[0029] In the embodiment, the second anti-shake coil is arranged facing the second anti-shake magnetic member, and is configured to drive the anti-shake support to move relative to the base along the second direction. The second anti-shake magnetic member and the second anti-shake coil are arranged along the third direction. It can be understood that the second anti-shake coil is arranged facing the second anti-shake magnetic member means that the winding plane of the second anti-shake coil faces the second anti-shake magnetic member. For example, the winding plane of the second anti-shake coil can be arranged perpendicular to the third direction, and in this case, the second anti-shake coil can be arranged horizontally, which is conducive to reducing the size of the motor along the third direction and achieving miniaturization of the motor. In addition, the second anti-shake driving mechanism is a moving magnet design, and the magnetic gap width of the second anti-shake driving mechanism is not easy to change during the movement of the anti-shake support relative to the base for optical anti-shake, which is conducive to ensuring the driving accuracy of the motor.

[0030] In a possible implementation, the motor further includes a first anti-shake magnetic member fixed to the base and arranged facing the first anti-shake magnetic member. In this way, the first anti-shake magnetic member and the first anti-shake magnetic member can generate magnetic attraction force, so that the anti-shake support has a tendency to approach the base, thereby ensuring that the base, the ball group and the anti-shake support remain in contact, achieving pre-tightening, and improving the reliability of the optical anti-shake process of the motor.

[0031] In a possible implementation, the motor further includes a second anti-shake magnetic member fixed to the base and arranged facing the second anti-shake magnetic member. In this way, the second anti-shake magnetic member and the second anti-shake magnetic member can generate magnetic attraction force, so that the anti-shake support has a tendency to approach the base, thereby ensuring that the base, the ball group and the anti-shake support remain in contact, achieving pre-tightening, and improving the reliability of the optical anti-shake process of the motor.

[0032] In a possible implementation, the first anti-shake driving mechanism further includes a first position sensor fixed to the base and configured to detect a first magnetic field variation of the first anti-shake magnetic member when the anti-shake support moves along the first direction. It can be understood that the first position sensor can detect the position change of the anti-shake support along the first direction by detecting the first magnetic field variation of the first anti-shake magnetic member.

[0033] In a possible implementation, the second anti-shake driving mechanism further includes a second position sensor fixed to the base and configured to detect a second magnetic field variation of the second anti-shake magnetic member when the anti-shake support moves along the second direction. It can be understood that the second position sensor can detect the position change of the anti-shake support along the second direction by detecting the second magnetic field variation of the second anti-shake magnetic member.

[0034] In a possible implementation, the motor further includes a focusing support, a focusing coil, and a focusing magnetic piece; the focusing support is located at the inner side of the anti-shake support and movably connected to the anti-shake support; the focusing magnetic piece is fixed to the focusing support; the focusing coil is fixed to the anti-shake support and faces the focusing magnetic piece to drive the focusing support to move relative to the base along a third direction intersecting the first direction and the second direction.

[0035] It can be understood that, by arranging the focusing support at the inner side of the anti-shake support, the focusing coil fixed to the anti-shake support, and the focusing magnetic piece fixed to the focusing support, the optical anti-shake motor subassembly of the motor wraps the focusing motor subassembly. When the focusing support is located at the inner side of the anti-shake support, the anti-shake support can be arranged around the focusing support. The arrangement around can be that the anti-shake support is arranged around the focusing support once, or that a part of the anti-shake support is arranged around the focusing support.

[0036] It can be understood that, in some solutions, the anti-shake support is located at the inner side of the focusing support. At this time, when the camera module needs to focus, the focusing support needs to drive the anti-shake support and the lens to move along the third direction. Thus, the weight of the motor composed of the focusing support, the anti-shake support, and the lens is heavy, thereby causing the focusing drive assembly to need to increase the driving force by increasing the volume. Therefore, this arrangement is not conducive to the lightweight and small-size design of the motor. In the embodiment, the focusing support is arranged at the inner side of the anti-shake support. At this time, when the camera module needs to focus, the focusing support needs to drive the lens to move along the third direction. Thus, the motor in the focusing process can omit the anti-shake support, that is, the weight of the motor composed of the focusing support and the lens is light, thereby being conducive to the small-size design of the focusing drive assembly. The motor in the embodiment can achieve the lightweight and small-size design.

[0037] It can be understood that, compared with the solution in which the anti-shake support is at the inner side of the focusing support, the anti-shake support needs at least two anti-shake drive assemblies to drive the anti-shake support to move in the X-Y plane. Thus, the motor needs to arrange at least two sets of lines to provide signals and power supply for the anti-shake drive assemblies. Moreover, the at least two sets of lines need to pass through the focusing support. Therefore, the power supply arrangement of this solution is relatively complex, thereby increasing the difficulty of the motor arrangement. In the embodiment, the focusing support is arranged at the inner side of the anti-shake support. Since the focusing support needs one focusing drive assembly to drive the focusing support to move along the third direction, the motor needs one set of lines to provide signals and power supply for the focusing drive assembly, that is, one set of lines needs to pass through the anti-shake support. Therefore, the power supply arrangement of the solution in the embodiment is relatively simple, thereby greatly reducing the difficulty of the motor arrangement.

[0038] The plane in which the wires of the focusing coil are wound can be parallel to the third direction. In this case, the focusing coil is arranged vertically, so that the focusing coil can occupy a smaller area in the plane perpendicular to the optical axis, thereby facilitating the miniaturization of the motor. The focusing magnetic member can include two opposite polarity directions, both of which are perpendicular to the third direction. In this case, the focusing magnetic member can be arranged vertically, thereby reducing the occupied space of the focusing magnetic member in the motor and facilitating the miniaturization design of the motor.

[0039] In a possible implementation, the motor further includes a guide rod and a sliding groove, the guide rod is fixedly connected to one of the anti-shake bracket and the focusing bracket, the sliding groove is arranged on the other one of the anti-shake bracket and the focusing bracket, at least part of the guide rod is located in the sliding groove, and the focusing bracket is slidably connected to the anti-shake bracket through the guide rod and the sliding groove.

[0040] In the embodiment, the focusing bracket is slidably connected to the anti-shake bracket through the cooperation of the guide rod and the sliding groove, so that the focusing bracket has good stability during movement relative to the anti-shake bracket, thereby facilitating the large-stroke design of the focusing function of the motor. In addition, the guide rod can also be used to bear the focusing bracket, thereby facilitating the large-load design of the focusing function of the motor.

[0041] In a possible implementation, the guide rod includes a first guide rod and a second guide rod arranged at intervals, and the first guide rod and the second guide rod are located on two sides of the focusing magnetic member respectively; the sliding groove includes a first sliding groove and a second sliding groove, part of the first guide rod is located in the first sliding groove, the first sliding groove includes a first groove wall and a second groove wall, the first groove wall and the second groove wall are arranged at an angle, and the first groove wall and the second groove wall are both in contact with the first guide rod; part of the second guide rod is located in the second sliding groove, the second sliding groove includes a third groove wall, the plane in which the third groove wall is located intersects the planes in which the first groove wall and the second groove wall are located, and the third groove wall is in contact with the second guide rod.

[0042] In the embodiment, the first sliding groove can be a “V”-shaped groove, the first groove wall and the second groove wall of the first sliding groove are in contact with the first guide rod, so that the first guide rod is tightly fitted with the first sliding groove. The second sliding groove can be a “U”-shaped groove or a “L”-shaped groove, the third groove wall of the second sliding groove is in contact with the second guide rod, so that the second guide rod is loosely fitted with the second sliding groove. In this way, the cooperation between the guide rod and the focusing bracket includes tight fitting and loose fitting, thereby reducing the assembly difficulty between the guide rod and the focusing bracket.

[0043] In a possible implementation, the surface of the guide rod is provided with a lubricating film. In this way, the friction coefficient between the guide rod and the sliding groove can be reduced during the sliding of the guide rod relative to the sliding groove, so that the movement of the focusing bracket relative to the anti-shake bracket along the third direction is smoother.

[0044] In a possible implementation, the groove wall of the sliding groove is provided with a lubricating film. In this way, the friction coefficient between the guide rod and the sliding groove can be reduced during the sliding of the guide rod relative to the sliding groove, so that the movement of the focusing support relative to the anti-shake support along the third direction is smoother.

[0045] In a possible implementation, the motor further includes a focusing magnetic attraction piece, which is fixed to the base and faces the focusing magnetic piece. In this way, the focusing magnetic attraction piece and the focusing magnetic piece can generate a magnetic attraction force, so that the focusing support has a tendency to approach the anti-shake support, thereby ensuring that the guide rod and the sliding groove are in contact, pre-tightening is achieved, and the reliability of the focusing process of the motor is improved.

[0046] In a possible implementation, the motor further includes a focusing magnetic attraction piece, which is fixed to the base and faces the focusing magnetic piece. In this way, the focusing magnetic attraction piece and the focusing magnetic piece can generate a magnetic attraction force, so that the focusing support has a tendency to approach the anti-shake support, thereby ensuring that the guide rod and the sliding groove are in contact, pre-tightening is achieved, and the reliability of the focusing process of the motor is improved.

[0047] In a possible implementation, the motor further includes a focusing magnetic attraction piece, which is fixed to the base and faces the focusing magnetic piece. In this way, the focusing magnetic attraction piece and the focusing magnetic piece can generate a magnetic attraction force, so that the focusing support has a tendency to approach the anti-shake support, thereby ensuring that the guide rod and the sliding groove are in contact, pre-tightening is achieved, and the reliability of the focusing process of the motor is improved.

[0048] It can be understood that, compared with the scheme of fixing the motor on the filter support, the motor and the filter support are both fixed on the module circuit board in this embodiment, so that the motor and the filter support can be arranged staggered in the X-Y plane, thereby greatly reducing the height of the camera module and facilitating the miniaturization of the camera module.

[0049] In a possible implementation, the motor further includes a focusing magnetic attraction piece, which is fixed to the base and faces the focusing magnetic piece. In this way, the focusing magnetic attraction piece and the focusing magnetic piece can generate a magnetic attraction force, so that the focusing support has a tendency to approach the anti-shake support, thereby ensuring that the guide rod and the sliding groove are in contact, pre-tightening is achieved, and the reliability of the focusing process of the motor is improved.

[0082] The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0083] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited otherwise, the terms "mount", "connect" should be interpreted broadly, for example, "connect" can be detachable connection, or can be non-detachable connection, can be direct connection, or can be indirect connection through intermediate medium.

The camera module 100 can be a rear camera module 100 or a front camera module 100. It can be understood that FIG. 1 and the relevant drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1 and the drawings below. In addition, when the electronic device 1000 is some other form of device, the electronic device 1000 can also not include the screen 300.

[0094] The device housing 200 can include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 can be fixedly connected to the frame 201 by means of adhesive, clamping, etc. The back cover 202 can also be an integrally formed structure with the frame 201, i.e., the back cover 202 and the frame 201 are an integral structure.

[0095] In some embodiments, the screen 300 can be located at a side of the frame 201 away from the back cover 202. At this time, the screen 300 and the back cover 202 can be located at two sides of the frame 201 respectively. The screen 300, the frame 201 and the back cover 202 jointly enclose the inside of the electronic device 1000. The inside of the electronic device 1000 can be used to place devices of the electronic device 1000, such as a battery, a receiver or a microphone, etc. The screen 300 can be a flat screen or a curved screen.

[0096] For example, the camera module 100 can be located in the inside of the electronic device 1000. The camera module 100 can be located at a side of the screen 300 facing the back cover 202. The back cover 202 can be provided with a light-transmitting portion 203. The shape of the light-transmitting portion 203 is not limited to the circular shape shown in FIG. 1. The light-transmitting portion 203 connects the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting portion 203. The camera module 100 can collect the light entering the inside of the electronic device 1000.

[0097] Please refer to FIG. 3 and FIG. 4, FIG. 3 is a structural schematic diagram of some embodiments of the camera module 100 shown in FIG. 1, and FIG. 4 is a partially exploded schematic diagram of some embodiments of the camera module 100 shown in FIG. 3.

[0098] In some embodiments, the camera module 100 includes a motor 1, a lens 2, a module circuit board 3, an image sensor 4, a filter holder 5, a filter 6 and a substrate 7. The image sensor 4 is also called a photosensitive chip or a photosensitive element. The image sensor 4 is used to collect ambient light and convert image information carried by the ambient light into an electrical signal.

[0099] It can be understood that the camera module 100 can also include fewer or more structures. For example, the camera module 100 can include fewer structures. For example, the camera module 100 can not include the filter holder 5, and / or the filter 6, and / or the substrate 7.

[0100] It can be understood that hereinafter, in order to facilitate description, the length direction of the camera module 100 is defined as the X-axis direction, the width direction of the camera module 100 is defined as the Y-axis direction, and the height direction of the camera module 100 is defined as the Z-axis direction. The X-axis direction can be a first direction, the Y-axis direction can be a second direction, and the Z-axis direction can be a third direction. It can be understood that the first direction, the second direction and the third direction are perpendicular to each other.

[0101] Please refer to FIG. 5, FIG. 5 is a partially sectional schematic diagram of the camera module 100 shown in FIG. 3 along B-B in some embodiments.

[0102] In some embodiments, the module circuit board 3 can be fixed on the substrate 7, and the substrate 7 can be used to support other structural members of the camera module 100. The image sensor 4 can be disposed on the module circuit board 3 and electrically connected to the module circuit board 3. At this time, the image sensor 4 and the module circuit board 3 can transmit signals to each other.

[0103] For example, the filter holder 5 is fixedly connected to the module circuit board 3. The filter holder 5 and the image sensor 4 are located on the same side of the module circuit board 3. The filter holder 5 can be located on the inner side of the motor 1. The filter holder 5 is provided with a light passing hole 510. The filter 6 is fixedly connected to the filter holder 5. The filter 6 can be located in the light passing hole 510. The filter 6 is also disposed opposite to the image sensor 4. The filter 6 can be used to filter infrared light or blue light and the like in the light entering the image sensor 4 before the light enters the image sensor 4, so as to ensure that the image sensor 4 has better imaging quality.

[0104] For example, the motor 1 can be fixed on the module circuit board 3. The motor 1 and the filter 6 can be located on the same side of the module circuit board 3. The lens 2 is mounted on the motor 1. The image sensor 4 is located on the light exit side of the lens 2. It can be understood that, in the third direction (i.e. the Z-axis direction), the lens 2, the filter 6 and the image sensor 4 are arranged in sequence. At this time, the image sensor 4 is located on the light exit side of the lens 2. The filter 6 is located between the lens 2 and the image sensor 4. The lens 2 can be used to collect ambient light. The optical axis direction of the lens 2 can be parallel to the third direction of the camera module 100. The optical axis direction of the lens 2 and the optical axis direction of the camera module 100 can be the same direction.

[0105] It can be understood that, compared with the scheme of fixing the motor 1 on the filter holder 5, the motor 1 is fixed on the module circuit board 3 in the present embodiment, so that the motor 1 and the filter holder 5 can be arranged staggered in the X-Y plane in the Z-axis direction, thereby greatly reducing the height of the camera module 100, which is conducive to the miniaturization of the camera module 100.

[0106] It can be understood that the motor 1 can be an auto focus motor 1. In this way, the motor 1 can control the lens 2 to move along the third direction (i.e., the Z-axis direction) to realize auto focus (AF). The motor 1 can also be an anti-shake motor 1. In this way, the motor 1 can control the lens 2 to move along a plane perpendicular to the third direction (i.e., the X-Y plane). When the camera module 100 collects ambient light, if the electronic device 1000 is subjected to external force and generates shaking in the X-Y plane, the motor 1 can control the lens 2 to move in the X-Y plane to offset the shaking stroke of the lens 2 in the X-Y plane, so as to avoid or reduce the position offset of the lens 2 caused by shaking. In other words, the camera module 100 of the present application can control the lens 2 to move in the X-Y plane by the motor 1 to realize optical image stabilization (OIS) of the camera module 100, and improve the imaging quality of the camera module 100. The motor 1 can also be an anti-shake and auto focus integrated motor 1. In this way, the motor 1 can control the lens 2 to realize auto focus and optical image stabilization. The present embodiment is described by taking the motor 1 as an anti-shake and auto focus integrated motor 1 as an example.

[0107] The structure of the camera module 100 is generally introduced above in combination with the related drawings. The structure of the motor 1 will be specifically introduced below in combination with the related drawings.

In other examples, the circuit board assembly 43 can also not include the focus sensor 433 and / or the focus magnetic attraction piece 434.

[0112] In some embodiments, the housing 50 can include a top plate 51 and a side frame 52 connected to the periphery of the top plate 51. In the present embodiment, the side frame 52 and the top plate 51 can be an integrally formed structure. In other embodiments, the side frame 52 can also be connected to the periphery of the top plate 51 by other processes (such as welding, bonding, or buckling, etc.). Exemplarily, the top plate 51 can be provided with a raised area 511 and a through hole 512 penetrating the raised area 511 of the top plate 51 in the third direction Z. It can be understood that the raised area 511 can be used to avoid the lens 2 when the lens moves in the third direction.

[0113] In some embodiments, the housing 50 can be assembled with the base 10, and the housing 50 can be covered on the base 10, and the housing 50 and the base 10 cooperate to encapsulate and protect the internal structure of the motor 1. Exemplarily, part of the structure of the motor 1 can be exposed through the through hole 512 of the housing 50, for example, part of the structure of the focus bracket 41 is exposed. The lens 2 can be mounted on the focus bracket 41, and part of the lens 2 can extend out to the outside of the motor 1 through the through hole 512.

[0130] Exemplarily, the first extension portion 133 and the second extension portion 134 can be arranged on different first conductive portions 131. In other embodiments, the first extension portion 133 and the second extension portion 134 can also be arranged on the same first conductive portion 131.

[0131] Please refer to FIGS. 7-9, FIG. 8 is a structural schematic diagram of the base 10 shown in FIG. 7 in another angle in some embodiments, and FIG. 9 is a partial cross-sectional structural schematic diagram of the base 10 shown in FIG. 8 along C-C in some embodiments.

[0132] In some embodiments, the reinforcing plate 12 can be mounted on the bottom plate 11 to improve the overall strength of the base 10, thereby facilitating the improvement of the reliability of the base 10. For example, the first edge 121a can be embedded in the first edge area 111a, the second edge 121b can be embedded in the second edge area 111b, the third edge 121c can be embedded in the third edge area 111c, and the fourth edge 121d can be embedded in the fourth edge area 111d.

The end of the second conductive part 132 can also be exposed relative to the second surface 11b and / or the third surface 11c of the base plate 11, for electrically connecting the module circuit board 3 (see FIG. 5). In other words, the conductive assembly 13 can be used as an electrical connection transmission channel between the structural members in the motor 1 and the module circuit board 3.

[0137] For example, the conductive assembly 13 is spaced apart from the reinforcing plate 12 to avoid interference with the electrical transmission process of the conductive assembly 13 when the reinforcing plate 12 contacts the conductive assembly 13, so as to ensure the reliability of the motor 1 while achieving miniaturization.

[0157] Please refer to FIGS. 12 to 14, and FIG. 14 is a structural schematic diagram of the anti-shake support 21 shown in FIG. 6 from another angle in some embodiments.

[0158] In some embodiments, the number of the metal inserts 212 can be three, and the three metal inserts 212 can include a first insert 212a, a second insert 212b, and a third insert 212c.

[0159] In some embodiments, a portion of the metal insert 212 can be embedded in the support body 211.

In the Z-axis direction, the first insert 212a can cover at least a portion of the bottom wall of the first recess 2119a. For example, a portion of the second insert 212b can be embedded at the connection between the second edge 211b and the third edge 211c, and a portion of the second insert 212b can be exposed relative to the second recess 2119b of the support body 211. In the Z-axis direction, the second insert 212b can cover at least a portion of the bottom wall of the second recess 2119b. For example, a portion of the third insert 212c can be embedded at the connection between the fourth edge 211d and the first edge 211a, and a portion of the third insert 212c can be exposed relative to the third recess 2119c of the support body 211.

[0160] In the present embodiment, a portion of the metal insert 212 embedded in the support body 211 can be an integrally formed structure with the support body 211 by means of insert-molding or the like. At this time, the metal insert 212 is embedded in the support body 211. In this way, the metal insert 212 can improve the overall strength of the anti-shake support 21. In other embodiments, the metal insert 212 can also be fixed in the corresponding recess 2119 by means of adhesion or the like.

[0163] Please refer to FIG. 15A and FIG. 15B, FIG. 15A is a partial structure schematic diagram of the motor 1 in some embodiments shown in FIG. 6, and FIG. 15B is a structure schematic diagram of the partial structure of the motor 1 shown in FIG. 15A from another angle.

[0164] In some embodiments, the first anti-shake magnetic member 222a can be installed in the first accommodating groove 2116a of the anti-shake bracket, and the second anti-shake magnetic member 222b can be installed in the second accommodating groove 2116b of the anti-shake bracket. At this time, the first anti-shake magnetic member 222a and the second anti-shake magnetic member 222b can be arranged in an L shape. For example, the first anti-shake magnetic member 222a and the second anti-shake magnetic member 222b can be arranged in the X-Y plane. The first anti-shake magnetic member 222a and the second anti-shake magnetic member 222b can be arranged at the two edge positions of the first edge 211a and the second edge 211b of the anti-shake bracket 21, which is conducive to the miniaturization of the motor 1 as a whole.

[0165] For example, the first anti-shake magnetic member 222a can include one or more magnets, and the implementation structure of the first anti-shake magnetic member 222a can be various. For example, the first anti-shake magnetic member 222a is a Halbach magnet array, which can include at least three magnets. In the three adjacent magnets, the polarity directions of the two magnets at the edges are opposite, and perpendicular to the arrangement direction of the three magnets, and the polarity direction of the magnet in the middle is from one magnet to another. In some other embodiments, the first anti-shake magnetic member 222a can adopt a double-magnet scheme, for example, composed of two magnets, which are arranged in the first direction and have opposite polarity directions. In some other embodiments, the first anti-shake magnetic member 222a can adopt a single-magnet scheme, for example, composed of one magnet, which includes two parts with opposite polarity directions. The magnet can be made by a double-pole magnetization process.

[0166] Exemplarily, the second anti-shake magnetic piece 222b can include one or more magnets, and the implementation structure of the second anti-shake magnetic piece 222b can be various. For example, the second anti-shake magnetic piece 222b is a Halbach magnet array. In some other embodiments, the second anti-shake magnetic piece 222b can adopt a double-magnet scheme. In some other embodiments, the second anti-shake magnetic piece 222b can adopt a single-magnet scheme.

[0167] Please refer to FIG. 16 and FIG. 17, FIG. 16 is a schematic diagram of the partial structure of the motor 1 shown in FIG. 6 in some embodiments, and FIG. 17 is a schematic diagram of the partial cross section of the motor 1 shown in FIG. 16 along D-D in some embodiments. Exemplarily, FIG. 16 mainly shows the assembly structure schematic diagram between the base 10, the anti-shake driving module 20 (including the anti-shake support 21, the first anti-shake driving mechanism, the second anti-shake driving mechanism 22b, and the ball group 23), the first spring piece, the second spring piece, the third spring piece, and the fourth spring piece.

[0168] In some embodiments, the first edge part 211a of the anti-shake support 21 corresponds to the first edge area 111a of the base 10, the second edge part 211b corresponds to the second edge area 111b, the third edge part 211c corresponds to the third edge area 111c, and the fourth edge part 211d corresponds to the fourth edge area 111d. Exemplarily, the first through hole 110 of the base 10 and the second through hole 2115 of the anti-shake support 21 at least partially overlap. In other words, the anti-shake support 21 and the base 10 can also be considered as coaxially nested, which is conducive to improving the compactness of the arrangement of the structural parts in the motor 1 and improving the utilization rate of the space in the motor 1, thereby facilitating the miniaturization of the motor 1. Exemplarily, the center of the base 10 and the center of the anti-shake support 21 can be located on the optical axis of the lens 2 (please refer to FIG. 5).

[0169] Exemplarily, the first surface 11a of the bottom plate 11 of the base 10 faces the anti-shake support 21. The first protruding column 112a of the base 10 is opposite to and spaced apart from the first end 2111a of the first edge part 211a. The second protruding column 112b of the base 10 is opposite to and spaced apart from the first end 2111b of the second edge part 211b. The third protruding column 112c of the base 10 is opposite to and spaced apart from the first end 2111c of the third edge part 211c. The fourth protruding column 112d of the base 10 is opposite to and spaced apart from the first end 2111d of the fourth edge part 211d.

[0170] For example, the first anti-shake coil 221a is arranged to face the first anti-shake magnetic element 222a, and is used to drive the anti-shake holder 21 to move relative to the base 10 along a first direction (i.e., the X-axis direction), and the first anti-shake magnetic element 222a and the first anti-shake coil 221a are arranged along a third direction (i.e., the Z-axis direction). Here, the first anti-shake coil 221a is arranged to face the first anti-shake magnetic element 222a means that the winding plane of the first anti-shake coil 221a faces the first anti-shake magnetic element 222a. For example, the winding plane of the first anti-shake coil 221a can be arranged perpendicular to the third direction, and in this case, the first anti-shake coil 221a can be arranged horizontally, which is beneficial to reducing the size of the motor 1 along the third direction, and achieving miniaturization of the motor 1. For example, the first position sensor 223a can be used to detect the first magnetic field variation of the first anti-shake magnetic element 222a when the anti-shake holder 21 moves along the first direction, i.e., to detect the position change of the anti-shake holder 21 along the first direction.

[0171] In addition, by arranging the first anti-shake coil 221a and the first anti-shake magnetic element 222a along the third direction (i.e., the Z-axis direction), during the movement of the anti-shake holder 21 relative to the base 10, the movement direction of the anti-shake holder 21 can be perpendicular to the magnetic gap between the first anti-shake magnetic element 222a and the first anti-shake coil 221a, and the magnetic gap is not affected by the movement of the anti-shake holder 21, so that the problem of rapid decline of driving force caused by increase of the magnetic gap can be avoided, and the stability of the driving force can be ensured while having a large anti-shake driving force, which is beneficial to the design of large-stroke anti-shake.

[0172] In some embodiments, the second anti-shake coil 221b is arranged to face the second anti-shake magnetic element 222b, and is used to drive the anti-shake holder 21 to move relative to the base 10 along a second direction (i.e., the Y-axis direction), and the second anti-shake magnetic element 222b and the second anti-shake coil 221b are arranged along the third direction (i.e., the Z-axis direction). Here, the second anti-shake coil 221b is arranged to face the second anti-shake magnetic element 222b means that the winding plane of the second anti-shake coil 221b faces the second anti-shake magnetic element 222b. For example, the winding plane of the second anti-shake coil 221b can be arranged perpendicular to the third direction, and in this case, the second anti-shake coil 221b can be arranged horizontally, which is beneficial to reducing the size of the motor 1 along the third direction, and achieving miniaturization of the motor 1. For example, the second position sensor 223b (see FIG. 11) can be used to detect the second magnetic field variation of the second anti-shake magnetic element 222b when the anti-shake holder 21 moves along the second direction, i.e., to detect the position change of the anti-shake holder 21 along the second direction.

[0173] In addition, by arranging the second anti-shake coil 221b and the second anti-shake magnetic element 222b in the third direction Z, the movement direction of the anti-shake holder 21 during movement relative to the base 10 can be perpendicular to the magnetic gap of the second anti-shake magnetic element 222b and the second anti-shake coil 221b, which is not affected by the movement of the anti-shake holder 21, thereby avoiding the problem of rapid decline in driving force due to an increase in the magnetic gap, and ensuring the stability of the driving force while having a large anti-shake driving force, which is beneficial to the design of a large stroke anti-shake.

[0174] In some embodiments, the anti-shake holder 21 can be movably connected to the base 10 through the rolling connection between the ball group 23 and the base 10. For example, the anti-shake holder 21 can be movably connected to the base 10 through the first ball group 231, the second ball group 232, and the third ball group 233. In this embodiment, the ball group 23 plays a supporting role, which can reduce the frictional resistance between the balls and the anti-shake holder 21 while ensuring that sufficient supporting force is provided, thereby improving the smoothness of the movement of the anti-shake holder 21 movably connected to the base 10. In addition, the ball group 23 can provide multi-point support for the anti-shake holder 21, which is beneficial to dispersing stress and preventing deformation of the balls when they are subjected to impact due to excessive concentration of stress in a single direction, thereby improving the reliability of the ball group 23 in supporting the anti-shake holder 21 and other structural components. In addition, compared with the diameter of a large ball in the prior art, the smaller diameter of each ball in the ball group 23 of the present embodiment is also beneficial to shortening the distance between the anti-shake holder 21 and the base 10, thereby facilitating the thinning of the motor.

[0175] In other embodiments, the motor 1 can also not include the ball group 23, and the anti-shake holder 21 can be movably connected to the base 10 through other structures, which are not limited in the present application.

[0176] Please refer to FIGS. 17-18B, FIG. 18A is a schematic view of part of the structure of the motor 1 shown in FIG. 6 in some embodiments from another angle, and FIG. 18B is a schematic view of part of the structure of the motor 1 shown in FIG. 6 in some embodiments from another angle.

[0177] In some embodiments, at least part of the groove 2119 of the anti-shake support 21 can be arranged opposite to the rolling groove 114 of the base 10, and part of the balls of the ball group 23 can be located in the groove 2119 of the anti-shake support 21, and part of the balls can be located in the rolling groove 114 of the base 10. For example, part of the balls of the first ball group 231 can be located in the first groove 2119a of the anti-shake support 21, and part of the balls can be located in the first rolling groove 1141 of the base 10, and the balls of the first ball group 231 can be in contact with the first insert 212a of the anti-shake support 21 and the reinforcing portion 125 of the base 10. It can be understood that the first rolling groove 1141 can be arranged opposite to the first end 2111a of the first edge portion 211a. The second rolling groove 1142 can be arranged opposite to the first end 2111b of the second edge portion 211b. The third rolling groove 1143 can be arranged opposite to the first end 2111c of the fourth edge portion 211d.

[0178] In the present embodiment, the first insert 212a of the anti-shake support 21 and the reinforcing portion 125 of the base 10 are both made of steel sheets, and by arranging the first insert 212a of the anti-shake support 21 and the reinforcing portion 125 of the base 10 to contact the corresponding ball group 23, the first insert 212a of the anti-shake support 21 and the reinforcing portion 125 of the base 10 can avoid deformation of the anti-shake support 21 and the base 10 under pressure, and can also reduce the frictional resistance of the ball group 23 during rolling.

[0179] In the present embodiment, the second ball group 232 and the third ball group 23 are arranged in a similar manner to the first ball group 231, and the arrangement of the second ball group 232 and the third ball group 23 can refer to the arrangement of the first ball group 231, which will not be described here.

[0180] In the present embodiment, the first ball group 231 is connected at the connection between the first edge portion 211a and the second edge portion 211b, the second ball group 232 is connected at the connection between the second edge portion 211b and the third edge portion 211c, and the third ball group 233 is connected at the connection between the fourth edge portion 211d and the first edge portion 211a, so that the three ball groups 23 can form a three-point support structure, which can not only ensure the bearing capacity of the ball group 23 on the anti-shake support 21, but also reduce the number of ball groups 23 and the manufacturing cost of the motor 1.

[0181] In some embodiments, the first edge portion 211a of the anti-shake bracket 21 can have a center axis 2110a, and the center axis 2110a of the first edge portion 211a can be parallel to the first direction (i.e., the X-axis direction). Along the second direction (i.e., the Y-axis direction), the center of the first rolling groove 1141 can be located on the first side 2110c of the center axis 2110a of the first edge portion 211a. Among them, the first side 2110c of the center axis 2110a of the first edge portion 211a is close to the center of the anti-shake bracket 21. That is, in the Y-axis direction, the distance between the center position of the first rolling groove 1141 and the center of the anti-shake bracket 21 is less than the distance between the center axis 2110a of the first edge portion 211a and the center of the anti-shake bracket 21.

[0182] It can be understood that the anti-shake bracket 21 will also be affected by the friction torque between the anti-shake bracket 21 and each ball group 23 during movement. Among them, the friction torque is positively correlated with the force arm of each friction force. And the force arm of each friction force is the distance from the center of each ball group 23 to the center of the anti-shake bracket 21. In this embodiment, by setting the center of the rolling groove 114 close to the center of the anti-shake bracket 21, the force arm of the corresponding ball group 23 can be reduced, thereby reducing the influence of the friction torque between the anti-shake bracket 21 and the ball group 23 on the anti-shake bracket 21, and facilitating to improve the response rate of the motor 1 and the anti-shake effect when the anti-shake bracket 21 is movably connected to the base 10 through the ball group 23.

[0183] In some embodiments, the second edge portion 211b of the anti-shake bracket 21 can have a center axis 2110b, and the center axis 2110b of the second edge portion 211b can be parallel to the second direction (i.e., the Y-axis direction). Along the first direction (i.e., the X-axis direction), the center of the second rolling groove 1142 can be located on the first side 2110d of the center axis 2110b of the second edge portion 211b. Among them, the first side 2110d of the center axis 2110b of the second edge portion 211b is close to the center of the anti-shake bracket 21. That is, in the X-axis direction, the distance between the center position of the second rolling groove 1142 and the center of the anti-shake bracket 21 is less than the distance between the center axis 2110b of the second edge portion 211b and the center of the anti-shake bracket 21. In this way, the influence of the friction torque between the anti-shake bracket 21 and the ball group 23 on the anti-shake bracket 21 can be reduced, thereby facilitating to improve the response rate of the motor 1 and the anti-shake effect when the anti-shake bracket 21 is movably connected to the base 10 through the ball group 23.

[0184] In some embodiments, the fourth edge portion 211d of the anti-shake bracket 21 can have a middle axis 2110e, and the middle axis 2110e of the fourth edge portion 211d can be parallel to the first direction (i.e., the X-axis direction). In the second direction (i.e., the Y-axis direction), the center of the third rolling groove 1143 can be located on a first side 2110f of the middle axis 2110e of the fourth edge portion 211d. The first side 2110f of the middle axis 2110e of the fourth edge portion 211d is close to the center of the anti-shake bracket 21. That is, in the Y-axis direction, the distance between the center of the third rolling groove 1143 and the center of the anti-shake bracket 21 is less than the distance between the middle axis 2110e of the fourth edge portion 211d and the center of the anti-shake bracket 21. In this way, the influence of the friction torque between the anti-shake bracket 21 and the ball group 23 on the anti-shake bracket 21 can be reduced, which is conducive to improving the response rate and the anti-shake effect of the motor 1 when the anti-shake bracket 21 is movably connected to the base 10 through the ball group 23.

[0185] Please refer to FIG. 16 and FIG. 19, and FIG. 19 is a structural schematic diagram of the partial structure of the motor 1 in another angle shown in FIG. 16.

[0186] In some embodiments, each reed 30 includes a first fixed end 301, a second fixed end 302, and a connecting segment 303 connected between the first fixed end 301 and the second fixed end 302 and in a bent shape. The first fixed end 301 of the reed 30 is fixedly connected to the anti-shake bracket 21, and the second fixed end 302 of the reed 30 is fixedly connected to the base 10. The reed 30 can be used to provide an elastic force for moving the anti-shake bracket 21 back to the balance position when the anti-shake bracket 21 moves relative to the base 10 and deviates from the balance position. For example, the at least four reeds 30 can include a first reed 31, a second reed 32, a third reed 33, and a fourth reed 34. The first reed 31 and the third reed 33 form a first pair, and the second reed 32 and the fourth reed 34 form a second pair. The two dashed circles in FIG. 19 are enlarged views of the structures of the first reed 31 and the second reed 32, respectively.

[0187] For example, the connecting line of the first reed 31 and the third reed 33 is a first connecting line S1, the connecting line of the second reed 32 and the fourth reed 34 is a second connecting line S2, and the first connecting line S1 intersects the second connecting line S2. It can be understood that the connecting line of the first reed 31 and the third reed 33 can be the connecting line of the geometric center of the first reed 31 and the geometric center of the third reed 33. The connecting line of the second reed 32 and the fourth reed 34 can be the connecting line of the geometric center of the second reed 32 and the geometric center of the fourth reed 34.

[0188] The first spring 31 includes a first fixed end 311, a second fixed end 312, and a first connecting section 313 connected between the first fixed end 311 and the second fixed end 312. The first connecting section 313 can be bent, for example, the first connecting section 313 can be substantially in a wave shape. The first connecting section 313 can include a plurality of first subsections 3131 connected in sequence from the first fixed end 311 to the second fixed end 312. The plurality of first subsections 3131 are schematically divided by the dashed boxes in FIG. 19.

[0189] At least part of the first subsection 3131 can be curved. The curved direction of the first subsection 3131 is perpendicular to the direction from the first fixed end 311 to the second fixed end 312. In some examples, the first subsection 3131 can be in an arc shape, the first subsection 3131 can include two straight sections and an arc section connected between the two straight sections, the extension direction of the straight sections is perpendicular to the direction from the first fixed end 311 to the second fixed end 312, and the inner normal direction of the arc section is perpendicular to the direction from the first fixed end 311 to the second fixed end 312. Alternatively, the first subsection 3131 can be an arc section, and the inner normal direction of the first subsection 3131 is perpendicular to the direction from the first fixed end 311 to the second fixed end 312. It can be understood that the shapes and sizes of the plurality of first subsections 3131 can be different, and the shapes and sizes of the plurality of first subsections 3131 do not need to be completely the same.

[0190] The first fixed end 311 of the first spring 31 can be fixedly connected to the first protrusion 2113a of the anti-shake support 21, so that the first fixed end 311 can be fixed to the first end 2111a of the first side portion 211a. In some examples, at least part of the first fixed end 311 can be located in the fixing groove 2114a of the first protrusion 2113a. The second fixed end 312 of the first spring 31 is fixedly connected to the first protruding column 112a of the base 10. In this embodiment, the first spring 31 can be used to provide an elastic force to move the anti-shake support 21 back to the balance position when the anti-shake support 21 moves relative to the base 10 and deviates from the balance position. In addition, the first spring 31 can be located at one corner of the anti-shake support 21, the first spring 31 does not occupy too much space on the first side portion 211a, which is beneficial to reasonably utilize the space on the first side portion 211a, the position of the first spring 31 is reasonably arranged, which is beneficial to improve the space utilization rate of the motor 1.

[0191] For example, the first spring 31 can be arranged in the X-Y plane. The first spring 31 can be arranged on the side of the anti-shake holder 21 away from the bottom plate 11 of the base 10. In the Z-axis direction, a portion of the first connecting segment 313 of the first spring 31 can be arranged opposite and spaced apart from the first end 2111a of the first side portion 211a. In FIG. 19, the first side portion 211a, the second side portion 211b, the third side portion 211c, and the fourth side portion 211d are schematically divided by dashed lines. In this embodiment, when the anti-shake holder 21 moves relative to the base 10 in the X-Y plane, the first spring 31 can provide an elastic force that moves the anti-shake holder 21 back to the equilibrium position, and can limit the displacement of the anti-shake holder 21 in the Z-axis direction to a certain extent. In addition, by arranging the first protrusion 2113a and the first protruding column 112a, the first spring 31 can be arranged above the first end 2111a of the first side portion 211a, so that the first spring 31 can be arranged using the space above the first side portion 211a of the anti-shake holder 21, so that the structure of the motor 1 is more compact.

[0192] For example, the first fixed end 311 of the first spring 31 can be parallel to the first direction (i.e., the X-axis direction) in the direction of the second fixed end 312 of the first spring 31, i.e., the arrangement direction of the first spring 31 is parallel to the first direction. It can be understood that the arrangement direction of the first spring 31 is the direction in which the first fixed end 311 of the first spring 31 points to the second fixed end 312. At this time, the plurality of first segments 3131 in the first connecting segment 313 can be arranged along the first direction. At least part of the first segment 3131 can be curved towards the third side portion 211c. For example, the first segment 3131 can be arc-shaped, the first segment 3131 can include two straight segments and an arc segment, the arc segment can be connected between the two straight segments, the extension direction of the straight segment can be parallel to the second direction, and the inner normal direction of the arc segment can be parallel to the second direction; or the first segment 3131 can be an arc segment, and the inner normal direction of the first segment 3131 can be parallel to the second direction. It can be understood that in some other examples, the first segment 3131 can also be curved away from the third side portion 211c.

[0193] In this embodiment, the first segment 3131 is prone to deformation in the first direction due to being squeezed or stretched, so that the deformation ability of the first connecting segment 313 in the first direction is better than that in other directions (e.g., the second direction). When the anti-shake holder 21 moves relative to the base 10 in the first direction, the first spring 31 can be deformed in the first direction.

[0194] In some examples, the first spring 31 can be made of copper alloy, steel, or the like. In this way, the first spring 31 can have a large stiffness. The first spring 31 can provide a large force to move the anti-shake support 21 back to the equilibrium position.

[0195] Referring to FIGS. 16 and 19, the second spring 32 includes a first fixed end 321, a second fixed end 322, and a second connecting segment 323 connected between the first fixed end 321 and the second fixed end 322. In an example, the second connecting segment 323 can be bent, for example, the second connecting segment 323 can be substantially wavy. The second connecting segment 323 can include a plurality of second segments 3231 connected in sequence in a direction from the first fixed end 321 to the second fixed end 322. In FIG. 19, the plurality of second segments 3231 are schematically divided by dashed boxes.

[0196] In an example, at least part of the second segment 3231 can be bent. The bending direction of the second segment 3231 intersects the direction from the first fixed end 321 to the second fixed end 322, for example, the bending direction of the second segment 3231 can be perpendicular to the direction from the first fixed end 321 to the second fixed end 322. The structure of the second segment 3231 and the second connecting segment 323 is similar to that of the first segment 3131 and the first connecting segment 313, and the structure of the second segment 3231 and the second connecting segment 323 can refer to the structure of the first segment 3131 and the first connecting segment 313, which will not be described here.

[0197] In an example, the first fixed end 321 of the second spring 32 can be fixedly connected to the second protrusion 2113b of the anti-shake support 21, so that the first fixed end 321 can be fixed to the first end 2111b of the second side portion 211b. The second fixed end 322 of the second spring 32 can be fixedly connected to the second protrusion 112b of the base 10. In this embodiment, the second spring 32 can be used to provide an elastic force to move the anti-shake support 21 back to the equilibrium position when the anti-shake support 21 moves relative to the base 10 and deviates from the equilibrium position, and can limit the displacement of the anti-shake support 21 in the Z-axis direction to a certain extent. In addition, the second spring 32 can be located at one corner of the anti-shake support 21, and the second spring 32 does not occupy too much space on the second side portion 211b, which is conducive to reasonably utilizing the space on the second side portion 211b, and the position of the second spring 32 is reasonably arranged, which is conducive to improving the space utilization of the motor 1.

[0198] In some examples, the second spring 32 can be arranged on a side of the anti-vibration bracket 21 opposite to the base 10. In the Z-axis direction, a portion of the second connecting segment 323 of the second spring 32 can be arranged opposite to and spaced apart from the first end 2111b of the second side portion 211b. When the anti-vibration bracket 21 moves relative to the base 10 in the X-Y plane, the second spring 32 can provide an elastic force to move the anti-vibration bracket 21 back to the equilibrium position. In addition, by arranging the second protrusion 2113b and the second protruding column 112b, the second spring 32 can be arranged above the first end 2111b of the second side portion 211b, so that the second spring 32 can be arranged using the space above the second side portion 211b of the anti-vibration bracket 21, so that the structure of the motor 1 is more compact.

[0199] In some examples, the first fixed end 321 of the second spring 32 can be parallel to the second direction (i.e., the Y-axis direction) in the direction of the second fixed end 322 of the second spring 32, i.e., the arrangement direction of the second spring 32 is parallel to the first direction. It can be understood that the arrangement direction of the second spring 32 is the direction of the first fixed end 321 of the second spring 32 pointing to the second fixed end 322. At this time, the plurality of second segments 3231 in the second connecting segment 323 can be arranged along the second direction. At least part of the second segment 3231 can be bent towards the fourth side portion 211d. It can be understood that in some other examples, the second segment 3231 can also be bent away from the fourth side portion 211d.

[0200] In the present embodiment, the second segment 3231 is prone to deformation in the second direction due to being pressed or stretched, so that the deformation ability of the second connecting segment 323 in the second direction is better than the deformation ability in other directions (e.g., the first direction). When the anti-vibration bracket 21 moves relative to the base 10 in the second direction, the second spring 32 can be deformed in the second direction.

[0201] In some examples, the material of the second spring 32 can be copper alloy, steel, etc. In this way, the second spring 32 can have greater rigidity. The second spring 32 can provide greater force to move the anti-vibration bracket 21 back to the equilibrium position.

[0202] In some examples, the third spring 33 includes a first fixed end 331, a second fixed end 332, and a third connecting segment 333 connected between the first fixed end 331 and the second fixed end 332. In some examples, the third connecting segment 333 can be bent, e.g., the third connecting segment 333 can be substantially wave-shaped. The third connecting segment 333 can include a plurality of third segments 3331 connected in sequence in the direction of the first fixed end 331 to the second fixed end 332.

[0203] Exemplarily, at least part of the third segment 3331 can be bent. The bending direction of the third segment 3331 is intersected with the direction from the first fixed end 331 to the second fixed end 332, for example, the bending direction of the third segment 3331 can be perpendicular to the direction from the first fixed end 331 to the second fixed end 332. The structural arrangement of the third segment 3331 and the third connecting segment 333 is similar to the structural arrangement of the first segment 3131 and the first connecting segment 313, and the structural arrangement of the third segment 3331 and the third connecting segment 333 can refer to the structural arrangement of the first segment 3131 and the first connecting segment 313, which will not be repeated here.

[0204] Exemplarily, the first fixed end 331 of the third spring piece 33 can be fixedly connected with the third protrusion 2113c of the anti-shake support 21, so that the first fixed end 331 can be fixed to the first end 2111c of the third side portion 211c. The second fixed end 332 of the third spring piece 33 can be fixedly connected with the third protruding column 112c of the base 10. In the embodiment, the third spring piece 33 can be used to provide an elastic force for moving the anti-shake support 21 back to the balance position when the anti-shake support 21 moves relative to the base 10 and deviates from the balance position, and can limit the displacement of the anti-shake support 21 in the Z-axis direction to a certain extent. In addition, the third spring piece 33 can be located at one corner of the anti-shake support 21, the third spring piece 33 does not occupy too much space on the third side portion 211c, which is conducive to reasonably utilizing the space on the third side portion 211c, and the position arrangement of the third spring piece 33 is more reasonable, which is conducive to improving the space utilization rate of the motor 1.

[0205] Exemplarily, the plane where the third spring piece 33 is located can be perpendicular to the third direction, that is, the third spring piece 33 can be arranged in the X-Y plane. The third spring piece 33 can be located on the side of the anti-shake support 21 away from the bottom plate 11 of the base 10. In the Z-axis direction, part of the third connecting segment 333 of the third spring piece 33 can be oppositely and spacedly arranged relative to the first end 2111c of the third side portion 211c. When the anti-shake support 21 moves relative to the base 10 in the X-Y plane, the third spring piece 33 can provide an elastic force for moving the anti-shake support 21 back to the balance position. In addition, by arranging the third protrusion 2113c and the third protruding column 112c, the third spring piece 33 can be located above the first end 2111c of the third side portion 211c, and the third spring piece 33 can be arranged by using the space above the third side portion 211c of the anti-shake support 21, so that the structure of the motor 1 is more compact.

[0206] For example, the first fixed end 331 of the third spring piece 33 can be parallel to the first direction (i.e., the X-axis direction) in the direction of the second fixed end 332 of the third spring piece 33, i.e., the arrangement direction of the third spring piece 33 is parallel to the first direction. It can be understood that the arrangement direction of the third spring piece 33 is the direction of the first fixed end 331 pointing to the second fixed end 332. At this time, the plurality of third segments 3331 in the third connecting segment 333 can be arranged along the first direction. At least part of the third segment 3331 can be bent towards the first edge portion 211a. It can be understood that in other examples, the third segment 3331 can also be bent away from the first edge portion 211a. It can be understood that in the embodiment of the present application, the direction of the first fixed end 331 of the third spring piece 33 to the second fixed end 332 can be parallel to the direction of the first fixed end 311 of the first spring piece 31 to the second fixed end 312.

[0207] In the embodiment, the third segment 3331 is easy to deform in the first direction due to being squeezed or stretched, so that the deformation ability of the third connecting segment 333 in the first direction is better than that in other directions (for example, the second direction). When the anti-shake support 21 moves relative to the base 10 along the first direction, the third spring piece 33 can deform along the first direction.

[0208] In some examples, the material of the third spring piece 33 can be copper alloy, steel, etc. In this way, the third spring piece 33 can have greater rigidity. The third spring piece 33 can provide greater force to move the anti-shake support 21 back to the equilibrium position.

[0209] In some embodiments, the fourth spring piece 34 includes a first fixed end 341, a second fixed end 342, and a fourth connecting segment 343 connected between the first fixed end 341 and the second fixed end 342. For example, the fourth connecting segment 343 can be bent, for example, the fourth connecting segment 343 can be substantially wave-shaped. The fourth connecting segment 343 can include a plurality of fourth segments 3431, which are sequentially connected in the direction of the first fixed end 341 to the second fixed end 342.

[0210] For example, at least part of the fourth segment 3431 can be bent. The bending direction of the fourth segment 3431 intersects the direction of the first fixed end 341 to the second fixed end 342, for example, the bending direction of the fourth segment 3431 can be perpendicular to the direction of the first fixed end 341 to the second fixed end 342. The structure of the fourth segment 3431 and the fourth connecting segment 343 is similar to that of the first segment 3131 and the first connecting segment 313, and the structure of the fourth segment 3431 and the fourth connecting segment 343 can be referred to the structure of the first segment 3131 and the first connecting segment 313, which will not be described here.

[0211] Exemplarily, the first fixed end 341 of the fourth spring piece 34 can be fixedly connected with the fourth protrusion 2113d of the anti-shake support 21, so that the first fixed end 341 can be fixed to the first end 2111d of the fourth side portion 211d. The second fixed end 342 of the fourth spring piece 34 can be fixedly connected with the fourth protruding column 112d of the base 10. In the embodiment, the fourth spring piece 34 can be used to provide an elastic force for moving the anti-shake support 21 back to the balance position when the anti-shake support 21 moves relative to the base 10 and deviates from the balance position, and can limit the displacement of the anti-shake support 21 in the Z-axis direction to a certain extent. In addition, the fourth spring piece 34 can be located at one corner of the anti-shake support 21, the fourth spring piece 34 does not occupy too much space on the fourth side portion 211d, which is conducive to reasonably utilizing the space on the fourth side portion 211d, the position of the fourth spring piece 34 is more reasonable, and the space utilization rate of the motor 1 is improved.

[0212] Exemplarily, the plane where the fourth spring piece 34 is located can be perpendicular to the third direction, that is, the fourth spring piece 34 can be arranged in the X-Y plane. The fourth spring piece 34 can be located on the side of the anti-shake support 21 away from the bottom plate 11 of the base 10. In the Z-axis direction, part of the fourth connecting segment 343 of the fourth spring piece 34 can be oppositely and spacedly arranged relative to the first end 2111d of the fourth side portion 211d. When the anti-shake support 21 moves relative to the base 10 in the X-Y plane, the fourth spring piece 34 can provide an elastic force for moving the anti-shake support 21 back to the balance position. In addition, by arranging the fourth protrusion 2113d and the fourth protruding column 112d, the fourth spring piece 34 can be located above the first end 2111d of the fourth side portion 211d, and the fourth spring piece 34 can be arranged by using the space above the fourth side portion 211d of the anti-shake support 21, so that the structure of the motor 1 is more compact.

[0213] Exemplarily, the direction from the first fixed end 341 of the fourth spring piece 34 to the second fixed end 342 of the fourth spring piece 34 can be parallel to the second direction (that is, the Y-axis direction), that is, the arrangement direction of the fourth spring piece 34 is parallel to the first direction. It can be understood that the arrangement direction of the fourth spring piece 34 is the direction from the first fixed end 341 of the fourth spring piece 34 to the second fixed end 342. At this time, the plurality of fourth segments 3431 in the fourth connecting segment 343 can be arranged in the fourth direction. At least part of the fourth segments 3431 can be bent towards the second side portion 211b. It can be understood that in some other examples, the fourth segments 3431 can also be bent away from the second side portion 211b. It can be understood that in the embodiment, the direction from the first fixed end 341 of the fourth spring piece 34 to the second fixed end 342 can be parallel to the direction from the first fixed end 321 of the second spring piece 32 to the second fixed end 322 of the second spring piece 32.

[0214] In the embodiment, the fourth segment 3431 is easy to be deformed by being compressed or stretched in the second direction, so that the fourth connecting segment 343 has better deformation capability in the second direction than in other directions (e.g., the first direction). When the anti-shake support 21 moves relative to the base 10 in the second direction, the fourth spring sheet 34 can be deformed in the second direction.

[0215] In some examples, the material of the fourth spring sheet 34 can be a copper alloy, steel, or the like. In this way, the fourth spring sheet 34 can have greater rigidity. The fourth spring sheet 34 can provide greater force to move the anti-shake support 21 back to the equilibrium position.

[0216] In the embodiment, one fixed end of each of the first spring sheet 31, the second spring sheet 32, the third spring sheet 33, and the fourth spring sheet 34 is fixed to a corresponding corner of the anti-shake support 21, and the other fixed end of each of the first spring sheet 31, the second spring sheet 32, the third spring sheet 33, and the fourth spring sheet 34 is connected to a corresponding position of the base 10. The arrangement direction of the first spring sheet 31 and the third spring sheet 33 is parallel to the first direction, and the arrangement direction of the second spring sheet 32 and the fourth spring sheet 34 is parallel to the second direction. When the anti-shake support 21 moves relative to the base 10 in the first direction, the first spring sheet 31 and the third spring sheet 33 can be deformed in the first direction, and the first spring sheet 31 and the third spring sheet 33 can provide elastic force in the first direction to the anti-shake support 21, so that the anti-shake support 21 can return to the equilibrium position. The second spring sheet 32 and the fourth spring sheet 34 can provide force in the second direction to the anti-shake support 21, and the direction of the force provided by the second spring sheet 32 to the anti-shake support 21 is opposite to the direction of the force provided by the fourth spring sheet 34 to the anti-shake support 21, and the resultant force can be zero (or close to zero), so that the second spring sheet 32 and the fourth spring sheet 34 can limit the displacement of the anti-shake support 21 in the second direction, so that the anti-shake support 21 can be displaced relative to the base 10 in the first direction, and the anti-shake support 21 is not easy to deviate, that is, accurate guidance can be achieved during the movement of the anti-shake support 21 relative to the base 10 in the first direction, which is beneficial to improve the reliability and control accuracy of the motor 1, and further beneficial to achieve large-stroke anti-shake design of the camera module 100.

[0217] When the anti-shake support 21 moves relative to the base 10 along the second direction, the second spring piece 32 and the fourth spring piece 34 can be deformed along the second direction, and the second spring piece 32 and the fourth spring piece 34 can provide the anti-shake support 21 with an elastic force along the first direction, so that the anti-shake support 21 can return to the balance position; the first spring piece 31 and the third spring piece 33 can provide the anti-shake support 21 with a force along the first direction, and the direction of the force provided by the first spring piece 31 to the anti-shake support 21 is opposite to the direction of the force provided by the third spring piece 33 to the anti-shake support 21, and the resultant force can be zero (or close to zero), so that the first spring piece 31 and the third spring piece 33 can limit the displacement of the anti-shake support 21 in the first direction, so that the anti-shake support 21 can be displaced relative to the base 10 along the second direction, and the anti-shake support 21 is not easy to deviate, that is, accurate guidance can be achieved during the movement of the anti-shake support 21 relative to the base 10 along the second direction, which is beneficial to improve the reliability and control accuracy of the motor 1, and thus is beneficial to realize the large-stroke anti-shake design of the camera module 100. In the embodiment of the present application, the camera module 100 has better imaging quality and control accuracy, which is beneficial to improve the shooting performance of the electronic device 1000.

[0218] In the embodiment of the present application, the motor 1 can guide the anti-shake support 21 in the first direction (i.e., the X-axis direction) and the second direction (i.e., the Y-axis direction) through the cooperation of the first spring piece 31, the second spring piece 32, the third spring piece 33 and the fourth spring piece 34, and the guidance in the two directions is not easy to interfere, thereby being beneficial to realize accurate guidance of optical anti-shake. Among them, based on the guidance of the first spring piece 31 and the third spring piece 33, the anti-shake support 21 can move relative to the base 10 along the first direction, and based on the guidance of the second spring piece 32 and the fourth spring piece 34, the anti-shake support 21 can move relative to the base 10 along the second direction, so that the motor 1 can realize accurate guidance in the optical anti-shake process through the cooperation of the base 10, the first spring piece 31, the second spring piece 32, the third spring piece 33, the fourth spring piece 34 and the anti-shake support 21, thereby solving the problem of excessive lens tilt in the optical anti-shake process of the traditional motor 1. It can be understood that in the embodiment of the present application, the center of gravity, the geometric center of the motor 1 coincide with the mechanical center between the X-axis direction and the Y-axis direction, and are located on the optical axis.

[0219] In the embodiments of the present application, the stiffness of the first reed 31, the second reed 32, the third reed 33 and the fourth reed 34 can be set to be relatively large. For example, the first reed 31, the second reed 32, the third reed 33 and the fourth reed 34 can use some metal materials with relatively large stiffness, so that when the first reed 31, the second reed 32, the third reed 33 and the fourth reed 34 cooperate with each other to guide the anti-shake support 21 in the first direction (i.e., the X-axis direction) and the second direction (i.e., the Y-axis direction), the risk of crosstalk of the guidance in the two directions can be reduced, so that the guidance in the two directions is not prone to crosstalk, thereby facilitating accurate guidance of optical anti-shake, improving the reliability and control accuracy of the motor 1, and further facilitating the design of large-stroke anti-shake of the camera module 100.

[0220] It can be understood that, in the process of movement of the anti-shake support 21 relative to the base 10 in the first direction and in the second direction, if the anti-shake support 21 is subjected to a non-zero moment, the anti-shake support 21 will be offset. In some embodiments, the first reed 31 and the third reed 33 are centrally symmetrically distributed relative to the center of the anti-shake support 21. In this way, when the anti-shake support 21 moves relative to the base 10 in the second direction and is guided by the first reed 31 and the third reed 33, the resultant moment of the first reed 31 and the third reed 33 on the anti-shake support 21 can be zero (or close to zero), so that displacement of the anti-shake support 21 relative to the base 10 in a direction other than the second direction can be avoided, thereby achieving more accurate guidance during movement of the anti-shake support 21 relative to the base 10 in the second direction, and facilitating improvement of the reliability and control accuracy of the motor 1, and further facilitating the design of large-stroke anti-shake of the camera module 100.

[0221] It can be understood that the central symmetric distribution of the first reed 31 and the third reed 33 relative to the center of the anti-shake support 21 means that the positions and structures of the first reed 31 and the third reed 33 can be centrally symmetrically distributed relative to the center of the anti-shake support 21, or the positions of the first reed 31 and the third reed 33 can be centrally symmetrically distributed relative to the center of the anti-shake support 21, and the structures of the first reed 31 and the third reed 33 can not be centrally symmetrically distributed relative to the center of the anti-shake support 21. The embodiments of the present application are described by taking the positions and structures of the first reed 31 and the third reed 33 as examples which are centrally symmetrically distributed relative to the center of the anti-shake support 21.

[0222] In some embodiments, the second spring 32 and the fourth spring 34 are centrally symmetrically distributed relative to the center of the anti-shake bracket 21. In this way, when the anti-shake bracket 21 moves relative to the base 10 in the first direction, the second spring 32 and the fourth spring 34 guide the anti-shake bracket 21 by cooperating with each other, the resultant moment of the second spring 32 and the fourth spring 34 on the anti-shake bracket 21 can be zero (or close to zero), so as to avoid displacement of the anti-shake bracket 21 relative to the base 10 in a direction other than the first direction, so as to achieve more accurate guidance during movement of the anti-shake bracket 21 relative to the base 10 in the first direction, and facilitate improvement of the reliability and control accuracy of the motor 1, and further facilitate implementation of the large-stroke anti-shake design of the camera module 100.

[0223] It can be understood that the central symmetric distribution of the second spring 32 and the fourth spring 34 relative to the center of the anti-shake bracket 21 means that the positions and structures of the second spring 32 and the fourth spring 34 can be centrally symmetrically distributed relative to the center of the anti-shake bracket 21, or the positions of the second spring 32 and the fourth spring 34 can be centrally symmetrically distributed relative to the center of the anti-shake bracket 21, and the structures of the second spring 32 and the fourth spring 34 can not be centrally symmetrically distributed relative to the center of the anti-shake bracket 21. The embodiments of the present application are described by taking the positions and structures of the second spring 32 and the fourth spring 34 as examples which are centrally symmetrically distributed relative to the center of the anti-shake bracket 21.

[0224] In the embodiments of the present application, by setting the first spring 31 and the third spring 33 to be centrally symmetrically distributed relative to the center of the anti-shake bracket 21, and the second spring 32 and the fourth spring 34 to be centrally symmetrically distributed relative to the center of the anti-shake bracket 21, the risk of crosstalk of the guidance in two directions can be further reduced, so as to facilitate accurate guidance of optical anti-shake, improve the reliability and control accuracy of the motor 1, and further facilitate implementation of the large-stroke anti-shake design of the camera module 100.

[0225] In the embodiments of the present application, the first reed 31 is arranged corresponding to the first end 2111a of the first side portion 211a, the second reed 32 is arranged corresponding to the first end 2111b of the second side portion 211b, the third reed 33 is arranged corresponding to the first end 2111c of the third side portion 211c, and the fourth reed 34 is arranged corresponding to the first end 2111d of the fourth side portion 211d. It can be understood that the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34 can be fixed one by one at the four corner portions of the anti-shake bracket 21, so as to on the one hand increase the distance between the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34, and on the other hand facilitate the symmetrical design between the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34, and facilitate the assembly error tolerance of the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34, and facilitate the assembly of the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34.

[0226] In some embodiments, at least one of the first reed 31, the second reed 32, the third reed 33, and the fourth reed 34 can also be made of a conductive material to take into account the signal transmission function.

[0227] Please refer to FIG. 20 and FIG. 21, FIG. 20 is a structural schematic diagram of the partial structure of the motor 1 shown in FIG. 16 from another angle, and FIG. 21 is a partial cross-sectional schematic diagram of the partial structure of the motor 1 shown in FIG. 20 along E-E.

[0228] In some embodiments, the motor 1 can further include an anti-shake magnetic attraction piece 60 fixed to the second surface 11b of the bottom plate 11 of the base 10. For example, the number of the anti-shake magnetic attraction pieces 60 can be two groups, and the two groups of anti-shake magnetic attraction pieces 60 can include a first anti-shake magnetic attraction piece 61 and a second anti-shake magnetic attraction piece 62. The first anti-shake magnetic attraction piece 61 is located in the first side region 111a and is arranged to face the first anti-shake magnetic piece 222a to generate a magnetic attraction force with the first anti-shake magnetic piece 222a, so that the anti-shake bracket 21 has a tendency to be close to the base 10, thereby ensuring that the base 10, the ball group 23, and the anti-shake bracket 21 remain in contact, achieving pre-tightening, and improving the reliability of the optical anti-shake process of the motor. It can be understood that in the Z-axis direction, the first anti-shake magnetic attraction piece 61 at least partially overlaps the first anti-shake magnetic piece 222a.

[0229] Exemplarily, the number of the first anti-shake magnetic attraction members 61 can be one or more. When the number of the first anti-shake magnetic attraction members 61 is one, the first anti-shake magnetic attraction member 61 can be located in the middle of the first edge area 111a. When the number of the first anti-shake magnetic attraction members 61 is more than one, the first anti-shake magnetic attraction members 61 can be arranged at intervals in the first edge area 111a. For example, when the number of the first anti-shake magnetic attraction members 61 is two, the two first anti-shake magnetic attraction members 61 can be arranged at the two ends of the first anti-shake magnetic member 222a.

[0230] The second anti-shake magnetic attraction member 62 can be fixed to the second edge area 111b and arranged to face the second anti-shake magnetic member 222b to generate a magnetic attraction force with the second anti-shake magnetic member 222b, so that the anti-shake bracket 21 has a tendency to be close to the base 10, thereby ensuring that the base 10, the ball group 23 and the anti-shake bracket 21 remain in contact, achieving pre-tightening and improving the reliability of the optical anti-shake process of the motor. It can be understood that, in the Z-axis direction, the second anti-shake magnetic attraction member 62 at least partially overlaps the second anti-shake magnetic member 222b.

[0231] Exemplarily, the number of the second anti-shake magnetic attraction members 62 can be one or more. When the number of the second anti-shake magnetic attraction members 62 is one, the second anti-shake magnetic attraction member 62 can be located in the middle of the second edge area 111b. When the number of the second anti-shake magnetic attraction members 62 is more than one, the second anti-shake magnetic attraction members 62 can be arranged at intervals in the second edge area 111b. For example, when the number of the second anti-shake magnetic attraction members 62 is two, the two second anti-shake magnetic attraction members 62 can be arranged at the two ends of the second anti-shake magnetic member 222b.

[0232] In some examples, the anti-shake magnetic attraction member 60 can be made of a material capable of generating a magnetic attraction force with a magnet or other magnetic component, such as a ferromagnetic material such as steel. The size, shape, etc. of the first anti-shake magnetic attraction member 61 and the second anti-shake magnetic attraction member 62 can be the same or different, which is not limited in the present application. In other embodiments, the motor 1 can not include the first anti-shake magnetic attraction member 61, or the motor 1 can not include the second anti-shake magnetic attraction member 62.

[0233] Please refer to FIG. 22 and FIG. 23, FIG. 22 is a partial structure exploded schematic diagram of the motor 1 shown in FIG. 6 in some embodiments, and FIG. 23 is a partial structure schematic diagram of the motor 1 shown in FIG. 6 in some embodiments. Exemplarily, FIG. 22 mainly shows the structure schematic diagram of the anti-shake bracket 21, the circuit board assembly 43, the focusing coil 421 and the guide rod 44, and FIG. 23 mainly shows the assembly structure schematic diagram of the anti-shake bracket 21, the circuit board assembly 43, the focusing coil 421 and the guide rod 44.

[0234] In some embodiments, the focusing driving chip 432 and the focusing sensor 433 of the circuit board assembly 43 are both fixed on the focusing circuit board 431 and electrically connected to the focusing circuit board 431. The focusing coil 421 is fixed on the focusing circuit board 431 and electrically connected to the focusing circuit board 431. It can be understood that the input end and the output end of the focusing coil 421 can form a current loop with the focusing driving chip 432 through the focusing circuit board 431. At this time, the focusing driving chip 432 can control the current condition (for example, whether to pass current or the size of the current when passing current, etc.) of the focusing coil 421 through the focusing circuit board 431.

[0235] For example, the focusing coil 421 can be arranged around the focusing driving chip 432 and the focusing sensor 433. In this way, the focusing driving chip 432 and the focusing sensor 433 can effectively utilize the inner space of the focusing coil 421, thereby greatly improving the space utilization rate of the motor 1. For example, the focusing sensor 433 is used to realize position detection, and the focusing sensor 433 can adopt a hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0236] In some embodiments, the circuit board assembly 43 can be installed in the third accommodating groove 2117 of the anti-shake bracket 21 to be fixed to the anti-shake bracket 21. For example, the focusing circuit board 431 of the circuit board assembly 43 can be fixed in the third accommodating groove 2117 by means of adhesive or the like. At this time, the focusing coil 421 can be fixed to the anti-shake bracket 21 through the focusing circuit board 431. It can be understood that at least part of the circuit board assembly 43 and at least part of the focusing coil 421 can be located in the third accommodating groove 2117, so that the structural arrangement of the circuit board assembly 43 and the anti-shake bracket 21 is compact, which is beneficial to improve the space utilization rate.

[0237] In the present embodiment, the focusing coil 421 can be fixed to the fourth edge portion 211d of the anti-shake bracket 21, and at this time the focusing coil 421 can be arranged in a spaced manner with the first anti-shake magnetic member 222a and the second anti-shake magnetic member 222b, and the focusing coil 421 will not interfere with the first anti-shake magnetic member 222a and the second anti-shake magnetic member 222b.

[0238] In some embodiments, the guide rods 44 are fixedly connected to the anti-shake support 21, and parts of the guide rods 44 can be located in the fixing grooves 2118 of the anti-shake support 21. For example, the number of the guide rods 44 can be two, and the two guide rods 44 can include a first guide rod 441 and a second guide rod 442. A part of the first guide rod 441 can be located in a first fixing groove 2118a of the anti-shake support 21, and the bottom of the first guide rod 441 can be fixedly connected to the groove wall of the first fixing groove 2118a by welding or the like. A part of the second guide rod 442 can be located in a second fixing groove 2118b, and the bottom of the second guide rod 442 can be fixedly connected to the groove wall of the second fixing groove 2118b by welding or the like. For example, the shapes, sizes, materials, and the like of the two guide rods 44 can be the same or different, and in the embodiments of the present application, the length of the first guide rod 441 in the third direction Z can be greater than the length of the second guide rod 442.

[0239] Referring to FIG. 24, FIG. 24 is a structural exploded view of the focusing support 41 shown in FIG. 6 from another angle.

[0240] In some embodiments, the focusing support 41 can be generally frame-shaped, and the focusing support 41 has a third through hole 411. The focusing support 41 is provided with a fourth accommodating groove 412 and a sliding groove 413. The openings of the fourth accommodating groove 412 and the sliding groove 413 can be arranged away from the third through hole 411. It can be understood that the third through hole 411 of the focusing support 41 is used to mount the lens 2 (see FIG. 5). For example, the central axis of the focusing support 41 is parallel to the optical axis of the lens 2.

[0241] For example, the number of the sliding grooves 413 can be two, and the two sliding grooves 413 can include a first sliding groove 4131 and a second sliding groove 4132. The first sliding groove 4131 and the second sliding groove 4132 can be located on the two sides of the fourth accommodating groove 412. The extension directions of the first sliding groove 4131 and the second sliding groove 4132 can be parallel to the third direction. For example, among the first sliding groove 4131 and the second sliding groove 4132 of the focusing support 41, at least one “V”-shaped groove and at least one “U”-shaped groove or “L”-shaped groove are included. For example, the first sliding groove 4131 can be a “V”-shaped groove, and the first sliding groove 4131 can include a first groove wall 4133 and a second groove wall 4134, which are arranged at an angle. For example, the second sliding groove 4132 can be a “U”-shaped groove or a “L”-shaped groove, and the second sliding groove 4132 can include a third groove wall 4135, which is arranged at an angle with the planes of the first groove wall 4133 of the first sliding groove 4131 and the second groove wall 4134 of the first sliding groove 4131. In some examples, the plane of the third groove wall 4135 of the second sliding groove 4132 can be perpendicular to the X-axis direction.

[0242] Please refer to FIG. 24 and FIG. 25, FIG. 25 is a schematic diagram of the assembly structure between the focusing bracket 41 and the focusing magnetic piece 422 in some embodiments of the motor 1 shown in FIG. 6.

[0243] In some embodiments, the focusing magnetic piece 422 (please refer to FIG. 22) can be installed in the fourth accommodating groove 412 of the focusing bracket 41 to be fixed to the focusing bracket 41.

[0244] For example, the focusing magnetic piece 422 can adopt a double-magnet scheme, for example, composed of two magnets arranged in the first direction and having opposite polar directions. In other embodiments, the focusing magnetic piece 422 is a Halbach magnet array. In other embodiments, the focusing magnetic piece 422 can adopt a single-magnet scheme, for example, composed of one magnet including two parts with opposite polar directions. The magnet can be made by a double-pole magnetization process. In the embodiments of the present application, the focusing magnetic piece 422 is taken as an example of the double-magnet scheme, and the present application is not limited thereto.

[0245] As shown in FIG. 24 and FIG. 25, in some embodiments, the focusing bracket 41 can include a focusing bracket body 41a and a focusing magnetic conducting piece 41b fixed between the focusing bracket body 41a and the focusing magnetic piece 422 for enhancing the magnetic field directivity of the focusing magnetic piece 422. For example, the focusing magnetic conducting piece 41b can be integrally formed with the focusing bracket body 41a by insert-molding or the like. At this time, the focusing magnetic conducting piece 41b is embedded in the focusing bracket 41. In other embodiments, the focusing magnetic conducting piece 41b is mainly distributed between the focusing magnetic piece 422 and the bottom wall of the fourth accommodating groove 412. The focusing magnetic conducting piece 41b can be fixed to the focusing bracket body 41a by adhesion or the like, and the focusing magnetic piece 422 can be fixed to the focusing magnetic conducting piece 41b by adhesion or the like.

[0246] Please refer to FIG. 26 and FIG. 27, FIG. 26 is a schematic diagram of the assembly structure between the focusing bracket 41 and the focusing magnetic piece 422 in some embodiments of the motor 1 shown in FIG. 6, and FIG. 27 is a schematic diagram of the partial cross-sectional structure of the motor 1 along F-F shown in FIG. 26.

[0247] In some embodiments, the focusing holder 41 is mounted on the inner side of the anti-shake holder 21, the third through hole 411 and the second through hole 2115 at least partially overlap, in other words, the focusing holder 41 and the anti-shake holder 21 can also be considered coaxially nested, which is conducive to improving the compactness of the structure in the motor 1 and the utilization rate of the space in the motor 1, and is conducive to realizing the miniaturization of the motor 1.

[0248] For example, the focusing coil 421 faces the focusing magnetic member 422 and is configured to drive the focusing holder 41 to move along the third direction (i.e., the Z-axis direction) relative to the anti-shake holder 21. When the focusing holder 41 moves along the third direction relative to the anti-shake holder 21, the focusing holder 41 can drive the lens 2 mounted thereon to move along the third direction (see FIG. 5), and at this time, the motor 1 can realize the focusing function. For example, the focusing sensor 433 fixed to the focusing circuit board 431 can be configured to detect the position change of the focusing holder 41 along the third direction.

[0249] In the embodiment, during the movement of the focusing holder 41 relative to the anti-shake holder 21, the movement direction of the focusing holder 41 is perpendicular to the magnetic gap between the focusing magnetic member 422 and the focusing coil 421, and the magnetic gap is not affected by the movement of the focusing holder 41. Therefore, the problem of rapid decline of driving force caused by increase of the magnetic gap can be avoided, so as to ensure that the focusing driving force of the motor 1 is large and stable, which is conducive to the large-stroke design of the focusing function of the motor 1.

[0250] In the embodiment, the focusing driving mechanism 42, the first anti-shake driving mechanism 22a, and the second anti-shake driving mechanism 22b of the motor 1 are all moving magnet designs, and the driving of the motor 1 in the first direction (i.e., the X-axis direction), the second direction (i.e., the Y-axis direction), and the third direction (i.e., the Z-axis direction) is controlled by a group of driving components (including coils and magnetic members) alone. During the movement of the focusing holder 41 of the motor 1 relative to the anti-shake holder 21 along the third direction for automatic focusing, the relative position of the anti-shake holder 21 and the base 10 is not affected, and the magnetic gap width of the first anti-shake driving mechanism 22a and the second anti-shake driving mechanism 22b is not easily changed. Similarly, during the movement of the anti-shake holder 21 relative to the base 10 along the first direction and / or the second direction for optical anti-shake, the focusing holder 41 moves with the anti-shake holder 21, and the relative position of the two is not affected, and the magnetic gap width of the focusing driving mechanism 42 is not easily changed. Therefore, the focusing driving mechanism 42, the first anti-shake driving mechanism 22a, and the second anti-shake driving mechanism 22b of the motor 1 are decoupled and do not interfere with each other during movement, which is conducive to ensuring the driving accuracy of the motor 1.

[0251] In addition, since the focusing bracket 41 is located inside the anti-shake bracket 21, the focusing coil 421 is fixed to the anti-shake bracket 21, and the focusing magnetic piece 422 is fixed to the focusing bracket 41, the moving assembly of the optical anti-shake of the motor 1 wraps the moving assembly of the focusing. It can be understood that when the focusing bracket 41 is located inside the anti-shake bracket 21, the anti-shake bracket 21 can be arranged around the focusing bracket 41. The surrounding can be that the anti-shake bracket 21 is arranged around the focusing bracket 41 once, or the anti-shake bracket 21 is arranged around the focusing bracket 41 in part. In the embodiment, the anti-shake bracket 21 is annular. At this time, the anti-shake bracket 21 is arranged around the focusing bracket 41.

[0252] It can be understood that in some schemes, the anti-shake bracket 21 is located inside the focusing bracket 41. At this time, when the camera module 100 needs to focus, the focusing bracket 41 needs to drive the anti-shake bracket 21 and the lens 2 to move along the third direction. The weight of the moving assembly composed of the focusing bracket 41, the anti-shake bracket 21 and the lens 2 is heavy, so as to cause the focusing driving mechanism 42 to increase the driving force by increasing the volume. Therefore, this setting is not conducive to the lightweight and small design of the motor 1. In the embodiment, the focusing bracket 41 is arranged inside the anti-shake bracket 21. At this time, when the camera module 100 needs to focus, the focusing bracket 41 needs to drive the lens 2 to move along the third direction. Therefore, the moving assembly in the focusing process of the embodiment can omit the anti-shake bracket 21, that is, the weight of the moving assembly composed of the focusing bracket 41 and the lens 2 is light, so as to be conducive to the small design of the focusing driving mechanism 42. The motor 1 of the embodiment can realize the lightweight and small design.

[0253] It can be understood that compared with the scheme that the anti-shake bracket 21 is inside the focusing bracket 41, the anti-shake bracket 21 needs at least two anti-shake driving assemblies to drive the anti-shake bracket 21 to move in the X-Y plane. Therefore, the motor 1 needs to arrange at least two sets of lines to provide signals and power for the anti-shake driving assembly. Moreover, the at least two sets of lines need to pass through the focusing bracket 41. Therefore, the power supply scheme of the scheme is relatively complex, which increases the difficulty of the setting of the motor 1. In the embodiment, the focusing bracket 41 is arranged inside the anti-shake bracket 21. Since the focusing bracket 41 needs a focusing driving mechanism 42 to drive the focusing bracket 41 to move along the third direction, the motor 1 needs a set of lines to provide signals and power for the focusing driving mechanism 42, that is, a set of lines passes through the anti-shake bracket 21. Therefore, the power supply scheme of the scheme of the embodiment is relatively simple, which can greatly reduce the difficulty of the setting of the motor 1.

[0254] In the embodiment, the winding plane of the focusing coil 421 can be parallel to the third direction. At this time, the focusing coil 421 is arranged vertically, so that the focusing coil 421 can occupy a smaller area in the X-Y plane, thereby facilitating the miniaturization of the motor 1. The focusing magnetic member 422 can include two opposite polarity directions, both of which are perpendicular to the third direction. At this time, the focusing magnetic member 422 can be arranged vertically, thereby reducing the occupied space of the focusing magnetic member 422 in the X-Y plane, facilitating the miniaturization design of the motor 1.

[0255] Referring to FIG. 27, in some embodiments, the focusing magnetic member 434 (see FIG. 22) can be fixed between the fourth edge portion 211d of the anti-shake bracket 21 and the focusing circuit board 431. For example, the fourth edge portion 211d of the anti-shake bracket 21 can be provided with a third mounting groove 2114d, and at least part of the focusing magnetic member 434 can be located in the third mounting groove 2114d of the fourth edge portion 211d. For example, the focusing magnetic member 434 can be arranged to face the focusing magnetic member 422 to generate a magnetic attraction force with the focusing magnetic member 422, so that the focusing bracket 41 has a tendency to approach the anti-shake bracket 21, thereby ensuring that the guide rod 44 and the sliding groove 413 remain in contact, achieving pre-tightening, and improving the reliability of the focusing process of the motor. It can be understood that the focusing magnetic member 434 can be located on the side of the focusing circuit board 431 away from the focusing coil 421. In the X-axis direction, the focusing magnetic member 434 at least partially overlaps the focusing magnetic member 422.

[0256] In the embodiment, since the focusing bracket 41 has a tendency to approach the fourth edge portion 211d of the anti-shake bracket 21 under the magnetic force, it can be ensured that the focusing bracket 41 remains in contact with the guide rod 44 (including the first guide rod 441 and the second guide rod 442), so that accurate guidance can be achieved during the movement of the focusing bracket 41 relative to the anti-shake bracket 21, thereby improving the reliability and accuracy of optical focusing, and facilitating the large-stroke design of the focusing function of the motor 1.

[0257] For example, the number of focusing magnetic members 434 can be one or more. When the number of focusing magnetic members 434 is one, the focusing magnetic member 434 can be located in the middle of the fourth edge portion 211d of the anti-shake bracket 21; when the number of focusing magnetic members 434 is more than one, the plurality of focusing magnetic members 434 can be arranged at intervals on the fourth edge portion 211d of the anti-shake bracket 21.

[0258] For example, the focusing magnetic member 434 can be made of a material capable of generating a magnetic attraction force with a magnet or other magnetic component, such as a ferromagnetic material such as steel.

[0259] Please refer to FIG. 28 and FIG. 29, FIG. 28 is a partial cross-sectional structure schematic diagram of the motor 1 shown in FIG. 26 along G-G, and FIG. 29 is a partial cross-sectional structure schematic diagram of the motor 1 shown in FIG. 26 along H-H.

[0260] In some embodiments, the focusing magnetic piece 422 is arranged opposite to the focusing coil 421. At this time, the sliding groove 413 of the focusing support 41 is arranged corresponding to the fixing groove 2118 of the anti-shake support 21, and a part of the guide rod 44 can be located in the sliding groove 413, and a part of the guide rod 44 can be located in the fixing groove 2118. For example, the first sliding groove 4131 is arranged corresponding to the first fixing groove 2118a, and the second sliding groove 4132 is arranged corresponding to the second fixing groove 2118b. A part of the first guide rod 441 is located in the first fixing groove 2118a of the anti-shake support 21, and a part of the first guide rod 441 is located in the first sliding groove 4131; a part of the second guide rod 442 is located in the second fixing groove 2118b, and a part of the second guide rod 442 is located in the second sliding groove 4132. It can be understood that the focusing support 41 can be slidably connected to the anti-shake support 21 through the first guide rod 441 and the second guide rod 442, and the relative sliding direction of the two is parallel to the guide direction (i.e. the third direction) of the guide rod 44, so that the focusing support 41 drives the lens 2 to move in the third direction to realize focusing, which is beneficial to realize the large stroke design of the focusing function of the motor 1. Moreover, the focusing support 41 can be slidably connected to the anti-shake support 21 through the cooperation of the guide rod 44 and the sliding groove 413, so that the focusing support 41 has good stability during movement relative to the anti-shake support 21. In addition, the first guide rod 441 and the second guide rod 442 can also be used to bear the focusing support 41, which is beneficial to realize the large load design of the focusing function of the motor 1. In other embodiments, the focusing support 41 can also be slidably connected to the anti-shake support 21 through a plurality of balls, and the arrangement direction of the plurality of balls is the guide direction.

[0261] In some embodiments, the cooperation between the guide rod 44 and the focusing holder 41 includes tight cooperation and loose cooperation to reduce assembly difficulty. For example, among the first sliding groove 4131 and the second sliding groove 4132 of the focusing holder 41, at least one "V"-shaped groove and at least one "U"-shaped groove or "L"-shaped groove are included. When the "V"-shaped groove cooperates with the guide rod 44, the side groove wall of the "V"-shaped groove contacts the guide rod 44 to achieve tight cooperation. For example, the first sliding groove 4131 can be a "V"-shaped groove, the first groove wall 4133 and the second groove wall 4134 of the first sliding groove 4131 contact the first guide rod 441, and tight cooperation is achieved between the first guide rod 441 and the first sliding groove 4131. When the "U"-shaped groove or "L"-shaped groove cooperates with the guide rod 44, the groove wall of the "U"-shaped groove or "L"-shaped groove contacts the guide rod 44 to achieve loose cooperation. For example, the second sliding groove 4132 can be a "L"-shaped groove, the third groove wall 4135 of the second sliding groove 4132 contacts the second guide rod 442, and loose cooperation is achieved between the second guide rod 442 and the second sliding groove 4132.

[0262] It can be understood that in other embodiments, the tight cooperation and loose cooperation design between the guide rod 44 and the focusing holder 41 or the anti-shake holder 21 can have other implementation schemes, and the embodiments of the present application do not strictly limit this.

[0263] In other embodiments, the guide rod 44 can also be fixedly connected to the focusing holder 41 and slidably connected to the anti-shake holder 21. At this time, the anti-shake holder 21 can be provided with a sliding groove. The focusing holder 41 can move relative to the anti-shake holder 21 along the third direction through the guide rod and the sliding groove.

[0264] In some embodiments, the surface of the guide rod 44 can be provided with a lubricating film. For example, the surface of the first guide rod 441 in contact with the first sliding groove 4131 can be provided with a lubricating film. The surface of the second guide rod 442 in contact with the second sliding groove 4132 can be provided with a lubricating film. It can be understood that in mechanical work, the lubricating film between the friction pair is often in a thin film lubrication state with a thickness of several to dozens of nanometers, and the surface roughness and thickness of the lubricating film are in the same order of magnitude. For example, the lubricating film can be a multiphase nanocomposite film or other thin film with low friction coefficient.

[0265] In the present embodiment, by providing the lubricating film on the surface of the guide rod 44, the friction coefficient between the guide rod 44 and the sliding groove 413 can be reduced during the sliding process of the guide rod 44 relative to the sliding groove 413, so that the movement of the focusing holder 41 relative to the anti-shake holder 21 along the third direction is smoother.

[0266] In some embodiments, the groove wall of the sliding groove 413 can be provided with a lubricating film, so as to reduce the friction coefficient between the guide rod 44 and the sliding groove 413, and make the movement of the focusing bracket 41 relative to the anti-shake bracket 21 along the third direction more smooth. For example, the groove wall of the first sliding groove 4131 in contact with the first guide rod 44 can be provided with a lubricating film. The groove wall of the second sliding groove 4132 in contact with the second guide rod 44 can be provided with a lubricating film.

[0267] In some embodiments, the guide rod 44 is made of ceramic material. By making the guide rod 44 of ceramic material, the manufacturing cost of the guide rod 44 can be effectively reduced, and the mass of the guide rod 44 can be reduced, so that the guide rod 44 can be firmly fixed on the anti-shake bracket 21 or the focusing bracket 41 by means of gluing, and the manufacturing difficulty of the motor 1 can also be reduced.

[0268] It can be understood that the features in the embodiments of the present application can be combined with each other without conflict, and any combination of the features in different embodiments is also within the protection scope of the present application, that is, the above-described multiple embodiments can also be combined as needed. It can be understood that all the above drawings are exemplary illustrations of the present application, and do not represent the actual size of the product. The size ratio relationship between the components in the drawings is not limited to the actual product of the present application.

[0269] The above is only some embodiments of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
