Description

Motors, camera modules and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 2, 2024, with application number 202410011124.3, and priority to the Chinese patent application with the invention name “Motor, camera module and electronic device”, all contents of which are incorporated by reference into this application. Technical Field

[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 Art

[0003] Electronic devices often include a camera module for capturing images. When taking photos or videos, the camera module may experience vibrations that affect the image quality captured by the image sensor.

[0004] Many anti-shake technologies have emerged on the market, such as Optical Image Stabilization (OIS). Based on the detected shake, the OIS motor drives the lens to perform compensatory movement in a plane perpendicular to the optical axis to offset the shake and achieve anti-shake. However, when a traditional motor drives the lens in one direction, it also produces additional displacement in other directions. This results in low control precision for optical image stabilization and poor motor reliability. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a motor, a camera module and an electronic device, aiming to provide a motor with a simple overall structure, high control accuracy and reliability.

[0006] In the first aspect, the present application provides a motor. The motor includes a base, an anti-shake bracket, a first anti-shake magnetic part, a second anti-shake magnetic part, a first anti-shake coil, a second anti-shake coil, a compensation coil and a compensation magnetic part. The anti-shake bracket includes a first side portion, a second side portion and a connecting section connected in sequence. The first side portion and the second side portion are arranged at an angle. The first anti-shake magnetic part is fixed to the first side portion, and the second anti-shake magnetic part is fixed to the second side portion. The first anti-shake coil and the second anti-shake coil are both fixed to the base. The first anti-shake coil faces the first anti-shake magnetic part and is used to drive the anti-shake bracket to move relative to the base in a first direction. The second anti-shake coil is used to drive the anti-shake bracket to move relative to the base in a first direction. The coil faces the second anti-shake magnetic component and is used to drive the anti-shake bracket to move relative to the base along the second direction, and the second direction intersects with the first direction; the compensation magnetic component is fixed to the anti-shake bracket, and the compensation coil is fixed to the base, and the compensation coil is arranged facing the compensation magnetic component; the first anti-shake magnetic component has a first axis, the first axis passes through the center of the first anti-shake magnetic component and is parallel to the first direction; the second anti-shake magnetic component also has a second axis, the second axis passes through the center of the second anti-shake magnetic component and is parallel to the second direction; the center of the compensation magnetic component is staggered with the first axis and the second axis.

[0007] It can be understood that when the anti-shake bracket moves relative to the base in the first direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the first anti-shake magnetic component and the first anti-shake coil. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, it can avoid the problem of rapid decrease in driving force caused by the increase in the magnetic gap, thereby ensuring that the anti-shake driving force of the motor is large and the driving force is relatively stable, which is conducive to the long-stroke design of the motor's optical anti-shake function.

[0008] It can be understood that when the anti-shake bracket moves relative to the base in the second direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the second anti-shake magnetic part and the second anti-shake coil. The above magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, it can avoid the problem of rapid decrease in driving force caused by the increase in the magnetic gap, thereby ensuring that the anti-shake driving force of the motor is large and the driving force is relatively stable, which is conducive to the large-stroke design of the motor's optical anti-shake function.

[0009] When the anti-shake bracket moves in the first direction or the second direction relative to the base, the compensating magnetic component can be used to provide a first force, wherein, since the center of the compensating magnetic component is staggered with the first axis and the second axis, that is, the center of the compensating magnetic component is not on the first axis, and the center of the compensating magnetic component is not on the second axis, the first force can generate a compensating torque relative to the anti-shake bracket to balance the effect of the friction torque of the anti-shake bracket, ensuring that the resultant torque applied to the anti-shake bracket can be maintained at zero, and preventing the anti-shake bracket from rotating relative to the base due to the non-zero resultant torque applied, thereby affecting the control accuracy and reliability of the motor.

[0010] In one possible implementation, the compensating magnetic member is staggered with both the first and second axes. This ensures that the center of the compensating magnetic member is staggered with both the first and second axes, while also increasing the torque of the compensating magnetic member.

[0011] In one possible implementation, the connecting section includes a third side and a fourth side, the third side being connected between the second side and the fourth side, the first side being arranged opposite the third side, and the second side being arranged opposite the fourth side; and the compensating magnetic member being fixed to the third side or the fourth side. In this case, the compensating magnetic member, the first anti-shake magnetic member, and the second anti-shake magnetic member can be roughly L-shaped. In this embodiment, the first anti-shake magnetic member, the first anti-shake coil, the second anti-shake coil, and the second anti-shake magnetic member are arranged on two sides of the motor corresponding to the first and second sides of the anti-shake bracket. The side of the motor corresponding to the third side of the anti-shake bracket is used to arrange the compensating magnetic member and the compensating coil, and the side corresponding to the fourth side of the anti-shake bracket does not have any structural components arranged thereon. Therefore, the motor can fully utilize its three sides, while minimizing the volume of the remaining side, thereby facilitating the overall miniaturization of the motor.

[0012] In one possible implementation, the compensating magnetic component is located on the side of the first axis near the second anti-shake magnetic component. It is understood that placing the compensating magnetic component near the second anti-shake magnetic component can improve the utilization of the space on the side of the first axis near the second anti-shake magnetic component, facilitating the miniaturization of the motor design.

[0013] In a possible implementation, a winding plane of the compensation coil is perpendicular to a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0014] It can be understood that when the anti-shake bracket moves relative to the base in the first direction or the second direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the compensation magnetic component and the compensation coil. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, it can avoid the problem of rapid decrease in driving force due to increase in magnetic gap, thereby ensuring that the driving force provided by the compensation magnetic component is large and the driving force is relatively stable.

[0015] At this time, the compensation coil is arranged horizontally, which is beneficial to reducing the space occupied by the compensation coil in the third direction and is beneficial to achieving a thinner setting of the motor.

[0016] In a possible implementation, the compensating magnetic element is composed of one or more magnets, or the compensating magnetic element is a Halbach magnet array.

[0017] In one possible implementation, the length of the compensating magnetic component is shorter than both the first and second anti-shake magnetic components. This reduces the space occupied by the compensating magnetic component within the motor, facilitating motor miniaturization and reducing manufacturing costs.

[0018] In one possible implementation, the motor also includes a first position sensor, a second position sensor and a third position sensor; the first position sensor is fixed to the base to detect the first magnetic field change of the first anti-shake magnetic component when the anti-shake bracket moves along the first direction; the second position sensor is fixed to the base to detect the second magnetic field change of the second anti-shake magnetic component when the anti-shake bracket moves along the second direction; the third position sensor is fixed to the base to detect the third magnetic field change of the compensation magnetic component when the anti-shake bracket moves along the first direction, and obtain the deflection of the anti-shake bracket based on the third magnetic field change and the first magnetic field change, and also to detect the fourth magnetic field change of the compensation magnetic component when the anti-shake bracket moves along the second direction, and obtain the deflection of the anti-shake bracket based on the fourth magnetic field change.

[0019] It can be understood that when the anti-shake bracket moves along the first direction, the first position sensor can detect the change in the first magnetic field of the first anti-shake magnetic component, and the third position sensor can detect the change in the third magnetic field of the compensation magnetic component. If the anti-shake bracket is deflected, it will cause different displacements of the two opposite sides of the anti-shake bracket in the first direction. At this time, the change in the first magnetic field will be unequal to the change in the third magnetic field. The deflection of the anti-shake bracket can be obtained based on the difference between the change in the first magnetic field and the change in the third magnetic field.

[0020] In this embodiment, when the anti-shake bracket moves along the second direction, the second position sensor can detect the change in the second magnetic field of the second anti-shake magnetic component, and the third position sensor can detect the change in the fourth magnetic field of the compensation magnetic component. If the anti-shake bracket is deflected, it will cause the anti-shake bracket to be displaced in the second direction. At this time, the change in the fourth magnetic field will not be zero, and the deflection of the anti-shake bracket can be obtained based on the change in the fourth magnetic field.

[0021] In one possible implementation, the motor further includes a ball group, through which the anti-shake bracket is movably connected to the base, with the ball group and the compensation coil spaced apart. Each ball group may include multiple balls, with the number of balls ranging from five, sixteen, or thirty-two, etc., though this application is not limited thereto. This embodiment utilizes a ball group to achieve a flexible connection between the anti-shake bracket and the focus bracket, ensuring sufficient support force while reducing frictional resistance between the balls and the anti-shake bracket. This reduces the required driving force during movement of the anti-shake bracket, facilitating a reduction in the size of the first magnetic member and / or the first anti-shake coil, thereby miniaturizing the motor. For example, compared to conventional large balls, the smaller diameter of each ball in this embodiment's ball group also facilitates shortening the distance between the anti-shake bracket and the base, facilitating a thinner motor. Furthermore, the ball group provides multi-point support for the anti-shake bracket, distributing stress and preventing deformation of the balls due to excessive force concentration in a single direction during impact. This improves the reliability of the ball group's support of the anti-shake bracket and other structural components, such as the lens.

[0022] In one possible implementation, the motor includes a first ball group, a second ball group, and a third ball group; the first ball group is connected to the junction of the first and second sides, the second ball group is connected to the junction of the second and third sides, and the third ball group is connected to the junction of the fourth side and the first side; the compensating magnetic member is positioned near the second ball group. The first, second, and third ball groups can provide multi-point support for the anti-shake bracket, improving the stability of the relative positional relationship between the anti-shake bracket and the ball groups, making the movement of the anti-shake bracket safer and more reliable. In this embodiment, the ball groups are arranged using the principle of triangular stability, which ensures the reliability of the ball groups while reducing the number of ball groups within the motor, thereby simplifying the motor structure. In other embodiments, the ball group may not include the third ball group; alternatively, the ball group may include a fourth ball group, which is not limited in this application.

[0023] In one possible implementation, the base includes a base plate and a first metal member, the first metal member being embedded in the base plate; the base plate having a groove, the first metal member including a support portion made of a metal material, at least a portion of the support portion being exposed relative to the groove, the ball assembly being located within the groove and in contact with the support portion. For example, the first metal member may be made of a steel sheet or other material, although this application does not limit this.

[0024] It can be understood that by setting up a support part and movably connecting the ball group to the support part, the friction force exerted on the ball group during movement can be reduced, and the smoothness of the ball rotation process can be improved, which is beneficial to improving the response rate of the motor when the anti-shake bracket is movably connected to the base through the ball group.

[0025] In one possible implementation, the first metal member further includes a reinforcement portion connected to the support portion and located on a side of the support portion away from the ball assembly. It is understood that the reinforcement portion can provide a certain degree of rigidity and support to the base, thereby increasing its strength and preventing deformation.

[0026] In one possible implementation, the motor further includes a first anti-shake magnetic component, which is fixed to the base and disposed facing the first anti-shake magnetic component to generate a magnetic attraction with the first anti-shake magnetic component, thereby causing the anti-shake bracket to be attached to the base; and / or the motor further includes a second anti-shake magnetic component, which is fixed to the base and disposed facing the second anti-shake magnetic component to generate a magnetic attraction with the second anti-shake magnetic component, thereby causing the anti-shake bracket to be attached to the base. The magnetic force between the first anti-shake magnetic component and the first anti-shake magnetic component, and the magnetic force between the second anti-shake magnetic component and the second anti-shake magnetic component, causes the anti-shake bracket to tend to approach the base, thereby ensuring contact between the base, the ball assembly, and the anti-shake bracket, achieving pre-tightening, and improving the reliability of the motor's optical image stabilization process.

[0027] In one possible implementation, the motor also includes a focusing bracket, which is located on the inner side of the anti-shake bracket and is movably connected to the anti-shake bracket; a focusing magnetic part, which is fixed to the anti-shake bracket; and a focusing coil, which is fixed to the focusing bracket and is arranged facing the focusing magnetic part to drive the focusing bracket to move relative to the base along a third direction, where the third direction intersects with the first direction.

[0028] It is understandable that by arranging the focus bracket to be located inside the anti-shake bracket, the focus coil is fixed to the anti-shake bracket, and the focus magnetic part is fixed to the focus bracket, the optical image stabilization motor component wraps around the focus movable component. When the focus bracket is located inside the anti-shake bracket, the anti-shake bracket can be arranged around the focus bracket. Surrounding can mean that the anti-shake bracket is arranged around the focus bracket all the way around, or it can be arranged around a portion of the anti-shake bracket around the focus bracket. In this embodiment, the anti-shake bracket is frame-shaped. In this case, the anti-shake bracket is arranged around the focus bracket.

[0029] It is understandable that in some solutions, the anti-shake bracket is located on the inner side of the focus bracket. At this time, when the camera module needs to focus, the focus bracket needs to drive the anti-shake bracket and the lens to move along the third direction. In this way, the weight of the mover composed of the focus bracket, the anti-shake bracket and the lens is heavy, which causes the focus drive assembly to increase the driving force by increasing the volume. Therefore, this setting is not conducive to the lightweight and miniaturized design of the motor. In this embodiment, the focus bracket is set on the inner side of the anti-shake bracket. At this time, when the camera module needs to focus, the focus bracket needs to drive the lens to move along the third direction. In this way, the mover in the focusing process of this embodiment can omit the anti-shake bracket, that is, the weight of the mover composed of the focus bracket and the lens is lighter, which is conducive to the miniaturization of the focus drive assembly. The motor of this embodiment can achieve lightweight and miniaturized settings.

[0030] It is understandable that, compared to the solution in which the anti-shake bracket is on the inner side of the focusing bracket, the anti-shake bracket requires at least two anti-shake drive components to push the anti-shake bracket to move in the XY plane. In this way, the motor needs to arrange at least two sets of lines to provide signals and power to the anti-shake drive components. And at least two sets of lines need to pass through the focusing bracket. Therefore, the power-on setting of this solution is relatively complicated, which increases the difficulty of setting up the motor. In this embodiment, by setting the focusing bracket on the inner side of the anti-shake bracket, since the focusing bracket requires a set of focus drive components to push the focusing bracket to move along the third direction, the motor also needs a set of lines to provide signals and power to the focus drive components, that is, a set of lines needs to pass through the anti-shake bracket. Therefore, the power-on scheme of the solution of this embodiment is relatively simple, which can greatly reduce the difficulty of setting up the motor.

[0031] Among them, the plane on which the wire of the focusing coil is wound (that is, the winding plane) can be parallel to the third direction. At this time, the focusing coil is arranged vertically, so that the focusing coil can occupy a smaller area in the plane perpendicular to the optical axis, which is beneficial to the miniaturization of the motor. The focusing magnetic part can include two opposite polarity directions, both polarity directions are perpendicular to the third direction. At this time, the focusing magnetic part can be arranged vertically, thereby reducing the space occupied by the focusing magnetic part in the motor, facilitating the miniaturization design of the motor.

[0032] In one possible implementation, the motor further includes four suspension wires, each of which includes a first fixed end and a second fixed end. The first fixed ends of the four suspension wires are correspondingly fixed to the four corners of the base, and the second fixed ends of the four suspension wires are correspondingly connected to the four positions of the anti-shake bracket. In other words, the suspension wires can be correspondingly fixed to the four corners of the anti-shake bracket.

[0033] It can be understood that by setting the suspension wires, an elastic connection between the base and the anti-shake bracket can be achieved. When the anti-shake bracket moves relative to the base, the four suspension wires will undergo elastic deformation. The combined force direction of the restoring force generated by the four suspension wires is in the opposite direction of the movement direction of the anti-shake bracket, so as to drive the anti-shake bracket to move in the opposite direction relative to the base, so that the anti-shake bracket moves back to the equilibrium position, which can improve the linearity of the anti-shake bracket movement, and can also help maintain the center of the anti-shake bracket in the direction of the optical axis, thereby improving the reliability and control accuracy of the motor.

[0034] In one possible implementation, the motor also includes a focus driver chip, multiple wirings and multiple reeds, the focus driver chip is fixed to the anti-shake bracket, the multiple wirings are embedded in the anti-shake bracket at intervals, and the multiple reeds are fixed to the anti-shake bracket at intervals; the access ends of the multiple wirings are electrically connected to the multiple ports of the focus driver chip one by one, and the first connection ends of the multiple reeds are electrically connected to the output ends of the multiple wirings one by one; the base includes a bottom plate and four conductive parts, and the conductive parts are embedded in the bottom plate at intervals; the second connection ends of the multiple reeds are electrically connected to the four conductive parts through four suspension wires one by one. Exemplarily, the routing may include a first routing, a second routing, a third routing and a fourth routing, the reeds may include a first reed, a second reed, a third reed and a fourth reed, the suspension wire may include a first suspension wire, a second suspension wire, a third suspension wire and a fourth suspension wire, the four routings may serve as transmission channels between the four reeds and the four ports of the focus driver chip respectively, the four reeds may serve as transmission channels between the four routings and the four suspension wires respectively, so as to realize the "one thing for multiple uses" of the suspension wire, the circuit inside the motor is simple, and the utilization rate of components is high, which is conducive to reducing costs and realizing the miniaturization of the motor.

[0035] In one possible implementation, the base is provided with mounting holes, with four mounting holes located at the four corners of the base; the conductive member is provided with through-holes, with the four through-holes corresponding to the four mounting holes, and the through-holes are exposed relative to the mounting holes, and the first fixed ends of the four suspension wires extend into the through-holes in a one-to-one correspondence. In one embodiment, by providing a tight fit between the suspension wires and the mounting holes and the through-holes, the suspension wires and the base, as well as the suspension wires and the conductive member, are stably connected, and the base can limit the first fixed ends of the suspension wires, ensuring the reliability of the electrical connection between the suspension wires and the conductive member.

[0036] In one possible implementation, the motor further includes a guide rod, which is fixed to an anti-shake bracket or a focus bracket; the focus bracket is slidably connected to the anti-shake bracket via the guide rod, and the guide rod is made of a ceramic material. For example, there can be two guide rods, and the shape, size, and material of the two guide rods can be the same or different. By making the guide rods out of ceramic material, the manufacturing cost and weight of the guide rods can be effectively reduced, allowing them to be securely fixed to the anti-shake bracket or the focus bracket by gluing or other means, which also helps to reduce the manufacturing difficulty of the motor.

[0037] In one possible implementation, the motor further includes a first buffer member connected to the side of the focus bracket facing away from the base; and / or the motor further includes a second buffer member connected to the side of the focus bracket facing the base; and / or the motor further includes a third buffer member connected to the outer surface of the anti-shake bracket. It is understood that the first, second, and third buffer members can all be made of flexible materials such as liquid silicone or foam. The provision of the first and / or second buffer members reduces the impact force between the focus bracket and the motor housing or base when the focus bracket moves upward in the third direction, preventing damage or displacement of the lens due to direct collision between the focus bracket and the motor housing or base, thereby improving the reliability of the motor. The provision of the third buffer member reduces the impact force between the anti-shake bracket and the motor housing when the anti-shake bracket moves in the first or second direction, preventing damage or displacement of the lens due to direct collision between the anti-shake bracket and the motor housing, thereby improving the reliability of the motor.

[0038] In a second aspect, embodiments of the present application further provide a camera module. The camera module includes a lens, an image sensor, and any of the aforementioned motors. The lens is mounted within the motor, the image sensor is located on the light-emitting side of the lens, and the motor is fixedly connected to the image sensor. The camera module in this embodiment has high imaging quality and control accuracy.

[0039] In one possible implementation, the camera module also includes a variable aperture located on the light-entering side of the lens. The variable aperture has an aperture whose size can be automatically adjusted. Light enters the lens through the aperture of the variable aperture. The variable aperture is used to adjust the amount of light entering, allowing the camera module to maintain consistent image quality under various brightness conditions.

[0040] In a third aspect, embodiments of the present application further provide an electronic device. The electronic device includes a device housing and any of the aforementioned camera modules, wherein the camera module is disposed within the device housing. The camera module has excellent image quality and control accuracy, thereby improving the image capture performance of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0086] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. "Sliding connection" means that the two are connected to each other and can slide relative to each other after the connection. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0087] "Multiple" means at least two. A and / or B include three schemes, specifically Scheme A, Scheme B and Scheme AB. Among them, "electrical connection" means that electrical signals can be conducted between each other. In addition, the two components are integrated into an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection).

[0088] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0089] In addition, in the embodiments of the present application, the mathematical concepts mentioned, such as parallel and perpendicular, are all in terms of the current state of the art, rather than being absolutely strict definitions in a mathematical sense. A small amount of deviation is allowed, and being approximately parallel or approximately perpendicular is acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0090] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0091] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0092] As shown in FIG1 , in some embodiments, electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 in the embodiment shown in FIG1 is described using a mobile phone as an example.

[0093] FIG2 is a partial cross-sectional schematic diagram of the electronic device 1000 shown in FIG1 taken along line AA in some embodiments.

[0094] As shown in Figures 1 and 2, in some embodiments, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module 100 or a front camera module 100. It should be noted that Figure 1 and the related figures below only schematically illustrate 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 Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0095] The device housing 200 may 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 may be fixed to the frame 201 by gluing, snapping, or the like. The back cover 202 may also be integrally formed with the frame 201, i.e., the back cover 202 and the frame 201 form a single, integral structure.

[0096] In some embodiments, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on either side of the frame 201. The screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 can be flat or curved.

[0097] For example, the camera module 100 can be located inside the electronic device 1000. The camera module 100 can be located on the 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 interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 203. The camera module 100 can capture the light entering the interior of the electronic device 1000.

[0098] FIG3 is a schematic structural diagram of some embodiments of the camera module 100 shown in FIG1 , and FIG4 is a schematic partial decomposition diagram of some embodiments of the camera module 100 shown in FIG3 .

[0099] As shown in Figures 3 and 4, the camera module 100 includes a motor 1, a lens 2, a module circuit board 3, an image sensor 4, a filter holder 5a, a filter 5b, an iris 6, and a module housing 7. The image sensor 4, also known as a photosensitive chip or a photosensitive element, collects ambient light and converts the image information carried by the ambient light into electrical signals.

[0100] It is understood that the camera module 100 may include fewer or more structures. For example, the camera module 100 may include fewer structures. For example, the camera module 100 may not include the filter holder 5a, and / or the filter 5b, and / or the variable aperture 6, and / or the module housing 7.

[0101] It will be understood that, for ease of description, the camera module 100 will be defined as having a first direction Y, a second direction X, and a third direction Z. The first direction Y may be the width direction of the camera module 100, the second direction X may be the length direction of the camera module 100, and the second direction X is perpendicular to the first direction Y. The third direction Z may be the height direction of the camera module 100, and the third direction Z is perpendicular to the first direction Y and the second direction X. In other embodiments, the coordinate system of the camera module 100 may be flexibly configured according to specific practical needs.

[0102] FIG5 is a partial cross-sectional schematic diagram of the camera module 100 shown in FIG3 taken along line BB in some embodiments.

[0103] As shown in Figure 5, the module housing 7 is fixed on the module circuit board 3, and together with the module circuit board 3, encloses an accommodating space 70. The motor 1, lens 2, image sensor 4, filter holder 5a and filter 5b can all be located in the accommodating space 70. The module housing 7 covers at least part of the motor 1, and a part of the lens 2 can extend to the outside of the module housing 7 through the opening of the module housing 7. The module housing 7 can be used to protect the structural parts in the camera module 100.

[0104] As shown in Figure 5, 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.

[0105] Illustratively, the filter holder 5a is fixedly connected to the module circuit board 3. The filter holder 5a and the image sensor 4 are located on the same side of the module circuit board 3. The filter holder 5a is provided with a light passage 51a. The filter 5b is fixedly connected to the filter holder 5a. The filter 5b can be located within the light passage 51a. The filter 5b is also positioned opposite the image sensor 4. The filter 5b can be used to filter infrared light, blue light, and other light from light entering the image sensor 4, thereby ensuring that the image sensor 4 has excellent imaging quality.

[0106] As shown in Figure 5, the motor 1 can be fixed to the module circuit board 3. The motor 1 and the image sensor 4 are 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-emitting side of the lens 2. It is understood that in the third direction Z, the image sensor 4, the optical filter 5b, and the lens 2 are arranged in sequence. In this case, the image sensor 4 is located on the light-emitting side of the lens 2. The optical filter 5b is located between the lens 2 and the image sensor 4.

[0107] It is understood that 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 Z of the camera module 100. The optical axis direction of the lens 2 is the same as the optical axis direction of the camera module 100.

[0108] It can be understood that compared with the solution of fixing the motor 1 on the filter holder 5a, this embodiment can avoid the stacking of the motor 1 and the filter holder 5a in the third direction Z by fixing the motor 1 on the module circuit board 3, that is, the motor 1 and the filter holder 5a can be staggered in the XY plane, thereby greatly reducing the height of the camera module 100.

[0109] It is understandable that the motor 1 can be a focus motor 1. In this way, the motor 1 can achieve auto focus (AF) by controlling the movement of the lens 2 along the third direction Z. The motor 1 can also be an anti-shake motor 1. In this way, the motor 1 can control the movement of the lens 2 along a plane perpendicular to the third direction Z (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the lens 2 on the XY plane can be controlled by the motor 1 to offset the shaking stroke of the lens 2 on the XY plane 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 movement of the lens 2 on the XY plane by the motor 1 to achieve 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 integrated anti-shake and focus motor 1. In this way, the motor 1 can achieve both autofocus and optical image stabilization by controlling the lens 2. This embodiment is described by taking the motor 1 as an example of an integrated anti-shake and focus motor 1.

[0110] 3 and 4 , the variable aperture 6 may be located on the light-entering side of the lens 2. In the third direction Z, the image sensor 4, the filter 5b, the lens 2, and the variable aperture 6 are arranged in sequence.

[0111] It is understood that the variable aperture 6 has an aperture 6a whose size can be automatically adjusted. Light can enter the lens 2 through the aperture 6a of the variable aperture 6. The variable aperture 6 is used to adjust the amount of light entering, so that the camera module 100 can maintain consistent shooting quality under various brightness conditions.

[0112] The above text generally introduces the structure of the camera module 100 in conjunction with the relevant drawings. The following text will specifically introduce the structure of the motor 1 in conjunction with the relevant drawings.

[0113] FIG. 6 is a partially exploded schematic diagram of the motor 1 shown in FIG. 4 in some embodiments.

[0114] As shown in FIG6 , the motor 1 includes a base 11 , a suspension wire 12 , a spring 13 , a motor housing 14 , an anti-shake driving module 20 and a focus driving module 30 .

[0115] For example, the anti-shake drive module 20 may include an anti-shake bracket 21, a first anti-shake drive mechanism 22a, a second anti-shake drive mechanism 22b, a compensation mechanism 23, and a ball group 24. The first anti-shake drive mechanism 22a includes a first anti-shake coil 221 and a first anti-shake magnetic component 222, while the second anti-shake drive mechanism 22b includes a second anti-shake coil 223 and a second anti-shake magnetic component 224. The compensation mechanism 23 includes a compensation coil 231 and a compensation magnetic component 232.

[0116] Exemplarily, the focus drive module 30 may include a focus bracket 31, a focus drive mechanism 32, a circuit board assembly 33, and a guide rod 34. In one embodiment, the focus drive mechanism 32 may include a focus coil 321 and a focus magnetic member 322. The circuit board assembly 33 may include a focus circuit board 331, a focus drive chip 332, a focus sensor 333, and a focus reinforcement 334. In other embodiments, the circuit board assembly 33 may not include the focus sensor 333 and / or the focus reinforcement 334.

[0117] FIG. 7 is a schematic structural diagram of the base 11 shown in FIG. 6 in some embodiments.

[0118] As shown in FIG7 , the base 11 may include a bottom plate 111. The bottom plate 111 may be substantially square. The bottom plate 111 may include a first side region 1111, a second side region 1112, a third side region 1113, and a fourth side region 1114 connected end to end. The first side region 1111 and the third side region 1113 may be arranged opposite each other, and the fourth side region 1114 and the second side region 1112 may be arranged opposite each other. For example, the first side region 1111 and the second side region 1112 may be arranged perpendicular to each other, the third side region 1113 may be parallel to the first side region 1111, and the fourth side region 1114 may be parallel to the second side region 1112.

[0119] For example, the bottom plate 111 may have a first surface 111a, a second surface 111b, and a third surface 111c. The first surface 111a and the second surface 111b are disposed opposite each other in a third direction Z. The third surface 111c is connected between the first surface 111a and the second surface 111b. A first through hole 1115 may be provided in the bottom plate 111. The first through hole 1115 may pass through the first surface 111a and the second surface 111b. The first side region 1111, the second side region 1112, the third side region 1113, and the fourth side region 1114 surround the first through hole 1115.

[0120] Exemplarily, the bottom plate 111 may be further provided with a plurality of mounting holes 1116 , where there are four mounting holes 1116 , which are respectively located at the four corners of the bottom plate 111 , and the mounting holes 1116 pass through the first surface 111a and the second surface 111b of the bottom plate 111 .

[0121] Exemplarily, a plurality of mounting blocks 112 may be provided on the base plate 111, and the plurality of mounting blocks 112 may be located in a space surrounded by four mounting holes 1116. The plurality of mounting blocks 112 may include a first mounting block 1121, a second mounting block 1122, and a third mounting block 1123. The first mounting block 1121 protrudes relative to the base plate 111 and is located at the connection between the first side area 1111 and the second side area 1112. The second mounting block 1122 protrudes relative to the base plate 111 and is located at the connection between the second side area 1112 and the third side area 1113. The third mounting block 1123 protrudes relative to the base plate 111 and is located at the connection between the fourth side area 1114 and the first side area 1111. In some embodiments, a fourth mounting block may be provided on the bottom plate 111. The fourth mounting block may protrude relative to the bottom plate 111 and be located at the connection between the third side area 1113 and the fourth side area 1114. Alternatively, the base 11 may include a first mounting block 1121, a second mounting block 1122 and a fourth mounting block, but not the third mounting block 1123, etc. This application does not limit this.

[0122] Illustratively, mounting block 112 may be provided with a groove 113. Groove 113 may be formed by a side of mounting block 112 facing away from first surface 111a and recessed into the interior of mounting block 112. Groove 113 extends parallel to the XY plane. Illustratively, first, second, and third mounting blocks 1121, 1122, and 1123 may each be provided with a first groove 1131, a second groove 1132, and a third groove 1133, respectively, for receiving and mounting other structural components.

[0123] For example, a block group 114 may be further provided on the bottom plate 111. The block group 114 may include two block groups that are spaced apart and both block groups protrude relative to the bottom plate 111. The number of block groups 114 may be three. The three block groups 114 may include a first block group 1141, a second block group 1142, and a third block group 1143. The first block group 1141 may be located in the first side area 1111. The two blocks in the first block group 1141 may be spaced apart along the second direction X, and the first block group 1141 may be located in the first mounting block 112. 1 and the third mounting block 1123; a second block group 1142 can be located in the second side region 1112, with the two blocks within the second block group 1142 spaced apart along the first direction Y, and the second block group 1142 is located between the first mounting block 1121 and the second mounting block 1122; a third block group 1143 can be located in the third side region 1113, with the two blocks within the third block group 1143 spaced apart along the second direction X, and the third block group 1143 is located closer to the second mounting block 1122 than to the fourth side region 1114. The number, spacing, size, and shape of the blocks within each block group 114 can be the same or completely different, and this application is not limited thereto. In other embodiments, the third block group 1143 can be located closer to the fourth side region 1114 than to the second side region 1112.

[0124] Fig. 8 is a partially exploded schematic diagram of the base 11 shown in Fig. 7 in some embodiments. Fig. 9 is a partially cross-sectional schematic diagram of the base 11 shown in Fig. 7 taken along CC in some embodiments.

[0125] As shown in Figures 8 and 9, the base 11 may further include a plurality of conductive members 115, which may include a first conductive portion 1151, a second conductive portion 1152, and an extension portion 1153. The extension direction of the first conductive portion 1151 may be parallel to the XY plane, the second conductive portion 1152 may be bent and connected to the first conductive portion 1151 and extend along a third direction Z, and the extension portion 1153 may also be bent and connected to the first conductive portion 1151 and located on the same side of the first conductive portion 1151 and the second conductive portion 1152. Exemplarily, the extension portion 1153 may be provided with a through-hole 1154, which may penetrate the extension portion 1153 in the third direction Z. Exemplarily, the extension portion 1153 may be annular.

[0126] In some embodiments, multiple conductive members 115 may be embedded in the base plate 111 at intervals. For example, there may be four conductive members 115 , wherein the four extensions 1153 are respectively provided corresponding to the four mounting holes 1116 , the mounting holes 1116 and the through-holes 1154 at least partially overlap, and the through-holes 1154 may be exposed relative to the mounting holes 1116 .

[0127] The extension portion 1153 and the first conductive portion 1151 can be used to electrically connect other structural components in the motor 1 with the second conductive portion 1152. The end of the second conductive portion 1152 can also be exposed relative to the second surface 111b and / or the third surface 111c for electrical connection to the module circuit board 3 (as shown in Figure 5). In other words, the conductive member 115 can be used as an electrical connection transmission channel between the structural components in the motor 1 and the module circuit board 3. In some embodiments, the number of conductive members 115 can also be seven, fifteen, or twenty, etc., and multiple conductive members 115 can be arranged in the first side area 1111, the second side area 1112, and the third side area 1113. The conductive member 115 can also include the first conductive portion 1151 and the second conductive portion 1152, but does not include the extension portion 1153. This application is not limited to this.

[0128] For example, the base 11 may further include a first metal member 116, which may include a reinforcement portion 1161 and a support portion 1162. The reinforcement portion 1161 may be frame-shaped and may include a first edge 1161a, a second edge 1161b, a third edge 1161c, and a fourth edge 1161d. The number of support portions 1162 may be three, including a first support portion 1163, a second support portion 1164, and a third support portion 1165. The first support portion 1163 is located at the connection between the first edge 1161a and the second edge 1161b, the second support portion 1164 is located at the connection between the second edge 1161b and the third edge 1161c, and the third support portion 1165 is located at the connection between the fourth edge 1161d and the first edge 1161a. In some embodiments, the reinforcement portion 1161 and the support portion 1162 may be an integrally formed structure.

[0129] Exemplarily, the support portion 1162 may include a first part 1162a and a second part 1162b, the second part 1162b is connected between the first part 1162a and the reinforcement portion 1161, the second part 1162b is vertically arranged relative to the reinforcement portion 1161, the first part 1162a is bent relative to the second part 1162b, and is spaced apart from the reinforcement portion 1161.

[0130] In some embodiments, the first metal member 116 is installed in the bottom plate 111. The first metal member 116 can improve the overall strength of the base 11 to prevent damage to the base 11, which is beneficial to improving the reliability of the base 11. For example, the first metal member 116 can be made of steel sheet. Exemplarily, the first edge 1161a can be embedded in the first side area 1111, the second edge 1161b can be embedded in the second side area 1112, the third edge 1161c can be embedded in the third side area 1113, and the fourth edge 1161d can be embedded in the fourth side area 1114. The first support portion 1163 can be embedded in the first mounting block 1121, the second support portion 1164 can be embedded in the second mounting block 1122, and the third support portion 1165 can be embedded in the third mounting block 1123. For example, the reinforcing portion 1161 can be embedded in the bottom plate 111 and located on the side of the supporting portion 1162 away from the groove 113, wherein the second portion 1162b can be embedded in the corresponding mounting block 112, and the first portion 1162a can be exposed relative to the corresponding groove 113. In other embodiments, the reinforcing portion 1161 can also be fixed to the side of the second surface 111b away from the first surface 111a by gluing or other means, which is not limited in this application.

[0131] For example, the first conductive portion 1151 can be located in the area between the first portion 1162a and the reinforcement portion 1161, and spaced apart from both the support portion 1162 and the reinforcement portion 1161. The second conductive portion 1152 is also spaced apart from the edge of the reinforcement portion 1161 and located on the side of the reinforcement portion 1161 away from the first through-hole 1115. In this case, the conductive member 115 and the first metal member 116 can form a three-layer structure. For example, the first layer is the first portion 1162a, which is used to enhance the structural strength of the groove 113. The second layer is the first conductive portion 1151, which serves as an electrical transmission channel within the base 11. The third layer is the reinforcement portion 1161, which is used to enhance the structural strength of the bottom plate 111. By locating the first conductive portion 1151 in the area between the first portion 1162a and the reinforcement portion 1161, the space within the bottom plate 111 can be effectively and fully utilized, which facilitates the miniaturization of the motor 1. In addition, by arranging the conductive member 115 and the first metal member 116 to be spaced apart, interference with the electrical transmission process of the conductive member 115 when the first metal member 116 contacts the conductive member 115 can be avoided, thereby ensuring the reliability of the motor 1 while achieving miniaturization.

[0132] Fig. 10 is a partially exploded schematic diagram of the motor 1 shown in Fig. 6 in some embodiments. Fig. 11 is a first schematic diagram of a partial structure of the motor 1 shown in Fig. 10 .

[0133] As shown in Figures 10 and 11 , in some embodiments, the first anti-shake coil 221 is mounted on the first side region 1111 to be fixed to the base 11. The second anti-shake coil 223 is mounted on the second side region 1112 to be fixed to the base 11. The compensation coil 231 is mounted on the third side region 1113 to be fixed to the base 11.

[0134] In some embodiments, the first anti-shake coil 221 can be arranged around the first block group 1141, the second anti-shake coil 223 can be arranged around the second block group 1142, and the compensation coil 231 can be arranged around the third block group 1143. The block group 114 can be used to limit the first anti-shake coil 221, the second anti-shake coil 223 and the compensation coil 231.

[0135] For example, the first anti-shake drive mechanism 22a may further include a first position sensor 225, which is fixed to the first side region 1111 and located inside the first anti-shake coil 221. The first position sensor 225 is used to detect the position and may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0136] For example, the second anti-shake drive mechanism 22b may further include a second position sensor 226, which is fixed to the second side region 1112 and located inside the second anti-shake coil 223. The second position sensor 226 is used to detect the position and may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0137] Exemplarily, the compensation mechanism 23 may further include a third position sensor 233, which is fixed to the third side region 1113 and located inside the compensation coil 231. The third position sensor 233 is used to detect the position, and the third position sensor 233 may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0138] As shown in Figures 10 and 11, in some embodiments, the four suspension wires 12 can be installed in a one-to-one correspondence in the four mounting holes 1116. For example, the four suspension wires 12 can include a first suspension wire 121, a second suspension wire 122, a third suspension wire 123, and a fourth suspension wire 124. The shapes and sizes of the four suspension wires 12 can be the same or different, which is not limited in this application.

[0139] Illustratively, the first suspension wire 121 may include a first fixed end 12a and a second fixed end 12b disposed opposite each other. The first suspension wire 121 may be disposed vertically relative to the base 11, and the first fixed end 12a may extend into the through-hole 1154 (as shown in FIG8 ) and the mounting hole 1116 and be snap-fitted into the mounting hole 1116, thereby achieving a fixed connection between the first suspension wire 121 and the base 11. Illustratively, the first fixed end 12a may be fixed in the mounting hole 1116 by gluing, welding, or the like.

[0140] It is understandable that the connection method between the second suspension wire 122, the third suspension wire 123, and the fourth suspension wire 124 and the base 11 can refer to the connection method between the first suspension wire 121 and the base 11. This application does not limit this in detail.

[0141] Exemplarily, the first fixed end 12a of the first suspension wire 121 can be located at the connection between the first side area 1111 and the second side area 1112, the first fixed end 12a of the second suspension wire 122 can be located at the connection between the second side area 1112 and the third side area 1113, the first fixed end 12a of the third suspension wire 123 can be located at the connection between the third side area 1113 and the fourth side area 1114, and the first fixed end 12a of the fourth suspension wire 124 can be located at the connection between the fourth side area 1114 and the first side area 1111.

[0142] For example, the ball group 24 may include a first ball group 241, a second ball group 242, and a third ball group 243, wherein each ball group 24 may include multiple balls, and the number of balls may be twelve, sixteen, or twenty, etc., which is not limited in this application. The shape, number, and size of the balls in each ball group 24 may be the same or different. In the embodiment of the present application, the shape and size of each ball in the ball group 24 are the same, and the number of balls in the first ball group 241, the second ball group 242, and the third ball group 243 are the same are used as an example for description. In other embodiments, the ball group 24 may also include a fourth ball group, etc., or the number of balls in the ball group 24 may also be one, which is not limited in this application.

[0143] For example, the first ball group 241 may be disposed in the first groove 1131. The balls of the first ball group 241 may roll in the first groove 1131. Part of the balls of the first ball group 241 may be located in the first groove 1131, and part may be located outside the first groove 1131.

[0144] For example, the second ball group 242 may be disposed in the second groove 1132. The balls of the second ball group 242 may roll in the second groove 1132. Part of the balls of the second ball group 242 may be located in the second groove 1132, and part of the balls may be located outside the second groove 1132.

[0145] For example, the third ball group 243 may be disposed in the third groove 1133. The balls of the third ball group 243 may roll in the third groove 1133. Part of the balls of the third ball group 243 may be located in the third groove 1133, and part of the balls may be located outside the third groove 1133.

[0146] For example, the ball group 24 may be located within the corresponding groove 113 and contact the first portion 1162a of the corresponding support portion 1162, thereby rolling and connecting to the first portion 1162a. For example, the first ball group 241 may also be located within the first groove 1131 and contact the first portion 1162a of the first support portion 1163, thereby rolling and connecting to the first portion 1162a of the first support portion 1163. The second ball group 242 may be located within the second groove 1132 and contact the first portion 1162a of the second support portion 1164, thereby rolling and connecting to the first portion 1162a of the second support portion 1164. The third ball group 243 may be located within the third groove 1133 and contact the first portion 1162a of the third support portion 1165, thereby rolling and connecting to the first portion 1162a of the third support portion 1165. Among them, the first support part 1163, the second support part 1164 and the third support part 1165 are all made of steel sheets. By setting the first support part 1163, the second support part 1164 and the third support part 1165, they are respectively embedded in the first mounting block 1121, the second mounting block 1122 and the third mounting block 1123, and can contact the corresponding ball group 24. The support part 1162 can enhance the structural strength of the mounting block 112, avoid the mounting block 112 from being compressed and deformed, and at the same time reduce the friction resistance of the ball group 24 during the rolling process.

[0147] Fig. 12 is a partially exploded schematic diagram of the anti-shake bracket 21 shown in Fig. 6 in some embodiments. Fig. 13 is a schematic structural diagram of the anti-shake bracket 21 shown in Fig. 12 from another angle.

[0148] As shown in Figures 12 and 13, the anti-shake bracket 21 may exemplarily include an anti-shake bracket body 211. The anti-shake bracket body 211 may be generally annular and may have a first side 211a, a second side 211b, and a connecting section 210 connected in sequence. The connecting section 210 may include a third side 211c and a fourth side 211d. The third side 211c may be connected between the second side 211b and the fourth side 211d. The first side 211a and the second side 211b are arranged at an angle, the first side 211a and the third side 211c are arranged opposite each other, and the fourth side 211d and the second side 211b are arranged opposite each other. Exemplarily, the first side 211a and the second side 211b may be perpendicular to each other, the third side 211c may be parallel to the first side 211a, and the fourth side 211d may be parallel to the second side 211b.

[0149] For example, the anti-shake bracket 21 may have a top surface 2111 and a bottom surface 2112 that are oppositely disposed in the third direction Z. A second through-hole 2113 may be defined within the anti-shake bracket 21. The second through-hole 2113 may penetrate the top surface 2111 and the bottom surface 2112. The second through-hole 2113 is located between the first side 211a and the third side 211c, and between the second side 211b and the fourth side 211d. In other words, the first side 211a, the second side 211b, the third side 211c, and the fourth side 211d surround the second through-hole 2113.

[0150] For example, the anti-shake bracket 21 may be provided with a plurality of fixing posts 212, which may be provided on the top surface 2111 and protrude relative to the top surface 2111. For example, the plurality of fixing posts 212 may be distributed on the first side 211a, the second side 211b, the third side 211c, and the fourth side 211d.

[0151] The anti-shake bracket 21 may be provided with a first mounting groove 2131, a second mounting groove 2132, and a third mounting groove 2133. The first mounting groove 2131 is located on the first side 211a, the second mounting groove 2132 is located on the second side 211b, and the third mounting groove 2133 is located on the third side 211c. The first, second, and third mounting grooves 2131, 2132, 2133 are located on the same side of the anti-shake bracket 21. For example, the first mounting groove 2131 may be formed by a recessed portion of the bottom surface 2112 toward the first side 211a. The sizes of the first, second, and third mounting grooves 2131, 2132, and 2133 may be the same or different, and this is not limited in this application. In some embodiments, the third mounting groove 2133 may be located on the fourth side 211d or elsewhere, and this is not limited in this application.

[0152] Illustratively, a fourth mounting groove 2134 may be further defined in the anti-shake bracket 21 . The fourth mounting groove 2134 is located at the fourth side portion 211 d , and an opening of the fourth mounting groove 2134 faces the second through hole 2113 .

[0153] Exemplarily, the fourth side portion 211d further comprises a slide groove 214. The number of slide grooves 214 may be two. The two slide grooves 214 include a first slide groove 2141 and a second slide groove 2142. The first slide groove 2141 and the second slide groove 2142 are located on either side of the fourth mounting groove 2134. The extension direction of the slide groove 214 may be parallel to the third direction Z.

[0154] For example, the anti-shake bracket 21 may further include wiring 215, which may be embedded within the anti-shake bracket body 211 to form multiple transmission channels for signal transmission. The anti-shake bracket body 211 may comprise a first side 211a, a second side 211b, a third side 211c, and a fourth side 211d. The number of wiring 215 may be two, four, six, or another number. Multiple wiring 215 may be arranged within the first side 211a, the second side 211b, the third side 211c, and the fourth side 211d.

[0155] In some embodiments, the end of the trace 215 can be exposed relative to the anti-shake bracket 21 for electrical connection to structural components within the camera module 100. For example, the end of the trace 215 can be exposed relative to the top surface 2111, or the end of the trace 215 can be exposed relative to the fourth side 211d. In other embodiments, the area where the trace 215 is exposed relative to the anti-shake bracket 21 can be set as needed, and this application is not limited to this.

[0156] Exemplarily, the anti-shake bracket 21 further includes a metal insert 216, and the metal insert 216 can be generally in a "C" shape. The metal insert 216 can include a first insert 2161a, a first plate 2161b, a second insert 2162a, a second plate 2162b, a third insert 2163a, and a third plate 2163b. The first plate 2161b is connected between the first insert 2161a and the second insert 2162a and protrudes relative to the first insert 2161a and the second insert 2162a; the second plate 2162b is connected between the second insert 2162a and the third insert 2163a and protrudes relative to the second insert 2162a and the third insert 2163a; one end of the third plate 2163b is connected to the third insert 2163a and protrudes relative to the third insert 2163a. Exemplarily, the first plate 2161b and the second plate 2162b can be arranged at an angle, the first plate 2161b and the third plate 2163b can be arranged opposite to each other, the first insert 2161a and the second insert 2162a can be perpendicular or substantially perpendicular to each other, and the first insert 2161a and the third insert 2163a can be parallel or substantially parallel to each other.

[0157] It can be understood that the first insert 2161a, the first plate 2161b, the second insert 2162a, the second plate 2162b, the third insert 2163a, and the third plate 2163b of the metal insert 216 can be an integrally formed structure. Exemplarily, the first insert 2161a, the first plate 2161b, the second insert 2162a, the second plate 2162b, the third insert 2163a, and the third plate 2163b of the metal insert 216 can be formed by bending or stamping an integral metal piece. In this way, the processing steps of the metal insert 216 can be reduced, thereby reducing the input of processing costs. In other embodiments, the first insert 2161a, the first plate 2161b, the second insert 2162a, the second plate 2162b, the third insert 2163a, and the third plate 2163b can also be connected into a whole by means of welding, bonding, buckling, etc. Specifically, the present application does not make a limitation.

[0158] For example, the metal insert 216 can be embedded in the anti-shake bracket body 211, the first insert 2161a is embedded in the connection between the fourth side 211d and the first side 211a, the first plate 2161b is embedded in the first side 211a, the second insert 2162a is embedded in the connection between the first side 211a and the second side 211b, the second plate 2162b is embedded in the second side 211b, and the third insert 2163a is embedded in the connection between the second side 211b and the third side. At the connection between the two parts 211c, the third plate 2163b is embedded in the third side portion 211c, the first mounting groove 2131 is located in the area surrounded by the first insert 2161a, the first plate 2161b and the second insert 2162a; the second mounting groove 2132 is located in the area surrounded by the second insert 2162a, the second plate 2162b and the third insert 2163a; the third mounting groove 2133 is located in the area surrounded by the third insert 2163a and the third plate 2163b.

[0159] In this embodiment, the metal insert 216 is embedded in the anti-shake bracket body 211 and can be formed into an integrally formed structural component with the anti-shake bracket body 211 through methods such as insert molding. In this case, the metal insert 216 is embedded in the anti-shake bracket body 211. In this way, the metal insert 216 can improve the overall strength of the anti-shake bracket 21. In other embodiments, at least a portion of the first plate 2161b can also be fixed to the bottom wall of the first mounting groove 2131 by bonding or other methods. At least a portion of the second plate 2162b can also be fixed to the bottom wall of the second mounting groove 2132 by bonding or other methods. At least a portion of the third plate 2163b can also be fixed to the bottom wall of the third mounting groove 2133 by bonding or other methods.

[0160] FIG14 is a second schematic diagram of a partial structure of the motor 1 shown in FIG6 in some embodiments.

[0161] As shown in FIG14 , for example, the first anti-shake magnetic component 222 is mounted in the first mounting slot 2131, the second anti-shake magnetic component 224 is mounted in the second mounting slot 2132, and the compensating magnetic component 232 is mounted in the third mounting slot 2133. In this case, the compensating magnetic component 232, the first anti-shake magnetic component 222, and the second anti-shake magnetic component 224 can be arranged in an L-shape. The first and second anti-shake magnetic components 222, 224 are arranged on both sides of the first and second sides 211a, 211b of the anti-shake bracket 21. The compensating magnetic component 232 is arranged on the third side 211c of the anti-shake bracket 21. No structural components are required on the fourth side 211d of the anti-shake bracket 21. This allows full utilization of three sides of the anti-shake bracket 21, while minimizing the volume of the remaining side, thereby facilitating the overall miniaturization of the motor 1.

[0162] In some embodiments, the first anti-shake magnetic component 222 has a first axis 21a, which may pass through the center of the first anti-shake magnetic component 222 and be parallel to the first direction Y. The second anti-shake magnetic component 224 may have a second axis 21b, which may pass through the center of the second anti-shake magnetic component 224 and be parallel to the second direction X. The center of the compensating magnetic component 232 is offset from both the first axis 21a and the second axis 21b. In this case, the first axis 21a does not pass through the center of the compensating magnetic component 232, and a distance exists between the center of the compensating magnetic component 232 and the first axis 21a in the first direction Y. The second axis 21b does not pass through the center of the compensating magnetic component 232, and a distance exists between the center of the compensating magnetic component 232 and the second axis 21b in the second direction X. For example, the compensating magnetic component 232 may be located on the side of the first axis 21a closer to the second anti-shake magnetic component 224. In other embodiments, the compensating magnetic component 232 may also be located on the side of the first axis 21a facing away from the second anti-shake magnetic component 224.

[0163] In some examples, the compensation magnetic member 232 can be staggered with both the first axis 21a and the second axis 21b. In this way, on the one hand, the center of the compensation magnetic member 232 can be staggered with both the first axis 21a and the second axis 21b, and on the other hand, the torque of the compensation magnetic member 232 can be increased.

[0164] Exemplarily, the first anti-shake magnetic component 222 may include one or more magnets, and the implementation structure of the first anti-shake magnetic component 222 may be various. For example, in some embodiments, the first anti-shake magnetic component 222 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the first direction Y and have opposite polarity directions. In other embodiments, the first anti-shake magnetic component 222 is a Halbach magnet array. For example, the first anti-shake magnetic component 222 may include at least three magnets, of which the polarity directions of the two adjacent magnets 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 the other. In other embodiments, the first anti-shake magnetic component 222 may adopt a single magnet solution, for example, consisting of a single magnet, the magnet including two parts with opposite polarity directions. The magnet may be manufactured using a bipolar magnetization process. In the embodiment of the present application, the first anti-shake magnetic component 222 is described as a Halbach magnet array as an example, but the present application does not limit this.

[0165] Exemplarily, the second anti-shake magnetic component 224 may include one or more magnets, and the implementation structure of the second anti-shake magnetic component 224 may be multiple. For example, in some embodiments, the second anti-shake magnetic component 224 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the second direction X, and the polarity directions are opposite. In other embodiments, the second anti-shake magnetic component 224 is a Halbach magnet array. In other embodiments, the second anti-shake magnetic component 224 may adopt a single magnet solution, for example, consisting of a magnet, the magnet includes two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process. In the embodiment of the present application, the second anti-shake magnetic component 224 is a Halbach magnet array as an example for introduction, and the present application is not limited to this.

[0166] Exemplarily, the compensation magnetic member 232 may include one or more magnets, and the implementation structure of the compensation magnetic member 232 may be various. For example, in some embodiments, the compensation magnetic member 232 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the first direction Y, and the polarity directions are opposite. In other embodiments, the compensation magnetic member 232 is a Halbach magnet array. In other embodiments, the compensation magnetic member 232 may adopt a single magnet solution, for example, consisting of a magnet, and the polarity direction of the magnet is parallel to the third direction Z. In the embodiment of the present application, the compensation magnetic member 232 is introduced as a single magnet as an example, and the present application is not limited to this. In some examples, the length of the compensation magnetic member 232 may be less than the length of the first anti-shake magnetic member 222 and the length of the second anti-shake magnetic member 224, which is beneficial to reducing the space occupied by the compensation magnetic member 232 in the anti-shake bracket 21, which is beneficial to reducing the size of the anti-shake bracket 21 and realizing the miniaturization of the motor 1.

[0167] Figure 15 is a partially exploded schematic diagram of the motor 1 shown in Figure 6 in some embodiments. Figure 16 is a third schematic diagram of the partial structure of the motor 1 shown in Figure 6 in some embodiments. Figure 17 is a partial cross-sectional schematic diagram of the motor 1 shown in Figure 16 taken along line DD in some embodiments.

[0168] As shown in Figures 15, 16, and 17, the anti-shake bracket 21 can be movably connected to the base 11 via a first ball group 241, a second ball group 242, and a third ball group 243. The anti-shake bracket 21 is movably connected to the base 11 through the rolling connection between the ball group 24 and the base 11. In this embodiment, the ball group 24 provides support, ensuring sufficient support force while reducing friction between the balls and the anti-shake bracket 21, thereby improving the smoothness of the movement of the anti-shake bracket 21 in connection with the base 11. Furthermore, the ball group 24 provides multi-point support for the anti-shake bracket 21, which helps disperse stress and prevents deformation of the balls due to excessive force concentration in a single direction during collisions. This improves the reliability of the ball group 24's support of the anti-shake bracket 21 and other structural components. In other embodiments, the motor 1 may not include the ball group 24, but instead include a guide shaft, through which the anti-shake bracket 21 can be movably connected to the base 11. This is not a limitation of this application. At this time, the first ball group 241 is connected to the connection between the first side 211a and the second side 211b, the second ball group 242 is connected to the connection between the second side 211b and the third side 211c, and the third ball group 243 is connected to the connection between the fourth side 211d and the first side 211a. The three ball groups 24 can form a three-point support structure, which ensures the bearing capacity of the ball group 24 on the anti-shake bracket 21 while helping to reduce the number of ball groups 24 and reduce the manufacturing cost of the motor 1.

[0169] For example, the first ball group 241 and the third ball group 243 can be located on the same side of the second axis 21b, and the second ball group 242 is located on the other side of the second axis 21b. The two opposite sides of the anti-shake bracket 21 can be supported by the ball group 24, which can prevent the anti-shake bracket 21 from tilting due to unilateral force during movement.

[0170] For example, the first ball group 241 and the third ball group 243 are respectively located on opposite sides of the first axis 21a to prevent the anti-shake bracket 21 from tilting toward one side when the three ball groups 24 are concentrated on the same side of the first axis 21a, thereby affecting the smoothness and reliability of the movement process of the anti-shake bracket 21.

[0171] In some embodiments, the first side 211a corresponds to the first side region 1111, the second side 211b corresponds to the second side region 1112, the third side 211c corresponds to the third side region 1113, and the fourth side 211d corresponds to the fourth side region 1114. For example, the first through-hole 1115 and the second through-hole 2113 at least partially overlap. In other words, the anti-shake bracket 21 and the base 11 can be considered to be coaxially nested, which helps to improve the compactness of the arrangement of the internal components of the motor 1, improve the utilization of the space within the motor 1, and facilitate the miniaturization of the motor 1. For example, the center of the base 11 and the center of the anti-shake bracket 21 can both be located on the optical axis of the lens 2 (as shown in FIG. 5 ).

[0172] Exemplarily, the first anti-shake magnetic component 222 is fixed to the anti-shake bracket 21, and the first anti-shake coil 221 is disposed facing the first anti-shake magnetic component 222, for driving the anti-shake bracket 21 to move relative to the base 11 in a first direction Y. The first anti-shake magnetic component 222 and the first anti-shake coil 221 are arranged in a third direction Z. The first anti-shake coil 221 is disposed facing the first anti-shake magnetic component 222, meaning that the winding plane of the first anti-shake coil 221 faces the first anti-shake magnetic component 222. For example, the winding plane of the first anti-shake coil 221 can be disposed perpendicular to the third direction Z. In this case, the first anti-shake coil 221 can be disposed horizontally, which facilitates reducing the size of the motor 1 in the third direction Z and achieving miniaturization of the motor 1. Exemplarily, the first position sensor 225 (as shown in FIG. 17 ) can be used to detect changes in the first magnetic field of the first anti-shake magnetic component 222 when the anti-shake bracket 21 moves in the first direction Y, thereby detecting changes in the position of the anti-shake bracket 21 in the first direction Y.

[0173] In addition, by arranging the first anti-shake coil 221 and the first anti-shake magnetic component 222 in the third direction Z, during the movement of the anti-shake bracket 21 relative to the base 11, the movement direction of the anti-shake bracket 21 can be perpendicular to the magnetic gap between the first anti-shake magnetic component 222 and the first anti-shake coil 221. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket 21, so it can avoid the problem of rapid decrease in driving force due to the increase in magnetic gap, and can ensure the stability of the driving force while having a large anti-shake driving force, which is conducive to the anti-shake design with a large stroke.

[0174] Fig. 18 is a partial cross-sectional schematic diagram of the motor 1 shown in Fig. 16 taken along line EE in some embodiments. Fig. 19 is a partial cross-sectional schematic diagram of the motor 1 shown in Fig. 16 taken along line FF in some embodiments.

[0175] As shown in Figure 18, illustratively, a second anti-shake magnetic element 224 is fixed to the anti-shake bracket 21, and a second anti-shake coil 223 is disposed facing the second anti-shake magnetic element 224, configured to drive the anti-shake bracket 21 to move relative to the base 11 in the second direction X. The second anti-shake magnetic element 224 and the second anti-shake coil 223 are arranged in the third direction Z. The second anti-shake coil 223 is disposed facing the second anti-shake magnetic element 224, meaning that the winding plane of the second anti-shake coil 223 faces the second anti-shake magnetic element 224. For example, the winding plane of the second anti-shake coil 223 can be disposed perpendicular to the third direction Z. In this case, the second anti-shake coil 223 can be disposed horizontally, which helps reduce the size of the motor 1 in the third direction Z and achieve miniaturization of the motor 1. Exemplarily, the second position sensor 226 can be configured to detect changes in the second magnetic field of the second anti-shake magnetic element 224 when the anti-shake bracket 21 moves in the second direction X, thereby detecting changes in the position of the anti-shake bracket 21 in the second direction X.

[0176] In addition, by arranging the second anti-shake coil 223 and the second anti-shake magnetic component 224 in the third direction Z, during the movement of the anti-shake bracket 21 relative to the base 11, the movement direction of the anti-shake bracket 21 can be perpendicular to the magnetic gap between the second anti-shake magnetic component 224 and the second anti-shake coil 223. The above-mentioned magnetic gap is not affected by the movement of the anti-shake bracket 21, so it can avoid the problem of rapid decrease in driving force due to the increase in magnetic gap, and can ensure the stability of the driving force while having a large anti-shake driving force, which is conducive to the anti-shake design with a large stroke.

[0177] As shown in FIG19 , for example, the compensation magnetic member 232 is fixed to the anti-shake bracket 21, and the compensation coil 231 is arranged facing the compensation magnetic member 232. The compensation coil 231 being arranged facing the compensation magnetic member 232 means that the winding plane of the compensation coil 231 faces the compensation magnetic member 232. For example, the winding plane of the compensation coil 231 can be arranged perpendicular to the third direction Z. In this case, the compensation coil 231 can be arranged horizontally, which helps reduce the size of the motor 1 in the third direction Z and achieves miniaturization of the motor 1.

[0178] By providing the compensation mechanism 23, it is possible to solve the problem that during the movement of the anti-shake bracket 21 relative to the base 11, due to the mechanical structure and / or assembly process of the motor 1 itself, the resultant torque applied to the anti-shake bracket 21 is not zero, causing deflection in the XY plane during the translation along the first direction Y or the second direction X, thereby causing the anti-shake bracket 21 to be displaced in a direction other than the movement direction relative to the base 11. This is conducive to improving the reliability and control accuracy of the motor 1.

[0179] The third position sensor 233 can be used to detect a change in the third magnetic field of the compensating magnetic element 232 when the anti-shake bracket 21 moves in the first direction Y, and to obtain the deflection of the anti-shake bracket 21 based on the third magnetic field change and the first magnetic field change. For example, when the anti-shake bracket 21 moves in the first direction Y, the first position sensor 225 can detect the change in the first magnetic field of the first anti-shake magnetic element 222, and the third position sensor 233 can detect the change in the third magnetic field of the compensating magnetic element 232. If the anti-shake bracket 21 deflects, the displacements of opposite sides of the anti-shake bracket 21 in the first direction Y will differ. In this case, the change in the first magnetic field will be unequal to the change in the second magnetic field. The third position sensor 233 can obtain the deflection of the anti-shake bracket 21 based on the difference between the change in the first magnetic field and the change in the third magnetic field.

[0180] For example, when the anti-shake bracket 21 moves along the second direction X, the third position sensor 233 can detect the change in the fourth magnetic field of the compensation magnetic component 232. If the anti-shake bracket 21 is deflected, it will cause the anti-shake bracket 21 to be displaced in the first direction Y. At this time, the change in the fourth magnetic field will not be zero, and the deflection amount of the anti-shake bracket 21 can be obtained based on the change in the fourth magnetic field.

[0181] The following describes an example of the deflection of the anti-shake bracket 21 caused by the non-zero torque generated by the friction of the ball group 24 during movement of the anti-shake bracket 21 relative to the base 11 in the first direction Y and the second direction X. In other embodiments, the compensation mechanism 23 can also be used to address deflection of the anti-shake bracket 21 due to other factors, such as the misalignment of the motor 1's center of gravity or geometric center with the mechanical center between the X-axis and the Y-axis. This is not described in detail in this application. Furthermore, in this embodiment, the motor 1's center of gravity and geometric center coincide with the mechanical center between the X-axis and the Y-axis and lie on the optical axis.

[0182] Solution 1: Figure 20a is a schematic diagram of a working state of the compensation mechanism 23 provided in an embodiment of the present application. Figure 20b is a schematic diagram of another working state of the compensation mechanism 23 provided in an embodiment of the present application.

[0183] As shown in FIG20 a , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction X1 of the second direction (directed by the solid arrow in FIG20 a ):

[0184] The anti-shake bracket 21 will be affected by the first driving force F1 provided by the second anti-shake magnetic component 224, wherein the direction of the first driving force F1 is the positive direction X1 of the second direction, the lever arm of the first driving force F1 is zero, and the torque M1 generated by the first driving force F1 is 0. The first driving force F1 serves as a power source for driving the anti-shake bracket 21 to translate relative to the base 11 along the positive direction X1 of the second direction.

[0185] During movement, the anti-shake bracket 21 is also affected by the first friction force f1 between the anti-shake bracket 21 and the first ball group 241, the second friction force f2 between the anti-shake bracket 21 and the second ball group 242, and the third friction force f3 between the anti-shake bracket 21 and the third ball group 243. Among them, the lever arm of the first friction force f1, the lever arm of the second friction force f2, and the lever arm of the third friction force f3 are all L1, where L1 is the distance from the center of the first ball group 241 or the second ball group 242 or the third ball group 243 to the center of the anti-shake bracket 21 in the first direction Y. L1 is not zero. In Figure 20a, f13 represents the resultant force of the first friction force f1 and the third friction force f3. It can be understood that in the embodiment of the present application, the torque that causes the anti-shake bracket 21 to produce a counterclockwise rotation effect is defined as a positive torque, and vice versa as a negative torque. Therefore, the first rotational torque M2 generated by the ball group 24 on the anti-shake bracket 21 during the movement process is M2 = (f1×L1) + (f3×L1) - (f2×L1).

[0186] When M2≠0, it will drive the anti-shake bracket 21 to rotate in the XY plane, so that the anti-shake bracket 21 cannot drive the lens 2 to reach the preset position in the second direction X to realize the anti-shake function of the motor 1. It will also cause the lens 2 to produce additional displacement in the first direction Y, affecting the control accuracy and reliability of the motor 1.

[0187] It will be appreciated that in the embodiment of the present application, since the first anti-shake magnetic member 222 is provided on one side of the first edge 211a (as shown in FIG15 ), while the first anti-shake magnetic member 222 is not provided on the opposite side, the third edge 211c (as shown in FIG15 ), the anti-shake bracket 21 exerts different pressures on the base 11 on opposite sides of the first direction Y. Consequently, the frictional forces provided by the ball group 24 on the opposite sides of the anti-shake bracket 21 in the first direction Y also differ in magnitude. The sum of f1 and f3 is greater than f2, and the first torque M2 can be greater than 0. The first torque M2 is a positive torque, which is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11. In other embodiments, deflection of the anti-shake bracket 21 may also occur due to other reasons such as assembly errors of internal structural components within the motor 1, resulting in uneven force on opposite sides of the anti-shake bracket 21. This is not a limitation of the present application.

[0188] For example, in the embodiment of the present application, by providing a compensation mechanism 23 (as shown in FIG15 ), the anti-shake bracket 21 is also subjected to a first force f41 provided by the compensation magnetic member 232, which is used to generate a first compensation torque M3 to compensate for the first rotational torque M2, so that the resultant torque M4 applied to the anti-shake bracket 21 can be maintained at zero, ensuring that the anti-shake bracket 21 is subjected to the first driving force F1 to drive the lens 2 (as shown in FIG5 ) to translate in its preset direction (the second positive direction X1) without deflection. The moment arm of the first force f41 is L2, where L2 is the distance from the center of the compensation magnetic member 232 to the center of the anti-shake bracket 21 in the second direction X. L2 is not zero, and M3 = f41 × L2.

[0189] By adjusting the magnitude and direction of the current flowing through the compensation coil 231 of the compensation mechanism 23 (as shown in FIG15 ), the magnitude of the first compensation torque M3 is equal to the magnitude of the first rotational torque M2. The first compensation torque M3 is a negative torque, acting in the opposite direction of the first rotational torque M2. The first compensation torque M3 is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11, thereby balancing and offsetting any deflection of the anti-shake bracket 21 caused by the first rotational torque M2. This effectively improves the control accuracy and reliability of the motor 1. In this case, the direction of the first force f41 can be along the negative direction Y2 of the first direction, thereby enabling the anti-shake bracket 21 to rotate clockwise relative to the base 11 (M3 < 0). In other embodiments, the direction of the first force f41 can also be at an angle to the negative direction Y2 of the first direction. Alternatively, when the relative position of the compensation mechanism 23 and the center of the anti-shake bracket 21 changes, the direction of the first force f41 can be along the positive direction Y1 of the first direction, or along the second direction X. This can be adjusted as needed, and this application is not limited to this.

[0190] As shown in FIG20 b , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction Y1 of the first direction (directed by the solid arrow in FIG20 b ):

[0191] The anti-shake bracket 21 is acted upon by the second driving force F2 provided by the first anti-shake magnetic component 222. The direction of the second driving force F2 is the positive direction Y1 of the first direction, the moment arm of the second driving force F2 is zero, and the torque M5 generated by the second driving force F2 is 0. The second driving force F2 serves as a power source for driving the anti-shake bracket 21 to translate relative to the base 11 along the positive direction Y1 of the first direction.

[0192] During its motion, the anti-shake bracket 21 is also subject to a first friction force f1 between the anti-shake bracket 21 and the first ball group 241, a second friction force f2 between the anti-shake bracket 21 and the second ball group 242, and a third friction force f3 between the anti-shake bracket 21 and the third ball group 243. The moment arms of the first friction force f1, the second friction force f2, and the third friction force f3 are all L3, where L3 is the distance from the center of the first ball group 241 to the center of the anti-shake bracket 21 in the second direction X. L3 is non-zero. In Figure 20b, f12 represents the resultant force of the first friction force f1 and the second friction force f2. It will be appreciated that in this embodiment of the present application, the torque that produces a counterclockwise rotation effect on the anti-shake bracket 21 is defined as a positive torque, and the opposite as a negative torque. Therefore, the second rotational torque M6 generated by the ball group 24 during its motion, which is applied to the anti-shake bracket 21, is defined as (f3×L3)-(f1×L3)-(f2×L3).

[0193] When M6≠0, it will drive the anti-shake bracket 21 to rotate in the XY plane, so that the anti-shake bracket 21 cannot drive the lens 2 to reach the preset position in the first direction Y to realize the anti-shake function of the motor 1. It will also cause the lens 2 to produce additional displacement in the second direction X, affecting the control accuracy and reliability of the motor 1.

[0194] In the embodiment of the present application, since the second anti-shake magnetic member 224 is provided on the second side 211b (as shown in FIG15 ), while the second anti-shake magnetic member 224 is not provided on the opposite fourth side 211d (as shown in FIG15 ), the anti-shake bracket 21 exerts different pressures on the base 11 on opposite sides of the second direction X. This results in different frictional forces exerted by the ball group 24 on the opposite sides of the anti-shake bracket 21 in the second direction X. As a result, the sum of f1 and f2 is greater than f3, and the second torque M6 can be less than 0. The second torque M6 can be a negative torque, which is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11. In other embodiments, deflection of the anti-shake bracket 21 can also occur due to other reasons such as assembly errors of internal structural components within the motor 1, resulting in uneven force on the opposite sides of the anti-shake bracket 21. This is not limited to this aspect of the present application.

[0195] For example, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 is also subjected to the second force f42 provided by the compensation magnetic member 232, thereby generating a second compensation torque M7 to compensate for the second rotational torque M6. This allows the resultant torque M4 applied to the anti-shake bracket 21 to be restored to zero, ensuring that the anti-shake bracket 21 can drive the lens 2 to translate in its preset direction (first positive direction Y1) without deflection. The moment arm of the second force f42 is L2, where L2 is the distance from the center of the compensation magnetic member 232 to the center of the anti-shake bracket 21 in the second direction X. L2 is non-zero, and M7 = f42 × L2.

[0196] By adjusting the magnitude and direction of the current flowing through the compensation coil 231 within the compensation mechanism 23, the magnitude of the second compensation torque M7 is equal to the magnitude of the second rotational torque M6. The second compensation torque M7 is a positive torque, acting in the opposite direction of the second rotational torque M6. The second compensation torque M7 is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11, thereby balancing and eliminating any deflection of the anti-shake bracket 21 caused by the second rotational torque M6. This allows the anti-shake bracket 21 to maintain translational motion, thereby improving the control accuracy and reliability of the motor 1. In this case, the direction of the second force f42 can be along the positive direction Y1 of the first direction, enabling the anti-shake bracket 21 to rotate counterclockwise relative to the base 11 (M7 > 0). In other embodiments, the direction of the second force f42 can also be at an angle to the positive direction Y1 of the first direction. Alternatively, when the relative position of the compensation mechanism 23 and the center of the anti-shake bracket 21 changes, the direction of the second force f42 can also be along the second direction X. This can be adjusted as needed, and this application is not limited to this.

[0197] In the aforementioned embodiment, as shown in FIG15 , the compensation coil 231 is mounted in the third side region 1113 and is positioned near the second ball group 242. In this case, the compensation magnetic member can be located to the upper right of the center of the anti-shake bracket 21. In other embodiments, the compensation coil 231 can also be mounted in other locations. In this case, the relative position of the compensation magnetic member 232 relative to the center of the anti-shake bracket 21 will change accordingly, and the force direction and magnitude and direction of the force arm of the first force f41 and / or the second force f42 will also change. For example, the compensation coil 231 can also be mounted in the third side region 1113 and away from the second ball group 242, or the compensation coil 231 can also be mounted in the fourth side region 1114 and away from the third ball group 243, or the compensation coil 231 can also be mounted in the fourth side region 1114 and near the third ball group 243.

[0198] The following embodiments may include most of the technical solutions of the previous embodiments, mainly explaining the differences between the two, and most of the same contents between the two are not repeated.

[0199] Solution 2: Figure 21a is a schematic diagram of another compensation mechanism 23 provided in an embodiment of the present application in a working state. Figure 21b is a schematic diagram of another compensation mechanism 23 provided in an embodiment of the present application in a working state.

[0200] The difference between the motor 1 shown in Figures 21a and 21b and the motor 1 shown in Figures 20a and 20b is that in the motor 1 shown in Figures 21a and 21b, the compensation coil 231 can also be installed in the third side area 1113 and is set away from the second ball group 242, and the compensation magnetic part 232 is located in the upper left center of the anti-shake bracket 21.

[0201] As shown in FIG21a , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction X1 of the second direction (directed by the solid arrow in FIG21a ):

[0202] The anti-shake bracket 21 is acted upon by a first driving force F1 in the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 is 0. During the movement of the anti-shake bracket 21, the first torque M2 generated by the ball group 24 is M2 = (f1×L1)+(f3×L1)-(f2×L1), and M2>0.

[0203] In the embodiment of the present application, by providing a compensation mechanism 23, the anti-shake bracket 21 will also be affected by the first action force f41 provided by the compensation magnetic member 232, which is used to generate a first compensation torque M3 to compensate for the first rotational torque M2, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0204] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the magnitude of the first compensation torque M3 is equal to the magnitude of the first rotational torque M2. The first compensation torque M3 is a negative torque, acting in the opposite direction of the first rotational torque M2. The first compensation torque M3 is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11, thereby balancing and eliminating any deflection of the anti-shake bracket 21 caused by the first rotational torque M2, thereby improving the control accuracy and reliability of the motor 1. At this point, the moment arm of the first force f41 is L2, where L2 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the second direction X. M3 = f41 × L2. To enable clockwise rotation of the anti-shake bracket 21 relative to the base 11 (M3 < 0), the direction of the first force f41 can be along the positive direction Y1 of the first direction.

[0205] As shown in FIG21 b , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction Y1 of the first direction (directed by the solid arrow in FIG21 b ):

[0206] The anti-shake bracket 21 is acted upon by a second driving force F2 in the positive direction Y1 of the first direction. The torque M5 generated by the second driving force F2 is 0. The second rotational torque M6 generated by the ball group 24 during the movement of the anti-shake bracket 21 is (f3×L3)-(f1×L3)-(f2×L3), and M6<0.

[0207] For example, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 will also be affected by the second force f42 provided by the compensation magnetic member 232, generating a second compensation torque M7 to compensate for the second rotational torque M6, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0208] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the magnitude of the second compensation torque M7 is equal to the magnitude of the second rotational torque M6. The second compensation torque M7 is a positive torque, acting in the opposite direction of the second rotational torque M6. The second compensation torque M7 is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11, thereby balancing and eliminating any deflection of the anti-shake bracket 21 caused by the second rotational torque M6, thereby improving the control accuracy and reliability of the motor 1. At this point, the moment arm of the second force f42 is L2, where L2 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the second direction X. M7 = f42 × L2. To enable the anti-shake bracket 21 to rotate counterclockwise relative to the base 11 (M7 > 0), the direction of the second force f42 can be along the negative direction Y2 of the first direction. In other embodiments, the direction of the second force f42 can also be at an angle to the negative direction Y2 of the first direction.

[0209] Solution 3: Figure 22a is a schematic diagram of another compensation mechanism 23 provided in an embodiment of the present application in a working state. Figure 22b is a schematic diagram of another compensation mechanism 23 provided in an embodiment of the present application in a working state.

[0210] The difference between the motor 1 shown in Figures 22a and 22b and the motor 1 shown in Figures 20a and 20b is that in the motor 1 shown in Figures 22a and 22b, the compensation coil 231 can also be installed in the fourth side area 1114 and is set away from the third ball group 243, and the compensation magnetic part 232 is located in the upper left center of the anti-shake bracket 21.

[0211] As shown in FIG22a , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction X1 of the second direction (directed by the solid arrow in FIG22a ):

[0212] The anti-shake bracket 21 is acted upon by a first driving force F1 in the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 is 0. During the movement of the anti-shake bracket 21, the first torque M2 generated by the ball group 24 is M2 = (f1×L1)+(f3×L1)-(f2×L1), and M2>0.

[0213] In the embodiment of the present application, by providing a compensation mechanism 23, the anti-shake bracket 21 will also be affected by the third force f43 provided by the compensation magnetic member 232, which is used to generate a third compensation torque M8 to compensate the first rotational torque M2, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0214] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the magnitude of the third compensation torque M8 is equal to the magnitude of the first torque M2. The third compensation torque M8 is a negative torque, acting in the opposite direction of the first torque M2. The third compensation torque M8 is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11, thereby balancing and eliminating any deflection of the anti-shake bracket 21 caused by the first torque M2, thereby improving the control accuracy and reliability of the motor 1. At this point, the moment arm of the third force f43 is L4, where L4 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the first direction Y. M8 = f43 × L4. To enable clockwise rotation of the anti-shake bracket 21 relative to the base 11 (M8 < 0), the direction of the third force f43 can be along the negative second direction X2.

[0215] As shown in FIG22 b , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction Y1 of the first direction (directed by the solid arrow in FIG22 b ):

[0216] The anti-shake bracket 21 is acted upon by a second driving force F2 in the positive direction Y1 of the first direction. The torque M5 generated by the second driving force F2 is 0. The second rotational torque M6 generated by the ball group 24 during the movement of the anti-shake bracket 21 is (f3×L3)-(f1×L3)-(f2×L3), and M6<0.

[0217] For example, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 is also affected by the fourth force f44 provided by the compensation magnetic member 232, generating a fourth compensation torque M9 to compensate for the second rotational torque M6, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0218] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the fourth compensation torque M9 is equal in magnitude to the second torque M6. The fourth compensation torque M9 is a positive torque, acting in the opposite direction of the second torque M6. This fourth compensation torque M9 is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11, thereby balancing and eliminating any deflection that may result from the second torque M6. This improves the control accuracy and reliability of the motor 1. At this point, the moment arm of the fourth force f44 is L4, where L4 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the first direction Y. M9 = f44 × L4. To enable counterclockwise rotation of the anti-shake bracket 21 relative to the base 11 (M9 > 0), the direction of the fourth force f44 can be along the positive direction X1 of the second direction. In other embodiments, the direction of the fourth force f44 can also be at an angle to the positive direction X1 of the second direction.

[0219] Solution 4: Figure 23a is a schematic diagram of another working state of the compensation mechanism 23 provided in an embodiment of the present application. Figure 23b is a schematic diagram of another working state of the compensation mechanism 23 provided in an embodiment of the present application.

[0220] The difference between the motor 1 shown in Figures 23a and 23b and the motor 1 shown in Figures 20a and 20b is that in the motor 1 shown in Figures 23a and 23b, the compensation coil 231 can also be installed in the fourth side area 1114 and is arranged close to the third ball group 243, and the compensation magnetic part 232 is located at the lower left center of the anti-shake bracket 21.

[0221] As shown in FIG23a , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction X1 of the second direction (directed by the solid arrow in FIG23a ):

[0222] The anti-shake bracket 21 is acted upon by a first driving force F1 in the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 is 0. During the movement of the anti-shake bracket 21, the first torque M2 generated by the ball group 24 is M2 = (f1×L1)+(f3×L1)-(f2×L1), and M2>0.

[0223] In the embodiment of the present application, by providing a compensation mechanism 23, the anti-shake bracket 21 will also be affected by the third force f43 provided by the compensation magnetic member 232, which is used to generate a third compensation torque M8 to compensate the first rotational torque M2, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0224] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the magnitude of the third compensation torque M8 is equal to the magnitude of the first torque M2. The third compensation torque M8 is a negative torque, acting in the opposite direction of the first torque M2. This third compensation torque M8 is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11, thereby balancing and eliminating any deflection that may result from the first torque M2. This improves the control accuracy and reliability of the motor 1. At this point, the moment arm of the third force f43 is L4, where L4 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the first direction Y. M8 = f43 × L4. To enable clockwise rotation of the anti-shake bracket 21 relative to the base 11 (M8 < 0), the direction of the third force f43 can be along the positive second direction X1.

[0225] As shown in FIG23b , illustratively, during the movement of the anti-shake bracket 21 (shown in FIG15 ) relative to the base 11 (shown in FIG15 ) along the positive direction Y1 of the first direction (directed by the solid arrow in FIG23b ):

[0226] The anti-shake bracket 21 is acted upon by a second driving force F2 in the positive direction Y1 of the first direction. The torque M5 generated by the second driving force F2 is 0. The second rotational torque M6 generated by the ball group 24 during the movement of the anti-shake bracket 21 is (f3×L3)-(f1×L3)-(f2×L3), and M6<0.

[0227] For example, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 is also affected by the fourth force f44 provided by the compensation magnetic member 232, generating a fourth compensation torque M9 to compensate for the second rotational torque M6, so that the resultant torque M4 acting on the anti-shake bracket 21 can be maintained at zero.

[0228] By adjusting the magnitude and direction of the current flowing through the compensation coil 231, the fourth compensation torque M9 is equal in magnitude to the second torque M6. The fourth compensation torque M9 is a positive torque, acting in the opposite direction of the second torque M6. This fourth compensation torque M9 is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11, thereby balancing and eliminating any deflection that may result from the second torque M6 on the anti-shake bracket 21. This improves the control accuracy and reliability of the motor 1. At this point, the moment arm of the fourth force f44 is L4, where L4 is the distance from the center of the compensation magnetic element 232 to the center of the anti-shake bracket 21 in the first direction Y. M9 = f44 × L4. To enable counterclockwise rotation of the anti-shake bracket 21 relative to the base 11 (M9 > 0), the direction of the fourth force f44 can be along the negative direction X2 of the second direction. In other embodiments, the direction of the fourth force f44 can also be at an angle to the negative direction X2 of the second direction.

[0229] FIG24 is a schematic diagram of the assembly structure of the circuit board assembly 33 and the focusing coil 321 shown in FIG6 .

[0230] As shown in Figure 24, in some embodiments, the focus driver chip 332 and focus sensor 333 of the circuit board assembly 33 are both fixed to the focus circuit board 331 and electrically connected to the focus circuit board 331. The focus coil 321 is fixed to the focus circuit board 331 and electrically connected to the focus circuit board 331. It is understood that the input and output ends of the focus coil 321 can form a current loop with the focus driver chip 332 through the focus circuit board 331. In this case, the focus driver chip 332 can control the current flow through the focus coil 321 (e.g., whether current is flowing or the amount of current when it is flowing) through the focus circuit board 331. For example, the focus coil 321 can be arranged around the focus driver chip 332 and focus sensor 333. In this way, the focus driver chip 332 and focus sensor 333 can effectively utilize the space inside the focus coil 321, thereby significantly improving the space utilization of the motor 1.

[0231] Exemplarily, the focus sensor 333 is used to implement position detection, and the focus sensor 333 may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0232] For example, the focus reinforcement member 334 can be fixed to the side of the focus circuit board 331 facing away from the focus coil 321 to increase the structural strength of the circuit board assembly 33 and reduce the risk of deformation of the focus circuit board 331. It is understood that the position, size, and shape of the focus reinforcement member 334 are not specifically limited in this embodiment.

[0233] FIG25 is a fourth schematic diagram of the partial structure of the motor 1 shown in FIG6 in some embodiments.

[0234] As shown in Figures 24 and 25 , the circuit board assembly 33 is illustratively installed in the fourth mounting slot 2134 of the anti-shake bracket 21 to secure it to the anti-shake bracket 21. At this point, the focus coil 321 is secured to the anti-shake bracket 21 via the focus circuit board 331. It will be appreciated that at least a portion of the circuit board assembly 33 is located in the fourth mounting slot 2134, making the circuit board assembly 33 and the anti-shake bracket 21 compact, thereby improving space utilization.

[0235] Exemplarily, the focusing circuit board 331 and the focusing reinforcement member 334 of the circuit board assembly 33 can be fixed in the fourth mounting groove 2134 by means of adhesive or the like.

[0236] FIG. 26 is a schematic diagram of the structural decomposition of the focusing bracket 31 shown in FIG. 6 from another perspective.

[0237] As shown in FIG26 , in some embodiments, the focus bracket 31 can be generally frame-shaped and have a third through-hole 311. The focus bracket 31 is provided with a fifth mounting slot 312, a third slide slot 313, and a fourth slide slot 314. The openings of the fifth mounting slot 312, the third slide slot 313, and the fourth slide slot 314 can all be disposed away from the third through-hole 311.

[0238] For example, the third sliding groove 313 and the fourth sliding groove 314 may be located on both sides of the fifth mounting groove 312. The extending directions of the third sliding groove 313 and the fourth sliding groove 314 may be parallel to the third direction Z.

[0239] It is understandable that the third through hole 311 of the focus bracket 31 is used to install the lens 2 (as shown in FIG5 ). Exemplarily, the central axis of the focus bracket 31 is parallel to the optical axis of the lens 2 .

[0240] FIG27 is a fifth schematic diagram of a partial structure of the motor 1 shown in FIG6 in some embodiments.

[0241] As shown in FIG. 26 and FIG. 27 , in some embodiments, the focusing magnetic member 322 may be installed in the fifth installation slot 312 of the focusing bracket 31 to be fixed to the focusing bracket 31 .

[0242] Exemplarily, the focusing magnetic part 322 may include one or more magnets, and the implementation structure of the focusing magnetic part 322 may be various. For example, in some embodiments, the focusing magnetic part 322 may adopt a dual magnet solution, for example, consisting of two magnets, the two magnets are arranged in the first direction Y, and the polarity directions are opposite. In other embodiments, the focusing magnetic part 322 is a Halbach magnet array. In other embodiments, the focusing magnetic part 322 may adopt a single magnet solution, for example, consisting of a magnet, the magnet including two parts with opposite polarity directions. The magnet can be made using a bipolar magnetization process. In the embodiment of the present application, the focusing magnetic part 322 is taken as an example of a Halbach magnet array, and the present application does not limit this.

[0243] As shown in Figures 26 and 27, in some embodiments, the focusing bracket 31 may include a focusing bracket body 31a and a focusing magnetic conductive member 31b, and the focusing magnetic conductive member 31b is fixed between the focusing bracket body 31a and the focusing magnetic member 322 to enhance the magnetic field directivity of the focusing magnetic member 322. Exemplarily, the focusing magnetic conductive member 31b can be formed into an integrally formed structural member with the focusing bracket body 31a by means of insert-molding or the like. At this time, the focusing magnetic conductive member 31b is embedded in the focusing bracket 31. In other embodiments, the focusing magnetic conductive member 31b is mainly distributed between the focusing magnetic member 322 and the bottom wall of the fifth mounting groove 312. Among them, the focusing magnetic conductive member 31b can be fixed to the focusing bracket body 31a by means of bonding or the like, and the focusing magnetic member 322 can be fixed to the focusing magnetic conductive member 31b by means of bonding or the like.

[0244] Fig. 28 is a partial structural exploded view of the motor 1 shown in Fig. 6 in some embodiments. Fig. 29 is a sixth partial structural schematic view of the motor 1 shown in Fig. 6 in some embodiments.

[0245] As shown in Figures 28 and 29, for example, the focusing bracket 31 is installed on the inner side of the anti-shake bracket 21, and the third through hole 311 and the second through hole 2113 at least partially overlap. In other words, it can also be considered that the focusing bracket 31 and the anti-shake bracket 21 are coaxially nested, which is beneficial to improve the compactness of the arrangement of the structural parts in the motor 1, and can also improve the utilization rate of the space in the motor 1, which is conducive to the miniaturization of the motor 1.

[0246] In some embodiments, the focusing magnetic member 322 is arranged opposite to the focusing coil 321. At this time, the third slide groove 313 is arranged corresponding to the first slide groove 2141, and the fourth slide groove 314 is arranged corresponding to the second slide groove 2142. Exemplarily, the number of guide rods 34 can be two, and the two guide rods 34 include a first guide rod 341 and a second guide rod 342. A portion of the first guide rod 341 is located in the first slide groove 2141, and another portion of the first guide rod 341 is located in the third slide groove 313; a portion of the second guide rod 342 is located in the second slide groove 2142, and another portion of the second guide rod 342 is located in the fourth slide groove 314. Exemplarily, the shape, size, and material of the two guide rods 34 can be the same or different. In the embodiment of the present application, the first guide rod 341 is longer than the second guide rod 342 in the third direction Z as an example for description.

[0247] It is understood that the focus bracket 31 can be slidably connected to the anti-shake bracket 21 via the first guide rod 341 and the second guide rod 342, and the relative sliding direction between the two is parallel to the guide direction of the guide rod 34, that is, the third direction Z. In other embodiments, the focus bracket 31 can also be slidably connected to the anti-shake bracket 21 via ball bearings, and the arrangement direction of the multiple ball bearings is the guide direction.

[0248] In some embodiments, the guide rod 34 is made of ceramic material. By setting the guide rod 34 to be made of ceramic material, the manufacturing cost of the guide rod 34 can be effectively reduced, and the weight of the guide rod 34 can be reduced, so that the guide rod 34 can be firmly fixed on the anti-shake bracket 21 or the focus bracket 31 by gluing or other methods, which is also beneficial to reducing the manufacturing difficulty of the motor 1.

[0249] In some embodiments, the fit between the guide rod 34 and the focus bracket 31 includes both a tight fit and a loose fit to reduce assembly difficulty. For example, as shown in Figure 24, the third and fourth slots 313, 314 of the focus bracket 31 include at least one V-shaped slot and at least one U-shaped or L-shaped slot. When the V-shaped slot mates with the guide rod 34, the side walls of the V-shaped slot contact the guide rod 34, achieving a tight fit. For example, the third slot 313 may be a V-shaped slot. When the U-shaped or L-shaped slot mates with the guide rod 34, the side walls of the U-shaped or L-shaped slot contact the guide rod 34, achieving a loose fit. For example, the third slot 313 may be a V-shaped slot, with the first guide rod 341 and the third slot 313 achieving a tight fit, while the fourth slot 314 may be an L-shaped slot, with the second guide rod 342 and the fourth slot 314 achieving a loose fit.

[0250] It is understandable that in some other embodiments, the tight fit and loose fit designs between the guide rod 34 and the focus bracket 31 or the anti-shake bracket 21 may have other implementation schemes, and the embodiments of the present application do not strictly limit this.

[0251] FIG30 is a partial cross-sectional schematic diagram of the motor 1 shown in FIG29 taken along GG in some embodiments.

[0252] As shown in Figure 30, the focus coil 321 is fixed to the anti-shake bracket 21, the focus magnetic part 322 is fixed to the focus bracket 31, and the focus coil 321 is arranged facing the focus magnetic part 322, and is used to drive the focus bracket 31 to move relative to the anti-shake bracket 21 along the third direction Z. When the focus bracket 31 moves relative to the anti-shake bracket 21 along the third direction Z, the focus bracket 31 can drive the lens 2 (as shown in Figure 5) mounted thereon to move along the third direction Z. At this time, the motor 1 can realize the focusing function. Among them, the focus coil 321 is arranged facing the focus magnetic part 322, which means that the winding plane of the focus coil 321 faces the focus magnetic part 322. For example, the focus sensor 333 fixed to the focus circuit board 331 can be used to detect the position change of the focus bracket 31 in the third direction Z.

[0253] In this embodiment, during the movement of the focusing bracket 31 relative to the anti-shake bracket 21, the movement direction of the focusing bracket 31 is perpendicular to the magnetic gap between the focusing magnetic part 322 and the focusing coil 321. The above-mentioned magnetic gap is not affected by the movement of the focusing bracket 31. Therefore, the problem of rapid decrease in driving force due to the increase in the magnetic gap can be avoided, thereby ensuring that the focusing driving force of the motor 1 is large and the driving force is relatively stable, which is conducive to the large stroke design of the focusing function of the motor 1.

[0254] The focus drive mechanism 32, compensation mechanism 23, first anti-shake drive mechanism 22a and second anti-shake drive mechanism 22b of motor 1 are all dynamic magnetic designs, and the drive of motor 1 in the first direction Y, second direction X and third direction Z are all individually controlled by a group of drive components (including coils and magnetic components). Among them, when the focus bracket 31 of the motor 1 moves relative to the anti-shake bracket 21 along the third direction Z and performs autofocus, the relative position of the anti-shake bracket 21 and the base 11 is not affected, and the magnetic gap widths of the first anti-shake drive mechanism 22a, the second anti-shake drive mechanism 22b and the compensation mechanism 23 are not easily changed. Similarly, when the anti-shake bracket 21 moves relative to the base 11 along the first direction Y and / or the second direction X to perform optical image stabilization, the focus bracket 31 moves with the anti-shake bracket 21, and the relative positions of the two are not affected, and the magnetic gap width of the focus drive mechanism 32 is not easily changed. Therefore, the focus drive mechanism 32 of the motor 1 is decoupled from the first anti-shake drive mechanism 22a, the second anti-shake drive mechanism 22b and the compensation mechanism 23, and do not interfere with each other during movement, which is conducive to ensuring the driving accuracy of the motor 1.

[0255] In addition, since the focus bracket 31 is located on the inner side of the anti-shake bracket 21, the focus coil 321 is fixed to the anti-shake bracket 21, and the focus magnetic part 322 is fixed to the focus bracket 31, the optical image stabilization movable subassembly of the motor 1 wraps the focus movable subassembly. It can be understood that when the focus bracket 31 is located on the inner side of the anti-shake bracket 21, the anti-shake bracket 21 can be arranged around the focus bracket 31. Surrounding can be that the anti-shake bracket 21 is arranged around the focus bracket 31, or it can be that a part of the anti-shake bracket 21 is arranged around the focus bracket 31. In this embodiment, the anti-shake bracket 21 is annular. At this time, the anti-shake bracket 21 is arranged around the focus bracket 31.

[0256] It will be appreciated that in some embodiments, the anti-shake bracket 21 is located inside the focus bracket 31. In this case, when the camera module 100 needs to focus, the focus bracket 31 needs to drive the anti-shake bracket 21 and lens 2 along the third direction Z. This makes the moving element composed of the focus bracket 31, the anti-shake bracket 21, and the lens 2 relatively heavy, requiring the focus drive mechanism 32 to increase its size to increase its driving force. Therefore, this arrangement is detrimental to the lightweight and compact design of the motor 1. In this embodiment, the focus bracket 31 is located inside the anti-shake bracket 21. In this case, when the camera module 100 needs to focus, the focus bracket 31 needs to drive the lens 2 along the third direction Z. This allows the anti-shake bracket 21 to be omitted from the moving element during the focusing process. That is, the moving element composed of the focus bracket 31 and lens 2 is relatively lightweight, which facilitates the compact design of the focus drive mechanism 32. The motor 1 of this embodiment achieves a lightweight and compact design.

[0257] It's understandable that, compared to the solution where the anti-shake bracket 21 is located inside the focus bracket 31, the anti-shake bracket 21 requires at least two anti-shake drive assemblies to propel the anti-shake bracket 21 in the XY plane. Consequently, the motor 1 requires at least two sets of wiring to provide signals and power to the anti-shake drive assemblies. Furthermore, at least two sets of wiring must pass through the focus bracket 31. Therefore, this solution's power supply configuration is more complex, increasing the difficulty of setting up the motor 1. In contrast, by placing the focus bracket 31 inside the anti-shake bracket 21, the focus bracket 31 requires a set of focus drive mechanisms 32 to propel it in the third direction Z. This also requires a set of wiring to provide signals and power to the focus drive mechanisms 32, meaning that one set of wiring must pass through the anti-shake bracket 21. Therefore, the power supply configuration of this embodiment is relatively simple, significantly reducing the difficulty of setting up the motor 1.

[0258] As shown in Figure 30, the winding plane of the focus coil 321 can be parallel to the third direction Z. In this case, the focus coil 321 is arranged vertically, so that the focus coil 321 can occupy a smaller area in the XY plane, which is beneficial to the miniaturization of the motor 1. The focus magnetic part 322 can include two opposite polarity directions, both of which are perpendicular to the third direction Z. In this case, the focus magnetic part 322 can be arranged vertically, thereby reducing the space occupied by the focus magnetic part 322 in the XY plane, which is convenient for the miniaturization design of the motor 1.

[0259] Fig. 31 is a partial structural exploded view of the motor 1 shown in Fig. 6 in some embodiments. Fig. 32 is a partial structural schematic view seven of the motor 1 shown in Fig. 31 in some embodiments.

[0260] As shown in Figures 31 and 32 , in some embodiments, the number of reeds 13 can be four, and the four reeds 13 can include a first reed 131, a second reed 132, a third reed 133, and a fourth reed 134. The four reeds 13 can be arranged in a plane perpendicular to the third direction Z and located on the side of the anti-shake bracket 21 facing away from the base plate 111. For example, the first reed 131 can include a first connecting end 13a, a second connecting end 13b, and a third connecting end 13c, which are connected in sequence. Each portion of the first reed 131 can be bent multiple times. This effectively reduces the elastic modulus of the first reed 131. The second reed 132, the third reed 133 and the fourth reed 134 may also include a first connection end 13a, a second connection end 13b and a third connection end 13c, respectively. The positions of the first connection end 13a, the second connection end 13b and the third connection end 13c in the corresponding second reed 132, the third reed 133 or the fourth reed 134 may refer to the positional relationship between the first connection end 13a, the second connection end 13b and the third connection end 13c in the above-mentioned first reed 131, and will not be further described in this application.

[0261] Illustratively, the first connection ends 13a of the four reeds 13 are respectively arranged corresponding to the four corners of the anti-shake bracket 21, the second connection ends 13b of the four reeds 13 are all arranged corresponding to the second side 211b of the anti-shake bracket 21 and are spaced apart from each other, and the third connection ends 13c of the four reeds 13 are all arranged corresponding to the fourth side 211d of the anti-shake bracket 21 and are spaced apart from each other. The four reeds 13 surround at least a portion of the third through hole 311, the first reed 131 and the fourth reed 134 are located on the same side of the third through hole 311, and the second reed 132 and the third reed 133 are located on the other side opposite the third through hole 311.

[0262] For example, the first connecting end 13a of the reed 13 can be provided with a limiting hole 135, and the second fixed end 12b of the suspension wire 12 can be embedded in the limiting hole 135 to achieve a fixed connection between the suspension wire 12 and the reed 13. The limiting hole 135 can be a gap formed by bending the first connecting end 13a of the reed 13 multiple times, or the limiting hole 135 can also be a through hole opened on the first connecting end 13a of the reed 13, and this application does not limit this. In other embodiments, the first connecting end 13a of the reed 13 may not include the limiting hole 135, and the second fixed end 12b of the suspension wire 12 can be connected to the reed 13 by gluing, welding, etc., and the first connecting ends 13a of the four reeds 13 correspond one to one with the four suspension wires 12. For example, the first connecting end 13a of the first reed 131 can be connected to the second fixed end 12b of the first suspension wire 121, the first connecting end 13a of the second reed 132 can be connected to the second fixed end 12b of the second suspension wire 122, the first connecting end 13a of the third reed 133 can be connected to the second fixed end 12b of the third suspension wire 123, and the first connecting end 13a of the fourth reed 134 can be connected to the second fixed end 12b of the fourth suspension wire 124.

[0263] For example, the reed 13 may further be provided with a plurality of fixing holes 136 , which correspond one-to-one to the plurality of fixing posts 212 . The fixing posts 212 may be embedded in the fixing holes 136 to achieve a fixed connection between the reed 13 and the anti-shake bracket 21 .

[0264] When the anti-shake bracket 21 moves relative to the base 11 in the first direction Y or the second direction X, the four suspension wires 12 undergo elastic deformation. The combined restoring force generated by the four suspension wires 12 is directed in the opposite direction of the anti-shake bracket 21's movement relative to the base 11, driving the anti-shake bracket 21 to move in the opposite direction relative to the base 11, returning the anti-shake bracket 21 to its equilibrium position. This improves the linearity of the anti-shake bracket 21's movement and helps maintain the center of the anti-shake bracket 21 along the optical axis, thereby enhancing the reliability and control accuracy of the motor 1. In the embodiment of the present application, the suspension wires 12 are connected to the anti-shake bracket 21 via the spring 13. In other embodiments, the second fixed end 12b of the suspension wire 12 may also be connected to the anti-shake bracket 21 via other structural members or directly, and this application is not limited thereto.

[0265] In some embodiments, the reed 13 may also be made of conductive material to take into account the signal transmission function.

[0266] FIG33 is a schematic structural diagram of the motor 1 shown in FIG4 at another angle.

[0267] As shown in FIG33 , illustratively, the motor housing 14 may include a top plate 141 and a side frame 142 , wherein the side frame 142 is connected to the periphery of the top plate 141 ; the top plate 141 is provided with a first raised area 1411 and a second raised area 1412 that are oppositely arranged.

[0268] In some embodiments, the motor housing 14 is assembled and mated with the base 11. The motor housing 14 covers the base 11, and the motor housing 14 and the base 11 cooperate to encapsulate and protect the internal structure of the motor 1. The top plate 141 is provided with a fourth through-hole 143. The fourth through-hole 143 penetrates the top plate 141 in the third direction Z, and a portion of the structure of the motor 1 is exposed through the fourth through-hole 143, such as a portion of the structure of the focus bracket 31.

[0269] Fig. 34 is a schematic diagram of a partial structural decomposition of the motor 1 shown in Fig. 33 in some embodiments. Fig. 35 is a schematic diagram of a partial structural decomposition of the motor 1 shown in Fig. 34 in some embodiments.

[0270] As shown in Figures 34 and 35, in some embodiments, the motor 1 may further include a first buffer 161. The first buffer 161 may be fixed to the surface of the focus bracket 31 facing away from the bottom plate 111. There may be two first buffers 161, with the two first buffers 161 corresponding to the first raised area 1411 and the second raised area 1412, respectively. The first buffer 161 is provided to reduce the impact force between the focus bracket 31 and the motor housing 14 when the focus bracket 31 moves upward along the third direction Z, thereby preventing the focus bracket 31 from being damaged by impacting the top plate 141 during movement. Exemplarily, the first buffer 161 may be made of a flexible material such as liquid silicone or foam. The first buffer 161 may be formed into an integrated structure with the focus bracket 31 through an injection molding process. In other embodiments, the first buffer 161 may also be fixed to the focus bracket 31 by bonding or other fixing methods, which is not limited in this application. For example, the sizes and shapes of the two first buffer members 161 may be the same or different, which is not limited in this application. In other embodiments, the number of the first buffer members 161 may be one or four, which is not limited in this application.

[0271] In some embodiments, the motor 1 may further include a second buffer 162, which may be fixed to the surface of the focus bracket 31 facing the bottom plate 111. The number of second buffers 162 may be four, and the four second buffers 162 may be fixed to the four corners of the focus bracket 31. By providing the second buffer 162, when the focus bracket 31 moves downward along the third direction Z, the impact force between the focus bracket 31 and the base 11 is reduced to prevent the focus bracket 31 from being damaged by impacting the base 11 during movement. Exemplarily, the second buffer 162 may be made of a flexible material such as liquid silicone or foam, and the second buffer 162 may be formed into an integrated structure with the focus bracket 31 through an injection molding process. In other embodiments, the second buffer 162 may also be fixed to the focus bracket 31 by bonding or other fixing methods, which is not limited in this application. Exemplarily, the size, shape, etc. of the four second buffers 162 may be the same or different, which is not limited in this application. In other embodiments, the number of the second buffer members 162 may also be two or three, etc., and this application does not limit this.

[0272] In some embodiments, the motor 1 may further include a third buffer member 163. This third buffer member 163 may be fixed to the side of the anti-shake bracket 21 facing the side frame 142. Four third buffer members 163 may be provided, one fixed to each side of the anti-shake bracket 21. The third buffer member 163 serves to reduce the impact force between the anti-shake bracket 21 and the motor housing 14 when the anti-shake bracket 21 moves relative to the base 11 in the XY plane, thereby preventing damage to the anti-shake bracket 21 from impacting the side frame 142 during movement. For example, the third buffer member 163 may be made of a flexible material such as liquid silicone or foam, and may be integrated with the anti-shake bracket 21 through an injection molding process. In other embodiments, the third buffer member 163 may be fixed to the anti-shake bracket 21 through bonding or other fixing methods, which is not limited in this application. For example, the four third buffer members 163 may have the same or different sizes and shapes, which is not limited in this application. In other embodiments, the number of the third buffer members 163 may also be two or three, etc., and this application does not limit this.

[0273] In some embodiments, the motor 1 may further include an anti-shake magnetic component 17, which is fixed to the second surface 111b of the base plate 111. Exemplarily, the anti-shake magnetic component 17 may include a first anti-shake magnetic component 171 and a second anti-shake magnetic component 172. The first anti-shake magnetic component 171 is located in the first edge region 1111 and faces the first anti-shake magnetic component 222, generating a magnetic attraction with the first anti-shake magnetic component 222 to attach the anti-shake bracket 21 to the base 11. The second anti-shake magnetic component 172 may be fixed to the second edge region 1112 and faces the second anti-shake magnetic component 224, generating a magnetic attraction with the second anti-shake magnetic component 224 to attach the anti-shake bracket 21 to the base 11. Exemplarily, the anti-shake magnetic component 17 may be made of a material capable of generating a magnetic attraction with a magnet or other magnetic component, such as a ferromagnetic material. The first anti-shake magnetic component 171 and the second anti-shake magnetic component 172 may be the same or different in size and shape, and this application does not limit this. In other embodiments, the motor 1 may not include the first anti-shake magnetic component 171, or the motor 1 may not include the second anti-shake magnetic component 172.

[0274] In this embodiment, since the anti-shake bracket 21 tends to approach the base 11 under the magnetic force, it can be ensured that the anti-shake bracket 21 maintains contact with the ball group 24, thereby achieving precise guidance during the movement of the anti-shake bracket 21 relative to the base 11, thereby improving the reliability and accuracy of optical image stabilization.

[0275] The circuit arrangement between the motor 1 and the module circuit board 3 will be described in detail below with reference to the relevant drawings.

[0276] FIG36 is a partial structural diagram of an embodiment of a circuit electrically connecting the focus driving chip 332 to an external structure according to an embodiment of the present application.

[0277] As shown in Figure 36, exemplarily, multiple traces 215 may include a first trace 2151, a second trace 2152, a third trace 2153 and a fourth trace 2154. The above multiple traces 215 may all be conductive traces, or they may respectively adopt flexible circuit board structures, which is not limited in this application.

[0278] Illustratively, the first routing line 2151 includes an input end 215a and an output end 215b, and both the input end and the output end of the first routing line 2151 are exposed relative to the anti-shake bracket 21. Illustratively, the second routing line 2152, the third routing line 2153, and the fourth routing line 2154 may also include an input end 215a and an output end 215b, respectively. The positions of the input end 215a and the output end 215b within the corresponding second routing line 2152, the third routing line 2153, and the fourth routing line 2154 may refer to the positional relationship between the input end 215a and the output end 215b in the first routing line 2151 described above, and this application will not further describe this.

[0279] Exemplarily, the access ends 215 a of the plurality of traces 215 are electrically connected to the plurality of ports of the focus driving chip 332 through the focus circuit board 331 in a one-to-one correspondence.

[0280] For example, the input end 215a of the first trace 2151 can be exposed relative to the surface of the anti-shake bracket 21 (as shown in FIG13 ). The input end 215a of the first trace 2151 can be electrically connected to the SCL signal terminal of the focus driver chip 332 via the focus circuit board 331. The output end 215b of the first trace 2151 can be exposed relative to the top surface 2111 of the anti-shake bracket 21 (as shown in FIG12 ). It is understood that the SDA signal terminal can be used to transmit the serial data (SDA) signal of the I2C signal.

[0281] For example, the input end 215a of the second trace 2152 can be exposed relative to the surface of the anti-shake bracket 21 (as shown in FIG13 ). The input end 215a of the second trace 2152 can be electrically connected to the SCL signal end of the focus driver chip 332 via the focus circuit board 331. The output end 215b of the second trace 2152 can be exposed relative to the top surface 2111 of the anti-shake bracket 21 (as shown in FIG12 ) and spaced apart from the output end 215b of the first trace 2151. It will be understood that the SCL signal end can be used to transmit the serial clock (SCL) signal of the I2C signal.

[0282] For example, the input end 215a of the third trace 2153 can be exposed relative to the surface of the anti-shake bracket 21 (as shown in FIG13 ). The input end 215a of the third trace 2153 can be electrically connected to the positive power supply terminal of the focus driver chip 332 via the focus circuit board 331. The output end 215b of the third trace 2153 can be exposed relative to the top surface 2111 of the anti-shake bracket 21 (as shown in FIG12 ) and spaced apart from the output end 215b of the first trace 2151 and the output end 215b of the second trace 2152.

[0283] For example, the input end 215a of the fourth trace 2154 can be exposed relative to the surface of the anti-shake bracket 21 (as shown in FIG13 ). The input end 215a of the fourth trace 2154 can be electrically connected to the negative power supply terminal of the focus driver chip 332 via the focus circuit board 331. The output end 215b of the fourth trace 2154 can be exposed relative to the top surface 2111 of the anti-shake bracket 21 (as shown in FIG12 ) and spaced apart from the output end 215b of the first trace 2151, the output end 215b of the second trace 2152, and the output end 215b of the third trace 2153.

[0284] In other embodiments, the first trace 2151, the second trace 2152, the third trace 2153, and the fourth trace 2154 may each utilize a flexible circuit board structure. Alternatively, the first trace 2151, the second trace 2152, the third trace 2153, and the fourth trace 2154 may be integrated into a single flexible circuit board. This will be described in detail below with reference to the accompanying drawings.

[0285] In some embodiments, the first spring 131, the second spring 132, the third spring 133, and the fourth spring 134 can all be metal spring structures and can deform under stress, that is, have a stretchable effect. In other embodiments, the plurality of springs 13 can also be conductive traces or each can be a flexible circuit board structure, which is not limited in this application.

[0286] Exemplarily, the second connection end 13b of the reed 13 can be electrically connected to the connection end 215b of the multiple traces 215 in a one-to-one correspondence, and the first connection end 13a and the third connection end 13c of the reed 13 can be electrically connected to the external structure of the motor 1 in a one-to-one correspondence. At this time, the second connection ends 13b of the multiple reeds 13 are electrically connected to the focus driver chip 332 through the multiple traces 215 in a one-to-one correspondence. In other words, the multiple reeds 13 can respectively serve as transmission channels for the signals of each port of the focus driver chip 332, and external structures such as the module circuit board 33 (as shown in Figure 2) or the variable aperture 6 can be electrically connected to the focus driver chip 332 by electrically connecting the first connection end 13a of the reed 13 or the third connection end 13c of the reed 13.

[0287] For example, the second connection end 13b of the first reed 131 can be electrically connected to the output end 215b of the first trace 2151. In this case, the first reed 131 can be electrically connected to the SDA signal terminal of the focus driver chip 332 via the first trace 2151. The second connection end 13b of the second reed 132 can be electrically connected to the output end 215b of the second trace 2152. In this case, the second reed 132 can be electrically connected to the SCL signal terminal of the focus driver chip 332 via the second trace 2152. The second connection end 13b of the third reed 133 can be electrically connected to the output end 215b of the third trace 2153. In this case, the third reed 133 can be electrically connected to the positive power supply terminal of the focus driver chip 332 via the third trace 2153. The second connection end 13b of the fourth reed 134 can be electrically connected to the output end 215b of the fourth trace 2154. At this time, the fourth reed 134 can be electrically connected to the negative power terminal of the focus driver chip 332 through the fourth trace 2154 .

[0288] The second connection end 13b of the first spring 131 can be fixedly connected to the connection end 215b of the first trace 2151 by welding or conductive adhesive. The connection method between the second connection end 13b of the second spring 132 and the connection end 215b of the second trace 2152, the connection method between the second connection end 13b of the third spring 133 and the connection end 215b of the third trace 2153, and the connection method between the second connection end 13b of the fourth spring 134 and the connection end 215b of the fourth trace 2154 can refer to the connection method between the second connection end 13b of the first spring 131 and the connection end 215b of the first trace 2151, and will not be repeated here.

[0289] For example, the third connection end 13c of the first reed 131 can also be electrically connected to the SDA signal of the driver chip of the variable aperture 6 (as shown in FIG2 ). The third connection end 13c of the second reed 132 can be electrically connected to the SCL signal of the driver chip of the variable aperture 6. The third connection end 13c of the third reed 133 can be electrically connected to the positive power supply of the driver chip of the variable aperture 6. The third connection end 13c of the fourth reed 134 can be electrically connected to the negative power supply of the driver chip of the variable aperture 6. In other words, the reed 13 can also serve as a transmission channel between the various port signals of the variable aperture 6 and the various port signals of the focus driver chip 332. External structures such as the variable aperture 6 (as shown in FIG2 ) can be electrically connected to the variable aperture 6 by electrically connecting the reed 13.

[0290] FIG37 is a structural diagram of an embodiment of a circuit in which the motor 1 shown in FIG4 is electrically connected to an external structure.

[0291] As shown in Figure 37, exemplarily, the suspension wire 12 can be a conductive material, and the suspension wire 12 can serve as a transmission channel between the reed 13 and the module circuit board 3 (as shown in Figure 4). At this time, the first fixed ends 12a of the four suspension wires 12 (as shown in Figure 10) can be electrically connected to the four extension parts 1153 (as shown in Figure 8) one by one, and the second fixed ends 12b of the four suspension wires 12 can be electrically connected to the first connection ends 13a of the four reeds 13 one by one, so as to realize the electrical connection between the focus drive chip 332 or the variable aperture 6 (as shown in Figure 4) and the module circuit board 3.

[0292] For example, the second fixed end 12b of the first suspension wire 121 can be electrically connected to the first connection end 13a of the first spring 131, the second fixed end 12b of the second suspension wire 122 can be electrically connected to the first connection end 13a of the second spring 132, the second fixed end 12b of the third suspension wire 123 can be electrically connected to the first connection end 13a of the third spring 133, and the second fixed end 12b of the fourth suspension wire 124 can be electrically connected to the first connection end 13a of the fourth spring 134.

[0293] In the above embodiments, the anti-shake drive mechanism of the motor 1 mainly adopts a single-coil drive scheme. In other embodiments, the motor 1 can also adopt a dual-coil drive scheme to provide greater driving force, which is conducive to improving driving efficiency and increasing the optical anti-shake range. For example:

[0294] FIG38 is a schematic diagram of a partial structure of another motor 1 provided in an embodiment of the present application.

[0295] As shown in FIG38 , in some embodiments, the first anti-shake coil 221 may include a first sub-anti-shake coil 2211 and a second sub-anti-shake coil 2212. The first sub-anti-shake coil 2211 may be disposed facing the first anti-shake magnetic component 222, and the second sub-anti-shake coil 2212 may be disposed facing the first anti-shake magnetic component 222. In other words, the first sub-anti-shake coil 2211 and the second sub-anti-shake coil 2212 may share the magnetic field generated by the first anti-shake magnetic component 222.

[0296] For example, the second anti-shake coil 223 may include a third sub-anti-shake coil 2231 and a fourth sub-anti-shake coil 2232. The third sub-anti-shake coil 2231 may be arranged facing the second anti-shake magnetic component 224, and the fourth sub-anti-shake coil 2232 may be arranged facing the second anti-shake magnetic component 224. In other words, the third sub-anti-shake coil 2231 and the fourth sub-anti-shake coil 2232 can share the magnetic field generated by the second anti-shake magnetic component 224.

[0297] At this time, by adjusting the magnitude and direction of the current of the compensation coil 231 in the compensation mechanism 23, it can also be used to compensate for the torque generated by the first sub-anti-shake coil 2211, the second sub-anti-shake coil 2212, the third sub-anti-shake coil 2231 and / or the fourth sub-anti-shake coil 2232 at the center of the anti-shake bracket 21, ensuring that the resultant torque M4 acting on the anti-shake bracket 21 is zero, so that the anti-shake bracket 21 will not deflect, which is beneficial to improving the control accuracy and reliability of the motor 1.

[0298] In the previous embodiment, the motor 1 primarily utilizes a suspension wire 12 to provide a restoring force. In other embodiments, the motor 1 may also utilize an elastic member 18 for guidance. For example, this embodiment may incorporate most of the technical solutions of the previous embodiment. The following primarily describes the differences between the two embodiments, and omitted any further details regarding the commonalities between the two.

[0299] FIG39 is a schematic diagram of a partial structure of another motor 1 provided in an embodiment of the present application.

[0300] As shown in FIG39 , in some embodiments, the base 11 may further include four fixing blocks 117, which are respectively fixed to the four corners of the bottom plate 111. The fixing blocks 117 may be provided with a receiving groove 1171. The receiving groove 1171 may be fixed to the bottom plate 111 and located on the side of the fixing block 117 away from the first through hole 1115. The opening direction of the receiving groove 1171 may be located on the same side of the bottom plate 111 as the first surface 111a. The motor 1 may further include an elastic member 18, which may be fixedly connected to the fixing blocks 117. For example, the number of elastic members 18 may be four, and the four elastic members 18 may be fixedly connected to the four fixing blocks 117 in a one-to-one correspondence. The four elastic members 18 may all be the same in shape and size, and the four elastic members 18 may use the same reference numeral. It is understandable that the present application does not limit the number of elastic members 18.

[0301] Exemplarily, the elastic member 18 may include a first end 181 of the elastic member 18, a middle portion 182 of the elastic member 18 and a second end 183 of the elastic member 18. The middle portion 182 of the elastic member 18 may be bent and connected between the first end 181 of the elastic member 18 and the second end 183 of the elastic member 18. The first end 181 of the elastic member 18 may be bent and connected relative to the middle portion 182 of the elastic member 18. The first end 181 of the elastic member 18 may be fixedly connected to the corresponding fixed block 117. The middle portion 182 of the elastic member 18 may be installed in the accommodating groove 1171. The fixed block 117 may fix and support the elastic member 18, thereby realizing a fixed connection between the elastic member 18 and the base 11.

[0302] For example, a positioning hole 1831 may be defined on the second end 183 of the elastic member 18, and a corresponding positioning post 1832 may be defined on the anti-shake bracket 21. The positioning post 1832 may be inserted into the positioning hole 1831 to achieve connection between the elastic member 18 and the anti-shake bracket 21. In other words, the elastic member 18 is connected between the anti-shake bracket 21 and the base 11. When the anti-shake bracket 21 moves relative to the base 11 in the first direction Y or the second direction X, the four elastic members 18 undergo elastic deformation. The combined restoring force generated by the four elastic members 18 is directed in the opposite direction of the movement of the anti-shake bracket 21 relative to the base 11, thereby driving the anti-shake bracket 21 to move in the opposite direction relative to the base 11, returning the anti-shake bracket 21 to a balanced position. This improves the linearity of the movement of the anti-shake bracket 21 and helps maintain the center of the anti-shake bracket 21 along the optical axis, thereby enhancing the reliability and control accuracy of the motor 1.

[0303] For example, the elastic member 18 may also be made of a conductive material, and the elastic member 18 may serve as a transmission channel between the reed 13 and the module circuit board 3 .

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
