Description

Technical Field

[0001] This application relates to the field of camera technologies, and particularly to a motor, a camera module, and an electronic device. Background Art

[0002] A camera module is usually provided in an electronic device for taking pictures. When taking pictures or shooting videos, the camera module may shake due to external vibration, affecting the image quality on the image sensor.

[0003] Many anti-shake technologies have emerged in the market, such as optical image stabilization (OIS). According to the collected jitter stroke, an OIS motor drives the lens to perform a reverse compensation movement in a plane perpendicular to the optical axis to offset the jitter amount and achieve anti-shake. However, when a traditional motor drives the lens to translate in one direction, the lens will also generate an additional displacement amount in other directions, resulting in low driving control accuracy of the optical image stabilization and poor reliability of the motor. Summary of the Invention

[0004] The purpose of the embodiments of this 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 high reliability.

[0005] In a first aspect, this application provides a motor. The motor includes a base, an anti-shake bracket, a first anti-shake magnetic member, a second anti-shake magnetic member, a first anti-shake coil, a second anti-shake coil, a compensation coil, and a compensation magnetic member. 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 member is fixed to the first side portion, and the second anti-shake magnetic member 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 member and is used to drive the anti-shake bracket to move relative to the base in a first direction. The second anti-shake coil faces the second anti-shake magnetic member and is used to drive the anti-shake bracket to move relative to the base in a second direction. The second direction intersects the first direction. The compensation magnetic member is fixed to the anti-shake bracket, and the compensation coil is fixed to the base. The compensation coil is arranged facing the compensation magnetic member. The first anti-shake magnetic member has a first axis that passes through the center of the first anti-shake magnetic member and is parallel to the first direction. The second anti-shake magnetic member also has a second axis that passes through the center of the second anti-shake magnetic member and is parallel to the second direction. The center of the compensation magnetic member is offset from both the first axis and the second axis.

[0006] It can be understood that during the movement of the anti-shake bracket relative to the base along the first direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the first anti-shake magnetic member and the first anti-shake coil. The above magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of rapid decline in driving force caused by the increase in the magnetic gap can be avoided, ensuring that the anti-shake driving force of the motor is relatively large and the driving force is relatively stable, which is beneficial to the large-stroke design of the optical anti-shake function of the motor.

[0007] It can be understood that during the movement of the anti-shake bracket relative to the base along the second direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the second anti-shake magnetic member and the second anti-shake coil. The above magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of rapid decline in driving force caused by the increase in the magnetic gap can be avoided, ensuring that the anti-shake driving force of the motor is relatively large and the driving force is relatively stable, which is beneficial to the large-stroke design of the optical anti-shake function of the motor.

[0008] When the anti-shake bracket moves relative to the base along the first direction or the second direction, the compensation magnetic member can be used to provide a first acting force. Among them, since the center of the compensation magnetic member is offset from both the first axis and the second axis, that is, the center of the compensation magnetic member is not on the first axis, and the center of the compensation magnetic member is not on the second axis, the first acting force can generate a compensation 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 received by the anti-shake bracket can be maintained at zero, and avoiding the anti-shake bracket from rotating relative to the base due to the non-zero resultant torque, which affects the control accuracy and reliability of the motor.

[0009] In a possible implementation, the compensation magnetic member is offset from both the first axis and the second axis. In this way, on the one hand, it can ensure that the center of the compensation magnetic member is offset from both the first axis and the second axis, and on the other hand, it can increase the torque of the compensation magnetic member.

[0010] In a possible implementation, the connecting section includes a third side portion and a fourth side portion. The third side portion is connected between the second side portion and the fourth side portion. The first side portion is disposed opposite to the third side portion, and the second side portion is disposed opposite to the fourth side portion; the compensation magnetic member is fixed to the third side portion or the fourth side portion. At this time, the compensation magnetic member, the first anti-shake magnetic member, and the second anti-shake magnetic member can be substantially in an L shape. 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 at two positions of the motor corresponding to the first side portion and the second side portion of the anti-shake bracket. One position of the motor corresponding to the third side portion of the anti-shake bracket is used to arrange the compensation magnetic member and the compensation coil, and no structural member is arranged at one position corresponding to the fourth side portion of the anti-shake bracket. Therefore, the motor can make full use of its three-side positions, and the remaining one-side position can minimize the volume as much as possible, which is beneficial to the miniaturization setting of the overall motor.

[0011] In a possible implementation, the compensating magnetic member is located on one side of the first axis close to the second anti-shake magnetic member. It can be understood that setting the compensating magnetic member close to the second anti-shake magnetic member can improve the utilization rate of the space on the side of the first axis close to the second anti-shake magnetic member, which is beneficial to the miniaturized design of the motor.

[0012] In a possible implementation, the winding plane of the compensating coil is perpendicular to the third direction, and the third direction is perpendicular to the first direction and the second direction.

[0013] It can be understood that during the movement of the anti-shake bracket relative to the base along the first direction or the second direction, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the compensating magnetic member and the compensating coil. The above magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of rapid decline in driving force caused by the increase of the magnetic gap can be avoided, so as to ensure that the driving force provided by the compensating magnetic member is large and the driving force is relatively stable.

[0014] At this time, the compensating coil is horizontally arranged, which is beneficial to reducing the occupied space of the compensating coil in the third direction and is beneficial to realizing the thin-type setting of the motor.

[0015] In a possible implementation, the compensating magnetic member is composed of one or more magnets, or the compensating magnetic member is a Halbach magnet array.

[0016] In a possible implementation, the length of the compensating magnetic member is less than the length of the first anti-shake magnetic member and the length of the second anti-shake magnetic member. At this time, the occupied space of the compensating magnetic member in the motor is small, which is beneficial to the miniaturization of the motor and can also reduce the manufacturing cost.

[0017] In a possible implementation, the motor further 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 amount of the first anti-shake magnetic member 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 amount of the second anti-shake magnetic member 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 amount of the compensating magnetic member when the anti-shake bracket moves along the first direction, and obtain the deflection amount of the anti-shake bracket according to the third magnetic field change amount and the first magnetic field change amount, and is also used to detect the fourth magnetic field change amount of the compensating magnetic member when the anti-shake bracket moves along the second direction, and obtain the deflection amount of the anti-shake bracket according to the fourth magnetic field change amount.

[0018] It can be understood that when the anti-shake bracket moves in the first direction, the first position sensor can detect the first magnetic field change amount of the first anti-shake magnetic member, and the third position sensor can detect the third magnetic field change amount of the compensation magnetic member. If the anti-shake bracket deflects, it will cause the displacements of the opposite sides of the anti-shake bracket in the first direction to be different. At this time, the first magnetic field change amount and the third magnetic field change amount will not be equal, and the deflection amount of the anti-shake bracket can be obtained according to the difference between the first magnetic field change amount and the third magnetic field change amount.

[0019] In this embodiment, when the anti-shake bracket moves in the second direction, the second position sensor can detect the second magnetic field change amount of the second anti-shake magnetic member, and the third position sensor can detect the fourth magnetic field change amount of the compensation magnetic member. If the anti-shake bracket deflects, it will cause the anti-shake bracket to have a displacement in the second direction. At this time, the fourth magnetic field change amount will not be zero, and the deflection amount of the anti-shake bracket can be obtained according to the fourth magnetic field change amount.

[0020] In a possible implementation manner, the motor further includes a ball group. The anti-shake bracket is movably connected to the base through the ball group, and the ball group is spaced apart from the compensation coil. Each ball group can include multiple balls. The number of balls can be five, sixteen, thirty-two, etc. The present application does not limit this. This embodiment realizes the movable connection between the anti-shake bracket and the focusing bracket through the ball group, which can reduce the frictional resistance between the balls and the anti-shake bracket while ensuring sufficient supporting force, can reduce the requirement for the magnitude of the driving force during the movement of the anti-shake bracket, that is, it is beneficial to reduce the size of the first magnetic member and / or the first anti-shake coil, and is beneficial to the miniaturization of the motor. Exemplarily, compared with the diameter of the traditional large ball, the diameter of each ball in the ball group of this embodiment is smaller, which is also beneficial to shortening the interval between the anti-shake bracket and the base and is beneficial to the thinning of the motor. In addition, the ball group can provide multi-point support for the anti-shake bracket, which is beneficial to dispersing stress and preventing the balls from deforming when being collided due to excessive stress concentration in a single direction, and can improve the reliability of the support of the ball group for structural components such as the anti-shake bracket and the lens.

[0021] In a 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 joint of the first side and the second side, the second ball group is connected to the joint of the second side and the third side, and the third ball group is connected to the joint of the fourth side and the first side; the compensation magnetic member is disposed close to the second ball group. The first ball group, the second ball group, and the third ball group can provide multi-point support for the anti-shake bracket, improve the stability of the relative position relationship between the anti-shake bracket and the ball group, make the movement of the anti-shake bracket safer and more reliable, and in this embodiment, the positions of the ball groups are arranged using the principle of triangle stability, which can reduce the number of ball groups in the motor while ensuring the reliability of the ball groups, and is beneficial to simplifying the structure of the motor. In other embodiments, the ball group may not include the third ball group; or, the ball group may further include a fourth ball group, and the present application does not limit this.

[0022] In a possible implementation, the base includes a bottom plate and a first metal member, and the first metal member is embedded in the bottom plate; the bottom plate is provided with a groove, the first metal member includes a support portion, the material of the support portion includes a metal material, at least a part of the support portion is exposed relative to the groove, the ball group is located in the groove and contacts the support portion. Exemplarily, the first metal member may be made of materials such as steel sheets, and the present application does not limit this.

[0023] It can be understood that by providing the support portion and the ball group is movably connected to the support portion, the friction force received by the ball group during movement can be reduced, the smoothness during the rotation of the balls can be improved, and it is beneficial to improve the response rate of the motor when the anti-shake bracket is movably connected to the base through the ball group.

[0024] In a possible implementation, the first metal member further includes a reinforcing portion, the reinforcing portion is connected to the support portion and is located on the side of the support portion away from the ball group. It can be understood that the reinforcing portion can provide a certain hardness support for the base, enhance the strength of the base, and prevent the base from deforming.

[0025] In a possible implementation, the motor further includes a first anti-shake magnetic member, the first anti-shake magnetic member is fixed to the base and is disposed facing the first anti-shake magnetic member to generate a magnetic attraction force with the first anti-shake magnetic member, and the magnetic attraction force causes the anti-shake bracket to be adsorbed on the base; and / or, the motor further includes a second anti-shake magnetic member, the second anti-shake magnetic member is fixed to the base and is disposed facing the second anti-shake magnetic member to generate a magnetic attraction force with the second anti-shake magnetic member, and the magnetic attraction force causes the anti-shake bracket to be adsorbed on the base. Through the magnetic force between the first anti-shake magnetic member and the first anti-shake magnetic member, and the magnetic force between the second anti-shake magnetic member and the second anti-shake magnetic member, the anti-shake bracket has a tendency to approach the base, thereby ensuring that contact is maintained between the base, the ball group, and the anti-shake bracket, achieving pre-tightening, and improving the reliability of the optical image stabilization process of the motor.

[0026] In a possible implementation, the motor further includes a focusing bracket located inside the anti-shake bracket and movably connected to the anti-shake bracket; a focusing magnetic member fixed to the anti-shake bracket; and a focusing coil fixed to the focusing bracket. The focusing coil is arranged facing the focusing magnetic member to drive the focusing bracket to move relative to the base along a third direction, and the third direction intersects the first direction.

[0027] It can be understood that by arranging the focusing bracket inside the anti-shake bracket, the focusing coil fixed to the anti-shake bracket, and the focusing magnetic member fixed to the focusing bracket, the moving component of the optical anti-shake of the motor wraps the moving component of the focusing. When the focusing bracket is located inside the anti-shake bracket, the anti-shake bracket can be arranged around the focusing bracket. The surrounding can be that the anti-shake bracket is arranged around the focusing bracket for one week, or a part of the anti-shake bracket is arranged around the focusing bracket. In this embodiment, the anti-shake bracket is in a frame shape. At this time, the anti-shake bracket is arranged around the focusing bracket.

[0028] It can be understood that in some solutions, the anti-shake bracket is located inside the focusing bracket. At this time, when the camera module needs to focus, the focusing bracket needs to drive the anti-shake bracket and the lens to move along the third direction. In this way, the weight of the moving component composed of the focusing bracket, the anti-shake bracket, and the lens is relatively heavy, resulting in that the focusing drive component needs to increase the volume to improve the driving force. Therefore, this setting is not conducive to the lightweight and miniaturized design of the motor. In this embodiment, by arranging the focusing bracket inside the anti-shake bracket. At this time, when the camera module needs to focus, the focusing bracket needs to drive the lens to move along the third direction. In this way, the moving component in the focusing process of this embodiment can omit the anti-shake bracket, that is, the weight of the moving component composed of the focusing bracket and the lens is relatively light, which is conducive to the miniaturized setting of the focusing drive component. The motor of this embodiment can achieve lightweight and miniaturized settings.

[0029] It can be understood that compared with the solution where the anti-shake bracket is inside the focusing bracket, at least two anti-shake drive components are required for the anti-shake bracket to push the anti-shake bracket to move in the X-Y plane. In this way, the motor also needs to arrange at least two sets of circuits to provide signals and power supply for the anti-shake drive components. And at least two sets of circuits need to pass through the focusing bracket. Therefore, the power-on setting of this solution is relatively complex, increasing the difficulty of setting the motor. In this embodiment, by arranging the focusing bracket inside the anti-shake bracket, since the focusing bracket requires a set of focusing drive components to push the focusing bracket to move along the third direction, the motor also needs a set of circuits to provide signals and power supply for the focusing drive components, that is, a set of circuits 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 setting difficulty of the motor.

[0030] Among them, the plane around which the wire of the focusing coil is wound (i.e., the winding plane) can be parallel to the third direction. At this time, the focusing coils are arranged vertically, so that the area occupied by the focusing coils in the plane perpendicular to the optical axis is relatively small, which is conducive to the miniaturization of the motor. The focusing magnetic member can include two opposite polar directions, both of which are perpendicular to the third direction. At this time, the focusing magnetic member can be arranged vertically, so as to reduce the space occupied by the focusing magnetic member in the motor and facilitate the miniaturization design of the motor.

[0031] In a possible implementation, the motor further includes four suspension wires; the suspension wires include a first fixed end and a second fixed end, and the first fixed ends of the four suspension wires are fixedly connected to the four corners of the base one by one, and the second fixed ends of the four suspension wires are connected to four positions of the anti-shake bracket one by one. In other words, it can also be considered that the suspension wires can be correspondingly fixed at the four corners of the anti-shake bracket.

[0032] 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, and the resultant force direction of the restoring forces generated by the four suspension wires is opposite to 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 movement of the anti-shake bracket, and is also conducive to maintaining the center of the anti-shake bracket in the optical axis direction, improving the reliability and control accuracy of the motor.

[0033] In a possible implementation, the motor further includes a focusing drive chip, multiple wiring lines and multiple reed switches. The focusing drive chip is fixed on the anti-shake bracket, the multiple wiring lines are embedded in the anti-shake bracket at intervals, and the multiple reed switches are fixed on the anti-shake bracket at intervals; the access ends of the multiple wiring lines are electrically connected to multiple ports of the focusing drive chip one by one, and the first connection ends of the multiple reed switches are electrically connected to the outgoing ends of the multiple wiring lines one by one; the base includes a bottom plate and four conductive members, and the conductive members are embedded in the bottom plate at intervals; the second connection ends of the multiple reed switches are electrically connected to the four conductive members through the four suspension wires one by one. Exemplarily, the wiring lines can include a first wiring line, a second wiring line, a third wiring line and a fourth wiring line, the reed switches can include a first reed switch, a second reed switch, a third reed switch and a fourth reed switch, the suspension wires can include a first suspension wire, a second suspension wire, a third suspension wire and a fourth suspension wire, and the four wiring lines respectively serve as transmission channels between the four reed switches and the four ports of the focusing drive chip. The four reed switches can respectively serve as transmission channels between the four wiring lines and the four suspension wires, so as to realize the "multi-purpose use of one object" of the suspension wires. The circuit in the motor is simple, the utilization rate of components is relatively high, which is conducive to reducing costs and realizing the miniaturization of the motor.

[0034] In a possible implementation, the base is provided with mounting holes, and the four mounting holes are located at the four corners of the base; the conductive member is provided with through holes, and the through holes of the four conductive members are arranged corresponding to the four mounting holes one by one, 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 correspondingly. In an implementation manner, by setting the suspension wires to be tightly fitted with the mounting holes and the through holes, the suspension wires are stably connected to the base and the conductive member, and the base can play a role in limiting the first fixed ends of the suspension wires, ensuring the reliability of the electrical connection between the suspension wires and the conductive member.

[0035] In a possible implementation, the motor further includes a guide rod, and the guide rod is fixed to the anti-shake bracket, or the guide rod is fixed to the focusing bracket; the focusing bracket is slidably connected to the anti-shake bracket through the guide rod, and the guide rod is made of ceramic material. Exemplarily, the number of the guide rods can be two, and the shapes, sizes, materials, etc. of the two guide rods can be the same or different. By setting the guide rod to be made of ceramic material, the manufacturing cost of the guide rod can be effectively reduced, and the mass of the guide rod can be reduced, so that the guide rod can be firmly fixed to the anti-shake bracket or the focusing bracket by means of gluing or the like, which is also beneficial to reducing the manufacturing difficulty of the motor.

[0036] In a possible implementation, the motor further includes a first buffer member, and the first buffer member is connected to the side of the focusing bracket away from the base; and / or, the motor further includes a second buffer member, and the second buffer member is connected to the side of the focusing bracket facing the base; and / or, the motor further includes a third buffer member, and the third buffer member is connected to the outer surface around the anti-shake bracket. It can be understood that the first buffer member, the second buffer member and the third buffer member can all be made of flexible materials such as liquid silicone or foam. By providing the first buffer member and / or the second buffer member, when the focusing bracket moves upward in the third direction, the impact force between the focusing bracket and the motor housing or the base can be reduced, and the lens can be prevented from being damaged or displaced due to direct collision between the focusing bracket and the motor housing or the base, improving the reliability of the motor. By providing the third buffer member, when the anti-shake bracket moves in the first direction or the second direction, the impact force between the anti-shake bracket and the motor housing can be reduced, and the lens can be prevented from being damaged or displaced due to direct collision between the anti-shake bracket and the motor housing, improving the reliability of the motor.

[0037] In a second aspect, an implementation manner of the present application further provides an imaging module. The imaging module includes a lens, an image sensor and the motor according to any one of the above, the lens is installed in 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 imaging module in this implementation manner has high imaging quality and control accuracy.

[0038] In one possible implementation, the camera module further includes a variable aperture, which is located on the light incident side of the lens. The variable aperture has an aperture hole, and the size of the aperture hole can be automatically adjusted. Light can enter the lens through the aperture hole of the variable aperture. The variable aperture is used to adjust the amount of light entering, so that the camera module can maintain a constant shooting quality under various brightness conditions.

[0039] In a third aspect, an embodiment of the present application further provides an electronic device. The electronic device includes a device housing and the camera module according to any one of the above, and the camera module is disposed in the device housing. The camera module has good shooting quality and control accuracy, which is beneficial to improving the shooting performance of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0085] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified 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 they are connected to each other and the relative positional relationship after connection remains unchanged. "Sliding connection" means that they are connected to each other and can slide relative to each other after connection. The orientation terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only references to the directions of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description 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 should not be construed as a limitation to the embodiments of the present application.

[0086] "A plurality of" means at least two. A and / or B includes three scenarios, specifically scenario A, scenario B, and scenario AB. Among them, "electrically connected" means that electrical signals can be conducted between each other. In addition, when two components are integrated through an integral molding process, it means that during 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 through additional processing (such as bonding, welding, snap connection, screw connection).

[0087] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of such features.

[0088] In addition, in the embodiments of the present application, mathematical concepts such as parallel and perpendicular are mentioned. These definitions are all based on the current technological level and are not absolute strict definitions in the mathematical sense. A small deviation is allowed, and being approximately parallel or approximately perpendicular is acceptable. For example, when A is parallel to B, it means that A is parallel to B or approximately parallel to B, and the included angle between A and B can be between 0 degrees and 10 degrees. For example, when A is perpendicular to B, it means that A is perpendicular to B or approximately perpendicular to B, and the included angle between A and B can be between 80 degrees and 100 degrees.

[0089] It can be understood that the specific embodiments described herein are only used to explain the related invention and not to limit the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0091] As Figure 1 shown, in some embodiments, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet, etc., devices with a camera function. Figure 1 The electronic device 1000 in the shown embodiment is described by taking a mobile phone as an example.

[0092] Figure 2 Yes Figure 1 Schematic cross-sectional view of a partial section of the electronic device 1000 shown in the figure taken along A-A in some embodiments.

[0093] As Figure 1 and Figure 2 shown, in some embodiments, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. Among them, 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 drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 1 and the respective drawings below. In addition, when the electronic device 1000 is a device in some other forms, the electronic device 1000 may not include the screen 300.

[0094] Among them, the device housing 200 may include a frame 201 and a rear cover 202. The rear cover 202 is fixed to the frame 201. Exemplarily, the rear cover 202 may be fixedly connected to the frame 201 by means of glue, snap connection, etc. The rear cover 202 may also be an integrally formed structure with the frame 201, that is, the rear cover 202 and the frame 201 are a single integral structure.

[0095] In some embodiments, the screen 300 may be located on the side of the frame 201 away from the rear cover 202. At this time, the screen 300 and the rear cover 202 may be located on both sides of the frame 201 respectively. The screen 300, the frame 201, and the rear cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place the components of the electronic device 1000, such as a battery, a receiver, or a microphone, etc. Among them, the screen 300 may be a flat screen or a curved screen.

[0096] Exemplarily, the camera module 100 may be located inside the electronic device 1000. The camera module 100 may be located on the side of the screen 300 facing the rear cover 202. The rear cover 202 may be provided with a light-transmitting portion 203. The shape of the light-transmitting portion 203 is not limited to the Figure 1 circular shape shown. The light-transmitting portion 203 connects the interior of the electronic device 1000 to the outside of the electronic device 1000. The light 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 collect the light entering the interior of the electronic device 1000.

[0097] Figure 3 Yes Figure 1 Schematic structural diagram of the camera module 100 in some embodiments shown in the figure Figure 4 YesFigure 3 Partial exploded view of some embodiments of the camera module 100 shown.

[0098] As Figure 3 and Figure 4 shown, 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, a variable aperture 6, and a module housing 7. Among them, the image sensor 4 is also referred to as a photosensitive chip or a photosensitive element. The image sensor 4 is used to collect ambient light and convert the image information carried by the ambient light into an electrical signal.

[0099] It can be understood that the camera module 100 may also include fewer or more structures. For example, the camera module 100 may include fewer structures. Exemplarily, 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.

[0100] It can be understood that, for the convenience of description hereinafter, it is defined that the camera module 100 has 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, 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 setting of the camera module 100 can be flexibly set according to specific actual needs.

[0101] Figure 5 is Figure 3 Partial cross-sectional view of the camera module 100 shown taken along line B-B in some embodiments.

[0102] As Figure 5 shown, the module housing 7 is fixed on the module circuit board 3 and together with the module circuit board 3 encloses an accommodation space 70. The motor 1, the lens 2, the image sensor 4, the filter holder 5a, the filter 5b, etc. can all be located in the accommodation space 70. The module housing 7 covers at least a part of the motor 1, and a part of the lens 2 can extend out of the module housing 7 through the opening of the module housing 7. The module housing 7 can be used to protect the structural components in the camera module 100.

[0103] As Figure 5 shown, the image sensor 4 can be disposed on the module circuit board 3 and is electrically connected to the module circuit board 3. At this time, signals can be transmitted between the image sensor 4 and the module circuit board 3.

[0104] Exemplarily, 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 passing hole 51a. The filter 5b is fixedly connected to the filter holder 5a. The filter 5b may be located within the light passing hole 51a. The filter 5b is also disposed opposite to the image sensor 4. The filter 5b can be used to filter infrared light, blue light, etc. in the light before entering the image sensor 4, so as to ensure that the image sensor 4 has better imaging quality.

[0105] As Figure 5 shown, the motor 1 can be fixed on 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 can be understood that in the third direction Z, the image sensor 4, the filter 5b, and the lens 2 are arranged in sequence. At this time, the image sensor 4 is located on the light-emitting side of the lens 2. The filter 5b is located between the lens 2 and the image sensor 4.

[0106] It can be understood that the lens 2 can be used to collect ambient light. Among them, the optical axis direction of the lens 2 can be parallel to the third direction Z of the imaging module 100. The optical axis direction of the lens 2 and the optical axis direction of the imaging module 100 are the same direction.

[0107] It can be understood that compared with the solution of fixing the motor 1 on the filter holder 5a, in this embodiment, by fixing the motor 1 on the module circuit board 3, the stacking of the motor 1 and the filter holder 5a in the third direction Z can be avoided, that is, the motor 1 and the filter holder 5a can be arranged staggeredly in the X-Y plane, thereby greatly reducing the height of the imaging module 100.

[0108] It can be understood that the motor 1 can be a focusing motor 1. In this way, the motor 1 can control the lens 2 to move along the third direction Z to achieve auto focus (AF). The motor 1 can also be an anti-shake motor 1. In this way, the motor 1 can control the lens 2 to move along a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the imaging module 100 collects ambient light, if the electronic device 1000 shakes in the X-Y plane due to external forces, the motor 1 can control the movement of the lens 2 in the X-Y plane to offset the shaking stroke of the lens 2 in the X-Y plane, so as to avoid or reduce the position offset of the lens 2 caused by shaking. In other words, the imaging module 100 of the present application can control the movement of the lens 2 in the X-Y plane through the motor 1 to achieve optical image stabilization (OIS) of the imaging module 100 and improve the imaging quality of the imaging module 100. The motor 1 can also be a motor 1 that integrates anti-shake and focusing. In this way, the motor 1 can both achieve auto focus by controlling the lens 2 and achieve optical image stabilization by controlling the lens 2. This embodiment will be described by taking the motor 1 as an integrated anti-shake and focusing motor 1 as an example.

[0109] As Figure 3 and Figure 4 shown, the variable aperture 6 can be located on the light incident 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.

[0110] It can be understood that the variable aperture 6 has an aperture hole 6a, and the size of the aperture hole 6a can be automatically adjusted. Light can enter the lens 2 through the aperture hole 6a of the variable aperture 6. The variable aperture 6 is used to adjust the amount of light entering, so that the imaging module 100 can maintain a constant shooting quality under various brightness conditions.

[0111] The structure of the imaging module 100 has been generally introduced above in combination with the related drawings. The structure of the motor 1 will be specifically introduced below in combination with the related drawings.

The circuit board assembly 33 may include a focusing circuit board 331, a focusing driving chip 332, a focusing sensor 333, and a focusing reinforcement member 334. In other embodiments, the circuit board assembly 33 may also not include the focusing sensor 333 and / or the focusing reinforcement member 334.

[0123] Figure 8 Yes Figure 7 Partial exploded view of the base 11 shown in some embodiments. Figure 9 Yes Figure 7 Partial cross-sectional view of the base 11 shown in some embodiments taken along C-C.

[0124] As Figure 8 And Figure 9 As shown in Figure 8 and Figure 9 , exemplarily, the base 11 may further include a plurality of conductive members 115. The conductive member 115 may include a first conductive portion 1151, a second conductive portion 1152, and an extension portion 1153.

Exemplarily, the extension portion 1153 may be in a circular ring shape.

[0125] In some embodiments, a plurality of conductive members 115 may be embedded in the base plate 111 at intervals. Exemplarily, the number of the conductive members 115 may be four. Among them, the four extension portions 1153 are respectively arranged 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.

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

[0127] Exemplarily, the base 11 may further include a first metal member 116. The first metal member 116 may include a reinforcing portion 1161 and a supporting portion 1162. The reinforcing portion 1161 may be in a frame shape and may include a first edge 1161a, a second edge 1161b, a third edge 1161c, and a fourth edge 1161d. The number of the supporting portions 1162 may be three.

In some embodiments, the reinforcing portion 1161 and the supporting portion 1162 may be an integrally formed structure.

[0128] Exemplarily, the supporting portion 1162 may include a first portion 1162a and a second portion 1162b. The second portion 1162b is connected between the first portion 1162a and the reinforcing portion 1161. The second portion 1162b is vertically arranged relative to the reinforcing portion 1161. The first portion 1162a is bent relative to the second portion 1162b and is spaced apart from the reinforcing portion 1161.

[0129] In some embodiments, the first metal part 116 is installed in the bottom plate 111. The first metal part 116 can improve the overall strength of the base 11 to avoid damage to the base 11, which is beneficial to improving the reliability of the base 11. For example, the first metal part 116 can be made of a steel sheet. Exemplarily, the first edge 1161a can be embedded in the first border area 1111, the second edge 1161b is embedded in the second border area 1112, the third edge 1161c is embedded in the third border area 1113, and the fourth edge 1161d is correspondingly embedded in the fourth border area 1114. The first support part 1163 can be embedded in the first mounting block 1121, the second support part 1164 can be embedded in the second mounting block 1122, and the third support part 1165 can be embedded in the third mounting block 1123. Exemplarily, the reinforcing part 1161 can be embedded in the bottom plate 111 and is located on the side of the support part 1162 away from the groove 113. Among them, the second part 1162b can be embedded in the corresponding mounting block 112, and the first part 1162a can be exposed relative to the corresponding groove 113. In other embodiments, the reinforcing part 1161 can also be fixed to the side of the second surface 111b away from the first surface 111a by means of adhesion or the like, and the present application does not limit this.

[0130] Exemplarily, the first conductive part 1151 can be located in the area between the first part 1162a and the reinforcing part 1161 and is spaced from both the support part 1162 and the reinforcing part 1161. The second conductive part 1152 is also spaced from the edge of the reinforcing part 1161 and is located on the side of the reinforcing part 1161 away from the first through hole 1115. At this time, the conductive part 115 and the first metal part 116 can form a three-layer structure. Exemplarily, the first layer structure is that the first part 1162a is used to enhance the structural strength of the groove 113, the second layer structure is that the first conductive part 1151 is used as an electrical transmission channel in the base 11, and the third layer structure is that the reinforcing part 1161 is used to enhance the structural strength of the bottom plate 111. By setting the first conductive part 1151 in the area between the first part 1162a and the reinforcing part 1161, the space in the bottom plate 111 can be effectively and fully utilized, which is beneficial to the miniaturization of the motor 1. In addition, by setting the conductive part 115 and the first metal part 116 to be spaced apart, it can avoid interference with the electrical transmission process of the conductive part 115 when the first metal part 116 contacts the conductive part 115, so as to ensure the reliability of the motor 1 while achieving miniaturization.

[0155] 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 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.

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 any limitations.

[0157] Exemplarily, the metal insert 216 can be embedded in the anti-shake bracket body 211. The first insert 2161a is embedded at the connection of 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 at the connection of the first side 211a and the second side 211b. The second plate 2162b is embedded in the second side 211b. The third insert 2163a is embedded at the connection of the second side 211b and the third side 211c.

[0158] In this embodiment, the metal insert 216 is embedded in the anti-shake bracket body 211 and can form an integrally molded structural member with the anti-shake bracket body 211 by means such as insert-molding. At this time, 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.

[0159] Figure 14 is Figure 6 Partial structural schematic of the motor 1 shown in some embodiments Figure 2 。

[0160] Such as Figure 14As shown, exemplarily, the first anti-shake magnetic member 222 is installed in the first installation groove 2131, the second anti-shake magnetic member 224 is installed in the second installation groove 2132, and the compensation magnetic member 232 is installed in the third installation groove 2133. At this time, the compensation magnetic member 232, the first anti-shake magnetic member 222, and the second anti-shake magnetic member 224 can be arranged in an L shape. The first anti-shake magnetic member 222 and the second anti-shake magnetic member 224 are arranged on both sides of the first side portion 211a and the second side portion 211b of the anti-shake bracket 21. The third side portion 211c of the anti-shake bracket 21 is used to arrange the compensation magnetic member 232. There may be no structural member arranged on the fourth side portion 211d of the anti-shake bracket 21, which can make full use of the three-side positions of the anti-shake bracket 21, and the volume of the remaining one side position can be minimized, thus facilitating the miniaturization of the overall motor 1.

[0161] In some embodiments, the first anti-shake magnetic member 222 has a first axis 21a. The first axis 21a can pass through the center of the first anti-shake magnetic member 222 and be parallel to the first direction Y. The second anti-shake magnetic member 224 may have a second axis 21b. The second axis 21b can pass through the center of the second anti-shake magnetic member 224 and be parallel to the second direction X. The center of the compensation magnetic member 232 is offset from both the first axis 21a and the second axis 21b. At this time, the first axis 21a does not pass through the center of the compensation magnetic member 232, and there is a distance between the center of the compensation magnetic member 232 and the first axis 21a in the first direction Y. The second axis 21b does not pass through the center of the compensation magnetic member 232, and there is a distance between the center of the compensation magnetic member 232 and the second axis 21b in the second direction X. Exemplarily, the compensation magnetic member 232 can be located on the side of the first axis 21a close to the second anti-shake magnetic member 224. In other embodiments, the compensation magnetic member 232 can also be located on the side of the first axis 21a away from the second anti-shake magnetic member 224.

[0162] In some examples, the compensation magnetic member 232 can be offset from both the first axis 21a and the second axis 21b. In this way, on the one hand, it can ensure that the center of the compensation magnetic member 232 is offset from both the first axis 21a and the second axis 21b, and on the other hand, it can increase the torque of the compensation magnetic member 232.

[0163] Exemplarily, the first anti-shake magnetic member 222 may include one or more magnets, and there can be various implementation structures for the first anti-shake magnetic member 222. For example, in some embodiments, the first anti-shake magnetic member 222 may adopt a dual-magnet scheme, such as being composed of two magnets. The two magnets are arranged in the first direction Y, and the polar directions are opposite. In some other embodiments, the first anti-shake magnetic member 222 is a Halbach magnet array. For example, the first anti-shake magnetic member 222 may include at least three magnets. Among the adjacent three magnets, the polar directions of the two magnets on the sides are opposite and perpendicular to the arrangement direction of the three magnets, and the polar direction of the magnet in the middle points from one magnet to the other. In some other embodiments, the first anti-shake magnetic member 222 may adopt a single-magnet scheme, such as being composed of one magnet, and the magnet includes two parts with opposite polar directions. The magnet can be made by a bipolar magnetization process. In the embodiments of the present application, the first anti-shake magnetic member 222 is taken as an example of a Halbach magnet array for introduction, and the present application does not limit this.

[0164] Exemplarily, the second anti-shake magnetic member 224 may include one or more magnets, and there can be various implementation structures for the second anti-shake magnetic member 224. For example, in some embodiments, the second anti-shake magnetic member 224 may adopt a dual-magnet scheme, such as being composed of two magnets. The two magnets are arranged in the second direction X, and the polar directions are opposite. In some other embodiments, the second anti-shake magnetic member 224 is a Halbach magnet array. In some other embodiments, the second anti-shake magnetic member 224 may adopt a single-magnet scheme, such as being composed of one magnet, and the magnet includes two parts with opposite polar directions. The magnet can be made by a bipolar magnetization process. In the embodiments of the present application, the second anti-shake magnetic member 224 is taken as an example of a Halbach magnet array for introduction, and the present application does not limit this.

[0165] Exemplarily, the compensation magnetic member 232 may include one or more magnets, and there can be various implementation structures for the compensation magnetic member 232. For example, in some embodiments, the compensation magnetic member 232 may adopt a dual-magnet scheme, such as being composed of two magnets. The two magnets are arranged in the first direction Y, and the polar directions are opposite. In some other embodiments, the compensation magnetic member 232 is a Halbach magnet array. In some other embodiments, the compensation magnetic member 232 may adopt a single-magnet scheme, such as being composed of one magnet, and the polar direction of the magnet is parallel to the third direction Z. In the embodiments of the present application, the compensation magnetic member 232 is taken as an example of a single magnet for introduction, and the present application does not limit this. In some examples, the length of the compensation magnetic member 232 can be less than the lengths of the first anti-shake magnetic member 222 and the second anti-shake magnetic member 224, which is beneficial to reducing the occupied space of the compensation magnetic member 232 in the anti-shake bracket 21, beneficial to reducing the size of the anti-shake bracket 21, and realizing the miniaturization of the motor 1.

[0166] Figure 15 is Figure 6 a partially exploded schematic view of the motor 1 shown in some embodiments. Figure 16 is Figure 6 a partial structural schematic of the motor 1 shown in some embodiments Figure 3 . Figure 17 is Figure 16 a partial cross-sectional schematic view of the motor 1 shown in some embodiments taken along the D-D section.

[0167] As Figure 15 , Figure 16 and Figure 17 shown, exemplarily, the anti-shake bracket 21 can be movably connected to the base 11 through the first ball group 241, the second ball group 242, and the 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 to achieve the movable connection of the anti-shake bracket 21 to the base 11. In this embodiment, the ball group 24 is used to provide support, which can reduce the frictional resistance between the balls and the anti-shake bracket 21 while ensuring sufficient support force, and improve the smoothness of the movement process of the anti-shake bracket 21 movably connected to the base 11. In addition, the ball group 24 can provide multi-point support for the anti-shake bracket 21, which is beneficial to dispersing stress, preventing the balls from deforming when being collided due to excessive force concentration in a single direction, and can improve the reliability of the support of the ball group 24 on structural parts such as the anti-shake bracket 21. In other embodiments, the motor 1 may not include the ball group 24 and include a guide shaft. The anti-shake bracket 21 can be movably connected to the base 11 through the guide shaft, and this application does not limit this. At this time, the first ball group 241 is connected to the connection between the first side portion 211a and the second side portion 211b, the second ball group 242 is connected to the connection between the second side portion 211b and the third side portion 211c, and the third ball group 243 is connected to the connection between the fourth side portion 211d and the first side portion 211a. The three ball groups 24 can form a three-point support structure, which is beneficial to reducing the number of the ball groups 24 while ensuring the bearing capacity of the ball group 24 on the anti-shake bracket 21, and reducing the manufacturing cost of the motor 1.

[0168] Exemplarily, 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. Both 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 the movement process.

[0169] Exemplarily, 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 towards one side when the three ball groups 24 are concentrated on the same side of the first axis 21a, which affects the smoothness and reliability of the movement process of the anti-shake bracket 21.

[0170] In some embodiments, the first side portion 211a corresponds to the first side region 1111, the second side portion 211b corresponds to the second side region 1112, the third side portion 211c corresponds to the third side region 1113, and the fourth side portion 211d corresponds to the fourth side region 1114. Exemplarily, the first through hole 1115 and the second through hole 2113 at least partially overlap. In other words, it can also be considered that the anti-shake bracket 21 and the base 11 are coaxially nested, which is beneficial to improving the layout compactness of the structural components in the motor 1 and can also improve the space utilization rate in the motor 1, facilitating the miniaturization of the motor 1. Exemplarily, 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 Figure 5 shown).

[0171] Exemplarily, the first anti-shake magnetic member 222 is fixed to the anti-shake bracket 21, and the first anti-shake coil 221 is arranged facing the first anti-shake magnetic member 222 for driving the anti-shake bracket 21 to move relative to the base 11 in the first direction Y. The first anti-shake magnetic member 222 and the first anti-shake coil 221 are arranged in the third direction Z. Herein, the first anti-shake coil 221 being arranged facing the first anti-shake magnetic member 222 means that the winding plane of the first anti-shake coil 221 faces the first anti-shake magnetic member 222. For example, the winding plane of the first anti-shake coil 221 can be perpendicular to the third direction Z. At this time, the first anti-shake coil 221 can be horizontally arranged, which is beneficial to reducing the size of the motor 1 in the third direction Z and realizing the miniaturization of the motor 1. Exemplarily, the first position sensor 225 (as Figure 17 shown) can be used to detect the first magnetic field change amount of the first anti-shake magnetic member 222 when the anti-shake bracket 21 moves in the first direction Y, that is, to detect the position change of the anti-shake bracket 21 in the first direction Y.

[0172] In addition, by arranging the first anti-shake coil 221 and the first anti-shake magnetic member 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 member 222 and the first anti-shake coil 221. The above magnetic gap is not affected by the movement of the anti-shake bracket 21. Therefore, the problem of rapid decline in driving force caused by the increase in the magnetic gap can be avoided, and the stability of the driving force can be ensured while having a large anti-shake driving force, which is beneficial to the anti-shake design with a large stroke.

[0173] Figure 18 is Figure 16 a partial cross-sectional schematic view of the motor 1 shown in some embodiments cut along E-E. Figure 19 is Figure 16 a partial cross-sectional schematic view of the motor 1 shown in some embodiments cut along F-F.

[0174] As shown Figure 18 in the figure, exemplarily, the second anti-shake magnetic member 224 is fixed to the anti-shake bracket 21, the second anti-shake coil 223 is arranged facing the second anti-shake magnetic member 224, and is used to drive the anti-shake bracket 21 to move relative to the base 11 along the second direction X. The second anti-shake magnetic member 224 and the second anti-shake coil 223 are arranged in the third direction Z. Among them, the second anti-shake coil 223 is arranged facing the second anti-shake magnetic member 224, which means that the winding plane of the second anti-shake coil 223 faces the second anti-shake magnetic member 224. For example, the winding plane of the second anti-shake coil 223 can be arranged perpendicular to the third direction Z. At this time, the second anti-shake coil 223 can be arranged horizontally, which is beneficial to reducing the size of the motor 1 in the third direction Z and realizing the miniaturization of the motor 1. Exemplarily, the second position sensor 226 can be used to detect the change amount of the second magnetic field of the second anti-shake magnetic member 224 when the anti-shake bracket 21 moves along the second direction X, that is, to detect the position change of the anti-shake bracket 21 in the second direction X.

[0175] In addition, by arranging the second anti-shake coil 223 and the second anti-shake magnetic member 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 member 224 and the second anti-shake coil 223. The above magnetic gap is not affected by the movement of the anti-shake bracket 21. Therefore, the problem of rapid decline of the driving force caused by the increase of the magnetic gap can be avoided, and the stability of the driving force can be ensured while having a large anti-shake driving force, which is beneficial to the anti-shake design with a large stroke.

[0176] As shown Figure 19 in the figure, exemplarily, 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. Among them, the compensation coil 231 is arranged facing the compensation magnetic member 232, which 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. At this time, the compensation coil 231 can be arranged horizontally, which is beneficial to reducing the size of the motor 1 in the third direction Z and realizing the miniaturization of the motor 1.

[0177] By arranging the compensation mechanism 23, during the movement of the anti-shake bracket 21 relative to the base 11, due to reasons such as the mechanical structure of the motor 1 itself and / or the assembly process, when the anti-shake bracket 21 translates along the first direction Y or the second direction X, the resultant moment received is not zero, and the anti-shake bracket 21 deflects in the X-Y plane, resulting in problems such as displacement of the anti-shake bracket 21 relative to the base 11 in a direction other than the movement direction. This is beneficial to improving the reliability and control accuracy of the motor 1.

[0178] Among them, the third position sensor 233 can be used to detect the change amount of the third magnetic field of the compensation magnetic member 232 when the anti-shake bracket 21 moves in the first direction Y, and obtain the deflection amount of the anti-shake bracket 21 according to the change amount of the third magnetic field and the change amount of the first magnetic field. Exemplarily, when the anti-shake bracket 21 moves in the first direction Y, the first position sensor 225 can detect the change amount of the first magnetic field of the first anti-shake magnetic member 222, and the third position sensor 233 can detect the change amount of the third magnetic field of the compensation magnetic member 232. If the anti-shake bracket 21 deflects, it will cause the displacements of the opposite sides of the anti-shake bracket 21 in the first direction Y to be different. At this time, the change amount of the first magnetic field and the change amount of the second magnetic field will not be equal, and the third position sensor 233 can obtain the deflection amount of the anti-shake bracket 21 according to the difference between the change amount of the first magnetic field and the change amount of the third magnetic field.

[0179] Exemplarily, when the anti-shake bracket 21 moves in the second direction X, the third position sensor 233 can detect the change amount of the fourth magnetic field of the compensation magnetic member 232. If the anti-shake bracket 21 deflects, it will cause the anti-shake bracket 21 to have a displacement in the first direction Y. At this time, the change amount of the fourth magnetic field will not be zero, and the deflection amount of the anti-shake bracket 21 can be obtained according to the change amount of the fourth magnetic field.

[0180] Next, taking the process that when the anti-shake bracket 21 moves relative to the base 11 in the first direction Y and the anti-shake bracket 21 moves relative to the base 11 in the second direction X, the torque generated by the friction of the ball group 24 is not zero, resulting in the anti-shake bracket 21 being offset as an example for introduction. In other embodiments, the compensation mechanism 23 can also be applied to solve the offset of the anti-shake bracket 21 caused by other reasons, such as the center of gravity and geometric center of the motor 1 not coinciding with the mechanical center between the X-axis direction and the Y-axis direction. The present application does not make specific introduction thereto. In addition, in the embodiment of the present application, the center of gravity and geometric center of the motor 1 coincide with the mechanical center between the X-axis direction and the Y-axis direction and are located on the optical axis.

[0181] Solution 1: Figure 20a It is a schematic diagram of the working state of a compensation mechanism 23 provided by an embodiment of the present application. Figure 20b It is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application.

[0182] As Figure 20a shown, exemplarily, the anti-shake bracket 21 (as Figure 15 shown) moves relative to the base 11 (as Figure 15 shown) in the positive direction X1 of the second direction (as Figure 20a the direction pointed by the solid line with an arrow in) during the process:

[0183] The anti-shake bracket 21 is subjected to the action of the first driving force F1 provided by the second anti-shake magnetic member 224. Among them, the direction of the first driving force F1 is the positive direction X1 of the second direction, the force arm of the first driving force F1 is zero, the torque M1 generated by the first driving force F1 = 0, and the first driving force F1 serves as a power source to drive the anti-shake bracket 21 to translate relative to the base 11 along the positive direction X1 of the second direction.

[0184] During the movement of the anti-shake bracket 21, it is also subjected to the action of 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 force arms of the first friction force f1, the second friction force f2, and the third friction force f3 are all L1, and 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, and L1 is not zero. Figure 20a Where 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 rotate counterclockwise is defined as a positive torque, and vice versa as a negative torque. Then, the first rotational torque M2 generated by the ball group 24 that the anti-shake bracket 21 receives during the movement is M2=(f1×L1)+(f3×L1)-(f2×L1).

[0185] When M2≠0, it will drive the anti-shake bracket 21 to rotate in the X-Y plane, so that the anti-shake bracket 21 cannot drive the lens 2 to reach the preset position in the second direction X to achieve the anti-shake function of the motor 1, and it will also cause the lens 2 to have an additional displacement in the first direction Y, affecting the control accuracy and reliability of the motor 1.

[0186] It can be understood that in the embodiment of the present application, since the first anti-shake magnetic member 222 is provided on one side of the first side portion 211a (as Figure 15 shown), and on the opposite side, the third side portion 211c (as Figure 15 shown) does not have the first anti-shake magnetic member 222 provided therein, the pressure magnitudes of the opposite sides of the anti-shake bracket 21 on the base 11 in the first direction Y are different, so that the friction force magnitudes provided by the ball group 24 on the opposite sides of the anti-shake bracket 21 in the first direction Y are also inconsistent. The sum of f1 and f3 will be greater than f2, then the first rotational torque M2 can be greater than 0, and the first rotational 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, the motor 1 may also deflect due to uneven forces on the opposite sides of the anti-shake bracket 21 caused by other reasons such as assembly errors of internal structural members. The present application does not limit this.

[0187] Exemplarily, in the embodiments of the present application, by providing a compensation mechanism 23 (such as Figure 15 shown), the anti-shake bracket 21 is also affected by a first acting force f41 provided by the compensation magnetic member 232, which is used to generate a first compensation torque M3 to compensate the first rotational torque M2, so that the resultant torque M4 received by the anti-shake bracket 21 can be maintained at zero, ensuring that the anti-shake bracket 21 is affected by the first driving force F1 to drive the lens 2 (such as Figure 5 shown) to translate in its preset direction (the positive direction X1 of the second direction) without deflection. Among them, the lever arm of the first acting force f41 is L2, 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.

[0188] By adjusting the magnitude and direction of the current of the compensation coil 231 (such as Figure 15 shown) of the compensation mechanism 23, the magnitude of the first compensation torque M3 is made equal to the magnitude of the first rotational torque M2, and the first compensation torque M3 is a negative torque, opposite to the acting 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 to balance and counteract the possible deflection caused by the influence of the first rotational torque M2 received by the anti-shake bracket 21, which can effectively improve the control accuracy and reliability of the motor 1. At this time, the acting direction of the first acting force f41 can be along the negative direction Y2 of the first direction, so that the anti-shake bracket 21 can rotate clockwise relative to the base 11 (M3 < 0). In other embodiments, the direction of the first acting force f41 can also form an angle with the negative direction Y2 of the first direction, or when the relative position between the compensation mechanism 23 and the center of the anti-shake bracket 21 changes, the direction of the first acting force f41 can also be along the positive direction Y1 of the first direction, or along the second direction X, which can be set as needed, and the present application does not limit this.

[0189] Such as Figure 20b shown, exemplarily, during the process that the anti-shake bracket 21 (such as Figure 15 shown) moves relative to the base 11 (such as Figure 15 shown) along the positive direction Y1 of the first direction (such as Figure 20b the direction indicated by the solid line with an arrow in

[0190] The anti-shake bracket 21 is affected by a second driving force F2 provided by the first anti-shake magnetic member 222. Among them, the direction of the second driving force F2 is the positive direction Y1 of the first direction, the lever arm of the second driving force F2 is zero, the torque M5 generated by the second driving force F2 = 0, and the second driving force F2 is used as a power source to drive the anti-shake bracket 21 to translate relative to the base 11 along the positive direction Y1 of the first direction.

[0191] During the movement of the anti-shake bracket 21, it is also affected by the first frictional force f1 between the anti-shake bracket 21 and the first ball group 241, the second frictional force f2 between the anti-shake bracket 21 and the second ball group 242, and the third frictional force f3 between the anti-shake bracket 21 and the third ball group 243. Among them, the lever arms of the first frictional force f1, the second frictional force f2, and the third frictional force f3 are all L3. 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, and L3 is not zero. Figure 20b Where f12 represents the resultant force of the first frictional force f1 and the second frictional force f2. It can be understood that in the embodiment of the present application, the torque that causes the anti-shake bracket 21 to rotate counterclockwise is defined as the positive torque, and vice versa as the negative torque. Then, the second rotational torque M6 generated by the ball group 24 received by the anti-shake bracket 21 during the movement is M6 = (f3 × L3) - (f1 × L3) - (f2 × L3).

[0192] When M6 ≠ 0, it will drive the anti-shake bracket 21 to rotate within the X-Y plane, so that the anti-shake bracket 21 cannot drive the lens 2 to reach the preset position in the first direction Y to achieve the anti-shake function of the motor 1, and it will also cause the lens 2 to generate an additional displacement in the second direction X, affecting the control accuracy and reliability of the motor 1.

[0193] In the embodiment of the present application, since the second anti-shake magnetic member 224 is provided at the second side portion 211b (as Figure 15 shown), and on the opposite side thereof, the fourth side portion 211d (as Figure 15 shown) does not have the second anti-shake magnetic member 224 provided therein, the pressure magnitudes on the opposite sides of the anti-shake bracket 21 on the second direction X with respect to the base 11 are different, which will cause the frictional force magnitudes provided by the ball group 24 on the opposite sides of the anti-shake bracket 21 in the second direction X to be inconsistent. The sum of f1 and f2 will be greater than f3, then the second rotational torque M6 can be less than 0, and the second rotational 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, the motor 1 may also deflect due to uneven forces on the opposite sides of the anti-shake bracket 21 caused by other reasons such as assembly errors of internal structural members. The present application does not limit this.

[0194] Exemplarily, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 is further subjected to the second acting force f42 provided by the compensation magnetic member 232 to generate a second compensation torque M7 for compensating the second rotational torque M6, so that the resultant torque M4 received by the anti-shake bracket 21 can be restored to zero, ensuring that the anti-shake bracket 21 can drive the lens 2 to translate in its preset direction (the positive direction Y1 of the first direction) without deflection. Wherein, the arm of force of the second acting force f42 is L2, and L2 is the distance from the center of the compensation magnetic member 232 in the second direction X to the center of the anti-shake bracket 21, and L2 is not zero, and M7 = f42 × L2.

[0195] By adjusting the magnitude and direction of the current in the compensation coil 231 in the compensation mechanism 23, the magnitude of the second compensation torque M7 is made equal to the magnitude of the second rotational torque M6, and the second compensation torque M7 is a positive torque, opposite to the acting 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 to balance and eliminate the possible deflection of the anti-shake bracket 21 affected by the second rotational torque M6, so that the anti-shake bracket 21 maintains a translational motion, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the acting direction of the second acting force f42 can be along the positive direction Y1 of the first direction, so that the anti-shake bracket 21 can rotate counterclockwise relative to the base 11 (M7>0). In other embodiments, the direction of the second acting force f42 can also form an angle with the positive direction Y1 of the first direction, or when the relative position of the center of the compensation mechanism 23 and the anti-shake bracket 21 changes, the direction of the second acting force f42 can also be along the second direction X, which can be set as needed, and the present application does not limit this.

[0196] In the foregoing embodiment, as Figure 15 shown, the compensation coil 231 is installed in the third border area 1113 and is disposed close to the second ball group 242. At this time, the compensation magnetic member can be located at the upper right of the center of the anti-shake bracket 21. In some other embodiments, the compensation coil 231 can also be installed at other positions. At this time, correspondingly, the relative position of the compensation magnetic member 232 relative to the center of the anti-shake bracket 21 will change, and the acting direction and the magnitude and direction of the arm of force of the first acting force f41 or / and the second acting force f42 will also change. Exemplarily, the compensation coil 231 can also be installed in the third border area 1113 and is disposed away from the second ball group 242, or the compensation coil 231 can also be installed in the fourth border area 1114 and is disposed away from the third ball group 243, or the compensation coil 231 can also be installed in the fourth border area 1114 and is disposed close to the third ball group 243.

[0197] The following embodiments may include most of the technical solutions of the foregoing embodiments. The main description focuses on the differences between the two, and most of the identical content will not be elaborated.

[0198] Solution 2: Figure 21a It is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application. Figure 21b It is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application.

[0199] Figure 21a and Figure 21b The motor 1 shown in Figure 20a and Figure 20b is different from the motor 1 shown in Figure 21a and Figure 21b In the motor 1 shown in

[0200] As Figure 21a shown, exemplarily, during the process in which the anti-shake bracket 21 (as shown in Figure 15 ) moves in the positive direction X1 of the second direction (the direction indicated by the solid line with an arrow in Figure 15 ) relative to the base 11 (as shown in Figure 21a ):

[0201] The anti-shake bracket 21 is subjected to the action in the direction of the first driving force F1 in the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 = 0; the first rotational torque M2 generated by the ball group 24 during the movement of the anti-shake bracket 21, and the first rotational torque M2 = (f1 × L1) + (f3 × L1) - (f2 × L1), and M2 > 0.

[0202] In the embodiment of the present application, by setting the compensation mechanism 23, the anti-shake bracket 21 is further subjected to the action of the first acting force f41 provided by the compensation magnetic member 232, which is used to generate the first compensation torque M3 to compensate the first rotational torque M2, so that the resultant torque M4 received by the anti-shake bracket 21 can be maintained at zero.

[0203] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the first compensation torque M3 is made equal to the magnitude of the first rotational torque M2, and the first compensation torque M3 is a negative torque, opposite to the acting 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, so as to balance and eliminate the deflection that may be caused by the influence of the first rotational torque M2 received by the anti-shake bracket 21, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the first acting force f41 is L2, and 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. M3 = f41 × L2. To enable the anti-shake bracket 21 to rotate clockwise relative to the base 11 (M3 < 0), the acting direction of the first acting force f41 can be along the positive direction Y1 of the first direction.

[0204] As Figure 21b shown, exemplarily, the anti-shake bracket 21 (as Figure 15 shown) relative to the base 11 (as Figure 15 shown) moves along the positive direction Y1 of the first direction (as Figure 21b indicated by the solid arrowed line in):

[0205] The anti-shake bracket 21 is subjected to the action of the second driving force F2 along the positive direction Y1 of the first direction, and the torque M5 generated by the second driving force F2 = 0; the second rotational torque M6 generated by the ball group 24 received by the anti-shake bracket 21 during the movement process is M6 = (f3 × L3) - (f1 × L3) - (f2 × L3), and M6 < 0.

[0206] Exemplarily, in the embodiment of the present application, by providing the compensation mechanism 23, the anti-shake bracket 21 is further subjected to the action of the second acting force f42 provided by the compensation magnetic member 232, generating the second compensation torque M7, so as to compensate the second rotational torque M6, so that the resultant torque M4 received by the anti-shake bracket 21 can be maintained at zero.

[0207] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the second compensation torque M7 is made equal to the magnitude of the second rotational torque M6, and the second compensation torque M7 is a positive torque, opposite in direction of action to 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, so as to balance and eliminate the deflection that may be caused by the influence of the second rotational torque M6 received by the anti-shake bracket 21, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the second acting force f42 is L2, and 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. M7 = f42 × L2. To enable the anti-shake bracket 21 to rotate counterclockwise relative to the base 11 (M7 > 0), the direction of action of the second acting force f42 can be along the negative direction Y2 of the first direction. In other embodiments, the direction of the second acting force f42 may also form an angle with the negative direction Y2 of the first direction.

[0208] Solution Three: Figure 22a is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application. Figure 22b is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application.

[0209] Figure 22a and Figure 22b The shown motor 1 and Figure 20a and Figure 20b The difference between the shown motor 1 is that Figure 22a and Figure 22b In the shown motor 1, the compensation coil 231 can also be installed in the fourth border area 1114 and is arranged away from the third ball group 243, and the compensation magnetic member 232 is located at the upper left of the center of the anti-shake bracket 21.

[0210] As Figure 22a shown, exemplarily, during the process in which the anti-shake bracket 21 (as shown in Figure 15 ) moves relative to the base 11 (as shown in Figure 15 ) along the positive direction X1 of the second direction (as shown by the arrow of the solid line in Figure 22a ):

[0211] The anti-shake bracket 21 is subjected to the action in the direction of the first driving force F1 along the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 = 0; the anti-shake bracket 21 is subjected to the first rotational torque M2 generated by the ball group 24 during the movement, and the first rotational torque M2 = (f1 × L1) + (f3 × L1) - (f2 × L1), and M2 > 0.

[0212] In the embodiment of the present application, by providing a compensation mechanism 23, the anti-shake bracket 21 is also subjected to the action of a third acting force f43 provided by the compensation magnetic member 232, which is used to generate a third compensation torque M8 to compensate the first rotation torque M2, so that the resultant torque M4 received by the anti-shake bracket 21 can be maintained at zero.

[0213] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the third compensation torque M8 is made equal to the magnitude of the first rotation torque M2, and the third compensation torque M8 is a negative torque, opposite to the acting direction of the first rotation torque M2. The third compensation torque M8 is used to drive the anti-shake bracket 21 to rotate clockwise relative to the base 11 to balance and eliminate the deflection that may be caused by the influence of the first rotation torque M2 received by the anti-shake bracket 21, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the third acting force f43 is L4, and L4 is the distance from the center of the compensation magnetic member 232 in the first direction Y to the center of the anti-shake bracket 21. M8 = f43 × L4. To make the anti-shake bracket 21 rotate clockwise relative to the base 11 (M8 < 0), the acting direction of the third acting force f43 can be along the negative direction X2 of the second direction.

[0214] As Figure 22b shown, by way of example, during the process in which the anti-shake bracket 21 (as Figure 15 shown) moves relative to the base 11 (as Figure 15 shown) in the positive direction Y1 of the first direction (as Figure 22b indicated by the arrowed solid line in

[0215] The anti-shake bracket 21 is subjected to the action of a second driving force F2 in the positive direction Y1 of the first direction, and the torque M5 generated by the second driving force F2 = 0; the second rotation torque M6 generated by the ball group 24 received by the anti-shake bracket 21 during the movement is M6 = (f3 × L3) - (f1 × L3) - (f2 × L3), and M6 < 0.

[0216] By way of example, in the embodiment of the present application, by providing a compensation mechanism 23, the anti-shake bracket 21 is also subjected to the action of a fourth acting force f44 provided by the compensation magnetic member 232, generating a fourth compensation torque M9 to compensate the second rotation torque M6, so that the resultant torque M4 received by the anti-shake bracket 21 can be maintained at zero.

[0217] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the fourth compensation torque M9 is made equal to the magnitude of the second rotational torque M6, and the fourth compensation torque M9 is a positive torque, opposite in direction of action to the second rotational torque M6. The fourth compensation torque M9 is used to drive the anti-shake bracket 21 to rotate counterclockwise relative to the base 11, so as to balance and eliminate the possible deflection of the anti-shake bracket 21 caused by the influence of the second rotational torque M6, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the fourth acting force f44 is L4, and L4 is the distance from the center of the compensation magnetic member 232 to the center of the anti-shake bracket 21 in the first direction Y. M9 = f44 × L4. To enable the anti-shake bracket 21 to rotate counterclockwise relative to the base 11 (M9 > 0), the direction of action of the fourth acting force f44 can be along the positive direction X1 of the second direction. In other embodiments, the direction of the fourth acting force f44 may also form an angle with the positive direction X1 of the second direction.

[0218] Solution Four: Figure 23a It is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application. Figure 23b It is a schematic diagram of another working state of the compensation mechanism 23 provided by an embodiment of the present application.

[0219] Figure 23a and Figure 23b The shown motor 1 and Figure 20a and Figure 20b The difference between the shown motor 1 is that Figure 23a and Figure 23b In the shown motor 1, the compensation coil 231 can also be installed in the fourth border area 1114 and is arranged close to the third ball group 243, and the compensation magnetic member 232 is located at the lower left of the center of the anti-shake bracket 21.

[0220] As Figure 23a shown, exemplarily, during the process of the anti-shake bracket 21 (as shown in Figure 15 ) moving relative to the base 11 (as shown in Figure 15 ) along the positive direction X1 of the second direction (as shown by the arrow direction of the solid line in Figure 23a ):

[0221] The anti-shake bracket 21 will be affected by the direction of the first driving force F1 along the positive direction X1 of the second direction, and the torque M1 generated by the first driving force F1 = 0; the anti-shake bracket 21 is affected by the first rotational torque M2 generated by the ball group 24 during the movement, and the first rotational torque M2 = (f1 × L1) + (f3 × L1) - (f2 × L1), and M2 > 0.

[0222] In the embodiment of the present application, by providing a compensation mechanism 23, the anti-vibration bracket 21 is also subjected to the action of a third acting 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 received by the anti-vibration bracket 21 can be maintained at zero.

[0223] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the third compensation torque M8 is made equal to the magnitude of the first rotational torque M2, and the third compensation torque M8 is a negative torque, opposite to the acting direction of the first rotational torque M2. The third compensation torque M8 is used to drive the anti-vibration bracket 21 to rotate clockwise relative to the base 11, so as to balance and eliminate the deflection that may be caused by the influence of the first rotational torque M2 received by the anti-vibration bracket 21, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the third acting force f43 is L4, and L4 is the distance from the center of the compensation magnetic member 232 in the first direction Y to the center of the anti-vibration bracket 21. M8 = f43 × L4. To enable the anti-vibration bracket 21 to rotate clockwise relative to the base 11 (M8 < 0), the acting direction of the third acting force f43 can be along the positive direction X1 of the second direction.

[0224] As Figure 23b shown, exemplarily, during the process in which the anti-vibration bracket 21 (as Figure 15 shown) moves relative to the base 11 (as Figure 15 shown) along the positive direction Y1 of the first direction (as Figure 23b indicated by the solid line with an arrow in

[0225] The anti-vibration bracket 21 is subjected to the action of a second driving force F2 along the positive direction Y1 of the first direction, and the torque M5 generated by the second driving force F2 = 0; the second rotational torque M6 generated by the ball group 24 during the movement of the anti-vibration bracket 21 = (f3 × L3) - (f1 × L3) - (f2 × L3), and M6 < 0.

[0226] Exemplarily, in the embodiment of the present application, by providing a compensation mechanism 23, the anti-vibration bracket 21 is also subjected to the action of a fourth acting force f44 provided by the compensation magnetic member 232, generating a fourth compensation torque M9 to compensate the second rotational torque M6, so that the resultant torque M4 received by the anti-vibration bracket 21 can be maintained at zero.

[0227] By adjusting the magnitude and direction of the current in the compensation coil 231, the magnitude of the fourth compensation torque M9 is made equal to the magnitude of the second rotational torque M6, and the fourth compensation torque M9 is a positive torque, opposite in direction of action to the second rotational torque M6. The fourth compensation torque M9 is used to drive the anti-shake bracket 21 to be able to rotate counterclockwise relative to the base 11, so as to balance and eliminate the deflection that may be caused by the influence of the second rotational torque M6 received by the anti-shake bracket 21, which is beneficial to improving the control accuracy and reliability of the motor 1. At this time, the lever arm of the fourth acting force f44 is L4, and L4 is the distance from the center of the compensation magnetic member 232 to the center of the anti-shake bracket 21 in the first direction Y. M9 = f44 × L4. To enable the anti-shake bracket 21 to rotate counterclockwise relative to the base 11 (M9>0), the direction of action of the fourth acting force f44 can be along the negative direction X2 of the second direction. In other embodiments, the direction of the fourth acting force f44 may also form an angle with the negative direction X2 of the second direction.

[0228] Figure 24 Yes Figure 6 Schematic diagram of the assembly structure of the circuit board assembly 33 and the focusing coil 321 shown.

[0229] As Figure 24 As shown, in some embodiments, the focusing drive chip 332 and the focusing sensor 333 of the circuit board assembly 33 are both fixed on the focusing circuit board 331 and are both electrically connected to the focusing circuit board 331. The focusing coil 321 is fixed on the focusing circuit board 331 and is electrically connected to the focusing circuit board 331. It can be understood that the input end and the output end of the focusing coil 321 can form a current loop with the focusing drive chip 332 through the focusing circuit board 331. At this time, the focusing drive chip 332 can control the current situation of the focusing coil 321 (such as whether to conduct current or the magnitude of the current when conducting current, etc.) through the focusing circuit board 331. Exemplarily, the focusing coil 321 can be arranged around the focusing drive chip 332 and the focusing sensor 333. In this way, the focusing drive chip 332 and the focusing sensor 333 can effectively utilize the inner space of the focusing coil 321, thereby greatly improving the space utilization rate of the motor 1.

[0230] Exemplarily, the focusing sensor 333 is used to achieve position detection, and the focusing sensor 333 can adopt a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0231] Exemplarily, the focusing reinforcement member 334 can be fixed on the side of the focusing circuit board 331 facing away from the focusing coil 321, and is used to increase the structural strength of the circuit board assembly 33 and reduce the risk of deformation of the focusing circuit board 331. It can be understood that the position, size and shape of the focusing reinforcement member 334 are not specifically limited in this embodiment.

[0232] Figure 25 Yes Figure 6 Partial structural schematic of the motor 1 in some embodiments as shown Figure 4 .

[0233] As Figure 24 and Figure 25 shown, exemplarily, the circuit board assembly 33 is installed in the fourth installation groove 2134 of the anti-shake bracket 21 to be fixed to the anti-shake bracket 21. At this time, the focusing coil 321 is fixed to the anti-shake bracket 21 through the focusing circuit board 331. It can be understood that at least part of the circuit board assembly 33 is located in the fourth installation groove 2134, making the structural arrangement of the circuit board assembly 33 and the anti-shake bracket 21 compact, which is beneficial to improving the space utilization rate.

[0234] Exemplarily, both the focusing circuit board 331 and the focusing reinforcement 334 of the circuit board assembly 33 can be fixed in the fourth installation groove 2134 by means of glue or the like.

[0235] Figure 26 Yes Figure 6 Exploded view of the focusing bracket 31 from another perspective as shown

[0236] As Figure 26 shown, in some embodiments, the focusing bracket 31 can be generally in a frame shape, and the focusing bracket 31 has a third through hole 311. The focusing bracket 31 is provided with a fifth installation groove 312, a third sliding groove 313 and a fourth sliding groove 314. Among them, the openings of the fifth installation groove 312, the third sliding groove 313 and the fourth sliding groove 314 can all be arranged facing away from the third through hole 311.

[0237] Exemplarily, the third sliding groove 313 and the fourth sliding groove 314 can be located on both sides of the fifth installation groove 312. The extending directions of the third sliding groove 313 and the fourth sliding groove 314 can be parallel to the third direction Z.

[0238] It can be understood that the third through hole 311 of the focusing bracket 31 is used for installing the lens 2 (as Figure 5 shown). Exemplarily, the central axis of the focusing bracket 31 is parallel to the optical axis of the lens 2.

[0239] Figure 27 Yes Figure 6 Partial structural schematic of the motor 1 in some embodiments as shown Figure 5 .

[0240] As Figure 26 and Figure 27 shown, in some embodiments, the focusing magnetic member 322 can be installed in the fifth installation groove 312 of the focusing bracket 31 to be fixed to the focusing bracket 31.

[0241] Exemplarily, the focusing magnetic member 322 may include one or more magnets, and there can be various implementation structures of the focusing magnetic member 322. For example, in some embodiments, the focusing magnetic member 322 may adopt a dual-magnet solution, such as being composed of two magnets. The two magnets are arranged in the first direction Y, and the polar directions are opposite. In other embodiments, the focusing magnetic member 322 is a Halbach magnet array. In other embodiments, the focusing magnetic member 322 may adopt a single-magnet solution, such as being composed of one magnet, and the magnet includes two parts with opposite polar directions. The magnet can be made by a bipolar magnetization process. In the embodiments of the present application, the focusing magnetic member 322 is taken as an example of a Halbach magnet array for introduction, and the present application is not limited thereto.

[0242] As Figure 26 and Figure 27 shown, in some embodiments, the focusing bracket 31 may include a focusing bracket body 31a and a focusing magnetic conduction member 31b. The focusing magnetic conduction 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 conduction member 31b can form an integrally molded structural member with the focusing bracket body 31a by means of insert-molding or the like. At this time, the focusing magnetic conduction member 31b is embedded in the focusing bracket 31. In other implementation manners, the focusing magnetic conduction 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 conduction member 31b can be fixed to the focusing bracket body 31a by bonding or the like, and the focusing magnetic member 322 can be fixed to the focusing magnetic conduction member 31b by bonding or the like.

[0243] Figure 28 is Figure 6 a partial exploded view of the structure of the motor 1 in some embodiments as shown. Figure 29 is Figure 6 a partial structural schematic diagram of the motor 1 in some embodiments as shown Figure 6 .

[0244] As Figure 28 and Figure 29 shown, exemplarily, the focusing bracket 31 is installed inside 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 improving the layout compactness of the structural members in the motor 1 and can also improve the space utilization rate in the motor 1, facilitating the miniaturization of the motor 1.

[0245] In some embodiments, the focusing magnetic member 322 is disposed opposite to the focusing coil 321. At this time, the third chute 313 is correspondingly disposed with the first chute 2141, and the fourth chute 314 is correspondingly disposed with the second chute 2142. Exemplarily, the number of guide rods 34 may be two. The two guide rods 34 include a first guide rod 341 and a second guide rod 342. A part of the first guide rod 341 is located in the first chute 2141, and another part of the first guide rod 341 is located in the third chute 313. A part of the second guide rod 342 is located in the second chute 2142, and another part of the second guide rod 342 is located in the fourth chute 314. Exemplarily, the shapes, sizes, materials, etc. of the two guide rods 34 may be the same or different. In the embodiments of the present application, the length of the first guide rod 341 in the third direction Z is greater than that of the second guide rod 342 as an example for introduction.

[0246] It can be understood that the focusing bracket 31 can be slidably connected to the anti-shake bracket 21 through the first guide rod 341 and the second guide rod 342. The relative sliding direction of the two is parallel to the guiding direction of the guide rod 34, that is, the third direction Z. In other embodiments, the focusing bracket 31 can also be slidably connected to the anti-shake bracket 21 through balls. The arrangement direction of the plurality of balls is the guiding direction thereof.

[0247] In some embodiments, the guide rod 34 is made of a ceramic material. By setting the guide rod 34 to be made of a ceramic material, the manufacturing cost of the guide rod 34 can be effectively reduced, and the mass of the guide rod 34 can be reduced, so that the guide rod 34 can be firmly fixed to the anti-shake bracket 21 or the focusing bracket 31 by means of gluing or the like, which is also beneficial to reducing the manufacturing difficulty of the motor 1.

[0248] In some embodiments, the fit between the guide rod 34 and the focusing bracket 31 includes a tight fit and a loose fit to reduce the assembly difficulty. For example, as Figure 24 shown, in the third chute 313 and the fourth chute 314 of the focusing bracket 31, there are included at least one "V"-shaped groove and at least one "U"-shaped groove or "L"-shaped groove. When the "V"-shaped groove is fitted with the guide rod 34, the side wall of the "V"-shaped groove contacts the guide rod 34 to achieve a tight fit. For example, the third chute 313 is a "V"-shaped groove. When the "U"-shaped groove or "L"-shaped groove is fitted with the guide rod 34, the wall of the "U"-shaped groove or "L"-shaped groove contacts the guide rod 34 to achieve a loose fit. For example, the third chute 313 can be a "V"-shaped groove, a tight fit is achieved between the first guide rod 341 and the third chute 313, the fourth chute 314 is an "L"-shaped groove, and a loose fit is achieved between the second guide rod 342 and the fourth chute 314.

[0249] It can be understood that in some other embodiments, there may be other implementation solutions for the tight fit and loose fit design between the guide rod 34 and the focusing bracket 31 or the anti-shake bracket 21, and the embodiments of the present application do not make strict limitations thereon.

[0250] Figure 30 is Figure 29 A partial cross-sectional view of the motor 1 shown in some embodiments taken along G-G.

[0251] As Figure 30 shown, the focusing coil 321 is fixed to the anti-shake bracket 21, the focusing magnetic member 322 is fixed to the focusing bracket 31, the focusing coil 321 is arranged facing the focusing magnetic member 322, and is used to drive the focusing bracket 31 to move relative to the anti-shake bracket 21 along the third direction Z. When the focusing bracket 31 moves relative to the anti-shake bracket 21 along the third direction Z, the focusing bracket 31 can drive the lens 2 mounted thereon (as Figure 5 shown) to move along the third direction Z. At this time, the motor 1 can achieve the focusing function. Among them, the focusing coil 321 is arranged facing the focusing magnetic member 322, which means that the winding plane of the focusing coil 321 faces the focusing magnetic member 322. Exemplarily, the focusing sensor 333 fixed to the focusing circuit board 331 can be used to detect the position change of the focusing bracket 31 in the third direction Z.

[0252] 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 member 322 and the focusing coil 321. The above magnetic gap is not affected by the movement of the focusing bracket 31. Therefore, the problem of rapid decline in driving force caused by the increase of the magnetic gap can be avoided, so as to ensure that the focusing driving force of the motor 1 is relatively large and the driving force is relatively stable, which is beneficial to the large-stroke design of the focusing function of the motor 1.

[0253] The focusing driving mechanism 32, the compensation mechanism 23, the first anti-shake driving mechanism 22a and the second anti-shake driving mechanism 22b of the motor 1 are all moving magnet designs. The driving of the motor 1 in the first direction Y, the second direction X and the third direction Z is controlled separately by a set of driving components (including coils and magnetic members). Among them, during the process of the focusing bracket 31 of the motor 1 moving relative to the anti-shake bracket 21 along the third direction Z for autofocusing, the relative position between the anti-shake bracket 21 and the base 11 is not affected, and the magnetic gap width of the first anti-shake driving mechanism 22a, the second anti-shake driving mechanism 22b and the compensation mechanism 23 is not likely to change. Similarly, during the process of the anti-shake bracket 21 moving relative to the base 11 along the first direction Y and / or the second direction X for optical anti-shake, the focusing bracket 31 moves with the anti-shake bracket 21, and their relative positions are not affected, and the magnetic gap width of the focusing driving mechanism 32 is not likely to change. Therefore, the focusing driving mechanism 32 of the motor 1 is decoupled from the first anti-shake driving mechanism 22a, the second anti-shake driving mechanism 22b and the compensation mechanism 23, and they do not interfere with each other during the movement process, which is beneficial to ensuring the driving accuracy of the motor 1.

[0254] In addition, since the focusing bracket 31 is located inside the anti-shake bracket 21, the focusing coil 321 is fixed to the anti-shake bracket 21, and the focusing magnetic member 322 is fixed to the focusing bracket 31, the mover assembly of the optical anti-shake of the motor 1 wraps the mover assembly of the focusing. It can be understood that when the focusing bracket 31 is located inside the anti-shake bracket 21, the anti-shake bracket 21 can be arranged around the focusing bracket 31. The surrounding can be that the anti-shake bracket 21 is arranged around the focusing bracket 31 for one week, or a part of the anti-shake bracket 21 is arranged around the focusing bracket 31. In this embodiment, the anti-shake bracket 21 is in a ring shape. At this time, the anti-shake bracket 21 is arranged around the focusing bracket 31.

[0255] It can be understood that in some solutions, the anti-shake bracket 21 is located inside the focusing bracket 31. At this time, when the camera module 100 needs to focus, the focusing bracket 31 needs to drive the anti-shake bracket 21 and the lens 2 to move along the third direction Z. In this way, the weight of the mover formed by the focusing bracket 31, the anti-shake bracket 21 and the lens 2 is relatively heavy, so that the focusing drive mechanism 32 needs to increase its volume to improve the driving force. Therefore, this setting is not conducive to the lightweight and miniaturized design of the motor 1. In this embodiment, by arranging the focusing bracket 31 inside the anti-shake bracket 21. At this time, when the camera module 100 needs to focus, the focusing bracket 31 needs to drive the lens 2 to move along the third direction Z. In this way, the mover in the focusing process of this embodiment can omit the anti-shake bracket 21, that is, the weight of the mover formed by the focusing bracket 31 and the lens 2 is relatively light, which is conducive to the miniaturized setting of the focusing drive mechanism 32. The motor 1 of this embodiment can achieve lightweight and miniaturized settings.

[0256] It can be understood that compared with the solution where the anti-shake bracket 21 is inside the focusing bracket 31, at least two anti-shake drive components are required for the anti-shake bracket 21 to push the anti-shake bracket 21 to move in the X-Y plane. In this way, the motor 1 also needs to arrange at least two sets of circuits to provide signals and power supply for the anti-shake drive components. And at least two sets of circuits need to pass through the focusing bracket 31. Therefore, the power-on setting of this solution is relatively complex, which increases the difficulty of setting the motor 1. In this embodiment, by arranging the focusing bracket 31 inside the anti-shake bracket 21, since the focusing bracket 31 requires a set of focusing drive mechanism 32 to push the focusing bracket 31 to move along the third direction Z, the motor 1 also needs a set of circuits to provide signals and power supply for the focusing drive mechanism 32, that is, a set of circuits needs to pass through the anti-shake bracket 21. Therefore, the power-on solution of the scheme of this embodiment is relatively simple, which can greatly reduce the setting difficulty of the motor 1.

[0257] Such as Figure 30As shown, the winding plane of the focusing coil 321 can be parallel to the third direction Z. At this time, the focusing coil 321 is arranged vertically, so that the area occupied by the focusing coil 321 in the X-Y plane is relatively small, which is conducive to the miniaturization of the motor 1. The focusing magnetic member 322 can include two opposite polar directions, both of which are perpendicular to the third direction Z. At this time, the focusing magnetic member 322 can be arranged vertically, so as to reduce the space occupied by the focusing magnetic member 322 in the X-Y plane, facilitating the miniaturization design of the motor 1.

[0258] Figure 31 is Figure 6 a partial exploded schematic view of the motor 1 shown in some embodiments. Figure 32 is Figure 31 a partial structural schematic of the motor 1 shown in some embodiments Figure 7 .

[0259] As Figure 31 and Figure 32 shown, in some embodiments, the number of the reed pieces 13 can be four. The four reed pieces 13 can include a first reed piece 131, a second reed piece 132, a third reed piece 133, and a fourth reed piece 134. The arrangement plane of the four reed pieces 13 can be perpendicular to the third direction Z and is located on the side of the anti-shake bracket 21 facing away from the bottom plate 111. Exemplarily, the first reed piece 131 can include a first connection end 13a, a second connection end 13b, and a third connection end 13c that are connected in sequence. Each part of the first reed piece 131 can be bent multiple times. In this way, the elastic coefficient of the first reed piece 131 can be effectively reduced. The second reed piece 132, the third reed piece 133, and the fourth reed piece 134 can also respectively include a first connection end 13a, a second connection end 13b, and a third connection end 13c. The positions of the first connection end 13a, the second connection end 13b, and the third connection end 13c in the corresponding second reed piece 132, third reed piece 133, or fourth reed piece 134 can refer to the positional relationship of the first connection end 13a, the second connection end 13b, and the third connection end 13c in the first reed piece 131 above, and the present application will not elaborate on this.

[0260] Exemplarily, the first connection ends 13a of the four reed pieces 13 are respectively arranged corresponding to the four corners of the anti-shake bracket 21. The second connection ends 13b of the four reed pieces 13 are all arranged corresponding to the second side portion 211b of the anti-shake bracket 21 and are spaced apart from each other. The third connection ends 13c of the four reed pieces 13 are all arranged corresponding to the fourth side portion 211d of the anti-shake bracket 21 and are spaced apart from each other. Among them, the four reed pieces 13 surround at least part of the third through hole 311. The first reed piece 131 and the fourth reed piece 134 are located on the same side of the third through hole 311, and the second reed piece 132 and the third reed piece 133 are located on the opposite side of the third through hole 311.

[0261] Exemplarily, a limiting hole 135 may be provided at the first connection end 13a of the reed 13, and the second fixed end 12b of the suspension wire 12 may be embedded in the limiting hole 135 to achieve the fixed connection between the suspension wire 12 and the reed 13. Among them, the limiting hole 135 may be a gap formed by multiple bends of the first connection end 13a of the reed 13, or the limiting hole 135 may also be a through hole opened on the first connection end 13a of the reed 13. The present application does not make any limitation thereto. In other embodiments, the first connection end 13a of the reed 13 may not include the limiting hole 135, and the second fixed end 12b of the suspension wire 12 may be connected to the reed 13 by means of gluing, welding, etc. The first connection ends 13a of the four reeds 13 correspond to the four suspension wires 12 one by one. Exemplarily, the first connection end 13a of the first reed 131 may be connected to the second fixed end 12b of the first suspension wire 121, the first connection end 13a of the second reed 132 may be connected to the second fixed end 12b of the second suspension wire 122, the first connection end 13a of the third reed 133 may be connected to the second fixed end 12b of the third suspension wire 123, and the first connection end 13a of the fourth reed 134 may be connected to the second fixed end 12b of the fourth suspension wire 124.

[0262] Exemplarily, a plurality of fixing holes 136 may also be provided on the reed 13. The plurality of fixing holes 136 correspond to the plurality of fixing posts 212 one by one, and the fixing posts 212 may be embedded in the fixing holes 136 to achieve the fixed connection between the reed 13 and the anti-shake bracket 21.

[0263] 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 will undergo elastic deformation. The resultant force direction of the restoring forces generated by the four suspension wires 12 is along the opposite direction of the movement of the anti-shake bracket 21 relative to the base 11, so as to drive the anti-shake bracket 21 to move in the opposite direction relative to the base 11, enabling the anti-shake bracket 21 to move back to the equilibrium position. This can improve the linearity of the movement of the anti-shake bracket 21 and is also beneficial to maintaining the center of the anti-shake bracket 21 in the optical axis direction, improving the reliability and control accuracy of the motor 1. In the embodiments of the present application, the suspension wire 12 is connected to the anti-shake bracket 21 through the reed 13. In other embodiments, the second fixed end 12b of the suspension wire 12 may also be connected to the anti-shake bracket 21 through other structural members or directly. The present application does not make any limitation thereto.

[0264] In some embodiments, the reed 13 may also be made of a conductive material to take into account the signal transmission function.

[0265] Figure 33 Yes Figure 4 The structural schematic diagram of the motor 1 shown in another angle.

[0266] Such as Figure 33As shown, by way of example, the motor housing 14 may include a top plate 141 and a side frame 142, and 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 which are oppositely arranged.

[0267] In some embodiments, the motor housing 14 is assembled and cooperated with the base 11. The motor housing 14 covers the base 11, and the motor housing 14 cooperates with the base 11 to jointly encapsulate and protect the internal structure of the motor 1. Among them, the top plate 141 is provided with a fourth through hole 143, and the fourth through hole 143 penetrates the top plate 141 in the third direction Z, and part of the structure of the motor 1 is exposed through the fourth through hole 143. For example, part of the structure of the focusing bracket 31 is exposed.

[0268] Figure 34 is Figure 33 A partial exploded view of the motor 1 in some embodiments as shown. Figure 35 is Figure 34 A partial exploded view of the motor 1 in some embodiments as shown.

[0269] As Figure 34 and Figure 35 As shown in [relevant figures], in some embodiments, the motor 1 may further include a first buffer member 161. The first buffer member 161 may be fixed to the surface of the focusing bracket 31 facing away from the bottom plate 111, and the number of the first buffer members 161 may be two. The two first buffer members 161 are respectively arranged corresponding to the first raised area 1411 and the second raised area 1412. By providing the first buffer member 161, when the focusing bracket 31 moves upward in the third direction Z, the impact force between the focusing bracket 31 and the motor housing 14 is reduced, so as to avoid damage to the focusing bracket 31 due to hitting the top plate 141 during the movement. By way of example, the first buffer member 161 may be a flexible material such as liquid silicone or foam, and the first buffer member 161 may form an integral structure with the focusing bracket 31 through an injection molding process. In other embodiments, the first buffer member 161 may also be fixed to the focusing bracket 31 by bonding or other fixing means, and the present application does not limit this. By way of example, the sizes, shapes, etc. of the two first buffer members 161 may be the same or different, and the present application does not limit this. In other embodiments, the number of the first buffer members 161 may also be one, four, etc., and the present application does not limit this either.

[0270] In some embodiments, the motor 1 may further include a second buffer member 162. The second buffer member 162 may be fixed to the surface of the focusing bracket 31 facing the bottom plate 111, and the number of the second buffer members 162 may be four. The four second buffer members 162 may be fixed to the four corners of the focusing bracket 31. By providing the second buffer member 162, when the focusing bracket 31 moves downward along the third direction Z, the impact force between the focusing bracket 31 and the base 11 can be reduced, so as to avoid damage to the focusing bracket 31 due to hitting the base 11 during the movement. Exemplarily, the second buffer member 162 may be a flexible material such as liquid silicone or foam, and the second buffer member 162 may be integrally formed with the focusing bracket 31 through an injection molding process. In other embodiments, the second buffer member 162 may also be fixed to the focusing bracket 31 by bonding or other fixing means, and the present application does not limit this. Exemplarily, the sizes, shapes, etc. of the four second buffer members 162 may be the same or different, and the present application does not limit this. In other embodiments, the number of the second buffer members 162 may also be two, three, etc., and the present application does not limit this either.

[0271] In some embodiments, the motor 1 may further include a third buffer member 163. The third buffer member 163 may be fixed to one side of the anti-shake bracket 21 facing the side frame 142, and the number of the third buffer members 163 may be four. The four third buffer members 163 are respectively fixed to the four sides of the anti-shake bracket 21. By providing the third buffer member 163, when the anti-shake bracket 21 moves relative to the base 11 in the X-Y plane, the impact force between the anti-shake bracket 21 and the motor housing 14 can be reduced, so as to avoid damage to the anti-shake bracket 21 due to hitting the side frame 142 during the movement. Exemplarily, the third buffer member 163 may be a flexible material such as liquid silicone or foam, and the third buffer member 163 may be integrally formed with the anti-shake bracket 21 through an injection molding process. In other embodiments, the third buffer member 163 may also be fixed to the anti-shake bracket 21 by bonding or other fixing means, and the present application does not limit this. Exemplarily, the sizes, shapes, etc. of the four third buffer members 163 may be the same or different, and the present application does not limit this. In other embodiments, the number of the third buffer members 163 may also be two, three, etc., and the present application does not limit this either.

[0272] In some embodiments, the motor 1 may further include an anti-shake magnetic member 17, and the anti-shake magnetic member 17 is fixed to the second surface 111b of the base plate 111. Exemplarily, the anti-shake magnetic member 17 may include a first anti-shake magnetic member 171 and a second anti-shake magnetic member 172. The first anti-shake magnetic member 171 is located in the first border area 1111 and faces the first anti-shake magnetic member 222 to generate a magnetic attraction force with the first anti-shake magnetic member 222, so that the anti-shake bracket 21 is adsorbed on the base 11. The second anti-shake magnetic member 172 may be fixed to the second border area 1112 and faces the second anti-shake magnetic member 224 to generate a magnetic attraction force with the second anti-shake magnetic member 224, so that the anti-shake bracket 21 is adsorbed on the base 11. Exemplarily, the anti-shake magnetic member 17 may be made of a material capable of generating a magnetic attraction force with a magnet or other magnetic components, such as ferromagnetic materials, etc. The sizes, shapes, etc. of the first anti-shake magnetic member 171 and the second anti-shake magnetic member 172 may be the same or different, and the present application does not limit this. In other embodiments, the motor 1 may not include the first anti-shake magnetic member 171, or the motor 1 may not include the second anti-shake magnetic member 172.

[0273] In this embodiment, since the anti-shake bracket 21 has a tendency to approach the base 11 under the magnetic force, it can be ensured that the anti-shake bracket 21 remains in contact with the ball group 24, so as to achieve precise guidance during the movement of the anti-shake bracket 21 relative to the base 11, thereby improving the reliability and accuracy of optical anti-shake.

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

[0287] Among them, the second connection end 13b of the first reed 131 can be fixedly connected to the outgoing end 215b of the first trace 2151 by means of welding or conductive adhesive. The connection manner between the second connection end 13b of the second reed 132 and the outgoing end 215b of the second trace 2152, the connection manner between the second connection end 13b of the third reed 133 and the outgoing end 215b of the third trace 2153, and the connection manner between the second connection end 13b of the fourth reed 134 and the outgoing end 215b of the fourth trace 2154 can refer to the connection manner between the second connection end 13b of the first reed 131 and the outgoing end 215b of the first trace 2151, which will not be elaborated here.

[0288] Exemplarily, the third connection end 13c of the first reed 131 can also be electrically connected to the SDA signal of the drive chip of the variable aperture 6 (as Figure 2 shown).

[0289] ​ is ​ a schematic structural diagram of an embodiment of the circuit connecting the motor 1 shown to an external structure.

[0290] As ​As shown, exemplarily, the suspension wire 12 can be made of a conductive material, and the suspension wire 12 can serve as a transmission channel between the reed 13 and the module circuit board 3 (such as ​ shown). At this time, the first fixed ends 12a of the four suspension wires 12 (such as ​ shown) can be electrically connected to the four extension parts 1153 (such as ​ shown) 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 driving chip 332 or the variable aperture 6 (such as ​ shown) and the module circuit board 3.

[0292] In the foregoing embodiments, the anti-shake driving mechanism of the motor 1 mainly adopts a single-coil driving scheme. In some other embodiments, the motor 1 can also adopt a dual-coil driving scheme to provide a greater driving force, which is beneficial to improving the driving efficiency and increasing the optical anti-shake stroke. For example:

[0293] ​ is a partial structural schematic diagram of another motor 1 provided by an embodiment of the present application.

[0294] As ​ shown, in some embodiments, the first anti-shake coil 221 can include a first sub anti-shake coil 2211 and a second sub anti-shake coil 2212. The first sub anti-shake coil 2211 can be arranged facing the first anti-shake magnetic member 222, and the second sub anti-shake coil 2212 can be arranged facing the first anti-shake magnetic member 222. In other words, the first sub anti-shake coil 2211 and the second sub anti-shake coil 2212 can share the magnetic field generated by the first anti-shake magnetic member 222.

[0295] Exemplarily, the second anti-shake coil 223 can include a third sub anti-shake coil 2231 and a fourth sub anti-shake coil 2232. The third sub anti-shake coil 2231 can be arranged facing the second anti-shake magnetic member 224, and the fourth sub anti-shake coil 2232 can be arranged facing the second anti-shake magnetic member 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 member 224.

[0296] At this time, by adjusting the magnitude and direction of the current in the compensation coil 231 within the compensation mechanism 23, it can also be used to compensate for the torque generated at the center of the anti-shake bracket 21 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, 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.

[0297] In the foregoing embodiments, the suspension wire 12 is mainly used in the motor 1 to provide a restoring force. In some other embodiments, the elastic member 18 can also be used in the motor 1 for guiding. For example: This embodiment can include most of the technical solutions of the foregoing embodiments. The following mainly describes the differences between the two, and most of the same content between the two will not be elaborated.

[0298] ​ It is a partial structural schematic diagram of another motor 1 provided by an embodiment of the present application.

[0299] As ​ shown, in some embodiments, the base 11 can further include four fixing blocks 117. The four fixing blocks 117 are respectively fixed at the four corners of the bottom plate 111. The fixing block 117 can be provided with a receiving groove 1171. The receiving groove 1171 can be fixed to the bottom plate 111 and is located on the side of the fixing block 117 away from the first through hole 1115. The opening direction of the receiving groove 1171 can be on the same side of the bottom plate 111 as the first surface 111a. The motor 1 can further include an elastic member 18. The elastic member 18 can be fixedly connected to the fixing block 117. Exemplarily, the number of the elastic members 18 can be four. The four elastic members 18 can be fixedly connected to the four fixing blocks 117 one by one. The shapes and sizes of the four elastic members 18 can be the same, and the four elastic members 18 can adopt the same reference numerals. It can be understood that the present application does not limit the number of the elastic members 18.

[0300] Exemplarily, the elastic member 18 can include the first end 181 of the elastic member 18, the middle part 182 of the elastic member 18, and the second end 183 of the elastic member 18. The middle part 182 of the elastic member 18 can be bent and connected between the first end 181 and the second end 183 of the elastic member 18. The first end 181 of the elastic member 18 can be bent and connected relative to the middle part 182 of the elastic member 18. The first end 181 of the elastic member 18 can be fixedly connected to the corresponding fixing block 117. The middle part 182 of the elastic member 18 can be installed in the receiving groove 1171. The fixing block 117 can play a role in fixing and supporting the elastic member 18, realizing the fixed connection between the elastic member 18 and the base 11.

[0301] Exemplarily, a positioning hole 1831 may be provided on the second end 183 of the elastic member 18, and a positioning post 1832 may be correspondingly provided on the anti-shake bracket 21. The positioning post 1832 may be embedded in the positioning hole 1831 to realize the 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 will undergo elastic deformation. The resultant force direction of the restoring forces generated by the four elastic members 18 is along the opposite direction of the movement of the anti-shake bracket 21 relative to the base 11, so as to drive the anti-shake bracket 21 to move in the reverse direction relative to the base 11, enabling the anti-shake bracket 21 to move back to the equilibrium position, which can improve the linearity of the movement of the anti-shake bracket 21 and is also beneficial to maintaining the center of the anti-shake bracket 21 in the optical axis direction, improving the reliability and control accuracy of the motor 1.

[0302] Exemplarily, 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.

Any arbitrary combination of the features in different embodiments is also within the protection scope of the present application. That is to say, the above-described multiple embodiments may also be arbitrarily combined according to actual needs.
