Description

Technical Field

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

[0002] At present, camera modules usually use VCM (Voice Coil Motor) motors to detect and feedback the mobile phone shake within a certain frequency and amplitude range in real time when taking pictures, and perform reverse compensation to achieve focus and image stabilization functions, further improve camera functions and quality, and ensure image quality. However, traditional motors usually need to set up two different drive mechanisms to drive the mover to move along the optical axis to achieve autofocus, and drive the mover to move along a plane perpendicular to the optical axis to achieve optical image stabilization. In this way, the size of the motor is often large, which is not conducive to the miniaturization of the motor. Summary of the invention

[0003] The embodiments of the present application provide a motor, a camera module including the motor, and an electronic device including the camera module, aiming to obtain a motor with a simpler and more compact overall structure that can be miniaturized and thinned.

[0004] In a first aspect, the present application provides a motor. The motor includes a base, an anti-shake bracket, a focus bracket, a first magnetic component, a first focus coil, and a first anti-shake coil. The anti-shake bracket is movably connected to the base; the focus bracket is located on the inner side of the anti-shake bracket and is movably connected to the anti-shake bracket, and the focus bracket is used to install a lens; the first magnetic component is fixed to the anti-shake bracket; the first focus coil is fixed to the focus bracket, and the first focus coil is arranged facing the first magnetic component to drive the focus bracket to move in a first direction relative to the base; the first anti-shake coil is fixed to the base, and the first anti-shake coil is arranged facing the first magnetic component to drive the anti-shake bracket to drive the focus bracket to move in a second direction relative to the base, and the second direction intersects with the first direction; the first anti-shake coil, the first magnetic component, and the first focus coil are arranged in sequence in the second direction.

[0005] The motor in the embodiment of the present application includes a focus bracket, an anti-shake bracket, a first focus coil, a first anti-shake coil and a first magnetic member. The first magnetic member can cooperate with the first focus coil to drive the focus bracket to move relative to the base in a first direction; the first magnetic member can also cooperate with the first anti-shake coil to drive the anti-shake bracket to drive the focus bracket to move relative to the base in a second direction. When the lens is mounted on the focus bracket, it can be considered that the first direction is parallel to the optical axis direction of the lens. In other embodiments, the first direction can also intersect with the optical axis direction of the lens, and the present application does not limit this. By controlling the focus bracket to move in the first direction relative to the base, the lens can be driven to move in the first direction (that is, the optical axis direction) relative to the base to achieve the focusing function of the motor; by controlling the focus bracket to move in the second direction relative to the base, the lens can be driven to move in the second direction relative to the base, that is, the lens can move relative to the base in a plane perpendicular to the optical axis to achieve the anti-shake function of the motor.

[0006] In other words, the motor in the present embodiment is an integrated motor with both anti-shake and focus functions, and the focus bracket is located on the inner side of the anti-shake bracket. Compared with a split motor in which the anti-shake bracket and the focus bracket are separately arranged, the motor in the present embodiment is smaller in size and more compact in structure, which is conducive to reducing the size of the motor. At the same time, the first magnetic component in the motor in the present embodiment can cooperate with the first focus coil to control the movement of the focus bracket, and can also cooperate with the first anti-shake coil to control the anti-shake bracket to drive the focus bracket to move. Compared with the need to set up multiple groups of different magnetic components to cooperate with the focus coil to control the movement of the focus bracket in the first direction, and cooperate with the anti-shake coil to drive the anti-shake bracket to move in the second direction, the overall structure of the motor in the present embodiment is simpler and more compact, which is conducive to realizing the miniaturization of the motor.

[0007] In the present embodiment, the first anti-shake coil, the first magnetic component and the first focusing coil in the motor are arranged in sequence in the second direction, which can also save the space of the motor in the first direction (that is, the height direction of the motor), and can also make full use of the space in the height direction of the motor, which is beneficial to improve the utilization rate of the internal space of the motor, making the structure of the motor more compact, and is also beneficial to realize the thinning and miniaturization of the motor.

[0008] In addition, the first magnetic component is located between the first anti-shake coil and the first focus coil, which can improve the reliability of the motor while ensuring the focusing performance and anti-shake performance of the motor. Specifically, when the first magnetic component is located between the first anti-shake coil and the first focus coil, the first magnetic component can isolate the first anti-shake coil from the first focus coil, and prevent the magnetic fields generated by the first anti-shake coil and the second focus coil from overlapping and interfering with each other after being energized, forming a crosstalk phenomenon, affecting the control accuracy of the focusing process and the anti-shake process, and thus affecting the reliability of the motor.

[0009] In a possible implementation, the winding planes of the first anti-shake coil and the first focus coil are parallel to the first direction. In other words, the first anti-shake coil and the first focus coil are vertically arranged, which is conducive to reducing the size of the motor in the second direction and realizing the miniaturization of the motor.

[0010] In a possible implementation, the driving force for the focus bracket to move in the first direction is the Ampere force formed on the first focus coil when the energized first focus coil is in the magnetic field of the first magnetic part; the driving force for the anti-shake bracket to move in the second direction is the attraction or repulsion between the electromagnet formed by the first anti-shake coil after being energized and the first magnetic part. At this time, the principle of driving the focus bracket to move is different from the principle of driving the anti-shake bracket to move, so as to ensure that the first magnetic part can be reused while the first anti-shake coil, the first magnetic part and the first focus coil are arranged in the second direction, and the first magnetic part can cooperate with the first focus coil to realize the focusing function, and can also cooperate with the first anti-shake coil to realize the anti-shake function.

[0011] In a possible implementation, the first magnetic member includes a first magnet and a second magnet, the first magnet and the second magnet are arranged in a first direction, the polarity direction of the first magnet is opposite to the polarity direction of the second magnet, and is parallel to the second direction; the first anti-shake coil includes a first sub-anti-shake coil and a second sub-anti-shake coil, the first sub-anti-shake coil faces the first magnet, and the second sub-anti-shake coil faces the second magnet. In this embodiment, the first sub-anti-shake coil faces the first magnet, and it can be considered that the first anti-shake magnetic member and the first anti-shake magnetic member can maintain a positive relationship or a nearly positive relationship, and the projection of the first sub-anti-shake coil along the second direction is only located or almost only located in the first magnet. At this time, the resultant force of the Ampere force formed on the first sub-anti-shake coil after power-on is zero, the magnetic flux passing through the first sub-anti-shake coil is the largest, the first sub-anti-shake coil will form a first electromagnet, and similarly, the second sub-anti-shake coil after power-on will also form a second electromagnet.

[0012] By setting the first sub-anti-shake coil and the second sub-anti-shake coil to correspond to the first magnet and the second magnet respectively, the driving force in the motor that pushes the anti-shake bracket to move in this embodiment may include the magnetic force between the first electromagnet and the first magnet and the magnetic force between the second electromagnet and the second magnet. The magnetic force may be an attractive force or a repulsive force, which is beneficial to increase the size of the driving force, improve the driving efficiency, and increase the optical anti-shake stroke. In other embodiments, the first magnetic member may also include a first sub-magnetic member and a second sub-magnetic member arranged in a first direction, and the polarity directions of the first sub-magnetic member and the second sub-magnetic member are arranged in the same manner, and both have two opposite polarity directions; or, the first magnetic member is a Halbach magnet array.

[0013] In a possible implementation, the winding planes of the first sub-anti-shake coil and the second sub-anti-shake coil are parallel to the first direction. By setting the winding planes of the first sub-anti-shake coil and the second sub-anti-shake coil to be parallel to the first direction, in other words, the first sub-anti-shake coil and the second sub-anti-shake coil are arranged vertically, which is conducive to reducing the size of the motor in the second direction and realizing the miniaturization of the motor.

[0014] In one possible implementation, the first focusing coil includes a first side and a second side that are arranged relative to each other along a first direction, the first side of the first focusing coil is arranged relative to the first magnet, and the second side of the first focusing coil is arranged relative to the second magnet. When current is passed through the first focusing coil, the current flow direction of the first side of the first focusing coil is opposite to the current flow direction of the second side of the first focusing coil, and the polarity directions of the first magnet and the second magnet are opposite. Therefore, the Ampere force exerted on the first side of the first focusing coil in the magnetic field generated by the first magnet is in the same direction as the Ampere force exerted on the second side of the first focusing coil in the magnetic field generated by the second magnet, and the combined force formed by the superposition can provide a greater driving force for the focusing process of the motor, which is beneficial to improving the driving efficiency and increasing the optical focusing stroke.

[0015] In one possible implementation, the base includes a bottom plate and a first side plate, the first side plate is connected to the surface of the bottom plate, the anti-shake bracket is located on the inner side of the first side plate and is movably connected to the bottom plate; the anti-shake bracket includes a first edge portion, the first edge portion is arranged opposite to the first side plate, the first magnetic component is fixed to the first edge portion, and the first anti-shake coil is fixed to the first side plate. At this time, the first edge portion can provide strength support for the first magnetic component, and the first side plate can also provide strength support for the first anti-shake coil, so that the relative position of the first magnetic component and the first anti-shake coil is more stable. In other embodiments, the first side plate may not be provided in the base, and the first anti-shake coil may be fixed to the bottom plate by a circuit board or other structure.

[0016] In a possible implementation, the first side portion is provided with a first through hole, the first through hole connects the inner side and the outer side of the anti-shake bracket; the first magnetic member is at least partially located in the first through hole. In this case, the first magnetic member and the anti-shake bracket are compactly arranged, which is conducive to improving space utilization.

[0017] In a possible implementation, the base includes a second side plate, the second side plate is connected to the surface of the bottom plate, the second side plate is located on a side of the anti-shake bracket away from the first side plate, the anti-shake bracket includes a second edge portion, the second edge portion is arranged opposite to the second side plate; the motor includes a second magnetic part and a second anti-shake coil; the second magnetic part is fixed to the second edge portion, the second anti-shake coil is fixed to the second side plate, and the second anti-shake coil is arranged facing the second magnetic part to drive the anti-shake bracket to drive the focus bracket to move relative to the base along the second direction. By arranging the second anti-shake coil to cooperate with the second magnetic part, the driving force in the motor along the second direction can be increased, so that the motor can drive the lens to achieve a larger angle of anti-shake process.

[0018] In a possible implementation, the motor further includes a second focus coil, which is fixed to a side of the focus bracket facing away from the first focus coil; the second focus coil is arranged facing the second magnetic member to drive the focus bracket to move along the first direction relative to the base. By arranging the second focus coil to cooperate with the second magnetic member, the driving force in the motor along the first direction can be increased, which is conducive to the focus bracket carrying a lens with a larger mass and driving it to achieve the focusing process.

[0019] In a possible implementation, the motor further includes a third magnetic component and a third anti-shake coil, the third magnetic component is mounted on the anti-shake bracket, the third anti-shake coil is arranged facing the third magnetic component, and the third magnetic component is used to drive the anti-shake bracket to move along a third direction relative to the base, and the third direction intersects with both the first direction and the second direction; the third anti-shake coil and the third magnetic component are arranged in the first direction. At this time, the cooperation of the third magnetic component and the third anti-shake coil can provide the lens with a degree of freedom to move along the third direction, which is conducive to increasing the application range of the motor and optimizing the anti-shake performance.

[0020] In addition, by arranging the third anti-shake coil and the third magnetic component in the first direction, during the movement of the anti-shake bracket relative to the base, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the third magnetic component and the third anti-shake coil. The above magnetic gap is not affected by the movement of the anti-shake bracket. Therefore, the problem of rapid decrease in driving force due to 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 conducive to the anti-shake design with a large stroke.

[0021] In a possible implementation, the winding direction of the third anti-shake coil is parallel to the third direction. In this case, the third anti-shake coil can be arranged horizontally, which is conducive to reducing the size of the motor in the first direction and realizing miniaturization of the motor.

[0022] In a possible implementation, the base includes a bottom plate, a first fixing block, a second fixing block, and a fixing plate, the first fixing block and the second fixing block are fixed to the bottom plate at intervals, one end of the fixing plate is fixed to the first fixing block, and the other end is fixed to the second fixing block, the bottom plate, the first fixing block, the second fixing block, and the fixing plate surround an accommodating space; the third anti-shake coil is fixed to a side of the fixing plate facing the accommodating space, and at least part of the third magnetic member extends into the accommodating space. At this time, the third anti-shake coil, the third magnetic member, and the base are arranged compactly, which is conducive to improving space utilization.

[0023] In a possible implementation, the motor further includes a ball group, the ball group is mounted on the base, and the anti-shake bracket is movably connected to the base through the ball group. Each ball group may include multiple balls, and the number of balls may be five, sixteen or thirty-two, etc., which is not limited in the present application. In this embodiment, the anti-shake bracket and the focus bracket are movably connected through the ball group, which can reduce the friction resistance between the ball and the anti-shake bracket while ensuring sufficient support force, and can reduce the demand for the driving force during the movement of the anti-shake bracket, that is, it is conducive to reducing the size of the first magnetic member and / or the first anti-shake coil, which is conducive to miniaturization of the motor, and the diameter of each ball in the ball group is smaller than that of a single ball, which is also conducive to shortening the interval between the anti-shake bracket and the base, and is conducive to thinning the motor. In addition, the ball group can provide multi-point support for the anti-shake bracket, which is conducive to dispersing stress, preventing the deformation of the ball due to excessive concentration of force in a single direction when it is hit, and can improve the reliability of the ball group supporting the anti-shake bracket and structural parts such as the lens.

[0024] In a possible implementation, the ball group includes a first ball group, a second ball group and a third ball group, and the first ball group, the second ball group and the third ball group are arranged in a triangle. 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, and make the movement of the anti-shake bracket safer and more reliable. In this embodiment, the position of the ball group is arranged according to the principle of triangle stability, which can reduce the number of ball groups in the motor while ensuring the reliability of the ball group, which is conducive 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 also include a fourth ball group, which is not limited in this application.

[0025] In a possible implementation, the centers of the first ball group, the second ball group, and the third ball group are located in the optical axis direction of the lens. In this embodiment, the center of the anti-shake bracket can also be located on the optical axis of the lens. In other words, the centers of the first ball group, the second ball group, and the third ball group can be colinear with the center of the anti-shake bracket. In this case, unnecessary losses and influences caused by the centers of the first ball group, the second ball group, and the third ball group deviating from the center of the anti-shake bracket can be avoided.

[0026] In a possible implementation, the diameter of the balls of the ball group is less than or equal to 0.3 mm. In this case, the motor in this embodiment can reduce the distance between the ball group and the anti-shake bracket while ensuring the supporting function of the balls, which is conducive to realizing the thinning and miniaturization of the motor.

[0027] In one possible implementation, the friction coefficient between the ball group and the base is less than or equal to 0.06, which is beneficial to minimize the friction resistance and friction heat that may be generated during the sliding process of the ball within the effective limited stroke, and is beneficial to improving the wear resistance of the ball and extending its service life.

[0028] It is understandable that the friction coefficient between the balls of the ball group and the base can be less than or equal to 0.06 by reasonably configuring the relative positions of the first ball group, the second ball group and the third ball group, as well as design parameters such as the number and diameter of the balls in each ball group.

[0029] In a possible implementation, the motor further includes a metal part, which is fixed on the base; the anti-shake bracket is movably connected to the metal part through at least two ball groups. The metal part can be a steel sheet, etc., which is not limited in this application. By providing a metal part and movably connecting the ball group to the metal part, the friction force on the ball group during movement can be reduced, and the smoothness of the ball rotation process can be improved, which is conducive to improving the response rate of the anti-shake bracket when it is movably connected to the metal part through the ball group.

[0030] In one possible implementation, the metal part is embedded in the base, the base is provided with a groove, the metal part is exposed relative to the base through the groove, and the ball group is located in the groove. By arranging the metal part to be embedded in the base, the metal part can provide a certain hardness support to the base, enhance the strength of the base, and avoid deformation of the base. In addition, the ball group is arranged in the groove and contacts the metal part, which can reduce the friction resistance of the ball group while improving the compactness of the arrangement between the ball group and the base, which is conducive to the miniaturization of the motor.

[0031] In a possible implementation, the motor further includes a sliding shaft, which is fixed to the anti-shake bracket, and the focus bracket is slidably connected to the anti-shake bracket through the sliding shaft, and the sliding shaft is made of magnetic conductive material; the motor further includes a focus magnetic suction piece, which is fixed to the focus bracket, and the focus magnetic suction piece is arranged close to the sliding shaft to generate a magnetic attraction force with the sliding shaft, and the magnetic attraction force causes the focus bracket to be adsorbed on the sliding shaft. The sliding shaft can guide the movement process of the focus bracket. By utilizing the magnetic attraction force between the focus magnetic suction piece and the sliding shaft, the focus bracket can be tightly fitted with the sliding shaft, and the focus bracket can move along the extension direction of the sliding shaft, which can avoid the focus bracket from being displaced in other directions during the focusing process, and can improve the reliability of the focusing process. In addition, the driving force when the focus bracket moves only needs to overcome its own gravity, the lens gravity, and the friction between the sliding shaft, and has no obvious correlation with the movement stroke, so that the focus bracket can achieve a large stroke movement in the first direction.

[0032] In some possible implementations, the motor further includes an anti-shake magnetic component, which is fixed to the base and disposed facing the first magnetic component and the second magnetic component, so as to generate a magnetic attraction with the first magnetic component and the second magnetic component, so that the anti-shake bracket is adsorbed on the base. The anti-shake magnetic component generates a magnetic attraction with the first magnetic component and the second magnetic component, so that the anti-shake bracket has a tendency to approach the base, ensuring that the base, the ball group, and the anti-shake bracket are in contact during the movement of the anti-shake bracket, and preventing the anti-shake bracket from moving along the first direction during the movement, which affects the reliability and control accuracy of the motor.

[0033] In a possible implementation, the base includes a bottom plate and four fixed blocks, and the four fixed blocks are respectively fixed at the four corners of the bottom plate; the motor also includes four elastic members, the first ends of the four elastic members are fixedly connected to the four fixed blocks one by one, and the second ends of the four elastic members are fixedly connected to the four positions of the anti-shake bracket one by one. In other words, it can also be considered that the elastic members are fixedly connected to the four corners of the anti-shake bracket correspondingly. By setting the elastic members, an elastic connection between the base and the anti-shake bracket can be achieved. When the anti-shake bracket moves along the second direction relative to the base, the four elastic members will undergo elastic deformation. The combined force direction of the restoring force generated by the four elastic members is in the opposite direction of the movement direction of the anti-shake bracket, so as to drive the anti-shake bracket to move in the opposite direction relative to the base, so that the anti-shake bracket moves back to the equilibrium position, which can improve the linearity of the movement of the anti-shake bracket, and can also help to maintain the center of the anti-shake bracket in the direction of the optical axis, thereby improving the reliability and control accuracy of the motor.

[0034] In a possible implementation, the fixing block is provided with a receiving groove, and the middle part of the elastic member is located in the receiving groove; the motor further includes a damping rubber, which is located in the receiving groove and wraps the middle part of part of the elastic member. When the anti-shake bracket moves relative to the base, since the middle part of the elastic member is located in the receiving groove and the receiving groove is filled with the damping rubber, the damping rubber can play a role in oscillation suppression and can play a better role in shock absorption and buffering.

[0035] In a possible implementation, the fixed block includes a side surface and a top surface and a bottom surface that are disposed opposite to each other, and the side surface is connected between the top surface and the bottom surface; the motor includes a conductive member, and a portion of the conductive member is embedded in the fixed block; the elastic member is a conductive material, and the first end of the elastic member is bent and connected relative to the middle part of the elastic member, and the middle part of the elastic member is opposite to and spaced from the side surface of the fixed block, and the first end of the elastic member is fixed to the conductive member. It can be understood that the conductive member can usually be a wire or a flexible circuit board, etc. At this time, the first end of the elastic member can contact the top surface of the fixed block, so that the fixed block can provide a certain support force for the elastic member, and the first end of the elastic member can be electrically connected to the conductive member, thereby avoiding the bending setting of the conductive member and improving the stability of the electrical connection in the motor.

[0036] In a possible implementation, the motor also includes a reed, which is made of a conductive material. One end of the conductive member is used to electrically connect to the module circuit board, and the other end of the conductive member is electrically connected to the first end of the elastic member, and the first end of the elastic member is also electrically connected to the reed. At this time, the elastic member can serve as a transmission channel between the reed and the conductive member. Exemplarily, the reed includes a first conductive spring, a second conductive spring, a third conductive spring and a fourth conductive spring, and the conductive member includes a first conductive member, a second conductive member, a third conductive member and a fourth conductive member. The four elastic members serve as a transmission channel between the first conductive member and the third conductive spring, a transmission channel between the second conductive member and the fourth conductive spring, a transmission channel between the third conductive member and the second conductive spring, and a transmission channel between the fourth conductive member and the first conductive spring.

[0037] In a second aspect, the embodiment of the present application further provides a camera module, including a lens, an image sensor, and a motor of any one of the above, wherein the lens is installed in the motor, and the image sensor is located on the light-emitting side of the lens. The motor of the camera module in this embodiment is relatively small in size, has a simple and compact overall structure, and can achieve long-stroke anti-shake, which can save space in the camera module while enabling the camera module to have a higher imaging quality.

[0038] In some possible implementations, the camera module further includes a variable aperture, which is located on the light-incoming 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 incoming light, so that the camera module can maintain a constant shooting quality under various brightness conditions.

[0039] In a possible implementation, the camera module further includes a module circuit board, the motor is fixed to the module circuit board, the motor and the image sensor are located on the same side of the module circuit board, and the motor and the variable aperture are both electrically connected to the module circuit board.

[0040] In a third aspect, the embodiment of the present application further provides an electronic device, comprising a device housing and any of the above-mentioned camera modules, the camera module being arranged in the device housing. The camera module has the characteristics of miniaturization and good shooting quality, which is conducive to saving the internal space of the electronic device while ensuring the shooting performance of the electronic device, thereby realizing the miniaturization of the electronic device.

The orientation terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only reference to the directions of the drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0076] It is to be understood that the specific implementations described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0077] Figure 1a It is a structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0078] like Figure 1a As 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., which have a camera function. Figure 1a The electronic device 1000 of the illustrated embodiment is introduced by taking a mobile phone as an example.

[0079] Figure 1b yes Figure 1a The illustrated electronic device 1000 is a partial cross-sectional schematic diagram taken along AA in some embodiments.

[0080] like Figure 1a and Figure 1b As shown, in some embodiments, the electronic device 1000 may include a camera module 100, a device housing 200 and a screen 300. The camera module 100 may be a rear camera module or a front camera module. It should be noted that Figure 1a The following figures and the related drawings only schematically illustrate some components of the electronic device 1000, and the actual shapes, sizes, positions and structures of these components are not limited to the following. Figure 1a In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300 .

[0081] The device housing 200 may include a frame 201 and a back cover 202, and the back cover 202 is fixed to the frame 201. Exemplarily, the back cover 202 may be fixedly connected to the frame 201 by means of gluing, snapping, etc. The back cover 202 may also be an integrally formed structure with the frame 201, that is, the back cover 202 and the frame 201 are an integral structure.

[0082] In some embodiments, the screen 300 may be located on a side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 may be located on both sides of the frame 201, respectively. The screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 may be used to place components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 may be a flat screen or a curved screen.

[0083] For example, 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 back cover 202. The back cover 202 may be provided with a light-transmitting hole 203. The shape of the light-transmitting hole 203 is not limited to the following. Figure 1a The light-transmitting hole 203 connects the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting hole 203. The camera module 100 can collect the light entering the inside of the electronic device 1000.

[0084] Figure 2 yes Figure 1a A partially exploded schematic diagram of some embodiments of the camera module 100 is shown.

[0085] like Figure 2 As shown, the camera module 100 includes a motor 1, a lens 2, a module circuit board 3, an image sensor 4, electronic components 5, a filter holder 6a, a filter 6b and a variable aperture 7. The image sensor 4 is also called a photosensitive chip or a photosensitive element. The image sensor 4 is used to collect ambient light and convert the image information carried by the ambient light into an electrical signal. The electronic component 5 can be a capacitor, an inductor, a resistor or a chip. Figure 2 The electronic components 5 are schematically framed by a dotted frame.

[0086] It is understandable 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 electronic component 5, and / or the filter holder 6a, and / or the filter 6b, and / or the variable aperture 7.

[0087] It is understandable that, for the convenience of description, the camera module 100 is defined as having a first direction Z, a second direction X, and a third direction Y. The third 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 third direction Y, the first direction Z may be the height direction of the camera module 100, and the first direction Z is perpendicular to the third direction Y and the second direction X. In other embodiments, the coordinate system setting of the camera module 100 may be flexibly set according to specific actual needs.

[0088] like Figure 1b and Figure 2 As shown, the image sensor 4 can be arranged on the module circuit board 3 and electrically connected to the module circuit board 3. At this time, the image sensor 4 and the module circuit board 3 can transmit signals to each other. In addition, the electronic component 5 is also fixed to the module circuit board 3 and electrically connected to the module circuit board 3. At this time, the electronic component 5 and the module circuit board 3 can transmit signals to each other.

[0089] Exemplarily, the filter holder 6a is fixedly connected to the module circuit board 3. The filter holder 6a and the image sensor 4 are located on the same side of the module circuit board 3. The filter holder 6a is provided with a light through hole 6c. The filter 6b is fixedly connected to the filter holder 6a. The filter 6b can be located in the light through hole 6c. The filter 6b is also arranged opposite to the image sensor 4. The filter 6b can be used to filter infrared light or blue light in the light before entering the image sensor 4, so as to ensure that the image sensor 4 has better imaging quality.

[0090] like Figure 1b As shown, the motor 1 is fixed to the module circuit board 3. The motor 1 and the image sensor 4 are located on the same side of the module circuit board 3. The lens 2 is mounted on the motor 1. The image sensor 4 is located on the light-emitting side of the lens 2. It can be understood that in the first direction Z, the image sensor 4, the filter 6b 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 6b is located between the lens 2 and the image sensor 4.

[0091] It is understandable that the lens 2 can be used to collect ambient light. The optical axis direction of the lens 2 can be parallel to the first direction Z of the camera module 100. The optical axis direction of the lens 2 is the same as the optical axis direction of the camera module 100.

[0092] It can be understood that compared with the solution of fixing the motor on the filter holder, this embodiment can avoid the stacking of the motor 1 and the filter holder 6a in the first direction Z by fixing the motor 1 on the module circuit board 3, that is, the motor 1 and the filter holder 6a can be staggered in the XY plane, thereby greatly reducing the height of the camera module 100.

[0093] It is understandable that the motor 1 can be a focus motor. In this way, the motor 1 can achieve auto focus (AF) by controlling the movement of the lens 2 along the first direction Z. The motor 1 can also be an anti-shake motor. In this way, the motor 1 can control the movement of the lens 2 along a plane perpendicular to the first direction Z (ie, the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 shakes in the XY plane due to external force, the movement of the lens 2 in the XY plane can be controlled by the motor 1 to offset the shaking stroke of the lens 2 in the XY plane to avoid or reduce the position bias of the lens 2 caused by shaking. In other words, the camera module 100 of the present application can control the movement of the lens 2 in the XY plane by the motor 1 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100. The motor 1 can also be an anti-shake and focus integrated motor 1. In this way, the motor 1 can achieve auto focus by controlling the lens 2, and can also achieve optical image stabilization by controlling the lens 2. This embodiment is described by taking the motor 1 as an example in which the motor 1 is an anti-shake and focus integrated motor 1 .

[0094] like Figure 2 As shown, exemplarily, the camera module 100 includes a variable aperture 7. The variable aperture 7 can be located on the light incident side of the lens 2. The variable aperture 7 has an aperture hole 7a, and the size of the aperture hole 7a can be automatically adjusted. Light can enter the lens 2 through the aperture hole 7a of the variable aperture 7. The variable aperture 7 is used to adjust the amount of light entering, so that the camera module 100 can maintain a constant shooting quality under various brightness conditions.

[0095] The above text generally introduces the structure of the camera module 100 in combination with the relevant drawings, and the following text will specifically introduce the structure of the motor 1 in combination with the relevant drawings.

[0096] Figure 3 yes Figure 2 A partially exploded schematic diagram of some embodiments of the motor 1 is shown.

[0097] like Figure 3 As shown, the motor 1 may include a base 10 , a driving mechanism 20 , an anti-shake bracket 30 , a focus bracket 40 , a pressure plate 50 , a housing 51 and a sliding shaft 52 .

[0098] Exemplarily, the driving mechanism 20 may include a first anti-shake coil 21 , a second anti-shake coil 22 , a third anti-shake coil 23 , a first magnetic member 24 , a second magnetic member 25 , a third magnetic member 26 , a first focusing coil 27 and a second focusing coil 28 .

[0099] For example, the number of the sliding shafts 52 may be two, or other numbers. For example, the sliding shaft 52 may include a first sliding shaft 521 and a second sliding shaft 522 .

[0100] Figure 4 yes Figure 3 A partial structural schematic diagram of the base 10 is shown.

[0101] like Figure 4 As shown, the base 10 may include a bottom plate 11, which may be roughly square, and the bottom plate 11 may include a first side area 111a, a second corner area 112b, a second side area 112a, a third corner area 113b, a third side area 113a, a fourth corner area 114b, a fourth side area 114a and a first corner area 111b connected end to end in sequence, wherein the first side area 111a and the second side area 112a are arranged at an angle, the third side area 113a and the first side area 111a are arranged opposite to each other, and the fourth side area 114a and the second side area 112a are arranged opposite to each other. Exemplarily, the first side area 111a and the second side area 112a may be arranged perpendicular to each other, the third side area 113a may be parallel to the first side area 111a, and the fourth side area 114a may be parallel to the second side area 112a.

[0102] For example, the bottom plate 11 may be provided with a first through hole 110, and the bottom plate 11 has a first surface 115 and a second surface ( Figure 4 The first through hole 110 may penetrate the first surface 115 and the second surface, and the first through hole 110 is located between the first side area 111a and the third side area 113a, and between the second side area 112a and the fourth side area 114a. That is, the first side area 111a, the second side area 112a, the third side area 113a and the fourth side area 114a are arranged around the first through hole 110.

The first groove 1161, the second groove 1162, and the third groove 1163 may be used to install the structural parts in the motor 1. By providing a plurality of grooves 116 on the bottom plate 11 to install the structural parts, the structural parts are at least partially embedded in the bottom plate 11, so that the space occupied by the motor 1 in the first direction Z can be reduced, and the compact arrangement between the structural parts can also improve the space utilization rate in the motor 1.

[0104] Exemplarily, the size of the opening of the first groove 1161 is consistent with the size of the opening of the second groove 1162, and the size of the opening of the third groove 1163 is larger than the size of the opening of the first groove 1161. The opening of the first groove 1161, the opening of the second groove 1162, and the opening of the third groove 1163 can all be roughly elliptical. In other embodiments, the size, shape, extension direction, and other related designs of the openings of the first groove 1161, the second groove 1162, and the third groove 1163 can be adjusted as needed, and this application is not limited to this.

In other embodiments, the metal part 184 may also be fixed to the surface of the bottom plate 11, and part of the metal part 184 is located in the groove 116, which is not limited in the present application.

This is not limited in the present application. In other embodiments, the motor 1 may not include the second ball group 182; or, the ball group 18 may also include a fourth ball group, etc.

[0115] The first ball group 181 may be disposed in the first groove 1161. The balls of the first ball group 181 may roll in the first groove 1161. Part of the balls of the first ball group 181 may be located in the first groove 1161, and part of the balls may be located outside the first groove 1161.

[0116] In addition, the second ball group 182 may be disposed in the second groove 1162. The balls of the second ball group 182 may roll in the second groove 1162. Part of the balls of the second ball group 182 may be located in the second groove 1162, and part of the balls may be located outside the second groove 1162.

[0117] In addition, the third ball group 183 may be disposed in the third groove 1163. The balls of the third ball group 183 may roll in the third groove 1163.

[0119] Figure 7 yes Figure 6 An enlarged schematic diagram of the structure at position M in the motor 1 is shown.

[0120] like Figure 6 and Figure 7As shown, in some embodiments, the motor 1 further includes an elastic member 55, and the elastic member 55 can be fixedly connected to the fixed block 14. Exemplarily, the number of the elastic members 55 can be four, and the four elastic members 55 can be fixedly connected to the four fixed blocks 14 in a one-to-one correspondence. The shapes and sizes of the four elastic members 55 can be the same, and the four elastic members 55 can use the same reference numeral. It can be understood that the present application does not limit the number of the elastic members 55.

[0121] Exemplarily, the elastic member 55 may include a first end 551 of the elastic member 55, a middle portion 553 of the elastic member 55 and a second end 552 of the elastic member 55, and the middle portion 553 of the elastic member 55 may be bent and connected between the first end 551 of the elastic member 55 and the second end 552 of the elastic member 55.

[0122] Exemplarily, the first end 551 of the elastic member 55 can be bent and connected relative to the middle portion 553 of the elastic member 55, the middle portion 553 of the elastic member 55 is opposite to and spaced apart from the outer side surface 1413 of the fixed block 14, and the first end 551 of the elastic member 55 can be fixedly connected to the corresponding fixed block 14 to achieve the fixing and supporting effect of the base 10 on the elastic member 55.

[0123] Exemplarily, the middle portion 553 of the elastic member 55 may be located in the receiving groove 15, and the receiving groove 15 may be filled with a damping material. The damping material may wrap at least a portion of the middle portion 553 of the elastic member 55. The damping material may be a material having a certain elastic deformation capacity, which can suppress vibrations and also can provide shock absorption and buffering. Exemplarily, the damping material may be a damping glue such as rubber. When the elastic member 55 is deformed by an external force, the damping glue will deform accordingly, and a large internal friction will be generated in the damping glue to absorb and consume the vibration energy caused by the torque, so that the deformation of the elastic member 55 is hindered and the vibration is attenuated. The damping characteristics of the damping glue are stable and the response speed is fast, so that the elastic member 55 can quickly return to a stable posture after being subjected to force, which is also beneficial to improving the reliability of the motor 1.

[0124] Exemplarily, the second end 552 of the elastic member 55 may be disposed coplanarly with the middle portion 553 of the elastic member 55 , and a mounting hole 554 may be provided on the second end 552 of the elastic member 55 .

[0128] Exemplarily, the motor 1 may further include a first position sensor 531 , which may be fixed to a side of the first side plate 12 facing the first through hole 110 , and is used to implement position detection.

[0136] like Figure 8 As shown, the anti-shake bracket 30 may include a first side portion 31a, a second corner portion 32b, a third side portion 33a, a third corner portion 33b, a second side portion 32a, a fourth corner portion 34b, a fourth side portion 34a and a first corner portion 31b connected in sequence end to end, the third side portion 33a is arranged at an angle to the first side portion 31a, the second side portion 32a is arranged opposite to the first side portion 31a, and the fourth side portion 34a is arranged at an angle to the second side portion 32a, wherein the size of the fourth side portion 34a in the third direction Y may be larger than the size of the third side portion 33a in the third direction Y.

[0137] For example, the anti-shake bracket 30 may have a second through hole 301, which penetrates the anti-shake bracket 30 in the first direction Z. The second through hole 301 may be located between the first side portion 31a and the second side portion 32a, and between the third side portion 33a and the fourth side portion 34a. That is, the first side portion 31a, the second side portion 32a, the third side portion 33a and the fourth side portion 34a are arranged around the second through hole 301, and it is also considered that the second through hole 301 is located on the inner side of the anti-shake bracket 30.

[0138] Exemplarily, the first side portion 31a may be provided with a first through hole 311, which may penetrate the first side portion 31a in the second direction X to connect the inner side and the outer side of the anti-shake bracket 30; the second side portion 32a may be provided with a second through hole 321, which may penetrate the second side portion 32a in the second direction X and can also connect the inner side and the outer side of the anti-shake bracket 30.

[0139] Exemplarily, the fourth side portion 34a may be provided with a first mounting groove 341, and the first mounting groove 341 may be located between the first corner portion 31b and the fourth corner portion 34b.

[0140] Exemplarily, the second corner portion 32b may be provided with a first slide groove 361, and the fourth corner portion 34b may be provided with a second slide groove 362. The first slide groove 361 and the second slide groove 362 may be approximately considered to be at opposite ends of the anti-shake bracket 30, and the extension direction of the first slide groove 361 and the second slide groove 362 may be parallel to the first direction Z.

[0141] Exemplarily, the anti-shake bracket 30 may further include a positioning column 35, the number of which may be four, and the four positioning columns 35 may be respectively arranged on the first corner 31b, the second corner 32b, the third corner 33b and the fourth corner 34b, and protrude relative to the outer surfaces of the first corner 31b, the second corner 32b, the third corner 33b and the fourth corner 34b.

[0142] Fig.10 yes Figure 2 The schematic diagram of the partial structural breakdown of the motor 1 shown Figure 2 . Fig.11 yes Figure 2 The schematic cross-sectional structure diagram of a partial structure of the motor 1 is shown along DD.

[0143] like Fig.10 and Fig.11As shown, in some embodiments, the first magnetic member 24 can be fixed to the first side portion 31a and at least partially located in the first through hole 311. The first magnetic member 24 can be a magnet or other magnetic component. For example, the first magnetic member 24 can be fixedly connected to the first side portion 31a by gluing or other methods. The first magnetic member 24 is at least partially located in the first through hole 311. It can be considered that the first magnetic member 24 is partially embedded in the first through hole 311, or the entire first magnetic member 24 is embedded in the first through hole 311, which can be beneficial to improve the space utilization rate in the anti-shake bracket 30 and improve the compactness of the structural arrangement of the first magnetic member 24 and the anti-shake bracket 30. In the embodiment of the present application, the first magnetic member 24 is completely embedded in the first through hole 311 as an example for introduction. In other embodiments, the first through hole 311 may not be provided in the first side portion 31a, and the first magnetic member 24 can be fixed to the surface of the first side portion 31a. The present application does not limit this.

[0144] The shape of the first magnetic member 24 can be matched with the shape of the first through hole 311 to improve the tightness of the connection between the first magnetic member 24 and the first side portion 31a, and to make full use of the space in the first through hole 311. For example, when the first through hole 311 is arranged in a trapezoidal shape, the first magnetic member 24 can also be arranged in a trapezoidal shape. In other embodiments, when the first through hole 311 is arranged in a square shape, the first magnetic member 24 is also arranged in a square shape.

[0145] like Fig.10 and Fig.11 As shown, in some embodiments, the second magnetic member 25 can be fixed to the second side portion 32a and at least partially located in the second through hole 321. The second magnetic member 25 can be a magnet or other magnetic component. For example, the second magnetic member 25 can be fixedly connected to the second side portion 32a by gluing or other methods. The second magnetic member 25 is at least partially located in the second through hole 321. It can be considered that the second magnetic member 25 is partially embedded in the second through hole 321, or the entire second magnetic member 25 is embedded in the second through hole 321, which can be beneficial to improve the space utilization rate in the anti-shake bracket 30 and improve the compactness of the structural arrangement of the second magnetic member 25 and the anti-shake bracket 30. In the embodiment of the present application, the second magnetic member 25 is completely embedded in the second through hole 321 as an example for description. In other embodiments, the second through hole 321 may not be provided in the second side portion 32a, and the second magnetic member 25 can be fixed to the surface of the second side portion 32a, which is not limited in the present application.

[0146] The shape of the second magnetic member 25 can be adapted to the shape of the second through hole 321 to improve the tightness of the connection between the second magnetic member 25 and the second side portion 32a, and can also effectively utilize the space inside the second through hole 321. For example, when the second through hole 321 is trapezoidally arranged, the second magnetic member 25 can also be trapezoidally arranged. In other embodiments, when the second through hole 321 is square-shaped, the second magnetic member 25 is also square-shaped.

[0147] As Fig.10 and Fig.11 shown, in some embodiments, the third magnetic member 26 can be installed in the first installation groove 341 to be fixed to the fourth side portion 34a. Exemplarily, the third magnetic member 26 can be fixed to the groove wall and / or the bottom wall of the first installation groove 341 by means such as gluing. When the third magnetic member 26 is installed in the first installation groove 341, it can be considered that the third magnetic member 26 is partially embedded in the first installation groove 341, or the entire third magnetic member 26 is embedded in the first installation groove 341 and exposed relative to the first installation groove 341, which is beneficial to improving the space utilization rate inside the anti-shake bracket 30 and can improve the compactness of the structural arrangement of the third magnetic member 26 and the anti-shake bracket 30. The third magnetic member 26 can be a magnet or other magnetic components.

[0148] In this embodiment, the first magnetic member 24, the second magnetic member 25, and the third magnetic member 26 are respectively fixed to the first side portion 31a, the second side portion 32a, and the fourth side portion 34a of the anti-shake bracket 30, and all adopt a fitting structure of at least partial embedding, so that the arrangement structure between multiple components is compact and the space utilization rate is high. And the third side portion 33a of the anti-shake bracket 30 maintains a small size without other cooperating components being provided. For example, the width of the third side portion 33a is smaller than the width of the first side portion 31a and the width of the fourth side portion 34a, which is beneficial to reducing the volume of the anti-shake bracket 30.

[0149] As Fig.10 and Fig.11 shown, exemplarily, the motor 1 further includes a magnetic conduction member 54. The magnetic conduction member 54 can include a first plate member 541, a second plate member 542, a third plate member 543, and a fourth plate member 544. The second plate member 542, the third plate member 543, and the fourth plate member 544 are connected to the same side of the first plate member 541.

[0150] Among them, the first plate member 541 includes a first portion 5411, a second portion 5412, and a third portion 5413 connected in sequence. The first portion 5411 and the third portion 5413 are oppositely arranged. In this way, the first plate member 541 is generally in a "C" shape. The second plate member 542 is connected to the first portion 5411 of the first plate member 541. The third plate member 543 is connected to the second portion 5412 of the first plate member 541. The fourth plate member 544 is connected to the third portion 5413 of the first plate member 541.

[0151] The first plate 541, the second plate 542, the third plate 543 and the fourth plate 544 are all embedded in the anti-shake bracket 30, and the first portion 5411 of the first plate 541 is located at the bottom of the first magnetic member 24, and the second portion 5412 of the first plate 541 is located at the bottom of the third magnetic member 26. The third portion 5413 of the first plate 541 is located at the bottom of the second magnetic member 25. The second plate 542 is located at the periphery of the second magnetic member 25. The third plate 543 is located at the periphery of the third magnetic member 26. The fourth plate 544 is located at the periphery of the second magnetic member 25.

[0152] It can be understood that the first portion 5411 of the first plate 541 cooperates with the second plate 542 to enhance the magnetic field directivity of the first magnetic member 24. The second portion 5412 of the first plate 541 cooperates with the third plate 543 to enhance the magnetic field directivity of the third magnetic member 26. The first portion 5411 of the first plate 541 cooperates with the fourth plate 544 to enhance the magnetic field directivity of the second magnetic member 25.

[0153] Fig.12 yes Figure 2 The exploded view of the partial structure of the motor 1 is shown Figure 3 . Fig.13 yes Fig.12 The partial structure of the motor 1 shown is shown in FIG. Figure 3 . Fig.14 yes Fig.13 The cross-sectional structure diagram of a portion of the motor shown is taken along EE.

[0154] like Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments, the anti-shake bracket 30 can be movably connected to the base 10, and the anti-shake bracket 30 can be located between the first side plate 12 and the second side plate 13, the first side portion 31a is arranged opposite to the first side plate 12, the second side portion 32a is arranged opposite to the second side plate 13, the first corner portion 31b is arranged corresponding to the first fixing block 141, the second corner portion 32b is arranged corresponding to the third fixing block 143, the third corner portion 33b is arranged corresponding to the fourth fixing block 144, and the fourth corner portion 34b is arranged corresponding to the second fixing block 142. At this time, the first magnetic member 24 is arranged opposite to the first anti-shake coil 21, the second magnetic member 25 is arranged opposite to the second anti-shake coil 22, and the third magnetic member 26 is arranged opposite to the third anti-shake coil 23.

[0155] For example, at least a portion of the fourth side portion 34a can extend into the accommodating space 171, which is beneficial to improving the utilization rate of the space in the base 10 when the anti-shake bracket 30 is installed on the base 10, and can also improve the compactness of the arrangement of the anti-shake bracket 30 and the base 10, which is beneficial to miniaturization of the motor 1. At this time, the third magnetic member 26 is arranged opposite to the third anti-shake coil 23, and at least a portion of the third magnetic member 26 can extend into the accommodating space 171.

[0156] Exemplarily, the first through hole 110 and the second through hole 301 at least partially overlap. In other words, it can also be considered that the anti-shake bracket 30 and the base 10 are coaxially nested, which is beneficial to improve the compactness of the arrangement of structural parts in the motor 1, and can also improve the utilization rate of the space in the motor 1, which is conducive to realizing the miniaturization of the motor 1.

[0157] Exemplarily, the first end 551 of the elastic member 55 is fixedly connected to the fixed block 14, and the second ends 552 of the four elastic members 55 are fixedly connected to the four positioning posts 35 in a one-to-one correspondence. The positioning posts 35 can be inserted into the mounting holes 554 to realize the elastic connection between the elastic member 55 and the anti-shake bracket 30. When the anti-shake bracket 30 moves along the second direction X relative to the base 10, the four elastic members 55 will be elastically deformed, and the combined force direction of the restoring force generated by the four elastic members 55 is in the opposite direction of the movement of the anti-shake bracket 30 relative to the base 10, so as to drive the anti-shake bracket 30 to move in the opposite direction relative to the base 10, so that the anti-shake bracket 30 moves back to the equilibrium position, which can improve the linearity of the movement of the anti-shake bracket 30, and can also help to maintain the center of the anti-shake bracket 30 in the direction of the optical axis, thereby improving the reliability and control accuracy of the motor 1. In other embodiments, the first end 551 of the elastic member 55 can be used to overlap the anti-shake bracket 30, and the second ends 552 of the four elastic members 55 are used to be fixedly connected to the four fixed blocks 14 in a one-to-one correspondence. The present application is not limited to this. Alternatively, the positioning column 35 may not be provided on the anti-shake bracket 30, and the second end 552 of the elastic member 55 is fixed to the outer surface of the anti-shake bracket 30 by other means such as gluing.

[0158] For example, the anti-shake bracket 30 can be movably connected to the base 10 through the first ball group 181, the second ball group 182 and the third ball group 183, and the anti-shake bracket 30 is connected to the base 10 by rolling between the ball group 18 and the base 10, so as to realize the movably connected base 10 of the anti-shake bracket 30. In this embodiment, the ball group 18 plays a supporting role, which can reduce the friction resistance between the ball and the anti-shake bracket 30 while ensuring that sufficient supporting force is provided, thereby improving the smoothness of the movement process of the anti-shake bracket 30 movably connected to the base 10. In addition, the ball group 18 can provide multi-point support for the anti-shake bracket 30, which is conducive to dispersing stress, preventing the deformation of the ball when it is hit by a collision due to excessive concentration of force in a single direction, and improving the reliability of the ball group 18 supporting the anti-shake bracket 30 and other structural parts. In other embodiments, the motor 1 may not be provided with a ball group 18, but a sliding shaft is provided, and the relative sliding process between the anti-shake bracket 30 and the base 10 is realized by the sliding shaft, and the axial direction of the sliding shaft is the guiding direction of the sliding shaft.

[0159] Exemplarily, the first ball group 181, the second ball group 182 and the third ball group 183 can be arranged in a triangle. The first ball group 181, the second ball group 182 and the third ball group 183 can provide multi-point support for the anti-shake bracket 30, improve the stability of the relative position relationship between the anti-shake bracket 30 and the ball group 18, and make the movement of the anti-shake bracket 30 safer and more reliable. In this embodiment, the position of the ball group 18 is arranged according to the principle of triangle stability, which can ensure the reliability of the ball group 18 while reducing the number of ball groups 18 in the motor 1, which is conducive to simplifying the structure of the motor 1. In other embodiments, the ball group 18 may include the first ball group 181 and the second ball group 182, but not the third ball group 183; or, the ball group 18 may include the first ball group 181, the second ball group 182, the third ball group 183 and the fourth ball group 18, which is not limited in this application.

[0160] For example, the centers of the first ball group 181, the second ball group 182, and the third ball group 183 may be located in the direction of the optical axis of the lens 2. In this embodiment, the center of the anti-shake bracket 30 may also be located on the optical axis of the lens 2. In other words, the centers of the first ball group 181, the second ball group 182, and the third ball group 183 may be collinear with the center of the anti-shake bracket 30. At this time, it is also recorded that the anti-shake bracket 30 is in a balanced position relative to the base 10, which can avoid unnecessary losses and influences caused by the centers of the first ball group 181, the second ball group 182, and the third ball group 183 deviating from the center of the anti-shake bracket 30, such as the influence on the control accuracy of the motion process of the anti-shake bracket 30 relative to the base 10.

[0161] For example, the diameter of the balls of the ball group 18 may be less than or equal to 0.3 mm. At this time, the motor 1 in this embodiment can reduce the distance between the ball group 18 and the anti-shake bracket 30 while ensuring the supporting function of the balls, which is conducive to achieving the thinning and miniaturization of the motor 1.

[0162] Exemplarily, the friction coefficient between the ball group 18 and the base 10 can be less than or equal to 0.06, which is beneficial to minimize the friction resistance and possible friction heat generated during the sliding process of the ball within the effective limited stroke, thereby improving the wear resistance of the ball and extending its service life.

[0163] It can be understood that by reasonably configuring the relative positions of the first ball group 181, the second ball group 182 and the third ball group 183, as well as design parameters such as the number and diameter of the balls in each ball group 18, the friction coefficient between the balls of the ball group 18 and the base 10 can be less than or equal to 0.06.

[0164] Exemplarily, the anti-shake bracket 30 can be movably connected to the metal member 184 through at least two ball groups 18. By setting the ball group 18 to be rollingly connected between the metal member 184 and the anti-shake bracket 30, the friction force on the ball group 18 during rolling can be reduced, the degree of wear of the balls can be alleviated, the life of the balls can be extended, and the smoothness of the balls of the ball group 18 during rotation can be improved, which is beneficial to improving the movement rate of the anti-shake bracket 30 when the metal member 184 is movably connected through the ball group 18, and is beneficial to improving the response speed of the motor 1. The metal member 184 can be a material such as a steel sheet, which is not limited in this application. In addition, the ball group 18 is arranged in the groove 116 and contacts the metal member 184, which can also improve the compactness of the arrangement between the ball group 18 and the base 10, and can enhance the strength of the base 10 to prevent the base 10 from deforming.

[0165] For example, a lubricating part may be provided in the motor 1, for example, the lubricating part may be lubricating oil. By applying lubricating oil on the surface of the ball, the friction during the rolling of the ball can be effectively reduced, the noise during the rolling of the ball can be reduced, and the degree of wear of the ball can be alleviated. In other embodiments, the motor 1 may not include the metal part 184, and the motor 1 may not include the metal part 184 and the lubricating part, and this application does not limit this.

[0166] Fig.15 yes Figure 3 A schematic structural diagram of the focusing bracket 40 is shown.

[0167] like Fig.15As shown, the focus bracket 40 may be generally frame-shaped, and may include a first convex portion 41, a second convex portion 42, and a bracket body 43. A third through hole 430 may be provided in the bracket body 43. The first convex portion 41 and the second convex portion 42 may be located on opposite sides of the bracket body 43 and protrude relative to the outer surface of the bracket body 43. Exemplarily, the bracket body 43, the first convex portion 41, and the second convex portion 42 may together form an integrally formed structural member, which is not limited in the present application.

[0168] Exemplarily, the bracket body 43 may further be provided with a second mounting groove, a third mounting groove, a third slide groove 433 and a fourth slide groove 434. The third slide groove 433 and the fourth slide groove 434 are located on opposite sides of the third through hole 430, the third slide groove 433 is closer to the first protrusion 41 relative to the fourth slide groove 434, the second mounting groove and the third slide groove 433 are arranged at intervals and are located on the same side of the third through hole 430, the third mounting groove and the fourth slide groove 434 are arranged at intervals and are located on the same side of the third through hole 430, the extension direction of the third slide groove 433 and the fourth slide groove 434 may be parallel to the first direction Z, and the opening direction of the second mounting groove and the opening direction of the third mounting groove are both arranged away from the third through hole 430.

[0169] Fig.16 yes Figure 2 The partial structure of the motor 1 shown is shown in FIG. Figure 4 .

[0170] like Fig.15 and Fig.16 As shown, in some embodiments, the first focus coil 27 can be fixed to the first protrusion 41, and at least part of the first protrusion 41 is located in the first focus coil 27, and the second focus coil 28 can be fixed to the second protrusion 42, and at least part of the second protrusion 42 is located in the second focus coil 28. It can be understood that by setting at least part of the first protrusion 41 to be located in the first focus coil 27, the first protrusion 41 can effectively utilize the inner space of the first focus coil 27 while providing a certain support force to the first focus coil 27, thereby improving the compactness of the structural arrangement between the first focus coil 27 and the focus. In other embodiments, the focus bracket 40 may not include the first protrusion 41 and the second protrusion 42, and the first focus coil 27 and the second focus coil 28 can be fixed to the focus bracket 40 by providing a groove on the surface of the focus bracket 40. At this time, a groove can be formed on the surface of the focus bracket 40 and the first focus coil 27 and the second focus coil 28 can be disposed in the groove so that the first focus coil 27 and the second focus coil 28 are fixed to the focus bracket 40 .

[0171] Exemplarily, the motor 1 may further include a focusing magnetic member 432, which may be fixed to the focusing bracket 40. The focusing magnetic member 432 may be made of a material that can generate magnetic attraction with a magnet or other magnetic components, such as a ferromagnetic material.

[0172] The number of the focusing magnetic members 432 may be two, or any other number. The two focusing magnetic members 432 may have the same shape and size, and each focusing magnetic member 432 may have the same number. In other embodiments, the two focusing magnetic members 432 may have different shapes and sizes.

[0173] The two focusing magnetic components 432 can be installed in the second mounting groove and the third mounting groove respectively. The focusing magnetic components 432 can be installed in the second mounting groove and / or the third mounting groove by gluing or in-film injection molding, etc., and this application does not limit this.

[0174] Exemplarily, the motor 1 may further include a focus driver chip 45, which may be fixed to the focus bracket 40. During the movement of the focus bracket 40, the focus driver chip 45 may effectively, timely and accurately detect the position change of the focus bracket 40. In addition, the focus driver chip 45 may also be used for communication or data storage.

Fig.19 yes Fig.18 The schematic cross-sectional view of a partial structure of the motor 1 along line FF is shown.

[0176] like Fig.17 , Fig.18 and Fig.19 As shown, in some embodiments, the focus bracket 40 can be installed on the inner side of the anti-shake bracket 30. In this case, the third through hole 430 of the focus bracket 40 can be used to install the lens 2 (such as Figure 2 As shown in the figure, the central axis of the focus bracket 40 is parallel to the optical axis of the lens 2, and the third through hole 430 at least partially overlaps with the first through hole 110 and the second through hole 301. In other words, it can also be considered that the focus bracket 40, the anti-shake bracket 30 and the base 10 are coaxially nested, which is beneficial to improve the compactness of the arrangement of the structural parts in the motor 1, and can also improve the utilization rate of the space in the motor 1, which is conducive to realizing the miniaturization of the motor 1.

[0177] Exemplarily, the first focusing coil 27 may be disposed facing the first magnetic member 24 , and in the second direction X, the first anti-shake coil 21 , the first magnetic member 24 , and the first focusing coil 27 may be arranged in sequence.

[0178] The second focus coil 28 may be disposed facing the second magnetic member 25. Specifically, in the second direction X, the second focus coil 28, the second magnetic member 25 and the second anti-shake coil 22 may be arranged in sequence.

[0179] Exemplarily, the sliding shaft 52 can be made of a magnetic conductive material, and the focusing magnetic suction piece 432 can be arranged close to the sliding shaft 52 to generate a magnetic suction force with the sliding shaft 52, so that the focusing bracket 40 is adsorbed on the sliding shaft 52. It can be understood that the sliding shaft 52 can guide the movement process of the focusing bracket 40. By utilizing the magnetic suction force between the focusing magnetic suction piece 432 and the sliding shaft 52, the focusing bracket 40 can be tightly fitted with the sliding shaft 52, and the focusing bracket 40 can move along the extension direction of the sliding shaft 52, so as to avoid displacement of the focusing bracket 40 in other directions during the focusing process, thereby improving the reliability of the focusing process. In addition, the driving force when the focusing bracket 40 moves only needs to overcome its own gravity, the gravity of the lens 2, and the friction between the sliding shaft 52, and has no obvious correlation with the movement stroke, so that the focusing bracket 40 can achieve a large stroke movement in the first direction Z.

[0180] Exemplarily, the third slide groove 433 is arranged corresponding to the first slide groove 361, and the fourth slide groove 434 is arranged corresponding to the second slide groove 362. The first slide shaft 521 is installed in the third slide groove 433 and is at least partially embedded in the first slide groove 361, and the second slide shaft 522 is installed in the fourth slide groove 434 and is at least partially embedded in the second slide groove 362. One end of the slide shaft 52 can be fixedly connected to the anti-shake bracket 30 by bonding or screws. The focus bracket 40 is slidably connected to the anti-shake bracket 30 through the slide shaft 52, and the relative sliding direction of the two is parallel to the guide direction of the slide shaft 52, that is, the first direction Z. Among them, the axial direction of the slide shaft 52 is its guide direction. In other embodiments, the guide function can also be realized by using balls between the focus bracket 40 and the anti-shake bracket 30, and this application is not limited to this.

[0181] It can be understood that the inner wall of the third slide groove 433 can be adapted to the outer side surface of the first slide shaft 521. For example, when the outer surface of the first slide shaft 521 is arc-shaped, the inner surface of the third slide groove 433 is also arc-shaped to increase the contact area between the third slide groove 433 and the first slide shaft 521. It can also be considered that the third slide groove 433 and the first slide shaft 521 are tightly connected; the inner surface of the fourth slide groove 434 can be "L-shaped or V-shaped, etc.", which can reduce the processing difficulty of the focus bracket 40. It can also be considered that the fourth slide groove 434 is loosely connected to the second slide shaft 522. By setting the shapes of the surfaces of the third slide groove 433 and the fourth slide groove 434, a tight fit and loose fit design between the focus bracket 40 and the two slide shafts 52 can be achieved, so as to reduce the overall assembly difficulty while ensuring the degree of fit between the focus bracket 40 and the slide shaft 52.

[0182] Fig. 20 yes Figure 2 The partial structure of the motor 1 shown is shown in FIG. Figure 6 .

[0183] like Fig. 20 As shown, in some embodiments, the motor 1 further includes a reed 60, the arrangement plane of the reed 60 may be perpendicular to the first direction Z, and is located on the side of the focus bracket 40 that is away from the bottom plate 11. That is, the reed 60 may be arranged in the XY plane. The reed 60 may connect the focus bracket 40 and the base 10. Among them, the reed 60 has a certain deformation ability, and can deform when the focus bracket 40 moves relative to the anti-shake bracket 30 and leaves the equilibrium position, thereby ensuring the reliability of the connection between the reed 60 and the focus bracket 40 and the base 10. In some embodiments, the reed 60 may be made of conductive material to take into account the signal transmission function.

[0184] Fig.21 yes Figure 2 The partial structure of the motor 1 shown is shown in FIG. Figure 7 .

[0185] like Fig.21 As shown, in some embodiments, the pressure plate 50 can be fixed to the side of the anti-shake bracket 30 facing away from the bottom plate 11, and is used to limit the movement range of the focus bracket 40 in the first direction Z, prevent the focus bracket 40 from being separated from the anti-shake bracket 30, and ensure the reliability of the focus bracket 40 moving relative to the anti-shake bracket 30 along the first direction Z. The pressure plate 50 is provided with a fourth through hole 501, and a part of the structure of the focus bracket 40 is exposed through the fourth through hole 501.

[0186] Fig. 22 yes Figure 2 The schematic structural diagram of the motor 1 is shown in another perspective.

[0187] like Fig.21 and Fig. 22As shown, in some embodiments, the housing 51 can be covered on the base 10, and the housing 51 and the base 10 cooperate to form the outer contour of the motor 1, which can protect the internal structure of the motor 1. The housing 51 is provided with a fifth through hole 502, and part of the structure of the motor 1, such as the inner surface of the focus bracket 40, is exposed through the fifth through hole 502.

[0188] Fig.23 yes Fig. 22 The schematic diagram of the cross-sectional structure of the motor 1 cut along GG is shown. Fig.24 yes Fig.23 A simplified schematic diagram of the forces acting on the central structure.

[0189] like Fig.23 As shown, in some embodiments, the first focus coil 27 and the first magnetic member 24 may be correspondingly arranged to form a first focus drive group, and the first focus drive group may be used to drive the focus bracket 40 to move relative to the anti-shake bracket 30 along the first direction Z, so as to drive the lens 2 to move along the first direction Z, and realize the focusing function of the motor 1, wherein the first focus coil 27 is arranged corresponding to the first magnetic member 24, which means that the winding plane of the first focus coil 27 faces the first magnetic member 24. Exemplarily, the winding plane of the first focus coil 27 may be parallel to the first direction Z, and the first focus coil 27 is arranged vertically, which is conducive to reducing the size of the motor 1 in the second direction X, and realizing the miniaturization of the motor 1.

[0190] In this embodiment, during the movement of the focus bracket 40 relative to the anti-shake bracket 30 along the first direction Z, the first direction Z is perpendicular to the magnetic gap between the first magnetic member 24 and the first focus coil 27. The width of the magnetic gap is not affected by the movement of the focus bracket 40, and the first driving force F1 (the driving force in the motor 1 used to drive the focus bracket 40 to move relative to the anti-shake bracket 30 along the first direction Z) due to the change in the magnetic gap can be avoided. For example, the first driving force F1 will decrease rapidly when the magnetic gap increases, etc., which can effectively ensure the stability and reliability of the first driving force F1 of the motor 1, which is beneficial to the reliability of the focusing process of the motor 1.

[0191] like Fig.23As shown, illustratively, the first magnetic member 24 may include one or more magnets, and the implementation structure of the first magnetic member 24 may be multiple. For example, in some embodiments, the first magnetic member 24 may adopt a dual magnet solution, for example, it may be composed of two magnets, the two magnets may be a first magnet 241 and a second magnet 242, the first magnet 241 and the second magnet 242 may be arranged in a first direction Z, the polarity direction of the first magnet 241 is opposite to the polarity direction of the second magnet 242, and is parallel to the second direction X; in other embodiments, the first magnetic member 24 may be a Halbach magnet array. In other embodiments, the first magnetic member 24 may adopt a single magnet solution, for example, it may be composed of a magnet, the magnet includes two parts with opposite polarity directions, and the magnet may be made by a bipolar magnetization process.

[0192] like Fig.23 As shown, in some embodiments, the first anti-shake coil 21 and the first magnetic member 24 can be correspondingly arranged to form a first anti-shake drive group, and the first anti-shake drive group can be used to drive the anti-shake bracket 30 to drive the focus bracket 40 to move relative to the base 10 along the second direction X, so as to drive the lens 2 to move along the second direction X, thereby realizing the anti-shake function of the motor 1. Among them, the first focus drive group and the first anti-shake drive group can share the magnetic field generated by the first magnetic member 24, and the first magnetic member 24 can cooperate with the first focus coil 27 to control the movement of the focus bracket 40, and can also cooperate with the first anti-shake coil 21 to control the anti-shake bracket 30 to drive the focus bracket 40 to move. Exemplarily, the winding plane of the first anti-shake coil 21 can be parallel to the first direction Z. In other words, the first anti-shake coil 21 can be arranged vertically, which is conducive to reducing the size of the motor 1 in the second direction X and realizing the miniaturization of the motor 1.

[0193] The first anti-shake coil 21, the first magnetic member 24 and the first focusing coil 27 in the motor 1 in this embodiment are arranged in sequence in the second direction X. The motor 1 in this embodiment can save space in the first direction Z, and can also make full use of the space of the motor 1 in the first direction Z, which is beneficial to improving the utilization rate of the internal space of the motor 1, making the structure of the motor 1 more compact, and also beneficial to achieving the thinning and miniaturization of the motor 1. In addition, when the first magnetic member 24 is located between the first anti-shake coil 21 and the first focusing coil 27, the first magnetic member 24 can isolate the first anti-shake coil 21 and the first focusing coil 27, so as to avoid the magnetic fields generated by the first anti-shake coil 21 and the first focusing coil 27 after being energized from superimposing each other and interfering with each other, forming a crosstalk phenomenon, affecting the control accuracy of the focusing process and the anti-shake process, and thus affecting the reliability of the motor 1.

[0194] In other words, the motor 1 in this embodiment is an integrated motor 1 having both an anti-shake function and a focusing function, and the focusing bracket 40 is located on the inner side of the anti-shake bracket 30. Compared with a split motor in which the anti-shake bracket 30 and the focusing bracket 40 are separately arranged, the motor 1 in this embodiment is smaller in size and more compact in structure, which is conducive to reducing the size of the motor 1. At the same time, the motor 1 in this embodiment can control the focus bracket 40 to move relative to the anti-shake bracket 30 along the first direction Z by setting the first magnetic member 24, and can also control the anti-shake bracket 30 to move relative to the base 10 along the second direction X. Compared with the motor 1 that needs to set multiple groups of different magnetic members to cooperate with the focusing coil to control the focus bracket 40 to move along the first direction Z, and cooperate with the anti-shake coil to drive the anti-shake bracket 30 to move along the second direction X, the overall structure of the motor 1 in this embodiment is simpler and more compact, which is conducive to realizing the miniaturization of the motor 1. In addition, since the relative position of the anti-shake bracket 30 and the base 10 is not affected when the focusing bracket 40 moves relative to the anti-shake bracket 30 along the first direction Z, the relative position of the first anti-shake coil 21 and the first magnetic component 24 will not change. This can ensure that the width of the magnetic gap between the first anti-shake coil 21 and the first magnetic component 24 will not change when the focusing bracket 40 moves relative to the anti-shake bracket 30, which is beneficial to improving the reliability of the motor 1.

[0195] like Fig.23 As shown, illustratively, the second focus coil 28 and the second magnetic member 25 can be correspondingly arranged to form a second focus drive group, and the second focus drive group can also be used to drive the focus bracket 40 to move along the first direction Z relative to the anti-shake bracket 30, so as to drive the lens 2 to move along the first direction Z, thereby realizing the focusing function of the motor 1. By setting the first focus drive group and the second focus drive group, the carrying capacity of the motor 1 can be improved, so that the motor 1 can drive the lens 2 with a larger mass to realize its focusing process. Among them, the second focus coil 28 is arranged corresponding to the second magnetic member 25, which means that the winding plane of the second focus coil 28 faces the second magnetic member 25.

[0196] Exemplarily, the second magnetic member 25 may include one or more magnets, and the implementation structure of the second magnetic member 25 may be various. For example, in some embodiments, the second magnetic member 25 may adopt a dual magnet solution, for example, it may be composed of two magnets, and the two magnets may be arranged in the first direction Z, and the polarity directions are opposite; in other embodiments, the second magnetic member 25 may be a Halbach magnet array. In other embodiments, the second magnetic member 25 may adopt a single magnet solution, for example, it may be composed of a magnet, and the magnet includes two parts with opposite polarity directions, and the magnet may be made by a bipolar magnetization process. The second magnetic member 25 and the second focusing coil 28 may be designed the same or similarly to the first magnetic member 24 and the first focusing coil 27, so that the direction of the Ampere force generated by the second focus drive group is the same as that of the first focus drive group, and no further details will be given here.

[0197] In addition, the first focus driving group and the second focus driving group can be located on opposite sides of the focus bracket 40, and the accompanying forces of the first focus coil 27 and the second focus coil 28 can offset each other, thereby achieving more accurate driving action, and both opposite sides of the focus bracket 40 can be affected by the first driving force F1, which is also conducive to improving the stability and reliability of the focus bracket 40 when it moves relative to the anti-shake bracket 30. The accompanying force refers to the component of the magnetic force in the non-movement direction caused by the inclination of the edge magnetic field lines of the first magnetic member 24 or the second magnetic member 25.

[0198] Exemplarily, the second anti-shake coil 22 and the second magnetic member 25 can be correspondingly arranged to form a second anti-shake drive group, and the second anti-shake drive group can be used to drive the anti-shake bracket 30 to drive the focus bracket 40 to move relative to the base 10 along the second direction X, so as to drive the lens 2 to move along the second direction X, thereby realizing the anti-shake function of the motor 1. By setting the first anti-shake drive group and the second anti-shake drive group, the driving force in the motor 1 along the second direction X can be increased, so that the motor 1 can drive the lens 2 to realize the anti-shake process at a larger angle. Among them, the second focus drive group and the second anti-shake drive group can share the magnetic field generated by the second magnetic member 25, and the second magnetic member 25 can cooperate with the second focus coil 28 to control the movement of the focus bracket 40, and can also cooperate with the second anti-shake coil 22 to control the anti-shake bracket 30 to drive the focus bracket 40 to move.

[0199] like Fig.23As shown, illustratively, the second focus coil 28, the second magnetic member 25 and the second anti-shake coil 22 can also be arranged in sequence in the second direction X, which can save the space of the motor 1 in the first direction Z, and can also make full use of the space of the motor 1 in the first direction Z, which is beneficial to improving the utilization rate of the internal space of the motor 1, making the structure of the motor 1 more compact, and is beneficial to achieving the thinning and miniaturization of the motor 1. In addition, the second magnetic member 25 is located between the second anti-shake coil 22 and the second focus coil 28. The second magnetic member 25 can also isolate the second anti-shake coil 22 and the second focus coil 28, so as to avoid the magnetic fields generated by the second anti-shake coil 22 and the second focus coil 28 after being energized, which are superimposed on each other and interfere with each other, forming a crosstalk phenomenon, affecting the control accuracy of the focusing process and the anti-shake process, and thus affecting the reliability of the motor 1.

[0200] In this embodiment, by designing the relative position relationship and relative area of ​​the first focus coil 27, the first magnetic member 24 and the first anti-shake coil 21, when the first anti-shake coil 21, the first magnetic member 24 and the first focus coil 27 are all vertically arranged and arranged along the second direction X, the first magnetic member 24 can be reused, so that the first magnetic member 24 can cooperate with the first focus coil 27 to achieve the focusing function, and can also cooperate with the first anti-shake coil 21 to achieve the anti-shake function. The position relationship design between the second focus coil 28, the second magnetic member 25 and the second anti-shake coil 22 can refer to the position relationship design between the first focus coil 27, the first magnetic member 24 and the first anti-shake coil 21 described below, and will not be repeated here.

[0201] like Fig.23 As shown, illustratively, the first position sensor 531 fixed to the first side plate 12 and the second position sensor 532 fixed to the second side plate 13 can be used together to detect the position change of the anti-shake bracket 30 in the second direction X.

[0202] like Fig.23 As shown, illustratively, the anti-shake magnetic component 19 can be arranged facing the first magnetic component 24 and embedded in the bottom plate 11, and the magnetic force between the anti-shake magnetic component 19 and the first magnetic component 24 makes the anti-shake bracket 30 have a tendency to approach the bottom plate 11. The anti-shake magnetic component 19 can also be arranged facing the second magnetic component 25 and embedded in the bottom plate 11, and the magnetic force between the anti-shake magnetic component 19 and the second magnetic component 25 can also make the anti-shake bracket 30 have a tendency to approach the bottom plate 11. By setting the anti-shake magnetic component 19 and the first magnetic component 24 and the anti-shake magnetic component 19 and the second magnetic component 25 to cooperate, it can be ensured that the base 10 and the anti-shake bracket 30 maintain contact during the movement, and the anti-shake bracket 30 is prevented from moving along the first direction Z during the movement, which affects the reliability and control accuracy of the motor 1.

[0203] An implementation scheme of the motor 1 of the present application will be described in detail below in conjunction with relevant drawings. In other embodiments, the motor 1 may also have other implementation schemes.

[0204] like Fig.23 and Fig.24 , exemplarily, the first magnetic member 24 may be composed of two magnets, the two magnets may include a first magnet 241 and a second magnet 242 respectively, the first magnet 241 and the second magnet 242 are arranged in a first direction Z, the polarity direction of the first magnet 241 is opposite to the polarity direction of the second magnet 242, and is parallel to the second direction X, the first focusing coil 27 may include a first side 271 and a second side 272 arranged oppositely along the first direction Z, the first side 271 of the first focusing coil 27 is arranged oppositely to the first magnet 241, and the second side 272 of the first focusing coil 27 is arranged oppositely to the second magnet 242. It can be understood that the polarity direction may be a direction from the North Pole (N) to the South Pole (S), or a direction from the South Pole (S) to the North Pole (N). In the embodiment of the present application, the polarity direction of the first magnet 241 is the direction from the north pole (N) to the south pole (S), and the polarity direction of the second magnet 242 is the direction from the south pole (S) to the north pole (N). In other words, the side of the first magnetic member 24 facing the first focusing coil 27 may include the north pole (N) and the south pole (S), and the side of the first magnetic member 24 facing away from the first focusing coil 27 may include the south pole (S) and the north pole (N). In other embodiments, the polarity direction of the first magnet 241 may also be the direction from the south pole (S) to the north pole (N), and the polarity direction of the second magnet 242 may be the direction from the north pole (N) to the south pole (S), and the present application does not limit this.

[0205] When current is passed through the first focusing coil 27, the current flow direction of the first side 271 of the first focusing coil 27 can be opposite to the current flow direction of the second side 272 of the first focusing coil 27, and the polarity directions of the first magnet 241 and the second magnet 242 can be opposite, so that the Ampere force exerted on the first side 271 of the first focusing coil 27 in the magnetic field generated by the first magnet 241 and the Ampere force exerted on the second side 272 of the first focusing coil 27 in the magnetic field generated by the second magnet 242 can be in the same direction, and the combined force formed by the superposition can provide a larger first driving force F1 for the focusing process of the motor 1, which is beneficial to improving the driving efficiency and increasing the optical focusing stroke. In the embodiment of the present application, the example of passing a clockwise current through the first focusing coil 27 is used for introduction. Fig.16The circle with "×" in the middle indicates that the current flows in relative to the cross section, and the solid circle indicates that the current flows out relative to the cross section. Then, an Ampere force along the first direction Z will be formed on the first side 271 of the first focusing coil 27, and an Ampere force along the first direction Z will be formed on the second side 272 of the first focusing coil 27. Therefore, the direction of the resultant force of the Ampere force formed on the first focusing coil 27 will be parallel to the first direction Z, and can be used to drive the focusing bracket 40 to move along the first direction Z.

[0206] Exemplarily, the first anti-shake coil 21 may include a first sub-anti-shake coil 211 and a second sub-anti-shake coil 212, the first sub-anti-shake coil 211 faces the first magnet 241, and the second sub-anti-shake coil 212 faces the second magnet 242. In this embodiment, the first sub-anti-shake coil 211 faces the first magnet 241, and it can be considered that the first sub-anti-shake coil 211 and the first magnet 241 can maintain a positive relationship or a nearly positive relationship, and the projection of the first sub-anti-shake coil 211 along the second direction X is only located or almost only located in the first magnet 241. At this time, the resultant force of the Ampere force formed on the first sub-anti-shake coil 211 after being energized is zero, that is, the anti-shake bracket 30 will not move in the first direction Z relative to the base 10. At this time, the first sub-anti-shake coil 211 and the first magnetic part 24 can maintain a positive relationship, and the magnetic flux passing through the first sub-anti-shake coil 211 can be the maximum value, so that it can form a first electromagnet (the electromagnet here is recorded as the first electromagnet to distinguish it from the second electromagnet). Similarly, the resultant force of the Ampere force formed on the second sub-anti-shake coil 212 after being energized is zero, and a second electromagnet will also be formed.

[0207] In the embodiment of the present application, a counterclockwise current is passed through the first sub-anti-shake coil 211 as an example for introduction. The first sub-anti-shake coil 211 has a third side 2111 and a fourth side 2112 that are relatively arranged in the first direction Z. The fourth side 2112 is closer to the second sub-anti-shake coil 212 relative to the third side 2111. Then, the current direction of the third side 2111 of the first sub-anti-shake coil 211 flows in the negative direction of the third direction Y. An Ampere force along the negative direction of the first direction Z is formed on the third side 2111 of the first sub-anti-shake coil 211. The current direction of the fourth side 2112 of the first sub-anti-shake coil 211 is along the positive direction of the third direction Y. The first focusing line An Ampere force along the positive direction of the first direction Z is formed on the fourth side 2112 of the ring 27. Therefore, the resultant force of the Ampere force formed on the first sub-anti-shake coil 211 is zero. At this time, the first sub-anti-shake coil 211 can be regarded as a first electromagnet, and the polarity direction of the first electromagnet is parallel to the second direction X, from the south pole (S) toward the north pole (N). The side of the first electromagnet close to the first magnet 241 is the south pole (S), and the side of the first magnet 241 close to the first electromagnet is also the south pole (S). A repulsive force along the second direction X is generated between the first magnet and the first magnet 241, which can push the anti-shake bracket 30 to move along the second direction X relative to the base 10.

[0208] By setting the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 to correspond to the first magnet 241 and the second magnet 242 respectively, the driving force in the motor 1 that pushes the anti-shake bracket 30 to move in this embodiment can include the magnetic force between the first electromagnet and the first magnet 241 and the magnetic force between the second electromagnet and the second magnet 242. The magnetic force can be an attractive force or a repulsive force, which is beneficial to increase the size of the second driving force F2, improve the driving efficiency, and increase the optical anti-shake stroke.

[0209] Exemplarily, the current directions of the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 may be the same or different. Exemplarily, the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 may be arranged in series or in parallel, or they may be powered separately. Among them, the wire diameter, number of turns and other parameters of the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 may be set to the same value, or may be set to different values. The second magnet 242 and the second sub-anti-shake coil 212 may be designed the same or similarly to the first magnet 241 and the first sub-anti-shake coil 211, so that the directions of the driving forces generated by the second magnet 242 and the second sub-anti-shake coil 212 and the first magnet 241 and the first sub-anti-shake coil 211 are the same, and they will not be repeated here.

[0210] Exemplarily, the winding planes of the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 may be parallel to the first direction Z. By setting the winding planes of the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 to be parallel to the first direction Z, in other words, the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 are arranged vertically, which is conducive to reducing the size of the motor 1 in the second direction X, and is conducive to miniaturization of the motor 1.

[0211] Fig.25 yes Fig. 22 The cross-sectional structure diagram of the motor 1 shown is taken along HH.

[0212] like Fig.25 As shown, in some embodiments, the third magnetic component 26 is fixed to the anti-shake bracket 30, the third anti-shake coil 23 is fixed to the fixed plate 17, and the third anti-shake coil 23 is arranged facing the third magnetic component 26, and is used to drive the anti-shake bracket 30 to move along the third direction Y relative to the base 10, and the third magnetic component 26 and the third anti-shake coil 23 are arranged in the first direction Z. Among them, the third anti-shake coil 23 is arranged facing the third magnetic component 26, which means that the winding plane of the third anti-shake coil 23 faces the third magnetic component 26. For example, the winding plane of the third anti-shake coil 23 can be arranged parallel to the third direction Y. At this time, the third anti-shake coil 23 can be arranged horizontally, which is beneficial to reduce the size of the motor 1 in the first direction Z and realize the miniaturization of the motor 1. Exemplarily, the third position sensor 533 (see Fig.12 ) can be used to detect the position change of the anti-shake bracket 30 in the third direction Y.

[0213] In this embodiment, the third magnetic member 26 and the third anti-shake coil 23 cooperate to form a third anti-shake drive group, which can provide the lens 2 with the degree of freedom to move along the third direction Y, which is beneficial to improving the application range of the motor 1 and optimizing the anti-shake performance. In addition, by arranging the third anti-shake coil 23 and the third magnetic member 26 in the first direction Z, during the movement of the anti-shake bracket 30 relative to the base 10, the movement direction of the anti-shake bracket 30 can be perpendicular to the magnetic gap between the third magnetic member 26 and the third anti-shake coil 23. The above magnetic gap is not affected by the movement of the anti-shake bracket 30, so the problem of rapid decrease in driving force due to 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 of a large stroke.

[0214] The circuit arrangement between the motor 1 and the module circuit board 3 will be described in detail below in conjunction with the relevant drawings.

[0215] Fig.26 yes Fig.23 The diagram is a partial structural diagram of an embodiment of a circuit in which the focus driving chip 45 is electrically connected to an external structure.

[0216] like Fig.26 As shown, for example, the motor 1 may further include multiple wires 60a and multiple conductive springs 60b. For example, the multiple wires 60a may include a first wire 61, a second wire 62, a third wire 63, and a fourth wire 64. The multiple conductive springs 60b may include a first conductive spring 65, a second conductive spring 66, a third conductive spring 67, and a fourth conductive spring 68.

The first wiring 61, the second wiring 62, the third wiring 63 and the fourth wiring 64 may all be embedded in the focus bracket 40. In other embodiments, the positions of the first wiring 61, the second wiring 62, the third wiring 63 and the fourth wiring 64 are not specifically limited.

[0218] Exemplarily, the outgoing ends of the plurality of wires 60 a are exposed relative to the focus bracket 40 , and the incoming ends of the plurality of wires 60 a are embedded in the focus bracket 40 and electrically connected to the plurality of ports of the focus driving chip 45 in a one-to-one correspondence.
