The entire contents of which are incorporated by reference into this application. Technical Field

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

[0003] 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 the camera function and quality, and ensure image quality. However, traditional motors usually require two different drive mechanisms to drive the mover along the optical axis to achieve autofocus, and drive the mover along a plane perpendicular to the optical axis to achieve optical image stabilization. As a result, the motor is often large in size, which is not conducive to the miniaturization of the motor.

[0004] Summary of the Invention

[0005] 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.

[0006] In a first aspect, the present application provides a motor. The motor includes a base, an anti-shake bracket, a focusing bracket, a first magnetic component, a first focusing coil, and a first anti-shake coil. The anti-shake bracket is movably connected to the base; the focusing bracket is located on the inner side of the anti-shake bracket and is movably connected to the anti-shake bracket, and the focusing bracket is used to install the lens; the first magnetic component is fixed to the anti-shake bracket; the first focusing coil is fixed to the focusing bracket, and the first focusing coil is arranged facing the first magnetic component to drive the focusing bracket to move relative to the base in a first direction; 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 focusing bracket to move relative to the base in a second direction, and the second direction intersects with the first direction; the first anti-shake coil, the first magnetic component, and the first focusing coil are arranged in sequence in the second direction.

[0007] 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, the first direction can be considered to be parallel to the optical axis of the lens. In other embodiments, the first direction can also intersect with the optical axis of the lens, which is not limited in this application. 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 (i.e., 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.

[0008] In other words, the motor in this embodiment is an integrated motor that has 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 this 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 part in the motor in this 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 parts 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 this embodiment is simpler and more compact, which is conducive to the miniaturization of the motor.

[0009] In this embodiment, the first anti-shake coil, the first magnetic part and the first focusing coil in the motor are arranged in the second direction in sequence, 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 improving the utilization rate of the internal space of the motor, making the structure of the motor more compact, and also conducive to realizing the thinning and miniaturization of the motor.

[0010] Furthermore, the first magnetic element, located between the first anti-shake coil and the first focus coil, ensures the motor's focusing and anti-shake performance while improving motor reliability. Specifically, when the first magnetic element is located between the first anti-shake coil and the first focus coil, it isolates the first anti-shake coil from the first focus coil, preventing the magnetic fields generated by the first and second focus coils from overlapping and interfering with each other when energized, creating crosstalk that could affect the control accuracy of the focusing and anti-shake processes, thereby impacting the motor's reliability.

[0011] In one possible implementation, the winding planes of the first anti-shake coil and the first focus coil are both parallel to the first direction. In other words, the first anti-shake coil and the first focus coil are both arranged vertically, which helps reduce the size of the motor in the second direction and facilitates motor miniaturization.

[0012] In one possible implementation, the driving force for movement of the focus bracket in the first direction is the Ampere force generated on the first focus coil when the energized first focus coil is within the magnetic field of the first magnetic component. The driving force for movement of the anti-shake bracket in the second direction is the attractive or repulsive force between the electromagnet formed by the first anti-shake coil when energized and the first magnetic component and the electromagnet. In this case, the principle driving the movement of the focus bracket differs from the principle driving the movement of the anti-shake bracket, ensuring that the first magnetic component can be reused while the first anti-shake coil, the first magnetic component, and the first focus coil are arranged in the second direction. The first magnetic component can cooperate with the first focus coil to achieve both the focusing function and the anti-shake function.

[0013] In one possible implementation, the first magnetic element includes a first magnet and a second magnet, which are arranged in a first direction. The polarity of the first magnet is opposite to that of the second magnet and parallel to the second direction. The first anti-shake coil includes a first sub-anti-shake coil and a second sub-anti-shake coil, with the first sub-anti-shake coil facing the first magnet and the second sub-anti-shake coil facing the second magnet. In this embodiment, the first sub-anti-shake coil faces the first magnet. It can be assumed that the first anti-shake magnetic element and the second anti-shake magnetic element are directly or nearly directly opposite each other, and the projection of the first sub-anti-shake coil along the second direction is located only or nearly entirely within the first magnet. In this case, when power is applied to the first sub-anti-shake coil, the resultant Ampere force on the first sub-anti-shake coil is zero, the magnetic flux through the first sub-anti-shake coil is maximized, and the first sub-anti-shake coil forms a first electromagnet. Similarly, when power is applied to the second sub-anti-shake coil, the second electromagnet is also formed.

[0014] By configuring the first and second sub-anti-shake coils to correspond to the first and second magnets, respectively, the driving force within the motor that propels the anti-shake bracket in this embodiment can 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 can be either attractive or repulsive, which helps increase the driving force, improve driving efficiency, and extend the optical image stabilization travel. In other embodiments, the first magnetic member can also include a first sub-magnetic member and a second sub-magnetic member arranged in a first direction, with the first sub-magnetic member and the second sub-magnetic member having the same polarity arrangement and opposite polarity directions; alternatively, the first magnetic member can be a Halbach magnet array.

[0015] In one possible implementation, the winding planes of the first and second sub-anti-shake coils are both parallel to the first direction. By arranging the winding planes of the first and second sub-anti-shake coils parallel to the first direction, in other words, arranging the first and second sub-anti-shake coils vertically, the size of the motor in the second direction can be reduced, thereby facilitating motor miniaturization.

[0016] In one possible implementation, the first focusing coil includes a first side and a second side 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. The combined force can provide a greater driving force for the motor's focusing process, which is beneficial to improving driving efficiency and increasing the optical focusing stroke.

[0017] 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 member is fixed to the first edge portion, and the first anti-shake coil is fixed to the first side plate. In this case, the first edge portion can provide strength support for the first magnetic member, 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 member 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 structure such as a circuit board.

[0018] In one possible implementation, a first through-hole is provided on the first edge, connecting the inner and outer sides of the anti-shake bracket; the first magnetic member is at least partially located within the first through-hole. In this case, the first magnetic member and the anti-shake bracket are arranged compactly, thereby improving space utilization.

[0019] In one possible implementation, the base includes a second side plate connected to a surface of the bottom plate, the second side plate being located on a side of the anti-shake bracket away from the first side plate, the anti-shake bracket including a second edge portion, the second edge portion being disposed opposite the second side plate; the motor includes a second magnetic member and a second anti-shake coil; the second magnetic member 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 disposed facing the second magnetic member, thereby driving the anti-shake bracket to move the focus bracket in a second direction relative to the base. By arranging the second anti-shake coil in conjunction with the second magnetic member, the driving force within the motor in the second direction can be increased, enabling the motor to drive the lens to achieve anti-shake at a wider angle.

[0020] In one possible implementation, the motor further includes a second focus coil, secured to a side of the focus bracket facing away from the first focus coil. This second focus coil faces the second magnetic element, driving the focus bracket to move in the first direction relative to the base. The second focus coil, in conjunction with the second magnetic element, increases the driving force within the motor in the first direction, facilitating the focus bracket's ability to support a heavier lens and achieve focusing.

[0021] In one possible implementation, the motor further includes a third magnetic member and a third anti-shake coil. The third magnetic member is mounted on the anti-shake bracket, with the third anti-shake coil facing the third magnetic member. The third magnetic member is configured to drive the anti-shake bracket to move relative to the base in a third direction, which intersects both the first and second directions. The third anti-shake coil and the third magnetic member are arranged in the first direction. In this case, the third magnetic member and the third anti-shake coil cooperate to provide the lens with freedom of movement in the third direction, thereby expanding the motor's application range and optimizing anti-shake performance.

[0022] In addition, by arranging the third anti-shake coil and the third magnetic part in the first direction, when the anti-shake bracket moves relative to the base, the movement direction of the anti-shake bracket is perpendicular to the magnetic gap between the third magnetic part 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 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.

[0023] In one 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 achieving miniaturization of the motor.

[0024] In one possible implementation, the base includes a bottom plate, a first fixing block, a second fixing block, and a fixing plate. The first and second fixing blocks are fixed to the bottom plate with intervals therebetween. 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 and second fixing blocks, and the fixing plate enclose an accommodation space. The third anti-shake coil is fixed to the side of the fixing plate facing the accommodation space, and at least a portion of the third magnetic member extends into the accommodation space. In this configuration, the third anti-shake coil, the third magnetic member, and the base are arranged compactly, thereby improving space utilization.

[0025] In one possible implementation, the motor further includes a ball group mounted on a base, with the anti-shake bracket movably connected to the base via the ball group. Each ball group may include multiple balls, with the number of balls ranging from five, sixteen, to thirty-two, etc., though this application is not limited thereto. In this embodiment, the ball group is used to achieve a movable connection between the anti-shake bracket and the focus bracket. This ensures sufficient support force while reducing frictional resistance between the balls and the anti-shake bracket, thereby lowering the required driving force to drive the anti-shake bracket. This facilitates reducing the size of the first magnetic member and / or the first anti-shake coil, facilitating motor miniaturization. Furthermore, the smaller diameter of each ball within the ball group compared to a single ball also facilitates shortening the distance between the anti-shake bracket and the base, facilitating a thinner motor. Furthermore, the ball group provides multi-point support for the anti-shake bracket, distributing stress and preventing deformation of the balls due to excessive force concentration in a single direction during impact. This improves the reliability of the ball group's support of the anti-shake bracket and other structural components, such as the lens.

[0026] In one possible implementation, the ball group includes a first ball group, a second ball group, and a third ball group, arranged in a triangle. The first, second, and third ball groups provide multi-point support for the anti-shake bracket, improving the stability of the relative position between the anti-shake bracket and the ball group, making the movement of the anti-shake bracket safer and more reliable. In this embodiment, the ball group positions are arranged using the principle of triangular stability, ensuring reliability while reducing the number of ball groups within the motor, thereby simplifying the motor structure. In other embodiments, the ball group may not include the third ball group; alternatively, the ball group may include a fourth ball group, which is not limited in this application.

[0027] In one possible implementation, the centers of the first, second, and third ball groups are located along the optical axis 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, second, and third ball groups can be collinear with the center of the anti-shake bracket. This avoids unnecessary losses and impacts caused by the centers of the first, second, and third ball groups being offset from the center of the anti-shake bracket.

[0028] In one possible implementation, the diameter of the balls in the ball group is less than or equal to 0.3 mm. In this case, the motor in this embodiment can ensure the support function of the balls while reducing the distance between the ball group and the anti-shake bracket, which is conducive to achieving a thinner and smaller motor.

[0029] 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 balls within the effective limited stroke, and is beneficial to improving the wear resistance of the balls and extending their service life.

[0030] It is understandable that 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 balls in each ball group, the friction coefficient between the balls of the ball group and the base can be less than or equal to 0.06.

[0031] In one possible implementation, the motor further includes a metal member fixed to the base; the anti-shake bracket is movably connected to the metal member via at least two ball groups. The metal member may be a steel sheet, etc., and this application does not limit this. By providing the metal member and movably connecting the ball group to the metal member, the friction experienced by the ball group during movement can be reduced, improving the smoothness of the ball rotation, and facilitating the response rate of the anti-shake bracket when the ball group is movably connected to the metal member.

[0032] In one possible implementation, a metal component is embedded within the base, which has a groove through which the metal component is exposed relative to the base, and the ball group is located within the groove. By embedding the metal component within the base, the metal component provides a certain degree of rigidity and support to the base, enhancing its strength and preventing deformation. Furthermore, the ball group located within the groove and contacting the metal component reduces frictional resistance and improves the compactness of the arrangement between the ball group and the base, facilitating motor miniaturization.

[0033] In one 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 via the sliding shaft, and the sliding shaft is made of magnetic conductive material; the motor further includes a focus magnet, which is fixed to the focus bracket, and the focus magnet is arranged close to the sliding shaft to generate a magnetic attraction with the sliding shaft, and the magnetic attraction causes the focus bracket to be adsorbed on the sliding shaft. The sliding shaft can guide the movement of the focus bracket. By utilizing the magnetic attraction between the focus magnet 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 prevent 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 during the movement of the focus bracket only needs to overcome its own gravity, the gravity of the lens, and the friction between the slide shaft, and has no obvious correlation with the movement stroke, thereby achieving a large stroke movement of the focus bracket in the first direction.

[0034] In some possible embodiments, the motor further includes an anti-shake magnetic element secured to the base and positioned facing the first and second magnetic elements. The anti-shake magnetic element generates a magnetic attraction with the first and second magnetic elements, causing the anti-shake bracket to adhere to the base. The anti-shake magnetic element generates a magnetic attraction with the first and second magnetic elements, forcing the anti-shake bracket toward the base. This ensures contact between the base, the ball assembly, and the anti-shake bracket during movement, preventing the anti-shake bracket from moving in the first direction, which could affect the reliability and control accuracy of the motor.

[0035] In one possible implementation, the base includes a bottom plate and four fixed blocks, which are respectively fixed to 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 in a one-to-one correspondence, and the second ends of the four elastic members are fixedly connected to the four positions of the anti-shake bracket in a one-to-one correspondence. In other words, it can also be considered that the elastic members are fixedly connected to the four corners of the anti-shake bracket in a corresponding manner. By providing the elastic members, an elastic connection between the base and the anti-shake bracket can be achieved. When the anti-shake bracket moves in 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. This can improve the linearity of the anti-shake bracket's movement, and can also help maintain the center of the anti-shake bracket in the direction of the optical axis, thereby improving the reliability and control accuracy of the motor.

[0036] In one possible implementation, the fixing block has a receiving groove in which the middle portion of the elastic member is located. The motor also includes a damping rubber located in the receiving groove and wrapping around a portion of the middle portion of the elastic member. When the anti-shake bracket moves relative to the base, the middle portion of the elastic member is located in the receiving groove, and the damping rubber fills the groove, which helps suppress oscillations and provides better shock absorption and cushioning.

[0037] In one possible implementation, the fixed block includes side surfaces and a top and bottom surface disposed opposite each other, with the side surfaces connected between the top and bottom surfaces. The motor includes a conductive member, a portion of which is embedded within the fixed block. The elastic member is made of a conductive material, with a first end of the elastic member bent relative to a middle portion of the elastic member and connected thereto. The middle portion of the elastic member is opposed to and spaced from the side surfaces of the fixed block, and the first end of the elastic member is fixed to the conductive member. It is understood that the conductive member can typically be a wire or a flexible circuit board. In this case, the first end of the elastic member can contact the top surface of the fixed block, allowing the fixed block to provide a certain amount of support for the elastic member while the first end of the elastic member can be electrically connected to the conductive member. This avoids the need for the conductive member to be bent and improves the stability of the electrical connection within the motor.

[0038] In a possible implementation, the motor further 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. In this case, 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.

[0039] In a second aspect, embodiments of the present application further provide a camera module comprising a lens, an image sensor, and any of the aforementioned motors, wherein the lens is mounted within 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, has a simple and compact overall structure, and can achieve long-stroke image stabilization, thereby saving space within the camera module while ensuring high image quality.

[0040] In some possible embodiments, the camera module further includes a variable aperture located on the light-entering side of the lens. The variable aperture has an aperture whose size can be automatically adjusted. Light can enter the lens through the aperture of the variable aperture. The variable aperture is used to adjust the amount of light entering, allowing the camera module to maintain consistent image quality under various brightness conditions.

[0041] In one possible embodiment, 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.

[0042] In a third aspect, embodiments of the present application further provide an electronic device comprising a device housing and any of the aforementioned camera modules, the camera module being disposed within the device housing. The camera module features miniaturization and excellent image quality, which helps to conserve internal space of the electronic device while ensuring its image quality, thereby miniaturizing the electronic device.

[0073] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0074] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. "Moveable connection" means that the two components are connected to each other and can move relative to each other after connection. "Sliding connection" means that the two components are connected to each other and can slide relative to each other after connection. In addition, the integration of two components through an integrated molding process means that during the process of forming one of the two components, the component is connected to the other component without the need for further processing (such as bonding, welding, snap connection, screw connection) to connect the two components together.

[0079] FIG1 a is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0080] As shown in FIG1a , in some embodiments, electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 in the embodiment shown in FIG1a is described using a mobile phone as an example.

[0081] FIG1 b is a partial cross-sectional schematic diagram of the electronic device 1000 shown in FIG1 a taken along line AA in some embodiments.

[0082] As shown in Figures 1a and 1b, 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 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1a and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0083] The device housing 200 may include a frame 201 and a back cover 202, wherein the back cover 202 is fixed to the frame 201. For example, the back cover 202 may be fixed to the frame 201 by gluing, snapping, or the like. The back cover 202 may also be integrally formed with the frame 201, i.e., the back cover 202 and the frame 201 are a single unitary structure.

[0084] In some embodiments, the screen 300 can be located on the side of the frame 201 away from the back cover 202. In this case, the screen 300 and the back cover 202 can be located on either side of the frame 201. The screen 300, the frame 201, and the back cover 202 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, a receiver, or a microphone. The screen 300 can be flat or curved.

[0085] For example, the camera module 100 can be located inside the electronic device 1000. The camera module 100 can be located on the side of the screen 300 facing the back cover 202. The back cover 202 can have a light hole 203. The shape of the light hole 203 is not limited to the circular shape shown in Figure 1a. The light hole 203 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light hole 203. The camera module 100 can collect light entering the interior of the electronic device 1000.

[0086] FIG. 2 is a partially exploded schematic diagram of some embodiments of the camera module 100 shown in FIG. 1 a .

[0087] As shown in Figure 2, 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 components 5 can be components such as capacitors, inductors, resistors, or chips. Figure 2 schematically illustrates the electronic components 5 with a dotted frame.

[0088] It is understood that the camera module 100 may include fewer or more structures. For example, the camera module 100 may include fewer structures. For example, the camera module 100 may not include the electronic component 5, and / or the filter holder 6a, and / or the filter 6b, and / or the variable aperture 7.

[0089] It will be understood that, for ease of description, the camera module 100 will be 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, and 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 of the camera module 100 may be flexibly configured according to specific practical needs.

[0090] As shown in Figures 1b and 2, the image sensor 4 can be mounted on and electrically connected to the module circuit board 3. In this case, signals can be transmitted between the image sensor 4 and the module circuit board 3. Furthermore, the electronic component 5 is also mounted on and electrically connected to the module circuit board 3. In this case, signals can be transmitted between the electronic component 5 and the module circuit board 3.

[0091] For example, 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 passage 6c. A filter 6b is fixedly connected to the filter holder 6a. The filter 6b can be located within the light passage 6c. The filter 6b is also positioned opposite the image sensor 4. The filter 6b can be used to filter infrared light, blue light, and other light from light entering the image sensor 4, thereby ensuring that the image sensor 4 has excellent imaging quality.

[0092] As shown in Figure 1b, motor 1 is fixed to module circuit board 3. Motor 1 and image sensor 4 are located on the same side of module circuit board 3. Lens 2 is mounted on motor 1. Image sensor 4 is located on the light-emitting side of lens 2. It is understood that in the first direction Z, image sensor 4, filter 6b, and lens 2 are arranged in sequence. In this case, image sensor 4 is located on the light-emitting side of lens 2. Filter 6b is located between lens 2 and image sensor 4.

[0093] It is understood that the lens 2 can be used to collect ambient light. The optical axis direction of the lens 2 can be parallel to the 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.

[0094] 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.

[0095] 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 (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the lens 2 on the XY plane can be controlled by the motor 1 to offset the shaking stroke of the lens 2 on the XY plane to avoid or reduce the position offset of the lens 2 caused by the shaking. In other words, the camera module 100 of the present application can control the movement of the lens 2 on the XY plane by the motor 1 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100. The motor 1 can also be an integrated anti-shake and focus motor 1. In this way, the motor 1 can achieve 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 an example where the motor 1 is an anti-shake and focus integrated motor 1 .

[0096] As shown in FIG2 , the camera module 100 exemplarily includes a variable aperture 7. The variable aperture 7 can be located on the light-entering side of the lens 2. The variable aperture 7 has an aperture hole 7a, the size of which 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 consistent shooting quality under various brightness conditions.

[0097] The above briefly introduces the structure of the camera module 100 in conjunction with the relevant drawings, and the following will specifically introduce the structure of the motor 1 in conjunction with the relevant drawings.

[0098] FIG. 3 is a partially exploded schematic diagram 1 of some embodiments of the motor 1 shown in FIG. 2 .

[0099] As shown in FIG. 3 , 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 .

[0100] Illustratively, 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 .

[0101] For example, the number of the sliding shafts 52 may be two, or other numbers. For example, the sliding shafts 52 may include a first sliding shaft 521 and a second sliding shaft 522 .

[0102] FIG4 is a schematic diagram of a partial structure of the base 10 shown in FIG3 .

[0103] As shown in FIG4 , the base 10 may include a bottom plate 11, which may be substantially square in shape. The bottom plate 11 may include a first side region 111a, a second corner region 112b, a second side region 112a, a third corner region 113b, a third side region 113a, a fourth corner region 114b, a fourth side region 114a, and the first corner region 111b, connected end to end. The first side region 111a is arranged at an angle to the second side region 112a, the third side region 113a is arranged opposite to the first side region 111a, and the fourth side region 114a is arranged opposite to the second side region 112a. For example, the first side region 111a and the second side region 112a may be arranged perpendicular to each other, the third side region 113a may be parallel to the first side region 111a, and the fourth side region 114a may be parallel to the second side region 112a.

[0104] For example, a first through hole 110 may be provided in the bottom plate 11. The bottom plate 11 has a first surface 115 and a second surface (not shown in FIG. 4 ) that are oppositely disposed in the first direction Z. The first through hole 110 may penetrate the first surface 115 and the second surface. The first through hole 110 is located between the first side region 111a and the third side region 113a, and between the second side region 112a and the fourth side region 114a. That is, the first side region 111a, the second side region 112a, the third side region 113a, and the fourth side region 114a are disposed around the first through hole 110.

[0105] Exemplarily, the bottom plate 11 may further be provided with a plurality of grooves 116, which may be formed by the first surface 115 being recessed toward the interior of the bottom plate 11. The number of the plurality of grooves 116 may be three, and the three grooves 116 may include a first groove 1161, a second groove 1162, and a third groove 1163, respectively. The first groove 1161 and the second groove 1162 may be located in the second side region 112a, and the third groove 1163 may be located in the fourth side region 114a. The first groove 1161, the second groove 1162, and the third groove 1163 may be used to mount structural components within the motor 1. By providing a plurality of grooves 116 on the bottom plate 11 for mounting structural components, the structural components are at least partially embedded in the bottom plate 11, which can reduce the space occupied by the motor 1 in the first direction Z, and the structural components are compactly arranged, which can also improve the space utilization within the motor 1.

[0106] For example, the size of the opening of the first groove 1161 is the same as 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 openings of the first groove 1161, the second groove 1162, and the third groove 1163 can all be roughly elliptical. In other embodiments, the size, shape, or extension direction 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.

[0107] FIG5 is a schematic cross-sectional view of a portion of the base 10 shown in FIG4 taken along line BB.

[0108] As shown in FIG5 , a metal part 184 may be further provided in the base 10. The metal part 184 may be embedded in the bottom plate 11, and the metal part 184 may be exposed relative to the base 10 through the groove 116. For example, the metal part 184 may be embedded in the bottom plate 11, and exposed relative to the bottom plate 11 through the third groove 1163. The positional relationship between the metal part 184 and the first groove 1161, and the metal part 184 and the second groove 1162, may refer to the positional relationship between the metal part 184 and the third groove 1163 described above, and will not be repeated here. 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 may be located in the groove 116, which is not limited in this application.

[0109] As shown in Figures 4 and 5, for example, the base 10 may further include a first side panel 12, a second side panel 13 and four fixing blocks 14. The first side panel 12, the second side panel 13 and the four fixing blocks 14 are all fixed to the first surface 115. The four fixing blocks 14 may include a first fixing block 141, a second fixing block 142, a third fixing block 143 and a fourth fixing block 144. The first fixing block 141, the first side panel 12 and the third fixing block 143 may be connected in sequence to form an integrated structure. The first fixing block 141 may be arranged corresponding to the first corner area 111b, the first side panel 12 may be arranged corresponding to the first edge area 111a, and the third fixing block 143 may be arranged corresponding to the second corner area 112b. The first fixing block 141 and the first side panel 12 are arranged at an angle, and the third fixing block 143 and the first side panel 12 are arranged at an angle. The fourth fixing block 144, the second side panel 1 3 and the second fixing block 142 can be connected in sequence to form an integrated structure. The fourth fixing block 144 can be provided corresponding to the third corner area 113b, the second side panel 13 can be provided corresponding to the third edge area 113a, and the second fixing block 142 can be provided corresponding to the fourth corner area 114b. The fourth fixing block 144 and the second side panel 13 are provided at an angle, and the second fixing block 142 and the second side panel 13 are provided at an angle. The first fixing block 141 and the second fixing block 142 can be fixed to the bottom plate 11 at intervals. In other embodiments, the base 10 may not include four fixing blocks 14, or the base 10 may not include the first side panel 12 and / or the second side panel 13, or the number of fixing blocks 14 may be one, two, or three, etc., and this application is not limited thereto.

[0110] Exemplarily, the first fixed block 141 may include a top surface 1411, a bottom surface 1412, an outer side surface 1413 and an inner side surface 1414. The top surface 1411 of the first fixed block 141 and the bottom surface 1412 of the first fixed block 141 may be arranged back to back, the outer side surface 1413 of the first fixed block 141 and the inner side surface 1414 of the first fixed block 141 may be arranged back to back, the outer side surface 1413 of the first fixed block 141 and the inner side surface 1414 of the first fixed block 141 are both connected between the top surface 1411 of the first fixed block 141 and the bottom surface 1412 of the first fixed block 141, and the outer side surface 1413 of the first fixed block 141 is located on the side of the first fixed block 141 away from the first through hole 110. The second fixed block 142, the third fixed block 143 and the fourth fixed block 144 may also respectively include a top surface, a bottom surface, an outer side surface and an inner side surface. The positions of the top surface, the bottom surface, the outer side surface and the inner side surface in the corresponding second fixed block 142, the third fixed block 143 or the fourth fixed block 144 may refer to the positional relationship of the top surface 1411, the bottom surface 1412, the outer side surface 1413 and the inner side surface 1414 in the above-mentioned first fixed block 141, and this application will not elaborate on this.

[0111] For example, the fixing block 14 may further include a receiving slot 15. The receiving slot 15 may be fixed to the base plate 11 and located on the side of the fixing block 14 facing away from the first through-hole 110. The opening direction of the receiving slot 15 may be located on the same side of the base plate 11 as the first surface 115. For example, the receiving slot 15 may be located within a gap 1415 defined by the first surface 115 of the base plate 11, the outer side surface 1413 of the first fixing block 14, and the end surface of the first side plate 12. The bottom wall of the receiving slot 15 may be located on the first surface 115 of the base plate 11, and the sidewalls of the receiving slot 15 may be located on the outer side surface 1413 of the first fixing block 141. In the embodiment of the present application, there may be four receiving slots 15, each corresponding to one of the four fixing blocks 14. In other words, the positional relationship between the receiving slot 15 and the corresponding second fixing block 142, third fixing block 143, or fourth fixing block 144 may refer to the positional relationship between the receiving slot 15 and the first fixing block 141 described above, and this application will not further describe this.

[0112] Exemplarily, the base 10 may include an insulating body 16a and conductive members 16b. The conductive members 16b may be embedded in the insulating body 16a to form multiple transmission channels for signal transmission. The insulating body 16a may form the main body of the bottom plate 11, the first side plate 12, the second side plate 13, and the four fixing blocks 14. The number of conductive members 16b may be four, six, or another number. Multiple conductive members 16b may be arranged in the bottom plate 11, the first side plate 12, the second side plate 13, and / or the four fixing blocks 14.

[0113] One end of the conductive member 16b can be exposed relative to the end surface of the base 10 and used to electrically connect the structural members inside the motor 1. The other end of the conductive member 16b can be exposed relative to the surface of the base 10 and electrically connected to the module circuit board 3 (as shown in Figure 2). In other words, the conductive member 16b can be used as an electrical connection transmission channel between the structural members inside the motor 1 and the module circuit board 3.

[0114] For example, the end of the conductive member 16b may be exposed from the outer periphery of the bottom plate 11, the end of the conductive member 16b may be exposed from the first surface 115 of the bottom plate 11, the end of the conductive member 16b may be exposed from the top surface 1411 of the fixing block 14, the end of the conductive member 16b may be exposed from the inner surface of the first side plate 12, or the end of the conductive member 16b may also be exposed from the inner surface of the second side plate 13. In other embodiments, the exposed area of ​​the conductive member 16b relative to the base 10 can be set as needed, and this application is not limited to this.

[0115] FIG. 6 is a first schematic diagram of a partial structure of the motor 1 shown in FIG. 2 .

[0116] As shown in FIG6 , in some embodiments, the motor 1 may further include a ball group 18 . The ball group 18 may include a first ball group 181 , a second ball group 182 , and a third ball group 183 . Each ball group 18 may include multiple balls, and the number of balls may be five, sixteen, or thirty-two, etc., although this application is not limited thereto. The shape, number, and size of the balls within each ball group 18 may be identical or different. In this embodiment, the shape and size of each ball within the ball group 18 are identical, but the number of balls within the first ball group 181 , the second ball group 182 , and the third ball group 183 are different, although this application is not limited thereto. In other embodiments, the motor 1 may not include the second ball group 182 ; alternatively, the ball group 18 may include a fourth ball group, etc.

[0117] 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 may be located outside the first groove 1161.

[0118] In addition, the second ball group 182 can be disposed in the second groove 1162. The balls of the second ball group 182 can roll in the second groove 1162. Part of the balls of the second ball group 182 can be located in the second groove 1162, and part of the balls can be located outside the second groove 1162.

[0119] In addition, the third ball group 183 can be disposed in the third groove 1163. The balls of the third ball group 183 can roll in the third groove 1163. Part of the balls of the third ball group 183 can be located in the third groove 1163, and part of the balls can be located outside the third groove 1163.

[0120] For example, the first ball group 181 may be located in the first groove 1161 and contact the surface of the metal member 184, and roll in connection with the metal member 184. The second ball group 182 may be located in the second groove 1162 and contact the metal member 184, and roll in connection with the metal member 184. The third ball group 183 may be located in the third groove 1163 and contact the metal member 184, and roll in connection with the metal member 184.

[0121] FIG7 is an enlarged schematic diagram of the structure at point M in the motor 1 shown in FIG6 .

[0122] As shown in Figures 6 and 7 , in some embodiments, the motor 1 further includes an elastic member 55 that can be fixedly connected to the fixed block 14. For example, there can be four elastic members 55, each of which can be fixedly connected to the four fixed blocks 14 in a one-to-one correspondence. The four elastic members 55 can all have the same shape and size and can be numbered the same. It is understood that this application does not limit the number of elastic members 55.

[0123] 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.

[0124] 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, and 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. 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.

[0125] For example, the middle portion 553 of the elastic member 55 can be located in the receiving groove 15, and the receiving groove 15 can be filled with a damping material. The damping material can wrap at least a portion of the middle portion 553 of the elastic member 55. The damping material can be a material with a certain elastic deformation ability, which can play a role in oscillation suppression and can also play a role in shock absorption and buffering. For example, the damping material can be a damping glue such as rubber. When the elastic member 55 is deformed by an external force, the damping glue will also deform. A large internal friction will be generated in the damping glue, which absorbs and consumes 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 conducive to improving the reliability of the motor 1.

[0126] For example, the second end 552 of the elastic member 55 may be coplanar 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 .

[0127] As shown in Figure 6, in some embodiments, the base 10 may further include a fixing plate 17, one end of the fixing plate 17 may be fixed to the first fixing block 141, and the other end of the fixing plate 17 may be fixed to the second fixing block 142, and an accommodating space 171 may be enclosed between the bottom plate 11, the first fixing block 141, the second fixing block 142 and the fixing plate 17.

[0128] FIG8 is a schematic cross-sectional view of a portion of the motor 1 shown in FIG6 taken along CC.

[0129] As shown in Figures 6 and 8 , the first anti-shake coil 21 can be fixed to the side of the first side plate 12 facing the first through hole 110. In other embodiments, the base 10 may not include the first side plate 12. In this case, the first anti-shake coil 21 can be fixed between the first fixing block 141 and the third fixing block 143 using other structural components (such as a circuit board).

[0130] Exemplarily, the motor 1 may further include a first position sensor 531 , which may be fixed to the side of the first side plate 12 facing the first through hole 110 . The first position sensor 531 is used to realize position detection, and the first position sensor 531 may adopt a Hall sensor or a tunnel magnetoresistive sensor.

[0131] For example, the second anti-shake coil 22 can be fixed to the side of the second side plate 13 facing the first through hole 110. In other embodiments, the base 10 may not include the second side plate 13. The second anti-shake coil 22 can be fixed between the second fixing block 142 and the fourth fixing block 144 via other structural components (such as a circuit board).

[0132] Exemplarily, the motor 1 may further include a second position sensor 532 , which may be fixed to the side of the second side plate 13 facing the first through hole 110 . The second position sensor 532 is used to realize position detection, and the second position sensor 532 may adopt a Hall sensor or a tunnel magnetoresistive sensor.

[0133] For example, the third anti-shake coil 23 is fixed to the side of the fixing plate 17 facing the accommodating space 171. It is understood that there is a certain distance between the fixing plate 17 and the base plate 11. In other embodiments, the third anti-shake coil 23 may also be fixed to the side of the base plate 11 facing the accommodating space 171, which is not limited in this application.

[0134] For example, the motor 1 may further include a third position sensor 533, which may be fixed to the base plate 11 by providing a groove on the surface of the base plate 11 and placing the third position sensor 533 in the groove. The third position sensor 533 may be used to detect the position and may be a Hall sensor or a tunnel magnetoresistive sensor.

[0135] In some embodiments, the motor 1 further includes an anti-shake magnetic component 19, which can be fixed to the base plate 11. The anti-shake magnetic component 19 can be made of a material that can generate magnetic attraction with a magnet or other magnetic component, such as a ferromagnetic material. For example, the number of anti-shake magnetic components 19 can be four, and the shape and size of the four anti-shake magnetic components 19 can be the same. The four anti-shake magnetic components 19 can be labeled with the same number. It is understood that in other embodiments, the number, shape, and size of the anti-shake magnetic components 19 can be set as needed, and this application does not limit this.

[0136] For example, two anti-shake magnetic components 19 can be spaced apart in the first side region 111a, and another two anti-shake magnetic components 19 can be spaced apart in the third side region 113a. In this embodiment of the present application, the anti-shake magnetic components 19 are embedded in the bottom plate 11 as an example. In other embodiments, the anti-shake magnetic components 19 can be fixed to the bottom plate 11 and exposed relative to the first surface 115 of the bottom plate 11. This application is not limited to this.

[0137] FIG. 9 is a schematic structural diagram of the anti-shake bracket 30 shown in FIG. 3 .

[0138] As shown in Figure 8, the anti-shake bracket 30 may include a first side 31a, a second corner 32b, a third side 33a, a third corner 33b, a second side 32a, a fourth corner 34b, a fourth side 34a and a first corner 31b connected in sequence end to end. The third side 33a is arranged at an angle to the first side 31a, the second side 32a is arranged opposite to the first side 31a, and the fourth side 34a is arranged at an angle to the second side 32a. The dimension of the fourth side 34a in the third direction Y may be larger than the dimension of the third side 33a in the third direction Y.

[0139] For example, the anti-shake bracket 30 may have a second through-hole 301 that extends through the anti-shake bracket 30 in the first direction Z. The second through-hole 301 may be located between the first side 31a and the second side 32a, and between the third side 33a and the fourth side 34a. That is, the first side 31a, the second side 32a, the third side 33a, and the fourth side 34a surround the second through-hole 301, and the second through-hole 301 is considered to be located inside the anti-shake bracket 30.

[0140] For example, 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 also connect the inner side and the outer side of the anti-shake bracket 30.

[0141] Illustratively, 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 .

[0142] For example, the second corner portion 32b may further 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 located at opposite ends of the anti-shake bracket 30, and the extending direction of the first slide groove 361 and the second slide groove 362 may be parallel to the first direction Z. In other embodiments, the second corner portion 32b may be provided with a first slide groove 361, and the third corner portion 33b may be provided with a second slide groove 362. The first slide groove 361 and the second slide groove 362 may be located on the same side of the anti-shake bracket 30 and spaced apart. This application does not impose any specific limitation on this.

[0143] Exemplarily, the anti-shake bracket 30 may further include positioning posts 35, and the number of the positioning posts 35 may be four. The four positioning posts 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.

[0144] Fig. 10 is a second exploded schematic diagram of a portion of the motor 1 shown in Fig. 2. Fig. 11 is a schematic cross-sectional view of a portion of the motor 1 shown in Fig. 2 taken along line DD.

[0145] As shown in Figures 10 and 11, in some embodiments, the first magnetic member 24 can be fixed to the first side portion 31a and at least partially located within 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 fixed to the first side portion 31a by gluing or other methods. The first magnetic member 24 can be at least partially located within 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 first magnetic member 24 is fully embedded in the first through-hole 311. This can help improve space utilization within the anti-shake bracket 30 and enhance the compactness of the structural arrangement of the first magnetic member 24 and the anti-shake bracket 30. In the present embodiment, the first magnetic member 24 is completely embedded in the first through-hole 311. In other embodiments, the first through-hole 311 may not be provided within the first side portion 31a. The first magnetic member 24 can be fixed to the surface of the first side portion 31a. This is not limited in this application.

[0146] The shape of the first magnetic member 24 can be adapted to the shape of the first through hole 311 to enhance the tightness of the connection between the first magnetic member 24 and the first edge portion 31a and to fully utilize the space within the first through hole 311. For example, when the first through hole 311 is trapezoidal, the first magnetic member 24 can also be trapezoidal. In other embodiments, when the first through hole 311 is square, the first magnetic member 24 can also be square.

[0147] As shown in Figures 10 and 11, in some embodiments, the second magnetic member 25 can be fixed to the second edge portion 32a and at least partially located within 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 fixed to the second edge portion 32a by gluing or other methods. The second magnetic member 25 can be at least partially located within 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 second magnetic member 25 is entirely embedded in the second through-hole 321. This can help improve space utilization within the anti-shake bracket 30 and enhance the compactness of the structural arrangement of the second magnetic member 25 and the anti-shake bracket 30. In this embodiment, the second magnetic member 25 is completely embedded in the second through-hole 321. In other embodiments, the second edge portion 32a may not have the second through-hole 321, and the second magnetic member 25 can be fixed to the surface of the second edge portion 32a. This is not limited in this application.

[0148] 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 edge portion 32a and to effectively utilize the space within the second through hole 321. For example, when the second through hole 321 is arranged in a trapezoidal shape, the second magnetic member 25 can also be arranged in a trapezoidal shape. In other embodiments, when the second through hole 321 is arranged in a square shape, the second magnetic member 25 can also be arranged in a square shape.

[0149] As shown in Figures 10 and 11, in some embodiments, the third magnetic member 26 can be installed in the first mounting slot 341 to be fixed to the fourth edge portion 34a. For example, the third magnetic member 26 can be fixed to the slot wall and / or bottom wall of the first mounting slot 341 by gluing or other means. The third magnetic member 26 is installed in the first mounting slot 341. It can be considered that the third magnetic member 26 is partially embedded in the first mounting slot 341, or the third magnetic member 26 is embedded in the first mounting slot 341 and exposed relative to the first mounting slot 341. This helps to improve the space utilization within the anti-shake bracket 30 and can increase 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 component.

[0150] 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 at least partially embedded fitting structures, making the arrangement structure of multiple components compact and having a high space utilization rate. Without other fitting components provided, the third side portion 33a of the anti-shake bracket 30 maintains a small size. 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.

[0151] As shown in FIGS. 10 and 11, exemplarily, the motor 1 further includes a magnetic conductive member 54. The magnetic conductive member 54 may 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.

[0152] Among them, the first plate member 541 includes a first part 5411, a second part 5412, and a third part 5413 that are sequentially connected. The first part 5411 and the third part 5413 are disposed opposite to each other. In this way, the first plate member 541 is generally in a "C" shape. The second plate member 542 is connected to the first part 5411 of the first plate member 541. The third plate member 543 is connected to the second part 5412 of the first plate member 541. The fourth plate member 544 is connected to the third part 5413 of the first plate member 541.

[0153] The first plate member 541, the second plate member 542, the third plate member 543, and the fourth plate member 544 are all embedded in the anti-shake bracket 30. The first part 5411 of the first plate member 541 is located at the bottom of the first magnetic member 24. The second part 5412 of the first plate member 541 is located at the bottom of the third magnetic member 26. The third part 5413 of the first plate member 541 is located at the bottom of the second magnetic member 25. The second plate member 542 is located around the second magnetic member 25. The third plate member 543 is located around the third magnetic member 26. The fourth plate member 544 is located around the second magnetic member 25.

[0154] It can be understood that the first part 5411 of the first plate member 541 and the second plate member 542 cooperate with each other to enhance the magnetic field directivity of the first magnetic member 24. The second part 5412 of the first plate member 541 and the third plate member 543 cooperate with each other to enhance the magnetic field directivity of the third magnetic member 26. The first part 5411 of the first plate member 541 and the fourth plate member 544 cooperate with each other to enhance the magnetic field directivity of the second magnetic member 25.

[0155] Figure 12 is a third exploded schematic diagram of a portion of the motor 1 shown in Figure 2. Figure 13 is a third schematic diagram of a portion of the motor 1 shown in Figure 12. Figure 14 is a schematic cross-sectional view of a portion of the motor shown in Figure 13 taken along line EE.

[0156] As shown in Figures 12, 13, and 14, in some embodiments, the anti-shake bracket 30 can be movably connected to the base 10. The anti-shake bracket 30 can be located between the first side plate 12 and the second side plate 13. The first side 31a is disposed opposite the first side plate 12, the second side 32a is disposed opposite the second side plate 13, the first corner 31b is disposed corresponding to the first fixing block 141, the second corner 32b is disposed corresponding to the third fixing block 143, the third corner 33b is disposed corresponding to the fourth fixing block 144, and the fourth corner 34b is disposed corresponding to the second fixing block 142. In this case, the first magnetic member 24 is disposed opposite the first anti-shake coil 21, the second magnetic member 25 is disposed opposite the second anti-shake coil 22, and the third magnetic member 26 is disposed opposite the third anti-shake coil 23.

[0157] For example, at least a portion of the fourth edge 34a can extend into the accommodating space 171. This improves space utilization within the base 10 when the anti-shake bracket 30 is mounted on the base 10. It also increases the compactness of the arrangement of the anti-shake bracket 30 and the base 10, facilitating miniaturization of the motor 1. In this case, the third magnetic member 26 is positioned opposite the third anti-shake coil 23, and at least a portion of the third magnetic member 26 can extend into the accommodating space 171.

[0158] For example, 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 improving the compactness of the arrangement of the structural parts in the motor 1, and can also improve the utilization rate of the space in the motor 1, which is conducive to the miniaturization of the motor 1.

[0159] For example, 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, thereby achieving an elastic connection between the elastic member 55 and the anti-shake bracket 30. When the anti-shake bracket 30 moves in the second direction X relative to the base 10, the four elastic members 55 undergo elastic deformation. The combined restoring force generated by the four elastic members 55 is directed in the opposite direction of the movement of the anti-shake bracket 30 relative to the base 10, thereby driving the anti-shake bracket 30 to move in the opposite direction relative to the base 10, returning the anti-shake bracket 30 to a balanced position. This improves the linearity of the anti-shake bracket 30's movement and helps maintain the center of the anti-shake bracket 30 along the optical axis, thereby enhancing 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. This 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.

[0160] For example, the anti-shake bracket 30 can be movably connected to the base 10 via a first ball group 181, a second ball group 182, and a third ball group 183. The anti-shake bracket 30 is movably connected to the base 10 through the rolling connection between the ball group 18 and the base 10. In this embodiment, the ball group 18 provides support, ensuring sufficient support force while reducing friction between the balls and the anti-shake bracket 30, thereby improving the smoothness of the movement of the anti-shake bracket 30 in connection with the base 10. Furthermore, the ball group 18 provides multi-point support for the anti-shake bracket 30, which helps disperse stress and prevents excessive force concentration in a single direction, which could cause deformation of the balls during impact. This improves the reliability of the ball group 18's support of the anti-shake bracket 30 and other structural components. In other embodiments, the motor 1 may not include a ball group 18, but instead include a sliding shaft to facilitate relative sliding between the anti-shake bracket 30 and the base 10. The axial direction of the sliding shaft serves as the guide direction of the sliding shaft.

[0161] For example, the first ball group 181, the second ball group 182, and the third ball group 183 can be arranged in a triangle. These three groups can provide multi-point support for the anti-shake bracket 30, improving the stability of the relative position between the anti-shake bracket 30 and the ball group 18, making the movement of the anti-shake bracket 30 safer and more reliable. Furthermore, in this embodiment, the arrangement of the ball groups 18, utilizing the principle of triangular stability, ensures the reliability of the ball groups 18 while reducing the number of ball groups 18 within the motor 1, thereby 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. This is not a limitation in this application.

[0162] For example, the centers of the first ball group 181, the second ball group 182, and the third ball group 183 may be located along 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. In this case, the anti-shake bracket 30 is said to be in a balanced position relative to the base 10. This avoids 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 being offset from the center of the anti-shake bracket 30, such as an impact on the control accuracy of the motion of the anti-shake bracket 30 relative to the base 10.

[0163] For example, the diameter of the balls in the ball group 18 can be less than or equal to 0.3 mm. In this case, the motor 1 in this embodiment can ensure the supporting function of the balls while reducing the distance between the ball group 18 and the anti-shake bracket 30, thereby achieving a thinner and smaller motor 1.

[0164] For example, the friction coefficient between the ball group 18 and the base 10 can be less than or equal to 0.06, which is beneficial for minimizing the friction resistance and friction heat that may be generated during the sliding process of the balls within the effective limited stroke, thereby improving the wear resistance of the balls and extending their service life.

[0165] 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.

[0166] For example, the anti-shake bracket 30 can be movably connected to the metal part 184 through at least two ball groups 18. By setting the ball group 18 to be rollingly connected between the metal part 184 and the anti-shake bracket 30, the friction force on the ball group 18 during rolling can be reduced, the degree of wear on the balls can be alleviated, the life of the balls can be extended, and the smoothness of the balls in the ball group 18 during rotation can be improved. This is conducive to increasing the movement rate of the anti-shake bracket 30 when it is movably connected to the metal part 184 through the ball group 18, which is conducive to improving the response speed of the motor 1. The metal part 184 can be a material such as a steel sheet, and this is not limited in this application. In addition, the ball group 18 is arranged in the groove 116 and contacts the metal part 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 and prevent deformation of the base 10.

[0167] For example, a lubricant, such as lubricating oil, may be provided within the motor 1. By applying lubricating oil to the surface of the balls, friction during ball rolling can be effectively reduced, noise during rolling can be reduced, and wear on the balls can be alleviated. In other embodiments, the motor 1 may not include the metal member 184, or may not include both the metal member 184 and the lubricant. This application is not limited to this.

[0168] FIG15 is a schematic structural diagram of the focusing bracket 40 shown in FIG3 .

[0169] As shown in FIG15 , the focus bracket 40 may be generally frame-shaped and include a first protrusion 41, a second protrusion 42, and a bracket body 43. The bracket body 43 may include a third through-hole 430. The first protrusion 41 and the second protrusion 42 may be located on opposite sides of the bracket body 43 and protrude relative to the outer surface of the bracket body 43. For example, the bracket body 43, the first protrusion 41, and the second protrusion 42 may collectively form an integrally formed structural member, which is not limited in this application.

[0170] For example, the bracket body 43 may further be provided with a second mounting groove, a third mounting groove, a third sliding groove 433, and a fourth sliding groove 434. The third sliding groove 433 and the fourth sliding groove 434 are located on opposite sides of the third through hole 430. The third sliding groove 433 is closer to the first protrusion 41 than the fourth sliding groove 434. The second mounting groove and the third sliding groove 433 are spaced apart and located on the same side of the third through hole 430. The third mounting groove and the fourth sliding groove 434 are spaced apart and located on the same side of the third through hole 430. The extension direction of the third sliding groove 433 and the fourth sliding groove 434 may be parallel to the first direction Z. 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.

[0171] FIG16 is a fourth schematic diagram of the partial structure of the motor 1 shown in FIG2 .

[0172] As shown in Figures 15 and 16, in some embodiments, the first focus coil 27 can be fixed to the first protrusion 41, with at least a portion of the first protrusion 41 located within the first focus coil 27. The second focus coil 28 can be fixed to the second protrusion 42, with at least a portion of the second protrusion 42 located within the second focus coil 28. It will be appreciated that by positioning at least a portion of the first protrusion 41 within the first focus coil 27, the first protrusion 41 can provide sufficient support to the first focus coil 27 while effectively utilizing the space inside the first focus coil 27, thereby improving the compactness of the structural arrangement between the first focus coil 27 and the focus bracket 40. In other embodiments, the focus bracket 40 may not include the first protrusion 41 and the second protrusion 42. The first and second focus coils 27 and 28 can be fixed to the focus bracket 40 by, for example, providing grooves 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 placed in the groove so that the first focus coil 27 and the second focus coil 28 are fixed to the focus bracket 40 .

[0173] 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.

[0174] The number of the focusing magnetic members 432 can be two, or any other number. The two focusing magnetic members 432 can be of the same shape and size, and each focusing magnetic member 432 can have the same number. In other embodiments, the two focusing magnetic members 432 can have different shapes and sizes.

[0175] The two focusing magnetic parts 432 can be installed in the second mounting groove and the third mounting groove respectively. The focusing magnetic parts 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.

[0176] For example, 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 can effectively, promptly, and accurately detect position changes of the focus bracket 40. Furthermore, the focus driver chip 45 can also serve functions such as communication or data storage.

[0177] Fig. 17 is a fourth exploded schematic diagram of a portion of the structure of the motor 1 shown in Fig. 2. Fig. 18 is a fifth schematic diagram of a portion of the structure of the motor 1 shown in Fig. 17. Fig. 19 is a schematic cross-sectional diagram of a portion of the structure of the motor 1 shown in Fig. 18 along line FF.

[0178] As shown in Figures 17, 18 and 19, in some embodiments, the focusing bracket 40 can be installed on the inner side of the anti-shake bracket 30. At this time, the third through hole 430 of the focusing bracket 40 can be used to install the lens 2 (as shown in Figure 2). The central axis of the focusing 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 focusing 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 beneficial to achieve the miniaturization of the motor 1.

[0179] For example, the first focusing coil 27 may be arranged 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.

[0180] 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.

[0181] For example, the sliding shaft 52 can be made of a magnetic conductive material, and the focusing magnetic element 432 can be arranged close to the sliding shaft 52 to generate a magnetic attraction 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 play a guiding role in the movement process of the focusing bracket 40. By utilizing the magnetic attraction between the focusing magnetic element 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, thereby avoiding the focusing bracket 40 from being displaced 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, thereby realizing a large stroke movement of the focusing bracket 40 in the first direction Z.

[0182] Illustratively, the third slide groove 433 is provided corresponding to the first slide groove 361, and the fourth slide groove 434 is provided corresponding to the second slide groove 362. The first slide shaft 521 is mounted in the third slide groove 433 and at least partially embedded in the first slide groove 361. The second slide shaft 522 is mounted in the fourth slide groove 434 and 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 means of adhesive or screws. The focus bracket 40 is slidably connected to the anti-shake bracket 30 via the slide shaft 52, and the relative sliding direction between the two is parallel to the guide direction of the slide shaft 52, i.e., the first direction Z. The axial direction of the slide shaft 52 is its guide direction. In other embodiments, ball bearings can also be used to provide a guide function between the focus bracket 40 and the anti-shake bracket 30, but this application is not limited to this.

[0183] It is understood that the inner wall of the third slot 433 can be adapted to the outer surface of the first slide shaft 521. For example, when the outer surface of the first slide shaft 521 is curved, the inner surface of the third slot 433 is also curved to increase the contact area between the third slot 433 and the first slide shaft 521. The third slot 433 and the first slide shaft 521 can also be considered to be tightly connected. The inner surface of the fourth slot 434 can be "L-shaped or V-shaped, etc." to reduce the difficulty of manufacturing the focus bracket 40. The fourth slot 434 can also be considered to be loosely connected to the second slide shaft 522. By setting the shapes of the surfaces of the third slot 433 and the fourth slot 434, tight and loose fit designs can be achieved between the focus bracket 40 and the two slide shafts 52, thereby ensuring the fit between the focus bracket 40 and the slide shafts 52 while reducing the overall assembly difficulty.

[0184] FIG20 is a sixth schematic diagram of the partial structure of the motor 1 shown in FIG2 .

[0185] As shown in Figure 20, in some embodiments, the motor 1 further includes a reed 60. The arrangement plane of the reed 60 can be perpendicular to the first direction Z and located on the side of the focus bracket 40 facing away from the base plate 11. That is, the reed 60 can be arranged in the XY plane. The reed 60 can connect the focus bracket 40 and the base 10. The reed 60 has a certain degree of deformation capability and can deform when the focus bracket 40 moves relative to the anti-shake bracket 30 and leaves the equilibrium position, ensuring the reliability of the connection between the reed 60, the focus bracket 40 and the base 10. In some embodiments, the reed 60 can be made of a conductive material to ensure signal transmission.

[0186] FIG21 is a seventh schematic diagram of the partial structure of the motor 1 shown in FIG2 .

[0187] As shown in FIG21 , in some embodiments, a pressure plate 50 can be fixed to a side of the anti-shake bracket 30 facing away from the base plate 11 to limit the range of motion of the focus bracket 40 in the first direction Z, preventing the focus bracket 40 from separating from the anti-shake bracket 30 and ensuring reliable movement of the focus bracket 40 relative to the anti-shake bracket 30 in the first direction Z. The pressure plate 50 is provided with a fourth through hole 501 through which a portion of the structure of the focus bracket 40 is exposed.

[0188] FIG22 is a schematic structural diagram of the motor 1 shown in FIG2 from another perspective.

[0189] As shown in Figures 21 and 22, in some embodiments, a housing 51 can be mounted on the base 10. The housing 51 and the base 10 together form the outer contour of the motor 1 and protect the internal structure of the motor 1. The housing 51 defines a fifth through-hole 502, through which portions of the motor 1, such as the inner surface of the focus bracket 40, are exposed.

[0190] FIG23 is a schematic diagram of the cross-sectional structure of the motor 1 shown in FIG22 taken along GG, and FIG24 is a simplified schematic diagram of the force of a part of the structure in FIG23 .

[0191] As shown in FIG23 , 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. 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, thereby driving the lens 2 to move along the first direction Z and realizing the focusing function of the motor 1. 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. For example, 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 miniaturization of the motor 1.

[0192] In this embodiment, during the movement of the focusing 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 focusing coil 27. The width of the above-mentioned magnetic gap is not affected by the movement of the focusing bracket 40, and the first driving force F1 (the driving force in the motor 1 used to drive the focusing bracket 40 to move relative to the anti-shake bracket 30 along the first direction Z) can be avoided from being affected by the change in the magnetic gap. For example, when the magnetic gap increases, the first driving force F1 will decrease rapidly, 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.

[0193] As shown in FIG23 , illustratively, the first magnetic member 24 may include one or more magnets, and the first magnetic member 24 may have various implementation structures. For example, in some embodiments, the first magnetic member 24 may adopt a dual-magnet solution, for example, consisting of two magnets, which 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, with the polarity of the first magnet 241 being opposite to that of the second magnet 242 and 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, consisting of a single magnet including two parts with opposite polarity directions, which may be manufactured using a bipolar magnetization process.

[0194] As shown in Figure 23, in some embodiments, the first anti-shake coil 21 and the first magnetic member 24 can be configured to form a first anti-shake drive group. The first anti-shake drive group can be used to drive the anti-shake bracket 30 to move the focus bracket 40 relative to the base 10 in the second direction X, thereby driving the lens 2 in the second direction X, thereby achieving the anti-shake function of the motor 1. The first focus drive group and the first anti-shake drive group can share the magnetic field generated by the first magnetic member 24. 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. For example, 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 helps reduce the size of the motor 1 in the second direction X and achieve miniaturization of the motor 1.

[0195] In the present embodiment, the first anti-shake coil 21, the first magnetic member 24, and the first focusing coil 27 within the motor 1 are sequentially arranged in the second direction X. The motor 1 in the present embodiment can save space in the first direction Z and can also fully utilize 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, thereby preventing the magnetic fields generated by the first anti-shake coil 21 and the first focusing coil 27 after being energized from superimposing on 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.

[0196] In other words, the motor 1 in this embodiment is an integrated motor 1 that performs both stabilization and focusing functions, with the focus bracket 40 located inside the stabilization bracket 30. Compared to separate motors in which the stabilization bracket 30 and the focus bracket 40 are separately mounted, the motor 1 in this embodiment is smaller and more compact, facilitating a reduction in size. Furthermore, the motor 1 in this embodiment, through the provision of a first magnetic member 24, can control the movement of the focus bracket 40 relative to the stabilization bracket 30 in a first direction Z, as well as in a second direction X relative to the base 10. Compared to motors 1 that require multiple sets of magnetic members, each of which cooperates with the focus coil to control movement of the focus bracket 40 in the first direction Z and with the stabilization coil to drive movement of the stabilization bracket 30 in the second direction X, the motor 1 in this embodiment has a simpler and more compact overall structure, facilitating 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.

[0197] As shown in Figure 23, for example, the second focus coil 28 and the second magnetic member 25 can be arranged correspondingly to form a second focus drive group. 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 up 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 larger lens 2 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.

[0198] 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 with opposite polarity directions; 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 using 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.

[0199] Furthermore, the first and second focus drive groups can be located on opposite sides of the focus bracket 40, respectively. The accompanying forces of the first and second focus coils 27 and 28 can offset each other, thereby achieving more accurate driving. Furthermore, both opposing sides of the focus bracket 40 can be affected by the first driving force F1, which also helps improve the smoothness and reliability of the focus bracket 40's movement relative to the anti-shake bracket 30. The accompanying force refers to the component of the magnetic force in the non-moving direction caused by the tilted magnetic field lines at the edges of the first magnetic member 24 or the second magnetic member 25.

[0200] For example, the second anti-shake coil 22 and the second magnetic member 25 can be configured to form a second anti-shake drive group. 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 in the second direction X, thereby driving the lens 2 to move in the second direction X, thereby realizing the anti-shake function of the motor 1. By providing the first anti-shake drive group and the second anti-shake drive group, the driving force in the second direction X within the motor 1 can be increased, allowing the motor 1 to drive the lens 2 to achieve anti-shake at a wider angle. The second focus drive group and the second anti-shake drive group can share the magnetic field generated by the second magnetic member 25. 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.

[0201] As shown in FIG23 , for example, the second focusing 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 space on the motor 1 in the first direction Z and fully utilize the space on the motor 1 in the first direction Z, thereby improving the utilization rate of the internal space of the motor 1, making the structure of the motor 1 more compact, and facilitating 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 focusing coil 28. The second magnetic member 25 can also isolate the second anti-shake coil 22 and the second focusing coil 28, preventing the magnetic fields generated by the second anti-shake coil 22 and the second focusing coil 28 from overlapping and interfering with each other after power is applied, thereby 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.

[0202] In this embodiment, the relative positional relationship and relative areas of the first focus coil 27, the first magnetic member 24, and the first anti-shake coil 21 are designed so that when the first anti-shake coil 21, the first magnetic member 24, and the first focus coil 27 are all vertically disposed and arranged along the second direction X, the first magnetic member 24 can be reused, allowing the first magnetic member 24 to cooperate with the first focus coil 27 to achieve both a focusing function and an anti-shake function. The positional relationship between the second focus coil 28, the second magnetic member 25, and the second anti-shake coil 22 can be referenced to the positional relationship between the first focus coil 27, the first magnetic member 24, and the first anti-shake coil 21 described below, and will not be further described here.

[0203] As shown in FIG. 23 , for example, a first position sensor 531 fixed to the first side plate 12 and a second position sensor 532 fixed to the second side plate 13 can be used together to detect position changes of the anti-shake bracket 30 in the second direction X.

[0204] As shown in FIG23 , for example, the anti-shake magnetic component 19 can be disposed facing the first magnetic component 24 and embedded in the base plate 11. The magnetic force between the anti-shake magnetic component 19 and the first magnetic component 24 causes the anti-shake bracket 30 to tend to approach the base plate 11. The anti-shake magnetic component 19 can also be disposed facing the second magnetic component 25 and embedded in the base plate 11. The magnetic force between the anti-shake magnetic component 19 and the second magnetic component 25 can also cause the anti-shake bracket 30 to tend to approach the base plate 11. By arranging 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, it is possible to ensure that the base 10 and the anti-shake bracket 30 maintain contact during movement, thereby preventing the anti-shake bracket 30 from moving along the first direction Z during movement, which would affect the reliability and control accuracy of the motor 1.

[0205] 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.

[0206] As shown in Figures 23 and 24 , for example, the first magnetic member 24 may be composed of two magnets, which 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 opposite each other along the first direction Z. The first side 271 of the first focusing coil 27 is arranged opposite to the first magnet 241, and the second side 272 of the first focusing coil 27 is arranged opposite to the second magnet 242. It will be understood that the polarity direction may be a direction from the north pole (N) to the south pole (S), or vice versa. In the embodiment of the present application, the polarity direction of the first magnet 241 is from the north pole (N) to the south pole (S), and the polarity direction of the second magnet 242 is 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 a north pole (N) and a south pole (S), and the side of the first magnetic member 24 facing away from the first focusing coil 27 may correspondingly include a south pole (S) and a north pole (N). In other embodiments, the polarity direction of the first magnet 241 may also be from the south pole (S) to the north pole (N), and the polarity direction of the second magnet 242 may be from the north pole (N) to the south pole (S), and this application is not limited to this.

[0207] 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 within 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 within the magnetic field generated by the second magnet 242 can be in the same direction. The superimposed force can provide a greater first driving force F1 for the focusing process of the motor 1, which is beneficial to improving 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 description. The circles with "×" in Figure 16 represent the inflow of current relative to the cross section, and the solid circles represent the outflow of current relative to the cross section. 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 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.

[0208] For example, 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. It can be assumed that the first sub-anti-shake coil 211 and the first magnet 241 are directly opposite or nearly directly opposite each other, and the projection of the first sub-anti-shake coil 211 along the second direction X is located only or nearly only within the first magnet 241. At this time, the resultant force of the Ampere force formed on the first sub-anti-shake coil 211 after power is turned on is zero, that is, the anti-shake bracket 30 will not move relative to the base 10 in the first direction Z. 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 power is turned on is zero, and a second electromagnet will also be formed.

[0209] In the embodiment of the present application, the 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 close 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 along 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 is generated on the fourth side 2112 of the coil 27 in the positive direction of the first direction Z. Therefore, the resultant Ampere force generated 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 relative to the base 10 in the second direction X.

[0210] 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, in this embodiment, the driving force in the motor 1 that pushes the anti-shake bracket 30 to move 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 magnitude of the second driving force F2, improve the driving efficiency, and increase the optical anti-shake stroke.

[0211] Exemplarily, the current directions of the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 can be the same or different. Exemplarily, the first sub-anti-shake coil 211 and the second sub-anti-shake coil 212 can be arranged in series or in parallel, or they can 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 can be set to the same value, or they can be set to different values. The second magnet 242 and the second sub-anti-shake coil 212 can 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 no further details will be given here.

[0212] For example, the winding planes of the first and second anti-shake sub-coils 211, 212 can be parallel to the first direction Z. By arranging the winding planes of the first and second anti-shake sub-coils 211, 212 parallel to the first direction Z, in other words, the first and second anti-shake sub-coils 211, 212 are arranged vertically, which helps reduce the size of the motor 1 in the second direction X and facilitates miniaturization of the motor 1.

[0213] FIG25 is a schematic diagram of the cross-sectional structure of the motor 1 shown in FIG22 taken along line HH.

[0214] As shown in FIG25 , in some embodiments, the third magnetic member 26 is fixed to the anti-shake bracket 30, and the third anti-shake coil 23 is fixed to the fixing plate 17. The third anti-shake coil 23 is arranged facing the third magnetic member 26, and is used to drive the anti-shake bracket 30 to move relative to the base 10 along the third direction Y. The third magnetic member 26 and the third anti-shake coil 23 are arranged in the first direction Z. The third anti-shake coil 23 is arranged facing the third magnetic member 26, which means that the winding plane of the third anti-shake coil 23 faces the third magnetic member 26. For example, the winding plane of the third anti-shake coil 23 can be arranged parallel to the third direction Y. In this case, the third anti-shake coil 23 can be arranged horizontally, which helps reduce the size of the motor 1 in the first direction Z and achieve miniaturization of the motor 1. For example, the third position sensor 533 (see FIG12 ) can be used to detect position changes of the anti-shake bracket 30 in the third direction Y.

[0215] 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 provides the lens 2 with freedom of movement along the third direction Y, thereby expanding the application range of the motor 1 and optimizing anti-shake performance. Furthermore, 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. This magnetic gap is unaffected by the movement of the anti-shake bracket 30, thereby avoiding the problem of a rapid decrease in driving force due to an increased magnetic gap. Furthermore, a large anti-shake driving force can be maintained while maintaining driving force stability, facilitating anti-shake designs with long travel ranges.

[0216] The circuit arrangement between the motor 1 and the module circuit board 3 will be described in detail below with reference to the relevant drawings.

[0217] FIG. 26 is a partial structural diagram of an embodiment of a circuit in which the focus driving chip 45 shown in FIG. 23 is electrically connected to an external structure.

[0218] As shown in FIG26 , the motor 1 may further include, for example, 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 multiple conductive springs 60b may be an implementation of the reed 60 shown in FIG3 in the previous embodiment. In other words, the reed 60 may include multiple conductive springs 60b.

[0219] For example, multiple traces 60a can be embedded in the focus bracket 40 (as shown in FIG15 ) at intervals. For example, the first trace 61, the second trace 62, the third trace 63, and the fourth trace 64 can all be conductive traces. The first trace 61, the second trace 62, the third trace 63, and the fourth trace 64 can all be embedded in the focus bracket 40. In other embodiments, the positions of the first trace 61, the second trace 62, the third trace 63, and the fourth trace 64 are not specifically limited.

[0220] Exemplarily, the outgoing ends of the multiple wires 60 a are exposed relative to the focus bracket 40 , and the incoming ends of the multiple wires 60 a are embedded in the focus bracket 40 and electrically connected to the multiple ports of the focus driver chip 45 in a one-to-one correspondence.

[0221] For example, the output end 61b of the first trace 61 (as shown in FIG15 ) can be exposed relative to the surface of the focus bracket 40. The input end 61a of the first trace 61 can be electrically connected to the SDA signal terminal of the focus driver chip 45. It is understood that the SDA signal terminal can be used to transmit the serial data (SDA) signal of the I2C signal.

[0222] For example, the output end 62b of the second trace 62 (as shown in FIG15 ) can be exposed relative to the surface of the focus bracket 40. The input end 62a of the second trace 62 can be electrically connected to the SCL signal terminal of the focus driver chip 45. The output end 62b of the second trace 62 can be exposed relative to the top surface of the focus bracket 40 and spaced apart from the output end 61b of the first trace 61 near the side of the second protrusion 42 (as shown in FIG15 ). It will be understood that the SCL signal terminal can be used to transmit the serial clock (SCL) signal of the I2C signal.

[0223] For example, the output end 63b of the third trace 63 (as shown in FIG15 ) may be exposed relative to the surface of the focus bracket 40 . The input end 63a of the third trace 63 may be electrically connected to the positive power terminal of the focus driver chip 45 .

[0224] For example, the outgoing end 64b of the fourth trace 64 (as shown in FIG. 15 ) can be exposed relative to the surface of the focus bracket 40. The incoming end 64a of the fourth trace 64 can be electrically connected to the negative power supply terminal of the focus driver chip 45. The outgoing end 64b of the fourth trace 64 can be exposed relative to the top surface of the focus bracket 40 and spaced apart from the outgoing end 63b of the third trace 63, both near one side of the first protrusion 41 (as shown in FIG. 15 ).

[0225] In other embodiments, the first trace 61, the second trace 62, the third trace 63, and the fourth trace 64 may also be formed of flexible circuit boards. The first trace 61, the second trace 62, the third trace 63, and the fourth trace 64 may also be integrated into one flexible circuit board.

[0226] In some embodiments, the first conductive spring 65, the second conductive spring 66, the third conductive spring 67, and the fourth conductive spring 68 can all be metal spring structures and can deform under stress, thus exhibiting a stretchable effect. For example, multiple conductive springs 60b can be fixed to the anti-shake bracket 30 at intervals. For example, the first conductive spring 65, the second conductive spring 66, the third conductive spring 67, and the fourth conductive spring 68 can all be disposed on the top surface of the anti-shake bracket 30. It will be appreciated that the first conductive spring 65, the second conductive spring 66, the third conductive spring 67, and the fourth conductive spring 68 can utilize the dimensions of the XY plane of the motor 1. This allows the first conductive spring 65, the second conductive spring 66, the third conductive spring 67, and the fourth conductive spring 68 to be disposed over a larger area, thereby achieving a smaller reaction force.

[0227] Exemplarily, the conductive spring clip 60b can have an input end and an output end. The input end of the conductive spring clip 60b can be electrically connected to the output ends of the multiple traces 60a in a one-to-one correspondence, and the output end of the conductive spring clip 60b can be electrically connected to the external structure in a one-to-one correspondence. In this case, the input ends of the multiple conductive spring clips 60b are electrically connected to the focus driver chip 45 through the multiple traces 60a in a one-to-one correspondence. In other words, the multiple conductive spring clips 60b can respectively serve as transmission channels for the signals of each port of the focus driver chip 45, and external structures such as the module circuit board 3 (as shown in Figure 2) can be electrically connected to the focus driver chip 45 by electrically connecting the conductive spring clips 60b.

[0228] For example, the input end 65a of the first conductive spring 65 can be electrically connected to the output end 61b of the first trace 61. In this case, the first conductive spring 65 can be electrically connected to the SDA signal terminal of the focus driver chip 45 through the first trace 61. The input end 66a of the second conductive spring 66 can be electrically connected to the output end 62b of the second trace 62. In this case, the second conductive spring 66 can be electrically connected to the SCL signal terminal of the focus driver chip 45 through the second trace 62. The input end 67a of the third conductive spring 67 can be electrically connected to the output end 63b of the third trace 63. In this case, the third conductive spring 67 can be electrically connected to the positive power supply terminal of the focus driver chip 45 through the third trace 63. The input end 68a of the fourth conductive spring 68 can be electrically connected to the output end 64b of the fourth trace 64. In this case, the fourth conductive spring 68 can be electrically connected to the negative power supply terminal of the focus driver chip 45 through the fourth trace 64.

[0229] The input end 65a of the first conductive spring 65 can be fixedly connected to the output end 61b of the first trace 61 by welding or conductive adhesive. The connection method between the input end 66a of the second conductive spring 66 and the output end 62b of the second trace 62, the connection method between the input end 67a of the third conductive spring 67 and the output end 63b of the third trace 63, and the connection method between the input end 68a of the fourth conductive spring 68 and the output end 64b of the fourth trace 64 can refer to the connection method between the input end 65a of the first conductive spring 65 and the output end 61b of the first trace 61, and will not be repeated here.

[0230] For example, the first conductive spring 65 can also serve as a transmission channel for the SDA signal of the driver chip of the variable aperture 7 (as shown in FIG. 2 ). The second conductive spring 66 can serve as a transmission channel for the SCL signal of the driver chip of the variable aperture 7. The third conductive spring 67 can serve as a transmission channel for the positive power supply of the driver chip of the variable aperture 7. The fourth conductive spring 68 can serve as a transmission channel for the negative power supply of the driver chip of the variable aperture 7. In other words, the conductive spring 60b can also serve as a transmission channel for signals from various ports of the variable aperture 7. External structures such as the module circuit board 3 (as shown in FIG. 2 ) can be electrically connected to the variable aperture 7 by electrically connecting the conductive spring 60b.

[0232] As shown in Figure 27, exemplarily, the multiple conductive parts 16b may include a first conductive part 161, a second conductive part 162, a third conductive part 163, a fourth conductive part 164, a fifth conductive part 165 and a sixth conductive part 166. The above-mentioned multiple conductive parts 16b can all be conductive traces, or they can respectively adopt flexible circuit board structures, which is not limited in this application.

[0233] Exemplarily, the first conductive member 161 can be embedded in the first fixed block 141 and the first side panel 12, one end of the first conductive member 161 can be exposed relative to the top surface 1411 of the first fixed block 141, and the other end of the first conductive member 161 can be electrically connected to the module circuit board 3 (as shown in Figure 2).

[0234] Exemplarily, the second conductive member 162 can be embedded in the third fixed block 143 and the first side panel 12, one end of the second conductive member 162 can be exposed relative to the top surface 1411 of the third fixed block 143, and the other end of the second conductive member 162 can be electrically connected to the module circuit board 3 (as shown in Figure 2).

[0235] Exemplarily, the third conductive member 163 can be embedded in the fourth fixed block 144 and the second side panel 13, one end of the third conductive member 163 can be exposed relative to the top surface 1411 of the fourth fixed block 144, and the other end of the third conductive member 163 can be electrically connected to the module circuit board 3 (as shown in Figure 2).

[0237] Exemplarily, the fifth conductive member 165 can be embedded in the second fixed block 142 and the second side plate 13, one end of the fifth conductive member 165 can be exposed relative to the top surface 1411 of the second fixed block 142, and the other end of the fifth conductive member 165 can be electrically connected to the module circuit board 3 (as shown in Figure 2).

[0238] Exemplarily, the sixth conductive member 166 can be embedded in the first fixed block 141 and the first side panel 12, one end of the sixth conductive member 166 can be exposed relative to the top surface 1411 of the first fixed block 141, and the other end of the sixth conductive member 166 can be electrically connected to the module circuit board 3 (as shown in FIG. 2 ).

[0239] FIG28 is a schematic structural diagram of an embodiment of a circuit in which the motor 1 shown in FIG2 is electrically connected to an external structure.

[0240] As shown in Figures 27 and 28, the conductive member 16b can serve as a transmission channel between the conductive spring 60b and the module circuit board 3. In this case, one end of the multiple conductive members 16b can be electrically connected to the output ends of the multiple conductive springs 60b in a one-to-one correspondence to achieve electrical connection between the focus driver chip 45 or the variable aperture 7 and the module circuit board 3. Specifically, one end of the multiple conductive members 16b can contact the output ends of the multiple conductive springs 60b in a one-to-one correspondence to achieve electrical connection. Alternatively, one end of the multiple conductive members 16b can also be electrically connected to the output ends of the multiple conductive springs 60b through other structural members, such as the elastic member 55.

[0241] As shown in FIG28 , for example, the elastic member 55 can be made of a conductive material, and the first end 551 of the elastic member 55 can be fixed to the outlet end of the conductive spring 60 b. In this case, the first end 551 of the elastic member 55 can contact the top surface 1411 of the fixing block 14, allowing the fixing block 14 to provide a certain amount of support for the elastic member 55 while also electrically connecting the first end 551 of the elastic member 55 to the conductive spring 60 b. This avoids bending the conductive spring 60 b and improves the stability and reliability of the electrical connection within the motor 1.

[0242] Specifically, in the embodiment of the present application, the first ends 551 of the four elastic members 55 can be connected to the first conductive member 161, the second conductive member 162, the third conductive member 163, and the fourth conductive member 164, respectively.

[0243] In some embodiments, the conductive member 16b can also serve as a transmission channel between other structural components within the motor 1, such as the fixing plate 17, and the module circuit board 3. For example, the fixing plate 17 can be made of a conductive material, and its two ends can be fixed to one end of the multiple conductive members 16b, respectively, so that the module circuit board 3 can supply power to the third anti-shake coil 23 through the conductive members 16b and the fixing plate 17. Specifically, the opposite ends of the fixing plate 17 can be electrically connected to the fifth conductive member 165 and the sixth conductive member 166.
