Technical Field

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

[0003] With the widespread adoption and development of electronic devices such as smartphones and tablets, mobile photography has become a common method of photography, and users are increasingly demanding higher quality photography from their devices. When users are shooting, electronic devices are prone to shaking, which seriously affects the quality of the images. Therefore, camera modules often require an anti-shake mechanism. However, the anti-shake mechanism in current camera modules is relatively large, hindering the overall miniaturization of the camera module. Summary of the Invention

[0004] The embodiments of the present application provide an anti-shake motor, a camera module, and an electronic device, aiming to provide a smaller anti-shake motor, a camera module including the anti-shake motor, and an electronic device including the camera module.

[0005] In a first aspect, an anti-shake motor is provided. The anti-shake motor includes:

[0006] A fixed bracket having a mounting space for mounting an optical element;

[0007] Movable base, movably connected to the fixed bracket;

[0008] A photosensitive component is fixed to the movable base, the photosensitive component includes an image sensor and a sensor circuit board, the image sensor is fixed to the sensor circuit board, and the image sensor faces the installation space; and

[0009] A first driving mechanism includes a first coil and a first magnetic member, one of the first coil and the first magnetic member is fixed to the fixed bracket, and the other is fixed to the movable base, the first coil and the first magnetic member are arranged opposite to each other, and the first coil and the first magnetic member cooperate to drive the movable base to move relative to the fixed bracket in a first direction;

[0010] Among them, the first coil and the photosensitive component are spaced apart in the second direction and are located on the side of the photosensitive component facing the installation space. The second direction is perpendicular to the plane where the image sensor is located, and the projection of the first driving mechanism on the plane where the sensor circuit board is located covers part of the sensor circuit board.

[0011] It can be understood that the anti-shake motor in this embodiment is arranged so that the first coil of the first drive mechanism and the photosensitive component are spaced apart in the second direction, and the first drive mechanism can be located on the side of the photosensitive component facing the installation space. At the same time, the projection of the first drive mechanism on the plane where the sensor circuit board is located can cover part of the sensor circuit board. In this way, on the one hand, the first coil and the sensor circuit board are spaced apart in the second direction, so that the length and / or width of the sensor circuit board can be smaller, thereby effectively reducing the length and / or width of the movable base and the fixed bracket, so as to save the length and / or width of the entire anti-shake motor, which is conducive to the miniaturization of the anti-shake motor. On the other hand, the first coil can be located on the side of the photosensitive component facing the installation space, so that the first drive mechanism can also utilize the dimensional space of the optical element in the second direction, which is conducive to the miniaturization of the anti-shake motor.

[0012] In one possible implementation, the photosensitive component further includes an electronic device, which is fixed to the sensor circuit board and spaced apart from the image sensor, and the projection of the first driving mechanism on the plane where the sensor circuit board is located covers at least part of the electronic device.

[0013] It is understood that the projection of the first drive mechanism onto the plane of the sensor circuit board can also cover at least a portion of the electronic components located on the sensor circuit board. This allows the first drive mechanism to utilize the length and / or width of the electronic components, effectively reducing the length and / or width of the sensor circuit board, as well as the length and / or width of the movable base and fixed bracket, thereby reducing the length and / or width of the entire anti-shake motor and facilitating a miniaturized anti-shake motor. Furthermore, compared to anti-shake motors in which the first coil is located on the sensor circuit board and the electronic components are located within the coil hole of the first coil, a portion of the first coil is still present between the electronic components and the image sensor, resulting in a greater distance between the electronic components and the image sensor and a larger overall size of the sensor circuit board, hindering the miniaturization of the anti-shake motor. In this embodiment, the first coil and the photosensitive component are arranged in the second direction, allowing the electronic components to be placed as close to the image sensor as possible, thus reducing the size of the sensor circuit board and, consequently, facilitating a miniaturized anti-shake motor.

[0014] In one possible implementation, the first drive mechanism is spaced apart from the optical element mounted on the fixed bracket in the first direction. In this way, the first drive mechanism can also utilize the space provided by the optical element in the second direction, thereby facilitating a miniaturized anti-shake motor.

[0015] In one possible implementation, the photosensitive component and the first coil are fixed on opposite sides of the movable base. In this way, the photosensitive component can be spaced apart from the first coil in the second direction, which is conducive to miniaturizing the anti-shake motor.

[0016] In one possible implementation, the movable base has a receiving space for accommodating a portion of the fixed bracket and at least a portion of the optical element mounted on the fixed bracket. The movable base includes a base top, a base frame, and a base bottom. The base frame is connected between the base top and base bottom, and the receiving space is located inside the base frame. The first coil is fixed to the base top, the photosensitive component is fixed to the base bottom, and the fixed bracket is movably connected to the base bottom. In this way, the first coil can be spaced apart from the photosensitive component in the second direction, which facilitates the miniaturization of the anti-shake motor.

[0017] In one possible implementation, the base has a first through-hole at the bottom, connecting the receiving space and the mounting space of the fixed bracket. The photosensitive component is fixedly connected to the surface of the base bottom facing away from the base top, with the image sensor facing the first through-hole. In this way, the photosensitive component can be fixed to the surface of the base bottom facing away from the base top, making assembly easier.

[0018] In one possible implementation, the top of the base includes a first branch, a second branch, and a third branch. The first branch and the third branch are spaced apart in a first direction, the second branch is connected between the first and third branches, and the top of the base partially encloses the optical element. This arrangement allows the top of the base to utilize the space provided by the optical element in the second direction, facilitating a thinner design for the anti-shake motor.

[0019] In one possible implementation, the movable base further comprises a first escape space, located between the top and bottom of the base and outside the base frame. A portion of the fixed bracket is located in the first escape space. This allows the anti-shake motor to be larger overall, compared to conventional anti-shake motors in which the entire movable base is located inside the fixed bracket, or vice versa. In this embodiment, a portion of the fixed bracket can be located in the first escape space, making the overall structure of the fixed bracket and movable base more compact and facilitating a miniaturized anti-shake motor.

[0020] In one possible implementation, the base frame includes a first side portion, a second side portion, and a third side portion. The first side portion and the third side portion are spaced apart in a first direction, and the second side portion is located on the same side of the first and third side portions and fixedly connects the first and third side portions. The surface of the first side portion facing away from the second side portion faces a first escape space, the first escape space communicates with the receiving space, and a portion of the fixing bracket is located on the side of the first side portion facing away from the second side portion. This allows the fixing bracket to utilize the thickness of the first side portion of the base frame portion, facilitating a compact design of the anti-shake motor.

[0021] In one possible implementation, the fixed bracket includes a bracket top, a mounting portion, and a bracket bottom. The bracket top and bracket bottom are spaced apart in the second direction. The mounting portion connects the bracket top and bracket bottom. The mounting portion defines a mounting space, with at least a portion of the mounting portion located within the receiving space. The bracket bottom is movably connected to the base bottom via a ball bearing, and a first magnetic member is fixed to the bracket top. This allows the first magnetic member to be spaced apart from the photosensitive component in the second direction, facilitating a compact anti-shake motor.

[0022] In one possible implementation, part of the mounting portion and part of the top of the base are stacked in the second direction. In this way, the top of the base can utilize the space of the mounting portion in the first direction and / or the third direction, which is conducive to miniaturizing the anti-shake motor.

[0023] In a possible implementation, the bottom of the bracket is located between the bottom and top of the base, and the top of the base is located between the bottom and top of the bracket.

[0024] It is understandable that, compared to a typical anti-shake motor in which the movable base and fixed bracket are stacked in the second direction, the overall thickness of the anti-shake motor is relatively thick, which is not conducive to a thinner anti-shake motor. In this embodiment, by arranging the base bottom and base top of the movable base and the bracket bottom and bracket top of the fixed bracket to be alternately stacked in the second direction, the movable base and the fixed bracket can be nested with each other to utilize the space between them in the second direction, thereby making the overall structure of the movable base and the fixed bracket more compact, which helps to reduce the size of the anti-shake motor in the second direction and facilitates the miniaturization of the anti-shake motor.

[0025] In one possible implementation, the top portion of the bracket includes a frame portion and a plate portion. The plate portion is fixedly connected to the surface of the frame portion facing away from the bracket bottom. A portion of the mounting portion is located inside the frame portion. A portion of the frame portion is fixedly connected to the mounting portion, while another portion of the frame portion is spaced apart from the mounting portion to form a gap. A first magnetic member is fixedly connected to the plate portion, with at least a portion of the first magnetic member located within the gap. This allows the first magnetic member to utilize the thickness of the optical element, facilitating a thinner design for the anti-shake motor.

[0026] In one possible implementation, the anti-shake motor further includes a first circuit board, which includes a first fixing portion, a second fixing portion, a third fixing portion, and a first surrounding portion. The first fixing portion is fixedly connected to the top of the base and the first coil, and is electrically connected to the first coil. The second fixing portion is fixedly connected to the bottom of the base and is electrically connected to the sensor circuit board. The third fixing portion is fixedly connected to the surface of the top of the bracket facing away from the bottom of the bracket. One end of the first surrounding portion is fixedly connected to the first fixing portion, and the other end of the first surrounding portion is fixedly connected to the third fixing portion. The first surrounding portion is also fixedly connected to the first fixing portion, and the first surrounding portion is disposed around a portion of the movable base.

[0027] It will be appreciated that, in addition to enabling electrical signal transmission, the first circuit board in this embodiment also provides stiffness values ​​in different directions for the overall movement of the movable base and the photosensitive component. This minimizes the difference in stiffness between the various positions of the entire anti-shake motor, helping to ensure the stability of the image sensor's anti-shake performance in various positions during the movement of the anti-shake motor and improve the anti-shake accuracy of the anti-shake motor. Furthermore, the first circuit board can be bent multiple times to wrap around portions of the movable base, increasing its overall length and reducing its elastic modulus. This helps reduce the driving force required to move the movable base relative to the fixed bracket, thereby lowering the power consumption of the anti-shake motor during optical image stabilization.

[0028] In one possible implementation, the fixed bracket further includes a support portion, the support portion being connected between the top of the bracket and the bottom of the bracket, the support portion being connected to the mounting portion, the support portion having a second through hole, and the second through hole being connected to the mounting space. The first surrounding portion includes a first bending section, a second bending section, and a third bending section connected in sequence, the first bending section being fixedly connected to the first fixing section and the second fixing section, and the third bending section being fixedly connected to the third fixing section. The first bending section is spaced apart from the movable base in a third direction, the second bending section is spaced apart from the movable base in the first direction, the third bending section is located on a side of the movable base facing away from the first bending section, and is fixedly connected to the support portion, the third direction intersecting with the first direction and being perpendicular to the plane where the image sensor is located.

[0029] It is understandable that the first circuit board in this embodiment can be bent multiple times to surround part of the movable base, so that the overall length of the first circuit board is longer, thereby reducing the elastic coefficient of the first circuit board itself, which is beneficial to reducing the driving force required for the movable base to move relative to the fixed bracket, and is beneficial to reducing the power consumption of the anti-shake motor when performing optical image stabilization. Secondly, the first surrounding portion can be arranged to surround part of the movable base, so that the first surrounding portion can also provide stiffness values ​​in different directions for the overall movement of the movable base and the photosensitive component, so that the difference in the entire anti-shake motor in different postures is small, which is beneficial to ensure the stability of the anti-shake performance of the image sensor in different postures during the movement of the anti-shake motor, and improve the anti-shake accuracy of the anti-shake motor. In addition, the support portion can also provide support and fixation for the first circuit board, thereby preventing the first circuit board from interfering with the movable base during its movement.

[0030] In one possible implementation, the anti-shake motor further includes a second circuit board, the second circuit board including a fourth fixing portion, a fifth fixing portion, and a second surrounding portion. The fourth fixing portion is fixedly connected to the bottom of the base and electrically connected to the sensor circuit board, and the fifth fixing portion is fixedly connected to a surface of the top of the bracket facing away from the bottom of the bracket. One end of the second surrounding portion is fixedly connected to the fourth fixing portion, and the other end of the second surrounding portion is fixedly connected to the fifth fixing portion. The second surrounding portion is disposed around a portion of the movable base, with a portion of the second surrounding portion and a portion of the first surrounding portion located on opposite sides of the movable base.

[0031] It will be appreciated that, in addition to enabling electrical signal transmission, the second circuit board in this embodiment also provides stiffness in the first and third directions for the combined movement of the movable base and the photosensitive assembly, thereby improving the motion precision of the movable base and, consequently, the stabilization accuracy of the image stabilization motor. Furthermore, the second circuit board can be bent multiple times to wrap around portions of the movable base, increasing its overall length and reducing its elastic modulus. This helps reduce the driving force required to move the movable base relative to the fixed bracket, thereby lowering the power consumption of the image stabilization motor during optical image stabilization.

[0032] Secondly, in this embodiment, the first surrounding portion of the first circuit board and the second surrounding portion of the second circuit board can be symmetrically structured. The length of the first surrounding portion can be equal to the length of the second surrounding portion. In this way, when the movable base moves relative to the fixed bracket, the first and second circuit boards can generate forces of equal magnitude and opposite directions to offset each other due to the resistance to deformation. This can reduce the impact of the first and second circuit boards on the motion accuracy of the movable base and improve the anti-shake accuracy of the anti-shake motor.

[0033] In one possible implementation, the second wraparound portion includes a fourth bend segment, a fifth bend segment, and a sixth bend segment connected in sequence. The fourth bend segment is fixedly connected to the fourth fixing portion, and the sixth bend segment is fixedly connected to the fifth fixing portion. The fourth bend segment is located on the side of the top of the base facing the first bend segment, the fifth bend segment is located on the side of the movable base facing away from the second bend segment, and the sixth bend segment is located on the side of the movable base facing away from the fourth bend segment. The sixth bend segment is fixedly connected to the support portion, and the second through hole of the support portion is located between the third bend segment and the sixth bend segment.

[0034] It is understood that in this embodiment, the second circuit board can be bent multiple times to wrap around a portion of the movable base, increasing its overall length and reducing its own elastic modulus. This helps reduce the driving force required to move the movable base relative to the fixed bracket, thereby reducing the power consumption of the anti-shake motor during optical image stabilization. Furthermore, the second wraparound portion can wrap around a portion of the movable base, providing different stiffness values ​​for the overall movement of the movable base and the photosensitive component in different directions. This minimizes the difference in the overall stiffness of the anti-shake motor in different postures, helping to ensure the stability of the image sensor's anti-shake performance in different postures during the movement of the anti-shake motor and improving the anti-shake accuracy of the anti-shake motor.

[0035] In a possible implementation, a projection of the fourth bending segment on the plane where the first bending segment is located partially covers the first bending segment, and the fourth bending segment and the first bending segment are spaced apart in the second direction.

[0036] It will be appreciated that in this embodiment, the first bend section of the first circuit board and the fourth bend section of the second circuit board overlap, thereby extending the length of the first and second circuit boards. This helps reduce the spring coefficients of the first and second circuit boards, reduces the driving force required to move the movable base relative to the fixed bracket, and reduces the power consumption of the anti-shake motor when performing optical image stabilization. Furthermore, the first bend section of the first circuit board can directly face a portion of the fourth bend section of the second circuit board while also being spaced apart from the fourth bend section of the second circuit board in the third direction. This effectively prevents collision and interference between the first and second circuit boards, which could affect the normal operation of the anti-shake motor.

[0037] In one possible implementation, the anti-shake motor further includes a first position sensor. The base has a first mounting slot on its top, with its opening facing the first coil. The first position sensor is received in the first mounting slot. This prevents collision between the first magnetic member and the first position sensor, which could lead to device failure, thereby extending the life of the anti-shake motor.

[0038] In one possible implementation, the first drive mechanism further includes a third coil, which is fixed to the top of the base and spaced apart from the first coil in three directions. The third coil is disposed opposite the first magnetic member and cooperates with the first magnetic member to drive the movable base to move relative to the fixed bracket in a first direction, where the third direction intersects the first direction and is perpendicular to the plane of the image sensor. The first and third coils cooperate with the first magnetic member to drive the movable base to move relative to the fixed bracket in the first direction and / or to drive the movable base to rotate relative to the fixed bracket about the light input axis of the image sensor.

[0039] It can be understood that the movable base in this embodiment can drive the image sensor to move relative to the fixed bracket along the first direction to achieve anti-shake of the anti-shake motor in the first direction. On this basis, the anti-shake motor in this embodiment is also provided with a third coil to cooperate with the first magnetic part to generate a second driving force. The magnitude of the second driving force is different from the magnitude of the first driving force generated by the cooperation of the first coil and the first magnetic part. In this way, the movable base can also drive the photosensitive component to rotate relative to the fixed bracket around the first axis under the joint action of the first driving force and the second driving force, thereby compensating for the jitter generated when the electronic device rotates around an axis parallel to the second direction, so that the anti-shake motor can achieve multi-axis anti-shake, and the anti-shake motor can cover more anti-shake scenarios, which is conducive to improving imaging quality and enhancing user experience.

[0040] In one possible implementation, the anti-shake motor further includes a second drive mechanism, comprising a second coil and a second magnetic member. One of the second coil and the second magnetic member is fixed to the fixed bracket, and the other is fixed to the movable base. The second coil and the second magnetic member are disposed opposite each other and cooperate with each other to drive the movable base to move relative to the fixed bracket in a third direction. The third direction intersects with the first direction and is perpendicular to the plane of the image sensor. The second coil and the photosensitive component are spaced apart in the second direction. In this way, the movable base can also drive the image sensor to move relative to the fixed bracket in the third direction to achieve anti-shake of the anti-shake motor in the third direction. This allows the anti-shake motor to achieve multi-axis anti-shake, covering more anti-shake scenarios, and is conducive to improving imaging quality and enhancing the user experience.

[0041] In a possible implementation, the second driving mechanism and the optical element mounted on the fixing bracket are spaced apart in the third direction.

[0042] In this way, by arranging the second driving mechanism and the optical element to be spaced apart in the third direction, the second driving mechanism can also utilize the size space of the optical element in the second direction, which is conducive to achieving a thinner setting of the anti-shake motor.

[0043] In one possible implementation, the second coil is fixed to the side of the movable base facing away from the photosensitive component. This allows the second coil and the photosensitive component to be spaced apart in the second direction, which helps reduce the size of the sensor circuit board and, consequently, the size of the anti-shake motor, facilitating a miniaturized anti-shake motor.

[0044] In a possible implementation, the anti-shake motor further includes a dielectric layer plate, the first coil and the second coil are both embedded in the dielectric layer plate, and the material of the dielectric layer plate is an insulating material.

[0045] It is understood that the anti-shake motor in this embodiment may also include a dielectric layer. Both the first coil and the second coil can be embedded in the dielectric layer, which helps improve the manufacturing accuracy of the first and second coils, ensure the flatness of the first coil surface and the second coil surface, and ensure the thickness consistency of the first and second coils. Furthermore, the first coil, the second coil, and the dielectric layer can be assembled together as a whole on top of the base, which helps improve assembly accuracy.

[0046] In one possible implementation, the anti-shake motor further includes a housing and an elastic member. The fixed bracket is fixedly connected to the housing. The movable base and the photosensitive assembly are both located inside the housing. The housing has a third through-hole that communicates with the mounting space. The elastic member is fixedly connected between the movable base and the housing. In this way, when the movable base drives the photosensitive assembly to move relative to the fixed bracket, the elastic member provides stiffness in the first and third directions for the combined movement of the movable base and the photosensitive assembly, thereby improving the motion accuracy of the movable base and, consequently, the anti-shake accuracy of the anti-shake motor.

[0047] In a second aspect, a camera module is provided, which includes an optical element and the aforementioned anti-shake motor, wherein the optical element is mounted on a fixing bracket of the anti-shake motor.

[0048] It is understood that the anti-shake motor in this embodiment is arranged so that the first coil of the first drive mechanism and the photosensitive component are spaced apart in the second direction, and the first drive mechanism can be located on the side of the photosensitive component facing the installation space. At the same time, the projection of the first drive mechanism on the plane where the sensor circuit board is located can cover part of the sensor circuit board. In this way, on the one hand, the first coil and the sensor circuit board are spaced apart in the second direction, so that the length and / or width of the sensor circuit board can be smaller, thereby effectively reducing the length and / or width of the movable base and the fixed bracket, thereby saving the length and / or width of the entire anti-shake motor, which is conducive to the miniaturization of the anti-shake motor. On the other hand, the first coil can be located on the side of the photosensitive component facing the installation space, so that the first drive mechanism can also utilize the dimensional space of the optical element in the second direction, which is conducive to the miniaturization of the anti-shake motor. When this anti-shake motor is used in a camera module, it is conducive to the miniaturization of the entire camera module.

[0049] In a third aspect, an electronic device is provided, which includes a device housing and the aforementioned camera module, wherein the camera module is disposed in the device housing.

[0050] It will be appreciated that the anti-shake motor in this embodiment, by spacing the first coil of the first drive mechanism from the photosensitive component in the second direction, can be located on the side of the photosensitive component facing the mounting space. Furthermore, the projection of the first drive mechanism onto the plane of the sensor circuit board can partially cover the sensor circuit board. This spacing of the first coil from the sensor circuit board in the second direction allows the sensor circuit board to be smaller in length and / or width, effectively reducing the length and / or width of the movable base and fixed bracket, thereby saving the length and / or width of the entire anti-shake motor and facilitating a compact design. Furthermore, the first coil can be located on the side of the photosensitive component facing the mounting space, allowing the first drive mechanism to utilize the space available for optical components in the second direction, facilitating a compact design of the anti-shake motor. When this anti-shake motor is used in a camera module, it facilitates a compact design of the entire camera module. The camera module in this embodiment is smaller in size, thus conserving internal space within the electronic device.

[0051] In one possible implementation, the anti-shake motor and optical element form a first anti-shake assembly. The camera module also includes a second anti-shake assembly, located on the object side of the first anti-shake assembly. The second anti-shake assembly includes an optical folding element and a drive motor. The drive motor is used to drive the optical folding element, and the optical element is used to reflect light emitted by the optical folding element to the image sensor of the anti-shake motor. In this way, the camera module can be simultaneously anti-shake using the first and second anti-shake assemblies, which helps improve the camera module's anti-shake accuracy, image quality, and user experience.

[0052] In one possible implementation, the camera module further includes a main circuit board, a first driver chip, and a second driver chip. The main circuit board is electrically connected to the anti-shake motor, the drive motor, the first driver chip, and the second driver chip. The first driver chip is used to control the anti-shake motor to drive the optical element, and the second driver chip is used to control the drive motor to drive the optical folding element.

[0053] It is understood that the electronic device in this embodiment utilizes a first driver chip and a second driver chip to control the anti-shake motor to drive the optical element for anti-shake, and the drive motor to drive the optical folding element for anti-shake. Thus, by combining the first and second anti-shake components to achieve optical anti-shake, the camera module's anti-shake angle is improved, providing a better user experience. This helps improve the overall anti-shake accuracy of the camera module and enhances image quality.

[0054] In one possible implementation, the electronic device further includes a gyroscope electrically connected to a first driver chip and a second driver chip. The gyroscope is configured to obtain posture information of the electronic device and split the posture information into first position information and second position information. The first driver chip is configured to control an anti-shake motor based on the first position information to drive the optical element to a first target position. The second driver chip is configured to control a drive motor based on the second position information to drive the optical folding element to a second target position.

[0055] It can be understood that in this embodiment, a gyroscope is set to obtain the posture information of the electronic device and split it into first position information and second position information. The first driver chip and the second driver chip respectively drive the corresponding motors for anti-shake according to the first position information and the second position information, so that the camera module can fully utilize the anti-shake performance of the two anti-shake components, improve the anti-shake efficiency, and enhance the user experience.

[0056] In one possible implementation, the electronic device further includes a gyroscope electrically connected to a first driver chip and a second driver chip. The gyroscope is configured to obtain posture information of the electronic device and transmit the posture information to the first driver chip. The first driver chip is configured to split the posture information into first position information and second position information. The first driver chip is further configured to control an anti-shake motor to drive the optical element to a first target position based on the first position information. The first driver chip is further configured to transmit the second position information to a second driver chip. The second driver chip is configured to control a drive motor to drive the optical folding element to a second target position based on the second position information.

[0057] It can be understood that in this embodiment, a gyroscope is set to obtain the posture information of the electronic device and split it into first position information and second position information. The first driver chip and the second driver chip respectively drive the corresponding motors for anti-shake according to the first position information and the second position information, so that the camera module can fully utilize the anti-shake performance of the two anti-shake components, improve the anti-shake efficiency, and enhance the user experience.

[0100] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0101] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

[0102] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0103] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0104] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in another embodiment" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0105] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0106] Fig. 1 is a schematic diagram of the structure of an electronic device 1000 provided in some embodiments of the present application. Fig. 2 is a schematic diagram of the cross-sectional structure of the electronic device 1000 shown in Fig. 1 taken along line AA in one embodiment.

[0107] As shown in Figures 1 and 2, electronic device 1000 can be a device with a camera module, 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 of the embodiment shown in Figure 1 is described using a mobile phone as an example.

[0108] As shown in Figures 1 and 2, 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 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0109] For ease of description, the length direction of the electronic device 1000 is defined as the X-axis, which is the first direction X. The thickness direction of the electronic device 1000 is defined as the Z-axis, which is the second direction Z. The width direction of the electronic device 1000 is defined as the Y-axis, which is the third direction Y. It is understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.

[0110] In this embodiment, the device housing 200 may include a frame 2001 and a back cover 2002. The back cover 2002 is fixed to the frame 2001. For example, the back cover 2002 may be fixed to the frame 2001 by adhesive. The back cover 2002 may also be integrally formed with the frame 2001, that is, the back cover 2002 and the frame 2001 form a single unitary structure.

[0111] Alternatively, the screen 300 can be located on the side of the frame 2001 away from the back cover 2002. In this case, the screen 300 and the back cover 2002 are located on either side of the frame 2001. The screen 300, the frame 2001, and the back cover 2002 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 either flat or curved.

[0112] For example, the camera module 100 can be a periscope camera module. The camera module 100 can be located inside the electronic device 1000. The camera module 100 can be fixed to the side of the screen 300 facing the back cover 2002. The back cover 2002 can be provided with a light-transmitting hole 2003. The shape of the light-transmitting hole 2003 is not limited to the circular shape shown in FIG. 1. The light-transmitting hole 2003 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 2003. The camera module 100 can collect ambient light entering the interior of the electronic device 1000.

[0113] Fig. 3 is a schematic diagram of the structure of the first anti-shake component 10 of the camera module 100 shown in Fig. 2 in some embodiments. Fig. 4 is a schematic diagram of the exploded structure of the first anti-shake component 10 shown in Fig. 3 in some embodiments.

[0114] As shown in Figures 2 to 4, the camera module 100 may include an optical folding element 30b, a focusing assembly 20, and a first anti-shake assembly 10, which are sequentially arranged along the optical axis. In this embodiment, the optical folding element 30b, the focusing assembly 20, and the first anti-shake assembly 10 may be sequentially arranged in the third direction Y. Exemplarily, the optical folding element 30b may be a reflecting prism or a reflecting plane mirror. Light from the outside of the electronic device 1000 may enter the interior of the electronic device 1000 through the light-transmitting hole 2003, and then pass through the optical folding element 30b, the focusing assembly 20, and the first anti-shake assembly 10 in sequence. Among them, the optical folding element 30b can be used to reflect the light entering the interior of the electronic device 1000 to the focusing assembly 20.

[0115] Exemplarily, the first anti-shake component 10 may include an anti-shake motor 10a and an optical element 10b. The optical element 10b may be mounted on the anti-shake motor 10a. The optical element 10b may be a reflective prism. The anti-shake motor 10a may include a photosensitive component 1. After the light is emitted by the focusing component 20, it may be reflected by the optical element 10b and finally enter the photosensitive component 1. At this time, the anti-shake motor 10a may realize optical image stabilization (OIS) of the camera module 100 by driving the photosensitive component 1 to move relative to the optical element 10b along the first direction X and / or the third direction Y, thereby improving the imaging quality of the camera module 100.

[0116] For example, the focusing assembly 20 may include a lens group 20a and a focus motor 20b. The lens group 20a may be mounted on the focus motor 20b. The focus motor 20b may drive the lens group 20a to move along the optical axis (i.e., the third direction Y in this embodiment) to achieve auto focus (AF). The lens group 20a may include at least one lens. The optical folding element 30b, the optical element 10b, and the lens group 20a may together constitute the optical system of the camera module 100.

[0117] Figure 5 is a schematic cross-sectional view of the first anti-shake assembly shown in Figure 3 taken along line BB in one embodiment. Figure 6 is a schematic exploded view of the anti-shake motor 10a shown in Figure 3 in some embodiments.

[0118] As shown in Figures 4 to 6, the anti-shake motor 10a may further include a fixed bracket 2, a movable base 3, a first drive mechanism 4, and a second drive mechanism 5. The fixed bracket 2 may have a mounting space 2a for mounting the optical element 10b. The movable base 3 may be movably connected to the fixed bracket 2. The first drive mechanism 4 may be used to drive the movable base 3 to move relative to the fixed bracket 2 in a first direction X. The second drive mechanism 5 may be used to drive the movable base 3 to move relative to the fixed bracket 2 in a third direction Y. The first drive mechanism 4 may include a first coil 41 and a first magnetic member 42. The first coil 41 may be mounted on the movable base 3. The first magnetic member 42 may be mounted on the fixed bracket 2. The first coil 41 may be spaced apart from the photosensitive component 1 in the second direction Z. The projection of the first drive mechanism 4 on the plane of the sensor circuit board 12 may cover at least a portion of the electronic device 13. A portion of the second drive mechanism 5 may be mounted on the movable base 3, while another portion may be mounted on the fixed bracket 2.

[0119] Exemplarily, the photosensitive component 1 can be fixed to the movable base 3. The photosensitive component 1 may include an image sensor 11, a sensor circuit board 12 and an electronic device 13. The image sensor 11 can be fixed to the sensor circuit board 12 and electrically connected to the sensor circuit board 12. The image sensor 11 can face the installation space 2a of the fixed bracket 2. The electronic device 13 can be fixed to the sensor circuit board 12 and electrically connected to the sensor circuit board 12. The electronic device 13 can be spaced apart from the image sensor 11 in the first direction X. Exemplarily, the electronic device 13 may include one or more capacitors and / or inductors and other electronic components that can be used to assist the image sensor 11 in processing image signals (for example, for filtering, etc.).

[0120] When the optical element is installed in the installation space 2a, the first driving mechanism 4 and / or the second driving mechanism 5 can drive the movable base 3 to drive the photosensitive component 1 to move along the first direction X and / or the third direction Y relative to the fixed bracket 2, that is, to move along the first direction X and / or the third direction Y relative to the optical element to achieve optical image stabilization.

[0121] It can be understood that, compared to the first coil of the first drive mechanism being fixed to the sensor circuit board, the first coil and the image sensor are arranged in the first direction X. This results in a larger sensor circuit board and the entire anti-shake motor in the first direction X, hindering the miniaturization of the anti-shake motor. In this embodiment, the anti-shake motor 10a is designed by arranging the first coil 41 of the first drive mechanism 4 in the second direction Z, spaced apart from the photosensitive component 1. The projection of the first drive mechanism 4 onto the plane of the sensor circuit board 12 can cover at least a portion of the electronic components 13 of the photosensitive component 1. Thus, the first coil 41 is spaced apart from the sensor circuit board 12 in the second direction Z, and the projection of the first coil 41 onto the plane of the sensor circuit board 12 can cover at least a portion of the electronic components 13, effectively reducing the size of the sensor circuit board 12 in the first direction X and the overall size of the anti-shake motor 10a in the first direction X. In other words, the anti-shake motor 10a in this embodiment can achieve optical image stabilization while simultaneously miniaturizing the anti-shake motor 10a.

[0122] In other embodiments, the positions of the first coil 41 and the first magnetic member 42 may be interchanged, that is, the first coil 41 may be fixed to the fixed bracket 2 , and the first magnetic member 42 may be fixed to the movable base 3 .

[0123] The specific structure of the anti-shake motor 10 a will be described below with reference to the relevant drawings.

[0124] Fig. 7 is a schematic diagram of the structure of the movable base 3 shown in Fig. 6 in some embodiments. Fig. 8 is a schematic diagram of the structure of the movable base 3 shown in Fig. 6 from another perspective.

[0125] As shown in Figures 6 to 8, the movable base 3 may include a base top 31, a base frame portion 32 and a base bottom 33. The base top 31 and the base bottom 33 may be located on opposite sides of the base frame portion 32, and fixedly connected to the base frame portion 32. Among them, the movable base 3 may have a receiving space 3a. The receiving space 3a may be located on the inner side of the base frame portion 32. The base bottom 33 may be provided with a first through hole 331. The first through hole 331 may be connected to the receiving space 3a of the movable base 3. The receiving space 3a may be used to accommodate part of the fixed bracket 2 and the optical element 10b at least partially mounted on the fixed bracket 2 (please refer to Figure 5).

[0126] For example, the base frame portion 32 may include a first side portion 321, a second side portion 322, and a third side portion 323 connected in sequence. The first side portion 321 and the third side portion 323 may be located on the same side of the second side portion 322. The first side portion 321, the second side portion 322, and the third side portion 323 may collectively enclose an inner side of the base frame portion 32. The surface of the first side portion 321 facing away from the second side portion 322 is a first surface 3211. The surface of the first side portion 321 facing away from the third side portion 323 is a second surface 3212. The surface of the third side portion 323 facing away from the second side portion 322 is a third surface 3231. The surface of the third side portion 323 facing away from the first side portion 321 is a fourth surface 3232.

[0127] Exemplarily, the base top 31 may include a first branch 311, a second branch 312, and a third branch 313. The second branch 312 may be connected between the first branch 311 and the third branch 313. The first branch 311, the second branch 312, and the third branch 313 may surround the receiving space 3a of the movable base 3. That is, the base top 31 of the movable base 3 may semi-enclose the receiving space 3a. The first branch 311 may be opposite to and spaced apart from a portion of the base bottom 33. The third branch 313 may be opposite to and spaced apart from a portion of the base bottom 33. It should be understood that the first branch 311, the second branch 312, and the third branch 313 are schematically demarcated by dotted lines in both Figures 7 and 8.

[0128] For example, the movable base 3 may further include a first escape space 3b. The first escape space 3b may be located between the first branch 311 and the base bottom 33, and outside the base frame 32. The first surface 3211 and the second surface 3212 of the first side portion 321 may both face the first escape space 3b. The first escape space 3b may communicate with the receiving space 3a of the movable base 3.

[0129] For example, the movable base 3 may further include a second escape space 3c. The second escape space 3c may be located between the third branch 313 and the base bottom 33, and outside the base frame 32. The third surface 3231 and the fourth surface 3232 of the third side portion 323 may both face the second escape space 3c. The second escape space 3c may communicate with the receiving space 3a of the movable base 3.

[0130] For example, the base bottom 33 is provided with multiple movable grooves, including, for example, a first movable groove 332, a second movable groove 333, a third movable groove 334, and a fourth movable groove 335. The four movable grooves may be located at the four corners of the movable base 3, respectively. The openings of the four movable grooves may all face the base top 31. The first movable groove 332 and the second movable groove 333 may communicate with the first escape space 3b. The third movable groove 334 and the fourth movable groove 335 may communicate with the second escape space 3c.

[0131] In some embodiments, the base frame portion 32 may include an inner frame portion and an outer frame portion. The inner frame portion may be fixed to the inner side of the outer frame portion. The inner frame portion may be fixedly connected to the top of the base 31, and together with the top of the base 31, constitute a first base. The outer frame portion may be fixedly connected to the bottom of the base 33, and together with the bottom of the base 33, constitute a second base. In this way, compared to the movable base being an integrally formed structure, the movable base has more structural features and is more difficult to prepare. The movable base 3 in this embodiment can be decoupled into a first base and a second base, and the first base and the second base can be prepared separately and then assembled, which is conducive to reducing the difficulty of preparing the movable base 3 and improving the preparation accuracy of the movable base 3.

[0132] FIG9 is a schematic structural diagram of the first circuit board 61 shown in FIG6 from another perspective.

[0133] As shown in Figure 9, the anti-shake motor 10a may further include a first circuit board 61. The first circuit board 61 may be a flexible circuit board or a rigid-flexible circuit board. The first circuit board 61 may include a first fixing portion 611, a second fixing portion 612, a third fixing portion 613, and a first surrounding portion 614. The second fixing portion 612 and the third fixing portion 613 may be located on opposite sides of the first fixing portion 611, and each may be spaced apart from the first fixing portion 611. One end of the first surrounding portion 614 may be fixedly connected to the first fixing portion 611 and the second fixing portion 612. The other end of the first surrounding portion 614 may be fixedly connected to the third fixing portion 613. The first surrounding portion 614 may be bent relative to the first fixing portion 611 and the second fixing portion 612. The first surrounding portion 614 may also be bent relative to the third fixing portion 613. The first surrounding portion 614 may surround a portion of the first fixing portion 611. It should be noted that although the first circuit board 61 is described as being divided into multiple parts in this embodiment, this does not affect the fact that the first circuit board 61 is a one-piece structure.

[0134] Exemplarily, the first surrounding portion 614 may include a first bending section 614a, a second bending section 614b, and a third bending section 614c connected in sequence. The end of the first bending section 614a facing away from the second bending section 614b may be fixedly connected to the first fixing portion 611 and the second fixing portion 612. The first bending section 614a may be bent relative to the first fixing portion 611 and the second fixing portion 612 (for example, the plane on which the first bending section 614a lies may be arranged at an angle to the plane on which the first fixing portion 611 lies). The first bending section 614a may be located on the same side of the first fixing portion 611 and the second fixing portion 612. The second bending section 614b may be bent relative to the first bending section 614a. The second bending section 614b may be spaced apart from the first fixing portion 611 in the first direction X. The third bending section 614c may be bent relative to the second bending section 614b. The third bending section 614c may be fixedly connected to the third fixing portion 613. The third bent section 614c can be spaced apart from the first bent section 614a in the third direction Y. The third bent section 614c can face the first bent section 614a. A portion of the first fixing portion 611 can be located between the first bent section 614a and the third bent section 614c. The third bent section 614c can be located on a side of the third fixing portion 613 facing the first fixing portion 611 and bent relative to the third fixing portion 613.

[0135] Fig. 10 is a schematic diagram of the assembled structure of the movable base 3 and the first circuit board 61 shown in Fig. 6. Fig. 11 is a schematic diagram of the structure shown in Fig. 10 from another perspective.

[0136] As shown in Figures 10 and 11, the first fixing portion 611 can be located on the surface of the base top 31 of the movable base 3 facing away from the base bottom 33, and fixedly connected to the base top 31. The shape of the first fixing portion 611 can be adapted to the shape of the base top 31. Exemplarily, the first fixing portion 611 can also include three branches connected in sequence. The three branches of the first fixing portion 611 can be respectively connected to the three branches of the base top 31 (i.e., the first branch 311, the second branch 312, and the third branch 313 in this embodiment). The second fixing portion 612 can be fixedly connected to the surface of the base bottom 33 facing away from the base top 31. The second fixing portion 612 can be roughly "L"-shaped. The second fixing portion 612 can be located on the circumferential side of the first through hole 331. The third fixing portion 613 can be located on the side of the base top 31 facing away from the base bottom 33.

[0137] For example, the first surrounding portion 614 may be disposed around a portion of the base top 31 of the movable base 3. The first bent section 614a may be located on the side of the second branch 312 of the base top 31 facing away from the receiving space 3a. The first bent section 614a may be spaced apart from the base frame 32 in the third direction Y. The second bent section 614b may be located on the side of the third side 323 of the base frame 32 facing away from the first side 321. In other words, the second bent section 614b may be located on the side of the third branch 313 of the base top 31 facing away from the first branch 311. The second bent section 614b may be spaced apart from the base frame 32 in the first direction X. The third bent section 614c may be located on the side of the base frame 32 facing away from the first bent section 614a. In other words, the third bent section 614c may be located on the side of the first branch 311 of the base top 31 facing away from the third branch 313. The third bent section 614 c may be spaced apart from the base frame portion 32 in the third direction Y.

[0138] For example, the base bottom 33 may further include a first groove 336. The opening of the first groove 336 may face away from the first through-hole 331. The connecting portion between the first bent section 614a of the first surrounding portion 614 and the first fixing portion 611 may be received in the first groove 336. Thus, on the one hand, the first groove 336 can be used to position the first bent section 614a during assembly of the first circuit board 61, facilitating assembly. On the other hand, the first surrounding portion 614 of the first circuit board 61 can utilize the dimensional space of the movable base 3 in the third direction Y, making the overall structure of the movable base 3 and the first circuit board 61 more compact, thereby facilitating the miniaturization of the anti-shake motor 10a.

[0139] FIG. 12 is a schematic structural diagram of the second circuit board 62 shown in FIG. 6 in some embodiments.

[0140] As shown in Figure 12, the anti-shake motor 10a may also include a second circuit board 62. The second circuit board 62 may be a flexible circuit board or a soft-hard combination circuit board. The second circuit board 62 may include a fourth fixing portion 621, a fifth fixing portion 622 and a second surrounding portion 623. One end of the second surrounding portion 623 may be connected to the fourth fixing portion 621. The other end of the second surrounding portion 623 may be connected to the fifth fixing portion 622. The second surrounding portion 623 may be bent relative to the fourth fixing portion 621 and the fifth fixing portion 622. It should be noted that although the second circuit board 62 is described as a plurality of parts in this embodiment, it does not affect the second circuit board 62 being an integrally formed structure.

[0141] For example, the second wrapping portion 623 may include a fourth bent section 623a, a fifth bent section 623b, and a sixth bent section 623c, connected in sequence. The end of the fourth bent section 623a facing away from the fifth bent section 623b may be connected to the fourth fixing portion 621. The fourth bent section 623a may be bent relative to the fourth fixing portion 621. The fourth bent section 623a may be located on the same side of the fourth fixing portion 621 and the fifth fixing portion 622. The fifth bent section 623b may be bent relative to the fourth bent section 623a. The sixth bent section 623c may be bent relative to the fifth bent section 623b. The end of the sixth bent section 623c facing away from the fifth bent section 623b may be connected to the fifth fixing portion 622. The sixth bent section 623c may be bent relative to the fifth fixing portion 622. The sixth bent section 623c may be spaced apart from the fourth bent section 623a in the third direction Y. The sixth bending segment 623c may face the fourth bending segment 623a.

[0142] Figure 13 is a schematic diagram of the assembled structure of the first circuit board 61, the second circuit board 62, and the movable base 3 shown in Figure 6. Figure 14 is a schematic diagram of a partial cross-section of the anti-shake motor 10a shown in Figure 4 taken along line CC in one embodiment. Figure 15 is a schematic diagram of the structure shown in Figure 13 from another perspective.

[0143] As shown in Figures 13 to 15, the fourth fixing portion 621 can be fixedly connected to the surface of the base bottom 33 facing away from the base top 31. The fourth fixing portion 621 can be roughly "L"-shaped. The fourth fixing portion 621 can be located around the first through hole 331. The fourth fixing portion 621 can be arranged side by side with the second fixing portion 612 of the first circuit board 61 in the first direction X. The fourth fixing portion 621 and the second fixing portion 612 can have a bilaterally symmetrical structure. The fifth fixing portion 622 can be located on the side of the base top 31 facing away from the base bottom 33. The fifth fixing portion 622 can be arranged side by side with the third fixing portion 613 of the first circuit board 61 in the first direction X. The fifth fixing portion 622 and the third fixing portion 613 can have a bilaterally symmetrical structure.

[0144] For example, the second surrounding portion 623 can be arranged to surround a portion of the movable base 3. The fourth bend section 623a of the second surrounding portion 623 can be spaced apart from the base top 31 of the movable base 3 in the third direction Y. The fifth bend section 623b of the second surrounding portion 623 can be spaced apart from the base top 31 of the movable base 3 in the first direction X. The fifth bend section 623b of the second surrounding portion 623 can be located on the side of the first branch 311 of the base top 31 facing away from the third branch 313. The sixth bend section 623c of the second surrounding portion 623 can be located on the side of the movable base 3 facing away from the fourth bend section 623a of the second surrounding portion 623. The second surrounding portion 623 can be arranged side by side with the first surrounding portion 614 of the first circuit board 61 in the first direction X. The second surrounding portion 623 and the first surrounding portion 614 can have a bilaterally symmetrical structure.

[0145] For example, the projection of the second fixing portion 612 of the first circuit board 61 onto the plane of the base top 31 can partially cover the first branch 311 of the base top 31. The projection of the third fixing portion 613 of the first circuit board 61 onto the plane of the base top 31 can partially cover the third branch 313 of the base top 31. This allows the distance between the second fixing portion 612 and the third fixing portion 613 of the first circuit board 61 to be greater, effectively extending the length of the first surrounding portion 614 connected between the second fixing portion 612 and the third fixing portion 613, thereby increasing the overall length of the first circuit board 61 and facilitating a reduction in the elastic modulus of the first circuit board 61.

[0146] For example, the projection of the fourth fixing portion 621 of the second circuit board 62 onto the plane of the base top 31 can partially cover the third branch 313 of the base top 31. The projection of the fifth fixing portion 622 of the second circuit board 62 onto the plane of the base top 31 can partially cover the first branch 311 of the base top 31. Thus, the distance between the fourth fixing portion 621 and the fifth fixing portion 622 of the second circuit board 62 is relatively large, effectively extending the length of the second surrounding portion 623 connected between the fourth fixing portion 621 and the fifth fixing portion 622, thereby increasing the overall length of the second circuit board 62 and facilitating a reduction in the elastic modulus of the second circuit board 62.

[0147] For example, the second fixing portion 612, the third fixing portion 613, and the first surrounding portion 614 of the first circuit board 61 can be substantially bilaterally symmetrical with the fourth fixing portion 621, the fifth fixing portion 622, and the second surrounding portion 623 of the second circuit board 62. The length of the first surrounding portion 614 can be equal to the length of the second surrounding portion 623. The lengths of the first surrounding portion 614 and the second surrounding portion 623 can be completely equal or approximately equal. For example, the difference between the length of the second surrounding portion 623 and the length of the first surrounding portion 614 can be less than or equal to 0.01 times the length of the first surrounding portion 614.

[0148] For example, the first bend section 614a of a portion of the first circuit board 61 can directly face the fourth bend section 623a of the second circuit board 62. In other words, the projection of the first bend section 614a of the first circuit board 61 onto the plane containing the fourth bend section 623a can overlap a portion of the fourth bend section 623a of the second circuit board 62. This allows the first bend section 614a and the fourth bend section 623a to overlap, thereby extending the length of the first and second circuit boards 61, 62. This helps reduce the elastic moduli of the first and second circuit boards 61, 62, and the driving force required to move the movable base 3 relative to the fixed bracket 2, thereby reducing the power consumption of the anti-shake motor 10a during optical image stabilization.

[0149] Please refer to Figures 13 to 15 again. The bottom 33 of the base can also be provided with a second groove 337 (Figure 11 also illustrates the second groove 337 from another angle). The opening of the second groove 337 can face away from the first through hole 331. The second groove 337 can be spaced apart from the first groove 336. The connecting portion of the fourth bending section 623a of the second surrounding portion 623 and the fourth fixing portion 621 can be accommodated in the second groove 337. In this way, on the one hand, the second groove 337 can be used to position the fourth bending section 623a of the second surrounding portion 623 when assembling the second circuit board 62, so as to facilitate assembly; on the other hand, the second surrounding portion 623 of the second circuit board 62 can utilize the dimensional space of the movable base 3 in the third direction Y, so that the overall structure of the movable base 3 and the second circuit board 62 is relatively compact, which is conducive to achieving a miniaturized setting.

[0150] For example, the dimension of the first groove 336 in the third direction Y can be smaller than the dimension of the second groove 337 in the third direction Y. When the first circuit board 61 and the second circuit board 62 are assembled on the movable base 3, the first bend section 614a of the first circuit board 61 can be positioned closer to the base top 31 and the base frame 32 relative to the fourth bend section 623a of the second circuit board 62. In this way, the first bend section 614a of the first circuit board 61 can directly face a portion of the fourth bend section 623a of the second circuit board 62 while also being spaced apart from the fourth bend section 623a of the second circuit board 62 in the third direction Y. This effectively prevents collision and interference between the first and second circuit boards, which could affect the normal operation of the anti-shake motor 10a.

[0151] Figure 16 is a schematic diagram of the partial assembly of the anti-shake motor 10a shown in Figure 6. Figure 17 is a schematic diagram of the structure shown in Figure 16 from another perspective. Figure 18 is a schematic diagram of a partial cross-section of the anti-shake motor 10a shown in Figure 4, taken along line DD. For ease of understanding, the first circuit board 61, second circuit board 62, and dielectric layer 63 of the anti-shake motor 10a are hidden in Figure 17.

[0152] As shown in Figures 16 to 18, the first drive mechanism 4 (see Figure 6) can have two first coils 41. The two first coils 41 can be identical in shape and size. Both first coils 41 can be located on the side of the first fixing portion 611 of the first circuit board 61 facing away from the base top 31 and fixedly connected to the first fixing portion 611. Both first coils 41 can be electrically connected to the first fixing portion 611. One of the first coils 41 can be fixedly connected to the portion of the first fixing portion 611 facing the first branch 311 of the base top 31. The other first coil 41 can be fixedly connected to the portion of the first fixing portion 611 facing the third branch 313 of the base top 31. The two first coils 41 can be connected in series. The arrangement direction of the two first coils 41 can be parallel to the first direction X. The arrangement direction of the two first coils 41 can be the direction of the line connecting the geometric centers of the two first coils 41. For example, the winding plane of the first coils 41 can be parallel to the plane containing the first direction X and the third direction Y.

[0153] For example, the second driving mechanism 5 (see FIG6 ) may include a second coil 51. The number of the second coil 51 may be one. The second coil 51 may be located on the side of the first fixing portion 611 facing away from the base top 31 and fixedly connected to the portion of the first fixing portion 611 facing the second branch 312 of the base top 31. The second coil 51 may be electrically connected to the first fixing portion 611. For example, the winding plane of the second coil 51 may be parallel to the plane in which the first direction X and the third direction Y are located.

[0154] For example, the anti-shake motor 10a may further include a dielectric layer 63. The dielectric layer 63 may be made of an insulating material such as resin or polymer. The first coil 41 and the second coil 51 may both be embedded in the dielectric layer 63. The dielectric layer 63 may be fixed to the surface of the first fixing portion 611 facing away from the base top 31. The shape of the dielectric layer 63 may be substantially the same as that of the first fixing portion 611. The first coil 41, the second coil 51, and the dielectric layer 63 may be integrally formed. For example, the insulating plate with the embedded metal portion may be etched into a coil by etching or other methods. Thus, patterning the first coil 41 and the second coil 51 on the insulating plate with the metal portion by etching or other methods may improve the fabrication accuracy of the first coil 41 and the second coil 51, ensure the surface flatness of the first coil 41 and the second coil 51, and ensure the thickness consistency of the first coil 41 and the second coil 51. At the same time, the first coil 41, the second coil 51, and the dielectric layer 63 can be assembled together as a whole on the base top 31, which helps improve assembly accuracy. In other embodiments, the first coil 41 and / or the second coil 51 can also be wound coils, that is, the first coil 41 and / or the second coil 51 can be prepared by winding a wire multiple times.

[0155] For example, the anti-shake motor 10a may further include multiple position sensors, such as a first position sensor 71, a second position sensor 72, and a third position sensor 73. The base top 31 may further include a first mounting slot 314, a second mounting slot 315, and a third mounting slot 316. The first mounting slot 314 may be formed in the first branch 311 of the base top 31. The opening of the first mounting slot 314 may face the first coil 41. The first position sensor 71 may be received in the first mounting slot 314 and fixedly connected to the first fixing portion 611 of the first circuit board 61. The first position sensor 71 may be electrically connected to the first circuit board 61. The second mounting slot 315 may be formed in the second branch 312 of the base top 31. The opening of the second mounting slot 315 may face the second coil 51. The second position sensor 72 may be received in the second mounting slot 315 and fixedly connected to the first fixing portion 611. The second position sensor 72 may be electrically connected to the first circuit board 61. The third mounting slot 316 may be formed in the third branch 313 of the base top 31. The opening of the third mounting groove 316 may face the first coil 41. The third position sensor 73 may be received in the third mounting groove 316 and fixedly connected to the first fixing portion 611. The third position sensor 73 may be electrically connected to the first circuit board 61.

[0156] For example, the anti-shake motor 10a may further include multiple balls 8, for example, four balls 8. Each ball 8 may have the same shape and size. Therefore, each ball 8 may have the same number. The multiple balls 8 may be disposed in a one-to-one correspondence within the multiple movable grooves (i.e., the first movable groove 332, the second movable groove 333, the third movable groove 334, and the fourth movable groove 335) of the movable base 3.

[0157] For example, the first drive mechanism 4 may further include a third coil 43. The third coil 43 may be located on the side of the first fixing portion 611 facing away from the base top 31 and fixedly connected to the first fixing portion 611. The third coil 43 may be electrically connected to the first fixing portion 611. The third coil 43 may be spaced apart from the first coil 41 in the third direction Y. There may be two third coils 43. The two third coils 43 may have identical shapes and sizes. The third coils 43 may also have identical shapes and sizes to the first coil 41. One of the third coils 43 may be fixedly connected to the portion of the first fixing portion 611 facing the first branch 311 of the base top 31 and spaced apart from one of the first coils 41 in the third direction Y. The other third coil 43 may be fixedly connected to the portion of the first fixing portion 611 facing the third branch 313 of the base top 31 and spaced apart from the other first coil 41 in the third direction Y. The two third coils 43 may be connected in series. The arrangement direction of the two third coils 43 may be parallel to the first direction X. The distance between the two third coils 43 can be equal to the distance between the two first coils 41. For example, the first position sensor 71 can be positioned directly opposite the first coil 41. The third position sensor 73 can be positioned directly opposite the third coil 43. This allows for a larger distance between the first and third position sensors 71, 73, allowing them to detect a wider range of magnetic fields, thereby improving the motion accuracy of the anti-shake motor 10a.

[0158] In other embodiments, the first driving mechanism 4 may not include the third coil 43 .

[0159] Figure 19 is a schematic diagram of the exploded structure of the photosensitive assembly 1 and elastic member 9 shown in Figure 6 in some embodiments. Figure 20 is a schematic diagram of the partial assembly structure of the anti-shake motor 10a shown in Figure 6. Figure 21 is a schematic diagram of the partial cross-section structure of the anti-shake motor 10a shown in Figure 4 taken along line CC in one embodiment.

[0160] As shown in Figures 19 to 21, the sensor circuit board 12 of the photosensitive component 1 can be provided with an avoidance hole 121. Multiple electronic devices 13 can be located around the avoidance hole 121. The photosensitive component 1 can also include a fixing member 14. The fixing member 14 can be fixed to the surface of the sensor circuit board 12 facing away from the electronic devices 13. Part of the fixing member 14 can be exposed through the avoidance hole 121. The image sensor 11 can be fixed to the portion of the fixing member 14 exposed relative to the avoidance hole 121. In this case, the image sensor 11 can be fixed to the sensor circuit board 12 by the fixing member 14. At least part of the image sensor 11 can be located within the avoidance hole 121 of the sensor circuit board 12. The image sensor 11 can be electrically connected to the sensor circuit board 12. In some embodiments, the photosensitive component 1 may not include the fixing member 14. The sensor circuit board 12 may not include the avoidance hole 121. In this case, the image sensor 11 can also be fixedly connected to the surface of the sensor circuit board 12 facing the electronic devices 13. Multiple electronic devices 13 can be located around the image sensor 11 and spaced apart from the image sensor 11. In some embodiments, the fixing member 14 may also be a circuit board, and the image sensor 11 may be fixed to the fixing member 14 by means of a chip-on-board (COP) package or the like. The fixing member 14 may be fixed to the sensor circuit board 12 by means of laser welding or the like. In this way, the image sensor 11 may be electrically connected to the sensor circuit board 12 via the fixing member 14.

[0161] Exemplarily, the photosensitive component 1 may further include a filter 15. The filter 15 may include a filter 151 and a carrier 152. The carrier 152 may be provided with a light hole 1521. The filter 151 may be fixed to the carrier 152. Part of the filter 151 may be exposed relative to the light hole 1521 of the carrier 152. The carrier 152 may be fixed to the surface of the sensor circuit board 12 facing the electronic device 13, and be arranged opposite to the avoidance hole 121 of the sensor circuit board 12. The carrier 152 may be spaced apart from a plurality of electronic devices 13. At this time, the filter 151 may be opposite to and spaced apart from the image sensor 11.

[0162] For example, the periphery of the sensor circuit board 12 may be provided with a plurality of first pins 122. The second fixing portion 612 of the first circuit board 61 may be provided with a plurality of second pins 6121 (see FIG15 ). The fourth fixing portion 621 of the second circuit board 62 may be provided with a plurality of third pins 6211 (see FIG15 ). The plurality of first pins 122 may be fixedly connected to the plurality of second pins 6121 and the plurality of third pins 6211 in a one-to-one correspondence via welding. In other words, the sensor circuit board 12 may be fixedly connected to the first circuit board 61 and the second circuit board 62 via a plurality of solder joints 16, thereby being fixed to the base bottom 33 of the movable base 3. In this case, the optical filter 151 may be positioned opposite the first through hole 331 of the base bottom 33. The image sensor 11 may be positioned directly opposite the first through hole 331. In some embodiments, a portion of the optical filter 15 may also be positioned within the first through hole 331. In some embodiments, the sensor circuit board 12 may also be fixedly connected to the base bottom 33 by bonding or other means.

[0163] For example, the base bottom 33 may further include an escape groove 338 ( FIG. 15 also illustrates the escape groove 338 from another perspective). The escape groove 338 may communicate with the first through-hole 331. When the sensor circuit board 12 is secured to the base bottom 33, the electronic components 13 on the sensor circuit board 12 may be accommodated in the escape groove 338 of the base bottom 33.

[0164] FIG22 is a schematic structural diagram of the structure shown in FIG20 from another perspective.

[0165] As shown in Figures 19, 21, and 22, the anti-shake motor 10a may further include an elastic member 9. The elastic member 9 may be a leaf spring. The elastic member 9 may include a first connecting portion 91, an elastic portion 92, and a second connecting portion 93. The elastic portion 92 may connect the first connecting portion 91 and the second connecting portion 93. The first connecting portion 91 may be fixedly connected to the photosensitive assembly 1. The second connecting portion 93 and the elastic portion 92 may both be spaced apart from the movable base 3.

[0166] For example, the first connecting portion 91 can be connected between the sensor circuit board 12 of the photosensitive component 1 and the fixing member 14. In this way, the connection reliability between the elastic member 9 and the photosensitive component 1 is higher. In some embodiments, the first connecting portion 91 can also be fixedly connected to the surface of the fixing member 14 facing away from the sensor circuit board 12.

[0167] Figure 23 is a schematic diagram of the structure of the fixing bracket 2 of the anti-shake motor 10a shown in Figure 6 in some embodiments. Figure 24 is a schematic diagram of the structure of the fixing bracket 2 shown in Figure 23 from another perspective. Figure 25 is a schematic diagram of the exploded structure of the fixing bracket 2 shown in Figure 23.

[0168] As shown in Figures 23 to 25, the fixed bracket 2 may include a bracket top 21, a mounting portion 22, a bracket bottom 23, and a support portion 24. The bracket top 21 and the bracket bottom 23 may be spaced apart in the second direction Z. The support portion 24 may be connected between the bracket top 21 and the bracket bottom 23. The mounting portion 22 may connect the bracket top 21, the bracket bottom 23, and the support portion 24. The support portion 24 may be provided with a second through hole 241. The mounting portion 22 may have an installation space 2a for mounting an optical element. One opening of the installation space 2a may face the support portion 24 and connect to the second through hole 241. The other opening of the installation space 2a may face away from the bracket top 21 and connect to the external space of the fixed bracket 2. A third avoidance space 2b may be formed between the bracket top 21 and the bracket bottom 23. It should be understood that Figures 23 and 25, as well as subsequent figures, schematically demarcate the bracket top 21, the mounting portion 22, and the support portion 24 with dotted lines.

[0169] Exemplarily, the bracket top 21 may include a frame portion 211 and a plate portion 212. The plate portion 212 may be fixedly connected to the surface of the frame portion 211 facing away from the bracket bottom 23. Part of the mounting portion 22 may be located inside the frame portion 211 and connected to a portion of the frame portion 211. The mounting portion 22 may be spaced apart from another portion of the frame portion 211 to form a gap 213. The frame portion 211 may include a first side portion 2111, a second side portion 2112, a third side portion 2113, and a fourth side portion 2114, which are connected end to end in sequence. The first side portion 2111 may be connected to the support portion 24. The mounting portion 22 may be fixedly connected to the first side portion 2111 and spaced apart from the second side portion 2112, the third side portion 2113, and the fourth side portion 2114. In this case, a first sub-gap 2131 may be formed between the mounting portion 22 and the second side portion 2112. A second sub-gap 2132 may be formed between the mounting portion 22 and the third side portion 2113. A third sub-gap 2133 may be formed between the mounting portion 22 and the fourth side portion 2114. The first sub-gap 2131, the second sub-gap 2132, and the third sub-gap 2133 may be interconnected and collectively constitute the gap 213. The plate portion 212 may cover the gap 213 from the second direction Z. In some embodiments, the plate portion 212 may further have an opening 212a. A portion of the mounting portion 22 may be exposed through the opening 212a.

[0170] Exemplarily, the bracket bottom 23 may include a first portion 231 and a second portion 232. The first portion 231 and the second portion 232 may be spaced apart in the first direction X. The first portion 231 and the second portion 232 may be bilaterally symmetrical structures. The first portion 231 and the second portion 232 may be located on opposite sides of the mounting portion 22 and fixedly connected to the mounting portion 22. The first portion 231 may be spaced apart from the second side 2112 of the bracket top 21 in the second direction Z. The second portion 232 may be spaced apart from the fourth side 2114 of the bracket top 21 in the second direction Z. At this time, the space between the first portion 231 and the first side 2111 and the space between the second portion 232 and the third side 2113 may together constitute a third avoidance space 2b.

[0171] For example, the first portion 231 may be provided with a fifth movable slot 2311 and a sixth movable slot 2312 spaced apart from each other. The openings of the fifth movable slot 2311 and the sixth movable slot 2312 may both face away from the bracket top 21. The second portion 232 may be provided with a seventh movable slot 2321 and an eighth movable slot 2322 spaced apart from each other. The openings of the seventh movable slot 2321 and the eighth movable slot 2322 may both face away from the bracket top 21. The fifth movable slot 2311, the sixth movable slot 2312, the seventh movable slot 2321, and the eighth movable slot 2322 may all have identical shapes and sizes.

[0172] Figure 26 is a partially exploded schematic diagram of the structure of the anti-shake motor 10a shown in Figure 6. Figure 27 is a partially cross-sectional schematic diagram of the structure of one embodiment of the anti-shake motor 10a shown in Figure 4, taken along line CC. Figure 28 is a partially cross-sectional schematic diagram of the structure of one embodiment of the anti-shake motor 10a shown in Figure 4, taken along line DD.

[0173] As shown in Figures 26 to 28, the first magnetic member 42 of the first driving mechanism 4 (please refer to Figure 6) can be roughly in the shape of an elongated strip. The first magnetic member 42 can be located on the side of the plate portion 212 of the top 21 of the bracket facing the bottom 23 of the bracket, and fixedly connected to the plate portion 212. At this time, at least a portion of the first magnetic member 42 can be located in the gap 213 between the mounting portion 22 and the top 21 of the bracket. The first magnetic member 42 can be spaced apart from the bottom 23 of the bracket in the second direction Z. Among them, the number of first magnetic members 42 can be two. At least a portion of one of the first magnetic members 42 can be located in the first sub-gap 2131, and spaced apart from the first portion 231 of the bottom 23 of the bracket. At least a portion of the other first magnetic member 42 can be located in the third sub-gap 2133, and spaced apart from the second portion 232 of the bottom 23 of the bracket.

[0174] For example, the first magnetic member 42 may include two first magnets 421 and a first magnetic conductive plate 422. The two first magnets 421 may be located on opposite sides of the first magnetic conductive plate 422. Both first magnets 421 may be fixedly connected to the first magnetic conductive plate 422. The two first magnets 421 may be spaced apart in the first direction X. It should be understood that the configuration of the first magnetic member 42 is quite diverse, and this embodiment does not specifically limit the configuration of the first magnetic member 42.

[0175] For example, the second driving mechanism 5 (see FIG6 ) may further include a second magnetic member 52 . The second magnetic member 52 may be roughly in the shape of an elongated strip. The second magnetic member 52 may be located on the side of the plate portion 212 of the bracket top 21 facing the bracket bottom 23 and fixedly connected to the plate portion 212 . At this time, at least a portion of the second magnetic member 52 may be located within the second sub-gap 2132 between the mounting portion 22 and the bracket top 21 . Part of the second magnetic member 52 and part of the mounting portion 22 may be stacked in the second direction Z. The second magnetic member 52 may include two second magnets 521 and a second magnetic conductive plate 522 . The two second magnets 521 may be located on opposite sides of the second magnetic conductive plate 522 . The two second magnets 521 may be fixedly connected to the second magnetic conductive plate 522 . The two second magnets 521 may be spaced apart in the third direction Y. It should be understood that the arrangement of the second magnetic member 52 is relatively diverse, and this embodiment does not specifically limit the arrangement of the second magnetic member 52 .

[0176] Figure 29 is a schematic diagram of the partial assembly structure of the anti-shake motor 10a shown in Figure 6. Figure 30 is a schematic diagram of a partial cross-section of the anti-shake motor 10a shown in Figure 4, taken along line EE. Figure 31 is a schematic diagram of a partial cross-section of the anti-shake motor 10a shown in Figure 4, taken along line FF.

[0177] As shown in Figures 29 to 31, the base bottom 33 of the movable base 3 can be movably connected to the bracket bottom 23 of the fixed bracket 2 via balls 8. For example, the openings of the four movable grooves of the base bottom 33 can be arranged in a one-to-one correspondence with the openings of the four movable grooves of the bracket bottom 23. Specifically, the first movable groove 332 can form a first ball rolling groove 81 together with the fifth movable groove 2311. The second movable groove 333 can form a second ball rolling groove 82 together with the sixth movable groove 2312. The third movable groove 334 can form a third ball rolling groove 83 together with the seventh movable groove 2321. The fourth movable groove 335 can form a fourth ball rolling groove 84 together with the eighth movable groove 2322. The balls 8 between the base bottom 33 and the bracket bottom 23 can roll within the ball rolling grooves not only in the first direction X but also in the third direction Y. In other words, the movable base 3 can move relative to the fixed bracket 2 in both the first direction X and the third direction Y. It can be understood that in this embodiment, only one layer of balls 8 is provided between the movable base 3 and the fixed bracket 2, so that the movable base 3 can move in multiple directions relative to the fixed bracket 2, and the movable base 3 is not easily stuck when moving relative to the fixed bracket 2.

[0178] In some embodiments, the anti-shake motor 10a may further include a magnetic sheet 101 and a magnet 102. The magnetic sheet 101 may be embedded in the base bottom 33 of the movable base 3. The magnet 102 may be embedded in the bracket bottom 23 of the fixed bracket 2. The projection of the magnet 102 along the second direction Z may cover at least a portion of the magnetic sheet 101. In this way, the magnetic sheet 101 may cooperate with the magnet 102 to generate a force. The movable base 3 may squeeze the fixed bracket 2 under the force between the magnetic sheet 101 and the magnet 102, thereby preventing the movable base 3 from tipping over when moving relative to the fixed bracket 2 in the XY plane, which is beneficial for improving the movement smoothness of the movable base 3 when moving relative to the fixed bracket 2. In other embodiments, the positions of the magnetic sheet 101 and the magnet 102 may be interchanged, that is, the magnetic sheet 101 may be embedded in the bracket bottom 23, and the magnet 102 may be embedded in the base bottom 33. This embodiment does not limit the specific positions of the magnetic sheet 101 and the magnet 102 .

[0179] Figure 32 is a schematic diagram of a partial cross-section structure of an embodiment of the structure shown in Figure 4 taken along CC. Figure 33 is a schematic diagram of a partial cross-section structure of an embodiment of the structure shown in Figure 4 taken along DD.

[0180] As shown in Figures 29, 32 and 33, the first through hole 331 of the movable base 3 can be connected to the installation space 2a of the fixed bracket 2 and is arranged opposite to the installation space 2a. That is, the photosensitive component 1 can be arranged opposite to the installation space 2a. The image sensor 11 can be arranged directly opposite the installation space 2a. The base top 31 of the movable base 3 can be located between the bracket top 21 and the bracket bottom 23 of the fixed bracket 2. The bracket bottom 23 of the fixed bracket 2 can be located between the base top 31 and the base bottom 33 of the movable base 3. At least a portion of the mounting portion 22 of the fixed bracket 2 can be located within the receiving space 3a of the movable base 3.

[0181] For example, the first portion 231 of the bracket bottom 23 can be located within the first escape space 3b between the first branch 311 of the base top 31 and the base bottom 33, and can be flexibly connected to the base bottom 33. The second portion 232 of the bracket bottom 23 can be located within the second escape space 3c between the third branch 313 of the base top 31 and the base bottom 33, and can be flexibly connected to the base bottom 33. The first branch 311 of the base top 31 can be located between the second side 2112 of the bracket top 21 and the first portion 231 of the bracket bottom 23, that is, located within the third escape space 2b of the fixed bracket 2. The third branch 313 of the base top 31 can be located between the fourth side 2114 of the bracket top 21 and the second portion 232 of the bracket bottom 23, that is, located within the third escape space 2b of the fixed bracket 2. In this case, the bracket top 21, base top 31, bracket bottom 23, and base bottom 33 can be stacked in sequence in the second direction Z.

[0182] For example, the second branch 312 of the base top 31 can be located on the side of the bracket top 21 facing the bracket bottom 23. The second branch 312 can be stacked with the mounting portion 22 in the second direction Z. The second driving mechanism 5 can be stacked with the mounting portion 22 in the second direction Z.

[0183] Fig. 34 is a partial cross-sectional view of the anti-shake motor 10a shown in Fig. 4 taken along line GG. Fig. 35 is a partial cross-sectional view of the anti-shake motor shown in Fig. 4 taken along line HH.

[0184] As shown in Figures 32 to 35 , the mounting portion 22 and the bracket bottom 23 of the fixed bracket 2 can semi-enclose the base frame 32 of the movable base 3. The base top 31 of the movable base 3 can semi-enclose the receiving space 3a. The base top 31 of the movable base 3 can semi-enclose the mounting portion 22 of the fixed bracket 2.

[0185] It is understandable that, compared to conventional anti-shake motors in which the movable base is entirely located inside the fixed bracket, or vice versa, the overall dimensions of the anti-shake motor in the first direction X and the third direction Y are larger, hindering the miniaturization of the anti-shake motor. In this embodiment, the anti-shake motor 10a is configured so that a portion of the movable base 3 can semi-enclose the fixed bracket 2, and a portion of the fixed bracket 2 can semi-enclose the movable base 3. This allows the movable base 3 and the fixed bracket 2 to mutually utilize each other's dimensional space in the first direction X and the third direction Y, thereby making the overall structure of the movable base 3 and the fixed bracket 2 more compact, thereby reducing the dimensions of the anti-shake motor 10a in the first direction X and the third direction Y, and facilitating the miniaturization of the anti-shake motor 10a.

[0186] Secondly, compared to conventional anti-shake motors in which the movable base and fixed bracket are stacked in the second direction Z, the overall thickness of the anti-shake motor is relatively thick, hindering its thinness. In this embodiment, by arranging the base bottom 33 and base top 31 of the movable base 3 and the bracket bottom 23 and bracket top 21 of the fixed bracket 2 to alternately stack in the second direction Z, the movable base 3 and the fixed bracket 2 can be nested within each other to utilize the space between them in the second direction Z. This makes the overall structure of the movable base 3 and the fixed bracket 2 more compact, which helps to reduce the size of the anti-shake motor 10a in the second direction Z and facilitates the miniaturization of the anti-shake motor 10a.

[0187] Referring again to Figures 29, 32, and 33, the third fixing portion 613 of the first circuit board 61 can be fixed to the surface of the plate portion 212 of the bracket top 21 facing away from the bracket bottom 23. In this case, the first bent section 614a of the first circuit board 61 can be located between the third side 2113 of the frame portion 211 of the bracket top 21 and the base bottom 33. The second bent section 614b of the first circuit board 61 can be located between the fourth side 2114 of the frame portion 211 and the base bottom 33. The third bent section 614c of the first circuit board 61 can be located on the side of the support portion 24 of the fixed bracket 2 facing away from the base top 31 of the movable base 3, and connected to the outer side surface of the support portion 24. In this way, the first circuit board 61 not only facilitates electrical signal transmission but also provides stiffness in the first direction X and the third direction Y for the overall movement of the movable base 3 and the photosensitive assembly 1. This minimizes the difference in stiffness between the various positions of the entire anti-shake motor 10a, effectively ensuring the stability of the image sensor 11's anti-shake performance in various positions during the movement of the anti-shake motor 10a and improving the anti-shake accuracy of the anti-shake motor 10a. Furthermore, the first circuit board 61 can be bent multiple times to wrap around a portion of the movable base 3, increasing its overall length and reducing its elastic modulus. This reduces the driving force required to move the movable base 3 relative to the fixed bracket 2, thereby reducing the power consumption of the anti-shake motor 10a during optical image stabilization.

[0188] For example, the fifth fixing portion 622 of the second circuit board 62 can be fixed to the surface of the plate portion 212 of the bracket top 21 that faces away from the bracket bottom 23. In this case, the fourth bent section 623a of the second circuit board 62 can be located between the third side 2113 of the frame portion 211 and the base bottom 33. The fifth bent section 623b of the second circuit board 62 can be located between the second side 2112 of the frame portion 211 and the base bottom 33. The sixth bent section 623c of the second circuit board 62 can be located on the side of the support portion 24 of the fixed bracket 2 that faces away from the base top 31 of the movable base 3, and connected to the outer side surface of the support portion 24. The second through hole 241 of the support portion 24 can be located between the sixth bent section 623c of the second circuit board 62 and the third bent section 614c of the first circuit board 61. In this way, the second circuit board 62 not only transmits electrical signals but also provides stiffness in the first direction X and the third direction Y for the combined movement of the movable base 3 and the photosensitive assembly 1, thereby improving the motion accuracy of the movable base 3 and the anti-shake accuracy of the anti-shake motor 10a. Furthermore, the second circuit board 62 can be bent multiple times to wrap around a portion of the movable base 3, increasing its overall length and reducing its own elastic modulus. This helps reduce the driving force required to move the movable base 3 relative to the fixed bracket 2, thereby reducing the power consumption of the anti-shake motor 10a during optical image stabilization.

[0189] It is understood that in this embodiment, the first surrounding portion 614 of the first circuit board 61 and the second surrounding portion 623 of the second circuit board 62 can be symmetrically structured (see Figure 6 ). The length of the first surrounding portion 614 can be equal to the length of the second surrounding portion 623. In this way, when the movable base 3 moves relative to the fixed bracket 2, the first circuit board 61 and the second circuit board 62 resist deformation and generate forces of equal magnitude and opposite directions, thereby offsetting each other. This can reduce the impact of the first circuit board 61 and the second circuit board 62 on the motion accuracy of the movable base 3 and improve the anti-shake accuracy of the anti-shake motor 10a.

[0190] In some embodiments, both the plate portion 212 and the support portion 24 may be provided with a retaining post 25. The third fixing portion 613 and the third bent section 614c of the first circuit board 61 may also be provided with a retaining hole 615. Thus, the retaining post 25 cooperates with the retaining hole 615 to facilitate positioning of the first circuit board 61 and the fixing bracket 2 during assembly, improving assembly efficiency.

[0191] In some embodiments, the first circuit board 61 and the second circuit board 62 may be integrally formed, that is, the first circuit board 61 and the second circuit board 62 may be the same circuit board. For example, the second fixing portion 612 of the first circuit board 61 may be integrally formed with the fourth fixing portion 621 of the second circuit board 62.

[0192] FIG36 is a schematic structural diagram of the first coil 41, the second coil 51, the third coil 43, the image sensor 11, the plurality of position sensors and the plurality of balls 8 shown in FIG32 from another perspective.

[0193] As shown in Figures 32, 33, and 36, the first magnetic member 42 can be positioned opposite the first coil 41 and the third coil 43. The first magnetic member 42 can be spaced apart from the first coil 41 in the second direction Z. When a signal is applied to the first coil 41, the first magnetic member 42 can cooperate with the first coil 41 to drive the movable base 3 and the photosensitive assembly 1 to move relative to the fixed bracket 2 in the first direction X. When a signal is applied to the third coil 43, the first magnetic member 42 can also cooperate with the third coil 43 to drive the movable base 3 to move relative to the fixed bracket 2 in the first direction X. The first position sensor 71 and the third position sensor 73 can both be positioned opposite the first magnetic member 42. Both the first position sensor 71 and the third position sensor 73 can be used to detect the magnetic field strength of the first magnetic member 42 at different positions to detect the position of the movable base 3. The driving force generated by the cooperation between the first coil 41 and the first magnetic member 42 is the first driving force. The driving force generated by the cooperation between the third coil 43 and the first magnetic member 42 is the second driving force. The direction of the first driving force and the direction of the second driving force may both be parallel to the first direction X.

[0194] For example, the projection of the geometric center of the rectangle formed by the center line connecting the two third coils 43 and the two first coils 41 on the plane where the image sensor 11 is located can coincide with the center of the image sensor 11. Among them, the first driving force generated by the cooperation of the first coil 41 and the first magnetic member 42 may not pass through the first axis R. The first coil 41 can also cooperate with the first magnetic member 42 to generate a first driving torque relative to the first axis R. The second driving force generated by the cooperation of the third coil 43 and the first magnetic member 42 may not pass through the first axis R. The third coil 43 can also cooperate with the first magnetic member 42 to generate a second driving torque relative to the first axis R. In this way, by controlling the direction and magnitude of the current input to the first coil 41 and the third coil 43, a variety of combined motion modes of moving and rotating the movable base 3 in different directions relative to the fixed bracket 2 can be realized. In other words, the cooperation of the first driving force and the second driving force can drive the movable base 3 to move relative to the fixed bracket 2 in the first direction X, and / or drive the movable base 3 to rotate around the first axis R relative to the fixed bracket 2. That is, the first driving mechanism 4 can drive the movable base 3 to drive the photosensitive component 1 to move along the first direction X and / or rotate around the first axis R relative to the fixed bracket 2.

[0195] In one embodiment, the third coil 43 and the first coil 41 can simultaneously input electrical signals of different directions (that is, the current direction of the third coil 43 is opposite to the current direction of the first coil 41), and the current input to the third coil 43 and the current input to the first coil 41 are different in magnitude. At this time, the first driving force and the second driving force are different in magnitude and opposite in direction. The first driving torque and the second driving torque are different in magnitude but the same in direction. At this time, the movable base 3 can move relative to the fixed bracket 2 along the first direction X under the joint action of the first driving force and the second driving force. When the first driving force is greater than the second driving force, the movable base 3 can move relative to the fixed bracket 2 in the direction of the first driving force. Conversely, the movable base can move relative to the fixed bracket 2 in the direction of the second driving force. At this time, the movable base 3 can rotate relative to the fixed bracket 2 around the first axis R under the joint action of the first driving torque and the second driving torque. The direction of rotation of the movable base 3 is the direction of the first driving torque and the second driving torque.

[0196] In one embodiment, the third coil 43 and the first coil 41 also simultaneously input electrical signals in the same direction (i.e., the current direction of the third coil 43 is the same as the current direction of the first coil 41), and the current input to the third coil 43 and the current input to the first coil 41 are different in magnitude. In this case, the first driving force and the second driving force are different in magnitude, but the same in direction. The first driving torque and the second driving torque are different in magnitude, but opposite in direction. In this case, the movable base 3 can move relative to the fixed support 2 along the first direction X under the combined action of the first driving force and the second driving force. The direction in which the movable base 3 moves is the direction of the first driving force and the second driving force. The movable base 3 can also rotate relative to the fixed support 2 around the first axis R under the combined action of the first driving torque and the second driving torque. When the first driving torque is greater than the second driving torque, the movable base 3 can rotate relative to the fixed support 2 around the first axis R in the direction of the first driving torque. Conversely, the movable base 3 can rotate relative to the fixed support 2 around the first axis R in the direction of the second driving torque.

[0197] As shown in Figures 32, 33 and 36, the second magnetic member 52 can be arranged opposite to the second coil 51. The second magnetic member 52 can be spaced apart from the second coil 51 in the second direction Z. When a signal is applied to the second coil 51, the second magnetic member 52 can cooperate with the second coil 51 to drive the movable base 3 to drive the photosensitive component 1 to move along the third direction Y relative to the fixed bracket 2. That is, the second driving mechanism 5 can drive the movable base 3 to drive the photosensitive component 1 to move along the third direction Y relative to the fixed bracket 2. The second position sensor 72 can be arranged opposite to the second magnetic member 52. The second position sensor 72 can be used to detect the magnetic field strength of the second magnetic member 52 at different positions to detect the position of the movable base 3.

[0198] For example, the geometric center of the rectangle formed by the center line of the four balls 8 can coincide with the center of the image sensor 11. In this way, the anti-shake accuracy of the anti-shake motor 10a is high, which is conducive to improving the imaging quality of the camera module.

[0199] It is understood that the movable base 3 in this embodiment can drive the image sensor 11 to move relative to the fixed bracket 2 in the first direction X and the third direction Y, thereby achieving anti-shake for the anti-shake motor 10a in the first direction X and the third direction Y. Furthermore, the anti-shake motor 10a in this embodiment is further provided with a third coil 43 that cooperates with the first magnetic member 42 to generate a second driving force. The magnitude of this second driving force is different from the magnitude of the first driving force generated by the cooperation of the first coil 41 and the first magnetic member 42. Thus, under the combined action of the first and second driving forces, the movable base 3 can also drive the photosensitive component 1 to rotate relative to the fixed bracket 2 about the first axis R, thereby compensating for vibration generated when the electronic device 1000 rotates about an axis parallel to the second direction Z. This enables the anti-shake motor 10a to achieve three-axis anti-shake, covering a wider range of anti-shake scenarios, thereby improving imaging quality and enhancing the user experience.

[0200] In other embodiments, the first magnetic member 42 may further include a first sub-magnetic member and a second sub-magnetic member that are spaced apart from each other. The first sub-magnetic member and the second sub-magnetic member may be disposed opposite to the first coil 41 and the third coil 43 respectively.

[0201] In some other embodiments, the winding plane of the first coil 41 may also be perpendicular to the planes of the first direction X and the third direction Y. In this case, the first magnetic member 42 and the first coil 41 may also be spaced apart in the first direction X.

[0202] Fig. 37 is a schematic cross-sectional view of the anti-shake motor 10a shown in Fig. 4 taken along line CC. Fig. 38 is a schematic cross-sectional view of the anti-shake motor 10a shown in Fig. 4 taken along line DD.

[0203] As shown in Figures 37 and 38, the anti-shake motor 10a may further include a housing 103. The movable base 3 and at least a portion of the fixed bracket 2 may be installed in the internal space 103a of the housing 103. The housing 103 may include a frame 1031 and a bottom plate 1032. The bottom plate 1032 may be fixedly connected to the frame 1031 and, together with the frame 1031, enclose the internal space 103a of the housing 103. The bracket top 21 of the fixed bracket 2 may be fixedly connected to the frame 1031. The housing 103 may have a third through hole 1033. The third through hole 1033 may communicate with the installation space 2a of the fixed bracket 2. The movable base 3 and the photosensitive component 1 may both be located in the internal space 103a of the housing 103. The movable base 3 may be spaced apart from the bottom plate 1032 of the housing 103. The photosensitive component 1 may be spaced apart from the bottom plate 1032 of the housing 103. The third fixing portion 613 of the first circuit board 61 and the fifth fixing portion 622 of the second circuit board 62 can be located on the outside of the housing 103. The third fixing portion 613 and the fifth fixing portion 622 can be used to electrically connect to other devices other than the anti-shake motor 10a (such as a power supply, a driver chip, etc.). The second connecting portion 93 of the elastic member 9 can be fixedly connected to the housing 103 (please refer to Figure 22). In this way, when the movable base 3 drives the photosensitive component 1 to move relative to the fixed bracket 2, the elastic member 9 can provide stiffness values ​​in the first direction X and the third direction Y for the overall movement of the movable base 3 and the photosensitive component 1, which is beneficial to improve the movement accuracy of the movable base 3 and improve the anti-shake accuracy of the anti-shake motor 10a.

[0204] It will be appreciated that in this embodiment, the anti-shake motor 10a is positioned so that the first coil 41 of the first drive mechanism 4 is spaced apart from the photosensitive component 1 in the second direction Z. This allows the first drive mechanism 4 to be located on the side of the photosensitive component 1 facing the installation space 2a. Furthermore, the projection of the first drive mechanism 4 onto the plane of the sensor circuit board 12 can partially cover the sensor circuit board 12. This spacing of the first coil 41 from the sensor circuit board 12 in the second direction Z allows the length and / or width of the sensor circuit board 12 to be reduced, effectively reducing the length and / or width of the movable base 3 and the fixed bracket 2. This reduces the length and / or width of the entire anti-shake motor 10a, facilitating a compact design of the anti-shake motor 10a. Furthermore, the first coil 41 can be located on the side of the photosensitive component 1 facing the installation space 2a, allowing the first drive mechanism 4 to utilize the space provided by the optical element 10b in the second direction Z, facilitating a compact design of the anti-shake motor 10a.

[0205] Secondly, the projection of the first drive mechanism 4 onto the plane of the sensor circuit board 12 can also cover at least a portion of the electronic components 13 disposed on the sensor circuit board 12. This allows the first drive mechanism 4 to utilize the length and / or width of the electronic components 13, effectively reducing the length and / or width of the sensor circuit board 12, as well as the length and / or width of the movable base 3 and the fixed bracket 2. This reduces the length and / or width of the entire anti-shake motor 10a, facilitating a compact design of the anti-shake motor 10a. Furthermore, compared to anti-shake motors in which the first coil is disposed on the sensor circuit board and the electronic components are located within the coil hole of the first coil, a portion of the first coil remains between the electronic components and the image sensor, resulting in a greater distance between the electronic components and the image sensor and a larger overall size of the sensor circuit board, hindering the compact design of the anti-shake motor. In this embodiment, the first coil 41 and the photosensitive component 1 are arranged in the second direction Z, allowing the electronic components 13 to be positioned as close as possible to the image sensor 11, thereby reducing the size of the sensor circuit board 12 and, consequently, facilitating a compact design of the anti-shake motor 10a.

[0206] Secondly, in this embodiment, the second coil 51 can be spaced apart from the photosensitive component 1 and arranged in the second direction Z. At the same time, a portion of the second driving mechanism 5 and a portion of the mounting portion 22 of the fixed bracket 2 can be stacked in the second direction Z. In this way, the second coil 51 can utilize the dimensions of the mounting space 2a in the third direction Y, allowing the movable base 3 to utilize the dimensions of the fixed bracket 2 in the third direction Y. This makes the movable base 3 and the fixed bracket 2 more compact in the third direction Y, which helps to reduce the size of the entire anti-shake motor 10a in the third direction Y and facilitates the miniaturization of the anti-shake motor 10a.

[0207] Furthermore, in this embodiment, at least a portion of the first drive mechanism 4 and at least a portion of the second drive mechanism 5 can be located around the perimeter of the installation space 2a. This allows the first drive mechanism 4 and the second drive mechanism 5 to utilize the space provided by the installation space 2a in the second direction Z, making the overall structure of the anti-shake motor 10a in the second direction Z more compact. This helps reduce the overall size of the anti-shake motor 10a in the second direction Z and facilitates miniaturization of the anti-shake motor 10a.

[0208] In addition, the anti-shake motor 10a in this embodiment may further include a dielectric layer 63. The number of first coils 41 may be multiple. Multiple first coils 41 may be embedded in the dielectric layer 63, and the first coils 41 and the dielectric layer 63 may be integrally formed, thereby ensuring the surface flatness and thickness consistency of the multiple first coils 41, thereby effectively ensuring the consistency of the spacing between the multiple first coils 41 and the first magnetic member 42, so that the magnitude of the force generated between each first coil 41 and the first magnetic member 42 is the same, thereby avoiding affecting the movement accuracy of the movable base 3 due to uneven force.

[0209] Figure 39 is a schematic diagram of a portion of the structure of the camera module 100 shown in Figure 2 in some embodiments. Figure 40 is a schematic diagram of signal transmission between the first driver chip 1002 and the second driver chip 1003 shown in Figure 39. Figure 41 is a schematic diagram of signal transmission between the first driver chip 1002 and the second driver chip 1003 shown in Figure 39 in another embodiment.

[0210] In some embodiments, as shown in Figures 39 to 41, the camera module 100 may further include a drive motor 30a. The optical folding element 30b may be mounted on the drive motor 30a. The drive motor 30a may be used to drive the optical folding element 30b to rotate in different directions (for example, around the X-axis and / or around the Y-axis) to achieve optical image stabilization of the camera module 100. At this time, the optical folding element 30b and the drive motor 30a may together constitute the second anti-shake component 30 of the camera module 100. In this way, by combining the first anti-shake component 10 and the second anti-shake component 30 to achieve optical image stabilization, it is beneficial to improve the anti-shake angle of the camera module 100, and the user experience is better. Secondly, the movable base 3 of the anti-shake motor 10a can also drive the photosensitive component 1 to rotate relative to the fixed bracket 2 around the first axis R (please refer to Figure 36), so that the camera module 100 can simultaneously achieve optical image stabilization through the first anti-shake component 10 and the second anti-shake component 30. On the basis of increasing the anti-shake angle, it can also suppress the image rotation generated by the second anti-shake component 30 when driving the optical folding element 30b to rotate, which is beneficial to improving imaging quality and enhancing user experience. At the same time, the movable base 3 of the anti-shake motor 10a can also drive the photosensitive component 1 to rotate relative to the fixed bracket 2 around the first axis R and can also compensate for the vibration generated when the electronic device 1000 rotates around an axis parallel to the second direction Z, so that the anti-shake motor 10a can achieve three-axis image stabilization. The anti-shake motor 10a can cover more anti-shake scenarios, which is beneficial to improving imaging quality and enhancing user experience.

[0211] Exemplarily, the camera module 100 may further include a main circuit board 1001, a first driver chip 1002, and a second driver chip 1003. The main circuit board 1001 may be electrically connected to the anti-shake motor 10a (for example, the first circuit board 61 and the second circuit board 62 electrically connected to the anti-shake motor 10a), the drive motor 30a, and an external power supply. The first driver chip 1002 and the second driver chip 1003 may both be fixed to the main circuit board 1001 and both be electrically connected to the main circuit board 1001. Among them, the first driver chip 1002 may be used to control the anti-shake motor 10a of the first anti-shake component 10. The second driver chip 1003 may be used to control the drive motor 30a of the second anti-shake component 30.

[0212] Exemplarily, the electronic device 1000 further includes a gyroscope. The gyroscope can be electrically connected to the first driver chip 1002 and the second driver chip 1003 at the same time. The gyroscope can transmit signals to the first driver chip 1002 and the second driver chip 1003 at the same time. Exemplarily, when the electronic device 1000 shakes, the gyroscope can obtain the posture information of the electronic device 1000 at this time. The gyroscope can split the posture information into first position information and second position information through a filtering algorithm, and transmit the first position information to the first driver chip 1002, and transmit the second position information to the second driver chip 1003. After the first driver chip 1002 obtains the first position information, it can control the anti-shake motor 10a of the first anti-shake component 10 to drive the optical element 10b to the first target position according to the first position information, thereby realizing optical image stabilization of the first anti-shake component 10. After obtaining the second position information, the second driver chip 1003 can control the drive motor 30a of the second anti-shake assembly 30 based on the obtained second position information to drive the optical folding element 30b to the second target position, thereby achieving optical image stabilization of the second anti-shake assembly 30. Specifically, the first anti-shake assembly 10 can achieve high-frequency, small-angle image stabilization, while the second anti-shake assembly 30 can achieve low-frequency, large-angle image stabilization.

[0213] It can be understood that in this embodiment, a gyroscope is set to obtain the posture information of the electronic device 1000, and the posture information is split into first position information and second position information. The first driver chip 1002 and the second driver chip 1003 respectively drive the corresponding motors for anti-shake according to the first position information and the second position information, so that the camera module 100 can fully utilize the anti-shake performance of the two anti-shake components, improve the anti-shake efficiency, and enhance the user experience.

[0214] In other embodiments, as shown in FIG41 , the gyroscope may be electrically connected only to the first driver chip 1002. The first driver chip 1002 is electrically connected to the second driver chip 1003. When the electronic device 1000 shakes, the gyroscope may obtain the current posture information of the electronic device 1000. The gyroscope may transmit the posture information directly to the first driver chip 1002. After the first driver chip 1002 obtains the posture information from the gyroscope, it may use a filtering algorithm to separate the posture information into first position information and second position information. The first driver chip 1002 may control the anti-shake motor 10a of the first anti-shake component 10 based on the first position information to drive the optical element 10b to the first target position, thereby achieving optical image stabilization of the first anti-shake component 10. The first driver chip 1002 may also transmit the second position information to the second driver chip 1003. The second driver chip 1003 may control the drive motor 30a of the second anti-shake component 30 based on the obtained second position information to drive the optical folding element 30b to the second target position, thereby achieving optical image stabilization of the second anti-shake component 30.
