[0001] This application relates to the field of imaging technology, and particularly to an anti-shake motor, a camera module, and an electronic device. Background Art
[0002] With the popularization and development of electronic devices such as smart phones and tablet computers, mobile phone photography has become a commonly used shooting method for people, and users have higher and higher requirements for the shooting quality of electronic devices. When users perform shooting operations, the electronic device is prone to shake, seriously affecting the shooting quality. Therefore, an anti-shake structure is usually required in the camera module. However, the anti-shake structure in the current camera module is relatively large in volume, which is not conducive to the miniaturization of the overall camera module. Summary of the Invention
[0003] Embodiments of this application provide an anti-shake motor, a camera module, and an electronic device, aiming to provide an anti-shake motor with a relatively small volume, a camera module including the anti-shake motor, and an electronic device including the camera module.
[0004] In a first aspect, an anti-shake motor is provided. The anti-shake motor includes:
[0005] A fixed bracket having an installation space for installing an optical element;
[0006] A movable base movably connected to the fixed bracket;
[0007] A photosensitive component 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
[0008] A first driving mechanism including 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 disposed 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 along a first direction;
[0009] Wherein, the first coil and the photosensitive component are spaced apart in a second direction and are located on a 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 a part of the sensor circuit board.
[0010] It can be understood that in this embodiment, the anti-shake motor arranges the first coil of the first driving mechanism and the photosensitive component at intervals in the second direction, and the first driving mechanism can be located on the side of the photosensitive component facing the installation space. At the same time, the projection of the first driving 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 arranged at intervals in the second direction, so that the length and / or width dimension of the sensor circuit board can be smaller, thereby effectively reducing the length and / or width dimensions of the movable base and the fixed bracket, so as to save the length and / or width dimensions of the entire anti-shake motor, which is beneficial to realizing the miniaturization setting 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 driving mechanism can also utilize the dimension space of the optical element in the second direction, which is beneficial to realizing the miniaturization setting of the anti-shake motor.
[0011] In a possible implementation manner, the photosensitive component further includes electronic devices, the electronic devices are fixed on the sensor circuit board and are arranged at intervals 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 devices.
[0012] It can be understood that the projection of the first driving mechanism on the plane where the sensor circuit board is located can also cover at least part of the electronic devices provided on the sensor circuit board. In this way, the first driving mechanism can also utilize the length and / or width dimension space of the electronic devices, thereby effectively reducing the length and / or width dimensions of the sensor circuit board, as well as reducing the length and / or width dimensions of the movable base and the fixed bracket, so as to save the length and / or width dimensions of the entire anti-shake motor, which is beneficial to realizing the miniaturization setting of the anti-shake motor. At the same time, compared with the anti-shake motor in which the first coil is arranged on the sensor circuit board and the electronic devices are located in the coil holes of the first coil, there is still part of the first coil between the electronic devices and the image sensor, so that the distance between the electronic devices and the image sensor is relatively far, and the overall size of the sensor circuit board is large, which is not conducive to the miniaturization setting of the anti-shake motor. In this embodiment, the first coil and the photosensitive component are arranged in the second direction, so that the electronic devices can be arranged as close as possible to the image sensor, which is beneficial to reducing the size of the sensor circuit board, and thus is beneficial to realizing the miniaturization setting of the anti-shake motor.
[0013] In a possible implementation manner, the first driving mechanism and the optical element installed on the fixed bracket are arranged at intervals in the first direction. In this way, the first driving mechanism can also utilize the dimension space of the optical element in the second direction, which is beneficial to realizing the miniaturization setting of the anti-shake motor.
[0014] In a possible implementation manner, the photosensitive component and the first coil are fixed on two opposite sides of the movable base. In this way, the photosensitive component and the first coil can be arranged at intervals in the second direction, which is beneficial to realizing the miniaturization setting of the anti-shake motor.
[0015] In a possible implementation, the movable base has a receiving space for receiving part of the fixed bracket and at least part of the optical element mounted on the fixed bracket. The movable base includes a base top, a base frame portion, and a base bottom. The base frame portion is connected between the base top and the base bottom, and the receiving space is located inside the base frame portion. 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 and the photosensitive component can be spaced apart in the second direction, which is beneficial to the miniaturization of the anti-shake motor.
[0016] In a possible implementation, the base bottom has a first through hole that communicates the receiving space and the installation space of the fixed bracket. The photosensitive component is fixedly connected to the surface of the base bottom facing away from the base top, and the image sensor is aligned with 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, which is convenient for assembly.
[0017] In a possible implementation, the base top includes a first branch, a second branch, and a third branch. The first branch and the third branch are spaced apart in the first direction, and the second branch is connected between the first branch and the third branch. The base top semi-surrounds part of the optical element. In this way, by arranging the base top to semi-surround part of the optical element, the base top can also utilize the dimensional space of the optical element in the second direction, which is beneficial to the thinning of the anti-shake motor.
[0018] In a possible implementation, the movable base further has a first avoidance space located between the base top and the base bottom and outside the base frame portion, and a part of the fixed bracket is located in the first avoidance space. In this way, compared with the general anti-shake motor in which the whole movable base is located inside the fixed bracket, or the whole fixed bracket is located inside the movable base, the overall size of the anti-shake motor is larger. In this embodiment, a part of the fixed bracket can be located in the first avoidance space, making the overall structure of the fixed bracket and the movable base more compact, which is beneficial to the miniaturization of the anti-shake motor.
[0019] In a possible implementation, the base frame portion 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 the first direction, the second side portion is on the same side of the first side portion and the third side portion, and is fixedly connected to the first side portion and the third side portion. The surface of the first side portion facing away from the second side portion faces the first avoidance space, the first avoidance space communicates with the receiving space, and part of the fixed bracket is located on the side of the first side portion facing away from the second side portion. In this way, the fixed bracket can also utilize the thickness dimensional space of the first side portion of the base frame portion, which is beneficial to the miniaturization of the anti-shake motor.
[0020] In a possible implementation, the fixed bracket includes a bracket top, a mounting portion, and a bracket bottom. The bracket top and the bracket bottom are spaced apart in the second direction. The mounting portion connects the bracket top and the bracket bottom. The mounting portion has a mounting space, and at least part of the mounting portion is located in the receiving space. The bracket bottom is movably connected to the base bottom through balls, and the first magnetic member is fixed to the bracket top. In this way, the first magnetic member can be spaced apart from the photosensitive component in the second direction, which is beneficial to the miniaturization of the anti-shake motor.
[0021] In a possible implementation, part of the mounting portion and part of the base top are stacked in the second direction. In this way, the base top can utilize the dimensional space of the mounting portion in the first direction and / or the third direction, which is beneficial to the miniaturization of the anti-shake motor.
[0022] In a possible implementation, the bracket bottom is located between the base bottom and the base top, and the base top is located between the bracket bottom and the bracket top.
[0023] It can be understood that, compared with the general anti-shake motor in which the movable base and the fixed bracket are stacked in the second direction, the overall thickness of the anti-shake motor is relatively thick, which is not conducive to the thin-type setting of the anti-shake motor. In this embodiment, by arranging the base bottom and the base top of the movable base and the bracket bottom and the bracket top of the fixed bracket to be alternately stacked in the second direction, the movable base and the fixed bracket can be mutually embedded to utilize the dimensional space of each other in the second direction, so that the overall structure of the movable base and the fixed bracket is relatively compact, which is beneficial to saving the size of the anti-shake motor in the second direction and is beneficial to the miniaturization of the anti-shake motor.
[0024] In a possible implementation, the bracket top 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. Part of the mounting portion is located inside the frame portion. A part of the frame portion is fixedly connected to the mounting portion, and another part of the frame portion is spaced apart from the mounting portion to form a gap. The first magnetic member is fixedly connected to the plate portion, and at least part of the first magnetic member is located in the gap. In this way, the first magnetic member can utilize the thickness dimensional space of the optical element, which is beneficial to the thin-type setting of the anti-shake motor.
[0025] In a possible implementation, the anti-shake motor further includes a first circuit board. The first circuit board 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, the other end of the first surrounding portion is fixedly connected to the third fixing portion, the first surrounding portion is further fixedly connected to the first fixing portion, and the first surrounding portion surrounds a part of the movable base.
[0026] It can be understood that in addition to realizing the transmission of electrical signals, the first circuit board in this embodiment can also provide stiffness values in different directions for the overall movement of the movable base and the photosensitive component, so that the difference values of the entire anti-shake motor in different postures are relatively small, which is beneficial to ensuring the stability of the anti-shake performance of the image sensor in different postures during the movement of the anti-shake motor and improving the anti-shake accuracy of the anti-shake motor. At the same time, the first circuit board can be bent multiple times to surround a part of the movable base, so that the overall length of the first circuit board is relatively long, so as to reduce the elastic coefficient of the first circuit board itself, which is beneficial to reducing the driving force required for the relative movement of the movable base with respect to the fixed bracket and is beneficial to reducing the power consumption when the anti-shake motor performs optical image stabilization.
[0027] In a possible implementation, the fixed bracket further includes a support portion. The support portion is connected between the top and the bottom of the bracket. The support portion is connected to the mounting portion. The support portion has a second through hole, and the second through hole communicates with the installation 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 is fixedly connected to the first fixing portion and the second fixing portion. The third bending section is fixedly connected to the third fixing portion. The first bending section is spaced from the movable base in the third direction. The second bending section is spaced from the movable base in the first direction. The third bending section is located on the side of the movable base facing away from the first bending section and is fixedly connected to the support portion. The third direction intersects the first direction and is perpendicular to the plane where the image sensor is located.
[0028] It can be understood 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 relatively long, thereby reducing the elastic coefficient of the first circuit board itself, which is beneficial to reducing the driving force required for the relative movement of the movable base with respect to the fixed bracket, and is beneficial to reducing the power consumption during optical image stabilization of the image stabilization motor. Secondly, the first surrounding portion can 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, making the difference value of the entire image stabilization motor in different postures relatively small, which is beneficial to ensuring the stability of the image stabilization performance of the image sensor in different postures during the movement of the image stabilization motor and improving the image stabilization accuracy of the image stabilization motor. In addition, the supporting portion can also provide support and fixation for the first circuit board, thereby avoiding interference of the first circuit board on the movable base during the movement of the movable base.
[0029] In a possible implementation manner, the image stabilization motor further includes a second circuit board, which includes 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 is electrically connected to the sensor circuit board. The fifth 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 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 surrounds part of the movable base, and part of the second surrounding portion and part of the first surrounding portion are located on opposite sides of the movable base.
[0030] It can be understood that in addition to realizing the transmission of electrical signals, the second circuit board in this embodiment can also provide stiffness values in the first direction and the third direction for the overall movement of the movable base and the photosensitive component, so as to improve the movement accuracy of the movable base and the image stabilization accuracy of the image stabilization motor. At the same time, the second circuit board can be bent multiple times to surround part of the movable base, so that the overall length of the second circuit board is relatively long, thereby reducing the elastic coefficient of the second circuit board itself, which is beneficial to reducing the driving force required for the relative movement of the movable base with respect to the fixed bracket, and is beneficial to reducing the power consumption during optical image stabilization of the image stabilization motor.
[0031] Secondly, the first surrounding portion of the first circuit board and the second surrounding portion of the second circuit board in this embodiment can be of a symmetric structure. 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 circuit board and the second circuit board can generate forces with the same magnitude and opposite directions due to resisting deformation to cancel each other out, thereby reducing the influence of the first circuit board and the second circuit board on the movement accuracy of the movable base and improving the image stabilization accuracy of the image stabilization motor.
[0032] In a possible implementation, the second surrounding portion includes a fourth bending segment, a fifth bending segment, and a sixth bending segment connected in sequence. The fourth bending segment is fixedly connected to the fourth fixing portion, and the sixth bending segment is fixedly connected to the fifth fixing portion. The fourth bending segment is located on one side of the top of the base facing the first bending segment, the fifth bending segment is located on the side of the movable base facing away from the second bending segment, and the sixth bending segment is located on the side of the movable base facing away from the fourth bending segment and is fixedly connected to the supporting portion. The second through hole of the supporting portion is located between the third bending segment and the sixth bending segment.
[0033] It can be understood that the second circuit board in this embodiment can be bent multiple times to surround part of the movable base, so that the overall length of the second circuit board is relatively long, thereby reducing the elastic coefficient of the second 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 when the anti-shake motor performs optical anti-shake. Secondly, the second surrounding portion can surround part of the movable base, so that the second surrounding portion can also provide stiffness values in different directions for the overall movement of the movable base and the photosensitive component, making the difference value of the entire anti-shake motor in different postures relatively small, which is beneficial to ensuring the stability of the anti-shake performance of the image sensor in different postures during the movement of the anti-shake motor and improving the anti-shake accuracy of the anti-shake motor.
[0034] In a possible implementation, the projection of the fourth bending segment on the plane where the first bending segment is located covers part of the first bending segment, and the fourth bending segment and the first bending segment are spaced apart in the second direction.
[0035] It can be understood that the first bending segment of the first circuit board and the fourth bending segment of the second circuit board in this embodiment have an overlapping part, so that the lengths of the first circuit board and the second circuit board can be extended, which is beneficial to reducing the elastic coefficients of the first circuit board and the second circuit board themselves, beneficial to reducing the driving force required for the movable base to move relative to the fixed bracket, and beneficial to reducing the power consumption when the anti-shake motor performs optical anti-shake. Secondly, the first bending segment of the first circuit board can be opposite to part of the fourth bending segment of the second circuit board and is also spaced apart from the fourth bending segment of the second circuit board in the third direction, so as to effectively avoid collision and mutual interference between the two, which may affect the normal operation of the anti-shake motor.
[0036] In a possible implementation, the anti-shake motor further includes a first position sensor. The top of the base has a first installation groove, and the opening of the first installation groove faces the first coil. The first position sensor is received in the first installation groove. In this way, by providing the first installation groove to receive the first position sensor, it is possible to avoid the collision between the first magnetic member and the first position sensor, resulting in device failure, and it is beneficial to extend the service life of the anti-shake motor.
[0037] In a possible implementation, the first driving mechanism further includes a third coil. The third coil is fixed to the top of the base and is spaced from the first coil in three directions. The third coil is disposed opposite to the first magnetic member. The third coil and the first magnetic member cooperate to drive the movable base to move relative to the fixed bracket in the first direction. The third direction intersects the first direction and is perpendicular to the plane where the image sensor is located. The first coil and the third coil jointly cooperate with the first magnetic member to drive the movable base to move relative to the fixed bracket in the first direction and / or drive the movable base to rotate relative to the fixed bracket about the light incident axis of the image sensor.
[0038] It can be understood that the movable base in this embodiment can drive the image sensor to move relative to the fixed bracket in the first direction together, so as to achieve anti-shake of the anti-shake motor in the first direction. On this basis, the anti-shake motor in this embodiment is further provided with a third coil and a first magnetic member cooperating 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 member. In this way, the movable base can also drive the photosensitive component to rotate relative to the fixed bracket about the first axis under the combined action of the first driving force and the second driving force, so as to compensate for the shake generated when the electronic device rotates about the axis parallel to the second direction, so that the anti-shake motor can achieve multi-axis anti-shake, the anti-shake motor can cover more anti-shake scenarios, which is beneficial to improving the imaging quality and enhancing the user experience.
[0039] In a possible implementation, the anti-shake motor further includes a second driving mechanism. The second driving mechanism includes 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 is disposed opposite to the second magnetic member. The second coil and the second magnetic member cooperate to drive the movable base to move relative to the fixed bracket in the third direction. The third direction intersects the first direction and is perpendicular to the plane where the image sensor is located. The second coil is spaced from the photosensitive component 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 together, so as to achieve anti-shake of the anti-shake motor in the third direction, so that the anti-shake motor can achieve multi-axis anti-shake, the anti-shake motor can cover more anti-shake scenarios, which is beneficial to improving the imaging quality and enhancing the user experience.
[0040] In a possible implementation, the second driving mechanism is spaced from the optical element mounted on the fixed bracket in the third direction.
[0041] In this way, by setting the second driving mechanism to be spaced from the optical element in the third direction, the second driving mechanism can also utilize the dimensional space of the optical element in the second direction, which is beneficial to realizing the thin-type setting of the anti-shake motor.
[0042] In a possible implementation, the second coil is fixed to the side of the movable base facing away from the photosensitive component. In this way, the second coil and the photosensitive component can be spaced apart in the second direction, which is beneficial to reducing the size of the sensor circuit board, thereby reducing the size of the anti-shake motor and facilitating the miniaturization of the anti-shake motor.
[0043] In a possible implementation, the anti-shake motor further includes a dielectric layer board, and both the first coil and the second coil are embedded in the dielectric layer board, and the material of the dielectric layer board is an insulating material.
[0044] It can be understood that the anti-shake motor in this embodiment may further include a dielectric layer board. Both the first coil and the second coil can be embedded in the dielectric layer board, which is beneficial to improving the preparation precision of the first coil and the second coil, ensuring the flatness of the surface of the first coil and the surface of the second coil, and ensuring the thickness consistency of the first coil and the second coil. At the same time, the first coil, the second coil, and the dielectric layer board can be assembled together as a whole on the top of the base, which is beneficial to improving the assembly precision.
[0045] In a 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 component are both located inside the housing. The housing has a third through hole, and the third through hole communicates with the installation space. The elastic member is fixedly connected between the movable base and the housing. In this way, when the movable base drives the photosensitive component to move relative to the fixed bracket together, the elastic member can provide stiffness values in the first direction and the third direction for the overall movement of the movable base and the photosensitive component, which is beneficial to improving the movement precision of the movable base and the anti-shake precision of the anti-shake motor.
[0046] In a second aspect, a camera module is provided. The camera module includes an optical element and the above-mentioned anti-shake motor, and the optical element is installed on the fixed bracket of the anti-shake motor.
[0047] It can be understood that in this embodiment, the anti-shake motor arranges the first coil of the first driving mechanism and the photosensitive component at intervals in the second direction. The first driving mechanism can be located on the side of the photosensitive component facing the installation space. At the same time, the projection of the first driving 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 arranged at intervals in the second direction, so that the length and / or width dimension of the sensor circuit board can be smaller, thereby effectively reducing the length and / or width dimensions of the movable base and the fixed bracket, saving the length and / or width dimensions of the entire anti-shake motor, and facilitating 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 driving mechanism can also utilize the dimensional space of the optical element in the second direction, facilitating the miniaturization of the anti-shake motor.

The first driving mechanism can be located on the side of the photosensitive component facing the installation space. At the same time, the projection of the first driving 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 arranged at intervals in the second direction, so that the length and / or width dimension of the sensor circuit board can be smaller, thereby effectively reducing the length and / or width dimensions of the movable base and the fixed bracket, saving the length and / or width dimensions of the entire anti-shake motor, and facilitating 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 driving mechanism can also utilize the dimensional space of the optical element in the second direction, facilitating the miniaturization of the anti-shake motor.

[0099] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
[0100] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly defined 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 and the relative positional relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only references to the directions in the drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the embodiments of the present application. "Plurality" means at least two.
[0101] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of such features.
[0102] In the embodiments of the present application, "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.
[0103] The reference to "one embodiment" or "some embodiments" etc. described in this specification means that in one or more embodiments of the present application, specific features, structures, or characteristics described in connection with that embodiment are included.

The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.
[0104] It can be understood that the specific embodiments described herein are only for explaining the related invention and not for limiting the invention. Additionally, it should be noted that for ease of description, only parts related to the invention are shown in the drawings.
[0105] Figure 1It is a schematic structural diagram of the electronic device 1000 provided by an embodiment of the present application in some embodiments. Figure 2 It is Figure 1 A schematic cross-sectional structure diagram in an embodiment of the electronic device 1000 shown in the figure cut along A-A.
[0106] As Figure 1 and Figure 2 shown, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, etc., devices with a camera module. Figure 1 The electronic device 1000 in the illustrated embodiment will be described by taking a mobile phone as an example.
[0107] As Figure 1 and Figure 2 shown, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. Among them, the camera module 100 can be a rear camera module or a front camera module. It should be noted that Figure 1 and the relevant drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 1 and the respective drawings below. In addition, when the electronic device 1000 is a device in some other forms, the electronic device 1000 may not include the screen 300.
[0108] 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 the Z-axis, which is the second direction Z. The width direction of the electronic device 1000 is the Y-axis, which is the third direction Y. It can be understood that the coordinate system setting of the electronic device 1000 can be flexibly set according to specific actual needs.
[0109] In this embodiment, the device housing 200 may include a frame 2001 and a rear cover 2002. The rear cover 2002 is fixed to the frame 2001. Exemplarily, the rear cover 2002 can be fixedly connected to the frame 2001 by adhesive. The rear cover 2002 can also be an integrally formed structure with the frame 2001, that is, the rear cover 2002 and the frame 2001 are a single integral structure.
[0110] In addition, the screen 300 can be located on the side of the frame 2001 away from the rear cover 2002. At this time, the screen 300 and the rear cover 2002 are respectively located on both sides of the frame 2001. The screen 300, the frame 2001 and the rear cover 2002 jointly enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place the components of the electronic device 1000, such as a battery, a receiver or a microphone, etc. Among them, the screen 300 can be a flat screen or a curved screen.
[0111] Exemplarily, 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 rear cover 2002. The rear cover 2002 can be provided with a light-transmitting hole 2003. The shape of the light-transmitting hole 2003 is not limited to the Figure 1 circular shape shown. The light-transmitting hole 2003 connects the interior of the electronic device 1000 to the outside of the electronic device 1000. The light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 2003. The camera module 100 can collect the ambient light entering the interior of the electronic device 1000.
[0112] Figure 3 Yes Figure 2 is a schematic structural diagram of the first anti-shake component 10 of the camera module 100 shown in some embodiments. Figure 4 Yes Figure 3 is an exploded structural diagram of the first anti-shake component 10 shown in some embodiments.
[0113] As Figures 2 to 4 shown, the camera module 100 can include an optical folding element 30b, a focusing component 20 and a first anti-shake component 10 arranged in sequence along the optical axis direction. In this embodiment, the optical folding element 30b, the focusing component 20 and the first anti-shake component 10 can be arranged in sequence in the third direction Y. Exemplarily, the optical folding element 30b can be a reflecting prism or a reflecting flat mirror. The light outside the electronic device 1000 can 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 component 20 and the first anti-shake component 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 component 20.
[0114] 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 reflecting prism. The anti-shake motor 10a may include a photosensitive component 1. After the light is emitted from 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 drive the photosensitive component 1 to move relative to the optical element 10b along the first direction X and / or the third direction Y to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.
[0115] Exemplarily, the focusing component 20 may include a lens group 20a and a focusing motor 20b. The lens group 20a may be mounted on the focusing motor 20b. The focusing motor 20b may drive the lens group 20a to move along the optical axis direction (which is also the third direction Y in this embodiment) to achieve auto focus (AF). Among them, 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 jointly constitute the optical system of the camera module 100.
[0116] Figure 5 Yes Figure 3 It is a schematic cross-sectional structure diagram in an embodiment of the first anti-shake component shown in section along B-B. Figure 6 Yes Figure 3 It is a schematic exploded view of the anti-shake motor 10a in some embodiments.
[0117] As Figures 4 to 6 As shown, the anti-shake motor 10a may further include a fixed bracket 2, a movable base 3, a first driving mechanism 4, and a second driving mechanism 5. The fixed bracket 2 may have an installation space 2a for installing the optical element 10b. The movable base 3 may be movably connected to the fixed bracket 2. The first driving mechanism 4 may be used to drive the movable base 3 to move relative to the fixed bracket 2 along the first direction X. The second driving mechanism 5 may be used to drive the movable base 3 to move relative to the fixed bracket 2 along the third direction Y. Among them, the first driving 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 from the photosensitive component 1 in the second direction Z. The projection of the first driving mechanism 4 on the plane where the sensor circuit board 12 is located may cover at least part of the electronic device 13. A part of the second driving mechanism 5 may be mounted on the movable base 3, and the other part may be mounted on the fixed bracket 2.
[0118] Exemplarily, the photosensitive component 1 can be fixed to the movable base 3. Among them, the photosensitive component 1 can include an image sensor 11, a sensor circuit board 12, and electronic devices 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 devices 13 can be fixed to the sensor circuit board 12 and electrically connected to the sensor circuit board 12. The electronic devices 13 and the image sensor 11 can be arranged at intervals in the first direction X. Exemplarily, the electronic devices 13 can 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 (such as for filtering, etc.).
[0119] 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 relative to the fixed bracket 2 along the first direction X and / or the third direction Y, that is, relative to the optical element along the first direction X and / or the third direction Y, so as to achieve optical image stabilization.
[0120] It can be understood that compared with the first coil of the first driving mechanism being fixed to the sensor circuit board, the first coil and the image sensor are arranged in the first direction X, so that the size of the sensor circuit board in the first direction X is relatively large, and the size of the entire image stabilization motor in the first direction X is relatively large, which is not conducive to the miniaturization of the image stabilization motor. In the image stabilization motor 10a of this embodiment, the first coil 41 of the first driving mechanism 4 and the photosensitive component 1 are arranged at intervals in the second direction Z. The projection of the first driving mechanism 4 on the plane where the sensor circuit board 12 is located can cover at least part of the electronic devices 13 of the photosensitive component 1. In this way, the first coil 41 and the sensor circuit board 12 are arranged at intervals in the second direction Z, and the projection of the first coil 41 on the plane where the sensor circuit board 12 is located can cover at least part of the electronic devices 13, so that the size of the sensor circuit board 12 in the first direction X can be effectively reduced, and the size of the entire image stabilization motor 10a in the first direction X can be saved. In other words, the image stabilization motor 10a of this embodiment can realize the miniaturization of the image stabilization motor 10a while driving the photosensitive component 1 to move relatively to achieve optical image stabilization.
[0121] In other embodiments, the positions of the first coil 41 and the first magnetic member 42 can also be interchanged, that is, the first coil 41 can also be fixed to the fixed bracket 2, and the first magnetic member 42 can also be fixed to the movable base 3.
[0122] Next, the specific structure of the image stabilization motor 10a will be introduced in combination with the relevant drawings.
[0123] Figure 7 is Figure 6 The structural schematic diagram of the movable base 3 shown in some embodiments.Figure 8 is Figure 6 A schematic structural view of the movable base 3 shown in another perspective.
[0124] As Figures 6 to 8 shown, 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 respectively 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 inside the base frame portion 32. The base bottom 33 may be provided with a first through hole 331. The first through hole 331 may communicate with the receiving space 3a of the movable base 3. The receiving space 3a may be used to receive a part of the fixing bracket 2 and at least part of the optical element 10b mounted on the fixing bracket 2 (please refer to Figure 5 shown).
[0125] Exemplarily, the base frame portion 32 may include a first side portion 321, a second side portion 322, and a third side portion 323 that are sequentially connected. 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 jointly enclose the inside of the base frame portion 32. Among them, the surface of the first side portion 321 facing away from the second side portion 322 is the first surface 3211. The surface of the first side portion 321 facing away from the third side portion 323 is the second surface 3212. The surface of the third side portion 323 facing away from the second side portion 322 is the third surface 3231. The surface of the third side portion 323 facing away from the first side portion 321 is the fourth surface 3232.
[0126] Exemplarily, the base top 31 may include a first branch portion 311, a second branch portion 312, and a third branch portion 313. The second branch portion 312 may be connected between the first branch portion 311 and the third branch portion 313. The first branch portion 311, the second branch portion 312, and the third branch portion 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-surround the receiving space 3a. The first branch portion 311 may be opposite to and spaced apart from a part of the base bottom 33. The third branch portion 313 may be opposite to and spaced apart from a part of the base bottom 33. It should be understood that Figure 7 and Figure 8 both schematically divide the first branch portion 311, the second branch portion 312, and the third branch portion 313 by dotted lines.
[0127] Exemplarily, the movable base 3 may further have a first avoidance space 3b. The first avoidance space 3b may be located between the first branch portion 311 and the base bottom 33 and outside the base frame portion 32. Both the first surface 3211 and the second surface 3212 of the first side portion 321 may face the first avoidance space 3b. The first avoidance space 3b may communicate with the receiving space 3a of the movable base 3.
[0128] Exemplarily, the movable base 3 may further have a second avoidance space 3c. The second avoidance space 3c may be located between the third branch 313 and the base bottom 33, and outside the base frame portion 32. The third surface 3231 and the fourth surface 3232 of the third side portion 323 may both face the second avoidance space 3c. The second avoidance space 3c may communicate with the accommodation space 3a of the movable base 3.
[0129] Exemplarily, the base bottom 33 is provided with a plurality of movable slots, such as including a first movable slot 332, a second movable slot 333, a third movable slot 334, and a fourth movable slot 335. The four movable slots may be respectively located at the four corners of the movable base 3. The openings of the four movable slots may all face the base top 31. Among them, the first movable slot 332 and the second movable slot 333 may communicate with the first avoidance space 3b. The third movable slot 334 and the fourth movable slot 335 may communicate with the second avoidance space 3c.
[0130] 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 inside of the outer frame portion. The inner frame portion may be fixedly connected to the base top 31 and together with the base top 31 form a first base. The outer frame portion may be fixedly connected to the base bottom 33 and together with the base bottom 33 form a second base. In this way, compared with the movable base being an integrally formed structure, the movable base has more structural features and greater manufacturing difficulty. 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 respectively manufactured and then assembled, which is beneficial to reducing the manufacturing difficulty of the movable base 3 and improving the manufacturing precision of the movable base 3.
[0131] Figure 9 Yes Figure 6 The structural schematic diagram of the first circuit board 61 shown in another perspective.
[0132] As Figure 9As shown, 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-flex 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 respectively located on two opposite sides of the first fixing portion 611 and are 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. Among them, 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 part of the first fixing portion 611. It should be noted that although the first circuit board 61 is described in multiple parts in this embodiment, it does not affect the first circuit board 61 being an integrally formed structure.
[0133] Exemplarily, the first surrounding portion 614 may include a first bending segment 614a, a second bending segment 614b, and a third bending segment 614c connected in sequence. Among them, the end of the first bending segment 614a facing away from the second bending segment 614b may be fixedly connected to the first fixing portion 611 and the second fixing portion 612. The first bending segment 614a may be bent relative to the first fixing portion 611 and the second fixing portion 612 (for example, the plane where the first bending segment 614a is located may form an angle with the plane where the first fixing portion 611 is located). The first bending segment 614a may be located on the same side of the first fixing portion 611 and the second fixing portion 612. The second bending segment 614b may be bent relative to the first bending segment 614a. The second bending segment 614b may be spaced apart from the first fixing portion 611 in the first direction X. The third bending segment 614c may be bent relative to the second bending segment 614b. The third bending segment 614c may be fixedly connected to the third fixing portion 613. The third bending segment 614c may be spaced apart from the first bending segment 614a in the third direction Y. The third bending segment 614c may face the first bending segment 614a. A part of the first fixing portion 611 may be located between the first bending segment 614a and the third bending segment 614c. The third bending segment 614c may be located on the side of the third fixing portion 613 facing the first fixing portion 611 and is bent relative to the third fixing portion 613.
[0134] Figure 10 is Figure 6 Schematic diagram of the assembly structure of the movable base 3 and the first circuit board 61 shown. Figure 11 is Figure 10 Schematic diagram of the structure shown from another perspective.
[0135] AsFigure 10 and Figure 11 As shown in Figure 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 is 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 generally in an "L" shape. The second fixing portion 612 can be located on the periphery 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.
[0136] Exemplarily, the first surrounding portion 614 can be disposed to surround a part of the base top 31 of the movable base 3. Among them, the first bending section 614a can be located on the side of the second branch 312 of the base top 31 facing away from the accommodation space 3a. The first bending section 614a can be spaced from the base frame portion 32 in the third direction Y. The second bending section 614b can be located on the side of the third side portion 323 of the base frame portion 32 facing away from the first side portion 321. That is, the second bending section 614b can be located on the side of the third branch 313 of the base top 31 facing away from the first branch 311. The second bending section 614b can be spaced from the base frame portion 32 in the first direction X. The third bending section 614c can be located on the side of the base frame portion 32 facing away from the first bending section 614a. That is, the third bending section 614c can be located on the side of the first branch 311 of the base top 31 facing away from the third branch 313. The third bending section 614c can be spaced from the base frame portion 32 in the third direction Y.
[0137] Exemplarily, the base bottom 33 can further be provided with a first groove 336. The opening of the first groove 336 can face away from the first through hole 331. The connecting portion of the first bending section 614a of the first surrounding portion 614 and the first fixing portion 611 can be received in the first groove 336. In this way, on the one hand, the first groove 336 can be used to position the first bending section 614a during the assembly of the first circuit board 61, facilitating the 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 relatively compact, which is conducive to realizing the miniaturization of the anti-shake motor 10a.
[0138] Figure 12 is Figure 6 a schematic structural diagram of the second circuit board 62 shown in some embodiments.
[0139] As shown Figure 12 in the figure, the anti-shake motor 10a may further include a second circuit board 62. The second circuit board 62 may be a flexible circuit board or a rigid-flex circuit board.

The fifth bending section 623b may be bent relative to the fourth bending section 623a. The sixth bending section 623c may be bent relative to the fifth bending section 623b. The end of the sixth bending section 623c facing away from the fifth bending section 623b may be connected to the fifth fixing portion 622. The sixth bending section 623c may be bent relative to the fifth fixing portion 622. The sixth bending section 623c may be spaced from the fourth bending section 623a in the third direction Y.

[0141] Figure 13 is Figure 6 a schematic assembly structure diagram of the first circuit board 61, the second circuit board 62, and the movable base 3 as shown. Figure 14 is Figure 4 a partial cross-sectional structure diagram of a certain embodiment of the anti-shake motor 10a cut along C-C as shown. Figure 15 is Figure 13 a schematic structure diagram of the structure shown in another perspective.
[0142] As Figures 13 to 15As shown, the fourth fixing portion 621 can fixedly connect to the surface of the bottom 33 of the connecting base facing away from the top 31 of the base. The fourth fixing portion 621 can be generally in an "L" shape. The fourth fixing portion 621 can be located on the peripheral side of the first through hole 331. The fourth fixing portion 621 and the second fixing portion 612 of the first circuit board 61 can be arranged side by side in the first direction X. The fourth fixing portion 621 and the second fixing portion 612 can have a left-right symmetric structure. The fifth fixing portion 622 can be located on the side of the top 31 of the base facing away from the bottom 33 of the base. The fifth fixing portion 622 and the third fixing portion 613 of the first circuit board 61 can be arranged side by side in the first direction X. The fifth fixing portion 622 and the third fixing portion 613 can have a left-right symmetric structure.
[0143] Exemplarily, the second surrounding portion 623 can surround a part of the movable base 3. Among them, the fourth bending section 623a of the second surrounding portion 623 can be spaced from the top 31 of the base of the movable base 3 in the third direction Y. The fifth bending section 623b of the second surrounding portion 623 can be spaced from the top 31 of the base of the movable base 3 in the first direction X. The fifth bending section 623b of the second surrounding portion 623 can be located on the side of the first branch 311 of the top 31 of the base facing away from the third branch 313. The sixth bending section 623c of the second surrounding portion 623 can be located on the side of the movable base 3 facing away from the fourth bending section 623a of the second surrounding portion 623. The second surrounding portion 623 and the first surrounding portion 614 of the first circuit board 61 can be arranged side by side in the first direction X. The second surrounding portion 623 and the first surrounding portion 614 can have a left-right symmetric structure.
[0144] Exemplarily, the projection of the second fixing portion 612 of the first circuit board 61 on the plane where the top 31 of the base is located can cover a part of the first branch 311 of the top 31 of the base. The projection of the third fixing portion 613 of the first circuit board 61 on the plane where the top 31 of the base is located can cover a part of the third branch 313 of the top 31 of the base. In this way, the distance between the second fixing portion 612 and the third fixing portion 613 of the first circuit board 61 is relatively far, so that the length of the first surrounding portion 614 connected between the second fixing portion 612 and the third fixing portion 613 can be effectively extended, so as to increase the overall length of the first circuit board 61, which is beneficial to reducing the elastic coefficient of the first circuit board 61 itself.
[0145] Exemplarily, the projection of the fourth fixing portion 621 of the second circuit board 62 on the plane where the top 31 of the base is located may cover a part of the third branch 313 of the top 31 of the base. The projection of the fifth fixing portion 622 of the second circuit board 62 on the plane where the top 31 of the base is located may cover a part of the first branch 311 of the top 31 of the base. In this way, the distance between the fourth fixing portion 621 and the fifth fixing portion 622 of the second circuit board 62 is relatively far, so that the length of the second surrounding portion 623 connected between the fourth fixing portion 621 and the fifth fixing portion 622 can be effectively extended, so as to increase the overall length of the second circuit board 62, which is beneficial to reducing the elastic coefficient of the second circuit board 62 itself.
[0146] Exemplarily, the whole of the second fixing portion 612, the third fixing portion 613 and the first surrounding portion 614 of the first circuit board 61 and the whole of the fourth fixing portion 621, the fifth fixing portion 622 and the second surrounding portion 623 of the second circuit board 62 may be substantially symmetric about the left and right. The length of the first surrounding portion 614 may be equal to the length of the second surrounding portion 623. Among them, the equality of the lengths of the first surrounding portion 614 and the second surrounding portion 623 may be exactly 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 may be less than or equal to 0.01 times the length of the first surrounding portion 614.
[0147] Exemplarily, a part of the first bending section 614a of the first circuit board 61 may be opposite to the fourth bending section 623a of the second circuit board 62. In other words, the projection of the first bending section 614a of the first circuit board 61 on the plane where the fourth bending section 623a is located may cover a part of the fourth bending section 623a of the second circuit board 62. In this way, the first bending section 614a and the fourth bending section 623a have an overlapping part, so that the lengths of the first circuit board 61 and the second circuit board 62 can be extended, which is beneficial to reducing the elastic coefficients of the first circuit board 61 and the second circuit board 62 themselves, beneficial to reducing the driving force required for the moving base 3 to move relative to the fixed bracket 2, and beneficial to reducing the power consumption when the anti-shake motor 10a performs optical anti-shake.
[0148] Please refer to again Figures 13 to 15 , a second groove 337 may also be provided on the bottom 33 of the base ( Figure 11Also shows the second groove 337 from another perspective. The opening of the second groove 337 can face away from the first through hole 331. The second groove 337 can be arranged at an interval from the first groove 336. The joint part of the fourth bending section 623a of the second surrounding part 623 and the fourth fixing part 621 can be received 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 part 623 when assembling the second circuit board 62, so as to facilitate the assembly; on the other hand, the second surrounding part 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 beneficial to realizing miniaturization.
[0149] Exemplarily, 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 bending section 614a of the first circuit board 61 can be arranged relatively close to the base top 31 and the base frame part 32 compared with the fourth bending section 623a of the second circuit board 62. In this way, the first bending section 614a of the first circuit board 61 can be arranged at an interval from the fourth bending section 623a of the second circuit board 62 in the third direction Y while facing the fourth bending section 623a of a part of the second circuit board 62, so as to effectively avoid collision and mutual interference between the two, which may affect the normal operation of the anti-shake motor 10a.

Figure 17 is Figure 16 A schematic diagram of the structure shown from another perspective. Figure 18 is Figure 4 A partial cross-sectional structure schematic diagram of a specific embodiment of the anti-shake motor 10a shown cut along D-D. For the convenience of understanding, Figure 17 the first circuit board 61, the second circuit board 62 and the dielectric layer board 63 of the anti-shake motor 10a are hidden in the figure.

The shape of the dielectric layer board 63 can be substantially the same as the shape of the first fixing part 611. Among them, the first coil 41, the second coil 51 and the dielectric layer board 63 can be integrally formed. For example, the metal part in the insulating plate can be etched into a coil by means of etching and the like. In this way, by means of etching and the like, the patterned first coil 41 and second coil 51 are formed on the insulating plate with a metal part, which is beneficial to improving the preparation precision of the first coil 41 and the second coil 51, ensuring the flatness of the surface of the first coil 41 and the surface of the second coil 51, and ensuring the thickness consistency of the first coil 41 and the second coil 51.

[0155] Exemplarily, the anti-shake motor 10a may further include a plurality of balls 8. For example, the number of balls 8 may be four. The shape and size of each ball 8 may be exactly the same. Therefore, each ball 8 may be labeled with the same number.

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 may be equal to the distance between the two first coils 41. Exemplarily, the first position sensor 71 may face the first coil 41. The third position sensor 73 may face the third coil 43. In this way, the distance between the first position sensor 71 and the third position sensor 73 is larger, so that the magnetic field ranges that the first position sensor 71 and the third position sensor 73 can detect are larger, which is beneficial to improving the movement accuracy of the anti-shake motor 10a.

At least part of the other first magnetic member 42 can be located in the third sub-gap 2133 and be spaced from the second portion 232 of the bottom of the bracket 23.
[0173] Exemplarily, the first magnetic member 42 can include two first magnets 421 and one first magnetic conductive plate 422. The two first magnets 421 can be respectively located on opposite sides of the first magnetic conductive plate 422. The two first magnets 421 can be fixedly connected to the first magnetic conductive plate 422. The two first magnets 421 can be spaced in the first direction X. It should be understood that the arrangement of the first magnetic member 42 is relatively diverse, and the present embodiment does not specifically limit the arrangement method of the first magnetic member 42.
[0174] Exemplarily, the second driving mechanism 5 (please refer to Figure 6 as shown) can also include a second magnetic member 52. The second magnetic member 52 can be generally strip-shaped. The second magnetic member 52 can be located on the side of the plate body portion 212 of the top of the bracket 21 facing the bottom of the bracket 23, and fixedly connect to the plate body portion 212. At this time, at least part of the second magnetic member 52 can be located in the second sub-gap 2132 between the mounting portion 22 and the top of the bracket 21. Part of the second magnetic member 52 and part of the mounting portion 22 can be stacked in the second direction Z. Among them, the second magnetic member 52 can include two second magnets 521 and one second magnetic conductive plate 522. The two second magnets 521 can be respectively located on opposite sides of the second magnetic conductive plate 522. The two second magnets 521 can be fixedly connected to the second magnetic conductive plate 522. The two second magnets 521 can be spaced in the third direction Y. It should be understood that the arrangement of the second magnetic member 52 is relatively diverse, and the present embodiment does not specifically limit the arrangement method of the second magnetic member 52.
[0175] Figure 29 is Figure 6 a partial structural assembly diagram of the anti-shake motor 10a as shown. Figure 30 is Figure 4 a partial cross-sectional structural diagram of a certain embodiment of the anti-shake motor 10a cut along the E-E as shown. Figure 31 is Figure 4Schematic diagram of a partial cross-sectional structure in an embodiment of the anti-shake motor 10a shown in a cross-section along F-F.
[0176] As Figures 29 to 31 shown, the base bottom 33 of the movable base 3 can be movably connected to the base bottom 23 of the fixed bracket 2 through the balls 8. Exemplarily, the openings of the four movable grooves of the base bottom 33 can be oppositely arranged corresponding to the openings of the four movable grooves of the base bottom 23 of the bracket. Among them, the first movable groove 332 and the fifth movable groove 2311 can jointly form the first ball groove 81. The second movable groove 333 and the sixth movable groove 2312 can jointly form the second ball groove 82. The third movable groove 334 and the seventh movable groove 2321 can jointly form the third ball groove 83. The fourth movable groove 335 and the eighth movable groove 2322 can jointly form the fourth ball groove 84. The balls 8 between the base bottom 33 and the base bottom 23 of the bracket can not only roll along the first direction X in the ball groove, but also roll along the third direction Y in the ball groove. In other words, the movable base 3 can move relative to the fixed bracket 2 along the first direction X, and can also move relative to the fixed bracket 2 along the third direction Y. It can be understood that only one layer of balls 8 is provided between the movable base 3 and the fixed bracket 2 in this embodiment, and the movable base 3 can be moved relative to the fixed bracket 2 in multiple directions, and it is not easy to get stuck when the movable base 3 moves relative to the fixed bracket 2.
[0177] In some embodiments, the anti-shake motor 10a may further include a magnetic attraction sheet 101 and a magnet 102. The magnetic attraction sheet 101 can be embedded in the base bottom 33 of the movable base 3. The magnet 102 can be embedded in the base bottom 23 of the fixed bracket 2. The projection of the magnet 102 along the second direction Z can cover at least a part of the magnetic attraction sheet 101. In this way, the magnetic attraction sheet 101 and the magnet 102 can cooperate to generate a force. The movable base 3 can squeeze the fixed bracket 2 under the action of the force between the magnetic attraction sheet 101 and the magnet 102, so as to avoid the tilting of the movable base 3 relative to the fixed bracket 2 during the movement in the X-Y plane, which is beneficial to improving the movement smoothness of the movable base 3 relative to the fixed bracket 2 during the movement. In other embodiments, the positions of the magnetic attraction sheet 101 and the magnet 102 can also be interchanged, that is, the magnetic attraction sheet 101 can be embedded in the base bottom 23 of the bracket, and the magnet 102 can be embedded in the base bottom 33 of the movable base. The specific positions of the magnetic attraction sheet 101 and the magnet 102 are not limited in this embodiment.
[0178] Figure 32 is Figure 4 Schematic diagram of a partial cross-sectional structure in an embodiment of the structure shown in a cross-section along C-C. Figure 33 is Figure 4 Schematic diagram of a partial cross-sectional structure in an embodiment of the structure shown in a cross-section along D-D.
[0179] AsFigure 29 , Figure 32 and Figure 33 As shown, the first through hole 331 of the movable base 3 can communicate with the installation space 2a of the fixed bracket 2 and is disposed opposite to the installation space 2a. That is, the photosensitive component 1 can be disposed opposite to the installation space 2a. The image sensor 11 can be disposed facing the installation space 2a. The top 31 of the base of the movable base 3 can be located between the top 21 and the bottom 23 of the bracket of the fixed bracket 2. The bottom 23 of the bracket of the fixed bracket 2 can be located between the top 31 and the bottom 33 of the base of the movable base 3. At least a part of the installation portion 22 of the fixed bracket 2 can be located in the receiving space 3a of the movable base 3.
[0180] Exemplarily, the first part 231 of the bottom 23 of the bracket can be located in the first avoidance space 3b between the first branch 311 of the top 31 of the base and the bottom 33 of the base and is movably connected to the bottom 33 of the base. The second part 232 of the bottom 23 of the bracket can be located in the second avoidance space 3c between the third branch 313 of the top 31 of the base and the bottom 33 of the base and is movably connected to the bottom 33 of the base. The first branch 311 of the top 31 of the base can be located between the second side 2112 of the top 21 of the bracket and the first part 231 of the bottom 23 of the bracket, that is, in the third avoidance space 2b of the fixed bracket 2. The third branch 313 of the top 31 of the base can be located between the fourth side 2114 of the top 21 of the bracket and the second part 232 of the bottom 23 of the bracket, that is, in the third avoidance space 2b of the fixed bracket 2. At this time, the top 21 of the bracket, the top 31 of the base, the bottom 23 of the bracket, and the bottom 33 of the base can be stacked in sequence in the second direction Z.
[0181] Exemplarily, the second branch 312 of the top 31 of the base can be located on the side of the top 21 of the bracket facing the bottom 23 of the bracket. The second branch 312 can be stacked with the installation portion 22 in the second direction Z. The second driving mechanism 5 can be stacked with the installation portion 22 in the second direction Z.
[0182] Figure 34 is Figure 4 A partial cross-sectional structural schematic diagram of a part of an embodiment in which the anti-shake motor 10a shown is cut along G-G. Figure 35 is Figure 4 A partial cross-sectional structural schematic diagram of a part of an embodiment in which the anti-shake motor shown is cut along H-H.
[0183] As Figures 32 to 35 shown, the installation portion 22 and the bottom 23 of the bracket of the fixed bracket 2 can semi-surround the base frame portion 32 of the movable base 3. The top 31 of the base of the movable base 3 can semi-surround the receiving space 3a. The top 31 of the base of the movable base 3 can semi-surround the installation portion 22 of the fixed bracket 2.
[0184] It can be understood that, compared with a general anti-shake motor in which the entire movable base is located inside the fixed bracket or the entire fixed bracket is located inside the movable base, the overall size of the anti-shake motor in the first direction X and the third direction Y is relatively large, which is not conducive to the miniaturization of the anti-shake motor. In the anti-shake motor 10a of the present embodiment, by arranging that a part of the movable base 3 can semi-surround the fixed bracket 2 and a part of the fixed bracket 2 can semi-surround the movable base 3, the movable base 3 and the fixed bracket 2 can utilize the size spaces of each other in the first direction X and the third direction Y, so that the overall structure of the movable base 3 and the fixed bracket 2 is relatively compact, which is conducive to saving the size of the anti-shake motor 10a in the first direction X and the third direction Y and is conducive to realizing the miniaturization of the anti-shake motor 10a.
[0185] Secondly, compared with a general anti-shake motor in which the movable base and the fixed bracket are stacked in the second direction Z, the overall thickness of the anti-shake motor is relatively thick, which is not conducive to the thin-type setting of the anti-shake motor. In the present embodiment, by arranging that the base bottom 33 and the base top 31 of the movable base 3 and the bracket bottom 23 and the bracket top 21 of the fixed bracket 2 are alternately stacked in the second direction Z, the movable base 3 and the fixed bracket 2 can be mutually embedded to utilize the size spaces of each other in the second direction Z, so that the overall structure of the movable base 3 and the fixed bracket 2 is relatively compact, which is conducive to saving the size of the anti-shake motor 10a in the second direction Z and is conducive to realizing the miniaturization of the anti-shake motor 10a.
[0186] Please refer to again Figure 29 、 Figure 32 and Figure 33As shown, the third fixing portion 613 of the first circuit board 61 can be fixed to the surface of the plate body portion 212 of the top of the bracket 21 facing away from the bottom of the bracket 23. At this time, the first bending section 614a of the first circuit board 61 can be located between the third side portion 2113 of the frame portion 211 of the top of the bracket 21 and the bottom 33 of the base. The second bending section 614b of the first circuit board 61 can be located between the fourth side portion 2114 of the frame portion 211 and the bottom 33 of the base. The third bending 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 top 31 of the base of the movable base 3 and is connected to the outer side surface of the support portion 24. In this way, in addition to realizing the transmission of electrical signals, the first circuit board 61 can also 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, so that the difference values of the entire anti-shake motor 10a in different postures are relatively small, which is beneficial to ensuring the stability of the anti-shake performance of the image sensor 11 in different postures during the movement of the anti-shake motor 10a and improving the anti-shake accuracy of the anti-shake motor 10a. At the same time, the first circuit board 61 can be bent multiple times to surround part of the movable base 3, so that the overall length of the first circuit board 61 is relatively long, so as to reduce the elastic coefficient of the first circuit board 61 itself, which is beneficial to reducing the driving force required for the movable base 3 to move relative to the fixed bracket 2 and is beneficial to reducing the power consumption of the anti-shake motor 10a during optical anti-shake.
[0187] Exemplarily, the fifth fixing portion 622 of the second circuit board 62 can be fixed to the surface of the plate body portion 212 of the top of the bracket 21 facing away from the bottom of the bracket 23. At this time, the fourth bending section 623a of the second circuit board 62 can be located between the third side portion 2113 of the frame portion 211 and the bottom 33 of the base. The fifth bending section 623b of the second circuit board 62 can be located between the second side portion 2112 of the frame portion 211 and the bottom 33 of the base. The sixth bending section 623c of the second circuit board 62 can be located on the side of the support portion 24 of the fixed bracket 2 facing away from the top 31 of the base of the movable base 3 and is 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 bending section 623c of the second circuit board 62 and the third bending section 614c of the first circuit board 61. In this way, in addition to realizing the transmission of electrical signals, the second circuit board 62 can also 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 to improve the movement accuracy of the movable base 3 and improve the anti-shake accuracy of the anti-shake motor 10a. At the same time, the second circuit board 62 can be bent multiple times to surround part of the movable base 3, so that the overall length of the second circuit board 62 is relatively long, so as to reduce the elastic coefficient of the second circuit board 62 itself, which is beneficial to reducing the driving force required for the movable base 3 to move relative to the fixed bracket 2 and is beneficial to reducing the power consumption of the anti-shake motor 10a during optical anti-shake.
[0188] It can be understood that the first surrounding portion 614 of the first circuit board 61 and the second surrounding portion 623 of the second circuit board 62 in this embodiment can be of a symmetrical structure (please refer to Figure 6 as shown). 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 can generate forces that are equal in magnitude and opposite in direction due to resistance to deformation, so as to cancel each other out, thereby reducing the influence of the first circuit board 61 and the second circuit board 62 on the movement accuracy of the movable base 3 and improving the anti-shake accuracy of the anti-shake motor 10a.
[0189] In some embodiments, the plate body portion 212 and the support portion 24 can also be provided with limit posts 25. The third fixing portion 613 and the third bending section 614c of the first circuit board 61 can also be provided with limit holes 615. In this way, through the cooperation of the limit posts 25 and the limit holes 615, it is convenient for positioning during the assembly of the first circuit board 61 and the fixed bracket 2, thereby improving the assembly efficiency.
[0190] In some embodiments, the first circuit board 61 and the second circuit board 62 can also be of an integrally formed structure, that is, the first circuit board 61 and the second circuit board 62 can be the same circuit board. For example, the second fixing portion 612 of the first circuit board 61 and the fourth fixing portion 621 of the second circuit board 62 can be integrally formed.
[0191] Figure 36 Yes Figure 32 It 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 another perspective.
[0192] Such as Figure 32 、 Figure 33 and Figure 36As shown, the first magnetic member 42 can be disposed opposite to 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 to drive the photosensitive component 1 to move relative to the fixed bracket 2 along 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 along the first direction X. The first position sensor 71 and the third position sensor 73 can both be disposed opposite to the first magnetic member 42. The first position sensor 71 and the third position sensor 73 can both be used to detect the magnetic field strength of the first magnetic member 42 in different positions to detect the position of the movable base 3. Among them, the driving force generated by the cooperation of the first coil 41 and the first magnetic member 42 is the first driving force. The driving force generated by the cooperation of the third coil 43 and the first magnetic member 42 is the second driving force. The directions of the first driving force and the second driving force can both be parallel to the first direction X.
[0193] Exemplarily, the projection of the geometric center of the rectangle formed by the center connection lines of 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, various combined motion modes of the movable base 3 moving and rotating relative to the fixed bracket 2 in different directions can be correspondingly realized. In other words, through the cooperation of the first driving force and the second driving force, the movable base 3 can be driven to move relative to the fixed bracket 2 along the first direction X, and / or the movable base 3 can be driven to rotate relative to the fixed bracket 2 around the first axis R. That is, the first driving mechanism 4 can drive the movable base 3 to drive the photosensitive component 1 to move relative to the fixed bracket 2 along the first direction X and / or rotate around the first axis R.
[0194] In one embodiment, different-direction electrical signals can be input to the third coil 43 and the first coil 41 simultaneously (that is, the current direction of the third coil 43 is opposite to that of the first coil 41), and the magnitudes of the currents input to the third coil 43 and the first coil 41 are different. At this time, the magnitudes of the first driving force and the second driving force are different, and the directions are opposite. The magnitudes of the first driving torque and the second driving torque are different, but the directions are the same. At this time, the movable base 3 can move relative to the fixed bracket 2 along the first direction X under the combined action of the first driving force and the second driving force. Among them, 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 about the first axis R under the combined action of the first driving torque and the second driving torque. Among them, the direction of rotation of the movable base 3 is the direction of the first driving torque and the second driving torque.
[0195] In one embodiment, the third coil 43 and the first coil 41 are also input with electrical signals in the same direction simultaneously (that is, the current direction of the third coil 43 is the same as that of the first coil 41), and the magnitudes of the currents input to the third coil 43 and the first coil 41 are different. At this time, the magnitudes of the first driving force and the second driving force are different, but the directions are the same. The magnitudes of the first driving torque and the second driving torque are different, but the directions are opposite. At this time, the movable base 3 can move relative to the fixed bracket 2 along the first direction X under the combined action of the first driving force and the second driving force. Among them, the direction of movement of the movable base 3 is the direction of the first driving force and the second driving force. The movable base 3 can also rotate relative to the fixed bracket 2 about the first axis R under the combined action of the first driving torque and the second driving torque. Among them, when the first driving torque is greater than the second driving torque, the movable base 3 can rotate relative to the fixed bracket 2 about the first axis R in the direction of the first driving torque. Conversely, the movable base 3 can rotate relative to the fixed bracket 2 about the first axis R in the direction of the second driving torque.
[0196] Such as Figure 32 、 Figure 33 And Figure 36As shown, the second magnetic member 52 can be disposed 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 relative to the fixed bracket 2 along the third direction Y. That is, the second driving mechanism 5 can drive the movable base 3 to drive the photosensitive component 1 to move relative to the fixed bracket 2 along the third direction Y. The second position sensor 72 can be disposed 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.
[0197] Exemplarily, the geometric center of the rectangle formed by the central connection lines 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 relatively high, which is beneficial to improving the imaging quality of the camera module.
[0198] It can be understood that the movable base 3 in this embodiment can drive the image sensor 11 to move relative to the fixed bracket 2 along the first direction X and the third direction Y to achieve anti-shake of the anti-shake motor 10a in the first direction X and the third direction Y. On this basis, a third coil 43 is also provided in the anti-shake motor 10a in this embodiment to cooperate with the first magnetic member 42 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 41 and the first magnetic member 42. In this way, the movable base 3 can also drive the photosensitive component 1 to rotate relative to the fixed bracket 2 around the first axis R under the combined action of the first driving force and the second driving force, so as to compensate for the jitter generated when the electronic device 1000 rotates around the axis parallel to the second direction Z, so that the anti-shake motor 10a can achieve three-axis anti-shake. The anti-shake motor 10a can cover more anti-shake scenarios, which is beneficial to improving the imaging quality and enhancing the user experience.
[0199] In other embodiments, the first magnetic member 42 can further include a first sub-magnetic member and a second sub-magnetic member that are spaced apart. The first sub-magnetic member and the second sub-magnetic member can be respectively disposed opposite to the first coil 41 and the third coil 43.
[0200] In some other embodiments, the winding plane of the first coil 41 can also be perpendicular to the plane where the first direction X and the third direction Y are located. At this time, the first magnetic member 42 and the first coil 41 can also be spaced apart in the first direction X.
[0201] Figure 37 is Figure 4 A schematic cross-sectional structure diagram of an embodiment in which the anti-shake motor 10a shown is cut along C-C. Figure 38 is Figure 4Schematic cross-sectional structure diagram of an implementation mode in which the anti-shake motor 10a shown is cut along D-D.
[0202] As Figure 37 and Figure 38 shown, the anti-shake motor 10a may further include a housing 103. The movable base 3 and at least part of the fixed bracket 2 may be installed in the internal space 103a of the housing 103. Among them, the housing 103 may include a frame body 1031 and a bottom plate 1032. The bottom plate 1032 may be fixedly connected to the frame body 1031 and enclose the internal space 103a of the housing 103 with the frame body 1031. The bracket top 21 of the fixed bracket 2 may be fixedly connected to the frame body 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. Both the movable base 3 and the photosensitive component 1 may be located in the internal space 103a of the housing 103. The movable base 3 may be arranged at an interval from the bottom plate 1032 of the housing 103. The photosensitive component 1 may be arranged at an interval 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 may be located outside the housing 103. The third fixing portion 613 and the fifth fixing portion 622 may be used for electrical connection to other devices (such as a power supply, a driving chip, etc.) outside the anti-shake motor 10a. The second connecting portion 93 of the elastic member 9 may be fixedly connected to the housing 103 (please refer to Figure 22 shown). In this way, when the movable base 3 drives the photosensitive component 1 to move relative to the fixed bracket 2 together, the elastic member 9 may 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 improving the movement accuracy of the movable base 3 and the anti-shake accuracy of the anti-shake motor 10a.
[0203] It can be understood that in this implementation mode, the anti-shake motor 10a arranges the first coil 41 of the first driving mechanism 4 and the photosensitive component 1 at intervals in the second direction Z. The first driving mechanism 4 may be located on the side of the photosensitive component 1 facing the installation space 2a. At the same time, the projection of the first driving mechanism 4 on the plane where the sensor circuit board 12 is located may cover part of the sensor circuit board 12. In this way, on the one hand, the first coil 41 and the sensor circuit board 12 are arranged at intervals in the second direction Z, so that the length and / or width dimension of the sensor circuit board 12 can be smaller, thereby effectively reducing the length and / or width dimensions of the movable base 3 and the fixed bracket 2, saving the length and / or width dimensions of the entire anti-shake motor 10a, and being beneficial to realizing the miniaturization setting of the anti-shake motor 10a. On the other hand, the first coil 41 may be located on the side of the photosensitive component 1 facing the installation space 2a, so that the first driving mechanism 4 can also utilize the dimensional space of the optical element 10b in the second direction Z, which is beneficial to realizing the miniaturization setting of the anti-shake motor 10a.
[0204] Secondly, the projection of the first driving mechanism 4 on the plane where the sensor circuit board 12 is located can also cover at least part of the electronic devices 13 provided on the sensor circuit board 12. In this way, the first driving mechanism 4 can also utilize the length and / or width dimension space of the electronic devices 13, so as to effectively reduce the length and / or width dimensions of the sensor circuit board 12, as well as reduce the length and / or width dimensions of the movable base 3 and the fixed bracket 2, so as to save the length and / or width dimensions of the entire anti-shake motor 10a, which is beneficial to realizing the miniaturized setting of the anti-shake motor 10a. At the same time, compared with the anti-shake motor in which the first coil is provided on the sensor circuit board and the electronic device is located in the coil hole of the first coil, there is still part of the first coil between the electronic device and the image sensor, so that the distance between the electronic device and the image sensor is relatively far, and the overall size of the sensor circuit board is large, which is not conducive to the miniaturized setting of the anti-shake motor. In the present embodiment, the first coil 41 and the photosensitive component 1 are arranged in the second direction Z, so that the electronic device 13 can be arranged as close as possible to the image sensor 11, which is beneficial to reducing the size of the sensor circuit board 12, and thus is beneficial to realizing the miniaturized setting of the anti-shake motor 10a.
[0205] Secondly, in the present embodiment, the second coil 51 and the photosensitive component 1 can be arranged at intervals in the second direction Z, and at the same time, part of the second driving mechanism 5 and part 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 size space of the mounting space 2a in the third direction Y, so that the movable base 3 can utilize the size space of the fixed bracket 2 in the third direction Y, making the arrangement of the movable base 3 and the fixed bracket 2 relatively compact in the third direction Y, which is beneficial to saving the size of the entire anti-shake motor 10a in the third direction Y and is beneficial to realizing the miniaturized setting of the anti-shake motor 10a.
[0206] In addition, at least part of the first driving mechanism 4 and at least part of the second driving mechanism 5 in the present embodiment can be located on the periphery of the mounting space 2a. In this way, the first driving mechanism 4 and the second driving mechanism 5 can utilize the size space of the mounting space 2a in the second direction Z, making the overall structural arrangement of the anti-shake motor 10a relatively compact in the second direction Z, which is beneficial to saving the size of the entire anti-shake motor 10a in the second direction Z and is beneficial to realizing the miniaturized setting of the anti-shake motor 10a.
[0207] In addition, the anti-shake motor 10a in this embodiment may further include a dielectric layer board 63. The number of the first coils 41 may be multiple. The multiple first coils 41 may all be embedded in the dielectric layer board 63, and the first coils 41 and the dielectric layer board 63 may be integrally formed, so as to ensure 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, making the magnitude of the force generated between each first coil 41 and the first magnetic member 42 the same, so as to avoid affecting the motion accuracy of the movable base 3 due to uneven force.
[0208] Figure 39 Yes Figure 2 Partial structural schematic diagram of the camera module 100 shown in some embodiments. Figure 40 Yes Figure 39 Schematic diagram of signal transmission between the first driving chip 1002 and the second driving chip 1003 shown. Figure 41 Yes Figure 39 Schematic diagram of signal transmission between the first driving chip 1002 and the second driving chip 1003 in another embodiment shown.
[0209] In some embodiments, as Figures 39 to 41 shown, the camera module 100 may further include a driving motor 30a. The optical folding element 30b may be mounted on the driving motor 30a. The driving motor 30a may be used to drive the optical folding element 30b to rotate in different directions (for example, rotate around the X-axis direction and / or rotate around the Y-axis direction) to achieve optical anti-shake of the camera module 100. At this time, the optical folding element 30b and the driving motor 30a may jointly form 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 jointly achieve optical anti-shake, it is beneficial to increase 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 may also drive the photosensitive component 1 to rotate relative to the fixed bracket 2 around the first axis R (please refer to Figure 36 shown), so that the camera module 100 can jointly achieve optical anti-shake 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 when the second anti-shake component 30 drives the optical folding element 30b to rotate, which is beneficial to improving the imaging quality and enhancing the user experience. At the same time, the movable base 3 of the anti-shake motor 10a driving the photosensitive component 1 to rotate relative to the fixed bracket 2 around the first axis R can also compensate for the jitter generated when the electronic device 1000 rotates around the axis parallel to the second direction Z, so that the anti-shake motor 10a can achieve three-axis anti-shake, and the anti-shake motor 10a can cover more anti-shake scenarios, which is beneficial to improving the imaging quality and enhancing the user experience.
[0210] Exemplarily, the camera module 100 may further include a main circuit board 1001, a first driving chip 1002, and a second driving 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 that are electrically connected to the anti-shake motor 10a), the driving motor 30a, and an external power supply. Both the first driving chip 1002 and the second driving chip 1003 may be fixed to the main circuit board 1001 and are both electrically connected to the main circuit board 1001. Among them, the first driving chip 1002 may be used to control the anti-shake motor 10a of the first anti-shake assembly 10. The second driving chip 1003 may be used to control the driving motor 30a of the second anti-shake assembly 30.
[0211] Exemplarily, the electronic device 1000 further includes a gyroscope. The gyroscope may be electrically connected to both the first driving chip 1002 and the second driving chip 1003 at the same time. The gyroscope may transmit signals to both the first driving chip 1002 and the second driving chip 1003 at the same time. Exemplarily, when the electronic device 1000 shakes, the gyroscope may acquire the attitude information of the electronic device 1000 at this time. The gyroscope may split the attitude information into first position information and second position information through a filtering algorithm, and transmit the first position information to the first driving chip 1002, and transmit the second position information to the second driving chip 1003. After acquiring the first position information, the first driving chip 1002 may control the anti-shake motor 10a of the first anti-shake assembly 10 to drive the optical element 10b to a first target position, realizing the optical anti-shake of the first anti-shake assembly 10. After acquiring the second position information, the second driving chip 1003 may control the driving motor 30a of the second anti-shake assembly 30 to drive the optical folding element 30b to a second target position according to the acquired second position information, realizing the optical anti-shake of the second anti-shake assembly 30. Among them, the first anti-shake assembly 10 may achieve high-frequency and small-angle anti-shake. The second anti-shake assembly 30 may achieve low-frequency and large-angle anti-shake.
[0212] It can be understood that in this embodiment, by setting the gyroscope to acquire the attitude information of the electronic device 1000 and splitting it into first position information and second position information, the first driving chip 1002 and the second driving 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 make full use of the anti-shake performance of the two anti-shake assemblies, improve the anti-shake efficiency, and enhance the user experience.
[0213] In some other embodiments, such as Figure 41As shown, the gyroscope can also be electrically connected to only the first driving chip 1002. The first driving chip 1002 is electrically connected to the second driving chip 1003. When the electronic device 1000 shakes, the gyroscope can obtain the attitude information of the electronic device 1000 at this time. The gyroscope can directly transmit the attitude information to the first driving chip 1002. After obtaining the attitude information of the gyroscope, the first driving chip 1002 can split the attitude information into first position information and second position information through a filtering algorithm. The first driving chip 1002 can control the anti-shake motor 10a of the first anti-shake component 10 to drive the optical element 10b to reach the first target position according to the first position information, so as to realize the optical anti-shake of the first anti-shake component 10. The first driving chip 1002 can also transmit the second position information to the second driving chip 1003. The second driving chip 1003 can control the driving motor 30a of the second anti-shake component 30 to drive the optical folding element 30b to reach the second target position according to the obtained second position information, so as to realize the optical anti-shake of the second anti-shake component 30.
