Description

Technical Field

[0001] This application relates to the field of image acquisition technology, and in particular to a camera driver component, a camera module, and an electronic device. Background Technology

[0002] As users' shooting requirements continue to increase, camera modules typically integrate image stabilization drivers to drive lens movement and compensate for shake generated during shooting, achieving optical image stabilization (OIS) to ensure the clarity of the camera module's images.

[0003] However, the camera modules in related technologies have low control precision and high control difficulty in the image stabilization process, which affects the shooting quality of the camera modules. Summary of the Invention

[0004] This application provides a camera driver component, a camera module, and an electronic device, which can reduce the control difficulty of the image stabilization process and improve the control accuracy of the image stabilization process.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a camera driving assembly, including a base, a first seat body, a second seat body, a carrier, a first actuation component, and a second actuation component. The first seat body is disposed on the base; the second seat body is disposed on the first seat body, and at least a portion of the second seat body is located on the side of the first seat body facing away from the base; the carrier has a lens mounting hole and is disposed on the second seat body; the first actuation component is used to drive the first seat body to move relative to the base along a first direction, a portion of the first actuation component is connected to the first seat body, and another portion is fixed relative to the base; the second actuation component is used to drive the second seat body to move relative to the first seat body along a second direction, a portion of the second actuation component is connected to the second seat body, and another portion is fixed relative to the base; wherein, both the first and second directions are perpendicular to the axial direction of the lens mounting hole, and the first direction is perpendicular to the second direction. The axial direction of the lens mounting hole is the same as the optical axis direction of the lens.

[0007] The camera driving component in this application can control the first base to move along a first direction via a first actuation component, thereby moving the lens in the first direction. It can also control the second base to move along a second direction via a second actuation component, thereby moving the lens in the second direction, and thus achieving translation of the lens in the XY plane. Since the first and second bases are driven by two different sets of actuation components, and their movements in the XY plane are independent, the control programs and algorithms for the lens in the first and second directions can be independent and unaffected, achieving decoupling.

[0008] This approach offers several advantages. First, it simplifies the control procedures and algorithms of optical image stabilization (OIS), reducing its complexity and thus shortening response time and improving efficiency. Second, it enhances control precision, leading to more accurate image compensation from the camera module and improved image quality. Third, when the lens only needs to move along the first direction, the second actuator doesn't need to operate; similarly, when the lens only needs to move along the second direction, the first actuator doesn't need to operate, reducing power consumption of the camera drive components, extending battery life, and avoiding signal interference between the two actuators. Fourth, when the second actuator drives the second mount along the second direction, it doesn't need to drive the first mount, reducing the load on the second actuator and further reducing power consumption of the camera drive components, while also improving control precision.

[0009] In one possible implementation of the first aspect, the first actuation component includes two first actuation units, which are arranged opposite to and spaced apart in a second direction. Each first actuation unit includes a first fixing member, a second fixing member, and a first actuation wire. The first fixing member is fixed relative to the base; the second fixing member is fixedly connected to the first base body, and the second fixing member and the first fixing member are arranged at a distance in the first direction; the first actuation wire is a shape memory alloy wire, which is connected to the first fixing member and the second fixing member. Using a shape memory alloy wire as the first actuation wire of the first actuation component can effectively increase the driving force of the first actuation component and reduce its volume, thereby effectively compressing the overall volume of the entire camera driving component and realizing the miniaturization design of the camera module.

[0010] In one possible implementation of the first aspect, both first actuation units are located circumferentially outside the first base. Since the image sensor in the camera module is typically located on the side of the base facing away from the first base, by placing the first actuation units circumferentially outside the first base, the position of the first actuation line relative to the image sensor can be raised. This increases the vertical distance between the first actuation line and the image sensor along the optical axis, which helps reduce interference from the drive signal in the first actuation line to the image sensor, thereby improving the image clarity of the image sensor and enhancing the shooting performance of the camera module. Furthermore, it fully utilizes the space on the side of the first base, reducing the superimposed dimensions of the first actuation unit, the base, and the first base along the optical axis of the lens. This reduces the height of the camera drive assembly, thereby reducing the thickness of the camera module and the electronic device, facilitating a thinner design for the electronic device.

[0011] In one possible implementation of the first aspect, the first seat includes a first side plate and a second side plate disposed opposite to each other in a second direction, both the first side plate and the second side plate being located circumferentially outside the carrier; one of the two first actuation units is located on the side of the first side plate opposite to the second side plate, and the other first actuation unit is located on the side of the first side plate opposite to the second side plate. A specific arrangement of the first actuation units is provided.

[0012] In one possible implementation of the first aspect, the surface of the first side plate facing away from the second side plate includes a first fixed area and a first clearance area. The first clearance area is recessed relative to the first fixed area toward the carrier. A first fixing member of the first actuation unit is fixedly connected to the first fixed area. In the second direction, the first actuation line is opposite to and spaced apart from the first clearance area. This avoids friction between the first actuation line and the first side plate during contraction or extension, thereby reducing energy loss and improving the accuracy of the anti-shake compensation motion stroke, achieving precise anti-shake.

[0013] In one possible implementation of the first aspect, the first actuation line includes a first end and a second end, the first end being connected to a first fixing member and the second end being connected to a second fixing member; when the first actuation line is not energized, the vertical distance between the first end and the reference plane is less than or equal to the vertical distance between the second end and the reference plane; wherein the reference plane is perpendicular to the axial direction of the lens mounting hole and the reference plane is located on the side of the first actuation line closer to the base.

[0014] In this way, on the one hand, the first actuation line can apply a force along the first direction to the first base, causing the first base and the carrier supporting the lens to move along the first direction, thus achieving optical image stabilization. On the other hand, it can reduce the space occupied by the first actuation unit in the Z-axis direction, which is beneficial to reducing the height of the camera drive assembly and the camera module. This helps to reduce the thickness of the electronic device when the camera drive assembly is applied to the electronic device, enabling a thinner and lighter design. In addition, since the connection between the first and second ends of the first actuation line is parallel to the XY plane when the first actuation line is not energized, the force generated after the first actuation line is energized does not have a component force along the optical axis of the lens. This can prevent the first base from moving away from the base along the optical axis during the image stabilization process, which can further improve the stability of the first base moving relative to the base in the first direction. It can also prevent the image stabilization process from interfering with the focusing process. This not only helps to improve the accuracy of image stabilization compensation motion and focusing accuracy, but also improves the clarity of the images captured by the camera module. It also makes the image stabilization process and the focusing process independent of each other, thus achieving accurate focusing while achieving accurate image stabilization.

[0015] In one possible implementation of the first aspect, when the first actuation line is not energized, the vertical distance between the first end and the reference plane is less than the vertical distance between the second end and the reference plane. This results in a smaller contraction of the first actuation line, allowing the first actuation component to achieve a larger stabilization stroke. On one hand, this allows for a larger stabilization compensation range within the linear contraction range of the first actuation line, which not only helps alleviate the limitation of optical image stabilization technology by the linear contraction range of the first actuation line, but also reduces the space occupied by the first actuation line in the circumferential direction of the first mount, thus reducing the width and / or length of the camera drive component and the camera module, facilitating the assembly of the camera module within the electronic device. On the other hand, with the same stabilization stroke, the contraction of the first actuation line in this embodiment is smaller, thereby shortening the contraction time of the first actuation line, improving the stabilization efficiency and effect of the stabilization drive component, and ultimately greatly improving the shooting quality of the camera module.

[0016] Furthermore, by positioning the second end of the first actuation line on the side of the first end away from the base, the force generated when the first actuation line is energized has a component parallel to the optical axis of the lens and pointing from the first mount towards the base. This component pulls the first mount towards the base along the optical axis, allowing the first mount to press firmly against the base during image stabilization. This prevents the first mount from moving away from the base along the optical axis during image stabilization, improving the stability of its movement relative to the base in the XY plane. It also prevents the image stabilization process from interfering with the focusing process. This not only improves the accuracy of image stabilization compensation and focusing, enhancing the clarity of images captured by the camera module, but also makes the image stabilization and focusing processes independent, thus achieving precise focusing while simultaneously achieving precise image stabilization.

[0017] In one possible implementation of the first aspect, when the first actuation line is not energized, the vertical distance between the first end and the reference plane is less than the vertical distance between the second end and the reference plane, and the angle between the line connecting the first end and the second end and the reference plane is less than or equal to 30 degrees. This allows for a larger anti-shake compensation range while reducing the space occupied by the anti-shake drive.

[0018] In one possible implementation of the first aspect, the base includes a first top surface facing the first body, and a first fixing boss is provided on the base, protruding from the first top surface. A first fixing member is fixedly connected to the first fixing boss. In this way, the first fixing boss can achieve relative fixation between the first fixing member and the base, and it is convenient to raise the position of the first fixing member, increasing the vertical distance between the first actuation line and the image sensor in the direction parallel to the optical axis, which helps to reduce the interference caused by the electrical signal in the first actuation line to the image sensor.

[0019] In one possible implementation of the first aspect, the camera driving assembly includes a plurality of first reset members, which are used to apply a force to the first seat body after the first seat body moves relative to the base in a first direction, so as to reset the first seat body.

[0020] Thus, when the first actuation wire is energized and contracts, it applies a first force along a first direction from the second fixing member to the first fixing member to the first base, causing the first base to move relative to the base. During this process, the first reset member undergoes elastic deformation, which balances and buffers the force on the first base, making its movement smoother. When the first actuation wire is de-energized and cools down, the first base can reset under the force provided by the first reset member, returning to its initial position. Furthermore, as the first base resets, it can drive the second fixing member to move relative to the first fixing member, allowing the first actuation wire to quickly return to its first form. Here, "the initial position of the first base" refers to the position of the first base when the first actuation wire is in its first form.

[0021] In one possible implementation of the first aspect, the first base includes a first side plate located circumferentially outside the carrier; at least one first reset member is disposed on the side of the first side plate facing away from the carrier. This allows full utilization of the space circumferentially outside the first base, reducing the superposition dimension of the first reset member and the first base in the optical axis direction, thereby reducing the overall volume of the camera driving assembly and achieving a miniaturized design of the camera driving assembly.

[0022] In one possible implementation of the first aspect, the first reset member located outside the first side plate and the first actuation unit located outside the first side plate are arranged in a direction parallel to the optical axis. This avoids interference between the first reset member and the first actuation unit.

[0023] In one possible implementation of the first aspect, the first reset member on the outer side of the first side plate is located on the side of the first actuation unit on the outer side of the first side plate away from the base. This avoids interference between the first actuation line and the first reset member when the first actuation line is de-energized and sags, thereby improving the operational reliability of the camera drive assembly.

[0024] In one possible implementation of the first aspect, the first reset member includes a first connecting portion, a second connecting portion, and an elastically deformable portion, the elastically deformable portion being connected between the first connecting portion and the second connecting portion. The first connecting portion is fixedly connected to the base, and the second connecting portion is fixedly connected to the first base body. This facilitates the assembly of the first reset member.

[0025] In one possible implementation of the first aspect, the extension and retraction direction of the first reset member is parallel to the XY plane.

[0026] In one possible implementation of the first aspect, the second actuation assembly includes two second actuation units arranged at a distance in a first direction. Each second actuation unit includes a third fixing member, a fourth fixing member, and a second actuation line. The third fixing member is fixed relative to the base. The fourth fixing member is fixedly connected to the second base body, and the fourth fixing member and the third fixing member are arranged at a distance in the second direction. The second actuation line is a shape memory alloy wire, and the two ends of the second actuation line are respectively connected to the first fixing member and the second fixing member.

[0027] Using shape memory alloy wire as the second actuation wire of the second actuation component can effectively increase the driving force of the first actuation component and reduce the volume of the first actuation component, thereby effectively compressing the overall volume of the entire camera drive component and realizing the miniaturization design of the camera module.

[0028] In one possible implementation of the first aspect, each first actuation unit includes a first actuation line, and each second actuation unit includes a first actuation line. Thus, the image stabilization drive is formed as a four-wire SMA drive motor. The four-wire SMA drive motor has a simple structure and occupies a small area, which helps to reduce the overall size of the camera drive assembly.

[0029] In one possible implementation of the first aspect, the second base includes a third side plate and a fourth side plate disposed opposite to each other in the first direction, the third side plate and the fourth side plate being located circumferentially outside the carrier; one of the two second actuation units is located on the side of the third side plate facing away from the fourth side plate, and the other second actuation unit is located on the side of the fourth side plate facing away from the third side plate. This increases the vertical distance between the second actuation line and the image sensor in the optical axis direction, which helps to reduce interference from the drive signal in the second actuation line to the image sensor. Furthermore, it reduces the superimposed dimensions of the second actuation unit, the base, and the second base in the optical axis direction of the lens, thereby reducing the height of the camera drive assembly, and consequently reducing the thickness of the camera module and the electronic device, which is beneficial for achieving a thinner design of the electronic device.

[0030] In one possible implementation of the first aspect, the first base includes a first side plate and a second side plate disposed opposite to each other in a second direction, and the second base includes a third side plate and a fourth side plate disposed opposite to each other in the first direction. The first, third, second, and fourth side plates are arranged sequentially in the circumferential direction of the carrier and enclose an installation space, within which the carrier is disposed. This simplifies the structure of the first and second bases, reducing their volume and weight, thereby reducing the load on the first and second actuation components and further reducing the energy consumption of the camera driving component. Furthermore, it avoids interference between the first base and the second actuation unit disposed circumferentially outside the second base, thus reducing the assembly difficulty of the camera driving component.

[0031] In one possible implementation of the first aspect, a first guide groove is provided between the first seat and the base, extending along a first direction; the camera driving assembly further includes a first guide member disposed within the first guide groove. When the first seat moves relative to the base along the first direction, the first guide member moves relative to the first guide groove along the first direction. In this way, the first guide member can restrict and guide the movement direction of the first seat relative to the base, ensuring that the first seat can move linearly relative to the base along the first direction, preventing deviation of the first seat's movement direction, thereby improving the stability of the first seat's movement relative to the base.

[0032] In one possible implementation of the first aspect, the first guide element is a ball bearing. This not only guides the movement direction of the first seat body but also reduces the friction between the first seat body and the base, thereby reducing the deviation between the target position and the actual movement position of the first seat body during image stabilization. This improves the control precision of the image stabilization process, ultimately reducing lens shake and enhancing shooting results.

[0033] In one possible implementation of the first aspect, the first guide element is a guide rod.

[0034] In one possible implementation of the first aspect, a second guide groove is provided between the first and second seats, extending along a second direction; the camera driving assembly further includes a second guide member disposed within the second guide groove. When the second seat moves relative to the first seat along the second direction, the second guide member and the second guide groove move relative to each other in the second direction. In this way, the movement direction of the second seat relative to the first seat can be restricted and guided by the second guide member, ensuring that the second seat can move linearly relative to the first seat along the second direction, preventing deviation of the second seat's movement direction, thereby improving the stability of the movement of the second seat relative to the first seat.

[0035] In one possible implementation of the first aspect, the camera driving assembly includes a focusing driving unit, a portion of which is connected to a carrier and another portion to a second base. The focusing driving unit drives the carrier to move axially relative to the second base along the lens mounting hole. This enables autofocus, and the focusing function of the camera module is achieved by driving the carrier to move relative to the second base. The focusing driving unit has a low load, which helps to reduce its size.

[0036] In one possible implementation of the first aspect, the focusing drive unit includes a first magnet and a coil, one of which is disposed on a second base and the other on a carrier; the first magnet and the coil cooperate to drive the carrier to move axially relative to the second base along the lens mounting hole. A specific structure of the focusing drive unit is provided.

[0037] In one possible implementation of the first aspect, the camera driving assembly includes a sliding assembly, which comprises a slider and a groove. The slider is disposed on one of the base and the carrier, and the groove is disposed on the other. When the carrier moves axially relative to the second base along the lens mounting hole, the slider and the groove slide in engagement. Thus, during autofocus, the movement direction of the carrier can be restricted and guided by the engagement of the slider and the groove, preventing deviation of the carrier's movement direction and thereby improving the stability of the carrier's movement relative to the second base.

[0038] In one possible implementation of the first aspect, the camera driving component includes a first metal part that magnetically engages with a first magnet. The arrangement direction of the first metal part and the first magnet is perpendicular to the axial direction of the lens mounting hole. One of the first metal part and the first magnet is disposed on a second base, and the other is disposed on a carrier.

[0039] In this way, the first magnet can generate a magnetic attraction force on the first metal component. Under the action of this magnetic attraction force, the carrier tends to move towards the second base as it moves relative to the second base along the optical axis of the lens. This ensures that the sliding component and the groove remain in contact, improving the guiding and restraining effect of the sliding assembly on the carrier, thereby further improving the stability of the carrier's movement relative to the base during autofocus. Furthermore, since both the first metal component and the coil can cooperate with the first magnet, there is no need to set up other magnets to cooperate with the first metal component. This not only avoids interference from the magnetic fields generated by other magnets on the coil, thus improving the focusing accuracy of the camera module, but also reduces the number of structural components and simplifies the structure of the camera drive assembly.

[0040] In one possible implementation of the first aspect, the camera driving assembly further includes a magnetic component, which includes a first magnetic member and a second magnetic member. The first magnetic member and the second magnetic member are magnetically attracted to each other and are arranged axially in the lens mounting hole. The first magnetic member is disposed on the second base and the second magnetic member is disposed on the base.

[0041] This reduces the likelihood of the first and second carriers tilting, thereby improving the stability of their movement during the anti-shake process and enhancing the control precision of the anti-shake process.

[0042] Secondly, this application provides a camera module, including: a camera driving component, a lens, and an image sensor. The camera driving component is any of the camera driving components described above. The lens is installed in a lens mounting hole. The image sensor is disposed on the side of the base facing away from the first base body.

[0043] In one possible implementation of the second aspect, the camera module includes a circuit board located on the side of the base away from the first body, and an image sensor disposed on the side of the circuit board facing the base.

[0044] Thirdly, this application provides an electronic device, including a screen, a back cover, and a camera module. The screen includes a light-transmitting cover and a display screen stacked on top of each other. The back cover includes a back cover and a frame, with the back cover and the light-transmitting cover respectively fixed to opposite ends of the frame. The light-transmitting cover, the back cover, and the frame form an accommodating space. The camera module is disposed within the accommodating space, with the light-incident surface of the camera module facing the back cover or the screen. The camera module is any of the camera modules described above.

[0045] Since the camera module and electronic device provided in this application include the camera driving component as described in any of the above technical solutions, they can solve the same technical problem and achieve the same technical effect, which will not be repeated here.

[0092] This application provides an electronic device with a shooting function. The camera driving component in this application involves two seats, a first seat and a second seat. A first actuation component drives the first seat to move relative to a base along a first direction (e.g., the X-axis), thereby causing the second seat, a carrier, and a lens to move together along the first direction. A second actuation component drives the second seat to move relative to the first seat along a second direction (e.g., the Y-axis), thereby causing the carrier and the lens to move along the second direction.

[0093] Since the lens's movement along the X-axis is achieved by the first actuation component driving the movement of the first mount, and the lens's movement along the Y-axis is achieved by the second actuation component driving the movement of the second mount, the control programs and algorithms for the lens in the X-axis and Y-axis directions can be independent of each other, achieving decoupling. This simplifies the control programs and algorithms for optical image stabilization, reduces the control difficulty of the stabilization process, improves the control accuracy of the stabilization process, and also helps reduce the energy consumption of the camera's drive components.

[0094] This application provides an electronic device, which is a type of electronic device with a shooting function. The electronic device in this application can be a mobile phone, tablet computer, laptop computer, camera, drone, smart home device, smart wearable device (e.g., smartwatch, smart bracelet, smart glasses, smart helmet), virtual reality (VR) electronic device, augmented reality (AR) electronic device, etc. This application does not impose any special limitations on the specific form of the electronic device.

[0095] Please see Figure 1 and combined Figure 2 , Figure 1 A perspective view of an electronic device 100 provided in some embodiments of this application. Figure 2 for Figure 1 An exploded view of the electronic device 100 is shown. In this embodiment, the electronic device 100 is described as a candybar mobile phone, but this should not be construed as a limitation of this application. The electronic device 100 includes a screen 10, a back cover 20, and a motherboard 30. Figure 1 (Not shown), camera module 40 and camera decorative cover 50.

[0096] Understandable Figure 1 and Figure 2 The electronic device 100 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2The limitations. In some other examples, the electronic device 100 may also not include the screen 10.

[0097] Screen 10 is used to display images, videos, etc. Please refer to [link / reference]. Figure 2 The screen 10 includes a light-transmitting cover 11 and a display screen 12. The light-transmitting cover 11 and the display screen 12 are stacked and fixedly connected. The light-transmitting cover 11 is mainly used to protect the display screen 12 and prevent dust. The material of the light-transmitting cover 11 includes, but is not limited to, glass, acrylic, etc. The display screen 12 can be a flexible display screen or a rigid display screen.

[0098] The back cover 20 is used to protect the internal electronic components of the electronic device 100. See also... Figures 1-2 The back cover 20 includes a back cover 21 and a frame 22. The back cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11, and is stacked with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the back cover 21 and the light-transmitting cover plate 11. The light-transmitting cover plate 11 and the back cover 21 can be fixed to opposite ends of the frame 22 respectively. The light-transmitting cover plate 11, the back cover 21, and the frame 22 form the internal receiving space of the electronic device 100.

[0099] The material of the back cover 21 includes, but is not limited to, metal, plastic, fiberglass, glass, ceramic, etc. It is understood that in some other embodiments, the screen 10 and the back cover 21 can also be the first screen and the second screen of the foldable phone, respectively. One of the first screen and the second screen can be the inner screen, and the other can be the outer screen. For example, the screen 10 is the inner screen of the foldable phone, and the back cover 21 is the outer screen of the foldable phone; or, the screen 10 is the outer screen of the foldable phone, and the back cover 21 is the inner screen of the foldable phone.

[0100] In some embodiments, please refer to Figure 2 The electronic device 100 also includes a middle plate 23. The middle plate 23 serves as the structural "skeleton" of the electronic device 100, and is fixed to the inner surface of the frame 22 around its perimeter. The middle plate 23 and the frame 22 can be formed as an integral structural component. That is, the middle plate 23 and the frame 22 can be integrally molded. Alternatively, the middle plate 23 and the frame 22 can also be connected by welding, bonding, screws, or other methods.

[0101] The motherboard 30 is used to integrate control chips. Control chips may include central processing units (CPU), graphics processing units (GPU), image signal processors (ISP), application processors (AP), double data rate synchronous dynamic random access memory (DDR), and universal flash storage (UFS), etc.

[0102] The motherboard 30 can be a rigid circuit board, a flexible circuit board, or a combination of both. The motherboard 30 can be electrically connected to the screen 10 to drive the screen 10 to display images.

[0103] In addition, the electronic device 100 may also include an external memory interface electrically connected to the control chip, an internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, etc. The sensor module may include pressure sensors, gyroscopes, Hall sensors, barometric pressure sensors, magnetic sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, touch sensors, ambient light sensors, and bone conduction sensors, etc.

[0104] The camera module 40 can be used to take photos, videos, etc. The camera module 40 is housed within the back cover 20 of the electronic device 100. Specifically, the camera module 40 is located within the internal storage space of the electronic device 100. The camera module 40 can be used as a rear camera module or a front camera module.

[0105] In some embodiments, please refer to Figure 2 The camera module 40 can be fixed to the surface of the middle plate 23 facing the back cover 21, with the light-incident surface of the camera module 40 facing the back cover 21. The back cover 21 has a mounting opening 211, and the camera decorative cover 50 covers and is fixed to the mounting opening 211. The camera decorative cover 50 is used to protect the camera module 40. The camera decorative cover 50 has a light-transmitting window 51. The light-transmitting window 51 allows light from the scene to enter the light-incident surface of the camera module 40. In this embodiment, the camera module 40 is used as a rear camera module of the electronic device 100.

[0106] In other embodiments, the camera module 40 can also be fixed to the surface of the middle plate 23 facing the light-transmitting cover plate 11. In this case, the light-incident surface of the camera module 40 faces the light-transmitting cover plate 11. The display screen 12 is provided with a light path avoidance hole. This light path avoidance hole allows light from the scene to pass through the light-transmitting cover plate 11 and then enter the light-incident surface of the camera module 40. In this way, the camera module 40 can be used as a front-facing camera module of the electronic device 100.

[0107] The camera module 40 can be one or more of a standard camera module, a telephoto camera module, a wide-angle camera module, an ultra-telephoto camera module, and an ultra-wide-angle camera module. This application embodiment does not limit the number of camera modules 40. Figure 1 and Figure 2 This example illustrates the concept of a rear camera module consisting of three camera modules (40).

[0108] Please see Figure 3 and combined Figure 4 , Figure 3 A perspective view of a camera module 40 provided in some embodiments of this application. Figure 4 for Figure 3 The image shows an exploded view of the camera module 40. The camera module 40 includes a lens 41, a camera drive assembly 42, a variable aperture 43, a circuit board 441, an image sensor 442, and a filter 443.

[0109] Understandable Figures 3-4 The images only schematically illustrate some of the components included in the camera module 40. The actual shape, size, position, and construction of these components are not subject to change. Figure 3 and Figure 4 As defined in the accompanying drawings below. For example, in some other embodiments, the camera module 40 may not include at least one of the variable aperture and the filter 443.

[0110] For ease of description in the following embodiments, an XYZ coordinate system is established for the camera module 40. The optical axis O1 of the lens 41 can be the Z-axis. The XY plane formed by the X-axis and Y-axis is perpendicular to the optical axis O1 of the lens 41. In some embodiments, after the camera module 40 is assembled into the electronic device 100, the optical axis O1 of the lens 41 can be parallel to the thickness direction of the electronic device 100. The plane formed by the width and length directions of the electronic device 100 is parallel to the XY plane.

[0111] It should be noted that the optical axis O1 of lens 41 can refer to the direction in which the optical system of lens 41 transmits light. For example, for a symmetrical lens 41, the optical axis O1 can coincide with the rotation center line of the optical system of lens 41. The optical axis O1 of the aforementioned lens 41 can serve as the optical axis of the camera module 40.

[0112] Furthermore, the term "top" used in describing the orientation of each component in the camera module 40 below refers to the side of the component being described that is closer to the object being photographed along the light path; and "bottom" refers to the side of the component being described that is farther away from the object being photographed along the light path. This is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0113] Please see Figure 4 and combined Figure 5 , Figure 5 for Figure 3 The image shows a cross-sectional view of the camera module 40 at line AA. The lens 41 may include a lens barrel 411 and an optical lens group 412. The lens barrel 411 is used to fix and protect the optical lens group 412. The lens barrel 411 has a mounting hole in the middle that extends along the optical axis O1.

[0114] An optical lens group 412 is mounted inside the lens barrel 411. The optical lens group 412 transmits light from the scene and forms an image of the subject. The optical lens group 412 may include one or more optical lenses. These optical lenses can be convex lenses, concave lenses, or plane mirrors. When the optical lens group 412 includes multiple optical lenses, these lenses are arranged sequentially along the optical axis O1 of the lens 41 within the lens barrel 41. By designing the structural composition of the optical lens group 412 and the shape and size of each optical lens, lenses 41 with different characteristics such as wide-angle and telephoto can be obtained.

[0115] Please see Figure 5 Lens 41 includes an incident light surface 41a and an exit light surface 41b. In some embodiments, the incident light surface 41a and the exit light surface 41b face away from each other. The incident light surface 41a is the surface of the object being photographed that the lens 41 faces during use. Light from the object enters the lens 41 through the incident light surface 41a and exits through the exit light surface 41b. For example, in... Figure 5 In the image, the direction of light propagation is indicated by a black dashed line with an arrow.

[0116] The camera drive assembly 42 can be used to drive the lens 41 to move in a plane perpendicular to the optical axis O1 to achieve optical image stabilization (OIS). Alternatively, the camera drive assembly 42 can also be used to drive the lens 41 to move along the optical axis O1 to achieve automatic focusing (AF) of the lens 41.

[0117] In some embodiments, the lens 41 can be mounted on the camera driver assembly 42 via the lens barrel 411. In other embodiments, to simplify the structure of the camera module 40, the lens 41 may not include the lens barrel 411. In this case, the optical lens group 412 can be directly mounted on the camera driver assembly 42.

[0118] Please see Figures 4-5 The variable aperture 43 has an aperture opening 431 of variable size. By adjusting the size of the aperture opening 431, the amount of light entering the lens 41 can be adjusted. The variable aperture 43 can be fixedly connected to the lens 41 or fixedly connected to the camera driver assembly 42.

[0119] For details, please refer to Figure 5 The aperture 431 is located on the light-incident side of the lens 41, and the aperture 431 is opposite to the light-incident surface 41a of the lens 41, so that light from the scene can enter the lens 41 through the aperture 431. In some embodiments, the central axis of the aperture 431 is collinear with the optical axis O1 of the lens 41.

[0120] In this context, the light-incident side of lens 41 refers to the side facing which the light-incident surface 41a of lens 41 faces. The light-exiting side of lens 41 refers to the side facing which the light-exiting surface 41b of lens 41 faces.

[0121] In order for the light incident on the camera module 40 to undergo photoelectric conversion to generate image information, please refer to Figure 4 and Figure 5 The camera module 40 may also include a circuit board 441, an image sensor 442, and a filter 443.

[0122] The circuit board 441 can be used to electrically connect the camera module 40 to external circuitry. In some embodiments, the circuit board 441 can be electrically connected to the motherboard 30 of the electronic device 100. See also... Figure 5 The circuit board 441 is located on the light-emitting side of the lens 41. The circuit board 441 can be a rigid circuit board or a flexible circuit board.

[0123] Image sensor 442 is used to acquire the imaging beam after it has passed through lens 41 and convert the image information carried by the imaging beam into electrical signals. Image sensor 442 can also be called a photosensitive chip or photosensitive element. Please refer to [link to relevant documentation]. Figure 5 The image sensor 442 can be disposed on the circuit board 441 and electrically connected to the circuit board 441. The side surface of the image sensor 442 opposite to the circuit board 441 includes a photosensitive area, and the photosensitive area is provided with multiple photosensitive units. Each photosensitive unit can convert the amount of light in the photosensitive area into an electrical signal that is proportional to the amount of light.

[0124] The filter 443 can be used to filter stray light in the imaging beam after it has passed through the lens 41, thereby ensuring that the image captured by the camera module 40 has better clarity. Please refer to... Figure 4 and Figure 5 The filter 443 is located on the side of the image sensor 442 opposite to the circuit board 441. To enable the installation of the filter 443, the camera module 40 also includes a mounting bracket 444, which can fix the filter 443 to the circuit board 441.

[0125] Filter 443 can be an infrared filter, which can filter out infrared light in ambient light and allow visible light to pass through. Alternatively, filter 443 can be a dual bandpass filter, which can select two wavelengths in two regions of ambient light to pass through, such as visible light and infrared light, or visible light and ultraviolet light, or ultraviolet light and infrared light, etc.

[0126] Please see Figure 6 , Figure 6 for Figure 4 An exploded view of the camera driving assembly 42 in the camera module 40 shown. The camera driving assembly 42 includes a base 421, a seat 422, a carrier 423, and a cover 424.

[0127] The base 421 provides support for other structural components of the camera module 40. The base 421 is generally plate-shaped. For example, the base 421 can be formed as a rectangle, circle, ellipse, etc. The thickness direction of the base 421 is parallel to the Z-axis direction. For details, please refer to... Figure 6 The base 421 includes its thickness direction (i.e., Figure 6 The base 421 has a first top surface 4211 and a first bottom surface 4212 facing each other on the Z-axis direction. A first through hole K1 is provided on the base 421, which penetrates the first top surface 4211 and the first bottom surface 4212. The shape of the first through hole K1 includes, but is not limited to, a circle, a rectangle, an ellipse, a polygon, an irregular shape, etc.

[0128] The base 422 can be disposed on the base 421. Specifically, the base 422 can be located on the side facing the first top surface 4211 of the base 421. Please refer to [link / reference]. Figure 6 The seat 422 has a receiving cavity Q, and a second through hole K2 communicating with the receiving cavity Q is provided on the seat 422. The second through hole K2 is opposite to and communicates with the first through hole K1. The shape of the second through hole K2 includes, but is not limited to, a circle, a rectangle, an ellipse, a polygon, an irregular shape, etc. The central axis of the second through hole K2 may be parallel to or coincide with the central axis of the first through hole K1.

[0129] The carrier 423 can be disposed within the accommodating cavity Q. Please refer to [link / reference]. Figure 6 The carrier 423 has a lens mounting hole 423a, which is a through hole. The axial direction of the lens mounting hole 423a is the same as the optical axis of the lens 41. For example, the central axis of the lens mounting hole 423a coincides with or is parallel to the optical axis of the lens 41. Furthermore, the central axis of the lens mounting hole 423a can also be parallel to or coincide with the central axis of the second through hole K2.

[0130] For example, the carrier 423 can be formed as a ring frame structure. The lens 41 can be mounted in the lens mounting hole 423a. In some embodiments, the lens 41 is detachably connected to the carrier 423 to facilitate the replacement of the lens 41.

[0131] Please see Figure 5 The lens 41 can be inserted through the second through hole K2, and the light-emitting surface 41b of the lens 41 is exposed through the first through hole K1. For example, one end of the lens 41 with the light-emitting surface 41b can be located inside the first through hole K1. In this way, on the one hand, the base 421, the seat 422, etc. can be prevented from blocking the light-emitting surface 41b of the lens 41, so that the light emitted from the lens 41 can smoothly enter the image sensor 442; on the other hand, the size of the camera module 40 in the optical axis O1 direction can be reduced, which is conducive to reducing the thickness of the electronic device 100 and realizing the thin design of the electronic device 100.

[0132] Please see Figure 5 The housing 424 can be fixedly connected to the base 421 and covers the seat 422 and carrier 423 to prevent dust. The materials of the housing 424 include, but are not limited to, plastic and metal. The housing 424 and the base 421 can together form the outer shell of the camera driving assembly 42.

[0133] In some embodiments, please refer to Figure 5 and combined Figure 6The housing 424 includes a first top plate 4241 and a first side plate 4242. The first side plate 4242 is annular and surrounds the outer periphery of the edge of the first top plate 4241. The first top plate 4241 and the base 421 are located at opposite ends of the first side plate 4242. The first top plate 4241, the first side plate 4242, and the base 421 can form a receiving cavity for accommodating the seat 422, the carrier 423, etc.

[0134] A third through hole K3 is provided on the first top plate 4241. The central axis of the third through hole K3 can be parallel to or coincide with the optical axis O1 of the lens 41. Please refer to [link / reference]. Figure 5 A portion of the lens 41 can be located within the aforementioned receiving cavity, and the light-incident surface 41a of the lens 41 is exposed through the third through-hole K3. To ensure the movement space of the lens 41, there is a clearance between the inner wall of the third through-hole K3 and the variable aperture and the lens 41.

[0135] To achieve optical image stabilization in the camera module 40, please refer to the following embodiments: Figure 6 The camera driving assembly 42 also includes an image stabilization driving component 426. Specifically, the image stabilization driving component 426 includes a first actuation component 426a and a second actuation component 426b. The first actuation component 426a provides a resultant force along a first direction e1 to the mount 422 to drive the mount 422 to move along the first direction e1. The second actuation component 426b provides a resultant force along a second direction e2 to the mount 422 to drive the mount 422 to move along the second direction e2. Both the first direction e1 and the second direction e2 are perpendicular to the axial direction of the lens mounting hole 423a, and the first direction e1 is perpendicular to the second direction e2. For example, the first direction e1 is parallel to the X-axis direction, and the second direction e2 is parallel to the Y-axis direction.

[0136] In this way, the image stabilization drive 426 can apply a force parallel to the XY plane to the base, driving the base to move along the XY plane. Since the base 422 and the carrier 423 carrying the lens 41 can translate relative to the base 421 simultaneously, the image stabilization drive 426 can drive the lens 41 to move in the XY plane, enabling the camera module 40 to achieve optical image stabilization.

[0137] However, in this embodiment, the movements of the seat 422 in the X-axis and Y-axis directions are interconnected and not decoupled. The control algorithm for the image stabilization process is relatively complex, and the control accuracy of the image stabilization process is low, which affects the shooting quality of the camera module 40.

[0138] To resolve the above technical issues, please refer to Figure 7 and combined Figure 8 , Figure 7 A perspective view of a camera driver assembly 42 provided in other embodiments of this application. Figure 8 for Figure 7 The exploded view shown is of the camera driving assembly 42. In this embodiment, the camera driving assembly 42 includes a base 421, a first base body 422a, a second base body 422b, a carrier 423, and a housing 424. The structures of the base 421, carrier 423, and housing 424 in this embodiment can be referred to respectively. Figure 6 The base 421, carrier 423 and cover 424 in the illustrated embodiment are designed and will not be described in detail here.

[0139] Please see Figure 8 The first base 422a includes a first support plate 422a1, a first side plate 422a2, and a second side plate 422a3. The first side plate 422a2 and the second side plate 422a3 are both fixedly connected to the first support plate 422a1, and the first side plate 422a2 and the second side plate 422a3 are arranged opposite to each other in the second direction e2.

[0140] The first support plate 422a1 may be plate-shaped, and its shape may be substantially the same as that of the base 421. A first through hole K21 is provided on the first support plate 422a1, which may be opposite to the lens mounting hole 423a. For example, the central axis of the first through hole K21 coincides with the central axis of the lens mounting hole 423a. Both the first side plate 422a2 and the second side plate 422a3 may be formed as flat plates.

[0141] The second base 422b includes a second support plate 422b1, a third side plate 422b2, and a fourth side plate 422b3. The third side plate 422b2 and the fourth side plate 422b3 are both fixedly connected to the second support plate 422b1, and are arranged opposite to each other in the first direction e1. Both the third side plate 422b2 and the fourth side plate 422b3 can be formed as flat plates.

[0142] The second support plate 422b1 may be plate-shaped, and its shape is substantially the same as that of the first support plate 422a1. A second through hole K22 is provided on the second support plate 422b1, which is opposite to the first through hole K21.

[0143] Please see Figure 9a , Figure 9a for Figure 7 The image shows a perspective view of the camera driver assembly 42 after removing the cover 424. A first base 422a is disposed on a base 421, and a second base 422b is disposed on the first base 422a, with at least a portion of the second base 422b located on the side of the first base 422a facing away from the base 421. A carrier 423 is disposed on the second base 422b.

[0144] Please see Figure 9a and combined Figure 9b , Figure 9b for Figure 9a The diagram shows the assembly of the base 421, the first mounting body 422a, and the second mounting body 422b in the camera driving assembly 42. The first mounting body 422a can be disposed on the side facing the first top surface 4211 of the base 421. The first support plate 422a1 and the base 421 are axially aligned with the lens mounting hole 423a (that is,...). Figure 9b The second support plate 422b1 and the first support plate 422a1 are stacked on the Z-axis direction, and the second support plate 422b1 is located on the side of the first support plate 422a1 facing away from the base 421.

[0145] The first side plate 422a2, the second side plate 422a3, the third side plate 422b2, and the fourth side plate 422b3 can all be located on the circumferential outer side of the carrier 423. In this embodiment, the first side plate 422a2 and the second side plate 422a3 are spaced apart circumferentially from the carrier 423. It is understood that in other embodiments, the first side plate 422a2 and the second side plate 422a3 may also be joined together circumferentially to form a ring. In this case, the first base 422a may include the first support plate 422a1, or it may not include the first support plate 422a1. Alternatively, in other embodiments, the first base 422a may include only the first support plate 422a1, without including at least one of the first side plates 422a2 and the second side plate 422a3.

[0146] Similarly, in other embodiments, the third side plate 422b2 and the fourth side plate 422b3 may also be joined in the circumferential direction of the carrier 423 to form a ring. Alternatively, the second seat 422b may include only the second support plate 422b1, without including at least one of the third side plate 422b2 and the fourth side plate 422b3.

[0147] Please see Figure 10 , Figure 10 for Figure 8 This is a schematic diagram of the image stabilization driver 426 in the camera driver assembly 42. The image stabilization driver 426 includes a first actuation component 426a and a second actuation component 426b. The first actuation component 426a provides a force along a first direction e1 to the first base 422a, thereby driving the first base 422a to move relative to the base 421 along the first direction e1. A portion of the first actuation component 426a can be fixed relative to the base 421, and another portion can be connected to the first base 422a.

[0148] The second actuation component 426b is used to provide a resultant force along the second direction e2 to the second seat 422b, so as to drive the second seat 422b to move relative to the first seat 422a along the second direction e2. A portion of the second actuation component 426b can be fixed relative to the base 421, and another portion can be connected to the first seat 422a.

[0149] Specifically, when the first seat 422a moves relative to the base 421 along the first direction e1, it can drive the second seat 422b and the carrier 423 to move along the first direction e1, thereby driving the lens 41 to move along the first direction e1. When the second seat 422b moves relative to the first seat 422a along the second direction e2, it can drive the carrier 423 and the lens 41 inside the carrier 423 to move along the second direction e2.

[0150] In this way, the first actuation component 426a can control the first base 422a to move along the first direction e1, thereby realizing the movement of the lens 41 in the first direction e1. The second actuation component 426b can control the second base 422b to move along the second direction e2, thereby realizing the movement of the lens 41 in the second direction e2. Thus, the lens 41 can be translated in the XY plane.

[0151] Since the first seat 422a and the second seat 422b are driven by two different sets of actuators, the first actuator 426a and the second actuator 426b, respectively, and the movements of the first seat 422a and the second seat 422b in the XY plane are independent of each other, the control programs and algorithms of the lens 41 in the first direction e1 and the second direction e2 can be independent of each other and do not affect each other, thus achieving decoupling.

[0152] Therefore, on the one hand, it simplifies the control procedures and algorithms of the optical image stabilization process, reduces the control difficulty of the optical image stabilization process, thereby shortening the response time of the stabilization process and improving the stabilization efficiency; on the other hand, it improves the control precision of the stabilization process, making the stabilization compensation motion of the camera module 40 more precise, thereby further improving the shooting quality of the camera module 40; furthermore, when the lens 41 only needs to move along the first direction e1, the second actuation component 426b does not need to work, and similarly, when the lens 41 only needs to move along the second direction e2, the first actuation component 426a does not need to work, which reduces the power consumption of the camera drive component 42, which is beneficial to extending the battery life of the electronic device 100 and avoiding signal interference between the two sets of actuation components; furthermore, when the second actuation component 426b drives the second base 422b to move along the second direction e2, it does not need to drive the first base 422a to move, which reduces the load on the second actuation component 426b, which is beneficial to further reduce the power consumption of the camera drive component 42 and further improve the control precision of the stabilization process.

[0153] In some embodiments, please refer to Figure 10 The first actuation assembly 426a includes two first actuation units 4261, which are arranged opposite to each other in the second direction e2. Each first actuation unit 4261 includes a first fixing member 4261a, a second fixing member 4261b, and a first actuation line 4261c.

[0154] Please see Figure 9b The first fixing member 4261a can be fixed relative to the base 421, and the second fixing member 4261b can be fixedly connected to the first base body 422a. A first actuation line 4261c is connected to the first fixing member 4261a, and the first actuation line 4261c is connected to the second fixing member 4261b. The first fixing member 4261a and the second fixing member 4261b can be arranged in a first direction e1. Each first actuation unit 4261 may include one first actuation line 4261c.

[0155] Please see Figure 10 The two first actuation units 4261 include two first fixing members 4261a and two second fixing members 4261b, which are alternately arranged in the circumferential direction of the carrier 423. In some embodiments, the two first fixing members 4261a and the two second fixing members 4261b are respectively distributed at the four corner positions of the rectangle, and the two first fixing members 4261a are arranged on one diagonal of the rectangle, while the two second fixing members 4261b are arranged on the other diagonal of the rectangle.

[0156] In some embodiments, both the first fixing member 4261a and the second fixing member 4261b can be metal parts. In this way, the first fixing member 4261a and the second fixing member 4261b can serve as wiring terminals of the first actuation unit 4261, which facilitates the electrical connection between the first actuation unit 4261 and the circuit board 441 of the camera module 40.

[0157] The first actuation line 4261c is a shape memory alloy component. Specifically, the first actuation line 4261c can be a wire structure made of shape memory alloy material. Shape memory alloys are materials composed of two or more metallic elements that exhibit shape memory effects through thermoelastic and martensitic phase transformations and their inverse transformations, and possess the characteristics of thermal contraction and thermal expansion. For example, the shape memory alloy can be a nickel-titanium alloy material.

[0158] Therefore, when the first actuation line 4261c is energized, it converts some electrical energy into heat energy due to its resistive characteristics. Under the influence of its own heat, the first actuation line 4261c contracts, and its length decreases. When the energization to the first actuation line 4261c is stopped, its temperature decreases, and it can recover its deformation, allowing its length to increase.

[0159] Specifically, the first actuation line 4261c includes a first mode (i.e., the state when power is off) and a second mode (i.e., the state when power is on), and can switch between the first mode and the second mode. Please refer to [link / reference]. Figure 11 , Figure 11 for Figure 10 A schematic diagram of a single first actuation unit 4261 in the camera driving assembly 42 shown. Wherein, Figure 11 The first actuation unit 4261 shown in (a) is in the first configuration, with the first actuation line 4261c in the first configuration. Figure 11 The first actuation unit 4261 shown in (b) has the first actuation line 4261c in the second configuration.

[0160] The first connecting line 4261c includes a first end A and a second end B. The first end A can be connected to the first fixing member 4261a, and the second end B can be connected to the second fixing member 4261b. The first end A and the first fixing member 4261a can be fixed by welding, bonding, snap-fitting, screw connection, or other methods. The second end B and the second fixing member 4261b can be fixed by welding, bonding, snap-fitting, screw connection, or other methods.

[0161] like Figure 11 As shown in (a), in the first configuration, the distance between the first end A and the second end B of the first actuation line 4261c is the first length L1, as follows: Figure 11 As shown in (b), in the second configuration, the distance between the first end A and the second end B of the first actuation line 4261c is a second length L2. The first length L1 is greater than the second length L2.

[0162] In this way, during the image stabilization process, the first actuation line 4261c can be energized, causing it to contract and shorten. Since the first fixing member 4261a is relatively fixed to the base 421, and the second fixing member 4261b is connected to the first seat body 422a, during the contraction and shortening of the first actuation line 4261c, it can apply a pulling force to the first seat body 422a, pulling it to move relative to the base 421 along the first direction e1, thereby generating a compensation stroke for optical image stabilization and achieving optical image stabilization. Simultaneously, in this embodiment of the camera driving assembly 42, the use of a shape memory alloy as the first actuation line 4261c of the first actuation assembly 426a effectively increases the driving force of the first actuation assembly 426a and reduces its volume, thus effectively compressing the overall volume of the entire camera driving assembly 42 and achieving a miniaturized design of the camera module 40.

[0163] Please see Figure 10 The second actuation assembly 426b includes two second actuation units 4262, which are arranged opposite to each other in a first direction e1. Each second actuation unit 4262 includes a third fixing member 4262a, a fourth fixing member 4262b, and a second actuation line 4262c. The third fixing member 4262a and the fourth fixing member 4262b are arranged at intervals in a second direction e2. The second actuation line 4262c is connected to the third fixing member 4262a and the fourth fixing member 4262b. The second actuation line 4262c is a shape memory alloy wire.

[0164] Please see Figure 9b The third fixing member 4262a is fixed relative to the base 421, and the fourth fixing member 4262b is fixedly connected to the second base body 422b. In some embodiments, both the third fixing member 4262a and the fourth fixing member 4262b can be metal parts. In this way, the third fixing member 4262a and the fourth fixing member 4262b can serve as wiring terminals for the second actuation unit 4262, facilitating the electrical connection between the second actuation unit 4262 and the circuit board 441 of the camera module 40.

[0165] In some embodiments, each second actuation unit 4262 includes a second actuation line 4262c. In this case, the image stabilization drive 426 in this embodiment can be formed as a four-wire SMA drive. The four-wire SMA drive motor has a simple structure and occupies a small area, which is beneficial to reducing the overall size of the camera drive assembly 42.

[0166] Please see Figure 10The two second actuation units 4262 include two third fixing members 4262a and two fourth fixing members 4262b, which are alternately arranged in the circumferential direction of the carrier 423. In some embodiments, the two third fixing members 4262a and the two fourth fixing members 4262b are respectively distributed at the four corner positions of the rectangle, and the two third fixing members 4262a are arranged on one diagonal of the rectangle, while the two fourth fixing members 4262b are arranged on the other diagonal of the rectangle.

[0167] In this way, during the image stabilization process, the second actuation line 4262c can be energized, causing it to contract and shorten. Since the third fixing member 4262a is relatively fixed to the base 421, and the fourth fixing member 4262b is connected to the second seat 422b, during the contraction and shortening process, the second actuation line 4262c can apply a pulling force to the second seat 422b, causing it to move relative to the first seat 422a along the second direction e2, thereby generating a compensation stroke for optical image stabilization and achieving optical image stabilization. Simultaneously, using a shape memory alloy as the second actuation line 4262c of the second actuation component 426b effectively increases the driving force of the second actuation component 426b and reduces its volume, thus effectively compressing the overall volume of the entire camera drive component 42 and achieving a miniaturized design of the camera module 40.

[0168] In some embodiments, please refer to Figure 10 In the circumferential direction of the carrier 423, the first fixing member 4261a of the first actuation unit 4261 and the third fixing member 4262a of the second actuation unit 4262 are arranged adjacent to each other, or the second fixing member 4261b of the first actuation unit 4261 and the fourth fixing member 4262b of the second actuation unit 4262 are arranged adjacent to each other.

[0169] Please see Figure 12 , Figure 12 for Figure 9a The image shows a top view of the camera driving assembly 42. In this embodiment, the top view refers to a schematic diagram looking from the side facing the first top surface 4211 of the base 421 towards the first bottom surface 4212 of the base 421. For ease of description, the two first actuation lines 4261c are respectively recorded as actuation line s1 and actuation line s2, and the two second actuation lines 4262c are respectively recorded as actuation line s3 and actuation line s4.

[0170] When it is necessary to drive the lens 41 to move along the positive X-axis, a current I1 can be passed into the actuation line s1 and a current I2 can be passed into the actuation line s2, where the current I2 is less than the current I1. Actuation lines s3 and s4 can be de-energized. That is, the second actuation component 426b can be de-energized. In this way, actuation line s1 can provide a pulling force f1 along the positive X-axis (X+), and actuation line s2 can provide a pulling force f2 along the negative X-axis (X-). Since f1 is greater than f2, the resultant force provided by actuation lines s1 and s2 is along the positive X-axis. Thus, under the action of actuation lines s1 and s2, the first base 422a can move along the positive X-axis, and rotation of the first base 422a in the XY plane can be avoided. Therefore, the lens 41 can be moved along the positive X-axis.

[0171] When it is necessary to drive the lens 41 to move along the positive Y-axis, a current I3 can be passed into the actuation line s3 and a current I4 can be passed into the actuation line s4, where the current I3 is less than the current I4. Actuation lines s1 and s2 can be de-energized. That is, the first actuation component 426a can be de-energized. In this way, actuation line s3 can provide a pulling force f3 along the positive Y-axis (Y+), and actuation line s4 can provide a pulling force f4 along the negative Y-axis (Y-). Since f3 is less than f4, the resultant force provided by actuation lines s3 and s4 extends along the positive Y-axis. Thus, under the action of actuation lines s3 and s4, the second base 422b can move along the positive Y-axis, and rotation of the second base 422b in the XY plane can be avoided. Therefore, the lens 41 can be moved along the positive Y-axis.

[0172] This reduces the power consumption of the camera driver component 42, which helps extend the battery life of the electronic device 100. Furthermore, the calculation program for the image stabilization process is simple, which reduces the control difficulty of the image stabilization process and improves the control accuracy of the image stabilization process, which helps improve the shooting quality of the camera module 40.

[0173] It is understood that in other embodiments, at least one of the first actuation component 426a and the second actuation component 426b may be designed as a voice coil driver, as long as the first actuation component 426a can drive the first seat 422a to move relative to the base 421 in the first direction e1, and the second actuation component 426b can drive the second seat 422b to move relative to the first seat 422a in the second direction e2.

[0174] In some embodiments, please refer back to the reference. Figure 8 and combined Figure 9bOne of the two first actuation units 4261 can be disposed on the side of the first side plate 422a2 facing away from the second side plate 422a3, and the other first actuation unit 4261 can be disposed on the side of the second side plate 422a3 facing away from the first side plate 422a2. That is, both first actuation units 4261 are located on the circumferential outer side of the first base 422a.

[0175] For example, the second fixing member 4261b of one of the two first actuation units 4261 can be fixedly connected to the first side plate 422a2, and the second fixing member 4261b of the other first actuation unit 4261 can be fixedly connected to the second side plate 422a3.

[0176] Since the image sensor 442 in the camera module 40 is usually located on the side of the base 421 facing away from the first seat 422a, by setting the first actuation unit 4261 on the circumferential outer side of the first seat 422a, the position of the first actuation line 4261c relative to the image sensor 442 can be raised, thereby increasing the vertical distance between the first actuation line 4261c and the image sensor 442 in the optical axis direction. This helps to reduce the interference caused by the drive signal in the first actuation line 4261c to the image sensor 442, thereby improving the imaging clarity of the image sensor 442 and improving the shooting effect of the camera module 40.

[0177] In addition, by placing the first actuation unit 4261 on the circumferential outer side of the first base 422a, the space on the side of the first base 422a can be fully utilized, reducing the superimposed size of the first actuation unit 4261, the base 421 and the first base 422a in the optical axis direction of the lens 41. This reduces the height of the camera driving assembly 42, and consequently reduces the thickness of the camera module 40 and the electronic device 100, which is beneficial for achieving a thinner design of the electronic device 100.

[0178] Please continue reading. Figure 8 and combined Figure 9b One of the two second actuation units 4262 can be disposed on the side of the third side plate 422b2 facing away from the fourth side plate 422b3, and the other second actuation unit 4262 can be disposed on the side of the third side plate 422b2 facing away from the fourth side plate 422b3. That is, both second actuation units 4262 are located on the circumferential outer side of the second base 422b. For example, the fourth fixing member 4262b of one second actuation unit 4262 can be fixedly connected to the third side plate 422b2, and the fourth fixing member 4262b of the other second actuation unit 4262 can be fixedly connected to the fourth side plate 422b3.

[0179] This increases the vertical distance between the second actuation line 4262c and the image sensor 442 along the optical axis, which helps reduce the interference caused by the drive signal in the second actuation line 4262c to the image sensor 442, thereby improving the imaging clarity of the image sensor 442 and enhancing the shooting effect of the camera module 40. Simultaneously, it reduces the superimposed dimensions of the second actuation unit 4262, the base 421, and the second seat body 422b along the optical axis, thus reducing the height of the camera drive assembly 42 and consequently the thickness of the camera module 40 and the electronic device 100, facilitating a thinner design for the electronic device 100.

[0180] It is understood that in other embodiments, the first actuation unit 4261 may also be disposed at the bottom of the base 421 or at the top of the first seat 422a. Similarly, the second actuation unit 4262 may also be disposed at the bottom of the base 421 or at the top of the second seat 422b.

[0181] In some embodiments, please refer to Figure 9a The first side plate 422a2, the third side plate 422b2, the second side plate 422a3, and the fourth side plate 422b3 can be arranged sequentially along the circumference of the carrier 423 to form an installation space, within which the carrier 423 is disposed. This simplifies the structure of the first base 422a and the second base 422b, reducing their volume and weight, thereby reducing the load on the first actuation assembly 426a and the second actuation assembly 426b, and further reducing the energy consumption of the camera drive assembly 42. Furthermore, it avoids interference between the first base 422a and the second actuation unit 4262 located circumferentially outside the second base 422b, thus reducing the assembly difficulty of the camera drive assembly 42.

[0182] To fix the first actuation unit 4261, please refer to... Figure 9b The base 421 is provided with a first fixing boss 429. Specifically, the first fixing boss 429 protrudes from the first top surface 4211 of the base 421. Exemplarily, the first fixing boss 429 may be disposed on the first top surface 4211 of the base 421. Alternatively, in some other embodiments, the first fixing boss 429 may also be disposed on the outer peripheral surface of the base 421. Here, the outer peripheral surface of the base 421 refers to the surface connecting the first top surface 4211 and the first bottom surface 4212 of the base 421.

[0183] In this way, by setting the first fixed boss 429, the first fixing member 4261a and the base 421 can be relatively fixed, and it is convenient to raise the position of the first fixing member 4261a, increase the vertical distance between the first actuation line 4261c and the image sensor 442 in the direction parallel to the optical axis, which is beneficial to reduce the interference of the electrical signal in the first actuation line 4261c on the image sensor 442.

[0184] The number of first fixed bosses 429 can be the same as the number of first actuation units 4261. (See also...) Figure 8 In this embodiment, there are two first fixing bosses 429, which are arranged circumferentially on the base 421. For example, the two first fixing bosses 429 can be respectively disposed at two corner positions of the base 421.

[0185] In some embodiments, the first fixing boss 429 and the base 421 can be integrally formed. For example, the first fixing boss 429 and the base 421 can be integrally injection molded. Alternatively, the first fixing boss 429 and the base 421 can also be fixedly connected by means of bonding, welding, screw connection, etc. It is understood that in other embodiments, the first fixing member 4261a can also be fixedly connected to the cover 424, as long as the first fixing member 4261a and the base 421 can maintain relative fixation.

[0186] In some embodiments, please refer to Figure 9a The surface of the first side plate 422a2 facing away from the carrier 423 (i.e., the outer surface of the first side plate 422a2) includes a first fixed area n1 and a first clearance area n2, with the first clearance area n2 recessed relative to the first fixed area n1 towards the carrier 423. A second fixing member 4261b is fixedly connected to the first fixed area n1. A first actuation line 4261c is opposite to and spaced apart from the first clearance area n2 in the second direction e2. That is, the first actuation line 4261c does not contact the first clearance area n2. This avoids friction between the first actuation line 4261c and the first side plate 422a2 during contraction or extension, thereby reducing energy loss and improving the accuracy of the anti-shake compensation motion stroke.

[0187] The structure of the second side plate 422a3 can be the same as that of the first side plate 422a2, and the way the second fixing member 4261b connects to the second side plate 422a3 can be the same as the way the second fixing member 4261b connects to the first side plate 422a2. Furthermore, the way the third fixing member 4262a in the second actuation unit 4262 is fixed relative to the base 421 can be the same as the way the first fixing member 4261a is fixed relative to the base 421. The way the fourth fixing member 4262b connects to the third side plate 422b2 and the fourth side plate 422b3 can be the same as the way the second fixing member 4261b connects to the first side plate 422a2, and will not be described in detail here.

[0188] Based on any of the above embodiments, please refer to Figure 8 and combined Figure 9a The camera driving assembly 42 also includes a first reset member 4201, with its two ends connected to the base 421 and the first seat 422a, respectively. The first reset member 4201 is used to apply a force to the first seat 422a to reset it after the first actuation assembly 426a drives the first seat 422a to move relative to the base 421. The first reset member 4201 can be an elastic structural member. For example, the first reset member 4201 can be a spring or a bellows, etc. The first reset member 4201 can provide a force parallel to the XY plane to the first seat 422a.

[0189] Thus, when the first actuation wire 4261c is energized and contracts, it applies a first force along the first direction e1, pointing from the second fixing member 4261b to the first fixing member 4261a, to the first seat 422a, allowing the first seat 422a to move relative to the base 421. During this process, the first reset member 4201 undergoes elastic deformation, and the first actuation wire 4261c deforms against the force of the first reset member 4201 and the friction between the first seat 422a and the base 421, changing from a first form to a second form. Therefore, in the process of achieving anti-shake, the first reset member 4201 can balance and buffer the force on the first seat 422a, making the movement of the first seat 422a more stable.

[0190] When the first actuation line 4261c is de-energized and cooled, the first force exerted by the first actuation line 4261c on the first seat 422a disappears. At this time, the first seat 422a can be reset under the force provided by the first reset member 4201, returning to its initial position. As the first seat 422a resets, it can drive the second fixing member 4261b to move relative to the first fixing member 4261a, allowing the first actuation line 4261c to quickly return to its first form. Here, "the initial position of the first seat 422a" refers to the position of the first seat 422a when the first actuation line 4261c is in the first form.

[0191] In some embodiments, the first reset member 4201 may be disposed on the circumferential outer side of the first base 422a. See also... Figure 8 One or more first reset members 4201 may be provided on the side of the first side plate 422a2 facing away from the second side plate 422a3 (that is, the outer side of the first side plate 422a2), and one or more first reset members 4201 may be provided on the side of the second side plate 422a3 facing away from the first side plate 422a2 (that is, the outer side of the second side plate 422a3).

[0192] Please see Figure 9b The first reset member 4201 located outside the first side plate 422a2 and the first actuation unit 4261 located outside the first side plate 422a2 are in a direction parallel to the optical axis (that is, Figure 9b The first reset member 4201 located outside the second side plate 422a3 and the first actuation unit 4261 located outside the second side plate 422a3 can also be arranged in a direction parallel to the optical axis.

[0193] In this way, the space on the outer periphery of the first base 422a can be fully utilized, and the superposition size of the first reset member 4201 and the first base 422a in the optical axis direction can be reduced, thereby reducing the overall volume of the camera driving assembly 42 and realizing the miniaturization design of the camera driving assembly 42.

[0194] When multiple first reset members 4201 are provided on the outer side of the first side plate 422a2, the multiple first reset members 4201 on the outer side of the first side plate 422a2 can be arranged in the circumferential direction of the first base 422a or in the optical axis direction of the lens 41. The arrangement of the multiple first reset members 4201 on the outer side of the second side plate 422a3 can be the same as the arrangement of the multiple first reset members 4201 on the outer side of the first side plate 422a2.

[0195] For further details, please refer to Figure 9bThe first reset member 4201 on the outer side of the first side plate 422a2 is located on the side of the first actuation unit 4261 on the outer side of the first side plate 422a2 away from the base 421. In this way, interference between the first actuation line 4261c and the first reset member 4201 can be avoided when the first actuation line 4261c is de-energized and sags, thereby improving the operational reliability of the camera drive assembly 42.

[0196] Of course, it is understood that in other embodiments, the first reset member 4201 may also be disposed on the end face of the first seat 422a facing away from the base 421. That is, the first reset member 4201 may be disposed on the top of the first seat 422a.

[0197] In some embodiments, please refer to Figure 9b The first reset member 4201 includes a first connecting portion 4201a, a second connecting portion 4201b, and an elastic deformation portion 4201c, with the elastic deformation portion 4201c connected between the first connecting portion 4201a and the second connecting portion 4201b. The first connecting portion 4201a is fixedly connected to the base 421, and the second connecting portion 4201b is fixedly connected to the first seat body 422a.

[0198] Specifically, the first connecting part 4201a can be fixedly connected to the base 421 via the first fixing boss 429. The second connecting part 4201b can be fixedly connected to the first side plate 422a2 or the second side plate 422a3. For example, the second connecting part 4201b can be fixedly connected to the first fixing area n1 of the first side plate 422a2.

[0199] In some embodiments, the extension and retraction direction of the first reset member 4201 is parallel to the XY plane. For example, the extension and retraction direction of the first reset member 4201 is parallel to the first direction e1. That is, the extension and retraction direction of the elastic deformation portion 4201c is parallel to the first direction e1. In this way, after the first reset member 4201 deforms, it can avoid generating any force other than the first direction e1, ensuring that the elastic deformation portion 4201c only provides the first seat 422a with a force extending along the first direction e1. This prevents the first seat 422a from shaking during the reset process, allowing the first seat 422a to reset smoothly.

[0200] For further details, please refer to Figure 8 and combined Figure 9b The camera module 40 also includes a second reset member 4202, which is connected to the second seat 422b and the base 421. The second reset member 4202 is used to apply a force to the second seat 422b to reset it after the second actuation assembly 426b drives the second seat 422b to move relative to the first seat 422a. The second reset member 4202 can provide a force parallel to the XY plane to the second seat 422b.

[0201] The second reset member 4202 can be an elastic structural member. For example, the second reset member 4202 can be a spring or a bellows, etc.

[0202] Please see Figure 8 The second reset member 4202 can be disposed on the circumferential outer side of the second base 422b. Specifically, one or more second reset members 4202 can be disposed on the outer side of the third side plate 422b2 and the fourth side plate 422b3. Alternatively, the second reset member 4202 can also be disposed on the side of the second base 422b facing away from the base 421.

[0203] The structure and working principle of the second reset member 4202 can be the same as those of the first reset member 4201. The positional relationship between the second reset member 4202 and the second actuation line 4262c can be designed with reference to the positional relationship between the first reset member 4201 and the first actuation line 4261c. The way in which the second reset member 4202 connects to the base 421 and the second seat 422b can be designed with reference to the way the first reset member 4201 connects to the base 421 and the first seat 422a. Further details will not be provided here.

[0204] Based on any of the above embodiments, please refer to Figure 13 , Figure 13 for Figure 9a The image shows a side view of the camera driver assembly 42. Among them, Figure 13 The side view shown is a schematic diagram of the view from the first side plate 422a2 to the second side plate 422a3.

[0205] When the first actuation line 4261c is not energized, that is, when the first actuation line 4261c is in the first configuration, the vertical distance between the first end A of the first actuation line 4261c (that is, the end of the first actuation line 4261c that is fixed relative to the base 421) and the reference plane m is equal to the vertical distance between the second end B of the first actuation line 4261c (that is, the end of the first actuation line 4261c that is fixed relative to the first seat 422a) and the reference plane m. In this case, the line connecting the first end A and the second end B is parallel to the XY plane. Specifically, the line connecting the first end A and the second end B can be parallel to the first direction e1.

[0206] The reference plane m is perpendicular to the optical axis of the lens 41, and is located on the side of the first actuation line 4261c closest to the base 421. That is, the reference plane m is parallel to the XY plane. The two first actuation lines 4261c of the two first actuation units 4261 have the same angle with the XY plane.

[0207] For details, please refer to Figure 13The distance between the first end A of the first actuation line 4261c and the reference plane m is the first distance d1, and the distance between the second end B of the first actuation line 4261c and the reference plane m is the second distance d2. The first distance d1 can be equal to the second distance d2.

[0208] In this way, on the one hand, when the first actuation line 4261c is energized and retracts, the first actuation line 4261c can apply a force along the first direction e1 to the first base 422a, so that the first base 422a and the carrier 423 carrying the lens 41 can move along the first direction e1 to achieve optical image stabilization; on the other hand, it can reduce the space occupied by the first actuation unit 4261 in the Z-axis direction, which is conducive to reducing the height of the camera driving component 42 and the camera module 40. Thus, when the camera driving component 42 is applied to the electronic device 100, it is conducive to reducing the thickness of the electronic device 100 and realizing the thin and light design of the electronic device 100.

[0209] Furthermore, since the connection between the first end A and the second end B is parallel to the XY plane when the first actuation line 4261c is not energized, the force generated after the first actuation line 4261c is energized does not have a component force along the optical axis of the lens 41. This can prevent the first mount 422a from moving away from the base 421 along the optical axis during the image stabilization process. This can further improve the stability of the first mount 422a moving relative to the base 421 along the first direction e1, and can also prevent the image stabilization process from interfering with the focusing process. This not only helps to improve the accuracy of image stabilization compensation motion and focusing accuracy, but also improves the clarity of the images captured by the camera module 40. It can also make the image stabilization process and the focusing process independent of each other, so as to achieve accurate focusing while achieving accurate image stabilization.

[0210] When the second actuation line 4262c is not energized, the line connecting the two ends of the third fixing member 4262a and the fourth fixing member 4262b can also be parallel to the XY plane. For example, the line connecting the two ends of the second actuation line 4262c is parallel to the second direction e2. The two second actuation lines 4262c of the two second actuation units 4262 have the same angle with the XY plane.

[0211] Please see Figure 14 and combined Figure 15 , Figure 14 for Figure 12 The image shows a cross-sectional view of the camera driver assembly 42 at the CC line. Figure 15 for Figure 12The image shows a cross-sectional view of the camera driving assembly 42 at line DD. A first guide groove C31 is provided between the base 421 and the first seat 422a, and a first guide member C32 is provided within the first guide groove C31. The first guide groove C31 extends along a first direction e1. When the first seat 422a moves relative to the base 421 along the first direction e1, the first guide member C32 moves relative to the first guide groove C31 in the first direction e1. For example, the base 421, the first guide member C32, and the first seat 422a are arranged sequentially along the optical axis of the lens 41.

[0212] In this way, the first guide member C32 can restrict and guide the movement direction of the first seat 422a relative to the base 421, ensuring that the first seat 422a can move linearly relative to the base 421 along the first direction e1, avoiding deviation of the movement direction of the first seat 422a, thereby improving the stability of the movement of the first seat 422a relative to the base 421, and reducing the deviation between the target position and the actual position of the first seat 422a during the anti-shake process, thereby improving the control accuracy of the anti-shake compensation motion.

[0213] Please see Figures 14-15 In this embodiment, a portion of the first guide groove C31 is formed on the base 421, and another portion is formed on the first seat 422a. It is understood that in other embodiments, the entire first guide groove C31 may be formed on the base 421, or the entire first guide groove C31 may be formed on the first seat 422a.

[0214] To further improve the stability of the movement of the first seat 422a relative to the base 421, in some embodiments, please refer to... Figure 16 , Figure 16 for Figure 12 The image shows a top view of the base 421 and the first guide C32 in the camera driving assembly 42. Multiple first guide grooves C31 are arranged at circumferential intervals along the base 421. For an example, please refer to... Figure 16 There can be four first guide grooves C31, which can be respectively set at the four corners of the base 421. The depth of the multiple first guide grooves C31 in the optical axis direction of the lens 41 can be the same.

[0215] In some embodiments, please refer to Figure 16The first guide member C32 is a ball bearing. One or more balls bearings can be installed in each first guide groove C31. The size of the balls in different first guide grooves C31 can be the same. When the first seat 422a moves relative to the base 421 along the first direction e1, the balls can roll within the first guide groove C31 along the first direction e1. This not only guides the movement direction of the first seat 422a through the first guide member C32, but also reduces the friction between the first seat 422a and the base 421, thereby reducing the deviation between the target position and the actual movement position of the first seat 422a during image stabilization. This improves the control accuracy of the image stabilization process, thereby reducing the amount of lens shake and improving the shooting effect.

[0216] It is understood that in other embodiments, the first guide member C32 may also be a guide rod extending along the first direction e1. In this case, the first guide member C32 may be fixedly connected to one of the base 421 and the first seat 422a, and at least a portion of the first guide groove C31 is formed on the other of the first seat 422a and the base 421. When the first seat 422a moves relative to the base 421 along the first direction e1, the first guide member C32 and the first guide groove C31 can move relative to each other in the first direction e1.

[0217] Please continue reading. Figures 14-15 A second guide groove C41 is provided between the first seat 422a and the second seat 422b, and a second guide member C42 is provided within the second guide groove C41. The second guide groove C41 extends along the second direction e2. Specifically, the first seat 422a, the second guide member C42, and the second seat 422b are arranged sequentially along the optical axis of the lens 41. When the second seat 422b moves relative to the first seat 422a along the second direction e2, the second guide member C42 and the second guide groove C41 move relative to each other in the second direction e2.

[0218] In this way, the movement direction of the second seat 422b relative to the first seat 422a can be restricted and guided by the second guide member C42, ensuring that the second seat 422b can move linearly relative to the first seat 422a along the second direction e2, avoiding deviation of the movement direction of the second seat 422b, thereby improving the stability of the movement of the second seat 422b relative to the first seat 422a, and reducing the deviation between the target position and the actual position of the second seat 422b during the anti-shake process, thereby improving the control accuracy of the anti-shake compensation motion.

[0219] Please see Figure 17 , Figure 17 for Figure 12The image shows a top view of the base 421, the first seat 422a, and the second guide C42 in the camera driving assembly 42. Multiple second guide grooves C41 are arranged at intervals along the circumference of the first seat 422a. For example, there may be four second guide grooves C41, which may be respectively located at the four corners of the first seat 422a. The depth of the multiple second guide grooves C41 along the optical axis of the lens 41 may be the same.

[0220] The structure of the second guide component C42 can be designed with reference to the structure of the first guide component C32. Specifically, the second guide component C42 can also be a ball bearing or a guide rod.

[0221] When the second guide member C42 is a ball bearing, the ball bearing can roll along the second direction e2 within the second guide groove C41. In this case, when the first guide member C32 is also a ball bearing, a double-layer ball bearing structure can be formed, which can greatly reduce the friction during the image stabilization process, thereby reducing the amount of lens shake 41 and improving the shooting effect.

[0222] When the second guide member C42 is a guide rod, it is fixedly connected to one of the first seat 422a and the second seat 422b, and at least a portion of the second guide groove C41 is formed on the other of the first seat 422a and the second seat 422b. When the second seat 422b moves relative to the first seat 422a along the second direction e2, the second guide member C42 and the second guide groove C41 can move relative to each other in the second direction e2.

[0223] In some embodiments, to reduce the risk of tilting of the first mount 422a and the second mount 422b during image stabilization, please refer to... Figures 18-19 , Figure 18 for Figure 7 The cross-sectional view of the 42-piece camera driver assembly shown at line EE is shown. Figure 19 for Figure 18 An enlarged view of region A in the sectional view shown.

[0224] The camera driving assembly 42 also includes a magnetic assembly C2, which includes a first magnetic element C21 and a second magnetic element C22. The first magnetic element C21 is disposed on the second base 422b, and the second magnetic element C22 is disposed on the base 421. The first magnetic element C21 and the second magnetic element C22 are magnetically attracted to each other. The arrangement direction of the first magnetic element C21 and the second magnetic element C22 can be parallel to the optical axis of the lens 41.

[0225] Specifically, the first magnetic attractor C21 and the second magnetic attractor C22 are arranged in the Z-axis direction. The first magnetic attractor C21 can be fixed to at least one of the second support plate 422b1, the third side plate 422b2, and the fourth side plate 422b3. One of the first magnetic attractor C21 and the second magnetic attractor C22 can be a magnet, and the other can be a magnetic metal part (e.g., an iron part, a stainless steel part, etc.) that magnetically engages with the magnet, or both the first magnetic attractor C21 and the second magnetic attractor C22 can be magnets.

[0226] Thus, when the second seat 422b moves relative to the first seat 422a along the second direction e2, the magnetic attraction component C2 generates a magnetic attraction force between the base 421 and the second seat 422b. Using this magnetic attraction force, the second seat 422b can be made to tend towards the base 421 during the movement process. In this way, the probability of the moving second seat 422b tilting can be reduced, thereby improving the stability of the movement of the second seat 422b during the anti-shake process and helping to improve the control accuracy of the anti-shake process.

[0227] Meanwhile, since a portion of the second seat 422b is located on the side of the first seat 422a facing away from the base 421, that is, a portion of the first seat 422a is sandwiched between the second seat 422b and the base 421, for example, in Figure 19 In the embodiment shown, the first support plate 422a1 of the first base 422a is sandwiched between the second support plate 422b1 of the second base 422b and the base 421.

[0228] Therefore, when the first seat 422a moves relative to the base 421 along the first direction e1, the magnetic attraction component C2 generates a magnetic attraction force between the base 421 and the second seat 422b, which also causes the first seat 422a to tend to move towards the base 421 during the movement. In this way, no additional magnetic attraction structure is needed between the first seat 422a and the base 421, which reduces the probability of the moving first seat 422a tilting. This not only improves the stability of the first seat 422a during the image stabilization process, which is conducive to further improving the control accuracy of the image stabilization process, but also reduces the number of structural components of the camera driver assembly 42, simplifies the structure of the camera driver assembly 42, further reduces the overall size of the camera driver assembly 42, and improves the assembly efficiency of the camera driver assembly 42.

[0229] In some embodiments, to enhance the magnetic attraction between the second magnetic member C22 and the first magnetic member C21, please refer to... Figure 19 The surface of the second magnetic attractor C22 facing the first base 422a is exposed on the base 421.

[0230] To enable the autofocus function of camera module 40, please refer to [link / reference]. Figure 20 , Figure 20 for Figure 9a The diagram shows the assembly of the camera drive assembly 42 and the lens 41. The camera drive assembly 42 also includes a focusing drive unit 425. The focusing drive unit 425 is used to drive the carrier 423 to move relative to the second base 422b along the axial direction of the lens mounting hole 423a (that is, the optical axis O1 direction of the lens 41). Since the lens 41 is fixedly connected to the carrier 423, under the drive of the focusing drive unit 425, when the carrier 423 moves relative to the second base 422b along the optical axis O1 of the lens 41, the lens 41 inside the carrier 423 can be moved simultaneously along the optical axis O1 of the lens 41.

[0231] In this way, driven by the focusing drive unit 425, the imaging distance between the lens 41 and the image sensor 442 can be changed, so that a clear image can be obtained on the image sensor 442 when shooting objects at different imaging distances, thus achieving autofocus. Furthermore, the focusing function of the camera module 40 is achieved by moving the drive carrier 423 relative to the second base 422b, resulting in a small load on the focusing drive unit 425 and a smaller size. Moreover, in this camera drive assembly 42, the second base 422b can serve not only as a fixed part for autofocus but also as a moving part for optical image stabilization, simplifying the structure of the camera drive assembly 42, reducing its overall size, and facilitating miniaturization.

[0232] There can be one or more focus drive units 425. When there are multiple focus drive units 425, they can be arranged at intervals in the circumferential direction of the carrier 423. For example, see [link to relevant documentation]. Figure 20 There can be two focusing drive units 425, which are arranged opposite to each other. For example, the two focusing drive units 425 can be symmetrically arranged about the optical axis O1 of the lens 41. In this way, not only can the overall driving force of the focusing drive unit 425 on the carrier 423 be improved, but also the uniformity of the force on the carrier 423 can be improved. This can improve the stability of the movement of the carrier 423 during autofocus, which is beneficial to improving focusing accuracy and the image clarity of the camera module 40.

[0233] In some embodiments, the focusing drive unit 425 may be a voice coil motor (VCM). See also... Figure 20 and combined Figure 21 , Figure 21 for Figure 9aThe image shows an exploded view of the carrier 423, the second base 422, and the focus drive unit 425 in the camera drive assembly 42. The focus drive unit 425 includes a first magnet 4251 and a coil 4252. The first magnet 4251 can be a magnet or a magnetic steel. The coil 4252 can be made of wire. The arrangement direction of the first magnet 4251 and the coil 4252 can be perpendicular to the optical axis O1 of the lens 41. For example, the first magnet 4251 and the coil 4252 can be arranged along the X-axis direction.

[0234] In some embodiments, the first magnet 4251 may be disposed on the second base 422b, and the coil 4252 may be disposed on the carrier 423. In this case, the coil 4252 can move relative to the second base 422b along with the carrier 423. It is understood that in other embodiments of this application, the first magnet 4251 may also be disposed on the carrier 423, and the coil 4252 may be disposed on the second base 422b. In this case, the first magnet 4251 can move relative to the second base 422b along with the carrier 423. It is sufficient that one of the first magnet 4251 and the coil 4252 is disposed on the second base 422b and the other on the carrier 423.

[0235] In this way, when the coil 4252 is energized, the coil 4252 can drive the carrier 423 to move relative to the second base 422b under the action of the magnetic field provided by the first magnet 4251, so that the carrier 423 can carry the lens 41 to move along the optical axis O1 to achieve autofocus.

[0236] However, the structure of the focusing drive unit 425 is not limited to this. In other embodiments, the focusing drive unit 425 can also be an SMA drive unit, as long as it can drive the carrier 423 to move relative to the second seat 422b along the optical axis.

[0237] In some embodiments, to increase the driving force of a single focus drive unit 425 on the carrier 423, please refer to... Figure 21 The first magnet 4251 includes a first magnetic part 4251a, a second magnetic part 4251b, and a third magnetic part 4251c. These three magnetic parts are arranged in a Halebeck array to concentrate the magnetic force of the first magnet 4251 towards the coil 4252. The Halebeck array is a permanent magnet arrangement where permanent magnets with different magnetization directions are arranged in a specific order, resulting in a significantly stronger magnetic field on one side of the Halebeck array and a significantly weaker magnetic field on the other side.

[0238] In this way, the magnetic force of the first magnet 4251 can be concentrated towards the coil 4252, thereby increasing the driving force of the focusing drive unit 425 on the carrier 423, and thus balancing the size and driving force of the first magnet 4251.

[0239] In some embodiments, please refer to Figure 20 and combined Figure 21 There are two first magnets 4251, which can be fixedly connected to the third side plate 422b2 and the fourth side plate 422b3 respectively. For example, the third side plate 422b2 and the fourth side plate 422b3 are each provided with a first mounting groove C1, and the first magnets 4251 can be disposed within the first mounting groove C1. The first magnets 4251 can be fixedly connected to the first mounting groove C1 by means of snap-fit, adhesive, screw connection, etc. This reduces the combined size of the first magnets 4251 and the second base 422b, which helps to reduce the overall volume of the camera driving assembly 42, and thus facilitates the miniaturization design of the camera module 40.

[0240] It is understood that in an embodiment where the coil 4252 is disposed in the second base 422b, the coil 4252 may be disposed in the first mounting slot C1.

[0241] In some embodiments, the first magnet 4251 in the focusing drive unit 425 can be used as the first magnetic attractor C21. In this case, the first magnet 4251 is disposed on the second base 422b, and the coil 4252 is disposed on the carrier 423. The first magnet 4251 can magnetically engage with the second magnetic attractor C22 and can also engage with the coil 4252 to drive the carrier 423 to move. In this way, there is no need to additionally provide other magnets on the second base 422b to magnetically engage with the second magnetic attractor C22, which can reduce the number of structural components of the camera drive assembly 42, simplify the structure of the camera drive assembly 42, and reduce the overall size of the camera drive assembly 42. In addition, it can also avoid the magnetic field generated by the other magnets disposed on the second base 422b from interfering with the coil 4252 in the focusing drive unit 425, thereby improving the focusing accuracy of the camera module 40.

[0242] Building upon this, to further reduce the magnetic interference caused by the magnetic attraction component C2 to the focusing drive unit 425, the second magnetic attraction component C22 is made of metal. When there are multiple first magnets 4251, all of them can magnetically engage with the second magnetic attraction component C22. This increases the magnetic attraction force of the second magnetic attraction component C2, further improving the stability of the movement of the second base 422b relative to the first base 422a, and the stability of the movement of the first base 422a relative to the base 421. This helps to further reduce camera shake and optimize the quality of the captured image.

[0243] To improve the stability of the movement of the carrier 423 relative to the second base 422b during autofocus, please refer to... Figures 20-21 The camera driving assembly 42 may further include a sliding assembly 427, which includes a slider 4271 and a groove 4272. The slider 4271 may be fixedly connected to the second base 422b, and the groove 4272 is formed in the carrier 423. Alternatively, in some other embodiments, the slider 4271 may also be fixedly connected to the carrier 423, in which case the groove 4272 is formed in the second base 422b.

[0244] Since the carrier 423 and the second seat 422b do not move relative to each other in the XY plane, by setting the sliding component 427 between the carrier 423 and the second seat 422b, the fitting accuracy of the sliding member 4271 and the sliding groove 4272 in the sliding component 427 can be improved, thereby ensuring the guiding and limiting function of the sliding component 427.

[0245] Please see Figure 20 and combined Figure 21 The slider 4271 is elongated. For example, the slider 4271 may be cylindrical. The axial direction of the slider 4271 is parallel to the optical axis of the lens 41. When the carrier 423 moves relative to the second seat 422b along the optical axis of the lens 41, the slider 4271 slides into the groove 4272. In some embodiments, at least a portion of the outer peripheral surface of the slider 4271 may abut against the groove wall of the groove 4272.

[0246] In this way, during the autofocus process, the movement direction of the carrier 423 can be restricted and guided by the cooperation of the slider 4271 and the slide groove 4272, ensuring that the carrier 423 can move linearly relative to the second seat 422b along the optical axis, avoiding deviation of the movement direction of the carrier 423, thereby improving the stability of the movement of the carrier 423 relative to the seat and preventing the carrier 423 from shaking during the autofocus process.

[0247] In order to further improve the stability of the carrier 423 moving relative to the base during autofocus, there are multiple sliding components 427, which can be arranged at intervals in the circumferential direction of the carrier 423.

[0248] In some embodiments, please refer to Figure 20The camera driving assembly 42 also includes an elastic element 4203. The two ends of the elastic element 4203 are respectively connected to the carrier 423 and the second base 422b. The elastic element 4203 can be located on the side of the second base 422b facing away from the base 421. When the carrier 423 moves relative to the second base 422b along the optical axis, the elastic element 4203 can deform, thereby balancing and buffering the force on the carrier 423, making the movement of the carrier 423 more stable.

[0249] For example, there are multiple elastic elements 4203, which are arranged at intervals along the circumference of the carrier 423. For instance, the multiple elastic elements 4203 can be symmetrically arranged about the optical axis O1 of the lens 41. In this way, when the lens 41 and the carrier 423 move along the optical axis O1 of the lens 41, the multiple elastic elements 4203 can generate the same deformation, providing symmetrical elastic force, thereby further improving the stability of the carrier 423 relative to the seat.

[0250] In some embodiments, the elastic element 4203 can be an electrical connector. In this case, the elastic element 4203 is electrically connected to the coil 4252, and simultaneously electrically connected to the circuit board 441 of the camera module 40. For example, a conductive structure can be provided on the second housing 422b to achieve the electrical connection between the elastic element 4203 and the circuit board 441.

[0251] The conductive structure can be implemented in various ways. For example, the conductive structure can be a conductive lead formed by electroplating. Alternatively, the conductive structure can be formed by embedding metal through insert molding. In this way, the elastic element 4203 not only buffers and balances the stability of the carrier 423's movement, but also provides electrical connection.

[0252] Furthermore, the elastic element 4203 can also be electrically connected to the drive structure of the variable aperture 43, thereby allowing the signal of the variable aperture 43 to be output to the circuit board 441 through the elastic element 4203. This enables the variable aperture 43 and the focus drive unit 425 to share an electrical connector, achieving electrical connection with the circuit board 441. This simplifies the structure of the camera drive assembly 42.

[0253] It is understood that in embodiments where the camera driving assembly 42 does not include the variable aperture 43, the elastic element 4203 may be a non-electrical connector, or the camera driving assembly 42 may not include the elastic element 4203. In this case, the first magnet 4251 may be disposed on the carrier 423, and the coil 4252 may be disposed on the second base 422b. The coil 4252 may be electrically connected to the circuit board 441 of the camera module 40 through the aforementioned conductive structure within the second base 422b.

[0254] In some embodiments, please refer to Figure 21 The camera driving assembly 42 also includes a first metal piece 4281, which is used to magnetically engage with a first magnet 4251. One of the first metal piece 4281 and the first magnet 4251 is disposed on the carrier 423, and the other is disposed on the second base 422b. For example, the first metal piece 4281 can be an iron sheet, a magnetically conductive steel sheet, etc. The arrangement direction of the first metal piece 4281 and the first magnet 4251 is perpendicular to the optical axis O1 of the lens 41.

[0255] In this way, the first magnet 4251 can generate a magnetic attraction force on the first metal part 4281. Under the action of this magnetic attraction force, the carrier 423 tends to move towards the second base 422b as it moves relative to the second base 422b along the optical axis O1 of the lens 41. This allows the sliding member 4271 to remain in contact with the slide groove 4272, which can improve the guiding and restricting effect of the sliding component 427 on the carrier 423. This can further improve the stability of the carrier 423's movement relative to the second base 422b during autofocus.

[0256] In addition, since both the first metal part 4281 and the coil 4252 can cooperate with the first magnet 4251, that is, the first metal part 4281 and the coil 4252 can reuse the first magnet 4251 in the focusing drive unit 425, there is no need to set up other magnets to cooperate with the first metal part 4281. This can avoid the magnetic field generated by other magnets from interfering with the coil 4252, thereby improving the focusing accuracy of the camera module 40, reducing the number of structural parts, simplifying the structure of the camera drive assembly 42, and thus helping to reduce the overall volume of the camera drive assembly 42 and realize the miniaturization design of the camera drive assembly 42.

[0257] In some embodiments, please refer to Figure 19 The first metal component 4281 can be located on the side of the coil 4252 opposite to the first magnet 4251. To reduce the combined size of the first metal component 4281 and the carrier 423, the first metal component 4281 can be embedded within the carrier 423. For example, the first metal component 4281 and the carrier 423 can be connected by means of bonding, snap-fitting, screw connection, insert molding, etc.

[0258] To enhance the magnetic attraction between the first metal component 4281 and the first magnet 4251, at least a portion of the surface of the first metal component 4281 facing the first magnet 4251 is exposed to the carrier 423. Specifically, the entire surface of the first metal component 4281 facing the first magnet 4251 is exposed to the carrier 423, or a portion of the surface of the first metal component 4281 facing the first magnet 4251 is exposed to the carrier 423.

[0259] In some embodiments, this is to enable electrical connections between the first actuation component 426a, the second actuation component 426b, the focus drive unit 425, the variable aperture 43, etc., and the circuit board 441. (See also...) Figure 19 The camera driver assembly 42 also includes a first electrical connection structure 4204, which can be embedded in the base 421.

[0260] Please see Figure 22 , Figure 22 for Figure 9a The exploded view shows the base 421 and the first electrical connection structure 4204 in the camera driver assembly 42. The first electrical connection structure 4204 may have multiple pins 4204a, and can be electrically connected to the circuit board 441 through the multiple pins 4204a.

[0261] In some embodiments, the first electrical connection structure 4204 can be a metal plate. In this case, the first electrical connection structure 4204 can be reused as the second magnetic member C22. That is, the second magnetic member C22 can be used to magnetically engage with the first magnetic member C21, and can also be used to realize the electrical connection between the image stabilization drive unit 426, the focus drive unit 425, the variable aperture 43, etc., and the circuit board 441. In this way, the number of structural components of the camera drive assembly 42 can be reduced, and the structure of the camera drive assembly 42 can be simplified.

[0262] In some embodiments, to achieve electrical connection between the first actuation unit 4261 and the circuit board 441, a first flexible electrical connector is provided on the surface of the first reset member 4201. The first flexible electrical connector is electrically connected to the first electrical connection structure 4204 and to the first actuation unit 4261. For example, the first flexible electrical connector can be a flexible circuit board. The shape of the first flexible electrical connector can be the same as the shape of the first reset member 4201. In this way, the signal of the first actuation line 4261c can be conducted to the circuit board 441 through the first flexible electrical connector, and the structure is simple and ingeniously designed.

[0263] It is understood that in other embodiments, a plurality of first reset members 4201 may be provided on the outer side of the first side plate 422a2, and the electrical connection between the first actuation unit 4261 and the first electrical connection structure 4204 may be realized through the plurality of first reset members 4201.

[0264] The electrical connection between the second actuation unit 4262 and the circuit board 441 can be designed with reference to the electrical connection between the first actuation unit 4261 and the circuit board 441, and will not be described in detail here.

[0265] In some other embodiments, please refer to Figure 23 , Figure 23 This is a side view showing the assembly of a camera driver assembly 42 and a lens 41 provided in other embodiments of this application. The camera driver assembly 42 and lens 41 in this embodiment... Figure 9a The difference in the camera driving component 42 shown is that the first actuation line 4261c in this embodiment is not parallel to the XY plane.

[0266] For details, please refer to Figure 23 When the first actuation line 4261c is in the first state, that is, when the first actuation line 4261c is not energized, the vertical distance d1 between the first end A of the first actuation line 4261c and the reference plane m is less than the vertical distance d2 between the second end B of the first actuation line 4261c and the reference plane m. Specifically, in the direction parallel to the optical axis O1 of the lens 41, the second end B is located on the side of the first end A away from the base 421.

[0267] Please see Figure 24 , Figure 24 for Figure 23 The diagram shows the change of the first actuation line 4261c in the camera driver assembly 42 between a first and a second configuration. For ease of distinction, in... Figure 24 The first actuation line 4261c in the first state (i.e., the first actuation line 4261c in the uncontracted state) is represented by a dashed line, and the first actuation line 4261c in the second state (i.e., the first actuation line 4261c after contraction) is represented by a solid line. When the first actuation line 4261c is in the first state, the line connecting the first end A and the second end B can form the hypotenuse of a right triangle ABH. When the first actuation line 4261c is in the second state, the line connecting the first end A and the second end B can form the hypotenuse of a right triangle AB'F.

[0268] In right triangle ABH, the hypotenuse is 'a', leg AH is 'b', and leg BH is 'c'. In right triangle AB'F, the hypotenuse is 'a1', leg AF is 'b1', and leg B'F is 'c'.

[0269] The following example illustrates the stroke generated by the first actuation component 426a, assuming the unshrunken length 'a' of the first actuation line 4261c is 10 mm, the length decreases by 1% after thermal shrinkage, and the angle θ between the first actuation line 4261c and the XY plane is 15° when the first actuation line 4261c is unshrunken. It should be noted that the above values ​​do not constitute a limitation on the structural dimensions of the first actuation component 426a.

[0270] The calculation process for the stroke Δb of the first moving component 426a can be as follows:

[0271] c=a*sinθ=10*sin15°=2.5882mm;

[0272] a1=a*(1-1%)=10*0.99=9.9mm;

[0273]

[0274] △b=b-b1=0.1036mm≈104μm;

[0275] △b / b=0.1036 / 9.6593≈1.1%.

[0276] As can be seen from the above calculation results, when the second end B of the first actuation line 4261c is set on the side away from the base 421 of the first end A, that is, when the first actuation line 4261c is tilted relative to the XY plane, when the length of the first actuation line 4261c shrinks by 0.1mm, the stroke Δb of the first actuation component 426a is 0.1036mm, which is about 104μm. The stroke of the first actuation component 426a is greater than the actual shrinkage length of the first actuation line 4261c.

[0277] In this way, a smaller contraction of the first actuation line 4261c allows the first actuation component 426a to achieve a larger stabilization stroke Δb. This provides a wider stabilization compensation range within the linear contraction zone of the first actuation line 4261c, which not only alleviates the limitation of optical image stabilization technology by the linear contraction zone of the first actuation line 4261c, but also reduces the space occupied by the first actuation line 4261c in the circumferential direction of the first base 422a. This reduces the width and / or length of the camera drive component 42 and the camera module 40, facilitating the assembly of the camera module 40 within the electronic device 100. Furthermore, under the same stabilization stroke, the smaller contraction of the first actuation line 4261c in this embodiment shortens the contraction time, improving the stabilization efficiency and effect of the stabilization drive component 426, and ultimately significantly improving the shooting quality of the camera module 40.

[0278] Furthermore, by setting the second end B of the first actuation line 4261c on the side of the first end A away from the base 421, that is, the second end B is further away from the base 421 than the first end A, the force generated by the first actuation line 4261c after being energized has a component force parallel to the optical axis O1 of the lens 41 and pointing from the first seat body 422a towards the base 421. This component force can pull the first seat body 422a to move towards the base 421 along the optical axis O1, so that the first seat body 422a can press against the base 421 during the image stabilization process. Therefore, the first mount 422a can be prevented from moving away from the base 421 along the optical axis O1 during the image stabilization process. This improves the stability of the first mount 422a's movement relative to the base 421 along the XY plane and prevents the image stabilization process from interfering with the focusing process. This not only helps improve the accuracy of the image stabilization compensation motion and the focusing accuracy, but also improves the clarity of the images captured by the camera module 40. Furthermore, it makes the image stabilization process and the focusing process independent of each other, thus achieving accurate focusing while achieving accurate image stabilization.

[0279] In some embodiments, when the first actuation line 4261c is not energized, the angle between the line connecting the first end A and the second end B of the first actuation line 4261c and the XY plane is less than or equal to 30 degrees. For example, when the first actuation line 4261c is not energized, the angle between the line connecting the first end A and the second end B of the first actuation line 4261c and the XY plane can be 30 degrees, 28 degrees, 26 degrees, 24 degrees, 22 degrees, 20 degrees, 18 degrees, 15 degrees, 12 degrees, 10 degrees, 8 degrees, 6 degrees, 4 degrees, 2 degrees, 1 degree, etc. This allows for a larger anti-shake compensation range while reducing the space occupied by the anti-shake drive component 426.

[0280] It is understood that the arrangement of the first actuation line 4261c in this embodiment can be applied to the camera driver component 42 in any embodiment of this application. Furthermore, the arrangement of the second actuation line 4262c in this embodiment can be the same as the arrangement of the first actuation line 4261c in this embodiment, or it can be... Figure 9a The arrangement of the first actuation line 4261c in the camera driving assembly 42 in the illustrated embodiment is the same. It is sufficient to ensure that the included angles between the two relatively opposite second actuation lines 4262c and the XY plane are equal.

[0281] Other structures of the camera driver component 42 in this application embodiment can be designed with reference to the camera driver component 42 in any of the above embodiments, and will not be described in detail here.

[0282] Based on the descriptions of the above embodiments, when the camera driving component 42 in the embodiments of this application is applied to the camera module 40 and the electronic device 100, the control accuracy of the image stabilization process of the camera module 40 can be effectively improved, the control difficulty of the image stabilization process can be reduced, and the energy consumption of the camera driving component 42 can be reduced. Furthermore, the image stabilization driver 426 in the embodiments of this application is small in size and has a large driving force, which can solve the problem of the voice coil motor being limited by power consumption and unable to significantly increase the driving force in related technologies. This broadens the application range of the camera driving component 42, enabling it to meet the driving requirements of heavy (mass greater than or equal to 500mg) camera modules 40. Simultaneously, it avoids magnetic interference between the image stabilization driver 426 and the focusing drive unit 425, thereby improving the focusing accuracy and image stabilization accuracy of the camera driving component 42. In addition, it can reduce the interference of signals on the actuator line to the image sensor 442, thereby improving the shooting quality of the camera module 40.

[0283] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0284] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
