Description

Image stabilization motor, camera module and electronic devices

[0001] This application claims priority to Chinese patent application filed on December 11, 2024, with application number 202411837847.5 and entitled "Shake Stabilization Motor, Camera Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of camera technology, and in particular to a stabilization motor, camera module and electronic device. Background Technology

[0003] With the widespread use of smartphones, tablets, and other electronic devices, users have increasingly higher demands for the image quality they produce. When shooting with electronic devices, camera shake is unavoidable and can severely impact image quality; therefore, image stabilization structures are necessary in camera modules. One common camera stabilization technology is image sensor-shift optical image stabilization, which uses a stabilization motor to move the image sensor, adjusting its position and orientation to correct shake. However, the reliability of the stabilization motors in this technology is relatively low, and the risk of motor failure is high. Summary of the Invention

[0004] This application provides a stabilization motor, a camera module, and an electronic device, wherein the stabilization motor has high reliability.

[0005] In a first aspect, embodiments of this application provide an image stabilization motor, which includes a suspension wire, a stator, and a mover. The stator includes a fixed platform and a clearance notch. The clearance notch is located on the side of the fixed platform facing the suspension wire along a direction perpendicular to the thickness direction of the image stabilization motor, and extends through the fixed platform along the thickness direction of the image stabilization motor. The clearance notch is used to avoid the suspension wire. The mover carries an image sensor. The suspension wire connects the mover and the fixed platform along a direction perpendicular to the thickness direction of the image stabilization motor. The center of gravity of the mover is located between the clearance notch and the geometric center of the mover, and the center of gravity and the geometric center of the mover are spaced apart.

[0006] During the operation of the image stabilization motor, all moving parts except the suspension wire constitute the mover, while the stationary parts except the suspension wire constitute the stator. The mover can drive the image sensor to translate or rotate, enabling the image sensor to suppress jitter in the three directions of X-axis translation, Y-axis translation, and Z-axis rotation, thus solving problems such as optical image instability and image rotation, and improving image quality.

[0007] Furthermore, during reliability testing of the image stabilization motor or during accidental drops or collisions of electronic devices, the center of gravity and geometric center of the mover do not coincide. The mover is prone to moving along a direction perpendicular to the thickness of the image stabilization motor, causing the suspension wire to collide with the stationary platform in that direction. The suspension wire becomes stuck and compressed by the stationary platform, easily leading to damage. In other words, the suspension wire has a high failure risk and low reliability. Therefore, this application's embodiment provides a clearance notch on the stationary platform to prevent collisions or compression between the suspension wire and the stationary platform, reducing the failure risk of the suspension wire and ensuring high reliability for the suspension wire, thereby enhancing the reliability of the image stabilization motor. Additionally, it also avoids the generation of microparticles from collisions between the suspension wire and the stationary platform, improving the performance of the image stabilization motor.

[0008] Furthermore, compared to traditional technologies that reduce the risk of suspension wire failure by increasing the width of the gap space, using the avoidance gap reduces the risk of suspension wire failure without increasing the width of the gap space. The gap width between the mover and the stationary stage can be designed to be small, making the size of the anti-shake motor smaller in the direction perpendicular to the thickness of the anti-shake motor, which helps to miniaturize the design of the anti-shake motor.

[0009] In one possible implementation, the stator further includes a coil circuit board, an integrated circuit, and a shield. The integrated circuit is electrically connected to one side of the coil circuit board. The shield includes a shield body and a lug plate, both located on the same side of the coil circuit board. The shield body and the coil circuit board form a receiving space for accommodating the integrated circuit. One end of the lug plate is fixedly connected to the shield body, and the lug plate is located outside the receiving space and adheres to the coil circuit board.

[0010] Typically, the coil circuit board is a flexible circuit board. When the anti-vibration motor shakes or the mover collides with the stator, the coil circuit board deforms under stress. If the deformation of the coil circuit board is too large, the solder joints between the integrated circuit (IC) and the coil circuit board will detach. To address this, a support plate is attached to the coil circuit board to increase its strength, prevent excessive deformation, and thus prevent the solder joints between the coil circuit board and the IC from detaching. Furthermore, since the IC is located within the shielding body, the shielding body can also transfer the stress near the IC from the coil circuit board to the support plate, preventing excessive deformation of the coil circuit board area near the IC and thus preventing the solder joints between the IC and the coil circuit board from detaching.

[0011] In one possible implementation, the stator further includes a coil circuit board, an integrated circuit, and a first reinforcing plate. The integrated circuit is electrically connected to one side of the coil circuit board. The first reinforcing plate is fixedly connected to the side of the coil circuit board away from the integrated circuit. At least a portion of the orthographic projection of the integrated circuit onto the coil circuit board is located inside the orthographic projection of the first reinforcing plate onto the coil circuit board.

[0012] Typically, the coil circuit board is a flexible circuit board. When the anti-vibration motor shakes or the mover collides with the stator, the coil circuit board deforms under stress. If the deformation of the coil circuit board is too large, the solder joints between the integrated circuit (IC) and the coil circuit board will detach. To address this, by placing a first reinforcing plate on the side of the coil circuit board away from the IC, the first reinforcing plate at least partially overlaps with the orthographic projection of the IC on the coil circuit board, the strength of the connection between the coil circuit board and the IC board can be improved, preventing excessive deformation of the coil circuit board and thus preventing the solder joints between the IC and the coil circuit board from detaching.

[0013] In one possible implementation, the mover further includes a first magnet bracket and a second magnet bracket. The second magnet bracket includes a bracket body and a connecting plate. The bracket body and the first magnet bracket are arranged at intervals along the thickness direction of the anti-shake motor. One end of the connecting plate is fixedly connected to the bracket body, and the other end of the connecting plate is fixedly connected to the first magnet bracket. The connecting plate is provided with a rib structure.

[0014] Both the first and second magnet brackets support magnets. The magnets work in conjunction with the stator coils to generate a driving force, causing the mover to move relative to the stator, thereby moving the image sensor and achieving optical image stabilization. Typically, the second magnet bracket is constructed of metal and plastic to reduce its weight, contributing to a lightweight design for the image stabilization motor. However, the connecting plate, also made of metal and plastic, has relatively low strength and is prone to deformation upon collision with the stator. Therefore, this embodiment incorporates a rib structure forming reinforcing ribs on the connecting plate, increasing its strength and reducing the risk of deformation.

[0015] In one possible implementation, the mover further includes a first magnet bracket and a second magnet bracket. The second magnet bracket includes a bracket body and a connecting plate. The bracket body and the first magnet bracket are spaced apart along the thickness direction of the stabilization motor. One end of the connecting plate is fixedly connected to the bracket body, and the other end of the connecting plate is fixedly connected to the first magnet bracket. Along the direction from the bracket body to the first magnet bracket, the width of the connecting plate gradually decreases in the width direction of the stabilization motor. Both end faces of the connecting plate in the width direction of the stabilization motor are inclined surfaces that are inclined to the thickness direction of the stabilization motor.

[0016] Typically, the second magnet bracket is constructed from a combination of metal and plastic to reduce its weight and achieve a lightweight design for the anti-shake motor. Consequently, the connecting plate, also made of metal and plastic, has relatively low strength and is prone to deformation upon collision with the stator. To address this, a draft design is implemented on the connecting plate, making its two end faces in the width direction of the anti-shake motor inclined surfaces. This reduces the collision area between the connecting plate and the stator in the width direction of the anti-shake motor, thereby minimizing the risk of deformation.

[0017] In one possible implementation, the mover further includes a first magnet bracket and a second magnet bracket. The first magnet bracket includes a first metal portion. The second magnet bracket includes a bracket body and a connecting plate. The bracket body and the first magnet bracket are spaced apart along the thickness direction of the anti-shake motor. One end of the connecting plate is fixedly connected to the bracket body, and the other end of the connecting plate includes a second metal portion, which is welded to the first metal portion. Along the length direction of the anti-shake motor, at least a portion of the orthographic projection of the portion of the second metal portion opposite to the first metal portion onto the first metal portion is located inside the first metal portion.

[0018] Typically, both the first and second magnet supports are constructed from metal and plastic materials to reduce the weight of the second magnet support and achieve a lightweight design for the anti-shake motor. Therefore, the connecting plate, also made of metal and plastic, has relatively low strength and is prone to deformation upon collision with the stator. In view of this, placing at least a portion of the second metal part's orthographic projection onto the first metal part within the first metal part increases the welding width between the first and second metal parts, improving the connecting plate's resistance to deformation.

[0019] In one possible implementation, the center lines of the first metal part and the second metal part coincide in the width direction of the stabilization motor.

[0020] In this implementation, the coincidence of the center lines of the first metal part and the second metal part means that the first metal part and the second metal part are centrally located, which allows the welding width of the first metal part and the second metal part to be maximized, further improving the deformation resistance of the connecting plate.

[0021] In one possible implementation, the mover further includes a first magnet bracket and a second magnet bracket. The second magnet bracket includes a bracket body and a connecting plate. The bracket body and the first magnet bracket are spaced apart along the thickness direction of the anti-shake motor. One end of the connecting plate is fixedly connected to the bracket body, and at least a portion of the end face of the connecting plate facing the stator along the length direction of the anti-shake motor is made of metal.

[0022] Typically, both the first and second magnet supports are constructed from metal and plastic materials to reduce the weight of the second magnet support and achieve a lightweight design for the anti-shake motor. During the movement of the anti-shake motor, the part of the second magnet support that collides with the stator is the connecting plate. The surface material of the connecting plate that collides with the stator is plastic. Due to the low strength of plastic, it is easily damaged after repeated collisions, causing the connecting plate to deform. Therefore, in this embodiment, by exposing the metal material in the connecting plate, the surface material of the connecting plate that collides with the stator is metal. Metal has high strength, giving the connecting plate high resistance to deformation.

[0023] In one possible implementation, the stator further includes a coil support and a housing. The coil support contacts and is fixedly connected to the stator. The housing is located along the thickness direction of the anti-shake motor on the side of the coil support away from the stator, and is welded to the coil support.

[0024] Typically, coil supports consist of a metal frame and plastic parts, resulting in low overall rigidity. This low rigidity leads to background noise issues. Therefore, this embodiment of the application welds the outer shell to the metal frame of the coil support, using the outer shell to support the coil support, increasing its rigidity, and thus optimizing the background noise.

[0025] In one possible implementation, the stator further includes a coil support, which comprises a first metal support and a first plastic part. The first metal support is an integral structure, and the first metal support is fixedly connected to the first plastic part.

[0026] Typically, coil supports consist of a metal frame and plastic parts. The overall stiffness of the coil support is relatively low, which leads to noise floor issues. Therefore, this embodiment employs a first metal support with an integrated structure as the metal frame. This first metal support has high stiffness, which increases the stiffness of the first plastic part and improves the stiffness of the coil support, thereby optimizing the line noise floor.

[0027] In one possible implementation, the stator further includes a cover plate and a coil support. The cover plate has a light-transmitting aperture for light to pass through. The coil support includes a first metal support and a first plastic part. The first metal support includes a metal body and a bent metal part. At least a portion of the metal body is embedded inside the first plastic part, and the bent metal part is fixedly connected to the cover plate.

[0028] Typically, coil supports consist of a metal frame and plastic parts. The overall stiffness of the coil support is relatively low, which can lead to background noise. To address this, bending the first metal support to form a bent metal section connected to the cover plate increases the stiffness of the first metal support, thereby increasing the stiffness of the first plastic part, and ultimately improving the stiffness of the coil support, thus optimizing the background noise.

[0029] In one possible implementation, the stator includes a housing cavity and a housing. The mover is located inside the housing cavity. The housing serves as part of the cavity wall and has a water-washing hole that communicates with the interior of the housing cavity.

[0030] Typically, during the assembly of an image stabilization motor, the presence of tiny particles inside the motor, known as a partilcle problem, can affect the movement of the actuator and / or the light-sensing performance of the image sensor, leading to degraded image quality. To address this, a water-washing hole is provided in the housing to clean the inside of the motor, removing particles, dust, and other foreign matter, thus improving or resolving the partilcle problem. The "particle" problem generally refers to the impact of tiny particles on motor performance.

[0031] In one possible implementation, the distance between the water washing hole and the bottom surface of the housing away from the suspension wire along the thickness direction of the stabilization motor is less than or equal to one-third of the thickness of the stabilization motor.

[0032] In this implementation, the distance between the water washing hole and the bottom surface of the housing is less than or equal to one-third of the motor thickness, which can reduce the difficulty of the cleaning medium such as liquid or gas used in the water washing process to discharge the anti-vibration motor and improve the water washing effect.

[0033] In one possible implementation, the stator further includes a coil support, a cover plate, a coil circuit board assembly, and a gel-like component. The cover plate is fixedly connected to the coil support. The coil circuit board assembly is fixedly connected to the coil support. At least one of the coil support, cover plate, and coil circuit board assembly has a gel-like component disposed on its surface.

[0034] In this implementation, the adhesive properties of the colloidal component adsorb tiny particles inside the anti-shake motor, thereby improving the partilcle problem.

[0035] In one possible implementation, the stator further includes a first flexible element, and the mover has first flexible elements on opposite sides along the length direction of the anti-shake motor.

[0036] During the operation of the image stabilization motor, the mover and stator collide along the length of the motor in a hard-on-hard collision, generating noise and potentially producing small particles that affect the reliability of the motor and the image quality of the image sensor. To address this, a first flexible component is placed between the mover and stator. As the mover moves along the length of the motor towards the stator, it collides with this flexible component, which acts as a buffer, reducing or eliminating the impact noise and preventing the generation of small particles.

[0037] In one possible implementation, the mover further includes a first magnet bracket and a second magnet bracket. At least a portion of the second magnet bracket is spaced apart from the first magnet bracket along the thickness direction of the stabilization motor, and the first flexible member faces at least one of the first and second magnet brackets along the length direction of the stabilization motor.

[0038] During the operation of the anti-shake motor, the specific parts where the mover and stator collide along the length of the motor are usually the first magnet bracket and / or the second magnet bracket. Therefore, by placing the first flexible member on opposite sides of the first magnet bracket and / or the second magnet bracket, the first magnet bracket and / or the second magnet bracket collide with the first flexible member, reducing or eliminating impact noise and preventing the generation of small particles.

[0039] In one possible implementation, the stator further includes a second flexible element, and the mover has second flexible elements on opposite sides along the width direction of the anti-shake motor.

[0040] During the operation of the image stabilization motor, the mover and stator collide along the width of the motor, and this collision is a hard-on-hard collision. This produces noise and can easily generate small particles, affecting the reliability of the image stabilization motor and the imaging quality of the image sensor. To address this, a second flexible component is placed between the mover and stator. When the mover moves along the width of the motor towards the stator and collides with the second flexible component, it acts as a buffer, reducing or eliminating the impact noise and preventing the generation of small particles.

[0041] In one possible implementation, the stator further includes a coil support, and the second flexible member is fixedly connected to the coil support. The mover further includes a first magnet support and a second magnet support, and the second flexible member faces at least one of the first magnet support and the second magnet support along the width direction of the anti-shake motor.

[0042] During the operation of the anti-shake motor, the specific parts where the mover and stator collide in the width direction of the anti-shake motor are usually the first magnet bracket and / or the second magnet bracket. Therefore, by setting the second flexible member on the opposite sides of the first magnet bracket and / or the second magnet bracket, the first magnet bracket and / or the second magnet bracket collide with the second flexible member, reducing or eliminating impact noise, and also avoiding the generation of small particles.

[0043] In one possible implementation, the mover includes a first magnet bracket and a second magnet bracket, the first magnet bracket being connected to the second magnet bracket. The stator includes a housing, a coil bracket, and a coil circuit board assembly, the housing and the coil circuit board assembly being fixedly connected to the coil bracket. The image stabilization motor further includes at least one of the following damping elements: a first damping element, a second damping element, and a third damping element. Specifically, along the thickness direction of the image stabilization motor, the first damping element is located between the bracket bodies of the first and second magnet brackets, one end of the first damping element contacting the first magnet bracket, and the other end contacting the coil circuit board assembly or the coil bracket. The second damping element is located along the thickness direction of the image stabilization motor between the housing and the first magnet bracket, with both ends contacting the housing and the first magnet bracket, respectively. The third damping element is located along the thickness direction of the image stabilization motor between the second magnet bracket and the coil bracket, with both ends contacting the coil bracket and the second magnet bracket, respectively.

[0044] In this implementation, by setting at least one of the first damping element, the second damping element, and the third damping element, the damping characteristics of the damping material are utilized to help improve the control performance of the anti-shake motor.

[0045] In one possible implementation, the mover further includes a first magnet element and a first magnet support. The first magnet support includes a first magnetic plate and a second magnetic plate, with the first magnetic plate located between the first magnet element and the second magnetic plate. The first magnet element is a Heilbeck magnet array.

[0046] In this implementation, the Helbeck magnet array combined with the dual-conducting magnetic sheet design achieves low restoring force. This means that when the stabilization motor stops receiving power, the interaction force between the magnets is small, reducing rebound or vibration and improving control accuracy. Low restoring force helps the stabilization motor reach the target position and stabilize more quickly, which is especially important for stabilization motors that require fast response.

[0047] In one possible implementation, the stator further includes a third magnet, which is located on the side of the second magnetic sheet away from the first magnetic sheet along the thickness direction of the anti-shake motor and is spaced apart from the second magnetic sheet. The third magnet is magnetically connected to the second magnetic sheet.

[0048] In this implementation, the third magnet is magnetically connected to the second magnetic sheet, meaning there is a magnetic attraction between them. Simultaneously, since the position of the third magnet remains unchanged, the magnetic attraction will hold the first magnet support in place, preventing it from accidentally moving towards the image sensor.

[0049] Secondly, embodiments of this application provide a camera module, which includes a lens, an image sensor, and a stabilization motor as described in any of the first aspects. The image sensor is located on the light-emitting side of the lens and is fixedly connected to the mover of the stabilization motor.

[0050] Thirdly, embodiments of this application provide an electronic device, which includes a housing and a camera module as described in the second aspect, the camera module being mounted on the housing. Attached Figure Description

[0087] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0088] This application provides an electronic device 100, including but not limited to mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, Bluetooth speakers, vehicle-mounted devices, and other devices with a camera module 120.

[0089] In this embodiment of the application, a mobile phone is used as an example of the above-mentioned electronic device 100 to specifically describe the structure of the electronic device 100 and the camera module 120.

[0090] Figure 1 is an exploded view of an electronic device provided in an embodiment of this application.

[0091] Referring to Figure 1, the electronic device 100 includes a housing 110, a display screen 130, and a camera module 120. The camera module 120 is mounted on the housing 110, which includes a middle frame 111 and a back cover 112. The back cover 112 and the display screen 130 are located on opposite sides of the middle frame 111 and are connected to the middle frame 111. The middle frame 111, the back cover 112, and the display screen 130 form a cavity for accommodating devices such as the battery 140 and the camera module 120.

[0092] The number of camera modules 120 can be one or more to meet different shooting needs. For example, the electronic device 100 can have two camera modules 120 installed on the front and three camera modules 120 installed on the back. This application embodiment does not limit the number of camera modules 120 installed. When multiple camera modules 120 are installed, they can be the same or different; for example, the number of lenses included in the multiple camera modules 120 may differ, or the optical parameters of the lenses may differ, or the lens placement may differ, etc.

[0093] The camera module 120 can be a standard camera module, a telephoto camera module, a wide-angle camera module, an ultra-telephoto camera module, an ultra-wide-angle camera module, etc.

[0094] It should be understood that the electronic device 100 shown in Figure 1 is not limited to the above-mentioned devices, but may also include other devices, such as a flash, a fingerprint recognition module, a handset, buttons, sensors, etc.

[0095] Figure 2 is a schematic diagram of the camera module in Figure 1.

[0096] Referring to Figure 2, the camera module 120 includes a lens 121, an image sensor 122, and a stabilization motor 123. The image sensor 122 is located on the light-emitting side of the lens 121 and is fixedly connected to the stabilization motor 123. When the electronic device 100 performs a shooting operation, the stabilization motor 123 drives the image sensor 122 to move, enabling the image sensor 122 to suppress shake in three directions: X-axis translation, Y-axis translation, and Z-axis rotation (in the XY plane). This solves problems such as optical image instability and image rotation, achieving optical image stabilization and improving shooting quality.

[0097] In related technologies, image stabilization motors include a stator, a mover, and a suspension wire. The mover is fixedly connected to the image sensor, and the suspension wire connects the stator and the mover. During reliability testing of the image stabilization motor or during accidental drops or collisions of electronic devices, as the mover moves relative to the stator, the suspension wire is easily jammed and compressed by the stator, leading to damage. Therefore, the low reliability of image stabilization motors results in a high risk of failure.

[0098] One reason why the suspension wire gets stuck on the stator is that the center of gravity and geometric center of the mover do not coincide. In other words, the center of gravity of the mover is offset, and the mover is prone to move along a direction perpendicular to the thickness direction Z of the image stabilization motor. This causes the suspension wire to collide with the stator in that direction, resulting in the wire getting stuck and being squeezed. The wire is easily damaged, meaning the failure risk of the suspension wire is high and its reliability is low. Additionally, the collision between the suspension wire and the stator can easily generate tiny particles, leading to a particulate problem, which affects the performance of the image stabilization motor and the imaging quality of the image sensor. The "particle" problem typically refers to the impact of tiny particles on motor performance.

[0099] For example, the Chinese meaning of "partilcle" can be particulate matter, so the partilcle problem can be called the particulate matter problem.

[0100] In one implementation, increasing the distance between the mover and stator in the direction of movement of the mover can prevent the suspension wire from colliding with the stator, thus preventing the suspension wire from failing. However, this method results in a larger distance between the mover and stator, leading to a larger size of the anti-shake motor and making it difficult to miniaturize. Therefore, how to improve the reliability of the anti-shake motor without increasing its size has become an urgent problem to be solved.

[0101] In view of this, this application provides a shake stabilization motor 123. By providing a clearance notch 325 on the stator 90 at a location where it is easily squeezed by the suspension wire 322, the suspension wire 322 is prevented from being stuck and squeezed by the stator 90, thereby improving the reliability of the suspension wire 322 and reducing the risk of failure of the suspension wire 322, thus achieving the purpose of improving the reliability of the shake stabilization motor 123. In addition, the clearance notch 325 improves the reliability of the suspension wire 322 without increasing the size of the shake stabilization motor 123, which helps to achieve miniaturization of the shake stabilization motor 123 while maintaining high reliability and improving the partilcle problem.

[0102] The anti-shake motor 123 provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0103] In this embodiment, the anti-shake motor 123 includes a cover 10, a main circuit board assembly 30, a filter carrier 20, a filter (not shown in the figure), a coil bracket 61, a first magnet bracket 41, a second magnet bracket 42, a first magnet component 43, a second magnet component 44, a coil circuit board assembly 50, and a case 62.

[0104] Figure 3 is a three-dimensional structural diagram of the anti-shake motor provided in the embodiment of this application.

[0105] As shown in Figure 3, along the thickness direction Z of the anti-shake motor 123, the cover plate 10 is located on one side of the coil bracket 61 and is fixedly connected to the coil bracket 61, and the outer shell 62 is located on the other side of the coil bracket 61 and is fixedly connected to the coil bracket 61. The cover plate 10, the coil bracket 61 and the outer shell 62 can together form an arrangement space, which is used to accommodate the main circuit board assembly 30, the coil circuit board assembly 50, the first magnet bracket 41, the second magnet bracket 42, the first magnet 43, the second magnet 44, the filter carrier 20, the filter, the image sensor 122 and other devices.

[0106] Figure 4 is a three-dimensional structural diagram of the coil support in Figure 3, and Figure 5 is an exploded view of the coil support shown in Figure 4.

[0107] To effectively balance the strength and weight of the coil support 61, as shown in Figures 4 and 5, the coil support 61 may include a first metal support 611 and a first plastic part 612, with the first metal support 611 serving as the metal skeleton of the coil support 61. At least a portion of the first metal support 611 is embedded inside the first plastic part 612; for example, a portion of the first metal support 611 is disposed inside the first plastic part 612.

[0108] The first metal bracket 611 and the first plastic part 612 are joined together by injection molding. In some feasible processes, the first metal bracket 611 is placed in a mold, and then the first plastic part 612 is formed on the first metal bracket 611 by injection molding.

[0109] Figure 6 is a three-dimensional structural diagram of the cover plate in Figure 3.

[0110] Referring to Figure 6, the cover plate 10 has a light-transmitting hole 11. The light-transmitting hole 11 is located on the photosensitive side of the image sensor 122 and is positioned opposite to the photosensitive surface of the image sensor 122. The light-transmitting hole 11 allows light incident on the photosensitive surface of the image sensor 122 to pass through. The cover plate 10 can be fixedly connected to the coil support 61 by means of welding, snap-fitting, threaded connection, etc. For example, the cover plate 10 is welded to the coil support 61.

[0111] In some embodiments, to effectively balance the strength and weight of the cover plate 10, as shown in FIG6, the cover plate 10 may include a second metal bracket 12 and a second plastic part 13. The second metal bracket 12 and the second plastic part 13 are fixedly connected, and the second metal bracket 12 may be a mesh structure. The second metal bracket 12 and the second plastic part 13 can be integrally formed by injection molding. The second metal bracket 12 is welded to the first metal bracket 611 of the coil bracket 61.

[0112] Figure 7 is a top view of the main circuit board assembly in Figure 3.

[0113] As shown in Figure 7, the main circuit board assembly 30 includes an external circuit board 31, a main circuit board 32, and a carrier circuit board 33.

[0114] Figure 8 is a cross-sectional view of the main circuit board and the carrier circuit board in Figure 7.

[0115] As shown in Figure 8, the carrier circuit board 33 and the main circuit board 32 are stacked on top of each other. The carrier circuit board 33 and the main circuit board 32 are mechanically and electrically connected by a moving platform 323. The carrier circuit board 33 is used to carry the image sensor 122 and is electrically connected to the image sensor 122. The image sensor 122 is electrically connected to the main circuit board 32 through the carrier circuit board 33. The image sensor 122 and the main circuit board 32 are located on opposite sides of the carrier circuit board 33.

[0116] Referring to Figures 7 and 8, the first end of the external circuit board 31 is electrically connected to the end face of the fixed platform 321 of the main circuit board 32. The external circuit board 31 is used for electrical connection with the processor on the motherboard within the electronic device 100. The external circuit board 31 can be a flexible circuit board. In some embodiments, the external circuit board 31 is located outside the arrangement space. In other embodiments, a portion of the external circuit board 31 may be located inside the arrangement space, and another portion may be located outside the arrangement space.

[0117] Figure 9 is a three-dimensional structural diagram of the main circuit board in Figure 8, and Figure 10 is a top view of the main circuit board shown in Figure 9.

[0118] As shown in Figures 9 and 10, the main circuit board 32 includes a fixed platform 321, a movable platform 323, and a suspension wire 322. The fixed platform 321 is located around the movable platform 323, and there is a gap space 324 between the fixed platform 321 and the movable platform 323. The suspension wire 322 is located within the gap space 324. The movable platform 323 is mechanically and electrically connected to the fixed platform 321 through the suspension wire 322. During the operation of the anti-shake motor 123, the fixed platform 321 remains stationary, while the movable platform 323 moves relative to the fixed platform 321. The suspension wire 322 deforms under the action of the movable platform 323.

[0119] The specific structure of the suspension wire 322 is not limited here. For example, as shown in FIG10, the suspension wire 322 includes two flexible connection structures 3221. Each flexible connection structure 3221 includes a connecting part 3223 and a plurality of strip-shaped parts 3222. The plurality of strip-shaped parts 3222 are arranged at intervals along a direction perpendicular to the thickness direction Z of the anti-shake motor 123. Two adjacent strip-shaped parts 3222 are connected through a connecting part 3223. One end of each strip-shaped part 3222 is connected to the moving stage 323, and the other end of each strip-shaped part 3222 is connected to the fixed stage 321.

[0120] As shown in Figure 10, the two flexible connection structures 3221 are a first flexible connection structure 3221a and a second flexible connection structure 3221b, respectively. One end of the strip-shaped portion 3222 of the first flexible connection structure 3221a and one end of the strip-shaped portion 3222 of the second flexible connection structure 3221b are connected to opposite sides of the moving platform 323, respectively. The other end of the strip-shaped portion 3222 of the first flexible connection structure 3221a and the other end of the strip-shaped portion 3222 of the second flexible connection structure 3221b are connected to opposite sides of the fixed platform 321, respectively.

[0121] The specific number of strips 3222 is not limited here. For example, as shown in Figure 10, each flexible connection structure 3221 may include four strips 3222.

[0122] As shown in Figure 10, the fixed platform 321 can be a closed ring structure. In other examples, the fixed platform 321 can also be an open ring-like structure.

[0123] Figure 11 is a cross-sectional view of the anti-shake motor shown in Figure 3 from the first perspective.

[0124] As shown in Figure 11, along the thickness direction Z of the anti-shake motor 123, the fixed stage 321 is located between the coil support 61 and the cover plate 10. One side of the moving stage 323 is mechanically and electrically connected to the supporting circuit board 33. The other side of the moving stage 323 is fixedly connected to the second magnet support 42.

[0125] As shown in Figure 11, one side of the fixed platform 321 is connected to the cover plate 10, for example, the fixed platform 321 is bonded to the cover plate 10. The other side of the fixed platform 321 is connected to the coil support 61, for example, the fixed platform 321 is bonded to the coil support 61.

[0126] As shown in Figure 11, the anti-shake motor 123 also includes a connector 71, which is located between the moving platform 323 and the second magnetic support 42. The orthographic projection of the connector 71 on the moving platform 323 is located inside the moving platform 323. The connector 71 is fixedly connected to both the moving platform 323 and the second magnetic support 42, and the moving platform 323 is fixedly connected to the second magnetic support 42 through the connector 71. Of course, in some embodiments, the moving platform 323 can also be directly connected to the second magnetic support 42, for example, the moving platform 323 can be bonded to the second magnetic support 42.

[0127] In this embodiment, when the anti-shake motor 123 is working, the parts of the anti-shake motor 123 that move at least partially, excluding the suspension wire 322, constitute the mover 80, and the parts of the anti-shake motor 123 that remain stationary, excluding the suspension wire 322, constitute the stator 90. Therefore, in this embodiment, the mover 80 may include, but is not limited to, the first magnet support 41, the second magnet support 42, the first magnet 43, the second magnet 44, the moving platform 323, the connector 71, the filter carrier 20, the carrier circuit board 33, and other devices mentioned above. The stator 90 may include, but is not limited to, the coil support 61, the coil circuit board assembly 50, the housing 62, the cover plate 10, the stationary platform 321, and other devices mentioned above.

[0128] For example, as shown in FIG11, the mover 80 may include a first magnet support 41, a second magnet support 42, a first magnet 43, a second magnet 44, a moving platform 323, a connector 71, a filter carrier 20, and a carrier circuit board 33, and the stator 90 may include a coil support 61, a housing 62, a cover plate 10, and a stationary platform 321.

[0129] For example, referring to Figure 11, the stator 90 may include a receiving cavity 91, with the mover 80 and suspension wire 322 both located inside the receiving cavity 91. The mover 80 is used to support the image sensor 122, and the suspension wire 322 is connected between the mover 80 and the fixed platform 321 of the stator 90. The mover 80 is movably connected to the stator 90 via the suspension wire 322. When the image stabilization motor 123 is working, the mover 80 drives the image sensor 122 to move relative to the stator 90. The mover 80 can drive the image sensor 122 to translate or rotate, enabling the image sensor 122 to suppress jitter in the three directions of X-axis translation, Y-axis translation, and Z-axis rotation, solving problems such as optical image instability and image rotation, and improving image quality.

[0130] In this embodiment, the center of gravity and geometric center of the mover 80 do not coincide, or in other words, the center of gravity and geometric center of the mover 80 are spaced apart, or the center of gravity deviates from the geometric center. The center of gravity refers to the average position of the mass distribution of an object. The geometric center refers to the center point of all boundaries of an object, that is, the center of the object's shape. Therefore, during reliability testing of the anti-shake motor 123 or during accidental drop or collision of the electronic device 100, the mover 80 is prone to move along a direction perpendicular to the thickness direction Z of the anti-shake motor 123, or in other words, it moves along the direction covering the center of gravity and geometric center of the mover 80 towards the side where the center of gravity is far from the geometric center. This causes the suspension wire 322 to collide with the fixed platform 321 in this direction. The suspension wire 322 is stuck and squeezed by the fixed platform 321, and the suspension wire 322 is easily damaged. That is, the failure risk of the suspension wire 322 is high, and the reliability of the suspension wire 322 is low.

[0131] In view of this, as shown in FIG10, in this embodiment of the application, an avoidance notch 325 is provided on the fixed platform 321. The avoidance notch 325 is located on the side of the fixed platform 321 facing the suspension wire 322 in the direction perpendicular to the thickness direction Z of the anti-shake motor 123. The avoidance notch 325 penetrates the fixed platform 321 in the thickness direction Z of the anti-shake motor 123 and communicates with the gap space 324. In the direction perpendicular to the thickness direction Z of the anti-shake motor 123, the center of gravity of the mover 80 is located between the avoidance notch 325 and the geometric center of the mover 80. When the mover 80 moves towards the clearance notch 325 along the Z direction perpendicular to the thickness direction of the anti-shake motor 123, it avoids the suspension wire 322 through the clearance notch 325. The suspension wire 322 will not contact the stationary platform 321, thus preventing collisions or compression between them. This reduces the risk of failure of the suspension wire 322, ensuring its high reliability, and consequently, the high reliability of the anti-shake motor 123. Furthermore, the absence of collision between the suspension wire 322 and the stationary platform 321 prevents the generation of small particles.

[0132] In addition, compared with the traditional method of increasing the width of the gap space 324 to prevent the suspension wire 322 from colliding with the fixed platform 321, the embodiment of this application sets an avoidance notch 325 to avoid the suspension wire 322 in the local area where the fixed platform 321 collides with the suspension wire 322. This reduces the failure risk of the suspension wire 322 without increasing the width of the gap space 324 in the direction perpendicular to the thickness Z of the anti-shake motor 123. The width of the gap space 324 can still be designed to be small, so the size of the main circuit board 32 in the direction perpendicular to the thickness Z of the anti-shake motor 123 is smaller, which helps to miniaturize the design of the anti-shake motor 123.

[0133] The specific structure of the clearance notch 325 is not limited here. For example, as shown in Figure 10, the clearance notch 325 can be a strip-shaped notch. Furthermore, the specific dimensions of the clearance notch 325 are not limited here. For example, the depth of the clearance notch 325 in the width direction of the image stabilization motor 123 can be greater than 0.1 mm, and the length of the clearance notch 325 in the length direction X of the image stabilization motor 123 can be greater than 2 mm.

[0134] Figure 12 is a cross-sectional view of the anti-shake motor shown in Figure 3 from a second perspective.

[0135] To improve the stability of the image sensor 122's movement, in some embodiments, as shown in FIG12, the carrier circuit board 33 can also be fixedly connected to the second magnet bracket 42. For example, the second magnet bracket 42 has a connector 4211, which is connected to the carrier circuit board 33 through a gap 324 between the fixed platform 321 and the moving platform 323. To further improve the connection strength between the carrier circuit board 33 and the second magnet bracket 42, in some embodiments, the connector 4211 may include a connecting main part and a connecting rod part, the connecting main part being bonded to the carrier circuit board 33, and the connecting rod part being inserted into a through hole on the carrier circuit board 33.

[0136] As shown in Figure 12, the filter carrier 20 is fixedly connected to the side of the carrier circuit board 33 away from the main circuit board 32, and the filter carrier 20 can be bonded to the carrier circuit board 33. The filter carrier 20 is used to carry the filter (not shown in the figure). At this time, the filter is positioned opposite to the image sensor 122, and the filter is located on the photosensitive side of the image sensor 122. The filter can be bonded to the filter carrier 20. The filter carrier 20 can have a frame structure, surrounding the filter without obstructing the image sensor 122.

[0137] After light from outside the camera module 120 enters the optical components within the image stabilization motor 123, it passes sequentially through a light filter and the image sensor 122. Finally, the image sensor 122 converts the light signal into an image target signal. The light filter can block certain wavelengths of light, allowing only certain wavelengths to pass through, and also provides some protection for the image sensor 122. For example, the filter can be an infrared filter, which can block infrared light while allowing other wavelengths to pass through.

[0138] As shown in Figure 12, the second magnet 44 is fixedly connected to the second magnet bracket 42, and the second magnet 44 may include one or more second magnets. The first magnet 43 is used to interact with the coil in the coil circuit board assembly 50 to generate a driving force to move the image sensor 122.

[0139] Figure 13 is a three-dimensional structural diagram of the first magnet support, the second magnet support, and the first magnet component in Figure 15.

[0140] As shown in Figure 13, the first magnet 43 is fixedly connected to the first magnet bracket 41, and the first magnet 43 may include one or more first magnets. The second magnet 44 is used to interact with the coil in the coil circuit board assembly 50 to generate a driving force to move the image sensor 122.

[0141] Figure 14 is a three-dimensional structural diagram of the second magnet support in Figure 13.

[0142] The first magnet bracket 41 and the second magnet bracket 42 are fixedly connected. For example, to achieve this fixed connection, as shown in Figure 14, the second magnet bracket 42 includes a bracket body 421 and two connecting plates 422. The two connecting plates 422 are located at opposite ends of the bracket body 421 along the length X direction of the anti-shake motor 123. Along the thickness Z direction of the anti-shake motor 123, one end of the connecting plate 422 is fixedly connected to the bracket body 421, and the other end of the connecting plate 422 is fixedly connected to the first magnet bracket 41.

[0143] Figure 15 is a cross-sectional view of the anti-shake motor shown in Figure 3 from a third perspective.

[0144] As shown in Figure 15, the support body 421 and the first magnet support 41 are arranged at intervals along the thickness direction Z of the anti-shake motor 123. The support body 421 is located between the main circuit board 32 and the coil support 61. The support body 421 is fixedly connected to the moving platform 323 of the main circuit board 32.

[0145] As shown in Figure 15, the first magnet bracket 41 is located between the outer shell 62 and the coil bracket 61. To connect the first magnet bracket 41 and the second magnet bracket 42, in some embodiments, the coil bracket 61 has a through space 613, and the connecting plate 422 is fixedly connected to the first magnet bracket 41 through the through space 613. The through space 613 is a through hole that passes through the coil bracket 61 along the thickness direction Z of the anti-shake motor 123, and the connecting plate 422 passes through the through hole and is fixedly connected to the first magnet bracket 41. The through spaces 613 and the connecting plates 422 correspond one-to-one. For example, as shown in Figure 15, there are two connecting plates 422, and correspondingly, there are two through spaces 613.

[0146] At least a portion of the second magnet bracket 42 is spaced apart from the first magnet bracket 41 along the thickness direction Z of the anti-shake motor 123, as shown in Figure 15. For example, a portion of the second magnet bracket 42 is spaced apart from the first magnet bracket 41 along the thickness direction Z of the anti-shake motor 123. As shown in Figure 15, the first magnet bracket 41 and the second magnet bracket 42 can form a ring structure. In this case, the coil circuit board assembly 50 is located inside the ring structure formed by the first magnet bracket 41 and the second magnet bracket 42, or in other words, the coil circuit board assembly 50 is located between the first magnet bracket 41 and the second magnet bracket 42.

[0147] For example, in order to ensure the strength of the first magnet bracket 41 and the second magnet bracket 42 and to control the weight of the first magnet bracket 41 and the second magnet bracket 42, both the first magnet bracket 41 and the second magnet bracket 42 are made of two materials: metal and plastic. The metal material forms the skeleton of the first magnet bracket 41 and the second magnet bracket 42, and the first magnet bracket 41 and the second magnet bracket 42 are formed by injection molding.

[0148] Figure 16 is a three-dimensional structural diagram of the coil circuit board assembly in Figure 3 from a first perspective, and Figure 17 is a three-dimensional structural diagram of the coil circuit board assembly in Figure 3 from a second perspective.

[0149] Referring to Figure 15, and in conjunction with Figures 16 and 17, the coil circuit board assembly 50 may include a coil circuit board 51, a first coil 56, a second coil 57, a third coil 58, an integrated circuit (IC) 52, and a shielding cover 53. The coil circuit board 51 is fixedly connected to the coil support 61 and electrically connected to the mounting plate 321 of the main circuit board 32. The first coil 56, the second coil 57, the shielding cover 53, and the integrated circuit 52 are all located on the side of the coil circuit board 51 away from the main circuit board 32. The first coil 56, the second coil 57, and the integrated circuit 52 are each electrically connected to the coil circuit board 51. The shielding cover 53 is fixedly connected to the coil circuit board 51 and forms a receiving space for the integrated circuit 52. The third coil 58 is located on the side of the coil circuit board 51 closer to the main circuit board 32 and is electrically connected to the coil circuit board 51.

[0150] Referring to Figure 15, to allow the first magnet 43 to interact with the first coil 56 to generate a driving force, and to allow the first magnet 43 to interact with the second coil 57 to generate a driving force, the first magnet 43, the first coil 56, and the second coil 57 are all located between the coil circuit board 51 and the first magnet bracket 41. To allow the third coil 58 to interact with the second magnet 44 to generate a driving force, the coil bracket 61 has a mounting through hole, the third coil 58 is located inside the mounting through hole, and the second magnet 44 is located between the third coil 58 and the bracket body 421 of the second magnet bracket 42.

[0151] Please refer to Figure 16. There are two third coils 58. The third coils 58 interact with the second magnet to generate a driving force that moves the image sensor 122 along the X-axis.

[0152] Referring to Figure 17, there is one first coil 56 and two second coils 57. Along the length X of the stabilization motor 123, the first coil 56 is located between the two second coils 57. Both the first coil 56 and the second coil 57 interact with the first magnet 43. The interaction between the first coil 56 and the first magnet 43 generates a driving force that moves the image sensor 122 along the Y-axis, while the interaction between the two second coils 57 and the first magnet 43 generates a driving force that rotates the image sensor 122 about the Z-axis.

[0153] In some examples, the coil circuit board 51 is a flexible circuit board, and the integrated circuit (IC) 52 is electrically connected to the coil circuit board 51 by soldering, that is, there are solder joints between the integrated circuit 52 and the coil circuit board 51. However, when the anti-shake motor 123 shakes or the mover 80 collides with the stator 90, the coil circuit board 51 is deformed due to stress. If the deformation of the coil circuit board 51 is too large, the solder joints between the integrated circuit 52 and the coil circuit board 51 will fall off, and the anti-shake motor 123 will not work properly.

[0154] Please refer to Figure 17, and also refer to Figures 18 and 19. Figure 18 is a cross-sectional view of the coil circuit board assembly shown in Figure 16, and Figure 19 is a three-dimensional structural view of the shield in Figure 16.

[0155] To further improve the strength of the solder joints between the integrated circuit 52 and the coil circuit board 51, in some possible implementations, the shield 53 may include a shield body 531 and a support plate 532. The shield body 531 and the support plate 532 are located on the same side of the coil circuit board 51, forming a receiving space for the integrated circuit 52. One end of the support plate 532 is fixedly connected to the shield body 531, and the support plate 532 is located outside the receiving space and adheres to the coil circuit board 51.

[0156] By attaching the lug plate 532 to the coil circuit board 51, the strength of the coil circuit board 51 can be increased, preventing excessive deformation of the coil circuit board 51 and preventing the solder joints between the coil circuit board 51 and the integrated circuit 52 from falling off. In addition, since the integrated circuit 52 is located inside the shielding body 531, the shielding body 531 can also transfer the stress near the integrated circuit 52 from the coil circuit board 51 to the lug plate 532, preventing excessive deformation of the coil circuit board 51 portion near the integrated circuit 52 and preventing the solder joints between the integrated circuit 52 and the coil circuit board 51 from falling off.

[0157] In some embodiments, the shielding body 531 may include a first plate, two first support plates, and a second support plate. The integrated circuit 52 is located between the first plate and the coil circuit board 51 along the thickness direction Z of the anti-shake motor 123. The two first support plates are located on opposite sides of the first plate. One end of the first support plate is fixedly connected to the first plate, and the other end of the first support plate is fixedly connected to the coil circuit board 51. The second support plate is located on the same side of the first plate and between the two first support plates. One end of the second support plate is fixedly connected to the first plate, and the other end of the second support plate is fixedly connected to the ear plate 532.

[0158] In some embodiments, the shielding body 531 can be bonded to the coil circuit board 51, as shown in FIG17, where a first adhesive 72 is provided between the first support plate and the coil circuit board 51. The first adhesive 72, in addition to connecting the coil circuit board 51 and the coil circuit board 51, can also improve the strength of the coil circuit board 51, helping to reduce the degree of deformation of the coil circuit board 51.

[0159] Referring to Figures 17 and 18, to ensure a tight fit between the lug plate 532 and the coil circuit board 51, the anti-shake motor 123 also includes a second adhesive component 73. A portion of the second adhesive component 73 covers the surface of the lug plate 532, and another portion covers the surface of the coil circuit board 51. The coil circuit board 51 is fixedly connected to the lug plate 532 via the second adhesive component 73. To further enhance the connection strength of the second adhesive component 73, its orthographic projection on the coil circuit board 51 is U-shaped, and the second adhesive component 73 covers the edge of the lug plate 532.

[0160] For example, integrated circuit 52 may include a substrate layer, a device layer, an interconnect layer, a package layer, and solder joints.

[0161] To further protect the solder joints between the integrated circuit 52 and the coil circuit board 51 support, in some embodiments, as shown in FIG18, the stator 90 further includes a first reinforcing plate 54. The first reinforcing plate 54 is fixedly connected to the side of the coil circuit board 51 away from the integrated circuit 52, and at least a portion of the orthographic projection of the integrated circuit 52 on the coil circuit board 51 is located inside the orthographic projection of the first reinforcing plate 54 on the coil circuit board 51. Therefore, since at least a portion of the first reinforcing plate 54 is located directly below the integrated circuit 52, it can improve the strength of the connection between the coil circuit board 51 and the integrated circuit 52, prevent excessive deformation of the coil circuit board 51, and prevent the solder joints between the integrated circuit 52 and the coil circuit board 51 from detaching.

[0162] In order to achieve a fixed connection between the first reinforcing plate 54 and the coil circuit board 51, in some embodiments, the anti-shake motor 123 may also include a third adhesive component, which is located between the first reinforcing plate 54 and the coil circuit board 51 and is respectively bonded to the first reinforcing plate 54 and the coil circuit board 51.

[0163] In addition to both the first reinforcing plate 54 and the shielding cover 53 with the lug plate 532 existing simultaneously, in some scenarios, the first reinforcing plate 54 can also be set separately to protect the solder joints. Alternatively, in some scenarios, the shielding cover 53 with the lug plate 532 can also be set separately to protect the solder joints.

[0164] In some possible implementations, as shown in Figure 18, the stator 90 further includes a second reinforcing plate 55, which is located on the same side of the coil circuit board 51 as the first reinforcing plate 54. The second reinforcing plate 55 is attached to the coil circuit board 51, with one end of the second reinforcing plate 55 close to the lug plate 532. This further enhances the strength of the coil circuit board 51, thereby controlling its deformation within a reasonable range.

[0165] In some embodiments, as shown in FIG18, a portion of the second adhesive 73 covers the surface of one end of the second reinforcing plate 55, and the second reinforcing plate 55 is fixedly connected to the coil circuit board 51 by the second adhesive 73. Alternatively, one end of the second reinforcing plate 55 can be welded to the first metal bracket 611 of the coil support 61 to fix the second reinforcing plate 55 onto the coil circuit board 51.

[0166] When the anti-shake motor 123 is working, the mover 80 collides with the stator 90. The first magnet bracket 41 and the second magnet bracket 42 of the mover 80 collide with the outer shell 62 of the stator 90 in the length direction X of the anti-shake motor 123, and the second magnet bracket 42 of the mover 80 collides with the coil bracket 61 of the stator 90 in the width direction Y of the anti-shake motor 123. As described above, the second magnet bracket 42 is made of metal and plastic to reduce its weight and achieve a lightweight design for the anti-shake motor 123. Therefore, the connecting plate 422 of the second magnet bracket 42 is also made of metal and plastic. The connecting plate 422 has low strength and is prone to deformation after repeated collisions with the outer shell 62, leading to cracking at the weld between the connecting plate 422 and the first magnet bracket 41 and changes in the position of the first magnet component 43.

[0167] Figure 20 is a schematic diagram of another structure of the second magnet bracket and the first magnet bracket provided in the embodiment of this application, and Figure 21 is an enlarged schematic diagram of point P in Figure 20.

[0168] In some possible implementations, at least a portion of the end face of the connecting plate 422 facing the stator 90 along the length X of the anti-shake motor 123 is made of metal. For example, as shown in Figure 21, the portion of the end face of the connecting plate 422 facing the housing 62 along the length X of the anti-shake motor 123 (k in Figure 21) is made of metal. Thus, during the collision between the connecting plate 422 and the stator 90, the surface of the connecting plate 422 colliding with the stator 90 is made of metal. Compared to the plastic surface of the connecting plate 422 colliding with the stator 90 in Figure 15, metal has higher strength than plastic and is less prone to deformation. This reduces the risk of deformation of the connecting plate 422, giving it high resistance to deformation.

[0169] In some possible implementations, as shown in Figure 21, the connecting plate 422 of the second magnet bracket 42 is provided with a rib structure 423 forming a reinforcing rib, which makes the connecting plate 422 have high strength, reduces the risk of deformation of the connecting plate 422, and prevents the connecting plate 422 from deforming.

[0170] As shown in Figure 21, a rib structure 423 is provided on the connecting plate 422, and multiple rib structures 423 may also be provided on the connecting plate 422. Furthermore, as shown in Figure 21, the extending direction of the rib structure 423 is parallel to the thickness direction Z of the anti-shake motor 123; however, the extending direction of the rib structure 423 may also be perpendicular to the thickness direction Z of the anti-shake motor 123 or intersect with the thickness direction Z of the anti-shake motor 123.

[0171] It is understandable that the rib structure 423 is set on the metal material of the connecting plate 422, and the metal material on the connecting plate 422 can be stamped to form the rib structure 423.

[0172] In some possible implementations, as shown in Figure 21, the first magnet bracket 41 includes a first metal part 411, and the end of the connecting plate 422 away from the bracket body 421 includes a second metal part 4221. The second metal part 4221 is welded to the first metal part 411, thereby fixing the first magnet bracket 41 and the second magnet bracket 4221 together. Along the length direction X of the anti-shake motor 123, at least a portion of the orthographic projection of the part of the second metal part 4221 opposite to the first metal part 411 onto the first metal part 411 is located inside the first metal part 411, thereby increasing the welding width between the first metal part 411 and the second metal part 4221. The first metal part 411 supports the second metal part 4221, thereby improving the deformation resistance of the connecting plate 422.

[0173] In some embodiments, along the length direction X of the image stabilization motor 123, the first metal portion 411 is located on the side of the second metal portion 4221 away from the housing 62 and overlaps with the second metal portion 4221. In other embodiments, the first metal portion 411 may also be located on the side of the second metal portion 4221 closer to the housing 62 and overlap with the second metal portion 4221. In still other embodiments, the first metal portion 411 and the second metal portion 4221 may not overlap in the length direction X of the image stabilization motor 123.

[0174] It is understandable that the wider the welding width of the first metal part 411 and the second metal part 4221 in the width direction Y of the anti-shake motor 123, the better the connection between the first metal part 411 and the second metal part 4221, the better the support of the first metal part 411 for the second metal part 4221, the better the deformation resistance of the second metal part 4221, and thus the better the deformation resistance of the connecting plate 422.

[0175] In some embodiments, as shown in FIG21, the first metal portion 411 and the second metal portion 4221 have the same width in the width direction Y of the image stabilization motor 123. In other embodiments, the widths of the first metal portion 411 and the second metal portion 4221 in the width direction Y of the image stabilization motor 123 may be different.

[0176] In some possible implementations, as shown in Figure 21, the center lines of the first metal part 411 and the second metal part 4221 coincide in the width direction Y of the anti-shake motor 123. The coincidence of the center lines of the first metal part 411 and the second metal part 4221 means that the first metal part 411 and the second metal part 4221 are centrally located, so that the welding width of the first metal part 411 and the second metal part 4221 can be maximized, thereby further improving the deformation resistance of the second metal part 4221, and further improving the deformation resistance of the connecting plate 422.

[0177] Figure 22 is a left-side view of another embodiment of the present application showing the second magnet bracket cooperating with the first magnet bracket.

[0178] In some possible implementations, as shown in Figure 22, along the direction from the support body 421 to the first magnet support 41, the width of the connecting plate 422 in the width direction Y of the anti-shake motor 123 gradually decreases. Both end faces of the connecting plate 422 in the width direction Y of the anti-shake motor 123 are inclined surfaces that are inclined to the thickness direction Z of the anti-shake motor 123 (as shown by u1 in Figure 22). Therefore, the orthographic projection of the connecting plate 422 onto the reference plane is similar to an isosceles trapezoid, and the reference plane is the plane containing the width direction Y and the thickness direction Z of the anti-shake motor 123.

[0179] During the manufacturing process of the second magnet bracket 42, a draft design is performed on the connecting plate 422, making the two end faces of the connecting plate 422 in the width direction Y of the anti-shake motor 123 inclined surfaces. This reduces the collision area between the connecting plate 422 and the coil bracket 61 in the width direction Y of the anti-shake motor 123, thereby reducing the risk of deformation of the connecting plate 422. Furthermore, the surfaces of the connecting plate 422 and the coil bracket 61 that collide in the width direction Y of the anti-shake motor 123 are made of plastic. By reducing the collision area between the plastic and the coil bracket 61, the amount of microparticles generated by the collision can also be reduced.

[0180] It should be noted that, in addition to setting the end face of the connecting plate 422 that collides with the coil bracket 61 as an inclined surface, in some scenarios, the size of the surface of the coil bracket 61 that collides with the connecting plate 422 in the thickness direction Z of the anti-shake motor 123 can be reduced, or set as an inclined surface, which can also reduce the collision area between the coil bracket 61 and the connecting plate 422.

[0181] In summary, the deformation of the connecting plate 422 can be reduced by at least one of the following methods: exposing the metal material inside the connecting plate 422, setting the rib structure 423, ensuring that the projections of the first metal part 411 and the second metal part 4221 at least partially overlap, and setting the two end faces of the connecting plate 422 as inclined surfaces. The more methods used, the better the effect on the connecting plate 422.

[0182] Figure 23 is a cross-sectional schematic diagram showing the first flexible element set on opposite sides of the first magnet support and the second magnet support.

[0183] In some possible implementations, as shown in Figure 23, the first magnet bracket 41 includes a first magnetic sheet 412 and a second magnetic sheet 413. The first magnetic sheet 412 is located between the first magnet element 43 and the second magnetic sheet 413. The first magnet element 43 is a Helbeck magnet array. The Helbeck magnet array combined with the dual magnetic sheet design can achieve a lower restoring force. This means that when the anti-shake motor 123 stops receiving power, the interaction force between the magnets is small, reducing rebound or vibration and improving control accuracy. The low restoring force helps the anti-shake motor 123 reach the target position and stabilize more quickly, which is especially important for the anti-shake motor 123 that requires a fast response.

[0184] In some possible implementations, as shown in Figure 23, the stator 90 further includes a third magnet 45. Along the thickness direction Z of the image stabilization motor 123, the third magnet 45 is located on the side of the second magnetic sheet 413 away from the first magnetic sheet 412, and the third magnet 45 and the second magnetic sheet 413 are spaced apart. The third magnet 45 and the second magnetic sheet 413 are magnetically connected, meaning there is a magnetic attraction between them. Simultaneously, since the position of the third magnet 45 remains unchanged, the magnetic attraction will hold the first magnet support 41, preventing the first magnet support 41 from accidentally moving towards the image sensor 122. Furthermore, the Helbeck magnet array combined with the dual magnetic sheets forms a strong magnetic attraction structure, which is insensitive to the distance between the third magnet 45 and the second magnetic sheet 413 in the thickness direction Z of the image stabilization motor 123, facilitating assembly and debugging. Therefore, there is no need to separately provide a magnetic sheet to cooperate with the third magnet 45.

[0185] The third magnet component 45 may include one or more third magnets, which is not limited here.

[0186] For example, as shown in FIG23, the third magnet 45 can be fixed to the inner wall of the housing 62, for example, the third magnet 45 is bonded to the inner wall of the housing 62.

[0187] When the image stabilization motor 123 is working, the collision between the mover 80 and the stator 90 will generate abnormal noise, affecting the user experience and potentially being captured by the audio recording equipment during video recording, thus affecting audio quality. Furthermore, the collision between the mover 80 and the stator 90 in the length direction X of the image stabilization motor 123 is a hard-on-hard collision, which may generate tiny particles, further affecting the reliability of the image stabilization motor 123 and the imaging quality of the image sensor 122.

[0188] During the operation of the image stabilization motor 123, the mover 80 and stator 90 may collide along the length X of the motor 123. Therefore, in some possible implementations, as shown in Figure 23, the stator 90 further includes a first flexible member 64. The first flexible member 64 is provided on both opposite sides of the mover 80 along the length X of the motor 123. By providing the first flexible member 64 between the mover 80 and the stator 90, when the mover 80 moves towards the stator 90 along the length X of the motor 123 and collides with the first flexible member 64, the first flexible member 64 acts as a buffer, reducing or eliminating impact noise and preventing the appearance of small particles, thus improving image quality.

[0189] The specific material of the first flexible member 64 is not limited here. For example, the first flexible member 64 can be silicone.

[0190] As shown in Figure 23, the first flexible member 64 is fixedly connected to the inner wall of the outer casing 62. Of course, the first flexible member 64 can also be fixedly installed on other parts of the stator 90 besides the outer casing 62.

[0191] In some embodiments, as shown in FIG23, the first flexible member 64 may be bonded to the housing 62. In other embodiments, the first flexible member 64 may also be formed on the housing 62 by injection molding, so that the first flexible member 64 and the housing 62 form an integral structure.

[0192] In addition to being integrated onto the stator 90, the first flexible component 64 can also be integrated onto the mover 80 in some scenarios. Integrating the first flexible component 64 onto the stator 90 can reduce the weight of the mover 80 and make it easier to move the mover 80.

[0193] During the operation of the anti-shake motor 123, the parts where the mover 80 and stator 90 collide along the length X of the anti-shake motor 123 can be the first magnet bracket 41 and / or the second magnet bracket 42. Therefore, in some possible implementations, along the length X of the anti-shake motor 123, the first flexible member 64 faces at least one of the first magnet bracket 41 and the second magnet bracket 42, for example, as shown in FIG. 23, the first flexible member 64 faces the first magnet bracket 41 and the second magnet bracket 42. By placing the first flexible member 64 on opposite sides of the first magnet bracket 41 and / or the second magnet bracket 42, the collision between the first magnet bracket 41 and / or the second magnet bracket 42 and the stator 90 is a soft-on-hard collision, thereby improving or resolving impact noise and avoiding the generation of small particles.

[0194] Figure 24 is a three-dimensional structural diagram of a second flexible element set on a coil support, and Figure 25 is a cross-sectional diagram of the second flexible element in conjunction with the coil support, the first magnet support, and the second magnet support.

[0195] During the operation of the anti-shake motor 123, the mover 80 and stator 90 will collide in the width direction Y of the anti-shake motor 123. Therefore, in some possible implementations, as shown in Figures 24 and 25, the stator 90 also includes a second flexible member 65. The second flexible member 65 is fixedly connected to the coil support 61, and the mover 80 has second flexible members 65 on both opposite sides along the width direction Y of the anti-shake motor 123. By providing the second flexible member 65 between the mover 80 and the stator 90, when the mover 80 moves towards the stator 90 along the width direction Y of the anti-shake motor 123, it will collide with the second flexible member 65. The second flexible member 65 acts as a buffer, reducing or eliminating impact noise and preventing the generation of small particles.

[0196] The specific material of the second flexible member 65 is not limited here. For example, the second flexible member 65 can be silicone.

[0197] In some implementations, as shown in Figure 25, the second flexible member 65 is formed on the coil support 61 by injection molding, so that the second flexible member 65 and the coil support 61 form an integral structure. In other embodiments, the second flexible member 65 can be bonded to the coil support 61.

[0198] It should be noted that, in addition to being integrated onto the stator 90, the second flexible component 65 can also be integrated onto the mover 80 in some scenarios. Integrating the second flexible component 65 onto the stator 90 can reduce the weight of the mover 80 and make it easier to move the mover 80.

[0199] During the operation of the anti-shake motor 123, the specific parts where the mover 80 and stator 90 collide in the width direction Y of the anti-shake motor 123 are typically the first magnet bracket 41 and / or the second magnet bracket 42. Therefore, in some possible implementations, the second flexible member 65 faces at least one of the first magnet bracket 41 and the second magnet bracket 42 along the width direction Y of the anti-shake motor 123, for example, as shown in Figure 25, the second flexible member 65 faces the second magnet bracket 42. By placing the second flexible member 65 on opposite sides of the first magnet bracket 41 and / or the second magnet bracket 42, the collision between the first magnet bracket 41 and / or the second magnet bracket 42 and the stator 90 is a soft-on-hard collision, thereby improving or resolving impact noise and avoiding the generation of small particles.

[0200] For example, as shown in FIG25, the coil support 61 collides with the connecting plate 422 of the second magnet support 42. Therefore, the second flexible member 65 faces the connecting plate 422 of the second magnet support 42. The distance between the second flexible member 65 and the connecting plate 422 in the width direction Y of the anti-shake motor 123 is less than the distance between the coil support 61 and the connecting plate 422. The distance between the second flexible member 65 and the connecting plate 422 in the width direction Y of the anti-shake motor 123 is less than the distance between the coil support 61 and the first magnet support 41.

[0201] As described above, the coil support 61 consists of a first metal support 611 and a first plastic part 612. While achieving a lightweight design, the coil support 61 also results in low overall rigidity. Consequently, during the operation of the anti-shake motor 123, the low rigidity of the coil support 61 will lead to background noise (i.e., low-frequency noise or vibration). The following are some possible reasons for this background noise:

[0202] 1. Low-stiffness coil support 61 is more prone to resonance. When the natural frequency of the support is close to the external excitation frequency (such as the motor drive frequency), resonance occurs, resulting in a large vibration amplitude. This resonance is transmitted throughout the system, generating significant background noise. 2. Low-stiffness coil support 61 is prone to deformation or displacement under stress. In the anti-shake motor 123, the coil needs to move precisely to counteract hand tremors. Insufficient support stiffness leads to imprecise coil movement, introducing additional vibration and noise. 3. Low-stiffness coil support 61 affects the system's control accuracy. The anti-shake motor 123 typically relies on high-precision position sensors and feedback control systems for rapid and accurate adjustments. Insufficient support stiffness results in unstable position feedback signals, making it difficult for the control system to precisely control the coil's position, thus increasing background noise. 4. Low-stiffness coil support 61 may experience more mechanical losses during movement, such as friction and deformation. These losses not only reduce system efficiency but also generate additional vibration and noise. 5. In some cases, the low-stiffness coil support 61 may cause changes in the relative position between the coil and the magnet, thereby affecting the distribution of the electromagnetic field. This change may cause electromagnetic interference, further increasing the background noise.

[0203] To reduce the background noise caused by the low-stiffness coil support 61, the following measures can be taken:

[0204] In some possible implementations, the housing 62 is located along the thickness direction Z of the anti-shake motor 123 on the side of the coil support 61 away from the stationary platform 321, and the housing 62 is welded to the coil support 61. For example, the housing 62 can be welded to the first metal bracket 611 of the coil support 61. By supporting the coil support 61 with the housing 62, the rigidity of the coil support 61 can be increased, effectively reducing the background noise problem caused by the low rigidity of the coil support 61, thus achieving the purpose of optimizing the operating noise.

[0205] Figure 26 is a first-view schematic diagram of the connection between the coil support and the outer shell in Figure 3, and Figure 27 is a second-view schematic diagram of the connection between the coil support and the outer shell in Figure 3.

[0206] The specific welding positions between the first metal bracket 611 and the outer casing 62 are not limited here. For example, as shown in Figure 26, there are three welding positions (H1, H2, and H3 in Figure 26) between one side of the outer casing 62 and the first metal bracket 611, which are spaced apart along the length of the anti-shake motor 123. There are also three welding positions (H4, H5, and H6 in Figure 27) between the other side of the outer casing 62 and the first metal bracket 611, which are spaced apart along the length of the anti-shake motor 123.

[0207] Figure 28 is a three-dimensional structural diagram of the first metal support in Figure 5.

[0208] In some possible implementations, as shown in Figure 28, the first metal bracket 611 is an integral structure. The first metal bracket 611 with an integral structure serves as a metal skeleton. The first metal bracket 611 has high rigidity, which can increase the rigidity of the first plastic part 612, thereby improving the rigidity of the coil bracket 61 and thus achieving the purpose of optimizing the operating noise.

[0209] Figure 29 is a first-view schematic diagram of the coil support and cover plate connected in Figure 3, and Figure 30 is a second-view schematic diagram of the coil support and cover plate connected in Figure 3.

[0210] In some possible implementations, as shown in Figure 29, the coil support 61 includes a first metal support 611 and a first plastic part 612. As shown in Figure 28, the first metal support 611 includes a metal main body 6111 and a metal bent portion 6112. At least a portion of the metal main body 6111 is embedded inside the first plastic part 612, and the metal bent portion 6112 is fixedly connected to the cover plate 10. By bending the first metal support 611 to form the metal bent portion 6112 connected to the second metal support 12 of the cover plate 10, the rigidity of the first metal support 611 can be increased, thereby increasing the rigidity of the first plastic part 612. Consequently, the coil support 61 possesses high rigidity, which can effectively reduce the background noise problem caused by a low-rigidity coil support 61.

[0211] As can be seen from Figures 29 and 30, metal bending portions 6112 are provided on both opposite sides of the metal main body 6111, so that the opposite sides of the first metal bracket 611 are welded to the opposite sides of the second metal bracket 23 respectively.

[0212] Typically, during the assembly of the image stabilization motor 123, the presence of tiny particles inside the motor can cause a partilcle problem, affecting the operation of the mover 80 and / or the photosensitivity of the image sensor 122, resulting in degraded image quality. The "particle" problem usually refers to the impact of tiny particles on motor performance. The partilcle problem can be improved through the following measures:

[0213] Figure 31 is a three-dimensional structural diagram of the outer shell in Figure 3.

[0214] In some possible implementations, as shown in Figure 31, the outer casing 62 serves as part of the cavity wall of the receiving chamber 91 and has a water washing hole 63 that communicates with the interior of the receiving chamber 91. Thus, the water washing hole 63 can act as a through-hole for liquid or gas to enter the interior of the anti-shake motor 123, allowing for cleaning of the interior using deionized water, compressed air, or a suitable cleaning agent. This directly removes particles adhering to the mover 80, stator 90, and suspension wire 322. Therefore, through a well-designed water washing hole 63, the particle problem inside the anti-shake motor 123 can be effectively solved, improving the overall performance and reliability of the anti-shake motor 123.

[0215] Understandably, after cleaning, the cleaning medium is drained through the water rinse hole 63 to ensure the interior is dry. Additionally, after draining the cleaning medium, the water rinse hole 63 needs to be sealed, for example, by using sealant.

[0216] The specific shape of the water washing hole 63 is not limited here. For example, the water washing hole 63 can be a circular hole.

[0217] In some embodiments, as shown in FIG31, the water washing hole 63 is located on one side of the housing 62 along the length direction X of the anti-shake motor 123. In other embodiments, the water washing hole 63 may also be located on one side of the housing 62 along the width direction Y of the anti-shake motor 123. In still other embodiments, the water washing hole 63 may also be located on the portion of the housing 62 opposite to the first magnet bracket 41 along the thickness direction Z of the anti-shake motor 123.

[0218] In some embodiments, along the thickness direction Z of the anti-shake motor 123, the distance between the water washing hole 63 and the bottom surface of the housing 62 away from the suspension wire 322 is less than or equal to one-third of the thickness of the anti-shake motor 123. This can reduce the difficulty of the cleaning medium used in the water washing process being discharged from the inside of the anti-shake motor 123 and can improve the water washing effect.

[0219] In some possible implementations, the image stabilization motor 123 also includes a gel component (not shown in the figure). This gel component can be positioned at the location where the mover 80 and stator 90 collide; however, its placement is not limited to this location. Because the gel component is a low-viscosity adhesive, it has poor flowability and can remain in one position for an extended period. The gel component can adsorb small particles, preventing them from flowing within the image stabilization motor 123.

[0220] The specific type of colloidal component is not limited here. For example, the colloidal component can be a dust-repairing adhesive.

[0221] In some embodiments, at least one of the coil support 61, cover plate 10 and coil circuit board assembly 50 has a surface provided with a gel-like material. For example, the surfaces of the coil support 61, cover plate 10 and coil circuit board assembly 50 are all provided with a gel-like material.

[0222] There are no specific limitations on where the gel member can be placed on the coil support 61. For example, the gel member can be placed at a location where the coil support 61 collides with the support body 421 of the second magnet support 42 in the thickness direction Z perpendicular to the stabilization motor 123. Exemplarily, the gel member can be placed on the surface of the coil support 61 that collides with the second magnet support 42 along the length direction X and width direction Y of the stabilization motor 123.

[0223] The specific location of the colloid component on the cover plate 10 is not limited here. For example, the colloid component can be placed on the surface of the cover plate 10 opposite to the second magnet bracket 42 in a direction perpendicular to the thickness direction Z of the anti-shake motor 123.

[0224] There are no restrictions on the location of the adhesive component on the coil circuit board assembly 50. For example, the adhesive component can be placed on the surface of the shield 53, the surface of the second reinforcing plate 55, etc.

[0225] To improve the control performance of the image stabilization motor 123, in some possible implementations, the image stabilization motor 123 may further include at least one of the following damping elements: a first damping element 66, a second damping element 67, and a third damping element 68. For example, the image stabilization motor 123 includes a first damping element 66, a second damping element 67, and a third damping element 68.
