Description

Technical Field

[0001] This application relates to the field of camera technology, and in particular to a stabilization motor, camera module and electronic device. Background Technology

[0002] 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

[0003] This application provides a stabilization motor, a camera module, and an electronic device, wherein the stabilization motor has high reliability.

[0004] 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.

[0005] 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.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] 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, and at least a portion of the orthographic projection of the integrated circuit onto the coil circuit board lies within the orthographic projection of the first reinforcing plate onto the coil circuit board.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] In this implementation, the adhesive properties of the colloidal component adsorb tiny particles inside the anti-shake motor, thereby improving the partilcle problem.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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

[0103] 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.

[0104] 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.

[0105] 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.

[0106] Figure 1 This is an exploded view of an electronic device provided in an embodiment of this application.

[0107] See Figure 1 As shown, 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, the camera module 120, and the battery 140.

[0108] 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.

[0109] 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.

[0110] It should be understood that Figure 1 The electronic device 100 shown 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, a battery 140, etc.

[0111] Figure 2 for Figure 1A schematic diagram of the camera module in the image.

[0112] See Figure 2 As shown, 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.

[0113] 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.

[0114] Through careful analysis, the inventors of this application discovered that one reason the suspension wire is stuck by 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 tends 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 suspension wire being stuck and compressed by the stator. This makes the suspension wire prone to damage, meaning it has a high failure risk and low reliability. Furthermore, the collision between the suspension wire and the stator easily generates 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.

[0115] To address this issue, one implementation increases the distance between the mover and stator in the direction of the mover's movement, preventing the suspension wire from colliding with the stator and thus avoiding wire failure. However, this method results in a larger distance between the mover and stator, leading to a larger size of the anti-shake motor and hindering its miniaturization. Therefore, improving the reliability of the anti-shake motor without increasing its size has become a pressing problem.

[0116] In view of this, this application provides a shake-stabilizing motor 123. By providing a clearance notch 325 on the stator at a location where the suspension wire 322 is easily squeezed, the suspension wire 322 is prevented from being stuck and squeezed by the stator, 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-stabilizing motor 123. In addition, improving the reliability of the suspension wire 322 by using the clearance notch 325 does not increase the size of the shake-stabilizing motor 123, which helps to achieve miniaturization of the shake-stabilizing motor 123 while maintaining high reliability, and also improves the partilcle problem.

[0117] The anti-shake motor 123 provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0118] Figure 3 This is a three-dimensional structural diagram of the anti-shake motor provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shown is a cross-sectional view of the image stabilization motor from a first-person perspective. Figure 5 for Figure 3 The diagram shows a cross-sectional view of the image stabilization motor from a second perspective. Figure 6 for Figure 3 A three-dimensional structural diagram of the coil support in the image. Figure 7 for Figure 6 The diagram shown is an exploded view of the coil support. Figure 8 for Figure 3 A three-dimensional structural diagram of the cover plate.

[0119] In this embodiment, the image stabilization 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 housing 62. Wherein, as... Figure 3 As shown, 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 a part of 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.

[0120] To effectively balance the strength and weight of the coil support 61, combined with Figure 6 and Figure 7It is understood that 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.

[0121] The first metal bracket 611 and the first plastic part 612 are combined by injection molding. Specifically, 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.

[0122] See Figure 8 As shown, 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 bracket 61 by means of welding, snap-fitting, threaded connection, etc., for example... Figure 3 As shown, the cover plate 10 is welded to the coil support 61. In some embodiments, to effectively balance the strength and weight of the cover plate 10, such as... Figure 8 As shown, 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 being 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.

[0123] Figure 9 for Figure 3 A top view of the main circuit board assembly. Figure 10 for Figure 9 A cross-sectional view of the main circuit board and the carrier circuit board mating together. Figure 11 for Figure 10 A three-dimensional structural diagram of the main circuit board. Figure 12 for Figure 11 The diagram shows a top view of the main circuit board.

[0124] like Figure 9 As shown, the main circuit board assembly 30 includes an external circuit board 31, a main circuit board 32, and a carrier circuit board 33. Wherein, as... Figure 11 and Figure 12As shown, 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, and the movable platform 323 is mechanically and electrically connected to the fixed platform 321 through the suspension wire 322. Figure 5 As shown, along the thickness direction Z of the anti-shake motor 123, the stationary platform 321 is located between the coil support 61 and the cover plate 10. Figure 10 As shown, one side of the moving stage 323 is mechanically and electrically connected to the supporting circuit board 33. (As indicated...) Figure 5 As shown, the other side of the movable stage 323 is fixedly connected to the second magnet bracket 42. During the operation of the anti-shake motor 123, the position of the fixed stage 321 remains stationary, while the movable stage 323 moves relative to the fixed stage 321, and the suspension wire 322 deforms under the action of the movable stage 323.

[0125] The specific structure of the suspension wire 322 is not limited here. For example, as shown... Figure 12 As shown, 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 the direction perpendicular to the thickness direction Z of the anti-shake motor 123. Two adjacent strip-shaped parts 3222 are connected by 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.

[0126] like Figure 12 As shown, 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 respectively connected to opposite sides of the moving platform 323, and 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 respectively connected to opposite sides of the fixed platform 321.

[0127] The specific number of strip-shaped portions 3222 is not specifically limited here, for example... Figure 12 As shown, each flexible connection structure 3221 may include four strip-shaped portions 3222.

[0128] like Figure 12 As shown, the fixed platform 321 can be a closed ring structure. Of course, the fixed platform 321 can also be an open ring-like structure.

[0129] like Figure 5As shown, 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.

[0130] like Figure 5 As shown, 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.

[0131] 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.

[0132] like Figure 10 As shown, 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.

[0133] Figure 13 for Figure 3 The diagram shows a cross-sectional view of the anti-shake motor from a third-view perspective.

[0134] To improve the stability of the movement of the image sensor 122, in some embodiments, such as Figure 13 As shown, 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. 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.

[0135] like Figure 13As shown, 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.

[0136] 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.

[0137] Figure 14 for Figure 4 A three-dimensional structural diagram showing the combination of the first magnet support, the second magnet support, and the first magnet component.

[0138] like Figure 14 As shown, the first magnet component 43 is fixedly connected to the first magnet bracket 41, and the first magnet component 43 may include one or more first magnets. Figure 13 As shown, 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. Both the first magnet 43 and the second magnet 44 are used to interact with the coil in the coil circuit board assembly 50 to generate a driving force that moves the image sensor 122.

[0139] like Figure 14 As shown, the first magnet bracket 41 and the second magnet bracket 42 are fixedly connected. At least a portion of the second magnet bracket 42 and the first magnet bracket 41 are arranged at intervals along the thickness direction Z of the anti-shake motor 123, for example... Figure 4 As shown, portions of the second magnet bracket 42 and the first magnet bracket 41 are arranged at intervals along the thickness direction Z of the anti-shake motor 123. Figure 4 As shown, the first magnet bracket 41 and the second magnet bracket 42 can form a ring structure. At this time, 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.

[0140] 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.

[0141] Figure 15 for Figure 14 A three-dimensional structural diagram of the second magnet support in the image.

[0142] To achieve a fixed connection between the first magnet bracket 41 and the second magnet bracket 42, such as Figure 15 As shown, the second magnet support 42 includes a support body 421 and two connecting plates 422. Wherein, as... Figure 4 As shown, the support body 421 and the first magnet bracket 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 bracket 61, and the support body 421 is fixedly connected to the moving platform 323 of the main circuit board 32. Two connecting plates 422 are located at opposite ends of the support body 421 along the length direction X of the anti-shake motor 123. Along the thickness direction Z of the anti-shake motor 123, one end of the connecting plate 422 is fixedly connected to the support body 421, and the other end of the connecting plate 422 is fixedly connected to the first magnet bracket 41.

[0143] like Figure 4 As shown, the first magnet support 41 is located between the housing 62 and the coil support 61. In some embodiments, to connect the first magnet support 41 and the second magnet support 42, such as... Figure 6 As shown, the coil support 61 has a through space 613, and the connecting plate 422 is fixedly connected to the first magnet support 41 through the through space 613. For example Figure 6 As shown, 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. The connecting plate 422 passes through the through hole and is fixedly connected to the first magnet bracket 41. The through space 613 and the connecting plate 422 correspond one-to-one. For example, Figure 4 As shown, there are two connecting plates 422, and correspondingly, there are two through spaces 613.

[0144] Figure 16 for Figure 3 A first-person perspective three-dimensional structural diagram of the coil circuit board assembly. Figure 17 for Figure 3 A three-dimensional structural diagram of the coil circuit board assembly from a second-view perspective. Figure 18 for Figure 16The diagram shows a cross-sectional view of the coil circuit board assembly. Figure 19 for Figure 16 A three-dimensional structural diagram of the shielding cover.

[0145] like Figure 16 As shown, 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 52 (IC), and a shielding cover 53. Wherein, as... Figure 4 As shown, the coil circuit board 51 is fixedly connected to the coil bracket 61 and electrically connected to the fixed platform 321 of the main circuit board 32. Figure 16 As shown, the first coil 56, the second coil 57, the shield 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 electrically connected to the coil circuit board 51, and the shield 53 is fixedly connected to the coil circuit board 51 and forms a receiving space for accommodating the integrated circuit 52. Figure 17 As shown, the third coil 58 is located on the side of the coil circuit board 51 close to the main circuit board 32 and is electrically connected to the coil circuit board 51.

[0146] Among them, such as Figure 16 As shown, 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 first coil 56 interacts with the first magnet 43 to generate a driving force that moves the image sensor 122 along the Y-axis, and the two second coils 57 interact with the first magnet 43 to generate a driving force that rotates the image sensor 122 about the Z-axis.

[0147] Among them, such as Figure 17 As shown, there are two third coils 58, which interact with the second magnet to generate a driving force that moves the image sensor 122 along the X-axis.

[0148] like Figure 4 As shown, to allow the first magnet 43 to interact with the first coil 56 and the second coil 57, 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, 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.

[0149] In this embodiment, when the anti-shake motor 123 is working, all moving parts in the anti-shake motor 123, except for the suspension wire 322, are defined as the mover, and all stationary parts in the anti-shake motor 123, except for the suspension wire 322, are defined as the stator. Therefore, in this embodiment, the mover 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, etc., as described above, and the stator 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, etc., as described above.

[0150] Among them, see Figure 4 As shown, the stator includes a housing cavity, and the mover and suspension wire 322 are both located inside the housing cavity. The mover carries the image sensor 122, and the suspension wire 322 connects the mover and the fixed platform 321 of the stator. The mover is movably connected to the stator via the suspension wire 322. When the image stabilization motor 123 is working, the mover drives the image sensor 122 to move relative to the stator. The mover 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.

[0151] In this embodiment, the center of gravity and geometric center of the mover do not coincide, or in other words, the center of gravity and geometric center 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 is prone to move along a direction perpendicular to the thickness direction Z of the anti-shake motor 123, or in other words, move along a direction covering the center of gravity and geometric center of the mover 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.

[0152] In view of this, such as Figure 12As shown, in this embodiment, a clearance notch 325 is provided on the fixed platform 321. The clearance notch 325 is located on the side of the fixed platform 321 facing the suspension wire 322 along the thickness direction Z perpendicular to the anti-shake motor 123. The clearance notch 325 penetrates the fixed platform 321 along the thickness direction Z of the anti-shake motor 123 and communicates with the gap space 324. Along the thickness direction Z perpendicular to the anti-shake motor 123, the center of gravity of the mover is located between the clearance notch 325 and the geometric center of the mover. When the mover moves towards the clearance notch 325 along the thickness direction Z perpendicular to the anti-shake motor 123, it avoids the suspension wire 322 by passing through the clearance notch 325. The suspension wire 322 will not contact the fixed platform 321, avoiding collision or compression between the suspension wire 322 and the fixed platform 321, reducing the failure risk of the suspension wire 322, making the suspension wire 322 highly reliable, and thus the anti-shake motor 123 highly reliable. In addition, the suspension wire 322 does not collide with the fixed platform 321, which can avoid the generation of small particles.

[0153] 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.

[0154] The specific structure of the avoidance gap 325 is not limited here. For example... Figure 12 As shown, 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.

[0155] Typically, the coil circuit board 51 is a flexible circuit board, and the integrated circuit 52 (IC) is electrically connected to the coil circuit board 51 by soldering, meaning 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 collides with the stator, the coil circuit board 51 deforms under 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 detach, thus preventing the anti-shake motor 123 from working properly.

[0156] To further improve the strength of the solder joints between integrated circuit 52 and coil circuit board 51, in some possible implementations, such as Figure 19 As shown, the shielding cover 53 may include a shielding body 531 and a lug plate 532. Wherein, as... Figure 18 As shown, the shielding body 531 and the ear plate 532 are located on the same side of the coil circuit board 51. The shielding body 531 and the coil circuit board 51 form a receiving space for accommodating the integrated circuit 52. One end of the ear plate 532 is fixedly connected to the shielding body 531. The ear plate 532 is located outside the receiving space and is attached to the coil circuit board 51.

[0157] like Figure 18 As shown, by attaching the lug plate 532 to the coil circuit board 51, the strength of the coil circuit board 51 can be improved, 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.

[0158] 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.

[0159] In some embodiments, the shielding body 531 can be adhered to the coil circuit board 51, specifically, as shown below. Figure 16 As shown, a first adhesive component 72 is provided between the first support plate and the coil circuit board 51. The first adhesive component 72, in addition to connecting the coil circuit board 51 and the coil circuit board 51, also serves to increase the strength of the coil circuit board 51, helping to reduce the degree of deformation of the coil circuit board 51.

[0160] In order to ensure that the lug plate 532 fits tightly against the coil circuit board 51, such as Figure 16 and Figure 18As shown, 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 improve the connection strength of the second adhesive component 73, such as... Figure 16 As shown, the orthographic projection of the second adhesive component 73 on the coil circuit board 51 is U-shaped, and the second adhesive component 73 covers the edge of the ear plate 532.

[0161] To further protect the solder joints between the integrated circuit 52 and the coil circuit board 51 support, in some embodiments, such as Figure 18 As shown, the stator also includes a first reinforcing plate 54, which is fixedly connected to the side of the coil circuit board 51 away from the integrated circuit 52. At least a portion of the orthographic projection of the integrated circuit 52 onto the coil circuit board 51 is located inside the orthographic projection of the first reinforcing plate 54 onto 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] It should be noted that, in addition to the simultaneous presence of the first reinforcing plate 54 and the shielding cover 53 with the lug plate 532, 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, such as Figure 16 As shown, the stator also 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, and one end of the second reinforcing plate 55 is close to the lug plate 532. In this way, the strength of the coil circuit board 51 can be further improved, so that the deformation of the coil circuit board 51 can be controlled within a reasonable range.

[0165] In some embodiments, such as Figure 17As shown, 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 via the second adhesive 73. Additionally, one end of the second reinforcing plate 55 can be welded to the first metal bracket 611 of the coil bracket 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 collides with the stator. Specifically, the first magnet bracket 41 and the second magnet bracket 42 of the mover collide with the outer shell 62 of the stator in the length direction X of the anti-shake motor 123, and the second magnet bracket 42 of the mover collides with the coil bracket 61 of the stator 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, which can lead 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 This is a schematic diagram illustrating another possible combination of a second magnet holder and a first magnet holder according to an embodiment of this application. Figure 21 for Figure 20 Enlarged schematic diagram of point P in the middle.

[0168] In some possible implementations, at least a portion of the end face of the connecting plate 422 facing the stator along the length X direction of the anti-shake motor 123 is made of metal, for example... Figure 21 As shown, the portion of the connecting plate 422 facing the outer casing 62 along the length X direction of the anti-shake motor 123 (e.g.) Figure 21 The material of (k) is metal. Thus, during the collision between the connecting plate 422 and the stator, the surface of the connecting plate 422 colliding with the stator is made of metal, compared to... Figure 4 The surface material of the connecting plate 422 that collides with the stator is plastic. Metal has higher strength than plastic and is not easily deformed, which can reduce the risk of deformation of the connecting plate 422 and give the connecting plate 422 high resistance to deformation.

[0169] In some possible implementations, such as Figure 21 As shown, 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] like Figure 21 As shown, a rib structure 423 is provided on the connecting plate 422; however, multiple rib structures 423 may also be provided on the connecting plate 422. Additionally, as... Figure 21 As shown, the extension direction of the rib structure 423 is parallel to the thickness direction Z of the anti-shake motor 123. However, the extension 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. At this time, the metal material on the connecting plate 422 can be stamped to form the rib structure 423.

[0172] In some possible implementations, such as Figure 21 As shown, 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 to achieve a fixed connection between the first magnet bracket 41 and the second magnet bracket 42. Along the length direction X of the anti-shake motor 123, at least a portion of the portion of the second metal part 4221 opposite to the first metal part 411 is located inside the first metal part 411, which increases 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 to improve 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, such as Figure 21As shown, the first metal part 411 and the second metal part 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 part 411 and the second metal part 4221 in the width direction Y of the image stabilization motor 123 may not be the same.

[0176] In some possible implementations, such as Figure 21 As shown, 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 This is a left-side view of another embodiment of the second magnet bracket cooperating with the first magnet bracket.

[0178] In some possible implementations, such as Figure 22 As shown, along the direction from the main 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 (e.g., ...). Figure 22 (As shown in u1). It can be seen that the orthographic projection of the connecting plate 422 on 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] When the image stabilization motor 123 is working, the collision between the moving part and the stator will generate abnormal noise, which will affect the user experience and may also be captured by the audio recording equipment during video recording, affecting audio quality. In addition, the collision between the moving part and the stator in the length direction X of the image stabilization motor 123 is a hard-on collision, which may generate tiny particles, thereby affecting the reliability of the image stabilization motor 123 and the imaging quality of the image sensor 122.

[0183] Figure 23 A cross-sectional schematic diagram showing the first flexible element installed on opposite sides of the first magnet support and the second magnet support.

[0184] During the operation of the anti-shake motor 123, the mover and stator will collide along the length direction X of the anti-shake motor 123. Therefore, in some possible implementations, see [reference needed]. Figure 23 As shown, the stator also includes a first flexible member 64, and the mover has first flexible members 64 on both opposite sides along the length direction X of the anti-shake motor 123. By setting the first flexible member 64 between the mover and the stator, when the mover moves towards the stator along the length direction X of the anti-shake motor 123 and collides with the first flexible member 64, the first flexible member 64 acts as a buffer, which reduces or eliminates impact noise, avoids the appearance of small particles, and improves image quality.

[0185] The specific material of the first flexible member 64 is not limited here. For example, the first flexible member 64 can be silicone.

[0186] like Figure 23 As shown, 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 besides the outer casing 62.

[0187] In some embodiments, such as Figure 23As shown, the first flexible member 64 can be bonded to the outer shell 62. In other embodiments, the first flexible member 64 can also be formed on the outer shell 62 by injection molding, so that the first flexible member 64 and the outer shell 62 form an integral structure.

[0188] It should be noted that, in addition to being integrated onto the stator, the first flexible component 64 can also be integrated onto the mover in some scenarios. Integrating the first flexible component 64 onto the stator can reduce the weight of the mover and simplify its movement.

[0189] During the operation of the image stabilization motor 123, the specific parts where the moving part and the stator collide along the length direction X of the image stabilization motor 123 are typically the first magnet bracket 41 and / or the second magnet bracket 42. Therefore, in some possible implementations, along the length direction X of the image stabilization 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... Figure 23 As shown, the first flexible member 64 faces the first magnet support 41 and the second magnet support 42. By placing the first flexible member 64 on opposite sides of the first magnet support 41 and / or the second magnet support 42, the collision between the first magnet support 41 and / or the second magnet support 42 and the stator is a soft-on-hard collision, thereby improving or resolving impact noise and avoiding the generation of small particles.

[0190] Figure 24 A three-dimensional structural diagram showing the placement of a second flexible element on the coil support. Figure 25 This is a cross-sectional schematic diagram showing the cooperation between the second flexible component and the coil support, the first magnet support, and the second magnet support.

[0191] During the operation of the anti-shake motor 123, the mover and stator will collide in the width direction Y of the anti-shake motor 123. Therefore, in some possible implementations, see [link to relevant documentation]. Figure 24 and Figure 25 As shown, the stator also includes a second flexible member 65, which is fixedly connected to the coil support 61. The mover has second flexible members 65 on both opposite sides along the width direction Y of the anti-vibration motor 123. By providing the second flexible member 65 between the mover and stator, when the mover moves towards the stator along the width direction Y of the anti-vibration 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.

[0192] The specific material of the second flexible member 65 is not limited here. For example, the second flexible member 65 can be silicone.

[0193] In some implementations, such as Figure 25As shown, 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.

[0194] It should be noted that, in addition to being integrated onto the stator, the second flexible component 65 can also be integrated onto the mover in some scenarios. Integrating the second flexible component 65 onto the stator can reduce the weight of the mover and simplify its movement.

[0195] During the operation of the anti-shake motor 123, the specific parts where the moving part and the stator 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... Figure 25 As shown, the second flexible member 65 faces the second magnet support 42. By placing the second flexible member 65 on opposite sides of the first magnet support 41 and / or the second magnet support 42, the collision between the first magnet support 41 and / or the second magnet support 42 and the stator is a soft-on-hard collision, thereby improving or resolving the impact noise and avoiding the generation of small particles.

[0196] For example, such as Figure 25 As shown, the coil bracket 61 collides with the connecting plate 422 of the second magnet bracket 42. Therefore, the second flexible member 65 faces the connecting plate 422 of the second magnet bracket 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 bracket 61 and the connecting plate 422, and less than the distance between the coil bracket 61 and the first magnet bracket 41.

[0197] 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:

[0198] 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.

[0199] To reduce the background noise caused by the low-stiffness coil support 61, the following measures can be taken:

[0200] Figure 26 for Figure 3 A first-view diagram showing the connection between the coil support and the outer casing. Figure 27 for Figure 3 A second-view diagram showing the connection between the coil support and the outer casing.

[0201] In some possible implementations, such as Figure 13 As shown, the outer shell 62 is located on the side of the coil support 61 away from the stationary platform 321 along the thickness direction Z of the anti-shake motor 123. The outer shell 62 is welded to the coil support 61. Specifically, the outer shell 62 is welded to the first metal bracket 611 of the coil support 61. By supporting the coil support 61 through the outer shell 62, the rigidity of the coil support 61 can be increased, which can effectively reduce the background noise problem caused by the low rigidity of the coil support 61 and achieve the purpose of optimizing the operating background noise.

[0202] The specific welding position between the first metal bracket 611 and the outer casing 62 is not limited here. For example... Figure 26 As shown, there are three welding positions (e.g., between one side of the housing 62 and the first metal bracket 611, spaced apart along the length of the anti-shake motor 123) Figure 26(As shown in H1, H2 and H3), there are three welding positions (e.g., between the other side of the housing 62 and the first metal bracket 611, spaced apart along the length of the anti-shake motor 123) Figure 27 (As shown in H4, H5 and H6).

[0203] Figure 28 for Figure 7 A three-dimensional structural diagram of the first metal support in the diagram.

[0204] In some possible implementations, such as Figure 28 As shown, 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.

[0205] Figure 29 for Figure 3 A first-view schematic diagram showing the connection between the coil support and the cover plate. Figure 30 for Figure 3 A second-view diagram showing the connection between the coil support and the cover plate.

[0206] In some possible implementations, such as Figure 29 As shown, the coil support 61 includes a first metal support 611 and a first plastic part 612. Wherein, as... Figure 28 As shown, the first metal bracket 611 includes a metal main body 6111 and a metal bending portion 6112. At least a portion of the metal main body 6111 is embedded inside the first plastic part 612, and the metal bending portion 6112 is fixedly connected to the cover plate 10. By bending the first metal bracket 611 to form the metal bending portion 6112 connected to the second metal bracket 12 of the cover plate 10, the rigidity of the first metal bracket 611 can be improved, thereby improving the rigidity of the first plastic part 612. As a result, the coil bracket 61 has high rigidity, which can effectively reduce the background noise problem caused by the low rigidity of the coil bracket 61.

[0207] Combination Figure 29 and Figure 30 It can be seen that 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.

[0208] Typically, during the assembly of the image stabilization motor 123, the presence of tiny particles inside the motor can cause a partilcle problem. This partilcle problem affects the operation of the actuator and / or the light-sensing performance 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:

[0209] Figure 31 for Figure 3 A three-dimensional structural diagram of the outer shell.

[0210] In some possible implementations, such as Figure 31 As shown, the outer casing 62 serves as part of the cavity wall of the receiving chamber and has a water washing hole 63, which communicates with the interior of the receiving chamber. 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 the use of deionized water, compressed air, or a suitable cleaning agent to clean the interior, directly removing particles adhering to the mover, stator, and suspension wire 322. Therefore, through the rational design of the 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.

[0211] 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.

[0212] 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.

[0213] In some embodiments, as shown in the figure, the water rinsing 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 rinsing 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 rinsing hole 63 may also be located on the portion of the housing 62 along the thickness direction Z of the anti-shake motor 123 opposite to the first magnet bracket 41.

[0214] 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.

[0215] 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 and stator 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.

[0216] The specific type of colloidal component is not limited here. For example, the colloidal component can be a dust-repairing adhesive.

[0217] 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.

[0218] 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 the 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. Specifically, 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.

[0219] 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.

[0220] 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.

[0221] 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. The number of first damping elements 66 can be one or more, for example, two. The number of second damping elements 67 can be one or more, for example, two. The number of third damping elements 68 can be one or more, for example, two.

[0222] Figure 32 for Figure 16A cross-sectional schematic diagram of the first damping element cooperating with the first magnet support.

[0223] like Figure 32 As shown, Figure 32 As shown, along the thickness direction Z of the anti-shake motor 123, the first damping member 66 is located between the support body 421 of the first magnet bracket 41 and the second magnet bracket 42. One end of the first damping member 66 contacts the first magnet bracket 41, and the other end of the first damping member 66 contacts the coil circuit board assembly 50 or the coil bracket 61. Specifically, as... Figure 32 As shown, there are two first damping elements 66. One of the first damping elements 66 has its two ends in contact with the first magnet bracket 41 and the second reinforcing plate 55 of the coil circuit board assembly 50, respectively. The other first damping element 66 has its two ends in contact with the first magnet bracket 41 and the coil bracket 61, respectively.

[0224] It should be noted that the specific parts that contact the coil circuit board assembly 50 with the first damping component 66, in addition to the second reinforcing plate 55, can also be the shielding cover 53, the first coil 56, the second coil 57, the coil circuit board 51, etc.

[0225] The first damping element 66 is made of damping material, such as silicone rubber, polyurethane, thermoplastic elastomer, or other damping adhesives (also known as shock absorbers or cushioning materials). The first damping element 66 can help reduce unnecessary vibrations, impacts, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing its control performance.

[0226] The specific structure of the first damping element 66 is not limited here. For example... Figure 16 As shown, the first damping element 66 can be cylindrical.

[0227] Figure 33 A schematic diagram of the pavement in which the second damping element cooperates with the outer shell and the first magnet support.

[0228] like Figure 33 As shown, along the thickness direction Z of the anti-shake motor 123, the second damping element 67 is located between the housing 62 and the first magnet bracket 41, with both ends of the second damping element 67 contacting the housing 62 and the first magnet bracket 41, respectively. Specifically, as... Figure 33 As shown, there are two second damping elements 67, and the two second damping elements 67 are arranged at intervals along the length direction X of the anti-shake motor 123.

[0229] The second damping element 67 is made of damping material, such as silicone rubber, polyurethane, thermoplastic elastomer, or other damping adhesives (also known as shock absorbers or cushioning materials). The second damping element 67 can help reduce unnecessary vibrations, impacts, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing its control performance.

[0230] The specific structure of the second damping element 67 is not limited here. For example, the second damping element 67 can be cylindrical.

[0231] In some embodiments, as shown in the figure, the first magnet bracket 41 is provided with a first groove (not shown in the figure) on the side of the anti-shake motor 123 facing the housing 62 along the thickness direction Z, which can accommodate a portion of the second damping member 67, thereby positioning the second damping member 67 and increasing the size of the second damping member 67 in the thickness direction Z of the anti-shake motor 123.

[0232] Figure 34 This is a cross-sectional schematic diagram showing the cooperation between the third damping element, the coil support, and the second magnet support. Figure 35 for Figure 34 Enlarged schematic diagram of point M in the middle.

[0233] like Figure 35 As shown, along the thickness direction Z of the anti-shake motor 123, the third damping element 68 is located between the second magnet bracket 42 and the coil bracket 61, and the two ends of the third damping element 68 are in contact with the coil bracket 61 and the second magnet bracket 42, respectively.

[0234] The third damping element 68 is made of damping material, such as silicone rubber, polyurethane, thermoplastic elastomer, or other damping adhesives (also known as shock absorbers or cushioning materials). The third damping element 68 can help reduce unnecessary vibrations, impacts, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing its control performance.

[0235] The specific structure of the third damping element 68 is not limited here. For example, the third damping element 68 can be cylindrical.

[0236] In some embodiments, as shown in the figure, the second magnet bracket 42 is provided with a second groove (not shown in the figure) on the side of the coil bracket 61 along the thickness direction Z of the anti-shake motor 123 to accommodate the third damping member 68. This groove can position the third damping member 68 and increase the size of the third damping member 68 in the thickness direction Z of the anti-shake motor 123.

[0237] In some possible implementations, such as Figure 23As shown, 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 component 43 and the second magnetic sheet 413. The first magnet component 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, which requires a fast response.

[0238] In some possible implementations, such as Figure 23 As shown, the stator also 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 that there is a magnetic attraction between them. At the same time, 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. In addition, the Helbeck magnet array combined with the dual magnetic sheets forms a strong magnetic attraction structure, which is not sensitive 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, which facilitates assembly and debugging. Therefore, there is no need to set a separate magnetic sheet to cooperate with the third magnet 45.

[0239] The third magnet component 45 may include one or more third magnets, which is not limited here.

[0240] For example, such as Figure 23 As shown, the third magnet 45 can be fixed to the inner wall of the outer casing 62, for example, the third magnet 45 is bonded to the inner wall of the outer casing 62.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal connection of two components or the interaction between two components.
