Description

Technical Field

[0001] The present application relates to the field of camera technology, and in particular to an anti-shake motor, a camera module and an electronic device. Background Art

[0002] With the popularity of electronic devices such as smartphones and tablets, users have higher and higher requirements for the shooting quality of electronic devices. When using electronic devices for shooting operations, the shaking of the electronic devices is difficult to avoid, which will seriously affect the shooting quality. Therefore, an anti-shake structure needs to be set in the camera module. In the related art, the camera anti-shake solution is image sensor displacement optical image stabilization, which drives the image sensor to move through the anti-shake motor and adjusts the specific position and posture of the image sensor to achieve the purpose of shake correction. However, the reliability of the anti-shake motor in the related art is low, and the risk of failure of the anti-shake motor is high. Summary of the Invention

[0003] The embodiments of the present application provide an anti-shake motor, a camera module, and an electronic device, wherein the anti-shake motor has high reliability.

[0004] In a first aspect, an embodiment of the present application provides an anti-shake motor, which includes a suspension wire, a stator, and a mover. The stator includes a fixed platform and an avoidance gap. The avoidance gap is located on the side of the fixed platform facing the suspension wire in a direction perpendicular to the thickness direction of the anti-shake motor. The avoidance gap penetrates the fixed platform in the thickness direction of the anti-shake motor, and the avoidance gap is used to avoid the suspension wire. The mover is used to carry an image sensor. The suspension wire is connected between the mover and the fixed platform. Along a direction perpendicular to the thickness direction of the anti-shake motor, the center of gravity of the mover is located between the avoidance gap and the geometric center of the mover. The center of gravity and the geometric center of the mover are spaced apart.

[0005] During operation, all moving parts of the image stabilization motor, except for the suspension wire, constitute the mover, while the remaining stationary parts, except for the suspension wire, constitute the stator. The mover drives the image sensor to translate or rotate, enabling image sensor jitter suppression in three directions: X-axis translation, Y-axis translation, and Z-axis rotation. This solves problems such as optical image instability and image rotation, and improves image quality.

[0006] In addition, during the reliability test of the anti-shake motor or the accidental drop or collision of the electronic device, since the center of gravity and the geometric center of the mover do not coincide, the mover is likely to move in a direction perpendicular to the thickness direction of the anti-shake motor, causing the suspension wire to collide with the fixed table in this direction, and the suspension wire is stuck and squeezed by the fixed table, and the suspension wire is easily damaged, that is, the failure risk of the suspension wire is high and the reliability of the suspension wire is low. In view of this, the embodiment of the present application sets an avoidance gap on the fixed table to avoid the suspension wire, thereby preventing the suspension wire from colliding or being squeezed with the fixed table, reducing the failure risk of the suspension wire, making the suspension wire highly reliable, and thus the anti-shake motor highly reliable. In addition, it can also avoid the generation of tiny particles caused by the collision of the suspension wire with the fixed table, thereby improving the performance of the anti-shake motor.

[0007] In addition, compared with the traditional technology of reducing the failure risk of the suspension wire by increasing the width of the spacing space, the avoidance gap is used to reduce the failure risk of the suspension wire without increasing the width of the spacing space. The spacing width between the mover and the fixed table can be designed to be small, so that the size of the anti-shake motor in the direction perpendicular to the thickness direction of the anti-shake motor is smaller, 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 shielding cover. The integrated circuit is electrically connected to one side of the coil circuit board. The shielding cover includes a shielding body and a lug plate. The shielding body and the lug plate are located on the same side of the coil circuit board. The shielding body and the coil circuit board enclose a space for accommodating the integrated circuit. One end of the lug plate is fixedly connected to the shielding body. The lug plate is located outside the space and affixed to the coil circuit board.

[0009] Typically, the coil circuit board is a flexible circuit board. When the anti-shake motor shakes or the mover collides with the stator, the coil circuit board is affected by the stress and deforms. If the coil circuit board deforms too much, it will cause the solder joints between the integrated circuit (IC) and the coil circuit board to fall off. To this end, the support lugs are attached to the coil circuit board to enhance the strength of the coil circuit board, prevent excessive deformation of the coil circuit board, and prevent the solder joints between the coil circuit board and the IC from falling off. In addition, the IC is located within the shield body, which can also transfer stress near the IC from the coil circuit board to the support lugs, preventing the coil circuit board near the IC from deforming too much and preventing the solder joints between the IC and the coil circuit board from falling off.

[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 a side of the coil circuit board away from the integrated circuit, with at least a portion of the orthographic projection of the integrated circuit on the coil circuit board located within the orthographic projection of the first reinforcing plate on the coil circuit board.

[0011] Typically, the coil circuit board is a flexible circuit board. When the anti-shake motor shakes or the mover collides with the stator, the coil circuit board deforms due to stress. Excessive deformation can cause the solder joints between the integrated circuit (IC) and the coil circuit board to break. To address this issue, a first reinforcement plate is installed on the side of the coil circuit board away from the IC. The first reinforcement plate at least partially overlaps the orthographic projection of the IC on the coil circuit board. This improves the strength of the connection between the coil circuit board and the IC, preventing excessive deformation of the coil circuit board and preventing solder joints from breaking.

[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 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 is fixedly connected to the first magnet bracket. The connecting plate is provided with a rib structure.

[0013] The first magnet bracket and the second magnet bracket are both used to carry magnets. The magnets cooperate with the coils of the stator to generate a driving force, so that the mover moves relative to the stator, thereby driving the image sensor to move and realizing optical image stabilization. Usually, the second magnet bracket is made of metal and plastic materials to reduce the weight of the second magnet bracket, which helps to achieve a lightweight design of the anti-shake motor. Therefore, the connecting plate body is made of metal and plastic materials, and the strength of the connecting plate body is relatively low. The connecting plate body is easily deformed after colliding with the stator. To this end, the embodiment of the present application provides a rib structure forming reinforcing ribs on the connecting plate body, so that the connecting plate body has high strength and reduces the risk of deformation of the connecting plate body.

[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 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 width of the connecting plate in the width direction of the anti-shake motor gradually decreases along the direction from the bracket body to the first magnet bracket. Both end surfaces of the connecting plate in the width direction of the anti-shake motor are inclined surfaces in the thickness direction of the anti-shake motor.

[0015] Typically, the second magnet bracket is made of metal and plastic to reduce its weight and achieve a lightweight design for the anti-shake motor. Therefore, the connecting plate is made of metal and plastic, which has low strength and is easily deformed after colliding with the stator. To this end, a draft design is applied to 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 reducing the risk of deformation of the connecting plate.

[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. The other end of the connecting plate includes a second metal portion. The second metal portion is welded to the first metal portion. Along the length direction of the anti-shake motor, at least part of the orthographic projection of the portion of the second metal portion opposite to the first metal portion on the first metal portion is located inside the first metal portion.

[0017] Typically, the first and second magnet brackets are constructed of metal and plastic to reduce the weight of the second magnet bracket and achieve a lightweight anti-shake motor design. Consequently, the connecting plate, constructed of metal and plastic, has low strength and is susceptible to deformation upon collision with the stator. Therefore, positioning at least a portion of the orthographic projection of the second metal portion onto the interior of the first metal portion increases the weld width between the first and second metal portions, improving the connecting plate's resistance to deformation.

[0018] In a possible implementation, center lines of the first metal portion and the second metal portion in the width direction of the anti-shake motor coincide with each other.

[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 arranged, so that the welding width of the first metal part and the second metal part can be maximized, further improving the deformation resistance of the connecting plate body.

[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. At least a portion of the end surface of the connecting plate facing the stator along the length of the anti-shake motor is made of metal.

[0021] Typically, the first magnet bracket and the second magnet bracket are both made of metal and plastic materials to reduce the weight of the second magnet bracket and achieve a lightweight design of the anti-shake motor. During the movement of the anti-shake motor, the part where the second magnet bracket collides with the stator is the connecting plate. The surface material of the connecting plate colliding with the stator is plastic. Due to the low strength of plastic, the plastic is easily damaged after multiple collisions, causing the connecting plate to deform. Therefore, the embodiment of the present application exposes the metal material in the connecting plate so that the surface material of the connecting plate colliding with the stator is metal. The high strength of metal makes the connecting plate highly resistant 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 fixed platform. The housing is located on a side of the coil support away from the fixed platform along the thickness direction of the anti-shake motor, and the housing is welded to the coil support.

[0023] Typically, a coil support is constructed from a metal frame and plastic components, resulting in low rigidity. This low rigidity can lead to noise floor issues. To address this, the present embodiment welds the outer shell to the coil support's metal frame, using the outer shell to support the coil support, increasing its rigidity and optimizing the noise floor.

[0024] In a possible implementation, the stator further includes a coil bracket, the coil bracket includes a first metal bracket and a first plastic part, the first metal bracket is an integrated structure, and the first metal bracket is fixedly connected to the first plastic part.

[0025] Typically, a coil support is composed of a metal frame and plastic parts, resulting in low rigidity. This low rigidity can lead to noise floor issues. Therefore, the present embodiment utilizes a first metal support with an integrated structure as the metal frame. This high rigidity increases the rigidity of the first plastic part, improving the rigidity of the coil support and thus optimizing the 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 through hole for light to pass through. The coil support includes a first metal support and a first plastic component. The first metal support includes a metal main portion and a metal bent portion. The metal main portion is at least partially embedded within the first plastic component, and the metal bent portion is fixedly connected to the cover plate.

[0027] Typically, coil supports are constructed from a metal frame and plastic components, resulting in low rigidity. This low-rigidity wire weight support can lead to noise floor issues. To address this issue, bending the first metal support to form a metal bend that connects to the cover plate increases the rigidity of the first metal support, thereby increasing the rigidity of the first plastic component and, consequently, the coil support, ultimately optimizing the noise floor.

[0028] In one possible implementation, the stator includes a housing and a shell. The mover is located within the housing. The shell serves as a partial wall of the housing and has a water washing hole that communicates with the interior of the housing.

[0029] Often, during the assembly process of an image stabilization motor, tiny particles can accumulate inside it, creating a particle problem. This can affect the operation of the actuator and / or the sensitivity of the image sensor, resulting in poor image quality. To address this, a water flushing hole is provided on the housing to clean the interior of the image stabilization motor, removing particles, dust, and other foreign matter, thereby improving or resolving the particle problem. The "particle" problem generally refers to the impact of tiny particles on motor performance.

[0030] In a possible implementation, along the thickness direction of the anti-shake motor, the distance between the water washing hole and the bottom surface of the housing away from the suspension wire is less than or equal to one third of the thickness of the anti-shake motor.

[0031] In this implementation, the distance between the water washing hole and the bottom surface of the shell is less than or equal to one-third of the thickness of the motor, which can reduce the difficulty of discharging cleaning media such as liquid or gas used in the water washing process from the anti-shake 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 colloid. The cover plate is fixedly connected to the coil support. The coil circuit board assembly is fixedly connected to the coil support. The colloid is provided on a surface of at least one of the coil support, the cover plate, and the coil circuit board assembly.

[0033] In this implementation, the viscosity of the colloid component is used to absorb tiny particles inside the anti-shake motor, thereby improving the particulate problem.

[0034] In a possible implementation, the stator further includes a first flexible member, and the first flexible member is provided on both opposite sides of the mover along the length direction of the anti-shake motor.

[0035] During operation, the mover and stator of the anti-shake motor collide along its length. This hard collision produces unusual noise and may generate tiny particles, impacting the reliability of the anti-shake motor and the image quality of the image sensor. To address this, a first flexible member is installed between the mover and stator. As the mover moves toward the stator along the length of the anti-shake motor, it collides with the first flexible member. This first flexible member acts as a buffer, reducing or eliminating the unusual noise and preventing the generation of tiny 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 anti-shake motor, and along the length direction of the anti-shake motor, the first flexible member faces at least one of the first magnet bracket and the second magnet bracket.

[0037] During the operation of the anti-shake motor, the specific parts where the mover and the stator collide in the length direction of the anti-shake motor are usually the first magnet bracket and / or the second magnet bracket. Therefore, the first flexible part is arranged on opposite sides of the first magnet bracket and / or the second magnet bracket so that the first magnet bracket and / or the second magnet bracket collides with the first flexible part, thereby reducing or solving the abnormal impact noise and avoiding the generation of tiny particles.

[0038] In a possible implementation, the stator further includes a second flexible member, and the second flexible member is provided on both opposite sides of the mover along the width direction of the anti-shake motor.

[0039] During operation, the mover and stator of the anti-shake motor collide hard across the motor's width. This collision produces both unusual noise and the generation of small particles, which can affect the motor's reliability and the image quality of the image sensor. To address this, a second flexible member is installed between the mover and stator. As the mover moves toward the stator along the motor's width, it collides with the second flexible member. This second flexible member acts as a buffer, reducing or eliminating the unusual noise and preventing the generation of small particles.

[0040] In one possible implementation, the stator further includes a coil bracket, the second flexible member being fixedly connected to the coil bracket. The mover further includes a first magnet bracket and a second magnet bracket, and the second flexible member faces at least one of the first magnet bracket and the second magnet bracket 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 the stator collide in the width direction of the anti-shake motor are usually the first magnet bracket and / or the second magnet bracket. Therefore, the second flexible part is arranged on opposite sides of the first magnet bracket and / or the second magnet bracket, so that the first magnet bracket and / or the second magnet bracket collides with the second flexible part, reducing or solving the abnormal impact noise and avoiding the generation of tiny 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 respectively fixedly connected to the coil bracket. The anti-shake motor further includes at least one of the following damping members: a first damping member, a second damping member, and a third damping member. The first damping member is located between the first and second magnet brackets along the thickness of the anti-shake motor, one end of the first damping member contacts the first magnet bracket, and the other end of the first damping member contacts the coil circuit board assembly or the coil bracket. The second damping member is located between the housing and the first magnet bracket along the thickness of the anti-shake motor, with both ends of the second damping member contacting the housing and the first magnet bracket, respectively. The third damping member is located between the second magnet bracket and the coil bracket, with both ends of the third damping member contacting the coil bracket and the second magnet bracket, respectively.

[0043] In this implementation, by providing at least one of the first damping member, the second damping member, and the third damping member, the damping characteristics of the damping material are utilized, which helps to improve the control performance of the anti-shake motor.

[0044] In one possible implementation, the mover further includes a first magnetic member and a first magnetic bracket, the first magnetic bracket includes a first magnetic conductive sheet and a second magnetic conductive sheet, the first magnetic conductive sheet is located between the first magnetic member and the second magnetic conductive sheet, and the first magnetic member is a Halbach magnet array.

[0045] In this implementation, the Halbach magnet array combined with the dual-magnetic plate design achieves low restoring force. This means that when the stabilization motor is de-energized, the interaction between the magnets is reduced, reducing rebound or vibration and improving control precision. Low restoring force helps the stabilization motor reach the target position and stabilize more quickly, which is particularly important for stabilization motors that require fast response.

[0046] In one possible implementation, the stator also includes: a third magnetic component, which is located on the side of the second magnetic conductive sheet away from the first magnetic conductive sheet along the thickness direction of the anti-shake motor and is spaced apart from the second magnetic conductive sheet, and the third magnetic component is magnetically connected to the second magnetic conductive sheet.

[0047] In this implementation, the third magnet is magnetically connected to the second magnetic conductive sheet, creating a magnetic attraction between them. Furthermore, because the third magnet remains in place, this magnetic attraction pulls the first magnet holder, preventing it from accidentally moving toward the image sensor.

[0048] In a second aspect, an embodiment of the present application provides a camera module, which includes a lens, an image sensor, and an anti-shake motor as described in any one of the first aspects, wherein the image sensor is located on the light-emitting side of the lens, and the image sensor is fixedly connected to the actuator of the anti-shake motor.

[0049] In a third aspect, an embodiment of the present application provides an electronic device, which includes a housing and a camera module as described in the second aspect, wherein the camera module is installed in the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] In the embodiment of the present application, a mobile phone is taken as an example of the electronic device 100 to specifically illustrate the structures of the electronic device 100 and the camera module 120 .

[0106] Figure 1 This is a schematic diagram of an explosion of an electronic device provided in an embodiment of the present application.

[0107] See also 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. The housing 110 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 respectively connected to the middle frame 111. The middle frame 111, back cover 112, and display screen 130 enclose a cavity that accommodates components such as a battery 140, the camera module 120, and the battery 140.

[0108] Among them, the number of camera modules 120 can be one, or the number of camera modules 120 can be multiple to meet different shooting needs.

[0112] See also Figure 2 As shown, the camera module 120 includes a lens 121, an image sensor 122, and an anti-shake motor 123. The image sensor 122 is located on the light-emitting side of the lens 121 and is fixedly connected to the anti-shake motor 123. When the electronic device 100 is shooting, the anti-shake motor 123 is used to drive the image sensor 122 to move, so that the image sensor 122 can achieve jitter suppression in three directions: X-axis translation, Y-axis translation, and Z-axis rotation (within the XY plane). This solves problems such as optical image instability and image rotation, achieves optical image stabilization, and improves shooting quality.

[0113] In related technologies, an anti-shake motor consists of a stator, a mover, and a suspension wire. The mover is fixedly connected to the image sensor, and the suspension wire is connected between the stator and the mover. During reliability testing of the anti-shake motor or when the electronic device is accidentally dropped or collided, the suspension wire can easily become stuck in the stator and be squeezed, causing damage to the suspension wire. This indicates that the reliability of the anti-shake motor is low, resulting in a high risk of failure.

[0114] After careful analysis, the inventors of this application discovered that one reason the suspension wire gets stuck in the stator is that the center of gravity and geometric center of the mover do not coincide. In other words, the mover's center of gravity is offset, making it prone to movement in a direction perpendicular to the thickness direction Z of the anti-shake motor. This causes the suspension wire to collide with the stator in this direction, resulting in the suspension wire being stuck and squeezed by the stator, which easily damages the suspension wire. This means that the suspension wire has a high risk of failure and low reliability. Furthermore, the collision between the suspension wire and the stator easily generates tiny particles, causing a particle problem that can affect the performance of the anti-shake motor and the image quality of the image sensor. The "particle" problem generally 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 mover's direction of motion to prevent the suspension wire from colliding with the stator and preventing failure. However, this approach results in a larger distance between the mover and stator, which increases the size of the anti-shake motor and makes it difficult to miniaturize it. Therefore, how to improve the reliability of the anti-shake motor without increasing its size has become a pressing issue.

[0116] In view of this, the present embodiment provides an anti-shake motor 123. By providing a relief notch 325 at a location on the stator that is likely to come into contact with the suspension wire 322, this notch allows for the suspension wire 322 to avoid being caught and squeezed by the stator. This improves the reliability of the suspension wire 322 and reduces the risk of failure, thereby enhancing the reliability of the anti-shake motor 123. Furthermore, the relief notch 325 improves the reliability of the suspension wire 322 without increasing the size of the anti-shake motor 123, helping to achieve a compact anti-shake motor 123 while maintaining high reliability and alleviating component issues.

[0117] The anti-shake motor 123 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0118] Figure 3 This is a schematic diagram of the three-dimensional structure of the anti-shake motor provided in an embodiment of the present application. Figure 4 for Figure 3 The cross-sectional diagram of the anti-shake motor from the first perspective is shown.

Figure 6 for Figure 3 Schematic diagram of the three-dimensional structure of the coil support, Figure 7 for Figure 6 The exploded view of the coil support is shown. Figure 8 for Figure 3 Schematic diagram of the three-dimensional structure of the cover plate.

[0119] In the embodiment of the present application, the anti-shake motor 123 includes a cover 10 (cover), a main circuit board assembly 30, a filter holder 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 43, a second magnet 44, a coil circuit board assembly 50 and a housing 62 (case). Figure 3 As shown, along the thickness direction Z of the anti-shake motor 123, the cover 10 is located on one side of the coil bracket 61 and is fixedly connected to the coil bracket 61, and the shell 62 is located on the other side of the coil bracket 61 and is fixedly connected to the coil bracket 61. The cover 10, the coil bracket 61 and the shell 62 can together form a layout space, which is used to accommodate 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 part 43, the second magnet part 44, the filter carrier 20, the filter, the image sensor 122 and other devices.

[0120] In order to effectively balance the strength and weight of the coil support 61, Figure 6 and Figure 7As can be seen, the coil support 61 may include a first metal support 611 and a first plastic part 612. The first metal support 611 serves as a metal skeleton of the coil support 61. At least a portion of the first metal support 611 is embedded in the first plastic part 612. For example, a portion of the first metal support 611 is disposed in the first plastic part 612.

[0121] The first metal bracket 611 and the first plastic part 612 are combined together 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 also Figure 8 As shown, the cover plate 10 has a light-transmitting through hole 11. The light-transmitting through hole 11 is located on the photosensitive side of the image sensor 122 and is arranged opposite to the photosensitive surface of the image sensor 122. The light-transmitting through hole 11 is used to allow 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 welding, clamping, threading, etc., for example Figure 3 As shown, the cover plate 10 is welded to the coil support 61. In some embodiments, in order to effectively balance the strength and weight of the cover plate 10, as shown in FIG. 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 is fixedly connected to the second plastic part 13. The second metal bracket 12 may have a mesh structure. The second metal bracket 12 and the second plastic part 13 may be integrally formed by injection molding. The second metal bracket 12 is welded to the first metal bracket 611 of the coil support 61.

[0123] Figure 9 for Figure 3 A top view of the main circuit board assembly in FIG. Figure 10 for Figure 9 A cross-sectional diagram of the main circuit board and the carrier circuit board in FIG. Figure 11 for Figure 10 Schematic diagram of the three-dimensional structure of the main circuit board, Figure 12 for Figure 11 The schematic diagram of the top view of the main circuit board is shown.

[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. 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 outside the movable platform 323, and there is a spacing space 324 between the fixed platform 321 and the movable platform 323. The suspension wire 322 is located in the spacing space 324. 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 fixed platform 321 is located between the coil support 61 and the cover 10. Figure 10 As shown, one side of the movable platform 323 is mechanically and electrically connected to the carrier circuit board 33. Figure 5 As shown, the other side of the movable table 323 is fixedly connected to the second magnet bracket 42. During the operation of the anti-shake motor 123, the fixed table 321 remains stationary, the movable table 323 moves relative to the fixed table 321, and the suspension wire 322 is deformed under the driving action of the movable table 323.

[0125] The specific structure of the suspension wire 322 is not limited here. Figure 12 As shown, the suspension wire 322 includes two flexible connection structures 3221, each flexible connection structure 3221 includes a connection portion 3223 and a plurality of strip portions 3222, the plurality of strip portions 3222 are arranged at intervals along a direction perpendicular to the thickness direction Z of the anti-shake motor 123, and two adjacent strip portions 3222 are connected by a connection portion 3223, one end of each strip portion 3222 is connected to the moving table 323, and the other end of each strip portion 3222 is connected to the fixed table 321.

[0126] like Figure 12 As shown, the two flexible connection structures 3221 are respectively a first flexible connection structure 3221a and a second flexible connection structure 3221b. One end of the strip portion 3222 of the first flexible connection structure 3221a and one end of the strip portion 3222 of the second flexible connection structure 3221b are respectively connected to opposite sides of the movable platform 323, while the other ends of the strip portion 3222 of the first flexible connection structure 3221a and the other ends of the strip portion 3222 of the second flexible connection structure 3221b are respectively connected to opposite sides of the fixed platform 321.

[0127] There is no specific limitation on the specific number of the strip portions 3222. 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 annular structure. Of course, the fixed platform 321 can also be an unclosed quasi-annular 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 further includes a connector 71, which is located between the movable platform 323 and the second magnet bracket 42. The orthographic projection of the connector 71 on the movable platform 323 is located inside the movable platform 323. The connector 71 is fixedly connected to the movable platform 323 and the second magnet bracket 42, respectively. The movable platform 323 is fixedly connected to the second magnet bracket 42 via the connector 71. Of course, in some embodiments, the movable platform 323 can also be directly connected to the second magnet bracket 42, for example, by bonding the movable platform 323 to the second magnet bracket 42.

[0131] The first end of the external circuit board 31 is electrically connected to the end surface of the fixed base 321 of the main circuit board 32. The external circuit board 31 is used to electrically connect to the processor on the mainboard of the electronic device 100. The external circuit board 31 may be a flexible circuit board. In some embodiments, the external circuit board 31 is located outside the layout space. In other embodiments, a portion of the external circuit board 31 may be located inside the layout space, while another portion is located outside the layout space.

[0132] like Figure 10 As shown, the carrier circuit board 33 is stacked with the main circuit board 32. The carrier circuit board 33 is mechanically and electrically connected to the movable platform 323 of the main circuit board 32. 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 via the carrier circuit board 33. The image sensor 122 and the main circuit board 32 are respectively located on either side of the carrier circuit board 33.

[0133] Figure 13 for Figure 3 A cross-sectional schematic diagram of the anti-shake motor from a third perspective is shown.

[0134] In order to improve the stability of the movement of the image sensor 122, in some embodiments, 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 via the spacing space 324. To further enhance the connection between the carrier circuit board 33 and the second magnet bracket 42, in some embodiments, the connector 4211 can include a main connecting portion and a connecting rod portion, wherein the main connecting portion is bonded to the carrier circuit board 33 and the connecting rod portion is inserted into a through hole in the carrier circuit board 33.

[0135] like Figure 13As shown, the filter holder 20 is fixedly connected to the side of the carrier circuit board 33 away from the main circuit board 32. The filter holder 20 can be bonded to the carrier circuit board 33. The filter holder 20 is used to support a filter (not shown in the figure). In this case, the filter is arranged opposite the image sensor 122 and is located on the photosensitive side of the image sensor 122. The filter can be bonded to the filter holder 20. The filter holder 20 can be a frame structure, surrounding the filter without blocking the image sensor 122.

[0136] After light from outside the camera module 120 enters the optical components within the anti-shake motor 123, it passes through the optical filter and image sensor 122, ultimately converting the light signal into an image target signal under the action of the image sensor 122. The optical filter can filter out certain wavelengths of light, allowing only certain wavelengths of light to pass through, and can also provide some protection for the image sensor 122. For example, the optical filter can be an infrared filter, which can filter out light in the infrared band while allowing light in other bands to pass through.

[0137] Figure 14 for Figure 4 Schematic diagram of the three-dimensional structure of the first magnet bracket, the second magnet bracket and the first magnet component.

[0138] like Figure 14 As shown, the first magnetic member 43 is fixedly connected to the first magnetic bracket 41, and the first magnetic member 43 may include one or more first magnets. Figure 13 As shown, the second magnetic member 44 is fixedly connected to the second magnetic bracket 42. The second magnetic member 44 may include one or more second magnets. The first magnetic member 43 and the second magnetic member 44 are both used to interact with the coil in the coil circuit board assembly 50 to generate a driving force to drive the image sensor 122 to move.

[0139] like Figure 14 As shown, the first magnet bracket 41 is fixedly connected to the second magnet bracket 42, and at least a portion of the second magnet bracket 42 is spaced apart from the first magnet bracket 41 along the thickness direction Z of the anti-shake motor 123, for example Figure 4 As shown, the second magnet support 42 and the first magnet support 41 are spaced apart from each other 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 an annular structure. At this time, the coil circuit board assembly 50 is located inside the annular structure surrounded 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 control the weight of the first magnet bracket 41 and the second magnet bracket 42, the first magnet bracket 41 and the second magnet bracket 42 are both made of metal and plastic. The metal material constitutes 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 Schematic diagram of the three-dimensional structure of the second magnet bracket.

[0142] In order to achieve the fixed connection between the first magnet bracket 41 and the second magnet bracket 42, as shown in FIG. Figure 15 As shown, the second magnet bracket 42 includes a bracket body 421 and two connecting plates 422. Figure 4 As shown, the bracket body 421 and the first magnet bracket 41 are spaced apart along the thickness direction Z of the anti-shake motor 123. The bracket body 421 is located between the main circuit board 32 and the coil bracket 61. The bracket body 421 is fixedly connected to the movable table 323 of the main circuit board 32. Two connecting plates 422 are located at opposite ends of the bracket body 421 in 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 bracket 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 bracket 41 is located between the housing 62 and the coil bracket 61. In order to connect the first magnet bracket 41 and the second magnet bracket 42, in some embodiments, as shown in FIG. 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. 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, and the connecting plate 422 passes through the through hole and is fixedly connected to the first magnet bracket 41. The through space 613 corresponds to the connecting plate 422 one by one, for example Figure 4 As shown, the number of the connecting plates 422 is two, and correspondingly, the number of the through spaces 613 is two.

[0144] Figure 16 for Figure 3 A schematic diagram of the three-dimensional structure of the coil circuit board assembly in the first perspective, Figure 17 for Figure 3 A schematic diagram of the three-dimensional structure of the coil circuit board assembly in the second perspective, Figure 18 for Figure 16The cross-sectional view of the coil circuit board assembly shown in FIG. Figure 19 for Figure 16 Schematic diagram of the three-dimensional structure 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. Figure 4 As shown, the coil circuit board 51 is fixedly connected to the coil support 61 and is 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 shielding cover 53 and the integrated circuit 52 are all located on the side of the coil circuit board 51 away from the main circuit board 32. The first coil 56, the second coil 57 and the integrated circuit 52 are electrically connected to the coil circuit board 51 respectively. The shielding cover 53 is fixedly connected to the coil circuit board 51 and encloses a space for accommodating the integrated circuit 52. Figure 17 As shown, the third coil 58 is located on a 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, Figure 16 As shown, there is one first coil 56 and two second coils 57. Along the length X of the anti-shake 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, Figure 17 As shown, there are two third coils 58 , which interact with the second magnet to generate a driving force for moving 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 hole, the third coil 58 is located inside the mounting 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 the embodiment of the present application, when the anti-shake motor 123 is in operation, all moving parts of the anti-shake motor 123 except the suspension wire 322 are defined as the mover, and all stationary parts of the anti-shake motor 123 except the suspension wire 322 are defined as the stator. Therefore, in the embodiment of the present application, the mover may include but is not limited to the first magnet bracket 41, the second magnet bracket 42, the first magnet member 43, the second magnet member 44, the moving platform 323, the connector 71, the filter carrier 20, the carrier circuit board 33, and other components mentioned above, and the stator may include but is not limited to the coil bracket 61, the coil circuit board assembly 50, the housing 62, the cover 10, the fixed platform 321, and other components mentioned above.

[0150] Among them, see Figure 4 As shown, the stator includes a housing, with the mover and suspension wire 322 both located within the housing. The mover is used to support the image sensor 122, and the suspension wire 322 is connected between the mover and the stator's fixed platform 321. The mover is movably connected to the stator via the suspension wire 322. When the anti-shake motor 123 is operating, 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, allowing the image sensor 122 to achieve jitter suppression in three directions: X-axis translation, Y-axis translation, and Z-axis rotation. This solves problems such as optical image instability and image rotation, and improves imaging quality.

[0151] In an embodiment of the present application, the center of gravity and the geometric center of the mover do not coincide, or the center of gravity of the mover is spaced apart from the geometric center, 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 shape of the object. Therefore, during the reliability test of the anti-shake motor 123 or the accidental drop or collision of the electronic device 100, the mover is likely to move in a direction perpendicular to the thickness direction Z of the anti-shake motor 123, or in other words, move in a direction covering the center of gravity and the geometric center of the mover toward the side where the center of gravity is away from the geometric center, causing the suspension wire 322 to collide with the fixed table 321 in this direction, the suspension wire 322 is stuck and squeezed by the fixed table 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, if Figure 12As shown, the embodiment of the present application provides a relief notch 325 on the fixed platform 321. The relief notch 325 is located on the side of the fixed platform 321 facing the suspension wire 322 in a direction perpendicular to the thickness direction Z of the anti-shake motor 123. The relief notch 325 penetrates the fixed platform 321 in the thickness direction Z of the anti-shake motor 123 and communicates with the spacing space 324. The center of gravity of the mover is located between the relief notch 325 and the geometric center of the mover in a direction perpendicular to the thickness direction Z of the anti-shake motor 123. When the mover moves toward the relief notch 325 in a direction perpendicular to the thickness direction Z of the anti-shake motor 123, the relief notch 325 avoids the suspension wire 322, preventing the suspension wire 322 from contacting the fixed platform 321. This prevents the suspension wire 322 from colliding with or being squeezed by the fixed platform 321, reduces the risk of failure of the suspension wire 322, and improves the reliability of the suspension wire 322, thereby enhancing the reliability of the anti-shake motor 123. In addition, the suspension wire 322 does not collide with the fixed platform 321, thereby preventing the generation of tiny particles.

[0153] In addition, compared with the traditional technology of increasing the width of the spacing space 324 to prevent the suspension wire 322 from colliding with the fixed table 321, the embodiment of the present application sets an avoidance gap 325 for avoiding the suspension wire 322 in the local area where the fixed table 321 collides with the suspension wire 322, thereby reducing the failure risk of the suspension wire 322 without causing the width of the spacing space 324 in the direction perpendicular to the thickness direction Z of the anti-shake motor 123 to increase. The width of the spacing space 324 can still be designed to be small, so that the size of the main circuit board 32 in the thickness direction Z perpendicular to the anti-shake motor 123 is smaller, which helps to miniaturize the design of the anti-shake motor 123.

[0154] There is no limitation on the specific structure of the avoidance gap 325. 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 herein. For example, the depth of the clearance notch 325 in the width direction of the anti-shake motor 123 can be greater than 0.1 mm, and the length of the clearance notch 325 in the longitudinal direction X of the anti-shake 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 that there are solder joints between the IC 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 due to the stress. If the deformation of the coil circuit board 51 is too great, the solder joints between the IC 52 and the coil circuit board 51 may become detached, causing the anti-shake motor 123 to malfunction.

[0156] In order to further improve the firmness of the solder joints between the integrated circuit 52 and the 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 support lug 532. 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 storage 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 storage space and is attached to the coil circuit board 51.

[0157] like Figure 18 As shown, the support lugs 532 are attached to the coil circuit board 51, thereby increasing the strength of the coil circuit board 51, 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. Furthermore, the integrated circuit 52 is located within the shielding body 531, which can also transfer stress near the integrated circuit 52 from the coil circuit board 51 to the support lugs 532, preventing excessive deformation of the portion of the coil circuit board 51 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 portion, two first support plate portions and a second support plate portion. The integrated circuit 52 is located between the first plate portion and the coil circuit board 51 along the thickness direction Z of the anti-shake motor 123. The two first support plate portions are respectively located on opposite sides of the first plate portion. One end of the first support plate portion is fixedly connected to the first plate portion, and the other end of the first support plate portion is fixedly connected to the coil circuit board 51. The second support plate portion and the first support plate portion are located on the same side of the first plate portion and are located between the two first support plate portions. One end of the second support plate portion is fixedly connected to the first plate portion, and the other end of the second support plate portion is fixedly connected to the support ear plate 532.

[0159] In some embodiments, the shielding body 531 may be bonded to the coil circuit board 51, specifically, as shown in FIG. Figure 16 As shown, a first adhesive member 72 is provided between the first support plate and the coil circuit board 51. In addition to connecting the coil circuit boards 51 to each other, the first adhesive member 72 also serves to increase the strength of the coil circuit board 51 and help reduce the degree of deformation of the coil circuit board 51.

[0160] In order to make the ear plate 532 fit closely with the coil circuit board 51, Figure 16 and Figure 18As shown, the anti-shake motor 123 further includes a second adhesive 73. Part of the second adhesive 73 covers the surface of the ear plate 532. Part of the second adhesive 73 covers the surface of the coil circuit board 51. The coil circuit board 51 is fixedly connected to the ear plate 532 via the second adhesive 73. In order to further improve the connection strength of the second adhesive 73, as shown in FIG. Figure 16 As shown, the orthographic projection of the second adhesive member 73 on the coil circuit board 51 is U-shaped, and the second adhesive member 73 covers the edge of the lug plate 532 .

[0161] In order to further protect the solder joints between the integrated circuit 52 and the coil circuit board 51 bracket, in some embodiments, as shown in FIG. Figure 18 As shown, the stator further 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 on the coil circuit board 51 is located within the orthographic projection of the first reinforcing plate 54 on the coil circuit board 51. As can be seen, at least a portion of the first reinforcing plate 54 is located directly below the integrated circuit 52, which can enhance 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 falling off.

[0162] In order to achieve a fixed connection between the first reinforcement 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 reinforcement plate 54 and the coil circuit board 51 and is respectively bonded to the first reinforcement plate 54 and the coil circuit board 51.

[0163] It should be noted that, in addition to the coexistence of the first reinforcing plate 54 and the shielding cover 53 with the lug plates 532, in some scenarios, the first reinforcing plate 54 may be provided alone to protect the solder joints. Alternatively, in some scenarios, the shielding cover 53 with the lug plates 532 may be provided alone to protect the solder joints.

[0164] In some possible implementations, such as Figure 16 As shown, the stator further includes a second reinforcing plate 55. The second reinforcing plate 55 and the first reinforcing plate 54 are located on the same side of the coil circuit board 51. The second reinforcing plate 55 is in contact with the coil circuit board 51, with one end of the second reinforcing plate 55 close to the lug plate 532. This further improves the strength of the coil circuit board 51 and keeps deformation of the coil circuit board 51 within a reasonable range.

[0165] In some embodiments, as Figure 17As shown, the second adhesive 73 partially 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. In addition, one end of the second reinforcing plate 55 can also be welded to the first metal bracket 611 of the coil bracket 61 to fix the second reinforcing plate 55 to the coil circuit board 51.

[0166] When the anti-shake motor 123 is operating, the mover collides with the stator. Specifically, the mover's first magnet bracket 41 and second magnet bracket 42 collide with the stator's housing 62 in the length direction X of the anti-shake motor 123, and the mover's second magnet bracket 42 collides with the stator's coil bracket 61 in the width direction Y of the anti-shake motor 123. As previously described, the second magnet bracket 42 is constructed 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 constructed of metal and plastic, resulting in low strength. Repeated collisions between the connecting plate 422 and the housing 62 can easily cause deformation, resulting in cracking at the weld between the connecting plate 422 and the first magnet bracket 41 and shifting the position of the first magnet 43.

[0167] Figure 20 This is a schematic diagram of another structure of the second magnet bracket and the first magnet bracket provided in an embodiment of the present 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 surface of the connecting plate 422 facing the stator along the length direction X of the anti-shake motor 123 is made of metal, for example Figure 21 As shown, the portion of the connecting plate 422 facing one end surface of the housing 62 along the length direction X of the anti-shake motor 123 (as shown in FIG. Figure 21 In this way, when the connecting plate 422 collides with the stator, the material of the surface where the connecting plate 422 collides with the stator is metal. Figure 4 The surface material of the connecting plate body 422 that collides with the stator is plastic. The strength of metal is higher than that of plastic. Metal is not easily deformed, which can reduce the risk of deformation of the connecting plate body 422 and make the connecting plate body 422 have high deformation resistance.

[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, so that the connecting plate 422 has high strength, reduces the deformation risk of the connecting plate 422, and prevents the connecting plate 422 from deforming.

[0170] like Figure 21 As shown, the connecting plate body 422 is provided with a rib structure 423, however, the connecting plate body 422 may also be provided with a plurality of rib structures 423. Figure 21 As shown, the extending direction of the rib structure 423 is parallel to the thickness direction Z of the anti-shake motor 123 . However, the extending direction of the rib structure 423 may also be perpendicular to or intersect with the thickness direction Z of the anti-shake motor 123 .

[0171] It can be understood that the rib structure 423 is provided on the metal material of the connecting plate body 422 . In this case, the metal material on the connecting plate body 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 portion 411, and the end of the connecting plate 422 away from the bracket body 421 includes a second metal portion 4221. The second metal portion 4221 is welded to the first metal portion 411, thereby fixedly connecting the first magnet bracket 41 and the second magnet bracket 42. Along the length direction X of the anti-shake motor 123, at least part of the orthographic projection of the portion of the second metal portion 4221 that opposes the first metal portion 411 on the first metal portion 411 is located within the first metal portion 411. This increases the weld width between the first and second metal portions 411, and the first metal portion 411 supports the second metal portion 4221, thereby improving the deformation resistance of the connecting plate 422.

[0173] In some embodiments, along the length direction X of the anti-shake 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 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 along the length direction X of the anti-shake motor 123.

[0174] It can be understood that the wider the welding width between the first metal part 411 and the second metal part 4221 in the width direction Y of the anti-shake motor 123, the stronger the connection between the first metal part 411 and the second metal part 4221, and the better the support of the first metal part 411 to the second metal part 4221, so that the second metal part 4221 has better anti-deformation ability, and thus the connecting plate body 422 has better anti-deformation ability.

[0175] In some embodiments, as Figure 21As shown, the first metal portion 411 and the second metal portion 4221 have the same width in the width direction Y of the anti-shake motor 123. In other embodiments, the first metal portion 411 and the second metal portion 4221 may have different widths in the width direction Y of the anti-shake motor 123.

[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 in the width direction Y of the anti-shake motor 123 coincide with each other. 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 arranged, 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 body 422.

[0177] Figure 22 A left side schematic diagram of another embodiment of the present application showing the cooperation between the second magnet bracket and the first magnet bracket.

[0178] In some possible implementations, such as Figure 22 As shown, along the direction from the bracket body 421 to the first magnet bracket 41, the width of the connecting plate 422 in the width direction Y of the anti-shake motor 123 gradually decreases, and both end surfaces of the connecting plate 422 in the width direction Y of the anti-shake motor 123 are inclined surfaces inclined to the thickness direction Z of the anti-shake motor 123 (as shown in FIG. Figure 22 As shown by u1 in FIG. 4 ). 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 where the width direction Y and the thickness direction Z of the anti-shake motor 123 lie.

[0179] During the manufacturing process of the second magnet bracket 42, a draft design is implemented for the connecting plate 422, resulting in inclined surfaces at both ends of the connecting plate 422 in the width direction Y of the anti-shake motor 123. 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 surface where the connecting plate 422 and the coil bracket 61 collide in the width direction Y of the anti-shake motor 123 is made of plastic. By reducing the collision area between the plastic and the coil bracket 61, the generation of fine particles due to the collision is also reduced.

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

[0181] To sum up, the deformation of the connecting plate body 422 can be reduced by exposing the metal material in the connecting plate body 422, setting a rib structure 423, at least partially overlapping the projections of the first metal part 411 and the second metal part 4221, and setting the two end faces of the connecting plate body 422 as inclined surfaces. The more methods adopted, the better the effect on the connecting plate body 422.

[0182] When the anti-shake motor 123 is operating, the movement and stator collide, producing unusual noises that affect the user experience and may be captured by recording equipment during video recording, affecting audio quality. Furthermore, the hard collision between the movement and stator along the longitudinal direction X of the anti-shake motor 123 may generate tiny particles, which in turn may affect the reliability of the anti-shake motor 123 and the imaging quality of the image sensor 122.

[0183] Figure 23 This is a cross-sectional schematic diagram of a first flexible member being provided on opposite sides of a first magnet bracket and a second magnet bracket.

[0184] During the operation of the anti-shake motor 123, the mover and the stator may collide in the length direction X of the anti-shake motor 123. Therefore, in some possible implementations, see Figure 23 As shown, the stator also includes a first flexible member 64, which is provided on opposite sides of the mover along the longitudinal direction X of the anti-shake motor 123. By providing the first flexible member 64 between the mover and the stator, the mover collides with the first flexible member 64 when moving toward the stator along the longitudinal direction X of the anti-shake motor 123. The first flexible member 64 acts as a buffer, reducing or eliminating abnormal impact noise, preventing the appearance of fine particles, and improving image quality.

[0185] There is no limitation on the specific material of the first flexible member 64. For example, the first flexible member 64 can be made of silicone.

[0186] like Figure 23 As shown, the first flexible member 64 is fixedly connected to the inner wall of the housing 62. Of course, the first flexible member 64 can also be fixedly installed on other parts of the stator except the housing 62.

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

[0188] It should be noted that, in addition to being integrated on the stator, the first flexible member 64 can also be integrated on the mover in some scenarios. Integrating the first flexible member 64 on the stator can reduce the weight of the mover and ease the difficulty of moving the mover.

[0189] During the operation of the anti-shake motor 123, the specific parts where the mover and the stator collide in the longitudinal direction X of the anti-shake motor 123 are usually the first magnet bracket 41 and / or the second magnet bracket 42. Therefore, in some possible implementations, along the longitudinal direction X of the anti-shake motor 123, the first flexible member 64 faces at least one of the first magnet bracket 41 and the second magnet bracket 42, for example Figure 23 As shown, the first flexible member 64 faces the first magnet bracket 41 and the second magnet bracket 42. The first flexible member 64 is arranged on opposite sides of the first magnet bracket 41 and / or the second magnet bracket 42, so that the collision between the first magnet bracket 41 and / or the second magnet bracket 42 and the stator is a soft-hard collision, thereby improving or solving the abnormal impact noise and avoiding the generation of tiny particles.

[0190] Figure 24 This is a schematic diagram of the three-dimensional structure of the second flexible member arranged on the coil support. Figure 25 It is a cross-sectional schematic diagram of the cooperation between the second flexible member, the coil bracket, the first magnet bracket and the second magnet bracket.

[0191] During the operation of the anti-shake motor 123, the mover and the stator may collide in the width direction Y of the anti-shake motor 123. Therefore, in some possible implementations, see 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. Second flexible members 65 are provided on opposite sides of the mover along the width direction Y of the anti-shake motor 123. By providing the second flexible member 65 between the mover and the stator, the mover will collide with the second flexible member 65 when moving toward the stator along the width direction Y of the anti-shake motor 123. The second flexible member 65 acts as a buffer, reducing or eliminating abnormal impact noise and preventing the formation of fine particles.

[0192] There is no limitation on the specific material of the second flexible member 65. For example, the second flexible member 65 can be made of 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 integrated 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 on the stator, the second flexible member 65 can also be integrated on the mover in some scenarios. Integrating the second flexible member 65 on the stator can reduce the weight of the mover and ease the difficulty of moving the mover.

[0195] During the operation of the anti-shake motor 123, the specific parts where the mover and the stator collide in the width direction Y of the anti-shake motor 123 are usually 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 bracket 42. By arranging the second flexible member 65 on opposite sides of the first magnet bracket 41 and / or the second magnet bracket 42, the collision between the first magnet bracket 41 and / or the second magnet bracket 42 and the stator is a soft-hard collision, thereby improving or resolving the abnormal impact noise and avoiding the generation of tiny particles.

[0196] For example, 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 smaller than the distance between the coil bracket 61 and the connecting plate 422, and smaller than the distance between the coil bracket 61 and the first magnet bracket 41.

[0197] As previously described, the coil support 61 is composed of a first metal support 611 and a first plastic component 612. While the coil support 61 is lightweight, it also has relatively low overall rigidity. Consequently, during the operation of the anti-shake motor 123, the low-rigidity coil support 61 can cause background noise (i.e., low-frequency noise or vibration). This noise may be caused by the following reasons:

[0198] First, a low-rigidity coil support 61 is more prone to resonance. When the support's natural frequency approaches the external excitation frequency (such as the motor drive frequency), resonance occurs, resulting in a large vibration amplitude. This resonance is transmitted throughout the entire system, causing noticeable background noise. Second, a low-rigidity coil support 61 is prone to deformation or displacement when subjected to force. In the anti-shake motor 123, the coils must move precisely to compensate for hand shake. Insufficient support stiffness can lead to inaccurate coil movement, introducing additional vibration and noise. Third, a low-rigidity coil support 61 can affect system control accuracy. The anti-shake motor 123 typically relies on high-precision position sensors and feedback control systems for fast and accurate adjustment. Insufficient support stiffness can lead to unstable position feedback signals, making it difficult for the control system to accurately control the coil position, thereby increasing background noise. Fourth, a low-rigidity coil support 61 may generate more mechanical losses, such as friction and deformation, during movement. These losses not only reduce system efficiency but also generate additional vibration and noise. 5. In some cases, a low-rigidity coil support 61 may cause the relative position between the coil and the magnet to change, thereby affecting the distribution of the electromagnetic field. This change may cause electromagnetic interference and further increase the background noise.

[0199] In order to reduce the background noise problem caused by the low-rigidity coil support 61, the following measures can be taken to improve it:

[0200] Figure 26 for Figure 3 A first-person perspective diagram of the connection between the coil support and the housing, Figure 27 for Figure 3 Schematic diagram from a second perspective showing the connection between the coil support and the housing.

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

[0202] There is no limitation on the specific welding position between the first metal bracket 611 and the housing 62. Figure 26 As shown, there are three welding positions (such as Figure 26There are three welding positions (as shown in H1, H2 and H3) between the other side of the housing 62 and the first metal bracket 611, which are spaced apart along the length direction of the anti-shake motor 123. Figure 27 (as shown on H4, H5 and H6 in the chart).

[0203] Figure 28 for Figure 7 Schematic diagram of the three-dimensional structure of the first metal bracket.

[0204] In some possible implementations, such as Figure 28 As shown, the first metal bracket 611 is an integrated structure. The integrated first metal bracket 611 is used as a metal skeleton. The first metal bracket 611 has high rigidity and can increase the rigidity of the first plastic part 612, thereby improving the rigidity of the coil bracket 61, thereby achieving the purpose of optimizing the operating noise floor.

[0205] Figure 29 for Figure 3 A first-person perspective diagram of the connection between the coil support and the cover plate, Figure 30 for Figure 3 Schematic diagram from a second perspective 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. Figure 28 As shown, the first metal bracket 611 includes a metal main portion 6111 and a metal bent portion 6112. At least a portion of the metal main portion 6111 is embedded within the first plastic part 612, and the metal bent portion 6112 is fixedly connected to the cover plate 10. By bending the first metal bracket 611 to form the metal bent portion 6112 connected to the second metal bracket 12 of the cover plate 10, the rigidity of the first metal bracket 611 can be increased, thereby increasing the rigidity of the first plastic part 612. As a result, the coil bracket 61 has high rigidity, which can effectively reduce the noise floor problem caused by the low rigidity of the coil bracket 61.

[0207] Combine Figure 29 and Figure 30 It can be seen that metal bending portions 6112 are provided on opposite sides of the metal main body 6111 , so that the opposite sides of the first metal bracket 611 are respectively welded to the opposite sides of the second metal bracket 23 .

[0208] Typically, during the assembly process of the anti-shake motor 123, tiny particles may be present inside the motor 123, causing a particle problem. This can affect the operation of the motor and / or the photosensitivity of the image sensor 122, resulting in poor image quality. The "particle problem" generally refers to the impact of tiny particles on motor performance. The particle problem can be improved by the following measures:

[0209] Figure 31 for Figure 3 Schematic diagram of the three-dimensional structure of the shell.

[0210] In some possible implementations, such as Figure 31 As shown, the housing 62 serves as part of the cavity wall of the housing and has a water wash hole 63 that communicates with the interior of the housing. This allows 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 and directly remove particles attached to the mover, stator, and suspension wire 322. Therefore, a properly designed water wash hole 63 can effectively resolve the particle problem within the anti-shake motor 123 and improve the overall performance and reliability of the anti-shake motor 123.

[0211] It is understandable that after cleaning is completed, the cleaning medium is removed through the water washing hole 63 to ensure internal drying. In addition, after removing the cleaning medium, the water washing hole 63 needs to be blocked, for example, using a sealant to seal the water washing hole 63.

[0212] There is no limitation on the specific shape of the water washing hole 63. For example, the water washing hole 63 can be a circular hole.

[0213] In some embodiments, as shown, the water washing hole 63 is located on one side of the housing 62 along the length direction X of the anti-shake motor 123. In other embodiments, the water washing hole 63 may also be located on one side of the housing 62 along the width direction Y of the anti-shake motor 123. In still other embodiments, the water washing hole 63 may also be located on the portion of the housing 62 opposite the first magnet bracket 41 along the thickness direction Z of the anti-shake motor 123.

[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 outer shell 62 away from the suspension wire 322 is less than or equal to one third of the thickness of the anti-shake motor 123, which can reduce the difficulty of discharging the cleaning medium used in the water washing process from the inside of the anti-shake motor 123 and improve the water washing effect.

[0215] In some possible implementations, the anti-shake motor 123 further includes a colloid member (not shown). This colloid member can be positioned at the location where the mover and stator collide. Of course, the colloid member is not limited to this location. Because the colloid member is a low-viscosity glue with poor fluidity, it can remain in one location for extended periods of time. This colloid member can absorb small particles into the interior, preventing them from flowing within the anti-shake motor 123.

[0216] The specific type of the colloid member is not limited here. For example, the colloid member can be dust collecting glue.

[0217] In some embodiments, a colloid is provided on the surface of at least one of the coil support 61 , the cover plate 10 and the coil circuit board assembly 50 . For example, a colloid is provided on the surfaces of the coil support 61 , the cover plate 10 and the coil circuit board assembly 50 .

[0218] There are no specific restrictions on where the colloid member is placed on the coil holder 61. For example, the colloid member may be placed at the location where the coil holder 61 collides with the holder body 421 of the second magnet holder 42 in the thickness direction Z perpendicular to the anti-shake motor 123. Specifically, the colloid member may be placed on the surface of the coil holder 61 where the colloid member collides with the second magnet holder 42 along the length direction X and width direction Y of the anti-shake motor 123.

[0219] There is no limitation on the specific location of the colloid member on the cover 10. For example, the colloid member can be provided on the surface of the cover 10 opposite to the second magnet bracket 42 along a direction perpendicular to the thickness direction Z of the anti-shake motor 123.

[0220] There is no limitation on the location of the colloid member on the coil circuit board assembly 50. For example, the colloid member may be disposed on the surface of the shielding cover 53, the surface of the second reinforcing plate 55, or the like.

[0221] To improve the control performance of the anti-shake motor 123, in some possible implementations, the anti-shake 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 anti-shake motor 123 includes the first damping element 66, the second damping element 67, and the 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 member and the first magnet bracket in cooperation.

[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 first magnet bracket 41 and the bracket body 421 of 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 members 66, wherein the two ends of one first damping member 66 are in contact with the first magnet bracket 41 and the second reinforcement plate 55 of the coil circuit board assembly 50 respectively, and the two ends of the other first damping member 66 are in contact with the first magnet bracket 41 and the coil bracket 61 respectively.

[0224] It should be noted that, in addition to the second reinforcing plate 55 , the specific parts of the coil circuit board assembly 50 that come into contact with the first damping member 66 may also include the shielding cover 53 , the first coil 56 , the second coil 57 , the coil circuit board 51 and other parts.

[0225] The first damping member 66 is made of a damping material, for example, a damping rubber (also known as a shock-absorbing rubber or buffer material) such as silicone rubber, polyurethane, or thermoplastic elastomer. The first damping member 66 can help reduce unnecessary vibration, impact, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing the control performance of the anti-shake motor 123.

[0226] The specific structure of the first damping member 66 is not limited here. Figure 16 As shown, the first damping member 66 may be cylindrical.

[0227] Figure 33 Schematic diagram of the pavement in which the second damping member cooperates with the housing and the first magnet bracket.

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

[0229] The second damping member 67 is made of a damping material, such as a damping rubber (also known as a shock-absorbing rubber or buffer material) such as silicone rubber, polyurethane, or thermoplastic elastomer. The second damping member 67 can help reduce unnecessary vibration, impact, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing the control performance of the anti-shake motor 123.

[0230] There is no limitation on the specific structure of the second damping member 67. For example, the second damping member 67 may 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) for accommodating part of the second damping member 67 along the thickness direction Z of the anti-shake motor 123 toward the side of the outer shell 62, which can locate the position of the second damping member 67 and increase the size of the second damping member 67 in the thickness direction Z of the anti-shake motor 123.

[0232] Figure 34 is a cross-sectional diagram of the cooperation between the third damping member, the coil bracket and the second magnet bracket. 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 member 68 is located between the second magnet bracket 42 and the coil bracket 61 , and both ends of the third damping member 68 are in contact with the coil bracket 61 and the second magnet bracket 42 respectively.

[0234] The third damping member 68 is made of a damping material, for example, a damping rubber (also known as a shock-absorbing rubber or buffer material) such as silicone rubber, polyurethane, or thermoplastic elastomer. The third damping member 68 can help reduce unnecessary vibration, impact, and the resulting noise, while also improving the stability and response speed of the anti-shake motor 123 and enhancing the control performance of the anti-shake motor 123.

[0235] There is no limitation on the specific structure of the third damping member 68. For example, the third damping member 68 may 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) for accommodating part of the third damping member 68 along the thickness direction Z of the anti-shake motor 123 on one side toward the coil bracket 61, which can locate the position of 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 conductive sheet 412 and a second magnetic conductive sheet 413. The first magnetic conductive sheet 412 is located between the first magnet part 43 and the second magnetic conductive sheet 413. The first magnet part 43 is a Halbach magnet array. The Halbach magnet array combined with the design of dual magnetic conductive sheets 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 smaller, reducing rebound or vibration and improving control accuracy. Low restoring force helps the anti-shake motor 123 reach the target position and stabilize faster, which is especially important for the anti-shake motor 123 that requires a fast response.

[0238] In some possible implementations, such as Figure 23 As shown, the stator also includes a third magnet 45. This third magnet 45 is located on the side of the second magnetic conductive sheet 413 away from the first magnetic conductive sheet 412, along the thickness direction Z of the anti-shake motor 123. The third magnet 45 is spaced apart from the second magnetic conductive sheet 413. The third magnet 45 is magnetically connected to the second magnetic conductive sheet 413, creating a magnetic attraction between them. Furthermore, because the position of the third magnet 45 remains unchanged, the magnetic attraction holds the first magnet support 41 in place, preventing it from accidentally moving toward the image sensor 122. Furthermore, the Halbach magnet array combined with the dual magnetic conductive sheets creates a strong magnetic attraction structure that is insensitive to the distance between the third magnet 45 and the second magnetic conductive sheet 413 in the thickness direction Z of the anti-shake motor 123, facilitating assembly and commissioning. Therefore, there is no need for a separate magnetic conductive sheet to mate with the third magnet 45.

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

[0240] For example, Figure 23 As shown, the third magnetic component 45 can be fixed on the inner wall of the shell 62 , for example, the third magnetic component 45 is bonded to the inner wall of the shell 62 .
