Technical Field

[0002] The present application relates to the field of camera technology, and in particular to an anti-shake motor, an image sensor assembly, a camera module and an electronic device. Background Art

[0003] With the popularity and development of smartphones, mobile photography has become a common photography method, and phones with optical image stabilization are increasingly popular. Traditional camera modules consist of an image sensor anti-shake motor and an image sensor. The image sensor anti-shake motor achieves image stabilization by controlling the movement of the image sensor. Traditional image sensor anti-shake motors generally achieve driving force through the combination of coils and magnets. However, because the magnetic flux lines of traditional magnets are only effectively utilized on one side by the drive coil, the Z-direction magnetic field utilization is low, resulting in a small drive stroke for traditional image sensor anti-shake motors. Summary of the Invention

[0004] The embodiments of the present application provide an anti-shake motor, an image sensor assembly, a camera module, and an electronic device, aiming to obtain an anti-shake motor that can improve the utilization rate of magnetic flux lines and achieve a larger rated stroke.

[0005] In a first aspect, an anti-shake motor is provided. The anti-shake motor includes a fixed carrier, a movable carrier, a driving magnetic component, a first driving coil, and a second driving coil. The movable carrier is used to fix the image sensor module.

[0006] The driving magnetic member is fixed to the fixed carrier, the first driving coil and the second driving coil are both fixed to the movable carrier, and the driving magnetic member is located between the first driving coil and the second driving coil;

[0007] The first driving coil and the second driving coil both face the driving magnetic component to drive the movable carrier to move relative to the fixed carrier.

[0008] It is understandable that the present application provides a driving architecture of a magnetic coil similar to a "sandwich". The driving magnetic part is fixed to a fixed carrier, the first driving coil and the second driving coil are both fixed to a movable carrier, and the driving magnetic part is located between the first driving coil and the second driving coil. It is understandable that, on the one hand, the magnetic flux lines on both sides of the driving magnetic part can be fully utilized by the first driving coil and the second driving coil. The magnetic field utilization rate of the driving magnetic part is high, which is conducive to improving the driving stroke of the anti-shake motor. On the other hand, compared with the solution in which the first driving coil and the second driving coil are laid flat on the XY plane, the first driving coil, the driving magnetic part and the second driving coil of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the dimensions in the XY-axis direction. This can greatly improve the space utilization in the Z-axis direction, and improve the utilization rate of the magnetic flux lines to achieve an increase in thrust, making it possible to apply anti-shake to telephoto modules with more compact space and larger rated stroke requirements.

[0009] In addition, since the first driving magnetic component and the second driving magnetic component can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component and the second driving magnetic component will not affect each other, which is conducive to maximizing the number of the first driving magnetic component and the second driving magnetic component.

[0010] In one possible implementation, the fixed carrier includes a magnetic isolation sheet, the magnetic isolation sheet includes a first surface and a second surface disposed opposite to each other, the first surface facing the first drive coil, and the second surface facing the second drive coil; the drive magnetic member includes a first drive magnetic member and a second drive magnetic member, the first drive magnetic member is fixed to the first surface, and the second drive magnetic member is fixed to the second surface;

[0011] The first driving coil faces the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction;

[0012] The second driving coil includes a first sub-driving coil, and the first sub-driving coil faces the second driving magnetic member to drive the movable carrier to move relative to the fixed carrier along a second direction, which is different from the first direction.

[0013] It can be understood that the first drive coil faces the first drive magnetic part to drive the movable carrier to move relative to the fixed carrier along the first direction X. The first sub-drive coil of the second drive magnetic part faces the second drive magnetic part to drive the movable carrier to move relative to the fixed carrier along the second direction Y. In this way, the movable carrier can move relative to the fixed carrier along a plane perpendicular to the third direction Z (that is, the XY plane). When the camera module collects ambient light, if the electronic device vibrates in the XY plane due to external force, the movement of the image sensor module on the XY plane can be controlled to offset the jitter stroke of the camera module in the XY plane, so as to avoid or reduce the position bias of the camera module caused by the jitter, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0014] Furthermore, the first drive magnetic component is fixed to the first surface of the magnetic isolation plate, and the second drive magnetic component is fixed to the second surface of the magnetic isolation plate. This allows the magnetic isolation plate to effectively isolate the first and second drive magnetic components from crosstalk, ensuring efficient utilization of their magnetic flux lines.

[0015] In addition, since the first driving magnetic component and the second driving magnetic component can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component and the second driving magnetic component will not affect each other, which is conducive to maximizing the number of the first driving magnetic component and the second driving magnetic component.

[0016] In a possible implementation, the second drive coil includes a second sub-drive coil, which is spaced apart from the first sub-drive coil; the second sub-drive coil faces the second drive magnetic component to drive the movable carrier to rotate relative to the fixed carrier.

[0017] It can be understood that by setting the second sub-drive coil to face the second drive magnetic part to drive the movable carrier to rotate relative to the fixed carrier, rotation compensation can be performed. For example, when the movable carrier is driven to rotate clockwise relative to the fixed carrier, the movable carrier will drive the image sensor module to rotate clockwise. At this time, by controlling the direction and magnitude of the current on the second sub-drive coil of the second drive coil, a compensating driving force for the movable carrier to rotate counterclockwise relative to the fixed carrier is obtained, thereby achieving rotation compensation of the movable carrier around the Z-axis direction. At this time, the image sensor module also performs rotation compensation around the Z-axis direction to offset the jitter stroke generated by the rotation of the camera module around the Z-axis direction, thereby avoiding or reducing the position offset of the camera module caused by jitter, thereby achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0018] In one possible implementation, there are two second sub-drive coils, which are connected in series, and the currents flowing through the two second sub-drive coils are directed in opposite directions. Thus, when the two second sub-drive coils are energized, the forces acting on the two second sub-drive coils are opposite. For example, when the first second sub-drive coil is subjected to a force in the positive direction of the Y-axis, the second second sub-drive coil is subjected to a force in the negative direction of the Y-axis. At this point, the torque exerted by the two second sub-drive coils on the movable carrier causes the movable carrier to rotate relative to the fixed carrier.

[0019] In a possible implementation, the anti-shake motor includes a first position sensor, a second position sensor, and a third position sensor, wherein the first position sensor, the second position sensor, and the third position sensor are all fixed to the movable carrier at intervals;

[0020] The first position sensor and the second position sensor are used to independently detect the displacement of the movable carrier relative to the fixed carrier along the first direction, and are also used to cooperate with each other to detect the rotation angle of the movable carrier relative to the fixed carrier;

[0021] And / or, the anti-shake motor includes a third position sensor, the third position sensor is fixed to the movable carrier, and the third position sensor is used to detect the displacement of the movable carrier relative to the fixed carrier along the second direction.

[0022] In one possible implementation, the movable carrier is movably connected to the fixed carrier via a rolling element. It is understood that compared to the solution in which the movable carrier is movably connected to the fixed carrier via a guide bracket, this embodiment has a simpler connection method and a more simplified structure, which is conducive to miniaturizing the anti-shake motor.

[0023] Exemplarily, there are three rolling elements, which are distributed at different positions, and the carrier is fixed with three-point support to achieve a stable setting of the anti-shake motor.

[0024] In a possible implementation, the fixed carrier includes a metal part and an insulating part. The metal part is embedded in the insulating part. The metal part includes an extension portion that is exposed relative to the insulating part. The rolling part is provided on the movable carrier and contacts the extension portion.

[0025] It can be understood that, since the extension portion of the fixed carrier is made of metal material, the friction between the rolling element and the fixed carrier is relatively small, which is conducive to improving the stable movement of the movable carrier relative to the fixed carrier.

[0026] In a possible implementation, the movable carrier is provided with a rolling element groove. The rolling element is located in the rolling element groove. In this way, the rolling element is not easily dislodged from the movable carrier.

[0027] In one possible implementation, grease is provided between the rolling element and the rolling element groove. This further reduces friction between the rolling element and the fixed support, thereby better achieving a super-slip rolling element system. Furthermore, the rolling element is less likely to fall out of the rolling element groove.

[0028] In a possible implementation, the extension portion is made of magnetic material, the movable carrier is provided with a magnetic component, and the magnetic component is arranged opposite to the extension portion.

[0029] It is understood that the magnetic member is disposed relative to the extension. A magnetic attraction force can be generated between the magnetic member and the extension. This magnetic attraction force can cause the movable carrier to tend to approach the fixed carrier. In this way, the movable carrier can stably attract the fixed carrier in the Z-axis direction, improving the stability of the movable carrier when it moves relative to the fixed carrier.

[0030] It is understandable that the extension of the fixed carrier can provide a smooth contact surface for the rolling element and also serve as a magnetic attraction element for the magnetic element. The extension of the fixed carrier has a "one-item-multiple-purposes" function.

[0031] It is understood that by arranging both the rolling element and the magnetic element on the movable carrier, the relative positions of the rolling element and the magnetic element are less likely to change significantly when the movable carrier moves relative to the fixed carrier. In particular, when there are multiple rolling elements and multiple magnetic elements, the relative positions of the contact centers of the multiple rolling elements with the fixed carrier and the centers of magnetic attraction of the multiple magnetic elements are less likely to change. In this case, the movable carrier has better stability when moving relative to the fixed carrier, thus achieving stable contact and smooth movement between the movable and fixed carriers.

[0032] In one possible implementation, the movable carrier includes a first bracket and a second bracket; the first bracket includes a base plate, a first protrusion, and a second protrusion, the first protrusion and the second protrusion being protrudingly disposed on the same side of the base plate; the second bracket is fixedly connected to the first protrusion and the second protrusion, and is disposed opposite to and spaced from the base plate;

[0033] The first driving coil is fixed to the bottom plate, and the second driving coil is fixed to the second bracket.

[0034] It is understandable that by configuring the movable carrier to consist of a first bracket and a second bracket, when the second bracket is mounted on the first and second protrusions of the first bracket, the second bracket and the base plate are opposite and spaced apart, that is, there is an installation space between the second bracket and the base plate. At this time, a portion of the fixed carrier is then arranged between the base plate of the first bracket and the second bracket. In this way, when the driving magnetic member is fixed to the fixed carrier and the first and second driving coils are both fixed to the movable carrier, the driving magnetic member can be located between the first and second driving coils.

[0035] It can be understood that by configuring the movable carrier to consist of a first bracket and a second bracket, it is helpful to facilitate the assembly of the movable carrier and the fixed carrier.

[0036] In one possible implementation, the anti-shake motor also includes a movable circuit board, which includes a first fixed part, an elastic part and a second fixed part, and the elastic part is connected between the first fixed part and the second fixed part; the base plate of the first bracket is fixed to the first fixed part, and the fixed carrier is fixed to the second fixed part; the image sensor module is fixed to the side of the first fixed part away from the movable carrier.

[0037] It can be understood that when the movable carrier moves along the first direction X, the elastic portion of the movable circuit board is deformed along the first direction X. The image sensor module and the first fixed portion of the movable circuit board can follow the movable carrier to move along the first direction X. When the movable carrier moves along the second direction Y relative to the fixed carrier, the elastic portion of the movable circuit board is deformed along the second direction Y. The image sensor module and the first fixed portion of the movable circuit board can follow the movable carrier to move along the second direction Y. Therefore, the movable carrier can control the image sensor module to move along a plane perpendicular to the third direction Z (i.e., the XY plane) through the movable circuit board. When the camera module collects ambient light, if the electronic device shakes in the XY plane due to external force, the movement of the image sensor module on the XY plane can be controlled to offset the shaking stroke of the camera module in the XY plane, so as to avoid or reduce the position offset of the camera module caused by shaking, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0038] Furthermore, when the movable carrier is driven to rotate clockwise relative to the fixed carrier, the movable carrier drives the image sensor module to rotate clockwise via the elastic portion of the movable circuit board. In this embodiment, by controlling the direction and magnitude of the current in the second sub-drive coil of the second drive coil to obtain a compensating driving force for counterclockwise rotation of the movable carrier relative to the fixed carrier, rotation compensation of the movable carrier about the Z-axis is achieved. At this time, the image sensor module also rotates about the Z-axis to compensate for the jitter caused by the camera module's rotation about the Z-axis, thereby avoiding or reducing positional offset of the camera module caused by jitter, thereby achieving optical image stabilization of the camera module and improving the camera module's imaging quality.

[0039] Exemplarily, the image sensor module is further electrically connected to the first fixing portion of the movable circuit board. The image sensor can be electrically connected to the first fixing portion of the movable circuit board via the module circuit board, and electrically connected to the exterior of the image sensor assembly via the elastic portion and the second fixing portion of the movable circuit board.

[0040] In one possible implementation, the elastic portion is spiral, zigzag, or curved. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion. The movement stroke of the movable circuit board is less restricted, which is conducive to realizing the setting of a movable carrier with a larger anti-shake stroke. In addition, the spiral-shaped low-K value elastic portion can effectively compress the dimensions in the X and Y axes while maintaining a small size in the Z-axis direction, reduce crosstalk in the XY plane movement, and optimize the electromagnetic drive performance and power consumption performance.

[0041] In a possible implementation, the length of the elastic portion is greater than half the circumference of the edge of the first fixing portion. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion.

[0042] In one possible implementation, the elastic portion surrounds at least half of the edge of the first fixing portion, or the elastic portion surrounds the edge of the first fixing portion in multiple turns. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion.

[0043] In a possible implementation, the elastic coefficient of the movable circuit board in the length direction is K Y , K Y The size is in the range of 25 to 35; and / or, the elastic coefficient of the movable circuit board in the width direction is K X , K X The size of is in the range of 85 to 100. At this time, the K of the active circuit board Y Less than K X .

[0044] It is understandable that due to the K Y Less than K X , so that the travel of the movable carrier relative to the fixed carrier in the second direction Y is limited to a travel of the movable carrier relative to the fixed carrier in the first direction X. In this case, the embodiment can better match the K of the movable circuit board by setting the driving force generated by the first sub-driving coil and the second driving magnetic member to be smaller than the driving force generated by the first driving coil and the first driving magnetic member. Y Less than K X For example, the number of the first sub-driving coils and the number of the second driving magnetic members can be set to be smaller, thereby facilitating a miniaturized setting of the anti-shake motor.

[0045] In one possible implementation, the movable circuit board further includes a reinforcement portion located on the first fixing portion, and the movable carrier is fixed to the reinforcement portion. It is understood that the reinforcement portion may be a steel plate or other metal plate. The reinforcement portion can enhance the overall strength of the first fixing portion.

[0046] In one possible implementation, the first bracket also includes a fixing protrusion, which is protruded from the base plate and is located on a side of the base plate away from the first protrusion and / or the second protrusion; the fixing protrusion passes through the gap of the elastic part and is fixedly connected to the image sensor module.

[0047] It is understood that by providing a fixed protrusion on the bottom plate of the first bracket, and using the fixed protrusion to pass through the movable circuit board, it is directly fixedly connected to the image sensor module. Thus, compared to the scheme in which the image sensor module is fixedly connected to the first bracket via the movable circuit board, in this embodiment, on the one hand, the assembly tolerance chain between the image sensor module and the first bracket is shorter, the assembly tolerance between the image sensor module and the first bracket is smaller, and the image sensor module and the bottom plate of the first bracket can be largely in the same plane. On the other hand, when the movable carrier moves in the XY plane, the movable carrier can directly drive the movement of the image sensor module, and the movement of the image sensor module is less affected by the movable circuit board.

[0048] In one possible implementation, the anti-shake motor includes a first circuit board and an anti-shake drive chip; the first circuit board is fixed to the bottom plate of the first bracket; the first drive coil and the anti-shake drive chip are both fixed to the first circuit board, and the input and output ends of the first drive coil form a current loop through the first circuit board and the anti-shake drive chip.

[0049] In one possible implementation, the bottom plate of the first bracket is provided with a first avoidance hole, the first circuit board is provided with a second avoidance hole, and the first avoidance hole is arranged opposite to the second avoidance hole; the movable circuit board includes an electrical connection part, the electrical connection part is fixed to the first fixing part, a part of the electrical connection part passes through the first avoidance hole and is located in the second avoidance hole, and the pin end of the electrical connection part is electrically connected to the second pin end of the first circuit board; the anti-shake drive chip is electrically connected to the electrical connection part through the first circuit board, and is electrically connected to the outside through the first fixing part, the elastic part and the second fixing part of the movable circuit board.

[0050] It can be understood that compared with the traditional main camera anti-shake solution, the image sensor module, movable circuit board, first circuit board, and anti-shake driver chip of this implementation method are separated in the Z-axis direction, and an electrical connection part is set on the movable circuit board to achieve electrical connection between the image sensor and the anti-shake driver chip, effectively utilizing the Z-axis space and further improving the utilization rate of the XY plane space.

[0051] In one possible implementation, the anti-shake motor includes a second circuit board secured to a second bracket, and a second drive coil secured to the second circuit board. The second drive coil forms a current loop with the anti-shake drive chip via the second circuit board, conductive elements within the movable carrier, and the first circuit board. This simplifies the electrical connection between the second drive coil and the anti-shake drive chip.

[0052] In a possible implementation, the fixed carrier includes a top plate, a first side plate and a second side plate that are oppositely disposed, and the top plate is connected between the first side plate and the second side plate;

[0053] The top plate is arranged at an obtuse angle to the first side plate, and / or the top plate is arranged at an obtuse angle to the second side plate;

[0054] At least part of the top plate forms a magnetic isolation plate, the first surface of the magnetic isolation plate is the surface of the top plate facing the inner side of the fixed carrier, and the second surface of the magnetic isolation plate is the surface of the top plate facing away from the outer side of the fixed carrier.

[0055] It can be understood that by setting the top plate and the first side plate at an obtuse angle, and / or the top plate and the second side plate at an obtuse angle, the fixed carrier is roughly in the shape of a "pyramid". At this time, the second drive coil is arranged on one side of the top plate of the fixed carrier, the first drive magnetic part and the second drive magnetic part are arranged on the top plate of the fixed carrier, and the second drive coil is located on the bottom side of the fixed carrier. In this way, in this implementation, the anti-shake motor has a "pyramid" stacked structure, the second drive coil is arranged at the top layer, the first drive magnetic part and the second drive magnetic part are arranged from top to bottom in the middle layer, and the first drive coil is arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupling image sensor.

[0056] In a possible implementation, the anti-shake motor further includes a guide bracket, and the guide bracket includes a first supporting portion, a second supporting portion, and a third supporting portion;

[0057] The first support portion, the second support portion and the third support portion are connected to the first bracket of the movable carrier through multiple first support members, and are connected to the fixed carrier through multiple second support members, so that the relative movement direction of the movable carrier and the guide bracket is different from the relative movement direction of the guide bracket and the fixed carrier.

[0058] It is understandable that the movable carrier is movably connected to the fixed carrier via the guide bracket, and the movable carrier is less likely to rotate relative to the fixed carrier. The movement of the movable carrier is more stable.

[0059] In one possible implementation,

[0060] The driving magnetic member includes a first driving magnetic member and a second driving magnetic member; the first driving coil includes a first sub-driving coil and a second sub-driving coil; the second driving coil includes a first sub-driving coil and a second sub-driving coil; the first driving magnetic member is located between the first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil, and the second driving magnetic member is located between the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil;

[0061] The first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil both face the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction;

[0062] The second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil both face the second driving magnetic component to drive the movable carrier to move relative to the fixed carrier along a second direction different from the first direction.

[0063] It can be understood that by positioning the first drive magnetic member between the first sub-drive coil of the first drive coil and the first sub-drive coil of the second drive coil, the magnetic flux lines on both sides of the first drive magnetic member can be fully utilized by the first sub-drive coil of the first drive coil and the first sub-drive coil of the second drive coil. This high magnetic field utilization rate of the first drive magnetic member helps to increase the drive stroke of the anti-shake motor.

[0064] It can be understood that by positioning the second drive magnetic member between the second sub-drive coil of the first drive coil and the second sub-drive coil of the second drive coil, the magnetic flux lines on both sides of the second drive magnetic member can be fully utilized by the second sub-drive coil of the first drive coil and the second sub-drive coil of the second drive coil. This higher magnetic field utilization rate of the second drive magnetic member helps to increase the drive stroke of the anti-shake motor.

[0065] In a possible implementation, the fixed carrier is provided with a first through hole and a second through hole, the first driving magnetic component is located in the first through hole, and the second driving magnetic component is located in the second through hole.

[0066] In one possible implementation, the driving magnetic member includes a third driving magnetic member; the first driving coil includes a third sub-driving coil, the second driving coil includes a third sub-driving coil, and the third driving magnetic member is located between the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil; the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil face the third driving magnetic member to drive the movable carrier to rotate relative to the fixed carrier.

[0067] It can be understood that by positioning the third drive magnetic member between the third sub-drive coil of the first drive coil and the third sub-drive coil of the second drive coil, the magnetic flux lines on both sides of the third drive magnetic member can be fully utilized by both the third sub-drive coil of the first drive coil and the third sub-drive coil of the second drive coil. This higher magnetic field utilization rate of the third drive magnetic member helps increase the drive stroke of the anti-shake motor.

[0068] In a possible implementation, the fixed carrier is provided with a third through hole, and the third driving magnetic component is located in the third through hole.

[0069] In a second aspect, an anti-shake motor is provided. The anti-shake motor includes a fixed carrier, a movable carrier, a drive coil, a first drive magnetic member, and a second drive magnetic member. The movable carrier is used to fix the image sensor module. The drive coil is fixed to the fixed carrier. The first drive magnetic member and the second drive magnetic member are both fixed to the movable carrier. The drive coil is located between the first drive magnetic member and the second drive magnetic member.

[0070] The driving coil faces the first driving magnetic component and the second driving magnetic component to drive the movable carrier to move relative to the fixed carrier.

[0071] It can be understood that this embodiment provides a driving structure of a "sandwich"-like magnetic coil. Specifically, the driving coil is fixed to a fixed carrier, the first driving magnetic part and the second driving magnetic part are both fixed to a movable carrier, and the driving coil is located between the first driving magnetic part and the second driving magnetic part. Compared with the solution in which the first driving magnetic part and the second driving magnetic part are laid flat on the XY plane, the first driving magnetic part, the driving coil and the second driving magnetic part of the present application are arranged in sequence in the Z-axis direction, which effectively utilizes the space in the Z-axis direction, compresses the dimensions in the XY-axis direction, and can greatly improve the space utilization in the Z-axis direction.

[0072] In addition, since the first driving magnetic component and the second driving magnetic component can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component and the second driving magnetic component will not affect each other, which is conducive to maximizing the number of the first driving magnetic component and the second driving magnetic component.

[0073] It is understood that because the drive coil is fixed to the fixed carrier, and the first and second drive magnetic members are both fixed to the movable carrier, the anti-shake motor of this embodiment is a moving magnet motor. As such, the electrical connection method for the drive coil of this embodiment is simpler than that of a moving coil motor.

[0074] It can be understood that since the drive coil is located between the first drive magnetic component and the second drive magnetic component, the first drive magnetic component and the second drive magnetic component are far apart, which is beneficial to reducing the crosstalk of the magnetic flux lines of the first drive magnetic component and the second drive magnetic component, and ensuring the utilization rate of the magnetic flux lines of the first drive magnetic component and the second drive magnetic component.

[0075] In one possible implementation, the drive coil includes a first drive coil and a second drive coil, and the second drive magnetic part includes a first sub-drive magnetic part; the first drive coil faces the first drive magnetic part to drive the movable carrier to move relative to the fixed carrier along a first direction; the second drive coil faces the first sub-drive magnetic part to drive the movable carrier to move relative to the fixed carrier along a second direction, and the second direction is different from the first direction.

[0076] It can be understood that the first drive coil faces the first drive magnetic part to drive the movable carrier to move relative to the fixed carrier along the first direction X. The second drive coil faces the first sub-drive magnetic part to drive the movable carrier to move relative to the fixed carrier along the second direction Y. In this way, the movable carrier can move relative to the fixed carrier along a plane perpendicular to the third direction Z (that is, the XY plane). When the camera module collects ambient light, if the electronic device vibrates in the XY plane due to external force, the movement of the image sensor module in the XY plane can be controlled to offset the jitter stroke of the camera module in the XY plane, so as to avoid or reduce the position bias of the camera module caused by the jitter, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0077] In a possible implementation, the first drive coil and the second drive coil are arranged along a third direction, and the third direction is different from both the first direction and the second direction.

[0078] Compared with the solution in which the first drive coil and the second drive coil are laid out in the XY plane, the first drive coil and the second drive coil of the present application are arranged along the third direction, which can further utilize the space in the Z-axis direction, further compress the dimensions in the XY-axis direction, and greatly improve the space utilization in the Z-axis direction.

[0079] In one possible implementation, the anti-shake motor includes a motor circuit board, which is fixed to a fixed carrier; the motor circuit board includes a first surface and a second surface arranged along a third direction, the first drive coil is fixed to the first surface of the motor circuit board, and the second drive coil is fixed to the second surface of the motor circuit board.

[0080] In one possible implementation, the fixed carrier has a mounting hole that communicates with an inner space of the fixed carrier; at least a portion of the first drive coil is located within the mounting hole. This allows the fixed carrier to no longer separate the first drive coil from the first drive magnetic component, allowing the first drive coil to be positioned as close to the first drive magnetic component as possible. Furthermore, the first drive coil and the fixed carrier overlap in the Z-axis direction, thereby reducing their dimensions in the Z-axis direction.

[0081] In a possible implementation, the driving coil includes a third driving coil, and the third driving coil faces the first sub-driving magnetic component to drive the movable carrier to rotate relative to the fixed carrier.

[0082] It is understood that by providing the third drive coil and the first sub-drive magnetic component, rotation compensation about the Z-axis can be achieved. For example, when the movable carrier rotates clockwise relative to the fixed carrier, the direction and magnitude of the current in the second sub-drive coil of the second drive coil can be controlled to obtain a compensating driving force that causes the movable carrier to rotate counterclockwise relative to the fixed carrier, thereby achieving rotation compensation of the movable carrier about the Z-axis. In addition, because the third drive coil and the second drive coil can share the same first sub-drive magnetic component, the structure of the anti-shake motor is simplified, which is conducive to the miniaturization of the anti-shake motor.

[0083] It is understandable that the third drive coil and the second drive coil can share the first sub-drive magnetic component. Therefore, the structure of the anti-shake motor of this embodiment is relatively simple.

[0084] In one possible implementation, there are multiple third drive coils; the multiple third drive coils are located on both sides of the second drive coil in the length direction, or the multiple third drive coils are located on the same side of the second drive coil in the width direction. In this way, the arrangement between the third drive coils and the second drive coils is more compact.

[0085] In a possible implementation, the drive coil includes a fourth drive coil, and the fourth drive coil is arranged in the same layer as the second drive coil;

[0086] The second driving magnetic component includes a second sub-driving magnetic component, which is arranged on the same layer as the first sub-driving magnetic component; the fourth driving coil faces the second sub-driving magnetic component to drive the movable carrier to move relative to the fixed carrier along the first direction.

[0087] It is understandable that by additionally disposing a fourth drive coil in the same layer as the second drive coil, and additionally disposing a second sub-drive magnetic component in the same layer as the first sub-drive magnetic component, and utilizing the fourth drive coil and the second sub-drive magnetic component, the movable carrier is driven to move relative to the fixed carrier in the first direction X. In this case, the fourth drive coil and the second sub-drive magnetic component can cooperate with the first drive coil and the first drive magnetic component to significantly increase the driving force for the movable carrier to move relative to the fixed carrier in the first direction X, thereby facilitating an increase in the travel of the movable carrier relative to the fixed carrier in the first direction X.

[0088] In a possible implementation, the movable carrier includes a first bracket and a second bracket;

[0089] The first bracket includes a base plate, a first protrusion and a second protrusion, the first protrusion and the second protrusion are protruded on the same side of the base plate, the second bracket is fixedly connected to the first protrusion and the second protrusion, and is opposite to and spaced apart from the base plate, and at least part of the fixed carrier is located between the base plate and the second bracket; the first driving magnetic component is fixed to the base plate, and the second driving magnetic component is fixed to the second bracket.

[0090] It is understood that since the movable carrier can be formed by assembling the first bracket and the second bracket, when assembling the movable carrier with other structural components, the first bracket and the second bracket can be assembled with the other structural components first, and then the second bracket can be fixed to the first bracket. This assembly method can reduce the assembly of other structural components and the movable carrier.

[0091] In a possible implementation, the movable carrier is movably connected to the fixed carrier via a connecting member.

[0092] In a possible implementation, there are three connecting members, which are distributed at different positions, and the carrier is fixed at three points to achieve a stable setting of the anti-shake motor.

[0093] In a possible implementation, the movable carrier is provided with a first groove. The connecting member is located in the first groove. In this way, the connecting member is not easily dislodged from the movable carrier.

[0094] In one possible implementation, grease is provided between the connector and the first groove. This further reduces friction between the connector and the fixed support, thereby better achieving a super-slip connector system. Furthermore, the connector is less likely to fall out of the first groove.

[0095] In a possible implementation, the fixed carrier has a magnetic member, the movable carrier is provided with a magnetic member, and the magnetic attraction between the magnetic members maintains contact between the fixed carrier, the connector, and the movable carrier.

[0096] It is understood that the magnetic member and the magnetic member are disposed relative to each other. A magnetic attraction force can be generated between the magnetic member and the magnetic member. This magnetic attraction force can cause the movable carrier to tend to approach the fixed carrier, thereby maintaining contact between the fixed carrier, the connecting member, and the movable carrier. In this way, the movable carrier can stably attract the fixed carrier in the Z-axis direction, and the movable carrier has better stability when moving relative to the fixed carrier.

[0097] In a possible implementation, the magnetic element is a part of the fixed carrier.

[0098] In a possible implementation, there are multiple connecting members, and the multiple connecting members are arranged around the magnetic member. In this way, when the movable carrier moves relative to the fixed carrier, the stability of the movable carrier is better.

[0099] In one possible implementation, the anti-shake motor also includes a movable circuit board, which includes a first fixed part, an elastic part and a second fixed part, and the elastic part is connected between the first fixed part and the second fixed part; the movable carrier is fixed to the first fixed part, and the fixed carrier is fixed to the second fixed part; the image sensor module is fixed to the side of the first fixed part away from the movable carrier.

[0100] It is understandable that when the movable carrier moves relative to the fixed carrier along the first direction X, the elastic portion of the movable circuit board is deformed along the first direction X. The image sensor module and the first fixed portion of the movable circuit board can follow the movable carrier to move along the first direction X. When the movable carrier moves relative to the fixed carrier along the second direction Y, the elastic portion of the movable circuit board is deformed along the second direction Y. The image sensor module and the first fixed portion of the movable circuit board can follow the movable carrier to move along the second direction Y. Therefore, the movable carrier can control the image sensor module to move along a plane perpendicular to the third direction Z (i.e., the XY plane) through the movable circuit board. When the camera module collects ambient light, if the electronic device generates jitter in the XY plane due to external force, the movement of the image sensor module on the XY plane can be controlled to offset the jitter stroke of the camera module in the XY plane, so as to avoid or reduce the position offset of the camera module caused by the jitter, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0101] In one possible implementation, the elastic portion is spiral, zigzag, or curved. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion. The movement stroke of the movable circuit board is less restricted, which is conducive to realizing the setting of a movable carrier with a large anti-shake stroke. In addition, the spiral-shaped low-K value elastic portion can effectively compress the dimensions in the X and Y axes while maintaining a small size in the Z axis direction, reducing crosstalk in the XY plane movement and optimizing the electromagnetic drive performance and power consumption performance.

[0102] In a possible implementation, the length of the elastic portion is greater than half the circumference of the edge of the first fixing portion. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion.

[0103] In one possible implementation, the elastic portion surrounds at least half of the edge of the first fixing portion, or the elastic portion surrounds the edge of the first fixing portion in multiple turns. In this way, the length of the elastic portion can be increased, thereby significantly reducing the elastic coefficient of the elastic portion.

[0104] In one possible implementation, the movable circuit board further includes a reinforcement portion located on the first fixing portion, and the movable carrier is fixed to the reinforcement portion. It is understood that the reinforcement portion may be a steel plate or other metal plate. The reinforcement portion can enhance the overall strength of the first fixing portion.

[0105] In one possible implementation, the first bracket further includes a fixed protrusion, which is protruding from the base plate and located on a side of the base plate away from the first protrusion and / or the second protrusion; the fixed protrusion passes through the movable circuit board and is fixedly connected to the image sensor module. In this way, on the one hand, the assembly tolerance chain between the image sensor module and the first bracket is shorter, the assembly tolerance between the image sensor module and the first bracket is smaller, and the image sensor module and the base plate of the first bracket can be largely in the same plane. On the other hand, when the movable carrier moves in the XY plane, the movable carrier can directly drive the movement of the image sensor module, and the movement of the image sensor module is less affected by the movable circuit board.

[0106] In a possible implementation manner, the driving coil is electrically connected to the second fixing portion of the movable circuit board through the motor circuit board.

[0107] It is understood that in this embodiment, where the drive coil is electrically connected to the exterior of the image sensor assembly, the motor circuit board need not be electrically connected to the first fixing portion and the elastic portion of the movable circuit board. In this embodiment, the driver chip can be directly electrically connected to the second fixing portion 3 of the movable circuit board. This solution, where the driver chip is electrically connected to the exterior of the image sensor assembly, is simpler and easier to mass-produce.

[0108] In one possible implementation, the anti-shake motor includes a driver chip that is fixed to and electrically connected to a motor circuit board, with the input and output ends of the drive coil forming a current loop through the motor circuit board and the driver chip.

[0109] In a possible implementation, the fixed carrier includes a top plate, a first side plate and a second side plate that are oppositely disposed, and the top plate is connected between the first side plate and the second side plate;

[0110] The top plate is arranged at an obtuse angle to the first side plate, and / or the top plate is arranged at an obtuse angle to the second side plate;

[0111] The driving coil is fixed to the top plate.

[0112] It can be understood that by setting the top plate and the first side plate at an obtuse angle, and / or the top plate and the second side plate at an obtuse angle, the fixed carrier is roughly in the shape of a "pyramid". At this time, the first driving magnetic component is arranged on one side of the top plate of the fixed carrier, the driving coil is arranged on the top plate of the fixed carrier, and the second driving magnetic component is located on the bottom side of the fixed carrier. In this way, in this implementation, the anti-shake motor has a "pyramid" stacked structure, the second driving magnetic component is arranged at the top layer, the first driving coil, the second driving coil, the third driving coil and the fourth driving coil are arranged from top to bottom in the middle layer, and the first driving magnetic component is arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupling image sensor.

[0113] In a third aspect, an image sensor assembly is provided. The image sensor assembly includes an image sensor module and the anti-shake motor described in the first aspect above, wherein the image sensor module is fixed to a movable carrier. Alternatively, the image sensor assembly includes an image sensor module and the anti-shake motor described in the second aspect above, wherein the image sensor module is fixed to a movable carrier.

[0114] It can be understood that when the movable carrier moves along the first direction X, the image sensor module can follow the movable carrier to move along the first direction X. When the movable carrier moves along the second direction Y relative to the fixed carrier, the image sensor module can follow the movable carrier to move along the second direction Y. Therefore, the movable carrier can control the image sensor module to move along a plane perpendicular to the third direction Z (that is, the XY plane). When the image sensor assembly is applied to a camera module, if the camera module generates jitter in the XY plane, the movement of the image sensor module on the XY plane can be controlled to offset the jitter stroke generated by the camera module in the XY plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0115] Furthermore, when the movable carrier is driven to rotate clockwise relative to the fixed carrier, the movable carrier drives the image sensor module to rotate clockwise. In this embodiment, by controlling the direction and magnitude of the current in the second sub-drive coil of the second drive coil to obtain a compensating driving force for counterclockwise rotation of the movable carrier relative to the fixed carrier, rotation compensation of the movable carrier about the Z axis is achieved. At this time, the image sensor module also rotates about the Z axis to compensate for the jitter caused by the camera module's rotation about the Z axis, thereby avoiding or reducing positional offset of the camera module caused by jitter, thereby achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0116] In one possible implementation, the image sensor module is fixed to a side of the movable carrier away from the first drive coil. In this way, the image sensor module is less likely to interfere with the anti-shake motor.

[0117] Alternatively, the image sensor module is fixed to the side of the movable carrier away from the first driving magnetic member. In this way, the image sensor module is not likely to interfere with the anti-shake motor.

[0118] In a fourth aspect, a camera module is provided. The camera module includes a first optical element and the above-described image sensor assembly. The image sensor assembly is located on the image side of the first optical element.

[0119] It can be understood that if the camera module shakes in the XY plane, the anti-shake motor can control the movement of the image sensor module in the XY plane to offset the shaking stroke of the camera module in the XY plane, so as to avoid or reduce the position offset of the camera module caused by shaking, thereby realizing optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0120] In one possible implementation, the camera module further includes a first optical path conversion element. The first optical path conversion element is located between the first optical element and the image sensor assembly. The first optical path conversion element is used to change the direction of the optical axis of the camera module.

[0121] In one possible implementation, the first optical path conversion element includes a first side surface, a second side surface, and a third side surface connected to each other. After passing through the first optical element, light enters the first optical path conversion element, is totally reflected by the second side surface of the first optical path conversion element, and is reflected by the third side surface of the first optical path conversion element before propagating to the image sensor assembly.

[0122] The image sensor assembly is located on the side of the third side of the first optical path conversion element. This effectively utilizes the space provided by the third side of the first optical path conversion element. Furthermore, the image sensor assembly and the first optical path conversion element overlap in the thickness direction of the electronic device, minimizing the thickness of the electronic device.

[0123] In a possible implementation, the first side surface and the second side surface of the first light path conversion element are vertically arranged, and the third side surface of the first light path conversion element is an inclined surface.

[0124] In a possible implementation, the camera module further includes a second optical conversion element, which is located on the object side of the first optical element, and the second optical conversion element is used to change the optical axis direction of the camera module.

[0125] In a fifth aspect, an electronic device is provided. The electronic device includes a device housing and the camera module described above, wherein the camera module is disposed in the device housing. It is understood that the camera module of the electronic device of this implementation has an anti-shake motor with a larger rated stroke. BRIEF DESCRIPTION OF THE DRAWINGS

[0203] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0204] The object side, with the lens as the boundary, the side where the object is located is the object side, and the surface of the lens close to the object side is called the object side;

[0205] Image side: With the lens as the boundary, the side where the image of the object is located is called the image side, and the surface of the lens close to the image side is called the image side;

[0206] The optical axis is an axis running perpendicularly through the center of a lens. It's the axis running through the centers of each lens element. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens would have all the rays converge at a single point behind the lens. This point is the focal point.

[0207] Sensor shift optical image stabilizer (SOIS);

[0208] TSA (Trace suspension assembly) is an integrated component that integrates the reed and signal line.

[0209] Movingtilt: The dynamic tilt of the movable platform (tilt around the x-axis or y-axis) that characterizes the motion stability of the SOIS;

[0210] ShiftZ: The displacement fluctuation of the movable platform in the Z direction (optical axis direction) that characterizes the motion stability of the SOIS.

[0211] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," "connected," and "connected" should be understood broadly. For example, "connected" can be a detachable or non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the two parts are connected to each other and the relative positional relationship remains unchanged after the connection. "Moveable connection" means that the two parts are connected to each other and can move relative to each other after the connection, and the positional relationship can change. "Rotational connection" means that the two parts are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that the two parts are connected to each other and can slide relative to each other after the connection. In addition, two components are formed into an integrated structure through an integral molding process, which means that during the process of forming one of the two components, the component is connected to the other component, and the two components do not need to be connected by further processing (such as bonding, welding, snap connection, screw connection). Component A and component B can be arranged relative to each other so that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, and projection C and projection D can at least partially overlap. In some embodiments, the majority overlap can be any of the following: projection C is completely within projection D. Alternatively, projection D is completely within projection C. Alternatively, projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0212] The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", "upper", "lower", etc., are only used to refer to the directions in the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. For those skilled in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0213] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship. "Multiple" means at least two.

[0214] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0215] As shown in FIG1 , electronic device 1000 may be a device with a camera function, such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet. The electronic device 1000 of the embodiment shown in FIG1 is described using a mobile phone as an example.

[0216] FIG2 is a partial cross-sectional view of the electronic device 1000 shown in FIG1 taken along line AA in one embodiment.

[0217] As shown in Figures 1 and 2, the electronic device 1000 may include a camera module 100, a device housing 200, and a screen 300. The camera module 100 may be a rear camera module or a front camera module. Figure 2 schematically shows the camera module 100 through a dotted frame. It will be understood that Figure 1 and the related figures below only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and the figures below. In addition, when the electronic device 1000 is a device of some other form, the electronic device 1000 may also not include the screen 300.

[0218] As shown in Figures 1 and 2, in some embodiments, screen 300 is mounted on device housing 200 and, together with device housing 200, encloses the interior of electronic device 1000. The interior of electronic device 1000 can be used to house components of electronic device 1000, such as a battery, receiver, or microphone. Screen 300 can be either flat or curved.

[0219] For example, the camera module 100 can be located inside the electronic device 1000. The device housing 200 has a light-transmitting portion 201. The shape of the light-transmitting portion 201 is not limited to the circular shape shown in FIG1 ; it can also be an elliptical or irregular shape. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 can capture the light entering the interior of the electronic device 1000.

[0220] As shown in Figure 2, the camera module 100 includes an image sensor assembly 101, a first optical path conversion element 102, and a first optical element 103, arranged sequentially from the image side to the object side. It will be appreciated that the first optical path conversion element 102 can be used to change the direction of the optical axis of the camera module 100. The image sensor assembly 101 can be used to convert image information carried by ambient light into electrical signals.

[0221] It is understood that the first optical element 103, the first optical path conversion element 102, and the image sensor assembly 101 can form an integrated camera module 100. Thus, compared to a camera module 100 in which the first optical element 103, the first optical path conversion element 102, and the image sensor assembly 101 are separately provided, the camera module 100 of this embodiment is smaller in size, facilitating a miniaturized design of the camera module 100, thereby conserving internal space within the electronic device 1000.

[0222] Exemplarily, the first optical element 103 may include one or more lens groups. When the first optical element 103 includes multiple lens groups, at least one lens group may be movable along the optical axis. For example, as shown in FIG2 , the first optical element 103 includes a first lens group 1031 and a second lens group 1032. The first lens group 1031 may be movable along the optical axis. The second lens group 1032 may be a fixed lens group.

[0223] As shown in FIG2 , the first optical path conversion element 102 can illustratively include a prism. The first optical path conversion element 102 includes a first side surface 1021, a second side surface 1022, and a third side surface 1023, which are connected to each other. The first side surface 1021 of the first optical path conversion element 102 can face the first optical element 103. It will be understood that at least a portion of the light enters the first optical element 103, passes through the first optical element 103, then enters the first optical path conversion element 102 via the first side surface 1021 of the first optical path conversion element 102, and then propagates to the image sensor assembly 101 after being totally reflected by the third side surface 1023 of the first optical path conversion element 102 and reflected by the second side surface 1022 of the first optical path conversion element 102.

[0224] For example, the second side 1022 of the first optical path conversion element 102 can face the screen 300. The image sensor assembly 101 is located on the side of the third side 1023 of the first optical path conversion element 102. This effectively utilizes the space provided by the third side 1023 of the first optical path conversion element 102. Furthermore, the image sensor assembly 101 and the first optical path conversion element 102 overlap in the thickness direction of the electronic device 1000, so the location of the image sensor assembly 101 does not increase the thickness of the electronic device 1000.

[0225] In one embodiment, the first side surface 1021 and the second side surface 1022 of the first light path conversion element 102 are vertically arranged, and the third side surface 1023 of the first light path conversion element 102 is an inclined surface.

[0226] FIG3 is a schematic structural diagram of an embodiment of the image sensor assembly 101 shown in FIG2 .

[0227] Referring to FIG. 3 in conjunction with FIG. 2 , the image sensor assembly 101 includes a top surface 10a and a bottom surface 10d disposed in opposite directions, as well as a first side surface 10b and a second side surface 10c disposed in opposite directions. The top surface 10a and the bottom surface 10d of the image sensor assembly 101 are connected between the first side surface 10b and the second side surface 10c of the image sensor assembly 101. The bottom surface 10d of the image sensor assembly 101 is disposed opposite the third side surface 1023 of the first optical path conversion element 102.

[0228] It will be appreciated that, in one embodiment, the image sensor assembly 101 does not include the top surface 10a. In this case, the first side surface 10b and the second side surface 10c of the image sensor assembly 101 are directly connected and perpendicular to each other. This results in a large volume of the image sensor assembly 101, which is not conducive to miniaturization. In this embodiment, by forming the top surface 10a on the image sensor assembly 101, the image sensor assembly 101 can eliminate the space on the side where the top surface 10a of the image sensor assembly 101 is located. This results in a smaller volume of the image sensor assembly 101, which is conducive to miniaturization.

[0229] Exemplarily, the first side surface 10b of the image sensor assembly 101 is arranged at an acute angle to the bottom surface 10d. It is understandable that, in one embodiment, if the length of the bottom surface 10d of the image sensor assembly 101 is kept unchanged and the first side surface 10b of the image sensor assembly 101 is perpendicular to the bottom surface 10d of the image sensor assembly 101, then the first side surface 10b of the image sensor assembly 101 will easily increase the height of the camera module 100 (that is, the first side surface 10b of the image sensor assembly 101 will extend out of the dotted box of Figure 2). In this embodiment, by setting the first side surface 10b of the image sensor assembly 101 at an acute angle to the bottom surface 10d, the first side surface 10b of the image sensor assembly 101 is prevented from significantly increasing the height of the camera module 100.

[0230] Exemplarily, the second side surface 10c of the image sensor assembly 101 is arranged at an acute angle to the bottom surface 10d. It is understandable that, in one embodiment, if the length of the bottom surface 10d of the image sensor assembly 101 is kept unchanged and the second side surface 10c of the image sensor assembly 101 is made perpendicular to the bottom surface 10d of the image sensor assembly 101, then the second side surface 10c of the image sensor assembly 101 will easily increase the length of the camera module 100 (that is, the second side surface 10c of the image sensor assembly 101 will extend out of the dotted box of FIG. 2 ). In this embodiment, by arranging the second side surface 10c of the image sensor assembly 101 at an acute angle to the bottom surface 10d, the second side surface 10c of the image sensor assembly 101 is prevented from significantly increasing the height of the camera module 100.

[0231] Exemplarily, the included angle between the first side surface 10 b and the bottom surface 10 d of the image sensor assembly 101 is smaller than the included angle between the second side surface 10 c and the bottom surface 10 d of the image sensor assembly 101 .

[0232] For example, the first side surface 10b of the image sensor assembly 101 is disposed at an obtuse angle to the top surface 10a. And / or, the second side surface 10c of the image sensor assembly 101 is disposed at an obtuse angle to the top surface 10a. In this way, the image sensor assembly 101 can fully utilize the space located on the third side surface 1023 of the first optical path conversion element 102.

[0233] Exemplarily, the first side surface 10 b of the image sensor assembly 101 is arranged in parallel with the second side surface 1022 of the first optical path conversion element 102 .

[0234] Exemplarily, the second side surface 10 c of the image sensor assembly 101 is arranged in parallel with the first side surface 1021 of the first optical path conversion element 102 .

[0235] For example, the image sensor assembly 101 may be shaped like a pyramid.

[0236] 2 , the camera module 100 further includes a second optical path conversion element 104. The second optical path conversion element 104 is located on the object side of the first optical element 103. The second optical path conversion element 104 can also be used to change the direction of the optical axis of the camera module 100.

[0237] Exemplarily, the second optical path conversion element 104 may include a prism. The light-entering side of the second optical path conversion element 104 is disposed opposite the light-transmitting portion 201. Light passing through the light-transmitting portion 201 can enter the second optical path conversion element 104 and, after reflection from the second optical path conversion element 104, travel to the first optical element 103. After passing through the first optical element 103, the light enters the first optical path conversion element 102 and, after total internal reflection from the third side surface 1023 of the first optical path conversion element 102 and reflection from the second side surface 1022, travels to the image sensor assembly 101.

[0238] In other embodiments, the camera module 100 may not include the second optical path conversion element 104. The light incident side of the first optical element 103 is disposed opposite to the light-transmitting portion 201. In this case, light passing through the light-transmitting portion 201 can directly enter the first optical element 103.

[0239] In other embodiments, the second optical path conversion element 104 may further include an anti-shake motor. The anti-shake motor is used to drive the prism of the second optical path conversion element 104 to achieve optical image stabilization of the camera module 100.

[0240] It is understood that the above is only a schematic illustration of an embodiment of the image sensor assembly 101 being applied to the camera module 100. In other embodiments, the image sensor assembly 101 may also be applied to camera modules 100 having other structures. This application does not limit this in detail.

[0241] FIG. 4 is a partially exploded schematic diagram of an embodiment of the image sensor assembly 101 shown in FIG. 3 .

[0242] As shown in Figures 3 and 4, the image sensor assembly 101 includes an anti-shake motor 10, an image sensor module 20, an upper housing 30, and a lower housing 40. For ease of description, the width of the image sensor assembly 101 is defined as the X-axis. The length of the image sensor assembly 101 is defined as the Y-axis. The thickness of the image sensor assembly 101 is defined as the Z-axis. It will be appreciated that the coordinate system of the image sensor assembly 101 can be flexibly configured according to specific practical needs.

[0243] It is understandable that the anti-shake motor 10 can control the image sensor module 20 to move along a plane perpendicular to the third direction Z (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 generates jitter in the XY plane due to external force, the anti-shake motor 10 can be used to control the movement of the image sensor module 20 in the XY plane to offset the jitter stroke generated by the camera module 100 in the XY plane, so as to avoid or reduce the position bias of the camera module 100 caused by the jitter. The camera module 100 of the present application can control the movement of the image sensor module 20 in the XY plane through the anti-shake motor 10 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0244] FIG. 5 is a partially exploded schematic diagram of an embodiment of the anti-shake motor 10 shown in FIG. 4 .

[0245] As shown in FIG. 5 , the anti-shake motor 10 includes a fixed carrier 11 , a movable carrier 12 (also called a moving carrier), a driving magnetic member 13 , a first driving coil 14 , and a second driving coil 15 .

[0246] Exemplarily, the movable carrier 12 includes a first bracket 121 and a second bracket 122 .

[0247] Exemplarily, the driving magnetic component 13 includes a first driving magnetic component 131 and a second driving magnetic component 132 .

[0248] Exemplarily, the second driving coil 15 includes a first sub-driving coil 151 and a second sub-driving coil 152 .

[0249] It is understood that the anti-shake motor 10 may include more or fewer structures. For example, when the anti-shake motor 10 includes more structures, it may further include a first circuit board 16, a second circuit board 17, a movable circuit board 18 (also known as a TSA or elastic circuit board), a rolling element 191, and a magnetic element 192. For example, the rolling element 191 may be a single ball, a ball group formed by multiple balls, a sliding shaft, or a protruding structure.

[0250] Figure 6 is a schematic diagram of the structure of the fixed carrier 11 shown in Figure 5 at different angles. Figure 7 is a schematic diagram of the structure of the fixed carrier 11 shown in Figure 5 at another angle.

[0251] As shown in Figures 6 and 7, the fixed carrier 11 includes a top plate 112, a first side plate 113 and a second side plate 114 disposed opposite each other, and a third side plate 115 and a fourth side plate 116 disposed opposite each other. The top plate 112 is connected between the first side plate 113 and the second side plate 114, and is also connected between the third side plate 115 and the fourth side plate 116. The third side plate 115 and the fourth side plate 116 are connected between the first side plate 113 and the second side plate 114. The top plate 112, the first side plate 113, the second side plate 114, the third side plate 115, and the fourth side plate 116 enclose an inner space of the fixed carrier 11.

[0252] Exemplarily, the top plate 112 and the first side plate 113 are arranged at an obtuse angle. And / or, the top plate 112 and the second side plate 114 are arranged at an obtuse angle.

[0253] Exemplarily, the fixed carrier 11 is provided with a receiving groove 117 . An opening of the receiving groove 117 is formed on the top plate 112 .

[0254] Exemplarily, the fixed carrier 11 is provided with a first through hole 118 and a second through hole 119 spaced apart from each other. The first through hole 118 and the second through hole 119 connect the inner space of the fixed carrier 11 to the outer space. In one embodiment, the first through hole 118 is formed in the first side plate 113. The second through hole 119 is formed in the second side plate 114.

[0255] FIG8 is a partially exploded schematic diagram of an embodiment of the fixing carrier 11 shown in FIG6 .

[0256] As shown in FIG8 , the fixed carrier 11 includes a metal member 11a and an insulating member 11b. The metal member 11a can be embedded in the insulating member 11b. For example, the metal member 11a can be integrally formed with the insulating member 11b through methods such as insert molding. This improves the overall strength of the fixed carrier 11.

[0257] Exemplarily, the insulating member 11b includes a first insulating portion 111b, a second insulating portion 112b and a third insulating portion 113b disposed opposite each other, and a fourth insulating portion 114b and a fifth insulating portion 115b disposed opposite each other. The first insulating portion 111b is connected between the second insulating portion 112b and the third insulating portion 113b, and is connected between the fourth insulating portion 114b and the fifth insulating portion 115b. The fourth insulating portion 114b and the fifth insulating portion 115b are connected between the second insulating portion 112b and the third insulating portion 113b.

[0258] As shown in Figure 8, the metal member 11a includes a first metal member 111a, a second metal member 112a, and a third metal member 113a. For example, the first metal member 111a can be embedded in the first insulating portion 111b. The second metal member 112a can be embedded in the second insulating portion 112b. The third metal member 113a can be embedded in the third insulating portion 113b.

[0259] Referring to Figure 8 , and in conjunction with Figures 6 and 7 , the first metal member 111a and the first insulating portion 111b may form a top plate 112 for fixing the carrier 11. The second metal member 112a and the second insulating portion 112b may form a first side plate 113 for fixing the carrier 11. The third metal member 113a and the third insulating portion 113b may form a second side plate 114 for fixing the carrier 11. The fourth insulating portion 114b may form a third side plate 115 for fixing the carrier 11. The fifth insulating portion 115b may form a fourth side plate 116 for fixing the carrier 11. A first through hole 118 and a second through hole 119 may be formed in the fourth insulating portion 114b and the fifth insulating portion 115b, respectively. A portion of the first metal member 111a and the first insulating portion 111b enclose a receiving groove 117.

[0260] As shown in Figure 8, the first metal member 111a includes a main body 114a and a plurality of extensions 115a. The plurality of extensions 115a are connected to the edges of the main body 114a at intervals. For example, the plurality of extensions 115a can be bent relative to the main body 114a.

[0261] As shown in Figures 6 to 8, at least a portion of the main body 114a of the first metal member 111a forms a magnetic isolation sheet 111. The magnetic isolation sheet 111 can be exposed relative to the first insulating portion 111b. The magnetic isolation sheet 111 includes a first surface 1111 and a second surface 1112 disposed in opposite directions. The first surface 1111 of the magnetic isolation sheet 111 is the surface of the top plate 112 facing the inner side of the fixed carrier 11, and the second surface 1112 of the magnetic isolation sheet 111 is the surface of the top plate 112 facing away from the outer side of the fixed carrier 11. In other embodiments, the magnetic isolation sheet 111 can also be embedded in the first insulating portion 111b.

[0262] Exemplarily, the plurality of extension portions 115 a of the first metal member 111 a may be exposed relative to the first insulating portion 111 b .

[0263] It is understandable that the above is only a schematic introduction to the structure of a fixed carrier 11. In other embodiments, the structure of the fixed carrier 11 is not specifically limited.

[0264] FIG. 9 is a first schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in FIG. 4 .

[0265] 9 and FIG. 7 , the first driving magnetic member 131 of the driving magnetic member 13 is fixed to the first surface 1111 of the magnetic isolation plate 111 , that is, the first driving magnetic member 131 is located in the inner space of the fixed carrier 11 .

[0266] Exemplarily, the first drive magnetic component 131 may include multiple magnets, and the multiple magnets are arranged in the first direction X. The implementation structure of the first drive magnetic component 131 can be various. For example, the first drive magnetic component 131 may include at least three magnets, and among the three adjacent magnets, the polarization directions of the two magnets located on the sides are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet located in the middle is directed from one magnet to the other magnet. It will be understood that Figure 9 only schematically shows six magnets. For another example, the first drive magnetic component 131 may be a Halbach magnet array. For another example, the first drive magnetic component 131 may adopt a dual magnet structure, for example, consisting of two magnets, and the polarity directions of the two magnets are opposite. It will be understood that when the first drive magnetic component 131 adopts a combination array arrangement of multiple groups of Halbach magnets, the distribution of magnetic flux lines is further compressed, effectively improving the magnetic thrust and improving the utilization rate of magnetic flux lines.

[0267] Exemplarily, the first driving magnetic component 131 may include a magnet, that is, the first driving magnetic component 131 may adopt a single magnet structure, for example, composed of a magnet, the magnet including two parts with opposite polarity directions, and the two parts may be arranged in the first direction X. The magnet may be manufactured using a bipolar magnetization process. In addition, the two parts with opposite polarity directions may form a magnet unit. A magnet may include multiple magnet units. The multiple magnet units are arranged in the first direction X.

[0268] FIG10 is a schematic structural diagram of a portion of the anti-shake motor 10 shown in FIG9 at another angle.

[0269] 10 , in conjunction with FIG6 , the second driving magnetic member 132 of the driving magnetic member 13 is fixed to the second surface 1112 of the magnetic isolation plate 111 . In one embodiment, the second driving magnetic member 132 is located in the receiving groove 117 of the fixed carrier 11 .

[0270] It is understood that in this embodiment, the first driving magnetic member 131 is fixed to the first surface 1111 of the magnetic isolation plate 111, and the second driving magnetic member 132 is fixed to the second surface 1112 of the magnetic isolation plate 111, thereby fixing the driving magnetic member 13 to the fixed carrier 11. In addition, the first driving magnetic member 131 and the second driving magnetic member 132 can be separately fixed to different positions of the fixed carrier 11, and the magnetic isolation plate 111 can separate the first driving magnetic member 131 and the second driving magnetic member 132.

[0271] Exemplarily, the second drive magnetic component 132 may include a plurality of magnets, and the plurality of magnets are arranged in the second direction Y. The implementation structure of the second drive magnetic component 132 may be various. For example, the second drive magnetic component 132 may include at least three magnets. Among two adjacent magnets, the polarity directions of the two magnets are opposite. It will be understood that Figure 10 only schematically shows three magnets. For another example, the second drive magnetic component 132 may adopt a dual magnet structure, for example, consisting of two magnets, and the polarity directions of the two magnets are opposite. For another example, the second drive magnetic component 132 may be a Halbach magnet array. For another example, the second drive magnetic component 132 may include at least three magnets, and among the three adjacent magnets, the polarization directions of the two magnets located on the sides are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet located in the middle is directed from one magnet to the other magnet. It is understandable that when the second driving magnetic component 132 adopts a combination array arrangement of multiple groups of Halbach magnets, the distribution of magnetic flux lines is further compressed, the magnetic thrust is effectively increased, and the utilization rate of magnetic flux lines is improved.

[0272] Exemplarily, the second driving magnetic component 132 may include a magnet, that is, the second driving magnetic component 132 may adopt a single magnet structure, for example, composed of a magnet, the magnet including two parts with opposite polarity directions, and the two parts may be arranged in the second direction Y. The magnet may be manufactured using a bipolar magnetization process. In addition, the two parts with opposite polarity directions may form a magnet unit. A magnet may include multiple magnet units. The multiple magnet units are arranged in the second direction Y.

[0273] FIG11 is a schematic structural diagram of the first bracket 121 shown in FIG5 at another angle.

[0274] As shown in FIG11 , the first bracket 121 includes a bottom plate 1211 , a first protrusion 1212 , and a second protrusion 1213 . The first protrusion 1212 and the second protrusion 1213 are protruded from the same side of the bottom plate 1211 .

[0275] For example, the bottom plate 1211 is provided with a first avoidance hole 1214. The first avoidance hole 1214 can be located between the first protrusion 1212 and the second protrusion 1213. There can be two first avoidance holes 1214. The shape of the first avoidance holes 1214 can be an elongated strip. In other embodiments, the position, size, number, and shape of the first avoidance holes 1214 are not specifically limited.

[0276] For example, the first bracket 121 has a plurality of first position-limiting protrusions 1215. The plurality of first position-limiting protrusions 1215 can limit the position of other structural components. The position, size, number, and shape of the first position-limiting protrusions 1215 are not specifically limited. Furthermore, the first position-limiting protrusions 1215 can also be replaced with a groove structure.

[0277] Exemplarily, the first bracket 121 has a plurality of first pin ends 1216. The plurality of first pin ends 1216 can be used to electrically connect to other structural components.

[0278] It is understandable that FIG11 only schematically labels some of the first limiting protrusions 1215 and the first pin ends 1216 .

[0279] FIG. 12 is a second schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in FIG. 4 .

[0280] As shown in FIG12 , the anti-shake motor 10 includes an anti-shake driving chip 193 . The anti-shake driving chip 193 is fixed to the first circuit board 16 and electrically connected to the first circuit board 16 .

[0281] Exemplarily, the anti-shake motor 10 includes a first position sensor 194 and a second position sensor 195. Both the first position sensor 194 and the second position sensor 195 are fixed to and electrically connected to the first circuit board 16. The first position sensor 194 and the second position sensor 195 are fixed to the first bracket 121 of the movable carrier 12 via the first circuit board 16.

[0282] For example, the first circuit board 16 is provided with a second avoidance hole 161. The number of the second avoidance holes 161 can be two. The shape of the second avoidance holes 161 can be an elongated strip. In other embodiments, the position, size, number, and shape of the second avoidance holes 161 are not specifically limited.

[0283] Exemplarily, the first circuit board 16 has a plurality of second pin ends 162. The plurality of second pin ends 162 can be used to electrically connect to other structural components.

[0284] FIG13 is a third schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in FIG4 .

[0285] Referring to FIG13 , in conjunction with FIG11 and FIG12 , the first circuit board 16 is fixed to the movable carrier 12. For example, the first circuit board 16 is fixed to the bottom plate 1211 of the first bracket 121. At least a portion of the first circuit board 16 may be located between the first bump 1212 and the second bump 1213.

[0286] Exemplarily, the first circuit board 16 is provided with a second avoidance hole 161 which is arranged opposite to the first avoidance hole 1214 of the first bracket 121 .

[0287] For example, the multiple first limiting protrusions 1215 of the first bracket 121 can cooperate with each other to abut against the first circuit board 16, thereby limiting the position of the first circuit board 16. In this case, the connection between the first circuit board 16 and the first bracket 121 is more stable. For example, there are two first limiting protrusions 1215. The two first limiting protrusions 1215 are arranged in the first direction X and abut against the first circuit board 16 in the first direction X.

[0288] FIG14 is a fourth schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in FIG4 .

[0289] As shown in FIG14 , the first driving coil 14 is fixed to the first circuit board 16 and is electrically connected to the first circuit board 16 . The first driving coil 14 is fixed to the bottom plate 1211 of the first bracket 121 through the first circuit board 16 .

[0290] Exemplarily, the input end and the output end of the first driving coil 14 form a current loop through the first circuit board 16 and the anti-shake driving chip 193 .

[0291] For example, the multiple first limiting protrusions 1215 of the first bracket 121 can cooperate with each other to abut against the first drive coil 14, thereby limiting the position of the first drive coil 14. In this case, the connection between the first drive coil 14 and the first circuit board 16 is more stable. For example, the first limiting protrusions 1215 of the first bracket 121 are located on the inner side of the first drive coil 14 and abut against the first drive coil 14 in the first direction X.

[0292] FIG. 15 is a fifth partial structural diagram of an embodiment of the anti-shake motor 10 shown in FIG. 4 .

[0293] As shown in Figure 15, the bottom plate 1211 of the first bracket 121 is provided with a rolling element groove 1217. The rolling element 191 is located in the rolling element groove 1217, that is, the rolling element 191 is disposed on the movable carrier 12. For example, there are three rolling elements 191 and three rolling element grooves 1217. The three rolling elements 191 are disposed in a one-to-one correspondence within the three rolling element grooves 1217.

[0294] Exemplarily, grease is provided between the rolling element 191 and the rolling element groove 1217 .

[0295] As shown in Figure 15, the bottom plate 1211 of the first bracket 121 is provided with a receiving groove 1218. The receiving groove 1218 is spaced apart from the rolling element groove 1217. The anti-shake motor 10 includes a magnetic element 192. The magnetic element 192 is located in the receiving groove 1218, which means that the movable carrier 12 is provided with the magnetic element 192. Exemplarily, there are three magnetic elements 192 and three receiving grooves 1218. The three magnetic elements 192 are disposed in a one-to-one correspondence within the three receiving grooves 1218.

[0296] Exemplarily, the three magnetic members 192 are disposed around the three rolling members 191 in a one-to-one correspondence.

[0297] It can be understood that by arranging both the rolling member 191 and the magnetic member 192 on the first bracket 121, that is, the rolling member 191 and the magnetic member 192 are arranged on the same structural member, when the first bracket 121 undergoes relative movement, the relative positions of the rolling member 191 and the magnetic member 192 are not likely to change to a large extent.

[0298] FIG. 16 is a schematic structural diagram of the second bracket 122 shown in FIG. 5 at different angles.

[0299] As shown in FIG. 16 , the second bracket 122 includes a top surface 1221 and a bottom surface 1222 disposed in opposite directions.

[0300] For example, the bottom surface 1222 of the second bracket 122 is provided with a plurality of second limiting protrusions 1223. The plurality of second limiting protrusions 1223 can limit the position of other structural members. The position, size, number and shape of the second limiting protrusions 1223 are not specifically limited.

[0301] For example, a limiting post 1224 is protruded from the bottom surface 1222 of the second bracket 122. The limiting post 1224 can be used to limit the position of other structural members. The position, size, number and shape of the limiting post 1224 are not specifically limited.

[0302] For example, the second bracket 122 is provided with a fixing hole 1225. The number of the fixing hole 1225 can be one or more. The position, size, number and shape of the fixing hole 1225 are not specifically limited.

[0303] FIG17 is a schematic structural diagram of the second circuit board 17 shown in FIG5 at another angle.

[0304] As shown in Figure 17, the second circuit board 17 has a plurality of third pin ends 171. The plurality of third pin ends 171 can be used to electrically connect to other structural components.

[0305] Exemplarily, the second circuit board 17 is provided with a plurality of limiting holes 172. The position, size, number and shape of the limiting holes 172 are not specifically limited.

[0306] As shown in FIG17 , the anti-shake motor 10 includes a third position sensor 173 . The third position sensor 173 is fixed to the second circuit board 17 and electrically connected to the second circuit board 17 .

[0307] FIG18 is a fifth partial structural diagram of an embodiment of the anti-shake motor 10 shown in FIG4 .

[0308] 18 , in conjunction with FIG16 and FIG17 , the second circuit board 17 is fixed to the bottom surface 1222 of the second bracket 122 . At this time, the third position sensor 173 is fixed to the second bracket 122 via the second circuit board 17 .

[0309] For example, the plurality of second limiting protrusions 1223 of the second bracket 122 can cooperate with each other to abut against the second circuit board 17, thereby limiting the position of the second circuit board 17. In this case, the connection between the second circuit board 17 and the second bracket 122 is more stable. For example, the plurality of second limiting protrusions 1223 are arranged in the first direction X and abut against the second circuit board 17 in the first direction X.

[0310] For example, the limiting post 1224 of the second bracket 122 can be inserted into the limiting hole 172 of the second circuit board 17 to further limit the second circuit board 17, thereby making the connection between the second bracket 122 and the second circuit board 17 more stable. For example, the limiting post 1224 of the second bracket 122 can be riveted into the limiting hole 172 of the second circuit board 17.

[0311] FIG19 is a sixth schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in FIG4 .

[0312] As shown in FIG19 , the second driving coil 15 is fixed to the second circuit board 17 and is electrically connected to the second circuit board 17 . At this time, the second driving coil 15 is fixed to the second bracket 122 via the second circuit board 17 .

[0313] Exemplarily, the first sub-driving coil 151 and the second sub-driving coil 152 are both fixed to the second circuit board 17 at intervals, and are both electrically connected to the second circuit board 17 .

[0314] For example, the plurality of second limiting protrusions 1223 of the second bracket 122 can cooperate with each other to abut against the second drive coil 15, thereby limiting the position of the second drive coil 15. In this case, the connection between the second drive coil 15 and the second circuit board 17 is more stable. For example, the second limiting protrusions 1223 of the second bracket 122 are located on the inner side of the second drive coil 15 and abut against the second drive coil 15 in the first direction X.

[0315] Fig. 20 is a seventh schematic diagram of a partial structure of an embodiment of the anti-shake motor 10 shown in Fig. 4. Fig. 21 is a schematic diagram of the structure of the partial anti-shake motor 10 shown in Fig. 20 at another angle.

[0316] As shown in FIG. 20 and FIG. 21 , the second bracket 122 is fixedly connected to the first protrusion 1212 and the second protrusion 1213 , and is opposite to and spaced from the bottom plate 1211 .

[0317] Exemplarily, the second bracket 122 may be fixedly connected to the first bump 1212 and the second bump 1213 by bonding.

[0318] Exemplarily, the first bump 1212 , the second bump 1213 and the second bracket 122 all include metal parts. The metal parts of the first bump 1212 and the second bump 1213 are both welded to the metal part of the second bracket 122 .

[0319] For example, the fixing post 1212a of the first protrusion 1212 is inserted into one fixing hole 1225 of the second bracket 122. The fixing post 1213a of the second protrusion 1213 is inserted into another fixing hole 1225 of the second bracket 122. At this time, the connection between the second bracket 122 and the first bracket 121 is more stable.

[0320] As shown in Figures 20 and 21 , the first drive coil 14 and the second drive coil 15 are arranged facing each other. Furthermore, the second drive coil 15 forms a current loop with the anti-shake drive chip 193 via the second circuit board 17 (see Figure 19 ), the conductive member in the first bracket 121 , and the first circuit board 16 .

[0321] It is understood that the first drive coil 14 and the second drive coil 15 are arranged facing each other, which may mean that the winding plane of the first drive coil 14 faces the winding plane of the second drive coil 15. For example, the winding planes of the first drive coil 14 and the second drive coil 15 may both be arranged parallel to the XY plane.

[0322] Exemplarily, the lengthwise extension direction of the first drive coil 14 and the lengthwise extension direction of the second drive coil 15 are perpendicular to each other.

[0323] Fig. 22 is a partial structural schematic diagram eight of an embodiment of the anti-shake motor 10 shown in Fig. 4. Fig. 23 is a partial cross-sectional view of an embodiment of the anti-shake motor 10 shown in Fig. 22 taken along line BB.

[0324] As shown in Figures 22 and 23 , the movable carrier 12 is movably connected to the fixed carrier 11. For example, the movable carrier 12 can be movably connected to the fixed carrier 11 via a rolling member 191.

[0325] Exemplarily, the rolling element 191 is disposed in contact with the extension portion 115a of the fixed carrier 11 ( FIG. 8 illustrates the extension portion 115a at different angles). It is understood that because the extension portion 115a of the fixed carrier 11 is made of metal, the friction between the rolling element 191 and the fixed carrier 11 is relatively low, which facilitates stable movement of the movable carrier 12 relative to the fixed carrier 11.

[0326] Exemplarily, there are three rolling elements 191 , which are distributed at different positions to support and fix the carrier 11 at three points, so as to achieve a stable arrangement of the anti-shake motor 10 .

[0327] For example, grease is provided between the rolling element 191 and the rolling element groove 1217. This further reduces friction between the rolling element 191 and the fixed carrier 11, thereby further improving the super-slip system for the rolling element. Furthermore, the rolling element 191 is less likely to fall out of the rolling element groove 1217. In other embodiments, the rolling element 191 may also be integrally formed with the movable carrier 12.

[0328] Exemplarily, the magnetic isolation sheet 111 of the top plate 112 of the fixed carrier 11 is located between the bottom plate 1211 of the first bracket 121 and the second bracket 122. That is, a portion of the fixed carrier 11 is located between the bottom plate 1211 of the first bracket 121 and the second bracket 122. The magnetic isolation sheet 111 of the top plate 112 of the fixed carrier 11 is spaced apart from and disposed opposite to the bottom plate 1211 of the first bracket 121 and the second bracket 122.

[0329] For example, the bottom plate 1211 of the first bracket 121 is located in the inner space of the fixed carrier 11. The first protrusion 1212 of the first bracket 121 can pass through the first through-hole 118 of the fixed carrier 11 from the inner space of the fixed carrier 11 and extend to the outer space of the fixed carrier 11. Furthermore, the positional relationship between the second protrusion 1213 of the first bracket 121 (see FIG. 21 ) and the second through-hole 119 of the fixed carrier 11 (see FIG. 6 ) can be referred to in the positional relationship between the first protrusion 1212 of the first bracket 121 and the first through-hole 118 of the fixed carrier 11. The details will not be repeated here.

[0330] Exemplarily, the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15. The first driving coil 14 and the second driving coil 15 both face the driving magnetic member 13 to drive the movable carrier 12 to move relative to the fixed carrier 11. The first surface 1111 of the magnetic isolation sheet 111 faces the first driving coil 14, and the second surface 1112 of the magnetic isolation sheet 111 faces the second driving coil 15.

[0331] FIG. 24 is a partially exploded view of an embodiment of the anti-shake motor 10 shown in FIG. 5 .

[0332] Referring to FIG. 24 and FIG. 23 , the first driving coil 14 faces the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. The first driving coil 14 and the first driving magnetic member 131 may constitute a first driving mechanism of the anti-shake motor 10 .

[0333] It can be understood that the first drive coil 14 is arranged facing the first drive magnetic part 131, which means that the winding plane of the first drive coil 14 faces the first drive magnetic part 131. For example, the winding plane of the first drive coil 14 can be arranged parallel to the XY plane. For example, the first drive magnetic part 131 can have two opposite polarity directions (as shown by the dotted line with arrows in Figure 24, wherein Figure 24 schematically shows that the first drive magnetic part 131 includes three groups of two opposite polarity directions.). The polarity direction of the first drive magnetic part 131 can be arranged perpendicular to the winding plane of the first drive coil 14. Among them, the coils in the two sections of a first drive coil 14 can be respectively arranged corresponding to the two polarity directions of the first drive magnetic part 131, and the currents in the coils in the two sections (as shown by the solid line a with arrows in Figure 24) flow in opposite directions. The side of the first drive magnetic member 131 facing the first drive coil 14 includes a south pole (S) and a north pole (N), and the side of the first drive magnetic member 131 facing away from the first drive coil 14 correspondingly includes a north pole (N) and a south pole (S). It can be understood that since the polarity of the side of the first drive magnetic member 131 facing the first drive coil 14 is blocked, Figure 24 only schematically shows the polarity of the side of the first drive magnetic member 131 facing away from the first drive coil 14. In addition, the number of first drive coils 14 is three. The three first drive coils 14 are arranged one by one in correspondence with the three groups of two opposite polarity directions.

[0334] Referring to FIG. 24 , in conjunction with FIG. 23 , the first position sensor 194 can be used to detect a change in the first magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. In this case, the first position sensor 194 or the anti-shake driving chip 193 can determine the displacement of the movable carrier 12 relative to the fixed carrier 11 in the first direction X based on the change in the first magnetic field.

[0335] Referring to FIG. 24 , in conjunction with FIG. 23 , the second position sensor 195 can be used to detect a change in the second magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. In this case, the second position sensor 195 or the anti-shake driving chip 193 can determine the displacement of the movable carrier 12 relative to the fixed carrier 11 in the first direction X based on the change in the second magnetic field.

[0336] It is understandable that in the process of confirming the displacement of the movable carrier 12 relative to the fixed carrier 11 along the first direction X, the first position sensor 194 or the second position sensor 195 can be used alone or simultaneously.

[0337] Referring to FIG. 24 , in conjunction with FIG. 23 , the first sub-drive coil 151 of the second drive coil 15 faces the second drive magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 in the second direction Y. The first sub-drive coil 151 of the second drive coil 15 and the second drive magnetic member 132 constitute a second drive mechanism of the anti-shake motor 10 .

[0338] It is understood that the first sub-drive coil 151 is arranged facing the second drive magnetic member 132, which means that the winding plane of the first sub-drive coil 151 faces the second drive magnetic member 132. For example, the winding plane of the first sub-drive coil 151 can be arranged parallel to the XY plane. Exemplarily, the second drive magnetic member 132 can have two opposite polarity directions (indicated by the dotted line with arrows in Figure 24), and the polarity direction of the second drive magnetic member 132 is arranged perpendicular to the winding plane of the first sub-drive coil 151. Among them, the coils in two sections of a first sub-drive coil 151 can be respectively arranged to correspond to the two polarity directions of the second drive magnetic member 132, and the currents in the coils in the two sections (indicated by the solid line b with arrows in Figure 24) flow in opposite directions. The side of the second drive magnetic member 132 facing the first sub-drive coil 151 includes a north pole (N) and a south pole (S), and the side of the second drive magnetic member 132 facing away from the first sub-drive coil 151 includes a south pole (S) and a north pole (N). It will be appreciated that, because the polarity of the side of the second drive magnetic member 132 facing away from the first sub-drive coil 151 is obscured, Figure 24 schematically illustrates only the polarity of the side of the second drive magnetic member 132 facing the first sub-drive coil 151. Furthermore, Figure 24 schematically illustrates that the second drive magnetic member 132 has three polarity directions, with adjacent polarity directions being opposite. There is only one first sub-drive coil 151.

[0339] Referring to FIG. 24 , in conjunction with FIG. 23 , the third position sensor 173 can be used to detect a change in the third magnetic field of the second driving magnetic member 132 when the movable carrier 12 moves relative to the fixed carrier 11 in the second direction Y. In this case, the third position sensor 173 or the anti-shake driving chip 193 can determine the displacement of the movable carrier 12 relative to the fixed carrier 11 in the second direction Y based on the change in the third magnetic field.

[0340] Exemplarily, the driving force generated by the cooperation between the first sub-drive coil 151 and the second drive magnetic member 132 is less than the driving force generated by the cooperation between the first drive coil 14 and the first drive magnetic member 131. In one embodiment, when the number of turns is the same, the number of first sub-drive coils 151 is less than the number of first drive coils 14. And / or, when the number is the same, the number of turns of the first sub-drive coil 151 is less than the number of turns of the first drive coil 14. And / or, the volume of the second drive magnetic member 132 is less than the volume of the first drive magnetic member 131. And / or, when the dimensions are the same, the number of second drive magnetic members 132 is less than the number of first drive magnetic members 131.

[0341] Referring to FIG. 24 and FIG. 23 , the second sub-drive coil 152 of the second drive coil 15 faces the second drive magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. The second sub-drive coil 152 of the second drive coil 15 and the second drive magnetic member 132 constitute a third drive mechanism of the anti-shake motor 10.

[0342] It will be understood that the second sub-drive coil 152 is disposed facing the second drive magnetic member 132, meaning that the winding plane of the second sub-drive coil 152 faces the second drive magnetic member 132. For example, the winding plane of the second sub-drive coil 152 can be disposed parallel to the XY plane. For example, there are two second sub-drive coils 152. The two second sub-drive coils 152 can be arranged in the first direction X. The coils in the two sections of the two second sub-drive coils 152 can be disposed corresponding to the two polarity directions of the second drive magnetic member 132, respectively. The currents in the coils in the two sections (the solid line c with an arrow in FIG. 24 illustrates the current in the first second sub-drive coil 152, and the solid line d with an arrow illustrates the current in the second second sub-drive coil 152) flow in opposite directions. The side of the second drive magnetic member 132 facing the second sub-drive coil 152 includes a north pole (N) and a south pole (S), and the side of the second drive magnetic member 132 facing away from the second sub-drive coil 152 includes a south pole (S) and a north pole (N), respectively. The two second sub-driving coils 152 share the two polarity directions of the second driving magnetic member 132. In addition, the two second sub-driving coils 152 and one first sub-driving coil 151 share the second driving magnetic member 132.

[0343] It will be appreciated that by connecting the two second sub-drive coils 152 in series, the currents flowing through the two second sub-drive coils 152 are directed in opposite directions. Consequently, when power is applied to the two second sub-drive coils 152, the forces acting on them are opposite. For example, when the first second sub-drive coil 152 is subjected to a force in the positive direction of the Y-axis, the second second sub-drive coil 152 is subjected to a force in the negative direction of the Y-axis. At this point, the torque exerted by the two second sub-drive coils 152 on the movable carrier 12 causes the movable carrier 12 to rotate relative to the fixed carrier 11.

[0344] It is understood that by providing the second sub-drive coil 152 of the second drive coil 15 and the second drive magnetic member 132, rotation compensation about the Z-axis direction is achieved. For example, when the movable carrier 12 rotates clockwise relative to the fixed carrier 11, the direction and magnitude of the current in the second sub-drive coil 152 of the second drive coil 15 can be controlled to obtain a compensating driving force that rotates the movable carrier 12 counterclockwise relative to the fixed carrier 11, thereby achieving rotation compensation for the movable carrier 12 about the Z-axis direction.

[0345] Referring to FIG. 24 , in conjunction with FIG. 23 , the first position sensor 194 can be used to detect a change in the first magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. The second position sensor 195 can be used to detect a change in the second magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. The first position sensor 194 and the second position sensor 195 cooperate with each other to detect the rotation angle of the movable carrier 12 relative to the fixed carrier 11.

[0346] In one embodiment, the first position sensor 194 or the second position sensor 195 or the anti-shake driving chip 193 can determine the rotation angle of the movable carrier 12 relative to the fixed carrier 11 based on the first magnetic field variation and the second magnetic field variation.

[0347] FIG25A is a partial cross-sectional view of another embodiment of the anti-shake motor 10 shown in FIG22.

[0348] As shown in FIG25A , the upper housing 30 is illustratively fixed to the fixed carrier 11. The upper housing 30 can cover at least a portion of the second bracket 122 and the gap between the second bracket 122 and the fixed carrier 11. The upper housing 30 can enhance the aesthetics and overall integrity of the anti-shake motor 10. Furthermore, if the second driving magnetic component 132 of the driving magnetic component 13 is exposed through the gap between the second bracket 122 and the fixed carrier 11, the upper housing 30 can also be used to cover and protect the second driving magnetic component 132.

[0349] As shown in FIG25A , the upper shell 30 can also cover the first through hole 118 ( FIG3 and FIG6 illustrate the first through hole 118 at different angles) and the second through hole 119 ( FIG6 illustrates the second through hole 119 at different angles) of the fixed carrier 11 .

[0350] Referring to FIG. 25A and FIG. 3 , the surface of the upper housing 30 facing away from the second bracket 122 can form the top surface 10a of the image sensor assembly 101. A portion of the upper housing 30 and the first side plate 113 of the fixed carrier 11 can collectively form the first side surface 10b of the image sensor assembly 101. A portion of the upper housing 30 and the second side plate 114 of the fixed carrier 11 can collectively form the second side surface 10c of the image sensor assembly 101.

[0351] FIG25B is a partial cross-sectional view of the anti-shake motor 10 shown in FIG22 at line CC according to an embodiment.

[0352] Referring to FIG. 25B , and in conjunction with FIG. 8 , the plurality of extensions 115a of the first metal member 111a of the fixed carrier 11 form magnetic elements. Specifically, the plurality of extensions 115a of the first metal member 111a of the fixed carrier 11 are made of a magnetic material, i.e., a material capable of generating magnetic attraction with a magnet or other magnetic component, such as a ferromagnetic material. In this case, the magnetic element may be part of the metal portion of the fixed carrier 11.

[0353] As shown in FIG25B , the magnetic member 192 is disposed opposite the extension 115a. A magnetic attraction force is generated between the magnetic member 192 and the extension 115a. This magnetic attraction force can cause the movable carrier 12 to tend to approach the fixed carrier 11. This allows the movable carrier 12 to stably attract the fixed carrier 11 in the Z-axis direction, providing greater stability when the movable carrier 12 moves relative to the fixed carrier 11.

[0354] For example, when there are multiple magnetic members 192 and multiple extending portions 115 a , the multiple magnetic members 192 are disposed opposite to the multiple extending portions 115 a in a one-to-one correspondence.

[0355] Exemplarily, the extension portion 115a is disposed facing the magnetic member 192, so that the relative area between the magnetic member 192 and the extension portion 115a is larger, which is beneficial to increasing the magnitude of the magnetic attraction force between the magnetic member 192 and the extension portion 115a.

[0356] It is understandable that the position of the magnetic component 192 can be reasonably set to better avoid and balance the overall magnetic interference of the anti-shake motor 10, that is, to avoid magnetic interference between the magnetic component 192 and the driving magnetic component 13 as much as possible.

[0357] It is understandable that the extension portion 115a of the fixed carrier 11 can provide a smooth contact surface for the rolling element 191 and also serve as a magnetic element for the magnetic element 192. The extension portion 115a of the fixed carrier 11 has a "multi-purpose" function.

[0358] It is understood that by arranging both the rolling element 191 and the magnetic element 192 on the movable carrier 12, the relative positions of the rolling element 191 and the magnetic element 192 are less likely to change significantly when the movable carrier 12 moves relative to the fixed carrier 11. In particular, when there are multiple rolling elements 191 and multiple magnetic elements 192, the relative positions of the contact centers of the multiple rolling elements 191 and the fixed carrier 11 and the centers of magnetic attraction of the multiple magnetic elements 192 are less likely to change. In this case, the movable carrier 12 has better stability when moving relative to the fixed carrier 11, that is, stable pressure and smooth movement are achieved between the movable carrier 12 and the fixed carrier 11.

[0359] Fig. 26 is a schematic diagram of the structure of the movable circuit board 18 shown in Fig. 5 at another angle. Fig. 27 is a partially exploded schematic diagram of the movable circuit board 18 shown in Fig. 5 in one embodiment.

[0360] As shown in Figures 26 and 27, the movable circuit board 18 includes a first fixing portion 181, an elastic portion 182, a second fixing portion 183, and an electrical connection portion 184. The elastic portion 182 is connected between the first fixing portion 181 and the second fixing portion 183. The electrical connection portion 184 is fixed to and electrically connected to the first fixing portion 181, and is electrically connected to the exterior of the movable circuit board 18 through the elastic portion 182 and the second fixing portion 183.

[0361] Exemplarily, there are two electrical connection portions 184 , each of which has a plurality of pin ends 1841 .

[0362] For example, the elastic portion 182 is in a spiral, broken line or curved shape. In this way, the length of the elastic portion 182 can be increased, thereby greatly reducing the elastic coefficient of the elastic portion 182.

[0363] Exemplarily, the length of the elastic portion 182 is greater than half of the circumference of the edge of the first fixing portion 181 .

[0364] Exemplarily, the elastic portion 182 surrounds at least half of the edge of the first fixing portion 181 , or the elastic portion 182 surrounds the edge of the first fixing portion 181 in multiple circles.

[0365] For example, the elastic coefficient of the movable circuit board 18 in the length direction is K Y , KY The size is in the range of 25 to 35. For example, the elastic coefficient of the movable circuit board 18 in the length direction is K Y It can be 30.

[0366] And / or, the elastic coefficient of the movable circuit board 18 in the width direction is K X , K X The size is in the range of 85 to 100. For example, the elastic coefficient of the movable circuit board 18 in the length direction is K X It can be 93.

[0367] Exemplarily, the movable circuit board 18 further includes a reinforcement portion 185. The reinforcement portion 185 is secured to the first securing portion 181. The reinforcement portion 185 may be a steel plate or other sheet metal member. The reinforcement portion 185 defines a clearance area 1851. The electrical connection portion 184 passes through the clearance area 1851, meaning that the reinforcement portion 185 surrounds the electrical connection portion 184.

[0368] Exemplarily, the reinforcing portion 185 may be fixed to the first fixing portion 181 by adhesive.

[0369] Fig. 28 is a ninth partial structural diagram of an embodiment of the anti-shake motor 10 shown in Fig. 4. Fig. 29 is a partial cross-sectional view of an embodiment of the anti-shake motor 10 shown in Fig. 28 taken along line DD.

[0370] 28 and 29 , in conjunction with FIG26 and 27 , the movable carrier 12 is fixed to the first fixing portion 181 of the movable circuit board 18. It is understood that the movable carrier 12 may have no connection with either the elastic portion 182 or the second fixing portion 183 of the movable circuit board 18.

[0371] Exemplarily, the first bracket 121 of the movable carrier 12 is fixed to the first fixing portion 181 via the reinforcing portion 185 .

[0372] In one embodiment, both the movable carrier 12 and the first fixing portion 181 include metal parts, and the metal part of the movable carrier 12 can be welded to the metal part of the first fixing portion 181 .

[0373] It is understood that when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X, the elastic portion 182 of the movable circuit board 18 deforms in the first direction X. The first fixed portion 181 of the movable circuit board 18 can follow the movement of the movable carrier 12 relative to the fixed carrier 11 in the first direction X. When the movable carrier 12 moves relative to the fixed carrier 11 in the second direction Y, the elastic portion 182 of the movable circuit board 18 deforms in the second direction Y. The first fixed portion 181 of the movable circuit board 18 can follow the movement of the movable carrier 12 relative to the fixed carrier 11 in the second direction Y.

[0374] In one embodiment, the elastic coefficient of the movable circuit board 18 in the width direction is K X , K X The size is in the range of 85 to 100. The elastic coefficient of the movable circuit board 18 in the length direction is K Y , K Y The size of is in the range of 25 to 35. At this time, the K of the movable circuit board 18 Y Less than K X .

[0375] It is understandable that due to the K of the movable circuit board 18 Y Less than K X , so that the travel of the movable carrier 12 relative to the fixed carrier 11 along the second direction Y is limited to be smaller than the travel of the movable carrier 12 relative to the fixed carrier 11 along the first direction X. In this case, the embodiment can better match the K of the movable circuit board 18 by setting the driving force generated by the first sub-driving coil 151 and the second driving magnetic member 132 to be smaller than the driving force generated by the first driving coil 14 and the first driving magnetic member 131. Y Less than K X For example, the number of the first sub-driving coils 151 and the number of the second driving magnetic members 132 can be set to be smaller, thereby facilitating a miniaturized configuration of the anti-shake motor 10 .

[0376] FIG30 is a partial structural diagram ten of an embodiment of the anti-shake motor 10 shown in FIG4 .

[0377] Referring to Figure 30 and in conjunction with Figure 27 , a portion of the electrical connection portion 184 of the movable circuit board 18 passes through the first avoidance hole 1214 (see Figure 11 ) of the first bracket 121 of the movable carrier 12 and is located within the second avoidance hole 161 (see Figure 12 ) of the first circuit board 16. The pin end 1841 of the electrical connection portion 184 is electrically connected to the second pin end 162 of the first circuit board 16.

[0378] It can be understood that the anti-shake drive chip 193 can be electrically connected to the electrical connection part 184 of the movable circuit board 18 through the first circuit board 16, and electrically connected to the outside of the anti-shake motor 10 through the first fixed part 181, the elastic part 182, and the second fixed part 183 of the movable circuit board 18.

[0379] Figure 31 is an exploded schematic diagram of an embodiment of the image sensor module 20 shown in Figure 4. Figure 32 is a partial structural schematic diagram of an embodiment of the image sensor module 20 shown in Figure 4. Figure 33 is a structural schematic diagram of the portion of the image sensor module 20 shown in Figure 32 from another angle.

[0380] As shown in Figures 31 to 33, the image sensor module 20 includes a module circuit board 21, an image sensor 22 (also known as a sensor), a filter holder 23, and a filter 24. It is understood that the image sensor 22 is also referred to as a photosensitive chip or a photosensitive element. The image sensor 22 can be used to capture ambient light that passes through the first optical path conversion element 102 and convert the image information carried by the ambient light into an electrical signal. It is understood that the image sensor module 20 can include fewer or more structures. For example, the image sensor module 20 can include fewer structures. The image sensor module 20 may not include the filter holder 23 and / or the filter 24. For another example, the image sensor module 20 may include more structures. The image sensor module 20 may also include electronic components. The electronic components may be capacitors, inductors, resistors, etc. The electronic components can be electrically connected to the image sensor 22.

[0381] In some embodiments, the image sensor 22 can be fixed to the module circuit board 21 and electrically connected to the module circuit board 21. At this time, signals can be transmitted between the image sensor 22 and the module circuit board 21. The filter holder 23 is fixedly connected to the module circuit board 21. The filter holder 23 and the image sensor 22 can be located on the same side of the module circuit board 21. The filter holder 23 is provided with a through hole 231. The filter 24 is fixedly connected to the filter holder 23. The filter 24 can be located in the through hole 231. The filter 24 is also arranged opposite to the image sensor 22. The filter 24 can be used to filter infrared light or blue light in the light before entering the image sensor 22, thereby ensuring that the image sensor 22 has better imaging quality.

[0382] FIG34 is a partial cross-sectional schematic diagram 1 of an embodiment of the image sensor assembly 101 shown in FIG3 at line EE.

[0383] As shown in Figure 34 , the image sensor module 20 is fixed to the first fixing portion 181 of the movable circuit board 18. The image sensor module 20 is located on a side of the first fixing portion 181 of the movable circuit board 18 that is away from the reinforcing portion 185. It is understood that the image sensor module 20 may have no connection to either the elastic portion 182 or the second fixing portion 183 of the movable circuit board 18.

[0384] Exemplarily, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing portion 181 of the movable circuit board 18 .

[0385] As shown in FIG34 , the image sensor module 20 is electrically connected to the first fixing portion 181 of the movable circuit board 18. For example, the image sensor 22 can be electrically connected to the first fixing portion 181 of the movable circuit board 18 via the module circuit board 21, and electrically connected to the exterior of the image sensor assembly 101 via the elastic portion 182 and the second fixing portion 183 of the movable circuit board 18.

[0386] Fig. 35 is a partial structural diagram of an embodiment of the image sensor assembly 101 shown in Fig. 3. Fig. 36 is a second partial cross-sectional diagram of an embodiment of the image sensor assembly 101 shown in Fig. 3 at line EE.

[0387] As shown in Figures 35 and 36 , the image sensor module 20 is located on the side of the first fixing portion 181 of the movable circuit board 18 that is away from the movable carrier 12. At this time, the image sensor module 20 is fixed to the movable carrier 12 via the movable circuit board 18. The image sensor module 20 is located on the side of the movable carrier 12 that is away from the first drive coil 14.

[0388] It is understood that when the movable carrier 12 moves along the first direction X, the elastic portion 182 of the movable circuit board 18 deforms along the first direction X. The image sensor module 20 and the first fixed portion 181 of the movable circuit board 18 can follow the movable carrier 12 in moving along the first direction X. When the movable carrier 12 moves along the second direction Y relative to the fixed carrier 11, the elastic portion 182 of the movable circuit board 18 deforms along the second direction Y. The image sensor module 20 and the first fixed portion 181 of the movable circuit board 18 can follow the movable carrier 12 in moving along the second direction Y. Therefore, the movable carrier 12 can control the image sensor module 20 to move along a plane perpendicular to the third direction Z (i.e., the XY plane) through the movable circuit board 18. When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the image sensor module 20 in the XY plane can be controlled to offset the vibrating stroke of the camera module 100 in the XY plane, so as to avoid or reduce the position offset of the camera module 100 caused by the vibration, thereby realizing optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0389] In addition, when the movable carrier 12 is driven to rotate clockwise relative to the fixed carrier 11, the movable carrier 12 drives the image sensor module 20 to rotate clockwise via the elastic portion 1821 of the movable circuit board 18. In this embodiment, by controlling the direction and magnitude of the current in the second sub-drive coil 152 of the second drive coil 15, a compensating driving force for the counterclockwise rotation of the movable carrier 12 relative to the fixed carrier 11 is obtained, thereby achieving rotation compensation of the movable carrier 12 around the Z-axis. At this time, the image sensor module 20 also performs rotation compensation around the Z-axis to offset the jitter stroke generated by the rotation of the camera module 100 around the Z-axis, thereby avoiding or reducing the position offset of the camera module 100 caused by jitter, thereby achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0390] FIG37 is a schematic structural diagram of the first bracket 121 shown in FIG5 at another angle.

[0391] As shown in Figure 38 , the first bracket 121 further includes a fixing protrusion 1219. The fixing protrusion 1219 is protruding from the bottom plate 1211 and is located on a side of the bottom plate 1211 away from the first protrusion 1212 (see Figure 11 ) and / or the second protrusion 1213. Exemplarily, the fixing protrusion 1219 is a square block. There are two fixing protrusions 1219. In other embodiments, the size, number, and shape of the fixing protrusions 1219 are not specifically limited.

[0392] Exemplarily, the two fixing protrusions 1219 may be located on both sides of the first avoidance hole 1214 .

[0393] FIG38 is a partial cross-sectional schematic diagram of an embodiment of the image sensor assembly 101 shown in FIG3 at line FF.

[0394] 37 and 38 , the fixing bump 1219 passes through the gap of the elastic portion 182 of the movable circuit board 18 and is fixedly connected to the image sensor module 20. For example, the module circuit board 21 of the image sensor module 20 is fixedly connected to the fixing bump 1219.

[0395] It will be appreciated that, by providing a protruding fixing bump 1219 on the bottom plate 1211 of the first bracket 121, the fixing bump 1219 passes through the movable circuit board 18 and is directly fixedly connected to the image sensor module 20. Thus, compared to a solution in which the image sensor module 20 is fixedly connected to the first bracket 121 via the movable circuit board 18, in this embodiment, on the one hand, the assembly tolerance chain between the image sensor module 20 and the first bracket 121 is shorter, the assembly tolerance between the image sensor module 20 and the first bracket 121 is smaller, and the image sensor module 20 and the bottom plate 1211 of the first bracket 121 can largely be in the same plane. On the other hand, when the movable carrier 12 moves in the XY plane, the movable carrier 12 can directly drive the movement of the image sensor module 20, and the movement of the image sensor module 20 is less affected by the movable circuit board 18.

[0396] FIG39 is a third partial cross-sectional schematic diagram of an embodiment of the image sensor assembly 101 shown in FIG3 at line EE.

[0397] As shown in Figure 39 , the fixed carrier 11 is fixed to the second fixing portion 183 of the movable circuit board 18. The fixed carrier 11 can be disconnected from the first fixing portion 181 and the elastic portion 182 of the movable circuit board 18. This provides a more stable connection between the anti-shake motor 10 and the image sensor module 20, improving the integrity of the anti-shake motor 10 and the image sensor module 20.

[0398] FIG40 is a fourth partial cross-sectional diagram of an embodiment of the image sensor assembly 101 shown in FIG3 at line EE.

[0399] As shown in Figure 40 , the lower housing 40 is fixedly connected to the fixed carrier 11. The lower housing 40 can be located on a side of the fixed carrier 11 away from the upper housing 30. In this case, the lower housing 40 and the upper housing 30 can be located on either side of the fixed carrier 11. The lower housing 40 can cover at least a portion of the first bracket 121 and the associated components thereon. It will be appreciated that the lower housing 40 can enhance the aesthetics and overall integrity of the anti-shake motor 10.

[0400] For example, the lower housing 40 is also fixedly connected to the second fixing portion 183 of the movable circuit board 18. A portion of the movable circuit board 18 can be located between the lower housing 40 and the fixed carrier 11. In this way, the lower housing 40 can also cover a portion of the movable circuit board 18. This improves the aesthetics and overall integrity of the anti-shake motor 10.

[0401] Please refer to FIG. 40 and combine it with FIG. 3 . The surface of the lower housing 40 facing away from the fixed carrier 11 can be used to form the bottom surface 10 b of the image sensor assembly 101 .

[0402] The above describes in detail the architecture of the image sensor assembly 101 in conjunction with the relevant drawings.

[0403] As shown in Figures 23 and 24, the present application provides a "sandwich"-like magnetic coil drive architecture. Specifically, the drive magnetic element 13 is fixed to the fixed carrier 11, and the first drive coil 14 and the second drive coil 15 are both fixed to the movable carrier 12, with the drive magnetic element 13 positioned between the first drive coil 14 and the second drive coil 15. It can be understood that, on the one hand, the magnetic flux lines on both sides of the drive magnetic element 13 can be fully utilized by the first drive coil 14 and the second drive coil 15. The high magnetic field utilization rate of the drive magnetic element 13 helps to increase the drive stroke of the anti-shake motor 10. On the other hand, compared to the scheme where the first drive coil 14 and the second drive coil 15 are arranged flat in the XY plane, the first drive coil 14, the drive magnetic element 13, and the second drive coil 15 of the present application are arranged sequentially in the Z-axis direction. This effectively utilizes the space in the Z-axis direction and reduces the dimensions in the XY-axis direction. This can significantly improve the space utilization in the Z-axis direction. The increased magnetic flux line utilization can also increase thrust, making it possible to apply anti-shake to telephoto modules with more compact space and larger rated stroke requirements.

[0404] As shown in Figures 23 and 24, the driving magnetic member 13 includes a first driving magnetic member 131 and a second driving magnetic member 132. The first driving coil 14 faces the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. The first sub-driving coil 151 of the second driving magnetic member 132 faces the second driving magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the second direction Y. In this way, the movable carrier 12 can move relative to the fixed carrier 11 along a plane perpendicular to the third direction Z (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the image sensor module 20 in the XY plane can be controlled to offset the jitter stroke of the camera module 100 in the XY plane, so as to avoid or reduce the position offset of the camera module 100 caused by the jitter, thereby achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0405] In addition, since the first driving magnetic component 131 and the second driving magnetic component 132 can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component 131 and the second driving magnetic component 132 will not affect each other, which is conducive to maximizing the number of the first driving magnetic component 131 and the second driving magnetic component 132.

[0406] It can be understood that the "pyramid" stacked anti-shake motor architecture of the present application has the first sub-drive coil 151 arranged at the top layer and a group of symmetrical series reverse coils (second sub-drive coil 152) are added to achieve rotation compensation to solve the image rotation problem. The middle layer is arranged from top to bottom with the second drive magnetic part 132, the magnetic isolation plate 111, and the first drive magnetic part 131. The first drive coil 14 and the image sensor module 20 are arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupling image sensor 22.

[0407] As shown in Figures 23 and 24 , the fixed carrier 11 includes a magnetic shielding plate 111. The first driving magnetic member 131 is fixed to the first surface 1111 of the magnetic shielding plate 111, and the second driving magnetic member 132 is fixed to the second surface 1112 of the magnetic shielding plate 111. In this way, the magnetic shielding plate 111 can effectively isolate the magnetic flux lines of the first and second driving magnetic members 131, 132 from crosstalk, ensuring the utilization rate of the magnetic flux lines of the first and second driving magnetic members 131, 132.

[0408] As shown in Figures 2 and 3, by arranging the image sensor assembly 101 on the side of the hypotenuse of the first optical path conversion element 102, the image sensor assembly 101 can effectively utilize the space on the hypotenuse of the first optical path conversion element 102, thereby improving space utilization. Furthermore, the image sensor assembly 101 and the first optical path conversion element 102 have an overlapping area in the thickness direction of the electronic device 1000, so the position of the image sensor assembly 101 is unlikely to increase the thickness of the electronic device 1000.

[0409] As shown in Figures 2 and 3, by configuring the image sensor assembly 101 to resemble a pyramid, the volume of the image sensor assembly 101 is significantly reduced, achieving a compact design. Furthermore, when the image sensor assembly 101 is positioned on the side of the hypotenuse of the first optical path conversion element 102, the larger bottom portion of the image sensor assembly 101 can be positioned close to the hypotenuse of the first optical path conversion element 102, while the smaller bottom portion of the image sensor assembly 101 can be positioned away from the hypotenuse of the first optical path conversion element 102, thereby maximizing utilization of the free space on the side of the hypotenuse of the first optical path conversion element 102. It will be appreciated that the image sensor assembly 101 of the present application ensures that the volume of the camera module 100 is not significantly increased while also maximizing utilization of the free space on the side of the hypotenuse of the first optical path conversion element 102, thereby improving overall telephoto module space utilization. Compared to conventional baseboard SOIS, the image sensor assembly 101 occupies less module height and length, optimizing module support space.

[0410] As shown in Figures 26 and 27 , this embodiment utilizes the first drive coil 14 and the first drive magnetic member 131 to generate a greater driving force, thereby addressing the issue of the movable circuit board 18 being limited in its travel due to its greater elastic modulus in the first direction X. For example, by providing a greater number of first drive magnetic members 131 with a greater number of magnets and a greater number of first drive coils 14, a greater driving force in the first direction X can be achieved.

[0411] In addition, in this embodiment, the first driving magnetic member 131 with more magnets and the first driving coils 14 with more magnets are arranged near the bottom of the image sensor assembly 101 to maximize the use of the empty space on the side where the hypotenuse of the first optical path conversion element 102 is located.

[0412] As shown in Figures 26 and 27 , this embodiment utilizes a first sub-drive coil 151 and second drive magnetic member 132 to generate a smaller drive force. This is to accommodate the requirement that the elastic modulus of the movable circuit board 18 in the second direction Y be smaller and the range of motion of the movable circuit board 18 be less restricted. For example, by providing fewer first drive magnetic members 131 with fewer magnets and fewer first drive coils 14, a smaller drive force in the second direction Y can be achieved.

[0413] In addition, in this embodiment, the second driving magnetic member 132 with fewer magnets and the second driving coils 15 with fewer magnets are arranged near the top of the image sensor assembly 101 to maximize the use of the empty space on the side where the hypotenuse of the first optical path conversion element 102 is located.

[0414] As shown in Figures 23 and 24, the first sub-drive coil 151 of the second drive coil 15 faces the second drive magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 in the second direction Y. The second sub-drive coil 152 of the second drive coil 15 faces the second drive magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. It can be understood that the second sub-drive coil 152 and the first sub-drive coil 151 share the second drive magnetic member 132, which greatly improves space utilization.

[0415] As shown in FIG26 and FIG27 , the present application provides a low K value TSA-rotation compensation design.

[0416] First, by designing the elastic portion 182 of the movable circuit board 18 into a spiral, zigzag, or curved shape, the length of the elastic portion 182 is increased, significantly reducing its spring constant. This minimizes the travel of the movable circuit board 18, facilitating a larger anti-shake travel for the movable carrier 12. Furthermore, the spiral, low-K elastic portion 182 maintains a small Z-axis dimension while effectively compressing the X and Y-axis dimensions, reducing crosstalk during XY motion and optimizing electromagnetic drive performance and power consumption.

[0417] In addition, in this embodiment, the second sub-driving coil 152 is arranged to face the second driving magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11 , thereby performing rotation compensation to suppress the rotation and crosstalk of the movable circuit board 18 .

[0418] As shown in Figures 26 and 27 , compared to conventional main camera stabilization solutions, the module circuit board 21, movable circuit board 18, first circuit board 16, and stabilization driver chip 193 of the image sensor module 20 in this solution are separated along the Z-axis. Furthermore, an electrical connection 184 is provided on the movable circuit board 18 to electrically connect the image sensor 22 and the stabilization driver chip 193, effectively utilizing the Z-axis (optical axis) space and further improving XY plane space utilization.

[0419] The structure of the image sensor assembly 101 is described in detail above with reference to the relevant drawings. The structure of the image sensor assembly 101 is described in detail below with reference to the relevant drawings. It is understood that the same technical content as above will not be described in detail below.

In other embodiments, the driving magnetic member 13 may not include the second driving magnetic member 132 and / or the third driving magnetic member 133 .

[0427] Exemplarily, the second drive coil 15 includes a first sub-drive coil 151, a second sub-drive coil 152, and a third sub-drive coil 153. In other embodiments, the second drive coil 15 may not include the second sub-drive coil 152 and / or the third sub-drive coil 153.

[0428] In one embodiment, the number of the first sub-drive coil 151 and the third sub-drive coil 153 of the second drive coil 15 is one.

In other embodiments, the number of the first sub-drive coil 151, the second sub-drive coil 152, and the third sub-drive coil 153 of the second drive coil 15 is not specifically limited.

[0429] It is understood that the anti-shake motor 10 may include more or fewer structures. For example, when the anti-shake motor 10 includes more structures, the anti-shake motor 10 may further include a movable circuit board 18 and a rolling element 191. In other embodiments, the rolling element 191 may also be replaced with a sliding shaft.

[0430] As shown in FIG42 , the movable circuit board 18 illustratively includes a first fixing portion 181, an elastic portion 182, a second fixing portion 183, and an electrical connection portion 184. The elastic portion 182 is connected between the first fixing portion 181 and the second fixing portion 183. The electrical connection portion 184 is fixed to and electrically connected to the first fixing portion 181, and is electrically connected to the exterior of the movable circuit board 18 through the elastic portion 182 and the second fixing portion 183.

[0431] 42 , illustratively, the first bracket 121 includes a bottom plate 1211 , a first protrusion 1212 , and a second protrusion 1213 . The first protrusion 1212 and the second protrusion 1213 are protruded from the same side of the bottom plate 1211 .

[0432] FIG43 is a partial structural schematic diagram 1 of an embodiment of the anti-shake motor 10 shown in FIG41 .

[0433] As shown in Figures 42 and 43 , the movable carrier 12 is fixed to the first fixing portion 181 of the movable circuit board 18. It is understandable that the movable carrier 12 may have no connection relationship with either the elastic portion 182 or the second fixing portion 183 of the movable circuit board 18.

[0434] Exemplarily, the bottom plate 1211 of the first bracket 121 of the movable carrier 12 is fixed on the first fixing portion 181 .

[0435] As shown in FIG43 , the first sub-drive coil 141, the second sub-drive coil 142, and the third sub-drive coil 143 of the first drive coil 14 are all fixed to the movable carrier 12. For example, the first sub-drive coil 141, the second sub-drive coil 142, and the third sub-drive coil 143 of the first drive coil 14 are all fixed to the bottom plate 1211 of the first bracket 121. The first sub-drive coil 141, the second sub-drive coil 142, and the third sub-drive coil 143 of the first drive coil 14 are arranged in the first direction X. The first sub-drive coil 141, the second sub-drive coil 142, and the third sub-drive coil 143 of the first drive coil 14 can be electrically connected to the first fixing portion 181 of the movable circuit board 18 via a circuit board, and then electrically connected to external components of the anti-shake motor 10 via the elastic portion 182 and the second fixing portion 183 of the movable circuit board 18.

[0436] FIG44 is a second schematic diagram of the partial structure of an embodiment of the anti-shake motor 10 shown in FIG41 .

[0437] As shown in FIG44 , the fixed carrier 11 is fixed to the second fixing portion 183 of the movable circuit board 18. The fixed carrier 11 may not be connected to the first fixing portion 181 or the elastic portion 182 of the movable circuit board 18.

[0443] Exemplarily, the first sub-driving coil 151 , the second sub-driving coil 152 and the third sub-driving coil 153 of the second driving coil 15 are all fixed to the bottom surface 1222 of the second bracket 122 .

[0444] Exemplarily, the second bracket 122 is provided with a receiving slot 1223 . The opening of the receiving slot 1223 is located at the bottom surface 1222 of the second bracket 122 . The first sub-driving coil 151 , the second sub-driving coil 152 , and the third sub-driving coil 153 of the second driving coil 15 are all located in each receiving slot 1223 .

[0445] FIG46 is a fourth partial structural diagram of an embodiment of the anti-shake motor 10 shown in FIG41 .

[0446] Referring to Figure 46 , and in conjunction with Figures 43 and 45 , the second bracket 122 is fixedly connected to the first and second protrusions 1212 and 1213, and is spaced apart from and opposite the base plate 1211. It will be appreciated that the connection between the second bracket 122 and the first and second protrusions 1212 and 1213 can be found in the connection between the second bracket 122 and the first and second protrusions 1212 and 1213 illustrated above in Figures 20 and 21 . The details will not be further described here.

[0447] Fig. 47 is a partial structural diagram 5 of an embodiment of the anti-shake motor 10 shown in Fig. 41. Fig. 48 is a partial exploded schematic diagram of an embodiment of the driving magnetic member 13, the first driving coil 14 and the second driving coil 15 shown in Fig. 47.

[0448] As shown in Figures 47 and 48, the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15.

[0449] Exemplarily, the first driving magnetic member 131 is located between the first sub-driving coil 141 of the first driving coil 14 and the first sub-driving coil 151 of the second driving coil 15. The first sub-driving coil 141 of the first driving coil 14 and the first sub-driving coil 151 of the second driving coil 15 both face the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. It can be understood that the driving method of the first sub-driving coil 141 of the first driving coil 14 and the first driving magnetic member 131, and the driving method of the first sub-driving coil 151 of the second driving coil 15 and the first driving magnetic member 131 can all be referred to the driving method of the first driving coil 14 and the first driving magnetic member 131 shown in Figure 24. The details will not be repeated here.

[0450] Exemplarily, the second driving magnetic member 132 is located between the second sub-driving coil 142 of the first driving coil 14 and the second sub-driving coil 152 of the second driving coil 15. The second sub-driving coil 142 of the first driving coil 14 and the second sub-driving coil 152 of the second driving coil 15 both face the second driving magnetic member 132 to drive the movable carrier to move relative to the fixed carrier 11 along the second direction Y. It can be understood that the driving method of the second sub-driving coil 142 of the first driving coil 14 and the second driving magnetic member 132, and the driving method of the second sub-driving coil 152 of the second driving coil 15 and the second driving magnetic member 132 can all be referred to the driving method of the first sub-driving coil 151 and the second driving magnetic member 132 shown in Figure 24. The details will not be repeated here.

[0451] Exemplarily, the third driving magnetic member 133 is located between the third sub-driving coil 143 of the first driving coil 14 and the third sub-driving coil 153 of the second driving coil 15. The third sub-driving coil 143 of the first driving coil 14 and the third sub-driving coil 153 of the second driving coil 15 face the third driving magnetic member 133 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. It can be understood that the driving method of the third sub-driving coil 143 of the first driving coil 14 and the third driving magnetic member 133, and the driving method of the third sub-driving coil 153 of the second driving coil 15 and the third driving magnetic member 133 can all be referred to the driving method of the second sub-driving coil 152 and the second driving magnetic member 132 shown in Figure 24. The details will not be repeated here.

[0452] The above describes in detail the architecture of the image sensor assembly 101 in conjunction with the relevant drawings.

[0453] As shown in Figures 47 and 48, the present application provides a drive architecture for magnetic coils resembling a "sandwich" structure. Specifically, the drive magnetic element 13 is fixed to the fixed carrier 11, and the first drive coil 14 and the second drive coil 15 are both fixed to the movable carrier 12, with the drive magnetic element 13 positioned between the first drive coil 14 and the second drive coil 15. It can be understood that, on the one hand, the magnetic flux lines on both sides of the drive magnetic element 13 can be fully utilized by the first drive coil 14 and the second drive coil 15. The high magnetic field utilization rate of the drive magnetic element 13 helps to increase the drive stroke of the anti-shake motor 10. On the other hand, compared to the scheme where the first drive coil 14 and the second drive coil 15 are arranged flat in the XY plane, the first drive coil 14, the drive magnetic element 13, and the second drive coil 15 of the present application are arranged sequentially in the Z-axis direction. This effectively utilizes the space in the Z-axis direction and reduces the dimensions in the XY-axis direction, significantly improving the space utilization in the Z-axis direction. This increased magnetic flux line utilization also increases thrust, making it possible to apply anti-shake to telephoto modules with more compact space and a larger rated stroke.

[0454] In addition, since the first driving magnetic component 131 and the second driving magnetic component 132 can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component 131 and the second driving magnetic component 132 will not affect each other, which is conducive to maximizing the number of the first driving magnetic component 131 and the second driving magnetic component 132.

[0455] The structure of the image sensor assembly 101 is described in detail above with reference to the relevant drawings. The structure of the image sensor assembly 101 is described in detail below with reference to the relevant drawings. It is understood that the same technical content as above will not be described in detail below.

[0456] FIG49 is a partially exploded schematic diagram of yet another embodiment of the image sensor assembly 101 shown in FIG2 .

[0457] As shown in FIG49 , the image sensor assembly 101 includes an anti-shake motor 10, an image sensor module 20, and an upper housing 30. For details on the configuration of the image sensor module 20 and the upper housing 30, please refer to the configuration of the image sensor module 20 and the upper housing 30 described above. Details will not be repeated here.

[0458] As shown in FIG49 , the anti-shake motor 10 includes a fixed carrier 11, a movable carrier 12, a driving magnetic member 13, a first driving coil 14, a second driving coil 15, and a movable circuit board 18. For details regarding the fixed carrier 11, the movable carrier 12, the driving magnetic member 13, the first driving coil 14, the second driving coil 15, and the movable circuit board 18, refer to the fixed carrier 11, the movable carrier 12, the driving magnetic member 13, the first driving coil 14, the second driving coil 15, and the movable circuit board 18 described above. However, the difference is that the driving magnetic member 13 includes a first driving magnetic member 131 and a second driving magnetic member 132, i.e., the driving magnetic member 13 does not include a third driving magnetic member 133. The first driving coil 14 includes a first sub-driving coil 141 and a second sub-driving coil 142, i.e., the first driving coil 14 does not include a third sub-driving coil 143. The second driving coil 15 includes a first sub-driving coil 151 and a second sub-driving coil 152, i.e., the second driving coil 15 does not include a third sub-driving coil 153.

[0459] In this embodiment, the movable carrier 12 is movably connected to the fixed carrier 11 via the guide bracket 196 to achieve the movement of the movable carrier 12 relative to the fixed carrier 11 in the XY plane. The details are as follows:

[0460] As shown in FIG49 , the anti-shake motor 10 further includes a guide bracket 196. The guide bracket 196 includes a first support portion 1961, a second support portion 1962, and a third support portion 1963. The first support portion 1961, the second support portion 1962, and the third support portion 1963 are connected to the first bracket 121 of the movable carrier 12 via a plurality of first support members 197, and are connected to the fixed carrier 11 via a plurality of second support members 198, so that the relative movement direction between the movable carrier 12 and the guide bracket 196 is different from the relative movement direction between the guide bracket 196 and the fixed carrier 11. It is understood that the shape of the guide bracket 196 is not limited to the rectangular shape shown in FIG49 ; for example, the guide bracket 196 may also be L-shaped.

[0461] Illustratively, the guide bracket 196 may be provided with a plurality of first slide shaft grooves 1964. The plurality of first slide shaft grooves 1964 are disposed toward the same side of the guide bracket 196. There may be three first slide shaft grooves 1964, one located on the first support portion 1961, the second support portion 1962, and the third support portion 1963. The first slide shaft grooves 1964 may extend parallel to the first direction X. The first slide shaft grooves 1964 may be recessed from a side surface of the corresponding support portion toward the interior of the support portion.

[0462] For example, the guide bracket 196 may further include a plurality of second slide grooves 1965, which are disposed away from the plurality of first slide grooves 1964. The number of second slide grooves 1965 may be three, with the three second slide grooves 1965 being located on the first support portion 1961, the second support portion 1962, and the third support portion 1963, respectively. The second slide grooves 1965 may extend parallel to the second direction Y. The second slide grooves 1965 may be recessed from the other side surface of the corresponding support portion toward the interior of the support portion.

[0463] As shown in FIG49 , the plurality of first support members 197 are disposed in a one-to-one correspondence in the plurality of first slide shaft grooves 1964 , and the plurality of second support members 198 are disposed in a one-to-one correspondence in the plurality of second slide shaft grooves 1965 .

[0464] Exemplarily, both the first support member 197 and the second support member 198 may be sliding shaft structures.

[0465] It is understandable that the movable carrier 12 is movably connected to the fixed carrier 11 via the guide bracket 196, and the movable carrier 12 is less likely to rotate relative to the fixed carrier 11. The movement of the movable carrier 12 is more stable.

[0466] It is understood that the above description combines the relevant drawings to introduce several structures of the image sensor assembly 101. The following description will introduce several more structures of the image sensor assembly 101.

[0467] For example, in each of the above embodiments, the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15. In other embodiments, the positions of the driving magnetic member 13, the first driving coil 14 and the second driving coil 15 can be swapped.

[0468] For another example, in each of the above embodiments, the movable carrier 12 and the fixed carrier 11 are pressed together by magnetic attraction. In other embodiments, the movable carrier 12 and the fixed carrier 11 may also be pressed together by elastic elements or other stabilizing means.

[0469] For example, in the above embodiments, the movable carrier 12 and the fixed carrier 11 are connected by a single rolling element super-slip solution. In other embodiments, the movable carrier 12 and the fixed carrier 11 can also be connected by multiple rolling element super-slip / DLC bumps / sliding shafts and other contact methods.

[0470] For another example, in each of the above embodiments, the positions of the magnetic member 192 and the magnetic member can be swapped.

[0471] The structure of the image sensor assembly 101 has been described in detail above with reference to the accompanying drawings. The following describes a further structure of the image sensor assembly 101 in detail with reference to the accompanying drawings. It should be understood that the design of the anti-shake motor 10 illustrated in Figures 5 to 49 can also be directly applied to the structural design of the anti-shake motor 50 illustrated below, unless there is a conflict.

[0472] Fig. 50 is a schematic diagram of the structure of yet another embodiment of the image sensor assembly 101 shown in Fig. 2. Fig. 51 is a partially exploded schematic diagram of an embodiment of the image sensor assembly 101 shown in Fig. 50.

[0473] As shown in Figures 50 and 51 , the image sensor assembly 101 includes an anti-shake motor 50, an image sensor module 20, an upper housing 30, and a lower housing 40. For ease of description, the width of the image sensor assembly 101 is defined as the X-axis. The length of the image sensor assembly 101 is defined as the Y-axis. The thickness of the image sensor assembly 101 is defined as the Z-axis. It will be appreciated that the coordinate system of the image sensor assembly 101 can be flexibly configured according to specific practical needs.

[0474] It is understandable that the anti-shake motor 50 can control the image sensor module 20 to move along a plane perpendicular to the third direction Z (i.e., the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the anti-shake motor 50 can be used to control the movement of the image sensor module 20 in the XY plane to offset the shaking stroke of the camera module 100 in the XY plane, so as to avoid or reduce the position bias of the camera module 100 caused by the shaking. The camera module 100 of the present application can control the movement of the image sensor module 20 in the XY plane through the anti-shake motor 50 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0475] FIG52 is a partially exploded schematic diagram of an embodiment of the anti-shake motor 50 shown in FIG51 .

[0476] As shown in FIG52 , the anti-shake motor 50 includes a fixed carrier 51, a movable carrier 52 (also referred to as a moving carrier), a drive coil 53, a first drive magnetic member 54, and a second drive magnetic member 55. It should be understood that FIG52 merely schematically illustrates some components of the anti-shake motor 50, and the actual shapes, sizes, and structures of these components are not limited by FIG52 .

[0477] Exemplarily, the movable carrier 52 includes a first bracket 521 and a second bracket 522 .

[0478] Exemplarily, the drive coil 53 includes a first drive coil 531, a second drive coil 532, a third drive coil 533, and a fourth drive coil 534. Exemplarily, there are three first drive coils 531, one second drive coil 532, two third drive coils 533, and one fourth drive coil 534. In other embodiments, the number of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 is not specifically limited. In other embodiments, the drive coil 53 may not include the third drive coil 533 and / or the fourth drive coil 534.

[0479] For example, there are two first driving magnetic members 54. In other embodiments, the number of the first driving magnetic members 54 is not specifically limited.

[0480] Exemplarily, the second driving magnetic component 55 includes a first sub-driving magnetic component 551 and a second sub-driving magnetic component 552. In one embodiment, there are two first sub-driving magnetic components 551. There is one second sub-driving magnetic component 552. In other embodiments, the number of first sub-driving magnetic components 551 and second sub-driving magnetic components 552 is not specifically limited. In other embodiments, the second driving magnetic component 55 may not include the second sub-driving magnetic component 552.

[0481] It is understandable that the anti-shake motor 50 can also include more structures. For example, when the anti-shake motor 50 includes more structures, the anti-shake motor 50 can also include a circuit board assembly 56, and / or a movable circuit board 57 (also called TSA, or elastic circuit board), and / or a connector 581, and / or a magnetic component 582. Exemplarily, the connector 581 can be a single ball, or a ball group formed by multiple balls, or a sliding shaft, or a protruding structure. The following description will be based on the example that the connector 581 is a ball. Exemplarily, the number of connectors 581 is three. The number of magnetic components 582 is one. In other embodiments, the number of connectors 581 and magnetic components 582 is not specifically limited.

[0482] For example, the circuit board assembly 56 may include a driver circuit board 561 and a driver chip 562. The circuit board assembly 56 may also include more structures. For example, the circuit board assembly 56 may also include a position sensor (not shown).

[0483] Figure 53 is a schematic diagram of the structure of the fixed carrier 51 shown in Figure 52 at another angle. Figure 54 is a schematic diagram of the structure of the fixed carrier 51 shown in Figure 52 at yet another angle. Figure 55 is a schematic diagram of the structure of the fixed carrier 51 shown in Figure 52 at yet another angle.

[0484] As shown in Figures 53 to 55, the fixed carrier 51 includes a top plate 511, a first side plate 512 and a second side plate 513 disposed opposite each other, and a third side plate 514 and a fourth side plate 515 disposed opposite each other. The top plate 511 is connected between the first side plate 512 and the second side plate 513, and is also connected between the third side plate 514 and the fourth side plate 515. The third side plate 514 and the fourth side plate 515 are connected between the first side plate 512 and the second side plate 513. The top plate 511, the first side plate 512, the second side plate 513, the third side plate 514, and the fourth side plate 515 enclose an inner space of the fixed carrier 51.

[0485] Illustratively, the top plate 511 and the first side plate 512 are arranged at an obtuse angle. And / or, the top plate 511 and the second side plate 513 are arranged at an obtuse angle.

[0486] Illustratively, the top plate 511 of the fixed carrier 51 is provided with mounting holes 5111. The mounting holes 5111 connect the inner space of the fixed carrier 51 to the outer space. Illustratively, there may be three mounting holes 5111. The three mounting holes 5111 are spaced apart and arranged along the X-axis. In other embodiments, the position, size, and shape of the mounting holes 5111 are not specifically limited.

[0487] It is understood that the fixed carrier 51 can be formed into an integrally formed structure by metal parts and insulating parts through insert-molding, etc. In this way, the overall strength of the fixed carrier 51 is better.

[0488] As shown in Figure 55, illustratively, the anti-shake motor 50 also includes a magnetic component 59. Exemplarily, the magnetic component 59 can be a part of the metal component of the fixed carrier 51. In other embodiments, the magnetic component 59 can also be fixed to the fixed carrier 51 by means of bonding or welding. For example, the magnetic component 59 can be fixed to the surface of the top plate 511 of the fixed carrier 51 facing the inner space of the fixed carrier 51, or it can be embedded in the fixed carrier 51. The magnetic component 59 can be made of magnetic material, that is, a material that can generate magnetic attraction with a magnet or other magnetic components, such as ferromagnetic material.

[0489] FIG56 is a schematic diagram of a partial structure of the circuit board assembly 56 shown in FIG52 in one embodiment.

[0490] 56 , the motor circuit board 561 includes a mounting portion 5611 , a connecting portion 5612 , and a pin end portion 5613 . The connecting portion 5612 is connected between the mounting portion 5611 and the pin end portion 5613 .

[0491] For example, the mounting portion 5611 can be substantially flat. The connecting portion 5612 can be substantially bent. The pin end portion 5613 can also be substantially flat. For example, the surface of the pin end portion 5613 can be perpendicular or substantially perpendicular to the surface of the mounting portion 5611.

[0492] In other embodiments, the shapes of the mounting portion 5611 , the connecting portion 5612 , and the pin end portion 5613 of the motor circuit board 561 are not specifically limited.

[0493] Exemplarily, the mounting portion 5611 includes a first surface 5614 and a second surface 5615 arranged along the third direction Z.

[0494] Fig. 57 is a partial structural diagram of an embodiment of the anti-shake motor 50 shown in Fig. 51. Fig. 58 is a partial structural diagram of the anti-shake motor 50 shown in Fig. 57 at another angle.

[0495] 57 and 58 , and in conjunction with FIG52 and FIG56 , the drive coil 53 is fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. For example, the drive coil 53 may be fixed to the mounting portion 5611 of the motor circuit board 561.

[0496] In one embodiment, the first drive coil 531 is fixed to the first surface 5614 of the mounting portion 5611 and electrically connected to the motor circuit board 561. The second drive coil 532, the third drive coil 533, and the fourth drive coil 534 are fixed to the second surface 5615 of the mounting portion 5611 and electrically connected to the motor circuit board 561. It is understood that the first drive coil 531 and the second drive coil 532 can be arranged along the third direction Z. The first drive coil 531 and the third drive coil 533 can be arranged along the third direction Z. The first drive coil 531 and the fourth drive coil 534 can be arranged along the third direction Z. In addition, the fourth drive coil 534 and the second drive coil 532 can be arranged on the same layer. In other embodiments, the arrangement of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 is not specifically limited. For example, if the space on the first surface 5614 of the mounting portion 5611 allows, the third driving coil 533 and the fourth driving coil 534 may also be fixed to the first surface 5614 of the mounting portion 5611 .

[0497] For example, the number of the first driving coils 531 is three. The three first driving coils 531 may be arranged along the first direction X.

[0498] Exemplarily, there are multiple third drive coils 533. Multiple third drive coils 533 are located on different sides of the second drive coil 532. For example, the number of second drive coils 532 is one. The number of third drive coils 533 is two. The two third drive coils 533 can be located on both sides of the second drive coil 532 in the length direction, that is, the second drive coil 532 is located between the two third drive coils 533. It can be understood that the arrangement of the third drive coil 533 and the second drive coil 532 in this embodiment can also be applied to the arrangement of the first sub-drive coil 151 and the second sub-drive coil 152 of the anti-shake motor 10 mentioned above. The details will not be repeated here.

[0499] For example, the fourth drive coil 534 can be located around the second drive coil 532. In one embodiment, the fourth drive coil 534, the third drive coil 533, and the second drive coil 532 can be arranged along the first direction X. For example, there is one fourth drive coil 534. There is one fourth drive coil 534. The fourth drive coil 534 can be located on a side of a third drive coil 533 away from the second drive coil 532. In other embodiments, the number, size, and position of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 are not specifically limited in this application.

[0500] As shown in Figures 57 and 58 , the driver chip 562 is fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. For example, the driver chip 562 can be fixed to the first surface 5614 of the mounting portion 5611 of the motor circuit board 561. In other embodiments, the location of the driver chip 562 is not specifically limited. For example, if the board space on the second surface 5615 of the mounting portion 5611 allows, the driver chip 562 can also be fixed to the second surface 5615 of the mounting portion 5611.

[0501] It is understood that the drive coil 53 is electrically connected to the drive chip 562 via the motor circuit board 561. The drive chip 562 can control the current of the drive coil 53 (eg, whether current is flowing or the magnitude of the current when it is flowing).

[0502] For example, the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 can all be electrically connected to the drive chip 562 via the motor circuit board 561. The drive chip 562 can control the current conditions of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 (for example, whether current is flowing or the magnitude of the current when it is energized).

[0503] Fig. 59 is a second schematic diagram of a partial structure of an embodiment of the anti-shake motor 50 shown in Fig. 51. Fig. 60 is a schematic diagram of the structure of a portion of the anti-shake motor 50 shown in Fig. 59 at another angle.

[0504] 59 and 60 , and in conjunction with FIG57 and 58 , the motor circuit board 561 is fixed to the fixed carrier 51 . At this point, the driving coil 53 is fixed to the fixed carrier 51 via the motor circuit board 561 .

[0505] For example, the first surface 5614 of the mounting portion 5611 of the motor circuit board 561 is fixed to a side of the top plate 511 of the fixed carrier 51, away from the inner space of the fixed carrier 51. The pin end 5613 of the motor circuit board 561 is fixed to a side of the second side plate 513 of the fixed carrier 51, away from the inner space of the fixed carrier 51. Thus, the motor circuit board 561 extends from the top plate 511 of the fixed carrier 51 to the second side plate 513 of the fixed carrier 51. It will be appreciated that the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 are located on a side of the top plate 511 of the fixed carrier 51, away from the inner space of the fixed carrier 51. The second drive coil 532, the third drive coil 533, and the fourth drive coil 534 can all be located outside the fixed carrier 51. Furthermore, the driver chip 562 (see FIG. 58 ) can be located between the motor circuit board 561 and the top plate 511 of the fixed carrier 51. The motor circuit board 561 and the top plate 511 of the fixed carrier 51 can also be used to protect the driving chip 562 (see FIG. 58 ).

[0506] Referring to FIG. 60 , and in conjunction with FIG. 55 and FIG. 58 , at least a portion of the first drive coil 531 is located within the mounting hole 5111 of the fixed carrier 51 and is exposed relative to the inner space of the fixed carrier 51. It is understood that when there are multiple first drive coils 531 and multiple mounting holes 5111, the multiple first drive coils 531 are disposed in a one-to-one correspondence within the multiple mounting holes 5111. For example, when there are three first drive coils 531 and three mounting holes 5111, the three first drive coils 531 are disposed in a one-to-one correspondence within the three mounting holes 5111. Thus, in the Z-axis direction, the first drive coil 531 and the fixed carrier 51 have an overlapping area, thereby compressing the dimension in the Z-axis direction.

[0507] For example, when there are three first drive coils 531, two of the first drive coils 531 are located on one side of the magnetic member 59, and the other first drive coil 531 is located on the other side of the magnetic member 59. In this way, the installation positions of the three first drive coils 531 can be prevented from significantly affecting the installation position of the magnetic member 59, thereby allowing the magnetic member 59 to be positioned as close to the center of the fixed carrier 51 as possible.

[0508] Referring to FIG. 60 , in conjunction with FIG. 55 and FIG. 58 , the fixed carrier 51 illustratively includes a plurality of first stoppers 516 a, which are used to position the first drive coil 531 to improve the connection stability between the first drive coil 531 and the fixed carrier 51. It will be appreciated that FIG. 55 and FIG. 60 only schematically illustrate one first stopper 516 a.

[0509] Referring to FIG. 59 , and in conjunction with FIG. 53 , FIG. 54 , and FIG. 57 , the fixed carrier 51 illustratively includes a plurality of second stoppers 516 b. These second stoppers 516 b may pass through the motor circuit board 561 and serve to position the second drive coil 532 , the third drive coil 533 , and the fourth drive coil 534 , thereby improving the connection stability between the second drive coil 532 , the third drive coil 533 , and the fourth drive coil 534 and the fixed carrier 51 . It will be appreciated that FIG. 53 , FIG. 54 , and FIG. 59 only schematically illustrate one second stopper 516 b.

[0510] FIG61 is an enlarged schematic diagram of the first bracket 521 shown in FIG52 in one embodiment.

[0511] As shown in Figure 61, the first bracket 521 includes a bottom plate 5211, a first protrusion 5212, and a second protrusion 5213. The first protrusion 5212 and the second protrusion 5213 are protruded from the same side of the bottom plate 5211. The bottom plate 5211, the first protrusion 5212, and the second protrusion 5213 enclose an inner space of the first bracket 521.

[0512] Illustratively, the bottom plate 5211 is provided with a first mounting slot 5214. The opening of the first mounting slot 5214 is located in the inner space of the first bracket 521. In one embodiment, there are two first mounting slots 5214. In other embodiments, the number, shape, and size of the first mounting slots 5214 are not specifically limited.

[0513] For example, the base plate 5211 further includes a first groove 5215. The opening of the first groove 5215 is located in the inner space of the first bracket 521. The first groove 5215 may be spaced apart from the first mounting groove 5214. In one embodiment, there are multiple first grooves 5215. The multiple first grooves 5215 are spaced apart. For example, there are three first grooves 5215. In other embodiments, the number of first grooves 5215 is not specifically limited.

[0514] For example, the bottom plate 5211 further includes a second mounting groove 5216. The opening of the second mounting groove 5216 is located in the inner space of the first bracket 521. The second mounting groove 5216 can be spaced apart from the first mounting groove 5214 and the first groove 5215. The second mounting groove 5216 can be located between two first mounting grooves 5214.

[0515] Exemplarily, the bottom plate 5211 further has a third mounting groove 5217. The opening of the third mounting groove 5217 is located in the second mounting groove 5216.

[0516] FIG62 is a third partial structural diagram of an embodiment of the anti-shake motor 50 shown in FIG51 .

[0517] As shown in Figure 62, the first driving magnetic member 54 is fixed to the movable carrier 52. In one embodiment, the first driving magnetic member 54 is fixed to the bottom plate 5211 of the first bracket 521. The first driving magnetic member 54 can be located in the inner space of the first bracket 521, that is, between the first protrusion 5212 and the second protrusion 5213.

[0518] For example, the first driving magnetic member 54 can be fixed in the first mounting groove 5214. When there are multiple first driving magnetic members 54 and multiple first mounting grooves 5214, the multiple first driving magnetic members 54 are disposed in a one-to-one correspondence in the multiple first mounting grooves 5214. For example, there are two first driving magnetic members 54 and two first mounting grooves 5214. The two first driving magnetic members 54 are disposed in a one-to-one correspondence in the two first mounting grooves 5214.

[0519] It is understood that the first drive magnetic component 54 may include multiple magnets arranged in the first direction X. The first drive magnetic component 54 can be implemented in a variety of structures. For example, the first drive magnetic component 54 may include at least three magnets. Of the three adjacent magnets, the polarity of two adjacent magnets is opposite. For another example, the first drive magnetic component 54 may adopt a dual-magnet structure, for example, consisting of two magnets with opposite polarity. For another example, the first drive magnetic component 54 may include at least three magnets. Of the three adjacent magnets, the polarization of the two magnets located on the edges is opposite and perpendicular to the arrangement of the three magnets, while the polarization of the magnet located in the middle is directed from one magnet to the other. For another example, the first drive magnetic component 54 may be a Halbach magnet array. For another example, the first drive magnetic component 54 may be arranged in a combination array of multiple Halbach magnets, thereby further compressing the distribution of magnetic flux lines, effectively increasing magnetic thrust, and improving magnetic flux utilization. The structure of the first driving magnetic member 54 can be arranged in a variety of ways. The specific application is not limited thereto. Among them, the polarity direction can be the direction of the north pole (N) toward the south pole (S), or the direction of the south pole (S) toward the north pole (N).

[0520] It is understood that when there is only one first drive magnetic component 54, the structure of the first drive magnetic component 54 can adopt any of the structures described above. When there are multiple first drive magnetic components 54, the first drive magnetic components 54 can adopt the same structure, that is, the first drive magnetic component 54 can adopt any of the structures described above. When there are multiple first drive magnetic components 54, the first drive magnetic components 54 can adopt different structures, that is, different first drive magnetic components 54 can adopt any combination of the structures described above.

[0521] In this embodiment, there are two first drive magnetic members 54. One of the first drive magnetic members 54 comprises three magnets. Of the three adjacent magnets, the polarity directions of two adjacent magnets are opposite. The other first drive magnetic member 54 comprises two magnets, and the polarity directions of the two magnets are opposite.

[0522] As shown in Figure 62, the connecting member 581 is disposed on the movable carrier 52. In one embodiment, the connecting member 581 is disposed in the first groove 5215 of the first bracket 521. When there are multiple connecting members 581 and multiple first grooves 5215, the multiple connecting members 581 are disposed in the multiple first grooves 5215 in a one-to-one correspondence.

[0523] It is understood that when the connecting member 581 is a ball, the connecting member 581 can be connected to the movable carrier 52, that is, the connecting member 581 can move within the first groove 5215. For example, grease can be provided between the connecting member 581 and the first groove 5215 to reduce friction between the connecting member 581 and the movable carrier 52. When the connecting member 581 is a sliding shaft or a protruding structure, the connecting member 581 can be fixed to the movable carrier 52.

[0524] As shown in Figure 62, the magnetic component 582 is fixed to the movable carrier 52. In one embodiment, the magnetic component 582 is fixed in the third mounting groove 5217 of the first bracket 521. When there are multiple magnetic components 582 and multiple third mounting grooves 5217, the multiple magnetic components 582 are arranged in the multiple third mounting grooves 5217 in a one-to-one correspondence. It can be understood that by arranging both the connecting member 581 and the magnetic component 582 in the first bracket 521, that is, the connecting member 581 and the magnetic component 582 are arranged in the same structural member, when the first bracket 521 undergoes relative movement, the relative position of the connecting member 581 and the magnetic component 582 is not likely to change to a large extent.

[0525] Exemplarily, the magnetic member 582 may be disposed as close as possible to the center of the bottom plate 5211 of the first bracket 521 .

[0526] FIG63 is a schematic structural diagram of an embodiment of the second bracket 522 shown in FIG52 at different angles.

[0527] As shown in FIG63 , the second bracket 522 is provided with a fixing slot 5221. For example, there are two fixing slots 5221, which are spaced apart. In other embodiments, the number, size, and shape of the fixing slots 5221 are not specifically limited.

[0528] FIG64 is a fourth partial structural diagram of an embodiment of the anti-shake motor 50 shown in FIG51 .

[0529] 64 , and in conjunction with FIG63 , the second driving magnetic member 55 is fixed to the movable carrier 52 . In one embodiment, the second driving magnetic member 55 is fixed in the fixing slot 5221 of the second bracket 522 .

[0530] Exemplarily, when the number of the first sub-driving magnetic component 551 and the number of the fixed groove 5221 of the second driving magnetic component 55 are both two. The two first sub-driving magnetic components 551 are fixed in the two fixed grooves 5221 in a one-to-one correspondence. When the number of the second sub-driving magnetic component 552 of the second driving magnetic component 55 is one, one second sub-driving magnetic component 552 is fixed in one of the fixed grooves 5221. The second sub-driving magnetic component 552 can be located at the end of one of the first sub-driving magnetic components 551. It is understandable that the second sub-driving magnetic component 552 can be arranged on the same layer as the first sub-driving magnetic component 551. In other embodiments, the position between the second sub-driving magnetic component 552 and the first sub-driving magnetic component 551 is not specifically limited.

[0531] It is understandable that the first sub-drive magnetic component 551 may include multiple magnets, and the multiple magnets are arranged in the second direction Y. The implementation structure of the first sub-drive magnetic component 551 can be various. For example, the first sub-drive magnetic component 551 can adopt a dual magnet structure, for example, composed of two magnets, and the polarity directions of the two magnets are opposite. For another example, the first sub-drive magnetic component 551 may include at least three magnets. Among the three adjacent magnets, the polarity directions of the two adjacent magnets are opposite. For another example, the first sub-drive magnetic component 551 may include at least three magnets. Among the three adjacent magnets, the polarization directions of the two magnets located on the edges are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet located in the middle is directed from one magnet to another magnet. For another example, the first sub-drive magnetic component 551 may be a Halbach magnet array. For another example, the first sub-driving magnetic component 551 can be arranged in a combination array of multiple Halbach magnets, thereby further compressing the distribution of magnetic flux lines, effectively increasing the magnetic thrust, and improving the utilization rate of magnetic flux lines.

[0532] It is understood that when the number of the first sub-driving magnetic component 551 is one, the structure of the first sub-driving magnetic component 551 can adopt any of the structures of the first sub-driving magnetic component 551 described above. When the number of the first sub-driving magnetic component 551 is multiple, the first sub-driving magnetic components 551 can adopt the same structure, that is, the first sub-driving magnetic component 551 can adopt any of the structures of the first sub-driving magnetic component 551 described above. When the number of the first sub-driving magnetic component 551 is multiple, the first sub-driving magnetic components 551 can adopt different structures, that is, different first sub-driving magnetic components 551 can adopt any combination of the structures of the first sub-driving magnetic components 551 described above.

[0533] In this embodiment, there are two first sub-driving magnetic members 551. Both of the first sub-driving magnetic members 551 adopt a dual-magnet structure, for example, consisting of two magnets with opposite polarity directions.

[0534] It is understandable that the second sub-driving magnetic component 552 may include a plurality of magnets arranged in the first direction X. The specific structure of the second sub-driving magnetic component 552 may refer to the specific structure of the first driving magnetic component 54 , and will not be described in detail here.

[0535] FIG65 is a fifth partial structural diagram of an embodiment of the anti-shake motor 50 shown in FIG51 .

[0536] Referring to Figure 65 , and in conjunction with Figures 62 and 64 , the second bracket 522 is fixedly connected to the first protrusion 5212 and the second protrusion 5213 of the first bracket 521, and is disposed opposite and spaced apart from the bottom plate 5211 of the first bracket 521. The first bracket 521 and the second bracket 522 form the movable carrier 52. It will be appreciated that since the movable carrier 52 can be assembled from the first bracket 521 and the second bracket 522, when assembling the movable carrier 52 with other structural components, the first bracket 521 and the second bracket 522 can be assembled separately with the other structural components before the second bracket 522 is fixed to the first bracket 521. This assembly method can reduce the assembly of other structural components with the movable carrier 52.

[0537] Exemplarily, the second bracket 522 may be fixedly connected to the first bump 5212 and the second bump 5213 by bonding.

[0538] Exemplarily, the first bump 5212 , the second bump 5213 , and the second bracket 522 all include metal parts. The metal parts of the first bump 5212 and the second bump 5213 are all welded to the metal part of the second bracket 522 .

[0539] For example, the second bracket 522 and the first and second bumps 5212 and 5213 may also cooperate with each other through positioning posts to improve the connection stability between the second bracket 522 and the first bracket 521 .

[0540] Please refer to FIG. 65 , and in combination with FIG. 62 and FIG. 64 , the first driving magnetic component 54 and the second driving magnetic component 55 can be spaced apart and arranged opposite to each other.

[0541] Fig. 66 is a sixth partial structural diagram of an embodiment of the anti-shake motor 50 shown in Fig. 51. Fig. 67 is a partial cross-sectional view of an embodiment of the anti-shake motor 50 shown in Fig. 66 taken along line GG.

[0542] 66 and 67 , and in conjunction with FIG65 , the movable carrier 52 is movably connected to the fixed carrier 51 . For example, the movable carrier 52 can be movably connected to the fixed carrier 51 via a connecting member 581 .

[0543] For example, when the connecting member 581 is a ball, the connecting member 581 can be arranged in contact with the metal portion of the fixed carrier 51. In this way, the friction between the connecting member 581 and the fixed carrier 51 is small, which is conducive to improving the stable movement of the movable carrier 52 relative to the fixed carrier 51.

[0544] For example, grease is provided between the connector 581 and the first groove 5215. This further reduces friction between the connector 581 and the fixed carrier 51, thereby better implementing the ball super-slip system. Furthermore, the connector 581 is less likely to fall out of the first groove 5215.

[0545] For example, a portion of the top plate 511 of the fixed carrier 51 is located between the bottom plate 5211 of the first bracket 521 and the second bracket 522. A portion of the top plate 511 of the fixed carrier 51 and the bottom plate 5211 of the first bracket 521 may be disposed opposite and spaced apart. A portion of the top plate 511 of the fixed carrier 51 and the second bracket 522 may be disposed opposite and spaced apart.

[0546] For example, the bottom plate 5211 of the first bracket 521 is located in the inner space of the fixed carrier 51. The first protrusion 5212 of the first bracket 521 can pass through the fixed carrier 51 from the inner space and extend to the outer space of the fixed carrier 51. Furthermore, the positional relationship between the second protrusion 5213 of the first bracket 521 (see FIG. 62 ) and the fixed carrier 51 can be referred to in the positional relationship between the first protrusion 5212 of the first bracket 521 and the fixed carrier 51. Details are not further described here.

[0547] As shown in Figures 66 and 67, the magnetic member 582 is positioned opposite the magnetic member 59. A magnetic attraction force is generated between the magnetic member 582 and the magnetic member 59. This magnetic attraction force can cause the movable carrier 52 to approach the fixed carrier 51, thereby maintaining contact between the fixed carrier 51, the connecting member 581, and the movable carrier 52. This allows the movable carrier 52 to stably attract the fixed carrier 51 in the Z-axis direction, providing greater stability when the movable carrier 52 moves relative to the fixed carrier 51.

[0548] It is understandable that the position of the magnetic attraction component 582 can be reasonably set to better avoid and balance the overall magnetic interference of the anti-shake motor 50, that is, to avoid magnetic interference between the magnetic attraction component 582 and the first driving magnetic component 54 (see Figure 65) and the second driving magnetic component 55 (see Figure 64) as much as possible.

[0549] It is understandable that by arranging both the connecting member 581 and the magnetic member 582 on the movable carrier 52, the relative positions of the connecting member 581 and the magnetic member 582 are not likely to change significantly when the movable carrier 52 moves relative to the fixed carrier 51. In particular, when there are multiple connecting members 581 and multiple magnetic members 582, the relative positions of the contact centers of the multiple connecting members 581 and the fixed carrier 51 and the centers of magnetic attraction of the multiple magnetic members 582 are not likely to change. At this time, when the movable carrier 52 moves relative to the fixed carrier 51, the stability of the movable carrier 52 is better, that is, stable pressure and smooth movement between the movable carrier 52 and the fixed carrier 51 are achieved.

[0550] Exemplarily, a plurality of the connecting members 581 are arranged around the magnetic member 192 .

[0551] Fig. 68 is a partial cross-sectional view of the anti-shake motor 50 shown in Fig. 66 taken along line HH. Fig. 69 is a partial exploded view of the anti-shake motor 50 shown in Fig. 51 .

[0552] As shown in Figures 68 and 69, the drive coil 53 is located between the first drive magnetic member 54 and the second drive magnetic member 55. The drive coil 53 faces the first drive magnetic member 54 and the second drive magnetic member 55 to drive the movable carrier 52 to move relative to the fixed carrier 51, thereby achieving optical image stabilization.

[0553] As shown in Figures 68 and 69 , the first drive coil 531 faces the first drive magnetic member 54 to drive the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X. For example, there are two first drive magnetic members 54 and three first drive coils 531 . The two first drive coils 531 face the same first drive magnetic member 54 .

[0554] It can be understood that the first drive coil 531 is arranged facing the first drive magnetic part 54, which means that the winding plane of the first drive coil 531 faces the first drive magnetic part 54. For example, the winding plane of the first drive coil 531 can be arranged parallel to the XY plane. For example, the first drive magnetic part 54 can have at least two opposite polarity directions (as shown by the dotted line with arrows in Figure 69, where Figure 69 schematically shows a first drive magnetic part 54 including three polarity directions, wherein two adjacent polarity directions are opposite. Another first drive magnetic part 54 includes two opposite polarity directions). The polarity direction of the first drive magnetic part 54 can be arranged perpendicular to the winding plane of the first drive coil 531. Among them, the coils in the two sections of each first drive coil 531 can be respectively arranged corresponding to the two polarity directions of the first drive magnetic part 54, and the current in the coils in the two sections flows in opposite directions. The side of the first drive magnetic member 54 facing the first drive coil 531 includes a south pole (S) and a north pole (N), and the side of the first drive magnetic member 54 facing away from the first drive coil 531 correspondingly includes a north pole (N) and a south pole (S). It will be understood that because the polarity of the side of the first drive magnetic member 54 facing away from the first drive coil 531 is obscured, FIG. 69 only schematically illustrates the polarity of the side of the first drive magnetic member 54 facing the first drive coil 531.

[0555] It can be understood that since at least part of the first drive coil 531 is located in the mounting hole 5111 of the fixed carrier 51, the fixed carrier 51 no longer separates the first drive coil 531 and the first drive magnetic component 54, so that the first drive coil 531 is arranged as close to the first drive magnetic component 54 as possible.

[0556] For example, the anti-shake motor 50 may also include a first position sensor (not shown). The first position sensor (not shown) may be fixed to and electrically connected to the motor circuit board 561. The first position sensor (not shown) is used to detect the displacement change of the movable carrier 52 relative to the fixed carrier 51 along the first direction X.

[0557] FIG70 is a partial cross-sectional view of an embodiment of the anti-shake motor 50 shown in FIG66 at line II.

[0558] Referring to FIG. 70 , and in conjunction with FIG. 68 and FIG. 69 , the second drive coil 532 faces the first sub-drive magnetic member 551 to drive the movable carrier 52 to move relative to the fixed carrier 51 in the second direction Y. For example, there is one second drive coil 532 and two first sub-drive magnetic members 551 . Furthermore, one second drive coil 532 faces both first sub-drive magnetic members 551 .

[0559] It can be understood that the second drive coil 532 is arranged facing the first sub-drive magnetic part 551, which means that the winding plane of the second drive coil 532 faces the first sub-drive magnetic part 551. For example, the winding plane of the second drive coil 532 can be arranged parallel to the XY plane. Exemplarily, each first sub-drive magnetic part 551 can include at least two polarity directions in opposite directions (as shown by the dotted lines with arrows in Figure 69), and the polarity direction of the first sub-drive magnetic part 551 can be arranged perpendicular to the winding plane of the second drive coil 532. Among them, the coils in the two sections of the second drive coil 532 can be respectively arranged to correspond to the two polarity directions of the first sub-drive magnetic part 551, and the currents in the coils in the two sections flow in opposite directions. Exemplarily, the middle magnet of one of the first sub-drive magnetic parts 551 corresponds to the coils in one section of the two second drive coils 532 at the same time. In addition, the side of the first sub-driving magnetic member 551 facing the second driving coil 532 includes a north pole (N) and a south pole (S), and the side of the first sub-driving magnetic member 551 facing away from the second driving coil 532 correspondingly includes a south pole (S) and a north pole (N). It will be understood that because the polarity of the side of the first sub-driving magnetic member 551 facing the second driving coil 532 is blocked, Figure 69 only schematically shows the polarity of the side of the first sub-driving magnetic member 551 facing the second driving coil 532.

[0560] For example, the anti-shake motor 50 may also include a second position sensor (not shown). The second position sensor (not shown) may be fixed to and electrically connected to the motor circuit board 561. The second position sensor (not shown) is used to detect the displacement change of the movable carrier 52 relative to the fixed carrier 51 along the second direction Y.

[0561] As shown in Figures 68 and 69, the third drive coil 533 faces the first sub-drive magnetic part 551 of the second drive magnetic part 55 to drive the movable carrier 52 to rotate relative to the fixed carrier 51. Exemplarily, there are two third drive coils 533. The two third drive coils 533 are arranged one-to-one facing the two first sub-drive magnetic parts 551. Among them, the arrangement method of the third drive coil 533 and the first sub-drive magnetic part 551 can refer to the arrangement method of the second drive coil 532 and the first sub-drive magnetic part 551. The specific details will not be repeated here.

[0562] It will be appreciated that by connecting the two third drive coils 533 in series, the currents flowing through the two third drive coils 533 flow in opposite directions. Consequently, when the two third drive coils 533 are energized, they experience opposite forces. For example, when the first third drive coil 533 experiences a force in the positive direction of the Y-axis, the second third drive coil 533 experiences a force in the negative direction of the Y-axis. At this point, the torque exerted by the two third drive coils 533 on the movable carrier 52 causes the movable carrier 52 to rotate relative to the fixed carrier 51.

[0563] It is understood that by providing the third drive coil 533 and the first sub-drive magnetic component 551, rotation compensation about the Z-axis direction is achieved. For example, when the movable carrier 52 rotates clockwise relative to the fixed carrier 51, the direction and magnitude of the current in the second sub-drive coil of the second drive coil 532 can be controlled to obtain a compensating driving force that rotates the movable carrier 52 counterclockwise relative to the fixed carrier 51, thereby achieving rotation compensation of the movable carrier 52 about the Z-axis direction. In addition, because the third drive coil 533 and the second drive coil 532 can share the same first sub-drive magnetic component 551, the structure of the anti-shake motor 50 is simplified, which facilitates the miniaturization of the anti-shake motor 50.

[0564] It is understandable that the third driving coil 533 and the second driving coil 532 can share the first sub-driving magnetic component 551. Therefore, the structure of the anti-shake motor 50 of this embodiment is relatively simple.

[0565] It is understood that the angular change in the rotation of the movable carrier 52 relative to the fixed carrier 51 can also be detected by position sensors. For example, by providing a third position sensor and a fourth position sensor, both the third position sensor and the fourth position sensor can be fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. The third position sensor can be used to detect a first displacement change of the movable carrier 52 relative to the fixed carrier 51 along the first direction X. The fourth position sensor can be used to detect a second displacement change of the movable carrier 52 relative to the fixed carrier 51 along the first direction X. The third and fourth position sensors can cooperate with each other to detect the angular change in the rotation of the movable carrier 12 relative to the fixed carrier 11. For another example, by providing a third position sensor and cooperating with the first position sensor, the angular change in the rotation of the movable carrier 12 relative to the fixed carrier 11 can be detected. For another example, by providing a third position sensor and cooperating with the second position sensor, the angular change in the rotation of the movable carrier 12 relative to the fixed carrier 11 can be detected.

[0566] As shown in Figures 68 and 69, the fourth drive coil 534 faces the second sub-drive magnetic member 552 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. For example, there is one fourth drive coil 534. There is one second sub-drive magnetic member 552. The arrangement of the fourth drive coil 534 and the second sub-drive magnetic member 552 can refer to the arrangement of the first drive coil 531 and the first drive magnetic member 54. The details will not be repeated here.

[0567] It is understood that, while satisfying the driving force requirements for the movable carrier 52 to move in the second direction Y, and if the space between the second bracket 522 and the fixed carrier 51 permits, a fourth driving coil 534 can be additionally provided at the layer where the second driving coil 532 is located, and a second sub-driving magnetic component 552 can be additionally provided at the layer where the first sub-driving magnetic component 551 is located, and the fourth driving coil 534 and the second sub-driving magnetic component 552 can be utilized to drive the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X. In this case, the fourth driving coil 534 and the second sub-driving magnetic component 552 can cooperate with the first driving coil 531 and the first driving magnetic component 54, thereby significantly increasing the driving force for the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X, which is beneficial for increasing the travel of the movable carrier 52 relative to the fixed carrier 51 in the first direction X.

[0568] FIG71 is an enlarged schematic diagram of an embodiment of the movable circuit board 57 shown in FIG52.

[0569] As shown in FIG71 , the movable circuit board 57 includes a first fixing portion 571 , an elastic portion 572 , and a second fixing portion 573 . The elastic portion 572 is connected between the first fixing portion 571 and the second fixing portion 573 .

[0570] Exemplarily, the elastic portion 572 is in a spiral, broken line or curved shape. In this way, the length of the elastic portion 572 can be increased, thereby greatly reducing the elastic coefficient of the elastic portion 572.

[0571] Exemplarily, the length of the elastic portion 572 is greater than half of the circumference of the edge of the first fixing portion 571 .

[0572] Exemplarily, the elastic portion 572 surrounds at least half of the edge of the first fixing portion 571 , or the elastic portion 572 surrounds the edge of the first fixing portion 571 in multiple circles.

[0573] For example, the elastic coefficient of the movable circuit board 57 in the length direction is K Y , K Y The size of is in the range of 20 to 40. For example, the elastic coefficient of the movable circuit board 57 in the length direction is KY It can be 30.

[0574] And / or, the elastic coefficient of the movable circuit board 57 in the width direction is K X , K X The size is in the range of 70 to 110. For example, the elastic coefficient of the movable circuit board 57 in the length direction is K X It can be 93.

[0575] Exemplarily, the movable circuit board 57 further includes a reinforcing portion 574 . The reinforcing portion 574 is fixed to the first fixing portion 571 . The reinforcing portion 574 may be a steel plate or other metal plate. In one embodiment, the reinforcing portion 574 may be fixed to the first fixing portion 571 using adhesive. In other embodiments, the movable circuit board 57 may not include the reinforcing portion 574 .

[0576] FIG72 is a seventh partial structural diagram of an embodiment of the anti-shake motor 50 shown in FIG51 .

[0577] 72 , in combination with FIG71 , the movable carrier 52 is fixed to the first fixing portion 571 of the movable circuit board 57 . In one embodiment, the movable carrier 52 may have no connection with either the elastic portion 572 or the second fixing portion 573 of the movable circuit board 57 .

[0578] Exemplarily, the bottom plate 5211 of the first bracket 521 of the movable carrier 52 is fixed to the reinforcing portion 574 , that is, the movable carrier 52 is fixed to the first fixing portion 571 via the reinforcing portion 574 .

[0579] In one embodiment, the movable carrier 52 and the first fixing portion 571 both include metal parts, and the metal part of the movable carrier 52 can be welded to the metal part of the first fixing portion 571 .

[0580] It is understood that when the movable carrier 52 moves in the first direction X, the elastic portion 572 of the movable circuit board 57 is deformed in the first direction X. The first fixing portion 571 of the movable circuit board 57 can follow the movable carrier 52 in moving in the first direction X. When the movable carrier 52 moves in the second direction Y, the elastic portion 572 of the movable circuit board 57 is deformed in the second direction Y. The first fixing portion 571 of the movable circuit board 57 can follow the movable carrier 52 in moving in the second direction Y.

[0581] Please refer to FIG. 72 , and in combination with FIG. 69 and FIG. 71 , in one embodiment, the elastic coefficient of the movable circuit board 5718 in the width direction is K X , which is less than the elastic coefficient K of the movable circuit board 5718 in the length direction Y , that is, K of the active circuit board 5718 YLess than K X It is understandable that due to the K of the active circuit board 57 Y Less than K X , so that the travel of the movable carrier 52 relative to the fixed carrier 51 along the second direction Y is limited to be smaller than the travel of the movable carrier 52 relative to the fixed carrier 51 along the first direction X. In this case, the embodiment can better match the K of the movable circuit board 57 by setting the driving force generated by the second driving coil 532 and the first sub-driving magnetic member 551 to be smaller than the driving force generated by the first driving coil 531 and the first driving magnetic member 54. Y Less than K X For example, the number of the second driving coils 532 and the first sub-driving magnetic members 551 can be set to be smaller, which is conducive to the miniaturization of the anti-shake motor 50.

[0582] Fig. 73 is a partial structural diagram of an embodiment of the image sensor assembly 101 shown in Fig. 50. Fig. 74 is a partial cross-sectional view of an embodiment of the image sensor assembly 101 shown in Fig. 73 taken along line JJ.

[0583] As shown in Figures 73 and 74 , the image sensor module 20 includes a module circuit board 21, an image sensor 22 (also referred to as a sensor), a filter holder 23, and a filter 24. For details on the structures of the various components of the image sensor module 20, please refer to the structures of the various components of the image sensor module 20 described in the above embodiments (e.g., Figures 31 to 33 ). Details will not be repeated here.

[0584] As shown in Figures 73 and 74 , the image sensor module 20 is fixed to the first fixing portion 571 of the movable circuit board 57. The image sensor module 20 is located on a side of the first fixing portion 571 of the movable circuit board 57 that is away from the reinforcing portion 574. It is understood that the image sensor module 20 may have no connection to either the elastic portion 572 or the second fixing portion 573 of the movable circuit board 57.

[0585] For example, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing portion 571 of the movable circuit board 57. The module circuit board 21 is electrically connected to the movable circuit board 57. In this way, external devices of the camera module 100 can be electrically connected to the image sensor 22 through the movable circuit board 57 and the module circuit board 21.

[0586] Exemplarily, the module circuit board 21 is electrically connected to the first fixing portion 571 of the movable circuit board 57 through a welding process, and then electrically connected to the second fixing portion 573 through the elastic portion 572 of the movable circuit board 57 .

[0587] As shown in Figures 73 and 74 , the image sensor module 20 is illustratively located on the side of the first fixing portion 571 of the movable circuit board 57 that is away from the movable carrier 52. In other words, the image sensor module 20 is located on the side of the first fixing portion 571 of the movable circuit board 57 that is away from the first driving magnetic member 54. At this time, the image sensor module 20 is fixed to the movable carrier 52 via the movable circuit board 57. In an exemplary embodiment, the image sensor module 20 is fixed to the bottom plate 5211 of the first bracket 521 of the movable carrier 52 via the first fixing portion 571 of the movable circuit board 57.

[0588] It is understood that when the movable carrier 52 moves relative to the fixed carrier 51 in the first direction X, the elastic portion 572 of the movable circuit board 57 deforms along the first direction X. The image sensor module 20 and the first fixed portion 571 of the movable circuit board 57 can follow the movement of the movable carrier 52 in the first direction X. When the movable carrier 52 moves relative to the fixed carrier 51 in the second direction Y, the elastic portion 572 of the movable circuit board 57 deforms along the second direction Y. The image sensor module 20 and the first fixed portion 571 of the movable circuit board 57 can follow the movement of the movable carrier 52 in the second direction Y. Therefore, the movable carrier 52 can control the movement of the image sensor module 20 along a plane perpendicular to the third direction Z (i.e., the XY plane) via the movable circuit board 57. When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the image sensor module 20 in the XY plane can be controlled to offset the vibrating stroke of the camera module 100 in the XY plane, so as to avoid or reduce the position offset of the camera module 100 caused by the vibration, thereby realizing optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0589] In addition, when the movable carrier 52 is driven to rotate clockwise relative to the fixed carrier 51, the movable carrier 52 drives the image sensor module 20 to rotate clockwise via the elastic portion 572 of the movable circuit board 57. In this embodiment, by controlling the direction and magnitude of the current in the third drive coil 533 of the drive coil 53 to obtain a compensating driving force for the movable carrier 52 to rotate counterclockwise relative to the fixed carrier 51, rotation compensation of the movable carrier 52 about the Z-axis is achieved. At this time, the image sensor module 20 also rotates about the Z-axis to compensate for the jitter caused by the camera module 100 rotating about the Z-axis, thereby avoiding or reducing the position offset of the camera module 100 caused by jitter, thereby achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0590] As shown in FIG74 , the first bracket 521 further includes a fixing protrusion 5219. The fixing protrusion 5219 is protruding from the bottom plate 5211 and is located on the side of the bottom plate 5211 facing the image sensor module 20. The fixing protrusion 5219 can pass through the movable circuit board 57 and be fixedly connected to the image sensor module 20. For example, the fixing protrusion 5219 passes through the gap between the first fixing portion 571 and the elastic portion 572 of the movable circuit board 57 and is fixedly connected to the image sensor module 20.

[0591] It will be appreciated that, by providing a fixing protrusion 5219 protruding from the bottom plate 5211 of the first bracket 521, the fixing protrusion 5219 passes through the movable circuit board 57 and is directly fixedly connected to the image sensor module 20. Thus, compared to a solution in which the image sensor module 20 is fixedly connected to the first bracket 521 via the movable circuit board 57, in this embodiment, on the one hand, the assembly tolerance chain between the image sensor module 20 and the first bracket 521 is shorter, the assembly tolerance between the image sensor module 20 and the first bracket 521 is smaller, and the image sensor module 20 and the bottom plate 5211 of the first bracket 521 can be largely coplanar. On the other hand, when the movable carrier 52 moves in the XY plane, the movable carrier 52 can directly drive the movement of the image sensor module 20, and the movement of the image sensor module 20 is less affected by the movable circuit board 57.

[0592] As shown in Figure 74, the fixed carrier 51 is fixed to the second fixing portion 573 of the movable circuit board 57. The fixed carrier 51 can be disconnected from the first fixing portion 571 and the elastic portion 572 of the movable circuit board 57. This improves the integrity of the anti-shake motor 10 and the movable circuit board 57.

[0593] 74 , the motor circuit board 561 is electrically connected to the movable circuit board 57. Thus, the driver chip 562 (see FIG. 58 ) can be electrically connected to the movable circuit board 57 through the motor circuit board 561 and electrically connected to the outside of the image sensor assembly 101 through the movable circuit board 57.

[0594] For example, the pin end 5613 of the motor circuit board 561 is electrically connected to the second fixing portion 573 of the movable circuit board 57. Thus, the driver chip 562 (see FIG. 58 ) can be electrically connected to the second fixing portion 573 of the movable circuit board 57 via the mounting portion 5611, the connecting portion 5612, and the pin end 5613 of the motor circuit board 561, and can be electrically connected to the exterior of the image sensor assembly 101 via the second fixing portion 573 of the movable circuit board 57. In other words, the drive coil 53 can be electrically connected to the second fixing portion 573 of the movable circuit board 57 via the driver chip 562 and the motor circuit board 561. It will be appreciated that in this embodiment, where the driver chip 562 (see FIG. 58 ) is electrically connected to the exterior of the image sensor assembly 101, the motor circuit board 561 does not need to be electrically connected to the first fixing portion 571 and the elastic portion 572 of the movable circuit board 57. In this embodiment, the driver chip 562 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57. This approach of electrically connecting the driver chip 562 to the exterior of the image sensor assembly 101 is simpler and easier to mass-produce. In other embodiments, the electrical connection method and electrical connection position between the motor circuit board 561 and the movable circuit board 57 are not specifically limited.

[0595] In other embodiments, the driver chip 562 may be directly disposed on the second fixing portion 573 of the movable circuit board 57. The drive coil 53 may be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 via the motor circuit board 561, and electrically connected to the driver chip 562 via the second fixing portion 573 of the movable circuit board 57. In other embodiments, if the anti-shake motor 50 does not include the driver chip 562, the drive coil 53 may be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 via the motor circuit board 561, and electrically connected to the outside of the anti-shake motor 50 via the second fixing portion 573 of the movable circuit board 57.

[0596] FIG75 is a partial cross-sectional view of an embodiment of the image sensor assembly 101 shown in FIG50 at line KK.

[0597] As shown in Figure 75, the upper housing 30 and the lower housing 40 are respectively fixed to either side of the fixed carrier 51. The upper housing 30, the lower housing 40, and the fixed carrier 51 are assembled and cooperated to jointly enclose the movable carrier 52 and the internal structure of the anti-shake motor 50 (e.g., the drive coil 53, the first drive magnetic member 54, the second drive magnetic member 55, etc.). The upper housing 30, the lower housing 40 cooperate with the fixed carrier 51 to jointly encapsulate and protect the internal structure of the anti-shake motor 50. It can be understood that the mutual cooperation between the upper housing 30, the lower housing 40, and the fixed carrier 51 can make the anti-shake motor 50 more aesthetically pleasing and more integrated.

[0598] For example, the lower housing 40 is further provided with a light-transmitting hole 40a. The lower housing 40 can also be fixed to the second fixing portion 573 of the movable circuit board 57. This, on the one hand, improves the stability of the lower housing 40, thereby enhancing the integrity of the image sensor assembly 101. On the other hand, the lower housing 40 can also be used to cover the first fixing portion 571, the elastic portion 572, and the image sensor module 20 of the movable circuit board 57. In addition, the image sensor 22 of the image sensor module 20 is arranged opposite the light-transmitting hole 40a of the lower housing 40. In this way, external light from the image sensor assembly 101 can pass through the light-transmitting hole 40a of the lower housing 40 and be transmitted to the image sensor 22 through the filter 24.

[0599] For example, the light-transmitting hole 40 a of the lower housing 40 may be opposite to the third side surface 1023 (see FIG. 2 ) of the first light path conversion element 102 (see FIG. 2 ).

[0600] The above description specifically introduces the architecture of another image sensor assembly 101 in conjunction with the relevant drawings.

[0601] As shown in Figures 68 to 70, this embodiment provides a driving structure of a magnetic coil similar to a "sandwich". Specifically, the driving coil 53 is fixed to the fixed carrier 51, the first driving magnetic part 54 and the second driving magnetic part 55 are both fixed to the movable carrier 52, and the driving coil 53 is located between the first driving magnetic part 54 and the second driving magnetic part 55. It can be understood that compared with the solution in which the first driving magnetic part 54 and the second driving magnetic part 55 are laid flat on the XY plane, the first driving magnetic part 54, the driving coil 53 and the second driving magnetic part 55 of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction, compressing the dimensions in the XY-axis direction, and greatly improving the space utilization in the Z-axis direction.

[0602] It can be understood that the first drive coil 531 faces the first drive magnetic part 54 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. The second drive coil 532 faces the first sub-drive magnetic part 551 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the second direction Y. In this way, the movable carrier 52 can move relative to the fixed carrier 51 along a plane perpendicular to the third direction Z (that is, the XY plane). When the camera module 100 collects ambient light, if the electronic device 1000 vibrates in the XY plane due to external force, the movement of the image sensor module on the XY plane can be controlled to offset the jitter stroke of the camera module 100 in the XY plane, so as to avoid or reduce the position offset of the camera module 100 caused by the jitter, thereby realizing optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0603] In addition, since the first driving magnetic component 54 and the second driving magnetic component 55 can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane of the first driving magnetic component 54 and the second driving magnetic component 55 will not affect each other, which is conducive to maximizing the number of the first driving magnetic component 54 and the second driving magnetic component 55.

[0604] It is understood that since the drive coil 53 is fixed to the fixed carrier 51, and the first drive magnetic member 54 and the second drive magnetic member 55 are both fixed to the movable carrier 52, the anti-shake motor 50 of this embodiment is a moving magnet motor. As a result, the electrical connection method of the drive coil 53 of this embodiment is simpler than that of a moving coil motor.

[0605] It can be understood that in the "pyramid" stacked anti-shake motor architecture of the present application, the second drive coil 532 is arranged in the middle layer of the tower and a set of symmetrical series reverse coils (third drive coil 533) is added to achieve rotation compensation to solve the image rotation problem.

[0606] It can be understood that since the drive coil 53 is located between the first drive magnetic component 54 and the second drive magnetic component 55, the first drive magnetic component 54 and the second drive magnetic component 55 are far apart, which is beneficial to reduce the crosstalk of the magnetic flux lines of the first drive magnetic component 54 and the second drive magnetic component 55, and ensure the utilization rate of the magnetic flux lines of the first drive magnetic component 54 and the second drive magnetic component 55.

[0607] FIG76 is a schematic diagram showing the arrangement of the second drive coil 532 and the third drive coil 533 shown in FIG52 in another embodiment.

[0608] As shown in Figure 76, there are multiple third drive coils 533. The multiple third drive coils 533 are located on the same side of the second drive coil 532. In one embodiment, the multiple third drive coils 533 are located on the same side of the second drive coil 532 in the width direction.

[0609] For example, there is one second driving coil 532. There are two third driving coils 533. The two third driving coils 533 are located on the same side of the second driving coil 532 in the width direction (ie, the Y-axis direction).

[0610] Exemplarily, the two third driving coils 533 are arranged in sequence along the first direction X.

[0611] In other embodiments, the arrangement of the third driving coil 533 and the second driving coil 532 is not specifically limited in this application.

[0612] As shown in FIG. 76 , the plurality of third driving coils 533 face the first sub-driving magnetic member 551 to drive the movable carrier 52 to rotate relative to the fixed carrier 51 .

[0613] Exemplarily, the first sub-drive magnetic member 551 includes at least three polarity directions in opposite directions (shown by the dotted lines with arrows in FIG. 76 ), and two adjacent polarity directions are opposite. The polarity direction of the first sub-drive magnetic member 551 can be set perpendicular to the winding plane of the second drive coil 532. Among them, the coils of the two sections of a third drive coil 533 can respectively correspond to the first polarity direction and the second polarity direction of the first sub-drive magnetic member 551. The coils of the two sections of another third drive coil 533 can respectively correspond to the second polarity direction and the third polarity direction of the first sub-drive magnetic member 551. It can be understood that the middle magnet of the first sub-drive magnetic member 551 can be set opposite to the two third drive coils 533 at the same time. Therefore, the two third drive coils 533 can share the middle magnet of the first sub-drive magnetic member 551.

[0614] It is understood that Figure 76 only schematically illustrates three polarity directions of the first sub-driving magnetic member 551. In other embodiments, the polarity direction in the middle of the first sub-driving magnetic member 551 and the polarity directions on both sides can be swapped.

[0615] It is understandable that the anti-shake motor 50 of this embodiment can also be applied to the aforementioned image sensor assembly 101. The details will not be described in detail here.

[0616] It can be understood that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0617] It is understood that all the above drawings are illustrative illustrations of this application and do not represent the actual size of the product. The dimensional ratio relationship between the components in the drawings does not serve as a limitation on the actual product of this application. The above are only some of the embodiments and implementation methods of this application. The scope of protection of this application is not limited to this. Any person skilled in the art who is familiar with the technical scope disclosed in this application can easily think of changes or replacements, which should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
