Description

Technical Field

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

[0002] With the widespread adoption and development of smartphones, mobile phone photography has become a common way for people to take pictures, and phones with optical image stabilization (OIS) are increasingly favored by users. Traditional camera modules include an image sensor, an image stabilization motor, and an image sensor. The image sensor OIS motor achieves image stabilization by controlling the movement of the image sensor. Traditional image sensor OIS motors generally achieve driving force through the cooperation of coils and magnets. However, because the magnetic field lines of traditional magnets are only effectively utilized on one side by the driving coil, the Z-axis magnetic field utilization rate is low, resulting in a relatively small driving stroke for traditional image sensor OIS motors. Summary of the Invention

[0003] This application provides a stabilization motor, an image sensor assembly, a camera module, and an electronic device, aiming to obtain a stabilization motor that can improve the utilization of magnetic field lines and achieve a larger rated stroke.

[0004] In one aspect, a stabilization motor is provided. The stabilization motor includes a fixed carrier, a movable carrier, a driving magnetic component, a first driving coil, and a second driving coil, wherein the movable carrier is used to fix the image sensor module;

[0005] The driving magnetic component is fixed to the fixed carrier, and both the first driving coil and the second driving coil are fixed to the movable carrier. The driving magnetic component is located between the first driving coil and the second driving coil.

[0006] Both the first and second drive coils face the driving magnetic component to drive the movable carrier to move relative to the fixed carrier.

[0007] Understandably, this application provides a driving architecture for a magnetic coil similar to a "sandwich". The driving magnetic component is fixed to a fixed carrier, and both the first and second driving coils are fixed to a movable carrier, with the driving magnetic component located between the first and second driving coils. Understandably, on the one hand, the magnetic field lines on both sides of the driving magnetic component can be fully utilized by the first and second driving coils. The high magnetic field utilization of the driving magnetic component is beneficial for increasing the driving stroke of the image stabilization motor. On the other hand, compared to the scheme where the first and second driving coils are laid flat in the XY plane, the first driving coil, driving magnetic component, and second driving coil of this application are arranged sequentially 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 significantly improve the space utilization in the Z-axis direction, and the increased utilization of magnetic field lines leads to increased thrust, making it possible to apply image stabilization to telephoto modules with more compact space and greater required rated stroke.

[0008] In addition, since the first driving magnetic component and the second driving magnetic component can be arranged along the Z-axis, the number of magnets arranged in the XY plane will not affect each other, which is beneficial to maximizing the number of the first driving magnetic component and the second driving magnetic component.

[0009] In one possible implementation, the fixed carrier includes a magnetic shielding sheet, which includes a first side and a second side facing away from each other, the first side facing the first driving coil and the second side facing the second driving coil; the driving magnetic component includes a first driving magnetic component and a second driving magnetic component, the first driving magnetic component being fixed to the first side and the second driving magnetic component being fixed to the second side.

[0010] The first driving coil faces the first driving magnetic component to drive the movable carrier to move relative to the fixed carrier in the first direction;

[0011] The second drive coil includes a first sub-drive coil facing the second drive magnetic component, so as to drive the movable carrier to move relative to the fixed carrier in a second direction, which is different from the first direction.

[0012] Understandably, the first driving coil faces the first driving magnetic component to drive the movable carrier to move relative to the fixed carrier along the first direction X. The first sub-driving coil of the second driving magnetic component faces the second driving magnetic component 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 (i.e., the XY plane). When the camera module collects ambient light, if the electronic device experiences shaking in the XY plane due to external forces, the movement of the image sensor module in the XY plane can be controlled to counteract the shaking stroke of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by shaking, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0013] In addition, the first driving magnetic component is fixed to the first surface of the magnetic shielding sheet, and the second driving magnetic component is fixed to the second surface of the magnetic shielding sheet. In this way, the magnetic shielding sheet can effectively isolate the magnetic field lines crosstalk between the first and second driving magnetic components, ensuring the utilization rate of the magnetic field lines of the first and second driving magnetic components.

[0014] In addition, since the first driving magnetic component and the second driving magnetic component can be arranged along the Z-axis, the number of magnets arranged in the XY plane will not affect each other, which is beneficial to maximizing the number of the first driving magnetic component and the second driving magnetic component.

[0015] In one 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 element to drive the movable carrier to rotate relative to the fixed carrier.

[0016] It is understandable that by setting the second sub-drive coil to face the second drive magnetic component, the movable carrier can be driven to rotate relative to the fixed carrier, thereby achieving rotational compensation. For example, when the movable carrier rotates clockwise relative to the fixed carrier, the movable carrier will cause the image sensor module to rotate clockwise. At this time, by controlling the direction and magnitude of the current in the second sub-drive coil of the second drive coil, a compensating driving force is obtained to make the movable carrier rotate counterclockwise relative to the fixed carrier, thereby achieving rotational compensation of the movable carrier around the Z-axis. At this time, the image sensor module also performs rotational compensation around the Z-axis to counteract the jitter stroke caused by the rotation of the camera module around the Z-axis, thereby avoiding or reducing the positional offset of the camera module caused by jitter, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0017] In one possible implementation, there are two second sub-drive coils connected in series, with the current flowing in opposite directions. Thus, when both second sub-drive coils are energized, they experience opposite forces. For example, when the first second sub-drive coil experiences a force in the positive Y-axis direction, the second second sub-drive coil experiences a force in the negative Y-axis direction. The torque exerted by the two second sub-drive coils on the moving carrier allows the moving carrier to rotate relative to the fixed carrier.

[0018] In one possible implementation, the image stabilization motor includes a first position sensor, a second position sensor, and a third position sensor, all of which are fixed to the movable carrier at intervals.

[0019] The first position sensor and the second position sensor are used to individually detect the displacement of the moving 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 moving carrier relative to the fixed carrier;

[0020] And / or, the anti-shake motor includes a third position sensor, the third position sensor being fixed to the movable carrier, the third position sensor being used to detect the displacement of the movable carrier relative to the fixed carrier along the second direction.

[0021] In one possible implementation, the movable carrier is movably connected to the fixed carrier via a rolling element. It is understood that, compared to a scheme where the movable carrier is movably connected to the fixed carrier via a guide bracket, this embodiment offers a simpler connection method and a more streamlined structure, which is beneficial for miniaturizing the anti-shake motor.

[0022] For example, there are three rolling elements, which are distributed in different positions to support the fixed carrier at three points, so as to achieve a stable setting of the anti-shake motor.

[0023] In one possible implementation, the fixed carrier includes a metal component and an insulating component, the metal component being embedded in the insulating component and including an extension that protrudes relative to the insulating component; a rolling component is disposed on the movable carrier and contacts the extension.

[0024] Understandably, since the extension of the fixed carrier is made of metal, the friction between the rolling element and the fixed carrier is small, which helps to improve the stable movement of the moving carrier relative to the fixed carrier.

[0025] In one possible implementation, the moving carrier is provided with a rolling element groove. The rolling element is located within the rolling element groove. This prevents the rolling element from easily detaching from the moving carrier.

[0026] In one possible implementation, grease is provided between the rolling element and the rolling element groove. This further reduces the friction between the rolling element and the stationary carrier, thereby better achieving a super-lubricated rolling element system. Furthermore, the rolling element is less likely to dislodge from the rolling element groove.

[0027] In one possible implementation, the extension is made of a magnetic material, and the movable carrier is provided with a magnetic element, which is arranged opposite to the extension.

[0028] Understandably, the magnetic attracting component and the extension are positioned opposite each other. A magnetic attraction force can be generated between the magnetic attracting component and the extension. This magnetic attraction force causes the movable carrier to tend to move closer to the fixed carrier. In this way, the movable carrier can stably hold the fixed carrier in the Z-axis direction, resulting in better stability of the movable carrier when moving relative to the fixed carrier.

[0029] Understandably, the extension of the fixed carrier can provide a smooth contact surface for the rolling element and also serve as a magnetic attractor for the magnetic element. The extension of the fixed carrier has a "multi-purpose" function.

[0030] Understandably, by placing both the rolling elements and the magnetic attraction elements on the movable carrier, the relative positions of the rolling elements and the magnetic attraction elements 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 attraction elements, the relative positions of the contact centers between the multiple rolling elements and the fixed carrier and the magnetic attraction centers of the multiple magnetic attraction elements are less likely to change. In this case, the movable carrier exhibits better stability when moving relative to the fixed carrier, achieving stable pressing and smooth movement between the movable and fixed carriers.

[0031] In one possible implementation, the movable carrier includes a first support and a second support; the first support includes a base plate, a first protrusion and a second protrusion, the first protrusion and the second protrusion are protruding on the same side of the base plate, and the second support is fixedly connected to the first protrusion and the second protrusion, and is opposite to the base plate and spaced apart.

[0032] The first drive coil is fixed to the base plate, and the second drive coil is fixed to the second bracket.

[0033] Understandably, by configuring the movable carrier to consist of a first support and a second support, when the second support is installed on the first and second protrusions of the first support, the second support and the base plate are opposite to each other and spaced apart, meaning there is installation space between the second support and the base plate. Then, a portion of the fixed carrier is positioned between the base plate of the first support and the second support. Thus, when the driving magnetic component is fixed to the fixed carrier, and both the first and second driving coils are fixed to the movable carrier, the driving magnetic component can be located between the first and second driving coils.

[0034] Understandably, by setting the movable carrier to consist of a first support and a second support, it is beneficial to facilitate the assembly of the movable carrier and the fixed carrier.

[0035] In one possible implementation, the image stabilization motor further includes a movable circuit board, which includes a first fixed part, an elastic part, and a second fixed part, with the elastic part 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.

[0036] It is understandable that when the moving carrier moves along the first direction X, the elastic part of the moving circuit board deforms along the first direction X. The first fixing part of the image sensor module and the moving circuit board can follow the moving carrier to move along the first direction X. When the moving carrier moves relative to the fixed carrier along the second direction Y, the elastic part of the moving circuit board deforms along the second direction Y. The first fixing part of the image sensor module and the moving circuit board can follow the moving carrier to move along the second direction Y. Therefore, the moving 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 moving circuit board. When the camera module collects ambient light, if the electronic device shakes in the XY plane due to external forces, the movement of the image sensor module in the XY plane can be controlled to counteract the shaking stroke of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by shaking, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0037] Furthermore, when the moving carrier rotates clockwise relative to the fixed carrier, the moving carrier drives the image sensor module to rotate clockwise via the elastic part of the moving circuit board. In this embodiment, by controlling the direction and magnitude of the current in the second sub-driving coil of the second driving coil, a compensating driving force is obtained to compensate for the counterclockwise rotation of the moving carrier relative to the fixed carrier, thereby achieving rotational compensation of the moving carrier around the Z-axis. At this time, the image sensor module also undergoes rotational compensation around the Z-axis to counteract the jitter stroke caused by the rotation of the camera module around the Z-axis, thereby avoiding or reducing the positional offset of the camera module caused by jitter, and thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0038] For example, the image sensor module is also electrically connected to a first fixing part of the movable circuit board. The image sensor can be electrically connected to the first fixing part of the movable circuit board via the module circuit board, and electrically connected to the outside of the image sensor assembly via the elastic part and the second fixing part of the movable circuit board.

[0039] In one possible implementation, the elastic part is spiral, zigzag, or curved. This increases the length of the elastic part, thereby significantly reducing its elastic coefficient. The movement stroke of the moving circuit board is less restricted, which facilitates setting a larger anti-shake stroke for the moving carrier. Furthermore, the spiral-shaped, low-K-value elastic part can effectively compress the dimensions in the X and Y axes while maintaining a small size in the Z-axis direction, reducing crosstalk in XY plane motion and optimizing electromagnetic drive performance and power consumption.

[0040] In one possible implementation, the length of the elastic portion is greater than half the perimeter of the edge of the first fixed portion. This increases the length of the elastic portion, thereby significantly reducing its elastic modulus.

[0041] In one possible implementation, the elastic portion surrounds at least half of the edge of the first fixed portion, or the elastic portion surrounds the edge of the first fixed portion in multiple turns. This increases the length of the elastic portion, thereby significantly reducing its elastic modulus.

[0042] In one possible implementation, the elastic modulus 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 modulus of the active circuit board in the width direction is K. X K X The size is in the range of 85 to 100. At this time, the K of the active circuit board... Y Less than K X .

[0043] Understandably, due to the K of the active circuit board Y Less than K X This restricts the travel distance of the movable carrier relative to the fixed carrier in the second direction Y, making it less restrictive than the travel distance of the movable carrier relative to the fixed carrier in the first direction X. In this case, this embodiment can better match the K of the movable circuit board by setting the driving force generated by the first sub-drive coil and the second drive magnetic component to be less than the driving force generated by the first drive coil and the first drive magnetic component. Y Less than K X For example, the number of the first sub-drive coils and the number of the second drive magnetic components can be reduced, which is beneficial for miniaturizing the anti-shake motor.

[0044] In one possible implementation, the movable circuit board further includes a reinforcing portion located within the first fixing portion, and the movable carrier is fixed to the reinforcing portion. It is understood that the reinforcing portion can be a steel plate or other metal plate. The reinforcing portion can improve the overall strength of the first fixing portion.

[0045] In one possible implementation, the first bracket further includes a fixing protrusion that protrudes from the base plate and is located on the 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.

[0046] It is understood that by providing a fixing protrusion on the base plate of the first bracket, and using the fixing protrusion to pass through the movable circuit board, the image sensor module is directly and fixedly connected. In this way, compared to the solution where 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 base plate of the image sensor module and the first bracket can be largely on the same plane. On the other hand, when the movable carrier moves in the XY plane, the movable carrier can directly drive the image sensor module to move, and the movement of the image sensor module is less affected by the movable circuit board.

[0047] In one possible implementation, the image stabilization motor includes a first circuit board and an image stabilization driver chip; the first circuit board is fixed to the base plate of the first bracket; the first drive coil and the image stabilization driver chip are both fixed to the first circuit board, and the input and output terminals of the first drive coil form a current loop through the first circuit board and the image stabilization driver chip.

[0048] In one possible implementation, the base plate of the first bracket is provided with a first clearance hole, and the first circuit board is provided with a second clearance hole, with the first clearance hole and the second clearance hole being arranged opposite to each other; the movable circuit board includes an electrical connection part, which is fixed to a first fixing part, a portion of which passes through the first clearance hole and is located in the second clearance 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 driving 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.

[0049] Understandably, compared to traditional main camera image stabilization solutions, this implementation separates the image sensor module, active circuit board, first circuit board, and image stabilization driver chip along the Z-axis. By setting an electrical connection on the active circuit board, the image sensor and image stabilization driver chip are electrically connected, effectively utilizing the Z-axis space and further improving the XY plane space utilization.

[0050] In one possible implementation, the image stabilization motor includes a second circuit board fixed to a second bracket, and a second drive coil fixed to the second circuit board. The second drive coil forms a current loop with the image stabilization drive chip through the second circuit board, conductive components within the movable carrier, and the first circuit board. This simplifies the electrical connection path between the second drive coil and the image stabilization drive chip.

[0051] In one possible implementation, the fixing carrier includes a top plate, a first side plate and a second side plate disposed opposite to each other, with the top plate connected between the first side plate and the second side plate;

[0052] The top plate is set at an obtuse angle to the first side plate, and / or the top plate is set at an obtuse angle to the second side plate;

[0053] At least a portion of the top plate forms a magnetic shielding sheet, the first side of which is the surface of the top plate facing the inside of the fixed carrier, and the second side of which is the surface of the top plate facing away from the outside of the fixed carrier.

[0054] It is understandable that by setting the top plate and the first side plate at an obtuse angle, and / or setting the top plate and the second side plate at an obtuse angle, the fixed carrier is made to roughly form a "pyramid" shape. In this case, the second drive coil is located on one side of the top plate of the fixed carrier, the first drive magnetic component and the second drive magnetic component are located on the top plate of the fixed carrier, and the second drive coil is located on the bottom side of the fixed carrier. Thus, in this implementation, the image stabilization motor has a "pyramid" layered structure, with the second drive coil arranged at the top layer, the first drive magnetic component and the second drive magnetic component arranged from top to bottom in the middle layer, and the first drive coil arranged at the bottom layer of the pyramid. The overall combination realizes the image stabilization function of the three-axis decoupled image sensor.

[0055] In one possible implementation, the image stabilization motor further includes a guide bracket, which includes a first support portion, a second support portion, and a third support portion;

[0056] The first support, the second support, and the third support are connected to the first bracket of the movable carrier through multiple first support members, and to the fixed carrier through multiple second support members, so that the relative movement direction between the movable carrier and the guide bracket is different from the relative movement direction between the guide bracket and the fixed carrier.

[0057] Understandably, the movable carrier is movably connected to the fixed carrier via guide supports, making it less prone to rotation relative to the fixed carrier. This results in a more stable movement of the movable carrier.

[0058] In one possible implementation,

[0059] The driving magnetic component includes a first driving magnetic component and a second driving magnetic component; 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 driving coil; the first driving magnetic component 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 component is located between the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil.

[0060] 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 component to drive the movable carrier to move relative to the fixed carrier along the first direction.

[0061] 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, which is different from the first direction.

[0062] It is understandable that by positioning the first driving magnetic component between the first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil, the magnetic field lines on both sides of the first driving magnetic component can be fully utilized by the first sub-driving coils of both the first and second driving coils. The high magnetic field utilization of the first driving magnetic component is beneficial for improving the drive stroke of the anti-shake motor.

[0063] It is understandable that by positioning the second driving magnetic component between the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil, the magnetic field lines on both sides of the second driving magnetic component can be fully utilized by the second sub-driving coils of the first and second driving coils. The high magnetic field utilization of the second driving magnetic component is beneficial for improving the drive stroke of the anti-shake motor.

[0064] In one possible implementation, the fixed carrier is provided with a first through hole and a second through hole, a first driving magnetic element is located in the first through hole, and a second driving magnetic element is located in the second through hole.

[0065] In one possible implementation, the driving magnetic element includes a third driving magnetic element; 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 element 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 element to drive the movable carrier to rotate relative to the fixed carrier.

[0066] It is understandable that by positioning the third driving magnetic component between the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil, the magnetic field lines on both sides of the third driving magnetic component can be fully utilized by the third sub-driving coils of the first and second driving coils. The high magnetic field utilization of the third driving magnetic component is beneficial for improving the drive stroke of the anti-shake motor.

[0067] In one possible implementation, the fixed carrier is provided with a third through hole, and the third driving magnetic component is located inside the third through hole.

[0068] Secondly, an image stabilization motor is provided. The image stabilization motor includes a fixed carrier, a movable carrier, a drive coil, a first drive magnetic component, and a second drive magnetic component. The movable carrier is used to fix the image sensor module. The drive coil is fixed to the fixed carrier, and both the first and second drive magnetic components are fixed to the movable carrier. The drive coil is located between the first and second drive magnetic components.

[0069] The drive coil faces the first and second drive magnetic components to drive the movable carrier to move relative to the fixed carrier.

[0070] It is understood that this embodiment provides a driving architecture for a magnetic coil similar to a "sandwich". Specifically, the driving coil is fixed to a fixed carrier, and both the first and second driving magnetic components are fixed to a movable carrier, with the driving coil located between the first and second driving magnetic components. Compared to a scheme where the first and second driving magnetic components are laid flat in the XY plane, the first driving magnetic component, the driving coil, and the second driving magnetic component of this application are arranged sequentially in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the dimensions in the XY-axis direction, thus significantly improving the space utilization rate in the Z-axis direction.

[0071] In addition, since the first driving magnetic element and the second driving magnetic element can be arranged along the Z-axis, the number of magnets of the first driving magnetic element and the second driving magnetic element arranged in the XY plane will not affect each other, which is conducive to maximizing the number of the first driving magnetic element and the second driving magnetic element.

[0072] It is understandable that, since the drive coil is fixed to a fixed carrier, and both the first and second drive magnetic components are fixed to a movable carrier, the anti-shake motor in this embodiment is a moving magnetic motor. Thus, compared to a moving coil motor, the electrical connection method of the drive coil in this embodiment is simpler.

[0073] It is understandable that, since the driving coil is located between the first driving magnetic component and the second driving magnetic component, and the first driving magnetic component and the second driving magnetic component are far apart, it is beneficial to reduce the crosstalk of the magnetic field lines of the first driving magnetic component and the second driving magnetic component, and to ensure the utilization rate of the magnetic field lines of the first driving magnetic component and the second driving magnetic component.

[0074] In one possible implementation, the drive coil includes a first drive coil and a second drive coil, and the second drive magnetic component includes a first sub-drive magnetic component; the first drive coil faces the first drive magnetic component to drive the movable carrier to move relative to the fixed carrier in a first direction; the second drive coil faces the first sub-drive magnetic component to drive the movable carrier to move relative to the fixed carrier in a second direction, which is different from the first direction.

[0075] Understandably, the first driving coil faces the first driving magnetic component to drive the movable carrier to move relative to the fixed carrier along the first direction X. The second driving coil faces the first sub-driving magnetic component 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 (i.e., the XY plane). When the camera module collects ambient light, if the electronic device experiences vibration in the XY plane due to external forces, the movement of the image sensor module in the XY plane can be controlled to counteract the vibration travel of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by vibration, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0076] In one possible implementation, the first driving coil and the second driving coil are arranged along a third direction, which is different from both the first and second directions.

[0077] Compared to the scheme where the first and second driving coils are laid out in the XY plane, the first and second driving coils of this application are arranged along the third direction, which can further utilize the space in the Z-axis direction and further compress the size in the XY-axis direction, thus greatly improving the space utilization rate in the Z-axis direction.

[0078] In one possible implementation, the anti-shake motor includes a motor circuit board fixed to a fixed carrier; the motor circuit board includes a first surface and a second surface arranged along a third direction, a first drive coil fixed to the first surface of the motor circuit board, and a second drive coil fixed to the second surface of the motor circuit board.

[0079] In one possible implementation, the fixed carrier has a mounting hole that connects to the inner space of the fixed carrier; at least a portion of the first drive coil is located within the mounting hole. In this way, on the one hand, the fixed carrier no longer needs to separate the first drive coil and the first drive magnetic element, allowing the first drive coil to be positioned as close as possible to the first drive magnetic element; on the other hand, in the Z-axis direction, the first drive coil and the fixed carrier have an overlapping area, thereby compressing the dimension in the Z-axis direction.

[0080] In one possible implementation, the drive coil includes a third drive coil facing the first sub-drive magnetic element to drive the movable carrier to rotate relative to the fixed carrier.

[0081] It is understandable that rotational compensation around the Z-axis is achieved by setting up a third drive coil and a first sub-drive magnetic component. For example, when the moving 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 for the moving carrier's counterclockwise rotation relative to the fixed carrier, thereby achieving rotational compensation around the Z-axis. Furthermore, since the third drive coil can share the same first sub-drive magnetic component with the second drive coil, the structure of the anti-shake motor is simplified, facilitating miniaturization of the anti-shake motor.

[0082] It is understandable that the third drive coil can share the first sub-drive magnetic component with the second drive coil. Therefore, the structure of the anti-shake motor in this embodiment is relatively simple.

[0083] In one possible implementation, there are multiple third drive coils; these multiple third drive coils are located on both sides of the second drive coil in the length direction, or on the same side of the second drive coil in the width direction. This results in a more compact arrangement between the third drive coils and the second drive coil.

[0084] In one possible implementation, the drive coil includes a fourth drive coil, which is arranged in the same layer as the second drive coil;

[0085] The second driving magnetic component includes a second sub-driving magnetic component, which is disposed in 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.

[0086] It is understandable that by additionally setting a fourth driving coil in the layer containing the second driving coil, and additionally setting a second sub-driving magnetic component in the layer containing the first sub-driving magnetic component, and utilizing the fourth driving coil and the second sub-driving magnetic component, the movable carrier can be driven to move relative to the fixed carrier along the first direction X. In this case, the fourth driving coil and the second sub-driving magnetic component can cooperate with the first driving coil and the first driving magnetic component, thereby significantly increasing the driving force of the movable carrier relative to the fixed carrier along the first direction X, which is beneficial for increasing the stroke of the movable carrier relative to the fixed carrier along the first direction X.

[0087] In one possible implementation, the active carrier includes a first support and a second support;

[0088] The first bracket includes a base plate, a first protrusion, and a second protrusion. The first protrusion and the second protrusion protrude from the same side of the base plate. The second bracket is fixedly connected to the first protrusion and the second protrusion, and is positioned opposite to and spaced apart from the base plate. At least a portion 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.

[0089] Understandably, since the movable carrier can be assembled from the first and second supports, when assembling the movable carrier with other structural components, the first and second supports can be assembled separately with the other structural components first, and then the second support can be fixed to the first support. This assembly method can reduce the assembly of other structural components with the movable carrier.

[0090] In one possible implementation, the movable carrier is movably connected to the fixed carrier via a connector.

[0091] In one possible implementation, there are three connectors distributed in different positions to support and fix the carrier at three points, thereby achieving a stable setting of the anti-shake motor.

[0092] In one possible implementation, the movable carrier has a first groove. The connector is located within the first groove. This prevents the connector from easily detaching from the movable carrier.

[0093] In one possible implementation, grease is provided between the connector and the first groove. This further reduces the friction between the connector and the fixed carrier, thereby better achieving a super-lubricated connector system. Furthermore, the connector is less likely to detach from the first groove.

[0094] In one possible implementation, the fixed carrier has a magnetic attraction element, and the movable carrier has a magnetic attraction element. The magnetic attraction between the magnetic attraction elements keeps the fixed carrier, the connector, and the movable carrier in contact.

[0095] Understandably, the magnetic components are arranged opposite each other. A magnetic force can be generated between the magnetic components. This magnetic force causes the movable carrier to tend to move closer to the fixed carrier, thus maintaining contact between the fixed carrier, the connecting parts, and the movable carrier. In this way, the movable carrier can stably hold the fixed carrier in the Z-axis direction, resulting in better stability of the movable carrier when moving relative to the fixed carrier.

[0096] In one possible implementation, the magnetic element is part of the fixed carrier.

[0097] In one possible implementation, there are multiple connectors arranged around the magnetic attracting element. This improves the stability of the moving carrier when it moves relative to the fixed carrier.

[0098] In one possible implementation, the image stabilization motor further includes a movable circuit board, which includes a first fixed part, an elastic part, and a second fixed part, with the elastic part connected between the first fixed part and the second fixed part; a movable carrier is fixed to the first fixed part, and a fixed carrier is fixed to the second fixed part; and an image sensor module is fixed to the side of the first fixed part away from the movable carrier.

[0099] It is understandable that when the movable carrier moves relative to the fixed carrier along the first direction X, the elastic part of the movable circuit board deforms along the first direction X. The first fixed part of the image sensor module and 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 part of the movable circuit board deforms along the second direction Y. The first fixed part of the image sensor module and 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 forces, the movement of the image sensor module in the XY plane can be controlled to counteract the shaking stroke of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by shaking, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0100] In one possible implementation, the elastic part is spiral, zigzag, or curved. This increases the length of the elastic part, thereby significantly reducing its elastic coefficient. The movement stroke of the moving circuit board is less restricted, which facilitates setting a larger anti-shake stroke for the moving carrier. Furthermore, the spiral-shaped, low-K-value elastic part can effectively compress the dimensions in the X and Y axes while maintaining a small size in the Z-axis direction, reducing crosstalk in XY plane motion and optimizing electromagnetic drive performance and power consumption.

[0101] In one possible implementation, the length of the elastic portion is greater than half the perimeter of the edge of the first fixed portion. This increases the length of the elastic portion, thereby significantly reducing its elastic modulus.

[0102] In one possible implementation, the elastic portion surrounds at least half of the edge of the first fixed portion, or the elastic portion surrounds the edge of the first fixed portion in multiple turns. This increases the length of the elastic portion, thereby significantly reducing its elastic modulus.

[0103] In one possible implementation, the movable circuit board further includes a reinforcing portion located within the first fixing portion, and the movable carrier is fixed to the reinforcing portion. It is understood that the reinforcing portion can be a steel plate or other metal plate. The reinforcing portion can improve the overall strength of the first fixing portion.

[0104] In one possible implementation, the first bracket further includes a fixing protrusion, which protrudes from the base plate and is located on the side of the base plate away from the first protrusion and / or the second protrusion. The fixing 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 on the same plane. On the other hand, when the movable carrier moves in the XY plane, the movable carrier can directly drive the image sensor module to move, and the movement of the image sensor module is less affected by the movable circuit board.

[0105] In one possible implementation, the drive coil is electrically connected to a second fixed part of the movable circuit board via a motor circuit board.

[0106] It is understood that in this embodiment, where the drive coil is electrically connected to the outside of the image sensor assembly, the motor circuit board no longer needs to be electrically connected to the first fixing part and the elastic part of the movable circuit board. In this embodiment, the drive chip can be directly electrically connected to the second fixing part 3 of the movable circuit board. This solution, where the drive chip is electrically connected to the outside of the image sensor assembly, is simpler and easier to mass-produce.

[0107] In one possible implementation, the image stabilization motor includes a driver chip. The driver chip is fixed to and electrically connected to the motor circuit board, and the input and output terminals of the drive coil form a current loop through the motor circuit board and the driver chip.

[0108] In one possible implementation, the fixing carrier includes a top plate, a first side plate and a second side plate disposed opposite to each other, with the top plate connected between the first side plate and the second side plate;

[0109] The top plate is set at an obtuse angle to the first side plate, and / or the top plate is set at an obtuse angle to the second side plate;

[0110] The drive coil is fixed to the top plate.

[0111] It is understandable that by setting the top plate and the first side plate at an obtuse angle, and / or setting the top plate and the second side plate at an obtuse angle, the fixed carrier is made to roughly form a "pyramid" shape. In this case, the first driving magnetic component is located on one side of the top plate of the fixed carrier, the driving coil is located on the top plate of the fixed carrier, and the second driving magnetic component is located on the bottom side of the fixed carrier. Thus, in this implementation, the image stabilization motor has a pyramid-shaped stacked architecture. The second driving magnetic component is arranged at the top layer, the middle layer consists of the first driving coil, the second driving coil, the third driving coil, and the fourth driving coil arranged from top to bottom, and the first driving magnetic component is arranged at the bottom layer of the pyramid. The overall combination realizes the image stabilization function of the three-axis decoupled image sensor.

[0112] Thirdly, an image sensor assembly is provided. The image sensor assembly includes an image sensor module and a stabilization motor as 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 a stabilization motor as described in the second aspect above, wherein the image sensor module is fixed to a movable carrier.

[0113] It is understandable that when the moving carrier moves along the first direction X, the image sensor module can follow the moving carrier along the first direction X. When the moving carrier moves relative to the fixed carrier along the second direction Y, the image sensor module can follow the moving carrier along the second direction Y. Therefore, the moving carrier can control the image sensor module to move along a plane perpendicular to the third direction Z (i.e., the XY plane). When the image sensor assembly is applied to a camera module, if the camera module experiences shaking in the XY plane, the movement of the image sensor module in the XY plane can be controlled to counteract the shaking stroke of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by shaking, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0114] Furthermore, when the moving carrier rotates clockwise relative to the fixed carrier, the moving 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-driving coil of the second driving coil, a compensating driving force is obtained to allow the moving carrier to rotate counterclockwise relative to the fixed carrier, thereby achieving rotational compensation of the moving carrier around the Z-axis. At this time, the image sensor module also undergoes rotational compensation around the Z-axis to counteract the jitter stroke caused by the rotation of the camera module around the Z-axis, thereby avoiding or reducing the positional offset of the camera module due to jitter, and thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0115] In one possible implementation, the image sensor module is fixed to the side of the moving carrier away from the first drive coil. This makes it less likely for the image sensor module to interfere with the image stabilization motor.

[0116] Alternatively, the image sensor module can be fixed to the side of the movable carrier furthest from the first driving magnetic component. This reduces the likelihood of interference between the image sensor module and the image stabilization motor.

[0117] Fourthly, a camera module is provided. The camera module includes a first optical element and an image sensor assembly as described above. The image sensor assembly is located on the image side of the first optical element.

[0118] Understandably, if the camera module shakes in the XY plane, the image stabilization motor can control the movement of the image sensor module in the XY plane to counteract the shaking travel of the camera module in the XY plane, thereby avoiding or reducing the positional offset of the camera module caused by shaking, thus achieving optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0119] 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 optical axis direction of the camera module.

[0120] In one possible implementation, the first optical path conversion element includes a first side, a second side, and a third side connected to each other. After passing through the first optical element, light enters the first optical path conversion element, and after total internal reflection by the second side and reflection by the third side of the first optical path conversion element, it propagates to the image sensor assembly.

[0121] The image sensor assembly is located on the same side as the third side of the first optical path conversion element. In this way, on the one hand, the image sensor assembly can effectively utilize the space of the third side of the first optical path conversion element; on the other hand, the image sensor assembly and the first optical path conversion element have an overlapping area in the thickness direction of the electronic device, and the position of the image sensor assembly does not easily increase the thickness of the electronic device.

[0122] In one possible implementation, the first and second sides of the first optical path conversion element are arranged perpendicularly, and the third side of the first optical path conversion element is an inclined surface.

[0123] In one possible implementation, the camera module further includes a second optical conversion element located on the object side of the first optical element, the second optical conversion element being used to change the optical axis direction of the camera module.

[0124] Fifthly, an electronic device is provided. The electronic device includes a device housing and a camera module as described above, the camera module being disposed within the device housing. It is understood that the camera module of the electronic device of this implementation has a stabilizing motor with a larger rated stroke. Attached Figure Description

[0202] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0203] The object side is defined by the lens; the side where the object is located is called the object side, and the surface of the lens closest to the object side is called the object side surface.

[0204] The image side is the side on which the image of the subject is located, with the lens as the boundary. The surface of the lens closest to the image side is called the image side surface.

[0205] The optical axis is a perpendicular axis passing through the center of a lens. The lens optical axis is the axis passing through the centers of all the lenses in the lens. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens should have all the light rays converging at a single point behind the lens; this point where all the light rays converge is called the focal point.

[0206] Sensor chip optoelectronic image stabilizer (SOI S);

[0207] Trace suspension assembly (TSA) is a component where the reed and signal line are integrally molded.

[0208] Mov i ngt ilt: Dynamic tilt of the active platform (tilt about the x-axis or y-axis) characterizing the motion stability of SOIS;

[0209] ShiftZ: Characterizes the displacement fluctuation of the active platform in the Z-axis (optical axis direction) of SOI S motion stability.

[0210] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," "joining," and "joining" should be interpreted broadly. For example, "joining" can be a detachable connection or a 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. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the relative positional relationship can change. "Sliding connection" refers to a connection where the relative positional relationship can change. Furthermore, the integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components. Components A and B can be arranged relative to each other such 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, with projection C and projection D at least largely overlapping. In some embodiments, the majority overlap can be any of the following: projection C is entirely within projection D; or projection D is entirely within projection C; or 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.

[0211] The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," "upper," and "lower," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0212] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0213] Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application.

[0214] like Figure 1 As shown, the electronic device 1000 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, or other devices with camera functions. Figure 1 The electronic device 1000 of the embodiment shown is illustrated using a mobile phone as an example.

[0215] Figure 2 yes Figure 1 A partial cross-sectional view of the electronic device 1000 shown in one embodiment on line AA.

[0216] like Figure 1 and Figure 2As shown, 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 The camera module 100 is schematically shown using a dashed box. It is understandable that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the accompanying drawings below. Furthermore, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300.

[0217] like Figure 1 and Figure 2 As shown, in some embodiments, the screen 300 is mounted on the device housing 200 and together with the device housing 200 encloses the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as a battery, receiver, or microphone. The screen 300 can be a flat screen or a curved screen.

[0218] For example, the camera module 100 may 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 that of the attached device. Figure 1 The shape shown can be a circle, an ellipse, or an irregular shape. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting part 201. The camera module 100 can capture the light entering the interior of the electronic device 1000.

[0219] like Figure 2 As shown, 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 is understood that the first optical path conversion element 102 can be used to change the optical axis direction of the camera module 100. The image sensor assembly 101 can be used to convert image information carried by ambient light into electrical signals.

[0220] 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 where the first optical element 103, the first optical path conversion element 102, and the image sensor assembly 101 are separately arranged, the camera module 100 of this embodiment is smaller in size, which is beneficial for miniaturizing the camera module 100 and thus saving internal space in the electronic device 1000.

[0221] For example, 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 can move along the optical axis. For example, as Figure 2 As shown, the first optical element 103 includes a first lens group 1031 and a second lens group 1032. The first lens group 1031 can move along the optical axis. The second lens group 1032 can be a fixed-position lens group.

[0222] like Figure 2 As shown, exemplarily, the first optical path conversion element 102 may 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 connected to each other. The first side surface 1021 of the first optical path conversion element 102 may face the first optical element 103. It is understood that at least part of the light enters the first optical element 103, passes through the first optical element 103, enters the first optical path conversion element 102 via the first side surface 1021, and then, after total internal reflection by the third side surface 1023 and reflection by the second side surface 1022, propagates to the image sensor assembly 101.

[0223] For example, the second side 1022 of the first optical path conversion element 102 may face the screen 300. The image sensor assembly 101 is located on the same side as the third side 1023 of the first optical path conversion element 102. In this way, on the one hand, the image sensor assembly 101 can effectively utilize the space where the third side 1023 of the first optical path conversion element 102 is located; on the other hand, 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, and the position of the image sensor assembly 101 does not easily increase the thickness of the electronic device 1000.

[0224] In one embodiment, the first side surface 1021 and the second side surface 1022 of the first optical path conversion element 102 are arranged vertically, and the third side surface 1023 of the first optical path conversion element 102 is an inclined surface.

[0225] Figure 3 yes Figure 2 The image sensor assembly 101 shown is illustrated in a structural schematic diagram of one embodiment.

[0226] Please see Figure 3 and combined Figure 2As shown, the image sensor assembly 101 includes a top surface 10a and a bottom surface 10d arranged opposite to each other, and a first side surface 10b and a second side surface 10c arranged opposite to each other. 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 to the third side surface 1023 of the first optical path conversion element 102.

[0227] It is understood that in one embodiment, the image sensor assembly 101 does not include a 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 larger volume for the image sensor assembly 101, which is not conducive to miniaturization. However, in this embodiment, by forming a top surface 10a on the image sensor assembly 101, the space on the side where the top surface 10a is located can be eliminated. This results in a smaller volume for the image sensor assembly 101, which is beneficial for miniaturization.

[0228] Exemplarily, the first side surface 10b of the image sensor assembly 101 is set at an acute angle to the bottom surface 10d. It is understood that, in one embodiment, if the length of the bottom surface 10d of the image sensor assembly 101 remains constant, and the first side surface 10b of the image sensor assembly 101 is perpendicular to the bottom surface 10d, then the first side surface 10b of the image sensor assembly 101 easily increases the height of the camera module 100 (i.e., the first side surface 10b of the image sensor assembly 101 will protrude). Figure 2 (The dashed box). In this embodiment, by setting the first side 10b of the image sensor assembly 101 to form an acute angle with the bottom surface 10d, the first side 10b of the image sensor assembly 101 is prevented from significantly increasing the height of the camera module 100.

[0229] Exemplarily, the second side 10c of the image sensor assembly 101 is set at an acute angle to the bottom surface 10d. It is understood that, in one embodiment, if the length of the bottom surface 10d of the image sensor assembly 101 remains constant, and the second side 10c of the image sensor assembly 101 is made perpendicular to the bottom surface 10d, then the second side 10c of the image sensor assembly 101 easily increases the length of the camera module 100 (i.e., the second side 10c of the image sensor assembly 101 will extend beyond its normal position). Figure 2 (The dashed box). In this embodiment, by setting the second side 10c of the image sensor assembly 101 to form an acute angle with the bottom surface 10d, the second side 10c of the image sensor assembly 101 is prevented from significantly increasing the height of the camera module 100.

[0230] For example, the angle between the first side 10b and the bottom surface 10d of the image sensor assembly 101 is smaller than the angle between the second side 10c and the bottom surface 10d of the image sensor assembly 101.

[0231] For example, the first side surface 10b of the image sensor assembly 101 is set at an obtuse angle to the top surface 10a. And / or, the second side surface 10c of the image sensor assembly 101 is set at an obtuse angle to the top surface 10a. In this way, the image sensor assembly 101 can make greater use of the space where the third side surface 1023 of the first optical path conversion element 102 is located.

[0232] For example, the first side 10b of the image sensor assembly 101 is arranged parallel to the second side 1022 of the first optical path conversion element 102.

[0233] For example, the second side 10c of the image sensor assembly 101 is arranged parallel to the first side 1021 of the first optical path conversion element 102.

[0234] For example, the image sensor assembly 101 may be shaped like a pyramid.

[0235] like Figure 2 As shown, the camera module 100 also 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 optical axis direction of the camera module 100.

[0236] For example, the second optical path conversion element 104 may include a prism. The light-incident side of the second optical path conversion element 104 is disposed opposite to the light-transmitting portion 201. At this time, light passing through the light-transmitting portion 201 can enter the second optical path conversion element 104, and after being reflected by the second optical path conversion element 104, it propagates 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 being totally internally reflected by the third side surface 1023 and reflected by the second side surface 1022 of the first optical path conversion element 102, it propagates to the image sensor assembly 101.

[0237] 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.

[0238] In other embodiments, the second optical path conversion element 104 may further include a stabilization motor. The stabilization motor is used to drive the prism movement of the second optical path conversion element 104 to achieve optical image stabilization of the camera module 100.

[0239] It is understood that the above description only illustrates one embodiment of the image sensor assembly 101 applied to the camera module 100. In other embodiments, the image sensor assembly 101 may also be applied to camera modules 100 with other structures. Specifically, this application does not limit the application.

[0240] Figure 4 yes Figure 3 A partially exploded schematic diagram of one embodiment of the image sensor assembly 101 shown.

[0241] like Figure 3 and Figure 4 As shown, the image sensor assembly 101 includes a stabilization motor 10, an image sensor module 20, an upper housing 30, and a lower housing 40. For ease of description, the width direction of the image sensor assembly 101 is defined as the X-axis. The length direction of the image sensor assembly 101 is defined as the Y-axis. The thickness direction of the image sensor assembly 101 is defined as the Z-axis. It can be understood that the coordinate system settings of the image sensor assembly 101 can be flexibly set according to specific practical needs.

[0242] It is understood that the image stabilization 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 shakes in the XY plane due to external forces, the image stabilization motor 10 can control the movement of the image sensor module 20 in the XY plane to counteract the shaking stroke of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by shaking. The camera module 100 of this application can control the movement of the image sensor module 20 in the XY plane through the image stabilization motor 10 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0243] Figure 5 yes Figure 4 A partially exploded view of one embodiment of the anti-shake motor 10 shown.

[0244] like Figure 5 As shown, the anti-shake motor 10 includes a fixed carrier 11, a movable carrier 12 (also called a motion carrier), a driving magnetic component 13, a first driving coil 14, and a second driving coil 15.

[0245] For example, the active carrier 12 includes a first support 121 and a second support 122.

[0246] For example, the driving magnetic element 13 includes a first driving magnetic element 131 and a second driving magnetic element 132.

[0247] For example, the second drive coil 15 includes a first sub-drive coil 151 and a second sub-drive coil 152.

[0248] It is understood that the image stabilization motor 10 may include more or fewer structures. For example, when the image stabilization motor 10 includes more structures, it may also include a first circuit board 16, a second circuit board 17, a movable circuit board 18 (also called a TSA, or elastic circuit board), a rolling element 191, and a magnetic element 192. Exemplarily, the rolling element 191 may be a single ball, a group of multiple balls, a sliding shaft, or a raised structure.

[0249] Figure 6 yes Figure 5 The diagram shows the structure of the fixed carrier 11 at different angles. Figure 7 yes Figure 5 The diagram shows the structure of the fixed carrier 11 from another angle.

[0250] like Figure 6 and Figure 7 As shown, the fixing carrier 11 includes a top plate 112, a first side plate 113 and a second side plate 114 disposed opposite to each other, and a third side plate 115 and a fourth side plate 116 disposed opposite to each other. The top plate 112 connects the first side plate 113 and the second side plate 114, and also connects the third side plate 115 and the fourth side plate 116. The third side plate 115 and the fourth side plate 116 connect 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 the inner space of the fixing carrier 11.

[0251] For example, the top plate 112 is set at an obtuse angle to the first side plate 113. And / or, the top plate 112 is set at an obtuse angle to the second side plate 114.

[0252] For example, the fixing carrier 11 is provided with a receiving groove 117. The opening of the receiving groove 117 is formed on the top plate 112.

[0253] For example, the fixing carrier 11 is provided with a first through hole 118 and a second through hole 119 spaced apart. The first through hole 118 and the second through hole 119 connect the inner space of the fixing carrier 11 to the outer space. In one embodiment, the first through hole 118 is formed on the first side plate 113. The second through hole 119 is formed on the second side plate 114.

[0254] Figure 8 yes Figure 6A partially exploded view of one embodiment of the fixed carrier 11 shown.

[0255] like Figure 8 As shown, the fixing carrier 11 includes a metal part 11a and an insulating part 11b. The metal part 11a can be embedded in the insulating part 11b. Exemplarily, the metal part 11a can be integrally formed with the insulating part 11b by means of in-mold molding or other methods. In this way, the overall strength of the fixing carrier 11 is better.

[0256] For example, the insulating member 11b includes a first insulating portion 111b, a second insulating portion 112b and a third insulating portion 113b disposed opposite to each other, and a fourth insulating portion 114b and a fifth insulating portion 115b disposed opposite to each other. The first insulating portion 111b is connected between the second insulating portion 112b and the third insulating portion 113b, and is also 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.

[0257] like Figure 8 As shown, the metal component 11a includes a first metal component 111a, a second metal component 112a, and a third metal component 113a. Exemplarily, the first metal component 111a may be embedded in the first insulating portion 111b. The second metal component 112a may be embedded in the second insulating portion 112b. The third metal component 113a may be embedded in the third insulating portion 113b.

[0258] Please see Figure 8 and combined Figure 6 and Figure 7 The first metal member 111a and the first insulating portion 111b can be formed as the top plate 112 of the fixing carrier 11. The second metal member 112a and the second insulating portion 112b can be formed as the first side plate 113 of the fixing carrier 11. The third metal member 113a and the third insulating portion 113b can be formed as the second side plate 114 of the fixing carrier 11. The fourth insulating portion 114b can be formed as the third side plate 115 of the fixing carrier 11. The fifth insulating portion 115b can be formed as the fourth side plate 116 of the fixing carrier 11. The first through hole 118 and the second through hole 119 can be formed on 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 form a receiving groove 117.

[0259] like Figure 8 As shown, the first metal member 111a includes a main body 114a and a plurality of extensions 115a. The plurality of extensions 115a are spaced apart and connected to the edge of the main body 114a. Exemplarily, the plurality of extensions 115a may be bent relative to the main body 114a.

[0260] like Figures 6 to 8 As shown, at least a portion of the main body 114a of the first metal member 111a forms a magnetic shielding sheet 111. The magnetic shielding sheet 111 may be exposed relative to the first insulating portion 111b. The magnetic shielding sheet 111 includes a first surface 1111 and a second surface 1112 disposed opposite to each other. The first surface 1111 of the magnetic shielding sheet 111 is the surface of the top plate 112 facing the inside of the fixing carrier 11, and the second surface 1112 of the magnetic shielding sheet 111 is the surface of the top plate 112 facing away from the outside of the fixing carrier 11. In other embodiments, the magnetic shielding sheet 111 may also be embedded within the first insulating portion 111b.

[0261] For example, a plurality of extensions 115a of the first metal member 111a may be exposed relative to the first insulating portion 111b.

[0262] It is understood that the above description is only illustrative of the structure of a fixed carrier 11. In other embodiments, the structure of the fixed carrier 11 is not specifically limited.

[0263] Figure 9 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 1 .

[0264] Please see Figure 9 and combined Figure 7 As shown, the first driving magnetic component 131 of the driving magnetic component 13 is fixed to the first surface 1111 of the magnetic shielding sheet 111, that is, the first driving magnetic component 131 is located in the inner space of the fixed carrier 11.

[0265] Exemplarily, the first driving magnetic element 131 may include a plurality of magnets arranged in a first direction X. The implementation structure of the first driving magnetic element 131 can be varied. For example, the first driving magnetic element 131 may include at least three magnets, wherein the polarization directions of the two adjacent magnets located at the edges are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the middle magnet points from one magnet to another. It is understood that... Figure 9 Six magnets are shown only schematically. For example, the first driving magnetic component 131 can be a Hellbeck magnet array. Furthermore, the first driving magnetic component 131 can adopt a dual-magnet structure, such as consisting of two magnets with opposite polarities. It is understood that when the first driving magnetic component 131 adopts a multi-group Hellbeck magnet array arrangement, the magnetic field line distribution is further compressed, effectively increasing the magnetic thrust and improving the utilization rate of the magnetic field lines.

[0266] For example, the first driving magnetic element 131 may include a magnet, that is, the first driving magnetic element 131 may adopt a single magnet structure, for example, it may consist of a single magnet, which includes 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. Furthermore, the two parts with opposite polarity directions may form a magnetic unit. A magnet may include multiple magnetic units. Multiple magnetic units are arranged in the first direction X.

[0267] Figure 10 yes Figure 9 The diagram shows a partial image stabilization motor 10 from another angle.

[0268] Please see Figure 10 and combined Figure 6 As shown, the second driving magnetic element 132 of the driving magnetic element 13 is fixed to the second surface 1112 of the magnetic shielding sheet 111. In one embodiment, the second driving magnetic element 132 is located in the receiving groove 117 of the fixed carrier 11.

[0269] It is understood that in this embodiment, the first driving magnetic element 131 is fixed to the first surface 1111 of the magnetic shielding sheet 111, and the second driving magnetic element 132 is fixed to the second surface 1112 of the magnetic shielding sheet 111, thereby fixing the driving magnetic element 13 to the fixing carrier 11. Furthermore, the first driving magnetic element 131 and the second driving magnetic element 132 can be separately fixed to different positions on the fixing carrier 11, and the magnetic shielding sheet 111 can separate the first driving magnetic element 131 and the second driving magnetic element 132.

[0270] Exemplarily, the second driving magnetic element 132 may include a plurality of magnets arranged in the second direction Y. The second driving magnetic element 132 can be implemented in various ways. For example, the second driving magnetic element 132 may include at least three magnets. In adjacent pairs of magnets, the polarity directions of the two magnets are opposite. It is understood that... Figure 10 Only three magnets are shown schematically. For example, the second driving magnetic component 132 can adopt a dual-magnet structure, such as consisting of two magnets with opposite polarities. For another example, the second driving magnetic component 132 can be a Hellbeck magnet array. For yet another example, the second driving magnetic component 132 can include at least three magnets, where the two adjacent magnets on the edges have opposite polarization directions perpendicular to the arrangement direction of the three magnets, and the polarization direction of the middle magnet points from one magnet to another. It is understood that when the second driving magnetic component 132 adopts a multi-group Hellbeck magnet array arrangement, the magnetic field line distribution is further compressed, effectively increasing the magnetic thrust and improving the utilization rate of the magnetic field lines.

[0271] For example, the second driving magnetic element 132 may include a magnet, that is, the second driving magnetic element 132 may adopt a single magnet structure, for example, it may consist of a single magnet, which includes 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. Furthermore, the two parts with opposite polarity directions may form a magnetic unit. A single magnet may include multiple magnetic units. Multiple magnetic units are arranged in the second direction Y.

[0272] Figure 11 yes Figure 5 The diagram shows the structure of the first support 121 from another angle.

[0273] like Figure 11 As shown, the first bracket 121 includes a base plate 1211, a first protrusion 1212, and a second protrusion 1213. The first protrusion 1212 and the second protrusion 1213 protrude from the same side of the base plate 1211.

[0274] For example, the base plate 1211 is provided with a first clearance hole 1214. The first clearance hole 1214 may be located between the first protrusion 1212 and the second protrusion 1213. The number of first clearance holes 1214 may be two. The shape of the first clearance hole 1214 may be elongated. In other embodiments, the position, size, number and shape of the first clearance hole 1214 are not specifically limited.

[0275] For example, the first bracket 121 has a plurality of first limiting protrusions 1215. The plurality of first limiting protrusions 1215 can limit other structural components. The position, size, number and shape of the first limiting protrusions 1215 are not specifically limited. In addition, the first limiting protrusions 1215 can also be replaced by a groove structure.

[0276] For example, the first bracket 121 has a plurality of first pin terminals 1216. The plurality of first pin terminals 1216 can be used for electrical connection with other structural components.

[0277] Understandable, Figure 11 Some of the first limiting protrusions 1215 and the first pin terminals 1216 are labeled only schematically.

[0278] Figure 12 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 2 .

[0279] like Figure 12 As shown, the image stabilization motor 10 includes an image stabilization driver chip 193. The image stabilization driver chip 193 is fixed to the first circuit board 16 and electrically connected to the first circuit board 16.

[0280] For example, the image stabilization 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. At this time, 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.

[0281] For example, the first circuit board 16 is provided with a second clearance hole 161. The number of second clearance holes 161 may be two. The shape of the second clearance hole 161 may be elongated. In other embodiments, the position, size, number and shape of the second clearance hole 161 are not specifically limited.

[0282] For example, the first circuit board 16 has a plurality of second pin terminals 162. The plurality of second pin terminals 162 can be used for electrical connection with other structural components.

[0283] Figure 13 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 3 .

[0284] Please see Figure 13 and combined Figure 11 and Figure 12 As shown, the first circuit board 16 is fixed to the movable carrier 12. Exemplarily, the first circuit board 16 is fixed to the base plate 1211 of the first bracket 121. At least a portion of the first circuit board 16 may be located between the first protrusion 1212 and the second protrusion 1213.

[0285] For example, the first circuit board 16 is provided with a second clearance hole 161 which is disposed opposite to the first clearance hole 1214 of the first bracket 121.

[0286] For example, the plurality of 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 first circuit board 16. At this time, the connection between the first circuit board 16 and the first bracket 121 is more stable. For example, the number of first limiting protrusions 1215 is two. 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.

[0287] Figure 14 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 4 .

[0288] like Figure 14As shown, the first drive coil 14 is fixed to the first circuit board 16 and electrically connected to the first circuit board 16. The first drive coil 14 is fixed to the base plate 1211 of the first bracket 121 through the first circuit board 16.

[0289] For example, the input and output terminals of the first drive coil 14 form a current loop through the first circuit board 16 and the anti-shake drive chip 193.

[0290] For example, the plurality of 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 first drive coil 14. At this time, 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 inside the first drive coil 14 and abut against the first drive coil 14 in the first direction X.

[0291] Figure 15 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 5 .

[0292] like Figure 15 As shown, the base plate 1211 of the first support 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. Exemplarily, there are three rolling elements 191 and three rolling element grooves 1217. The three rolling elements 191 are disposed in the three rolling element grooves 1217 in a one-to-one correspondence.

[0293] For example, grease is provided between the rolling element 191 and the rolling element groove 1217.

[0294] like Figure 15 As shown, the base plate 1211 of the first support 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 attracting element 192. The magnetic attracting element 192 is located in the receiving groove 1218, that is, the movable carrier 12 is provided with a magnetic attracting element 192. Exemplarily, there are three magnetic attracting elements 192 and three receiving grooves 1218. The three magnetic attracting elements 192 are arranged one-to-one in the three receiving grooves 1218.

[0295] For example, three magnetic attracting elements 192 are disposed one-to-one around the three rolling elements 191.

[0296] It is understandable that by setting both the rolling element 191 and the magnetic element 192 on the first bracket 121, that is, by setting both the rolling element 191 and the magnetic element 192 on the same structural component, the relative positions of the rolling element 191 and the magnetic element 192 are not likely to change significantly when the first bracket 121 moves relative to each other.

[0297] Figure 16 yes Figure 5 The diagram shows the structure of the second support 122 at different angles.

[0298] like Figure 16 As shown, the second bracket 122 includes a top surface 1221 and a bottom surface 1222 that are disposed opposite to each other.

[0299] 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 other structural components. The position, size, number and shape of the second limiting protrusions 1223 are not specifically limited.

[0300] For example, the bottom surface 1222 of the second bracket 122 is provided with a limiting post 1224. The limiting post 1224 can limit the movement of other structural components. There are no specific limitations on the position, size, number, and shape of the limiting post 1224.

[0301] For example, the second bracket 122 is provided with a fixing hole 1225. The number of fixing holes 1225 can be one or more. There are no specific limitations on the position, size, number and shape of the fixing holes 1225.

[0302] Figure 17 yes Figure 5 The diagram shows the structure of the second circuit board 17 from another angle.

[0303] like Figure 17 As shown, the second circuit board 17 has a plurality of third pin terminals 171. The plurality of third pin terminals 171 can be used for electrical connection with other structural components.

[0304] For example, 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.

[0305] like Figure 17 As shown, the image stabilization motor 10 includes a third position sensor 173. The third position sensor 173 is fixed to and electrically connected to the second circuit board 17.

[0306] Figure 18 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 5 .

[0307] Please see Figure 18 and combined Figure 16 and Figure 17 As shown, 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.

[0308] 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 second circuit board 17. At this time, 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.

[0309] 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.

[0310] Figure 19 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 6 .

[0311] like Figure 19 As shown, the second drive coil 15 is fixed to the second circuit board 17 and electrically connected to the second circuit board 17. At this time, the second drive coil 15 is fixed to the second bracket 122 through the second circuit board 17.

[0312] For example, the first sub-drive coil 151 and the second sub-drive coil 152 are both fixed to the second circuit board 17 at intervals and are both electrically connected to the second circuit board 17.

[0313] 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 second drive coil 15. At this time, 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 inside the second drive coil 15 and abut against the second drive coil 15 in the first direction X.

[0314] Figure 20 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 7 . Figure 21 yes Figure 20 The diagram shows a partial image stabilization motor 10 from another angle.

[0315] like Figure 20 and Figure 21 As shown, the second bracket 122 is fixedly connected to the first protrusion 1212 and the second protrusion 1213, and is opposite to and spaced apart from the base plate 1211.

[0316] For example, the second bracket 122 can be fixedly connected to the first protrusion 1212 and the second protrusion 1213 by adhesive bonding.

[0317] For example, the first protrusion 1212, the second protrusion 1213, and the second bracket 122 all include metal portions. The metal portions of the first protrusion 1212 and the second protrusion 1213 are welded to the metal portion of the second bracket 122.

[0318] 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.

[0319] like Figure 20 and Figure 21 As shown, the first drive coil 14 and the second drive coil 15 are positioned facing each other. Furthermore, the second drive coil 15 is connected via a second circuit board 17 (see [link]). Figure 19 The conductive components in the first bracket 121 and the first circuit board 16 form a current loop with the anti-shake drive chip 193.

[0320] It is understood that the orientation of the first driving coil 14 and the second driving coil 15 can mean that the winding plane of the first driving coil 14 faces the winding plane of the second driving coil 15. For example, the winding planes of the first driving coil 14 and the second driving coil 15 can both be parallel to the XY plane.

[0321] For example, the length extension direction of the first drive coil 14 and the length extension direction of the second drive coil 15 are perpendicular to each other.

[0322] Figure 22 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 8 . Figure 23 yes Figure 22 A partial cross-sectional view of one embodiment of the anti-shake motor 10 at the BB line.

[0323] like Figure 22 and Figure 23 As shown, the movable carrier 12 is movably connected to the fixed carrier 11. Exemplarily, the movable carrier 12 can be movably connected to the fixed carrier 11 via a rolling element 191.

[0324] For example, the rolling element 191 and the extension 115a of the fixed carrier 11 ( Figure 8 The contact arrangement of the extension 115a) is illustrated at different angles. It can be understood that since the extension 115a of the fixed carrier 11 is made of metal, the friction between the rolling element 191 and the fixed carrier 11 is small, which is beneficial to improving the stable movement of the moving carrier 12 relative to the fixed carrier 11.

[0325] For example, there are three rolling elements 191, which are distributed in different positions to support the fixed carrier 11 at three points, so as to achieve a stable setting of the anti-shake motor 10.

[0326] For example, grease is provided between the rolling element 191 and the rolling element groove 1217. This further reduces the friction between the rolling element 191 and the fixed carrier 11, thereby better achieving the super-lubricated rolling element system. Furthermore, the rolling element 191 is less likely to detach from the rolling element groove 1217. In other embodiments, the rolling element 191 may also be integrally formed with the movable carrier 12.

[0327] For example, the magnetic shielding sheet 111 of the top plate 112 of the fixed carrier 11 is located between the bottom plate 1211 of the first support 121 and the second support 122, that is, a part of the fixed carrier 11 is located between the bottom plate 1211 of the first support 121 and the second support 122. The magnetic shielding sheets 111 of the top plate 112 of the fixed carrier 11 are all spaced apart from and opposite to the bottom plate 1211 of the first support 121 and the second support 122.

[0328] For example, the base plate 1211 of the first bracket 121 is located in the inner space of the fixing carrier 11. The first protrusion 1212 of the first bracket 121 can pass through the first through hole 118 of the fixing carrier 11 from the inner space of the fixing carrier 11 and extend to the outer space of the fixing carrier 11. In addition, the second protrusion 1213 of the first bracket 121 (see...) Figure 21 ) and the second through hole 119 of the fixed carrier 11 (see Figure 6 The positional relationship can be seen 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. Further details will not be provided here.

[0329] For example, the driving magnetic element 13 is located between the first driving coil 14 and the second driving coil 15. Both the first driving coil 14 and the second driving coil 15 face the driving magnetic element 13 to drive the movable carrier 12 to move relative to the fixed carrier 11. The first surface 1111 of the magnetic shielding sheet 111 faces the first driving coil 14, and the second surface 1112 of the magnetic shielding sheet 111 faces the second driving coil 15.

[0330] Figure 24 yes Figure 5 A partially exploded view of one embodiment of the anti-shake motor 10 shown.

[0331] Please see Figure 24 and combined Figure 23 As shown, the first drive coil 14 faces the first drive magnetic component 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. The first drive coil 14 and the first drive magnetic component 131 can constitute the first drive mechanism of the anti-shake motor 10.

[0332] It is understood that the first driving coil 14 being disposed facing the first driving magnetic element 131 means that the winding plane of the first driving coil 14 faces the first driving magnetic element 131. For example, the winding plane of the first driving coil 14 may be disposed parallel to the XY plane. Exemplarily, the first driving magnetic element 131 may have two opposite polarity directions ( Figure 24 The dashed line with an arrow indicates that... Figure 24 The diagram schematically illustrates that the first driving magnetic element 131 includes three sets of two opposite polarity directions. The polarity direction of the first driving magnetic element 131 can be perpendicular to the winding plane of the first driving coil 14. The two sections of the coil in one of the first driving coils 14 can be respectively arranged corresponding to the two polarity directions of the first driving magnetic element 131, and the current in the two sections of the coil ( Figure 24 (As shown by the solid line a with arrows) the flow is in the opposite direction. The side of the first driving magnetic element 131 facing the first driving coil 14 includes a south pole (S) and a north pole (N), and the side of the first driving magnetic element 131 facing away from the first driving 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 driving magnetic element 131 facing the first driving coil 14 is blocked, Figure 24 The polarity of the first driving magnetic element 131 facing away from the first driving coil 14 is shown only schematically. Furthermore, there are three first driving coils 14. The three first driving coils 14 are arranged one-to-one with three sets of two opposite polarity directions.

[0333] Please see Figure 24 and combined Figure 23As shown, the first position sensor 194 can be used to detect the first magnetic field change of the first driving magnetic component 131 when the movable carrier 12 moves relative to the fixed carrier 11 along the first direction X. At this time, 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 along the first direction X based on the first magnetic field change.

[0334] Please see Figure 24 and combined Figure 23 As shown, the second position sensor 195 can be used to detect the change in the second magnetic field of the first driving magnetic component 131 when the movable carrier 12 moves relative to the fixed carrier 11 along the first direction X. At this time, 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 along the first direction X based on the change in the second magnetic field.

[0335] It is understandable that, in the process of confirming the displacement of the moving 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 the first position sensor 194 and the second position sensor 195 can be used simultaneously.

[0336] Please see Figure 24 and combined Figure 23 As shown, the first sub-drive coil 151 of the second drive coil 15 faces the second drive magnetic element 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the second direction Y. The first sub-drive coil 151 and the second drive magnetic element 132 of the second drive coil 15 can constitute the second drive mechanism of the anti-shake motor 10.

[0337] It is understood that the first sub-driving coil 151 is positioned facing the second driving magnetic element 132, meaning that the winding plane of the first sub-driving coil 151 faces the second driving magnetic element 132. For example, the winding plane of the first sub-driving coil 151 may be parallel to the XY plane. Exemplarily, the second driving magnetic element 132 may have two opposite polarity directions (…). Figure 24 (As shown by the dashed line with arrows), the polarity direction of the second driving magnetic element 132 is perpendicular to the winding plane of the first sub-driving coil 151. The two sections of the first sub-driving coil 151 can be respectively positioned corresponding to the two polarity directions of the second driving magnetic element 132, and the current in the two sections of the coil (…). Figure 24(As shown by the solid line b with arrows) the flow direction is opposite. The side of the second driving magnetic element 132 facing the first sub-driving coil 151 includes a north pole (N) and a south pole (S), and the side of the second driving magnetic element 132 facing away from the first sub-driving coil 151 correspondingly includes a south pole (S) and a north pole (N). It can be understood that since the polarity of the side of the second driving magnetic element 132 facing away from the first sub-driving coil 151 is blocked, Figure 24 The polarity of the second driving magnetic element 132 facing the first sub-driving coil 151 is shown only schematically. Additionally, Figure 24 The second driving magnetic element 132 is schematically shown to have three polarity directions, with adjacent pairs of polarity directions being opposite. There is one first sub-driving coil 151.

[0338] Please see Figure 24 and combined Figure 23 As shown, the third position sensor 173 can be used to detect the change in the third magnetic field of the second driving magnetic component 132 when the movable carrier 12 moves relative to the fixed carrier 11 along the second direction Y. At this time, 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 along the second direction Y based on the change in the third magnetic field.

[0339] For example, the driving force generated by the first sub-driving coil 151 in cooperation with the second driving magnetic element 132 is less than the driving force generated by the first driving coil 14 in cooperation with the first driving magnetic element 131. In one embodiment, when the number of turns is the same, the number of first sub-driving coils 151 is less than the number of first driving coils 14. And / or, when the number is the same, the number of turns of the first sub-driving coil 151 is less than the number of turns of the first driving coil 14. And / or, the volume of the second driving magnetic element 132 is less than the volume of the first driving magnetic element 131. And / or, when the dimensions are the same, the number of second driving magnetic elements 132 is less than the number of first driving magnetic elements 131.

[0340] Please see Figure 24 and combined Figure 23 As shown, the second sub-drive coil 152 of the second drive coil 15 faces the second drive magnetic element 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. The second sub-drive coil 152 and the second drive magnetic element 132 of the second drive coil 15 can constitute the third drive mechanism of the anti-shake motor 10.

[0341] It is understood that the second sub-driving coil 152 being positioned facing the second driving magnetic element 132 means that the winding plane of the second sub-driving coil 152 faces the second driving magnetic element 132. For example, the winding plane of the second sub-driving coil 152 can be parallel to the XY plane. Exemplarily, there are two second sub-driving coils 152. The two second sub-driving coils 152 can be arranged in the first direction X. The coils in two sections of the two second sub-driving coils 152 can each be positioned corresponding to the two polarity directions of the second driving magnetic element 132, and the current in the coils in the two sections ( Figure 24 The solid line 'c' with an arrow indicates the current in the first second sub-driving coil 152, and the solid line 'd' with an arrow indicates the current in the second second sub-driving coil 152 (the current flows in opposite directions). The side of the second driving magnetic element 132 facing the second sub-driving coil 152 includes a north pole (N) and a south pole (S), and the side of the second driving magnetic element 132 facing away from the second sub-driving coil 152 correspondingly includes a south pole (S) and a north pole (N). The two second sub-driving coils 152 share the two polarity directions of the second driving magnetic element 132. Furthermore, the two second sub-driving coils 152 share the second driving magnetic element 132 with one first sub-driving coil 151.

[0342] It is understandable that by setting two second sub-drive coils 152 in series, the current directions of the two second sub-drive coils 152 are opposite, so that when the two second sub-drive coils 152 are energized, the forces acting on the two second sub-drive coils 152 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 time, the torque exerted by the two second sub-drive coils 152 on the movable carrier 12 allows the movable carrier 12 to rotate relative to the fixed carrier 11.

[0343] It is understood that rotational compensation around the Z-axis is achieved by setting the second sub-drive coil 152 and the second drive magnetic element 132 of the second drive coil 15. 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 for the movable carrier 12 to rotate counterclockwise relative to the fixed carrier 11, thereby achieving rotational compensation of the movable carrier 12 around the Z-axis.

[0344] Please see Figure 24 and combined Figure 23As shown, the first position sensor 194 can be used to detect the first change in the magnetic field of the first driving magnetic component 131 when the movable carrier 12 moves relative to the fixed carrier 11 along the first direction X. The second position sensor 195 can be used to detect the second change in the magnetic field of the first driving magnetic component 131 when the movable carrier 12 moves relative to the fixed carrier 11 along 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.

[0345] In one embodiment, the first position sensor 194, the second position sensor 195, or the anti-shake drive chip 193 can determine the rotation angle of the moving carrier 12 relative to the fixed carrier 11 based on the first magnetic field change and the second magnetic field change.

[0346] Figure 25A yes Figure 22 A partial cross-sectional view of another embodiment of the anti-shake motor 10 shown.

[0347] like Figure 25A As shown, exemplarily, the upper outer shell 30 is fixed to the fixed carrier 11. The upper outer shell 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 outer shell 30 can make the anti-shake motor 10 more aesthetically pleasing and improve its overall integrity. In addition, 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 outer shell 30 can also be used to cover and protect the second driving magnetic component 132.

[0348] like Figure 25A As shown, the upper outer shell 30 can also cover the first through hole 118 of the fixing carrier 11. Figure 3 and Figure 6 The first through hole 118 and the second through hole 119 are illustrated at different angles. Figure 6 The second through hole 119 is shown from different angles.

[0349] Please see Figure 25A and combined Figure 3 As shown, the surface of the upper housing 30 facing away from the second support 122 can be used to form the top surface 10a of the image sensor assembly 101. A portion of the upper housing 30 can, together with the first side plate 113 of the fixing carrier 11, form the first side surface 10b of the image sensor assembly 101. A portion of the upper housing 30 can, together with the second side plate 114 of the fixing carrier 11, form the second side surface 10c of the image sensor assembly 101.

[0350] Figure 25B yes Figure 22A partial cross-sectional view of one embodiment of the anti-shake motor 10 at the CC line.

[0351] Please see Figure 25B and combined Figure 8 As shown, the plurality of extensions 115a of the first metal member 111a of the fixing carrier 11 form magnetic attracting elements. That is, the plurality of extensions 115a of the first metal member 111a of the fixing carrier 11 are made of magnetic attracting material, that is, a material that can generate magnetic attraction with a magnet or other magnetic components, such as ferromagnetic material. In this case, the magnetic attracting element can be part of the metal part of the fixing carrier 11.

[0352] like Figure 25B As shown, the magnetic attracting element 192 is disposed opposite to the extension 115a. A magnetic attraction force can be generated between the magnetic attracting element 192 and the extension 115a. This magnetic attraction force causes the movable carrier 12 to tend to move closer to the fixed carrier 11. In this way, the movable carrier 12 can stably hold the fixed carrier 11 in the Z-axis direction, and the stability of the movable carrier 12 is better when it moves relative to the fixed carrier 11.

[0353] For example, when there are multiple magnetic attracting elements 192 and extensions 115a, the multiple magnetic attracting elements 192 are arranged opposite to the multiple extensions 115a in a one-to-one correspondence.

[0354] For example, the extension 115a is provided facing the magnetic member 192, so that the area of ​​the magnetic member 192 and the extension 115a is relatively large, which is beneficial to increasing the magnetic attraction force between the magnetic member 192 and the extension 115a.

[0355] It is understandable that by reasonably setting the position of the magnetic attraction component 192, the overall magnetic interference of the anti-shake motor 10 can be better avoided and balanced, that is, the magnetic interference between the magnetic attraction component 192 and the driving magnetic component 13 can be minimized.

[0356] It is understandable that the extension 115a of the fixed carrier 11 can provide a smooth contact surface for the rolling element 191 and also serve as a magnetic attractor for the magnetic element 192. The extension 115a of the fixed carrier 11 has a "multi-purpose" function.

[0357] It is understandable that by providing 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 with the fixed carrier 11 and the magnetic attraction centers of the multiple magnetic elements 192 are less likely to change. In this case, the movable carrier 12 exhibits better stability when moving relative to the fixed carrier 11, achieving stable pressing and smooth movement between the movable carrier 12 and the fixed carrier 11.

[0358] Figure 26 yes Figure 5 The diagram shows the structure of the active circuit board 18 from another angle. Figure 27 yes Figure 5 The active circuit board 18 shown is partially exploded in one embodiment.

[0359] like Figure 26 and Figure 27 As shown, the movable circuit board 18 includes a first fixing part 181, an elastic part 182, a second fixing part 183, and an electrical connection part 184. The elastic part 182 is connected between the first fixing part 181 and the second fixing part 183. The electrical connection part 184 is fixed to the first fixing part 181 and electrically connected to the first fixing part 181, and is electrically connected to the outside of the movable circuit board 18 through the elastic part 182 and the second fixing part 183.

[0360] For example, there are two electrical connection portions 184. Each electrical connection portion 184 has a plurality of pin terminals 1841.

[0361] For example, the elastic portion 182 is spiral, zigzag, or curved. This increases the length of the elastic portion 182, thereby significantly reducing its elastic modulus.

[0362] For example, the length of the elastic portion 182 is greater than half the perimeter of the edge of the first fixing portion 181.

[0363] For example, 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 turns.

[0364] For example, the elastic modulus of the active circuit board 18 in the length direction is K. Y K Y The size is in the range of 25 to 35. For example, the elastic modulus of the active circuit board 18 in the length direction is K. Y It can be 30.

[0365] And / or, the elastic modulus of the active 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 modulus of the active circuit board 18 in the length direction is K. X It can be 93.

[0366] For example, the movable circuit board 18 further includes a reinforcing portion 185. The reinforcing portion 185 is fixed to the first fixing portion 181. The reinforcing portion 185 may be a steel plate or other metal plate. The reinforcing portion 185 has a clearance area 1851. The electrical connection portion 184 passes through the clearance area 1851, that is, the reinforcing portion 185 is disposed around the electrical connection portion 184.

[0367] For example, the reinforcing part 185 can be fixed to the first fixing part 181 by adhesive.

[0368] Figure 28 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 9 . Figure 29 yes Figure 28 A partial cross-sectional view of one embodiment of the anti-shake motor 10 at the DD line.

[0369] Please see Figure 28 and Figure 29 and combined Figure 26 and Figure 27 As shown, the movable carrier 12 is fixed to the first fixing part 181 of the movable circuit board 18. It can be understood that the movable carrier 12 may not be connected to the elastic part 182 or the second fixing part 183 of the movable circuit board 18.

[0370] For example, the first support 121 of the active carrier 12 is fixed to the first fixing part 181 by the reinforcing part 185.

[0371] In one embodiment, both the movable carrier 12 and the first fixing part 181 include metal portions, and the metal portion of the movable carrier 12 can be welded to the metal portion of the first fixing part 181.

[0372] Understandably, when the movable carrier 12 moves relative to the fixed carrier 11 along the first direction X, the elastic portion 182 of the movable circuit board 18 deforms along the first direction X. The first fixing portion 181 of the movable circuit board 18 can follow the movable carrier 12 in moving relative to the fixed carrier 11 along the first direction X. When the movable carrier 12 moves relative to the fixed carrier 11 along the second direction Y, the elastic portion 182 of the movable circuit board 18 deforms along the second direction Y. The first fixing portion 181 of the movable circuit board 18 can follow the movable carrier 12 in moving relative to the fixed carrier 11 along the second direction Y.

[0373] In one embodiment, the elastic modulus 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 modulus of the movable circuit board 18 in the length direction is K. Y K Y The size is in the range of 25 to 35. At this time, the K of the active circuit board 18... Y Less than K X .

[0374] Understandably, due to the K of the active circuit board 18 Y Less than K X This limits the travel distance of the movable carrier 12 relative to the fixed carrier 11 in the second direction Y, making it less than the limit on the travel distance of the movable carrier 12 relative to the fixed carrier 11 in the first direction X. In this embodiment, the driving force generated by the first sub-drive coil 151 and the second drive magnetic element 132 can be set to be less than the driving force generated by the first drive coil 14 and the first drive magnetic element 131, thus better matching the K-axis of the movable circuit board 18. Y Less than K X For example, the number of first sub-drive coils 151 and the number of second drive magnetic elements 132 can be reduced, which is beneficial for miniaturization of the anti-shake motor 10.

[0375] Figure 30 yes Figure 4 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 10 .

[0376] Please see Figure 30 and combined Figure 27 As shown, a portion of the electrical connection portion 184 of the movable circuit board 18 passes through the first clearance hole 1214 of the first bracket 121 of the movable carrier 12 (see [reference]). Figure 11 ), and located in the second clearance hole 161 of the first circuit board 16 (see Figure 12 Inside. The pin 1841 of the electrical connection part 184 is electrically connected to the second pin 162 of the first circuit board 16.

[0377] It is understood that the image stabilization drive chip 193 can be electrically connected to the electrical connection part 184 of the movable circuit board 18 via the first circuit board 16, and electrically connected to the outside of the image stabilization motor 10 via the first fixing part 181, the elastic part 182, and the second fixing part 183 of the movable circuit board 18.

[0378] Figure 31 yes Figure 4 An exploded view of one embodiment of the image sensor module 20 shown. Figure 32 yes Figure 4 A partial structural schematic diagram of one embodiment of the image sensor module 20 shown. Figure 33 yes Figure 32 The diagram shows a partial view of the image sensor module 20 from another angle.

[0379] like Figures 31 to 33 As shown, the image sensor module 20 includes a module circuit board 21, an image sensor 22 (also called a sensor), a filter holder 23, and a filter 24. It is understood that the image sensor 22 is also called a photosensitive chip or photosensitive element. The image sensor 22 can be used to capture ambient light passing 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 may include fewer or more structures. For example, the image sensor module 20 may include fewer structures. The image sensor module 20 may also omit 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. These electronic components can be capacitors, inductors, or resistors, etc. These electronic components can be electrically connected to the image sensor 22.

[0380] In some embodiments, the image sensor 22 can be fixed to and electrically connected to the module circuit board 21. In this case, the image sensor 22 and the module circuit board 21 can transmit signals to each other. A 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 has a through hole 231. A filter 24 is fixedly connected to the filter holder 23. The filter 24 can be located within the through hole 231. The filter 24 is also disposed opposite to the image sensor 22. The filter 24 can be used to filter infrared light or blue light, etc., from the light entering the image sensor 22, thereby ensuring that the image sensor 22 has better imaging quality.

[0381] Figure 34 yes Figure 3A partial cross-sectional view of one embodiment of the image sensor assembly 101 at line EE shown. Figure 1 .

[0382] like Figure 34 As shown, the image sensor module 20 is fixed to the first fixing part 181 of the movable circuit board 18. The image sensor module 20 is located on the side of the first fixing part 181 of the movable circuit board 18 away from the reinforcing part 185. It can be understood that the image sensor module 20 may not be connected to the elastic part 182 or the second fixing part 183 of the movable circuit board 18.

[0383] For example, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing part 181 of the movable circuit board 18.

[0384] like Figure 34 As shown, the image sensor module 20 is electrically connected to the first fixing part 181 of the movable circuit board 18. Exemplarily, the image sensor 22 can be electrically connected to the first fixing part 181 of the movable circuit board 18 via the module circuit board 21, and electrically connected to the outside of the image sensor assembly 101 via the elastic part 182 and the second fixing part 183 of the movable circuit board 18.

[0385] Figure 35 yes Figure 3 A partial structural schematic diagram of one embodiment of the image sensor assembly 101 shown. Figure 36 yes Figure 3 A partial cross-sectional view of one embodiment of the image sensor assembly 101 at line EE shown. Figure 2 .

[0386] like Figure 35 and Figure 36 As shown, the image sensor module 20 is located on the side of the movable carrier 12 away from the first fixing part 181 of the movable circuit board 18. At this time, the image sensor module 20 is fixed to the movable carrier 12 by the movable circuit board 18. The image sensor module 20 is located on the side of the movable carrier 12 away from the first drive coil 14.

[0387] Understandably, 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 fixing portion 181 of the movable circuit board 18 can follow the movable carrier 12 to move along the first direction X. When the movable carrier 12 moves relative to the fixed carrier 11 along the second direction Y, the elastic portion 182 of the movable circuit board 18 deforms along the second direction Y. The image sensor module 20 and the first fixing portion 181 of the movable circuit board 18 can follow the movable carrier 12 to move 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 counteract the vibration of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by vibration, thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0388] Furthermore, when the movable carrier 12 rotates clockwise relative to the fixed carrier 11, the movable carrier 12 drives the image sensor module 20 to rotate clockwise via the elastic part 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 movable carrier 12 to rotate counterclockwise relative to the fixed carrier 11 is obtained, thereby achieving rotational compensation of the movable carrier 12 around the Z-axis. At this time, the image sensor module 20 also undergoes rotational compensation around the Z-axis to counteract the jitter stroke caused by the rotation of the camera module 100 around the Z-axis, thereby avoiding or reducing the positional offset of the camera module 100 due to jitter, and thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0389] Figure 37 yes Figure 5 The diagram shows the structure of the first support 121 from another angle.

[0390] like Figure 38 As shown, the first bracket 121 also includes a fixing protrusion 1219. The fixing protrusion 1219 protrudes from the base plate 1211 and is located on the base plate 1211 away from the first protrusion 1212 (see [reference]). Figure 11 The fixing protrusion 1219 is located on one side of the second protrusion 1213. Exemplarily, the fixing protrusion 1219 is a square block. The number of fixing protrusions 1219 is two. In other embodiments, the size, number, and shape of the fixing protrusions 1219 are not specifically limited.

[0391] For example, the two fixing protrusions 1219 may be located on both sides of the first clearance hole 1214.

[0392] Figure 38 yes Figure 3 A partial cross-sectional schematic diagram of one embodiment of the image sensor assembly 101 at the FF line.

[0393] like Figure 37 and Figure 38 As shown, 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. Exemplarily, the module circuit board 21 of the image sensor module 20 is fixedly connected to the fixing bump 1219.

[0394] It is understood that by providing a fixing protrusion 1219 on the base plate 1211 of the first bracket 121, and using the fixing protrusion 1219 to pass through the movable circuit board 18, it is directly fixed to the image sensor module 20. Thus, compared to the scheme where 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 base plate 1211 of the image sensor module 20 and the first bracket 121 can be largely on 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 image sensor module 20 to move, and the movement of the image sensor module 20 is less affected by the movable circuit board 18.

[0395] Figure 39 yes Figure 3 A partial cross-sectional view of one embodiment of the image sensor assembly 101 at line EE shown. Figure 3 .

[0396] like Figure 39 As shown, the fixing carrier 11 is fixed to the second fixing part 183 of the movable circuit board 18. The fixing carrier 11 may not be connected to the first fixing part 181 or the elastic part 182 of the movable circuit board 18. In this way, the connection between the image stabilization motor 10 and the image sensor module 20 is more stable. The overall integrity of the image stabilization motor 10 and the image sensor module 20 is better.

[0397] Figure 40 yes Figure 3 A partial cross-sectional view of one embodiment of the image sensor assembly 101 at line EE shown. Figure 4 .

[0398] like Figure 40As shown, the lower outer shell 40 is fixedly connected to the fixing carrier 11. The lower outer shell 40 can be located on the side of the fixing carrier 11 away from the upper outer shell 30. In this case, the lower outer shell 40 and the upper outer shell 30 can be located on opposite sides of the fixing carrier 11. The lower outer shell 40 can cover at least a portion of the first bracket 121 and its related components. It is understood that the lower outer shell 40 can make the image stabilization motor 10 more aesthetically pleasing and improve its overall appearance.

[0399] For example, the lower housing 40 is also fixedly connected to a second fixing part 183 of the movable circuit board 18. A portion of the movable circuit board 18 may be located between the lower housing 40 and the fixing carrier 11. In this way, the lower housing 40 can also be used to cover a portion of the movable circuit board 18. At this time, the anti-shake motor 10 is more aesthetically pleasing and has a better overall appearance.

[0400] Please see Figure 40 As shown, and in combination Figure 3 As shown, the surface of the lower housing 40 facing away from the fixed carrier 11 can be used to form the bottom surface 10b of the image sensor assembly 101.

[0401] The above text, in conjunction with the accompanying drawings, describes in detail the architecture of an image sensor component 101.

[0402] like Figure 23 and Figure 24 As shown, this application provides a driving architecture for a magnetic coil similar to a "sandwich". Specifically, the driving magnetic component 13 is fixed to the fixed carrier 11, and the first driving coil 14 and the second driving coil 15 are both fixed to the movable carrier 12, with the driving magnetic component 13 located between the first driving coil 14 and the second driving coil 15. It can be understood that, on the one hand, the magnetic field lines on both sides of the driving magnetic component 13 can be fully utilized by the first driving coil 14 and the second driving coil 15. The magnetic field utilization rate of the driving magnetic component 13 is high, which is beneficial to improving the driving stroke of the image stabilization motor 10. On the other hand, compared with the scheme where the first driving coil 14 and the second driving coil 15 are laid flat in the XY plane, the first driving coil 14, the driving magnetic component 13, and the second driving coil 15 of this application are arranged sequentially in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the size in the XY-axis direction. This can greatly improve the space utilization rate in the Z-axis direction, and the increased utilization rate of magnetic field lines can achieve increased thrust, making it possible to apply image stabilization to telephoto modules with more compact space and larger rated stroke requirements.

[0403] like Figure 23 and Figure 24As shown, the driving magnetic component 13 includes a first driving magnetic component 131 and a second driving magnetic component 132. A first driving coil 14 faces the first driving magnetic component 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along a first direction X. A first sub-driving coil 151 of the second driving magnetic component 132 faces the second driving magnetic component 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 along a second direction Y. Thus, the movable carrier 12 can move relative to the fixed carrier 11 along a plane perpendicular to a 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 forces, the movement of the image sensor module 20 in the XY plane can be controlled to counteract the vibration of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by vibration, thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0404] In addition, since the first driving magnetic element 131 and the second driving magnetic element 132 can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane by the first driving magnetic element 131 and the second driving magnetic element 132 will not affect each other, which is conducive to maximizing the number of the first driving magnetic element 131 and the second driving magnetic element 132.

[0405] Understandably, the "pyramid" stacked image stabilization motor architecture of this application has a first sub-drive coil 151 arranged at the top layer and an additional set of symmetrical series reverse coils (second sub-drive coil 152) to achieve rotation compensation and solve the image rotation problem. The middle layer is arranged from top to bottom with a second drive magnetic component 132, a magnetic shielding sheet 111, and a first drive magnetic component 131. The bottom layer of the pyramid is arranged with a first drive coil 14 and an image sensor module 20. The overall combination realizes the image stabilization function of the three-axis decoupled image sensor 22.

[0406] like Figure 23 and Figure 24 As shown, the fixed carrier 11 includes a magnetic shielding sheet 111. A first driving magnetic element 131 is fixed to the first surface 1111 of the magnetic shielding sheet 111, and a second driving magnetic element 132 is fixed to the second surface 1112 of the magnetic shielding sheet 111. In this way, the magnetic shielding sheet 111 can effectively isolate the magnetic field lines crosstalk between the first driving magnetic element 131 and the second driving magnetic element 132, ensuring the utilization rate of the magnetic field lines of the first driving magnetic element 131 and the second driving magnetic element 132.

[0407] like Figure 2 and Figure 3As shown, the image sensor assembly 101 is positioned on the side of the inclined side of the first optical path conversion element 102. This allows the image sensor assembly 101 to effectively utilize the space on the inclined side of the first optical path conversion element 102, improving space utilization. Furthermore, the image sensor assembly 101 and the first optical path conversion element 102 overlap in the thickness direction of the electronic device 1000, making it less likely that the position of the image sensor assembly 101 will increase the thickness of the electronic device 1000.

[0408] like Figure 2 and Figure 3 As shown, by setting the shape of the image sensor assembly 101 to a pyramid-like shape, the volume of the image sensor assembly 101 is significantly reduced to achieve miniaturization. Furthermore, when the image sensor assembly 101 is positioned on the side of the inclined edge of the first optical path conversion element 102, the larger bottom portion of the image sensor assembly 101 can be close to the inclined edge of the first optical path conversion element 102, while the smaller bottom portion can be far away from the inclined edge of the first optical path conversion element 102. This maximizes the use of the empty space on the side of the inclined edge of the first optical path conversion element 102. It is understood that the image sensor assembly 101 of this application can ensure that the volume of the camera module 100 is not significantly increased while maximizing the use of the empty space on the side of the inclined edge of the first optical path conversion element 102, thereby improving the overall space utilization of the telephoto module. Compared to traditional baseplate SOI S, it occupies less module height and length, supporting module space optimization.

[0409] Combination Figure 26 and Figure 27 As shown, this embodiment addresses the problem of limited travel of the movable circuit board 18 due to its large elastic coefficient in the first direction X by providing a larger driving force generated by the cooperation of the first driving coil 14 and the first driving magnetic element 131. For example, a larger driving force in the first direction X can be obtained by providing a larger number of first driving magnetic elements 131 with more magnets and a larger number of first driving coils 14.

[0410] Furthermore, in this embodiment, a first driving magnetic element 131 with a greater number of magnets and a first driving coil 14 with a greater number of magnets are arranged near the bottom of the image sensor assembly 101 to make the best use of the empty space on the side where the inclined edge of the first optical path conversion element 102 is located.

[0411] Combination Figure 26 and Figure 27As shown, this embodiment achieves a smaller driving force by cooperating the first sub-drive coil 151 and the second drive magnetic element 132, in order to match the requirement that the movable circuit board 18 has a smaller elastic coefficient in the second direction Y and a smaller limitation on the movement stroke of the movable circuit board 18. For example, by using fewer first drive magnetic elements 131 with fewer magnets and fewer first drive coils 14, a smaller driving force in the second direction Y can be obtained.

[0412] Furthermore, in this embodiment, a second driving magnetic element 132 with fewer magnets and a second driving coil 15 with fewer magnets are arranged near the top of the image sensor assembly 101 to make the best use of the empty space on the side where the inclined edge of the first optical path conversion element 102 is located.

[0413] like Figure 23 and Figure 24 As shown, the first sub-drive coil 151 of the second drive coil 15 faces the second drive magnetic element 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the second direction Y. The second sub-drive coil 152 of the second drive coil 15 faces the second drive magnetic element 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 element 132, thereby maximizing space utilization.

[0414] Combination Figure 26 and Figure 27 As shown, this application provides a low-K value TSA-rotation compensation design.

[0415] First, by setting the elastic portion 182 of the movable circuit board 18 to a spiral, zigzag, or curved shape, the length of the elastic portion 182 is increased, thereby significantly reducing the elastic coefficient of the elastic portion 182. This reduces the limitation on the movement stroke of the movable circuit board 18, which facilitates the setting of a larger anti-shake stroke for the movable carrier 12. Furthermore, the spiral-shaped, low-K-value elastic portion 182 can effectively compress the dimensions in the X and Y axes while maintaining a small size in the Z-axis direction, reducing crosstalk in XY plane motion and optimizing electromagnetic drive performance and power consumption.

[0416] Furthermore, this embodiment enables rotation compensation by setting the second sub-drive coil 152 to face the second drive magnetic component 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11, thereby suppressing the rotation and crosstalk of the movable circuit board 18.

[0417] Combination Figure 26 and Figure 27As shown, compared to traditional main camera image stabilization solutions, this solution separates the module circuit board 21, movable circuit board 18, first circuit board 16, and image stabilization driver chip 193 of the image sensor module 20 in the Z-axis direction. Furthermore, by providing an electrical connection part 184 on the movable circuit board 18, the image sensor 22 and the image stabilization driver chip 193 are electrically connected, effectively utilizing the Z-axis (optical axis) space and further improving the XY plane space utilization.

[0418] The structure of the image sensor assembly 101 has been described in detail above with reference to the accompanying drawings. The following section will further describe the structure of the image sensor assembly 101 with reference to the accompanying drawings. It is understood that technical content identical to that described above will not be elaborated upon further below.

[0419] Figure 41 yes Figure 2 A schematic diagram of another embodiment of the image sensor assembly 101 shown. Figure 42 yes Figure 41 A partially exploded schematic diagram of one embodiment of the image sensor assembly 101 shown.

[0420] like Figure 41 and Figure 42 As shown, the image sensor assembly 101 includes a stabilization motor 10, an image sensor module 20, and an upper housing 30.

[0421] like Figure 42 As shown, the anti-shake motor 10 includes a fixed carrier 11, a movable carrier 12, a driving magnetic component 13, a first driving coil 14, and a second driving coil 15.

[0422] For example, the active carrier 12 includes a first support 121 and a second support 122.

[0423] For example, the driving magnetic element 13 includes a first driving magnetic element 131, a second driving magnetic element 132, and a third driving magnetic element 133. In other embodiments, the driving magnetic element 13 may not include the second driving magnetic element 132 and / or the third driving magnetic element 133.

[0424] For example, the first driving coil 14 includes a first sub-driving coil 141, a second sub-driving coil 142, and a third sub-driving coil 143. In other embodiments, the first driving coil 14 may not include the second sub-driving coil 142 and / or the third sub-driving coil 143.

[0425] In one embodiment, the first driving coil 14 has one first sub-driving coil 141 and one third sub-driving coil 143. The first driving coil 14 has two second sub-driving coils 142. In other embodiments, the number of the first sub-driving coil 141, the second sub-driving coil 142, and the third sub-driving coil 143 is not specifically limited.

[0426] For example, 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 also exclude the second sub-drive coil 152 and / or the third sub-drive coil 153.

[0427] In one embodiment, the second driving coil 15 has one first sub-driving coil 151 and one third sub-driving coil 153. The second driving coil 15 has two second sub-driving coils 152. In other embodiments, the number of 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 is not specifically limited.

[0428] It is understood that the image stabilization motor 10 may also include more or fewer structures. For example, when the image stabilization motor 10 includes more structures, it may also include a movable circuit board 18 and a roller 191. In other embodiments, the roller 191 may be replaced by a sliding shaft.

[0429] like Figure 42 As shown, exemplarily, 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 the first fixing portion 181 and electrically connected to the first fixing portion 181, and is electrically connected to the outside of the movable circuit board 18 through the elastic portion 182 and the second fixing portion 183.

[0430] like Figure 42 As shown, by way of example, the first bracket 121 includes a base plate 1211, a first protrusion 1212, and a second protrusion 1213. The first protrusion 1212 and the second protrusion 1213 protrude from the same side of the base plate 1211.

[0431] Figure 43 yes Figure 41 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 1 .

[0432] like Figure 42 and Figure 43As shown, the movable carrier 12 is fixed to the first fixing part 181 of the movable circuit board 18. It can be understood that the movable carrier 12 may not be connected to the elastic part 182 or the second fixing part 183 of the movable circuit board 18.

[0433] For example, the base plate 1211 of the first support 121 of the movable carrier 12 is fixed to the first fixing part 181.

[0434] like Figure 43 As shown, 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. Exemplarily, 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 base 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 part 181 of the movable circuit board 18 via a circuit board, and then electrically connected to the external devices of the anti-shake motor 10 via the elastic part 182 and the second fixing part 183 of the movable circuit board 18.

[0435] Figure 44 yes Figure 41 A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 2 .

[0436] like Figure 44 As shown, the fixing carrier 11 is fixed to the second fixing part 183 of the movable circuit board 18. The fixing carrier 11 may not be connected to the first fixing part 181 or the elastic part 182 of the movable circuit board 18.

[0437] like Figure 42 and Figure 44 As shown, the driving magnetic component 13 is fixed to the fixed carrier 11.

[0438] Exemplarily, the fixing carrier 11 is provided with a first through hole 119a, a second through hole 119b, and a third through hole 119c. A first driving magnetic element 131 is located in the first through hole 119a. A second driving magnetic element 132 is located in the second through hole 119b. A third driving magnetic element 133 is located in the third through hole 119c. In one embodiment, there are two second driving magnetic elements 132 and two through holes 119b. The two second driving magnetic elements 132 are disposed in the two second through holes 119b in a one-to-one correspondence.

[0439] Figure 45 yes Figure 41A partial structural diagram of one embodiment of the anti-shake motor 10 shown. Figure 3 .

[0440] like Figure 45 As shown, the second bracket 122 includes a top surface 1221 and a bottom surface 1222 that are disposed opposite to each other.

[0441] like Figure 45 As shown, 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 are all fixed to the movable carrier 12.

[0442] For example, the first sub-drive coil 151, the second sub-drive coil 152 and the third sub-drive coil 15 of the second drive coil 15 are all fixed to the bottom surface 1222 of the second bracket 122.

[0443] For example, the second support 122 is provided with a receiving slot 1223. The opening of the receiving slot 1223 is located on the bottom surface 1222 of the second support 122. The first sub-drive coil 151, the second sub-drive coil 152 and the third sub-drive coil 15 of the second drive coil 15 are all located in the respective receiving slots 1223.

[0445] Please see Figure 46 and combined Figure 43 and Figure 45 As shown, the second bracket 122 is fixedly connected to the first protrusion 1212 and the second protrusion 1213, and is positioned opposite to and spaced apart from the base plate 1211. It can be understood that the connection method between the second bracket 122 and the first protrusion 1212 and the second protrusion 1213 can be found in the above text. Figure 20 and Figure 21 The diagram illustrates the connection method between the second bracket 122 and the first protrusion 1212 and the second protrusion 1213. Specific details will not be elaborated here.

[0447] like Figure 47 and Figure 48 As shown, the driving magnetic component 13 is located between the first driving coil 14 and the second driving coil 15.

[0448] For example, the first driving magnetic element 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. Both 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 face the first driving magnetic element 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. It is understood that the driving methods of the first sub-driving coil 141 of the first driving coil 14 and the first driving magnetic element 131, and the driving methods of the first sub-driving coil 151 of the second driving coil 15 and the first driving magnetic element 131, can be found in [reference needed]. Figure 24 The diagram illustrates the driving method of the first driving coil 14 and the first driving magnetic component 131. Specific details will not be elaborated here.

[0449] For example, the second driving magnetic element 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. Both 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 face the second driving magnetic element 132 to drive the movable carrier to move relative to the fixed carrier 11 along the second direction Y. It is understood that the driving methods of the second sub-driving coil 142 of the first driving coil 14 and the second driving magnetic element 132, and the driving methods of the second sub-driving coil 152 of the second driving coil 15 and the second driving magnetic element 132, can be found in [reference needed]. Figure 24 The diagram illustrates the driving method of the first sub-driving coil 151 and the second driving magnetic element 132. Specific details will not be elaborated here.

[0450] For example, the third driving magnetic element 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 element 133 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. It is understood that the driving methods of the third sub-driving coil 143 of the first driving coil 14 and the third driving magnetic element 133, as well as the driving methods of the third sub-driving coil 153 of the second driving coil 15 and the third driving magnetic element 133, can be found in [reference needed]. Figure 24 The diagram illustrates the driving method of the second sub-driving coil 152 and the second driving magnetic element 132. Specific details will not be elaborated here.

[0451] The above text, in conjunction with the accompanying drawings, describes in detail the architecture of an image sensor component 101.

[0452] like Figure 47 and Figure 48 As shown, this application provides a driving architecture for a magnetic coil similar to a "sandwich". Specifically, the driving magnetic component 13 is fixed to the fixed carrier 11, and the first driving coil 14 and the second driving coil 15 are both fixed to the movable carrier 12, with the driving magnetic component 13 located between the first driving coil 14 and the second driving coil 15. It can be understood that, on the one hand, the magnetic field lines on both sides of the driving magnetic component 13 can be fully utilized by the first driving coil 14 and the second driving coil 15. The magnetic field utilization rate of the driving magnetic component 13 is high, which is beneficial to improving the driving stroke of the image stabilization motor 10. On the other hand, compared with the scheme where the first driving coil 14 and the second driving coil 15 are laid flat in the XY plane, the first driving coil 14, the driving magnetic component 13, and the second driving coil 15 of this application are arranged sequentially in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the size in the XY-axis direction. This can greatly improve the space utilization rate in the Z-axis direction, and the increased utilization rate of magnetic field lines can achieve increased thrust, making it possible to apply image stabilization to telephoto modules with more compact space and larger rated stroke requirements.

[0453] In addition, since the first driving magnetic element 131 and the second driving magnetic element 132 can be arranged along the Z-axis direction, the number of magnets arranged in the XY plane by the first driving magnetic element 131 and the second driving magnetic element 132 will not affect each other, which is conducive to maximizing the number of the first driving magnetic element 131 and the second driving magnetic element 132.

[0454] The structure of the image sensor assembly 101 has been described in detail above with reference to the accompanying drawings. The following section will further describe the structure of the image sensor assembly 101 with reference to the accompanying drawings. It is understood that technical content identical to that described above will not be elaborated upon further below.

[0455] Figure 49 yes Figure 2 A partially exploded schematic diagram of another embodiment of the image sensor assembly 101 shown.

[0456] like Figure 49 As shown, the image sensor assembly 101 includes a stabilization 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 section above on the configuration of the image sensor module 20 and the upper housing 30. Further details will not be elaborated here.

[0457] like Figure 49As shown, the image stabilization motor 10 includes a fixed carrier 11, a movable carrier 12, a driving magnetic component 13, a first driving coil 14, a second driving coil 15, and a movable circuit board 18. The fixed carrier 11, movable carrier 12, driving magnetic component 13, first driving coil 14, second driving coil 15, and movable circuit board 18 can all be found in the various embodiments described above. The difference lies in that the driving magnetic component 13 includes a first driving magnetic component 131 and a second driving magnetic component 132, meaning it does not include a third driving magnetic component 133. The first driving coil 14 includes a first sub-driving coil 141 and a second sub-driving coil 142, meaning it 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, meaning it does not include a third sub-driving coil 153.

[0458] In this embodiment, the movable carrier 12 is movably connected to the fixed carrier 11 via the guide bracket 196, thereby enabling the movable carrier 12 to move relative to the fixed carrier 11 in the XY plane. Specifically:

[0459] like Figure 49 As shown, the anti-shake motor 10 also 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 multiple first support members 197, and to the fixed carrier 11 via multiple 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... Figure 49 The shape shown is rectangular, for example, the shape of guide bracket 196 can also be "L" shaped.

[0460] For example, the guide bracket 196 may be provided with a plurality of first sliding shaft grooves 1964. The plurality of first sliding shaft grooves 1964 are arranged facing the same side of the guide bracket 196. The number of first sliding shaft grooves 1964 may be three, with the three first sliding shaft grooves 1964 respectively located in the first support portion 1961, the second support portion 1962, and the third support portion 1963. The extending direction of the first sliding shaft grooves 1964 may be parallel to the first direction X. The first sliding shaft grooves 1964 may be recessed from one side surface of the corresponding support portion into the interior of the support portion.

[0461] For example, the guide bracket 196 may also be provided with a plurality of second sliding shaft grooves 1965, which are disposed opposite to the plurality of first sliding shaft grooves 1964. The number of second sliding shaft grooves 1965 can be three, located respectively in the first support portion 1961, the second support portion 1962, and the third support portion 1963. The extending direction of the second sliding shaft grooves 1965 can be parallel to the second direction Y. The second sliding shaft grooves 1965 can be recessed from the opposite side surface of the corresponding support portion into the interior of the support portion.

[0462] like Figure 49 As shown, multiple first support members 197 are correspondingly disposed in multiple first sliding shaft grooves 1964. Multiple second support members 198 are correspondingly disposed in multiple second sliding shaft grooves 1965.

[0463] For example, both the first support member 197 and the second support member 198 can be sliding shaft structures.

[0464] Understandably, since the movable carrier 12 is movably connected to the fixed carrier 11 via the guide bracket 196, 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.

[0465] It is understandable that the above description, in conjunction with the accompanying drawings, introduces several structures of the image sensor assembly 101. The following text will further describe several more structures of the image sensor assembly 101.

[0466] For example, in the various embodiments described above, the driving magnetic element 13 is located between the first driving coil 14 and the second driving coil 15. In other embodiments, the positions of the driving magnetic element 13, the first driving coil 14, and the second driving coil 15 can be interchanged.

[0467] For example, in the various embodiments described above, the movable carrier 12 and the fixed carrier 11 are stabilized by magnetic adhesion. In other embodiments, the movable carrier 12 and the fixed carrier 11 may also be stabilized by other methods such as elastic elements.

[0468] For example, in the various embodiments described above, the movable carrier 12 and the fixed carrier 11 are connected via a single rolling element super-slip method. In other embodiments, the movable carrier 12 and the fixed carrier 11 can also be connected via multiple contact methods such as multi-rolling element super-slip / DLC bumps / sliding shafts.

[0469] For example, in the various embodiments described above, the positions of the magnetic attraction element 192 and the magnetic attraction element can be interchanged.

[0470] The structure of the image sensor assembly 101 has been described in detail above with reference to the accompanying drawings. The following section will further describe the structure of the image sensor assembly 101 with reference to the accompanying drawings. It is understood that... Figures 5 to 49 The design of the stabilization motor 10 shown can be directly applied to the structural design of the stabilization motor 50 shown below, provided there is no conflict.

[0471] Figure 50 yes Figure 2 A schematic diagram of another embodiment of the image sensor assembly 101 shown. Figure 51 yes Figure 50 A partially exploded schematic diagram of one embodiment of the image sensor assembly 101 shown.

[0472] like Figure 50 and Figure 51 As shown, the image sensor assembly 101 includes a stabilization motor 50, an image sensor module 20, an upper housing 30, and a lower housing 40. For ease of description, the width direction of the image sensor assembly 101 is defined as the X-axis. The length direction of the image sensor assembly 101 is defined as the Y-axis. The thickness direction of the image sensor assembly 101 is defined as the Z-axis. It can be understood that the coordinate system settings of the image sensor assembly 101 can be flexibly set according to specific practical needs.

[0473] It is understood that the image stabilization 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 shakes in the XY plane due to external forces, the image sensor module 20 can be moved in the XY plane by the image stabilization motor 50 to counteract the shaking stroke of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by shaking. The camera module 100 of this application can control the movement of the image sensor module 20 in the XY plane by the image stabilization motor 50 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0474] Figure 52 yes Figure 51 A partially exploded view of one embodiment of the anti-shake motor 50 shown.

[0475] like Figure 52 As shown, the image stabilization motor 50 includes a fixed carrier 51, a movable carrier 52 (also called a motion carrier), a drive coil 53, a first drive magnetic element 54, and a second drive magnetic element 55. It is understood that... Figure 52The images shown are only schematic representations of some of the components included in the image stabilization motor 50; the actual shape, size, and construction of these components are not subject to change. Figure 52 limited.

[0476] For example, the active carrier 52 includes a first support 521 and a second support 522.

[0477] 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, the number of first drive coils 531 is three. The number of second drive coils 532 is one. The number of third drive coils 533 is two. The number of fourth drive coils 534 is one. In other embodiments, the number of first drive coils 531, second drive coils 532, third drive coils 533, and fourth drive coils 534 is not specifically limited. In other embodiments, the drive coil 53 may also exclude the third drive coil 533 and / or the fourth drive coil 534.

[0478] For example, the number of first driving magnetic elements 54 is two. In other embodiments, the number of first driving magnetic elements 54 is not specifically limited.

[0479] Exemplarily, the second driving magnetic element 55 includes a first sub-driving magnetic element 551 and a second sub-driving magnetic element 552. In one embodiment, the number of first sub-driving magnetic elements 551 is two, and the number of second sub-driving magnetic elements 552 is one. In other embodiments, the number of first sub-driving magnetic elements 551 and second sub-driving magnetic elements 552 is not specifically limited. In other embodiments, the second driving magnetic element 55 may also not include a second sub-driving magnetic element 552.

[0480] It is understood that the image stabilization motor 50 may also include more structures. For example, when the image stabilization motor 50 includes more structures, it may also include a circuit board assembly 56, and / or a movable circuit board 57 (also called a TSA, or flexible circuit board), and / or a connector 581, and / or a magnetic element 582. Exemplarily, the connector 581 may be a single ball, a ball group formed by multiple balls, a sliding shaft, or a protruding structure. The following description will use the example of a ball as the connector 581. Exemplarily, the number of connectors 581 is three. The number of magnetic elements 582 is one. In other embodiments, the number of connectors 581 and magnetic elements 582 is not specifically limited.

[0481] For example, circuit board assembly 56 may include a driver circuit board 561 and a driver chip 562. Circuit board assembly 56 may also include more structures. For example, circuit board assembly 56 may also include a position sensor (not shown), etc.

[0482] Figure 53 yes Figure 52 The diagram shows the structure of the fixed carrier 51 from another angle. Figure 54 yes Figure 52 The diagram shows the structure of the fixed carrier 51 at another angle. Figure 55 yes Figure 52 The diagram shows the structure of the fixed carrier 51 at another angle.

[0483] like Figures 53 to 55 As shown, the fixing carrier 51 includes a top plate 511, a first side plate 512 and a second side plate 513 disposed opposite to each other, and a third side plate 514 and a fourth side plate 515 disposed opposite to each other. The top plate 511 connects the first side plate 512 and the second side plate 513, and also connects the third side plate 514 and the fourth side plate 515. The third side plate 514 and the fourth side plate 515 connect 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 the inner space of the fixing carrier 51.

[0484] For example, the top plate 511 is set at an obtuse angle to the first side plate 512. And / or, the top plate 511 is set at an obtuse angle to the second side plate 513.

[0485] For example, the top plate 511 of the fixing carrier 51 is provided with mounting holes 5111. The mounting holes 5111 connect the inner space of the fixing carrier 51 to the outer space. For example, the number of mounting holes 5111 can be three. 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.

[0486] Understandably, the fixing carrier 51 can be a structural component integrally formed from metal parts and insulating parts through methods such as in-mold injection molding. In this way, the overall strength of the fixing carrier 51 is better.

[0487] like Figure 55As shown, the anti-shake motor 50, by way of example, also includes a magnetic member 59. Exemplarily, the magnetic member 59 may be part of the metal component of the fixing carrier 51. In other embodiments, the magnetic member 59 may also be fixed to the fixing carrier 51 by means of bonding or welding. For example, the magnetic member 59 may be fixed to the surface of the top plate 511 of the fixing carrier 51 facing the inner space of the fixing carrier 51, or it may be embedded within the fixing carrier 51. The magnetic member 59 may be made of a magnetic material, that is, a material capable of generating magnetic attraction with a magnet or other magnetic components, such as a ferromagnetic material.

[0488] Figure 56 yes Figure 52 The circuit board assembly 56 shown is a partial structural schematic diagram of one embodiment.

[0489] like Figure 56 As shown, the motor circuit board 561 includes a mounting portion 5611, a connecting portion 5612, and a pin end portion 5613. The connecting portion 5612 connects the mounting portion 5611 and the pin end portion 5613.

[0490] By way of example, the mounting portion 5611 may be generally flat. The connecting portion 5612 may be generally bent. The pin end 5613 may also be generally flat. By way of example, the plate surface of the pin end 5613 may be perpendicular or substantially perpendicular to the plate surface of the mounting portion 5611.

[0491] 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.

[0492] For example, the mounting part 5611 includes a first surface 5614 and a second surface 5615 arranged along a third direction Z.

[0493] Figure 57 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 1 . Figure 58 yes Figure 57 The diagram shows a partial image stabilization motor 50 at another angle.

[0494] Please see Figure 57 and Figure 58 and combined Figure 52 and Figure 56 As shown, the drive coil 53 is fixed to and electrically connected to the motor circuit board 561. Exemplarily, the drive coil 53 can be fixed to the mounting portion 5611 of the motor circuit board 561.

[0495] 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 a third direction (Z). The first drive coil 531 and the third drive coil 533 can be arranged along a third direction (Z). The first drive coil 531 and the fourth drive coil 534 can be arranged along a third direction (Z). Furthermore, 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 surface space of the first surface 5614 of the mounting part 5611 allows, the third drive coil 533 and the fourth drive coil 534 can also be fixed to the first surface 5614 of the mounting part 5611.

[0496] For example, the number of first drive coils 531 is three. The three first drive coils 531 can be arranged along the first direction X.

[0497] For example, there are multiple third drive coils 533. These multiple third drive coils 533 are located on different sides of the second drive coil 532. For instance, there may be one second drive coil 532 and two third drive coils 533. The two third drive coils 533 can be located on opposite sides of the second drive coil 532 along its length, i.e., the second drive coil 532 is located between the two third drive coils 533. It is 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 described above. Specific details will not be elaborated here.

[0498] Exemplarily, the fourth drive coil 534 may 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 may be arranged along a first direction X. For example, there may be one fourth drive coil 534. The fourth drive coil 534 may be located on the side of the 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.

[0499] like Figure 57 and Figure 58 As shown, the driver chip 562 is fixed to and electrically connected to the motor circuit board 561. Exemplarily, 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 position of the driver chip 562 is not specifically limited. For example, if the board space of 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.

[0500] Understandably, 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 status of the drive coil 53 (e.g., whether current flows or the magnitude of the current when current flows).

[0501] 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 through the motor circuit board 561. The drive chip 562 can control the current status of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 (e.g., whether current is flowing or the magnitude of the current when current is flowing).

[0502] Figure 59 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 2 . Figure 60 yes Figure 59 The diagram shows a partial image stabilization motor 50 at another angle.

[0503] Please see Figure 59 and Figure 60 and combined Figure 57 and Figure 58 As shown, the motor circuit board 561 is fixed to the fixed carrier 51. At this time, the drive coil 53 is fixed to the fixed carrier 51 via the motor circuit board 561.

[0504] Exemplarily, the first surface 5614 of the mounting portion 5611 of the motor circuit board 561 is fixed to the side of the top plate 511 of the fixing carrier 51 away from the inner space of the fixing carrier 51. The pin end 5613 of the motor circuit board 561 is fixed to the side of the second side plate 513 of the fixing carrier 51 away from the inner space of the fixing carrier 51. In this way, the motor circuit board 561 extends from the top plate 511 of the fixing carrier 51 to the second side plate 513 of the fixing carrier 51. It is understood that the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 are located on the side of the top plate 511 of the fixing carrier 51 away from the inner space of the fixing carrier 51. The second drive coil 532, the third drive coil 533, and the fourth drive coil 534 can all be located on the outside of the fixing carrier 51. In addition, the drive chip 562 (see Figure 58 The motor circuit board 561 and the top plate 511 of the fixed carrier 51 can be located between them. The motor circuit board 561 and the top plate 511 of the fixed carrier 51 can also be used to protect the drive chip 562 (see [link]). Figure 58 ).

[0505] Please see Figure 60 and combined Figure 55 and Figure 58 As shown, 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 mounting holes 5111, the multiple first drive coils 531 are arranged one-to-one 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 arranged one-to-one 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.

[0506] 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 chuck 59, and the other first drive coil 531 is located on the other side of the magnetic chuck 59. In this way, the installation positions of the three first drive coils 531 can be avoided from significantly affecting the installation position of the magnetic chuck 59, thereby making the magnetic chuck 59 as close as possible to the center of the fixing carrier 51.

[0507] Please see Figure 60 and combined Figure 55 and Figure 58As shown, exemplarily, the fixed carrier 51 has a plurality of first limiting blocks 516a, which are used to limit the first driving coil 531 to improve the connection stability between the first driving coil 531 and the fixed carrier 51. It is understood that... Figure 55 as well as Figure 60 Only one first limit block 516a is schematically marked.

[0508] Please see Figure 59 and combined Figure 53 , Figure 54 and Figure 57 As shown, exemplarily, the fixed carrier 51 has a plurality of second limiting blocks 516b. The plurality of second limiting blocks 516b can pass through the motor circuit board 561 and are used to limit 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, the fourth drive coil 534 and the fixed carrier 51. It is understood that... Figure 53 , Figure 54 as well as Figure 59 Only one second limit block 516b is schematically marked.

[0509] Figure 61 yes Figure 52 An enlarged schematic diagram of the first support 521 shown in one embodiment.

[0510] like Figure 61 As shown, the first support 521 includes a base plate 5211, a first protrusion 5212, and a second protrusion 5213. The first protrusion 5212 and the second protrusion 5213 protrude from the same side of the base plate 5211. The base plate 5211, the first protrusion 5212, and the second protrusion 5213 enclose the inner space of the first support 521.

[0511] For example, the base plate 5211 is provided with a first mounting groove 5214. The opening of the first mounting groove 5214 is located in the inner space of the first bracket 521. In one embodiment, there are two first mounting grooves 5214. In other embodiments, the number, shape and size of the first mounting grooves 5214 are not specifically limited.

[0512] Exemplarily, the base plate 5211 also provides 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.

[0513] For example, the base plate 5211 is further provided with 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 may be spaced apart from the first mounting groove 5214 and the first recess 5215. The second mounting groove 5216 may be located between the two first mounting grooves 5214.

[0514] For example, the base plate 5211 also has a third mounting groove 5217. The opening of the third mounting groove 5217 is located within the second mounting groove 5216.

[0515] Figure 62 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 3 .

[0516] like Figure 62 As shown, the first driving magnetic component 54 is fixed to the movable carrier 52. In one embodiment, the first driving magnetic component 54 is fixed to the base plate 5211 of the first support 521. The first driving magnetic component 54 can be located in the inner space of the first support 521, that is, between the first protrusion 5212 and the second protrusion 5213.

[0517] For example, the first driving magnetic element 54 can be fixed within the first mounting slot 5214. When there are multiple first driving magnetic elements 54 and multiple first mounting slots 5214, the multiple first driving magnetic elements 54 are disposed one-to-one within the multiple first mounting slots 5214. For example, the number of first driving magnetic elements 54 and the number of first mounting slots 5214 are both two. The two first driving magnetic elements 54 are disposed one-to-one within the two first mounting slots 5214.

[0518] It is understood that the first driving magnetic component 54 may include multiple magnets arranged in the first direction X. The first driving magnetic component 54 can be implemented in various ways. For example, the first driving magnetic component 54 may include at least three magnets. Among the three adjacent magnets, the polarity directions of the two adjacent magnets are opposite. As another example, the first driving magnetic component 54 may adopt a dual-magnet structure, for example, composed of two magnets with opposite polarity directions. As another example, the first driving magnetic component 54 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, while the polarization direction of the magnet located in the middle points from one magnet to another. As another example, the first driving magnetic component 54 may be a Hellbeck magnet array. As yet another example, the first driving magnetic component 54 may adopt a combination array arrangement of multiple sets of Hellbeck magnets, thereby further compressing the magnetic field line distribution, effectively increasing the magnetic thrust, and improving the utilization rate of the magnetic field lines. The structure of the first driving magnetic element 54 can be configured in various ways. This application does not specify a particular configuration. The polarity direction can be from the North Pole (N) towards the South Pole (S), or from the South Pole (S) towards the North Pole (N).

[0519] It is understood that when there is only one first driving magnetic element 54, the structure of the first driving magnetic element 54 can adopt any of the structures described above. When there are multiple first driving magnetic elements 54, the first driving magnetic elements 54 can adopt the same structure, that is, the first driving magnetic elements 54 can adopt any of the structures described above. When there are multiple first driving magnetic elements 54, the first driving magnetic elements 54 can adopt different structures, that is, different first driving magnetic elements 54 can adopt any combination of the structures described above.

[0520] In this embodiment, there are two first driving magnetic components 54. One of the first driving magnetic components 54 uses three magnets. Among the three adjacent magnets, the polarities of two adjacent magnets are opposite. The other first driving magnetic component 54 uses two magnets, and the polarities of the two magnets are opposite.

[0521] like Figure 62 As shown, the connector 581 is disposed on the movable carrier 52. In one embodiment, the connector 581 is disposed within the first groove 5215 of the first bracket 521. When there are multiple connectors 581 and multiple first grooves 5215, the multiple connectors 581 are disposed one-to-one within the multiple first grooves 5215.

[0522] It is understood that when the connector 581 is a ball bearing, the connector 581 can be connected to the movable carrier 52, that is, the connector 581 can move within the first groove 5215. For example, grease can be provided between the connector 581 and the first groove 5215 to reduce the friction between the connector 581 and the movable carrier 52. When the connector 581 is a sliding shaft or a protruding structure, the connector 581 can be fixed to the movable carrier 52.

[0523] like Figure 62 As shown, the magnetic attracting element 582 is fixed to the movable carrier 52. In one embodiment, the magnetic attracting element 582 is fixed within the third mounting slot 5217 of the first bracket 521. When there are multiple magnetic attracting elements 582 and multiple third mounting slots 5217, the multiple magnetic attracting elements 582 are arranged one-to-one within the multiple third mounting slots 5217. It can be understood that by setting both the connecting element 581 and the magnetic attracting element 582 on the first bracket 521, that is, by setting both the connecting element 581 and the magnetic attracting element 582 on the same structural member, the relative positions of the connecting element 581 and the magnetic attracting element 582 are less likely to change significantly when the first bracket 521 undergoes relative movement.

[0524] For example, the magnetic attraction element 582 can be positioned as close as possible to the center of the base plate 5211 of the first bracket 521.

[0525] Figure 63 yes Figure 52 The diagram shows a structural schematic of one embodiment of the second support 522 at different angles.

[0526] like Figure 63 As shown, the second bracket 522 is provided with a fixing groove 5221. Exemplarily, there are two fixing grooves 5221. The two fixing grooves 5221 are arranged at intervals. In other embodiments, the number, size, and shape of the fixing grooves 5221 are not specifically limited.

[0527] Figure 64 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 4 .

[0528] Please see Figure 64 and combined Figure 63 As shown, the second driving magnetic component 55 is fixed to the movable carrier 52. In one embodiment, the second driving magnetic component 55 is fixed in the fixing groove 5221 of the second bracket 522.

[0529] For example, when the second driving magnetic element 55 has two first sub-driving magnetic elements 551 and two fixing slots 5221, the two first sub-driving magnetic elements 551 are fixed in the two fixing slots 5221 in a one-to-one correspondence. When the second driving magnetic element 55 has one second sub-driving magnetic element 552, the second sub-driving magnetic element 552 is fixed in one of the fixing slots 5221. The second sub-driving magnetic element 552 can be located at the end of one of the first sub-driving magnetic elements 551. It is understood that the second sub-driving magnetic element 552 can be disposed in the same layer as the first sub-driving magnetic element 551. In other embodiments, the position between the second sub-driving magnetic element 552 and the first sub-driving magnetic element 551 is not specifically limited.

[0530] It is understood that the first sub-driving magnetic element 551 may include multiple magnets arranged in the second direction Y. The implementation structure of the first sub-driving magnetic element 551 can be varied. For example, the first sub-driving magnetic element 551 may employ a dual-magnet structure, such as consisting of two magnets with opposite polarity directions. Another example is that the first sub-driving magnetic element 551 may include at least three magnets. Among the three adjacent magnets, the polarity directions of the two adjacent magnets are opposite. Yet another example is that the first sub-driving magnetic element 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, while the polarization direction of the magnet located in the middle points from one magnet to another. Yet another example is that the first sub-driving magnetic element 551 may be a Heilbeck magnet array. For example, the first sub-driving magnetic component 551 can adopt a combination array of multiple sets of Hellbeck magnets to further compress the distribution of magnetic field lines, effectively improve the magnetic thrust, and increase the utilization rate of magnetic field lines.

[0531] It is understood that when there is only one first sub-driving magnetic element 551, the structure of the first sub-driving magnetic element 551 can adopt any of the structures described above. When there are multiple first sub-driving magnetic elements 551, the first sub-driving magnetic elements 551 can adopt the same structure, that is, the first sub-driving magnetic elements 551 can adopt any of the structures described above. When there are multiple first sub-driving magnetic elements 551, the first sub-driving magnetic elements 551 can adopt different structures, that is, different first sub-driving magnetic elements 551 can adopt any combination of the structures described above.

[0532] In this embodiment, there are two first sub-driving magnetic elements 551. Both first sub-driving magnetic elements 551 adopt a double magnet structure, for example, composed of two magnets with opposite polarity directions.

[0533] It is understood that the second sub-driving magnetic component 552 may include multiple magnets arranged in the first direction X. For details regarding the specific structure of the second sub-driving magnetic component 552, please refer to the specific structure of the first driving magnetic component 54. Further details will not be elaborated here.

[0534] Figure 65 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 5 .

[0535] Please see Figure 65 and combined Figure 62 and Figure 64 As shown, the second bracket 522 is fixedly connected to the first protrusion 5212 and the second protrusion 5213 of the first bracket 521, and is positioned opposite and spaced apart from the base plate 5211 of the first bracket 521. The first bracket 521 and the second bracket 522 form a movable carrier 52. It can be understood 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 first, and then the second bracket 522 can be fixed to the first bracket 521. This assembly method can reduce the assembly of other structural components with the movable carrier 52.

[0536] For example, the second bracket 522 can be fixedly connected to the first protrusion 5212 and the second protrusion 5213 by adhesive bonding.

[0537] For example, the first protrusion 5212, the second protrusion 5213, and the second bracket 522 all include metal portions. The metal portions of the first protrusion 5212 and the second protrusion 5213 are welded to the metal portion of the second bracket 522.

[0538] For example, the second bracket 522 and the first protrusion 5212 and the second protrusion 5213 can also improve the connection stability between the second bracket 522 and the first bracket 521 through the cooperation of positioning pins.

[0539] Please see Figure 65 and combined Figure 62 and Figure 64 As shown, the first driving magnetic element 54 and the second driving magnetic element 55 can be arranged at intervals and relative to each other.

[0540] Figure 66 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 6 . Figure 67 yes Figure 66 The image shows a partial cross-sectional view of one embodiment of the anti-shake motor 50 at the GG line.

[0541] Please see Figure 66 and Figure 67 and combined Figure 65 As shown, the movable carrier 52 is movably connected to the fixed carrier 51. Exemplarily, the movable carrier 52 can be movably connected to the fixed carrier 51 via a connector 581.

[0542] For example, when the connector 581 is a ball bearing, the connector 581 can be configured to contact the metal portion of the fixed carrier 51. This results in less friction between the connector 581 and the fixed carrier 51, which is beneficial for improving the stable movement of the movable carrier 52 relative to the fixed carrier 51.

[0543] For example, grease is provided between the connector 581 and the first groove 5215. This further reduces the friction between the connector 581 and the fixed carrier 51, thereby better realizing the ball bearing super-lubricating system. In addition, the connector 581 is less likely to detach from the first groove 5215.

[0544] For example, a portion of the top plate 511 of the fixing carrier 51 is located between the bottom plate 5211 of the first support 521 and the second support 522. The portion of the top plate 511 of the fixing carrier 51 and the bottom plate 5211 of the first support 521 may be positioned opposite each other and spaced apart. The portion of the top plate 511 of the fixing carrier 51 and the second support 522 may be positioned opposite each other and spaced apart.

[0545] For example, the base 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 of the fixed carrier 51 and extend to the outer space of the fixed carrier 51. In addition, the second protrusion 5213 of the first bracket 521 (see [link to documentation]) Figure 62 The positional relationship between the first protrusion 5212 of the first bracket 521 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. Specific details will not be elaborated here.

[0546] like Figure 66 and Figure 67 As shown, the magnetic attracting element 582 and the magnetic attracting element 59 are arranged opposite to each other. A magnetic attraction force can be generated between the magnetic attracting element 582 and the magnetic attracting element 59. This magnetic attraction force causes the movable carrier 52 to tend to move closer to the fixed carrier 51, thereby maintaining contact between the fixed carrier 51, the connecting element 581, and the movable carrier 52. In this way, the movable carrier 52 can stably hold the fixed carrier 51 in the Z-axis direction, and the stability of the movable carrier 52 is better when it moves relative to the fixed carrier 51.

[0547] Understandably, by properly positioning the magnetic attraction component 582, the overall magnetic interference of the anti-shake motor 50 can be better avoided and balanced, that is, the interaction between the magnetic attraction component 582 and the first driving magnetic component 54 can be minimized (see [link]). Figure 65 ) and the second driving magnetic element 55 (see Figure 64 Magnetic interference between them.

[0548] It is understandable that by both the connector 581 and the magnetic attracting element 582 are disposed on the movable carrier 52, the relative positions of the connector 581 and the magnetic attracting element 582 are less likely to change significantly when the movable carrier 52 moves relative to the fixed carrier 51. In particular, when there are multiple connectors 581 and multiple magnetic attracting elements 582, the relative positions of the contact centers of the multiple connectors 581 with the fixed carrier 51 and the magnetic attraction centers of the multiple magnetic attracting elements 582 are less likely to change. In this case, the movable carrier 52 has better stability when moving relative to the fixed carrier 51, that is, stable pressing and smooth movement are achieved between the movable carrier 52 and the fixed carrier 51.

[0549] For example, a plurality of the connectors 581 are arranged around the magnetic attracting element 192.

[0550] Figure 68 yes Figure 66 The image shows a partial cross-sectional view of one embodiment of the anti-shake motor 50 at line HH. Figure 69 yes Figure 51 A partially exploded view of one embodiment of the anti-shake motor 50 shown.

[0551] like Figure 68 and Figure 69 As shown, the drive coil 53 is located between the first drive magnetic element 54 and the second drive magnetic element 55. The drive coil 53 faces the first drive magnetic element 54 and the second drive magnetic element 55 to drive the movable carrier 52 to move relative to the fixed carrier 51, thereby achieving optical image stabilization.

[0552] like Figure 68 and Figure 69 As shown, the first driving coil 531 faces the first driving magnetic element 54 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. Exemplarily, there are two first driving magnetic elements 54 and three first driving coils 531. Two of the first driving coils 531 face the same first driving magnetic element 54.

[0553] It is understood that the first driving coil 531 being disposed facing the first driving magnetic element 54 means that the winding plane of the first driving coil 531 faces the first driving magnetic element 54. For example, the winding plane of the first driving coil 531 may be disposed parallel to the XY plane. Exemplarily, the first driving magnetic element 54 may have at least two polarity directions of opposite orientation. Figure 69 The dashed line with an arrow indicates that... Figure 69 A schematic diagram illustrates a first driving magnetic element 54 comprising three polarity directions, wherein adjacent pairs of polarity directions are opposite. Another first driving magnetic element 54 comprises two opposite polarity directions. The polarity directions of the first driving magnetic element 54 can be arranged perpendicular to the winding plane of the first driving coil 531. The coils in two segments of each first driving coil 531 can be respectively arranged corresponding to the two polarity directions of the first driving magnetic element 54, with the current flowing in opposite directions within the two segments. The side of the first driving magnetic element 54 facing the first driving coil 531 includes a south pole (S) and a north pole (N), and the side of the first driving magnetic element 54 facing away from the first driving coil 531 correspondingly includes a north pole (N) and a south pole (S). It is understood that, since the polarity of the side of the first driving magnetic element 54 facing away from the first driving coil 531 is obscured... Figure 69 The polarity of the first driving magnetic element 54 facing the first driving coil 531 is shown only schematically.

[0554] It is understood that, since at least a portion of the first drive coil 531 is located within the mounting hole 5111 of the fixed carrier 51, the fixed carrier 51 no longer separates the first drive coil 531 from the first drive magnetic element 54, thereby allowing the first drive coil 531 to be positioned as close as possible to the first drive magnetic element 54.

[0555] By way of example, the image stabilization 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 moving carrier 52 relative to the fixed carrier 51 along a first direction X.

[0556] Figure 70 yes Figure 66 A partial cross-sectional view of one embodiment of the anti-shake motor 50 shown at line II.

[0557] Please see Figure 70 and combined Figure 68 and Figure 69As shown, the second drive coil 532 faces the first sub-drive magnetic element 551 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the second direction Y. Exemplarily, there is one second drive coil 532 and two first sub-drive magnetic elements 551. One second drive coil 532 simultaneously faces two first sub-drive magnetic elements 551.

[0558] It is understood that the second driving coil 532 being disposed facing the first sub-driving magnetic element 551 means that the winding plane of the second driving coil 532 faces the first sub-driving magnetic element 551. For example, the winding plane of the second driving coil 532 may be disposed parallel to the XY plane. Exemplarily, each first sub-driving magnetic element 551 may include at least two opposite polarity directions (…). Figure 69 (As shown by the dashed line with arrows), the polarity direction of the first sub-driving magnetic element 551 can be perpendicular to the winding plane of the second driving coil 532. The coils of the two sections of the second driving coil 532 can be respectively arranged corresponding to the two polarity directions of the first sub-driving magnetic element 551, and the current flows in opposite directions within the two sections of the coil. For example, the central magnet of one of the first sub-driving magnetic elements 551 simultaneously corresponds to a section of the coil of both second driving coils 532. Furthermore, the side of the first sub-driving magnetic element 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 element 551 facing away from the second driving coil 532 correspondingly includes a south pole (S) and a north pole (N). It is understood that since the polarity of the side of the first sub-driving magnetic element 551 facing the second driving coil 532 is blocked, Figure 69 The polarity of the first sub-driving magnetic element 551 facing the second driving coil 532 is shown only schematically.

[0559] By way of example, the image stabilization 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 moving carrier 52 relative to the fixed carrier 51 along the second direction Y.

[0560] like Figure 68 and Figure 69 As shown, the third driving coil 533 faces the first sub-driving magnetic element 551 of the second driving magnetic element 55 to drive the movable carrier 52 to rotate relative to the fixed carrier 51. Exemplarily, there are two third driving coils 533. The two third driving coils 533 are arranged one-to-one facing the two first sub-driving magnetic elements 551. The arrangement of the third driving coils 533 and the first sub-driving magnetic elements 551 can be found in the arrangement of the second driving coil 532 and the first sub-driving magnetic element 551. Specific details will not be elaborated here.

[0561] It is understandable that by setting two third drive coils 533 in series, the current directions of the two third drive coils 533 are opposite, so that when the two third drive coils 533 are energized, the forces acting on the two third drive coils 533 are opposite. For example, when the first third drive coil 533 is subjected to a force in the positive direction of the Y-axis, the second third drive coil 533 is subjected to a force in the negative direction of the Y-axis. At this time, the torque exerted by the two third drive coils 533 on the movable carrier 52 allows the movable carrier 52 to rotate relative to the fixed carrier 51.

[0562] It is understandable that rotational compensation around the Z-axis is achieved by setting the third drive coil 533 and the first sub-drive magnetic element 551. 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 for the movable carrier 52 to rotate counterclockwise relative to the fixed carrier 51, thereby achieving rotational compensation of the movable carrier 52 around the Z-axis. In addition, since the third drive coil 533 can share the same first sub-drive magnetic element 551 with the second drive coil 532, the structure of the anti-shake motor 50 is simplified, which is beneficial for miniaturizing the anti-shake motor 50.

[0563] It is understood that the third drive coil 533 can share the first sub-drive magnetic component 551 with the second drive coil 532. Therefore, the structure of the anti-shake motor 50 in this embodiment is relatively simple.

[0564] It is understood that the angular change of the movable carrier 52 relative to the fixed carrier 51 can also be detected by a position sensor. For example, by setting a third position sensor and a fourth position sensor, both of which can be fixed to and electrically connected to the motor circuit board 561. The third position sensor can be used to detect the 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 the 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 cooperate to detect the angular change of the movable carrier 12 relative to the fixed carrier 11. For another example, by setting a third position sensor and using it in cooperation with a first position sensor, the angular change of the movable carrier 12 relative to the fixed carrier 11 can be detected. For yet another example, by setting a third position sensor and using it in cooperation with a second position sensor, the angular change of the movable carrier 12 relative to the fixed carrier 11 can be detected.

[0565] like Figure 68 and Figure 69 As shown, the fourth drive coil 534 faces the second sub-drive magnetic element 552 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. Exemplarily, there is one fourth drive coil 534 and one second sub-drive magnetic element 552. The arrangement of the fourth drive coil 534 and the second sub-drive magnetic element 552 can be referred to the arrangement of the first drive coil 531 and the first drive magnetic element 54. Specific details will not be elaborated here.

[0566] It is understandable that, while satisfying the driving force requirement for the movable carrier 52 to move along the second direction Y, and given the space allowable between the second support 522 and the fixed carrier 51, a fourth driving coil 534 can be additionally provided in the layer where the second driving coil 532 is located, and a second sub-driving magnetic element 552 can be additionally provided in the layer where the first sub-driving magnetic element 551 is located. The fourth driving coil 534 and the second sub-driving magnetic element 552 are then used to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. In this case, the fourth driving coil 534 and the second sub-driving magnetic element 552 can cooperate with the first driving coil 531 and the first driving magnetic element 54, thereby significantly increasing the driving force for the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X, which is beneficial for increasing the stroke of the movable carrier 52 relative to the fixed carrier 51 along the first direction X.

[0567] Figure 71 yes Figure 52 An enlarged schematic diagram of one embodiment of the active circuit board 57 shown.

[0568] like Figure 71 As shown, the movable circuit board 57 includes a first fixing part 571, an elastic part 572, and a second fixing part 573. The elastic part 572 is connected between the first fixing part 571 and the second fixing part 573.

[0569] For example, the elastic portion 572 is spiral, zigzag, or curved. This increases the length of the elastic portion 572, thereby significantly reducing its elastic modulus.

[0570] For example, the length of the elastic portion 572 is greater than half the perimeter of the edge of the first fixing portion 571.

[0571] For example, 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 turns.

[0572] For example, the elastic modulus of the active circuit board 57 in the length direction is K.Y K Y The size ranges from 20 to 40. For example, the elastic modulus of the active circuit board 57 in the length direction is K. Y It can be 30.

[0573] And / or, the elastic modulus of the active circuit board 57 in the width direction is K. X K X The size ranges from 70 to 110. For example, the elastic modulus of the active circuit board 57 in the length direction is K. X It can be 93.

[0574] Exemplarily, the movable circuit board 57 also 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 by adhesive. In other embodiments, the movable circuit board 57 may not include the reinforcing portion 574.

[0575] Figure 72 yes Figure 51 A partial structural diagram of one embodiment of the anti-shake motor 50 shown. Figure 7 .

[0576] Please see Figure 72 and combined Figure 71 As shown, the movable carrier 52 is fixed to the first fixing part 571 of the movable circuit board 57. In one embodiment, the movable carrier 52 may not be connected to either the elastic part 572 or the second fixing part 573 of the movable circuit board 57.

[0577] For example, the base plate 5211 of the first support 521 of the movable carrier 52 is fixed to the reinforcing part 574, that is, the movable carrier 52 is fixed to the first fixing part 571 by the reinforcing part 574.

[0578] In one embodiment, both the movable carrier 52 and the first fixing part 571 include metal portions, and the metal portions of the movable carrier 52 can be welded to the metal portions of the first fixing part 571.

[0579] Understandably, when the movable carrier 52 moves along the first direction X, the elastic portion 572 of the movable circuit board 57 deforms along the first direction X. The first fixing portion 571 of the movable circuit board 57 can follow the movable carrier 52 to move along the first direction X. When the movable carrier 52 moves along the second direction Y, the elastic portion 572 of the movable circuit board 57 deforms along the second direction Y. The first fixing portion 571 of the movable circuit board 57 can follow the movable carrier 52 to move along the second direction Y.

[0580] Please see Figure 72 and combined Figure 69 and Figure 71 As shown, in one embodiment, the elastic modulus of the movable circuit board 5718 in the width direction is K. X The elastic modulus of the movable circuit board 5718 in the length direction is K. Y That is, K of active circuit board 5718 Y Less than K X Understandably, this is due to the K of the active circuit board 57. Y Less than K X This limits the travel distance of the movable carrier 52 relative to the fixed carrier 51 in the second direction Y, making it less than the limit on the travel distance of the movable carrier 52 relative to the fixed carrier 51 in the first direction X. In this embodiment, the driving force generated by the second drive coil 532 and the first sub-drive magnetic element 551 can be set to be less than the driving force generated by the first drive coil 531 and the first drive magnetic element 54, thus better matching the K-axis of the movable circuit board 57. Y Less than K X For example, the number of the second drive coil 532 and the first sub-drive magnetic element 551 can be reduced, which is beneficial for miniaturizing the anti-shake motor 50.

[0581] Figure 73 yes Figure 50 A partial structural schematic diagram of one embodiment of the image sensor assembly 101 shown. Figure 74 yes Figure 73 A partial cross-sectional view of one embodiment of the image sensor assembly 101 shown at line JJ.

[0582] like Figures 73 to 74 As shown, the image sensor module 20 includes a module circuit board 21, an image sensor 22 (also called a sensor), a filter holder 23, and a filter 24. For details on the structure of each part of the image sensor module 20, please refer to the various embodiments described above (e.g., Figures 31 to 33 The structure of each part of the image sensor module 20 is described below. Details will not be elaborated here.

[0583] like Figures 73 to 74 As shown, the image sensor module 20 is fixed to the first fixing part 571 of the movable circuit board 57. The image sensor module 20 is located on the side of the first fixing part 571 of the movable circuit board 57 away from the reinforcing part 574. It can be understood that the image sensor module 20 may not be connected to the elastic part 572 or the second fixing part 573 of the movable circuit board 57.

[0584] For example, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing part 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.

[0585] For example, the module circuit board 21 is electrically connected to the first fixing part 571 of the movable circuit board 57 via a soldering process, and then electrically connected to the second fixing part 573 via the elastic part 572 of the movable circuit board 57.

[0586] like Figures 73 to 74 As shown, exemplarily, the image sensor module 20 is located on the side of the first fixing part 571 of the movable circuit board 57 away from the movable carrier 52, that is, the image sensor module 20 is located on the side of the first fixing part 571 of the movable circuit board 57 away from the first driving magnetic member 54. At this time, the image sensor module 20 is fixed to the movable carrier 52 by the movable circuit board 57. Exemplarily, the image sensor module 20 is fixed to the base plate 5211 of the first support 521 of the movable carrier 52 by the first fixing part 571 of the movable circuit board 57.

[0587] Understandably, when the movable carrier 52 moves relative to the fixed carrier 51 along 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 movable carrier 52 in the first direction X. When the movable carrier 52 moves relative to the fixed carrier 51 along 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 movable carrier 52 in the second direction Y. Therefore, the movable carrier 52 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 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 counteract the vibration of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by vibration, thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0588] Furthermore, when the movable carrier 52 rotates clockwise relative to the fixed carrier 51, the movable carrier 52 drives the image sensor module 20 to rotate clockwise via the elastic part 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, a compensating driving force for the movable carrier 52 to rotate counterclockwise relative to the fixed carrier 51 is obtained, thereby achieving rotational compensation of the movable carrier 52 around the Z-axis. At this time, the image sensor module 20 also undergoes rotational compensation around the Z-axis to counteract the jitter stroke caused by the rotation of the camera module 100 around the Z-axis, thereby avoiding or reducing the positional offset of the camera module 100 due to jitter, and thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0589] like Figure 74 As shown, the first bracket 521 also includes a fixing protrusion 5219. The fixing protrusion 5219 protrudes from the base plate 5211 and is located on the side of the base 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 part 571 and the elastic part 572 of the movable circuit board 57 and is fixedly connected to the image sensor module 20.

[0590] It is understood that by providing a fixing protrusion 5219 on the base plate 5211 of the first bracket 521, and using the fixing protrusion 5219 to pass through the movable circuit board 57, it is directly fixedly connected to the image sensor module 20. In this way, compared to the scheme where 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 base plate 5211 of the image sensor module 20 and the first bracket 521 can be largely on the same plane. On the other hand, when the movable carrier 52 moves in the XY plane, the movable carrier 52 can directly drive the image sensor module 20 to move, and the movement of the image sensor module 20 is less affected by the movable circuit board 57.

[0591] like Figure 74 As shown, the fixing carrier 51 is fixed to the second fixing part 573 of the movable circuit board 57. The fixing carrier 51 may not be connected to the first fixing part 571 or the elastic part 572 of the movable circuit board 57. In this way, the overall integrity of the anti-shake motor 10 and the movable circuit board 57 is better.

[0592] like Figure 74 As shown, the motor circuit board 561 is electrically connected to the active circuit board 57. Thus, the driver chip 562 (see [reference]) Figure 58 It can be electrically connected to the active circuit board 57 via the motor circuit board 561, and electrically connected to the outside of the image sensor assembly 101 via the active circuit board 57.

[0593] For example, the pin ends 5613 of the motor circuit board 561 are electrically connected to the second fixing portion 573 of the movable circuit board 57. Thus, the drive chip 562 (see [link to relevant documentation]) Figure 58 The drive coil 53 can be electrically connected to the second fixing part 573 of the movable circuit board 57 via the mounting part 5611, the connecting part 5612, and the pin end 5613 of the motor circuit board 561, and is electrically connected to the outside of the image sensor assembly 101 via the second fixing part 573 of the movable circuit board 57. In other words, the drive coil 53 can be electrically connected to the second fixing part 573 of the movable circuit board 57 via the drive chip 562 and the motor circuit board 561. It is understood that the drive chip 562 in this embodiment (see [link to relevant documentation]) Figure 58 In this embodiment, the motor circuit board 561 is electrically connected to the outside of the image sensor assembly 101, eliminating the need for electrical connection between the motor circuit board 561 and the first fixing part 571 and the elastic part 572 of the movable circuit board 57. The driver chip 562 in this embodiment can be directly electrically connected to the second fixing part 573 of the movable circuit board 57. This method of electrically connecting the driver chip 562 to the outside of the image sensor assembly 101 is simpler and easier to mass-produce. In other embodiments, the electrical connection method and location between the motor circuit board 561 and the movable circuit board 57 are not specifically limited.

[0594] In other embodiments, the driver chip 562 can be directly disposed on the second fixing portion 573 of the movable circuit board 57. The drive coil 53 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 via the motor circuit board 561, and is also electrically connected to the driver chip 562 via the second fixing portion 573 of the movable circuit board 57. In other embodiments, if the image stabilization motor 50 does not include the driver chip 562, the drive coil 53 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 via the motor circuit board 561, and is also electrically connected to the outside of the image stabilization motor 50 via the second fixing portion 573 of the movable circuit board 57.

[0595] Figure 75 yes Figure 50 A partial cross-sectional view of one embodiment of the image sensor assembly 101 shown at line KK.

[0596] like Figure 75As shown, the upper outer shell 30 and the lower outer shell 40 are respectively fixed to both sides of the fixed carrier 51. The upper outer shell 30 and the lower outer shell 40 are assembled and cooperate with the fixed carrier 51 to jointly cover the movable carrier 52 and the internal structure of the anti-shake motor 50 (e.g., drive coil 53, first drive magnetic component 54, second drive magnetic component 55, etc.). The upper outer shell 30 and the lower outer shell 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 cooperation between the upper outer shell 30, the lower outer shell 40 and the fixed carrier 51 makes the anti-shake motor 50 more aesthetically pleasing and with better overall integrity.

[0597] For example, the lower housing 40 also has a light-transmitting hole 40a. The lower housing 40 can also be fixed to the second fixing part 573 of the movable circuit board 57. In this way, on the one hand, the stability of the lower housing 40 can be improved, so that the overall integrity of the image sensor assembly 101 is better. On the other hand, the lower housing 40 can also be used to cover the first fixing part 571, the elastic part 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 disposed opposite to 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.

[0598] For example, the light-transmitting hole 40a of the lower housing 40 can be directly opposite the first light path conversion element 102 (see [link]). Figure 2 The third side 1023 (see also) Figure 2 ).

[0599] The above text, in conjunction with the accompanying drawings, describes in detail the architecture of another image sensor component 101.

[0600] like Figures 68 to 70 As shown, this embodiment provides a driving architecture for a magnetic coil similar to a "sandwich". Specifically, the driving coil 53 is fixed to the fixed carrier 51, and the first driving magnetic component 54 and the second driving magnetic component 55 are both fixed to the movable carrier 52, with the driving coil 53 located between the first driving magnetic component 54 and the second driving magnetic component 55. It can be understood that, compared to the scheme where the first driving magnetic component 54 and the second driving magnetic component 55 are laid flat in the XY plane, the first driving magnetic component 54, the driving coil 53, and the second driving magnetic component 55 of this application are arranged sequentially in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the dimensions in the XY-axis direction, which can greatly improve the space utilization rate in the Z-axis direction.

[0601] It is understood that the first driving coil 531 faces the first driving magnetic component 54 to drive the movable carrier 52 to move relative to the fixed carrier 51 along the first direction X. The second driving coil 532 faces the first sub-driving magnetic component 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 (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 forces, the movement of the image sensor module in the XY plane can be controlled to counteract the vibration of the camera module 100 in the XY plane, thereby avoiding or reducing the positional offset of the camera module 100 caused by vibration, thus achieving optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0602] In addition, since the first driving magnetic element 54 and the second driving magnetic element 55 can be arranged along the Z-axis direction, the number of magnets of the first driving magnetic element 54 and the second driving magnetic element 55 arranged in the XY plane will not affect each other, which is conducive to maximizing the number of the first driving magnetic element 54 and the second driving magnetic element 55.

[0603] It is understandable that, since the drive coil 53 is fixed to the fixed carrier 51, and the first drive magnetic component 54 and the second drive magnetic component 55 are both fixed to the movable carrier 52, the anti-shake motor 50 in this embodiment is a moving magnetic motor. Thus, compared to a moving coil motor, the electrical connection method of the drive coil 53 in this embodiment is simpler.

[0604] It is understandable that the "pyramid" stacked image stabilization motor architecture of this application arranges a second drive coil 532 in the middle layer of the pyramid and adds a set of symmetrical series reverse coils (third drive coil 533) to achieve rotation compensation and solve the image spin problem.

[0605] It is understandable that since the driving coil 53 is located between the first driving magnetic element 54 and the second driving magnetic element 55, and the first driving magnetic element 54 and the second driving magnetic element 55 are far apart, it is beneficial to reduce the crosstalk of the magnetic field lines of the first driving magnetic element 54 and the second driving magnetic element 55, and ensure the utilization rate of the magnetic field lines of the first driving magnetic element 54 and the second driving magnetic element 55.

[0606] Figure 76 yes Figure 52 The diagram shows the arrangement of the second drive coil 532 and the third drive coil 533 in another embodiment.

[0607] like Figure 76As shown, there are multiple third drive coils 533. These 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.

[0608] For example, there is one second drive coil 532. There are two third drive coils 533. The two third drive coils 533 are located on the same side of the second drive coil 532 in the width direction (i.e., the Y-axis direction).

[0609] For example, two third drive coils 533 are arranged sequentially along the first direction X.

[0610] In other embodiments, the arrangement of the third driving coil 533 and the second driving coil 532 is not specifically limited in this application.

[0611] like Figure 76 As shown, multiple third drive coils 533 face the first sub-drive magnetic element 551 to drive the movable carrier 52 to rotate relative to the fixed carrier 51.

[0612] For example, the first sub-driving magnetic element 551 includes at least three polarity directions with opposite directions. Figure 76 (As shown by the dashed line with arrows), adjacent polarity directions are opposite. The polarity direction of the first sub-driving magnetic element 551 can be perpendicular to the winding plane of the second driving coil 532. The coils of two sections of one third driving coil 533 can correspond to the first and second polarity directions of the first sub-driving magnetic element 551, respectively. The coils of two sections of another third driving coil 533 can correspond to the second and third polarity directions of the first sub-driving magnetic element 551, respectively. It can be understood that the central magnet of the first sub-driving magnetic element 551 can be simultaneously positioned opposite to both third driving coils 533. Therefore, the two third driving coils 533 can share the central magnet of the first sub-driving magnetic element 551.

[0613] Understandable, Figure 76 The three polarity directions of the first sub-driving magnetic element 551 are shown only schematically. In other embodiments, the polarity direction of the middle part of the first sub-driving magnetic element 551 can be interchanged with the polarity directions of the two sides.

[0614] It is understood that the image stabilization motor 50 of this embodiment can also be applied to the image sensor assembly 101 mentioned above. Specific details will not be elaborated here.

[0615] It is understood that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0616] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application. The above are merely some embodiments and implementation methods of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
