Description

Technical Field

[0001] This application relates to the field of imaging technologies, and particularly to an anti-shake motor, an image sensor assembly, an imaging module, and an electronic device. Background Art

[0002] With the popularization and development of smart phones, mobile phone photography has become a commonly used shooting method for people. Moreover, mobile phones with optical image stabilization functions are increasingly favored by users. A traditional imaging module includes an image sensor anti-shake motor and an image sensor. The image sensor anti-shake motor controls the movement of the image sensor to achieve anti-shake of the imaging module. A traditional image sensor anti-shake motor generally achieves driving force through the cooperation of a coil and a magnet. However, since only one side of the magnetic induction lines of a traditional magnet is effectively utilized by the driving coil, the utilization rate of the Z-axis magnetic field is low, and the driving stroke of the traditional image sensor anti-shake motor is small. Summary of the Invention

[0003] Embodiments of this application provide an anti-shake motor, an image sensor assembly, an imaging module, and an electronic device, aiming to obtain an anti-shake motor that can improve the utilization rate of magnetic induction lines and achieve a larger rated stroke.

[0004] In a first aspect, an anti-shake motor is provided. The anti-shake motor includes a fixed carrier, a movable carrier, a driving magnetic member, a first driving coil, and a second driving coil. The movable carrier is used to fix the image sensor module;

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

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

[0007] It can be understood that the present application provides a driving architecture for a magnet coil similar to a "sandwich" type. The driving magnetic member is fixed to a fixed carrier, and both the first driving coil and the second driving coil are fixed to a movable carrier. The driving magnetic member is located between the first driving coil and the second driving coil. It can be understood that, on the one hand, the magnetic induction lines on both sides of the driving magnetic member can be fully utilized by the first driving coil and the second driving coil. The magnetic field utilization rate of the driving magnetic member is relatively high, which is beneficial to increasing the driving stroke of the anti-shake motor. On the other hand, compared with the scheme where the first driving coil and the second driving coil are laid flat in the X-Y plane, the first driving coil, the driving magnetic member, and the second driving coil of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction, compressing the dimensions in the XY-axis direction, and can greatly improve the space utilization rate in the Z-axis direction, and improve the magnetic induction line utilization rate to achieve thrust improvement, making it possible to apply anti-shake to a telephoto module with a more compact space and a larger required rated stroke.

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

[0009] In a possible implementation manner, the fixed carrier includes a magnetic isolation sheet, the magnetic isolation sheet includes a first surface and a second surface arranged back to back, the first surface faces the first driving coil, and the second surface faces the second driving coil; the driving magnetic member includes a first driving magnetic member and a second driving magnetic member, the first driving magnetic member is fixed to the first surface, and the second driving magnetic member is fixed to the second surface;

[0010] The first driving coil faces the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along a first direction;

[0011] The second driving coil includes a first sub-driving coil, the first sub-driving coil faces the second driving magnetic member to drive the movable carrier to move relative to the fixed carrier along a second direction, and the second direction is different from the first direction.

[0012] It can be understood that the first driving coil faces the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction X. The first sub-driving coil of the second driving magnetic member faces the second driving magnetic member 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 in a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the camera module collects ambient light, if the electronic device jitters in the X-Y plane due to an external force, the movement of the image sensor module in the X-Y plane can be controlled to cancel the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset caused by the jitter of the camera module, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0013] In addition, the first driving magnetic member is fixed to the first surface of the magnetic isolation sheet, and the second driving magnetic member is fixed to the second surface of the magnetic isolation sheet. In this way, the magnetic isolation sheet can effectively isolate the magnetic induction line crosstalk between the first driving magnetic member and the second driving magnetic member, and ensure the utilization rate of the magnetic induction lines of the first driving magnetic member and the second driving magnetic member.

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

[0015] In a possible implementation manner, the second driving coil includes a second sub-driving coil, and the second sub-driving coil is arranged at an interval from the first sub-driving coil; the second sub-driving coil faces the second driving magnetic member to drive the movable carrier to rotate relative to the fixed carrier.

[0016] It can be understood that by setting the second sub-driving coil to face the second driving magnetic member to drive the movable carrier to rotate relative to the fixed carrier, rotation compensation can be performed. For example, when driving the movable carrier to rotate clockwise relative to the fixed carrier, the movable carrier will drive the image sensor module to rotate clockwise. At this time, by controlling the current direction and magnitude on the second sub-driving coil of the second driving coil, a compensation driving force for the movable carrier to rotate counterclockwise relative to the fixed carrier is obtained, so as to realize the rotation compensation of the movable carrier around the Z-axis direction. At this time, the image sensor module also performs rotation compensation around the Z-axis direction to cancel the jitter stroke generated by the camera module rotating around the Z-axis direction, thereby avoiding or reducing the position offset caused by the jitter of the camera module, and further realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0017] In a possible implementation, the number of the second sub-driving coils is two, and the two second sub-driving coils are connected in series, and the current directions of the two second sub-driving coils are opposite. In this way, when the two second sub-driving coils are powered on, the acting forces received by the two second sub-driving coils are opposite. For example, when the first second sub-driving coil receives an acting force in the positive direction of the Y axis, the second second sub-driving coil receives an acting force in the negative direction of the Y axis. At this time, the torques exerted by the two second sub-driving coils on the movable carrier cause the movable carrier to rotate relative to the fixed carrier.

[0018] In a possible implementation, the anti-shake motor includes a first position sensor, a second position sensor, and a third position sensor, and the first position sensor, the second position sensor, and the third position sensor are all fixedly arranged on the movable carrier at intervals;

[0019] The first position sensor and the second position sensor are used to separately detect the displacement of the movable carrier relative to the fixed carrier in the first direction, and are also used to cooperate with each other to detect the rotation angle of the movable carrier relative to the fixed carrier;

[0020] And / or, the anti-shake motor includes a third position sensor, and the third position sensor is fixedly arranged on the movable carrier, and the third position sensor is used to detect the displacement of the movable carrier relative to the fixed carrier in the second direction.

[0021] In a possible implementation, the movable carrier is movably connected to the fixed carrier through rolling elements. It can be understood that compared with the solution in which the movable carrier is movably connected to the fixed carrier through a guiding bracket, the connection method of this embodiment is simpler and the structure is more simplified, which is beneficial to the miniaturization of the anti-shake motor.

[0022] Exemplarily, the number of the rolling elements is three, and the three rolling elements are distributed at different positions to support the fixed carrier at three points to achieve the stable setting of the anti-shake motor.

[0023] In a possible implementation, the fixed carrier includes a metal part and an insulating part, the metal part is embedded in the insulating part, the metal part includes an extending part, and the extending part is exposed relative to the insulating part; the rolling elements are arranged on the movable carrier and the rolling elements are in contact with the extending part.

[0024] It can be understood that since the extending part of the fixed carrier is made of a metal material, the friction between the rolling elements and the fixed carrier is small, which is beneficial to improving the stable movement of the movable carrier relative to the fixed carrier.

[0025] In a possible implementation, the movable carrier is provided with rolling element grooves. The rolling elements are located in the rolling element grooves. In this way, the rolling elements are not easily disengaged from the movable carrier.

[0026] In a possible implementation, grease is provided between the rolling element and the rolling element groove. In this way, the friction between the rolling element and the fixed carrier can be further reduced, so as to better realize the super-slippery system of the rolling element. In addition, the rolling element is not easily disengaged from the rolling element groove.

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

[0028] It can be understood that the magnetic attraction magnetic part is arranged opposite to the extension part. A magnetic attraction force can be generated between the magnetic attraction magnetic part and the extension part. This magnetic attraction force can make the movable carrier tend to approach the fixed carrier. In this way, the movable carrier can stably hold the fixed carrier in the Z-axis direction, and the stability of the movable carrier is better when the movable carrier moves relative to the fixed carrier.

[0029] It can be understood that the extension part of the fixed carrier can not only provide a smooth contact surface for the rolling element, but also serve as the magnetic attraction part of the magnetic attraction magnetic part. The extension part of the fixed carrier has the function of "serving multiple purposes with one thing".

[0030] It can be understood that by arranging both the rolling element and the magnetic attraction magnetic part on the movable carrier, when the movable carrier moves relative to the fixed carrier, the relative positions of the rolling element and the magnetic attraction magnetic part are not likely to change greatly. In particular, when the numbers of both the rolling element and the magnetic attraction magnetic part are multiple, the relative positions between the contact centers of the multiple rolling elements and the fixed carrier and the magnetic attraction centers of the multiple magnetic attraction magnetic parts are not likely to change. At this time, the stability of the movable carrier is better when the movable carrier moves relative to the fixed carrier, that is, stable pressing and smooth movement between the movable carrier and the fixed carrier are realized.

[0031] In a possible implementation, the movable carrier includes a first bracket and a second bracket; the first bracket includes a bottom plate, a first convex block and a second convex block, the first convex block and the second convex block protrude from the same side of the bottom plate, the second bracket fixedly connects the first convex block and the second convex block, and is arranged opposite to and spaced from the bottom plate;

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

[0033] It can be understood that by setting the movable carrier to be composed of a first bracket and a second bracket, when the second bracket is installed on the first bump and the second bump of the first bracket, the second bracket is opposite to and spaced from the bottom plate, that is, there is an installation space between the second bracket and the bottom plate. At this time, a part of the fixed carrier is arranged between the bottom plate of the first bracket and the second bracket. In this way, when the driving magnetic part is fixed to the fixed carrier and the first driving coil and the second driving coil are both fixed to the movable carrier, the driving magnetic part can be located between the first driving coil and the second driving coil.

[0034] It can be understood that by setting the movable carrier to be composed of a first bracket and a second bracket, it is beneficial to facilitate the assembly of the movable carrier and the fixed carrier.

[0035] In a possible implementation manner, the anti-shake motor further includes a movable circuit board, which includes a first fixing part, an elastic part, and a second fixing part, and the elastic part is connected between the first fixing part and the second fixing part; the bottom plate of the first bracket is fixed to the first fixing part, the fixed carrier is fixed to the second fixing part; the image sensor module is fixed to the side of the first fixing part away from the movable carrier.

[0036] It can be understood that when the movable carrier moves along the first direction X, the elastic part of the movable circuit board deforms along the first direction X. The image sensor module and the first fixing part of the movable circuit board can move along the first direction X following the movable carrier. 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 image sensor module and the first fixing part of the movable circuit board can move along the second direction Y following the movable carrier. Therefore, the movable carrier can control the movement of the image sensor module along the plane perpendicular to the third direction Z (that is, the X-Y plane) through the movable circuit board. When the camera module collects ambient light, if the electronic device jitters in the X-Y plane due to an external force, the movement of the image sensor module in the X-Y plane can be controlled to offset the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0037] In addition, when the movable carrier rotates clockwise relative to the fixed carrier, the movable carrier drives the image sensor module to rotate clockwise through the elastic part of the movable circuit board. In this embodiment, by controlling the current direction and magnitude on the second sub-driving coil of the second driving coil, a compensation driving force for the movable carrier to rotate counterclockwise relative to the fixed carrier is obtained, so as to realize the rotation compensation of the movable carrier in the Z-axis direction. At this time, the image sensor module also performs rotation compensation in the Z-axis direction to offset the jitter stroke generated by the camera module rotating in the Z-axis direction, thereby avoiding or reducing the position offset of the camera module caused by jitter, and further realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0038] Exemplarily, the image sensor module is also electrically connected to the 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 through the module circuit board, and is electrically connected to the outside of the image sensor component through the elastic part and the second fixing part of the movable circuit board.

[0039] In a possible implementation manner, the elastic part is spiral, zigzag or bent. In this way, the length of the elastic part can be increased, so as to greatly reduce the elastic coefficient of the elastic part. The movement stroke of the movable circuit board is less restricted, which is beneficial to realizing the setting of the movable carrier with a large anti-shake stroke. In addition, the elastic part with a low K value in a spiral shape can effectively compress the dimensions in the X and Y axis directions while maintaining a small size in the Z axis direction, reduce crosstalk in the X-Y plane movement, and optimize the electromagnetic driving performance and power consumption performance.

[0040] In a possible implementation manner, the length of the elastic part is greater than half of the perimeter of the edge of the first fixing part. In this way, the length of the elastic part can be increased, so as to greatly reduce the elastic coefficient of the elastic part.

[0041] In a possible implementation manner, the elastic part surrounds at least half of the edge of the first fixing part, or the elastic part surrounds the edge of the first fixing part in multiple turns. In this way, the length of the elastic part can be increased, so as to greatly reduce the elastic coefficient of the elastic part.

[0042] In a possible implementation manner, the elastic coefficient of the movable circuit board in the length direction is K Y , K Y is in the range of 25 to 35; and / or, the elastic coefficient of the movable circuit board in the width direction is K X , K X is in the range of 85 to 100. At this time, the K Y of the movable circuit board is less than K X .

[0043] It can be understood that due to the K of the movable circuit board Y being less than K X , the limitation on the stroke of the movable carrier moving relative to the fixed carrier in the second direction Y is less than the limitation on the stroke of the movable carrier moving relative to the fixed carrier in the first direction X. At this time, in this embodiment, the driving force generated by the first sub-driving coil and the second driving magnetic member can be set to be less than the driving force generated by the first driving coil and the first driving magnetic member, so as to better match the K of the movable circuit board Y being less than K X . For example, the number of the first sub-driving coils and the number of the second driving magnetic members can be set to be relatively small, which is beneficial to the miniaturization of the anti-shake motor.

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

[0045] In a possible implementation manner, the first bracket further includes a fixing bump, and the fixing bump protrudes from the bottom plate and is located on the side of the bottom plate away from the first bump and / or the second bump; the fixing bump passes through the gap of the elastic portion and is fixedly connected to the image sensor module.

[0046] It can be understood that by protruding a fixing bump on the bottom plate of the first bracket and using the fixing bump to pass through the movable circuit board and directly fixedly connecting to the image sensor module. In this way, compared with the solution in which the image sensor module is fixedly connected to the first bracket through 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 bottom plate of the image sensor module and the first bracket can be in the same plane to a greater extent. On the other hand, when the movable carrier moves in the X-Y 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 a possible implementation manner, the anti-shake motor includes a first circuit board and an anti-shake driving chip; the first circuit board is fixed to the bottom plate of the first bracket; the first driving coil and the anti-shake driving chip are both fixed to the first circuit board, and the input end and the output end of the first driving coil form a current loop through the first circuit board and the anti-shake driving chip.

[0048] In a possible implementation, the bottom plate of the first bracket is provided with a first avoidance hole, and the first circuit board is provided with a second avoidance hole. The first avoidance hole and the second avoidance hole are arranged opposite to each other; the movable circuit board includes an electrical connection part, the electrical connection part is fixed to the first fixing part, a part of the electrical connection part passes through the first avoidance hole and is located in the second avoidance hole, and the pin end of the electrical connection part is electrically connected to the second pin end of the first circuit board; the anti-shake 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] It can be understood that, compared with the traditional main camera anti-shake solution, the separation design of the image sensor module, the movable circuit board, the first circuit board, and the anti-shake driving chip in the Z-axis direction in this implementation, and by arranging the electrical connection part on the movable circuit board, the electrical connection between the image sensor and the anti-shake driving chip is realized, effectively utilizing the Z-axis space and further improving the utilization rate of the X-Y plane space.

[0050] In a possible implementation, the anti-shake motor includes a second circuit board, the second circuit board is fixed to the second bracket, and the second driving coil is fixed to the second circuit board; the second driving coil forms a current loop with the anti-shake driving chip through the second circuit board, the conductive part in the movable carrier, and the first circuit board. In this way, the electrical connection path between the second driving coil and the anti-shake driving chip is relatively simple.

[0051] In a possible implementation, the fixed carrier includes a top plate, a first side plate and a second side plate arranged opposite to each other, and the top plate is connected between the first side plate and the second side plate;

[0052] The top plate and the first side plate are arranged at an obtuse angle, and / or the top plate and the second side plate are arranged at an obtuse angle;

[0053] At least part of the top plate forms a magnetic isolation sheet. The first surface of the magnetic isolation sheet is the surface of the top plate facing the inside of the fixed carrier, and the second surface of the magnetic isolation sheet is the surface of the top plate facing away from the outside of the fixed carrier.

[0054] It can be understood that by arranging the top plate and the first side plate at an obtuse angle, and / or the top plate and the second side plate at an obtuse angle, the fixed carrier is roughly in a "pyramid" shape. At this time, the second driving coil is arranged on one side of the top plate of the fixed carrier, the first driving magnetic part and the second driving magnetic part are arranged on the top plate of the fixed carrier, and the second driving coil is located at the bottom side of the fixed carrier. In this way, in this implementation, the anti-shake motor has a "pyramid" stacked structure, the second driving coil is arranged at the top layer of the pyramid, the first driving magnetic part and the second driving magnetic part are arranged from top to bottom in the middle layer, and the first driving coil is arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupled image sensor.

[0055] In a possible implementation, the anti-shake motor further includes a guiding bracket, and the guiding bracket includes a first supporting portion, a second supporting portion, and a third supporting portion;

[0056] The first supporting portion, the second supporting portion, and the third supporting portion are connected to the first bracket of the movable carrier through a plurality of first supporting members and are connected to the fixed carrier through a plurality of second supporting members, so that the relative movement direction between the movable carrier and the guiding bracket is different from the relative movement direction between the guiding bracket and the fixed carrier.

[0057] It can be understood that the movable carrier is movably connected to the fixed carrier through the guiding bracket, and it is not easy for the movable carrier to rotate relative to the fixed carrier. The movement mode of the movable carrier is more stable.

[0058] In a possible implementation,

[0059] The driving magnetic members include a first driving magnetic member and a second driving magnetic member; the first driving coil includes a first sub-driving coil and a second sub-driving coil; the second driving coil includes a first sub-driving coil and a second sub-driving coil; the first driving magnetic member is located between the first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil, and the second driving magnetic member is located between the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil;

[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 member to drive the movable carrier to move relative to the fixed carrier along a 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 member to drive the movable carrier to move relative to the fixed carrier along a second direction, and the second direction is different from the first direction.

[0062] It can be understood that by setting the first driving magnetic member between the first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil, the magnetic induction lines on both sides of the first driving magnetic member can be fully utilized by the first sub-driving coil of the first driving coil and the first sub-driving coil of the second driving coil. The magnetic field utilization rate of the first driving magnetic member is relatively high, which is beneficial to increasing the driving stroke of the anti-shake motor.

[0063] It can be understood that by setting the second driving magnetic member between the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil, the magnetic induction lines on both sides of the second driving magnetic member can be fully utilized by the second sub-driving coil of the first driving coil and the second sub-driving coil of the second driving coil. The magnetic field utilization rate of the second driving magnetic member is relatively high, which is beneficial to increasing the driving stroke of the anti-shake motor.

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

[0065] In a possible implementation, the driving magnetic member includes a third driving magnetic member; the first driving coil includes a third sub-driving coil, the second driving coil includes a third sub-driving coil, and the third driving magnetic member is located between the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil; the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil face the third driving magnetic member to drive the movable carrier to rotate relative to the fixed carrier.

[0066] It can be understood that by arranging the third driving magnetic member between the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil, the magnetic induction lines on both sides of the third driving magnetic member can be fully utilized by the third sub-driving coil of the first driving coil and the third sub-driving coil of the second driving coil. The magnetic field utilization rate of the third driving magnetic member is relatively high, which is beneficial to increasing the driving stroke of the anti-shake motor.

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

[0068] In a second aspect, an anti-shake motor is provided. The anti-shake motor includes a fixed carrier, a movable carrier, a driving coil, a first driving magnetic member, and a second driving magnetic member. The movable carrier is used to fix the image sensor module; the driving coil is fixed to the fixed carrier, the first driving magnetic member and the second driving magnetic member are both fixed to the movable carrier, and the driving coil is located between the first driving magnetic member and the second driving magnetic member;

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

[0070] It can be understood that this embodiment provides a driving architecture of a magnet coil similar to a "sandwich" type. Specifically, the driving coil is fixed to the fixed carrier, the first driving magnetic member and the second driving magnetic member are both fixed to the movable carrier, and the driving coil is located between the first driving magnetic member and the second driving magnetic member. Compared with the scheme in which the first driving magnetic member and the second driving magnetic member are tiled in the X-Y plane, the first driving magnetic member, the driving coil, and the second driving magnetic member of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction and compressing the dimensions in the XY-axis direction, which can greatly improve the space utilization rate in the Z-axis direction.

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

[0072] It can be understood that since the driving coil is fixed to the fixed carrier, and the first driving magnetic member and the second driving magnetic member are both fixed to the movable carrier, the anti-shake motor of this embodiment is a moving magnet motor. In this way, compared with the moving coil motor, the electrical connection method of the driving coil in this embodiment is simpler.

[0073] It can be understood that since the driving coil is located between the first driving magnetic member and the second driving magnetic member, and the first driving magnetic member and the second driving magnetic member are spaced far apart, it is beneficial to reduce the magnetic induction line crosstalk between the first driving magnetic member and the second driving magnetic member and ensure the utilization rate of the magnetic induction lines of the first driving magnetic member and the second driving magnetic member.

[0074] In a possible implementation manner, the driving coil includes a first driving coil and a second driving coil, and the second driving magnetic member includes a first sub-driving magnetic member; the first driving coil faces the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along a first direction; the second driving coil faces the first sub-driving magnetic member to drive the movable carrier to move relative to the fixed carrier along a second direction, and the second direction is different from the first direction.

[0075] It can be understood that the first driving coil faces the first driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction X. The second driving coil faces the first sub-driving magnetic member 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 X-Y plane). When the camera module collects ambient light, if the electronic device jitters in the X-Y plane due to an external force, the movement of the image sensor module in the X-Y plane can be controlled to offset the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

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

[0077] Compared with the solution where the first driving coil and the second driving coil are tiled in the X-Y plane, the first driving coil and the second driving coil of the present application are arranged along the third direction, which can further utilize the space in the Z-axis direction, further compress the dimensions in the XY-axis direction, and can greatly improve the space utilization rate in the Z-axis direction.

[0078] In a 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 is fixed to the first surface of the motor circuit board, and a second drive coil is fixed to the second surface of the motor circuit board.

[0079] In a possible implementation, the fixed carrier is provided with a mounting hole, and the mounting hole communicates with the inner space of the fixed carrier; at least a part of the first drive coil is located in the mounting hole. In this way, on the one hand, the fixed carrier no longer separates the first drive coil and the first drive magnetic member, so that the first drive coil can be arranged as close as possible to the first drive magnetic member. On the other hand, in the Z-axis direction, the first drive coil and the fixed carrier have an overlapping area, so that the size in the Z-axis direction can be compressed.

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

[0081] It can be understood that by setting the third drive coil and the first sub-drive magnetic member, rotational compensation in the Z-axis direction is achieved. For example, when the movable carrier rotates clockwise relative to the fixed carrier, the current direction and magnitude on the second sub-drive coil of the second drive coil can be controlled to obtain a compensation driving force for the movable carrier to rotate counterclockwise relative to the fixed carrier, so as to achieve rotational compensation of the movable carrier in the Z-axis direction. In addition, since the third drive coil and the second drive coil can share the same first sub-drive magnetic member, the structure of the anti-shake motor is simplified, which is beneficial to the miniaturization of the anti-shake motor.

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

[0083] In a possible implementation, the number of the third drive coils is multiple; the multiple third drive coils are located on both sides of the second drive coil in the length direction, or the multiple third drive coils are located on the same side of the second drive coil in the width direction. In this way, the arrangement between the third drive coil and the second drive coil is more compact.

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

[0085] The second driving magnetic member includes a second sub-driving magnetic member, and the second sub-driving magnetic member is arranged on the same layer as the first sub-driving magnetic member; the fourth driving coil faces the second sub-driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction.

[0086] It can be understood that by additionally arranging the fourth driving coil in the layer where the second driving coil is located, and additionally arranging the second sub-driving magnetic member in the layer where the first sub-driving magnetic member is located, and using the fourth driving coil and the second sub-driving magnetic member to drive the movable carrier to move relative to the fixed carrier along the first direction X. At this time, the fourth driving coil and the second sub-driving magnetic member can cooperate with the first driving coil and the first driving magnetic member, so as to greatly improve the driving force for the movable carrier to move relative to the fixed carrier along the first direction X, which is beneficial to increasing the stroke of the movable carrier moving relative to the fixed carrier along the first direction X.

[0087] In a possible implementation manner, the movable carrier includes a first bracket and a second bracket;

[0088] The first bracket includes a bottom plate, a first bump and a second bump. The first bump and the second bump protrude from the same side of the bottom plate. The second bracket is fixedly connected to the first bump and the second bump and is arranged opposite to and spaced from the bottom plate. At least part of the fixed carrier is located between the bottom plate and the second bracket; the first driving magnetic member is fixed to the bottom plate, and the second driving magnetic member is fixed to the second bracket.

[0089] It can be understood that since the movable carrier can be formed by assembling the first bracket and the second bracket, when the movable carrier is assembled with other structural parts, the first bracket and the second bracket can be first assembled with other structural parts, and then the second bracket can be fixed to the first bracket. This assembly method can reduce the assembly of other structural parts and the movable carrier.

[0090] In a possible implementation manner, the movable carrier is movably connected to the fixed carrier through a connecting member.

[0091] In a possible implementation manner, the number of the connecting members is three, and the three connecting members are distributed at different positions to support the fixed carrier at three points to realize the stable setting of the anti-shake motor.

[0092] In a possible implementation manner, the movable carrier is provided with a first groove. The connecting member is located in the first groove. In this way, the connecting member is not easily disengaged from the movable carrier.

[0093] In a possible implementation manner, a grease is provided between the connecting member and the first groove. In this way, the friction between the connecting member and the fixed carrier can be further reduced, so as to better realize the super-slippery system of the connecting member. In addition, the connecting member is not easily disengaged from the first groove.

[0094] In a possible implementation, the fixed carrier has a magnetic attracting member, and the movable carrier is provided with a magnetic attracting magnetic member. The magnetic attraction force between the magnetic attracting magnetic member and the magnetic attracting member enables the fixed carrier, the connecting member, and the movable carrier to remain in contact with each other.

[0095] It can be understood that the magnetic attracting magnetic member and the magnetic attracting member are arranged opposite to each other. A magnetic attraction force can be generated between the magnetic attracting magnetic member and the magnetic attracting member. This magnetic attraction force can make the movable carrier tend to approach the fixed carrier, so that the fixed carrier, the connecting member, and the movable carrier remain in contact with each other. In this way, the movable carrier can stably attract the fixed carrier in the Z-axis direction, and when the movable carrier moves relative to the fixed carrier, the stability of the movable carrier is better.

[0096] In a possible implementation, the magnetic attracting member is a part of the fixed carrier.

[0097] In a possible implementation, there are multiple connecting members, and the multiple connecting members are arranged around the magnetic attracting magnetic member. In this way, when the movable carrier moves relative to the fixed carrier, the stability of the movable carrier is better.

[0098] In a possible implementation, the anti-shake motor further includes a movable circuit board. The movable circuit board includes a first fixing portion, an elastic portion, and a second fixing portion. The elastic portion is connected between the first fixing portion and the second fixing portion; the movable carrier is fixed to the first fixing portion, and the fixed carrier is fixed to the second fixing portion; the image sensor module is fixed to the side of the first fixing portion away from the movable carrier.

[0099] It can be understood that when the movable carrier moves relative to the fixed carrier along the first direction X, the elastic portion of the movable circuit board deforms along the first direction X. The image sensor module and the first fixing portion of the movable circuit board can follow the movable carrier and move along the first direction X. When the movable carrier moves relative to the fixed carrier along the second direction Y, the elastic portion of the movable circuit board deforms along the second direction Y. The image sensor module and the first fixing portion of the movable circuit board can follow the movable carrier and move along the second direction Y. Therefore, the movable carrier can control the image sensor module to move in a plane perpendicular to the third direction Z (i.e., the X-Y plane) through the movable circuit board. When the camera module collects ambient light, if the electronic device jitters in the X-Y plane due to an external force, the movement of the image sensor module in the X-Y plane can be controlled to offset the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0100] In a possible implementation, the elastic part is in a spiral shape, a broken line shape or a bent shape. In this way, the length of the elastic part can be increased, thereby greatly reducing the elastic coefficient of the elastic part. The movement stroke of the movable circuit board is less restricted, which is beneficial to setting the movable carrier to have a larger anti-shake stroke. In addition, the elastic part with a spiral shape and a low K value can effectively compress the dimensions in the X and Y axis directions while maintaining a small size in the Z axis direction, reduce crosstalk in the X-Y plane movement, and optimize the electromagnetic drive performance and power consumption performance.

[0101] In a possible implementation, the length of the elastic part is greater than half of the perimeter of the edge of the first fixing part. In this way, the length of the elastic part can be increased, thereby greatly reducing the elastic coefficient of the elastic part.

[0102] In a possible implementation, the elastic part surrounds at least half of the edge of the first fixing part, or the elastic part surrounds the edge of the first fixing part in multiple turns. In this way, the length of the elastic part can be increased, thereby greatly reducing the elastic coefficient of the elastic part.

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

[0104] In a possible implementation, the first bracket further includes a fixing bump, the fixing bump protrudes from the bottom plate and is located on the side of the bottom plate away from the first bump and / or the second bump; the fixing bump 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 bottom plate of the image sensor module and the first bracket can be largely in the same plane. On the other hand, when the movable carrier moves in the X-Y 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 a possible implementation, the drive coil is electrically connected to the second fixing part of the movable circuit board through the motor circuit board.

[0106] It can be understood that in the solution where the drive coil of the present embodiment is electrically connected to the outside of the image sensor assembly, the motor circuit board does not need to be electrically connected to the first fixing part and the elastic part of the movable circuit board anymore. The drive chip of the present embodiment can be directly electrically connected to the second fixing part 3 of the movable circuit board. The solution of electrically connecting the drive chip to the outside of the image sensor assembly is relatively simple and easier to mass-produce.

[0107] In a possible implementation, the anti-shake motor includes a driving chip. The driving chip is fixed to the motor circuit board and electrically connected to the motor circuit board. The input end and the output end of the driving coil form a current loop through the motor circuit board and the driving chip.

[0108] In a possible implementation, the fixed carrier includes a top plate, a first side plate and a second side plate which are oppositely arranged, and the top plate is connected between the first side plate and the second side plate;

[0109] The top plate and the first side plate are arranged at an obtuse angle, and / or the top plate and the second side plate are arranged at an obtuse angle;

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

[0111] It can be understood that by setting the top plate and the first side plate at an obtuse angle, and / or the top plate and the second side plate at an obtuse angle, the fixed carrier is roughly in a "pyramid" shape. At this time, the first driving magnetic member is arranged on one side of the top plate of the fixed carrier, the driving coil is arranged on the top plate of the fixed carrier, and the second driving magnetic member is located at the bottom side of the fixed carrier. In this way, in this implementation, the anti-shake motor has a "pyramid" stacked structure, with the second driving magnetic member arranged at the top layer of the pyramid, the first driving coil, the second driving coil, the third driving coil and the fourth driving coil arranged from top to bottom in the middle layer, and the first driving magnetic member arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupled image sensor.

[0112] In a third aspect, an image sensor assembly is provided. The image sensor assembly includes an image sensor module and the anti-shake motor as described in the first aspect above, and the image sensor module is fixed to the movable carrier. Alternatively, the image sensor assembly includes an image sensor module and the anti-shake motor as described in the second aspect above, and the image sensor module is fixed to the movable carrier.

[0113] It can be understood that when the movable carrier moves along the first direction X, the image sensor module can move along the first direction X following the movable carrier. When the movable carrier moves relative to the fixed carrier along the second direction Y, the image sensor module can move along the second direction Y following the movable carrier. Therefore, the movable carrier can control the movement of the image sensor module in a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the image sensor assembly is applied to a camera module, if the camera module jitters in the X-Y plane, the movement of the image sensor module in the X-Y plane can be controlled to cancel the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0114] In addition, when the movable carrier rotates clockwise relative to the fixed carrier, the movable carrier drives the image sensor module to rotate clockwise. In this embodiment, by controlling the direction and magnitude of the current on the second sub-driving coil of the second driving coil, a compensation driving force for the counterclockwise rotation of the movable carrier relative to the fixed carrier is obtained, so as to realize the rotational compensation of the movable carrier in the Z-axis direction. At this time, the image sensor module also performs rotational compensation in the Z-axis direction to offset the jitter stroke generated by the rotation of the camera module in the Z-axis direction, thereby avoiding or reducing the position offset of the camera module caused by jitter, and further realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0115] In a possible implementation manner, the image sensor module is fixed on the side of the movable carrier away from the first driving coil. In this way, the image sensor module is not easily interfered with by the anti-shake motor;

[0116] Or the image sensor module is fixed on the side of the movable carrier away from the first driving magnetic part. In this way, the image sensor module is not easily interfered with by the anti-shake motor

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

[0118] It can be understood that if the camera module jitters in the X-Y plane, the anti-shake motor can control the movement of the image sensor module in the X-Y plane to offset the jitter stroke generated by the camera module in the X-Y plane, so as to avoid or reduce the position offset of the camera module caused by jitter, thereby realizing the optical image stabilization of the camera module and improving the imaging quality of the camera module.

[0119] In a possible implementation manner, 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 a possible implementation manner, the first optical path conversion element includes a first side surface, a second side surface, and a third side surface that are connected to each other. After the light passes through the first optical element, it enters the first optical path conversion element, and then is totally reflected by the second side surface of the first optical path conversion element and reflected by the third side surface of the first optical path conversion element, and then propagates to the image sensor assembly;

[0121] The image sensor assembly is located on the side where the third side of the first optical path conversion element is located. In this way, on the one hand, the image sensor assembly can effectively utilize the space where the third side of the first optical path conversion element is located; 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 is not likely to increase the thickness of the electronic device.

[0122] In a possible implementation, the first side and the second side of the first optical path conversion element are perpendicular to each other, and the third side of the first optical path conversion element is an inclined surface.

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

[0124] In a fifth aspect, an electronic device is provided. The electronic device includes a device housing and the camera module as described above, and the camera module is disposed in the device housing. It can be understood that the camera module of the electronic device in this implementation has an anti-shake motor with a larger rated stroke. Description of the Drawings

[0202] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0203] Object side: Taking the lens as the boundary, the side where the object to be photographed is located is the object side, and the surface of the lens close to the object side is called the object side surface;

[0204] Image side: Taking the lens as the boundary, the side where the image of the object to be photographed is located is the image side, and the surface of the lens close to the image side is called the image side surface;

[0205] The optical axis is an axis that vertically passes through the center of the lens. The lens optical axis is the axis passing through the centers of all the lenses of the lens. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens should be such that all the light rays converge at a point behind the lens. This point where all the light rays converge is the focal point.

[0206] Sensor shift optical image stabilizer (SOI S);

[0207] Trace suspension assembly (TSA);

[0208] Moving tilt: The dynamic tilt (tilting about the x-axis or y-axis) of the moving platform that characterizes the motion stability of the SOI S;

[0209] ShiftZ: The displacement fluctuation of the moving platform in the Z-direction (optical axis direction) of the SOI S that characterizes the motion stability of the SOI S.

[0210] In the description of this application, it should be noted that unless otherwise specified and limited, the terms "installed", "connected", "joined", and "connected to" should be understood in a broad sense. For example, "connected" 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. Among them, "fixed connection" means that the two are connected and the relative positional relationship after connection remains unchanged. "Movable connection" means that the two are connected and can move relative to each other after connection, and the positional relationship can change. "Rotational connection" means that the two are connected and can rotate relative to each other after connection. "Sliding connection" means that the two are connected and can slide relative to each other after connection. In addition, when two components are integrated through an integral molding process, it means that during the process of forming one of the two components, this component is connected to the other component together, and there is no need to connect the two components through additional processing (such as bonding, welding, snap connection, screw connection). The relative arrangement of component A and component B can be such that when 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, projection C and projection D can at least mostly overlap. In some embodiments, mostly overlapping can be any of the following situations: Projection C is completely located within projection D. Or, projection D is completely located within projection C. Or, projection C and projection D intersect, and the intersection area of projection C and projection D accounts for a proportion higher than 50% of projection C or projection D.

[0211] In the embodiments of the present application, the orientation terms mentioned, such as "top", "bottom", "inner", "outer", "upper", "lower", etc., are only with reference to the direction of the attached drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0212] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after. "Plurality" means at least two.

It can be understood that Figure 1 and the related drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 1 and the following drawings. In addition, when the electronic device 1000 is a device in some other forms, the electronic device 1000 may not include the screen 300.

[0217] Such as Figure 1 and Figure 2 As shown, in some embodiments, the screen 300 is installed 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 place the components of the electronic device 1000, such as a battery, a receiver, or a microphone, etc. Among them, the screen 300 can be a flat screen or a curved screen.

[0218] Exemplarily, 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 the Figure 1 circular shape shown, and it can also be an oval or an irregular shape. The light outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201. The camera module 100 can collect the light entering the interior of the electronic device 1000.

[0219] Such as 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 in sequence from the image side to the object side. It can be 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 the image information carried by the ambient light into an electrical signal.

[0220] It can be 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. In this way, compared with the camera module 100 in which the first optical element 103, the first optical path conversion element 102, and the image sensor assembly 101 are separately arranged, the camera module 100 in this embodiment has a smaller volume, which is beneficial to realizing the miniaturization setting of the camera module 100, and thus is beneficial to saving the internal space of the electronic device 1000.

[0221] Exemplarily, the first optical element 103 may include a lens group or multiple lens groups. When the first optical element 103 includes multiple lens groups, at least one lens group may move along the optical axis direction. For example, as Figure 2 shown, the first optical element 103 includes a first lens group 1031 and a second lens group 1032. The first lens group 1031 may move along the optical axis direction. The second lens group 1032 may be a lens group with a fixed position.

[0222] As Figure 2 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 that are 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 can be understood that at least part of the light enters the first optical element 103, passes through the first optical element 103, then enters the first optical path conversion element 102 through the first side surface 1021 of the first optical path conversion element 102, and after total reflection on the third side surface 1023 and reflection on the second side surface 1022 of the first optical path conversion element 102, it propagates to the image sensor assembly 101.

[0223] Exemplarily, the second side surface 1022 of the first optical path conversion element 102 may face the screen 300. The image sensor assembly 101 is located on the side where the third side surface 1023 of the first optical path conversion element 102 is located. In this way, on the one hand, the image sensor assembly 101 can effectively utilize the space where the third side surface 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 is not likely to 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 perpendicularly arranged, and the third side surface 1023 of the first optical path conversion element 102 is an inclined surface.

[0225] Figure 3 Is Figure 2 a schematic structural diagram of one embodiment of the image sensor assembly 101 shown.

[0226] Please refer to Figure 3 , and in combination with Figure 2As shown, the image sensor component 101 includes a top surface 10a and a bottom surface 10d arranged back-to-back, and a first side surface 10b and a second side surface 10c arranged back-to-back. The top surface 10a and the bottom surface 10d of the image sensor component 101 are connected between the first side surface 10b and the second side surface 10c of the image sensor component 101. The bottom surface 10d of the image sensor component 101 is oppositely arranged with the third side surface 1023 of the first optical path conversion element 102.

[0227] It can be understood that, in one embodiment, the image sensor component 101 does not include the top surface 10a. At this time, the first side surface 10b and the second side surface 10c of the image sensor component 101 are directly connected and perpendicular to each other. In this way, the volume of the image sensor component 101 is relatively large, which is not conducive to miniaturization. In this embodiment, by forming the top surface 10a on the image sensor component 101, the space on the side where the top surface 10a of the image sensor component 101 is located can be saved. In this way, the volume of the image sensor component 101 is small, which is conducive to miniaturization.

[0228] Exemplarily, the first side surface 10b of the image sensor component 101 is arranged at an acute angle with the bottom surface 10d. It can be understood that, in one embodiment, if the length of the bottom surface 10d of the image sensor component 101 remains unchanged and the first side surface 10b of the image sensor component 101 is perpendicular to the bottom surface 10d of the image sensor component 101, at this time, the first side surface 10b of the image sensor component 101 is likely to increase the height of the camera module 100 (that is, the first side surface 10b of the image sensor component 101 will protrude Figure 2 from the dashed box). In this embodiment, by arranging the first side surface 10b of the image sensor component 101 at an acute angle with the bottom surface 10d, the first side surface 10b of the image sensor component 101 is prevented from increasing the height of the camera module 100 to a large extent.

[0229] Exemplarily, the second side surface 10c of the image sensor component 101 is arranged at an acute angle with the bottom surface 10d. It can be understood that, in one embodiment, if the length of the bottom surface 10d of the image sensor component 101 remains unchanged and the second side surface 10c of the image sensor component 101 is perpendicular to the bottom surface 10d of the image sensor component 101, at this time, the second side surface 10c of the image sensor component 101 is likely to increase the length of the camera module 100 (that is, the second side surface 10c of the image sensor component 101 will protrude Figure 2 from the dashed box). In this embodiment, by arranging the second side surface 10c of the image sensor component 101 at an acute angle with the bottom surface 10d, the second side surface 10c of the image sensor component 101 is prevented from increasing the height of the camera module 100 to a large extent.

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

[0231] Exemplarily, the first side surface 10b of the image sensor assembly 101 is obtusely angled with respect to the top surface 10a. And / or, the second side surface 10c of the image sensor assembly 101 is obtusely angled with respect 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] Exemplarily, the first side surface 10b of the image sensor assembly 101 is parallel to the second side surface 1022 of the first optical path conversion element 102.

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

[0234] Exemplarily, the shape of the image sensor assembly 101 can be similar to a "pyramid".

[0235] As Figure 2 shown, the imaging module 100 further includes a second optical path conversion element 104. The second optical path conversion element 104 is located on the object side of the first optical element 103. The second optical path conversion element 104 can also be used to change the optical axis direction of the imaging module 100.

[0236] Exemplarily, the second optical path conversion element 104 can include a prism. The light incident side of the second optical path conversion element 104 is disposed opposite to the light transmissive portion 201. At this time, the light passing through the light transmissive 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 the light passes through the first optical element 103, it enters the first optical path conversion element 102, and after total reflection by the third side surface 1023 and reflection 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 imaging 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 transmissive portion 201. At this time, the light passing through the light transmissive portion 201 can directly enter the first optical element 103.

[0238] In other embodiments, the second optical path conversion element 104 may further include an anti-shake motor. The anti-shake motor is used to drive the prism of the second optical path conversion element 104 to move to achieve optical anti-shake of the imaging module 100.

[0239] It can be understood that the above only schematically shows an implementation manner in which the image sensor component 101 is applied to the camera module 100. In other implementation manners, the image sensor component 101 can also be applied to camera modules 100 with other structures. Specifically, the present application does not make any limitations.

[0240] Figure 4 Yes Figure 3 It is a partial exploded view of an implementation manner of the image sensor component 101 shown.

[0241] Such as Figure 3 And Figure 4 As shown in [relevant figures], the image sensor component 101 includes an anti-shake motor 10, an image sensor module 20, an upper housing 30, and a lower housing 40. For the convenience of description, the width direction of the image sensor component 101 is defined as the X-axis, the length direction of the image sensor component 101 is defined as the Y-axis, and the thickness direction of the image sensor component 101 is defined as the Z-axis. It can be understood that the coordinate system setting of the image sensor component 101 can be flexibly set according to specific actual needs.

[0242] It can be understood that the anti-shake motor 10 can control the image sensor module 20 to move along a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the camera module 100 collects ambient light, if the electronic device 1000 jitters in the X-Y plane due to external forces, the anti-shake motor 10 can control the movement of the image sensor module 20 in the X-Y plane to offset the jitter stroke generated by the camera module 100 in the X-Y plane, so as to avoid or reduce the position offset of the camera module 100 caused by jitter. The camera module 100 of the present application can control the movement of the image sensor module 20 in the X-Y plane through the anti-shake motor 10 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0243] Figure 5 Yes Figure 4 It is a partial exploded view of an implementation manner of the anti-shake motor 10 shown.

[0244] Such as Figure 5 As shown in [relevant figures], the anti-shake motor 10 includes a fixed carrier 11, a movable carrier 12 (also referred to as a moving carrier), a driving magnetic member 13, a first driving coil 14, and a second driving coil 15.

[0245] Exemplarily, the movable carrier 12 includes a first bracket 121 and a second bracket 122.

[0246] Exemplarily, the driving magnetic member 13 includes a first driving magnetic member 131 and a second driving magnetic member 132.

[0247] Exemplarily, the second driving coil 15 includes a first sub-driving coil 151 and a second sub-driving coil 152.

[0248] It can be understood that the anti-shake motor 10 may further include more structures or fewer structures. For example, when the anti-shake motor 10 includes more structures, the anti-shake motor 10 may further include a first circuit board 16, a second circuit board 17, a movable circuit board 18 (also known as TSA, or flexible circuit board), a rolling member 191, and a magnetic attraction magnetic member 192. Exemplarily, the rolling member 191 may be a single ball, a group of balls formed by multiple balls, a sliding shaft, or a convex structure.

[0249] Figure 6 Yes Figure 5 Schematic diagrams of the structure of the fixed carrier 11 shown at different angles. Figure 7 Yes Figure 5 Schematic diagrams of the structure of the fixed carrier 11 shown at another angle.

[0250] As Figure 6 And Figure 7 As shown, the fixed carrier 11 includes a top plate 112, a first side plate 113 and a second side plate 114 arranged oppositely, and a third side plate 115 and a fourth side plate 116 arranged oppositely. Among them, the top plate 112 is connected between the first side plate 113 and the second side plate 114, and is also connected between the third side plate 115 and the fourth side plate 116. The third side plate 115 and the fourth side plate 116 are connected between the first side plate 113 and the second side plate 114. The top plate 112, the first side plate 113, the second side plate 114, the third side plate 115 and the fourth side plate 116 enclose an inner space of the fixed carrier 11.

[0251] Exemplarily, the top plate 112 and the first side plate 113 are arranged at an obtuse angle. And / or, the top plate 112 and the second side plate 114 are arranged at an obtuse angle.

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

[0253] Exemplarily, the fixed carrier 11 is provided with a first through hole 118 and a second through hole 119 arranged at intervals. The first through hole 118 and the second through hole 119 communicate the inner space of the fixed 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 6Partial exploded view of an embodiment of the fixed carrier 11 shown.

[0255] As Figure 8 shown, the fixed 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 and the insulating part 11b can form an integrally molded structural part by means of insert-molding or the like. In this way, the overall strength of the fixed carrier 11 is relatively good.

[0256] Exemplarily, the insulating part 11b includes a first insulating portion 111b, a second insulating portion 112b and a third insulating portion 113b that are oppositely arranged, and a fourth insulating portion 114b and a fifth insulating portion 115b that are oppositely arranged. Among them, 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] As Figure 8 shown, the metal part 11a includes a first metal part 111a, a second metal part 112a and a third metal part 113a. Exemplarily, the first metal part 111a can be embedded in the first insulating portion 111b. The second metal part 112a can be embedded in the second insulating portion 112b. The third metal part 113a can be embedded in the third insulating portion 113b.

[0258] Please refer to Figure 8 and, in combination with Figure 6 and Figure 7 , the first metal part 111a and the first insulating portion 111b can form the top plate 112 of the fixed carrier 11. The second metal part 112a and the second insulating portion 112b can form the first side plate 113 of the fixed carrier 11. The third metal part 113a and the third insulating portion 113b can form the second side plate 114 of the fixed carrier 11. The fourth insulating portion 114b can form the third side plate 115 of the fixed carrier 11. The fifth insulating portion 115b can form the fourth side plate 116 of the fixed 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 part of the first metal part 111a and the first insulating portion 111b enclose a receiving groove 117.

[0259] As Figure 8 shown, the first metal part 111a includes a main body portion 114a and a plurality of extending portions 115a. The plurality of extending portions 115a are spaced apart and connected to the edge of the main body portion 114a. Exemplarily, the plurality of extending portions 115a can be bent relative to the main body portion 114a.

[0260] As shown Figures 6 to 8 in the figure, at least a part 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 arranged back to back. The first surface 1111 of the magnetic shielding sheet 111 is the surface of the top plate 112 facing the inside of the fixed carrier 11, and the second surface 1112 of the magnetic shielding sheet 111 is the surface of the top plate 112 facing the outside of the fixed carrier 11. In other embodiments, the magnetic shielding sheet 111 may also be embedded in the first insulating portion 111b.

[0261] Exemplarily, a plurality of extending portions 115a of the first metal member 111a may be exposed relative to the first insulating portion 111b.

[0262] It can be understood that the above is only a schematic introduction to the structure of a fixed carrier 11. In other embodiments, the structure of the fixed carrier 11 is not specifically limited.

[0263] Fig. 9 is Figure 4 a partial structure schematic of an embodiment of the anti-shake motor 10 shown Figure 1 .

[0264] Please refer to Fig. 9 , and in combination with Figure 7 shown in the figure, the first driving magnetic member 131 of the driving magnetic member 13 is fixed to the first surface 1111 of the magnetic shielding sheet 111, that is, the first driving magnetic member 131 is located in the inner space of the fixed carrier 11.

[0265] Exemplarily, the first driving magnetic member 131 may include a plurality of magnets, and the plurality of magnets are arranged in the first direction X. There are various implementation structures of the first driving magnetic member 131. For example, the first driving magnetic member 131 may include at least three magnets. Among the adjacent three magnets, the polarization directions of the two magnets on the sides are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet in the middle points from one magnet to the other magnet. It can be understood that Fig. 9 only six magnets are schematically shown. For another example, the first driving magnetic member 131 may be a Halbach magnet array. For another example, the first driving magnetic member 131 may adopt a dual-magnet structure, for example, composed of two magnets, and the polar directions of the two magnets are opposite. It can be understood that when the first driving magnetic member 131 adopts a multi-group Halbach magnet combined array arrangement form, the magnetic induction line distribution can be further compressed, the magnetic thrust can be effectively improved, and the utilization rate of the magnetic induction lines can be improved.

[0266] Exemplarily, the first driving magnetic member 131 may include a magnet, that is, the first driving magnetic member 131 may adopt a single-magnet structure, for example, it may be composed of a single magnet, and the magnet includes two parts with opposite polar directions, and the two parts may be arranged in the first direction X. Among them, the magnet may be made by a bipolar magnetization process. In addition, the two parts with opposite polar directions may form a magnet unit. In a single magnet, multiple magnet units may be included. The multiple magnet units are arranged in the first direction X.

[0267] Fig.10 Is Fig. 9 A schematic structural diagram of the partial anti-shake motor 10 shown in another perspective.

[0268] Please refer to Fig.10 and in combination with Figure 6 as shown, the second driving magnetic member 132 of the driving magnetic member 13 is fixed to the second surface 1112 of the magnetic isolation sheet 111. In one embodiment, the second driving magnetic member 132 is located in the accommodation groove 117 of the fixed carrier 11.

[0269] It can be understood that in this embodiment, by fixing the first driving magnetic member 131 to the first surface 1111 of the magnetic isolation sheet 111 and the second driving magnetic member 132 to the second surface 1112 of the magnetic isolation sheet 111, the driving magnetic member 13 is fixed to the fixed carrier 11. In addition, the first driving magnetic member 131 and the second driving magnetic member 132 may be separately fixed to different positions of the fixed carrier 11, and the magnetic isolation sheet 111 may separate the first driving magnetic member 131 and the second driving magnetic member 132.

[0270] Exemplarily, the second driving magnetic member 132 may include multiple magnets, and the multiple magnets are arranged in the second direction Y. There are various implementation structures of the second driving magnetic member 132. For example, the second driving magnetic member 132 may include at least three magnets. Among two adjacent magnets, the polar directions of the two magnets are opposite. It can be understood that Fig.10 only three magnets are schematically shown. For another example, the second driving magnetic member 132 may adopt a two-magnet structure, for example, it may be composed of two magnets, and the polar directions of the two magnets are opposite. For another example, the second driving magnetic member 132 may be a Halbach magnet array. For another example, the second driving magnetic member 132 may include at least three magnets. Among three adjacent magnets, for the two magnets on the sides, the polarization directions are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet in the middle points from one magnet to the other magnet. It can be understood that when the second driving magnetic member 132 adopts a multi-group Halbach magnet combination array arrangement form, the magnetic induction line distribution can be further compressed, the magnetic thrust can be effectively improved, and the utilization rate of the magnetic induction lines can be improved.

[0271] Exemplarily, the second driving magnetic member 132 may include a magnet, that is, the second driving magnetic member 132 may adopt a single-magnet structure, for example, it may be composed of a single magnet, and the magnet includes two parts with opposite polar directions, and the two parts may be arranged in the second direction Y. Wherein, the magnet may be made by a bipolar magnetization process. In addition, the two parts with opposite polar directions may form a magnet unit. In a single magnet, multiple magnet units may be included. The multiple magnet units are arranged in the second direction Y.

[0273] As Fig.11 As shown, the first bracket 121 includes a bottom plate 1211, a first convex block 1212 and a second convex block 1213. The first convex block 1212 and the second convex block 1213 protrude from the same side of the bottom plate 1211.

[0274] Exemplarily, the bottom plate 1211 is provided with a first avoidance hole 1214. The first avoidance hole 1214 may be located between the first convex block 1212 and the second convex block 1213. The number of the first avoidance holes 1214 may be two. The shape of the first avoidance hole 1214 may be elongated. In other embodiments, the position, size, number and shape of the first avoidance hole 1214 are not specifically limited.

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

[0276] Exemplarily, the first bracket 121 has a plurality of first pin ends 1216. The plurality of first pin ends 1216 can be used for electrical connection with other structural members.

[0277] It can be understood that Fig.11 Only some of the first limiting protrusions 1215 and the first pin ends 1216 are labeled schematically.

[0278] Fig.12 Yes Figure 4 Partial structure schematic of an embodiment of the anti-shake motor 10 shown Figure 2 .

[0279] As Fig.12 As shown, the anti-shake motor 10 includes an anti-shake driving chip 193. The anti-shake driving chip 193 is fixed on the first circuit board 16 and is electrically connected to the first circuit board 16.

Both the first position sensor 194 and the second position sensor 195 are fixed to the first circuit board 16 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 through the first circuit board 16.

[0281] Exemplarily, the first circuit board 16 is provided with second avoidance holes 161. The number of the second avoidance holes 161 may be two.

[0284] Please refer to Fig.13 , and in combination with Fig.11 and Fig.12 shown, the first circuit board 16 is fixed to the movable carrier 12. Exemplarily, the first circuit board 16 is fixed to the bottom plate 1211 of the first bracket 121. At least part of the first circuit board 16 may be located between the first bump 1212 and the second bump 1213.

[0285] Exemplarily, the second avoidance holes 161 provided on the first circuit board 16 are disposed opposite to the first avoidance holes 1214 of the first bracket 121.

[0286] Exemplarily, a 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 the 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.

[0288] As Fig.14As shown, the first driving coil 14 is fixed to the first circuit board 16 and electrically connected to the first circuit board 16. The first driving coil 14 is fixed to the bottom plate 1211 of the first bracket 121 through the first circuit board 16.

[0289] Exemplarily, the input end and the output end of the first driving coil 14 form a current loop through the first circuit board 16 and the anti-shake driving chip 193.

[0290] Exemplarily, a plurality of first limiting protrusions 1215 of the first bracket 121 can cooperate with each other to abut against the first driving coil 14, thereby limiting the first driving coil 14. At this time, the connection between the first driving coil 14 and the first circuit board 16 is more stable. For example, the first limiting protrusion 1215 of the first bracket 121 is located inside the first driving coil 14 and abuts against the first driving coil 14 in the first direction X.

[0291] Fig.15 Yes Figure 4 Partial structural schematic of an embodiment of the anti-shake motor 10 shown Figure 5 .

[0292] As Fig.15 shown, the bottom plate 1211 of the first bracket 121 is provided with a rolling element groove 1217. The rolling element 191 is located in the rolling element groove 1217, that is, the rolling element 191 is arranged on the movable carrier 12. Exemplarily, the number of both the rolling element 191 and the rolling element groove 1217 is three. The three rolling elements 191 are correspondingly arranged in the three rolling element grooves 1217 one by one.

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

[0294] As Fig.15 shown, the bottom plate 1211 of the first bracket 121 is provided with a receiving groove 1218. The receiving groove 1218 and the rolling element groove 1217 are arranged at intervals. The anti-shake motor 10 includes a magnetic attracting member 192. The magnetic attracting member 192 is located in the receiving groove 1218, that is, the movable carrier 12 is provided with the magnetic attracting member 192. Exemplarily, the number of both the magnetic attracting member 192 and the receiving groove 1218 is three. The three magnetic attracting members 192 are correspondingly arranged in the three receiving grooves 1218 one by one.

[0295] Exemplarily, the three magnetic attracting members 192 are correspondingly arranged around the three rolling elements 191 one by one.

[0296] It can be understood that by arranging both the rolling member 191 and the magnetic attraction member 192 on the first bracket 121, that is, both the rolling member 191 and the magnetic attraction member 192 are arranged on the same structural member, when the first bracket 121 moves relatively, the relative positions of the rolling member 191 and the magnetic attraction member 192 are not likely to change significantly.

[0297] Fig.16 Is Figure 5 The schematic structural diagram of the second bracket 122 shown at different angles.

[0298] As Fig.16 Shown, the second bracket 122 includes a top surface 1221 and a bottom surface 1222 which are arranged back to back.

[0299] Exemplarily, a plurality of second limiting protrusions 1223 protrude from the bottom surface 1222 of the second bracket 122. The plurality of second limiting protrusions 1223 can limit other structural members. No specific limitations are made on the positions, sizes, quantities and shapes of the second limiting protrusions 1223.

[0300] Exemplarily, a limiting post 1224 protrudes from the bottom surface 1222 of the second bracket 122. The limiting post 1224 can limit other structural members. No specific limitations are made on the positions, sizes, quantities and shapes of the limiting post 1224.

[0301] Exemplarily, the second bracket 122 is provided with fixing holes 1225. The number of the fixing holes 1225 can be one or multiple. No specific limitations are made on the positions, sizes, quantities and shapes of the fixing holes 1225.

[0302] Fig.17 Is Figure 5 The schematic structural diagram of the second circuit board 17 shown at another angle.

[0303] As Fig.17 Shown, the second circuit board 17 has a plurality of third pin ends 171. The plurality of third pin ends 171 can be used for electrical connection with other structural members.

[0304] Exemplarily, the second circuit board 17 is provided with a plurality of limiting holes 172. No specific limitations are made on the positions, sizes, quantities and shapes of the limiting holes 172.

[0305] As Fig.17 Shown, the anti-shake motor 10 includes a third position sensor 173. The third position sensor 173 is fixed to the second circuit board 17 and is electrically connected to the second circuit board 17.

[0306] Fig.18 Is Figure 4 The partial structural schematic of an implementation manner of the anti-shake motor 10 shown Figure 5 。

[0307] Please refer to Fig.18 , and in combination with Fig.16 and Fig.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 through the second circuit board 17.

[0308] Exemplarily, a 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 in the first direction X, they abut against the second circuit board 17.

[0309] Exemplarily, 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. Exemplarily, the limiting post 1224 of the second bracket 122 can be riveted in the limiting hole 172 of the second circuit board 17.

[0310] Fig.19 is Figure 4 a partial structural schematic of an implementation manner of the anti-shake motor 10 as shown Figure 6 。

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

[0312] Exemplarily, the first sub-drive coil 151 and the second sub-drive coil 152 are both fixedly arranged on the second circuit board 17 at intervals and are both electrically connected to the second circuit board 17.

[0313] Exemplarily, a 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 protrusion 1223 of the second bracket 122 is located inside the second drive coil 15 and abuts against the second drive coil 15 in the first direction X.

[0314] Fig. 20 is Figure 4 a partial structural schematic of an implementation manner of the anti-shake motor 10 as shown Figure 7 。 Fig.21 is Fig. 20 The structural schematic diagram of the partial anti-shake motor 10 shown in another perspective.

[0315] As Fig. 20 and Fig.21 shown, the second bracket 122 is fixedly connected to the first bump 1212 and the second bump 1213, and is disposed opposite and spaced apart from the bottom plate 1211.

[0316] Exemplarily, the second bracket 122 can be fixedly connected to the first bump 1212 and the second bump 1213 by an adhesive method.

[0317] Exemplarily, the first bump 1212, the second bump 1213 and the second bracket 122 all include metal parts. The metal parts of the first bump 1212 and the second bump 1213 are both welded to the metal part of the second bracket 122.

[0318] Exemplarily, the fixing post 1212a of the first bump 1212 is inserted into a fixing hole 1225 of the second bracket 122. The fixing post 1213a of the second bump 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] As Fig. 20 and Fig.21 shown, the first drive coil 14 and the second drive coil 15 are disposed facing each other. In addition, the second drive coil 15 forms a current loop with the anti-shake drive chip 193 through the second circuit board 17 (please refer to Fig.19 ), the conductive member in the first bracket 121, and the first circuit board 16.

[0320] It can be understood that the first drive coil 14 and the second drive coil 15 are disposed facing each other, which can mean that the winding plane of the first drive coil 14 faces the winding plane of the second drive coil 15. For example, the winding planes of the first drive coil 14 and the second drive coil 15 can both be disposed parallel to the X-Y plane.

[0321] Exemplarily, 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] Fig. 22 is Figure 4 The partial structure schematic of an implementation manner of the anti-shake motor 10 shown Figure 8 . Fig.23 is Fig. 22 The partial cross-sectional view of an implementation manner of the anti-shake motor 10 at the B-B line shown.

[0323] As Fig. 22 and Fig.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 through the rolling members 191.

[0324] Exemplarily, the rolling members 191 are in contact with the extension portion 115a of the fixed carrier 11 ( Figure 8 The extension portion 115a of the fixed carrier 11 is schematically shown at different angles). It can be understood that since the extension portion 115a of the fixed carrier 11 is made of a metal material, the frictional force between the rolling members 191 and the fixed carrier 11 is small, which is beneficial to improving the stable movement of the movable carrier 12 relative to the fixed carrier 11.

[0325] Exemplarily, the number of the rolling members 191 is three, and the three rolling members 191 are distributed at different positions to support the fixed carrier 11 at three points so as to realize the stable setting of the anti-shake motor 10.

[0326] Exemplarily, grease is provided between the rolling members 191 and the rolling member grooves 1217. In this way, the frictional force between the rolling members 191 and the fixed carrier 11 can be further reduced, so as to better realize the super-slippery system of the rolling members. In addition, the rolling members 191 are not easily disengaged from the rolling member grooves 1217. In other embodiments, the rolling members 191 can also be integrally formed with the movable carrier 12.

[0327] Exemplarily, the magnetic isolation sheet 111 on the top plate 112 of the fixed carrier 11 is located between the bottom plate 1211 of the first bracket 121 and the second bracket 122, that is, a part of the fixed carrier 11 is located between the bottom plate 1211 of the first bracket 121 and the second bracket 122. The magnetic isolation sheets 111 on the top plate 112 of the fixed carrier 11 are spaced apart and oppositely arranged with the bottom plate 1211 of the first bracket 121 and the second bracket 122.

[0328] Exemplarily, the bottom plate 1211 of the first bracket 121 is located in the inner space of the fixed carrier 11. The first convex block 1212 of the first bracket 121 can pass through the first through hole 118 of the fixed carrier 11 from the inner space of the fixed carrier 11 and extend to the outer space of the fixed carrier 11. In addition, the position relationship between the second convex block 1213 of the first bracket 121 (please refer to Fig.21 ) and the second through hole 119 of the fixed carrier 11 (please refer to Figure 6 ) can refer to the position relationship between the first convex block 1212 of the first bracket 121 and the first through hole 118 of the fixed carrier 11. Specifically, it will not be elaborated here.

[0329] Exemplarily, the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15. Among them, both the first driving coil 14 and the second driving coil 15 face the driving magnetic member 13 to drive the movable carrier 12 to move relative to the fixed carrier 11. Among them, the first surface 1111 of the magnetic isolation sheet 111 faces the first driving coil 14, and the second surface 1112 of the magnetic isolation sheet 111 faces the second driving coil 15.

[0330] Fig.24 is Figure 5 a partial exploded view of an embodiment of the anti-shake motor 10 shown.

[0331] Please refer to Fig.24 and in combination with Fig.23 shown, the first driving coil 14 faces the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. Among them, the first driving coil 14 and the first driving magnetic member 131 can form the first driving mechanism of the anti-shake motor 10.

[0332] It can be understood that the first driving coil 14 is arranged facing the first driving magnetic member 131, which means that the winding plane of the first driving coil 14 faces the first driving magnetic member 131. For example, the winding plane of the first driving coil 14 can be arranged parallel to the X-Y plane. Exemplarily, the first driving magnetic member 131 can have two polar directions opposite to each other ( Fig.24 shown by the dotted line with arrows in), where Fig.24 schematically shows that the first driving magnetic member 131 includes three groups of two polar directions opposite to each other.). The polar direction of the first driving magnetic member 131 and the winding plane of the first driving coil 14 can be arranged perpendicular to each other. Among them, the coils of two sections of one first driving coil 14 can be respectively arranged corresponding to the two polar directions of the first driving magnetic member 131, and the current in the coils of the two sections ( Fig.24 shown by the solid line a with arrows in) flows in opposite directions. The side of the first driving magnetic member 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 member 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 member 131 facing the first driving coil 14 is blocked, Fig.24 only the polarity of the side of the first driving magnetic member 131 facing away from the first driving coil 14 is schematically shown. In addition, the number of the first driving coils 14 is three. The three first driving coils 14 are arranged corresponding to the three groups of two polar directions opposite to each other one by one.

[0333] Please refer to Fig.24 and in combination with Fig.23As shown, the first position sensor 194 can be used to detect the change in the first magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. At this time, the first position sensor 194 or the anti-shake driving chip 193 can confirm the displacement of the movable carrier 12 relative to the fixed carrier 11 in the first direction X according to the change in the first magnetic field.

[0334] Please refer to Fig.24 , and in combination with Fig.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 member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. At this time, the second position sensor 195 or the anti-shake driving chip 193 can confirm the displacement of the movable carrier 12 relative to the fixed carrier 11 in the first direction X according to the change in the second magnetic field.

[0335] It can be understood that in the process of confirming the displacement of the movable carrier 12 relative to the fixed carrier 11 in 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 refer to Fig.24 , and in combination with Fig.23 As shown, the first sub-driving coil 151 of the second driving coil 15 faces the second driving magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 in the second direction Y. Among them, the first sub-driving coil 151 of the second driving coil 15 and the second driving magnetic member 132 can form the second driving mechanism of the anti-shake motor 10.

[0337] It can be understood that the first sub-driving coil 151 is arranged facing the second driving magnetic member 132, which means that the winding plane of the first sub-driving coil 151 faces the second driving magnetic member 132. For example, the winding plane of the first sub-driving coil 151 can be arranged parallel to the X-Y plane. Exemplarily, the second driving magnetic member 132 can have two opposite polar directions ( Fig.24 as shown by the dotted line with arrows in Fig.24flows in the opposite direction to that shown by the solid line b with an arrow therein. One side of the second driving magnetic member 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 member 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 member 132 facing away from the first sub-driving coil 151 is blocked, Fig.24 only the polarity of the side of the second driving magnetic member 132 facing the first sub-driving coil 151 is schematically shown. Additionally, Fig.24 it is schematically shown that the second driving magnetic member 132 includes three polar directions, and two adjacent polar directions are opposite. The number of the first sub-driving coils 151 is one.

[0338] Please refer to Fig.24 , and in combination with Fig.23 shown, the third position sensor 173 can be used to detect the change amount of the third magnetic field of the second driving magnetic member 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 confirm the displacement amount of the movable carrier 12 moving relative to the fixed carrier 11 along the second direction Y according to the change amount of the third magnetic field.

[0339] Exemplarily, the driving force generated by the cooperation of the first sub-driving coil 151 and the second driving magnetic member 132 is less than the driving force generated by the cooperation of the first driving coil 14 and the first driving magnetic member 131. In one embodiment, when the number of turns is the same, the number of the first sub-driving coils 151 is less than the number of the 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 member 132 is less than the volume of the first driving magnetic member 131. And / or, when the size is the same, the number of the second driving magnetic members 132 is less than the number of the first driving magnetic members 131.

[0340] Please refer to Fig.24 , and in combination with Fig.23 shown, the second sub-driving coil 152 of the second driving coil 15 faces the second driving magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. Among them, the second sub-driving coil 152 of the second driving coil 15 and the second driving magnetic member 132 can form a third driving mechanism of the anti-shake motor 10.

[0341] It can be understood that the second sub-driving coil 152 is arranged facing the second driving magnetic member 132, which means that the winding plane of the second sub-driving coil 152 faces the second driving magnetic member 132. For example, the winding plane of the second sub-driving coil 152 can be arranged parallel to the X-Y plane. Exemplarily, the number of the second sub-driving coils 152 is two. 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 be respectively arranged corresponding to the two polar directions of the second driving magnetic member 132, and the currents ( Fig.24 The solid line c with an arrow in it indicates the current of the first second sub-driving coil 152, and the solid line d with an arrow indicates the current of the second second sub-driving coil 152) in the coils of the two sections flow in opposite directions. One side of the second driving magnetic member 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 member 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 polar directions of the second driving magnetic member 132. In addition, the two second sub-driving coils 152 share the second driving magnetic member 132 with one first sub-driving coil 151.

[0342] It can be understood that by arranging the two second sub-driving coils 152 in series, the current directions of the two second sub-driving coils 152 are opposite. Thus, when the two second sub-driving coils 152 are energized, the acting forces received by the two second sub-driving coils 152 are opposite. For example, when the first second sub-driving coil 152 receives an acting force in the positive direction of the Y axis, the second second sub-driving coil 152 receives an acting force in the negative direction of the Y axis. At this time, the torques exerted by the two second sub-driving coils 152 on the movable carrier 12 enable the movable carrier 12 to rotate relative to the fixed carrier 11.

[0343] It can be understood that by arranging the second sub-driving coil 152 of the second driving coil 15 and the second driving magnetic member 132, the rotation compensation in the Z-axis direction is realized. For example, when the movable carrier 12 rotates clockwise relative to the fixed carrier 11, the current direction and magnitude on the second sub-driving coil 152 of the second driving coil 15 can be controlled to obtain a compensation driving force for the movable carrier 12 to rotate counterclockwise relative to the fixed carrier 11, so as to realize the rotation compensation of the movable carrier 12 in the Z-axis direction.

[0344] Please refer to Fig.24 and in combination with Fig.23As shown, the first position sensor 194 can be used to detect the change in the first magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. The second position sensor 195 can be used to detect the change in the second magnetic field of the first driving magnetic member 131 when the movable carrier 12 moves relative to the fixed carrier 11 in the first direction X. The first position sensor 194 and the second position sensor 195 cooperate with each other to detect the rotation angle of the movable carrier 12 relative to the fixed carrier 11.

[0345] In one embodiment, the first position sensor 194 or the second position sensor 195 or the anti-shake driving chip 193 can confirm the rotation angle of the movable carrier 12 relative to the fixed carrier 11 according to the change in the first magnetic field and the change in the second magnetic field.

[0346] Fig.25A Yes Fig. 22 It is a partial cross-sectional view of another embodiment of the anti-shake motor 10 shown.

[0347] As Fig.25A shown, exemplarily, the upper housing 30 is fixed to the fixed carrier 11. The upper housing 30 can cover at least a part of the second bracket 122 and the gap between the second bracket 122 and the fixed carrier 11. The upper housing 30 can make the anti-shake motor 10 more beautiful and have better integrity. In addition, when the second driving magnetic member 132 of the driving magnetic member 13 is exposed through the gap between the second bracket 122 and the fixed carrier 11, the upper housing 30 can also be used to cover the second driving magnetic member 132 and protect the second driving magnetic member 132.

[0348] As Fig.25A shown, the upper housing 30 can also cover the first through hole 118 of the fixed carrier 11 ( Figure 3 and Figure 6 schematically shows the first through hole 118 at different angles) and the second through hole 119 ( Figure 6 schematically shows the second through hole 119 at different angles).

[0349] Please refer to Fig.25A , and in combination with Figure 3 shown, the surface of the upper housing 30 facing away from the second bracket 122 can be used to form the top surface 10a of the image sensor assembly 101. A part of the upper housing 30 and the first side plate 113 of the fixed carrier 11 can jointly form the first side surface 10b of the image sensor assembly 101. A part of the upper housing 30 and the second side plate 114 of the fixed carrier 11 can be used to form the second side surface 10c of the image sensor assembly 101.

[0350] Fig.25B Yes Fig. 22The illustrated embodiment is a partial cross-sectional view of the anti-shake motor 10 at line CC.

[0351] See also Fig.25B , and combined with Figure 8 As shown, the multiple extensions 115a of the first metal member 111a of the fixed carrier 11 form a magnetic attraction member, that is, the multiple extensions 115a of the first metal member 111a of the fixed carrier 11 are made of magnetic attraction material, that is, a material that can generate magnetic attraction with a magnet or other magnetic components, such as ferromagnetic material, etc. In this case, the magnetic attraction member can be a part of the metal part of the fixed carrier 11.

[0352] like Fig.25B As shown, the magnetic attraction member 192 is arranged opposite to the extension portion 115a. A magnetic attraction force can be generated between the magnetic attraction member 192 and the extension portion 115a. The magnetic attraction force can make the movable carrier 12 have a tendency to approach the fixed carrier 11. In this way, the movable carrier 12 can stably attract the fixed carrier 11 in the Z-axis direction, and the stability of the movable carrier 12 is better when the movable carrier 12 moves relative to the fixed carrier 11.

[0353] Exemplarily, when there are multiple magnetic members 192 and multiple extension portions 115 a, the multiple magnetic members 192 are disposed opposite to the multiple extension portions 115 a in a one-to-one correspondence.

[0354] Exemplarily, the extension portion 115a is disposed facing the magnetic member 192, so that the relative area between the magnetic member 192 and the extension portion 115a is larger, which is beneficial to increase the magnitude of the magnetic attraction force between the magnetic member 192 and the extension portion 115a.

[0355] It is understandable that the position of the magnetic attraction component 192 can be reasonably set to better avoid and balance the overall magnetic interference of the anti-shake motor 10, that is, to avoid the magnetic interference between the magnetic attraction component 192 and the driving magnetic component 13 as much as possible.

[0356] It is understandable that the extension portion 115a of the fixed carrier 11 can provide a smooth contact surface for the rolling element 191 and can also serve as a magnetic attraction member for the magnetic element 192. The extension portion 115a of the fixed carrier 11 has a "one object, multiple uses" function.

[0357] It can be understood that by disposing both the rolling member 191 and the magnetic attraction member 192 on the movable carrier 12, when the movable carrier 12 moves relative to the fixed carrier 11, the relative positions of the rolling member 191 and the magnetic attraction member 192 are not likely to change significantly. In particular, when the numbers of the rolling member 191 and the magnetic attraction member 192 are both plural, the relative positions between the contact centers of the plural rolling members 191 and the fixed carrier 11 and the magnetic attraction centers of the plural magnetic attraction members 192 are not likely to change. At this time, when the movable carrier 12 moves relative to the fixed carrier 11, the stability of the movable carrier 12 is relatively good, that is, stable pressing and smooth movement between the movable carrier 12 and the fixed carrier 11 are achieved.

[0358] Fig.26 is Figure 5 A schematic structural view of the movable circuit board 18 shown in another angle. Fig. 27 is Figure 5 A partially exploded schematic view of the movable circuit board 18 in one embodiment.

[0359] As Fig.26 and Fig. 27 shown, 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, electrically connected to the first fixing portion 181, and electrically connected to the outside of the movable circuit board 18 through the elastic portion 182 and the second fixing portion 183.

[0360] Exemplarily, the number of the electrical connection portions 184 is two. The electrical connection portion 184 has a plurality of pin ends 1841.

[0361] Exemplarily, the elastic portion 182 is in a spiral shape, a zigzag shape, or a bent shape. In this way, the length of the elastic portion 182 can be increased, so as to greatly reduce the elastic coefficient of the elastic portion 182.

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

[0363] Exemplarily, the elastic portion 182 surrounds at least half of the edge of the first fixing portion 181, or the elastic portion 182 surrounds the edge of the first fixing portion 181 in multiple turns.

[0364] Exemplarily, the elastic coefficient of the movable circuit board 18 in the length direction is K Y , K Y is in the range of 25 to 35. For example, the elastic coefficient of the movable circuit board 18 in the length direction is K Y can be 30.

[0365] and / or, the elastic coefficient of the movable circuit board 18 in the width direction is K X , K X is in the range of 85 to 100. For example, the elastic coefficient of the movable circuit board 18 in the length direction is K X can be 93.

[0366] Exemplarily, 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 can be a steel plate or other metal plate member. The reinforcing portion 185 is provided with an avoidance area 1851. The electrical connection portion 184 passes through the avoidance area 1851, that is, the reinforcing portion 185 is disposed around the electrical connection portion 184.

[0367] Exemplarily, the reinforcing portion 185 can be fixed to the first fixing portion 181 by an adhesive.

[0368] Fig.28 is Figure 4 a partial structural schematic of an embodiment of the anti-shake motor 10 shown in Figure 9 . Fig.29 is Fig.28 a partial cross-sectional view of an embodiment of the anti-shake motor 10 shown in the D-D line.

[0369] Please refer to Fig.28 and Fig.29 , and in combination with Fig.26 and Fig. 27 shown, the movable carrier 12 is fixed to the first fixing portion 181 of the movable circuit board 18. It can be understood that the movable carrier 12 may have no connection relationship with the elastic portion 182 and the second fixing portion 183 of the movable circuit board 18.

[0370] Exemplarily, the first bracket 121 of the movable carrier 12 is fixed to the first fixing portion 181 through the reinforcing portion 185.

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

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

[0373] In one embodiment, the elastic coefficient of the movable circuit board 18 in the width direction is K X , K X is in the range of 85 to 100. The elastic coefficient of the movable circuit board 18 in the length direction is K Y , K Y is in the range of 25 to 35. At this time, the K Y of the movable circuit board 18 is less than K X .

[0374] It can be understood that since the K Y of the movable circuit board 18 is less than K X , the restriction on the stroke of the movable carrier 12 moving relative to the fixed carrier 11 in the second direction Y is less than the restriction on the stroke of the movable carrier 12 moving relative to the fixed carrier 11 in the first direction X. At this time, in this embodiment, the driving force generated by the first sub-driving coil 151 and the second driving magnetic member 132 can be set to be less than the driving force generated by the first driving coil 14 and the first driving magnetic member 131, so as to better match the K Y of the movable circuit board 18 being less than K X . For example, the number of the first sub-driving coils 151 and the number of the second driving magnetic members 132 can be set to be less, which is beneficial to the miniaturization of the anti-shake motor 10.

[0375] Fig.30 is Figure 4 a partial structural schematic of an embodiment of the anti-shake motor 10 shown Figure 10 .

[0376] Please refer to Fig.30 , and in combination with Fig. 27 shown, a part of the electrical connection portion 184 of the movable circuit board 18 passes through the first avoidance hole 1214 of the first bracket 121 of the movable carrier 12 (please refer to Fig.11 ), and is located in the second avoidance hole 161 of the first circuit board 16 (please refer to Fig.12 ). The pin end 1841 of the electrical connection portion 184 is electrically connected to the second pin end 162 of the first circuit board 16.

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

[0378] Fig.31 Yes Figure 4 It is an exploded schematic diagram of an embodiment of the image sensor module 20 shown. Fig.32 Yes Figure 4 It is a partial structure schematic diagram of an embodiment of the image sensor module 20 shown. Fig.33 Yes Fig.32 It is a structure schematic diagram of a part of the image sensor module 20 shown from another angle.

[0379] As Figure 31 to Figure 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 can be understood that the image sensor 22 is also called a photosensitive chip or a 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 can be understood that the image sensor module 20 can include fewer or more structures. For example, the image sensor module 20 can include fewer structures. The image sensor module 20 may also not include the filter holder 23 and / or the filter 24. For another example, the image sensor module 20 includes more structures. The image sensor module 20 can also include electronic components. The electronic components can be capacitors, inductors, or resistors, etc. The electronic components can be electrically connected to the image sensor 22.

[0380] In some embodiments, the image sensor 22 can be fixed to the module circuit board 21 and electrically connected to the module circuit board 21. At this time, signals can be transmitted between the image sensor 22 and the module circuit board 21. The filter holder 23 is fixedly connected to the module circuit board 21. The filter holder 23 and the image sensor 22 can be located on the same side of the module circuit board 21. The filter holder 23 is provided with a through hole 231. The filter 24 is fixedly connected to the filter holder 23. The filter 24 can be located in the through hole 231. The filter 24 is also disposed opposite to the image sensor 22. The filter 24 can be used to filter infrared light, blue light, etc. in the light before entering the image sensor 22, so as to ensure that the image sensor 22 has better imaging quality.

[0381] Fig.34 Yes Figure 3Partial cross-sectional schematic of an embodiment of the shown image sensor assembly 101 at the E-E line Figure 1 。

[0382] As Fig.34 shown, the image sensor module 20 is fixed to the first fixing portion 181 of the flexible circuit board 18. The image sensor module 20 is located on a side of the first fixing portion 181 of the flexible circuit board 18 away from the reinforcing portion 185. It can be understood that the image sensor module 20 may have no connection relationship with the elastic portion 182 and the second fixing portion 183 of the flexible circuit board 18.

[0383] Exemplarily, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing portion 181 of the flexible circuit board 18.

[0384] As Fig.34 shown, the image sensor module 20 is electrically connected to the first fixing portion 181 of the flexible circuit board 18. Exemplarily, the image sensor 22 may be electrically connected to the first fixing portion 181 of the flexible circuit board 18 through the module circuit board 21, and electrically connected to the outside of the image sensor assembly 101 through the elastic portion 182 and the second fixing portion 183 of the flexible circuit board 18.

[0385] Fig.35 is Figure 3 Partial structural schematic of an embodiment of the shown image sensor assembly 101. Fig.36 is Figure 3 Partial cross-sectional schematic of an embodiment of the shown image sensor assembly 101 at the E-E line Figure 2 。

[0386] As Fig.35 and Fig.36 shown, the image sensor module 20 is located on a side of the first fixing portion 181 of the flexible circuit board 18 away from the moving carrier 12. At this time, the image sensor module 20 is fixed to the moving carrier 12 through the flexible circuit board 18. The image sensor module 20 is located on a side of the moving carrier 12 away from the first drive coil 14.

[0387] It can be understood that when the movable carrier 12 moves along the first direction X, the elastic portion 182 of the movable circuit board 18 deforms along the first direction X. The image sensor module 20 and the first fixing portion 181 of the movable circuit board 18 can move along the first direction X following the movable carrier 12. 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 move along the second direction Y following the movable carrier 12. Therefore, the movable carrier 12 can control the movement of the image sensor module 20 along a plane perpendicular to the third direction Z (i.e., the X-Y plane) through the movable circuit board 18. When the imaging module 100 collects ambient light, if the electronic device 1000 jitters in the X-Y plane due to an external force, the movement of the image sensor module 20 in the X-Y plane can be controlled to offset the jitter stroke generated by the imaging module 100 in the X-Y plane, so as to avoid or reduce the position offset of the imaging module 100 caused by jitter, thereby realizing the optical image stabilization of the imaging module 100 and improving the imaging quality of the imaging module 100.

[0388] In addition, 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 through the elastic portion 1821 of the movable circuit board 18. In this embodiment, by controlling the current direction and magnitude on the second sub-driving coil 152 of the second driving coil 15, a compensation driving force for the movable carrier 12 to rotate counterclockwise relative to the fixed carrier 11 is obtained, so as to realize the rotational compensation of the movable carrier 12 in the Z-axis direction. At this time, the image sensor module 20 also performs rotational compensation in the Z-axis direction to offset the jitter stroke generated by the imaging module 100 rotating in the Z-axis direction, thereby avoiding or reducing the position offset of the imaging module 100 caused by jitter, and further realizing the optical image stabilization of the imaging module 100 and improving the imaging quality of the imaging module 100.

[0389] Fig.37 is Figure 5 A schematic structural view of the first bracket 121 shown at another angle.

[0390] As Fig.38 shown, the first bracket 121 further includes a fixing bump 1219. The fixing bump 1219 protrudes from the bottom plate 1211 and is located on a side of the bottom plate 1211 away from the first bump 1212 (please refer to Fig.11 ). And / or the second bump 1213. Exemplarily, the fixing bump 1219 is a square block. The number of the fixing bumps 1219 is two. In other embodiments, the size, number and shape of the fixing bump 1219 are not specifically limited.

[0391] Exemplarily, two fixed bumps 1219 can be located on both sides of the first avoidance hole 1214.

[0392] Fig.38 Yes Figure 3 Partial cross-sectional schematic view of an embodiment of the illustrated image sensor assembly 101 at the F-F line.

[0393] As Fig.37 And Fig.38 As shown, the fixed 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 fixed bump 1219.

[0394] It can be understood that by protruding the fixed bump 1219 on the bottom plate 1211 of the first bracket 121 and using the fixed bump 1219 to pass through the movable circuit board 18, it is directly fixedly connected to the image sensor module 20. In this way, compared with the scheme in which the image sensor module 20 is fixedly connected to the first bracket 121 through 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 bottom plate 1211 of the image sensor module 20 and the first bracket 121 can be in the same plane to a greater extent. On the other hand, when the movable carrier 12 moves in the X-Y 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 Partial cross-sectional schematic of an embodiment of the illustrated image sensor assembly 101 at the E-E line Figure III .

[0396] As Figure 39 As shown, the fixed carrier 11 is fixed to the second fixing portion 183 of the movable circuit board 18. The fixed carrier 11 may have no connection relationship with the first fixing portion 181 and the elastic portion 182 of the movable circuit board 18. In this way, the connection between the anti-shake motor 10 and the image sensor module 20 is more stable. The integrity of the anti-shake motor 10 and the image sensor module 20 is better.

[0397] Figure 40 Yes Figure 3 Partial cross-sectional schematic of an embodiment of the illustrated image sensor assembly 101 at the E-E line Figure IV .

[0398] As Figure 40As shown, the lower housing 40 is fixedly connected to the fixed carrier 11. The lower housing 40 can be located on the side of the fixed carrier 11 away from the upper housing 30. At this time, the lower housing 40 and the upper housing 30 can be located on both sides of the fixed carrier 11. The lower housing 40 can cover at least part of the first bracket 121 and related devices thereon. It can be understood that the lower housing 40 can make the anti-shake motor 10 more beautiful and have better integrity.

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

[0400] Please refer to Figure 40 as shown, and in combination with 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 specifically introduced the architecture of an image sensor assembly 101 in combination with the relevant drawings.

[0402] As Figure 23 and Figure 24 shown, the present application provides a driving architecture of a magnet coil similar to a "sandwich" type. Specifically, the driving magnetic member 13 is fixed to the fixed carrier 11, the first driving coil 14 and the second driving coil 15 are both fixed to the movable carrier 12, and the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15. It can be understood that, on the one hand, the magnetic induction lines on both sides of the driving magnetic member 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 member 13 is relatively high, which is beneficial to increasing the driving stroke of the anti-shake motor 10. On the other hand, compared with the scheme in which the first driving coil 14 and the second driving coil 15 are tiled in the X-Y plane, the first driving coil 14, the driving magnetic member 13, and the second driving coil 15 of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction, compressing the dimensions in the XY-axis direction, and can greatly improve the space utilization rate in the Z-axis direction, and improve the magnetic induction line utilization rate to achieve thrust improvement, making it possible to apply the anti-shake to a telephoto module with a more compact space and a larger required rated stroke.

[0403] As Figure 23 and Figure 24As shown, the driving magnetic member 13 includes a first driving magnetic member 131 and a second driving magnetic member 132. The first driving coil 14 faces the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. The first sub-driving coil 151 of the second driving magnetic member 132 faces the second driving magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the second direction Y. In this way, the movable carrier 12 can move relative to the fixed carrier 11 in a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the camera module 100 collects ambient light, if the electronic device 1000 jitters in the X-Y plane due to external forces, the movement of the image sensor module 20 in the X-Y plane can be controlled to offset the jitter stroke generated by the camera module 100 in the X-Y plane, so as to avoid or reduce the position offset of the camera module 100 caused by jitter, thereby realizing the 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 member 131 and the second driving magnetic member 132 can be arranged along the Z-axis direction, the number of magnets arranged by the first driving magnetic member 131 and the second driving magnetic member 132 in the X-Y plane will not affect each other, which is conducive to maximizing the number of the first driving magnetic member 131 and the second driving magnetic member 132.

[0405] It can be understood that in the "pyramid" stacked anti-shake motor architecture of the present application, the first sub-driving coil 151 is arranged at the top layer of the pyramid and a set of symmetrically connected reverse coils (second sub-driving coil 152) is added to realize rotation compensation to solve the image rotation problem. The second driving magnetic member 132, the magnetic isolation sheet 111, and the first driving magnetic member 131 are arranged from top to bottom in the middle layer, and the first driving coil 14 and the image sensor module 20 are arranged at the bottom layer of the pyramid. The overall combination realizes the anti-shake function of the three-axis decoupled image sensor 22.

[0406] As Figure 23 and Figure 24 shown, the fixed carrier 11 includes a magnetic isolation sheet 111. The first driving magnetic member 131 is fixed to the first surface 1111 of the magnetic isolation sheet 111, and the second driving magnetic member 132 is fixed to the second surface 1112 of the magnetic isolation sheet 111. In this way, the magnetic isolation sheet 111 can effectively isolate the magnetic induction line crosstalk between the first driving magnetic member 131 and the second driving magnetic member 132, and ensure the utilization rate of the magnetic induction lines of the first driving magnetic member 131 and the second driving magnetic member 132.

[0407] As Figure 2 and Figure 3As shown in the figure, the image sensor component 101 is disposed on the side where the hypotenuse of the first optical path conversion element 102 is located. In this way, on the one hand, the image sensor component 101 can effectively utilize the space on the side of the hypotenuse of the first optical path conversion element 102, improving the space utilization rate; on the other hand, the image sensor component 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 component 101 is not likely to increase the thickness of the electronic device 1000.

[0408] As Figure 2 and Figure 3 shown in the figure, by setting the shape of the image sensor component 101 to be similar to a "pyramid", on the one hand, the volume of the image sensor component 101 can be greatly reduced to achieve miniaturization; on the other hand, when the image sensor component 101 is disposed on the side where the hypotenuse of the first optical path conversion element 102 is located, the larger bottom of the image sensor component 101 can be close to the hypotenuse of the first optical path conversion element 102, and the smaller bottom of the image sensor component 101 can be far from the hypotenuse of the first optical path conversion element 102, so as to make the most of the spare space on the side where the hypotenuse of the first optical path conversion element 102 is located. It can be understood that the image sensor component 101 of the present application can ensure that the volume of the camera module 100 will not be greatly increased while making the most of the spare space on the side where the hypotenuse of the first optical path conversion element 102 is located, thereby improving the overall space utilization rate of the telephoto module, occupying less height and length of the module compared with the traditional bottom plate SOI S, and optimizing the support module space.

[0409] Combined with Figure 26 and Figure 27 shown in the figure, in this embodiment, the driving force generated by the cooperation of the first driving coil 14 and the first driving magnetic member 131 is set to be relatively large to solve the problem that the movement stroke of the movable circuit board 18 is limited due to the relatively large elastic coefficient of the movable circuit board 18 in the first direction X. For example, by setting the first driving magnetic member 131 with a larger number of magnets and the first driving coil 14 with a larger number, a relatively large driving force in the first direction X can be obtained.

[0410] In addition, in this embodiment, the first driving magnetic member 131 with a larger number of magnets and the first driving coil 14 with a larger number are disposed near the bottom of the image sensor component 101 to make the most of the spare space on the side where the hypotenuse of the first optical path conversion element 102 is located.

[0411] Combined with Figure 26 and Figure 27As shown, in this embodiment, the driving force generated by the cooperation of the first sub-driving coil 151 and the second driving magnetic member 132 is set to be small to match the small elastic coefficient of the movable circuit board 18 in the second direction Y, and the movement stroke of the movable circuit board 18 is limited to a small extent. For example, by setting the first driving magnetic member 131 with a smaller number of magnets and the first driving coil 14 with a smaller number, a smaller driving force in the second direction Y can be obtained.

[0412] In addition, in this embodiment, the second driving magnetic member 132 with a smaller number of magnets and the second driving coil 15 with a smaller number are arranged near the top of the image sensor assembly 101 to make the most of the free space on the side where the hypotenuse of the first optical path conversion element 102 is located.

[0413] As Figure 23 and Figure 24 shown, the first sub-driving coil 151 of the second driving coil 15 faces the second driving magnetic member 132 to drive the movable carrier 12 to move relative to the fixed carrier 11 in the second direction Y. The second sub-driving coil 152 of the second driving coil 15 faces the second driving magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. It can be understood that the second sub-driving coil 152 and the first sub-driving coil 151 share the second driving magnetic member 132, which maximally improves the space utilization rate.

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

[0415] First, by setting the elastic part 182 of the movable circuit board 18 in a spiral shape, a zigzag shape or a bent shape, the length of the elastic part 182 is increased, thereby greatly reducing the elastic coefficient of the elastic part 182. In this way, the movement stroke of the movable circuit board 18 is limited to a small extent, which is beneficial to the setting of the movable carrier 12 having a large anti-shake stroke. In addition, the spiral-shaped low-K-value elastic part 182 can effectively compress the dimensions in the X and Y axis directions while maintaining a small size in the Z axis direction, reduce crosstalk in the X-Y plane movement, and optimize the electromagnetic driving performance and power consumption performance.

[0416] In addition, in this embodiment, by setting the second sub-driving coil 152 to face the second driving magnetic member 132 to drive the movable carrier 12 to rotate relative to the fixed carrier 11, rotation compensation can be performed to suppress the rotation (rotation) and crosstalk of the movable circuit board 18.

[0417] Combined with Figure 26 and Figure 27As shown, compared with the traditional main camera anti-shake solution, in the present solution, the module circuit board 21, the movable circuit board 18, the first circuit board 16, and the anti-shake drive chip 193 of the image sensor module 20 are arranged separately in the Z-axis direction. By providing an electrical connection portion 184 on the movable circuit board 18, the electrical connection between the image sensor 22 and the anti-shake drive chip 193 is achieved, effectively utilizing the space in the Z-axis (optical axis direction) and further improving the space utilization rate in the X-Y plane.

[0418] The structure of the image sensor assembly 101 has been specifically introduced above in combination with relevant drawings. Below, the structure of an image sensor assembly 101 will be specifically introduced again in combination with relevant drawings. It can be understood that the same technical content as above will not be specifically described below.

[0419] Figure 41 is Figure 2 The structural schematic diagram of another embodiment of the image sensor assembly 101 shown. Figure 42 is Figure 41 The partial exploded schematic diagram of an embodiment of the image sensor assembly 101 shown.

[0420] As Figure 41 and Figure 42 As shown in FIGS. and, the image sensor assembly 101 includes an anti-shake motor 10, an image sensor module 20, and an upper housing 30.

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

[0422] Exemplarily, the movable carrier 12 includes a first bracket 121 and a second bracket 122.

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

[0424] Exemplarily, 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 number of the first sub-driving coils 141 and the third sub-driving coils 143 of the first driving coil 14 is one each. The number of the second sub-driving coils 142 of the first driving coil 14 is two. In other embodiments, the numbers of the first sub-driving coil 141, the second sub-driving coil 142, and the third sub-driving coil 143 are not specifically limited.

[0426] Exemplarily, the second driving coil 15 includes a first sub-driving coil 151, a second sub-driving coil 152, and a third sub-driving coil 153. In other embodiments, the second driving coil 15 may also not include the second sub-driving coil 152 and / or the third sub-driving coil 153.

[0427] In one embodiment, the number of the first sub-driving coils 151 and the third sub-driving coils 153 of the second driving coil 15 is one each.

[0446] Figure 47 Is Figure 41 Partial structural schematic of an embodiment of the anti-shake motor 10 shown Figure V 。 Figure 48 Is Figure 47 Partial exploded view of an embodiment of the driving magnetic member 13, the first driving coil 14, and the second driving coil 15 shown.

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

[0448] Exemplarily, the first driving magnetic member 131 is located between the first sub-driving coil 141 of the first driving coil 14 and the first sub-driving coil 151 of the second driving coil 15. The first sub-driving coil 141 of the first driving coil 14 and the first sub-driving coil 151 of the second driving coil 15 both face the first driving magnetic member 131 to drive the movable carrier 12 to move relative to the fixed carrier 11 along the first direction X. It can be understood that for the driving manner of the first sub-driving coil 141 of the first driving coil 14 and the first driving magnetic member 131, and the driving manner of the first sub-driving coil 151 of the second driving coil 15 and the first driving magnetic member 131, reference can be made to Figure 24 the driving manner of the first driving coil 14 and the first driving magnetic member 131 as illustrated. Specifically, it will not be elaborated here.

[0449] Exemplarily, the second driving magnetic member 132 is located between the second sub-driving coil 142 of the first driving coil 14 and the second sub-driving coil 152 of the second driving coil 15. The second sub-driving coil 142 of the first driving coil 14 and the second sub-driving coil 152 of the second driving coil 15 both face the second driving magnetic member 132 to drive the movable carrier relative to the fixed carrier 11 to move along the second direction Y. It can be understood that for the driving manner of the second sub-driving coil 142 of the first driving coil 14 and the second driving magnetic member 132, and the driving manner of the second sub-driving coil 152 of the second driving coil 15 and the second driving magnetic member 132, reference can be made to Figure 24 the driving manner of the first sub-driving coil 151 and the second driving magnetic member 132 as illustrated. Specifically, it will not be elaborated here.

[0450] Exemplarily, the third driving magnetic member 133 is located between the third sub-driving coil 143 of the first driving coil 14 and the third sub-driving coil 153 of the second driving coil 15. The third sub-driving coil 143 of the first driving coil 14 and the third sub-driving coil 153 of the second driving coil 15 face the third driving magnetic member 133 to drive the movable carrier 12 to rotate relative to the fixed carrier 11. It can be understood that for the driving manner of the third sub-driving coil 143 of the first driving coil 14 and the third driving magnetic member 133, and the driving manner of the third sub-driving coil 153 of the second driving coil 15 and the third driving magnetic member 133, reference can be made to Figure 24 the driving manner of the second sub-driving coil 152 and the second driving magnetic member 132 as illustrated. Specifically, it will not be elaborated here.

[0451] The above specifically introduced the architecture of an image sensor assembly 101 in conjunction with the relevant drawings.

[0452] As Figure 47 andFigure 48 As shown in the figure, the present application provides a driving architecture of a magnet coil similar to a "sandwich" type. Specifically, the driving magnetic member 13 is fixed to the fixed carrier 11, the first driving coil 14 and the second driving coil 15 are both fixed to the movable carrier 12, and the driving magnetic member 13 is located between the first driving coil 14 and the second driving coil 15. It can be understood that, on the one hand, the magnetic induction lines on both sides of the driving magnetic member 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 member 13 is relatively high, which is beneficial to increasing the driving stroke of the anti-shake 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 X-Y plane, the first driving coil 14, the driving magnetic member 13, and the second driving coil 15 of the present application are arranged in sequence in the Z-axis direction, effectively utilizing the space in the Z-axis direction, compressing the dimensions in the X-Y axis direction, and can greatly improve the space utilization rate in the Z-axis direction, and improve the magnetic induction line utilization rate to achieve thrust improvement, making it possible to apply anti-shake to a telephoto module with a more compact space and a larger required rated stroke.

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

[0454] The structure of the image sensor component 101 has been specifically introduced above in combination with the relevant drawings. The structure of an image sensor component 101 will be specifically introduced below in combination with the relevant drawings. It can be understood that the same technical content as above will not be specifically described below.

[0455] Figure 49 is Figure 2 a partial exploded view of another embodiment of the shown image sensor component 101.

[0456] As Figure 49 shown, the image sensor component 101 includes an anti-shake motor 10, an image sensor module 20, and an upper housing 30. For the setting manners of the image sensor module 20 and the upper housing 30, reference can be made to the setting manners of the image sensor module 20 and the upper housing 30 above. Specifically, it will not be elaborated here.

[0457] As Figure 49As shown, the anti-shake motor 10 includes a fixed carrier 11, a movable carrier 12, a driving magnetic member 13, a first driving coil 14, a second driving coil 15, and a movable circuit board 18. For the fixed carrier 11, the movable carrier 12, the driving magnetic member 13, the first driving coil 14, the second driving coil 15, and the movable circuit board 18, reference can be made to the fixed carrier 11, the movable carrier 12, the driving magnetic member 13, the first driving coil 14, the second driving coil 15, and the movable circuit board 18 in the respective embodiments above. Among them, the difference is that the driving magnetic member 13 includes a first driving magnetic member 131 and a second driving magnetic member 132, that is, the driving magnetic member 13 does not include a third driving magnetic member 133. The first driving coil 14 includes a first sub-driving coil 141 and a second sub-driving coil 142, that is, the first driving coil 14 does not include a third sub-driving coil 143. The second driving coil 15 includes a first sub-driving coil 151 and a second sub-driving coil 152, that is, the second driving coil 15 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 through a guiding bracket 196 to realize the movement of the movable carrier 12 relative to the fixed carrier 11 in the X-Y plane. Specifically as follows:

[0459] As Figure 49 shown, the anti-shake motor 10 further includes a guiding bracket 196. The guiding bracket 196 includes a first supporting portion 1961, a second supporting portion 1962, and a third supporting portion 1963. The first supporting portion 1961, the second supporting portion 1962, and the third supporting portion 1963 are connected to the first bracket 121 of the movable carrier 12 through a plurality of first supporting members 197 and are connected to the fixed carrier 11 through a plurality of second supporting members 198, so that the relative movement direction between the movable carrier 12 and the guiding bracket 196 is different from the relative movement direction between the guiding bracket 196 and the fixed carrier 11. It can be understood that the shape of the guiding bracket 196 is not limited to Figure 49 the rectangular shape shown, for example, the shape of the guiding bracket 196 can also be in an "L" shape.

[0460] Exemplarily, the guiding bracket 196 can be provided with a plurality of first sliding shaft grooves 1964. Among them, the plurality of first sliding shaft grooves 1964 are arranged toward the same side of the guiding bracket 196. The number of the first sliding shaft grooves 1964 can be three, and the three first sliding shaft grooves 1964 are respectively located in the first supporting portion 1961, the second supporting portion 1962, and the third supporting portion 1963. The extending direction of the first sliding shaft groove 1964 can be parallel to the first direction X. The first sliding shaft groove 1964 can be recessed from one side surface of the corresponding supporting portion into the interior of the supporting portion.

[0461] Exemplarily, the guiding bracket 196 may also be provided with a plurality of second sliding shaft grooves 1965, and the plurality of second sliding shaft grooves 1965 are arranged facing away from the plurality of first sliding shaft grooves 1964. The number of the second sliding shaft grooves 1965 may be three, and the three second sliding shaft grooves 1965 are respectively located at the first supporting portion 1961, the second supporting portion 1962, and the third supporting portion 1963, and the extending direction of the second sliding shaft grooves 1965 may be parallel to the second direction Y. Wherein, the second sliding shaft grooves 1965 may be recessed from the other surface of the corresponding supporting portion into the interior of the supporting portion.

[0462] As Figure 49 shown, a plurality of first supporting members 197 are correspondingly arranged in the plurality of first sliding shaft grooves 1964. A plurality of second supporting members 198 are correspondingly arranged in the plurality of second sliding shaft grooves 1965.

[0463] Exemplarily, both the first supporting member 197 and the second supporting member 198 may be sliding shaft structures.

[0464] It can be understood that the movable carrier 12 is movably connected to the fixed carrier 11 through the guiding bracket 196, and the movable carrier 12 is not likely to have a problem of rotating relative to the fixed carrier 11. The movement mode of the movable carrier 12 is more stable.

[0465] It can be understood that several structures of the image sensor assembly 101 are introduced above in combination with the related drawings. Several other structures of the image sensor assembly 101 will be introduced below.

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

[0467] For another example, in each of the above embodiments, the movable carrier 12 and the fixed carrier 11 are in a magnetic attraction and pressing manner. In other embodiments, the movable carrier 12 and the fixed carrier 11 may also be in other pressing and stabilizing manners such as elastic elements.

[0468] For another example, in each of the above embodiments, the movable carrier 12 and the fixed carrier 11 are in a single rolling element super-slippery scheme. In other embodiments, the movable carrier 12 and the fixed carrier 11 may also be in a variety of contact manners such as multi-rolling element super-slippery / DLC bumps / sliding shafts.

[0469] For another example, in each of the above embodiments, the positions of the magnetic attraction magnetic member 192 and the magnetic attraction member may be interchanged.

[0470] The structure of the image sensor component 101 has been specifically introduced above in conjunction with the relevant drawings. Below, the structure of an image sensor component 101 will be specifically introduced again in conjunction with the relevant drawings. It can be understood that Figures 5 to 49 Regarding the related design of the anti-shake motor 10 shown, without conflict, it can also be directly applied to the structural design of the anti-shake motor 50 shown below.

[0471] Figure 50 is Figure 2 A schematic structural diagram of another embodiment of the image sensor component 101 shown. Figure 51 is Figure 50 A partial exploded schematic diagram of an embodiment of the image sensor component 101 shown.

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

[0473] It can be understood that the anti-shake motor 50 can control the image sensor module 20 to move along a plane perpendicular to the third direction Z (i.e., the X-Y plane). When the camera module 100 captures ambient light, if the electronic device 1000 jitters in the X-Y plane due to external forces, the anti-shake motor 50 can control the movement of the image sensor module 20 in the X-Y plane to offset the jitter stroke generated by the camera module 100 in the X-Y plane, so as to avoid or reduce the position offset of the camera module 100 caused by jitter. The camera module 100 of the present application can control the movement of the image sensor module 20 in the X-Y plane through the anti-shake motor 50 to achieve optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

In other embodiments, the drive coil 53 may also not include the third drive coil 533 and / or the fourth drive coil 534.

[0478] Exemplarily, the number of the first drive magnetic members 54 is two. In other embodiments, the number of the first drive magnetic members 54 is not specifically limited.

In other embodiments, the second drive magnetic member 55 may also not include the second sub-drive magnetic member 552.

[0480] It can be understood that the anti-shake motor 50 may further include more structures. For example, when the anti-shake motor 50 includes more structures, the anti-shake motor 50 may further include a circuit board assembly 56, and / or a flexible circuit board 57 (also called TSA, or flexible printed circuit), and / or a connecting member 581, and / or a magnetic attracting magnetic member 582. Exemplarily, the connecting member 581 may be a single ball, or a group of balls formed by a plurality of balls, or a sliding shaft, or a convex structure. Hereinafter, the connecting member 581 being a ball will be taken as an example for description. Exemplarily, the number of the connecting members 581 is three. The number of the magnetic attracting magnetic members 582 is one. In other embodiments, the numbers of the connecting member 581 and the magnetic attracting magnetic member 582 are not specifically limited.

Among them, the top plate 511 is connected between the first side plate 512 and the second side plate 513, and is also connected between the third side plate 514 and the fourth side plate 515. The third side plate 514 and the fourth side plate 515 are connected between the first side plate 512 and the second side plate 513. The top plate 511, the first side plate 512, the second side plate 513, the third side plate 514 and the fourth side plate 515 enclose an inner space of the fixed carrier 51.

[0484] Exemplarily, the top plate 511 and the first side plate 512 are arranged at an obtuse angle. And / or, the top plate 511 and the second side plate 513 are arranged at an obtuse angle.

[0486] It can be understood that the fixed carrier 51 may be an integrally formed structural member formed by a metal part and an insulating part through insert-molding or the like. In this way, the overall strength of the fixed carrier 51 is relatively good.

[0487] As Figure 55As shown, by way of example, the anti-shake motor 50 further includes a magnetic attraction member 59. By way of example, the magnetic attraction member 59 may be a part of the metal member that fixes the carrier 51.

The magnetic attraction member 59 may be made of a magnetic attraction material, that is, a material that can generate a magnetic attraction force with a magnet or other magnetic components, such as ferromagnetic materials, etc.

[0490] By way of example, the mounting portion 5611 may be generally flat. The connecting portion 5612 may be generally bent. The pin end portion 5613 may also be generally flat. By way of example, the plate surface of the pin end portion 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] By way of example, the mounting portion 5611 includes a first surface 5614 and a second surface 5615 arranged along the third direction Z.

[0497] Exemplarily, the number of the third drive coils 533 is multiple. The multiple third drive coils 533 are located on different sides of the second drive coil 532. For example, the number of the second drive coils 532 is one. The number of the third drive coils 533 is two. The two third drive coils 533 can be located on both sides of the second drive coil 532 in the length direction, that is, the second drive coil 532 is located between the two third drive coils 533. It can be understood that the arrangement of the third drive coil 533 and the second drive coil 532 in this embodiment can also be applied to the arrangement of the first sub-drive coil 151 and the second sub-drive coil 152 of the anti-shake motor 10 described above. Details are not elaborated here.

[0498] Exemplarily, the fourth drive coil 534 can be located around the second drive coil 532. In one embodiment, the fourth drive coil 534, the third drive coil 533, and the second drive coil 532 can be arranged along the first direction X. For example, the number of the fourth drive coils 534 is one. The number of the fourth drive coils 534 is one. The fourth drive coil 534 can be located on one side of one 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] Such as Figure 57 andFigure 58 As shown, the drive chip 562 is fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. Exemplarily, the drive 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 drive chip 562 is not specifically limited. For example, if the board space of the second surface 5615 of the mounting portion 5611 permits, the drive chip 562 can also be fixed to the second surface 5615 of the mounting portion 5611.

[0500] It can be understood that the drive coil 53 is electrically connected to the drive chip 562 through the motor circuit board 561. The drive chip 562 can control the current situation of the drive coil 53 (such as whether current is passed or the magnitude of the current when energized, etc.).

[0501] Exemplarily, 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 situation of the first drive coil 531, the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 (such as whether current is passed or the magnitude of the current when energized, etc.).

[0502] Figure 59 is Figure 51 a partial structural schematic diagram of an embodiment of the anti-shake motor 50 shown Figure II . Figure 60 is Figure 59 a structural schematic diagram of a part of the anti-shake motor 50 shown from another angle.

[0503] Please refer to Figure 59 and Figure 60 , and in combination with Figure 57 and Figure 58 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 through 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 one side of the top plate 511 of the fixed carrier 51 away from the inner space of the fixed carrier 51. The pin end portion 5613 of the motor circuit board 561 is fixed to one side of the second side plate 513 of the fixed carrier 51 away from the inner space of the fixed carrier 51. In this way, the motor circuit board 561 extends from the top plate 511 of the fixed carrier 51 to the second side plate 513 of the fixed carrier 51. It can be understood that the second drive coil 532, the third drive coil 533, and the fourth drive coil 534 are located on one side of the top plate 511 of the fixed carrier 51 away from the inner space of the fixed carrier 51. The second drive coil 532, the third drive coil 533, and the fourth drive coil 534 can all be located outside the fixed carrier 51. In addition, the drive chip 562 (please refer to Figure 58 ) can be located between the motor circuit board 561 and the top plate 511 of the fixed carrier 51. The motor circuit board 561 and the top plate 511 of the fixed carrier 51 can also be used to protect the drive chip 562 (please refer to Figure 58 ).

[0505] Please refer to Figure 60 , and in combination with Figure 55 and Figure 58 as shown, at least a part of the first drive coil 531 is located in the mounting hole 5111 of the fixed carrier 51 and is exposed relative to the inner space of the fixed carrier 51. It can be understood that when the number of the first drive coils 531 and the mounting holes 5111 are both multiple, the multiple first drive coils 531 are arranged in the multiple mounting holes 5111 in a one-to-one correspondence. For example, when the number of the first drive coils 531 and the mounting holes 5111 are both three, the three first drive coils 531 are arranged in the three mounting holes 5111 in a one-to-one correspondence. In this way, in the Z-axis direction, the first drive coil 531 and the fixed carrier 51 have an overlapping area, so that the size in the Z-axis direction can be compressed.

[0506] Exemplarily, when the number of the first drive coils 531 is three, two of the first drive coils 531 are located on one side of the magnetic attraction member 59, and the other first drive coil 531 is located on the other side of the magnetic attraction member 59. In this way, it is possible to avoid the installation positions of the three first drive coils 531 from greatly affecting the installation position of the magnetic attraction member 59, so that the magnetic attraction member 59 is arranged as close as possible to the center position of the fixed carrier 51.

[0507] Please refer to Figure 60 , and in combination with Figure 55 and Figure 58As shown, exemplarily, the fixed carrier 51 has a plurality of first limiting blocks 516a, and the plurality of first limiting blocks 516a 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 can be understood that Figure 55 and Figure 60 only one first limiting block 516a is schematically marked out.

[0508] Please refer to Figure 59 , and in combination with 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 driving coil 532, the third driving coil 533, and the fourth driving coil 534 to improve the connection stability between the second driving coil 532, the third driving coil 533, the fourth driving coil 534 and the fixed carrier 51. It can be understood that Figure 53 , Figure 54 and Figure 59 only one second limiting block 516b is schematically marked out.

[0509] Figure 61 is Figure 52 an enlarged schematic view of the first bracket 521 shown in one embodiment.

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

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

[0512] Exemplarily, the bottom plate 5211 is further provided with 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 can be arranged at intervals with the first installation groove 5214. In one embodiment, the number of the first grooves 5215 is multiple. The multiple first grooves 5215 are arranged at intervals. For example, the number of the first grooves 5215 is three. In other embodiments, the number of the first grooves 5215 is not specifically limited.

[0513] Exemplarily, the bottom plate 5211 is further provided with a second installation groove 5216. The opening of the second installation groove 5216 is located in the inner space of the first bracket 521. The second installation groove 5216 may be arranged at intervals with the first installation groove 5214 and the first groove 5215. The second installation groove 5216 may be located between two first installation grooves 5214.

[0514] Exemplarily, the bottom plate 5211 further has a third installation groove 5217. The opening of the third installation groove 5217 is located in the second installation groove 5216.

[0515] Figure 62 Yes Figure 51 Partial structural schematic diagram of an implementation manner of the anti-shake motor 50 shown Figure III .

[0516] As Figure 62 As shown, the first driving magnetic member 54 is fixed to the movable carrier 52. In one implementation manner, the first driving magnetic member 54 is fixed to the bottom plate 5211 of the first bracket 521. The first driving magnetic member 54 may be located in the inner space of the first bracket 521, that is, between the first bump 5212 and the second bump 5213.

[0517] Exemplarily, the first driving magnetic member 54 may be fixed in the first installation groove 5214. When the number of the first driving magnetic members 54 and the first installation grooves 5214 are both multiple, the multiple first driving magnetic members 54 are arranged in the multiple first installation grooves 5214 in a one-to-one correspondence. For example, the number of the first driving magnetic members 54 and the first installation grooves 5214 are both two. The two first driving magnetic members 54 are arranged in the two first installation grooves 5214 in a one-to-one correspondence.

[0518] It can be understood that the first driving magnetic member 54 may include a plurality of magnets, and the plurality of magnets are arranged in the first direction X. There can be various implementation structures of the first driving magnetic member 54. For example, the first driving magnetic member 54 may include at least three magnets. Among three adjacent magnets, the polar directions of two adjacent magnets are opposite. For another example, the first driving magnetic member 54 may adopt a dual-magnet structure, for example, it is composed of two magnets, and the polar directions of the two magnets are opposite. For another example, the first driving magnetic member 54 may include at least three magnets. Among three adjacent magnets, the polarization directions of the two magnets on the sides are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet in the middle points from one magnet to the other magnet. For another example, the first driving magnetic member 54 may be a Halbach magnet array. For another example, the first driving magnetic member 54 may adopt a layout form of a combined array of multiple Halbach magnet groups, so as to further compress the magnetic induction line distribution, effectively improve the magnetic thrust, and improve the utilization rate of magnetic induction lines. The structure of the first driving magnetic member 54 has various setting methods. Specifically, the present application does not make a limitation. Among them, the polar direction may be the direction in which the north pole (N) faces the south pole (S), or the direction in which the south pole (S) faces the north pole (N).

[0519] It can be understood that when the number of the first driving magnetic members 54 is one, the structure of the first driving magnetic member 54 may adopt any one of the structures described above. When the number of the first driving magnetic members 54 is multiple, the first driving magnetic members 54 may adopt the same structure, that is, the first driving magnetic members 54 may adopt any one of the structures described above. When the number of the first driving magnetic members 54 is multiple, the first driving magnetic members 54 may adopt different structures, that is, different first driving magnetic members 54 may adopt any combination of the structures described above.

[0520] In this embodiment, the number of the first driving magnetic members 54 is two. The structure of one of the first driving magnetic members 54 adopts three magnets. Among three adjacent magnets, the polar directions of two adjacent magnets are opposite. The structure of the other first driving magnetic member 54 is composed of two magnets, and the polar directions of the two magnets are opposite.

[0521] As Figure 62 shown, the connecting member 581 is disposed on the movable carrier 52. In one embodiment, the connecting member 581 is disposed in the first groove 5215 of the first bracket 521. When the number of the connecting members 581 and the first grooves 5215 are both multiple, the multiple connecting members 581 are correspondingly disposed in the multiple first grooves 5215 one by one.

[0522] It can be understood that when the connecting member 581 is a ball, the connecting member 581 can be connected to the movable carrier 52, that is, the connecting member 581 can move within the first groove 5215. Exemplarily, grease can be provided between the connecting member 581 and the first groove 5215 to reduce the frictional force between the connecting member 581 and the movable carrier 52. When the connecting member 581 is a sliding shaft or a convex structure, the connecting member 581 can be fixed to the movable carrier 52.

[0523] As Figure 62 shown, the magnetic attracting member 582 is fixed to the movable carrier 52. In one embodiment, the magnetic attracting member 582 is fixed within the third mounting groove 5217 of the first bracket 521. When the number of the magnetic attracting members 582 and the third mounting grooves 5217 are both multiple, the multiple magnetic attracting members 582 are disposed in the multiple third mounting grooves 5217 in a one-to-one correspondence. It can be understood that by disposing both the connecting member 581 and the magnetic attracting member 582 on the first bracket 521, that is, both the connecting member 581 and the magnetic attracting member 582 are disposed on the same structural member, when the first bracket 521 undergoes relative movement, the relative positions of the connecting member 581 and the magnetic attracting member 582 are not likely to change significantly.

[0524] Exemplarily, the magnetic attracting member 582 can be disposed as close as possible to the center of the bottom plate 5211 of the first bracket 521.

[0525] Figure 63 Is Figure 52 a schematic structural diagram of an embodiment of the second bracket 522 shown at different angles.

[0526] As Figure 63 shown, the second bracket 522 is provided with fixing grooves 5221. Exemplarily, the number of the fixing grooves 5221 is two. The two fixing grooves 5221 are spaced apart. In other embodiments, the number, size, and shape of the fixing grooves 5221 are not specifically limited.

[0527] Figure 64 Is Figure 51 a partial structural schematic diagram of an embodiment of the anti-shake motor 50 shown Figure IV .

[0528] Please refer to Figure 64 , and in combination with Figure 63 shown, the second driving magnetic member 55 is fixed to the movable carrier 52. In one embodiment, the second driving magnetic member 55 is fixed within the fixing groove 5221 of the second bracket 522.

[0529] Exemplarily, when the number of the first sub-driving magnetic members 551 of the second driving magnetic member 55 and the number of the fixing grooves 5221 are both two. The two first sub-driving magnetic members 551 are fixedly arranged in the two fixing grooves 5221 in a one-to-one correspondence. When the number of the second sub-driving magnetic members 552 of the second driving magnetic member 55 is one, one second sub-driving magnetic member 552 is fixedly arranged in one of the fixing grooves 5221. The second sub-driving magnetic member 552 can be located at the end of one of the first sub-driving magnetic members 551. It can be understood that the second sub-driving magnetic member 552 can be arranged on the same layer as the first sub-driving magnetic member 551. In other embodiments, the position between the second sub-driving magnetic member 552 and the first sub-driving magnetic member 551 is not specifically limited.

[0530] It can be understood that the first sub-driving magnetic member 551 can include a plurality of magnets, and the plurality of magnets are arranged in the second direction Y. There can be various implementation structures of the first sub-driving magnetic member 551. For example, the first sub-driving magnetic member 551 can adopt a double-magnet structure, such as being composed of two magnets, and the polar directions of the two magnets are opposite. For another example, the first sub-driving magnetic member 551 can include at least three magnets. Among the adjacent three magnets, the polar directions of the adjacent two magnets are opposite. For another example, the first sub-driving magnetic member 551 can include at least three magnets. Among the adjacent three magnets, the polarization directions of the two magnets on the edge are opposite and perpendicular to the arrangement direction of the three magnets, and the polarization direction of the magnet in the middle points from one magnet to the other magnet. For another example, the first sub-driving magnetic member 551 can be a Halbach magnet array. For another example, the first sub-driving magnetic member 551 can adopt a layout form of a combined array of multiple groups of Halbach magnets, so as to further compress the magnetic induction line distribution, effectively improve the magnetic thrust, and improve the utilization rate of magnetic induction lines.

[0531] It can be understood that when the number of the first sub-driving magnetic members 551 is one, the structure of the first sub-driving magnetic member 551 can adopt any one of the structures of the first sub-driving magnetic member 551 described above. When the number of the first sub-driving magnetic members 551 is multiple, the first sub-driving magnetic members 551 can adopt the same structure, that is, the first sub-driving magnetic members 551 can adopt any one of the structures of the first sub-driving magnetic member 551 described above. When the number of the first sub-driving magnetic members 551 is multiple, the first sub-driving magnetic members 551 can adopt different structures, that is, different first sub-driving magnetic members 551 can adopt any combination of the structures of the first sub-driving magnetic member 551 described above.

[0532] In this embodiment, the number of the first sub-driving magnetic members 551 is two. The two first sub-driving magnetic members 551 both adopt a double-magnet structure, such as being composed of two magnets, and the polar directions of the two magnets are opposite.

[0533] It can be understood that the second sub-driving magnetic member 552 may include a plurality of magnets, and the plurality of magnets are arranged in the first direction X. For the specific structure of the second sub-driving magnetic member 552, reference may be made to the specific structure of the first driving magnetic member 54. Specifically, it will not be elaborated here.

[0534] Figure 65 Yes Figure 51 Partial structural schematic of an embodiment of the anti-shake motor 50 shown Figure V .

[0535] Please refer to Figure 65 , and in combination with Figure 62 and Figure 64 shown, the second bracket 522 is fixedly connected to the first bump 5212 and the second bump 5213 of the first bracket 521, and is disposed opposite and spaced apart from the bottom plate 5211 of the first bracket 521. The first bracket 521 and the second bracket 522 form a movable carrier 52. It can be understood that since the movable carrier 52 can be formed by assembling the first bracket 521 and the second bracket 522, when the movable carrier 52 is assembled with other structural members, the first bracket 521, the second bracket 522 and other structural members can be first assembled separately, and then the second bracket 522 is fixed to the first bracket 521. This assembly method can reduce the assembly of other structural members and the movable carrier 52.

[0536] Exemplarily, the second bracket 522 can be fixedly connected to the first bump 5212 and the second bump 5213 by an adhesive method.

[0537] Exemplarily, the first bump 5212, the second bump 5213 and the second bracket 522 all include metal parts. The metal parts of the first bump 5212 and the second bump 5213 are welded to the metal part of the second bracket 522.

[0538] Exemplarily, the second bracket 522 and the first bump 5212, the second bump 5213 can also be matched by positioning posts to improve the connection stability between the second bracket 522 and the first bracket 521.

[0539] Please refer to Figure 65 , and in combination with Figure 62 and Figure 64 shown, the first driving magnetic member 54 and the second driving magnetic member 55 can be spaced apart and disposed opposite to each other.

[0540] Figure 66 Yes Figure 51 Partial structural schematic of an embodiment of the anti-shake motor 50 shown Figure VI . Figure 67 Yes Figure 66 Partial cross-sectional view of an embodiment of the anti-shake motor 50 at the G-G line shown.

[0541] Please refer to Figure 66 and Figure 67 and in combination with 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 through the connecting member 581.

[0542] Exemplarily, when the connecting member 581 is a ball. The connecting member 581 can be arranged in contact with the metal part of the fixed carrier 51. In this way, the frictional force between the connecting member 581 and the fixed carrier 51 is small, which is beneficial to improving the stable movement of the movable carrier 52 relative to the fixed carrier 51.

[0543] Exemplarily, there is grease between the connecting member 581 and the first groove 5215. In this way, the frictional force between the connecting member 581 and the fixed carrier 51 can be further reduced, so as to better realize the ball superlubrication system. In addition, the connecting member 581 is not easily disengaged from the first groove 5215.

[0544] Exemplarily, a part of the top plate 511 of the fixed carrier 51 is located between the bottom plate 5211 of the first bracket 521 and the second bracket 522. A part of the top plate 511 of the fixed carrier 51 and the bottom plate 5211 of the first bracket 521 can be relatively and spaced apart. A part of the top plate 511 of the fixed carrier 51 and the second bracket 522 can be relatively and spaced apart.

[0545] Exemplarily, the bottom plate 5211 of the first bracket 521 is located in the inner space of the fixed carrier 51. The first convex block 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 positional relationship between the second convex block 5213 (please refer to Figure 62 ) of the first bracket 521 and the fixed carrier 51 can refer to the positional relationship between the first convex block 5212 of the first bracket 521 and the fixed carrier 51. Specifically, it will not be elaborated here.

[0546] As Figure 66 and Figure 67 shown, the magnetic attracting magnetic member 582 and the magnetic attracting member 59 are arranged opposite to each other. A magnetic attracting force can be generated between the magnetic attracting magnetic member 582 and the magnetic attracting member 59. The magnetic attracting force can make the movable carrier 52 tend to approach the fixed carrier 51, so that the fixed carrier 51, the connecting member 581 and the movable carrier 52 remain in contact. In this way, the movable carrier 52 can stably attract the fixed carrier 51 in the Z-axis direction, and the stability of the movable carrier 52 is better when the movable carrier 52 moves relative to the fixed carrier 51.

[0547] It can be understood that by reasonably setting the position of the magnetic attraction magnetic member 582, the overall magnetic interference of the anti-shake motor 50 can be better avoided and balanced, that is, the magnetic interference between the magnetic attraction magnetic member 582 and the first driving magnetic member 54 (please refer to Figure 65 ) and the second driving magnetic member 55 (please refer to Figure 64 ) can be minimized.

[0548] It can be understood that by arranging both the connecting member 581 and the magnetic attraction magnetic member 582 on the movable carrier 52, when the movable carrier 52 moves relative to the fixed carrier 51, the relative positions of the connecting member 581 and the magnetic attraction magnetic member 582 are not likely to change significantly. In particular, when the numbers of the connecting member 581 and the magnetic attraction magnetic member 582 are both multiple, the relative positions between the contact centers of the multiple connecting members 581 with the fixed carrier 51 and the magnetic attraction centers of the multiple magnetic attraction magnetic members 582 are not likely to change. At this time, when the movable carrier 52 moves relative to the fixed carrier 51, the stability of the movable carrier 52 is better, that is, stable pressing and smooth movement between the movable carrier 52 and the fixed carrier 51 are achieved.

[0549] Exemplarily, the multiple connecting members 581 are arranged around the magnetic attraction magnetic member 192.

[0550] Figure 68 is Figure 66 a partial cross-sectional view of an embodiment of the anti-shake motor 50 at the H-H line as shown. Figure 69 is Figure 51 a partial exploded view of an embodiment of the anti-shake motor 50 as shown.

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

[0552] As Figure 68 and Figure 69 shown, the first drive coil 531 faces the first driving magnetic member 54 to drive the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X. Exemplarily, the number of the first driving magnetic members 54 is two. The number of the first drive coils 531 is three. Among them, two first drive coils 531 jointly face the same first driving magnetic member 54.

[0553] It can be understood that the first driving coil 531 is arranged facing the first driving magnetic member 54, which means that the winding plane of the first driving coil 531 faces the first driving magnetic member 54. For example, the winding plane of the first driving coil 531 can be arranged parallel to the X-Y plane. Exemplarily, the first driving magnetic member 54 can have at least two polar directions opposite to each other ( Figure 69 as shown by the dashed line with arrows therein, where Figure 69 schematically shows that a first driving magnetic member 54 includes three polar directions, with adjacent two polar directions being opposite to each other. Another first driving magnetic member 54 includes two opposite polar directions). The polar direction of the first driving magnetic member 54 and the winding plane of the first driving coil 531 can be arranged perpendicular to each other. Among them, the coils in two regions of each first driving coil 531 can be respectively arranged corresponding to the two polar directions of the first driving magnetic member 54, and the current flowing directions in the coils of the two regions are opposite. One side of the first driving magnetic member 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 member 54 facing away from the first driving coil 531 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 member 54 facing away from the first driving coil 531 is blocked, Figure 69 only the polarity of the side of the first driving magnetic member 54 facing the first driving coil 531 is schematically shown.

[0554] It can be understood that since at least part of the first driving coil 531 is located in the mounting hole 5111 of the fixed carrier 51, the fixed carrier 51 no longer separates the first driving coil 531 and the first driving magnetic member 54, so that the first driving coil 531 is arranged as close as possible to the first driving magnetic member 54.

[0555] Exemplarily, the anti-shake motor 50 can also include a first position sensor (not shown in the figure). The first position sensor (not shown in the figure) can be fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. The first position sensor (not shown in the figure) is used to detect the displacement change of the movable carrier 52 relative to the fixed carrier 51 moving along the first direction X.

[0556] Figure 70 is Figure 66 a partial cross-sectional view of an implementation manner of the anti-shake motor 50 shown in the I-I line.

[0557] Please refer to Figure 70 and in combination with Figure 68 and Figure 69As shown, the second drive coil 532 faces the first sub-drive magnetic member 551 to drive the movable carrier 52 to move relative to the fixed carrier 51 in the second direction Y. Exemplarily, the number of the second drive coils 532 is one. The number of the first sub-drive magnetic members 551 is two. Among them, one second drive coil 532 faces two first sub-drive magnetic members 551 at the same time.

[0558] It can be understood that the second drive coil 532 is arranged facing the first sub-drive magnetic member 551, which means that the winding plane of the second drive coil 532 faces the first sub-drive magnetic member 551. For example, the winding plane of the second drive coil 532 can be arranged parallel to the X-Y plane. Exemplarily, each first sub-drive magnetic member 551 can include at least two polar directions with opposite directions ( Figure 69 as shown by the dotted line with arrows in the figure), and the polar direction of the first sub-drive magnetic member 551 can be arranged perpendicular to the winding plane of the second drive coil 532. Among them, the coils in two regions of the second drive coil 532 can be respectively arranged corresponding to the two polar directions of the first sub-drive magnetic member 551, and the current flowing directions in the coils of the two regions are opposite. Exemplarily, the middle magnet of one of the first sub-drive magnetic members 551 corresponds to the coils in one region of two second drive coils 532 at the same time. In addition, one side of the first sub-drive magnetic member 551 facing the second drive coil 532 includes a north pole (N) and a south pole (S), and the side of the first sub-drive magnetic member 551 facing away from the second drive coil 532 correspondingly includes a south pole (S) and a north pole (N). It can be understood that since the polarity of the side of the first sub-drive magnetic member 551 facing the second drive coil 532 is blocked, Figure 69 only the polarity of the side of the first sub-drive magnetic member 551 facing the second drive coil 532 is schematically shown.

[0559] Exemplarily, the anti-shake motor 50 can also include a second position sensor (not shown in the figure). The second position sensor (not shown in the figure) can be fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. The second position sensor (not shown in the figure) is used to detect the displacement change of the movable carrier 52 moving relative to the fixed carrier 51 in the second direction Y.

[0560] As Figure 68 and Figure 69 shown, the third drive coil 533 faces the first sub-drive magnetic member 551 of the second drive magnetic member 55 to drive the movable carrier 52 to rotate relative to the fixed carrier 51. Exemplarily, the number of the third drive coils 533 is two. The two third drive coils 533 are arranged to face the two first sub-drive magnetic members 551 one by one. Among them, the arrangement manner of the third drive coil 533 and the first sub-drive magnetic member 551 can refer to the arrangement manner of the second drive coil 532 and the first sub-drive magnetic member 551. Details are not described here again.

[0561] It can be understood that by setting two third driving coils 533 in series, the current directions of the two third driving coils 533 are opposite. Thus, when the two third driving coils 533 are energized, the acting forces received by the two third driving coils 533 are opposite. For example, when the first third driving coil 533 receives an acting force in the positive direction of the Y axis, the second third driving coil 533 receives an acting force in the negative direction of the Y axis. At this time, the torques exerted by the two third driving coils 533 on the movable carrier 52 cause the movable carrier 52 to rotate relative to the fixed carrier 51.

[0562] It can be understood that by setting the third driving coil 533 and the first sub-driving magnetic member 551, rotation compensation in the Z-axis direction can be achieved. For example, when the movable carrier 52 rotates clockwise relative to the fixed carrier 51, the current direction and magnitude on the second sub-driving coil of the second driving coil 532 can be controlled to obtain a compensation driving force for the movable carrier 52 to rotate counterclockwise relative to the fixed carrier 51, thereby achieving rotation compensation of the movable carrier 52 in the Z-axis direction. Additionally, since the third driving coil 533 can share the same first sub-driving magnetic member 551 with the second driving coil 532, the structure of the anti-shake motor 50 is simplified, which is beneficial to the miniaturization of the anti-shake motor 50.

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

[0564] It can be understood that the angular change of the rotation 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 the third position sensor and the fourth position sensor can be fixed to the motor circuit board 561 and electrically connected to the motor circuit board 561. The third position sensor can be used to detect the first displacement change amount of the movable carrier 52 moving relative to the fixed carrier 51 in the first direction X. The fourth position sensor can be used to detect the second displacement change amount of the movable carrier 52 moving relative to the fixed carrier 51 in the first direction X. Through the cooperation of the third position sensor and the fourth position sensor, it is used to detect the angular change of the rotation of the movable carrier 12 relative to the fixed carrier 11. For another example, by setting a third position sensor and using the cooperation between the third position sensor and the first position sensor, it is used to detect the angular change of the rotation of the movable carrier 12 relative to the fixed carrier 11. For another example, by setting a third position sensor and using the cooperation between the third position sensor and the second position sensor, it is used to detect the angular change of the rotation of the movable carrier 12 relative to the fixed carrier 11.

[0565] As Figure 68 and Figure 69 shown, the fourth driving coil 534 faces the second sub-driving magnetic member 552 to drive the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X. Exemplarily, the number of the fourth driving coils 534 is one. The number of the second sub-driving magnetic members 552 is one. Wherein, the arrangement of the fourth driving coil 534 and the second sub-driving magnetic member 552 can refer to the arrangement of the first driving coil 531 and the first driving magnetic member 54. Specifically, it will not be elaborated here.

[0566] It can be understood that while meeting the driving force requirement for the movable carrier 52 to move in the second direction Y and allowing for the space between the second bracket 522 and the fixed carrier 51, the fourth driving coil 534 can be additionally provided in the layer where the second driving coil 532 is located, and the second sub-driving magnetic member 552 can be additionally provided in the layer where the first sub-driving magnetic member 551 is located, and the fourth driving coil 534 and the second sub-driving magnetic member 552 can be used to drive the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X. At this time, the fourth driving coil 534 and the second sub-driving magnetic member 552 can cooperate with the first driving coil 531 and the first driving magnetic member 54, thereby greatly increasing the driving force for the movable carrier 52 to move relative to the fixed carrier 51 in the first direction X, which is beneficial to increasing the stroke of the movable carrier 52 relative to the fixed carrier 51 in the first direction X.

[0567] Figure 71 is Figure 52 an enlarged schematic view of an embodiment of the movable circuit board 57 shown.

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

[0569] Exemplarily, the elastic portion 572 is in a spiral shape, a zigzag shape, or a bent shape. In this way, the length of the elastic portion 572 can be increased, thereby greatly reducing the elastic coefficient of the elastic portion 572.

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

[0571] Exemplarily, the elastic portion 572 surrounds at least half of the edge of the first fixing portion 571, or the elastic portion 572 surrounds the edge of the first fixing portion 571 in multiple turns.

[0572] Exemplarily, the elastic coefficient of the movable circuit board 57 in the length direction is KY , K Y is in the range of 20 to 40. For example, the elastic coefficient of the movable circuit board 57 in the length direction is K Y can be 30.

[0573] And / or, the elastic coefficient of the movable circuit board 57 in the width direction is K X , K X is in the range of 70 to 110. For example, the elastic coefficient of the movable circuit board 57 in the length direction is K X can be 93.

[0574] Exemplarily, the movable circuit board 57 further includes a reinforcing portion 574. The reinforcing portion 574 is fixed to the first fixing portion 571. The reinforcing portion 574 can be a steel plate or other metal plate members. In one embodiment, the reinforcing portion 574 can be fixed to the first fixing portion 571 by an adhesive. In other embodiments, the movable circuit board 57 may not include the reinforcing portion 574.

[0575] Figure 72 is Figure 51 a partial structural schematic of one embodiment of the anti-shake motor 50 shown Figure VII .

[0576] Please refer to Figure 72 , and in combination with Figure 71 shown, the movable carrier 52 is fixed to the first fixing portion 571 of the movable circuit board 57. In one embodiment, the movable carrier 52 may have no connection relationship with the elastic portion 572 and the second fixing portion 573 of the movable circuit board 57.

[0577] Exemplarily, the bottom plate 5211 of the first bracket 521 of the movable carrier 52 is fixed to the reinforcing portion 574, that is, the movable carrier 52 is fixed to the first fixing portion 571 through the reinforcing portion 574.

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

[0579] It can be understood that 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 and 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 and move along the second direction Y.

[0580] Please refer toFigure 72 , and in combination with Figure 69 and Figure 71 As shown, in one embodiment, the elastic coefficient of the movable circuit board 5718 in the width direction is K X , which is less than the elastic coefficient of the movable circuit board 5718 in the length direction, which is K Y , that is, the K of the movable circuit board 5718 Y is less than K X . It can be understood that since the K of the movable circuit board 57 Y is less than K X , the limit on the stroke of the movable carrier 52 moving relative to the fixed carrier 51 in the second direction Y is less than the limit on the stroke of the movable carrier 52 moving relative to the fixed carrier 51 in the first direction X. At this time, in this embodiment, the driving force generated by the second driving coil 532 and the first sub-driving magnetic member 551 can be set to be less than the driving force generated by the first driving coil 531 and the first driving magnetic member 54, so as to better match the K of the movable circuit board 57 Y is less than K X . For example, the number of the second driving coil 532 and the first sub-driving magnetic member 551 can be set to be small, which is beneficial to the miniaturization of the anti-shake motor 50.

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

[0582] As Figures 73 to 74 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 the structures of the various parts of the image sensor module 20, reference can be made to the structures of the various parts of the image sensor module 20 in the above embodiments (for example Figures 31 to 33 ). Specifically, it will not be elaborated here.

[0583] As Figures 73 to 74 shown, the image sensor module 20 is fixed to the first fixing portion 571 of the movable circuit board 57. The image sensor module 20 is located on the side of the first fixing portion 571 of the movable circuit board 57 away from the reinforcing portion 574. It can be understood that the image sensor module 20 may have no connection relationship with the elastic portion 572 and the second fixing portion 573 of the movable circuit board 57.

[0584] Exemplarily, the module circuit board 21 of the image sensor module 20 is fixed to the first fixing portion 571 of the movable circuit board 57. The module circuit board 21 is electrically connected to the movable circuit board 57. In this way, the 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] Exemplarily, the module circuit board 21 is electrically connected to the first fixing portion 571 of the movable circuit board 57 through a soldering process, and then is electrically connected to the second fixing portion 573 through the elastic portion 572 of the movable circuit board 57.

[0586] As Figures 73 to 74 shown, exemplarily, the image sensor module 20 is located on the side of the first fixing portion 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 portion 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 through the movable circuit board 57. Exemplarily, the image sensor module 20 is fixed to the bottom plate 5211 of the first bracket 521 of the movable carrier 52 through the first fixing portion 571 of the movable circuit board 57.

[0587] It can be understood that when the movable carrier 52 moves relative to the fixed carrier 51 in the first direction X, the elastic portion 572 of the movable circuit board 57 deforms in the first direction X. The image sensor module 20 and the first fixing portion 571 of the movable circuit board 57 can move along the first direction X following the movable carrier 52. When the movable carrier 52 moves relative to the fixed carrier 51 in the second direction Y, the elastic portion 572 of the movable circuit board 57 deforms in the second direction Y. The image sensor module 20 and the first fixing portion 571 of the movable circuit board 57 can move along the second direction Y following the movable carrier 52. Therefore, the movable carrier 52 can control the movement of the image sensor module 20 along the plane perpendicular to the third direction Z (i.e., the X-Y plane) through the movable circuit board 57. When the camera module 100 collects ambient light, if the electronic device 1000 jitters in the X-Y plane due to external forces, the movement of the image sensor module 20 in the X-Y plane can be controlled to offset the jitter stroke generated by the camera module 100 in the X-Y plane, so as to avoid or reduce the position offset of the camera module 100 caused by jitter, thereby realizing the optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0588] In addition, when the driving movable carrier 52 rotates clockwise relative to the fixed carrier 51, the movable carrier 52 drives the image sensor module 20 to rotate clockwise through the elastic part 572 of the movable circuit board 57. In this embodiment, by controlling the current direction and magnitude on the third driving coil 533 of the driving coil 53, a compensation driving force for the movable carrier 52 to rotate counterclockwise relative to the fixed carrier 51 is obtained, so as to realize the rotation compensation of the movable carrier 52 in the Z-axis direction. At this time, the image sensor module 20 also performs rotation compensation in the Z-axis direction to offset the jitter stroke generated by the camera module 100 rotating in the Z-axis direction, thereby avoiding or reducing the position offset of the camera module 100 caused by jitter, and further realizing the optical image stabilization of the camera module 100 and improving the imaging quality of the camera module 100.

[0589] As Figure 74 shown, the first bracket 521 further includes a fixing bump 5219. The fixing bump 5219 protrudes from the bottom plate 5211 and is located on the side of the bottom plate 5211 facing the image sensor module 20. Among them, the fixing bump 5219 can pass through the movable circuit board 57 and be fixedly connected to the image sensor module 20. For example, the fixing bump 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 can be understood that by providing a fixing bump 5219 protruding from the bottom plate 5211 of the first bracket 521 and using the fixing bump 5219 to pass through the movable circuit board 57 and be directly fixedly connected to the image sensor module 20. In this way, compared with the solution in which the image sensor module 20 is fixedly connected to the first bracket 521 through 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 bottom plate 5211 of the image sensor module 20 and the first bracket 521 can be in the same plane to a greater extent. On the other hand, when the movable carrier 52 moves in the X-Y 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] As Figure 74 shown, the fixed carrier 51 is fixed to the second fixing part 573 of the movable circuit board 57. The fixed carrier 51 may have no connection relationship with the first fixing part 571 and the elastic part 572 of the movable circuit board 57. In this way, the integrity of the anti-shake motor 10 and the movable circuit board 57 is better.

[0592] As Figure 74 shown, the motor circuit board 561 is electrically connected to the movable circuit board 57. In this way, the driving chip 562 (please refer toFigure 58 ) can be electrically connected to the movable circuit board 57 through the motor circuit board 561 and electrically connected to the outside of the image sensor assembly 101 through the movable circuit board 57.

[0593] Exemplarily, the pin end 5613 of the motor circuit board 561 is electrically connected to the second fixing portion 573 of the movable circuit board 57. In this way, the driving chip 562 (please refer to Figure 58 ) can be electrically connected to the second fixing portion 573 of the movable circuit board 57 through the mounting portion 5611, the connecting portion 5612 and the pin end 5613 of the motor circuit board 561, and electrically connected to the outside of the image sensor assembly 101 through the second fixing portion 573 of the movable circuit board 57. In other words, the driving coil 53 can be electrically connected to the second fixing portion 573 of the movable circuit board 57 through the driving chip 562 and the motor circuit board 561. It can be understood that for the solution in which the driving chip 562 (please refer to Figure 58 ) of the present embodiment is electrically connected to the outside of the image sensor assembly 101, the motor circuit board 561 does not need to be electrically connected to the first fixing portion 571 and the elastic portion 572 of the movable circuit board 57 anymore. In the present embodiment, the driving chip 562 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57, and the solution in which the driving chip 562 is electrically connected to the outside of the image sensor assembly 101 is relatively simple and easier to mass-produce. In other embodiments, the electrical connection manner and the electrical connection position between the motor circuit board 561 and the movable circuit board 57 are not specifically limited.

[0594] In other embodiments, the driving chip 562 can be directly disposed on the second fixing portion 573 of the movable circuit board 57. The driving coil 53 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 through the motor circuit board 561 and electrically connected to the driving chip 562 through the second fixing portion 573 of the movable circuit board 57. In other embodiments, if the anti-shake motor 50 does not include the driving chip 562, the driving coil 53 can be directly electrically connected to the second fixing portion 573 of the movable circuit board 57 through the motor circuit board 561 and electrically connected to the outside of the anti-shake motor 50 through the second fixing portion 573 of the movable circuit board 57.

[0595] Figure 75 Yes Figure 50 is a partial cross-sectional view of an embodiment of the image sensor assembly 101 shown at the K-K line.

[0596] As Figure 75As shown, the upper housing 30 and the lower housing 40 are respectively fixed to both sides of the fixed carrier 51. The upper housing 30, the lower housing 40 and the fixed carrier 51 are assembled and cooperated to jointly cover the internal structure of the movable carrier 52 and the anti-shake motor 50 (for example, the driving coil 53, the first driving magnetic member 54, the second driving magnetic member 55, etc.). The upper housing 30, the lower housing 40 and the fixed carrier 51 are cooperated to jointly package and protect the internal structure of the anti-shake motor 50. It can be understood that through the mutual cooperation of the upper housing 30, the lower housing 40 and the fixed carrier 51, the anti-shake motor 50 can be made more beautiful and have better integrity.

[0597] Exemplarily, the lower housing 40 is further provided with a light-transmitting hole 40a. The lower housing 40 can also be fixed to the second fixing portion 573 of the movable circuit board 57. In this way, on the one hand, the stability of the lower housing 40 can be improved to make the integrity of the image sensor assembly 101 better. On the other hand, the lower housing 40 can also be used to cover the first fixing portion 571, the elastic portion 572 of the movable circuit board 57 and the image sensor module 20. 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, when the external light of the image sensor assembly 101 can pass through the light-transmitting hole 40a of the lower housing 40 and is transmitted to the image sensor 22 through the filter 24.

[0598] Exemplarily, the light-transmitting hole 40a of the lower housing 40 can be directly opposite to the third side surface 1023 of the first optical path conversion element 102 (please refer to Figure 2 ). Figure 2 )

[0599] The above specifically introduces the architecture of another image sensor assembly 101 in combination with the relevant drawings.

[0600] As Figures 68 to 70 shown, the present embodiment provides a driving architecture of a magnet coil similar to a "sandwich" type. Specifically, the driving coil 53 is fixed to the fixed carrier 51, the first driving magnetic member 54 and the second driving magnetic member 55 are both fixed to the movable carrier 52, and the driving coil 53 is located between the first driving magnetic member 54 and the second driving magnetic member 55. It can be understood that compared with the scheme in which the first driving magnetic member 54 and the second driving magnetic member 55 are tiled in the X-Y plane, the first driving magnetic member 54, the driving coil 53 and the second driving magnetic member 55 of the present application are sequentially arranged 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 can be understood that the first driving coil 531 faces the first driving magnetic member 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 member 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 X-Y plane). When the camera module 100 collects ambient light, if the electronic device 1000 jitters in the X-Y plane due to an external force, the movement of the image sensor module in the X-Y plane can be controlled to cancel the jitter stroke generated by the camera module 100 in the X-Y plane, so as to avoid or reduce the position offset of the camera module 100 caused by jitter, thereby realizing the 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 member 54 and the second driving magnetic member 55 can be arranged along the Z-axis direction, the number of magnets arranged by the first driving magnetic member 54 and the second driving magnetic member 55 in the X-Y plane will not affect each other, which is conducive to maximizing the number of the first driving magnetic member 54 and the second driving magnetic member 55.

[0603] It can be understood that since the driving coil 53 is fixed to the fixed carrier 51 and the first driving magnetic member 54 and the second driving magnetic member 55 are both fixed to the movable carrier 52, the anti-shake motor 50 of this embodiment is a moving magnet motor. In this way, compared with a moving coil motor, the electrical connection method of the driving coil 53 in this embodiment is simpler.

[0604] It can be understood that in the "pyramid" stacked anti-shake motor architecture of the present application, the second driving coil 532 is arranged in the middle layer of the tower and a set of symmetrically connected series reverse coils (the third driving coil 533) is added to achieve rotation compensation to solve the image rotation problem.

[0605] It can be understood that since the driving coil 53 is located between the first driving magnetic member 54 and the second driving magnetic member 55, and the first driving magnetic member 54 and the second driving magnetic member 55 are spaced far apart, it is beneficial to reduce the magnetic induction line crosstalk between the first driving magnetic member 54 and the second driving magnetic member 55 and ensure the utilization rate of the magnetic induction lines of the first driving magnetic member 54 and the second driving magnetic member 55.

[0606] Figure 76 is Figure 52 The layout schematic diagram of the second driving coil 532 and the third driving coil 533 shown in another embodiment.

[0607] such as Figure 76As shown, the number of the third driving coils 533 is multiple. The multiple third driving coils 533 are located on the same side of the second driving coil 532. In one embodiment, the multiple third driving coils 533 are located on the same side of the second driving coil 532 in the width direction.

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

[0609] Exemplarily, the two third driving coils 533 are arranged in sequence along the first direction X.

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

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

[0612] Exemplarily, the first sub-driving magnetic member 551 includes at least three polarity directions with opposite directions ( Figure 76 shown by the dotted lines with arrows in the figure), and the adjacent two polarity directions are opposite. The polarity direction of the first sub-driving magnetic member 551 can be perpendicular to the winding plane of the second driving coil 532. Among them, the coils in two regions of one third driving coil 533 can respectively correspond to the first polarity direction and the second polarity direction of the first sub-driving magnetic member 551. The coils in two regions of the other third driving coil 533 can respectively correspond to the second polarity direction and the third polarity direction of the first sub-driving magnetic member 551. It can be understood that the middle magnet of the first sub-driving magnetic member 551 can be oppositely arranged with the two third driving coils 533 at the same time. Therefore, the two third driving coils 533 can share the middle magnet of the first sub-driving magnetic member 551.

[0613] It can be understood that Figure 76 only one kind of three polarity directions of the first sub-driving magnetic member 551 is schematically given. In other embodiments, the polarity direction in the middle of the first sub-driving magnetic member 551 and the polarity directions on both sides can be swapped.

[0614] It can be understood that the anti-shake motor 50 in this embodiment can also be applied to the image sensor assembly 101 mentioned above. Specifically, it will not be elaborated here.

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