Anti-shake motor and related products thereof

[0001] The present application claims priority to the Chinese patent application No. 202410983030.2, filed on July 19, 2024, with the State Intellectual Property Office of China, entitled "Anti-shake motor and related products thereof", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of camera, in particular to an anti-shake motor and related products thereof. BACKGROUND

[0003] With the popularity and development of smart phones, mobile phone photography has become a common shooting method, and users have increasingly high requirements for the shooting quality of electronic devices. Currently, long focal lenses on the market usually adopt a periscopic structure to achieve miniaturization. The periscopic structure usually includes a light folding element and a lens group arranged from an object side to an image side, and the light folding element is driven to move by an anti-shake motor to achieve optical image stabilization. However, the current anti-shake motor has a high focal point deviation, especially in the case of a large aperture, which leads to poor final image quality. SUMMARY

[0004] The embodiments of the present application provide an anti-shake motor and related products thereof, aiming to provide an anti-shake motor with a small focal point deviation and related products thereof.

[0005] In a first aspect, an anti-shake motor is provided. The anti-shake motor has an entrance pupil and an exit pupil. The anti-shake motor includes a base, a carrier including a mounting slope, a mounting side of the mounting slope facing the entrance pupil and the exit pupil, the mounting side being used for mounting an anti-shake lens group, a guide bracket movably connected between the base and the carrier, a first driving mechanism for driving the carrier to rotate relative to the guide bracket about a first axis, the first axis being parallel to the mounting slope, and a second driving mechanism for driving the guide bracket and the carrier to rotate relative to the base about a second axis. Wherein, light is incident into the anti-shake motor from the entrance pupil along a first direction, and after being reflected by the anti-shake lens group, the light is emitted from the anti-shake motor along a second direction from the exit pupil, the first direction intersects the second direction, the first axis is located on a side of the mounting slope opposite to the mounting side, and is perpendicular to a plane in which the first direction and the second direction lie, the second axis passes through the mounting slope, and is parallel to the second direction.

[0006] It can be understood that, compared with some anti-shake motors, the carrier drives the anti-shake lens group to rotate relative to the base around the first axis, and the guide bracket drives the carrier and the anti-shake lens group to rotate relative to the base around the second axis to realize the optical image stabilization function. Among them, the first axis is perpendicular to the plane where the first direction and the second direction are located, and is located on the installation slope of the carrier. The second axis is parallel to the first direction. This makes the anti-shake motor drive the anti-shake lens group to rotate around the second axis for optical image stabilization, and the focal point offset is large, the modulation transfer function of the entire camera module decreases greatly, the anti-shake precision is low, and the imaging quality is affected.

[0007] In the anti-shake motor of the embodiment, the second axis is parallel to the second direction. In this way, when the carrier of the anti-shake motor drives the anti-shake lens group to rotate around the second axis, the exit surface of the anti-shake assembly can always be perpendicular to the light exit axis, thereby effectively reducing the inclination angle between the anti-shake assembly and the focusing assembly, reducing the focal point offset, and being beneficial to improve the anti-shake precision of the entire camera module, the optical quality of the camera module is high, and the imaging quality is improved. At the same time, the first axis of the anti-shake motor in the embodiment is located on the side of the installation slope away from the installation side. When the anti-shake lens group has a negative optical power, the system focal point of the anti-shake lens group can be located on the side of the installation slope away from the installation side. That is, the system focal point of the anti-shake lens group and the first axis can be located on the side of the installation slope away from the installation side. In this way, the distance between the first axis and the system focal point of the anti-shake lens group is close, and when the mover of the anti-shake motor drives the anti-shake lens group to rotate around the first axis, the focal point offset is small, thereby effectively reducing the influence of focal point offset on the modulation transfer function, being beneficial to improve the anti-shake precision of the entire camera module, and improving the imaging quality.

[0008] In other words, by setting the first axis perpendicular to the plane where the first direction and the second direction are located, the second axis parallel to the second direction, and the first axis on the side of the installation slope away from the installation side, the anti-shake motor in the embodiment can effectively improve the anti-shake precision of the entire anti-shake motor, reduce the influence on the modulation transfer function, and be beneficial to improve the imaging quality of the camera module.

The third part is located on the side of the carrier away from the light exit hole, and is movably connected with the base. The first part and the second part are located on the side of the third part facing the carrier, and are movably connected with the carrier. In this way, by arranging the third part of the guide bracket between the base and the carrier, the first axis can be arranged on the side of the installation slope away from the installation side. At the same time, the overall structure of the guide bracket, the carrier and the base is compact, which is beneficial to realize the miniaturization of the anti-shake motor.

[0010] In a possible implementation, the carrier is located between the first part and the second part. In this way, the structure between the carrier and the guide bracket is relatively compact, which facilitates the miniaturization of the anti-shake motor.

[0011] In a possible implementation, the carrier is provided with a first connecting portion and a second connecting portion on a side away from the light exit hole, and the first connecting portion and the second connecting portion are arranged in a direction parallel to the first axis. The anti-shake motor further includes a first set of support members, and the first set of support members includes a plurality of first support members. Some of the first support members are connected between the first connecting portion and the first part, and the other first support members are connected between the second connecting portion and the second part. In this way, the first connecting portion of the carrier can be movably connected to the guide bracket through some of the first support members, and the second connecting portion can be movably connected to the guide bracket through the other first support members, so as to realize the relative movement between the carrier and the guide bracket.

[0012] In a possible implementation, the carrier further includes a support portion, a first side wall, and a second side wall. The first side wall and the second side wall are arranged opposite to and spaced from each other, and the arrangement direction of the first side wall and the second side wall is parallel to the first axis. The support portion is fixedly connected between the first side wall and the second side wall. The support portion, the first side wall, and the second side wall enclose a mounting space. A surface of the support portion facing the mounting space constitutes a mounting inclined surface of the carrier. The mounting space is used for mounting an anti-shake lens group, and the mounting space is located on a mounting side of the mounting inclined surface. The first connecting portion of the carrier is located on a side of the first side wall away from the second side wall, and is fixedly connected to an end of the first side wall away from the light exit hole. The second connecting portion of the carrier is located on a side of the second side wall away from the first side wall, and is fixedly connected to an end of the second side wall away from the light exit hole. In this way, the carrier can form a semi-enclosed structure, so as to better carry the anti-shake lens group. Meanwhile, the first connecting portion and the second connecting portion can be arranged away from the light exit hole, so as to facilitate the arrangement of the first axis on a side of the mounting inclined surface away from the mounting side, and improve the anti-shake precision.

[0013] In a possible implementation, the first part semi-encloses the first connecting portion, and the second part semi-encloses the second connecting portion. Alternatively, the first connecting portion semi-encloses the first part, and the second connecting portion semi-encloses the second part. In this way, the structure of the first part and the first connecting portion is relatively compact, and the structure between the second part and the second connecting portion is relatively compact, which facilitates the miniaturization of the anti-shake motor.

[0014] In a possible implementation, the first part is provided with a first notch on a side close to the light exit hole, and the first connecting portion is mounted in the first notch. In this way, the structure of the first part and the first connecting portion is relatively compact, which facilitates the miniaturization of the anti-shake motor.

[0015] In a possible implementation, the plurality of first support members include a plurality of first balls and a plurality of second balls, the first connecting portion is rotationally connected to the first part by the plurality of first balls, and the second connecting portion is rotationally connected to the second part by the plurality of second balls; a center of a circle in which a plurality of ball centers of the plurality of first balls are located is a first rotation center, a center of a circle in which a plurality of ball centers of the plurality of second balls are located is a second rotation center, and a line connecting the first rotation center and the second rotation center coincides with the first shaft. In this way, the carrier is rotationally connected to the guide bracket by the first balls and the second balls, which is beneficial to reduce the motion friction between the carrier and the guide bracket and reduce power consumption.

[0016] In a possible implementation, the plurality of first support members include a first ball and a second ball, the first connecting portion is rotationally connected to the first part by the first ball, the second connecting portion is rotationally connected to the second part by the second ball, and a line connecting a ball center of the first ball and a ball center of the second ball coincides with the first shaft; or, the first ball is fixedly connected to the first connecting portion, a contact point of the first ball and the first part is a first contact point, the second ball is fixedly connected to the second connecting portion, and a contact point of the second ball and the second part is a second contact point, a line connecting the first contact point and the second contact point coincides with the first shaft; or, the first ball is fixedly connected to the first part, a contact point of the first ball and the first connecting portion is a third contact point, the second ball is fixedly connected to the second part, and a contact point of the second ball and the second connecting portion is a fourth contact point, a line connecting the third contact point and the fourth contact point coincides with the first shaft. In this way, the carrier is rotationally connected to the guide bracket by the first ball and the second ball, which is beneficial to reduce the motion friction between the carrier and the guide bracket and save power consumption.

[0017] In a possible implementation, the anti-shake motor further includes a second set of support members, a third part of the guide bracket is rotationally connected to the base by the second set of support members, a center point of the second set of support members is located on a side of the mounting slope away from the mounting side and on the second shaft. In this way, the center point of the second set of support members is relatively close to the second shaft, which is beneficial to improve the anti-shake precision.

[0018] In a possible implementation, the second set of support members include at least three third balls, the third part is rotationally connected to the base by the plurality of third balls, and ball centers of the plurality of third balls are located on a same plane; the second shaft is perpendicular to the plane in which the plurality of ball centers of the plurality of third balls are located and passes through a center of a circle in which the plurality of ball centers of the plurality of third balls are located. In this way, the second shaft is perpendicular to the plane in which the plurality of ball centers of the plurality of third balls are located, which is beneficial to improve the anti-shake precision of the anti-shake motor.

[0019] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, a first set of magnetic pieces, and a second set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base. The first set of magnetic pieces is fixed to the carrier and located on a side of the carrier away from the light inlet. The winding plane of the first driving coil is perpendicular to the first direction, and the first set of magnetic pieces is arranged opposite to the first driving coil. The second set of magnetic pieces includes a first sub-magnetic piece and a second sub-magnetic piece. The first sub-magnetic piece and the second sub-magnetic piece are both fixed to the carrier. The arrangement direction of the first sub-magnetic piece, the mounting slope, and the second sub-magnetic piece is parallel to the first axis. The second driving coil includes a first coil and a second coil. The first coil is arranged opposite to the first sub-magnetic piece, and the second coil is arranged opposite to the second sub-magnetic piece. The first driving coil and the first set of magnetic pieces constitute a first driving mechanism, and the second driving coil and the second set of magnetic pieces constitute a second driving mechanism. Alternatively, the first driving coil and the first set of magnetic pieces constitute a second driving mechanism, and the second driving coil and the second set of magnetic pieces constitute a first driving mechanism. In this way, the multiple sets of magnetic pieces used to constitute the driving mechanism in the anti-shake motor are arranged on the carrier, so that integrated transmission can be implemented, and the actuation smoothness of the anti-shake motor when performing anti-shake is improved.

[0020] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, and a second set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base. The second set of magnetic pieces includes a first sub-magnetic piece and a second sub-magnetic piece. The first sub-magnetic piece and the second sub-magnetic piece are both fixed to the carrier. The arrangement direction of the first sub-magnetic piece, the mounting slope, and the second sub-magnetic piece is parallel to the first axis. The first driving coil includes a third coil and a fourth coil. The second driving coil includes a first coil and a second coil. The third coil and the first coil are both arranged opposite to the first sub-magnetic piece. The fourth coil and the second coil are both arranged opposite to the second sub-magnetic piece. The second set of magnetic pieces and the first driving coil jointly constitute a first driving mechanism. The second set of magnetic pieces and the second driving coil jointly constitute a second driving mechanism.

[0021] In this way, compared with the anti-shake motor in some embodiments, two sets of magnetic components are arranged to cooperate with two sets of driving coils respectively to drive the carrier to move around the first axis and the second axis respectively, so that the anti-shake motor has more components and has a high manufacturing cost. In the anti-shake motor in the embodiment, only one set of magnetic components is arranged to drive the carrier to move, and the first driving coil and the second driving coil can share the same set of magnetic components, so as to drive the carrier to rotate around the first axis and the second axis respectively, thereby effectively reducing the number of components of the anti-shake motor. At the same time, the weight of the rotor of the anti-shake motor can also be reduced. Under the condition that the total weight of the rotor and the anti-shake lens group is the same, the anti-shake motor in the embodiment can generate greater thrust for anti-shake and realize large-angle anti-shake. Under the condition that the anti-shake angle is the same, the rotor in the embodiment can carry a heavier anti-shake lens group, which is beneficial to improve the optical quality of the entire camera module.

[0022] In a possible implementation, the anti-shake motor further includes a first magnetic attraction component and a second magnetic attraction component, both of which are fixed to the base. The first magnetic attraction component is located on the side of the first coil away from the first sub-magnetic component, and the second magnetic attraction component is located on the side of the second coil away from the second sub-magnetic component. In this way, when the carrier rotates around the first axis relative to the base, the first magnetic attraction component and the first sub-magnetic component can generate a magnetic attraction restoring force along the first direction Z, and the second magnetic attraction component and the second sub-magnetic component can generate a magnetic attraction restoring force along the first direction, and the directions of the two magnetic attraction restoring forces are the same, thereby generating a resistance torque around the first axis, which is beneficial to realize fast closed-loop control when the carrier rotates around the first axis. When the carrier rotates around the second axis relative to the base, the first magnetic attraction component and the first sub-magnetic component can generate a magnetic attraction restoring force along the first direction Z, and the second magnetic attraction component and the second sub-magnetic component can generate a magnetic attraction restoring force along the first direction, and the directions of the two magnetic attraction restoring forces are opposite, thereby generating a resistance torque around the second axis, which is beneficial to realize fast closed-loop control when the carrier rotates around the second axis.

[0023] In a possible implementation, the anti-shake motor further includes a first position sensor and a second position sensor, both of which are fixed to the base. The arrangement direction of the first position sensor is parallel to the first axis, and the arrangement direction of the second position sensor is parallel to the first axis. In this way, the first position sensor and the second position sensor can be used to detect the angle of rotation of the carrier around the first axis, so as to improve the anti-shake precision of the anti-shake motor.

[0024] In a possible implementation, the first position sensor comprises a first input end, a first positive output end and a first negative output end, the second position sensor comprises a second input end, a second positive output end and a second negative output end, and the first input end is connected in parallel with the second input end; the polarization direction of the first sub-magnetic piece is opposite to the polarization direction of the second sub-magnetic piece, the first positive output end is connected in parallel with the second negative output end, and the first negative output end is connected in parallel with the second positive output end; or, the polarization direction of the first sub-magnetic piece is opposite to the polarization direction of the second sub-magnetic piece, the first positive output end is connected in parallel with the second positive output end, and the first negative output end is connected in parallel with the second negative output end. In this way, the first position sensor and the second position sensor can reduce the induction crosstalk caused by the fact that the first group of magnetic pieces and the second group of magnetic pieces are both mounted on the carrier through differential operation, offset the influence caused by the fact that the rotation of the carrier around the first axis causes the magnetic field of the second group of magnetic pieces to change on the first position sensor and the second position sensor, thereby improving the control accuracy of the anti-shake motor and improving the anti-shake accuracy.

[0025] In a possible implementation, the anti-shake motor further comprises a third group of magnetic pieces, the third group of magnetic pieces is located on the side of the carrier away from the light exit hole and is fixed to the carrier, the third part of the guide bracket is provided with a relief hole, and the third group of magnetic pieces is exposed relative to the relief hole; the anti-shake motor further comprises a third position sensor, the third position sensor is fixed to the base and is arranged opposite to the third group of magnetic pieces.

[0026] It can be understood that a general anti-shake motor usually arranges the third position sensor on the side of the carrier away from the light entrance hole to be arranged opposite to the first group of magnetic pieces and detects the angle of rotation of the carrier around the first axis by detecting the change of the magnetic field of the first group of magnetic pieces through the third position sensor. However, such an arrangement makes the distance between the third position sensor and the second axis relatively large, and when the carrier rotates around the second axis, the displacement of the third position sensor is relatively large, which causes the third position sensor to be greatly interfered by the magnetic field when the carrier rotates around the second axis, thereby reducing the detection accuracy of the third position sensor when detecting the angle of rotation of the carrier around the first axis. The anti-shake motor in the embodiment further comprises a third group of magnetic pieces. The third group of magnetic pieces can be fixed to the side of the carrier away from the light exit hole. The third position sensor is fixed to the base. In this way, the distance between the third position sensor and the second axis is relatively small, thereby reducing the displacement of the third position sensor when the carrier rotates around the second axis, effectively improving the detection accuracy of the third position sensor, and improving the anti-shake accuracy of the anti-shake motor.

[0027] In a possible implementation, the second axis passes through the relief hole. In this way, the second axis can pass through the third position sensor and the third group of magnetic pieces, which is conducive to improving the detection accuracy of the third position sensor and improving the anti-shake accuracy of the anti-shake motor.

[0028] In a possible implementation, the anti-shake motor further includes a fourth set of magnetic elements and a third magnetic attraction element. The fourth set of magnetic elements is located on a side of the carrier opposite to the light exit hole and is fixed to the carrier. The third magnetic attraction element is fixed to the base. The arrangement direction of the third magnetic attraction element is parallel to the second direction. The carrier is pressed against the guide bracket under the action of the fourth set of magnetic elements and the third magnetic attraction element. In this way, the fourth set of magnetic elements can cooperate with the third magnetic attraction element to generate a magnetic attraction force in the second direction, thereby providing a pre-pressure for the carrier in the second direction. The carrier can press the guide bracket under the action of the fourth set of magnetic elements and the third magnetic attraction element, so that the plurality of first support elements can maintain contact with the carrier and the guide bracket, and the plurality of second support elements can maintain contact with the guide bracket and the base.

[0029] In a second aspect, an anti-shake assembly is provided. The anti-shake assembly includes an anti-shake lens group and the anti-shake motor described above. The anti-shake lens group is mounted on the mounting side of the carrier of the anti-shake motor. The anti-shake lens group has an entrance light axis and an exit light axis. The entrance light axis is parallel to the first direction, and the exit light axis is parallel to the second direction.

[0030] It can be understood that the second shaft of the anti-shake motor in the embodiment is parallel to the second direction. In this way, when the carrier of the anti-shake motor drives the anti-shake lens group to rotate around the second shaft, the exit surface of the anti-shake assembly can always be perpendicular to the exit light axis, thereby effectively reducing the inclination angle between the anti-shake assembly and the focusing assembly, reducing the displacement of the focal point, and improving the anti-shake precision of the entire camera module, the optical quality of the camera module is high, and the imaging quality is improved.

[0031] In other words, by arranging the first shaft perpendicular to the plane in which the first direction and the second direction lie, the second shaft parallel to the second direction, and the first shaft on the side of the mounting slope opposite to the mounting side, the anti-shake motor in the embodiment can effectively improve the anti-shake precision of the entire anti-shake motor, reduce the influence on the modulation transfer function, and improve the imaging quality of the camera module.

[0032] In a possible implementation, the anti-shake lens group includes an optical folding element and at least one lens. The anti-shake lens group has a negative optical power. It can be understood that the anti-shake lens group in the embodiment has a negative optical power, and the system focal point of the anti-shake lens group can be located on the side of the mounting slope opposite to the mounting side. That is, the system focal point of the anti-shake lens group and the first shaft can both be located on the side of the mounting slope opposite to the mounting side. In this way, the distance between the first shaft and the system focal point of the anti-shake lens group is relatively short. When the mover of the anti-shake motor drives the anti-shake lens group to rotate around the first shaft, the displacement of the focal point is relatively small, thereby effectively reducing the influence of the focal point displacement on the modulation transfer function, improving the anti-shake precision of the entire camera module, and improving the imaging quality.

[0033] In a possible implementation, the anti-shake lens group includes an optical folding element, a first lens, and a second lens, the optical folding element is fixed to the mounting side of the mounting slope, the first lens is located on the light-in side of the optical folding element, and the second lens is located on the light-out side of the optical folding element, the first lens has positive optical power, and the second lens has negative optical power.

[0034] In this way, the first lens can have a converging effect, the first lens can make as much external light as possible enter the optical folding element, so that the light-in amount of the entire anti-shake lens group can be improved, and the light-in amount of the subsequent focusing assembly can be improved. The second lens has a diverging effect, the second lens can make as much light as possible emitted by the optical folding element diverge, so that the light-out amount of the entire anti-shake lens group can be improved, and the light-in amount of the subsequent focusing assembly can be improved. In addition, the second lens has negative optical power, and the system focal point of the anti-shake lens group is far away from the imaging side. In this way, in the case that the focal length of the camera module is constant, the system focal point of the anti-shake lens group is far away from the imaging side, which is beneficial to shorten the module length of the camera module, thereby saving the internal space of the electronic device.

[0035] In a third aspect, an anti-shake assembly is provided. The anti-shake assembly includes an anti-shake lens group and an anti-shake motor, the anti-shake lens group is mounted on the anti-shake motor, the anti-shake lens group has negative optical power, the anti-shake motor has a light-in hole and a light-out hole, the anti-shake motor includes a base, a carrier movably connected to the base, the carrier includes a mounting slope, a mounting side of the mounting slope facing the side of the light-in hole and the light-out hole is used to mount the anti-shake lens group, and a first driving mechanism used to drive the carrier to rotate relative to the base around a first axis, the first axis is parallel to the mounting slope; wherein the first axis is perpendicular to a plane in which a light-in axis and a light-out axis of the anti-shake lens group are located.

[0036] It can be understood that the anti-shake lens group in the embodiment has negative optical power, and the system focal point of the anti-shake lens group can be located on the side of the mounting slope away from the mounting side. That is, the system focal point of the anti-shake lens group and the first axis can be located on the side of the mounting slope away from the mounting side. In this way, the distance between the first axis and the system focal point of the anti-shake lens group is relatively short, when the mover of the anti-shake motor drives the anti-shake lens group to rotate around the first axis, the shift amount of the focal point is relatively small, so that the influence of the focal point shift on the modulation transfer function can be effectively reduced, which is beneficial to improve the anti-shake precision of the entire camera module and improve the imaging quality.

[0037] In a possible implementation, the anti-shake lens group includes an optical folding element, a first lens, and a second lens, the optical folding element is fixed to the mounting side of the mounting slope, the first lens is located on the light-in side of the optical folding element, and the second lens is located on the light-out side of the optical folding element, the first lens has positive optical power, and the second lens has negative optical power.

[0038] In this way, the first lens can have a condensing effect, the first lens can make as much external light as possible enter the optical folding element, so that the light entering amount of the entire anti-shake lens group can be improved, and the light entering amount of the subsequent focusing assembly can be improved. The second lens has a diverging effect, the second lens can diverge as much light as possible emitted by the optical folding element, so that the light exiting amount of the entire anti-shake lens group can be improved, and the light entering amount of the subsequent focusing assembly can be improved. In addition, the second lens has a negative focal power, and the system focal point of the anti-shake lens group is away from the imaging side. In this way, under the condition that the focal length of the camera module is constant, the system focal point of the anti-shake lens group is away from the imaging side, which is beneficial to shorten the module length of the camera module, thereby saving the internal space of the electronic device.

[0039] In a possible implementation, the anti-shake motor further includes a guide bracket and a second driving mechanism. The guide bracket is movably connected between the base and the carrier. The second driving mechanism is configured to drive the guide bracket and the carrier to rotate relative to the base about a second axis. The second axis passes through the mounting slope and is parallel to the light exiting axis of the anti-shake lens group.

[0040] It can be understood that the second axis of the anti-shake motor in the embodiment is parallel to the second direction. In this way, when the carrier of the anti-shake motor drives the anti-shake lens group to rotate about the second axis, the exit surface of the anti-shake assembly can always be perpendicular to the light exiting axis, so that the inclination angle between the anti-shake assembly and the focusing assembly can be effectively reduced, the focal point offset amount can be reduced, the anti-shake precision of the entire camera module can be improved, the optical quality of the camera module is higher, and the imaging quality can be improved.

[0041] In other words, by arranging the first axis to be perpendicular to the plane in which the first direction and the second direction lie, the second axis to be parallel to the second direction, and the first axis to be located on the side of the mounting slope away from the mounting side, the anti-shake motor in the embodiment can effectively improve the anti-shake precision of the entire anti-shake motor, reduce the influence on the modulation transfer function, and improve the imaging quality of the camera module.

[0042] In a possible implementation, the guide bracket includes a first part, a second part, and a third part. The first part and the second part are oppositely arranged, and both the first part and the second part are fixedly connected to the third part. The third part is located on the side of the carrier away from the light exiting hole and movably connected to the base. The first part and the second part are located on the side of the third part facing the carrier and movably connected to the carrier. In this way, by arranging the third part of the guide bracket between the base and the carrier, the first axis can be arranged on the side of the mounting slope away from the mounting side. At the same time, the overall structure among the guide bracket, the carrier, and the base is relatively compact, which is beneficial to realize the miniaturization of the anti-shake motor.

[0043] In a possible implementation, the carrier is located between the first part and the second part. In this way, the structure between the carrier and the guide bracket is relatively compact, which facilitates the miniaturization of the anti-shake motor.

In this way, the first connecting portion of the carrier can be movably connected to the guide bracket through part of the first support members, and the second connecting portion can be movably connected to the guide bracket through another part of the first support members, so as to realize the relative movement between the carrier and the guide bracket.

In this way, the carrier can form a semi-enclosed structure, so as to better carry the anti-shake lens group. Meanwhile, the first connecting portion and the second connecting portion can be arranged away from the light exit hole, so as to facilitate the arrangement of the first axis on a side of the mounting inclined surface away from the mounting side, and improve the anti-shake precision.

[0046] In a possible implementation, the first part semi-encloses the first connecting portion, and the second part semi-encloses the second connecting portion; or, the first connecting portion semi-encloses the first part, and the second connecting portion semi-encloses the second part. In this way, the structure of the first part and the first connecting portion is relatively compact, and the structure between the second part and the second connecting portion is relatively compact, which facilitates the miniaturization of the anti-shake motor.

[0047] In a possible implementation, the first part is provided with a first notch on a side close to the light exit hole, and the first connecting portion is mounted in the first notch. In this way, the structure of the first part and the first connecting portion is relatively compact, which facilitates the miniaturization of the anti-shake motor.

[0048] In a possible implementation manner, the anti-shake motor further includes a second set of support members, a third part of the guide bracket is rotationally connected to the base through the second set of support members, a center point of the second set of support members is located on a side of the mounting slope away from the mounting side and on the second shaft. In this way, the center point of the second set of support members is close to the second shaft, which is beneficial to improving the anti-shake precision.

[0049] In a fourth aspect, an anti-shake motor is provided. The anti-shake motor has a light inlet and a light outlet. The anti-shake motor includes a base; a carrier including a mounting slope, a mounting side of the mounting slope facing the light inlet and the light outlet is used for mounting an anti-shake lens group; a guide bracket movably connected between the base and the carrier; a first driving mechanism used for driving the carrier to rotate relative to the base about a first shaft, the first shaft being parallel to the mounting slope; a second driving mechanism used for driving the guide bracket and the carrier to rotate relative to the base about a second shaft; and a first detection assembly used for detecting an angle of rotation of the carrier about the first shaft, the first detection assembly including a first position sensor, a second position sensor, a first magnetic member and a second magnetic member, the first position sensor and the second position sensor are both fixed to the base, the first magnetic member and the second magnetic member are both fixed to the carrier, and the first magnetic member, the mounting slope and the second magnetic member are arranged in parallel to the first shaft; wherein light enters the anti-shake motor from the light inlet along a first direction, and after being reflected by the anti-shake lens group, the light exits the anti-shake motor from the light outlet along a second direction, the first direction intersects the second direction, the first shaft is located on the mounting side of the mounting slope and is perpendicular to a plane on which the first direction and the second direction lie; wherein the first position sensor includes a first input end, a first positive output end and a first negative output end, the second position sensor includes a second input end, a second positive output end and a second negative output end, and the first input end and the second input end are connected in parallel; a polarization direction of the first magnetic member is opposite to a polarization direction of the second magnetic member, the first positive output end and the second negative output end are connected in parallel, and the first negative output end and the second positive output end are connected in parallel; or, the polarization direction of the first magnetic member is opposite to the polarization direction of the second magnetic member, the first positive output end and the second positive output end are connected in parallel, and the first negative output end and the second negative output end are connected in parallel.

[0050] In this way, the first position sensor and the second position sensor can reduce the induction crosstalk problem caused by the fact that the first set of magnetic members and the second set of magnetic members are both mounted on the carrier through differential operation, offset the influence of the change of the magnetic field of the second set of magnetic members caused by the rotation of the carrier about the first shaft on the first position sensor and the second position sensor, thereby improving the control precision of the anti-shake motor and improving the anti-shake precision.

[0051] In a possible implementation, the carrier is provided with a first connecting portion and a second connecting portion on a side close to the light exit hole, and the first connecting portion and the second connecting portion are arranged in a direction parallel to the first axis; the anti-shake motor further includes a first set of support members, and the first set of support members includes a plurality of first support members, part of the first support members being connected between the first connecting portion and the guide support, and another part of the first support members being connected between the second connecting portion and the guide support. In this way, the first connecting portion of the carrier can be movably connected to the guide support through part of the first support members, and the second connecting portion can be movably connected to the guide support through another part of the first support members. Meanwhile, the first connecting portion and the second connecting portion can be arranged close to the light exit hole, so as to arrange the first axis on the mounting side of the mounting slope and improve the anti-shake precision.

[0052] In a possible implementation, the carrier further includes a support portion, a first side wall and a second side wall, the first side wall and the second side wall are arranged opposite to and spaced from each other, and the arrangement direction of the first side wall and the second side wall is parallel to the first axis; the support portion is fixedly connected between the first side wall and the second side wall, and the support portion, the first side wall and the second side wall enclose a mounting space, a surface of the support portion facing the mounting space constitutes the mounting slope of the carrier, and the mounting space is used to mount at least part of the anti-shake lens group, and the mounting space is located on the mounting side of the mounting slope; the first connecting portion of the carrier is located on a side of the first side wall away from the second side wall, and is fixedly connected to an end of the first side wall close to the light exit hole; and the second connecting portion of the carrier is located on a side of the second side wall away from the first side wall, and is fixedly connected to an end of the second side wall close to the light exit hole. In this way, the carrier can form a semi-enclosed structure, so as to better support the anti-shake lens group. Meanwhile, the first connecting portion and the second connecting portion can be arranged close to the light exit hole, so as to arrange the first axis on the mounting side of the mounting slope and improve the anti-shake precision.

[0053] In a possible implementation, the guide support includes a first part and a second part arranged opposite to each other, the first part is movably connected between the first connecting portion and the base, and the second part is movably connected between the second connecting portion and the base; the anti-shake motor further includes a second set of support members, and the second set of support members includes a plurality of second support members, the first part is rotatably connected to the base through part of the second support members, and the second part is rotatably connected to the base through another part of the second support members, and a center point of the second set of support members is located on the mounting side. In this way, when the anti-shake lens group is mounted on the anti-shake motor, the center point of the second set of support members is located on the mounting side, and the center point of the second set of support members is relatively close to the center of gravity of the anti-shake lens group, the carrier and the guide support as a whole. In this way, on the one hand, the anti-interference capability of the anti-shake motor when rotating around the second axis for anti-shake can be effectively improved; on the other hand, the power consumption of the anti-shake motor can be reduced, which is conducive to prolonging the endurance time of the electronic device and improving the user experience.

[0054] In a possible implementation, the first part semi-surrounds the first connecting part, and the second part semi-surrounds the second connecting part; or, the first connecting part semi-surrounds the first part, and the second connecting part semi-surrounds the second part. In this way, the structure of the first part and the first connecting part is relatively compact, and the structure of the second part and the second connecting part is relatively compact, which is beneficial to miniaturization of the anti-shake motor.

[0055] In a possible implementation, the first part is provided with a first notch on a side close to the light-out hole, and the first connecting part is mounted in the first notch. In this way, the structure of the first part and the first connecting part is relatively compact, which is beneficial to miniaturization of the anti-shake motor.

[0056] In a possible implementation, the second support member includes at least three third balls, and the guide bracket is rotationally connected to the base through the third balls, and the centers of the third balls are located in the same plane; and the second shaft is perpendicular to the plane in which the centers of the third balls are located. In this way, the second shaft is perpendicular to the plane in which the centers of the third balls are located, which is beneficial to improving the anti-shake precision of the anti-shake motor.

[0057] In a possible implementation, the anti-shake motor further includes a second detection assembly, the second detection assembly includes a third magnetic member and a third position sensor, the third magnetic member is fixed to the carrier, and the third position sensor is fixed to the base and is arranged opposite to the third magnetic member; and the third magnetic member is located on a side of the carrier away from the light-in hole, or the third magnetic member is located on a side of the carrier away from the light-out hole.

[0058] It can be understood that, generally, the third position sensor of the anti-shake motor is arranged on a side of the carrier away from the light-in hole, to be arranged opposite to the first group of magnetic members, and to detect the angle of rotation of the carrier around the first shaft by detecting the magnetic field change of the first group of magnetic members. However, such an arrangement makes the distance between the third position sensor and the second shaft relatively large, and when the carrier rotates around the second shaft, the displacement of the third position sensor is relatively large, which causes the third position sensor to be greatly interfered by the magnetic field when the carrier rotates around the second shaft, and reduces the detection precision of the third position sensor in detecting the angle of rotation of the carrier around the first shaft. However, the anti-shake motor in the embodiment further includes a third group of magnetic members. The third group of magnetic members can be fixed to a side of the carrier away from the light-out hole. The third position sensor is fixed to the base. In this way, the distance between the third position sensor and the second shaft is relatively small, so as to reduce the displacement of the third position sensor when the carrier rotates around the second shaft, effectively improve the detection precision of the third position sensor, and improve the anti-shake precision of the anti-shake motor.

[0059] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, and a first set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base, and the first set of magnetic pieces is fixed to the carrier and located on a side of the carrier away from the light inlet. The first set of magnetic pieces is arranged opposite to the first driving coil. The second driving coil includes a first coil and a second coil. The first coil is arranged opposite to the first magnetic piece, and the second coil is arranged opposite to the second magnetic piece. The first driving coil and the first set of magnetic pieces form a first driving mechanism, and the second driving coil and the first magnetic piece and the second magnetic piece form a second driving mechanism. Alternatively, the first driving coil and the first set of magnetic pieces form a second driving mechanism, and the second driving coil and the first magnetic piece and the second magnetic piece form a first driving mechanism. In this way, the first set of magnetic pieces is located on the side of the carrier away from the light inlet, and the size of the anti-shake motor in the second direction can be saved.

[0060] In a possible implementation, the anti-shake motor further includes a first driving coil and a second driving coil. The first driving coil and the second driving coil are fixed to the base. The first driving coil includes a third coil and a fourth coil, and the second driving coil includes a first coil and a second coil. The third coil and the first coil are arranged opposite to the first magnetic piece, and the fourth coil and the second coil are arranged opposite to the second magnetic piece. The first magnetic piece and the second magnetic piece together with the first driving coil form a first driving mechanism, and the first magnetic piece and the second magnetic piece together with the second driving coil form a second driving mechanism.

[0061] In this way, compared with some embodiments in which the anti-shake motor needs to be provided with two sets of magnetic pieces to cooperate with two sets of driving coils respectively to drive the carrier to move around the first shaft and the second shaft, the number of components in the anti-shake motor is larger, and the manufacturing cost is higher. In the embodiment, only one set of magnetic pieces is needed to drive the carrier to move, and the first driving coil and the second driving coil can share the same set of magnetic pieces, so as to drive the carrier to rotate around the first shaft and the second shaft respectively, effectively reducing the number of components of the anti-shake motor. At the same time, the weight of the moving element of the anti-shake motor can also be reduced. Under the condition that the total weight of the moving element and the anti-shake lens group is the same, the anti-shake motor in the embodiment can generate greater thrust for anti-shake and realize large-angle anti-shake. Under the condition that the anti-shake angle is the same, the moving element in the embodiment can carry an anti-shake lens group with a larger weight, which is conducive to improving the optical quality of the entire camera module.

[0062] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, and a first set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base, and the first set of magnetic pieces is fixed to the carrier and located on a side of the carrier away from the light exit hole. The first set of magnetic pieces is arranged opposite to the first driving coil. The second driving coil includes a first coil and a second coil. The first coil is arranged opposite to the first magnetic piece, and the second coil is arranged opposite to the second magnetic piece. The first driving coil and the first set of magnetic pieces form a first driving mechanism, and the second driving coil and the first magnetic piece and the second magnetic piece form a second driving mechanism. Alternatively, the first driving coil and the first set of magnetic pieces form the second driving mechanism, and the second driving coil and the first magnetic piece and the second magnetic piece form the first driving mechanism. In this way, the first set of magnetic pieces can be located on the side of the carrier away from the light exit hole, which is beneficial to saving the size of the anti-shake motor in the direction of the first axis.

[0063] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, a first set of magnetic pieces, and a second set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base, and the first set of magnetic pieces and the second set of magnetic pieces are fixed to the carrier. The first set of magnetic pieces is located on a side of the carrier away from the light entrance hole, and the first driving coil is arranged opposite to the first set of magnetic pieces. The second set of magnetic pieces is located on a side of the carrier away from the light exit hole, and the second driving coil is arranged opposite to the second set of magnetic pieces. The first driving coil and the first set of magnetic pieces form a first driving mechanism, and the second driving coil and the second set of magnetic pieces form a second driving mechanism. Alternatively, the first driving coil and the first set of magnetic pieces form the second driving mechanism, and the second driving coil and the second set of magnetic pieces form the first driving mechanism. In this way, the first set of magnetic pieces is located on the side of the carrier away from the light entrance hole, which can save the size of the anti-shake motor in the second direction.

[0064] In a possible implementation, the anti-shake motor further includes a first driving coil, a second driving coil, and a first set of magnetic pieces. The first driving coil and the second driving coil are fixed to the base, and the first set of magnetic pieces is fixed to the carrier and located on a side of the carrier away from the light exit hole. The first driving coil and the second driving coil are arranged opposite to the first set of magnetic pieces. The second driving coil includes a first coil and a second coil, and the first driving coil is located between the first coil and the second coil. The first set of magnetic pieces and the first driving coil together form a first driving mechanism, and the first set of magnetic pieces and the second driving coil together form a second driving mechanism. In this way, the first set of magnetic pieces can be located on the side of the carrier away from the light exit hole, which is beneficial to saving the size of the anti-shake motor in the direction of the first axis.

[0065] In a fifth aspect, a kind of anti-shake assemblies is provided.The anti-shake assembly includes an anti-shake lens group and the anti-shake motor described above, the anti-shake lens group is installed on the mounting side of the carrier of the anti-shake motor, the anti-shake lens group has a light entrance axis and a light exit axis, the light entrance axis is parallel to the first direction, and the light exit axis is parallel to the second direction.

[0066] It can be understood that the second shaft of the anti-shake motor in the embodiment is parallel to the second direction.In this way, when the carrier of the anti-shake motor drives the anti-shake lens group to rotate around the second shaft, the exit surface of the anti-shake assembly can always be perpendicular to the light exit axis, so that the inclination angle between the anti-shake assembly and the focusing assembly can be effectively reduced, the shift amount of the focal point can be reduced, the anti-shake precision of the entire camera module can be improved, the optical quality of the camera module is high, and the imaging quality can be improved.

[0067] In other words, by setting the first shaft perpendicular to the plane where the first direction and the second direction are located, the second shaft parallel to the second direction, and the first shaft on the side of the mounting slope away from the mounting side, the anti-shake precision of the anti-shake motor as a whole can be effectively improved, the influence on the modulation transfer function can be reduced, and the imaging quality of the camera module can be improved.

[0068] In a possible implementation, the anti-shake lens group includes an optical folding element and at least one lens, and the anti-shake lens group has a positive focal power.It can be understood that the anti-shake lens group in the embodiment has a positive focal power, and the system focal point of the anti-shake lens group can be located on the mounting side of the mounting slope.In other words, the system focal point of the anti-shake lens group and the first shaft can both be located on the mounting side of the mounting slope.In this way, the distance between the first shaft and the system focal point of the anti-shake lens group is close, and when the mover of the anti-shake motor drives the anti-shake lens group to rotate around the first shaft, the shift amount of the focal point is small, so that the influence of the shift of the focal point on the modulation transfer function can be effectively reduced, the anti-shake precision of the entire camera module can be improved, and the imaging quality can be improved.

[0069] In a possible implementation, the anti-shake lens group includes an optical folding element and a first lens, the first lens is located on the light entrance side of the optical folding element, and the first lens has a positive focal power;or the anti-shake lens group includes an optical folding element, a first lens, and a second lens, the first lens is located on the light entrance side of the optical folding element, the second lens is located on the light exit side of the optical folding element, the first lens has a positive focal power, and the second lens has a negative focal power.

[0070] In this way, the first lens can have a condensing effect, the first lens can make as much external light as possible enter the optical folding element, so that the light amount of the entire anti-shake lens group can be improved, which is beneficial to improve the light amount of the subsequent focusing assembly. The second lens has a diverging effect, the second lens can diverge as much light as possible emitted by the optical folding element, so that the light amount of the entire anti-shake lens group can be improved, which is beneficial to improve the light amount of the subsequent focusing assembly. In addition, the second lens has a negative focal power, and the system focal point of the anti-shake lens group is also away from the imaging side. In this way, under the condition that the focal length of the camera module is constant, the system focal point of the anti-shake lens group is away from the imaging side, which is beneficial to shorten the module length of the camera module, thereby saving the internal space of the electronic device.

[0071] In a sixth aspect, a camera module is provided. The camera module includes an image sensor and the anti-shake assembly described above, and the image sensor is located on the light-emitting side of the anti-shake assembly.

[0155] It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings.

[0156] FIG. 1 is a structural schematic diagram of one embodiment of an electronic device 1000 provided by the present application. FIG. 2 is a cross-sectional structural schematic diagram of the electronic device 1000 shown in FIG. 1 along A-A in one embodiment.

[0157] As shown in FIGS. 1 and 2, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet, etc. The electronic device 1000 of the embodiment shown in FIG. 1 is described by taking a mobile phone as an example.

[0158] As shown in FIG. 1, the electronic device 1000 can include a camera module 100, a device housing 200, and a screen 300. The camera module 100 can be a rear camera module or a front camera module. It should be noted that FIG. 1 and the following related drawings 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 FIG. 1 and the following drawings. In addition, when the electronic device 1000 is some other form of device, the electronic device 1000 can also not include the screen 300.

[0159] For ease of description, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is the Y-axis. The thickness direction of the electronic device 1000 is the Z-axis. It can be understood that the coordinate system of the electronic device 1000 can be flexibly set according to actual needs.

[0160] In this embodiment, the device housing 200 can include a frame 201 and a back cover 202. The back cover 202 is fixed to the frame 201. For example, the back cover 202 can be fixedly connected to the frame 201 by adhesive. The back cover 202 can also be an integral structure with the frame 201, i.e., the back cover 202 and the frame 201 are an integral structure.

[0161] In addition, the screen 300 can be located on the side of the frame 201 away from the back cover 202. At this time, the screen and the back cover 202 are located on the two sides of the frame 201, respectively. The screen 300, the frame 201, and the back cover 202 together enclose the inside of the electronic device 1000. The inside of the electronic device 1000 can be used to place devices of the electronic device 1000, such as a battery, a receiver, or a microphone, etc. The screen 300 can be a flat screen or a curved screen.

[0162] For example, the camera module 100 can be a periscopic camera module. The camera module 100 can be located in the inside of the electronic device 1000. The camera module 100 can be fixed to the side of the screen 300 facing the back cover 202. The back cover 202 can be provided with a light transmission hole 203. The shape of the light transmission hole 203 is not limited to the circular shape shown in FIG. 1. The light transmission hole 203 connects the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light transmission hole 203. The camera module 100 can collect ambient light entering the inside of the electronic device 1000.

[0163] FIG. 3 is a structural schematic diagram of the anti-shake assembly 1 of the camera module 100 shown in FIG. 2 in some embodiments. FIG. 4 is an exploded structural schematic diagram of the anti-shake assembly 1 shown in FIG. 3 in some embodiments.

[0164] As shown in FIGS. 2-4, the camera module 100 can include an anti-shake assembly 1, a focusing assembly 2, and an image sensor 3. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting hole 203, and then pass through the anti-shake assembly 1 and the focusing assembly 2 in sequence, and finally be imaged on the image sensor 3. Exemplarily, the anti-shake assembly 1, the focusing assembly 2, and the image sensor 3 can be arranged along the X-axis direction in sequence.

[0165] In some embodiments, one or more lenses / prisms with reflecting function can be additionally arranged between the focusing assembly 2 and the image sensor 3 to change the propagation path of the light between the focusing assembly 2 and the image sensor 3, so that the light emitted by the focusing assembly 2 can pass through one or more reflections and finally enter the image sensor 3. In this way, the overall light path of the camera module 100 is lengthened, which is beneficial to reducing the overall module length of the camera module 100 and saving the internal space of the electronic device 1000.

[0166] Exemplarily, the anti-shake assembly 1 can include an anti-shake motor la and an anti-shake lens group lb. The anti-shake lens group lb can have a negative optical power. The anti-shake lens group lb can be mounted on the anti-shake motor la. The anti-shake motor la can drive the anti-shake lens group lb to rotate around a first axis (not shown in the figure) and / or a second axis (not shown in the figure), so as to realize optical image stabilization (OIS) of the camera module 100 and improve the imaging quality of the camera module 100.

[0167] Exemplarily, the focusing assembly 2 can include a focusing motor (not shown in the figure) and a focusing lens group (not shown in the figure). The focusing lens group can be mounted on the focusing motor. The focusing motor can control the focusing lens group to move along the optical axis direction for realizing auto focus (AF). The focusing lens group can include at least one lens. The first optical element and the focusing lens group can jointly constitute at least part of the optical system of the camera module 100.

[0168] FIG. 5 is an exploded structural schematic diagram of the anti-shake lens group lb of the anti-shake assembly 1 shown in FIG. 3 in some embodiments. FIG. 6a is a partial cross-sectional structural schematic diagram of the anti-shake assembly 1 shown in FIG. 3 along B1-B1 in one embodiment. FIG. 6b is a cross-sectional structural schematic diagram of the structure shown in FIG. 6a in another embodiment.

[0169] As shown in FIG. 5 and FIG. 6a, the anti-shake mirror group 1b can include an entrance surface 101, a reflection surface 102, and an exit surface 103. Light rays can enter the interior of the anti-shake mirror group 1b from the entrance surface 101 of the anti-shake mirror group 1b, be reflected by the reflection surface 102, and then exit from the exit surface 103. The entrance axis T1 of the anti-shake mirror group 1b can be perpendicular to the entrance surface 101. The exit axis T2 of the anti-shake mirror group 1b can be perpendicular to the exit surface 103. The system focal point of the anti-shake mirror group 1b can be located on the side of the reflection surface 102 away from the entrance surface 101 and the exit surface 103. In this embodiment, the entrance axis T1 of the anti-shake mirror group 1b can be parallel to the Z-axis direction, and the exit axis T2 can be parallel to the X-axis direction.

[0170] Exemplarily, the anti-shake mirror group 1b can include an optical folding element 104 and at least one lens. In this embodiment, the anti-shake mirror group 1b can include two lenses, for example, can include a first lens 105 and a second lens 106. The first lens 105 can be fixed on the light-entering side of the optical folding element 104. At this time, the entrance surface of the first lens 105 can constitute the entrance surface 101 of the anti-shake mirror group 1b. The second lens 106 can be fixed on the light-exiting side of the optical folding element 104. At this time, the exit surface of the second lens 106 can constitute the exit surface 103 of the anti-shake mirror group 1b. In other embodiments, the first lens 105 and / or the second lens 106 can also be a lens group, including multiple lenses.

[0171] Exemplarily, the optical folding element 104 can be a reflective triangular prism. The cross section of the optical folding element 104 can be triangular. The optical folding element 104 can include a first surface 1041, a second surface 1042, and a third surface 1043. The first surface 1041 and the third surface 1043 can be perpendicular to each other. The second surface 1042 can be connected between the first surface 1041 and the third surface 1043. The first surface 1041 can be perpendicular to the entrance axis. The third surface 1043 can be perpendicular to the exit axis. Both the first surface 1041 and the third surface 1043 can be transmission surfaces. The second surface 1042 can be a reflection surface. In this way, light rays can enter the interior of the optical folding element 104 from the first surface 1041, be reflected by the second surface 1042, and then exit from the third surface 1043. At this time, the second surface 1042 of the optical folding element 104 can constitute the reflection surface 102 of the anti-shake mirror group 1b. The third surface 1043 of the optical folding element 104 can constitute the exit surface 103 of the anti-shake mirror group 1b.

[0172] The cross section of the optical folding element 104 can be an isosceles triangle, that is, the included angle between the second surface 1042 and the first surface 1041 can be 45°, and the included angle between the second surface 1042 and the third surface 1043 can also be 45°. At this time, the deflection angle of the light after being reflected by the second surface 1042 can be 90° (as shown in FIG. 6a). In other embodiments, the included angle between the second surface 1042 and the first surface 1041 can also be other angles, which are not limited in the present application.

[0173] Exemplarily, the first lens 105 can have a positive focal power. In this way, the first lens 105 can have a converging effect, and the first lens 105 can make as much external light as possible enter the optical folding element 104, thereby improving the light intake of the entire anti-shake lens group 1b and being beneficial to improving the light intake of the subsequent focusing assembly 2. The second lens 106 can have a negative focal power. The second lens 106 can be located on the light exit side of the optical folding element 104. The second lens 106 can be fixedly connected to the third surface 1043 of the optical folding element 104 by bonding or the like. In this way, the second lens 106 has a diverging effect, and the second lens 106 can make as much light emitted by the optical folding element 104 as possible diverge, thereby improving the light exit of the entire anti-shake lens group 1b and being beneficial to improving the light intake of the subsequent focusing assembly 2. Secondly, the second lens 106 has a negative focal power, which can also make the system focal point of the anti-shake lens group 1b away from the imaging side. In this way, under the condition that the focal length of the camera module 100 is constant, the system focal point of the anti-shake lens group 1b is away from the imaging side, which is beneficial to shorten the module length of the camera module 100, thereby saving the internal space of the electronic device 1000.

[0174] In some embodiments, as shown in FIG. 6b, the optical folding element 104 can also be a reflective plane mirror. The reflective plane mirror can include a reflective surface 1044 and a mounting surface 1045 arranged opposite to each other. The reflective surface 1044 of the reflective plane mirror can be directed towards the first lens 105 and the second lens 106. The reflective surface 1044 of the optical folding element 104 can be arranged at an angle with the surface of the first lens 105 directed towards the optical folding element 104. For example, the reflective surface 1044 can be arranged at an angle of 45° with the surface of the first lens 105 directed towards the optical folding element 104. In this case, the reflective surface 1044 of the reflective plane mirror can constitute the reflective surface 102 of the anti-shake lens group lb. In this way, compared with the anti-shake assembly in which the optical folding element is a reflective triangular prism, the first surface, the second surface and the third surface of the reflective triangular prism are all solid surfaces, and the transmission of light between the first surface and the third surface is located inside the reflective triangular prism. The refractive index inside the reflective triangular prism is high, which increases the optical path requirement of the entire camera module, lengthens the focusing path of the focusing assembly, and lengthens the overall size of the module. In the present embodiment, the optical folding element 104 is a reflective plane mirror, and the reflective surface 1044 of the optical folding element 104 is exposed to air. In this way, the transmission of light between the light inlet hole 20a and the light outlet hole 20b is located in the air. The refractive index in the air is low, which is beneficial to reduce the optical path requirement of the camera module 100, thereby shortening the focusing path of the focusing assembly 2, and is beneficial to reduce the size of the module in the X-axis direction, and to realize the miniaturization of the camera module 100.

[0175] FIG. 7a is a simplified schematic diagram of the anti-shake lens group lb shown in FIG. 6a. FIG. 7b is a structural schematic diagram of the structure shown in FIG. 7a from another perspective. In order to facilitate understanding, only the optical folding element 104 and the first lens 105 of the anti-shake lens group lb are shown in FIG. 7a, and only the second surface 1042 (i.e., the reflective surface 102 of the anti-shake lens group lb) of the optical folding element 104 is shown.

[0176] As shown in FIG. 7a and FIG. 7b, the anti-shake lens group 1b can rotate (i.e., nodding motion) around the first axis R1. Wherein, the plane on which the light-incoming axis T1 and the light-outgoing axis T2 lie is the reference plane M0. The first axis R1 can be perpendicular to the light-incoming axis T1, and also perpendicular to the light-outgoing axis T2, i.e., the first axis R1 can be perpendicular to the reference plane M0. Wherein, the intersection of the light-outgoing axis T2 and the reflecting surface 102 is the first intersection G1. The straight line L1 is parallel to the light-incoming axis T1, and intersects the first axis R1. The intersection of the straight line L1 and the first axis R1 is the second intersection G2. The intersection of the light-incoming axis T1 and the incident surface 101 is the third intersection G3. The straight line L2 is parallel to the light-outgoing axis T2, and passes through the third intersection G3. The intersection of the straight line L2 and the straight line L1 is the fourth intersection G4. The fourth intersection G4 can be located on the first lens 105, or outside the first lens 105. Exemplarily, the first intersection G1, the second intersection G2, the third intersection G3, and the fourth intersection G4 can all be on the reference plane M0. The second intersection G2 can be located on the side of the reflecting surface 102 away from the incident surface 101 and the exit surface 103. It should be understood that the first axis R1 being perpendicular to the light-incoming axis T1 can be completely perpendicular, or approximately perpendicular, for example, the deviation is within 1°. The first axis R1 being perpendicular to the light-outgoing axis T2 also applies to the above definition, which will not be repeated here.

[0177] Exemplarily, the projection point of the first axis R1 on the reference plane M0 is the first point. The first point can be located in the region defined by the straight line L3, the straight line L4, and the straight line L5. Wherein, the straight line L3 and the straight line L4 are both parallel to the light-outgoing axis T2. The straight line L3 is located on the side of the light-outgoing axis T2 close to the first lens 105. The straight line L4 is located on the side of the light-outgoing axis T2 away from the first lens 105. The straight line L3 intersects the reflecting surface 102 at the k1 point. The straight line L4 intersects the reflecting surface at the k2 point. The distance of the straight line k1 and the straight line k2 to the light-outgoing axis T2 can both be 3 mm. The straight line L5 is parallel to the light-incoming axis T1. The distance of the straight line L5 to the light-incoming axis T1 can be 20 mm.

[0178] It should be noted that the region defined by the straight line L1, the straight line L2, and the straight line L3 includes the region surrounded by the straight line L1, the straight line L2, and the straight line L3, and the boundary of the straight line L1, the straight line L2, and the straight line L3. In other words, the first point can be located on the side of the reflecting surface 102 away from the imaging surface, and the distance of the first point to the light-outgoing axis T2 can be less than or equal to 3 mm. The distance of the first point to the light-incoming axis T1 in the X-axis direction can be less than or equal to 20 mm.

[0179] FIG. 8a is a simplified schematic diagram of the anti-shake mirror group 1b of the anti-shake assembly 1 rotating around the first axis R1 for anti-shake in some embodiments. FIG. 8b is a simplified schematic diagram of the anti-shake mirror group 1b rotating around the first axis R1 for anti-shake shown in FIG. 7a. It should be noted that the left side of FIG. 8a and FIG. 8b are schematic diagrams of the anti-shake mirror group 1b being shaken and the anti-shake not being turned on, and the right side of FIG. 8a and FIG. 8b are schematic diagrams of the anti-shake mirror group 1b being shaken and the anti-shake being turned on.

[0180] As shown in FIG. 7a, FIG. 8a, and FIG. 8b, when the electronic device 1000 is shaken in a direction parallel to the reference plane M0 and the anti-shake motor 1a does not turn on the anti-shake, the system focal point of the anti-shake mirror group 1b is the first original focal point P0. When the anti-shake mirror group 1b has a negative optical power, the first original focal point P0 can be located on the side of the reflecting surface 102 away from the incident surface 101 and the exit surface 103 (i.e., the left side of the reflecting surface 102 in FIG. 7a, FIG. 8a, and FIG. 8b). It should be understood that the light rays emitted by the anti-shake mirror group 1b will produce multiple focal points, i.e., the anti-shake motor 1a has multiple first original focal points P0 when the anti-shake is not turned on, and only one of the first original focal points P0 is shown here. When the electronic device 1000 is shaken in a direction parallel to the reference plane M0 and the anti-shake motor 1a turns on the anti-shake, the anti-shake motor 1a can drive the anti-shake mirror group 1b to rotate around the first axis R1 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to achieve anti-shake.

[0181] It can be understood that, in some embodiments, the first axis R1` is located on the reflecting surface 102 of the anti-shake mirror group 1b, and the distance between the first axis R1` and the first original focal point P0 is large. This makes the first focal point P1` generated by the anti-shake mirror group 1b after the anti-shake mirror group 1b rotates around the first axis R1` for anti-shake have a large offset compared to the first original focal point P0, so that the modulation transfer function (MTF) of the camera module 100 as a whole decreases greatly, affecting the imaging quality.

[0182] In the present embodiment, the first axis R1 can be located on the side of the reflecting surface 102 away from the incident surface 101 and the exit surface 103 (i.e., the left side of the reflecting surface 102 in FIG. 7a, FIG. 8a, and FIG. 8b). The distance between the first axis R1 and the first original focal point P0 is close. In this way, the first focal point P1 generated by the anti-shake mirror group 1b after the anti-shake mirror group 1b rotates around the first axis R1 for anti-shake has a small offset compared to the first original focal point P0, which is beneficial to improve the anti-shake precision of the camera module 100, while reducing the impact of focal point offset on the modulation transfer function, which is beneficial to improve the imaging quality.

[0183] FIG. 9a is a simplified schematic diagram of the anti-shake lens group 1b of the anti-shake assembly 1 rotating around the second axis R2 for anti-shake in some embodiments. FIG. 9b is a simplified schematic diagram of the anti-shake lens group 1b rotating around the second axis R2 for anti-shake shown in FIG. 7a. It should be noted that the left side of FIGS. 9a and 9b are schematic diagrams of the anti-shake lens group 1b shaking and the anti-shake not being turned on, and the right side of FIGS. 9a and 9b are schematic diagrams of the anti-shake lens group 1b shaking and the anti-shake being turned on.

[0184] As shown in FIGS. 7a, 9a, and 9b, the anti-shake lens group 1b can rotate around the second axis R2 (i.e., a pan motion). The second axis R2 can be parallel to the light-outgoing axis T2, i.e., the second axis R2 can be parallel to the X-axis direction. The distance between the second axis R2 and the light-outgoing axis T2 can be less than or equal to 3 mm, i.e., the second axis R2 can be located within a cylindrical space with the light-outgoing axis T2 as the central axis and a radius of 3 mm. Exemplarily, the second axis R2 can coincide with the light-outgoing axis T2. It should be understood that the second axis R2 being parallel to the light-outgoing axis T2 can be completely parallel or approximately parallel, for example, within a deviation of 1°. When the electronic device 1000 shakes in a direction parallel to the reference plane M0 and the anti-shake lens group 1b does not turn on the anti-shake, the exit surface M1 of the anti-shake assembly 1 can be parallel to the entrance surface M2 of the focusing assembly 2. The exit surface M1 of the anti-shake assembly 1 is parallel to the exit surface 103 of the anti-shake lens group 1b. When the anti-shake motor 1a turns on the anti-shake, the anti-shake motor 1a can drive the anti-shake lens group 1b to rotate around the second axis R2 to compensate for the image drift on the image plane caused by the shaking of the electronic device 1000, so as to achieve anti-shake.

[0185] It can be understood that in some embodiments, the second axis R2` coincides with the light-ingoing axis T1 of the anti-shake lens group 1b, i.e., the second axis R2` can be parallel to the Z-axis direction. However, when the anti-shake lens group 1b rotates around the second axis R2`, the exit surface M1` of the anti-shake assembly 1 will form an angle with the entrance surface M2 of the focusing assembly 2, so that the anti-shake lens group 1b and the focusing assembly 2 have a large inclination angle, the optical quality of the camera module 100 decreases greatly, the imaging quality is low, and the focus offset is large, so that the modulation transfer function of the camera module 100 as a whole decreases greatly, affecting the imaging quality.

[0186] In the embodiment, the second axis R2 can be parallel to the light-out axis T2, that is, the second axis R2 can be perpendicular to the exit surface 103 of the anti-shake lens group 1b and the incident surface M2 of the focusing assembly 2. In this way, when the anti-shake lens group 1b rotates around the second axis R2, the exit surface M1 of the anti-shake assembly 1 can always remain parallel to the light-out axis T2 and perpendicular to the incident surface M2 of the focusing assembly 2, thereby effectively reducing the inclination angle between the anti-shake lens group 1b and the focusing assembly 2, improving the anti-shake precision of the camera module 100, and reducing the optical quality degradation and the focal point deviation of the camera module 100, which is conducive to reducing the influence of the focal point deviation on the modulation transfer function, thereby improving the imaging quality of the camera module 100.

[0187] In addition, the distance between the second axis R2 and the light-out axis T2 can be less than or equal to 3 mm, so that the second axis R2 can be arranged close to the light-out axis T2, thereby better reducing the influence of the focal point deviation on the modulation transfer function and improving the imaging quality of the camera module 100.

[0188] It can be understood from FIGS. 2, 7a and 8b that, compared with a camera module in which a reflecting prism is additionally arranged between a focusing assembly and an image sensor and the optical anti-shake is realized by controlling the displacement of the image sensor, the volume of the camera module is large. In the embodiment, the camera module 100 realizes the optical image anti-shake of the entire camera module 100 by driving the anti-shake lens group 1b to rotate around the first axis R1 and / or the second axis R2 by the anti-shake motor 1a, thereby eliminating the need to additionally arrange a prism between the focusing assembly 2 and the image sensor 3, reducing the volume of the camera module, and being conducive to realizing the miniaturization of the camera module 100.

[0189] Secondly, in the embodiment, the first axis R1 is perpendicular to the light-in axis T1 and the light-out axis T2 (in the embodiment, that is, parallel to the Y-axis direction and perpendicular to the plane in which the light-in axis T1 and the light-out axis T2 are located), and is located on the side of the reflecting surface 102 of the anti-shake lens group 1b away from the incident surface 101 and the exit surface 103. The second axis R2 is parallel to the light-out axis T2. In this way, whether the anti-shake lens group 1b rotates around the first axis R1 or the second axis R2, the focal point deviation is small, and the exit surface M1 of the anti-shake assembly 1 can always remain parallel to the incident surface M2 of the focusing assembly 2, thereby effectively improving the anti-shake precision of the camera module 100, reducing the influence of the focal point deviation and the inclination angle on the modulation transfer function of the camera module 100 as a whole, and improving the imaging quality of the camera module 100.

[0190] In other words, the camera module 100 in the embodiment controls the anti-shake lens group 1b to rotate around the first axis R1 and / or the second axis R2 for anti-shake, the first axis R1 is parallel to the Y-axis direction, the second axis R2 is parallel to the X-axis direction, and the first axis R1 is located on the side of the reflecting surface 102 away from the incident surface 101 and the exit surface 103, so that the camera module 100 has a smaller focal point shift amount when performing optical image stabilization, thereby having higher anti-shake precision and better imaging quality.

[0191] The structure of the electronic device 1000, the structure of the camera module 100, and the anti-shake principle of the anti-shake assembly 1 of the camera module 100 are specifically introduced above, and the specific structure of the anti-shake motor 1a in the anti-shake assembly 1 in various embodiments will be specifically introduced below in combination with the related drawings.

[0231] Exemplarily, the first sub magnetic member 541 can include a first magnet 5411, a second magnet 5412 and a third magnet 5413. The first magnet 5411, the second magnet 5412 and the third magnet 5413 can all be single-pole magnetized magnets. The first magnet 5411, the second magnet 5412 and the third magnet 5413 can be arranged in sequence along the first direction Z.

The polarization direction of the second magnet 5412 can be perpendicular to the polarization direction of the first magnet 5411. It should be understood that the polarization direction can be the direction in which the N pole of a magnet points to the S pole. For example, the part of the first magnet 5411 close to the mounting slope 511a can be the N pole, and the part away from the mounting slope 511a can be the S pole. The part of the second magnet 5412 close to the first magnet 5411 can be the N pole, and the part close to the third magnet 5413 can be the S pole. The part of the third magnet 5413 close to the mounting slope 511a can be the S pole, and the part away from the mounting slope 511a can be the N pole. The arrangement of the second sub magnetic member 542 is substantially the same as that of the first sub magnetic member 541, which will not be described here. Exemplarily, the first group of magnetic members 53 can also include three magnets, and the arrangement of the three magnets can be substantially the same as that of the first sub magnetic member 541, which will not be described here. Among them, the three magnets of the first group of magnetic members 53 can be arranged in sequence along the second direction X.

[0232] In some embodiments, the first sub-magnetic piece 541 can further include only the first magnet 5411 and the second magnet 5412. The first magnet 5411 and the second magnet 5412 can be arranged along the first direction Z, and the polarization directions of the two can be opposite. In other embodiments, the first sub-magnetic piece 541 can further include only the first magnet 5411. The first magnet 5411 can be a bipolar magnet, i.e., the first magnet 5411 can include two N poles and two S poles at the same time. The two N poles and the two S poles can collectively form a magnetic field.

[0233] Referring again to FIGS. 24 and 25, the first plurality of balls 551 in the first plurality of support pieces can be arranged in the first sliding groove 5142 of the first connecting portion 514. The first sliding groove 5142 can be a "V"-shaped groove, i.e., the cross-sectional shape of the first sliding groove 5142 can be a "V"-shaped. At this time, the first plurality of balls 551 and the first sliding groove 5142 can be in a tight fit.

[0234] For example, the diameters of the first plurality of balls 551 at both ends of the first sliding groove 5142 in the extension direction can be slightly larger than the diameters of the remaining first plurality of balls 551. In this way, the smaller first plurality of balls 551 can increase the span between the first plurality of balls 551 at both ends of the first sliding groove 5142, and also avoid the first plurality of balls 551 from being stuck when sliding in the first sliding groove 5142.

[0235] For example, the second plurality of balls 552 in the second plurality of support pieces can be arranged in the second sliding groove 5152 of the second connecting portion 515. The second sliding groove 5152 can be a "U"-shaped groove, i.e., the cross-sectional shape of the second sliding groove 5152 can be a "U"-shaped. At this time, the second plurality of balls 552 and the second sliding groove 5152 can be in a loose fit. For example, the sizes of the second plurality of balls 552 at both ends of the second sliding groove 5152 can be slightly larger than the sizes of the remaining second plurality of balls 552 in the first sliding groove 5142.

[0236] In some embodiments, the first sliding groove 5142 can also be a "U"-shaped groove, and the second sliding groove 5152 can also be a "V"-shaped groove. Alternatively, the first sliding groove 5142 and the second sliding groove 5152 can both be "V"-shaped grooves. In other words, at least one of the first sliding groove 5142 and the second sliding groove 5152 is a "V"-shaped groove.

[0237] Referring again to FIGS. 24 and 25, and in combination with FIG. 21, the mover 50 can further include a third group of magnetic pieces 57. The third group of magnetic pieces 57 can be fixed to the side of the extension protrusion 516 of the carrier 51 facing away from the installation inclined surface 511a. In some embodiments, the extension protrusion 516 can further be provided with a groove for accommodating the third group of magnetic pieces 57.

[0238] Exemplarily, the mover 50 can further include a fourth set of magnetic pieces 58. The fourth set of magnetic pieces 58 can be fixed in the fourth mounting slots 5114 of the carrier 51. In the present embodiment, the fourth set of magnetic pieces 58 can include two magnets. The two magnets can be fixed in the two fourth mounting slots 5114, respectively.

[0239] FIG. 26 is a schematic structural view of the guide bracket 52 of the mover 50 shown in FIG. 21 in some embodiments. FIG. 27 is a schematic structural view of the assembly of the guide bracket 52 and the second set of support pieces 56 shown in FIG. 26 in another perspective view.

[0240] As shown in FIGS. 26 and 27, the guide bracket 52 can include a first portion 521, a second portion 522, and a third portion 523. The first portion 521 and the second portion 522 can be oppositely and spacedly arranged. The arrangement direction of the first portion 521 and the second portion 522 can be parallel to the third direction Y. The first portion 521 and the second portion 522 can be located on the same side of the third portion 523 and are fixedly connected to the third portion 523. At this time, the guide bracket 52 can be substantially in the shape of a “concave” character. It should be noted that the first portion 521, the second portion 522, and the third portion 523 are schematically divided by the dashed lines in FIGS. 26 and 27.

[0241] Exemplarily, the side of the first portion 521 away from the third portion 523 can be provided with a first notch 521a. The bottom surface of the first notch 521a can be provided with a first guide slot 5211. The first guide slot 5211 can be communicated with the first notch 521a. The opening of the first guide slot 5211 can be away from the third portion 523. The side of the second portion 522 away from the third portion 523 can be provided with a second notch 522a. The bottom surface of the second notch 522a can be provided with a second guide slot 5221. The second guide slot 5221 can be communicated with the second notch 522a.

[0242] Exemplarily, the third portion 523 can be provided with at least three guide grooves. The openings of the plurality of guide grooves can be identical, and can be formed on the surface of the third portion 523 facing away from the first portion 521 and the second portion 522. In the present embodiment, the number of guide grooves of the third portion 523 can be four, for example, can include a third guide groove 5231, a fourth guide groove 5232, a fifth guide groove 5233, and a sixth guide groove 5234. The third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 can all be circular arc grooves. The centers of curvature of the above-mentioned four guide grooves can coincide. Exemplarily, a plurality of second support members (in the present embodiment, namely a plurality of third rolling balls 561) can be provided in one-to-one correspondence in the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234.

FIG. 28b is a schematic diagram of the cross-sectional structure of the rotor 50 shown in FIG. 20 along D3-D3 in an embodiment. FIG. 29 is a schematic diagram of the cross-sectional structure of the rotor 50 shown in FIG. 20 along D1-D1 in an embodiment.

[0245] As shown in FIGS. 28a-29, the first connecting portion 514 of the carrier 51 can be mounted in the first notch 521a of the first portion 521 of the guide bracket 52. The first connecting portion 514 can be rotationally connected to the first portion 521 through a plurality of first rolling balls 551. The opening of the first sliding groove 5142 of the first connecting portion 514 can be arranged opposite the opening of the first guide groove 5211 of the first portion 521. A part of each first rolling ball 551 can be located in the first sliding groove 5142 of the first connecting portion 514, and a part can be located in the first guide groove 5211 of the first portion 521. The first portion 521 of the guide bracket 52 can semi-enclose the first connecting portion 514 of the carrier 51. In this way, the structure of the first portion 521 and the first connecting portion 514 is relatively compact, which is conducive to realizing the miniaturization of the anti-shake motor 1a.

[0246] Exemplarily, the center of the circle in which the centers of the plurality of first balls 551 are located can be the first rotation center O1. The first connecting portion 514 of the carrier 51 can rotate relative to the first portion 521 of the guide bracket 52 about the first rotation center O1. It should be understood that when the sizes of the plurality of first balls 551 are not completely the same (for example, the sizes of the first balls 551 located at both ends of the first sliding groove 5142 are greater than the sizes of the remaining first balls 551), the center of the circle in which the centers of the plurality of first balls 551 with larger sizes are located can be taken as the first rotation center O1. In some embodiments, the center of the circle in which the fitting curve of the groove wall of the first sliding groove 5142 is located can also be taken as the first rotation center O1.

[0247] Exemplarily, the second connecting portion 515 of the carrier 51 can be installed in the second notch 522a of the second portion 522 of the guide bracket 52. The second connecting portion 515 can be rotationally connected to the second portion 522 through the plurality of second balls 552. The opening of the second sliding groove 5152 of the second connecting portion 515 can be arranged opposite to the opening of the second guide groove 5221 of the second portion 522. A part of each second ball 552 can be located in the second sliding groove 5152 of the second connecting portion 515, and a part can be located in the second guide groove 5221 of the second portion 522. The second portion 522 of the guide bracket 52 can semi-enclose the second connecting portion 515 of the carrier 51. In this way, the structure of the second portion 522 and the second connecting portion 515 is relatively compact, which is beneficial to realize the miniaturization of the anti-shake motor 1a.

[0248] Exemplarily, the center of the circle in which the centers of the plurality of second balls 552 are located constitutes the second rotation center O2. The second connecting portion 515 of the carrier 51 can rotate relative to the second portion 522 of the guide bracket 52 about the second rotation center O2.

[0249] Exemplarily, the straight line in which the first rotation center O1 and the second rotation center O2 are located can coincide with the first axis R1. The first axis R1 can be parallel to the third direction Y. The carrier 51 can rotate relative to the guide bracket 52 about the first axis R1. Exemplarily, the first axis R1 can pass through the carrier 51, for example, the first axis R1 can pass through the first connecting portion 514 and the second connecting portion 515. In some embodiments, the first axis R1 can also not pass through the first connecting portion 514 and the second connecting portion 515. The first axis R1 can also be located on the side of the first connecting portion 514 and the second connecting portion 515 away from the installation inclined surface 511a.

[0250] Exemplarily, one of the first guide slot 5211 and the second guide slot 5221 can be a "V" shaped slot. In this way, on the one hand, the relative position between the actual first rotation center O1 and the theoretical first rotation center O1 can be automatically corrected, so that the movement of the carrier 51 relative to the guide bracket 52 can be smoother; on the other hand, it can also avoid the situation that the first guide slot 5211 and the second guide slot 5221 are both "V" shaped slots, which may cause the carrier 51 to be stuck when rotating relative to the guide bracket 52. In other embodiments, one of the first sliding slot 5142 and the second sliding slot 5152 of the carrier 51 can also be a "V" shaped slot. At least one of the first guide slot and the second guide slot 5221 of the guide bracket 52 is a "V" shaped slot.

[0251] As shown in FIGS. 28a-29, the support portion 511 of the carrier 51 can be arranged opposite and spaced apart from the third portion 523 of the guide bracket 52.

The mounting slope 511a of the carrier 51 can be towards the light inlet hole 20a and the light outlet hole 20b. The side of the mounting slope 511a towards the light inlet hole 20a and the light outlet hole 20b can be the mounting side 51b. The first axis R1 can be located at the side of the mounting slope 511a of the carrier 51 away from the mounting side 51b, i.e., the first axis R1 can be located at the side of the mounting slope 511a away from the light inlet hole 20a and the light outlet hole 20b. The mounting space 51a can be located at the mounting side 51b of the mounting slope 511a.

[0254] Exemplarily, the first position sensor 331 can be located at the side of the first side wall 512 of the carrier 51 away from the second side wall 513. The first position sensor 331 can overlap with the first sub-magnetic member 541 along at least part of the projection of the third direction Y on the plane where the first sub-magnetic member 541 is located. The arrangement direction of the first position sensor 331 and the first sub-magnetic member 541 can be parallel to the third direction Y. The first position sensor 331 can be used to detect the magnetic field change of the first sub-magnetic member 541. In some embodiments, there can be part of the first side plate 12 of the base 10 between the first position sensor 331 and the first sub-magnetic member 541. The material of the base 10 can be a non-metal material. The first position sensor 331 can still detect the magnetic field change of the first sub-magnetic member 541.

[0255] Exemplarily, the second position sensor 332 can be located on the side of the second side wall 513 of the carrier 51 opposite to the first side wall 512.

The arrangement direction of the second position sensor 332 and the second sub-magnetic piece 542 can be parallel to the third direction Y. The second position sensor 332 can be used to detect the magnetic field change of the second sub-magnetic piece 542.

[0256] Exemplarily, the avoiding hole 5235 of the third portion 523 of the guide bracket 52 can be arranged opposite to the fourth hole 141 of the third side plate 14 of the base 10 and in communication with each other. At this time, the extension protrusion 516 of the carrier 51 can be arranged opposite to and spaced apart from the third side plate 14 of the base 10. The third group of magnetic pieces 57 fixed to the extension protrusion 516 can be exposed opposite to the avoiding hole 5235 of the third portion 523 of the guide bracket 52. The third group of magnetic pieces 57 can be arranged opposite to and spaced apart from the first position sensor 331.

[0257] Exemplarily, the arrangement direction of the third magnetic attraction piece 43 and the fourth group of magnetic pieces 58 can be parallel to the second direction X. The projection of the third magnetic attraction piece 43 on the first face 5111 of the support portion 511 of the carrier 51 can cover at least part of the fourth group of magnetic pieces 58. In this way, the fourth group of magnetic pieces 58 can cooperate with the third magnetic attraction piece 43 to generate a magnetic attraction force along the second direction X, thereby providing a pre-pressure along the second direction X for the carrier 51, so that the carrier 51 can press the guide bracket 52 under the action between the fourth group of magnetic pieces 58 and the third magnetic attraction piece 43, so that the plurality of first support pieces (in this embodiment, the plurality of first rolling balls 551 and the plurality of second rolling balls 552) can maintain contact with the carrier 51 and the guide bracket 52, and at the same time, the plurality of second support pieces can maintain contact with the guide bracket 52 and the base 10.

[0260] As shown in FIGS. 32-34, the third portion 523 of the guide bracket 52 can be located between the third side plate 14 of the base 10 and the carrier 51. The guide bracket 52 can be rotatably connected to the base 10 by the plurality of third rolling balls 561. The openings of the first sliding groove 142, the second sliding groove 143, the third sliding groove 144, and the fourth sliding groove 145 (see FIG. 12) of the third side plate 14 of the base 10 can be correspondingly arranged with the openings of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 (see FIG. 27) of the guide bracket 52, and form a plurality of rolling ball grooves. The four third rolling balls 561 can be correspondingly located in the sliding grooves and the guide grooves. At this time, the third portion 523 of the guide bracket 52 can be rotatably connected to the third side plate 14 of the base 10 by the plurality of third rolling balls 561.

[0261] Exemplarily, the centers of the plurality of third rolling balls 561 can be located on the same plane. The center of the circle in which the centers of the plurality of third rolling balls 561 are located is the third rotation center O3, i.e., the center of the second group of support members 56. The second axis R2 can pass through the plane in which the centers of the plurality of third rolling balls 561 are located perpendicularly. The second axis R2 can also pass through the third rotation center O3. At this time, the guide bracket 52 can rotate relative to the base 10 about the second axis R2. The third rotation center O3 can be located on the side of the mounting slope 511a of the carrier 51 away from the light inlet hole 20a and the light outlet hole 20b, i.e., on the side of the mounting slope 511a away from the mounting side 51b. The second axis R2 can pass through the mounting slope 511a and be parallel to the second direction X.

[0262] Exemplarily, two of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 can be “V”-shaped grooves. In this way, on the one hand, two of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 being “V”-shaped grooves can automatically correct the relative positions of the actual third rotation center O3 and the theoretical third rotation center O3, so that the movement of the guide bracket 52 relative to the base 10 can be smoother; on the other hand, it can also avoid the situation that all of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 are “V”-shaped grooves or three of them are “V”-shaped grooves, which can cause the guide bracket 52 to be stuck when rotating relative to the base 10. In other embodiments, two of the first sliding groove 142, the second sliding groove 143, the third sliding groove 144, and the fourth sliding groove 145 of the carrier 51 can also be “V”-shaped grooves. At least two of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 of the guide bracket 52 are “V”-shaped grooves.

[0263] FIG. 35 is a structural schematic diagram of the anti-shake assembly 1 shown in FIG. 3 from another perspective. FIG. 36a is a cross-sectional structural schematic diagram of the anti-shake assembly 1 shown in FIG. 3 along B1-B1 in an embodiment. FIG. 36b is a cross-sectional structural schematic diagram of the anti-shake assembly 1 shown in FIG. 3 along B2-B2 in an embodiment. In the drawings, the anti-shake assembly 1 shown in FIG. 35 hides part of the housing 20.

[0264] As shown in FIGS. 35-36b, the anti-shake lens group 1b can be mounted on the carrier 51. The anti-shake lens group 1b can have negative optical power. The anti-shake lens group 1b can include the optical folding element 104, the first lens 105, and the second lens 106. The optical folding element 104 can be fixedly connected to the carrier 51 by adhesion or the like. The first lens 105 can have positive optical power. The first lens 105 can be located on the side of the carrier 51 close to the light inlet hole 20a. The first lens 105 can be fixedly connected to the top of the carrier 51 by adhesion or the like. The second lens 106 can be located on the side of the carrier 51 close to the light outlet hole 20b. The second lens 106 can have negative optical power. The second lens 106 can be fixedly connected to the end of the carrier 51 close to the light outlet hole 20b by clamping or the like. The system focal point of the anti-shake lens group 1b can be located on the side of the mounting slope 511a of the carrier 51 away from the mounting side 51b. At this time, the optical folding element 104, the first lens 105, and the second lens 106 can move together with the carrier 51, that is, the anti-shake lens group 1b can move together with the carrier 51.

[0265] Exemplarily, the optical folding element 104 can be a reflective triangular prism. It should be noted that when the anti-shake lens group 1b is mounted on the carrier 51, the reflective surface of the anti-shake lens group 1b is opposite to the mounting slope 511a, the reflective surface of the anti-shake lens group 1b can be in contact with the mounting slope 511a, or there can be a small gap. The small gap can be formed by an air gap or the thickness of a fixing member (such as a glue layer or the like). At this time, the small gap between the reflective surface and the mounting slope 511a can be ignored, and the reflective surface and the mounting slope 511a can be considered to be coincident. That is, the first axis R1 can be located on the side of the reflective surface away from the light inlet hole 20a and the light outlet hole 20b.

[0266] Exemplarily, the light-incoming axis T1 of the anti-shake lens group 1b can pass through the light-incoming hole 20a and the mounting slope 511a. The light-incoming axis T1 can be parallel to the first direction Z (in this embodiment, also the first direction Z). The light-outgoing axis T2 of the anti-shake lens group 1b can pass through the mounting slope 511a and the light-outgoing hole 20b. The light-outgoing axis T2 can be parallel to the second direction X (in this embodiment, also the second direction X). The first axis R1 can be perpendicular to the plane in which the light-incoming axis T1 and the light-outgoing axis T2 lie. The second axis R2 can coincide with the light-outgoing axis T2. Exemplarily, the first axis R1 and the second axis R2 can intersect at a fifth intersection point G5. The first axis R1 and the second axis R2 can be perpendicular to each other. The fifth intersection point G5 can be located on the side of the mounting slope 511a facing away from the mounting side 51b. At this time, the fifth intersection point G5 can coincide with the second intersection point G2 (please refer to FIG. 7a). In other embodiments, the first axis R1 can also not intersect with the second axis R2. The present application does not limit this.

[0267] FIG. 37 is a circuit schematic diagram of the first position sensor 331 and the second position sensor 332 in the anti-shake assembly 1 shown in FIG. 3.

[0268] As shown in FIGS. 36a-37, the anti-shake motor 1a can further include a first driving mechanism and a second driving mechanism. The first driving mechanism can be used to drive the carrier 51 to rotate relative to the guide support 52 about the first axis R1. The second driving mechanism can be used to drive the carrier 51 and the guide support 52 together to rotate relative to the base 10 about the second axis R2. The anti-shake motor 1a can further include a first detection assembly 61 and a second detection assembly 62. The first detection assembly 61 can be used to detect the angle of rotation of the carrier 51 about the first axis R1. The second detection assembly 62 can be used to detect the angle of rotation of the carrier 51 about the second axis R2. The first detection assembly 61 and the second detection assembly 62 can each include at least one set of position sensors and magnetic pieces cooperating with the position sensors. Exemplarily, the first detection assembly 61 can include a first position sensor 331, a second position sensor 332, a first magnetic piece 611, and a second magnetic piece 612. The first position sensor 331 can be used to detect the magnetic field change of the first magnetic piece 611. The second position sensor 332 can be used to detect the magnetic field change of the second magnetic piece 612. The second detection assembly 62 can include a third position sensor 333 and a third magnetic piece 621. The third position sensor 333 can be used to detect the magnetic field change of the third magnetic piece 621. The first magnetic piece 611, the second magnetic piece 612, and the third magnetic piece 621 can each be fixed to the carrier 51.

[0269] Exemplarily, the first driving coil 32a can be located on the side of the carrier 51 opposite to the light inlet hole 20a. The winding plane of the first driving coil 32a can be perpendicular to the light inlet axis T1. When the first driving coil 32a is applied with a signal, the first set of magnetic pieces 53 can cooperate with the first driving coil 32a to generate a driving force parallel to the second direction X, so as to drive the carrier 51 to rotate around the first axis R1 relative to the guide support 52, that is, the carrier 51 rotates around the first axis R1 relative to the stator. At this time, the anti-shake lens group 1b can rotate around the first axis R1 relative to the base 10 under the action of the carrier 51. That is, the anti-shake lens group 1b can rotate around the first axis R1 relative to the stator under the action of the mover 50, so as to realize anti-shake.

[0270] The first set of magnetic pieces 53 and the first driving coil 32a can jointly constitute a first driving mechanism of the anti-shake motor 1a. The third position sensor 333 can cooperate with the third set of magnetic pieces 57 to detect the magnetic field change of the third set of magnetic pieces 57 under different angles of rotation of the carrier 51 around the first axis R1, so as to detect the angle of rotation of the carrier 51 around the first axis R1. At this time, the third position sensor 333 and the third set of magnetic pieces 57 can jointly constitute a second detection assembly 62 of the anti-shake motor 1a. The third set of magnetic pieces 57 can constitute a third magnetic piece 621 of the second detection assembly 62.

[0271] Exemplarily, when the second driving coil 32b is applied with a signal, the first sub-magnetic piece 541 of the second set of magnetic pieces 54 can cooperate with the first coil 321 of the second driving coil 32b to generate a first driving force along the first direction Z. The second sub-magnetic piece 542 of the second set of magnetic pieces 54 can cooperate with the second coil 322 of the second driving coil 32b to generate a second driving force along the first direction Z. The direction of the first driving force is opposite to the direction of the second driving force, so as to drive the carrier 51 to rotate around the second axis R2 relative to the base 10 together with the guide support 52, that is, the carrier 51 can rotate around the second axis R2 relative to the stator together with the guide support 52. At this time, the anti-shake lens group 1b can rotate around the second axis R2 relative to the base 10 under the action of the carrier 51. That is, the anti-shake lens group 1b can rotate around the second axis R2 relative to the stator under the action of the mover 50, so as to realize anti-shake.

[0272] The second set of magnetic components 54 and the second drive coil 32b together constitute the second drive mechanism of the anti-shake motor 1a. The first position sensor 331 cooperates with the first sub-magnetic component 541, and the second position sensor 332 cooperates with the second sub-magnetic component 542 to jointly detect the magnetic field changes when the carrier 51 rotates around the second axis R2 at different angles, thereby detecting the angle of rotation of the carrier 51 around the second axis R2. In this case, the first position sensor 331, the second position sensor 332, and the second set of magnetic components 54 together constitute the first detection component 61 of the anti-shake motor 1a. The first sub-magnetic component 541 of the second set of magnetic components 54 can constitute the first magnetic component 611 of the first detection component 61. The second sub-magnetic component 542 can constitute the second magnetic component 612 of the first detection component 61.

[0273] For example, the input terminal of the first position sensor 331 can be connected in parallel with the input terminal of the second position sensor 332. The output terminal of the first position sensor 331 can be connected in parallel with the output terminal of the second position sensor 332. In this way, the first position sensor 331 and the second position sensor 332 can reduce the inductive crosstalk problem caused by the first set of magnetic components 53 and the second set of magnetic components 54 being mounted on the carrier 51 through differential operation, and cancel the influence of the change in the magnetic field of the second set of magnetic components 54 caused by the rotation of the carrier 51 around the first axis R1 on the first position sensor 331 and the second position sensor 332, thereby improving the control accuracy of the anti-shake motor 1a and improving the anti-shake accuracy.

[0274] The first position sensor 331 may include a first input terminal 3311, a first positive output terminal 3312, and a first negative output terminal 3313. The second position sensor 332 may include a second input terminal 3321, a second positive output terminal 3322, and a second negative output terminal 3323. The first input terminal 3311 may be connected in parallel with the second input terminal 3321. When the magnetic field direction of the first sub-magnetic element 541 is symmetrically arranged with the magnetic field direction of the second sub-magnetic element 542, the first positive output terminal 3312 may be connected in parallel with the second negative output terminal 3323, and the first negative output terminal 3313 may be connected in parallel with the second positive output terminal 3322. When the magnetic field direction of the first sub-magnetic element 541 is the same as the magnetic field direction of the second sub-magnetic element 542, the first positive output terminal 3312 may be connected in parallel with the second positive output terminal 3322, and the first negative output terminal 3313 may be connected in parallel with the second negative output terminal 3323.

[0275] It is understandable that, compared to some image stabilization motors where the mover drives the image stabilization lens group to rotate relative to the stator around a first axis and around a second axis to achieve optical image stabilization, the first axis is parallel to a third direction. The first axis is located on the mounting slope of the mover. The second axis is parallel to the first direction. This results in a larger focus shift when the image stabilization motor drives the image stabilization lens group to rotate around the second axis for optical image stabilization, leading to a significant decrease in the modulation transfer function of the entire camera module, lower stabilization accuracy, and affecting image quality. In this embodiment, the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate relative to the stator around a second axis R2, which is parallel to the second direction X. Thus, when the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate around the second axis R2, the exit surface of the image stabilization component 1 can always remain perpendicular to the light output axis T2. This effectively reduces the tilt angle between the image stabilization component 1 and the focusing component 2, reduces the focus offset, and helps improve the image stabilization accuracy of the entire camera module 100. The camera module 100 has higher optical quality, which is beneficial to improving image quality. Meanwhile, in this embodiment, the first axis R1 of the image stabilization motor 1a is located on the side of the mounting inclined surface 511a facing away from the light inlet aperture 20a and the light outlet aperture 20b, that is, the side of the mounting inclined surface 511a facing away from the mounting side 51b. The first axis R1 can be parallel to the third direction Y. When the image stabilization lens group 1b has negative optical power, the system focus of the image stabilization lens group 1b can be located on the side of the mounting inclined surface 511a facing away from the mounting side 51b. That is, the system focus of the image stabilization lens group 1b and the first axis R1 can both be located on the side of the mounting slope 511a facing away from the mounting side 51b. In this way, the distance between the first axis R1 and the system focus of the image stabilization lens group 1b is relatively small. When the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate around the first axis R1, the focus offset is small. This can effectively reduce the impact of focus offset on the modulation transfer function, which is beneficial to improving the image stabilization accuracy of the entire camera module 100 and improving image quality.

[0276] In other words, the image stabilization motor 1a in this embodiment can effectively improve the overall image stabilization accuracy of the image stabilization motor 1a and reduce the impact on the modulation transfer function by setting the first axis R1 to be parallel to the third direction Y and the second axis R2 to be parallel to the second direction X, and the first axis R1 is located on the side of the mounting slope 511a of the mover 50 facing away from the mounting side 51b. This is beneficial to improving the imaging quality of the camera module 100.

[0277] Secondly, in this embodiment, the first axis R1 can pass through the carrier 51. In this way, the first axis R1 can be relatively close to the center of gravity of the carrier 51 and the image stabilization lens group 1b as a whole. On the one hand, this can effectively enhance the anti-interference ability of the carrier 51 when rotating around the first axis R1 for image stabilization; on the other hand, it can also reduce the power consumption of the image stabilization motor 1a, which is beneficial to extending the battery life of the electronic device 1000 and improving the user experience.

[0278] In addition, in this embodiment, the multiple sets of magnetic components (i.e., the first set of magnetic components 53 and the second set of magnetic components 54 in this embodiment) used to form the drive mechanism in the anti-shake motor 1a are all mounted on the carrier 51, thereby achieving integrated transmission and improving the smoothness of the anti-shake motor 1a when performing anti-shake operation.

[0279] Furthermore, the anti-shake motor 1a in this embodiment also includes a first magnetic attractor 41 and a second magnetic attractor 42. The first magnetic attractor 41 and the first sub-magnetic element 541 can generate an interaction force. The second magnetic attractor 42 and the second sub-magnetic element 542 can also generate an interaction force. Thus, when the carrier 51 rotates relative to the base 10 around the first axis R1, the first magnetic attractor 41 and the first sub-magnetic element 541 can generate a magnetic attraction restoring force along the first direction Z, and the second magnetic attractor 42 and the second sub-magnetic element 542 can generate a magnetic attraction restoring force along the first direction Z. Since the two magnetic attraction restoring forces are in the same direction, a resistance torque around the first axis R1 can be generated, which is beneficial for achieving rapid closed-loop control when the carrier 51 rotates around the first axis R1. When the carrier 51 rotates relative to the base 10 around the second axis R2, a magnetic attraction restoring force along the first direction Z can be generated between the first magnetic attraction member 41 and the first sub-magnetic member 541, and a magnetic attraction restoring force along the first direction Z can be generated between the second magnetic attraction member 42 and the second sub-magnetic member 542. The two magnetic attraction restoring forces are in opposite directions, thereby generating a resistance torque on the second axis R2, which is beneficial to achieving rapid closed-loop control when the carrier 51 rotates around the second axis R2.

[0280] Furthermore, conventional image stabilization motors typically place the third position sensor on the side of the carrier facing away from the light-emitting aperture, opposite to the first set of magnetic components. The third position sensor detects changes in the magnetic field of the first set of magnetic components to determine the angle of rotation of the carrier around the first axis. However, this arrangement results in a large distance between the third position sensor and the second axis. When the carrier rotates around the second axis, the displacement of the third position sensor 333 is significant, leading to greater interference from the magnetic field during the carrier's rotation and reducing the accuracy of the third position sensor in detecting the angle of rotation around the first axis. In this embodiment, the image stabilization motor 1a also includes a third magnetic component 621 (also known as the third set of magnetic components 57 in this embodiment). The third set of magnetic components 57 can be fixed to the side of the carrier 51 facing away from the light-emitting aperture 20b. The third position sensor 333 is fixed to the base 10. The projection of the third position sensor 333 onto the plane of the third set of magnetic components 57 can overlap with the third set of magnetic components 57. In this way, the distance between the third position sensor 333 and the second axis R2 is relatively close, which can reduce the displacement generated by the third position sensor 333 when the carrier 51 rotates around the second axis R2, effectively improving the detection accuracy of the third position sensor 333 and improving the anti-shake accuracy of the anti-shake motor 1a.

[0281] In some embodiments, the first set of magnetic components 53 and the first drive coil 32a can also together constitute the second drive mechanism of the anti-shake motor 1a. The second set of magnetic components 54 and the second drive coil 32b can also together constitute the first drive mechanism of the anti-shake motor 1a.

[0282] In some embodiments, referring to FIG32, the first position sensor 331 may be disposed closer to the guide bracket 52 than the first coil 321. The second position sensor 332 may be disposed closer to the guide bracket 52 than the second coil 322. In this way, both the first position sensor 331 and the second position sensor 332 can be disposed close to the first axis R1, thereby reducing the distance between the first position sensor 331 and the first axis R1 and reducing the distance between the second position sensor 332 and the first axis R1. This can effectively reduce the displacement of the first position sensor 331 and the second position sensor 332 when the carrier 51 rotates around the first axis R1, effectively improving the detection accuracy of the first position sensor 331 and the second position sensor 332, and improving the anti-shake accuracy of the anti-shake motor 1a.

[0283] Figure 38 is a schematic cross-sectional view of the mover 50 shown in Figure 28a in another embodiment. Figure 39 is a schematic cross-sectional view of the mover 50 shown in Figure 28a in yet another embodiment.

[0284] In some embodiments, as shown in FIG38, the first portion 521 of the guide bracket 52 may not include the first notch. The first connecting portion 514 of the carrier 51 may also have a third notch 5143 on the side near the first portion 521 of the guide bracket 52. The opening of the first sliding groove 5142 may be formed on the bottom surface of the third notch 5143. The first sliding groove 5142 may communicate with the third notch 5143. The first portion 521 may be installed within the third notch 5143 of the first connecting portion 514. The first portion 521 may be rotatably connected to the first connecting portion 514 via a plurality of first ball bearings 551. In this case, the first connecting portion 514 may partially surround the first portion 521.

[0285] In some embodiments, as shown in FIG39, the number of first ball bearings 551 may be one. The first connecting portion 514 of the carrier 51 can be rotatably connected to the first part 521 of the guide bracket 52 via one first ball bearing 551. A portion of the first ball bearing 551 may be located within the first sliding groove 5142 of the first connecting portion 514. A portion of the first ball bearing 551 may be located within the first guide groove 5211 of the first part 521. The first ball bearing 551 can movably connect the first part 521 and the first connecting portion 514. In this case, the center of the first ball bearing 551 can constitute the first rotation center O1. In other embodiments, the first ball bearing 551 may also be fixedly connected to the first connecting portion 514 and movably connected to the first part 521. In this case, the contact point between the first ball bearing 551 and the first part 521 can constitute the first rotation center O1. Alternatively, the first ball bearing 551 may also be fixedly connected to the first part 521 and movably connected to the first connecting portion 514. At this time, the contact point between the first ball 551 and the first connecting part 514 can form the first rotation center O1.

[0286] In other embodiments, a portion of the first portion 521 of the guide bracket 52 may further protrude in the direction toward the first connecting portion 514, forming a first protrusion (not shown). The surface of the first protrusion toward the first connecting portion 514 may be an arcuate surface. The first connecting portion 514 can slidably connect to the arcuate surface of the first protrusion. In this case, the first protrusion may constitute a first support member. That is, the first support member may also be constituted by a portion of the guide bracket 52. In some other embodiments, the first support member may also be constituted by a portion of the carrier 51.

[0287] The following sections will introduce several settings for the anti-shake motor 1a, along with related attached diagrams.

[0288] The second embodiment: Figure 40 is a partial structural schematic diagram of the anti-shake motor 1a shown in Figure 10 in the second embodiment. Figure 41 is an exploded structural schematic diagram of the structure shown in Figure 39 in some embodiments. For ease of understanding, the housing 20 of the anti-shake motor 1a is hidden in Figure 40.

[0289] As shown in Figures 40 and 41, the structure of the anti-shake motor 1a in this embodiment is largely the same as that shown in Figure 10, and the identical parts will not be described again. The following describes some differences between the two embodiments. Exemplarily, the second drive coil 32b may include a first coil 321 and a second coil 322. The first coil 321 may be fixedly connected to the surface of the first extension plate 312 of the circuit board 31 facing the second extension plate 313. The second coil 322 may be fixedly connected to the surface of the second extension plate 313 facing the first extension plate 312. The arrangement direction of the first coil 321 and the second coil 322 may be parallel to the third direction Y. The first drive coil 32a may also include a third coil 323 and a fourth coil 324. The third coil 323 may be fixedly connected to the surface of the first extension plate 312 facing the second extension plate 313. The fourth coil 324 may be fixedly connected to the surface of the second extension plate 313 facing the first extension plate 312. The arrangement direction of the third coil 323 and the fourth coil 324 may be parallel to the third direction Y. The third coil 323 may be arranged side-by-side with the first coil 321. The third coil 323 and the first coil 321 can be arranged in a direction parallel to the second direction X. The fourth coil 324 can be arranged side by side with the second coil 322. The fourth coil 324 and the second coil 322 can be arranged in a direction parallel to the second direction X.

[0290] Figure 42 is an exploded structural diagram of the mover 50 shown in Figure 41 in some embodiments. Figure 43 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 40 cut along E1-E1. Figure 44 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 40 cut along E2-E2.

[0291] As shown in Figures 42 to 44, the anti-shake motor 1a may not include the first set of magnetic components. The second set of magnetic components 54 may include a first sub-magnetic component 541 and a second sub-magnetic component 542. The first sub-magnetic component 541 may be fixed to the first sidewall 512 of the carrier 51. The second sub-magnetic component 542 may be fixed to the second sidewall 513 of the carrier 51. The arrangement direction of the first sub-magnetic component 541, the mounting inclined surface 511a, and the second sub-magnetic component 542 may be parallel to a third direction Y. The polarization direction of the first sub-magnetic component 541 may be the same as or opposite to the polarization direction of the second sub-magnetic component 542. In this embodiment, the polarization direction of the first sub-magnetic component 541 may be opposite to the polarization direction of the second sub-magnetic component 542. The polarization direction of the first sub-magnetic component 541 may be parallel to a first direction Z.

[0292] Exemplarily, both the first coil 321 and the third coil 323 can be disposed opposite to the first sub-magnetic element 541. Both the second coil 322 and the fourth coil 324 can be disposed opposite to the second sub-magnetic element 542. When a signal is applied to the first driving coil 32a, the third coil 323 can cooperate with the first sub-magnetic element 541 to generate a third driving force along the first direction Z. The fourth coil 324 can cooperate with the second sub-magnetic element 542 to generate a fourth driving force along the first direction Z. The direction of the third driving force can be the same as the direction of the fourth driving force, thereby driving the carrier 51 to rotate relative to the guide bracket 52 about the first axis R1. At this time, the second set of magnetic elements 54 can together with the first driving coil 32a constitute a first driving mechanism. When a signal is applied to the second driving coil 32b, the second driving coil 32b can cooperate with the second set of magnetic elements 54 to drive the carrier 51 to rotate together with the guide bracket 52 relative to the base 10 about the second axis R2. At this time, the second set of magnetic elements 54 can also together with the second driving coil 32b constitute a second driving mechanism.

[0293] It is understood that in this embodiment, the first drive coil 32a may include a third coil 323 and a fourth coil 324, and the second drive coil 32b may include a first coil 321 and a second coil 322. The third coil 323 and the first coil 321 can both be arranged opposite to the first sub-magnetic element 541 of the second set of magnetic elements 54. The fourth coil 324 and the second coil 322 can both be arranged opposite to the second sub-magnetic element 542 of the second set of magnetic elements 54. The second set of magnetic elements 54 can cooperate with the first drive coil 32a to drive the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1. The second set of magnetic elements 54 can also cooperate with the second drive coil 32b to drive the carrier 51 and the guide bracket 52 to rotate together relative to the base 10 around the second axis R2. In this way, compared to some embodiments where the anti-shake motor requires two sets of magnetic elements to cooperate with two sets of drive coils respectively to drive the carrier to move around the first and second axes, resulting in more components and higher manufacturing costs, this method is more efficient. In this embodiment, the image stabilization motor 1a only requires one set of magnetic components (i.e., the second set of magnetic components 54 in this embodiment) to drive the carrier 51. The first drive coil 32a and the second drive coil 32b can share the same set of magnetic components, thereby driving the carrier 51 to rotate around the first axis R1 and around the second axis R2 respectively, effectively reducing the number of components in the image stabilization motor 1a. Simultaneously, the weight of the mover 50 of the image stabilization motor 1a can also be reduced. With the same total weight of the mover 50 and the image stabilization lens group 1b, the image stabilization motor 1a in this embodiment can generate greater thrust for image stabilization, achieving large-angle image stabilization. With the same image stabilization angle, the mover 50 in this embodiment can support the heavier image stabilization lens group 1b, which is beneficial for improving the optical quality of the entire camera module.

[0294] In some embodiments, the third coil 323 may be positioned further away from the first axis R1 than the first coil 321. The fourth coil 324 may be positioned further away from the first axis R1 than the second coil 322. This greater distance between the first drive coil 32a and the first axis R1 results in a larger rotational arm when the first drive coil 32a, in conjunction with the second set of magnetic components 54, drives the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1, which is beneficial for improving anti-shake efficiency.

[0295] Third embodiment: Figure 45 is a structural schematic diagram of the anti-shake motor 1a shown in Figure 10 in the third embodiment. Figure 46 is an exploded structural schematic diagram of the structure shown in Figure 45 in some embodiments. Figure 47 is an exploded structural schematic diagram of the mover 50 shown in Figure 46 in some embodiments.

[0296] As shown in Figures 45 to 47, the structure of the image stabilization motor 1a in this embodiment is largely the same as that shown in Figure 10, and the identical parts will not be described again. The following describes some differences between the two embodiments. Exemplarily, the first connecting portion 514 and the second connecting portion 515 of the carrier 51 of the image stabilization motor 1a can also be located on the side of the carrier 51 near the light-emitting hole 20b. Specifically, the first connecting portion 514 can be located on the side of the first sidewall 512 of the carrier 51 facing away from the second sidewall 513, and is fixedly connected to the end of the first surface 5111 of the first sidewall 512 away from the support portion 511. The second connecting portion 515 can be located on the side of the second sidewall 513 of the carrier 51 facing away from the first sidewall 512, and is fixedly connected to the end of the second sidewall 513 away from the first surface 5111 of the support portion 511. The arrangement direction of the first connecting portion 514 and the second connecting portion 515 can be parallel to a third direction Y.

[0297] For example, the guide bracket 52 may include a first portion 521, a second portion 522, and a third portion 523. The first portion 521 and the second portion 522 may be arranged opposite to each other and spaced apart. The shape of the first portion 521 and the shape of the second portion 522 may be substantially the same. The third portion 523 may be fixedly connected between the first portion 521 and the second portion 522.

[0298] Figure 48 is a cross-sectional schematic diagram of one embodiment of the structure shown in Figure 45 cut along F1-F1. Figure 49 is a cross-sectional schematic diagram of one embodiment of the structure shown in Figure 45 cut along F2-F2. Figure 50 is a cross-sectional schematic diagram of one embodiment of the structure shown in Figure 45 cut along F3-F3.

[0299] As shown in Figures 48 to 50, the first portion 521 can be located between the first connecting portion 514 and the first side plate 12 of the base 10, and is movably connected between the first connecting portion 514 and the first side plate 12. The second portion 522 can be located between the second connecting portion 515 and the second side plate 13 of the base 10, and is movably connected between the second connecting portion 515 and the second side plate 13. The third portion 523 can be located on the side of the carrier 51 facing the light inlet aperture 20a. In other embodiments, the third portion 523 can also be located on the side of the carrier 51 facing away from the light inlet aperture 20a.

[0300] For example, the first portion 521 may have a first notch 521a on the side facing the first connecting portion 514. The first connecting portion 514 of the carrier 51 may be installed in the first notch 521a of the first portion 521, that is, the first portion 521 may partially surround the first connecting portion 514. The first connecting portion 514 may be rotatably connected to the first portion 521 by a plurality of first ball bearings 551.

[0301] For example, the second portion 522 may have a second notch 522a on the side facing the second connecting portion 515. The bottom surface of the second notch 522a may have a second guide groove 5221. The second guide groove 5221 may communicate with the second notch 522a. The second connecting portion 515 of the carrier 51 may be installed within the second notch 522a of the second portion 522; that is, the second portion 522 may partially surround the second connecting portion 515. The opening of the second guide groove 5221 may face the second connecting portion 515 and be disposed opposite to the second sliding groove 5152 of the second connecting portion 515. The second connecting portion 515 may be rotatably connected to the second portion 522 via a plurality of second ball bearings 552.

[0302] For example, the center of the circle containing the centers of the plurality of first balls 551 can be a first rotation center O1. The first connecting portion 514 of the carrier 51 can rotate relative to the first portion 521 of the guide bracket 52 about the first rotation center O1. The center of the circle containing the centers of the plurality of second balls 552 constitutes a second rotation center O2. The second connecting portion 515 of the carrier 51 can rotate relative to the second portion 522 of the guide bracket 52 about the second rotation center O2. The straight line connecting the first rotation center O1 and the second rotation center O2 can coincide with the first axis R1. The first axis R1 can be parallel to a third direction Y. The first axis R1 can be located on the side of the mounting slope 511a facing the mounting side 51b.

[0303] Please refer again to Figures 48 to 50. The third guide groove 5231 and the fourth guide groove 5232 can both be formed in the first part 521. The fifth guide groove 5233 and the sixth guide groove 5234 can both be formed in the second part 522. The opening orientations of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 can be the same, and all opposite to the opening orientation of the first guide groove 5211. The arrangement direction of the third guide groove 5231 and the fourth guide groove 5232 can be parallel to the first direction Z. The arrangement direction of the fifth guide groove 5233 and the sixth guide groove 5234 can be parallel to the first direction Z. In the first direction Z, the third guide groove 5231 and the fourth guide groove 5232 can be located on opposite sides of the first notch 521a. The fifth guide groove 5233 and the sixth guide groove 5234 can be located on opposite sides of the second notch 522a.

[0304] Exemplarily, the first slide groove 142 and the second slide groove 143 can both be formed at the end of the first side plate 12 of the base 10 facing away from the third side plate 14. The third slide groove 144 and the fourth slide groove 145 can both be formed at the end of the second side plate 13 of the base 10 facing away from the third side plate 14. The first slide groove 142 can be disposed opposite to the third guide groove 5231. The second slide groove 143 can be disposed opposite to the fourth guide groove 5232. The third slide groove 144 can be disposed opposite to the fifth guide groove 5233. The fourth slide groove 145 can be disposed opposite to the sixth guide groove 5234. The openings of the first slide groove 142, the second slide groove 143, the third slide groove 144, and the fourth slide groove 145 of the base 10 can be correspondingly disposed opposite to the openings of the third guide groove 5231, the fourth guide groove 5232, the fifth guide groove 5233, and the sixth guide groove 5234 of the guide bracket 52, forming a plurality of ball grooves. The four third balls 561 can be located one-to-one in multiple grooves and guide slots. At this time, the guide bracket 52 can be rotatably connected to the base 10 through the multiple third balls 561.

[0305] For example, the centers of the plurality of third balls 561 can be located on the same plane. The center of the circle containing the centers of the plurality of third balls 561 is the third rotation center O3, which is also the center of the second set of support members 56. The second shaft R2 can pass perpendicularly through the plane containing the centers of the plurality of third balls 561. The second shaft R2 can also pass through the third rotation center O3. At this time, the guide bracket 52 can rotate relative to the base 10 around the second shaft R2. The third rotation center O3 can be located on the side of the mounting slope 511a of the carrier 51 facing the light inlet hole 20a and the light outlet hole 20b, that is, on the mounting side 51b of the mounting slope 511a. The second shaft R2 can pass through the mounting slope 511a and is parallel to the second direction X (that is, the second direction X in this embodiment).

[0306] Figure 51 is a cross-sectional view of one embodiment of the image stabilization motor 1a shown in Figure 45, cut along F4-F4. Figure 52 is a cross-sectional view of one embodiment of the image stabilization motor 1a shown in Figure 45, cut along F5-F5. Figure 53 is a cross-sectional view of some embodiments of the assembly structure of the image stabilization motor 1a and the image stabilization lens group 1b shown in Figure 45.

[0307] As shown in Figures 51 to 53, the first set of magnetic components 53 can be fixed to the second surface 5112 of the support portion 511 of the carrier 51. The first set of magnetic components 53 can be located on the side of the carrier 51 facing away from the light-entry hole 20a. The first driving coil 32a and the third position sensor 333 can both be fixed to the main body plate 311 of the circuit board 31 and are arranged opposite to the first set of magnetic components 53. The second set of magnetic components 54 may include a first sub-magnetic component 541 and a second sub-magnetic component 542. The second driving coil 32b may include a first coil 321 and a second coil 322. The specific arrangement of the first sub-magnetic component 541, the second sub-magnetic component 542, the first coil 321, the second coil 322, the first position sensor 331, and the second position sensor 332 is roughly the same as that in the first embodiment, and will not be described again here.

[0308] Exemplarily, the image stabilization lens group 1b can be mounted on the carrier 51. The image stabilization lens group 1b can have positive optical power. The image stabilization lens group 1b can include an optical folding element 104 and a first lens 105. The optical folding element 104 can be mounted in the mounting space 51a of the carrier 51. The optical folding element 104 can be fixedly connected to the carrier 51 by means of adhesive bonding or the like. The first lens 105 can have positive optical power. The first lens 105 can be located on the side of the carrier 51 near the light inlet aperture 20a. The first lens 105 can be fixedly connected to the top of the carrier 51 by means of adhesive bonding or the like. The system focal point of the image stabilization lens group 1b can be located on the side of the mounting ramp 511a of the carrier 51 facing the mounting side 51b. Exemplarily, the optical folding element 104 can be a reflecting plane mirror. In other embodiments, the optical folding element 104 can also be a reflecting prism. In some other embodiments, the image stabilization lens group 1b can also include a second lens (not shown). The second lens can be located on the side of the carrier 51 near the light outlet aperture 20b. The second lens can be fixedly connected to the end of the carrier 51 near the light exit hole 20b by means of adhesive bonding or other methods. The second lens 106 can have negative optical power. The image stabilization lens group 1b can have positive optical power.

[0309] Exemplarily, the optical input axis T1 of the image stabilization lens group 1b can pass through the light input hole 20a and the mounting slope 511a. The optical input axis T1 can be parallel to the first direction Z (also the first direction Z in this embodiment). The optical output axis T2 of the image stabilization lens group 1b can pass through the mounting slope 511a and the light output hole 20b. The optical output axis T2 can be parallel to the second direction X (also the second direction X in this embodiment). The first axis R1 can be perpendicular to the plane containing the optical input axis T1 and the optical output axis T2. The second axis R2 can coincide with the optical output axis T2. Exemplarily, the first axis R1 and the second axis R2 can intersect at a fifth intersection point G5. The first axis R1 and the second axis R2 can be perpendicular to each other. The fifth intersection point G5 can be located on the mounting side 51b of the mounting slope 511a. The winding plane of the first drive coil 32a can be perpendicular to the optical input axis T1. In other embodiments, the first axis R1 may not intersect the second axis R2. This application does not limit this.

[0310] Please refer again to Figures 51 to 53. When a signal is applied to the first drive coil 32a, the first drive coil 32a can cooperate with the first set of magnetic components 53 to generate a force parallel to the second direction X, thereby driving the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1. At this time, the image stabilization lens group 1b can rotate relative to the base 10 around the first axis R1 under the action of the carrier 51.

[0311] The first drive coil 32a and the first set of magnetic components 53 can together constitute the first drive mechanism. The third position sensor 333 can cooperate with the first set of magnetic components 53 to detect the change in the magnetic field of the first set of magnetic components 53 when the carrier 51 rotates around the first axis R1 at different angles, so as to detect the angle of rotation of the carrier 51 around the first axis R1. At this time, the first set of magnetic components 53 and the third position sensor 333 can together constitute the second detection component 62. The first set of magnetic components 53 can constitute the third magnetic component 621 of the second detection component 62. In this way, the first set of magnetic components 53 can achieve multiple uses. On the one hand, it can cooperate with the first drive coil 32a to drive the carrier 51 to rotate around the first axis R1; on the other hand, it can cooperate with the third position sensor 333 to detect the angle of rotation of the carrier 51 around the first axis R1. This eliminates the need for additional magnetic components to cooperate with the third position sensor 333 in the anti-shake motor 1a, which helps to reduce the weight of the mover 50, achieve large-angle anti-shake, save the manufacturing cost of the anti-shake motor 1a, save the internal space of the anti-shake motor 1a, and achieve miniaturization of the anti-shake motor 1a.

[0312] Please refer again to Figures 51 to 53. When a signal is applied to the second drive coil 32b, the first coil 321 can cooperate with the first sub-magnetic element 541 to generate a first driving force parallel to the first direction Z. The second coil 322 can cooperate with the second sub-magnetic element 542 to generate a second driving force parallel to the first direction Z. The direction of the first driving force can be opposite to the direction of the second driving force, thereby driving the carrier 51 to rotate relative to the base 10 around the second axis R2, along with the guide bracket 52. Under the action of the carrier 51, the image stabilization lens group 1b can rotate relative to the base 10 around the second axis R2.

[0313] The second set of magnetic components 54 and the second drive coil 32b together constitute the second drive mechanism of the anti-shake motor 1a. Specifically, the second drive coil 32b, the first sub-magnetic component 541, and the second sub-magnetic component 542 together form the second drive mechanism. The first position sensor 331 cooperates with the first sub-magnetic component 541, and the second position sensor 332 cooperates with the second sub-magnetic component 542 to jointly detect the change in magnetic field when the carrier 51 rotates around the second axis R2 at different angles, thereby detecting the angle of rotation of the carrier 51 around the second axis R2. At this time, the second set of magnetic components 54 can also cooperate with the second drive coil 32b to constitute the first detection component 61. Specifically, the second drive coil 32b, the first sub-magnetic component 541, and the second sub-magnetic component 542 together form the first detection component 61. The first sub-magnetic component 541 can constitute the first magnetic component 611 of the first detection component 61. The second magnetic component 542 can constitute the second magnetic component 612 of the first detection component 61. In this way, both the first sub-magnetic component 541 and the second sub-magnetic component 542 can achieve multiple uses. On the one hand, they can cooperate with the second drive coil 32b to drive the carrier 51 to rotate around the second axis R2; on the other hand, they can cooperate with the first position sensor 331 and the second position sensor 332 respectively to detect the angle of rotation of the carrier 51 around the second axis R2. This eliminates the need for additional magnetic components for the anti-shake motor 1a to cooperate with the first position sensor 331 and the second position sensor 332, which helps to reduce the weight of the mover 50, achieve large-angle anti-shake, save manufacturing costs of the anti-shake motor 1a, save internal space of the anti-shake motor 1a, and achieve miniaturization of the anti-shake motor 1a.

[0314] For example, the input terminal of the first position sensor 331 can be connected in parallel with the input terminal of the second position sensor 332. The output terminal of the first position sensor 331 can be connected in parallel with the output terminal of the second position sensor 332. The first position sensor 331 may include a first input terminal 3311, a first positive output terminal 3312, and a first negative output terminal 3313. The second position sensor 332 may include a second input terminal 3321, a second positive output terminal 3322, and a second negative output terminal 3323 (see Figure 37). The first input terminal 3311 can be connected in parallel with the second input terminal 3321. When the magnetic field direction of the first magnetic element 611 is symmetrically arranged with the magnetic field direction of the second magnetic element 612, the first positive output terminal 3312 can be connected in parallel with the second negative output terminal 3323, and the first negative output terminal 3313 can be connected in parallel with the second positive output terminal 3322. When the magnetic field direction of the first magnetic element 611 is the same as that of the second magnetic element 612, the first positive output terminal 3312 can be connected in parallel with the second positive output terminal 3322, and the first negative output terminal 3313 can be connected in parallel with the second negative output terminal 3323.

[0315] It is understandable that, compared to some image stabilization motors where the mover drives the image stabilization lens group to rotate relative to the stator around a first axis and around a second axis to achieve optical image stabilization, the first axis is parallel to a third direction. The first axis is located on the mounting slope of the mover. The second axis is parallel to the first direction. This results in a larger focus shift when the image stabilization motor drives the image stabilization lens group to rotate around the second axis for optical image stabilization, leading to a significant decrease in the modulation transfer function of the entire camera module, lower stabilization accuracy, and affecting image quality. In this embodiment, the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate relative to the stator around a second axis R2, which is parallel to the second direction X. Thus, when the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate around the second axis R2, the exit surface of the image stabilization component 1 can always remain perpendicular to the light output axis T2. This effectively reduces the tilt angle between the image stabilization component 1 and the focusing component 2, reduces the focus offset, and helps improve the image stabilization accuracy of the entire camera module 100. The camera module 100 has higher optical quality, which is beneficial to improving image quality. Meanwhile, in this embodiment, the first axis R1 of the image stabilization motor 1a is located on the side of the mounting inclined surface 511a facing the light inlet aperture 20a and the light outlet aperture 20b, that is, the side of the mounting inclined surface 511a facing the mounting side 51b. The first axis R1 is parallel to the third direction Y. When the image stabilization lens group 1b has positive optical power, the system focus of the image stabilization lens group 1b can be located on the mounting side 51b of the mounting inclined surface 511a. That is, both the system focus of the image stabilization lens group 1b and the first axis R1 can be located on the mounting side 51b of the mounting inclined surface 511a. In this way, the distance between the first axis R1 and the system focus of the image stabilization lens group 1b is relatively close. When the mover 50 of the image stabilization motor 1a drives the image stabilization lens group 1b to rotate around the first axis R1, the focus offset is small. This can effectively reduce the impact of focus offset on the modulation transfer function, which is beneficial to improving the image stabilization accuracy of the entire camera module 100 and improving the image quality.

[0316] In other words, the image stabilization motor 1a in this embodiment can effectively improve the overall image stabilization accuracy of the image stabilization motor 1a and reduce the impact on the modulation transfer function by setting the first axis R1 to be parallel to the third direction Y and the second axis R2 to be parallel to the second direction X, and the first axis R1 is located on the side of the mounting slope 511a of the mover 50 facing the mounting side 51b. This is beneficial to improving the imaging quality of the camera module 100.

[0317] Secondly, the anti-shake motor 1a in this embodiment also includes a first detection component 61. The first detection component 61 may include a first position sensor 331, a second position sensor 332, a first magnetic element 611 (also known as the first sub-magnetic element 541 in this embodiment), and a second magnetic element 612 (also known as the second sub-magnetic element 542 in this embodiment). Both the first position sensor 331 and the second position sensor 332 can be fixed to the circuit board 31, that is, fixed to the base 10. Both the first magnetic element 611 and the second magnetic element 612 can be fixed to the carrier 51. By cooperating with the first position sensor 331 and the first magnetic element 611, and by cooperating with the second position sensor 332 and the second magnetic element 612, the magnetic field changes when the carrier 51 rotates around the second axis R2 at different angles can be detected, so as to detect the angle of rotation of the carrier 51 around the second axis R2. The input terminal of the first position sensor 331 can be connected in parallel with the input terminal of the second position sensor 332. The output terminal of the first position sensor 331 can also be connected in parallel with the output terminal of the second position sensor 332. The first position sensor 331 can perform differential calculations with the second position sensor 332 to jointly detect the angle of rotation of the carrier 51 around the second axis R2. In contrast, a typical image stabilization motor uses only one set of position sensors and magnetic components (e.g., only the first position sensor and the first magnetic component 611) to detect the angle of rotation of the carrier around the second axis. During detection, the first position sensor is easily affected by changes in the magnetic field of the first magnetic component 611 caused by the carrier's rotation around the first axis, leading to reduced detection accuracy of the first position sensor and affecting the image stabilization accuracy of the motor. In this embodiment, two position sensors 33 (i.e., the first position sensor 331 and the second position sensor 332 in this embodiment) are respectively configured to cooperate with two magnetic components (i.e., the first sub-magnetic component 541 and the second sub-magnetic component 542 in this embodiment) to jointly detect the angle of rotation of the carrier 51 around the second axis R2. Furthermore, the first position sensor 331 and the second position sensor 332 reduce the inductive crosstalk problem caused by the first set of magnetic components 53 and the second set of magnetic components 54 being installed on the carrier 51 through differential operation, thereby offsetting the influence of the magnetic field change caused by the rotation of the carrier 51 around the first axis R1 on the first position sensor 331 and the second position sensor 332, thereby improving the control accuracy of the anti-shake motor 1a and improving the anti-shake accuracy.

[0318] In some embodiments, as shown in FIG53, the support portion 511 of the carrier 51 may also be provided with an anti-collision protrusion 5115 on the side facing away from the light-emitting hole 20b. The third side plate 14 of the base 10 may also be provided with a limiting hole 147. At least a portion of the anti-collision protrusion 5115 of the carrier 51 may be located within the limiting hole 147. The anti-collision protrusion 5115 may be spaced apart from the hole wall of the limiting hole 147. In this way, when the carrier 51 rotates relative to the base 10 around the first axis R1, the anti-collision protrusion 5115 may cooperate with the limiting hole 147, thereby effectively avoiding the problem that the angle of rotation of the carrier 51 relative to the base 10 around the first axis R1 is too large, which would cause the image stabilization lens group 1b to collide with the stator of the image stabilization motor 1a and be damaged, thus helping to extend the service life of the camera module.

[0319] In some embodiments, as shown in Figures 48 and 49, the bottom 22 of the housing 20 may have a first extension 221 and a second extension 222 near the light emission hole 20b (Figure 46 also shows the first extension 221 and the second extension 222 of the bottom 22). The first extension 221 may be disposed toward the first sidewall 512 of the carrier 51. The second extension 222 may be disposed toward the second sidewall 513 of the carrier 51. The first extension 221 may have a first limiting protrusion 2211. The end of the first sidewall 512 of the carrier 51 near the light emission hole 20b may have a first limiting groove 5122. At least a portion of the first limiting protrusion 2211 may be located within the first limiting groove 5122. The first limiting protrusion 2211 may be spaced apart from the groove wall of the first limiting groove 5122. The second extension 222 may have a second limiting protrusion 2221. A second limiting groove 5132 may be provided at the end of the second sidewall 513 of the carrier 51 near the light-emitting hole 20b. At least a portion of the second limiting protrusion 2221 may be located within the second limiting groove 5132. The second limiting protrusion 2221 may be spaced apart from the groove wall of the second limiting groove 5132. It should be understood that Figure 47 also illustrates the first limiting groove 5122 and the second limiting groove 5132. In this way, when the carrier 51 rotates relative to the base 10 around the second axis R2, the first limiting protrusion 2211 can cooperate with the first limiting groove 5122, and the second limiting protrusion 2221 can cooperate with the second limiting groove 5132. This can effectively prevent the carrier 51 from rotating too much relative to the base 10 around the second axis R2, which could cause the image stabilization lens group 1b to collide with the stator of the image stabilization motor 1a and be damaged. This is beneficial to extending the service life of the camera module.

[0320] In other embodiments, the first drive coil 32a may also form a second drive mechanism with the first set of magnetic elements 53. The second drive coil 32b may also form a first drive mechanism with the second set of magnetic elements 54.

[0321] Fourth Embodiment: Figure 54 is a structural schematic diagram of the anti-shake motor 1a shown in Figure 10 in the fourth embodiment. Figure 55 is an exploded structural schematic diagram of the structure shown in Figure 54 in some embodiments. For ease of understanding, the housing 20 of the anti-shake motor 1a is hidden in Figure 54.

[0322] As shown in Figures 54 and 55, the structure of the anti-shake motor 1a in this embodiment is largely the same as that shown in Figure 45, and the identical parts will not be described again. The following describes some differences between the two embodiments. Exemplarily, both the first drive coil 32a and the second drive coil 32b can be fixed to the third extension plate 314 of the circuit board 31. The second drive coil 32b may include the first coil 321 and the second coil 322. The first drive coil 32a can be located between the first coil 321 and the second coil 322. The arrangement direction of the first coil 321, the first drive coil 32a, and the second coil 322 can be parallel to the third direction Y.

[0323] For example, the first position sensor 331 can be fixed to the first extension plate 312 of the circuit board 31. The second position sensor 332 can be fixed to the second extension plate 313 of the circuit board 31. The arrangement direction of the first position sensor 331 and the second position sensor 332 can be parallel to the third direction Y. The third position sensor 333 can be fixed to the third extension plate 314 of the circuit board 31. The third position sensor 333 can be located in the coil hole of the first drive coil 32a.

[0324] Figure 56 is an exploded structural diagram of the mover 50 shown in Figure 55 in some embodiments. Figure 57 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 54 cut along G1-G1.

[0325] As shown in Figures 55 to 57, the first set of magnetic components 53 can be fixed to the carrier 51 and located on the side of the carrier 51 facing away from the light-emitting hole 20b (see Figure 31). The arrangement direction of the first set of magnetic components 53 and the mounting inclined surface 511a can be parallel to the second direction X. The first set of magnetic components 53 can be simultaneously arranged opposite to the first driving coil 32a, the second driving coil 32b, and the third position sensor 333.

[0326] By way of example, the image stabilization motor 1a may not include the second set of magnetic components. The image stabilization motor 1a may also include a first magnetic component 611 and a second magnetic component 612. The first magnetic component 611 may be fixed to the first sidewall 512 of the carrier 51. The projection of the first position sensor 331 onto the plane where the first magnetic component 611 is located overlaps with at least a portion of the first magnetic component 611. The second magnetic component 612 may be fixed to the second sidewall 513 of the carrier 51. The projection of the second position sensor 332 onto the plane where the second magnetic component 612 is located may overlap with at least a portion of the second magnetic component 612.

[0327] As shown in Figure 57, when a signal is applied to the first driving coil 32a, the first driving coil 32a can cooperate with the first set of magnetic components 53 to generate a force parallel to the first direction Z, thereby driving the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1. At this time, the first driving coil 32a and the first set of magnetic components 53 can constitute a first driving mechanism. The third position sensor 333 can cooperate with the first set of magnetic components 53 to detect the change in the magnetic field of the first set of magnetic components 53 when the carrier 51 rotates around the first axis R1 at different angles, so as to detect the angle of rotation of the carrier 51 around the first axis R1. The third position sensor 333 and the first set of magnetic components 53 can constitute a second detection component 62. At this time, the first set of magnetic components 53 can constitute the third magnetic component 621 of the second detection component 62. In this way, the first set of magnetic components 53 can achieve multiple uses. On the one hand, it can cooperate with the first drive coil 32a to drive the carrier 51 to rotate around the first axis R1; on the other hand, it can cooperate with the third position sensor 333 to detect the angle of rotation of the carrier 51 around the first axis R1. This eliminates the need for additional magnetic components to cooperate with the third position sensor 333 in the anti-shake motor 1a, which helps to reduce the weight of the mover 50, achieve large-angle anti-shake, save the manufacturing cost of the anti-shake motor 1a, save the internal space of the anti-shake motor 1a, and achieve miniaturization of the anti-shake motor 1a.

[0328] As shown in Figure 57, when a signal is applied to the second driving coil 32b, the second coil 322 can cooperate with the first set of magnetic components 53 to generate a first driving force parallel to the first direction Z. The second coil 322 can cooperate with the first set of magnetic components 53 to generate a second driving force parallel to the first direction Z. The direction of the first driving force can be opposite to the direction of the second driving force, thereby driving the carrier 51 to rotate relative to the base 10 around the second axis R2 along with the guide bracket 52. At this time, the second driving coil 32b and the first set of magnetic components 53 can form a second driving mechanism. The first position sensor 331 can cooperate with the first magnetic component 611, and the second position sensor 332 can cooperate with the second magnetic component 612 to detect the changes in the magnetic fields of the first magnetic component 611 and the second magnetic component 612 when the carrier 51 rotates around the second axis R2 at different angles, so as to jointly detect the angle of rotation of the carrier 51 around the second axis R2. The second driving coil 32b, the first magnetic component 611, and the second magnetic component 612 can together form a first detection component 61.

[0329] It is understood that in this embodiment, the image stabilization motor 1a is fixed to the carrier 51 by the first set of magnetic components 53, which are located on the side of the carrier 51 facing away from the light emission hole 20b. The first drive coil 32a and the second drive coil 32b are both arranged opposite to the first set of magnetic components 53. The first set of magnetic components 53 can cooperate with the first drive coil 32a to drive the carrier 51 to rotate around the first axis R1. The first set of magnetic components 53 can also cooperate with the second drive coil 32b to drive the carrier 51 to rotate around the second axis R2. Thus, by positioning the first drive coil 32a and the second drive coil 32b on the side of the carrier 51 facing away from the light emission hole 20b and sharing the first set of magnetic components 53, the carrier 51 can be driven to rotate around the first axis R1 and the second axis R2 respectively. This helps to reduce the size of the image stabilization motor 1a in the second direction X, achieving a miniaturized design of the image stabilization motor 1a.

[0330] Fifth Embodiment: Figure 58 is a structural schematic diagram of the anti-shake motor 1a shown in Figure 10 in the fifth embodiment. Figure 59 is an exploded structural schematic diagram of the structure shown in Figure 58 in some embodiments. For ease of understanding, the housing 20 of the anti-shake motor 1a is hidden in Figure 58.

[0331] As shown in Figures 58 and 59, the structure of the anti-shake motor 1a in this embodiment is largely the same as that shown in Figure 45, and the identical parts will not be described again. The following describes some differences between the two embodiments. Exemplarily, both the first drive coil 32a and the third position sensor 333 can be fixed to the main body plate 311 of the circuit board 31. The third position sensor 333 can be located inside the coil hole of the first drive coil 32a. The second drive coil 32b can include the first coil 321 and the second coil 322. Both the first coil 321 and the second coil 322 can be fixed to the third extension plate 314 of the circuit board 31. The first position sensor 331 can be fixed to the first extension plate 312 of the circuit board 31. The second position sensor 332 can be fixed to the second extension plate 313 of the circuit board 31.

Figure 62 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 58 cut along G3-G3.

[0333] As shown in Figures 60 to 62, the first set of magnetic components 53 can be fixed to the second surface 5112 of the support portion 511 of the carrier 51, that is, the first set of magnetic components 53 can be fixed to the carrier 51 and located on the side of the carrier 51 facing away from the light-entry hole 20a (see Figure 31). The first set of magnetic components 53 can be arranged opposite to the first driving coil 32a and the third position sensor 333. The winding plane of the first driving coil 32a can be perpendicular to the first direction Z. The polarization direction of the first set of magnetic components 53 can be parallel to the second direction X. The second set of magnetic components 54 can be fixed to the first surface 5111 of the support portion 511 of the carrier 51, that is, the second set of magnetic components 54 can be fixed to the carrier 51 and located on the side of the carrier 51 facing away from the light-exit hole 20b (see Figure 31). The second set of magnetic components 54 can be arranged opposite to the second driving coil 32b. The polarization direction of the second set of magnetic components 54 can be parallel to the first direction Z.

[0334] Exemplarily, the image stabilization motor 1a may further include a first magnetic element 611 and a second magnetic element 612. The first magnetic element 611 may be fixed to a first sidewall 512 of the carrier 51. The second magnetic element 612 may be fixed to a second sidewall 513 of the carrier 51. The arrangement direction of the first magnetic element 611 and the second magnetic element 612 may be parallel to a third direction Y. The first magnetic element 611 may be disposed opposite to a first position sensor 331. The second magnetic element 612 may be disposed opposite to a second position sensor 332.

[0335] For example, when a signal is applied to the first drive coil 32a, the first drive coil 32a can cooperate with the first set of magnetic elements 53 to generate a force parallel to the second direction X, thereby driving the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1. At this time, the first drive coil 32a and the first set of magnetic elements 53 can constitute a first drive mechanism. The third position sensor 333 can cooperate with the first set of magnetic elements 53 to detect the changes in the magnetic field of the first set of magnetic elements 53 when the carrier 51 rotates around the first axis R1 at different angles. The third position sensor 333 and the first set of magnetic elements 53 can constitute a second detection component 62. At this time, the first set of magnetic elements 53 can constitute a third magnetic element 621 of the second detection component 62.

[0336] For example, when a signal is applied to the second drive coil 32b, the first coil 32 of the second drive coil 32b can cooperate with the second set of magnetic elements 54 to generate a first driving force parallel to the first direction Z. The second coil 32 can cooperate with the second set of magnetic elements 54 to generate a second driving force parallel to the first direction Z. The direction of the first driving force can be opposite to the direction of the second driving force, thereby driving the carrier 51 to rotate relative to the base 10 around the second axis R2 along with the guide bracket 52. At this time, the second drive coil 32b and the second set of magnetic elements 54 can constitute a second drive mechanism. The first position sensor 331 can cooperate with the first magnetic element 611, and the second position sensor 332 can cooperate with the second magnetic element 612 to detect the changes in the magnetic fields of the first magnetic element 611 and the second magnetic element 612 when the carrier 51 rotates around the second axis R2 at different angles, so as to jointly detect the angle of rotation of the carrier 51 around the second axis R2. The second drive coil 32b, the first magnetic element 611, and the second magnetic element 612 can together constitute a first detection component 61.

[0337] In some embodiments, the anti-shake motor 1a may further include a reinforcing plate 34. The reinforcing plate 34 may be fixedly connected to the surface of the third extension plate 314 facing away from the carrier 51. The third extension plate 314 may be provided with a clearance through hole 3141. The clearance through hole 3141 may be directly opposite the coil hole of the second drive coil 32b. Part of the reinforcing plate 34 may pass through the clearance through hole 3141 of the third extension plate 314 and extend into the coil hole of the second drive coil 32b. In this way, the reinforcing plate 34 can also support the second drive coil 32b, which is beneficial to improving the overall structural stability of the circuit assembly 30.

Figure 64 is an exploded structural schematic diagram of the structure shown in Figure 63 in some embodiments. For ease of understanding, the housing 20 of the anti-shake motor 1a is hidden in Figure 63.

[0339] As shown in Figures 63 and 64, the structure of the anti-shake motor 1a in this embodiment is largely the same as that shown in Figure 58, and the identical parts will not be described again. The following describes some differences between the two embodiments. Exemplarily, the first drive coil 32a can be fixed to the third extension plate 314 of the circuit board 31. The second drive coil 32b can be fixed to the main body plate 311 of the circuit board 31. The first drive coil 32a may include a third coil 323 and a fourth coil 324. The arrangement direction of the third coil 323 and the fourth coil 324 can be parallel to the third direction Y. The third position sensor 333 can be located between the third coil 323 and the fourth coil 324.

[0340] For example, the first position sensor 331 can be fixed to the first extension plate 312 of the circuit board 31.

Figure 66 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 63 cut along G4-G4. Figure 67 is a cross-sectional structural diagram of one embodiment of the structure shown in Figure 63 cut along G5-G5.

[0342] As shown in Figures 65 to 67, the first set of magnetic components 53 can be fixed to the carrier 51 and located on the side of the carrier 51 facing away from the light-emitting hole 20b (see Figure 31). The arrangement direction of the first set of magnetic components 53 and the mounting inclined surface 511a can be parallel to the second direction X. The first set of magnetic components 53 can be arranged opposite to the first driving coil 32a and the third position sensor 333. The winding plane of the first driving coil 32a can be perpendicular to the second direction X. The polarization direction of the first set of magnetic components 53 can be parallel to the first direction Z. The second set of magnetic components 54 can be fixed to the support portion 511 of the carrier 51 and located on the side of the carrier 51 facing away from the light-entry hole 20a (see Figure 31). The arrangement direction of the second set of magnetic components 54 and the mounting inclined surface 511a can be parallel to the first direction Z. The second set of magnetic components 54 can be arranged opposite to the second driving coil 32b. The polarization direction of the second set of magnetic components 54 can be parallel to the third direction Y.

[0343] For example, when a signal is applied to the first drive coil 32a, the first drive coil 32a can cooperate with the first set of magnetic elements 53 to generate a force parallel to the first direction Z, thereby driving the carrier 51 to rotate relative to the guide bracket 52 around the first axis R1. At this time, the first drive coil 32a and the first set of magnetic elements 53 can constitute a first drive mechanism. The third position sensor 333 can cooperate with the first set of magnetic elements 53 to detect the changes in the magnetic field of the first set of magnetic elements 53 when the carrier 51 rotates around the first axis R1 at different angles. The third position sensor 333 and the first set of magnetic elements 53 can constitute a second detection component 62. At this time, the first set of magnetic elements 53 can constitute a third magnetic element 621 of the second detection component 62.

[0344] For example, when a signal is applied to the second drive coil 32b, the second drive coil 32b can cooperate with the second set of magnetic elements 54 to generate a force parallel to the third direction Y, thereby driving the carrier 51 to rotate relative to the base 10 around the second axis R2 along with the guide bracket 52. At this time, the second drive coil 32b and the second set of magnetic elements 54 can constitute a second drive mechanism. The first position sensor 331 can cooperate with the first magnetic element 611, and the second position sensor 332 can cooperate with the second magnetic element 612 to detect the changes in the magnetic fields of the first magnetic element 611 and the second magnetic element 612 when the carrier 51 rotates around the second axis R2 at different angles, so as to jointly detect the angle of rotation of the carrier 51 around the second axis R2. The second drive coil 32b, the first magnetic element 611, and the second magnetic element 612 can together constitute a first detection component 61.

[0345] In some embodiments, please refer to FIG. 68, which is a schematic diagram of the circuit assembly 30 shown in FIG. 64 in some embodiments. The second drive coil 32b may further include a first coil (not shown) and a second coil (not shown). Both the first coil and the second coil can be fixed to the main body plate 311. The arrangement direction of the first coil and the second coil can be parallel to the third direction Y. When a signal is applied to the second drive coil 32b, the first coil of the second drive coil 32b can cooperate with the second set of magnetic elements 54 to generate a first driving force parallel to the first direction Z. The second coil can cooperate with the second set of magnetic elements 54 to generate a second driving force parallel to the first direction Z. The direction of the first driving force is opposite to the direction of the second driving force, thereby driving the carrier 51 to rotate relative to the guide bracket 52 about the second axis R2.
