Description

Image stabilization motor, camera module and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202510066973.3, filed with the China National Intellectual Property Administration on January 15, 2025, entitled "Shake Stabilization Motor, Camera Module and Electronic Device", and priority to Chinese Patent Application No. 202510451225.7, filed with the China National Intellectual Property Administration on April 10, 2025, entitled "Shake Stabilization Motor, Camera Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of shooting equipment technology, and in particular to a stabilization motor, camera module and electronic equipment. Background Technology

[0003] With the upgrading of consumption and the rapid development of electronic devices, consumers have increasingly higher demands for camera modules, among which telephoto lenses have become a crucial part of the user's photography experience. Existing periscope camera modules typically feature optical image stabilization (OIS) to improve image quality. With the widespread adoption of telephoto photography in smartphones, consumers' requirements for telephoto optical image stabilization are also increasing. Among the image stabilization solutions for telephoto modules, prism stabilization has the advantages of simple structure, small size, and low cost, and is therefore widely used.

[0004] In prism image stabilization, light enters the prism along a first direction and exits along a second direction. A third direction is perpendicular to both the first and second directions. An image stabilization motor drives the prism to rotate around the second and / or third direction to achieve image stabilization. Currently, when the image stabilization motor drives the prism to rotate around the second direction, there is significant friction between the moving and stationary components of the prism image stabilization motor, affecting the motor's control accuracy and image stabilization effect. Therefore, reducing the friction between the moving and stationary components and improving the motor's control accuracy and image stabilization effect are urgent problems to be solved. Summary of the Invention

[0005] This application provides a stabilization motor, camera module, and electronic device with good optical image stabilization performance.

[0006] In a first aspect, embodiments of this application provide a stabilization motor. The stabilization motor has an inlet aperture and an outlet aperture. Light propagates into the stabilization motor through the inlet aperture along a first direction, and light propagates out of the stabilization motor through the outlet aperture along a second direction. The first direction and the second direction are different. The stabilization motor includes a base and a first bracket. The first bracket is movably connected to the base and is capable of rotating relative to the base around a first axis. The first axis is parallel to the second direction. The stabilization motor also includes positioning balls. The positioning balls are movably connected between the base and the first bracket. The base has a positioning groove. The positioning groove includes three limiting surfaces. The three limiting surfaces form the three sides of a triangular pyramid. The positioning balls and the positioning groove are arranged along the second direction. The positioning balls are movably connected within the positioning groove and simultaneously contact the three limiting surfaces. The first axis passes through the center of the space enclosed by the three limiting surfaces.

[0007] Understandably, this application achieves positioning of the first axis through the cooperation of positioning balls and positioning grooves, allowing the first bracket to rotate around the first axis when it is movably connected to the base. The positioning balls and positioning grooves in this application achieve positioning through point-to-surface contact. Compared to surface-to-surface contact positioning, this point-to-surface contact positioning scheme is less affected by the installation and manufacturing precision of the structural components, making it easier to assemble. Furthermore, the point-to-surface contact has a small contact area, resulting in less friction between the first bracket and the base, reducing the likelihood of jamming when the first bracket moves relative to the base, and improving the accuracy of the anti-shake motor control. In addition, when the positioning balls are movably connected within the positioning grooves, there are always three contact points at any given time, providing better limiting and support for the positioning balls.

[0008] In one possible implementation, along the second direction, the gap D1 between the first bracket and the base, the radius R of the positioning ball, and the depth D2 of the positioning ball in the positioning groove satisfy the following relationship: 0 < D1 < (2R - D2).

[0009] Understandably, this ensures both the reliability and stability of the positioning balls within the positioning groove, while preventing any movement interference between the base and the first support.

[0010] In one possible implementation, the radius R of the positioning ball and the depth D2 of the positioning ball in the positioning groove satisfy the following relationship: 0.01R≤D2≤0.9R.

[0011] In this way, the contact area between the positioning ball and the positioning groove can be within a suitable range, ensuring that the positioning ball can remain stably in the positioning groove during the movement and is not easily dislodged during the process.

[0012] In one possible implementation, the two adjacent limiting surfaces are set at a 60° angle, and the limiting surface and the first axis are also set at a 60° angle. This results in a more regular shape for the positioning groove, making the design and fabrication process easier.

[0013] In one possible implementation, the back plate of the base and the first support are disposed opposite each other along the first axis. The back plate of the base includes a back plate body and a metal insert, the metal insert being embedded in the back plate body and partially exposed thereout. Along the first axis, the metal insert is recessed away from the first support, forming a positioning groove. The hardness of the metal insert is greater than the hardness of the back plate body.

[0014] Understandably, the hardness of the metal insert is greater than that of the backplate body, allowing it to provide better strength for the first support. The metal insert, made of metal, has a lower coefficient of friction compared to the direct friction between the positioning balls and plastic. Connecting the positioning balls to the metal insert further reduces the friction between the first support and the base.

[0015] In one possible implementation, the positioning ball is fixedly connected to the first bracket.

[0016] Understandably, the positioning ball is fixedly connected to the first bracket, and the connection strength between the positioning ball and the first bracket is good. The position of the positioning ball relative to the first bracket is not easy to move. When the anti-shake device detects the position of the first bracket relative to the base, the interference of the positioning ball is small, and the control accuracy of the anti-shake device is good.

[0017] In one possible implementation, the stabilization motor further includes a first support member. The first support member is rotatably connected between the first bracket and the base.

[0018] It is understandable that the first bearing member is rolled between the first support and the base, which helps to reduce the friction between the first bearing member and the base and the first support, thereby helping to reduce the motion friction between the first support and the base.

[0019] In one possible implementation, the first support has a first rolling groove. A first bearing member is partially located within the first rolling groove. The cross-sectional area of ​​the first rolling groove is larger than the cross-sectional area of ​​the first bearing member. A second direction is perpendicular to the plane containing the cross-sectional area of ​​the first rolling groove. And / or, the base has a first support groove, the first bearing member is partially located within the first support groove, the cross-sectional area of ​​the first support groove is larger than the cross-sectional area of ​​the first bearing member, and a second direction is perpendicular to the plane containing the cross-sectional area of ​​the first support groove.

[0020] Understandably, the first support groove and / or the first rolling groove can be used to limit the movement of the first support member. When the first support member is movably connected between the base and the first bracket, the first support groove and / or the first rolling groove can be used to prevent the first support member from detaching from the base or the first bracket. The cross-sectional area of ​​the first support groove is larger than the cross-sectional area of ​​the first support member. The second direction is perpendicular to the plane containing the cross-sectional area of ​​the first support groove. In this way, there can be a larger space within the first support groove to support the rolling of the first support member.

[0021] In one possible implementation, the anti-shake motor further includes a second support member, which is rotatably connected between the first bracket and the base and is spaced apart from the first support member.

[0022] It is understandable that the lines connecting the positions of the positioning ball, the first support component, and the second support component can form a triangle. This results in more stable support between the first bracket and the base.

[0023] In one possible implementation, the line connecting the first support member and the second support member is the first connecting line. The positioning ball, the first support member, and the second support member are not collinear. Along the first direction, the projection of the positioning ball on the first connecting line is located between the first support member and the second support member.

[0024] Understandably, with the first and second support components positioned on either side of the first shaft, the first support is more stable.

[0025] In one possible implementation, the anti-shake motor further includes a lubricating medium connected between the first support member, the base, and the first bracket.

[0026] Understandably, a lubricating medium can further reduce the kinematic friction between the first support and the base. For example, the friction medium can be lubricating oil or grease.

[0027] In one possible implementation, the first support element is a ball bearing.

[0028] Understandably, when the first support component is a ball bearing, compared to a design where the first support component is a roller, the connection area between the ball bearing and the base and the first support can be smaller than that of the roller, which helps to reduce the motion friction between the first support component and the base and the first support.

[0029] In one possible implementation, the first bearing component includes multiple balls.

[0030] Understandably, when there are multiple balls, the bearing area between the first bearing component and the base can be larger, and the bearing area between the first support and the base can be larger, which helps to reduce the reliability risk between the first support and the base.

[0031] In one possible implementation, the image stabilization motor further includes a first sensor and a first detection magnet. One of the first sensor and the first detection magnet is fixed to the base, and the other is fixed to the first bracket. The first sensor and the first detection magnet are used to detect the displacement of the first bracket relative to the base. The first sensor and the first detection magnet are positioned opposite each other along a second direction or a third direction, with the third direction perpendicular to the first and second directions.

[0032] Understandably, the first sensor can be used to detect the magnetic field of the first detection magnet in order to detect the displacement of the first support relative to the base. By setting the first sensor and the first detection magnet, the displacement of the first support relative to the base can be detected. During the anti-shake motor's anti-shake operation, the angle of rotation of the first support around the first axis can be fed back at any time, and the control of the anti-shake motor can achieve closed-loop control.

[0033] In one possible implementation, the anti-shake motor further includes a first drive mechanism for driving the first bracket to rotate relative to the base about a first axis.

[0034] It is understandable that the first drive mechanism can be driven by coil magnets, piezoelectric ceramics, or shape memory alloys.

[0035] In one possible implementation, the first support includes a first arm, a second arm, and a connecting arm. The connecting arm is positioned between the first and second arms along a third direction. A positioning ball is fixed to the connecting arm. The third direction is perpendicular to both the first and second directions. The first driving mechanism includes a first coil and a first magnetic element. One of the first coil and the first magnetic element is fixed to the base, and the other is fixed to the first arm. The first coil faces the first magnetic element.

[0036] Understandably, after the first coil is energized, the first magnetic component can cooperate with the first coil, and the first bracket is subjected to a driving force parallel to the first direction, which drives the first bracket to move. Under the limiting effect of the positioning groove on the positioning ball, the first bracket can rotate around the first axis.

[0037] In one possible implementation, the first driving mechanism further includes a second coil and a second magnetic element, one of which is fixed to the base and the other is fixed to the second arm, with the second coil facing the second magnetic element.

[0038] It is understandable that the first and second arms of the first support can be subjected to forces simultaneously. When the forces on the first and second arms are in opposite directions, the forces on the first and second arms simultaneously provide the first support with torque to rotate around the first axis, resulting in higher driving efficiency.

[0039] In one possible implementation, the anti-shake motor further includes a second bracket and a second drive mechanism. The second bracket is movably connected to the first bracket, and the second drive mechanism is used to drive the second bracket to rotate relative to the first bracket about a second axis. The second axis is perpendicular to both the first and second directions.

[0040] It is understandable that when the anti-shake motor is used to drive the optical path folding element for anti-shake, the second bracket can be used to support the optical path folding element, which can rotate around the first axis and / or around the second axis, thus achieving high anti-shake accuracy.

[0041] In one possible implementation, the second drive mechanism includes a third coil and a third magnetic element, one of which is fixed to the base, and the other is fixed to the second bracket. Along a first or second direction, the third coil faces the third magnetic element. The stabilization motor also includes a second sensor, which, along with the third coil, is simultaneously fixed to the base or to the second bracket. The second sensor is positioned to one side of the third coil and is used to detect the displacement of the second bracket. A first plane passes through the second sensor, and a second axis is perpendicular to the first plane, with the first axis lying within the first plane.

[0042] It is understandable that, compared to the scheme of placing the second sensor inside the third coil, in this embodiment, placing the second sensor outside the third coil is beneficial to reducing the excitation interference of the third coil on the second sensor after it is energized, and is beneficial to improving the position detection accuracy of the second sensor, thereby improving the control accuracy.

[0043] Because the second bracket is movably connected to the first bracket, and the first bracket is movably connected to the base, when the second bracket has a displacement relative to the first bracket, and the first bracket also has a displacement relative to the base, if the second sensor is located outside the first plane and fixed to the base, the displacement detected by the second sensor is affected by the movement of the first bracket. In this embodiment, the second sensor passes through the first plane, which reduces the interference from the rotational displacement of the first bracket around the second axis. The second sensor can better detect the displacement of the second bracket within the first plane, which is beneficial to improving the accuracy of the second sensor in detecting the displacement of the second bracket.

[0044] In one possible implementation, the third magnetic element includes a first magnet and a second magnet, which are arranged sequentially along a second direction. The polarity directions of the first magnet and the second magnet are opposite, and both polarity directions intersect with the second direction. Along a first direction, a third coil faces the third magnetic element, and the second sensor and the third coil are arranged opposite each other along the second direction.

[0045] It is understandable that, compared to the second sensor and the third coil being arranged opposite each other along the third direction, in this embodiment, the second sensor and the third coil are spaced apart along the second direction. When the length of the anti-shake motor in the third direction remains unchanged, the third coil in this embodiment can be set to be longer in the third direction, with a longer portion used to cooperate with the third magnetic component to drive the second support to move.

[0046] In one possible implementation, the image stabilization motor further includes a second detection magnet, which is disposed on the side of the second magnet away from the first magnet. The polarity of the second detection magnet is opposite to that of the second magnet. Along the first direction, the second sensor and the second detection magnet are disposed opposite to each other.

[0047] Understandably, the second sensor simultaneously detects the magnetic fields of the second detection magnet and the third magnetic component. The second detection magnet can form a closed loop with the third magnetic component, which extends the magnetic field, allowing the second sensor to detect a stronger magnetic field. This improves the detection accuracy of the second sensor, thereby enhancing the control accuracy of the anti-shake motor.

[0048] In one possible implementation, the third coil includes two sub-coils arranged at intervals along a third direction. Along the third direction, the second sensor is disposed between the two sub-coils. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0049] It is understandable that, along the first direction, the second sensor can be positioned opposite the third magnetic component. The second sensor detects the magnetic field of the third magnetic component to achieve motion displacement detection of the second bracket, thus not increasing the size of the anti-shake horse in the second direction.

[0050] In one possible implementation, the distance L between the second sensor and the third coil can be greater than or equal to 0.01 mm and less than or equal to 10 mm.

[0051] Understandably, the distance between the second sensor and the third coil is within a suitable range. On the one hand, this helps to reduce the excitation interference of the third coil on the second sensor after it is energized. On the other hand, it does not significantly increase the size of the anti-shake motor.

[0052] In one possible implementation, the second support includes a load-bearing portion, a first connecting portion, and a second connecting portion. The load-bearing portion is connected between the first and second connecting portions along a third direction, which is perpendicular to both the first and second directions. The anti-shake motor also includes a first support member and a second support member. Along either the first or second direction, the first support member is rotatably connected between the first support and the first connecting portion, and the second support member is rotatably connected between the first support and the second connecting portion. The first and second support members are spaced apart and arranged opposite to each other along a direction parallel to the second axis.

[0053] Understandably, compared to a sliding connection between the first and second supports, a rolling connection between the first and second supports helps reduce friction between them. The second support connects to the first support on both sides of the load-bearing portion, which facilitates smooth rotation of the second support.

[0054] In one possible implementation, the second support includes a carrier portion for supporting the optical path folding element. The anti-shake motor also includes a first support member and a second support member. Along a second direction, the first support member is rotatably connected between the first support and the carrier portion, and the second support member is rotatably connected between the first support and the carrier portion. The first and second support members are spaced apart and arranged opposite to each other along a direction parallel to the second axis.

[0055] It is understood that the first bracket is movably connected to the load-bearing portion of the second bracket in the second direction. In the third direction, there is no limitation on the structural length of both sides of the load-bearing portion of the second bracket, and the dimension of the second bracket in the third direction can be set to be smaller. The load-bearing portion of the second bracket may or may not have a first connecting portion and a second connecting portion. In this embodiment, the connection scheme of the first and second brackets is advantageous in reducing the length of the second bracket in the third direction.

[0056] In one possible implementation, along the second direction, the back of the bearing portion faces the first support, the bearing portion is provided with a clearance groove, the opening of the clearance groove is located on the back of the bearing portion, and the first support and the second support member are tumblingly connected to the first support within the clearance groove.

[0057] Understandably, the second support is provided with a clearance groove, allowing the connection position between the first and second supports to be closer to the center of gravity of the second support, which is beneficial to the stability of the second support's movement. For example, the first support may include a protrusion. The protrusion of the first support can extend into the clearance groove of the second support. Along the second direction, the first support member and the second support member are rolled between the protrusion of the first support and the load-bearing portion of the second support.

[0058] In one possible implementation, the anti-shake motor further includes a first drive mechanism for driving the second bracket to move relative to the base, and the second bracket driving the first bracket to rotate relative to the base around a first axis.

[0059] It is understood that the first drive mechanism can be used to drive the second bracket to move relative to the base. The first bracket can rotate relative to the base around the first axis through the cooperation of the positioning ball and the positioning groove of the base. This application is not limited to the first drive mechanism directly driving the first bracket to move; the anti-shake motor can also indirectly drive the first bracket to rotate around the first axis through the second bracket.

[0060] In one possible implementation, the first driving mechanism includes a first coil and a first magnetic component. One of the first coil and the first magnetic component is fixed to a base, and the other is fixed to a second bracket. The first coil faces the first magnetic component along a third upward direction. The first driving mechanism can employ a moving coil or moving magnet driving method, which is technologically mature and has low implementation costs.

[0061] In one possible implementation, the second support includes a support portion, a first connecting portion, and a second connecting portion. The support portion is connected between the first and second connecting portions along a third direction, which is perpendicular to both the first and second directions. The support portion is movably connected to the first support. One of the first coil and the first magnetic component is fixed to the base, and the other is fixed to the first connecting portion. The first driving mechanism also includes a second coil and a second magnetic component, one of which is fixed to the base, and the other is fixed to the second connecting portion.

[0062] It is understandable that the first connecting part and the second connecting part can be subjected to force at the same time. When the forces on the first connecting part and the second connecting part are in opposite directions, the force on the first connecting part and the force on the second connecting part simultaneously provide torque to the second bracket, resulting in higher driving efficiency.

[0063] Secondly, embodiments of this application provide a camera module. The camera module includes an optical path folding element and a stabilization motor, with the optical path folding element mounted on the stabilization motor. Light propagates into the stabilization motor through a light inlet in a first direction, and after reflection by the optical path folding element, the light propagates out of the stabilization motor through a light outlet in a second direction.

[0064] Understandably, optical path folding elements can be used to change the direction of light propagation within the camera module. The image stabilization mechanism drives the optical path folding element to rotate around a first axis, thereby achieving optical image stabilization (OIS) and improving the image quality of the camera module. The high control precision of the image stabilization mechanism results in superior image quality for the camera module.

[0065] In one possible implementation, the optical path folding element is a prism or a mirror.

[0066] Thirdly, embodiments of this application provide an electronic device. The electronic device includes a housing and a camera module, with the camera module disposed in the housing. The camera module has better image quality, resulting in a better shooting experience for the electronic device. Attached Figure Description

[0116] For ease of understanding, the English abbreviations and related technical terms used in the embodiments of this application will be explained and described below.

[0117] Heilbeck magnets: By combining magnets of three directions, stronger magnetic thrust is achieved, but the required anti-overturning torque also increases accordingly.

[0118] Optical axis: The direction in which light rays travel through an optical system, referenced to the principal ray at the center of the field of view. For symmetrical transmission systems, it generally coincides with the rotation center line of the optical system. For off-axis and reflective systems, the optical axis may appear as a broken line.

[0119] Focusing: Focusing, also known as light focusing or focusing, is the process of changing the position of the object distance and the camera lens distance through the camera's focusing mechanism to make the subject appear sharp. Digital cameras typically have multiple focusing modes, such as autofocus, manual focus, or multiple focus modes.

[0120] Autofocus: Autofocus is a method that uses the principle of light reflection from an object to receive the reflected light from the camera's sensor (such as a charge-coupled device, CCD), process the data through a computer, and drive the motorized focusing mechanism to achieve the desired focus.

[0121] The embodiments of this application are described below with reference to the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0122] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in this application, "electrical connection" can be understood as components physically contacting and conducting electricity; it can also be understood as a form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A connecting to B or A being connected to B can mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0123] Furthermore, the term "fixed" in this document should be interpreted broadly. For example, "fixed" can mean direct fixing or indirect fixing through an intermediate medium. "Fixed" refers to connections where the relative positional relationship remains unchanged after connection. The directional terms used in the embodiments of this application, such as "upper" and "lower," are merely for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to two or more.

[0124] In the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0125] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0126] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0127] It is understood that the specific embodiments described herein are merely for explaining the relevant application and not for limiting the application. It should also be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0128] Figure 1 is a structural schematic diagram of one embodiment of the electronic device 1000 provided in this application. Figure 2 is a partial cross-sectional schematic diagram of one embodiment of the electronic device 1000 shown in Figure 1 at line AA.

[0129] As shown in Figures 1 and 2, the electronic device 1000 can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, etc., that has a camera module 100. The electronic device 1000 in the embodiment shown in Figure 1 is illustrated using a mobile phone as an example.

[0130] As shown in Figure 1, the electronic device 1000 may include a camera module 100, a housing 200, and a screen 300. The camera module 100 and the screen 300 may be mounted on the housing 200. The camera module 100 may be a rear-facing camera module or a front-facing camera module. It should be noted that Figure 1 and the related accompanying drawings only schematically show some components included in the electronic device 1000; the actual shape, size, position, and structure of these components are not limited by Figure 1 and the accompanying drawings. Furthermore, when the electronic device 1000 is a device of other forms, the electronic device 1000 may not include the screen 300.

[0131] For ease of description, the width direction of electronic device 1000 is defined as the X-axis. The length direction of electronic device 1000 is defined as the Y-axis. The thickness direction of electronic device 1000 is defined as the Z-axis. It can be understood that the coordinate system settings of electronic device 1000 can be flexibly configured according to specific practical needs.

[0132] In this embodiment, the housing 200 may include a frame 210 and a back cover 220. The back cover 220 is fixed to the frame 210. For example, the back cover 220 may be fixedly connected to the frame 210 by adhesive. The back cover 220 may also be integrally formed with the frame 210, that is, the back cover 220 and the frame 210 are a single integral structure.

[0133] Alternatively, the screen 300 can be located on the side of the bezel 210 away from the back cover 220. In this case, the screen 300 and the back cover 220 are located on opposite sides of the bezel 210. The screen 300, bezel 210, and back cover 220 together enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to house components of the electronic device 1000, such as the camera module 100, battery, receiver, or microphone. The screen 300 can be a flat screen or a curved screen.

[0134] For example, the camera module 100 can be a periscope camera module. The camera module 100 can be located inside the electronic device 1000. The camera module 100 can be fixed to the side of the screen 300 facing the rear cover 220. The rear cover 220 can have a light-transmitting hole 2201. The shape of the light-transmitting hole 2201 is not limited to the circle shown in Figure 1. The light-transmitting hole 2201 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from the exterior of the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 2201. The camera module 100 can capture the ambient light entering the interior of the electronic device 1000.

[0135] Figure 3 is a structural schematic diagram of the image stabilization component 10 of the camera module 100 shown in Figure 2 in some embodiments. Figure 4 is an exploded structural schematic diagram of the image stabilization component 10 shown in Figure 3 in some embodiments.

[0136] As shown in Figures 2 to 4, the camera module 100 may include a stabilization component 10, a lens assembly 20, and an image sensor 30 arranged sequentially from the object side to the image side. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through a light-transmitting hole, then pass sequentially through the stabilization component 10 and the lens assembly 20, and finally be imaged onto the image sensor 30. For example, the stabilization component 10, the lens assembly 20, and the image sensor 30 may be arranged sequentially along the X-axis.

[0137] In some embodiments, one or more reflective lenses / prisms can be additionally disposed between the image stabilization component 10 and the image sensor 30 to change the light propagation path between the image stabilization component 10 and the image sensor 30. This allows light emitted from the image stabilization component 10 to undergo one or more reflections before finally entering the image sensor 30. This lengthens the overall light path of the camera module 100, which helps to reduce the overall module length of the camera module 100 and saves internal space in the electronic device 1000.

[0138] In some embodiments, the image stabilization component 10 may include an image stabilization motor 1 and a first optical element 2, the first optical element 2 being mounted on the image stabilization motor 1. The first optical element 2 may include an optical path folding element 24, and the first optical element 2 can be used to change the propagation direction of light within the camera module. The image stabilization motor 1 can drive the first optical element 2 to rotate around a first direction and / or a third direction to achieve optical image stabilization (OIS) of the camera module 100, improving the image quality of the camera module 100. The third direction is perpendicular to the first direction and perpendicular to the second direction. Exemplarily, the image stabilization motor 1 can drive the optical path folding element 24 to rotate around a first axis R1 and / or a second axis R2. Wherein, the first axis R1 is parallel to the second direction, and the second axis R2 is parallel to the third direction.

[0139] For example, the image stabilization motor 1 may have a light inlet 101 and a light outlet 102. Light can propagate into the image stabilization motor 1 through the light inlet 101 in the first direction Z, and after being reflected by the first optical element 2, the light can propagate out of the image stabilization motor 1 in the second direction X.

[0140] Figure 5 is an exploded structural diagram of the first optical element 2 of the image stabilization assembly 10 shown in Figure 3 in some embodiments. Figure 6 is a partial cross-sectional view of the first optical element 2 shown in Figure 4 at line BB in one embodiment.

[0141] As shown in Figures 5 and 6, the first optical element 2 may include an incident surface 21, a reflecting surface 22, and an exiting surface 23. Light can enter the interior of the first optical element 2 through the incident surface 21, be reflected by the reflecting surface 22, and then exit through the exiting surface 23. The optical axis T1 of the first optical element 2 may be perpendicular to the incident surface 21. The optical axis T2 of the first optical element 2 may be perpendicular to the exiting surface 23. In this embodiment, the optical axis T1 of the first optical element 2 may be parallel to the Z-axis direction, and the optical axis T2 may be parallel to the X-axis direction. The first optical element 2 may include an optical path folding element 24 and a first lens 25. The first lens 25 may be fixed to the light-incident side of the optical path folding element 24. In this case, the incident surface of the first lens 25 can constitute the incident surface 21 of the first optical element 2.

[0142] In some embodiments, the first lens 25 and the optical path folding element 24 can be integrally formed structural components.

[0143] For example, the optical path folding element 24 can be a reflecting prism. The cross-section of the optical path folding element 24 can be triangular. The optical path folding element 24 can include a first surface 241, a second surface 242, and a third surface 243. The first surface 241 and the third surface 243 can be perpendicular to each other. The second surface 242 can be connected between the first surface 241 and the third surface 243. The first surface 241 can be perpendicular to the input optical axis T1. The third surface 243 can be perpendicular to the output optical axis T2. Both the first surface 241 and the third surface 243 can be transmissive surfaces. The second surface 242 can be a reflective surface 22. Thus, light can enter the interior of the optical path folding element 24 through the first surface 241, be reflected by the second surface 242, and exit through the third surface 243. At this time, the second surface 242 of the optical path folding element 24 can constitute the reflective surface 22 of the first optical element 2. The third surface 243 of the optical path folding element 24 can constitute the output surface 23 of the first optical element 2.

[0144] In other embodiments, the optical path folding element 24 may also be a reflector. This application does not limit the specific form of the optical path folding element 24.

[0145] For example, the first lens 25 can be located on the light-incident side of the optical path folding element 24. The first lens 25 can be fixedly connected to the first surface of the optical path folding element 24 by means of bonding or other methods. The first lens 25 can be a lens with positive optical power. In this way, the first lens 25 can have a light-gathering effect, allowing as much external light as possible to enter the optical path folding element 24, thereby increasing the light intake of the entire first optical element 2 and improving the light intake of subsequent focusing components. In other embodiments, the first lens 25 and the optical path folding element 24 can also be fixedly connected by other structural components.

[0146] In some embodiments, the first optical element 2 may further include a second lens 26. The second lens 26 may be a lens with negative optical power. The second lens 26 may be located on the light-emitting side of the optical path folding element 24. The second lens 26 may be fixedly connected to the third surface of the optical path folding element 24 by means of bonding or other methods. In this way, the second lens 26 has a diffusing effect, which can diffuse as much light emitted from the optical path folding element 24 as possible, thereby increasing the light output of the entire first optical element 2 and improving the light intake of the subsequent focusing assembly. At this time, the exit surface of the second lens 26 may constitute the exit surface 23 of the first optical element 2. In other embodiments, the second lens 26 and the optical path folding element 24 may also be fixedly connected by other structural components.

[0147] In some embodiments, the second lens 26 and the optical path folding element 24 can be integrally formed structural components.

[0148] In some embodiments, the first optical element 2 may not include the first lens 25, but only the optical path folding element 24.

[0149] As shown in Figure 2, the lens assembly 20 can be a lens group. The lens group may include at least one lens. The lens assembly 20 can be positioned opposite to the light exit aperture 102.

[0150] For example, the image sensor 30 is a semiconductor chip, also known as a photosensitive chip. The surface of the image sensor 30 contains hundreds of thousands to millions of photodiodes, which generate electrical charges when illuminated. The image sensor 30 utilizes the photoelectric conversion function of optoelectronic devices to convert the light image on its photosensitive surface into an electrical signal proportional to the light image. The photosensitive surface of the image sensor 30 can be positioned facing the lens assembly 20. The image sensor 30 can be a charge-coupled device, a complementary metal-oxide-semiconductor, a phototransistor, or a thin-film transistor, etc. In other embodiments, the image sensor 30 can also be a component with other structures.

[0151] For example, the image sensor 30 can be located on the image side of the lens assembly 20. Light rays propagating from the light exit aperture 102 can pass through the lens assembly 20 and reach the image sensor 30, thereby achieving image formation.

[0152] In other embodiments, the camera module 100 may also include a focusing motor (not shown). The lens assembly 20 may be mounted on the focusing motor. The focusing motor can control the movement of the lens assembly 20 along the optical axis to achieve autofocus (AF).

[0153] It is understandable that compared to a camera module 100 that additionally sets a reflecting prism between the lens assembly 20 and the image sensor 30 and controls the displacement of the image sensor 30 to achieve optical image stabilization, the module size is relatively large. In this embodiment, the camera module 100 achieves optical image stabilization by setting an image stabilization motor to drive the first optical element 2 to rotate around the first axis R1 and / or drive the first optical element 2 to rotate around the second axis R2. This eliminates the need for an additional prism between the focusing assembly and the image sensor 30, resulting in a smaller module size and facilitating miniaturization of the camera module 100. In this embodiment, the first axis R1 is parallel to the output light axis T2 (i.e., parallel to the X-axis direction in this embodiment). The second axis R2 is perpendicular to both the input light axis T1 and the output light axis T2 (i.e., parallel to the Y-axis direction in this embodiment). The camera module 100 achieves image stabilization by controlling the rotation of the first optical element 2 around the first axis R1 and / or the second axis R2 using the image stabilization motor, resulting in higher image stabilization accuracy and better image quality.

[0154] The above text describes the structure of the electronic device 1000, the camera module 100, and the first optical element 2 of the camera module 100. The following text will describe the structure of the image stabilization motor in the camera module 100 in detail with reference to the relevant figures.

[0155] Figure 7 is a structural schematic diagram of the anti-shake motor of the anti-shake component 10 shown in Figure 4 in some embodiments. Figure 8 is an exploded structural schematic diagram of the anti-shake motor shown in Figure 7 in some embodiments. It should be understood that in this embodiment, the width direction of the anti-shake motor, which is also the width direction of the electronic device 1000, is the X-axis direction. The length direction of the anti-shake motor, which is also the length direction of the electronic device 1000, is the Y-axis direction. The thickness direction of the anti-shake motor, which is also the thickness direction of the electronic device 1000, is the Z-axis direction. In other embodiments, the coordinate system setting of the anti-shake motor can be flexibly set according to specific actual needs.

[0156] As shown in Figures 7 and 8, the anti-shake motor 1 includes a base 11, a first bracket 12, a first drive mechanism 13, a positioning ball 14, a first support member 151, a second support member 152, a second bracket 16, a second drive mechanism 17, a circuit board assembly 18, a first support member 153, a second support member 154, a first magnetic member 155, a second magnetic member 156, and a housing 19. The first bracket 12 is movably connected to the base 11. The first bracket 12 can rotate relative to the base 11 about a first axis R1. The second bracket 16 is movably connected to the first bracket 12. The second bracket 16 can rotate relative to the base 11 about a second axis R2. The first drive mechanism 13 drives the first bracket 12 to rotate about the first axis R1. The second drive mechanism 17 drives the second bracket 16 to rotate about the second axis R2. The positioning ball 14, the first support member 151, and the second support member 152 are movably connected between the first bracket 12 and the base 11. The first support member 153 and the second support member 154 are movably connected between the second bracket 16 and the first bracket 12. The first magnetic member 155 is used to press the first bracket 12 onto the base 11. The second magnetic member 156 is used to press the second bracket 16 onto the first bracket 12. The following describes several embodiments of the operation of the various components of the anti-shake motor 1 with reference to the accompanying drawings.

[0157] In some embodiments, the first driving mechanism 13 can employ a moving coil or moving magnet driving method, which is technologically mature and has low implementation cost. For example, the first driving mechanism 13 may include a first coil 131, a first magnetic element 132, a second coil 133, and a second magnetic element 134. In other embodiments, the first driving mechanism 13 may also include more or fewer structures; for example, the first driving mechanism 13 may also include a magnetic conductor (not shown in the figures).

[0158] It is understood that the number of first coils 131 is not limited to the one shown in Figure 8, and the number of first magnetic elements 132 is not limited to the one shown in Figure 8. In other embodiments, the number of first coils 131 can be multiple, the number of first magnetic elements 132 can be multiple, and multiple first coils 131 and multiple first magnetic elements 132 can be arranged in a one-to-one correspondence.

[0159] It is understood that the number of second coils 133 is not limited to the one shown in Figure 8, and the number of second magnetic elements 134 is not limited to the one shown in Figure 5. In other embodiments, the number of second coils 133 can be multiple, the number of second magnetic elements 134 can be multiple, and multiple second coils 133 and multiple second magnetic elements 134 can be arranged in a one-to-one correspondence.

[0160] In other embodiments, the first drive mechanism 13 may also omit the second coil 133 and the second magnetic element 134.

[0161] In other embodiments, the first drive mechanism 13 may also employ other forms of drive structures, such as piezoelectric ceramic drives or shape memory alloy drives. This application does not specifically limit the application to these methods.

[0162] In some embodiments, the second drive mechanism 17 can employ a moving coil or moving magnet drive method, which is technologically mature and has low implementation cost. For example, the second drive mechanism 17 may include a third coil 171 and a third magnetic element 172. In other embodiments, the second drive mechanism 17 may also include more or fewer structures; for example, the second drive mechanism 17 may also include a magnetic conductor.

[0163] It is understood that the number of third coils 171 is not limited to the one shown in Figure 8, and the number of third magnetic elements 172 is not limited to the one shown in Figure 8. In other embodiments, the number of third coils 171 can be multiple, the number of third magnetic elements 172 can be multiple, and multiple third coils 171 and multiple third magnetic elements 172 can be arranged in a one-to-one correspondence.

[0164] In other embodiments, the second drive mechanism 17 may also employ other types of drive structures, such as piezoelectric ceramic drives or shape memory alloy drives. This application does not specifically limit the application to these methods.

[0165] Figure 9 is a structural schematic diagram of the base 11 shown in Figure 5 in one embodiment. Figure 10 is a structural schematic diagram of the base 11 shown in Figure 9 from another angle.

[0166] As shown in Figures 9 and 10, the base 11 may include a base plate 111, a first side plate 112, a second side plate 113, and a back plate 114. Exemplarily, the first side plate 112, the second side plate 113, and the back plate 114 may be located on the same side of the base plate 111 and fixedly connected to it. The first side plate 112 and the second side plate 113 may be arranged opposite each other and spaced apart, and may be arranged along a third direction. The back plate 114 may be located on the same side of the first side plate 112 and the second side plate 113 and connected between them. The base plate 111, the first side plate 112, the second side plate 113, and the back plate 114 may enclose an installation space, which can be used to accommodate structural components such as the second bracket 16 and the first bracket 12. In other embodiments, the base 11 may also employ other structures.

[0167] It is understood that, for ease of describing the specific structure and shape of the base 11, this embodiment describes the base 11 in four parts. However, this does not affect the fact that the base 11 can be a one-piece molded structure, that is, the base plate 111, the first side plate 112, the second side plate 113, and the back plate 114 can be integrally molded. In other embodiments, the base 11 can also be formed by different independent structural components through an assembly process. For example, the first side plate 112 and the second side plate 113 of the base 11 can be two independent structural components, and are fixedly connected to the base plate 111 by means of adhesive bonding, welding, etc.

[0168] In some embodiments, the base 11 may be provided with a positioning groove 110. The positioning groove 110 can be used to accommodate positioning balls. The positioning groove 110 may include three limiting surfaces 1101, which form the three sides of a triangular pyramid. Exemplarily, the positioning groove 110 may be located on the back plate 114 of the base 11, and the opening of the positioning groove 110 may face the installation space.

[0169] In some embodiments, the base plate 111 may be provided with a first clearance hole 1111. The first clearance hole 1111 can penetrate the base plate 111 in a first direction Z. The second side plate 113 may be provided with a second clearance hole 1131. The second clearance hole 1131 can penetrate the second side plate 113 in a third direction Y. The first clearance hole 1111 can be used to accommodate a portion of the second drive mechanism. The second clearance hole 1131 can be used to accommodate a portion of the first drive mechanism.

[0170] For example, the first side plate 112 may be provided with a first mounting groove 1121. The opening of the first mounting groove 1121 may face the second side plate 113. The first mounting groove 1121 may be used to accommodate part of the first drive mechanism.

[0171] Figure 11 is an exploded structural diagram of the base 11 shown in Figure 9 in one embodiment. Figure 12 is a partial cross-sectional view of the base 11 shown in Figure 9 at line CC in one embodiment.

[0172] As shown in Figures 11 and 12, the backplate 114 may include a backplate body 1141 and a metal insert 1142. The metal insert 1142 may be embedded in the backplate body 1141, and partially exposed above it. Exemplarily, the metal insert 1142 may be embedded in the backplate body 1141 using an insert injection molding process. The backplate body 1141 may be made of materials such as plastic. Exemplarily, the backplate body 1141 may be integrally formed with the base plate 111, the first side plate 112, and the second side plate 113 using an injection molding process. The metal insert 1142 may be made of metal materials such as stainless steel. The hardness of the metal insert 1142 is greater than the hardness of the backplate body 1141. The metal insert 1142 may be used to provide better strength for the support of the first bracket 12.

[0173] For example, the backplate body 1141 may be provided with a first support groove 1143, a second support groove 1144, and a second mounting groove 1145. When the metal insert 1142 is embedded in the backplate body 1141, a portion of the metal insert 1142 may protrude from the bottom of the first support groove 1143 and a portion may protrude from the bottom of the second support groove 1144. A portion of the metal insert 1142 may be located within the second mounting groove 1145 of the backplate body 1141, recessed towards the backplate body 1141 to form a positioning groove 110. The opening of the positioning groove 110 faces away from the backplate body 1141. The second mounting groove 1145 is used to provide a recessed space for the metal insert 1142.

[0174] In other embodiments, the metal insert 1142 may also be fixedly connected to the back plate body 1141 by adhesive or welding.

[0175] Figure 13 is a schematic diagram of the assembly structure of the circuit board assembly 18, the third coil 171, and the second coil 133 shown in Figure 8 in one embodiment.

[0176] As shown in Figure 13, the circuit board assembly 18 can be generally L-shaped. Exemplarily, the circuit board assembly 18 may include a flexible circuit board 181 and a reinforcing plate 182. The reinforcing plate 182 can be used to reinforce the circuit board assembly 18, giving it better load-bearing capacity.

[0177] Exemplarily, the flexible circuit board 181 may include a first fixing portion 1811 and a second fixing portion 1812. The second fixing portion 1812 may be bent relative to the first fixing portion 1811. It is understood that, for ease of description of the basic structure and shape of the circuit board, the flexible circuit board 181 is described in two parts in this embodiment, but this does not affect the fact that the flexible circuit board 181 can be a one-piece structure, that is, the second fixing portion 1812 and the first fixing portion 1811 can be integrally formed. In other embodiments, the flexible circuit board 181 may also be formed from different independent structural components through an assembly process. For example, the first fixing portion 1811 of the flexible circuit board 181 may be an independent structural component and fixedly connected to the second fixing portion 1812 by means of adhesive bonding, welding, etc. In other embodiments, the flexible circuit board 181 may also adopt other structures.

[0178] For example, there can be two reinforcing plates 182, one of which is fixedly connected to the first fixing part 1811, and the other is fixedly connected to the second fixing part 1812.

[0179] For example, the third coil 171 can be fixedly connected to the first fixing part 1811 and electrically connected to the first fixing part 1811. The second coil 133 can be fixedly connected to the second fixing part 1812 and electrically connected to the second fixing part 1812.

[0180] Exemplarily, the second drive mechanism 17 may further include a second sensor 173. The second sensor 173 is used to detect the displacement of the second bracket 16 rotating about the second axis R2. The second sensor 173 may be fixedly connected to the first fixing part 1811 and electrically connected to the first fixing part 1811. The second sensor 173 may be spaced apart from the third coil 171. Exemplarily, the second sensor 173 may be a Hall sensor.

[0181] In other embodiments, the circuit board assembly 18 may not have the reinforcing plate 182. The circuit board assembly 18 may be a rigid circuit board or a rigid-flex circuit board.

[0182] Figure 14 is a partial structural schematic diagram of one embodiment of the anti-shake motor 1 shown in Figure 7. Figure 15 is a structural schematic diagram of the anti-shake motor 1 shown in Figure 14 from another angle.

[0183] As shown in Figures 14 and 15, the circuit board assembly 18 can be fixedly connected to the base 11. Exemplarily, the first fixing part 1811 of the circuit board assembly 18 can be fixedly connected to the bottom plate 111 of the base 11, and the second fixing part 1812 of the circuit board assembly 18 can be fixedly connected to the second side plate 113.

Exemplarily, at least a portion of the third coil 171 can be located within the first clearance hole 1111 of the base plate 111. It is understood that the third coil 171 can utilize the thickness of the base plate 111 of the base 11, which helps to reduce the thickness of the anti-shake motor 1 in the first direction Z, thereby facilitating the miniaturization of the anti-shake motor 1. In other embodiments, the third coil 171 can also be directly fixedly connected to the base 11 and electrically connected to the first fixing part 1811 of the circuit board via a wiring (not shown in the figures) or other structural components.

[0185] In one embodiment, the second sensor 173 can be fixedly connected to the base plate 111 of the base 11 via the first fixing part 1811. Exemplarily, at least a portion of the second sensor 173 can be located within the first clearance hole 1111 of the base plate 111.

Exemplarily, at least a portion of the first coil 131 may be located in a first mounting groove 1121 of a first side plate 112 of the base 11. The first coil 131 may be electrically connected to the circuit board assembly 18 via wiring or other structural components. Exemplarily, conductive wiring may be embedded within the base 11, connecting the first coil 131 and the circuit board.

[0187] In one embodiment, the second coil 133 can be fixedly connected to the base 11 via the second fixing part 1812. Exemplarily, at least a portion of the second coil 133 can be located within the second clearance hole 1131 of the second side plate 113. In other embodiments, the second coil 133 can also be directly fixedly connected to the base 11 and electrically connected to the first fixing part 1811 of the circuit board via structural components such as wiring (not shown in the figures).

[0188] In one embodiment, the image stabilization motor may further include a first sensor 135. The first sensor 135 can be used to detect the displacement of the first bracket rotating about a first axis R51. The first sensor 135 can be fixedly connected to the base 11. Exemplarily, the first sensor 135 can be fixedly connected to the back plate 114 of the base 11. The first sensor 135 can be a Hall sensor. In other embodiments, the first sensor 135 can be other types of sensors.

[0189] In some embodiments, the first sensor 135 can be electrically connected to the circuit board assembly 18 via an electrically connected structure such as wiring (not shown). Exemplarily, the wiring can be embedded in the base 11, and the wiring connects the first sensor 135 and the circuit board.

[0190] Figure 16 is a structural schematic diagram of one embodiment of the first support 12 shown in Figure 8. Figure 17 is a structural schematic diagram of the first support 12 shown in Figure 16 from another angle.

[0191] As shown in Figures 16 and 17, the first support 12 includes a first arm 121, a second arm 122, and a connecting arm 123. Exemplarily, the first arm 121 and the second arm 122 can be arranged opposite to each other and spaced apart, and the connecting arm 123 can be fixedly connected between the first arm 121 and the second arm 122. The arrangement direction of the first arm 121 and the second arm 122 can be parallel to a third direction Y.

[0192] It is understood that, for ease of describing the basic structure and shape of the first support 12, this embodiment describes the first support 12 in three parts. However, this does not affect the fact that the first support 12 can be a one-piece molded structure, that is, the first arm 121, the second arm 122, and the connecting arm 123 can be integrally molded. In other embodiments, the first support 12 can also be formed by different independent structural components through an assembly process. For example, the first arm 121 and the second arm 122 of the first support 12 can be independent structural components and are fixedly connected to the connecting arm 123 by means of adhesive bonding, welding, etc.

[0193] For example, the connecting arm 123 may include a first surface 1231 and a second surface 1232. The first surface 1231 and the second surface 1232 may be arranged opposite to each other along a second direction. The first arm 121 and the second arm 122 may be fixedly connected to the first surface 1231 of the connecting arm 123.

[0194] For example, the first arm 121 may be provided with a second groove 1211. The opening of the second groove 1211 may face away from the second arm 122. The second groove 1211 may be used to accommodate part of the first drive mechanism.

[0195] Exemplarily, the first support arm 121 may be provided with a first limiting groove 1212. The opening of the first limiting groove 1212 may be located on the top surface of the first support arm 121. In some embodiments, the first limiting groove 1212 may be a conical groove. Exemplarily, the first limiting groove 1212 may include three second limiting surfaces 1213, which are arranged in a generally triangular pyramid shape, that is, the three second limiting surfaces 1213 constitute the three sides of a triangular pyramid. The first limiting groove 1212 may be used to accommodate part of the first support member.

[0196] For example, the second arm 122 may be provided with a third groove 1221. The opening of the third groove 1221 may face away from the first arm 121. The third groove 1221 may be used to accommodate part of the first drive mechanism.

[0197] For example, the second support arm 122 may be provided with a second limiting groove 1222. The opening of the second limiting groove 1222 may be located on the top surface of the second support arm 122. The second limiting groove may be used to accommodate part of the second support member.

[0198] In some embodiments, the connecting arm 123 may be provided with a fixing groove 1233, a first rolling groove 1234, and a second rolling groove 1235. The openings of the fixing groove 1233, the first rolling groove 1234, and the second rolling groove 1235 may all be located on the second surface 1232 of the connecting arm 123. The fixing groove 1233, the first rolling groove 1234, and the second rolling groove 1235 are spaced apart. Exemplarily, the first rolling groove 1234 and the second rolling groove 1235 may be arranged spaced apart along a third direction upward. The fixing groove 1233 may be used to accommodate a portion of the positioning ball. The first rolling groove 1234 may be used to accommodate a portion of the first bearing member. The second rolling groove 1235 may be used to accommodate a portion of the second bearing member.

[0199] For example, the connecting arm 123 may be provided with a third mounting groove 1236 and a fourth mounting groove 1237. The openings of the third mounting groove 1236 and the fourth mounting groove 1237 may both be located on the second surface 1232 of the connecting arm 123. The fixing groove 1233, the first rolling groove 1234, the second rolling groove 1235, the third mounting groove 1236, and the fourth mounting groove 1237 are spaced apart. The third mounting groove 1236 may be used to accommodate a first magnetic attractant. The fourth mounting groove 1237 may be used to accommodate a first detection magnet.

[0200] Figure 18 is a schematic diagram of the assembly structure of the first support 12 and the first magnetic element 132 shown in Figure 7 in one embodiment. Figure 19 is a schematic diagram of the structure of the first support 12, the second magnetic element 134, the positioning ball 14, the first support 151, the second support 152, the first magnetic attracting element 155, and the first detection magnet 157 shown in Figure 7 in one embodiment.

[0201] As shown in Figures 18 and 19, the first magnetic element 132 can be fixedly connected to the first bracket 12. Exemplarily, the first magnetic element 132 can be fixedly connected to the second groove 1211 of the first arm 121 of the first bracket 12. For example, the first magnetic element 132 can employ a Hellbeck magnet scheme. That is, the first magnetic element 132 can be composed of three magnets, including a first magnet 1321, a second magnet 1322, and a third magnet 1323. The first magnet 1321, the second magnet 1322, and the third magnet 1323 of the first magnetic element 132 can be arranged along a first direction. The polarity directions of the first magnet 1321, the second magnet 1322, and the third magnet 1323 of the first magnetic element 132 are all different. The polarity direction of the first magnet 1721 of the first magnetic element 132 and the polarity direction of the third magnet 1723 of the first magnetic element 132 are at an angle to the first direction. For example, the polarity direction of the first magnet 1721 of the first magnetic element 132 and the polarity direction of the third magnet 1723 of the first magnetic element 132 are opposite.

[0202] In one embodiment, the second magnetic element 134 can be fixedly connected to the first bracket 12. Exemplarily, the second magnetic element 134 can be fixedly connected to the second arm 122 of the first bracket 12 and located within the third groove 1221. For example, the second magnetic element 134 can employ a Heilbeck magnet scheme. The second magnetic element 134 can be configured with reference to the first magnetic element 132.

[0203] In other embodiments, the first magnetic element 132 and the second magnetic element 134 may also adopt a dual magnet scheme or a single magnet scheme, and this application does not impose any restrictions.

[0204] In one embodiment, the positioning ball 14 may be disposed on the first bracket 12. Exemplarily, the positioning ball 14 may be fixedly connected to the connecting arm 123 of the first bracket 12 and located within the fixing groove 1233. Exemplarily, the positioning ball 14 may be made of ceramic or metal. In other embodiments, the positioning ball 14 may also be rotatably connected within the fixing groove 1233.

[0205] In one embodiment, the first support member 151 may be disposed on the first bracket 12. Exemplarily, the first support member 151 may be partially located within the first rolling groove 1234. Exemplarily, the first support member 151 may be made of ceramic or metal.

[0206] In one embodiment, the second support member 152 may be disposed on the first bracket 12. Exemplarily, the second support member 152 may be partially located within the second rolling groove 1235. Exemplarily, the material of the second support member 152 may be ceramic or metal.

[0207] In one embodiment, the first magnetic member 155 can be fixedly connected to the first bracket 12. For example, the first magnetic member 155 can be fixedly connected to the connecting arm 123 of the first bracket 12 and located in the third mounting groove 1236.

[0208] For example, the anti-shake motor 1 further includes a first detection magnet 157. The first detection magnet 157 can be fixedly connected to the first bracket 12. The first detection magnet 157 can be used to detect the rotational displacement of the first bracket 12. In one embodiment, the first detection magnet 157 can be fixedly connected to the connecting arm 123 of the first bracket 12 and located in the fourth mounting groove 1237.

[0209] Figure 20 is a partial structural schematic diagram of the anti-shake motor 1 shown in Figure 7 in one embodiment. Figure 21A is a partial cross-sectional schematic diagram of the anti-shake motor 1 shown in Figure 20 at the DD line in one embodiment. Figure 21B is a partial cross-sectional schematic diagram of the anti-shake motor 1 shown in Figure 20 at the EE line in one embodiment.

[0210] As shown in Figures 20 to 21B, the first bracket 12 is movably connected to the base 11. The first bracket 12 can be located inside the base 11. Exemplarily, along a third upward direction, the first arm 121 of the first bracket 12 can be disposed opposite to the first side plate 112 of the base 11. The second arm 122 of the first bracket 12 can be disposed opposite to the second side plate 113 of the base 11. Along the direction of the first axis R1, the connecting arm 123 of the first bracket 12 can be disposed opposite to the back plate 114 of the base 11.

[0211] In one embodiment, the first bracket 12 can be movably connected to the base 11 via a positioning ball 14, a first support member 151, and a second support member 152. For example, the positioning ball 14 can be movably connected between the first bracket 12 and the base 11.

[0212] In one embodiment, the positioning ball 14 is movably connected to the back plate 114 of the base 11. Exemplarily, the positioning ball 14 is movably connected within the positioning groove 110 of the back plate 114. The groove surface of the positioning groove 110 includes three limiting surfaces 1101, which form the three sides of a triangular pyramid. The positioning ball 14 and the positioning groove 110 are arranged along a second direction. The positioning ball 14 is movably connected within the positioning groove 110 and simultaneously contacts the three limiting surfaces 1101. The first shaft R1 passes through the center of the space enclosed by the three limiting surfaces 1101. It is understood that this application achieves the positioning of the first shaft R1 through the cooperation of the positioning ball 14 and the positioning groove 110, allowing the first bracket 12 to rotate around the first shaft R1 when movably connected to the base 11. The positioning ball 14 and positioning groove 110 in this application achieve positioning through point-to-surface contact. Compared to the surface-to-surface contact method, the point-to-surface contact positioning method in this application is less affected by the installation and manufacturing accuracy of the structural components, and is easier to assemble. Furthermore, the point-to-surface contact results in a small contact area, reducing friction between the first bracket 12 and the base 11. This reduces the likelihood of jamming when the first bracket 12 moves relative to the base 11, and allows for higher control accuracy of the anti-shake motor 1. When the anti-shake motor 1 is used in the camera module 100, the imaging quality of the camera module 100 is better. In addition, when the positioning ball 14 is connected within the positioning groove 110, there are always three contact points at any given time, providing better limiting and support for the positioning ball 14.

[0213] It is understood that adjacent limiting surfaces 1101 can be directly connected or indirectly connected. The positioning groove 110 can be a conical groove, a rectangular groove, or other polygonal groove. This application does not impose any restrictions.

[0214] Exemplarily, the metal insert 1142 may be recessed in a direction away from the first support 12 to form a positioning groove 110. The positioning ball 14 may roll over the metal insert 1142 of the back plate 114. This helps reduce the kinetic friction between the positioning ball 14 and the metal insert 1142 of the back plate 114, thereby helping to reduce the kinetic friction between the base 11 and the first support 12. Furthermore, the metal insert 1142 is made of metal, which has a lower coefficient of friction than the positioning ball 14 directly rubbing against a plastic material. Rolling the positioning ball 14 over the metal insert 1142 further helps to reduce the kinetic friction between the first support 12 and the base 11. In other embodiments, the positioning ball 14 may slide over the metal insert 1142 of the back plate 114.

[0215] In one embodiment, along the second direction, the gap D1 between the first bracket 12 and the base 11, the radius R of the positioning ball 14, and the depth D2 of the positioning ball 14 in the positioning groove 110 satisfy the following relationship: 0 < D1 < (2R - D2). In this way, while satisfying the reliability and motion stability of the positioning ball 14 in the positioning groove 110, the base 11 and the first bracket 12 are free from motion interference.

[0216] In one embodiment, the radius R of the positioning ball 14 and the depth D2 of the positioning ball 14 in the positioning groove 110 satisfy the following relationship: 0.01R≤D2≤0.9R. In this way, the contact area between the positioning ball 14 and the positioning groove 110 can be within a suitable range, ensuring that the positioning ball 14 can be stably placed in the positioning groove 110 during movement and is not easily dislodged during the process of contact.

[0217] In one embodiment, the included angles between the three limiting surfaces 1101 and the first shaft R1 are equal. For example, two adjacent limiting surfaces 1101 are arranged at a 60° angle, and the limiting surfaces 1101 and the first shaft R1 are also arranged at a 60° angle. This results in a more regular shape for the positioning groove 110, reducing design and manufacturing complexity.

[0218] In one embodiment, the positioning ball 14 is fixedly connected to the first bracket 12. In this way, the connection strength between the positioning ball 14 and the first bracket 12 is better, the position of the positioning ball 14 relative to the first bracket 12 is not easily moved, the interference of the positioning ball 14 is smaller when the anti-shake motor 1 detects the position of the first bracket 12 relative to the base 11, and the control accuracy of the anti-shake motor 1 is better.

[0219] Figure 22 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 20 at the FF line.

[0220] As shown in Figures 21B and 22, the first support member 151 can be movably connected between the base 11 and the first support 12. The first support member 151 can be used for the support connection between the base 11 and the first support 12. By providing the first support member 151, the connection area between the base 11 and the first support 12 can be increased, which is beneficial for a stable connection between the first support 12 and the base 11. For example, the first support member 151 can be rolled between the base 11 and the first support 12. Thus, compared to the first support member 151 sliding between the base 11 and the first support 12, the first support member 151 rolling between the base 11 and the first support 12 helps reduce the friction between the first support member 151 and the base 11 and the first support 12, thereby reducing the kinetic friction between the first support 12 and the base 11.

[0221] For example, the first support member 151 can be rolled between the metal insert 1142 of the back plate 114 of the base 11 and the connecting arm 123 of the first bracket 12. In this way, the first support member 151 can be rolled to the metal insert 1142, and the coefficient of friction of the metal insert 1142 is smaller than that of plastic, which helps to reduce the kinematic friction between the first support member 151 and the back plate 114, thereby helping to reduce the kinematic friction between the first bracket 12 and the base 11.

[0222] In one embodiment, the first support member 151 is rotatably connected to the first support groove 1143 of the back plate 114 of the base 11 and the first rolling groove 1234 of the connecting arm 123 of the first bracket 12. A portion of the first support member 151 is located in the first rolling groove 1234 and a portion is located in the first support groove 1143.

[0223] It is understood that the first support groove 1143 and the first rolling groove 1234 can be used to limit the first bearing member 151. When the first bearing member 151 is movably connected between the base 11 and the first bracket 12, the first support groove 1143 and the first rolling groove 1234 can be used to prevent the first bearing member 151 from detaching from the base 11 or the first bracket 12. Those skilled in the art can selectively set one or more of the first support groove 1143 and the first rolling groove 1234 according to needs, and this application does not impose any restrictions. When only one of the first support groove 1143 and the first rolling groove 1234 is selected for limiting the first bearing member 151, the other can adopt a planar structure for contact.

[0224] In some embodiments, the cross-sectional area of ​​the first support groove 1143 is larger than the cross-sectional area of ​​the first support member 151. The second direction is perpendicular to the plane containing the cross-sectional area of ​​the first support groove 1143. In this way, there can be a larger space within the first support groove 1143 to support the rolling of the first support member 151.

[0225] In some embodiments, the cross-sectional area of ​​the first rolling groove 1234 is larger than the cross-sectional area of ​​the first support member 151, and the second direction is perpendicular to the plane containing the cross-sectional area of ​​the first rolling groove 1234. In this way, there can be a larger space within the first rolling groove 1234 for the first support member 151 to roll.

[0226] For example, the first support member 151 may be a ball or a roller, etc. This application does not limit the shape of the first support member 151. When the first support member 151 is a ball, compared with the scheme where the first support member 151 is a roller, the connection area between the ball and the base 11 and the first support 12 can be smaller than that of the roller, which is beneficial to reduce the kinematic friction between the first support member 151 and the base 11 and the first support 12.

[0227] In some embodiments, the first bearing member 151 may include one or more balls. When there are multiple balls, the bearing area between the first bearing member 151 and the base 11 can be larger, and the bearing area between the first support 12 and the base 11 can also be larger, which helps to reduce the risk of reliability issues in the bearing area between the first support 12 and the base 11. For example, the first bearing member 151 may include three balls.

[0228] It is understood that when there are multiple first bearing members 151, the shape and size of the multiple first bearing members 151 can be set to be the same or different, and this application does not impose any restrictions.

[0229] In some embodiments, the anti-shake motor 1 may further include a lubricating medium. The lubricating medium is connected between the first support member 151, the base 11, and the first bracket 12. Exemplarily, the lubricating medium may be disposed within the first support groove 1143 and the first rolling groove 1234. This can further reduce the kinematic friction between the first bracket 12 and the base 11. Exemplarily, the friction medium may be lubricating oil or grease.

[0230] In other embodiments, the first support member 151 may also be fixedly connected to the first bracket 12 and slidably connected to the base 11. Alternatively, the first support member 151 may be fixedly connected to the base 11 and slidably connected to the first bracket 12.

[0231] For example, the second support member 152 can be movably connected to the second support groove 1144 of the back plate 114 of the base 11 and the second rolling groove 1235 of the connecting arm 123 of the first bracket 12. In one embodiment, the second support member 152 can be rolled between the back plate 114 of the base 11 and the connecting arm 123 of the first bracket 12. This helps to reduce the kinetic friction between the second support member 152 and the back plate 114, thereby helping to reduce the kinetic friction between the first bracket 12 and the base 11.

[0232] It is understandable that the cooperation relationship between the second support 152, the first bracket 12, and the base 11 can be set with reference to the cooperation relationship between the first support 151, the first bracket 12, and the base 11.

[0233] In some embodiments, the positioning ball 14, the first support member 151, and the second support member 152 are spaced apart. The lines connecting the positions of the positioning ball 14, the first support member 151, and the second support member 152 can form a triangle, thus making the support between the first bracket 12 and the base 11 more stable. In other embodiments, more support members can be provided between the first bracket 12 and the base 11.

[0234] In some embodiments, the line connecting the first support member 151 and the second support member 152 is a first connecting line, and the positioning ball 14, the first support member 151, and the second support member 152 are not collinear. Along the first direction, the projection of the positioning ball 14 onto the first connecting line is located between the first support member 151 and the second support member 152. It can be understood that with the first support member 151 and the second support member 152 positioned on both sides of the first shaft R1, the support of the first bracket 12 is more stable.

[0235] In some implementations, one of the first support member 151 and the second support member 152 may be selectively provided.

[0236] In some embodiments, the first magnetic member 155 may be disposed opposite to the metal insert 1142 in a direction parallel to the second direction. The first magnetic member 155 can interact with the metal insert 1142 to provide a magnetic attraction force parallel to the second direction, so that the first support 12 and the base 11 can be stably supported in the second direction. Exemplarily, the first magnetic member 155 may be a magnet or other magnetic component.

[0237] It is understood that the second magnetic attractor 156 in this embodiment can be made of magnetic material, and the second magnetic attractor 156 cooperates with the metal insert 1142 to provide magnetic attraction. In other embodiments, the second magnetic attractor 156 can also be made of magnetically conductive material (e.g., metal), and the anti-shake motor 1 can be further provided with a magnetic component, which cooperates with the second magnetic attractor 156 to provide magnetic attraction parallel to the second direction.

[0238] In some embodiments, the first coil 131 is disposed facing the first magnetic element 132 along a direction parallel to a third direction. The first coil 131 facing the first magnetic element 132 means that the winding plane of the first coil 131 faces the first magnetic element 132. When the first coil 131 is energized, the first magnetic element 132 can cooperate with the first coil 131, and the first arm 121 of the first support 12 receives a driving force parallel to the first direction, which drives the first support 12 to rotate around the first axis R1. The second coil 133 is disposed facing the second magnetic element 134 along a direction parallel to a third direction. The second coil 133 facing the second magnetic element 134 means that the winding plane of the second coil 133 faces the second magnetic element 134. When the second coil 133 is energized, the second magnetic element 134 can cooperate with the second coil 133, and the second arm 122 of the first support 12 receives a driving force parallel to the first direction, which drives the first support 12 to rotate around the first axis R1. When the first arm 121 and the second arm 122 of the first bracket 12 are simultaneously subjected to force, the resultant force on the two arms can be parallel to the first direction. The positioning ball 14 is limited by the groove surface in the positioning groove 110, restricting the translation of the first bracket 12 in the YZ plane. Under the limiting action of the positioning groove 110 on the positioning ball 14, the first bracket 12 can rotate around the first axis R1. For example, the forces on the first arm 121 and the second arm 122 can be in the same direction or in opposite directions. When the forces on the first arm 121 and the second arm 122 are in the same direction, they are not equal, resulting in an imbalance of forces on both sides of the first bracket 12, realizing rotation around the first axis R1; when the forces on the first arm 121 and the second arm 122 are in opposite directions, they can be equal or not equal, and the forces on the first arm 121 and the forces on the second arm 122 simultaneously provide the torque for the first bracket 12 to rotate around the first axis R1, resulting in higher driving efficiency.

[0239] It is understood that this embodiment illustrates that the first drive mechanism 13 and the third drive structure adopt a moving magnet drive method. In other embodiments, the first drive mechanism 13 and the third drive structure may also adopt a moving coil drive method.

[0240] In other embodiments, the first coil 131 is disposed facing the first magnetic element 132 in a direction parallel to the second direction. And / or, the second coil 133 is disposed facing the second magnetic element 134 in a direction parallel to the second direction.

[0241] In other embodiments, the positions of the first coil 131 and the first magnetic element 132 may be interchanged. And / or, the positions of the second coil 133 and the second magnetic element 134 may be interchanged.

[0242] For example, along a direction parallel to the second direction, the first sensor 135 can be disposed opposite to the first detection magnet 157. The first sensor 135 can be used to detect the magnetic field of the first detection magnet 157 to realize the displacement detection of the first bracket 12 relative to the base 11 in the YZ plane. It is understood that the figures illustrate that the first sensor 135 is fixed to the base 11 and the first detection magnet 157 is fixed to the first bracket 12. In other embodiments, the first sensor 135 may also be fixed to the first bracket 12 and the first detection magnet 157 may be fixed to the base 11.

[0243] In other embodiments, the first sensor 135 may be positioned opposite the first detection magnet 157 in a direction parallel to a third direction. The first sensor 135 may also detect the displacement of the first support 12 relative to the base 11 in the YZ plane.

[0244] Figure 23 is a structural schematic diagram of the second support 16 shown in Figure 8 in one embodiment. Figure 24 is a structural schematic diagram of the second support 16 shown in Figure 23 from another angle.

[0245] As shown in Figures 23 and 24, the second bracket 16 includes a first portion 161, a second portion 162, a support portion 163, a first connecting portion 164, and a second connecting portion 165. In Figure 23, the first portion 161 and the first connecting portion 164, the second portion 162, and the second connecting portion 165 are schematically distinguished by dashed lines. Exemplarily, the first portion 161 and the second portion 162 can be arranged opposite each other and spaced apart, and the support portion 163 can be fixedly connected between the first portion 161 and the second portion 162. The arrangement direction of the first portion 161 and the second portion 162 can be parallel to a third direction Y. The first connecting portion 164 can protrude from the surface of the first portion 161 facing away from the second portion 162. The second connecting portion 165 can protrude from the surface of the second portion 162 facing away from the first portion 161. The second connecting portion 165 and the first connecting portion 164 can be spaced apart.

[0246] It is understood that, for ease of describing the basic structure and shape of the second support 16, this embodiment describes the second support 16 in five parts. However, this does not affect the fact that the second support 16 can be a one-piece molded structure, that is, the first part 161, the second part 162, the support portion 163, the first connecting portion 164, and the third connecting portion can be integrally molded. In other embodiments, the second support 16 can also be formed by different independent structural components through an assembly process. For example, the first part 161 and the second part 162 of the second support 16 can be independent structural components and are fixedly connected to the support portion 163 by means of adhesive bonding, welding, etc.

[0247] For example, the first connecting portion 164 of the second bracket 16 may be provided with a first receiving groove 1641. The opening of the first receiving groove 1641 is located on the bottom surface 1642 of the first connecting portion 164.

[0248] For example, the second connecting portion 165 of the second bracket 16 may be provided with a second receiving groove 1651. The opening of the second receiving groove 1651 is located on the bottom surface 1652 of the second connecting portion 165.

[0249] Exemplarily, the first receiving groove 1641 and the second receiving groove 1651 may be arranged opposite each other in the third direction Y. In some embodiments, the arrangement direction of the first receiving groove 1641 and the second receiving groove 1651 may be parallel to or slightly angled to the third direction Y. Considering manufacturing and assembly errors, the arrangement direction of the first receiving groove 1641 and the second receiving groove 1651 may have an angle of less than or equal to 5° with the third direction Y.

[0250] For example, the support portion 163 may be provided with a first groove 1631. The opening of the first groove 1631 may be located on the bottom surface of the support portion 163.

[0251] In other embodiments, the second support 16 may not have the first portion 161 and the second portion 162.

[0252] Figure 25 is a schematic diagram of the assembly structure of the second support 16, the third magnetic component 172, and the second detection magnet 158 ​​shown in Figure 7 in one embodiment.

[0253] As shown in Figure 25, the third magnetic element 172 can be fixedly connected to the second bracket 16. In one embodiment, the third magnetic element 172 can be fixedly connected to the bearing portion 163 of the second bracket 16 and is located in the first groove 1631.

[0254] The third magnetic component 172 can be a magnet or other magnetic part. For example, the third magnetic component 172 can use a Heilbeck magnet scheme. That is, the third magnetic component 172 can be composed of three magnets, including a first magnet 1721, a second magnet 1722, and a third magnet 1723. The first magnet 1721, the second magnet 1722, and the third magnet 1723 of the third magnetic component 172 can be arranged along a second direction. The polarity directions of the first magnet 1721, the second magnet 1722, and the third magnet 1723 of the third magnetic component 172 are all different. For example, the polarity direction of the first magnet 1721 of the third magnetic component 172 is opposite to that of the third magnet 1723, and they intersect the second direction. Understandably, the polarity direction can be from the North Pole (N) towards the South Pole (S), or from the South Pole (S) towards the North Pole (N). The magnetic field strength of the Helbeck magnet scheme is stronger than that of the bimagnet scheme.

[0255] In other embodiments, the third magnetic element 172 may employ a dual magnet scheme, that is, the third magnetic element 172 may be composed of a first magnet 1721 and a second magnet 1722.

[0256] In one embodiment, the anti-shake motor 1 further includes a second detection magnet 158. The second detection magnet 158 ​​can be fixedly connected to the second bracket 16. Exemplarily, the second detection magnet 158 ​​can be fixedly connected to the support portion 163 of the second bracket 16 and located within the first groove 1631. The second detection magnet 158 ​​and the third magnetic element 172 can be arranged in a direction parallel to the second direction.

[0257] In one embodiment, the second detection magnet 158 ​​is disposed on the side of the second magnet 1722 of the third magnetic element 172 that is away from the first magnet 1721 of the third magnetic element 172, and the polarity direction of the second detection magnet 158 ​​is opposite to that of the second magnet 1722 of the third magnetic element 172. The second detection magnet 158 ​​can cooperate with the second magnet 1722 of the third magnetic element 172 to form a closed magnetic circuit and extend the magnetic field.

[0258] Figure 26 is a partial structural schematic diagram of the anti-shake motor 1 shown in Figure 7 in one embodiment. In Figure 26, the first part 161 and the first connecting part 164, the second part 162 and the second connecting part 165 are schematically distinguished by dashed lines.

[0259] As shown in Figure 26, the second bracket 16 is movably connected to the first bracket 12. The bearing portion 163 of the second bracket 16 can be located inside the first bracket 12. Exemplarily, along a third direction, the first portion 161 of the second bracket 16 can be disposed opposite to the first arm 121 of the first bracket 12, and the second portion 162 of the second bracket 16 can be disposed opposite to the second arm 122 of the first bracket 12. Along a first direction, the first connecting portion 164 of the second bracket 16 can be disposed opposite to the first arm 121 of the first bracket 12, and the second connecting portion 165 of the second bracket 16 can be disposed opposite to the second arm 122 of the first bracket 12.

[0260] Figure 27 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 26 at the GG line. Figure 28 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 26 at the HH line.

[0261] As shown in Figures 27 and 28, the second bracket 16 can be movably connected to the first bracket 12 via the first support member 153 and the second support member 154. Exemplarily, the first support member 153 can be rolled between the first connecting portion 164 of the second bracket 16 and the first bracket 12. The second support member 154 can be rolled between the second connecting portion 165 of the second bracket 16 and the first bracket 12. It is understood that, compared to a sliding connection between the first bracket 12 and the second bracket 16, the rolling connection of the first support member 153 and the second support member 154 between the first bracket 12 and the second bracket 16 helps to reduce the friction between the first bracket 12 and the second bracket 16.

[0262] In some embodiments, along the first direction, the first support member 153 can be connected between the first connecting portion 164 of the second bracket 16 and the first support arm 121 of the first bracket 12, and the second support member 154 can be connected between the second connecting portion 165 of the second bracket 16 and the second support arm 122 of the first bracket 12. Exemplarily, the first support member 153 can be fixedly connected within the first receiving groove 1641 of the first connecting portion 164 of the second bracket 16 and roll-connected to the first limiting groove 1212 of the first support arm 121 of the first bracket 12. The second support member 154 can be fixedly connected within the second receiving groove 1651 of the second connecting portion 165 of the second bracket 16 and roll-connected to the second limiting groove 1222 of the second support arm 122 of the first bracket 12. It is understood that the second bracket 16 is connected to the first bracket 12 on both sides of the bearing portion 163, which facilitates the smooth rotation of the second bracket 16.

[0263] In some embodiments, when the first support member 153 is rolled into the first limiting groove 1212, the first limiting groove 1212 includes three second limiting surfaces 1213 (see Figures 16 and 17), which form the three lateral faces of a triangular pyramid. At any given time, the first support member 153 and the three second limiting surfaces 1213 of the first limiting groove 1212 are in contact, and there are three contact points between the first support member 153 and the first limiting groove 1212. The lines connecting the three contact points form a triangle. The connection stability between the first support member 153 and the first limiting groove 1212 is relatively good. In other embodiments, the first limiting groove 1212 may also be a rectangular groove or other polygonal grooves.

[0264] In some embodiments, the second limiting groove 1222 includes two third limiting surfaces 1103. The two third limiting surfaces 1103 of the second limiting groove 1222 can be arranged along the second direction. In this way, the second support member 154 contacts the two third limiting surfaces 1103 in the second limiting groove 1222. The second support member 154 has two contact points in the second limiting groove 1222, and the two contact points are arranged along the second direction.

[0265] It is understandable that when the second bracket 16 and the first bracket 12 are movably connected, the second bracket 16 is limited relative to the first bracket 12 in the XY plane through the cooperation of the first limiting groove 1212 and the first support member 153. The second limiting groove 1222 and the second support member 154 cooperate to limit the relative movement of the second bracket 16 and the first bracket 12 in the X-axis direction.

[0266] In some embodiments, the anti-shake motor 1 further includes a second magnetic member 156. The second magnetic member 156 can be fixedly connected to the second bracket 16. In one embodiment, there can be two second magnetic members 156, one of which can be fixedly connected to the first connecting portion 164 of the second bracket 16, and the other of which can be fixedly connected to the second connecting portion 165 of the second bracket 16. The second magnetic member 156 fixedly connected to the first connecting portion 164 of the second bracket 16 can interact with the first magnetic member 132, and the second magnetic member 156 fixedly connected to the second connecting portion 165 of the second bracket 16 can interact with the second magnetic member 134 to provide a magnetic attraction force parallel to the first direction, for pressing the second bracket 16 onto the first bracket 12 to maintain a close fit between the second bracket 16 and the first bracket 12 during movement.

[0267] It is understood that the second magnetic attractor 156 in this embodiment uses a magnetically conductive material, and the second magnetic attractor 156 cooperates with the first magnetic component 132 and the second magnetic component 134 to provide magnetic attraction. In other embodiments, the second magnetic attractor 156 may also use a magnetic material, and the anti-shake motor 1 may be further provided with a magnetically conductive component, which cooperates with the second magnetic attractor 156 to provide magnetic attraction parallel to the first direction.

[0268] In other embodiments, the second support 16 and the first support 12 can be supported in a second direction. This application is not limiting.

[0269] Figure 29 is a partial structural schematic diagram of the anti-shake motor 1 shown in Figure 7 in one embodiment. Figure 30 is a partial cross-sectional schematic diagram of the anti-shake motor 1 shown in Figure 29 at line II in one embodiment.

[0270] As shown in Figures 29 and 30, along the first direction, the third magnetic element 172 on the second support 16 and the third coil 171 on the base 11 face each other. The third coil 171 and the third magnetic element 172 can cooperate with each other to provide a driving force to the second support 16 in the second direction, so as to drive the second support 16 to move relative to the first support 12. The first support 153 and the second support 154 are arranged opposite each other in a direction parallel to the second axis R2. Exemplarily, when the first support 153 and the second support 154 are ball bearings, the line connecting the center of the first support 153 and the center of the second support 154 is parallel to the second axis R2.

[0271] Understandably, the second support 16 and the first support 12 are connected by the cooperation of the first support member 153, the second support member 154, the first limiting groove 1212, and the second limiting groove 1222, which restricts the translation of the second support 16 in the XY plane. The second magnetic member 156 is used to press the second support 16 firmly onto the first support 12. When the second support 16 is subjected to a driving force along the second direction, it can rotate about the second axis R2 (parallel to the third direction).

[0272] In other embodiments, the third magnetic element 172 and the third coil 171 may also be arranged opposite each other along the second direction or the third direction.

[0273] In other embodiments, the positions of the third magnetic element 172 and the third coil 171 can be interchanged.

[0274] In some embodiments, the second sensor 173 is disposed on one side of the third coil 171. It is understood that, compared to a scheme where the second sensor 173 is disposed inside the third coil 171, in this embodiment, disposing the second sensor 173 outside the third coil 171 helps reduce the excitation interference of the third coil 171 on the second sensor 173 after it is energized, and helps improve the position detection accuracy of the second sensor 173, thereby improving control accuracy.

[0275] In some embodiments, among the multiple planes containing the first axis R1, the plane perpendicular to the second axis R2 is designated as the first plane S1. Figure 29 schematically illustrates the first plane S1, and Figure 30 is a cross-section of the structure shown in Figure 29 at the location of the first plane S1. The first plane S1 passes through the second sensor 173. It is understood that since the second support 16 is movably connected to the first support 12, and the first support 12 is movably connected to the base 11, when the second support 16 has a displacement relative to the first support 12, and the first support 12 also has a displacement relative to the base 11, if the second sensor 173 is located outside the first plane S1 and fixed to the base 11, the displacement detected by the second sensor 173 is affected by the movement of the first support 12. In this embodiment, the second sensor 173 passes through the first plane S1, which reduces the interference from the rotational displacement of the first support 12 around the second axis R2. The second sensor 173 can better detect the displacement of the second support 16 within the first plane S1, which is beneficial for improving the accuracy of the second sensor 173 in detecting the displacement of the second support 16.

[0276] In some embodiments, the second sensor 173 and the third coil 171 may be arranged opposite each other along a second direction. It is understood that, compared to the second sensor 173 and the third coil 171 being arranged opposite each other along a third direction, in this embodiment, the second sensor 173 and the third coil 171 may be spaced apart along the second direction. While the length of the anti-shake motor 1 in the third direction remains constant, in this embodiment, the third coil 171 may be longer in the third direction, with a longer portion used to cooperate with the third magnetic element 172 to drive the second support 16 to move.

[0277] For example, the distance L between the second sensor 173 and the third coil 171 can be greater than or equal to 0.01 mm and less than or equal to 10 mm. For instance, the distance L between the second sensor 173 and the third coil 171 can be 0.01 mm, 0.03 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. This distance, within a suitable range, helps reduce the excitation interference of the third coil 171 on the second sensor 173 after it is energized, and also avoids significantly increasing the size of the anti-shake motor 1.

[0278] In some embodiments, the second sensor 173 can be used to detect the magnetic field of the second detection magnet 158 ​​and / or the third magnetic element 172 to detect the displacement of the second bracket 16 in the XZ plane. Exemplarily, the second sensor 173 and the second detection magnet 158 ​​are arranged opposite each other along a first direction. The second sensor 173 simultaneously detects the magnetic fields of both the second detection magnet 158 ​​and the third magnetic element 172. The second detection magnet 158 ​​and the third magnetic element 172 can form a closed loop to extend the magnetic field, allowing the second sensor 173 to detect a larger magnetic field strength, which improves the detection accuracy of the second sensor 173 and thus enhances the control accuracy of the anti-shake motor 1.

[0279] In other embodiments, the anti-shake motor 1 may not have a second detection magnet 158, and the second sensor 173 may detect the magnetic field of the third magnetic element 172 to achieve position detection.

[0280] In other embodiments, the second sensor 173 may also be arranged at intervals with the third coil 171 along the first direction, or arranged in any direction within the XY plane.

[0281] In other embodiments, the second sensor 173 may also be disposed inside the third coil 171.

[0282] In other embodiments, when the third magnetic element 172 is fixed to the base 11, the second sensor 173 can be fixed to the second bracket 16.

[0283] Figure 31 is a structural schematic diagram of one embodiment of the housing 19 of the anti-shake motor 1 shown in Figure 8. Figure 32 is a partial cross-sectional schematic diagram of one embodiment of the anti-shake assembly 10 shown in Figure 3 at the JJ line.

[0284] As shown in Figures 31 and 32, the shape of the outer shell 19 can be adapted to the shape of the base 11. The outer shell 19 can be generally square-shaped.

[0285] For example, the housing 19 may include a top wall 191, a first side wall 192, a second side wall 193, a third side wall 194, and a fourth side wall 195. The first side wall 192, the second side wall 193, the third side wall 194, and the fourth side wall 195 may be located on the same side of the top wall 191 and fixedly connected to the top wall 191. In other embodiments, the housing 19 may also adopt other structures.

[0286] For example, the light inlet 101 can be located on the top wall 191. The light outlet 102 can be located on the fourth side wall 195. The light inlet 101 and the light outlet 102 can be interconnected. Light can propagate into the anti-shake motor 1 through the light inlet 101 along the first direction Z, and after being reflected by the first optical element 2, the light can propagate out of the anti-shake motor 1 along the second direction X.

[0287] For example, the outer casing 19 can be mounted on the base 11, and the first sidewall 192, the second sidewall 193, the third sidewall 194, and the fourth sidewall 195 of the outer casing 19 can be fixedly connected to the base 11. The third sidewall 194 of the outer casing 19 can be disposed opposite to the back plate 114 of the base 11.

[0288] For example, the housing 19 can be fixedly connected to the base 11 by means of adhesive, welding or other methods. The housing 19 can be assembled and fitted with the base 11 to jointly encapsulate and protect the internal structure of the anti-shake motor 1.

[0289] The second embodiment, which shares the same technical content as the first embodiment, will not be repeated here: Figure 33 is a partial structural schematic diagram of the anti-shake motor 1 shown in Figure 3 in another embodiment. Figure 34 is a partial cross-sectional schematic diagram of the anti-shake motor 1 shown in Figure 7 at line KK in another embodiment.

[0290] As shown in Figures 33 and 34, the first detection magnet may not be provided in this embodiment. The third coil 171 includes two sub-coils 1711, which are arranged at intervals along a third direction. Along this third direction, the second sensor 173 is disposed between the two sub-coils 1711. This third direction is perpendicular to both the first and second directions. It is understood that in this embodiment, along the first direction, the second sensor 173 can be disposed opposite to the third magnetic element 172. The second sensor 173 detects the magnetic field of the third magnetic element 172 to detect the displacement of the second support 16. Compared to the previous embodiment where the second sensor 173 and the third coil 171 are arranged along the second direction, in this embodiment, the second sensor 173 and the third coil 171 are arranged along the third direction, thus not increasing the size of the anti-shake motor 1 in the second direction. Those skilled in the art can selectively configure the arrangement of the third coil 171 and the second sensor 173.

[0291] The third embodiment, which shares the same technical content as the previous embodiment, will not be repeated here: The previous embodiment illustrated that the first bracket 12 and the second bracket 16 are movably connected on both sides of the support portion 163. In this embodiment, along the second direction, the first bracket 12 and the second bracket 16 are connected on the back side 1633 of the support portion 163. The following will describe in detail, with reference to the accompanying drawings, an embodiment in which the first bracket 12 and the second bracket 16 are connected on the back side 1633 of the support portion 163.

[0292] Figure 35 is a structural schematic diagram of the anti-shake motor 1 of the anti-shake assembly shown in Figure 4 in another embodiment. Figure 36 is an exploded structural schematic diagram of the anti-shake motor 1 shown in Figure 35 in some embodiments.

[0293] As shown in Figures 35 and 36, the anti-shake motor 1 may include a base 11, a first bracket 12, a first drive mechanism 13, a positioning ball 14, a first support member 151, a second support member 152, a second bracket 16, a second drive mechanism 17, a circuit board assembly 18, a first support member 153, a second support member 154, a first magnetic suction member 155, and a housing 19. The arrangement of the base 11, the first drive mechanism 13, the positioning ball 14, the first support member 151, the second support member 152, the second drive mechanism 17, the circuit board assembly 18, and the housing 19 can refer to the arrangement in the embodiments described above, and will not be repeated below.

[0294] Figure 37 is a structural schematic diagram of one embodiment of the first support 12 shown in Figure 36. Figure 38 is a structural schematic diagram of the first support 12 shown in Figure 37 from another angle.

[0295] As shown in Figures 37 and 38, the first bracket 12 includes a first arm 121, a second arm 122, a connecting arm 123, and a protrusion 124. The protrusion 124 can be fixedly connected to the first surface 1231 of the connecting arm 123, along with the first arm 121 and the second arm 122. Exemplarily, the first arm 121, the second arm 122, the connecting arm 123, and the protrusion 124 can be integrally formed structural components.

[0296] Exemplarily, the protrusion 124 of the first bracket 12 may be provided with a first limiting groove 1212 and a second limiting groove 1222. The opening of the first limiting groove 1212 and the opening of the second limiting groove 1222 may be located on the surface of the protrusion 124 away from the connecting arm 123. It is understood that the first limiting groove 1212 originally provided on the first support arm 121 and the second limiting groove 1222 on the second support arm 122 are provided on the protrusion 124 of the first bracket 12 in this embodiment. The first limiting groove 1212 and the second limiting groove 1222 may be used to accommodate the first support member 153 and the second support member 154, and to limit the positioning of the first support member 153 and the second support member 154, respectively.

[0297] For example, the second limiting groove 1222 includes two third limiting surfaces 1103. The two third limiting surfaces 1103 of the second limiting groove 1222 can be arranged along the first direction. In this way, the second support member 154 contacts the two third limiting surfaces 1103 in the second limiting groove 1222. The second support member 154 has two contact points in the second limiting groove 1222, and the two contact points are arranged along the first direction.

[0298] In other embodiments, the first bracket 12 may not have the protrusion 124, and the first limiting groove 1212 and the second limiting groove 1222 may be located on the connecting arm 123. The opening of the first limiting groove 1212 and the opening of the second limiting groove 1222 may be located on the first surface 1231 of the connecting arm 123.

[0299] In some embodiments, the first bracket 12 may be provided with a clearance hole 125, which can pass through the connecting arm 123. The clearance hole 125 can be connected to the first surface 1231 and the second surface 1232 of the connecting arm 123. The clearance hole 125 is used to avoid the second bracket 16.

[0300] Figure 39 is a structural schematic diagram of one embodiment of the second support 16 shown in Figure 36.

[0301] As shown in Figure 39, the second bracket 16 may be provided with a first receiving groove 1641 and a second receiving groove 1651. The openings of the first receiving groove 1641 and the second receiving groove 1651 may be located on the back side 1633 of the bearing portion 163 of the second bracket 16. The first receiving groove 1641 and the second receiving groove 1651 may be used to accommodate the first support member 153 and the second support member 154, respectively.

[0302] For example, the support portion 163 of the second bracket 16 may be provided with a relief groove 1632. The opening of the relief groove 1632 may be located on the back side 1633 of the support portion 163 of the second bracket 16. The relief groove 1632 may be used to accommodate the protrusion 124 of the first bracket 12. The openings of the first receiving groove 1641 and the second receiving groove 1651 may be located at the bottom of the relief groove 1632.

[0303] For example, the support portion 163 of the second bracket 16 may be provided with a third mounting groove 1236. The opening of the third mounting groove 1236 may be located on the back side 1633 of the support portion 163 of the second bracket 16. The third mounting groove 1236 may be used to accommodate the first magnetic member 155. It is understood that the first magnetic member 155 originally provided on the first bracket 12 may be provided on the second bracket 16 in this embodiment.

[0304] Figure 40 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 35 at line LL. Figure 41 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 35 at line MM.

[0305] As shown in Figures 40 and 41, when the first bracket 12 and the second bracket 16 are assembled, the back surface 1633 of the bearing portion 163 of the second bracket 16 faces the connecting arm 123 of the first bracket 12. The first bracket 12 and the second bracket 16 can be movably connected in a second direction. Exemplarily, along the second direction, the first support member 153 is rolled between the first bracket 12 and the bearing portion 163, and the second support member 154 is rolled between the first bracket 12 and the bearing portion 163. The first support member 153 and the second support member 154 are spaced apart and arranged opposite each other in a direction parallel to the second axis R2. It is understood that the first bracket 12 movably connects the bearing portion 163 of the second bracket 16 in the second direction. In the third direction, the structural length of both sides of the bearing portion 163 of the second bracket 16 is not limited, and the size of the second bracket 16 in the third direction can be set to be smaller. The bearing portion 163 of the second bracket 16 can be provided with a first connecting portion 164 and a second connecting portion 165, or it can be omitted. In this embodiment, the connection scheme of the first bracket 12 and the second bracket 16 is beneficial to reducing the length of the second bracket 16 in the third direction.

[0306] In some embodiments, the first support member 153 is located within the first receiving groove 1641 and the first limiting groove 1212. The second support member 154 is located within the second receiving groove 1651 and the second limiting groove 1222. Along the second direction, the first support member 153 and the second support member 154 are rolledly connected between the bearing portion 163 of the first bracket 12 and the second bracket 16.

[0307] It is understandable that during manufacturing, the first limiting groove 1212 and the second limiting groove 1222 need to meet dimensional requirements in the third direction. The first limiting groove 1212 and the second limiting groove 1222 must be within a certain length range to effectively limit the first support member 153 and the second support member 154. Compared to the scheme in the previous embodiment where the first bracket 12 and the second bracket 16 are connected on both sides of the bearing portion 163 of the second bracket 16, in this embodiment, the first bracket 12 is movably connected to the bearing portion 163 of the second bracket 16 in the second direction. The bearing portion 163 of the second bracket 16 has a larger dimension in the third direction, which can meet the dimensional requirements of the first limiting groove 1212 and the second limiting groove 1222.

[0308] In some embodiments, the first bracket 12 and the second support member 154 can be rolledly connected to the first bracket 12 within the clearance groove 1632 of the second bracket 16. Exemplarily, the protrusion 124 of the first bracket 12 can extend into the clearance groove 1632 of the second bracket 16. Along the second direction, the first support member 153 and the second support member 154 are rolledly connected between the protrusion 124 of the first bracket 12 and the bearing portion 163 of the second bracket 16. It is understood that, compared to the scheme where the connecting arm 123 of the first bracket 12 is directly connected to the second bracket 16, in this embodiment, by providing the protrusion 124 of the first bracket 12 and the clearance groove 1632 of the second bracket 16, the connection position of the first bracket 12 and the second bracket 16 can be closer to the center of gravity of the second bracket 16, which is beneficial to the stability of the movement of the second bracket 16.

[0309] In some embodiments, the first magnetic member 155 can be fixedly connected to the second bracket 16. Along the second direction, the connecting arm 123 of the first bracket 12 can be located between the bearing portion 163 of the second bracket 16 and the base 11. Exemplarily, the first magnetic member 155 can be fixedly connected to the bearing portion 163 of the second bracket 16 and located within the third mounting groove 1236. Along a direction parallel to the second direction, the first magnetic member 155 can be disposed opposite to the metal insert 1142. The first magnetic member 155 can interact with the metal insert 1142 to provide a magnetic attraction force parallel to the second direction, allowing the second bracket 16 and the base 11 to clamp the first bracket 12, so that the second bracket 16, the first bracket 12, and the base 11 can be stably supported in the second direction.

[0310] For example, the second bracket 16 may be partially located within the clearance hole 125 of the first bracket 12, and the first magnetic member 155 may act through the clearance hole 125 of the first bracket 12 and the metal insert 1142. It is understood that by providing the clearance hole 125, the first bracket 12 allows the first magnetic member on the second bracket 16 to be closer to the metal insert 1142 of the base 11, resulting in a greater interaction force between the two.

[0311] The fourth embodiment, which shares the same technical content as the third embodiment, will not be repeated here: In the previous embodiment, a portion of the first driving mechanism 13 is disposed on the base 11 and a portion on the first bracket 12, directly driving the first bracket 12 to move relative to the base 11. In this embodiment, the first driving mechanism 13 may be partially disposed on the base 11 and partially disposed on the second bracket 16, with the first driving structure driving the second bracket 16 to move relative to the base 11. The first bracket 12 and the second bracket 16 are connected by a limiting structure, allowing the second bracket 16 to drive the first bracket 12 to move relative to the base 11. It is understood that this application is not limited to the first driving mechanism 13 directly driving the first bracket 12; the anti-shake motor 1 may also indirectly drive the first bracket 12 to rotate around the first axis R1 via the second bracket 16.

[0312] The following description, in conjunction with the accompanying drawings, introduces several embodiments in which the first drive mechanism 13 drives the second bracket 16 to rotate the first bracket 12 relative to the base 11 around the first axis R1. Figure 42 is a structural schematic diagram of the anti-shake motor 1 of the anti-shake assembly shown in Figure 4 in another embodiment. Figure 43 is an exploded structural schematic diagram of the anti-shake motor 1 shown in Figure 42 in some embodiments.

[0313] As shown in Figures 42 and 43, the anti-shake motor 1 may include a base 11, a first bracket 12, a first drive mechanism 13, a positioning ball 14, a first support member 151, a second support member 152, a second bracket 16, a second drive mechanism 17, a circuit board assembly 18, a first support member 153, a second support member 154, a first magnetic suction member 155, and a housing 19. The arrangement of the base 11, positioning ball 14, first support member 151, second support member 152, second drive mechanism 17, circuit board assembly 18, first support member 153, second support member 154, first magnetic suction member 155, and housing 19 can refer to the arrangement in the embodiments described above, and will not be repeated below.

[0314] Figure 44 is a structural schematic diagram of one embodiment of the second support 16 shown in Figure 43. Figure 45 is a structural schematic diagram of the second support 16 shown in Figure 44 from another angle.

[0315] As shown in Figures 44 and 45, the second support 16 may include a support portion 163, a first connecting portion 164, and a second connecting portion 165. The first connecting portion 164 may have a second groove 1211. The opening of the second groove 1211 may be located on the surface of the first connecting portion away from the support portion 163. The second connecting portion 165 may have a third groove 1221. The opening of the third groove 1221 may be located on the surface of the first connecting portion away from the second connecting portion 165. The second groove 1211 and the third groove 1221 may be used to accommodate a portion of the first drive mechanism 13.

[0316] Figure 46 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 42 at line NN. Figure 47 is a partial cross-sectional view of one embodiment of the anti-shake motor 1 shown in Figure 42 at line OO.

[0317] As shown in Figures 46 and 47, the first magnetic element 132 of the first driving mechanism 13 can be fixedly connected to the second groove 1211 of the first connecting portion 164 of the second bracket 16. The second magnetic element 134 of the first driving mechanism 13 can be fixedly connected to the third groove 1221 of the second connecting portion 165 of the second bracket 16. It is understood that in this embodiment, the first bracket 12 may not have a first arm and a second arm. The first magnetic element 132 and the second magnetic element 134 of the first driving mechanism 13 are embedded in the second bracket 16. The first driving mechanism 13 can be used to drive the second bracket 16 to move relative to the base 11.

[0318] In other embodiments, the positions of the first coil 131 and the first magnetic element 132 can be interchanged. The positions of the second coil 133 and the second magnetic element 134 can also be interchanged.

[0319] In some embodiments, the second bracket 16 drives the first bracket 12 to move relative to the base 11 through the cooperation of the first limiting groove 1212, the second limiting groove 1222, the first support member 153, and the second support member 154. The first bracket 12 can rotate relative to the base about the first axis R1 through the cooperation of the positioning ball 14 and the positioning groove 110 of the base 11.

[0320] For example, the second limiting groove 1222 includes two third limiting surfaces 1103. The two third limiting surfaces 1103 of the second limiting groove 1222 can be arranged along a first direction. In this way, the second support member 154 contacts the two third limiting surfaces 1103 in the second limiting groove 1222. The second support member 154 has two contact points in the second limiting groove 1222, and the two contact points are arranged along the first direction. It can be understood that by setting the arrangement direction of the two third limiting surfaces 1103 of the second limiting groove 1222, when the second bracket 16 is driven by the first driving mechanism 13, the first support member 153 is fixedly connected to the second bracket 16 and abuts against the third limiting surfaces 1103, applying a driving force in the first direction to the first bracket 12.

[0321] For example, when the second bracket 16 is driven by the first driving mechanism 13, the first support member 153 can be fixedly connected to the second bracket 16 and abut against the first limiting groove 1212 to apply a driving force in the first direction to the first bracket 12.

[0322] It is understood that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0323] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0324] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
