Description

Technical Field

[0001] This application relates to the field of shooting equipment technology, and in particular to a base, motor, camera module and electronic device. Background Technology

[0002] 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.

[0003] Traditional telephoto modules with prism-based image stabilization typically include a separate prism OIS motor and a separate focusing motor, which are connected and fixed together with adhesive. This module connection scheme involves a large number of motors and module components, and the assembly process is complex, resulting in high component and manufacturing costs. Utility Model Content

[0004] This application provides a base, a motor, a camera module, and an electronic device.

[0005] In a first aspect, embodiments of this application provide a base. The base has a light inlet and a light outlet. Light propagates into the base through the light inlet along a first direction and exits the base through the light outlet along a second direction, the first direction being different from the second direction. The base includes a first support portion and a second support portion, which are arranged in the second direction and are integrally formed structural components. The first support portion is used to mount a first image stabilization bracket, which is rotatable relative to the first support portion around a first axis, the first axis being parallel to the second direction. The second support portion is used to mount a focusing bracket. The first support portion is provided with a positioning groove, which includes three limiting surfaces. The three limiting surfaces form the three sides of a triangular pyramid, and the first axis passes through the center of the space enclosed by the three limiting surfaces.

[0006] Understandably, the base can simultaneously support both the first image stabilization bracket and the focusing bracket. The first and second support parts are integrally molded structural components, eliminating the need for additional connections (such as adhesive bonding) between them, thus reducing the reliability risks of traditional adhesive bonding methods, such as delamination and cracking. Compared to traditional solutions where the focusing bracket and image stabilization bracket are driven by two separate motors, resulting in numerous component modules and complex assembly processes within the camera module, leading to increased component and manufacturing costs, the base of this application addresses the reliability risks of delamination and cracking when the focusing and image stabilization motors are connected by adhesive. When applied to the motors, the focusing bracket and image stabilization bracket are mounted on the same base, sharing the same base, which reduces the number of motor components, assembly processes, and complexity, thereby lowering motor costs.

[0007] 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.

[0008] In one possible implementation, the base includes a base plate, a back plate, and a first fixing post. The back plate and the first fixing post are fixedly connected to the same side of the base plate and are spaced apart in a second direction. The base plate includes a first plate portion and a second plate portion arranged along the second direction. The back plate is fixedly connected to the first plate portion. The first plate portion and the back plate form a first load-bearing part. The first fixing post is fixedly connected to the second plate portion. The first fixing post and the second plate portion form a second load-bearing part. The back plate, the first fixing post, and the base plate enclose a first mounting space. A positioning groove is located on the back plate, and the opening of the positioning groove faces the first mounting space. The first mounting space is used to accommodate a first anti-shake bracket.

[0009] Understandably, when the base is used for the motor, to support the focusing bracket and the first image stabilization bracket, the focusing bracket and the first image stabilization bracket are installed on different parts of the base plate, and the first fixing post can be used to separate the two and reduce the risk of interference.

[0010] In one possible implementation, the base further includes a second, third, and fourth fixing post. The second, third, and fourth fixing posts are connected to the same side of the second plate as the first fixing post. Along a second direction, the first and second fixing posts are positioned opposite each other and spaced apart, with the second fixing post located on the side of the first fixing post away from the back plate. Along a third direction, the first and fourth fixing posts are positioned opposite each other and spaced apart, and along the second direction, the third and fourth fixing posts are positioned opposite each other and spaced apart, with the third fixing post located on the side of the fourth fixing post away from the back plate. The second, third, and fourth fixing posts constitute a second load-bearing portion.

[0011] Understandably, the second plate, first fixed post, second fixed post, third fixed post, and fourth fixed post can enclose a second mounting space, which can be used to accommodate structural components such as the focusing bracket. When the base is used to support the focusing bracket, the first fixed post, second fixed post, third fixed post, and fourth fixed post can be used to limit the movement of the focusing bracket, preventing it from exceeding its travel range during movement and interfering with the first image stabilization bracket.

[0012] Secondly, embodiments of this application provide a motor. The motor includes a first image stabilization bracket, a focusing bracket, and a base as described in any one of claims 1 to 1. The first image stabilization bracket is movably connected to a first support portion, and the focusing bracket is movably connected to a second support portion. The focusing bracket is capable of moving relative to the second support portion along a second direction. The image stabilization motor also includes positioning balls, which are movably connected between the base and the first image stabilization bracket. The positioning balls and positioning grooves are arranged along the second direction, and the positioning balls are movably connected within the positioning grooves and simultaneously contact three limiting surfaces.

[0013] It is understood that the motor in this application can be used to drive the optical path folding element for image stabilization, and also to drive the focusing lens group for focusing. By integrating the focusing and image stabilization functions into one motor, only one motor is needed to complete the focusing and image stabilization functions when the motor is used in the camera module. This helps to reduce the number of components, assembly steps, and complexity of the camera module, thereby reducing the cost of the camera module.

[0014] This application achieves positioning of the first axis through the cooperation of positioning balls and positioning grooves, allowing the first image stabilization 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 methods, this point-to-surface contact positioning method is less affected by the installation and manufacturing precision of 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 image stabilization bracket and the base. This reduces the likelihood of jamming when the first image stabilization bracket moves relative to the base, and improves motor control precision. When the motor is used in a camera module, the imaging quality of the camera module is better. In addition, when the positioning balls are movably connected within the positioning grooves, there are always three contact points at any given time, providing excellent limiting and support for the positioning balls.

[0015] In one possible implementation, the motor further includes a first gasket, which is fixedly connected to the base, and the first anti-shake bracket and the first gasket are arranged opposite to each other along the second direction.

[0016] Understandably, during motor assembly, the first anti-shake bracket is installed first, followed by the first shim. On one hand, with the shim not installed, there is more space for installing the first anti-shake bracket, making its installation easier and reducing the likelihood of collisions with surrounding components. On the other hand, installing the first shim onto the base after the first anti-shake bracket is installed reduces the gap between the bracket and the base, improving motor reliability. For example, when the motor is impacted or dropped, the first anti-shake bracket will move less, its offset will be smaller, or the impact between it and surrounding components will be less.

[0017] In one possible implementation, the first gasket is flexible.

[0018] Understandably, flexible pads help reduce motor noise. For example, when the motor is impacted or dropped, the anti-shake bracket collides with the pad first, resulting in less noise during the collision.

[0019] In one possible implementation, the positioning ball is movably connected to the first anti-shake bracket. Alternatively, the positioning ball is fixedly connected to the first anti-shake bracket.

[0020] Understandably, the positioning ball bearing is fixedly connected to the first anti-shake bracket. This provides better connection strength between the positioning ball bearing and the first anti-shake bracket, making it less prone to movement of the positioning ball bearing relative to the first anti-shake bracket. When the motor detects the position of the first anti-shake bracket relative to the base, the interference from the positioning ball bearing is minimal, resulting in better motor control precision.

[0021] The positioning ball bearing can also be movably connected to the first image stabilization bracket. This reduces the risk of the positioning ball bearing getting stuck.

[0022] In one possible implementation, the motor further includes a second anti-shake bracket, which is movably connected to the first anti-shake bracket. The second anti-shake bracket is capable of rotating relative to the first anti-shake bracket about a second axis, which is perpendicular to both the first and second directions.

[0023] It is understandable that when the motor is used to drive the optical path folding element for image stabilization, the second image stabilization bracket can be used to support the optical path folding element, which can rotate around the first axis and the second axis, thus achieving high image stabilization accuracy.

[0024] In one possible implementation, the motor further includes a first support member and a second support member, which are rotatably connected between a first stabilizing bracket and a second stabilizing bracket along a first direction or a second direction. The first support member and the second support member are spaced apart and arranged opposite to each other along a second axis. The motor also includes a magnetic magnet and a magnetic plate, one of which is fixed to the first stabilizing bracket and the other is fixed to the second stabilizing bracket. The magnetic magnet and the magnetic plate are arranged opposite to each other along the second direction. The center of the magnetic magnet and the second axis are both located in a first plane, and the first axis is parallel to the first plane.

[0025] It is understood that the first and second support members are spaced apart and arranged opposite each other along the second axis. The magnetic attraction between the magnetic magnet and the magnetic plate can, in the second direction, ensure stable support for the first and second image stabilization brackets. The center of the magnetic magnet is coplanar with the second axis, and the first axis is parallel to the first plane. The magnetic attraction of the magnetic magnet can pass through the second axis, which helps to reduce the interference torque that hinders the rotation of the second image stabilization bracket around the second axis.

[0026] In one possible implementation, the center of the magnetic chuck is located within the first plane.

[0027] Understandably, the center of the magnetic stabilizing plate can also be coplanar with the second axis, which can further reduce the interference torque that prevents the second image stabilizing bracket from rotating around the second axis.

[0028] In one possible implementation, the magnetic magnet is a single-sided bipolar magnet.

[0029] It is understood that a single-sided bipolar magnet refers to a magnet that simultaneously possesses both north and south poles on one side. Compared to a single-sided unipolar magnet, the magnetic attractor in this embodiment is a single-sided bipolar magnet, which helps to concentrate the magnetic field near the magnetic attractor and reduce electromagnetic interference between the magnetic attractor and other nearby devices. Furthermore, compared to assembling two magnets, the single-sided bipolar configuration of a single magnet can reduce assembly process costs.

[0030] In one possible implementation, the magnetic magnet is fixed to the second anti-shake bracket, and the surface of the magnetic magnet facing the magnetic plate is the first surface, which has two polarities.

[0031] Understandably, the first surface has two polarities, meaning it simultaneously possesses both north and south magnetic poles. This results in a stronger magnetic attraction between the magnet and the magnetic plate, leading to better stability between the second and first image stabilization brackets.

[0032] In one possible implementation, the surface of the magnetic magnet facing the magnetic sheet is a first surface, which is an arc surface that bulges in the direction of the magnetic sheet.

[0033] It is understandable that when the first surface is curved compared to a flat surface, the minimum distance between the magnetic magnet and the magnetic plate changes less in the second direction during the rotation of the second stabilization bracket, and the magnetic attraction force between the magnetic magnet and the magnetic plate changes less, which is beneficial to the stability between the second stabilization bracket and the first stabilization bracket.

[0034] In one possible implementation, the first surface is a sphere, the center of the sphere on the first surface is located on the second axis, and the projection of the center of the sphere on the first surface coincides with the first axis along the first direction.

[0035] It is understandable that during the rotation of the second image stabilization bracket around the second axis, the minimum distance between the magnetic magnet and the magnetic plate in the second direction remains unchanged, and the magnitude of the magnetic attraction between the magnetic magnet and the magnetic plate remains unchanged, which is beneficial to the stability between the second image stabilization bracket and the first image stabilization bracket.

[0036] In one possible implementation, the first image stabilization bracket includes a first arm, a second arm, and a connecting arm. Along a third direction, the connecting arm connects between the first and second arms. A positioning ball is movably connected between the connecting arm and a base. This third direction is perpendicular to both the first and second directions. Along either the first or second direction, a first support member is rotatably connected between the first arm and the second image stabilization bracket, and a second support member is rotatably connected between the second arm and the second image stabilization bracket. Alternatively, along the second direction, the first support member and the second support member are rotatably connected between the connecting arm and the second image stabilization bracket.

[0037] In one possible implementation, the motor further includes a stabilization drive mechanism for driving the first stabilization bracket to rotate relative to the first load-bearing part about a first axis.

[0038] It is understandable that the anti-shake drive mechanism can use coil magnet drive, piezoelectric ceramic drive, or shape memory alloy drive.

[0039] In one possible implementation, the image stabilization drive mechanism includes a first coil and a first magnetic element, one of which is fixed to a base and the other to a first support arm. The first coil faces the first magnetic element, and the first coil and the first magnetic element are used to drive the first image stabilization bracket to rotate relative to the first support portion about a first axis. And / or, the image stabilization drive mechanism further includes a second coil and a second magnetic element, one of which is fixed to a base and the other to a second support arm. The second coil faces the second magnetic element, and the second coil and the second magnetic element are used to drive the first image stabilization bracket to rotate relative to the first support portion about a first axis.

[0040] Understandably, when the first coil is energized, the first magnetic component can cooperate with the first coil, and the first arm of the first image stabilization bracket receives a driving force parallel to the first direction, which drives the first image stabilization bracket to rotate relative to the first support portion around the first axis. And / or, when the second coil is energized, the second magnetic component can cooperate with the second coil, and the second arm of the first image stabilization bracket receives a driving force parallel to the first direction, which drives the first image stabilization bracket to rotate relative to the first support portion around the first axis. When the first and second arms of the first image stabilization bracket are simultaneously subjected to force, the resultant force on the two arms can be parallel to the first direction. The positioning ball is limited by the groove surface in the positioning groove, restricting the translation of the first image stabilization bracket in the YZ plane. Under the limiting effect of the positioning groove on the positioning ball, the first image stabilization bracket can rotate around the first axis.

[0041] The forces acting on the first and second arms can be in the same direction or opposite directions. When the forces on the first and second arms are in the same direction, they are not equal, resulting in an imbalance of forces on both sides of the first image stabilization bracket, enabling rotation around the first axis. When the forces on the first and second arms are in opposite directions, they can be equal or unequal. The forces on the first and second arms simultaneously provide the first image stabilization bracket with the torque required to rotate around the first axis, resulting in higher drive efficiency.

[0042] In one possible implementation, the image stabilization drive 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 second image stabilization bracket. The first coil faces the first magnetic element. The first coil and the first magnetic element are used to drive the second image stabilization bracket to move relative to the first support portion. The second image stabilization bracket drives the first image stabilization bracket to rotate relative to the first support portion around a first axis.

[0043] It is understood that the image stabilization drive structure can drive the second image stabilization bracket to rotate, thereby causing the first image stabilization bracket to rotate relative to the first support portion around the first axis. The image stabilization drive structure can be configured in various ways, and is not limited to those shown in this application.

[0044] In one possible implementation, the image stabilization drive mechanism further 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 image stabilization bracket. Along the first or second direction, the third coil faces the third magnetic element, and the third coil and the third magnetic element are used to drive the second image stabilization bracket to rotate relative to the first support portion about the second axis.

[0045] Understandably, the third coil and the third magnetic component can cooperate to provide a driving force to the second image stabilization bracket in the second direction, thereby driving the second image stabilization bracket to rotate relative to the first image stabilization bracket around the second axis. The image stabilization drive mechanism uses a moving magnet drive method, with the coil fixed on the base, which helps reduce the difficulty of supplying power to the coil.

[0046] In one possible implementation, the motor further includes a stop member, which is fixedly connected to the base. Along the second direction, the stop member is located on the side of the first anti-shake bracket away from the positioning ball, and the stop member and the first anti-shake bracket are spaced apart.

[0047] Understandably, by setting up a stop, the movement space of the first anti-shake bracket in the second direction can be controlled, preventing excessive displacement of the first anti-shake bracket in the second direction, which could cause the positioning ball to fall off and prevent the movement of the first anti-shake bracket from jamming. The stop is set at intervals with the first and second anti-shake brackets to prevent the stop from interfering with the rotation of the first and second anti-shake brackets.

[0048] In one possible implementation, the distance between the stop and the first stabilizing bracket along the second direction is in the range of 0.005 mm to 0.5 mm.

[0049] It is understandable that the distance between the stop and the first anti-shake bracket is within a suitable range along the second direction. On the one hand, this can prevent the first anti-shake bracket from displacing too much in the second direction, which would cause the positioning ball to fall off. On the other hand, it can effectively prevent the stop from interfering with the rotation of the first anti-shake bracket.

[0050] In one possible implementation, along the second direction, the gap D1 between the first anti-shake 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).

[0051] Understandably, while ensuring the reliability and stability of the positioning balls within the positioning groove, the base and the first anti-shake bracket should have as little movement interference as possible.

[0052] 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.

[0053] Understandably, the contact depth between the positioning ball and the positioning groove can be within a suitable range to ensure that the positioning ball can remain stably within the positioning groove during movement and is not easily dislodged during the process of contact.

[0054] In one possible implementation, the first image stabilization bracket includes a first arm, a second arm, and a connecting arm. Along a third direction, the connecting arm connects between the first and second arms. Positioning ball bearings are movably connected between the connecting arm and a base. The third direction is perpendicular to both the first and second directions. The motor also includes a second washer, which is fixedly connected to the base. Along the second direction, the first washer is located between the first arm and the base, and the second washer is located between the second arm and the base.

[0055] It is understood that the first and second shims are respectively positioned opposite to the two sides of the first image stabilization bracket, reducing the gap between the first image stabilization bracket and the base from multiple locations, thereby further improving the reliability of the motor. The number of shims can be set according to requirements, and is not limited to the two examples in this application. Furthermore, the position of the shims can also be adaptively adjusted according to actual conditions, and can be used to reduce the gap at any position around the first image stabilization bracket.

[0056] In one possible implementation, the motor further includes a focusing drive mechanism for driving the focusing bracket to move relative to the second support portion in a second direction.

[0057] It is understandable that the focusing drive mechanism can be driven by coil magnets, piezoelectric ceramics, or shape memory alloys.

[0058] Thirdly, embodiments of this application provide a camera module. The camera module includes an optical path folding element, a focusing lens group, and a motor. The optical path folding element is mounted on a first image stabilization bracket of the motor, and the focusing lens group is mounted on a focusing bracket of the motor. Light propagates into the motor through a light inlet in a first direction, is reflected by the optical path folding element, passes through the focusing lens group, and then propagates out of the motor through a light outlet in a second direction after exiting the focusing lens group.

[0059] Understandably, compared to traditional technical solutions, where the focusing bracket and image stabilization bracket of the camera module are driven by two separate motors, the numerous component modules of these two motors and the complex assembly process within the camera module increase the component and manufacturing costs. Furthermore, when the focusing motor and image stabilization motor are connected by adhesive, there are reliability risks such as delamination and cracking. The motor in this application can be used to drive the optical path folding element for image stabilization and also to drive the focusing lens group for focusing. Integrating the focusing and image stabilization functions into a single motor reduces the number of components, assembly processes, and complexity of the motor / camera module, thereby lowering the cost of the motor / camera module. Simultaneously, the integrated focusing and image stabilization motor, by sharing a single molded structural component (the first and second support parts of the base are single molded components), reduces the reliability risks of delamination and cracking associated with traditional adhesive connections.

[0060] In one possible implementation, the camera module also includes a housing, which is fixedly connected to the base. The housing and the base enclose a receiving space, in which the optical path folding element and the focusing lens group are located.

[0061] Understandably, the housing can be fixedly connected to the motor base and can be used to protect the motor, optical path folding components, focusing lens group, etc.

[0062] In one possible implementation, the housing includes a top wall and a side wall. The side wall is connected to the periphery of the top wall and fixedly connected to the base. The top wall has a first through hole, and the side wall has a second through hole. The first through hole is connected to the light inlet hole of the base, and the second through hole is connected to the light outlet hole of the base. Light propagates into the motor by passing through the first through hole and the light inlet hole in sequence along a first direction. After the light exits the focusing lens group, it propagates out of the motor by passing through the light outlet hole and the second through hole in sequence along a second direction.

[0063] Understandably, the housing can be assembled and fitted with the base to jointly encapsulate and protect the internal structure of the motor. The housing is installed after the optical path folding components, focusing lens group, and motor are assembled. Connecting the housing and base during the camera module assembly process avoids the housing interfering with the installation of the focusing lens group. A first and second through-hole are provided on the housing to allow light to pass through.

[0064] Fourthly, embodiments of this application provide an electronic device. The electronic device includes a housing and a camera module, with the camera module disposed within the housing.

[0065] Understandably, camera modules offer better reliability and lower cost. This electronic device also offers better reliability and lower cost. Attached Figure Description

[0114] The embodiments of this application are described below with reference to the accompanying drawings. The embodiments described herein are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallel, perpendicular, and aligned, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism, perpendicularity, and alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees (°) and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees.

[0120] In the embodiments of this application, the integral molding process of two components to obtain an integrally molded structural component means that during the process of forming one of the two components, that component is connected to the other component, without the need for further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two components together.

[0121] Figure 1 This is a schematic diagram of one embodiment of the electronic device 1000 provided in this application. Figure 2 yes Figure 1 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 shown at line AA.

[0122] like Figure 1 and Figure 2As shown, 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 helmet, virtual reality (VR) glasses, or VR helmet, etc., that has a camera module 100. Figure 1 The electronic device 1000 of the illustrated embodiment is described using a mobile phone as an example.

[0123] like Figure 1 As shown, 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 can be mounted on the housing 200. The camera module 100 can be a rear-facing camera module or a front-facing camera module. It should be noted that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the accompanying drawings below. Furthermore, when the electronic device 1000 is a device of some other form, the electronic device 1000 may not include the screen 300.

[0124] 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.

[0125] 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 an integrally formed structural component with the frame 210, that is, the back cover 220 and the frame 210 are a single integral structure.

[0126] 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.

[0127] 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 that of the rear cover 2200. Figure 1 The schematic diagram shows a circle. The light-transmitting hole 2201 connects the interior of the electronic device 1000 to the exterior. Light from outside the electronic device 1000 can enter the interior through the light-transmitting hole 2201. The camera module 100 can capture the ambient light entering the interior of the electronic device 1000.

[0128] In some embodiments, housing 200 may include a light-transmitting lens 230, which is mounted on light-transmitting hole 2201 to allow light to pass through and to be dustproof and waterproof.

[0129] Understandable, Figure 1 The installation position of the camera module 100 in the illustrated embodiment of the electronic device 100 is merely illustrative, and this application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed in other locations on the electronic device 1000, such as the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can rotate, move, or be detached relative to the terminal body, and the camera module 100 may also be disposed on the auxiliary component.

[0130] Figure 3 This is a partial structural schematic diagram of one embodiment of the camera module 100 provided in this application. Figure 4 yes Figure 3 A partially exploded view of one embodiment of the camera module 100 shown.

[0131] like Figures 2 to 4 As shown, the camera module 100 may include an optical path folding element 20, a focusing lens group 30, and an image sensor 40 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 the light-transmitting hole 2201, then pass sequentially through the optical path folding element 20 and the focusing lens group 30, and finally be imaged onto the image sensor 40. Exemplarily, the optical path folding element 20, the focusing lens group 30, and the image sensor 40 can be arranged sequentially along the X-axis direction.

[0132] It is understandable that one or more reflective lenses / prisms can be additionally disposed between the optical path folding element 20 and the image sensor 40 to change the propagation path of light between the optical path folding element 20 and the image sensor 40, so that after the light is emitted from the optical path folding element 20, it can undergo one or more reflections before finally entering the image sensor 40. In this way, the overall light path of the camera module 100 is lengthened, which helps to reduce the overall module length of the camera module 100 and save internal space of the electronic device 1000.

[0133] In other embodiments, the focusing lens group 30 may also be disposed on the light-incident side of the optical path folding element 20. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting hole 2201, and then pass through the focusing lens group 30 and the optical path folding element 20 in sequence, and finally be imaged onto the image sensor 40.

[0134] For example, the image sensor 40 is a semiconductor chip, also known as a photosensitive chip. The surface of the image sensor 40 contains hundreds of thousands to millions of photodiodes, which generate electrical charges when illuminated. The image sensor 40 utilizes the photoelectric conversion function of photoelectric 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 40 can be positioned facing the focusing lens group 30. The image sensor 40 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 40 can also be a component with other structures.

[0135] For example, the image sensor 40 can be located on the image side of the focusing lens group 30. Light rays propagating from the optical path folding element 20 can reach the image sensor 40 after passing through the focusing lens group 30, thereby achieving imaging.

[0136] In other embodiments, the camera module 100 may also include a filter (not shown). The filter can be used to filter out unwanted wavelengths of light, preventing the image sensor 40 from producing false colors or ripples, thereby improving its effective resolution and color reproduction. For example, the filter may be an infrared filter. In some other embodiments, the camera module 100 may also omit the separate filter structure and instead achieve the filtering function by surface or material treatment of some optical elements in the optical path folding element 20 and the focusing lens group 30. This application does not strictly limit the specific embodiments of the structures or components used to achieve the filtering function.

[0137] In some embodiments, the camera module 100 may further include a motor 10. The optical path folding element 20 and the focusing lens group 30 may both be mounted on the motor 10. Exemplarily, the motor 10 may have a light inlet 1001 and a light outlet 1002. Light can propagate into the motor 10 along a first direction Z through the light inlet 1001, and after reflection by the optical path folding element 20, the light can propagate out of the motor 10 along a second direction X. The motor 10 can be used to drive the optical path folding element 20 to rotate around the second direction and / or a third direction to achieve optical image stabilization (OIS) of the camera module 100, improving the imaging quality of the camera module 100. The third direction is perpendicular to the first direction and perpendicular to the second direction. Exemplarily, the motor 10 can drive the optical path folding element 20 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.

[0138] For example, the optical path folding element 20 can be a reflecting prism or a mirror. This application does not limit the specific form of the optical path folding element 20.

[0139] In some embodiments, the camera module 100 may further include a first lens 50. The first lens 50 may be fixed to the light-inlet side of the optical path folding element 20. The first lens 50 may be fixedly connected to the optical path folding element 20 by means of bonding or other methods. The first lens 50 may be a lens with positive optical power. In this way, the first lens 50 can have a light-gathering effect, allowing as much external light as possible to enter the optical path folding element 20, thereby increasing the overall light intake of the optical path folding element 20 and improving the light intake of subsequent focusing components. In other embodiments, the first lens 50 and the optical path folding element 20 may also be fixedly connected by other structural components. In other embodiments, the first lens 50 and the optical path folding element 20 may be integrally formed structural components.

[0140] In some embodiments, the camera module 100 may further include a second lens 60. The second lens 60 may be located on the light-emitting side of the optical path folding element 20. The second lens 60 may be fixedly connected to the optical path folding element 20 by means of bonding or other methods. The second lens 60 may be a lens with negative optical power. In this way, the second lens 60 has a diffusing effect, which can diffuse as much light emitted from the optical path folding element 20 as possible, thereby increasing the amount of light emitted and thus improving the amount of light received subsequently.

[0141] In some embodiments, the second lens 60 and the optical path folding element 20 can be integrally formed structural components. In other embodiments, the second lens 60 and the optical path folding element 20 can also be fixedly connected by binding with other structural components.

[0142] Understandably, compared to a camera module 100 that uses an additional reflecting prism between the focusing lens group 30 and the image sensor 40 to control the displacement of the image sensor 40 for optical image stabilization, the module size is larger. In this embodiment, the camera module 100 achieves optical image stabilization by using a motor 10 to drive the optical path folding element 20 to rotate around a first axis R1 and / or to drive the optical path folding element 20 to rotate around a second axis R2. This eliminates the need for an additional prism between the focusing assembly and the image sensor 40, 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 uses a motor 10 to control the optical path folding element 20 to rotate around the first axis R1 and / or the second axis R2 for image stabilization, which can achieve high image stabilization accuracy and good image quality.

[0143] In other embodiments, the motor 10 may also control the optical path folding element 20 to rotate only about the first axis R1.

[0144] In some implementations, motor 10 can be used to drive focusing lens group 30 to move along the optical axis for autofocus (AF). It is understood that by having motor 10 drive focusing lens group 30 to focus, camera module 100 can achieve better image quality.

[0145] In some embodiments, the camera module 100 may further include a fixed-focus lens group 70. The fixed-focus lens group 70 may be fixed to the motor 10. It is understood that the number of fixed-focus lenses 701 included in the focusing lens group 30 may be one or more. For example, Figure 2 and Figure 4 The diagram illustrates that the fixed-focus lens group 70 includes two fixed-focus lenses 701, which are located on the light-incident side and the light-outcident side of the focusing lens group 30, respectively, along the optical axis.

[0146] In some embodiments, the camera module 100 may further include a housing 9. The housing 9 may be fixedly connected to the motor 10 and is used to protect the motor 10, the optical path folding element 20, the focusing lens group 30, and the fixed-focus lens group 70.

[0147] It is understood that the motor 10 of this application can be used to drive the optical path folding element 20 for image stabilization and to drive the focusing lens group 30 for focusing. The structure of the electronic device 1000 and the camera module 100 have been described in detail above. The structure of the motor 10 in several camera modules 100 will be described in detail below with reference to the relevant figures.

[0148] Figure 5 yes Figure 4 The diagram shows a partially exploded view of one embodiment of the motor 10. It should be understood that in this embodiment, the width direction of the motor 10, which is also the width direction of the electronic device 1000, is the X-axis direction. The length direction of the motor 10, which is also the length direction of the electronic device 1000, is the Y-axis direction. The thickness direction of the motor 10, which is also the thickness direction of the electronic device 1000, is the Z-axis direction. In other embodiments, the coordinate system of the motor 10 can be flexibly set according to specific practical needs.

[0149] like Figure 4 and Figure 5 As shown, the motor 10 may include a base 1, an image stabilization bracket 2, an image stabilization drive mechanism 3, a positioning ball 4, a support member 51, a focusing bracket 6, a focusing drive mechanism 7, a first guide rod 81, and a focusing ball 82. The image stabilization bracket 2 and the focusing bracket 6 are both movably connected to the base 1. The image stabilization drive mechanism 3 drives the image stabilization bracket 2 to move relative to the base 1, and the focusing drive mechanism 7 drives the focusing bracket 6 to move relative to the base 1. The positioning ball 4 and the support member 51 are movably connected between the image stabilization bracket 2 and the base 1. The focusing bracket 6 moves relative to the base 1 in a second direction through the cooperation of the first guide rod 81 and the focusing ball 82. The following will describe several implementation methods of the operation of the various components of the motor 10 with reference to the accompanying drawings.

[0150] In some embodiments, the image stabilization bracket 2 may include a first image stabilization bracket 21 and a second image stabilization bracket 22. The second image stabilization bracket 22 can be used to support the optical path folding element 20. The first image stabilization bracket 21 is movably connected to the second image stabilization bracket 22 and the base 1. The second image stabilization bracket 22, carrying the optical path folding element 20, can rotate relative to the first image stabilization bracket 21 about a second axis R2, and the first image stabilization bracket 21 can rotate relative to the base 1 about a first axis R1. In other embodiments, the image stabilization bracket 2 may only include the first image stabilization bracket 21, which can also support the optical path folding element 20. The first image stabilization bracket 21, carrying the optical path folding element 20, can rotate relative to the base 1 about a first axis R1.

[0151] In some embodiments, when the image stabilization bracket 2 includes a first image stabilization bracket 21 and a second image stabilization bracket 22, the motor 10 may further include a support member 52. The second image stabilization bracket 22 can be movably connected to the first image stabilization bracket 21 via the support member 52. Exemplarily, the support member 52 may include a first support member 521 and a second support member 522. The image stabilization drive mechanism 3 can be used to drive the first image stabilization bracket 21 to rotate relative to the base 1 about a first axis R1, and can also be used to drive the second image stabilization bracket 22 to rotate relative to the base 1 about a second axis R2.

[0152] In some embodiments, the support member 51 may include a first support member 511 and a second support member 512.

[0153] In some embodiments, the image stabilization drive mechanism 3 can employ a moving coil or moving magnet drive method, which is technologically mature and has low implementation cost. For example, the image stabilization drive mechanism 3 may include a first coil 31, a first magnetic element 32, a second coil 33, a second magnetic element 34, a third coil 35, and a third magnetic element 36. In other embodiments, the image stabilization drive mechanism 3 may also include more or fewer structures; for example, the image stabilization drive mechanism 3 may also include a magnetic conductor (not shown in the figures).

[0154] It is understood that the number of the first coil 31, the number of the second coil 33, and the number of the third coil 35 are not limited to those specified in the appendix. Figure 8 One of the embodiments is shown. In other embodiments, there may be multiple first coils 31 and multiple first magnetic elements 32, and multiple first coils 31 and multiple first magnetic elements 32 may be arranged in a one-to-one correspondence.

[0155] In other embodiments, the anti-shake drive mechanism 3 may also omit the second coil 33 and the second magnetic element 34.

[0156] In other embodiments, the anti-shake drive mechanism 3 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.

[0157] In some embodiments, the focusing drive mechanism 7 can employ a moving coil or moving magnet drive method, which is technologically mature and has low implementation cost. For example, the focusing drive mechanism 7 may include a fourth coil 71, a fourth magnetic element 72, a fifth coil 73, and a fifth magnetic element 74. In other embodiments, the focusing drive mechanism 7 may include more or fewer structures; for example, the focusing drive mechanism 7 may also include a magnetic conductor.

[0158] It is understandable that the number of fourth coils 71 and the number of fifth coils 73 may not be limited to the attached ones. Figure 8One of the embodiments is shown. In other embodiments, the number of fourth coils 71 and the number of fifth coils 73 can be multiple.

[0159] In other embodiments, the focusing drive mechanism 7 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.

[0160] Figure 6 yes Figure 5 The diagram shows a structural schematic of one embodiment of the base 1 shown. Figure 7 yes Figure 6 The diagram shows the structure of base 1 from another angle.

[0161] like Figure 6 and Figure 7 As shown, the base 1 may include a base plate 11, a back plate 12, a first fixing post 13, a second fixing post 14, a third fixing post 15, a fourth fixing post 16, a first side plate 17, and a second side plate 18. The back plate 12, the first fixing post 13, the second fixing post 14, the third fixing post 15, the fourth fixing post 16, the first side plate 17, and the second side plate 18 may be located on the same side of the base plate 11 and are fixedly connected to the base plate 11.

[0162] Exemplarily, the base plate 11 may include a first plate portion 111 and a second plate portion 112. The first plate portion 111 and the second plate portion 112 may be connected along a second direction. A first side plate 17 and a second side plate 18 may be arranged opposite to each other and spaced apart, and the first side plate 17 and the second side plate 18 may be arranged along a third direction. A back plate 12, the first side plate 17, and the second side plate 18 may be connected to the first plate portion 111. The back plate 12 may be arranged along the second direction with the first side plate 17 and the second side plate 18. The back plate 12 may be connected between the first side plate 17 and the second side plate 18. A first fixing post 13, a second fixing post 14, a third fixing post 15, and a fourth fixing post 16 may be connected to the second plate portion 112. The first fixing post 13 and the second fixing post 14 may be spaced apart along the second direction. The third fixing post 15 and the fourth fixing post 16 may be spaced apart along the second direction. The first fixing post 13 and the fourth fixing post 16 may be arranged along a third direction and connected to both sides of the second plate portion 112. The second fixing post 14 and the third fixing post 15 can be arranged along a third direction and connected to both sides of the second plate 112.

[0163] It is understood that the base 1 can be used to simultaneously mount the image stabilization bracket 2 and the focusing bracket 6. In some embodiments, the base 1 may include a first support portion 104 and a second support portion 105. Figure 7The positions of the first support portion 104 and the second support portion 105 are roughly indicated by dashed boxes. The first support portion 104 and the second support portion 105 can be arranged in a second direction and are integrally formed structural components. For example, when the base 1 includes a first plate portion 111, a second plate portion 112, a back plate 12, a first fixing post 13, a second fixing post 14, a third fixing post 15, and a fourth fixing post 16, the first plate portion 111 and the back plate 12 can be used to constitute the first support portion 104, and the second plate portion 112, the first fixing post 13, the second fixing post 14, the third fixing post 15, and the fourth fixing post 16 can be used to constitute the second support portion 105. Furthermore, when the base 1 also includes a first side plate 17 and a second side plate 18, the first side plate 17 and the second side plate 18 can be used together with the first plate portion 111 and the back plate 12 to constitute the first support portion 104. When the base 1 is used for the motor 10, the first support portion 104 can be used to mount the first image stabilization bracket 21 and the second image stabilization bracket 22, and the second support portion 105 can be used to mount the focusing bracket 6. It is understood that when the base 1 is used to support the focusing bracket 6 and the first image stabilization bracket 21, the focusing bracket 6 and the first image stabilization bracket 21 are respectively mounted at different positions on the base plate 11, and the first fixing post 13 and the fourth fixing post 16 are used to separate the two and reduce the risk of interference.

[0164] For example, the first plate 111, back plate 12, first fixing post 13, fourth fixing post 16, first side plate 17, and second side plate 18 can enclose a first mounting space 101, which can be used to accommodate structural components such as the image stabilization bracket 2. The second plate 112, first fixing post 13, second fixing post 14, third fixing post 15, and fourth fixing post 16 can enclose a second mounting space 102, which can be used to accommodate structural components such as the focusing bracket 6. The first fixing post 13, second fixing post 14, third fixing post 15, and fourth fixing post 16 can be used to limit the movement of the focusing bracket 6, preventing it from exceeding its travel range during movement and interfering with the first image stabilization bracket 21. The first mounting space 101 connects to the second mounting space 102 to allow light to pass through.

[0165] In some embodiments, the light inlet 1001 and light outlet 1002 of the motor 10 can be located on the base 1. Exemplarily, the ends of the back plate 12, the first side plate 17, the second side plate 18, the first fixing post 13, and the fourth fixing post 16 that are away from the base plate 11 can be used to enclose the light inlet 1001, which communicates with the first mounting space 101. The ends of the first fixing post 13, the second fixing post 14, the third fixing post 15, and the fourth fixing post 16 that are away from the base plate 11 can be used to enclose the light outlet 1002, which communicates with the second mounting space 102. Light can propagate into the base 1 through the light inlet 1001 in a first direction, and light can propagate out of the base 1 through the light outlet 1002 in a second direction.

[0166] It is understood that, in order to facilitate the description of the specific structure and shape of the base 1, the base 1 is described in multiple parts in this embodiment. However, this does not affect the fact that the multiple parts of the base 1 can be integrally formed structural components, that is, the base plate 11, back plate 12, first fixing post 13, second fixing post 14, third fixing post 15, fourth fixing post 16, first side plate 17 and second side plate 18 can be integrally formed structural components.

[0167] In some embodiments, the first support portion 104 of the base 1 may be provided with a positioning groove 103. The positioning groove 103 may be used to accommodate the positioning ball 4. Exemplarily, the positioning groove 103 may be located on the back plate 12 of the base 1, and the opening of the positioning groove 103 may face the first mounting space 101.

[0168] In some embodiments, the first plate portion 111 of the base plate 11 may be provided with a first clearance hole 1111. The first clearance hole 1111 can penetrate the base plate 11 in a first direction Z. The second side plate 18 may be provided with a second clearance hole 181. The second clearance hole 181 can penetrate the second side plate 18 in a third direction Y. The first clearance hole 1111 can be used to accommodate a portion of the anti-shake drive mechanism 3. The second clearance hole 181 can be used to accommodate a portion of the anti-shake drive mechanism 3.

[0169] For example, the first side plate 17 may be provided with a first mounting groove 171. The opening of the first mounting groove 171 may face the second side plate 18. The first mounting groove 171 may be used to accommodate part of the anti-shake drive mechanism 3.

[0170] In some embodiments, the base plate 11 may further include a third plate portion 113. In a second direction, the third plate portion 113 may be located between the first plate portion 111 and the second plate portion 112. The third plate portion 113 may be fixedly connected to the first plate portion 111. The third plate portion 113 is used to support the fixed-focus lens group 70. Exemplarily, in a third direction, the third plate portion 113 may be located between the first fixing post 13 and the fourth fixing post 16.

[0171] In some embodiments, the base plate 11 may further include a fourth plate portion 114. In a second direction, the fourth plate portion 114 may be located on the side of the second plate portion 112 away from the third plate portion 113. The fourth plate portion 114 may be fixedly connected to the second plate portion 112. The fourth plate portion 114 is used to support the fixed-focus lens group 70. Exemplarily, in a third direction, the fourth plate portion 114 may be located between the second fixing post 14 and the third fixing post 15.

[0172] It is understood that the base plate 11 can selectively be provided with a third plate portion 113 and a fourth plate portion 114, thereby enabling it to support multiple fixed-focus lenses 701. The third plate portion 113 and the fourth plate portion 114 can be structural components integrally formed with the first plate portion 111 and the second plate portion 112 (e.g., Figure 6 and Figure 7 (As shown), or the third plate portion 113 and the fourth plate portion 114 can also be detachable structural components. When the third plate portion 113 and the fourth plate portion 114 can be structural components integrally formed with the first plate portion 111 and the second plate portion 112, it is beneficial to simplify the assembly process of the motor 10, and the connection reliability between the various parts of the base 1 is better.

[0173] Figure 8 yes Figure 5 The diagram shows a structural schematic of one embodiment of the first image stabilization bracket 21 shown. Figure 9 yes Figure 8 The first image stabilization bracket 21 shown is a structural schematic diagram from another angle.

[0174] like Figure 8 and Figure 9 As shown, the first image stabilization bracket 21 includes a first arm 211, a second arm 212, and a connecting arm 213. Exemplarily, the first arm 211 and the second arm 212 can be arranged opposite each other and spaced apart, and the connecting arm 213 can be fixedly connected between the first arm 211 and the second arm 212. The arrangement direction of the first arm 211 and the second arm 212 can be parallel to a third direction Y.

[0175] It is understood that, for ease of describing the basic structure and shape of the first image stabilization bracket 21, this embodiment describes the first image stabilization bracket 21 in three parts. However, this does not affect the fact that the first image stabilization bracket 21 can be a one-piece molded structural component, that is, the first arm 211, the second arm 212, and the connecting arm 213 can be a one-piece molded structural component. In other embodiments, the first image stabilization bracket 21 can also be formed by different independent structural components through an assembly process. For example, the first arm 211 and the second arm 212 of the first image stabilization bracket 21 can be independent structural components and are fixedly connected to the connecting arm 213 by means of adhesive bonding, welding, etc.

[0176] For example, the connecting arm 213 may include a first surface 2131 and a second surface 2132. The first surface 2131 and the second surface 2132 may be arranged opposite to each other along a second direction. The first arm 211 and the second arm 212 may be fixedly connected to the first surface 2131 of the connecting arm 213.

[0177] For example, the first arm 211 may be provided with a second groove 2111. The opening of the second groove 2111 may face away from the second arm 212. The second groove 2111 may be used to accommodate part of the anti-shake drive mechanism 3.

[0178] Exemplarily, the first support arm 211 may be provided with a first limiting groove 2112. The opening of the first limiting groove 2112 may be located on the top surface of the first support arm 211. In some embodiments, the first limiting groove 2112 may be a conical groove. Exemplarily, the first limiting groove 2112 may include three second limiting surfaces 2110, which are arranged in a generally triangular pyramid shape, that is, the three second limiting surfaces 2110 constitute the three sides of a triangular pyramid. The first limiting groove 2112 may be used to accommodate part of the first support member 521.

[0179] For example, the second arm 212 may be provided with a third groove 2121. The opening of the third groove 2121 may face away from the first arm 211. The third groove 2121 may be used to accommodate part of the anti-shake drive mechanism 3.

[0180] For example, the second support arm 212 may be provided with a second limiting groove 2122. The opening of the second limiting groove 2122 may be located on the top surface of the second support arm 212. The second limiting groove 2122 may be used to accommodate part of the second support member 522.

[0181] In some embodiments, the connecting arm 213 may be provided with a fixing groove 2133, a first rolling groove 2134, and a second rolling groove 2135. The openings of the fixing groove 2133, the first rolling groove 2134, and the second rolling groove 2135 may all be located on the second surface 2132 of the connecting arm 213. The fixing groove 2133, the first rolling groove 2134, and the second rolling groove 2135 are spaced apart. Exemplarily, the first rolling groove 2134 and the second rolling groove 2135 may be arranged spaced apart along a third direction upward. The fixing groove 2133 may be used to accommodate a portion of the positioning ball 4. The first rolling groove 2134 may be used to accommodate a portion of the first support member 511. The second rolling groove 2135 may be used to accommodate a portion of the second support member 512.

[0182] For example, the connecting arm 213 may be provided with a third mounting groove 2136 and a fourth mounting groove 2137. The openings of the third mounting groove 2136 and the fourth mounting groove 2137 may both be located on the second surface 2132 of the connecting arm 213. The fixing groove 2133, the first rolling groove 2134, the second rolling groove 2135, the third mounting groove 2136, and the fourth mounting groove 2137 are arranged at intervals.

[0183] Figure 10 yes Figure 4 A partial structural schematic diagram of one embodiment of the motor 10 shown. Figure 11A yes Figure 10 The structure shown is a partial cross-sectional view of one embodiment at BB from another angle. Figure 11B yes Figure 10 The structure shown is a partial cross-sectional view of one embodiment at CC from another angle. Figure 12 yes Figure 10 The structure shown is a partial cross-sectional view of one embodiment at DD from another angle.

[0184] like Figures 10 to 12 As shown, the first image stabilization bracket 21 is movably connected to the base 1. The first image stabilization bracket 21 can be located in the first mounting space 101 of the base 1. Exemplarily, the positioning ball 4 can be movably connected between the first image stabilization bracket 21 and the base 1. Exemplarily, along a third upward direction, the first arm 211 of the first image stabilization bracket 21 can be disposed opposite to the first side plate 17 of the base 1. The second arm 212 of the first image stabilization bracket 21 can be disposed opposite to the second side plate 18 of the base 1. Along the direction of the first axis R1, the connecting arm 213 of the first image stabilization bracket 21 can be disposed opposite to the back plate 12 of the base 1. The positioning ball 4 can be movably connected between the connecting arm 213 and the back plate 12 of the base 1.

[0185] In one embodiment, the first anti-shake bracket 21 can be movably connected to the base 1 via the positioning ball 4, the first support member 511, and the second support member 512.

[0186] In one embodiment, the positioning ball 4 is movably connected to the positioning groove 103 of the back plate 12. The groove surface of the positioning groove 103 includes three limiting surfaces 1031, which form the three sides of a triangular pyramid. The positioning ball 4 and the positioning groove 103 are arranged along a second direction. The positioning ball 4 is movably connected to the positioning groove 103 and simultaneously contacts the three limiting surfaces 1031. The first shaft R1 passes through the center of the space enclosed by the three limiting surfaces 1031. It can be understood that this application achieves the positioning of the first shaft R1 through the cooperation of the positioning ball 4 and the positioning groove 103, so that when the first anti-shake bracket 21 is movably connected to the base 1, it can rotate around the first shaft R1. The positioning ball 4 and positioning groove 103 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 has a small contact area, resulting in less friction between the first anti-shake bracket 21 and the base 1. This reduces the likelihood of jamming when the first anti-shake bracket 21 moves relative to the base 1, and allows for higher control accuracy of the motor 10. When the motor 10 is used in the camera module 100, the imaging quality of the camera module 100 is better. In addition, when the positioning ball 4 is connected within the positioning groove 103, there are always three contact points at any given time, providing better limiting and support for the positioning ball 4.

[0187] It is understood that adjacent limiting surfaces 1031 can be directly connected or indirectly connected. The positioning groove 103 can be a conical groove, a rectangular groove, or other polygonal groove. This application does not impose any restrictions.

[0188] In one embodiment, the backplate 12 may include a metal insert 121. The metal insert 121 may be recessed in a direction away from the first image stabilization bracket 21 to form a positioning groove 103. Positioning balls 4 may be tactilely connected to the metal insert 121 of the backplate 12. This helps to reduce the kinetic friction between the positioning balls 4 and the metal insert 121 of the backplate 12, thereby helping to reduce the kinetic friction between the base 1 and the first image stabilization bracket 21. In addition, the metal insert 121 is made of metal, which has a lower coefficient of friction than the positioning balls 4 directly rubbing against plastic. Tactilely connecting the positioning balls 4 to the metal insert 121 further helps to reduce the kinetic friction between the first image stabilization bracket 21 and the base 1. In other embodiments, the positioning balls 4 may be slidably connected to the metal insert 121 of the backplate 12.

[0189] In one embodiment, along the second direction, the gap D1 between the first anti-shake bracket 21 and the base 1, the radius R of the positioning ball 4, and the depth D2 of the positioning ball 4 in the positioning groove 103 satisfy the following relationship: 0 < D1 < (2R - D2). In this way, while satisfying the reliability and motion stability of the positioning ball 4 in the positioning groove 103, the base 1 and the first anti-shake bracket 21 are minimized in motion interference.

[0190] In one embodiment, the radius R of the positioning ball 4 and the depth D2 of the positioning ball 4 in the positioning groove 103 satisfy the following relationship: 0.01R≤D2≤0.9R. In this way, the contact depth between the positioning ball 4 and the positioning groove 103 can be within a suitable range, ensuring that the positioning ball 4 can be stably placed in the positioning groove 103 during movement and is not easily dislodged during the process of contact.

[0191] In one embodiment, the included angles between the three limiting surfaces 1031 and the first shaft R1 are equal. For example, two adjacent limiting surfaces 1031 are arranged at a 60° angle, and the limiting surfaces 1031 and the first shaft R1 are also arranged at a 60° angle. This results in a more regular shape for the positioning groove 103, reducing design and manufacturing complexity.

[0192] In one embodiment, the positioning ball 4 is fixedly connected to the first anti-shake bracket 21. In this way, the connection strength between the positioning ball 4 and the first anti-shake bracket 21 is better, the position of the positioning ball 4 relative to the first anti-shake bracket 21 is not easy to move, the interference of the positioning ball 4 is smaller when the motor 10 detects the position of the first anti-shake bracket 21 relative to the base 1, and the control accuracy of the motor 10 is better.

[0193] In one embodiment, the positioning ball 4 can also be movably connected to the first anti-shake bracket 21. This reduces the risk of the positioning ball 4 getting stuck.

[0194] In some embodiments, the motor 10 may further include a shim 53. The shim 53 can be fixedly connected to the base 1. Along the second direction, the shim 53 can be disposed opposite to the anti-shake bracket 2. The shim 53 is located between the anti-shake bracket 2 and the base 1. It is understood that during the assembly of the motor 10, the anti-shake bracket 2 (first anti-shake bracket 21) is installed first, and then the shim 53 is installed. On the one hand, when the shim 53 is not installed, the space for installing the anti-shake bracket 2 is larger, the installation difficulty of the anti-shake bracket 2 (first anti-shake bracket 21) is lower, and the anti-shake bracket 2 is less likely to collide with surrounding components during the installation process; on the other hand, after the installation of the anti-shake bracket 2 (first anti-shake bracket 21) is completed, the shims 53 are respectively installed on the base 1, which can reduce the gap of the anti-shake bracket 2 (first anti-shake bracket 21) facing the first fixed post 13, that is, it can reduce the gap between the anti-shake bracket 2 and the base 1, and the reliability of the motor 10 is better. For example, when the motor 10 is hit or dropped, the movement distance of the anti-shake bracket 2 (first anti-shake bracket 21) is small, the offset of the anti-shake bracket 2 (first anti-shake bracket 21) is small, or the impact between the anti-shake bracket 2 (first anti-shake bracket 21) and the surrounding devices is small.

[0195] Exemplarily, the gasket 53 can be located within the first mounting space 101, and along the second direction, the gasket 53 can be disposed opposite to the first image stabilization bracket 21. Exemplarily, there can be two gaskets 53, namely a first gasket 531 and a second gasket 532. The first gasket 531 and the second gasket 532 can be spaced apart along the third direction, the first gasket 531 can be fixedly connected to the first fixing post 13, and the second gasket 532 can be fixedly connected to the fourth fixing post 16. Along the second direction, one first gasket 531 can be disposed opposite to the first arm 211 of the first image stabilization bracket 21, and the second gasket 532 can be disposed opposite to the second arm 212 of the first image stabilization bracket 21. In other words, along the second direction, the first gasket 531 is located between the first arm 211 and the base 1, and the second gasket 532 can be located between the second arm 212 and the base 1.

[0196] It is understood that the first shim 531 and the second shim 532 are respectively disposed opposite to the two sides of the first image stabilization bracket 21, reducing the gap between the first image stabilization bracket 21 and the base 1 from multiple positions, thereby further improving the reliability of the motor 10. The number of shims 53 can be set according to needs, and is not limited to the two exemplified in this application. Furthermore, the position of the shims 53 can also be adaptively adjusted according to actual conditions, and can be used to reduce the gap at any position around the first image stabilization bracket 21.

[0197] In some embodiments, the gasket 53 may be flexible. When the gasket 53 is mounted on the base 1, the gasket 53 protrudes from the base 1 in a second direction. For example, the material of the gasket 53 may include silicone or foam. It is understood that when the gasket 53 is flexible, it is beneficial to reduce abnormal noise from the motor 10. For example, when the motor 10 is impacted or dropped, the anti-shake bracket 2 collides with the gasket 53 first, and the noise generated during the collision between the anti-shake bracket 2 and the gasket 53 is relatively small. For example, as... Figure 11B As shown, the gasket 53 may include a flexible portion 533 and a rigid portion 534. The rigid portion 534 is embedded within the flexible portion 533. The flexible portion 533 provides flexibility, and the rigid portion 534 provides support. The rigid portion 534 is made of a material with a higher hardness than the flexible portion 533. For example, the flexible portion 533 may be made of silicone or foam, and the rigid portion 534 may be made of metal or plastic. In other embodiments, the gasket 53 may also be made entirely of a material with higher hardness.

[0198] In some embodiments, the gasket 53 can be fixedly connected to the base 1 by means of adhesive bonding, welding or other methods; or the gasket 53 can be positioned on the base 1 first by means of concave-convex fit or through hole and columnar structure fit, and then fixedly connected by adhesive bonding or welding.

[0199] In one embodiment, the motor 10 may further include a first sensor 541 and a first detection magnet 542. Along a direction parallel to the second direction, the first sensor 541 and the first detection magnet 542 may be disposed opposite each other. The first sensor 541 can be used to detect the magnetic field of the first detection magnet 542 to achieve displacement detection of the first image stabilization bracket 21 relative to the base 1 in the YZ plane. It is understood that the figures illustrate that the first sensor 541 is fixed to the base 1, and the first detection magnet 542 is fixed to the first image stabilization bracket 21. In other embodiments, the first sensor 541 may also be fixed to the first image stabilization bracket 21, and the first detection magnet 542 may be fixed to the base 1.

[0200] In other embodiments, the first sensor 541 may be positioned opposite the first detection magnet 542 in a direction parallel to a third direction. The first sensor 541 may also detect the displacement of the first stabilization bracket 21 relative to the base 1 in the YZ plane.

[0201] Figure 13 yes Figure 10 The structure shown is a partial cross-sectional view of one embodiment at EE from another angle.

[0202] like Figure 13As shown, the first support member 511 can be movably connected between the base 1 and the first image stabilization bracket 21. The first support member 511 can be used for the support connection between the base 1 and the first image stabilization bracket 21. By setting the first support member 511, the connection area between the base 1 and the first image stabilization bracket 21 can be increased, which is beneficial to the stable connection between the first image stabilization bracket 21 and the base 1. For example, the first support member 511 can be rolled between the base 1 and the first image stabilization bracket 21. In this way, compared with the first support member 511 slidingly connected between the base 1 and the first image stabilization bracket 21, the first support member 511 rollingly connected between the base 1 and the first image stabilization bracket 21 is beneficial to reducing the friction between the first support member 511 and the base 1 and the first image stabilization bracket 21, thereby reducing the motion friction between the first image stabilization bracket 21 and the base 1.

[0203] For example, the first support member 511 can be roll-connected between the metal insert 121 of the back plate 12 of the base 1 and the connecting arm 213 of the first image stabilization bracket 21. In this way, the first support member 511 can be roll-connected to the metal insert 121, and the coefficient of friction of the metal insert 121 is smaller than that of plastic, which helps to reduce the kinetic friction between the first support member 511 and the back plate 12, thereby helping to reduce the kinetic friction between the first image stabilization bracket 21 and the base 1.

[0204] In other embodiments, the first support member 511 may also be slidably connected between the base 1 and the first anti-shake bracket 21. This application does not limit the specific implementation of the first support member 511 being movably connected between the base 1 and the first anti-shake bracket 21.

[0205] In one embodiment, the back plate 12 of the base 1 may be provided with a first support groove 122. The opening of the first support groove 122 may face the first anti-shake bracket 21. The first support member 511 may be rollably connected to the first support groove 122 of the back plate 12 of the base 1 and the first rolling groove 2134 of the connecting arm 213 of the first anti-shake bracket 21. A portion of the first support member 511 is located in the first rolling groove 2134, and a portion is located in the first support groove 122.

[0206] It is understood that the first bearing groove 122 and the first rolling groove 2134 can be used to limit the first bearing member 511. When the first bearing member 511 is movably connected between the base 1 and the first anti-shake bracket 21, the first bearing groove 122 and the first rolling groove 2134 can be used to prevent the first bearing member 511 from detaching from the base 1 or the first anti-shake bracket 21. Those skilled in the art can selectively set one or more of the first bearing groove 122 and the first rolling groove 2134 according to their needs, and this application does not impose any restrictions. When only one of the first bearing groove 122 and the first rolling groove 2134 is selected for limiting the first bearing member 511, the other can adopt a planar structure for contact.

[0207] For example, the first support member 511 may be a ball or a roller, etc. This application does not limit the shape of the first support member 511. When the first support member 511 is a ball, compared with the scheme where the first support member 511 is a roller, the connection area between the ball and the base 1 and the first anti-shake bracket 21 can be smaller than that of the roller, which is beneficial to reduce the motion friction between the first support member 511 and the base 1 and the first anti-shake bracket 21.

[0208] In some embodiments, the first bearing member 511 may include one or more balls. When there are multiple balls, the bearing area between the first bearing member 511 and the base 1 can be larger, and the bearing area between the first image stabilization bracket 21 and the base 1 can be larger, which helps to reduce the risk of reliability issues in the bearing area between the first image stabilization bracket 21 and the base 1. For example, the first bearing member 511 may include three balls.

[0209] It is understood that when there are multiple first bearing members 511, the shape and size of the multiple first bearing members 511 can be set to be the same or different, and this application does not impose any restrictions.

[0210] In other embodiments, the first support member 511 may also be fixedly connected to the first anti-shake bracket 21 and slidably connected to the base 1. Alternatively, the first support member 511 may be fixedly connected to the base 1 and slidably connected to the first anti-shake bracket 21.

[0211] In one embodiment, the second support member 512 is movably connected to the second support groove 123 of the back plate 12 of the base 1 and the second rolling groove 2135 of the connecting arm 213 of the first anti-shake bracket 21. It is understood that the arrangement of the second support member 512 with the first anti-shake bracket 21 and the base 1 can refer to the arrangement of the first support member 511 with the first anti-shake bracket 21 and the base 1, and will not be described again here.

[0212] In some embodiments, the positioning ball 4, the first support member 511, and the second support member 512 are spaced apart. The line connecting the positions of the positioning ball 4, the first support member 511, and the second support member 512 can form a triangle, thus making the support between the first anti-shake bracket 21 and the base 1 more stable. In other embodiments, more support members 51 can be provided between the first anti-shake bracket 21 and the base 1.

[0213] In some implementations, one of the first support member 511 and the second support member 512 may be selectively provided.

[0214] In some embodiments, the motor 10 may further include a first magnetic member 55. The first magnetic member 55 may be fixedly connected to the first image stabilization bracket 21. The first magnetic member 55 may be disposed opposite to the metal insert 121 in a direction parallel to the second direction. The first magnetic member 55 may interact with the metal insert 121 to provide a magnetic force parallel to the second direction, so that the first image stabilization bracket 21 and the base 1 can be stably supported in the second direction. Exemplarily, the first magnetic member 55 may be a magnet or other magnetic component.

[0215] It is understood that the first magnetic attractor 55 in this embodiment can be made of a magnetic material, and the first magnetic attractor 55 cooperates with the metal insert 121 to provide magnetic attraction. In other embodiments, the first magnetic attractor 55 can also be made of a magnetically conductive material (e.g., metal), and the motor 10 can be further provided with a magnetic component, which cooperates with the first magnetic attractor 55 to provide magnetic attraction parallel to the second direction.

[0216] In some implementations, such as Figures 11A to 13As shown, one of the first coil 31 and the first magnetic element 32 is disposed on the first arm 211 of the first image stabilization bracket 21, and the other is disposed on the base 1. One of the second coil 33 and the second magnetic element 34 is disposed on the second arm 212 of the first image stabilization bracket 21, and the other is disposed on the base 1. The first coil 31 faces the first magnetic element 32 in a direction parallel to the third direction. "The first coil 31 facing the first magnetic element 32" means that the winding plane of the first coil 31 faces the first magnetic element 32. This interpretation applies to all subsequent uses of "facing" and will not be elaborated further. When the first coil 31 is energized, the first magnetic element 32 can cooperate with the first coil 31, and the first arm 211 of the first image stabilization bracket 21 receives a driving force parallel to the first direction, which drives the first image stabilization bracket 21 to rotate relative to the first support portion 104 around the first axis R1. The second coil 33 faces the second magnetic element 34 in a direction parallel to the third direction. After the second coil 33 is energized, the second magnetic component 34 can cooperate with the second coil 33, and the second arm 212 of the first image stabilization bracket 21 receives a driving force parallel to the first direction, which drives the first image stabilization bracket 21 to rotate relative to the first support part 104 around the first axis R1. When the first arm 211 and the second arm 212 of the first image stabilization bracket 21 are simultaneously subjected to force, the resultant force on the two arms can be parallel to the first direction. The positioning ball 4 is limited by the groove surface in the positioning groove 103, restricting the translation of the first image stabilization bracket 21 in the YZ plane. Under the limiting effect of the positioning groove 103 on the positioning ball 4, the first image stabilization bracket 21 can rotate around the first axis R1.

[0217] The forces acting on the first arm 211 and the second arm 212 can be in the same direction or in opposite directions. When the forces on the first arm 211 and the second arm 212 are in the same direction, they are not equal, resulting in an imbalance of forces on both sides of the first image stabilization bracket 21, enabling rotation around the first axis R1. When the forces on the first arm 211 and the second arm 212 are in opposite directions, they can be equal or not equal. The forces on the first arm 211 and the forces acting on the second arm 212 simultaneously provide the first image stabilization bracket 21 with the torque required to rotate around the first axis R1, resulting in higher driving efficiency.

[0218] In other embodiments, the first coil 31 is disposed facing the first magnetic element 32 in a direction parallel to the second direction. And / or, the second coil 33 is disposed facing the second magnetic element 34 in a direction parallel to the second direction.

[0219] It is understood that this embodiment illustrates a moving magnet drive mechanism 3, with the coil fixed to the base 1 for electrical signal transmission. For example, the first magnetic element 32 is disposed on the first arm 211 of the first image stabilization bracket 21, and the first coil 31 is disposed on the base 1. The second magnetic element 34 is disposed on the second arm 212 of the first image stabilization bracket 21, and the second coil 33 is disposed on the base 1. In other embodiments, the image stabilization drive mechanism 3 may also employ a moving coil drive mechanism. The positions of the first coil 31 and the first magnetic element 32 may be interchanged. And / or, the positions of the second coil 33 and the second magnetic element 34 may be interchanged.

[0220] In some embodiments, the first coil 31 and the second coil 33 can be powered by a flexible circuit board 99 or conductive traces, or by embedding a metal component inside the base 1 to provide conductivity, thereby enabling power supply to the first coil 31 and the second coil 33. The power supply method for the first coil 31 and the second coil 33 can be selectively set according to requirements, and this application does not impose any limitations.

[0221] In some embodiments, a magnetic shielding sheet 98 may be provided on the side of the first magnetic element 32 away from the first coil 31. The magnetic shielding sheet 98 can be used to reduce the leakage magnetic field of the first magnetic element 32 on the side away from the first coil 31, which is beneficial to increasing the magnetic field strength at the location of the first coil 31 and thus improving the driving efficiency. Similarly, a magnetic shielding sheet 98 may also be provided on the side of the second magnetic element 34 away from the second coil 33 to improve the driving efficiency. Magnetic shielding sheets may also be provided near the third magnetic element 36, the fourth magnetic element 72, and the fifth magnetic element 74 in this application to improve the driving efficiency, which will not be elaborated further below.

[0222] In other embodiments, the anti-shake drive mechanism 3 may also consist of only the first coil 31 and the first magnetic element 32.

[0223] Figure 14 yes Figure 5 The diagram shows a structural schematic of one embodiment of the focusing bracket 6. Figure 15 yes Figure 14 The diagram shows the structure of the focusing bracket 6 at another angle.

[0224] like Figure 14 and Figure 15 As shown, the focusing bracket 6 may include a first branch 61, a second branch 62, and a connecting portion 63. The first branch 61 and the second branch 62 are spaced apart along a third direction upwards. The connecting portion 63 connects between the bottom of the first branch 61 and the bottom of the second branch 62, and the first branch 61, the second branch 62, and the connecting portion 63 can enclose a "U"-shaped space 601. The "U"-shaped space can be used to mount the focusing lens group 30.

[0225] In some embodiments, the second branch 62 may be provided with a second groove 621, and the opening of the second groove 621 may be located on the bottom surface of the second branch 62.

[0226] In some embodiments, the first branch 61 may be provided with a fourth groove 612, the opening of which may be located on the outer side 613 of the first branch 61. The outer side 613 of the first branch 61 faces away from the "U"-shaped space 601. The second branch 62 may be provided with a fifth groove 622, the opening of which may be located on the outer side 623 of the second branch 62. The outer side 623 of the second branch 62 faces away from the "U"-shaped space 601.

[0227] Figure 16 yes Figure 4 The diagram shows a partial structural schematic of the motor 10 shown. Figure 17 yes Figure 16 The structure shown is a partial cross-sectional view of one embodiment at FF from another angle.

[0228] like Figure 16 and Figure 17 As shown, the focusing bracket 6 can be movably connected to the second support portion 105 of the base 1. Exemplarily, the focusing bracket 6 can be installed in the second mounting space 102 of the base 1. It is understood that, compared to conventional technical solutions, the focusing bracket 6 and the image stabilization bracket 2 of the camera module 100 are driven by two independent motors. The two motors have numerous component modules, and the assembly process for multiple motors within the camera module is numerous and complex, leading to increased component and manufacturing costs. Furthermore, when the focusing motor and the image stabilization motor are connected by adhesive, there are reliability risks such as adhesive failure and cracking. In this application, both the focusing bracket 6 and the image stabilization bracket 2 are mounted on the base 1, meaning that the focusing bracket 6 and the image stabilization bracket 2 are mounted on the same base 1, sharing the base 1. The base 1 can simultaneously support both the image stabilization bracket 2 and the focusing bracket 6. By integrating the focusing and image stabilization functions into a single motor 10, the number of components, assembly steps, and complexity of the motor 10 / camera module 100 can be reduced, thereby lowering the cost of the motor 10 / camera module 100. Furthermore, the integrated focusing and image stabilization motor 10, by sharing a single molded structural component (the first support part 104 and the second support part 105 of the base 1 are single molded structural components), reduces the reliability risks of traditional glue-bonded solutions, such as delamination and cracking.

[0229] In some embodiments, the fourth magnetic element 72 can be fixedly connected to the first branch 61 of the focusing bracket 6. The fourth magnetic element 72 can also be fixedly connected to the second branch 62 of the focusing bracket 6. Exemplarily, the fourth magnetic element 72 can be installed in the fourth groove 612 of the first branch 61. The fifth magnetic element 74 can be installed in the fifth groove 622 of the second branch 62. The fourth coil 71 and the fifth coil 73 can be fixed to the base 1. The fourth coil 71 faces the fourth magnetic element 72, and the fifth coil 73 faces the fifth magnetic element 74. When the fourth coil 71 and the fifth coil 73 are energized, they cooperate with the magnetic fields of the fourth magnetic element 72 and the fifth magnetic element 74 to generate a driving force parallel to the second direction, which drives the focusing bracket 6 to move relative to the base 1 along the second direction.

[0230] In some implementations, such as Figure 17 As shown, the fourth coil 71 and the fifth coil 73 can be electrically connected to the flexible circuit board 99 and powered through the flexible circuit board 99. Alternatively, the fourth coil 71 and the fifth coil 73 can be powered through a conductive metal or a metal component embedded in the base 1 (not shown).

[0231] In some embodiments, the fourth coil 71 and the fifth coil 73 can be directly fixed to the base 1, or the fourth coil 71 and the fifth coil 73 can be fixed to the flexible circuit board 99, which is fixedly connected to the base 1.

[0232] In some embodiments, the two ends of the first guide rod 81 are fixedly connected to the base 1, and the length direction of the first guide rod 81 is parallel to the optical axis. The focusing bracket 6 is slidably connected to the middle of the first guide rod 81. Exemplarily, the two ends of the first guide rod 81 are fixedly connected to the third fixing post 15 and the fourth fixing post 16, respectively. The length direction of the first guide rod 81 is parallel to the second direction. The first guide rod 81 is slidably connected within the second groove 621 of the second branch 62. Through the cooperation of the groove and the guide rod, the second branch 62 can realize the movement of the focusing bracket 6 relative to the base 1 in the second direction.

[0233] In some embodiments, the second groove 621 may have a "V" shaped structure. Exemplarily, the second groove 621 may include two third limiting surfaces 6211 arranged upwards along a third direction. The first guide rod 81 is located between the two third limiting surfaces 6211.

[0234] In some embodiments, the focusing ball 82 is rotatably connected between the focusing bracket 6 and the base 1. Exemplarily, the second plate portion 112 of the base plate 11 may be provided with a sixth groove 1121, within which the focusing ball 82 is movably mounted. The sixth groove 1121 may be used to limit the movement of the focusing ball 82. The focusing ball 82 is rotatably connected between the first support portion 61 of the focusing bracket 6 and the second plate portion 112 of the base 1.

[0235] In some embodiments, the motor 10 may further include a third sensor 573 and a third detection magnet 574. The third sensor 573 may be mounted on the base 1, and the third detection magnet 574 may be mounted on the focusing bracket 6. The third sensor 573 can be used to detect the displacement of the focusing bracket 6 relative to the base 1. Exemplarily, in a first direction or a third direction, the third sensor 573 and the third detection magnet 574 may be positioned opposite each other. The third sensor 573 can detect the displacement of the focusing bracket 6 relative to the base 1 based on the magnetic field of the third detection magnet 574.

[0236] Figure 18 yes Figure 5 The second image stabilization bracket 22 shown is a structural schematic diagram of one embodiment from another angle. Figure 19 yes Figure 18 The diagram shows the structure of the second image stabilization bracket 22 at another angle.

[0237] like Figure 18 and Figure 19 As shown, the second image stabilization bracket 22 may include a first part 221, a second part 222, a support part 223, a first connecting part 224, and a second connecting part 225. Figure 18 The first part 221 and the first connecting part 224, the second part 222 and the second connecting part 225 are schematically distinguished by dashed lines. Exemplarily, the first part 221 and the second part 222 can be arranged opposite each other and spaced apart, and the supporting part 223 can be fixedly connected between the first part 221 and the second part 222. The arrangement direction of the first part 221 and the second part 222 can be parallel to a third direction Y. The first connecting part 224 can protrude from the surface of the first part 221 facing away from the second part 222. The second connecting part 225 can protrude from the surface of the second part 222 facing away from the first part 221. The second connecting part 225 and the first connecting part 224 can be arranged spaced apart.

[0238] It is understood that, for ease of describing the basic structure and shape of the second image stabilization bracket 22, this embodiment describes the second image stabilization bracket 22 in five parts. However, this does not affect the fact that the second image stabilization bracket 22 can be a one-piece molded structural component. That is, the first part 221, the second part 222, the support part 223, the first connecting part 224, and the third connecting part 63 can all be one-piece molded structural components. In other embodiments, the second image stabilization bracket 22 can also be formed from different independent structural components through an assembly process. For example, the first part 221 and the second part 222 of the second image stabilization bracket 22 can be independent structural components and are fixedly connected to the support part 223 by means of adhesive bonding, welding, or other methods.

[0239] In some embodiments, the support portion 223 may have a bevel. The bevel can be used to match the shape of the optical path folding element 20 so that the support portion 223 can precisely support the optical path folding element 20.

[0240] For example, the first connecting portion 224 of the second image stabilization bracket 22 may be provided with a first receiving groove 2241. The opening of the first receiving groove 2241 is located on the bottom surface 2242 of the first connecting portion 224.

[0241] For example, the second connecting portion 225 of the second image stabilization bracket 22 may be provided with a second receiving groove 2251. The opening of the second receiving groove 2251 is located on the bottom surface 2252 of the second connecting portion 225.

[0242] Exemplarily, the first receiving groove 2241 and the second receiving groove 2251 may be arranged opposite each other in the third direction Y. In some embodiments, the arrangement direction of the first receiving groove 2241 and the second receiving groove 2251 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 2241 and the second receiving groove 2251 may have an angle of less than or equal to 5° with the third direction Y.

[0243] For example, the support portion 223 may be provided with a first groove 2231. The opening of the first groove 2231 may be located on the bottom surface 2232 of the support portion 223.

[0244] In other embodiments, the second image stabilization bracket 22 may not have the first part 221 and the second part 222.

[0245] Figure 20 yes Figure 5 The diagram shows an assembly schematic of one embodiment of the first image stabilization bracket 21 and the second image stabilization bracket 22 shown.

[0246] like Figure 20 As shown, the second image stabilization bracket 22 is movably connected to the first image stabilization bracket 21. The support portion 223 of the second image stabilization bracket 22 can be located inside the first image stabilization bracket 21. For example, along a third upward direction, the first portion 221 of the second image stabilization bracket 22 can be disposed opposite to the first arm 211 of the first image stabilization bracket 21, and the second portion 222 of the second image stabilization bracket 22 can be disposed opposite to the second arm 212 of the first image stabilization bracket 21. Along a first direction, the first connecting portion 224 of the second image stabilization bracket 22 can be disposed opposite to the first arm 211 of the first image stabilization bracket 21, and the second connecting portion 225 of the second image stabilization bracket 22 can be disposed opposite to the second arm 212 of the first image stabilization bracket 21.

[0247] Figure 21 yes Figure 20The diagram shows a partial cross-sectional view of one embodiment of the structure at GG. Figure 22 yes Figure 20 The structure shown is a partial cross-sectional view at HH from another angle.

[0248] like Figures 20 to 22 As shown, the second image stabilization bracket 22 can be movably connected to the first image stabilization bracket 21 via the first support member 521 and the second support member 522. Exemplarily, the first support member 521 can be rolled between the first connecting portion 224 of the second image stabilization bracket 22 and the first image stabilization bracket 21. The second support member 522 can be rolled between the second connecting portion 225 of the second image stabilization bracket 22 and the first image stabilization bracket 21. It is understood that, compared to a sliding connection between the first image stabilization bracket 21 and the second image stabilization bracket 22, the rolling connection of the first support member 521 and the second support member 522 helps to reduce the friction between the first image stabilization bracket 21 and the second image stabilization bracket 22.

[0249] In some embodiments, along the first direction, the first support member 521 can be connected between the first connecting portion 224 of the second image stabilization bracket 22 and the first arm 211 of the first image stabilization bracket 21, and the second support member 522 can be connected between the second connecting portion 225 of the second image stabilization bracket 22 and the second arm 212 of the first image stabilization bracket 21. For example, the first support member 521 can be fixedly connected within the first receiving groove 2241 of the first connecting portion 224 of the second image stabilization bracket 22, and roll-connected to the first limiting groove 2112 of the first arm 211 of the first image stabilization bracket 21. The second support member 522 can be fixedly connected within the second receiving groove 2251 of the second connecting portion 225 of the second image stabilization bracket 22, and roll-connected to the second limiting groove 2122 of the second arm 212 of the first image stabilization bracket 21. It is understood that the second image stabilization bracket 22 is connected to the first image stabilization bracket 21 on both sides of the bearing portion 223, which facilitates the smooth rotation of the second image stabilization bracket 22.

[0250] In some embodiments, the motor 10 further includes a second magnetic member 56. The second magnetic member 56 can be fixedly connected to the second anti-shake bracket 22. In one embodiment, there can be two second magnetic members 56, one of which can be fixedly connected to the first connecting portion 224 of the second anti-shake bracket 22, and the other of which can be fixedly connected to the second connecting portion 225 of the second anti-shake bracket 22. The second magnetic member 56 fixedly connected to the first connecting portion 224 of the second anti-shake bracket 22 can interact with the first magnetic member 32, and the second magnetic member 56 fixedly connected to the second connecting portion 225 of the second anti-shake bracket 22 can interact with the second magnetic member 34 to provide a magnetic attraction force parallel to the first direction, for pressing the second anti-shake bracket 22 onto the first anti-shake bracket 21, so as to maintain a close fit between the second anti-shake bracket 22 and the first anti-shake bracket 21 during movement.

[0251] It is understood that the second magnetic attractor 56 in this embodiment uses a magnetically conductive material, and the second magnetic attractor 56 cooperates with the first magnetic element 32 and the second magnetic element 34 to provide magnetic attraction. In other embodiments, the second magnetic attractor 56 may also use a magnetic material, and the motor 10 may additionally provide a magnetically conductive element, which cooperates with the second magnetic attractor 56 to provide magnetic attraction parallel to the first direction.

[0252] In other embodiments, the second image stabilization bracket 22 and the first image stabilization bracket 21 can be supported in a second direction. This application is not limiting.

[0253] Figure 23 yes Figure 4 The diagram shows a partial structural schematic of the motor 10 shown. Figure 24 yes Figure 23 The structure shown is a partial cross-sectional view at point II from another angle.

[0254] like Figure 23 and Figure 24 As shown, the third magnetic element 36 can be fixedly connected to the second image stabilization bracket 22. The third coil 35 is fixedly connected to the first plate portion 111 of the base 1. Along the first direction, the third magnetic element 36 on the second image stabilization bracket 22 and the third coil 35 on the base 1 face each other. The third coil 35 and the third magnetic element 36 can cooperate with each other to provide a driving force to the second image stabilization bracket 22 in the second direction, so as to drive the second image stabilization bracket 22 to rotate relative to the first image stabilization bracket 21 about the second axis R2. The second axis R2 is perpendicular to the second direction. The first support member 521 and the second support member 522 can be arranged opposite each other in a direction parallel to the second axis R2. For example, when the first support member 521 and the second support member 522 are ball bearings, the line connecting the center of the first support member 521 and the center of the second support member 522 is parallel to the second axis R2.

[0255] It is understood that the second image stabilization bracket 22 and the first image stabilization bracket 21 are connected by the cooperation of the first support member 521, the second support member 522, the first limiting groove 2112, and the second limiting groove 2122, which restricts the translation of the second image stabilization bracket 22 in the XY plane. The second magnetic suction member is used to press the second image stabilization bracket 22 firmly onto the first image stabilization bracket 21. When the second image stabilization bracket 22 is subjected to a driving force along the second direction, it can rotate around the second axis R2.

[0256] It is understandable that when the motor 10 is performing image stabilization, the first image stabilization bracket 21 and the second image stabilization bracket 22 can move simultaneously, thereby achieving image stabilization in multiple directions. When both the first image stabilization bracket 21 and the second image stabilization bracket 22 are moving, the second image stabilization bracket 22 rotates around the second axis R2. The second axis R2 may not be perpendicular to the first direction; it may be perpendicular only to the second direction. When the first image stabilization bracket 21 is stationary relative to the base 1, the second image stabilization bracket 22 rotates around the second axis R2. At this time, the second axis R2 may be perpendicular to both the first and second directions.

[0257] For example, the third magnetic element 36 can be assembled from multiple magnets. Figure 24 The third magnetic component 36 is illustrated by the same filling pattern, which represents multiple magnets.

[0258] In other embodiments, the third magnetic element 36 and the third coil 35 may also be arranged opposite each other along the second direction or the third direction.

[0259] In other embodiments, the positions of the third magnetic element 36 and the third coil 35 can be interchanged.

[0260] In some embodiments, the motor 10 may further include a second sensor 571. The second sensor 571 may be fixedly connected to the second anti-shake bracket 22. The second sensor 571 may be used to detect the displacement of the second anti-shake bracket 22 relative to the base 1. Exemplarily, the second sensor 571 is disposed on one side of the third coil 35. The second sensor 571 may detect the displacement of the second anti-shake bracket 22 relative to the base 1 based on the magnetic field of the third magnetic element 36. It is understood that, compared to the scheme of disposing the second sensor 571 on the inner side of the third coil 35, in this embodiment, disposing the second sensor 571 on the outer side of the third coil 35 is beneficial to reducing the excitation interference of the third coil 35 on the second sensor 571 after it is energized, and is beneficial to improving the position detection accuracy of the second sensor 571, thereby improving the control accuracy.

[0261] In some embodiments, the motor 10 may further include a second detection magnet 572. The second detection magnet 572 may be fixedly connected to the base 1. The second sensor 571 may be used to detect the magnetic field of the second detection magnet 572 and / or the third magnetic element 36, thereby realizing the displacement detection of the second anti-shake bracket 22 in the XZ plane. Exemplarily, along the first direction, the second sensor 571 and the second detection magnet 572 are arranged opposite to each other. The second sensor 571 simultaneously detects the magnetic fields of the second detection magnet 572 and the third magnetic element 36. The second detection magnet 572 may form a closed loop with the third magnetic element 36 to extend the magnetic field, so that the magnetic field strength that the second sensor 571 can detect is greater, which is beneficial to improving the detection accuracy of the second sensor 571, thereby improving the control accuracy of the motor 10.

[0262] In other embodiments, the second sensor 571 may also be disposed inside the third coil 35.

[0263] In other embodiments, when the third magnetic element 36 is fixed to the base 1, the second sensor 571 can be fixed to the second anti-shake bracket 22.

[0264] Figure 25 yes Figure 5 The diagram shows a structural schematic of one embodiment of the outer casing 9. Figure 26 yes Figure 25 The diagram shows the structure of the outer shell 9 from another angle.

[0265] like Figure 25 and Figure 26 As shown, the shape of the outer shell 9 can be adapted to the shape of the base 1. The outer shell 9 can be roughly square-shaped.

[0266] Exemplarily, the housing 9 may include a top wall 91 and a side wall 92. The side wall 92 may be connected to the periphery of the top wall 91. The top wall 91 may have a first through hole 911, and the side wall 92 may have a second through hole 925. Exemplarily, the side wall may include a first side wall 921, a second side wall 922, a third side wall 923, and a fourth side wall 924. The first side wall 921, the second side wall 922, the third side wall 923, and the fourth side wall 924 may be located on the same side of the top wall 91 and fixedly connected to the top wall 91. Exemplarily, the light inlet 1001 of the motor 10 may be located on the top wall 91. The light outlet 1002 of the motor 10 may be located on the fourth side wall 924. The light inlet 1001 and the light outlet 1002 may communicate with each other.

[0267] It is understood that, in order to facilitate the description of the specific structure and shape of the outer shell 9, the outer shell 9 is described in multiple parts in this embodiment, but this does not affect the fact that the outer shell 9 can be a one-piece molded structural component, that is, the top wall 91, the first side wall 921, the second side wall 922, the third side wall 923 and the fourth side wall 924 can be one-piece molded structural components.

[0268] Figure 27 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the structure at JJ.

[0269] like Figures 25 to 27 As shown, the housing 9 can be fixedly connected to the base 1, and the housing 9 and the base 1 enclose a receiving space 110. The optical path folding element 20 and the focusing lens group 30 are located within the receiving space 110. For example, the housing 9 can be fixedly connected to the base 1 by means of adhesive, welding, etc. The housing 9 can be assembled and cooperated with the base 1 to jointly encapsulate and protect the internal structure of the motor 10, such as the image stabilization bracket 2, the focusing bracket 6, the focusing lens group 30, etc.

[0270] In some embodiments, the sidewall 92 of the housing 9 can be fixedly connected to the base 1. The top wall 91 has a first through hole 911. The sidewall 92 has a second through hole 925. The first through hole 911 connects to the light inlet hole 1001 of the base 1. The second through hole 925 connects to the light outlet hole 1002 of the base 1. Light propagates into the motor 10 along a first direction through the first through hole 911 and the light inlet hole 1001. After exiting the focusing lens group 30, the light propagates out of the motor 10 along a second direction through the light outlet hole 1002 and the second through hole 925. Exemplarily, the first sidewall 921, the second sidewall 922, the third sidewall 923, and the fourth sidewall 924 of the housing 9 can be fixedly connected to the base 1. The fourth sidewall 924 of the housing 9 and the back plate 12 of the base 1 can be arranged opposite each other in the second direction. It is understood that the housing 9 is installed after the assembly of the optical path folding element 20, the focusing lens group 30, and the motor 10 is completed. The housing 9 and the base 1 are connected during the assembly process of the camera module 100 to prevent the housing 9 from interfering with the installation of the focusing lens group 70. A first through hole 911 and a second through hole 925 are provided on the housing 9 to allow light to pass through.

[0271] In some embodiments, the top wall 91 of the outer casing 9 may include a first portion 912 and a second portion 913. The first portion 912 and the second portion 913 may be arranged along a second direction. A first through hole 911 may be located on the first portion 912. Along the first direction, the first portion 912 may be disposed opposite to the first support portion 104 of the base 1, and the second portion 913 may be disposed opposite to the second support portion 105 of the base 1. The first portion 912 and the second portion 913 may be integrally formed structural components. It is understood that the integrally formed structural components of the first portion 912 and the second portion 913 are beneficial to reducing the number of components included in the camera module 100, reducing the number of assembly steps of the camera module 100, and reducing the manufacturing cost of the camera module 100. Furthermore, since the first portion 912 and the second portion 913 are integrally formed structural components, no additional process is required for alignment between the first portion 912 and the second portion 913, nor is any additional connecting structure or fixing process required to connect the two, which is beneficial to improving the structural strength of the outer casing 9 and improving the reliability of the outer casing 9.

[0272] In other embodiments, the housing 9 may also exclude the sidewalls 92 and only have a top wall 91.

[0273] The second embodiment, which shares the same technical content as the first embodiment, will not be repeated here: In the previous embodiment, the first support member 521 and the second support member 522 are arranged along a first direction between the first image stabilization bracket 21 and the second image stabilization bracket 22. In this embodiment, the first support member 521 and the second support member 522 may also be arranged along a second direction between the first image stabilization bracket 21 and the second image stabilization bracket 22. This will be described in detail below with reference to the accompanying drawings.

[0274] Figure 28 yes Figure 4 The diagram shows a partially exploded view of another embodiment of the motor 10 shown. Figure 29 yes Figure 28 The diagram shows an exploded view of the motor 10 in some embodiments.

[0275] like Figure 28 and Figure 29 As shown, the motor 10 may include a base 1, an image stabilization bracket 2, an image stabilization drive mechanism 3, a positioning ball bearing 4, a support member 51, a focusing bracket 6, a focusing drive mechanism 7, a first guide rod 81, a second guide rod 83, a stop member 58, a magnetic absorbing plate 591, and a magnetic magnet 592. The arrangement of the base 1, the image stabilization drive mechanism 3, the positioning ball bearing 4, the support member 51, the focusing bracket 6, the focusing drive mechanism 7, and the first guide rod 81 can refer to the arrangement in the previously described embodiment, and will not be repeated below.

[0276] Figure 30 yes Figure 29 The first image stabilization bracket 21 shown is a structural schematic diagram of one embodiment from another angle. Figure 31 yes Figure 30 The diagram shows the structure of the first image stabilization bracket 21 at another angle.

[0277] like Figure 30 and Figure 31 As shown, the connecting arm 213 of the first image stabilization bracket 21 may be provided with a seventh groove 2138. The opening of the seventh groove 2138 may be located on the first surface 2131 of the connecting arm 213. The seventh groove 2138 may be used to install a magnetic clasp 591.

[0278] In some embodiments, the first arm 211 of the first image stabilization bracket 21 may be provided with a sixth mounting groove 2117. The sixth mounting groove 2117 may be used to mount a first support member 521. The second arm 212 of the first image stabilization bracket 21 may be provided with a fifth mounting groove 2123. The fifth mounting groove 2123 may be used to mount a second support member 512. Exemplarily, the first arm 211 may be fixedly connected to the first surface 2131 of the connecting arm 213. The opening of the sixth mounting groove 2117 may be located on the side surface of the first arm 211 away from the connecting arm 213. The second arm 212 may be fixedly connected to the first surface 2131 of the connecting arm 213. The opening of the fifth mounting groove 2123 may be located on the side surface of the second arm 212 away from the connecting arm 213.

[0279] For example, the first arm 211 may include a first sub-part 2114 and a second sub-part 2115. Figure 30 The first sub-part 2114 and the second sub-part 2115 are schematically distinguished by dotted lines. The first sub-part 2114 and the second sub-part 2115 are arranged along a second direction. The first sub-part 2114 is fixedly connected to the first surface 2131 of the connecting arm 213. The second sub-part 2115 is fixedly connected to the end of the first sub-part 2114 away from the connecting arm 213. The second sub-part 2115 and the first sub-part 2114 roughly form an "L" shape. The seventh groove 2138 may be located on the first sub-part 2114. It is understood that the shape and structure of the second support arm 212 can refer to the arrangement of the first support arm 211, and will not be described in detail here.

[0280] In some embodiments, the first stabilization bracket 21 may be provided with a first clearance groove 214. The first clearance groove 214 may be used to avoid the stop member 58.

[0281] Figure 32 yes Figure 29 The second image stabilization bracket 22 shown is a structural schematic diagram of one embodiment from another angle.

[0282] like Figure 32As shown, the second image stabilization bracket 22 may include a first part 221, a second part 222, a support part 223, a first connecting part 224, and a second connecting part 225. Figure 32 The first part 221 and the first connecting part 224, the second part 222 and the second connecting part 225 are schematically distinguished by dashed lines. In this embodiment, the second image stabilization bracket 22 is provided with a third limiting groove 226 and a fourth limiting groove 227. The opening of the third limiting groove 226 can be located in the first connecting part 224 of the second image stabilization bracket 22, and the opening of the fourth limiting groove 227 can be located in the second connecting part 225 of the second image stabilization bracket 22. The third limiting groove 226 and the fourth limiting groove 227 can be used to accommodate the first support member 521 and the second support member 522.

[0283] In some embodiments, the second image stabilization bracket 22 may be provided with an eighth groove 228. The eighth groove 228 may be used to accommodate a magnetic magnet 592.

[0284] In some embodiments, the second stabilizing bracket 22 may be provided with a second clearance groove 229. The second clearance groove 229 may be used to avoid the stop member 58.

[0285] Figure 33 yes Figure 28 The motor 10 shown is a partial cross-sectional view of one embodiment at KK from another angle.

[0286] like Figure 33 As shown, the second image stabilization bracket 22 can be movably connected to the first image stabilization bracket 21 via the first support member 521 and the second support member 522. Exemplarily, along the second direction, the first support member 521 can be rotatably connected between the first connecting portion 224 of the second image stabilization bracket 22 and the first arm 211 of the first image stabilization bracket 21, and the second support member 522 can be rotatably connected between the second connecting portion 225 of the second image stabilization bracket 22 and the second arm 212 of the first image stabilization bracket 21.

[0287] Exemplarily, the motor 10 may further include a first metal insert 97. The first metal insert 97 may be embedded in the first anti-shake bracket 21. The first metal insert 97 is exposed at the bottom of the sixth mounting groove 2117 and the fifth mounting groove 2123. In this way, the first support member 521 and the second support member 522 can be rolled to the first metal insert 97. The hardness of the first metal insert 97 on the first anti-shake bracket 21 is greater than the hardness of the first anti-shake bracket 21, and the first metal insert 97 has better wear resistance, which is beneficial to extending the service life of the motor 10.

[0288] Exemplarily, the motor 10 may further include a second metal insert 96. The second metal insert 96 may be embedded in the second anti-shake bracket 22. The second metal insert 96 may be used to form a third limiting groove 226 and a fourth limiting groove 227. In this way, the first support member 521 and the second support member 522 can be rolledly connected to the second metal insert 96. The hardness of the second metal insert 96 is greater than that of the first anti-shake bracket 21, and the second metal insert 96 has better wear resistance, which is beneficial to extending the service life of the motor 10.

[0289] Figure 34 yes Figure 28 The motor 10 shown is a partial cross-sectional view of one embodiment at another angle at LL.

[0290] like Figure 33 and Figure 34 As shown, one of the magnetic magnet 592 and the magnetic plate 591 is fixed to the first image stabilization bracket 21, and the other is fixed to the second image stabilization bracket 22. The magnetic magnet 592 and the magnetic plate 591 are arranged opposite each other along the second direction. Thus, the magnetic attraction between the magnetic magnet 592 and the magnetic plate 591 allows the first image stabilization bracket 21 and the second image stabilization bracket 22 to be stably supported in the second direction. For example, the magnetic plate 591 can be installed in the seventh groove 2138 of the first image stabilization bracket 21, and the magnetic magnet 592 can be installed in the eighth groove 228 of the second image stabilization bracket 22.

[0291] In some embodiments, the center of the magnetic magnet 592 and the second axis are both located in a first plane, with the first axis R1 parallel to the first plane. It is understood that the center of the magnetic magnet 592 and the second axis are coplanar, and the first axis R1 is parallel to the first plane. The magnetic force acting on the magnetic magnet 592 can pass through the second axis R2, which helps to reduce the interfering torque that hinders the rotation of the second image stabilization bracket 22 around the second axis R2.

[0292] In some embodiments, the center of the magnetic clasp 591 is located within the first plane. That is, the center of the magnetic clasp 591 can also be coplanar with the second axis R2. This can further reduce the interfering torque that prevents the second image stabilization bracket 22 from rotating around the second axis R2.

[0293] It is understood that the magnetic magnet 592 can be a single magnet or it can consist of multiple magnets. This application uses the example of the magnetic magnet 592 being a single magnet for illustration.

[0294] In some embodiments, the magnetic magnet 592 can be a single-sided bipolar magnet. A single-sided bipolar magnet refers to a magnet that simultaneously possesses both north and south poles on one side. It is understood that, compared to a single-sided unipolar magnet, the use of a single-sided bipolar magnet in this embodiment is beneficial for concentrating the magnetic field near the magnetic magnet 592, reducing electromagnetic interference between the magnetic magnet 592 and other nearby devices. Furthermore, compared to assembling two magnets, the single-sided bipolar configuration of a single magnet can reduce assembly process costs.

[0295] In some embodiments, when the magnetic attractor 592 is a single-sided bipolar magnet, the magnetic attractor 592 includes a first portion 5921, a second portion 5922, and a transition portion 5923, which are schematically distinguished by dashed lines in the figure. The polarity direction of the first portion 5921 is opposite to that of the second portion 5922. The transition portion 5923 has no magnetic field.

[0296] In some embodiments, the motor 10 may further include a first magnetic member 55. The first magnetic member 55 may be fixedly connected to the first anti-shake bracket 21. The first magnetic member 55 may be disposed opposite to the metal insert 121 in a direction parallel to the second direction. The first magnetic member 55 may interact with the metal insert 121 to provide a magnetic attraction force parallel to the second direction, so that the first anti-shake bracket 21 and the base 1 can be stably supported in the second direction. Exemplarily, the first magnetic member 55 may be a single-sided bipolar magnet.

[0297] Figure 35 yes Figure 33 An enlarged schematic diagram of one embodiment of the magnetic magnet 592 shown.

[0298] like Figures 33 to 35 As shown, when the magnetic magnet 592 is a single-sided bipolar magnet, it is fixed to the second image stabilization bracket 22. The surface of the magnetic magnet 592 facing the magnetic plate 591 is the first surface S1, which has two polarities. That is, the first surface S1 simultaneously possesses both north and south pole magnetism. This results in a stronger magnetic attraction between the magnetic magnet 592 and the magnetic plate 591, leading to better stability between the second image stabilization bracket 22 and the first image stabilization bracket 21.

[0299] In some embodiments, the surface of the first magnetic member 55 facing the metal insert 121 may also have two polarities. In this way, the magnetic attraction between the first magnetic member 55 and the metal insert 121 can be greater.

[0300] Figure 36 yes Figure 33 An enlarged schematic diagram of another embodiment of the structure shown from another angle.

[0301] like Figure 36 As shown, the surface of the magnetic magnet 592 facing the magnetic plate 591 is the first surface S1, which is an arc surface that bulges towards the magnetic plate 591. It can be understood that, compared to a flat surface, when the first surface S1 is an arc surface, the minimum distance between the magnetic magnet 592 and the magnetic plate 591 changes less in the second direction during the rotation of the second image stabilization bracket 22, and the magnetic attraction force between them changes less, which is beneficial to the stability between the second image stabilization bracket 22 and the first image stabilization bracket 21.

[0302] In some embodiments, the first surface S1 is a sphere, and the center of the sphere is located on the second axis R2. Along the first direction, the projection of the center of the sphere on the first surface S1 can coincide with the first axis R1. It is understood that during the rotation of the second image stabilization bracket 22 around the second axis, the minimum distance between the magnetic magnet 592 and the magnetic plate 591 in the second direction remains unchanged, and the magnitude of the magnetic attraction between the magnetic magnet 592 and the magnetic plate 591 remains unchanged, which is beneficial to the stability between the second image stabilization bracket 22 and the first image stabilization bracket 21.

[0303] Figure 37 yes Figure 29 A schematic diagram of an embodiment of the stop 58 and base 1 shown. Figure 38 yes Figure 28 The motor 10 shown is a partial cross-sectional view of one embodiment at another angle at MM. Figure 39 yes Figure 28 The motor 10 shown is a partial cross-sectional view of one embodiment at another angle at NN.

[0304] like Figures 37 to 39 As shown. The stop member 58 is fixedly connected to the base 1. Exemplarily, the stop member 58 is fixedly connected to the first plate portion 111 of the base plate 11. Along the second direction, the stop member 58 is located on the side of the first anti-shake bracket 21 away from the positioning ball 4, and the stop member 58 is spaced apart from the first anti-shake bracket 21 and the second anti-shake bracket 22. It can be understood that by setting the stop member 58, the movement space of the first anti-shake bracket 21 in the second direction can be controlled, preventing excessive displacement of the first anti-shake bracket 21 in the second direction, which could cause the positioning ball to fall off, and preventing the movement of the first anti-shake bracket 21 from jamming. The stop member 58 is spaced apart from the first anti-shake bracket 21 and the second anti-shake bracket 22 to prevent the stop member 58 from interfering with the rotation of the first anti-shake bracket 21 and the second anti-shake bracket 22.

[0305] In some embodiments, the number of stop members 58 can be one or more. The figure illustrates two stop members 58: a first stop member 581 and a second stop member 582. The first stop member 581 is fixedly connected to the base 1, with a portion located within the third clearance groove 215 of the first anti-shake bracket 21. The second stop member 582 is fixedly connected to the base 1, with a portion located within the first clearance groove 214 of the first anti-shake bracket 21 and a portion located within the second clearance groove 229 of the second anti-shake bracket 22. It is understood that by providing clearance grooves on the first anti-shake bracket 21 and / or the second anti-shake bracket 22, the stop member 58 can be accommodated without increasing the volume of the motor 10. In other embodiments, one of the first clearance groove 214 and the second clearance groove 229 may be selectively provided.

[0306] In some embodiments, the distance D3 between the stop 58 and the first image stabilization bracket 21 along the second direction is in the range of 0.005mm to 0.5mm. This ensures that the distance between the stop 58 and the first image stabilization bracket 21 along the second direction is within a suitable range. On the one hand, this prevents excessive displacement of the first image stabilization bracket 21 in the second direction, which could cause the positioning ball to fall off. On the other hand, it effectively prevents the stop 58 from interfering with the rotation of the first image stabilization bracket 21.

[0307] Figure 40 yes Figure 29 The diagram shows an assembly schematic of one embodiment of the first guide rod 81, the second guide rod 83, and the base 1. Figure 41 yes Figure 28 The motor 10 shown is a partial cross-sectional view of one embodiment of OO at another angle.

[0308] like Figure 40 and Figure 41 As shown, the two ends of the first guide rod 81 are fixedly connected to the base 1, and the length direction of the first guide rod 81 is parallel to the optical axis. The two ends of the second guide rod 83 are fixedly connected to the base 1, and the length direction of the second guide rod 83 is parallel to the optical axis. The focusing bracket is slidably connected to the middle of the first guide rod 81 and the second guide rod 83. Exemplarily, the two ends of the second guide rod 83 can be fixedly connected to the first fixing post 13 and the second fixing post 14, respectively. The length direction of the first guide rod 81 is parallel to the second direction. The two ends of the first guide rod 81 can be fixedly connected to the third fixing post 15 and the fourth fixing post 16, respectively. The length direction of the second guide rod 83 is parallel to the second direction.

[0309] It is understood that in this embodiment, the focusing bracket is slidably connected to the base 1 via the first guide rod 81 and the second guide rod 83. This application does not limit the specific implementation of the focusing bracket's movable connection to the base 1; those skilled in the art can make modifications according to their needs.

[0310] The third implementation method, which shares the same technical content as the first implementation method, will not be described again: Figure 42 This is a partial structural schematic diagram of another embodiment of the motor 10 provided in this application. Figure 43 yes Figure 42 The diagram shows a partial cross-sectional view of one embodiment of the motor 10 at PP.

[0311] like Figure 42 and Figure 43 As shown, along the second direction, the first support member 521 is rotatably connected between the bearing portion 223 of the second image stabilization bracket 22 and the connecting arm 213 of the first image stabilization bracket 21, and the second support member 522 is rotatably connected between the bearing portion 223 of the second image stabilization bracket 22 and the connecting arm 213 of the first image stabilization bracket 21. When the optical path folding element 20 is installed on the motor 10, the first support member 521 and the second support member 522 can be arranged opposite to the optical path folding element 20 in the second direction. Exemplarily, along the third direction, the magnetic magnet 592 can be located between the first support member 521 and the second support member 522.

[0312] It is understood that this application does not limit the position of the first support member 521 and the second support member 522 between the first image stabilization bracket 21 and the second image stabilization bracket 22, and those skilled in the art can set them according to their needs.

[0313] The fourth implementation method, which shares the same technical content as the first implementation method, will not be described again: Figure 44 This is a partial structural schematic diagram of another embodiment of the motor 10 provided in this application. Figure 45 yes Figure 44 A partial cross-sectional view of one embodiment of the motor 10 at RR shown. Figure 46 yes Figure 44 The motor 10 shown is a partial cross-sectional view of one embodiment at SS from another angle.

[0314] like Figures 44 to 46As shown, in this embodiment, the anti-shake drive mechanism 3 of the anti-shake bracket 2 is mounted on the second anti-shake bracket 22 and the base 1. The first anti-shake bracket 21 is driven to rotate around the first axis R1 by the second anti-shake bracket 22. Exemplarily, the first connecting portion 224 of the second anti-shake bracket 22 may be provided with a ninth groove 2243. The opening of the ninth groove 2243 may face the first side plate 17 of the base 1. The second connecting portion 225 of the second anti-shake bracket 22 may be provided with a tenth groove 2253. The opening of the tenth groove 2253 may face the second side plate 18 of the base 1. The first magnetic element 32 may be fixedly connected to the ninth groove 2243 of the first connecting portion 224 of the second anti-shake bracket 22. The second magnetic element 34 may be fixedly connected to the tenth groove 2253 of the second connecting portion 225 of the second anti-shake bracket 22.

[0315] It is understood that in this embodiment, the first image stabilization bracket 21 may not have a first arm 211 and a second arm 212. The first magnetic element 32 and the second magnetic element 34 are disposed on the second image stabilization bracket 22.

[0316] In other embodiments, the positions of the first coil 31 and the first magnetic element 32 can be interchanged. The positions of the second coil 33 and the second magnetic element 34 can also be interchanged.

[0317] In some embodiments, the second image stabilization bracket 22 drives the first image stabilization bracket 21 to move relative to the base 1 through the cooperation of the first limiting groove 2112, the second limiting groove 2122, the first support member 521, and the second support member 522. The first image stabilization bracket 21 can rotate relative to the base 1 around the first axis R1 through the cooperation of the positioning ball 4 and the positioning groove 103 of the base 1.

[0318] For example, when the second image stabilization bracket 22 is driven by the image stabilization drive mechanism 3, the first support member 521 can be fixedly connected to the second image stabilization bracket 22 and abut against the first limiting groove 2112 to apply a driving force to the first image stabilization bracket 21.

[0319] It is understood that in the previous embodiment, the first magnetic element 32 and the second magnetic element 34 are both disposed on the first image stabilization bracket 21, directly driving the first image stabilization bracket 21 to move relative to the base 1. In this embodiment, the first magnetic element 32 and the second magnetic element are both disposed on the second image stabilization bracket 22, driving the second image stabilization bracket 22 to move relative to the base 1. The first image stabilization bracket 21 and the second image stabilization bracket 22 are connected by a limiting structure, allowing the second image stabilization bracket 22 to drive the first image stabilization bracket 21 to move relative to the base 1. This application is not limited to the image stabilization drive mechanism 3 directly driving the first image stabilization bracket 21 to move; the motor can also indirectly drive the first image stabilization bracket 21 to rotate around the first axis R1 through the second image stabilization bracket 22.

[0320] 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.

[0321] 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.

[0322] 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.
