[0001] This invention belongs to the field of camera technology, and in particular relates to a stabilization mechanism and electronic device. Background Technology

[0002] In electronic devices such as mobile phones and tablets, image stabilization mechanisms are typically incorporated to stabilize the camera lens and improve image quality. However, current technologies often use one or two lenses per stabilization mechanism, resulting in a large space requirement for the stabilization unit and hindering the reduction of the device's overall size.

[0003] Therefore, it is necessary to provide a new image stabilization mechanism that can be used for multi-lens image stabilization simultaneously. Summary of the Invention

[0007] Furthermore, in some embodiments, the movable bracket further includes a first side plate and a second side plate that bend from the outer periphery of the base plate and extend in the first direction away from the base plate, the first side plate and the second side plate being perpendicular to each other; the frame further includes a first frame and a second frame that bend from the outer periphery of the base frame and extend in the first direction away from the base frame, the first frame and the second frame being perpendicular to each other, the first side plate and the first frame being spaced apart relative to each other in a direction parallel to the second rotation axis, and the second side plate and the second frame being spaced apart relative to each other in a direction parallel to the first rotation axis; the first driving assembly includes a first magnetic structure fixedly mounted on the first side plate and a first coil fixedly mounted on the first frame; the second driving assembly includes a second magnetic structure fixedly mounted on the second side plate and a second coil fixedly mounted on the second frame.

[0008] Furthermore, in some embodiments, the magnetization directions of the first magnetic structure and the second magnetic structure are parallel to the first direction, the first coil and the second coil are ring coils, and the central axis of the first coil is perpendicular to the first frame, and the central axis of the second coil is perpendicular to the second frame.

[0009] Furthermore, in some embodiments, the first frame has a first groove extending in a direction parallel to the second rotating axis, the second frame has a second groove extending in a direction parallel to the first rotating axis, the first coil is fixedly assembled in the first groove, and the second coil is fixedly assembled in the second groove.

[0010] Furthermore, in some embodiments, the first side plate has a first mounting groove extending in a direction parallel to the second rotating axis, and the second side plate has a second mounting groove extending in a direction parallel to the first rotating axis. The first magnetic structure is fixedly mounted in the first mounting groove, and the second magnetic structure is fixedly mounted in the second mounting groove. The first magnetic structure and the first coil are arranged relatively spaced apart in a direction parallel to the second rotating axis, and the second magnetic structure and the second coil are arranged relatively spaced apart in a direction parallel to the first rotating axis.

[0011] Furthermore, in some embodiments, the first driving assembly further includes a first circuit board located on the side of the first coil facing away from the first magnetic structure in a direction parallel to the second rotating axis, the first circuit board being attached to the side of the first frame facing away from the first side plate in a direction parallel to the second rotating axis; the second driving assembly further includes a second circuit board located on the side of the second coil facing away from the second magnetic structure in a direction parallel to the first rotating axis, the second circuit board being attached to the side of the second frame facing away from the second side plate in a direction parallel to the first rotating axis; the first coil and the first circuit board are electrically connected, and the second coil and the second circuit board are electrically connected.

Both the first and second drive components can drive the movable bracket to rotate relative to the frame around the support structure. Specifically, when the first drive component is active and the second drive component is inactive, the first drive component can drive the movable bracket to rotate relative to the frame along a first axis of rotation; when the second drive component is active and the first drive component is inactive, the second drive component can drive the movable bracket to rotate relative to the frame along a second axis of rotation; when both the first and second drive components work together, under their influence, the movable bracket can rotate along any other axis of rotation, and this other axis of rotation is parallel to the base surface (the base surface is a plane containing the first and second axes of rotation) and passes through the support structure. This allows for multi-directional and multi-angle rotation of the movable bracket. Furthermore, since multiple lens modules are mounted on the movable bracket, these modules can be driven to rotate in multiple directions and angles, thereby achieving multi-directional and multi-angle image stabilization and improving shooting quality. Furthermore, a single image stabilization mechanism can integrate multiple lens modules. Thus, compared to related technologies where one or two lens modules are configured with a single image stabilization mechanism, the image stabilization mechanism of this invention can be used for multi-lens image stabilization simultaneously. This reduces the number of image stabilization mechanisms within the entire device, reduces the space occupied by the image stabilization mechanisms, and helps to reduce the size of electronic devices. Moreover, it can improve image stabilization stability and the consistency of multi-lens image stabilization performance, better enhance shooting effects, and expand applications such as multi-lens image fusion.

[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "circumferential," and "radial," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, 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, and therefore should not be construed as a limitation of this invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] Please see Figures 1 to 4 The first aspect of this invention provides a stabilization mechanism 10, including a frame 1, a support structure 3 sequentially disposed on the frame 1 along a first direction, and a movable bracket 2 movably supported on the frame 1 by the support structure 3; the stabilization mechanism 10 further includes a first driving component 4 for driving the movable bracket 2 to rotate around a first rotating axis and a second driving component 5 for driving the movable bracket 2 to rotate around a second rotating axis, the first rotating axis and the second rotating axis both passing through the support structure 3, and the first rotating axis, the second rotating axis and the first direction are perpendicular to each other; the movable bracket 2 is driven by the first driving component 4 and / or the second driving component 5 to rotate around the support structure 3 as a fulcrum; a plurality of lens modules 20 are mounted on the movable bracket 2.

[0022] In this embodiment of the invention, the support structure 3 not only provides support for the movable bracket 2, but also serves as a fulcrum for the movable bracket 2 to rotate relative to the frame 1, thereby satisfying the motion freedom requirements of the movable bracket 2. Both the first drive assembly 4 and the second drive assembly 5 can drive the movable bracket 2 to rotate relative to the frame 1 around the support structure 3. Specifically, when the first drive assembly 4 is active and the second drive assembly 5 is inactive, the first drive assembly 4 can drive the movable bracket 2 to rotate relative to the frame 1 along the first axis of rotation; when the second drive assembly 5 is active and the first drive assembly 4 is inactive, the second drive assembly 5 can drive the movable bracket 2 to rotate relative to the frame 1 along the second axis of rotation; when the first drive assembly 4 and the second drive assembly 5 work together, under the influence of the first drive assembly 4 and the second drive assembly 5, the movable bracket 2 can rotate along any other axis of rotation, and this other axis of rotation is parallel to the base surface (the base surface is a plane containing the first and second axes of rotation) and passes through the support structure 3. Thus, multi-directional and multi-angle rotation of the movable bracket 2 can be achieved. Furthermore, since the movable bracket 2 is equipped with multiple lens modules 20, these modules can be rotated in multiple directions and angles, thereby achieving multi-directional and multi-angle image stabilization and improving shooting quality. Additionally, one image stabilization mechanism 10 can integrate multiple lens modules 20. Therefore, compared to related technologies where one or two lens modules 20 are used for one image stabilization mechanism 10, the image stabilization mechanism 10 of this embodiment can be used for multi-lens image stabilization simultaneously. This reduces the number of image stabilization mechanisms 10 within the entire device, reduces the space occupied by these mechanisms, and helps to reduce the size of the electronic device. Moreover, it can improve image stabilization stability and the consistency of multi-lens image stabilization performance, better enhance shooting effects, and expand applications such as multi-lens image fusion.

[0023] Understandably, the first axis of rotation, the second axis of rotation, the axis of rotation, and the base surface are not physical entities, but rather represent abstract concepts.

[0024] For ease of understanding, the first rotating shaft L1 is... Figure 1 The above is shown with a dashed line, and the first axis of rotation is parallel to... Figure 1 and Figure 3 The X-axis direction; the second rotating shaft L2 in Figure 1 The upper part is shown with a dashed line, and the second axis of rotation is parallel to... Figure 1 and Figure 3 The Y-axis direction in the middle, the first direction is Figure 1 and Figure 3 The Z-axis direction in the equation.

[0025] Furthermore, when the first drive assembly 4 and the second drive assembly 5 work together, the movable bracket 2 will rotate along which other rotation axis, depending on the magnitude and direction of the force exerted by the first drive assembly 4 and the second drive assembly 5.

[0026] Furthermore, in some embodiments, the frame 1 includes a bottom frame 11 arranged perpendicular to the first direction, the movable bracket 2 includes a base plate 21 arranged at a distance from the bottom frame 11 in the first direction, the support structure 3 includes a universal ball structure 31 assembled on the side of the bottom frame 11 facing the base plate 21 in the first direction, and a plurality of lens modules 20 formed on the side of the base plate 21 facing away from the universal ball structure 31 in the first direction; the side of the base plate 21 facing the universal ball structure 31 in the first direction is recessed to form a groove 212 in the direction away from the universal ball structure 31, and the universal ball structure 31 is movably sleeved in the groove 212.

[0027] Specifically, the base frame 11 and the base plate 21 are spaced apart along the first direction. In this way, when the movable bracket 2 rotates relative to the frame 1, the base frame 11 and the base plate 21 can avoid mutual interference, thus achieving anti-shake compensation. In addition, the support structure 3 can be a universal ball structure 31. The groove 212 on the base plate 21 can match the shape of the universal ball structure 31. Therefore, when the movable bracket 2 rotates relative to the frame 1 around the support structure 3 under the drive of the first drive component 4 and / or the second drive component 5, it can be manifested as relative movement between the universal ball structure 31 and the groove 212. The universal ball structure 31 can meet the motion freedom requirements of the base plate 21 and also serve to support the movable bracket 2.

[0028] For example, the omnidirectional ball structure 31 can be assembled to the base frame 11 by means of a detachable connection such as threads.

[0029] Furthermore, in some embodiments, the movable bracket 2 further includes a first side plate 22 and a second side plate 23 that are bent from the outer periphery of the base plate 21 and extend in a direction away from the base plate 21 along a first direction, the first side plate 22 and the second side plate 23 being perpendicular to each other; the frame 1 further includes a first frame 12 and a second frame 13 that are bent from the outer periphery of the base frame 11 and extend in a direction away from the base frame 11 along a first direction, the first frame 12 and the second frame 13 being perpendicular to each other, the first side plate 22 and the first frame 12 being spaced apart relative to each other in a direction parallel to the second axis of rotation, the second side plate 23 and the second frame 13 being spaced apart relative to each other in a direction parallel to the first axis of rotation; the first driving assembly 4 includes a first magnetic structure 41 fixedly mounted on the first side plate 22 and a first coil 42 fixedly mounted on the first frame 12; the second driving assembly 5 includes a second magnetic structure 51 fixedly mounted on the second side plate 23 and a second coil 52 fixedly mounted on the second frame 13.

[0030] Specifically, since the first coil 42 is fixedly mounted on the first frame 12 of the frame 1, and the first magnetic structure 41 is fixedly mounted on the first side plate 22 of the movable bracket 2, the first magnetic structure 41 and the first coil 42 are arranged relatively spaced apart along a direction parallel to the second axis of rotation. When the first coil 42 is energized, the first coil 42 and the first magnetic structure 41 interact, allowing them to move relative to each other. The force between the first magnetic structure 41 and the first coil 42 can then drive the first side plate 22 to move relative to the first frame 12, thereby causing the movable bracket 2 to move relative to the frame 1. Similarly, the interaction of the second coil 52 and the second magnetic structure 51 can drive the second side plate 23 to move relative to the second frame 13, thereby causing the movable bracket 2 to move relative to the frame 1.

[0031] In some specific embodiments, a corner may be provided at the connection between the first side plate 22 and the second side plate 23, so that the movable bracket 2 is smoother at the corner.

[0032] For example, the first magnetic structure 41 can be a magnet, a steel magnet, a magnetite, etc.

[0033] For example, the second magnetic structure 51 can be a magnet, a steel magnet, a magnetite, etc.

[0034] Furthermore, in some embodiments, the magnetization direction of the first magnetic structure 41 and the second magnetic structure 51 is parallel to the first direction, the first coil 42 and the second coil 52 are ring coils, and the central axis of the first coil 42 is perpendicular to the first frame 12, and the central axis of the second coil 52 is perpendicular to the second frame 13.

[0035] Specifically, according to the left-hand rule, when the first coil 42 is energized, it receives an Ampere force along the first direction, driving the first magnetic structure 41 to move relative to the first coil 42 along the first direction. This, in turn, drives the first side plate 22 to move relative to the first frame 12 along the first direction, thereby driving the movable bracket 2 to rotate relative to the frame 1 along the first axis. Similarly, when the second coil 52 is energized, it receives an Ampere force along the first direction, driving the second magnetic structure 51 to move relative to the second coil 52 along the first direction. This, in turn, drives the second side plate 23 to move relative to the second frame 13 along the first direction, thereby driving the movable bracket 2 to rotate relative to the frame 1 along the second axis. When the first coil 42 and the second coil 52 are energized simultaneously, the magnitude and direction of the Ampere force along the first direction on the first coil 42 are determined based on the magnitude and direction of the current. At the same time, the magnitude and direction of the Ampere force along the first direction on the second coil 52 are determined. Thus, the magnitude of the driving force on the first side plate 22 and the second side plate 23 are determined, and then the magnitude and direction of the driving force on the movable bracket 2 are determined. This allows us to determine along which rotation axis the movable bracket 2 rotates relative to the frame 1 (the rotation axis passes through the support structure 3 and is parallel to the base surface), thereby achieving anti-shaking in the preset direction and at the preset angle.

[0036] Understandably, in the actual process, the direction and angle of stabilization required are known in advance. Therefore, in reality, the stabilization mechanism 10 determines the magnitude and direction of the current of the first coil 42 and the second coil 52 based on the preset direction and angle of stabilization, so that the rotation of the movable bracket 2 relative to the frame 1 meets the stabilization requirements.

[0037] Furthermore, in some embodiments, the first frame 12 has a first slot 121 extending in a direction parallel to the second rotation axis, and the second frame 13 has a second slot 131 extending in a direction parallel to the first rotation axis. The first coil 42 is fixedly assembled in the first slot 121, and the second coil 52 is fixedly assembled in the second slot 131. This allows for the fixed assembly of the first coil 42 on the first frame 12 and the fixed assembly of the second coil 52 on the second frame 13. Moreover, since the first slot 121 and the second slot 131 are interconnected, the first coil 42 can interact with the first magnetic structure 41, and the second coil 52 can interact with the second magnetic structure 51.

[0038] Furthermore, in some embodiments, the first side plate 22 has a first mounting groove 221 extending along a direction parallel to the second rotation axis, and the second side plate 23 has a second mounting groove 231 extending along a direction parallel to the first rotation axis. The first magnetic structure 41 is fixedly mounted in the first mounting groove 221, and the second magnetic structure 51 is fixedly mounted in the second mounting groove 231. The first magnetic structure 41 and the first coil 42 are arranged relatively spaced apart along a direction parallel to the second rotation axis, and the second magnetic structure 51 and the second coil 52 are arranged relatively spaced apart along a direction parallel to the first rotation axis. In this way, the first magnetic structure 41 can be fixedly mounted in the first side plate 22, and the second magnetic structure 51 can be fixedly mounted in the second side plate 23. Moreover, since the first mounting groove 221 extends along a direction parallel to the first rotation axis, the first magnetic structure 41 and the first coil 42 can interact; and since the second mounting groove 231 extends along a direction parallel to the second rotation axis, the second magnetic structure 51 and the second coil 52 can interact.

[0039] Furthermore, in some embodiments, the first driving assembly 4 further includes a first circuit board 43 located on the side of the first coil 42 facing away from the first magnetic structure 41 in a direction parallel to the second rotating axis, and the first circuit board 43 is attached to the side of the first frame 12 facing away from the first side plate 22 in a direction parallel to the second rotating axis; the second driving assembly 5 further includes a second circuit board 53 located on the side of the second coil 52 facing away from the second magnetic structure 51 in a direction parallel to the first rotating axis, and the second circuit board 53 is attached to the side of the second frame 13 facing away from the second side plate 23 in a direction parallel to the first rotating axis; the first coil 42 and the first circuit board 43 are electrically connected, and the second coil 52 and the second circuit board 53 are electrically connected.

[0040] Specifically, the first circuit board 43 can energize the first coil 42, and the second circuit board 53 can energize the second coil 52. Since the first coil 42 is fixedly mounted within the first recess 121, the projection of the first circuit board 43 along the direction parallel to the second axis of rotation can completely cover the projection of the first coil 42 along the same direction. Furthermore, the first circuit board 43 can be fitted against the outer side of the first frame 12, thereby optimizing the spatial layout. Similarly, since the second coil 52 is fixedly mounted within the second recess 131, the projection of the second circuit board 53 along the direction parallel to the first axis of rotation can completely cover the projection of the second coil 52 along the same direction. Furthermore, the second circuit board 53 can be fitted against the outer side of the second frame 13, thereby optimizing the spatial layout.

[0041] For example, the first circuit board 43 and the second circuit board 53 can be flexible circuit boards.

[0042] In some specific embodiments, since the first frame 12 and the second frame 13 are vertically connected, and the first circuit board 43 is attached to the outside of the first frame 12 and the second circuit board 53 is attached to the outside of the second frame 13, the first circuit board 43 and the second circuit board 53 can be integrally connected and the connection point can correspond to the connection point of the first frame 12 and the second frame 13.

[0043] Furthermore, when the lens module 20 requires image stabilization, image stabilization can be achieved by energizing the first coil 42 and / or the second coil 52, causing the movable bracket 2 to rotate relative to the frame 1, at which point the movable bracket 2 moves away from its initial position. Therefore, when the lens module 20 is not working, the movable bracket 2 needs to return to its initial position. This can be achieved by applying a reverse current to the first coil 42 and / or the second coil 52, causing the movable bracket 2 to return to its initial position, thus facilitating the next image stabilization requirement.

[0044] In some embodiments, the first drive assembly 4 may further include a first metal plate 44 mounted on the side of the first circuit board 43 facing away from the first coil 42 in a direction parallel to the second axis of rotation; the second drive assembly 5 further includes a second metal plate 54 mounted on the side of the second circuit board 53 facing away from the second magnetic structure 51 in a direction parallel to the first axis of rotation. In this case, not only can the reset be controlled by applying a reverse current, but also, even without energizing the first coil 42 and the second coil 52, the movable bracket 2 can be returned to its initial position by the magnetic attraction force of the first metal plate 44 and the first magnetic structure 41, and / or by the magnetic attraction force of the second metal plate 54 and the second magnetic structure 51. Furthermore, by controlling the first metal plate 44 and the second metal plate 54 instead of the reverse current, costs can be saved and power consumption avoided. Additionally, by utilizing the magnetic attraction force of the first metal plate 44 and the first magnetic structure 41, and the magnetic attraction force of the second metal plate 54 and the second magnetic structure 51, the daily stability of the movable bracket 2 can be maintained when the anti-shake mechanism 10 is not working.

[0045] Furthermore, in some embodiments, the movable bracket 2 rotates by energizing the first coil 42 and / or the second coil 52 to achieve anti-shake, and then returns to its initial position by the first metal plate 44 and / or the second metal plate 54. In practice, when the first coil 42 is energized and the second coil 52 is not energized, only the first side plate 22 of the movable bracket 2 is subjected to force, and the movable bracket 2 rotates along the first axis of rotation. At this time, to return to the initial position, the restoring force between the first metal plate 44 and the first magnetic structure 41 has a relatively ideal curve, allowing the movable bracket 2 to return to the initial position well. Similarly, when only the second coil 52 is energized, the movable bracket 2 can also return to the initial position well, which will not be elaborated here. However, when the first coil 42 and the second coil 52 are energized at the same time, the first side plate 22 and the second side plate 23 of the movable bracket 2 will be subjected to force simultaneously, and the movable bracket 2 will rotate along any other axis of rotation. At this time, to return to the initial position, the restoring force will have some deviation and will not be as ideal as the above two situations, that is, crosstalk will occur, which may cause a decrease in control accuracy. Therefore, in some embodiments, this interference can be supplemented by an algorithm, specifically by adjusting the characteristics of the anti-shake mechanism 10, so that when the first coil 42 and the second coil 52 are energized at the same time, the movement deviation of the movable bracket 2 relative to the frame 1 is within an acceptable range.

[0046] For example, the first metal sheet 44 and the second metal sheet 54 can be recovery steel sheets.

[0047] Furthermore, in some embodiments, there is a gap 6 between the base plate 21 and the base frame 11; the base plate 21 has an opening 211 that extends along a first direction, and the electrical connection structure 201 of the lens module 20 is connected to the external circuit in sequence through the opening 211 and the gap 6.

[0048] Specifically, the lens module 20 is mounted on one side of the base plate 21 along the first direction, and the gap 6 is located on the other side of the base plate 21 along the first direction. An opening 211 is provided on the base plate 21, so that the electrical connection structure 201 of the lens module 20 can extend from one side of the base plate 21 to the other side through the opening 211, thereby being used for electrical connection with the outside.

[0049] In some specific embodiments, the base plate 21 may have multiple openings 211, and the openings 211 and the lens module 20 are configured one-to-one.

[0050] For example, the electrical connection structure 201 can be a flexible circuit board, etc.

[0051] Furthermore, in some specific embodiments, the frame 1 further includes a third side plate spaced apart from the first side plate 12 and a third side plate spaced apart from the second side plate 13. The movable bracket 2 further includes a third side plate spaced apart from the first side plate 22 and a fourth side plate spaced apart from the second side plate 23. The bottom frame 11, the first side plate 12, the second side plate 13, the third side plate, and the fourth side plate enclose a space for accommodating the movable bracket 2; the bottom plate 21, the first side plate 22, the second side plate 23, the third side plate, and the fourth side plate enclose a space for accommodating the lens module 20.

[0052] Furthermore, in some specific embodiments, since the third side plate and the fourth side plate do not need to be fitted with coils, the thickness of the third side plate and the fourth side plate can be relatively thinner than that of the first side plate 22 and the second side plate 23, and the extension length of the third side plate and the fourth side plate can be relatively shorter than that of the first side plate 22 and the second side plate 23.

[0053] A second aspect of the present invention provides an electronic device, which includes an electronic device body 30 and a stabilization mechanism 10; the electronic device body 30 has an assembly frame 301, and the stabilization mechanism 10 is assembled in the assembly frame 301.

[0054] Specifically, the electronic device can be a mobile phone, tablet, etc. The electronic device body 30 can be the casing, other functional components, etc. of the electronic device. The multiple lens modules 20 of the electronic device can be directly mounted on the movable bracket 2 of the image stabilization mechanism 10, so that the electronic device only needs one image stabilization mechanism 10 to simultaneously stabilize multiple lens modules 20, thereby reducing the number of image stabilization mechanisms 10 in the whole device, reducing the space occupied by the image stabilization mechanisms 10 in the whole device, and helping to reduce the size of the electronic device; at the same time, it can also improve the stability of image stabilization and the consistency of multi-lens image stabilization performance, better improve the shooting effect, and expand applications such as multi-lens image fusion. In addition, the casing can form a mounting frame 301, and the image stabilization mechanism 10 can be mounted in the mounting frame 301, so that the bottom frame 11 and the bottom side of the mounting frame 301 are in contact.

[0055] Furthermore, in some specific embodiments, the electronic device may also include a protective cover spaced apart from the bottom frame 11, which covers the assembly frame 301, thereby protecting the image stabilization mechanism 10 from external dust and moisture. Additionally, the protective cover may be made of a light-transmitting material, thus enabling the lens module 20 to operate.

[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0057] The above is a description of the technical solution provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
