[0001] The present invention relates to the technical field of camera devices, in particular to a focusing and anti-shake structure and a focusing and anti-shake camera. Background Art

[0002] With the progress of science and the development of technology, existing mobile electronic devices such as mobile phones, tablet computers and notebooks have witnessed rapid development. A micro camera module is an important functional module of the above-mentioned mobile electronic devices. In order to obtain better shooting effects, existing micro camera modules generally have a focusing function and an anti-shake function.

[0003] However, the focusing structure of existing micro camera modules mainly uses a voice coil motor as a lens driving device to adjust the focal length of the camera. However, the structure of the voice coil motor is complex, which is not conducive to production, and its volume is too large, not meeting the requirements of portability and miniaturization. In addition, the existing anti-shake structure is complex and the assembly process is cumbersome, greatly increasing the manufacturing cost of enterprises. Summary of the Invention

[0004] The object of the present invention is to provide a focusing and anti-shake structure and a focusing and anti-shake camera, the focusing structure of which is simple and the focusing process is stable, suitable for realizing the miniaturization and microminiaturization of the structure, having good anti-shake performance and capable of realizing the directional jitter correction in the X-Y plane, having relatively large structural rigidity, and being able to effectively simplify the conductive process of the coil and reduce the overall height of the product.

[0005] In order to achieve the above object, the present invention discloses a focusing and anti-shake structure, which includes a carrier, a magnetic component, a first driving mechanism, a second driving mechanism, a suspension mechanism, a mounting seat and a conductive terminal component. The carrier is used for mounting a camera body. The first driving mechanism includes a first frame and a first coil disposed around the carrier. The carrier is located within the first frame. The magnetic component is mounted on the first frame and distributed around the carrier. The first coil corresponds to the magnetic component. When the first coil is energized, a magnetic induction is generated with the magnetic component to push the carrier to move along the Z-axis direction. The second driving mechanism includes a second frame and a second coil assembly. The first frame is located within the second frame. The second coil assembly is disposed around the magnetic component and corresponds to the magnetic component. When the second coil assembly is energized, a magnetic induction is generated with the magnetic component to push the carrier to move along the X-axis direction and / or along the Y-axis direction. The suspension mechanism is used to suspend the carrier and the first frame together within the second frame. When neither the first coil nor the second coil assembly is energized, the carrier is in an initial state, and the suspension mechanism constantly provides an elastic force to reset the carrier to the initial state along the Z-axis direction, X-axis direction and Y-axis direction respectively. The suspension mechanism and the second coil assembly are respectively mounted on the mounting seat, and the conductive terminal component is embedded in the mounting seat. The conductive terminal component is electrically connected to the first coil and the second coil assembly respectively.

[0006] Compared with the prior art, when the first coil of the present invention is turned on, it generates magnetic induction with the magnetic component to drive the carrier stage to move in the Z-axis direction. When the second coil assembly is turned on, it generates magnetic induction with the magnetic component to drive the carrier stage to move in the X-axis direction and / or in the Y-axis direction respectively. The suspension mechanism constantly provides an elastic force to reset the carrier stage to the initial state in the Z-axis direction, X-axis direction, and Y-axis direction respectively. The conductive terminal assembly is embedded in the mounting seat, and the conductive terminal assembly is electrically connected to the first coil and the second coil assembly respectively. On the one hand, the carrier stage is driven to move in the Z-axis direction by means of magnetic induction to achieve the focusing of the camera body. The driving method is simple and the driving structure occupies a small volume, which is suitable for miniaturizing and micro-miniaturizing the entire focusing and anti-shake structure. Moreover, the carrier stage is subjected to an elastic force to be reset to the initial state in the Z-axis direction, effectively ensuring the stability of the focusing process. On the other hand, the carrier stage and the first frame are jointly suspended in the second frame, and the carrier stage is subjected to an elastic force to be reset to the initial state in the X-axis direction and Y-axis direction, ensuring that the carrier stage can effectively offset jitter through the suspension mechanism. On the third hand, the carrier stage is driven to move in the X-axis direction and Y-axis direction by means of magnetic induction, and the directional jitter correction of the carrier stage in the X-Y plane is realized through the magnetic induction driving method, further improving the anti-shake performance of the focusing and anti-shake structure. On the fourth hand, the conductive terminal assembly is embedded in the mounting seat to strengthen the rigidity of the mounting seat, and there is no need to electrically connect the coil through a wire, effectively simplifying the conductive process of the coil.

[0027] In order to describe in detail the technical content, structural features, achieved purposes and effects of the present invention, the following is described in detail in conjunction with the embodiments and with reference to the drawings.

[0028] Please refer to Figure 1 As shown, the focusing and anti-shake camera 1000 of this embodiment includes a camera body (not shown in the figure), a housing 200 and a focusing and anti-shake structure 100, and the focusing and anti-shake structure 100 is arranged in the housing 200. The focusing and anti-shake structure 100 is used to adjust the position of the camera body in the Z-axis direction to achieve the focusing function, and is also used to buffer the jitter interference of the camera body to achieve the anti-shake function, and can also perform active jitter correction on the camera body in the X-Y plane to ensure the normal operation of the camera body.

[0029] Please refer to Figures 2 - 4 As shown, the focusing and anti-shake structure 100 of this embodiment includes a carrier 10, a magnetic component, a first driving mechanism, a second driving mechanism, a suspension mechanism 50, a mounting seat 60, and a conductive terminal component 70. Among them, the carrier 10 is provided with a mounting groove 11 matching the camera body, and the camera body is fixed on the carrier 10 through the mounting groove 11.

[0030] The first driving mechanism includes a first frame 31 and a first coil 32 wound around the carrier 10. The first coil 32 is fixed on the side wall of the carrier 10 by winding. The first frame 31 has a rectangular ring structure. The carrier 10 is located inside the first frame 31 and has a certain gap with the first frame 31. The magnetic component is installed on the first frame 31 and distributed around the circumference of the carrier 10. The first coil 32 corresponds to the magnetic component. When the first coil 32 is energized, it generates magnetic induction with the magnetic component to push the carrier 10 to move in the Z-axis direction.

[0031] Preferably, the magnetic component includes two magnetic members. Each magnetic member includes two magnetic monomers 20 arranged oppositely. One of the two magnetic members is arranged along the X-axis direction so that the two sides of the carrier 10 along the X-axis direction are respectively corresponding to magnetic monomers 20. The other of the two magnetic members is arranged along the Y-axis direction so that the two sides of the carrier 10 along the Y-axis direction are respectively corresponding to magnetic monomers 20. First embedding grooves 311 for embedding and fixing the magnetic monomers 20 are provided on the four side frames of the first frame 31. At this time, the four side frames of the first frame 31 are all embedded with magnetic monomers 20. Assuming that the center position of the carrier 10 is the origin of the X-Y plane, there is a magnetic monomer 20 corresponding to the positive X-axis direction, negative X-axis direction, positive Y-axis direction, and negative Y-axis direction of the carrier 10 respectively.

[0032] Preferably, the four magnetic units are at the same height and correspond to the height where the first coil 32 is located. When the first coil 32 is energized, the first coil 32 generates current, and magnetic induction is generated between the first coil 32 and all the magnetic monomers 20. The first coil 32 can move relative to the magnetic component in the Z-axis direction under the action of magnetic force, thereby pushing the carrier 10 to move synchronously in the Z-axis direction. Specifically, by changing the current direction of the first coil 32, the carrier 10 can be pushed to move in the positive or negative Z-axis direction. By controlling the current magnitude of the first coil 32, the moving distance of the carrier can be controlled, thereby controlling the focusing parameters of the camera body.

[0033] It should be noted that by changing the number of turns of the first coil 32, the magnetic induction intensity between the first coil 32 and all the magnetic monomers 20 can be adjusted under the condition of the same current magnitude, so as to adjust the force received by the carrier 10 in the Z-axis direction.

[0034] Please refer to Figures 2 - 5As shown in the figure, the second driving mechanism of this embodiment includes a second frame 41 and a second coil assembly. The second frame 41 has a rectangular ring structure. The first frame 31 is located inside the second frame 41 and has a certain gap from the second frame 41. Preferably, as Figure 5 shown, the carrier table 10, the first frame 31, the first coil 32 and the second frame 41 are coaxially arranged. The central axes of the carrier table 10, the first frame 31, the first coil 32 and the second frame 41 are all arranged along the Z-axis direction, which is convenient for assembly and adjustment. The second coil assembly is arranged on the periphery of the magnetic assembly and corresponds to the magnetic assembly. When the second coil assembly is energized, a magnetic induction is generated with the magnetic assembly to push the carrier table 10 to move along the X-axis direction and / or along the Y-axis direction respectively.

[0035] Preferably, the second coil assembly includes two second coil members. Each second coil member includes two second coils 42. Two second coils 42 in one of the two second coil members correspond to two magnetic monomers 20 arranged along the X-axis direction one by one, and two second coils 42 in the other of the two second coil members correspond to two magnetic monomers 20 arranged along the Y-axis direction one by one. At this time, one second coil 42 corresponds to the outside of each magnetic unit, that is, one second coil 42 corresponds to the positive X-axis direction, the negative X-axis direction, the positive Y-axis direction and the negative Y-axis direction outside the carrier table 10. The second coil 42 corresponds to the magnetic unit in the corresponding direction. Specifically, the second coil 42 is located on the side of the magnetic unit in the corresponding direction away from the carrier table 10.

[0036] When a single second coil 42 is energized, a current is generated in the second coil 42. A magnetic induction is generated between the second coil 42 and the corresponding magnetic monomer 20. The second coil 42 can move relative to the magnetic unit along the positive or negative direction of the X-axis / Y-axis under the action of the magnetic force. Taking the second coil 42 arranged on the positive X-axis side of the carrier table 10 as an example for illustration, when the second coil 42 is energized, the first frame 31 can move relative to the second coil 42 along the positive X-axis direction under the action of the magnetic force, thereby pushing the carrier table 10 to move synchronously along the positive X-axis direction to actively calibrate the jitter of the carrier table 10 in the positive X-axis direction. Specifically, by changing the current direction of the second coil 42, the carrier table 10 is pushed to move forward or backward along the X-axis. By controlling the current magnitude of the second coil 42, the moving distance of the carrier seat is controlled, so as to control the jitter correction of the camera body in the X-Y plane.

[0037] It should be noted that the situations where the second coil 42 is located in the negative X-axis direction, positive Y-axis direction, and negative Y-axis direction outside the carrier 10 are the same as the above description and will not be elaborated here. When the second coil 42 located on one side of the positive X-axis / negative X-axis of the carrier 10 and the second coil 42 located on one side of the positive Y-axis / negative Y-axis of the carrier 10 are energized respectively, precise active movement of the carrier 10 in each quadrant of the X-Y plane can be achieved, so as to realize precise active jitter calibration of the carrier 10 in the X-Y plane. It should be noted that the energization direction of the coil and the direction of the force of the magnetic monomer 20 are related to the current direction on the coil and the polarity of the magnetic monomer 20. The magnetism of the magnetic monomer 20 corresponding to one side of the coil is set according to actual needs so that the generated force meets the actual needs.

[0038] Please refer to Figures 2 - 4 、 Figures 6 - 8 As shown, the suspension mechanism 50 of this embodiment is used to suspend the carrier 10 and the first frame 31 together in the second frame 41. When the first coil 32 and the second coil assembly are not conducted, the carrier 10 is in the initial state, and the suspension mechanism 50 constantly provides elastic forces to reset the carrier 10 along the Z-axis direction, X-axis direction, and Y-axis direction to the initial state respectively.

[0039] The suspension mechanism 50 and the four second coils 42 are respectively installed on the mounting seat 60. There is a certain gap between the second frame 41 and the mounting seat 60, and the housing 200 covers the mounting seat 60. Preferably, second embedding grooves 61 for fixing the second coils 42 are provided on four sides of the mounting seat 60. At this time, the second coils 42 are embedded and fixed on four sides of the mounting seat 60. Specifically, one second coil 42 is correspondingly fixed in the positive X-axis direction, negative X-axis direction, positive Y-axis direction, and negative Y-axis direction of the mounting seat 60.

[0040] The conductive terminal assembly 70 is electrically connected to the first coil 32 and the second coil assembly respectively, and the conductive terminal assembly 70 is embedded in the mounting seat 60. Preferably, the mounting seat 60 is a plastic part, and the conductive terminal assembly 70 is embedded and fixed in the mounting seat 60 when the mounting seat 60 is injection-molded, that is, the conductive terminal assembly 70 and the mounting seat 60 are of an integral structure, so as to simplify the installation process of the conductive terminal assembly 70 and enhance the rigidity of the mounting seat 60.

[0041] Preferably, the suspension mechanism 50 includes two separate suspension components 51. The two suspension components 51 are located on the same horizontal plane, and the positional relationship between the two suspension components 51 is separated by 180° with the central axis of the carrier as the axis.

[0042] The conductive terminal assembly 70 includes two first conductive terminals 71 and a second conductive terminal assembly. One of the two first conductive terminals 71 is electrically connected to one of the suspension assemblies 51, and the other is electrically connected to the other suspension assembly 51. The positive electrode of the first coil 32 is electrically connected to one of the suspension assemblies 51, and the negative electrode of the first coil 32 is electrically connected to the other suspension assembly 51. The second conductive terminal assembly is electrically connected to the second coil assembly. The first coil 32 conducts electricity with the outside through the suspension assembly 51 and the first conductive terminal 71, without the need for wire routing, effectively simplifying the layout.

[0043] The second conductive terminal assembly includes four second conductive terminal members corresponding to the second coils 42 one by one. Each second conductive terminal member includes two second conductive terminals 72. One of the two second conductive terminals 72 is electrically connected to the positive electrode of the second coil 42, and the other is electrically connected to the negative electrode of the second coil 42. The second coil 42 conducts electricity with the outside through the second conductive terminal 72, without the need for wire routing, effectively simplifying the layout.

[0044] The suspension assembly 51 includes a first cantilever assembly, a first fixing piece 512, a second cantilever member, and a second fixing piece 514 connected in sequence. The first cantilever assembly is respectively connected to the carrier 10 and the first fixing piece 512. The first fixing piece 512 is connected to the first frame 31. The second fixing piece 514 is connected to the second frame 41. The first cantilever assembly is used to provide an elastic force for resetting the carrier 10 to the initial state in the Z-axis direction. The second cantilever member is used to provide an elastic force for resetting the carrier 10 to the initial state in the X-axis direction and an elastic force for resetting the carrier 10 to the initial state in the Y-axis direction. Preferably, the first cantilever assembly, the first fixing piece 512, the second cantilever member, the second fixing piece 514, and the third fixing piece 515 are integrally structured to reduce the number of components of the suspension assembly 51 and effectively reduce the assembly process and assembly difficulty. Of course, in other embodiments, the first cantilever assembly, the first fixing piece 512, the second cantilever member, the second fixing piece 514, and the third fixing piece 515 can be discrete structures to meet more usage requirements, which will not be elaborated here.

[0045] Specifically, the first cantilever assembly includes two first cantilevers 511, which are arranged in a snake shape. The first cantilevers 511 are respectively connected to the carrier 10 and the first frame 31. Preferably, each corner of the upper surface of the carrier 10 is connected to a first cantilever 511, and the four first cantilevers 511 jointly suspend the carrier 10 in a balanced manner within the first frame 31 to provide an elastic force for resetting the carrier 10 to the initial state along the Z-axis direction. When the first coil 32 pushes the carrier 10 to move forward or backward along the Z-axis, it is necessary to overcome the elastic force of the first cantilever assembly. This elastic force is used to limit the moving speed and moving distance of the carrier 10 along the Z-axis direction, avoiding damage to the camera body and focusing failure caused by excessive or over-limit movement, and effectively improving the stability of the focusing process.

[0046] The second cantilever member includes two second cantilevers 513. The second cantilevers 513 are connected to the first fixing piece 512. One of the two second cantilevers 513 is arranged outside the first frame 31 along the X-axis / Y-axis direction and is respectively connected to the first fixing piece 512 and the second fixing piece 514 to provide an elastic force for resetting the carrier 10 to the initial state along the X-axis / Y-axis direction. The suspension assembly 51 further includes a third fixing piece 515. The other of the two second cantilevers 513 is arranged outside the first frame 31 along the Y-axis / X-axis direction and is respectively connected to the second fixing piece 514 and the third fixing piece 515 to provide an elastic force for resetting the carrier 10 to the initial state along the Y-axis / X-axis direction.

[0047] At this time, there is a second cantilever 513 corresponding to each of the four side frames of the first frame 31. Under the elastic restraint of the four second cantilevers 513, when the second coil 42 is not energized, the first frame 31 is constantly restricted to the origin position in the X-Y plane. On the one hand, when the first frame 31 and the carrier 10 vibrate, the four second cantilevers 513 can limit the vibration amplitude and quickly eliminate the vibration, effectively achieving the anti-shake function; when external vibration is transmitted from the second frame 41 to the first frame 31 and the carrier 10, the vibration needs to pass through the four second cantilevers 513 first. The four second cantilevers 513 can quickly limit the vibration amplitude and quickly cancel the vibration, effectively achieving the anti-shake function.

[0048] When the second coil 42 pushes the carrier 10 to move along the X-axis direction and / or the Y-axis direction, it is necessary to overcome the elastic force of the second cantilever 513 assembly corresponding to the axis direction. This elastic force is used to limit the moving speed and moving distance of the carrier 10 along the X-axis direction and / or the Y-axis direction, avoiding damage to the camera body and focusing failure caused by excessive or over-limit movement, and effectively improving the stability of the focusing process.

[0049] Further, the suspension mechanism 50 further includes a third cantilever assembly. The third cantilever assembly is disposed on the other side of the carrier 10 opposite to the first cantilever assembly, and the third cantilever assembly is respectively connected to the carrier 10 and the first frame 31. Specifically, the third cantilever assembly includes four third cantilevers 52 evenly arranged in a clockwise or counterclockwise direction, and the third cantilever 52 is arranged in a snake shape. The third cantilevers 52 are respectively connected to the carrier 10 and the first frame 31. Preferably, each corner of the lower surface of the carrier 10 is connected to a third cantilever 52, and the four third cantilevers 52 jointly and stably suspend the carrier 10 within the first frame 31 to cooperate with the four first cantilevers 511 to further provide an elastic force for resetting the carrier 10 to the initial state in the Z-axis direction, so as to further improve the stability of the focusing process.

[0050] It should be noted that in this embodiment, the first frame 31 and the second frame 41 are both described as rectangular ring structures. In other embodiments, the first frame 31 and the second frame 41 can both be other polygonal ring structures. At this time, a magnetic monomer 20 needs to be correspondingly arranged on each side frame of the first frame 31, and the respective cantilevers of the suspension mechanism 50 need to be adaptively modified, which will not be elaborated here.

[0051] Please refer to Figures 2 - 4 、 Figure 6 and Figure 8 As shown in, the focusing and anti-shake structure 100 of this embodiment further includes a position detection component. The position detection component is used to detect the moving distance of the carrier 10 in the X-axis direction and the moving distance in the Y-axis direction. Specifically, the position detection component includes two position sensors 80. The position sensor 80 can be an electronic component such as a Hall sensor. One position sensor 80 is used to detect the moving distance of the carrier 10 in the X-axis direction, and the other position sensor 80 is used to detect the moving distance of the carrier 10 in the Y-axis direction. By accurately detecting the displacements of the carrier 10 in the X-axis direction and the Y-axis direction through the position sensors 80, under the control of the controller, precise anti-shake control of the carrier 10 can be performed.

[0052] Preferably, the conductive terminal assembly 70 further includes two third conductive terminal assemblies. Each third conductive terminal assembly includes a plurality of third conductive terminals 73. The third conductive terminals 73 in each group of third conductive terminal assemblies are used to electrically connect a position sensor 80. The position sensor 80 is externally conductive through the third conductive terminals 73, eliminating the need for wire routing, effectively simplifying the layout.

[0053] Combined with Figures 1 - 8, the first coil 32 of the present invention is turned on to generate magnetic induction with the magnetic component, so as to drive the carrier 10 to move along the Z-axis direction. The second coil assembly is turned on to generate magnetic induction with the magnetic component, so as to drive the carrier 10 to move along the X-axis direction and / or along the Y-axis direction respectively. The suspension mechanism 50 always provides an elastic force to reset the carrier 10 to the initial state along the Z-axis direction, X-axis direction and Y-axis direction respectively. On the one hand, the carrier 10 is driven to move along the Z-axis direction by using the magnetic induction method to achieve the focusing of the camera body. The driving method is simple and the driving structure occupies a small volume, which is suitable for miniaturizing and micro-miniaturizing the entire focusing and anti-shake structure 100. Moreover, the carrier 10 is subjected to the elastic force to be reset to the initial state along the Z-axis direction, effectively ensuring the stability of the focusing process. On the other hand, the carrier 10 and the first frame 31 are jointly suspended in the second frame 41, and the carrier 10 is subjected to the elastic force to be reset to the initial state along the X-axis direction and Y-axis direction, ensuring that the carrier 10 can effectively offset the jitter through the suspension mechanism 50. On the third hand, the carrier 10 is driven to move along the X-axis direction and Y-axis direction by using the magnetic induction method, and the directional jitter correction of the carrier 10 on the X-Y plane is realized through the magnetic induction driving method, further improving the anti-shake performance of the focusing and anti-shake structure 100. On the fourth hand, the conductive terminal assembly 70 is embedded in the mounting seat 60 to enhance the rigidity of the mounting seat 60, and there is no need to electrically connect the coil through a wire, effectively simplifying the conductive process of the coil. On the fifth hand, the second coil assembly is arranged on the periphery of the magnetic component, effectively reducing the overall height of the product.

[0054] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
