[0025] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0026] See also Figure 1 As shown, the focus and anti-shake camera 1000 of this embodiment includes a camera body (not shown), a housing 200 and a focus and anti-shake structure 100, and the focus and anti-shake structure 100 is arranged in the housing 200. The focus and anti-shake structure 100 is used to adjust the position of the camera body in the Z-axis direction to achieve the focus function, and is also used to buffer the jitter interference of the camera body to achieve the anti-shake function, and can also actively correct the jitter of the camera body on the XY plane to ensure that the camera body can work normally.

[0027] See also Figure 2-Figure 4 As shown, the focus and anti-shake structure 100 of this embodiment includes a supporting platform 10, a magnetic component, a first driving mechanism, a second driving mechanism and a suspension mechanism 50, wherein the supporting platform 10 is provided with a mounting groove 11 matching the camera body, and the camera body is fixed on the supporting platform 10 through the mounting groove 11.

[0028] The first driving mechanism includes a first frame 31 and a first coil 32 arranged in a ring around the carrier platform 10. The first coil 32 is fixed to the side wall of the carrier platform 10 by winding. The first frame 31 is a rectangular ring structure. The carrier platform 10 is located in 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 is distributed on the surrounding side of the carrier platform 10. The first coil 32 corresponds to the magnetic component. The first coil 32 is turned on and generates magnetic induction with the magnetic component to push the carrier platform 10 to move along the Z-axis direction.

[0029] Preferably, the magnetic assembly includes two magnetic components, and the magnetic components include two magnetic monomers 20 arranged opposite to each other. One of the two magnetic components is arranged along the X-axis direction, so that the two sides of the carrier 10 along the X-axis direction correspond to the magnetic monomers 20 respectively, and the other of the two magnetic components is arranged along the Y-axis direction, so that the two sides of the carrier 10 along the Y-axis direction correspond to the magnetic monomers 20 respectively. The four frames of the first frame 31 are all provided with embedding grooves 311 for the magnetic monomers 20 to be embedded and fixed. At this time, the four frames of the first frame 31 are all embedded with magnetic monomers 20. Assuming that the axis position of the carrier 10 is the origin of the XY plane, the positive direction of the X-axis, the negative direction of the X-axis, the positive direction of the Y-axis, and the negative direction of the Y-axis of the carrier 10 each correspond to a magnetic monomer 20.

[0030] Preferably, the four magnetic units are located at the same height and correspond to the height of the first coil 32. When the first coil 32 is turned on, the first coil 32 generates current, and the first coil 32 generates magnetic induction with all the magnetic monomers 20. The first coil 32 is acted upon by the magnetic force and can move relative to the magnetic component along the Z-axis direction, thereby pushing the carrier 10 to move synchronously along the Z-axis direction. Specifically, by changing the current direction of the first coil 32, the carrier 10 is pushed to move forward or backward along the Z-axis, and by controlling the current size of the first coil 32, the moving distance of the carrier is controlled, thereby controlling the focus parameters of the camera body.

[0031] 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 units 20 can be adjusted under the same current to adjust the force applied to the support platform 10 along the Z-axis direction.

[0032] See also Figure 2-Figure 5 As shown, the second driving mechanism of this embodiment includes a second frame 41 and a second coil assembly. The second frame 41 is a rectangular ring structure. The first frame 31 is located in the second frame 41 and has a certain gap with the second frame 41. Preferably, as Figure 5As shown, the carrier 10, the first frame 31, the first coil 32 and the second frame 41 are coaxially arranged, and the central axes of the carrier 10, the first frame 31, the first coil 32 and the second frame 41 are all arranged along the Z-axis direction for easy assembly and adjustment. The second coil assembly is arranged below the magnetic assembly and corresponds to the magnetic assembly. The second coil assembly is turned on and generates magnetic induction with the magnetic assembly to push the carrier 10 to move along the X-axis direction and / or along the Y-axis direction respectively.

[0033] Preferably, the second coil assembly includes two second coil components, and the second coil components include two second coils 42. The two second coils 42 in one of the two second coil components correspond to the two magnetic monomers 20 arranged along the X-axis direction, and the two second coils 42 in the other of the two second coil components correspond to the two magnetic monomers 20 arranged along the Y-axis direction. At this time, there is a second coil 42 corresponding to the bottom of each magnetic unit, that is, there is a second coil 42 corresponding to the positive direction of the X-axis, the negative direction of the X-axis, the positive direction of the Y-axis, and the negative direction of the Y-axis under the carrier 10, and the second coil 42 corresponds to the magnetic unit in the corresponding direction. Specifically, the second coil 42 is located below the magnetic unit in the corresponding direction.

[0034] When a single second coil 42 is turned on, the second coil 42 generates current, and the second coil 42 generates magnetic induction with the corresponding magnetic unit 20. The second coil 42 is affected by the magnetic force and can move relative to the magnetic unit along the positive or negative direction of the X-axis / Y-axis. Take the second coil 42 arranged in the positive direction of the X-axis below the carrier 10 as an example. When the second coil 42 is energized, the first frame 31 is affected by the magnetic force and can move relative to the second coil 42 along the positive direction of the X-axis, thereby pushing the carrier 10 to move synchronously along the positive direction of the X-axis to actively calibrate the jitter of the carrier 10 in the positive direction of the X-axis. Specifically, by changing the current direction of the second coil 42 to push the carrier 10 to move in the positive or reverse direction along the X-axis, and by controlling the current size of the second coil 42 to control the moving distance of the carrier, the camera body is controlled to correct the jitter in the XY plane.

[0035] It is worth noting that the situation where the second coil 42 is located in the negative direction of the X-axis, the positive direction of the Y-axis, and the negative direction of the Y-axis below the carrier 10 is the same as the above description and will not be elaborated here. When the second coil 42 located in the positive direction of the X-axis / negative direction of the X-axis below the carrier 10 and the second coil 42 located in the positive direction of the Y-axis / negative direction of the Y-axis below the carrier 10 are respectively energized, the carrier 10 can be accurately actively moved in each quadrant of the XY plane to achieve accurate active jitter calibration of the carrier 10 in the XY plane. It should be noted that the direction of energization of the coil is related to the direction of the force applied to the magnetic monomer 20, the direction of the current on the coil, and the polarity of the magnetic monomer 20. The magnetism of the magnetic monomer 20 corresponding to the coil side is set according to actual needs so that the generated force meets actual needs.

[0036] See also Figure 2-Figure 4 , Figure 6 and Figure 7 As shown, the suspension mechanism 50 of the present embodiment is used to suspend the support platform 10 and the first frame 31 together in the second frame 41. When the first coil 32 and the second coil assembly are not turned on, the support platform 10 is in the initial state, and the suspension mechanism 50 constantly provides elastic force to reset the support platform 10 to the initial state along the Z-axis direction, the X-axis direction and the Y-axis direction respectively.

[0037] Preferably, the suspension mechanism 50 includes a first cantilever assembly, a first fixing plate 52, a second cantilever assembly and a second fixing plate 54 connected in sequence, the first cantilever assembly is respectively connected to the load-bearing platform 10 and the first fixing plate 52, the first fixing plate 52 is connected to the first frame 31, and the second fixing plate 54 is connected to the second frame 41. The first cantilever assembly is used to provide an elastic force for resetting the load-bearing platform 10 to an initial state along the Z-axis direction, and the second cantilever assembly is used to provide an elastic force for resetting the load-bearing platform 10 to an initial state along the X-axis direction and an elastic force for resetting the load-bearing platform 10 to an initial state along the Y-axis direction. Preferably, the first cantilever assembly, the first fixing plate 52, the second cantilever assembly, the second fixing plate 54 and the third fixing plate 55 are arranged in an integrated structure to reduce the number of components of the suspension mechanism 50, and effectively reduce the assembly process and assembly difficulty. Of course, in other embodiments, the first cantilever assembly, the first fixing plate 52, the second cantilever assembly, the second fixing plate 54 and the third fixing plate 55 can be discrete structures to adapt to more usage requirements, which will not be repeated here.

[0038] Specifically, the first cantilever assembly includes four first cantilevers 51 evenly arranged in a clockwise or counterclockwise direction, and the first cantilever 51 is arranged in a snake shape. The first cantilevers 51 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 51, and the four first cantilevers 51 jointly suspend the carrier 10 in a balanced manner in the first frame 31 to provide an elastic force to reset the carrier 10 to an 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, which is used to limit the moving speed and moving distance of the carrier 10 along the Z-axis direction, to avoid damage to the camera body and focus failure due to excessive movement or excessive movement, and effectively improve the stability of the focusing process.

[0039] The second cantilever assembly includes two second cantilever members, and the second cantilever members include two second cantilevers 53, the second cantilevers 53 are connected to the first fixing plate 52, and the two second cantilevers 53 in one of the two second cantilever members are arranged on both sides of the first frame 31 along the X-axis direction, and are respectively connected to the first fixing plate 52 and the second fixing plate 54, so as to provide an elastic force to restore the carrier 10 to an initial state along the X-axis direction. The suspension mechanism 50 also includes a third fixing plate 55, and the two second cantilevers 53 in the other of the two second cantilever members are arranged on both sides of the first frame 31 along the Y-axis direction, and are respectively connected to the second fixing plate 54 and the third fixing plate 55, so as to provide an elastic force to restore the carrier 10 to an initial state along the Y-axis direction.

[0040] At this time, each of the four borders of the first frame 31 corresponds to a second cantilever 53. Under the elastic restriction of the four second cantilevers 53, when the second coil 42 is not conductive, the first frame 31 and the carrier platform 10 are constantly restricted to the origin position of the XY plane. On the one hand, when the first frame 31 and the carrier platform 10 vibrate, the four second cantilevers 53 can limit the vibration amplitude and quickly eliminate the vibration, thereby effectively achieving the anti-shake function; when external vibration is transmitted to the first frame 31 and the carrier platform 10 via the second frame 41, the vibration needs to pass through the four second cantilevers 53 first. The four second cantilevers 53 can quickly limit the vibration amplitude and quickly offset the vibration, thereby effectively achieving the anti-shake function.

[0041] When the second coil 42 pushes the carrier platform 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 component corresponding to the axial direction. The elastic force is used to limit the moving speed and distance of the carrier platform 10 along the X-axis direction and / or the Y-axis direction, avoiding damage to the camera body and focusing failure due to excessive movement or exceeding the limit, thereby effectively improving the stability of the focusing process.

[0042] Further, the focusing and anti-shake structure 100 also includes a third frame 60, which is a rectangular ring structure, the second frame 41 is located in the third frame 60, and has a certain gap with the third frame 60, the third fixing piece 55 is connected to the third frame 60, and the suspension mechanism 50 also includes a third cantilever assembly, the third cantilever assembly is arranged on the other side of the carrier 10 relative to the first cantilever assembly, and the third cantilever assembly is respectively connected to the carrier 10 and the first frame 31. Preferably, the third frame 60 is also coaxially arranged with the carrier 10, the first frame 31, the first coil 32 and the second frame 41.

[0043] Specifically, the third cantilever assembly includes four third cantilevers 56 evenly arranged in a clockwise or counterclockwise direction, and the third cantilevers 56 are arranged in a snake shape. The third cantilevers 56 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 56, and the four third cantilevers 56 together suspend the carrier 10 in a balanced manner in the first frame 31, so as to cooperate with the four first cantilevers 51 to further provide an elastic force to reset the carrier 10 to the initial state along the Z-axis direction, so as to further improve the stability of the focusing process.

[0044] It is worth noting that in this embodiment, the first frame 31, the second frame 41 and the third frame 60 are described as rectangular ring structures. In other embodiments, the first frame 31, the second frame 41 and the third frame 60 can all be other polygonal ring structures. In this case, each border of the first frame 31 needs to be correspondingly provided with a magnetic unit 20, and each cantilever of the suspension mechanism 50 needs to be adaptively modified, which is not elaborated here.

[0045] See also Figure 2-Figure 4 As shown, the focusing and anti-shake structure 100 of this embodiment also includes a mounting platform 70 and a position detection component, the second coil component and the third frame 60 are respectively arranged on the mounting platform 70, and the mounting platform 70 is fixed inside the shell 200. The position detection component is used to detect the moving distance of the carrier 10 along the X-axis direction and the moving distance along the Y-axis direction. Specifically, the position detection component includes two position sensors 80, and the position sensor 80 can be an electronic component such as a Hall sensor, one of which is used to detect the moving distance of the carrier 10 along the X-axis direction, and the other position sensor 80 is used to detect the moving distance of the carrier 10 along the Y-axis direction. The displacement of the carrier 10 in the X-axis direction and the Y-axis direction is accurately detected by the position sensor 80, and under the control of the controller, the carrier 10 can be accurately anti-shake controlled.

[0046] Combination Figure 1-Figure 7The first coil 32 of the present invention is turned on to generate magnetic induction with the magnetic component to push the carrier 10 to move along the Z-axis direction, and the second coil component is turned on to generate magnetic induction with the magnetic component to push the carrier 10 to move along the X-axis direction and / or along the Y-axis direction. The suspension mechanism 50 constantly provides elastic forces to reset the carrier 10 to the initial state along the Z-axis direction, the X-axis direction and the Y-axis direction. On the one hand, the magnetic induction method is used to push the carrier 10 to move along the Z-axis direction to achieve the focus of the camera body. The pushing method is simple and the pushing structure occupies a small volume, which is suitable for miniaturizing the entire focusing and anti-shake structure 100. On the other hand, the carrier 10 is subjected to an elastic force to be reset to the initial state along the Z-axis direction, which effectively ensures the stability of the focusing process; on the other hand, the carrier 10 and the first frame 31 are suspended together in the second frame 41, and the carrier 10 is subjected to an elastic force to be reset to the initial state along the X-axis direction and the Y-axis direction, which ensures that the carrier 10 can effectively offset the jitter through the suspension mechanism 50; on the other hand, magnetic induction is used to push the carrier 10 to move along the X-axis direction and the Y-axis direction, and the directional jitter correction of the carrier 10 in the XY plane is realized by the magnetic induction pushing method, thereby further improving the focusing and anti-shake performance of the anti-shake structure 100.

[0047] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
