[0003] In order to solve the above technical problems, there are various micro anti-shake gimbals that use voice coil motors as driving devices in the relevant technologies. However, the magnetic field force of the rotating module driven by the voice coil motor attenuates significantly during operation, and is not suitable for large-angle rotation adjustment, which limits the anti-shake effect. There are also micro anti-shake gimbals that use SMA wires as driving devices. Although this type of micro anti-shake gimbal will not have obvious driving force attenuation problems, this type of anti-shake gimbal lacks smoothness during movement, which in turn affects the optical anti-shake performance.

[0053] The optical image stabilization adjustment module according to an embodiment of the present invention includes:

[0054] A first frame plate 21;

[0055] The bearing plate 11 is arranged inside the first frame plate 21. The bearing plate 11 and the first frame plate 21 are movably connected through two sets of first adapter structures. The first adapter structure includes a first connection ball 51a and a first rotating connection part 521. The first connection ball 51a is arranged in the first rotating connection part 521 and can rotate in the first rotating connection part 521. One of the bearing plate 11 and the first frame plate 21 is fixedly connected to the first connection ball 51a, and the other is fixedly connected to the first rotating connection part 521. The connecting line between the first adapter structures constitutes a first rotation axis.

[0056] The first actuator assembly 12 includes a first connecting plate 121, a second connecting plate 122 and a first SMA wire 123. The first connecting plate 121 is arranged at a rotation connection on the carrier plate 11. There are two second connecting plates 122, which are arranged on the first frame plate 21 and located on both sides of the first connecting plate 121. The second connecting plates 122 are connected to the first connecting plates 122 through the first SMA wire 123. The first actuator assembly 12 is used to drive the carrier plate 11 to rotate around the first rotation axis.

[0057] refer to Figure 1 The bearing plate 11 can be a rectangle or any other symmetrical shape; the first frame plate 21 can be a rectangle or any other symmetrical frame shape. The bearing plate 11 and the first frame plate 21 are movably connected through a pair of first adapter structures, and the connecting line between the first adapter structures constitutes a first rotation axis.

By providing the first connecting ball 51a, the rotational resistance of the supporting plate 11 when it rotates relative to the first frame plate 21 can be reduced, so that the supporting plate 11 can rotate more smoothly; by providing the first rotating connecting portion 521 and disposing the first connecting ball 51a in the first rotating connecting portion 521, the supporting plate 11 can be provided with sufficient supporting force to ensure the stability of the supporting plate 11 when it rotates; in addition, by providing the first rotating connecting portion 521, it can also ensure that the rotation angle of the supporting plate 11 relative to the first frame plate 21 is controlled within a certain range, and it can also prevent the SMA wire from being torn or colliding with other components due to excessive flipping angle caused by external force.

[0058] The first connecting plate 121 is arranged at the rotating connection of the supporting plate 11, and the second connecting plate 122 is arranged on the first frame plate 21 and is located on both sides of the first connecting plate 121. The two second connecting plates 122 are connected to the first connecting plate 121 through the first SMA wire 123. When in use, an electrical signal is applied to the first connecting plate 121 and one of the second connecting plates 122, so that the first SMA wire 123 is energized and contracted to generate a torque, thereby pulling the supporting plate 11 to rotate relative to the first frame plate 21.

[0059] The first actuator assembly 12 can be provided in multiple numbers, and its arrangement method can also be various. The first arrangement method is, for example, Figure 3 As shown, the first actuator assembly 12 is provided with two first connecting plates 121, which are symmetrically arranged on the upper surface and the lower surface of the carrier plate 11 and are both located on one side of the carrier plate 11, and the second connecting plate 122 is correspondingly arranged on the upper surface and the lower surface of the first frame plate 21. The second arrangement is as follows Figure 4 As shown, there are four first actuator assemblies 12, each in a group of two; in one group of first actuator assemblies 12, the first connecting plates 121 are symmetrically arranged at two rotating connections on the upper surface of the supporting plate 11, and the second connecting plates 122 are symmetrically arranged at corresponding positions of the first frame plate 21; another group of first actuator assemblies 12 are symmetrically arranged on the lower surfaces of the supporting plate 11 and the first frame plate 21.

[0060] The operation process of the first actuator assembly 12 is taken as an example of the first setting mode. Figure 6 When the supporting plate 11 needs to be rotated relative to the first frame plate 21, the first SMA wire 123 can be energized through the first connecting plate 121 and the second connecting plate 122 at both ends of a first SMA wire 123; for example, in order to flip the supporting plate 11 clockwise relative to the first frame plate 21, the staggered segments 123a and 123c of several first SMA wires 123 can be energized at the same time; in order to flip the supporting plate 11 counterclockwise relative to the first frame plate 21, the staggered segments 123b and 123d of several first SMA wires 123 can be energized at the same time.

[0061] In some specific embodiments of the present invention, a second frame plate 3 and a second actuator assembly 22 are also included; the first frame plate 21 is arranged inside the frame of the second frame plate 3, and the second frame plate 3 and the first frame plate 21 are movably connected through two sets of second adapter structures, and the second adapter structures include a second connecting ball 51b and a second rotating connecting part 522, and the second connecting ball 51b is arranged in the second rotating connecting part 522 and can rotate in the second rotating connecting part 522; one of the first frame plate 21 and the second frame plate 3 is fixedly connected to the second connecting ball 51b, and the other is fixedly connected to the second rotating connecting part 522; the connecting line between the second adapter structures constitutes a second rotation axis; the second rotation axis is perpendicular to the first rotation axis; the second actuator assembly 22 connects the first frame plate 21 and the second frame plate 3, and is used to drive the first frame plate 21 to rotate around the second rotation axis.

[0062] refer to Figure 1 and Figure 2 , a second frame plate 3 and a second actuator assembly 22 are provided, the first frame plate 21 is provided inside the frame of the second frame plate 3, the second frame plate 3 and the first frame plate 21 are movably connected through a second adapter structure, the connection line between the second connection ball 51b assembly constitutes a second rotation axis; the second rotation axis and the first rotation axis are perpendicular to each other; the second actuator assembly 22 can drive the first frame plate 21 to rotate relative to the second frame plate 3, and the second actuator assembly 22 can drive the first frame plate 21 to rotate relative to the second frame plate 3, thereby realizing dual-axis anti-shake. The second adapter structure includes a second connection ball 51b and a second rotation connection part 522, the second connection ball 51b is provided in the second rotation connection part 522 and can rotate in the second rotation connection part 522. By setting the second connecting ball 51b, the rotational resistance of the first frame plate 21 when rotating relative to the second frame plate 3 can be reduced, so that the first frame plate 21 can rotate more smoothly; by setting the second rotating connecting part 522, and setting the second connecting ball 51b in the second rotating connecting part 522, the second frame plate 3 can have sufficient supporting force on the first frame plate 21, thereby ensuring the stability of the first frame plate 21 during rotation.

[0063] In some specific embodiments of the present invention, the second actuator assembly 22 includes a third connecting plate 221, a fourth connecting plate 222 and a second SMA wire 223. The third connecting plate 221 is arranged at a rotating connection on the first frame plate 21. There are two fourth connecting plates 222, which are arranged on the second frame plate 3 and located on both sides of the third connecting plate 221. The fourth connecting plates 222 are connected to the third connecting plate 221 through the second SMA wire 223. The second actuator assembly 22 drives the first frame plate 21 to rotate relative to the second frame plate 3 around the second rotation axis.

[0064] The second actuator assembly 22 can be provided in multiple ways, and there are also multiple ways to provide it. The first way to provide it is, for example, Figure 3As shown, the second actuator assembly 22 is provided with two, the third connecting plate 221 is symmetrically arranged on the upper surface and the lower surface of the first frame plate 21, and both are located on one side of the first frame plate 21, and the fourth connecting plate 222 is correspondingly arranged on the upper surface and the lower surface of the second frame plate 3. The second setting method is as follows Figure 4 As shown, there are four second actuator assemblies 22, each in a group of two; the third connecting plate 221 in one group of second actuator assemblies 22 is symmetrically arranged at the rotation connection on the upper surface of the first frame plate 21, and the fourth connecting plate 222 is symmetrically arranged at the corresponding position of the second frame plate 3; the other group of second actuator assemblies 22 is symmetrically arranged on the upper and lower surfaces of the first frame plate 21 and the second frame plate 3.

[0065] Taking the first configuration as an example, the operation process of the second actuator assembly 22 is substantially the same as that of the first actuator assembly. Figure 5 When the first frame plate 21 needs to be rotated relative to the second frame plate 3, the second SMA wire 223 can be energized through the third connecting plate 221 and the fourth connecting plate 222 at both ends of a second SMA wire 223; for example, in order to flip the first frame plate 21 clockwise relative to the second frame plate 3, the staggered segments 223a and 223c of several second SMA wires 223 can be energized at the same time; in order to flip the first frame plate 21 counterclockwise relative to the second frame plate 3, the staggered segments 223b and 223d of several second SMA wires 223 can be energized at the same time.

[0066] By such a configuration, the contraction length of the SMA wire can be precisely controlled to achieve precise control of the rotation angle of the carrier plate 11 relative to the first frame plate 21 , while also ensuring a continuous large driving force without generating a magnetic field force.

[0067] In some specific embodiments of the present invention, the surfaces of the first connection ball 51a and the second connection ball 51b are coated with a wear-resistant layer. Coating the first connection ball 51a and the second connection ball 51b with a wear-resistant layer can reduce friction during rotation and increase the service life of the connection ball.

[0068] In some specific embodiments of the present invention, the first rotating connection part 521 and the second rotating connection part 522 include an upper transition part 52a and a lower transition part 52c, both of which are provided with transition grooves, and the first connecting ball 51a and the second connecting ball 51b are arranged in the transition grooves.

[0069] refer to Figure 7The distance between the bottom of the transition groove of the upper transition part 52a and the lower transition part 52c is equal to the diameter of the first connecting ball 51a and the second connecting ball 51b, which can limit the movement of the first connecting ball 51a and the second connecting ball 51b in the vertical direction; a certain gap is left between the side wall of the transition groove and the spherical surface of the first connecting ball 51a and the second connecting ball 51b, ensuring that the first connecting ball 51a and the second connecting ball 51b can move slightly left and right, reducing the friction between the first connecting ball 51a and the second connecting ball 51b and the transition groove when they rotate, and preventing the first connecting ball 51a and the second connecting ball 51b from being stuck between the transition groove and unable to move.

[0070] In some specific embodiments of the present invention, the supporting plate 11, the first frame plate 21 and the second frame plate 3 are all composite plates, the composite plates include an upper plate a, a middle plate b and a lower plate c, the upper transition portion 52a is arranged on the upper plate a, the first connecting ball 51a and the second connecting ball 51b are arranged on the middle plate b, and the lower transition portion 52c is arranged on the lower plate c.

[0071] refer to Fig. 9 The bearing plate 11, the first frame plate 21 and the second frame plate 3 are all composite plate structures, and the composite plate structure includes an upper plate a, a middle plate b and a lower plate c, that is, the bearing plate 11 includes a first upper plate a1, a first middle plate b1 and a first lower plate c1; the first frame plate 21 includes a second upper plate a2, a second middle plate b2 and a second lower plate c2; the second frame plate 3 includes a third upper plate a3, a third middle plate b3 and a third lower plate c3. The bearing plate 11, the first frame plate 21 and the second frame plate 3 are set as composite plates to increase the structural strength and reduce the difficulty of assembly. Before assembly, it is only necessary to bond the upper plate a, the middle plate b and the lower plate c together after they are processed separately, so that the assembly efficiency is greatly improved and the assembly cost is reduced.

[0072] In some specific embodiments of the present invention, in a composite plate provided with a rotating connection portion, a semicircular groove 52b is provided on the middle layer plate b, and the semicircular groove is located between the upper transition portion 52a and the lower transition portion 52c. The center of the semicircular groove 52b coincides with the center of the connecting ball, and the radius of the semicircular groove 52b is greater than the radius of the connecting ball.

[0073] refer to Figure 8 and Fig. 9 The semicircular groove allows the connecting ball to move slightly left and right, while limiting the left and right movement of the connecting ball within a certain range, to prevent the SMA wire from being torn due to a large movement of the connecting ball under external force impact.

[0074] In some specific embodiments of the present invention, the upper plates a of the carrier plate 11, the first frame plate 21, and the second frame plate 3 are all formed by one-time stamping and cutting of metal materials. Such a configuration can avoid the problem of plate deformation after the camera module 6 or other components are installed, which may cause the first connecting ball 51a and the second connecting ball 51b to rotate unsmoothly; in addition, the first upper plate a1, the second upper plate a2, and the third upper plate a3 are formed by stamping and cutting a whole piece of metal plate, and the first lower plate c1, the second lower plate c2, and the third lower plate c3 are also formed by stamping and cutting a whole piece of metal plate. Reference Fig. 9 The upper transition part 52a on the first frame plate 21 is formed by stamping and cutting the second upper plate a2, and the lower transition part 52c is formed by stamping and cutting the second lower plate c2. The upper transition part 52a on the second frame plate 3 is formed by stamping and cutting the third upper plate a3, and the lower transition part 52c is formed by stamping and cutting the third lower plate c3. The one-time stamping and cutting can ensure assembly accuracy and ensure smooth movement between the carrier plate 11, the first frame plate 21, and the second frame plate 3.

[0075] In some specific embodiments of the present invention, the surfaces of the upper plate a and the lower plate c are coated with insulating materials. Since the upper plate a and the lower plate c are formed by one-time stamping and cutting of metal materials, in order to make the SMA wire contract and generate torque when it is energized, circuits need to be set on the upper plate a and the lower plate c. In order to avoid short circuits in the circuits on the upper plate a and the lower plate c, the surfaces of the upper plate a and the lower plate c need to be coated with insulating materials to ensure circuit safety.

[0076] The following describes a camera according to a second embodiment of the present invention, which includes an optical image stabilization adjustment module and a lens module according to the first embodiment.

[0077] refer to Fig.10 The lens module 6 is arranged on the carrier plate 11. When the carrier plate 11 rotates relative to the first frame plate 21, the lens module 6 rotates accordingly to achieve an anti-shake effect. By using the SMA wire as a driving element, the contraction length of the SMA wire can be accurately controlled to achieve accurate control of the rotation angle of the lens module 6. At the same time, it can also ensure a continuous large driving force without generating a magnetic field force, which is beneficial to improving the optical anti-shake performance of the camera. In addition, since the first adapter structure and the second adapter structure use the structure of the first connecting ball 51a and the second connecting ball 51b, the anti-shake process of adjusting the rotation of the lens module 6 can be smoother and more stable.

[0078] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
