[0039] The anti-shake module can offset or compensate for camera shake by using specific hardware or software mechanisms, reduce image blur caused by shaking of electronic devices or cameras or instability when held in hand, and thus provide a more stable and clear image. Optical Image Stabilization (OIS) is achieved by adding movable optical elements inside the lens itself or on the lens module. When the camera shakes, these elements will be fine-tuned based on sensor signals or feedback from accelerometers to offset the impact of camera shake on the image. However, the anti-shake modules in related technologies are usually fragmented and complex in structure, with high structural and assembly costs, making it difficult to directly adapt to different types of cameras and application scenarios.

[0040] The present disclosure provides an anti-shake module. Figure 1 is a schematic diagram of a three-dimensional structure of a camera in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of the exploded structure of a camera in an exemplary embodiment of the present disclosure, such as Figure 1 , Figure 2 As shown, the anti-shake module 1 includes a mounting structure 11, an electrically controlled deformable member 13 and an elastic structure 12. The electrically controlled deformable member 13 includes a first connection end 131 and a second connection end 132, and the first connection end 131 is fixed to the mounting structure 11. The elastic structure 12 includes a connection portion 121 and a deformable portion 122, and the connection portion 121 is fixedly connected to the mounting structure 11, and the deformable portion 122 is connected to the second connection end 132, so that the push end 1221 of the deformable portion 122 generates a driving displacement along the deformation of the electrically controlled deformable member 13 along the preset deformation direction.

[0041] The anti-shake module 1 drives the push end 1221 of the deformation part 122 of the elastic structure 12 to generate a driving displacement through the deformation of the electrically controlled deformable member 13 along a preset deformation direction, thereby obtaining an anti-shake effect. The elastic structure 12 and the electrically controlled deformable member 13 are assembled to the mounting structure 11 to form an integrated anti-shake module 1, which improves the assembly convenience and adaptability of the anti-shake module 1 in different application scenarios.

[0042] It should be noted that the electrically-controlled deformable member 13 can be deformed by electrical control, so as to control deformation parameters such as deformation direction and deformation size. For example, the electrically-controlled deformable member 13 can produce a desired deformation by electrically-controlled heating.

[0043] In some embodiments, Figure 3 As shown, the electrically controlled deformable member 13 includes a linear structure, and a first connection end 131 and a second connection end 132 are located at two ends of the electrically controlled deformable member 13. The linear structure has the advantages of small radial size, low cost and convenient telescopic control, so that better deformation accuracy can be obtained during the electrically controlled deformation process.

[0044] In other embodiments, the electrically-controlled deformable member 13 may also include a sheet structure, a block structure, etc., which can also achieve the effect of electrically-controlled deformation. Alternatively, the electrically-controlled deformable member 13 may also be a combination of at least two of a linear structure, a sheet structure, a block structure, or other irregular shapes to adapt to different deformation requirements, structural strength requirements, and assembly requirements.

[0045] In the above embodiment, the material of the electrically controlled deformable member 13 may include memory alloy to obtain the expected deformation and recovery requirements. Alternatively, the material of the electrically controlled deformable member 13 may also be other electro-deformable materials, which is not limited in the present disclosure.

[0046] In some embodiments, the deformation portion 122 includes a spring sheet connected to the connection portion 121, so as to obtain driving displacement through the structural form of the spring sheet, which helps to simplify the structure of the deformation portion 122 and improve the reliability of deformation.

[0047] The push end 1221 includes a protruding structure disposed on the spring sheet and protruding toward the side opposite to the mounting structure 11. The protruding structure can move in a preset direction when the spring sheet is deformed, thereby generating a push effect. The protruding structure can ensure the strength of the push structure, and can also prevent other structures of the spring sheet except the protruding structure from interfering with the anti-shake module 1 or other modules of the camera 2 during the deformation process.

[0048] The protruding structure may include an arc-shaped abutting surface, so that the arc-shaped abutting surface can accommodate the directional deviation of the driving displacement and improve the abutment reliability.

[0049] In the above embodiment, the deformation part 122 may include a connecting body 1222 and at least two spring sheets, one side of the connecting body 1222 is connected to the connecting part 121, and the spring sheets are distributed at intervals on the other side of the connecting body 1222. The stability and reliability of the deformation part 122 when it abuts against the focusing module 23 can be increased by at least two spaced-apart spring sheets.

[0050] The working process of the anti-shake module 1 may be: when the electrically controlled deformable member is controlled to heat up, the electrically controlled deformable member 13 contracts to pull the deformable portion 122 to move in the contraction direction, and the protruding structure on the spring sheet as the abutment end generates a driving displacement perpendicular to the contraction direction due to the contraction of the deformable portion 122. The above-mentioned driving displacement can be used to drive the focus module 23 to move along the action direction of the driving displacement, thereby obtaining a corresponding anti-shake effect.

[0051] In some embodiments, the side of the connecting body 1222 connected to the connecting portion 121 is further provided with an extension structure 1223 protruding away from the elastic sheet, and the second connecting end 132 is fixedly connected to the extension structure 1223. By connecting the extension structure 1223 to the second connecting end 132, not only can the structural interference between the extension structure 1223 and the elastic sheet be avoided, but also the flexibility of the connection method between the second connecting end 132 and the connecting body 1222 can be improved.

[0052] For example, the first connection end 131 of the electrically-controlled deformable member 13 can be fixed to the mounting structure 11 by welding, clamping, etc., and the second connection end 132 can also be fixed to the mounting structure 11 by welding, clamping, etc.

[0053] In other embodiments, the elastic structure 12 may also be other structures with stress-bearing deformation properties, such as springs, rubber parts, and structural parts including springs or rubber structures. The present disclosure does not limit the specific structural form of the elastic structure 12.

[0054] In some embodiments, the anti-shake module 1 includes at least one mounting structure 11, each mounting structure 11 is provided with at least two elastic structures 12, and the preset deformation directions of at least two electrically-controlled deformable parts 13 connected to different elastic structures 12 are parallel, so that different elastic structures 12 can be driven by different electrically-controlled deformable parts 13 to deform in a preset deformation direction, thereby ensuring that the force for generating the driving displacement is sufficient and improving the accuracy and reliability of the driving displacement.

[0055] On the mounting surface 111 of the mounting structure 11, the deformation portion 122 of at least one elastic structure 12 may be close to the first end 1111 of the mounting surface 111, and the deformation portion 122 of at least one elastic structure 12 may be close to the second end 1112 of the mounting surface 111. The first end 1111 and the second end 1112 are arranged opposite to each other. Distributing the deformation portions 122 of the two elastic structures 12 at opposite ends of the mounting structure 11 helps to improve driving stability.

[0056] In the above embodiment, at least two mounting structures 11 may be provided for the anti-shake module 1, and the mounting surfaces 111 of at least two mounting structures 11 are relatively vertical, so that the deformation part 122 is driven to be displaced in two directions perpendicular to each other due to the pulling of the electrically controlled deformable member 13, thereby achieving an anti-shake effect. For example, two groups of mounting structures 11 may be provided for the anti-shake module 1, and the mounting surfaces 111 of each group of mounting structures 11 are parallel and the push ends 1221 on one group of mounting structures 11 are respectively in contact with the opposite side surfaces of the focus module 23, so as to obtain a bidirectional drive displacement in the push direction.

[0057] In other embodiments, the anti-shake module 1 includes at least one mounting structure 11, each mounting structure 11 is provided with at least two elastic structures 12, and at least two electrically-controlled deformable members 13 can be connected to the same elastic structure 12, and the preset deformation directions of the electrically-controlled deformable members 13 connected to the same elastic structure 12 can be the same or different. When the preset deformation directions of the electrically-controlled deformable members 13 connected to the same elastic structure 12 are the same, the deformation force of the electrically-controlled deformable members 13 can be increased, thereby improving the driving reliability. When the preset deformation directions of the electrically-controlled deformable members 13 connected to the same elastic structure 12 are different, the displacement can be obtained in different preset deformation directions by controlling different electrically-controlled deformable members 13, thereby increasing the anti-shake direction of a single mounting structure 11.

[0058] In some embodiments, the anti-shake module 1 may include at least two mounting structures 11, and the mounting postures of at least two mounting structures 11 are different, so that the driving displacement direction of at least one deformation part 122 on at least one mounting structure 11 is different from that of at least one deformation part 122 on another mounting structure 11, so that the deformation part 122 obtains driving displacement in two directions due to the pulling of the electrically-controlled deformable part 13, thereby achieving an anti-shake effect.

[0059] Optionally, at least one pair of mounting structures 11 are arranged opposite to each other, and the driving displacement directions of the deformation parts 122 on the pair of mounting structures 11 arranged opposite to each other are opposite. For example, two groups of mounting structures 11 can be provided for the anti-shake module 1, the mounting surfaces 111 of each group of mounting structures 11 are parallel, and the pushing ends 1221 on one group of mounting structures 11 are respectively in contact with the opposite side surfaces of the focus module 23, so as to obtain a bidirectional driving displacement in the pushing direction.

[0060] It should be noted that the mounting structure 11 may be a plate-like structure, so as to facilitate the installation and fixation of the elastic structure 12 and the electrically-controlled deformable member 13 , and facilitate assembly after the anti-shake module 1 is formed into a module.

[0061] The present disclosure further provides a camera 2, such as Figure 1 As shown, the camera 2 includes a focus module 23 and the anti-shake module 1 , and the push end 1221 abuts against the focus module 23 .

[0062] Since the anti-shake module 1 drives the push end 1221 of the deformation part 122 of the elastic structure 12 to generate a driving displacement through the deformation of the electrically controlled deformable member 13 along the preset deformation direction, an anti-shake effect is obtained. The elastic structure 12 and the electrically controlled deformable member 13 are assembled to the mounting structure 11 to form an integrated anti-shake module 1, which improves the assembly convenience and adaptability of the anti-shake module 1 in different application scenarios.

[0063] Furthermore, if Figure 1 , Figure 2As shown, the camera 2 may further include a first elastic connection component 22 and a housing 21, and the housing 21 forms a storage space. The focus module 23 and the anti-shake module 1 are located in the storage space, and the mounting structure 11 is fixedly assembled to the housing 21. The first elastic connection component 22 connects the housing 21 and the focus module 23, so that the focus module 23 can be pulled by the first elastic connection component 22 to form an anti-shake movement based on the driving displacement when the push end 1221 of the deformation part 122 abuts.

[0064] Among them, the shell 21 may include a base 212 and an upper shell 211 assembled on the base 212. The first elastic connecting component 22 and the mounting structure 11 are respectively fixedly connected to the base 212, dividing the shell 21 into the base 212 and the upper shell 211, thereby improving the assembly convenience of the first elastic connecting component 22 and the anti-shake module 1 and the focus module 23.

[0065] In the above embodiment, if Figure 4 , Figure 5 As shown, the focus module 23 may include a fixed component 231, a movable component 233, and a second elastic connection component 232 connecting the fixed component 231 and the movable component 233, and the push end 1221 abuts against the fixed component 231. During the operation of the camera 2, the movable component 233 inside the focus module 23 may move relative to the fixed component 231 to achieve the focus function, and the outer side surface 2311 of the fixed component 231 may move under the push and pull action of the push end 1221 to achieve the anti-shake function.

[0066] Furthermore, the focus module 23 may also include a position monitoring component, the first part of which is assembled on the moving subassembly 233, and the second part of which is assembled on the fixed assembly 231, so as to obtain the focusing accuracy of the moving subassembly 233 and the anti-shake accuracy of the fixed assembly 231 through the parameters of the first part and the second part. The position monitoring component may be a capacitive detection component or a Hall detection component.

[0067] The present disclosure provides an electronic device, which includes the anti-shake module 1 or the camera 2 .

[0068] Since the anti-shake module 1 drives the push end 1221 of the deformation part 122 of the elastic structure 12 to generate a driving displacement through the deformation of the electrically controlled deformable member 13 along the preset deformation direction, an anti-shake effect is obtained. The elastic structure 12 and the electrically controlled deformable member 13 are assembled to the mounting structure 11 to form an integrated anti-shake module 1, which improves the assembly convenience and adaptability of the anti-shake module 1 in different application scenarios.

[0069] It should be noted that the above-mentioned electronic device can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted terminal, a medical terminal, etc., and the present disclosure does not limit this.

[0070] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure.
