[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of a camera module provided by the embodiments of the present application is shown in Figure 2 A structural schematic diagram of a camera module provided by the embodiments of the present application is shown in Figure 1 The camera module 10 provided by the embodiments of the present application can be used to realize the functions of photographing, video recording, face recognition unlocking or code payment of an electronic device. In addition, it should be noted that the camera module 10 can be a front camera or a rear camera, and the embodiments are not limited in this regard. The structure of the camera module 10 will be described in detail below with reference to the drawings. The camera module 10 can include an anti-shake assembly 100, an image sensor assembly 200 and a lens 300.

[0036] The material of the lens 300 can be glass or plastic, etc. The lens 300 can be provided with multiple layers of lenses inside. The lens 300 can collect external light and change the propagation path of the light, and can focus the light. As shown in Figure 2 The camera module 10 can further include a filter assembly 500, which can be arranged between the lens 300 and the image sensor assembly 200 in the optical axis direction of the lens 300. The filter assembly 500 can include one or more layers of filters 510 and a filter support 520 carrying the filters 510. The multiple layers of filters 510 can correct and filter light from each other, so as to filter out stray light (such as infrared light) layer by layer when the light passes through the lens 300, thereby increasing the imaging effect of the camera module 10. Exemplarily, the filter 510 can be blue glass or other filter structure, which can be fixed on the filter support 520 by means of dispensing and baking, etc.

[0037] The image sensor assembly 200 can be disposed opposite the lens 300 in the optical axis direction of the lens 300, and the image sensor assembly 200 can include an image sensor 210 and an image sensor circuit board 220. The lens 300, the image sensor 210, and the image sensor circuit board 220 can be stacked in a first direction H1, which can be a thickness direction of the camera module 10 or an optical axis direction of the lens 300. The lens 300 and the image sensor 210 can be parallel to each other. The image sensor 210 can be, but is not limited to, a Charge Coupled Device (CCD), a Complementary Metal Oxide Semiconductor (CMOS), or the like. The image sensor 210 is mainly used to receive light collected by the lens 300 and convert the light signal into an electrical signal to achieve the imaging requirement of the camera module 10. The image sensor circuit board 220 can carry and electrically connect the image sensor 210 to provide power and control signals for the image sensor 210. The image sensor 210 and other components can be mounted on the image sensor circuit board 220 by surface mounting technology (SMT), die bonding (D / B), wire bonding (W / B), or the like.

[0038] The anti-shake assembly 100 can be disposed on a side of the image sensor 210 away from the lens 300 in the optical axis direction of the lens 300. The anti-shake assembly 100 can be connected to the image sensor 210 to drive the image sensor 210 to move. The anti-shake assembly 100 can be used to improve the imaging effect of the camera module 10 caused by user shaking during use, so that the imaging effect of the image sensor 210 can meet the user's use requirement. The anti-shake assembly 100 can provide driving force to drive the image sensor 210 to move.

[0039] Based on the optical anti-shake technology, a gyroscope or an accelerometer or the like sensor in the camera module 10 or in the same electronic device as the camera module 10 can detect the shaking of the lens 300 to generate a shaking signal, and transmit the shaking signal to a processing chip of the electronic device and / or the camera module 10. The processing chip of the electronic device and / or the camera module 10 can calculate the displacement amount that needs to be compensated by the anti-shake assembly 100, so that the anti-shake assembly 100 can compensate for the lens 300 according to the shaking direction and displacement amount of the lens 300, thereby improving the imaging effect of the camera module 10 caused by user shaking during use.

[0040] In this regard, please refer to Figure 2Please refer to Figure 3 、 Figure 4 and Figure 5 , Figure 3 is an exploded structural schematic view of the anti-shake assembly shown in Figure 2 , Figure 4 is a structural schematic view of the anti-shake assembly from another perspective shown in Figure 2 , Figure 5 is a partial structural schematic view of the anti-shake assembly shown in Figure 4 .

[0041] The anti-shake assembly 100 can include a carrier plate 110, a driving mechanism 120, and a bottom plate 130.

[0042] The bottom plate 130 can serve as a carrier of the anti-shake assembly 100, and the carrier plate 110 and the driving mechanism 120 are both directly or indirectly arranged on the bottom plate 130.

[0043] The carrier plate 110 can serve as a circuit board of the image sensor 210 and carry the image sensor 210, i.e., the carrier plate 110 is an image sensor circuit board 220, and the carrier plate 110 can also serve as a carrier of the circuit board of the image sensor 210, i.e., the image sensor circuit board 220 and the image sensor 210 are arranged on the carrier plate.

[0044] The carrier plate 110 can include a movable part 111 and a fixed part 112 arranged at intervals, the fixed part 112 of the carrier plate 110 can be connected to and fixed with the bottom plate 130, and the movable part 111 can carry the image sensor 210 (or the image sensor assembly 200), which can be directly or indirectly connected to the movable part 111. The fixed part 112 can be sleeved on the outer periphery of the movable part 111, and a gap can be formed between the fixed part 112 and the movable part 111 to allow the movable part 111 to move relative to the fixed part 112. The image sensor 210 (or the image sensor assembly 200) can be directly or indirectly connected to the movable part 111 and move synchronously with the movable part 111.

[0045] The carrier plate 110 can be arranged opposite to the driving mechanism 120 in the direction of the optical axis of the lens 300. The driving mechanism 120 can be arranged on one side of the carrier plate 110. For example, as shown in Figure 3As shown, the driving mechanism 120 can be disposed on the side of the bearing plate 110 away from the bottom plate 130, so that the driving mechanism 120 can drive the bearing plate 110 to move above the bearing plate 110. Of course, the driving mechanism 120 can also be disposed on the side below the bearing plate 110, for example, on the side below the bearing plate 110 and the image sensor assembly 200, so that the driving mechanism 120 can drive the bearing plate 110 to move below the bearing plate 110 and the image sensor assembly 200. The embodiments of the present application do not specifically limit the setting position of the driving mechanism 120.

[0046] The driving mechanism 120 can include a moving piece 121 and a plurality of deformation pieces 122. The moving piece 121 can be directly or indirectly connected with the movable piece 111, so that the moving piece 121, the movable piece 111 and the image sensor 210 (or the image sensor assembly 200) disposed on the movable piece 111 can form an integral whole. One end of each deformation piece 122 can be directly or indirectly connected with the fixed piece 112, and the other end can be directly or indirectly connected with the moving piece 121. The plurality of deformation pieces 122 can be deformed under the energized state to drive the integral whole formed by the moving piece 121, the movable piece 111 and the image sensor 210 to move, so that the moving piece 121, the movable piece 111 and the image sensor 210 can move synchronously. For example, the plurality of deformation pieces 122 can be deformed under the energized state to drive the moving piece 121, the movable piece 111 and the image sensor 210 to move along the direction perpendicular to the optical axis of the lens 300 or to rotate around the optical axis of the lens 300. The image sensor 210 can rotate in the X-axis, Y-axis or XOY plane under the action of the anti-shake assembly 100.

[0047] It can be understood that the optical axis direction of the lens 300 can be a first direction H1, which can be a vertical direction, for example, the Z-axis direction in the coordinate axis. The direction perpendicular to the optical axis of the lens 300 can be a second direction, which can be any horizontal direction in the horizontal plane, for example, the X-axis direction or the Y-axis direction in the coordinate axis. Around the optical axis direction of the lens 300, it can be any direction in the plane perpendicular to the optical axis of the lens 300, for example, any direction in the XOY plane in the coordinate axis.

[0048] It can be understood that the plurality of deformation members 122 are made of shape memory alloys (SMA), which can be heated and deformed in an energized state, and the length of the plurality of deformation members 122 can change when deformed. When the plurality of deformation members 122 are energized or different sizes of current are transmitted to the plurality of deformation members 122, the length of the plurality of deformation members 122 can change. Since one end of each deformation member 122 is fixed with the fixed part 112 of the carrier plate 110 and the other end moves with the moving part 121, the plurality of deformation members 122 with changed length can drive the moving part 121 to move, and the moving part 121 can also drive the movable part 111 and the image sensor 210 directly or indirectly connected thereto to move.

[0049] In the anti-shake assembly 100, the driving mechanism 120 includes the moving part 121 and the plurality of deformation members 122. The moving part 121 is connected with the movable part 111 of the carrier plate 110. One end of each deformation member 122 is connected with the moving part 121, and the other end is connected with the fixed part 112 of the carrier plate 110. Thus, when the plurality of deformation members 122 are deformed, the moving part 121 can be driven to move, and the moving part 121 can drive the movable part 111 and the image sensor 210 disposed on the movable part 111 to move, so that the anti-shake assembly 100 can realize the anti-shake function of the image sensor 210. Meanwhile, the two ends of the deformation member 122 are connected with the fixed part 112 and the moving part 121 respectively, and the deformation member 122 does not need to occupy the space of the movable part 111, and the deformation member 122 will not affect the distribution of the circuit on the movable part 111, so that the influence of the deformation member 122 on the circuit on the movable part 111 can be reduced. Moreover, the moving part 121 and the carrier plate 110 are independent of each other, and the moving part 121 and the carrier plate 110 can be produced modularly in the production and assembly process, so that the adaptability of the moving part 121 and the carrier plate 110 can be improved. It should be noted that the moving part 121 and the carrier plate 110 can also be produced together by using the same production process. The specific preparation process of the moving part 121 and the carrier plate 110 is not limited in the present application.

[0050] The anti-shake assembly 100 includes an anti-shake housing 160, which can be disposed on and cover the fixed part 112. The anti-shake housing 160 can cover the driving mechanism 120 and the movable part 111, and the image sensor assembly 200 and the filter assembly 500 can also be disposed in the anti-shake housing 160. The anti-shake housing 160 has an opening in the middle, which is opposite to the lens 300, so that the light collected by the lens 300 can pass through the opening and reach the filter 510 and the image sensor 210.

[0051] Since the moving piece 121 is driven by the deformation piece 122, the deformation piece 122 can be deformed to drive the moving piece 121 to move in the state of being powered on, and the deformation piece 122 has the maximum plastic deformation in the state of not being powered on. When the anti-shake assembly 100 is subjected to external forces such as impact and collision, the moving piece 121 will be greatly offset, which is easy to hit the anti-shake shell 160 arranged around the moving piece 121, causing the moving piece 121 to be deformed. Since the power adjustment of the deformation piece 122 is very fine, the deformation of the moving piece 121 causes the deformation of the deformation piece 122 to be inconsistent with the actual compensation amount, affecting the anti-shake performance of the anti-shake assembly 100. In addition, when the offset amount of the moving piece 121 is too large and exceeds the maximum plastic deformation of the deformation piece 122 in the state of not being powered on, the deformation piece 122 will be damaged, affecting the anti-shake performance of the anti-shake assembly 100. In the case of extreme drop or impact force, the moving piece 121 hitting the anti-shake shell 160 will also produce material debris, which will enter the lens 300 or the image sensor 210, damaging the entire camera module 10.

[0052] Therefore, by improving the anti-shake assembly, a structure for limiting the movement range of the moving piece 121 is arranged to avoid the problems caused by the large offset of the moving piece 121 in the anti-shake assembly. Please refer to Figure 4 and Figure 5 , continue to refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , Figure 6 a structure diagram of a moving piece provided by an embodiment of the present application, Figure 7 a structure diagram of a limiting piece provided by an embodiment of the present application, Figure 8 a structure diagram of the moving piece and the limiting piece after assembly provided by an embodiment of the present application, Figure 9 a structure diagram of an anti-shake shell provided by an embodiment of the present application.

[0053] The anti-shake shell 160 is provided with a limiting groove 170, and the moving piece 121 is provided with a limiting piece 180. At least a part of the limiting piece 180 is located in the limiting groove 170, and the limiting piece 180 is arranged in the limiting groove 170. Since the moving piece 121 is provided with the limiting piece 180 located in the limiting groove 170, when the moving piece 121 is subjected to external force and offset, the groove wall of the limiting groove 170 of the anti-shake shell 160 can limit the unexpected offset of the moving piece 121, avoiding the defects caused by the unexpected offset. It can be understood that the expected offset of the moving piece 121 is the anti-shake compensation offset caused by the deformation of the deformation piece after being powered on, and the unexpected offset of the moving piece 121 is the unexpected offset caused by the collision, impact or other external forces other than the deformation of the deformation piece 122.

[0054] The distance between the groove wall of the limiting groove 170 and the limiting member 180 is greater than or equal to the maximum displacement of the plurality of deformation members 122 in the conductive state to cause the movement of the moving member 121, and is less than the maximum displacement of the moving member 121 in the non-conductive state. That is, the distance between the groove wall of the limiting groove 170 and the limiting member 180 can be set according to the maximum image sensor anti-shake compensation amount of the anti-shake assembly 100, the distance from the moving member 121 to the anti-shake housing 160, and the plastic deformation limit of the deformation member 122.

[0055] For example, the anti-shake housing 160 includes a main body part 101 and an edge part 102 arranged around the main body part 101, the edge part 102 is connected with the fixing member 112, the main body part 101 is provided with an opening 1011, the opening 1011 is opposite to the image sensor 210, and the limiting groove 170 is arranged on the main body part 101 and adjacent to the opening 1011.

[0056] The limiting groove 170 can be in communication with the opening 1011, the limiting member 180 can include a connecting part 181, a first protruding part 182 and a second protruding part 183, the connecting part 181 connects the first protruding part 182 and the second protruding part 183 and is arranged between the first protruding part 182 and the second protruding part 183, the connecting part 181 is connected with the moving member 121, at least a part of the first protruding part 182 and at least a part of the second protruding part 183 are located in the limiting groove 170 and are spaced apart from the groove wall of the limiting groove 170. The limiting groove 170 can be in the same plane as the opening 1011, and the two ends of the connecting part 181 protrude towards the limiting groove 170 to form the first protruding part 182 and the second protruding part 183. The distance from the first protruding part 182 to the first groove wall 171 of the limiting groove 170 is greater than or equal to the maximum distance of the conductive deformation of the deformation member 122 to drive the moving member 121 to move towards the first groove wall, and is less than the minimum distance from any part of the moving member 121 to the edge part 102 of the anti-shake housing 160 in the non-conductive state of the deformation member 122. The distance from the second protruding part 183 to the second groove wall 172 of the limiting groove 170 is greater than or equal to the maximum distance of the conductive deformation of the deformation member 122 to drive the moving member 121 to move towards the second groove wall 172, and is less than the minimum distance from any part of the moving member 121 to the edge part 102 of the anti-shake housing 160 in the non-conductive state of the deformation member 122. By setting the distance between the groove wall of the limiting groove 170 and the limiting member 180, when the moving member 121 is subjected to an unexpected deviation due to an external force, the limiting member 180 can be limited by the groove wall of the limiting groove 170, to avoid further unexpected deviation of the moving member 121, and to meet the needs of the moving member 121 driving the image sensor for anti-shake compensation.

[0057] The limiting member 180 can be arranged on the moving member 121 by welding, injection molding, clamping, bonding, screwing or the like. Of course, the limiting member 180 and the moving member 121 can be integrally formed.

[0058] In some embodiments, in order to avoid debris or noise when the limiting member 180 collides with the groove wall of the limiting groove 170, a buffer member can be arranged on the groove wall of the limiting groove 170 and / or the surface of the limiting member 180. The buffer member can be foam, silica gel, rubber, elastic glue or the like structure having a buffering effect. It can be understood that after the buffer member is added to the groove wall of the limiting groove 170, the spacing distance between the limiting member 180 and the limiting groove 170 needs to consider the thickness of the buffer member.

[0059] The structure of the limiting groove 170 and the limiting member 180 provided by the embodiments of the present application is only exemplary, and the structure of the limiting groove 170 and the limiting member 180 can also be designed according to actual needs or process requirements. Please continue to refer to Figure 10 , Figure 10 Another structure diagram of the anti-shake assembly provided by the embodiments of the present application. The limiting member 180 can be a cylindrical structure protruding towards the limiting groove 170. The groove wall of the limiting groove 170 can be designed according to the structure of the limiting member 180. The spacing between the groove wall of the limiting groove 170 and the limiting member 180 meets the above spacing requirements.

[0060] Please continue to refer to Figure 5 The driving mechanism 120 can also include a plurality of movable ends 123 and a plurality of fixed ends 124. The plurality of movable ends 123 can be arranged on the moving member 121, and the plurality of fixed ends 124 can be arranged on the fixed member 112. One end of the shape-changing member 122 can be directly or indirectly connected to one movable end 123, and the other end can be directly or indirectly connected to one fixed end 124. When the length of the shape-changing member 122 changes in the energized state, the movable end 123 connected to the shape-changing member 122 can move with the moving member 121 as the length of the shape-changing member 122 changes, and the fixed end 124 connected to the shape-changing member 122 is fixed with the fixed member 112 and does not move.

[0061] It can be understood that one or more movable ends 123 can be arranged at intervals and connected to the moving member 121, and two or more of the plurality of movable ends 123 can also be arranged adjacent to each other (or connected to each other) without intervals. Similarly, one or more fixed ends 124 can be arranged at intervals and connected to the fixed member 112 (for example, arranged at intervals on the front surface of the fixed member 112), and two or more of the plurality of fixed ends 124 can also be arranged adjacent to each other (or connected to each other) without intervals. The embodiments of the present application do not specifically set the arrangement mode of the plurality of movable ends 123 and the plurality of fixed ends 124.

[0062] Exemplarily, asFigure 5 As shown, the driving mechanism 120 can include two movably arranged ends 123 and two fixedly arranged ends 124. For example, the two movably arranged ends 123 and the two fixedly arranged ends 124 can form a quadrilateral structure, the two movably arranged ends 123 can be located on one diagonal line of the quadrilateral structure, the two fixedly arranged ends 124 can be located on another diagonal line of the quadrilateral structure, and the two movably arranged ends 123 and the two fixedly arranged ends 124 can form four vertices of the quadrilateral structure. At this time, the anti-shake assembly 100 can also correspondingly be provided with four deformation members 122, and the four deformation members 122 can be arranged corresponding to four sides of the quadrilateral structure. Based on the characteristic that the quadrilateral structure is easy to deform, when the deformation member 122 deforms, the deformation member 122 is more easily affected by the movably arranged end 123 and the fixedly arranged end 124 located at the vertex to change the quadrilateral structure, thereby more easily driving the movable element 111 and the image sensor 210 arranged on the movable element 111 to move.

[0063] It can be understood that one or more movably arranged ends 123 can be integrally formed on the moving element 121, and one or more fixedly arranged ends 124 can be integrally formed on the fixed element 112. When the deformation member 122 is connected to the movably arranged end 123 or the fixedly arranged end 124 by winding, clamping, welding or the like, compared with the scheme that the deformation member 122 is directly connected to the fixed element 112, the process of connecting the deformation member 122 to the movably arranged end 123 and the fixedly arranged end 124 in the embodiment of the application does not easily cause damage to the fixed element 112 and does not easily damage the circuit traces on the fixed element 112.

[0064] It can be understood that the number of the movably arranged ends 123 and the fixedly arranged ends 124 can be equal to half the number of the deformation members 122, so that one movably arranged end 123 can be connected to the end portions of two deformation members 122, and one fixedly arranged end 124 can also be connected to the end portions of two deformation members 122, thereby the driving mechanism 120 in the embodiment of the application can be provided with fewer movably arranged ends 123 and fixedly arranged ends 124.

[0065] It can be understood that the anti-shake assembly 100, the camera module 10 or the electronic device can also include a driving control chip, which can be arranged on the fixed element 112 of the carrier plate 110 and form a driving circuit for causing the deformation member 122 to deform. Alternatively, the driving circuit can also be separately arranged on the fixed element 112, and the driving control chip can be electrically connected to the driving circuit on the fixed element 112 through the driving adapter plate 700 described above. At least one of the plurality of movably arranged ends 123 and the plurality of fixedly arranged ends 124 can be a conductive device, so that the driving circuit can be electrically connected to the deformation member 122 through the plurality of movably arranged ends 123, or through the plurality of fixedly arranged ends 124, or through the plurality of movably arranged ends 123 and the plurality of fixedly arranged ends 124 at the same time, thereby the driving control chip can provide a driving current for the deformation member 122.

[0066] It can be understood that the movable end 123 and the fixed end 124 can have a certain height, so that the movable end 123 and the fixed end 124 can isolate the bearing plate 110 from the moving part 121 and the deformation part 122. Thus, the deformation parts 122 are not easy to contact the bearing plate 110 when deforming, and the deformation of the deformation part 122 can be avoided by the bearing plate 110. At the same time, the circuit on the bearing plate 110 can be prevented from being short-circuited by contacting the deformation part 122.

[0067] Optionally, the driving mechanism 120 can further include a heightening part 150, which is arranged between the moving part 121 and the movable part 111. The heightening part 150 can elevate the moving part 121, so that the movable end 123 connected with the moving part 121 is also elevated, and the moving part 121 and the fixed part 112 are spaced apart.

[0068] The anti-shake assembly 100 can be provided with a plurality of movable ends 123 and fixed ends 124. The deformation part 122 is connected with the fixed part 112 of the bearing plate 110 and the moving part 121 of the driving mechanism 120 through the movable end 123 and the fixed end 124. The connection process of the deformation part 122 is simpler and will not affect the circuit layout on the fixed part 112. At the same time, the movable end 123 and the fixed end 124 can be used as conductive devices to supply power to the deformation part 122, which can simplify the power supply circuit layout of the deformation part 122 and realize the miniaturization design of the anti-shake assembly 100.

[0069] The plurality of deformation parts 122 can be arranged around the moving part 121, so that the deformation part 122 can better control the movement of the moving part 121. Please continue to refer to Figure 7 The moving part 121 can include an intermediate part 1215, a first extension part 1217 and a second extension part 1218. The intermediate part 1215 can be a rectangular frame structure. The first extension part 1217 and the second extension part 1218 are arranged at two opposite corners of the intermediate part 1215. The intermediate part 1215 is located above the movable part 111. The first extension part 1217 extends from one corner of the intermediate part 1215 to above the fixed part 112, and the second extension part 1218 extends from another corner of the intermediate part 1215 to above the fixed part 112. The first extension part 1217 and the second extension part 1218 can extend in directions away from each other. One movable end 123 is arranged on each of the first extension part 1217 and the second extension part 1218. The first extension part 1217 and / or the second extension part 1218 can be provided with a limiting part 180.

[0070] The fixed part 112 can be a rectangular frame structure, and the movable part 111 can be located in the hollow area of the fixed part 112. When the driving mechanism 120 includes two movable ends 123 and two fixed ends 124, the two movable ends 123 can be arranged on the first extension 1217 and the second extension 1218 of the moving part 121, and the two fixed ends 124 can be arranged on the opposite two ends of the fixed part 112, each movable end 123 is located between the two fixed ends 124, and each fixed end 124 is located between the two movable ends 123. Therefore, the two movable ends 123 can be located on the diagonal line of the moving part 121, and the two fixed ends 124 can be located on the diagonal line of the moving part 121.

[0071] The anti-shake assembly 100 includes four deformation parts 122, which are located on the four sides of the fixed part 112. Specifically, each deformation part 122 is arranged opposite to one side of the fixed part 112, and one end of each deformation part 122 is connected with a movable end 123 and the other end is connected with a fixed end 124. It can be understood that the four deformation parts 122 can cooperate to move the moving part 121, for example, to move the moving part 121 in a direction perpendicular to the optical axis of the lens 300 or to rotate the moving part 121 around the optical axis of the lens 300.

[0072] In order to facilitate the understanding of the movement of the image sensor 210 controlled by the deformation part 122 in this embodiment, the following examples are given. Please refer to Figure 10 , continue to refer to Figure 11 , Figure 11 Figure 10 The four deformation parts 122 can include a first deformation part 1221, a second deformation part 1222, a third deformation part 1223, and a fourth deformation part 1224.

[0073] If the first deformation part 1221 is energized to be shortened and contracted, and / or the third deformation part 1223 is energized to be lengthened and relaxed, the first deformation part 1221 and the third deformation part 1223 can drive the moving part 121, the movable part 111 and the image sensor 210 to move rightward along the X-axis direction. If the first deformation part 1221 is energized to be lengthened and relaxed, and / or the third deformation part 1223 is energized to be shortened and contracted, the first deformation part 1221 and the third deformation part 1223 can drive the moving part 121, the movable part 111 and the image sensor 210 to move leftward along the X-axis direction.

[0074] ​When the second shape-changing member 1222 is energized to be shortened and contracted, and / or the fourth shape-changing member 1224 is energized to be lengthened and relaxed, the second shape-changing member 1222 and the fourth shape-changing member 1224 can drive the moving member 121, the movable member 111 and the image sensor 210 to translate downward along the Y-axis direction. When the second shape-changing member 1222 is energized to be lengthened and relaxed, and / or the fourth shape-changing member 1224 is energized to be shortened and contracted, the second shape-changing member 1222 and the fourth shape-changing member 1224 can drive the moving member 121, the movable member 111 and the image sensor 210 to translate upward along the Y-axis direction.

[0075] When the first shape-changing member 1221 and the third shape-changing member 1223 are energized to be shortened at the same time, the first shape-changing member 1221 and the third shape-changing member 1223 can drive the moving member 121, the movable member 111 and the image sensor 210 to rotate clockwise along the diagonal line of the moving member 121 in the XOY plane. When the first shape-changing member 1221 and the third shape-changing member 1223 are energized to be lengthened at the same time, the first shape-changing member 1221 can drive the moving member 121, the movable member 111 and the image sensor 210 to rotate counterclockwise along the diagonal line of the moving member 121 in the XOY plane.

[0076] When the second shape-changing member 1222 and the fourth shape-changing member 1224 are energized to be shortened at the same time, the second shape-changing member 1222 and the fourth shape-changing member 1224 can drive the moving member 121, the movable member 111 and the image sensor 210 to rotate counterclockwise along the diagonal line of the moving member 121 in the XOY plane. When the second shape-changing member 1222 and the fourth shape-changing member 1224 are energized to be lengthened at the same time, the second shape-changing member 1222 and the fourth shape-changing member 1224 can drive the moving member 121, the movable member 111 and the image sensor 210 to rotate clockwise along the diagonal line of the moving member 121 in the XOY plane.

[0077] In the anti-shake assembly 100 of the embodiment, the first shape-changing member 1221, the second shape-changing member 1222, the third shape-changing member 1223 and the fourth shape-changing member 1224 are arranged around the moving member 121, and the plurality of shape-changing members 122 can symmetrically and uniformly control the movement of the moving member 121, so that the movement distance and direction of the moving member 121 are more controllable, and the anti-shake assembly 100 is more convenient to calculate the anti-shake parameters of the image sensor 210. Meanwhile, the plurality of shape-changing members 122 can drive the moving member 121 and the image sensor 210 to realize the translation anti-shake of the X-axis and the Y-axis, and also realize the rotation anti-shake in the XOY plane. The adaptability of the anti-shake assembly 100 can realize the anti-shake compensation in various shaking scenes, and the adaptability of the camera module 10 is more optimal.

[0078] It should be noted that the plurality of deformation members 122 can drive the moving member 121, the movable member 111 and the image sensor 210 to move in other manners in addition to moving or rotating the moving member 121, the movable member 111 and the image sensor 210 along or around the optical axis direction of the lens 300. For example, the plurality of deformation members 122 can also drive the moving member 121, the movable member 111 and the image sensor 210 to move up and down along the optical axis direction of the lens 300; or the plurality of deformation members 122 can also drive the moving member 121, the movable member 111 and the image sensor 210 to flip around the direction perpendicular to the optical axis direction of the lens 300, at this time, the arrangement of the plurality of deformation members 122 and the moving member 121 can be changed accordingly, for example, the anti-shake assembly 100 and the image sensor assembly 200 are arranged along the optical axis direction of the lens, and a reflecting mirror is arranged between the anti-shake assembly 100 and the lens 300, the reflecting mirror can deflect the light entering from the lens 300 by 90 degrees and then enter the image sensor assembly 200. The specific manner in which the plurality of deformation members 122 drive the moving member 121, the movable member 111 and the image sensor 210 to move is not limited in the embodiments of the present application.

[0079] It can be understood that the structure of the frame of the moving member 121 can be adapted to the size of the movable member 111 of the carrier plate 110, so that the moving member 121 can carry the movable member 111. The projections of the first extension 1217 and the second extension 1218 of the moving member 121 on the carrier plate 110 can be located on the fixed member 112 of the carrier plate 110, so that the quadrilateral structure enclosed by the two movable ends 123 and the two fixed ends 124 can be adapted to the size of the fixed member 112, so that the length of the plurality of deformation members 122 can be longer, and the movement stroke of the moving member 121, the movable member 111 and the image sensor 210 driven by the plurality of deformation members 122 can be larger.

[0080] The moving member 121 of the embodiments of the present application is provided with the first extension 1217 and the second extension 1218, on the one hand, the first extension 1217 and the second extension 1218 can carry the two movable ends 123; on the other hand, the first extension 1217 and the second extension 1218 make the length of the deformation member 122 larger, and the movement stroke of the moving member 121, the movable member 111 and the image sensor 210 driven by the deformation member 122 is larger, and the anti-shake compensation of the image sensor 210 by the anti-shake assembly 100 can be larger.

[0081] It can be understood that in the embodiments of the present application, Figure 9The first extension part 1217 of the moving part 121 is provided with a limiting part 180 protruding from the surface of the moving part 121 near the movable end 123, and the second extension part 1218 is also provided with a limiting part 180 protruding from the surface of the moving part 121 near the movable end 123. By providing a corresponding limiting groove 170 in the anti-shake shell 160, the anti-shake assembly 100 can meet the anti-shake compensation requirements of the first image sensor 210, and can also avoid the situation that the moving part is deflected unpredictably due to external force.

[0082] It should be noted that, Figure 4 The driving assembly of the anti-shake assembly shown controls the movement of the image sensor 210 through the deforming part 122. The principle is similar to that of Figure 9 The driving assembly of the anti-shake assembly shown controls the movement of the image sensor 210 through the deforming part 122. The principle is similar to that of

[0083] Please refer to Figures 1 to 5 The first electric connection end can be electrically connected with the image sensor 210. The second electric connection end can be electrically connected with the driving adapter plate 700 of the camera module 10 or an external circuit outside the camera module 10. When the first electric connection end and the second electric connection end are electrically connected through the electric connecting part, the image sensor 210 can be electrically connected with the driving adapter plate 700 through the first electric connection end, the electric connecting part and the second electric connection end. The driving adapter plate 700 can lead out the electrical signal of the image sensor 210 to the anti-shake assembly 100 and be electrically connected with the circuit board, power supply and other components of the camera module 10 or the electronic device.

[0084] It can be understood that since the fixed part 112 can be connected with the bottom plate 130 and is fixed, the driving adapter plate 700 electrically connected with the second electric connection end of the fixed part 112 does not need to move with the moving part 121 or the movable part 111, and the driving adapter plate 700 does not need to be bent and welded. The welding process of the driving adapter plate 700 of the embodiment of the present application is simple and the size is small.

[0085] The anti-shake assembly can also include one or more elastic parts. Please continue to refer to Figure 12 and Figure 13 , Figure 12 As Figure 5 The structure diagram of the bearing plate and the elastic part in the anti-shake assembly is shown. Figure 13 The enlarged diagram of part of the elastic part in the bearing plate and the elastic part shown in Figure 12

[0086] ​The image stabilization assembly 100 may further include one or more elastic elements 113. One or more elastic elements 113 may be disposed between the movable element 111 and the fixed element 112, for example, between the outer periphery of the movable element 111 and the inner periphery of the fixed element 112. The first end a1 of each elastic element 113 may be connected to the fixed element 112 and fixed in place, while the second end a2 may be connected to the movable element 111 and move with it. One or more elastic elements 113 may provide an elastic force opposite to the direction of movement of the movable element 111 to restrain its movement. The elastic force provided by the elastic element 113 and the driving force provided by the drive mechanism 120 can work together on the movable element 111, allowing it to remain stably in a certain position, thereby making the image stabilization control of the movable element 111 and the image sensor 210 more precise.

[0087] It is understandable that the elastic element 113 can be made of a material with elastic restoring force.

[0088] For example, such as Figure 12 As shown, the image stabilization component 100 may include four elastic elements 113, each of which can be a set of trace suspension assemblies (TSA). Multiple sets of trace suspension assemblies are arranged around the moving element 121. In related technologies, the fixed and moving parts of the support plate are connected via an FPC module. When the image sensor moves, the reaction force generated by the FPC module is very large, and the consistency after bending is difficult to guarantee. This makes the image sensor prone to tilting during movement, thus affecting the production yield of the camera module. In this embodiment, the fixed element 112 and the moving element 111 are connected via multiple sets of trace suspension assemblies. The elastic elements 113 employ TSA technology, and the trace suspension assemblies of the elastic elements 113 are processed using an exposure etching process, ensuring the consistency of the elastic coefficient of the trace suspension assemblies. This improves the consistency of the elastic elements 113 and enhances the yield of the image stabilization component 100.

[0089] To simplify the circuitry of the image stabilization component 100, camera module 10, or electronic device, one or more elastic elements 113 may be conductive electrical connectors made of a conductive material. Specifically, one end of the elastic element 113 is used for electrical connection to the image sensor 210, and the other end is used for electrical connection to external circuitry, thereby connecting the image sensor 210 and the external circuitry. For example, the elastic element 113 can be electrically connected to the pads (PADs) of the image sensor circuit board 220 via thermoforming or similar methods.

[0090] Exemplarily, the movable component 111 can be provided with a first electrical connection end directly or indirectly electrically connected with the image sensor 210, the fixed component 112 can be provided with a second electrical connection end directly or indirectly electrically connected with an external circuit, and the elastic component 113 can be directly or indirectly electrically connected with the second electrical connection end and the first electrical connection end respectively, so that the external circuit can be directly or indirectly electrically connected with the image sensor 210 through the second electrical connection end, the elastic component 113 and the first electrical connection end.

[0091] It can be understood that the first electrical connection end can be but is not limited to a pad structure on the movable component 111, and the second electrical connection end can be but is not limited to a pad structure on the fixed component 112. The external circuit can be but is not limited to electrically connected with the second electrical connection end through the driving adapter plate 700.

[0092] It can be understood that the external circuit can not only provide power supply for the image sensor 210, but also transmit control signals for the image sensor 210, so that the control chip of the camera module 10 and the control chip of the electronic device 1 can control the image sensor 210.

[0093] In the anti-shake assembly 100 of the embodiment, the external circuit can be electrically connected with the image sensor 210 through the elastic component 113, and the elastic component 113 can be used as an elastic damping component and an electrical connection component. The elastic component 113 realizes multiplexing, and the anti-shake assembly 100 does not need to additionally provide a flexible circuit board to supply power for the image sensor 210, so that the elastic component 113 of the embodiment can simplify the circuit arrangement of the anti-shake assembly 100 and realize miniaturized design of the anti-shake assembly 100.

[0094] As shown in Figure 13 Each group of suspension wire circuits can include a plurality of suspension wires 1132 arranged side by side. The plurality of suspension wires 1132 not only physically connect the fixed component 112 and the movable component 111, but also electrically connect the circuits on the fixed component 112 and the movable component 111. The plurality of suspension wires 1132 in each group of suspension wire circuits can be arranged at intervals, that is, the adjacent two suspension wires 1132 are electrically isolated at intervals, without affecting the transmission of power supply or signals by the plurality of suspension wires 1132.

[0095] Optionally, the elastic element 113 may also include, but is not limited to, various springs. Each elastic element 113 may include one or more sub-elastic elements, and each elastic element 113 may be formed by spiraling multiple elastic wires. In this case, the first end a1 of the elastic element 113 may be one end formed by multiple elastic wires, and the second end a2 may be another end formed by multiple elastic wires. Of course, in actual production, each elastic element 113 may also be formed by only one spring. The specific structure of the elastic element 113 is not limited in the embodiments of this application. Any structure of the elastic element 113 that can withstand the force generated by the movement of the movable element 111 under the drive mechanism 120 and has elastic restoring force is within the protection scope of the embodiments of this application.

[0096] It is understood that the projection of the first end a1 of each elastic element 113 onto the movable element 111 can be offset from its second end a2, for example, the two can be distributed on different sides of the movable element 111. Each elastic element 113 is connected to one side of the fixed element 112 and the other side of the movable element 111 corresponding to that side. Each elastic element 113 can form a torsion spring structure, and the multiple elastic elements 113 exert a greater pulling force on the movable element 111, which can improve the stability of the movable element 111.

[0097] It is understandable that, such as Figure 12 As shown, each elastic element 113 may include a first elastic portion b1, a first corner portion b2, and a second elastic portion b3 connected in sequence. The first elastic portion b1 may be connected to the fixed member 112, and the second elastic portion b3 may be connected to the movable member 111. The first line connecting the first elastic portion b1 and the first corner portion b2 and the second line connecting the first corner portion b2 and the second elastic portion b3 may form a preset angle, which may be, but is not limited to, ninety degrees. The elastic element 113 of this embodiment includes the above three parts. The elastic element 113 can form a torsion spring structure with a large amplitude. The elastic element 113 exerts a greater pulling force on the movable member 111, and the elastic element 113 can further ensure the stability of the movable member 111.

[0098] To further improve the stability of the moving part 111, multiple elastic elements 113 on the support plate 110 can be sequentially arranged around the outer periphery of the moving part 111. For example, such as Figure 12 As shown. Multiple elastic elements 113 can be arranged clockwise around the outer periphery of the movable element 111, and the multiple elastic elements 113 can be arranged clockwise in the order of first end, second end, first end, second end... Of course, multiple elastic elements can also be arranged counterclockwise around the outer periphery of the movable element 111, in which case the multiple elastic elements 113 can be arranged counterclockwise in the order of first end, second end, first end, second end...

[0099] In the two adjacent elastic members 113, the second end a2 of one of the elastic members 113 (for example, the elastic member 113 in front) can be adjacent to the projection of the first end a1 of the other elastic member 113 (for example, the elastic member 113 behind) on the moving member 111 and can be located on the same side of the moving member 111. It can be understood that the adjacent here means that the distance between the first end a1 of the elastic member 113 in front and the second end a2 of the elastic member 113 behind can be within a small preset range, so that the elastic torsion of the two adjacent elastic members 113 can cover the entire side of the moving member 111, and the stability of the moving member 111 is better.

[0100] When the fixed member 112 is a rectangular frame structure and the moving member 111 is a rectangular plate structure, the corresponding bearing plate 110 can include four elastic members 113, so that each elastic member 113 is connected to a side of the fixed member 112 and the adjacent side of the moving member 111 corresponding to the side, and each elastic member 113 can include a group of suspension wire circuits. On the one hand, the group of suspension wire circuits can provide traction for the movement of the moving member 111 to improve the stability of the moving member 111; on the other hand, the group of suspension wire circuits can also avoid the movement of the moving member 111 being too large to separate the elastic member 113 from the moving member 111.

[0101] It should be noted that the above is only an exemplary connection mode of the elastic member 113, the moving member 111 and the fixed member 112 of the embodiment of the present application. The specific connection mode of the elastic member 113 is not limited to the above description, for example, the elastic member 113 can also be directly connected to the side frame of the fixed member 112 and the side of the moving member 111 corresponding thereto. The specific connection mode of the elastic member 113 is not limited in the embodiment of the present application.

[0102] It should be noted that the specific structure of the anti-shake assembly 100 of the embodiment of the present application is not limited to the description of the above embodiment. For example, the anti-shake assembly 100 can also be provided with an elastic structure on the upper and lower sides of the bearing plate 110 to further improve the stability of the image sensor 210. For another example, the anti-shake assembly 100 can also use other driving modes to enable the image sensor 210 to move in other directions. The specific structure of the anti-shake assembly 100 is not limited in the embodiment of the present application.

[0103] It can be understood that the image sensor 210, the moving member 111 and the moving member 121 can be suspended on the bottom plate 130, and when the driving mechanism 120 drives the moving member 111 to move, the moving member 111 is prone to tilt during the movement, which affects the image quality of the shooting.

[0104] In some embodiments, as Figure 3As shown, the image stabilization assembly 100 may further include a support bracket 140, which is disposed between the base plate 130 and the movable member 111. The support bracket 140 can raise the movable member 111. The elastic member 113 can generate an elastic restoring force to attach the movable member 111 to the support bracket 140. The support bracket 140 is connected to the base plate 130. The moving member 121, the movable member 111 and the image sensor 210 can remain relatively stationary during movement, which can prevent the image sensor 210 from tilting during movement, improve the image stabilization effect and improve the image quality of the captured image.

[0105] Please combine Figure 14 , Figure 14 for Figure 3 The diagram shows the structure of the elevation bracket in the image stabilization assembly. The elevation bracket 140 includes an elevation base plate 142 and at least three protrusions 144. All protrusions 144 are spaced apart on the side of the elevation base plate 142 facing the movable member 111, and the surfaces of all protrusions 144 facing the movable member 111 are on the same plane. At least three protrusions 144 abut against the movable member 111. The surfaces of the at least three protrusions 144 define a plane, ensuring that the movable member 111, mounted on the at least three protrusions 144, is on a single plane, thus guaranteeing the stability of the movable member 111. Furthermore, since the movable member 111 is mounted on the elevation bracket 140 via the multiple protrusions 144, when the movable member 111 moves relative to the elevation bracket 140, it does not need to move relative to the entire elevation base plate 142, but only relative to the multiple protrusions 144, reducing the influence of the elevation bracket 140 on the movement of the movable member 111. The surface of each protrusion 144 can be a smooth surface, and the surface of the movable part 111 that contacts the multiple protrusions 144 can also be a smooth surface, so that the movable part 111 can move conveniently relative to the multiple protrusions 144.

[0106] The raised support 140 can be formed using an etching process, resulting in excellent flatness. For example, the surface of each protrusion 144 of the raised support 140 that abuts against the movable member 111 can be formed using an etching process, thus giving each protrusion 144 a surface with excellent flatness and smoothness. Alternatively, if the raised substrate 142 does not have protrusions 144 and directly abuts against the movable member 111, the surface of the raised substrate 142 that abuts against the movable member 111 can be formed using an etching process, thus giving the surface of the raised substrate 142 a surface with excellent flatness and smoothness.

[0107] Multiple protrusions 144 can be disposed in different areas of the raised substrate 142. For example, multiple protrusions 144 can be disposed at different edge positions of the raised substrate 142, or multiple protrusions 144 can be disposed at different positions in the middle of the raised substrate 142.

[0108] Optionally, a super-smooth structure can be arranged between the heightening support 140 and the movable piece 111, and the friction coefficient of the super-smooth structure can reach 10 -3 The heightening support 140 and the movable piece 111 are connected through the super-smooth structure, which can improve the sliding effect between the heightening support 140 and the movable piece 111, reduce the power consumption of the driving mechanism 120, and reduce the requirements of the driving mechanism 120. The super-smooth structure can be installed on the heightening support 140 or the movable piece 111. After the super-smooth structure is arranged between the heightening support 140 and the movable piece 111, the smoothness requirement of the surface of the movable piece 111 on the side facing the heightening support 140 can be reduced, for example, the surface of the movable piece 111 on the side facing the heightening support 140 can not be coated, and the smoothness requirement of the surface of the heightening support 140 on the side facing the movable piece can be reduced. In some examples, the heightening support 140 is provided with a plurality of protrusions 144 on the side facing the movable piece 111, and the surfaces of at least three protrusions 144 facing the movable piece 111 can be provided with the super-smooth structure. The protrusions 144 can not be formed by etching process, which reduces the difficulty of forming the protrusions 144 and reduces the cost, and at the same time, the sliding effect of the protrusions 144 and the movable piece 111 is better.

[0109] It should be noted that because the heightening support 140 lifts the movable piece 111, the height of the fixed piece 112 remains unchanged, and the movable piece 111 and the fixed piece 112 are connected through the elastic piece 113. In order to better set the moving piece 121, the moving piece 121 can be arranged on the side of the movable piece 111 away from the bottom plate 130, so as not to affect the arrangement of the fixed piece 112 and the movable piece 111.

[0110] Optionally, the movable piece 111 includes a metal layer and an insulating layer arranged in layers, the side of the insulating layer away from the substrate is used to carry the image sensor of the camera module, and the metal layer is arranged on the side of the insulating layer facing the substrate. The bottom surface of the movable piece 111 can be provided with a metal layer such as titanium copper, so that the movable piece 111 has good elasticity. A layer of insulating layer is arranged on the metal layer, which facilitates the arrangement of the image sensor on the insulating layer.

The driving adapter plate 700 can be vertically arranged, for example, perpendicular or substantially perpendicular to the bottom plate 130. The vertical arrangement of the driving adapter plate 700 on the bottom plate 130 can reduce the size of the camera module. The separate design of the driving adapter plate 700 can place the driving IC and other electronic components on the driving adapter plate 700, which is conducive to the stacking of the camera module. In addition, when the camera module is arranged on the mainboard of the electronic device, a receiving hole corresponding to the camera module is arranged on the mainboard, and the camera module is arranged in the receiving hole on the mainboard. The smaller the size of the camera module, the smaller the area of the receiving hole on the mainboard, and the larger the area of the mainboard that can arrange circuits, which is convenient for the mainboard to arrange circuits reasonably.

[0112] Optionally, the driving adapter plate 700 can be attached to the anti-shake shell 160, that is, one side of the driving adapter plate is attached to the anti-shake shell 160, which can support the driving adapter plate 700 and make the structure of the driving adapter plate 700 and the anti-shake shell 160 more compact. It should be noted that the fixing member 112 can be provided with a plurality of welding pins, and the driving adapter plate 700 is correspondingly provided with a plurality of welding pins.

The side of the module shell and the anti-shake shell 160 facing the driving adapter plate 700 can also not be flush, one of the module shell and the anti-shake shell 160 protrudes towards the driving adapter plate 700, and the driving adapter plate 700 can be attached to the protruding one of the module shell and the anti-shake shell 160. In other examples, the module shell can cover the anti-shake shell 160, that is, the anti-shake shell 160 is arranged in the module shell, and correspondingly, the driving adapter plate 700 is attached to the module shell.

The resistance feedback of the deformation piece 122 is used for control, and a hall sensor is not needed, so that the cost is lower and the structure is simpler. In the same volume of the anti-shake assembly 100, a longer deformation piece 122 can be assembled, the anti-shake assembly 100 can provide a larger working stroke, and a larger anti-shake angle can be provided.

For example, the focusing assembly 600 can drive the lens 300 to move along the optical axis direction of the lens 300.

[0116] The focusing assembly 600 can be arranged on the anti-shake assembly 100, for example, on the anti-shake housing 160 of the anti-shake assembly 100, and the focusing assembly 600 can be arranged opposite to the anti-shake assembly 100 along the optical axis direction of the lens 300, and the focusing assembly 600 and the anti-shake assembly 100 can be arranged in a stack along the first direction H1. In some embodiments, a mechanical limiting support 410 can be further arranged between the focusing assembly 600 and the anti-shake assembly 100.

[0117] The focusing assembly 600 can include a module shell and a focusing driving mechanism, the module shell can serve as a mounting housing of the focusing assembly 600, and the focusing driving mechanism can be arranged in the module shell and can drive the lens 300 to move to realize the focusing function. In some embodiments, please refer to Figure 12 , Figure 12 Another explosion structure schematic diagram of the camera module provided by the embodiment of the application.

[0118] The focusing assembly 600 can include a carrier, a magnetic component, and a conductive component. The carrier can carry the lens 300, and the carrier can be, but is not limited to, a lens 300 carrier. The magnetic component can generate a magnetic field, and the carrier 6 can be located in the magnetic field. The conductive component can be arranged opposite to the magnetic component in a direction perpendicular to the optical axis of the lens 300, and the conductive component can generate a force under the action of the magnetic component. The force can drive the carrier to move up and down along the optical axis of the lens 300. The specific structure of the magnetic component and the carrier is not limited in the embodiments of the present application.

[0119] The focusing assembly 600 according to the embodiments of the present application can drive the carrier 6 and the lens 300 to move up and down along the vertical direction through the cooperation of the magnetic component and the conductive component. The focusing assembly has a simple structure and occupies a small space, and can realize the miniaturization design of the camera module 10.

[0120] In some embodiments, the focusing assembly in the open loop mode can be selected as needed, and a small amplitude is sacrificed for the focusing speed and the stability of the focusing assembly in control is maintained. The anti-shake assembly is used to realize the anti-shake of the image sensor, and a better shooting effect can be achieved. The cost can be reduced, and the size of the camera module can be reduced.

[0121] It can be understood that in other embodiments, the camera module 10 can also not be provided with the focusing assembly 600, and the image sensor 210 can be driven to move up and down relative to the lens by the anti-shake assembly 100 to realize the focusing function. It should be noted that the specific structure of the camera module 10 according to the embodiments of the present application is not limited to the description of the above embodiments. For example, the camera module 10 can further include, but is not limited to, a micro gimbal assembly, in addition to the anti-shake assembly 100, the image sensor assembly 200, the lens 300, and the focusing assembly 600. The specific structure of the camera module 10 is not limited in the embodiments of the present application.

[0122] Optionally, the camera module can further include a lens anti-shake assembly. The lens anti-shake assembly is connected with the lens, and is used to adjust the movement of the lens to realize the anti-shake of the lens. The lens anti-shake assembly can adopt a structure similar to the magnetic component, the coil structure, and the ball structure in the above embodiments. For example, a plurality of pairs of magnetic components and coil structures, and a plurality of groups of ball structures are arranged. The movement of the lens is driven by the magnetic component and the coil structure to realize the anti-shake of the lens. For example, the lens can be driven to rotate around the axis of the lens, and can be flipped in the plane perpendicular to the axis of the lens. The movement of the lens can change and correct the optical path when the camera module shakes, and the anti-shake compensation effect can be achieved.

[0123] It can be understood that the anti-shake assembly driving the camera module to move and the lens anti-shake assembly driving the lens can respectively perform anti-shake processing on the camera module and the lens, so that five-axis anti-shake of the camera module can be achieved, specifically including Pitch (Rx), Yaw (Ry), Roll (Rz), Left / Right (X), Up / Down (Y) five-axis compensation anti-shake, wherein Rx, Ry, and Rz can be assisted by a gyroscope sensor for anti-shake, and X and Y can be assisted by an acceleration sensor for anti-shake. Illustratively, four-axis anti-shake can be achieved by compensating for the translation of X and Y or the overturning of Rx and Ry through XY direction translation. The anti-shake assembly can achieve XY translation and rotation in the XY plane of the image sensor through the pulling force of the four deformation pieces (SMA metal wires), so as to compensate for the translation of X and Y or the overturning of Rx and Ry and Rz anti-shake.

[0124] The lens and the lens anti-shake assembly can be fixed by point gluing baking, screw fixing, or clamping fixing.

The prism assembly is installed in the module shell, the prism assembly is arranged on the side of the lens away from the image sensor, and the prism assembly is fixedly connected with the module shell.

In the embodiment, the body anti-shake (i.e., image sensor anti-shake) is adopted to achieve the anti-shake of the camera module through the image sensor anti-shake, the prism can be fixedly arranged in the module shell, the size of the prism is reduced, a complex prism anti-shake structure does not need to be arranged, the cost can be reduced, and the size of the camera module is optimized.
