[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

[0038] Please refer to Figures 1, 2 and 3. Figures 1 and 2 are schematic structural diagrams of the shake correction module 10 at different angles in some embodiments, and Figure 3 is an exploded schematic diagram of the shake correction module 10 in some embodiments. The shake correction module 10 provided in the present application includes an image sensor 11, and the image sensor 11 has a photosensitive surface 111. The image sensor 11 can be used to convert the light received by the photosensitive surface 111 into image information through photoelectric conversion, thereby realizing the image capture function. The image sensor 11 includes but is not limited to a charge-coupled device sensor (CCD) or a complementary metal oxide semiconductor sensor (CMOS). In some embodiments, the camera device further includes a filter 21, and the filter 21 includes but is not limited to an infrared filter element. The filter 21 is arranged between the image sensor 11 and the lens, for example, on the image sensor 11. The filter 21 is used to filter out interference light to prevent the interference light from being projected onto the photosensitive surface 111 and affecting the image quality.

[0039] The shake correction module 10 can be used in an imaging device such as a camera. For example, the shake correction module 10 can be disposed within a housing and, together with the housing, form an imaging device. The imaging device includes a lens and an imaging device. The lens may include one or more lenses having optical power. The lens is disposed within the housing and is located on the side of the photosensitive surface 111 of the image sensor 11. When the imaging device is used for shooting, light reflected from the subject is regulated by the lens and then incident on the photosensitive surface 111 of the image sensor 11. The shake correction module 10 is used to drive the image sensor 11 to move, for example, along a first direction 191 and / or a second direction 192 to compensate for camera shake in the first direction 191 and / or the second direction 192, thereby achieving optical image stabilization and ensuring good image quality even when the imaging device is shaken. The first direction 191 and the second direction 192 can be two mutually perpendicular directions on a plane parallel to the photosensitive surface 111.

[0040] In some embodiments, the shake correction module 10 further includes a first stator assembly 12, a second stator assembly 13, and a movable assembly 14. The first stator assembly 12 and the second stator assembly 13 are interconnected, the movable assembly 14 is disposed between the first stator assembly 12 and the second stator assembly 13, and the image sensor 11 is disposed on the movable assembly 14. At least one of the first stator assembly 12 and the second stator assembly 13 is configured to drive the movable assembly 14 to move, thereby driving the image sensor 11 to move. For example, one of the first stator assembly 12 and the second stator assembly 13 can generate a magnetic force with the movable assembly 14 to drive the movable assembly 14 to move in the first direction 191 and / or the second direction 192. The first stator assembly 12 and the second stator assembly 13 can also generate a magnetic force with the movable assembly 14 to drive the movable assembly 14 to move, thereby driving the image sensor 11 to move and achieve optical image stabilization.

[0041] The above-mentioned shake correction module 10 drives the movable subassembly 14 to move through the first stator assembly 12 and / or the second stator assembly 13, thereby driving the image sensor 11 to move. It is possible to integrate the shake correction module of the camera device into the image sensor module. Compared with the method of driving the lens to move to achieve optical image stabilization, it is beneficial to reduce the size and weight of the driven object of the shake correction module 10, thereby facilitating the compression of the size of the driving structure in the first stator assembly 12 and / or the second stator assembly 13 and the movable subassembly 14. At the same time, it is also beneficial to reduce the overall occupied space of the shake correction module 10, thereby facilitating the miniaturization design of the camera device. The movable subassembly 14 is arranged between the first stator assembly 12 and the second stator assembly 13. The first stator assembly 12 and the second stator assembly 13 can jointly provide limiting and protective functions for the movable subassembly 14, which can improve the overall structural strength and functional stability of the shake correction module 10. When the first stator assembly 12 and the second stator assembly 13 drive the movable subassembly 14 to move at the same time, the driving force on the movable subassembly 14 can also be improved, which is beneficial to improve the sensitivity and accuracy of anti-shake.

[0042] As shown in conjunction with Figures 3, 4, and 5, in some embodiments, a magnetic force can be generated between the first stator assembly 12 and the mover assembly 14 to drive the mover assembly 14 to move the image sensor 11. For example, the first stator assembly 12 includes a stator substrate 121 and a first magnetic assembly 122, which is disposed on the stator substrate 121. The mover assembly 14 includes a mover substrate 141 and an electromagnetic assembly 142, which is disposed on the mover substrate 141 and the image sensor 11. The first magnetic assembly 122 is configured to drive the electromagnetic assembly 142 to move, thereby driving the mover substrate 141 to move, so that the image sensor 11 moves synchronously with the mover substrate 141. The first magnetic assembly 122 may include one or more magnetic bodies, including but not limited to any suitable magnetic element capable of generating a magnetic field, such as a magnet or a lodestone. The electromagnetic assembly 142 may include one or more electromagnetic elements, such as coils, that can generate a magnetic field when energized. When one or more coils in the electromagnetic assembly 142 are energized, a magnetic field is generated, thereby generating a magnetic force with the magnetic field of the magnetic body in the first magnetic assembly 122, thereby driving the electromagnetic assembly 142 to move relative to the first magnetic assembly 122, so that the movable substrate 141 drives the image sensor 11 to move relative to the stator substrate 121.

[0043] In some embodiments, the first magnetic assembly 122 includes a first magnetic body 1221 and a second magnetic body 1222, and the electromagnetic assembly 142 includes a first coil 1421 and a second coil 1422. The first magnetic body 1221 is opposite to the first coil 1421, and the second magnetic body 1222 is opposite to the second coil 1422. The first magnetic body 1221 and the first coil 1421 can both extend along the second direction 192. When the first coil 1421 is energized, the magnetic force generated between the first magnetic body 1221 and the first coil 1421 can drive the first coil 1421 to move relative to the first magnetic body 1221 in the first direction 191. The second magnetic body 1222 and the second coil 1422 can both extend along the first direction 191. When the second coil 1422 is energized, the magnetic force generated between the second magnetic body 1222 and the second coil 1422 can drive the second coil 1422 to move relative to the first magnetic body 1221 in the second direction 192.

[0044] The cooperation between the first magnetic component 122 and the electromagnetic component 142 can drive the movable sub-substrate 141 to move the image sensor 11 along the first direction 191 and / or the second direction 192. It will be understood that when one of the first coil 1421 and the second coil 1422 is energized, the movable sub-substrate 141 can be driven to move in one of the first direction 191 and the second direction 192. When the first coil 1421 and the second coil 1422 are energized at the same time, the movable sub-substrate 141 can be driven to move in the first direction 191 and the second direction 192 simultaneously, thereby compensating for the jitter of the image sensor 11 in one or both of the first direction 191 and the second direction 192.

[0045] The number of first magnetic bodies 1221 and second magnetic bodies 1222 is not limited to one. In some embodiments, at least one of the first magnetic bodies 1221 and the second magnetic bodies 1222 may be provided with at least two. When at least two first magnetic bodies 1221 are provided, the at least two first magnetic bodies 1221 are sequentially arranged along the second direction 192. Correspondingly, at least two first coils 1421 may also be provided, and the at least two first coils 1421 are sequentially arranged along the second direction 192 and are arranged relative to the first magnetic bodies 1221 in a one-to-one correspondence. Multiple first coils 1421 can be energized simultaneously, generating magnetic forces between the multiple first coils 1421 and the multiple first magnetic bodies 1221, thereby increasing the driving force of the first stator assembly 12 on the movement of the mover assembly 14 in the first direction 191 and improving the movement sensitivity and accuracy of the image sensor 11 in the first direction 191. When there are at least two second magnetic bodies 1222, the at least two second magnetic bodies 1222 are sequentially arranged along the first direction 191. Correspondingly, there may also be at least two second coils 1422, which are sequentially arranged along the first direction 191 and are arranged relative to the second magnetic bodies 1222 in a one-to-one correspondence. The plurality of second coils 1422 can be energized simultaneously, generating magnetic forces between the plurality of second coils 1422 and the plurality of second magnetic bodies 1222. This increases the driving force of the first stator assembly 12 on the mover assembly 14 in the second direction 192, thereby improving the movement sensitivity and accuracy of the image sensor 11 in the second direction 192.

[0046] In some embodiments, when at least two second magnetic bodies 1222 are provided, the current flowing in the at least two second coils 1422 may not be identical. For example, in the case of two magnetic bodies, the two second magnetic bodies 1222 are arranged sequentially along the first direction 191, with their magnetic poles arranged in the same direction. The two second coils 1422 are positioned opposite the two second magnetic bodies 1222, respectively. When the two second coils 1422 are energized, the current flowing in the two second coils 1422 may be identical or opposite. When the current flowing in the two second coils 1422 is identical, the two second magnetic bodies 1222 simultaneously drive the two second coils 1422 to move in the second direction 192. When the currents flowing through the two second coils 1422 are in opposite directions, the magnetic forces between the two second magnetic bodies 1222 and the two second coils 1422 are in opposite directions. The two sets of second magnetic bodies 1222 and the two second coils 1422 cooperate to drive the movable substrate 141 to rotate about an axis parallel to the third direction 193, that is, within a plane parallel to the first direction 191 and the second direction 192, thereby meeting various optical image stabilization requirements. The third direction 193 can be perpendicular to both the first direction 191 and the second direction 192. The first stator assembly 12, the movable assembly 14, and the second stator assembly 13 are arranged sequentially along the third direction 193.

[0047] Of course, the number of second magnetic bodies 1222 is not limited to two, and can be greater. When multiple second magnetic bodies 1222 are arranged sequentially along the first direction 191, the current flow directions of at least two or more of them are different, thereby driving the movable substrate 141 to rotate. The number of first magnetic bodies 1221 and first coils 1421 is also not limited. When the rotation of the movable substrate 141 is achieved by at least two second magnetic bodies 1222, there can be only one first magnetic body 1221. When there are at least two first magnetic bodies 1221, the current flow directions of the at least two first magnetic bodies 1221 can also be different, thereby driving the movable substrate 141 to rotate.

[0048] As shown in conjunction with Figures 3, 6, 7, and 8, in some embodiments, the second stator assembly 13 includes a stator cover 131 and a second magnetic assembly 132. The stator cover 131 is connected to the stator base plate 121 to cooperate with the stator base plate 121 to provide positioning, support, and protection for the movable assembly 14. The second magnetic assembly 132 cooperates with the first magnetic assembly 122 to drive the movable assembly 14 to move the image sensor 11. The second magnetic assembly 132 may include a third magnetic body 1321 and a fourth magnetic body 1322. The third magnetic body 1321 is opposite to the first coil 1421 and can cooperate with the first magnetic body 1221 to drive the first coil 1421 to move in the first direction 191. The fourth magnetic body 1322 is opposite to the second coil 1422 and can cooperate with the second magnetic body 1222 to drive the second coil 1422 to move in the second direction 192. The number of third magnetic bodies 1321 is equal to the number of first coils 1421 and first magnetic bodies 1221. The number of fourth magnetic bodies 1322 is equal to the number of second coils 1422 and second magnetic bodies 1222. The specific configuration of third magnetic bodies 1321 and fourth magnetic bodies 1322 can be referenced with the configuration of first magnetic bodies 1221 and second magnetic bodies 1222, and will not be further described in this application. Magnetic assemblies are provided in both first stator assembly 12 and second stator assembly 13, which together drive electromagnetic assembly 142 to move, thereby driving movement of movable substrate 141. This can increase the driving force of shake correction module 10 on image sensor 11, thereby improving the sensitivity and accuracy of image stabilization.

[0049] In some embodiments, the stator cover 131 may be substantially L-shaped, with a portion of the stator cover 131 extending along the first direction 191 and covering the second coil 1422, and another portion extending along the second direction 192 and covering the first coil 1421. The photosensitive surface 111 of the image sensor 11 avoids the stator cover 131, and the image sensor 11 or the image control element 112 electrically connected to the image sensor 11 may at least partially overlap the thickness of the stator cover 131. This can reduce the size of the shake correction module 10, facilitate miniaturization of the camera module, and also provide protection for the electromagnetic assembly 142. Of course, the second magnetic component 132 may not be provided in the second stator component 13. The jitter correction module 10 only drives the movable component 14 to move through the first electromagnetic component 142. Then the second stator component 13 mainly provides limiting, supporting and protecting functions for the movable component 14 through the stator cover 131. At this time, the material of the stator cover 131 may include magnetic isolation material. The stator cover 131 can provide magnetic isolation for the magnetic fields of the first magnetic component 122 and the electromagnetic component 142, so that the magnetic fields of the first magnetic component 122 and the electromagnetic component 142 can fully act to provide a stronger driving force to the movable substrate 141, thereby improving the sensitivity and accuracy of anti-shake.

[0050] In other embodiments, the positions of the magnetic body and the coil may be differently arranged. For example, a magnetic body may be provided on the movable substrate 141, while a coil may be provided on at least one of the stator substrate 121 and the stator cover 131. When the coil on at least one of the stator substrate 121 and the stator cover 131 is energized, it can generate a magnetic force with the magnetic body on the movable substrate 141, driving the movable substrate 141 to move, thereby similarly achieving the optical image stabilization function of the image sensor 11. It should be noted that in this embodiment, when coils are provided on both the stator substrate 121 and the stator cover 131, the shake correction module 10 can selectively energize the coil on one of the stator substrate 121 and the stator cover 131, or can energize the coils on both the stator substrate 121 and the stator cover 131 simultaneously to increase the driving force for the movement of the movable substrate 141, thereby enriching the control and functionality of the shake correction module 10.

[0051] In some embodiments, the first magnetic body 1221, the second magnetic body 1222, the third magnetic body 1321 and the fourth magnetic body 1322 may include two magnets with different magnetization directions (not shown in the figure). The magnets include but are not limited to magnetic elements such as magnets or magnets. By setting two magnets with different magnetization directions, the magnetic fields generated by the two magnets can cooperate with each other to enhance the magnetic field strength of the formed magnetic body, thereby enhancing the driving force generated on the electromagnetic component 142, which is also beneficial to improving the sensitivity and accuracy of the movement of the movable component 14.

[0052] As shown in Figures 4, 5, and 9, the shake correction module 10 further includes a rolling element 151 and a tensioning assembly. The rolling element 151 is rollably disposed on the side of the stator substrate 121 facing the movable substrate 141 and engages with the movable substrate 141 in a rolling manner. The rolling element 151 includes, but is not limited to, a ball bearing or other element capable of engaging with the movable substrate 141 in a rolling manner. The tensioning assembly includes a tensioning magnetic body 152 and a tensioning fitting 153. One of the tensioning magnetic body 152 and the tensioning fitting 153 is disposed on the movable substrate 141, and the other is disposed on the stator substrate 121. The tensioning magnetic body 152 and the tensioning fitting 153 generate a magnetic attraction force, thereby tensioning the stator substrate 121 and the movable substrate 141 against each other through the magnetic attraction force, maintaining a close fit between the movable substrate 141 and the rolling element 151, thereby preventing the movable substrate 141 from separating from the rolling element 151 and affecting the movement accuracy of the movable substrate 141.

[0053] The tensioning magnetic body 152 includes, but is not limited to, a magnetic element such as a magnet or a lodestone disposed on the stator substrate 121. The tensioning fitting 153 includes, but is not limited to, an element such as a steel sheet easily magnetized and disposed on the mover substrate 141, or a magnetic element such as a magnet or a lodestone capable of generating a magnetic field. As long as a magnetic attraction force can be generated between the tensioning magnetic body 152 and the tensioning fitting 153, the mover substrate 141 and the stator substrate 121 are tensioned by the rolling element 151 and the tensioning assembly, allowing the mover substrate 141 to smoothly roll with the rolling element 151 to move relative to the stator substrate 121. Compared to the method of tensioning the mover substrate 141 and the stator substrate 121 with a spring or a tension spring, the tensioning assembly is less likely to fail due to severe impact, and is less likely to be affected by deformation of the spring or tension spring, thus improving the anti-shake accuracy and anti-shake effect.

[0054] The number of rolling elements 151 is not limited, as long as they can roll with the movable substrate 141 to enable stable movement of the movable substrate 141 relative to the stator substrate 121. Referring to FIG5 , in some embodiments, the shake correction module 10 includes three rolling elements 151, one of which is positioned between the first magnetic body 1221 and the second magnetic body 1222. Another rolling element 151 is positioned at either end of the second magnetic body 1222 in the first direction 191, and another rolling element 151 is positioned at either end of the first magnetic body 1221 in the second direction 192. The three rolling elements 151 form a three-point support structure for the movable substrate 141, enabling stable movement of the movable substrate 141 relative to the stator substrate 121. Furthermore, the three rolling elements 151, in conjunction with the first magnetic assembly 122, fully utilize the space within the stator substrate 121, minimizing the size of the stator substrate 121. Of course, four, five, or other numbers of rolling elements 151 may also be provided, and this is not a limitation in this application.

[0055] Of course, in other embodiments, the jitter correction module 10 may also be provided with a plurality of spaced tension springs or springs or other tensioning elements to achieve tensioning of the movable substrate 141 and the stator substrate 121, or tension springs or springs and rolling elements 151 may be provided at the same time to achieve more stable and effective tensioning.

[0056] In some embodiments, a rolling groove 1411 is provided on the side of the movable substrate 141 facing the stator substrate 121. The shake correction module 10 further includes a rolling gasket 1412 provided on the bottom wall of the rolling groove 1411. The rolling element 151 is partially located within the rolling groove 1411 and rolls with the rolling gasket 1412. The provision of the rolling gasket 1412 can reduce friction during the rolling engagement between the rolling element 151 and the movable substrate 141, thereby reducing wear on the rolling element 151 and improving the stability of the movement of the movable substrate 141. At the same time, the sidewalls of the rolling groove 1411 can limit the rolling element 151, preventing it from disengaging from the rolling groove 1411, thereby improving the structural and functional stability of the shake correction module 10.

[0057] As shown in conjunction with Figures 3 and 10 , in some embodiments, the shake correction module 10 further includes a position detection component 154. This position detection component 154 may be disposed within the movable assembly 14 and configured to detect the displacement of the movable assembly 14 relative to the first and second stator assemblies 12 and 13, thereby detecting the displacement of the image sensor 11. This facilitates monitoring the displacement of the image sensor 11 and improving anti-shake accuracy. In some embodiments, the position detection component 154 includes a Hall effect sensor disposed on the movable substrate 141 and configured to sense changes in the magnetic field of the first and second magnetic assemblies 122 and 132. It will be appreciated that when the movable substrate 141 moves the image sensor 11 relative to the first and second stator assemblies 12 and 13, the position of the position detection component 154 relative to the first and second magnetic assemblies 122 and 132 also changes, causing the magnetic field strength sensed by the position detection component 154 to change. Thus, by sensing this change in magnetic field strength, the displacement of the image sensor 11 can be determined.

[0058] In some embodiments, the position detection component 154 is provided with multiple Hall sensors, which are disposed in a one-to-one correspondence within the first coil 1421 and the second coil 1422. For example, when the electromagnetic component 142 has one first coil 1421 and two second coils 1422, the position detection component 154 is provided with three Hall sensors, one of which is located within the first coil 1421, and the other two Hall sensors are located within the two second coils 1422. Thus, the three Hall sensors are respectively opposed to the three magnetic bodies of the first magnetic component 122 and the three magnetic bodies of the second magnetic component 132, and can more sensitively sense changes in the magnetic field strength of the first magnetic component 122 and the second magnetic component 132. The three Hall sensors cooperate with each other to improve the displacement sensing accuracy of the image sensor 11. Of course, the setting of the position detection component 154 is not limited to the Hall sensor. The position detection component 154 may also include a TMR (Tunnel Magnetoresistance Effect) magnetic sensor. The TMR magnetic sensor can also be used to sense the change in magnetic field strength of the first magnetic component 122 and the second magnetic component 132. The position detection component 154 may also include any other applicable mechanical sensors, optical sensors, etc., as long as it can sense the displacement change of the image sensor 11 relative to the first stator component 12 and the second stator component 13.

[0059] With reference to Figures 10, 11, and 12, in some embodiments, the shake correction module 10 further includes a position-limiting connector 161 and a position-limiting cover plate 162. The position-limiting connector 161 includes, but is not limited to, a connecting element such as a screw or a pin. The stator substrate 121 is provided with a position-limiting hole 1211. The position-limiting connector 161 is fixedly connected to the mover substrate 141 and penetrates the stator substrate 121 through the position-limiting hole 1211. A portion of the position-limiting connector 161 is located on the side of the stator substrate 121 facing away from the mover substrate 141. The position-limiting cover plate 162 is connected to the position-limiting connector 161 on the side of the stator substrate 121 facing away from the mover substrate 141. The radial dimension of the position-limiting cover plate 162 is greater than the radial dimension of the position-limiting hole 1211, so that the position-limiting cover plate 162 can abut the stator substrate 121 on the side of the stator substrate 121 facing away from the mover substrate 141. Therefore, the limiting cover plate 162 and the limiting connector 161 cooperate to provide a limiting effect on the stator substrate 121 and the mover substrate 141 in the third direction 193 , thereby improving the structural stability and functional stability of the shake correction module 10 .

[0060] In some embodiments, the shake correction module 10 further includes a flexible stopper 163, which is mounted on the stopper connector 161 and at least partially located within the stopper hole 1211. The flexible stopper 163 includes, but is not limited to, a flexible element such as soft rubber. When the movable substrate 141 moves relative to the stator substrate 121, it drives the stopper connector 161 to move within the stopper hole 1211. When the movable substrate 141 moves to a maximum travel position relative to the stator substrate 121, the flexible stopper 163 can abut against the inner wall of the stopper hole 1211, thereby limiting the movement of the movable substrate 141 in the first direction 191 and the second direction 192, thereby improving the stability of the anti-shake function. In addition, the use of a flexible element as the flexible stopper 163 can cushion collisions when contacting the inner wall of the stopper hole 1211, thereby reducing the risk of damage to the shake correction module 10.

[0061] In some embodiments, a plurality of limiting posts 1413 are protruding from the side of the movable substrate 141 facing the stator cover 131. The limiting posts 1413 abut the side of the stator cover 131 facing the movable substrate 141 to limit the movable substrate 141 and the stator cover 131 in the third direction 193. For example, two limiting posts 1413 may be provided, one abutting a portion of the stator cover 131 extending along the first direction 191, and the other abutting a portion of the stator cover 131 extending along the second direction 192. This not only achieves effective limiting, but also reduces the number of components in the shake correction module 10 and the size of the shake correction module 10.

[0062] As shown in conjunction with Figures 4, 9, and 13, in some embodiments, the shake correction module 10 further includes a first heat conductor 171. The first heat conductor 171 includes, but is not limited to, thermally conductive graphite. The two ends of the first heat conductor 171 are respectively connected to the movable substrate 141 and the housing of the camera device. For example, one end of the first heat conductor 171 is connected to the movable substrate 141, and the other end is fixed to the housing of the camera device via screws and a mounting bracket 172. The first heat conductor 171 can conduct heat from the movable substrate 141 to the housing, thereby transferring heat generated by components such as the image sensor 11, image control element 112, and circuit components on the movable substrate 141, thereby achieving a heat dissipation effect for the shake correction module 10 and preventing damage to the components due to excessive temperature. As shown in Figure 13, the first heat conducting member 171 is generally elongated and has at least one curved corner along its extension direction. The first heat conducting member 171 is made of a flexible material. As the end of the first heat conducting member 171 connected to the movable substrate 141 moves relative to the stator substrate 121, the curved corner of the first heat conducting member 171 also adapts to the change. This reduces the space occupied by the first heat conducting member 171 and reduces the resistance it creates to the movement of the movable substrate 141, making anti-shake more sensitive.

[0063] Referring again to Figures 3 and 4, in some embodiments, the mover assembly 14 further includes an electromagnetic circuit element 143, which includes but is not limited to a flexible printed circuit board (FPC) or a signal transmission line. One end of the electromagnetic circuit element 143 can be electrically connected to the multiple coils in the electromagnetic assembly 142 in sequence via wires. The other end of the electromagnetic circuit element 143 extends out of the shake correction module 10 to electrically connect to components such as the mainboard or central processing unit of the camera device to power and control the coils in the electromagnetic assembly 142. The shake correction module 10 further includes an image control element 112 and an image circuit element 113. The image control element 112 includes but is not limited to a control circuit board for the image sensor 11, which is used to receive the image signal generated by the image sensor 11. The image control element 112 is disposed on the mover substrate 141 and electrically connected to the image sensor 11. The image circuit element 113 includes but is not limited to a flexible printed circuit (FPC) or a signal transmission line. One end of the image circuit element 113 is electrically connected to the image control element 112, and the other end extends outside the shake correction module 10 and is electrically connected to the motherboard or central processing unit of the camera device to transmit the image signal generated by the image control element 112.

[0064] Furthermore, in some embodiments, the electromagnetic circuit element 143 and the image control element 112 are respectively disposed at both ends of the movable substrate 141 in the first direction 191. That is, the two ends of the movable substrate 141 in the first direction 191 are electrically connected to the components on the movable substrate 141. The first heat conductor 171 is located between the electromagnetic circuit element 143 and the image circuit element 113 in the first direction 191. In some embodiments, the electromagnetic circuit element 143 and the image circuit element 113 extend along the first direction 191. In other words, the electromagnetic circuit element 143 and the image circuit element 113 extend from the movable substrate 141 in two opposite directions in the first direction 191, respectively, to form the shake correction module 10. The first heat conductor 171 extends along the second direction 192. Therefore, the extension directions of the first heat conductor 171, the electromagnetic circuit element 143 and the image circuit element 113 and their arrangement positions on the movable substrate 141 do not interfere with each other, which can avoid the first heat conductor 171, the electromagnetic circuit element 143 and the image circuit element 113 from interfering with each other during the movement of the movable substrate 141 relative to the stator substrate 121, thereby improving the stability and accuracy of the movement of the movable substrate 141.

[0065] As shown in Figures 2, 3 and 5, in some embodiments, the image circuit element 113 and the electromagnetic circuit element 143 respectively extend the jitter correction module 10 from opposite sides of the movable substrate 141. For example, the electromagnetic circuit element 143 is electrically connected to the electromagnetic component 142 on the side of the movable substrate 141 facing away from the stator substrate 121 and extends the jitter correction module 10. The image circuit element 113 passes through the movable substrate 141 from the side of the movable substrate 141 toward the stator substrate 121 and is electrically connected to the image control element 112, and extends the jitter correction module 10, which can further reduce the risk of interference between the electromagnetic circuit element 143 and the image circuit element 113.

[0066] In some embodiments, the stator substrate 121 defines a through-slot 1212. A first heat conductor 171 is connected to the side of the movable substrate 141 facing the stator substrate 121. Both the first heat conductor 171 and the image circuit component 113 extend through the through-slot 1212. The first heat conductor 171 is connected to the camera housing on the side of the stator substrate 121 facing away from the movable substrate 141. The image circuit component 113 extends out of the camera housing from the side of the stator substrate 121 facing away from the movable substrate 141. This arrangement improves the space utilization efficiency of the camera module 10, reduces the overall space occupied by the camera module 10, and facilitates the miniaturization of the camera. In some embodiments, the shake correction module 10 may further include a fixing frame 181, which is fixedly connected to the side of the stator substrate 121 facing away from the movable substrate 141 by fixing elements such as screws, so as to fix part of the image circuit element 113 between the fixing frame 181 and the stator substrate 121, so that when the image circuit element 113 is pulled, it will not affect the connection stability between the image circuit element 113 and the image control element 112.

[0067] As shown in Figures 14, 15 and 16, in some embodiments, the image control element 112 is arranged on the side of the movable substrate 141 facing away from the stator substrate 121, and the image sensor 11 is arranged on the side of the image control element 112 facing away from the movable substrate 141. This is beneficial to reducing the space occupied by the image sensor 11 and the image control element 112 on the movable substrate 141, thereby helping to compress the size of the jitter correction module 10, and is also beneficial to improving the electrical connection stability between the image sensor 11 and the image control element 112.

[0068] In some embodiments, the image control element 112 is provided with a heat conducting groove 1121, and the shake correction module 10 further includes a second heat conducting member 173. The second heat conducting member 173 is at least partially provided in the heat conducting groove 1121, and the two opposite sides of the second heat conducting member 173 are in contact with the image sensor 11 and the movable substrate 141 respectively. The second heat conducting member 173 can conduct the heat generated by the image sensor 11 and the image control element 112 to the movable substrate 141, and then conduct it to the housing of the camera device through the first heat conducting member 171, thereby achieving the effect of heat dissipation and cooling. In addition, the heat conducting groove 1121 is provided in the image control element 112 to accommodate the second heat conducting member 173, which can reduce the space occupied by the second heat conducting member 173, improve the space utilization efficiency of the shake correction module 10, and achieve a good heat dissipation effect while being conducive to the miniaturization design of the camera device.

[0069] As shown in conjunction with Figures 10 and 14 , in some embodiments, the shake correction module 10 further includes a third heat conducting member 174. The third heat conducting member 174 includes a first heat conducting portion 1741 and a second heat conducting portion 1742 that are interconnected. The first heat conducting portion 1741 is at least partially disposed on the side of the image control element 112 facing away from the movable substrate 141 and contacts the surface of the image control element 112 facing away from the movable substrate 141. The second heat conducting portion 1742 is disposed around the image control element 112 and the movable substrate 141 and contacts the side surfaces of the image control element 112 and the movable substrate 141. Thus, the third heat conducting member 174 can conduct heat generated by the image control element 112 to the movable substrate 141, and then conduct the heat to the housing of the imaging device through the first heat conducting member 171, achieving a heat dissipation and cooling effect.

[0070] As shown in Figures 10, 11, and 14, in some embodiments, the shake correction module 10 further includes a fourth heat conductor 175. The fourth heat conductor 175 covers the electromagnetic assembly 142 and contacts the movable substrate 141. The fourth heat conductor 175 can dissipate the heat generated by the electromagnetic assembly 142 to the movable substrate 141, thereby conducting the heat to the housing of the camera device through the first heat conductor 171, thereby achieving a heat dissipation and cooling effect. In some embodiments, the movable substrate 141 is provided with a plurality of wire slots 1414, and the plurality of coils of the electromagnetic assembly 142 are arranged in a one-to-one correspondence within the wire slots 1414. One end face of the coil is flush with one surface of the movable substrate 141, for example, flush with the surface of the movable substrate 141 facing away from the stator substrate 121. The fourth heat conductor 175 is attached to the surface of the movable substrate 141 facing away from the stator substrate 121 and the end face of the coil, and covers the plurality of coils. Such a configuration is beneficial for reducing the overall occupied space of the movable subassembly 14 and the fourth heat conducting member 175 , and is beneficial for miniaturization of the shake correction module 10 .

[0071] In some embodiments, the fourth heat conducting member 175 can be generally L-shaped and include a third heat conducting portion 1751 and a fourth heat conducting portion 1752 interconnected with each other. The third heat conducting portion 1751 extends along the second direction 192 and covers the first coil 1421, while the fourth heat conducting portion 1752 extends along the first direction 191 and covers the plurality of second coils 1422. This compresses the fourth heat conducting member 175 while also improving the heat dissipation effect of the fourth heat conducting member 175 on the electromagnetic assembly 142. In some embodiments, at least a portion of the electromagnetic circuit element 143 is positioned between the electromagnetic assembly 142 and the fourth heat conducting member 175 to electrically connect the fourth heat conducting member 175, which covers the electromagnetic circuit element 143. Thus, the fourth heat conducting member 175 can simultaneously dissipate heat for the electromagnetic circuit element 143 and provide a position-limiting and securing function for the electromagnetic circuit element 143, thereby improving the stability of the electrical connection between the electromagnetic circuit element 143 and the electromagnetic assembly 142.

[0072] In some embodiments, the shake correction module 10 may further include a plurality of fifth heat-conducting members 176, which may be spaced apart between the image control element 112 and the movable substrate 141 to conduct heat generated by the image control element 112 to the movable substrate 141, thereby cooperating with the third heat-conducting member 174 to improve the heat dissipation effect of the image control element 112. It is understood that by providing multiple heat-conducting members such as the first heat-conducting member 171, the second heat-conducting member 173, the third heat-conducting member 174, the fourth heat-conducting member 175, and the fifth heat-conducting member 176, the heat dissipation effect of the movable subassembly 14, the image sensor 11, and the image control element 112 can be effectively improved, thereby improving the heat dissipation and cooling performance. At the same time, the space occupied by the multiple heat-conducting members can be reduced, thereby improving the space utilization efficiency of the shake correction module 10 and facilitating the miniaturization design of the imaging device. The materials of the above-mentioned thermal conductive elements include but are not limited to thermal conductive materials such as graphite or metal with good thermal conductivity. The movable substrate 141 can also be made of materials such as aluminum alloy or magnesium alloy with good thermal conductivity and sufficient structural strength. As long as a good heat dispersion effect can be achieved and the heat dissipation effect of the device can be improved, it is not limited in this application.

[0073] As shown in conjunction with Figures 3 and 17 , in some embodiments, the shake correction module 10 further includes a connector 182, including but not limited to fixing elements such as nuts. The ends of the connector 182 are respectively fixedly connected to the stator base plate 121 and the stator cover plate 131, thereby relatively fixing the first stator assembly 12 and the second stator assembly 13. In some embodiments, the shake correction module 10 further includes a buffer 183, including but not limited to a soft cushioning rubber. The buffer 183 covers at least the portion of the connector 182 corresponding to the rotor assembly 14 in the third direction 193. Therefore, when the movable substrate 141 moves relative to the stator substrate 121 in the first direction 191 and / or the second direction 192 to abut the buffer 183, the cooperation between the buffer 183 and the connecting member 182 can provide a limiting effect on the movable substrate 141 in the first direction 191 and the second direction 192, thereby improving the stability of the movement of the movable substrate 141. At the same time, the buffer 183 can also buffer the impact force of the movable substrate 141, thereby reducing the risk of damage to the movable substrate 141.

[0074] The number of connectors 182 and buffers 183 is not limited, as long as they can achieve a stable connection between the stator substrate 121 and the stator cover 131 and effectively limit the position of the movable substrate 141. In some embodiments, three connectors 182 are provided, distributed at three corners of the stator substrate 121, and three buffers 183 are provided accordingly, with each buffer 183 correspondingly positioned on each connector 182. This ensures a stable connection between the stator substrate 121 and the stator cover 131 while simultaneously limiting the position of the movable substrate 141 from multiple corners, thereby improving the structural and functional stability of the shake correction module 10.

[0075] In some embodiments, a notch 1415 is defined around the periphery of the movable substrate 141. The connector 182 is partially positioned within the notch 1415, and the buffer 183 is at least partially positioned within the portion of the connector 182 corresponding to the notch 1415. Thus, the connector 182 and the buffer 183 effectively limit the movable substrate 141 while also reducing the size of the movable substrate 141, thereby facilitating a miniaturized design of the shake correction module 10. For example, when three connectors 182 are provided, three notches 1415 may be defined at each of the three corners of the movable substrate 141, with the connectors 182 positioned within the notches 1415 in a one-to-one correspondence.

[0076] As shown in Figures 17, 18, and 19, in some embodiments, the first stator assembly 12 further includes a yoke 123, which is disposed on the side of the stator base facing away from the mover base and covers the first magnetic body 1221 and the second magnetic body 1222. The provision of the yoke 123 can provide magnetic isolation for the first magnetic assembly 122, thereby enhancing the interaction between the first magnetic assembly 122 and the electromagnetic assembly 142, and improving the sensitivity and accuracy of driving the mover substrate 141. In some embodiments, the first stator assembly 12 further includes a bracket 124, which is disposed on the side of the stator substrate 121 facing away from the mover substrate 141 and is provided with a plurality of mounting positions 1241. The stator substrate 121 is provided with a plurality of magnet slots 1213, and the mounting positions 1241 are arranged in a one-to-one correspondence with the magnet slots 1213. The first magnetic body 1221 and the second magnetic body 1222 are correspondingly positioned in the mounting position 1241 and partially housed within the magnet slot 1213. The yoke 123 is connected to the side of the bracket 124 facing away from the stator substrate 121. Thus, the coordination of the bracket 124, the yoke 123, and the stator substrate 121 enhances the mounting strength of the first magnetic assembly 122 on the stator substrate 121, thereby improving the structural stability of the shake correction module 10. Of course, the yoke 123 can be replaced with any other suitable magnetic isolation element, as long as it can enhance the magnetic field interaction between the first magnetic assembly 122 and the electromagnetic assembly 142. This is not a limitation in this application.

[0077] As shown in FIG. 19 , in some embodiments, the yoke 123 may be generally L-shaped, with a portion of the yoke 123 extending along the second direction 192 and covering the first magnetic body 1221, while another portion extends along the first direction 191 and covering the second magnetic body 1222. The bracket 124 may also be configured to be generally L-shaped to accommodate the shape of the yoke 123. In some embodiments, the fixing bracket 181 is positioned away from the yoke 123 and the bracket 124, and the fixing bracket 181 and the yoke 123 are disposed together around the three edges of the through-slot 1212. By rationally configuring the position and structure of each component, the space utilization efficiency of the shake correction module 10 is improved, facilitating a compact design of the shake correction module 10.

[0078] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
