Description

Technical Field

[0001] This application relates to the field of camera stabilization technology, and in particular to a shake correction module, camera device, and camera equipment. Background Technology

[0002] Cameras and other video recording devices often face the problem of image quality being affected by camera shake during shooting. To solve this problem, traditional video recording devices usually have a shake correction module to compensate for image changes caused by shake. However, the shake correction module in traditional video recording devices occupies a large space, which is not conducive to the miniaturization design of video recording devices. Summary of the Invention

[0003] Therefore, it is necessary to address the issue of large space occupation of shake correction modules in traditional camera equipment by providing a shake correction module, camera device, and camera equipment.

[0004] A jitter correction module, comprising:

[0005] First stator assembly;

[0006] The second stator assembly is connected to the first stator assembly;

[0007] A moving part is disposed between the first stator part and the second stator part;

[0008] An image sensor is disposed on the moving part assembly, and the photosensitive surface of the image sensor faces away from the first stator assembly;

[0009] At least one of the first stator assembly and the second stator assembly is configured to drive the mover assembly to move the image sensor.

[0010] The aforementioned shake correction module, by driving the mover assembly to move through the first stator assembly and / or the second stator assembly, thereby moving the image sensor, integrates the shake correction module of the camera device into the image sensing module. This helps reduce the size and weight of the driven object of the shake correction module, thus compressing the size of the driving structure in the stator and mover assemblies, reducing the overall space occupied by the shake correction module, and facilitating the miniaturization design of the camera device. The mover assembly, located between the first and second stator assemblies, enhances the overall structural strength and functional stability of the shake correction module. When both the first and second stator assemblies simultaneously drive the mover assembly, it also increases the driving force on the mover assembly, thereby improving the sensitivity and accuracy of image stabilization.

[0011] A camera device includes a housing and a shake correction module as described above, wherein the shake correction module is disposed within the housing.

[0012] A camera device includes a lens and a camera assembly as described above, wherein the lens is disposed in the housing and located on the side of the photosensitive surface of the image sensor. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 and Figure 2 These are schematic diagrams of the jitter correction module 10 at different angles in some embodiments. Figure 3This is an exploded view of the shake correction module 10 in some embodiments. The shake correction module 10 provided in this application includes an image sensor 11, which 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 (CCD) sensor or a complementary metal-oxide-semiconductor (CMOS) sensor. In some embodiments, the imaging device also includes a filter 21, which includes, but is not limited to, an infrared filter element. The filter 21 is disposed between the image sensor 11 and the lens, for example, disposed on the image sensor 11. The filter 21 is used to filter out interference light and prevent interference light from hitting the photosensitive surface 111 and affecting the image quality.

[0041] The image shake correction module 10 can be used in camera and other imaging devices. For example, the image shake correction module 10 can be housed inside a housing and together with the housing form an imaging device. The imaging device includes a lens and an imaging mechanism. The lens may include one or more lenses with optical power. The lens is housed in the housing and located on the side where the photosensitive surface 111 of the image sensor 11 is located. When the imaging device is used to take a picture, the light reflected from the subject is adjusted by the lens and then projected onto the photosensitive surface 111 of the image sensor 11. The image shake correction module 10 is used to drive the image sensor 11 to move, for example, to drive the image sensor 11 to move along a first direction 191 and / or a second direction 192, to compensate for the shaking of the imaging device in the first direction 191 and / or the second direction 192, thereby achieving optical image stabilization and enabling the imaging device to obtain good shooting quality even when shaking. The first direction 191 and the second direction 192 can be two mutually perpendicular directions on a plane parallel to the photosensitive surface 111.

[0042] In some embodiments, the shake correction module 10 further includes a first stator assembly 12, a second stator assembly 13, and a mover assembly 14. The first stator assembly 12 and the second stator assembly 13 are interconnected, and the mover assembly 14 is disposed between the first stator assembly 12 and the second stator assembly 13. The image sensor 11 is disposed on the mover assembly 14. At least one of the first stator assembly 12 and the second stator assembly 13 is configured to drive the mover assembly 14 to move the image sensor 11. For example, one of the first stator assembly 12 and the second stator assembly 13 can generate a magnetic force with the mover assembly 14 to drive the mover assembly 14 to move along a first direction 191 and / or a second direction 192. Alternatively, both the first stator assembly 12 and the second stator assembly 13 can generate a magnetic force with the mover assembly 14 to drive the mover assembly 14 to move, thereby moving the image sensor 11 to achieve optical image stabilization.

[0043] The aforementioned shake correction module 10 drives the mover assembly 14 to move through the first stator assembly 12 and / or the second stator assembly 13, thereby moving the image sensor 11. This allows the shake correction module of the camera device to be integrated into the image sensing module. Compared to the method of driving the lens to achieve optical image stabilization, this method is beneficial to reduce the size and weight of the driven object of the shake correction module 10, thereby reducing the size of the driving structure in the first stator assembly 12 and / or the second stator assembly 13 and the mover assembly 14. It also helps to reduce the overall space occupied by the shake correction module 10, thus facilitating the miniaturization design of the camera device. The moving part 14 is located between the first stator part 12 and the second stator part 13. The first stator part 12 and the second stator part 13 can jointly provide limiting and protection for the moving part 14, which can improve the overall structural strength and functional stability of the jitter correction module 10. When the first stator part 12 and the second stator part 13 drive the moving part 14 to move at the same time, it can also increase the driving force on the moving part 14, thereby helping to improve the sensitivity and accuracy of jitter correction.

[0044] Combination Figure 3 , Figure 4 and Figure 5As shown, 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 component 122, which is disposed on the stator substrate 121. The mover assembly 14 includes a mover substrate 141 and an electromagnetic component 142, which is disposed on the mover substrate 141. The first magnetic component 122 is configured to drive the electromagnetic component 142 to move, thereby moving the mover substrate 141, so that the image sensor 11 moves synchronously with the mover substrate 141. The first magnetic component 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 lodestone. The electromagnetic component 142 may include one or more electromagnetic elements such as coils that can be energized to generate a magnetic field. When one or more coils in the electromagnetic component 142 are energized, they can generate a magnetic field, which in turn generates a magnetic force with the magnetic field of the magnetic body in the first magnetic component 122, thereby driving the electromagnetic component 142 to move relative to the first magnetic component 122, so that the moving substrate 141 drives the image sensor 11 to move relative to the stator substrate 121.

[0045] In some embodiments, the first magnetic component 122 includes a first magnetic body 1221 and a second magnetic body 1222, and the electromagnetic component 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 may both extend along a 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 along a first direction 191. The second magnetic body 1222 and the second coil 1422 may 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 along a second direction 192.

[0046] The cooperation of the first magnetic component 122 and the electromagnetic component 142 enables the moving sub-subplate 141 to drive the image sensor 11 to move along the first direction 191 and / or the second direction 192. It is understood that when one of the first coil 1421 and the second coil 1422 is energized, the moving sub-subplate 141 can be driven to move along one of the first direction 191 and the second direction 192. When both the first coil 1421 and the second coil 1422 are energized simultaneously, the moving sub-subplate 141 can be driven to simultaneously generate displacement in the first direction 191 and the second direction 192, thereby compensating for jitter in one or both of the first and second directions 191 and 192 of the image sensor 11.

[0047] 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 second magnetic bodies 1222 may be provided with at least two. When there are at least two first magnetic bodies 1221, the at least two first magnetic bodies 1221 are arranged sequentially along the second direction 192. Correspondingly, there may also be at least two first coils 1421, which are arranged sequentially along the second direction 192 and are arranged in a one-to-one correspondence with the first magnetic bodies 1221. The multiple first coils 1421 can be energized simultaneously, so that magnetic forces are generated 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 at least two second magnetic bodies 1222 are provided, the at least two second magnetic bodies 1222 are sequentially arranged along the first direction 191. Correspondingly, at least two second coils 1422 can also be provided, the at least two second coils 1422 are sequentially arranged along the first direction 191, and are arranged in a one-to-one correspondence with the second magnetic bodies 1222. Multiple second coils 1422 can be energized simultaneously, so that magnetic forces are generated between the multiple second coils 1422 and the multiple second magnetic bodies 1222, thereby increasing the driving force of the first stator assembly 12 on the movement of the mover assembly 14 in the second direction 192, and improving the movement sensitivity and accuracy of the image sensor 11 in the second direction 192.

[0048] In some embodiments, when at least two second magnetic bodies 1222 are provided, the current flow directions of the at least two second coils 1422 are not entirely the same. Taking two magnetic bodies as an example, the two second magnetic bodies 1222 are arranged sequentially along the first direction 191, and the magnetic poles are arranged in the same direction. The two second coils 1422 are respectively arranged opposite to the two second magnetic bodies 1222, and when the two second coils 1422 are energized, the current flow directions of the two second coils 1422 can be the same or opposite. When the current flow directions of the two second coils 1422 are the same, the two second magnetic bodies 1222 simultaneously drive the two second coils 1422 to move along the second direction 192. When the current flows in opposite directions in the two second coils 1422, 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 mover substrate 141 to rotate around an axis parallel to a third direction 193, that is, to rotate in a plane parallel to the first direction 191 and the second direction 192, so as to meet more 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 mover assembly 14, and the second stator assembly 13 are arranged sequentially along the third direction 193.

[0049] Of course, the number of second magnetic bodies 1222 is not limited to two, and there can be more. 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 not exactly the same, so as to drive the moving substrate 141 to rotate. The number of first magnetic bodies 1221 and first coils 1421 is also not limited. When the rotation of the moving substrate 141 is achieved by at least two second magnetic bodies 1222, there can be 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, so as to drive the moving substrate 141 to rotate.

[0050] Combination Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the second stator assembly 13 includes a stator cover plate 131 and a second magnetic assembly 132. The stator cover plate 131 is connected to the stator substrate 121 to cooperate with the stator substrate 121 to provide limiting, support, and protection for the mover assembly 14. The second magnetic assembly 132 cooperates with the first magnetic assembly 122 to drive the mover 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 along a 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 along a second direction 192. The number of third magnetic bodies 1321 is equal to the number of first coils 1421 and first magnetic bodies 1221, and the number of fourth magnetic bodies 1322 is equal to the number of second coils 1422 and second magnetic bodies 1222. The specific arrangement of the third magnetic bodies 1321 and fourth magnetic bodies 1322 can be referred to the first magnetic bodies 1221 and second magnetic bodies 1222, which will not be repeated in this application. Magnetic components are provided in both the first stator assembly 12 and the second stator assembly 13, which together drive the electromagnetic component 142 to move, thereby driving the mover substrate 141 to move. This can improve the driving force of the jitter correction module 10 on the movement of the image sensor 11, thereby improving the sensitivity and accuracy of image stabilization.

[0051] In some embodiments, the stator cover 131 may be generally L-shaped, with a portion extending along a first direction 191 and covering the second coil 1422, and another portion extending along a 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 with the thickness of the stator cover 131. This reduces the size of the jitter correction module 10, facilitating miniaturization of the camera module, and also provides protection for the electromagnetic components 142. Of course, the second magnetic component 132 may not be provided in the second stator assembly 13. The jitter correction module 10 drives the mover assembly 14 to move only through the first electromagnetic component 142. In this case, the second stator assembly 13 mainly provides limiting, support and protection for the mover assembly 14 through the stator cover plate 131. At this time, the material of the stator cover plate 131 may include magnetic shielding material. The stator cover plate 131 can provide magnetic shielding 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 exert a stronger driving force on the mover base plate 141, thereby improving the sensitivity and accuracy of jitter correction.

[0052] In other embodiments, the positions of the magnet and the coil can be arranged differently. For example, a magnet can be provided on the moving substrate 141, while a coil is provided on at least one of the stator substrate 121 and the stator cover plate 131. When the coil on at least one of the stator substrate 121 and the stator cover plate 131 is energized, it can generate a magnetic force with the magnet on the moving substrate 141, thereby driving the moving substrate 141 to move. This also enables the optical image stabilization function of the image sensor 11. It should be noted that in this embodiment, when both the stator substrate 121 and the stator cover plate 131 are provided with coils, the jitter correction module 10 can selectively supply power to the coil on one of the stator substrate 121 and the stator cover plate 131, or it can simultaneously energize the coils on both the stator substrate 121 and the stator cover plate 131 to increase the driving force for the movement of the moving substrate 141, thus enriching the control and functions of the jitter correction module 10.

[0053] 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 each 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 ferrites. By setting two magnets with different magnetization directions, the magnetic fields generated by the two magnets can cooperate with each other to increase the magnetic field strength of the formed magnetic body, thereby increasing the driving force generated on the electromagnetic component 142. This also helps to improve the sensitivity and accuracy of the movement of the mover component 14.

[0054] Combination Figure 4 , Figure 5 and Figure 9 As shown, the jitter correction module 10 also includes a rolling element 151 and a tensioning assembly. The rolling element 151 is rotatably disposed on the side of the stator substrate 121 facing the moving substrate 141 and rolls with the moving substrate 141. The rolling element 151 includes, but is not limited to, elements such as balls that can roll with the moving substrate 141. The tensioning assembly includes a tensioning magnet 152 and a tensioning engagement member 153. One of the tensioning magnet 152 and the tensioning engagement member 153 is disposed on the moving substrate 141, and the other is disposed on the stator substrate 121. A magnetic attraction force can be generated between the tensioning magnet 152 and the tensioning engagement member 153, thereby pulling the stator substrate 121 and the moving substrate 141 together through the magnetic attraction force, so that the moving substrate 141 is kept in close contact with the rolling element 151, preventing the moving substrate 141 from detaching from the rolling element 151 and affecting the movement accuracy of the moving substrate 141.

[0055] The tensioning magnet 152 includes, but is not limited to, magnetic elements such as magnets or magnets disposed on the stator substrate 121. The tensioning mating part 153 includes, but is not limited to, elements such as easily magnetized steel sheets disposed on the mover substrate 141, or magnetic elements such as magnets or magnets capable of generating a magnetic field, as long as a magnetic attraction force can be generated between the tensioning magnet 152 and the tensioning mating part 153. The tensioning of the mover substrate 141 and the stator substrate 121 is achieved by the cooperation of the rolling element 151 and the tensioning assembly, so that the mover substrate 141 can smoothly roll and cooperate with the rolling element 151 to move relative to the stator substrate 121. Compared with the method of tensioning the mover substrate 141 and the stator substrate 121 by springs or tension springs, the tensioning assembly is less likely to fail due to severe impact, and is less likely to affect the positional accuracy between the mover substrate 141 and the stator substrate 121 due to the deformation of springs or tension springs, which is beneficial to improving the anti-shake accuracy and anti-shake effect.

[0056] The number of rolling elements 151 is not limited, as long as they can roll in cooperation with the moving base plate 141, allowing the moving base plate 141 to move stably relative to the stator base plate 121. (Reference) Figure 5 As shown, in some embodiments, the jitter correction module 10 has three rolling elements 151. One rolling element 151 is located between the first magnetic body 1221 and the second magnetic body 1222, and another rolling element 151 is located at both ends of the second magnetic body 1222 in a first direction 191. Yet another rolling element 151 is located at both ends of the first magnetic body 1221 in a second direction 192. The cooperation of the three rolling elements 151 provides three-point support for the moving substrate 141, allowing the moving substrate 141 to move stably relative to the stator substrate 121. Furthermore, the positional cooperation between the three rolling elements 151 and the first magnetic component 122 fully utilizes the space of the stator substrate 121, minimizing the need to increase its size. Of course, four, five, or other numbers of rolling elements 151 can also be provided; this application does not limit the specific number.

[0057] Of course, in other embodiments, the jitter correction module 10 may also be provided with multiple spaced tension springs or other tensioning elements to achieve tension between the moving substrate 141 and the stator substrate 121, or tension springs or other springs and rolling elements 151 may be provided at the same time to achieve more stable and effective tension.

[0058] In some embodiments, the moving substrate 141 has a rolling groove 1411 on the side facing the stator substrate 121. The jitter correction module 10 also includes a rolling pad 1412 disposed on the bottom wall of the rolling groove 1411. The rolling member 151 is partially located in the rolling groove 1411 and rolls with the rolling pad 1412. The rolling pad 1412 can reduce the friction between the rolling member 151 and the moving substrate 141 during the rolling engagement process, reduce the wear of the rolling member 151 and improve the stability of the moving substrate 141's movement. At the same time, the side wall of the rolling groove 1411 can limit the rolling member 151 and prevent the rolling member 151 from disengaging from the rolling groove 1411, which is beneficial to improving the structural stability and functional stability of the jitter correction module 10.

[0059] Combination Figure 3 and Figure 10 As shown, in some embodiments, the jitter correction module 10 further includes a position detection component 154. The position detection component 154 can be disposed in the mover assembly 14 and is used to detect the displacement of the mover assembly 14 relative to the first stator assembly 12 and the second stator assembly 13, so as to detect the displacement of the image sensor 11, which is beneficial for monitoring the displacement of the image sensor 11 and improving the jitter stabilization accuracy. In some embodiments, the position detection component 154 includes a Hall sensor, which is disposed on the mover substrate 141 and is used to sense the magnetic field changes of the first magnetic component 122 and the second magnetic component 132. It can be understood that when the mover substrate 141 drives the image sensor 11 to move relative to the first stator assembly 12 and the second stator assembly 13, the position of the position detection component 154 relative to the first magnetic component 122 and the second magnetic component 132 will also change, causing the magnetic field strength sensed by the position detection component 154 to change. Therefore, by sensing the change in magnetic field strength by the position detection component 154, the displacement of the image sensor 11 can be obtained.

[0060] In some embodiments, the position detection component 154 is provided with a plurality of Hall sensors, each corresponding to a first coil 1421 and a 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 in the first coil 1421, and the other two are located in the two second coils 1422 respectively. Thus, the three Hall sensors are respectively opposite to the three magnetic bodies of the first magnetic component 122 and the three magnetic bodies of the second magnetic component 132, enabling more sensitive sensing of changes in the magnetic field strength of the first magnetic component 122 and the second magnetic component 132. The cooperation of the three Hall sensors can improve the displacement sensing accuracy of the image sensor 11. Of course, the position detection component 154 is not limited to Hall sensors. 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 sensor, optical sensor, 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.

[0061] refer to Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the jitter correction module 10 further includes a limiting connector 161 and a limiting cover plate 162. The limiting connector 161 includes, but is not limited to, connecting elements such as screws and pins. The stator substrate 121 is provided with a limiting hole 1211. The limiting connector 161 is fixedly connected to the moving substrate 141 and passes through the limiting hole 1211 into the stator substrate 121. A portion of the limiting connector 161 is located on the side of the stator substrate 121 facing away from the moving substrate 141. The limiting cover plate 162 is connected to the limiting connector 161 on the side of the stator substrate 121 facing away from the moving substrate 141, and the radial dimension of the limiting cover plate 162 is larger than the radial dimension of the limiting hole 1211, so that the limiting cover plate 162 can abut against the stator substrate 121 on the side of the stator substrate 121 facing away from the moving substrate 141. Therefore, the limiting cover 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 jitter correction module 10.

[0062] In some embodiments, the jitter correction module 10 further includes a flexible limiting member 163, which is sleeved on the limiting connector 161 and at least partially located within the limiting hole 1211. The flexible limiting member 163 includes, but is not limited to, flexible elements such as soft rubber. When the moving substrate 141 moves relative to the stator substrate 121, it drives the limiting connector 161 to move within the limiting hole 1211. When the moving substrate 141 moves relative to the stator substrate 121 to the maximum stroke position, the flexible limiting member 163 can abut against the inner wall of the limiting hole 1211, providing a limiting effect on the movement of the moving substrate 141 in the first direction 191 and the second direction 192, which is beneficial to improving the stability of the anti-shake function. Moreover, using a flexible element as the flexible limiting member 163 can buffer the collision when contacting the inner wall of the limiting hole 1211, reducing the risk of damage to the jitter correction module 10.

[0063] In some embodiments, a plurality of limiting posts 1413 are protruding from the side of the mover substrate 141 facing the stator cover plate 131. The limiting posts 1413 abut against the side of the stator cover plate 131 facing the mover substrate 141 to provide limiting for the mover substrate 141 and the stator cover plate 131 in a third direction 193. For example, two limiting posts 1413 may be provided, one abutting against the portion of the stator cover plate 131 extending along the first direction 191, and the other abutting against the portion of the stator cover plate 131 extending along the second direction 192. This achieves effective limiting while also reducing the number of components in the jitter correction module 10 and compressing the size of the jitter correction module 10.

[0064] Combination Figure 4 , Figure 9 and Figure 13 As shown, in some embodiments, the jitter correction module 10 further includes a first heat-conducting element 171. The first heat-conducting element 171 includes, but is not limited to, thermally conductive graphite. Both ends of the first heat-conducting element 171 are respectively connected to the moving substrate 141 and the housing of the camera device. For example, one end of the first heat-conducting element 171 is connected to the moving substrate 141, and the other end is fixed to the housing of the camera device by screws and a mounting bracket 172. The first heat-conducting element 171 can conduct heat from the moving substrate 141 to the housing, thereby transferring heat generated by devices such as the image sensor 11, image control element 112, and circuit elements on the moving substrate 141, achieving a heat dissipation effect for the jitter correction module 10 and preventing damage to the devices due to excessive temperature. (Reference) Figure 13As shown, the first heat-conducting element 171 is generally elongated, and has at least one bending angle in its extending direction. The first heat-conducting element 171 is made of a flexible material. When one end of the first heat-conducting element 171 connected to the moving substrate 141 moves relative to the stator substrate 121 with the moving substrate 141, the bending angle of the first heat-conducting element 171 also changes accordingly. This reduces the space occupied by the first heat-conducting element 171 and also reduces the resistance generated by the first heat-conducting element 171 to the movement of the moving substrate 141, making the anti-shake more sensitive.

[0065] Please see again. Figure 3 and Figure 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 multiple coils in the electromagnetic assembly 142 in sequence via wires. The other end of the electromagnetic circuit element 143 extends to the jitter correction module 10 for electrical connection to components such as the motherboard or central processing unit of the camera device, so as to realize the power supply and control of the coils in the electromagnetic assembly 142. The jitter correction module 10 also 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 of the image sensor 11 for receiving 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. Image line element 113 includes, but is not limited to, flexible circuit board (FPC) or signal transmission line. One end of image line element 113 is electrically connected to image control element 112, and the other end extends to outside the jitter correction module 10 and is electrically connected to the motherboard or central processing unit of the camera device to transmit the image signal formed by image control element 112.

[0066] Further, in some embodiments, the electromagnetic circuit element 143 and the image control element 112 are respectively disposed at both ends of the moving substrate 141 in the first direction 191, that is, the two ends of the moving substrate 141 in the first direction 191 are electrically connected to the devices on the moving substrate 141, and the first heat-conducting element 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 moving substrate 141 in two opposite directions of the first direction 191 to form the jitter correction module 10, and the first heat-conducting element 171 extends along the second direction 192. Therefore, the extension directions of the first heat-conducting element 171, the electromagnetic circuit element 143, and the image circuit element 113, as well as their positions on the moving substrate 141, do not interfere with each other. This avoids interference between the first heat-conducting element 171, the electromagnetic circuit element 143, and the image circuit element 113 during the movement of the moving substrate 141 relative to the stator substrate 121, thereby improving the stability and accuracy of the movement of the moving substrate 141.

[0067] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, image circuit element 113 and electromagnetic circuit element 143 extend jitter correction modules 10 from opposite sides of the moving substrate 141. For example, electromagnetic circuit element 143 is electrically connected to electromagnetic component 142 on the side of moving substrate 141 facing away from stator substrate 121 and extends jitter correction module 10. Image circuit element 113 passes through moving substrate 141 towards stator substrate 121 and is electrically connected to image control element 112, extending jitter correction module 10. This can further reduce the risk of interference between electromagnetic circuit element 143 and image circuit element 113.

[0068] In some embodiments, the stator substrate 121 has a through slot 1212, and a first heat-conducting element 171 is connected to the side of the moving substrate 141 facing the stator substrate 121. Both the first heat-conducting element 171 and the image circuit element 113 pass through the through slot 1212. The first heat-conducting element 171 is connected to the housing of the camera device on the side of the stator substrate 121 facing away from the moving substrate 141. The image circuit element 113 extends from the side of the stator substrate 121 facing away from the moving substrate 141 to form the shake correction module 10. This arrangement helps to improve the space utilization efficiency of the shake correction module 10, reduce the overall space occupied by the shake correction module 10, and facilitates the miniaturization design of the camera device. In some embodiments, the jitter 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 moving 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 the connection stability between the image circuit element 113 and the image control element 112 will not be affected when the image circuit element 113 is pulled.

[0069] Combination Figure 14 , Figure 15 and Figure 16 As shown, in some embodiments, the image control element 112 is disposed on the side of the moving substrate 141 facing away from the stator substrate 121, and the image sensor 11 is disposed on the side of the image control element 112 facing away from the moving substrate 141. This is beneficial to reduce the space occupied by the image sensor 11 and the image control element 112 on the moving substrate 141, thereby helping to compress the size of the jitter correction module 10, and also helping to improve the electrical connection stability between the image sensor 11 and the image control element 112.

[0070] In some embodiments, the image control element 112 is provided with a heat-conducting groove 1121, and the jitter correction module 10 further includes a second heat-conducting element 173. The second heat-conducting element 173 is at least partially disposed within the heat-conducting groove 1121, and its opposite sides are in contact with the image sensor 11 and the moving substrate 141, respectively. The second heat-conducting element 173 can conduct the heat generated by the image sensor 11 and the image control element 112 to the moving substrate 141, thereby conducting it through the first heat-conducting element 171 to the housing of the camera device, achieving a heat dissipation and cooling effect. Furthermore, by providing a heat-conducting groove 1121 in the image control element 112 to accommodate the second heat-conducting element 173, the space occupied by the second heat-conducting element 173 can be reduced, improving the space utilization efficiency of the jitter correction module 10, and facilitating the miniaturization design of the camera device while achieving a good heat dissipation effect.

[0071] Combination Figure 10 and Figure 14As shown, in some embodiments, the jitter correction module 10 further includes a third heat-conducting element 174. The third heat-conducting element 174 includes a first heat-conducting portion 1741 and a second heat-conducting portion 1742 connected to each other. The first heat-conducting portion 1741 is at least partially disposed on the side of the image control element 112 facing away from the moving sub-substrate 141 and is in contact with the surface of the image control element 112 facing away from the moving sub-substrate 141. The second heat-conducting portion 1742 is disposed on the periphery of the image control element 112 and the moving sub-substrate 141 and is in contact with the side surfaces of the image control element 112 and the moving sub-substrate 141. Thus, the third heat-conducting element 174 can conduct the heat generated by the image control element 112 to the moving sub-substrate 141, and then conduct it to the housing of the camera device through the first heat-conducting element 171, achieving the effect of heat dissipation and cooling.

[0072] Combination Figure 10 , Figure 11 and Figure 14 As shown, in some embodiments, the jitter correction module 10 further includes a fourth heat-conducting element 175. The fourth heat-conducting element 175 covers the electromagnetic component 142 and contacts the moving substrate 141. The fourth heat-conducting element 175 can dissipate the heat generated by the electromagnetic component 142 to the moving substrate 141, thereby conducting it to the housing of the camera device through the first heat-conducting element 171, achieving the effect of heat dissipation and cooling. In some embodiments, the moving substrate 141 has multiple slots 1414, and multiple coils of the electromagnetic component 142 are correspondingly disposed in the slots 1414. One end face of the coil is flush with one surface of the moving substrate 141, for example, flush with the surface of the moving substrate 141 facing away from the stator substrate 121. The fourth heat-conducting element 175 is attached to the surface of the moving substrate 141 facing away from the stator substrate 121 and the end face of the coil, and covers the multiple coils. This arrangement is beneficial to the overall space occupied by the compression actuator assembly 14 and the fourth heat conduction component 175, and also to the miniaturization design of the vibration correction module 10.

[0073] In some embodiments, the fourth heat-conducting element 175 may be generally L-shaped. The fourth heat-conducting element 175 includes a third heat-conducting portion 1751 and a fourth heat-conducting portion 1752 connected to each other. The third heat-conducting portion 1751 extends along a second direction 192 and covers the first coil 1421, while the fourth heat-conducting portion 175 extends along a first direction 191 and covers a plurality of second coils 1422. This design, while compressing the fourth heat-conducting element 175, helps to improve the heat dissipation effect of the fourth heat-conducting element 175 on the electromagnetic component 142. In some embodiments, at least a portion of the electromagnetic circuit element 143 is located between the electromagnetic component 142 and the fourth heat-conducting element 175 to electrically connect the fourth heat-conducting element 175, and the fourth heat-conducting element 175 covers the electromagnetic circuit element 143. Therefore, the fourth heat-conducting element 175 can also simultaneously dissipate heat from the electromagnetic circuit element 143 and provide a limiting and fixing function for the electromagnetic circuit element 143, improving the electrical connection stability between the electromagnetic circuit element 143 and the electromagnetic component 142.

[0074] In some embodiments, the jitter correction module 10 may further include a plurality of fifth heat-conducting elements 176, which may be spaced apart between the image control element 112 and the moving substrate 141 to conduct the heat generated by the image control element 112 to the moving substrate 141, thereby improving the heat dissipation effect on the image control element 112 in conjunction with the third heat-conducting element 174. It is understood that by providing a plurality of heat-conducting elements such as the first heat-conducting element 171, the second heat-conducting element 173, the third heat-conducting element 174, the fourth heat-conducting element 175, and the fifth heat-conducting element 176, the heat dissipation effect of the moving component 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, it can also reduce the space occupied by the plurality of heat-conducting elements, improve the space utilization efficiency of the jitter correction module 10, and facilitate the miniaturization design of the camera device. The materials of the aforementioned heat-conducting elements include, but are not limited to, graphite or metal, which have good thermal conductivity. The moving substrate 141 may also be made of aluminum alloy or magnesium alloy, which have good thermal conductivity and sufficient structural strength. As long as it can achieve good heat dissipation and improve the heat dissipation effect of the device, it is not limited in this application.

[0075] Combination Figure 3 and Figure 17As shown, in some embodiments, the jitter correction module 10 further includes a connector 182, which includes, but is not limited to, a nut or other fixing element. The two ends of the connector 182 are respectively fixedly connected to the stator substrate 121 and the stator cover plate 131, so that the first stator assembly 12 and the second stator assembly 13 are relatively fixed. In some embodiments, the jitter correction module 10 further includes a buffer 183, which includes, but is not limited to, a soft cushioning rubber, etc. The buffer 183 at least covers the portion of the connector 182 corresponding to the stator assembly 14 in the third direction 193. Therefore, when the moving substrate 141 moves relative to the stator substrate 121 in the first direction 191 and / or the second direction 192 to abut the buffer member 183, the cooperation between the buffer member 183 and the connector 182 can provide a limiting effect on the moving substrate 141 in the first direction 191 and the second direction 192, thereby improving the stability of the movement of the moving substrate 141. At the same time, the buffer member 183 can also buffer the impact force of the moving substrate 141, reducing the risk of damage to the moving substrate 141.

[0076] 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 plate 131, and effectively limit the movement substrate 141. In some embodiments, three connectors 182 are provided, distributed at the three corners of the stator substrate 121, and three buffers 183 are also provided accordingly, each buffer 183 being disposed on a corresponding connector 182. While achieving a stable connection between the stator substrate 121 and the stator cover plate 131, the buffers can simultaneously limit the movement substrate 141 from multiple corners, improving the structural and functional stability of the jitter correction module 10.

[0077] In some embodiments, the peripheral edge of the moving substrate 141 is provided with a notch 1415, the connector 182 is partially located within the notch 1415, and the buffer 183 is at least partially sleeved on the portion of the connector 182 corresponding to the notch 1415. Thus, the connector 182 and the buffer 183 effectively limit the moving substrate 141 while also helping to compress the size of the moving substrate 141, which is beneficial for the miniaturization design of the jitter correction module 10. For example, when there are three connectors 182, three notches 1415 can be provided at the three corners of the moving substrate 141, and the connectors 182 are correspondingly located within the notches 1415.

[0078] Combination Figure 17 , Figure 18 and Figure 19As shown, in some embodiments, the first stator assembly 12 further includes a magnetic yoke 123, which is disposed on the side of the stator substrate 121 facing away from the mover substrate 141 and covers the first magnetic body 1221 and the second magnetic body 1222. The magnetic yoke 123 provides magnetic shielding for the first magnetic component 122, thereby allowing for more complete interaction between the first magnetic component 122 and the electromagnetic component 142, improving the sensitivity and accuracy of driving the mover substrate 141. In some embodiments, the first stator assembly 12 further includes a support 124, which is disposed on the side of the stator substrate 121 facing away from the mover substrate 141 and has multiple mounting positions 1241. The stator substrate 121 has multiple magnet slots 1213, and the mounting positions 1241 and magnet slots 1213 are arranged opposite each other. The first magnetic component 1221 and the second magnetic component 1222 are correspondingly disposed in the mounting position 1241 and partially housed within the magnetic groove 1213. The magnetic yoke 123 is connected to the side of the bracket 124 facing away from the stator substrate 121. Thus, the cooperation between the bracket 124, the magnetic yoke 123, and the stator substrate 121 enhances the mounting strength of the first magnetic component 122 on the stator substrate 121, thereby improving the structural stability of the jitter correction module 10. Of course, the magnetic yoke 123 can also be replaced by any other suitable magnetic shielding element, as long as it can enhance the magnetic field interaction force between the first magnetic component 122 and the electromagnetic component 142; this application does not impose any limitations on this.

[0079] refer to Figure 19 As shown, in some embodiments, the magnetic 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, and another portion extending along the first direction 191 and covering the second magnetic body 1222. The support 124 may also be adapted to the shape of the magnetic yoke 123 and be generally L-shaped. In some embodiments, the fixing frame 181 avoids the positions of the magnetic yoke 123 and the support 124, and the fixing frame 181 and the magnetic yoke 123 are arranged together around the three edges of the through groove 1212. By reasonably configuring the position and structure of each component, it is beneficial to improve the space utilization efficiency of the jitter correction module 10 and to the miniaturization design of the jitter correction module 10.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
