[0129] SUMMARY

[0130] The camera module needs to meet the requirement of small volume, and also needs to meet the requirement of various functions such as optical image stabilization and auto focusing. In order to meet the requirement of various functions such as optical image stabilization and auto focusing, corresponding components need to be configured. In theory, the components will be more and more, the structure of the camera module will become more and more complex, and the overall size and overall weight of the camera module are also difficult to control within a certain range, which is contrary to the requirement of small volume of the camera module.

[0131] The present application minimizes the height dimension of the driving device from the overall structure design and component layout of the driving device, and further minimizes the height dimension of the camera module.

[0132] Specifically, in the present application, the support of the carrier for image stabilization, i.e. the outer frame, is achieved by adopting a single-layer rolling support assembly, which can reduce the height dimension of the driving device for the camera module to a certain extent compared with adopting a double-layer support assembly. In the present application, the support stability is ensured even if a single-layer rolling support assembly is adopted by setting transverse guide grooves in different directions.

[0133] Based on this, the application provides a driving device for a camera module, which comprises a base, an outer frame, an inner carrier, a first driving assembly, a second driving assembly, a first supporting assembly and a second supporting assembly.

[0135] After introducing the basic principles of the application, various non-limiting embodiments of the application will be specifically introduced below with reference to the accompanying drawings.

[0136] Illustrative camera module and driving device for camera module

[0137] As shown in FIGS. 1-25, a camera module 100 and a driving device 1 for the camera module 100 according to embodiments of the application are illustrated.

[0138] Specifically, as shown in FIG. 25, the camera module 100 comprises an optical lens 2, a driving device 1 for the camera module 100 and a photosensitive assembly 3. The driving device 1 for the camera module 100 is mounted on the photosensitive assembly 3. The optical lens 2 is mounted on the driving device 1 for the camera module 100 and is located on a photosensitive path of the photosensitive assembly 3.

[0139] The driving device 1 for the camera module 100 is used to drive the optical lens 2 to move, so as to realize the functions of automatic focusing and optical image stabilization.

[0140] The photosensitive assembly 3 comprises a chip circuit board, a photosensitive chip and at least one electronic component. The photosensitive surface of the photosensitive chip faces the optical lens 2 to receive the light emitted from the optical lens 2. In a specific example, the photosensitive chip is fixed to one side of the chip circuit board facing the optical lens 2. At least one of the electronic components can be implemented as a passive electronic device such as a capacitor, a resistor, etc. or an active electronic device such as a diode, a memory chip, etc. At least one of the electronic components can be arranged on the side of the chip circuit board facing the optical lens 2. In a specific example, the photosensitive chip is electrically connected to the chip circuit board through at least one lead wire.

[0141] In some examples of the present application, the camera module 100 further comprises a filter assembly arranged on the photosensitive path of the photosensitive assembly 3, so that the camera module 100 can filter out unnecessary stray light (for example, infrared light) through the filter assembly. For example, the filter assembly is arranged between the optical lens 2 and the photosensitive assembly 3. In a specific example, the filter assembly comprises a bracket and a filter element. The bracket is supported on the chip circuit board, and the filter element is fixed to the bracket.

[0142] As shown in FIGS. 1 and 2 and FIGS. 12 and 13, the driving device 1 for the camera module 100 includes an outer housing 10, an outer frame 20, an inner carrier 30, a first driving assembly 40, a second driving assembly 50, a first supporting assembly 60, and a second supporting assembly 70. The outer frame 20 is received in the outer housing 10. The inner carrier 30 is received in the outer frame 20 and is configured to mount an optical lens 2 therein. The inner carrier 30 is further configured to be adapted to move along a set optical axis direction D relative to the outer frame 20. The outer frame 20 is configured to be adapted to move along a first direction D1 and a second direction D2 relative to the outer housing 10 and to drive the inner carrier 30 to move along the first direction D1 and the second direction D2. The first driving assembly 40 is configured to drive the inner carrier 30 to move along the optical axis direction D relative to the outer frame 20 for auto-focusing. The second driving assembly 50 is configured to drive the outer frame 20 to move along the first direction D1 and the second direction D2 relative to the outer housing 10 and to drive the inner carrier 30 and the optical lens 2 to move along the first direction D1 and the second direction D2 through the outer frame 20 for optical image stabilization. The first direction D1 and the second direction D2 are perpendicular to the optical axis direction D, and the first direction D1 and the second direction D2 are perpendicular to each other. The first supporting assembly 60 is used to guide the inner carrier 30 to move along the optical axis direction D. The second supporting assembly 70 is used to guide the outer frame 20 to move along the first direction D1 and the second direction D2.

[0143] The present application defines the optical axis direction D by the optical lens 2. The optical axis direction D of the optical lens 2 refers to the direction in which the optical lens 2 conducts light. The height direction of the camera module 100 and the height direction of the driving device 1 for the camera module 100 are consistent with the optical axis direction D.

[0144] It is worth mentioning that the present application adopts an inner focusing and outer optical image stabilization design, that is, the first driving assembly 40 and the inner carrier 30 for auto-focusing are arranged in the second driving assembly 50 and the outer frame 20 for optical image stabilization. Such a design helps to improve the auto-focusing accuracy and the component arrangement flexibility of optical image stabilization, as well as the accuracy of optical image stabilization. The inner and outer in the present application are relative to the optical axis of the optical lens 2. The direction close to the optical axis is called inner, and the direction far away from the optical axis is called outer.

[0145] Specifically, the focusing function has certain requirements on focusing speed and focusing accuracy. The key factor to achieve a better focusing effect is to quickly and accurately adjust the position of the lens to achieve a clear image. The inner carrier 30 for moving during automatic focusing is arranged in the outer frame 20 for moving during optical anti-shake. During automatic focusing, only the inner carrier 30 needs to be moved to drive the optical lens 2 to move, which makes the first driving assembly 40 for automatic focusing need to drive a relatively small weight of components, so that the first driving assembly 40 for automatic focusing can quickly adjust the position of the optical lens 2, and correspondingly, the optical lens 2 can respond more quickly to the driving of the first driving assembly 40 for automatic focusing, thereby achieving fast focusing.

[0146] The first driving assembly 40 for automatic focusing needs to drive a relatively small weight of components, which means that the first driving assembly 40 for automatic focusing needs to drive a relatively small weight of components compared with the second driving assembly 50 for optical anti-shake. Specifically, during automatic focusing, only the inner carrier 30 needs to be moved to drive the optical lens 2 to move; during optical anti-shake, the second driving assembly 50 needs to drive the outer frame 20, the inner carrier 30 and the first driving assembly 40 to drive the optical lens 2 to move. In other words, the first driving assembly 40 for automatic focusing needs to drive components mainly including the inner carrier 30 and the optical lens 2; the second driving assembly 50 for optical anti-shake needs to drive components including not only the inner carrier 30 and the optical lens 2, but also the outer frame 20 and the first driving assembly 40. Therefore, the weight of the components driven by the first driving assembly 40 for automatic focusing is obviously smaller than the weight of the components driven by the second driving assembly 50 for optical anti-shake.

[0147] Further, the focusing movement stroke of the optical lens 2 is relatively large, and the first driving assembly 40 for automatic focusing only needs to move the inner carrier 30 to drive the optical lens 2 to move, which helps to achieve a longer movement stroke of the optical lens 2. Further, benefiting from the relatively small weight of the components driven by the first driving assembly 40, the first driving assembly 40 can more accurately control the movement of the optical lens 2, which helps to improve the focusing accuracy.

[0148] The second driving assembly 50 for optical image stabilization can be designed to be arranged around the outer periphery of the outer frame 20, which makes the arrangement of the second driving assembly 50 for optical image stabilization more flexible. Since the anti-shake movement stroke is smaller than the focusing movement stroke, the second driving assembly 50 for optical image stabilization can more easily control the movement of the optical lens 2, which helps to improve the optical image stabilization precision and reduce the over-compensation or under-compensation.

[0149] In the embodiments of the present application, the specific forms and structures of the outer housing 10, the outer frame 20 and the inner carrier 30 are designed according to requirements and are not limited by the present application.

[0150] In an embodiment of the present application, as shown in FIGS. 2, 3, 4, 13 and 14, the outer housing 10 includes a base 11 and a cover 12, wherein the cover 12 and the base 11 are buckled to each other to form a receiving cavity 1001 between the base 11 and the cover 12. The base 11 and the cover 12 can be fixed by glue between them.

[0151] Correspondingly, more specifically, in this embodiment, the outer frame 20 is configured to move relative to the base 11 along the first direction D1 and the second direction D2 and drive the inner carrier 30 to move along the first direction D1 and the second direction D2. The second driving assembly 50 is configured to drive the outer frame 20 to move relative to the base 11 along the first direction D1 and the second direction D2, and drive the inner carrier 30 and the optical lens 2 to move along the first direction D1 and the second direction D2 through the outer frame 20 to perform optical image stabilization.

[0152] In this embodiment, the base 11 includes a base bottom wall 111 and a base peripheral wall 112, wherein the base peripheral wall 112 extends upward from the base bottom wall 111. The base peripheral wall 112 includes a base first side wall 1121, a base second side wall 1122, a base third side wall 1123 and a base fourth side wall 1124. The base first side wall 1121 and the base third side wall 1123 are opposite to each other in the first direction D1. The base second side wall 1122 and the base fourth side wall 1124 are opposite to each other in the second direction D2. The base 11 has a base through hole 1101 which penetrates the base 11 in the optical axis direction D.

[0153] The cover 12 includes a cover top wall 121 and a cover peripheral wall 122, wherein the cover peripheral wall 122 extends downward from the cover top wall 121. The cover 12 has a cover through hole 1201 which penetrates the cover 12 in the optical axis direction D.

[0154] It should be appreciated that the top cover 12 can also not be provided with the top cover peripheral wall 122, but only provided with the top cover top wall 121. When the top cover top wall 121 covers the base peripheral wall 112, the accommodation cavity 1001 is formed by the base 11 and the top cover 12.

[0155] The outer frame 20 is movably accommodated in the accommodation cavity 1001 of the outer housing 10. More specifically, the outer frame 20 is movably arranged in the base 11.

[0156] As shown in FIGS. 4-7 and 15-21, the outer frame 20 includes a first frame side wall 21, a second frame side wall 22, a third frame side wall 23, and a fourth frame side wall 24. The first frame side wall 21 and the third frame side wall 23 are opposite each other in the first direction D1, and the second frame side wall 22 and the fourth frame side wall 24 are opposite each other in the second direction D2. The outer frame 20 has a frame through slot 201 extending through the outer frame 20 in the optical axis direction D. The outer frame 20 has a frame upper surface 202 and a frame lower surface 203. The frame upper surface 202 and the frame lower surface 203 are opposite each other in the optical axis direction D.

[0157] The frame upper surface 202 includes a first frame upper side, a second frame upper side, a third frame upper side, and a fourth frame upper side. The first frame upper side and the third frame upper side are opposite each other in the first direction D1, and the second frame upper side and the fourth frame upper side are opposite each other in the second direction D2. The first frame upper side and the second frame upper side meet to form a first frame upper corner portion, the second frame upper side and the third frame upper side meet to form a second frame upper corner portion, the third frame upper side and the fourth frame upper side meet to form a third frame upper corner portion, and the fourth frame upper side and the first frame upper side meet to form a fourth frame upper corner portion.

[0158] The frame lower surface 203 includes a first frame lower side, a second frame lower side, a third frame lower side, and a fourth frame lower side. The first frame lower side and the third frame lower side are opposite each other in the first direction D1, and the second frame lower side and the fourth frame lower side are opposite each other in the second direction D2. The first frame lower side and the second frame lower side meet to form a first frame lower corner portion, the second frame lower side and the third frame lower side meet to form a second frame lower corner portion, the third frame lower side and the fourth frame lower side meet to form a third frame lower corner portion, and the fourth frame lower side and the first frame lower side meet to form a fourth frame lower corner portion.

[0159] The inner carrier 30 is movably accommodated in the frame through slot 201 of the outer frame 20.

[0160] The inner carrier 30 comprises a carrier first side wall 31, a carrier second side wall 32, a carrier third side wall 33 and a carrier fourth side wall 34. The carrier first side wall 31 and the carrier third side wall 33 are opposite in the first direction D1, and the carrier second side wall 32 and the carrier fourth side wall 34 are opposite in the second direction D2. The inner carrier 30 has a carrier through hole 301. The carrier through hole 301 penetrates the inner carrier 30 in the optical axis direction D. The inner carrier 30 has a carrier upper surface 302 and a carrier lower surface 303. The carrier upper surface 302 and the carrier lower surface 303 are opposite in the optical axis direction D.

[0161] The base first side wall 1121, the frame first side wall 21 and the carrier first side wall 31 are on the same side of the driving device 1 for the camera module 100 and opposite in the first direction D1; the base second side wall 1122, the frame second side wall 22 and the carrier second side wall 32 are on the same side of the driving device 1 for the camera module 100 and opposite in the second direction D2; the base third side wall 1123, the frame third side wall 23 and the carrier third side wall 33 are on the same side of the driving device 1 for the camera module 100 and opposite in the first direction D1; the base fourth side wall 1124, the frame fourth side wall 24 and the carrier fourth side wall 34 are on the same side of the driving device 1 for the camera module 100 and opposite in the second direction D2.

[0162] The carrier upper surface 302 comprises a carrier first upper side, a carrier second upper side, a carrier third upper side and a carrier fourth upper side. The carrier first upper side and the carrier third upper side are opposite in the first direction D1. The carrier second upper side and the carrier fourth upper side are opposite in the second direction D2. The carrier first upper side and the carrier second upper side form a carrier first upper corner portion; the carrier second upper side and the carrier third upper side form a carrier second upper corner portion; the carrier third upper side and the carrier fourth upper side form a carrier third upper corner portion; and the carrier fourth upper side and the carrier first upper side form a carrier fourth upper corner portion.

[0163] In the embodiments shown in Figures 1 to 11 of the present application, the driving device 1 for the camera module 100 further comprises a support 80. The support 80 is located on the outer frame 20. The support 80 has a support through hole 801. The support through hole 801 penetrates the support 80 in the optical axis direction D.

[0164] The driving device 1 for the camera module 100 has a lens mounting cavity 101 which penetrates the driving device 1 for the camera module 100 in the optical axis direction D. The optical lens 2 is mounted in the lens mounting cavity 101 of the driving device 1 for the camera module 100.

[0165] In the embodiment of the present application, the top cover through hole 1201, the support through hole 801, the carrier through hole 301 and the base through hole 1101 jointly form the lens mounting cavity 101. The inner diameters of the top cover through hole 1201, the support through hole 801, the carrier through hole 301 and the base through hole 1101 are all greater than or equal to the outer diameter of the optical lens 2. Accordingly, in theory, when the optical lens 2 is driven, the bottom surface of the optical lens 2 can be flush with the bottom surface of the base 11, or even lower than the bottom surface of the base 11.

[0166] It is worth mentioning that in the present application, the center of the lens mounting cavity 101 of the driving device 1 for the camera module 100 can be designed to be located on the optical axis of the optical lens 2 when the optical lens 2 is mounted in the driving device 1 for the camera module 100.

[0167] In an embodiment of the present application, the center of the lens mounting cavity 101 is designed to be consistent with the center of the driving device 1 for the camera module 100, or the center of the lens mounting cavity 101 is designed to be located on the longitudinal center axis of the driving device 1 for the camera module 100, so that the optical lens 2 is located in the middle of the driving device 1 for the camera module 100, thereby reducing the instability caused by excessive deviation of the center of the optical lens 2. The longitudinal center axis of the driving device 1 for the camera module 100 extends in the same direction as the optical axis direction D, and the center of the driving device 1 for the camera module 100 is located on the longitudinal center axis of the driving device 1 for the camera module 100. It should be understood that there is an error when assembling components, and an error of less than 1 mm is allowed. Accordingly, here, the center of the lens mounting cavity 101 being consistent with the center of the driving device 1 for the camera module 100 means that the distance between the center of the lens mounting cavity 101 and the center of the driving device 1 for the camera module 100 in the direction perpendicular to the optical axis direction D is greater than or equal to 0 and less than or equal to 1 mm. Accordingly, the distance between the center of the optical lens 2 and the center of the driving device 1 for the camera module 100 in the direction perpendicular to the optical axis direction D is greater than or equal to 0 and less than or equal to 1 mm; or the distance between the center of the driving device 1 for the camera module 100 and the optical axis in the direction perpendicular to the optical axis direction D is greater than or equal to 0 and less than or equal to 1 mm.

[0168] In an embodiment of the present application, the center of the top cover through hole 1201, the center of the support through hole 801, the center of the frame through slot 201, the center of the carrier through hole 301, and the center of the base through hole 1101 are all located on the optical axis of the optical lens 2 to improve the stability of the driving device 1 for the camera module 100. In the top view of the driving device 1 for the camera module 100 installed with the optical lens 2, the center of the driving device 1 for the camera module 100 coincides with the center of the optical lens 2. The design that the center of the driving device 1 for the camera module 100 is located on the optical axis of the optical lens 2 helps the driving device 1 for the camera module 100 to keep position balance and driving balance after the optical lens 2 is installed, and reduces instability caused by excessive deviation of the center of the optical lens 2.

[0169] In the present application, the center and the barycenter of the optical lens 2 can be designed to be located on the optical axis. When the optical lens 2 is installed in the driving device 1 for the camera module 100, the barycenter of the driving device 1 for the camera module 100 is not located on the optical axis of the optical lens 2. Specifically, because the outer frame 20 and the inner carrier 30 need to install driving components, the barycenter of the outer frame 20 and the inner carrier 30 deviates to the side where the driving components are arranged, so that the barycenter of the driving device 1 for the camera module 100 has a certain distance from the optical axis of the optical lens 2.

[0170] The first driving component 40 is installed on the outer side of the inner carrier 30. Specifically, the first driving component 40 is installed between the inner carrier 30 and the outer frame 20 or between the inner carrier 30 and the base 11. The second driving component 50 is installed on the outer side of the outer frame 20. Specifically, the second driving component 50 is installed between the outer frame 20 and the base 11.

[0171] More specifically, the first driving assembly 40 is mounted between the carrier one side wall 31 of the inner carrier 30 and the frame one side wall 21 of the outer frame 20, or between the carrier one side wall 31 of the inner carrier 30 and the base one side wall 1121 of the base 11. The second driving assembly 50 includes a unidirectional driving assembly 51 and a bidirectional driving assembly 52. The unidirectional driving assembly 51 is configured to drive the outer frame 20 to move relative to the base 11 along the first direction D1, and drive the inner carrier 30 and the optical lens 2 to move along the first direction D1 through the outer frame 20. The bidirectional driving assembly 52 is configured to drive the outer frame 20 to move relative to the base 11 along the second direction D2, and drive the inner carrier 30 and the optical lens 2 to move along the second direction D2 through the outer frame 20. The unidirectional driving assembly 51 is mounted between the frame three side wall 23 of the outer frame 20 and the base three side wall 1123 of the base 11. The bidirectional driving assembly 52 is mounted between the frame two side wall 22 of the outer frame 20 and the base two side wall 1122 of the base 11.

[0172] In the embodiments of the present application, the driving of the inner carrier 30 and the outer frame 20 is achieved by the cooperation of magnets and coils. Accordingly, the first driving assembly 40 includes a first coil 41 and a first magnet 42. The unidirectional driving assembly 51 includes a second coil 511 and a second magnet 512. The bidirectional driving assembly 52 includes a third coil 521 and a third magnet 522.

[0173] It is worth mentioning that, in the present application, as shown in FIG. 16, the magnets and coils of the driving assembly are arranged in the transverse direction, which can reduce the height dimension of the driving device 1 for the camera module 100 to a certain extent compared with the arrangement of the magnets and coils in the optical axis direction D. The transverse direction refers to the direction perpendicular to the optical axis direction D. In the present application, the transverse direction is consistent with the horizontal direction.

[0174] Specifically, the first driving assembly 40 is of a moving magnet type structure. The moving magnet type structure refers to that under the interaction of the coil and the magnet, the magnet moves, and in turn drives the component fixed with the magnet to move. The first coil 41 and the first magnet 42 are arranged on the first side of the inner carrier 30, i.e., the side where the carrier one side wall 31 is located, and are opposite to the first coil 41 in the first direction D1, and are located between the inner carrier 30 and the outer frame 20. More specifically, the first magnet 42 is mounted on the outer surface of the carrier one side wall 31. The first coil 41 is mounted on the inner surface of the frame one side wall 21.

[0175] In one variant of the present application, the first magnet 42 is mounted on the outer surface of the carrier side wall 31, and the first coil 41 is mounted on the inner surface of the base side wall 1121.

[0176] Further, the first magnet 42 can be designed to be at least partially embedded in the carrier side wall 31 of the inner carrier 30, and / or the first coil 41 can be designed to be at least partially embedded in the frame side wall 21 of the outer frame 20, so as to reduce the lateral space occupied by the first driving assembly 40, thereby reducing the lateral size of the driving device 1 for the camera module 100, and further reducing the lateral size of the camera module 100.

[0177] In one example of the present application, the inner carrier 30 has a carrier recess 304 formed recessed on the outer surface of the carrier side wall 31. The first magnet 42 is at least partially embedded in the carrier recess 304. The outer frame 20 has a frame recess 204 formed recessed on the inner surface of the frame side wall 21. The first coil 41 is at least partially embedded in the frame recess 204.

[0178] In the embodiments shown in FIGS. 12-24 of the present application, the driving device 1 for the camera module 100 further comprises a frame circuit board 25 arranged on the outer side of the outer frame 20; the first coil 41 is fixed on the inner side of the frame circuit board 25 and electrically connected to the frame circuit board 25. Specifically, in the embodiments shown in FIGS. 12-24 of the present application, the frame circuit board 25 is arranged on the frame side wall 21 of the outer frame 20 and the frame four side wall 24 adjacent to the frame side wall 21; the first coil 41 is at least partially embedded in the frame recess 204 of the outer frame 20, and the frame recess 204 is a through slot.

[0179] The one-direction driving assembly 51 is of a moving magnet type. The second coil 511 and the second magnet 512 are arranged on the third side of the outer frame 20, i.e., the frame three side wall 23, and are opposite to each other in the first direction D1, and are located between the outer frame 20 and the base 11. Specifically, the second magnet 512 is mounted on the outer surface of the frame three side wall 23. The second coil 511 is mounted on the inner surface of the base three side wall 1123.

[0180] More specifically, the second magnet 512 can be designed to be at least partially embedded in the frame three side wall 23 of the outer frame 20, and / or the second coil 511 can be designed to be at least partially embedded in the base three side wall 1123 of the base 11, so as to reduce the transverse space occupied by the one-way driving assembly 51, thereby reducing the transverse size of the driving device 1 for the camera module 100, and further reducing the transverse size of the camera module 100.

[0181] In one example of the present application, as shown in FIG. 7, the frame three side wall 23 has a frame two recess 205 formed recessed on the outer surface of the frame three side wall 23. The second magnet 512 is at least partially embedded in the frame two recess 205. As shown in FIG. 4, the base 11 has a base one recess 1102 formed recessed on the inner surface of the base three side wall 1123. The second coil 511 is at least partially embedded in the base one recess 1102.

[0182] The two-way driving assembly 52 is of a moving magnet type. The third coil 521 and the third magnet 522 are arranged on the second side of the outer frame 20, i.e., the side where the frame two side wall 22 is located, and are opposite to each other in the second direction D2, and are located between the outer frame 20 and the base 11. Specifically, the third magnet 522 is mounted on the outer surface of the frame two side wall 22. The third coil 521 is mounted on the inner surface of the base two side wall 1122.

[0183] More specifically, the third magnet 522 can be designed to be at least partially embedded in the frame two side wall 22 of the outer frame 20, and / or the third coil 521 can be designed to be at least partially embedded in the base two side wall 1122 of the base 11, so as to reduce the transverse space occupied by the two-way driving assembly 52, thereby reducing the transverse size of the driving device 1 for the camera module 100, and further reducing the transverse size of the camera module 100.

[0184] In one example of the present application, as shown in FIG. 7, the frame two side wall 22 has a frame three recess 206 formed recessed on the outer surface of the frame two side wall 22. The third magnet 522 is at least partially embedded in the frame three recess 206. As shown in FIG. 4, the base 11 has a base two recess 1103 formed recessed on the inner surface of the base two side wall 1122. The third coil 521 is at least partially embedded in the base two recess 1103.

[0185] As described above, in the present application, the first driving assembly 40, the first driving assembly 51 and the second driving assembly 52 are all of the moving magnet type, and correspondingly, the first magnet 42 is mounted on the inner carrier 30; the second magnet 512 and the third magnet 522 are mounted on the outer frame 20; the first coil 41 is mounted on the outer frame 20 or the base 11; the second coil 511 and the third coil 521 are mounted on the base 11; such an arrangement facilitates subsequent wiring of the first coil 41, the second coil 511 and the third coil 521, and realizes electrical conduction of the first coil 41, the second coil 511 and the third coil 521. Specifically, on the one hand, the mounting carrier of the first coil 41 (i.e., the outer frame 20 or the base 11) is similar to or the same as the mounting carrier of the second coil 511 and the third coil 521 (i.e., the base 11), so that the first coil 41, the second coil 511 and the third coil 521 are more convenient to wire. On the other hand, the outer frame 20 and the base 11 are relatively close to the outer side of the driving device 1 for the camera module 100 relative to the inner carrier 30, facilitating the outward extension of the conductive member electrically connected to the first coil 41, the second coil 511 and the third coil 521.

[0186] It should be understood that the first coil 41 and the first magnet 42 can be interchanged in position; the second coil 511 and the second magnet 512 can be interchanged in position; and the third coil 521 and the third magnet 522 can be interchanged in position.

[0187] In the present application, the first magnet 42 and the first coil 41 are used solely for automatic focusing drive and are not used for optical image stabilization; the second magnet 512 and the second coil 511, and the third magnet 522 and the third coil 521 are used solely for optical image stabilization and are not used for automatic focusing; in this way, the first magnet 42, the second magnet 512 and the third magnet 522 do not interfere with each other; and the first coil 41, the second coil 511 and the third coil 521 do not interfere with each other.

[0188] In the present application, the driving device 1 for the camera module 100 is not provided with a driving assembly on at least one side, and correspondingly, the camera module 100 is not provided with a driving assembly on at least one side; in this way, when the camera module 100 is mounted on a terminal mobile device, if the camera module 100 is provided with other camera modules, the side of the camera module 100 of the present application on which no driving assembly is provided can be adjacent to the other camera modules, so as to avoid magnetic interference between multiple camera modules.

[0189] In the embodiments of the present application, the fourth side of the driving device 1 for the camera module 100 is not provided with a driving assembly. Accordingly, when the camera module 100 is installed in a terminal mobile device, if the camera module 100 is provided with other camera modules, the fourth side of the camera module 100 of the present application can be adjacent to the other camera modules. The fourth side of the driving device 1 for the camera module 100 is consistent with the fourth side of the camera module 100, and is consistent with the side where the carrier four side walls 34, the frame four side walls 24 and the base four side walls 1124 are located.

[0190] In addition, in the present application, the first driving assembly 40, the one-way driving assembly 51 and the two-way driving assembly 52 are arranged on different sides of the driving device 1 for the camera module 100, i.e., the first side, the third side and the second side. On the one hand, this can avoid mutual interference between the first driving assembly 40, the one-way driving assembly 51 and the two-way driving assembly 52 to some extent, and help to ensure the stability of each driving; on the other hand, this can increase the space for arranging each magnet, and the overall magnetic field is uniformly distributed, which helps to improve the anti-shake and focusing effect.

[0191] Specifically, the second magnet 512 and the third magnet 522 for realizing anti-shake driving and the first magnet 42 for realizing focusing driving are arranged on different sides of the driving device 1 for the camera module 100, which not only can avoid magnetic interference, but also can provide sufficient arrangement space for each magnet, i.e., the first magnet 42, the second magnet 512 and the third magnet 522, can increase the magnetic field strength, and the overall magnetic field of the first magnet 42, the second magnet 512 and the third magnet 522 is uniformly distributed, which helps to improve the anti-shake and focusing effect.

[0192] It is worth mentioning that, in an embodiment of the present application, the lower surface of the first driving assembly 40 for driving the optical lens 2 to perform automatic focusing of the driving device 1 for the camera module 100 is at a relatively low height. Specifically, the bottom surface of the first magnet 42 of the first driving assembly 40 is lower than the bottom surface of the second magnet 512 and / or the bottom surface of the third magnet 522 of the second driving assembly 50; the bottom surface of the first coil 41 of the first driving assembly 40 is lower than the bottom surface of the second coil 511 and / or the bottom surface of the third coil 521 of the second driving assembly 50. In this way, not only can the height dimension of the driving device 1 for the camera module 100 be reduced, thereby reducing the height dimension of the camera module 100, but also the focusing moving stroke can be increased, thereby improving the focusing function of the camera module 100.

[0193] It should be appreciated that the larger the size of the first magnet 42 and the first coil 41 in the height direction of the driving device 1 for the camera module 100, the larger the driving force and the driving stroke that the first driving assembly 40 can provide. However, increasing the size of the first magnet 42 and the first coil 41 in the height direction of the driving device 1 for the camera module 100 can result in an increase in the height of the driving device 1 for the camera module 100. In the present application, the size of the first magnet 42 and the first coil 41 in the height direction of the driving device 1 for the camera module 100 is increased by extending the first magnet 42 and the first coil 41 downward to increase the focusing stroke and thus improve the focusing function of the camera module 100. Further, the height of the driving device 1 for the camera module 100 can also be avoided from increasing. Moving the first magnet 42 and the first coil 41 downward as a whole can also reduce the height of the driving device 1 for the camera module 100.

[0194] Correspondingly, extending the first magnet 42 and the first coil 41 downward or moving the first magnet 42 and the first coil 41 downward as a whole finally results in that the bottom surface of the first magnet 42 of the first driving assembly 40 is lower than the bottom surface of the second magnet 512 and / or the bottom surface of the third magnet 522 of the second driving assembly 50; and the bottom surface of the first coil 41 of the first driving assembly 40 is lower than the bottom surface of the second coil 511 and / or the bottom surface of the third coil 521 of the second driving assembly 50.

[0195] In an embodiment of the present application, as shown in FIG. 2 and FIG. 13, the driving device 1 for the camera module 100 further comprises at least one magnetic yoke 91 for increasing the magnetic field strength and preventing magnetic leakage. The magnetic yoke 91 is located on the side of each magnet away from the coil.

[0196] In the present application, the driving device 1 for the camera module 100 comprises three magnetic yokes 91, which are respectively a first magnetic yoke 911, a second magnetic yoke 912 and a third magnetic yoke 913. The first magnetic yoke 911 is opposite to the first magnet 42 in the first direction and is located on the side of the first magnet 42 away from the first coil 41, so as to increase the magnetic field strength of the focusing magnet, i.e. the first magnet 42, and reduce magnetic leakage. The second magnetic yoke 912 is opposite to the second magnet 512 in the first direction and is located on the side of the second magnet 512 away from the second coil 511, so as to increase the magnetic field strength of the anti-shake magnet, i.e. the second magnet 512, and reduce magnetic leakage. The third magnetic yoke 913 is opposite to the third magnet 522 in the second direction and is located on the side of the third magnet 522 away from the third coil 521, so as to increase the magnetic field strength of the anti-shake magnet, i.e. the third magnet 522, and reduce magnetic leakage.

[0197] Optionally, the first magnetic yoke 911 is embedded in the inner carrier 30, and the second magnetic yoke 912 and the third magnetic yoke 913 are embedded in the outer frame 20. More specifically, the first magnetic yoke 911 is embedded in the carrier side wall 31 of the inner carrier 30, the second magnetic yoke 912 is embedded in the frame side wall 22 of the outer frame 20, and the third magnetic yoke 913 is embedded in the frame side wall 23 of the outer frame 20. It should be understood that the first magnetic yoke 911, the second magnetic yoke 912 and the third magnetic yoke 913 can also be arranged in a non-embedded manner.

[0198] In an embodiment of the present application, as shown in FIGS. 2 and 13, the driving device 1 for the camera module 100 further comprises a magnetic attraction element 92. At least one magnetic attraction element 92 is located on the side of the first coil 41 away from the first magnet 42. The magnetic attraction element 92 has magnetic permeability and can be attracted to the first magnet 42. The attraction force between the magnetic attraction element 92 and the first magnet 42 causes the inner carrier 30 and the outer frame 20 to approach each other, and the inner carrier 30 is supported by the first support assembly 60, which can improve the driving stability and prevent the inner carrier 30 and the outer frame 20 from falling.

[0199] As shown in FIG. 2, the magnetic attraction element 92 can be embedded in the outer frame 20. More specifically, the magnetic attraction element 92 is embedded in the frame side wall 21 of the outer frame 20.

[0200] In another embodiment of the present application, the magnetic member 92 can also be embedded in the base 11, and more particularly, the magnetic member 92 is embedded in the base side wall 1121 of the base 11, such that the magnetic member 92 is horizontally opposite to the first magnet 42. The inner carrier 30 is attracted to the base 11 by the attractive force between the magnetic member 92 and the first magnet 42, and the first support assembly 60 is clamped between the inner carrier 30 and the base side wall 1121 under the attractive force between the magnetic member 92 and the first magnet 42. Of course, the outer frame 20 can be clamped between the inner carrier 30 and the base side wall 1121. It is worth mentioning that, in an embodiment of the present application, the second magnetic yoke 912, the third magnetic yoke 913 and the magnetic member 92 are integrally connected, having an integrated structure. In another embodiment of the present application, the second magnetic yoke 912, the third magnetic yoke 913 and the magnetic member 92 are separately connected, having a separate structure.

[0201] In another embodiment of the present application, the magnetic member 92 can also be embedded in the base 11, and more particularly, the magnetic member 92 is embedded in the base bottom wall 111 of the base 11, such that the magnetic member 92 is vertically opposite to the second magnet 512 and the third magnet 522, respectively. The outer frame 20 is attracted to the base 11 by the attractive force between the magnetic member 92 and the second magnet 512 and the third magnet 522, and the second support assembly 70 is clamped between the outer frame 20 and the base bottom wall 111 under the attractive force between the magnetic member 92 and the second magnet 512 and the third magnet 522.

[0202] In another embodiment of the present application, the magnetic member 92 can also be embedded in the base 11, and more particularly, the magnetic member 92 is embedded in the base bottom wall 111 of the base 11, such that the magnetic member 92 is vertically opposite to the second magnet 512 and the third magnet 522, respectively. The outer frame 20 is attracted to the base 11 by the attractive force between the magnetic member 92 and the second magnet 512 and the third magnet 522, and the second support assembly 70 is clamped between the outer frame 20 and the base bottom wall 111 under the attractive force between the magnetic member 92 and the second magnet 512 and the third magnet 522.

[0203] The magnetic attraction member 92 in the application is defined as a focusing magnetic attraction member 9210 for mutual attraction with the first magnet 41 to make the outer frame 20 and the inner carrier 30 close to each other, and the magnetic attraction member 92 for mutual attraction with the second magnet 512 and / or the third magnet 522 to make the outer frame 20 and the bottom wall 111 of the base close to each other is defined as an anti-shake magnetic attraction member 9220. Accordingly, the magnetic attraction member 92 includes a focusing magnetic attraction member 9210 and an anti-shake magnetic attraction member 9220.

[0204] In an embodiment of the application, as shown in FIG. 20, the driving device 1 for the camera module 100 includes at least one focusing magnetic attraction member 9210. The focusing magnetic attraction member 9210 is located on the side of the first coil 41 away from the first magnet 42. The focusing magnetic attraction member 9210 has magnetic permeability and can be attracted to the first magnet 42. The attractive force between the focusing magnetic attraction member 9210 and the first magnet 42 makes the inner carrier 30 and the outer frame 20 close to each other, the inner carrier 30 is supported by the first support assembly 60, which can improve the driving stability and prevent the inner carrier 30 and the outer frame 20 from falling.

[0205] At least one focusing magnetic attraction member is provided on the outer frame 20. In the embodiment of the outer frame 20 shown in FIGS. 12-24, the frame circuit board 25 is provided, and at least one focusing magnetic attraction member 9210 can be fixed to the frame circuit board 25 and provided on the outer frame 20. The frame circuit board 25 corresponds to the first coil 41 and the first magnet 42 in the first direction D1. Specifically, at least one focusing magnetic attraction member 9210 can be fixed to the outside of the frame circuit board 25. The attractive force between the magnetic attraction member 92 and the first magnet 42 makes the inner carrier 30 adsorbed on the side of the outer frame 20 where the magnetic attraction member 92 is provided.

[0206] In another embodiment of the application, the focusing magnetic attraction member 9210 can also be embedded in the base 11. More specifically, the focusing magnetic attraction member 9210 is embedded in the base side wall 1121 of the base 11, so that the magnetic attraction member 92 and the first magnet 42 are opposite in the horizontal direction. The attractive force between the focusing magnetic attraction member 9210 and the first magnet 42 makes the inner carrier 30 and the base 11 close to each other, the outer frame 20 clamped between the base 11 and the inner carrier 30 and the inner carrier 30 close to each other, and the first support assembly 60 clamped between the inner carrier 30 and the base side wall 1121 under the action of the attractive force between the magnetic attraction member 92 and the first magnet 42.

[0207] In an embodiment of the present application, the driving device 1 for the camera module 100 comprises at least one magnetic attraction member 9220 for anti-vibration. The magnetic attraction member 9220 has magnetic permeability and can be attracted to the second magnet 512 and / or the third magnet 522. The attraction between the magnetic attraction member 9220 and the second magnet 512 and / or the third magnet 522 causes the outer frame 20 to be closer to the base 11, and the outer frame 20 is supported by the second support assembly 70, thereby improving driving stability and preventing the outer frame 20 from falling.

[0208] The at least one magnetic attraction member 9220 for anti-vibration can be embedded in the base 11, and more specifically, the magnetic attraction member 9220 is embedded in the base two side wall 1122 and / or the base three side wall 1123 of the base 11, so that the magnetic attraction member 9220 is opposite to the second magnet 512 and / or the third magnet 522 in the horizontal direction. The attraction between the magnetic attraction member 9220 and the second magnet 512 and / or the third magnet 522 causes the second support assembly 70 to be clamped between the outer frame 20 and the base bottom wall 111.

[0209] In another embodiment of the present application, as shown in FIG. 20, the magnetic attraction member 9220 for anti-vibration is embedded in the base bottom wall 111 of the base 11, so that the magnetic attraction member 9220 is opposite to the second magnet 512 and / or the third magnet 522 in the vertical direction. The attraction between the magnetic attraction member 9220 and the second magnet 512 and / or the third magnet 522 causes the outer frame 20 to be closer to the base 11, and the second support assembly 70 is clamped between the outer frame 20 and the base bottom wall 111 under the action of the attraction between the magnetic attraction member 9220 and the second magnet 512 and / or the third magnet 522.

[0210] In the embodiments shown in FIGS. 12-24 of the present application, the outer frame 20 is provided with a frame circuit board 25, and the at least one magnetic attraction member 92 can be arranged on the outer frame 20 in a manner that the magnetic attraction member 92 is fixed to the frame circuit board 25 and corresponds to the first coil 41 and the first magnet 42 in the first direction D1. Specifically, the magnetic attraction member 92 can be fixed to the outer side of the frame circuit board 25. The attraction between the magnetic attraction member 92 and the first magnet 42 causes the inner carrier 30 to be attracted to the side of the outer frame 20 where the magnetic attraction member 92 is arranged.

[0211] As shown in FIG. 2 and FIG. 13, the driving device 1 for the camera module 100 further comprises a first position sensing element 951, a second position sensing element 952 and a third position sensing element 953. The first position sensing element 951 is adjacent to the first driving assembly 40, and is used to determine the position change of the inner carrier 30; the second position sensing element 952 is adjacent to the one-way driving assembly 51, and is used to determine the position change of the outer frame 20 in the first direction D1; the third position sensing element 953 is adjacent to the two-way driving assembly 52, and is used to determine the position change of the outer frame 20 in the second direction D2.

[0212] In an example of the present application, the first position sensing element 951 is opposite to the first magnet 42, and can be arranged in the first coil 41; the second position sensing element 952 is opposite to the second magnet 512, and can be arranged in the second coil 511; the third position sensing element 953 is opposite to the third magnet 522, and can be arranged in the third coil 521.

[0213] The first position sensing element 951, the second position sensing element 952 and the third position sensing element 953 can be a Hall sensor, an inductive encoder chip (i.e. an IC chip), or an inductive encoder chip cooperating with a capacitor, or a TMR.

[0214] In the embodiments of the present application, the first support assembly 60 and the second support assembly 70 provide guiding and supporting actions for the movement of the inner carrier 30 and the outer frame 20, so that the inner carrier 30 and the outer frame 20 can move more stably.

[0215] In an embodiment of the present application, the first support assembly 60 is a fixed support assembly, i.e. is fixedly installed inside the driving device 1 for the camera module 100, and does not move when the inner carrier 30 moves. Correspondingly, the first support assembly 60 fixedly supports the movement of the inner carrier 30 along the optical axis direction D.

[0216] The first support assembly 60 can be arranged on the side where the first driving assembly 40 is located. In this way, the action point of the force generated by the first driving assembly 40 is closer to the first support assembly 60, thereby reducing the overturning moment generated during focusing. The inner carrier 30 generates a smaller tilting or offset moment, so that the inner carrier 30 is not easy to tilt during focusing, thereby ensuring the sharpness of the image and the accuracy of focusing. Moreover, since the tilting of the inner carrier 30 is reduced, the first driving assembly 40 can respond to the focusing instruction more quickly, thereby achieving fast and accurate focusing.

[0217] Correspondingly, in an embodiment of the present application, the first driving assembly 40 and the first supporting assembly 60 are both arranged on the first side of the inner carrier 30, i.e. on the side of the carrier side wall 31.

[0218] Specifically, in one example, as shown in FIG. 4 and FIG. 15, the first supporting assembly 60 is arranged between the inner carrier 30 and the outer frame 20, and between the carrier side wall 31 and the frame side wall 21. Correspondingly, the first supporting assembly 60 is arranged on the inner side of the outer frame 20. A longitudinal guide groove 230 is arranged between the inner carrier 30 and the outer frame 20, and extends along the optical axis direction D. The first supporting assembly 60 can be tightly fitted with the longitudinal guide groove 230, i.e. closely fitted, or loosely fitted with the longitudinal guide groove 230, i.e. fitted with a certain movability.

[0219] Specifically, in another example, the first supporting assembly 60 is arranged between the inner carrier 30 and the bottom seat peripheral wall 112 of the bottom seat, e.g. between the carrier side wall 31 and the bottom seat side wall 1121. Correspondingly, the first supporting assembly 60 is arranged on the inner side of the bottom seat 11. A longitudinal guide groove 230 is arranged between the inner carrier 30 and the bottom seat 11, and extends along the optical axis direction D. The first supporting assembly 60 can be tightly fitted with the longitudinal guide groove 230, i.e. closely fitted, or loosely fitted with the longitudinal guide groove 230, i.e. fitted with a certain movability.

[0220] In an embodiment of the present application, the first supporting assembly 60 is implemented as a guide rod 610. Correspondingly, the first supporting assembly 60 includes at least one guide rod 610, and the length extension direction of the guide rod 610 is consistent with the optical axis direction D. The length of the guide rod 610 is greater than the moving stroke of the inner carrier 30 along the optical axis direction D, so that the inner carrier 30 can be supported within the moving stroke. Further, the guide rod 610 has good linearity, which can further avoid the generation of the inner carrier 30 tilting.

[0221] In the embodiment shown in FIGS. 1-11 of the present application, the guide rod 610 is clamped between the outer frame 20 and the support 80 in the optical axis direction D. Specifically, the support 80 includes a support lower portion 81 and a support upper portion 82, the support upper portion 82 protruding upward relative to the support lower portion 81, such that the support lower portion 81 and the support upper portion 82 form a stepped structure with a height difference. The support upper portion 82 extends integrally from the support lower portion 81. The support lower portion 81 is fixed to the outer frame 20, such that the support 80 as a whole is fixed above the inner carrier 30 and the outer frame 20. The upper end of the guide rod 610 abuts against the support upper portion 82 of the support 80. The support 80 is in the form of a sheet. The support 80 can be implemented as a metal sheet.

[0222] The outer frame 20 has at least one frame protrusion 207 extending inward from the side wall of the outer frame 20, i.e., toward the frame through slot 201. In the embodiment shown in FIGS. 1-11 of the present application, the lower end of the guide rod 610 abuts against the frame protrusion 207, and the upper end of the guide rod 610 abuts against the support 80. Further, the lower end of the guide rod 610 is fitted into the frame protrusion 207 to extend inward of the outer frame 20, increasing the fixing stability. Accordingly, the guide rod 610 has a lower protrusion at the lower end thereof, and the lower protrusion of the guide rod 610 is embedded in the frame protrusion 207.

[0223] In the embodiment shown in FIGS. 12-24 of the present application, the driving device 1 for the camera module 100 further includes at least one guide rod mounting insert 26, which is embedded in the frame protrusion 207 at the bottom of the outer frame 20 or is formed in the outer frame 20 as the frame protrusion 207. The lower end of the guide rod 610 can be fixed to the guide rod mounting insert 26 by welding or other means, and thus is fixed to the outer frame 20. Further, glue can be provided between the frame protrusion 207 and the guide rod 610 to reinforce the connection between the guide rod 610 and the outer frame 20.

[0224] In the embodiments shown in Figs. 1-11 and Figs. 12-24, the frame protrusion 207 extends inwardly from the bottom of the outer frame 20. The base 11 has a base bottom groove 1104 formed recessed on the inner surface of the base bottom wall 111, and the frame protrusion 207 is fitted into the base bottom groove 1104, so that the frame protrusion 207 is accommodated in the base bottom groove 1104, which facilitates positioning of the guide rod 610 while avoiding affecting the movement of the outer frame 20.

[0225] In the embodiments shown in Figs. 1-11 and Figs. 12-24, the first support assembly 60 includes two guide rods 610, which are a first guide rod 61 and a second guide rod 62. Specifically, the first guide rod 61 and the second guide rod 62 are arranged on the first side of the inner carrier 30 and opposite each other in the second direction D2, located on both sides of the first magnet 42. More specifically, the first guide rod 61 is arranged between the carrier side wall 31 and the frame side wall 21 and located close to the carrier fourth side wall 34; the second guide rod 62 is arranged between the carrier side wall 31 and the frame side wall 21 and located close to the carrier second side wall 32. It should be understood that the positions of the first guide rod 61 and the second guide rod 62 can be interchanged, i.e., the first guide rod 61 can be located close to the carrier second side wall 32 and the second guide rod 62 can be located close to the carrier fourth side wall 34. The action point of the force generated by the first drive assembly 40 is closer to the first guide rod 61 and the second guide rod 62, thereby reducing the overturning moment generated during focusing.

[0226] The length extension direction of the first guide rod 61 is consistent with the optical axis direction D; the length extension direction of the second guide rod 62 is consistent with the optical axis direction D. The length of the first guide rod 61 is greater than the movement stroke of the inner carrier 30 in the optical axis direction D, and the length of the second guide rod 62 is greater than the movement stroke of the inner carrier 30 in the optical axis direction D, so that the inner carrier 30 can be supported within the movement stroke.

[0227] Correspondingly, in the embodiments shown in Figs. 1-11, in the optical axis direction D, the first guide rod 61 and the second guide rod 62 are clamped between the outer frame 20 and the support 80.

[0228] Specifically, the outer frame 20 has a first frame protruding part 2071 and a second frame protruding part 2072, which respectively extend inwardly from the frame side wall 21, i.e., toward the frame through slot 201. The base 11 has a first base bottom recess 11041 and a second base bottom recess 11042. The first base bottom recess 11041 and the second base bottom recess 11042 are recessedly formed on the inner surface of the base bottom wall 111. The first frame protruding part 2071 and the second frame protruding part 2072 are respectively embedded in the first base bottom recess 11041 and the second base bottom recess 11042.

[0229] In the embodiment shown in FIGS. 1-11 of the present application, the lower end of the first guide rod 61 abuts against the first frame protruding part 2071, and the lower end of the second guide rod 62 abuts against the second frame protruding part 2072. The upper end of the first guide rod 61 and the upper end of the second guide rod 62 abut against the support 80. Specifically, the upper end of the first guide rod 61 and the upper end of the second guide rod 62 abut against the support high part 82 of the support 80.

[0230] Further, the lower end of the first guide rod 61 is fitted into the first frame protruding part 2071, and the lower end of the second guide rod 62 is fitted into the second frame protruding part 2072, so as to be deeply embedded in the outer frame 20, thereby increasing the fixing stability. Correspondingly, the first guide rod 61 has a first lower protrusion at the lower end thereof, and the first lower protrusion of the first guide rod 61 is embedded in the first frame protruding part 2071. The second guide rod 62 has a second lower protrusion at the lower end thereof, and the second lower protrusion of the second guide rod 62 is embedded in the second frame protruding part 2072.

[0231] In one example of the present application, the guide rod 610 is integrally formed with the outer frame 20. For example, the guide rod 610 is embedded in the outer frame 20 during the injection molding process of the outer frame 20. In this way, the guide rod 610 can be directly fixed to the outer frame 20, which not only helps to ensure the linearity of the guide rod 610, but also reduces the height of the guide rod 610, thereby reducing the height of the driving device 1. Further, the support 80 can be cancelled to further reduce the height of the driving device 1.

[0232] Specifically, the positions of the first guide rod 61 and the second guide rod 62 in the outer frame 20 can be determined first, and then the first guide rod 61, the second guide rod 62 and the outer frame 20 can be integrally injection molded by using an insert injection molding process. Of course, a connecting structure can be arranged between the first guide rod 61 and the second guide rod 62, and then the first guide rod 61, the second guide rod 62 and the outer frame 20 can be integrally injection molded by using an insert injection molding process. In this way, the parallelism between the first guide rod 61 and the second guide rod 62 can be improved. The inner carrier 30 and the outer frame 20 are provided with a first longitudinal guide groove 2301 and a second longitudinal guide groove 2302. The first longitudinal guide groove 2301 and the second longitudinal guide groove 2302 both extend along the optical axis direction D. The first guide rod 61 is at least partially located in the first longitudinal guide groove 2301, and the second guide rod 62 is at least partially located in the second longitudinal guide groove 2302, so that the inner carrier 30 is adapted to stably move along the first guide rod 61 and the second guide rod 62 along the optical axis direction D.

[0233] In the embodiment shown in FIGS. 12-24 of the present application, the driving device 1 for the camera module 100 further comprises two guide rod mounting inserts 26, which are a first guide rod mounting insert 261 and a second guide rod mounting insert 262 respectively. The first guide rod mounting insert 261 is embedded in the first frame protruding portion 2071; the second guide rod mounting insert 262 is embedded in the second frame protruding portion 2072. The first guide rod 61 can be fixed to the first guide rod mounting insert 261 by welding; the second guide rod 62 can be fixed to the second guide rod mounting insert 262 by welding, and then fixed to the outer frame 20. Further, glue can be arranged between the first frame protruding portion 2071 and the first guide rod 61, and glue can be arranged between the second frame protruding portion 2072 and the second guide rod 62, so as to reinforce the connection between the first guide rod 61 and the outer frame 20 and the connection between the second guide rod 62 and the outer frame 20.

[0234] The first guide rod 61 is tightly fitted with the first longitudinal guide groove 2301, and the second guide rod 62 is loosely fitted with the second longitudinal guide groove 2302. It can be understood that by tightly fitting the first guide rod 61 with the first longitudinal guide groove 2301 and loosely fitting the second guide rod 62 with the second longitudinal guide groove 2302, the assembly difficulty between the inner carrier 30 and the outer frame 20 can be reduced.

[0235] Specifically, the first longitudinal guide slot 2301 comprises a first carrier longitudinal half guide slot 23011 and a first frame longitudinal half guide slot 23012. The first carrier longitudinal half guide slot 23011 and the first frame longitudinal half guide slot 23012 are opposite in the first direction D1. The first carrier longitudinal half guide slot 23011 is formed on the outer surface of the carrier side wall 31 of the inner carrier 30; the first frame longitudinal half guide slot 23012 is formed on the inner surface of the frame side wall 21 of the outer frame 20.

[0236] The shape of the cross section of the first carrier longitudinal half guide slot 23011 and / or the first frame longitudinal half guide slot 23012 can be a “V” shape.

[0237] The second longitudinal guide slot 2302 comprises a second carrier longitudinal half guide slot 23021 and a second frame longitudinal half guide slot 23022. The second carrier longitudinal half guide slot 23021 and the second frame longitudinal half guide slot 23022 are opposite in the first direction D1. The second carrier longitudinal half guide slot 23021 is formed on the outer surface of the carrier side wall 31 of the inner carrier 30; the second frame longitudinal half guide slot 23022 is formed on the inner surface of the frame side wall 21 of the outer frame 20.

[0238] The shape of the cross section of the second carrier longitudinal half guide slot 23021 can be an “L” shape or a “U” shape. The shape of the cross section of the second frame longitudinal half guide slot 23022 can be an “L” shape or a “U” shape.

[0239] It is worth mentioning that the contact position of the guide rod 610 with the longitudinal guide slot 230 and the number and area thereof will affect the degree of wear of the inner carrier 30. The present application reduces the wear of the inner carrier 30 caused by long-term movement by designing the contact position of the guide rod 610 with the longitudinal guide slot 230 and the number thereof, improves the durability and reliability of the inner carrier 30, and further improves the durability and reliability of the driving device 1 for the camera module 100.

[0240] In an embodiment of the present application, as shown in FIG. 22, the inner carrier 30 has at least three contact positions formed on the sidewall thereof, which are a first contact position 305, a second contact position 306, and a third contact position 307, respectively. In a preset arrangement direction, the first contact position 305 and the second contact position 306 are located on the same side of the first driving assembly 40, and the third contact position 307 is located on the opposite side of the first driving assembly 40 relative to the first contact position 305 and the second contact position 306. In an example of the present application, the preset arrangement direction is the length direction of the first magnet 42, and is consistent with the second direction D2. The first contact position 305 is located above the second contact position 306. The first contact position 305 is close to the carrier upper surface 302 of the inner carrier 30. The second contact position 306 is close to the carrier lower surface 303 of the inner carrier 30.

[0241] In an embodiment of the present application, at least one component of the first support assembly 60 is in contact with the first contact position 305, at least one component of the first support assembly 60 is in contact with the second contact position 306, and at least one component of the first support assembly 60 is in contact with the third contact position 307, so that a triangular support surface is formed between the first contact position 305, the second contact position 306, the third contact position 307, and the first support assembly 60.

[0242] Specifically, in an embodiment of the present application, the number of contact positions between the inner carrier 30 and the first guide rod 61 is at least two, which are the first contact position 305 and the second contact position 306, respectively. The number of contact positions between the inner carrier 30 and the second guide rod 62 is at least one, which is the third contact position 307. The second contact position 306 is closer to the carrier lower surface 303 of the inner carrier 30 relative to the third contact position 307.

[0243] The inner carrier 30 has two contact protrusions on the groove wall of the first carrier longitudinal semi-conductor groove 23011, which are respectively a first contact protrusion and a second contact protrusion, and the positions of the first contact protrusion and the second contact protrusion form the first contact position 305 and the second contact position 306 of the inner carrier 30 respectively. In this embodiment, the cross section of the first carrier longitudinal semi-conductor groove 23011 and / or the first frame longitudinal semi-conductor groove 23012 can be in the shape of a "V" letter, and the groove wall of the second carrier longitudinal semi-conductor groove 23021 is a plane as a whole, so that the movement of the inner carrier 30 relative to the outer frame 20 is mainly guided by the limiting relationship between the first guide rod 61 and the first carrier longitudinal semi-conductor groove 2301, and meanwhile, the problem of disassembly due to tolerance is avoided. The inner carrier 30 has one contact protrusion on the groove wall of the second carrier longitudinal semi-conductor groove 23021, which is a third contact protrusion, and the position of the third contact protrusion forms the third contact position 307.

[0244] In the optical axis direction D, the height of the third contact protrusion is higher than that of the second contact protrusion and lower than that of the first contact protrusion, and the positions of the first contact protrusion, the second contact protrusion and the third contact protrusion form a triangular position relationship. Correspondingly, in the optical axis direction D, the height of the third contact position 307 is higher than that of the second contact position 306 and lower than that of the first contact position 305, and the first contact position 305, the second contact position 306 and the third contact position 307 form a triangular position relationship. The first contact position 305, the second contact position 306 and the third contact position 307 form a triangular supporting surface between the first guide rod 61 and the second guide rod 62, so that the inner carrier 30 is supported by the first guide rod 61 and the second guide rod 62, and further supported by the outer frame 20.

[0245] Considering that the second guide rod 62 only needs to be in contact with one contact position, the length of the second guide rod 62 can be shorter than that of the first guide rod 61. In this way, it is helpful to maintain the parallelism of the second guide rod 62 and provide more space for the arrangement of other components.

[0246] It should be appreciated that the first guide rod 61 and the second guide rod 62 can be assembled in other ways. For example, the carrier side wall 31 of the inner carrier 30 has a first through hole and a second through hole. The first guide rod 61 is inserted into the first through hole, and the second guide rod 62 is inserted into the second through hole.

[0247] It should be appreciated that the first support assembly 60 can also be implemented in other ways, and a triangular support can also be achieved in other ways. For example, the components in contact with the first contact position 305 can also be a sliding block and a ball, the components in contact with the second contact position 306 can also be a sliding block or a ball, and the components in contact with the third contact position 307 can also be a sliding block or a ball.

[0248] Correspondingly, in a variant embodiment of the present application, the support of the inner carrier 30 is achieved by a guide rod 610 and a ball; accordingly, the first support assembly 60 includes a first guide rod 61 and a first focusing ball. The first guide rod 61 and the first focusing ball are arranged between the carrier side wall 31 and the frame side wall 21 and are separated on both sides of the first magnet 42. At least part of the first guide rod 61 is located in the first longitudinal guide groove 2301, and the first focusing ball is located in the second longitudinal guide groove 2302 and at least partially contacts the third contact position 307. The first contact position 305, the second contact position 306, and the third contact position 307 form a triangular support surface with the first guide rod 61 and the first focusing ball, so that the inner carrier 30 is supported by the first guide rod 61 and the first focusing ball, and in turn is supported by the outer frame 20.

[0249] In another variant embodiment of the present application, the support of the inner carrier 30 is achieved by a guide rod 610 on one side and a sliding block on the other side; accordingly, the first support assembly 60 includes a first guide rod 61 and a first focusing sliding block. The first guide rod 61 and the first focusing sliding block are arranged between the carrier side wall 31 and the frame side wall 21 and are separated on both sides of the first magnet 42. At least part of the first guide rod 61 is located in the first longitudinal guide groove 2301, and the first focusing sliding block is located in the second longitudinal guide groove 2302 and contacts the third contact position 307. The first contact position 305, the second contact position 306, and the third contact position 307 form a triangular support surface with the first guide rod 61 and the first focusing sliding block, so that the inner carrier 30 is supported by the first guide rod 61 and the first focusing sliding block, and in turn is supported by the outer frame 20.

[0255] In another embodiment of the present application, the inner carrier 30 is supported by two sliders on one side and one guide rod 610 on the other side. Two first longitudinal guide slots 2301 are arranged between the inner carrier 30 and the outer frame 20. The first contact position 305 is formed on the slot wall of one of the first longitudinal guide slots 2301 of the inner carrier 30; the second contact position 306 is formed on the slot wall of the other first longitudinal guide slot 2301 of the inner carrier 30; and the third contact position 307 is formed on the second longitudinal guide slot 2302.

[0256] It is worth mentioning that the resultant force of the magnetic force between the inner carrier 30 and the outer frame 20 is expected to be deviated to the side where the first contact position 305 and the second contact position 306 are located, more specifically, the resultant force of the magnetic force between the inner carrier 30 and the outer frame 20 is expected to be deviated to the side where the first contact position 305 and the second contact position 306 are located compared to the side where the third contact position is located in the length direction of the first magnet 42, so that the inner carrier 30 is not easy to overturn relative to the outer frame 20, that is, it is not easy to be deflected relative to the outer frame 20 with the first contact position 305 and the second contact position 306 as the pivot, and for this purpose, the structure of the first support assembly 60 is specially designed.

[0257] Specifically, in the design of the setting position and structure of the focusing magnetic attraction member 9210, the focusing magnetic attraction member 9210 is arranged eccentrically relative to the first magnet 42, i.e., the center of the magnetic attraction member 92 is not consistent with the center of the first magnet 42. More specifically, the center of the focusing magnetic attraction member 9210 is offset relative to the center of the first magnet 42 in the preset arrangement direction towards the first contact position 305 and the second contact position 306. Specifically, the distance between the focusing magnetic attraction member 9210 and the first contact position 305 in the preset arrangement direction is less than the distance between the focusing magnetic attraction member 9210 and the third contact position 307 in the preset arrangement direction; the distance between the focusing magnetic attraction member 9210 and the second contact position 306 in the preset arrangement direction is less than the distance between the focusing magnetic attraction member 9210 and the third contact position 307 in the preset arrangement direction; or specifically, the distance between the focusing magnetic attraction member 9210 and the first contact position 305 in the preset arrangement direction is less than the distance between the first magnet 42 and the first contact position 305 in the preset arrangement direction; the distance between the focusing magnetic attraction member 9210 and the second contact position 306 in the preset arrangement direction is less than the distance between the first magnet 42 and the second contact position 306 in the preset arrangement direction; and the distance between the focusing magnetic attraction member 9210 and the third contact position 307 in the preset arrangement direction is greater than the distance between the first magnet 42 and the third contact position 307 in the preset arrangement direction.

[0258] The magnetic attraction force between the focusing magnetic attraction member 9210 and the first magnet 42 is biased towards the side where the first contact position 305 and the second contact position 306 are located, thereby causing the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 to be biased towards the side where the first contact position 305 and the second contact position 306 are located. From the direction perpendicular to the triangular support surface, the magnetic attraction force between the focusing magnetic attraction member 9210 and the first magnet 42 is in the triangular support surface and is biased towards the side where the first contact position 305 and the second contact position 306 are located, so that the inner carrier 30 is not prone to overturning relative to the outer frame 20, i.e., not prone to being deflected relative to the outer frame 20 with the first contact position 305 and the third contact position 307 as the pivot, or with the second contact position 306 and the third contact position 307 as the pivot.

[0259] Specifically, in order to reduce the size of the driving device 1 for the camera module 100 in the optical axis direction D, the distance between the first contact position 305 and the second contact position 306 in the optical axis direction D is short, and the triangle formed by connecting the first contact position 305, the second contact position 306, and the third contact position 307 in sequence is slender. The center of the magnetic field between the focusing magnetic attraction piece 9210 and the first magnet 42 is close to the connecting line between the first contact position 305 and the third contact position 307, and the center of the magnetic field between the focusing magnetic attraction piece 9210 and the first magnet 42 is close to the connecting line between the second contact position 306 and the third contact position 307. During the optical focusing process, as the inner carrier 30 moves, the center of the magnetic field between the focusing magnetic attraction piece 9210 and the first magnet 42 is more likely to be out of the range of the triangle formed by connecting the first contact position 305, the second contact position 306, and the third contact position 307 in sequence, and the phenomenon of the inner carrier 30 overturning is likely to occur.

[0260] Further, in the deformation embodiment in which the center of the focusing magnetic attraction piece 9210 is biased to the side where the first contact position 305 and the second contact position 306 are located, the portion of the frame circuit board 25 biased to the third contact position 307 is also provided with a structural reinforcement plate to structurally reinforce the portion of the frame circuit board 25 that is exposed and not covered by the focusing magnetic attraction piece 9210.

[0261] Correspondingly, the driving device 1 for the camera module 100 further comprises a first structural reinforcement plate 27, which is arranged on the portion of the frame circuit board 25 not covered by the focusing magnetic attraction piece 9210, is located on the portion of the frame circuit board 25 close to the third contact position 307 in the preset arrangement direction, and is located on the outer side of the frame circuit board 25 in the thickness direction of the frame circuit board 25. The thickness direction of the frame circuit board 25 is consistent with the first direction D1. The first structural reinforcement plate 27 mainly functions in structural reinforcement, has a hardness greater than that of the frame circuit board 25, and has no magnetic conductivity, so as not to affect the magnetic attraction force between the focusing magnetic attraction piece 9210 and the first magnet 42 and cause the inner carrier 30 to easily overturn.

[0262] Specifically, the frame circuit board 25 is generally a flexible circuit board, and the center of the focusing magnetic attraction member 9210 is arranged to be biased to the side where the first contact position 305 and the second contact position 306 are located. The part of the frame circuit board 25 biased to the third contact position 307 is in an exposed state, and is easily deformed due to the flexible structure of the frame circuit board 25. Accordingly, the first structure reinforcing plate 27 is arranged on the part of the frame circuit board 25 in the exposed state and not covered by the focusing magnetic attraction member 9210.

[0263] In order to further bias the magnetic attraction force between the focusing magnetic attraction member 9210 and the first magnet 42 to the side where the first contact position 305 and the second contact position 306 are located, the focusing magnetic attraction member 9210 has at least one first slot 921 (as shown in FIGS. 20 and 23), and the center of the first slot 921 is biased to the side where the third contact position 307 is located relative to the center of the focusing magnetic attraction member 9210.

[0264] In an example of the present application, the first slot 921 is a through slot, that is, the first slot 921 penetrates the focusing magnetic attraction member 9210 in the thickness direction of the focusing magnetic attraction member 9210, wherein the thickness direction of the focusing magnetic attraction member 9210 is consistent with the first direction D1.

[0265] Further, a structure reinforcing plate is arranged on the part of the frame circuit board 25 corresponding to the first slot 921.

[0266] Accordingly, the driving device 1 for the camera module 100 further comprises a second structure reinforcing plate 28, which is arranged on the part of the frame circuit board 25 corresponding to the first slot 921 and located on the outside of the frame circuit board 25 in the thickness direction of the frame circuit board 25. The second structure reinforcing plate 28 mainly functions in structural reinforcement, has a hardness greater than that of the frame circuit board 25, and has no magnetic permeability so as not to affect the magnetic attraction force between the focusing magnetic attraction member 9210 and the first magnet 42 and cause the inner carrier 30 to be easily overturned.

[0267] Specifically, the frame circuit board 25 is generally a flexible circuit board, and the part of the frame circuit board 25 corresponding to the first slot 921 is easily deformed, especially when the first slot 921 is a through slot. The part of the frame circuit board 25 corresponding to the first slot 921 is exposed and not only easily deformed but also easily damaged. Accordingly, the second structure reinforcing plate 28 is arranged on the part of the frame circuit board 25 corresponding to the first slot 921.

[0268] Although the height dimension of the magnetic attraction member 9210 itself is greater than the height dimension of the first magnet 42 itself, i.e., the dimension of the magnetic attraction member 9210 itself in the optical axis direction D is greater than the dimension of the first magnet 42 itself, during the optical focusing process, the first magnet 42 will move relative to the first coil 41 in the optical axis direction D, and the height of the first magnet 42 at least partially located will be higher than the height of the magnetic attraction member 9210, or the height of the first magnet 42 at least partially located will be lower than the height of the magnetic attraction member 9210, so that the magnetic interaction force between the magnetic attraction member 9210 and the first magnet 42 forms a restoring force, which is opposite to the magnetic interaction force between the first coil 41 and the first magnet 42, and promotes the first magnet 42 to return to its initial position, thereby hindering the first magnet 42 from moving in the optical axis direction D according to the expected movement process. The initial position of the first magnet 42 refers to the position of the first magnet 42 when no magnetic interaction force is generated between the first magnet 42 and the first coil 41.

[0269] In order to reduce the influence of the restoring force generated by the magnetic interaction force between the magnetic attraction member 9210 and the first magnet 42 on the movement of the first magnet 42 in the optical axis direction D, the magnetic attraction member 9210 is further provided with a second hollow slot 922. The second hollow slot 922 can be arranged at a position corresponding to the position with stronger magnetism of the first magnet 42. In this way, the driving force requirement for optical focusing can be reduced.

[0270] In an example of the present application, the center region of the first magnet 42 has the strongest magnetism. Accordingly, in this example, the second hollow slot 922 can be arranged at a position corresponding to the center region of the first magnet 42, as shown in FIG. 23. Accordingly, in this example, in the thickness direction of the magnetic attraction member 9210, the second hollow slot 922 corresponds to the center region of the first magnet 42.

[0271] The second hollow slot 922 can be a through slot, i.e., the second hollow slot 922 penetrates through the magnetic attraction member 9210 in the thickness direction of the magnetic attraction member 9210, wherein the thickness direction of the magnetic attraction member 9210 is consistent with the first direction D1.

[0272] It is worth mentioning that, since the first magnet 42 is movable in the optical axis direction D during optical focusing, the size of the second slot 922 in the optical axis direction D should also take into account the size of the optical focusing stroke, so as to avoid the position of the strongest magnetism of the first magnet 42 during movement from being aligned with the part of the first slot 921 and the second slot 922 provided by the focusing magnetic attraction member 9210.

[0273] Correspondingly, the size of the second slot 922 in the optical axis direction D is greater than the optical focusing driving stroke, for example, in an example of the present application, the optical focusing driving stroke is 0.7mm, and the size of the second slot 922 in the optical axis direction D is 1.66mm. The optical focusing driving stroke is equal to the movement stroke of the first magnet 42 in the optical axis direction D.

[0274] Further, "the size of the second slot 922 in the optical axis direction D is greater than the optical focusing driving stroke" is the size requirement of the second slot 922 when the first magnet 42 does not have a neutral zone. When the first magnet 42 has a neutral zone, the size of the second slot 922 in the optical axis direction D is greater than the sum of the optical focusing driving stroke and the size of the neutral zone of the first magnet 42 in the optical axis direction D. The neutral zone of the first magnet 42 refers to the area where the magnetic induction is zero when the external magnetic field of the first magnet 42 is zero.

[0275] Further, a structural reinforcement plate is provided on the part of the frame circuit board 25 corresponding to the second slot 922.

[0276] Correspondingly, the driving device 1 for the camera module 100 further comprises a third structural reinforcement plate, which is provided on the part of the frame circuit board 25 corresponding to the second slot 922 and is located on the outside of the frame circuit board 25 in the thickness direction of the frame circuit board 25. The third structural reinforcement plate mainly serves the purpose of structural reinforcement, has a greater hardness than the frame circuit board 25, and has no magnetic permeability, so as to avoid affecting the magnetic attraction force between the focusing magnetic attraction member 9210 and the first magnet 42 and causing the inner carrier 30 to easily overturn.

[0277] It should be understood that the first and second hollow grooves 921 and 922 can be located at the same position, and correspondingly, the first and second hollow grooves 921 and 922 can be the same hollow groove; and the second and third structural reinforcing plates 28 and 29 can be the same structural reinforcing plate. Correspondingly, the first hollow groove 921 can correspond to the central region of the first magnet 42 while the center of the first hollow groove 921 is offset to the side where the third contact position 307 is located relative to the center of the focusing magnetic attraction element 9210; and the second hollow groove 922 can correspond to the central region of the first magnet 42 while the center of the second hollow groove 922 is offset to the side where the third contact position 307 is located relative to the center of the focusing magnetic attraction element 9210.

[0278] It should also be understood that the first and second hollow grooves 921 and 922 can be in communication with each other.

[0279] It is worth mentioning that the first position sensing element 951 is arranged on the inner side of the frame circuit board 25; when the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 only corresponds to the first and / or second hollow grooves 921 and 922, and the orthographic projection of the other part of the first position sensing element 951 exceeds the first and / or second hollow grooves 921 and 922, the position determination performance of the first position sensing element 951 is unstable, and there is also a risk of being damaged. Correspondingly, ideally, the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 is completely within the first hollow groove 921, and the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 is completely within the second hollow groove 922. Considering the mounting accuracy, the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 is reserved a certain distance from the groove wall of the first hollow groove 921; and the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 is reserved a certain distance from the groove wall of the second hollow groove 922.

[0280] In an example of the present application, the distance between the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 and the groove wall of the first hollow groove 921 is greater than or equal to 0.3 mm; and the distance between the orthographic projection of the first position sensing element 951 in the thickness direction of the frame circuit board 25 and the groove wall of the second hollow groove 922 is greater than or equal to 0.3 mm.

[0281] It is also worth mentioning that the first position sensing element 951 arranged at the inner side of the frame circuit board 25 is opposite to the second structural reinforcement plate 28 and / or the third structural reinforcement plate arranged at the outer side of the frame circuit board 25; in this way, the first position sensing element 951 and the second structural reinforcement plate 28 and / or the third structural reinforcement plate can support and protect the frame circuit board 25 on both sides of the frame circuit board 25, so as to ensure the structural stability and performance stability of the frame circuit board 25 to a certain extent.

[0282] Further, in order to make the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 deviate to the side where the first contact position 305 and the second contact position 306 are located, in a variant embodiment of the present application, the part of the first support assembly 60 abutting against the first contact position 305 and / or the part abutting against the second contact position 306 is designed to have magnetic permeability, and a magnetic attraction magnet 29 is arranged on the inner carrier 30 opposite to the part of the first support assembly 60 abutting against the first contact position 305 and / or the part abutting against the second contact position 306; the magnetic interaction force between the magnetic attraction magnet 29 arranged on the inner carrier 30 and the part of the first support assembly 60 abutting against the first contact position 305 and / or the part abutting against the second contact position 306 makes the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 deviate to the side where the first contact position 305 and the second contact position 306 are located.

[0283] Specifically, the embodiment in which the part of the first support assembly 60 abutting against the first contact position 305 and the second contact position 306 is implemented as the first guide rod 61 having magnetic permeability exemplifies the design manner of the first support assembly 60 and the magnetic attraction magnet 29. The first guide rod 61 abuts against the first contact position 305 and the second contact position 306, and the magnetic attraction magnet 29 is arranged on the inner carrier 30 and opposite to the first guide rod 61; the magnetic interaction force between the magnetic attraction magnet 29 and the first guide rod 61 makes the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 deviate to the side where the first contact position 305 and the second contact position 306 are located.

[0284] It can be understood that when the part of the first support assembly 60 abutting against the first contact position 305 and the second contact position 306 is implemented as other structures, the magnetic attraction magnet 29 is opposite to the other structures implemented as the part of the first support assembly 60 abutting against the first contact position 305 and the second contact position 306.

[0285] For example, when the part of the first support assembly 60 that is in contact with the first contact position 305 is implemented as the second focusing ball and the part of the first support assembly 60 that is in contact with the second contact position 306 is implemented as the third focusing ball, the magnetic attraction magnet 29 is at least partially opposite to the second focusing ball and / or the magnetic attraction magnet 29 is at least partially opposite to the third focusing ball; the magnetic interaction between the magnetic attraction magnet 29 and the second focusing ball and / or the magnetic interaction between the magnetic attraction magnet 29 and the third focusing ball causes the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 to be offset to the side where the first contact position 305 and the second contact position 306 are located.

[0286] For another example, when the part of the first support assembly 60 that is in contact with the first contact position 305 is implemented as the second focusing slider and the part of the first support assembly 60 that is in contact with the second contact position 306 is implemented as the third focusing slider, the magnetic attraction magnet 29 is at least partially opposite to the second focusing slider and / or the magnetic attraction magnet 29 is at least partially opposite to the third focusing slider; the magnetic interaction between the magnetic attraction magnet 29 and the second focusing slider and / or the magnetic interaction between the magnetic attraction magnet 29 and the third focusing slider causes the resultant force of the magnetic attraction force between the inner carrier 30 and the outer frame 20 to be offset to the side where the first contact position 305 and the second contact position 306 are located.

[0287] The magnetic attraction magnet 29 can be embedded in the inner carrier 30 to reduce the extra space occupied by the magnetic attraction magnet 29, thereby reducing the overall volume of the driving device 1 for the camera module 100. In an example of the present application, the inner carrier 30 has a magnet slot 309, and the magnetic attraction magnet 29 is received in the magnet slot 309. In this example, the magnet slot 309 has an opening and the opening faces downward, facilitating the taking, placing and fixing of the magnetic attraction magnet 29, which is specifically manifested as that the magnet slot 309 is recessed upward from the lower surface of the carrier 30. It should be understood that the magnet slot 309 can also not be provided with an opening; the magnetic attraction magnet 29 can be embedded in the inner carrier 30 through insert molding process during the molding process of the inner carrier 30.

[0288] Preferably, as shown in FIG. 18, the center O1 of the magnetic attracting magnet 29 coincides with or is close to the center O2 of the line connecting the first contact position 305 and the second contact position 306 in the optical axis direction D. For example, the distance between the center of the magnetic attracting magnet 29 and the first contact position 305 in the optical axis direction D is greater than or equal to one fourth of the distance between the first contact position 305 and the second contact position 306 in the optical axis direction D and less than or equal to three fourths of the distance between the first contact position 305 and the second contact position 306 in the optical axis direction D. Preferably, the distance between the center of the magnetic attracting magnet 29 and the first contact position 305 in the optical axis direction D is equal to one half of the distance between the first contact position 305 and the second contact position 306 in the optical axis direction D.

[0289] When the part of the first support assembly 60 that is in contact with the first contact position 305 and the second contact position 306 is implemented as the first guide rod 61, preferably, the center of the magnetic attracting magnet 29 coincides with or is close to the center of the first guide rod 61. For example, the distance between the center of the magnetic attracting magnet 29 and the upper end of the first guide rod 61 is greater than or equal to one fourth of the size of the first guide rod 61 in the optical axis direction D and less than or equal to three fourths of the size of the first guide rod 61 in the optical axis direction D.

[0290] Preferably, the upper surface of the magnetic attracting magnet 29 is lower than the upper surface of the first magnet 42, and the lower surface of the magnetic attracting magnet 29 is higher than the lower surface of the first magnet 42, so as to control the height of the magnetic attraction force generated between the magnetic attracting magnet 29 and the first support assembly 60 and reduce the adverse deviation of the overall magnetic attraction force in the optical axis direction D.

[0291] In an embodiment of the present application, the second support assembly 70 is a rolling support assembly, which is rollably installed inside the driving device 1 for the camera module 100. When the outer frame 20 moves, the second support assembly 70 rolls, and accordingly, the second support assembly 70 rollably supports the movement of the outer frame 20 in the first direction D1 and the second direction D2.

[0292] It is worth mentioning that, in the present application, the guiding and supporting of the outer frame 20 is achieved by adopting a single-layer rolling support assembly, which can reduce the height size of the driving device 1 for the camera module 100 to a certain extent. Specifically, in the present application, the second support assembly 70 is arranged on one side of the outer frame 20 in the optical axis direction D, for example, arranged on the upper side of the outer frame 20 or arranged on the lower side of the outer frame 20. Compared with arranging the second support assembly 70 on both the upper side and the lower side of the outer frame 20, arranging the second support assembly 70 on the upper side of the outer frame 20 or arranging the second support assembly 70 on the lower side of the outer frame 20 can reduce the height size of the driving device 1 for the camera module 100 to a certain extent.

[0293] In an embodiment of the present application, as shown in FIG. 2 and FIG. 13, the second support assembly 70 is arranged between the outer frame 20 and the base 11, located on the outer bottom surface of the outer frame 20. Specifically, the second support assembly 70 is arranged between the frame lower surface 203 of the outer frame 20 and the inner surface of the base bottom wall 111 of the base 11.

[0294] The second support assembly 70 comprises at least one ball 71. At least one transverse guide groove 210 is arranged between the outer frame 20 and the base 11, and the ball 71 is rollably arranged in the transverse guide groove 210. As shown in FIG. 2, FIG. 4 and FIG. 5, the transverse guide groove 210 comprises a one-way transverse groove 2101 and a two-way transverse groove 2102. The length direction of the one-way transverse groove 2101 is consistent with the first direction D1, so that the one-way transverse groove 2101 can guide the ball 71 and the outer frame 20 to move along the first direction D1; the length direction of the two-way transverse groove 2102 is consistent with the second direction D2, so that the two-way transverse groove 2102 can guide the ball 71 and the outer frame 20 to move along the second direction D2. When the one-way driving assembly 51 of the second driving assembly 50 drives the outer frame 20 to move along the first direction D1, the ball 71 guides the outer frame 20 to move in the first direction D1 along the one-way transverse groove 2101. When the two-way driving assembly 52 of the second driving assembly 50 drives the outer frame 20 to move along the second direction D2, the ball 71 guides the outer frame 20 to move in the second direction D2 along the two-way transverse groove 2102.

[0295] In one example of the present application, the number of the balls 71 of the second support assembly 70 is greater than or equal to 3, and specifically, the second support assembly 70 includes four balls 71, which are respectively a first ball 711, a second ball 712, a third ball 713 and a fourth ball 714. Correspondingly, the first lateral guide groove, the second lateral guide groove, the third lateral guide groove and the fourth lateral guide groove are arranged between the outer frame 20 and the base 11. The first ball 711 is arranged in the first lateral guide groove; the second ball 712 is arranged in the second lateral guide groove; the third ball 713 is arranged in the third lateral guide groove; and the fourth ball 714 is arranged in the fourth lateral guide groove.

[0296] It is worth mentioning that the longitudinal guide groove 230 for accommodating the guide rod 610 and the lateral guide groove 210 for accommodating the ball 71 are located at different sides of the driving device 1 for the camera module 100. The longitudinal guide groove 230 is located at the first side of the driving device 1 for the camera module 100; and the lateral guide groove 210 is located at the second side and the fourth side of the driving device 1 for the camera module 100.

[0297] The balls 71 are arranged near the two sides where the one-way driving assembly 51 and the two-way driving assembly 52 for realizing anti-shake driving are located, respectively. The action points of the forces generated by the one-way driving assembly 51 and the two-way driving assembly 52 for realizing anti-shake driving are closer to the balls 71, thereby reducing the overturning moment generated during anti-shake driving and reducing the possibility of the inner carrier 30 tilting.

[0298] The first lateral guide groove includes a first one-way lateral groove and a first two-way lateral groove. The length direction of the first one-way lateral groove is consistent with the first direction D1, so that the first one-way lateral groove can guide the first ball 711 and the outer frame 20 to move along the first direction D1; and the length direction of the first two-way lateral groove is consistent with the second direction D2, so that the first two-way lateral groove can guide the first ball 711 and the outer frame 20 to move along the second direction D2. When the one-way driving assembly 51 of the second driving assembly 50 drives the outer frame 20 to move along the first direction D1, the first ball 711 guides the outer frame 20 to move in the first direction D1 along the first one-way lateral groove. When the two-way driving assembly 52 of the second driving assembly 50 drives the outer frame 20 to move along the second direction D2, the first ball 711 guides the outer frame 20 to move in the second direction D2 along the first two-way lateral groove.

[0299] The second lateral guide groove comprises a second one-way lateral groove and a second two-way lateral groove. The length direction of the second one-way lateral groove is consistent with the first direction D1, so that the second one-way lateral groove can guide the second ball 712 and the outer frame 20 to move in the first direction D1; the length direction of the second two-way lateral groove is consistent with the second direction D2, so that the second two-way lateral groove can guide the second ball 712 and the outer frame 20 to move in the second direction D2. When the one-way driving assembly 51 of the second driving assembly 50 drives the outer frame 20 to move in the first direction D1, the second ball 712 guides the outer frame 20 to move in the first direction D1 along the second one-way lateral groove. When the two-way driving assembly 52 of the second driving assembly 50 drives the outer frame 20 to move in the second direction D2, the second ball 712 guides the outer frame 20 to move in the second direction D2 along the second two-way lateral groove.

[0300] The third lateral guide groove comprises a third one-way lateral groove and a third two-way lateral groove. The length direction of the third one-way lateral groove is consistent with the first direction D1, so that the third one-way lateral groove can guide the third ball 713 and the outer frame 20 to move in the first direction D1; the length direction of the third two-way lateral groove is consistent with the second direction D2, so that the third two-way lateral groove can guide the third ball 713 and the outer frame 20 to move in the second direction D2. When the one-way driving assembly 51 of the second driving assembly 50 drives the outer frame 20 to move in the first direction D1, the third ball 713 guides the outer frame 20 to move in the first direction D1 along the third one-way lateral groove. When the two-way driving assembly 52 of the second driving assembly 50 drives the outer frame 20 to move in the second direction D2, the third ball 713 guides the outer frame 20 to move in the second direction D2 along the third two-way lateral groove.

[0301] The fourth transverse guide groove includes a fourth one-way transverse groove and a fourth two-way transverse groove. The length direction of the fourth one-way transverse groove is consistent with the first direction D1, so that the fourth one-way transverse groove can guide the fourth rolling ball 714 and the outer frame 20 to move along the first direction D1; the length direction of the fourth two-way transverse groove is consistent with the second direction D2, so that the fourth two-way transverse groove can guide the fourth rolling ball 714 and the outer frame 20 to move along the second direction D2. When the one-way driving assembly 51 of the second driving assembly 50 drives the outer frame 20 to move along the first direction D1, the fourth rolling ball 714 guides the outer frame 20 to move in the first direction D1 along the fourth one-way transverse groove. When the two-way driving assembly 52 of the second driving assembly 50 drives the outer frame 20 to move along the second direction D2, the fourth rolling ball 714 guides the outer frame 20 to move in the second direction D2 along the fourth two-way transverse groove.

[0302] In the present application, the setting carriers of each one-way transverse groove 2101 and each two-way transverse groove 2102 are different. In one example of the present application, the one-way transverse groove 2101 is arranged on the frame lower surface 203 of the outer frame 20, and the two-way transverse groove 2102 is arranged on the inner surface of the base bottom wall 111 of the base 11.

[0306] In the above embodiments of the present application, the optical image stabilization in two directions is achieved by one outer frame 20. It can be understood that the optical image stabilization in two directions can be achieved by two carriers respectively. It is worth mentioning that when the optical image stabilization in two directions is achieved by two carriers respectively, each carrier for achieving the optical image stabilization can be guided and supported by a single-layer rolling support assembly.

[0309] The first magnet 42 of the first driving assembly 40 is installed on the first side wall 31 of the inner carrier 30. The first coil 41 and the first position sensing element 951 of the first driving assembly 40 are installed on the first side wall of the first sub-carrier. The one-way driving assembly 51 is configured to drive the first sub-carrier to move relative to the base 11 along the first direction D1, thereby driving the inner carrier 30 to move along the first direction D1. The two-way driving assembly 52 is configured to drive the second sub-carrier to move relative to the base 11 along the first direction D1, thereby driving the inner carrier 30 to move along the first direction D1. The second magnet 512 of the one-way driving assembly 51 is installed on the third side wall of the first sub-carrier. The second coil 511 and the second position sensing element 952 of the one-way driving assembly 51 are installed on the third side wall of the second sub-carrier or the third side wall of the base. The third magnet 522 of the two-way driving assembly 52 is arranged on the second side wall of the second sub-carrier. The third coil 521 of the two-way driving assembly 52 is arranged on the second side wall of the base.

[0310] The second support assembly 70 includes a one-way support assembly and a two-way support assembly. The one-way support assembly rollably supports the first sub-carrier to move in the first direction D1. In the optical axis direction D, the one-way support assembly is arranged on one side of the first sub-carrier. For example, the one-way support assembly is arranged on the lower side of the first sub-carrier, clamped between the first sub-carrier and the second sub-carrier, or clamped between the first sub-carrier and the base 11. The one-way support assembly includes at least one ball 71, and the ball 71 of the one-way support assembly is arranged between the first sub-carrier and the second sub-carrier, or between the first sub-carrier and the base 11. The one-way lateral groove 2101 is arranged between the first sub-carrier and the second sub-carrier, or between the first sub-carrier and the base 11. The two-way support assembly rollably supports the second sub-carrier to move in the second direction D2.

For example, the two-way support assembly is arranged on the lower side of the second sub-carrier, clamped between the second sub-carrier and the base 11. The two-way support assembly includes at least one ball 71, and the ball 71 of the two-way support assembly is arranged between the second sub-carrier and the base 11. The two-way lateral groove 2102 is arranged between the second sub-carrier and the base 11.

[0311] It is worth mentioning that, as mentioned above, the magnetic attraction member 92 used for mutual attraction with the second magnet 512 and / or the third magnet 522 to make the outer frame 20 and the base bottom wall 111 approach each other is defined as the anti-shake magnetic attraction member 9220.

[0312] In one example of the present application, the driving device 1 for the camera module 100 includes four anti-shake magnetic attraction members 9220. As shown in FIG. 20, the four anti-shake magnetic attraction members 9220 are a first anti-shake magnetic attraction member 923, a second anti-shake magnetic attraction member 924, a third anti-shake magnetic attraction member 925, and a fourth anti-shake magnetic attraction member 926. The four anti-shake magnetic attraction members 9220 are arranged on the base 11 and located on the bottom wall 111 of the base. The first anti-shake magnetic attraction member 923 and the second anti-shake magnetic attraction member 924 are located below the second magnet 512 in the optical axis direction D and opposite the second magnet 512 in the second direction D2 and separated from the two sides of the second magnet 512. Since the third magnet 522 is arranged adjacent to the second magnet 521, correspondingly, one side of the second anti-shake magnetic attraction member 923 is opposite the second magnet 512 and the other side is opposite the third magnet 522. The third anti-shake magnetic attraction member 925 is located below the third magnet 522 in the optical axis direction D, opposite the third magnet 522 in the first direction D1, and separated from the two sides of the third magnet 522 in the first direction D1 with the second anti-shake magnetic attraction member 925. The fourth anti-shake magnetic attraction member 926 is located below the first magnet 42 in the optical axis direction D, opposite the first magnet 42 in the second direction D2, and separated from the two sides of the first magnet 42 in the second direction D2 with the third anti-shake magnetic attraction member 925.

[0313] It is worth mentioning that in the process of optical anti-shake, the magnetic force between the anti-shake magnetic attraction member 9220 and the second magnet 512 and the third magnet 522 will form a restoring force, thereby hindering the movement of the second magnet 512 and the third magnet 522 in the direction perpendicular to the optical axis direction D according to the expected stroke.

[0314] In order to reduce the influence of the restoring force formed by the magnetic force between the anti-shake magnetic attraction member 9220 and the second magnet 512 and the third magnet 522 on the movement of the second magnet 512 and the third magnet 522 perpendicular to the optical axis direction D, at least one anti-shake magnetic attraction member 9220 is provided with an opening 9201, which can be arranged on the side adjacent to the second magnet 512 and / or the third magnet 522. While reducing the magnetic force between the anti-shake magnetic attraction member 9220 and the second magnet 512 and / or the third magnet 522, enough space is reserved for the movement of the second magnet 512 and / or the third magnet 522.

[0315] Specifically, in one example of the present application, the first anti-shake magnetic member 923 has the opening 9201 on the side adjacent to the second magnet 512; and the second anti-shake magnetic member 924 has the opening 9201 on the side adjacent to the second magnet 512 and on the side adjacent to the third magnet 522, respectively.

[0316] It is worth mentioning that in the embodiments of the present application, a structural reinforcement can be embedded in the base 11 to enhance the structural strength of the base 11. Specifically, considering that the structural strength of the plastic part is insufficient when the base 11 is thinned, the structural strength of the base 11 can be enhanced by embedding a structural reinforcement in the base 11. The structural reinforcement can be made of a metal material, and accordingly, the structural reinforcement is a metal insert. The structural reinforcement can be used to support the ball 71.

[0317] Accordingly, in one example of the present application, as shown in FIG. 17, the driving device 1 for the camera module 100 includes a base structural reinforcement 113, which is arranged on the base 11, for example, embedded in the base 11. It can be designed that the ball 71 is supported on or abuts against the upper surface of the base structural reinforcement 113. The base structural reinforcement 113 is a metal insert.

[0318] A structural reinforcement can also be embedded in the outer frame 20, which is used to enhance the structural strength of the outer frame 20 on the one hand, and to provide support for the ball 71 on the other hand.

[0319] Accordingly, in one example of the present application, the driving device 1 for the camera module 100 includes a frame structural reinforcement 270, which is arranged on the outer frame 20, for example, embedded in the outer frame 20, and can be designed that the ball 71 is supported on or abuts against the lower surface of the frame structural reinforcement 270. The frame structural reinforcement 270 is a metal insert.

[0320] The driving device 1 for the camera module 100 includes a conductive member. The conductive member can be electrically connected to the components (for example, the first coil 41 and the first position sensing element 951) of the first driving assembly 40 that need to be conductive and the components (for example, the second coil 511, the third coil 521, the second position sensing element 952 and the third position sensing element 953) of the second driving assembly 50 that need to be conductive.

[0321] In the present application, the conductive part can be embedded in the outer frame 20 and / or the base 11, which can improve the stability of the electrical connection to a certain extent and avoid the influence of the force of the flexible circuit board on the outer frame 20 on the anti-shake effect to a certain extent compared with the flexible circuit board for connecting the focusing coil and the anti-shake coil.

[0322] In an embodiment of the present application, the first coil 41 and the first position sensing element 951 are mounted on the outer frame 20; the second coil 511, the third coil 521, the second position sensing element 952 and the third position sensing element 953 are mounted on the base 11. Accordingly, a part of the conductive part is arranged on the outer frame 20 to be electrically conductive with the first coil 41 and the first position sensing element 951; another part of the conductive part is arranged on the base 11 to be electrically conductive with the second coil 511, the third coil 521, the second position sensing element 952 and the third position sensing element 953.

[0323] In an embodiment of the present application, as shown in FIG. 13 and FIG. 24, the driving device 1 for the camera module 100 further comprises a base circuit board 13 and at least one base conductive insert 14, the base conductive insert 14 and the base circuit board 13 are arranged in the base 11, wherein the base conductive insert 14 is embedded in the base 11. Specifically, the base conductive insert 14 can be embedded in the base 11 by insert injection molding process. The second coil 511, the third coil 521, the second position sensing element 952 and the third position sensing element 953 are fixed to and electrically connected to the base circuit board 13. Accordingly, the frame circuit board 25 forms the part of the conductive part arranged on the outer frame 20, and the base circuit board 13 and the base conductive insert 14 form the part of the conductive part arranged on the base 11; in other words, the conductive part comprises the base circuit board 13, the base conductive insert 14 and the frame circuit board 25.

[0324] Specifically, the base circuit board 13 can be attached to the base 11, or integrally formed with the base 11, or combined with the base 11 by other means. The base circuit board 13 is arranged on at least two sides of the base 11, for example, the second side and the third side, i.e. the side where the second side wall 1122 is located and the side where the third side wall 1123 is located.

[0325] In one example of the present application, the base circuit board 13 is arranged on the first side, the second side and the third side of the base 11. Specifically, the base circuit board 13 comprises a first portion 131, a second portion 132 and a third portion 133. The first portion 131 is arranged on the base three side wall 1123 and electrically connected to the second coil 511; the second portion 132 is arranged on the base two side wall 1122 and electrically connected to the third coil 521; the third portion 133 is arranged on the base one side wall 1121. The first portion 131 is located on the side of the second coil 511 away from the second magnet 512; the second portion 132 is located on the side of the third coil 521 away from the third magnet 522.

[0326] Structural reinforcement elements can be arranged on the side of the first portion 131 away from the second coil 511 and on the side of the second portion 132 away from the third coil 521 to enhance the structural strength of the base circuit board 13. The first portion 131 and the second portion 132 arranged on the base circuit board 13 mainly serve the purpose of structural reinforcement and do not have magnetic permeability.

[0327] The driving device 1 for the camera module 100 further comprises at least one spring sheet 93. The spring sheet 93 is electrically conductive. The spring sheet 93 is connected to the electrically conductive member.

[0328] Correspondingly, the spring sheet 93 is located between the outer frame 20 and the base 11 and is connected between the portion of the electrically conductive member arranged on the outer frame 20 and the portion of the electrically conductive member arranged on the base 11.

[0329] Each spring sheet 93 has two connection end portions and an elastic extension portion extending between the two connection end portions, wherein at least one of the connection end portions is used to connect the at least one frame circuit board 25; at least one of the connection end portions is used to connect the base circuit board 13 and / or the base electrically conductive insert 14; the elastic extension portion is at least partially formed by a suspension wire. The suspension wire in the spring sheet 93 refers to a portion with a small width size and an elongated linear shape. Multiple portions of the spring sheet 93, in particular the suspension wire, can be fixed to prevent the suspension wire from swinging. Specifically, multiple portions of the spring sheet 93 can be fixed by glue, wherein the glue used to fix the spring sheet 93 is defined as damping glue.

[0330] It is worth mentioning that the spring sheet 93 not only has the function of electrical conduction, but also has a certain reset function due to its elasticity, which helps to achieve the reset of the outer frame 20 relative to the base 11.

[0331] In one example of the present application, the driving device 1 for the camera module 100 includes four elastic sheets 93. The four elastic sheets 93 are respectively a first elastic sheet 931, a second elastic sheet 932, a third elastic sheet 933, and a fourth elastic sheet 934. One end of the first elastic sheet 931, one end of the second elastic sheet 932, one end of the third elastic sheet 933, and one end of the fourth elastic sheet 934 are arranged at the first corner of the frame one, the second corner of the frame two, the third corner of the frame three, and the fourth corner of the frame four of the outer frame 20 respectively. The other end of the first elastic sheet 931, the other end of the second elastic sheet 932, the other end of the third elastic sheet 933, and the other end of the fourth elastic sheet 934 are arranged on the base 11 respectively.

[0332] Specifically, the elastic sheet 93 is directly connected between the frame circuit board 25 and the base circuit board 13, and / or between the frame circuit board 25 and the base conductive insert 14. One end of the elastic sheet 93 is connected to the frame circuit board 25, and the other end is connected to the base conductive insert 14 and / or the base circuit board 13. The base conductive insert 14 is connected to the base circuit board 13. Accordingly, when the other end of the elastic sheet 93 is connected to the base conductive insert 14, it is indirectly connected to the base circuit board 13 through the base conductive insert 14. The elastic sheet 93 can be connected between the frame circuit board 25 and the base circuit board 13, and / or between the frame circuit board 25 and the base conductive insert 14 by welding.

One end of the elastic sheet 93 is connected to the at least one frame electrical connection 250; the other end of the elastic sheet 93 is connected to the at least one base electrical connection 130 or the base conductive insert 14.

[0334] In one example of the present application, the frame circuit board 25 has four frame electrical connections 250, one of which is located on the first side of the outer frame 20, i.e., the side where the frame one side wall 21 is located, and the other three frame electrical connections 250 are located on the fourth side of the outer frame 20, i.e., the side where the frame four side wall 24 is located.

The insert fixing part 1420 is mainly used to be fixed to the base 11 during the injection molding process of the base 11. Accordingly, the insert main body part 1410 extends between the elastic sheet 93 and the base circuit board 13 and has two ends. The insert fixing part 1420 can be designed to extend downward from the insert main body part 1410.

[0337] The driving device 1 for the camera module 100 includes two base conductive inserts 14, which are respectively a first base conductive insert 141 and a second base conductive insert 142. The first base conductive insert 141 is connected to the first part 131 of the base circuit board 13; and the second base conductive insert 142 is connected to the third part 133 of the base circuit board 13. One end of the first base conductive insert 141 is located on the fourth side of the base 11, i.e., the side where the fourth side wall 1124 is located, and the other end is connected to the base electrical connection part 130 located on the third side of the base 11. One end of the second base conductive insert 142 is located on the fourth side of the base 11, i.e., the side where the fourth side wall 1124 is located, and the other end is connected to the base electrical connection part 130 located on the first side of the base 11.

[0338] Accordingly, one of the frame electrical connection parts 250 is higher than the upper surface of the first side wall 21 of the frame, and the other three frame electrical connection parts 250 are higher than the upper surface of the fourth side wall 24 of the frame. Two of the base electrical connection parts 130 are higher than the upper surface of the second side wall 1122 of the base, one of the base electrical connection parts 130 is higher than the upper surface of the first side wall 1121 of the base, and one of the base electrical connection parts 130 is higher than the upper surface of the second side wall 1122 of the base.

[0340] One end of the second elastic sheet 932 is connected to one of the frame electric connection portions 250 located on the side wall 24 of the frame and the other end is connected to one of the base electric connection portions 130 located on the side wall 1122 of the base; the base electric connection portion 130 connected by the second elastic sheet 932 is formed on the second part 132 of the base circuit board 13.

[0341] One end of the third elastic sheet 933 is connected to one of the frame electric connection portions 250 located on the side wall 24 of the frame and the other end is connected to the first base conductive insert 141 located on the side wall 1124 of the base; the first base conductive insert 141 is connected to the base electric connection portion 130 formed on the first part 131 of the base circuit board 13, wherein the first part 131 is arranged on the side wall 1123 of the base.

[0342] One end of the fourth elastic sheet 934 is connected to one of the frame electric connection portions 250 located on the side wall 24 of the frame and the other end is connected to the second base conductive insert 142 located on the side wall 1124 of the base; the second base conductive insert 142 is connected to the base electric connection portion 130 formed on the third part 133 of the base circuit board 13, wherein the third part 133 is arranged on the side wall 1121 of the base.

[0343] As can be seen from the arrangement of each of the elastic sheets 93, one end of the third elastic sheet 933 and one end of the fourth elastic sheet 934 are arranged on the side wall 1124 of the base 11 which is not arranged with the base circuit board 13, and are connected to the base circuit board 13 arranged on the side wall 1123 and the side wall 1121 of the base by being embedded in the base conductive insert 14 of the base 11. Correspondingly, one end of the two base conductive inserts 14 is arranged in the side wall 24 of the frame which is not arranged with the coil (i.e., the first coil 41, the second coil 511 and the third coil 521), and extends to the side wall 1123 and the side wall 1121 of the base adjacent to the side wall 24 of the frame, thereby connecting the part of the side wall 24 of the frame which is not arranged with the coil to the base circuit board 13.

[0344] In general, the first coil 41 and the first position sensing element 951 mounted on the outer frame 20 are electrically connected to the outside through the frame circuit board 25, the base circuit board 13, the base conductive insert 14, and the elastic sheet 93 electrically connected between the frame circuit board 25 and the base circuit board 13; the second coil 511, the second position sensing element 952, the third coil 521, and the third position sensing element 953 mounted on the base 11 are directly electrically connected to the outside through the base circuit board 13.

[0345] In a variant of the present application, the first coil 41 and the first position sensing element 951 are mounted on the base 11; the second coil 511, the third coil 521, the second position sensing element 952, and the third position sensing element 953 are mounted on the base 11.

In this variant, since the conductive member is arranged on the base 11 as a whole, the elastic sheet 93 between the outer frame 20 and the base 11 is not needed.

[0346] As shown in FIG. 2, the driving device 1 for the camera module 100 further comprises a plurality of damping members 94.

The driving device 1 for the camera module 100 can reduce the height size while achieving optical image stabilization and autofocus, thereby reducing the height size of the camera module 100.

[0349] With reference to FIGS. 26-43 of the accompanying drawings, a camera module and a motor thereof according to an embodiment of the present application are illustrated.

The motor 992 is adapted to drive the optical lens 9910 to move to adjust optical performance, such as to achieve optical focusing, optical image stabilization, etc. The optical lens 9910 has an optical axis OA. The photosensitive assembly 9911 is disposed opposite to the optical lens 9910 along the optical axis OA. For the convenience of subsequent description, a direction parallel to the optical axis OA is defined as a longitudinal direction, and a direction perpendicular to the optical axis OA is defined as a transverse direction.

[0350] As shown in FIG. 27, the photosensitive assembly 9911 includes an imaging circuit board 99111, a photosensitive chip 99112, and at least one electronic component 99113 electrically connected to the imaging circuit board 99111.

The electronic component 99113 can be one or more of passive electronic components such as resistors and capacitors, or one or more of active electronic components such as driving chips and memory chips.

[0351] In some embodiments of the present application, the photosensitive assembly 9911 further includes a filter element 99114 held on a photosensitive path of the photosensitive chip 99112, so as to filter light incident on the photosensitive chip 99112 to remove light (e.g., infrared light, etc.) that is not needed for imaging.

[0352] In some embodiments of the present application, the light-sensing assembly 9911 further comprises a bracket 99115, the light-filtering element 99114 is mounted on the bracket 99115, and the bracket 99115 is fixed on the imaging circuit board 99111, so that the light-filtering element 99114 is kept on the light-sensing path of the light-sensing chip 99112 through the bracket 99115. Accordingly, the motor 992 can be fixed on the light-sensing assembly 9911 in a manner of being fixed on the bracket 99115. Alternatively, the motor 992 can also be fixed on the light-sensing assembly 9911 in a manner of being fixed on the imaging circuit board 99111, in which case, if the light-sensing assembly 9911 is still provided with the bracket 99115, the bracket 99115 is recessed inward compared with the edge of the imaging circuit board 99111 to avoid the motor 992, thereby providing a spatial position for fixing the motor 992.

[0353] It can be understood that the specific structure of the light-sensing assembly 9911 shown in FIG. 27 is only illustrative for clarifying the overall scheme of the present application, and should not be regarded as a limitation on the protection scope of the camera module of the present application. Any light-sensing assembly capable of achieving the same or similar functions shall be regarded as an alternative embodiment of the present application, and shall be covered within the protection scope of the present application.

[0354] As shown in FIGS. 26-28, the camera module further comprises a cover 9912, the cover 9912 covers the motor 992, and the cover 9912 is provided with a window 99120, so that the optical lens 9910 is exposed through the window 99120, and the optical lens 9910 can receive the light reflected by the object.

[0355] As shown in FIGS. 27-43, the motor 992 includes a base 993, a frame 994, a carrier 995, and a drive assembly 996. The carrier 995 is configured to carry the optical lens 9910 of the camera module, and the carrier 995 is movably disposed in the frame 994. The drive assembly 996 is configured to drive the carrier 995 to move relative to the frame 994 along the longitudinal direction (i.e., the direction parallel to the optical axis OA), so that the carrier 995 and the optical lens 9910 fixed to the carrier 995 can be driven by the drive assembly 996 to move along the longitudinal direction, thereby achieving the optical focusing function of the camera module. The frame 994 is movably disposed on the base 993, and the drive assembly 996 is further configured to drive the frame 994 to move relative to the base 993 along the lateral direction (i.e., the direction perpendicular to the optical axis OA), so that the frame 994 and the carrier 995 disposed in the frame 994 can be driven by the drive assembly 996 to move along the lateral direction, thereby enabling the optical lens 9910 fixed to the carrier 995 to move along the lateral direction driven by the drive assembly 996, thereby achieving the optical anti-shake function of the camera module.

[0356] As shown in FIGS. 27, 28, and 31, the drive assembly 996 includes a focus drive assembly 9961 configured to drive the carrier 995 to move relative to the frame 994 along the longitudinal direction. The focus drive assembly 9961 includes a focus magnet 99611 and a focus coil 99612 oppositely disposed. One of the focus magnet 99611 and the focus coil 99612 is disposed on the frame 994, and the other is disposed on the carrier 995. In some embodiments of the present application, the focus magnet 99611 is disposed on the carrier 995, and the focus coil 99612 is disposed on the frame 994. Alternatively, in some other embodiments of the present application, the focus magnet 99611 is disposed on the frame 994, and the focus coil 99612 is disposed on the carrier 995.

[0357] As shown in FIG. 27 and FIG. 31, the focus magnet 99611 and the focus coil 99612 are both located at the first side 99201 of the motor 992, wherein the focus magnet 99611 is arranged at the side of the carrier 995 located at the first side 99201, and the focus coil 99612 is arranged at the side of the frame 994 located at the first side 99201, so that the focus magnet 99611 and the focus coil 99612 are oppositely arranged. In particular, the focus coil 99612 is arranged in a longitudinal direction, that is, the center line of the coil hole of the focus coil 99612 is perpendicular to the optical axis OA, and the focus coil 99612 and the focus magnet 99611 are oppositely arranged in a direction perpendicular to the longitudinal direction.

[0358] With continued reference to FIG. 27 and FIG. 31, the motor 992 further comprises a focus magnetic conducting sheet 99613 for enhancing the magnetic field strength of the focus magnet 99611, wherein the focus magnetic conducting sheet 99613 is arranged at the side of the focus magnet 99611 away from the focus coil 99612. Preferably, the focus magnet 99611 is arranged at the side of the carrier 995 in a manner fixed to the focus magnetic conducting sheet 99613, for example, the focus magnetic conducting sheet 99613 is first embedded in the carrier 995, and then the focus magnet 99611 is fixed to the focus magnetic conducting sheet 99613.

[0359] As shown in FIGS. 27-31, the motor 992 further comprises a focusing circuit board 99614, a frame fixing portion 996141 of the focusing circuit board 99614 is fixed to the outside of the frame 994 at the side of the first side 99201, the focusing coil 99612 is fixed to the frame fixing portion 996141 of the focusing circuit board 99614 and electrically connected with the focusing circuit board 99614, wherein the focusing coil 99612 is fixed to the side of the frame fixing portion 996141 close to the focusing magnet 99611. The frame 994 is provided with a frame opening 99400 formed at the side of the frame 994 at the first side 99201, and the focusing coil 99612 is at least partially accommodated in the frame opening 99400. In other words, the focusing coil 99612 is arranged at the side of the frame 994 at the first side 99201 in a manner of being fixed to the frame fixing portion 996141 of the focusing circuit board 99614. As shown in FIG. 28, the frame 994 is provided with a frame positioning protrusion 99401 protruding outward from the outside of the frame 994 at the first side 99201, and the focusing circuit board 99614 is provided with a frame positioning hole 996140 at the frame fixing portion 996141, the frame positioning protrusion 99401 and the frame positioning hole 996140 are matched and corresponded with each other, so that the frame positioning protrusion 99401 can pass through the frame positioning hole 996140, thereby facilitating the fixation of the frame fixing portion 996141 of the focusing circuit board 99614 to the outside of the frame 994 at the first side 99201, and improving the precision and reliability.

[0360] As shown in FIGS. 27 and 31, the motor 992 further comprises a focusing position sensing element 99615 fixed to and electrically connected with the focusing circuit board 99614, the focusing position sensing element 99615 is arranged opposite to the focusing magnet 99611 and used for sensing the magnetic field change of the focusing magnet 99611 to obtain the position change information of the focusing magnet 99611 and the carrier 995 in the longitudinal direction. Preferably, the focusing position sensing element 99615 is arranged in the coil hole of the focusing coil 99612, and the focusing position sensing element 99615 is fixed to the frame fixing portion 996141 of the focusing circuit board 99614.

[0361] As shown in FIGS. 27-29 and 31, the motor 992 further comprises a focusing magnetic absorbing piece 99616 disposed on the side of the focusing coil 99612 away from the focusing magnet 99611 and on the side of the frame 994 located on the first side 99201. It can be understood that the carrier 995 is supported in the frame 994 by the magnetic attraction force between the focusing magnetic absorbing piece 99616 and the focusing magnet 99611. Preferably, the focusing magnetic absorbing piece 99616 is fixed (for example, by adhesive bonding) to the frame fixing portion 996141 of the focusing circuit board 99614 on the side away from the focusing magnet 99611, so that the focusing magnetic absorbing piece 99616 is disposed on the side of the frame 994 located on the first side 99201 in a manner of being fixed to the frame fixing portion 996141 of the focusing circuit board 99614. The focusing magnetic absorbing piece 99616 is provided with a positioning hole 996160 which matches and corresponds to the frame positioning protrusion 99401, so that the frame positioning protrusion 99401 can further penetrate even through the positioning hole 996160 after penetrating through the frame positioning hole 996140, thereby facilitating the fixation of the focusing magnetic absorbing piece 99616 to the frame fixing portion 996141 of the focusing circuit board 99614 on the side away from the focusing magnet 99611, and improving the accuracy and reliability.

[0362] As shown in FIGS. 28, 29, 31 and 32, the focusing magnetic absorbing piece 99616 has at least one hollow hole 996161 extending along the longitudinal direction and in a strip shape. By providing the hollow hole 996161, the longitudinal restoring force between the focusing magnetic absorbing piece 99616 and the focusing magnet 99611 can be reduced, i.e., the magnetic attraction component parallel to the optical axis OA direction between the focusing magnetic absorbing piece 99616 and the focusing magnet 99611 which hinders the realization of the optical focusing function is reduced. It can be understood that as the focusing magnet 99611 moves with the carrier 995 in the longitudinal direction, the center of the focusing magnet 99611 and the center of the focusing magnetic absorbing piece 99616 cannot always be aligned, and thus the magnetic attraction force between the focusing magnetic absorbing piece 99616 and the focusing magnet 99611 cannot always be perpendicular to the optical axis OA. Therefore, the magnetic attraction component parallel to the optical axis OA direction between the focusing magnetic absorbing piece 99616 and the focusing magnet 99611 is the resistance to realize the optical focusing function, which can be referred to as the longitudinal restoring force. The greater the longitudinal restoring force, the more difficult it is to realize the optical focusing function.

[0363] As shown in FIG. 32, the hollow hole 996161 is in a strip shape, which means that the height H of the hollow hole 996161 is greater than the width W of the hollow hole 996161, wherein the height direction of the hollow hole 996161 is parallel to the optical axis OA, and the width direction of the hollow hole 996161 is perpendicular to the optical axis OA. By arranging the hollow hole 996161 in a strip shape, the longitudinal restoring force between the focusing magnetic sheet 99616 and the focusing magnet 99611 can be effectively reduced, so as to enhance the performance of the motor 992 and the camera module.

[0364] With continuous reference to FIG. 32, preferably, the focusing magnetic sheet 99616 is provided with a plurality of hollow holes 996161, and the plurality of hollow holes 996161 are arranged at intervals. The plurality of hollow holes 996161 jointly define a coverage width range R, which completely covers the width range r of the focusing magnet 99611 in the direction in which the focusing magnetic sheet 99616 and the focusing magnet 99611 are arranged opposite to each other, so that the longitudinal restoring force is greatly reduced. According to actual test verification, by arranging the plurality of hollow holes 996161, the ratio of the longitudinal restoring force to the magnetic attraction force in the direction in which the focusing magnetic sheet 99616 and the focusing magnet 99611 are arranged opposite to each other is less than 1:100. In a specific example, the longitudinal restoring force is 0.5 mN, and the magnetic attraction force in the direction in which the focusing magnetic sheet 99616 and the focusing magnet 99611 are arranged opposite to each other is 80 mN, and the ratio of the two is only 1:160, which greatly reduces the longitudinal restoring force, thereby greatly weakening the hindering of the longitudinal restoring force to the optical focusing function.

[0365] It is worth mentioning that in the initial state of the motor 992, in the longitudinal direction (i.e., the height direction), the center of the focusing magnet 99611 is at the same height as the center of the hollow hole 996161, so that the longitudinal restoring force suffered by the carrier 995 when moving upward or downward is similar, thereby facilitating the driving control of the motor 992.

[0366] As shown in FIG. 28 and FIGS. 33-38, the motor 992 further includes a focusing support 99617 disposed between the carrier 995 and the frame 994, the carrier 995 and the frame 994 clamping the focusing support 99617 under the magnetic attraction of the focusing magnetic sheet 99616 and the focusing magnet 99611, the carrier 995 being movably supported in the frame 994 by the focusing support 99617. The carrier 995 is provided with a first carrier side guide 9951 and a second carrier side guide 9952, both of which are formed on the outer side of the carrier 995 on the side of the first edge side 99201, and the first carrier side guide 9951 and the second carrier side guide 9952 are respectively located on both sides of the focusing magnet 99611. The frame 994 is provided with a first frame side guide 9941 and a second frame side guide 9942, both of which are formed on the inner side of the frame 994 on the side of the first edge side 99201, and the first frame side guide 9941 and the second frame side guide 9942 are respectively located on both sides of the focusing coil 99612. The first carrier side guide 9951, the second carrier side guide 9952, the first frame side guide 9941 and the second frame side guide 9942 all extend along the longitudinal direction, the first carrier side guide 9951 and the first frame side guide 9941 are oppositely arranged to form a first accommodation space between the first carrier side guide 9951 and the first frame side guide 9941, the second carrier side guide 9952 and the second frame side guide 9942 are oppositely arranged to form a second accommodation space between the second carrier side guide 9952 and the second frame side guide 9942, and the focusing support 99617 is accommodated in the first accommodation space and the second accommodation space.

[0367] As shown in FIG. 28 and FIGS. 33-37, in some embodiments of the present application, the focusing support portion 99617 comprises at least two first focusing support balls 996171 and at least one second focusing support ball 996172. The first focusing support balls 996171 are disposed between the first carrier side guide groove 9951 and the first frame side guide groove 9941 and are accommodated in the first accommodating space, and the first focusing support balls 996171 can roll and / or slide to a certain extent in the longitudinal direction within the first accommodating space. The second focusing support ball 996172 is disposed between the second carrier side guide groove 9952 and the second frame side guide groove 9942 and is accommodated in the second accommodating space, and the second focusing support ball 996172 can roll and / or slide to a certain extent in the longitudinal direction within the second accommodating space. The number of first focusing support balls 996171 is greater than the number of second focusing support balls 996172, so that the longitudinal movement of the carrier 995 is mainly guided by the first focusing support balls 996171, the first carrier side guide groove 9951 and the first frame side guide groove 9941, and the longitudinal movement of the carrier 995 is secondarily guided by the second focusing support balls 996172, the second carrier side guide groove 9952 and the second frame side guide groove 9942. Preferably, the size of the first focusing support balls 996171 and the size of the second focusing support balls 996172 are the same.

[0368] Therefore, the longitudinal dimension of the second accommodation space required by the second focus support ball 996172 can be smaller than the longitudinal dimension of the first accommodation space required by the first focus support ball 996171. Further considering the positional relationship and cooperation relationship between the components of the motor 992, and the creative avoidance design that can be made by the carrier 995, the present application creatively proposes an embodiment of reducing the longitudinal dimension of the second carrier side guide groove 9952. As shown in FIG. 28, FIG. 34, FIG. 36 and FIG. 37, the second carrier side guide groove 9952 has a lower groove wall 99521 located at the middle position of the carrier 995 in the longitudinal direction, so that the second carrier side guide groove 9952 only extends from the top position of the carrier 995 in the longitudinal direction to the lower groove wall 99521, while the first carrier side guide groove 9951 extends from the top position to the bottom position of the carrier 995 in the longitudinal direction. In this way, the longitudinal dimension of the first carrier side guide groove 9951 is greater than the longitudinal dimension of the second carrier side guide groove 9952, and the second carrier side guide groove 9952 does not extend to the bottom position of the carrier 995 in the longitudinal direction, so as to facilitate the arrangement of the necessary avoidance structure below the second carrier side guide groove 9952, which will be further described later. It can be understood that the lower groove wall 99521 can prevent the second focus support ball 996172 from falling from below and play a limiting and anti-falling role. Accordingly, as shown in FIG. 35, the first frame side guide groove 9941 has a groove bottom wall 99411 located at the bottom position of the frame 994 in the longitudinal direction, which can prevent the first focus support ball 996171 from falling from below and play a limiting and anti-falling role. It is worth mentioning that in the longitudinal direction, the position of the lower groove wall 99521 is always higher than the position of the groove bottom wall 99411.

[0369] As shown in FIG. 28 and FIG. 34 to FIG. 37, the motor 992 further comprises a stopper 99618, wherein the stopper 99618 is fixed to the carrier 995, the stopper 99618 comprises a first stopper arm 996181 and a second stopper arm 996182. The first stopper arm 996181 extends above the first carrier side guide slot 9951 in the longitudinal direction and does not extend into the first carrier side guide slot 9951, so as to provide sufficient longitudinal dimension for the first accommodation space while preventing the first focus support ball 996171 from being removed from above. The second stopper arm 996182 extends into the second carrier side guide slot 9952, so as to further limit the movable space of the second focus support ball 996172 and prevent the second focus support ball 996172 from being removed from above. It can be understood that, by arranging the stopper 99618, the assembly of the first focus support ball 996171 and the second focus support ball 996172 can be facilitated. Specifically, after the carrier 995 and the frame 994 are assembled in alignment, the first focus support ball 996171 can be placed from above between the first carrier side guide slot 9951 and the first frame side guide slot 9941, and the second focus support ball 996172 can also be placed from above between the second carrier side guide slot 9952 and the second frame side guide slot 9942, and then the stopper 99618 is fixed to the carrier 995, so that the first focus support ball 996171 and the second focus support ball 996172 cannot be removed from above.

[0370] As shown in FIG. 38, in some optional embodiments of the present application, the focus support part 99617 can no longer be implemented as a focus support ball, but as two focus support guide rods, one of which is arranged between the first carrier side guide slot 9951 and the first frame side guide slot 9941, and the other of which is arranged between the second carrier side guide slot 9952 and the second frame side guide slot 9942. The focus support guide rods can be fixed to the carrier 995 or the frame 994, so that the stopper 99618 is no longer needed. Preferably, the longitudinal dimension of the focus support guide rod arranged between the second carrier side guide slot 9952 and the second frame side guide slot 9942 is smaller than that of the focus support guide rod arranged between the first carrier side guide slot 9951 and the first frame side guide slot 9941, so that the second carrier side guide slot 9952 still has the lower slot wall 99521 located at the middle position of the carrier 995 in the longitudinal direction, so as to facilitate the arrangement of necessary avoiding structures below the second carrier side guide slot 9952.

[0371] As shown in FIGS. 28-30, the focusing circuit board 99614, while being fixed to the frame 994, also has to be electrically connected with the conductive circuit 9931 embedded in the base 993, that is, the focusing circuit board 99614 should also be provided with a portion fixed to the base 993 to ensure the stability and reliability of the electrical connection between the focusing circuit board 99614 and the conductive circuit 9931. In other words, the focusing circuit board 99614 is fixed to both the frame 994 and the base 993. Since the frame 994 moves relative to the base 993 along the transverse direction under the driving action of the driving assembly 996, the focusing circuit board 99614 inevitably hinders the relative movement between the frame 994 and the base 993, and thus generates additional resistance. In order to reduce the resistance brought by the focusing circuit board 99614 to the movement of the frame 994 relative to the base 993, the focusing circuit board 99614 extends from the side of the frame 994 located at the first side 99201 to the side of the base 993 located at the second side 99202 of the motor 992, wherein the first side 99201 and the second side 99202 of the motor 992 are opposite to each other. In other words, the focusing circuit board 99614 extends from one side of the frame 994 to the opposite side, that is, from the first side 99201 of the motor 992 to the second side 99202 of the motor 992, so as to lengthen the focusing circuit board 99614 and thus facilitate the reduction of the resistance brought by the focusing circuit board 99614.

[0372] Continuing to refer to FIGS. 28-30, the focusing circuit board 99614 includes the frame fixing portion 996141, the base fixing portion 996142, and the connecting portion 996143 connecting and electrically connecting the frame fixing portion 996141 and the base fixing portion 996142, which is preferably a flexible circuit board. The frame fixing portion 996141 is fixed to the outer side of the frame 994 at one side of the first side 99201, the base fixing portion 996142 is fixed to the outer side of the base 993 at one side of the second side 99202, and the connecting portion 996143 is bent and extends between the frame fixing portion 996141 and the base fixing portion 996142, wherein the connecting portion 996143 includes a first connecting strip 996144 and a second connecting strip 996145, the two ends of the first connecting strip 996144 are electrically connected with the frame fixing portion 996141 and the second connecting strip 996145 respectively, and the two ends of the second connecting strip 996145 are electrically connected with the base fixing portion 996142 and the first connecting strip 996144 respectively. The first connecting strip 996144 is inclined relative to the outer side of the frame 994 at the third side 99203 of the motor 992, the second connecting strip 996145 is inclined relative to the outer side of the frame 994 at the second side 99202 of the motor 992, and the included angle between the first connecting strip 996144 and the second connecting strip 996145 is obtuse, so that the resistance caused by the focusing circuit board 99614 can be better reduced, wherein the third side 99203 of the motor 992 is adjacent to the first side 99201 and the second side 99202. The top of the frame 994 at the third side 99203 is provided with an inclined first accommodating groove 9943, and an inclined second accommodating groove 9944 is provided between the frame 994 and the carrier 995 at the top of the second side 99202, wherein the first connecting strip 996144 is at least partially accommodated in the first accommodating groove 9943, and the second connecting strip 996145 is at least partially accommodated in the second accommodating groove 9944, so that the frame 994 can shield and protect the first connecting strip 996144 and the second connecting strip 996145 to some extent from the outside, so as to reduce the risk of damage to the first connecting strip 996144 and the second connecting strip 996145 from the outside, thereby enhancing the reliability of the motor 992, so as to facilitate prolonging the service life of the motor 992 and the camera module.It can be understood that the first connecting band 996144 and the second connecting band 996145 are both arranged in an inclined manner, and the included angle between the two is obtuse, which can greatly reduce the obstruction of the focusing circuit board 99614 to the movement of the frame 994 relative to the base 993 in the transverse direction, and more favorably reduce the resistance caused by the focusing circuit board 99614.

[0373] With continuous reference to FIGS. 28-30, the motor 992 further comprises two shaping portions 996146 for maintaining the bending shape of the bending portion of the focusing circuit board 99614. One of the shaping portions 996146 is arranged at the bending portion connecting the first connecting band 996144 and the frame fixing portion 996141, and is located at the corner of the motor 992 between the first side 99201 and the third side 99203. The other shaping portion 996146 is arranged at the bending portion connecting the second connecting band 996145 and the first connecting band 996144, and is located at the corner of the motor 992 between the third side 99203 and the second side 99202. It is worth mentioning that the shaping portion 996146 can be made of metal or plastic, so as to maintain its own bending shape, thereby maintaining the bending shape of the bending portion of the focusing circuit board 99614. The shaping portion 996146 is fixed in a manner of directly adhering to the bending portion of the focusing circuit board 99614, such as being bonded to the bending portion of the focusing circuit board 99614. Preferably, the shaping portion 996146 is in a curved frame shape, thereby reducing the weight of the shaping portion 996146, so as to avoid excessive resistance caused by the arrangement of the shaping portion 996146 to the movement of the frame 994 relative to the base 993 in the transverse direction. It is also worth mentioning that the shaping portion 996146 is arranged outside the bending portion of the focusing circuit board 99614, which can protect the bending portion of the focusing circuit board 99614 to a certain extent from external damage.

[0374] As shown in FIG. 30, the base 993 is provided with at least one base positioning protrusion 99301 protruding outward from the outer side of the base 993 at the second side 99202, and the focusing circuit board 99614 is provided with at least one base positioning hole 996147 in the base fixing part 996142, the base positioning protrusion 99301 and the base positioning hole 996147 are matched and corresponded to each other, so that the base positioning protrusion 99301 can pass through the base positioning hole 996147, thereby facilitating the fixation of the base fixing part 996142 of the focusing circuit board 99614 to the outer side of the base 993 at the second side 99202, and improving the accuracy and reliability. The conductive circuit 9931 is provided with a focusing circuit board connecting end 99311 exposed to the side of the base 993 at the second side 99202, so as to be welded and connected with the concave pad of the base fixing part 996142 of the focusing circuit board 99614, thereby realizing the electrical connection between the conductive circuit 9931 and the focusing circuit board 99614.

[0375] As shown in FIG. 27, FIG. 28, FIG. 31 and FIG. 39-42, the driving assembly 996 further comprises an anti-shake driving assembly 9962 for driving the frame 994 to move relative to the base 993 along the lateral direction, wherein the anti-shake driving assembly 9962 is arranged at other side of the motor 992 where the focus driving assembly 9961 is not arranged, such as the second side 99202, the third side 99203 and / or the fourth side 99204 of the motor 992. In other words, the anti-shake driving assembly 9962 and the focus driving assembly 9961 are arranged at different sides of the motor 992, which can avoid the anti-shake driving assembly 9962 and the focus driving assembly 9961 from being overlapped with each other in the longitudinal direction, and the longitudinal dimension of the motor 992 can be reduced, thereby facilitating the miniaturization of the motor 992 and the camera module. Moreover, since the anti-shake driving assembly 9962 and the focus driving assembly 9961 are arranged at different sides of the motor 992, the anti-shake driving assembly 9962 and the focus driving assembly 9961 will not generate mutual magnetic interference, which can enhance the performance and reliability of the motor 992 and the camera module. The four sides of the motor 992 are the first side 99201, the second side 99202, the third side 99203 and the fourth side 99204, wherein the first side 99201 and the second side 99202 are opposite to each other, the third side 99203 and the fourth side 99204 are opposite to each other, the third side 99203 is adjacent to the first side 99201 and the second side 99202, and the fourth side 99204 is also adjacent to the first side 99201 and the second side 99202. The anti-shake driving assembly 9962 comprises at least one anti-shake magnet 99621 and at least one anti-shake coil 99622, wherein the anti-shake magnet 99621 and the corresponding anti-shake coil 99622 are arranged opposite to each other, and one of the anti-shake magnet 99621 and the anti-shake coil 99622 is arranged on the frame 994, and the other is arranged on the base 993. In some embodiments of the present application, the anti-shake magnet 99621 is arranged on the frame 994, and the anti-shake coil 99622 is arranged on the base 993. Alternatively, in some other embodiments of the present application, the anti-shake magnet 99621 is arranged on the base 993, and the anti-shake coil 99622 is arranged on the frame 994.

[0376] As shown in FIG. 28, FIG. 39 and FIG. 40, the anti-shake magnet 99621 is arranged on the frame 994 and located at the bottom of the frame 994 in the longitudinal direction, and the anti-shake coil 99622 is arranged on the base 993 and located at the top of the base 993 in the longitudinal direction, so that the anti-shake magnet 99621 and the anti-shake coil 99622 are oppositely arranged. In particular, the anti-shake coil 99622 is arranged transversely, that is, the center line of the coil hole of the anti-shake coil 99622 is parallel to the optical axis OA, and the anti-shake coil 99622 and the anti-shake magnet 99621 are oppositely arranged in the longitudinal direction. It can be understood that, compared with the arrangement mode that the anti-shake coil 99622 is longitudinally arranged on the top of the base 993 in the longitudinal direction, the arrangement mode that the anti-shake coil 99622 is transversely arranged on the top of the base 993 in the longitudinal direction is conducive to reducing the longitudinal dimension of the motor 992, thereby being conducive to the miniaturization of the motor 992 and the camera module. It can also be understood that, compared with the arrangement mode that the anti-shake coil 99622 is located outside the frame 994, the arrangement mode that the anti-shake coil 99622 is located on the lower side of the frame 994 in the longitudinal direction is conducive to reducing the transverse dimension of the motor 992, thereby being conducive to the miniaturization of the motor 992 and the camera module. Therefore, the anti-shake driving assembly 9962 and the focusing driving assembly 9961 provided by the present application are arranged on different sides of the motor 992, and the arrangement mode that the anti-shake coil 99622 is transversely arranged on the top of the base 993 in the longitudinal direction is not only conducive to reducing the longitudinal dimension of the motor 992, but also conducive to reducing the transverse dimension of the motor 992.

[0377] With reference to FIG. 28, FIG. 39 and FIG. 40, preferably, the anti-shake driving assembly 9962 includes three anti-shake magnets 99621 and three anti-shake coils 99622, wherein one anti-shake magnet 99621 is arranged on the bottom of the frame 994 on one side of the third side 99203, and a corresponding anti-shake coil 99622 is arranged on the top of the base 993 on one side of the third side 99203, and the other two anti-shake magnets 99621 are arranged on the bottom of the frame 994 on one side of the second side 99202, and the other two anti-shake coils 99622 are arranged on the top of the base 993 on one side of the second side 99202.

[0378] As shown in FIG. 27, FIG. 31 and FIG. 40, the motor 992 further comprises at least one anti-shake magnet sheet 99623 for enhancing the magnetic field intensity of the corresponding anti-shake magnet 99621, wherein the anti-shake magnet sheet 99623 is arranged on the side of the corresponding anti-shake magnet 99621 away from the corresponding anti-shake coil 99622. Preferably, the anti-shake magnet 99621 is arranged on the bottom of the frame 994 in a manner fixed to the corresponding anti-shake magnet sheet 99623, for example, the anti-shake magnet sheet 99623 is first embedded on the bottom of the frame 994, and then the anti-shake magnet 99621 is fixed to the corresponding anti-shake magnet sheet 99623.

[0379] As shown in FIG. 39, the motor 992 further comprises an anti-shake circuit board 99624 fixed to the top surface of the base 993 in the longitudinal direction, and the anti-shake coil 99622 is fixed to the top surface of the anti-shake circuit board 99624 in the longitudinal direction and electrically connected to the anti-shake circuit board 99624, so that the anti-shake coil 99622 is arranged on the top of the base 993 in the longitudinal direction. In other words, the anti-shake coil 99622 is arranged on the top of the base 993 in a manner fixed to the anti-shake circuit board 99624.

[0380] With continued reference to FIG. 39, preferably, the top surface of the anti-shake circuit board 99624 in the longitudinal direction is provided with a plurality of pads, and the anti-shake coil 99622 can lead out electric connection lines (not shown in the figure) to be welded to the corresponding pads, so as to realize the electrical connection between the anti-shake coil 99622 and the anti-shake circuit board 99624. It can be understood that the position of the pad for electrical connection with the anti-shake coil 99622 shown in FIG. 14 is only illustrative, and in other embodiments of the present application, the position of the pad can be adaptively adjusted according to actual needs.

[0381] As shown in FIG. 39, FIG. 41 and FIG. 42, the conductive circuit 9931 is further provided with anti-shake circuit board connecting ends 99312 exposed to the top surface of the base 993, so as to be welded to the pads arranged on the bottom surface of the anti-shake circuit board 99624, thereby realizing the electrical connection between the conductive circuit 9931 and the anti-shake circuit board 99624. Preferably, the conductive circuit 9931 is provided with four anti-shake circuit board connecting ends 99312 exposed to the top surface of the base 993, and correspondingly, the bottom surface of the anti-shake circuit board 99624 is provided with four pads for electrical connection with the conductive circuit 9931.

[0382] As shown in FIG. 29, FIG. 30, FIG. 39 and FIG. 41, the conductive circuit 9931 is further provided with a photosensitive component connecting end 99313 exposed to the base 993 for electrically connecting with the photosensitive component 9911 of the camera module. Preferably, the photosensitive component connecting end 99313 is exposed to one side of the base 993 located at the third side 99203.

[0383] As shown in FIG. 41, the motor 992 further comprises at least one anti-shake position sensing element 99625 fixed to and electrically connected with the anti-shake circuit board 99624, the anti-shake position sensing element 99625 being configured to sense the magnetic field change of the corresponding anti-shake magnet 99621 to obtain the position change information of the anti-shake magnet 99621 and the frame 994 in the lateral direction. Preferably, the anti-shake position sensing element 99625 is arranged on the bottom surface of the anti-shake circuit board 99624, i.e. on the side of the anti-shake circuit board 99624 away from the anti-shake coil 99622, and is arranged directly below the corresponding anti-shake coil 99622, thereby corresponding to the corresponding anti-shake magnet 99621. Correspondingly, in order to accommodate the anti-shake position sensing element 99625, the base 993 is provided with at least one sensing element accommodating groove 99302 formed by downward recessing the top surface of the base 993. When the motor 992 is provided with three anti-shake magnets 99621 and three anti-shake coils 99622, the motor 992 is provided with three anti-shake position sensing elements 99625, and the base 993 is provided with three sensing element accommodating grooves 99302, the anti-shake position sensing elements 99625 being accommodated in the corresponding sensing element accommodating grooves 99302. It can be understood that, compared with the arrangement of the anti-shake position sensing element 99625 on the top surface of the anti-shake circuit board 99624, the arrangement of the anti-shake position sensing element 99625 on the bottom surface of the anti-shake circuit board 99624 helps to reduce the lateral dimension of the motor 992, thereby facilitating the miniaturization of the motor 992 and the camera module. It can also be understood that, by forming the sensing element accommodating groove 99302 by downward recessing the top surface of the base 993 to accommodate the anti-shake position sensing element 99625, the longitudinal dimension of the motor 992 is reduced, thereby facilitating the miniaturization of the motor 992 and the camera module.

[0384] As shown in FIG. 42, the motor 992 further comprises at least one anti-vibration magnetic absorbing piece 99626, which is arranged on the side of the corresponding anti-vibration coil 99622 away from the corresponding anti-vibration magnetic stone 99621, and is arranged on the base 993. It can be understood that, by the magnetic attraction force between the anti-vibration magnetic absorbing piece 99626 and the corresponding anti-vibration magnetic stone 99621, the frame 994 is stably supported on the base 993. The anti-vibration magnetic absorbing piece 99626 can be directly fixed on the base 993 by bonding or insert molding, or indirectly fixed on the base 993 by being fixed on the anti-vibration circuit board 99624. Preferably, the anti-vibration magnetic absorbing piece 99626 is directly fixed on the base 993, which helps to reduce the complexity of the process, and at the same time reduces the difficulty of mutual alignment and fixation of the anti-vibration circuit board 99624 and the base 993. In some embodiments of the application, the base 993 is provided with at least one magnetic absorbing piece accommodating groove 99303, which is formed by the downward recess of the top surface of the base 993, and the anti-vibration magnetic absorbing piece 99626 is arranged in the magnetic absorbing piece accommodating groove 99303. Preferably, the motor 992 comprises two anti-vibration magnetic absorbing pieces 99626, one of which is located on the third side 99203 of the motor 992, corresponding to one anti-vibration magnetic stone 99621 located on the third side 99203, and the other is located on the second side 99202 of the motor 992, corresponding to two anti-vibration magnetic stones 99621 located on the second side 99202.

[0385] It is worth mentioning that, by arranging the anti-vibration magnetic absorbing piece 99626 in the magnetic absorbing piece accommodating groove 99303 instead of embedding the anti-vibration magnetic absorbing piece 99626 in the base 993 by insert molding process, the transverse size of the motor 992 can be reduced. It can be understood that, if the anti-vibration magnetic absorbing piece 99626 is fixed by insert molding, the base 993 needs to wrap the side of the anti-vibration magnetic absorbing piece 99626, which will increase the transverse size of the base 993.

[0386] With continued reference to FIG. 42, the anti-shake magnetic absorbing piece 99626 has a hole 996261 or a notch 996262. In one aspect, the hole 996261 or the notch 996262 can reduce the lateral restoring force between the anti-shake magnetic absorbing piece 99626 and the anti-shake magnet 99621, i.e., reduce the magnetic absorbing component force between the anti-shake magnetic absorbing piece 99626 and the anti-shake magnet 99621 in a direction perpendicular to the optical axis OA, which hinders the implementation of the optical anti-shake function. The magnetic absorbing component force between the anti-shake magnetic absorbing piece 99626 and the anti-shake magnet 99621 in a direction perpendicular to the optical axis OA is the resistance to the implementation of the optical anti-shake function, which can be referred to as the lateral restoring force. The greater the lateral restoring force, the more difficult it is to implement the optical anti-shake function. The causes and negative effects of the lateral restoring force are similar to those of the aforementioned longitudinal restoring force, and will not be described in detail here. On the other hand, by forming the hole 996261 or the notch 996262 in the anti-shake magnetic absorbing piece 99626, the anti-shake position sensing element 99625 can be avoided to allow the anti-shake position sensing element 99625 to pass through the hole 996261 or the notch 996262 and be accommodated in the sensing element accommodation groove 99302 to reduce the longitudinal dimension of the motor 992, thereby facilitating the miniaturization of the motor 992 and the camera module. The sensing element accommodation groove 99302 is formed on the inner side of the magnetic absorbing piece accommodation groove 99303 and is further recessed downward relative to the magnetic absorbing piece accommodation groove 99303. It is worth mentioning that although the anti-shake magnetic absorbing piece 99626 is provided with the hole 996261 or the notch 996262, in the longitudinal direction, the anti-shake magnetic absorbing piece 99626 still at least partially overlaps the corresponding anti-shake magnet 99621 to ensure that sufficient magnetic absorbing force is generated between the anti-shake magnetic absorbing piece 99626 and the anti-shake magnet 99621.

[0387] As shown in FIG. 28, FIG. 39 and FIG. 42, the motor 992 further comprises an anti-shake support portion 99627, which is arranged between the frame 994 and the base 993, the frame 994 and the base 993 clamping the anti-shake support portion 99627 under the magnetic attraction of the anti-shake magnetic sheet 99626 and the anti-shake magnet 99621, and the frame 994 is movably supported on the base 993 through the anti-shake support portion 99627. Preferably, the anti-shake support portion 99627 comprises a first anti-shake support ball 996271, a second anti-shake support ball 996272 and a third anti-shake support ball 996273, which are respectively located at three corners of the motor 992, wherein the first anti-shake support ball 996271 is located at the corner of the motor 992 between the first side 99201 and the third side 99203, the second anti-shake support ball 996272 is located at the corner of the motor 992 between the third side 99203 and the second side 99202, and the third anti-shake support ball 996273 is located at the corner of the motor 992 between the second side 99202 and the fourth side 99204. The anti-shake coil 99622 located at the third side 99203 is between the first anti-shake support ball 996271 and the second anti-shake support ball 996272, and the two anti-shake coils 99622 located at the second side 99202 are between the second anti-shake support ball 996272 and the third anti-shake support ball 996273. More preferably, the first anti-shake support ball 996271, the second anti-shake support ball 996272 and the third anti-shake support ball 996273 have the same size.

[0388] With continued reference to FIGS. 28, 39 and 42, in order to accommodate the first anti-shake support ball 996271, the second anti-shake support ball 996272 and the third anti-shake support ball 996273, the base 993 is provided with a first boss 99304, a second boss 99305 and a third boss 99306 longitudinally upwardly protruding, the first anti-shake support ball 996271 is accommodated in the ball groove of the first boss 99304, the second anti-shake support ball 996272 is accommodated in the ball groove of the second boss 99305, and the third anti-shake support ball 996273 is accommodated in the ball groove of the third boss 99306. As shown in FIG. 40, the bottom surface of the frame 994 and the areas corresponding to the three ball grooves of the first boss 99304, the second boss 99305 and the third boss 99306 form a plane, and there is no need to further constrain and limit the lateral movement of the frame 994 relative to the base 993 by the bottom surface of the frame 994. In some embodiments of the application, the bottom surface of the frame 994 and the areas corresponding to the three ball grooves of the first boss 99304, the second boss 99305 and the third boss 99306 are each provided with a metal sheet for enhancing the strength of the contact surface, avoiding the frame 994 being damaged by the anti-shake support balls, and preventing the lateral movement of the frame 994 relative to the base 993 from being affected.

[0389] It is worth mentioning that the first anti-shake support ball 996271, the second anti-shake support ball 996272 and the third anti-shake support ball 996273 are arranged, so that the frame 994 can be effectively and reliably supported on the base 993, thereby eliminating the need for arranging a fourth anti-shake support ball at the corner between the fourth side 99204 and the first side 99201 of the motor 992, and eliminating the need for arranging a fourth boss at the corner between the fourth side 99204 and the first side 99201. In this way, the first carrier side guide groove 9951 and the first frame side guide groove 9941 can be closer to the corner between the fourth side 99204 and the first side 99201, and the first carrier side guide groove 9951 and the first frame side guide groove 9941 can also have sufficient longitudinal dimensions to ensure that the first accommodating space formed between the first carrier side guide groove 9951 and the first frame side guide groove 9941 has sufficient longitudinal dimensions to meet the requirement of a larger number of first focus support balls 996171 arranged in the first accommodating space. In other words, the first carrier side guide groove 9951 and the first frame side guide groove 9941 are arranged close to the corner between the fourth side 99204 and the first side 99201, and the second carrier side guide groove 9952 and the second frame side guide groove 9942 are arranged close to the corner between the first side 99201 and the third side 99203, so as to not only ensure that the first carrier side guide groove 9951 has sufficient longitudinal dimensions, but also reduce the lateral dimensions of the motor 992, which is conducive to the miniaturization of the motor 992 and the camera module.

[0390] As shown in FIG. 27, FIG. 28 and FIG. 34-42, the anti-shake circuit board 99624 is located only on the third side 99203, the second side 99202 and the fourth side 99204 of the motor 992, and does not extend to the first side 99201 of the motor 992, so that the focusing magnet 99611 and the anti-shake circuit board 99624 do not overlap in the longitudinal direction, that is, the focusing magnet 99611 and the anti-shake circuit board 99624 are staggered in the longitudinal direction. The focusing magnet 99611 and the anti-shake circuit board 99624 are staggered in the longitudinal direction by a distance greater than the anti-shake stroke of the motor 992, so that the focusing magnet 99611 does not collide with the anti-shake circuit board 99624 when the optical anti-shake function is implemented, where the anti-shake stroke refers to the maximum movement distance of the frame 994 relative to the base 993 in the lateral direction. With reference to FIG. 27, because the focusing magnet 99611 and the anti-shake circuit board 99624 do not overlap in the longitudinal direction, the focusing magnet 99611 can be as low as possible to be closer to the base 993 without being interfered by the anti-shake circuit board 99624, so that the carrier 995 and the focusing magnet 99611 can be closer to the base 993 as a whole, so as to reduce the height of the carrier 995 in the longitudinal direction, thereby reducing the longitudinal size of the motor 992, which is conducive to the miniaturization of the motor 992 and the camera module. It is worth mentioning that when the optical focusing function is implemented, the focusing magnet 99611 can move downward along with the carrier 995 in the longitudinal direction to a position where the bottom surface of the focusing magnet 99611 is lower than the top surface of the anti-shake circuit board 99624, so as to be as low as possible to reduce the longitudinal size of the motor 992. As shown in FIG. 28, FIG. 39, FIG. 41 and FIG. 42, the anti-shake circuit board 99624 is generally U-shaped to meet the above requirements.

[0391] As shown in FIG. 35, since the first carrier side guide groove 9951 is formed on the outer side of the carrier 995 on the side of the first edge side 99201, and the anti-shake circuit board 99624 does not extend to the first edge side 99201 of the motor 992, the first carrier side guide groove 9951 and the anti-shake circuit board 99624 also do not overlap in the longitudinal direction, that is, the first carrier side guide groove 9951 and the anti-shake circuit board 99624 are staggered a certain distance from each other in the longitudinal direction. The distance by which the first carrier side guide groove 9951 and the anti-shake circuit board 99624 are staggered from each other in the longitudinal direction is greater than the anti-shake stroke of the motor 992, so as to prevent the carrier 995 from colliding with the anti-shake circuit board 99624 when the optical anti-shake function is implemented. In this way, in order to ensure that the first carrier side guide groove 9951 has sufficient longitudinal size, the first carrier side guide groove 9951 can extend downward as much as possible, that is, extend in the direction close to the base 993, thereby facilitating the reduction of the longitudinal size of the carrier 995, and thereby the longitudinal size of the motor 992, and facilitating the miniaturization of the motor 992 and the camera module.

[0392] Further referring to FIGS. 34-37, in order to reduce the longitudinal size of the motor 992, the carrier 995 is arranged as close to the base 993 as possible, and the anti-shake circuit board 99624 is avoided by the first avoiding groove 9953 formed at the bottom of the carrier 995 in the longitudinal direction.

[0393] As shown in FIGS. 36-38, the carrier 995 is further provided with a second avoiding groove 9954, which is formed on the side of the carrier 995 on the third edge side 99203, and the second avoiding groove 9954 is located at the bottom of the carrier 995 in the longitudinal direction. The second avoiding groove 9954 is used to avoid the anti-shake coil 99622 located on the third edge side 99203, thereby reducing the lateral size and longitudinal size of the motor 992, and facilitating the miniaturization of the motor 992 and the camera module. Further, according to the foregoing, the second carrier side guide groove 9952 does not extend to the bottom of the carrier 995 in the longitudinal direction, and thus the second avoiding groove 9954 can extend below the second carrier side guide groove 9952 to avoid the first boss 99304, thereby making the carrier 995 and the base 993 more compact, and further reducing the lateral size and longitudinal size of the motor 992.

[0394] As shown in FIG. 43, since the focus magnet 99611 and the focus coil 99612 are located at the first side 99201 of the motor 992, and the anti-shake magnet 99621 and the anti-shake coil 99622 are located at the third side 99203 and the second side 99202 of the motor 992, in order to make the components of the motor 992 more compact, and to reasonably avoid the focus magnet 99611, the focus coil 99612, the anti-shake magnet 99621 and the anti-shake coil 99622, the optical lens 9910 is eccentrically arranged on the motor 992. Specifically, the center OA1 of the lens bearing hole 9950 of the carrier 995 for bearing the optical lens 9910 is eccentric to the fourth side 99204 relative to the center OA2 of the motor 992, wherein the optical axis OA passes through the center OA1 of the lens bearing hole 9950, and the center OA2 of the motor 992 is the intersection of the diagonal lines of the four corners of the motor 992.
