Description

Technical Field

[0001] This invention relates to an optical element driving mechanism. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0003] The aforementioned electronic devices with photographic or video recording functions typically include an optical element driving mechanism to drive optical elements (such as a lens) to move along the optical axis, thereby achieving autofocus (AF) or optical image stabilization (OIS). Light can pass through the aforementioned optical elements and form an image on the photosensitive element. However, the current trend in mobile devices is to achieve smaller size and higher durability; therefore, effectively reducing the size of the optical element driving mechanism and improving its durability has become an important issue.

Specific embodiments of the elements and their arrangements are described below to illustrate the invention. Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of the invention. For example, the specification mentions that a first feature is formed on a second feature.

Moreover, these terms regarding joining and connecting may also include cases where both structures are movable or both structures are fixed.

[0152] First, please refer to Figures 1A to 1F . Figure 1A This is a schematic diagram of an optical element driving mechanism 1000 according to some embodiments of the present invention. Figure 1B This is an exploded view of the optical element drive mechanism 1000. Figure 1C This is a top view of the optical element drive mechanism 1000. Figure 1D It is along Figure 1C The AA section is shown in the cross-sectional view. Figure 1E It is along Figure 1C The BB section is shown in the cross-sectional view. Figure 1F It is along Figure 1C The cross-sectional view shown is a CC section.

[0153] like Figures 1A to 1F As shown, the optical element driving mechanism 1000 mainly includes an outer frame 100 extending along the main axis 800, for example, along the Z direction; a first movable part 200 (including a base 210 and a frame 220); a support 300; a first circuit element 310; a first driving assembly 400 (including a first driving element 410 and a second driving element 420); a first elastic element 510; a second elastic element 520; and a second driving assembly 600. The main axis 800 may extend, for example, along the Z direction.

[0154] The optical element driving mechanism 1000 can be used to drive the optical element 700 to move, thereby achieving the effects of autofocus (AF) or optical image stabilization (OIS). The optical element 700 can be, for example, a lens, mirror, prism, beam splitter, aperture, liquid lens, image sensor, camera module, ranging module, etc. It should be noted that the definition of optical element here is not limited to elements related to visible light; elements related to invisible light (e.g., infrared light, ultraviolet light) can also be included in this invention.

[0155] In some embodiments, the outer frame 100 may also be referred to as the fixed part, and the second drive assembly 600 may be used to drive the first movable part 200 to move relative to the fixed part. The first drive assembly 400 may be used to drive the carrier 300 and the optical element 700 to move relative to the fixed part or the first movable part 200 to achieve the effect of autofocus (AF) or optical image stabilization (OIS).

[0156] In some embodiments, the outer frame 100 and the base 210 are respectively formed with an outer frame opening and a base opening, wherein the center of the outer frame opening corresponds to the main axis 800 of the optical element 700, and the base opening corresponds to an image sensing element (not shown) disposed outside the optical element driving mechanism 1000; thereby, the optical element 700 disposed in the optical element driving mechanism 1000 can focus with the image sensing element in the direction of the main axis 800.

[0157] The aforementioned support 300 has a through hole in which the optical element 700 can be fixed, and the aforementioned second driving element 420 is disposed on the outer surface of the support 300. The first driving element 410 can be fixed to the frame 220.

[0158] The first circuit element 310 of the optical element driving mechanism 1000 is, for example, a flexible printed circuit board (FPC), which can be adhesively fixed to the base 210 of the optical element driving mechanism 1000. In this embodiment, the first circuit element 310 is electrically connected to other electronic components disposed inside or outside the optical element driving mechanism 1000. For example, the first circuit element 310 can transmit electrical signals to the first driving assembly 400 and the second driving assembly 600, thereby controlling the movement of the optical element 700 in the X, Y, or Z directions, thereby realizing the functions of autofocus (AF) or optical image stabilization (OIS).

[0159] It should be understood that the interaction between the first driving element 410 and the second driving element 420 can generate a magnetic force to force the carrier 300 to move relative to the frame 220 along the main axis 800, thereby achieving a fast focusing effect.

[0160] In some embodiments, the first driving component 400 may include, for example, a combination of a magnet and a coil; for instance, the first driving element 410 may be a magnet, and the second driving element 420 may be a coil. In this embodiment, the support 300 and its internal optical element 700 are movably disposed within the frame 220. More specifically, the support 300 can be connected to and suspended within the frame 220 via a first elastic element 510 and a second elastic element 520 made of metal. Figure 1C When the second driving element 420 is energized, it interacts with the magnetic field of the first driving element 410, generating an electromagnetic force to drive the support 300 and the optical element 700 to move relative to the frame 220 along the main axis 800, thereby achieving autofocus. In some embodiments, the first driving assembly 400 may also include a piezoelectric element, shape memory alloy, or other driving element.

[0161] In some embodiments, the base 210 may have additional circuitry (e.g., a second circuit element 320 described later) electrically connected to other electronic components located inside or outside the optical element drive mechanism 1000 to perform functions such as autofocus (AF) and optical image stabilization (OIS).

[0162] The circuitry on the base 210 can also transmit electrical signals to the second drive element 420 through the first elastic element 510 or the second elastic element 520, thereby controlling the movement of the support 300 in the X, Y or Z axis directions.

[0163] During assembly, welding or laser welding can be used to combine the second elastic element 520 with the wires on the base 210 (such as the second circuit element 320 described later), thereby allowing the second drive element 420 to be electrically connected to an external circuit.

[0164] Figure 2A This is a schematic diagram of frame 220. Figure 2B This is a top view of frame 220. Figure 2C This is a schematic diagram of frame 220. (For example...) Figures 2A to 2CAs shown, the frame 220 may primarily include a first surface 221 generally perpendicular to the main axis 800, a second surface 222, and a third surface 223 generally parallel to the main axis 800. The frame 220 may have a first opening 224 on the first surface 221, a second opening 225 on the second surface 222, and a third opening 226 and a fourth opening 227 on the third surface 223. In some embodiments, the first surface 221 may also include a first protrusion 228 and a first recess 229, and the third surface 223 may also include a third recess 231. Furthermore, viewed along the main axis 800, the base 210 and the frame 220 may have a polygonal shape, and a second recess 230 may be present at the corner of the frame 220. The first opening 224 can be used to expose the optical element 700.

[0165] like Figures 2A to 2C As shown, the first surface 221 and the second surface 222 do not coincide, for example, they may be located on planes parallel to each other. In some embodiments, the first protrusion 228 protrudes from the first surface 221 in a direction away from the base 210 (e.g., in the +Z direction), and the first recess 229 is recessed from the first surface 221 in a direction away from the base 210 (e.g., in the -Z direction). Furthermore, the second opening 225 may be located at a corner of the frame 220, and the second recess 230 is recessed in a direction away from the base 210 (e.g., in the +Z direction). Moreover, when viewed along the main axis 800, the second recess 230 is recessed toward the main axis 800, that is, the second recess 230 may retract toward the interior of the frame 220.

[0166] In some embodiments, additional gel (not shown) may be provided on the first recess 229 to simultaneously contact the first recess 229 and the outer frame 100, thereby reducing the resonance effect when the optical element drive mechanism 1000 is operating.

[0167] Figure 3 This is a schematic diagram of some components of the optical element driving mechanism 1000, mainly showing the frame 220, the first driving element 410, and the first adhesive element 901. In some embodiments, such as Figure 2C , Figure 3 As shown, the second recess 230 of the frame 220 may further include a fourth surface 232 and a fifth surface 233 on the back side of the frame 220. The fourth surface 232 may face the first driving element 410 and may be parallel to the spindle 800. In some embodiments, the fifth surface 233 may be adjacent to the fourth surface 232 and may be perpendicular to the spindle 800. The first adhesive element 901 may directly contact the first driving element 410, the fourth surface 232, and the fifth surface 233 to increase the adhesive area, thereby fixing the relative position of the first driving element 410 and the frame 220.

[0168] Figure 4A , Figure 4B This is a schematic diagram of some components of the optical element driving mechanism 1000, where the outer frame 100 is omitted to further show the components below it. In some embodiments, such as Figure 4A , Figure 4B As shown, the base 210 may include a first reinforcing portion 270 located at a corner of the base 210. The first reinforcing portion 270 corresponds to the second recess 230 and extends toward the main shaft 800 in a direction (Z direction). For example, in a direction perpendicular to the main shaft 800 (e.g., the X or Y direction), the first reinforcing portion 270 and the second recess 230 may at least partially overlap. Furthermore, as... Figure 4B As shown, when viewed along the main axis 800, the distance 931 between the second recess 230 and the main axis 800 is less than the distance 932 between the first reinforcing part 270 and the main axis 800 (at this time, the main axis 800 appears as a point). That is to say, compared with the second recess 230, the first reinforcing part 270 is located on the outer side of the optical element drive mechanism 1000. Thus, when the first movable part 200 (base 210, frame 220) moves relative to the outer frame 100 (fixed part), the first reinforcing part 270 can be used to limit the range of motion of the first movable part 200 and can also protect other components.

[0169] like Figure 4A , Figure 4B As shown, the optical element driving mechanism 1000 may further include a second adhesive element 902, a third adhesive element 903, a fourth adhesive element 904, and a fifth adhesive element 905 disposed on the frame 220. For example, the second adhesive element 902 may directly contact the first surface 221 and the second surface 222 of the frame 220, and may be disposed on the second opening 225. For example, when viewed along the main axis 800, the second adhesive element 902 may completely cover the second opening 225. In some embodiments, the third adhesive element 903 may be disposed on the third opening 226, the fourth adhesive element 904 may be disposed on the third recess 231, and the fifth adhesive element 905 may be disposed on the fourth opening 227 and may be exposed outside the frame 220. When viewed along the main axis 800, the second adhesive element 902 does not overlap with the first protrusion 228. In some embodiments, the second adhesive element 902 may be a gel and may directly contact the outer frame 100 to achieve the effect of reducing resonance during operation of the optical element driving mechanism 1000.

[0170] Figure 4C yes Figure 4AThe enlarged side view of the components shows primarily the second adhesive element 902 and the first protrusion 228. Viewed from the direction perpendicular to the main axis 800, the first height 911 of the second adhesive element 902, calculated from the second surface 222, differs from the second height 912 of the first protrusion 228; for example, the first height 911 may be greater than the second height 912. When the frame 220 moves relative to the outer frame 100, the first protrusion 228 can be used to limit the range of motion of the frame 220. This prevents the second adhesive element 902 from being subjected to excessive pressure. Figure 4C As shown, when viewed from the direction perpendicular to the main axis 800, the second adhesive element 902 and the first protrusion 228 can at least partially overlap.

[0171] Figure 5A This is a schematic diagram of some components of the optical element drive mechanism 1000, which mainly shows other components below the frame 220. Figure 5B yes Figure 5A A magnified view of a portion of the image. Figure 5C yes Figure 5A A top view of the components. Figure 5D yes Figure 5C A magnified view of a portion of the image. Figure 6A , Figure 6B This is a schematic diagram of the base 210 and the second circuit element 320.

[0172] like Figures 5A to 6B As shown, the first circuit element 310 and the second circuit element 320 can be disposed in the first movable portion 200 (base 210). For example, the second circuit element 320 can be embedded in the base 210 and partially exposed. The third adhesive element 903 and the fourth adhesive element 904 can also be disposed on the first circuit element 310. For example, the first circuit element 310 can have a fourth recess 312, and the second circuit element 320 can be partially exposed in the fourth recess 312. A first conductive element 331 (e.g., a solder ball) can be disposed at the fourth recess 312 to connect the first circuit element 310 and the second circuit element 320 electrically at the fourth recess 312. In some embodiments, the fourth adhesive element 904 can cover the fourth recess 312 and the first conductive element 331 to protect the connection between the first circuit element 310 and the second circuit element 320. For example, when viewed in the direction perpendicular to the main axis 800, the fourth adhesive element 904 at least partially overlaps with the first conductive element 331 and the fourth recess 312. In the direction perpendicular to the main axis 800, the first circuit element 310 at least partially overlaps with the second circuit element 320.

[0173] The base 210 may have a sixth surface 234 facing the first circuit element 310. The sixth surface 234 may have a first groove 211, a second groove 212, a third groove 213, a fourth groove 214, a fifth groove 215, a sixth groove 216, a seventh groove 217, an eighth groove 218, and a ninth groove 219. Furthermore, the base 210 may also include a first support portion 241, a second support portion 242, a third support portion 243, and a fourth support portion 244 extending along the main axis 800. In some embodiments, the base 210 further includes a first extension portion 251, a second extension portion 252, and a third extension portion 253. The first extension portion 251 is located at the second support portion 242 and extends in a direction perpendicular to the main axis 800; the second extension portion 252 is located at the third support portion 243 and extends in a direction perpendicular to the main axis 800; and the third extension portion 253 is located at the fourth support portion 244 and extends in a direction perpendicular to the main axis 800. In other words, the directions in which the first support portion 241, the second support portion 242, the third support portion 243, and the fourth support portion 244 extend are different from the directions in which the first extension portion 251, the second extension portion 252, and the third extension portion 253 extend. The sixth surface 234 may be the surface of the first support portion 241, the second support portion 242, the third support portion 243, and the fourth support portion 244. The first groove 211, the second groove 212, the third groove 213, the fourth groove 214, the fifth groove 215, the sixth groove 216, the seventh groove 217, and the eighth groove 218 may be used to position the second circuit element 320 relative to the base 210, for example, as positioning points to avoid positional deviations when the second circuit element 320 is placed in the base 210.

[0174] In some embodiments, the second circuit element 320 may include a first circuit unit 321, a second circuit unit 322, a third circuit unit 323, a fourth circuit unit 324, a fifth circuit unit 325, and a sixth circuit unit 326, located on and exposed on the sixth surface 234 of the base 210. In some embodiments, viewed along a direction perpendicular to the main axis 800, the first groove 211, the second groove 212, the third groove 213, and the fourth groove 214 are adjacent to the first circuit element 310. The first groove 211 and the third groove 213 are located on both sides of the first circuit unit 321, and the arrangement direction of the first groove 211 and the third groove 213 is perpendicular to the main axis 800. The second groove 212 and the fourth groove 214 are located on both sides of the first circuit unit 321, and the arrangement direction of the second groove 212 and the fourth groove 214 is perpendicular to the main axis 800. The arrangement direction of the first groove 211 and the second groove 212 is parallel to the main axis 800, and the arrangement direction of the third groove 213 and the fourth groove 214 is parallel to the main axis 800. The third circuit unit 323 may be located between the second circuit unit 322 and the fourth circuit unit 324.

[0175] In some embodiments, in the direction in which the spindle 800 extends, the first circuit unit 321 has a third height 913, the second circuit unit 322 has a fourth height 914, the fourth circuit unit 324 has a fifth height 915, and the first support portion 241 has a sixth height 916. The third height 913 differs from the fourth height 914, the fifth height 915, and the sixth height 916; for example, the third height 913 may be greater than the fourth height 914 and the fifth height 915, and may be less than the sixth height 916. In some embodiments, the first circuit unit 321 may be located between the first support portion 241 and the second support portion 242 to further enhance the mechanical strength at the first support portion 241 and the second support portion 242.

[0176] In some embodiments, the fifth groove 215, the sixth groove 216, the seventh groove 217, and the eighth groove 218 are arranged perpendicular to the main shaft 800. The fourth groove 214 may be adjacent to the second circuit unit 322, the fourth circuit unit 324 may be located between the fifth groove 215 and the sixth groove 216, the fifth circuit unit 325 may be located between the sixth groove 216 and the seventh groove 217, the sixth circuit unit 326 may be located between the seventh groove 217 and the eighth groove 218, and the ninth groove 219 may be located on the fourth support portion 244. In some embodiments, the first extension portion 251, the second extension portion 252, and the third extension portion 253 may directly contact the first circuit element 310, and the first circuit element 310 may directly contact the sixth surface 234 to fix the position of the first circuit element 310. For example, the first extension portion 251, the second extension portion 252, and the third extension portion 253 may be arranged with the first circuit element 310 in the direction of extension of the main shaft 800 to prevent the first circuit element 310 from moving in the Z direction.

[0177] like Figure 5C , Figure 5D As shown, when viewed along the main axis 800, the support 300 also includes a first stop 361 and a second stop 362, extending in a direction perpendicular to the main axis 800. The first stop 361 is located between the second support 242 and the third support 243, while the second stop 362 is located between the third support 243 and the fourth support 244. The first stop 361 and the second stop 362, together with the first support 241, the second support 242, the third support 243, and the fourth support 244, can restrict the range of motion of the support 300 in the Y direction. In the direction perpendicular to the main axis 800, the distance 934 between the support 300 and the fourth support 244 is less than the distance 933 between the second stop 362 and the first circuit element 310. Therefore, direct impact of the support 300 on the first circuit element 310 during movement can be avoided.

[0178] In some embodiments, a sensing element 371 may be disposed on the base 210 or the frame 220, and a corresponding sensing magnetic element 372 may be disposed on the support 300 to sense the position of the support 300 relative to the base 210 or the frame 220. In some embodiments, in the direction perpendicular to the main axis 800, the sensing element 371 may at least partially overlap with the sensing magnetic element 372. In some embodiments, the aforementioned sensing element 371 may include a Hall effect sensor, a magnetoresistive effect sensor (MR sensor), a giant magnetoresistive effect sensor (GMR sensor), a tunneling magnetoresistive effect sensor (TMR sensor), or a fluxgate sensor.

[0179] Figure 6C This is an enlarged cross-sectional view of the optical element driving mechanism 1000. The first circuit element 310 may further include a fifth opening 311, which at least partially overlaps with the third opening 226 of the frame 220 in the direction perpendicular to the main axis 800. A third adhesive element 903 may be disposed in the third opening 226 and the fifth opening 311, may be disposed between the first circuit element 310 and the base 210, and may be disposed in the ninth groove 219. Viewed along the direction perpendicular to the main axis 800, the frame 220 is partially exposed from the fifth opening 311, and the third adhesive element 903 covers the fifth opening 311.

[0180] In some embodiments, viewed along the direction perpendicular to the main axis 800, between the first circuit element 310 and the base 210, the third adhesive element 903 may have a third width 923, the ninth groove 219 may have a fourth width 924 in the direction of the main axis 800, and the fifth opening 311 may have a fifth width 925, and the third width 923 may be greater than the fourth width 924 and the fifth width 925. Thus, the third adhesive element 903 may have a hook-like structure to further fix the relative positions of the base 210, the frame 220, and the first circuit element 310.

[0181] Figure 7AThis is a bottom view of the base 210 and the second circuit element 320. The base 210 may also include a fifth opening 261, a sixth opening 262, a seventh opening 263, and an eighth opening 264, disposed on the seventh surface 235 of the base 210. The seventh surface 235 may be perpendicular to the main shaft 800 and may face away from the outer frame 100 (fixed part). The second circuit element 320 may also include a first circuit contact 341, a second circuit contact 342, a third circuit contact 343, and a fourth circuit contact 344, exposed on the seventh surface 235.

[0182] In some embodiments, the optical element driving mechanism 1000 may further include a second conductive element 332, a third conductive element 333, a fourth conductive element 334, and a fifth conductive element 335, which are respectively disposed at the first circuit contact 341, the second circuit contact 342, the third circuit contact 343, and the fourth circuit contact 344, for example, at least partially overlapping and electrically connected to the first circuit contact 341, the second circuit contact 342, the third circuit contact 343, and the fourth circuit contact 344.

[0183] In some embodiments, viewed along the main axis 800, the first circuit contact 341, the second circuit contact 342, the third circuit contact 343, and the fourth circuit contact 344 are at least partially exposed on the second conductive element 332, the third conductive element 333, the fourth conductive element 334, and the fifth conductive element 335, respectively; that is, the second conductive element 332, the third conductive element 333, the fourth conductive element 334, and the fifth conductive element 335 are not completely covered by the first circuit contact 341, the second circuit contact 342, the third circuit contact 343, and the fourth circuit contact 344. Therefore, the first circuit contact 341, the second circuit contact 342, the third circuit contact 343, and the fourth circuit contact 344 of the second circuit element 320 can be electrically connected to other elements through the second conductive element 332, the third conductive element 333, the fourth conductive element 334, and the fifth conductive element 335.

[0184] In some embodiments, such as Figure 7A As shown, the second conductive element 332, the third conductive element 333, the fourth conductive element 334, and the fifth conductive element 335 are located on both sides of the main shaft 800. The shapes of the fifth opening 261 and the sixth opening 262 are different from the shapes of the seventh opening 263 and the eighth opening 264. For example, the fifth opening 261 and the sixth opening 262 may be circular, while the seventh opening 263 and the eighth opening 264 may be elongated.

[0185] Figure 7B This is a cross-sectional schematic diagram of some components of the optical element drive mechanism 1000, which mainly shows details near the fifth opening 261 (or the sixth opening 262, the seventh opening 263, and the eighth opening 264). Figure 7B As shown, a sixth adhesive element 906 can be disposed between the second drive assembly 600 and the base 210 to fix the relative position between the second drive assembly 600 and the base 210. For example, viewed along the direction perpendicular to the spindle 800, the minimum dimension of the fifth opening 261 has a first width 921. The sixth adhesive element 906 can be partially disposed in the fifth opening 261 and has a second width 922, which is greater than the first width 921. Thus, the sixth adhesive element 906 can have a hook-like shape to further fix the second drive assembly 600 and the base 210. The sixth opening 262, the seventh opening 263, the eighth opening 264 and the sixth adhesive element 906 can also have a similar relationship, which will not be described in detail here.

[0186] Figure 8A , Figure 8B , Figure 8C This is a schematic diagram showing the support 300 and the second driving element 420 viewed from different directions. (See diagram below.) Figures 8A to 8C As shown, the carrier 300 includes a first carrier groove 351, a second carrier groove 352, a third carrier groove 353, and a ramp 354. The first carrier groove 351 protrudes from the second drive element 420. The second carrier groove 352 and the third carrier groove 353 at least partially overlap with the second drive element 420. The ramp 354 is located between the first carrier groove 351 and the second carrier groove 352. Viewed along the spindle 800, the first carrier groove 351 and the second carrier groove 352 at least partially overlap with the second drive element 420, while the third carrier groove 353 protrudes from the second drive element 420. Viewed perpendicular to the spindle 800, the ramp 354 protrudes from the second drive element 420. By providing multiple carrier grooves, additional adhesive elements (e.g., glue) can be placed in each carrier groove to avoid the problem of wire detachment when the second drive element 420 is a coil. The bevel 354 allows the adhesive to flow further into the recesses of each bearing to further prevent the wiring from coming loose.

[0187] Figure 9 This is an exploded view of an optical element driving mechanism 2000 according to some embodiments of the present invention. The optical element driving mechanism 2000 may have similar elements to the aforementioned optical element driving mechanism 1000, the difference being that the optical element driving mechanism 2000 may also include a third elastic element 530 disposed between the frame 220 and the outer frame 100 (fixed part). Figure 10A , Figure 10BThis is a schematic diagram of frame 220 and third elastic element 530. The third elastic element 530 may include a body 531 and an outer chord portion 532 disposed at a corner of the body 531. The body 531 may directly contact the first surface 221 of frame 220, for example, it may be fixed to the first surface 221. The outer chord portion 532 extends from the body 531 in a direction away from the main axis 800. A seventh adhesive element 907 may be disposed on the outer chord portion 532. Viewed from the Z direction, as... Figure 10B As shown, the seventh adhesive element 907 does not overlap with the second opening 225. The first protrusion 228 can be exposed from the third elastic element 530, thereby positioning the third elastic element 530 relative to the frame 220.

[0188] Figure 10C This is a cross-sectional view of some components of the optical element drive mechanism 2000, which mainly shows the outer frame 100, the frame 220, the third elastic element 530, and the seventh adhesive element 907. The seventh adhesive element 907 can directly contact the outer frame 100 to avoid resonance when the frame 220 moves relative to the outer frame 100.

[0189] In some embodiments, a second adhesive element 902 and a seventh adhesive element 907 may be provided simultaneously. For example, Figure 10D , Figure 10E This is a schematic diagram showing the simultaneous installation of the second adhesive element 902 and the seventh adhesive element 907. (Example) Figure 10D As shown, viewed from the Z direction, the seventh adhesive element 907 does not overlap with the second adhesive element 902, and the outer chord portion 532 surrounds the second adhesive element 902, meaning the second adhesive element 902 may not directly contact the third elastic element 530. Figure 10E As shown, the second adhesive element 902 and the seventh adhesive element 907 can both directly contact the outer frame 100 to avoid resonance when the frame 220 moves relative to the outer frame 100.

[0190] Figure 11A , Figure 11B , Figure 11C This is a schematic diagram of the second drive component 600 as viewed from different directions. In some embodiments, such as... Figure 11A , Figure 11B , Figure 11C As shown, the second drive assembly 600 may mainly include a plurality of third drive elements 610, a connecting element 620, a second movable part 630, a third circuit element 640, and a substrate 650.

[0191] The second movable part 630 can be fixed to the base 210, for example by means of... Figure 7BThe sixth adhesive element 906 is fixed in place. The connecting element 620 can be used to elastically connect the second movable part 630 and the third circuit element 640, allowing relative movement between them. The third circuit element 640 can be fixed to the substrate 650. The substrate 650 can be fixed to the outer frame 100 (fixed part). The third driving element 610 can connect the first connecting portion 631 of the second movable part 630 and the second connecting portion 641 of the third circuit element 640 to drive the second movable part 630 to move relative to the third circuit element 640.

[0192] In some embodiments, the third driving element 610 may be made of shape memory alloy (SMA) and has an elongated shape extending in one direction. Shape memory alloy is an alloy material that, upon heating, can completely eliminate the deformation that occurs at lower temperatures and restore its original shape before deformation. For example, when a shape memory alloy undergoes limited plastic deformation below its phase transformation temperature, it can be restored to its original shape before deformation by heating. This allows the second movable part 630 to move relative to the third circuit element 640, thereby driving the optical element 700 to move, achieving an optical image stabilization effect.

[0193] In summary, the present invention provides an optical element driving mechanism, including a fixed part, a first movable part, and a second driving assembly. The first movable part and the fixed part are arranged along a main axis and can move relative to the fixed part. The second driving assembly is used to drive the first movable part to move relative to the fixed part. Viewed along the main axis, the first movable part includes a frame with a polygonal structure and a second recess at a corner. Thus, optical image stabilization can be achieved, and miniaturization can also be achieved.

[0194] The special relative positions and size relationships of the components disclosed in this invention not only enable the drive mechanism to achieve thinning in a specific direction and miniaturization of the whole, but also further improve the optical quality of the system (such as shooting quality or depth sensing accuracy) by matching different optical modules, and further utilize each optical module to achieve a multi-anti-shake system to greatly improve the anti-shake effect.

Furthermore, the scope of protection of the present invention is not limited to the processes, machines, manufacturing methods, material compositions, apparatuses, methods, and steps described in the specific embodiments of the specification.

Therefore, the scope of protection of the present invention includes the aforementioned processes, machines, manufacturing methods, material compositions, apparatuses, methods, and steps.
