Description

Technical Field

[0001] This disclosure 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.

[0149] O: Spindle Detailed Implementation

[0150] The following discloses many different implementations or examples to carry out the different features provided. Specific embodiments of the elements and their arrangements are described below to illustrate this disclosure. Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of this disclosure. For example, the specification mentions that a first feature is formed on a second feature. This may include embodiments where the first and second feature are in direct contact, or embodiments where there are other features between the first and second feature; in other words, the first and second feature are not in direct contact.

[0151] Furthermore, repeated reference numerals or designations may be used in different embodiments. These repetitions are merely for the purpose of clearly and simply describing this disclosure and do not represent a specific relationship between the different embodiments and / or structures discussed. Additionally, the formation, connection, and / or coupling to another feature component in this disclosure may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed to insert into the aforementioned feature component, such that the aforementioned feature components may not be in direct contact. Furthermore, spatially related terms such as “vertical,” “above,” “up,” “below,” “bottom,” and similar terms (e.g., “downward,” “upward,” etc.) may be used to facilitate the description of the relationship between one element(s) or feature(s) in the illustrations and another element(s) or feature(s). These spatially related terms are intended to cover different orientations of the device including the feature.

[0152] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0153] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify elements of the claims does not imply or represent any prior ordinal number for the claimed element, nor does it represent the order of one claimed element with another, or the order of manufacturing methods. The use of multiple ordinal numbers is only to enable a claimed element with a certain name to be clearly distinguished from another claimed element with the same name.

[0154] Furthermore, in some embodiments of this disclosure, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or they may refer to two structures that are not in direct contact, with other structures disposed between them. Moreover, these terms regarding joining and connection may also include cases where both structures are movable or both structures are fixed.

[0155] Please refer to the following first. Figures 1A to 1E ,in Figure 1A This is a schematic diagram of an optical element driving mechanism 1000 shown according to some embodiments of the present disclosure. 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 cross-sectional view shown by line segment AA, Figure 1E It is along Figure 1C The cross-sectional view is shown by line segment BB.

[0156] It should be noted that the optical element driving mechanism 1000 in this embodiment can be used to carry an optical element (such as the optical element 400 mentioned later), such as a lens, mirror, prism, beam splitter, aperture, liquid lens, image sensor, camera module, ranging module, etc., but is not limited thereto. It should be noted that the definition of an optical element here is not limited to elements related to visible light; elements related to invisible light (such as infrared light, ultraviolet light) may also be included in this disclosure.

[0157] like Figures 1A to 1D As shown, in some embodiments, the optical element driving mechanism 1000 mainly includes an outer frame 110, a frame 115, a base 120, a movable part 130, a first magnetic element 142, a first coil 144, a second circuit element 150, a third circuit element 160, a fourth circuit element 170, a first circuit element 180, a first damping element 190, a second damping element 192, and a position sensing assembly 200, arranged along the main axis O. The optical element driving mechanism 1000 can be used to drive the optical element to move, so as to achieve the effect of autofocus (AF) or optical image stabilization (OIS).

[0158] The outer frame 110, frame 115, and base 120 can be collectively referred to as the fixed portion 510. The movable portion 130 is movably connected to the fixed portion 510, meaning that the movable portion 130 can move relative to the fixed portion 510. Furthermore, the first magnetic element 142 and the first coil 144 can be collectively referred to as the drive assembly 140, which is used to drive the movable portion 130 to move relative to the fixed portion 510. The first circuit element 180, the second circuit element 150, the third circuit element 160, and the fourth circuit element 170 can be collectively referred to as the circuit assembly 600, which is electrically connected to the drive assembly 140. The drive assembly 140 can be electrically connected to an external circuit (e.g., the subsequent external circuit 610) via the circuit assembly 600. In some embodiments, the drive assembly 140 can be electrically connected to the second circuit element 150 via the third circuit element 160.

[0159] The aforementioned outer frame 110 and base 120 can be combined to form the housing of the optical element driving mechanism 1000, for example, forming a receiving space 500, and other components of the optical element driving mechanism 1000 (e.g., frame 115, movable part 130, etc.) can be disposed in the receiving space 500. The base 120 can be fixedly connected to the outer frame 110. It should be understood that the outer frame 110 and the base 120 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 O, and the base opening corresponds to the image sensing element (not shown) disposed outside the optical element driving mechanism 1000; thereby, the optical element disposed in the optical element driving mechanism 1000 can focus with the image sensing element in the direction of the main axis O.

[0160] The aforementioned movable part 130 has a through hole in which an optical element can be fixed, and the aforementioned first coil 144 is disposed on the outer surface of the movable part 130. The first magnetic element 142 can be fixed to the fixed part 510 (e.g., base 120). It should be understood that, through the interaction between the first magnetic element 142 and the first coil 144, a magnetic force can be generated to force the movable part 130 to move relative to the fixed part 510 along the main axis O, thereby achieving a rapid focusing effect.

[0161] In this embodiment, the movable part 130 and its internal optical elements are movably disposed within the accommodating space 500. More specifically, the movable part 130 can be connected to and suspended within the fixed part 510 via a third circuit element 160 and a fourth circuit element 170 made of metal. When the aforementioned first coil 144 is energized, the first coil 144 interacts with the magnetic field of the first magnetic element 142, generating an electromagnetic force to drive the movable part 130 and the aforementioned optical elements to move relative to the fixed part 510 along the main axis O, thereby achieving an autofocus effect.

[0162] In some embodiments, the base 120 may include a second circuit element 150 electrically connected to other electronic components disposed inside or outside the optical element drive mechanism 1000, for performing functions such as autofocus (AF) and optical image stabilization (OIS). The second circuit element 150 may also transmit electrical signals to the first coil 144 via a third circuit element 160, thereby controlling the movement of the movable part 130 in the X, Y, or Z axis directions. During assembly, the second circuit element 150 and the third circuit element 160 may be joined by soldering or laser welding, thereby allowing the first coil 144 to be electrically connected to an external circuit. Furthermore, the second circuit element 150 may also be electrically connected to a fourth circuit element 170, thereby allowing other optical units (e.g., optical unit 300, described in subsequent embodiments) to be electrically connected via the fourth circuit element 170.

[0163] In some embodiments, several additional drive coils (not shown) may be embedded in the base 120 to interact with the first magnetic element 142 to drive the movable part 130 to move. When the first coil 144 and the additional drive coils in the base 120 interact with the first magnetic element 142, they can generate driving forces in different directions to perform functions such as autofocus (AF) and optical image stabilization (OIS).

[0164] Figures 2A to 2C This is a schematic diagram of the outer frame 110 and the frame 115 viewed from different directions. In some embodiments, the materials of the outer frame 110 and the frame 115 may include metal, and the materials of the outer frame 110 and the frame 115 may be different. For example, the magnetic permeability of the frame 115 may be greater than that of the outer frame 110 to achieve the function of magnetic conduction.

[0165] like Figures 2A to 2C As shown, the outer frame 110 has a first top wall 111 and a first side wall 112. The first top wall 111 is perpendicular to the main axis O, and the first top wall 111 is connected to the first side wall 112 via a first bend 113. The frame 115 includes a second top wall 116 and a second side wall 117. The first top wall 111 may be parallel to the second top wall 116, and the first side wall 112 may be parallel to the second side wall 117. The second top wall 116 is connected to the second side wall 117 via a second bend 118.

[0166] It should be noted that, such as Figures 2A to 2BAs shown, a first opening 532 and a second opening 534 are provided between the second top wall 116 and the second side wall 117, and a second bend 118 is located between the first opening 532 and the second opening 534. When viewed along the main axis O, the first bend 113 at least partially overlaps with the first opening 532 and the second opening 534. In other words, the first bend 113 can be exposed from the first opening 532 and the second opening 534.

[0167] When viewed along the main axis O, the first sidewall 112, the second top wall 116, and the second sidewall 117 are located on a first side 541 of the optical element drive mechanism 110, which has a polygonal structure. Furthermore, the first top wall 111 and the second top wall 116 can be spaced apart by a distance 550 greater than zero, while the first sidewall 112 and the second sidewall 117 can be in direct contact or spaced apart by a distance less than 550. In other words, the shortest distance between the first top wall 111 and the second top wall 116 can be greater than the shortest distance between the first sidewall 112 and the second sidewall 117.

[0168] Figures 3A to 3C This is a schematic diagram of some components of the optical element drive mechanism 1000, where the outer frame 110 is omitted to further show the internal structure. (See diagram for details.) Figure 3C As shown, the optical element driving mechanism 1000 may include a first side 541, a second side 542, a third side 543, and a fourth side 544, with the second side 542 and the third side 543 adjacent to the first side 541 and the fourth side 544. The extending directions of the first side 541 and the fourth side 544 may be perpendicular to the extending directions of the second side 542 and the third side 543. The base 120 may include a first boundary 545, a second boundary 546, a third boundary 547, and a fourth boundary 548, located on the first side 541, the second side 542, the third side 543, and the fourth side 544, respectively.

[0169] In some embodiments, when viewed along the main axis O, the first magnetic element 142 is located on the first side 541 and the fourth side 544. Furthermore, as... Figure 1D As shown, the first magnetic element 142 can be fixed to the frame 115, for example, fixedly disposed on the second sidewall 117. Furthermore, as... Figure 3B , Figure 3C As shown, the first magnetic element 142 can be exposed from the first opening 532 and the second opening 534. In other words, the first magnetic element 142 can protrude from the second sidewall 117.

[0170] In some embodiments, the first damping element 190 and the second damping element 192 may be disposed between the movable part 130 and the fixed part 510 (e.g., the base 120) to absorb abnormal vibrations of the movable part 130 relative to the fixed part 510, thereby preventing vibrations from affecting image quality. For example, the first damping element 190 and the second damping element 192 may directly contact the movable part 130 and the base 120. In some embodiments, the first damping element 190 and the second damping element 192 may comprise non-metallic materials, such as resin, plastic, rubber, or silicone, but are not limited thereto.

[0171] like Figure 3C As shown, the first damping element 190 has a shortest distance 551 with the first boundary 545 and a shortest distance 552 with the second boundary 546, and the shortest distances 551 and 552 are different. For example, the shortest distance 551 may be greater than the shortest distance 552. Furthermore, the second damping element 192 has a shortest distance 553 with the first boundary 545 and a shortest distance 554 with the third boundary 547, and the shortest distances 553 and 554 are different. For example, the shortest distance 553 may be greater than the shortest distance 554. Thus, vibrations in a specific direction can be absorbed to further stabilize the optical element drive mechanism 1000.

[0172] In some embodiments, the first circuit element 180 and the second sensing component 200 may be disposed on the second side 542. For example, the second sensing component 200 may be located at the center of the second side 542. For instance, the second sensing component 200 may include a sensing element 201 and a sensing magnetic element 202, which may be respectively located on the fixed part 510 and the movable part 130. The sensing element 201 may be used to sense changes in the magnetic field, and may include, for example, a Hall effect sensor, a magnetoresistance effect sensor (MR sensor), a giant magnetoresistance effect sensor (GMR sensor), a tunneling magnetoresistance effect sensor (TMR sensor), or a fluxgate sensor. The sensing magnetic element 202 may be, for example, a magnet, which may emit a magnetic field. When the movable part 130 moves relative to the fixed part 510, the magnetic field emitted by the sensing magnetic element 202, sensed by the sensing element 201, changes. This change in magnetic field allows the determination of the motion state of the movable part 130 relative to the fixed part 510. Furthermore, the sensing element 201 can be electrically connected to the first circuit element 180.

[0173] Figure 4A , Figure 4B This is a schematic diagram of some components of the optical element drive mechanism 1000 when viewed from different directions. Figure 5 This is a schematic diagram of some components of the optical element driving mechanism 1000, mainly showing some components located on one side of the first barrier 121, while omitting components such as the first circuit element 180. Figure 4A , Figure 4B , Figure 5 As shown, the optical element driving mechanism 1000 may further include a first barrier 121 and a second barrier 122, located on opposite sides of the base 120, extending along the main axis O, and integrally formed with the base 120. The first barrier 121 may include a first stop surface 123 facing the movable part 130, for limiting the movement of the movable part 130 relative to the fixed part 510. Furthermore, as... Figure 3C As shown, the first retaining wall 121 is located on the second side 542, while the second retaining wall 122 is located on the third side 543. Furthermore, a first damping element 190 may be located on the first retaining wall 121, and a second damping element 192 may be located on the second retaining wall 122. In some embodiments, a first circuit element 180 may be fixed to the first retaining wall 121, for example, on the side opposite to the first stop surface 123.

[0174] Furthermore, a first adhesive element 210 may be provided between the outer frame 110 and the base 120, for example, a first connecting reinforcement structure 220 may be provided at the corner of the base 120. The first connecting reinforcement structure 220 may be located on the first retaining wall 121 and may have a recessed structure. The first connecting reinforcement structure 220 may increase the contact area between the first adhesive element 210 and the first retaining wall 121, thereby strengthening the adhesive force of the first adhesive element 210.

[0175] In some embodiments, the first barrier 121 may include a first recess 231, a second recess 232, and a third recess 233. It should be noted that the first recess 231 and the third recess 233 may be located within the second recess 232. The first recess 231 may be used to accommodate a position sensing component 200, the second recess 232 may be used to accommodate a first circuit element 180, and the third recess 233 may be used to accommodate a second adhesive element 240. In some embodiments, the first circuit element 180 may be fixedly connected to the first barrier 121 via the second adhesive element 240. In some embodiments, the depth of the first recess 231 may be greater than the depth of the third recess 233. For example, the first recess 231 may penetrate the entire first barrier 121, while the third recess 233 may not penetrate the first barrier 121.

[0176] Figure 6A This is a schematic diagram of some components of the optical element drive mechanism 1000. Figure 6B yes Figure 6A Enlarged image, Figure 6C yes Figure 6A The component shown is a cross-sectional view along line segment CC. Figure 6D yes Figure 6C Enlarged image, Figure 6E This is a partially enlarged view of the first circuit component 180 and the second circuit component 150. (See attached image.) Figures 6A to 6E As shown, the second circuit element 150 may be disposed in the base 120, for example, it may include at least a partially embedded portion not exposed in the base 120 and an exposed portion exposed in the base 120. The first circuit element 180 may include a first contact 182, and the second circuit element 150 may include a second contact 152, and can be connected via a first electrical connection element 250 ( Figure 6D They are electrically connected to each other.

[0177] In some embodiments, the first electrical connection element 250 may directly contact the first surface 183 of the first circuit element 180 and the second surface 154 of the second circuit element 150. The first electrical connection element 250 may include, for example, conductive adhesive, solder, or a welding element, etc., which can be used for electrical connection. The first surface 183 may not be parallel to the second surface 154; for example, they may be perpendicular to each other. Figure 6E As shown, in the X direction, the first surface 183 and the second surface 154 at least partially overlap. For example, at least a portion of the first surface 183 and the second surface 154 have the same Z coordinate. Furthermore, the second contact 152 may also include a third surface 155, in the direction extending from the principal axis O, where the second surface 154 and the third surface 155 may at least partially overlap. Figure 6E As shown, in the X direction, the first surface 183 and the third surface 155 do not overlap. In other words, the lowermost point of the first surface 183 in the Z direction can be located between the two planes defined by the second surface 154 and the third surface 155.

[0178] Figure 7A , Figure 7B This is a schematic diagram of the second circuit element 150, the third circuit element 160, and the fourth circuit element 170 viewed from different directions. The third circuit element 160 and the fourth circuit element 170 may have a plate-like structure. The second circuit element 150 may be electrically connected to the third circuit element 160 and the fourth circuit element 170. For example, the third circuit element 160 may include a third contact 263 and a fourth contact 264, and the fourth circuit element 170 may include a fifth contact 265 and a sixth contact 266. The third circuit element 160 can be electrically connected to the second circuit element 150 through the third contact 263 and the fourth contact 264, while the fourth circuit element 170 can be electrically connected to the second circuit element 150 through the fifth contact 265 and the sixth contact 266. Figure 7BAs shown, when viewed along the direction extending from the main axis O, the third contact 263 and the fourth contact 264 are located diagonally opposite each other in the optical element drive mechanism 1000, and the fifth contact 265 and the sixth contact 266 are located diagonally opposite each other in the optical element drive mechanism 1000. It should be noted that the fifth contact 265 may be located in the first retaining wall 121, meaning that the second circuit element 150 may be at least partially buried and not exposed in the first retaining wall 121, thus protecting the second circuit element 150.

[0179] Figure 8 This is a schematic diagram of an optical element driving mechanism 1000 according to some embodiments. In some embodiments, the optical element driving mechanism 1000 may further include an optical unit 300 disposed on the optical element 400. The optical element 400 may be disposed in the movable portion 130, for example, fixed in a through hole of the movable portion 130, and may move together with the movable portion 130.

[0180] In some embodiments, the optical unit 300 may mainly include a base 310, a movable element 320, a driving element 330, and a connecting element 340. The base 310 may be fixed to the optical element 400. Since the optical element 400 is fixed in the movable part 130, the base 310 may be disposed in the movable part 130. The movable element 320 may be used to connect to the light control unit 350, such as a lens, aperture, shutter, or filter, and the movable element 320 may move relative to the base 310. The driving element 330 may be disposed on the base 310 and the movable element 320 to drive the movable element 320 to move relative to the base 310. In other words, the driving element 330 may also be used to drive the movable element 320 to move relative to the fixed part 510 and the movable part 130.

[0181] In some embodiments, the optical element 400 may include a lens barrel 410 and a lens 420. The lens barrel 410 may be made of plastic, while the lens 420 may be fixedly disposed on the lens barrel 410 and may be made of a light-transmitting material, such as transparent plastic or glass. A base 310 may be fixedly disposed on the lens barrel 410. In some embodiments, the base 310 may include a base surface 312, and the lens barrel 410 may have a lens barrel surface 412, wherein the base surface 312 and the lens barrel surface 412 may be parallel to each other and have a gap. Thus, additional adhesive elements (such as glue) may be added in this gap to fix the relative position of the lens barrel 410 and the base 310. It should be noted that the optical unit 300 is not directly connected to the fixing part 510.

[0182] In some embodiments, the driving element 330 of the optical unit 300 may be electrically connected to the fourth circuit element 170. For example, such as Figure 1A , Figure 1C , Figure 7AAs shown, the fourth circuit element 170 may include a seventh contact 267, which is visible in the outer frame 110 when viewed along the main axis O and does not overlap with the first top wall 111. Thus, the drive element 330 disposed above the outer frame 110 can be electrically connected to the seventh contact 267. It should be noted that the third circuit element 160 can be used to provide the energy required for the operation of the drive assembly 140, while the fourth circuit element 170 can be used to provide the energy required for the operation of the drive element 330. This allows for control of the drive assembly 140 and the drive element 330 through separate lines, avoiding interference between signals and thus enhancing the sensing effect.

[0183] In some embodiments, such as Figure 3A , Figure 6A As shown, the first circuit element 180 may also have external contacts 271, 272, 273, 274, and 275 for connecting to the external circuit 610. Figure 9 ). Figure 9 This is a schematic diagram of the circuits of the optical element driving mechanism 1000. External contacts 271, 272, and 273 can be connected to both the driving assembly 140 and the driving element 330 simultaneously, while external contact 274 can be electrically connected to the driving assembly 140 and is electrically independent of the optical unit 300 (e.g., the driving element 330). External contact 275 can be electrically connected to the driving element 330 and is electrically independent of the driving assembly 140.

[0184] For example, external contacts 271, 272, 273, and 274 can be electrically connected to an integrated circuit element 280, and then electrically connected to a drive assembly 140 via a third circuit element 160 to transmit signals to the drive assembly 140. In some embodiments, the integrated circuit element 280 can be integrated with the aforementioned sensing element 201, or can be located in a close proximity, such as on the same side of the optical element drive mechanism 1000, to achieve miniaturization.

[0185] External contacts 271, 272, 273, and 275 can be electrically connected to an integrated circuit element 360 via a fourth circuit element 170. The integrated circuit element 360 is then electrically connected to a driving element 330 to transmit signals to the driving element 330.

[0186] In some embodiments, the external circuit 610 may transmit a first signal to the external contact 274, the first signal including a varying voltage or current. The external circuit 610 may also transmit a second signal to the external contact 271 (or external contact 272, external contact 273), the second signal including a fixed voltage or current. Furthermore, the external circuit 610 may transmit a third signal to the external contact 275, the third signal including a varying voltage or current. Thus, by controlling the voltage or current at the external contacts 274 and 275, the drive assembly 140 or the drive element 330 can be controlled to avoid signal interference.

[0187] In some embodiments, if the center of gravity of the movable part 130 is not located at the center of the movable part 130, it may deflect after being mounted on the fixed part 510. To counteract this deflection, the third circuit element 160 (or the fourth circuit element 170) can be designed to deform after being mounted on the movable part 130, providing a force to the movable part 130 in a specific direction, thereby counteracting the aforementioned deflection caused by gravity, so that the final position of the movable part 130 can be as close as possible to the center of the optical element drive mechanism 1000, thereby improving the image quality. For example, the third circuit element 160 or the fourth circuit element 170 can be designed to be eccentric relative to the main axis O, for example, the main axis O does not pass through the center of the third circuit element 160 or the fourth circuit element 170.

[0188] For example, in some embodiments, such as Figure 3C As shown, the movable part 130 may have a first positioning structure 701, a third positioning structure 703, a fifth positioning structure 705, and a seventh positioning structure 707, while the base 120 of the fixed part 510 may have a second positioning structure 702, a fourth positioning structure 704, a sixth positioning structure 706, and an eighth positioning structure 708. The first positioning structure 701 may correspond to the second positioning structure 702, the third positioning structure 703 may correspond to the fourth positioning structure 704, the fifth positioning structure 705 may correspond to the sixth positioning structure 706, and the seventh positioning structure 707 may correspond to the eighth positioning structure 708, for example, they may be located at the same corner or side. It should be noted that although Figure 3C The embodiments shown depict each positioning structure located at a corner of the optical element drive mechanism 1000, but in some embodiments, each positioning structure may also be designed to be located on the side of the optical element drive mechanism 1000.

[0189] In some embodiments, the third circuit element 160 may have a first positioning part 711, a second positioning part 712, a third positioning part 713, a fourth positioning part 714, a fifth positioning part 715, a sixth positioning part 716, a seventh positioning part 717, and an eighth positioning part 718, which respectively correspond to the first positioning structure 701, the second positioning structure 702, the third positioning structure 703, the fourth positioning structure 704, the fifth positioning structure 705, the sixth positioning structure 706, the seventh positioning structure 707, and the eighth positioning structure 708.

[0190] For example, when viewed along the direction of the main axis O, the first positioning part 711, the second positioning part 712, the third positioning part 713, the fourth positioning part 714, the fifth positioning part 715, the sixth positioning part 716, the seventh positioning part 717, and the eighth positioning part 718 can respectively at least partially overlap with the first positioning structure 701, the second positioning structure 702, the third positioning structure 703, the fourth positioning structure 704, the fifth positioning structure 705, the sixth positioning structure 706, the seventh positioning structure 707, and the eighth positioning structure 708. The first positioning part 711, the second positioning part 712, the third positioning part 713, the fourth positioning part 714, the fifth positioning part 715, the sixth positioning part 716, the seventh positioning part 717, and the eighth positioning part 718 can be respectively provided in the first positioning structure 701, the second positioning structure 702, the third positioning structure 703, the fourth positioning structure 704, the fifth positioning structure 705, the sixth positioning structure 706, the seventh positioning structure 707, and the eighth positioning structure 708, so as to allow the third circuit element 160 to be movably connected to the movable part 130 and the fixed part 510.

[0191] In some embodiments, the first adhesive structure 721, the second adhesive structure 722, the third adhesive structure 723, the fourth adhesive structure 724, the fifth adhesive structure 725, the sixth adhesive structure 726, the seventh adhesive structure 727, and the eighth adhesive structure 728 may be respectively disposed on the first positioning structure 701, the second positioning structure 702, the third positioning structure 703, the fourth positioning structure 704, the fifth positioning structure 705, the sixth positioning structure 706, the seventh positioning structure 707, and the eighth positioning structure 708 for connecting the third circuit element 160, the movable part 130, and the base 120. The first adhesive structure 721, the second adhesive structure 722, the third adhesive structure 723, the fourth adhesive structure 724, the fifth adhesive structure 725, the sixth adhesive structure 726, the seventh adhesive structure 727, and the eighth adhesive structure 728 may be, for example, adhesives or other similar components.

[0192] Figure 10A , Figure 10B This is a schematic diagram showing the movable part 130 offset relative to the base 120 in a specific direction before the third circuit element 160 (or the fourth circuit element 170) is installed. Figure 10C This is a schematic diagram showing the positional relationship between the movable part 130 and the base 120 after the third circuit element 160 (or the fourth circuit element 170) is installed. For simplicity, the diagram is... Figure 10A , Figure 10B , Figure 10C The third circuit element 160 (or the fourth circuit element 170) is omitted. Figures 10A to 10C In this embodiment, the positioning structures are indicated in the corners. It should be noted that this is for illustrative purposes only, and the positions of the positioning structures can be changed as needed.

[0193] like Figure 10A As shown, the movable part 130 can translate or flip relative to the base 120 in the -Y direction. In this state, there is a first gap 731 between the first positioning structure 701 and the second positioning structure 702, a third gap 733 between the third positioning structure 703 and the fourth positioning structure 704, a fifth gap 735 between the fifth positioning structure 705 and the sixth positioning structure 706, and a seventh gap 737 between the seventh positioning structure 707 and the eighth positioning structure 708.

[0194] like Figure 10C As shown, after the third circuit element 160 is installed, the position of the movable part 130 is affected by the third circuit element 160 and moves to a position approximately at the center of the optical element driving mechanism 1000. At this time, there is a second spacing 732 between the first positioning structure 701 and the second positioning structure 702, a fourth spacing 734 between the third positioning structure 703 and the fourth positioning structure 704, a sixth spacing 736 between the fifth positioning structure 705 and the sixth positioning structure 706, and an eighth spacing 738 between the seventh positioning structure 707 and the eighth positioning structure 708.

[0195] In some embodiments, a first difference exists between the first spacing 731 and the second spacing 732, a second difference exists between the third spacing 733 and the fourth spacing 734, a third difference exists between the fifth spacing 735 and the sixth spacing 736, and a fourth difference exists between the seventh spacing 737 and the eighth spacing 738. It should be noted that in this embodiment, the first difference is less than the second difference, the first difference is less than the third difference, the first difference is equal to the fourth difference, and the second difference is equal to the third difference. This allows the use of a third circuit element 160 (or a fourth circuit element 170) to move the movable part 130 closer to the center of the optical element drive mechanism 1000 to enhance the imaging effect.

[0196] like Figure 10B As shown, the movable part 130 is positioned relative to the base 120 at the midpoint of a specific side (e.g., Figure 10BThe midpoint 741 is rotated. In this configuration, there is a first difference between the first spacing 731 and the second spacing 732, a second difference between the third spacing 733 and the fourth spacing 734, a third difference between the fifth spacing 735 and the sixth spacing 736, and a fourth difference between the seventh spacing 737 and the eighth spacing 738. The first difference is less than the second difference, the first difference is less than the third difference, the first difference is less than the fourth difference, the second difference is greater than the third difference, the second difference is greater than the fourth difference, and the third difference is greater than the fourth difference. This allows the use of a third circuit element 160 (or a fourth circuit element 170) to move the movable part 130 closer to the center of the optical element drive mechanism 1000, thereby enhancing the imaging effect. In some embodiments, the midpoint 741 may be located on a different side of the base 120 from the position sensing component 200 to avoid affecting the accuracy of the position sensing.

[0197] Figure 10D , Figure 10E This is a schematic diagram showing the movable part 130 offset relative to the base 120 in a specific direction before the third circuit element 160 (or the fourth circuit element 170) is installed. Figure 10F This is a schematic diagram showing the positional relationship between the movable part 130 and the base 120 after the third circuit element 160 (or the fourth circuit element 70) is installed. For simplicity, the diagram is... Figure 10D , Figure 10E , Figure 10F The third circuit element 160 (or the fourth circuit element 170) is omitted. Figures 10D to 10F In this embodiment, the positioning structures are indicated on the side. It should be noted that this is for illustrative purposes only, and the positions of the positioning structures can be changed as needed.

[0198] like Figure 10D As shown, the movable part 130 can translate or flip relative to the base 120 in the -Y direction. In this state, there is a first gap 731 between the first positioning structure 701 and the second positioning structure 702, a third gap 733 between the third positioning structure 703 and the fourth positioning structure 704, a fifth gap 735 between the fifth positioning structure 705 and the sixth positioning structure 706, and a seventh gap 737 between the seventh positioning structure 707 and the eighth positioning structure 708.

[0199] like Figure 10FAs shown, after the third circuit element 160 is installed, the position of the movable part 130 is affected by the third circuit element 160 and moves to a position approximately at the center of the optical element driving mechanism 1000. At this time, there is a second spacing 732 between the first positioning structure 701 and the second positioning structure 702, a fourth spacing 734 between the third positioning structure 703 and the fourth positioning structure 704, a sixth spacing 736 between the fifth positioning structure 705 and the sixth positioning structure 706, and an eighth spacing 738 between the seventh positioning structure 707 and the eighth positioning structure 708.

[0200] In some embodiments, a first difference exists between the first spacing 731 and the second spacing 732, a second difference exists between the third spacing 733 and the fourth spacing 734, a third difference exists between the fifth spacing 735 and the sixth spacing 736, and a fourth difference exists between the seventh spacing 737 and the eighth spacing 738. It should be noted that in this embodiment, the first difference is greater than the second difference, the first difference is equal to the third difference, the first difference is greater than the fourth difference, and the second difference is equal to the fourth difference. This allows the use of a third circuit element 160 (or a fourth circuit element 170) to move the movable part 130 closer to the center of the optical element drive mechanism 1000 to enhance the imaging effect.

[0201] like Figure 10E As shown, the movable part 130 is positioned relative to the base 120 at the midpoint of a specific side (e.g., Figure 10E The midpoint 741 is rotated. In this configuration, there is a first difference between the first spacing 731 and the second spacing 732, a second difference between the third spacing 733 and the fourth spacing 734, a third difference between the fifth spacing 735 and the sixth spacing 736, and a fourth difference between the seventh spacing 737 and the eighth spacing 738. The first difference is greater than the second difference, the first difference is less than the third difference, the first difference is greater than the fourth difference, the second difference is less than the third difference, the second difference is greater than the fourth difference, and the third difference is greater than the fourth difference. This allows the use of a third circuit element 160 (or a fourth circuit element 170) to move the movable part 130 closer to the center of the optical element drive mechanism 1000, thereby enhancing the imaging effect. In some embodiments, the midpoint 741 may be located on a different side from the position sensing component 200 to avoid affecting the accuracy of position sensing.

[0202] Although Figures 10A to 10FThe embodiments shown only illustrate translation or rotation, but this disclosure is not limited thereto. For example, the third circuit element 160 (or the fourth circuit element 170) can be designed to allow the movable part 130 to simultaneously translate and rotate relative to the base 120. For example, by changing the positions of the first positioning part 711, the second positioning part 712, the third positioning part 713, the fourth positioning part 714, the fifth positioning part 715, the sixth positioning part 716, the seventh positioning part 717, and the eighth positioning part 718, the initial position of the movable part 130 relative to the base 120 can be adjusted to improve image quality.

[0203] In summary, some embodiments of this disclosure provide an optical element driving mechanism, including a movable part, a fixed part, a driving assembly, and a circuit assembly. The movable part is used to connect to a first optical element. The movable part is movable relative to the fixed part. The driving assembly is used to drive the movable part to move relative to the fixed part. The circuit assembly is electrically connected to the driving assembly. The driving assembly is electrically connected to an external circuit via the circuit assembly. This improves the connection relationships between the circuits, avoids mutual interference between signals, and also achieves miniaturization.

[0204] The specific relative positions and size relationships of the components disclosed in this disclosure not only enable the optical component drive mechanism to achieve thinning in a specific direction and overall miniaturization, 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-stage anti-shake system to greatly improve the anti-shake effect.
