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 towards 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify the elements of the claims does not imply or represent any prior ordinal number of 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.

[0123] 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.

[0124] This disclosure provides an optical element driving mechanism for driving optical elements to move. For example, Figure 1A This is a schematic diagram of the optical element drive mechanism 1000A. Figure 1B This is an exploded view of the optical element drive mechanism 1000A. Figure 1C This is a top view of the optical element drive mechanism 1000A. 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 shown by line segment BB Figure 1F This is a top view of some components of the 1000A optical element drive mechanism.

[0125] like Figures 1A to 1F As shown, the optical element driving mechanism 1000A mainly includes a fixed part 1100A (including an outer frame 1110A and a base 1120A) arranged along the main axis 1900A, a first movable part 1210A, a second movable part 1220A, a driving assembly 1300A (including a first magnetic element 1311A, a second magnetic element 1312A, a third magnetic element 1313A, a coil assembly 1320A, and a third coil 1323A), a first intermediate element 1410A, a second intermediate element 1420A, a third intermediate element 1430A, a first circuit element 1511A, and a second circuit element 1512A, for carrying the first optical element 1610A to move.

[0126] In some embodiments, the first optical element 1610A may be, for example, a lens, a mirror, a prism, a reflective polished surface, an optical coating, a beam splitter, an aperture, a liquid lens, an image sensor, a camera module, a ranging module, etc. It should be noted that the definition of optical element herein is not limited to elements related to visible light; elements related to invisible light (e.g., infrared light, ultraviolet light) may also be included in this disclosure.

[0127] In some embodiments, the outer frame 1110A and the base 1120A can be combined to form the housing of the optical element driving mechanism 1000A, and other components of the optical element driving mechanism 1000A can be disposed within the housing formed by the outer frame 1110A and the base 1120A to protect other components. For example, the base 1120A can be fixedly connected to the outer frame 1110A. It should be understood that the outer frame 1110A and the base 1120A 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 1900A passing through the first optical element 1610A, and the base opening corresponds to the photosensitive element (not shown) outside the optical element driving mechanism 1000A. Accordingly, the first optical element 1610A disposed in the optical element driving mechanism 1000A can focus with the photosensitive element in the direction (Z direction) extending from the main axis 1900A.

[0128] In some embodiments, a first movable portion 1210A may be disposed in a second movable portion 1220A, and the first movable portion 1210A is used to connect to the first optical element 1610A. The second movable portion 1220A may be disposed in a fixed portion 1100A. In some embodiments, the first movable portion 1210A may move relative to the second movable portion 1220A, and the second movable portion 1220A may move relative to the fixed portion 1100A, and the movement directions of the first movable portion 1210A and the second movable portion 1220A may be different from each other, so as to allow the first optical element 1610A to move in different directions relative to the fixed portion 1100A. For example, the first movable portion 1210A may have a through hole, and the first optical element 1610A may be fixed in this through hole to move together with the first movable portion 1210A.

[0129] In some embodiments, the cover 1130A may be fixedly disposed on the second movable part 1220A for movement together with the second movable part 1220A, and a receiving space may be formed in the cover 1130A and the second movable part 1220A, where other components, such as the first movable part 1210A and the first optical element 1610A, may be disposed to protect each component. Figure 1F As shown, when viewed along the main axis 1900A, the first movable part 1210A and the second movable part 1220A at least partially overlap with the cover 1130A, and the first movable part 1210A and the second movable part 1220A at least partially protrude from the cover 1130A.

[0130] In some embodiments, the drive assembly 1300A can be used to drive the first movable part 1210A and the second movable part 1220A to move relative to the fixed part 1100A. For example, such as Figure 1D , Figure 1EAs shown, the coil assembly 1320A may include a first coil 1321A, a second coil 1322A, and a first body 1324A, wherein the first coil 1321A and the second coil 1322A may be embedded in the first body 1324A, and the first body 1324A may, for example, be made of a polymer material to protect the first coil 1321A and the second coil 1322A.

[0131] In some embodiments, such as Figure 1D As shown, the first magnetic element 1311A can be disposed on the first movable part 1210A, and the first coil 1321A can be disposed on the base 1120A. When the first coil 1321A is energized, the first coil 1321A interacts with the magnetic field of the first magnetic element 1311A and generates an electromagnetic force to drive the first movable part 1210A and the first optical element 1610A to move relative to the second movable part 1220A and the fixed part 1100A.

[0132] In addition, such as Figure 1E As shown, the second magnetic element 1312A can be disposed on the second movable part 1220A, and the second coil 1322A can be disposed on the base 1120A. When the aforementioned second coil 1322A is energized, the second coil 1322A interacts with the magnetic field of the second magnetic element 1312A, generating an electromagnetic driving force to drive the second movable part 1220A to move relative to the fixed part 1100A, thereby achieving the effect of autofocus (AF) or optical image stabilization (OIS). In some embodiments, the positions of the first magnetic element 1311A and the first coil 1321A can be interchanged, or the positions of the second magnetic element 1312A and the second coil 1322A can be interchanged, depending on the design requirements.

[0133] In some embodiments, such as Figure 1D , Figure 1EAs shown, the first magnetic element 1331A may correspond to the first magnetic element 1311A, for example, they may be arranged on the Z-axis, while the second magnetic element 1332A may correspond to the second magnetic element 1312A, for example, they may be arranged on the Z-axis, and the third magnetic element 1333A may correspond to the third magnetic element 1313A, for example, they may be arranged on the Y-axis. The first magnetic element 1331A, the second magnetic element 1332A, and the third magnetic element 1333A may include magnetically permeable materials, such as metals. Thus, the magnetic lines of force of the first magnetic element 1311A, the second magnetic element 1312A, and the third magnetic element 1313A can be modified to enhance the driving effect. In some embodiments, the first magnetic element 1331A, the second magnetic element 1332A, and the third magnetic element 1333A may be disposed on the base 1120A.

[0134] In some embodiments, such as Figure 1D , Figure 1E As shown, the first intermediate element 1410A can be disposed between the first movable portion 1210A and the second movable portion 1220A to movably connect the first movable portion 1210A and the second movable portion 1220A. For example, the first intermediate element 1410A can be disposed between the first movable portion 1210A and the second movable portion 1220A by means of frictional contact.

[0135] In some embodiments, the buffer element 1530A may be disposed on the outer frame 1110A and partially exposed thereout to act as a buffer between the outer frame 1110A and other components (such as the second optical element mentioned in subsequent embodiments) to prevent direct collision. In some embodiments, the buffer element 1530A may comprise a soft material, such as rubber.

[0136] Figure 2A This is a top view of the first intermediate element 1410A. Figure 2B This is a top view of the first active section 1210A. Figure 2C This is a top view of the second active section 1220A. Figure 2D This is a top view of the first intermediate element 1410A, the first movable part 1210A, and the second movable part 1220A. (See attached image.) Figures 2A to 2D As shown, when viewed along the main axis 1900A, the main body 1411A may have an L-shaped shape, for example, it may be provided on two sides of the first movable part 1210A or the second movable part 1220A.

[0137] In some embodiments, the contact unit 1412A may have a spherical or hemispherical arc shape, and may be located on the body 1411A to reduce the contact area between the first intermediate element 1410A and the first movable part 1210A and the second movable part 1220A, thereby reducing the friction between the first intermediate element 1410A and the first movable part 1210A and the second movable part 1220A, so as to allow the first intermediate element 1410A to movably connect the first movable part 1210A and the second movable part 1220A.

[0138] In some embodiments, the first intermediate element 1410A can be used to guide the first movable portion 1210A to move relative to the second movable portion 1220A in a specific direction. For example, such as Figure 2B As shown, the first recessed structure 1211A of the first movable portion 1210A may have a groove structure extending in the X direction, and the contact unit 1412A may be partially disposed in the first recessed structure 1211A, thereby allowing the first intermediate element 1410A to move relative to the first movable portion 1210A in the X direction. Furthermore, as... Figure 2C As shown, the second recessed structure 1221A of the second movable part 1220A may have a groove structure extending in the Y direction, and the contact unit 1412A may be partially disposed in the second recessed structure 1221A, thereby allowing the first intermediate element 1410A to move in the Y direction relative to the second movable part 1220A.

[0139] like Figure 2D As shown, when viewed along the main axis 1900A, the contact unit 1412A can simultaneously overlap at least partially with both the first recessed structure 1211A and the second recessed structure 1221A. For example, a portion of the contact unit 1412A can be disposed in the first recessed structure 1211A, while another portion can be disposed in the second recessed structure 1221A. Furthermore, the surface of the contact unit 1412A can have a spherical or arcuate structure to reduce friction when in contact with the first and second recessed structures 1211A and 1221A. In other words, the first movable part 1210A can move relative to the second movable part 1220A in the XY plane via the first intermediate element 1410A, thereby achieving optical image stabilization. Moreover, since the first intermediate element 1410A can be disposed in the XY plane, the size of the optical element drive mechanism 1000A in the Z-axis can be reduced, achieving miniaturization.

[0140] It should be noted that since the aforementioned contact unit 1412A is held by the first movable part 1210A and the second movable part 1220A, the movable direction of the first intermediate element 1410A, the first movable part 1210A and the second movable part 1220A is restricted. As a result, when the first movable part 1210A moves relative to the second movable part 1220A, they will not flip or rotate with each other, thereby reducing the difficulty of driving and improving the accuracy of driving.

[0141] Figure 3A This is a top view of some components of the 1000A optical element drive mechanism. Figure 3B This is a side view of some components of the optical element drive mechanism 1000A, which mainly shows the coil assembly 1320A and components near the first circuit element 1511A. Figure 3A , Figure 3B As shown, the first circuit element 1511A may have a first surface 1513A, and a first solder portion 1931A and a second solder portion 1932A may be provided on the first surface 1513A. The first solder portion 1931A may correspond to the first coil 1321A, and the second solder portion 1932A may correspond to the first electronic element 1541A. In some embodiments, the first coil 1321A may be electrically connected to the first solder portion 1931A via a first electrical connection element 1543A, and the first electronic element 1541A may be electrically connected to the second solder portion 1932A via a second electrical connection element 1544A. In some embodiments, the first electrical connection element 1543A and the second electrical connection element 1544A may include conductive materials, such as conductive adhesive, solder, etc. The second electronic element 1542A may be disposed within the second coil 1322A, and its configuration may be similar to the configuration relationship between the first electronic element 1541A and the first coil 1321A described below.

[0142] In some embodiments, the aforementioned first electronic component 1541A and second electronic component 1542A may include a Hall sensor, a magnetoresistance effect sensor (MRSensor), a giant magnetoresistance effect sensor (GMR Sensor), a tunneling magnetoresistance effect sensor (TMR Sensor), or a fluxgate sensor.

[0143] In some embodiments, such as Figure 3AAs shown, when viewed along a direction perpendicular to the first surface 1513A (e.g., the Z direction), the area of ​​the first weld portion 1931A can be larger than the area of ​​the second weld portion 1932A. Furthermore, as... Figure 3B As shown, in a direction perpendicular to the first surface 1513A (e.g., the X direction), the maximum size 1924A of the first electrical connection element 1543A may differ from the maximum size 1925A of the second electrical connection element 1544A, for example, it may be larger than the maximum size 1925A of the second electrical connection element 1544A. In some embodiments, a first bonding element 1545A may be provided between the first circuit element 1511A and the first coil 1321A to fix the relative positions of the first circuit element 1511A and the first coil 1321A. In some embodiments, the first bonding element 1545A may directly contact the first electrical connection element 1543A and the second electrical connection element 1544A. The first bonding element 1545A may include a non-conductive bonding material.

[0144] In some embodiments, such as Figure 3A As shown, the first coil 1321A may include a first receiving space 1911A, a second receiving space 1912A, and a connecting space 1913A. The first receiving space 1911A can be connected to the second receiving space 1912A via the connecting space 1913A. In some embodiments, a first electronic component 1541A may be disposed in the first receiving space 1911A. Furthermore, when viewed along the direction (Z direction) of the winding axis 1903A of the first coil 1321A, the area of ​​the first receiving space 1911A is different from the area of ​​the second receiving space 1912A. For example, the area of ​​the first receiving space 1911A may be larger than the area of ​​the second receiving space 1912A to allow the first electronic component 1541A to be disposed in a larger space.

[0145] In some embodiments, the first axis 1901A and the second axis 1902A may be perpendicular to the winding axis 1903A, and the first axis 1901A and the second axis 1902A may be perpendicular to each other. The first receiving space 1911A, the connecting space 1913A, and the second receiving space 1912A may be arranged sequentially along the first axis 1901A, for example, along the X direction, and in the extension direction (Y direction) of the second axis 1902A, the minimum size 1921A of the first receiving space 1911A and the minimum size 1922A of the second receiving space 1912A may be larger than the minimum size 1923A of the connecting space 1913A. This reduces the space occupied by the connecting space 1913A, allowing the first coil 1321A to have a dumbbell-shaped structure, thus achieving miniaturization of the overall structure. The second coil 1322A may also have a structure similar to the first coil 1321A, which will not be described further here.

[0146] Figure 3CThis is a schematic diagram of some components of the 1000A optical element drive mechanism. For example... Figure 3C As shown, the base 1120A may include a first circuit unit 1521A, a second circuit unit 1522A, and a third circuit unit 1523A. The first circuit unit 1521A can be connected to a first circuit element 1511A, the second circuit unit 1522A can be connected to the first circuit unit 1521A, and the third circuit unit 1523A can be connected to the second circuit unit 1522A. Thus, the electrical signal of the first circuit element 1511A can sequentially communicate with other external devices through the first circuit unit 1521A, the second circuit unit 1522A, and the third circuit unit 1523A. In some embodiments, the base 1120A may include a non-conductive material, while the first circuit unit 1521A, the second circuit unit 1522A, and the third circuit unit 1523A may include conductive materials, such as metal.

[0147] In some embodiments, the first circuit unit 1521A may be partially embedded in the second movable portion 1220A and partially exposed in the second movable portion 1220A. The second circuit unit 1522A is disposed between the outer frame 1110A and the base 1120A, and may be exposed in the base 1120A and the second movable portion 1220A to correspond to the second optical element (not shown in this embodiment, but may correspond to the second optical elements 1620B, 1620C, 1620D, 1620E in subsequent embodiments).

[0148] In some embodiments, in the direction in which the main shaft 1900A extends, the second circuit unit 1522A may be disposed between the cover 1130A and the outer frame 1110A. The third circuit unit 1523A may be partially embedded in the base 1120A and partially exposed in the base 1120A. That is, the first circuit unit 1521A may be movable relative to the third circuit unit 1523A.

[0149] In some embodiments, such as Figure 3C As shown, the base 1120A may include an upper surface 1121A and a lower surface 1122A, which face opposite directions and are perpendicular to the Z-axis. The third circuit unit 1523A may be partially exposed on the upper surface 1121A and the lower surface 1122A of the base.

[0150] Figure 1F , Figure 3CAs shown, the second intermediate element 1420A and the third intermediate element 1430A may have an elongated shape, extend parallel to the main shaft 1900A, and may be disposed between the second movable part 1220A and the fixed part 1100A, for example, between the second movable part 1220A and the base 1120A, to movably connect the fixed part 1100A and the second movable part 1220A, so as to allow the second movable part 1220A to move relative to the fixed part 1100A on the Z-axis, thereby achieving the function of autofocus.

[0151] For example, the second intermediate element 1420A and the third intermediate element 1430A can be disposed on the second movable part 1220A by frictional contact and fixed on the fixed part 1100A (e.g., the base 1120A). In some embodiments, the second intermediate element 1420A and the third intermediate element 1430A can also be fixed on the second movable part 1220A and disposed on the fixed part 1100A (e.g., the base 1120A) by frictional contact, depending on design requirements.

[0152] It should be noted that, when the first optical element 1610A of this disclosure moves, if it needs to move in the XY plane, it can be movably connected to the first movable part 1210A and the second movable part 1220A through the first intermediate element 1410A, thereby allowing the first optical element 1610A to move in the XY plane relative to the fixed part 1100A along with the first movable part 1210A and the second movable part 1220A, to achieve the function of optical image stabilization. When the first optical element 1610A needs to move along the Z direction, it can be movably connected to the second movable part 1220A and the fixed part 1100A through the second intermediate element 1420A and the third intermediate element 1430A, thereby allowing the optical element to move in the Z-axis relative to the fixed part 1100A along with the first movable part 1210A and the second movable part 1220A, to achieve the function of autofocus. By using two different mechanisms to achieve optical image stabilization and autofocus separately, it is ensured that optical image stabilization and autofocus do not interfere with each other, thereby improving the accuracy of driving and sensing.

[0153] Although the foregoing embodiments electrically connect the second optical element to the outside world through a first circuit unit 1521A embedded in the second movable part 1220A, a second circuit unit 1522A exposed in the base 1120A and the second movable part 1220A, and a third circuit unit 1523A embedded in the base 1120A, this disclosure is not limited thereto. For example, Figure 4A This is a schematic diagram of the optical element drive mechanism 1000B. Figure 4B This is an exploded view of the optical element drive mechanism 1000B. Figure 4CThis is a top view of the optical element drive mechanism 1000B. Figure 4D It is along Figure 4C The cross-sectional view shown by line segment CC. Figure 4E It is along Figure 4C The cross-sectional view shown by line segment DD. Figure 4F This is a schematic diagram of some components of the 1000B optical element drive mechanism.

[0154] like Figures 4A to 4F As shown, the optical element driving mechanism 1000B mainly includes a fixed part 1100B (including an outer frame 1110B and a base 1120B) arranged along the main axis 1900B, a first movable part 1210B, a second movable part 1220B, a driving assembly 1300B (including a first magnetic element 1311B, a second magnetic element 1312B, a third magnetic element 1313B, a coil assembly 1320B (including a first coil 1321B, a second coil 1322B, and a third coil 1323B), a first intermediate element 1410B, a second intermediate element 1420B, a third intermediate element 1430B, a first circuit element 1511B, a second circuit element 1512B, and a buffer element 1530B, used to support the first optical element 1610B for movement. These components can be respectively similar to the fixing part 1100A (including the outer frame 1110A and the base 1120A), the first movable part 1210A, the second movable part 1220A, the driving assembly 1300A (including the first magnetic element 1311A, the second magnetic element 1312A, the third magnetic element 1313A, the coil assembly 1320A, and the third coil 1323A), the first intermediate element 1410A, the second intermediate element 1420A, the third intermediate element 1430A, the first circuit element 1511A, the second circuit element 1512A, and the buffer element 1530A of the optical element driving mechanism 1000A, and will not be described in detail here.

[0155] like Figures 4D to 4F As shown, the optical element driving mechanism 1000B may further include a first circuit unit 1521B. The first circuit unit 1521B may be disposed on the first movable part 1210B and the first optical element 1610B, and may be disposed between the outer frame 1110B and the base 1120B, so as to move together with the first optical element 1610B. The second optical element 1620B may be disposed on the first circuit unit 1521B, so as to move together with the first optical element 1610B.

[0156] In some embodiments, the first circuit unit 1521B may be disposed between the first optical element 1610B and the second optical element 1620B. In some embodiments, the second optical element 1620B may include, for example, an aperture, shutter, or other optical element, and may be electrically connected to the first circuit unit 1521B. The first circuit unit 1521B is then electrically connected to the second circuit element 1512B, so that the second optical element 1620B can be electrically connected to an external device through the first circuit unit 1521B and the second circuit element 1512B. In some embodiments, the second circuit element 1512B may be fixed to the base 1120B. In some embodiments, the first circuit unit 1521B and the second circuit element 1512B may include, for example, a printed circuit board (PCB) or a flexible circuit board (FPC).

[0157] In some embodiments, such as Figure 4F As shown, the base 1120B may include an adjacent upper base surface 1121B, a first base side surface 1123B, and a second base side surface 1124B, which are perpendicular to the Z-axis, X-axis, and Y-axis, respectively, meaning their normal vectors are parallel to the Z-axis, X-axis, and Y-axis, respectively. A first circuit unit 1521B may be disposed on the upper base surface 1121B, while a second circuit element 1512B may be disposed on the upper base surface 1121B, the first base side surface 1123B, and the second base side surface 1124B. In the direction extending from the main axis 1900B (Z-axis), the first circuit unit 1521B and the second circuit element 1512B at least partially overlap.

[0158] Although the foregoing embodiments electrically connect the second optical element 1620B to an external device via a circuit board assembly, this disclosure is not limited thereto. For example, Figure 5A This is a schematic diagram of the optical element drive mechanism 1000C. Figure 5B This is an exploded view of the optical element drive mechanism 1000C. Figure 5C This is a top view of the optical element drive mechanism 1000C. Figure 5D It is along Figure 5C The cross-sectional view shown by line segment EE Figure 5E It is along Figure 5C The cross-sectional view shown by line segment FF Figure 5F This is a schematic diagram of some components of the 1000C optical element drive mechanism.

[0159] like Figures 5A to 5FAs shown, the optical element driving mechanism 1000C mainly includes a fixed part 1100C (including an outer frame 1110C and a base 1120C) arranged along the main axis 1900C, a first movable part 1210C, a second movable part 1220C, a driving assembly 1300C (including a first magnetic element 1311C, a second magnetic element 1312C, a third magnetic element 1313C, a coil assembly 1320C (including a first coil 1321C, a second coil 1322C, and a third coil 1323C), a third magnetic conductive element 1333C, a first intermediate element 1410C, a second intermediate element 1420C, a third intermediate element 1430C, a first circuit element 1511C, and a buffer element 1530C, for carrying the first optical element 1610C to move. These components can be similar to the fixing part 1100A (including the outer frame 1110A and the base 1120A), the first movable part 1210A, the second movable part 1220A, the driving assembly 1300A (including the first magnetic element 1311A, the second magnetic element 1312A, the third magnetic element 1313A, the coil assembly 1320A, and the third coil 1323A), the third magnetic conductive element 1333A, the first intermediate element 1410A, the second intermediate element 1420A, the third intermediate element 1430A, the first circuit element 1511A, and the buffer element 1530A of the optical element driving mechanism 1000A, respectively, and will not be described in detail here.

[0160] like Figures 5D to 5F As shown, the second optical element 1620C can be disposed on the first optical element 1610C and the first movable part 1210C, so as to move together with the movement of the first optical element 1610C and the first movable part 1210C. In addition, the optical element driving mechanism 1000C may also include a first circuit unit 1521C, a second circuit unit 1522C, and a third circuit unit 1523C, disposed between the outer frame 1110C and the base 1120C. The first circuit unit 1521C may be exposed above the first circuit element 1511C and may be electrically connected to the first circuit element 1511C. Then, the first circuit element 1511C may be electrically connected to the second circuit unit 1522C. Then, the second circuit unit 1522C may be exposed above the first circuit element 1511C and may be electrically connected to the third circuit unit 1523C. In some embodiments, the first circuit unit 1521C, the second circuit unit 1522C, and the third circuit unit 1523C may be made of metal, and the first circuit element 1511C may, for example, be a printed circuit board or a flexible circuit board. Thus, the second optical element 1620C can be electrically connected to an external device sequentially through the first circuit unit 1521C, the first circuit element 1511C, the second circuit unit 1522C, and the third circuit unit 1523C.

[0161] In some embodiments, such as Figure 5F As shown, the second circuit unit 1522C can be disposed on the first circuit element 1511C and the base 1120C, for example, disposed on the upper surface 1121C of the base, to movably connect the second movable part 1220C and the base 1120C. In some embodiments, the third circuit unit 1523C can be partially embedded in the base 1120C and partially exposed on the base 1120C, for example, exposed on the upper surface 1121C and the lower surface 1122C of the base, so as to directly contact the second circuit unit 1522C at the upper surface 1121C of the base. In some embodiments, the upper surface 1121C and the lower surface 1122C of the base can face opposite directions, for example, they can face the +Z and -Z directions respectively.

[0162] In some embodiments, a first circuit unit 1521D made of printed circuit board or flexible circuit board material may be used to replace the aforementioned first circuit unit 1521C made of metal material. For example, Figure 6A This is an exploded view of the 1000D optical element drive mechanism. Figure 6B This is a top view of the 1000D optical element drive mechanism. Figure 6C It is along Figure 6B The cross-sectional view shown by line segment GG Figure 6D It is along Figure 6B The cross-sectional view shown by line segment HH Figure 6E This is a schematic diagram of some components of the 1000D optical element drive mechanism.

[0163] like Figures 6A to 6EAs shown, the optical element driving mechanism 1000D mainly includes a fixed part 1100D (including an outer frame 1110D and a base 1120D) arranged along the main axis 1900D, a first movable part 1210D, a second movable part 1220D, a driving assembly 1300D (including a first magnetic element 1311D, a second magnetic element 1312D, a third magnetic element 1313D, a coil assembly 1320D (including a first coil 1321D, a second coil 1322D, and a third coil 1323D), a third magnetic conductive element 1333D, a first intermediate element 1410D, a second intermediate element 1420D, a third intermediate element 1430D, a first circuit element 1511D, and a buffer element 1530D, for carrying the first optical element 1610D to move.

[0164] like Figures 6C to 6E As shown, the second optical element 1620D can be disposed on the first optical element 1610D and the first movable part 1210D, so as to move together with the movement of the first optical element 1610D and the first movable part 1210D. In addition, the optical element driving mechanism 1000D may also include a first circuit unit 1521D, a second circuit unit 1522D, and a third circuit unit 1523D, disposed between the outer frame 1110D and the base 1120D. The first circuit unit 1521D is exposed above the first circuit element 1511D and can be electrically connected to the first circuit element 1511D. Then, the first circuit element 1511D can be electrically connected to the second circuit unit 1522D. Then, the second circuit unit 1522D is exposed above the first circuit element 1511D and can be electrically connected to the third circuit unit 1523D.

In some embodiments, the upper surface 1121D and the lower surface 1122D of the base can face opposite directions, for example, they can face the +Z and -Z directions respectively.

[0167] Although the circuit units used for electrically connecting the second optical element in the foregoing embodiments are disposed in the fixing part, that is, between the outer frame and the base, this disclosure is not limited thereto. For example, Figure 7A This is a schematic diagram of the optical element drive mechanism 1000E. Figure 7B This is an exploded view of the optical element drive mechanism 1000E. Figure 7C This is a top view of the optical element drive mechanism 1000E. Figure 7D It is along Figure 7C The cross-sectional view shown by line segment II, Figure 7E It is along Figure 7C The cross-sectional view shown by line segment JJ. Figure 8A , Figure 8B This is a schematic diagram of some components of the 1000E optical element drive mechanism when viewed from different directions.

[0168] like Figures 7A to 8BAs shown, the optical element driving mechanism 1000E mainly includes a fixed part 1100E (including an outer frame 1110E and a base 1120E) arranged along the main axis 1900E, a first movable part 1210E, a second movable part 1220E, a driving assembly 1300E (including a first magnetic element 1311E, a second magnetic element 1312E, a third magnetic element 1313E, a coil assembly 1320E (including a first coil 1321E, a second coil 1322E, and a third coil 1323E), a third magnetic conductive element 1333E, a first intermediate element 1410E, a second intermediate element 1420E, a third intermediate element 1430E, a first circuit element 1511E, and a buffer element 1530E, for carrying the first optical element 1610E to move.

In some embodiments, the cover 1130E protrudes from the outer frame 1110E. Furthermore, in the direction perpendicular to the main shaft 1900E, as... Figure 7D as well as Figure 7E As shown, the maximum size of the cover 1130E can be larger than the maximum size of the outer frame 1110E or the base 1120E.

[0170] In some embodiments, such as Figure 7A , Figure 7C As shown, the cover 1130E may have a polygonal shape, with multiple first protrusions 1131E at each corner and multiple second protrusions 1132E on the sides. The first protrusions 1131E and the second protrusions 1132E may extend along the main axis 1900E, for example, extending in the +Z direction.

[0171] The optical element driving mechanism 1000E may further include a first circuit unit 1521E. The first circuit unit 1521E may include a first contact portion 1531E disposed on the first protrusion 1131E, a second contact portion 1532E disposed below the second optical element 1620E, and a string portion 1533E connecting the first contact portion 1531E and the second contact portion 1532E. Furthermore, a plurality of elastic elements 1534E may be disposed on the second protrusion 1132E to movably connect the second optical element 1620E and the cover 1130E. For example, the optical element driving mechanism 1000E may include two elastic elements 1534E, and these two elastic elements 1534E may be disposed on opposite sides of the optical element driving mechanism 1000E.

[0172] In some embodiments, the first circuit unit 1521E may be exposed above the fixing portion 1100E, for example, in the direction (Z direction) in which the main shaft 1900E extends, and the cover 1130E may be disposed between the first circuit unit 1521E and the outer frame 1110E. Figure 7C As shown, when viewed along the main axis 1900, the second optical element 1620E and the second contact portion 1532E at least partially overlap.

[0173] In some embodiments, such as Figure 8A , Figure 8B As shown, the second optical element 1620E is electrically connected to the second contact portion 1532E, and the second contact portion 1532E is then electrically connected to the first contact portion 1531E via the string portion 1533E. Next, the first contact portion 1531E can be electrically connected to an external device via a second circuit unit 1522E embedded in the cover body 1130E. In some embodiments, the cover body 1130E may further include an extension portion 1133E extending in the opposite direction to the first protrusion 1131E and the second protrusion 1132E, for example, extending in the -Z direction, and the second circuit unit 1522E may be partially disposed within the extension portion 1133E and partially exposed therefrom to protect the second circuit unit 1522E.

[0174] It should be noted that one end of the second circuit unit 1522E can be connected to the first contact portion 1531E located at different corners of the cover 1130E, while the other end can protrude from the extension 1133E located on the same side of the cover 1130E. Furthermore, as... Figure 7C As shown, when viewed along the main axis 1900E, the second contact portion 1532E and the extension portion 1133E can be provided on the same side 1134E of the cover 1130E to facilitate subsequent electrical connection with other external devices.

[0175] In some embodiments, the coil assembly 1320E (including a first coil 1321E and a second coil 1322E) and the third coil 1323E can be electrically connected to the first circuit element 1511E. Then, the first circuit element 1511E can sequentially connect the coil assembly 1320E and the third coil 1323E to other external devices via the third circuit unit 1523E and the fourth circuit unit 1524E, thereby controlling the coil assembly 1320E and the third coil 1323E. The third circuit unit 1523E and the fourth circuit unit 1524E can be disposed in the fixing portion 1100E, and the fourth circuit unit 1524E can be partially exposed in the fixing portion 1100E. Furthermore, the fourth circuit unit 1524E and the second circuit unit 1522E can be disposed on different sides of the optical element driving mechanism 1000E, thereby avoiding interference between the electrical signals.

[0176] In summary, the present disclosure provides an optical element driving mechanism, including a first movable part, a fixed part, a driving assembly, and a first intermediate element. The first movable part is used to connect to a first optical element. The first movable part is movable relative to the fixed part. The driving assembly is used to drive the first movable part to move relative to the fixed part. The first intermediate element is movably connected to the first movable part. Therefore, effects such as autofocus, optical image stabilization, and zoom can be achieved, and miniaturization can also be realized.

[0177] The specific relative positions and size relationships of the components disclosed in this disclosure not only enable the 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.
