Description

TECHNICAL FIELD

[0001] The present disclosure relates to an optical element driving mechanism. BACKGROUND

[0002] With the development of technology, nowadays many electronic devices (e.g. smart phones or digital cameras) have the function of taking pictures or videos. These electronic devices are increasingly popular and are developing towards the direction of convenience and thinness, to provide users with more choices.

[0003] The aforementioned electronic devices with the function of taking pictures or videos usually have an optical element driving mechanism to drive an optical element (e.g. a lens) to move along an optical axis, thereby achieving the functions of auto focus (AF) or optical image stabilization (OIS).

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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] Moreover, in some embodiments of the present disclosure, the terms related to joining, connecting, such as "connected", "interconnected" and the like, unless specifically defined, can refer to two structures being in direct contact, or can also refer to two structures not being in direct contact, with other structures being disposed between the two structures. Also, the terms related to joining, connecting can also include cases where both structures can be movable, or both structures can be fixed.

[0114] Embodiments of the present disclosure provide an optical element driving mechanism to drive an optical element to move. For example, FIG. 1A is a schematic diagram of an optical element driving mechanism 1000. FIG. 1B is an exploded view of the optical element driving mechanism 1000. FIG. 1C is a top view of the optical element driving mechanism 1000. FIG. 2A is a cross-sectional view taken along a line segment A-A of FIG. 1C . FIG. 2B is a cross-sectional view taken along a line segment B-B of FIG. 1C . FIG. 2C is a cross-sectional view taken along a line segment C-C of FIG. 1C .

[0115] As shown in FIGS. 1A-2C , the optical element driving mechanism 1000 can mainly include a fixed part 1100 (including an outer frame 1110, a base 1120), a first movable part 1210, a second movable part 1220, a driving assembly 1300, a conductive assembly 1400, a support assembly 1500, a circuit element 1600, an intermediate assembly 1700 arranged along an optical axis 1900, to drive an optical element (not shown) to move. The optical axis 1900 can pass through the center (e.g. geometric center) of the optical element, and extend in the Z-axis.

[0116] In some embodiments, the aforementioned optical element can be disposed in the second movable part 1220, for example, can be fixed in the second movable part 1220 by locking, bonding, clamping, etc. The aforementioned optical element can 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 the optical element here is not limited to elements related to visible light, and elements related to invisible light (such as infrared light, ultraviolet light) can also be included in the present disclosure.

[0117] In some embodiments, the outer frame 1110 and the base 1120 of the fixed portion 1100 can be combined to form a housing of the optical element driving mechanism 1000, and other elements of the optical element driving mechanism 1000 can be disposed in the housing formed by the outer frame 1110 and the base 1120 to protect the other elements. For example, the base 1120 can be fixedly connected to the outer frame 1110. In some embodiments, additional circuitry can be embedded in the base 1120 to allow elements in the optical element driving mechanism 1000 to be electrically connected to other elements.

[0118] In some embodiments, the first movable portion 1210 and the second movable portion 1220 can be disposed in the fixed portion 1100 and can move relative to the fixed portion 1100. That is, the first movable portion 1210 and the second movable portion 1220 can be movably connected to the fixed portion 1100. In addition, the second movable portion 1220 can be disposed in the first movable portion 1210, and the first movable portion 1210 can also move relative to the second movable portion 1220.

[0119] In some embodiments, the driving assembly 1300 can be used to drive the first movable portion 1210 and the second movable portion 1220 to move relative to the fixed portion 1100 to achieve the effects of auto focus (AF) or optical image stabilization (OIS). In some embodiments, the first movable portion 1210 can move along the X-axis and the Y-axis, and the second movable portion 1220 can move along the Z-axis. The driving assembly 1300 can drive the first movable portion 1210 to change from a first state to a second state relative to the fixed portion 1100, such as moving from an initial position to a specific position, and the first state and the second state are both included in the movement range of the first movable portion 1210, such as moving to different positions or rotating through different angles.

[0120] In some embodiments, the conductive component 1400 may include a metallic material and may be disposed between the first movable portion 1210 and the second movable portion 1220 and the fixed portion 1100, so that the first movable portion 1210 and the second movable portion 1220 are movably connected to the fixed portion 1100, thereby allowing the first movable portion 1210 and the second movable portion 1220, as well as the optical element disposed on the second movable portion 1220, to move relative to the fixed portion 1100. In addition, the conductive component 1400 may also be electrically connected to the circuitry embedded in the base 1120 to electrically connect to other electronic components in the optical element drive mechanism 1000. In some embodiments, the conductive component 1400 may be electrically connected to an external module (not shown, such as an aperture, shutter, or other optically related module), and this external module may be disposed on the second movable portion 1220, so that it moves together with the second movable portion 1220 and the optical element.

[0121] Specifically, in some embodiments, such as FIG. 2C As shown, the conductive component 1400 may include a first conductive portion 1401 and a second conductive portion 1402. The first conductive portion 1401 may have a plate-like shape and extend in the XY plane. The second conductive portion 1402 may have an elongated shape and extend along the Z-axis. The first conductive portion 1401 can be electrically connected to an external module (not shown) disposed on the second movable portion 1220. The second conductive portion 1402 can then be electrically connected to the first conductive portion 1401. Additional circuitry may be disposed in the base 1120, and this circuitry may be electrically connected to the first conductive portion 1401. During assembly, the first conductive portion 1401 and the second conductive portion 1402 may be joined using soldering or laser welding, and the second conductive portion 1402 may also be joined to the circuitry in the base 1120. In other words, the external module located on the second active part 1220 can be electrically connected to the circuit in the base 1120 via the conductive component 1400 to provide an electrical signal to control the external module.

[0122] In some embodiments, a support component 1500 may be disposed between the fixed portion 1100 and the first movable portion 1210 to allow the first movable portion 1210 to move relative to the fixed portion 1100 via the support component 1500. Furthermore, an intermediate component 1700 may be disposed between the first movable portion 1210 and the second movable portion 1220 to allow the second movable portion 1220 to move relative to the first movable portion 1210 via the intermediate component 1700.

[0123] In some embodiments, the circuit element 1600, for example, can be a Printed Circuit Board (PCB) that can be disposed on the fixed portion 1100 and the first movable portion 1210, for example, can be fixed on the fixed portion 1100 and the first movable portion 1210 by an adhesive manner, to electrically connect other elements (for example, the driving assembly 1300) in the optical element driving mechanism 1000 and external devices, so as to provide electrical signals to these elements. Thus, the movement of the first movable portion 1210 and the second movable portion 1220 on the X, Y and Z axes can be controlled, and the functions of auto-focusing (AF) and optical image stabilization (OIS) can be realized. In some embodiments, the driving assembly 1300 can be fixed on the circuit element 1600 by an adhesive manner.

[0124] FIG. 3A is a top view of some elements of the optical element driving mechanism 1000, in which some elements are omitted to better show the positional relationship of other elements. As shown in FIG. 2A 、 FIG. 2B 、 FIG. 3A The driving assembly 1300 can include a first coil 1301, a second coil 1302, a third coil 1303, a fourth coil 1304, a fifth coil 1305, a first magnetic element 1311, a second magnetic element 1312, and a third magnetic element 1313, wherein the first coil 1301, the second coil 1302, and the third coil 1303 can be disposed on the circuit element 1600 and disposed on the fixed portion 1100 (for example, disposed on the base 1120) through the circuit element 1600. The first magnetic element 1311, the second magnetic element 1312, and the third magnetic element 1313 can be disposed above the first movable portion 1210, and the fourth coil 1304 and the fifth coil 1305 can be disposed above the second movable portion 1220.

[0125] The first magnetic element 1311, the second magnetic element 1312, and the third magnetic element 1313 can be magnets, for example, can be multi-pole magnets. The first coil 1301, the second coil 1302, the third coil 1303, the fourth coil 1304, and the fifth coil 1305 can include a single coil, or can include a coil assembly in which multiple coils are embedded in a circuit board to provide magnetic fields in different directions.

[0126] In some embodiments, the first coil 1301 and the fourth coil 1304 can correspond to the first magnetic element 1311, for example, the first magnetic element 1311 can be disposed between the first coil 1301 and the fourth coil 1304, and the first coil 1301, the first magnetic element 1311, and the fourth coil 1304 can be arranged in sequence on the X-axis. Thus, when the first coil 1301 and the fourth coil 1304 are energized, the first coil 1301 and the fourth coil 1304 can generate electromagnetic driving forces in different directions with the first magnetic element 1311, respectively, to drive the first movable part 1210 to move relative to the fixed part 1100 and drive the second movable part 1220 to move relative to the first movable part 1210, respectively. For example, the first coil 1301 and the first magnetic element 1311 can generate a driving force parallel to the X-axis to drive the first movable part 1210 to move on the X-axis relative to the fixed part 1100. The fourth coil 1304 and the first magnetic element 1311 can generate a driving force parallel to the Z-axis to drive the second movable part 1220 to move on the Z-axis relative to the first movable part 1210. In some embodiments, the first coil 1301 can have a plate-like shape, and its normal vector can be parallel to the X-axis.

[0127] Similarly, in some embodiments, the second coil 1302 and the fifth coil 1305 can correspond to the second magnetic element 1312, for example, the second magnetic element 1312 can be disposed between the second coil 1302 and the fifth coil 1305, and the second coil 1302, the second magnetic element 1312, and the fifth coil 1305 can be arranged in sequence on the X-axis. Thus, when the second coil 1302 and the fifth coil 1305 are energized, the second coil 1302 and the fifth coil 1305 can generate electromagnetic driving forces in different directions with the second magnetic element 1312, respectively, to drive the first movable part 1210 to move relative to the fixed part 1100 and drive the second movable part 1220 to move relative to the first movable part 1210, respectively. For example, the second coil 1302 and the second magnetic element 1312 can generate a driving force parallel to the X-axis to drive the first movable part 1210 to move on the X-axis relative to the fixed part 1100. The fifth coil 1305 and the second magnetic element 1312 can generate a driving force parallel to the Z-axis to drive the second movable part 1220 to move on the Z-axis relative to the first movable part 1210. In some embodiments, the second coil 1302 can have a plate-like shape, and its normal vector can be parallel to the X-axis.

[0128] In some embodiments, the third coil 1303 may correspond to the third magnetic element 1313, for example, they may be arranged on the Z-axis and at least partially overlap. Thus, when the third coil 1303 is energized, the third coil 1303 and the third magnetic element 1313 may generate an electromagnetic driving force on the Y-axis to drive the first movable part 1210 to move relative to the fixed part 1100 on the Y-axis.

[0129] In some embodiments, such as FIG. 2A as well as FIG. 3A As shown, multiple positioning elements 1610 can be provided in the third coil 1303, for example, they can be fixedly disposed on the circuit element 1600 to define the position of the third coil 1303. For example, the third coil 1303 can be wound on two positioning elements 1610 simultaneously. In some embodiments, the second sensing element 1722 can be disposed in the third coil 1303, for example, disposed between the two positioning elements 1610, to protect the second sensing element 1722 and obtain better sensing effect.

[0130] By providing the drive assembly 1300, the optical element disposed in the second movable part 1220 can be driven to move along the X, Y, and Z axes to achieve autofocus and optical image stabilization. Furthermore, since the first coil 1301 and the fourth coil 1304, used to drive different directions, share the first magnetic element 1311, and the second coil 1302 and the fifth coil 1305 also share the second magnetic element 1312, the number of required magnetic elements can be reduced, thereby lowering costs and achieving miniaturization. In some embodiments, the drive assembly 1300 may also include a piezoelectric element, shape memory alloy, or other drive element.

[0131] In some embodiments, such as FIG. 2C , FIG. 3AAs shown, the intermediate assembly 1700 can include a first intermediate unit 1701, a second intermediate unit 1702, a first auxiliary magnetic element 1711, and a second auxiliary magnetic element 1712. The first intermediate unit 1701 and the second intermediate unit 1702 can be fixedly disposed on one of the first movable portion 1210 and the second movable portion 1220, and can move relative to the other, for example, by frictional contact. For example, the first intermediate unit 1701 and the second intermediate unit 1702 can be fixedly disposed on the first movable portion 1210, and can be disposed on the second movable portion 1220 by frictional contact. In some embodiments, the first intermediate unit 1701 and the second intermediate unit 1702 can also be fixedly disposed on the second movable portion 1220, and can be disposed on the first movable portion 1210 by frictional contact, depending on design requirements. In some embodiments, the first intermediate unit 1701 and the second intermediate unit 1702 can extend along the Z-axis to control the moving direction of the second movable portion 1220 relative to the first movable portion 1210.

[0132] In some embodiments, the first intermediate unit 1701 and the second intermediate unit 1702 can have a magnetic conductive material, and the first auxiliary magnetic element 1711 and the second auxiliary magnetic element 1712 can be disposed on the second movable portion 1220, and correspond to the first intermediate unit 1701 and the second intermediate unit 1702, respectively. The second movable portion 1220 is partially disposed between the first intermediate unit 1701 and the first auxiliary magnetic element 1711, and is partially disposed between the second intermediate unit 1702 and the second auxiliary magnetic element 1712. The first intermediate unit 1701 and the second intermediate unit 1702 can generate magnetic attraction with the first auxiliary magnetic element 1711 and the second auxiliary magnetic element 1712, respectively, to exert a force on the first intermediate unit 1701 and the second intermediate unit 1702 towards the second movable portion 1220 when the drive assembly 1300 is not powered, so that the first intermediate unit 1701 and the second intermediate unit 1702 can be disposed on the second movable portion 1220 by frictional contact, to fix the position of the second movable portion 1220 relative to the first movable portion 1210 when not powered.

[0133] Then, when the drive assembly 1300 is powered, if the force exerted by the drive assembly 1300 on the second movable portion 1220 in the Z-axis is greater than the maximum static friction between the first intermediate unit 1701 and the second intermediate unit 1702 and the second movable portion 1220, the second movable portion 1220 can move relative to the first intermediate unit 1701 and the second intermediate unit 1702, that is, relative to the first movable portion 1210. Thus, the optical element disposed on the second movable portion 1220 can maintain focus at a specific position to improve the optical quality of the resulting image.

[0134] FIG. 3B is a top view of some elements of the optical element driving mechanism 1000, in which some elements are omitted to better show the positional relationship of other elements. FIG. 4A is a sectional view taken along the line segment D-D of FIG. 3B . FIG. 4B is an enlarged view of the region 1930 of FIG. 4A in some embodiments. As shown in FIG. 3B , FIG. 4A , and FIG. 4B , the support assembly 1500 can include a first intermediate element 1501, a first body 1511, a first reinforcing element 1541, a second reinforcing element 1542, a first support element 1551, and a second support element 1552. In some embodiments, the first body 1511 can be integrally formed with the first movable part 1210, for example, can be a part of the first movable part 1210, the second surface 1522 can be formed on the first body 1511, the first support element 1551 can be formed on the first surface 1521 of the base 1120 and include a first recessed structure 1553, and the second support element 1552 can be formed on the second surface 1522 of the first movable part 1210 and include a second recessed structure 1554.

[0135] In some embodiments, the first intermediate element 1501 can be at least partially disposed in the first recessed structure 1553 and the second recessed structure 1554. The first intermediate element 1501 can be fixedly disposed in the first recessed structure 1553 and movably disposed in the second recessed structure 1554. In some embodiments, the first recessed structure 1553 and the second recessed structure 1554 are different from each other. For example, as shown in FIG. 3B , the first recessed structure 1553 can have a circular shape when viewed along the Z-axis, and as shown in FIG. 4B , can have a first corresponding surface 1531 and a second corresponding surface 1532. The first corresponding surface 1531 and the second corresponding surface 1532 can correspond to the first intermediate element 1501, for example, can directly contact the first intermediate element 1501, or can have lubricating oil or glue therebetween, and the first corresponding surface 1531 and the second corresponding surface 1532 are not parallel to each other. In addition, the base 1120 can also have a positioning portion 1533 extending from the first surface 1521 towards the Z-axis, which surrounds part of the first intermediate element 1501 to position the position of the first intermediate element 1501.

[0136] In some embodiments, the second recessed structure 1554 can have an elongated structure when viewed along the direction of the second surface 1522 (e.g., along the Z-axis), which can extend along the first imaginary line 1904, e.g., along the Y-axis. When viewed along the first rotation axis 1903, the first imaginary line 1904 and the line 1905 connecting the center 1910 of the optical element and the first rotation axis 1903 are not perpendicular to each other. In addition, in some embodiments, the first reinforcing element 1541 and the second reinforcing element 1542 can be disposed in the second recessed structure 1554, and can have a fourth corresponding surface 1534 and a fifth corresponding surface 1535, respectively. The fourth corresponding surface 1534 and the fifth corresponding surface 1535 can correspond to the first intermediate element 1501, e.g., can directly contact the first intermediate element 1501, or can have lubricating oil or glue therebetween, and the fourth corresponding surface 1534 and the fifth corresponding surface 1535 are not parallel to each other. In addition, neither the fourth corresponding surface 1534 nor the fifth corresponding surface 1535 is parallel to or perpendicular to the first corresponding surface 1531 and the second corresponding surface 1532.

[0137] In some embodiments, the hardness (e.g., Vickers hardness) of the first body 1511 is different from the hardness of the first reinforcing element 1541 and the second reinforcing element 1542, e.g., the hardness (e.g., Vickers hardness) of the first body 1511 is less than the hardness of the first reinforcing element 1541 or the second reinforcing element 1542. In some embodiments, the material of the first body 1511 can include, e.g., ceramic, plastic, rubber, or other polymers, while the material of the first reinforcing element 1541 and the second reinforcing element 1542 can include, e.g., metal, to reinforce the structural strength of the contact position with the first intermediate element 1501 by the first reinforcing element 1541 and the second reinforcing element 1542, thereby improving the durability of the optical element driving mechanism 1000.

[0138] In some embodiments, the support assembly 1500 can further include a second intermediate element 1502 and a third intermediate element 1503, which are disposed between the first movable part 1210 and the base 1120, and can at least partially overlap the first movable part 1210 and the base 1120 when viewed along the optical axis 1900. As shown, the first movable part 1210 can further include a second receiving space 1122 and a third receiving space 1123, and the second intermediate element 1502 is at least partially disposed in the second receiving space 1122, and the third intermediate element 1503 is at least partially disposed in the third receiving space 1123. FIG. 2C

[0139] In some embodiments, as shown, the first movable part 1210 can further include a second receiving space 1122 and a third receiving space 1123, and the second intermediate element 1502 is at least partially disposed in the second receiving space 1122, and the third intermediate element 1503 is at least partially disposed in the third receiving space 1123. FIG. 3B ​As shown, the second intermediate element 1502 may have a spherical structure, for example, and may have a size 1921 (e.g., diameter). In the direction extending along the X-axis, the second receiving space 1122 may have a size 1922, and in the direction extending along the Y-axis, the second receiving space 1122 may have a size 1923, with both sizes 1922 and 1923 being larger than size 1921. That is, when viewed along the optical axis 1900, either size 1922 or size 1923 of the second receiving space 1122 may be larger than size 1921 of the second intermediate element 1502, allowing the second intermediate element 1502 to move freely within the second receiving space 1122 without being restricted in position by it. Similarly, when viewed along the optical axis 1900, the size of the third receiving space 1123 may be larger than the size of the third intermediate element 1503, allowing the third intermediate element 1503 to move freely within the third receiving space 1123.

[0140] In some embodiments, such as FIG. 2C As shown, a third reinforcing element 1543 and a fourth reinforcing element 1544 can be provided on the second body 1121 of the base 1120, corresponding to the second intermediate element 1502 and the third intermediate element 1503 respectively. For example, they can directly contact the second intermediate element 1502 and the third intermediate element 1503, or there can be lubricating oil or glue between them. The third reinforcing element 1543 and the fourth reinforcing element 1544 can be partially embedded in the second body 1121 and partially exposed in the second body 1121. The hardness (e.g., Vickers hardness) of the second body 1121 is less than the hardness of the third reinforcing element 1543 and the fourth reinforcing element 1544. Therefore, by providing the third reinforcing element 1543 and the fourth reinforcing element 1544 in the second body 1121, the mechanical strength at the contact point between the base 1120 and the second intermediate element 1502 and the third intermediate element 1503 can be strengthened, thereby improving the durability of the optical element drive mechanism 1000.

[0141] Since the second intermediate element 1502 and the third intermediate element 1503 are free to move in the second receiving space 1122 and the third receiving space 1123 respectively, and are free to move relative to the third reinforcing element 1543 and the fourth reinforcing element 1544 respectively, the second intermediate element 1502 and the third intermediate element 1503 do not serve to restrict the movement direction of the first movable part 1210 in the XY plane. In other words, with this design, the first movable part 1210 can rotate relative to the fixed part 1100 about the first rotation axis 1903, and can move along the first imaginary line 1904 in the Y axis. When the angle of rotation of the first movable part 1210 is small (e.g. less than ±1 degree), the displacement of the optical element disposed in the first movable part 1210 can be approximated as movement along the X axis. Thus, this design can allow the position of the optical element to be controlled in the X axis or the Y axis to achieve the function of optical image stabilization.

[0142] In some embodiments, the first rotation axis 1903 does not overlap the center 1910 of the optical element when viewed along the first rotation axis 1903. The center 1910 of the optical element can be defined, for example, as the center of the opening 1221 of the second movable part 1220 when the opening 1221 is circular, when viewed along the optical axis 1900 (when viewed along the Z axis). The first rotation axis 1903 does not overlap the center 1910 of the optical element means that the first rotation axis 1903 does not pass through the center 1910 of the optical element. In some embodiments, the first rotation axis 1903 is parallel to the optical axis 1900, for example, extending parallel to the Z axis. In some embodiments, the first rotation axis 1903 does not pass through the optical element, for example, does not pass through the opening 1221 of the second movable part 1220 used to dispose the optical element.

[0143] In some embodiments, the support assembly 1500 can further include a force applying element 1560, which can be disposed in the base 1120 and spaced apart from the first intermediate element 1501. In the Z axis, the force applying element 1560 can at least partially overlap the first reinforcing element 1541 and the second reinforcing element 1542. In some embodiments, the force applying element 1560 can include a magnet, and the first reinforcing element 1541 and the second reinforcing element 1542 can include a magnetically conductive metal to generate a magnetic attraction force with the force applying element 1560, thereby generating a stabilizing force to keep the first movable part 1210 and the fixed part 1100 close to the first intermediate element 1501, thereby preventing the first intermediate element 1501 from falling out of the first recessed structure 1553 and the second recessed structure 1554. The force applying element 1560 can have a force applying element surface 1561 facing the first intermediate element 1501, the first reinforcing element 1541 and the second reinforcing element 1542, for example, can have a normal vector parallel to the Z axis, and the force applying element surface 1561 is neither perpendicular nor parallel to the fourth corresponding surface 1534 and the fifth corresponding surface 1535.

[0144] Although the foregoing embodiment designs the first recessed structure 1553 to have a cylindrical groove, the present disclosure is not limited thereto. For example, FIG. 4C is another embodiment in which FIG. 4A is a zoomed-in view of the region 1930 of FIG. 4D is a schematic view of the base 1120 and the first intermediate element 1501. As FIG. 4C and FIG. 4D illustrated, the first support element 1551a in this embodiment can have a first recessed structure 1553a, such as a groove having a tetrahedron shape, and including a first corresponding surface 1531a, a second corresponding surface 1532a, and a third corresponding surface 1533a. The first intermediate element 1501 can correspond to the first corresponding surface 1531a, the second corresponding surface 1532a, and the third corresponding surface 1533a, such as the first corresponding surface 1531a, the second corresponding surface 1532a, and the third corresponding surface 1533a can directly contact the first intermediate element 1501, or can have lubricating oil or glue therebetween. The first corresponding surface 1531a, the second corresponding surface 1532a, and the third corresponding surface 1533a are neither parallel nor perpendicular to each other, and are neither parallel nor perpendicular to a fourth corresponding surface 1534 and a fifth corresponding surface 1535.

[0145] In other words, the number of surfaces of the first recessed structure 1553a corresponding to the first intermediate element 1501 can be different from the number of surfaces of the second recessed structure 1554 corresponding to the first intermediate element 1501, such as the number of surfaces of the first recessed structure 1553a corresponding to the first intermediate element 1501 (3 surfaces) can be greater than the number of surfaces of the second recessed structure 1554 corresponding to the first intermediate element 1501 (2 surfaces). By providing three surfaces (the first corresponding surface 1531a, the second corresponding surface 1532a, and the third corresponding surface 1533a) of the first recessed structure 1553a corresponding to the first intermediate element 1501, the position of the first intermediate element 1501 can be defined by three contact points, so as to reduce the influence of tolerances during production.

[0146] In some embodiments, as FIG. 2A , FIG. 3B illustrated, the optical element driving mechanism 1000 can further include a sensing assembly 1720 for sensing the movement of the first movable part 1210, which can include a first sensing element 1721 and a second sensing element 1722 for sensing the movement of the first movable part 1210 along the first direction and the second direction, respectively. FIGS. 6A-6Cmotion of the first axis 1901 (e.g., X-axis) and the second axis 1902 (e.g., Y-axis) of the first movable portion 1210. In some embodiments, the first sensing element 1721 and the second sensing element 1722 can include, for example, a Hall 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.

[0147] FIG. 5A and FIG. 5B are respectively schematic diagrams of the positional relationship of some elements when the first movable portion 1210 is in the first state and the second state relative to the fixed portion 1100 when the first recessed structure 1553 is cylindrical. As shown in FIG. 5A and FIG. 5B when viewed along the direction perpendicular to the first surface 1521 (e.g., Z-direction), the center 1504 of the first intermediate element 1501 overlaps with the first rotation axis 1903 in FIG. 5A (the first state), and the center 1504 of the first intermediate element 1501 does not overlap with the first rotation axis 1903 in FIG. 5B (the second state).

[0148] That is, the distance between the center 1504 of the first intermediate element 1501 and the center of the first recessed structure 1553 (e.g., the intersection of the first rotation axis 1903 and the first imaginary line 1904) when the first movable portion 1210 is in the first state is different from the distance between the center 1504 of the first intermediate element 1501 and the center of the first recessed structure 1553 when the first movable portion 1210 is in the second state. In other words, when the first movable portion 1210 moves relative to the fixed portion 1100, the first intermediate element 1501 can be displaced or rotated in the first recessed structure 1553.

[0149] FIG. 5Cis a schematic diagram of the positional relationship of some elements when the first movable part 1210 is in the first state and the second state relative to the fixed part 1100 when the first recessed structure 1553a of the triangle is used. It should be noted that at this time, in either the first state or the second state, that is, when the first movable part 1210 moves relative to the fixed part 1100 (for example, moves along the X-axis or the Y-axis), when the first movable part 1210 is in the first state, the distance between the center 1504 of the first intermediate element 1501 and the center of the first recessed structure 1553a is the same as the distance between the center 1504 of the first intermediate element 1501 and the center of the first recessed structure 1553a when the first movable part 1210 is in the second state, for example, the center 1504 of the first intermediate element 1501 and the center of the first recessed structure 1553a in the first state and the second state can overlap with each other, or can have a fixed relative position. In other words, when the first movable part 1210 moves relative to the fixed part 1100, the first intermediate element 1501 does not displace in the first recessed structure 1553a, but only rotates.

[0150] 1553a. In other words, when the first movable part 1210 moves relative to the fixed part 1100, the first intermediate element 1501 does not displace in the first recessed structure 1553a, but only rotates.

[0151] FIG. 6A 、 FIG. 6B 、 FIG. 6C is a top view of some elements of the optical element driving mechanism 1000, mainly showing a schematic diagram when the first movable part 1210 moves relative to the fixed part 1100. At FIG. 6A , the first movable part 1210 is in a preset position relative to the fixed part 1100. At FIG. 6B , the first movable part 1210 rotates relative to the fixed part 1100 about the first rotation axis 1903 in the clockwise direction. When the angle of rotation of the first movable part 1210 is very small (for example, less than ±1 degree), at this time the displacement of the optical element arranged therein can be approximated as movement along the X-axis. At FIG. 6C , the first movable part 1210 moves along the Y-axis. As shown in FIG. 3B , when viewed along the first rotation axis 1903, the first axis 1901 is not perpendicular to the line 1905 connecting the center 1910 of the optical element and the first rotation axis 1903.

[0152] FIG. 7A 、 FIG. 7B 、 FIG. 7C 、 FIG. 7D shows a schematic diagram of the output sensing signal value when the first movable part 1210 displaces relative to the fixed part 1100, wherein FIG. 7A shows the value output by the first sensing element 1721 when the first movable part 1210 moves from the preset position 1961 to the first position 1962 along the first axis 1901, and FIG. 7BThe figure shows the value output by the second sensing element 1722 when it moves from the preset position 1961 to the first position 1962 along the first axis 1901. FIG. 7C The figure shows the value output by the first sensing element 1721 when the first movable part 1210 moves from the preset position 1961 to the second position 1963 along the second axis. FIG. 7D The figure shows the value output by the second sensing element 1722 when it moves from the preset position 1961 to the second position 1963 along the second axis 1902.

[0153] like FIG. 7A as well as FIG. 7B As shown, when the first movable part 1210 is at the preset position 1961, the first sensing element 1721 outputs a first initial value 1941, and the second sensing element 1722 outputs a second initial value 1942. Then, when the first movable part 1210 moves from the preset position 1961 to the first position 1962 along the first axis 1901, the first sensing element 1721 outputs a first sensing value 1951, and the second sensing element 1722 outputs a second sensing value 1952. Furthermore, as... FIG. 7C as well as FIG. 7D As shown, when the first movable part 1210 moves from the preset position 1961 to the second position 1963 along the second axis 1902, the first sensing element 1721 outputs the third sensing value 1953, and the second sensing element 1722 outputs the fourth sensing value 1954.

[0154] It should be noted that the degree of movement of the first position 1962 relative to the preset position 1961 is the same as the degree of movement of the second position 1963 relative to the preset position 1961. For example, if the first position 1962 moves by 50% of the maximum travel (first limit range) on the first axis 1901 relative to the preset position 1961, then the second position 1963 also moves by 50% of the maximum travel (second limit range) on the second axis 1902 relative to the preset position 1961. The preset position 1961 may be located at the center of the first limit range and the second limit range. In some embodiments, the absolute value of the difference between the first position 1962 and the preset position 1961 is at least greater than one-quarter of the first limit range.

[0155] However, at this time, the absolute distances of the first movable part 1210 moved on the first axis 1901 and on the second axis 1902 are different. Therefore, the values output by the first sensing element 1721 and the second sensing element 1722 are not necessarily the same at the same stroke of the first axis 1901 and the second axis 1902. For example, the absolute value of the difference between the second sensing value 1952 and the second initial value 1942 is different from the absolute value of the difference between the third sensing value 1953 and the first initial value 1941. For example, the absolute value of the difference between the second sensing value 1952 and the second initial value 1942 can be greater than the absolute value of the difference between the third sensing value 1953 and the first initial value 1941. In addition, the absolute value of the difference between the first sensing value 1951 and the second sensing value 1952 is different from the absolute value of the difference between the third sensing value 1953 and the fourth sensing value 1954. For example, the absolute value of the difference between the first sensing value 1951 and the second sensing value 1952 can be less than the absolute value of the difference between the third sensing value 1953 and the fourth sensing value 1954.

[0156] In summary, the optical element driving mechanism provided by the embodiments of the present disclosure includes a first movable part, a fixed part, and a driving assembly. The first movable part is used to connect an 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 driving assembly can drive the first movable part to change from a first state to a second state, and the first state and the second state are both included in the movement range. Thus, the effects of automatic focusing, optical anti-shake, zooming, and the like can be achieved, and miniaturization can also be achieved.

[0157] The special relative positions and size relationships of the elements disclosed in the present disclosure not only make the driving mechanism thin in a specific direction and small in size as a whole, but also further improve the optical quality (such as the shooting quality or the depth sensing accuracy) of the system by matching different optical modules. Furthermore, multiple anti-shake systems are achieved by using the optical modules to greatly improve the effect of anti-shake.

[0158] Although the present disclosure has been disclosed with reference to the embodiments above, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the disclosure. Moreover, the scope of the disclosure is not intended to be limited to the particular embodiments described in the specification. Rather, the scope of the disclosure includes any embodiments that have structural modifications, but perform substantially the same function or achieve substantially the same result. Accordingly, what is to be understood is that the present disclosure encompasses all modifications, alternatives and equivalents falling within the scope of the claims.
