Abstract
Description
Technical Field
[0001] The present disclosure relates to an optical element driving mechanism. Background Art
[0002] With the development of technology, many electronic devices (such as smart phones or digital cameras) now have the function of taking photos or recording videos. These electronic devices are becoming more and more popular and are developing in the direction of convenient and lightweight designs to provide users with more choices.
[0003] Electronic devices with camera or video recording capabilities typically incorporate an optical element drive mechanism to drive an optical element (such as a lens) along the optical axis, thereby achieving autofocus (AF) or optical image stabilization (OIS). Light passes through the optical element to form an image on a photosensitive element.

[0180] The following discloses many different implementation methods or examples to implement the different features of the subject matter provided. The following describes specific embodiments of the components and their arrangements to illustrate the present disclosure. Of course, these embodiments are only for illustration and should not be used to limit the scope of the present disclosure. For example, when the specification mentions that a first feature component is formed on a second feature component, it may include an embodiment in which the first feature component and the second feature component are in direct contact. It may also include an embodiment in which there are other features between the first feature component and the second feature component. In other words, the first feature component and the second feature component are not in direct contact.
[0181] In addition, repeated numbers or labels may be used in different embodiments. These repetitions are only for the purpose of simply and clearly describing the present disclosure and do not represent a specific relationship between the different embodiments and / or structures discussed. In addition, in the present disclosure, forming, connecting and / or coupling to another feature component on top of another feature component may include embodiments in which the feature components are formed to be in direct contact, and may also include embodiments in which additional feature components can be formed to be inserted into the above-mentioned feature components, so that the above-mentioned feature components may not be in direct contact. In addition, spatially related words such as "vertical", "above", "up", "below", "bottom" and similar words (such as "downwardly", "upwardly", etc.) may be used. These spatially related words are for the purpose of facilitating the description of the relationship between one (some) element or feature and another (some) element or feature in the diagram. These spatially related words are intended to cover different directions of the device including the feature.
[0182] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meanings as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with the background or context of the relevant technology and this disclosure and should not be interpreted in an idealized or overly formal manner unless otherwise defined herein.
[0183] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify claim elements does not in itself imply or represent that the claimed element has any previous ordinal number, nor does it represent the order of one claimed element and another claimed element, or the order in the manufacturing method. The use of multiple ordinal numbers is only used to clearly distinguish a claimed element with a certain name from another claimed element with the same name.
[0184] Furthermore, in some embodiments of the present disclosure, terms such as "connected" and "interconnected," unless otherwise specified, may refer to two structures being in direct contact, or to two structures not being in direct contact, with another structure positioned between them. Furthermore, such terms may include situations where both structures are movable or both structures are fixed.
[0185] The present disclosure provides an optical element driving mechanism for driving an optical element to move. For example, Figure 1A is a schematic diagram of the optical element driving mechanism 1000, Figure 1B is an exploded view of the optical element driving mechanism 1000. Figure 1C FIG is a top view of the optical element driving mechanism 1000. Figures 1A to 1C As shown, the optical element driving mechanism 1000 may mainly include a fixing portion 1100 , a movable component 1200 , a circuit component 1300 , a driving component 1400 , and a connecting component 1500 arranged along a main axis 1900 .
[0186] In some embodiments, the fixed portion 1100 may include an outer frame 1110 and a base 1120, which may be combined to form a housing for the optical element driving mechanism 1000, for example, arranged along the main axis 1900 to house and protect other components. The movable assembly 1200 may include a first movable portion 1210 and a second movable portion 1220, which may be movable relative to the fixed portion 1100.

[0187] In some embodiments, the optical element may be, for example, a lens, a mirror, a prism, a reflective polished surface, an optical coating, a beamsplitter, 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 here is not limited to elements related to visible light, and elements related to invisible light (such as infrared light, ultraviolet light) may also be included in the present invention.
[0188] In some embodiments, the circuit assembly 1300 may include a first circuit element 1310 and a second circuit element 1330 to electrically connect various components within the optical element driving mechanism 1000 and other external devices. It may also connect the fixed portion 1100 and the movable component 1200, allowing the first movable component 1210 to be movably connected to the second movable component 1220 via the circuit assembly 1300.

Figure 2C yes Figure 2B The enlarged view of the R1 part, Figure 2D It is along Figure 1C The cross-sectional view shown by the CC line segment, Figure 2E It is along Figure 1C The cross-sectional view is shown along the DD line.
[0190] like Figure 2A 、 Figure 2BAs shown, coil assembly 1410 may include a first coil 1411, a second coil 1412, a third coil 1413, a fourth coil 1414, and a fifth coil 1415, and magnetic assembly 1420 may include a first magnetic element 1421, a second magnetic element 1422, and a third magnetic element 1423. In some embodiments, first coil 1411 and second coil 1412 may be disposed on first movable portion 1210, while third coil 1413, fourth coil 1414, and fifth coil 1415 may be embedded in second circuit element 1330. In some embodiments, main axis 1900 may be parallel to first axis 1911, first coil 1411 and second coil 1412 may be aligned along third axis 1913, and second axis 1912 may be perpendicular to first axis 1911 and third axis 1913.
[0191] In some embodiments, the first coil 1411 may correspond to the first magnetic element 1421, the second coil 1412 may correspond to the third magnetic element 1423, the third coil 1413 may correspond to the first magnetic element 1421, the fourth coil 1414 may correspond to the third magnetic element 1423, and the fifth coil 1415 may correspond to the second magnetic element 1422. In some embodiments, on the third axis 1913, the first magnetic element 1421 is located between the second movable portion 1220 and the first coil 1411, and the third magnetic element 1423 is located between the second movable portion 1220 and the second coil 1412. On the first axis 1911, the first magnetic element 1421 is located between the second movable portion 1220 and the third coil 1413, the second magnetic element 1422 is located between the second movable portion 1220 and the fourth coil 1414, and the third magnetic element 1423 is located between the second movable portion 1220 and the fifth coil 1415.
[0192] Thus, the first movable part 1210 can be pushed to move relative to the second movable part 1220 through the first magnetic element 1421, the third magnetic element 1423, the first coil 1411, and the second coil 1412, and the second movable part 1220 can also be pushed to move relative to the fixed part 1100 through the first magnetic element 1421, the second magnetic element 1422, the third magnetic element 1423, the third coil 1413, the fourth coil 1414, and the fifth coil 1415 to achieve functions such as auto focus (AF) and optical image stabilization (OIS).
[0193] Figure 3A is a schematic diagram of some components of the optical element driving mechanism 1000, Figure 3B yes Figure 3A A partial enlarged view of Figure 3C 12 is a partial enlarged view of the second movable portion 1220. Figure 2C 、 Figure 3A 、 Figure 3B As shown, the optical element driving mechanism 1000 may include a first buffer element 1521 disposed on the second movable portion 1220 . Figure 3D Schematic diagram of the first buffer element 1521. Figure 2C 、 Figure 3D As shown, the first buffer element 1521 may have an elongated structure and may include a main body 1530, a recessed structure 1531, a through hole 1532, and a contact portion 1533. The contact portion 1533 is connected to the main body 1530, and the recessed structure 1531 and the through hole 1532 are located between the main body 1530 and the contact portion 1533. In some embodiments, as shown in FIG. Figure 2C As shown, on the first axis 1911 , the main body 1530 has a first height 1971 , and the contact portion 1533 has a second height 1972 . The first height 1971 may be different from the second height 1972 , for example, the first height 1971 may be greater than the second height 1972 .
[0194] In some embodiments, as Figure 3B As shown, the contact portion 1533 can directly contact the first setting portion 1225 of the second movable portion 1220. In some embodiments, the first cushioning element 1521 can be fixedly set on the first setting portion 1225 by the coupling element 1540, as shown in FIG. Figure 2C 、 Figure 3B As shown, the engaging element 1540 can directly contact the recessed structure 1531 and the contact portion 1533, and be exposed from the first buffer element 1521 and the second movable portion 1220. For example, the engaging element 1540 can pass through the through hole 1532. This prevents the second movable portion 1220 from directly impacting the fixed portion 1100 when the second movable portion 1220 moves relative to the fixed portion 1100, thereby increasing the durability of the optical element driving mechanism 1000.
[0195] In some embodiments, as Figure 2CAs shown, contact portion 1533 may have a contact surface 1534, which may face away from movable assembly 1200 and drive assembly 1400. Engagement element 1540 may directly contact contact surface 1534 to increase the engagement area between first cushioning element 1521 and engagement element 1540, thereby increasing engagement strength. In some embodiments, first setting portion 1225 may have a first setting surface 1226 and a recessed portion 1227 recessed from first setting surface 1226. Recessed portion 1227 may have a second setting surface 1228. In some embodiments, contact portion 1533 may directly contact first setting surface 1226 and be spaced apart from second setting surface 1228. Engagement element 1540 may be disposed in recessed portion 1227, for example, directly contacting second setting surface 1228 to separate contact portion 1533 from second setting surface 1228. In some embodiments, the movable component 1200 (eg, the second movable portion 1220 ), the first buffer element 1521 , and the fixed portion 1100 (eg, the outer frame 1110 ) may be arranged along the third axis 1913 , and the first buffer element 1521 may extend along the second axis 1912 .
[0196] Figure 4A is a top view of some components of the optical element driving mechanism 1000, Figure 4B 、 Figure 4C is a side view of some components of the optical element drive mechanism 1000, Figure 4D FIG. 1 is a schematic diagram of some components of the optical element driving mechanism 1000. Figures 4A to 4D As shown, in addition to the first cushioning element 1521, the optical element driving mechanism 1000 may further include a second cushioning element 1522, a third cushioning element 1523, a fourth cushioning element 1524, a fifth cushioning element 1525, and a sixth cushioning element 1526. The first cushioning element 1521, the second cushioning element 1522, the third cushioning element 1523, the fourth cushioning element 1524, the fifth cushioning element 1525, and the sixth cushioning element 1526 may be collectively referred to as a cushioning assembly 1520, and may be disposed between the movable assembly 1200 and the fixed portion 1100. In some embodiments, the structural details of the second cushioning element 1522, the third cushioning element 1523, the fourth cushioning element 1524, the fifth cushioning element 1525, and the sixth cushioning element 1526 may be the same or similar to those of the first cushioning element 1521 and are not further described herein.
[0197] In some embodiments, the buffer assembly 1520 can be flexible; for example, its Young's modulus can be smaller than that of the outer frame 1110 and the base 1120. Furthermore, when the movable assembly 1200 is in the first position (e.g., when the driving assembly 1400 is not powered), the buffer assembly 1520 (e.g., the first buffer element 1521) only contacts either the movable assembly 1200 or the fixed portion 1100. This protects the movable assembly 1200 from direct contact with the fixed portion 1100 during movement.
[0198] In some embodiments, as Figure 4A As shown, when viewed along first axis 1921, movable assembly 1200 (e.g., second movable portion 1220) may have a polygonal shape and may include a first side 1241, a second side 1242, a third side 1243, and a fourth side 1244. First side 1241 is adjacent to second side 1242 and fourth side 1244, and third side 1243 is also adjacent to second side 1242 and fourth side 1244. In some embodiments, first cushioning element 1521 may be disposed on first side 1241, second cushioning element 1522 and third cushioning element 1523 may be disposed on second side 1242, fourth cushioning element 1524 and fifth cushioning element 1525 may be disposed on third side 1243, and sixth cushioning element 1526 may be disposed on fourth side 1244. This protects the sides of second movable portion 1220 from direct collision with fixed portion 1100 during movement.
[0199] In some embodiments, as Figure 4B 、 Figure 4C As shown, the distance between first cushioning element 1521 and bottom surface 1128 of base 1120 can be different from the distance between first cushioning element 1521 and bottom surface 1128 of base 1120. For example, first cushioning element 1521 can have a first distance 1971 from bottom surface 1128 of base 1120, while other cushioning elements (e.g., second cushioning element 1522) can have a second distance 1972 from bottom surface 1128 of base 1120, with first distance 1971 and second distance 1972 being different. For example, first distance 1971 can be smaller than second distance 1972 to allow first circuit element 1310 to be positioned on first side 1241.
[0200] In some embodiments, as Figure 3A 、 Figure 4AAs shown, the optical element driving mechanism 1000 may further include a guide assembly 1430 disposed between the first movable portion 1210 and the second movable portion 1220 to guide the movement direction of the first movable portion 1210 relative to the second movable portion 1220. For example, the guide assembly 1430 may include a first guide element 1431 and a second guide element 1432, which may have a cylindrical shape and extend along the first axis 1911. In some embodiments, the first guide element 1431 and the second guide element 1432 may be aligned along the second axis 1912. This allows the first movable portion 1210 to move relative to the second movable portion 1220 along the first axis 1911, thereby achieving an autofocus function.
[0201] Figure 5A is a schematic diagram of the first circuit element 1310. Figures 4A to 4D as well as Figure 5A As shown, the first circuit element 1310 may include a first section 1311, a second section 1312, a third section 1313, a fourth section 1314, a fifth section 1315, a sixth section 1316, a seventh section 1317, an eighth section 1318, a ninth section 1319, a tenth section 1320, an eleventh section 1321, a twelfth section 1322, a thirteenth section 1323, a fourteenth section 1324, a fifteenth section 1325, a sixteenth section 1326, a substrate 1327, a first connecting portion 1511, a second connecting portion 1512, and a third connecting portion 1513.
[0202] In some embodiments, the first circuit element 1310 can be fixedly mounted on the second movable portion 1220 via a first connecting portion 1511, and can be fixedly mounted on the first movable portion 1210 via a second connecting portion 1512. The first segment 1311 and the second segment 1312 can connect to the first connecting portion 1511. In some embodiments, the first segment 1311 and the second segment 1312 can extend in the direction of the third axis 1913, while the first connecting portion 1511 can extend in the direction of the second axis 1912. In other words, the first segment 1311 and the second segment 1312 extend in a direction different from the direction in which the first connecting portion 1511 extends.
[0203] In some embodiments, the third section 1313 is connected to the second section 1312, the fourth section 1314 is connected to the third section 1313, the fifth section 1315 is connected to the fourth section 1314, the sixth section 1316 is connected to the fifth section 1315, the seventh section 1317 is connected to the sixth section 1316, the eighth section 1318 is connected to the seventh section 1317, the ninth section 1319 is connected to the eighth section 1318, the tenth section 1320 is connected to the ninth section 1319 and the second connecting portion 1512, and the eleventh section 1321 is connected to the ninth section 1322. 1321 is connected to the second connection part 1512, the twelfth section 1322 is connected to the eleventh section 1321, the third connection part 1513 is connected to the twelfth section 1322, the thirteenth section 1323 is connected to the first section 1311, the fourteenth section 1324 is connected to the thirteenth section 1323, the fifteenth section 1325 is connected to the fourteenth section 1324, the sixteenth section 1326 is connected to the fifteenth section 1325, and the substrate 1327 is connected to the sixteenth section 1326, and can also be fixedly set on the base 1120.
[0204] In some embodiments, the first circuit element 1310 is bendable, thereby allowing the first movable portion 1210 to move relative to the second movable portion 1220, and also allowing the second movable portion 1220 to move relative to the fixed portion 1100. In some embodiments, the second section 1312 and the third section 1313 extend in different directions, the third section 1313 and the fourth section 1314 extend in different directions, the fourth section 1314 and the fifth section 1315 extend in different directions, the fifth section 1315 and the sixth section 1316 extend in different directions, the sixth section 1316 and the seventh section 1317 extend in different directions, the seventh section 1317 and the eighth section 1318 extend in different directions, the eighth section 1318 and the ninth section 1319 extend in different directions, and the ninth section 1319 and the tenth section 1320 extend in different directions. For example, the third section 1313, the fifth section 1315, the seventh section 1317, and the ninth section 1319 can extend along the second axis 1912, and the fourth section 1314, the sixth section 1316, the eighth section 1318, and the tenth section 1320 can extend along the third axis 1913, so that the first circuit element 1310 can be bent, thereby increasing the flexibility of the first circuit element 1310.
[0205] In some embodiments, the eleventh section 1321 has an arc-shaped structure, the twelfth section 1322 extends along the second axis 1912, the thirteenth section 1323 extends along the second axis 1912, the fourteenth section 1324 extends along the third axis 1913, the fifteenth section 1325 extends along the second axis 1912, and the sixteenth section 1326 extends along the first axis 1911. The substrate 1927 is located between the base 1120 and the second circuit element 1330, and the substrate 1927 is fixedly connected to the base 1120 and the second circuit element 1330. In other words, on the first axis 1911, the first circuit element 1310 may be partially disposed between the base 1120 and the second circuit element 1330 (e.g., the substrate 1327), and partially disposed between the movable assembly 1200 and the outer frame 1110 (e.g., the thirteenth section 1323, the fourteenth section 1324, the fifteenth section 1325, and the sixteenth section 1326).
[0206] In some embodiments, an additional damping element 1630 may be provided between the first circuit element 1310 and the second movable portion 1220 to movably connect a portion of the first circuit element 1310 and the second movable portion 1220. Figure 4D As shown, the damping element 1630 can be disposed between the second movable portion 1220 and the thirteenth section 1323, the fourteenth section 1324, the fifteenth section 1325, and the sixteenth section 1326. For example, it can be disposed at the bent portion of the first circuit element 1310 to absorb vibration and thereby prevent damage to the bent portion of the first circuit element 1310. In some embodiments, the material of the damping element 1630 may include a flexible element, such as gel.
[0207] Figure 5B is a cross-sectional view of the first circuit element 1310. Figure 5B As shown, the first circuit element 1310 may include a plurality of conductive traces 1341, a plurality of protective layers 1342, and an insulating layer 1343. The protective layer 1342 may cover the conductive traces 1341, and the plurality of conductive traces 1341 and the plurality of protective layers 1342 may be disposed within the same insulating layer 1343. The conductive traces 1341 may, for example, comprise a conductive metal, while the protective layers 1342 and insulating layers 1343 may comprise insulating materials, and the materials of the protective layers 1342 and insulating layers 1343 may be different. This allows electrical signals to be transmitted within the first circuit element 1310 via the conductive traces 1341.
[0208] In some embodiments, as Figure 4A 、 Figure 5AAs shown, the conductive trace 1341 can be exposed from the first circuit element 1310 at the second connection portion 1512 and the third connection portion 1513, allowing other components to be electrically connected via the conductive trace 1341. For example, an additional aperture element (not shown) can be disposed above the optical element driving mechanism 1000, and this aperture element can be electrically connected to the conductive trace 1341 exposed at the second connection portion 1512, thereby allowing the optical element driving mechanism 1000 to function in conjunction with other components. In addition, the third connection portion 1513 can be connected to the first coil 1411 or the second coil 1412 to provide energy to the first coil 1411 or the second coil 1412.
[0209] Figure 6A 、 Figure 6B 、 Figure 6C is a partial enlarged view of the base 1120 when viewed from different directions, wherein Figure 6C yes Figure 4A The enlarged image of the middle region R2. Figure 4C 、 Figures 6A to 6C As shown, the base 1120 may have a plurality of grooves 1121 located on an outer surface 1127 of the base 1120. In some embodiments, the outer surface 1127 may be parallel to the first axis 1911. In some embodiments, the grooves 1121 may have a first groove portion 1122, a second groove portion 1123, and a connecting portion 1124. The first groove portion 1122 may be connected to the second groove portion 1123 via the connecting portion 1124.
[0210] In some embodiments, first groove portion 1122 may be connected to bottom surface 1128 and may have a trapezoidal shape. For example, the side of first groove portion 1122 connected to bottom surface 1128 has a first width 1931, and the side of first groove portion 1122 connected to connection portion 1124 has a second width 1932, and first width 1931 and second width 1932 are different. For example, first width 1931 may be greater than second width 1932 to facilitate demolding during manufacturing of base 1120.
[0211] In some embodiments, connecting portion 1124 may have a third width 1933, and third width 1933 may be different from first width 1931 and second width 1932. For example, first width 1931 may be greater than third width 1933, while second width 1932 may be less than third width 1933. In some embodiments, circuitry may be embedded in base 1120, and circuit terminals 1125 of this circuitry may be exposed from base 1120, for example, at connecting portion 1124. In some embodiments, multiple circuit terminals 1125 may be exposed from the same connecting portion 1124.
[0212] In some embodiments, the base 1120 may further include a plurality of grooves 1126 recessed from the outer surface 1127 and extending in the direction of the first axis 1911. This increases the surface area of the base 1120, thereby increasing the bonding strength when the outer frame 1110 and the base 1120 are joined using the bonding element 1111. For example, the bonding element 1111 may be disposed between the outer frame 1110 and the base 1120 and may be disposed in the grooves 1126. In some embodiments, the grooves 1121 may be located between the plurality of grooves 1126.
[0213] In some embodiments, as Figure 6C As shown, measured from outer surface 1127, first recess portion 1122 may have a first depth 1981, connecting portion 1124 may have a second depth 1982, second recess portion 1123 may have a third depth 1983, and groove 1126 may have a fourth depth 1984. First depth 1981, second depth 1982, third depth 1983, and fourth depth 1984 may be different from one another. For example, first depth 1981 may be greater than second depth 1982 and fourth depth 1984, and less than third depth 1983. Second depth 1982 may be less than third depth 1983 and greater than fourth depth 1984. Third depth 1983 may be greater than fourth depth 1984.
[0214] Figure 7A 、 Figure 7B 、 Figure 7C FIG. 1 is a schematic diagram of some components of the optical element driving mechanism 1000. Figure 2D 、 Figure 2E 、 7A to 7C As shown, the connection assembly 1500 may include a first connection element 1501, a second connection element 1502, a third connection element 1503, a fourth connection element 1504, a fifth connection element 1505, a sixth connection element 1506, a seventh connection element 1507, a first connection portion 1511, a second connection portion 1512, a third connection portion 1513 and a fourth reinforcement element 1514.
[0215] In some embodiments, the first connecting element 1501, the second connecting element 1502, the third connecting element 1503, and the fourth connecting element 1504 may be disposed on the second movable portion 1220, while the fifth connecting element 1505, the sixth connecting element 1506, and the seventh connecting element 1507 may be disposed on the base 1120. In some embodiments, the first connecting portion 1511, the second connecting portion 1512, and the third connecting portion 1513 may be connected to each other via a fourth reinforcing element 1514 and may be disposed between the base 1120 and the second movable portion 1220. In some embodiments, the first connecting element 1501 and the fifth connecting element 1505 may be disposed on both sides of the first connecting portion 1511, the second connecting element 1502 and the sixth connecting element 1506 may be disposed on both sides of the second connecting portion 1512, and the third connecting element 1503 and the seventh connecting element 1507 may be disposed on both sides of the third connecting portion 1513. The fourth connecting element 1504 may be disposed in the accommodating space 1950 between the base 1120 and the second movable portion 1220 .
[0216] In some embodiments, as Figure 2D 、 Figure 2E As shown, first connecting element 1501, second connecting element 1502, and third connecting element 1503 may be located on first virtual plane 1941, and the normal vector of first virtual plane 1941 may be parallel to principal axis 1900 (first axis 1911). For example, first virtual plane 1941 may pass through first connecting element 1501, second connecting element 1502, and third connecting element 1503. In other words, a portion of first connecting element 1501, second connecting element 1502, and third connecting element 1503 may be located on one side of first virtual plane 1941, and the remaining portion may be located on the other side of first virtual plane 1941.
[0217] In some embodiments, as Figure 2D 、 Figure 2E As shown, the fifth connecting element 1505, the sixth connecting element 1506, and the seventh connecting element 1507 may be located on a second virtual plane 1942, and the normal vector of the second virtual plane 1942 may be parallel to the main axis 1900 (the first axis 1911). For example, the second virtual plane 1942 may pass through the centers of the fifth connecting element 1505, the sixth connecting element 1506, and the seventh connecting element 1507, and the first virtual plane 1941 and the second virtual plane 1942 may be parallel to each other.
[0218] In some embodiments, the fourth connecting element 1504 is not located on the first virtual plane 1941 or the second virtual plane 1942. For example, the fourth connecting element 1504 may be located between the first virtual plane 1941 and the second virtual plane 1942, and neither the first virtual plane 1941 nor the second virtual plane 1942 passes through the fourth connecting element 1504. For example, both may be separated from the fourth connecting element 1504 by a distance greater than zero. In some embodiments, along the first axis 1911, the fourth connecting element 1504 may have a first height 1921, and the accommodating space 1950 may have a second height 1922, with the first height 1921 being less than the second height 1922. In other words, the fourth connecting element 1504 does not normally support the second movable portion 1220 and the base 1120. Instead, it serves as a stopper to prevent damage to the second movable portion 1220 when the second movable portion 1220 tilts.
[0219] In some embodiments, the first connecting element 1501, the second connecting element 1502, the third connecting element 1503, the fourth connecting element 1504, the fifth connecting element 1505, the sixth connecting element 1506, and the seventh connecting element 1507 may have a spherical shape and may be made of, for example, ceramic. This allows the second movable portion 1220 to roll when moving relative to the base 1120, reducing friction between the second movable portion 1220 and the base 1120 and facilitating movement of the second movable portion 1220. It should be noted that since three points can define a plane, the first connecting element 1501, the second connecting element 1502, and the third connecting element 1503 define a first virtual plane 1941, and the fifth connecting element 1505, the sixth connecting element 1506, and the seventh connecting element 1507 define a second virtual plane 1942. This prevents the main shaft 1900 of the optical element driving mechanism 1000 from tilting during operation, thereby improving its optical performance.
[0220] In some embodiments, as Figure 2A 、 Figure 7A 、 Figure 7B As shown, the optical element driving mechanism 1000 may include sensing elements 1601, 1602, 1603, and a sensing magnetic element 1610. Sensing elements 1601 and 1602 may be disposed on the base 1120, while sensing element 1603 may be disposed on the second movable portion 1220, and sensing magnetic element 1610 may be disposed on the first movable portion 1210. In some embodiments, sensing elements 1601 and 1602 may correspond to the first magnetic element 1421 and the second magnetic element 1422, respectively, and may partially overlap on the first axis 1911, for example. Sensing element 1603 may correspond to sensing magnetic element 1610, and may at least partially overlap on the third axis 1913, for example.
[0221] In some embodiments, the magnetic sensing element 1610 may include a magnet, and the sensing elements 1601, 1602, and 1603 may include a Hall effect sensor, a magnetoresistance effect sensor (MR sensor), a giant magnetoresistance effect sensor (GMRSensor), a tunneling magnetoresistance effect sensor, or a magnetic field sensing element.
[0222] A Tunneling Magnetoresistance Effect Sensor (TMR Sensor) or a Fluxgate Sensor can be used to sense the positions of the first movable portion 1210 and the second movable portion 1220 during movement, thereby precisely controlling the first movable portion 1210 and the second movable portion 1220 .
[0223] Figure 8A 、 Figure 8B 、 Figure 8C 、 Figure 8D 1 is a schematic diagram of some components of the optical element driving mechanism 1000 when viewed from different directions, wherein the second movable portion 1220 is further omitted. Figure 8B As shown, the fourth reinforcing element 1514 may be at least partially exposed from the first connecting portion 1511, the second connecting portion 1512, and the third connecting portion 1513, and its material may include a non-magnetic metal. Thus, the first connecting portion 1511, the second connecting portion 1512, and the third connecting portion 1513 may be connected to each other through the fourth reinforcing element 1514. In some embodiments, as Figure 2D 、 Figure 2E 、 Figure 8B As shown, the fourth reinforcing element 1514 may at least partially overlap with the first connecting element 1501 , the second connecting element 1502 , the third connecting element 1503 , the fifth connecting element 1505 , the sixth connecting element 1506 , the seventh connecting element 1507 , and the second movable portion 1220 , and may not overlap with the fourth connecting element 1504 .
[0224] Furthermore, the fourth reinforcing element 1514 may include a first end 1561 and a second end 1562, wherein the first end 1561 may be disposed on the first connecting portion 1511 and at least partially exposed therefrom, and the second end 1562 may be disposed on the third connecting portion 1513 and at least partially exposed therefrom. In some embodiments, the first end 1561 and the second end 1562 may extend in the same direction, for example, in a direction parallel to the second axis 1912.
[0225] In some embodiments, as Figure 2D 、 Figure 2E 、 Figure 8B As shown, the first connection portion 1511 may include a first recess 1515 and a fifth recess 1541, the second connection portion 1512 may include a second recess 1516 and a sixth recess 1542, the third connection portion 1513 may include a third recess 1517 and a seventh recess 1543, and the base 1120 may include a fourth recess 1518. The first connection element 1501 may be disposed in the first recess 1515, the second connection element 1502 may be disposed in the second recess 1516, the third connection element 1503 may be disposed in the third recess 1517, the fourth connection element 1504 may be disposed in the fourth recess 1518, the fifth connection element 1505 may be disposed in the fifth recess 1541, the sixth connection element 1506 may be disposed in the sixth recess 1542, and the seventh connection element 1507 may be disposed in the seventh recess 1543.
[0226] In some embodiments, along the direction in which first axis 1911 extends, first recess 1515 and fifth recess 1541 may at least partially overlap, second recess 1516 and sixth recess 1542 may at least partially overlap, and third recess 1517 and seventh recess 1543 may at least partially overlap. In other words, along the direction in which first axis 1911 extends, first connecting element 1501 and fifth connecting element 1505 may at least partially overlap, second connecting element 1502 and sixth connecting element 1506 may at least partially overlap, and third connecting element 1503 and seventh connecting element 1507 may at least partially overlap, thereby reducing dimensions in other directions and achieving miniaturization.
[0227] In some embodiments, the first recess 1515 includes a first recessed surface 1551, the second recessed surface 1516 includes a second recessed surface 1552, the third recessed surface 1517 includes a third recessed surface 1553, the fourth recessed surface 1518 includes a fourth recessed surface 1554, the fifth recessed surface 1541 includes a fifth recessed surface 1555, the sixth recessed surface 1542 includes a sixth recessed surface 1556, and the seventh recessed surface 1543 includes a seventh recessed surface 1557, and the first recessed surface 1551, the second recessed surface 1552, the third recessed surface 1553, and the fourth recessed surface 1554 may face the same direction, while the first recessed surface 1551, the second recessed surface 1552, the third recessed surface 1553, and the fourth recessed surface 1554 and the fifth recessed surface 1555, the sixth recessed surface 1556, and the seventh recessed surface 1557 may face opposite directions. For example, the first concave surface 1551, the second concave surface 1552, the third concave surface 1553, and the fourth concave surface 1554 may face away from the base 1120, while the fifth concave surface 1555, the sixth concave surface 1556, and the seventh concave surface 1557 may face toward the base 1120, and their normal vectors may be parallel to the first axis 1911.
[0228] In some embodiments, as Figure 8B As shown, when viewed along the first axis 1911, the second recessed portion 1516 and the third recessed portion 1517 are arranged in a direction parallel to the third axis 1913, while the first recessed portion 1515 and the second recessed portion 1516 are arranged in a direction parallel to the second axis 1912. In some embodiments, as Figure 8B As shown, in the direction in which the second axis 1912 extends, the first concave surface 1551 has a first dimension 1961, the second concave surface 1552 has a second dimension 1962, the third concave surface 1553 has a third dimension 1963, and the fourth concave surface 1554 has a fourth dimension 1964. The first dimension 1961 can be the same as the second dimension 1962, the first dimension 1961 can be different from the third dimension 1963 and the fourth dimension 1964, and the third dimension 1963 can be different from the fourth dimension 1964. For example, the first dimension 1961 can be smaller than the third dimension 1963, and the third dimension 1963 can be smaller than the fourth dimension 1964. This prevents the optical element driving mechanism 1000 from being unable to be assembled due to tolerances.
[0229] In some embodiments, a lubricating element 1620 (for example, lubricating oil) may be provided on the first recess 1515, the second recess 1516, the third recess 1517, the fourth recess 1518, the fifth recess 1541, the sixth recess 1542, and the seventh recess 1543 to further reduce the friction between the connecting component 1500, the second movable part 1220, and the base 1120.
[0230] In some embodiments, additional reinforcing elements may be added to the second movable portion 1220 to enhance its mechanical strength and simultaneously provide a magnetic conductive function. Figure 7C 、 Figures 8A to 8D As shown, the second movable portion 1220 may include a main body 1224, which may include a first reinforcement element 1221, a second reinforcement element 1222, and a third reinforcement element 1223. In some embodiments, the first reinforcement element 1221, the second reinforcement element 1222, and the third reinforcement element 1223 may be separated from each other and may be made of a magnetically permeable metal material. It should be noted that in some embodiments, the first reinforcement element 1221, the second reinforcement element 1222, and the third reinforcement element 1223 may be at least partially exposed from the main body 1224.
[0231] In some embodiments, as Figure 8A 、 Figure 8B As shown, the first reinforcing element 1221 may include a first surface 1231, the second reinforcing element 1222 may include a second surface 1232, and the third reinforcing element 1223 may include a third surface 1233. The first surface 1231, the second surface 1232, and the third surface 1233 may face away from the drive assembly 1400. For example, the first surface 1231 may face away from the first magnetic element 1421, the second surface 1232 may face away from the second magnetic element 1422, and the third surface 1233 may face away from the third magnetic element 1423. The first surface 1231, the second surface 1232, and the third surface 1233 may face in different directions. For example, the normal vectors of the first surface 1231 and the third surface 1233 may be parallel to the second axis 1912 and face in opposite directions. The normal vector of the second surface 1322 may be parallel to the first axis 1911. In this way, the mechanical strength of the second movable portion 1220 can be enhanced, and the direction of the magnetic lines of force of the magnetic assembly 1420 can be concentrated, thereby improving the performance of the optical element driving mechanism 1000 .
[0232] In summary, the disclosed embodiments provide an optical element drive mechanism comprising a movable portion, a fixed portion, and a drive assembly.
