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 thinner designs to provide users with more choices.

[0003] The aforementioned electronic devices with camera or video recording functions are usually provided with an optical element driving mechanism to drive the optical element (e.g., lens) to move along the optical axis, thereby achieving the functions of auto focus (AF) or optical image stablization (OIS). Light can pass through the aforementioned optical element to form an image on the photosensitive element. However, the current trend of mobile devices is to have a smaller size and higher durability, so how to effectively reduce the size of the optical element driving mechanism and improve its durability has become an important issue.

In some embodiments, the first cushioning element 1521 can be fixedly set on the first setting portion 1225 by the coupling element 1540, such as 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. Thus, when the second movable portion 1220 moves relative to the fixed portion 1100, the second movable portion 1220 can be prevented from directly hitting the fixed portion 1100, thereby increasing the durability of the optical element driving mechanism 1000.

[0191] In some embodiments, Figure 2C As shown, the contact portion 1533 may have a contact surface 1534, which may face away from the movable component 1200 and the driving component 1400, and the engaging element 1540 may directly contact the contact surface 1534 to increase the engaging area between the first buffer component 1521 and the engaging element 1540, thereby increasing the engaging strength. In some embodiments, the first setting portion 1225 may have a first setting surface 1226 and a recessed portion 1227 recessed from the first setting surface 1226, and the recessed portion 1227 may have a second setting surface 1228. In some embodiments, the contact portion 1533 may directly contact the first setting surface 1226 and be separated from the second setting surface 1228, and the engaging element 1540 may be disposed in the recessed portion 1227, for example, may directly contact the second setting surface 1228 to separate the contact portion 1533 from the 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 .

[0192] 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 driving mechanism 1000, Figure 4D Schematic diagram of some components of the optical element driving mechanism 1000. FIG. 4A to FIG. 4DAs shown, in addition to the first buffer element 1521, the optical element driving mechanism 1000 may further include a second buffer element 1522, a third buffer element 1523, a fourth buffer element 1524, a fifth buffer element 1525, and a sixth buffer element 1526, and the first buffer element 1521, the second buffer element 1522, the third buffer element 1523, the fourth buffer element 1524, the fifth buffer element 1525, and the sixth buffer element 1526 may be collectively referred to as a buffer 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 buffer element 1522, the third buffer element 1523, the fourth buffer element 1524, the fifth buffer element 1525, and the sixth buffer element 1526 may be the same or similar to those of the first buffer element 1521, and will not be repeated herein.

[0193] In some embodiments, the buffer component 1520 may be flexible, for example, its Young's modulus may be smaller than the Young's modulus of the outer frame 1110 and the Young's modulus of the base 1120. In addition, when the movable component 1200 is located at the first position (for example, the position when the driving component 1400 is not powered on), the buffer component 1520 (for example, the first buffer element 1521) only contacts one of the movable component 1200 or the fixed part 1100. In this way, the movable component 1200 can be protected from directly contacting the fixed part 1100 when moving.

[0194] In some embodiments, Figure 4A As shown, when viewed along the first axis 1921, the movable assembly 1200 (e.g., the second movable portion 1220) may have a polygonal shape, and may have a first side 1241, a second side 1242, a third side 1243, and a fourth side 1244, wherein the first side 1241 is adjacent to the second side 1242 and the fourth side 1244, and the third side 1243 is also adjacent to the second side 1242 and the fourth side 1244. In some embodiments, the first buffer element 1521 may be disposed on the first side 1241, the second buffer element 1522 and the third buffer element 1523 may be disposed on the second side 1242, the fourth buffer element 1524 and the fifth buffer element 1525 may be disposed on the third side 1243, and the sixth buffer element 1526 may be disposed on the fourth side 1244. Thus, the sides of the second movable portion 1220 may be protected to prevent the second movable portion 1220 from directly colliding with the fixed portion 1100 when the second movable portion 1220 moves.

[0195] In some embodiments, Figure 4B , Figure 4CAs shown, the distance between the first buffer element 1521 and the bottom surface 1128 of the base 1120 may be different from that of other buffer elements. For example, the first buffer element 1521 may have a first distance 1971 with the bottom surface 1128 of the base 1120, while other buffer elements (such as the second buffer element 1522) may have a second distance 1972 with the bottom surface 1128 of the base 1120, and the first distance 1971 is different from the second distance 1972. For example, the first distance 1971 may be smaller than the second distance 1972 to allow the first circuit element 1310 to be disposed on the first side 1241.

[0196] In some embodiments, Figure 3A , Figure 4A As shown, the optical element driving mechanism 1000 may further include a guide assembly 1430, which is disposed between the first movable portion 1210 and the second movable portion 1220, and is used 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 columnar shape and may extend on the first axis 1911. In some embodiments, the first guide element 1431 and the second guide element 1432 may be arranged on the second axis 1912. Thus, the first movable portion 1210 may be allowed to move relative to the second movable portion 1220 on the first axis 1911 to achieve an autofocus function.

[0197] Figure 5A is a schematic diagram of the first circuit element 1310. FIG. 4A to FIG. 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.

The first segment 1311 and the second segment 1312 may connect the first connection portion 1511. In some embodiments, the first segment 1311 and the second segment 1312 may extend in the direction of the third axis 1913, and the first connection portion 1511 may extend in the direction of the second axis 1912. That is, the direction in which the first segment 1311 and the second segment 1312 extend is different from the direction in which the first connection portion 1511 extends.

[0199] 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 connection portion 1512, and the eleventh section 1321 is connected to the ninth section 1319 and the second connection portion 1512. 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, the substrate 1327 is connected to the sixteenth section 1326, and can also be fixedly set on the base 1120.

[0200] In some embodiments, the first circuit element 1310 can be bent, so that the first movable portion 1210 can be allowed to move relative to the second movable portion 1220, and the second movable portion 1220 can be allowed to move relative to the fixed portion 1100. In some embodiments, the second segment 1312 and the third segment 1313 extend in different directions, the third segment 1313 and the fourth segment 1314 extend in different directions, the fourth segment 1314 and the fifth segment 1315 extend in different directions, the fifth segment 1315 and the sixth segment 1316 extend in different directions, the sixth segment 1316 and the seventh segment 1317 extend in different directions, the seventh segment 1317 and the eighth segment 1318 extend in different directions, the eighth segment 1318 and the ninth segment 1319 extend in different directions, and the ninth segment 1319 and the tenth segment 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.

[0201] In some embodiments, the eleventh section 1321 has an arc-shaped structure, the twelfth section 1322 extends on the second axis 1912, the thirteenth section 1323 extends on the second axis 1912, the fourteenth section 1324 extends on the third axis 1913, the fifteenth section 1325 extends on the second axis 1912, the sixteenth section 1326 extends on the first axis 1911, and 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. That is, on the first axis 1911, the first circuit element 1310 may be partially disposed between the base 1120 and the second circuit element 1330 (for example, the substrate 1327), and partially disposed between the movable component 1200 and the outer frame 1110 (for example, the thirteenth section 1323, the fourteenth section 1324, the fifteenth section 1325, and the sixteenth section 1326).

[0202] In some embodiments, an additional damping element 1630 may be disposed 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 4DAs shown, the damping element 1630 may 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 may be disposed at the portion where the first circuit element 1310 is bent to absorb vibration, thereby preventing the bending portion of the first circuit element 1310 from being damaged. In some embodiments, the material of the damping element 1630 may include a flexible element, such as gel.

[0203] 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 lines 1341, a plurality of protective layers 1342, and an insulating layer 1343. The protective layer 1342 may cover the conductive lines 1341, and the plurality of conductive lines 1341 and the plurality of protective layers 1342 may be disposed in the same insulating layer 1343. The conductive lines 1341 may include, for example, a conductive metal, and the protective layer 1342 and the insulating layer 1343 may include insulating materials, and the materials of the protective layer 1342 and the insulating layer 1343 may be different from each other. Thus, an electrical signal may be allowed to be transmitted in the first circuit element 1310 through the conductive lines 1341.

[0204] In some embodiments, Figure 4A , Figure 5A As shown, the conductive circuit 1341 can be exposed to the first circuit element 1310 at the second connection portion 1512 and the third connection portion 1513 to allow other elements to be electrically connected through the conductive circuit 1341. For example, an additional aperture element (not shown) can be arranged above the optical element driving mechanism 1000, and this aperture element can be electrically connected to the conductive circuit 1341 exposed by the second connection portion 1512, so as to allow the optical element driving mechanism 1000 to work together with other elements. 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.

[0205] Fig. 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 view of the middle area R2. Figure 4C , FIG. 6A to FIG. 6CAs 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 groove 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.

[0206] In some embodiments, the first groove portion 1122 may be connected to the bottom surface 1128 and may have a trapezoidal shape. For example, the first groove portion 1122 has a first width 1931 on one side connected to the bottom surface 1128, and has a second width 1932 on one side connected to the connection portion 1124, and the first width 1931 and the second width 1932 are different from each other. For example, the first width 1931 may be greater than the second width 1932 so that the base 1120 can be demolded more easily when manufacturing.

[0207] In some embodiments, the connection portion 1124 may have a third width 1933, and the third width 1933 may be different from the first width 1931 and the second width 1932. For example, the first width 1931 may be greater than the third width 1933, and the second width 1932 may be less than the third width 1933. In some embodiments, a circuit may be embedded in the base 1120, and the circuit terminal 1125 of the circuit may be exposed from the base 1120, for example, may be exposed from the base 1120 at the connection portion 1124. In some embodiments, a plurality of circuit terminals 1125 may be exposed from the same connection portion 1124.

[0208] In some embodiments, the base 1120 may further have a plurality of grooves 1126 that are recessed from the outer surface 1127 and extend in the direction of the first axis 1911. Thus, the surface area of ​​the base 1120 may be increased, thereby increasing the adhesive strength when the outer frame 1110 and the base 1120 are joined using the adhesive element 1111. For example, the adhesive 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.

[0209] In some embodiments, Figure 6CAs shown, the first groove portion 1122 may have a first depth 1981, the connecting portion 1124 may have a second depth 1982, the second groove portion 1123 may have a third depth 1983, and the groove 1126 may have a fourth depth 1984, and the first depth 1981, the second depth 1982, the third depth 1983, and the fourth depth 1984 are different from each other. For example, the first depth 1981 may be greater than the second depth 1982 and the fourth depth 1984, and less than the third depth 1983. The second depth 1982 may be less than the third depth 1983, and greater than the fourth depth 1984. The third depth 1983 may be greater than the fourth depth 1984.

[0210] Fig. 7A , Figure 7B , Figure 7C Schematic diagram of some components of the optical element driving mechanism 1000. Figure 2D , Figure 2E , FIG. 7A to FIG. 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.

[0211] In some embodiments, the first connection element 1501, the second connection element 1502, the third connection element 1503, and the fourth connection element 1504 may be disposed on the second movable portion 1220, and the fifth connection element 1505, the sixth connection element 1506, and the seventh connection element 1507 may be disposed on the base 1120. In some embodiments, the first connection portion 1511, the second connection portion 1512, and the third connection portion 1513 may be connected to each other through the fourth reinforcing element 1514, and may be disposed between the base 1120 and the second movable portion 1220. In some embodiments, the first connection element 1501 and the fifth connection element 1505 may be disposed on both sides of the first connection portion 1511, the second connection element 1502 and the sixth connection element 1506 may be disposed on both sides of the second connection portion 1512, and the third connection element 1503 and the seventh connection element 1507 may be disposed on both sides of the third connection portion 1513. The fourth connecting element 1504 may be disposed in the accommodation space 1950 between the base 1120 and the second movable portion 1220 .

[0212] In some embodiments, Figure 2D , Figure 2EAs shown, the first connecting element 1501, the second connecting element 1502, and the third connecting element 1503 may be located on the first virtual plane 1941, and the normal vector of the first virtual plane 1941 may be parallel to the main axis 1900 (the first axis 1911). For example, the first virtual plane 1941 may pass through the first connecting element 1501, the second connecting element 1502, and the third connecting element 1503, that is, a portion of the first connecting element 1501, the second connecting element 1502, and the third connecting element 1503 is located on one side of the first virtual plane 1941, and the rest is located on the other side of the first virtual plane 1941.

[0213] In some embodiments, 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 the 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.

[0214] In some embodiments, the fourth connection element 1504 is not located on the first virtual plane 1941 or the second virtual plane 1942. For example, the fourth connection element 1504 may be located between the first virtual plane 1941 and the second virtual plane 1942, and the first virtual plane 1941 and the second virtual plane 1942 do not pass through the fourth connection element 1504. For example, both may be separated from the fourth connection element 1504 by a distance greater than zero. In some embodiments, on the first axis 1911, the fourth connection element 1504 may have a first height 1921, the accommodating space 1950 may have a second height 1922, and the first height 1921 is smaller than the second height 1922. In other words, the fourth connection element 1504 is not used to support the second movable portion 1220 and the base 1120 at ordinary times, but when the second movable portion 1220 is skewed, it can be used as a stopper to prevent the second movable portion 1220 from being damaged.

[0215] 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 their materials may include ceramics, for example. Thus, the second movable part 1220 can roll when it moves relative to the base 1120 to reduce the friction between the second movable part 1220 and the base 1120, so that the second movable part 1220 can move more easily. 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, which can prevent the main shaft 1900 of the optical element driving mechanism 1000 from being skewed during operation, thereby increasing its optical performance.

[0216] In some embodiments, Figure 2A , Fig. 7A , Figure 7B As shown, the optical element driving mechanism 1000 may include sensing elements 1601, 1602, 1603, and a sensing magnetic element 1610. The sensing elements 1601 and 1602 may be disposed on the base 1120, the sensing element 1603 may be disposed on the second movable portion 1220, and the sensing magnetic element 1610 may be disposed on the first movable portion 1210. In some embodiments, the sensing element 1601 and the sensing element 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. The sensing element 1603 may correspond to the sensing magnetic element 1610, and may at least partially overlap on the third axis 1913, for example.

[0217] In some embodiments, the sensing magnetic element 1610 may include a magnet, and the sensing elements 1601, 1602, and 1603 may include a Hall effect sensor, a magnetoresistance effect sensor (Magnetoresistance Effect Sensor, MR Sensor), a giant magnetoresistance effect sensor (Giant Magnetoresistance Effect Sensor, GMRSensor), a tunneling magnetoresistance effect sensor, or a magnetic field sensor.

[0218] The Tunneling Magnetoresistance Effect Sensor (TMR Sensor) or the Fluxgate Sensor can be used to sense the positions of the first movable part 1210 and the second movable part 1220 during movement, so as to accurately control the first movable part 1210 and the second movable part 1220.

[0219] Fig. 8A , Figure 8B , Figure 8C , Fig.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 connection portion 1511, the second connection portion 1512, and the third connection portion 1513, and its material may include a non-magnetic metal. Thus, the first connection portion 1511, the second connection portion 1512, and the third connection 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 .

[0220] In addition, the fourth reinforcing element 1514 may include a first end 1561 and a second end 1562, wherein the first end 1561 may be disposed at the first connection portion 1511 and at least partially exposed from the first connection portion 1511, and the second end 1562 may be disposed at the third connection portion 1513 and at least partially exposed from the third connection portion 1513. 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.

[0221] In some embodiments, Figure 2D , Figure 2E , Figure 8BAs shown, the first connection part 1511 may include a first recessed part 1515 and a fifth recessed part 1541, the second connection part 1512 may include a second recessed part 1516 and a sixth recessed part 1542, the third connection part 1513 may include a third recessed part 1517 and a seventh recessed part 1543, and the base 1120 may include a fourth recessed part 1518.

[0222] In some embodiments, in the direction in which the first axis 1911 extends, the first recessed portion 1515 and the fifth recessed portion 1541 may at least partially overlap, the second recessed portion 1516 and the sixth recessed portion 1542 may at least partially overlap, and the third recessed portion 1517 and the seventh recessed portion 1543 may at least partially overlap. That is, in the direction in which the first axis 1911 extends, the first connecting element 1501 and the fifth connecting element 1505 may at least partially overlap, the second connecting element 1502 and the sixth connecting element 1506 may at least partially overlap, and the third connecting element 1503 and the seventh connecting element 1507 may at least partially overlap, so as to reduce the size in other directions and achieve miniaturization.

[0223] In some embodiments, the first recess 1515 includes a first recess surface 1551, the second recess 1516 includes a second recess surface 1552, the third recess 1517 includes a third recess surface 1553, the fourth recess 1518 includes a fourth recess surface 1554, the fifth recess 1541 includes a fifth recess surface 1555, the sixth recess 1542 includes a sixth recess surface 1556, and the seventh recess 1543 includes a seventh recess surface 1557, and the first recess surface 1551, the second recess surface 1552, the third recess surface 1553, and the fourth recess surface 1554 may face the same direction, while the first recess surface 1551, the second recess surface 1552, the third recess surface 1553, and the fourth recess surface 1554 and the fifth recess surface 1555, the sixth recess surface 1556, and the seventh recess surface 1557 may face opposite directions. For example, the first recessed surface 1551, the second recessed surface 1552, the third recessed surface 1553, and the fourth recessed surface 1554 may face away from the base 1120, while the fifth recessed surface 1555, the sixth recessed surface 1556, and the seventh recessed surface 1557 may face toward the base 1120, and their normal vectors may be parallel to the first axis 1911.

[0224] In some embodiments, 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, and 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 size 1961, the second concave surface 1552 has a second size 1962, the third concave surface 1553 has a third size 1963, and the fourth concave surface 1554 has a fourth size 1964, and the first size 1961 may be the same as the second size 1962, the first size 1961 and the third size 1963 and the fourth size 1964 may be different from each other, and the third size 1963 is different from the fourth size 1964. For example, the first size 1961 may be smaller than the third size 1963, and the third size 1963 may be smaller than the fourth size 1964. In this way, it is possible to avoid the optical element driving mechanism 1000 being unable to be assembled due to tolerance.

[0225] 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.

[0226] In some embodiments, an additional reinforcing element may be added to the second movable portion 1220 to enhance its mechanical strength and also provide a magnetic conductivity function. Figure 7C , FIG. 8A to FIG. 8D As shown, the second movable portion 1220 may include a main body 1224, and the main body 1224 may include a first reinforcing element 1221, a second reinforcing element 1222, and a third reinforcing element 1223. In some embodiments, the first reinforcing element 1221, the second reinforcing element 1222, and the third reinforcing element 1223 may be separated from each other and may have a magnetically conductive metal material. It should be noted that in some embodiments, the first reinforcing element 1221, the second reinforcing element 1222, and the third reinforcing element 1223 may be at least partially exposed from the main body 1224.

[0227] In some embodiments, Fig. 8A , Figure 8BAs 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, and the first surface 1231, the second surface 1232, and the third surface 1233 may face away from the driving 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, and 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 to each other. The normal vector of the second surface 1322 may be parallel to the first axis 1911. Thus, the mechanical strength of the second movable portion 1220 can be enhanced, and the direction of the magnetic lines of force of the magnetic component 1420 can be concentrated to improve the performance of the optical element driving mechanism 1000 .

[0228] In summary, the embodiments of the present disclosure provide an optical element driving mechanism, including a movable part, a fixed part, and a driving assembly. The movable part is used to connect the optical element, the movable part can move relative to the fixed part, and the driving assembly is used to drive the movable part to move relative to the fixed part. As a result, the direction of the movable part moving relative to the fixed part can be made more stable, so as to obtain a better camera effect.

[0229] The special relative positions and size relationships of the components disclosed in the present invention not only enable the driving mechanism to be thinner in a specific direction and smaller overall, but also further enhance the optical quality (such as shooting quality or depth sensing accuracy) of the system by matching different optical modules, and further utilize each optical module to achieve a multiple anti-shake system to greatly enhance the anti-shake effect.
