Description

Technical Field

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

[0002] With the development of technology, many current electronic devices (such as smart phones or digital cameras) have functions of taking pictures or videos. The use of these electronic devices is becoming more and more common, and they are developing towards the direction of convenient and thin-and-light designs to provide users with more choices.

[0003] The aforementioned electronic devices with functions of taking pictures or videos usually are provided with an optical element driving mechanism to drive an optical element (such as a lens) to move along an optical axis, so as to achieve functions of auto focus (AF) or optical image stabilization (OIS).

[0179] Furthermore, ordinal numbers such as "first", "second", etc. used in the specification and claims to modify the elements of the claims do not themselves imply or represent that the claimed element has any previous ordinal number, nor 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 to clearly distinguish one claimed element with a certain name from another claimed element with the same name.

As Figure 2C , Figure 3B shown, the engaging element 1540 can directly contact the concave structure 1531 and the contact portion 1533, and is exposed between 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, it can prevent the second movable portion 1220 from directly hitting the fixed portion 1100, thereby increasing the durability of the optical element driving mechanism 1000.

[0191] In some embodiments, as Figure 2C shown, the contact portion 1533 can have a contact surface 1534, which can face away from the movable component 1200 and the driving component 1400, and the engaging element 1540 can directly contact the contact surface 1534 to increase the bonding area between the first buffer element 1521 and the engaging element 1540, thereby increasing the bonding strength. In some embodiments, the first setting portion 1225 can have a first setting surface 1226 and a concave portion 1227 recessed from the first setting surface 1226, and the concave portion 1227 can have a second setting surface 1228. In some embodiments, the contact portion 1533 can directly contact the first setting surface 1226 and be spaced apart from the second setting surface 1228, and the engaging element 1540 can be arranged in the concave portion 1227, for example, can directly contact the second setting surface 1228 to space the contact portion 1533 from the second setting surface 1228. In some embodiments, the movable component 1200 (such as the second movable portion 1220), the first buffer element 1521, and the fixed portion 1100 (such as the outer frame 1110) can be arranged along the third axis 1913, and the first buffer element 1521 can extend in the second axis 1912.

[0192] Figure 4A is a top view of some elements of the optical element driving mechanism 1000, Figure 4B , Figure 4C is a side view of some elements of the optical element driving mechanism 1000, Figure 4D is a schematic diagram of some elements of the optical element driving mechanism 1000. As Figures 4A to 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. 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 the 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 as or similar to those of the first buffer element 1521, and will not be described in detail herein.

[0193] In some embodiments, the buffer assembly 1520 may be flexible. For example, its Young's modulus may be less than the Young's modulus of the outer frame 1110 and the Young's modulus of the base 1120. In addition, when the movable assembly 1200 is in the first position (e.g., the position when the driving assembly 1400 is not yet powered on), the buffer assembly 1520 (e.g., the first buffer element 1521) contacts only one of the movable assembly 1200 or the fixed portion 1100. Thus, the movable assembly 1200 can be protected from directly contacting the fixed portion 1100 during movement.

[0194] In some embodiments, as Figure 4A 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. 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, each side of the second movable portion 1220 can be protected to avoid direct collision with the fixed portion 1100 when the second movable portion 1220 moves.

[0195] In some embodiments, as 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, there may be a first distance 1971 between the first buffer element 1521 and the bottom surface 1128 of the base 1120, while there may be a second distance 1972 between other buffer elements (such as the second buffer element 1522) and 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 less than the second distance 1972 to allow the first circuit element 1310 to be disposed on the first side 1241.

[0196] In some embodiments, as Figure 3A 、 Figure 4A shown, the optical element driving mechanism 1000 may further include a guiding assembly 1430 disposed between the first movable portion 1210 and the second movable portion 1220 for guiding the movement direction of the first movable portion 1210 relative to the second movable portion 1220. For example, the guiding assembly 1430 may include a first guiding element 1431 and a second guiding element 1432, which may have a columnar shape and may extend on the first axis 1911. In some embodiments, the first guiding element 1431 and the second guiding 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 the function of autofocus.

[0197] Figure 5A is a schematic diagram of the first circuit element 1310. As Figures 4A to 4D and Figure 5A shown, the first circuit element 1310 may include a first segment portion 1311, a second segment portion 1312, a third segment portion 1313, a fourth segment portion 1314, a fifth segment portion 1315, a sixth segment portion 1316, a seventh segment portion 1317, an eighth segment portion 1318, a ninth segment portion 1319, a tenth segment portion 1320, an eleventh segment portion 1321, a twelfth segment portion 1322, a thirteenth segment portion 1323, a fourteenth segment portion 1324, a fifteenth segment portion 1325, a sixteenth segment portion 1326, a substrate 1327, a first connection portion 1511, a second connection portion 1512, and a third connection portion 1513.

[0198] In some embodiments, the first circuit element 1310 may be fixedly disposed on the second movable portion 1220 through the first connecting portion 1511 and may be fixedly disposed on the first movable portion 1210 through the second connecting portion 1512. The first segment portion 1311 and the second segment portion 1312 may connect the first connecting portion 1511. In some embodiments, the first segment portion 1311 and the second segment portion 1312 may extend in the direction of the third axis 1913, while the first connecting portion 1511 may extend in the direction of the second axis 1912. That is, the extending directions of the first segment portion 1311 and the second segment portion 1312 are different from the extending direction of the first connecting portion 1511.

[0199] In some embodiments, the third segment portion 1313 connects the second segment portion 1312, the fourth segment portion 1314 connects the third segment portion 1313, the fifth segment portion 1315 connects the fourth segment portion 1314, the sixth segment portion 1316 connects the fifth segment portion 1315, the seventh segment portion 1317 connects the sixth segment portion 1316, the eighth segment portion 1318 connects the seventh segment portion 1317, the ninth segment portion 1319 connects the eighth segment portion 1318, the tenth segment portion 1320 connects the ninth segment portion 1319 and the second connecting portion 1512, the eleventh segment portion 1321 connects the second connecting portion 1512, the twelfth segment portion 1322 connects the eleventh segment portion 1321, the third connecting portion 1513 connects the twelfth segment portion 1322, the thirteenth segment portion 1323 connects the first segment portion 1311, the fourteenth segment portion 1324 connects the thirteenth segment portion 1323, the fifteenth segment portion 1325 connects the fourteenth segment portion 1324, the sixteenth segment portion 1326 connects the fifteenth segment portion 1325, the substrate 1327 connects the sixteenth segment portion 1326, and may also be fixedly disposed on the base 1120.

[0200] In some embodiments, the first circuit element 1310 can be bent, thus 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 extending directions of the second segment portion 1312 and the third segment portion 1313 are different, the extending directions of the third segment portion 1313 and the fourth segment portion 1314 are different, the extending directions of the fourth segment portion 1314 and the fifth segment portion 1315 are different, the extending directions of the fifth segment portion 1315 and the sixth segment portion 1316 are different, the extending directions of the sixth segment portion 1316 and the seventh segment portion 1317 are different, the extending directions of the seventh segment portion 1317 and the eighth segment portion 1318 are different, the extending directions of the eighth segment portion 1318 and the ninth segment portion 1319 are different, and the extending directions of the ninth segment portion 1319 and the tenth segment portion 1320 are different. For example, the third segment portion 1313, the fifth segment portion 1315, the seventh segment portion 1317, and the ninth segment portion 1319 can extend along the second axis 1912, while the fourth segment portion 1314, the sixth segment portion 1316, the eighth segment portion 1318, and the tenth segment portion 1320 can extend along the third axis 1913, so as to bend the first circuit element 1310, thereby increasing the flexibility of the first circuit element 1310.

[0201] In some embodiments, the eleventh segment portion 1321 has an arc-shaped structure, the twelfth segment portion 1322 extends along the second axis 1912, the thirteenth segment portion 1323 extends along the second axis 1912, the fourteenth segment portion 1324 extends along the third axis 1913, the fifteenth segment portion 1325 extends along the second axis 1912, the sixteenth segment portion 1326 extends along the first axis 1911, and the substrate 1927 is located between the base 1120 and the second circuit element 1330. The substrate 1927 is fixedly connected to the base 1120 and the second circuit element 1330. That is to say, on the first axis 1911, a part of the first circuit element 1310 can be disposed between the base 1120 and the second circuit element 1330 (such as the substrate 1327), and a part of it can be disposed between the movable assembly 1200 and the outer frame 1110 (such as the thirteenth segment portion 1323, the fourteenth segment portion 1324, the fifteenth segment portion 1325, and the sixteenth segment portion 1326).

[0202] In some embodiments, an additional damping element 1630 can be disposed between the first circuit element 1310 and the second movable portion 1220 to movably connect a part of the first circuit element 1310 and the second movable portion 1220. In some embodiments, as Figure 4DAs shown, the damping element 1630 can be disposed between the second movable portion 1220 and the thirteenth segment portion 1323, fourteenth segment portion 1324, fifteenth segment portion 1325, and sixteenth segment portion 1326. For example, it can be disposed at the portion where the first circuit element 1310 is bent to absorb vibrations, thereby avoiding damage to the bent portion of the first circuit element 1310. In some embodiments, the material of the damping element 1630 can include a flexible element, such as gel.

[0203] Figure 5B is a cross-sectional view of the first circuit element 1310. As Figure 5B shown, the first circuit element 1310 can include a plurality of conductive lines 1341, a plurality of protective layers 1342, and an insulating layer 1343. The protective layer 1342 can cover the conductive line 1341, and the plurality of conductive lines 1341 and the plurality of protective layers 1342 can be disposed in the same insulating layer 1343. The conductive line 1341 can include, for example, a conductive metal, while the protective layer 1342 and the insulating layer 1343 can include insulating materials, and the materials of the protective layer 1342 and the insulating layer 1343 can be different from each other. Thus, an electrical signal can be allowed to pass through the conductive line 1341 and be transmitted in the first circuit element 1310.

[0204] In some embodiments, as Figure 4A 、 Figure 5A shown, the conductive line 1341 can be exposed in the first circuit element 1310 at the second connection portion 1512 and the third connection portion 1513 to allow other elements to make electrical connections through the conductive line 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 line 1341 exposed at the second connection portion 1512, thereby allowing the optical element driving mechanism 1000 to cooperate with other elements. In addition, the third connection portion 1513 can be connected to the first coil 1411 or the second coil 1412 to supply energy to the first coil 1411 or the second coil 1412.

[0205] Figure 6A 、 Figure 6B 、 Figure 6C are partial enlarged views of the base 1120 when viewed from different directions, where Figure 6C is Figure 4A an enlarged view of the region R2 in Figure 4C 、 Figures 6A to 6CAs shown, the base 1120 may have a plurality of grooves 1121 located on the 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 through 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 side of the first groove portion 1122 connected to the bottom surface 1128 has a first width 1931, the side of the first groove portion 1122 connected to the connecting portion 1124 has a second width 1932, 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 to facilitate demolding when manufacturing the base 1120.

[0207] In some embodiments, the connecting 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, while 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 terminals 1125 of this circuit may be exposed on the base 1120, for example, may be exposed on the connecting portion 1124 of the base 1120. In some embodiments, a plurality of circuit terminals 1125 may be exposed on the same connecting portion 1124.

[0208] In some embodiments, the base 1120 may further have a plurality of grooves 1126 recessed from the outer surface 1127 and extending in the direction of the first axis 1911. Thereby, the surface area of the base 1120 can be increased, so that when using the adhesive element 1111 to join the outer frame 1110 and the base 1120, the adhesive strength can be increased. 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, such as Figure 6CAs shown, when calculated from the outer surface 1127, 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, 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] Figure 7A , Figure 7B , Figure 7C are schematic views of some components of the optical element driving mechanism 1000. As Figure 2D , Figure 2E , Figures 7A to 7C shown, the connecting component 1500 may include a first connecting element 1501, a second connecting element 1502, a third connecting element 1503, a fourth connecting element 1504, a fifth connecting element 1505, a sixth connecting element 1506, a seventh connecting element 1507, a first connecting portion 1511, a second connecting portion 1512, a third connecting portion 1513, and a fourth strengthening element 1514.

[0211] 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 by the fourth strengthening 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 accommodation space 1950 between the base 1120 and the second movable portion 1220.

[0212] In some embodiments, as 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 part 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 remaining part is located on the other side of the first virtual plane 1941.

[0213] In some embodiments, as Figure 2D , Figure 2E 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 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, on the first axis 1911, the fourth connecting element 1504 may have a first height 1921, the accommodating space 1950 may have a second height 1922, and the first height 1921 is less than the second height 1922. That is, the fourth connecting element 1504 is not usually used to support the second movable part 1220 and the base 1120, but when the second movable part 1220 is skewed, it can act as a stop element to prevent damage to the second movable part 1220.

[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, for example, ceramics. Thus, rolling can occur when the second movable part 1220 moves relative to the base 1120, so as to reduce the frictional force between the second movable part 1220 and the base 1120, making it easier for the second movable part 1220 to move. 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 skewing during operation, thereby increasing its optical performance.

[0216] In some embodiments, as Figure 2A , Figure 7A , Figure 7B 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 part 1220, and the sensing magnetic element 1610 may be disposed on the first movable part 1210. In some embodiments, the sensing elements 1601 and 1602 may respectively correspond to the first magnetic element 1421 and the second magnetic element 1422, and may partially overlap, for example, on the first axis 1911. The sensing element 1603 may correspond to the sensing magnetic element 1610 and may at least partially overlap, for example, on the third axis 1913.

[0217] In some embodiments, the sensing magnetic element 1610 may include, for example, a magnet, and the sensing elements 1601, 1602, and 1603 may include Hall effect sensors, magnetoresistance effect sensors (MR sensors), giant magnetoresistance effect sensors (GMR sensors), tunneling magnetoresistance effect sensors

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

[0219] Figure 8A , Figure 8B , Figure 8C , Figure 8D are schematic views of some components of the optical element driving mechanism 1000 when viewed from different directions, where the second movable part 1220 is further omitted. In some embodiments, as Figure 8B shown, the fourth strengthening element 1514 can be at least partially exposed from the first connecting part 1511, the second connecting part 1512, and the third connecting part 1513, and its material can include non-magnetic metal. Thus, the first connecting part 1511, the second connecting part 1512, and the third connecting part 1513 can be connected to each other through the fourth strengthening element 1514. In some embodiments, as Figure 2D , Figure 2E , Figure 8B shown, the fourth strengthening element 1514 can 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 part 1220, and does not overlap with the fourth connecting element 1504.

[0220] In addition, the fourth strengthening element 1514 can include a first end 1561 and a second end 1562, where the first end 1561 can be disposed on the first connecting part 1511 and at least partially exposed from the first connecting part 1511, and the second end 1562 can be disposed on the third connecting part 1513 and at least partially exposed from the third connecting part 1513. In some embodiments, the first end 1561 and the second end 1562 can extend in the same direction, for example, in the direction parallel to the second axis 1912.

[0221] In some embodiments, as Figure 2D , Figure 2E , Figure 8BAs shown, the first connecting portion 1511 may include a first recess 1515 and a fifth recess 1541, the second connecting portion 1512 may include a second recess 1516 and a sixth recess 1542, the third connecting 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 connecting element 1501 may be disposed in the first recess 1515, the second connecting element 1502 may be disposed in the second recess 1516, the third connecting element 1503 may be disposed in the third recess 1517, the fourth connecting element 1504 may be disposed in the fourth recess 1518, the fifth connecting element 1505 may be disposed in the fifth recess 1541, the sixth connecting element 1506 may be disposed in the sixth recess 1542, and the seventh connecting element 1507 may be disposed in the seventh recess 1543.

[0222] In some embodiments, in the direction in which the first axis 1911 extends, the first recess 1515 and the fifth recess 1541 may at least partially overlap, the second recess 1516 and the sixth recess 1542 may at least partially overlap, and the third recess 1517 and the seventh recess 1543 may at least partially overlap. That is to say, 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 recess surface 1551, the second recess surface 1552, the third recess surface 1553, and the fourth recess surface 1554 may face away from the base 1120, while the fifth recess surface 1555, the sixth recess surface 1556, and the seventh recess surface 1557 may face the base 1120, and their normal vectors may be parallel to the first axis 1911.

[0224] In some embodiments, as Figure 8B shown, when observed along the first axis 1911, the second recess 1516 and the third recess 1517 are arranged in a direction parallel to the third axis 1913, while the first recess 1515 and the second recess 1516 are arranged in a direction parallel to the second axis 1912. In some embodiments, as Figure 8B shown, in the direction in which the second axis 1912 extends, the first recess surface 1551 has a first dimension 1961, the second recess surface 1552 has a second dimension 1962, the third recess surface 1553 has a third dimension 1963, the fourth recess surface 1554 has a fourth dimension 1964, and the first dimension 1961 may be the same as the second dimension 1962. The first dimension 1961 may be different from the third dimension 1963 and the fourth dimension 1964, and the third dimension 1963 is different from the fourth dimension 1964. For example, the first dimension 1961 may be smaller than the third dimension 1963, and the third dimension 1963 may be smaller than the fourth dimension 1964. Thereby, it is possible to avoid the optical element driving mechanism 1000 being unable to be assembled due to tolerances.

[0225] In some embodiments, lubricating elements 1620 (such as 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 frictional force between the connecting assembly 1500, the second movable part 1220, and the base 1120.

[0226] In some embodiments, additional strengthening elements may be added to the second movable part 1220 to enhance its mechanical strength and simultaneously have the function of magnetic conduction. For example, as Figure 7C , Figures 8A to 8D shown, the second movable part 1220 may include a main body 1224, and the main body 1224 may include a first strengthening element 1221, a second strengthening element 1222, and a third strengthening element 1223. In some embodiments, the first strengthening element 1221, the second strengthening element 1222, and the third strengthening element 1223 may be spaced apart from each other and may be made of a magnetically conductive metal material. It should be noted that, in some embodiments, the first strengthening element 1221, the second strengthening element 1222, and the third strengthening element 1223 may be at least partially exposed from the main body 1224.

[0227] In some embodiments, as Figure 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, 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 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 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 part 1220 can be enhanced, and the direction of the magnetic field lines of the magnetic assembly 1420 can also 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. Thus, the direction of the movable part relative to the fixed part can be made more stable when moving, so as to obtain a better imaging effect.

[0229] The special relative positions and size relationships of the various elements disclosed in the present disclosure can not only make the driving mechanism thinner in a specific direction and smaller as a whole, but also further improve the optical quality of the system (such as shooting quality or depth sensing accuracy, etc.) by matching different optical modules. Furthermore, a multiple anti-vibration system is achieved by using each optical module to greatly improve the anti-shake effect.
