[0134] In some embodiments, the outer frame 1110 and the base 1120 of the fixed portion 1100 can be combined with each other to form a housing of the optical element driving mechanism 1000, and other elements of the optical element driving mechanism 1000 can be disposed in the housing formed by the outer frame 1110 and the base 1120 to protect the other elements.

[0135] In some embodiments, the first movable portion 1210 and the second movable portion 1220 of the movable portion 1200 can be disposed in the fixed portion 1100 and can move relative to the fixed portion 1100. That is, the first movable portion 1210 and the second movable portion 1220 can be movably connected to the fixed portion 1100. In addition, the first movable portion 1210 can also move relative to the second movable portion 1220.

[0136] In some embodiments, the driving assembly 1300 can be used to drive the first movable portion 1210 and the second movable portion 1220 to move relative to the fixed portion 1100 to achieve the effects of Auto Focus (AF) or Optical Image Stabilization (OIS). In some embodiments, the first movable portion 1210 can move along the Z-axis, and the second movable portion 1220 can move along the X-axis and the Y-axis.

[0137] In some embodiments, the first circuit component 1500, such as a Printed Circuit Board (PCB), can be disposed on the second movable portion 1220, such as being adhered to the second movable portion 1220, to electrically connect other components (such as the driving component 1300) in the optical element driving mechanism 1000 and external devices, to provide electrical signals. Thus, the movement of the movable portion 1200 in the X, Y, and Z axes can be controlled, and the functions of auto-focusing (AF) or optical image stabilization (OIS) can be achieved. The driving component 1300 can be adhered to the first circuit component 1500.

In some embodiments, the first shock-absorbing element 1151 and the second shock-absorbing element 1152 can include, for example, gel.

[0141] ​A first stop element 1141 may be provided at a corner of the optical element driving mechanism 1000 to limit the range of motion of the first movable part 1210 and the second movable part 1220. For example, the second movable part 1220 may include a first body 1221, and the first stop element 1141 may be fixedly disposed on the first body 1221. The first body 1221 and the first stop element 1141 may include dielectric materials, and the first body 1221 and the first stop element 1141 may include different materials.

[0145] In some embodiments, the first intermediate element 1410 and the second intermediate element 1420 may be fixed to the first support portion 1710 and the second support portion 1720, respectively, and are movably connected to the first corresponding portion 1730 and the second corresponding portion 1740 by frictional contact, respectively. In other embodiments, the first intermediate element 1410 and the second intermediate element 1420 may be fixed to the first corresponding portion 1730 and the second corresponding portion 1740, respectively, and are movably connected to the first support portion 1710 and the second support portion 1720 by frictional contact, depending on design requirements. In some embodiments, the first intermediate element 1410 and the second intermediate element 1420 may have a columnar shape and extend along the Z-axis direction. Thus, the first movable portion 1210 can move relative to the second movable portion 1220 along the Z-axis via the support assembly 1400.

[0146] In some embodiments, such as FIG. 4A as well as FIG. 4B As shown, the second movable portion 1220 may have a first groove 1231 and a second groove 1232, respectively for accommodating the first intermediate element 1410 and the second intermediate element 1420. The first groove 1231 and the second groove 1232 may extend along a first axis 1901, which may be, for example, an axis parallel to the Z-axis. In some embodiments, the first intermediate element 1410 and the second intermediate element 1420 may have different lengths; for example, on the first axis 1901, the length of the first intermediate element 1410 may be greater than the length of the second intermediate element 1420. Therefore, the first groove 1231 and the second groove 1232 may also have different lengths; for example, the length 1911 of the first groove 1231 may be greater than the length 1912 of the second groove 1232.

[0147] In some embodiments, the first trench 1231 may include a first starting end 1411 and a first ending end 1412, while the second trench 1232 may include a second starting end 1421 and a second ending end 1422. The first starting end 1411 and the first ending end 1412 may be located on both sides of the first trench 1231, while the second starting end 1421 and the second ending end 1422 may be located on both sides of the second trench 1232. On the first axis 1901 (Z-axis), there may be a non-zero distance 1913 between the first starting end 1411 and the second starting end 1421, and a non-zero distance 1914 between the first ending end 1412 and the second ending end 1422. In other words, on the first shaft 1901, there can be a height difference between the first starting end 1411 and the second starting end 1421, and there can also be a height difference between the first terminal end 1412 and the second terminal end 1422, thereby controlling the connection method of the first intermediate element 1410 and the second intermediate element 1420 relative to the second movable part 1220. For example, the connection method between the first intermediate element 1410 and the second movable part 1220 can be approximated as two-point support, while the connection method between the second intermediate element 1420 and the second movable part 1220 can be approximated as single-point support, thereby approximating three-point support, to further improve the stability of the overall structure.

[0148] In some embodiments, such as FIG. 5B As shown, the first corresponding part 1730 may include a first contact surface 1731, a second contact surface 1732, a third contact surface 1733, a fourth contact surface 1734, a first connecting surface 1735, a second connecting surface 1736, and a third connecting surface 1737. The first connecting surface 1735 may be located between the first contact surface 1731 and the second contact surface 1732, and connects the first contact surface 1731 and the second contact surface 1732. The second connecting surface 1736 may be located between the third contact surface 1733 and the fourth contact surface 1734, and connects the third contact surface 1733 and the fourth contact surface 1734. The third connecting surface 1737 may be located between the first connecting surface 1735 and the second connecting surface 1736, and connects the first connecting surface 1735 and the second connecting surface 1736. The first contact surface 1731, the second contact surface 1732, the third contact surface 1733, and the fourth contact surface 1734 may be spaced apart from each other.

[0149] In some embodiments, the first contact surface 1731 and the third contact surface 1733 may be arranged along the first axis 1901, and the second contact surface 1732 and the fourth contact surface 1734 may also be arranged along the first axis 1901. In some embodiments, the first intermediate element 1410 may directly contact the first contact surface 1731, the second contact surface 1732, the third contact surface 1733, and the fourth contact surface 1734, and is spaced apart from the first connecting surface 1735, the second connecting surface 1736, and the third connecting surface 1737, for example, with a gap between them. That is, one end of the first intermediate element 1410 may directly contact the first contact surface 1731 and the second contact surface 1732, while the other end may directly contact the third contact surface 1733 and the fourth contact surface 1734. In other words, on the first axis 1901, the two ends of the first intermediate element 1410 may approximately rest on the first corresponding portion 1730 at two points.

[0150] In some embodiments, such as FIG. 5C As shown, the second corresponding portion 1740 may include a first buffer surface 1741, a second buffer surface 1742, a protrusion 1743, and a fifth contact surface 1744. The protrusion 1743 may protrude toward the second intermediate element 1420 and may be located between the first buffer surface 1741 and the second buffer surface 1742, while the fifth contact surface 1744 may be located on the protrusion 1743 and between the first buffer surface 1741 and the second buffer surface 1742. In some embodiments, the first buffer surface 1741, the second buffer surface 1742, and the fifth contact surface 1744 may face the second intermediate element 1420 and may have a normal vector in the same direction (e.g., parallel to the X-axis). The fifth contact surface 1744 may directly contact the second intermediate element 1420, while the first buffer surface 1741 and the second buffer surface 1742 may be spaced apart from the second intermediate element 1420. Therefore, the second intermediate element 1420 can be approximately supported on the second corresponding part 1740 at a single point, so that the first intermediate element 1410 and the second intermediate element 1420 can be approximately supported on the first movable part 1210 at three points, thereby further improving the stability of the overall structure.

That is, the first coil 1301 can have an elongated structure and extend along the second axis 1902. The second coil 1302 can have an elongated structure and extend along the third axis 1903. The third coil 1303 can have an elongated structure and extend along the second axis 1902.

[0154] In some embodiments, on the second axis 1902, the first positioning element 1171 has a maximum size 1921, and the second positioning element 1172 has a maximum size 1922. On the third axis 1903, the third positioning element 1173 may have a maximum size 1923, and the fourth positioning element 1174 may have a maximum size 1924. In some embodiments, the maximum size 1921 is different from the maximum sizes 1923 and 1924, and the maximum size 1922 is also different from the maximum sizes 1923 and 1924.

[0155] In some embodiments, such as FIG. 2A , FIG. 2B ,as well as FIG. 6 As shown, a first reinforcing element 1321, a second reinforcing element 1322, and a third reinforcing element 1323 can be respectively provided on the first magnetic element 1311, the second magnetic element 1312, and the third magnetic element 1313. For example, the first reinforcing element 1321, the second reinforcing element 1322, and the third reinforcing element 1323 can at least partially overlap with the first magnetic element 1311, the second magnetic element 1312, and the third magnetic element 1313 on the Z-axis. In addition, the first reinforcing element 1321, the second reinforcing element 1322, and the third reinforcing element 1323 can correspond to the first coil 1301, the second coil 1302, and the third coil 1303, respectively. For example, the first reinforcing element 1321, the second reinforcing element 1322, and the third reinforcing element 1323 can at least partially overlap with the first coil 1301, the second coil 1302, and the third coil 1303 on the Z-axis. In some embodiments, the winding axes of the first coil 1301, the second coil 1302, and the third coil 1303 can all be parallel to the Z-axis.

[0157] FIG. 7 is a schematic view of some elements of the optical element driving mechanism 1000. As shown in FIG. 6 , FIG. 7 The optical element driving mechanism 1000 can further include a first electronic element 1341 disposed between the first positioning element 1171 and the second positioning element 1172. In some embodiments, the first electronic element 1341 can include, for example, a Hall Sensor, a Magnetoresistance Effect Sensor (MR Sensor), a Giant Magnetoresistance Effect Sensor (GMR Sensor), a Tunneling Magnetoresistance Effect Sensor (TMR Sensor), or a Fluxgate Sensor. The first electronic element 1341 can also include an integrated circuit element for control purposes.

[0158] As shown in FIG. 6 , FIG. 7 The optical element driving mechanism 1000 can further include a first protection element 1331 disposed between the first positioning element 1171 and the second positioning element 1172 and can directly contact the first coil 1301, the first electronic element 1341, the first positioning element 1171, and the second positioning element 1172. The first protection element 1331 can include, for example, glue, which can be used to fill the gap between the first coil 1301, the first positioning element 1171, and the second positioning element 1172 and can also be used to protect the first electronic element 1341. In some embodiments, the shortest distance 1931 between the first protection element 1331 and the first magnetic element 1311 is greater than the shortest distance 1932 between the first positioning element 1171 and the first magnetic element 1311, that is, when the first magnetic element 1311 moves in the Z-axis, the first magnetic element 1311 will first hit the first positioning element 1171 before the first magnetic element 1311 directly contacts the first protection element 1331, which can be used to avoid the first protection element 1331 and the first magnetic element 1311 from colliding and being damaged, so as to further improve the durability of the optical element driving mechanism 1000.

[0159] In some embodiments, as shown in FIG. 6As shown, the optical element driving mechanism 1000 can further include a second electronic element 1342, a third electronic element 1343 disposed between the third positioning element 1173 and the fourth positioning element 1174. The second electronic element 1342, the third electronic element 1343 can include similar elements as the aforementioned first electronic element 1341, and thus will not be repeated here. A second protection element 1332 can be disposed on the second electronic element 1342, the third electronic element 1343, for example, the second protection element 1332 can contact the second electronic element 1342, the third electronic element 1343, the third positioning element 1173, the fourth positioning element 1174 to protect the second electronic element 1342, the third electronic element 1343. The second protection element 1332 can include glue, for example.

[0160] In some embodiments, as shown in FIG. 1 1 1, the second positioning element 1 121 can include a fifth positioning element 1 175 and a sixth positioning element 1 176. The fifth positioning element 1 175 can be disposed on the second body 1 121, and the sixth positioning element 1 176 can be disposed on the third body 1 122. The fifth positioning element 1 175 can be connected to the sixth positioning element 1 176, for example, the fifth positioning element 1 175 and the sixth positioning element 1 176 can be connected by a connecting portion 1 177. FIG. 6 As shown, the third positioning portion 1 163 can further include a connecting portion 1 177 connecting the fifth positioning element 1 175 and the sixth positioning element 1 176. The connecting portion 1 177 can have a plate-like structure, and a third protection element 1333 can be disposed in a groove formed by the fifth positioning element 1 175, the sixth positioning element 1 176, and the connecting portion 1 177. The third protection element 1333 can include glue, for example, and can be used to protect the third coil 1303.

[0161] In some embodiments, on the third axis 1903, the maximum dimension 1941 of the second coil 1302 is different from the maximum dimension 1942 of the third coil 1303, for example, the maximum dimension 1941 can be greater than the maximum dimension 1942. That is, the driving force generated by the second coil 1302 and the second magnetic element 1312 can be greater than the driving force generated by the third coil 1303 and the third magnetic element 1313. Thus, the second coil 1302 and the second magnetic element 1312 can be designed to mainly drive the second movable portion 1220, and the third coil 1303 and the third magnetic element 1313 can be designed to prevent the second movable portion 1220 from flipping when in motion.

[0162] FIG. 8 is a schematic view of the base 1 120. As shown in FIG. 8 In some embodiments, the base 1 120 can include a second body 1 121, a third metal component 1 122 (also referred to as a circuit unit), and a second stop element 1 123. The third metal component 1 122 can be embedded in the second body 1 121 and partially exposed from the second body 1 121 to serve as a conductive circuit and to enhance structural strength. The second body 1 121 can include a dielectric material, for example, can include plastic. As shown in FIG. 3A to FIG. 3CAs shown, the first coil 1301 can be electrically connected to the third metal component 1122 (may also be referred to as a circuit unit) at the first electrical connection 1315, and the second coil 1302 can be electrically connected to the third metal component 1122 at the second electrical connection 1316. The first shock absorbing element 1151 can directly contact the first electrical connection 1315, and the second shock absorbing element 1152 can directly contact the second electrical connection 1316, to protect the first electrical connection 1315 and the second electrical connection 1316.

[0163] The second stop element 1123 can be disposed on the second body 1121 and the third metal component 1122 to limit the movement of the optical element, for example, directly or indirectly. The second stop element 1123 can have a dielectric material, and the second body 1121 and the second stop element 1123 can have different materials, for example, the Young's modulus of the second stop element 1123 can be lower than the Young's modulus of the second body 1121. In some embodiments, the second stop element 1123 can include rubber. In some embodiments, the first stop element 1141 and the second stop element 1123 can include the same material, and the first body 1221 and the second body 1121 can also have the same material.

[0164] FIG. 9A is a schematic diagram of some elements of the optical element driving mechanism 1000. In some embodiments, as shown in FIG. 2A , FIG. 9A The second movable portion 1220 can also include a first metal component 1222 disposed in the first body 1221, as shown. In some embodiments, the first metal component 1222 can include a metal material and be disposed in the first body 1221, for example, partially embedded in the first body 1221 and partially exposed to the first body 1221. The first metal component 1222 can correspond to the first circuit component 1500, for example, at least partially overlap in the X direction. The first metal component 1222 can be used to enhance the mechanical strength of the second movable portion 1220.

[0165] In some embodiments, the optical element driving mechanism 1000 can further include a first amplification element 1223. The first amplification element 1223 can be positioned between the first circuit assembly 1500 and the first metal assembly 1222, and can have a metallic material. In some embodiments, the first metal assembly 1222 and the first amplification element 1223 can have different materials, for example, the permeability of the first amplification element 1223 can be greater than the permeability of the first metal assembly 1222, so as to enhance the driving strength of the fourth coil 1304 and the fourth magnetic element 1314 through the first amplification element 1223. In some embodiments, as shown in FIG. 2A , the fourth coil 1304 can be disposed on the second movable part 1220, and the fourth magnetic element 1314 can be disposed on the first movable part 1210, so as to drive the first movable part 1210 to move relative to the second movable part 1220, for example, to move parallel to the Z-axis, through the fourth coil 1304 and the fourth magnetic element 1314.

[0166] In some embodiments, as shown in FIG. 2A , FIG. 9A , the optical element driving mechanism 1000 can further include a first connecting element 1224. The first connecting element 1224 can directly contact the first metal assembly 1222, the first amplification element 1223, and the first circuit assembly 1500. The first connecting element 1224, for example, can include glue, and can be used to fix the first amplification element 1223 on the first circuit assembly 1500. In some embodiments, the first metal assembly 1222 has a first accommodating portion 1225, which has a recessed structure, and is used to accommodate the first amplification element 1223, and the first connecting element 1224 is also at least partially accommodated in the first accommodating portion 1225.

[0167] FIG. 9B is a schematic diagram of some elements of the optical element driving mechanism 1000. As shown in FIG. 9B , the second movable part 1220 can further include a second metal assembly 1226, which has a metallic material, is disposed on the first body 1221, for example, can be partially embedded in the first body 1221, and partially exposed from the first body 1221. The second metal assembly 1226 can be electrically connected to the driving assembly 1300, for example, can include a first electrical contact 1228, which is electrically connected to the driving assembly 1300 (for example, is electrically connected to the fourth coil 1304).

[0168] The first circuit assembly 1500 may have a plate-like structure, and in a first direction parallel to the first circuit assembly 1500 (e.g., the Y direction), the first metal assembly 1222 and the second metal assembly 1226 at least partially overlap. Furthermore, the optical element driving mechanism 1000 may also include a first electrical connection element 1227 disposed at a first electrical contact 1228, for example, overlapping in the X direction. In the first direction, the first electrical connection element 1227 and the first metal assembly 1222 may at least partially overlap.

[0169] In addition, such as FIG. 3A to FIG. 3C As shown, the optical element driving mechanism 1000 may also have a third circuit assembly 1350 located at a corner of the optical element driving mechanism 1000 and extending along the Z-axis. The first stop element 1141 may have a first groove 1142 corresponding to the third circuit assembly 1350; for example, the third circuit assembly 1350 may be accommodated in the first groove 1142, and the first groove 1142 is spaced apart from the first stop element 1141 to protect the third circuit assembly 1350. Furthermore, the second movable portion 1220 may also have a second groove 1229 corresponding to the third circuit assembly 1350; for example, the third circuit assembly 1350 may be accommodated in the second groove 1229, and the second groove 1229 is spaced apart from the first stop element 1141 to protect the third circuit assembly 1350. When viewed along the main axis 1900, the first groove 1142 and the second groove 1229 may be located at the first corner 1131. In some embodiments, the first groove 1142 may be continuously connected to the second groove 1229. Thus, an electrical signal can be transmitted from one side of the optical element drive mechanism 1000 to the other side via a third circuit assembly 1350 extending along the Z-axis.

[0170] In some embodiments, the second circuit assembly 1600 is movable relative to the second metal assembly 1226 and can be electrically connected to each other. That is, the second circuit assembly 1600, electrically connected to an external module (not shown), can be electrically connected to other components via the second metal assembly 1226. The second circuit assembly 1600 can be electrically connected to a third circuit assembly 1350 and can be electrically connected to an external circuit (not shown) via the third circuit assembly 1350, and the second metal assembly 1226 can also be electrically connected to this external circuit via the third circuit assembly 1350. In other words, the second metal assembly 1226 and the second circuit assembly 1600 can share the third circuit assembly 1350 to transmit signals, thereby reducing the number of required components, saving costs, and achieving miniaturization.

[0171] In summary, the optical element driving mechanism provided by the embodiments of the present disclosure includes a first movable part, a fixed part and a driving assembly. The movable part is used to connect an optical element. The movable part is movable relative to the fixed part. The driving assembly is used to drive the first movable part to move relative to the fixed part. Thus, the effects of automatic focusing, optical anti-shake, zooming and the like can be achieved, and miniaturization can also be achieved.

[0172] The special relative positions and size relationships of the elements disclosed in the present disclosure not only make the driving mechanism thin in a specific direction and small in size as a whole, but also make the system further improve the optical quality (such as the shooting quality or the depth sensing accuracy) by matching different optical modules. Furthermore, the multiple anti-shake systems of the optical modules are used to greatly improve the effect of anti-shake.
