[0139] First, please refer to Figure 1 , Figure 1 which is a schematic diagram of an electronic device 1 according to some embodiments of the present disclosure. As Figure 1 shown, an optical element driving mechanism 100 according to some embodiments of the present disclosure can be installed in an electronic device 1 for taking pictures or photographs, where the aforementioned electronic device 1 can be, for example, a smart phone or a digital camera, but the present disclosure is not limited thereto. It should be noted that Figure 1 the positional and size relationships between the optical element driving mechanism 100 and the electronic device 1 shown in

[0140] Please refer to Figure 2 and Figure 3 . Figure 2 which is a schematic diagram of an optical element driving mechanism 100, a first optical element OE1, and a second optical element OE2 according to some embodiments of the present disclosure, where the outer frame 111 is shown in dashed lines. Figure 3 which is an exploded view of an optical element driving mechanism 100, a first optical element OE1, and a second optical element OE2 according to some embodiments of the present disclosure.

[0141] The optical element driving mechanism 100 may include a fixed part 110, a first movable part 120, a first driving component 130, a second movable part 140, a second driving component 145, a first support component 150, a second support component 155, a third support component 160, a stabilizing component 170, a reinforcing component 175, a circuit component 180, and a connecting component 190.

[0142] The fixed part 110 may include an outer frame 111, a base 112, and a fixed part magnetic conductive element 113. The outer frame 111 is disposed on the base 112, and the outer frame 111 and the base 112 may be connected to each other to form an internal space for accommodating other elements of the optical element driving mechanism 100 or the first optical element OE1 and the second optical element OE2.

[0143] As Figure 2 shown, a light ray L may enter the second optical element OE2 from the outside of the optical element driving mechanism 100 along a first direction D1. The second optical element OE2 refracts and / or reflects the light ray L from the first direction D1 to be incident on the first optical element OE1 along the optical axis OA (which may also be a third direction D3 perpendicular to the first direction D1).

[0144] The first movable part 120 may be connected to the first optical element OE1, and the first movable part 120 may move relative to the fixed part 110. For example, the first movable part 120 may move along the optical axis OA relative to the fixed part 110, and the first optical element OE1 may move along the optical axis OA relative to the fixed part 110 as the first movable part 120 moves.

[0145] The first driving component 130 may drive the first movable part 120 to move relative to the fixed part 110. The first driving component 130 may include a first driving magnet 131, a first driving coil 132, a first magnetic isolation element 133, a second driving magnet 134, a second driving coil 135, and a second magnetic isolation element 136.

[0146] The first driving magnet 131 and the second driving magnet 134 may be disposed on the first movable part 120, and the first driving coil 132 and the second driving coil 135 may be disposed on the base 112, such that when the first driving coil 132 and the second driving magnet 134 receive current from the circuit component 180, the first driving magnet 131 and the second driving magnet 134 will drive the first movable part 120 to move along the optical axis OA relative to the fixed part 110.

[0147] The first magnetic isolation element 133 corresponds to the first driving magnet 131, and the second magnetic isolation element 136 corresponds to the second driving magnet 134. For example, the first magnetic isolation element 133 can be disposed adjacent to the first driving magnet 131 or attached to the first driving magnet 131, and the second magnetic isolation element 136 can be disposed adjacent to the second driving magnet 134 or attached to the second driving magnet 134.

[0148] The first magnetic isolation element 133 and the second magnetic isolation element 136 can be made of a magnetic conductive material to avoid magnetic force leakage of the first driving magnet 131 and / or the second driving magnet 134, thereby avoiding unwanted magnetic force effects on other elements of the optical element driving mechanism 100 or external devices.

[0149] The second movable part 140 can be connected to the second optical element OE2, and the second movable part 140 can move relative to the fixed part 110. For example, the second movable part 140 can rotate relative to the fixed part 110 about a first direction D1 and / or a second direction D2 perpendicular to the optical axis OA, and the second optical element OE2 can rotate as the second movable part 140 rotates relative to the fixed part 110 about the first direction D1 and / or the second direction D2.

[0150] The second driving assembly 145 drives the second movable part 140 to move relative to the fixed part 110. When the second driving assembly 145 receives current from the circuit assembly 180, the second driving assembly 145 will drive the second movable part 140 to rotate relative to the fixed part 110 about the first direction D1 and / or the second direction D2.

[0151] The first support assembly 150, the second support assembly 155, and the third support assembly 160 can support the first movable part 120 so that the first movable part 120 can move along the optical axis OA relative to the fixed part 110.

[0152] The stabilizing assembly 170 stabilizes the first movable part 120. The stabilizing assembly 170 includes a first stabilizing element 171 and a second stabilizing element 172.

[0153] The reinforcing assembly 175 is made of a metal material, and the reinforcing assembly 175 can be embedded in the base 112 to enhance the structure of the base 112.

[0154] The circuit assembly 180 is directly or indirectly connected to an external circuit to supply current to other elements of the optical element driving mechanism 100, such as the first driving coil 132 and the second driving coil 135 of the first driving assembly 130 and the second driving assembly 145.

[0155] Please refer to Figure 4 , Figure 4A cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure along Figure 2 line A-A'.

[0156] As Figure 4 shown, when viewed along a first direction D1 perpendicular to the optical axis OA, the fixing portion 110 having a polygonal structure further includes a first side 110a1 and a second side 110a2. The first side 110a1 and the second side 110a2 of the fixing portion 110 extend along the optical axis OA. When viewed along the first direction D1, the first side 110a1 and the second side 110a2 of the fixing portion 110 are respectively located on both sides of the optical axis OA.

[0157] The first driving magnet 131, the first driving coil 132, and the first magnetic isolation element 133 are located between the optical axis OA and the first side 110a1. Moreover, the distances between the first driving magnet 131, the first driving coil 132, and the first magnetic isolation element 133 and the first side 110a1 are less than the distances between the first driving magnet 131, the first driving coil 132, and the first magnetic isolation element 133 and the second side 110a2. That is to say, the first driving magnet 131, the first driving coil 132, and the first magnetic isolation element 133 are arranged close to the first side 110a1 and far from the second side 110a2.

[0158] The second driving magnet 134, the second driving coil 135, and the second magnetic isolation element 136 are located between the optical axis OA and the second side 110a2. Moreover, the distances between the second driving magnet 134, the second driving coil 135, and the second magnetic isolation element 136 and the second side 110a2 are less than the distances between the second driving magnet 134, the second driving coil 135, and the second magnetic isolation element 136 and the first side 110a1. That is to say, the second driving magnet 134, the second driving coil 135, and the second magnetic isolation element 136 are arranged close to the second side 110a2 and far from the first side 110a1.

[0159] When a first driving current from the circuit assembly 180 is input into the first driving coil 132 of the first driving assembly 130, the first driving assembly 130 generates a first driving force (represented by an arrow) F1 and applies the force to a first force receiving portion 120' of the first movable portion 120.

[0160] When observed along the first direction D1, the first force-receiving portion 120' is located between the first side 110a1 of the fixed portion 110 and the optical axis OA. It can be conceived that when observed along the first direction D1, the first force-receiving portion 120' and the first driving magnet 131 overlap each other, so that the first driving force F1 can stably and effectively drive the first movable portion 120. Therefore, the distance between the first force-receiving portion 120' and the first side 110a1 is less than the distance between the first force-receiving portion 120' and the second side 110a2. That is to say, the first force-receiving portion 120' is close to the first side 110a1 and far from the second side 110a2.

[0161] When a first driving current from the circuit component 180 is input to the second driving coil 135 of the first driving component 130, the first driving component 130 generates a second driving force (indicated by an arrow) F2 and applies a force to a second force-receiving portion 120" of the first movable portion 120.

[0162] When observed along the first direction D1, the second force-receiving portion 120" is located between the second side 110a2 of the fixed portion 110 and the optical axis OA. It can be conceived that when observed along the first direction D1, the second force-receiving portion 120" and the second driving magnet 134 overlap each other, so that the second driving force F2 can stably and effectively drive the first movable portion 120. Therefore, the distance between the second force-receiving portion 120" and the second side 110a2 is less than the distance between the second force-receiving portion 120" and the first side 110a1. That is to say, the second force-receiving portion 120" is close to the second side 110a2 and far from the first side 110a1.

[0163] According to some embodiments of the present disclosure, the magnetic force intensity of the first driving magnet 131 is different from the magnetic force intensity of the second driving magnet 134. Specifically, according to some embodiments of the present disclosure, the magnetic force intensity of the first driving magnet 131 is greater than the magnetic force intensity of the second driving magnet 134.

(In other words, the first magnetic shielding portion 1331 and the second magnetic shielding portion 1332 of the first magnetic shielding element do not face the first direction D1.) However, the first magnetic shielding portion 1331 of the first magnetic shielding element is not parallel to the second magnetic shielding portion 1332 of the first magnetic shielding element. Specifically, the first magnetic shielding portion 1331 of the first magnetic shielding element is perpendicular to the optical axis OA, and the second magnetic shielding portion 1332 of the first magnetic shielding element is perpendicular to the second direction D2. That is to say, the first magnetic shielding portion 1331 of the first magnetic shielding element is perpendicular to the second magnetic shielding portion 1332 of the first magnetic shielding element.

[0168] The first surface 1311 of the first driving magnet faces the first driving coil 132, and the first surface 1311 of the first driving magnet is perpendicular to the second direction D2.

[0169] The second surface 1312 of the first driving magnet faces the first magnetic shielding portion 1331 of the first magnetic shielding element 133, and the second surface 1312 of the first driving magnet is perpendicular to the optical axis OA.

[0178] Please continue to refer to Figure 4 , the second driving magnet 134 includes a first surface 1341 of the second driving magnet, a second surface 1342 of the second driving magnet, a third surface 1343 of the second driving magnet, and a fourth surface 1344 of the second driving magnet.

[0179] When observed along the first direction D1, the second magnetic shielding element 136 has an L shape, and the second magnetic shielding element 136 includes a first magnetic shielding portion 1361 of the second magnetic shielding element and a second magnetic shielding portion 1362 of the second magnetic shielding element.

[0180] The first magnetic shielding portion 1361 of the second magnetic shielding element and the second magnetic shielding portion 1362 of the second magnetic shielding element have a plate-like structure, and both the first magnetic shielding portion 1361 of the second magnetic shielding element and the second magnetic shielding portion 1362 of the second magnetic shielding element are parallel to the first direction D1 (in other words, the first magnetic shielding portion 1361 of the second magnetic shielding element and the second magnetic shielding portion 1362 of the second magnetic shielding element do not face the first direction D1). However, the first magnetic shielding portion 1361 of the second magnetic shielding element is not parallel to the second magnetic shielding portion 1362 of the second magnetic shielding element. Specifically, the first magnetic shielding portion 1361 of the second magnetic shielding element is perpendicular to the optical axis OA, and the second magnetic shielding portion 1362 of the second magnetic shielding element is perpendicular to the second direction D2. That is to say, the first magnetic shielding portion 1361 of the second magnetic shielding element is perpendicular to the second magnetic shielding portion 1362 of the second magnetic shielding element.

[0181] The first surface 1341 of the second driving magnet faces the second driving coil 135, and the first surface 1341 of the second driving magnet is perpendicular to the second direction D2.

[0182] The second surface 1342 of the second driving magnet faces the first magnetic shielding portion 1361 of the second magnetic shielding element 136, and the second surface 1342 of the second driving magnet is perpendicular to the optical axis OA.

[0183] The third surface 1343 of the second driving magnet faces the second magnetic shielding portion 1362 of the second magnetic shielding element 136, and the third surface 1343 of the second driving magnet is perpendicular to the second direction D2.

[0184] The second magnetic shielding element 136 does not correspond to the fourth surface 1344 of the second driving magnet, and the fourth surface 1344 of the second driving magnet is perpendicular to the optical axis OA.

[0185] The first magnetic shielding portion 1361 of the second magnetic shielding element is between the second driving magnet 134 and the second driving assembly 145.

[0186] When observed along the optical axis OA, at least a part of the first magnetic shielding portion 1361 of the second magnetic shielding element overlaps with the second driving magnet 134.

[0189] When observed along the direction (the second direction D2) perpendicular to the first surface 1341 of the second driving magnet, the first magnetic shielding portion 1361 of the second magnetic shielding element does not overlap with the second driving magnet 134.

[0190] When observed along the direction (the second direction D2) perpendicular to the first surface 1341 of the second driving magnet, at least a part of the second magnetic shielding portion 1362 of the second magnetic shielding element overlaps with the second driving magnet 134.

[0191] Please refer to Figure 5 , Figure 5 is a cross-sectional view taken along the B-B' line of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure. Figure 2 of.

[0192] The first support assembly 150 includes a first intermediate element 151 and a first support portion 152. The first intermediate element 151 may have a spherical shape. For example, the first intermediate element 151 may be a ball. The first support portion 152 corresponds to the first intermediate element 151, and the first intermediate element 151 can move relative to the first support portion 152. For example, the first intermediate element 151 can move along the optical axis OA relative to the first support portion 152.

[0193] The first support portion 152 may be located on the first movable portion 120. The first support portion 152 includes a first support portion first surface 1521 and a first support portion second surface 1522. The first support portion first surface 1521 and the first support portion second surface 1522 face different directions, and both the first support portion first surface 1521 and the first support portion second surface 1522 are in direct contact with the first intermediate element 151.

[0194] When viewed along the first direction D1, the first support assembly 150 is located between the first side 110a1 of the fixed portion 110 and the optical axis OA. The distance between the first support assembly 150 and the first side 110a1 is less than the distance between the first support assembly 150 and the second side 110a2. That is to say, the first support assembly 150 is close to the first side 110a1 and far from the second side 110a2.

[0195] Please refer to Figure 6 , Figure 6 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure along the Figure 2 C-C' line.

[0196] The second support assembly 155 includes a second intermediate element 156 and a second support portion 157. The second intermediate element 156 may have a spherical shape. For example, the second intermediate element 156 may be a ball. The second support portion 157 corresponds to the second intermediate element 156, and the second intermediate element 156 can move relative to the second support portion 157. For example, the second intermediate element 156 can move along the optical axis OA relative to the second support portion 157.

[0197] The second support portion 157 may be located on the first movable portion 120. The second support portion 157 includes a second support portion surface 1571 and a second support portion opening 1572. The second support portion surface 1571 directly contacts the second intermediate element 156. The second support portion surface 1571 faces a different direction from the first support portion first surface 1521 and the first support portion second surface 1522.

[0198] The second support portion opening 1572 is adjacent to the second support portion surface 1571, so that the second support portion surface 1571 is "broken" at a position close to the second side 110a2 of the fixed portion 110.

[0199] In this way, it can help to assemble the optical element driving mechanism 100. And the optical element driving mechanism 100 can be made lighter and smaller.

[0200] When viewed along the first direction D1, the second support assembly 155 is located between the second side 110a2 of the fixed portion 110 and the optical axis OA. The distance between the second support assembly 155 and the second side 110a2 is less than the distance between the second support assembly 155 and the first side 110a1. That is to say, the second support assembly 155 is close to the second side 110a2 and far from the first side 110a1.

[0201] Please refer to Figure 7 , Figure 7A cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure along the Figure 2 D-D' line.

[0202] The third support assembly 160 includes a third intermediate element 161 and a third support portion 162. The third intermediate element 161 may have a spherical shape. For example, the third intermediate element 161 may be a ball. The third support portion 162 corresponds to the third intermediate element 161, and the third intermediate element 161 can move relative to the third support portion 162. For example, the third intermediate element 161 can move along the optical axis OA relative to the third support portion 162.

[0203] The third support portion 162 may be located on the first movable portion 120. The third support portion 162 includes a first surface 1621 of the third support portion and a second surface 1622 of the third support portion. The first surface 1621 of the third support portion and the second surface 1622 of the third support portion face different directions, and both the first surface 1621 of the third support portion and the second surface 1622 of the third support portion are in direct contact with the third intermediate element 161.

[0204] When viewed along the first direction D1, the third support assembly 160 is located between the first side 110a1 of the fixed portion 110 and the optical axis OA. The distance between the third support assembly 160 and the first side 110a1 is less than the distance between the third support assembly 160 and the second side 110a2. That is, the third support assembly 160 is close to the first side 110a1 and away from the second side 110a2.

[0205] Please refer to Figure 5 , Figure 6 and Figure 7 simultaneously. The first surface 1521 of the first support portion and the first surface 1621 of the third support portion face the same direction; the first surface 1521 of the first support portion faces different directions from the surface 1571 of the second support portion and the second surface 1622 of the third support portion.

[0206] The second surface 1522 of the first support portion and the second surface 1622 of the third support portion face the same direction; the second surface 1522 of the first support portion faces different directions from the surface 1571 of the second support portion and the first surface 1621 of the third support portion.

[0207] The surface 1571 of the second support portion faces different directions from the first surface 1621 of the third support portion and the second surface 1622 of the third support portion.

[0208] In this way, the first intermediate element 151, the second intermediate element 156, and the third intermediate element 161 can be effectively restricted to prevent the first intermediate element 151, the second intermediate element 156, and the third intermediate element 161 from moving in an unwanted direction (e.g., the second direction D2).

[0209] Please continue to refer to Figure 5 , Figure 6 and Figure 7 . Since both the first surface 1521 and the second surface 1522 of the first support portion are in direct contact with the first intermediate element 151, the number of contact portions between the first support portion 152 and the first intermediate element 151 is 2; since the surface 1571 of the second support portion is in direct contact with the second intermediate element 156, the number of contact portions between the second support portion 157 and the second intermediate element 156 is 1; since both the first surface 1621 and the second surface 1622 of the third support portion are in direct contact with the third intermediate element 161, the number of contact portions between the third support portion 162 and the third intermediate element 161 is 2.

[0210] That is to say, the number of contact portions between the first support portion 152 and the first intermediate element 151 is different from the number of contact portions between the second support portion 157 and the second intermediate element 156; and the number of contact portions between the first support portion 152 and the first intermediate element 151 is greater than the number of contact portions between the second support portion 157 and the second intermediate element 156.

[0211] The number of contact portions between the first support portion 152 and the first intermediate element 151 is the same as the number of contact portions between the third support portion 162 and the third intermediate element 161, and the number of contact portions between the first support portion 152 and the first intermediate element 151 and the number of contact portions between the third support portion 162 and the third intermediate element 161 are both 2.

[0212] The number of contact portions between the third support portion 162 and the third intermediate element 161 is different from the number of contact portions between the second support portion 157 and the second intermediate element 156; and the number of contact portions between the third support portion 162 and the third intermediate element 161 is greater than the number of contact portions between the second support portion 157 and the second intermediate element 156. In this way, it can contribute to the assembly of the optical element driving mechanism 100. And the optical element driving mechanism 100 can be made more stable.

[0213] Please refer to Figure 8 , Figure 8 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure along the Figure 2 E-E' line.

[0214] The first stabilizing element 171 and the second stabilizing element 172 of the stabilizing assembly 170 may be magnets. The first stabilizing element 171 and the second stabilizing element 172 are disposed adjacent to the fixed magnetic element 113 made of a magnetic material, and the first stabilizing element 171 and the second stabilizing element 172 are disposed on the first movable part 120.

[0215] Therefore, the first stabilizing element 171 generates a first stabilizing force SF1 (represented by an arrow) on the first movable part 120 and acts on a first acting part 170', and the second stabilizing element 172 generates a second stabilizing force SF2 (represented by an arrow) on the first movable part 120 and acts on a second acting part 170".

[0216] As Figure 8 shown, when observed along the first direction D1, the first stabilizing element 171 and the first acting part 170' are located between the optical axis OA and the first side 110a1 of the fixed part 110; and, when observed along the first direction D1, the second stabilizing element 172 and the second acting part 170" are between the optical axis OA and the second side 110a2 of the fixed part 110.

[0217] According to some embodiments of the present disclosure, the magnetic force intensity of the first stabilizing element 171 is different from the magnetic force intensity of the second stabilizing element 172. Specifically, according to some embodiments of the present disclosure, the magnetic force intensity of the first stabilizing element 171 is greater than the magnetic force intensity of the second stabilizing element 172.

[0218] According to some embodiments of the present disclosure, the intensity of the first stabilizing force SF1 is different from the intensity of the second stabilizing force SF2. Specifically, according to some embodiments of the present disclosure, the intensity of the first stabilizing force SF1 is greater than the intensity of the second stabilizing force SF2.

[0219] Since the magnetic force intensity of the second driving magnet 134 and the magnetic force intensity of the second stabilizing element 172 adjacent to the second side 110a2 are less than the magnetic force intensity of the first driving magnet 131 and the magnetic force intensity of the first stabilizing element 171 adjacent to the first side 110a1; therefore, the magnetic force influence received by the second side 110a2 is less than the magnetic force influence received by the first side 110a1. In this way, it is possible to prevent external components at the first side 110a1 from being affected by the magnetic forces of the second driving magnet 134 and the second stabilizing element 172, and thus the external components can be disposed at the first side 110a1.

[0220] Please refer to Figure 9 , Figure 9 is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 according to some embodiments of the present disclosure along the Figure 2 F-F' line.

[0221] AsFigure 9 As shown, when viewed along the first direction D1, the distance between the first stabilizing element 171 and the second support assembly 155 is greater than the distances between the first stabilizing element 171 and the first support assembly 150 and between the first stabilizing element 171 and the third support assembly 160.

[0222] Furthermore, when viewed along the first direction D1, the first support assembly 150, the second support assembly 155, and the third support assembly 160 can form a triangle (shown by a dashed line) TA, and the first stabilizing element 171 is disposed within the triangle TA.

[0223] In this way, the first stabilizing force SF1 generated by the first stabilizing element 171 on the first movable part 120 (please refer to Figure 8 ) is also located within the triangle TA; thus, the first support assembly 150, the second support assembly 155, and the third support assembly 160 can stably support the first stabilizing force SF1, making the structure of the optical element driving mechanism 100 more stable.

[0224] Please continue to refer to Figure 9 , when viewed along the first direction D1, the distance between the second stabilizing element 172 and the second support assembly 155 is less than the distances between the second stabilizing element 172 and the first support assembly 150 and between the second stabilizing element 172 and the third support assembly 160.

[0225] Furthermore, since the second stabilizing force SF2 generated by the second stabilizing element 172 on the first movable part 120 (please refer to Figure 8 ) is relatively small, the second stabilizing element 172 may not be disposed within the triangle TA.

[0226] In this way, in addition to being able to balance the stabilizing force applied to the first movable part 120 to make the optical element driving mechanism 100 more stable, the manufacturing freedom of the optical element driving mechanism 100 can also be increased.

[0227] Please refer to Figure 10 , Figure 10 is Figure 8 a modified embodiment of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2.

[0228] In Figure 10 , the optical element driving mechanism 100 no longer has the second driving magnet 134, the second driving coil 135, the second magnetic isolation element 136, and / or the second stabilizing element 172. Therefore, the second side 110a2 of the fixing part 110 no longer has magnetic force, such that the second side 110a2 is not affected by the magnetic force.

[0229] In Figure 10In this case, the second driving force F2 is zero, and the second stabilizing force SF2 is also zero. The first movable part 120 is only driven by the first driving force F1, and the first movable part 120 is only fixed by the first stabilizing force SF1. In this way, the number of components of the optical element driving mechanism 100 can be reduced, and thus the optical element driving mechanism 100 can be made lighter and smaller. Moreover, the external components at the first side 110a1 can be prevented from being affected by magnetic force, so that the external components can be arranged at the first side 110a1.

[0230] Please refer to Figure 11 , Figure 11 which is a top view of the optical element driving mechanism 100, the external device 200, the first optical element OE1, and the second optical element OE2 according to some embodiments of the present disclosure.

[0231] When viewed along the first direction D1, the external device 200 can be arranged adjacent to the second side 110a2 without being affected by excessive magnetic interference. According to some embodiments of the present disclosure, the external device 200 can be another optical module, an antenna, a vibration motor, etc.

[0232] Please refer to Figure 12 and Figure 13 . Figure 12 which is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 along the Figure 2 G-G' line according to some embodiments of the present disclosure. Figure 13 which is a cross-sectional view of the optical element driving mechanism 100, the first optical element OE1, and the second optical element OE2 along the Figure 2 H-H' line according to some embodiments of the present disclosure.

[0233] The circuit assembly 180 includes a first lead 181, a second lead 182, a first circuit assembly connection portion 183, and a second circuit assembly connection portion 184. Moreover, the first circuit assembly connection portion 183 and the second circuit assembly connection portion 184 have a plate-like structure.

[0234] The circuit assembly 180 is arranged on the base 112 of the fixing portion 110. The base 112 includes a first groove 1121, a second groove 1122, and a groove spacing portion 1123. Moreover, the connection assembly 190 includes a first connection element 191, a second connection element 192, a third connection element 193, a fourth connection element 194, and a fifth connection element 195.

[0235] As Figure 12 and Figure 13As shown, the groove spacer 1123 is located between the first groove 1121 and the second groove 1122. The first groove 1121 corresponds to the first lead 181, and the second groove 1122 corresponds to the second lead 182. Specifically, the first lead 181 is disposed in the first groove 1121 and the second lead 182 is disposed in the second groove 1122.

[0236] The first groove 1121 and the second groove 1122 are formed in the surface of the base 112 facing away from the first movable portion 120 (parallel to the second direction D2, or the -X axis) (that is, the first groove 1121 and the second groove 1122 are formed in the outward-facing surface).

[0237] The base 112 is at least partially located between the first lead 181 and the first movable portion 120; and, the base 112 is at least partially located between the second lead 182 and the first movable portion 120. That is to say, it is emphasized that the first groove 1121 and the second groove 1122 do not penetrate the base 112 in the second direction D2.

[0238] In this way, the structure of the base 112 can be strengthened, and the first lead 181 and the second lead 182 can be accommodated simultaneously, making the electrical circuit of the optical element driving mechanism 100 more stable.

[0239] As Figure 12 and Figure 13 shown, the first lead 181 is connected to the first circuit component connection portion 183 of the circuit component 180 via the first connection element 191, and the second lead 182 is connected to the second circuit component connection portion 184 via the second connection element 192; in this way, the connection between the first lead 181 and the second lead 182 and the first circuit component connection portion 183 and the second circuit component connection portion 184 can be made more firm. The groove spacer 1123 is connected to the first circuit component connection portion 183 and the second circuit component connection portion 184 via the third connection element 193.

[0245] Please refer to Figure 14 , Figure 14 is a perspective view of the reinforcement assembly 175 of the optical element driving mechanism 100 according to some embodiments of the present disclosure.

[0246] As Figure 14 shown, the reinforcement assembly 175 includes a reinforcement body 1751, a first reinforcement portion 1752, a second reinforcement portion 1753, a first opening 1754, and a second opening 1755.

[0247] The reinforcement body 1751, the first reinforcement portion 1752, and the second reinforcement portion 1753 have a plate-like structure. The first opening 1754 is formed between the reinforcement body 1751 and the first reinforcement portion 1752. The second opening 1755 is formed between the reinforcement body 1751 and the second reinforcement portion 1753. A part (or material) of the base 112 can be embedded into the first opening 1754 and the second opening 1755 to make the combination of the base 112 and the reinforcement assembly 175 more stable.

[0248] Viewed along the direction perpendicular to the first direction D1, the upper surface of the first reinforcement portion 1752 is parallel to the reinforcement body 1751. The upper surface of the second reinforcement portion 1753 is not parallel to the reinforcement body 1751. The first reinforcement portion 1752 and the second reinforcement portion 1753 are not parallel.

[0249] As Figure 14As shown, in the thickness direction (first direction D1) of the reinforcement body 1751, there is a distance greater than zero between a center 1751C of the reinforcement body 1751 and a center 1752C of the first reinforcement portion 1752. That is to say, the reinforcement body 1751 and the first reinforcement portion 1752 are at different heights. The first reinforcement portion 1752 and the reinforcement body 1751 are integrally formed, and the first reinforcement portion 1752 is an arched structure protruding from the surface of the reinforcement body 1751 along the first direction D1.

[0250] In the thickness direction (first direction D1) of the reinforcement body 1751, there is a distance greater than zero between the center 1753C of the second reinforcement portion 1753 and a center 1752 of the first reinforcement portion 1752. That is to say, the first reinforcement portion 1752 and the second reinforcement portion 1753 are at different heights. The second reinforcement portion 1753 and the reinforcement body 1751 are integrally formed, and the second reinforcement portion 1753 is an arched structure protruding from the surface of the reinforcement body 1751 along a direction greater than 0 degrees with respect to the first direction D1. Since the first reinforcement portion 1752 and the second reinforcement portion 1753 have different angles and heights, the first reinforcement portion 1752 and the second reinforcement portion 1753 can withstand impacts in different directions, making the optical element driving mechanism 100 more stable.

[0251] At least a part of the first reinforcement portion 1752 is buried in the base 112. Specifically, the base 112 covers the first reinforcement portion 1752, and the first reinforcement portion 1752 does not protrude from the base 112. At least a part of the second reinforcement portion 1753 is buried in the base 112. Specifically, the base 112 covers the second reinforcement portion 1753, and the second reinforcement portion 1753 does not protrude from the base 112.

[0252] Please return to Figure 8 , the reinforcement body 1751 includes a first reinforcement body surface 1751a and a second reinforcement body surface 1751b.

[0253] The first reinforcement body surface 1751a is exposed on the base 112, and the second reinforcement body surface 1751b is exposed on the base 112. The first reinforcement body surface 1751a and the second reinforcement body surface 1751b face opposite directions, and the first reinforcement body surface 1751a and the second reinforcement body surface 1751b are arranged along the thickness direction (first direction D1) of the reinforcement body 1751.

[0254] In this way, the heat dissipation efficiency can be increased, making the optical element driving mechanism 100 more stable.

[0255] Generally speaking, the first driving component 130, the second driving component 145, the first supporting component 150, the second supporting component 155, the third supporting component 160, and the stabilizing component 170 of the optical element driving mechanism 100 of the present disclosure are arranged at a distance from the optical axis OA (that is, off-centered), so that the optical element driving mechanism 100 can accommodate the first movable part 120 without increasing the height (the first direction D1). Moreover, the present disclosure also has the effects of increasing stability and miniaturization.
