Description

Technical Field

[0001] The present disclosure relates to an optical element driving mechanism, and more particularly, to an optical element driving mechanism for an electronic device. Background Art

[0002] With the development of technology, many electronic devices (such as computers or tablets) now have the function of taking photos or recording videos. However, when an optical element with a long focal length (such as a lens) is required to be installed in the above-mentioned electronic device, the thickness of the electronic device will increase, which is not conducive to the thinness and stability of the electronic device. In view of this, how to design an optical element driving mechanism and an optical device that can make the electronic device thinner and more stable has become an important issue. Summary of the invention

[0003] An object of the present invention is to provide an optical element driving mechanism to solve at least one of the problems.

[0004] In order to solve the above-mentioned known problems, the present disclosure provides an optical element driving mechanism, including a first movable part, a fixed part and a first driving assembly. The first movable part is connected to a first optical element. The first movable part can move relative to the fixed part. The first driving assembly drives the first movable part to move.

[0005] In one embodiment of the present disclosure, when viewed along a first direction perpendicular to an optical axis, the fixed portion having a polygonal structure further includes a first side and a second side. The first side extends along the optical axis. The second side extends along the optical axis. When viewed along the first direction, the first side and the second side are respectively located on both sides of the optical axis. When a first driving current is input to the first driving component, the first driving component generates a first driving force on a first force-bearing portion of the first movable portion. When viewed along the first direction, the first force-bearing portion is located between the first side and the optical axis.

[0006] The beneficial effect of the present invention is that the first driving assembly, the second driving assembly, the first supporting assembly, the second supporting assembly, the third supporting assembly, and the stabilizing assembly of the optical element driving mechanism of the present invention are arranged at a distance from the optical axis (that is, off-center), so that the optical element driving mechanism does not need to increase the height (in the first direction) to accommodate the first movable part. In addition, the present invention also has the effect of increasing stability and miniaturization. BRIEF DESCRIPTION OF THE DRAWINGS

[0121] First see Figure 1 , Figure 1 is a schematic diagram of an electronic device 1 according to some embodiments of the present disclosure. Figure 1 As shown, an optical element driving mechanism 100 of some embodiments of the present disclosure may be installed in an electronic device 1 for taking photos or photographs, wherein the electronic device 1 may 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 position and size relationship between the optical element driving mechanism 100 and the electronic device 1 shown in the figure is only an example, and does not limit the position and size relationship between the optical element driving mechanism 100 and the electronic device 1. In fact, the optical element driving mechanism 100 can be installed at different positions in the electronic device 1 according to different requirements.

[0122] See also Figure 2 and Figure 3 . Figure 2 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, wherein an outer frame 111 is represented by a dotted line. Figure 3 is an exploded 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.

[0123] 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 supporting component 150, a second supporting component 155, a third supporting component 160, a stabilizing component 170, a reinforcing component 175, a circuit component 180, and a connecting component 190.

[0124] The fixing part 110 may include an outer frame 111, a base 112 and a fixing 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 inner space to accommodate other elements of the optical element driving mechanism 100 or the first optical element OE1 and the second optical element OE2.

[0125] like Figure 2 As shown, a light L can be incident on the second optical element OE2 along a first direction D1 from outside the optical element driving mechanism 100. The second optical element OE2 refracts and / or reflects the light L from the first direction D1 to be incident on the first optical element OE1 along the optical axis OA (or a third direction D3 perpendicular to the first direction D1).

[0126] The first movable portion 120 may be connected to the first optical element OE1, and the first movable portion 120 may move relative to the fixed portion 110. For example, the first movable portion 120 may move relative to the fixed portion 110 along the optical axis OA, and the first optical element OE1 may move relative to the fixed portion 110 along the optical axis OA with the first movable portion 120.

[0127] The first driving component 130 can drive the first movable part 120 to move relative to the fixed part 110. The first driving component 130 can include a first driving magnet 131, a first driving coil 132, a first magnetic shielding element 133, a second driving magnet 134, a second driving coil 135 and a second magnetic shielding element 136.

[0128] The first driving magnet 131 and the second driving magnet 134 can be arranged on the first movable part 120, and the first driving coil 132 and the second driving coil 135 can be arranged on the base 112, so 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.

[0129] The first magnetic shielding element 133 corresponds to the first driving magnet 131, and the second magnetic shielding element 136 corresponds to the second driving magnet 134. For example, the first magnetic shielding element 133 can be disposed adjacent to the first driving magnet 131 or attached to the first driving magnet 131, and the second magnetic shielding element 136 can be disposed adjacent to the second driving magnet 134 or attached to the second driving magnet 134.

[0130] The first magnetic shielding element 133 and the second magnetic shielding element 136 may have magnetic conductive materials to prevent magnetic leakage of the first driving magnet 131 and / or the second driving magnet 134 , thereby preventing unwanted magnetic effects on other elements of the optical element driving mechanism 100 or external devices.

[0131] The second movable portion 140 may be connected to the second optical element OE2, and the second movable portion 140 may move relative to the fixed portion 110. For example, the second movable portion 140 may rotate relative to the fixed portion 110 around a first direction D1 and / or a second direction D2 perpendicular to the optical axis OA, and the second optical element OE2 may rotate relative to the fixed portion 110 around the first direction D1 and / or the second direction D2.

[0132] The second driving component 145 drives the second movable portion 140 to move relative to the fixed portion 110. When the second driving component 145 receives current from the circuit component 180, the second driving component 145 drives the second movable portion 140 to rotate relative to the fixed portion 110 around the first direction D1 and / or the second direction D2.

[0133] The first supporting assembly 150 , the second supporting assembly 155 , and the third supporting assembly 160 may support the first movable portion 120 , so that the first movable portion 120 may move relative to the fixed portion 110 along the optical axis OA.

[0134] The stabilizing element 170 stabilizes the first movable portion 120 . The stabilizing element 170 includes a first stabilizing component 171 and a second stabilizing component 172 .

[0135] The reinforcement component 175 is made of metal and can be embedded in the base 112 to enhance the structure of the base 112 .

[0136] The circuit component 180 is directly or indirectly connected to an external circuit to supply current to other components of the optical element driving mechanism 100 , such as the first driving coil 132 and the second driving coil 135 of the first driving component 130 and the second driving component 145 .

[0137] See also Figure 4 , Figure 4 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 are arranged along Figure 2 A cross-sectional view along the A-A' line.

[0138] like Figure 4 As 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.

[0139] The first driving magnet 131, the first driving coil 132, and the first magnetic shielding element 133 are located between the optical axis OA and the first side 110a1. Furthermore, the distance between the first driving magnet 131, the first driving coil 132, and the first magnetic shielding element 133 and the first side 110a1 is smaller than the distance between the first driving magnet 131, the first driving coil 132, and the first magnetic shielding element 133 and the second side 110a2. In other words, the first driving magnet 131, the first driving coil 132, and the first magnetic shielding element 133 are arranged close to the first side 110a1 and away from the second side 110a2.

[0140] The second driving magnet 134, the second driving coil 135 and the second magnetic shielding element 136 are located between the optical axis OA and the second side 110a2. Furthermore, the distance between the second driving magnet 134, the second driving coil 135 and the second magnetic shielding element 136 and the second side 110a2 is smaller than the distance between the second driving magnet 134, the second driving coil 135 and the second magnetic shielding element 136 and the first side 110a1. In other words, the second driving magnet 134, the second driving coil 135 and the second magnetic shielding element 136 are arranged close to the second side 110a2 and away from the first side 110a1.

[0141] When a first driving current from the circuit component 180 is input to the first driving coil 132 of the first driving component 130 , the first driving component 130 generates a first driving force (indicated by an arrow) F1 and applies force to a first force-bearing portion 120 ′ of the first movable portion 120 .

[0142] When observed along the first direction D1, the first force-bearing portion 120' is located between the first side 110a1 of the fixed portion 110 and the optical axis OA. It can be imagined that when observed along the first direction D1, the first force-bearing 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-bearing portion 120' and the first side 110a1 is smaller than the distance between the first force-bearing portion 120' and the second side 110a2. In other words, the first force-bearing portion 120' is close to the first side 110a1 and away from the second side 110a2.

[0143] When the 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 force to a second force-bearing portion 120 ″ of the first movable portion 120 .

[0144] When observed along the first direction D1, the second force-bearing portion 120" is located between the second side 110a2 of the fixed portion 110 and the optical axis OA. It can be imagined that, when observed along the first direction D1, the second force-bearing portion 120" and the second driving magnet 134 overlap with 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-bearing portion 120" and the second side 110a2 is smaller than the distance between the second force-bearing portion 120" and the first side 110a1. That is, the second force-bearing portion 120" is close to the second side 110a2 and away from the first side 110a1.

[0145] According to some embodiments of the present disclosure, the magnetic strength of the first driving magnet 131 is different from the magnetic strength of the second driving magnet 134. In detail, according to some embodiments of the present disclosure, the magnetic strength of the first driving magnet 131 is greater than the magnetic strength of the second driving magnet 134.

[0146] According to some embodiments of the present disclosure, the strength of the first driving force F1 is different from the strength of the second driving force F2. According to some embodiments of the present disclosure, the strength of the first driving force F1 is greater than the strength of the second driving force F2.

[0167] The first magnetic isolation portion 1361 of the second magnetic isolation element is between the second driving magnet 134 and the second driving assembly 145 .

[0168] When viewed along the optical axis OA, the first magnetic shielding portion 1361 of the second magnetic shielding element at least partially overlaps with the second driving magnet 134 .

[0169] When viewed along the optical axis OA, the second magnetic shielding portion 1362 of the second magnetic shielding element does not overlap with the second driving magnet 134 .

[0171] When viewed along a direction perpendicular to the first surface 1341 of the second driving magnet (the second direction D2 ), the first magnetic shielding portion 1361 of the second magnetic shielding element does not overlap with the second driving magnet 134 .

[0172] When viewed along a direction perpendicular to the first surface 1341 of the second driving magnet (the second direction D2 ), the second magnetic shielding portion 1362 of the second magnetic shielding element at least partially overlaps with the second driving magnet 134 .

[0173] See also Figure 5 , Figure 5 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 are arranged along Figure 2 Cross-sectional view along line BB'.

[0174] The first supporting assembly 150 includes a first intermediate element 151 and a first supporting 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 supporting portion 152 corresponds to the first intermediate element 151, and the first intermediate element 151 may move relative to the first supporting portion 152. For example, the first intermediate element 151 may move relative to the first supporting portion 152 along the optical axis OA.

[0175] 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.

[0176] When viewed along the first direction D1, the first support assembly 150 is located between the first side 110a1 of the fixing portion 110 and the optical axis OA. The distance between the first support assembly 150 and the first side 110a1 is smaller than the distance between the first support assembly 150 and the second side 110a2. In other words, the first support assembly 150 is close to the first side 110a1 and away from the second side 110a2.

[0177] See also Figure 6 , Figure 6 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 are arranged along Figure 2 Cross-sectional view along line C-C'.

[0178] The second supporting assembly 155 includes a second intermediate element 156 and a second supporting 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 supporting portion 157 corresponds to the second intermediate element 156, and the second intermediate element 156 may move relative to the second supporting portion 157. For example, the second intermediate element 156 may move relative to the second supporting portion 157 along the optical axis OA.

[0179] 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 different directions from the first support portion first surface 1521 and the first support portion second surface 1522.

[0180] The second supporting portion opening 1572 is adjacent to the second supporting portion surface 1571 , such that the second supporting portion surface 1571 is “broken” near the second side 110 a 2 of the fixing portion 110 .

[0181] This can help assemble the optical element driving mechanism 100 and make the optical element driving mechanism 100 more lightweight and compact.

[0182] When viewed along the first direction D1, the second support assembly 155 is located between the second side 110a2 of the fixing portion 110 and the optical axis OA. The distance between the second support assembly 155 and the first side 110a2 is smaller than the distance between the second support assembly 155 and the first side 110a1. In other words, the second support assembly 155 is close to the second side 110a2 and away from the first side 110a1.

[0183] See also Figure 7 , Figure 7The optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2 according to some embodiments of the present disclosure are arranged along Figure 2 Cross-sectional view along the D-D' line.

[0184] The third supporting assembly 160 includes a third intermediate element 161 and a third supporting 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 supporting portion 162 corresponds to the third intermediate element 161, and the third intermediate element 161 may move relative to the third supporting portion 162. For example, the third intermediate element 161 may move relative to the third supporting portion 162 along the optical axis OA.

[0185] The third support portion 162 may be located on the first movable portion 120. The third support portion 162 includes a third support portion first surface 1621 and a third support portion second surface 1622. The third support portion first surface 1621 and the third support portion second surface 1622 face different directions, and both the third support portion first surface 1621 and the third support portion second surface 1622 are in direct contact with the third intermediate element 161.

[0186] When viewed along the first direction D1, the third support assembly 160 is located between the first side 110a1 of the fixing portion 110 and the optical axis OA. The distance between the third support assembly 160 and the first side 110a1 is smaller than the distance between the third support assembly 160 and the second side 110a2. In other words, the third support assembly 160 is close to the first side 110a1 and away from the second side 110a2.

[0187] Please also see Figure 5 , Figure 6 and Figure 7 , the first support portion first surface 1521 and the third support portion first surface 1621 face the same direction; the first support portion first surface 1521 and the second support portion surface 1571 and the third support portion second surface 1622 face different directions.

[0188] The first support portion second surface 1522 and the third support portion second surface 1622 face the same direction; the first support portion second surface 1522 and the second support portion surface 1571 and the third support portion first surface 1621 face different directions.

[0189] The second support portion surface 1571 faces different directions from the third support portion first surface 1621 and the third support portion second surface 1622 .

[0190] As a result, 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 undesired direction (eg, the second direction D2 ).

[0191] Please continue reading Figure 5 , Figure 6 and Figure 7 Since the first support portion first surface 1521 and the first support portion second surface 1522 are both 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 second support portion surface 1571 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 the third support portion first surface 1621 and the third support portion second surface 1622 are both 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.

[0192] That is, 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.

[0193] 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 two.

[0194] 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 is helpful to assemble the optical element driving mechanism 100. In addition, the optical element driving mechanism 100 can be made more stable.

[0195] See also Figure 8 , Figure 8 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 are arranged along Figure 2 Cross-sectional view along line E-E'.

[0196] The first stabilizing element 171 and the second stabilizing element 172 of the stabilizing assembly 170 can be magnets. The first stabilizing element 171 and the second stabilizing element 172 are disposed adjacent to the fixed portion magnetic conductive element 113 having a magnetic conductive material, and are disposed on the first movable portion 120 .

[0197] Therefore, the first stabilizing element 171 generates a first stabilizing force SF1 (indicated by an arrow) on the first movable portion 120 to act on a first acting portion 170 ′, and the second stabilizing element 172 generates a second stabilizing force SF2 (indicated by an arrow) on the first movable portion 120 to act on a second acting portion 170 ″.

[0198] like Figure 8 As shown, when viewed along the first direction D1, the first stabilizing element 171 and the first acting portion 170' are located between the optical axis OA and the first side 110a1 of the fixing portion 110; and, when viewed along the first direction D1, the second stabilizing element 172 and the second acting portion 170" are located between the optical axis OA and the second side 110a2 of the fixing portion 110.

[0199] According to some embodiments of the present disclosure, the magnetic strength of the first stabilizing element 171 is different from the magnetic strength of the second stabilizing element 172. In detail, according to some embodiments of the present disclosure, the magnetic strength of the first stabilizing element 171 is greater than the magnetic strength of the second stabilizing element 172.

[0200] According to some embodiments of the present disclosure, the strength of the first stabilizing force SF1 is different from the strength of the second stabilizing force SF2. In detail, according to some embodiments of the present disclosure, the strength of the first stabilizing force SF1 is greater than the strength of the second stabilizing force SF2.

[0201] Since the magnetic strength of the second driving magnet 134 and the magnetic strength of the second stabilizing element 172 adjacent to the second side 110a2 are smaller than the magnetic strength of the first driving magnet 131 and the magnetic strength of the first stabilizing element 171 adjacent to the first side 110a1, the magnetic force effect on the second side 110a2 is smaller than the magnetic force effect on the first side 110a1. In this way, the external elements at the first side 110a1 can be prevented from being affected by the magnetic force of the second driving magnet 134 and the second stabilizing element 172, so that the external elements can be disposed at the first side 110a1.

[0202] See also Fig. 9 , Fig. 9 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 are arranged along Figure 2 Cross-sectional view along line F-F'.

[0203] like Fig. 9 As shown, when viewed along the first direction D1 , the distance between the first stabilizing element 171 and the second supporting assembly 155 is greater than the distance between the first stabilizing element 171 and the first supporting assembly 150 and the distance between the first stabilizing element 171 and the third supporting assembly 160 .

[0204] Furthermore, when viewed along the first direction D1 , the first supporting element 150 , the second supporting element 155 and the third supporting element 160 may form a triangle (indicated by a dotted line) TA, and the first stabilizing element 171 is disposed in the triangle TA.

[0205] As a result, the first stabilizing element 171 generates a first stabilizing force SF1 (see Figure 8 ) is also located in the triangle TA; therefore, the first supporting component 150, the second supporting component 155 and the third supporting component 160 can stably support the first stabilizing force SF1, so that the structure of the optical element driving mechanism 100 is more stable.

[0206] Please continue reading Fig. 9 When viewed along the first direction D1 , the distance between the second stabilizing element 172 and the second supporting assembly 155 is smaller than the distance between the second stabilizing element 172 and the first supporting assembly 150 and the distance between the second stabilizing element 172 and the third supporting assembly 160 .

[0207] Furthermore, the second stabilizing element 172 generates a second stabilizing force SF2 (see Figure 8 ) is small, so the second stabilizing element 172 may not be arranged in the triangle TA.

[0208] In this way, in addition to being able to balance the stabilizing force applied to the first movable portion 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.

[0209] See also Fig.10 , Fig.10 yes Figure 8 A modified embodiment of the optical element driving mechanism 100, the first optical element OE1 and the second optical element OE2.

[0210] exist Fig.10 In the embodiment, 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 portion 110 no longer has magnetic force, so that the second side 110a2 is not affected by the magnetic force.

[0211] exist Fig.10, the second driving force F2 is zero, and the second stabilizing force SF2 is also zero. The first movable portion 120 is driven only by the first driving force F1, and the first movable portion 120 is fixed only by the first stabilizing force SF1. In this way, the number of components of the optical element driving mechanism 100 can be reduced, thereby making the optical element driving mechanism 100 more lightweight and miniaturized. In addition, the external components at the first side 110a1 can be prevented from being affected by the magnetic force, thereby allowing the external components to be disposed at the first side 110a1.

[0212] See also Fig.11 , Fig.11 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.

[0213] When viewed along the first direction D1, the external device 200 can be disposed adjacent to the second side 110a2 without being disturbed by excessive magnetic force. According to some embodiments of the present disclosure, the external device 200 can include another optical module, an antenna, a vibration motor, and the like.

In addition, the first circuit component connecting portion 183 and the second circuit component connecting portion 184 have a plate-like structure.

[0216] The circuit assembly 180 is disposed on the base 112 of the fixing portion 110. The base 112 includes a first groove 1121, a second groove 1122 and a groove spacer 1123. In addition, the connecting assembly 190 includes a first connecting element 191, a second connecting element 192, a third connecting element 193, a fourth connecting element 194 and a fifth connecting element 195.

[0217] like Fig.12 and Fig.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. In detail, the first lead 181 is disposed in the first groove 1121 and the second lead 182 is disposed in the second groove 1122.

[0218] The first groove 1121 and the second groove 1122 are formed on the surface of the base 112 facing away from the first movable portion 120 (parallel to the second direction D2 or the −X axis) (ie, the first groove 1121 and the second groove 1122 are formed on the outward surface).

[0219] The base 112 is at least partially located between the first lead 181 and the first movable portion 120, and at least partially located between the second lead 182 and the first movable portion 120. In other words, it is emphasized that the first groove 1121 and the second groove 1122 do not penetrate the base 112 in the second direction D2.

[0220] 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 at the same time, so that the electrical circuit of the optical element driving mechanism 100 is more stable.

[0221] like Fig.12 and Fig.13 As 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 stable. 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. The first circuit component connection portion 183 is connected to the base 112 via the fourth connection element 194, and the second circuit component connection portion 184 is connected to the base 112 via the fifth connection element 195; in this way, the first circuit component connection portion 183 and the second circuit component connection portion 184 can be fixed to the base 112, and the first lead 181 and the second lead 182 can be protected from oxidation. According to some embodiments of the present disclosure, the first connecting element 191 , the second connecting element 192 , the third connecting element 193 , the fourth connecting element 194 and the fifth connecting element 195 may be conductive adhesive or solder to effectively electrically connect the elements to desired locations.

In detail, the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194 and the fifth connecting element 195 are set in the optical element driving mechanism 100 at different times.

[0224] According to some embodiments of the present disclosure, multiple of the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194, and the fifth connecting element 195 can be set simultaneously. In detail, multiple of the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194, and the fifth connecting element 195 can be set in the optical element driving mechanism 100 at the same time.

[0225] According to some embodiments of the present disclosure, all of the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194, and the fifth connecting element 195 can be set at the same time.

[0226] According to some embodiments of the present disclosure, the first connecting element 191 and the second connecting element 192 have an integrally formed structure (for example, the first connecting element 191 and the second connecting element 192 can contact each other or be combined into one). According to some embodiments of the present disclosure, a plurality of the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194 and the fifth connecting element 195 have an integrally formed structure. According to some embodiments of the present disclosure, all of the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194 and the fifth connecting element 195 have an integrally formed structure. An integrally formed connecting element can facilitate the assembly of the optical element driving mechanism 100 and can make the optical element driving mechanism 100 more stable. According to some embodiments of the present disclosure, the first connecting element 191, the second connecting element 192, the third connecting element 193, the fourth connecting element 194 and the fifth connecting element 195 can be insulating glue so that the integrally formed connecting element does not cause a short circuit.

[0227] See also Fig.14 , Fig.14 is a stereoscopic view of a reinforcement assembly 175 of an optical element driving mechanism 100 according to some embodiments of the present disclosure.

[0228] like Fig.14 As 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 .

[0229] The reinforcing body 1751, the first reinforcing part 1752 and the second reinforcing part 1753 have a plate-like structure. The first opening 1754 is formed between the reinforcing body 1751 and the first reinforcing part 1752. The second opening 1755 is formed between the reinforcing body 1751 and the second reinforcing part 1753. Parts (or materials) of the base 112 can be embedded in the first opening 1754 and the second opening 1755, so that the base 112 and the reinforcing assembly 175 are more firmly combined.

[0230] When viewed from a direction perpendicular to the first direction D1, the upper surface of the first reinforcing portion 1752 is parallel to the reinforcing body 1751. The upper surface of the second reinforcing portion 1753 is not parallel to the reinforcing body 1751. The first reinforcing portion 1752 is not parallel to the second reinforcing portion 1753.

[0231] like Fig.14As shown, in the direction of the thickness of the reinforcing body 1751 (the first direction D1), a center 1751C of the reinforcing body 1751 and a center 1752C of the first reinforcing portion 1752 have a distance greater than zero. In other words, the reinforcing body 1751 and the first reinforcing portion 1752 are at different heights. The first reinforcing portion 1752 is integrally formed with the reinforcing body 1751, and the first reinforcing portion 1752 is an arched structure protruding from the surface of the reinforcing body 1751 along the first direction D1.

[0232] In the direction of the thick part of the reinforcing body 1751 (the first direction D1), the center 1753C of the second reinforcing part 1753 and the center 1752 of the first reinforcing part 1752 have a distance greater than zero. In other words, the first reinforcing part 1752 and the second reinforcing part 1753 are at different heights. The second reinforcing part 1753 and the reinforcing body 1751 are integrally formed, and the second reinforcing part 1753 is an arched structure protruding from the surface of the reinforcing body 1751 in a direction greater than 0 degrees with the first direction D1. Since the first reinforcing part 1752 and the second reinforcing part 1753 are at different angles and heights, the first reinforcing part 1752 and the second reinforcing part 1753 can withstand impacts in different directions, so that the optical element driving mechanism 100 can be more stable.

[0233] The first reinforcing portion 1752 is at least partially buried in the base 112. Specifically, the base 112 covers the first reinforcing portion 1752, and the first reinforcing portion 1752 is not exposed from the base 112. The second reinforcing portion 1753 is at least partially buried in the base 112. Specifically, the base 112 covers the second reinforcing portion 1753, and the second reinforcing portion 1753 is not exposed from the base 112.

[0234] Please go back Figure 8 The reinforcement body 1751 includes a first reinforcement body surface 1751a and a second reinforcement body surface 1751b.

[0235] The first reinforcing body surface 1751a is exposed from the base 112, and the second reinforcing body surface 1751b is exposed from the base 112. The first reinforcing body surface 1751a and the second reinforcing body surface 1751b face opposite directions and are arranged along the thickness direction (first direction D1) of the reinforcing body 1751.

[0236] In this way, the heat dissipation efficiency can be increased, making the optical element driving mechanism 100 more stable.

[0237] In general, the first driving assembly 130, the second driving assembly 145, the first supporting assembly 150, the second supporting assembly 155, the third supporting assembly 160, and the stabilizing assembly 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-center), so that the optical element driving mechanism 100 does not need to increase the height (in the first direction D1) to accommodate the first movable portion 120. In addition, the present disclosure also has the effect of increasing stability and miniaturization.
