[0003] In view of this, the purpose of the present invention is to provide an optical element driving mechanism to solve the above-mentioned problem.

[0004] The utility model provides an optical element driving mechanism, comprising a fixed assembly, a first movable portion, and a driving assembly. The first movable portion is configured to be connected to a first optical element and to be movable relative to the fixed assembly. The driving assembly is configured to drive the first movable portion to move relative to the fixed assembly.

[0005] According to some embodiments of the present invention, the optical element driving mechanism further includes a second movable portion configured to connect to a second optical element, and the second movable portion is movable relative to the first movable portion. When a driving signal is input to the driving component, the driving component generates a first driving force to the first movable portion, and the driving component simultaneously generates a second driving force to the second movable portion. The fixing component includes an outer frame and a base. The outer frame is fixedly connected to the base. The outer frame has a first opening and a second opening. The first opening and the second opening are arranged along a first axial direction. The first optical element has a first base and a first shielding portion. The first base extends along the first axial direction. The first shielding portion extends from the first base along a second axial direction. The first shielding portion extends from the first base along a first extension direction. The second optical element has a second base and a second shielding portion. The second base extends along the first axial direction. The second shielding portion extends from the second base along the second axial direction. The second shielding portion extends from the second base along a second extension direction. The second extension direction is opposite to the first extension direction. The first movable portion is configured to move along the first axial direction so that the first shielding portion can selectively shield the first opening. The second movable portion is configured to move along the first axial direction so that the second shielding portion can selectively shield the second opening.

[0006] According to some embodiments of the present invention, the optical element driving mechanism further includes a positioning assembly configured to position the first movable part at a first position or a second position.

The second coil corresponds to the second magnetic element. The second magnetic element has a clamp-shaped structure. The second coil surrounds the second magnetic element. The first positioning element is made of a magnetic material. When the second coil is energized, the first positioning element and the second coil are inductively coupled and driven to rotate about a rotation axis relative to the second magnetic element and the base. The rotation axis is parallel to the second axial direction.

[0008] According to some embodiments of the present invention, the first positioning element has a first middle portion, a first positioning portion, a second positioning portion and a third positioning portion. The first positioning portion is arranged on one side of the first middle portion. The second positioning portion and the third positioning portion are arranged on the other side of the first middle portion.

The second positioning portion and the third positioning portion have an arc structure, configured to selectively stop the second movable portion. The base has two arc grooves, and the second positioning portion and the third positioning portion pass through the two arc grooves respectively. The base also has a first positioning shaft, which is inserted into the first middle portion. The first positioning shaft is located between the second positioning portion and the third positioning portion.

[0009] According to some embodiments of the present invention, the magnetic poles of the first magnetic element and the second magnetic element are arranged in the same direction. When the first coil is not energized, the first movable portion is located in the second position or the first position, and the second movable portion is located in the third position or the fourth position. The first movable portion has a first stop portion and a second stop portion. When the first movable portion is in the second position, the first positioning portion abuts against the second stop portion. The second movable portion has a third stop portion and a fourth stop portion. When the second movable portion is in the third position, the second positioning portion abuts against the third stop portion.

[0010] According to some embodiments of the present invention, when the first coil is energized, the first magnetic element is configured to induce the first coil to drive the first movable portion to move from the second position to the first position, and the second magnetic element is configured to induce the first coil to drive the second movable portion to move from the third position to the fourth position. When the first movable portion is in the first position, the first positioning portion abuts the first stop portion. When the second movable portion is in the fourth position, the third positioning portion abuts the fourth stop portion. When viewed along the second axial direction, a portion of the first movable portion does not overlap with the second movable portion.

[0011] According to some embodiments of the present invention, the magnetic poles of the first magnetic element and the second magnetic element are arranged in opposite directions. When the first coil is not energized, the first movable portion is located in the first position or the second position, and the second movable portion is located in the third position or the fourth position. The first movable portion has a first stop portion and a second stop portion. When the first movable portion is in the first position, the first positioning portion abuts against the first stop portion. The second movable portion has a third stop portion and a fourth stop portion. When the second movable portion is in the third position, the second positioning portion abuts against the third stop portion.

[0012] According to some embodiments of the present invention, when the first coil is energized, the first magnetic element is configured to induce the first coil to drive the first movable portion from the first position to the second position, and the second magnetic element is configured to induce the first coil to drive the second movable portion from the third position to the fourth position. When the first movable portion is in the second position, the first positioning portion abuts the second stop portion. When the second movable portion is in the fourth position, the third positioning portion abuts the fourth stop portion. When viewed along the second axial direction, the first movable portion overlaps the second movable portion.

[0013] According to some embodiments of the present invention, the outer frame further has a third opening, and the second opening is located between the first opening and the third opening. The second optical element further has a third shielding portion. The third shielding portion extends from the second base along the second axial direction. The third shielding portion of the second optical element can selectively shield the third opening. When the positioning assembly positions the second movable part in the third position, the third shielding portion does not shield the third opening. When the positioning assembly positions the second movable part in the fourth position, the third shielding portion shields the third opening. The second optical element further has a fourth shielding portion. The fourth shielding portion extends from the second base along the second axial direction. When viewed along the third axial direction, the second shielding portion is located between the third shielding portion and the fourth shielding portion. When the first movable part is in the second position and the second movable part is in the fourth position, the fourth shielding portion overlaps with the first shielding portion and the first opening. When viewed along the first axial direction, the fourth shielding portion does not overlap with the first shielding portion.

[0014] The utility model provides an optical element driving mechanism, comprising a fixed assembly, a first movable portion, a second movable portion, and a driving assembly. The driving assembly is configured to drive the first movable portion and the second movable portion to move relative to the fixed assembly, so that the first movable portion drives the first optical element to move to selectively cover the first opening of the fixed assembly, and the second movable portion drives the second optical element to move to selectively cover the second opening and the third opening of the fixed assembly.

[0015] In some embodiments, the first movable portion and the second movable portion may move in opposite directions, thereby enabling a portion of the first to third openings to be shielded while another portion is uncovered. In other embodiments, the first movable portion and the second movable portion may move in the same direction, thereby enabling the first to third openings to be shielded or opened simultaneously.

[0016] Based on the above configuration, the optical element drive mechanism can be used in a variety of scenarios. Furthermore, because the first and second movable parts share the same drive assembly, the overall volume of the optical element drive mechanism can be reduced, achieving miniaturization. Furthermore, because the multiple shielding portions are distributed across the two movable parts, the weight of a single movable part is reduced, resulting in more stable movement of both movable parts.

[0096] Please refer to Figures 1 to 3 , Figure 1 FIG. 1 is a perspective view of an optical element driving mechanism 100 according to an embodiment of the present invention. Figure 2 is an exploded view of an optical element driving mechanism 100 according to an embodiment of the present invention, and Figure 3 The optical element driving mechanism 100 according to an embodiment of the present invention is Figure 1 Cross-sectional view taken along line segment AA. The optical element driving mechanism 100 can be an optical camera module configured to carry and drive at least one optical element. The optical element driving mechanism 100 can be installed in various electronic devices or portable electronic devices, such as smartphones or laptops, to allow users to perform image capture functions.

[0097] In this embodiment, the optical element driving mechanism 100 may include a fixed component FA, a movable component MA, and a driving component DA. The movable component MA is movably connected to the fixed component FA. The driving component DA is configured to drive the movable component MA to move relative to the fixed component FA.

[0098] In this embodiment, if Figure 2 As shown, the fixed assembly FA includes an outer frame 102 and a base 112, while the movable assembly MA may include a first movable portion 108 and a second movable portion 109. The first movable portion 108 is configured to be connected to a first optical element 106 and is movable relative to the fixed assembly FA. Similarly, the second movable portion 109 is configured to be connected to a second optical element 110 and is movable relative to the first movable portion 108.

[0099] The driving assembly DA is configured to drive the first movable portion 108 and the second optical element 110 to move relative to the fixed assembly FA. In this embodiment, the first optical element 106 and the second optical element 110 can function as a light shield or a shutter, but are not limited thereto. In other embodiments, the first optical element 106 and the second optical element 110 can also function as a filter or an aperture.

[0100] In this embodiment, the first optical element 106 is detachably connected to the first movable portion 108, and the second optical element 110 is detachably connected to the second movable portion 109, but the present invention is not limited thereto. For example, in other embodiments, the first optical element 106 and the second optical element 110 can be fixedly connected to the first movable portion 108 and the second movable portion 109, respectively, using insert molding.

[0101] For example, the first movable portion 108 and the second movable portion 109 may be made of a non-metal material, such as plastic, and the first optical element 106 and the second optical element 110 may be made of a metal material, but is not limited thereto.

[0102] Furthermore, the outer frame 102 is fixedly connected to the base 112. The outer frame 102 can be combined with the base 112 to jointly accommodate the movable assembly MA and the driving assembly DA. Figure 2 As shown, the outer frame 102 has a first opening HP1, a second opening HP2, and a third opening HP3. The first opening HP1, the second opening HP2, and the third opening HP3 are arranged along a first axial direction AX1, and the second opening HP2 is located between the first opening HP1 and the third opening HP3. Figure 1 The outer frame 102 in FIG. 1 and some elements in subsequent figures are indicated by dotted lines, but this does not mean that the elements do not exist.

[0103] The base 112 accommodates a first optical module 150, a second optical module 155, and a third optical module 160. The first optical module 150 is, for example, a camera module, the second optical module 155 is, for example, an infrared sensor module, and the third optical module 160 is, for example, an infrared light source module, but is not limited thereto.

[0104] For example, the first optical module 150 may receive external light through the first opening HP1 to generate a digital image signal, the second optical module 155 may sense infrared light through the second opening HP2, and the third optical module 160 may emit infrared light through the third opening HP3.

[0105] like Figure 2 and Figure 3As shown, the first optical element 106 has a first base portion 1060 and a first shielding portion 1061. The first base portion 1060 extends along a first axial direction AX1, and the first shielding portion 1061 extends from the first base portion 1060 along a second axial direction AX2. Specifically, the first shielding portion 1061 extends from the first base portion 1060 along a first extension direction ED1.

[0106] Similarly, the second optical element 110 has a second base portion 1100, a second shielding portion 1101, and a third shielding portion 1103. The second base portion 1100 extends along the first axis AX1, the second shielding portion 1101 extends from the second base portion 1100 along the second axis AX2, and the third shielding portion 1103 also extends from the second base portion 1100 along the second axis AX2.

[0107] Specifically, the second blocking portion 1101 and the third blocking portion 1103 extend from the second base portion 1100 along a second extending direction ED2 , and the second extending direction ED2 is opposite to the first extending direction ED1 .

[0108] The first movable portion 108 is configured to move along the first axial direction AX1 so that the first blocking portion 1061 can selectively block the first opening HP1. Similarly, the second movable portion 109 is configured to move along the first axial direction AX1 so that the second blocking portion 1101 can selectively block the second opening HP2, and the third blocking portion 1103 can selectively block the third opening HP3.

[0109] In this embodiment, the optical element driving mechanism 100 further includes a positioning assembly PA configured to position the first movable portion 108 and the second movable portion 109. Figure 3 As shown, the positioning assembly PA and the driving assembly DA are arranged along the first axial direction AX1.

[0110] Furthermore, if Figure 3 As shown, when viewed along a third axis AX3 (Z axis), the first movable portion 108 and the second movable portion 109 are located on opposite sides of the driving assembly DA. The third axis AX3, the first axis AX1 and the second axis AX2 are perpendicular to each other.

[0111] In this embodiment, the driving assembly DA may include a first coil CL1, a first magnetic conductive element CM1, a first magnetic element ME1, and a second magnetic element ME2. The first magnetic element ME1 corresponds to the first coil CL1 and is disposed on the first movable portion 108, and the second magnetic element ME2 corresponds to the first coil CL1 and is disposed on the second movable portion 109.

[0112] The first magnetic conductive element CM1 is disposed on the base 112 and corresponds to the first coil CL1 . The first magnetic conductive element CM1 has a magnetic conductive material and a long strip structure, and the first coil CL1 surrounds the first magnetic conductive element CM1 .

[0113] When a driving signal is input to the driving element DA, the driving element DA generates a first driving force to the first movable portion 108 and simultaneously generates a second driving force to the second movable portion 109. The first driving force and the second driving force are, for example, electromagnetic driving forces, but are not limited thereto.

[0114] Specifically, when the first coil CL1 is energized, it will induce the first magnetic element ME1 and the second magnetic element ME2 to generate the aforementioned first driving force and second driving force, respectively driving the first movable portion 108 and the second movable portion 109 to move back and forth along the first axial direction AX1.

[0115] Furthermore, the positioning assembly PA may include a first positioning element 120, a second coil CL2, and a second magnetically conductive element CM2. The first positioning element 120 is movably disposed on the base 112, and the second coil CL2 corresponds to the second magnetically conductive element CM2. For example, in this embodiment, the second magnetically conductive element CM2 has a clamp-shaped structure, and the second coil CL2 surrounds one side of the second magnetically conductive element CM2.

[0116] Furthermore, the first positioning element 120 is made of a magnetically conductive material. Therefore, when the second coil CL2 is energized, the first positioning element 120 and the second coil CL2 are induced and driven to rotate around a rotation axis RX relative to the second magnetically conductive element CM2 and the base 112. The rotation axis RX is parallel to the second axial direction AX2. Figure 2 As shown, the positioning assembly PA may further include a blocking element 125 configured to block the first positioning element 120 to prevent the first positioning element 120 from being separated from the base 112 during the rotation process.

[0117] Please refer to Figures 2 to 4 . Figure 4 The optical element driving mechanism 100 according to an embodiment of the present invention is Figure 1 The three-dimensional cross-section of the midline segment BB. Figure 3 and Figure 4 As shown, the first positioning element 120 may have a first middle portion 121 , a first positioning portion 122 , a second positioning portion 123 and a third positioning portion 124 .

[0118] The first positioning portion 122 is disposed on one side of the first middle portion 121, and the second positioning portion 123 and the third positioning portion 124 are disposed on the other side of the first middle portion 121. The first positioning portion 122 may have an elongated structure configured to selectively stop the first movable portion 108, and the second positioning portion 123 and the third positioning portion 124 may have an arc-shaped structure configured to selectively stop the second movable portion 109.

[0119] like Figure 4 As shown, the base 112 has two arcuate grooves 112G, and the second positioning portion 123 and the third positioning portion 124 pass through the two arcuate grooves 112G respectively. The size of the arcuate groove 112G is larger than the size of each of the second positioning portion 123 and the third positioning portion 124, so that the second positioning portion 123 and the third positioning portion 124 can move along the two arcuate grooves 112G respectively. Figure 3 As shown, the base 112 may further have a first positioning shaft 112X inserted into the first middle portion 121 , and the first positioning shaft 112X is located between the second positioning portion 123 and the third positioning portion 124 .

[0120] Please refer to Figure 3 as well as Figures 5 to 8 . Figure 5 FIG. 1 is a perspective view showing that the first positioning element 120 positions the first movable portion 108 at a second position P2 and the second movable portion 109 at a third position P3 according to an embodiment of the present invention. Figure 6 is a perspective view of the first positioning element 120 in a release position according to an embodiment of the present invention, and Figure 7 is a perspective view showing that the first positioning element 120 positions the first movable portion 108 at a first position P1 and the second movable portion 109 at a fourth position P4 according to an embodiment of the present invention, and Figure 8 FIG. 1 is a top view of the first movable portion 108 located at the second position P2 and the second movable portion 109 located at the third position P3 according to an embodiment of the present invention.

[0121] like Figure 3 As shown, the magnetic poles of the first magnetic element ME1 and the second magnetic element ME2 are arranged in the same direction. That is, the arrangement order of a first N pole NP1 and a first S pole SP1 of the first magnetic element ME1 is the same as the arrangement order of a second N pole NP2 and a second S pole SP2 of the second magnetic element ME2.

[0122] For example, the first N pole NP1 and the first S pole SP1 are arranged along the X axis. Based on this configuration, when the first coil CL1 is energized, the first driving force and the second driving force generated are in opposite directions, so that the movement directions of the first movable portion 108 and the second movable portion 109 are also opposite.

[0123] Furthermore, in this embodiment, if Figure 5 and Figure 8 As shown, when the first coil CL1 and the second coil CL2 are not energized, the first movable portion 108 is located at the second position P2, and the second movable portion 109 is located at the third position P3. At this time, the first positioning element 120 is located at a locked position.

[0124] like Figure 5 As shown, the first movable portion 108 has a first stop portion 1081 and a second stop portion 1083. When the first movable portion 108 is located at the second position P2, the first positioning portion 122 abuts against the second stop portion 1083. The second stop portion 1083 is, for example (but not limited to) a sloped structure, configured to abut against the first positioning portion 122.

[0125] Similarly, the second movable portion 109 has a third stop portion 1091 and a fourth stop portion 1093. When the second movable portion 109 is at the third position P3, the second positioning portion 123 abuts against the third stop portion 1091. The third stop portion 1091 is, for example, a sloped structure, but is not limited thereto. Furthermore, the sloped structure of the third stop portion 1091 can be parallel to the sloped structure of the first stop portion 1081, but is not limited thereto.

[0126] like Figure 8 As shown, when the first positioning element 120 of the positioning assembly PA positions the first movable portion 108 at the second position P2, the first blocking portion 1061 blocks the first opening HP1. Similarly, when the first positioning element 120 of the positioning assembly PA positions the second movable portion 109 at the third position P3, the second blocking portion 1101 does not block the second opening HP2, and the third blocking portion 1103 does not block the third opening HP3.

[0127] Then, when the second coil CL2 is energized, the first positioning element 120 is driven by Figure 5 Rotate to the locked position Figure 6 At this time, the first movable portion 108 and the second movable portion 109 are no longer locked by the first positioning element 120.

[0128] Then, when the first coil CL1 is energized, the first magnetic element ME1 will induce the first coil CL1 to drive the first movable portion 108 to move Figure 6 The second position P2 moves to Figure 7 The first position P1 of the second magnetic element ME2 is electrically connected to the first coil CL1 to induce the second movable part 109 to move from Figure 6 The third position P3 moves to Figure 7 The fourth position P4.

[0129] Then, the second coil CL2 is energized again, so that the first positioning element 120 is driven by Figure 6 Rotate to the release position Figure 7 locked position. Figure 7 As shown, when the first movable portion 108 is located at the first position P1, the first positioning portion 122 abuts against the first stopping portion 1081. The first stopping portion 1081 is, for example (but not limited to) a slope structure, configured to abut against the first positioning portion 122.

[0130] Similarly, when the second movable portion 109 is at the fourth position P4, the third positioning portion 124 abuts against the fourth stop portion 1093. The fourth stop portion 1093 may be, for example, a sloped structure, but is not limited thereto. Furthermore, the sloped structure of the fourth stop portion 1093 may be parallel to the sloped structure of the first stop portion 1081, but is not limited thereto. At this point, the first coil CL1 can be de-energized, causing the first movable portion 108 to be positioned at the first position P1 and the second movable portion 109 to be positioned at the fourth position P4.

[0131] Furthermore, please refer to Figure 9 . Figure 9 FIG1 is a top view of the first movable portion 108 at the first position P1 and the second movable portion 109 at the fourth position P4 according to an embodiment of the present invention. When the first positioning element 120 of the positioning assembly PA positions the first movable portion 108 at the first position P1, the first blocking portion 1061 does not block the first opening HP1.

[0132] At the same time, when the first positioning element 120 of the positioning assembly PA positions the second movable portion 109 at the fourth position P4, the second blocking portion 1101 blocks the second opening HP2, and the third blocking portion 1103 blocks the third opening HP3. Figure 8 usage scenarios.

[0133] In addition, if the first movable portion 108 is to be returned to the second position P2 and the second movable portion 109 is to be returned to the third position P3, the first coil CL1 and the second coil CL2 can be energized again to drive the first movable portion 108, the second movable portion 109 and the first positioning element 120 to move. Figures 5 to 7 The driving method is similar, so I will not go into details here.

[0134] Furthermore, it is worth noting that if Figure 8 and Figure 9 As shown, since the first movable portion 108 and the second movable portion 109 move in opposite directions, a portion of the first movable portion 108 does not overlap with the second movable portion 109 when viewed along the second axial direction AX2 (X axis).

[0135] Based on the structural configuration of this embodiment, the optical element driving mechanism 100 can be used in various scenarios. For example, the first opening HP1 can be opened alone to enable the first optical module 150 to capture images. Alternatively, the first opening HP1 can be blocked while the second opening HP2 and the third opening HP3 are opened, allowing the second optical module 155 and the third optical module 160 to perform infrared sensing functions.

[0136] Please refer to Figures 10 and 11 . Figure 10 is a top view of the first movable portion 108 located at the first position P1 and the second movable portion 109 located at the third position P3 according to an embodiment of the present invention, and Figure 11 FIG. 1 is a top view of the first movable portion 108 located at the second position P2 and the second movable portion 109 located at the fourth position P4 according to an embodiment of the present invention.

[0137] In this embodiment, the magnetic poles of the first magnetic element ME1 and the second magnetic element ME2 are arranged in opposite directions. Figure 10 As shown, the arrangement order of the first N pole NP1 and the first S pole SP1 of the first magnetic element ME1 is opposite to the arrangement order of the second N pole NP2 and the second S pole SP2 of the second magnetic element ME2. Based on this configuration, the movement direction of the first movable portion 108 and the second movable portion 109 are the same.

[0138] For example, if Figure 10 As shown, when the first coil CL1 is not energized, the first movable portion 108 is located at the first position P1 , and the second movable portion 109 is located at the third position P3 .

[0139] When the first movable portion 108 is located at the first position P1, the first positioning portion 122 abuts against the first stop portion 1081 (eg, Figure 7 ), and when the second movable portion 109 is located at the third position P3, the second positioning portion 123 is in contact with the third stop portion 1091 (eg Figure 5 ).

[0140] Then, when the first coil CL1 is energized, the first magnetic element ME1 will induce the first coil CL1 to drive the first movable portion 108 to move Figure 10 The first position P1 moves to Figure 11The second magnetic element ME2 is energized and induced by the first coil CL1 to drive the second movable part 109 to move from Figure 10 The third position P3 moves to Figure 11 The fourth position P4.

[0141] When the first movable portion 108 is located at the second position P2, the first positioning portion 122 abuts against the second stop portion 1083 (eg, Figure 5 ), and when the second movable portion 109 is located at the fourth position P4, the third positioning portion 124 abuts against the fourth stop portion 1093 (such as Figure 7 At this time, the first coil CL1 may stop being energized, so that the first movable portion 108 is positioned at the second position P2, and the second movable portion 109 is positioned at the fourth position P4.

[0142] Similarly, if the first movable portion 108 is to be returned to the first position P1 and the second movable portion 109 is to be returned to the third position P3, the first coil CL1 and the second coil CL2 can be energized again to drive the first movable portion 108, the second movable portion 109, and the first positioning element 120 to move. The driving method is similar to the aforementioned driving method and will not be described in detail here.

[0143] Furthermore, it is worth noting that since the first movable portion 108 and the second movable portion 109 move in the same direction, Figure 10 and Figure 11 As shown, during the movement of the first movable portion 108 and the second movable portion 109 , when viewed along the second axis AX2 , the first movable portion 108 overlaps the second movable portion 109 .

[0144] Please refer to Figures 12 to 14 . Figure 12 FIG2 is a top view of the first movable portion 108 located at the first position P1 and the second movable portion 109 located at the third position P3 according to an embodiment of the present invention. Figure 13 is a top view of the first movable portion 108 located at the second position P2 and the second movable portion 109 located at the fourth position P4 according to an embodiment of the present invention, and Figure 14 The optical element driving mechanism 100 according to an embodiment of the present invention is Figure 13 Cross-sectional view of line segment CC.

[0145] In this embodiment, if Figure 12 As shown, the second optical element 110 may further have a fourth blocking portion 1104 , and the fourth blocking portion 1104 extends from the second base portion 1100 along the second axial direction AX2 .

[0146] like Figure 12As shown, when viewed along the third axial direction AX3 (Z axis), the second shielding portion 1101 is located between the third shielding portion 1103 and the fourth shielding portion 1104. When the first movable portion 108 is at the first position P1 and the second movable portion 109 is at the third position P3, the fourth shielding portion 1104 does not block the first opening HP1.

[0147] When the first movable part 108 is Figure 12 The first position P1 in the Figure 13 The second position P2 in the middle, and the second movable part 109 is Figure 12 The third position P3 in the Figure 13 When the fourth blocking portion 1104 is at the fourth position P4, the fourth blocking portion 1104 overlaps the first blocking portion 1061 and the first opening HP1. In other words, the fourth blocking portion 1104 and the first blocking portion 1061 will block the first opening HP1 together.

[0148] For example, in this embodiment, the fourth shielding portion 1104 is a filter that can filter blue light, and the first shielding portion 1061 is a filter that can filter green light, so that the first optical module 150 can receive pure red light. The application of the fourth shielding portion 1104 and the first shielding portion 1061 is not limited to this embodiment.

[0149] In addition, it is worth noting that Figure 14 As shown, when viewed along the first axial direction AX1 (Y axis), the fourth blocking portion 1104 does not overlap the first blocking portion 1061. Based on this configuration, it is possible to ensure that the first optical element 106 does not collide with the second optical element 110, thereby preventing the smooth movement of the first movable portion 108 and the second movable portion 109.

[0150] The present invention provides an optical element driving mechanism 100, comprising a fixed assembly FA, ​​a first movable portion 108, a second movable portion 109, and a driving assembly DA. The driving assembly DA is configured to drive the first movable portion 108 and the second movable portion 109 to move relative to the fixed assembly FA, ​​such that the first movable portion 108 drives the first optical element 106 to move to selectively cover the first opening HP1 of the fixed assembly FA, ​​and the second movable portion 109 drives the second optical element 110 to move to selectively cover the second opening HP2 and the third opening HP3 of the fixed assembly FA.

[0151] In some embodiments, the first movable portion 108 and the second movable portion 109 may move in opposite directions, thereby partially shielding the first to third openings HP1 to HP3 and uncovering the other portions. In other embodiments, the first movable portion 108 and the second movable portion 109 may move in the same direction, thereby simultaneously shielding or uncovering the first to third openings HP1 to HP3.

[0152] Based on the above configuration, the optical element driving mechanism 100 can be used in a variety of scenarios. Furthermore, because the first movable portion 108 and the second movable portion 109 share the same driving assembly, the overall volume of the optical element driving mechanism 100 can be reduced, achieving miniaturization. Furthermore, because the multiple shielding portions are distributed across the two movable portions, the weight of each movable portion is reduced, resulting in more stable movement of both movable portions.
