[0105] Please refer to Figures 1 to 3 , Figure 1 is a perspective view of an optical system 10 according to an embodiment of the present disclosure, Figure 2 is an exploded view of an optical system 10 according to an embodiment of the present disclosure, and Figure 3 The optical system 10 according to an embodiment of the present disclosure is Figure 1The optical system 10 is a cross-sectional view taken along line AA. The optical system 10 may be an optical camera module configured to carry and drive at least one optical element. The optical system 10 may be installed in various electronic devices or portable electronic devices, such as a smartphone, to allow the user to perform image capture functions.

[0106] In this embodiment, the optical system 10 may include a base 15, a first optical mechanism 100, a second optical mechanism 200, and a third optical mechanism 300. The base 15 may be, for example, but not limited to, a main circuit board of a portable electronic device. The first optical mechanism 100, the second optical mechanism 200, and the third optical mechanism 300 are mounted on the base 15. It should be noted that the dimensions of the base 15 are not limited to those illustrated in this disclosure.

[0107] The first optical mechanism 100 may include a fixing element FA, a first movable portion 108 and a first driving element DA1. Figure 2 As shown, the fixing assembly FA includes a cover 102 and a base 112, and the first movable portion 108 may include a first support base 1081 and a first optical element 1082. The first support base 1081 is configured to connect to and support the first optical element 1082. The first optical element 1082 can function as a light shield or a shutter, but is not limited thereto. In other embodiments, the first optical element 1082 may also function as a filter or an aperture.

[0108] The cover 102 is fixedly mounted on the base 112. The cover 102 and the base 112 can be combined to accommodate the first movable portion 108 and the first driving assembly DA1. The first movable portion 108 can move relative to the fixed assembly FA, ​​and the first driving assembly DA1 is configured to drive the first movable portion 108 to move relative to the fixed assembly FA.

[0109] The first optical mechanism 100 may further include a guide assembly GA configured to guide the first movable portion 108 to move relative to the fixed assembly FA. A friction force may be generated between the first movable portion 108 and the guide assembly GA, and the first movable portion 108 may be temporarily positioned at two relative positions on the fixed assembly FA by the friction force.

[0110] For example, the guide element GA may be a first groove 1121 configured to accommodate the first supporting base 1081 and the first magnetic element MG1 , and the friction force may be generated between the first supporting base 1081 and the first groove 1121 .

[0111] The base 112 of the fixing assembly FA may include a first opening OP1 and a second opening OP2. The first opening OP1 is configured to allow a first light ray LT1 to pass through and enter the second optical mechanism 200, and the second opening OP2 is configured to allow a second light ray LT2 to pass through and enter the third optical mechanism 300. The first light ray LT1 is parallel to the second light ray LT2, and the first light ray LT1 is, for example, parallel to the Z-axis.

[0112] In this embodiment, the second optical mechanism 200 may be a camera module configured to receive the first light LT1 to capture an image, and the third optical mechanism 300 may be a depth sensing module configured to receive the second light LT2 to sense a distance between an object and the optical system 10 .

[0113] Correspondingly, the cover 102 has a first light-transmitting portion 1021 and a second light-transmitting portion 1022, corresponding to the first opening OP1 and the second opening OP2, respectively. The first light-transmitting portion 1021 and the second light-transmitting portion 1022 can be through-holes, but are not limited thereto. In other embodiments, the first light-transmitting portion 1021 and the second light-transmitting portion 1022 can also be made of a light-transmitting plastic material.

[0114] Please refer to Figures 1 to 4 , Figure 4 FIG1 is a top view of a portion of an optical system 10 according to an embodiment of the present disclosure. When viewed along a first axis AX1 (the Z axis), a first opening OP1 and a second opening OP2 are aligned along a second axis AX2. The first axis AX1 is parallel to the first light ray LT1, and the second axis AX2 is perpendicular to the first axis AX1.

[0115] When viewed along the first axis AX1, the first drive assembly DA1 and the first opening OP1 are arranged along the second axis AX2. When viewed along the second axis AX2, the first opening OP1 overlaps at least a portion of the second opening OP2. That is, the first opening OP1 and the second opening OP2 may be on the same horizontal plane.

[0116] like Figure 4 As shown, when viewed along the first axis AX1, the fixed assembly FA has an elongated, strip-shaped structure extending along the second axis AX2. When viewed along the first axis AX1, a first opening OP1 is located at a first end EP1 of the fixed assembly FA. Similarly, when viewed along the first axis AX1, a second opening OP2 is located at a second end EP2 of the fixed assembly FA.

[0117] In this embodiment, the first driving assembly DA1 includes a coil CL, a first magnetic element MG1 and a magnetic conductive element CM. The first magnetic element MG1 corresponds to the coil CL, and the magnetic conductive element CM corresponds to the coil CL and has a magnetic conductive material.

[0118] Coil CL surrounds a magnetically permeable element CM, which has a plate-like structure and is perpendicular to a third axis AX3. Third axis AX3 is perpendicular to both first and second axes AX1 and AX2. When viewed along first axis AX1, the elongated magnetically permeable element CM extends along second axis AX2.

[0119] like Figure 2 As shown, the first groove 1121 extends along the second axis AX2. Figure 4 As shown, when viewed along the first axis AX1 , the fixing element FA having a polygonal structure includes a first side SS1 and a second side SS2 parallel to each other.

[0120] When viewed along the first axis AX1, the shortest distance between the first trench 1121 and the first side SS1 is different from the shortest distance between the first trench 1121 and the second side SS2. Figure 4 As shown, the shortest distance between the first trench 1121 and the first side SS1 is greater than the shortest distance between the first trench 1121 and the second side SS2.

[0121] like Figure 4 As shown, when viewed along the first axis AX1, the first groove 1121 does not overlap with the magnetic element CM. When viewed along the first axis AX1, the first groove 1121 does not overlap with the center (eg, the central axis) of the coil CL.

[0122] The first supporting base 1081 is configured to support the first magnetic element MG1, and the first supporting base 1081 may have a first upper cover 1083. The width of the first upper cover 1083 along the third axis AX3 is greater than the width of the first groove 1121 along the third axis AX3. Figure 3 As shown, the first upper cover 1083 is configured to abut against an upper surface 112S of the base 112 of the fixing assembly FA.

[0123] In this embodiment, the first optical mechanism 100 further includes a supporting assembly SA configured to fix the fixing assembly FA to the base 15. When viewed along the first axis AX1, the first opening OP1 is located between the supporting assembly SA and the first driving assembly DA1.

[0124] The support assembly SA and the fixing assembly FA form a first accommodating space AS1, with at least a portion of the second optical mechanism 200 located in the first accommodating space AS1. Similarly, a second opening OP2 is located between the support assembly SA and the first driving assembly DA1. The support assembly SA and the fixing assembly FA form a second accommodating space AS2, with at least a portion of the third optical mechanism 300 located in the second accommodating space AS2.

[0125] For example, the support assembly SA may include two first support elements SP1 and two second support elements SP2, and the first support elements SP1 and the second support elements SP2 may have a columnar structure, but are not limited thereto. In other embodiments, the support elements may have a flat plate structure or a U-shaped plate structure.

[0126] It is worth noting that the first support element SP1 and the second support element SP2 may include shock-absorbing materials. Based on the design of the support assembly SA, the problem of the first end EP1 or the second end EP2 being disconnected from the middle portion MP of the base 112 when the optical system 10 is impacted can be avoided.

[0127] In this embodiment, the optical system 10 can selectively cover the first opening OP1 or the second opening OP2. For example, when the first movable portion 108 is located relative to the fixed element FA, Figure 1 When the first movable portion 108 is at a first preset position and viewed along the first axis AX1, the first optical element 1082 overlaps the first opening OP1. When the first movable portion 108 is at the first preset position and viewed along the first axis AX1, the first optical element 1082 does not overlap the second opening OP2.

[0128] When the second opening OP2 is to be closed, the coil CL can receive a current to generate a first electromagnetic driving force EF1 with the first magnetic element MG1 to drive the first movable portion 108 to move from a first direction D1 to a first direction D2. Figure 1 Move to the first preset position in Figure 4 When the first movable portion 108 is located relative to the fixed component FA Figure 4 When the first movable portion 108 is at the second preset position and viewed along the first axis AX1, the first optical element 1082 overlaps the second opening OP2. When the first movable portion 108 is at the second preset position and viewed along the first axis AX1, the first optical element 1082 does not overlap the first opening OP1.

[0129] like Figure 4 As shown, when viewed along the first axis AX1, the first drive assembly DA1 is located between the first opening OP1 and the second opening OP2. Figure 3 As shown, the guide assembly GA may further include a first track TK1 formed on the base 112 of the fixing assembly FA, ​​and the first movable portion 108 is configured to move along the first track TK1 .

[0130] In addition, the guide assembly GA may further include a second track TK2 formed on the base 15, but is not limited thereto. In other embodiments, the second track TK2 may also be formed on the base 112. Similarly, the first movable portion 108 may be configured to move along the second track TK2.

[0131] like Figure 3 As shown, when viewed along the second axis AX2, the first track TK1 and the second track TK2 are located on opposite sides of the first movable portion 108, such as above and below the first supporting base 1081. Based on the arrangement of the first track TK1 and the second track TK2, the first movable portion 108 can be stably moved along the direction of the second axis AX2.

[0132] When the first opening OP1 is to be closed again, the first driving assembly DA1 can generate a first electromagnetic driving force EF1 in the opposite direction to drive the first movable portion 108 to move from a first direction to a second direction D1. Figure 4 Move to the second preset position in Figure 1 The first preset position in the middle. The first direction D1 is opposite to the second direction D2.

[0133] Please refer to Figures 5 to 8 , Figure 5 is a perspective view of an optical system 10A according to an embodiment of the present disclosure, Figure 6 FIG. 1 is an exploded view of an optical system 10A according to an embodiment of the present disclosure. Figure 7 is a top view of a partial structure of an optical system 10A according to an embodiment of the present disclosure, and Figure 8 FIG. 1 is a side view of a partial structure of an optical system 10A according to an embodiment of the present disclosure.

[0134] The optical system 10A of this embodiment is similar to the optical system 10 and comprises a first optical mechanism 100A, a second optical mechanism 200 and a third optical mechanism 300. The first optical mechanism 100A comprises a fixing assembly FA, ​​a first movable portion 108 and a first driving assembly DA1. Figure 7 As shown, when viewed along the first axis AX1, the first opening OP1 is located between the second opening OP2 and the first drive assembly DA1. Figure 8 As shown, the second optical mechanism 200 and the third optical mechanism 300 are disposed on the base 15 and are located on the same plane (XY plane).

[0135] A second lens 202 of the second optical mechanism 200 corresponds to the first opening OP1 and is configured to receive the first light LT1. A third lens 302 of the third optical mechanism 300 corresponds to the second opening OP2 and is configured to receive the second light LT2. The size of the first opening OP1 is the same as the size of the second opening OP2, but the aperture of the second lens 202 is different from the aperture of the third lens 302.

[0136] For example, the aperture of the second lens 202 is larger than that of the third lens 302 , and a distance d1 between the second lens 202 and the first opening OP1 on the first axis AX1 is smaller than a distance d2 between the third lens 302 and the second opening OP2 on the first axis AX1 .

[0137] The operation of the optical system 10A is as follows. When the first movable portion 108 is located relative to the fixed component FA Figure 5 When the first movable portion 108 is at the first preset position and viewed along the first axis AX1, the first optical element 1082 overlaps the first opening OP1. When the first movable portion 108 is at the first preset position and viewed along the first axis AX1, the first optical element 1082 does not overlap the second opening OP2.

[0138] Furthermore, the first driving component DA1 can generate an electromagnetic driving force (eg, a first electromagnetic driving force EF1) to drive the first movable portion 108 to move to the second preset position, thereby closing the second opening OP2. Figure 7 When the first movable portion 108 is in the second preset position and viewed along the first axis AX1, the first optical element 1082 overlaps with the second opening OP2. When the first movable portion 108 is in the second preset position and viewed along the first axis AX1, the first optical element 1082 does not overlap with the first opening OP1. Specifically, a transmissive portion 1082H may be formed on the first optical element 1082 to allow light (e.g., the first light ray LT1) to pass through the transmissive portion 1082H to the second optical mechanism 200. The transmissive portion 1082H may be, for example, an opening, but is not limited thereto.

[0139] In addition, in this embodiment, Figure 8 As shown, when viewed along the third axis AX3 , the base 112 has an L-shaped structure, and two first supporting elements SP1 may be disposed at the first end EP1 of the base 112 to support the first optical mechanism 100 on the base body 15 .

[0140] Please continue to refer to Figures 9 to 12 , Figure 9 is a perspective view of an optical system 10B according to an embodiment of the present disclosure, Figure 10 FIG. 1 is an exploded view of an optical system 10B according to an embodiment of the present disclosure. Figure 11 The optical system 10B according to an embodiment of the present disclosure is Figure 9 The solid cross-section of line segment BB, and Figure 12 FIG. 1 is a top view of a partial structure of an optical system 10B according to an embodiment of the present disclosure.

[0141] The optical system 10B of this embodiment is similar to the aforementioned optical system 10, and comprises a first optical mechanism 100B, a second optical mechanism 200, and a third optical mechanism 300. The first optical mechanism 100B comprises a fixing assembly FA, ​​a first movable portion 108, and a first driving assembly DA1. Figure 12 As shown, when viewed along the first axis AX1 , the first drive assembly DA1 is located between the first opening OP1 and the second opening OP2 .

[0142] In this embodiment, the first optical mechanism 100 further includes a second movable portion 109 configured to move along the second axis AX2 relative to the fixed assembly FA. The second movable portion 109 includes a second supporting base 1091 and a second optical element 1092, with the second supporting base 1091 configured to connect to and support the second optical element 1092. Furthermore, the first driving assembly DA1 may further include a second magnetic element MG2 corresponding to the coil CL, and the second supporting base 1091 configured to support the second magnetic element MG2.

[0143] Similarly, the second supporting base 1091 has a second upper cover plate 1093 , and the second upper cover plate 1093 is configured to abut against the upper surface 112S.

[0144] In addition to the first groove 1121, the guide assembly GA may further include a second groove 1122 configured to accommodate the second support base 1091 and the second magnetic element MG2, and to generate friction between the second support base 1091 and the second groove 1122. The second groove 1122 extends along the second axis AX2, and the width of the second upper cover plate 1093 along the third axis AX3 is greater than the width of the second groove 1122 along the third axis AX3.

[0145] In this embodiment, if Figure 11 As shown, when viewed along the second axis AX2, the coil CL is located between the first magnetic element MG1 and the second magnetic element MG2. When the coil CL receives a current, the first magnetic element MG1 and the second magnetic element MG2 induce a first electromagnetic driving force EF1 and a second electromagnetic driving force EF2 with the coil CL, respectively.

[0146] The first electromagnetic driving force EF1 and the second electromagnetic driving force EF2 drive the first movable portion 108 and the second movable portion 109 to move simultaneously along a first direction D1 and a second direction D2 respectively. Figure 9 Move the first preset position in Figure 12The first direction D1 and the second direction D2 are parallel to the second axis AX2, and the first direction D1 is opposite to the second direction D2.

[0147] It should be noted that, in this embodiment, the first magnetic element MG1 and the second magnetic element MG2 have different sizes, different materials, different formation methods, and different weights.

[0148] In this embodiment, the base 112 of the fixing assembly FA may further include a partition element 112P extending from the upper surface 112S along the first axis AX1 . When viewed along the first axis AX1 , the partition element 112P is located between the first groove 1121 and the second groove 1122 .

[0149] like Figure 11 As shown, a first magnetic attraction force TF1 is generated between the first magnetic element MG1 and the magnetically permeable element CM. When viewed along the second axis AX2, the first magnetic attraction force TF1 forces the first upper cover plate 1083 to abut the partition element 112P. Similarly, a second magnetic attraction force TF2 is generated between the second magnetic element MG2 and the magnetically permeable element CM. When viewed along the second axis AX2, the second magnetic attraction force TF2 forces the second upper cover plate 1093 to abut the partition element 112P.

[0150] Based on the above structural configuration, the partition element 112P can prevent the first movable portion 108 and the second movable portion 109 from colliding with each other, so that the first movable portion 108 and the second movable portion 109 can move smoothly along the first groove 1121 and the second groove 1122 respectively.

[0151] Please refer to Figure 13 , Figure 13 FIG2 is an enlarged view of an optical system 10B according to an embodiment of the present disclosure. In this embodiment, the guide assembly GA may further include a first lateral rail LK1 formed on the base 112 of the fixed assembly FA. The first lateral rail LK1 is configured to guide the first optical element 1082. The guide assembly GA may further include a second lateral rail LK2 formed on the base 112 of the fixed assembly FA. The second lateral rail LK2 is configured to guide the second optical element 1092.

[0152] like Figure 13 As shown, when the first movable portion 108 and the second movable portion 109 are located at the second preset position relative to the fixed component FA, and when observed along the second axis AX2, the shortest distance DM1 between the first optical element 1082 and the upper surface 112S is different from the shortest distance DM2 between the second optical element 1092 and the upper surface 112S.

[0153] Specifically, a shortest distance DM1 between the first optical element 1082 and the upper surface 112S is greater than a shortest distance DM2 between the second optical element 1092 and the upper surface 112S. Figure 12 and Figure 13 As shown, when the first movable portion 108 and the second movable portion 109 are located at the second preset position relative to the fixing assembly FA, ​​and when viewed along the first axis AX1, the first optical element 1082 overlaps at least a portion of the second optical element 1092 .

[0154] In addition, if Figure 12 As shown, in order to ensure that the first movable portion 108 and the second movable portion 109 move stably, the lengths of the two first lateral rails LK1 can be different, and the lengths of the two second lateral rails LK2 can also be different. For example, Figure 12 The length of the lower first lateral rail LK1 is greater than that of the upper first lateral rail LK1. Based on the above structure, the first movable portion 108 and the second movable portion 109 can be prevented from colliding with each other and causing damage when moving toward the center of the first optical mechanism 100B.

[0155] In the optical system 10B, the first opening OP1 and the second opening OP2 are opened or closed at the same time. For example, when the first movable portion 108 and the second movable portion 109 are located relative to the fixed element FA, Figure 9 When the optical element 1082 is at the first preset position in the optical system, and when viewed along the first axis AX1, the first optical element 1082 overlaps with the first opening OP1. At this time, when viewed along the first axis AX1, the second optical element 1092 overlaps with the second opening OP2.

[0156] When the first movable portion 108 and the second movable portion 109 are located at the second preset position relative to the fixing assembly FA, ​​and when viewed along the first axis AX1, as shown in FIG. Figure 12 As shown, the first optical element 1082 does not overlap with the first opening OP1. At this time, when viewed along the first axis AX1, the second optical element 1092 does not overlap with the second opening OP2.

[0157] When the first opening OP1 and the second opening OP2 are to be opened again at the same time, the coil CL can receive a current in opposite phase to the above current, so that the first electromagnetic driving force EF1 and the second electromagnetic driving force EF2 push the first movable part 108 and the second movable part 109 back to Figure 9 The first preset position in .

[0158] Please refer to Figures 14 to 16 , Figure 14 is a perspective view of an optical system 10C according to an embodiment of the present disclosure, Figure 15 is an exploded view of an optical system 10C according to an embodiment of the present disclosure, and Figure 16 FIG2 is a top view of a portion of an optical system 10C according to an embodiment of the present disclosure. Similar to optical system 10A, optical system 10C of this embodiment comprises a first optical mechanism 100C, a second optical mechanism 200, and a third optical mechanism 300. The first optical mechanism 100 includes a fixed assembly FA, ​​a first movable portion 108, and a first driving assembly DA1.

[0159] When viewed along the first axis AX1 , the first opening OP1 is located between the second opening OP2 and the first driving assembly DA1 . Similarly, the first optical element 1082 has a transmissive portion 1082H, and the transmissive portion 1082H has a rectangular structure.

[0160] When the first movable portion 108 is located relative to the fixed component FA Figure 14 When the optical element 1082 is at the first predetermined position in the optical element 1082, and when viewed along the first axis AX1, the transmissive portion 1082H is located between the first opening OP1 and the second opening OP2, and the transmissive portion 1082H overlaps the base 112. In this case, the first optical element 1082 overlaps the first opening OP1 and the second opening OP2. In other words, the first opening OP1 and the second opening OP2 are both shielded by the first optical element 1082.

[0161] In addition, when the first driving component DA1 drives the first movable part 108 to move to Figure 16 When the optical element 1082 is at the second preset position and viewed along the first axis AX1, the first optical element 1082 does not overlap with the first opening OP1 and the second opening OP2, and the penetrating portion 1082H overlaps with the first opening OP1. At this time, the first opening OP1 and the second opening OP2 are simultaneously opened.

[0162] In this embodiment, the support assembly SA may further include two first support elements SP1 and two second support elements SP2. The first support element SP1 is disposed at the first end EP1, and the second support element SP2 is located between the second optical mechanism 200 and the third optical mechanism 300. Based on the design of the support assembly SA, damage to the first end EP1 when the optical system 10 is subjected to an impact can be further avoided.

[0163] The manner in which the first driving assembly DA1 drives the first movable portion 108 to move relative to the fixing assembly FA is the same as that of the optical system 10A, and thus will not be further described herein.

[0164] The present disclosure provides an optical system including a first optical mechanism, a second optical mechanism 200, and a third optical mechanism 300. The base 112 of the first optical mechanism has a first opening OP1 and a second opening OP2 corresponding to the second optical mechanism 200 and the third optical mechanism 300, respectively. In some embodiments, the first driving assembly DA1 of the first optical mechanism can drive the first movable portion 108 to selectively cover the first opening OP1, the second opening OP2, or both the first opening OP1 and the second opening OP2.

[0165] In some embodiments, the first driving assembly DA1 of the first optical mechanism may include two magnetic elements and corresponding coils CL to respectively drive the first movable portion 108 and the second movable portion 109 to move to simultaneously cover or open the first opening OP1 and the second opening OP2. The various embodiments of the present disclosure can be applied to different electronic devices according to actual needs.

[0166] Based on the above structural configuration, the optical system can achieve the advantages of miniaturization, reduction in the number of components and reduction in production costs.
