In fact, the optical system 100 can be installed at different positions in the electronic device 1 according to different needs.

[0086] Refer to Figure 2 and Figure 3 . Figure 2 is a schematic diagram of an optical system 100, a first optical element OE1, a second optical element OE2, a third optical element OE3, a first optical module optical element OE4, a second optical module optical element OE5, and a third optical module optical element OE6 according to some embodiments of the present application, in which the outer frame 111 is represented by a dashed line. Figure 3 is an exploded view of an optical system 100, a first optical element OE1, a second optical element OE2, a third optical element OE3, a first optical module optical element OE4, a second optical module optical element OE5, and a third optical module optical element OE6 according to some embodiments of the present application.

[0087] The optical system 100 may include a system fixing portion 110 , a first optical module 120 , a second optical module 130 , a third optical module 140 , and a connecting assembly 150 .

[0088] The system fixing portion 110 may include a system housing 111 and a system base 112. The system housing 111 is disposed on the system base 112, and the system housing 111 and the system base 112 may be connected to each other to form an internal space for accommodating other components of the optical system 100 or the first optical element OE1, the second optical element OE2, the third optical element OE3, the first optical module optical element OE4, the second optical module optical element OE5, and the third optical module optical element OE6.

[0089] The first optical module 120 may be disposed on the system base 112 and may include a first optical module movable portion 121 and a first optical module driving assembly 122. The first optical module movable portion 121 may be connected to and carry the first optical module optical element OE4, and the first optical module driving assembly 122 may drive the first optical module movable portion 121 to move relative to the system base 112 along a second axis AX2 perpendicular to the first axis AX1, thereby allowing the first optical module optical element OE4 to move relative to the system base 112 along the second axis AX2.

[0090] The second optical module 130 may be disposed on a first top surface 111A of the system housing 111 , and may include a second optical module fixing portion 131 , a second optical module movable portion 132 , and a second optical module driving assembly 133 .

[0091] The second optical module fixing portion 131 may include a second optical module housing 1311 and a second optical module base 1312. The second optical module movable portion 132 may be disposed between the second optical module housing 1311 and the second optical module base 1312, and the second optical module movable portion 132 may be connected to and carry the second optical module optical element OE5.

[0092] The second optical module driving assembly 133 can drive the second optical module movable portion 132 to rotate about the first axis AX1, so that the blades (not shown) inside the second optical module fixed portion 131 can be opened or closed, thereby controlling the amount of light entering the second optical module optical element OE5.

[0093] The third optical module 140 can be disposed on the system base 112 and located within a receiving space formed by the system housing 111 and the system base 112. Specifically, the third optical module 140 can be disposed on a first system base surface 112A and a second system base surface 112B of the system base 112. However, it should be noted that the second optical module 130 is not located within the first receiving space.

[0094] The system base first surface 112A and the system base second surface 112B may face the third optical module 140. For example, the system base first surface 112A and the system base second surface 112B may face the same direction and may be perpendicular to the first axis AX1.

[0095] The third optical module 140 may include a third optical module fixing portion 141 , a third optical module movable portion 142 , a third optical module first driving component 143 , and a third optical module second driving component 144 .

[0096] The third optical module fixed portion 141 may include a third optical module base 1411. The third optical module movable portion 142 may be disposed between the system housing 111 and the third optical module base 1411 and may be connected to and support the third optical element OE3. The third optical module first driving assembly 143 may drive the third optical module movable portion 142 to move relative to the third optical module base 1411 in a direction perpendicular to the first axis AX1, thereby enabling the third optical element OE3 to move relative to the third optical module base 1411 in a direction perpendicular to the first axis AX1. Simultaneously, the third optical module first driving assembly 143 may drive the third optical module movable portion 142 to move along the X-axis and the Y-axis, thereby enabling the third optical element OE3 to move relative to the third optical module base 1411 in the X-axis and the Y-axis. This enables the third optical element OE3 to achieve autofocus (AF) and optical image stabilization (OIS) effects. The third optical module second driving assembly 144 drives the third optical module optical element OE6 to move relative to the third optical module base 1411 along a direction perpendicular to the first axis AX1.

[0097] The connecting assembly 150 may include a first connecting element 151 and a second connecting element 152. The first connecting element 151 and the second connecting element 152 may have adhesive properties. For example, the first connecting element 151 and the second connecting element 152 may be made of glue, solder, or other materials.

[0098] See also Figure 4 , Figure 4is a sectional view along the A-A' line of the optical system 100, the first optical element OE1, the second optical element OE2, the third optical element OE3, the first optical module optical element OE4, the second optical module optical element OE5, and the third optical module optical element OE6 according to some embodiments of the present application. Figure 2

[0099] As shown in Figure 4 , the first optical element OE1 is connected to the system base 112, and the second optical element OE2 is also connected to the system base 112. Moreover, the system base 112 can include a first connecting structure 1121 and a second connecting structure 1122.

[0100] The first connecting structure 1121 can correspond to the first optical element OE1, for example, the first connecting structure 1121 can protrude from the system base 112 toward the first optical element OE1. The first connecting structure 1121 can support the first optical element OE1 such that there is a gap between the first optical element OE1 and the system base 112.

[0101] The second connecting structure 1122 can correspond to the second optical element OE2, for example, the second connecting structure 1122 can protrude from the system base 112 toward the second optical element OE2. The second connecting structure 1122 can support the second optical element OE2 such that there is a gap between the second optical element OE2 and the system base 112.

[0102] According to some embodiments of the present application, the gap between the first optical element OE1 and the system base 112, and the gap between the second optical element OE2 and the system base 112 can contain air and no other substance to avoid affecting the optical properties of the optical system 100

[0103] According to some embodiments of the present application, the gap between the first optical element OE1 and the system base 112, and the gap between the second optical element OE2 and the system base 112 can contain a material that enhances the optical properties.

[0104] The first connecting structure 1121 can include a first connecting surface 1121A, and the second connecting structure 1122 can include a second connecting surface 1122A. The first connecting surface 1121A can face and contact the first optical element OE1, but the direction that the first connecting surface 1121A faces can not be perpendicular and parallel to the system base first surface 112A and the system base second surface 112B.

[0105] ​In other words, the direction facing the first connection surface 1121A may be neither perpendicular nor parallel to the first axis AX1. The second connection surface 1122A may face and contact the second optical element OE2, but the direction facing the second connection surface 1122A may be neither perpendicular nor parallel to the system base first surface 112A and the system base second surface 112B. In other words, the direction facing the second connection surface 1122A may be neither perpendicular nor parallel to the first axis AX1.

[0106] like Figure 4 As shown, the second optical module 130 and the first optical element OE1 can be arranged along the first axis AX1. The first optical element OE1, the first optical module 120, and the second optical element OE2 can be arranged along the second axis AX2. The second optical element OE2 and the third optical module 140 can be arranged along the first axis AX1.

[0107] In other words, when viewed along the first axis AX1, the second optical module 130 and the first optical element OE1 may at least partially overlap. When viewed along the second axis AX2, the first optical element OE1 and the first optical module 120 may at least partially overlap. When viewed along the second axis AX2, the first optical element OE1 and the second optical element OE2 may at least partially overlap.

[0108] Furthermore, when viewed along the second axis AX2, the first optical module 120 and the second optical element OE2 may at least partially overlap. When viewed along the second axis AX2, the first optical element OE1, the first optical module 120, and the second optical element OE2 may at least partially overlap. When viewed along the first axis AX1, the second optical element OE2 and the third optical module 140 may at least partially overlap.

[0109] Please continue reading Figure 4 The second optical module optical element OE5 and the first optical element OE1 are arranged along the first axis AX1. The first optical element OE1, the first optical module optical element OE4, and the second optical element OE2 are arranged along the second axis AX2. The second optical element OE2, the third optical module optical element OE6, and the third optical element OE3 are arranged along the first axis AX1.

[0110] Furthermore, the first optical module optical element OE4 is disposed between the first optical element OE1 and the second optical element OE2 so that the first optical element OE1 does not contact the second optical element OE2.

[0111] Since the first optical module 120 has a larger moving distance, the first optical module 120 can effectively increase the focusing distance of the optical system 100 .

[0112] Since the second optical module 130 is far away from the third optical module 140 , the second optical module 130 can enable the optical system 100 to be accurately focused.

[0113] Since the third optical module 140 is disposed on the opposite side of the first optical module 120 , the optical system 100 can effectively utilize space and can further achieve more precise focusing.

[0114] There may be a gap between the first optical module optical element OE4 and the first optical element OE1, and there may be a gap between the first optical module optical element OE4 and the second optical element OE2. In this way, the first optical module optical element OE4 can move along the second axis AX2.

[0115] According to some embodiments of the present invention, the gap between the first optical module optical element OE4 and the first optical element OE1, and the gap between the first optical module optical element OE4 and the second optical element OE2 can contain air but not other substances to avoid affecting the optical properties of the optical system 100.

[0116] According to some embodiments of the present invention, the gap between the first optical module optical element OE4 and the first optical element OE1 , and the gap between the first optical module optical element OE4 and the second optical element OE2 may contain a material that improves optical properties.

[0117] like Figure 4 As shown, a light ray L can be incident on the second optical module 130 from outside the optical system 100. The second optical module 130 can transmit the light ray L to the first optical element OE1. The first optical element OE1 can transmit the light ray L to the first optical module 120. The first optical module 120 can transmit the light ray L to the second optical element OE2. The second optical element OE2 can transmit the light ray L to the third optical module 140.

[0118] Specifically, light L may be incident on the second optical module optical element OE5 from outside the optical system 100 along the first axis AX1. The second optical module optical element OE5 may transmit the light L along the first axis AX1 to the first optical element OE1. The first optical element OE1 may refract and / or reflect the light L from the first axis AX1 along the second axis AX2, and the first optical element OE1 may transmit the light L along the second axis AX2 to the first optical module optical element OE4.

[0119] Next, the first optical module optical element OE4 can transmit the light L along the second axis AX2 to the second optical element OE2. The second optical element OE2 can refract and / or reflect the light L from the second axis AX2 to the first axis AX1, and the second optical element OE2 can transmit the light L along the first axis AX1 to the third optical module optical element OE6. The third optical module optical element OE6 can transmit the light L along the first axis AX1 to the third optical element OE3.

[0120] Please continue reading Figure 4 A gap may be provided between the third optical module base 1411 and the first optical element OE1, and a gap may be provided between the third optical module base 1411 and the first optical element OE4.

[0121] According to some embodiments of the present invention, the gap between the third optical module base 1411 and the first optical element OE1, and the gap between the third optical module base 1411 and the first optical element OE4 can contain air but not other substances to avoid affecting the optical properties of the optical system 100.

[0122] According to some embodiments of the present invention, the gap between the third optical module base 1411 and the first optical element OE1 and the gap between the third optical module base 1411 and the first optical element OE4 may contain materials that improve optical properties.

[0123] Please continue reading Figure 4 The first connecting element 151 can directly contact the first surface 112A of the system base and the third optical module 140 to secure the third optical module 140 to the first surface 112A of the system base. The second connecting element 152 can directly contact the second surface 112B of the system base and the third optical module 140 to secure the third optical module 140 to the second surface 112B of the system base. In this way, an effective and stable connection can be formed.

[0124] Furthermore, according to some embodiments of the present invention (not shown in the drawings), the first connecting element 151 can directly contact the second connecting element 152. In this way, the connection effect can be enhanced, thereby strengthening the structure of the optical system 100.

[0125] According to some embodiments of the present invention, the system base second surface 112B may be “lower” than the system base first surface 112A. For example, the system base second surface 112B is further away from a system housing second top surface 111B of the system housing 111 than the system base first surface 112A.

[0126] Please continue reading Figure 4When viewed along the first axis AX1, the system housing first top surface 111A and the system housing second top surface 111B may not overlap. When viewed along the first axis AX1, the system housing first top surface 111A and the system base first surface 112A may not overlap. When viewed along the first axis AX1, the system housing first top surface 111A and the system base second surface 112B may not overlap.

[0127] When viewed along the first axis AX1, the system housing second top surface 111B and the system base first surface 112A may at least partially overlap. When viewed along the first axis AX1, the system housing second top surface 111B and the system base second surface 112B may at least partially overlap. When viewed along the first axis AX1, the system base first surface 112A and the system base second surface 112B may not overlap.

[0128] In this way, the structure of the optical system 100 can be made more stable, and space can be used effectively, thereby achieving a miniaturization effect.

[0129] Please continue reading Figure 4 When viewed along the second axis AX2, the system housing first top surface 111A and the system housing second top surface 111B may not overlap. When viewed along the second axis AX2, the system housing first top surface 111A and the system base first surface 112A may not overlap. When viewed along the second axis AX2, the system housing first top surface 111A and the system base second surface 112B may not overlap.

[0130] When viewed along the second axis AX2, the second top surface 111B of the system housing and the first surface 112A of the system base may not overlap. When viewed along the second axis AX2, the second top surface 111B of the system housing and the second surface 112B of the system base may not overlap. When viewed along the second axis AX2, the first surface 112A of the system base and the second surface 112B of the system base may not overlap.
