Description

Technical Field

[0001] This disclosure relates to an optical system, and more particularly to an optical system having a liquid lens. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones) have the function of taking pictures or recording videos. Through the camera module set on the electronic device, users can operate the electronic device to extract all kinds of photos.

[0003] The design of modern electronic devices is constantly trending towards miniaturization, necessitating the continuous shrinking of various components and structures within camera modules to achieve this goal. Generally, the drive mechanism in a camera module may include a lens mount to support a lens, and the drive mechanism may possess autofocus or optical image stabilization capabilities. However, while existing drive mechanisms can achieve the aforementioned photographic or video recording functions, they still cannot meet all requirements.

[0004] Therefore, how to design a camera module that can simultaneously perform autofocus, optical image stabilization, and achieve miniaturization is a topic worthy of discussion and resolution. Summary of the Invention

The movable component has a first movable member surface and a third movable member surface, the first movable member surface facing the first drive component and the third movable member surface facing the third drive component. The optical system defines an imaginary plane perpendicular to the main axis. When the drive module drives the movable component to move and is observed along a direction perpendicular to the main axis, an angle between the movable element surface and the imaginary plane is less than or equal to an angle between the line connecting the centers of the first and third movable member surfaces and the imaginary plane.

[0010] According to some embodiments of this disclosure, the movable component includes a first movable member and a second movable member, a first driving component is configured to drive the first movable member to move relative to a fixed component, and a second driving component is configured to drive the second movable member to move relative to the fixed component and the first movable member.

[0011] According to some embodiments of this disclosure, the connecting assembly includes a connector, and the movable assembly is connected to the movable element via an elastic portion of the connector.

[0012] According to some embodiments of this disclosure, the elastic portion has a plate-like structure that is generally parallel to the main axis.

[0773] First set of embodiments.

[0774] Please refer to Figures 1 to 3 , Figure 1 This is a perspective view of an optical system 1-100 according to an embodiment of the present disclosure. Figure 2This is an exploded view of an optical system 1-100 according to an embodiment of the present disclosure, and Figure 3 According to an embodiment of the present disclosure Figure 1 The optical system 1-100 is shown in cross-sectional view along line segment 1-A-1-A'. The optical system 1-100 can be an optical imaging system configured to carry and drive a first optical element 1-OE, which defines an optical axis 1-O. The optical system 1-100 can be installed in various electronic devices or portable electronic devices, such as smartphones, for users to perform image extraction functions. In this embodiment, the optical system 1-100 can be a voice coil motor (VCM) with autofocus (AF) functionality, but this disclosure is not limited thereto. In other embodiments, the optical system 1-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.

[0775] like Figure 2 As shown, in this embodiment, the optical system 1-100 may include a fixed component 1-FA, a shaping component 1-101, a movable element 1-103, a connecting component 1-CA, a movable component 1-MA, and a driving module 1-DM. The shaping component 1-101 is connected between the movable element 1-103 and the first optical element 1-OE. The movable element 1-103 is movable relative to the fixed component 1-FA, and the driving module 1-DM is configured to drive the movable element 1-103 to move relative to the fixed component 1-FA. Specifically, the movable component 1-MA is movably connected to the movable element 1-103 via the connecting component 1-CA, and the driving module 1-DM drives the movable component 1-MA to move relative to the fixed component 1-FA, thereby driving the movable element 1-103.

[0776] In this embodiment, as Figure 2 as well as Figure 3 As shown, the fixing assembly 1-FA includes a housing 1-102, a frame 1-104, and a base 1-112. The housing 1-102 is fixedly connected to the base 1-112, and the frame 1-104 is also fixedly connected to the inner wall surface of the housing 1-102. The fixing assembly 1-FA may define a main axis 1-AX. When the optical system 1-100 is not activated, the main axis 1-AX is parallel to or overlaps with the optical axis 1-O of the first optical element 1-OE. In addition, the movable element 1-103 has a movable element surface 1-103S facing the first optical element 1-OE.

[0777] like Figure 2 as well as Figure 3As shown, the aforementioned housing 1-102 has a hollow structure with a housing opening 1-1021 formed thereon, and the base 1-112 has a base opening 1-1121 formed thereon. The center of the housing opening 1-1021 corresponds to the optical axis 1-O of the first optical element 1-OE, and the base opening 1-1121 corresponds to the photosensitive element (not shown) disposed below the base 1-112. In this embodiment, the first optical element 1-OE is fixedly disposed within the housing opening 1-1021. External light can enter the housing 1-102 through the first optical element 1-OE and pass through the base opening 1-1121 before being received by the aforementioned photosensitive element to generate a digital image signal.

[0778] Furthermore, the housing 1-102 is disposed on the base 1-112 and may have an accommodating space 1-1023 configured to accommodate the movable element 1-103, the frame 1-104, the movable component 1-MA, the connecting component 1-CA, and the drive module 1-DM.

[0779] like Figure 2 and Figure 3 As shown, in this embodiment, the movable component 1-MA may include four movable members (first movable member 1-1081, second movable member 1-1082, third movable member 1-1083, and fourth movable member 1-1084), and the connecting component 1-CA may include four connectors (first connector 1-1051, second connector 1-1052, third connector 1-1053, and fourth connector 1-1054). The first movable member 1-1081 to the fourth movable member 1-1084 are respectively connected to the movable element 1-103 through the first connector 1-1051 to the fourth connector 1-1054.

[0780] Additionally, the optical system 1-100 may further include a first elastic element 1-106 and a second elastic element 1-110, and the base 1-112 may include four protrusions 1-1123. The outer portion (outer ring portion) of the first elastic element 1-106 is fixedly disposed on the top surface of the protrusion 1-1123, the outer portion (outer ring portion) of the second elastic element 1-110 is fixedly disposed on a plane 1-1125 of the protrusion 1-1123, and the inner portions (inner ring portions) of the first elastic element 1-106 and the second elastic element 1-110 are respectively connected to the upper and lower sides of the movable component 1-MA, so that the first movable component 1-1081 to the fourth movable component 1-1084 are suspended in the accommodating space 1-1023.

[0781] In this embodiment, the drive module 1-DM may include four drive components (first drive component 1-DA1, second drive component 1-DA2, third drive component 1-DA3, and fourth drive component 1-DA4). The first drive component 1-DA1 includes a first drive coil 1-CL1 and a first magnetic element 1-MG1, the second drive component 1-DA2 includes a second drive coil 1-CL2 and a second magnetic element 1-MG2, the third drive component 1-DA3 includes a third drive coil 1-CL3 and a third magnetic element 1-MG3, and the fourth drive component 1-DA4 includes a fourth drive coil 1-CL4 and a fourth magnetic element 1-MG4.

[0782] In this embodiment, each magnetic element has a magnetic surface. For example, such as Figure 2 As shown, the first magnetic element 1-MG1 and the second magnetic element 1-MG2 each have a first magnetic surface 1-MS1 and a second magnetic surface 1-MS2. The first magnetic surface 1-MS1 faces the first driving coil 1-CL1, and the second magnetic surface 1-MS2 faces the second driving coil 1-CL2. The first magnetic surface 1-MS1 and the second magnetic surface 1-MS2 face different directions.

[0783] In this embodiment, as Figure 2 As shown, the frame 1-104 has multiple grooves 1-1041 and a central opening 1-1043. In this embodiment, the frame 1-104 has four grooves 1-1041 configured to accommodate the aforementioned four magnetic elements, but the number of grooves 1-1041 and magnetic elements is not limited to this embodiment. The central opening 1-1043 is configured to accommodate the first drive coil 1-CL1 to the fourth drive coil 1-CL4 and the first movable member 1-1081 to the fourth movable member 1-1084.

[0784] In this embodiment, the first driving coil 1-CL1 to the fourth driving coil 1-CL4 can be wound coils, respectively disposed on the first movable member 1-1081 to the fourth movable member 1-1084. When the first driving coil 1-CL1 to the fourth driving coil 1-CL4 are energized, they can generate electromagnetic driving force with the first magnetic element 1-MG1 to the fourth magnetic element 1-MG4 respectively, thereby driving the first movable member.

[0785] At least one of the four movable components 1-1081 to 1-1084 moves relative to the base 1-112 and the frame 1-104 along the direction of the optical axis 1-O (Z-axis direction) to perform autofocusing or optical image stabilization.

[0786] The drive components of drive module 1-DM can operate individually or together. For example, the first drive component 1-DA1 is configured to drive the first movable member 1-1081 to move relative to the fixed component 1-FA, and the second drive component 1-DA2 is configured to drive the second movable member 1-1082 to move relative to the fixed component 1-FA and the first movable member 1-1081, and so on.

[0787] Furthermore, such as Figure 2 As shown, in this embodiment, the fixing component 1-FA may further include at least one circuit component 1-170, configured to be electrically connected to the drive module 1-DM via a first elastic element 1-106 or a second elastic element 1-110. The circuit component 1-170 may be implemented by insert molding, but is not limited thereto.

[0788] Next, please refer to Figures 4 to 6 , Figure 4 This is a schematic diagram showing the first optical element 1-OE according to an embodiment of the present disclosure not being pushed by the molding part 1-101. Figure 5 as well as Figure 6 This is a schematic diagram showing the first optical element 1-OE according to an embodiment of the present disclosure after being pushed by the molding member 1-101. Figure 4 As shown, the first optical element 1-OE can be a liquid lens, comprising a liquid lens element 1-OE1 and a fixing member 1-OE2. The liquid lens element 1-OE1 is disposed within the fixing member 1-OE2, which has a hollow structure. The fixing member 1-OE2 has the function of protecting and supporting the liquid lens element 1-OE1. The shaping member 1-101 is disposed below the liquid lens element 1-OE1 and the fixing member 1-OE2. The bottom of the fixing member 1-OE2 can be a thin film, so the shaping member 1-101 can be used to change the shape of the liquid lens element 1-OE1.

[0789] Figure 4 This indicates that the liquid lens element 1-OE1 is not deformed and the shaping part 1-101 remains in an initial position. The liquid lens element 1-OE1 has an optical axis 1-O. When a driving current is applied to the driving coil of the driving module 1-DM, a magnetic force is generated between the driving coil and the corresponding magnetic element. The driving module 1-DM drives the movable component 1-MA through this magnetic force, so that the movable component 1-MA drives the shaping part 1-101 through the connecting component 1-CA to push the lower side of the liquid lens element 1-OE1, thereby causing the liquid lens element 1-OE1 to deform.

[0790] like Figure 2 as well as Figure 5As shown, when the first drive component 1-DA1 and the third drive component 1-DA3 of the drive module 1-DM provide the same magnitude of thrust 1-F1 and 1-F3, the shaping part 1-101 will translate along the optical axis 1-O. At this time, the lens curvature of the liquid lens element 1-OE1 is compared with... Figure 4 The curvature of the liquid lens element 1-OE1 changes, that is, the shape of the liquid lens element 1-OE1 is altered. This changes the optical properties of the liquid lens element 1-OE1, thereby achieving the effect of optical zoom.

[0791] Similarly, see Figure 6 When the drive module 1-DM drives the molded part 1-101 to tilt, such as Figure 6 Unequal thrusts 1-F1 and 1-F3 are applied to both sides of the liquid lens element 1-OE1 by the molding part 1-101, causing the optical axis 1-O of the liquid lens element 1-OE1 to rotate and deviate from the main axis 1-AX, that is, there is an included angle 1-θ1 between the two, which changes the optical properties of the liquid lens element 1-OE1, thereby achieving the effects of optical zoom, focusing or optical image stabilization.

[0792] Next, please refer to Figure 2 and Figure 7 , Figure 7 This is a schematic diagram of a portion of the structure of an optical system 1-100 according to an embodiment of the present disclosure. In this embodiment, the first movable member 1-1081 of the movable component 1-MA has a first movable member surface 1-1081S, and the third movable member 1-1083 has a third movable member surface 1-1083S. The first movable member surface 1-1081S faces the first driving component 1-DA1, while the third movable member surface 1-1083S faces the third driving component 1-DA3.

[0793] Please continue to refer to this. Figure 8 , Figure 8 This is a schematic diagram of a partial structure of an optical system 1-100 according to an embodiment of the present disclosure. The optical system 1-100 may define an imaginary plane 1-HP perpendicular to the main axis 1-AX. When the drive module 1-DM drives the movable component 1-MA to move and is viewed along a direction perpendicular to the main axis 1-AX, the angle 1-A1 between the movable component surface 1-103S and the imaginary plane 1-HP is less than or equal to the angle 1-A2 between the line 1-LN connecting the centers of the first movable component surface 1-1081S and the third movable component surface 1-1083S and the imaginary plane 1-HP.

[0794] Please refer to Figure 2 as well as Figure 9 , Figure 9This is a perspective view of a first connector 1-1051 and a movable element 1-103 according to an embodiment of the present disclosure. The movable component 1-MA is connected to the movable element 1-103 by four connectors. For example, the first movable member 1-1081 is connected to the movable element 1-103 via an elastic portion 1-105F of the first connector 1-1051.

[0795] like Figure 2 and Figure 9 As shown, the elastic part 1-105F may have a plate-like structure, generally parallel to the main axis 1-AX. Furthermore, the first connector 1-1051 has a platform surface 1-105T facing the movable element 1-103. Additionally, the optical system 1-100 may also include an adhesive 1-AD disposed between the platform surface 1-105T and the movable element 1-103. The adhesive 1-AD may be made of glue or solder.

[0796] Please refer to Figure 10 , Figure 10 This is a schematic diagram of a first connector 1-1051 and a first movable member 1-1081 according to an embodiment of the present disclosure. Figure 10 As shown, the first active member 1-1081 of the active assembly 1-MA may have a first receiving groove 1-AS1, and the first receiving groove 1-AS1 is configured to receive the first connector 1-1051.

[0797] Additionally, the first movable member 1-1081 may also include a second receiving groove 1-AS2, and a bonding element AE may be disposed in the second receiving groove 1-AS2, configured to bond the first connector 1-1051, so that the first connector 1-1051 is fixedly disposed on the first movable member 1-1081.

[0798] Please refer to Figures 11 to 13 , Figure 11 An exploded view of an optical system 1-100A according to another embodiment of this disclosure. Figure 11A This is a top view of a portion of the structure of an optical system 1-100A according to another embodiment of the present disclosure. Figure 12 This is a perspective cross-sectional view of an optical system 1-100A according to another embodiment of the present disclosure, and Figure 13 This is a bottom view of a partial structure of an optical system 1-100A according to another embodiment of the present disclosure. The optical system 1-100A is similar to the optical system 1-100, and in this embodiment, the connecting assembly 1-CA of the optical system 1-100A also includes four connectors.

[0799] Each connector may have an elastic part and a rigid part. For example... Figure 11 , Figure 11A and Figure 12As shown, the second connector 1-1052 has an elastic portion 1-1055 and a rigid portion 1-1056. The elastic portion 1-1055 may have a plate-like structure, not parallel to the main shaft 1-AX, for example, perpendicular to the main shaft 1-AX, and the rigid portion 1-1056 is connected to the elastic portion 1-1055 by an adhesive member 1-AD. The rigid portion 1-1056 is connected between the elastic portion 1-1055 and the second movable member 1-1082 of the movable assembly 1-MA, and in the direction of the main shaft 1-AX (Z-axis direction), the elastic coefficient of the rigid portion 1-1056 is greater than the elastic coefficient of the elastic portion 1-1055. That is, in the Z-axis direction, the second connector 1-1052 is relatively stiff, while in the X-axis or Y-axis direction it is relatively soft (elastic).

[0800] Furthermore, such as Figure 12 As shown, the optical system 1-100A also includes a lens barrel 1-LB configured to house at least one second optical element 1-LS, the second optical element 1-LS being a solid-state lens. The lens barrel 1-LB has four protrusions 1-LBP extending toward the movable element 1-103.

[0801] In this embodiment, the elastic portions of these connectors in the connecting assembly 1-CA are arranged around the main shaft 1-AX. Specifically, as Figure 11A As shown, the elastic portion 1-1055 of the first connector 1-1051 to the fourth connector 1-1054 is arranged around the main shaft 1-AX. Additionally, as... Figure 11A as well as Figure 12 As shown, when viewed along the direction of the main axis 1-AX, the bump 1-LBP is located between two adjacent elastic parts 1-1055.

[0802] Next, please continue to refer to Figure 11A and Figure 13 ( Figure 13 (The lens barrel 1-LB and the second optical element 1-LS are not shown). The elastic part 1-1055 may include a first cantilever 1-1057, a second cantilever 1-1058, and a contact part 1-1059. The first cantilever 1-1057 and the second cantilever 1-1058 are symmetrically arranged (for example, the first cantilever 1-1057 and the second cantilever 1-1058 of the fourth connector 1-1054 are symmetrical with respect to the X-axis), and the contact part 1-1059 is fixedly disposed at the bottom of the movable element 1-103.

[0803] In this embodiment, when viewed along the direction of the main axis 1-AX, the movable element 1-103 does not overlap with at least a portion of the first cantilever 1-1057. For example... Figure 13As shown, the first cantilever 1-1057 and the second cantilever 1-1058 overlap with the movable element 1-103 only partially. It should be noted that in other embodiments, the first cantilever 1-1057 and the second cantilever 1-1058 may not overlap with the movable element 1-103 at all.

[0804] In addition, such as Figure 13 As shown, the movable element 1-103 may have an opening 1-1031 and four through holes 1-1033. The spindle 1-AX passes through the opening 1-1031, and the through holes 1-1033 are adjacent to the opening 1-1031. Specifically, the through holes 1-1033 are configured symmetrically around the opening 1-1031. Based on the design of the through holes 1-1033, during assembly operations, the operator can retrieve the movable element 1-103 through the through holes 1-1033 without touching the central opening 1-1031, thus avoiding damage to the opening 1-1031.

[0805] Please refer to Figure 12 as well as Figure 14 , Figure 14 This is a partial structural schematic diagram of the movable component 1-MA according to another embodiment of the present disclosure. In this embodiment, a portion of the rigid part 1-1056 is embedded in the first movable member 1-1081. The rigid part 1-1056 may include a first segment 1-SG1 and a second segment 1-SG2 connected to the first segment 1-SG1, and the second segment 1-SG2 is not parallel to the first segment 1-SG1. For example, the first segment 1-SG1 is perpendicular to the second segment 1-SG2.

[0806] Please refer to Figure 15 , Figure 15 This is a top view of a portion of the structure of an optical system 1-100A according to another embodiment of the present disclosure. In this embodiment, when viewed along the main axis 1-AX, the movable component 1-MA overlaps with the first optical element 1-OE, making the first optical element 1-OE larger and thus possessing better optical characteristics, such as a greater light intake. In other embodiments, the movable component 1-MA may not overlap with the first optical element 1-OE. Since the first optical element 1-OE is smaller, a lightweight effect can be achieved.

[0807] This disclosure provides an optical system comprising a first optical element 1-OE, a shaping member 1-101, a movable element 1-103, a fixed assembly 1-FA, a connecting assembly 1-CA, a movable assembly 1-MA, and a drive module 1-DM. The movable element 1-103 is configured to be connected to the first optical element 1-OE via the shaping member 1-101, and the movable assembly 1-MA is connected to the movable element 1-103 via the connecting assembly 1-CA. When the drive module 1-DM is configured to drive the movable assembly 1-MA to move relative to the fixed assembly 1-FA, it can move the movable element 1-103, causing the shaping member 1-101 to press against the bottom of the first optical element 1-OE, thereby changing the optical properties of the liquid lens element 1-OE1.

[0808] Furthermore, each movable component in the movable assembly 1-MA can move independently or collectively, thereby altering the optical properties of the liquid lens element 1-OE1 according to different needs. This enables functions such as optical zoom, optical focus, or optical shake compensation, and improves the performance of the drive mechanism.

[0809] Second set of embodiments.

[0810] Please refer to Figures 16 to 18 , Figure 16 This is a perspective view of an optical system 2-100 according to an embodiment of the present disclosure. Figure 17 This is an exploded view of an optical system 2-100 according to an embodiment of the present disclosure, and Figure 18 According to an embodiment of the present disclosure Figure 16 The optical system 2-100 is shown in cross-sectional view along line segment 2-A-2-A'. The optical system 2-100 can be an optical imaging system configured to carry and drive a first optical element 2-OE, which defines an optical axis 2-O. The optical system 2-100 can be installed in various electronic devices or portable electronic devices, such as smartphones, for users to perform image extraction functions. In this embodiment, the optical system 2-100 can be a voice coil motor (VCM) with autofocus (AF) functionality, but this disclosure is not limited thereto. In other embodiments, the optical system 2-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.

[0811] like Figure 17As shown, in this embodiment, the optical system 2-100 may include a fixed component 2-FA, a shaping component 2-101, a movable element 2-103, a connecting component 2-CA, a movable component 2-MA, and a driving module 2-DM. The shaping component 2-101 is connected between the movable element 2-103 and the first optical element 2-OE. The movable element 2-103 is movable relative to the fixed component 2-FA, and the driving module 2-DM is configured to drive the movable element 2-103 to move relative to the fixed component 2-FA. Specifically, the movable component 2-MA is movably connected to the movable element 2-103 via the connecting component 2-CA, and the driving module 2-DM drives the movable component 2-MA to move relative to the fixed component 2-FA, thereby driving the movable element 2-103.

[0812] In this embodiment, as Figure 17 as well as Figure 18 As shown, the fixing assembly 2-FA includes a housing 102, a frame 2-104, and a base 2-112. The housing 2-102 is fixedly connected to the base 2-112, and the frame 2-104 is also fixedly connected to the inner wall surface of the housing 2-102. The fixing assembly 2-FA may define a main axis 2-AX, which is parallel to or overlaps with the optical axis 2-O of the first optical element 2-OE when the optical system 2-100 is not activated. In addition, the movable element 2-103 has a movable element surface 2-103S facing the first optical element 2-OE.

[0813] like Figure 17 as well as Figure 18 As shown, the aforementioned housing 2-102 has a hollow structure with a housing opening 2-1021 formed thereon, and a base opening 2-1121 is formed on the base 2-112. The center of the housing opening 2-1021 corresponds to the optical axis 2-O of the first optical element 2-OE, and the base opening 2-1121 corresponds to the photosensitive element (not shown) disposed below the base 2-112. In this embodiment, the first optical element 2-OE is fixedly disposed within the housing opening 2-1021. External light can enter the housing 2-102 through the first optical element 2-OE and pass through the base opening 2-1121 before being received by the aforementioned photosensitive element to generate a digital image signal.

[0814] Furthermore, the housing 2-102 is disposed on the base 2-112 and may have an accommodating space 2-1023 configured to accommodate the movable element 2-103, the frame 2-104, the movable component 2-MA, the connecting component 2-CA, and the drive module 2-DM.

[0815] like Figure 17 and Figure 18As shown, in this embodiment, the movable component 2-MA may include four movable members (first movable member 2-1081, second movable member 2-1082, third movable member 2-1083, and fourth movable member 2-1084), and the connecting component 2-CA may include four connectors (first connector 2-1051, second connector 2-1052, third connector 2-1053, and fourth connector 2-1054). The first movable member 2-1081 to the fourth movable member 2-1084 are respectively connected to the movable element 2-103 through the first connector 2-1051 to the fourth connector 2-1054.

[0816] Additionally, the optical system 2-100 may further include a first elastic element 2-106 and a second elastic element 2-110, and the base 2-112 may include four protrusions 2-1123. The outer portion (outer ring portion) of the first elastic element 2-106 is fixedly disposed on the top surface of the protrusion 2-1123, the outer portion (outer ring portion) of the second elastic element 2-110 is fixedly disposed on a plane 2-1125 of the protrusion 2-1123, and the inner portions (inner ring portions) of the first elastic element 2-106 and the second elastic element 2-110 are respectively connected to the upper and lower sides of the movable component 2-MA, so that the first movable component 2-1081 to the fourth movable component 2-1084 are suspended in the accommodating space 2-1023.

[0817] In this embodiment, the drive module 2-DM may include four drive components (first drive component 2-DA1, second drive component 2-DA2, third drive component 2-DA3, and fourth drive component 2-DA4). The first drive component 2-DA1 includes a first drive coil 2-CL1 and a first magnetic element 2-MG1, the second drive component 2-DA2 includes a second drive coil 2-CL2 and a second magnetic element 2-MG2, the third drive component 2-DA3 includes a third drive coil 2-CL3 and a third magnetic element 2-MG3, and the fourth drive component 2-DA4 includes a fourth drive coil 2-CL4 and a fourth magnetic element 2-MG4.

[0818] In this embodiment, each magnetic element has a magnetic surface. For example, such as Figure 17 As shown, the first magnetic element 2-MG1 and the second magnetic element 2-MG2 each have a first magnetic surface 2-MS1 and a second magnetic surface 2-MS2. The first magnetic surface 2-MS1 faces the first driving coil 2-CL1, and the second magnetic surface 2-MS2 faces the second driving coil 2-CL2. The first magnetic surface 2-MS1 and the second magnetic surface 2-MS2 face different directions.

[0819] In this embodiment, as Figure 17 As shown, the frame 2-104 has multiple grooves 2-1041 and a central opening 2-1043. In this embodiment, the frame 2-104 has four grooves 2-1041 configured to accommodate the aforementioned four magnetic elements, but the number of grooves 2-1041 and magnetic elements is not limited to this embodiment. The central opening 2-1043 is configured to accommodate the first drive coil 2-CL1 to the fourth drive coil 2-CL4 and the first movable member 2-1081 to the fourth movable member 2-1084.

[0820] In this embodiment, the first driving coil 2-CL1 to the fourth driving coil 2-CL4 can be wound coils, respectively disposed on the first movable member 2-1081 to the fourth movable member 2-1084. When the first driving coil 2-CL1 to the fourth driving coil 2-CL4 are energized, they can generate electromagnetic driving force with the first magnetic element 2-MG1 to the fourth magnetic element 2-MG4 respectively, thereby driving the first movable member.

[0821] At least one of the four movable components 2-1081 to 2-1084 moves relative to the base 2-112 and the frame 2-104 along the direction of the optical axis 2-O (Z-axis direction) to perform autofocusing or optical image stabilization.

[0822] The drive components of the drive module 2-DM can operate individually or together. For example, the first drive component 2-DA1 is configured to drive the first movable member 2-1081 to move relative to the fixed component 2-FA, and the second drive component 2-DA2 is configured to drive the second movable member 2-1082 to move relative to the fixed component 2-FA and the first movable member 2-1081, and so on.

[0823] Furthermore, such as Figure 17 As shown, in this embodiment, the fixing component 2-FA may further include at least one circuit component 2-170, configured to be electrically connected to the drive module 2-DM via a first elastic element 2-106 or a second elastic element 2-110. The circuit component 2-170 may be implemented by insert molding, but is not limited thereto. Furthermore, the circuit component 2-170, the first elastic element 2-106, and the second elastic element 2-110 may constitute a circuit assembly.

[0824] Next, please refer to Figures 19 to 21 , Figure 19 This is a schematic diagram showing the first optical element 2-OE according to an embodiment of the present disclosure not being pushed by the molding part 2-101. Figure 20 as well as Figure 21 This is a schematic diagram showing the first optical element 2-OE after being pushed by the molding part 2-101 according to an embodiment of the present disclosure. Figure 19 As shown, the first optical element 2-OE can be a liquid lens, comprising a liquid lens element 2-OE1 and a fixing member 2-OE2. The liquid lens element 2-OE1 is disposed within the fixing member 2-OE2, which has a hollow structure. The fixing member 2-OE2 has the function of protecting and supporting the liquid lens element 2-OE1. The shaping member 2-101 is disposed below the liquid lens element 2-OE1 and the fixing member 2-OE2. The bottom of the fixing member 2-OE2 can be a thin film, so the shaping member 2-101 can be used to change the shape of the liquid lens element 2-OE1.

[0825] Figure 19 This indicates that the liquid lens element 2-OE1 is not deformed and the shaping part 2-101 remains in an initial position. The liquid lens element 2-OE1 has an optical axis 2-O. When a driving current is applied to the driving coil of the driving module 2-DM, a magnetic force is generated between the driving coil and the corresponding magnetic element. The driving module 2-DM drives the movable component 2-MA through this magnetic force, so that the movable component 2-MA drives the shaping part 2-101 through the connecting component 2-CA to push the lower side of the liquid lens element 2-OE1, thereby causing the liquid lens element 2-OE1 to deform.

[0826] like Figure 17 as well as Figure 20 As shown, when the first drive component 2-DA1 and the third drive component 2-DA3 of the drive module 2-DM provide the same magnitude of thrust 2-F1 and 2-F3, the molding part 2-101 will translate along the optical axis 2-O. At this time, the lens curvature coefficient of the liquid lens element 2-OE1 is compared with... Figure 19 The curvature of the liquid lens element 2-OE1 changes, that is, the shape of the liquid lens element 2-OE1 is altered. This changes the optical properties of the liquid lens element 2-OE1, thereby achieving the effect of optical zoom.

[0827] Similarly, see Figure 21 When the drive module 2-DM drives the molded part 2-101 to tilt, such as Figure 21 Unequal thrusts 2-F1 and 2-F3 are applied to both sides of the liquid lens element 2-OE1 by the molding part 2-101, causing the liquid lens element 2-OE1 to rotate and deviate from the main axis 2-AX, that is, there is an included angle 2-θ1 between the two, which changes the optical properties of the liquid lens element 2-OE1, thereby achieving the effects of optical zoom, focusing or optical image stabilization.

[0828] Next, please refer to Figure 22 , Figure 22 This is a perspective view of a portion of the structure of an optical system 2-100A according to another embodiment of the present disclosure. In this embodiment, the first elastic element 2-106 may include four conductive elements 2-1061 to 2-1064, and the second elastic element 2-110 may include four conductive elements 2-1101 to 2-1104.

[0829] like Figure 22 As shown, the first driving coil 2-CL1 of the first driving component 2-DA1 is electrically connected to the second driving coil 2-CL2 of the second driving component 2-DA2 via the conductive element 2-1061 (a first conductive element) of the circuit component. Specifically, the conductive element 2-1061 (the first conductive element) has a first string arm 2-SA1 and a second string arm 2-SA2, which are respectively connected to the first driving coil 2-CL1 of the first driving component 2-DA1 and the second driving coil 2-CL2 of the second driving component 2-DA2.

[0830] In addition, the protrusion 2-1123 of the base 2-112 is located between the first drive coil 2-CL1 and the second drive coil 2-CL2, and the conductive element 2-1061 (the first conductive element) is connected to this protrusion 2-1123, for example, by using glue or solder to fix it to the protrusion 2-1123.

[0831] like Figure 22 As shown, the first driving coil 2-CL1 of the first driving component 2-DA1 can also be electrically connected to the second driving coil 2-CL2 of the second driving component 2-DA2 via the conductive element 2-1101 (second conductive element). The conductive element 2-1061 (first conductive element) and the conductive element 2-1101 (second conductive element) are respectively disposed on both sides of the first driving component 2-DA1 and the second driving component 2-DA2, for example, disposed on the upper and lower sides of the first driving component 2-DA1 and the second driving component 2-DA2 along the Z-axis direction.

[0832] Furthermore, the first movable member 2-1081 of the movable component 2-MA is movably connected to the protrusion 2-1123 of the fixed component 2-FA via the aforementioned first and second conductive elements, but is not limited thereto. In other embodiments of this disclosure, the movable component 2-MA may also be movably connected to the protrusion 2-1123 of the fixed component 2-FA only via the aforementioned first conductive element.

[0833] Similarly, the second drive coil 2-CL2 of the second drive assembly 2-DA2 can be electrically connected to the third drive coil 2-CL3 of the third drive assembly 2-DA3 via the conductive element 2-1062 (third conductive element), and the second drive coil 2-CL2 of the second drive assembly 2-DA2 can also be electrically connected to the third drive coil 2-CL3 of the third drive assembly 2-DA3 via the conductive element 2-1102 (fourth conductive element), wherein the aforementioned third and fourth conductive elements are respectively disposed on the upper and lower sides (along the Z-axis direction) of the second drive assembly 2-DA2 and the third drive assembly 2-DA3.

[0834] Please continue to refer to this. Figure 22 and Figure 23 , Figure 23 This is a schematic diagram of a partial structure of an optical system 2-100A according to another embodiment of the present disclosure. The aforementioned conductive elements (e.g., the first and third conductive elements) each have a plate-like structure, and when viewed along the extending direction of conductive element 2-1061 (e.g., the Y-axis direction), conductive element 2-1061 (the first conductive element) and conductive element 2-1062 (the third conductive element) at least partially overlap. In this embodiment, conductive element 2-1061 (the first conductive element) and conductive element 2-1062 (the third conductive element) overlap.

[0835] Please refer to Figure 24 , Figure 24 This is an enlarged schematic diagram of a portion of the structure of an optical system 2-100A according to another embodiment of the present disclosure. Conductive element 2-1061 (first conductive element) and conductive element 2-1062 (third conductive element) are disposed on a top surface 2-108T of the second movable member 2-1082 of the movable assembly 2-MA, and when viewed along the direction of the principal axis 2-AX (Z-axis direction), conductive element 2-1061 (first conductive element) and conductive element 2-1062 (third conductive element) do not overlap.

[0836] Furthermore, in this embodiment, the optical system 2-100A may further include an insulating member 2-IE, disposed between the conductive element 2-1061 (first conductive element) and the conductive element 2-1062 (third conductive element). In this embodiment, the insulating member 2-IE may be an adhesive, configured to connect the conductive element 2-1061 (first conductive element), the conductive element 2-1062 (third conductive element), and the second movable member 2-1082 of the movable assembly 2-MA, such as... Figure 24As shown. The insulating member 2-IE can be used to fix the ends of the conductive element 2-1061 (first conductive element) and the conductive element 2-1062 (third conductive element) to the second movable member 2-1082, and can make the conductive element 2-1061 (first conductive element) electrically independent of the conductive element 2-1062 (third conductive element).

[0837] Please refer to Figure 25 , Figure 25 This is an enlarged schematic diagram of a portion of the structure of an optical system 2-100A according to another embodiment of the present disclosure, viewed from another perspective. The optical system 2-100A is similar to the optical system 2-100, except that each connector in the optical system 2-100A may have an elastic portion and a rigid portion. For example, the first connector 2-1051 may have an elastic portion 2-1055 and a rigid portion 2-1056, and the rigid portion 2-1056 is connected to the elastic portion 2-1055 by an adhesive member 2-AD. The rigid portion 2-1056 is connected between the elastic portion 2-1055 and the first movable member 2-1081.

[0838] Furthermore, such as Figure 25 As shown, the conductive element 2-1061 (first conductive element) has an electrical contact 2-EC and a narrow portion 2-NP. The electrical contact 2-EC is an electrical contact 2-EC1 configured to be electrically connected to the first drive coil 2-CL1 of the first drive assembly 2-DA1, for example, by soldering. The narrow portion 2-NP is adjacent to the electrical contact 2-EC, and the design of the narrow portion 2-NP can reduce the heat transfer during soldering to avoid damage to the first moving member 2-1081, and can concentrate the heat energy on the electrical contact 2-EC, thereby more reliably melting the solder and allowing the solder to be set more securely.

[0839] Please refer to Figure 26 , Figure 26 This is an enlarged schematic diagram of the optical system 2-100A after removing the base 2-112 according to an embodiment of the present disclosure. In this embodiment, conductive element 2-1061 (first conductive element) and conductive element 2-1101 (second conductive element) can be electrically connected to the external electrical connection portion 2-TEP via circuit components 2-170 embedded in the base 2-112, for example by soldering.

[0840] Specifically, such as Figure 26As shown, conductive element 2-1061 (the first conductive element) is electrically connected to circuit component 2-170 through a first electrical connection point 2-EP1, and conductive element 2-1101 (the second conductive element) is electrically connected to circuit component 2-170 through a second electrical connection point 2-EP2. Furthermore, the shortest distance between the first electrical connection point 2-EP1 and the first optical element 2-OE is different from the shortest distance between the second electrical connection point 2-EP2 and the first optical element 2-OE. That is, along the direction of the main axis 2-AX, the distance between the first electrical connection point 2-EP1 and the first optical element 2-OE is less than the distance between the second electrical connection point 2-EP2 and the first optical element 2-OE.

[0841] Next, please Figure 27 , Figure 27 This is a bottom schematic diagram of the removal base 2-112 of the optical system 2-100A according to another embodiment of the present disclosure. When viewed along the direction of the main axis 2-AX, the second drive assembly 2-DA2 overlaps with the external electrical connection portion 2-TEP, and the first drive assembly 2-DA1 does not overlap with the external electrical connection portion 2-TEP. The external electrical connection portion 2-TEP is a pin exposed on the base 2-112.

[0842] In this embodiment, circuit components 2-170 can form a polygonal structure, for example... Figure 27 The rectangular structure is as follows. Furthermore, conductive element 2-1062 (the third conductive element) is electrically connected to circuit component 2-170 through a third electrical connection point 2-EP3, and conductive element 2-1102 (the fourth conductive element) is electrically connected to circuit component 2-170 through a fourth electrical connection point 2-EP4. The aforementioned second electrical connection point 2-EP2 and fourth electrical connection point 2-EP4 are located on one side of circuit component 2-170, for example, on the left side.

[0843] It is worth noting that when viewed along the direction of the main axis 2-AX, the aforementioned second electrical connection point 2-EP2 and fourth electrical connection point 2-EP4 are located between the aforementioned first electrical connection point 2-EP1 and third electrical connection point 2-EP3.

[0844] Please refer to Figure 28 , Figure 28 This is a partial three-dimensional schematic diagram of an optical system according to another embodiment of the present disclosure. In this embodiment, each driving component may further include a flexible circuit board. For example, the first driving component 2-DA1 to the fourth driving component 2-DA4 may each have a circuit board 2-1141 to a circuit board 2-1144, and each circuit board may have six electrical contacts 2-EC1 to 2-EC6.

[0845] In this embodiment, electrical contacts 2-EC1 and 2-EC2 of circuit board 2-1141 are electrically connected to a positive voltage and a negative voltage, respectively; electrical contacts 2-EC3 and 2-EC4 of circuit board 2-1141 are electrically connected to a data signal and a clock signal, respectively; and electrical contacts 2-EC5 and 2-EC6 of circuit board 2-1141 output a first output signal and a second output signal, respectively.

[0846] Since circuit boards 2-1141 and 2-1142 share conductive elements 2-1061 and 2-1101, electrical contact 2-EC2 of circuit board 2-1142 is electrically connected to a positive voltage, while electrical contact 2-EC4 of circuit board 2-1142 is electrically connected to a data signal. Similarly, since circuit boards 2-1142 and 2-1143 share conductive elements 2-1062 and 2-1102, electrical contact 2-EC1 of circuit board 2-1142 is electrically connected to a negative voltage, while electrical contact 2-EC3 of circuit board 2-1142 is electrically connected to a clock signal, and electrical contacts 2-EC5 and 2-EC6 of circuit board 2-1142 respectively output a second output signal and a first output signal.

[0847] This means that the circuit layout of circuit board 2-1141 (the first circuit element) is different from that of circuit board 2-1142 (the second circuit element). For example, the circuit layouts of circuit board 2-1141 and circuit board 2-1142 are symmetrically arranged.

[0848] This disclosure provides an optical system comprising a first optical element 2-OE, a shaping member 2-101, a movable element 2-103, a fixed assembly 2-FA, a connecting assembly 2-2-CA, a movable assembly 2-MA, and a drive module 2-DM. The movable element 2-103 is configured to be connected to the first optical element 2-OE via the shaping member 2-101, and the movable assembly 2-MA is connected to the movable element 2-103 via the connecting assembly 2-CA. When the drive module 2-DM is configured to drive the movable assembly 2-MA to move relative to the fixed assembly 2-FA, it can move the movable element 2-103, causing the shaping member 2-101 to press against the bottom of the first optical element 2-OE, thereby changing the optical properties of the liquid lens element 2-OE1.

[0849] In addition, the circuit layout of adjacent circuit boards in the drive assembly is symmetrical, and adjacent active components in the active assembly 2-MA can share conductive elements, which enables the optical system of this disclosure to achieve the purpose of simplifying mechanism design and miniaturization.

[0850] Third set of embodiments.

[0851] Please refer to the following: Figure 22 , Figure 28 , Figure 29 ,in Figure 29 express Figure 28 A schematic diagram of the circuit boards 2-1141 to 2-1144 in the four drive components 2-DA1 to 2-DA4, where the eight conductive elements 2-1061 to 2-1064 and 2-1101 to 2-1104 are electrically connected.

[0852] like Figure 22 , Figure 28 , Figure 29 As shown, the aforementioned eight conductive elements 2-1061 to 2-1064 and 2-1101 to 2-1104 are, for example, elastic metal springs, used to electrically connect circuit boards 2-1141 to 2-1144 in the four drive assemblies 2-DA1 to 2-DA4. Specifically, the aforementioned conductive elements 2-1061 and 2-1101 are electrically connected to circuit boards 2-1141 and 2-1142; the aforementioned conductive elements 2-1062 and 2-1102 are electrically connected to circuit boards 2-1142 and 2-1143; the aforementioned conductive elements 2-1063 and 2-1103 are electrically connected to circuit boards 2-1143 and 2-1144; and the aforementioned conductive elements 2-1064 and 2-1104 are electrically connected to circuit boards 2-1144 and 2-1141. It should be understood that the aforementioned conductive elements 2-1061 to 2-1064 and 2-1101 to 2-1104 can be connected to an external circuit through the external electrical connection portion 2-TEP exposed on the base 2-112.

[0853] It should be noted that the aforementioned circuit boards 2-1141 to 2-1144 are respectively fixed on four movable components 2-1081 to 2-1084. Furthermore, control circuit elements 2-C1 to 2-C4 (such as...) can be respectively provided on the aforementioned circuit boards 2-1141 to 2-1144. Figure 29 (As shown). Furthermore, the aforementioned movable components 2-1081 to 2-1084 are spaced apart from each other in the horizontal direction, wherein the aforementioned horizontal direction is approximately parallel to the XY plane and forms an angle with the main axis 2-AX, and each movable component can move relative to the fixed component 2-FA and other movable components.

[0854] In this embodiment, the control circuit element 2-C1 (first control circuit element) disposed on the circuit board 2-1141 can transmit a first drive signal to the drive assembly 2-DA1 during a first period to drive the movable member 2-1081 to move relative to the fixed assembly 2-FA along the main shaft 2-AX direction, wherein the aforementioned conductive element 2-1061 is electrically connected to the aforementioned control circuit element 2-C1 through the circuit board 2-1141.

[0855] Similarly, the control circuit element 2-C2 (second control circuit element) disposed on the circuit board 2-1142 can transmit a second drive signal to the drive assembly 2-DA2 during a second period to drive the movable member 2-1082 to move relative to the fixed assembly 2-FA along the main shaft 2-AX direction, wherein the aforementioned conductive element 2-1062 is electrically connected to the aforementioned control circuit element 2-C2 through the circuit board 2-1142.

[0856] Similarly, the control circuit element 2-C3 (third control circuit element) disposed on the circuit board 2-1143 can transmit a third drive signal to the drive assembly 2-DA3 during a third period to drive the movable member 2-1083 to move relative to the fixed assembly 2-FA along the main shaft 2-AX direction, wherein the aforementioned conductive element 2-1063 is electrically connected to the aforementioned control circuit element 2-C3 through the circuit board 2-1143.

[0857] Similarly, the control circuit element 2-C4 (fourth control circuit element) disposed on the circuit board 2-1144 can transmit a fourth drive signal to the drive assembly 2-DA4 during a fourth period to drive the movable member 2-1084 to move relative to the fixed assembly 2-FA along the main shaft 2-AX direction, wherein the aforementioned conductive element 2-1064 is electrically connected to the aforementioned control circuit element 2-C4 through the circuit board 2-1144. For example, the aforementioned control circuit elements 2-C1 to 2-C4 may include a microcontroller unit (MCU), a Hall effect sensor, or other integrated circuit elements.

[0858] from Figure 22 , Figure 28 , Figure 29 As can be seen from the diagram, the optical system of this embodiment is roughly rectangular in shape, with drive components 2-DA1 and 2-DA3 located on two opposite sides of the optical system, and drive components 2-DA2 and 2-DA4 located on the other two opposite sides of the optical system. Furthermore, drive components 2-DA1 and 2-DA2 are located on two adjacent sides of the optical system, drive components 2-DA2 and 2-DA3 are located on two adjacent sides of the optical system, drive components 2-DA3 and 2-DA4 are located on two adjacent sides of the optical system, and drive components 2-DA4 and 2-DA1 are located on two adjacent sides of the optical system.

[0859] It should be noted that, although the external circuit can apply current signals to the four drive components 2-DA1 to 2-DA4 through conductive elements 2-1061 to 2-1064 and 2-1101 to 2-1104 to drive the moving parts,

[0860] 2-1081 to 2-1084 move relative to the fixed component 2-FA. However, since the adjacent drive components 2-DA1 and 2-DA2 share conductive elements 2-1061 and 2-1101, it is impossible to simultaneously drive 2-1081 and 2-1082 using drive components 2-DA1 and 2-DA2. Similarly, adjacent drive components 2-DA2 and 2-DA3 cannot simultaneously drive 2-1082 and 2-1083, adjacent drive components 2-DA3 and 2-DA4 cannot simultaneously drive 2-1083 and 2-1084, and adjacent drive components 2-DA3 and 2-DA4 also cannot simultaneously drive 2-1083 and 2-1084.

[0861] Please refer to the following: Figure 29 , Figure 30 ,in Figure 30 This is a sequence diagram showing how the four driving components 2-DA1 to 2-DA4 sequentially drive the moving components 2-1081 to 2-1084 relative to the fixed component 2-FA during different periods 3-T1 to 3-T4. Figure 30 As shown, in order to overcome the problem of adjacent driving components sharing conductive elements in the aforementioned optical system, this embodiment sequentially drives the four driving components 2-DA1 to 2-DA4 to move the movable components 2-1081 to 2-1084 relative to the fixed component 2-FA during a first period 3-T1, a second period 3-T2, a third period 3-T3, and a fourth period 3-T4. That is, the external circuit can apply current signals to different driving components at different periods through the same conductive element to drive the movable component 2-MA, the movable element 2-103, and the shaping part 2-101 to move, thereby effectively adjusting the optical axis 2-O direction of the liquid lens element 2-OE1.

[0862] Please refer to the following as well. Figure 29 , Figure 31 ,in Figure 31 This is a timing diagram showing that drive components 2-DA1 and 2-DA3 drive movable components 2-1081 and 2-1083 relative to the fixed component 2-FA within the same period, and drive components 2-DA2 and 2-DA4 drive movable components 2-1082 and 2-1084 relative to the fixed component 2-FA within the same period. Figure 29As shown, since the aforementioned drive components 2-DA1 and 2-DA3 do not share the same conductive element connected to the external circuit, and the aforementioned drive components 2-DA2 and 2-DA4 also do not share the same conductive element connected to the external circuit, drive components 2-DA1 and 2-DA3 can respectively drive movable components 2-1081 and 2-1083 to move relative to the fixed component 2-FA within the same period, and drive components 2-DA2 and 2-DA4 can also respectively drive movable components 2-1082 and 2-1084 to move relative to the fixed component 2-FA within the same period. That is to say, in Figure 31 The first period 3-T1 can be exactly the same as the third period 3-T3, and the second period 3-T2 can be exactly the same as the fourth period 3-T4. This can significantly shorten the driving time, thereby improving the efficiency of the optical system 2-100 and its driving module 2-DM, and can also help to miniaturize the optical system 2-100 as a whole.

[0863] Please refer to the following: Figure 32 ,in Figure 32 This is a timing diagram showing how four driving components 2-DA1 to 2-DA4 sequentially drive movable components 2-1081 to 2-1084 relative to the fixed component 2-FA during different periods 3-T1 to 3-T4. (See diagram for example.) Figure 32 As shown, in another embodiment, the first period 3-T1 and the third period 3-T3 can be partially overlapped, or the second period 3-T2 and the fourth period 3-T4 can be partially overlapped. This can also effectively overcome the problem of adjacent driving components sharing conductive elements in the aforementioned optical system.

[0864] It should be understood that in the optical systems of the foregoing embodiments, since the driving components on adjacent sides share the same conductive elements, when the driving components DA1 and DA3 drive the movable components 2-1081 and 2-1083 to move relative to the fixed component 2-FA, the driving components DA2 and DA4 will not drive the second movable components 2-1082 and 2-1084 to move relative to the fixed component 2-FA; similarly, when the driving components DA2 and DA4 drive the second movable components 2-1082 and 2-1084 to move relative to the fixed component 2-FA, the driving components DA1 and DA3 will also not drive the movable components 2-1081 and 2-1083 to move relative to the fixed component 2-FA.

[0865] Fourth set of embodiments.

[0866] Please refer to the following: Figure 17 , Figure 33 ,in Figure 33 express Figure 17A schematic diagram showing that the four movable components 2-1081 to 2-1084 in the optical system 2-100 can move relative to the fixed component 2-FA within the interval 4-1 to 4-4.

[0867] like Figure 33 As shown, in this embodiment, the movable components 2-1081 to 2-1084 can be driven by the drive components 2-DA1 to 2-DA4 to move relative to the fixed component 2-FA along the main shaft 2-AX direction. The movable component 2-1081 can move in a section 4-1 in the main shaft 2-AX direction, the movable component 2-1082 can move in a section 4-2 in the main shaft 2-AX direction, the movable component 2-1083 can move in a section 4-3 in the main shaft 2-AX direction, and the movable component 2-1084 can move in a section 4-4 in the main shaft 2-AX direction.

[0868] It should be noted that due to assembly tolerances, the aforementioned intervals 4-1 to 4-4 may not be entirely identical (e.g., Figure 33 (As shown), in addition, in order to overcome the positioning control problem caused by the aforementioned assembly tolerance, the optical system 2-100 can be calibrated by the following methods.

[0869] Before assembling the optical element 2-OE onto the movable element 2-103, a first height 4-h1 and a second height 4-h2 can be defined within the aforementioned range 4-1 to 4-4. When the movable element 2-103 is positioned at the first height 4-h1 or the second height 4-h2, the positions of the movable members 2-1081 to 2-1084 will be adjusted so that the main surface of the movable element 2-103 is perpendicular to the main axis 2-AX.

[0870] In one embodiment, an optical instrument can be used to project light (e.g., a laser) onto the main surface of the active element 2-103 (e.g., ...). Figure 38 (As shown), and the angle of the main surface relative to the main axis 2-AX is determined by receiving the light reflected from the main surface. Alternatively, in another embodiment, an external device can be used to measure multiple reference systems of the same specifications as the optical system 2-100 to determine the aforementioned first height 4-h1 and second height 4-h2.

[0871] It should be understood that the area between the aforementioned first height 4-h1 and second height 4-h2 constitutes the operation area 4-R of the movable element 2-103, meaning the range within which the movable element 2-103 can move during operation. Furthermore, although the movable components 2-1081 to 2-1084 in this embodiment can move relative to the fixed component 2-FA within the maximum range of motion (ranges 4-1 to 4-4), the actual driven range 4-R will still be smaller than the aforementioned maximum range of motion. A primary objective of this embodiment is to ensure that when the movable element 2-103 moves within the aforementioned range 4-R, its main surface remains perpendicular to the main shaft 2-AX at all times, thereby preventing the optical element 2-OE from being tilted and thus impairing the overall performance of the optical system 2-100.

[0872] Please refer to the following as well. Figure 34 , Figure 35 ,in Figure 34 This graph shows the relationship between the current and the position of the moving element 2-103 when a current signal is applied to the drive component DA1. Figure 35 Then it means Figure 34 A schematic diagram showing a linear relationship between the current signal and an electrical signal encoding sequence.

[0873] like Figure 34 As shown, assuming that the active element 2-103 is located at the aforementioned first height 4-h1 and its main surface is perpendicular to the main shaft 2-AX, the current applied to the drive component DA1 has a first drive signal value 4-I1, and when the active element 2-103 moves to the aforementioned second height 4-h2 and its main surface is perpendicular to the main shaft 2-AX, the current applied to the drive component DA1 has a second drive signal value 4-I2. At this time, a position-current relationship curve 4-IC1 with a linear relationship can be defined for the drive component DA1.

[0874] In this embodiment, an electrical signal coding sequence can be used as the input command parameter for a control circuit element in the aforementioned optical system 2-100. For example... Figure 35 As shown, the aforementioned electrical signal encoding sequence includes codes 0 to 4095. Let the first drive signal value 4-I1 and the second drive signal value 4-I2 correspond to codes 0 and 4095 in the electrical signal encoding sequence, respectively. Then, the correspondence information between the travel region 4-R and the electrical signal encoding sequence 0 to 4095 can be obtained, which can be used for subsequent input drive commands. Similarly, according to the aforementioned method, a correspondence information between the travel region 4-R and the electrical signal encoding sequence can also be established for each drive component DA2 to DA4.

[0875] On the other hand, the optical system 2-100 in this embodiment is further provided with a plurality of position sensors for detecting the movable components 2-1081 to 2-1084 respectively. Assuming that the movable element 2-103 is located at the aforementioned first height 4-h1 and its main surface is perpendicular to the main axis 2-AX, a sensing element senses the position of the movable component 2-1081 and generates a first sensing signal value. And when the movable element 2-103 moves to the aforementioned second height 4-h2 and its main surface is perpendicular to the main axis 2-AX, the sensing element senses the position of the movable component 2-1081 and generates a second sensing signal value. Then, the first and second sensing signal values ​​can be respectively mapped to codes 0 and 4095 in a position sensing signal encoding sequence. Figure 36 Thus, a linear relationship curve 4-SC1 is established between the position and position sensing signal encoding sequence.

[0876] Since the aforementioned position-current relationship curve 4-IC1 and position-position sensing signal encoding sequence relationship curve 4-SC1 are only ideal curves established by interpolation, and have only been accurately calibrated by optical instruments when the position of the moving element 2-103 is at the first height 4-h1 and the second height 4-h2, in order to further improve the positioning control performance and accuracy within the aforementioned travel region 4-R, additional settings can be made within this travel region 4-R, such as... Figure 37 The multiple sampling locations 4-h3, 4-h4, 4-h5 shown can be at equal or different distances.

[0877] During subsequent calibration steps, the moving components 2-1081 to 2-1084 can be driven by these driving components 2-DA1 to 2-DA4 to move along the main shaft 2-AX direction, so as to push the moving element 2-103 to the sampling positions 4-h3, 4-h4, and 4-h5 in sequence and keep its main surface perpendicular to the main shaft 2-AX.

[0878] Please refer to the following: Figure 39 During the process where movable components 2-1081 to 2-1084 sequentially push movable element 2-103 to the aforementioned sampling positions 4-h3, 4-h4, and 4-h5, ensuring its main surface is perpendicular to the main shaft 2-AX, the drive current values ​​supplied to these drive components 2-DA1 to 2-DA4 can be recorded, establishing a correspondence between the position of movable element 2-103 and the aforementioned drive current values. For example, when movable element 2-103 moves to sampling positions 4-h3, 4-h4, and 4-h5 with its main surface perpendicular to the main shaft 2-AX, assuming the actual current values ​​supplied to drive component 2-DA1 are 4-I3, 4-I4, and 4-I5 respectively, it can be observed that it slightly deviates from the target position. Figure 34The position-current relationship curve 4-IC1 shown is due to assembly tolerances or alignment errors between components.

[0879] Similarly, when the moving element 2-103 moves to sampling positions 4-h3, 4-h4, and 4-h5 and its main surface is perpendicular to the main axis 2-AX, assuming that the sensing element generates corresponding position signal sensing codes 4-S3, 4-S4, and 4-S5 due to sensing the position of the moving component 2-1081, it can be observed that it will also deviate slightly. Figure 36 The position-position sensing signal encoding sequence relationship curve 4-SC1 is shown in the figure.

[0880] As can be understood from the above description, when the active element 2-103 is in one of the sampling positions 4-h3, 4-h4, and 4-h5, the driving current values ​​(or electrical signal codes) supplied to these driving components 2-DA1 to 2-DA4 may be different, and the position signal sensing codes generated by these position sensors by sensing these active components 2-1081 to 2-1084 may also be different. As can be seen from Figures 39 and 40, the sampling positions 4-h3, 4-h4, and 4-h5 have a non-linear relationship with both the driving current value and the position signal sensing code.

[0881] To make the relationship between the position of the moving element 2-103 within the travel region 4-R, the drive current, and the position sensor more accurate, a position-drive current correction curve 4-ICM1 can be established for each drive component using curve fitting. Figure 39 Similarly, curve fitting can be used to establish a correction curve 4-SCM1 for the position of the active element 2-103 relative to the position signal sensing encoding sequence for each position sensor. Figure 40 This is to facilitate precise motion control in the future.

[0882] In one embodiment, the electrical signal can also be re-encoded or linearly compensated according to the aforementioned correction relationship curve 4-ICM1; in addition, a new position signal sensing code can be established or linearly compensated according to the aforementioned correction relationship curve 4-SCM1. After completing the aforementioned steps, the optical element 2-OE can be formally assembled onto the moving element 2-103, and all the aforementioned steps can be repeated to ensure that the main surface of the moving element 2-103 is parallel to the main axis 2-AX.

[0883] In one embodiment, the attitude of the optical system 2-100 can be sensed by an inertial sensor (not shown), and a correction electrical signal can be applied to the aforementioned drive components 2-DA1 to 2-DA4 according to the sensed attitude of the optical system 2-100, so that the main surface of the active element 2-103 can remain perpendicular to the main axis 2-AX.

[0884] In one embodiment, the attitude information of the optical system 2-100 sensed by the aforementioned inertial sensor and its corresponding correction electrical signal can also be stored in a memory unit to improve the efficiency of motion control.

[0885] In one embodiment, current or voltage signals can be applied to these driving components 2-DA1 to 2-DA4 to drive these movable components 2-1081 to 2-1084 to move along the main axis 2-AX, respectively. After completing the aforementioned steps, the movable element 2-103 can be moved to a target position within the travel region 4-R by means of open-loop control or closed-loop control, and the main surface of the movable element 2-103 can be kept perpendicular to the main axis 2-AX to avoid the optical element 2-OE from being tilted and thus damaging the overall performance of the optical system 2-100.

[0886] Fifth set of examples.

[0887] Please refer to Figures 41 to 43 , Figure 41 This is a perspective view of an optical system 5-100 according to an embodiment of the present disclosure. Figure 42 This is an exploded view of an optical system 5-100 according to an embodiment of the present disclosure, and Figure 43 According to an embodiment of the present disclosure Figure 41 The optical system 5-100 is shown in cross-sectional view along line segment 5-A-5-A'. The optical system 5-100 can be an optical imaging system configured to carry and drive a first optical element 5-OE, which defines an optical axis 5-O. The optical system 5-100 can be installed in various electronic devices or portable electronic devices, such as smartphones, for users to perform image extraction functions. In this embodiment, the optical system 5-100 can be a voice coil motor (VCM) with autofocus (AF) functionality, but this disclosure is not limited thereto. In other embodiments, the optical system 5-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.

[0888] like Figure 42As shown, in this embodiment, the optical system 5-100 may include a fixed component 5-FA, a shaping component 5-101, a movable element 5-103, a connecting component 5-CA, a movable component 5-MA, and a driving module 5-DM. The shaping component 5-101 is connected between the movable element 5-103 and the first optical element 5-OE. The movable element 5-103 is movable relative to the fixed component 5-FA, and the driving module 5-DM is configured to drive the movable element 5-103 to move relative to the fixed component 5-FA. Specifically, the movable component 5-MA is movably connected to the movable element 5-103 via the connecting component 5-CA, and the driving module 5-DM drives the movable component 5-MA to move relative to the fixed component 5-FA, thereby driving the movable element 5-103.

[0889] In this embodiment, as Figure 42 as well as Figure 43 As shown, the fixing assembly 5-FA includes a housing 5-102, a frame 5-104, and a base 5-112. The housing 5-102 is fixedly connected to the base 5-112, and the frame 5-104 is also fixedly connected to the inner wall of the housing 5-102. The fixing assembly 5-FA may define a main axis 5-AX, which is parallel to or overlaps with the optical axis 5-O of the first optical element 5-OE when the optical system 5-100 is not activated. In addition, the movable element 5-103 has a movable element surface 5-103S facing the first optical element 5-OE.

[0890] like Figure 42 as well as Figure 43 As shown, the aforementioned housing 5-102 has a hollow structure, and a housing opening 5-1021 is formed thereon. A base opening 5-1121 is formed on the base 5-112. The center of the housing opening 5-1021 corresponds to the optical axis 5-O of the first optical element 5-OE, and the base opening 5-1121 corresponds to a photosensitive element (not shown) disposed below the base 5-112. In this embodiment, the first optical element 5-OE is fixedly disposed within the housing opening 5-1021. External light can enter the housing 5-102 through the first optical element 5-OE and, after passing through the base opening 5-1121, is received by the aforementioned photosensitive element to generate a digital image signal.

[0891] Furthermore, the housing 5-102 is disposed on the base 5-112 and may have an accommodating space 5-1023 configured to accommodate the movable element 5-103, the frame 5-104, the movable component 5-MA, the connecting component 5-CA, and the drive module 5-DM.

[0892] like Figure 42 and Figure 43As shown, in this embodiment, the movable component 5-MA may include four movable members (first movable member 5-1081, second movable member 5-1082, third movable member 5-1083, and fourth movable member 5-1084), and the connecting component 5-CA may include four connectors (first connector 5-1051, second connector 5-1052, third connector 5-1053, and fourth connector 5-1054). The first movable member 5-1081 to the fourth movable member 5-1084 are respectively connected to the movable element 5-103 through the first connector 5-1051 to the fourth connector 5-1054. Specifically, each of the first connecting member 5-1051 to the fourth connecting member 5-1054 may include an elastic portion 5-1055 and a rigid portion 5-1056. The elastic portion 5-1055 is connected to the movable element 5-103, and the rigid portion 5-1056 is connected to the elastic portion 5-1055 via an adhesive member 5-AD. Furthermore, the multiple elastic portions 5-1055 collectively constitute an elastic sheet surrounding the main shaft 5-AX, such as... Figure 42 As shown.

[0893] Additionally, the optical system 5-100 may further include a first elastic element 5-106 and a second elastic element 5-110, and the base 5-112 may include four protrusions 5-1123. The outer portion (outer ring portion) of the first elastic element 5-106 is fixedly disposed on the top surface of the protrusion 5-1123, the outer portion (outer ring portion) of the second elastic element 5-110 is fixedly disposed on a plane 5-1125 of the protrusion 5-1123, and the inner portions (inner ring portions) of the first elastic element 5-106 and the second elastic element 5-110 are respectively connected to the upper and lower sides of the movable component 5-MA, so that the first movable component 5-1081 to the fourth movable component 5-1084 are suspended in the accommodating space 5-1023.

[0894] In this embodiment, the drive module 5-DM may include four drive components (first drive component 5-DA1, second drive component 5-DA2, third drive component 5-DA3, and fourth drive component 5-DA4). The first drive component 5-DA1 includes a first drive coil 5-CL1 and a first magnetic element 5-MG1, the second drive component 5-DA2 includes a second drive coil 5-CL2 and a second magnetic element 5-MG2, the third drive component 5-DA3 includes a third drive coil 5-CL3 and a third magnetic element 5-MG3, and the fourth drive component 5-DA4 includes a fourth drive coil 5-CL4 and a fourth magnetic element 5-MG4.

[0895] In this embodiment, each magnetic element has a magnetic surface. For example, such as Figure 42As shown, the first magnetic element 5-MG1 and the second magnetic element 5-MG2 each have a first magnetic surface 5-MS1 and a second magnetic surface 5-MS2. The first magnetic surface 5-MS1 faces the first driving coil 5-CL1, and the second magnetic surface 5-MS2 faces the second driving coil 5-CL2. The first magnetic surface 5-MS1 and the second magnetic surface 5-MS2 face different directions.

[0896] In this embodiment, as Figure 42 As shown, the frame 5-104 has multiple grooves 5-1041 and a central opening 5-1043. In this embodiment, the frame 5-104 has four grooves 5-1041 configured to accommodate the aforementioned four magnetic elements, but the number of grooves 5-1041 and magnetic elements 5-ME is not limited to this embodiment. The central opening 5-1043 is configured to accommodate the first drive coil 5-CL1 to the fourth drive coil 5-CL4 and the first movable member 5-1081 to the fourth movable member 5-1084.

[0897] In this embodiment, the first driving coil 5-CL1 to the fourth driving coil 5-CL4 can be wound coils, respectively disposed on the first movable member 5-1081 to the fourth movable member 5-1084. When the first driving coil 5-CL1 to the fourth driving coil 5-CL4 are energized, they can generate electromagnetic force with the first magnetic element 5-MG1 to the fourth magnetic element 5-MG4 respectively, thereby driving the first movable member.

[0898] At least one of the four movable components 5-1081 to 5-1084 moves relative to the base 5-112 and the frame 5-104 along the direction of the optical axis 5-O (Z-axis direction) to perform autofocusing or optical image stabilization.

[0899] The drive components of the drive module 5-DM can operate individually or together. For example, the first drive component 5-DA1 is configured to drive the first movable member 5-1081 to move relative to the fixed component 5-FA, and the second drive component 5-DA2 is configured to drive the second movable member 5-1082 to move relative to the fixed component 5-FA and the first movable member 5-1081, and so on.

[0900] Furthermore, such as Figure 42As shown, in this embodiment, the fixing component 5-FA may further include at least one circuit component 5-170, configured to be electrically connected to the drive module 5-DM via a first elastic element 5-106 or a second elastic element 5-110. The circuit component 5-170 may be implemented by insert molding, but is not limited thereto. Furthermore, the circuit component 5-170, the first elastic element 5-106, and the second elastic element 5-110 may constitute a circuit assembly.

[0901] Next, please refer to Figures 44 to 46 , Figure 44 This is a schematic diagram showing the first optical element 5-OE according to an embodiment of the present disclosure not being pushed by the molding part 5-101. Figure 45 as well as Figure 46 This is a schematic diagram showing the first optical element 5-OE according to an embodiment of the present disclosure after being pushed by the molding part 5-101. Figure 44 As shown, the first optical element 5-OE can be a liquid lens, comprising a liquid lens element 5-OE1 and a fixing member 5-OE2. The liquid lens element 5-OE1 is disposed within the fixing member 5-OE2, which has a hollow structure. The fixing member 5-OE2 has the function of protecting and supporting the liquid lens element 5-OE1. The shaping member 5-101 is disposed below the liquid lens element 5-OE1 and the fixing member 5-OE2. The bottom of the fixing member 5-OE2 can be a thin film, so the shaping member 5-101 can be used to change the shape of the liquid lens element 5-OE1.

[0902] Figure 44 The liquid lens element 5-OE1 remains undeformed, and the shaping part 5-101 is held in an initial position. The liquid lens element 5-OE1 has an optical axis 5-O. When a driving current is applied to the driving coil of the driving module 5-DM, a magnetic force is generated between the driving coil and the corresponding magnetic element. The driving module 5-DM drives the movable component 5-MA through this magnetic force, so that the movable component 5-MA drives the shaping part 5-101 through the connecting component 5-CA to push the lower side of the liquid lens element 5-OE1, thereby causing the liquid lens element 5-OE1 to deform.

[0903] like Figure 42 as well as Figure 45 As shown, when the first drive component 5-DA1 and the third drive component 5-DA3 of the drive module 5-DM provide the same magnitude of thrust 5-F1 and 5-F3, the shaping part 5-101 will translate along the optical axis 5-O. At this time, the lens curvature coefficient of the liquid lens element 5-OE1 is compared with... Figure 44The curvature of the liquid lens element 5-OE1 changes, that is, the shape of the liquid lens element 5-OE1 is altered. This changes the optical properties of the liquid lens element 5-OE1, thereby achieving the effect of optical zoom.

[0904] Similarly, see Figure 46 When the drive module 5-DM drives the molded part 5-101 to tilt, such as Figure 46 Unequal thrusts 5-F1 and 5-F3 are applied to both sides of the liquid lens element 5-OE1 by the molding part 5-101, causing the optical axis 5-O of the liquid lens element 5-OE1 to rotate and deviate from the main axis 5-AX, that is, there is an included angle 5-θ1 between the two, which changes the optical properties of the liquid lens element 5-OE1, thereby achieving the effects of optical zoom, focusing or optical image stabilization.

[0905] Please refer to Figure 47 , Figure 47 According to an embodiment of the present disclosure Figure 43 An enlarged schematic diagram of the optical system 5-100. (See attached diagram.) Figure 47 As shown, the fourth connector 5-1054 has an elastic portion 5-1055 and a rigid portion 5-1056. The elastic portion 5-1055 is not parallel to the main shaft 5-AX, for example, it is perpendicular to the main shaft 5-AX. The rigid portion 5-1056 is connected between the elastic portion 5-1055 and the fourth movable member 5-1084 of the movable assembly 5-MA. It is worth noting that in the direction of the main shaft 5-AX, the distance 5-ds1 between the movable element surface 5-103S (top surface) of the movable element 5-103 and the first optical element 5-OE is smaller than the distance 5-ds2 between the adhesive member 5-AD and the first optical element 5-OE. Based on the above design, it is possible to avoid the rigid portion 5-1056 and the adhesive member 5-AD abutting against the first optical element 5-OE when the movable assembly 5-MA moves, thereby preventing damage to the first optical element 5-OE.

[0906] Please refer to Figure 48 , Figure 48 This is a top view of a portion of the structure of an optical system 5-100 according to an embodiment of the present disclosure. Figure 48 As shown, when viewed along the main axis 5-AX, the elastic portion of each connector extends outward from the movable element 5-103. For example, the elastic portion 5-1055 of the fourth connector 5-1054 extends outward from the movable element 5-103. Furthermore, in this embodiment, the connecting assembly 5-CA includes four connectors, and when viewed along the main axis 5-AX, the elastic portions of these connectors are mirror-symmetrical with respect to a first transverse axis 5-AX1 or a second transverse axis 5-AX2.

[0907] Specifically, the elastic portion of each connector can be formed by a chord extending along multiple directions perpendicular to the main axis 5-AX, i.e., extending along the XY plane. Additionally, as... Figure 48 As shown, when viewed along the direction of the main axis 5-AX, the string of the elastic part 5-1055 of the fourth connector 5-1054 has a fixed width 5-WS, and both ends of the string are connected to the movable element 5-103.

[0908] In this embodiment, the string of the elastic part 5-1055 may have two cantilevers. For example, the string of the elastic part 5-1055 of the fourth connector 5-1054 may have a first cantilever 5-1057 and a second cantilever 5-1058, and the first cantilever 5-1057 and the second cantilever 5-1058 are symmetrical about the first horizontal axis 5-AX1.

[0909] The design based on the elastic part of the string can increase the stability of the moving component 5-MA driving the moving element 5-103 via the connecting component 5-CA. For example, when the fourth moving component 5-1084 moves along the direction of the main axis 5-AX, the moving element 5-103 will only be driven to move along the direction of the main axis 5-AX, and will not move along the first horizontal axis 5-AX1 or the second horizontal axis 5-AX2.

[0910] Please refer to Figure 47 as well as Figure 49 , Figure 49 This is a top view of a partial structure of an optical system 5-100 according to an embodiment of the present disclosure. When viewed along the principal axis 5-AX, a surface 5-OEBS of the first optical element 5-OE at least partially overlaps with the chord. Surface 5-OEBS may be... Figure 47 In the middle, the liquid lens element 5-OE1 is projected along the optical axis 5-O onto the bottom surface of the fixture 5-OE2.

[0911] like Figure 49 As shown, surface 5-OEBS includes a first portion 5-POC1, a second portion 5-POC2, and a pressure-applied surface 5-PRS. The pressure-applied surface 5-PRS can be... Figure 47 The area where the molded part 5-101 contacts the bottom surface of the fixing part 5-OE2, and in this embodiment, the pressure-applied surface 5-PRS is an annular area.

[0912] Furthermore, the first portion 5-POC1 is located inside the pressure-applied surface 5-PRS, and the second portion 5-POC2 is located outside the pressure-applied surface 5-PRS, and the chord of the elastic portion 5-1055 of each connector at least partially overlaps with the second portion 5-POC2. Moreover, in this embodiment, the second portion 5-POC2 also partially overlaps with the adhesive 5-AD, but is not limited thereto. In other embodiments, the second portion 5-POC2 may not overlap with the adhesive 5-AD.

[0913] Please refer to Figure 50 , Figure 50 This is a cross-sectional schematic diagram of an optical system 5-100 according to another embodiment of the present disclosure. This embodiment is similar to the previous embodiment, except that the rigid part 5-1056 in this embodiment can be composed of two chords, and these two chords are mirror-symmetrical with respect to the main axis 5-AX. Based on the design of the rigid part 5-1056 in this embodiment, bending along the XY plane can be avoided when the moving member (such as the first moving member 5-1081) moves along the main axis 5-AX, and the problem of easy breakage of the rigid part 5-1056 can also be avoided.

[0914] Please refer to Figure 51 and Figure 52 , Figure 51 This is a perspective view of the combination of the movable element 5-103 and the plurality of elastic parts 5-1055 according to another embodiment of the present disclosure, and Figure 52 This is a top view of the combination of the movable element 5-103 and a plurality of elastic portions 5-1055 according to another embodiment of the present disclosure. In this embodiment, each elastic portion 5-1055 is composed of a single string, and this string has a non-uniform width. Based on this design of the elastic portion 5-1055, the problem of stress concentration causing damage to the elastic portion 5-1055 can be avoided.

[0915] like Figure 52 As shown, when viewed along the main axis 5-AX, each chord has a first end 5-10551 and a second end 5-10552. The first end 5-10551 is connected to the movable element 5-103, and the second end 5-10552 is connected to a corresponding rigid part 5-1056, for example, via an adhesive member 5-AD. Furthermore, these connecting parts (including the elastic part 5-1055 and the rigid part 5-1056) are arranged rotationally symmetrically with respect to the main axis 5-AX.

[0916] Please refer to Figure 53 , Figure 53This is a perspective view of the combination of a movable element 5-103 and a plurality of elastic portions 5-1055 according to another embodiment of the present disclosure. In this embodiment, the string can be connected to the movable element 5-103 by an adhesive member 5-AD. Specifically, as Figure 53 As shown, the first end 5-10551 may have an opening 5-1055H, and the adhesive 5-AD may be disposed in the opening 5-1055H, so that the elastic part 5-1055 is fixed to the movable element 5-103.

[0917] In this embodiment, the elastic portion 5-1055 and the movable element 5-103 can be made of metal. Alternatively, in other embodiments, the movable element 5-103 can be integrally formed with these elastic portions 5-1055 (chords), for example, using stamping technology. Based on this integral forming design, the convenience of assembly without positioning and the increased strength can be achieved.

[0918] Please refer to Figure 54 , Figure 54 This is a perspective view of the combination of a movable element 5-103 and a plurality of elastic portions 5-1055 according to another embodiment of the present disclosure. In this embodiment, the movable element 5-103 is made of plastic, and at least one positioning portion 5-103P may be formed on the movable element 5-103, corresponding to the opening 5-1055H, configured to position the first end 5-10551 of the string. Additionally, an adhesive member 5-AD may be further provided within the opening 5-1055H to fix the first end 5-10551 to the movable element 5-103. The design of the positioning portion 5-103P increases the ease of assembly and the accuracy of positioning.

[0919] Please refer to Figure 55 , Figure 55 This is a perspective view of a movable element 5-103 and a plurality of elastic portions 5-1055 according to another embodiment of the present disclosure. In this embodiment, the movable element 5-103 is made of plastic, and the elastic portions 5-1055 (chords) are made of metal and are embedded in the movable element 5-103 using insert molding technology. Based on this design, the ease of assembly of the optical system 5-100 can be improved.

[0920] This disclosure provides an optical system comprising a first optical element 5-OE, a shaping element 5-101, a movable element 5-103, a fixed assembly 5-FA, a connecting assembly 5-CA, a movable assembly 5-MA, and a drive module 5-DM. The movable element 5-103 is configured to be connected to the first optical element 5-OE via the shaping element 5-101, and the movable assembly 5-MA is connected to the movable element 5-103 via the connecting assembly 5-CA. When the drive module 5-DM is configured to drive the movable assembly 5-MA to move relative to the fixed assembly 5-FA, it can move the movable element 5-103, causing the shaping element 5-101 to press against the bottom of the first optical element 5-OE, thereby changing the optical properties of the liquid lens element 5-OE1.

[0921] In addition, in some embodiments, the string of the elastic part 5-1055 may be designed to have two cantilevered arms, and based on this string design, the stability of the moving component 5-MA driving the moving element 5-103 via the connecting component 5-CA can be increased.

[0922] Sixth set of embodiments.

[0923] Please refer to Figure 56 , Figure 56 This is a schematic diagram of an optical system 6-100 mounted on a portable electronic device 6-50 according to an embodiment of the present invention. The portable electronic device 6-50 can be any portable or handheld device, such as a digital personal assistant (PDA), smartphone, tablet, mobile phone, mobile internet device (MID), laptop computer, automotive computer, digital camera, digital media player, gaming device, or any type of mobile computing device; however, those skilled in the art will understand that the present invention is not limited thereto. In this embodiment, the optical system 6-100 can be a lens system with a long focal length, which can provide the user with better shooting results, wherein light can enter the optical system 6-100 through the opening 6-52 to produce one or more digital images.

[0924] Please refer to Figure 57 as well as Figure 58 , Figure 57 This is a three-dimensional structural schematic diagram of an optical system 6-100 according to an embodiment of the present disclosure, and Figure 58This is a cross-sectional schematic diagram of an optical system 6-100 according to an embodiment of the present disclosure. In this embodiment, the optical system 6-100 includes a housing 6-102 embedded in a portable electronic device 6-50, and the optical system 6-100 also includes a fixing member 6-104, a first optical module 6-110, a second optical module 6-120, a reflective optical module 6-140 (a fourth optical module), and a photosensitive module 6-180, all housed within the housing 6-102.

[0925] The fixing member 6-104 can be a plate-like structure, fixed to the bottom surface of the housing 6-102. The first optical module 6-110, the second optical module 6-120, the reflective optical module 6-140, and the photosensitive module 6-180 are fixedly disposed on the fixing member 6-104 and arranged along a first direction (X-axis direction). In the first direction, the first optical module 6-110 is disposed between the reflective optical module 6-140 (the fourth optical module) and the second optical module 6-120.

[0926] It is worth noting that these optical modules, as well as the photosensitive module 6-180, may have a gap between them and the fixing member 6-104. For example, such as Figure 58 As shown, a gap is formed between the fixing member 6-104 and the first optical module 6-110, and another gap is formed between the fixing member 6-104 and the second optical module 6-120. The optical system 6-100 may include a plurality of bonding elements 6-AD to fill these gaps so that the optical modules can be fixed to the fixing member 104.

[0927] Furthermore, the first optical module 6-110 has a first housing 6-1102, and the second optical module 6-120 has a second housing 6-1202. The first housing 6-1102 has a first wall surface 6-1102S, and the second housing 6-1202 has a second wall surface 6-1202S, with the first wall surface 6-1102S facing the second wall surface 6-1202S. In this embodiment, the first wall surface 6-1102S does not contact the second wall surface 6-1202S, meaning that there is a gap 6-GP between the first wall surface 6-1102S and the second wall surface 6-1202S.

[0928] Similarly, the housing 6-1402 of the reflective optical module 6-140 also has a gap between it and the first housing 6-1102, and so on. That is, each module in the optical system 6-100 of this disclosure has its own housing, and adjacent housings do not contact each other.

[0929] Please refer to Figure 58 and Figure 59 , Figure 59This is a top view schematic diagram of an optical system 6-100 according to an embodiment of the present disclosure. A first optical element (optical element 6-OE) in a first optical module 6-110 has a first optical axis 6-O1, and a second optical element (lens 6-1220) in a second optical module 6-120 has a second optical axis 6-O2. The first optical module 6-110 and the second optical module 6-120 are configured to be adjusted before the bonding element 6-AD is cured so that the first optical axis 6-O1 is aligned with the second optical axis 6-O2.

[0930] For example, such as Figure 59 As shown, when the first optical module 6-110 and the second optical module 6-120 are respectively mounted on the fixing member 6-104 using the bonding element 6-AD, the second optical axis 6-O2 may not be aligned with the first optical axis 6-O1 due to assembly tolerances. In this case, the assembler can rotate the second optical module 6-120 to align the second optical axis 6-O2 with the first optical axis 6-O1, and then cure the bonding element 6-AD to stably fix the first optical module 6-110 and the second optical module 6-120 on the fixing member 6-104.

[0931] In one embodiment of this disclosure, the bonding element 6-AD may be an ultraviolet (UV) adhesive, but is not limited thereto, which may be cured by ultraviolet irradiation.

[0932] It is worth noting that, such as Figure 58 and Figure 59 As shown, when viewed along a second direction (Y-axis direction) perpendicular to the first direction (X-axis direction), a drive component 6-DA of the first optical module 6-110 and a lens 6-1220 (second optical element) of the second optical module 6-120 at least partially overlap.

[0933] Furthermore, such as Figures 57 to 59 As shown, the first optical module 6-110 further includes a fifth optical module 6-150 and a sixth optical module 6-160. The fifth optical module 6-150 may include an aperture, and the sixth optical module 6-160 may include a shutter. The fifth optical module 6-150 is positioned above the reflective optical module 6-140. Figure 58 Furthermore, the sixth optical module 6-160 is located between the photosensitive module 6-180 and the second optical module 6-120.

[0934] The fifth optical module 6-150 is configured to receive an incident light 6-L along a third direction (Z-axis). After passing through the fifth optical module 6-150, the incident light 6-L is received by the reflective optical module 6-140, which then reflects a reflected light 6-RL. The reflected light 6-RL moves along a first direction, sequentially passing through the first optical module 6-110, the second optical module 6-120, and the sixth optical module 6-160, before being received by the photosensitive module 6-180 to generate a digital image.

[0935] Next, the specific structure of the second optical module 6-120 will be explained. For example... Figure 58 As shown, the second optical module 6-120 mainly includes a lens driving mechanism 6-1210 and a lens 6-1220, wherein the lens driving mechanism 6-1210 is used to drive the lens 6-1220 to move. For example, the lens driving mechanism 6-1210 may include a lens support 6-1211, an outer frame 6-1212, two springs 6-1213, at least one coil 6-1214, and at least one magnetic element 6-1215. The coil 6-1214 and the magnetic element 6-1215 can constitute a second driving assembly.

[0936] The aforementioned lens 6-1220 (second optical element) is fixed in the lens mount 6-1211 (second connector). Two springs 6-1213 connect the lens mount 6-1211 and the outer frame 6-1212, and are located on opposite sides of the lens mount 6-1211, so that the lens mount 6-1211 is movably suspended in the outer frame 6-1212. A coil 6-1214 and a magnetic element 6-1215 are respectively disposed on the lens mount 6-1211 and the outer frame 6-1212, and correspond to each other. When current flows into the coil 6-1214, an electromagnetic effect is generated between the coil 6-1214 and the magnetic element 6-1215, and the lens mount 6-1211 and the lens 6-1220 disposed on the lens mount 6-1211 can be driven to move relative to the outer frame 6-1212 (second fixing part), for example, moving along the X-axis direction. Additionally, the second optical module 6-120 may also include a sensing element 6-1216 configured to sense the movement of the lens mount 6-1211 relative to the outer frame 6-1212.

[0937] Next, the specific structure of the reflective optical module 6-140 will be explained. For example... Figure 58 As shown, the reflective optical module 6-140 mainly includes an optical element 6-1410, an optical element carrier 6-1420, a frame 6-1430, at least one first pivot 6-1450, a first drive module 6-1460, and a position detector 6-1401.

[0938] The optical element carrier 6-1420 can be pivotally connected to the frame 6-1430 via the first pivot 6-1450. When the optical element carrier 6-1420 rotates relative to the frame 6-1430, the optical element 6-1410 mounted thereon can simultaneously rotate relative to the frame 6-1430. The aforementioned optical element 6-1410 can be, for example, a prism or a mirror.

[0939] The first drive module 6-1460 may include a first electromagnetic drive component 6-1461 and a second electromagnetic drive component 6-1462, which are respectively disposed on the frame 6-1430 and the optical element carrier 6-1420, and their positions correspond to each other.

[0940] For example, the first electromagnetic drive assembly 6-1461 may include a drive coil, while the second electromagnetic drive assembly 6-1462 may include a magnet. When current is applied to the drive coil (first electromagnetic drive assembly 6-1461), an electromagnetic interaction is generated between the drive coil and the magnet. This causes the optical element carrier 6-1420 and the optical element 6-1410 to rotate relative to the frame 6-1430 around the first pivot 6-1450, thereby adjusting the position of the reflected light 6-RL on the photosensitive module 6-180.

[0941] Position detector 6-1401 can be disposed on the frame 6-1430 and correspond to the aforementioned second electromagnetic drive component 6-1462, so as to obtain the rotation angle of optical element 6-1410 by detecting the position of the second electromagnetic drive component 6-1462. The aforementioned position detector 6-1401 can be, for example, a Hall effect sensor, a magnetoresistive effect sensor, a giant magnetoresistive effect sensor, a tunneling magnetoresistive effect sensor, or a magnetic flux sensor.

[0942] Next, the specific structure of the first optical module 6-110 will be explained. Please refer to [link / reference needed]. Figures 60 to 62 , Figure 60 This is a perspective view of a first optical module 6-110 according to an embodiment of the present disclosure. Figure 61 This is an exploded view of a first optical module 6-110 according to an embodiment of the present disclosure, and Figure 62 For the first optical module 6-110 according to an embodiment of the present disclosure along Figure 60A cross-sectional view of line segment 6-A-6-A' is shown. In this embodiment, the first optical module 6-110 includes an optical element module 6-OEM, a fixed component 6-FA (first fixed part), a movable component 6-MA (first movable component), a driving component 6-DA (first driving component), and a position sensing component 6-SA. The movable component 6-MA is an optical element 6-OE (first optical element) corresponding to the optical element module 6-OEM, and the movable component 6-MA is movable relative to the fixed component 6-FA. The driving component 6-DA is used to drive the movable component 6-MA to move relative to the fixed component 6-FA, and the position sensing component 6-SA is used to sense the position and movement of the movable component 6-MA relative to the fixed component 6-FA.

[0943] like Figure 61 As shown, the fixing assembly 6-FA may include a top frame 6-1102, a side frame 6-1104, and a base 6-1112. The top frame 6-1102 is fixedly connected to the side frame 6-1104, and the side frame 6-1104 is fixedly connected to the base 6-1112. The top frame 6-1102 has an opening 6-11021 and four protrusions 6-11023, and the optical element module 6-OEM is fixedly disposed on these protrusions 6-11023. The side frame 6-1104 and the base 6-1112 may form an accommodating space 6-AS. Figure 62 The configuration accommodates the active component 6-MA and the drive component 6-DA. Additionally, the fixed component 6-FA may also include a circuit board 6-1114, which is fixedly disposed on one side of the side frame 6-1104.

[0944] The movable component 6-MA includes a movable member 6-1108 and two elastic elements 6-1106. The movable member 6-1108 is movably disposed within the accommodating space 6-AS, and the elastic elements 6-1106 are disposed between the side frame 6-1104 and the base 6-1112. Additionally, the drive component 6-DA may include a drive coil 6-DCL, a first drive magnetic element 6-MG1, and a second drive magnetic element 6-MG2.

[0945] like Figure 61As shown, the drive coil 6-DCL is disposed in the movable member 6-1108. The movable member 6-1108 may have multiple grooves 6-1108C located around the drive coil 6-DCL, and each groove 6-1108C can accommodate a bonding element 6-AD to fix the drive coil 6-DCL in the movable member 6-1108. The first driving magnetic element 6-MG1 and the second driving magnetic element 6-MG2 correspond to the drive coil 6-DCL and are fixedly disposed on the fixing assembly 6-FA. Specifically, the first driving magnetic element 6-MG1 and the second driving magnetic element 6-MG2 are disposed on the side frame 6-1104 and located in the accommodating space 6-AS. In addition, the drive coil 6-DCL is electrically connected to the circuit board 6-1114 via two elastic elements 6-1106, for example, through... Figure 57 The solder in the 6-SD connection circuit board 6-1114.

[0946] In this embodiment, the position sensing component 6-SA includes a sensed unit 6-SAU and a sensing element 6-SE. The sensing element 6-SE is disposed on the circuit board 6-1114 and corresponds to the sensed unit 6-SAU. The sensed unit 6-SAU may have a plurality of reference magnetic elements 6-RGE, which are arranged along a first direction (e.g., the X-axis direction). The sensed unit 6-SAU and the sensing element 6-SE are arranged along an arrangement direction (Y-axis direction), and the aforementioned first direction is not parallel to the aforementioned arrangement direction.

[0947] like Figure 61 and Figure 62 As shown, the optical element 6-OE is a liquid lens, and the optical element 6-OE may also include a flow channel 6-OE1. A light-transmitting liquid is disposed within the flow channel 6-OE1 and the optical element 6-OE. Furthermore, the optical element drive mechanism 6-1100 may also include a molding member 6-1101 (first connector), a protrusion 6-11081 of the movable member 6-1108 is inserted into the molding member 6-1101, and the molding member 6-1101 abuts against one end of the flow channel 6-OE1 (e.g., ...). Figure 62 (Left end of the middle).

[0948] In this embodiment, the optical element 6-OE and the flow channel 6-OE1 can be thin-film structures along one or both sides of the X-axis. When the drive coil 6-DCL is energized, it generates an electromagnetic driving force with the first drive magnetic element 6-MG1 and the second drive magnetic element 6-MG2. This electromagnetic driving force drives the movable member 6-1108 to move along the X-axis. Therefore, the movable member 6-1108 and the molding part 6-1101 push the flow channel 6-OE1, causing some of the liquid in the flow channel 6-OE1 to flow towards the optical element 6-OE, thereby causing the optical element 6-OE to deform. This changes the optical properties of the optical element 6-OE, thereby achieving the effect of optical zoom.

[0949] like Figure 62 As shown, the movable member 6-1108 may have a spacer structure 6-1108SS (spacer element) disposed between these reference magnetic elements 6-RGE. When viewed along the first direction (X-axis), the reference magnetic elements 6-RGE partially overlap with the spacer structure 6-1108SS, and the spacer structure 6-1108SS is made of a non-magnetic material, such as plastic. Furthermore, the first optical module 6-110 may include a plurality of bonding elements 6-AD respectively disposed between the spacer structure 6-1108SS and these reference magnetic elements 6-RGE, so that the reference magnetic elements 6-RGE are fixed to the movable member 6-1108.

[0950] Please refer to Figure 63 , Figure 63 This is a top view schematic diagram of an optical system 6-100 according to another embodiment of the present disclosure. In this embodiment, the optical system 6-100 may further include a third optical module 6-130, and the third optical module 6-130 may have the same structure as the first optical module 6-110. For example, the third optical module 6-130 may further include a third driving component (such as driving component 6-DA), a third fixing part (such as fixing component 6-FA), and a third connector (such as molding part 6-1101).

[0951] When viewed along the first direction (X-axis), the magnetic element 6-1215 of the second drive assembly at least partially overlaps with a third optical element (e.g., optical element 6-OE) of the third optical module 6-130. When viewed along the second direction (Y-axis), the drive coil 6-DCL of the third drive assembly of the third optical module 6-130 partially overlaps with the lens 6-1220 (the second optical element).

[0952] It is worth noting that the optical element 6-OE (first optical element) of the first optical module 6-110 and the optical element 6-OE (third optical element) of the third optical module 6-130 are located on opposite sides of the magnetic element 6-1215 of the second drive assembly. Based on the above design, the second optical module 6-120 can be configured with a longer lens 6-1220 to enable the optical system 6-100 to achieve better shooting results.

[0953] Furthermore, the first optical module 6-110 to the reflective optical module 6-140 of this disclosure are arranged along a first direction (X-axis direction) and are not stacked along a third direction (Z-axis direction), wherein the third direction is perpendicular to the first direction (X-axis direction) and the second direction (Y-axis direction).

[0954] This disclosure provides an optical system having multiple modules disposed within a housing 6-102 and fixable to a fixing member 6-104. These modules may include a liquid lens module, a reflective optical module, an aperture, or a photosensitive module. The configuration of these modules on the fixing member 6-104 can be adjusted according to different design requirements to achieve better performance of the optical system.

[0955] In addition, the first optical module 6-110 to the reflective optical module 6-140 in these modules are not stacked along the Z-axis direction, thus enabling the optical system of this disclosure to achieve miniaturization.

[0956] Seventh set of embodiments.

[0957] Please refer to the following first. Figure 64 In one embodiment of this disclosure, the optical element driving mechanism 7-100 can be installed in an electronic device 7-1 for taking pictures or videos. The aforementioned electronic device 7-1 can be, for example, a smartphone or a digital camera, but this disclosure is not limited thereto. It should be noted that... Figure 64 The positional and size relationship between the optical element driving mechanism 7-100 and the electronic device 7-1 shown is merely an example and not a limitation on the positional and size relationship between the optical element driving mechanism 7-100 and the electronic device 7-1. In practice, the optical element driving mechanism 7-100 can be installed in different positions within the electronic device 7-1 according to different needs.

[0958] Please see Figure 65 The optical element drive mechanism 7-100 has an optical axis 7-O that passes through the optical element drive mechanism 7-100. (See also...) Figure 66The optical element driving mechanism 7-100 includes a movable part 7-10, a fixed part 7-20, and a driving assembly 7-30. The movable part 7-10 includes a portion of at least three sensing components (which may consist of magnetic elements and magnetic field sensing units, or optical reference objects and photosensing elements, etc.) 7-11, four fixed elements 7-12, and a support 7-13. The fixed part 7-20 includes an outer frame 7-21, a base 7-22, and a photosensitive element holder 7-23. The driving assembly 7-30 includes four piezoelectric elements 7-31, four deformation elements 7-32, and four connecting elements 7-33. Please refer to [further details omitted]. Figure 65 The movable part 7-10 of the optical element driving mechanism 7-100 contacts an optical element 7-110, and the photosensitive element holder 7-23 contacts and holds a photosensitive element (not shown) with the base 7-22. The outer frame 7-21 has four side walls 7-21a, which are parallel to the optical axis 7-O, and there is a gap 7-T between the outer frame 7-21 and the driving assembly 7-30. That is, the side walls 7-21a do not directly contact the driving assembly 7-30. In this way, when the optical element driving mechanism 7-100 is impacted, the driving assembly 7-30 can be prevented from colliding with the outer frame 7-21, thereby preventing damage to the driving assembly 7-30. Figure 65 and Figure 66 As shown, in this embodiment, the optical element 7-110 can be a lens. More specifically, the support 7-13 of the movable part 7-10 has a hollow annular structure, and has a through hole 7-13a and a threaded structure 7-13b formed on the through hole 7-13a, and the threaded structure 7-13b can lock the optical element 7-110 in the through hole 7-13a.

[0959] Please see Figure 67 At least three sensors 7-11 are disposed on the support 7-13 to detect the movement of the support 7-13 of the movable part 7-10 relative to the fixed part 7-20. It should be noted that the number of sensors 7-11 may also be four or more. The base 7-22 has a stepped portion 7-22a and a surface portion 7-22b. The outer frame 7-21 is placed on the stepped portion 7-22a (see [reference]). Figure 65This design allows the outer frame 7-21 to be more securely attached to the base 7-22, increasing the contact area to reduce the degree of movement of the outer frame 7-21 relative to the base 7-22. The piezoelectric element 7-31 directly contacts and is fixed to the surface portion 7-22b of the base 7-22. The deformation element 7-32 corresponds to the piezoelectric element 7-31, and also directly contacts and is fixed to the surface portion 7-22b. In some embodiments, the drive assembly 7-30 includes at least two piezoelectric elements 7-31 and corresponding at least two deformation elements 7-32, and each of the piezoelectric elements 7-31 independently drives the corresponding deformation element 7-32. Figure 67 As shown, in this embodiment, the four piezoelectric elements 7-31 of the driving assembly 7-30 correspond to four deformation elements 7-32, and each of the piezoelectric elements 7-31 independently drives the corresponding deformation element 7-32. It should be noted that the number of piezoelectric elements 7-31, deformation elements 7-32, and connecting elements 7-33 in the driving assembly 7-30 is not limited to four. In other embodiments, the number of piezoelectric elements 7-31, deformation elements 7-32, and connecting elements 7-33 may be one, two, three, or other numbers.

[0960] like Figure 67 As shown, when viewed along a direction perpendicular to the optical axis 7-O, the lower half 7-32a of the deformation element 7-32 overlaps with the piezoelectric element 7-31, while the upper half 7-32b of the deformation element 7-32 is the portion of the deformation element 7-32 exposed upwards from the piezoelectric element 7-31. The piezoelectric element 7-31 can be composed of two pieces of piezoelectric material, and the two pieces of piezoelectric material are in contact with the lower half 7-32a of the deformation element 7-32 respectively. After the piezoelectric material receives an external current and deforms, the piezoelectric element 7-31 drives the deformation element 7-32 to deform along an extension direction parallel to the optical axis 7-O. That is, after receiving an external current, the extension directions of the piezoelectric element 7-31 and the deformation element 7-32 are parallel to the optical axis 7-O. The upper half 7-32b of the deformation element 7-32 contacts the connecting element 7-33, but the upper half 7-32b of the deformation element 7-32 does not contact the piezoelectric element 7-31, while the connecting element 7-33 contacts the carrier 7-13. Thus, when the piezoelectric material receives an external current and deforms, causing the deformation element 7-32 to deform, the connecting element 7-33 will move along with the upper half 7-32b of the deformation element 7-32, thereby driving the carrier 7-13 to move relative to the fixed part 7-20 along the optical axis 7-O. The movable part 7-10 is movably connected to the fixed part 7-20 via the connecting element 7-33 and the fixed element 7-12.

[0961] Please see Figure 68The piezoelectric element 7-31 and the deformation element 7-32 have a plate-like structure. In this embodiment, the lower half 7-32a of the deformable element 7-32 is partially exposed downwards outside the piezoelectric element 7-31. This increases the contact area between the deformable element 7-32 and the surface 7-22b of the base 7-22, allowing the deformable element 7-32 to be more firmly attached to the surface 7-22b. Furthermore, an elastic adhesive material (e.g., a soft adhesive) can be used during attachment, allowing it to be roughly fixed to the base 7-22 without affecting the movement of the piezoelectric element 7-31 and the deformable element 7-32. Additionally, a support structure can be provided between the deformable element 7-32 (or the piezoelectric element 7-31) and the fixing part to more reliably restrict the position of the piezoelectric element 7-31 and the deformable element 7-32. Moreover, a harder adhesive can be used for the middle part (protruding towards the base) of the lower half 7-32a, while a softer adhesive can be used for the two sides (protruding towards the base) of the lower half 7-32a, further enhancing the bonding effect. The upper half 7-32b of the deformable element 7-32 has two extensions 7-32b'. The extensions 7-32b' extend a certain distance in a direction substantially parallel to the optical axis 7-O, and then extend in a direction substantially perpendicular to the optical axis 7-O, facing each other. The connecting element 7-33 contacts a contact surface 7-32b" of the corresponding extension 7-32b'. Specifically, the connecting element 7-33 rests against the contact surface 7-32b" by friction. The deformable element 7-32 is made of a deformable material (e.g., metal); however, the contact surface 7-32b" must be rigid so that the friction between the contact surface 7-32b" and the connecting element 7-33 does not change due to the deformation of the deformable element 7-32. Alternatively, in other embodiments not shown, an elastic adhesive material can be disposed between the upper half 7-32b and the fixing portion, or between the piezoelectric element 7-31 and the fixing portion.

[0962] Please see Figure 69 The connecting element 7-33 includes a first portion 7-33a, a bent portion 7-33b, and a second portion 7-33c. The first portion 7-33a is directly connected to the bent portion 7-33b, and the second portion 7-33c is also directly connected to the bent portion 7-33b, but the first portion 7-33a is not directly connected to the second portion 7-33c. The first portion 7-33a and the bent portion 7-33b are separated by a dashed line 7-W1, and the bent portion 7-33b and the second portion 7-33c are separated by a dashed line 7-W2. Figure 69In the embodiment, the first portion 7-33a is non-linear and has a bend point 7-C1 and a bend point 7-C2, while the second portion 7-33c is linear. In general, the connecting element 7-33 is essentially a U-shaped structure consisting of a closed structure and an opening. The connecting element 7-33 is flexible and has a preload. The construction of the connecting element 7-33 with a non-linear first portion 7-33a and a linear second portion 7-33c allows the connecting element 7-33 to utilize this preload more effectively. This preload drives the first portion 7-33a and the second portion 7-33c to rest against the contact surface 7-32b” of the deformable element 7-32 in opposite directions, preventing the connecting element 7-33 from moving relative to the contact surface 7-32b”.

[0963] Please see Figure 70 The first portion 7-33a of the connecting element 7-33 has a first surface 7-33a', and the second portion 7-33c has a second surface 7-33c'. The first surface 7-33a' faces away from the movable portion 7-10, while the second surface 7-33c' faces the movable portion 7-10. The first portion 7-33a also includes a first opening 7-33a', and the second portion 7-33c also includes a second opening 7-33c'. Generally, the first opening 7-33a' and the second opening 7-33c' can be circular openings. However, the shapes of the first opening 7-33a' and the second opening 7-33c' can be other non-circular openings depending on actual needs. The fixing element 7-12 of the movable portion 7-10 passes through the first opening 7-33a' and the second opening 7-33c'.

[0964] In one embodiment, the size 7-33a”' of the first opening 7-33a” is smaller than the size 7-33c”' of the second opening 7-33c”. Therefore, the shortest distance 7-S2 between the second surface 7-33c’ and the fixing element 7-12 is greater than the shortest distance 7-S1 between the first surface 7-33a’ and the fixing element 7-12. As a result, the second opening 7-33c” of the second part 7-33c provides more movement space for the fixing element 7-12 than the first opening 7-33a” of the first part 7-33a, so that when the support 7-13 rotates relative to the fixing part 7-20, it will not be affected by the second opening 7-33c”, and thus the angle of rotation of the support 7-13 will not be unnecessarily restricted.

[0965] Please see Figure 71 and Figure 72In another embodiment, the dimensions 7-33a”' of the first opening 7-33a” are the same as the dimensions 7-33c”' of the second opening 7-33c”; however, the dimensions of the fixing element 7-12 are not constant. The fixing element 7-12 has a first dimension 7-12a at the first opening 7-33a”, and a second dimension 7-12b at the second opening 7-33c”, and the first dimension 7-12a is larger than the second dimension 7-12b. In this configuration, the shortest distance 7-S2 between the second surface 7-33c’ and the fixing element 7-12 is greater than the shortest distance 7-S1 between the first surface 7-33a’ and the fixing element 7-12. In this way, the second opening 7-33c” of the second part 7-33c provides more movement space for the fixing element 7-12 than the first opening 7-33a” of the first part 7-33a, so that when the bearing seat 7-13 rotates relative to the fixing part 7-20, it will not be affected by the second opening 7-33c”, and thus the angle of rotation of the bearing seat 7-13 will not be unnecessarily restricted.

[0966] Please see Figure 73 After the second portion 7-33c of the connecting element 7-33 of the drive assembly 7-30 extends in a direction perpendicular to the optical axis 7-O, it contacts the support 7-13 of the movable part 7-10. After the first portion 7-33a of the connecting element 7-33 extends in a direction perpendicular to the optical axis 7-O, it bends at the bending points 7-C1 and 7-C2, and continues to extend in a direction substantially parallel to the original extension direction of the first portion 7-33a and connects to the bent portion 7-33b. It should be noted that the first portion 7-33a after bending at the bending points 7-C1 and 7-C2 is closer to the support 7-13 than the first portion 7-33a before bending at the bending points 7-C1 and 7-C2, and the first portion 7-33a does not contact the support 7-13. Furthermore, the fixing element 7-12 and the second surface 7-33c' directly contact the carrier 7-13 to contact and movably connect the carrier 7-13 with the connecting element 7-33. Since the fixing element 7-12 penetrates the first opening 7-33a" of the first portion 7-33a and the second opening 7-33c" of the second portion 7-33c", see Figure 70 , Figure 71 and Figure 72 Therefore, when viewed along the optical axis 7-O, the first portion 7-33a and the second portion 7-33c at least partially overlap with the fixing element 7-12. It should be noted that... Figure 73 In this embodiment, the fixing element 7-12 does not protrude from the first portion 7-33a. This avoids unnecessary contact between the fixing element 7-12 and other elements of the optical element drive mechanism 7-100, and also achieves the effect of miniaturization.

[0967] Please see Figure 74 ,exist Figure 74 In the embodiment, the first portion 7-33'a of the connecting element 7-33' has a bending point 7-C1', a bending point 7-C2', and a bending point 7-C3', while the second portion 7-33'c is not straight and has a bending point 7-C4'. After extending in a direction perpendicular to the optical axis 7-O, the second portion 7-33'c contacts the support 7-13 of the movable portion 7-10, and after bending at a bending point 7-C4', it extends again in another direction perpendicular to the optical axis 7-O, maintaining contact with the support 7-13 and connecting to the bent portion 7-33'b. After the first portion 7-33'a of the connecting element 7-33 extends in a direction perpendicular to the optical axis 7-O, after bending at bending points 7-C1' and 7-C2', it continues to extend in a direction substantially parallel to the original extending direction of the first portion 7-33'a. Next, the first part 7-33'a, after bending at bend point 7-C3' at an angle substantially the same as that at bend point 7-C4' of the second part 7-33'c, continues to extend in a direction substantially parallel to the second part 7-33'c and connects to the bent portion 7-33'b. It should be noted that the first part 7-33'a after bending at bend points 7-C1' and 7-C2' is closer to the support 7-13 than the first part 7-33'a before bending at bend points 7-C1' and 7-C2', and the first part 7-33'a does not contact the support 7-13. Compared to Figure 73 The connecting element 7-33 in the embodiment, Figure 74 The connecting element 7-33' in this embodiment has a longer length, better stress distribution, and higher mechanical strength, and can further reduce the possibility of breakage upon impact. The fixing element 7-12 and the second surface 7-33'c' directly contact the bearing 7-13 to contact and movably connect the bearing 7-13 and the connecting element 7-33. Because the fixing element 7-12 penetrates the first opening 7-33'a" of the first portion 7-33'a and the second opening 7-33'c" of the second portion 7-33'c, and... Figure 70 , Figure 71 and Figure 72 (Similar to the embodiment in the middle), therefore, when viewed along the optical axis 7-O, the first portion 7-33'a and the second portion 7-33'c at least partially overlap with the fixing element 7-12. It should be noted that in... Figure 74 In this embodiment, the fixing element 7-12 does not protrude beyond the first portion 7-33'a. This avoids unnecessary contact between the fixing element 7-12 and other elements of the optical element drive mechanism 7-100, and also achieves the effect of miniaturization.

[0968] Please see Figure 75 When the displacement of each piezoelectric element 7-31 and each corresponding deformation element 7-32 in the drive assembly 7-30 is the same, the drive assembly 7-30 drives the support 7-13 of the movable part 7-10 to move relative to the fixed part 7-20 in a direction parallel to the optical axis 7-O, thereby achieving the function of translating the support 7-13 of the movable part 7-10. The dotted line represents the original position of the support 7-13. Please refer to... Figure 76 In one scenario, when the displacements of the piezoelectric element 7-31 and the deformation element 7-32 in the drive assembly 7-30 are different, the drive assembly 7-30 drives the support 7-13 of the movable part 7-10 to rotate relative to the fixed part 7-20 around the axis perpendicular to the optical axis 7-O, thereby achieving the function of rotating the support 7-13 of the movable part 7-10. The dotted line represents the original position of the support 7-13. Please refer to... Figure 77 When the displacements of the piezoelectric element 7-31 and the deformation element 7-32 of the drive assembly 7-30 are different, in another case, when the displacements of the piezoelectric element 7-31 and the deformation element 7-32 of the drive assembly 7-30 are different, the drive assembly 7-30 drives the carrier 7-13 of the movable part 7-10 to move relative to the fixed part 7-20 in a direction parallel to the optical axis 7-O and rotate around the axis perpendicular to the optical axis 7-O, thereby achieving the function of translating and rotating the carrier 7-13 of the movable part 7-10. The dotted line represents the original position of the carrier 7-13.

[0969] Please see Figure 78 Another embodiment of the optical element driving mechanism 7-120 disclosed herein includes a movable part 7-40, a fixed part 7-50, and a driving assembly 7-30. Compared to the optical element driving mechanism 7-100, the movable part 7-40 of the optical element driving mechanism 7-120 no longer has a support seat, but the movable part 7-40 also includes a photosensitive element holder 7-44, while the fixed part 7-50 of the optical element driving mechanism 7-120 no longer has a photosensitive element holder, but the fixed part 7-50 also includes a support seat 7-53. The features of the driving assembly 7-30 of the optical element driving mechanism 7-120 are the same as those of the driving assembly 7-30 of the optical element driving mechanism 7-100. The main structures, functions, and configurations of the optical element driving mechanism 7-120 that are the same as those of the optical element driving mechanism 7-100 will not be described again here. In this embodiment, optical element 7-130 is a photosensitive element disposed on photosensitive element holder 7-44, and optical element 7-135 is a general lens. That is, in this embodiment, the support 7-53 does not move relative to the fixed part 7-50, but the photosensitive element holder 7-44 of the movable part 7-40 moves relative to the fixed part 7-50 through the drive assembly 7-30, thereby driving the photosensitive element to move relative to the fixed part 7-50.

[0970] Please see Figure 79 The piezoelectric element 7-31 of the drive assembly 7-30 contacts the support 7-53 of the fixed part 7-50, while the connecting element 7-33 of the drive assembly 7-30 contacts the photosensitive element holder 7-44. That is, when the piezoelectric material of the piezoelectric element 7-31 receives an external current and deforms, driving the deformation element 7-32 to deform, the connecting element 7-33 will move along with the deformation element 7-32, thereby driving the photosensitive element holder 7-44 and the optical element 7-130 to move relative to the fixed part 7-50 along the optical axis 7-O. Similarly, each piezoelectric element 7-31 and each corresponding deformation element 7-32 of the drive assembly 7-30 can move independently to achieve the function of translating, rotating, or simultaneously rotating and translating the photosensitive element holder 7-44 of the movable part 7-40. In this way, the light entering the optical element 7-135 and reaching the optical element 7-130 can be zoomed or focused by translating, rotating, or simultaneously rotating and translating the photosensitive element holder 7-44.

[0971] Please see Figure 80 In another embodiment of the optical element driving mechanism 7-140, a movable part 7-70, a fixed part 7-80, and a driving assembly 7-30 are disclosed. Compared to the optical element driving mechanism 7-100, the movable part 7-70 of the optical element driving mechanism 7-140 no longer has a support seat, but the movable part 7-70 also includes a compression ring 7-74, and the fixed part 7-80 also includes a support seat 7-84. That is, in this embodiment, the support seat 7-84 is fixedly disposed on the fixed part 7-80. The characteristics of the driving assembly 7-30 of the optical element driving mechanism 7-140 are the same as those of the driving assembly 7-30 of the optical element driving mechanism 7-100. The main structures, functions, and configurations of the optical element driving mechanism 7-140 that are the same as those of the optical element driving mechanism 7-100 will not be described again here. In this embodiment, the optical element 7-150 is a liquid lens, and the optical element 7-155 is a general lens.

[0972] Please see Figure 81The liquid lens 7-150 is disposed on the outer frame 7-81 of the fixed part 7-80, and the compression ring 7-74 is disposed below the liquid lens 7-150. In this embodiment, the drive assembly 7-30 is disposed on the fixed part 7-80 and contacts the movable part 7-70. More specifically, the piezoelectric element 7-31 of the drive assembly 7-30 contacts the base 7-82 of the fixed part 7-80, and the connecting element 7-33 of the drive assembly 7-30 contacts the compression ring 7-74 of the movable part 7-70. When the piezoelectric material of the piezoelectric element 7-31 receives an external current and deforms, driving the deformation element 7-32 to deform, the connecting element 7-33 will move with the deformation element 7-32, thereby driving the compression ring 7-74 to move relative to the fixed part 7-80 along the optical axis 7-O, and compressing the liquid lens 7-150. Similarly, each piezoelectric element 7-31 and each corresponding deformation element 7-32 of the drive assembly 7-30 can move independently, causing the extrusion ring 7-74 to extrude the liquid lens 7-150 in different ways.

[0973] Please see Figure 82 When the deformation element 7-32 does not deform (not shown), the compression ring 7-74 does not compress the liquid lens 7-150, the liquid lens 7-150 does not deform, the curvature of the liquid lens 7-150 does not change, and the mirror centerline 7-M of the liquid lens 7-150 does not change (that is, it remains parallel to the optical axis 7-O). Please refer to [link / reference]. Figure 83 When each deformation element 7-32 produces uniform deformation (not shown), the compression ring 7-74 compresses the liquid lens 7-150 with a uniform force. The liquid lens 7-150 deforms, and its curvature changes, while the mirror centerline 7-M remains unchanged (that is, parallel to the optical axis 7-O). Please refer to [link / reference]. Figure 84 When the deformation element 7-32 produces inconsistent deformation (not shown), and the compression ring 7-74 applies inconsistent force to the liquid lens 7-150, the liquid lens 7-150 deforms, its curvature changes, and the center line 7-M of the lens surface still changes (that is, it is no longer parallel to the optical axis 7-O). Therefore, by producing different deformations through the deformation element 7-32, the compression ring 7-74 can cause different deformations in the liquid lens 7-150, thereby achieving the effects of optical focusing and optical image stabilization.

[0974] Eighth set of embodiments.

[0975] Please refer to Figures 85 to 86 , Figure 85 This is a perspective view of a reflective element driving module 8-201 according to an embodiment of the present disclosure. Figure 86 In accordance with this disclosure Figure 85 An exploded view of the reflective element driving module 8-201 in an embodiment. (See attached diagram.) Figure 85 , Figure 86 As shown, in this embodiment, the reflective element driving module 8-201 has a rectangular structure with a height of less than 10 cm, mainly including a top shell 8-210, a base 8-220, a frame 8-230, four magnets 8-240, a support 8-250, a coil 8-260, an elastic element 8-270, four suspension wires 8-274, a driving plate 8-280, a circuit board 8-290, a first magnetic field sensing element 8-292, a second magnetic field sensing element 8-294, a third magnetic field sensing element 8-296, a first reflective element 8-300, a second reflective element 8-310, a bracket 8-315, and an optical element 8-320. The reflective element driving module 8-201 reflects an incident light beam with an optical axis 8-O through its internal first reflective element 8-300 and second reflective element 8-200, and finally receives it at the optical element 8-320.

[0976] The aforementioned top shell 8-210 has a hollow structure, and it can be combined with the base 8-220 to form an outer shell 8-F of the reflective element driving module 8-201. The top shell 8-210 forms the top wall 8-210A and four side walls 8-210B of the outer shell 8-F, and the base 8-220 forms the bottom wall 8-220A of the outer shell 8-F. It should be understood that a top shell opening 8-212 and a base opening 8-222 are respectively formed on the top shell 8-210 and the base 8-220. The center of the top shell opening 8-212 corresponds to the optical axis 8-O, while the base opening 8-222 corresponds to the image sensing element (not shown) located outside the reflective element driving module 8-201. External light can enter the top shell 8-210 through the top shell opening 8-212, and then be received by the aforementioned image sensing element (not shown) after passing through the optical element 8-320 and the base opening 8-222 to generate a digital image signal.

[0977] The aforementioned frame 8-230 has an opening 8-232 and four frame edges 8-230A, wherein the frame edges 8-230A correspond to the four side walls 8-210B of the outer casing 8-F. The magnets 8-240 are elongated, and the four magnets 8-240 can be fixed to the four frame edges 8-230A. In some embodiments, the magnets 8-240 can be of other different shapes, and the four magnets 8-240 can be fixed to the four corners of the frame 8-230.

[0978] The aforementioned support 8-250 has a hollow structure and a through hole 8-252, and the aforementioned coil 8-260 is wound around the outer peripheral surface of the support 8-250. In this embodiment, the support 8-250 is movably disposed within the frame 8-230. More specifically, the support 8-250 can be suspended from the center of the frame 8-230 by a metal elastic element 8-270. When a current is applied to the aforementioned coil 8-260, it can interact with the magnetic field of the magnet 8-240 to generate an electromagnetic force that drives the support 8-250 to move relative to the frame 8-230 along the Z-axis.

[0979] It should be understood that the outer periphery of the elastic element 8-270 is connected to the frame 8-230, while its inner periphery is connected to the support 8-250, thereby allowing the support 8-250 to be suspended within the frame 8-230.

[0980] One end of the aforementioned four suspension wires 8-274 is connected to the circuit board 8-290, and the other end is connected to the elastic element 8-270, so as to suspend the frame 8-230 together with the carrier 8-250 disposed therein from the housing 8-F. The material of the aforementioned suspension wires 8-274 may include, for example, metal.

[0981] The aforementioned drive board 8-280 is, for example, a printed circuit board, which has four drive coils (not shown) inside, corresponding to the positions of the four magnets 8-240 respectively, and the drive board 8-280 can be fixed to the circuit board 8-290 by adhesive.

[0982] It should be understood that the circuit board 8-290 is provided with wiring for transmitting electrical signals to the coil 8-260 and the drive coil of the drive board 8-280, and the wiring on the circuit board 8-290 can be electrically connected to the coil 8-260 through the suspension wire 8-274 and the elastic element 8-270, thereby controlling the movement of the support 8-250 in the optical axis 8-O direction. In this embodiment, the circuit board 8-290 is embedded in the base 8-220.

[0983] In this embodiment, a first magnetic field sensing element 8-292 and a second magnetic field sensing element 8-294, electrically connected to the circuit board 8-290, are respectively mounted on different sides of the base 8-220. These elements are, for example, Hall effect sensors, magnetoresistive sensors (MR sensors), or fluxgate sensors. This allows them to sense changes in the magnetic field of the magnet 8-240 on the frame 8-230 to determine the positional offset of the frame 8-230 and the support 8-250 relative to the base 8-220 in the X and Y directions. Additionally, in this embodiment, a third magnetic field sensing element 8-296 is disposed on the support 8-250, and a sensing magnet 8-298 is disposed on the frame 8-230 to sense the displacement offset in the Z direction.

[0984] It should be noted that the aforementioned circuit board 8-290 can generate and provide electrical signals to the drive coil in the aforementioned drive board 8-280, and through the electromagnetic driving force generated between this drive coil and the magnet 8-240 on the frame 8-230, the frame 8-230 is driven to move along a direction perpendicular to the optical axis 8-O (parallel to the XY plane) to compensate for the aforementioned positional offset, thereby realizing the function of optical image stabilization (OIS).

[0985] Please refer to the following: Figure 87 , Figure 87This is a schematic diagram of the structure of a first reflecting element 8-300 and a second reflecting element 8-310 according to an embodiment of the present disclosure. The first reflecting element 8-300 is disposed to correspond to an incident light ray having an optical axis 8-O. The second reflecting element 8-310 is disposed to correspond to the light reflected by the first reflecting element 8-300 and is movable relative to the first reflecting element 8-300. The first reflecting element 8-300 has a first reflecting surface 8-301, a through hole 8-302, and a first reflecting element sidewall 8-303, the through hole having a diameter 8-d. When viewed along a direction parallel to the optical axis 8-O, the through hole 8-302 partially overlaps with the second reflecting element 8-310, and the first reflecting surface 8-301 surrounds this through hole 8-302. The first reflective element sidewall 8-303 is disposed around the first reflective surface 8-301 and extends in a direction parallel to the optical axis 8-O to block unwanted light. In other words, by setting the first reflective element sidewall 8-303, interference from light that is not parallel to the optical axis 8-O can be effectively avoided. In this embodiment, the first reflective surface 8-301 is made of glass, and the first reflective element sidewall 8-303 is made of plastic. However, the materials of the first reflective surface 8-301 and the first reflective element sidewall 8-303 are not limited to these and can be changed according to needs. For example, the material of the first reflective surface 8-301 can also be stainless steel, polycarbonate, or acrylic. In addition, a thin metal film can also be deposited on the first reflective surface 8-301.

[0986] Please refer to the following: Figure 88 , Figure 88 This is a top view of a reflective element driving module 8-201 according to an embodiment of the present disclosure. A first reflective element 8-300 and a second reflective element 8-310 are arranged along a direction parallel to the optical axis 8-O. The first reflective element 8-300 is closer to the base 8-220 than the second reflective element 8-310 (see reference). Figure 89 The second reflective element 8-310 is made of a transparent material that allows some light to pass through. The second reflective element 8-310 includes a second reflective surface 8-311 and a recess 8-312 (see reference). Figure 89The bracket 8-315 is made of a light-transmitting material, allowing partial light to pass through. The bracket 8-315 is configured to connect the support base 8-250 and the second reflective element 8-310. In this embodiment, the bracket 8-315 has multiple cantilever arms 8-315A. One end of each cantilever arm 8-315A is connected to the recess 8-312 of the second reflective element 8-310, while the other end is fixed to the support base 8-250 using an insert molding method. The cantilever arms are made of metal to stably support the second reflective element 8-310. When viewed along a direction parallel to the optical axis 8-O, the bracket 8-315 partially overlaps with the first reflective element 8-300, and the cantilever arms 8-315A are point-symmetrical about the optical axis 8-O. In this embodiment, the width of the cantilever arms 8-315A is approximately 2 mm, but it is not limited to this and can be adjusted as needed.

[0987] Please refer to the following: Figure 89 , Figure 89 for Figure 85 A cross-sectional view of the reflective element driving module 8-201 cut along line segment 8-A-8-A'. Optical element 8-320 is disposed in the through-hole 8-302 of the first reflective element 8-300 to correspond to the light reflected by the second reflective element 8-310. The diameter 8-d of the through-hole 8-302 (e.g., ...) Figure 87 The width 8-w of the optical element 8-320 is greater than that of the optical element 8-320. When viewed along a direction perpendicular to the optical axis 8-O, the upper side 8-302A and lower side 8-302B of the partially protruding through-hole 8-302 of the optical element 8-320 are visible. Furthermore, when viewed along a direction perpendicular to the optical axis 8-O, the first reflecting element 8-300 at least partially overlaps with the optical element 8-320. The optical element 8-320 has an optical element sidewall 8-321, and this optical element sidewall 8-321 has a reduction portion 8-321A in the direction toward the second reflecting element 8-310, so that the light is less obstructed during reflection. For example, if the optical element 8-320 did not have the reduction portion 8-321A, when light is incident on the first reflecting element 8-300, due to the obstruction of the optical element sidewall 8-321, some light cannot be directly reflected to the second reflecting element 8-310, resulting in a smaller amount of light that the optical element 8-320 can ultimately receive. Therefore, in this embodiment, by reducing the sidewall 8-321 of this optical element to form a reduced portion 8-321A, the probability of reflected light being blocked is reduced.

[0988] Furthermore, although in this embodiment the optical element 8-320 is fixed to the first reflective element 8-300 and cannot be moved, it is not limited to this. The optical element 8-320 can also be configured to be movable relative to the first reflective element 8-300 to further enhance the focusing function of the optical element. For example, such as Figure 90 According to the block diagram of the optical element driving module 8-400 according to an embodiment of the present disclosure, an optical element driving assembly 8-340 can be added to form an optical element driving module 8-400 with the optical element 8-320. The optical element driving assembly 8-340 is used to drive the optical element 8-320 to move relative to the first reflective element 8-300.

[0989] Refer again Figure 89 The first reflecting surface 8-301 of the first reflecting element 8-300 and the second reflecting surface 8-311 of the second reflecting element 8-310 face different directions. When viewed along a direction parallel to the optical axis 8-O, the first reflecting surface 8-301 of the first reflecting element 8-300 and the second reflecting surface 8-311 of the second reflecting element 8-310 partially overlap. Therefore, when light rays parallel to the optical axis 8-O are incident from the outside onto the first reflecting surface 8-301 of the first reflecting element 8-300, the first reflecting element 8-300 converges and reflects the light rays to the focal point, which is the position of the second reflecting element 8-310. Then, the second reflecting surface 8-311 of the second reflecting element 8-310 reflects the light rays to the optical element 8-320 for further imaging. In existing lens modules, to achieve a long focal length, the lens module often needs to be lengthened. However, through the optical path design of this embodiment, a longer focal length can be obtained with a shorter lens module.

[0990] In this embodiment, the magnet 8-240, the coil 8-260, and the drive plate 8-280 constitute a drive assembly 8-330, which can be used to drive the second reflective element 8-310 to move relative to the first reflective element 8-300. When viewed along a direction perpendicular to the optical axis 8-O, the optical element 8-320 and the drive assembly 8-330 at least partially overlap. However, the composition of the drive assembly 8-330 is not limited to this. The coil, magnet, drive plate, or other components can be added or removed as needed. As mentioned above, since the carrier 8-250 is movably disposed within the frame 8-230, and the bracket 8-315 connecting the second reflective element 8-310 is disposed on the carrier 8-250, when focusing, the position in the Z-axis direction can be determined by the third sensing element 8-296 disposed on the carrier 8-250 and the sensing magnet 8-298 disposed on the frame. The circuit board 8-290 transmits an electrical signal to apply current to the coil 8-260 on the carrier 8-250. Through interaction with the magnetic field of the magnet 8-240, an electromagnetic driving force is generated to drive the carrier 8-250 and the second reflective element 8-310 to move relative to the first reflective element 8-300 in the Z-axis direction. In other words, the drive assembly 8-330 can drive the second reflective element 8-310 to move in a direction perpendicular to the optical axis 8-O, thereby achieving the focusing effect.

[0991] If the second reflective element 8-310 deviates from the focal position, the first magnetic field sensing element 8-292 and the second magnetic field sensing element 8-294 can sense the change in the magnetic field of the magnet 8-240 on the frame 8-230 to know the positional offset of the frame 8-230 and the support 8-250 relative to the base 8-220 in the X and Y directions. The circuit board 8-290 transmits an electrical signal to the drive coil (not shown) in the drive board 8-280, and through the electromagnetic driving force generated between this drive coil and the magnet 8-240 on the frame 8-230, the frame 8-230 is driven to move in a direction perpendicular to the optical axis 8-O. That is, the drive assembly 8-330 can drive the second reflective element 8-310 to move in a direction parallel to the optical axis 8-O to compensate for the aforementioned positional offset in the X and Y directions.

[0992] The embodiments disclosed in this invention not only allow for a greater amount of light intake than existing lens modules, but also achieve the same effect without elongating the optical path to the same extent as existing lens modules, thus greatly reducing the size of the lens module and achieving miniaturization.

[0993] The ninth set of examples.

[0994] Please refer to Figures 91 to 93 , Figure 91 This is a perspective view of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure. Figure 92 This is an exploded view of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure, and Figure 93 For an optical element driving mechanism 9-100 according to an embodiment of the present disclosure along Figure 91 A cross-sectional schematic diagram of line segment 9-A-9-A'. In this embodiment, the optical element driving mechanism 9-100 includes an optical element module 9-OEM, a fixed component 9-FA, a movable component 9-MA, a driving component 9-DA, and a position sensing component 9-SA. The movable component 9-MA is an optical element 9-OE corresponding to the optical element module 9-OEM, and the movable component 9-MA is movable relative to the fixed component 9-FA. The driving component 9-DA is used to drive the movable component 9-MA to move relative to the fixed component 9-FA, and the position sensing component 9-SA is used to sense the position and movement of the movable component 9-MA relative to the fixed component 9-FA.

[0995] like Figure 92As shown, the fixing assembly 9-FA may include a top frame 9-102, a side frame 9-104, and a base 9-112. The top frame 9-102 is fixedly connected to the side frame 9-104, and the side frame 9-104 is fixedly connected to the base 9-112. The top frame 9-102 has an opening 9-1021 and four protrusions 9-1023, and the optical element module 9-OEM is fixedly disposed on these protrusions 9-1023. The side frame 9-104 and the base 9-112 may form an accommodating space 9-AS. Figure 93 The configuration accommodates the active component 9-MA and the drive component 9-DA. Additionally, the fixed component 9-FA may also include a circuit board 9-114, which is fixedly disposed on one side of the side frame 9-104.

[0996] The movable component 9-MA includes a movable member 9-108 and two elastic elements 9-106. The movable member 9-108 is movably disposed within the accommodating space 9-AS, and the elastic elements 9-106 are disposed between the side frame 9-104 and the base 9-112. Additionally, the drive component 9-DA may include a drive coil 9-DCL, a first drive magnetic element 9-MG1, and a second drive magnetic element 9-MG2.

[0997] like Figure 92 As shown, the drive coil 9-DCL is disposed in the movable member 9-108, which may have multiple grooves 9-108C located around the drive coil 9-DCL, and each groove

[0998] A connecting element 9-AD can be accommodated within 9-108C to fix the drive coil 9-DCL within the movable member 9-108. A first driving magnetic element 9-MG1 and a second driving magnetic element 9-MG2 correspond to the drive coil 9-DCL and are fixedly disposed on the fixing assembly 9-FA. Specifically, the first driving magnetic element 9-MG1 and the second driving magnetic element 9-MG2 are disposed on the side frame 9-104 and located within the accommodating space 9-AS. Furthermore, the drive coil 9-DCL is electrically connected to the circuit board 9-114 via two elastic elements 9-106, for example, through... Figure 92 The solder in the 9-SD connection circuit board 9-114.

[0999] In this embodiment, the position sensing component 9-SA includes a sensed unit 9-SAU and a sensing element 9-SE. The sensing element 9-SE is disposed on the circuit board 9-114 and corresponds to the sensed unit 9-SAU. The sensed unit 9-SAU may have a plurality of reference magnetic elements 9-RGE, which are arranged along a first direction (e.g., the Z-axis direction). The sensed unit 9-SAU and the sensing element 9-SE are arranged along an arrangement direction (X-axis direction), and the aforementioned first direction is not parallel to the aforementioned arrangement direction.

[1000] like Figure 92 and Figure 93 As shown, the optical element 9-OE is a liquid lens, and the optical element module 9-OEM also has a flow channel 9-OE1 connected to the optical element 9-OE. A light-transmitting liquid is disposed within the flow channel 9-OE1 and the optical element 9-OE. Furthermore, the optical element drive mechanism 9-100 may also include a molding member 9-101, a protrusion 9-1081 of the movable member 9-108 inserted into the molding member 9-101, and the molding member 9-101 abuts against one end of the flow channel 9-OE1 (e.g., ...). Figure 93 (Left end of the middle).

[1001] In this embodiment, the optical element 9-OE and the flow channel 9-OE1 can be thin-film structures along one or both sides of the Z-axis. When the drive coil 9-DCL is energized, it generates an electromagnetic driving force with the first drive magnetic element 9-MG1 and the second drive magnetic element 9-MG2. This electromagnetic driving force drives the movable member 9-108 to move along the Z-axis. Therefore, the movable member 9-108 and the shaping part 9-101 push the flow channel 9-OE1, causing some of the liquid in the flow channel 9-OE1 to flow towards the optical element 9-OE, thereby causing the optical element 9-OE to deform. This changes the optical properties of the optical element 9-OE, thereby achieving the effect of optical zoom.

[1002] like Figure 93 As shown, the movable member 9-108 may have a spacer structure 9-108SS (spacer element) disposed between these reference magnetic elements 9-RGE. When viewed along the first direction (Z-axis), the reference magnetic elements 9-RGE partially overlap with the spacer structure 9-108SS, and the spacer structure 9-108SS is made of a non-magnetic material, such as plastic. Furthermore, the optical element driving mechanism 9-100 may include a plurality of bonding elements 9-AD respectively disposed between the spacer structure 9-108SS and these reference magnetic elements 9-RGE, so that the reference magnetic elements 9-RGE are fixed to the movable member 9-108.

[1003] Please refer to the following: Figure 94 , Figure 94This is a schematic diagram of the active component 9-108 and the position sensing component 9-SA according to this disclosure. Figure 94 As shown, the magnetic poles (N pole, S pole) of each of these reference magnetic elements 9-RGE are arranged along the X-axis direction, which is not parallel to the aforementioned first direction (Z-axis direction), and the arrangement order of the magnetic poles of these reference magnetic elements 9-RGE is opposite to each other. Specifically, in Figure 94 In the middle, the N pole of the upper reference magnetic element 9-RGE faces the sensing element 9-SE, while the N pole of the lower reference magnetic element 9-RGE faces the moving member 9-108.

[1004] Furthermore, such as Figure 94 As shown, the driving component 9-DA of this disclosure drives the movable member 9-108 of the movable component 9-MA to move relative to the fixed component 9-FA within a range of motion 9-MRG along the aforementioned first direction (Z-axis direction). The range of motion 9-MRG can be the range of movement of a center 9-108CT of the movable member 9-108 along the Z-axis direction. In the first direction, the center distance DC of the reference magnetic elements 9-RGE is greater than the range of motion 9-MRG. Based on the above configuration, the position sensing component 9-SA can accurately sense the displacement of the movable member 9-108 along the Z-axis direction.

[1005] Please refer to Figure 95 , Figure 95 The optical element driving mechanism 9-100 of one embodiment of this disclosure is along... Figure 91 A cross-sectional view of plane 9-B. (See diagram below.) Figure 95 As shown, the drive coil 9-DCL, the first drive magnetic element 9-MG1, and the second drive magnetic element 9-MG2 are arranged along a second direction (Y-axis direction), and the drive coil 9-DCL is disposed between the first drive magnetic element 9-MG1 and the second drive magnetic element 9-MG2. It is worth noting that the shortest distance 9-Dm1 between the first drive magnetic element 9-MG1 and the drive coil 9-DCL is greater than the shortest distance 9-Dm2 between the second drive magnetic element 9-MG2 and the drive coil 9-DCL. Furthermore, the winding axis of the drive coil 9-DCL is parallel to the Y-axis direction, unlike the first direction (Z-axis direction).

[1006] The drive assembly 9-DA also includes two magnetic elements 9-130 embedded within the movable member 9-108, and the magnetic elements 9-130 correspond to the first drive magnetic element 9-MG1, for example, generating a magnetic attraction with the first drive magnetic element 9-MG1. When viewed along the first direction (Z-axis direction), the magnetic elements 9-130 are located between the first drive magnetic element 9-MG1 and the drive coil 9-DCL.

[1007] Furthermore, the first driving magnetic element 9-MG1 includes a first surface 9-MGS1, a second surface 9-MGS2, and a third surface 9-MGS3. The first surface 9-MGS1 is perpendicular to the Y-axis (second direction), the second surface 9-MGS2 is perpendicular to a third direction (X-axis direction), and the third direction is perpendicular to both the first and second directions. The third surface 9-MGS3 is not parallel to the first surface 9-MGS1 and the second surface 9-MGS2, and faces the magnetic conductive element 9-130.

[1008] like Figure 95 As shown, the line 9-CL connecting the center of the magnetic element 9-130 and the center of the first driving magnetic element 9-MG1 is not parallel to the second direction (Y-axis direction), meaning that the two magnetic elements 9-130 are disposed on both sides of the first driving magnetic element 9-MG1. Furthermore, since the magnetic elements 9-130 are embedded within the movable member 9-108, they can also move relative to the first driving magnetic element 9-MG1.

[1009] In this embodiment, as Figure 95 As shown, when viewed along the second direction (Y-axis direction), the magnetically conductive element 9-130 does not overlap with the first driving magnetic element 9-MG1, and the driving coil 9-DCL partially overlaps with the magnetically conductive element 9-130. Furthermore, when viewed along the third direction, the magnetically conductive element 9-130 is positioned between the first driving magnetic element 9-MG1 and the driving coil 9-DCL.

[1010] Furthermore, in this embodiment, the optical element driving mechanism 9-100 may also include two magnetically conductive fixing members 9-140, embedded within the side frame 9-104. A first driving magnetic element 9-MG1 is disposed between the corresponding magnetically conductive fixing member 9-140 and the driving coil 9-DCL, and a second driving magnetic element 9-MG2 is disposed between the corresponding magnetically conductive fixing member 9-140 and the driving coil 9-DCL. These magnetically conductive fixing members 9-140 are used to fix the first driving magnetic element 9-MG1 and the second driving magnetic element 9-MG2. For example, a magnetic attraction force is generated between the first driving magnetic element 9-MG1 and the corresponding magnetically conductive fixing member 9-140, so that the first driving magnetic element 9-MG1 is firmly adsorbed onto the corresponding magnetically conductive fixing member 9-140.

[1011] Please refer to Figures 96 to 98 , Figure 96 This is a perspective cross-sectional view of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure. Figure 97 This is a cross-sectional view of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure along the YZ plane, and Figure 98This is a cross-sectional view of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure along the XY plane. In this embodiment, the optical element driving mechanism 9-100 may further include a guide component 9-GA, configured to guide the movable component 9-MA to move relative to the fixed component 9-FA along a first direction, and the guide component 9-GA is disposed between the magnetically conductive element 9-130 and the first driving magnetic element 9-MG1.

[1012] In this embodiment, the guide assembly 9-GA may include two first guide grooves 9-150, two second guide grooves 9-152, a first guide channel 9-154, a second guide channel 9-156, two first intermediate elements 9-160, and two second intermediate elements 9-162. Figures 96 to 98 As shown, two first guide grooves 9-150 are arranged along the first direction (Z-axis direction), and two second guide grooves 9-152 are arranged along the first direction (Z-axis direction). These first guide grooves 9-150 and these second guide grooves 9-152 correspond to the first guide groove 9-154 and the second guide groove 9-156, respectively.

[1013] like Figure 98 As shown, the first intermediate element 9-160 and the second intermediate element 9-162 can be ball bearings. The first intermediate element 9-160 is disposed between the first guide groove 9-150 and the first guide channel 9-154, while the second intermediate element 9-162 is disposed between the second guide groove 9-152 and the second guide channel 9-156. Additionally, as... Figure 96 and Figure 97 As shown, the optical element driving mechanism 9-100 may further include a plurality of stops 9-172, 9-174 and 9-176, wherein stops 9-172 and 9-174 are disposed on both sides of the first guide groove 9-150 adjacent to the top frame 9-102, stops 9-174 and 9-176 are disposed on both sides of the first guide groove 9-150 adjacent to the base 9-112, and these stops are configured to limit the range of movement of the first intermediate elements 9-160 along the first direction (Z-axis direction).

[1014] Furthermore, such as Figure 98 As shown, when viewed along the first direction (Z-axis direction), the first guide groove 9-150 and the second guide groove 9-152 each have a V-shaped structure, corresponding to the first intermediate element 9-160 and the second intermediate element 9-162 respectively, and the first guide groove 9-154 and / or the second guide groove 9-156 have a non-V-shaped structure.

[1015] It is worth noting that, such as Figure 96As shown, the first guide groove 9-154 corresponding to the first guide groove 9-150 may have a boundary 9-1541, the extension direction (X-axis direction) of the boundary 9-1541 being perpendicular to the first direction (Z-axis direction). When viewed along the second direction (Y-axis direction), and when the movable member 9-108 of the movable assembly 9-MA is at any position within the movement range 9-MRG, the first guide groove 9-150 and the boundary 9-1541 will not overlap. That is, the first intermediate element 9-160 and the second intermediate element 9-162 will not detach from the corresponding first guide groove 9-150 and second guide groove 9-152.

[1016] In addition, such as Figure 98 As shown, since there is a magnetic attraction between the magnetically conductive element 9-130 and the first driving magnetic element 9-MG1, the movable member 9-108 will abut against the first intermediate element 9-160 and the second intermediate element 9-162, so that it is stably set in the first guide groove 9-150 and the second guide groove 9-152.

[1017] Please refer to the following: Figure 99 , Figure 99 This is a cross-sectional schematic diagram of an optical element driving mechanism 9-100 according to another embodiment of the present disclosure along the XY plane. In this embodiment, the first guide groove 9-150 and the second guide groove 9-152 are non-V-shaped structures. Specifically, the first guide groove 9-154 has two first surfaces 9-1543 and 9-1544, which are not parallel to a third direction (X-axis direction). The first guide groove 9-150 has two second surfaces 9-1501 and 9-1502, which are also not parallel to a third direction. Figure 99 As shown, the shortest distance 9-Dm3 between these first surfaces 9-1543 and 9-1544 is different from the shortest distance 9-Dm4 between these second surfaces 9-1501 and 9-1502.

[1018] Please refer to the following: Figure 100 and Figure 101 , Figure 100 This is a front view of a portion of the structure of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure, and Figure 101 This is a top view of a partial structure of an optical element driving mechanism 9-100 according to an embodiment of the present disclosure. In this embodiment, the driving coil 9-DCL has a first segment 9-SG1 and a second segment 9-SG2, the second segment 9-SG2 being perpendicular to a first direction (Z-axis direction). Figure 100 As shown, the magnetic poles of the first driving magnetic element 9-MG1 and the second driving magnetic element 9-MG2 are arranged in the same direction, for example, along the Y-axis.

[1019] In addition, such as Figure 101 As shown, the first segment 9-SG1 is disposed between the first driving magnetic element 9-MG1 and the second driving magnetic element 9-MG2, and when viewed along the second direction (Y-axis direction), the first driving magnetic element 9-MG1 and the second driving magnetic element 9-MG2 partially overlap the first segment 9-SG1.

[1020] Please refer to the following: Figure 102 , Figure 102 This is a perspective view of a portion of the structure of an optical element driving mechanism 9-100 according to another embodiment of the present disclosure. In this embodiment, the driving assembly 9-DA includes a single driving magnetic element 9-MG and two driving coils 9-DCL. The driving magnetic element 9-MG is disposed within the movable member 9-108, while the two driving coils 9-DCL are disposed within the side frame 9-104, corresponding to the driving magnetic element 9-MG. The driving magnetic element 9-MG and the two driving coils 9-DCL are arranged along a second direction (Y-axis direction).

[1021] Each drive coil 9-DCL has a first segment 9-SG1 and a second segment 9-SG2, the second segment 9-SG2 being perpendicular to the first direction (Z-axis direction), and the drive magnetic element 9-MG being disposed between these first segments 9-SG1. When viewed along the second direction, the drive magnetic element 9-MG partially overlaps these first segments 9-SG1. Furthermore, when a current 9-I flows to the drive assembly 9-DA, as... Figure 102 As shown, the currents 9-I are in opposite directions in these first segments 9-SG1.

[1022] This disclosure provides an optical element driving mechanism, comprising an optical element module 9-OEM, a driving assembly 9-DA, a movable member 9-108, and a fixed assembly 9-FA. The driving assembly 9-DA can generate an electromagnetic driving force to drive the movable member 9-108 to move relative to the fixed assembly 9-FA. The movable member 9-108 can push the flow channel 9-OE1 through the molding part 9-101, causing part of the liquid in the flow channel 9-OE1 to flow to the optical element 9-OE, thereby causing the optical element 9-OE to deform. This changes the optical properties of the optical element 9-OE, thereby achieving an optical zoom effect.

[1023] Additionally, the magnetically conductive element 9-130 can be disposed within the movable member 9-108. Because the magnetically conductive element 9-130 has a magnetic attraction with the first driving magnetic element 9-MG1 of the drive assembly 9-DA, the movable member 9-108 will abut against the first intermediate element 9-160 and the second intermediate element 9-162, thus securing it firmly within the first guide groove 9-150 and the second guide groove 9-152.

[1024] Tenth example.

[1025] Please refer to Figures 103 to 105 , Figure 103 This is a perspective view of an optical system 10-100 according to an embodiment of the present disclosure. Figure 104 This is an exploded view of an optical system 10-100 according to an embodiment of the present disclosure, and Figure 105 According to an embodiment of the present disclosure Figure 103 The optical system 10-100 is shown in cross-sectional view along line segment 10-A-10-A'. The optical system 10-100 can be an optical imaging system configured to carry and drive a first optical element 10-OE, which defines an optical axis 10-O. The optical system 10-100 can be installed in various electronic devices or portable electronic devices, such as smartphones, for users to perform image extraction functions. In this embodiment, the optical system 10-100 can be a voice coil motor (VCM) with autofocus (AF) functionality, but this disclosure is not limited thereto. In other embodiments, the optical system 10-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.

[1026] like Figure 104 As shown, in this embodiment, the optical system 10-100 may include a fixed component 10-FA, a shaping component 10-101, a movable element 10-103, a connecting component 10-CA, a movable component 10-MA, and a driving module 10-DM. The shaping component 10-101 is connected between the movable element 10-103 and the first optical element 10-OE. The movable element 10-103 is movable relative to the fixed component 10-FA, and the driving module 10-DM is configured to drive the movable element 10-103 to move relative to the fixed component 10-FA. Specifically, the movable component 10-MA is movably connected to the movable element 10-103 via the connecting component 10-CA, and the driving module 10-DM drives the movable component 10-MA to move relative to the fixed component 10-FA, thereby driving the movable element 10-103.

[1027] In this embodiment, as Figure 104 as well as Figure 105As shown, the fixing assembly 10-FA includes a housing 10-102, a frame 10-104, and a base 10-112. The housing 10-102 is fixedly connected to the base 10-112, and the frame 10-104 is also fixedly connected to the inner wall surface of the housing 10-102. The fixing assembly 10-FA may define a main axis 10-AX, which is parallel to or overlaps with the optical axis 10-O of the first optical element 10-OE when the optical system 10-100 is not activated. In addition, the movable element 10-103 has a movable element surface 10-103S facing the first optical element 10-OE.

[1028] like Figure 104 as well as Figure 105 As shown, the aforementioned housing 10-102 has a hollow structure, and a housing opening 10-1021 is formed thereon. A base opening 10-1121 is formed on the base 10-112. The center of the housing opening 10-1021 corresponds to the optical axis 10-O of the first optical element 10-OE, and the base opening 10-1121 corresponds to a photosensitive element (not shown) disposed below the base 10-112. In this embodiment, the first optical element 10-OE is fixedly disposed within the housing opening 10-1021. External light can enter the housing 10-102 through the first optical element 10-OE and, after passing through the base opening 10-1121, is received by the aforementioned photosensitive element to generate a digital image signal.

[1029] Furthermore, the housing 10-102 is disposed on the base 10-112 and may have an accommodating space 10-1023 configured to accommodate the movable element 10-103, the frame 10-104, the movable component 10-MA, the connecting component 10-CA, and the drive module 10-DM.

[1030] like Figure 104 and Figure 105 As shown, in this embodiment, the movable component 10-MA may include four movable members (first movable member 10-1081, second movable member 10-1082, third movable member 10-1083, and fourth movable member 10-1084), and the connecting component 10-CA may include four connectors (first connector 10-1051, second connector 10-1052, third connector 10-1053, and fourth connector 10-1054). The first movable member 10-1081 to the fourth movable member 10-1084 are respectively connected to the movable element 10-103 through the first connector 10-1051 to the fourth connector 10-1054.

[1031] Additionally, the optical system 10-100 may further include a first elastic element 10-106 and a second elastic element 10-110, and the base 10-112 may include four protrusions 10-1123. The outer portion (outer ring portion) of the first elastic element 10-106 is fixedly disposed on the top surface of the protrusion 10-1123, the outer portion (outer ring portion) of the second elastic element 10-110 is fixedly disposed on a plane 10-1125 of the protrusion 10-1123, and the inner portions (inner ring portions) of the first elastic element 10-106 and the second elastic element 10-110 are respectively connected to the upper and lower sides of the movable component 10-MA, so that the first movable component 10-1081 to the fourth movable component 10-1084 are suspended in the accommodating space 10-1023.

[1032] In this embodiment, the drive module 10-DM may include four drive components (first drive component 10-DA1, second drive component 10-DA2, third drive component 10-DA3, and fourth drive component 10-DA4). The first drive component 10-DA1 includes a first drive coil 10-CL1 and a first magnetic element 10-MG1, the second drive component 10-DA2 includes a second drive coil 10-CL2 and a second magnetic element 10-MG2, the third drive component 10-DA3 includes a third drive coil 10-CL3 and a third magnetic element 10-MG3, and the fourth drive component 10-DA4 includes a fourth drive coil 10-CL4 and a fourth magnetic element 10-MG4.

[1033] In this embodiment, each magnetic element has a magnetic surface. For example, such as Figure 104 As shown, the first magnetic element 10-MG1 and the second magnetic element 10-MG2 each have a first magnetic surface 10-MS1 and a second magnetic surface 10-MS2. The first magnetic surface 10-MS1 faces the first driving coil 10-CL1, and the second magnetic surface 10-MS2 faces the second driving coil 10-CL2. The first magnetic surface 10-MS1 and the second magnetic surface 10-MS2 face different directions.

[1034] In this embodiment, as Figure 104 As shown, the frame 10-104 has multiple grooves 10-1041 and a central opening 10-1043. In this embodiment, the frame 10-104 has four grooves 10-1041 configured to accommodate the aforementioned four magnetic elements, but the number of grooves 10-1041 and magnetic elements is not limited to this embodiment. The central opening 10-1043 is configured to accommodate the first drive coil 10-CL1 to the fourth drive coil 10-CL4 and the first movable member 10-1081 to the fourth movable member 10-1084.

[1035] In this embodiment, the first drive coil 10-CL1 to the fourth drive coil 10-CL4 can be wound coils, respectively disposed on the first movable member 10-1081 to the fourth movable member 10-1084. When the first drive coil 10-CL1 to the fourth drive coil 10-CL4 are energized, they can generate electromagnetic driving force with the first magnetic element 10-MG1 to the fourth magnetic element 10-MG4 respectively, so as to drive at least one of the first movable member 10-1081 to the fourth movable member 10-1084 to move relative to the base 10-112 and the frame 10-104 along the direction of the optical axis 10-O (Z-axis direction) to perform autofocus or optical image stabilization.

[1036] The drive components of the drive module 10-DM can operate individually or together. For example, the first drive component 10-DA1 is configured to drive the first movable member 10-1081 to move relative to the fixed component 10-FA, and the second drive component 10-DA2 is configured to drive the second movable member 10-1082 to move relative to the fixed component 10-FA and the first movable member 10-1081, and so on.

[1037] Furthermore, such as Figure 104 As shown, in this embodiment, the fixing component 10-FA may further include at least one circuit component 10-170, configured to be electrically connected to the drive module 10-DM via a first elastic element 10-106 or a second elastic element 10-110. The circuit component 10-170 may be implemented by insert molding, but is not limited thereto.

[1038] Next, please refer to Figures 106 to 108 , Figure 106 This is a schematic diagram showing the first optical element 10-OE according to an embodiment of the present disclosure not being pushed by the molding part 10-101. Figure 107 as well as Figure 108 This is a schematic diagram showing the first optical element 10-OE according to an embodiment of the present disclosure after being pushed by the molding part 10-101. Figure 106As shown, the first optical element 10-OE can be a liquid lens, comprising a liquid lens element 10-OE1 and a fixing member 10-OE2. The liquid lens element 10-OE1 is disposed within the fixing member 10-OE2, which has a hollow structure. The fixing member 10-OE2 has the function of protecting and supporting the liquid lens element 10-OE1. The shaping member 10-101 is disposed below the liquid lens element 10-OE1 and the fixing member 10-OE2. The bottom of the fixing member 10-OE2 can be a thin film, so the shaping member 10-101 can be used to change the shape of the liquid lens element 10-OE1.

[1039] Figure 106 This indicates that the liquid lens element 10-OE1 is not deformed and the shaping part 10-101 remains in an initial position. The liquid lens element 10-OE1 has an optical axis 10-O. When a driving current is applied to the driving coil of the driving module 10-DM, a magnetic force is generated between the driving coil and the corresponding magnetic element. The driving module 10-DM drives the movable component 10-MA through this magnetic force, so that the movable component 10-MA drives the shaping part 10-101 through the connecting component 10-CA to push the lower side of the liquid lens element 10-OE1, thereby causing the liquid lens element 10-OE1 to deform.

[1040] like Figure 104 as well as Figure 107 As shown, when the first drive component 10-DA1 and the third drive component 10-DA3 of the drive module 10-DM provide the same magnitude of thrust 10-F1 and 10-F3, the shaping part 10-101 will translate along the optical axis 10-O. At this time, the lens curvature coefficient of the liquid lens element 10-OE1 is compared with... Figure 106 The curvature of the liquid lens element 10-OE1 changes, that is, the shape of the liquid lens element 10-OE1 is altered. This changes the optical properties of the liquid lens element 10-OE1, thereby achieving the effect of optical zoom.

[1041] Similarly, see Figure 108 When the drive module 10-DM drives the molded part 10-101 to tilt, such as Figure 108 Unequal thrusts 10-F1 and 10-F3 are applied to both sides of the liquid lens element 10-OE1 by the molding part 10-101, causing the optical axis 10-O of the liquid lens element 10-OE1 to rotate and deviate from the main axis 10-AX, that is, there is an included angle 10-θ1 between the two, which changes the optical properties of the liquid lens element 10-OE1, thereby achieving the effects of optical zoom, focusing or optical image stabilization.

[1042] Please refer to Figure 109 , Figure 109This is a top view of a partial structure of an optical system 10-100 according to an embodiment of the present disclosure. When viewed along the main axis 10-AX, the first elastic element 10-106 is located at multiple corners of a polygonal housing 10-102, and multiple connectors of the connecting assembly 10-CA are evenly distributed between these corners. For example, as... Figure 109 As shown, the first elastic element 10-106 may include four conductive elements 10-1061 to 10-1064, which are respectively connected to the base 10-112 located at the four corners of the outer casing 10-102, and the second connector 10-1052 is located between the conductive elements 10-1061 and the conductive elements 10-1062.

[1043] The configuration of the first elastic element 10-106 and the connecting assembly 10-CA is not limited to this embodiment. For example, in other embodiments, when viewed along the direction of the main axis 10-AX, the four conductive elements 10-1061 to 10-1064 of the first elastic element 10-106 may be located on the four sides of the housing 10-102, while the four connectors (first connector 10-1051 to fourth connector 10-1054) of the connecting assembly 10-CA may be distributed at the four corners of the housing 10-102.

[1044] like Figure 109 As shown, the optical system 10-100 may further include multiple circuit boards 10-1141 to 10-1144, which are respectively disposed between the corresponding drive coil and the movable member. For example, circuit board 10-1141 is disposed between the first movable member 10-1081 and the first drive coil 10-CL1.

[1045] Please refer to Figure 110 , Figure 110 This is a cross-sectional view of a circuit board 10-1141 and a first movable member 10-1081 according to an embodiment of the present disclosure. In this embodiment, the circuit board 10-1141 has a plate-like structure and is disposed on the first movable member 10-1081. A first drive coil 10-CL1 can be integrated into the circuit board 10-1141, and an electronic component 10-150 can be disposed between the circuit board 10-1141 and the first movable member 10-1081. Figure 110 As shown, circuit board 10-1141 includes a coil (first drive coil 10-CL1) and a circuit wire 10-117. The first drive coil 10-CL1 is electrically connected to electronic component 10-150 through the circuit wire 10-117. When viewed along the direction of circuit board 10-1141 (e.g., the X-axis direction), the first drive coil 10-CL1 partially overlaps with the circuit wire 10-117.

[1046] In this embodiment, the circuit board 10-1141 has a multi-layer structure, for example, including a first layer 10-LY1 to a fifth layer 10-LY5, and the first drive coil 10-CL1 is disposed on the second layer 10-LY2 to the fifth layer 10-LY5. Figure 110 As shown, when viewed along a direction perpendicular to the circuit board 10-1141 (e.g., the Y-axis direction), the first drive coil 10-CL1 partially overlaps the circuit wire 10-117, and the first drive coil 10-CL1 is a first portion 10-1171 surrounding the circuit wire 10-117.

[1047] like Figure 110 As shown, a portion of the first drive coil 10-CL1 is disposed on the second layer 10-LY2, and the first portion 10-1171 of the circuit wire 10-117 is disposed on the second layer 10-LY2. Additionally, a second portion 10-1172 of the circuit wire 10-117 is disposed on the first layer 10-LY1, and when viewed along the direction of the first layer 10-LY1 (e.g., the X-axis direction), the circuit wire 10-117 does not overlap with the first drive coil 10-CL1 on the first layer 10-LY1.

[1048] Furthermore, another part of the first drive coil 10-CL1 is disposed on the third layer 10-LY3, and when viewed along the direction of the third layer 10-LY3 (X-axis direction), the first drive coil 10-CL1 does not overlap with the circuit wires 10-117 on the third layer 10-LY3.

[1049] Furthermore, the circuit board 10-1141 also includes an insulating layer 10-114Z formed between the first layer 10-LY1 and the second layer 10-LY2, and the insulating layer 10-114Z is in direct contact with the first layer 10-LY1 and the second layer 10-LY2. Specifically, the circuit board 10-1141 may include multiple insulating layers 10-114Z, and these insulating layers 10-114Z can be integrally formed and cover the circuit wires 10-117 and the first drive coil 10-CL1.

[1050] Please continue to refer to this. Figure 111 , Figure 111 This is a cross-sectional schematic diagram of an optical system 10-100 according to another embodiment of the present disclosure. In this embodiment, the molding part 10-101 of the aforementioned embodiment can be integrally formed with the first optical element 10-OE, and the first optical element 10-OE can have a first segment 10-OES1 and a second segment 10-OES2. When viewed along the direction of the main axis 10-AX, the size of the first segment 10-OES1 is larger than the size of the housing opening 10-102, and the size of the second segment 10-OES2 is smaller than the size of the housing opening 10-1021.

[1051] In this embodiment, the optical system 10-100 may further include a lens barrel 10-LB, within which a second optical element 10-LS is disposed. When viewed along the principal axis 10-AX, the effective optical area of ​​the first optical element 10-OE is greater than the effective optical area of ​​the second optical element 10-LS. That is, the light transmission portion of the first optical element 10-OE (liquid lens) is larger than the light transmission portion of the second optical element 10-LS of a conventional lens.

[1052] Furthermore, the housing 10-102 has a first top surface 10-1025 that contacts the first optical element 10-OE, and as... Figure 111 As shown, when viewed along the direction of the main axis 10-AX, the first top surface 10-1025 does not overlap with the drive module 10-DM.

[1053] like Figure 111 As shown, the housing opening 10-1021 is located on the first top surface 10-1025 of the housing 10-102 and corresponds to the main shaft 10-AX. The first top surface 10-1025 is not parallel to the main shaft 10-AX; for example, the main shaft 10-AX is perpendicular to the first top surface 10-1025. When viewed along the direction of the main shaft 10-AX, the first top surface 10-1025 at least partially overlaps with the connecting assembly 10-CA. Figure 111 As shown, when viewed along the direction of the main axis 10-AX, the first top surface 10-1025 overlaps at least with the second connector 10-1052 and the fourth connector 10-1054.

[1054] like Figure 111 As shown, the outer casing 10-102 also includes a second top surface 10-1026. Both the first top surface 10-1025 and the second top surface 10-1026 are not parallel to the main shaft 10-AX and both face away from the base 10-112. Specifically, the shortest distance 10-LM2 between the second top surface 10-1026 and the base 10-112 is less than the shortest distance 10-LM1 between the first top surface 10-1025 and the base 10-112.

[1055] Next, please refer to Figure 112 , Figure 112 This is a partial structural schematic diagram of an optical system 10-100 according to an embodiment of the present disclosure. In this embodiment, each driving component of the driving module 10-DM may further include a magnetically conductive element. Figure 112As shown, in addition to the third magnetic element 10-MG3 (driving magnet) and the third driving coil 10-CL3, the third driving component 10-DA3 of the driving module 10-DM may also include a magnetically conductive element 10-PE, and the area of ​​the magnetically conductive element 10-PE is larger than the area of ​​the third magnetic element 10-MG3.

[1056] In addition, such as Figure 112 As shown, the third magnetic element 10-MG3 may have a ramp 10-IS1, and a stop ramp 10-IS2 is formed on the frame 10-104. The stop ramp 10-IS2 is configured to block the third magnetic element 10-MG3 to prevent the third magnetic element 10-MG3 from colliding with the third drive coil 10-CL3.

[1057] Next, please refer to Figure 112 and Figure 113 , Figure 113 This is a partial structural schematic diagram of an optical system 10-100 according to an embodiment of the present disclosure from another viewpoint. Figure 112 and Figure 113 As shown, the groove 10-1041 on the frame 10-104 corresponds to the magnetic element 10-PE. Furthermore, in this embodiment, when viewed along the direction of the main axis 10-AX (Z-axis direction), the groove 10-1041 partially overlaps with the magnetic element 10-PE. That is, along the Y-axis direction, a portion of the magnetic element 10-PE is located outside the groove 10-1041.

[1058] like Figure 113 As shown, the groove 10-1041 has a first receiving portion 10-AC1 and a second receiving portion 10-AC2, and there is a gap between the first receiving portion 10-AC1 and the second receiving portion 10-AC2. In this embodiment, the first receiving portion 10-AC1 may be provided with a first bonding element 10-121, and the second receiving portion 10-AC2 may be provided with a second bonding element 10-122. The first bonding element 10-121 and the second bonding element 10-122 are configured to bond the third magnetic element 10-MG3 and the magnetic conductive element 10-PE to the frame 10-104, and the aforementioned first bonding element 10-121 and second bonding element 10-122 are made of different materials. For example, one can be a UV adhesive, and the other can be a thermosetting adhesive.

[1059] Please refer to Figure 114 as well as Figure 115 , Figure 114 An exploded view of an optical system 10-100A according to another embodiment of this disclosure, and Figure 115This is a cross-sectional view of a partial structure of an optical system 10-100A according to another embodiment of the present disclosure. The optical system 10-100A is similar to the optical system 10-100. In this embodiment, the connecting assembly 10-CA of the optical system 10-100A also includes four connectors, and each connector may have an elastic part and a rigid part.

[1060] like Figure 114 and Figure 115 As shown, the second connector 10-1052 has an elastic portion 10-1055 and a rigid portion 10-1056. The elastic portion 10-1055 may have a plate-like structure and is not parallel to the main shaft 10-AX, for example, perpendicular to the main shaft 10-AX. The rigid portion 10-1056 is connected to the elastic portion 10-1055 by an adhesive member 10-AD. The rigid portion 10-1056 is connected between the elastic portion 10-1055 and the second movable member 10-1082.

[1061] Furthermore, the second drive coil 10-CL2 is disposed on the second movable member 10-1082 of the movable component 10-MA. A receiving groove 10-RC is formed between the second drive coil 10-CL2 and the second movable member 10-1082. The optical system 10-100A also includes an electronic component 10-150 (e.g., a control unit or a sensor) disposed within the receiving groove 10-RC. Through the above design, the electronic component 10-150 can be protected from damage by impact.

[1062] Please refer to Figure 116 , Figure 116 This is a partial structural schematic diagram of an optical system 10-100A according to another embodiment of the present disclosure. Figure 116 As shown, the second movable member 10-1082 of the movable assembly 10-MA has a plane 10-108N and a curved surface 10-108C, facing the main axis 10-AX. Based on this structural design, the mechanical strength of the movable assembly 10-MA can be increased and a larger lens barrel 10-LB can be accommodated.

[1063] Please refer to Figure 117 as well as Figure 118 , Figure 117 This is a partial structural schematic diagram of an optical system 10-100A according to another embodiment of the present disclosure, and Figure 118 This is a cross-sectional schematic diagram of a portion of the structure of an optical system 10-100A according to another embodiment of the present disclosure. Figure 117 and Figure 118As shown, the second movable member 10-1082 of the movable component 10-MA has a movable component surface 10-1082T, which is movably connected to the base 10-112 via a first elastic element 10-106. Furthermore, in the direction of the main shaft 10-AX, the distance 10-DD1 between the first top surface 10-1025 and the second top surface 10-1026 of the housing 10-102 is less than the distance 10-DD2 between the movable component surface 10-1082T and the first top surface 10-1025. That is, the movable component surface 10-1082T will not contact the housing 10-102.

[1064] Furthermore, the housing 10-102 also has a side wall 10-1027 connected between the first top surface 10-1025 and the second top surface 10-1026. When viewed along the main axis 10-AX, the side wall 10-1027 partially overlaps with the second movable member 10-1082. Based on the design of the housing 10-102 of this disclosure, the purposes of protecting the movable component 10-MA, accommodating the higher lens barrel 10-LB, and miniaturization can be achieved.

[1065] This disclosure provides an optical system comprising a first optical element 10-OE, a shaping member 10-101, a movable element 10-103, a fixed assembly 10-FA, a connecting assembly 10-CA, a movable assembly 10-MA, and a drive module 10-DM. The movable element 10-103 is configured to be connected to the first optical element 10-OE via the shaping member 10-101, and the movable assembly 10-MA is connected to the movable element 10-103 via the connecting assembly 10-CA. When the drive module 10-DM is configured to drive the movable assembly 10-MA to move relative to the fixed assembly 10-FA, it can move the movable element 10-103, causing the shaping member 10-101 to press against the bottom of the first optical element 10-OE, thereby changing the optical properties of the liquid lens element 10-OE1.

[1066] In some embodiments, the magnetic element is disposed within the groove 10-1041 of the frame 10-104. A stop slope 10-IS2 may be formed on the frame 10-104. The stop slope 10-IS2 is configured to block the slope 10-IS1 on the magnetic element to prevent the magnetic element from colliding with the corresponding drive coil and causing damage to the drive coil. The groove 10-1041 may have a first receiving portion 10-AC1 and a second receiving portion 10-AC2, respectively provided with a first bonding element 10-121 and a second bonding element 10-122, so that the third magnetic element 10-MG3 and the magnetic conductive element 10-PE are bonded to the frame 10-104. The aforementioned first bonding element 10-121 and second bonding element 10-122 are made of different materials.

[1067] Eleventh embodiment.

[1068] Please refer to Figures 119 to 121 , Figure 119 This is a perspective view of an optical system 11-100 according to an embodiment of the present disclosure. Figure 120 This is an exploded view of an optical system 11-100 according to an embodiment of the present disclosure, and Figure 121 According to an embodiment of the present disclosure Figure 119 The optical system 11-100 is shown in cross-sectional view along line segment 11-A-11-A'. The optical system 11-100 can be an optical imaging system configured to carry and drive a first optical element 11-OE, which defines an optical axis 11-O. The optical system 11-100 can be installed in various electronic devices or portable electronic devices, such as smartphones, for users to perform image extraction functions. In this embodiment, the optical system 11-100 can be a voice coil motor (VCM) with autofocus (AF) functionality, but this disclosure is not limited thereto. In other embodiments, the optical system 11-100 may also have autofocus (AF) and optical image stabilization (OIS) functions.

[1069] like Figure 120 As shown, in this embodiment, the optical system 11-100 may include a fixed component 11-FA, a shaping component 11-101, a movable element 11-103, a connecting component 11-CA, a movable component 11-MA, and a driving module 11-DM. The shaping component 11-101 is connected between the movable element 11-103 and the first optical element 11-OE. The movable element 11-103 is movable relative to the fixed component 11-FA, and the driving module 11-DM is configured to drive the movable element 11-103 to move relative to the fixed component 11-FA. Specifically, the movable component 11-MA is movably connected to the movable element 11-103 via the connecting component 11-CA, and the driving module 11-DM drives the movable component 11-MA to move relative to the fixed component 11-FA, thereby driving the movable element 11-103.

[1070] In this embodiment, as Figure 120 as well as Figure 121As shown, the fixing assembly 11-FA includes a housing 11-102, a frame 11-104, and a base 11-112. The housing 11-102 is fixedly connected to the base 11-112, and the frame 11-104 is also fixedly connected to the inner wall surface of the housing 11-102. The fixing assembly 11-FA may define a main axis 11-AX, which is parallel to or overlaps with the optical axis 11-O of the first optical element 11-OE when the optical system 11-100 is not activated. In addition, the movable element 11-103 has a movable element surface 11-103S facing the first optical element 11-OE.

[1071] like Figure 120 as well as Figure 121 As shown, the aforementioned housing 11-102 has a hollow structure, and a housing opening 11-1021 is formed thereon. A base opening 11-1121 is formed on the base 11-112. The center of the housing opening 11-1021 corresponds to the optical axis 11-O of the first optical element 11-OE, and the base opening 11-1121 corresponds to a photosensitive element (not shown) disposed below the base 11-112. In this embodiment, the first optical element 11-OE is fixedly disposed within the housing opening 11-1021. External light can enter the housing 11-102 through the first optical element 11-OE and, after passing through the base opening 11-1121, is received by the aforementioned photosensitive element to generate a digital image signal.

[1072] Furthermore, the housing 11-102 is disposed on the base 11-112 and may have an accommodating space 11-1023 configured to accommodate the movable element 11-103, the frame 11-104, the movable component 11-MA, the connecting component 11-CA, and the drive module 11-DM.

[1073] like Figure 120 and Figure 121 As shown, in this embodiment, the movable component 11-MA may include four movable members (first movable member 11-1081, second movable member 11-1082, third movable member 11-1083, and fourth movable member 11-1084), and the connecting component 11-CA may include four connectors (first connector 11-1051, second connector 11-1052, third connector 11-1053, and fourth connector 11-1054). The first movable member 11-1081 to the fourth movable member 11-1084 are respectively connected to the movable element 11-103 through the first connector 11-1051 to the fourth connector 11-1054.

[1074] Additionally, the optical system 11-100 may further include a first elastic element 11-106 and a second elastic element 11-110, and the base 11-112 may include four protrusions 11-1123. The outer portion (outer ring portion) of the first elastic element 11-106 is fixedly disposed on the top surface of the protrusion 11-1123, the outer portion (outer ring portion) of the second elastic element 11-110 is fixedly disposed on a plane 11-1125 of the protrusion 11-1123, and the inner portions (inner ring portions) of the first elastic element 11-106 and the second elastic element 11-110 are respectively connected to the upper and lower sides of the movable component 11-MA, so that the first movable component 11-1081 to the fourth movable component 11-1084 are suspended in the accommodating space 11-1023.

[1075] In this embodiment, the drive module 11-DM may include four drive components (first drive component 11-DA1, second drive component 11-DA2, third drive component 11-DA3, and fourth drive component 11-DA4). The first drive component 11-DA1 includes a first drive coil 11-CL1 and a first magnetic element 11-MG1, the second drive component 11-DA2 includes a second drive coil 11-CL2 and a second magnetic element 11-MG2, the third drive component 11-DA3 includes a third drive coil 11-CL3 and a third magnetic element 11-MG3, and the fourth drive component 11-DA4 includes a fourth drive coil 11-CL4 and a fourth magnetic element 11-MG4.

[1076] In this embodiment, each magnetic element has a magnetic surface. For example, such as Figure 120 As shown, the first magnetic element 11-MG1 and the second magnetic element 11-MG2 each have a first magnetic surface 11-MS1 and a second magnetic surface 11-MS2. The first magnetic surface 11-MS1 faces the first driving coil 11-CL1, and the second magnetic surface 11-MS2 faces the second driving coil 11-CL2. The first magnetic surface 11-MS1 and the second magnetic surface 11-MS2 face different directions.

[1077] In this embodiment, as Figure 120As shown, the frame 11-104 has multiple grooves 11-1041 and a central opening 11-1043. In this embodiment, the frame 11-104 has four grooves 11-1041 configured to accommodate the aforementioned four magnetic elements, but the number of grooves 11-1041 and magnetic elements 11-MG is not limited to this embodiment. The central opening 11-1043 is configured to accommodate the first drive coil 11-CL1 to the fourth drive coil 11-CL4 and the first movable member 11-1081 to the fourth movable member 11-1084.

[1078] In this embodiment, the first drive coil 11-CL1 to the fourth drive coil 11-CL4 can be wound coils, respectively disposed on the first movable member 11-1081 to the fourth movable member 11-1084. When the first drive coil 11-CL1 to the fourth drive coil 11-CL4 are energized, they can generate electromagnetic driving force with the first magnetic element 11-MG1 to the fourth magnetic element 11-MG4 respectively, so as to drive at least one of the first movable member 11-1081 to the fourth movable member 11-1084 to move relative to the base 11-112 and the frame 11-104 along the direction of the optical axis 11-O (Z-axis direction) to perform autofocus or optical image stabilization.

[1079] The drive components of drive module 11-DM can operate individually or together. For example, the first drive component 11-DA1 is configured to drive the first movable member 11-1081 to move relative to the fixed component 11-FA, and the second drive component 11-DA2 is configured to drive the second movable member 11-1082 to move relative to the fixed component 11-FA and the first movable member 11-1081, and so on.

[1080] Furthermore, such as Figure 120 As shown, in this embodiment, the fixing component 11-FA may further include at least one circuit component 11-170, configured to be electrically connected to the drive module 11-DM via a first elastic element 11-106 or a second elastic element 11-110. The circuit component 11-170 may be implemented by insert molding, but is not limited thereto.

[1081] Next, please refer to Figures 122 to 124 , Figure 122 This is a schematic diagram showing the first optical element 11-OE according to an embodiment of the present disclosure not being pushed by the molding part 11-101. Figure 123 as well as Figure 124 This is a schematic diagram showing the first optical element 11-OE according to an embodiment of the present disclosure after being pushed by the molding part 11-101. Figure 122 As shown, the first optical element 11-OE can be a liquid lens, comprising a liquid lens element 11-OE1 and a fixing member 11-OE2. The liquid lens element 11-OE1 is disposed within the fixing member 11-OE2, which has a hollow structure. The fixing member 11-OE2 has the function of protecting and supporting the liquid lens element 11-OE1. The shaping member 11-101 is disposed below the liquid lens element 11-OE1 and the fixing member 11-OE2. The bottom of the fixing member 11-OE2 can be a thin film, so the shaping member 11-101 can be used to change the shape of the liquid lens element 11-OE1.

[1082] Figure 122 This indicates that the liquid lens element 11-OE1 is not deformed and the shaping part 11-101 remains in an initial position. The liquid lens element 11-OE1 has an optical axis 11-O. When a driving current is applied to the driving coil of the driving module 11-DM, a magnetic force is generated between the driving coil and the corresponding magnetic element. The driving module 11-DM drives the movable component 11-MA through this magnetic force, so that the movable component 11-MA drives the shaping part 11-101 through the connecting component 11-CA to push the lower side of the liquid lens element 11-OE1, thereby causing the liquid lens element 11-OE1 to deform.

[1083] like Figure 120 as well as Figure 123 As shown, when the first drive component 11-DA1 and the third drive component 11-DA3 of the drive module 11-DM provide the same magnitude of thrust 11-F1 and 11-F3, the shaping part 11-101 will translate along the optical axis 11-O. At this time, the lens curvature coefficient of the liquid lens element 11-OE1 is compared with... Figure 122 The curvature of the liquid lens element 11-OE1 changes, that is, the shape of the liquid lens element 11-OE1 is altered. This changes the optical properties of the liquid lens element 11-OE1, thereby achieving the effect of optical zoom.

[1084] Similarly, see Figure 124 When the drive module 11-DM drives the molded part 11-101 to tilt, such as Figure 124 Unequal thrusts 11-F1 and 11-F3 are applied to both sides of the liquid lens element 11-OE1 by the molding part 11-101, causing the optical axis 11-O of the liquid lens element 11-OE1 to rotate and deviate from the main axis 11-AX, that is, there is an included angle 11-θ1 between the two, which changes the optical properties of the liquid lens element 11-OE1, thereby achieving the effects of optical zoom, focusing or optical image stabilization.

[1085] Please refer to Figure 125 as well as Figure 126, Figure 125 An exploded view of an optical system 11-100A according to another embodiment of this disclosure, and Figure 126 This is a cross-sectional view of an optical system 11-100A according to another embodiment of the present disclosure. Optical system 11-100A is similar to optical system 11-100 and may include a lens barrel 11-LB. In this embodiment, the connecting assembly 11-CA of optical system 11-100A also includes four connectors, and each connector may have an elastic portion and a rigid portion.

[1086] For example, such as Figure 125 and Figure 126 As shown, the second connector 11-1052 has an elastic portion 11-1055 and a rigid portion 11-1056. The elastic portion 11-1055 may have a plate-like structure and is not parallel to the main shaft 11-AX, for example, perpendicular to the main shaft 11-AX. The rigid portion 11-1056 is connected to the elastic portion 11-1055 by an adhesive member 11-AD. The rigid portion 11-1056 is connected between the elastic portion 11-1055 and the second movable member 11-1082.

[1087] Please refer to Figure 127 , Figure 127 This is a partial structural schematic diagram of an optical system 11-100A according to another embodiment of the present disclosure. In this embodiment, the optical system 11-100A further includes a stop assembly, and the stop assembly may include multiple stop members, respectively disposed on the first movable member 11-1081 to the fourth movable member 11-1084. The aforementioned stop assembly is used to limit the range of motion of the movable member 11-MA and the movable element 11-103.

[1088] Specifically, such as Figure 127 As shown, the first movable member 11-1081 is provided with two first stop members 11-151, two second stop members 11-152, and two third stop members 11-153. These first stop members 11-151 are all located on one side of the first movable member 11-1081, facing the first optical element 11-OE, while these second stop members 11-152 are all located on the other side of the first movable member 11-1081, facing the base 11-112.

[1089] In addition, such as Figure 127 As shown, the first drive coil 11-CL1 surrounds the third stop 11-153, and the optical system 11-100A may further include at least one gel 11-GU disposed on the third stop 11-153, the gel 11-GU being configured to bond the first drive coil 11-CL1 and the first movable member 11-1081.

[1090] It should be noted that the second movable member 11-1082, the third movable member 11-1083 and the fourth movable member 11-1084 also have the same configuration, and the number of the first stop 11-151, the second stop 11-152 and the third stop 11-153 on each movable member in this disclosure is less than three.

[1091] Please continue to refer to this. Figure 127 and Figure 128 , Figure 128 This is a top view of a portion of the structure of an optical system 11-100A according to another embodiment of the present disclosure. In this embodiment, the first stops 11-151, two second stops 11-152, and two third stops 11-153 on the first movable member 11-1081 correspond only to one side wall 11-102S of the housing 11-102. That is, when viewed from the direction of the main axis 11-AX, the line connecting these first stops 11-151 does not pass through the main axis 11-AX.

[1092] Furthermore, such as Figure 127 and Figure 128 As shown, when viewed along the direction of the main shaft 11-AX, these first stops 11-151 partially overlap the first drive coil 11-CL1 of the first drive assembly 11-DA1. Similarly, the second stops 11-152 also partially overlap the first drive coil 11-CL1 of the first drive assembly 11-DA1.

[1093] In addition, such as Figure 128 As shown, in the Y-axis direction (first direction), the distance between the third stop 11-153 and the first magnetic element 11-MG1 (driving magnet) is less than the distance between the first driving coil 11-CL1 and the first magnetic element 11-MG1. That is, the third stop 11-153 can be used to prevent the first driving coil 11-CL1 from colliding with the first magnetic element 11-MG1.

[1094] Please refer to the following: Figure 129 , Figure 129 This is a cross-sectional view of an optical system 11-100A according to another embodiment of the present disclosure. Figure 129 As shown, the sidewall 11-102S includes a first top surface 11-1025 and a second top surface 11-1026, and when viewed along the main axis 11-AX, the second top surface 11-1026 partially overlaps with these first stops 11-151. In other embodiments, the second top surface 11-1026 may not overlap with the first stops 11-151.

[1095] Furthermore, when viewed along the direction of the main axis 11-AX, the first top surface 11-1025 does not overlap with the second magnetic element 11-MG2 and the second drive coil 11-CL2 of the second drive assembly 11-DA2.

[1096] Please continue to refer to this. Figure 130 , Figure 130 This is a schematic diagram of a partial structure of an optical system 11-100A according to another embodiment of the present disclosure. In this embodiment, four protruding pillars 11-1127 may be further formed on the base 11-112. Figure 125 Furthermore, the aforementioned stop assembly may further include a fourth stop 11-154 extending along the Y-axis direction (first axial direction) and disposed on the first movable member 11-1081. The protrusion 11-1127 is configured to block the fourth stop 11-154, thereby preventing the first movable member 11-1081 of the movable assembly 11-MA from rotating about the main shaft 11-AX or moving along the Y-axis direction (first axial direction) or the X-axis direction (second axial direction).

[1097] When viewed along the direction of the main axis 11-AX (Z-axis direction), the protrusion 11-1127 is located between the first drive coil 11-CL1 of the first drive assembly 11-DA1 and the main axis 11-AX. Additionally, the optical system 11-100A may also include a gel 11-GU disposed between the protrusion 11-1127 and the movable assembly 11-MA. Figure 130 As shown, gel 11-GU is disposed between the protrusion 11-1127 and the first movable member 11-1081, and gel 11-GU is also disposed between the protrusion 11-1127 and the fourth movable member 11-1084.

[1098] like Figure 130 As shown, the aforementioned stop assembly may further include a fifth stop 11-155, disposed on the first movable member 11-1081 and facing the outer casing 11-102, and a protrusion 11-1128 may be formed on the protrusion 11-1127 to block the fifth stop 11-155, thereby preventing the first movable member 11-1081 of the movable assembly 11-MA from rotating about the X-axis (second axis).

[1099] Please refer to Figure 130 and Figure 131 , Figure 131 This is a cross-sectional view along the XZ plane of an optical system 11-100A according to an embodiment of the present disclosure. Figure 131 As shown, along the direction of the main shaft 11-AX, the distance between the protrusion 11-1128 and the housing 11-102 is less than the distance between the fifth stop 11-155 and the housing 11-102.

[1100] In addition, such as Figure 131 As shown, the aforementioned stop assembly may further include a sixth stop 11-156, disposed on the first movable member 11-1081 and facing the base 11-112. The protrusion 11-1127 is configured to block the sixth stop 11-156, thereby preventing the first movable member 11-1081 of the movable assembly 11-MA from rotating about the X-axis (second axis).

[1101] In this embodiment, the sixth stop 11-156 and the fifth stop 11-155 are disposed on opposite sides of the first movable member 11-1081, and when viewed along the main axis 11-AX, the fifth stop 11-155 partially overlaps the sixth stop 11-156. That is, the shapes of the fifth stop 11-155 and the sixth stop 11-156 may be different or asymmetrical.

[1102] like Figure 130 As shown, the first movable member 11-1081 has a first surface 11-SR1 and a second surface 11-SR2, which are connected at a corner 11-CN. A first contact surface 11-CR1 of the gel 11-GU contacts the first surface 11-SR1, and a second contact surface 11-CR2 of the gel 11-GU contacts the second surface 11-SR2. The protruding post 11-1127 has a third surface 11-SR3, and a third contact surface 11-CR3 of the gel 11-GU is configured to contact the third surface 11-SR3.

[1103] Please refer to Figures 133 to 135 , Figures 133 to 135 This is a schematic diagram illustrating the movement of the first movable member 11-1081 relative to the protrusion 11-1127 according to an embodiment of the present disclosure. Figure 133 As shown, when the first movable member 11-1081 does not move relative to the protrusion 11-1127, the gel 11-GU will not deform. Next, as... Figure 134 and Figure 135 As shown, the first movable member 11-1081 of the movable component 11-MA is configurable to move along the main axis 11-AX (Z-axis direction) between an upper limit position 11-ULP and a lower limit position 11-DLP, and the gel 11-GU is disposed between the upper limit position 11-ULP and the lower limit position 11-DLP. Specifically, the gel 11-GU can be disposed at the center of the upper limit position 11-ULP and the lower limit position 11-DLP, but is not limited thereto.

[1104] Furthermore, such as Figure 134As shown, when the first active member 11-1081 of the active component 11-MA is in the upper limit position 11-ULP, the gel 11-GU deforms, and the distance D11 between the first contact surface 11-CR1 and the outer shell 11-102 along the direction of the main axis 11-AX is less than the distance D12 between the third contact surface 11-CR3 and the outer shell 11-102.

[1105] Furthermore, such as Figure 135 As shown, when the first active member 11-1081 of the active component 11-MA is in the lower limit position 11-DLP, the gel 11-GU deforms, and the distance D11 between the first contact surface 11-CR1 and the outer shell 11-102 along the direction of the main axis 11-AX is greater than the distance D12 between the third contact surface 11-CR3 and the outer shell 11-102.

[1106] Please continue to refer to this. Figure 136 , Figure 136 This is a top view schematic diagram of a portion of the structure of an optical system 11-100A according to another embodiment of the present disclosure. Figure 136 As shown, the first movable member 11-1081 is arranged along the X-axis direction (second axis), the second movable member 11-1082 is arranged along the Y-axis direction (first axis), the second movable member 11-1082 is adjacent to the first movable member 11-1081, and the second movable member 11-1082 is configured to block the first movable member 11-1081 from moving along the X-axis direction or the Y-axis direction.

[1107] Furthermore, the optical system 11-100A also includes one or more gels 11-GU, disposed between the first movable member 11-1081 and the second movable member 11-1082. For example... Figure 136 As shown, by setting gel 11-GU, damage to the first movable component 11-1081 from direct collision with the second movable component 11-1082 can be avoided.

[1108] like Figure 136 As shown, the first elastic element 11-106 includes a first string arm 11-SA1 and a second string arm 11-SA2, which are respectively connected to the first movable member 11-1081 and the second movable member 11-1082. The gel 11-GU can also be disposed between the first string arm 11-SA1 and the second string arm 11-SA2 to avoid collision between the first string arm 11-SA1 and the second string arm 11-SA2, thereby preventing damage.

[1109] Furthermore, in this embodiment, gel 11-GU may also be disposed between the elastic element and the movable component 11-MA. For example... Figure 136As shown, gel 11-GU is disposed between the first elastic element 11-106 and the second movable member 11-1082.

[1110] Please refer to Figure 137 , Figure 137 This is a partial structural schematic diagram of an optical system 11-100A according to another embodiment of the present disclosure. In this embodiment, a avoidance groove 11-1127C is formed on the protrusion 11-1127, corresponding to the first stringer arm 11-SA1 and the second stringer arm 11-SA2. By providing the avoidance groove 11-1127C, the first stringer arm 11-SA1 and the second stringer arm 11-SA2 can be prevented from directly colliding with the protrusion 11-1127 and causing damage.

[1111] Please refer to Figure 138, which is a partial structural schematic diagram of the optical system 11-100A according to another embodiment of the present disclosure. The protrusions 11-1127 of the present disclosure may have different designs. In this embodiment, the protrusions 11-1127 may be further formed into a receiving groove 11-1127R, and the optical system 11-100A may also include a bonding element 11-AE disposed in the receiving groove 11-1127R and configured to adhere to the protrusions 11-1127, the first elastic element 11-106, and the housing 11-102.

[1112] In this embodiment, the optical system 11-100A may further include another gel 11-GU disposed between the elastic element and the fixing assembly 11-FA. Specifically, as shown in Figure 138, the first elastic element 11-106 may have a perforation 11-106H, and the gel 11-GU can be disposed between the first elastic element 11-106 and the protrusion 11-1127 through the perforation 11-106H.

[1113] This disclosure provides an optical system comprising a first optical element 11-OE, a shaping member 11-101, a movable element 11-103, a fixed assembly 11-FA, a connecting assembly 11-CA, a movable assembly 11-MA, and a drive module 11-DM. The movable element 11-103 is configured to be connected to the first optical element 11-OE via the shaping member 11-101, and the movable assembly 11-MA is connected to the movable element 11-103 via the connecting assembly 11-CA. When the drive module 11-DM is configured to drive the movable assembly 11-MA to move relative to the fixed assembly 11-FA, it can move the movable element 11-103, causing the shaping member 11-101 to press against the bottom of the first optical element 11-OE, thereby changing the optical properties of the liquid lens element 11-OE1.

[1114] In addition, the optical system disclosed herein may include multiple gels 11-GU, which can serve as buffer elements and be disposed between the stop and the drive coil, between adjacent movable members, between the movable member and the protrusion 11-1127, between the elastic element and the movable assembly 11-MA, or between the elastic element and the fixed assembly 11-FA, thereby preventing damage to components in the optical system due to collisions.
