Description

Technical Field

[0001] The present disclosure relates to an optical element driving mechanism, and more particularly to an optical element driving mechanism having a long focal length and an anti-shake function. Background Art

[0002] With the development of technology, many current electronic devices (such as smart phones) have functions of taking pictures or videos. Through a camera module disposed on the electronic device, a user can operate the electronic device to capture various photos.

[0003] The current design of electronic devices is continuously trending towards miniaturization, such that various components or their structures of the camera module must also be continuously reduced to achieve the purpose of miniaturization. Generally, the driving mechanism in the camera module may have a lens carrier configured to carry a lens, and the driving mechanism may have functions of auto focusing or optical image stabilization. However, although the existing driving mechanism can achieve the aforementioned functions of taking pictures or videos, it still cannot meet all requirements.

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

[0139] The following discloses many different implementation methods or examples for implementing the provided different features. The following describes embodiments of specific components and their arrangements to illustrate the present disclosure. Of course, these embodiments are only for illustration and should not limit the scope of the present disclosure. For example, when it is mentioned in the specification that a first feature component is formed on a second feature component, it may include an embodiment where the first feature component and the second feature component are in direct contact. Additionally, it may also include an embodiment where there are other features between the first feature component and the second feature component. In other words, the first feature component and the second feature component are not in direct contact.

[0140] In addition, repeated reference numerals or labels may be used in different embodiments. These repetitions are only for simply and clearly describing the present disclosure and do not represent a specific relationship between the different embodiments and / or structures being discussed. Further, forming, connecting to, and / or coupling to another feature component above another feature component in the present disclosure may include embodiments where the feature components are formed in direct contact, and may also include embodiments where additional feature components may be formed between the above-mentioned feature components, such that the above-mentioned feature components may not be in direct contact. Additionally, spatial-related terms may be used, such as "vertical", "above", "on", "under", "bottom", and similar terms (such as "downwardly", "upwardly", etc.). These spatial-related terms are for facilitating the description of the relationship between one (or some) element or feature and another (or some) element or feature in the drawings. These spatial-related terms are intended to cover different orientations of the device including the features.

[0141] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in a commonly used dictionary, should be interpreted to have a meaning consistent with the relevant technology and the background or context of the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0142] Furthermore, ordinal numbers such as "first", "second", etc. used in the specification and claims to modify the elements of the claims do not themselves imply or represent that the claimed element has any previous ordinal number, nor do they represent the order of one claimed element and another claimed element, or the order in the manufacturing method. The use of multiple ordinal numbers is only to clearly distinguish one claimed element having a certain name from another claimed element having the same name.

[0143] In addition, in some embodiments of the present disclosure, terms related to joining and connection, such as "connect" and "interconnect", unless otherwise specifically defined, may refer to two structures being in direct contact, or may also refer to two structures not being in direct contact, with other structures disposed between these two structures. And these terms related to joining and connection may also include cases where both structures are movable, or both structures are fixed.

[0144] Please refer to Figures 1 to 3 , Figure 1 which is a three-dimensional schematic diagram of an optical element driving mechanism 100 according to an embodiment of the present disclosure, Figure 2 is an exploded view of the optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 3 is a three-dimensional view of a partial structure of the optical element driving mechanism 100 from another perspective. The optical element driving mechanism 100 can be an optical imaging module configured to carry and drive an optical element OE.

[0145] The optical element driving mechanism 100 can be installed in various electronic devices or portable electronic devices, such as being disposed in a smart phone for a user to perform an image capturing function. In this embodiment, the optical element driving mechanism 100 can be a voice coil motor (VCM) with an autofocus (AF) function, but the present disclosure is not limited thereto. In other embodiments, the optical element driving mechanism 100 can also have autofocus (AF) and optical image stabilization (OIS) functions.

[0146] As Figure 2 shown, the optical element driving mechanism 100 can include a fixed component FA, a movable component MA, and a driving component DA. The movable component MA is configured to connect the aforementioned optical element OE, and the movable component MA can move relative to the fixed component FA. The driving component DA is configured to drive the movable component MA to move relative to the fixed component FA.

[0147] In this embodiment, the fixed component FA includes a housing 102 and a base 112, and the housing 102 is fixedly connected to the base 112 along a main axis MX to form an accommodation space 1023 for accommodating the optical element OE. The housing 102 can have a first opening OP1, and when viewed along the main axis MX, the optical element OE is exposed from the first opening OP1. Among them, the optical element OE can be a reflecting prism, but is not limited thereto.

[0148] As Figure 1 and Figure 2As shown, the housing 102 further has a second opening OP2, and when viewed along a first axis AX1, the optical element OE is exposed through the second opening OP2. The first opening OP1 is in communication with the second opening OP2, and an external light ray LT enters the first opening OP1 along an optical axis OX and then enters the optical element OE. After being reflected by a reflecting surface OES of the optical element OE, it is then emitted from the optical element OE and the second opening OP2 along the first axis AX1.

[0149] In this embodiment, the movable assembly MA may include a first movable part 108 and a second movable part 109. The first movable part 108 is movably connected to the second movable part 109, and the second movable part 109 is movably connected to the base 112.

[0150] Specifically, as Figure 2 and Figure 3 shown, the optical element driving mechanism 100 may further include two first elastic elements 106 connected between the first movable part 108 and the second movable part 109. Each first elastic element 106 may have a first connection end 1061, a second connection end 1062, and a first flexible part 1063.

[0151] The first connection end 1061 is fixedly connected to the first movable part 108, the second connection end 1062 is fixedly connected to the second movable part 109, and the first flexible part 1063 is connected between the first connection end 1061 and the second connection end 1062.

[0152] Similarly, the optical element driving mechanism 100 further includes two second elastic elements 110 connected between the second movable part 109 and the base 112. Each second elastic element 110 has a third connection end 1101, a fourth connection end 1102, and a second flexible part 1103.

[0153] The third connection end 1101 is fixedly connected to the second movable part 109, the fourth connection end 1102 is fixedly connected to the base 112, and the second flexible part 1103 is connected between the third connection end 1101 and the fourth connection end 1102.

[0154] The first elastic element 106 and the second elastic element 110 may be metal elastic reeds, but are not limited thereto. Additionally, the number of the first elastic element 106 and the second elastic element 110 is not limited to this embodiment. It should be noted that the first elastic element 106 is located on a top surface TS of the movable assembly MA, while the second elastic element 110 is located on a rear side surface RS of the movable assembly MA.

[0155] Among them, as Figure 3As shown, the second connection end 1062 has a plate-like structure and is located in a first plane (such as the XY plane), and the third connection end 1101 has a plate-like structure and is located in a second plane (such as the XZ plane). In this embodiment, the first plane is not parallel to the second plane.

[0156] In addition, it should be noted that in Figure 3 , in order to clearly show the configuration of the first elastic element 106 and the second elastic element 110, the base 112 is represented by a dotted line, but it does not mean that the base 112 does not exist.

[0157] Next, please refer to Figure 2 、 Figure 4 and Figure 5 . Figure 4 FIG. is a perspective view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 5 FIG. is a perspective view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure from another perspective. As Figure 2 shown, the optical element driving mechanism 100 further includes a first strengthening member 107, which is partially embedded in the first moving part 108.

[0158] As Figure 4 shown, the first strengthening member 107 may have a strengthening base YK0 and a first strengthening structure YK1. The first strengthening structure YK1 is fixedly connected to the strengthening base YK0, and at least a part of the strengthening base YK0 and the first strengthening structure YK1 is disposed within the first moving part 108.

[0159] As Figure 4 shown, when viewed along the first axis AX1, the strengthening base YK0 is a rectangular frame structure and is embedded in the first moving part 108. Since the first strengthening member 107 can be made of a metal material, the strengthening base YK0 can enhance the overall structural strength of the first moving part 108.

[0160] Furthermore, as Figure 2 and Figure 4 shown, the driving assembly DA may include a first driving element MG1 and a first coil CL1. The first driving element MG1 is fixedly disposed at the bottom of the first moving part 108.

[0161] Correspondingly, the optical element driving mechanism 100 may further include a circuit assembly 114, and the first coil CL1 is disposed on the circuit assembly 114. The circuit assembly 114 is, for example, a flexible circuit board (FPCboard), but is not limited thereto.

[0162] In this embodiment, as Figure 4As shown, the first driving element MG1 is configured to induce the first coil CL1 to generate a first electromagnetic driving force MF1 to drive the first movable part 108 to rotate around a first rotation axis RX1 relative to the second movable part 109. For example, the first movable part 108 can make a nod (pitch) action relative to the second movable part 109 and the base 112.

[0163] like Figure 4 and Figure 5 As shown, the first driving element MG1 is disposed on the first reinforcing structure YK1 , and a portion of the first reinforcing structure YK1 is located between the first driving element MG1 and the first movable portion 108 .

[0164] It is worth noting that Figure 5 As shown, the first reinforcement structure YK1 may have a first side portion YK11, a second side portion YK12 and a third side portion YK13, which are disposed on three sides of the first driving element MG1, wherein the first side portion YK11 is adjacent to the second side portion YK12, and the second side portion YK12 is adjacent to the third side portion YK13.

[0165] Since the first reinforcement component 107 may have magnetic conductivity, the magnetic field strength of the first driving element MG1 may be increased based on the configuration of the first side portion YK11 to the third side portion YK13, and a magnetic attraction force may be generated between the first driving element MG1 and the first reinforcement structure YK1 to increase the convenience of installing the first driving element MG1 on the first reinforcement structure YK1 and the accuracy of positioning.

[0166] Furthermore, if Figure 2 and Figure 4 As shown, the optical element driving mechanism 100 may further include a first guiding element BG11 and a first guiding element BG12, which are disposed between the first movable portion 108 and the second movable portion 109 and configured to guide the first movable portion 108 to rotate around the first rotation axis RX1. Specifically, the first rotation axis RX1 is defined by the first guiding element BG11 and the first guiding element BG12, and the first rotation axis RX1 passes through the first guiding element BG11 and the first guiding element BG12.

[0167] Next, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 . Figure 6 The optical element driving mechanism 100 according to an embodiment of the present disclosure is Figure 1 A three-dimensional cross-section of the midline segment AA, and Figure 7A perspective enlarged view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure. In this embodiment, the optical element driving mechanism 100 further includes a first plate body MP1 fixedly disposed on the second movable part 109. The first plate body MP1 is, for example, a metal sheet, but is not limited thereto.

[0168] The first plate body MP1 has a first notch MP11 configured to accommodate a part of the first guiding element BG11. As Figure 6 shown, a part of the first guiding element BG11 is accommodated in the first notch MP11.

[0169] In this embodiment, the optical element driving mechanism 100 may further include a biasing element BFE disposed between the first movable part 108 and the second movable part 109. Correspondingly, as Figure 6 and Figure 7 shown, the second movable part 109 may have a first mounting groove 1091 configured to accommodate the first plate body MP1 and the first guiding element BG11. Similarly, the second movable part 109 may further have a second mounting groove 1092 configured to accommodate the biasing element BFE and the first guiding element BG12.

[0170] The first mounting groove 1091 and the second mounting groove 1092 may be grooves. Thus, as Figure 6 shown, when viewed along the main axis MX, the first plate body MP1 is exposed from the first mounting groove 1091, and when viewed along the main axis MX, the biasing element BFE is exposed from the second mounting groove 1092. Based on such a configuration, the first plate body MP1 can be conveniently and quickly mounted in the first mounting groove 1091, and the biasing element BFE can be mounted in the second mounting groove 1092.

[0171] Furthermore, as Figure 6 and Figure 7 shown, the second movable part 109 further has a recessed space 1093 communicating with the first notch MP11. The recessed space 1093 is configured to accommodate a part of the first guiding element BG11. Based on the configuration of the recessed space 1093, the first guiding element BG11 does not directly contact the second movable part 109, so as to avoid the problem that the first guiding element BG11 damages the second movable part 109 due to pushing.

[0172] Furthermore, as Figure 4 and Figure 6 shown, the first strengthening member 107 of the optical element driving mechanism 100 may further include two second strengthening structures YK2 partially disposed in the first movable part 108. The second strengthening structures YK2 are fixedly connected to the strengthening base YK0, and the strengthening base YK0 is connected between the two second strengthening structures YK2.

[0173] In this embodiment, the reinforcing base YK0, the first reinforcing structure YK1 and the second reinforcing structure YK2 may be integrally formed, but are not limited thereto. Furthermore, the first reinforcing member 107 may be a yoke, but is not limited thereto.

[0174] As Figure 4 and Figure 6 shown, each of the second reinforcing structures YK2 may have a first contact portion YK21 configured to abut against a corresponding first guiding element. Wherein, the first guiding element BG11 is clamped by the corresponding first contact portion YK21 and the first plate body MP1.

[0175] In this embodiment, the first plate body MP1 may be made of a metal material, and the first guiding element BG11 may be made of a ceramic material, but is not limited thereto. In this embodiment, the hardness of the first guiding element BG11 may be greater than the hardness of the first contact portion YK21 or the first plate body MP1. Based on such a configuration, the problem of particles generated by friction between the first guiding element BG11 and the first plate body MP1 can be avoided.

[0176] It should be noted that, in this embodiment, each of the second reinforcing structures YK2 further has a first reinforcing portion YK22 connected between the corresponding first contact portion YK21 and the reinforcing base YK0.

[0177] As Figure 6 shown, when viewed along a second axial direction AX2, the first contact portion YK21 overlaps the first reinforcing portion YK22, and the second axial direction AX2 is perpendicular to the first axial direction AX1.

[0178] Since the first movable portion 108 may be made of a plastic material, based on such a configuration, the structural strength of the side of the first movable portion 108 can be enhanced to avoid the problem that the first guiding element squeezes and damages the first movable portion 108.

[0179] In addition, as Figure 6 shown, in this embodiment, the first movable portion 108 has a first receiving opening HL1 configured to receive a part of the first guiding element BG11. Based on the configuration of the first receiving opening HL1, the first guiding element BG11 can be directly and stably fixed to the first movable portion 108 through an adhesive element (such as glue) to avoid the first guiding element BG11 falling off the first movable portion 108.

[0180] Furthermore, in this embodiment, the force applying element BFE may have a first side plate 111, an elastic body 116 and a second side plate 113, and the elastic body 116 is disposed between the first side plate 111 and the second side plate 113.

[0181] The elastomer 116 can be made of an elastic material, such as silicone, but is not limited thereto. The first side plate 111 and the second side plate 113 are made of a metal material, such as stainless steel, but are not limited thereto.

[0182] As Figure 6 shown, the first guiding element BG12 is located between the first movable part 108 and the first side plate 111. Specifically, the first side plate 111 has a positioning opening 1111 configured to accommodate at least a part of the first guiding element BG12. Correspondingly, the first movable part 108 has a second receiving opening HL2 configured to accommodate a part of the first guiding element BG12.

[0183] Among them, the size of the second receiving opening HL2 is different from the size of the positioning opening 1111. For example, the second receiving opening HL2 and the positioning opening 1111 can be circular grooves, and the size of the second receiving opening HL2 is larger than the size of the positioning opening 1111. That is, the diameter of the second receiving opening HL2 is larger than the diameter of the positioning opening 1111.

[0184] Furthermore, in this embodiment, the elastomer 116 can have a pre-pressure PF1 configured to drive the first side plate 111 to push the first guiding element BG12 so that the first guiding element BG12 abuts against the first movable part 108. The pre-pressure PF1 is the elastic restoring force of the elastomer 116. For example, when the force-applying element BFE is installed in the second movable part 109, the thickness of the force-applying element BFE in the second axial direction AX2 is less than the thickness before installation to provide the aforementioned pre-pressure PF1.

[0185] Next, please refer to Figure 8 . Figure 8 is an enlarged front view schematic diagram of the force-applying element BFE according to an embodiment of the present disclosure. In this embodiment, the first side plate 111 has a plate-like structure, and the first side plate 111 has a top side 1113 and a bottom side 1114.

[0186] As Figure 8 shown, a guiding structure 1115 can be formed on the bottom side 1114 to increase the convenience of installation. When observed along the first axial direction AX1 (Y-axis), the guiding structure 1115 can have an arc structure.

[0187] Based on such a configuration, when installing the first guiding element BG12, the guiding structure 1115 can be configured to guide the first guiding element BG12 to move into the positioning opening 1111. For example, when the first movable part 108 and the first guiding element BG12 are first positioned and then the force-applying element BFE is installed, the guiding structure 1115 can enable the force-applying element BFE to be smoothly snapped into the second installation groove 1092, and the first guiding element BG12 can also smoothly enter the positioning opening 1111.

[0188] The setting position of the guiding structure 1115 is not limited to this. In other embodiments, the guiding structure 1115 may be formed at the top side 1113, and after the force - applying element BFE is first installed in the second installation groove 1092, the first movable part 108 and the first guiding element BG12 are installed, so that the guiding structure 1115 can also guide the first guiding element BG12 to snap into the positioning port 1111.

[0189] Next, please refer to Figure 2 、 Figure 9 and Figure 10 。 Figure 9 FIG. is a perspective view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 10 FIG. is a cross - sectional view of the optical element driving mechanism 100 according to an embodiment of the present disclosure along the line B - B in Figure 1 . It should be noted that in Figure 9 , in order to clearly show the internal structure, the second movable part 109 is represented by a dotted line, but it does not mean that the second movable part 109 does not exist.

[0190] In this embodiment, the driving assembly DA may further include a second driving element MG2, a third driving element MG3, a second coil CL2, and a third coil CL3. The second driving element MG2 and the third driving element MG3 are disposed on the second movable part 109, the second coil CL2 is disposed on the base 112, and the third coil CL3 is disposed on the circuit assembly 114.

[0191] Among them, the first driving element MG1, the second driving element MG2, and the third driving element MG3 may be magnets, such as multi - pole magnets, but are not limited thereto.

[0192] As Figure 9 shown, the optical element driving mechanism 100 may further include a second strengthening member 115, which is disposed in the second movable part 109. The second strengthening member 115 may include a third strengthening structure YK3 and a fourth strengthening structure YK4, which are partially disposed in the second movable part 109. The second driving element MG2 is disposed on the third strengthening structure YK3, and a part of the third strengthening structure YK3 is located between the second driving element MG2 and the second movable part 109.

[0193] Specifically, the third strengthening structure YK3 has a fourth side portion YK31, which is disposed on one side of the second driving element MG2. The third strengthening structure YK3 may be made of a metal material and has magnetic permeability, so that the second driving element MG2 can be accurately positioned on the second movable part 109.

[0194] Similarly, the third driving element MG3 is disposed on the fourth reinforcing structure YK4, and a part of the fourth reinforcing structure YK4 is located between the third driving element MG3 and the second movable part 109. The fourth reinforcing structure YK4 has a fifth side portion YK41 disposed on one side of the third driving element MG3.

[0195] Likewise, since the fourth reinforcing structure YK4 can be made of a metallic material and has magnetic permeability, the third driving element MG3 can be accurately positioned on the second movable part 109.

[0196] As Figure 10 shown, the second movable part 109 has a first receiving groove RC1 and a second receiving groove RC2. Among them, the second driving element MG2 is received in the first receiving groove RC1 and abuts against the fourth side portion YK31, and the third driving element MG3 is received in the second receiving groove RC2 and abuts against the fifth side portion YK41.

[0197] Furthermore, the second reinforcing member 115 of the optical element driving mechanism 100 may further include a fifth reinforcing structure YK5, which is partially disposed in the second movable part 109, and the third reinforcing structure YK3 and the fourth reinforcing structure YK4 are fixedly connected to the fifth reinforcing structure YK5.

[0198] In this embodiment, the fifth reinforcing structure YK5 can be made of a metallic material, and the third reinforcing structure YK3, the fourth reinforcing structure YK4, and the fifth reinforcing structure YK5 can be integrally formed, but this is not limited thereto.

[0199] It is worth noting that, as Figure 10 shown, when viewed along the main axis MX (Z - axis), the second movable part 109 has a U - shaped structure. Therefore, based on the configuration of the fifth reinforcing structure YK5, the overall structural strength of the second movable part 109 can be increased, avoiding the problem that the middle part of the second movable part 109 is damaged due to movement or impact.

[0200] Next, as Figure 10 shown, the second driving element MG2 is configured to induce with the second coil CL2 to generate a second electromagnetic driving force MF2, and the third driving element MG3 is configured to induce with the third coil CL3 to generate a third electromagnetic driving force MF3, so that the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the first movable part 108 and the second movable part 109 to rotate relative to the base 112 about a second rotation axis RX2.

[0201] Among them, the directions of the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 are opposite. For example, when the second electromagnetic driving force MF2 is towards the -Y axis, the third electromagnetic driving force MF3 is towards the +Y axis. Therefore, the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the second movable part 109 and the first movable part 108 to rotate counterclockwise around the second rotation axis RX2.

[0202] Conversely, when the second electromagnetic driving force MF2 is towards the +Y axis, the third electromagnetic driving force MF3 is towards the -Y axis. Therefore, the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the second movable part 109 and the first movable part 108 to rotate clockwise around the second rotation axis RX2.

[0203] Among them, as Figure 9 shown, the first rotation axis RX1 is perpendicular to the second rotation axis RX2, the first rotation axis RX1 is perpendicular to the first axial direction AX1, and the second rotation axis RX2 can be parallel to the main axis MX (Z axis), but is not limited thereto.

[0204] Please refer to Figure 2 、 Figure 9 、 Figures 11 to 12 。 Figure 11 is an exploded view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 12 is an exploded view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure from another perspective. In this embodiment, the optical element driving mechanism 100 may further include a second guiding element BG21 and a second guiding element BG22, which are disposed between the second movable part 109 and the base 112 and are configured to guide the second movable part 109 and the first movable part 108 to rotate around the second rotation axis RX2.

[0205] As Figure 9 and Figure 11 shown, the second rotation axis RX2 is defined by the second guiding element BG21 and the second guiding element BG22, and the second rotation axis RX2 passes through the second guiding element BG21 and the second guiding element BG22. Furthermore, the optical element driving mechanism 100 further includes a second plate body MP2, which is fixedly disposed on the base 112.

[0206] As Figure 11 shown, when observed along the second axial direction AX2, the second guiding element BG21 and the second guiding element BG22 are located between the second movable part 109 and the second plate body MP2

[0207] As Figure 9As shown, in the direction of the second axis AX2, there is a first distance DS1 between the first guiding element BG11 and the first guiding element BG12, and in the direction of the main axis MX, there is a second distance DS2 between the second guiding element BG21 and the second guiding element BG22, and the second distance DS2 is different from the first distance DS1. In this embodiment, the second distance DS2 is less than the first distance DS1.

[0208] As Figure 11 and Figure 12 shown, the second plate body MP2 has a second notch MP21 and a third notch MP22, configured to respectively accommodate a part of the second guiding element BG21 and the second guiding element BG22.

[0209] Correspondingly, the fifth strengthening structure YK5 has a second contact portion YK51 and a third contact portion YK52, configured to respectively abut against the second guiding element BG21 and the second guiding element BG22.

[0210] Specifically, the second guiding element BG21 is clamped by the second contact portion YK51 and the second plate body MP2, and the second guiding element BG22 is clamped by the third contact portion YK52 and the second plate body MP2.

[0211] As Figure 11 shown, the base 112 has a back plate 112BP and a convex portion 112C, and the convex portion 112C protrudes from the back plate 112BP along the first axis AX1 toward the second movable portion 109. The optical element driving mechanism 100 may further include an attracting element ACE, which is fixedly disposed in the convex portion 112C. Among them, the attracting element ACE is made of a magnetic material, for example, a magnet, but is not limited thereto.

[0212] Furthermore, as Figure 11 and Figure 12 shown, the second plate body MP2 further has a fourth notch MP23, which communicates with the second notch MP21. As Figure 11 shown, when viewed along the first axis AX1, the attracting element ACE overlaps with the fourth notch MP23. Specifically, when viewed along the first axis AX1, the attracting element ACE is exposed from the fourth notch MP23.

[0213] Furthermore, as Figure 11 and Figure 12 shown, the second notch MP21 has a first limiting surface FP1 and a second limiting surface FP2, configured to limit the movement of the second guiding element BG21 along the first axis AX1 and the second axis AX2.

[0214] In this embodiment, as Figure 11As shown, when viewed along the first axial direction AX1, the first limiting surface FP1 can be parallel to the second limiting surface FP2, but is not limited thereto. The first limiting surface FP1 and the second limiting surface FP2 can be flat surfaces or arc surfaces, but are not limited thereto.

[0215] Similarly, the third notch MP22 has a third limiting surface FP3, a fourth limiting surface FP4, and a fifth limiting surface FP5, configured to limit the movement of the second guiding element BG22 along the first axial direction AX1, the second axial direction AX2, and the main axis MX.

[0216] In this embodiment, as Figure 11 shown, when viewed along the first axial direction AX1, the third limiting surface FP3 is not parallel to the fourth limiting surface FP4, and when viewed along the first axial direction AX1, the fourth limiting surface FP4 is not parallel to the fifth limiting surface FP5.

[0217] In this embodiment, as Figure 11 and Figure 12 shown, when viewed along the first axial direction AX1, the third limiting surface FP3, the fourth limiting surface FP4, and the fifth limiting surface FP5 can form a triangle, but are not limited thereto.

[0218] Next, please refer to Figure 2 , Figures 11 to 13 . Figure 13 is a cross-sectional view of the optical element driving mechanism 100 according to an embodiment of the present disclosure along the Figure 1 line segment C-C in. In this embodiment, the first movable portion 108 has a first accommodation space AS1, a part of the second movable portion 109 is located in the first accommodation space AS1, and a part of the convex portion 112C is located in the first accommodation space AS1.

[0219] Furthermore, in this embodiment, the fifth strengthening structure YK5 can be made of a magnetically conductive material, and the fifth strengthening structure YK5 can further have a bent structure YK53 located between the second contact portion YK51 and the third contact portion YK52.

[0220] As Figure 11 and Figure 12 shown, the fifth strengthening structure YK5 can further have a strengthening body YK50 connected between the third strengthening structure YK3 and the fourth strengthening structure YK4, and the bent structure YK53 is formed by bending the strengthening body YK50.

[0221] As Figure 12 shown, the bent structure YK53 is bent from the strengthening body YK50 toward the fourth notch MP23, and when viewed along the first axial direction AX1, a part of the bent structure YK53 is exposed by the second movable portion 109.

[0222] Furthermore, as Figure 13 shown, when observed along the second axis AX2, a part of the bending structure YK53 does not overlap with the second contact portion YK51 or the third contact portion YK52.

[0223] Based on such a configuration, the attracting element ACE can be configured to generate a magnetic attracting force ACF with the bending structure YK53, and the magnetic attracting force ACF is parallel to the first axis AX1. Additionally, as Figure 13 shown, the optical element driving mechanism 100 further includes a magnetic conductive element YK6 disposed in the convex portion 112C. The attracting element ACE is disposed on the magnetic conductive element YK6, and the magnetic conductive element YK6 is configured to enhance the aforementioned magnetic attracting force ACF. Similarly, the magnetic conductive element YK6 is made of a magnetic conductive material.

[0224] The magnetic attracting force ACF is configured to drive the fifth reinforcing structure YK5 to press the second movable portion 109 against the base 112, so that the fifth reinforcing structure YK5 and the second plate body MP2 jointly clamp the second guiding elements BG21 and BG22.

[0225] In this embodiment, as Figure 13 shown, when observed along the second axis AX2, a part of the second guiding element BG21 is located in the fourth notch MP23. When observed along the second axis AX2, the second notch MP21 and the fourth notch MP23 have a first length LH1.

[0226] When observed along the second axis AX2, the third notch MP22 has a second length LH2, and the first length LH1 is greater than the second length LH2. Based on such a configuration, it is possible to avoid the situation where the second guiding elements BG21 and BG22 cannot be accurately clamped between the fifth reinforcing structure YK5 and the second plate body MP2 due to tolerance problems.

[0227] In addition, it is worth noting that, as Figure 13 shown, the first movable portion 108 and the optical element OE can jointly have a center of gravity GTY, and when observed along the second axis AX2, the center of gravity GTY and the first rotation axis RX1 are on the same side of the reflection surface OES ( Figure 13 the upper left side in).

[0228] Since the center of gravity GTY is closer to the first rotation axis RX1, the moment generated by the center of gravity GTY with respect to the first rotation axis RX1 is smaller, so that the first movable portion 108 can rotate more stably around the first rotation axis RX1.

[0229] Please continue to refer to Figure 2 , Figure 10 , Figure 11 andFigure 14 。 Figure 14 This is a perspective view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure from another perspective. As Figure 10 shown, the base 112 has a first setting groove GC1 and a second setting groove GC2, configured to respectively accommodate the second coil CL2 and the third coil CL3.

[0230] Furthermore, as Figure 11 and Figure 14 shown, the optical element driving mechanism 100 further includes two conductive members 121, which are partially disposed in the base 112. Specifically, the base 112 is made of a plastic material, the two conductive members 121 are made of a metal material, and the two conductive members 121 are disposed in the base 112 by insert molding.

[0231] Next, as Figure 2 shown, the circuit assembly 114 may have a first circuit portion 1141 and a second circuit portion 1142, and the first circuit portion 1141 is connected to the second circuit portion 1142. As Figure 14 shown, in this embodiment, the circuit assembly 114 may further have two through holes 1145 and two electrical contact points 1146, and the two electrical contact points 1146 are partially disposed in the two through holes 1145. Among them, the two through holes 1145 penetrate through the first circuit portion 1141.

[0232] Correspondingly, the optical element driving mechanism 100 may further include a first reinforcing plate STP1, which is fixedly connected to the second circuit portion 1142. The first reinforcing plate STP1 may be made of a metal material, configured to strengthen the structural strength of the second circuit portion 1142.

[0233] Similarly, as Figure 2 and Figure 13 shown, the optical element driving mechanism 100 may further include a second reinforcing plate STP2, which is disposed at the bottom of the base 112, and the first circuit portion 1141 is disposed on the second reinforcing plate STP2.

[0234] It should be noted that the two through holes 1145 also penetrate through the second reinforcing plate STP2. Therefore, as Figure 14 shown, when observing along the main axis MX, the two electrical contact points 1146 are exposed from the two through holes 1145.

[0235] Furthermore, as Figure 11 and Figure 14As shown, the two conductive components 121 can be electrically connected to the second coil CL2 and fixedly connected to the two electrical contacts 1146. Specifically, the two conductive components 121 are fixedly connected to the two electrical contacts 1146 by welding. Based on the configuration of the through-holes 1145, it is convenient for the operator to quickly weld the conductive components 121 to the electrical contacts 1146, so that the second coil CL2 is electrically connected to the circuit assembly 114.

[0236] Please refer to Figure 15 . Figure 15 FIG. 1 is a top view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure. In order to ensure the stability of the first movable portion 108 and the second movable portion 109 during movement, and to prevent the first movable portion 108 or the second movable portion 109 from hitting the base 112 when the optical element driving mechanism 100 is impacted, the optical element driving mechanism 100 may further include two adhesive elements GEL1 disposed between the second movable portion 109 and the base 112.

[0237] In this embodiment, the adhesive element GEL1 may have an elastic material, such as gel, but not limited thereto. It should be noted that the adhesive element GEL1 is not disposed between the first movable portion 108 and the second movable portion 109 .

[0238] In addition, if Figure 15 As shown, the two bonding elements GEL1 of this embodiment are bilaterally symmetrical, for example symmetrical about the first axial direction AX1 (central axis), and the optical element OE is located between the two bonding elements GEL1. Based on such a configuration, the stability of the first movable part 108 and the second movable part 109 during movement can be increased.

[0239] In addition, if Figure 15 As shown, when viewed along the main axis MX, the first connection end 1061 is located between the corresponding first guide element BG12 and the second connection end 1062. When the first movable portion 108 moves relative to the second movable portion 109, the elastic restoring force of the first elastic element 106 is applied to the first movable portion 108 via the first connection end 1061. Since the first connection end 1061 is closer to the first rotation axis RX1, the torque generated by the elastic restoring force relative to the first rotation axis RX1 is smaller, so the first movable portion 108 can be more stable when rotating around the first rotation axis RX1.

[0240] The present disclosure provides an optical element driving mechanism 100, which can be a periscope lens mechanism, including a fixed component FA, a movable component MA, and a driving component DA. The movable component MA includes a first movable portion 108 and a second movable portion 109. The first movable portion 108 is movably connected to the second movable portion 109 through a first elastic element 106, and the second movable portion 109 is movably connected to the base 112 of the fixed component FA through a second elastic element 110.

[0241] The optical element driving mechanism 100 may further include a first guiding element BG11 and a first guiding element BG12, which are disposed between the first movable portion 108 and the second movable portion 109. The optical element driving mechanism 100 may further include a force applying element BFE, which is disposed between the first movable portion 108 and the second movable portion 109. The force applying element BFE may have a first side plate 111, an elastic body 116, and a second side plate 113. The elastic body 116 is disposed between the first side plate 111 and the second side plate 113. The elastic body 116 may be made of an elastic material, and the first side plate 111 and the second side plate 113 are made of a metal material.

[0242] The elastic body 116 may have a pre-pressure PF1, which is configured to drive the first side plate 111 to push against the first guiding element BG12, so that the first guiding element BG12 abuts against the first movable portion 108. The pre-pressure PF1 is the elastic restoring force of the elastic body 116. Based on such a configuration, the first guiding element BG11 and the first guiding element BG12 can be surely positioned between the first movable portion 108 and the second movable portion 109, so that the first movable portion 108 can stably rotate relative to the second movable portion 109 about the first rotation axis RX1.

[0243] Although the embodiments of the present disclosure and their advantages have been disclosed above, it should be understood that those skilled in the art can make changes, substitutions, and modifications without departing from the spirit and scope of the present disclosure.
