[0152] Reference is made to Figures 1 to 3 , Figure 1 FIG. 1 is a perspective view of an optical element driving mechanism 100 according to an embodiment of the present disclosure, Figure 2 FIG. 2 is an exploded view of the optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 3 FIG. 3 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 viewing angle. The optical element driving mechanism 100 can be an optical camera module configured to carry and drive an optical element OE.
[0153] The optical element driving mechanism 100 can be mounted on various electronic devices or portable electronic devices, such as a smart phone, for a user to perform image extraction functions. In this embodiment, the optical element driving mechanism 100 can be a voice coil motor (VCM) with an auto focus (AF) function, but the present disclosure is not limited thereto. In other embodiments, the optical element driving mechanism 100 can also have an auto focus (AF) and optical image stabilization (OIS) function.
[0154] As shown in Figure 2 , the optical element driving mechanism 100 can include a fixed assembly FA, a movable assembly MA, and a driving assembly DA. The movable assembly MA is configured to connect the aforementioned optical element OE, and the movable assembly MA can move relative to the fixed assembly FA. The driving assembly DA is configured to drive the movable assembly MA to move relative to the fixed assembly FA.
[0155] In this embodiment, the fixed assembly 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 a receiving space 1023, thereby accommodating the optical element OE. The housing 102 can have a first opening OP1, and the optical element OE is exposed from the first opening OP1 when viewed along the main axis MX. The optical element OE can be a reflective prism, but is not limited thereto.
[0156] As shown in Figure 1 and Figure 2As shown, the housing 102 also 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 connected to the second opening OP2, and an external ray LT enters the optical element OE along an optical axis OX after entering the first opening OP1, is then reflected by a reflective surface OES of the optical element OE, and then exits along the first axis AX1 from the optical element OE and the second opening OP2.
[0157] In this embodiment, the active component MA may include a first active part 108 and a second active part 109, wherein the first active part 108 is movably connected to the second active part 109, and the second active part 109 is movably connected to the base 112.
[0158] Specifically, such as Figure 2 and Figure 3 As 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 connecting end 1061, a second connecting end 1062, and a first flexible part 1063.
[0159] The first connecting end 1061 is fixedly connected to the first movable part 108, the second connecting end 1062 is fixedly connected to the second movable part 109, and the first flexible part 1063 is connected between the first connecting end 1061 and the second connecting end 1062.
[0160] Similarly, the optical element driving mechanism 100 also 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 connecting end 1101, a fourth connecting end 1102 and a second flexible part 1103.
[0161] The third connecting end 1101 is fixedly connected to the second movable part 109, the fourth connecting end 1102 is fixedly connected to the base 112, and the second flexible part 1103 is connected between the third connecting end 1101 and the fourth connecting end 1102.
[0162] The first elastic element 106 and the second elastic element 110 may be metal elastic springs, but are not limited thereto. Furthermore, the number of the first elastic element 106 and the second elastic element 110 is not limited to this embodiment. It is worth noting that the first elastic element 106 is located on a top surface TS of the movable component MA, while the second elastic element 110 is located on a rear side surface RS of the movable component MA.
[0163] Among them, such as Figure 3As shown, the second connecting end 1062 has a plate-like structure and is located in a first plane (e.g., XY plane), and the third connecting end 1101 has a plate-like structure and is located in a second plane (e.g., XZ plane). In this embodiment, the first plane is not parallel to the second plane.
[0164] In addition, it is to 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 shown in dashed lines, but it does not mean that the base 112 does not exist.
[0165] Next, please refer to Figure 2 , Figure 4 and Figure 5 . Figure 4 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 5 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 viewing angle. As Figure 2 shown, the optical element driving mechanism 100 further includes a first reinforcing component 107, which is partially embedded in the first movable portion 108.
[0166] As Figure 4 shown, the first reinforcing component 107 can have a reinforcing base YK0 and a first reinforcing structure YK1, the first reinforcing structure YK1 is fixedly connected to the reinforcing base YK0, and at least a part of the reinforcing base YK0 and the first reinforcing structure YK1 is arranged in the first movable portion 108.
[0167] As Figure 4 shown, when viewed along the first axial direction AX1, the reinforcing base YK0 is a rectangular frame structure embedded in the first movable portion 108. Since the first reinforcing component 107 can be made of metal material, the reinforcing base YK0 can enhance the overall structural strength of the first movable portion 108.
[0168] Further, as Figure 2 and Figure 4 shown, the driving assembly DA can include a first driving element MG1 and a first coil CL1, the first driving element MG1 is fixedly arranged at the bottom of the first movable portion 108.
[0169] Correspondingly, the optical element driving mechanism 100 can further include a circuit assembly 114, and the first coil CL1 is arranged on the circuit assembly 114. The circuit assembly 114 is, for example, a flexible circuit board (FPC board), but is not limited thereto.
[0170] In this embodiment, as Figure 4As shown, the first driving element MG1 is configured to generate a first electromagnetic driving force MF1 by induction with the first coil CL1, thereby driving the first movable part 108 to rotate about a first rotating shaft RX1 relative to the second movable part 109. For example, the first movable part 108 can make a pitching motion relative to the second movable part 109 and the base 112.
[0171] 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 part 108.
[0172] It is worth noting that, such as Figure 5 As shown, the first reinforcing structure YK1 may have a first side portion YK11, a second side portion YK12, and a third side portion YK13, disposed on the three sides of the first driving element MG1. 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.
[0173] Since the first reinforcing member 107 may be magnetically conductive, the magnetic field strength of the first driving element MG1 can be increased based on the configuration of the first side YK11 to the third side YK13, and a magnetic attraction force can be generated between the first driving element MG1 and the first reinforcing structure YK1 to increase the convenience of mounting the first driving element MG1 on the first reinforcing structure YK1 and the accuracy of its positioning.
[0174] Furthermore, such as 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, disposed between the first movable part 108 and the second movable part 109, configured to guide the first movable part 108 to rotate around the first rotating axis RX1. Specifically, the first rotating axis RX1 is defined by the first guiding element BG11 and the first guiding element BG12, and the first rotating axis RX1 passes through the first guiding element BG11 and the first guiding element BG12.
[0175] Next, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 . Figure 6 For an optical element driving mechanism 100 according to an embodiment of the present disclosure along Figure 1 A three-dimensional cross-sectional view of the midline segment AA, and Figure 7FIG. 7 is a perspective view of a partial structure of an 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 MP1 fixedly disposed in the second movable portion 109. The first plate MP1 is, for example, a metal plate, but is not limited thereto.
[0176] The first plate MP1 has a first notch MP11 configured to accommodate a portion of the first guide element BG11. As shown in FIG. 7, a portion of the first guide element BG11 is accommodated in the first notch MP11. Figure 6
[0177] In this embodiment, the optical element driving mechanism 100 can further include a force applying element BFE disposed between the first movable portion 108 and the second movable portion 109. Correspondingly, as shown in FIG. 8, the second movable portion 109 can have a first mounting groove 1091 configured to accommodate the first plate MP1 and the first guide element BG11. Similarly, the second movable portion 109 can further have a second mounting groove 1092 configured to accommodate the force applying element BFE and the first guide element BG12. Figure 6 Figure 7
[0178] The first mounting groove 1091 and the second mounting groove 1092 can be grooves, so as shown in FIG. 8, the first plate MP1 is exposed from the first mounting groove 1091 when viewed along the main axis MX, and the force applying element BFE is exposed from the second mounting groove 1092 when viewed along the main axis MX. Based on such a configuration, the first plate MP1 can be conveniently and quickly mounted in the first mounting groove 1091, and the force applying element BFE can be conveniently and quickly mounted in the second mounting groove 1092. Figure 6
[0179] Further, as shown in FIG. 9, the second movable portion 109 further has a recessed space 1093 communicated with the first notch MP11. The recessed space 1093 is configured to accommodate a portion of the first guide element BG11. Based on the configuration of the recessed space 1093, the first guide element BG11 does not directly contact the second movable portion 109, so as to avoid the problem that the first guide element BG11 damages the second movable portion 109 due to pushing. Figure 6 Figure 7 Further, as shown in FIG. 10, the first reinforcing component 107 of the optical element driving mechanism 100 can further include two second reinforcing structures YK2 partially disposed in the first movable portion 108. The second reinforcing structures YK2 are fixedly connected to the reinforcing base YK0, and the reinforcing base YK0 is connected between the two second reinforcing structures YK2.
[0180] Figure 4 Figure 6
[0181] 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 component 107 may be a yoke, but is not limited thereto.
[0182] like Figure 4 and Figure 6 As shown, each of the second reinforcing structures YK2 may have a first contact portion YK21, configured to abut against a corresponding first guiding element. The first guiding element BG11 is held by the corresponding first contact portion YK21 and the first plate MP1.
[0183] In this embodiment, the first plate MP1 may be made of metal, and the first guiding element BG11 may be made of ceramic, 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 MP1. Based on this configuration, the problem of particles being generated by friction between the first guiding element BG11 and the first plate MP1 can be avoided.
[0184] It is worth noting that, in this embodiment, each of the second reinforcing structures YK2 also has a first reinforcing part YK22, which is connected between the corresponding first contact part YK21 and the reinforcing base YK0.
[0185] like Figure 6 As shown, when viewed along a second axis AX2, the first contact portion YK21 overlaps the first reinforcing portion YK22, and the second axis AX2 is perpendicular to the first axis AX1.
[0186] Since the first movable part 108 can be made of plastic, this configuration can enhance the structural strength of the side of the first movable part 108, thereby avoiding the problem of the first movable part 108 being damaged by the first guide element.
[0187] In addition, such as Figure 6 As shown, in this embodiment, the first movable part 108 has a first receiving port HL1 configured to receive a portion of the first guiding element BG11. Based on the configuration of the first receiving port HL1, the first guiding element BG11 can be stably fixed to the first movable part 108 directly by a bonding element (e.g., adhesive) to prevent the first guiding element BG11 from falling off the first movable part 108.
[0188] 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, wherein the elastic body 116 is disposed between the first side plate 111 and the second side plate 113.
[0189] The elastic body 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.
[0190] As shown in Figure 6 , the first guide element BG12 is located between the first movable portion 108 and the first side plate 111. Specifically, the first side plate 111 has a positioning opening 1111 configured to accommodate at least a portion of the first guide element BG12. Correspondingly, the first movable portion 108 has a second accommodating opening HL2 configured to accommodate a portion of the first guide element BG12.
[0191] In this embodiment, the size of the second accommodating opening HL2 is different from the size of the positioning opening 1111. For example, the second accommodating opening HL2 and the positioning opening 1111 can be circular grooves, and the size of the second accommodating opening HL2 is greater than the size of the positioning opening 1111. That is, the diameter of the second accommodating opening HL2 is greater than the diameter of the positioning opening 1111.
[0192] Further, in this embodiment, the elastic body 116 can have a pre-pressure PF1 configured to drive the first side plate 111 to push the first guide element BG12 so that the first guide element BG12 abuts against the first movable portion 108. The pre-pressure PF1 is the elastic restoring force of the elastic body 116. For example, when the force applying element BFE is installed in the second movable portion 109, the thickness of the force applying element BFE in the second axial direction AX2 is less than the thickness before installation, so as to provide the aforementioned pre-pressure PF1.
[0193] Next, please refer to Figure 8 . Figure 8 is an enlarged schematic view 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 structure, and the first side plate 111 has a top side 1113 and a bottom side 1114.
[0194] As shown in Figure 8 , a guide structure 1115 can be formed on the bottom side 1114 to increase the convenience of installation. When viewed along the first axial direction AX1 (Y-axis), the guide structure 1115 can have a circular arc structure.
[0195] Based on such a configuration, when the first guide element BG12 is installed, the guide structure 1115 can be configured to guide the first guide element BG12 to move into the positioning opening 1111. For example, when the first movable portion 108 and the first guide element BG12 are positioned first, and then the force applying element BFE is installed, the guide structure 1115 can make the force applying element BFE smoothly enter the second installation groove 1092, and the first guide element BG12 can also smoothly enter the positioning opening 1111.
[0196] The location of the guide structure 1115 is not limited to this. In other embodiments, the guide structure 1115 may be formed at the top side 1113, and the force-applying element BFE may be installed into the second mounting groove 1092 first, and then the first movable part 108 and the first guide element BG12 may be installed, so that the guide structure 1115 can also guide the first guide element BG12 to be inserted into the positioning port 1111.
[0197] Please refer to the following: Figure 2 , Figure 9 and Figure 10 . Figure 9 This is a perspective view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 10 For an optical element driving mechanism 100 according to an embodiment of the present disclosure along Figure 1 A cross-sectional view of the midline segment BB. It should be noted that... Figure 9 In order to clearly show the internal structure, the second active part 109 is represented by a dashed line, but this does not mean that the second active part 109 does not exist.
[0198] In this embodiment, the driving component 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 component 114.
[0199] Among them, the first driving element MG1, the second driving element MG2 and the third driving element MG3 can be magnets, such as multi-pole magnets, but are not limited to them.
[0200] like Figure 9 As shown, the optical element driving mechanism 100 may further include a second reinforcing member 115 disposed in the second movable portion 109. The second reinforcing member 115 may include a third reinforcing structure YK3 and a fourth reinforcing structure YK4, partially disposed in the second movable portion 109. The second driving element MG2 is disposed on the third reinforcing structure YK3, and a portion of the third reinforcing structure YK3 is located between the second driving element MG2 and the second movable portion 109.
[0201] Specifically, the third reinforcing structure YK3 has a fourth side YK31, which is disposed on one side of the second driving element MG2. The third reinforcing structure YK3 can be made of metal and has magnetic conductivity, thus ensuring that the second driving element MG2 is reliably positioned on the second movable part 109.
[0202] Similarly, the third drive element MG3 is disposed on the fourth reinforcing structure YK4, and a portion of the fourth reinforcing structure YK4 is located between the third drive 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 drive element MG3.
[0203] Similarly, since the fourth reinforcing structure YK4 can be made of metal and has magnetic conductivity, the third driving element MG3 can be reliably positioned on the second moving part 109.
[0204] like Figure 10 As shown, the second movable part 109 has a first receiving groove RC1 and a second receiving groove RC2. The second driving element MG2 is received in the first receiving groove RC1 and abuts against the fourth side part YK31, and the third driving element MG3 is received in the second receiving groove RC2 and abuts against the fifth side part YK41.
[0205] Furthermore, the second reinforcing component 115 of the optical element driving mechanism 100 may also 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.
[0206] In this embodiment, the fifth reinforcing structure YK5 may be made of metal, and the third reinforcing structure YK3, the fourth reinforcing structure YK4 and the fifth reinforcing structure YK5 may be integrally formed, but are not limited thereto.
[0207] It is worth noting that, such as Figure 10 As 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 of damage to the middle part of the second movable part 109 due to movement or impact.
[0208] Next, as Figure 10 As shown, the second driving element MG2 is configured to generate a second electromagnetic driving force MF2 by induction with the second coil CL2, and the third driving element MG3 is configured to generate a third electromagnetic driving force MF3 by induction with the third coil CL3, 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 rotating shaft RX2.
[0209] Wherein, the direction of the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 is opposite. For example, when the second electromagnetic driving force MF2 is towards -Y axis, the third electromagnetic driving force MF3 is towards +Y axis, thus 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.
[0210] On the contrary, when the second electromagnetic driving force MF2 is towards +Y axis, the third electromagnetic driving force MF3 is towards -Y axis, thus 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.
[0211] Wherein, as shown in Figure 9 , 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 is parallel to the main axis MX (Z axis), but not limited thereto.
[0212] Please refer to Figure 2 , Figure 9 , Figures 11 to 12 . Figure 11 is an exploded view of part of the optical element driving mechanism 100 according to an embodiment of the present disclosure, and Figure 12 is an exploded view of part 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 can further include a second guide element BG21 and a second guide element BG22, which are arranged between the second movable part 109 and the base 112 and are configured to guide the rotation of the second movable part 109 and the first movable part 108 around the second rotation axis RX2.
[0213] As shown in Figure 9 and Figure 11 , the second rotation axis RX2 is defined by the second guide element BG21 and the second guide element BG22, and the second rotation axis RX2 passes through the second guide element BG21 and the second guide element BG22. Furthermore, the optical element driving mechanism 100 further includes a second plate body MP2 fixedly arranged on the base 112.
[0214] As shown in Figure 11 , when viewed along the second axial direction AX2, the second guide element BG21 and the second guide element BG22 are located between the second movable part 109 and the second plate body MP2
[0215] As shown in Figure 9As shown, in the direction of the second axis AX2, there is a first distance DS1 between the first guide element BG11 and the first guide element BG12, and in the direction of the main axis MX, there is a second distance DS2 between the second guide element BG21 and the second guide element BG22, and the second distance DS2 is different from the first distance DS1. In this embodiment, the second distance DS2 is smaller than the first distance DS1.
[0216] like Figure 11 and Figure 12 As shown, the second plate MP2 has a second notch MP21 and a third notch MP22, configured to accommodate a portion of the second guide element BG21 and the second guide element BG22, respectively.
[0217] Correspondingly, the fifth reinforcing structure YK5 has a second contact portion YK51 and a third contact portion YK52, which are configured to abut against the second guiding element BG21 and the second guiding element BG22 respectively.
[0218] Specifically, the second guide element BG21 is held by the second contact part YK51 and the second plate MP2, and the second guide element BG22 is held by the third contact part YK52 and the second plate MP2.
[0219] like Figure 11 As shown, the base 112 has a back plate 112BP and a protrusion 112C, and the protrusion 112C protrudes from the back plate 112BP along the first axial direction AX1 toward the second movable part 109. The optical element driving mechanism 100 may also include an attraction element ACE, which is fixedly disposed in the protrusion 112C. The attraction element ACE is made of a magnetic material, such as a magnet, but is not limited thereto.
[0220] Furthermore, such as Figure 11 and Figure 12 As shown, the second plate MP2 also has a fourth notch MP23, which connects to the second notch MP21. Figure 11 As shown, when viewed along the first axis AX1, the suction element ACE overlaps with the fourth notch MP23. Specifically, when viewed along the first axis AX1, the suction element ACE is exposed through the fourth notch MP23.
[0221] Furthermore, such as Figure 11 and Figure 12 As 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 guide element BG21 along the first axis AX1 and the second axis AX2.
[0222] In this embodiment, as Figure 11As shown, when viewed along the first axis 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 planar or arc surfaces, but are not limited thereto.
[0223] 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 guide element BG22 along the first axis AX1, the second axis AX2 and the spindle MX.
[0224] In this embodiment, as Figure 11 As shown, when viewed along the first axis AX1, the third limiting surface FP3 is not parallel to the fourth limiting surface FP4, and when viewed along the first axis AX1, the fourth limiting surface FP4 is not parallel to the fifth limiting surface FP5.
[0225] In this embodiment, as Figure 11 and Figure 12 As shown, when viewed along the first axis 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.
[0226] Please refer to the following: Figure 2 , Figures 11 to 13 . Figure 13 For an optical element driving mechanism 100 according to an embodiment of the present disclosure along Figure 1 A cross-sectional view of the midline segment CC. In this embodiment, the first movable part 108 has a first accommodating space AS1, a portion of the second movable part 109 is located within the first accommodating space AS1, and a portion of the protrusion 112C is located within the first accommodating space AS1.
[0227] Furthermore, in this embodiment, the fifth reinforcing structure YK5 may be made of a magnetically conductive material, and the fifth reinforcing structure YK5 may also have a bent structure YK53 located between the second contact portion YK51 and the third contact portion YK52.
[0228] like Figure 11 and Figure 12 As shown, the fifth reinforcing structure YK5 may also have a reinforcing body YK50, which is connected between the third reinforcing structure YK3 and the fourth reinforcing structure YK4, and the bending structure YK53 is formed by bending the reinforcing body YK50.
[0229] like Figure 12 As shown, the bending structure YK53 bends from the reinforcing body YK50 toward the fourth notch MP23, and when viewed along the first axis AX1, a portion of the bending structure YK53 is exposed by the second movable part 109.
[0230] Further, as shown in Figure 13 , a portion of the bent structure YK53 does not overlap the second contact portion YK51 or the third contact portion YK52 when viewed along the second axial direction AX2.
[0231] Based on such a configuration, the attraction element ACE can be configured to generate a magnetic attraction force ACF with the bent structure YK53, and the magnetic attraction force ACF is parallel to the first axial direction AX1. In addition, as shown in Figure 13 , the optical element driving mechanism 100 further includes a magnetic permeable element YK6 disposed in the protrusion 112C. The attraction element ACE is disposed on the magnetic permeable element YK6, and the magnetic permeable element YK6 is configured to enhance the aforementioned magnetic attraction force ACF. Similarly, the magnetic permeable element YK6 is made of a magnetic permeable material.
[0232] The magnetic attraction force ACF is configured to drive the fifth reinforcing structure YK5 to bring the second movable portion 109 to abut against the base 112, so that the fifth reinforcing structure YK5 and the second plate body MP2 jointly hold the second guide element BG21 and the second guide element BG22.
[0233] In this embodiment, as shown in Figure 13 , a portion of the second guide element BG21 is located in the fourth notch MP23 when viewed along the second axial direction AX2, and the second notch MP21 and the fourth notch MP23 have a first length LH1 when viewed along the second axial direction AX2.
[0234] The third notch MP22 has a second length LH2 when viewed along the second axial direction AX2, and the first length LH1 is greater than the second length LH2. Based on such a configuration, it can be avoided that the second guide element BG21 and the second guide element BG22 cannot be accurately held between the fifth reinforcing structure YK5 and the second plate body MP2 due to tolerance problems.
[0235] In addition, it is worth noting that, as shown in Figure 13 , the first movable portion 108 and the optical element OE can jointly have a center of gravity GTY, and the center of gravity GTY and the first rotation axis RX1 are both on the same side (the upper left side in Figure 13 ) of the reflection surface OES when viewed along the second axial direction AX2.
[0236] Since the center of gravity GTY is closer to the first rotation axis RX1, the moment generated by the center of gravity GTY relative to the first rotation axis RX1 is smaller, so that the first movable portion 108 can be more stable when rotating around the first rotation axis RX1.
[0237] Please continue to refer to Figure 2 , Figure 10 , Figure 11 andFigure 14 . Figure 14 is a perspective view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure. As shown in Figure 10 , the base 112 has a first setting slot GC1 and a second setting slot GC2 configured to accommodate the second coil CL2 and the third coil CL3, respectively.
[0238] Further, as shown in Figure 11 and Figure 14 , the optical element driving mechanism 100 further includes two conductive members 121 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.
[0239] Next, as shown in Figure 2 , the circuit assembly 114 can 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 shown in Figure 14 , in this embodiment, the circuit assembly 114 can further have two through holes 1145 and two electrical contacts 1146, and the two electrical contacts 1146 are partially disposed in the two through holes 1145. Among them, the two through holes 1145 pass through the first circuit portion 1141.
[0240] Correspondingly, the optical element driving mechanism 100 can further include a first reinforcing plate body STP1 fixedly connected to the second circuit portion 1142. The first reinforcing plate body STP1 can be made of a metal material and is configured to reinforce the structural strength of the second circuit portion 1142.
[0241] Similarly, as shown in Figure 2 and Figure 13 , the optical element driving mechanism 100 can further include a second reinforcing plate body STP2 disposed at the bottom of the base 112, and the first circuit portion 1141 is disposed on the second reinforcing plate body STP2.
[0242] It is worth noting that the two through holes 1145 also pass through the second reinforcing plate body STP2. Therefore, as shown in Figure 14 , when viewed along the main axis MX, the two electrical contacts 1146 are exposed by the two through holes 1145.
[0243] Further, as shown in Figure 11 and Figure 14As shown, the second conductive member 121 is electrically connectable to the second coil CL2 and fixedly connected to the second electrical contact 1146. In particular, the second conductive member 121 is fixedly connected to the second electrical contact 1146 by soldering. Based on the configuration of the through hole 1145, the operator can conveniently and quickly solder the conductive member 121 to the electrical contact 1146 so as to electrically connect the second coil CL2 to the circuit assembly 114.
[0244] Next, please refer to Figure 15 . Figure 15 is a top view of a partial structure of the optical element driving mechanism 100 according to an embodiment of the present disclosure. In order to ensure the stability of the first movable part 108 and the second movable part 109 when moving, and to avoid the first movable part 108 or the second movable part 109 from hitting the base 112 when the optical element driving mechanism 100 is impacted, the optical element driving mechanism 100 can further include two adhesive elements GEL1 disposed between the second movable part 109 and the base 112.
[0245] In this embodiment, the adhesive element GEL1 can have an elastic material, and the adhesive element GEL1 is, for example, a gel, but is not limited thereto. It is worth noting that the adhesive element GEL1 is not disposed between the first movable part 108 and the second movable part 109.
[0246] In addition, as shown in Figure 15 , the two adhesive elements GEL1 of this embodiment are symmetrically arranged, for example, symmetrically about the first axial direction AX1 (central axis), and the optical element OE is located between the two adhesive elements GEL1. Based on such a configuration, the stability of the first movable part 108 and the second movable part 109 when moving can be increased.
[0247] In addition, as shown in Figure 15 , when viewed along the main axis MX, the first connecting end 1061 is located between the corresponding first guide element BG12 and the second connecting end 1062. When the first movable part 108 moves relative to the second movable part 109, the elastic restoring force of the first elastic element 106 is applied to the first movable part 108 through the first connecting end 1061. Since the first connecting end 1061 is closer to the first rotation axis RX1, the torque generated by the aforementioned elastic restoring force relative to the first rotation axis RX1 is smaller, so that the first movable part 108 can be more stable when rotating about the first rotation axis RX1.
[0248] The present disclosure provides an optical element driving mechanism 100, which can be a periscopic lens mechanism, comprising a fixed assembly FA, a movable assembly MA, and a driving assembly DA. The movable assembly MA comprises 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 by a first elastic element 106, and the second movable part 109 is movably connected to a base 112 of the fixed assembly FA by a second elastic element 110.
[0249] The optical element driving mechanism 100 can further comprise a first guide element BG11 and a first guide element BG12, which are arranged between the first movable part 108 and the second movable part 109. The optical element driving mechanism 100 can further comprise a force applying element BFE arranged between the first movable part 108 and the second movable part 109. The force applying element BFE can have a first side plate 111, an elastic body 116, and a second side plate 113, the elastic body 116 is arranged between the first side plate 111 and the second side plate 113. The elastic body 116 can be made of an elastic material, and the first side plate 111 and the second side plate 113 are made of a metal material.
[0250] The elastic body 116 can have a pre-pressure PF1 configured to drive the first side plate 111 to push the first guide element BG12, so that the first guide element BG12 abuts against the first movable part 108. The pre-pressure PF1 is the elastic restoring force of the elastic body 116. Based on such configuration, the first guide element BG11 and the first guide element BG12 can be positioned between the first movable part 108 and the second movable part 109, so that the first movable part 108 can stably rotate relative to the second movable part 109 about the first rotation axis RX1.
