Description

TECHNICAL FIELD

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

[0002] With the development of technology, many electronic devices (such as smart phones) nowadays have the function of taking pictures or recording videos. Through the camera module arranged on the electronic device, the user can operate the electronic device to extract various photos.

[0003] The design of the electronic device nowadays is constantly developing towards the trend of miniaturization, so that various elements or structures of the camera module must also be continuously reduced in size to achieve the purpose of miniaturization. Generally speaking, the driving mechanism in the camera module can have a lens carrier configured to carry a lens, and the driving mechanism can have the functions of auto focusing or optical image stabilization. However, although the existing driving mechanism can achieve the above-mentioned functions of taking pictures or recording videos, it still cannot meet all needs.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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

[0163] Further, as shown in FIG. 7, the first reinforcing member 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. Figure 4 Figure 6 In this embodiment, the reinforcing base YK0, the first reinforcing structure YK1, and the second reinforcing structures YK2 can be integrally formed, but are not limited thereto. Further, the first reinforcing member 107 can be a yoke, but is not limited thereto.

[0164] As shown in FIG. 7, each of the second reinforcing structures YK2 can have a first contact portion YK21 configured to abut against a corresponding first guide element. The first guide element BG11 is clamped by the corresponding first contact portion YK21 and the first plate MP1.

[0165] In this embodiment, the first plate MP1 can be made of a metal material, and the first guide element BG11 can be made of a ceramic material, but are not limited thereto. In this embodiment, the hardness of the first guide element BG11 can be greater than the hardness of the first contact portion YK21 or the first plate MP1. Based on such a configuration, the problem of particles generated by friction between the first guide element BG11 and the first plate MP1 can be avoided. Figure 4 Figure 6 Notably, 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.

[0166] As shown in FIG. 7, 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.

[0167]

[0168] As shown in FIG. 7, 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. Figure 6

[0169] ​​​​​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 preventing the first guide element BG11 from damaging the first movable part 108 due to compression.

[0170] Next, as Figure 2 , Figure 6 and Figure 7 As shown, the optical element driving mechanism 100 also includes a force-applying element 111 and a gripping element 113. The first guide element BG12 is located between the first movable part 108 and the gripping element 113, and the gripping element 113 is located between the force-applying element 111 and the first guide element BG12.

[0171] The force-applying element 111 is connected between the gripping element 113 and the second movable part 109, and the force-applying element 111 is made of an elastic material, such as an elastic metal, but not limited thereto. Figure 7 As shown, the force-applying element 111 has a fifth connecting end 1111, two sixth connecting ends 1112, and a third flexible portion 1113.

[0172] The fifth connecting end 1111 is fixedly connected to the gripping element 113, the sixth connecting end 1112 is fixedly connected to the second movable part 109, and the third flexible part 1113 is connected between the fifth connecting end 1111 and the sixth connecting end 1112.

[0173] like Figure 6 As shown, the gripping element 113 has a gripping groove 1131 configured to receive at least a portion of the first guide element BG12. In this embodiment, the first guide element BG12 is fixedly disposed on the first movable portion 108 and is movable relative to the gripping element 113 within the gripping groove 1131.

[0174] like Figure 6 As shown, in this embodiment, the force-applying element 111 has a pre-pressure PF1, configured to drive the fifth connecting end 1111 to drive the gripping element 113 to push the first guide element BG12, so that the first guide element BG12 abuts against the first movable part 108.

[0175] Please refer to the following: Figure 2 , Figure 8 and Figure 9 . Figure 8 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 9 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 8In 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.

[0176] In this embodiment, the drive assembly DA may further include a second drive element MG2, a third drive element MG3, a second coil CL2, and a third coil CL3. The second drive element MG2 and the third drive element MG3 are disposed on the second movable part 109. The second coil CL2 is disposed on the base 112. The second coil CL2 can be electrically connected to the circuit assembly 114 through a circuit structure (e.g., a metal wire, not shown in the figure) embedded in the base 112. The third coil CL3 is disposed on the circuit assembly 114.

[0177] 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.

[0178] like Figure 8 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] like Figure 9As 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 YK31, and the third driving element MG3 is received in the second receiving groove RC2 and abuts against the fifth side YK41.

[0183] Further, the second reinforcing part 115 of the optical element driving mechanism 100 can further include a fifth reinforcing structure YK5, which is partially arranged 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.

[0184] In this embodiment, the fifth reinforcing structure YK5 can be made of metal material, and the third reinforcing structure YK3, the fourth reinforcing structure YK4 and the fifth reinforcing structure YK5 can be integrally formed, but are not limited thereto.

[0185] It is worth mentioning that, as Figure 9 shown, when viewed along the main shaft MX (Z-axis), the second movable part 109 has a U-shaped structure, so based on the arrangement 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.

[0186] Next, as Figure 9 shown, the second driving element MG2 is arranged to induct the second coil CL2 to generate a second electromagnetic driving force MF2, and the third driving element MG3 is arranged to induct 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 shaft RX2.

[0187] 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, so 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 about the second rotation shaft RX2.

[0188] Conversely, when the second electromagnetic driving force MF2 is towards the +Y axis, the third electromagnetic driving force MF3 is towards the -Y axis, so 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 about the second rotation shaft RX2.

[0189] Among them, as Figure 8As shown, the first rotation axis RX1 is perpendicular to the second rotation axis RX2, and 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.

[0190] Please refer to Figure 2 , Figure 8 , Figures 10 to 11 . Figure 10 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 11 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 can further include a second guide element BG21 and a second guide element BG22, which are disposed between the second movable portion 109 and the base 112, and are configured to guide the second movable portion 109 and the first movable portion 108 to rotate around the second rotation axis RX2.

[0191] As shown in Figure 8 and Figure 10 , 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. In addition, the optical element driving mechanism 100 further includes a second plate body MP2, which is fixedly disposed on the base 112.

[0192] As shown in Figure 10 , when viewed along a second axial direction AX2, the second guide element BG21 and the second guide element BG22 are located between the second movable portion 109 and the second plate body MP2.

[0193] As shown in Figure 8 , in the direction of the second axial direction 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.

[0194] As shown in Figure 10 and Figure 11 , the second plate body MP2 has a second notch MP21 and a third notch MP22, which are configured to accommodate a portion of the second guide element BG21 and the second guide element BG22, respectively.

[0195] Correspondingly, the fifth reinforcing structure YK5 has a second contact portion YK51 and a third contact portion YK52, configured to abut against the second guide element BG21 and the second guide element BG22, respectively.

[0196] Specifically, the second guide element BG21 is clamped by the second contact portion YK51 and the second plate body MP2, and the second guide element BG22 is clamped by the third contact portion YK52 and the second plate body MP2.

[0197] As shown in Figure 10 , the base 112 has a back plate 112BP and a protrusion 112C, and the protrusion 112C protrudes from the back plate 112BP toward the second movable portion 109 along the first axial direction AX1. The optical element driving mechanism 100 can further include an attracting element ACE fixedly arranged in the protrusion 112C. The attracting element ACE is made of a magnetic material, for example, a magnet, but is not limited thereto.

[0198] Further, as shown in Figure 10 and Figure 11 , the second plate body MP2 further has a fourth notch MP23 communicating with the second notch MP21. As shown in Figure 10 , when viewed along the first axial direction AX1, the attracting element ACE overlaps the fourth notch MP23. Specifically, when viewed along the first axial direction AX1, the attracting element ACE is exposed by the fourth notch MP23.

[0199] Further, as shown in Figure 10 and Figure 11 , 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 axial direction AX1 and the second axial direction AX2.

[0200] In this embodiment, as shown in Figure 10 , 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 planar or circular arc surfaces, but are not limited thereto.

[0201] 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 axial direction AX1, the second axial direction AX2, and the main shaft MX.

[0202] In this embodiment, as shown in Figure 10As shown, the third limiting face FP3 is not parallel to the fourth limiting face FP4 when viewed along the first axial direction AX1, and the fourth limiting face FP4 is not parallel to the fifth limiting face FP5 when viewed along the first axial direction AX1.

[0203] In this embodiment, as shown in Figure 10 and Figure 11 As shown, the third limiting face FP3, the fourth limiting face FP4, and the fifth limiting face FP5 can form a triangle when viewed along the first axial direction AX1, but are not limited thereto.

[0204] Next, please refer to Figure 2 , Figures 10 to 12 . Figure 12 A cross-sectional view of the optical element driving mechanism 100 along the middle line segment C-C according to an embodiment of the present disclosure. In this embodiment, the first movable portion 108 has a first accommodating space AS1, a portion of the second movable portion 109 is located in the first accommodating space AS1, and a portion of the protrusion 112C is located in the first accommodating space AS1. Figure 1

[0205] Further, in this embodiment, the fifth reinforcing structure YK5 can be made of a magnetically conductive material, and the fifth reinforcing structure YK5 can further have a bent structure YK53 located between the second contact portion YK51 and the third contact portion YK52.

[0206] As shown, the fifth reinforcing structure YK5 can further have a reinforcing body YK50 connected between the third reinforcing structure YK3 and the fourth reinforcing structure YK4, and the bent structure YK53 is bent from the reinforcing body YK50. Figure 10 and Figure 11 As shown, the bent structure YK53 is bent from the reinforcing body YK50 toward the fourth notch MP23, and a portion of the bent structure YK53 is exposed by the second movable portion 109 when viewed along the first axial direction AX1.

[0207] As shown, the bent structure YK53 is bent from the reinforcing body YK50 toward the fourth notch MP23, and a portion of the bent structure YK53 is exposed by the second movable portion 109 when viewed along the first axial direction AX1. Figure 11 Further, as shown, 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.

[0208] Figure 12 Based on such a configuration, the attracting 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.

[0209] Based on such a configuration, the attracting 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.

[0210] ​​The magnetic force ACF is configured to drive the fifth reinforcing structure YK5 to move the second movable part 109 towards the base 112 to abut, 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.

[0211] In this embodiment, as shown in Figure 12 , 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.

[0212] 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 clamped between the fifth reinforcing structure YK5 and the second plate body MP2 due to tolerance problems.

[0213] In addition, it is worth noting that, as shown in Figure 12 , the first movable part 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 on the same side (the upper left side in Figure 12 ) of the reflection surface OES when viewed along the second axial direction AX2.

[0214] 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 part 108 can be more stable when rotating around the first rotation axis RX1.

[0215] Further, as shown in Figure 2 , the circuit assembly 114 can have a first circuit part 1141 and a second circuit part 1142, and the first circuit part 1141 is connected to the second circuit part 1142. Correspondingly, the optical element driving mechanism 100 can further include a first reinforcing plate body STP1 fixedly connected to the second circuit part 1142. The first reinforcing plate body STP1 can be made of metal material and is configured to reinforce the structural strength of the second circuit part 1142.

[0216] Similarly, as shown in Figure 2 and Figure 12 , the optical element driving mechanism 100 can further include a second reinforcing plate body STP2 arranged at the bottom of the base 112, and the first circuit part 1141 is arranged on the second reinforcing plate body STP2.

[0217] Then please refer to Figure 13 . Figure 13Fig. 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 stability when the first movable part 108 and the second movable part 109 move, 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.

[0218] In this embodiment, the adhesive elements GEL1 can be made of elastic material, such as gel, but are not limited thereto. It is worth noting that the adhesive elements GEL1 are not disposed between the first movable part 108 and the second movable part 109.

[0219] In addition, as shown in Fig. 1, 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 an arrangement, the stability when the first movable part 108 and the second movable part 109 move can be increased. Figure 13

[0220] The present disclosure provides an optical element driving mechanism 100, which can be a periscopic lens mechanism, including a fixed assembly FA, a movable assembly MA, and a driving assembly DA. The movable assembly MA includes 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 the base 112 of the fixed assembly FA by a second elastic element 110.

[0221] The optical element driving mechanism 100 can further include a first guide element BG11 and a first guide element BG12 disposed between the first movable part 108 and the second movable part 109. The optical element driving mechanism 100 can further include a force applying element 111 and a holding element 113, the holding element 113 is arranged to hold the first guide element BG12, a portion of the force applying element 111 is fixed to the second movable part 109, and another portion of the force applying element 111 is fixed to the holding element 113.

[0222] The force applying element 111 is made of elastic material and is arranged to provide a pre-pressure PF1 to drive the holding element 113 to push the first guide element BG12 so that the first guide element BG12 abuts against the first movable part 108. Based on such an arrangement, 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 to enable the first movable part 108 to stably rotate relative to the second movable part 109 about the first rotation axis RX1.​
