[0244] Please refer to Figure 5 and Figure 6 , Figure 5 This is a top view of an optical element driving mechanism 1-100 according to an embodiment of the present disclosure, and Figure 6This is a top view of a portion of the structure of an optical element driving mechanism 1-100 according to an embodiment of the present disclosure.

Specifically, in the third direction 1-D3, the maximum size of the first magnetic element 1-ME1 is larger than the maximum size of the second magnetic element 1-ME2.

[0250] In the first direction 1-D1, the maximum size of the first magnetic element 1-ME1 is different from the maximum size of the second magnetic element 1-ME2.

[0252] Based on the above structural configuration, the electromagnetic driving force and the attraction force between the magnetic element and the corresponding magnetic conductive element can be effectively adjusted, so that the first movable assembly 1-MA1 and the second movable assembly 1-MA2 with different moving ranges can be kept in good balance.

[0253] In this embodiment, the first fixed element 1-1061 and the second fixed element 1-1062 can constitute a fixed member 1-106. The second fixed element 1-1062 and the first fixed element 1-1061 have an integral structure, that is, they are not connected by means of glue, welding, etc.

[0254] In the first direction 1-D1, a first end 1-1063 of the fixed member 1-106 with a long strip structure does not contact the fixed assembly 1-FA. In the first direction 1-D1, a second end 1-1064 of the fixed member 1-106 does not contact the fixed assembly 1-FA, and the first end 1-1063 and the second end 1-1064 are arranged along the first direction 1-D1.

[0255] Please refer to Figure 5 and Figure 7 , Figure 7 is a cross-sectional view of the optical element driving mechanism 1-100 along the YZ plane according to an embodiment of the present disclosure.

The second fixed surface 1-1072 is located at the first end 1-1063 and is parallel to the first surface 1-MS1. The third fixed surface 1-1073 is located at the first end 1-1063 and faces in the opposite direction of the second fixed surface 1-1072. The fourth fixed surface 1-1074 is located at the first end 1-1063 and is perpendicular to the first fixed surface 1-1071 and the second fixed surface 1-1072.

The seventh fixing surface 1-1077 faces the opposite direction to the sixth fixing surface 1-1076. The sixth fixing surface 1-1076 is located at the second fixing element 1-1062, and the seventh fixing surface 1-1077 is located at the second fixing element 1-1062.

[0259] like Figure 5 As shown, in the first direction 1-D1, the shortest distance between the first fixing surface 1-1071 and the fixing assembly 1-FA is less than the shortest distance between the fifth fixing surface 1-1075 and the fixing assembly 1-FA. Specifically, the shortest distance between the first fixing surface 1-1071 and the base 1-104 in the first direction 1-D1 is not zero. That is, the first fixing surface 1-1071 does not contact the base 1-104.

[0260] In a direction perpendicular to the second fixing surface 1-1072, for example, in the third direction 1-D3, the shortest distance between the second fixing surface 1-1072 and the fixing assembly 1-FA is greater than the shortest distance between the third fixing surface 1-1073 and the fixing assembly 1-FA. For example, the third fixing surface 1-1073 contacts the base 1-104, but the second fixing surface 1-1072 does not contact the base 1-104.

[0261] Furthermore, the shortest distance between the first fixing surface 1-1071 and the fixing component 1-FA is greater than the shortest distance between the fourth fixing surface 1-1074 and the fixing component 1-FA. Specifically, the fourth fixing surface 1-1074 contacts the base 1-104, but the first fixing surface 1-1071 does not contact the base 1-104.

[0262] When viewed along the first direction 1-D1, the fifth fixing surface 1-1075 overlaps at least a portion of the seventh fixing surface 1-1077. In the first direction 1-D1, the shortest distance between the sixth fixing surface 1-1076 and the fixing assembly 1-FA is less than the shortest distance between the seventh fixing surface 1-1077 and the fixing assembly 1-FA.

[0263] Based on the above structural design, the fixing member 1-106 can be accurately positioned on the base 1-104, and the overall structural strength can be increased.

[0264] Please refer to Figure 2 , Figure 5 and Figure 8 , Figure 8 is a magnified view of the optical element driving mechanism 1-100 according to an embodiment of the present disclosure. In this embodiment, the base 1-104 of the fixing assembly 1-FA further includes a positioning assembly 1-PA configured to position the fixing member 1-106. The positioning assembly 1-PA has a protruding structure extending along a direction (Z-axis) perpendicular to the first direction 1-D1 and the third direction 1-D3.

[0265] Further, the optical element driving mechanism 1-100 includes an adjusting magnetic element 1-AE located between the first loading portion 1-108 and the second loading portion 1-112, configured to adjust the magnetic force between the first magnetic element 1-ME1 and the second magnetic element 1-ME2, so as to avoid the first magnetic element 1-ME2 and the second magnetic element 1-ME2 from interfering with each other to affect the movement of the first movable assembly 1-MA1 and the second movable assembly 1-MA2.

[0266] The adjusting magnetic element 1-AE is fixedly arranged on the positioning assembly 1-PA, and the adjusting magnetic element 1-AE can have a U-shaped structure. The adjusting magnetic element 1-AE can be made of metal, but is not limited thereto.

[0267] Please continue to refer to Figures 2 to 8 . The optical element driving mechanism 1-100 further includes a first guide assembly 1-GA1 configured to guide the first movable assembly 1-MA1 to move relative to the fixing assembly 1-FA along the first direction 1-D1. The first guide assembly 1-GA1 includes a guide rod 1-120 having an elongated structure extending along the first direction 1-D1. The guide rod 1-120 passes through the first loading portion 1-108 of the first movable assembly 1-MA1. When viewed along a fourth direction 1-D4 (Z-axis) perpendicular to the first direction 1-D1 and the third direction 1-D3, the guide rod 1-120 overlaps at least a portion of the first movable assembly 1-MA1.

[0268] Similarly, the guide rod 1-120 of the first guide assembly 1-GA1 is configured to guide the second movable assembly 1-MA2 to move relative to the fixing assembly 1-FA along the first direction 1-D1. The guide rod 1-120 passes through the second loading portion 1-112 of the second movable assembly 1-MA2. When viewed along the fourth direction 1-D4, the guide rod 1-120 overlaps at least a portion of the second movable assembly 1-MA2.

[0269] In this embodiment, the shortest distance between the first driving assembly 1-DA1 and the guide rod 1-120 is the same as the shortest distance between the second driving assembly 1-DA2 and the guide rod 1-120. For example, as shown in Figure 5 the shortest distance between the first coil 1-CL1 and the guide rod 1-120 is the same as the shortest distance between the second coil 1-CL2 and the guide rod 1-120 (in the third direction 1-D3).

[0270] In addition, as shown in Figure 6 the shortest distance between the first magnetic element 1-ME1 and the guide rod 1-120 is the same as the shortest distance between the second magnetic element 1-ME2 and the guide rod 1-120 (in the third direction 1-D3). Similarly, the shortest distance between the first magnetic enhancement element 1-SM1 and the guide rod 1-120 is the same as the shortest distance between the second magnetic enhancement element 1-SM2 and the guide rod 1-120 (in the third direction 1-D3).

[0271] As shown in Figure 6 the shortest distance between the first magnetic element 1-ME1 and the guide rod 1-120 is the same as the shortest distance between the second magnetic element 1-ME2 and the guide rod 1-120 (in the third direction 1-D3). Similarly, the shortest distance between the first magnetic enhancement element 1-SM1 and the guide rod 1-120 is the same as the shortest distance between the second magnetic enhancement element 1-SM2 and the guide rod 1-120 (in the third direction 1-D3).

[0272] Based on the above-described structural configuration, the purpose of miniaturization can be achieved, and the overall balance can also be achieved.

At least a portion of first driving assembly 1-DA1 is fixedly disposed on base 1-104. For example, fixing member 1-106 is fixedly disposed on base 1-104.

[0288] It is worth noting that the magnetic permeability of bottom plate 1-102 is lower than that of first magnetically permeable element 1-CM1 or second magnetically permeable element 1-CM2, so as to avoid the problem of magnetic field interference. In addition, base 1-104 and positioning assembly 1-PA have an integrated structure, so as to increase the overall structural strength.

[0289] As shown in Figure 10 , base 1-104 is formed with a notch 1-104C configured to accommodate control element 1-162. Base 1-104 does not overlap first sensing element 1-SE1 when viewed along fourth direction 1-D4. Specifically, first sensing element 1-SE1 is not shielded by base 1-104. Furthermore, base 1-104 overlaps at least a portion of control element 1-162 when viewed along fourth direction 1-D4, and circuit assembly 1-160 is disposed between base 1-104 and bottom plate 1-102.

The third side edge 1-100S3 is parallel to the optical axis 1-O, and the third side edge 1-100S3 and the fourth side edge 1-100S4 are parallel to each other.

Therefore, based on the above design, the optical system 1-10 is disposed at the fourth side 1-100S4 which is free of any driving components or sensing elements, so that the space in the electronic device can be effectively utilized, and the overall size can be reduced.

[0333] In the first direction 2-D1, a first end 2-1063 of the fixed member 2-106 with an elongated structure does not contact the fixed assembly 2-FA. In the first direction 2-D1, a second end 2-1064 of the fixed member 2-106 does not contact the fixed assembly 2-FA, and the first end 2-1063 and the second end 2-1064 are arranged along the first direction 2-D1.

[0334] Please refer to Figure 16 and Figure 18 , Figure 18 is a cross-sectional view of the optical element driving mechanism 2-100 along the YZ plane according to an embodiment of the present disclosure.

The sixth fixed surface 2-1076 is located at the second fixed element 2-1062, and the seventh fixed surface 2-1077 is located at the second fixed element 2-1062.

[0338] As shown in FIG. 10, in the first direction 2-D1, the shortest distance between the first fixed surface 2-1071 and the fixed assembly 2-FA is smaller than the shortest distance between the fifth fixed surface 2-1075 and the fixed assembly 2-FA. Specifically, the shortest distance between the first fixed surface 2-1071 and the base 2-104 in the first direction 2-D1 is not zero. That is, the first fixed surface 2-1071 does not contact the base 2-104. Figure 16

[0339] In a direction perpendicular to the second fixed surface 2-1072, such as the third direction 2-D3, the shortest distance between the second fixed surface 2-1072 and the fixed assembly 2-FA is greater than the shortest distance between the third fixed surface 2-1073 and the fixed assembly 2-FA. For example, the third fixed surface 2-1073 contacts the base 2-104, but the second fixed surface 2-1072 does not contact the base 2-104.

[0340] Further, the shortest distance between the first fixed surface 2-1071 and the fixed assembly 2-FA is greater than the shortest distance between the fourth fixed surface 2-1074 and the fixed assembly 2-FA. Specifically, the fourth fixed surface 2-1074 contacts the base 2-104, but the first fixed surface 2-1071 does not contact the base 2-104.

[0341] When viewed along the first direction 2-D1, the fifth fixed surface 2-1075 overlaps at least a portion of the seventh fixed surface 2-1077. In the first direction 2-D1, the shortest distance between the sixth fixed surface 2-1076 and the fixed assembly 2-FA is smaller than the shortest distance between the seventh fixed surface 2-1077 and the fixed assembly 2-FA.

[0343] Please refer to Figure 13 , Figure 16 and Figure 19 , Figure 19 FIG. 2B is an enlarged view of the optical element driving mechanism 2-100 according to an embodiment of the present disclosure. In this embodiment, the base 2-104 of the fixing assembly 2-FA further includes a positioning assembly 2-PA configured to position the fixing member 2-106. The positioning assembly 2-PA has a protruding structure extending along a direction (Z-axis) perpendicular to the first direction 2-D1 and the third direction 2-D3.

[0344] Further, the optical element driving mechanism 2-100 includes a magnetic adjusting element 2-AE located between the first loading portion 2-108 and the second loading portion 2-112 and configured to adjust the magnetic force between the first magnetic element 2-ME1 and the second magnetic element 2-ME2 to avoid magnetic force interference between the first magnetic element 2-ME2 and the second magnetic element 2-ME2 affecting the movement of the first movable assembly 2-MA1 and the second movable assembly 2-MA2.

[0345] The magnetic adjusting element 2-AE is fixedly arranged on the positioning assembly 2-PA, and the magnetic adjusting element 2-AE can have a U-shaped structure. The magnetic adjusting element 2-AE can be made of metal, for example, but is not limited thereto.

[0346] Please continue to refer to Figures 13 to 19 . The optical element driving mechanism 2-100 further includes a guide rod 2-120 configured to guide the movement of the first movable assembly 2-MA1 relative to the fixing assembly 2-FA along the first direction 2-D1. The guide rod 2-120 has an elongated structure extending along the first direction 2-D1. The guide rod 2-120 passes through the first loading portion 2-108 of the first movable assembly 2-MA1. When viewed along a fourth direction 2-D4 (Z-axis) perpendicular to the first direction 2-D1 and the third direction 2-D3, the guide rod 2-120 overlaps at least a portion of the first movable assembly 2-MA1.

[0347] Similarly, the guide rod 2-120 is configured to guide the movement of the second movable assembly 2-MA2 relative to the fixing assembly 2-FA along the first direction 2-D1. The guide rod 2-120 passes through the second loading portion 2-112 of the second movable assembly 2-MA2. When viewed along the fourth direction 2-D4, the guide rod 2-120 overlaps at least a portion of the second movable assembly 2-MA2.

[0348] In this embodiment, the shortest distance between the first driving assembly 2-DA1 and the guide rod 2-120 is the same as the shortest distance between the second driving assembly 2-DA2 and the guide rod 2-120. For example, as shown in FIG. 1A, the shortest distance between the first coil 2-CL1 and the guide rod 2-120 is the same as the shortest distance between the second coil 2-CL2 and the guide rod 2-120 (in the third direction 2-D3).

[0349] In addition, as shown in FIG. 1A, the shortest distance between the first magnetic element 2-ME1 and the guide rod 2-120 is the same as the shortest distance between the second magnetic element 2-ME2 and the guide rod 2-120 (in the third direction 2-D3). Similarly, the shortest distance between the first magnetic-shielding element 2-SM1 and the guide rod 2-120 is the same as the shortest distance between the second magnetic-shielding element 2-SM2 and the guide rod 2-120 (in the third direction 2-D3). Figure 17

[0350] As shown in FIG. 1A, the shortest distance between the first magnetic-shielding element 2-CM1 and the guide rod 2-120 is different from the shortest distance between the second magnetic-shielding element 2-CM2 and the guide rod 2-120. Specifically, the shortest distance between the first magnetic-shielding element 2-CM1 and the guide rod 2-120 is smaller than the shortest distance between the second magnetic-shielding element 2-CM2 and the guide rod 2-120 (in the third direction 2-D3). Figure 17

[0351] In this embodiment, the first loading portion 2-108 is configured to load the first magnetic element 2-ME1, and the second loading portion 2-112 is configured to load the second magnetic element 2-ME2. In addition, as shown in FIG. 1A, the fixing assembly 2-FA further has a first blocking portion 2-104P disposed between the first loading portion 2-108 and the second loading portion 2-112. The first blocking portion 2-104P is integrally formed with the positioning assembly 2-PA. Figure 16

[0352] The first blocking portion 2-104P is configured to block the first movable assembly 2-MA1 in the first extreme range 2-ER1, and the first blocking portion 2-104P is configured to block the second movable assembly 2-MA2 in the second extreme range 2-ER2. For example, when the first movable assembly 2-MA1 moves to the leftmost side of the first extreme range 2-ER1, it will abut against the first blocking portion 2-104P, and when the second movable assembly 2-MA2 moves to the rightmost side of the second extreme range 2-ER2, it will abut against the first blocking portion 2-104P.

[0353] As shown in FIG. 1A, Figure 16 , Figure 17 and Figure 19 ​​​​As shown, the guide rod 2-120 passes through the first loading portion 2-108, the first blocking portion 2-104P, and the second loading portion 2-112, and the guide rod 2-120 is fixedly arranged on the fixed assembly 2-FA. Specifically, the first blocking portion 2-104P can be formed with a groove 2-104T and a recess 2-104G, which are in communication with each other. The guide rod 2-120 is arranged in the groove 2-104T, and the magnetic adjusting element 2-AE surrounds a portion of the recess 2-104G. The optical element driving mechanism 2-100 can further include an adhesive element 2-GE (for example, glue) flowing from the recess 2-104G and into the groove 2-104T, so that the magnetic adjusting element 2-AE and the guide rod 2-120 can be stably fixed to the positioning assembly 2-PA and the first blocking portion 2-104P.

[0354] Based on the above structure configuration, the purpose of miniaturization can be achieved, and the overall balance can also be achieved.

[0355] In addition, as shown in Figure 13 , Figure 17 and Figure 18 , the optical element driving mechanism 2-100 further includes a circuit assembly 2-160 and a control element 2-162. The circuit assembly 2-160 is, for example, a flexible circuit board, and the control element 2-162 is, for example, a control integrated circuit (IC), arranged on the circuit assembly 2-160.

[0356] The control element 2-162 is configured to control the first driving assembly 2-DA1 to drive the first movable assembly 2-MA1 to move relative to the fixed assembly 2-FA, and the control element 2-162 is configured to control the second driving assembly 2-DA2 to drive the second movable assembly 2-MA2 to move relative to the fixed assembly 2-FA.

[0357] Next, please refer to Figure 13 , Figure 17 and Figure 20 , Figure 20 is a perspective view of part of the structure of the optical element driving mechanism 2-100 according to an embodiment of the present disclosure. In this embodiment, the optical element driving mechanism 2-100 can further include a first guide assembly 2-GA1 directly contacting the guide rod 2-120, and the first guide assembly 2-GA1 includes at least two first guide elements 2-121 arranged in the first loading portion 2-108 of the first movable assembly 2-MA1. The first guide elements 2-121 are configured to abut the guide rod 2-120.

[0358] When viewed along the first direction 2-D1 or the fourth direction 2-D4 (Z-axis), the first magnetic element 2-ME1 is located between the first guide elements 2-121 and the first magnetic-conductive element 2-CM1. Notably, as shown in Figure 14 When viewed along the first direction 2-D1 (Y-axis), the first guide elements 2-121 and the center line of the guide rod 2-120 form an included angle 2-AG greater than 0 degrees and less than 180 degrees.

[0359] In this embodiment, the first guide elements 2-121 have a spherical structure, and at least two first grooves 2-108C are formed in the first loading portion 2-108 of the first movable assembly 2-MA1, and the first guide elements 2-121 are respectively fixed in the first grooves 2-108C. Therefore, when the first loading portion 2-108 of the first movable assembly 2-MA1 moves along the guide rod 2-120, the first guide elements 2-121 will not rotate relative to the first grooves 2-108C.

[0360] As shown in Figure 17 and as shown in Figure 20 In this embodiment, a plurality of first guide assemblies 2-GA1 (for example, two first guide assemblies 2-GA1) can be arranged in the first loading portion 2-108 along the first direction 2-D1. Based on arranging two pairs of first guide elements 2-121 on opposite sides of the first loading portion 2-108, the stability of the first loading portion 2-108 during movement can be ensured.

[0361] In addition, as shown in Figure 14 and as shown in Figure 20 The first loading portion 2-108 only contacts the guide rod 2-120 through the first guide assemblies 2-GA1, and the first loading portion 2-108 does not directly touch the guide rod 2-120. Specifically, as shown in Figure 14 A magnetic attraction force is generated between the first magnetic element 2-ME1 and the first magnetic-conductive element 2-CM1 to attract the first loading portion 2-108 along the third direction 2-D3 towards the first fixed element 2-1061, so that the guide rod 2-120 can be reliably abutted against the first guide elements 2-121. Based on the above structural configuration, the stability of the first loading portion 2-108 during movement along the first direction 2-D1 can be further ensured.

[0362] Similarly, the optical element driving mechanism 2-100 also includes a second guide assembly 2-GA2 directly contacting the guide rod 2-120, and the second guide assembly 2-GA2 includes at least two second guide elements 2-122 arranged in the second loading portion 2-112 of the second movable assembly 2-MA2. The second guide elements 2-122 are configured to abut the guide rod 2-120.

[0363] When viewed along the first direction 2-D1 or the fourth direction 2-D4, the second magnetic element 2-ME2 is located between the second guide elements 2-122 and the second magnetic conductive element 2-CM2. Notably, as shown, when viewed along the first direction 2-D1, the second guide elements 2-122 and the center line of the guide rod 2-120 form an included angle greater than 0 degrees and less than 180 degrees. Figure 15

[0364] In this embodiment, the second guide elements 2-122 have a spherical structure, and at least two second grooves 2-112C are formed in the second loading portion 2-112 of the second movable assembly 2-MA2, and the second guide elements 2-122 are respectively fixed in the second grooves 2-112C. Therefore, when the second loading portion 2-112 of the second movable assembly 2-MA2 moves along the guide rod 2-120, the second guide elements 2-122 will not rotate relative to the second grooves 2-112C.

[0365] As shown in Figure 17 and as shown in Figure 20 In this embodiment, a plurality of second guide assemblies 2-GA2 can be arranged in the second loading portion 2-112 along the first direction 2-D1. Based on the two pairs of second guide elements 2-122 arranged on opposite sides of the second loading portion 2-112, the stability of the second loading portion 2-112 during movement can be ensured.

[0366] In addition, as shown in Figure 15 and as shown in Figure 20 The second loading portion 2-112 only contacts the guide rod 2-120 through the second guide assemblies 2-GA2, and the second loading portion 2-112 does not directly touch the guide rod 2-120. Similarly, based on the above structural configuration, the stability of the second loading portion 2-112 during movement can be further ensured.

[0367] Next, please refer to Figure 21 and Figure 22 , Figure 21 is a perspective view of a partial structure of an optical element driving mechanism 2-100 according to another embodiment of the present disclosure, and Figure 22 is a cross-sectional view of the optical element driving mechanism 2-100 along the XZ plane according to another embodiment of the present disclosure. In this embodiment, the configuration of the first loading portion 2-108, the first guide assembly 2-GA1, and the guide rod 2-120 is the same as that of the previous embodiment, and thus will not be described here.

[0368] ​In this embodiment, the optical element driving mechanism 2-100 may further include at least one second guide assembly 2-GA2 disposed within the second loading portion 2-112, and the guide rod 2-120 passes through the second guide assembly 2-GA2. For example, the second guide assembly 2-GA2 may be a through hole formed in the second loading portion 2-112.

[0369] When viewed along the first direction 2-D1, the second guiding component 2-GA2 may include a first abutting slope 2-1121, a second abutting slope 2-1122, and an intermediate surface 2-1123. The intermediate surface 2-1123 is not parallel to the first abutting slope 2-1121 and the second abutting slope 2-1122, and is connected to both the first abutting slope 2-1121 and the second abutting slope 2-1122. In this embodiment, the intermediate surface 2-1123 may be an arc surface, but is not limited thereto.

[0370] like Figure 22 As shown, when viewed along the first direction 2-D1, the second magnetic element 2-ME2 of the second drive assembly 2-DA2 is located between the first abutting ramp 2-1121 and the second magnetically conductive element 2-CM2. The second magnetic element 2-ME2 and the second magnetically conductive element 2-CM2 can be collectively referred to as a second pressure-applying assembly, configured to generate a magnetic attraction (or repulsion) to draw the second loading portion 2-112 toward the second fixing element 2-1062, ensuring that the guide rod 2-120 reliably contacts the first abutting ramp 2-1121 and the second abutting ramp 2-1122. Specifically, the first abutting ramp 2-1121 and the second abutting ramp 2-1122 are configured to abut the guide rod 2-120.

[0371] In this embodiment, when viewed along the first direction 2-D1, the included angle between the first abutting inclined surface 2-1121 and the second abutting inclined surface 2-1122 can be greater than 45 degrees and less than 180 degrees.

[0372] Furthermore, such as Figure 21 As shown, the second loading section 2-112 is provided with a plurality of second guide components 2-GA2 (through holes) arranged along the first direction 2-D1, and the second loading section 2-112 contacts the guide rod 2-120 only through these second guide components 2-GA2. That is to say, the guide rod 2-120 does not contact the intermediate surface 2-1123.

[0373] It is worth noting that the guide rod 2-120 may be equipped with dry lubricating oil or wet lubricating oil to ensure that the first loading part 2-108 and the second loading part 2-112 can move smoothly along the guide rod 2-120.

[0374] Also, it is to be noted that the embodiments of the first guide assembly 2-GA1 and the second guide assembly 2-GA2 are not limited to the above-described examples. For example, the embodiments of the first guide assembly 2-GA1 and the second guide assembly 2-GA2 can be exchanged or identical. For example, both the first guide assembly 2-GA1 and the second guide assembly 2-GA2 can be the through hole having the first abutting inclined surface 2-1121, the second abutting inclined surface 2-1122, and the intermediate surface 2-1123.

[0375] Please refer to Figure 17 , Figure 23 and Figure 24 , Figure 23 is a perspective view of a partial structure of an optical element driving mechanism 2-100 according to an embodiment of the present disclosure, and Figure 24 is a sectional view of the optical element driving mechanism 2-100 along the YZ plane according to an embodiment of the present disclosure. The optical element driving mechanism 2-100 further includes a first guide member 2-131 and a second guide member 2-132 fixedly provided on the frame 2-105 of the fixed assembly 2-FA.

[0376] The first guide member 2-131 and the second guide member 2-132 correspond to the first sliding portion 2-109 and the second sliding portion 2-113, respectively, and have a plate-like structure. As shown in Figure 23 and Figure 24 , the first sliding portion 2-109 is provided with a first slider 2-133 and a first magnet 2-MG1.

[0377] When viewed along the first direction 2-D1, the first slider 2-133 is located between the first magnet 2-MG1 and the first guide member 2-131. The first magnet 2-MG1 is configured to generate a first magnetic attraction force with the first guide member 2-131, so that the first sliding portion 2-109 drives the first slider 2-133 to abut against the first guide member 2-131.

[0378] Similarly, the second sliding portion 2-113 is provided with a second slider 2-134 and a second magnet 2-MG2. When viewed along the second direction 2-D2, the second slider 2-134 is located between the second magnet 2-MG2 and the second guide member 2-132.

[0379] The second magnet 2-MG2 is configured to generate a second magnetic attractive force with the second guide member 2-132 to cause the second sliding portion 2-113 to drive the second slider 2-134 to abut against the second guide member 2-132. In this embodiment, the first slider 2-133 and the second slider 2-134 have a spherical structure and can roll with respect to the first sliding portion 2-109 and the second sliding portion 2-113, respectively.

[0380] Based on the above configuration, it can be ensured that the first sliding portion 2-109 and the second sliding portion 2-113 can be stably moved along the first guide member 2-131 and the second guide member 2-132, respectively.

[0381] In this embodiment, the first guide member 2-131 and the second guide member 2-132 have different lengths in the first direction 2-D1 (Y-axis). For example, the length of the first guide member 2-131 is smaller than the length of the second guide member 2-132.

[0382] Further, in a fourth direction 2-D4 perpendicular to the first direction 2-D1 and the third direction 2-D3, the size of the first guide member 2-131 is different from the size of the second guide member 2-132. Specifically, in the fourth direction 2-D4 (Z-axis), the size (e.g. thickness) of the first guide member 2-131 is smaller than the size (e.g. thickness) of the second guide member 2-132.

[0383] As shown in Figure 17 When viewed along the fourth direction 2-D4 (Z-axis), the center of the first guide element 2-121 of the right first guide assembly 2-GA1, the center of the first guide element 2-121 of the left first guide assembly 2-GA1, and the center of the first slider 2-133 form a triangular structure which can enclose the center of the first optical element 2-OE1.

[0384] Similarly, when viewed along the fourth direction 2-D4, the center of the second guide element 2-122 of the right second guide assembly 2-GA2, the center of the second guide element 2-122 of the left second guide assembly 2-GA2, and the center of the second slider 2-134 form a triangular structure which can enclose the center of the second optical element 2-OE2.

[0385] Please refer back to Figure 16 and Figure 17 As shown in the figure, the optical element driving mechanism 2-100 further comprises two first buffer elements 2-141 arranged on opposite sides of the first loading portion 2-108 along the first direction 2-D1. Further, the optical element driving mechanism 2-100 can further comprise two second buffer elements 2-142 arranged on opposite sides of the second loading portion 2-112 along the first direction 2-D1.

[0386] These first buffer elements 2-141 are configured to abut against a front side 2-1042 of the first blocking portion 2-104P or the fixed assembly 2-FA when the first loading portion 2-108 moves in the first extreme range 2-ER1, and these second buffer elements 2-142 are configured to abut against a rear side 2-1044 of the first blocking portion 2-104P or the fixed assembly 2-FA when the second loading portion 2-112 moves in the second extreme range 2-ER2.

[0387] In some embodiments, the first buffer elements 2-141 and the second buffer elements 2-142 can be made of sponge, rubber, or silicone.

[0388] Similarly, the fixed assembly 2-FA also has a second blocking portion 2-105P disposed between the first sliding portion 2-109 and the second sliding portion 2-113, configured to block the first sliding portion 2-109 and the second sliding portion 2-113. In addition, the two sides of the first sliding portion 2-109 and the two sides of the second sliding portion 2-113 can also be provided with buffer elements to ensure that the first sliding portion 2-109 and the second sliding portion 2-113 will not be damaged due to impact.

[0389] The maximum length 2-112L of the second loading portion 2-112 in the first direction 2-D1 is greater than the maximum length 2-113L of the second sliding portion 2-113 in the first direction 2-D1. In the third direction 2-D3, the maximum dimension 2-108W of the first loading portion 2-108 is greater than the maximum dimension 2-109W of the first sliding portion 2-109.

[0390] Furthermore, the length 2-PL1 of the first blocking portion 2-104P in the first direction 2-D1 is less than the length 2-PL2 of the second blocking portion in the first direction 2-D1. Based on the above structural design, the structural strength of the second blocking portion 2-105P can be increased to avoid damage due to impact.

[0391] Please refer back to Figure 16 In this embodiment, the optical element driving mechanism 2-100 can further include a third optical element 2-OE3 fixedly connected to the base 2-104. The third optical element 2-OE3 can be a lens configured to diffuse or concentrate a light ray 2-L. The base 2-104 has a recessed structure 2-1041 corresponding to the third optical element 2-OE3.

[0392] Similarly, the third optical element 2-OE3 is fixedly connected to the frame 2-105. Specifically, the frame 2-105 has a recessed structure 2-1051 corresponding to the third optical element 2-OE3.

[0393] Light ray 2-L sequentially passes through third optical element 2-OE3, first optical element 2-OE1, and second optical element 2-OE2 to be incident on a photosensitive assembly 2-190, which can include a photosensitive element (not shown) configured to receive light ray 2-L to generate a digital image signal. In this embodiment, photosensitive assembly 2-190 can be fixed to base 2-104, for example.

[0394] Next, refer to Figure 16 and Figure 25 and Figure 25 is a perspective view of optical element driving mechanism 2-100 from another angle according to an embodiment of the present disclosure. In this view, third optical element 2-OE3, first movable assembly 2-MA1, second movable assembly 2-MA2, and photosensitive assembly 2-190 are sequentially arranged along a main axis 2-AX.

[0395] In this embodiment, first movable assembly 2-MA1 has a first receiving slot 2-RS1 corresponding to first optical element 2-OE1, and second movable assembly 2-MA2 has a second receiving slot 2-RS2 corresponding to second optical element 2-OE2.

[0396] First optical element 2-OE1 is fixed to first receiving slot 2-RS1 by a first adhesive element 2-AD1. Specifically, first adhesive element 2-AD1 is disposed within first receiving slot 2-RS1, and first receiving slot 2-RS1 is recessed from a first receiving surface 2-108S of first movable assembly 2-MA1.

[0397] First receiving slot 2-RS1 further includes a first filling portion 2-RS11 and a first narrow portion 2-RS12, and in first direction 2-D1, the largest dimension of first filling portion 2-RS11 is greater than that of first narrow portion 2-RS12. First narrow portion 2-RS12 is closer to first optical element 2-OE1 than first filling portion 2-RS11.

[0398] Similarly, second optical element 2-OE2 is fixed to second receiving slot 2-RS2 by a second adhesive element 2-AD2. Specifically, second adhesive element 2-AD2 is disposed within second receiving slot 2-RS2, and second receiving slot 2-RS2 is recessed from a second receiving surface 2-112S of second movable assembly 2-MA2.

[0399] Second receiving slot 2-RS2 further includes a second filling portion 2-RS21 and a second narrow portion 2-RS22, and in second direction 2-D2, the largest dimension of second filling portion 2-RS21 is greater than that of second narrow portion 2-RS22.

[0400] In addition, in the first direction 2-D1, the maximum dimension of the first narrow portion 2-RS12 is smaller than the maximum dimension of the second narrow portion 2-RS22, and in the first direction 2-D1, the maximum dimension of the first filling portion 2-RS11 is smaller than the maximum dimension of the second filling portion 2-RS21.

[0401] In addition, in the first direction 2-D1, the maximum dimension of the first narrow portion 2-RS12 is smaller than the maximum dimension of the second narrow portion 2-RS22, and in the first direction 2-D1, the maximum dimension of the first filling portion 2-RS11 is smaller than the maximum dimension of the second filling portion 2-RS21.

[0402] In summary, the present disclosure provides an optical element driving mechanism 2-100, comprising a first driving assembly 2-DA1 and a second driving assembly 2-DA2, configured to drive a first movable assembly 2-MA1 and a second movable assembly 2-MA2, respectively, to move along a first dimension.

In addition, the first driving assembly 2-DA1 comprises a first magnetically conductive element 2-CM1 and a first magnetic element 2-ME1, the first magnetically conductive element 2-CM1 is fixed to the fixed member 2-106, and the first magnetic element 2-ME1 is fixed to the first movable assembly 2-MA1. Based on the magnetic attraction force between the first magnetically conductive element 2-CM1 and the first magnetic element 2-ME1, the stability of the first movable assembly 2-MA1 moving along the guide rod 2-120 can be further increased.
