Description

Technical Field

[0001] The present invention relates to an optical element driving mechanism, and more particularly to an optical element driving mechanism having a piezoelectric element.

Background Art

[0002] With the development of technology, many electronic devices (such as smartphones) today have functions for taking photos and videos. By using a camera module mounted on an electronic device, a user can operate the electronic device to take various photos or videos.

[0003] Today's design of electronic devices is continuously trending towards miniaturization. As a result, various components or the structure of the imaging module must also be continuously reduced to achieve the goal of miniaturization. Generally, the driving mechanism in an imaging module can have a lens carrier member configured to carry a lens, and the driving mechanism can have functions such as auto focusing or optical image stabilization. However, although the current driving mechanism can realize the aforementioned photo-taking or video-taking functions, it still cannot meet all requirements.

[0004] Therefore, how to design an imaging module that can perform rapid positioning and multiple functions has become an issue to be discussed and solved today.

[0025] As shown in Figures 1 and 2, Figure 1 is a schematic perspective view of an optical element driving mechanism 10 according to one embodiment of the present invention, and Figure 2 is an exploded view of the optical element driving mechanism 10 according to one embodiment of the present invention. The optical element driving mechanism 10 can be an optical imaging system configured to support and drive an imaging module 150. The optical element driving mechanism 10 can be attached to various electronic devices or portable electronic devices (e.g., smart TVs or notebook computers) to enable users to perform image capture functions.

[0026] In this embodiment, the optical element driving mechanism 10 may have the first optical module 100 and the second optical module 200 described above. The second optical module 200 is mounted on the first optical module 100, and the second optical module 200 is configured to support the imaging module 150.

[0027] As shown in Figures 1 and 2, the first optical module 100 includes a fixed assembly FA, ​​a first movable part 108, a first drive assembly DA1, and a first rotary assembly 120. The fixed assembly FA includes a first base 112, and the first movable part 108 is configured to be movably connected to the first base 112 along the spindle MX.

[0028] The first movable part 108 is configured to be connected to the second optical module 200, and the first movable part 108 is movable relative to the fixed assembly FA. Furthermore, the first drive assembly DA1 is configured to move the first movable part 108 relative to the fixed assembly FA.

[0029] Specifically, the first movable part 108 is movably connected to the first base 112 via the first rotation assembly 120, and the first drive assembly DA1 moves the first movable part 108 via the first rotation assembly 120. Specifically, the first movable part 108 can rotate around the first rotation axis RX1. In this embodiment, the first rotation axis RX1 overlaps with the spindle MX, but is not limited to this.

[0030] On the other hand, the second optical module 200 may include a second movable part 208, a second base 212, and a second drive assembly DA2. The second base 212 is fixedly mounted on the first movable part 108, and the second movable part 208 can move relative to the second base 212. In this embodiment, the first movable part 108 and the second base 212 may be integrally molded.

[0031] The second optical module 200 may further include a second rotating assembly 220 and a fixed shaft 230, and the second movable part 208 is movably connected to the second base 212 via the second rotating assembly 220 and the fixed shaft 230.

[0032] The fixed shaft 230 passes through the second base 212 and the second rotational assembly 220, and the second drive assembly DA2 moves the second movable part 208 via the second rotational assembly 220. Specifically, the second movable part 208 can rotate around the second rotational axis RX2, which is defined by the fixed shaft 230. The second rotational axis RX2 may, for example, be perpendicular to the first rotational axis RX1, but is not limited thereto.

[0033] Next, as shown in Figures 2 to 4, Figure 3 is a top view of a partial structure of the first optical module 100 according to one embodiment of the present invention, and Figure 4 is a rear view of a partial structure of the first optical module 100 according to one embodiment of the present invention. The first optical module 100 further includes a first positioning base 109 configured to be connected to a first base 112, and a first drive assembly DA1 configured to be fixed on the first positioning base 109.

[0034] As shown in Figures 2 and 3, the first base 112 can be defined to have a first axial direction AX1 and a second axial direction AX2, where the second axial direction AX2 is perpendicular to the first axial direction AX1.

[0035] The first optical module 100 may further include a first connection assembly LA1 configured to connect the first drive assembly DA1 and the first positioning base 109 to the first base 112. As shown in Figure 2, the first connection assembly LA1 includes a first connecting member 106, which is, for example, a screw, but is not limited thereto.

[0036] As shown in Figure 2, the first connecting member 106 is configured to extend along the first axial direction AX1 and pass through the first positioning base 109 and the first drive assembly DA1 to connect the first positioning base 109 and the first drive assembly DA1. For example, after passing through the first drive assembly DA1, the first connecting member 106 is fixed into the first positioning hole 1091 of the first positioning base 109.

[0037] Next, the first positioning base 109 and the first drive assembly DA1 are attached to the mounting portion 112D of the first base 112 along the first axial direction AX1. Specifically, as shown in Figures 2 to 4, the mounting portion 112D of the first base 112 may have a first housing space AS1 configured to accommodate at least a portion of the first drive assembly DA1 and the first positioning base 109.

[0038] In this embodiment, as shown in Figures 2 and 4, the first positioning base 109 has a first lateral projection 1092 and a second lateral projection 1093. Correspondingly, the first base 112 can have a first guide groove 1121 and a second guide groove 1122 configured to guide the first lateral projection 1092 and the second lateral projection 1093, respectively.

[0039] When viewed along the first axial direction AX1 (Y-axis), as shown in Figure 4, the first lateral projection 1092 has a first corresponding surface 1094, a second corresponding surface 1095, and a first terminal portion 1096. The first terminal portion 1096 is connected between the first corresponding surface 1094 and the second corresponding surface 1095.

[0040] As shown in Figure 4, the first lateral projection 1092 has a substantially triangular structure, and the angle between the first corresponding surface 1094 and the second corresponding surface 1095 is 60 degrees or less, but is not limited to this.

[0041] Furthermore, the first guide groove 1121 has a third corresponding surface 1123, a fourth corresponding surface 1124, and a second terminal portion 1125. The second terminal portion 1125 is connected between the third corresponding surface 1123 and the fourth corresponding surface 1124. The third corresponding surface 1123 is configured to correspond to the first corresponding surface 1094, the fourth corresponding surface 1124 is configured to correspond to the second corresponding surface 1095, and the second terminal portion 1125 does not contact the first terminal portion 1096.

[0042] Specifically, there is a gap between the second terminal portion 1125 and the first terminal portion 1096. Similarly, there is a gap between the second side projection 1093 and the second guide groove 1122. Furthermore, there is a gap between the third corresponding surface 1123 and the first corresponding surface 1094, and a gap between the fourth corresponding surface 1124 and the second corresponding surface 1095. Based on this structural configuration, it is guaranteed that the first positioning base 109 can be smoothly attached to the mounting portion 112D.

[0043] Furthermore, in this embodiment, the second lateral projection 1093 is symmetrical to the first lateral projection 1092, and the second guide groove 1122 is symmetrical to the first guide groove 1121. Therefore, since the second lateral projection 1093 and the second guide groove 1122 have the same structure as the first lateral projection 1092 and the first guide groove 1121, a detailed explanation thereof is omitted here.

[0044] Furthermore, in this embodiment, the first connection assembly LA1 further includes a second connecting member 110 configured to connect the first positioning base 109 and the first base 112. As shown in Figures 2 and 4, the second connecting member 110 has an elastic material, such as an elastic spring sheet, but is not limited thereto.

[0045] As shown in Figure 4, the second connecting member 110 has a first connecting end 1101, a second connecting end 1102, two first flexible portions 1103, and a third connecting end 1104. The first connecting end 1101 and the third connecting end 1104 are fixedly connected to the mounting portion 112D of the first base 112, and the second connecting end 1102 is fixedly connected to the first positioning base 109.

[0046] One of the two first flexible portions 1103 is connected between the first connection end 1101 and the second connection end 1102, and the other is connected between the third connection end 1104 and the second connection end 1102.

[0047] Specifically, the first base 112 has a first fixing projection BP1, a second fixing projection BP2, a third fixing projection BP3, and a fourth fixing projection BP4. The first connecting end 1101 has a first mounting hole HP1 and a second mounting hole HP2, which are mounted on the first fixing projection BP1 and the second fixing projection BP2, respectively.

[0048] When viewed along the first axial direction AX1, the dimensions of the first mounting hole HP1 are slightly larger than the dimensions of the first fixing projection BP1, for example, 1.05 times. When viewed along the first axial direction AX1, the dimensions of the second mounting hole HP2 are larger than the dimensions of the second fixing projection BP2, for example, 1.5 times. When viewed along the first axial direction AX1, the second mounting hole HP2 has an elongated hole shape structure that extends along the second axial direction AX2.

[0049] Similarly, the third connecting end 1104 has a third mounting hole HP3 and a fourth mounting hole HP4, which are fitted into the third fixing projection BP3 and the fourth fixing projection BP4, respectively. When viewed along the first axial direction AX1, the dimensions of the third mounting hole HP3 are approximately equal to the dimensions of the third fixing projection BP3 (within tolerance limits). When viewed along the first axial direction AX1, the dimensions of the fourth mounting hole HP4 are slightly larger than the dimensions of the fourth fixing projection BP4, for example, by 1.05 times.

[0050] Furthermore, as shown in Figures 3 and 4, the first positioning base 109 may have a central fixing projection 109P that penetrates the second connecting end 1102. Since the second connecting member 110 is elastic, the first flexible portion 1103 and the second connecting end 1102 generate an elastic restoring force in the first positioning base 109, biasing the first positioning base 109 and the first drive assembly DA1 so that the first drive assembly DA1 makes reliable contact with the first rotation assembly 120, and thus the first rotation assembly 120 can be driven accurately. In this embodiment, the elastic restoring force (preload) is, for example, 100 grams or less, but is not limited thereto.

[0051] In this embodiment, as shown in Figures 2 and 3, the first drive assembly DA1 includes a first transmission assembly 104, a first contact member 105, and a first power source 114. The first power source 114 is configured to generate a first driving force, and the first transmission assembly 104 is configured to transmit the first driving force.

[0052] In this embodiment, the first transmission assembly 104 has an elastic structure that can deflect and output a first driving force. Specifically, the first power source 114 can be a first piezoelectric element configured to generate deformation and bias the first transmission assembly 104 so that the first transmission assembly 104 deflects and outputs a first driving force.

[0053] The first contact member 105 has a semi-cylindrical structure and is fixedly mounted on the first transmission assembly 104 and configured to transmit the first driving force. The first rotation assembly 120 is mounted on the first base 112 and a portion of the first rotation assembly 120 is configured to move relative to the first contact member 105.

[0054] Specifically, when the first transmission assembly 104 flexes, the first contact member 105 can be moved along an elliptical trajectory (as seen along the main axis MX, as shown in Figure 3), thereby repeatedly contacting and moving a portion of the first rotation assembly 120. The operation of the first transmission assembly 104 and the first contact member 105 can be found in Chinese Patent Application No. 202420942976.X, so it will not be repeated here.

[0055] It should be noted that, as shown in Figures 2 and 3, the first accommodation space AS1 may have a first avoidance space AP1 corresponding to the first transmission assembly 104. The first avoidance space AP1 is, for example, an opening, and a portion of the first transmission assembly 104 is located within the first avoidance space AP1. Based on the configuration of the first avoidance space AP1, the problem of the first transmission assembly 104 colliding with and being damaged by the first base 112 when it flexes can be avoided.

[0056] Furthermore, as shown in Figures 2 and 3, the first rotating assembly 120 is fitted onto a positioning projection 112P of the first base 112, and the first rotating assembly 120 has a first stator 121, a first rotor 122, and a plurality of first rolling balls 123. The first stator 121 is located between the positioning projection 112P and the first rotor 122, and these first rolling balls 123 are located between the first stator 121 and the first rotor 122, allowing the first rotor 122 to rotate relative to the first stator 121.

[0057] The first movable part 108 is fixedly connected to the first rotor 122, and the first contact member 105 causes the first rotor 122 to rotate around the first rotation axis RX1 relative to the first stator 121 based on the aforementioned first driving force, and the first movable part 108 causes the second optical module 200 to rotate around the first rotation axis RX1. The first rotation axis RX1 can be defined by a positioning projection 112P.

[0058] Next, as shown in Figures 2 and 5 to 7, Figure 5 is a perspective view of a partial structure of the optical element driving mechanism 10 according to one embodiment of the present invention. Figure 6 is a perspective view of a partial structure of the optical element driving mechanism 10 from another viewpoint according to one embodiment of the present invention. Figure 7 is a cross-sectional view of the optical element driving mechanism 10 along line AA in Figure 1 according to one embodiment of the present invention.

[0059] As shown in Figures 2, 5, and 6, the first optical module 100 may further include a first circuit assembly 116, an integrated circuit assembly 130, and an external connection circuit assembly 132. The first circuit assembly 116 and the integrated circuit assembly 130 are fixedly mounted on the first base 112, and the first circuit assembly 116 can be electrically connected to an external circuit via the integrated circuit assembly 130 and the external connection circuit assembly 132.

[0060] As shown in Figures 2 and 5, the first circuit assembly 116 has a first segment 1161, a second segment 1162, a third segment 1163, and a fourth segment 1164. The positioning projection 112P has a top surface 112T and a side wall 112L. The first segment 1161 and the second segment 1162 are fixed to the top surface 112T and the side wall 112L, respectively.

[0061] The third segment 1163 is connected between the second segment 1162 and the fourth segment 1164, and the fourth segment 1164 is bent from the third segment 1163 and electrically connected to the integrated circuit assembly 130. Specifically, as shown in Figure 6, the first connector CN1 is installed on the integrated circuit assembly 130 and configured to connect to the fourth segment 1164.

[0062] The first base 112 further has a communication opening 112H, and the second segment 1162 is bent from the third segment 1163, passes through the communication opening 112H, and connects to the first segment 1161. The communication opening 112H passes through the first base 112 along the main axis MX.

[0063] As shown in Figure 5, the first segment 1161 has a first positioning hole 1165, and the positioning projection 112P further has a first mounting projection FP1 that penetrates the first positioning hole 1165. When viewed along the main spindle MX (Z axis), the first mounting projection FP1 and the first positioning hole 1165 have a semicircular structure.

[0064] Based on the semicircular structural design, the first segment 1161 can be precisely positioned. In addition, adhesive (not shown) may be provided between the first segment 1161 and the top surface 112T, and adhesive may also be provided between the second segment 1162 and the side wall 112L, thereby securely fixing the first segment 1161 and the second segment 1162 onto the top surface 112T and the side wall 112L, respectively.

[0065] In addition, as shown in Figures 5 and 7, the third segment 1163 has a second positioning hole 1166 and a third positioning hole 1167. Correspondingly, the first base 112 further has a second mounting projection FP2 and a third mounting projection FP3 extending along the main spindle MX and passing through the second positioning hole 1166 and the third positioning hole 1167, respectively.

[0066] When viewed along the spindle MX, as shown in Figure 5, the dimensions of the second positioning hole 1166 are larger than the dimensions of the second mounting projection FP2, for example, 1.5 times. When viewed along the spindle MX, the second positioning hole 1166 has an elongated hole shape structure that extends along the first axial direction AX1.

[0067] When viewed along the spindle MX, the dimensions of the third positioning hole 1167 are slightly larger than the dimensions of the third mounting projection FP3, for example, by 1.05 times. When viewed along the spindle MX, the third positioning hole 1167 has a circular structure.

[0068] Based on the design of the first positioning hole 1165, the second positioning hole 1166, and the third positioning hole 1167 described above, the first circuit assembly 116 can be more easily mounted onto the first base 112.

[0069] It should also be noted that two first electrical contacts EC1 are formed on the third segment 1163 and are configured to be electrically connected to the first power source 114. When viewed along the spindle MX, these first electrical contacts EC1 are exposed from the first base 112, facilitating welding to the lead wires WR1 and WR2 of the first power source 114.

[0070] As shown in Figure 4, the first positioning base 109 can form two notches 1098, and the two lead wires WR1 and WR2 of the first power source 114 (as shown in Figure 5) can be led through the two notches 1098 to the first electrical contact EC1.

[0071] Furthermore, as shown in Figures 2, 3, and 7, the first optical module 100 further includes a first magnetic member MG1, which is fixedly positioned at the bottom of the first movable part 108.

[0072] As shown in Figure 3, when viewed along the spindle MX, the positioning projection 112P forms a first corner notch 112C. When viewed along the spindle MX, the first magnetic member MG1 forms a second corner notch MG11 corresponding to the first corner notch 112C.

[0073] The first corner notch 112C communicates with the communication opening 112H. Based on the configuration of the first corner notch 112C, the second segment 1162 can extend from the communication opening 112H and can be easily attached to the side wall 112L.

[0074] Furthermore, based on the configuration of the second corner notch MG11, when the first magnetic member MG1 is attached to the first movable part 108, the alignment direction of the magnetic poles of the first magnetic member MG1 is accurate, and it can be guaranteed that there will be no problems with incorrect installation.

[0075] Next, as shown in Figures 3 and 7, the first optical module 100 further includes a first sensing member SE1 mounted on the first segment 1161. Specifically, the first sensing member SE1 is housed in a housing recess 112R of a positioning projection 112P and is located at the bottom of the first segment 1161.

[0076] As shown in Figure 7, when viewed along the second axial direction AX2 (X-axis), the first sensing member SE1 and the first magnetic member MG1 are located on both sides opposite the first segment 1161. Based on the above configuration, the objective of miniaturizing the first optical module 100 can be achieved.

[0077] The first sensing member SE1 is configured to sense changes in the magnetic field of the first magnetic member MG1 and to obtain the position of the first movable part 108 relative to the first base 112. In this embodiment, the first sensing member SE1 is, for example, a Hall sensor or a tunnel magnetoresistance sensor (TMR sensor), but is not limited thereto. It should be noted that, as shown in Figure 3, the first sensing member SE1 has a rectangular structure, its long side is parallel to the second axial direction AX2, and the direction of the arrangement of the magnetic poles of the first magnetic member MG1 is also parallel to the second axial direction AX2.

[0078] Furthermore, as shown in Figure 7, the first base 112 further has a first housing surface 1120 installed within the first housing space AS1 and is configured to support a portion of the first positioning base 109, and the first avoidance space AP1 is adjacent to the first housing surface 1120. In this embodiment, when viewed along the main spindle MX, the area of ​​the first housing surface 1120 can be less than or equal to the area of ​​the first positioning base 109.

[0079] As shown in Figure 8, Figure 8 is a schematic top view of one embodiment of the present invention in which the first movable part 108 is driven to a different position. In this embodiment, the mounting part 112D of the first base 112 further includes a first stopper part 141 and a second stopper part 142.

[0080] The first stopper portion 141 and the second stopper portion 142 may, for example, have a chamfered structure, and the first stopper portion 141 and the second stopper portion 142 may, but are not limited to, be made of a plastic material.

[0081] As shown in Figure 8, when the first movable part 108 is driven by the first drive assembly DA1 and rotates along the first rotation direction RD1 (clockwise direction), the first movable part 108 is configured to come into contact with the first stopper part 141. When the first movable part 108 comes into contact with the first stopper part 141, the position of the first movable part 108 can be referred to as the first limit position P1.

[0082] Conversely, when the first movable part 108 is driven by the first drive assembly DA1 and rotates along the second rotation direction RD2, the first movable part 108 is configured to contact the second stopper part 142. When the first movable part 108 contacts the second stopper part 142, the position of the first movable part 108 can be referred to as the second limit position P2. The second rotation direction RD2 is opposite to the first rotation direction RD1.

[0083] Next, as shown in Figures 2, 7 to 9, Figure 9 is an enlarged schematic diagram of an optical element driving mechanism 10 according to one embodiment of the present invention. Similar to the first optical module 100, the second optical module 200 may further include the second driving assembly DA2 and the second positioning base 209 described above.

[0084] A second positioning base 209 is fixedly mounted on a second base 212, and the second optical module 200 further includes a second connection assembly LA2 configured to connect a second drive assembly DA2 and a second positioning base 209 to the second base 212 and a first movable part 108.

[0085] Specifically, as shown in Figure 2, the second connection assembly LA2 includes a third connecting member 206 configured to connect the second positioning base 209 and the second drive assembly DA2. For example, the third connecting member 206 may be, but is not limited to, a screw that passes through the second drive assembly DA2 and is then secured to the second positioning hole 2091 of the second positioning base 209.

[0086] It should be noted that the extending direction of the third connecting member 206 is parallel to the extending direction of the first connecting member 106. Therefore, this configuration can improve the convenience of mounting the first optical module 100 and the second optical module 200.

[0087] Next, the second positioning base 209 and the second drive assembly DA2 are mounted to the second base 212 along the first axial direction AX1. As shown in Figures 7 and 9, the second base 212 may further have a second accommodating space AS2 configured to accommodate at least a portion of the second positioning base 209 and the second drive assembly DA2. The second accommodating space AS2 is, for example, a recess, but is not limited thereto.

[0088] Similar to the first optical module 100, in this embodiment, as shown in Figure 9, the second positioning base 209 has a third lateral projection 2092 and a fourth lateral projection 2093. Correspondingly, the second base 212 can be formed to have a third guide groove 2121 and a fourth guide groove 2122 configured to guide the third lateral projection 2092 and the fourth lateral projection 2093, respectively.

[0089] Furthermore, the fourth lateral projection 2093 is symmetrical with respect to the third lateral projection 2092, and the fourth guide groove 2122 is symmetrical with respect to the third guide groove 2121. The structural configurations of the third lateral projection 2092 and the fourth lateral projection 2093 are the same as or similar to those of the first lateral projection 1092 and the second lateral projection 1093, and the structural configurations of the third guide groove 2121 and the fourth guide groove 2122 are the same as or similar to those of the first guide groove 1121 and the second guide groove 1122; therefore, their specific structures will not be repeated here.

[0090] The second connection assembly LA2 may further include a fourth connecting member 210 configured to connect the second positioning base 209 and the second base 212. The fourth connecting member 210 is made of an elastic material, such as an elastic spring sheet, but is not limited thereto.

[0091] The fourth connecting member 210 has a fourth connecting end 2101, a fifth connecting end 2102, two second flexible portions 2103, and a sixth connecting end 2104. The fourth connecting end 2101 and the sixth connecting end 2104 are fixedly connected to the second base 212, and the fifth connecting end 2102 is fixedly connected to the second positioning base 209.

[0092] One of the two second flexible portions 2103 is connected between the fourth connection end 2101 and the fifth connection end 2102, and the other is connected between the sixth connection end 2104 and the fifth connection end 2102.

[0093] Specifically, the second base 212 has a fifth fixing projection BP5, a sixth fixing projection BP6, a seventh fixing projection BP7, and an eighth fixing projection BP8. The fourth connecting end 2101 has a fifth mounting hole HP5 and a sixth mounting hole HP6, and is fitted onto the fifth fixing projection BP5 and the sixth fixing projection BP6, respectively.

[0094] When viewed along the first axial direction AX1, the dimensions of the fifth mounting hole HP5 are slightly larger than the dimensions of the fifth fixing projection BP5, for example, 1.05 times. When viewed along the first axial direction AX1, the dimensions of the sixth mounting hole HP6 are larger than the dimensions of the sixth fixing projection BP6, for example, 1.5 times. When viewed along the first axial direction AX1, the sixth mounting hole HP6 has an elongated hole shape structure that extends along the second axial direction AX2.

[0095] Similarly, the sixth connecting end 2104 has a seventh mounting hole HP7 and an eighth mounting hole HP8, which are fitted into the seventh fixing projection BP7 and the eighth fixing projection BP8, respectively. When viewed along the first axial direction AX1, the dimensions of the seventh mounting hole HP7 are substantially equal to (within tolerance limits) the dimensions of the seventh fixing projection BP7. When viewed along the first axial direction AX1, the dimensions of the eighth mounting hole HP8 are slightly larger than the dimensions of the eighth fixing projection BP8, for example, by 1.05 times.

[0096] Similarly, as shown in Figure 9, the second positioning base 209 may have a central fixed projection 209P that penetrates the fifth connecting end 2102. Since the fourth connecting member 210 is elastic, the second flexible portion 2103 and the fifth connecting end 2102 can generate an elastic restoring force in the second positioning base 209, biasing the second positioning base 209 and the second drive assembly DA2 so that the second drive assembly DA2 makes secure contact with the second rotation assembly 220, and thus the second rotation assembly 220 can be driven accurately.

[0097] Furthermore, as shown in Figures 2, 6, 9, and 10, Figure 10 is a top view of an optical element driving mechanism 10 according to one embodiment of the present invention. As shown, the second optical module 200 may further include a second circuit assembly 216 configured to be electrically connected to the second driving assembly DA2 and the integrated circuit assembly 130.

[0098] In this embodiment, as shown in Figure 2, the second circuit assembly 216 has a fifth segment 2161, a sixth segment 2162, a seventh segment 2163, and an eighth segment 2164. The fifth segment 2161 is fixedly connected to the second base 212. The sixth segment 2162 is connected between the fifth segment 2161 and the seventh segment 2163, and the seventh segment 2163 extends along the main spindle MX.

[0099] The eighth segment 2164 is bent from the seventh segment 2163 and connected to the integrated circuit assembly 130. Specifically, as shown in Figure 6, a second connector CN2 is installed on the integrated circuit assembly 130, configured to connect the eighth segment 2164.

[0100] It should be noted that the sixth segment 2162 is bent from the fifth segment 2161 and connected to the seventh segment 2163. As shown in Figure 10, when viewed along the main axis MX, the sixth segment 2162 can have a V-shaped structure.

[0101] The second circuit assembly 216 is, for example, a flexible circuit board, and based on the above configuration, when the first movable part 108 causes the second optical module 200 to rotate around the first rotation axis RX1, the sixth segment 2162 can extend or contract in conjunction with the first movable part 108, thereby avoiding the problem of the second circuit assembly 216 being damaged without affecting the movement of the first movable part 108.

[0102] Furthermore, as shown in Figure 6, a third connector CN3 is installed on the integrated circuit assembly 130 and configured to connect to the external connection circuit assembly 132. That is, the signals from the first circuit assembly 116 and the second circuit assembly 216 are integrated on the integrated circuit assembly 130 and then output to the aforementioned external circuit via the external connection circuit assembly 132.

[0103] As shown in Figures 2 and 7, in this embodiment the second rotating assembly 220 may have a second stator 221, a second rotor 222, and a plurality of second balls 223. The second stator 221 is located between the stationary shaft 230 and the second rotor 222, and these second balls 223 are located between the second stator 221 and the second rotor 222, allowing the second rotor 222 to rotate relative to the second stator 221.

[0104] Similar to the first drive assembly DA1, the second drive assembly DA2 may include a second transmission assembly 204, a second contact member 205, and a second power source 214. The second power source 214 is configured to generate a second driving force, and the second transmission assembly 204 is configured to transmit the second driving force, and the second transmission assembly 204 may have an elastic structure that can flex to output the second driving force.

[0105] Specifically, the second power source 214 can be a second piezoelectric element configured to deform and bias the second transmission assembly 204, causing the second transmission assembly 204 to bend and output a second driving force.

[0106] Similarly, the second contact member 205 is fixedly mounted on the second transmission assembly 204 and configured to transmit the second driving force. When the second transmission assembly 204 flexes, the second contact member 205 can be made to move along an elliptical trajectory (viewed along the second axial direction AX2 as shown in Figure 7), repeatedly contacting and rotating the second rotor 222. The specific mode of operation is the same as that of the first drive assembly DA1.

[0107] Furthermore, as shown in Figure 7, the second movable part 208 is fixedly connected to the second rotor 222, and the second driving force is transmitted to the second rotor 222 via the second contact member 205, causing the second rotor 222 and the second movable part 208 to rotate around the second rotation axis RX2 relative to the second stator 221, and the second movable part 208 causes the imaging module 150 to rotate around the second rotation axis RX2.

[0108] Next, as shown in Figure 11, Figure 11 is a side view of an optical element driving mechanism 10 according to one embodiment of the present invention. In this embodiment, as shown in Figure 11, the second base 212 may have a third stopper portion 2123 and a fourth stopper portion 2124, and when the second movable portion 208 is made to rotate around the second rotation axis RX2, the third stopper portion 2123 and the fourth stopper portion 2124 are configured to stop the second movable portion 208 and limit the range of rotation angle of the second movable portion 208.

[0109] The third stopper portion 2123 can be, for example, an inclined surface, and the fourth stopper portion 2124 can be, for example, an arc-shaped guide angle, but is not limited to these. Based on such a configuration, the rotation angles of the second movable portion 208 will differ. For example, in Figure 11, the maximum clockwise rotation angle of the second movable portion 208 (with the horizontal line as 0 degrees) can be greater than the maximum counterclockwise rotation angle. Such a configuration can ensure that the second movable portion 208 does not collide with the first movable portion 108.

[0110] Furthermore, as shown in Figures 2, 10, and 11, the second optical module 200 further includes a second sensing member SE2 and a second magnetic member MG2, the second magnetic member MG2 being mounted on a second movable part 208 and the second sensing member SE2 being mounted on a fifth segment 2161.

[0111] As shown in Figure 10, when viewed along the main axis MX, the second sensing member SE2 and the second magnetic member MG2 are located on both sides opposite the fifth segment 2161. Also, as shown in Figure 11, when viewed along the second axial direction AX2, the second magnetic member MG2 has a third corner notch MG21. The configuration and advantages of the third corner notch MG21 are the same as those of the second corner notch MG11, so a detailed explanation is omitted here.

[0112] As described above, the present invention provides an optical element driving mechanism 10 including a first optical module 100, a second optical module 200, a first drive assembly DA1, and a second drive assembly DA2. The second movable part 208 of the second optical module 200 is configured to support the imaging module 150, and the second optical module 200 is fixedly mounted on the first movable part 108 of the first optical module 100. The first drive assembly DA1 is configured to rotate the first movable part 108 and the second optical module 200 around a first rotation axis RX1, and the second drive assembly DA2 is configured to rotate the second movable part 208 and the imaging module 150 around a second rotation axis RX2 relative to the first movable part 108 and the first base 112.

[0113] Furthermore, the first optical module 100 further includes a first connecting member 106 and a second connecting member 110. The first drive assembly DA1 is fixedly mounted on the first positioning base 109 via the first connecting member 106, and the first positioning base 109 is connected to the first base 112 via the second connecting member 110. The first connecting member 106 may be a screw, and the second connecting member 110 may be an elastic spring seat. The second connecting member 110 is configured to provide an elastic restoring force (or preload) to the first positioning base 109, biasing the first positioning base 109 and the first drive assembly DA1 so that the first contact member 105 can accurately drive the first rotation assembly 120.

[0114] Furthermore, the first positioning base 109 has a first lateral projection 1092 and a second lateral projection 1093, and the first base 112 can form a first guide groove 1121 and a second guide groove 1122 corresponding to these, which are configured to guide the first lateral projection 1092 and the second lateral projection 1093, respectively. The second lateral projection 1093 is symmetrical to the first lateral projection 1092, and the second guide groove 1122 is symmetrical to the first guide groove 1121. The first lateral projection 1092 and the first guide groove 1121 have a triangular structure, and there is a gap between the first lateral projection 1092 and the first guide groove 1121. Based on this configuration, the convenience of attaching the first positioning base 109 to the first base 112 can be improved.
