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 technology]

[0002] With the advancement of technology, many electronic devices (such as smartphones) are now equipped with photo and video capture functions. Through the imaging module installed on the electronic device, users can operate the electronic device and take various photos.

[0003] The design of modern electronic devices is constantly moving toward miniaturization. To achieve this goal, various components or structures of an imaging module must also be reduced in size. Generally, a driving mechanism in an imaging module has a lens carrier that mounts a lens, and the driving mechanism has functions such as autofocusing or optical image stabilization. However, while existing driving mechanisms have the aforementioned functions of photographing and video recording, they do not meet all requirements.

[0027] In this embodiment, the optical element driving mechanism 100 includes a fixed assembly FA, ​​a movable part 108, and a drive assembly DA.

[0028] In this embodiment, as shown in FIG. 2 , the fixing assembly FA includes a casing 102 and a base 112. The casing 102 has a hollow structure, and a casing opening 1021 is formed thereon. A base opening 1121 is formed on the base 112. The center of the casing opening 1021 corresponds to the optical axis O of the optical element OE, and the base opening 1121 corresponds to a photosensitive element (not shown) installed below the base 112.

The photosensitive element may be, for example, but is not limited to, an image sensor.

[0029] Furthermore, the casing 102 and the base 112 are arranged along a main axis MX, and the casing 102 is fixedly installed on the base 112. The main axis MX overlaps with or is parallel to the optical axis O. The casing 102 further has a receiving space 1023 for receiving elements such as the movable part 108 and the drive assembly DA.

[0030] Further, please refer to Figures 2 and 4. Figure 4 is a top view of a partial structure of the optical element driving mechanism 100 according to one embodiment of the present invention. As shown in Figure 4, when viewed along the main axis MX, the base 112 of the fixing assembly FA has a polygonal structure, for example, a rectangular structure.

[0031] As shown in Fig. 4, when viewed along the main axis MX, the drive assembly DA is located on a first side SS1 of the polygonal structure (i.e., the bottom side of the rectangular structure). As shown in Figs. 2 and 4, the optical element drive mechanism 100 further includes a circuit assembly 114 electrically connected to the drive assembly DA. When viewed along the main axis MX, the circuit assembly 114 is located on the first side SS1. The circuit assembly 114 may be, for example, but is not limited to, a flexible circuit board.

[0032] 2, the circuit assembly 114 has an L-shaped structure having a first circuit portion 1141 and a second circuit portion 1142. Accordingly, the base 112 has a dividing wall 112W, and the first circuit portion 1141 and the second circuit portion 1142 are disposed on the dividing wall 112W. When viewed along the main axis MX, the dividing wall 112W is also located on the first side SS1.

[0033] 2 and 4, the optical element driving mechanism 100 further includes a sensing assembly SA configured to sense movement of the movable part 108. Similarly, when viewed along the main axis MX, the sensing assembly SA is also located on the first side SS1.

[0034] In this embodiment, the sensing assembly SA includes a sensing element SE and a sensing magnet MG. The sensing magnet MG is installed on the movable part 108, and the sensing element SE is installed on the first circuit part 1141 of the circuit assembly 114 and faces the sensing magnet MG.

[0035] In addition, in this embodiment, the optical element driving mechanism 100 further includes a control circuit 125 disposed on the second circuit portion 1142. When viewed along the main axis MX, the second circuit portion 1142 shields the control circuit 125. The control circuit 125 is, for example, an integrated circuit or chip electrically connected to an external circuit and configured to control the operation of the drive assembly DA in accordance with signals from the external circuit.

[0036] 2, the receiving space 1023 has a first receiving space RS1, which is located on a first side SS1 when viewed along the main axis MX. In particular, the first receiving space RS1 is defined by a dividing wall 112W and the casing 102, and the dividing wall 112W is located between the first receiving space RS1 and the drive assembly DA.

[0037] In this embodiment, the control circuit 125 is accommodated in the first accommodation space RS1, but is not limited to this. In other embodiments, a part of the circuit assembly 114 or the sensing element SE can be accommodated in the first accommodation space RS1.

[0038] In this embodiment, as shown in Figures 2 and 3, the drive assembly DA is electrically connected to the circuit assembly 114 and operates in accordance with a control signal from the control circuit 125 on the circuit assembly 114 to move the movable part 108 along the main axis MX (or the optical axis O).

[0039] 2 and 3, the drive assembly DA includes an enhancement element PA1, a drive element PA2, and a transmission element PA3. The transmission element PA3 has an elongated structure (e.g., a columnar structure) and is made of, but not limited to, a carbon material.

[0040] The enhancing element PA1 may be, for example, but not limited to, a counterweight. In other embodiments, the enhancing element PA1 may be an elastic piece. The driving element PA2 may be, for example, a piezoelectric element, and is fixedly connected between the enhancing element PA1 and the transmitting element PA3. In this embodiment, the driving element PA2 comprises a piezoelectric material. For example, but not limited to, the driving element PA2 may be made of a ceramic material.

[0041] The driving element PA2 is configured to generate a first driving force, the enhancing element PA1 corresponds to the driving element PA2 and is configured to enhance the first driving force, and the transmission element PA3 is configured to transmit the first driving force. As shown in Figure 4, when viewed along the main axis MX, the extension direction ED1 of the transmission element PA3 is parallel to the first side SS1.

[0042] Furthermore, the optical element driving mechanism 100 further includes an intermediate assembly TA configured to transmit a first driving force to the movable part 108. That is, the first driving force is transmitted to the movable part 108 by the transmission element PA3 and the intermediate assembly TA to move the movable part 108 along the main axis MX, thereby achieving the purpose of autofocus.

[0043] 2 and 3, the intermediate assembly TA corresponds to the transmission element PA3 of the drive assembly DA and has two contact members 106 that contact the transmission element PA3. The intermediate assembly TA further has a force applying member 107 that applies a supporting force to the two contact members 106, and the contact members 106 sandwich the transmission element PA3. In this embodiment, the contact members 106 are, for example, elastic metal pieces, and the force applying member 107 is, for example, a rubber sleeve, but are not limited thereto.

[0044] Additionally, the intermediate assembly TA further includes a first conductive member 103, a second conductive member 105, a first fixation element 1081, and a second fixation element 109. The first fixation element 1081 is configured to fix the first conductive member 103, and the second fixation element 109 is configured to fix the second conductive member 105.

[0045] In this embodiment, the first fixed element 1081 can be a part of the movable part 108. For example, but not limited to, the first fixed element 1081 and the movable part 108 are integrally molded. The second fixed element 109 has a frame-shaped structure and is configured to surround the force applying member 107. In particular, the force applying member 107 is fixedly connected to the second fixed element 109 and is located between the transmission element PA3 and the second fixed element 109.

[0046] Furthermore, the second conductive member 105 corresponds to the first conductive member 103, and the second conductive member 105 is movable relative to the first conductive member 103, and the first conductive member 103 is movable relative to the transmission element PA3, and the second conductive member 105 is movable relative to the transmission element PA3.

[0047] In particular, the second conducting member 105 has a first groove 111, and the first conducting member 103 passes through the first groove 111 and is positioned within the first groove 111. Based on this arrangement, the first driving force is configured to be transmitted to the movable part 108 via the contact member 106, the force application member 107, the second fixed element 109, the second conducting member 105, and the first conducting member 103. The specific operating method will be described in the following paragraphs.

[0048] In this embodiment, the Young's moduli of the first conductive member 103 and the second conductive member 105 are different. For example, but not limited to, the first conductive member 103 includes a metal material and the second conductive member 105 includes a plastic material, such as a resin material.

[0049] 5 to 7. Fig. 5 is a front view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present invention. Fig. 6 is a front view of a second conductive member 105 in a first position according to an embodiment of the present invention. Fig. 7 is a front view of a second conductive member 105 in a second position according to an embodiment of the present invention.

[0050] As shown in FIG. 5, when the driving element PA2 generates a first driving force, the first driving force is transmitted to the second fixed element 109 by the transmission element PA3, the contact member 106, and the force application member 107, so that the second fixed element 109 can move back and forth between a first position P1 and a second position P2 along the first axis AX1.

[0051] Accordingly, as shown in Figures 5 and 6, when the second fixed element 109 is located in the first position P1, the second conductive member 105 is also located in the first position P1 accordingly, and the second conductive member 105 positions the first conductive member 103 and the movable part 108 in the first extreme position in Figure 6.

[0052] On the other hand, as shown in Figures 5 and 7, when the second fixed element 109 moves from the first position P1 to the second position P2, the second conductive member 105 also moves accordingly to be located at the second position P2, and the second conductive member 105 moves the first conductive member 103 and the movable part 108 from the first extreme position in Figure 6 to the second extreme position in Figure 7.

[0053] Meanwhile, the second conductive member 105 can also move the first conductive member 103 and the movable part 108 from the second extreme position in Fig. 7 to the first extreme position in Fig. 6. Based on this arrangement, the movable part 108 can move the optical element OE along the main axis MX to achieve the purpose of autofocus.

[0054] 2 and 4, in this embodiment, the optical element driving mechanism 100 further includes a protective element 110 fixedly installed on a base 112 of the fixing assembly FA. The protective element 110 is made of a metal material and has a columnar structure, for example, a cylindrical structure. The protective element 110 extends along the main axis MX and passes through the movable part 108.

[0055] 2 and 4, the protective element 110 is disposed adjacent to the first conductive member 103. In particular, as shown in Fig. 4, when viewed along the main axis MX, a first quadrant Q1, a second quadrant Q2, a third quadrant Q3, and a fourth quadrant Q4 are defined with the main axis MX as the origin, and when viewed along the main axis MX, the protective element 110 and the first conductive member 103 are located in the fourth quadrant Q4.

[0056] Based on the structural design and positional arrangement of the protective element 110, the first driving force transmitted by the transmission element PA3 is ensured to be accurately transmitted to the movable part 108 by the second fixed element 109, the second conducting member 105, and the first conducting member 103, thereby achieving the highest driving efficiency.

[0057] Next, referring to Figures 2, 4 to 7 continuously, as shown in Figures 6 and 7, since the first conductive member 103 is installed on the right side of the movable part 108, when the drive assembly DA moves the movable part 108 along the main axis MX, the left side of the movable part 108 tilts toward the bottom of the base 112, making the image unclear.

[0058] To avoid the above situation, as shown in Figures 2 and 4, the optical element driving mechanism 100 further includes a guide element 120 and a first stable element 130 to avoid the problem of tilting of the movable part 108 during movement. As shown in Figures 2 and 4, the guide element 120 is fixedly installed on a base 112 of the fixed assembly FA.

[0059] Similarly, the guide element 120 has a columnar structure, e.g., a cylindrical structure, extending along the main axis MX, and the guide element 120 is configured to pass through the movable part 108. Furthermore, the first stable element 130 is fixedly installed on the movable part 108 and corresponds to the guide element 120.

[0060] 4, when viewed along the main axis MX, the movable part 108 has a rectangular structure. When viewed along the main axis MX, the guide element 120 and the first stable element 130 are located at corners CR1 of the rectangular structure. In particular, when viewed along the main axis MX, the guide element 120 and the first stable element 130 are located in the second quadrant Q2.

[0061] Furthermore, as shown in FIG. 4, when viewed along the major axis MX, the first stable element 130 and the guide element 120 are arranged in sequence along the diagonal DL of the rectangular structure.

[0062] In this embodiment, the first stable element 130 comprises a magnetic material. For example, the first stable element 130 is a magnet, and the first stable element 130 corresponds to the guide element 120. For example, the guide element 120 is made of a magnetic material, for example, a metal material.

[0063] A magnetic attraction force MF1 is generated between the guide element 120 and the first stable element 130, allowing the first stable element 130 to push the movable part 108 along the diagonal line DL (shown by the arrow in Figure 4), and the inner wall surface of the perforation PH1 of the movable part 108 can come into contact with the guide element 120, increasing the friction force between the movable part 108 and the guide element 120.

[0064] Based on this design, the above-mentioned friction force can avoid the above-mentioned tilt problem of the movable part 108 during movement, and the friction force does not affect the smoothness of the movable part 108 along the main axis MX, thereby improving the imaging accuracy of the optical element driving mechanism 100.

[0065] 6 and 7, the optical element driving mechanism 100 further includes a stop assembly PA configured to limit movement of the movable part 108 within its range of motion. At least a portion of the stop assembly PA is mounted on the movable part 108. For example, the stop assembly PA includes a first stop structure 1085 and a second stop structure 1086 mounted on the movable part 108.

[0066] In particular, the first stop structure 1085 and the second stop structure 1086 are disposed on opposite sides of the movable part 108. As shown in Fig. 6, when the movable part 108 is in a first extreme position, the first stop structure 1085 is configured to contact the base 112. On the other hand, as shown in Fig. 7, when the movable part 108 is in a second extreme position, the second stop structure 1086 is configured to contact the casing 102.

[0067] Continuing with reference to Figures 8 and 9, Figure 8 is a three-dimensional exploded view of a partial structure of optical element driving mechanism 100 according to an embodiment of the present invention. Figure 9 is a front view of a partial structure of optical element driving mechanism 100 according to an embodiment of the present invention. As shown in Figures 8 and 9, the first fixed element 1081 is a part of the movable part 108, such as a corner part of the movable part 108 having a first surface SF1, a first receiving portion ASP1, and a second surface SF2.

[0068] The first surface SF1 faces the second conducting member 105, and the first receiving portion ASP1 has an opening structure formed on the first surface SF1 and configured to receive at least a portion of the first conducting member 103.

[0069] In particular, in this embodiment, the first conducting member 103 has an elongated structure extending along the first direction D1, and the first receiving portion ASP1 is a cylindrical hole recessed from the first surface SF1 along the first direction D1. The first conducting member 103 is detachably attached to the first receiving portion ASP1.

[0070] 8, the second surface SF2 is not parallel to the first surface SF1, but is, for example, perpendicular to the first surface SF1. Furthermore, the optical element driving mechanism 100 further includes a first opening HP1 and a second opening HP2. The first opening HP1 is formed in the second surface SF2, and the first opening HP1 can communicate with the first receiving portion ASP1. At least a portion of the first conductive member 103 is exposed through the first opening HP1.

[0071] 9, the optical element driving mechanism 100 further includes a first connecting element AE1 partially located in the first receiving portion ASP1. The first connecting element AE1 may be, for example, but is not limited to, a light-curable gel or a heat-curable gel. The first conductive member 103 is connected to the first fixing element 1081 by the first connecting element AE1.

[0072] 9, a first gap GP1 is formed between the first conducting member 103 and the first receiving portion ASP1. That is, when viewed along the first direction D1 (e.g., parallel to the Y-axis), the diameter of the first receiving portion ASP1 is larger than the diameter of the first conducting member 103, for example, by 5 to 10%.

[0073] Based on this arrangement, at least a portion of the first connecting element AE1 is located in the first gap GP1, so that the first conductive member 103 can be conveniently and effectively placed in the first receiving portion ASP1.

[0074] 8, the optical element driving mechanism 100 further includes a second connecting element AE2 partially located in the first opening HP1. The second connecting element AE2 directly contacts the first conductive member 103 and the first fixing element 1081, and the second connecting element AE2 directly contacts the first connecting element AE1.

[0075] The second connecting element AE2 may be, for example, but not limited to, a light-curing gel or a heat-curing gel. Based on the arrangement of the first opening HP1, when an operator installs the first conducting member 103, the operator can observe and confirm whether the first conducting member 103 is accurately attached to the movable part 108, thereby improving the convenience of installation.

[0076] 8 and 9, a second opening HP2 is formed on the first surface SF1 and adjacent to the first receiving portion ASP1. For example, the second opening HP2 communicates with the first receiving portion ASP1. Similarly, the optical element driving mechanism 100 further includes a third connecting element AE3, and at least a portion of the third connecting element AE3 is located in the second opening HP2.

[0077] The third connecting element AE3 may be, for example, but not limited to, a light-curing gel or a heat-curing gel. The third connecting element AE3 is in direct contact with the first conductive member 103 and the first fixing element 1081, and is in direct contact with the first connecting element AE1.

[0078] Based on this arrangement, an operator can easily install the third connecting element AE3 on the second opening HP2 on both sides of the first conductive member 103, and then fix the first conductive member 103 on the movable part 108.

[0079] It should be noted that the third connecting element AE3 can completely fill the second opening HP2 but does not extend beyond the first surface SF1, which ensures that the third connecting element AE3 does not come into contact with the second conducting member 105 and thus does not affect the movement of the second conducting member 105.

[0080] In addition, in this embodiment, the first connecting element AE1, the second connecting element AE2, and the third connecting element AE3 are made of the same material. For example, but not limited to, these connecting elements have the same physical properties, such as the same Young's modulus. In other embodiments, these connecting elements can be made of different materials according to actual requirements.

[0081] Next, please refer to Figures 8 and 10. Figure 10 is a front view of a partial structure of an optical element driving mechanism 100 according to one embodiment of the present invention. In this embodiment, as shown in Figures 8 and 10, the second conductive member 105 has a third surface SF3 and the above-mentioned first groove 111, and the first groove 111 is recessed from the third surface SF3. In particular, the first groove 111 penetrates the third surface SF3.

[0082] 10 , second conductive member 105 of intermediate assembly TA further has a first corresponding surface 1111 and a second corresponding surface 1112. First corresponding surface 1111 faces first conductive member 103, and second corresponding surface 1112 faces first conductive member 103.

[0083] 10, when viewed along a first direction D1, the first conducting member 103 is located between a first corresponding surface 1111 and a second corresponding surface 1112. The first corresponding surface 1111 and the second corresponding surface 1112 face in different directions, and the first corresponding surface 1111 and the second corresponding surface 1112 are formed in a first groove 111. The first corresponding surface 1111 is parallel to the second corresponding surface 1112, but this is not required.

[0084] In this embodiment, the first groove groove 111 has an elongated structure, and the first groove groove 111 further has a first end 1113 and a second end 1114, the first corresponding surface 1111 is located between the first end 1113 and the second end 1114, and the second corresponding surface 1112 is located between the first end 1113 and the second end 1114.

[0085] In particular, the first corresponding surface 1111 is connected between the first end 1113 and the second end 1114, and the second corresponding surface 1112 is connected between the first end 1113 and the second end 1114. Thus, as shown in FIG. 10 , the first groove 111 is formed by the first corresponding surface 1111, the second corresponding surface 1112, the first end 1113, and the second end 1114.

[0086] It should be noted that when the second conducting member 105 moves, the first conducting member 103 contacts the first corresponding surface 1111 and the second corresponding surface 1112. In addition, when the first conducting member 103 positions the movable part 108 at any position within its range of motion, the first conducting member 103 does not contact the first end 1113, and when the first conducting member 103 positions the movable part 108 at any position within its range of motion, the first conducting member 103 does not contact the second end 1114.

[0087] Continuing with reference to Figures 8 and 10, in this embodiment, the second conductive member 105 further includes a first positioning portion 1051, and the first positioning portion 1051 includes a first positioning surface 1052. The first positioning surface 1052 is not parallel to the third surface SF3. For example, the first positioning surface 1052 is perpendicular to the third surface SF3.

[0088] Similarly, the second conductive member 105 further includes a second locating portion 1053, and the second locating portion 1053 includes a second locating surface 1054. The second locating surface 1054 is not parallel to the third surface SF3. For example, the second locating surface 1054 is perpendicular to the third surface SF3.

[0089] In this embodiment, the second positioning surface 1054 and the first positioning surface 1052 face in different directions, in particular, the second positioning surface 1054 and the first positioning surface 1052 are opposite each other.

[0090] Based on this arrangement, the first positioning portion 1051 and the second positioning portion 1053 sandwich the second fixing element 109, so that the second fixing element 109 can be positioned between the first positioning portion 1051 and the second positioning portion 1053.

[0091] Furthermore, the optical element driving mechanism 100 further includes a fourth connecting element AE4, and the second conductive member 105 is connected to the second fixing element 109 by the fourth connecting element AE4. The fourth connecting element AE4 is, for example, but is not limited to, a photocurable gel or a heat curable gel.

[0092] The fourth connecting element AE4 is in direct contact with the third surface SF3, the fourth connecting element AE4 is in direct contact with the first positioning surface 1052, and the fourth connecting element AE4 is in direct contact with the second positioning surface 1054, so that the second fixing element 109 is fixed to the second conductive member 105.

[0093] Based on the above arrangement of the first fixed portion 1051, the second fixed portion 1053, and the fourth connecting element AE4, it can be ensured that the second conductive member 105 does not separate from the second fixed element 109 when the second fixed element 109 moves.

[0094] 2, 11, and 12. Fig. 11 is a three-dimensional cross-sectional view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present invention, taken along line BB in Fig. 1. Fig. 12 is a front view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present invention. In this embodiment, the base 112 has a third positioning portion 1123 protruding along the main axis MX (Z-axis).

[0095] For example, the third positioning portion 1123 is, for example, a rectangular bump, and the third positioning portion 1123 has a third positioning surface 1125. The third positioning surface 1125 is, for example, the top surface of the third positioning portion 1123. The third positioning surface 1125 and the first positioning surface 1052 face in different directions, and the third positioning surface 1125 and the second positioning surface 1054 also face in different directions.

[0096] Similarly, third locating surface 1125 is not parallel to third surface SF3. For example, but not limited to, third locating surface 1125 is perpendicular to third surface SF3. Because there is a gap between second conducting member 105 and third locating surface 1125, second conducting member 105 can move relative to third locating surface 1125.

[0097] It should be noted that the fourth connecting element AE4 does not contact the third positioning surface 1125. That is, the fourth connecting element AE4 does not affect the movement of the second conducting member 105. In addition, the arrangement of the third positioning portion 1123 increases the convenience of the operator when installing the second conducting member 105.

[0098] In addition, in this embodiment, the second conductive member 105 further includes a fourth positioning portion 1057 extending from the third surface SF3, and the fourth positioning portion 1057 includes a fourth positioning surface 1058. The fourth positioning surface 1058 is, for example, the bottom surface of the fourth positioning portion 1057, but is not limited to this.

[0099] As shown in FIG. 11, the fourth positioning surface 1058 and the first positioning surface 1052 face in different directions, the fourth positioning surface 1058 and the second positioning surface 1054 face in different directions, the fourth positioning surface 1058 and the third positioning surface 1125 face in different directions, and the fourth positioning surface 1058 is not parallel to the third surface SF3.

[0100] As shown in FIG. 12, when viewed in a direction perpendicular to the third surface SF3, for example, when viewed along the Y axis, the transmission element PA3 is located between the third positioning surface 1125 and the fourth positioning surface 1058.

[0101] Next, please refer to Figures 13 and 14. Figure 13 is an exploded view of a partial structure of an optical element driving mechanism 100 according to another embodiment of the present invention. Figure 14 is a cross-sectional view of a partial structure of an optical element driving mechanism 100 according to another embodiment of the present invention taken along line CC in Figure 13. In this embodiment, the intermediate assembly TA further includes a second groove groove 113. The second groove groove 113 has a recessed structure formed on the second fixing element 109.

[0102] In this embodiment, the second groove 113 does not penetrate the second fixing element 109, but this is not limited thereto. In other embodiments, the second groove 113 is an open structure that penetrates the second fixing element 109.

[0103] Furthermore, the second groove 113 on the second fixing element 109 has a third corresponding surface 1131 facing the first conductive member 103, and the second groove 113 further has a fourth corresponding surface 1132 facing the first conductive member 103.

[0104] 13, when viewed along the extension direction of first conducting member 103, for example, when viewed along second direction D2, after assembly, first conducting member 103 is located between third corresponding surface 1131 and fourth corresponding surface 1132. Second direction D2 is opposite to first direction D1.

[0105] In this embodiment, the third corresponding surface 1131 is parallel to the first corresponding surface 1111, and the fourth corresponding surface 1132 is parallel to the second corresponding surface 1112. For example, but not limited to, the second groove groove 113 has the same contour as the first groove groove 111.

[0106] 14, it should be noted that the third corresponding surface 1131 is not connected to the first corresponding surface 1111, and the fourth corresponding surface 1132 is not connected to the second corresponding surface 1112. That is, there is a gap GP2 between the third corresponding surface 1131 and the first corresponding surface 1111, and there is also the above-mentioned gap GP2 between the fourth corresponding surface 1132 and the second corresponding surface 1112.

[0107] In summary, the present invention provides an optical element drive mechanism 100 having a fixed assembly FA, ​​a movable part 108, and a drive assembly DA. The movable part 108 is movable relative to the fixed assembly FA, ​​and the drive assembly DA is configured to move the movable part 108 relative to the fixed assembly FA. Furthermore, the optical element drive mechanism 100 further includes an intermediate assembly TA, and the drive assembly DA moves the movable part 108 via the intermediate assembly TA.

[0108] In some embodiments, the intermediate assembly TA includes a first conducting member 103, a second conducting member 105, and a second stationary element 109. The first conducting member 103 is fixedly connected to the movable part 108, the second conducting member 105 is fixed to the second stationary element 109, and the second stationary element 109 is mounted on a transmission element PA3 of the drive assembly DA. When the drive assembly DA provides a first driving force, the second stationary element 109 moves the second conducting member 105 along the first axis AX1.

[0109] Furthermore, a first groove 111 is formed on the second conductive member 105, and the first conductive member 103 has a cylindrical structure passing through the first groove 111. When the second conductive member 105 moves along the first axis AX, the first conductive member 103 moves the movable member 108 along the main axis MX. The extension direction of the first groove 111 is not parallel to the first axis AX or the main axis MX. In addition, in some embodiments, the positions of the first conductive member 103 and the first groove 111 are interchangeable. For example, the first conductive member 103 is mounted on the second fixed element 109, and the first groove 111 is formed on the movable member 108. This effectively reduces the structural dimension of the optical element driving mechanism 100 along the main axis MX, thereby achieving the goal of miniaturization.
