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

[0003] The design of today's electronic devices is constantly developing towards the trend of miniaturization, so that various components or structures of camera modules must also be continuously reduced to achieve the purpose of miniaturization.

[0145] In this embodiment, the Young's modulus of the first conductive element 103 and the second conductive element 105 are different. For example, the first conductive element 103 may be made of metal material, and the second conductive element 105 may be made of plastic material, such as resin material, but not limited thereto.

[0146] Please refer to Figures 5 to 7 . Figure 5 FIG. 1 is a front view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present utility model. Figure 6 is a front view schematic diagram of a second conducting element 105 located at a first position according to an embodiment of the present invention, and Figure 7 FIG. 1 is a front view of a second conductive element 105 located at a second position according to an embodiment of the present invention.

[0147] like Figure 5 As shown, when the driving element PA2 generates a first driving force, the first driving force can be transmitted to the second fixing element 109 via the transmission element PA3, the contact element 106 and the force applying element 107, so that the second fixing element 109 can move back and forth between a first position P1 and a second position P2 along a first axial direction AX1.

[0148] Correspondingly, if Figure 5 and Figure 6 As shown, when the second fixing element 109 is located at the first position P1, the second conducting element 105 is also correspondingly located at the first position P1, and the second conducting element 105 drives the first conducting element 103 and the movable portion 108 to be located at Figure 6 A first extreme position in.

[0149] On the other hand, Figure 5 and Figure 7As shown, when the second fixing element 109 moves from the first position P1 to the second position P2, the second conducting element 105 also moves correspondingly to the second position P2, and the second conducting element 105 drives the first conducting element 103 and the movable portion 108 to move from the first position P1 to the second position P2. Figure 6 The first limit position moves to Figure 7 A second extreme position in.

[0150] Conversely, the second conductive element 105 can also drive the first conductive element 103 and the movable portion 108 to Figure 7 The second limit position moves to Figure 6 Based on such a configuration, the movable portion 108 can drive the optical element OE to move along the direction of the main axis MX to achieve the purpose of automatic focusing.

[0151] In addition, if Figure 2 and Figure 4 As shown, in this embodiment, the optical element driving mechanism 100 may further include a protection element 110, which is fixedly disposed on a base 112 of the fixing assembly FA. The protection element 110 may be made of a metal material and has a columnar structure, such as a cylindrical structure. The protection element 110 extends along the main axis MX and passes through the movable portion 108.

[0152] like Figure 2 and Figure 4 As shown in FIG. 1 , the protection element 110 is disposed adjacent to the first conductive element 103. Specifically, as Figure 4 As shown, when observed along the main axis MX, a first quadrant Q1, a second quadrant Q2, a third quadrant Q3 and a fourth quadrant Q4 can be defined with the main axis MX as the origin, and when observed along the main axis MX, the protection element 110 and the first conductive element 103 are located in the fourth quadrant Q4.

[0153] Based on the structural design and position configuration of the protection element 110 , it can be ensured that the first driving force transmitted by the transmission element PA3 can be transmitted to the movable part 108 via the second fixing element 109 , the second conducting element 105 and the first conducting element 103 to achieve optimal driving efficiency.

[0154] Then continue to refer to Figure 2 , Figures 4 to 7 .like Figure 6 as well as Figure 7 As shown, since the first conducting element 103 is disposed on the right side of the movable part, when the driving assembly DA drives the movable part 108 to move along the main axis MX, the left side of the movable part 108 may tilt toward the bottom of the base 112, thereby causing unclear images.

[0155] To avoid the above situation, Figure 2 and Figure 4 As shown, the optical element driving mechanism 100 further includes a guiding element 120 and a first stabilizing element 130 to prevent the movable portion 108 from tilting during movement. Figure 2 and Figure 4 As shown, the guide element 120 is fixedly disposed on the base 112 of the fixing assembly FA.

[0156] Similarly, the guide element 120 has a columnar structure, such as a cylindrical structure, extending along the main axis MX, and the guide element 120 is configured to pass through the movable portion 108. Furthermore, the first stabilizing element 130 is fixedly disposed on the movable portion 108, corresponding to the guide element 120.

[0157] like Figure 4 As shown, when viewed along the main axis MX, the movable portion 108 may have a rectangular structure. When viewed along the main axis MX, the guide element 120 and the first stabilizing element 130 are located at a corner CR1 of the rectangular structure. Specifically, when viewed along the main axis MX, the guide element 120 and the first stabilizing element 130 are located in the second quadrant Q2.

[0158] Furthermore, if Figure 4 As shown, when viewed along the main axis MX, the first stabilizing element 130 and the guiding element 120 are sequentially arranged along a diagonal line DL of the rectangular structure.

[0159] In this embodiment, the first stabilizing element 130 has a magnetic material. For example, the first stabilizing element 130 is a magnet, and the first stabilizing element 130 corresponds to the guiding element 120. For example, the guiding element 120 can be made of a magnetic material, such as a metal material.

[0160] A magnetic attraction force MF1 can be generated between the guiding element 120 and the first stabilizing element 130, so that the first stabilizing element 130 pushes the movable portion 108 along the diagonal line DL (eg Figure 4 As shown by the arrow in the figure), the inner wall surface of a through hole PH1 of the movable portion 108 can be supported on the guiding element 120 to increase the friction between the movable portion 108 and the guiding element 120.

[0161] Based on such a design, the friction force can prevent the movable part 108 from tilting during movement, and the friction force does not affect the smoothness of the movement of the movable part 108 along the main axis MX, thereby improving the accuracy of the optical element driving mechanism 100 during imaging.

[0162] In addition, if Figure 6 and Figure 7As shown, the optical element driving mechanism 100 further includes a stopper assembly PA configured to limit the movable portion 108 to move within a range of motion. At least a portion of the stopper assembly PA is disposed on the movable portion 108. For example, the stopper assembly PA may include a first stopper structure 1085 and a second stopper structure 1086 disposed on the movable portion 108.

[0163] Specifically, the first stop structure 1085 and the second stop structure 1086 are disposed on opposite sides of the movable portion 108. Figure 6 As shown, when the movable portion 108 is located at a first limit position, the first stop structure 1085 can be configured to abut against the base 112. Figure 7 As shown, when the movable portion 108 is located at a second limit position, the second stopping structure 1086 can be configured to abut against the housing 102 .

[0164] Please continue to refer to Figure 8 and Fig. 9 . Figure 8 is a three-dimensional exploded view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present invention, and Fig. 9 FIG. 1 is a front view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present utility model. Figure 8 and Fig. 9 As shown, the first fixing element 1081 is a part of the movable portion 108, such as a corner portion of the movable portion 108, and includes a first surface SF1, a first receiving portion ASP1 and a second surface SF2.

[0165] The first surface SF1 faces the second conductive element 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 conductive element 103 .

[0166] Specifically, in this embodiment, the first conductive element 103 has a long strip structure extending along a first direction D1, and the first receiving portion ASP1 can be a cylindrical hole formed by the first surface SF1 being recessed along the first direction D1. The first conductive element 103 is detachably installed in the first receiving portion ASP1.

[0167] Furthermore, if Figure 8 As shown, the second surface SF2 is not parallel to the first surface SF1, 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, wherein the first opening HP1 is formed on the second surface SF2, and the first opening HP1 can be connected to the first receiving portion ASP1. At least a portion of the first conductive element 103 can be exposed from the first opening HP1.

[0168] like Fig. 9 As shown, the optical element driving mechanism 100 may further include a first connecting element AE1, partially located in the first receiving portion ASP1, the first connecting element AE1 is, for example, light-curing glue or thermosetting glue, but is not limited thereto. The first conducting element 103 may be connected to the first fixing element 1081 via the first connecting element AE1.

[0169] It is worth noting that Fig. 9 As shown, a first gap GP1 may be formed between the first conductive element 103 and the first receiving portion ASP1. That is, when viewed along the first direction D1 (eg, parallel to the Y axis), the diameter of the first receiving portion ASP1 is greater than the diameter of the first conductive element 103, for example, greater than 5 to 10%.

[0170] Based on such a configuration, at least a portion of the first connecting element AE1 can be located in the first gap GP1, so as to conveniently and effectively install the first conductive element 103 in the first receiving portion ASP1.

[0171] Similarly, Figure 8 As shown, the optical element driving mechanism 100 may further include a second connecting element AE2, which is partially located in the first opening HP1. The second connecting element AE2 directly contacts the first conductive element 103 and the first fixing element 1081, and the second connecting element AE2 directly contacts the first connecting element AE1.

[0172] The second connection element AE2 is, for example, light-curing glue or thermosetting glue, but is not limited thereto. Based on the configuration of the first opening HP1, the operator can observe and confirm whether the first conductive element 103 is accurately installed on the movable part 108 when installing the first conductive element 103, so as to increase the convenience during installation.

[0173] Furthermore, if Figure 8 and Fig. 9 As shown, the second opening HP2 is formed on the first surface SF1 and adjacent to the first receiving portion ASP1. For example, the second opening HP2 is connected to the first receiving portion ASP1. Similarly, the optical element driving mechanism 100 may further include a third connecting element AE3, and at least a portion of the third connecting element AE3 is located in the second opening HP2.

[0174] The third connection element AE3 is, for example, light-curing glue or thermosetting glue, but is not limited thereto. The third connection element AE3 directly contacts the first conductive element 103 and the first fixing element 1081 , and the third connection element AE3 directly contacts the first connection element AE1 .

[0175] Based on such a configuration, the operator can easily dispose the third connecting element AE3 at the second openings HP2 on both sides of the first conductive element 103 to further fix the first conductive element 103 on the movable portion 108 .

[0176] It is worth noting that the third connection element AE3 can completely fill the second opening HP2, but the third connection element AE3 does not extend beyond the first surface SF1. Based on such a configuration, it can be ensured that the third connection element AE3 does not contact the second conductive element 105 to avoid affecting the movement of the second conductive element 105.

[0177] In addition, in this embodiment, the first connecting element AE1, the second connecting element AE2, and the third connecting element AE3 can be made of the same material. For example, these connecting elements can have the same physical properties, such as the same Young's modulus, but not limited thereto. In other embodiments, these connecting elements can be made of different materials to meet actual needs.

[0178] Please refer to Figure 8 and Fig.10 , Fig.10 FIG. 1 is a front view of a partial structure of an optical element driving mechanism 100 according to an embodiment of the present utility model. Figure 8 and Fig.10 As shown, the second conductive element 105 has a third surface SF3 and the aforementioned first trench 111, and the first trench 111 is recessed from the third surface SF3. Specifically, the first trench 111 penetrates the third surface SF3.

[0179] Furthermore, if Fig.10 As shown, the second conductive element 105 of the intermediate assembly TA may further include a first corresponding surface 1111 and a second corresponding surface 1112 , wherein the first corresponding surface 1111 faces the first conductive element 103 , and the second corresponding surface 1112 faces the first conductive element 103 .

[0180] like Fig.10 As shown, when viewed along the first direction D1, the first conductive element 103 is located between the first corresponding surface 1111 and the second corresponding surface 1112, the first corresponding surface 1111 and the second corresponding surface 1112 face different directions, and the first corresponding surface 1111 and the second corresponding surface 1112 are formed in the first groove 111. The first corresponding surface 1111 may be parallel to the second corresponding surface 1112, but is not limited thereto.

[0181] In this embodiment, the first groove 111 has a long strip structure, and the first groove 111 may further have 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.

[0182] Specifically, 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. Fig.10 As shown, the first groove 111 may be formed by a first corresponding surface 1111 , a second corresponding surface 1112 , a first end 1113 and a second end 1114 .

[0183] It is worth noting that when the second conductive element 105 moves, the first conductive element 103 contacts the first corresponding surface 1111 and the second corresponding surface 1112. In addition, when the first conductive element 103 drives the movable portion 108 to be located at any position within the motion range, the first conductive element 103 does not contact the first end portion 1113, and when the first conductive element 103 drives the movable portion 108 to be located at any position within the motion range, the first conductive element 103 does not contact the second end portion 1114.

[0184] Please continue to refer to Figure 8 and Fig.10 In this embodiment, the second conductive element 105 may further include a first positioning portion 1051, and the first positioning portion 1051 has 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.

[0185] Similarly, the second conductive element 105 may further include a second positioning portion 1053, and the second positioning portion 1053 has a second positioning surface 1054. The second positioning surface 1054 is not parallel to the third surface SF3, for example, the second positioning surface 1054 is perpendicular to the third surface SF3.

[0186] In this embodiment, the second positioning surface 1054 and the first positioning surface 1052 face different directions. Specifically, the second positioning surface 1054 and the first positioning surface 1052 are opposite to each other.

[0187] Based on such a configuration, the first positioning portion 1051 and the second positioning portion 1053 can clamp the second fixing element 109 , so that the second fixing element 109 is positioned between the first positioning portion 1051 and the second positioning portion 1053 .

[0188] Furthermore, the optical element driving mechanism 100 may further include a fourth connecting element AE4, and the second conductive element 105 is connected to the second fixing element 109 via the fourth connecting element AE4. The fourth connecting element AE4 is, for example, light-curing glue or thermosetting glue, but is not limited thereto.

[0189] The fourth connecting element AE4 directly contacts the third surface SF3 , the fourth connecting element AE4 directly contacts the first positioning surface 1052 , and the fourth connecting element AE4 directly contacts the second positioning surface 1054 , so that the second fixing element 109 can be fixed to the second conductive element 105 .

[0190] Based on the configuration of the first positioning portion 1051 , the second positioning portion 1053 and the fourth connecting element AE4 , it can be ensured that when the second fixing element 109 moves, the second conducting element 105 will not be separated from the second fixing element 109 .

[0191] Please refer to Figure 2 , Fig.11 as well as Fig.12 . Fig.11 The partial structure of the optical element driving mechanism 100 according to an embodiment of the present invention is shown along Figure 1 A three-dimensional cross-section of the midline segment BB, and Fig.12 FIG. 1 is a front view of a part of the structure of the optical element driving mechanism 100 according to an embodiment of the present invention. In this embodiment, the base 112 may include a third positioning portion 1123 protruding along the main axis MX (Z axis).

[0192] For example, the third positioning portion 1123 is a rectangular protrusion, and the third positioning portion 1123 may have 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 different directions, and the third positioning surface 1125 and the second positioning surface 1054 also face different directions.

[0193] Similarly, the third positioning surface 1125 is not parallel to the third surface SF3, for example, the third positioning surface 1125 is perpendicular to the third surface SF3, but not limited thereto. There is a gap between the second conductive element 105 and the third positioning surface 1125, so the second conductive element 105 can move relative to the third positioning surface 1125.

[0194] It is worth noting 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 conductive element 105. In addition, based on the configuration of the third positioning portion 1123, the convenience of the operator when installing the second conductive element 105 can be increased.

[0195] In addition, in this embodiment, the second conductive element 105 further includes a fourth positioning portion 1057 extending from the third surface SF3 , and the fourth positioning portion 1057 has a fourth positioning surface 1058 .

[0196] The fourth positioning surface 1058 is, for example, a bottom surface of the fourth positioning portion 1057 , but is not limited thereto.

[0197] like Fig.11 As shown, the fourth positioning surface 1058 and the first positioning surface 1052 face different directions, the fourth positioning surface 1058 and the second positioning surface 1054 face different directions, the fourth positioning surface 1058 and the third positioning surface 1125 face different directions, and the fourth positioning surface 1058 is not parallel to the third surface SF3.

[0198] like Fig.12 As shown, when viewed along a direction perpendicular to the third surface SF3 , for example, along the Y-axis direction, the transmission element PA3 is located between the third positioning surface 1125 and the fourth positioning surface 1058 .

[0199] Please refer to Fig.13 as well as Fig.14 . Fig.13 is an exploded view of a partial structure of an optical element driving mechanism 100 according to another embodiment of the present invention, and Fig.14 According to another embodiment of the present invention, an optical element driving mechanism 100 is arranged along Fig.13 A cross-sectional view of a portion of the structure of the center line segment CC. In this embodiment, the intermediate element TA may further include a second groove 113 having a concave structure formed on the second fixing element 109 .

[0200] In this embodiment, the second groove 113 does not penetrate the second fixing element 109 , but the present invention is not limited thereto. In other embodiments, the second groove 113 may also be an open structure, penetrating the second fixing element 109 .

[0201] Furthermore, the second groove 113 on the second fixing element 109 may have a third corresponding surface 1131 facing the first conductive element 103 , and the second groove 113 may further have a fourth corresponding surface 1132 facing the first conductive element 103 .

[0202] like Fig.13As shown, when viewed along the extension direction of the first conductive element 103, for example, along a second direction D2, the first conductive element 103 is located between the third corresponding surface 1131 and the fourth corresponding surface 1132 after assembly. The second direction D2 is opposite to the first direction D1.

[0203] 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, the second groove 113 may have the same profile as the first groove 111, but is not limited thereto.

[0204] It is worth noting that Fig.14 As shown, 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 aforementioned gap GP2 between the fourth corresponding surface 1132 and the second corresponding surface 1112.

[0205] In summary, the present invention provides an optical element driving mechanism 100, comprising a fixed component FA, a movable portion 108 and a driving component DA. The movable portion 108 can move relative to the fixed component FA, and the driving component DA is configured to drive the movable portion 108 to move relative to the fixed component FA. Furthermore, the optical element driving mechanism 100 further comprises an intermediate component TA, and the driving component DA drives the movable portion 108 to move via the intermediate component TA.

[0206] In some embodiments, the intermediate component TA includes a first conductive element 103, a second conductive element 105, and a second fixed element 109. The first conductive element 103 is fixedly connected to the movable portion 108, the second conductive element 105 is fixed to the second fixed element 109, and the second fixed element 109 is sleeved on the transmission element PA3 of the driving component DA. When the driving component DA provides a first driving force, the second fixed element 109 drives the second conductive element 105 to move along the first axial direction AX1.

[0207] Furthermore, a first groove 111 is formed on the second conductive element 105, and the first conductive element 103 has a cylindrical structure and passes through the first groove 111. When the second conductive element 105 moves along the first axial direction AX, the first conductive element 103 will be driven to drive the movable part 108 to move along the main axis MX. The extension direction of the first groove 111 is not parallel to the first axial direction AX or the main axis MX. In addition, in some embodiments, the positions of the first conductive element 103 and the first groove 111 can be interchanged, for example, the first conductive element 103 is disposed on the second fixed element 109, and the first groove 111 is formed on the movable part 108, thereby, the optical element driving mechanism 100 can effectively reduce the structural size in the direction of the main axis MX, and achieve the purpose of miniaturization.
