Description

Technical Field

[0001] The present disclosure 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 current electronic devices (such as smartphones) have functions of taking photos or videos. Through a camera module provided on the electronic device, a user can operate the electronic device to capture various photos.

[0003] The current design of electronic devices is constantly moving towards the trend of miniaturization, so that various components or their structures of the camera module must also be continuously reduced to achieve the purpose of miniaturization. Generally speaking, the driving mechanism in the camera module may have a lens carrier configured to carry a lens, and the driving mechanism may have functions of auto focusing or optical image stabilization. However, although the existing driving mechanisms can achieve the foregoing functions of taking photos or videos, they still cannot meet all requirements.

[0129] In this embodiment, the optical element driving mechanism 10 may have the aforementioned first optical module 100 and a second optical module 200. The second optical module 200 is disposed on the first optical module 100, and the second optical module 200 is configured to carry the imaging module 150. As Figure 1 and Figure 3 shown, in the first optical module 100, the first optical module 100 includes a fixed component FA, a first movable part 108, a first driving component DA1, and a first rotating component 120.

[0130] Among them, the fixed component FA includes an outer cover 102 and a first base 112. The outer cover 102 is configured to be fixedly connected to the first base 112 along a main axis MX to form an accommodation space 1023, which is configured to accommodate the first optical module 100 and a part of the second optical module 200. It should be noted that the circular opening on the outer cover 102 corresponds to the camera module 150, but its shape and size are not limited thereto.

[0131] The first movable part 108 is configured to be connected to the second optical module 200, and the first movable part 108 can move relative to the fixed component FA. Specifically, the second optical module 200 can be fixed to the first movable part 108 by screws, but is not limited thereto.

The first movable part 108 is movably connected to the first base 112 through the first rotating component 120, and the first driving component DA1 drives the first movable part 108 to move through the first rotating component 120.

[0135] Among them, the fixed shaft 230 penetrates through the second base 212 and the second rotating component 220, and the second driving component DA2 drives the second movable part 208 to move through the second rotating component 220. Specifically, the second movable part 208 can rotate around a second rotation axis RX2, and the second rotation axis RX2 can be defined by the fixed shaft 230.

[0136] Next, please refer to Figures 3 to 5 . Figure 4 is a top view of a partial structure of the first optical module 100 according to an embodiment of the present disclosure, and Figure 5 is the first optical module 100 according to an embodiment of the present disclosure along Figure 1Cross-sectional view of the middle line segment A-A. The first optical module 100 further includes a first positioning seat 109 configured to be connected to the first base 112, and the first driving component DA1 is configured to be fixed on the first positioning seat 109. The first base 112 can define a first axis AX1 and a second axis AX2, and the second axis AX2 is perpendicular to the first axis AX1.

[0137] Specifically, the first optical module 100 may further include a first connection component LA1 configured to connect the first driving component DA1 and the first positioning seat 109 to the first base 112. Among them, as Figure 3 and Figure 5 shown, the first connection component LA1 includes a first connection element 106 and a first corresponding part 107. The first connection element 106 is, for example, a screw, and the first corresponding part 107 is, for example, a concave hole, but is not limited thereto. It should be noted that the first corresponding part 107 does not have a thread inside.

[0138] As Figure 5 shown, the first connection element 106 can extend along the first axis AX1 and contact the first positioning seat 109, and the first corresponding part 107 has a groove structure and is configured to accommodate at least a part of the first connection element 106. Among them, the first corresponding part 107 is provided on the first positioning seat 109, but is not limited thereto. In other embodiments, the first corresponding part 107 can also be provided on the first base 112.

[0139] Furthermore, the first connection component LA1 may further include a second corresponding part 111. The second corresponding part 111 has an opening structure and is configured to contact the first connection element 106, and the second corresponding part 111 is formed on a first fixing surface 1124 of the first base 112. Specifically, the second corresponding part 111 penetrates the first fixing surface 1124.

[0140] Similarly, the first connection component LA1 further includes a second connection element 110 extending along the first axis AX1, and the first positioning seat 109 correspondingly has a first positioning hole 1091, so that the second connection element 110 passes through the first positioning hole 1091 of the first positioning seat 109 and the first driving component DA1 to connect the first positioning seat 109 and the first driving component DA1 (in a screwed manner).

[0141] Furthermore, as Figures 3 to 5 shown, the first base 112 has a first accommodation space AS1 configured to accommodate at least a part of the first driving component DA1 and the first positioning seat 109. In this embodiment, the first driving component DA1 has a first conduction component 104, a first contact piece 105, and a first power source 114.

[0142] The first conduction component 104 is configured to generate a first driving force. In this embodiment, the first conduction component 104 has an elastic structure that can flex to output the first driving force. Specifically, the first power source 114 can be a first piezoelectric element configured to generate deformation to push the first conduction component 104, so that the first conduction component 104 flexes to output the first driving force.

[0143] The first contact member 105 has a semi-cylindrical structure and is fixedly disposed on the first conduction component 104 and configured to conduct the first driving force. The first rotating component 120 is disposed on the first base 112, and a part of the first rotating component 120 is configured to move relative to the first contact member 105.

[0144] Specifically, when the first conduction component 104 flexes, it can drive the first contact member 105 to move along an elliptical trajectory (when viewed along the main axis MX), and then repeatedly contact and drive a part of the first rotating component 120 to move. The actuation mode of the first conduction component 104 and the first contact member 105 can refer to Chinese Patent Application No. 202420942976.X, so it will not be elaborated here.

[0145] Furthermore, as Figures 3 to 5 shown, the first rotating component 120 is sleeved on a positioning convex portion 112P of the first base 112, and the first rotating component 120 has a first stator 121, a first rotor 122, and a plurality of first balls 123. The first stator 121 is located between the positioning convex portion 112P and the first rotor 122, and these first balls 123 are located between the first stator 121 and the first rotor 122, so that the first rotor 122 can rotate relative to the first stator 121.

[0146] The first movable portion 108 is fixedly connected to the first rotor 122, and the first contact member 105 pushes the first rotor 122 to rotate relative to the first stator 121 around the first rotation axis RX1 according to the aforementioned first driving force, so that the first movable portion 108 drives the second optical module 200 to rotate around the first rotation axis RX1. The first rotation axis RX1 can be defined by the positioning convex portion 112P.

[0147] Please continue to refer to Figures 3 to 6 . Figure 6 is a top view schematic diagram of the second optical module 200 and the first movable portion 108 being driven to be in different positions according to an embodiment of the present disclosure. In this embodiment, the first optical module 100 further has a first stopper 141 and a second stopper 142, which are fixedly disposed on the first base 112.

[0148] The first stopper 141 and the second stopper 142 are, for example, cylindrical bodies that extend along the main axis MX, and the first stopper 141 and the second stopper 142 can be made of a metal material, while the first movable part 108 can be made of a plastic material, but is not limited thereto.

[0149] As Figure 6 shown, when the first movable part 108 is driven by the first driving component DA1 to rotate along a first rotation direction RD1 (clockwise rotation), the first movable part 108 is configured to abut against the first stopper 141. When the first movable part 108 abuts against the first stopper 141, the position of the first movable part 108 can be referred to as a first limit position P1.

[0150] Conversely, when the first movable part 108 is driven by the first driving component DA1 to rotate along a second rotation direction RD2, the first movable part 108 is configured to abut against the second stopper 142. When the first movable part 108 abuts against the second stopper 142, the position of the first movable part 108 can be referred to as a second limit position P2. Among them, the second rotation direction RD2 is opposite to the first rotation direction RD1.

[0151] In addition, as Figure 3 and Figure 4 shown, the first optical module 100 further includes a magnetic element MG and a sensing element SE. The magnetic element MG is fixedly disposed at the bottom of the first movable part 108, and the sensing element SE is disposed on the first base 112. The sensing element SE is configured to sense the magnetic field change of the magnetic element MG to obtain the position of the first movable part 108 relative to the first base 112.

[0152] In this embodiment, the magnetic element MG may have a semi-circular arc structure and include a plurality of magnetic poles, such as a multi-pole magnet, and the sensing element SE is, for example, a Hall sensor or a tunneling magnetoresistance sensor (TMR sensor), but is not limited thereto.

[0153] Next, as Figures 3 to 5 shown, the first accommodation space AS1 may have a first avoidance space AP1 corresponding to the first conduction component 104. The first avoidance space AP1 is, for example, an opening, and a part of the first conduction component 104 is located in the first avoidance space AP1. Based on the configuration of the first avoidance space AP1, the problem of damage caused by the collision between the first conduction component 104 and the first base 112 when the first conduction component 104 flexes can be avoided.

[0154] It should be noted that in this embodiment, the first connecting element 106 is configured to adjust the positions of the first positioning seat 109 and the first driving assembly DA1 on the first axial direction AX1 (Y-axis), so as to further adjust the pre-pressure applied by the first contact element 105 to the first rotating assembly 120, ensuring that the first contact element 105 can correctly drive the first rotating assembly 120. The pre-pressure is, for example, less than or equal to 100 grams, but is not limited thereto.

[0155] Furthermore, as Figure 3 shown in Figure 4 the figure, the first base 112 further has a first receiving surface 1121, which is disposed in the first receiving space AS1, configured to carry a part of the first positioning seat 109, and the first avoiding space AP1 is adjacent to the first receiving surface 1121.

[0156] It should be noted that when observing along the main axis MX, the area of the first receiving surface 1121 may be smaller than the area of the first positioning seat 109. For example, the width of the first receiving surface 1121 on the first axial direction AX1 may be smaller than the width of a side portion 1092 of the first positioning seat 109 on the first axial direction AX1, but is not limited thereto.

[0157] As Figure 4 shown in Figure 5 the figure, the first base 112 may further have a second receiving surface 1122, which is disposed in the first receiving space AS1, faces the first driving assembly DA1 and the first positioning seat 109, and the second receiving surface 1122 is not parallel to the first receiving surface 1121, for example, perpendicular to the first receiving surface 1121.

[0158] Similarly, the first base 112 may further have a third receiving surface 1123, which is disposed in the first receiving space AS1, faces the first driving assembly DA1 and the first positioning seat 109, and the third receiving surface 1123 is not parallel to the first receiving surface 1121 and the second receiving surface 1122. Among them, the third receiving surface 1123 may be perpendicular to the first receiving surface 1121 and the second receiving surface 1122, and the third receiving surface 1123 is connected to the second receiving surface 1122.

[0159] In this embodiment, the shortest distance between the first receiving surface 1121 and the first positioning seat 109 is different from the shortest distance between the second receiving surface 1122 and the first positioning seat 109. Specifically, the shortest distance between the first receiving surface 1121 and the first positioning seat 109 (for example, 0) is smaller than the shortest distance between the second receiving surface 1122 and the first positioning seat 109 (greater than 0).

[0160] That is, there is a first gap GP1 between the second receiving surface 1122 and the first positioning seat 109 to ensure that there is sufficient space to adjust the positions of the first driving assembly DA1 and the first positioning seat 109 in the first receiving space AS1.

[0161] Similarly, the shortest distance between the second receiving surface 1122 and the first positioning seat 109 is different from the shortest distance between the third receiving surface 1123 and the first positioning seat 109. Specifically, the shortest distance between the second receiving surface 1122 and the first positioning seat 109 is greater than the shortest distance between the third receiving surface 1123 and the first positioning seat 109.

[0162] Similarly, the shortest distance between the third receiving surface 1123 and the first positioning seat 109 is different from the shortest distance between the first receiving surface 1121 and the first positioning seat 109. Specifically, the shortest distance between the third receiving surface 1123 and the first positioning seat 109 (e.g., greater than 0) is greater than the shortest distance between the first receiving surface 1121 and the first positioning seat 109 (e.g., 0).

[0163] Furthermore, as Figures 3 to 5 shown, the first fixing surface 1124 faces the first positioning seat 109. Correspondingly, the first positioning seat 109 has a first positioning surface 1093 facing the first fixing surface 1124. It should be noted that since there is a gap between the third receiving surface 1123 and the first positioning seat 109, when adjusting the position of the first positioning seat 109 through the first connecting element 106, the first positioning seat 109 may be slightly tilted.

[0164] For example, as Figure 4 and Figure 5 shown, when the first positioning seat 109 is tilted, the first fixing surface 1124 is neither parallel nor perpendicular to the first positioning surface 1093. For example, the angle between the first positioning surface 1093 and the first fixing surface 1124 is, for example, less than 15 degrees. Additionally, the first axial direction AX1 can be perpendicular to the first fixing surface 1124.

[0165] Next, as Figure 5 shown, when viewed along the first axial direction AX1, a center line CNL1 of the first connecting element 106 does not overlap with a center line CNL2 of the first contact element 105. As Figure 5 shown, the first contact element 105 has a semi-circular structure, and the center line CNL2 passes through the vertex of the semi-circle.

[0166] Similarly, when viewed along the first axial direction AX1, the center line CNL1 of the first connecting element 106 does not overlap with the center line CNL3 of the first corresponding part 107. That is to say, the first connecting element 106 is offset from the center of the first corresponding part 107.

[0167] Specifically, when viewed along the main axis MX (Z-axis), the first corresponding part 107 has a first inner side surface 1071 and a second inner side surface 1072, and the first inner side surface 1071 faces the second inner side surface 1072. As Figure 5 shown, when viewed along the main axis MX, the first connecting element 106 contacts the first inner side surface 1071 without contacting the second inner side surface 1072.

[0168] In addition, it is worth noting that in this embodiment, the first optical module 100 may further have a first intermediate element CE1, which is disposed between the second corresponding part 111 and the first connecting element 106, and the first intermediate element CE1 is made of a non-metallic material. For example, the first intermediate element CE1 can be a non-slip cloth, silica gel, double-sided tape, rubber, etc.

[0169] Based on the configuration of the first intermediate element CE1, it is possible to avoid the problem that the first connecting element 106 gradually detaches from the first corresponding part 107 and the second corresponding part 111 due to vibration during the process of the first driving assembly DA1 driving the first rotating assembly 120 and the first movable part 108, ensuring the overall reliability.

[0170] Next, please refer to Figure 2 、 Figures 7 to 9 。 Figure 7 FIG. is an exploded view of a second optical module 200 according to an embodiment of the present disclosure, Figure 8 FIG. is a top view of a partial structure of the second optical module 200 according to an embodiment of the present disclosure, and Figure 9 FIG. is a sectional view of the optical element driving mechanism 10 along the Figure 1 line B-B in

[0171] Similar to the first optical module 100, the second optical module 200 may include the aforementioned second driving assembly DA2 and a second positioning seat 209, the second positioning seat 209 is fixedly disposed on the first movable part 108, and the second optical module 200 further includes a second connecting assembly LA2 configured to connect the second driving assembly DA2 and the second positioning seat 209 to the first movable part 108.

[0172] Specifically, as Figure 9As shown, the second connection assembly LA2 includes a third connection element 206 and a third corresponding part 207. The third connection element 206 contacts the second positioning seat 209, and the third corresponding part 207 has a groove structure and is configured to accommodate at least a part of the third connection element 206. Among them, the third corresponding part 207 is provided on the second positioning seat 209, but is not limited thereto. In other embodiments, the third corresponding part 207 may also be provided on the first movable part 108.

[0173] It should be noted that the extending direction of the third connection element 206 is parallel to the extending direction of the first connection element 106. Therefore, such a configuration can increase the convenience of installing the first optical module 100 and the second optical module 200.

[0174] The second connection assembly LA2 may further include a fourth corresponding part 108H, and the fourth corresponding part 108H has an opening structure and is configured to contact the third connection element 206. The fourth corresponding part 108H is, for example, a screw hole of the first movable part 108, but is not limited thereto.

[0175] Similar to the first optical module 100, the second optical module 200 may also have a second intermediate element CE2, which is disposed between the fourth corresponding part 108H and the third connection element 206 to prevent the third connection element 206 from detaching from the second positioning seat 209 and the first movable part 108. The material of the second intermediate element CE2 may be the same as or similar to that of the first intermediate element CE1, so it will not be elaborated here.

[0176] Furthermore, the second connection assembly LA2 may further include a fourth connection element 210, which extends along the first axial direction AX1, and the second positioning seat 209 correspondingly has a second positioning hole 2091, such that the fourth connection element 210 passes through the second positioning hole 2091 of the second positioning seat 209 and the second driving assembly DA2 to connect the second positioning seat 209 and the second driving assembly DA2 (in a screwed manner).

[0177] As Figure 7 and Figure 8 shown, the first movable part 108 may further have a second accommodation space AS2, which is configured to accommodate at least a part of the second positioning seat 209 and the second driving assembly DA2. The second accommodation space AS2 is, for example, a groove, but is not limited thereto. Similar to the first optical module 100, the size of the second accommodation space AS2 is larger than the sizes of the second positioning seat 209 and the second driving assembly DA2, such that the positions of the second positioning seat 209 and the second driving assembly DA2 in the second accommodation space AS2 can be adjusted through the third connection element 206.

[0178] Similarly, as Figure 8 and Figure 9As shown, the first movable part 108 may have a fourth receiving surface 1081 disposed in the second receiving space AS2 and configured to carry a part of the second positioning seat 209. When viewed along the main axis MX, the area of the fourth receiving surface 1081 may be larger than the area of the second positioning seat 209.

[0179] Furthermore, the first movable part 108 also has a fifth receiving surface 1082 disposed in the second receiving space AS2, facing the second positioning seat 209, and the fifth receiving surface 1082 is not parallel to the fourth receiving surface 1081. For example, the fifth receiving surface 1082 is perpendicular to the fourth receiving surface 1081.

[0180] Similarly, the first movable part 108 also has a sixth receiving surface 1083 disposed in the second receiving space AS2, facing the second positioning seat 209, and the sixth receiving surface 1083 is not parallel to the fourth receiving surface 1081 and the fifth receiving surface 1082. For example, the sixth receiving surface 1083 is perpendicular to the fourth receiving surface 1081 and the fifth receiving surface 1082.

[0181] It should be noted that as Figure 8 shown, when viewed along the main axis MX, the shortest distance between the fifth receiving surface 1082 and the second positioning seat 209 is greater than the shortest distance between the sixth receiving surface 1083 and the second positioning seat 209. Based on such a configuration, a second gap GP2 is provided between the fifth receiving surface 1082 and the second positioning seat 209 to ensure that the second positioning seat 209 can move in the second receiving space AS2.

[0182] Furthermore, the first movable part 108 may also have a seventh receiving surface 1084 facing the second positioning seat 209, and the second positioning seat 209 correspondingly has a second positioning surface 2093 facing the seventh receiving surface 1084. Since there may be a gap between the sixth receiving surface 1083 and the second positioning seat 209, when the second positioning seat 209 is driven by the third connecting element 206 to move along the first axial direction AX1, the seventh receiving surface 1084 may not be parallel to the second positioning surface 2093 nor perpendicular to the second positioning surface 2093.

[0183] Please continue to refer to Figure 7 and Figure 9 . 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 fixed shaft 230 and the second rotor 222, and these second balls 223 are located between the second stator 221 and the second rotor 222, so that the second rotor 222 can rotate relative to the second stator 221.

[0184] Similar to the first driving component DA1, the second driving component DA2 may include a second conduction component 204, a second contact 205, and a second power source 214. The second conduction component 204 is configured to generate a second driving force, and the second conduction component 204 may have an elastic structure that can flex to output the second driving force.

[0185] Specifically, the second power source 214 may be a second piezoelectric element configured to generate deformation to push the second conduction component 204, causing the second conduction component 204 to flex and output the second driving force.

[0186] Similarly, the second contact 205 is fixedly disposed on the second conduction component 204 and configured to conduct the second driving force. When the second conduction component 204 flexes, it can drive the second contact 205 to move along an elliptical trajectory (when viewed along the second axis AX2, as Figure 9 ), and then repeatedly contact and drive the second rotor 222 to rotate. The specific actuation method is the same as that of the first driving component DA1.

[0187] Furthermore, as Figure 7 and Figure 9 shown, the second movable part 208 is fixedly connected to the second rotor 222, and the second contact 205 pushes the second rotor 222 to rotate relative to the second stator 221 around the second rotation axis RX2 according to the second driving force, causing the second movable part 208 to drive the imaging module 150 to rotate around the second rotation axis RX2.

[0188] In this embodiment, as Figure 7 shown, the second movable part 208 may have a receiving part 2081 configured to receive a part of the second rotor 222. Correspondingly, the second optical module 200 may further have an adhesive element AD1 configured to be disposed between a contact inner surface 2082 of the receiving part 2081 and the second rotor 222.

[0189] In addition, the second movable part 208 may further have a side groove 2083 configured to receive a part of the adhesive element AD1. The side groove 2083 may have a setting surface 2084, and a part of the adhesive element AD1 is disposed on the setting surface 2084. Based on the configuration of the side groove 2083, the adhesive element AD1 can more stably fix the second rotor 222 to the second movable part 208.

[0190] It should be noted that, in this embodiment, the roughness of the contact inner surface 2082 is different from that of the setting surface 2084. Specifically, the roughness of the contact inner surface 2082 is greater than that of the setting surface 2084, so that a larger contact area between the contact inner surface 2082 and the bonding element AD1 can be obtained, and thus the second rotor 222 can be more firmly fixed to the accommodating portion 2081 without falling off.

[0191] Furthermore, in this embodiment, as Figure 7 shown, the second base 212 may have a first stop portion 2121 and a second stop portion 2122, and when the second movable portion 208 is driven to rotate around the second rotation axis RX2, the first stop portion 2121 and the second stop portion 2122 can be configured to stop the second movable portion 208 to limit the rotation angle range of the second movable portion 208. The first stop portion 2121 and the second stop portion 2122 are, for example, inclined surfaces and are not parallel to each other.

[0192] In addition, as Figure 9 shown, the second movable portion 208 may further have two chamfer structures 2085 located on the upper and lower sides of the accommodating portion 2081. Based on the configuration of the chamfer structures 2085, the second rotating assembly 220 can be more easily installed into the accommodating portion 2081. Moreover, since the ends of the chamfer structures 2085 have arc structures, the problem of damaging the second driving assembly DA2 when the chamfer structures 2085 touch the second driving assembly DA2 can also be avoided.

[0193] In summary, the present disclosure provides an optical element driving mechanism 10, including a first optical module 100, a second optical module 200, a first driving assembly DA1, and a second driving assembly DA2. The second movable portion 208 of the second optical module 200 is configured to carry a camera module 150, and the second optical module 200 is fixedly disposed on the first movable portion 108 of the first optical module 100. The first driving assembly DA1 is configured to drive the first movable portion 108 and the second optical module 200 to rotate around the first rotation axis RX1, and the second driving assembly DA2 is configured to drive the second movable portion 208 and the camera module 150 to rotate around the second rotation axis RX2 relative to the first movable portion 108 and the first base 112.

[0194] The first optical module 100 further includes a first connection element 106 and a second connection element 110. The first driving assembly DA1 is fixedly disposed on the first positioning seat 109 through the second connection element 110, and the first positioning seat 109 is connected to the first base 112 through the first connection element 106. The first connection element 106 can be a screw, and the first connection element 106 contacts the first positioning seat 109 without being locked to the first positioning seat 109. By adjusting the first connection element 106, the positions of the first positioning seat 109 and the first driving assembly DA1 in the first axial direction AX1 (Y-axis) can be adjusted to further adjust the pre-pressure applied by the first contact member 105 to the first rotating assembly 120, so as to ensure that the first contact member 105 can correctly drive the first rotating assembly 120.

[0195] Similar to the first optical module 100, the second optical module 200 further includes a third connection element 206 and a fourth connection element 210. The second driving assembly DA2 is fixedly disposed on the second positioning seat 209 through the fourth connection element 210, and the second positioning seat 209 is connected to the first movable part 108 through the third connection element 206. The third connection element 206 can be a screw, and the third connection element 206 contacts the second positioning seat 209 without being locked to the second positioning seat 209. By adjusting the third connection element 206, the positions of the second positioning seat 209 and the second driving assembly DA2 in the first axial direction AX1 (Y-axis) can be adjusted to further adjust the pre-pressure applied by the second contact member 205 to the second rotating assembly 220, so as to ensure that the second contact member 205 can correctly drive the second rotating assembly 220.
