Description

Technical Field

[0001] The present invention relates to an optical element driving mechanism, and more particularly to a periscope optical element driving mechanism. Background Art

[0002] With the progress of technology, many current electronic devices (e.g., smartphones, tablets) are equipped with the functions of taking photos or videos. The demands for these electronic devices are increasing day by day, and they are developing towards thinner, lighter, and high-performance designs to provide users with more convenient and diverse options. Generally, electronic devices with photo-taking or video-recording functions include one or more lenses to achieve functions such as focusing, zooming, and / or optical image stabilization (OIS). Among them, the periscope lens, with its unique refraction structure, can provide a higher optical zoom ratio within a limited device thickness, and has become one of the important technologies for improving the image performance of electronic devices.

[0003] However, in the prior art, the combination of liquid optical elements and periscope lenses still faces technical challenges. Although liquid optical elements have the advantages of simple structure, small volume, and smooth zooming, their compensation angle range is limited, making it difficult to meet the angle offset requirements of periscope lenses under high-magnification zooming, thus affecting image stability and image quality. The present invention proposes an optical element driving mechanism aimed at solving the problem of insufficient compensation angle of liquid optical elements. Through specific designs and drive control mechanisms, not only is the compensation angle increased, but also the optical requirements of periscope lenses are adapted, enabling them to provide stable and clear images even in larger offset scenarios. Summary of the Invention

[0004] The object of the present invention is to propose an optical element driving mechanism to solve at least one of the above problems.

[0005] The present invention provides an optical element driving mechanism, which includes a movable part, a fixed part, and a driving component. The first movable part is used to connect the first optical element. The first movable part can move relative to the fixed part. The first driving component is used to drive the first movable part to move relative to the fixed part.

[0006] According to some embodiments of the present disclosure, the optical element driving mechanism further includes a second movable part and a second driving component. The second movable part is used to connect the second optical element, and the first movable part can move relative to the second movable part and can also move relative to the fixed part. The second driving component is used to drive the second movable part to move relative to the fixed part. The first driving component is used to drive the first movable part to rotate about the first rotation axis. The first movable part can rotate about the first rotation axis relative to the second movable part within a first movement range. The second driving component is used to drive the second movable part to rotate about the second rotation axis, and the first movable part can rotate about the second rotation axis relative to the fixed part within a second movement range. The first movement range is different from the second movement range, the second movement range is smaller than the first movement range, the first rotation axis is parallel to the second rotation axis, and the first rotation axis does not overlap the second rotation axis.

[0007] The beneficial effect of the present invention is that the optical element driving mechanism of the present disclosure includes two movable parts (the first movable part and the second movable part). Through a specific design and driving control mechanism, not only is the compensation angle increased, but also the optical element driving mechanism can still provide a stable and clear image in a larger offset scenario.

[0079] Figure 1 Shows a perspective view of the optical element driving mechanism 1000 according to some embodiments of the present disclosure. Figure 2 Shows an exploded view of the optical element driving mechanism 1000 according to some embodiments of the present disclosure. The overall structure of the optical element driving mechanism 1000 will be described in detail below. Please refer to Figure 1 and Figure 2 .

[0080] According to some embodiments of the present disclosure, the optical element driving mechanism 1000 includes a fixing part 1100, a first moving part 1200, a first optical element 1210, a first driving component 1300, a circuit component 1400, a second moving part 1500, a second optical element 1510, a second driving component 1600, a first supporting component 1700, a second supporting component 1800, and a control component 1900.

[0081] According to some embodiments of the present disclosure, the fixing part 1100 includes a housing 1110 and a base 1120. The housing 1110 is fixedly connected to the base 1120 to form an accommodation space for accommodating other elements of the optical element driving mechanism 1000.

[0082] According to some embodiments of the present disclosure, the first moving part 1200 can move relative to the fixing part 1100. The first moving part 1200 is used to connect the first optical element 1210. That is to say, the first moving part 1200 is a carrier for carrying the first optical element 1210.

[0083] In some embodiments, the first optical element 1210 is a prism that can change the optical path. For example, the first optical element 1210 can adjust the traveling direction of light from a first axis (parallel to the Y axis) to a second axis (parallel to the X axis), and the first axis (parallel to the Y axis) and the second axis (parallel to the X axis) are not parallel to each other.

[0084] According to some embodiments of the present disclosure, the first driving component 1300 is used to drive the first movable part 1200 to move. The first driving component 1300 includes a first magnetic element 1310, two second magnetic elements 1320, 1330, a first coil 1340, and two second coils 1350, 1360.

[0085] According to some embodiments of the present disclosure, the first magnetic element 1310 and the second magnetic elements 1320, 1330 are disposed at the bottom of the first movable part 1200. The first coil 1340 and the second coils 1350, 1360 are disposed on the circuit member 1400. The first magnetic element 1310 corresponds to the first coil 1340, and the second magnetic elements 1320, 1330 respectively correspond to the second coils 1350, 1360.

[0086] Specifically, when a driving signal is applied to the first coil 1340 (for example, current is applied through an external power source), an electromagnetic induction force is generated between the first magnetic element 1310 and the first coil 1340, thereby driving the first movable part 1200 to rotate about an axis parallel to the Z-axis to drive the first optical element 1210 to a desired position.

[0087] Similarly, when driving signals are respectively applied to the second coils 1350, 1360 (for example, current is applied through an external power source), electromagnetic induction forces are respectively generated between the second magnetic elements 1320, 1330 and the second coils 1350, 1360, thereby driving the first movable part 1200 to rotate about an axis parallel to the Y-axis to drive the first optical element 1210 to a desired position.

[0088] According to some embodiments of the present disclosure, the circuit member 1400 is fixedly connected to the base 1120. The circuit member 1400 includes a bottom surface 1410, a connecting portion 1420, and a pair of side portions 1430, 1440. The bottom surface 1410 is connected to the pair of side portions 1430, 1440 through the connecting portion 1420 respectively.

[0089] According to some embodiments of the present disclosure, the bottom surface 1410 is perpendicular to the connecting portion 1420 and the pair of side portions 1430, 1440. The connecting portion 1420 is perpendicular to the side portions 1430, 1440. The side portions 1430, 1440 are parallel to each other on opposite sides of the base 1120. The first coil 1340 and the second coils 1350, 1360 are disposed on the bottom surface 1410.

[0090] According to some embodiments of the present disclosure, the second movable part 1500 can move relative to the fixed part 1100, and the first movable part 1200 can move relative to the second movable part 1500. The second movable part 1500 is used to movably connect the second optical element 1510. In some embodiments of the present disclosure, the second optical element 1510 is a liquid lens.

[0091] The liquid lens adjusts the focal length by changing the curvature of the transparent liquid interface, and controls the shape of the liquid by using an electric field, a magnetic field or mechanical extrusion to achieve rapid zoom. In some embodiments of the present disclosure, the second optical element 1510 is fixed on the housing 1110 and includes a light-transmitting body with a non-infinite focal length. The second optical element 1510 controls the curvature of the liquid interface to adjust the focal length by the mechanical extrusion caused by the movement of the second movable part 1500.

[0093] According to some embodiments of the present disclosure, the third magnetic elements 1610, 1620 are respectively arranged on opposite sides of the second movable part 1500, and the fourth magnetic elements 1630, 1640 are also respectively arranged on opposite sides of the second movable part 1500. The third magnetic element 1610 and the fourth magnetic element 1630 are arranged on the same side of the second movable part 1500. The third magnetic element 1620 and the fourth magnetic element 1640 are arranged on the same side of the second movable part 1500.

[0095] When driving signals (for example, applying current through an external power supply) are respectively applied to the third coils 1650, 1660( Figure 5 ), the third magnetic elements 1610, 1620 and the third coils 1650, 1660( Figure 5An electromagnetic induction force is generated between them respectively, and then the second movable part 1500 can be driven to rotate around a direction parallel to the Y-axis, so as to change the curvature of the liquid interface of the second optical element 1510 to adjust the focal length.

[0096] Similarly, when drive signals (for example, applying currents through an external power supply) are respectively applied to the fourth coils 1670, 1680 ( Figure 5 ), an electromagnetic induction force is generated between the fourth magnetic elements 1630, 1640 and the fourth coils 1670, 1680 ( Figure 5 ), and then the second movable part 1500 can be driven to rotate around a direction parallel to the Z-axis, so as to change the curvature of the liquid interface of the second optical element 1510 to adjust the focal length.

[0098] According to some embodiments of the present disclosure, the first support assembly 1700 includes a first support element 1710, a first corresponding element 1720, and a pair of first flexible elements 1730. In some embodiments of the present disclosure, the first support element 1710 can be a ball made of ceramic material, and the first corresponding element 1720 can be a metal plate-like structure corresponding to the first support element 1710.

[0099] According to some embodiments of the present disclosure, the first support element 1710 can move relative to the first corresponding element 1720.

The first flexible element 1730 and the second flexible element 1830 are located on opposite sides of the first optical element 1210, and the first corresponding element 1720 is located between the first support element 1710 and the second support element 1810( Figure 6 ).

[0103] According to some embodiments of the present disclosure, the control component 1900 is used to control the first driving component 1300 and the second driving component 1600. The control component 1900 includes a group of first sensing components 1910, 1920, two groups of second sensing components 1930, 1940 and a control unit (not shown), wherein only one group of the second sensing components 1930, 1940 can be seen in the Figure 2 view, and the other group of the second sensing components 1930, 1940 is visible in Figure 5 .

[0106] Figure 3 FIG. 19 is a perspective view of the optical element driving mechanism 1000 according to some embodiments of the present disclosure, wherein the housing 1110 is not shown for illustrative purposes. Figure 4 FIG. 20 is a perspective view of the first movable part 1200, the first optical element 1210, the second movable part 1500, the second optical element 1510 and the first flexible element 1730 of the optical element driving mechanism 1000 according to some embodiments of the present disclosure.

[0107] Please refer to Figure 3 and Figure 4 . As shown in Figure 3 and Figure 4As shown, the first movable part 1200 includes four protrusions 1201 extending in the X direction. The second movable part 1500 includes a front side 1501, a rear side 1502, a pair of side parts 1503, an opening 1504, four grooves 1505, a pair of end parts 1506, and a pair of extension parts 1507.

[0108] As Figure 4 shown, the first movable part 1200 is surrounded by the front side 1501, the rear side 1502, and the side parts 1503 of the second movable part 1500. As Figure 3 shown, the opening 1504 is located at the front side 1501. The light entering the optical element driving mechanism 1000 will enter the first optical element 1210 along the -Y direction, and leave the first optical element 1210 along the -X direction, and then enter the second optical element 1510 from the opening 1504 ( Figure 4 ).

[0109] As Figure 4 shown, two of the grooves 1505 are located on the side parts 1503. Although the other two grooves cannot be seen from Figure 4 here, it should be understood that the other two grooves 1505 on the other side are also located on the side parts 1503 on the other side in the same way. The four grooves 1505 are respectively used to accommodate Figure 2 the third magnetic elements 1610, 1620 and the fourth magnetic elements 1630, 1640 shown.

[0111] As Figure 4 shown, the extension part 1507 of the second movable part 1500 extends from the end part 1506 through the space between the protrusions 1201 of the two first movable parts 1200 to the rear side 1502.

[0113] As Figure 5 shown, the base 1120 includes a pair of opposite side surfaces 1121, 1122, a bottom surface 1123, a back surface 1124, and three openings 1125, 1126, 1127. The side surfaces 1121, 1122 and the back surface 1124 are perpendicular to the bottom surface 1123. The side surfaces 1121, 1122 are adjacent to the back surface 1124 respectively and perpendicular to the back surface 1124.

[0114] As Figure 5 shown, the opening 1125 is located in the side surface 1121, the opening 1126 is located in the side surface 1122, and the opening 1127 is located in the bottom surface 1123. The first coil 1340 and the second coils 1350, 1360 disposed on the circuit member 1400 are located in the space formed by the opening 1127.

[0115] Similarly, the third coil 1650 and the fourth coil 1670 disposed on the circuit member 1400 are located in the space formed by the opening 1125. The third coil 1660 and the fourth coil 1680 disposed on the circuit member 1400 are located in the space formed by the opening 1126.

[0116] As Figure 5 shown, the first sensing components 1910, 1920 are respectively located in the spaces formed by the annular structures of the first coil 1340 and the second coil 1360. Two second sensing components 1930 are respectively located in the spaces formed by the annular structures of the third coils 1650, 1660. Two second sensing components 1940 are respectively located in the spaces formed by the annular structures of the fourth coils 1670, 1680.

[0117] According to some embodiments of the present disclosure, the first sensing component 1910 is used to sense the movement of the first moving part 1200 around the Z axis. The first sensing component 1920 is used to sense the movement of the first moving part 1200 around the Y axis. The second sensing component 1930 is used to sense the movement of the second moving part 1500 around the Y axis. The second sensing component 1940 is used to sense the movement of the second moving part 1500 around the Z axis.

[0118] Figure 6 Showing the optical element driving mechanism 1000 according to some embodiments of the present disclosure along Figure 1A top view sectional view taken along the sectional line A-A. The first support element 1710 provided in the first movable part 1200 corresponds to the first corresponding element 1720 embedded in the second movable part 1500. The second support element 1810 provided in the second movable part 1500 corresponds to the second corresponding element 1820 embedded in the base 1120.

[0119] It should be understood that, in some embodiments, the first driving assembly 1300 ( Figure 2 ) is used to drive the first movable part 1200 to rotate with the first support element 1710 as a fulcrum and with a first rotation axis R1 (parallel to the Y axis) as the axis. The second driving assembly 1600 is used to drive the second movable part 1500 to rotate with the second support element 1810 as a fulcrum and with a second rotation axis R2 (parallel to the Y axis) as the axis.

[0120] The first movable part 1200 can rotate relative to the second movable part 1500 within a first movement range with the first rotation axis R1. It should be understood that, since when the second movable part 1500 moves, it will drive the first movable part 1200 to move relative to the fixed part 1100 ( Figure 2 ), therefore, the first movable part 1200 can also rotate relative to the fixed part 1100 ( Figure 2 ) within a second movement range with the second rotation axis R2. It should be understood that the first movement range is different from the second movement range. The second movement range is smaller than the first movement range. The first rotation axis R1 is parallel to the second rotation axis R2, and the first rotation axis R1 does not overlap the second rotation axis R2.

[0121] Similarly, the first driving assembly 1300 is used to drive the first movable part 1200 to rotate with the first support element 1710 as a fulcrum and with a third rotation axis (parallel to the Z axis) as the axis. The second driving assembly 1600 is used to drive the second movable part 1500 to rotate with the second support element 1810 as a fulcrum and with a fourth rotation axis (parallel to the Z axis) as the axis.

[0122] The first movable part 1200 can rotate relative to the second movable part 1500 within a third movement range with the third rotation axis. It should be understood that, since when the second movable part 1500 moves, it will drive the first movable part 1200 to move relative to the fixed part 1100 ( Figure 2 ), therefore, the first movable part 1200 can also rotate relative to the fixed part 1100 ( Figure 2 ) within a fourth movement range with the fourth rotation axis. It should be understood that the third movement range is different from the fourth movement range. The fourth movement range is smaller than the third movement range. The third rotation axis is parallel to the fourth rotation axis, and the third rotation axis does not overlap the fourth rotation axis.

[0123] Figure 7A block diagram showing preset information 1901 of a control component 1900 of an optical element driving mechanism 1000 according to some embodiments of the present disclosure. As Figure 7 shown, the control component 1900 includes the preset information 1901. The preset information 1901 includes a first mode 1901-1, a second mode 1901-2, and a third mode 1901-3. Please refer to the following in combination with Figure 6 and Figure 7 .

[0124] According to some embodiments of the present disclosure, in the first mode 1901-1, the purpose of driving is for a small-angle movement (e.g., when the optical element driving mechanism 1000 requires a small-angle correction). In the second mode 1901-2, the purpose of driving is for a large-angle movement (e.g., when the optical element driving mechanism 1000 requires a large-angle correction). In the third mode 1901-3, the purpose of driving is to make the optical axis move parallel.

[0125] According to some embodiments of the present disclosure, in the first mode 1901-1, the second movable part 1500 will be fixed at a preset position, and the control component 1900 will control the movement of the first movable part 1200 according to a first instruction. That is, in the first mode 1901-1, only the first movable part 1200 is driven for optical compensation.

[0126] According to some embodiments of the present disclosure, in the second mode 1901-2, the control component 1900 will control the second driving component 1600 ( Figure 2 ) to drive the second movable part 1500 to move according to a second instruction, and the control component 1900 will control the first driving component to drive the first movable part 1200 to move according to the first instruction.

[0127] In the second mode 1901-2, the movement directions of the first movable part 1200 and the second movable part 1500 are the same (e.g., the first movable part 1200 and the second movable part 1500 respectively use the first support element 1710 and the second support element 1810 as fulcrums and also move Figure 6 clockwise, counterclockwise, etc. in

[0128] According to some embodiments of the present disclosure, in the third mode 1901-3, the control component 1900 controls the second driving component to drive the second movable part 1500 to move according to the second instruction, and controls the first driving component to drive the first movable part 1200 to move according to the first instruction.

[0129] In the third mode 1901-3, the movement directions of the first movable part 1200 and the second movable part 1500 are opposite (for example, the first movable part 1200 and the second movable part 1500 rotate clockwise and counterclockwise respectively with the first support element 1710 and the second support element 1810 as the fulcrums, etc.).

[0130] According to some embodiments of the present disclosure, a control unit (not shown) selects to drive the first drive component 1300 ( Figure 2 ) and the second drive component 1600 ( Figure 2 ) in the first mode 1901-1, the second mode 1901-2 or the third mode 1901-3 according to a main instruction (provided by a central component such as a mobile phone, a tablet, etc.), preset information 1901, a first sensing signal, and a second sensing signal.

[0131] As Figure 7 shown, the preset information 1901 further includes a first database 1901-4 and a second database 1901-5. The first database 1901-4 includes a first piece of information 1901-41, a second piece of information 1901-42, and a third piece of information 1901-43.

[0132] It should be understood that since the movement of the second movable part 1500 will drive the movement of the first movable part 1200, it is necessary to correct and record the sensing signals to distinguish the sensing signals output by the first movable part 1200 and the second movable part 1500 at different positions and their actual positions.

[0133] First, it is necessary to observe the movement mode of the second movable part 1500 and its influence on the first movable part 1200, and collect relevant data as the analysis basis. The movement range of the second movable part 1500 can be recorded by recording multiple node data within the movement range, and the stroke of the first movable part 1200 can be measured for each node. Subsequently, the stroke data of the first movable part 1200 and the second movable part 1500 are integrated to generate a data set describing the total stroke change of the two for further analysis.

[0134] During the measurement process, first measure the movement range of the second movable part 1500, select multiple representative points as references, and record the corresponding data. Next, according to the data results of the movement of the second movable part 1500, adjust the position of the first movable part 1200 and measure its stroke at each point to ensure the integrity and accuracy of data collection.

[0135] For different optical compensation requirements, the motion strategy will be different. When the optical compensation requirement is small, the first movable part 1200 is preferentially driven to move, while the second movable part 1500 remains stationary; when the optical compensation requirement is large, the second movable part 1500 is first driven to complete the corresponding movement, and then the first movable part 1200 is driven.

[0136] It should be noted that when the second movable part 1500 moves, the first database 1901-4 and the second database 1901-5 must be obtained to get the motion state of the first movable part 1200, so as to ensure the coordination and accuracy of the movements of the two. The data content of the first database 1901-4 and the second database 1901-5 will be described below.

[0137] According to some embodiments of the present disclosure, the first information 1901-41 includes the comparison information between the first sensing signal and the motion condition of the first movable part 1200 when the second movable part 1500 is in a first preset state (for example, Figure 6 the preset position).

[0138] According to some embodiments of the present disclosure, the second information 1901-42 includes the comparison information between the first sensing signal and the motion condition of the first movable part 1200 when the second movable part 1500 is in a second preset state (for example, an extreme position).

[0139] According to some embodiments of the present disclosure, the third information 1901-43 includes the comparison information between the first sensing signal and the motion condition of the first movable part 1200 when the second movable part 1500 is in a third preset state (for example, another extreme position relative to the second preset state). The first preset state, the second preset state, and the third preset state are different from each other.

[0140] According to some embodiments of the present disclosure, the second database 1901-5 includes a fourth information 1901-51, and the fourth information 1901-51 is the comparison information between the second sensing signal and the motion condition of the second movable part 1500. It should be understood that the control unit outputs a first instruction according to the main instruction, the first sensing signal, the second sensing signal, and the preset information 1901. The control unit outputs a second instruction according to the main instruction, the second sensing signal, and the preset information. The control unit does not output a second instruction according to the first sensing signal.

[0141] In summary, the optical element driving mechanism of the present disclosure includes two movable parts (the first movable part and the second movable part). Through a specific design and driving control mechanism, not only the compensation angle is increased, but also the optical element driving mechanism can still provide a stable and clear image in a larger offset situation.

[0142] In addition, the present disclosure also features the coordinated movement of two movable parts achieved through precise data collection. In particular, the reference to the database during the movement ensures the precise coordination and synchronous movement of the two movable parts, enabling the increased compensation angle to be effectively applied even in a larger offset scenario, further enhancing the stability and operating efficiency of the system.
