[0119] Many different arrangements will be permissible in light of the above detailed description of the application. Indeed, those skilled in the art, having the benefit of the present disclosure, will appreciate that modifications can be made by persons skilled in the art without departing from the scope of the application. Accordingly, no limitation is placed on the scope of the application by the specific arrangements set forth in the description below. For example, while the specification has discussed forming a first feature on top of a second feature, this can include embodiments where the first feature is in direct contact with the second feature, and can also include embodiments where additional features are formed between the first and second features, such that the first and second features can not be in direct contact.

[0120] In addition, use of repetitive description of features can be repeated in different instances in the description. This repetition is for the sake of simplicity and clarity and is not intended to convey that one different instance is a required substitute for another different instance or that one different instance is preferred over another different instance. In addition, forming a feature on top of, connecting to, and / or coupling to another feature in the description can include embodiments where the features are formed in direct contact, and can also include embodiments where additional features can be formed interposed between the features, such that the features can not be in direct contact. In addition, where spatially relative terms are used, such as "beneath", "below", "lower", "above", "upper", "vertical", "horizontal", and the like, it is understood that these spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the position of one element relative to another element as depicted in the figures. For example, if a device described herein is turned over, then a relative term such as "below" or "beneath" can then be interpreted as "above" or "over" relative to the other element or features.

[0121] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0122] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify the elements of the claims does not imply or represent any prior ordinal number of the claimed element, nor does it represent the order of one claimed element with another, or the order of manufacturing methods. The use of multiple ordinal numbers is only to enable a claimed element with a certain name to be clearly distinguished from another claimed element with the same name.

[0123] Furthermore, in some embodiments of this utility model, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or they may refer to two structures not in direct contact, with other structures disposed between them. Moreover, these terms regarding joining and connecting may also include cases where both structures are movable or both structures are fixed.

FIG. 2D This is a top view of the first intermediate element 1410A, the first movable part 1210A, and the second movable part 1220A. (See attached image.) FIG. 2A to FIG. 2D As shown, when viewed along the main axis 1900A, the main body 1411A may have an L-shaped shape, for example, it may be provided on two sides of the first movable part 1210A or the second movable part 1220A.

[0137] In some embodiments, the contact unit 1412A may have a spherical or hemispherical arc shape, and may be located on the body 1411A to reduce the contact area between the first intermediate element 1410A and the first movable part 1210A and the second movable part 1220A, thereby reducing the friction between the first intermediate element 1410A and the first movable part 1210A and the second movable part 1220A, so as to allow the first intermediate element 1410A to movably connect the first movable part 1210A and the second movable part 1220A.

[0138] In some embodiments, the first intermediate element 1410A can be used to guide the first movable portion 1210A to move relative to the second movable portion 1220A in a specific direction. For example, such as FIG. 2B As shown, the first recessed structure 1211A of the first movable portion 1210A may have a groove structure extending in the X direction, and the contact unit 1412A may be partially disposed in the first recessed structure 1211A, thereby allowing the first intermediate element 1410A to move in the X direction relative to the first movable portion 1210A. Furthermore, as... FIG. 2C As shown, the second recessed structure 1221A of the second movable part 1220A may have a groove structure extending in the Y direction, and the contact unit 1412A may be partially disposed in the second recessed structure 1221A, thereby allowing the first intermediate element 1410A to move in the Y direction relative to the second movable part 1220A.

[0139] like FIG. 2DAs shown, the contact unit 1412A can at least partially overlap with the first recessed structure 1211A and the second recessed structure 1221A when viewed along the main axis 1900A, for example, a portion of the contact unit 1412A can be disposed in the first recessed structure 1211A, and another portion of the contact unit 1412A can be disposed in the second recessed structure 1221A. In addition, the surface of the contact unit 1412A can have a spherical or arc surface structure to reduce the friction when in contact with the first recessed structure 1211A and the second recessed structure 1221A. That is, the first movable part 1210A can be moved in the XY plane relative to the second movable part 1220A by the first intermediate element 1410A to achieve the optical anti-shake function. In addition, since the first intermediate element 1410A can be disposed in the XY plane, the size of the optical element driving mechanism 1000A in the Z axis can be reduced to achieve miniaturization.

[0140] It should be noted that since the aforementioned contact unit 1412A is clamped by the first movable part 1210A and the second movable part 1220A, the movable directions of the first intermediate element 1410A, the first movable part 1210A and the second movable part 1220A are limited, so that when the first movable part 1210A moves relative to the second movable part 1220A, they do not flip or rotate relative to each other, thereby reducing the difficulty of driving and improving the accuracy of driving.

[0141] FIG. 3A is a top view of some elements of the optical element driving mechanism 1000A, FIG. 3B is a side view of some elements of the optical element driving mechanism 1000A, mainly showing elements near the coil assembly 1320A and the first circuit element 1511A. As FIG. 3A 、 FIG. 3B As shown, the first circuit element 1511A can have a first surface 1513A, and the first surface 1513A can have a first soldering portion 1931A and a second soldering portion 1932A. The first soldering portion 1931A can correspond to the first coil 1321A, and the second soldering portion 1932A can correspond to the first electronic element 1541A. In some embodiments, the first coil 1321A can be electrically connected to the first soldering portion 1931A via a first electrical connection element 1543A, and the first electronic element 1541A can be electrically connected to the second soldering portion 1932A via a second electrical connection element 1544A. In some embodiments, the first electrical connection element 1543A and the second electrical connection element 1544A can include conductive materials, such as conductive glue, solder, etc. The second electronic element 1542A can be disposed in the second coil 1322A, and its configuration can be similar to that of the first electronic element 1541A and the first coil 1321A described later.

[0142] In some embodiments, the aforementioned first electronic component 1541A and second electronic component 1542A may include a Hall sensor, a magnetoresistance effect sensor (MRSensor), a giant magnetoresistance effect sensor (GMR Sensor), a tunneling magnetoresistance effect sensor (TMR Sensor), or a fluxgate sensor.

[0143] In some embodiments, such as FIG. 3A As shown, when viewed along a direction perpendicular to the first surface 1513A (e.g., the Z direction), the area of ​​the first weld portion 1931A can be larger than the area of ​​the second weld portion 1932A. Furthermore, as... FIG. 3B As shown, in a direction perpendicular to the first surface 1513A (e.g., the X direction), the maximum size 1924A of the first electrical connection element 1543A may differ from the maximum size 1925A of the second electrical connection element 1544A, for example, it may be larger than the maximum size 1925A of the second electrical connection element 1544A. In some embodiments, a first bonding element 1545A may be provided between the first circuit element 1511A and the first coil 1321A to fix the relative positions of the first circuit element 1511A and the first coil 1321A. In some embodiments, the first bonding element 1545A may directly contact the first electrical connection element 1543A and the second electrical connection element 1544A. The first bonding element 1545A may include a non-conductive bonding material.

[0144] In some embodiments, such as FIG. 3A As shown, the first coil 1321A may include a first receiving space 1911A, a second receiving space 1912A, and a connecting space 1913A. The first receiving space 1911A can be connected to the second receiving space 1912A via the connecting space 1913A. In some embodiments, a first electronic component 1541A may be disposed in the first receiving space 1911A. Furthermore, when viewed along the direction (Z direction) of the winding axis 1903A of the first coil 1321A, the area of ​​the first receiving space 1911A is different from the area of ​​the second receiving space 1912A. For example, the area of ​​the first receiving space 1911A may be larger than the area of ​​the second receiving space 1912A to allow the first electronic component 1541A to be disposed in a larger space.

[0145] In some embodiments, the first axis 1901A and the second axis 1902A can be perpendicular to the bobbin center 1903A, and the first axis 1901A and the second axis 1902A can be perpendicular to each other. The first accommodating space 1911A, the connecting space 1913A, and the second accommodating space 1912A can be arranged in sequence along the first axis 1901A, for example, along the X direction, and in the extension direction of the second axis 1902A (Y direction), the minimum size 1921A of the first accommodating space 1911A and the minimum size 1922A of the second accommodating space 1912A can be greater than the minimum size 1923A of the connecting space 1913A. In this way, the space occupied by the connecting space 1913A can be reduced, so that the first coil 1321A has a dumbbell-shaped structure, and the overall structure is miniaturized. The second coil 1322A can also have a structure similar to the first coil 1321A, which will not be described here.

[0146] FIG. 3C is a schematic view of some elements of the optical element driving mechanism 1000A. As shown in FIG. 3C the base 1120A can have a first circuit unit 1521A, a second circuit unit 1522A, and a third circuit unit 1523A. The first circuit unit 1521A can be connected to the first circuit element 1511A, the second circuit unit 1522A can be connected to the first circuit unit 1521A, and the third circuit unit 1523A can be connected to the second circuit unit 1522A. In this way, the electrical signal of the first circuit element 1511A can pass through the first circuit unit 1521A, the second circuit unit 1522A, and the third circuit unit 1523A in sequence to communicate with other devices outside. In some embodiments, the base 1120A can include a non-conductive material, and the first circuit unit 1521A, the second circuit unit 1522A, and the third circuit unit 1523A can include a conductive material, for example, can include metal.

[0147] In some embodiments, the first circuit unit 1521A can be partially embedded in the second movable part 1220A and partially exposed to the second movable part 1220A. The second circuit unit 1522A is arranged between the outer frame 1110A and the base 1120A, and can be exposed to the base 1120A and the second movable part 1220A to correspond to the second optical element (not shown in the present embodiment, for example, can correspond to the second optical element 1620B, 1620C, 1620D, 1620E of subsequent other embodiments).

[0148] In some embodiments, the second circuit unit 1522A can be disposed between the cover 1130A and the outer frame 1110A in the direction in which the main shaft 1900A extends. The third circuit unit 1523A can be partially embedded in the base 1120A and partially exposed from the base 1120A. That is, the first circuit unit 1521A can move relative to the third circuit unit 1523A.

[0149] In some embodiments, as shown in FIG. 1 1 A, the base 1120A can include a base upper surface 1121 A and a base lower surface 1122A, respectively facing opposite directions and perpendicular to the Z-axis. The third circuit unit 1523A can be partially exposed from the base upper surface 1121 A and the base lower surface 1122A. FIG. 3C

[0150] FIG. 1F FIG. 3C As shown in FIG. 1 1 A, the second intermediate element 1420A and the third intermediate element 1430A can have a long strip shape extending parallel to the main shaft 1900A and can be disposed between the second movable portion 1220A and the fixed portion 1100A, for example, between the second movable portion 1220A and the base 1120A, to movably connect the fixed portion 1100A and the second movable portion 1220A to allow the second movable portion 1220A to move relative to the fixed portion 1100A on the Z-axis, thereby achieving the auto-focusing function.

[0151] For example, the second intermediate element 1420A and the third intermediate element 1430A can be disposed on the second movable portion 1220A by frictional contact and fixed on the fixed portion 1100A (e.g., the base 1120A). In some embodiments, the second intermediate element 1420A and the third intermediate element 1430A can also be fixed on the second movable portion 1220A and disposed on the fixed portion 1100A (e.g., the base 1120A) by frictional contact, depending on design requirements.

[0152] ​​​It should be noted that, when the first optical element 1610A of this invention is in motion, if it needs to move in the XY plane, it can be movably connected to the first movable part 1210A and the second movable part 1220A through the first intermediate element 1410A, thereby allowing the first optical element 1610A to move in the XY plane relative to the fixed part 1100A along with the first movable part 1210A and the second movable part 1220A, to achieve the function of optical image stabilization. When the first optical element 1610A needs to move along the Z direction, it can be movably connected to the second movable part 1220A and the fixed part 1100A through the second intermediate element 1420A and the third intermediate element 1430A, thereby allowing the optical element to move in the Z-axis relative to the fixed part 1100A along with the first movable part 1210A and the second movable part 1220A, to achieve the function of autofocus. By using two different mechanisms to achieve optical image stabilization and autofocus separately, it is ensured that optical image stabilization and autofocus do not interfere with each other, thereby improving the accuracy of driving and sensing.

[0153] Although the foregoing embodiment connects the second optical element to the outside via a first circuit unit 1521A embedded in the second movable part 1220A, a second circuit unit 1522A exposed in the base 1120A and the second movable part 1220A, and a third circuit unit 1523A embedded in the base 1120A, the present invention is not limited thereto.

In some embodiments, the second optical element 1620B may include, for example, an aperture, shutter, or other optical element, and may be electrically connected to the first circuit unit 1521B. The first circuit unit 1521B is then electrically connected to the second circuit element 1512B, so that the second optical element 1620B can be electrically connected to an external device through the first circuit unit 1521B and the second circuit element 1512B. In some embodiments, the second circuit element 1512B may be fixed to the base 1120B. In some embodiments, the first circuit unit 1521B and the second circuit element 1512B may include, for example, a printed circuit board (PCB) or a flexible circuit board (FPC).

[0157] In some embodiments, such as FIG. 4F As shown, the base 1120B may include an adjacent upper base surface 1121B, a first base side surface 1123B, and a second base side surface 1124B, which are perpendicular to the Z-axis, X-axis, and Y-axis, respectively, meaning their normal vectors are parallel to the Z-axis, X-axis, and Y-axis, respectively.
