Description

Technical Field

[0001] This disclosure relates to an optical system. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0003] The aforementioned electronic devices with photographic or video recording functions typically include an optical system to drive optical elements (such as a lens) along the optical axis, thereby achieving autofocus (AF) or optical image stabilization (OIS). Light can pass through these optical elements and form an image on a photosensitive element. However, the current trend in mobile devices is towards smaller size and higher durability; therefore, effectively reducing the size of the optical system and improving its durability has become an important issue.

[0084] The following discloses many different implementations or examples to implement different features of the provided object. Specific embodiments of the elements and their arrangements are described below to illustrate this disclosure. Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of this disclosure. For example, the specification mentions that a first feature is formed on a second feature. This may include embodiments where the first and second feature are in direct contact, or embodiments where there are other features between the first and second feature; in other words, the first and second feature are not in direct contact.

[0085] Furthermore, repeated reference numerals or designations may be used in different embodiments. These repetitions are merely for the purpose of clearly and simply describing this disclosure and do not represent a specific relationship between the different embodiments and / or structures discussed. Additionally, the formation, connection, and / or coupling to another feature component in this disclosure may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed to insert into the aforementioned feature component, such that the aforementioned feature components may not be in direct contact. Furthermore, spatially related terms such as “vertical,” “above,” “up,” “below,” “bottom,” and similar terms (e.g., “downward,” “upward,” etc.) may be used to facilitate the description of the relationship between one element(s) or feature(s) in the illustrations and another element(s) or feature(s). These spatially related terms are intended to cover different orientations of the device including the feature.

[0086] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0087] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify elements of the claims does not imply or represent any prior ordinal number for the claimed element, nor does it represent the order of one claimed element with another, or the order of manufacturing methods. The use of such 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.

[0088] Furthermore, in some embodiments of this disclosure, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or to two structures not in direct contact, wherein another structure is disposed between the two structures. Moreover, these terms regarding joining and connection may also include cases where both structures are movable or both structures are fixed.

[0089] This disclosure provides an optical system for carrying optical elements. For example, Figure 1 This is a schematic diagram of an optical system 1000 according to some embodiments of the present disclosure. Figure 2 This is an exploded view of the optical system 1000. Figure 3A This is a top view of some components of the optical system 1000. Figure 3B It is along Figure 3A The cross-sectional view shown by the center line segment AA. Figure 3C This is a side view of some components of the optical system 1000. Figure 3D This is a bottom view of some components of the optical system 1000, in which components other than the outer frame 1100, base 1200, and circuit assembly 1700 are omitted for simplicity.

[0090] like Figures 1 to 3D As shown, the optical system 1000 mainly includes an outer frame 1100, a base 1200, a movable part 1300, a first driving element 1410, a second driving element 1420, a first elastic element 1510, a second elastic element 1520, a frame 1600, a circuit assembly 1700, a first electronic component 1802, and a second electronic component 1804. The movable part 1300 and the frame 1600 can be arranged along a first main axis 1901, while the outer frame 1100 and the base 1200 can be arranged along a second main axis 1902.

[0091] In some embodiments, the outer frame 1100, base 1200, and frame 1600 can be collectively referred to as the fixing part 1001, the first driving element 1410 and the second driving element 1420 can be collectively referred to as the driving assembly 1400, and the first elastic element 1510 and the second elastic element 1520 can be collectively referred to as the elastic assembly 1500. The movable part 1300 can be disposed in the fixing part 1001 to support an optical element (not shown). The movable part 1300 can move relative to the fixing part 1001 together with the optical element to achieve the functions of optical image stabilization (OIS) or autofocus (AF).

[0092] The aforementioned optical elements may include, for example, lenses, mirrors, prisms, beamsplitters, apertures, liquid lenses, image sensors, camera modules, and ranging modules. It should be noted that the definition of optical elements here is not limited to elements related to visible light; elements related to invisible light (e.g., infrared light, ultraviolet light) may also be included in this disclosure.

[0093] In some embodiments, a drive assembly 1400 is disposed on the movable portion 1300 and the fixed portion 1001 to drive the movable portion 1300 to move relative to the fixed portion 1001. For example, the first drive element 1410 may be a coil, and the second drive element 1420 may be a magnet. The first drive element 1410 and the second drive element 1420 may be disposed on the movable portion 1300 and the fixed portion 1001 respectively, or their positions may be interchanged, depending on design requirements. In some embodiments, the movable portion 1300 may be elastically connected to the fixed portion 1001 and suspended within the fixed portion 1001 by a first elastic element 1510 and a second elastic element 1520 made of metal (e.g., connected to a base 1200 or a frame 1600). The first elastic element 1510 and the second elastic element 1520 may be disposed on both sides of the movable portion 1300, for example. When the first driving element 1410 is energized, an electromagnetic driving force can be generated between the first driving element 1410 and the second driving element 1420 to drive the movable part 1300 and the optical element to move relative to the fixed part 1001, so as to achieve the functions of optical image stabilization or autofocus. In some embodiments, the driving assembly 1400 may also include driving elements such as piezoelectric elements and shape memory alloys.

[0094] In some embodiments, the circuit assembly 1700 may be disposed in the base 1200, and the circuit assembly 1700 may be electrically connected to other electronic components disposed inside or outside the optical system 1000, such as the first driving element 1410, the first electronic component 1802, the second electronic component 1804, etc., thereby enabling functions such as autofocus or optical image stabilization. The first electronic component 1802 and the second electronic component 1804 may be position sensors, for example, disposed in the base 1200, for sensing the position of the movable part 1300 relative to the base 1200. For example, the first electronic component 1802 and the second electronic component 1804 may include a Hall effect sensor, a magnetoresistive effect sensor (MR sensor), a giant magnetoresistive effect sensor (GMR sensor), a tunneling magnetoresistive effect sensor (TMR sensor), or a fluxgate sensor. In some embodiments, the first electronic component 1802 and the second electronic component 1804 may also include a driver integrated circuit element.

[0095] In some embodiments, the outer frame 1100 may be referred to as a first component, while the base 1200 and the circuit assembly 1700 may be collectively referred to as a second component, the second component being fixedly connected to the first component. For example, Figure 4A This is a schematic diagram of the second component. Figure 4B This is the side view of the second component. Figure 5A , Figure 5B This is a magnified view of the second component from different directions. Figure 6 This is the perspective view of the second component. Figure 7A This is a top view of circuit assembly 1700. Figure 7B , Figure 7C These are side views of circuit assembly 1700 viewed from different directions. Figure 7D This is a magnified perspective view of the optical system 1000.

[0096] In some embodiments, the base 1200 may include a body 1210 and a wall 1220, the wall 1220 extending from the body 1210 in a second direction, and the circuit assembly 1700 disposed within the body 1210 and partially exposed therefrom. In some embodiments, the wall 1220 has a protrusion 1230 extending upward in a third direction, and when viewed from a first direction or a third direction, the protrusion 1230 protrudes from the outer frame 1100 (first assembly). Furthermore, the outer frame 1100 includes a recess 1110, and the protrusion 1230 may be disposed in the recess 1110 to control the position of the outer frame 1100 relative to the base 1200. When viewed from a first direction, the protrusion 1230 may not overlap with the first connection portion 1713.

[0097] In some embodiments, the circuit assembly 1700 may include a first circuit element 1710, a second circuit element 1720, and a third circuit element 1730. The base 1200 may include a non-metallic material, such as electrically insulating material. For example, the first circuit element 1710 may include a first body 1711, a first connecting portion 1713, a second connecting portion 1714, and a bending portion 1715. The first connecting portion 1713 can be connected to the first body 1711 via the bending portion 1715, and the second connecting portion 1714 can be connected to the first body 1711. The second circuit element 1720 may include a second body 1721, a second solder portion 1722, and a third solder portion 1723. The second solder portion 1722 and the third solder portion 1723 are connected to the second body 1721. The third circuit element 1730 may include a fourth solder portion 1731. The first electronic component 1802 and the second electronic component 1804 are electrically connected to the first body 1711 of the first circuit component 1710, and the first circuit component 1710 is electrically insulated from the second circuit component 1720, the third circuit component 1730, and the outer frame 1100 (first assembly), while the second circuit component 1720 and the third circuit component 1730 are electrically connected to the outer frame 1100.

[0098] In some embodiments, the first connecting portion 1713, the second connecting portion 1714, the second welding portion 1722, the third welding portion 1723, and the fourth welding portion 1731 may be exposed from the base 1200. For example, the first connecting portion 1713, the second welding portion 1722, the third welding portion 1723, and the fourth welding portion 1731 may be exposed from the body 1210, while the second connecting portion 1714 may be disposed on the wall 1220. When viewed from a fourth direction, the second connecting portion 1714 extends in the second direction, is exposed from the wall 1220, and overlaps with the wall 1220. When viewed from a first direction, the first connecting portion 1713 may be exposed from the outer frame 1100 (first component) to allow electrical connection to the outside circuitry.

[0099] In some embodiments, the outer frame 1100 (first component) may be made of a conductive material (e.g., metal) and may include a first weld portion 1105, such as the portion of the outer frame 1100 that contacts the second weld portion 1722, the third weld portion 1723, and the fourth weld portion 1731, and the side of the first weld portion 1105 facing the circuit assembly 1700 may be referred to as the first weld surface 1106. The first weld portion 1105 may be fixedly connected to the second weld portion 1722, the third weld portion 1723, and the fourth weld portion 1731 by welding (e.g., soldering, laser welding, etc.). For example, in some embodiments, the second weld portion 1722 may include a second weld surface 1740, and the first weld surface 1106 and the second weld surface 1740 may be perpendicular to each other. In some embodiments, welding can be performed on the first welding surface 1106 and the second welding surface 1740 (e.g., by setting solder balls or by applying a laser to the first welding surface 1106 and the second welding surface 1740) to fix the outer frame 1100 and the circuit assembly 1700.

[0100] In some embodiments, when viewed from a first direction (-Z direction) parallel to the normal vector of the first welding surface 1106, the second welding portion 1722 is not exposed from the outer frame 1100 (first component), but when viewed from a second direction (+Z direction) opposite to the first direction, the second welding portion 1722 overlaps with the outer frame 1100 (first component). This allows welding of the first welding portion 1105 and the second welding portion 1722.

[0101] In some embodiments, the second weld portion 1722 and the third weld portion 1723 are arranged in a third direction (X direction), while the second weld portion 1722 and the fourth weld portion 1731 are arranged in a fourth direction (Y direction). The first direction (-Z direction), the second direction (+Z direction), the third direction (X direction), and the fourth direction (Y direction) are different from each other. It should be noted that the second weld surface 1740 may have a serrated, wavy, or other shape, and may not be parallel or perpendicular to the third or fourth direction, so that compared with a plane, the second weld surface 1740 may have a larger area, thereby increasing the welding range and reducing assembly problems caused by the tolerances of each component.

[0102] In some embodiments, in the Z direction, the first body 1711 and the bottom surface 1201 of the base 1200 have a first distance 1811, the first connecting portion 1713 and the bottom surface 1201 have a second distance 1812, and the third welding portion 1723 and the bottom surface 1201 have a third distance 1813. In some embodiments, the first distance 1811, the second distance 1812, and the third distance 1813 may be different from each other. For example, the first distance 1811 may be smaller than the second distance 1812 and the third distance 1813, and the second distance 1812 may be smaller than the third distance 1813. In other words, in some embodiments, the first body 1711, the first connecting portion 1713, and the third welding portion 1723 may be located at different heights to further utilize the space of the optical system 1000.

[0103] In some embodiments, the bent portion 1715 may be spaced apart from the outer frame 1100 and embedded in the base 1200 to electrically insulate it from the outer frame 1100, thereby preventing short circuits. In some embodiments, the first connecting portion 1713 and the fourth welding portion 1731 are arranged in a third direction. In this third direction, there is a fourth distance 1814 between the first connecting portion 1713 and the fourth welding portion 1731, and a fifth distance 1815 between the second welding portion 1722 and the third welding portion 1723. The fourth distance 1814 and the fifth distance 1815 are different; for example, the fourth distance 1814 may be greater than the fifth distance 1815. Furthermore, in some embodiments, in the fourth direction, there is a sixth distance 1816 between the first connecting portion 1713 and the third welding portion 1723, and a seventh distance 1817 between the second welding portion 1722 and the fourth welding portion 1731. The sixth distance 1816 and the seventh distance 1817 may be different; for example, the sixth distance 1816 may be greater than the seventh distance 1817.

[0104] In some embodiments, when viewed from a first direction, the first circuit element 1710 may at least partially overlap with the first electronic element 1802 and the second electronic element 1804. When viewed from a third direction (X direction), the first connecting portion 1713 may at least partially overlap with the first electronic element 1802 and the second electronic element 1804, while the first electronic element 1802 and the second electronic element 1804 may not overlap, and the third soldering portion 1722 may not overlap with the first electronic element 1802 and the second electronic element 1804. In some embodiments, the first connecting portion 1713 and the second connecting portion 1714 may at least partially overlap, while the second connecting portion 1714 and the third soldering portion 1723 may not overlap. Furthermore, in some embodiments, when viewed from the fourth direction (Y direction), the first electronic component 1802 and the second electronic component 1804 may at least partially overlap, the first connecting portion 1713 may not overlap with the first electronic component 1802, the second electronic component 1804, and the second connecting portion 1714, and the second connecting portion 1714 may at least partially overlap with the third welding portion 1723. This allows for a reduction in the size of the optical system 1000 in a specific direction, achieving miniaturization.

[0105] In some embodiments, the housing 1100 and the circuit assembly 1700 may comprise different materials, such as different metallic materials. For example, the material of the first weld portion 1105 may be different from the materials of the second weld portion 1722, the third weld portion 1723, and the fourth weld portion 1731, while the materials of the second weld portion 1722, the third weld portion 1723, and the fourth weld portion 1731 may be the same as each other. In some embodiments, a first welding element (not shown) may be provided on the first weld portion 1105, covering the first weld surface 1106, and a second welding element (not shown) may be provided on the second weld portion 1722 (or the third weld portion 1723, the fourth weld portion 1731), covering the second weld surface 1740. In some embodiments, the first welding element and the second welding element may be, for example, a surface coating having a different material from the first welding portion 1105, the second welding portion 1722, the third welding portion 1723, and the fourth welding portion 1731, to change the surface properties of the first welding portion 1105, the second welding portion 1722, the third welding portion 1723, and the fourth welding portion 1731, thereby allowing welding, but are not limited thereto. In some embodiments, the first welding element and the second welding element may not be provided, depending on design requirements.

[0106] The foregoing embodiments disclose second weld portions 1722, third weld portions 1723, and fourth weld portions 1731 having second weld surfaces 1740 with serrated, wavy, or other shapes; however, this disclosure is not limited thereto. For example, Figure 8This is a schematic diagram of a circuit assembly 2700 according to some embodiments of the present disclosure. In some embodiments, the circuit assembly 2700 may include a first circuit element 2710, a second circuit element 2720, and a third circuit element 2730. For example, in some embodiments, the first circuit element 2710 may include a first body 2711, a first connecting portion 2713, a second connecting portion 2714, and a bending portion 2715. The first connecting portion 2713 can be connected to the first body 2711 through the bending portion 2715, and the second connecting portion 2714 can be connected to the first body 2711. The second circuit element 2720 may include a second body 2721, a second soldering portion 2722, and a third soldering portion 2723. The second soldering portion 2722 and the third soldering portion 2723 are connected to the second body 2721. The third circuit element 2730 may include a fourth soldering portion 2731. The first electronic component 1802 and the second electronic component 1804 are electrically connected to the first body 2711 of the first circuit component 2710, and the first circuit component 2710 is electrically insulated from the second circuit component 2720, the third circuit component 2730, and the outer frame 1100 (first assembly), while the second circuit component 2720 and the third circuit component 2730 are electrically connected to the outer frame 1100.

[0107] In some embodiments, the first connecting portion 2713, the second connecting portion 2714, the second welding portion 2722, the third welding portion 2723, and the fourth welding portion 2731 may be exposed from the base 1200. For example, the first connecting portion 2713, the second welding portion 2722, the third welding portion 2723, and the fourth welding portion 2731 may be exposed from the body 1210, while the second connecting portion 2714 may be disposed on the wall 1220. When viewed from a fourth direction, the second connecting portion 2714 extends in the second direction, is exposed from the wall 1220, and overlaps with the wall 1220. When viewed from a first direction, the first connecting portion 2713 may be exposed from the outer frame 1100 (first component) to allow electrical connection to the outside circuitry.

[0108] In some embodiments, circuit assembly 2700 can be used to replace the aforementioned circuit assembly 1700, the main difference being that the shapes of the second solder portion 2722, the third solder portion 2723, and the fourth solder portion 2731 may differ from those of the aforementioned second solder portion 1722, the third solder portion 1723, and the fourth solder portion 1731. For example, the base 1200 and circuit assembly 2700 can also be collectively referred to as the second assembly. Figure 9A This is a schematic diagram of the second component. Figure 9B This is the bottom view of the second component. Figure 10A , Figure 10BThis is an enlarged view of the second component viewed from different directions. In some embodiments, the second welded portion 2722 (or the third welded portion 2723, the fourth welded portion 2731) may include a first portion 2741, a second portion 2742, a third portion 2743, and a heat insulation structure 2744. The first portion 2741 is connected to the third portion 2743 through the second portion 2742, and the heat insulation structure 2744 and the second portion 2742 are arranged in a fourth direction. In some embodiments, when viewed from a second direction, the first portion 2741 is exposed above the base 1200, a portion of the second portion 2742 is exposed above the base 1200, while another portion of the second portion 2742 is embedded in the base 1200, and the third portion 2743 is embedded in the base 1200.

[0109] The thermal insulation structure 2744 may be, for example, a hole. Therefore, when viewed from the second direction, the first welded surface 1106 may be exposed from the thermal insulation structure 2744. In the fourth direction, the second portion 2742 has a first width 2801, and the thermal insulation structure 2744 has a second width 2802. The first width 2801 may differ from the second width 2802; for example, the first width 2801 may be smaller than the second width 2802, but this is not a limitation.

[0110] Since the second welding surface 2740 is located on the first portion 2741, the second welding surface 2740 can act as a heat source when welding the first welding surface 1106 and the second welding surface 2740. By designing a heat insulation structure 2744 between the first portion 2741 and the third portion 2743, the rate at which heat applied to the first portion 2741 is transferred to the third portion 2743 through the narrower second portion 2742 can be reduced. This prevents the heat during welding from affecting other components in the optical system and also slows down heat loss in the welding area, thereby increasing welding efficiency.

[0111] In some embodiments, a wavy second welding surface and a perforated thermal insulation structure can be designed simultaneously. For example, Figure 11A This is a schematic diagram of circuit components 3700 according to some embodiments of this disclosure. Figure 11BThis is an enlarged view of the second component using circuit assembly 3700. In some embodiments, circuit assembly 3700 may include a first circuit element 3710, a second circuit element 3720, and a third circuit element 3730. For example, the first circuit element 3710 may include a first body 3711, a first connecting portion 3713, a second connecting portion 3714, and a bending portion 3715. The first connecting portion 3713 can be connected to the first body 3711 via the bending portion 3715, and the second connecting portion 3714 can be connected to the first body 3711. The second circuit element 3720 may include a second body 3721, a second solder portion 3722, and a third solder portion 3723. The second solder portion 3722 and the third solder portion 3723 are connected to the second body 3721. The third circuit element 3730 may include a fourth solder portion 3731. The first electronic component 1802 and the second electronic component 1804 are electrically connected to the first body 3711 of the first circuit element 3710, and the first circuit element 3710 is electrically insulated from the second circuit element 3720, the third circuit element 3730, and the outer frame 1100 (first assembly), while the second circuit element 3720 and the third circuit element 3730 are electrically connected to the outer frame 1100.

[0112] In some embodiments, the first connecting portion 3713, the second connecting portion 3714, the second welding portion 3722, the third welding portion 3723, and the fourth welding portion 3731 may be exposed from the base 1200. For example, the first connecting portion 3713, the second welding portion 3722, the third welding portion 3723, and the fourth welding portion 3731 may be exposed from the body 1210, while the second connecting portion 3714 may be disposed on the wall 1220. In some embodiments, when viewed from a fourth direction, the second connecting portion 3714 extends in a second direction and may be exposed from and overlap with the wall 1220. When viewed from a first direction, the first connecting portion 3713 may be exposed from the outer frame 1100 (first component) to allow the first connecting portion 3713 to be electrically connected to an external circuit.

[0113] In some embodiments, the second welding portion 3722 (or the third welding portion 3723, the fourth welding portion 3731) may include a first portion 3741, a second portion 3742, a third portion 3743, and a heat insulation structure 3744. The first portion 3741 is connected to the third portion 3743 through the second portion 3742, and the heat insulation structure 3744 and the second portion 3742 are arranged in a fourth direction. In some embodiments, when viewed from a second direction, the first portion 3741 is exposed above the base 1200, a portion of the second portion 3742 is exposed above the base 1200, while another portion of the second portion 3742 is embedded in the base 1200, and the third portion 3743 is embedded in the base 1200.

[0114] In some embodiments, the thermal insulation structure 3744 may be, for example, a hole. Therefore, when viewed from the second direction, the first welded surface 1106 may be exposed from the thermal insulation structure 3744. In the fourth direction, the second portion 3742 may have a first width 3801, and the thermal insulation structure 3744 may have a second width 3802. The first width 3801 may differ from the second width 3802; for example, the first width 3801 may be smaller than the second width 3802, but this disclosure is not limited thereto.

[0115] In some embodiments, the difference between circuit assembly 3700 and the aforementioned circuit assembly 2700 is that the second welding surface 3740 on the first portion 3741 has a wavy shape, while the second welding surface 2740 can be planar. This further increases the surface area of ​​the second welding surface 3740 and also prevents heat loss during welding, thereby further increasing the efficiency of welding the first welding surface 1106 and the second welding surface 3740.

[0116] In summary, embodiments of this disclosure provide an optical system including a first component and a second component. The first component includes a first weld portion. The second component is fixedly connected to the first component, and the second component includes a second weld portion. The first weld portion is fixedly connected to the second weld portion via welding. This increases the margin for welding the first and second components, reduces assembly problems caused by tolerances, and also increases welding efficiency.

[0117] The specific relative positions and size relationships of the components disclosed in this disclosure not only enable the drive mechanism to achieve ultra-thinness in a specific direction and overall miniaturization, but also further improve the optical quality of the system (such as shooting quality or depth sensing accuracy) by combining different optical modules, and further utilize each optical module to achieve a multi-stage anti-shake system to greatly improve the anti-shake effect.
