Description

Technical Field

[0001] This invention relates to an optical system, and more particularly to an optical system having multiple optical modules and a flexible portion. Background Technology

[0002] With the development of technology, many electronic devices today (such as computers or tablets) have the function of taking pictures or recording videos. As these electronic devices become more and more common, they are developing more stable and better optical quality, as well as moving towards convenient and thinner designs to provide users with more choices.

[0003] However, incorporating long-focal-length optical elements (such as lenses) into the aforementioned electronic devices increases their thickness, hindering their slimness and stability. Furthermore, due to varying imaging requirements, these electronic devices need functions such as optical image stabilization, focus adjustment, and light intake control. However, motors with different functions are not necessarily compatible.

[0004] Therefore, designing an optical system that enables electronic devices to be thinner and lighter, and more stable, while also providing better compatibility and the ability to be paired with a wider variety of modules, has become an important research topic. Summary of the Invention

[0092] It should be noted that the technical solutions provided in the different embodiments below can be substituted for, combined or mixed with each other to constitute another embodiment without violating the spirit of this disclosure.

[0093] This disclosure relates to an optical system having multiple optical modules and a flexible portion. A driving component drives a movable portion and optical elements to move, thereby adjusting the photographic imaging of the optical system to adapt to different photographic needs. The optical system of this disclosure has better compatibility, can be used with more lens drive modules, and simplifies the design of the control circuit.

[0094] First, please see Figures 1 to 2 , Figure 1 A perspective view of an example optical system 1 is provided in accordance with certain features of this disclosure. Figure 2 To illustrate certain features of this disclosure, a perspective view of example optical system 1 is provided, with housing 230 removed for illustrative purposes. Figure 3 An exploded perspective view of an example optical system 1 is provided in accordance with certain features of this disclosure.

[0095] The optical system 1 includes a first optical module 100, a second optical module 200, and a circuit assembly 300. The first optical module 100 carries a first optical element 10. The second optical module 200 carries a second optical element 20. The circuit assembly 300 is used to electrically connect to an external circuit (e.g., a lens drive device). The first optical module 100 is disposed above the second optical module 200, and the first optical module 100 can drive the first optical element 10 to move.

[0096] The first optical element 10 may consist of multiple optical blades. In this embodiment, the first optical element 10 has six optical blades. The six first optical elements 10 form an opening 10-c, through which incident light enters the second optical element 20. The actuation of the first optical element 10 will be described in detail below.

[0097] The second optical element 20 may be, for example, an optical lens. The second optical element 20 is mounted on a lens driving device (not shown) and achieves autofocus (AF) and optical image stabilization (OIS) functions through the lens driving device. The lens driving device has multiple driving circuit sections (not shown) for driving the lens driving device. The first optical module 100 may be supported on the second optical element 20 of the second optical module 200, and achieves autofocus and optical image stabilization functions as the second optical element 20 moves.

[0098] The first optical module 100 includes a first receiving space A1, a top cover 110, a light-shielding element 120, an upper frame 130, a plurality of guiding elements 140, a movable part 150, a driving assembly 160, a circuit board assembly 170, and a base 180.

[0099] The first receiving space A1 houses the first optical element 10. A movable part 150 is connected to the first optical element 10 and is movable relative to the upper frame 130 and the base 180. A drive assembly 160 drives the movable part 150. The upper frame 130 is fixedly connected to the base 180. The movable part 150 is movably connected to the upper frame 130 via a guide element 140. Incident light from the outside passes through the optical system 1 along an incident axis O1 and reaches the second optical element 20.

[0100] The top cover 110 is disposed on the first optical element 10. The first optical element 10 is located between the light-shielding element 120 and the top cover 110. The top cover 110 at least partially covers the first optical element 10, thereby protecting the components within the optical system 1 from external impacts. The light-shielding element 120 may be made of a light-absorbing material, such as SOMA.

[0101] When viewed along the incident axis O1 of the incident light, the upper frame 130, the movable part 150, the drive assembly 160, and the base 180 are arranged in sequence.

[0102] The drive assembly 160 includes multiple magnetic elements 162, multiple coils 164, and multiple magnetically conductive elements 166. In this embodiment, it includes two magnetic elements 162, two coils 164, and two magnetically conductive elements 166. Each coil 164 has two connection terminals 165 (see...). Figure 6 ), to be connected to circuit assembly 300.

[0103] A magnetic element 162 is disposed on the movable part 150. A coil 164 is disposed on the base 180. Through the electromagnetic driving force generated between the magnetic element 162 and the coil 164, the magnetic element 162 moves relative to the coil 164. Consequently, the movable part 150 moves relative to the base 180 and the upper frame 130 fixedly connected to the base 180, and the movable part 150 drives the movement of the first optical element 10. Therefore, the electromagnetic driving force generated between the magnetic element 162 and the coil 164 can drive the movable part 150 to move the first optical element 10 relative to the base 180 and the upper frame 130.

[0104] In this embodiment, four guide elements 140 are disposed between the movable part 150 and the upper frame 130, adjacent to the magnetic element 162. The movable part 150 is connected to the upper frame 130 via the four guide elements 140.

[0105] When the movable part 150 is driven by the drive assembly 160, the guide element 140 rolls between the upper frame 130 and the movable part 150, so that the movable part 150 moves smoothly relative to the upper frame 130.

[0106] The following are relative to Figures 3 to 5 Describe the movement of the movable part 150 relative to the upper frame 130 and the base 180. Figure 4 For certain features of this disclosure, a top view of the optical system 1 is provided, in which the first optical element 10 is located in a first position, with the housing 230 and the top cover 110 removed for illustrative purposes, and the first optical element 10 shown in dashed lines. Figure 5 For certain features of this disclosure, a top view of the optical system 1 is provided, in which the first optical element 10 is located in a second position, with the housing 230 and the top cover 110 removed for illustrative purposes, and the first optical element 10 shown in dashed lines.

[0107] The movable part 150 connects to six first optical elements 10. Each of the six first optical elements 10 has an aperture 10-a and an elongated aperture 10-b for connecting the movable part 150 and the upper frame 130, as will be explained further below.

[0108] The movable part 150 and the first optical element 10 are movable relative to the upper frame 130. The movable part 150 has a plurality of protrusions 150-b that pass through the elongated hole 10-b of the first optical element 10 and can move within the elongated hole 10-b.

[0109] The upper frame 130 has a plurality of protrusions 130-a that pass through the holes 10-a of the first optical element 10 and can rotate within the holes 10-a. The first optical element 10 is connected to the movable part 150 and the upper frame 130 via the protrusions 150-b and the protrusions 130-a, the elongated holes 10-b and the holes 10-a.

[0110] When the movable part 150 is driven by the drive assembly 160, the plurality of protrusions 150-b of the movable part 150 pass through the elongated hole 10-b of the first optical element 10 and move within the elongated hole 10-b. Meanwhile, the plurality of protrusions 130-a of the upper frame 130 pass through the hole 10-a of the first optical element 10 and rotate within the hole 10-a, thereby driving the movement of the first optical element 10. The size of the opening 10-c formed by the first optical element 10 can be adjusted by the movement of the first optical element 10.

[0111] exist Figure 4 In the first position shown, the opening 10-c formed by the first optical element 10 is small, so that a smaller amount of incident light can pass through the opening 10-c to reach the second optical element 20 in this position.

[0112] exist Figure 5In the second position shown, the opening 10-c formed by the first optical element 10 is relatively... Figure 4 The first position shown is large, so the second position allows more incident light to reach the second optical element 20 through the opening 10-c than the first position.

[0113] Please continue to refer to the following. Figure 3 The magnetic element 166 corresponds to the magnetic element 162 and is disposed on the circuit board assembly 170, corresponding to the coil 164 and the magnetic element 162. The magnetic element 166 and the magnetic element 162 provide a magnetic attraction force for the movable part 150 toward the guide element 140, so that the movable part 150 rests against the guide element 140, thereby allowing it to move stably relative to the upper frame 130.

[0114] The second optical module 200 includes a second receiving space A2, a protective frame 210, a fixing frame 220, and a housing 230. The protective frame 210 receives the second optical element 20.

[0115] The protective frame 210 has a first sidewall 211 and a second sidewall 212. The first sidewall 211 is at least partially located between the second receiving space A2 and the circuit assembly 300. The first optical module 100 is at least partially located in the second receiving space A2. The first sidewall 211 may be at least partially covered with a light-shielding material, such as SOMA. The inner side of the housing 230 may also be at least partially covered with a light-shielding material, such as SOMA.

[0116] Please refer to the following: Figure 3 as well as Figure 6 . Figure 6 In accordance with certain features of this disclosure, example optical system 1 along Figure 1 The cross-sectional view of line BB. The housing 230 includes a first housing space 231, a second housing space 232, and a third housing space 233. The first housing space 231 connects to both the second housing space 232 and the third housing space 233. The first housing space 231 accommodates the protective frame 210, the second housing space 232 accommodates a portion of the circuit assembly 300, and the third housing space 233 accommodates the fixing frame 220. When viewed along a direction parallel to the first sidewall 211, the first housing space 231 and the second housing space 232 do not overlap. When viewed along a direction parallel to the second sidewall 212, the first housing space 231 and the third housing space 233 do not overlap. When viewed along a direction normal to the second sidewall 212, the first housing space 231 and the third housing space 233 at least partially do not overlap, and the second housing space 232 and the third housing space 233 at least partially do not overlap. The structural design of the housing 230 can effectively protect the fixing frame 220 and the circuit components 300, making them less susceptible to damage from external impacts and improving the reliability of the optical system 1.

[0117] The second sidewall 212 is at least partially located between the second receiving space A2 and the circuit assembly 300. The first sidewall 211 and the second sidewall 212 are not parallel to each other. The second sidewall 212 is attached to the fixing frame 220. The fixing frame 220 has a groove 222 (see...). Figure 2 ), accommodating some circuit components 300.

[0118] Please refer to the following: Figure 3 as well as Figure 7 . Figure 7 For the purposes of this disclosure, a top view of an example optical system 1 is provided.

[0120] Coil 164 is fixed to coil end 172. Control component 176 is fixed to one of the two coil ends 172. In this embodiment, control component 176 is electrically connected to coil 164, and then electrically connected to circuit component 174 via connection end 165. Circuit component 174 is electrically connected to circuit assembly 300, and then electrically connected to external circuit via circuit assembly 300.

[0121] The circuit assembly 300 is electrically connected to the drive assembly 160 via the circuit board assembly 170, and the circuit assembly 300 is not disposed in the second receiving space A2. The circuit assembly 300 is disposed on the first sidewall 211 and the fixing frame 220.

For example, input terminal 311 is movably connected to output terminal 312 via flexible portion 313, input terminal 321 is movably connected to output terminal 322 via flexible portion 323, input terminal 331 is movably connected to output terminal 332 via flexible portion 333, and input terminal 331 is movably connected to output terminal 332 via flexible portion 333. The flexible portions are made of flexible material, so the respective input terminals and output terminals can move relative to each other. For example, input terminal 311 can move relative to output terminal 312, input terminal 321 can move relative to output terminal 322, input terminal 331 can move relative to output terminal 332, and input terminal 341 can move relative to output terminal 342.

The outer ends 314, 324, 334, and 344 are accommodated within the first groove space 2221, but the outer ends 314, 324, 334, and 344 are not accommodated within the second groove space 2222. When along the normal direction parallel to the second sidewall 212 (e.g., the -X-axis)... When viewed from the (direction) perspective, the first trench space 2221 at least partially overlaps with the external terminals 314, 324, 334, and 344, and the second trench space 2222 at least partially overlaps with the external terminals 314, 324, 334, and 344. The area of ​​overlap between the external terminals 314, 324, 334, and 344 and the first trench space 2221 is greater than the area of ​​overlap between the external terminals 314, 324, 334, and 344 and the second trench space 2222. Through the structural design of the first trench space 2221 and the second trench space 2222, the electrical connection between the external terminals 314, 324, 334, and 344 and the external circuit can be made more convenient and reliable.

[0125] When viewed along the direction perpendicular to the first sidewall 211, the fixed frame 220 does not overlap with the flexible parts 313, 323, 333, and 343.

[0126] Please refer to the following: Figure 7 , Figure 8 as well as Figure 9 . Figure 8 In accordance with certain features of this disclosure, example optical system 1 along Figure 2The cross-sectional view of line AA, with the outer shell 230 removed for illustrative purposes. Figure 9 In accordance with certain features of this disclosure, example optical system 1 along Figure 2 A cross-sectional view of line CC, with the outer shell 230 removed for illustrative purposes.

[0127] exist Figure 8 As can be seen, the height H2 of the fixed frame 220 is greater than the height H1 of the protective frame 210. When the first optical module 100 moves relative to the second optical module 200, the difference between the height H2 of the fixed frame 220 and the height H1 of the protective frame 210 provides movement space, and the flexible portions 313, 323, 333, and 343 of the circuit assembly 300 provide elasticity during movement.

[0128] The length L2 of the fixed frame 220 is greater than the length L2 of the protective frame 210. During assembly, the protective frame 210 is placed inside the fixed frame 220, that is, the second sidewall 212 is fixedly attached to the fixed frame 220 and covered by the fixed frame 220. The fixed frame 220 includes a main frame 224, a top frame 226, and a side frame 228. The main frame 224 corresponds to the second sidewall 212, and a groove 222 is formed on the main frame 224. The main frame 224 connects both the top frame 226 and the side frame 228. Output terminals 312, 322, 332, and 342 can be disposed on the top frame 226. The side frame 228 does not contact the circuit assembly 300. Figure 9 As can be seen, when viewed along the direction perpendicular to the first side wall 211, the main frame 224, the side frame 228, and the protective frame 210 do not overlap, while the top frame 226 at least partially overlaps with the protective frame 210. When viewed along the direction parallel to the first side wall 211 and the second side wall 212 (e.g., the +Y axis direction), the main frame 224, the top frame 226, and the protective frame 210 do not overlap, while the side frame 228 at least partially overlaps with the protective frame 210. This structural design ensures that the fixed frame 220 can be reliably mounted on the protective frame 210.

[0129] Through the above embodiments, it is advantageous to mount the optical system 1 on the lens driving device. Specifically, in this embodiment, the lens driving device equipped with the second optical element 20 does not require additional circuitry for driving the moving part 150 and the first optical element 10, thus avoiding complex structural design of the lens driving device. At the same time, in conjunction with the circuit assembly 300 of the circuit board assembly 170 of the optical system 1, the driving circuit of the lens driving device can be arranged in the groove 222 of the fixing frame 220, making the circuit design for controlling the optical system 1 and the lens driving device more convenient and simpler.

[0130] In summary, this invention provides an optical system comprising a first optical module, a second optical module, and a circuit assembly. The movement of the drive assembly causes the movable part to move relative to the base. This allows for adjustment of the position of the blades and the amount of incident light reaching the optical elements, adapting to different photographic needs and providing more stable optical quality.

[0131] Meanwhile, the design of the protective frame and circuit components makes it easier to mount the optical system on the lens drive device, ensuring that the structural design of the moving part of the optical system and the first optical element is not affected by the lens drive device, and can be used with lens drive devices of different sizes. Furthermore, the circuit design for driving the movement of the moving part and the first optical element can be independent of the circuit design of the lens drive device, simplifying the design of the control circuit.
