Description

Technical Field

[0001] This disclosure relates to an optical element driving mechanism. 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.

The optical system 1000 may be, for example, a periscope-type camera module, and mainly includes an optical element driving mechanism 1100, a first optical module 1200, and an optical path adjustment element 1300. The optical element driving mechanism 1100 may include a first outer frame 1110 and a first base 1120, which together form a first receiving space 1140 for accommodating a first optical element 1130. In some embodiments, the material of the first outer frame 1110 may include a metallic material, while the material of the first base 1120 may include a non-metallic material, such as plastic.

The second base 1220 may include a second base plate 1221, which has a plate-like structure and is parallel to the second top wall 1211 but not parallel to the first base plate 1121. It should be noted that the first top wall 1111 may face the second side wall 1212, and the first top wall 1111 may be parallel to the second side wall 1212. The first top wall 1111 may have a first opening 1113, and the second side wall 1212 may have a second opening 1213, with the first opening 1113 adjacent to the second side wall 1212 and the second opening 1213 adjacent to the first top wall 1111. In other words, the first opening 1113 may be adjacent to the second opening 1213 to allow light to pass through the first opening 1113 and the second opening 1213 to reach the first optical element 1130. In some embodiments, the maximum size of the first opening 1113 and the maximum size of the second opening 1213 on the first axis 1001 may be different from each other to accommodate various different light paths.

The filter element 2310, for example, may be a filter sheet, exposed through the first opening 2113 to filter out light of specific wavelengths (e.g., infrared, ultraviolet, etc.) to ensure that only certain wavelengths of light can pass through and reach the first optical element 2300. The filter element 2310 may be disposed on the first carrier element 2210, which may be disposed on the second carrier element 2220. The second carrier element 2220 and the first optical element 2300 may be disposed on the first circuit assembly 2410. The first circuit assembly 2410 may be disposed on the third carrier element 2230. The third carrier element 2230 may be movably connected to the first base 2120 via the connecting assembly 2600. In other words, the movable part 2200 may be used to carry the first optical element 2300 and may be movably connected to the fixed part 2100 via the connecting assembly 2600. The first optical element 2300 may, for example, include a photosensitive element. The first connecting element 2610 of the connecting assembly 2600 may include, for example, a spring, and the second connecting element 2620 may include, for example, a hanging loop wire, to movably connect the fixed part 2100 and the movable part 2200. In some embodiments, the optical element driving mechanism 2000 may include four first connecting elements 2610 and four second connecting elements 2620 located at the four corners of the optical element driving mechanism 2000 to uniformly maintain the position of the movable part 2200 relative to the fixed part 2100.

[0122] The first magnetic element 2501, the second magnetic element 2502, and the third magnetic element 2503 of the drive assembly 2500 can be disposed on the third support element 2230, while the first coil 2511, the second coil 2512, and the third coil 2513 can be disposed on the second circuit assembly 2420. The second circuit assembly 2420 can be disposed on the first base 2120. The first magnetic element 2501, the second magnetic element 2502, and the third magnetic element 2503 can be, for example, magnets, and can generate electromagnetic driving force with the first coil 2511, the second coil 2512, and the third coil 2513 respectively when energized, so as to drive the movable part 2200 to move relative to the fixed part 2100. In some embodiments, the positions of the first magnetic element 2501, the second magnetic element 2502, the third magnetic element 2503 and the first coil 2511, the second coil 2512, the third coil 2513 can also be interchanged. For example, the first magnetic element 2501, the second magnetic element 2502, the third magnetic element 2503 can be disposed on the fixed part 2100, while the first coil 2511, the second coil 2512, the third coil 2513 can be disposed on the movable part 2200, depending on the design requirements.

[0123] Figure 2E This is a top view of some components of the optical element drive mechanism 2000. The first circuit assembly 2410 provides the energy required for the operation of the first optical element 2300 and allows the first optical element 2300 to be movably connected to the fixing part 2100 via the first circuit assembly 2410. The second circuit assembly 2420 provides the energy required for the operation of the first coil 2511, the second coil 2512, and the third coil 2513. For example, such as... Figure 2E As shown, when viewed along the optical axis 2001, the first circuit assembly 2410 surrounds the movable part 2200 and includes a first segment 2411, a second segment 2412, a third segment 2413, a fourth segment 2414, a fifth segment 2415, a sixth segment 2416, and a seventh segment 2417 connected in sequence.

[0124] The first segment 2411, the third segment 2413, the fifth segment 2415, and the seventh segment 2417 may extend along the second axis 2002, while the second segment 2412, the fourth segment 2414, and the sixth segment 2416 may extend along the third axis 2003. The optical axes 2001, 2002, and 2003 may be perpendicular to each other. In other words, the first segment 2411 and the second segment 2412 are not parallel. The first segment 2411, the second segment 2412, the third segment 2413, the fourth segment 2414, the fifth segment 2415, the sixth segment 2416, and the seventh segment 2417 have a plate-like structure. In some embodiments, when the optical element driving mechanism 2000 replaces the aforementioned optical element driving mechanism 1100 in the optical system 1000, the third axis 2003 and the first axis 1002 may be parallel to each other.

[0125] In some embodiments, the second segment 2412, the third segment 2413, the fourth segment 2414, the fifth segment 2415, and the sixth segment 2416 do not directly contact the fixed portion 2100 and the movable portion 2200; that is, there are gaps between the second segment 2412, the third segment 2413, the fourth segment 2414, the fifth segment 2415, and the sixth segment 2416 and the fixed portion 2100 and the movable portion 2200, to increase the durability of the first circuit element 2410. When viewed along the optical axis 2001, the optical element driving mechanism 2000 has an elongated structure and extends along the second axis 2002.

[0126] In some embodiments, the third segment 2413 has a plate-like structure, and its normal vector is in a different direction from the normal vector of the first segment 2411, which also has a plate-like structure. For example, the normal vector of the third segment 2413 may be parallel to the third axis 2003, while the normal vector of the first segment 2411 may be parallel to the optical axis 2001. In other words, the first segment 2411 and the third segment 2413 are not parallel. In some embodiments, the third segment 2413 and the fourth segment 2414 extend in different directions, i.e., the third segment 2413 and the fourth segment 2414 are not parallel. In some embodiments, the fifth segment 2415 is not parallel to the fourth segment 2414, the sixth segment 2416 is not parallel to the fifth segment 2415, and the seventh segment 2417 is not parallel to the sixth segment 2416.

[0127] In some embodiments, the optical element drive mechanism 2000 may further include a first damping element 2701, a second damping element 2702, a third damping element 2703, a fourth damping element 2704, a fifth damping element 2705, and a sixth damping element 2706. The first damping element 2701, the second damping element 2702, the third damping element 2703, the fourth damping element 2704, the fifth damping element 2705, and the sixth damping element 2706 may be made of resin and can be used to absorb abnormal vibrations of the movable part 2200 relative to the fixed part 2100. The first damping element 2701 may directly contact the first bend 2431 of the first circuit assembly 2410 and the fixed part 2100. When viewed along the optical axis 2001, the optical element drive mechanism 2000 has a polygonal structure, and the first damping element 2701 is located at the first corner 2112 of the optical element drive mechanism 2000.

[0128] In some embodiments, the second damping element 2702 is located on the first side 2111 of the optical element drive mechanism 2000 and directly contacts the third segment 2413 and the movable part 2200 of the first circuit assembly 2410. In some embodiments, when viewed along the optical axis 2001, the third damping element 2703 is located at the second corner 2114 of the optical element drive mechanism 2000 and directly contacts the second bend 2432 and the connecting assembly 2600 (e.g., the first connecting element 2610) of the first circuit assembly 2410. The fourth damping element 2704, the fifth damping element 2705, and the sixth damping element 2706 may be located in opposite positions to the third damping element 2703, the second damping element 2702, and the first damping element 2701 (e.g., on both sides of the second axis 2002), which will not be described further here.

[0129] Figure 2F This is a top view of some components of the optical element drive mechanism 2000. (Example) Figure 2F As shown, when viewed along the optical axis 2001 (parallel to the winding axis of the first coil 2511, the second coil 2512, and the third coil 2513), the first coil 2511, the second coil 2512, and the third coil 2513 have elongated structures, and the first coil 2511 and the third coil 2513 extend along the second axis 2002, while the second coil 2512 extends along the third axis 2003. The first coil 2511, the second coil 2512, and the third coil 2513 are arranged along the second axis 2002.

[0130] The first magnetic element 2501, the second magnetic element 2502, and the third magnetic element 2503 correspond to the first coil 2511, the second coil 2512, and the third coil 2513, respectively. That is, the first magnetic element 2501, the second magnetic element 2502, and the third magnetic element 2503 are also arranged along the second axis 2002 and at least partially overlap in the direction of the optical axis 2001. Furthermore, the centers of the first magnetic element 2501 and the third magnetic element 2503 do not overlap with the center of the first optical element 2300, while the center of the second magnetic element 2502 at least partially overlaps with the center of the first optical element 2300. In other words, when viewed along the optical axis 2001, the distance between the center of the first magnetic element 2501 and the center of the first optical element 2300 is greater than the distance between the center of the second magnetic element 2502 and the center of the first optical element 2300. It should be noted that this feature is not limited to this embodiment and may also be present in other embodiments, depending on design requirements. In some embodiments, in the direction in which the second axis 2002 extends, the first coil 2511, the second coil 2512, and the third coil 2513 at least partially overlap each other.

[0131] The first magnetic element 2501 and the first coil 2511 can be used to generate a first driving force, the second magnetic element 2502 and the second coil 2512 can be used to generate a second driving force, and the third magnetic element 2503 and the third coil 2513 can be used to generate a third driving force. It should be noted that the directions of the first and third driving forces can be parallel to the third axis 2003, while the direction of the second driving force can be parallel to the second axis 2002. In other words, the directions of the first and third driving forces can be parallel to each other, for example, in the same or opposite directions, while the directions of the first and third driving forces can be perpendicular to the direction of the second driving force.

[0132] The first sensing element 2521, the second sensing element 2522, and the third sensing element 2523 can be used to sense the movement of the movable part 2200 relative to the fixed part 2100, such as the linear movement of the movable part 2200 relative to the fixed part 2100. The first sensing element 2521, the second sensing element 2522, and the third sensing element 2523 may include, for example, a Hall effect sensor, a magnetoresistance effect sensor (MR sensor), a giant magnetoresistance effect sensor (GMR sensor), a tunneling magnetoresistance effect sensor (TMR sensor), or a fluxgate sensor.

[0133] In some embodiments, the first coil 2511, the second coil 2512, and the third coil 2513 surround the first sensing element 2521, the second sensing element 2522, and the third sensing element 2523, respectively. Furthermore, since the first sensing element 2521 and the third sensing element 2523 are arranged along the second axis 2002, the first sensing element 2521 and the third sensing element 2523 can also be used to sense the rotation of the movable part 2200 relative to the fixed part 2100.

[0134] like Figure 2D As shown, in the direction of extension of the optical axis 2001, the first optical element 2300 is located between the first opening 2113 and the first coil 2513. In other words, in the direction of extension of the optical axis 2001, the first optical element 2300 is located between the drive assembly 2500 and the first opening 2113, so as to allow light to pass through the first opening 2113 and reach the first optical element 2300. Since the drive assembly 2500 is located on the side of the first optical element 2300 facing away from the first opening 2113, the back focal distance of the optical system 1000 in which the optical element drive mechanism 2000 is provided can be reduced, and the size of the optical element drive mechanism 2000 in a certain direction can also be reduced, thereby achieving miniaturization.

[0135] Figure 3A This is a schematic diagram of the optical element drive mechanism 3000. Figure 3B This is an exploded view of the optical element drive mechanism 3000. Figure 3C This is a top view of the optical element drive mechanism 3000. Figure 3D It is along Figure 3C The second axis 3002 is shown in a cross-sectional view. The optical axis 3001, the second axis 3002, and the third axis 3003 may be perpendicular to each other and may pass through the center of the optical element drive mechanism 3000.

[0136] The optical element driving mechanism 3000 can be used to replace the aforementioned optical element driving mechanism 1100 and is provided in the optical system 1000. The optical element driving mechanism 3000 mainly includes a first outer frame 3110, a first base 3120, a filter element 3310, a first carrier element 3210, a second carrier element 3220, a third carrier element 3230, a first optical element 3300, a first circuit assembly 3410, a second circuit assembly 3420, a first magnetic element 3501, a second magnetic element 3502, a third magnetic element 3503, a first coil 3511, a second coil 3512, a third coil 3513, a first sensing element 3521, a second sensing element 3522, a third sensing element 3523, a first connecting element 3610, and a second connecting element 3620 arranged on the optical axis 3001.

[0137] In some embodiments, the first outer frame 3110 and the first base 3120 can be collectively referred to as the fixing part 3100, the first bearing element 3210, the second bearing element 3220, and the third bearing element 3230 can be collectively referred to as the moving part 3200, the first magnetic element 3501, the second magnetic element 3502, the third magnetic element 3503, the first coil 3511, the second coil 3512, and the third coil 3513 can be collectively referred to as the driving assembly 3500, and the first connecting element 3610 and the second connecting element 3620 can be collectively referred to as the connecting assembly 3600.

[0138] The first outer frame 3110 may have a first opening 3113. The filter element 3310, for example, may be a filter that can be exposed through the first opening 3113 and used to filter out light of specific wavelengths (e.g., infrared light, ultraviolet light, etc.) to ensure that only certain wavelengths of light can pass through and reach the first optical element 3300. The filter element 3310 may be disposed on the first carrier element 3210, and the first carrier element 3210 may be disposed on the second carrier element 3220. The second carrier element 3220 and the first optical element 3300 may be disposed on the first circuit assembly 3410. The first circuit assembly 3410 may be disposed on the third carrier element 3230. The third carrier element 3230 may be movably connected to the first base 3120 via the connecting assembly 3600. In other words, the movable part 3200 may be used to carry the first optical element 3300 and may be movably connected to the fixed part 3100 via the connecting assembly 3600. The first optical element 3300 may include, for example, a photosensitive element. The first connecting element 3610 of the connecting assembly 3600 may include, for example, a spring, and the second connecting element 3620 may include, for example, a hanging loop wire, to movably connect the fixed part 3100 and the movable part 3200. In some embodiments, the optical element driving mechanism 3000 may include four first connecting elements 3610 and four second connecting elements 3620 located at the four corners of the optical element driving mechanism 3000 to uniformly maintain the position of the movable part 3200 relative to the fixed part 3100.

[0139] The first magnetic element 3501, the second magnetic element 3502, and the third magnetic element 3503 of the drive assembly 3500 can be disposed on the third support element 3230, while the first coil 3511, the second coil 3512, and the third coil 3513 can be disposed on the second circuit assembly 3420. The second circuit assembly 3420 can be disposed on the first base 3120. The first magnetic element 3501, the second magnetic element 3502, and the third magnetic element 3503 can be, for example, magnets, and can generate electromagnetic driving force with the first coil 3511, the second coil 3512, and the third coil 3513 respectively when energized, so as to drive the movable part 3200 to move relative to the fixed part 3100. In some embodiments, the positions of the first magnetic element 3501, the second magnetic element 3502, the third magnetic element 3503 and the first coil 3511, the second coil 3512, the third coil 3513 can also be interchanged. For example, the first magnetic element 3501, the second magnetic element 3502, and the third magnetic element 3503 can be disposed on the fixed part 3100, while the first coil 3511, the second coil 3512, and the third coil 3513 can be disposed on the movable part 3200, depending on the design requirements.

[0140] It should be noted that the configuration of the first magnetic element 3501, the second magnetic element 3502, the third magnetic element 3503, the first coil 3511, the second coil 3512, the third coil 3513, the first sensing element 3521, the second sensing element 3522, and the third sensing element 3523 may be the same as or similar to the configuration of the first magnetic element 2501, the second magnetic element 2502, the third magnetic element 2503, the first coil 2511, the second coil 2512, the third coil 2513, the first sensing element 2521, the second sensing element 2522, and the third sensing element 2523, and will not be described again here.

[0141] The aforementioned first circuit assembly 2410 may include multiple segments surrounding the movable portion 2200, but this disclosure is not limited thereto. For example, Figure 3E This is a schematic diagram of some components of the optical element driving mechanism 3000, mainly showing the first circuit assembly 3410 and other components. The first circuit assembly 3410 can be disposed on the third carrier element 3230 of the movable part 3200, and its externally connected segment does not surround the movable part 3200. As a result, the required circuit length can be reduced, thereby achieving miniaturization.

[0142] Figure 4A This is a schematic diagram of the optical element drive mechanism 4000. Figure 4B This is an exploded view of the optical element drive mechanism 4000. Figure 4C This is a top view of the optical element drive mechanism 4000. Figure 4D It is along Figure 4CThe second axis 4002 is shown in a cross-sectional view. The optical axis 4001, the second axis 4002, and the third axis 4003 may be perpendicular to each other and may pass through the center of the optical element drive mechanism 4000.

[0143] The optical element driving mechanism 4000 can be used to replace the aforementioned optical element driving mechanism 1100 and is provided in the optical system 1000. The optical element driving mechanism 4000 mainly includes a first outer frame 4110, a first base 4120, a filter element 4310, a first carrier element 4210, a second carrier element 4220, a third carrier element 4230, a first optical element 4300, a first circuit assembly 4410, a second circuit assembly 4420, a first magnetic element 4501, a second magnetic element 4502, a third magnetic element 4503, a fourth magnetic element 4504, a first coil 4511, a second coil 4512, a third coil 4513, a fourth coil 4514, a first sensing element 4521, a second sensing element 4522, a third sensing element 4523, a fourth sensing element 4524, a first connecting element 4610, and a second connecting element 4620, all arranged on the optical axis 4001.

[0144] In some embodiments, the first outer frame 4110 and the first base 4120 can be collectively referred to as the fixing part 4100, the first bearing element 4210, the second bearing element 4220, and the third bearing element 4230 can be collectively referred to as the moving part 4200, the first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, the fourth magnetic element 4504, the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 can be collectively referred to as the driving assembly 4500, and the first connecting element 4610 and the second connecting element 4620 can be collectively referred to as the connecting assembly 4600.

[0145] The first base 4120 may have a first opening 4113. A filter element 4310, such as a filter, may be exposed through the first opening 4113 to filter out light of specific wavelengths (e.g., infrared, ultraviolet, etc.) to ensure that only certain wavelengths of light can pass through and reach the first optical element 4300. The filter element 4310 may be disposed on the first carrier element 4210, which may be disposed on the second carrier element 4220. The second carrier element 4220 and the first optical element 4300 may be disposed on the first circuit assembly 4410. The first circuit assembly 4410 may be disposed on the third carrier element 4230. The third carrier element 4230 may be movably connected to the first base 4120 via a connecting assembly 4600. In other words, the movable part 4200 can be used to carry the first optical element 4300 and may be movably connected to the fixed part 4100 via the connecting assembly 4600. The first optical element 4300 may, for example, include a photosensitive element. The first connecting element 4610 of the connecting assembly 4600 may include, for example, a spring, and the second connecting element 4620 may include, for example, a hanging loop wire, to movably connect the fixed part 4100 and the movable part 4200. In some embodiments, the optical element driving mechanism 4000 may include four first connecting elements 4610 and four second connecting elements 4620 located at the four corners of the optical element driving mechanism 4000 to uniformly maintain the position of the movable part 4200 relative to the fixed part 4100.

[0146] The first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, and the fourth magnetic element 4504 of the drive assembly 4500 can be disposed on the third support element 4230, while the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 can be disposed on the second circuit assembly 4420. The second circuit assembly 4420 can be disposed on the first base 4120. The first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, and the fourth magnetic element 4504 can be, for example, magnets, and can generate electromagnetic driving force with the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 respectively when energized, so as to drive the movable part 4200 to move relative to the fixed part 4100. In some embodiments, the positions of the first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, and the fourth magnetic element 4504, and the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 can also be interchanged. For example, the first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, and the fourth magnetic element 4504 can be disposed on the fixed part 4100, while the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 can be disposed on the movable part 4200, depending on the design requirements.

[0147] Figure 4E This is a top view of some components of the 4000 optical element drive mechanism. (Example) Figure 4E As shown, when viewed along the optical axis 4001 (parallel to the winding axis of the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514), the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 have elongated structures. The first coil 4511 and the third coil 4513 extend along the second axis 4002, while the second coil 4512 and the fourth coil 4514 extend along the third axis 4003. The first coil 4511, the second coil 4512, the fourth coil 4514, and the third coil 4513 are arranged along the second axis 4002.

[0148] The first magnetic element 4501, the second magnetic element 4502, the third magnetic element 4503, and the fourth magnetic element 4504 correspond to the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514, respectively. That is, the first magnetic element 4501, the second magnetic element 4502, the fourth magnetic element 4504, and the third magnetic element 4503 are also arranged along the second axis 4002 and at least partially overlap in the direction of the optical axis 4001. Furthermore, when viewed along the optical axis 4002, the distance between the center of the first magnetic element 4501 and the center of the first optical element 4300 is greater than the distance between the center of the second magnetic element 4502 and the center of the first optical element 4300. It should be noted that this feature is not limited to this embodiment and may also be present in other embodiments, depending on design requirements. In some embodiments, in the direction extending along the second axis 4002, the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 at least partially overlap each other.

[0149] The first magnetic element 4501 and the first coil 4511 can be used to generate a first driving force, the second magnetic element 4502 and the second coil 4512 can be used to generate a second driving force, the third magnetic element 4503 and the third coil 4513 can be used to generate a third driving force, and the fourth magnetic element 4504 and the fourth coil 4514 can be used to generate a fourth driving force. It should be noted that the directions of the first and third driving forces can be parallel to the second axis 4002, while the directions of the second and fourth driving forces can be parallel to the third axis 4003. In other words, the directions of the first and third driving forces can be parallel to each other, and the directions of the second and fourth driving forces can be parallel to each other, for example, in opposite directions, while the directions of the first and third driving forces can be perpendicular to the directions of the second and fourth driving forces. Furthermore, when viewed along the optical axis 4001, the center of the first optical element 4300 is located between the first magnetic element 4501 and the third magnetic element 4503, and also between the second magnetic element 4502 and the fourth magnetic element 4504.

[0150] It should be noted that in this embodiment, the drive assembly 4500 is located on the side of the first optical element 4300 facing the first opening 4113, which can increase the back focal distance of the optical system 1000 on which the optical element drive mechanism 4000 is provided, and can also reduce the size of the optical element drive mechanism 4000 in a certain direction, thereby achieving miniaturization.

[0151] The first sensing element 4521, the second sensing element 4522, the third sensing element 4523, and the fourth sensing element 4524 can be used to sense the movement of the movable part 4200 relative to the fixed part 4100, such as the linear movement of the movable part 4200 relative to the fixed part 4100. The first sensing element 4521, the second sensing element 4522, the third sensing element 4523, and the fourth sensing element 4524 may include, for example, a Hall effect sensor, a magnetoresistive effect sensor, a giant magnetoresistive effect sensor, a tunneling magnetoresistive effect sensor, or a magnetic flux sensor.

[0152] In some embodiments, the first coil 4511, the second coil 4512, the third coil 4513, and the fourth coil 4514 surround the first sensing element 4521, the second sensing element 4522, the third sensing element 4523, and the fourth sensing element 4524, respectively. Furthermore, since the first sensing element 4521 and the third sensing element 4523 are arranged along the second axis 4002, they can also be used to sense the rotation of the movable part 4200 relative to the fixed part 4100. The second sensing element 4522 and the fourth sensing element 4524 are also arranged along the second axis 4002, and they can also be used to sense the rotation of the movable part 4200 relative to the fixed part 4100.

Figure 5C This is a top view of the 5000 optical element drive mechanism. Figure 5D It is along Figure 5C The second axis 5002 is shown in a cross-sectional view. The optical axis 5001, the second axis 5002, and the third axis 5003 may be perpendicular to each other and may pass through the center of the optical element drive mechanism 4000.

[0154] The optical element driving mechanism 5000 can be used to replace the aforementioned optical element driving mechanism 1100 and is provided in the optical system 1000. The optical element driving mechanism 5000 mainly includes a first outer frame 5110, a first base 5120, a filter element 5310, a first carrier element 5210, a second carrier element 5220, a third carrier element 5230, a first optical element 5300, a first circuit assembly 5410, a second circuit assembly 5420, a third circuit assembly 5430, a first magnetic element 5501, a second magnetic element 5502, a third magnetic element 5503, a fourth magnetic element 5504, a first coil 5511, a second coil 5512, a third coil 5513, a fourth coil 5514, a first sensing element 5521, a second sensing element 5522, a third sensing element 5523, a fourth sensing element 5524, a first connecting element 5610, and a second connecting element 5620, all arranged on the optical axis 5001.

[0155] In some embodiments, the first outer frame 5110 and the first base 5120 can be collectively referred to as the fixing part 5100, the first bearing element 5210, the second bearing element 5220, and the third bearing element 5230 can be collectively referred to as the moving part 5200, the first magnetic element 5501, the second magnetic element 5502, the third magnetic element 5503, the fourth magnetic element 5504, the first coil 5511, the second coil 5512, the third coil 5513, and the fourth coil 5514 can be collectively referred to as the driving assembly 5500, and the first connecting element 5610 and the second connecting element 5620 can be collectively referred to as the connecting assembly 5600.

[0156] The first base 5120 may have a first opening 5113. A filter element 5310, such as a filter, may be exposed through the first opening 5113 to filter out light of specific wavelengths (e.g., infrared, ultraviolet, etc.) to ensure that only certain wavelengths of light can pass through and reach the first optical element 5300. The filter element 5310 may be disposed on the first carrier element 5210, which may be disposed on the second carrier element 5220. The second carrier element 5220 and the first optical element 5300 may be disposed on the first circuit assembly 5410. The first circuit assembly 5410 may be disposed on the third carrier element 5230. The third carrier element 5230 may be movably connected to the first base 5120 via a connecting assembly 5600. In other words, the movable part 5200 may be used to carry the first optical element 5300 and may be movably connected to the fixed part 5100 via the connecting assembly 5600. The first optical element 5300 may, for example, include a photosensitive element. The first connecting element 5610 of the connecting assembly 5600 may include, for example, a spring, and the second connecting element 5620 may include, for example, a hanging loop wire, to movably connect the fixed part 5100 and the movable part 5200. In some embodiments, the optical element driving mechanism 5000 may include four first connecting elements 5610 and four second connecting elements 5620 located at the four corners of the optical element driving mechanism 5000 to uniformly maintain the position of the movable part 5200 relative to the fixed part 5100.

[0157] Figure 5EThis is a top view of some components of the optical element driving mechanism 5000. The first magnetic element 5501, second magnetic element 5502, third magnetic element 5503, and fourth magnetic element 5504 of the driving assembly 5500 can be disposed on the third support element 5230. For example, the first magnetic element 5501 and the third magnetic element 5503 can be disposed on the side of the third support element 5230 facing the first base 5120, while the second magnetic element 5502 and the fourth magnetic element 5504 can be disposed on the side of the third support element 5230 facing the first outer frame 5110. The first coil 5511 and the third coil 5513 can be disposed on the third circuit assembly 5430, while the second coil 5512 and the fourth coil 5514 can be disposed on the second circuit assembly 5420. The second circuit assembly 5420 can be disposed on the first base 5120. The third circuit assembly 5430 can be disposed on the first outer frame 5110. The first magnetic element 5501, the second magnetic element 5502, the third magnetic element 5503, and the fourth magnetic element 5504 can be, for example, magnets, and can generate electromagnetic driving force with the first coil 5511, the second coil 5512, the third coil 5513, and the fourth coil 5514 when energized, respectively, to drive the movable part 5200 to move relative to the fixed part 5100. In some embodiments, the positions of the first magnetic element 5501, the second magnetic element 5502, the third magnetic element 5503, and the fourth magnetic element 5504 and the first coil 5511, the second coil 5512, the third coil 5513, and the fourth coil 5514 can also be interchanged. For example, the first magnetic element 5501, the second magnetic element 5502, the third magnetic element 5503, and the fourth magnetic element 5504 can be disposed on the fixed part 5100, while the first coil 5511, the second coil 5512, the third coil 5513, and the fourth coil 5514 can be disposed on the movable part 5200, depending on design requirements.

[0158] Since the first magnetic element 5501, the third magnetic element 5503, the second magnetic element 5502, and the fourth magnetic element 5504 are located on both sides of the third support element 5230, the corresponding first coil 5511, third coil 5513, second coil 5512, and fourth coil 5514 are also located on both sides of the third support element 5230. In other words, in the direction of the optical axis extension 5001, the fourth coil 5514 is located between the first optical element 5300 and the first opening 5113, and the first optical element 5300 is located between the first opening 5113 and the first coil 5511. Furthermore, in the direction of the second axis extension 5002, the first optical element 5300 is located between the first coil 5511 and the third coil 5513. The first coil 5511, the third coil 5513, the second coil 5512, and the fourth coil 5514 are located at different heights. That is, in the direction extending from the second axis 5002, the first coil 5511, the third coil 5513, the second coil 5512, and the fourth coil 5514 do not overlap, and the corresponding first magnetic element 5501, the third magnetic element 5503, the second magnetic element 5502, and the fourth magnetic element 5504 do not overlap. This reduces the size of the optical element driving mechanism 5000 in a specific direction, thus achieving miniaturization.

[0159] The first sensing element 5521, the second sensing element 5522, the third sensing element 5523, and the fourth sensing element 5524 can be used to sense the movement of the movable part 5200 relative to the fixed part 5100, such as the linear movement of the movable part 5200 relative to the fixed part 5100. The first sensing element 5521, the second sensing element 5522, the third sensing element 5523, and the fourth sensing element 5524 may include, for example, a Hall effect sensor, a magnetoresistive effect sensor, a giant magnetoresistive effect sensor, a tunneling magnetoresistive effect sensor, or a magnetic flux sensor.

[0160] In some embodiments, the first coil 5511, the second coil 5512, the third coil 5513, and the fourth coil 5514 respectively surround the first sensing element 5521, the second sensing element 5522, the third sensing element 5523, and the fourth sensing element 5524. Furthermore, since the first sensing element 5521 and the third sensing element 5523 are arranged along the second axis 5002, they can also be used to sense the rotation of the movable part 5200 relative to the fixed part 5100. The second sensing element 5522 and the fourth sensing element 5524 are also arranged along the second axis 5002, and they can also be used to sense the rotation of the movable part 5200 relative to the fixed part 5100.

[0161] Since the magnetic elements and coils in this embodiment can overlap in the direction of the optical axis 5001, the size of the optical element driving mechanism 5000 in other directions (e.g., the direction in which the second axis 5002 extends) can be reduced, thereby achieving miniaturization.

[0162] In summary, this disclosure provides an optical element driving mechanism, including a movable part, a fixed part, and a driving assembly. The movable part is used to connect to a first optical element having an optical axis. The movable part is movable relative to the fixed part. The driving assembly is used to drive the movable part to move relative to the fixed part. When viewed along the optical axis, the optical element driving mechanism has an elongated structure. Therefore, optical image stabilization or autofocus functions can be achieved, and miniaturization can also be achieved.

[0163] The specific relative positions and size relationships of the components disclosed in this disclosure not only enable the optical component drive mechanism to achieve thinning 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 matching different optical modules, and further utilize each optical module to achieve a multi-stage anti-shake system to greatly improve the anti-shake effect.
