Description

Technical Field

[0001] This invention relates to optical devices, and more particularly to an image capturing device. Background Technology

[0002] With the widespread use of electronic devices, users' demands for various functions of electronic devices are becoming increasingly diversified. Taking the image capturing device that is usually configured on electronic devices as an example, in addition to basic image quality, users also have the key consideration of whether the image capturing device has the function of adjusting various optical parameters (such as adjusting focus or aperture). However, in order to enable the image capturing device to have the function of adjusting optical parameters, the components of the image capturing device are becoming more and more numerous, and the configuration space required is also increasing. Under this situation, how to maintain optical quality and stable product reliability under the premise of limited configuration space is an important issue. Summary of the Invention

The optical image stabilization actuator is connected to the photosensitive component displaceable perpendicular to the optical axis relative to the actuation module.

[0100] See Figure 1 , Figure 1 This is a schematic diagram of the appearance of an embodiment of the image capturing device of the present invention. The image capturing device is used to be installed in an electronic device to capture images, including but not limited to smartphones, tablet computers, laptops, displays, stand-alone cameras, or drones.

[0101] See Figures 1 to 5 , Figure 2 This is an exploded three-dimensional structural diagram of an embodiment of the image capturing device of the present invention. Figure 1 ; Figure 3 This is an exploded three-dimensional structural diagram of an embodiment of the image capturing device of the present invention. Figure 2 ; Figure 4This is an exploded three-dimensional structural diagram of an embodiment of the image capturing device of the present invention. Figure 3 ; Figure 5 For along Figure 1 A cross-sectional view drawn along section line 5-5. The image capturing device includes an actuation module 10, a first lens module 20, a second lens module 30, an aperture module 40, a photosensitive element 50, and an optical image stabilization actuator 60. The first lens module 20 is disposed within the actuation module 10 and is displaced along the optical axis L by the actuation module 10. The second lens module 30 is fixedly disposed outside the actuation module 10, and the aperture module 40 is fitted over the second lens module 30. The optical image stabilization actuator 60 can cause the photosensitive element 50 to displace perpendicularly to the optical axis L relative to the first lens module 20 and the second lens module 30.

[0102] See Figure 2 and Figure 3 The actuation module 10 is used to drive the first lens module 20 to shift parallel to the optical axis L, thereby changing the focal length of the image capturing device. The actuation module 10 can be, but is not limited to, a voice coil motor (VCM), a microelectromechanical system (MEMS), a piezoelectric system, or a shape memory alloy. The actuation module 10 provides the image capturing device with a better imaging position, enabling clear images to be captured even when the subject is at different object distances.

[0103] See Figure 3 and Figure 4 The actuation module 10 includes a base 11 and a lens carrier 12, the lens carrier 12 being disposed within the base 11 with displacement parallel to the optical axis L. In some embodiments, the base 11 is a hollow structure with a rectangular cube appearance and a top surface 111. The top surface 111 is a planar structure for the second lens module 30 or the aperture module 40 to rest against stably. In addition, the top surface 111 also has a through-hole 1111 that penetrates and connects to the interior so that the first lens module 20 can be exposed through the through-hole 1111. In these embodiments, the through-hole 1111 is circular in shape.

[0104] In some embodiments where the actuation module 10 is a voice coil motor, a coil is provided on the lens carrier 12, and a magnetic component is provided on the inner side of the base 11. The coil on the lens carrier 12 can interact with the magnetic component on the inner side of the base 11, causing the lens carrier 12 to be linearly displaced relative to the base 11.

[0105] See Figures 3 to 5The first lens module 20 is an optical component that allows light reflected from an object to enter the image capturing device from the outside and improves light quality. The first lens module 20 is disposed within the base 11 and connected to the lens carrier 12, which can drive the first lens module 20 to move parallel to the optical axis L. In some embodiments, the first lens module 20 includes a first lens barrel 21 and at least one first lens element 22, with the first lens barrel 21 disposed within the lens carrier 12 and the first lens element 22 disposed within the first lens barrel 21. In these embodiments, the lens carrier 12 has an inner surface, the shape of which corresponds to the external shape of the first lens barrel 21 of the first lens module 20, and the first lens barrel 21 can be cured and bonded to the inner surface of the lens carrier 12 by dispensing adhesive.

[0106] See Figures 2 to 6 , Figure 6 This is a partial cross-sectional schematic diagram of an embodiment of the image capturing device of the present invention. The second lens module 30 is an optical component that allows light reflected by an object to enter the interior of the image capturing device from the outside and improves the light quality. The second lens module 30 is disposed outside the base 11. In some embodiments, the second lens module 30 includes a second lens barrel 31 and at least one second lens 32, with the second lens module 30 abutting against the top surface 111 of the base 11 via the second lens barrel 31, and the second lens 32 disposed inside the second lens barrel 31. In these embodiments, the second lens module 30 and the first lens module 20 are arranged on the optical axis L, and the second lens module 30 can be assembled onto the top surface 111 of the base 11 via an AA (Active Alignment) process.

[0107] See Figures 1 to 3 The aperture module 40 has an entrance aperture, and the optical axis L can pass through the center of the entrance aperture of the aperture module 40. In some embodiments, the aperture module 40 is a variable aperture module, that is, the size of the entrance aperture of the aperture module 40 can be changed to adjust the amount of light entering the image capturing device through the entrance aperture, thereby changing the aperture value of the image capturing device and providing different depth-of-field imaging effects.

[0108] See Figures 3 to 6 The aperture module 40 is fitted over the second lens module 30 and disposed on the base 11. In some embodiments, the aperture module 40 is fitted over the second lens module 30 and disposed on the base 11 through the second lens module 30, that is, the second lens module 30 abuts against the base 11, and the aperture module 40 abuts against the second lens module 30. In this way, the relative positions of the second lens module 30 and the aperture module 40 relative to the base 11 do not change, and the relative position of the aperture module 40 relative to the second lens module 30 also does not change, thereby ensuring that the aperture module 40 can provide a variable aperture function.

[0109] See Figures 2 to 3 In some embodiments where the aperture module 40 is a variable aperture module, the aperture module 40 as a whole includes a first end 401 and a second end 402 opposite to each other, and the aperture module 40 includes a plurality of blades 423. Each blade 423 is displaceably disposed at the first end 401, and the aperture module 40 is sleeved on the second lens module 30 with the second end 402. In these embodiments, one end of each blade 423 is disposed at the first end 401 of the aperture module 40, and the other end of each blade 423 together defines the entrance aperture. The optical axis L can pass through the center of the entrance aperture, and the aperture module 40 can drive each blade 423 to displace to change the size of the entrance aperture.

[0110] See Figure 5 and Figure 7 , Figure 7 This is an exploded three-dimensional structural diagram of an embodiment of the image capturing device of the present invention. Figure 4 The photosensitive component 50 is disposed on the side of the actuation module 10's base 11 facing away from the second lens module 30. In these embodiments, the base 11 includes a bottom surface 112 opposite to the top surface 111. The photosensitive component 50 includes a substrate 51 and a photosensitive element 52. The photosensitive element 52 is electrically connected to the substrate 51. The photosensitive component 50 is disposed on the bottom surface 112 of the base 11, and the optical axis L passes through the photosensitive element 52. Thus, light from outside the image capturing device, after passing through the first lens module 20 and the second lens module 30, can be focused onto the photosensitive element 52, enabling the photosensitive element 52 to sense and acquire an image.

[0111] In some embodiments, the substrate 51 may be a PCB (Printed Circuit Board) to maintain the flatness of the photosensitive element 52 after it is mounted on the substrate 51, but the present invention is not limited thereto. The substrate 51 may also be any other structure capable of connecting the photosensitive element 52. For example, the substrate 51 may also be an FPC (Flexible Printed Circuit). Specifically, the substrate 51, which is implemented as an FPC, may be attached to a reinforcing member (e.g., a metal reinforcing member), and the photosensitive element 52 may be attached to the reinforcing member and electrically connected to the substrate 51, thereby maintaining the flatness of the photosensitive element 52 through the reinforcing member.

[0112] In some embodiments, the photosensitive element 52 may be, but is not limited to, a charge-coupled device (CCD), a complementary metal-oxide-semiconductor (CMOS) device, or a silicon photonics chip. That is, in the image capturing device of the present invention, the photosensitive element 52 refers to any optical component capable of photoelectric conversion after receiving light reflected by an object. In one embodiment, the photosensitive element 52 can be mounted on the substrate 51 using a COB (Chip On Board) process, or assembled on the substrate 51 using FC (Flip Chip) flip-chip technology.

[0113] See Figure 5 and Figure 7 The optical image stabilization actuator 60 is a sensor-shift stabilization actuator. It senses the offset of the actuation module 10 and moves the photosensitive element 52 to correct the offset of the actuation module 10. The optical image stabilization actuator 60 is connected to the photosensitive element 50 and can cause the photosensitive element 50 to displace relative to the actuation module 10 perpendicular to the optical axis L.

[0114] See Figure 5 and Figure 7 In some embodiments, the optical image stabilization actuator 60 includes a fixed member 61 and a movable member 62. The fixed member 61 is connected to the actuation module 10, and the movable member 62 is connected to the photosensitive component 50. The movable member 62 can be displaced relative to the fixed member 61 perpendicular to the optical axis L. In this way, the optical image stabilization actuator 60 can drive the photosensitive component 50 to displace relative to the actuation module 10 perpendicular to the optical axis L, thereby compensating for the offset of the actuation module 10.

[0115] See Figure 7 In some embodiments, the fixed member 61 and the movable member 62 are arranged vertically along a direction parallel to the optical axis L, but the present invention is not limited to this. In other embodiments, the fixed member 61 and the movable member 62 may also be arranged at intervals in a direction perpendicular to the optical axis L. Furthermore, the fixed member 61 and the movable member 62 may be connected by, but not limited to, flexible wires or shape memory metal, thereby allowing the movable member 62 to suspend within the accommodating space between the first housing 81 and the second housing 82, ensuring its mobility. Here, the driving force of the optical anti-shake actuator 60 may be achieved by driving elements disposed around the fixed member 61 and / or the movable member 62. The driving elements may be, but are not limited to, shape memory alloys (SMA) or electromagnetic driving elements. In an embodiment where the driving element is a shape memory alloy, when a bias voltage is applied to the shape memory alloy, the shape memory alloy will undergo a change in length or shape, thereby generating a driving force.

[0116] Therefore, the first lens module 20 and the second lens module 30 are respectively disposed inside and outside the actuation module 10. The actuation module 10 only needs to move the first lens module 20 to provide zoom function, which can reduce the weight of the first lens module 20 and the load on the actuation module 10, improve the driving performance and imaging optical quality of the actuation module 10. Furthermore, the aperture module 40 is fitted through the second lens module 30 and stably disposed outside the actuation module 10 to maintain its relative position with the second lens module 30, providing a variable aperture effect in a minimal space configuration, satisfying the requirements of lightweight and miniaturized configuration. In addition, the overall image capturing device is also equipped with an optical image stabilization actuator 60 to provide image stabilization function and improve optical quality.

[0117] See Figures 2 to 4 In some embodiments, the second lens barrel 31 of the second lens module 30 includes a cylindrical body 311 and a ring edge 312. The ring edge 312 is connected to the edge of the cylindrical body 311 and extends along a plane perpendicular to the optical axis L. In these embodiments, the second lens module 30 has the ring edge 312 of the second lens barrel 31 abutting against the top surface 111 of the base 11 of the actuation module 10, thereby increasing the contact area between the second lens module 30 and the top surface 111 of the base 11 and improving the stability of the second lens module 30.

[0118] See Figures 1 to 4 In one embodiment, the image capturing device further includes a patch 70, which is disposed on the top surface 111 of the base 11 of the actuation module 10. The patch 70 has a flat structure, and the second lens module 30 is attached to the patch 70. The additionally provided patch 70 can further ensure the flatness of the attachment position of the second lens module 30 and improve stability.

[0119] See Figure 4 To ensure the flatness of the patch 70, this can be achieved through the selection of the patch 70's material. Specifically, the patch 70 preferably needs to have sufficient strength and flatness to stably support the second lens module 30 and the aperture module 40. Sufficient strength ensures that the patch 70 maintains its flatness after supporting the second lens module 30 and the aperture module 40. In some embodiments, the patch 70 is made of metal, such as, but not limited to, stainless steel. In some embodiments where the patch 70 is made of metal, the patch 70 has a plurality of meshes 71. The meshes 71 on the metal patch 70 allow the patch 70 to be formed by stamping and absorb stress during the stamping process to maintain the flatness of the patch 70. It is worth noting that the meshes 71 on the patch 70 are not limited to a regular or irregular arrangement.

[0120] See Figures 2 to 5In some embodiments of the image capturing device that include a patch 70, the second lens module 30 is attached to the patch 70 with a ring edge 312, thereby ensuring that the second lens module 30 can be positioned on a stable plane. In this embodiment, one end of the aperture module 40 is attached to the side of the ring edge 312 opposite to the base 11.

[0121] See Figure 5 and Figure 6 In some embodiments, the second lens module 30 has opposing light-incident surfaces 301 and 302. In some embodiments where the second lens module 30 includes a plurality of second lenses 32, the light-incident surfaces 301 and 302 of the second lens module 30 are located at the two opposing ends of the second lens barrel 31. When the second lens module 30 is disposed on the base 11 of the actuation module 10, in a direction parallel to the optical axis L, the light-out surface 302 of the second lens module 30 is closer to the first lens module 20 than the light-incident surface 301.

[0122] See Figures 4 to 6 The second lens module 30 abuts against the patch 70 on the top surface 111 of the base 11 of the actuator module 10 with the annular edge 312 of the second lens barrel 31. The second end 402 of the aperture module 40 abuts against the annular edge 312 of the second lens barrel 31 of the second lens module 30.

[0123] See Figure 5 and Figure 6 In these embodiments, the aperture module 40 includes an aperture driving module 41 and a blade module 42, with the aperture driving module 41 sleeved around the blade module 42. The aperture driving module 41 includes a base 411 and a driving element 412. The base 411 has an annular structure and one end abuts against the seat body 11. The driving element 412 may be a circuit board containing a coil. The driving element 412 is disposed on the base 411 along the contour of the base 411, and the coil of the driving element 412 passes through the base 411 and faces the blade module 42.

[0124] See Figure 5 and Figure 6The blade module 42 includes a support 421, a rotating member 422, and multiple blades 423. The support 421 has a circular structure and is disposed inside the base 411 and sleeved outside the second lens module 30. That is, the support 421 is located between the base 411 and the second lens module 30, and one end of the support 421 abuts against the annular edge 312 of the second lens barrel 31 of the second lens module 30. The rotating member 422 has a circular structure and is rotatably disposed on the support 421. The rotating member 422 is provided with a corresponding member (e.g., metal or magnet) that can be attracted by magnetic force. The magnetic characteristics of the coil controlled by the driving element 412 are used to attract the corresponding member on the rotating member 422 to drive the rotating member 422 to rotate. Each blade 423 is rotatably disposed at the end of the rotating member 422 away from the annular edge 312. In this way, the rotating part 422 and its blades 423 can be driven by the driving element 412 of the aperture driving module 41, thereby changing the size of the light entrance aperture.

[0125] See Figure 6 In these embodiments, the rim 312 of the second lens barrel 31 of the second lens module 30 has a first outer diameter D1, and the base 411 of the aperture module 40 has a second outer diameter D2, the second outer diameter D2 of the base 411 being smaller than the first outer diameter D1 of the rim 312. Thus, when the base 411 of the aperture module 40 is disposed on the second lens barrel 31 of the second lens module 30, the base 411 of the aperture module 40 can completely abut against the rim 312 of the second lens barrel 31 of the second lens module 30. Based on the second lens module 30 being stably disposed on the base 11, the aperture module 40 can also be stably disposed on the base 11 via the second lens module 30.

[0126] See Figures 4 to 6 In one embodiment, the aperture module 40 further includes an outer cover 43 and a decorative plate 44. The outer cover 43 is fitted over the base 411 and extends to the first end 401. The decorative plate 44 is an annular sheet and is disposed on the support 421 to cover a portion of each blade 423. The outer cover 43 and the decorative plate 44 can shield the adjacent gaps between the components, reduce the chance of dust or foreign objects entering the aperture module 40, and improve the flatness of the appearance of the aperture module 40.

[0127] See Figure 4 and cooperate Figure 7 and Figure 8 , Figure 8This is a partial structural schematic diagram of an embodiment of the image capturing device of the present invention. In some embodiments, the image capturing device further includes a housing assembly 80, which includes a first housing 81 and a second housing 82. The first housing 81 and the second housing 82 are mated to jointly define an accommodating space. The base 11 of the actuation module 10 is fixed to the first housing 81, and the photosensitive component 50 is displaceably accommodated in the accommodating space. Thus, the actuation module 10 is stably disposed in the first housing 81, and the optical image stabilization actuator 60 can drive the photosensitive component 50 to move within the accommodating space. The overall image capturing device is modularly configured, thereby improving the applicability of the image capturing device for use in various electronic devices.

[0128] In some embodiments of the image capturing device that include a housing assembly 80, the first housing 81 has a through-hole 811, the shape of which corresponds to the external shape of the base 11. The base 11 of the actuation module 10 is housed in the through-hole 811 and is stably positioned therein. In these embodiments, the fixing member 61 of the optical image stabilization actuator 60 can be fixedly disposed on the bottom surface 112 of the base 11, thereby positioning the actuation module 10 and the fixing member 61 in a fixed and stable position.

[0129] See Figure 5 and Figure 7 In some embodiments of the image capturing device that include a housing assembly 80, the photosensitive assembly 50 further includes a flexible flat cable 53 and a carrier 54. The flexible flat cable 53 is electrically connected to the photosensitive element 52. The carrier 54 is disposed on the substrate 51, and the carrier 54 covers one side of the photosensitive element 52 and surrounds the photosensitive element 52. Here, the photosensitive assembly 50 can be connected to the movable member 62 of the optical image stabilization actuator 60 through the carrier 54. The movable member 62 drives the photosensitive assembly 50 to move through the carrier 54. In this way, since the movable member 62 drives the carrier 54 surrounding the photosensitive element 52 to move, it can be ensured that the displacement of the photosensitive element 52 corresponds to the displacement of the movable member 62, thereby improving the image stabilization compensation capability.

[0130] See Figure 7 and Figure 8 In some embodiments where the photosensitive component 50 includes a support 54, the other side of the support 54 includes a limiting groove 541, the shape of which corresponds to the external shape of the movable member 62 of the optical image stabilization actuator 60. In these embodiments, the movable member 62 can be stably accommodated and fixed within the limiting groove 541 of the support 54, thereby increasing the engagement area between the movable member 62 and the support 54, and improving the certainty and stability of the displacement of the photosensitive component 50 by the optical image stabilization actuator 60.

[0131] See Figure 5 and cooperate Figure 7 and Figure 8In some embodiments where the photosensitive component 50 includes a carrier 54, the carrier 54 has two limiting grooves 541 on the other side. For clarity, the two limiting grooves 541 on the carrier 54 will be referred to below as the first limiting groove 541A and the second limiting groove 541B. As explained above, the shape of the first limiting groove 541A of the carrier 54 corresponds to the external shape of the movable member 62 of the optical anti-shake actuator 60 to accommodate the movable member 62. The second limiting groove 541B is formed by further recessing the bottom of the first limiting groove 541A, that is, the second limiting groove 541B and the first limiting groove 541A are located at different heights.

[0132] See Figure 5 In these embodiments, the photosensitive component 50 of the image capturing device further includes a filter 55. The shape of the second limiting groove 541B corresponds to the external shape of the filter 55, and the filter 55 can be accommodated in the second limiting groove 541B to be disposed on the support 54. Here, when the photosensitive component 50 is connected to the movable member 62, the filter 55 remains on the support 54 and is closer to the photosensitive element 52 than the movable member 62, ensuring that when the movable member 62 moves the photosensitive component 50, the filter 55 remains between the object side and the imaging side.

[0133] See Figure 7 and Figure 8 In some embodiments, the flexible flat cable 53 surrounds the outer periphery of the carrier 54 in a configuration perpendicular to the substrate 51. In this configuration, the length of the flexible flat cable 53 in the direction parallel to the optical axis L is greater than the height of the carrier 54 in the same direction. In these embodiments, a portion of the flexible flat cable 53 corresponds to the carrier 54, with one side of the cable 53 adjacent to the substrate 51 and the other side protruding from the carrier 54. A slot 531 is provided between the two sides of the flexible flat cable 53, and the slot 531 is perpendicular to the optical axis L. The portion of the flexible flat cable 53 corresponding to the carrier 54 is bonded to the carrier 54 with an adhesive layer, and the slot 531 on the cable 53 allows the cable 53 to move perpendicular to the optical axis L, ensuring that the carrier 54 can be displaced by the movable element 62 of the optical anti-shake actuator 60.

[0134] See Figure 7 and Figure 8In some embodiments, the carrier 54 further includes a plurality of limiting posts 542, which extend in a direction perpendicular to the optical axis L and are disposed on two opposite outer surfaces of the carrier 54. In these embodiments, the flexible flat cable 53 has a plurality of sleeves 532 on the side adjacent to the substrate 51, and the flexible flat cable 53 passes through each limiting post 542 through each sleeve 532. Therefore, even when the adhesive layer between the flexible flat cable 53 and the carrier 54 deteriorates, falls off, or is damaged, the limiting posts 542 can still provide a basic limiting effect for the flexible flat cable 53 to prevent it from falling off, thereby improving the stability of the overall structural configuration.

[0135] See Figure 9 , Figure 9 For along Figure 1 A cross-sectional view drawn along section line 9-9. In some embodiments, the image capturing device further includes a sensing component 90 that senses vibration, thereby enabling the optical image stabilization actuator 60 to perform image stabilization compensation based on the sensing component 90's sensing. In this embodiment, the sensing component 90 includes a first sensing element 91 and a second sensing element 92. Here, the first sensing element 91 is disposed on the first housing 81, and the second sensing element 92 is disposed on the substrate 51 facing the first sensing element 91. Thus, the first sensing element 91 and the second sensing element 92 can sense the relative displacement between them, thereby providing a basis for the optical image stabilization actuator 60 to perform displacement compensation.

[0136] In some embodiments, the side of the first housing 81 facing the second housing 82 has a plurality of grooves 812, the shape of which corresponds to the shape of the first sensing element 91. In this embodiment, the first sensing element 91 is housed within the grooves 812, thereby enabling the first sensing element 91 to reliably move in sync with the first housing 81 and the actuation module 10 thereon, and to accurately reflect the amount of hand tremor offset.

[0137] In some embodiments, the combination of the first sensing element 91 and the second sensing element 92 may be, but is not limited to, a Hall sensor and a magnet.

[0138] The lens carrier 12 of the actuation module 10 is not limited to displacement only along the direction parallel to the optical axis L. In some embodiments, the lens carrier 12 of the actuation module 10 can also be displaced along a plane perpendicular to the optical axis L. In this way, the actuation module 10 can drive the first lens module 20 to move along three mutually perpendicular directions through the lens carrier 12, thereby improving the reliability of optical axis focusing.

[0139] See Figure 10 and Table 1, Figure 10 This is a schematic diagram showing the configuration of the first lens module 20 and the second lens module 30 according to a specific embodiment of the image capturing device of the present invention; Table 1 shows the configuration according to... Figure 10 The image capturing device in this embodiment applies to the optical parameters of the front lens.

[0142] In this embodiment, the image capturing device has a 1-inch image sensor (16mm diagonal), a 7-element lens assembly, and an aperture value (F. No.) of 1.9. The first lens module 20 includes three first lenses 22 (22A, 22B, 22C), and the second lens module 30 includes four second lenses 32 (32A, 32B, 32C, 32D). The four second lenses (32A, 32B, 32C, 3D) and the three first lenses (22A, 22B, 22C) are arranged sequentially along the optical axis L from the object side A to the image side B. According to this embodiment, the image capturing device has a maximum digital field of view (FOV) of 85 degrees, a total optical length (TTL) (the distance between the second lens 32A closest to the object side A and the imaging IMG) of 10.45 mm, a back focal length (BFL) of 0.8 mm, an image height of 1.28 mm, an optical distortion value of less than 3.0%, a relative illumination (RI) of 15%, a lateral color difference of less than 2 μm, a zoom stroke of 250 μm, and a chief ray angle (CRA) of 39 degrees. Therefore, the image capturing device is not only suitable for use in thin and light electronic devices but also possesses a certain level of imaging optical quality. Furthermore, the diameter DA of the second lens 32A closest to the object side A in the direction perpendicular to the optical axis L can be reduced to 4.6 mm, thereby reducing the size of the opening for assembling the image capturing device and improving its applicability.
