Description

Technical Field

[0001] The utility model relates to a light through hole module, a camera module and an electronic device, in particular to a light through hole module suitable for the camera module and the electronic device. Background Art

[0002] As semiconductor processing technology continues to improve, the performance of electronic photosensitive components has increased, allowing pixels to achieve smaller sizes. Therefore, optical lenses with high imaging quality have become indispensable. Furthermore, with the rapid advancement of technology, the application range of electronic devices equipped with optical lenses has become wider, and the requirements for optical lenses have also become more diverse.

[0003] In recent years, camera modules have been incorporated into a wider range of electronic devices, including portable devices like smartphones and action cameras, as well as headsets like augmented reality (AR) and virtual reality (VR), and drones. Furthermore, camera module hardware has been continuously upgraded, with the use of larger sensors and higher-quality optical lenses. While larger sensors offer better image quality, they can also lead to background blur due to a shallower depth of field. Existing variable apertures can be used to adjust the depth of field, thereby adjusting the degree of background blur, and controlling the amount of light entering the optical lens, making the inclusion of variable apertures in optical lenses for electronic devices a promising topic. However, existing optical lenses often fail to consider the space required for the variable aperture during design, resulting in insufficient design margins and poor integration with the variable aperture. This results in large optical lenses and cumbersome assembly processes. Furthermore, there are issues with the variable aperture's tendency to vibrate during operation, and the manufacturing yield of the corresponding structure is low. Therefore, how to improve the matching structure of the variable aperture to meet the current high-standard requirements of electronic devices has become an important issue in the relevant fields.

Furthermore, the design of the plastic surface structure close to the blades effectively reduces blade vibration during operation.

[0010] When Tp satisfies the above conditions, the one-piece molded cover component can significantly improve the pass rate during automated assembly by utilizing a plastic portion of appropriate thickness.

[0105] The following detailed description of the features and advantages of the present invention is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Based on the disclosure of this specification, the scope of the claims, and the accompanying drawings, any person skilled in the art can easily understand the relevant objectives and advantages of the present invention. The following examples further illustrate the concepts of the present invention in detail but are not intended to limit the scope of the present invention in any way.

[0106] The utility model provides a light hole module, which comprises a blade assembly and a cover element in sequence along a central axis.

[0107] The blade assembly comprises a plurality of blades, which form a light-through hole, and the light-through hole has a variable size with the central axis as the center.

[0108] The cover element covers the blade assembly and has a through hole, which is arranged corresponding to the light through hole.

[0109] The cover element includes a plastic surface structure and a metal sidewall structure. The design of the cover element facilitates the overall miniaturization of the light-through hole module and eliminates the assembly process between the plastic surface structure and the metal sidewall structure, thereby significantly increasing the manufacturing yield. The cover element including the plastic surface structure and the metal sidewall structure can be an integrally molded element. The plastic surface structure can be made of plastic, and the metal sidewall structure can be made of metal. The plastic surface structure made of plastic and the metal sidewall structure made of metal can be manufactured using insert molding. However, the present invention is not limited to this.

[0110] The plastic surface structure faces one of the blades and is positioned correspondingly to the blade. This reduces blade lift during rotation, ensuring stable blade travel during operation and precisely controlling the dimensional changes of the light aperture. Parallel to the central axis, the plastic surface structure is closer to the blades than the through-hole and positioned sequentially with them. This proximity of the plastic surface structure to the blades effectively reduces blade vibration during operation.

[0111] The plastic surface structure can be arranged around the through hole. In other words, the plastic surface structure can extend toward the through hole. The plastic surface structure can define the through hole. Thereby, more specific results can be achieved in eliminating stray light, and the excessive reflection of non-imaging light can be reduced more efficiently. Among them, the plastic surface structure can be designed to have a larger area to face the blades. Thereby, it can be ensured that when the light-through hole module is dropped for testing, the blades will not bend abnormally due to external force collision, and the product reliability of the light-through hole module can be improved. Among them, the plastic surface structure can have a bump, and the bump is facing these blades. Through the design of the bump, the plastic surface structure can be closer to the blades, and the jumping of the blades during operation can be further reduced.

[0112] The metal sidewall structure is disposed around the through hole and extends from the plastic surface structure in a direction parallel to the central axis. The metal sidewall structure may also extend from an outer edge of the plastic surface structure in a direction parallel to the central axis.

[0113] The cover element may also include a metal surface structure. The metal surface structure may extend from the metal sidewall structure toward the through-hole. Alternatively, the metal surface structure may extend from the metal sidewall structure toward the central axis. The metal surface structure may define the through-hole. This reduces the volume of the plastic surface structure, thereby increasing injection molding output speed.

[0114] The light aperture module disclosed in the present invention may also include a base. The base may be fixed relative to the cover element. The base may have a first axis structure, and the blades may be movable within a specific range according to the first axis structure to control the size of the light aperture. Alternatively, by changing the relative position of the blades to the first axis structure, the blades can be moved closer to or further away from the central axis, thereby controlling the size of the light aperture. The mechanical coordination between the base and the cover element facilitates automated assembly.

[0115] Each blade may have a first drive hole. The first drive hole may correspond to the first shaft structure, and the first shaft structure may be provided with the first drive hole. The first drive hole may be a strip hole. This reduces excessive dynamic collision between the drive hole and the shaft structure, allowing the blade to maintain a relatively good flatness during durability testing. The plastic surface structure may have a first countersunk hole structure. The first countersunk hole structure may sink away from the first shaft structure and may be arranged in correspondence with the first shaft structure. This further reduces the vibration of the blade during operation and prevents the blade from colliding with surrounding hard objects and causing abnormal deformation and bending during a drop test. The first countersunk hole structure may be a circular hole. The first countersunk hole structure may be a blind hole structure that does not penetrate the cover element but penetrates the plastic surface structure. This ensures that no trace of the hole is visible on the surface of the light-through hole module, preventing the blade from being affected by external temperature and moisture.

[0116] According to the light passing hole module disclosed by the present utility model, it may further include a rotating element. The rotating element can be rotatable around the central axis. The rotating element may have a second shaft structure, and these blades can be linked with the second shaft structure to change the size of the light passing hole. Or it can also be said that by driving the blades to move and / or rotate through the rotating element and cooperating with the first shaft structure, the size of the light passing hole can be changed accordingly.

[0117] Among them, each blade may have a second driving hole. The second driving hole can correspond to the second shaft structure, and the second shaft structure can pass through the second driving hole. The second driving hole can be a circular hole. By this means, it can cooperate with the first driving hole to greatly reduce the relative movement between the driving hole and the shaft structure, and greatly reduce the warping deterioration of the blade, so as to maintain better mechanical transmission accuracy. Among them, the plastic surface structure may have a second counterbore structure. The second counterbore structure can sink in the direction away from the second shaft structure, and the second counterbore structure can be arranged corresponding to the second shaft structure. By this means, the jumping degree of the blade during operation can be further reduced, and when undergoing the drop test, it can avoid the blade from possibly colliding with surrounding hard objects and causing abnormal deformation and folding. Among them, the second counterbore structure can be a slot hole. Among them, the second counterbore structure can be a blind hole structure, which does not penetrate the cover element but penetrates the plastic surface structure. By this means, the hole traces can't be seen on the appearance of the light passing hole module, and the blade can be prevented from being affected by external temperature and moisture.

[0118] According to the light passing hole module disclosed by the present utility model, it may further include a plurality of rolling elements. These rolling elements can be arranged between the base and the rotating element to provide the rotating element with the freedom of rotation. Or it can also be said that the rolling elements can guide the rotating element to rotate relative to the base. By this means, extremely high rotational stability can be provided for the rotating element, and it is not easy to cause unnecessary slight jitter during the rotation process. Moreover, by using the rolling elements, the assembly process of the light passing hole module can be easily detected, and it is also easy to exclude defective products with poor assembly, and can filter out defective products more accurately and effectively. Among them, the rolling elements can be spheres, cylinders, cones, etc., but the present utility model is not limited thereto.

[0119] The thickness of the plastic surface structure in the direction parallel to the central axis is Tp, which can meet the following conditions: 0.0092 mm < Tp ≤ 0.735 mm. By this means, the integrally formed cover element can have a significant improvement in the qualified rate during automated assembly by using the plastic part with an appropriate thickness. Among them, it can also meet the following conditions: 0.036 mm < Tp ≤ 0.58 mm. By this means, a thinner plastic surface structure can be provided, and it can have better molding quality under the production conditions of insert injection molding.

[0120] The maximum diameter of the plastic surface structure perpendicular to the central axis is Φp, and the maximum diameter of the metal sidewall structure perpendicular to the central axis is Φm. These dimensions must meet the following conditions: 0.1 < Φp / Φm ≤ 1.05. This effectively reduces the complexity of the cover component mold design, significantly minimizing the number of failures encountered during the development process and effectively contributing to the mass production feasibility of miniaturized parts. Furthermore, the following condition must also be met: 0.15 ≤ Φp / Φm < 0.975. This allows for optimal dimensional accuracy during miniaturization.

[0121] The height of the metal sidewall structure parallel to the center axis is Hm, which must meet the following conditions: 0.042 mm ≤ Hm < 6.83 mm. This prevents excessive metal sidewall height from interfering with the mold, provides better molding accuracy for the plastic surface structure, and reduces the chance of insert injection molding failure.

[0122] The thickness of the plastic surface structure parallel to the central axis is Tp, and the height of the metal sidewall structure parallel to the central axis is Hm. These meet the following conditions: 0.004 ≤ Tp / Hm < 0.41. This effectively maintains consistent dimensional accuracy during mass production, resulting in excellent mass production stability.

[0123] The present invention provides a camera module comprising the aforementioned light-through hole module and a lens assembly. The lens assembly is arranged in a direction parallel to the central axis and corresponding to the light-through hole. The light-through hole can be an aperture of the camera module.

[0124] The utility model provides an electronic device, which includes the aforementioned camera module.

[0125] The various technical features of the aforementioned aperture module, camera module, and electronic device of the present invention can be configured in combination to achieve corresponding effects.

[0129] The base 11 has a plurality of first shaft structures 11a. The first shaft structures 11a extend toward the rotating element 13, such as Figure 2 shown.

[0130] The rolling element 12 is a sphere, which is disposed between the base 11 and the rotating element 13 to provide the rotating element 13 with a degree of freedom of rotation. Figure 2 shown.

[0131] The rotating element 13 is rotatable around the central axis 10. In other words, the rotating element 13 is rotatable relative to the base 11 by the guidance of the rolling element 12.

Figure 9 and Figure 10 shown.

[0136] The plastic surface structure 152 faces one of the blades 140 and is disposed corresponding to the blade 140. The plastic surface structure 152 is closer to the blades 140 than the through hole 151 in a direction parallel to the central axis 10, and the plastic surface structure 152 is disposed sequentially with the blades 140 in a direction parallel to the central axis 10.

[0137] In this embodiment, the plastic surface structure 152 has a plurality of protrusions 1520. These protrusions 1520 face toward the blades 140, such as Figure 2 and Figure 4 shown.

[0138] The plastic surface structure 152 further has a plurality of first countersunk hole structures 152a. The first countersunk hole structures 152a are sunken in a direction away from the first axis structure 11a, and the first countersunk hole structures 152a are arranged corresponding to the first axis structure 11a.

Figure 50 is a schematic diagram showing an image captured by the electronic device 9 with the camera module 90a at an aperture value of 1.4, and Figure 51 FIG. 1 is a schematic diagram showing an image captured by the electronic device 9 with the camera module 90a at an aperture value of 5.6, wherein the captured image includes a flock of birds flying in front of the church. Figure 50 As shown, when the light hole module 1 of the camera module 90a provides a larger light hole 141, the electronic photosensitive element obtains more light, but the background is more blurred. Figure 51 As shown, when the light hole module 1 of the camera module 90a provides a smaller light hole 141, the electronic photosensitive element receives less light, but can obtain a clearer background. Figure 50 and Figure 51 The image has a narrow viewing angle, allowing camera module 90a to capture moving objects. The autofocus driver drives the lens carrier to quickly and continuously autofocus the object, preventing blurring due to movement away from the focus position. During image capture, camera module 90a can further perform optical zoom on the subject, producing a clearer image. Furthermore, the time-of-flight camera module 90e can obtain depth information from the image. While the electronic device 9 described above includes multiple camera modules 90a, 90b, 90c, 90d, and 90e, the number and configuration of the camera modules are not intended to limit the present invention.

Furthermore, an image signal processor performs image optimization processing to further enhance the image quality produced by lens assembly 80a. Focus assist module 93 may utilize an infrared or laser focus assist system to achieve rapid focus.

[0220] Furthermore, the electronic device 9 can also utilize camera module 90d or camera module 90e for capturing images. When camera module 90d or camera module 90e is capturing, a reminder light 9a may illuminate to alert the user that the electronic device 9 is capturing. The display device 95 may utilize a touch screen or physical capture buttons such as a zoom control key 951 and a focus / photographing key 952, in conjunction with the diverse functions of the image software processor for capturing and processing images. Images processed by the image software processor are displayed on the display device 95. The user can also replay previously captured images using the image playback button 953 on the display device 95, select the appropriate camera module for capturing images using the camera module switching button 954, and adjust the capture conditions for the current scene using the integrated menu button 955.

[0221] Furthermore, the electronic device 9 further includes a circuit board 98, which carries a plurality of electronic components 99. The camera modules 90a, 90b, 90c, 90d, and 90e are electrically connected to the electronic components 99 via connectors 981 on the circuit board 98. The electronic components 99 may include a signal transmission module, which can transmit images to other electronic devices or cloud storage. The signal transmission module can be a wireless Fidelity (WiFi) module, a Bluetooth module, an infrared module, an Internet service module, or an integrated module of multiple signal transmissions, but the present invention is not limited thereto.

[0222] Electronic components 99 may also include a storage unit, random access memory (RAM) to store image signals, a gyroscope, and a position locator to facilitate navigation or positioning of electronic device 9. In this embodiment, the image signal processor, image software processor, and random access memory are integrated into a single-chip system 94, but the present invention is not limited to this configuration. In some other embodiments, the electronic components may be integrated into a camera module or disposed on one of multiple circuit boards. Furthermore, biometric sensor 97 may provide functions such as powering on and unlocking electronic device 9.

[0223] The camera module of the present invention is not limited to smartphones. It can also be used in mobile focus systems, depending on the needs, and features both excellent aberration correction and high-quality imaging. For example, the camera module can be used in a variety of electronic devices, including three-dimensional (3D) image capture, digital cameras, mobile devices, tablet computers, smart TVs, network monitoring equipment, dashcams, backup cameras, multi-lens devices, recognition systems, motion-sensing game consoles, and wearable devices.
