Description

BACKGROUNDField of expertise

[0001] The present disclosure relates to a light-transmitting hole module, a camera module, and an electronic device, particularly to a light-transmitting hole module that can be used in a camera module and an electronic device. Description State of the art

[0002] With the development of semiconductor manufacturing technology, the performance of image sensors has improved and their pixel size has decreased. Therefore, high image quality is now one of the essential features of an optical system. Furthermore, due to rapid technological changes, electronic devices equipped with optical systems are becoming multifunctional for various applications, which has increased the requirements for the functionality of optical systems.

[0003] Recently, camera modules have been used in a growing number of areas in electronic devices, such as wearable devices (e.g., smartphones, action cameras), head-mounted displays for augmented reality (AR) or virtual reality (VR), and aerial cameras. Furthermore, the hardware used in camera modules is continuously being improved, for example, by using larger image sensors and imaging lenses with better image quality. A larger image sensor provides better image quality, but the background of the image may become blurred due to a shallow depth of field. Traditionally, a variable aperture can be used to change the depth of field, thus adjusting the degree of background blur and controlling the amount of incident light. Therefore, the incorporation of a variable aperture into an optical system of an electronic device is becoming a future-oriented topic.However, the conventional optical system is designed without considering the clearance of the variable aperture, resulting in limited design flexibility, poor integration with the variable aperture, excessively large optical system size, and complicated assembly processes, as well as some problems such as the jumping of the variable aperture during operation and low yield rates in the manufacturing of the corresponding structure. Therefore, improving the corresponding variable aperture structure to meet the requirements of high-specification electronic devices is currently an important topic in this field. SUMMARY

DETAILED DESCRIPTION

[0010] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown schematically to simplify the drawing.

[0011] A light-transmitting aperture module provided in the present disclosure includes a diaphragm assembly and a lid member arranged sequentially along a central axis.

[0012] The aperture assembly includes a plurality of apertures that form a translucent hole. The translucent hole has a variable size with reference to the central axis as the center.

[0013] The cover element covers the aperture assembly. The cover element has a through hole that aligns with the translucent hole.

[0014] The lid member includes a plastic surface structure and a metal wall structure. The design of the lid member is advantageous for miniaturizing the overall size of the light-transmitting hole module and eliminating the assembly process of the plastic surface structure and the metal wall structure, thereby significantly increasing the manufacturing yield. Furthermore, the lid member including the plastic surface structure and the metal wall structure can be manufactured in one integrated piece. Furthermore, the plastic surface structure can be made of plastic material, the metal wall structure can be made of metal material, and the plastic surface structure in the plastic material and the metal wall structure in the metal material can be manufactured by insert injection molding. However, the present disclosure is not limited thereto.

[0015] The plastic surface structure can be arranged facing and covering one of the plurality of diaphragms. Therefore, it is advantageous for reducing the floating of the diaphragm during its rotation, so that stable movement of the rotated diaphragm can be ensured to accurately and precisely control the size change of the transmissive hole. In a direction parallel to the central axis, the plastic surface structure can be arranged closer to the plurality of diaphragms than the through-hole and can be arranged in line with the plurality of diaphragms. By arranging the plastic surface structure close to the diaphragms, it is advantageous for effectively reducing the jumping of the diaphragms during their operation.

[0016] The plastic surface structure can be arranged around the through-hole. It can also be considered that the plastic surface structure extends toward the through-hole. The plastic surface structure can define the through-hole. Therefore, it is advantageous for achieving a specific effect in eliminating stray light, effectively reducing excessive reflection of non-imaging light. Furthermore, the plastic surface structure can be designed to have a relatively large area facing the apertures. Therefore, it is advantageous for preventing undesired bending of the apertures due to impact during a drop test of the light-transmitting hole module, thereby increasing the product reliability of the light-transmitting hole module. Furthermore, the plastic surface structure can have a protrusion facing the apertures.This design of the projection is advantageous for locating the plastic surface structure closer to the bezels, thereby further reducing the jumping of the bezels during their operation.

[0017] The metal wall structure is arranged around the through-hole. The metal wall structure extends from the plastic surface structure along a direction parallel to the central axis. Furthermore, the metal wall structure may extend from an outer edge of the plastic surface structure along a direction parallel to the central axis.

[0018] The lid element may further comprise a metal surface structure. The metal surface structure may extend from the metal wall structure toward the through-hole. It is also possible for the metal surface structure to extend from the metal wall structure toward the central axis. The metal surface structure may define the through-hole. Therefore, it is advantageous for reducing the size of the plastic surface structure to accelerate injection molding.

[0019] According to the present disclosure, the light-transmitting hole module may further include a base. The base may be immovable with respect to the lid member. The base may have a first axis structure. The plurality of apertures are movable within a certain range according to the first axis structure to control the size of the light-transmitting hole. It may also be considered that the apertures can be moved close to or away from the central axis by changing the relative position between the apertures and the first axis structure. Therefore, this is advantageous for controlling the size of the light-transmitting hole. Due to the mechanical cooperation of the base and the lid member, automated assembly is more convenient.

[0020] Furthermore, each aperture may include a first guide hole. The first guide holes may be arranged corresponding to the first axis structure, and the first axis structure may be arranged through the first guide holes. Each first guide hole may be an elongated hole. Therefore, this is advantageous for reducing excessive impact between the guide holes and the axis structure during relative movement between them, so that the apertures can still maintain good flatness even after a durability test. Furthermore, the plastic surface structure may include a first recess structure. The first recess structure may be recessed along a direction away from the first axis structure and may be arranged corresponding to the first axis structure.Therefore, it is advantageous for further reducing the cracking of the panels during operation and preventing unwanted deformation or bending of the panels caused by impact with a surrounding hard object during drop testing. Furthermore, the first recess structure may be a circular hole. Furthermore, the first recess structure may be a blind hole structure defined by the plastic surface structure but not defined by the lid member. Therefore, it is advantageous for maintaining the appearance of the translucent hole module without openings, ensuring that the panels are not affected by external temperature and humidity.

[0021] According to the present disclosure, the light-transmitting hole module may further comprise a rotating element. The rotating element is rotatable about the central axis. The rotating element may have a second axis structure. The second axis structure may be connected to the plurality of apertures to vary the size of the light-transmitting hole. It is also contemplated that the size of the light-transmitting hole may be varied by movement and / or rotation of apertures driven by the rotating element in cooperation with the first axis structure.

[0022] Furthermore, each aperture may include a second guide hole. The second guide holes may be arranged so as to be coincident with the second axis structure, and the second axis structure may be arranged through the second guide holes. Each second guide hole may be a circular hole. Therefore, it is advantageous for cooperating with the first guide hole to significantly reduce the relative movement between the guide holes and the axis structure and significantly reduce the deformation of the apertures, thereby maintaining good mechanical transmission accuracy. Furthermore, the plastic surface structure may include a second recess structure. The second recess structure may be recessed along a direction away from the second axis structure and may be arranged so as to be coincident with the second axis structure.Therefore, it is beneficial for further reducing the bounce of the panels during operation and preventing unwanted deformation or bending of the panels caused by impact with a surrounding hard object during drop testing. Furthermore, the second recess structure may be a long hole. Furthermore, the second recess structure may be a blind hole structure defined by the plastic surface structure but not defined by the cover element. Therefore, this is beneficial for maintaining the appearance of the translucent hole module without openings, ensuring that the panels are not affected by external temperature and humidity.

[0023] According to the present disclosure, the translucent hole module may further include a plurality of rollable parts. The plurality of rollable parts may be arranged between the base and the rotating member to provide a rotational degree of freedom of the rotating member. It may also be considered that the rollable parts may cause the rotating member to rotate with respect to the base. Therefore, this is advantageous for ensuring high rotational stability of the rotating member and thereby preventing undesirable slight wobble during its rotation. Therefore, the arrangement of the rollable parts is advantageous for detecting the assembly process of the translucent hole module and thereby effectively and accurately removing and replacing defective components. Furthermore, the rollable parts may be spherical, cylindrical, conical, etc., and the present disclosure is not limited thereto.

[0024] When the thickness of the plastic surface structure along a direction parallel to the central axis is Tp, the following condition can be met: 0.0092 mm (millimeters) < Tp ≤ 0.735 mm. Therefore, this is advantageous for significantly increasing yield by using the plastic part of the one-piece lid element with an appropriate thickness during automated assembly. In addition, the following condition is also met: 0.036 mm < Tp ≤ 0.58 mm. Therefore, this is advantageous for providing a thinner plastic surface structure to achieve good molding quality under the production conditions of insert molding.

[0025] When the maximum diameter of the plastic surface structure along a direction perpendicular to the central axis is Φp and the maximum diameter of the metal wall structure along a direction perpendicular to the central axis is Φm, the following condition can be satisfied: 0.1 < Φp / Φm ≤ 1.05. Therefore, it is beneficial to effectively simplify the mold design of the lid element, significantly increasing the success rate during product development and thus effectively ensuring the feasibility of mass production of miniaturized parts. In addition, the following condition is also satisfied: 0.15 ≤ Φp / Φm < 0.975. Therefore, this is beneficial to optimize the dimensional accuracy of miniaturized parts.

[0026] When the height of the metal wall structure along a direction parallel to the central axis is Hm, the following condition can be met: 0.042 mm ≤ Hm < 6.83 mm. Therefore, this is beneficial to prevent the metal wall structure from being too high and preventing mold interference, thereby providing good molding accuracy of the plastic surface structure and increasing the success rate of insert molding.

[0027] When the thickness of the plastic surface structure along the direction parallel to the central axis is Tp and the height of the metal wall structure along the direction parallel to the central axis is Hm, the following condition can be met: 0.004 ≤ Tp / Hm < 0.41. Therefore, it is beneficial for effectively maintaining the consistency of dimensional accuracy during mass production, thereby achieving good stability of pass production.

[0028] A camera module provided in the present disclosure includes the aforementioned light-transmitting hole module and a lens assembly arranged corresponding to the light-transmitting hole along a direction parallel to the central axis. Furthermore, the light-transmitting hole may form an opening of the camera module.

[0029] An electronic device provided in the present disclosure includes the aforementioned camera module.

[0030] According to the present disclosure, the above features and conditions can be used in numerous combinations to achieve corresponding effects.

The plastic surface structure 152 is arranged closer to the apertures 140 than the through-hole 151 along a direction parallel to the central axis 10 and is arranged in series with the apertures 140 along a direction parallel to the central axis 10.

[0042] In this embodiment, the plastic surface structure 152 has a plurality of projections 1520 facing the panels 140, as shown in the Fig. 2 and Fig. 4 shown.

[0117] Furthermore, the electronic device 9 further includes a circuit board 98 and a plurality of electronic components 99 arranged on the circuit board 98. The camera modules 90a, 90b, 90c, 90d, and 90e are electrically connected to the electronic component 99 via connectors 981 on the circuit board 98. The electronic components 99 may include a signal emission module and may transmit images to another electronic device or cloud storage via the signal emission module. The signal emission module may be a wireless fidelity (WiFi) module, a Bluetooth module, an infrared module, a network service module, or an integrated module for transmitting various signals mentioned above, and the present disclosure is not limited thereto.

[0118] The electronic components 99 may also include a storage unit, a random access memory for storing image information, a gyroscope, and a position locator for facilitating navigation or positioning of the electronic device 9. In this embodiment, the image signal processor, the image software processor, and the random access memory are integrated into a single system-on-chip 94, but the present disclosure is not limited thereto. In some other embodiments, the electronic components may also be integrated into the camera module or arranged on one of the circuit boards. Furthermore, the user can use the biometric identification device 97 to turn on or unlock the electronic device 9.

[0119] The smartphone in this embodiment serves only as an example to show the camera module of the present disclosure installed in the electronic device 9, and the present disclosure is not limited thereto. The camera module can optionally be applied to optical systems with a moving focus. Furthermore, the camera module 8 features good aberration correction and high image quality and can be used for 3D image acquisition (three-dimensional image acquisition) in products such as digital cameras, mobile devices, digital tablets, smart TVs, network monitoring devices, dashboard cameras, vehicle rearview cameras, multi-camera devices, image recognition systems, motion sensor input devices, wearable devices, and other electronic imaging devices.
