Description

TECHNICAL FIELD

[0001] The present application relates to a through hole module, a camera module and an electronic device, in particular, to a through hole module suitable for a camera module and an electronic device. BACKGROUND

[0002] With the advancement of semiconductor process technology, the performance of electronic photosensitive elements is improved, and the pixel size can be smaller. Therefore, optical lenses with high imaging quality are indispensable. In addition, with the rapid development of technology, electronic devices equipped with optical lenses are more widely used, and the requirements for optical lenses are more diverse.

[0003] In recent years, camera modules have been applied to electronic devices in more fields, such as portable devices such as smartphones and action cameras, and head-mounted devices such as augmented reality (AR) and virtual reality (VR), and drones, etc. Moreover, the hardware of the camera module is constantly updated, such as using larger size photosensitive elements and using optical lenses with better image quality. Larger size photosensitive elements can provide users with better imaging quality, but can cause background blur due to shallow depth of field. A variable aperture can be used to change the depth of field to adjust the degree of background blur and control the amount of light entering the optical lens, so that the design of a variable aperture in an electronic device optical lens becomes a forward-looking topic. However, the existing optical lens often does not consider the space for setting the variable aperture when designing, resulting in insufficient design margin and poor integration with the variable aperture, causing the optical lens to be too large in size and the assembly process to be complicated. There are also problems such as the variable aperture jumping when operating and the corresponding structure manufacturing yield being poor. Therefore, how to improve the cooperation structure of the variable aperture to meet the current high-specification requirements of electronic devices has become an important issue in the related field. SUMMARY

[0004] In view of the above-mentioned problems, the present application provides a through hole module with the characteristics of miniaturization, easy assembly, good manufacturing yield and smooth operation, and can be applied to camera modules and electronic devices.

[0005] An aperture module disclosed by an embodiment of the present application comprises, in sequence along a central axis, a vane set and a cover element. The vane set has a plurality of vanes. The vanes form an aperture. The aperture has a variable size centered on the central axis. The cover element covers the vane set. The cover element has a through hole. The through hole is arranged in correspondence with the aperture. The cover element comprises a plastic surface structure and a metal side wall structure. The plastic surface structure faces and is arranged in correspondence with one of the vanes. In a direction parallel to the central axis, the plastic surface structure is closer to the vanes than the through hole and is arranged in sequence with the vanes. The metal side wall structure is arranged around the through hole. The metal side wall structure extends from the plastic surface structure in the direction parallel to the central axis. The thickness of the plastic surface structure in the direction parallel to the central axis is Tp, which satisfies the following condition: 0.0092 mm < Tp ≤ 0.735 mm.

[0006] An aperture module disclosed by another embodiment of the present application comprises, in sequence along a central axis, a vane set and a cover element. The vane set has a plurality of vanes. The vanes form an aperture. The aperture has a variable size centered on the central axis. The cover element covers the vane set. The cover element has a through hole. The through hole is arranged in correspondence with the aperture. The cover element comprises a plastic surface structure and a metal side wall structure. The plastic surface structure faces and is arranged in correspondence with one of the vanes. In a direction parallel to the central axis, the plastic surface structure is closer to the vanes than the through hole and is arranged in sequence with the vanes. The metal side wall structure is arranged around the through hole. The metal side wall structure extends from the plastic surface structure in the direction parallel to the central axis. The maximum diameter of the plastic surface structure in a direction perpendicular to the central axis is Φp, and the maximum diameter of the metal side wall structure in the direction perpendicular to the central axis is Φm, which satisfy the following condition: 0.1 < Φp / Φm ≤ 1.05.

[0007] A camera module disclosed by still another embodiment of the present application comprises the aperture module described above and a lens set. The lens set is arranged in correspondence with the aperture in a direction parallel to the central axis.

[0008] An electronic device disclosed by still another embodiment of the present application comprises the camera module described above.

[0009] The aperture module, the camera module and the electronic device disclosed by the above embodiments, through the design of the cover element, help the overall miniaturization of the aperture module, and the assembly process between the plastic surface structure and the metal side wall structure can be omitted, thus the manufacturing yield can be greatly increased. Moreover, through the design that the plastic surface structure faces and is arranged in correspondence with one of the vanes, the floating of the vanes during rotation can be reduced, and the stroke stability of the vanes during operation can be ensured, so that the size change of the aperture can be accurately controlled. Moreover, through the design that the plastic surface structure is closer to the vanes, the jumping of the vanes during operation can be effectively reduced.

[0010] When Tp satisfies the above condition, the integrally formed cover element can have a significant yield rate improvement in automated assembly using a plastic portion of appropriate thickness.

[0011] When Φp / Φm satisfies the above condition, the complexity of the cover element molding die design can be effectively reduced, the number of failures encountered during development can be greatly reduced, and the mass production feasibility of small-sized parts can be effectively contributed.

[0105] The detailed features and advantages of the present application are described in detail in the embodiments below, which are sufficient to enable any person skilled in the art to understand the technical content of the present application and to implement it, and according to the content disclosed in the specification, the scope of the application and the drawings, any person skilled in the art can easily understand the related purposes and advantages of the present application. The following examples further illustrate the concepts of the present application, but do not limit the scope of the present application in any way.

[0106] The present application provides a through hole module, which comprises a leaf set and a cover element along a central axis in sequence.

[0107] The leaf set has a plurality of leaves. These leaves form a through hole. The through hole has a variable size centered on the central axis.

[0108] The cover element covers the blade set. The cover element has a through hole. The through hole is arranged corresponding to the light passing hole.

[0109] The cover element comprises a plastic surface structure and a metal side wall structure. Through the design of the cover element, the overall size of the light passing hole module can be reduced, and the assembly process between the plastic surface structure and the metal side wall structure can be omitted, thereby greatly increasing the manufacturing yield. The cover element comprising the plastic surface structure and the metal side wall structure can be an integrally formed element. The plastic surface structure can be made of plastic material, and the metal side wall structure can be made of metal material. The plastic surface structure made of plastic material and the metal side wall structure made of metal material can be manufactured by insert molding. However, the present application is not limited thereto.

[0110] The plastic surface structure faces one of the blades and is arranged corresponding to the one of the blades. In this way, the floating of the blades during rotation can be reduced, and the stable travel of the blades during operation can be ensured to accurately control the size change of the light passing hole. In the direction parallel to the central axis, the plastic surface structure is closer to the blades than the through hole and is arranged in sequence with the blades. Through the design of the plastic surface structure close to the blades, the jumping of the blades during operation can be effectively reduced.

[0111] The plastic surface structure can be arranged around the through hole. Alternatively, the plastic surface structure can extend towards the through hole. The plastic surface structure can define the through hole. In this way, the elimination of stray light can have more specific results, and the excessive reflection of non-imaging light can be more effectively reduced. The plastic surface structure can be designed to have a larger area to face the blades. In this way, the blades can not be abnormally bent due to external impact during the drop test of the light passing hole module, and the product reliability of the light passing hole module can be improved. The plastic surface structure can have a protrusion, and the protrusion faces the blades. Through the design of the protrusion, 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 side wall structure is arranged around the through hole. The metal side wall structure extends from the plastic surface structure in the direction parallel to the central axis. The metal side wall structure can also extend from the outer edge of the plastic surface structure in the direction parallel to the central axis.

[0113] The cover element can further comprise a metal surface structure. The metal surface structure can extend from the metal side wall structure towards the through hole. Alternatively, the metal surface structure can extend from the metal side wall structure towards the central axis. The metal surface structure can define the through hole. In this way, the volume of the plastic surface structure can be reduced to speed up the output of injection molding.

[0114] According to the light-through hole module of the present application, the base can be fixed opposite to the cover element. The base can have a first shaft structure, and the blades can be movable within a certain range according to the first shaft structure to control the size of the light-through hole. Alternatively, the size of the light-through hole can be controlled by changing the relative position between the blades and the first shaft structure to make the blades close to or away from the central shaft. The mechanism cooperation between the base and the cover element can facilitate the convenience of automated assembly.

[0115] Each blade can have a first driving hole. The first driving hole can correspond to the first shaft structure, and the first shaft structure can pass through the first driving hole. The first driving hole can be a strip hole. In this way, the excessive dynamic collision between the driving hole and the shaft structure can be reduced, and the blades can still maintain good flatness under durability test. The plastic surface structure can have a first counterbore structure. The first counterbore structure can be sunken in the direction away from the first shaft structure, and the first counterbore structure can be arranged corresponding to the first shaft structure. In this way, the degree of runout of the blades during operation can be further reduced, and abnormal deformation and bending of the blades due to possible collision with surrounding hard objects during drop test can be avoided. The first counterbore structure can be a round hole. The first counterbore structure can be a blind hole structure that does not penetrate the cover element but penetrates the plastic surface structure. In this way, the external appearance of the light-through hole module cannot see the hole marks, and the blades are protected from external temperature and moisture.

[0116] The light-through hole module of the present application can also include a rotating element. The rotating element can be rotatable around the central shaft. The rotating element can have a second shaft structure, and the blades can be connected to the second shaft structure to change the size of the light-through hole. Alternatively, the size of the light-through hole can be changed by moving and / or rotating the blades driven by the rotating element in combination with the first shaft structure.

[0117] Each blade can 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 round hole. In this way, the first driving hole can be combined to greatly reduce the relative movement between the driving hole and the shaft structure, and the warping and degradation of the blades can be greatly reduced, thereby maintaining good mechanical transmission accuracy. The plastic surface structure can have a second counterbore structure. The second counterbore structure can be sunken in the direction away from the second shaft structure, and the second counterbore structure can be arranged corresponding to the second shaft structure. In this way, the degree of runout of the blades during operation can be further reduced, and abnormal deformation and bending of the blades due to possible collision with surrounding hard objects during drop test can be avoided. The second counterbore structure can be a strip hole. The second counterbore structure can be a blind hole structure that does not penetrate the cover element but penetrates the plastic surface structure. In this way, the external appearance of the light-through hole module cannot see the hole marks, and the blades are protected from external temperature and moisture.

[0118] According to the present application, the light hole module can further comprise rolling elements. The rolling elements can be arranged between the base and the rotating element to provide the rotating element with a degree of freedom for rotation. Alternatively, the rolling elements can guide the rotating element to rotate relative to the base. In this way, the rotating element can have a high stability for rotation and is less likely to have unnecessary slight shaking during rotation. Moreover, the use of the rolling elements can make the assembly process of the light hole module easy to be detected and can easily eliminate defective products, so that defective products can be filtered out more accurately and effectively. The rolling elements can be spheres, cylinders, cones, etc., but the present application is not limited thereto.

[0119] The thickness of the plastic surface structure in the direction parallel to the central axis Tp can satisfy the following condition: 0.0092 mm < Tp ≤ 0.735 mm. In this way, the integrally formed cover element can have a significant pass rate improvement in automated assembly using a plastic portion with an appropriate thickness. The thickness of the plastic surface structure in the direction parallel to the central axis Tp can also satisfy the following condition: 0.036 mm < Tp ≤ 0.58 mm. In this way, a thinner plastic surface structure can be provided, and better molding quality can be achieved under the production conditions of insert molding.

[0120] The maximum diameter of the plastic surface structure in the direction perpendicular to the central axis Φp and the maximum diameter of the metal side wall structure in the direction perpendicular to the central axis Φm can satisfy the following condition: 0.1 < Φp / Φm ≤ 1.05. In this way, the complexity of the design of the cover element molding die can be effectively reduced, the number of failures encountered during the development process can be greatly reduced, and the mass production feasibility of small-sized parts can be effectively contributed. The maximum diameter of the plastic surface structure in the direction perpendicular to the central axis Φp and the maximum diameter of the metal side wall structure in the direction perpendicular to the central axis Φm can also satisfy the following condition: 0.15 ≤ Φp / Φm < 0.975. In this way, the size precision of the small-sized part can be optimized.

[0121] The height of the metal side wall structure in the direction parallel to the central axis Hm can satisfy the following condition: 0.042 mm ≤ Hm < 6.83 mm. In this way, the metal side wall structure can be prevented from being too high to interfere with the mold mechanism, and better molding precision of the plastic surface structure can be provided to reduce the probability of failure of insert molding.

[0122] The thickness of the plastic surface structure in the direction parallel to the central axis Tp and the height of the metal side wall structure in the direction parallel to the central axis Hm can satisfy the following condition: 0.004 ≤ Tp / Hm < 0.41. In this way, the consistency of the size precision at the mass production level can be effectively maintained, and good mass production stability can be achieved.

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

[0124] The present application provides an electronic device comprising the aforementioned camera module.

[0125] The technical features of the light hole module, the camera module and the electronic device of the present application can be combined to achieve the corresponding effects.
