Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of the description herein.

[0038] Furthermore, this application is required to be understood not only through the actual terms used, but also through the meaning implied by each term.

[0039] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0040] This application provides an aperture embodiment. (See reference...) Figures 1 to 5 The aperture 110 provided in this application embodiment includes: an elastic substrate 111 and a plurality of light-shielding sheets 112.

[0041] The elastic matrix 111 extends in a ring shape, with its two ends being a first end 1111 and a second end 1112, respectively. In other words, the elastic matrix 111 is a non-closed ring structure, with the first end 1111 and the second end 1112 disconnected. Therefore, the elastic matrix 111 can elastically expand or elastically contract by driving the first end 1111 and the second end 1112 to move relative to each other along the circumferential direction of the elastic matrix 111.

[0042] Each light-shielding plate 112 is distributed around the elastic substrate 111 along its circumferential direction. In the light-transmitting direction of the aperture 110, any two adjacent light-shielding plates 112 are staggered, with their orthographic projections overlapping or adjacent to each other. The orthographic projections of each light-shielding plate 112 form a light-shielding ring 113, the central region of which is the light-transmitting area 114. In other words, any two adjacent light-shielding plates 112 are staggered in the height direction of the aperture 110 to prevent interference between them during the elastic expansion or contraction of the elastic substrate 111. Therefore, when the first end 1111 and the second end 1112 move relative to each other along the circumferential direction of the elastic substrate 111, the elastic substrate 111 can elastically expand or contract, thereby changing the aperture of the light-transmitting area 114.

[0043] It should be noted that in the light transmission direction of aperture 110, "the orthographic projections of any two adjacent light-shielding plates 112 overlap or are adjacent" can be understood as follows: the two adjacent light-shielding plates are the first light-shielding plate and the second light-shielding plate, respectively. In the circumferential direction of the elastic substrate 111, the edge portion of the first light-shielding plate near the edge of the second light-shielding plate is the first edge portion, and the edge portion of the second light-shielding plate near the edge of the first light-shielding plate is the second edge portion. In the light transmission direction of aperture 110, the orthographic projection of the first edge portion coincides with the orthographic projection of the second edge portion. Alternatively, in the light transmission direction of aperture 110, the orthographic projection of the contour line of the first edge portion near the second edge portion coincides with the orthographic projection of the contour line of the second edge portion near the first edge portion. That is, in the light transmission direction of aperture 110, the orthographic projection of the first edge portion is adjacent to the orthographic projection of the second edge portion.

[0044] In this manner, in the embodiments of this application, multiple light-shielding plates 112 are distributed around the elastic substrate 111 along its circumferential direction. Thus, by driving the first end 1111 and the second end 1112 to move relative to each other, the elastic substrate 111 can elastically expand or contract, thereby adjusting the aperture of the light-transmitting area 114 of the aperture 110. Compared with apertures in related technologies, the aperture 110 provided in this embodiment eliminates the complex linkage mechanism, achieving a reduction in aperture weight. This further prevents the aperture from damaging the lens. Furthermore, the linkage mechanism included in apertures in related technologies is prone to damage due to its complex mechanical structure; while the aperture 110 provided in this embodiment mainly consists of an elastic substrate 111 and multiple light-shielding plates 112, with a simple mechanical structure and high reliability.

[0045] It should be noted that in related technologies, the aperture is driven to contract or expand via a linkage mechanism. To facilitate driving the aperture to contract or expand using a single driver, a dedicated power distribution mechanism is required to distribute power to each linkage mechanism, making the entire driving structure of the aperture relatively complex. However, the solution provided in this application only requires driving the elastic substrate 111 to elastically contract or expand, thus simplifying the overall structure of the aperture 110.

[0046] refer to Figure 1 In some embodiments, each light-shielding sheet 112 is disposed on the inner surface of the elastic substrate 111, and each light-shielding sheet 112 protrudes toward the center of the elastic substrate 111. Exemplarily, the elastic substrate 111 may be formed by rolling up a sheet material. For example, the sheet material may be rolled into a ring. Furthermore, the light-shielding sheets 112 may all be disposed on the inner surface of the elastic substrate 111.

[0047] In addition, refer to Figure 5 In other embodiments, the elastic substrate 111 may also be connected to the middle portion of the light-shielding sheet 112. In the embodiments of this application, the elastic substrate 111 mainly serves to connect the light-shielding sheet 112 and limit the surrounding arrangement of the light-shielding sheet 112. The specific part of the light-shielding sheet 112 to which the elastic substrate 111 is connected can be flexibly set according to actual needs.

[0048] refer to Figure 3 In some embodiments, in the light transmission direction of the aperture 110, a plurality of adjacent light-shielding plates 112 located at the first end 1111 form a first step 1121; and a plurality of light-shielding plates 112 located at the second end 1112 form a second step 1122. When the elastic substrate 111 is in an elastically contracted state, the first step 1121 and the second step 1122 are opposite to each other. In this way, by having the first step 1121 and the second step 1122 opposite to each other, interference between the light-shielding plates 112 at the first end 1111 and the light-shielding plates 112 at the second end 1112 can be prevented when the elastic substrate 111 is in an elastically contracted state.

[0049] Specifically, refer to Figure 3 When the elastic matrix 111 is in an elastically contracted state, each light-shielding sheet 112 forming the first step 1121 is positioned opposite to each light-shielding sheet 112 forming the second step 1122. (Reference) Figure 1 When the elastic matrix 111 is in an elastically expanded state, the light-shielding sheet 112 forming the first step 1121 near the end of the second step 1122 is opposite to the light-shielding sheet 112 forming the second step 1122 near the end of the first step 1121.

[0050] refer to Figure 1For example, a first force F1 can be applied to the first end 1111 and a second force F2 can be applied to the second end 1112 to cause the first end 1111 and the second end 1112 to move relative to each other.

[0051] refer to Figure 5 In some embodiments, the aperture 110 may further include a telescopic driver 115. One end of the telescopic driver 115 is connected to the first end portion 1111, and the other end is connected to the second end portion 1112. Thus, the telescopic driver 115 can be used to drive the first end portion 1111 and the second end portion 1112 closer together or further apart, thereby adjusting the aperture of the light-transmitting area 114. Furthermore, the first end portion 1111 and the second end portion 1112 can be driven by any other driving device capable of driving their relative movement, which will not be listed here.

[0052] In some embodiments, the aperture of the light-transmitting area 114 is at its maximum when the elastic substrate 111 is not subjected to external force. Furthermore, the aperture of the light-transmitting area 114 can be reduced by driving the first end 1111 and the second end 1112 to move relative to each other, causing the elastic substrate 111 to elastically contract. Further, after the external force is removed, the elastic substrate 111 elastically expands, causing the light-transmitting area 114 to return to its maximum size.

[0053] In other embodiments, the aperture of the light-transmitting area 114 is at its minimum when the elastic substrate 111 is not subjected to external force. Furthermore, the elastic substrate 111 can be elastically expanded by driving the first end 1111 and the second end 1112 to move relative to each other, thereby increasing the aperture of the light-transmitting area 114. Further, after the external force is removed, the elastic substrate 111 elastically contracts, causing the light-transmitting area 114 to return to its minimum size.

[0054] In other embodiments, when the elastic substrate 111 is not subjected to external force, the aperture of the light-transmitting area 114 is of medium size. Furthermore, the elastic substrate 111 can be elastically expanded by driving the first end 1111 and the second end 1112 closer together, thereby increasing the aperture of the light-transmitting area 114; or, the elastic substrate 111 can be elastically contracted, thereby decreasing the aperture of the light-transmitting area 114. Further, after the external force is removed, the elastic substrate 111 returns to its original state, causing the light-transmitting area 114 to return to its medium size.

[0055] In some embodiments, the portion of the light-shielding plate 112 connected to the elastic substrate 111 can be an arc surface, and the side of the light-shielding plate 112 facing the center of the elastic substrate 111 can also be an arc surface. Other sidewalls of the light-shielding plate 112 can be flexibly configured according to actual needs, and will not be listed in detail here. Furthermore, it should be noted that in cases where the light-shielding accuracy requirement of the aperture 110 is not high, the portion of the light-shielding plate 112 connected to the elastic substrate 111 need not be an arc surface, and the side of the light-shielding plate 112 facing the center of the elastic substrate 111 need not be an arc surface. It should also be noted that if the edge of the light-transmitting area 114 is not smooth enough, for example, the effect of the uneven edge of the light-transmitting area 114 can be eliminated by cropping the edges of the captured image.

[0056] This application provides a camera module. (See reference...) Figures 6 to 11 The camera module 100 provided in this application embodiment includes any aperture 110 provided in this application embodiment.

[0057] In some embodiments, the camera module 100 further includes a lens 140 and a lens driver 150. Exemplarily, the lens driver 150 may be a focusing motor. For example, the lens driver 150 may be a voice coil motor. The lens driver 150 is drivenly connected to the lens 140, and an aperture 110 is located on the light-incident side of the lens 140. Optionally, the aperture 110 may be connected to the housing of the lens driver 150.

[0058] It should be noted that in related technologies, the aperture is directly mounted on the lens. This poses a risk of lens damage when the aperture is relatively heavy. The solution provided in this application embodiment allows the aperture 110 to be connected to the housing of the lens driver 150. This allows the housing of the lens driver 150 to provide support for the aperture 110, thereby improving the problem of lens damage caused by the aperture being mounted on the lens in related technologies.

[0059] Furthermore, in some embodiments, the camera module 100 further includes a first traction rope 121 and a second traction rope 122. The first traction rope 121 is connected to a first end 1111, and the second traction rope 122 is connected to a second end 1112. The first traction rope 121 is used to pull the first end 1111, and the second traction rope 122 is used to pull the second end 1112, so that the first end 1111 and the second end 1112 move relative to each other along the circumferential direction of the elastic matrix 111.

[0060] In some embodiments, the camera module 100 further includes a first winder 123 and a second winder 124. The first winder 123 is connected to the first traction rope 121 to wind up or release the first traction rope 121, and the second winder 124 is connected to the first traction rope 121 to wind up or release the second traction rope 122.

[0061] For example, the first winding device 123 includes a first rotary drive element and a first drum. The first rotary drive element is driven to the first drum, and the first traction rope 121 is wound around the first drum. Thus, the first traction rope 121 can be wound or released by driving the first drum to rotate through the first rotary drive element.

[0062] For example, the second winding device 124 includes a second rotary drive element and a second drum. The second rotary drive element is driven to the second drum, and the second traction rope 122 is wound around the second drum. Thus, the second traction rope 121 can be wound or released by driving the second drum to rotate through the second rotary drive element.

[0063] In other embodiments, the first traction rope 121 may be made of an electrically controlled telescopic material. For example, the electrically controlled telescopic material may be an electrically conductive shrinkage shape memory alloy. In this way, when the first traction rope 121 is energized, the length of the first traction rope 121 shortens, thereby pulling the first end 1111.

[0064] Similarly, the second traction rope 122 can be made of an electrically controlled telescopic material. For example, the electrically controlled telescopic material can be an electrically conductive shrinkage shape memory alloy. In this way, when the second traction rope 122 is energized, the length of the second traction rope 122 shortens, thereby pulling the second end 1112.

[0065] In addition, in other embodiments, the first traction rope 121 and the second traction rope 122 may also be made of other materials that can be controlled to stretch and contract, which will not be listed here.

[0066] refer to Figure 7 In some embodiments, the second traction rope 122 is arranged symmetrically along the radial direction of the elastic substrate 111. This improves the force balance of the aperture 110.

[0067] refer to Figure 6 and Figure 7In some embodiments, the camera module 100 further includes a plurality of first elastic support members 131. One end of each first elastic support member 131 is connected to the aperture 110, and the other end is connected to the mounting portion of the camera module 100. The aperture 110 is supported on the mounting portion by the plurality of first elastic support members 131. Exemplarily, the mounting portion is located on the housing of the lens driver 150. In other words, the aperture 110 can be supported on the housing of the lens driver 150 by the plurality of first elastic support members 131.

[0068] refer to Figures 8 to 11 In some embodiments, the camera module 100 further includes a connecting ring 125, a third traction rope 126, a plurality of elastic connectors 127 and a plurality of second elastic supports 132.

[0069] Each of the second elastic support members 132 has one end connected to the connecting ring 125 and the other end connected to the mounting portion of the camera module 100. An aperture 110 is fitted inside the connecting ring 125. One end of an elastic connector 127 is connected to the aperture 110 and the other end is connected to the connecting ring 125. The aperture 110 is mounted on the connecting ring 125 via multiple elastic connectors 127. For example, the mounting portion is located in the housing of the lens driver 150. In other words, the connecting ring 125 is supported on the housing of the lens driver 150 via multiple second elastic support members 132. Furthermore, the aperture 110 is mounted on the connecting ring 125 via multiple elastic connectors 127.

[0070] Furthermore, the third traction rope 126 is connected to the connecting ring 125, and the extension direction of the third traction rope 126 is opposite to the direction of the resultant force of the tension of the first traction rope 121 and the tension of the second traction rope 122. For example, the first traction rope 121 applies a first force F1 to the first end 1111, the second traction rope 122 applies a second force F2 to the second end 1112, and the third traction rope 126 applies a third force F3 to the connecting ring 125. In this way, by balancing the tension of the third traction rope 126, the tension of the first traction rope 121, and the tension of the second traction rope 122, the aperture 110 is prevented from deviating from the optical axis of the lens 140 under the pull of the first and second traction ropes. Alternatively, if the aperture 110 deviates from the optical axis of the lens 140, the tension of each traction rope can be adjusted to pull the connecting ring 125, thereby making the optical axis of the aperture 110 approximately coincide with the optical axis of the lens 140.

[0071] In some embodiments, the camera module 100 further includes a third winder 128. The third winder 128 is connected to a third traction rope 126 to wind or release the third traction rope 126. Exemplarily, the third winder 128 includes a third rotary drive element and a third drum. The third rotary drive element is drivenly connected to the third drum, and the third traction rope 126 is wound around the third drum. Thus, the third traction rope 126 can be wound or released by driving the third drum to rotate through the third rotary drive element.

[0072] It should be noted that, when the aperture 110 includes a telescopic actuator 115 and the camera module 100 includes a first traction rope 121 and a second traction rope 122, the driving scheme in which the telescopic actuator 115 drives the aperture 110 to adjust the aperture of the light-transmitting area 114, and the driving scheme in which the traction rope drives the aperture 110 to adjust the aperture of the light-transmitting area 114, can be used as alternatives to each other. The camera module 100 can choose to drive the aperture 110 with either the telescopic actuator 115 or the traction rope, depending on actual needs.

[0073] This application provides an electronic device, including any of the camera modules 100 provided in this application.

[0074] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0075] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of this application, the scope of which is defined by the appended claims and their equivalents.
