[0002] Currently, variable aperture is a technology that can adjust the amount of light entering the lens, allowing users to take more suitable photos under different lighting conditions. Among them, the main visual impact of the change in aperture size is the change in depth of field.

[0003] In the related art, the current variable aperture is generally adjusted by a set of blades. Specifically, multiple blades in a set of blades rotate together to change the size of the aperture. However, the blades are prone to get stuck when rotating, affecting the user experience. Summary of the invention

[0004] The purpose of the present disclosure is to provide an aperture structure, which can solve the technical problem that blades are prone to getting stuck.

[0005] In order to achieve the above-mentioned purpose, the present disclosure provides an aperture structure, including a base, blades and a shielding assembly, wherein the blades have a light-transmitting hole, and the shielding assembly and the light-transmitting hole form a polygonal first aperture hole, wherein the blades and / or the shielding assembly are movably arranged on the base in a first direction to be able to change the aperture of the first aperture hole.

[0006] Optionally, the blades and the shielding assembly are movably disposed on the base in a first direction.

[0007] Optionally, the number of the blades is at least two, and at least two of the blades are stacked together with the shielding assembly in a second direction, and the second direction is perpendicular to the first direction, wherein the shielding assembly and at least two of the light-transmitting holes together form a polygonal first aperture hole.

[0008] Optionally, the number of the blades is two, and the shielding component and the two light-transmitting holes together form a first aperture hole in the shape of a regular hexagon.

[0009] Optionally, the shielding assembly includes two baffles, each of which is movably disposed on the base in a first direction, and each of which has a straight edge.

[0010] The light-transmitting hole has a triangular first sub-hole, two first sides of the first sub-hole form a vertex, the midline of the first sub-hole at the vertex extends along a first direction, and when the blade moves, the two first sides on the same side of the two first sub-holes can be arranged crosswise,

[0011] The two straight edges of the two baffles and the two first sub-holes together form the first aperture hole.

[0012] Optionally, the two straight sides of the two baffles are adjacent in the first direction.

[0013] Optionally, the baffle is configured as a rectangular plate.

[0014] Optionally, the blades are arranged between the base and the baffle.

[0015] Optionally, the substrate has a through hole, and the projection of the first aperture hole in the second direction is arranged to be located in the through hole.

[0016] The light-transmitting hole has a second sub-hole connected to the first sub-hole, and when the blade moves, two of the second sub-holes can form an avoidance hole.

[0017] When the blade moves until the projection of the through hole in the second direction is located in the avoidance hole, the through hole is configured as a second aperture hole.

[0018] Optionally, the through hole is configured as a round hole.

[0019] Optionally, the second sub-hole has five second sides connected in sequence, and when the blade moves, two of the second sub-holes can form an octagonal avoidance hole.

[0022] Through the above technical solution, in the aperture structure provided by the present invention, when the shielding component moves in the first direction, the relative position of the shielding component and the light-transmitting hole will change, so that the shielding amount and shielding position of the light-transmitting hole by the shielding component will change, thereby changing the aperture of the first aperture hole. Similarly, when the blade moves in the first direction, or when the blade and the shielding component both move in the first direction, the shielding amount and shielding position of the light-transmitting hole by the shielding component will also change, thereby also changing the aperture of the first aperture hole. Here, compared with the related art in which the blade adopts a rotating method to adjust the aperture of the aperture, the blade of the present invention can adopt a linear motion method to adjust the aperture of the first aperture hole, and the blade will basically not get stuck when moving in a linear motion. Moreover, in the mode in which the shielding component moves and the blade remains stationary, the blade will not get stuck either. Therefore, the aperture structure of the present invention can solve the technical problem that the blade is prone to getting stuck.

[0023] In addition, since the shielding assembly and / or the blades use a linear motion method to adjust the aperture of the first aperture hole, it is conducive to the stepless adjustment of the aperture of the first aperture hole. In addition, when the first aperture hole is arranged in a polygonal manner, when the shielding assembly and / or the blades move along the first direction, it is also conducive to the stepless adjustment of the aperture of the first aperture hole.

DETAILED DESCRIPTION

[0035] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, directional words such as "first direction, second direction" may refer to Figure 1 In the XY coordinate system, specifically, the X direction refers to the first direction, and the Y direction refers to the second direction. "Inside and outside" refer to the inside and outside of the contour of each component itself. The terms "first and second" are used to distinguish one element from another element, and do not have order and importance. In addition, when the following description refers to the drawings, the same figure numbers in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0037] According to an exemplary embodiment of the present disclosure, an aperture structure is provided, referring to Figures 1 to 4 as well as Figure 6 and Figure 7 As shown in the figure, the aperture structure includes a base 1, blades 2 and a shielding assembly 3, the blades 2 have a light-transmitting hole 21, the shielding assembly 3 and the light-transmitting hole 21 form a polygonal first aperture hole 10, wherein the blades 2 and / or the shielding assembly 3 are movably arranged on the base 1 in a first direction to be able to change the aperture of the first aperture hole 10.

[0038] Through the above technical solution, in the aperture structure provided by the present disclosure, when the shielding component 3 moves in the first direction, the relative position of the shielding component 3 and the light-transmitting hole 21 will change, so that the shielding amount and shielding position of the light-transmitting hole 21 of the shielding component 3 will change, thereby changing the aperture of the first aperture hole 10. Similarly, when the blade 2 moves in the first direction, or when the blade 2 and the shielding component 3 both move in the first direction, the shielding amount and shielding position of the light-transmitting hole 21 of the shielding component 3 will also change, thereby also changing the aperture of the first aperture hole 10. Here, compared with the related art in which the blade adopts a rotating method to adjust the aperture of the aperture, the blade 2 of the present disclosure can adopt a linear motion method to adjust the aperture of the first aperture hole 10, and the blade 2 will basically not be stuck when moving in a linear motion. Moreover, in the mode in which the shielding component 3 moves and the blade 2 remains stationary, the blade 2 will not be stuck either, so the aperture structure of the present disclosure can solve the technical problem that the blade 2 is prone to being stuck.

[0039] In addition, since the shielding component 3 and / or the blade 2 use a linear motion method to adjust the aperture of the first aperture hole 10, it is conducive to the stepless adjustment of the aperture of the first aperture hole 10. In addition, when the first aperture hole 10 is arranged in a polygonal manner, when the shielding component 3 and / or the blade 2 moves along the first direction, it is also conducive to the stepless adjustment of the aperture of the first aperture hole 10.

[0040] It should be noted that the first aperture hole 10 in the present disclosure which is a "polygon" can be understood as a first aperture hole having at least three sides, for example, the first aperture hole 10 can be a triangle, a quadrilateral, etc. In addition, the present disclosure does not limit the specific structure of the shielding component 3, and the present disclosure will be described in detail in the following embodiments. In addition, the present disclosure does not limit the specific structure of the driving structure for driving the shielding component 3 or the blade 2 to move, for example, the driving structure can include a linear motor, and the linear motor can drive the shielding component 3 or drive the blade 2 to move in the first direction. Of course, the driving structure can also include an electromagnetic driving component, wherein the electromagnetic driving component can include a first electromagnetic component and a second electromagnetic component, one of the first electromagnetic component and the second electromagnetic component is set as the base 1, and the other is set on the shielding component 3 or the blade 2, and the first electromagnetic component and the second electromagnetic component are spaced apart in the first direction, and when the first electromagnetic component and the second electromagnetic component are energized, the two can attract each other with attraction or repel each other with repulsion, thereby, the shielding component 3 or the blade 2 can also be moved in the first direction using the electromagnetic driving component.

[0041] In the exemplary embodiment of the present disclosure, referring to Figures 1 to 4 as well as Figure 6 and Figure 7 As shown in , the blade 2 and the shielding assembly 3 are both movably arranged on the base 1 in the first direction. In this way, when the blade 2 and the shielding assembly 3 are both moved along the first direction, the change in the relative position between the light-transmitting hole 21 and the shielding assembly 3 can facilitate the keeping of the central axis of the first aperture hole 10 relative to the base while achieving the aperture adjustment of the first aperture hole 10, that is, facilitate the keeping of the position of the central axis of the first aperture hole 10 unchanged. For example, when the aperture of the first aperture hole 10 changes from a first value to a second value, the central axis of the first aperture hole 10 still remains at the same position.

[0042] In the exemplary embodiment of the present disclosure, referring to Figures 1 to 4 As shown in , the number of blades 2 can be at least two, and at least two blades 2 and the shielding component 3 are stacked together in the second direction, and the second direction is perpendicular to the first direction, wherein the shielding component 3 can be together with at least two light-transmitting holes 21 to form a polygonal first aperture hole 10. In this way, by providing at least two blades 2, the number of light-transmitting holes 21 can be increased, thereby, through the cooperation of the shielding component 3 and the at least two light-transmitting holes 21, it is helpful to enrich the changes in the shape of the first aperture hole 10, that is, it is helpful to make the first aperture hole 10 be constructed as a variety of polygonal holes, thereby, the adaptability of the aperture structure can be improved.

[0043] In other embodiments of the present disclosure, reference Figure 6As shown in , in an embodiment in which the number of blades 2 is one, the shielding assembly 3 may include a baffle 31, and the light-transmitting hole 21 may be configured as a triangular hole. At this time, the first aperture hole 10 may be configured as a triangular hole. When both the blade 2 and the baffle 31 move along the first direction, the central axis of the first aperture hole 10 may be kept stationary relative to the base 1 while the aperture of the first aperture hole 10 is adjusted. Here, according to some embodiments, the light-transmitting hole 21 may be configured as an equilateral triangular hole, so that when the central axis of the first aperture hole 10 is stationary relative to the base 1, the aperture of the first aperture hole 10 may also be ensured to be an equilateral triangular hole when it changes.

[0044] In other embodiments of the present disclosure, reference Figure 7 As shown in , in an embodiment in which the number of blades 2 is one, the shielding assembly 3 may include two baffles 31, each baffle 31 is movably disposed on the base 1 in the first direction, and the light-transmitting hole 21 may be constructed to have at least two square sub-holes arranged along the first direction and connected in sequence, and the apertures of any two square sub-holes are different. At this time, the first aperture hole 10 may be constructed as a square hole. When the blade 2 and the two baffles 31 are both moved along the first direction, the two baffles 31 may cooperate with different square sub-holes, thereby, the aperture adjustment of the first aperture hole 10 may also be achieved. Here, when the blade 2 and the two baffles 31 are both moved along the first direction, the central axis of the first aperture hole 10 may also be stationary relative to the base 1.

[0045] In some embodiments of the present disclosure, the blades 2 and the shielding assembly 3 are both movably disposed on the base 1 in the first direction, and the number of the blades 2 is at least two. Figures 1 to 4 As shown in , the number of blades 2 can be two, and the shielding component 3 and the two light-transmitting holes 21 can together form a first aperture hole 10 in the shape of a regular hexagon. Here, it is well known to those skilled in the art that the closer the aperture is to a circle, the softer the out-of-focus effect of the photo taken by the lens assembly. Therefore, compared to the first aperture hole 10 in the shape of a triangle, a square or a regular pentagon, the present disclosure designs the first aperture hole 10 as a regular hexagonal hole, so that the lens assembly with the first aperture hole 10 in the shape of a regular hexagon can take photos with a softer out-of-focus effect. In addition, the number of blades 2 is two, so that the aperture structure can be designed to be thinner in the second direction while ensuring the soft out-of-focus effect, thereby facilitating the aperture structure to be arranged in a structure with a small installation space, such as in a lens assembly. Of course, in other embodiments, when the blades 2 and the shielding assembly 3 are movably arranged on the base 1 in the first direction, and the number of blades 2 is multiple, the shielding assembly 3 and the multiple light-transmitting holes 21 can together form a first aperture hole 10 that is a regular polygon with more than six sides, so as to make the out-of-focus effect of the photo softer.

[0046] In an optional embodiment, in the embodiment where the first aperture hole 10 is a regular hexagonal hole, reference Figures 1 to 4 As shown in , the shielding assembly 3 may include two baffles 31, each baffle 31 is movably disposed on the base 1 in the first direction, and each baffle 31 has a straight edge 311, so that the two baffles 31 can be close to or away from each other in the first direction, so that the two straight edges 311 can be moved away from or close to each other in the first direction. The light-transmitting hole 21 may have a first sub-hole 211 in a triangular shape, and the two first edges 2111 of the first sub-hole 211 are surrounded by a vertex 2112. The midline of the first sub-hole 211 at the vertex 2112 extends along the first direction. When the blade 2 moves, the two first edges 2111 on the same side of the two first sub-holes 211 can be cross-arranged, and the two straight edges 311 of the two baffles 31 and the two first sub-holes 211 together form a first aperture hole 10. Here, reference is made to Figure 3 As shown in FIG. , the aperture of the first aperture hole 10 is relatively small, referring to Figure 4 As shown in FIG. 1 , the aperture of the first aperture hole 10 is relatively large. Figure 3 and Figure 4 As shown in , when the two first edges 2111 on the same side of the two first sub-holes 211 are arranged crosswise, when the two vertex angles 2112 are far away from each other and the two baffles 31 are far away from each other, the aperture of the first aperture hole 10 can be increased. When the two vertex angles 2112 are close to each other and the two baffles 31 are close to each other, the aperture of the first aperture hole 10 can be reduced. Thus, when the two baffles 31 and the two blades 2 move along the first direction, the aperture of the first aperture hole 10 can be infinitely adjusted. In addition, when the two baffles 31 and the two blades 2 move simultaneously, the aperture of the first aperture hole 10 can be continuously adjusted, thereby, the aperture of the first aperture hole 10 can be adjusted in a wide range while the baffles 31 and the blades 2 have a small moving stroke. In this way, the aperture structure of the present disclosure can be designed to be miniaturized, and when applied to the lens assembly, it occupies less space, and the wide range adjustment of the aperture of the first aperture hole 10 can enable the lens assembly to be applied to a variety of usage scenarios.

[0047] In some embodiments of the present disclosure, reference Figures 1 to 4 As shown in , the two straight edges 311 of the two baffles 31 may be adjacent to each other in the first direction. Thus, the moving stroke of the baffles 31 can be shortened, which is beneficial to the miniaturization of the aperture structure.

[0048] In some embodiments of the present disclosure, reference Figure 2 As shown in , the baffle 31 can be constructed as a rectangular plate. Therefore, when the aperture structure is assembled, any side of the baffle 31 can be used as a straight side 311. Therefore, constructing the baffle 31 as a rectangular plate is conducive to the installation of the baffle 31.

[0049] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown in , the thicknesses of the two baffles 31 in the second direction may be the same, thereby facilitating the two baffles 31 to move away from or approach each other.

[0050] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown in , the blade 2 can be arranged between the base 1 and the baffle 31. Thus, compared with the method of arranging the baffle 31 between two blades 2, arranging the blade 2 between the base 1 and the baffle 31 is conducive to the smooth movement of each blade 2, that is, such a design can prevent the baffle 31 from affecting the smoothness of the movement of the blade 2. Of course, the baffle 31 can also be arranged between two blades 2.

[0051] In some embodiments of the present disclosure, reference Figure 1 , Figure 2 as well as Figure 5 As shown in , the base 1 may have a through hole 11, and the projection of the first aperture hole 10 in the second direction is set to be located in the through hole 11, that is, the light transmission area of ​​the first aperture hole 10 is smaller than the light transmission area of ​​the through hole 11, and the first aperture hole 10 transmits light through the through hole 11. In this way, the light transmission hole 21 may have a second sub-hole 212 connected to the first sub-hole 211, and when the blade 2 moves, the two second sub-holes 212 can enclose the avoidance hole 20, and when the blade 2 moves until the projection of the through hole 11 in the second direction is located in the avoidance hole 20, the through hole 11 can be constructed as a second aperture hole. That is, the area of ​​the avoidance hole 20 is larger than the light transmission area of ​​the through hole 11. In this way, when the first aperture hole 10 cannot meet the use scenario of the lens assembly, the two blades 2 can be made to form an avoidance hole 20, and the two baffles 31 can be placed in a position to avoid the through hole 11. At this time, the through hole 11 can be constructed as a second aperture hole. Here, the light-transmitting area of ​​the through hole 11 is larger than the light-transmitting area of ​​the first aperture hole 10. Therefore, constructing the through hole 11 as the second aperture hole can meet the use scenario of the lens assembly under a large aperture. In addition, since the second sub-hole 212 is connected to the first sub-hole 211, the two blades 2 can quickly form the avoidance hole 20 under a relatively small movement stroke, thereby facilitating the miniaturization of the aperture structure. Here, the present disclosure does not limit the specific shape of the through hole 11. Therefore, the present disclosure can be adaptively designed as needed. Therefore, the second aperture hole is set to different shapes to facilitate the application of the lens assembly to more use scenarios.

[0052] In an optional embodiment, referring to Figures 1 to 5As shown in , the through hole 11 can be configured as a circular hole. Therefore, when the through hole 11 is configured as a second aperture hole, the out-of-focus effect of the photo taken by the lens can be made softer. Of course, in other embodiments, the through hole 11 can also be configured as an octagonal hole or a hexagonal hole, and the present disclosure does not limit this.

[0053] In an optional embodiment, referring to Figure 1 , Figure 2 as well as Figure 5 As shown in , the second sub-hole 212 has five second sides 2121 connected in sequence. When the blade 2 moves, the two second sub-holes 212 can form an octagonal avoidance hole 20. In this way, the octagonal avoidance hole 20 is conducive to avoiding the through hole 11, so that the through hole 11 is configured as a second aperture hole. Of course, in other embodiments, the second sub-hole 212 can also be configured as a semicircular hole, and the two second sub-holes 212 can form a circular avoidance hole 20. Alternatively, the two avoidance holes 20 can also form a hexagonal or decagonal avoidance hole 20, which is not limited in the present disclosure.

[0054] In other embodiments of the present disclosure, reference Figure 1 , Figure 2 as well as Figure 5 As shown in , the base 1 may have a through hole 11, and the projection of the first aperture hole 10 in the second direction is set to be located in the through hole 11, that is, the light transmission area of ​​the first aperture hole is smaller than the light transmission area of ​​the through hole, and the first aperture hole transmits light through the through hole. In this way, the light transmission hole 21 may have a second sub-hole 212 connected to the first sub-hole 211, and when the blade 2 moves, the two second sub-holes 212 can enclose an avoidance hole 20, and the shape and aperture of the avoidance hole 20 are the same as those of the through hole 11. When the blade 2 moves until the central axis of the avoidance hole is colinear with the central axis of the through hole 11, the through hole 11 can be constructed as a second aperture hole. In this way, when the first aperture hole 10 cannot meet the use scenario of the lens assembly, the two blades 2 can be made to form an avoidance hole 20, and the two baffles 31 can be placed in a position to avoid the through hole. At this time, the through hole 11 can be constructed as a second aperture hole. Here, the light-transmitting area of ​​the through hole 11 is larger than the light-transmitting area of ​​the first aperture hole 10. Therefore, constructing the through hole 11 as the second aperture hole can meet the use scenario of the lens assembly under a large aperture. In addition, since the second sub-hole 212 is connected to the first sub-hole 211, the two blades 2 can quickly form the avoidance hole 20 under a relatively small movement stroke, thereby facilitating the miniaturization of the aperture structure. Here, the present disclosure does not limit the specific shape of the through hole 11. Therefore, the present disclosure can be adaptively designed as needed. Therefore, the second aperture hole is set to different shapes to facilitate the application of the lens assembly to more use scenarios.

[0055] In an optional embodiment, the through hole 11 can be configured as a circular hole, the second sub-hole 212 can be configured as a semicircular hole, and the two second sub-holes 212 can form a circular avoidance hole 20. Therefore, when the through hole 11 is configured as a second aperture hole, the out-of-focus effect of the photo taken by the lens can be made softer.

[0056] In some other embodiments of the present disclosure, the base 1 may have a through hole 11, and the projection of the first aperture hole 10 in the second direction is arranged to be located in the through hole 11, that is, the light-transmitting area of ​​the first aperture hole 10 is smaller than the light-transmitting area of ​​the through hole 11, and the first aperture hole 10 transmits light through the through hole 11. In this way, when the blades 2 and the baffle 31 are moved to be arranged staggered with the through hole 11, the through hole 11 can be constructed as a second aperture hole. In this way, when the first aperture hole 10 cannot meet the use scenario of the lens assembly, the blades 2 and the baffle 31 can be placed in a position to avoid the through hole 11. At this time, the through hole 11 can be constructed as a second aperture hole. Here, the light-transmitting area of ​​the through hole 11 is larger than the light-transmitting area of ​​the first aperture hole 10. Therefore, constructing the through hole 11 as a second aperture hole can meet the use scenario of the lens assembly under a large aperture. Here, the present disclosure does not limit the specific shape of the through hole 11, so the present disclosure can be adaptively designed as needed, thereby, the second aperture hole is set to different shapes to facilitate the application of the lens assembly to more usage scenarios.

[0057] In addition, reference Figure 1 and Figure 2 As shown in the figure, the aperture structure may include a base 4 having a light hole 41 having the same shape as the through hole 11, wherein the aperture of the light hole 41 is the same as the aperture of the through hole 11, and the blades 2 and the baffle 31 may be arranged between the base 4 and the substrate 1, thereby improving the stability of the blades 2 and the baffle 31 when moving.

[0058] Next, the present disclosure will introduce the specific use process of the aperture structure in detail in combination with the above specific implementation. First, the base 4, the two baffles 31, the two blades 2 and the base 1 are stacked together in sequence in the second direction. At this time, refer to Figure 2 As shown in , the first aperture hole 10 can be constructed as a regular hexagonal hole, and the aperture of the first aperture hole 10 is relatively small; when the aperture of the first aperture hole 10 needs to be increased, the two vertex angles 2112 of the two blades 2 can be moved away from each other, and the two baffles 31 can be moved away from each other. At this time, reference Figure 3As shown in , the aperture of the first aperture hole 10 is relatively large; when the aperture of the first aperture hole 10 needs to be reduced, the two vertex angles 2112 of the two blades 2 can be brought close to each other, and the two baffles 31 can be brought close to each other, at this time, the aperture of the first aperture hole 10 can be reduced. When the circular through hole 11 needs to be configured as the second aperture hole, the two baffles 31 can be moved to avoid the through hole 11, and the two blades 2 can be moved so that the two second sub-holes 212 surround the octagonal avoidance hole 20, and the projection of the through hole 11 in the second direction is located in the avoidance hole 20. At this time, reference Figure 5 As shown in FIG. 1 , the through hole 11 is configured as a second aperture hole.

[0059] According to a second aspect of the present disclosure, a lens assembly is provided, comprising the aperture structure as described above. The lens assembly has all the beneficial effects of the aperture structure as described above, and the present disclosure will not elaborate on them here. Here, in the embodiment where the lens assembly has the aperture structure as described above, a miniaturized design of the lens assembly can be realized, thereby facilitating the placement of the lens assembly in a terminal such as a mobile phone.

[0060] According to some embodiments, when the lens assembly is actually used, a suitable aperture size can be selected according to different shooting purposes and scenes. Generally speaking: when shooting close-ups of portraits, details of flowers and plants, and other subjects that need to highlight the subject and blur the background, a large aperture can be selected. When shooting scenery, architecture, still life, and other subjects that need to maintain panoramic clarity and a large depth of field, a small aperture can be selected. When shooting night lights, the starry sky, and other subjects that need to produce a starburst effect, a small aperture can be selected.

[0061] According to the second aspect of the present disclosure, a terminal is provided, comprising the lens assembly as described above. The terminal has all the beneficial effects of the above-mentioned lens assembly, which will not be elaborated in detail in the present disclosure. Here, the present disclosure does not limit the specific type of the terminal.
